Analyses are presented for predicting the strength governed by the plastic tensile instability (PTI) phenomenon in thin-walled cylindrical and spherical pressure vessels constructed of texture- hardening alloys and with or without over-wrapped filaments. These analyses are important in predicting ductile bursting of pressure vessels used in such high-performance applications as high-pressure storage bottles, liquid-propellant tankage, and solid rocket casings. The analyses cover cylindrical pressure vessels subject to any ratio of biaxial stresses. Also means of estimating the effect of finite length is presented. Spherical vessels of texture- hardening material and cylindrical vessels with filaments over wrapped on a texture-hardening metallic substrate are treated as special cases. The analytical results are compared with available experimental results with good success.

Adequate stress transfer between the inorganic reinforcement and surrounding polymeric matrix is essential for achieving enhanced structural integrity and extended lifetime performance of fiber-reinforced composites. The insertion of an elastomeric interlayer helps increase the stress-transfer capabilities across the fiber/matrix interface and considerably reduces crack initiation phenomena at the fiber ends. In this study, admicellar polymerization is used to modify the fiber/matrix interface in glass woven fabric composites by forming thickness-controlled poly(styrene-co-isoprene) coatings. These admicellar interphases have distinct characteristics (e.g., topology and surface coverage) depending on the surfactant/monomer (S/M) ratios used during the polymerization reaction. Overall, the admicellar coatings have a positive effect on the mechanical response of resin transfer molded (RTM), E-glass/epoxy parts. For instance, ultimate tensile strength (UTS) of composites with admicellar sizings improved 50 to 55% over the control desized samples. Interlaminar shear strength (ILSS) also showed increases ranging from 18 to 38% over the same control group. Interestingly, the flexural properties of these composites proved sensitive to the type of interphase formed for various admicellar polymerization conditions. Higher surface coverage and film connectedness in admicellar polymeric sizings are observed to enhance stress transfer at the interfacial region.

Using institutional theory as the foundation, this study examines the role of organizational visibility from a variety of sources (i.e., slack visibility, industry visibility, and visibility to multiple stakeholders) in influencing corporate social performance (CSP). The conceptual framework offers important insights regarding the instrumental motives of managers in performing CSP initiatives. Based on a sample of 124 S&P 500 firms, the authors found that it is a firm’s visibility to stakeholders, rather than its economic performance, that has the larger impact on managers’ decisions regarding how much CSP their firms exhibit. The results show that more profitable firms may not be motivated to engage actively in CSP unless they are under greater scrutiny by various firm stakeholders. The authors also found that organizational slack (estimated as cost of capital) is positively associated with a Social CSP dimension but negatively associated with a Strategic CSP dimension. This research contributes to the current CSP literature by demonstrating that motivations in addition to normative or ethical ones may be at play in the decisions firms make regarding their CSP.

Individuals who are charged for traditional crimes are substantially more likely to plead guilty than individuals who are charged under the same statutes but who are officially involved in terrorism (Smith & Damphousse, 1998). Relying on a structural–contextual theory framework, a quantitative analysis not only confirmed that terrorists plead guilty more often than traditional offenders but that the defendant’s age and number of counts in the indictment are important predictors. Directions for future research are suggested.

The acute and chronic effects of whole-body vibration (WBV) on balance, postural stability, and mobility were evaluated in 21 women with relapsing-remitting multiple sclerosis (MS) randomly assigned to control (n = 9) or experimental (n = 12) groups. To assess acute responses, outcome variables were assessed before and immediately after a session of WBV (five 30-second bouts of vibration; frequency 30 Hz; amplitude 3 mm; 1-minute rest intervals) during their first visit (week 1) using field (Timed-Up and Go; 500-m walk; Berg Balance Scale) and laboratory tests (NeuroCom Balance Master and EquiTest System—Sensory Organization Test, Adaptation Test, Limits of Stability, Modified Clinical Test for Sensory Integration of Balance, Unilateral Stance, Tandem Walk, Step/Quick Turn). Acute responses were also measured after their fifth visit for only the Adaptation and Sensory Organization tests. For the chronic responses, participants were exposed to the WBV protocol once a week, for a total of 5 weeks, and then at week 5, were reassessed with the Adaptation and the Sensory Organization tests. Neither acute nor chronic exposure to the WBV protocols used in this study resulted in significant improvements (P > .05) in balance, postural stability, or mobility as assessed by either field or laboratory tests. However, based on promising results from other studies that have used WBV with other clinical populations, either alone or in conjunction with exercise, additional studies that increase the dose of vibration exposure, both acutely and chronically, should be conducted in patients with MS.

The two-dimensional steady flow of both infinite and finite aspect ratio (length to diameter ratio) fibers suspended in a Newtonian fluid is investigated numeri cally. Forty-five-degree convergent and divergent channel geometries are considered for the analysis. Due to symmetry, only half the channel geometry is considered and the ori entation field is assumed to be planar. The analysis is carried out for the creeping flows where the inertia terms are neglected. Numerical grid generation is used to generate the mesh, and the transformed governing equations in terms of the stream function are solved in the computational domain using a finite difference scheme. In this study, several solu tion strategies for solving the orientation field are investigated. The orientation of individ ual fibers are assumed to be governed by Jeffery's equation. The orientation field, which can be expressed in different forms (i.e., a unit vector, tensorial quantities, or an orienta tion distribution function), is specified by solving the orientation equations along particle paths. A tracing technique is implemented to obtain these particle paths for each grid point in the flow domain. The solution of the orientation field is obtained by using two basic techniques. First, a large number of fibers are considered, and by using analytical expres sions developed to describe the orientation state of one fiber, a statistical orientation distri bution function is generated. Second, tensorial quantities (both second- and fourth-order orientation tensors) are employed to solve for the orientation field. In order to overcome the closure problem occurring in the resulting orientation equations, quadratic approxima tions are used. Maximum orientation angles are reported from both the techniques, and their accuracies are investigated. The maximum orientation angles (i.e., preferred orienta tion) obtained from the second- and fourth-order tensorial solutions are observed to be identical. On the other hand, the degree of fiber alignments that are specified by the indi vidual tensor components differ considerably. Comparison of the solution techniques shows that the accuracy of the preferred angle obtained from statistical solution is depen dent on the number of fibers considered. In addition, the calculations for the finite fiber aspect ratio revealed some discrepancies between the statistical and tensorial results at the regions of rapid fiber tumbling.

The different emphases that theorists and teachers place on the product and process of writing in their accounts of how writers construct meaning have been influenced by different traditions of Western thought that have historically been at odds: Whereas the designative tradition focuses on the ways in which artifacts of speech mediate people's thinking, the expressive tradition focuses on the transformation of inner speech to public speech, thus emphasizing the ways in which the activities of speaking and writing promote changes in consciousness. In this article, through the analysis of the writing of a high school senior, it is argued that these two positions are not mutually exclusive, but rather are complementary aspects of a semiotic view on writing. The primary data set is a “situated protocol”—that is, a think-aloud protocol, including both concurrent and retrospective accounts of writing process, conducted over a 4-month period. Through the protocol analysis and analysis of related data, I examine the ways in which this student's writing experiences reveal the interrelated roles of both designative and expressive functions of writing. The analysis also reveals that the writer found the situated protocol itself to be an enduring means of development and reflection and a tool for meditation.

