Lesbian, Gay, and Transgender Persons with Severe Mental Illness: Negotiating Wellness in the Context of Multiple Sources of Stigma

The experiences of lesbian, gay, and transgender (LGT) individuals with severe mental illness (SMI) have received minimal attention within the clinical and research literatures despite evidence to suggest that these groups receive inadequate psychiatric services. In the present study, 11 individuals from a midsized Canadian city who self-identified as lesbian, gay, or transgender were interviewed about their experiences of sexual identity, gender, mental illness, and psychiatric services. Their narratives were analyzed using grounded theory methods. The findings highlight the complex interactions of the stigma associated with mental illness and LGT identities, as well as the illness and identity-related challenges these persons face in psychiatric services. The participant narratives also speak to resilience and wellness, suggesting that these are cultivated through connection and community. Finally, strategies that service providers can use to deliver more effective services for this population are discussed.
A Nonparametric Bayesian Approach to Image Compressive Sensing on Manifolds with Correlation Constraints

The broad class of manifold models are considered for extending the conventional compressive sensing (CS) to a more general framework. However, although the manifold-based CS approaches using a mixture of factor analyzers can learn latent geometric structures of high-dimensional signals, they have two issues that potentially limit their practical use: First, the manifold modeling does not take account of sharing factors among mixture components and thus misses the chance to enhance statistical strength; Second, introducing correlation constraints may cause intractable model inference. In this paper, we address these issues by: 1) depicting the mixture correlations with a hierarchical Beta process whose upper-layer process is an Indian buffet process in nonparametric Bayesian manner; 2) deriving a combination of collapsed Gibbs sampler and auxiliary-variable-based slice sampler to obtain the model accurate solutions. Experimental results on real dataset demonstrate that our proposed method provides significant performance improvements compared to the sparsity-based CS algorithms, while outperforming the state-of-the-art manifold-based inversion strategies for image reconstruction.
Retinoic Acid Leads to Cytoskeletal Rearrangement through AMPK-Rac1 and Stimulates Glucose Uptake through AMPK-p38 MAPK in Skeletal Muscle Cells*

Retinoic acid (RA) is one of the major components of vitamin A. In the present study, we found that retinoic acid activated AMP-activated protein kinase (AMPK). RA induced Rac1-GTP formation and phosphorylation of its downstream target, p21-activated kinase (PAK), whereas the inhibition of AMPK blocked RA-induced Rac1 activation. Moreover, cofilin, an actin polymerization regulator, was activated when incubated with RA. We then showed that inhibition of AMPK by compound C, a selective inhibitor of AMPK, or small interfering RNA of AMPK α1 blocked RA-induced cofilin phosphorylation. Additionally, we found that retinoic acid-stimulated glucose uptake in differentiated C2C12 myoblast cells and activated p38 mitogen-activated protein kinase (MAPK). Finally, the inhibition of AMPK and p38 MAPK blocked retinoic acid-induced glucose uptake. In summary, our results suggest that retinoic acid may have cytoskeletal roles in skeletal muscle cells via stimulation of the AMPK-Rac1-PAK-cofillin pathway and may also have beneficial roles in glucose metabolism via stimulation of the AMPK-p38 MAPK pathway.
Butterfly Mixing: Accelerating Incremental-Update Algorithms on Clusters

Incremental model-update strategies are widely used in machine learning and data mining. By “incremental update” we refer to models that are updated many times using small subsets of the training data. Two wellknown examples are stochastic gradient and MCMC. Both provide fast sequential performance and have generated many of the best-performing methods for particular problems (logistic regression, SVM, LDA etc.). But these methods are difficult to adapt to parallel or cluster settings because of the overhead of distributing model updates through the network. Updates can be locally batched to reduce communication overhead, but convergence typically suffers as the batch size increases. In this paper we introduce and analyze butterfly mixing, an approach which interleaves communication with computation. We evaluate butterfly mixing on stochastic gradient algorithms for logistic regression and SVM, on two datasets. Results show that butterfly mix steps are fast and failure-tolerant, and overall we achieved a 3.3x speedup over full mix (AllReduce) on an Amazon EC2 cluster.
The Use of Media in Constructing Identities in the Masculine Environment of Men's Prisons

