Oh, What a Tangled World Wide Web We Weave: An Analysis of Washington\u27s Computer Spyware Act in a National Context

Spyware affects businesses as well as individuals. Spyware can expose a company\u27s confidential information, slow down computers and networks, and destroy data. Employees lose efficiency while waiting for IT staff to fix the various problems caused by spyware, which increases costs. Accordingly, spyware is not just a minor annoyance suffered by individual Internet users; rather, it harms American businesses and the economy as well

Dynamical pattern formation during growth of a dual-species Bose-Einstein condensate

We simulate the growth of a dual species Bose-Einstein condensate using a Gross-Pitaevskii equation with an additional gain term giving rise to the growth. Such growth occurs during simultaneous evaporative cooling of a mixture of two gases. The ground state of a dual condensate is normally either a miscible mixture, or an immiscible phase with two spatially separated components. In a cigar trap the ground state typically consists of one component in the center, and the other component flanking it. Our simulations show that when the condensates are formed in a cigar trap and the mixture is phase separated, then the final state upon the end of the growth is generally far from the true ground state of the system. Instead it consists of multiple, interleaved bubbles of the two species. Such a pattern was observed recently in an experiment by Wieman's group at JILA, and our simulations are in good qualitative agreement with the experiment. We explain the pattern formation as due to the onset of modulation instability during growth, and study the dependence of the final state pattern on various parameters of the system

A Five-Step Process for Interactive Parent–Adolescent Communication About HIV Prevention: Advice From Parents Living with HIV/AIDS

The authors investigated how parents living with HIV/AIDS communicate about HIV prevention with their 10- to 18-year-old children. Semistructured interviews with 76 mothers and fathers were analyzed for (a) their experiences discussing HIV prevention with adolescents and (b) advice for other parents about how to best broach HIV-related topics. Interactive conversations were regarded as particularly effective. A five-step process for interactive communication emerged as a result of these discussions. Parents emphasized that adolescents should have a “voice” and a “choice” in HIV-related talks. Health care professionals can facilitate adolescent sexual health by encouraging parents to actively involve their children in discussions about HIV prevention. Future HIV prevention programs could benefit by providing parents with appropriate tools to foster interactive discussions about sexual health with adolescents

Communicating in Complex Situations: A Normative Approach to HIV-Related Talk Among Parents Who Are HIV+

Parents with HIV/AIDS are confronted with unique challenges when discussing HIV-related information with their children. Strategies for navigating these challenges effectively have not been systematically examined. In this study, we conducted in-depth interviews with 76 parents with HIV/AIDS who had children ages 10–18 years. Guided by O\u27Keefe and Delia\u27s definition of a complex communication situation and Goldsmith\u27s normative approach to interpersonal communication, we examined parents’ goals for discussing HIV-related information, factors that made conversations challenging, and instances where these conversational purposes conflicted with one another. Our data reveal the following parent–adolescent communication predicaments: relaying safety information about HIV while minimizing child anxiety, modeling open family communication without damaging one\u27s parental identity, and balancing parent–child relational needs amid living with an unpredictable health condition. Parents also described a variety of strategies for mitigating challenges when discussing HIV-related topics. Strategies parents perceived as effective included reframing HIV as a chronic, manageable illness; keeping talk educational; and embedding HIV-related topics within more general conversations. The theoretical and practical applications of these findings are discussed with regard to their relevance to health communication scholars and HIV care professionals

Evaluation of Asperger Syndrome in Youth Presenting to a Gender Dysphoria Clinic

Purpose: There is evolving evidence that children and adolescents with gender dysphoria have higher-than-expected rates of autism spectrum disorder (ASD), yet clinical data on ASD among youth with gender dysphoria remain limited, particularly in North America. This report aims to fill this gap. Methods: We conducted a retrospective review of patient chart data from 39 consecutive youth ages 8 to 20 years (mean age 15.8 years, natal male: n?=?22, natal female: n?=?17) presenting for evaluation at a multidisciplinary gender clinic in a large U.S. pediatric hospital from 2007 to 2011 to evaluate the prevalence of ASD in this patient population. Results: Overall, 23.1% of patients (9/39) presenting with gender dysphoria had possible, likely, or very likely Asperger syndrome as measured by the Asperger Syndrome Diagnostic Scale (ASDS). Conclusion: These findings are consistent with growing evidence supporting increased prevalence of ASD in gender dysphoric children. To guide provision of optimal clinical care and therapeutic intervention, routine assessment of ASD is recommended in youth presenting for gender dysphoria.Peer Reviewedhttps://deepblue.lib.umich.edu/bitstream/2027.42/140161/1/lgbt.2015.0070.pd

Parent-Child Sexual Communication Among Middle School Youth

Middle school youth (N=1472) in Central Indiana completed a survey about parent-adolescent sexual communi-cation. Being older, female, mixed race, ever had sex, ever arrested, and higher HIV knowledge were associatedwith more frequent sexual communication

The utility of MAS5 expression summary and detection call algorithms

<p>Abstract</p> <p>Background</p> <p>Used alone, the MAS5.0 algorithm for generating expression summaries has been criticized for high False Positive rates resulting from exaggerated variance at low intensities.</p> <p>Results</p> <p>Here we show, with replicated cell line data, that, when used alongside detection calls, MAS5 can be both selective and sensitive. A set of differentially expressed transcripts were identified that were found to be changing by MAS5, but unchanging by RMA and GCRMA. Subsequent analysis by real time PCR confirmed these changes. In addition, with the Latin square datasets often used to assess expression summary algorithms, filtered MAS5.0 was found to have performance approaching that of its peers.</p> <p>Conclusion</p> <p>When used alongside detection calls, MAS5 is a sensitive and selective algorithm for identifying differentially expressed genes.</p

Multiple genome-wide analyses of smoking behavior in the Framingham Heart Study

BACKGROUND: Cigarette smoking behavior may have a genetic basis. We assessed evidence for quantitative trait loci (QTLs) affecting the maximum number of cigarettes smoked per day, a trait meant to quantify this behavior, using data collected over 40 years as part of the Framingham Heart Study's original and offspring cohorts. RESULTS: Heritability was estimated to be approximately 21% using variance components (VC) methods (SOLAR), while oligogenic linkage and segregation analysis based on Bayesian Markov chain Monte Carlo (MCMC) methods (LOKI) estimated a mean of two large QTLs contributing approximately 28% and 20%, respectively, to the trait's variance. Genome-wide parametric (FASTLINK) and VC linkage analyses (SOLAR) revealed several LOD scores greater than 1.0, with peak LOD scores using both methods on chromosomes 2, 17, and 20; multi-point MCMC methods followed up on these chromosomes. The most robust linkage results were for a QTL between 65 and 84 cM on chromosome 20 with signals from multiple sex- and age-adjusted analyses including two-point LOD scores of 1.30 (parametric) and 1.07 (heritability = 0.17, VC) at 70.51 cM, a multi-point LOD score of 1.50 (heritability = 0.20, VC) at 84 cM, and an intensity ratio of 12.0 (MCMC) at 65 cM. CONCLUSION: Familial aggregation of the maximum number of cigarettes smoked per day was consistent with a genetic component to this behavior, and oligogenic segregation analyses using MCMC suggested two important QTLs. Linkage signals on chromosome 20 between 65 and 84 cM were seen using multiple analytical methods. No linkage result, however, met genome-wide statistical significance criteria, and the true relationship between these regions and smoking behavior remains unclear