We analyzed the transcriptome of Escherichia coli K-12 by strand-specific RNA sequencing at single-nucleotide resolution during steady-state (logarithmic-phase) growth and upon entry into stationary phase in glucose minimal medium. To generate high-resolution transcriptome maps, we developed an organizational schema which showed that in practice only three features are required to define operon architecture: the promoter, terminator, and deep RNA sequence read coverage. We precisely annotated 2,122 promoters and 1,774 terminators, defining 1,510 operons with an average of 1.98 genes per operon. Our analyses revealed an unprecedented view of E. coli operon architecture. A large proportion (36%) of operons are complex with internal promoters or terminators that generate multiple transcription units. For 43% of operons, we observed differential expression of polycistronic genes, despite being in the same operons, indicating that E. coli operon architecture allows fine-tuning of gene expression. We found that 276 of 370 convergent operons terminate inefficiently, generating complementary 3′ transcript ends which overlap on average by 286 nucleotides, and 136 of 388 divergent operons have promoters arranged such that their 5′ ends overlap on average by 168 nucleotides. We found 89 antisense transcripts of 397-nucleotide average length, 7 unannotated transcripts within intergenic regions, and 18 sense transcripts that completely overlap operons on the opposite strand. Of 519 overlapping transcripts, 75% correspond to sequences that are highly conserved in E. coli (>50 genomes). Our data extend recent studies showing unexpected transcriptome complexity in several bacteria and suggest that antisense RNA regulation is widespread.

Research studies have shown that digital wireless phones interact with some hearing aids, creating a buzzing noise that may reduce speech intelligibility. Interference signals for three phone technologies were generated at five sound pressure levels (35 dB, 45 dB, 55 dB, 65 dB, and 75 dB) and mixed with speech at 65 dB SPL to test the speech intelligibility of 24 hearing-impaired people. A “No Noise” condition was also tested. Scores for the TDMA-217 Hz phone signal at low speech-to-noise ratios (<10 dB) were significantly lower than those for CDMA and TDMA-50 Hz at the same level. The CDMA and TDMA-50 Hz phone signals had a similar effect on speech intelligibility. Speech intelligibility scores at speech-to-noise ratios of 20 dB and 30 dB were similar to those for the “No Noise” condition. The articulation index represented the best index for predicting the impact of wireless phone interference on speech intelligibility.

The purpose of this research is to examine teachers’ capacities and the role trust plays in the professional lives of teachers during the transition to a new team of three administrators in an elementary school located in a low-income urban community in the United States. Twenty-seven teachers’ surveys and interviews showed that the transition caused some level of instability and uncertainty; however, teachers had a positive sense of efficacy, social capital, resilience, and emotions. The four themes that emerged from the interviews—common goals and vision for students, beliefs in colleagues’ competence, emotional safety and comfort, and being vulnerable with colleagues—appear to function as conditions to build trust among colleagues. The trusting relationships seem to help teachers withstand the challenging transition by providing a safe space where teachers can learn and grow. Implications for school administrators and district offices were discussed.

We introduce the concept "organizationally dependent" community to describe communities that lack the basis for developing attachment through informal social integration and in which the primary source of attachment is participation in formal organizations created to protect the community from outside threats. Neighborhoods experiencing residential renovation are examples of organizationally dependent communities. Because renovators are newcomers to their neighborhoods they cannot rely on informal social networks to solve neighborhood problems, but they can become involved in formal organizations to do so. This type of participation becomes an important source of neighborhood attachment. Data testing this hypothesis, generally, are consistent with it.

The analysis draws on Craig's framework for analyzing news coverage of ethics; on Christians, Ferre, and Fackler's communitarian ethic; and on Gilligan's relationship-oriented ethic of care. Cases from news stories illustrate the ethical complexity of anecdote use. This study suggests how journalists can choose anecdotes more critically and points to an adaptation of the anecdotal form that is ethically supportable.

On April 6, 1939, FBI agents shot and killed America’s “Public Enemy Number One” as he exited a St. Louis hamburger shop. Agents on the scene claimed the man, Ben Dickson, refused to surrender and threatened agents with two guns he carried. FBI documents and witness accounts, however, show that Dickson was shot in the back as he tried to run away from agents. Confronted by critics in the news media who questioned the legitimacy of the shooting, FBI officials in Washington worked with agents on the scene to concoct a version of events more amenable to the heroic media portrayals they preferred. Using FBI files released under the Freedom of Information Act and media accounts, this study explores the bureau’s behind-the-scenes work to legitimize the shooting and its use of the revised version of events as a public relations device demonstrating the bureau’s responsibility and utility.

Author Summary Light perception is critically important for the fitness of plants in both natural and agricultural settings. Plants not only use light for photosynthesis, but also as a cue for proper development. As a seedling emerges from soil it must determine the light environment and adopt an appropriate growth habit. When blue and red wavelengths are the dominant sources of light, plants will undergo photomorphogenesis. Photomorphogenesis describes a number of developmental responses initiated by light in a seedling, and includes shortened stems and establishing the ability to photosynthesize. The genes regulating photomorphogenesis have been studied extensively, but a complete picture remains elusive. Here we describe the finding that NUCLEAR FACTOR-Y (NF-Y) genes are positive regulators of photomorphogenesis—i.e., in plants where NF-Y genes are mutated, they display some characteristics of dark grown plants, even though they are in the light. Our data suggests that the roles of NF-Y genes in light perception do not fit in easily with those of other described pathways. Thus, studying these genes promises to help develop a more complete picture of how light drives plant development.

The three-dimensional (3D) tumor spheroid model is a critical tool for high-throughput ovarian cancer research and anticancer drug development in vitro. However, the 3D structure prevents high-resolution imaging of the inner side of the spheroids. We aim to visualize and characterize 3D morphological and physiological information of the contact multicellular ovarian tumor spheroids growing over time. We intend to further evaluate the distinctive evolutions of the tumor spheroid and necrotic tissue volumes in different cell numbers and determine the most appropriate mathematical model for fitting the growth of tumor spheroids and necrotic tissues. A label-free and noninvasive swept-source optical coherence tomography (SS-OCT) imaging platform was applied to obtain two-dimensional (2D) and 3D morphologies of ovarian tumor spheroids over 18 days. Ovarian tumor spheroids of two different initial cell numbers (5,000- and 50,000- cells) were cultured and imaged (each day) over the time of growth in 18 days. Four mathematical models (Exponential-Linear, Gompertz, logistic, and Boltzmann) were employed to describe the growth kinetics of the tumor spheroids volume and necrotic tissues. Ovarian tumor spheroids have different growth curves with different initial cell numbers and their growths contain different stages with various growth rates over 18 days. The volumes of 50,000-cells spheroids and the corresponding necrotic tissues are larger than that of the 5,000-cells spheroids. The formation of necrotic tissue in 5,000-cells numbers is slower than that in the 50,000-cells ones. Moreover, the Boltzmann model exhibits the best fitting performance for the growth of tumor spheroids and necrotic tissues. Optical coherence tomography (OCT) can serve as a promising imaging modality to visualize and characterize morphological and physiological features of multicellular ovarian tumor spheroids. The Boltzmann model integrating with 3D OCT data of ovarian tumor spheroids provides great potential for high-throughput cancer research in vitro and aiding in drug development.

Fifteen strains of an anaerobic, catalase-negative, gram-positive diphtheroid-shaped bacterium recovered from human sources were characterized by phenotypic and molecular chemical and molecular genetic methods. The unidentified bacterium showed some resemblance to Actinomyces species and related taxa, but biochemical testing, polyacrylamide gel electrophoresis analysis of whole-cell proteins, and amplified 16S ribosomal DNA restriction analysis indicated the strains were distinct from all currently named Actinomyces species and related taxa. Comparative 16S rRNA gene sequencing studies showed that the bacterium represents a hitherto-unknown phylogenetic line that is related to but distinct from Actinomyces, Actinobaculum, Arcanobacterium, and Mobiluncus. We propose, on the basis of phenotypic and phylogenetic evidence, that the unknown bacterium from human clinical specimens should be classified as a new genus and species, Varibaculum cambriensis gen. nov., sp. nov. The type strain of Varibaculum cambriensis sp. nov. is CCUG 44998T = CIP 107344T.