This article explores the importance of media forms and content within a unique context: the prison. Although — in common with other studies of media use among prisoners — it is inspired by the uses and gratifications tradition, this study refines and develops the approach, synthesizing it with Giddens's theory of structuration and Bourdieu's notion of habitus in order to understand not only patterns of media consumption in prisons, but also to gain insight into the relationship between media, identity and power. Structuration theory is viewed as an important counter to the prison deprivation literature, the central tenet of which is that imprisonment is an inherently painful and dehumanizing experience during which the prisoner suffers a series of deprivations that fundamentally weaken his or her sense of identity. While this study supports the view that prisons are essentially mortifying environments, it nevertheless endorses Giddens's belief that subordinates are never entirely powerless even in the most bounded of locales. Indeed, this article presents evidence to show that the mass media provide a key source of empowerment for the confined, offering a range of material from which they can create new identities or maintain pre-existing identities, explore their inner selves, form subgroups based on collective fanship, and find autonomy and self-respect in otherwise humiliating and disidentifying circumstances.
Uncanny valley revisited

The 'uncanny valley"'was conceived in 1970 by Prof Masahiro Mori and details a possible relationship between an object's appearance or motion and how people perceive the object. Initially this research was used without validation. Modern technology has enabled initial investigations, summarised here, that conclude further work is required. A good design guideline for humanoid robots is desired if humanoid robots are to assist with an increasingly elderly population, but not yet possible due to technological constraints. Prosthetics is considered a good resource as the user interaction is comparable to the anticipated level of human-robot interaction and there is a wide range of existing devices.
Science Rather Than Advocacy When Reporting IQ Scores

The existence of shifts in mean IQ scores over time is well established. However, on a case-by-case basis, such shifts vary unreliably, rendering specific adjustments to a given individual’s IQ score incalculable. Based upon data presented previously (Hagan, Drogin, & Guilmette, 2008) as well as a review of more recent studies that have further detailed the wide variability of mean score shifts, any proposal to “correct” IQ scores in forensic evaluations due to the “Flynn effect” (FE) is unjustifiable. To offer the court an unreliable new IQ score in place of an allegedly unreliable old one—and to do so specifically in capital murder cases as opposed to any other context—appears far more reflective of result-focused advocacy than objective scientific practice. Forensic psychologists are explicitly encouraged to address likely ranges of IQ score variability and to discuss in relevant detail the strengths and weaknesses of the specific studies—however much at odds these may be—that attempt to define and quantify mean score shifts.
Beyond "The Original Affluent Society": A Culturalist Reformulation [and Comments and Reply]

This paper examines Marshall Sahlins's "Original Affluent Society" in relation to recent developments in modem huntergatherer studies and reveals a theoretical confusion of ecological and cultural perspectives within it which has hitherto been overlooked. Drawing comparatively on three case studies-the Nayaka of South India, the Batek of Malaysia, and the Mbuti of Zaire-it then reformulates Sahlins's argument using the culturalist method of economic analysis. At the same time it demonstrates the explanatory and analytical dimensions of this new method.
A Systematic and Comparative Study of Binary Metal Catalysts for Carbon Nanotube Fabrication Using CVD and Laser Evaporation

Systematic studies to investigate binary catalysts combining the well-established standard transition metals Fe, Co and Ni with less used metals such as Al, Pb, Dy, Gd, Ga and Zn were explored in supported catalyst chemical vapor deposition. The findings show different carbon nanostructures can be obtained depending on the choice of catalyst mix. Comparative studies with Al as a co-catalyst with Fe or Co or Ni were explored in a laser evaporation reactor in both a pure nitrogen environment and a nitrogen environment with additional hydrogen present. The addition of hydrogen etches amorphous carbon leading to cleaner samples. In terms of the obtained carbon nanostructures, the variations among the different binary catalysts were the same for both synthesis routes investigated.
Violence in the night-time economy : key findings from the research

Violent behaviour in and around pubs and clubs on weekend nights presents a significant public health, criminal justice and urban management problem. Many people are injured in such violence, a significant minority of whom are permanently disfigured. In many of these incidents, alcohol has been consumed. The key findings from published UK and international research on violence in the night-time economy and its relation to alcohol use are presented here.
A Decade of Research in Foreign Language Teacher Education

all authored position papers calling for a renewed interest in and a revitalized perspective on foreign language learning in the United States. Yet these agencies have not addressed, in any depth, issues concerning the teaching of foreign language as they relate to teachers of foreign languages. Granted, many of these commissions have recommended that foreign language teachers be given opportunities for professional development through overseas experiences or through additional courses. The commissions have not, however, addressed the preprofessional development of these teachers. Specifically, they have failed to address the types of educational experience both in terms of language and pedagogical content--these individuals receive as part of their teacher education programs. THE PROBLEM
Co‐administration of citalopram and clozapine: effect on plasma clozapine levels

Antidepressants are frequently used in the treatment of depressive symptoms associated with schizophrenia. In patients faking clozapine, choice of antidepressant is complicated by additive pharmacodynamic effects and by pharmacokinetic interactions. We predicted that citalopram would not elevate plasma clozapine levels when the two drugs were co-administered because it does not inhibit the relevant enzyme systems. In this preliminary study of five patients given citalopram and clozapine there was no overall change in mean clozapine levels. Based on this limited evidence, citalopram might be the antidepressant of choice in patients taking clozapine.
Tolerance of Rape: A Sexist or Antisocial Attitude?

