Hello, my name is ____, and I'm an alcoholic: A study of organizational identification and commitment to Alcoholics Anonymous

This study's purpose was to investigate the communicative processes involved in organizational identification and commitment in a nonwork setting. It considers how organizational identification, organizational commitment, and social identity processes inform how individuals attach to Alcoholics Anonymous and how this attachment relates to their achievement of sobriety, using qualitative methodology. Five findings emerged. First was strong evidence of messages encouraging identification consistent with traditional perspectives on identification in workplace organizations. Second, personal identity change is necessary to the process of attaining sobriety, and social identification processes at work were associated with drinking problems. Third, messages facilitated individual behavioral change by accepting human limitation. Fourth, participants connected values espoused by the organization with a change in decision premises--changed personal decision-making and life choices--as a result of working the 12 steps. Fifth, participants reported organizational identification and commitment behaviors only after they had attained sobriety by working the 12 Steps

Responsible Integration of Behavioral Science in Computer Science Research and Development

Cross disciplinary research is essential for technological innovation. For decades, computer science (Comp Sci) has leveraged behavior science (Behav Sci) research to create innovative products and improve end user experience. Despite the natural challenges that come with cross disciplinary work, there are no published manuscripts outlining how to responsibly integrate Behav Sci into Comp Sci research and development. This publication fills this critical gap by discussing important differences between Behav Sci and Comp Sci, particularly with regard to how each field fits under the umbrella of science and how each field conceptualizes data. We then discuss the consequences of misusing Behav Sci and provide examples of technology efforts that drew inappropriate or unethical conclusions about their behavioral data. We discuss in detail common errors to avoid at each stage of the research process, which we condensed into a useful checklist to use as a tool for teams integrating Behav Sci in their work. Finally, we include examples of good applications of Behav Sci into Comp Sci research, the design of which can inform and strengthen digital government, e-commerce, defense, and many other areas of information technology

Comparison of IMU Measurements of Curling Stone Dynamics with a Numerical Model

Abstract Despite almost a century of research, the question of what causes a curling stone to curl (move perpendicular to its initial direction of motion) has no complete answer. Many hypotheses have been formulated, but none has been able to account quantitatively for the full magnitude of the observed curl. The objective of this research was to equip a curling stone with an inertial measurement unit (IMU) and measure its motion, in order to verify a previously published, numerical model of curling stone dynamics. Low cost, small size, accuracy, ease of programming and operation, wireless data communication, and a data-sampling rate near 1 kHz, were selection criteria and constraints for the instrument package. We used the MicroStrain 3DM-GX4-25 system. This is a MEMS-based IMU with a tri-axial gyroscope and a tri-axial linear accelerometer. It was mounted and interfaced with a Bluetooth transmitter, on a curling stone handle. The data were streamed to a host laptop and displayed graphically in real time. Post-processing of the data included filtering and time-integration in order to obtain linear and angular velocities, and displacements. We have compared our experimental results with trajectory data calculated using a previously published numerical model, based on a thermodynamic approach to ice friction. While the observed longitudinal and angular motions are captured reasonably well by the model (errors of about 5% or less), no curl is predicted by the model

Contrasting Epidemic Histories Reveal Pathogen-Mediated Balancing Selection on Class II MHC Diversity in a Wild Songbird

The extent to which pathogens maintain the extraordinary polymorphism at vertebrate Major Histocompatibility Complex (MHC) genes via balancing selection has intrigued evolutionary biologists for over half a century, but direct tests remain challenging. Here we examine whether a well-characterized epidemic of Mycoplasmal conjunctivitis resulted in balancing selection on class II MHC in a wild songbird host, the house finch (Carpodacus mexicanus). First, we confirmed the potential for pathogen-mediated balancing selection by experimentally demonstrating that house finches with intermediate to high multi-locus MHC diversity are more resistant to challenge with Mycoplasma gallisepticum. Second, we documented sequence and diversity-based signatures of pathogen-mediated balancing selection at class II MHC in exposed host populations that were absent in unexposed, control populations across an equivalent time period. Multi-locus MHC diversity significantly increased in exposed host populations following the epidemic despite initial compromised diversity levels from a recent introduction bottleneck in the exposed host range. We did not observe equivalent changes in allelic diversity or heterozygosity across eight neutral microsatellite loci, suggesting that the observations reflect selection rather than neutral demographic processes. Our results indicate that a virulent pathogen can exert sufficient balancing selection on class II MHC to rescue compromised levels of genetic variation for host resistance in a recently bottlenecked population. These results provide evidence for Haldane's long-standing hypothesis that pathogens directly contribute to the maintenance of the tremendous levels of genetic variation detected in natural populations of vertebrates

The COMBREX Project: Design, Methodology, and Initial Results

© 2013 Brian P. et al.Prior to the “genomic era,” when the acquisition of DNA sequence involved significant labor and expense, the sequencing of genes was strongly linked to the experimental characterization of their products. Sequencing at that time directly resulted from the need to understand an experimentally determined phenotype or biochemical activity. Now that DNA sequencing has become orders of magnitude faster and less expensive, focus has shifted to sequencing entire genomes. Since biochemistry and genetics have not, by and large, enjoyed the same improvement of scale, public sequence repositories now predominantly contain putative protein sequences for which there is no direct experimental evidence of function. Computational approaches attempt to leverage evidence associated with the ever-smaller fraction of experimentally analyzed proteins to predict function for these putative proteins. Maximizing our understanding of function over the universe of proteins in toto requires not only robust computational methods of inference but also a judicious allocation of experimental resources, focusing on proteins whose experimental characterization will maximize the number and accuracy of follow-on predictions.COMBREX is funded by a GO grant from the National Institute of General Medical Sciences (NIGMS) (1RC2GM092602-01).Peer Reviewe

Different sexed and gendered bodies demand different ways of thinking about policy and practice

We live in an increasingly multi-sexed and gendered society. Social work professionals often are well informed about cultural sensitivities in relation to race, ethnicity and sexual orientation. But is the same true of concepts of sex and gender diversity and the social sensitivities that are involved here? Do social care professionals have the appropriate policies and skills to manage the needs of differently sexed and gendered people? This paper outlines the social emergence of the transgender community, signalling to social care practitioners that they should review existing practices and policies to ensure they are addressing the needs of this diverse community. Attention is drawn to particular difficulties 'trans' people have experienced when drawn into the social care arena. The paper suggests points of reference for reflexive practice that may support practitioners working with this diverse group of people and those who are interested in emancipatory practice

Bioaccumulation and ecotoxicity of carbon nanotubes

Carbon nanotubes (CNT) have numerous industrial applications and may be released to the environment. In the aquatic environment, pristine or functionalized CNT have different dispersion behavior, potentially leading to different risks of exposure along the water column. Data included in this review indicate that CNT do not cross biological barriers readily. When internalized, only a minimal fraction of CNT translocate into organism body compartments. The reported CNT toxicity depends on exposure conditions, model organism, CNT-type, dispersion state and concentration. In the ecotoxicological tests, the aquatic organisms were generally found to be more sensitive than terrestrial organisms. Invertebrates were more sensitive than vertebrates. Single-walled CNT were found to be more toxic than double-/multi-walled CNT. Generally, the effect concentrations documented in literature were above current modeled average environmental concentrations. Measurement data are needed for estimation of environmental no-effect concentrations. Future studies with benchmark materials are needed to generate comparable results. Studies have to include better characterization of the starting materials, of the dispersions and of the biological fate, to obtain better knowledge of the exposure/effect relationships