Due to environmental persistence and biotoxicity of polybrominated diphenyl ethers (PBDEs), it is urgent to develop potential technologies to remediate PBDEs. Introducing electrodes for microbial electricity generation to stimulate the anaerobic degradation of organic pollutants is highly promising for bioremediation. However, it is still not clear whether the degradation of PBDEs could be promoted by this strategy. In this study, we hypothesized that the degradation of PBDEs (e.g., BDE-209) would be enhanced under microbial electricity generation condition. The functional compositions and structures of microbial communities in closed-circuit microbial fuel cell (c-MFC) and open-circuit microbial fuel cell (o-MFC) systems for BDE-209 degradation were detected by a comprehensive functional gene array, GeoChip 4.0, and linked with PBDE degradations. The results indicated that distinctly different microbial community structures were formed between c-MFCs and o-MFCs, and that lower concentrations of BDE-209 and the resulting lower brominated PBDE products were detected in c-MFCs after 70-day performance. The diversity and abundance of a variety of functional genes in c-MFCs were significantly higher than those in o-MFCs. Most genes involved in chlorinated solvent reductive dechlorination, hydroxylation, methoxylation and aromatic hydrocarbon degradation were highly enriched in c-MFCs and significantly positively correlated with the removal of PBDEs. Various other microbial functional genes for carbon, nitrogen, phosphorus and sulfur cycling, as well as energy transformation process, were also significantly increased in c-MFCs. Together, these results suggest that PBDE degradation could be enhanced by introducing the electrodes for microbial electricity generation and by specifically stimulating microbial functional genes.

This follow-up study examines whether or not findings of single institution studies are applicable to other institutions by performing an institution-to-institution comparison of the results obtained from an information-seeking behavior survey sent to education faculty at twenty research institutions. The results from this study corroborated what was found in the previous study conducted on the information-seeking behavior of engineering faculty in 2009. It indicates that general information about information-seeking behavior of faculty holds true across institutions, while information related to specific library services or facilities should be validated locally.

This message-production experiment demonstrates workers’ tendency to use organizational policy justifications when publicly denying what they privately believe are unethical requests. Working adults (N = 234) responded to an unethical request from a supervisor, coworker, or subordinate. Participants avoided using explicitly moralized justifications for their noncompliance publicly and thus engaged in issue crafting. Specifically, content and statistical analyses revealed that (a) most participants invoked policy justifications to deny requests and (b) differences in hierarchical relationships were not significantly associated with policy justification frequency. These dynamics afford important face-saving functions but hold implications for the moral learning capacity of organizations. The essay concludes with implications for crafting organizational ethics policy.

The crystal structure of AdhP, a recombinantly expressed alcohol dehydrogenase
from Escherichia coli K-12 (substrain MG1655), was determined to
2.01 angstroms resolution. The structure, which was solved using molecular replacement, also included the structural and catalytic zinc ions and the cofactor nicotinamide adenine dinucleotide (NAD). The crystals belonged to space group P21, with unit-cell parameters a = 68.18, b = 118.92, c = 97.87 angstroms, beta = 106.41 degrees. The final R-factor and R-free were 0.138 and 0.184, respectively. The structure of the active site of AdhP suggested a number of residues that may participate in a proton relay, and the overall structure of AdhP, including the coordination to structural and active-site zinc ions, is similar to those of other tetrameric alcohol dehydrogenase enzymes.

Author Summary Nuclear receptors are proteins that regulate gene expression in response to steroid and thyroid hormones and other small lipid-soluble signaling molecules. In many cases, nuclear receptor genes encode multiple variants (isoforms) that direct tissue- and stage-specific hormonal responses. The sequence differences among isoforms are often found at the protein N-terminus, which mediates hormone-independent interactions with unknown regulatory partners to control target gene expression. Here, we show that the fruit fly Cryptocephal (CRC) protein is a specific coactivator for one of three isoforms of the receptor for the insect molting steroid, ecdysone. Our findings reveal a mechanism for differential activation of gene expression in response to ecdysone during insect molting and metamorphosis, and contribute to our understanding of isoform-specific functions of nuclear hormone receptors.

In the last 20 years, multiple media NGOs in Ukraine have been actively protecting the freedom of speech in the country with help of many Western donors who supported the development of its independent media system. Through systematic funding efforts and multiple programs, Western donors helped to inspire, encourage, and instill values, qualities, and attributes of the independent media among Ukrainian journalists. Western donors funded the establishment of new independent media outlets and media-related organizations in Ukraine to support freedom of speech in the country and to establish a solid network of media NGOs to monitor, report, and publicly announce any freedom of speech violations. This study investigates whether media or media NGOs in Ukraine became the most effective opinion makers in convincing Western donors to support them throughout the years. This study reports the results of the 38 interviews with representatives of Western donors and local media NGOs. The results demonstrated that Western donor support has been influential in the establishment and the development of the vast majority of media monitoring organizations, media and journalist training organizations, media NGOs and, to a lesser extent, actual independent media outlets in Ukraine. Based on the results of this study, the paper demonstrates that the media NGOs in Ukraine were actual opinion makers in regard to the status of freedom of speech in Ukraine, not the media outlets. The study discusses challenges and opportunities that Ukrainian media NGOs face as they continue to grow their presence in Ukraine. The study discusses which strategies of these NGOs as opinion makers are perceived as most sustainable and most effective by the Western donors. The paper concludes with practical implications and recommendations to media-related NGOs that operate in Ukraine, as well as other young democracies and countries in transition.

Previous studies of work/family linkages have emphasized the effects of one domain or the other on the individual, yet few have sought to analyze the interconnective nature of paid labor and family environments. Using data from the 1988 National Survey of Families and Households, this study examines the effects of husbands' and wives' employment and marriage characteristics on their respective perceptions of marital quality. Contrary to previous findings, occupational factors have only a minimal effect on both husbands' and wives' perceptions of marital quality. Husbands and wives are both affected by wives' opinions of fairness in the marriage. The results also suggest that husbands may maintain traditional role expectations for themselves and their wives, despite the dual-earner status of their marriage. The implications of these findings for gender roles in dual-earner marriages are discussed.

Drawing on research with Chickasaw citizens committed to Chikashshanompa’ (Chickasaw language) reclamation work, this chapter focuses on how Chikashshanompa’ learners and teachers engage in nation-building as they work to ensure the continuance of Chikashshanompa’ for future generations. Complementing Michelle Cooke’s chapter about teaching university Chickasaw language courses, I draw upon findings of 5 years of research during 2010–2015 with Chickasaws committed to learning, teaching, and actively using Chikashshanompa’. Together, we dedicate our chapters to the life’s work of Jerry Imotichey (1938–2016)—Michelle’s co-instructor and a language teacher to both of us. Jerry passed on in 2016, having inspired many with his love for his first language and passion for teaching others.

We analyze, through molecular dynamics simulations, the temperature dependence of the thermal conductivity (k) of chain-oriented amorphous polyethylene (PE). We find that at increasing levels of orientation, the temperature corresponding to a peak k progressively decreases. Un-oriented PE exhibits the peak k at 350K, while aligned PE under an applied strain of 400% shows a maximum at 100K. This transition of peak k to lower temperatures with increasing alignment is explained in terms of a crossover from disorder to anharmonicity dominated phonon transport in aligned polymers. Evidence for this crossover is achieved by manipulating the disorder in the polymer structure and studying the resulting change in temperature corresponding to peak k. Disorder is modified through a change in the dihedral parameters of the potential function, allowing a change in the relative fraction of trans and gauche transformations. The results shed light on the underlying thermal transport processes in aligned polymers and hold importance for low temperature applications of polymer materials in thermal management technologies.

We synthesize the interdisciplinary literature into a heuristic for crafting effective organizational and supervisory apologies (the OOPS four-component apology). In the first experiment, we demonstrate how an offense committed by an organization is perceived to be more egregious than an offense committed by a friend or supervisor. Furthermore, results did not support that OOPS apologies are unequally effective if issued by a friend, supervisor, or organization. In the second experiment, we test OOPS apology-training effectiveness. Results indicated that trained participants crafted more effective apologies. Our apology heuristic is an innovation for training business communicators how to apologize effectively.