A prison sample and a community control group were used to develop a scale of Rape Attitudes (tolerance of rape) and to validate a modified version of the Gough Socialization Scale. A university student sample and an adolescent sample completed the Rape Attitudes scale and a scale of attitudes toward heterosexual relationships. Males in the adolescent sample also completed the modified Cough Socialization Scale. For both university students and adolescents, and for both males and females, tolerance of rape was associated with sexist attitudes toward heterosexual relationships. For the male adolescents, tolerance of rape and sexist attitudes were associated with antisocial, delinquent personality tendencies. The relationship between tolerance of rape and sexist attitudes was stronger than the relationship between tolerance of rape and an antisocial personality.
Study on the User Adoption of a Convergent Evolved Technology, Mobile IPTV

Convergence has recently become a key word in all industries including telecommunications. The most noted case is the media and IT convergence in Korea. The reason for this is that broadcasting is under the influence of IT technology development, such as broadband, digitalized, and interactive trajectories. Mobile Internet Protocol Television (IPTV) is one of the converging technologies, which also includes mobile handsets and IPTV. Mobile IPTV will offer TV content via a mobile IP network such as WiMax or 4G all-IP[1]. It is important to forecast and understand new technology developments, because precise forecasting ensures the successful market entrance of new technologies. In the case of Mobile IPTV, a market study is more important because technology development to realize service will be completed in a few years.In this paper, we study mobile IPTV adoption using the suggested model, namely CE-TAM that evaluates convergent technology. We expect to get some implications; new adoption model for convergent evolved technology will be verified and managerial strategies of mobile IPTV will be set up
Investigating Musical Performance Anxiety among Music College Singing Students: A quantitative analysis

Due to the common and undesirable effects of 'stage fright' among perform ing musicians, the current study has been undertaken to re-examine the issue of performance anxiety among second- and third-year vocal studies students taking their mid-year examinations at the Guildhall School of Music in London. The results reveal females to be more anxious compared to the norms regarding anxiety both as a personality trait and as a state condition during the anticipation of a jury situation. In addition, the study confirms the suggestion in the literature that a proportional relationship exists between the trait and state aspects of anxiety, where state anxiety levels get higher as trait anxiety increases and vice versa. Regarding the students' achievement as indicated in their final marks, it has been shown that not only will the more advanced musicians, in terms of training and experience, perform better under anxious conditions but they also benefit from their higher levels of pre-performance anxiety.
Measurement error in research on human resources and firm performance: How much error is there and how does it influence effect size estimates?

Studies of the relationship between human resource (HR) practices and firm performance typically use a single respondent to assess firm level HR practices or HR effectiveness. However, previous research in other substantive areas suggests that rater differences are a potentially important source of measurement error. We demonstrate analytically the potential consequences of both random and systematic measurement error in research on HR and firm performance. However, our main focus is on random error and we show how generalizability theory can be applied to obtain better estimates of reliability by simultaneously recognizing multiple sources (e.g., items, raters) of random measurement error. These more inclusive reliability estimates, in turn, offer the possibility of more precisely quantifying substantive relationships in the HR and firm performance literature. In our sample, reliabilities (as estimated by generalizability coefficients) for single-rater assessments of HR variables were generally below . 50. This degree of measurement error, if present in substantive studies on HR and firm performance, could lead to considerable bias, given that an unstandardized regression coefficient is corrected for measurement error in the independent variable by dividing by its reliability coefficient (not its square root). We also found only limited convergent validity between HR and line managers ratings of a second type of HR measure, HR effectiveness. In general, our findings suggest that future researchers need to devote greater attention to measurement error and construct validity issues. Our study provides an example of how generalizability theory can be useful in this pursuit.
Changes in children's nature-based experiences near home: from spontaneous play to adult-controlled, planned and organised activities

