Selected AbstractsVisualizing feature evolution of large-scale software based on problem and modification report dataJOURNAL OF SOFTWARE MAINTENANCE AND EVOLUTION: RESEARCH AND PRACTICE, Issue 6 2004Michael Fischer Abstract Gaining higher-level evolutionary information about large software systems is a key challenge in dealing with increasing complexity and architectural deterioration. Modification reports and problem reports (PRs) taken from systems such as the concurrent versions system (CVS) and Bugzilla contain an overwhelming amount of information about the reasons and effects of particular changes. Such reports can be analyzed to provide a clearer picture about the problems concerning a particular feature or a set of features. Hidden dependencies of structurally unrelated but over time logically coupled files exhibit a good potential to illustrate feature evolution and possible architectural deterioration. In this paper, we describe the visualization of feature evolution by taking advantage of this logical coupling introduced by changes required to fix a reported problem. We compute the proximity of PRs by applying a standard technique called multidimensional scaling (MDS). The visualization of these data enables us to depict feature evolution by projecting PR dependence onto (a) feature-connected files and (b) the project directory structure of the software system. These two different views show how PRs, features and the directory tree structure relate. As a result, our approach uncovers hidden dependencies between features and presents them in an easy-to-assess visual form. A visualization of interwoven features can indicate locations of design erosion in the architectural evolution of a software system. As a case study, we used Mozilla and its CVS and Bugzilla data to show the applicability and effectiveness of our approach. Copyright © 2004 John Wiley & Sons, Ltd. [source] A dose,response perspective on college drinking and related problemsADDICTION, Issue 2 2010Paul J. Gruenewald ABSTRACT Aims In order to examine the degree to which heavy drinking contributes to risks for problems among college drinkers this paper develops and tests a dose,response model of alcohol use that relates frequencies of drinking specific quantities of alcohol to the incidence of drinking problems. Methods A mathematical model was developed that enabled estimation of dose,response relationships between drinking quantities and drinking problems using self-report data from 8698 college drinkers across 14 campuses in California, USA. The model assumes that drinking risks are a direct monotone function of the amount consumed per day and additive across drinking days. Drinking problems accumulate across drinking occasions and are the basis for cumulative reports of drinking problems reported by college drinkers. Results Statistical analyses using the model showed that drinking problems were related to every drinking level, but increased fivefold at three drinks and more gradually thereafter. Problems were associated most strongly with occasions on which three drinks were consumed, and more than half of all reported problems were related to occasions on which four or fewer drinks were consumed. There were some important differences in dose,responsiveness between men and women and between different groups of ,light', ,moderate' and ,heavier' drinkers. Conclusion Many problems among college students are associated with drinking relatively small amounts of alcohol (two to four drinks). Programs to reduce college drinking problems should emphasize risks associated with low drinking levels. [source] The oral health of street-recruited injecting drug users: prevalence and correlates of problemsADDICTION, Issue 11 2008Anne-Marie Laslett ABSTRACT Aims To examine the effects of a series of injecting drug users' (IDU) characteristics and drug use behaviours upon the self-reported oral health of a sample of IDU. Design Cross-sectional survey. Setting Melbourne, Australia. Participants A total of 285 IDU recruited through needle and syringe programmes, snowballing and outreach across six sites. Measurements Structured survey that collected information on current drug use patterns, self-reported blood-borne virus status and general health factors, including open-ended questions on past-year dental health problems. Findings Sixty-eight per cent of the sample reported dental problems that were commonly severe and caused dental pain. Despite these reported problems, almost half the sample had not visited the dentist in the 12 months prior to the survey. Participants who were older, and reported homelessness, not eating every day and more common injection of amphetamines rather than heroin in the previous month, were more likely to report having a past-year dental problem. Conclusions Dental problems in IDUs are common but few receive treatment. Further, those using amphetamines, with poor housing, hygiene and poor nutrition, are most at risk. Programmes designed to improve the oral health of IDU need to be developed and implemented in a manner amenable to the varying social circumstances of this marginalized group in the community. [source] What is worse for your sex life: Starving, being depressed, or a new baby?INTERNATIONAL JOURNAL OF EATING DISORDERS, Issue 7 2007Dip Clin Psych, Frances A. Carter PhD Abstract Objective: To compare the current sexual functioning of women in an intimate relationship with anorexia nervosa, with major depression, and in the postpartum period. Method: Complete data were available for 76 women who reported being in an intimate relationship (anorexia = 10; depression = 24; postpartum = 42). Sexual functioning was assessed using the Social Adjustment Scale (Weissman and Bothwell, Arch Gen Psychiatry, 33, 1111,1115, 1976). Results: Significant differences were found among groups for the frequency of sex (p =.03) and problems with sex (p < .001), but not for enjoyment of sex (p = .55). In the previous 2 weeks, women with anorexia nervosa or major depression were more likely to have had sex than postpartum women, but were also more likely to have had sexual problems than postpartum women. Most women with anorexia nervosa, women with major depression, and postpartum women reported enjoying sex. Conclusion: Women with anorexia nervosa and women with major depression who are in an intimate relationship report a similar profile of current sexual functioning that is different from postpartum women both in the frequency of sexual encounters and in reported problems with sex. © 2007 by Wiley Periodicals, Inc.