The purpose of the present investigation was to evaluate differences in Reactive Strength Index Modified (RSIMod) and Flight Time to Contraction Time Ratio (FT:CT) during the countermovement jump (CMJ) performed without the arm swing (CMJNAS) compared to the CMJ with the arm swing (CMJAS), while exploring the relationship within each variable between jump protocols. A secondary purpose sought to explore the relationship between RSIMod and FT:CT during both jump protocols. Twenty-two collegiate basketball players performed both three CMJNAS and three CMJAS on a force plate, during two separate testing sessions. RSIMod was calculated by the flight-time (RSIModFT) and impulse-momentum methods (RSIModIMP). CMJ variables were significantly greater during the CMJAS compared to CMJNAS (p < 0.001). There were large to very large correlations within each variable between the CMJAS and CMJNAS. There were significant positive correlations among RSIModFT, RSIModIMP, and FT:CT during both the CMJAS (r ≥ 0.864, p < 0.001) and CMJNAS (r ≥ 0.960, p < 0.001). These findings identify an increase in RSIMod or FT:CT during the CMJAS, that may provide independent information from the CMJNAS. In addition, either RSIMod or FT:CT may be utilized to monitor changes in performance, but simultaneous inclusion may be unnecessary.

Associations play a powerful role in socializing practitioners. The presence of public relations associations across the world is one more step toward professionalization for the entire profession. This study examines the structure of global public relations professionalization manifested through the networks among international and national public relations professional associations. The findings of a cross-national, multilevel network analysis suggest that despite the overall dominance of international public relations associations, at the regional level, local centers have also emerged. In addition, European public relations associations have developed more relationships with other national, regional, and international associations than American-based professional associations.

Standards-based assessments were prescribed as the cure for the poor accountability of public schools. Billions of dollars have been spent on curricula, tests, and scoring rubrics so that federal and state agencies can rank schools in terms of student achievement. Over the past twenty years, standards-based education has become the de facto, only accepted method to address questions of quality in American public education. No other paradigm is even on the horizon. Despite its pandemic acceptance, the standards-based solution has serious iatrogenic consequences. This article examines five negative side effects: (1) Propagation of a fixed curriculum; (2) De-emphasis on individualization; (3) Subversion of the teacher; (4) Focus on measurable outcomes; and (5) Development of an expensive, expansive bureaucracy unrelated to instruction. The author argues that, while standards-based education may address the question of accountability, its corresponding iatrogenic consequences have been devastating in its bureaucratic intrusion on the sanctity of the classroom and representing an edict against individualization.

Empirical and anecdotal evidence shows that the news media are male-dominated. This study updates the extant literature on women’s representation in the op-ed pages of ten U.S. newspapers. A content analysis showed that female authors are moving beyond topics traditionally linked to females and are writing columns on topics such as politics and economy. However, they remain a minority, and, thus, women’s voices have yet to gain more visibility in the world of opinion writing in U.S. journalism.

In this study, I examined interpreters' self-perceived roles and their corresponding communicative goals and strategies. Twenty-six professional interpreters (of 17 languages), 4 patients, and 12 health care providers were recruited for this study, which involved participant observation of medical encounters and in-depth interviews. Constant comparative analysis was used to generate a typology of interpreters' self-perceived roles, which are different from the roles they learned in their training. Different roles reflect differences in interpreters' concern for other participants' goals, institutional goals, and their own communicative goals. Interpreters' desire to maintain neutrality during the medical encounters influences the communicative strategies they adopt when assuming other roles. I conclude the article with the theoretical and practical implications of interpreters' self-perceived roles.

Three attitude dimensions are apparent among zoological managers. They concern professional ethics, organization, and responsibility toward animals. In this article, four models of the acceptance of professional norms are tested, and career-related goals are found to be the best predictors of such attitudes. Noneconomic goals seem to promote zoological professionalism, whereas entrepreneurial activities reduce support for generally accepted norms of behavior. The implications of these findings and possibilities for further research are discussed.

Smith, Vogel, Madon, and Edwards’ (2011) recent article tested dyadic power theory (DPT) by examining the use of touch as a compliance-gaining tactic in the conflicts of married couples. In this response, we raise a methodological issue about the touch behaviors examined by Smith et al. and also pose a theoretical critique that their test of DPT violates an important scope condition of the theory. They did not examine differences between power-equal and power-unequal dyads, but instead they state that topic selection provides an actor with legitimate authority (and thus greater perceived power) and therefore the actor would touch their partner more to influence the partner. In contrast, DPT predicts that actors will use control attempts such as touch more when they are equal in power than when they are unequal. We believe DPT is relevant to touch in marital conflicts and provide a preliminary statement of that idea.

High-speed processing is essential to achieve lower production cost in the fabrication of fiber-reinforced composites with the current liquid molding practices. A major consequence of increasing the resin injection velocity is the formation of defects such as voids and dry regions that decrease the load-bearing capability of the composite. Void formation mechanisms and analytical predictions of the detrimental effect of porosity on the structural integrity of molded parts have been studied extensively. In contrast, knowledge of void removal strategies is very limited. In this investigation, various postfill pressure levels were applied to disk-shaped random-mat glass/epoxy parts molded at high volumetric flow rates as a method to reduce their voidage content. Quantitative image analysis over cross-sections cut from these composites revealed that significant changes in porosity concentration take place with the postfill pressure. For instance, overall void content dropped more than 70% with the application of a postfill pressure as low as 300 kPa. Other important void morphometry characteristics such as void shape, size, and spatial distribution could also be manipulated by this method. As the packing pressure increases, large voids gradually disappear, and at the same time, the small circular voids are mobilized towards radial locations near the vents. In addition to this spatial voidage gradient in the radial direction, voidage gradient also exists through the specimen thickness. It seems that higher front velocities promote the appearance of secondary flow phenomena inside the mold cavity (e.g. microfountain flow), which may explain why more voids tend to concentrate at the surface of the specimen irrespective of the postfill pressure level reached inside the mold.

This article addresses the relationship between two related behavioral domains in adolescents: sexual activity and mildly deviant behavior (defined as behaviors of which parents would disapprove, but which are not illegal). Previous work has demonstrated overlap between these behavioral domains. We use a unique data set - the data from the Carolina Population Center's Adolescent Sexuality (ADSEX) Project which contain linkable responses of siblings, best friends, and other friends - to quantify the degree of overlap and separation between sexuality and mild deviance. We cast our work in a conceptual context identifying the prominent members of a respondent's environment, including siblings, same-sex friends (best friends and other friends) and opposite-sex friends (best and other friends). Results support previous research showing overlap between sexuality and mild deviance; however, the two domains are also distinguishable. Furthermore, theoretical predictions generated by the conceptual framework - by considering the relationship of adolescents to others in their environment - are supported by the data.

This paper places broadcast major party convention ratings in the broader context of the changing media environment from 1976 until 2008 in order to explore the decline in audience for the convention. Broadcast convention ratings are contrasted with convention ratings for cable news networks, ratings for broadcast entertainment programming, and ratings for “event” programming. Relative to audiences for other kinds of programming, convention audiences remain large, suggesting that profit-making criteria may have distorted representations of the convention audience and views of whether airing the convention remains worthwhile.

A number of authorities on management education believe that those who teach management should have managerial experience or have been in contact with real-world management practices. However, a significant number of management professors have had only minimal management experience. The authors make the case that this may be problematic. This shortcoming has an effect on the quality of the product we are providing to the business world. There is a need for a rethinking of the relationship between academia and practicing managers. A number of strategies that will help to remedy the shortcomings associated with the minimal managerial experience of management professors are offered.