A qualitative case study from Brumunddalen, Norway, indicates that children's use of nature areas near their homes have changed substantially from being spontaneous and self-initiated to being part of planned, organised and adult-controlled activities. This study explores the association between changes in outdoor play and wider patterns of change in childhood today, as increasing amounts of play time is spent in institutions and organised activities, or occupied by computer and internet usage. The paper discusses these effects in terms of social relations as well as children's identity formation. The subject was investigated through adults' memories of their own childhood and their observations of children's practices.
An authentication scheme for fast handover between WiFi access points

In this paper, we propose an authentication scheme that is designed to reduce the authentication delay during a WiFi handover process. We observe that the largest part of the delay is due to the remote communications between the access point and the AAA server that authorizes the access to the network. In order to eliminate remote communications, our scheme uses pre-authorization, and it pre-distributes authentication information to the access points that are the potential targets of a future handover. This ensures that only local communications (between the mobile station and the access point) take place during the handover itself. We describe the design of our scheme, as well as report on a proofof-concept implementation. Our validation results show that our scheme breaks the dependency of the authentication delay on the round-trip time between the access point and the AAA server. This makes our scheme applicable in real time applications such as telephony and video streaming for WiFi users.
Society's Choices — Social and Ethical Decision Making in Biomedicine

Breakthroughs in biomedicine often lead to new life-giving treatments but may also raise troubling, even life-and-death, quandaries. Society's Choices discusses ways for people to handle today's bioethics issues in the context of America's unique history and culture--and from the perspectives of various interest groups. The book explores how Americans have grappled with specific aspects of bioethics through commission deliberations, programs by organizations, and other mechanisms and identifies criteria for evaluating the outcomes of these efforts. The committee offers recommendations on the role of government and professional societies, the function of commissions and institutional review boards, and bioethics in health professional education and research. The volume includes a series of 12 superb background papers on public moral discourse, mechanisms for handling social and ethical dilemmas, and other specific areas of controversy by well-known experts Ronald Bayer, Martin Benjamin, Dan W. Brock, Baruch A. Brody, H. Alta Charo, Lawrence Gostin, Bradford H. Gray, Kathi E. Hanna, Elizabeth Heitman, Thomas Nagel, Steven Shapin, and Charles M. Swezey.
The Ideal Candidate

The view of image as a transaction between what a candidate does and the evaluative response that voters have to it creates at least three critical questions as yet unanswered in the literature of political communication. First, although the power of the media to affect the success or failure of political campaigns and candidates has been demonstrated by researchers and is popularly believed, do the views of individual media members regarding the qualities necessary for presidential candidates differ significantly from those of the electorate? Second, although voters share many beliefs about the personal qualities that presidential candidates ought to possess, do these attributes vary from presidential election to election? Finally, although voter assessment of a candidate's image is a major determinant of voter behavior and voters have a mental picture of an ideal candidate that they use to evaluate actual candidates, do the evaluative dimensions differ by party affiliation? The answers to these questions were determined from the results of a survey of 236 professional journalists covering and 444 voting citizens attending presidential rallies in New Hampshire in 1988 and 1992.
β1-Integrin Signaling Mediates Premyelinating Oligodendrocyte Survival But Is Not Required for CNS Myelination and Remyelination

Previous reports, including transplantation experiments using dominant-negative inhibition of β1-integrin signaling in oligodendrocyte progenitor cells, suggested that β1-integrin signaling is required for myelination. Here, we test this hypothesis using conditional ablation of the β1-integrin gene in oligodendroglial cells during the development of the CNS. This approach allowed us to study oligodendroglial β1-integrin signaling in the physiological environment of the CNS, circumventing the potential drawbacks of a dominant-negative approach. We found that β1-integrin signaling has a much more limited role than previously expected. Although it was involved in stage-specific oligodendrocyte cell survival, β1-integrin signaling was not required for axon ensheathment and myelination per se. We also found that, in the spinal cord, remyelination occurred normally in the absence of β1-integrin. We conclude that, although β1-integrin may still contribute to other aspects of oligodendrocyte biology, it is not essential for myelination and remyelination in the CNS.
Fixed Point Polynomials of Permutation Groups

In this paper we study, given a group $G$ of permutations of a finite set, the so-called fixed point polynomial $\sum_{i=0}^{n}f_{i}x^{i}$, where $f_{i}$ is the number of permutations in $G$ which have exactly $i$ fixed points. In particular, we investigate how root location relates to properties of the permutation group. We show that for a large family of such groups most roots are close to the unit circle and roughly uniformly distributed round it. We prove that many families of such polynomials have few real roots. We show that many of these polynomials are irreducible when the group acts transitively. We close by indicating some future directions of this research. A corrigendum was appended to this paper on 10th October 2014.