[source] Service delivery in older patients with bipolar disorder: a review and development of a medical care modelBIPOLAR DISORDERS, Issue 6 2008Amy M Kilbourne Objectives:, Medical comorbidities, especially cardiovascular disease (CVD), occur disproportionately in older patients with bipolar disorder. We describe the development, implementation, and feasibility/tolerability results of a manual-based medical care model (BCM) designed to improve medical outcomes in older patients with bipolar disorder. Methods:, The BCM consisted of (i) self-management sessions focused on bipolar disorder symptom control, healthy habits, and provider engagement, (ii) telephone care management to coordinate care and reinforce self-management goals, and (iii) guideline dissemination focused on medical issues in bipolar disorder. Older patients with bipolar disorder and a CVD-related risk factor (n = 58) were consented, enrolled, and randomized to receive BCM or usual care. Results:, Baseline assessment (mean age = 55, 9% female, 9% African American) revealed a vulnerable population: 21% were substance users, 31% relied on public transportation, and 22% reported problems accessing medical care. Evaluation of BCM feasibility revealed high overall patient satisfaction with the intervention, high fidelity (e.g., majority of self-management sessions and follow-up contacts completed), and good tolerability (dropout rate <5%). Use of telephone contacts may have mitigated barriers to medical care (e.g., transportation). Conclusions:, The BCM is a feasible model for older, medically ill patients with bipolar disorder, and could be an alternative to more costly treatment models that involve co-location and/or additional hiring of medical providers in mental health clinics. Future research directions pertinent to the development of the BCM and other medical care models for older patients with bipolar disorder include assessment of their long-term effects on physical health and their cost-effectiveness across different treatment settings. [source] Impact of faecal incontinence severity on health domainsCOLORECTAL DISEASE, Issue 3 2005M. Deutekom Abstract Objective Faecal incontinence is a problem that can have a major impact on the quality of life of those affected. Our aim was to relate the severity of faecal incontinence to the impact on several general health domains. Methods Patients from a prospective diagnostic cohort study, performed in 16 medical centres in the Netherlands, were invited to the study. The severity of incontinence was determined with the Vaizey score, which ranges from 0 (continent) to 24 (totally incontinent). Based on their Vaizey score, patients were assigned to one of five severity categories. All patients completed the EuroQol-5D instrument, which evaluates the existence of problems on five health domains: mobility, self-care, usual activities, pain/discomfort and anxiety/depression. Results Data from 259 consecutive patients (25 male) could be analysed. Their mean age was 59 years (SD ± 12). The mean duration of faecal incontinence was 8.1 years (SD ± 8). The proportion of patients reporting problems rose significantly with increasing severity of faecal incontinence in the domains of usual activities (ranging from 36% in the least severe group to 71% in the most severe group (P < 0.001)), pain/discomfort (ranging from 35% to 60%; P = 0.025), and anxiety/depression (ranging from 23% to 49%; P = 0.037). No significant trends could be observed in the domains of mobility and self-care. Conclusion There exists a significant relation between severity of incontinence and frequency of reported problems in the domains of usual activities, pain/discomfort and anxiety/depression.