Results from two experiments suggest that stereotype-threat effects are special cases of a more general process involving the need to maintain or enhance status. We hypothesized that situations capable of confirming a performance stereotype might represent either a threat to status or an opportunity for enhancement of status, depending on the nature of the stereotype. The positive relationship between baseline testosterone and status sensitivity led us to hypothesize that high testosterone levels in males and females would amplify existing performance expectations when gender-based math-performance stereotypes were activated. In Study 1, high-testosterone females performed poorly on a math test when a negative performance stereotype was primed. In Study 2, high-testosterone males excelled on a math test when a positive performance stereotype was primed. The moderating effect of testosterone on performance suggests that a stereotype-relevant situation is capable of conferring either a loss or a gain of status on targets of the stereotype.

A necessary element to design and produce customer-centric products is the integration of customers in the design process. Challenges faced during customer integration into the design process include generating models of the customized product, performing analysis of these to determine feasibility, and optimizing to increase the performance. These tasks have to be performed relatively quickly, if not in real time, to provide feedback to the customer. The focus of this article is to present a framework that utilizes CAD, finite element analysis (FEA), and optimization to integrate the customer into the design process via the Internet for delivering user customized products. The design analysis, evaluation, and optimization need to be automated and enhanced to enable operation over the Internet. A product family CAD/FEA template has been developed to perform analysis, along with a general formulation to optimize the customized product. The CAD/FEA template generalizes the geometry building and analysis of each configuration developed using a product platform approach. The proposed setup is demonstrated through the use of a bicycle frame family. In this study, the focus is on the application of optimization and FEA to facilitate the design of customer-centric products.

Cultural astronomy is the study of the astronomy of ancient cultures and is sometimes called the anthropology of astronomy. The many ways that astronomy was used by ancient cultures are fascinating and this can be used to inspire interest in all astronomy, as well as astronomy in culture. Archaeoastronomy is interdisciplinary and among its practitioners are not only astronomers and astrophysicists, but also anthropologists, archaeologists, and Indigenous scholars. Much can be learned about ancient cultures though examination of how and why they used astronomy. This paper will highlight several examples that can capture public attention.

We are rapidly advancing toward an understanding of the molecular events underlying odor transduction, mechanisms of spatiotemporal central odor processing, and neural correlates of olfactory perception and cognition. A thread running through each of these broad components that define olfaction appears to be their dynamic nature. How odors are processed, at both the behavioral and neural level, is heavily dependent on past experience, current environmental context, and internal state. The neural plasticity that allows this dynamic processing is expressed nearly ubiquitously in the olfactory pathway, from olfactory receptor neurons to the higher-order cortex, and includes mechanisms ranging from changes in membrane excitability to changes in synaptic efficacy to neurogenesis and apoptosis. This review will describe recent findings regarding plasticity in the mammalian olfactory system that are believed to have general relevance for understanding the neurobiology of memory.

The relative significance of 11 environmental factors on the apparent steady-state concentration of hydrogen (ASSCH2) achieved during anaerobic degradation of refuse collected from landfills was evaluated by using multiple regression analysis. Simple correlation analysis revealed a significant negative association of ASSCH2 with newsprint moisture content (NMO) and pH of the sample. Application of five different variable selection procedures, which are commonly used in multiple regression analyses, showed that NMO, amylase (AMY), esterase (EST), cellulose to lignin ratio (CLR), volatile solids (VS), and nitrogen content (NIT) were significantly associated with ASSCH2 simultaneously. The other five factors did not show any significant effect on ASSCH 2 in the presence of the six significant factors. Further analysis showed that the influence of AMY and EST on ASSCH2 was weak, hence they were not included in the regression model. CLR was also deleted from the final model because of the multicollinearity resulting from its high correlation with VS. The final model incorporated NMO, NMO2, VS2 and NIT2; it explained 95% of the total variability and predicted 98% of the observed ASSCH2. An assessment of the relative significance of the independent variables indicated that NMO contributed the most, followed by NMO2 and VS2, in that order, and the least by NIT2 towards ASSCH2. The NMO and NIT 2 showed an inhibitory effect on ASSCH2. The results indicated that maintaining optimum moisture, along with optimum organic loading, and nitrogen content in landfills is necessary to achieve and maintain a low ASSCH2 and maximize refuse methanogenesis.

ABSTRACT:
At small scales, storage is straightforward to afford and to use, but at large scales – from several Terabytes (TB) to many Petabytes (PB) and soon Exabytes (EB) – tradeoffs must be made between cost and convenience, and training for use of such resources needs to take such inconveniences into account. A large scale, long term (over 10 year) institutional research data storage archive is described, focusing onboth hardware and software. The technology choices give rise to inconveniences, which in turn not only lead to a crucial requirement for training on the proper use of the archive, but also inform the specifics of that training, as does each individual use case.

Cultural anthropologist Misha Klein reflects on a Jewish Studies course, entitled Anthropology of Jews and Jewishness, taught at the University of Oklahoma. The recent explosion of interest in the anthropological study of Jews and Jewish cultures has occurred in large part because of the ways Jews provide a lens through which to examine core concepts and concerns within anthropology. As Klein conceives it, the course is an exploration of these core issues, including race, ethnicity, identity, kinship, migra- tion, diaspora and transnationalism, gender and sexuality, religion and ritual, foodways, language, national identity, and globalization. A sample syllabus is provided.

Author Summary Soil-transmitted helminth (STH) infections with A. lumbricoides, T. trichiura and hookworms are endemic in all 80 provinces of the Philippines, but the spatial variation in the prevalence of these infections has not been previously described. This analysis revealed that while A. lumbricoides and T. trichiura infections were widespread and highly endemic, hookworm infections were more circumscribed to smaller foci in the Visayas and Mindanao. The results also suggest that it may be necessary to place greater emphasis on improving the provision of water, sanitation and the promotion of behavioral change for improved hygiene for the control and prevention of STH infections, particularly for hookworm.

Richard Fenno, in Power of the Purse, contends that the budget process responds to interest group pressures. This study examines that hypothesis for 20 bureaus in the Department of Agriculture for the fiscal years 1971-1976. Cultivating clientele support both among interest groups and members of Congress appears to aid a bureau's budget position. Bureaus with strong support not only avoid budget cuts but grow rapidly from year to year.

The efficacy of the urban regime and growth machine concepts beyond the US remains a matter of considerable debate. Some argue that these frameworks retain considerable value so long as they are 'properly' applied and that recent concerns about the limits to these frameworks result from no more than their 'misapplication'. I critically examine this argument through a review of recent work on the mobilisation of business interests in British cities. The central claim is that, even when focused on the 'right' issues and questions, US frameworks quickly exhaust their explanatory capacity. In the context of a widening diversity of alternative approaches, I suggest that it is time to move squarely beyond growth coalition and regime accounts. The paper makes a number of suggestions for ways in which this new phase of theory building might proceed.

The detection of environmental violators is critical to the long-term adoption of sustainability in supply chain management. However, there exist manufacturing facilities that report false environmental monitoring data, thereby seriously hampering governments’ efforts to identify true offenders and to properly intervene. We integrate waste gas data from the world’s largest Continuous Emission Monitoring System (CEMS) with a publicly available Violation and Punishment Dataset (VPD) to build prediction models for the identification of environmental violators. We utilize and create innovative machine learning approaches to overcome analytical challenges associated with empirical data. First, we use a feature engineering approach to generate features from the raw, and possibly fraudulent, reporting data. This overcomes the challenges associated with low fidelity, irregularity, and the presence of extreme values in the raw dataset. Second, while building prediction models, we develop new approaches to positive and unlabeled learning to overcome the challenges posed by sparsity and mislabeled data. Our prediction model achieves satisfactory results in a related field test. Our study develops new techniques for big data analytics, which greatly improve the efficiency and effectiveness in detection of environmental violators and enhance operational outcomes of environmental protection agencies. This research is a joint effort between academia and practitioners, as evidenced by the participation of the Ministry of Ecology and Environment of People’s Republic of China. The Ministry kindly granted us direct data access, as well as opportunities to interview Subject Matter Experts at the Ministry, which led to research insights incorporated in this manuscript. Our research findings have global implications, as CEMS devices are universally adopted to monitor waste gas emissions. This is a postprint of the published article.

In this article, we wrestle with the core issue of how early career researchers translate central tenets and core concepts of critical theory and critical methodology into their research practice. By way of creative representation, we draw from bell hooks and Cornel West’s (1991) written rendition of their verbal dialogue in Breaking Bread: Insurgent Black Intellectual Life. Their hope was to offer the book in a dialogic format in such a way that mirrored the synergy in their verbal discussions as friends and intellectual colleagues. In a similar vein, we hope to share with readers the synergy and depth of the narratives that have transpired during our ongoing discussions on the important topic of critical praxis as part of a collaborative research group called the Disruptive Dialogue Project (Gildersleeve, Kuntz, Pasque & Carducci, 2010; Kuntz, Pasque, Carducci, & Gildersleeve, 2009).

This study investigates the theory/applications orientation in management courses, the factors which influence this balance, and the techniques used to bring applications into the classroom. Overall, the findings indicate a balance between theory and applications. However, the theory/applications orientation was influenced by a number of factors: the subject matter, the level of instruction, the age, rank, and managerial experience of the instructor, and the size of the institution. Substantial differences were found between graduate and undergraduate levels of instruction.

Students with learning disabilities (LD) often need to be taught self-determination skills to be better prepared for life after high school. This article describes the methods used by one school district to promote self-advocacy and self-awareness skills for students with LD. Through multicomponent group activities, students learned about their strengths and disabilities and how to advocate for their educational needs and rights. Advocacy skills were also applied to leadership roles, mentoring, and community education activities. Important features that contributed to the success of the program are described.

Granville Stanley Hall, founder of the American Psychological Association and president of Clark University, was the first American psychologist to speak and write about music's place in the educational curriculum. An examination of his published writings reveals Hall based his theory of music education on principles of Social Darwinism and Child Study perspectives on education. Hall's theories are referenced and paraphrased in several song series textbooks and music appreciation texts published by music educators during his professional career. These sources indicate that Hall influenced the thinking of certain music educators and was important to music education, in general, in developing a receptivity toward psychological processes in music education practice.

Using a modification of the Barrnett and Seligman histochemical procedure, the proportion of protein-bound S—S/SH Was measured in the chromatin of onion root tip cells at three different stages of mitosis as well as in the nucleolus. Inconsistencies between experiments led to studies of the nature of the histochemical reaction before and after sections were reduced in thioglycolate. Different fixatives and ribonuclease were tested for their effects on the outcome of the reaction.

The design of a connected engineered system requires numerous design decisions that influence one another. In a connected system that comprises numerous interacting decisions involving concurrency and hierarchy, accounting for interactions while also managing uncertainties, it is imperative to make robust decisions. In this article, we present a method for robust design using coupled decisions to identify design decisions that are relatively insensitive to uncertainties. To account for the influence among decisions, design decisions are modelled as coupled decisions. They are defined using three criteria: the types of decisions, the strength of interactions and the decision levels. In order to make robust decisions, robust design methods are classified based on sources of uncertainty, namely, Type I (noise factors), Type II (design variables) and Type III (function relationship between design variables and responses). The design of a one-stage reduction gearbox is used as a demonstration example. To illustrate the proposed method for robust design using coupled decisions, we present the simultaneous selection of gear material and gearbox geometry in a coupled decision environment while managing the uncertainties involved in designing gearboxes.

Hiring freezes are a common strategy that organizations pursue during times of fiscal austerity to conserve funds. While a freeze does impact an organization, the impact is certainly less than a layoff would be. Hiring freezes, after all, are designed to be temporary, but layoffs are a permanent workforce reduction. Interim leaders may believe they have less ability to successfully address hiring freezes than those holding permanent appointments, but in reality they likely have resources at their disposal to be just as successful as other organizational leaders during such times. In this chapter, librarians will learn strategies they can employ before, during, and after a hiring freeze to speed the filling of positions when a freeze is anticipated; to make the best use of time and other resources during the freeze; and to position their organization to move creatively and effectively in filling positions when the freeze is lifted.

The atmosphere is populated by a diverse array of dispersing insects and their predators. We studied aerial insect communities by tracking the foraging altitudes of an avian insectivore, the Purple Martin (Progne subis). By attaching altitude loggers to nesting Purple Martins and collecting prey delivered to their nestlings, we determined the flight altitudes of ants and other insects. We then tested hypotheses relating ant body size and reproductive ecology to flight altitude. Purple Martins flew up to 1,889 meters above ground, and nestling provisioning trips ranged up to 922 meters. Insect communities were structured by body size such that species of all sizes flew near the ground but only light insects flew to the highest altitudes. Ant maximum flight altitudes decreased by 60% from the lightest to the heaviest species. Winged sexuals of social insects (ants, honey bees, and termites) dominated the Purple Martin diet, making up 88% of prey individuals and 45% of prey biomass. By transferring energy from terrestrial to aerial food webs, mating swarms of social insects play a substantial role in aerial ecosystems. Although we focus on Purple Martins and ants, our combined logger and diet method could be applied to a range of aerial organisms.

During the 1930s a number of interesting critiques of science and society emerged in the social sciences in general, and in psychology in particular. One example of this trend is The Psychology of Radio (1935), authored by Harvard psychologist Gordon Allport and his former student Hadley Cantril. The book, which was intended for both professional and lay audiences, sought to open discussion on the effects of the pervasive presence of radio, and to throw into relief the political, cultural, and economic contexts in which this new form of mass communication was embedded.

Promoting self-determination has been identified as best practice in special education and transition services and as a means to promote goal attainment and access to the general education curriculum for students with disabilities. There have been, however, limited evaluations of the effects of interventions to promote self-determination on outcomes related to access to the general education curriculum. This article reports findings from a cluster or group-randomized trial control group study examining the impact of intervention using the Self-Determined Learning Model of Instruction on students’ academic and transition goal attainment and on access to the general education curriculum for students with intellectual disability and learning disabilities. Findings support the efficacy of the model for both goal attainment and access to the general education curriculum, though students varied in the patterns of goal attainment as a function of type of disability.

The purpose of this study was to evaluate instructional activities and practice techniques of musicians attempting to improve their accuracy in detecting errors in music examples heard. In this study, a commonly recommended practice procedure, keyboard sight-reading, was compared with listening to recorded examples of simple piano works characteristic of those used in college-level class piano courses. The authors randomly assigned 59 college music majors to two groups. One group (Group R) studied examples by sight-reading music excerpts at the keyboard; the other group (Group L) studied the same excerpts by listening to recordings. Both groups were tested using taped examples of the excerpts with harmonic alterations. When data were collected for harmonic alterations not detected (misses) and for errors indicated where none were performed (false alarms), Group L was significantly more accurate (p = .0001) in detecting harmonic alterations than was Group R. The difference between the two groups was the same regarding false alarms (p = .0001). A repeated measures design was employed 2 weeks later with similar results. The data also indicated a possible effect of treatment order (listening first or sight-reading first). Implications are drawn for classroom application and for further study.

Thermo-mechanical properties of polymers can be significantly altered by the addition of nano-scale particulates such as carbon nanotubes and nanofibers. Among the nano-scale particulates, inclusion of nanoclay is proven to improve thermal and mechanical properties of polymers significantly even at small volume fraction levels. In addition, nanoclay is a viable commercial alternative to conventional fillers owing to its low-cost and accessibility. However, akin to various particulates, extensive agglomeration of nanoclay in polymer matrices presents difficulties in its utilization.
In this study, we implement a multi-scale approach to characterize the dispersion of three different types of nanoclays. Cloisite® 15A, 25A and 30B are individually mixed with Epon 815C epoxy resin, by the aid of a sonicator. The resin/nanoclay compound is then mixed with Epi-cure 3282 curing agent and injected into center-gated disk shaped molds. The dispersion state of nanoclay is characterized by using samples cut along the radius of the molded composite disks. Nanoclay clusters larger than 1.5µm are characterized by performing digital image analysis on the scanning electron micrographs, whereas smaller clusters are identified by wavelength dispersive spectrometry. In addition, intra-cluster structure is studied by transmission electron microscopy.
It is found that the effectiveness of dispersion increases in the order of Cloisite® 15A, 25A and 30B. For instance the average content of clusters larger than 1.5µm is determined as 4.6vol.% for Cloisite® 15A, whereas the same value for 25A and 30B are 3.39vol.% and 3.45vol.%, respectively. The nanoclay clusters are observed to break down into smaller pieces in the flow direction, regardless of the nanoclay type. For example, small Cloisite® 30B clusters (Area<3µm2) make up 37.8% of the nanoclay content at the inlet, whereas the same value is calculated to be 46% at the outer edge of the disk. Several nano-voids are detected in the intra-cluster regions from the TEM images. These nano-voids are suspected to result from insufficient dispersion of nanoclay in epoxy matrix.

In response to a request for an interview to be conducted at the U.S. Naval Observatory, 73-year-old famed astronomer and retired Harvard Observatory Director, Harlow Shapley (1885–1972), stated that for the upcoming NBC interview he did not “care to pose with a telescope.” Shapley explained that apart from some episodes in his scientific youth, he had spent little time actually peering through telescopes. He wanted to make the point that like most astronomers, his contributions were based on a range of activities distinct from the practice of observing. While this 1959 exchange is instructive with respect to Shapley’s view of his astronomical work, it is also instructive with respect to Shapley’s view of his potential historical legacy. Shapley believed that some of his most important contributions lay outside science; he wanted to be seen not only as a scientist, but also as a scholar and a public intellectual. The title of his 1967 book, "Beyond the Observatory," aptly characterizes a career in which considerable effort was devoted to extending his influence beyond astronomical and scientific circles. Yet Shapley’s work beyond these circles was shaped in important ways by his career in science, and especially, by his belief that the findings of science held lessons of profound significance for humanity. Shapley achieved scientific renown through his work as an astronomer and observatory director. In these roles he influenced the course of 20th century astronomy and shaped his contemporaries’ understanding of the cosmic facts. Yet elucidating the broader and very human significance of the cosmic facts was this scientist’s true calling. Bringing the cosmos to human culture was Harlow Shapley’s lifelong mission.

Coarse-grained modeling methods allow simulations at larger scales than molecular dynamics, making it feasible to simulate multifluid systems. It is, however, critical to use model parameters that represent the fluid properties with fidelity under both equilibrium and dynamic conditions. In this work, dissipative particle dynamics (DPD) methods were used to simulate the flow of oil and water in a narrow slit under Poiseuille and Couette flow conditions. Large surfactant molecules were also included in the computations. A systematic methodology is presented to determine the DPD parameters necessary for ensuring that the boundary conditions were obeyed, that the oil and water viscosities were represented correctly, and that the velocity profile for the multifluid system agreed with the theoretical expectations. Surfactant molecules were introduced at the oil–water interface (sodium dodecylsulfate and octaethylene glycol monododecyl ether) to determine the effects of surface-active molecules on the two-phase flow. A critical shear rate was found for Poiseuille flow, beyond which the surfactants desorbed to form the interface forming micelles and destabilize the interface, and the surfactant-covered interface remained stable under Couette flow even at high shear rates.

The cultural experiences of minority learners are often omitted from the formal curriculum leading to exclusion and a sense of cultural loss. In this study, the researcher’s lived experience serves as the basis to develop a novel research strategy: transformative autoethnography. The researcher uses the method of autoethnography to more deeply understand his roles as Chickasaw and adult educator, amplified by his unique role as the developer of a tribal learning community situated at a research university. This immersive experience serves as the context for self-reflection, which includes an educational history marred by my perceptions of Whiteness and lack of cultural connectedness. Transformative learning theory serves as the theoretical framework by which the author comes to appreciate the intersection of culture, identity, and meaning. The research context is triangulated with the experiences of other Chickasaws, including learning community participants, providing an autoethnography steeped in phenomenological thought. This credible qualitative account serves as a roadmap for the educational journeys of Native Americans and other minority adult learners and the educators, advisors, and program developers who strive to support them.

The present study investigated the effects of question prompts in scaffolding novice instructional designers solving ill-structured, instructional design problems in a Web-based learning environment. The effects of question prompts were studied under different prompting conditions (Question-Elaboration vs. Question-Guidance), taking into consideration various levels of learners' prior knowledge and experience. The study employed a comparative, multiple-case study design using the technique of think-aloud protocols, which were followed by interviews. Eight graduate students from the program of Instructional Design and Technology participated in the study. While the qualitative findings supported the previous research on the advantages of question prompts in scaffolding ill-structured problem solving, they also shed light on the specific cognitive and metacognitive functions, as well as limitations, of question prompts in different conditions. The study has implications for designing instructional scaffolds for supporting ill-structured problem solving of various domains in a Web-based learning environment.

This study provides an exploratory content analysis of business continuity planning (BCP) literature. The researchers systematically sampled multiple databases and codified artifacts using a set of variables developed by the research team. Based on the analysis, arguments are presented concerning the nature of BCP, the state of the BCP literature, and the nature of the conversations taking place in regard to BCP among academics, government/legal institutions, the media, and trade industries. Finally, the researchers demonstrate gaps in the current knowledge on BCP and suggest future directions for applied and theoretical research.

Tenontosaurus tilletti is an ornithopod dinosaur known from the Early Cretaceous (Aptian-Albian) Cloverly and Antlers formations of the Western United States. It is represented by a large number of specimens spanning a number of ontogenetic stages, and these specimens have been collected across a wide geographic range (from central Montana to southern Oklahoma). Here I describe the long bone histology of T. tilletti and discuss histological variation at the individual, ontogenetic and geographic levels. The ontogenetic pattern of bone histology in T. tilletti is similar to that of other dinosaurs, reflecting extremely rapid growth early in life, and sustained rapid growth through sub-adult ontogeny. But unlike other iguanodontians, this dinosaur shows an extended multi-year period of slow growth as skeletal maturity approached. Evidence of termination of growth (e.g., an external fundamental system) is observed in only the largest individuals, although other histological signals in only slightly smaller specimens suggest a substantial slowing of growth later in life. Histological differences in the amount of remodeling and the number of lines of arrested growth varied among elements within individuals, but bone histology was conservative across sampled individuals of the species, despite known paleoenvironmental differences between the Antlers and Cloverly formations. The bone histology of T. tilletti indicates a much slower growth trajectory than observed for other iguanodontians (e.g., hadrosaurids), suggesting that those taxa reached much larger sizes than Tenontosaurus in a shorter time.

The Theory of Planned Behavior was used as a framework, along with Self-Determination Theory, to examine preservice teachers' motivation to include technology in their future teaching. We modified instruments to measure theoretical constructs to be applied to plans for the use of technology. Measured were: perceived behavioral control, attitudes toward technology use, perceived social norms, intrinsic and extrinsic motivation and amotivation. One hundred and fourteen preservice teachers completed the instrumentation and 67 completed a pre/post activity and reflective task concerning their attitudes and beliefs on technology, technology integration, and its role in the classroom. The best single predictor of both intrinsic and extrinsic motivation was positive attitudes toward technology use. For amotivation, the best predictors were negative attitudes toward technology use and negative social norms. The pre-post activity demonstrated that participants struggled to design meaningful technology integration activities.

1. Shifts in dominance and species reordering can occur in response to global change. However, it is not clear how altered precipitation and disturbance regimes interact to affect species composition and dominance.
2. We explored community‐level diversity and compositional similarity responses, both across and within years, to a manipulated precipitation gradient and annual clipping in a mixed‐grass prairie in Oklahoma, USA. We imposed seven precipitation treatments (five water exclusion levels [−20%, −40%, −60%, −80%, and −100%], water addition [+50%], and control [0% change in precipitation]) year‐round from 2016 to 2018 using fixed interception shelters. These treatments were crossed with annual clipping to mimic hay harvest.
3. We found that community‐level responses were influenced by precipitation across time. For instance, plant evenness was enhanced by extreme drought treatments, while plant richness was marginally promoted under increased precipitation.
4. Clipping promoted species gain resulting in greater richness within each experimental year. Across years, clipping effects further reduced the precipitation effects on community‐level responses (richness and evenness) at both extreme drought and added precipitation treatments.
5. Synthesis: Our results highlight the importance of studying interactive drivers of change both within versus across time. For instance, clipping attenuated community‐level responses to a gradient in precipitation, suggesting that management could buffer community‐level responses to drought. However, precipitation effects were mild and likely to accentuate over time to produce further community change.

The last step of cysteine biosynthesis in bacteria and plants is catalyzed by O-acetylserine sulfhydrylase. In bacteria, two isozymes, O-acetylserine sulfhydrylase-A and O-acetylserine sulfhydrylase-B, have been identified that share similar binding sites, although the respective specific functions are still debated. O-acetylserine sulfhydrylase plays a key role in the adaptation of bacteria to the host environment, in the defense mechanisms to oxidative stress and in antibiotic resistance. Because mammals synthesize cysteine from methionine and lack O-acetylserine sulfhydrylase, the enzyme is a potential target for antimicrobials. With this aim, we first identified potential inhibitors of the two isozymes via a ligand- and structure-based in silico screening of a subset of the ZINC library using FLAP. The binding affinities of the most promising candidates were measured in vitro on purified O-acetylserine sulfhydrylase-A and O-acetylserine sulfhydrylase-B from Salmonella typhimurium by a direct method that exploits the change in the cofactor fluorescence. Two molecules were identified with dissociation constants of 3.7 and 33 µM for O-acetylserine sulfhydrylase-A and O-acetylserine sulfhydrylase-B, respectively. Because GRID analysis of the two isoenzymes indicates the presence of a few common pharmacophoric features, cross binding titrations were carried out. It was found that the best binder for O-acetylserine sulfhydrylase-B exhibits a dissociation constant of 29 µM for O-acetylserine sulfhydrylase-A, thus displaying a limited selectivity, whereas the best binder for O-acetylserine sulfhydrylase-A exhibits a dissociation constant of 50 µM for O-acetylserine sulfhydrylase-B and is thus 8-fold selective towards the former isozyme. Therefore, isoform-specific and isoform-independent ligands allow to either selectively target the isozyme that predominantly supports bacteria during infection and long-term survival or to completely block bacterial cysteine biosynthesis.

Author Summary Humoral immunity is essential for host resistance to pathogens that trigger highly inflammatory immune responses, including Plasmodium parasites, the causative agents of malaria. Long-lived, secreted antibody responses depend on a specialized subset of CD4 T cells called T follicular helper (Tfh) cells. However, anti-Plasmodium humoral immunity is often short-lived, non-sterilizing, and immunity rapidly wanes, leaving individuals susceptible to repeated bouts of malaria. Here we explored the relationship between inflammatory type I interferons, the regulation of pathogen-specific CD4 T cell responses, and humoral immunity using models of experimental malaria and systemic virus infection. We identified that type I interferons promote the formation and accumulation of pathogen-specific CD4 T regulatory 1 cells that co-express interferon-gamma and interleukin-10. Moreover, we show that the combined activity of interferon-gamma and interleukin-10 limits the magnitude of infection-induced Tfh responses, the secretion of parasite-specific secreted antibody, and parasite control. Our study provides new insight into the regulation of T regulatory 1 responses and humoral immunity during inflammatory immune reactions against systemic infections.

Indigenous communities, organizations, and individuals work tirelessly to #KeepOurLanguagesStrong. The COVID-19 pandemic was potentially detrimental to Indigenous language revitalization (ILR) as this mostly in-person work shifted online. This article shares findings from an analysis of public social media posts, dated March through July 2020 and primarily from Canada and the US, about ILR and the COVID-19 pandemic. The research team, affiliated with the NEȾOLṈEW̱ “one mind, one people” Indigenous language research partnership at the University of Victoria, identified six key themes of social media posts concerning ILR and the pandemic, including: 1. language promotion, 2. using Indigenous languages to talk about COVID-19, 3. trainings to support ILR, 4. language education, 5. creating and sharing language resources, and 6. information about ILR and COVID-19. Enacting the principle of reciprocity in Indigenous research, part of the research process was to create a short video to share research findings back to social media. This article presents a selection of slides from the video accompanied by an in-depth analysis of the themes. Written about the pandemic, during the pandemic, this article seeks to offer some insights and understandings of a time during which much is uncertain. Therefore, this article does not have a formal conclusion; rather, it closes with ideas about long-term implications and future research directions that can benefit ILR.

In January 1994 the Zapatista movement in southern Mexico inaugurated a new era of media use for dissent. Since that time, an array of dissenting collectives and individuals have appropriated media technologies in order to make their voices heard or to articulate alternative identities. From Zapatista media to the Arab Spring, social movements throughout the world are taking over, hybridizing, recycling, and adapting media technologies. This new era poses a new set of challenges for academics and researchers in the field of Communication for Social Change (CfSC). Based on examples from Mexico, Lebanon, and Colombia, this article highlights and discusses four such research challenges: accounting for historical context; acknowledging the complexity of communication processes; anchoring analysis in a political economy of information and communication technologies; and positioning new research in relation to existing knowledge and literature within the field of communication and social change.

While female mate preference is very well studied, male preference has only recently begun to receive significant attention. Its existence is found in numerous taxa, but empirical research has mostly been limited to a descriptive level and does not fully address the factors influencing its evolution. We attempted to address this issue using preference functions by comparing the strength of male preference for females of different sizes in nine populations of four poeciliid species. Due to environmental constraints (water toxicity and surface versus cave habitat), females from these pop- ulations vary in the degree to which their size is correlated to their fecundity. Hence, they vary in how their size signals their quality as mates. Since female size is strongly correlated with fecundity in this subfamily, males were sequentially presented with conspecific females of three different size categories and the strength of their pref- erence for each was measured. Males preferred larger females in all populations,
as predicted. However, the degree to which males preferred each size category, as measured by association time, was not correlated with its fecundity. In addition, cave males discriminated against smaller females more than surface males. Assuming that male preference is correlated with female fitness, these results suggest that factors other than fecundity have a strong influence on female fitness in these species.

Introduction More than 80% of all smokeless tobacco (ST) products in the world are consumed in South Asia; yet little is known about their consumption behaviour, addictiveness, and toxic properties. This paper, for the first time, describes associations between salivary cotinine concentrations among ST users in Bangladesh and their socio-demographic characteristics and tobacco use behaviours. Methods In a survey of ST users in Dhaka, Bangladesh, we purposively recruited 200 adults who were non-smokers but consumed ST on a regular basis. In-person interviews were conducted to obtain information about socio-demographic and ST use behaviours, and saliva samples were collected to measure cotinine concentration. Simple and multiple linear regression analyses were conducted to test associations between the log transformed salivary cotinine concentration and other study variables. Results The geometric mean of cotinine concentration among ST users was 380ng/ml (GSD:2). Total duration of daily ST use in months had a statistically significant association with cotinine concentration. Other ST use characteristics including type and quantity of ST use, swallowing of tobacco juice, urges and strength of urges and attempts to cut down on tobacco use were not found to be associated with cotinine concentration in a multivariable model. Conclusion This is the first report from Bangladesh studying cotinine concentration among ST users and it points towards high levels of addiction. This warrants effective tobacco control policies to help ST cessation and prevention.
