Outsourcing of IT functions has become a widespread corporate practice, which has naturally led to concerns among IT works about how this affects their jobs. The issue is complex, and many companies are bringing their IT functions back inhouse. In light of this complexity, what skills do IT workers need to be com-petitive? We address this question first by reviewing the literature and then by examining two corporate case studies that have dealt with outsourcing issues. Based on this view of outsourcing, we discuss the skills that can provide a com-petitive advantage in the current environment.  相似文献

This study investigated child welfare practitioners’ ratings of the severity of parental discipline practices. Ratings varied by the type of act, age of the child, and by chronicity. Exploratory investigation into changes across time found that current practitioners (N = 27) rated several practices (e.g. spanking and shaking) as more severe than did professionals (N = 24) sampled in 1977. Results underscore the complexity of defining child maltreatment and offer implications for practitioners, applied researchers, and child welfare policy makers.The authors Stephen D.

Elimination of a nuisance variable is often non‐trivial and may involve the evaluation of an intractable integral. One approach to evaluate these integrals is to use the Laplace approximation. This paper concentrates on a new approximation, called the partial Laplace approximation, that is useful when the integrand can be partitioned into two multiplicative disjoint functions. The technique is applied to the linear mixed model and shows that the approximate likelihood obtained can be partitioned to provide a conditional likelihood for the location parameters and a marginal likelihood for the scale parameters equivalent to restricted maximum likelihood (REML). Similarly, the partial Laplace approximation is applied to the t‐distribution to obtain an approximate REML for the scale parameter. A simulation study reveals that, in comparison to maximum likelihood, the scale parameter estimates of the t‐distribution obtained from the approximate REML show reduced bias.  相似文献

This study examined whether the prevalence of self-reportedhealth risk behaviors among high school students varied by surveysetting (school versus home) and mode of administration (paperand pencil versus computer). Students in grades 9 and 11 wereassigned randomly to one of four conditions—school paper-and-pencilinstrument (PAPI), school computer-assisted self-interview (CASI),home PAPI, and home CASI. During the spring of 2004, 4,506 studentscompleted identically worded questionnaires based on the YouthRisk Behavior Survey questionnaire. Logistic regression analysescontrolling for sex, grade, and race/ethnicity revealed thatsetting was associated significantly with the reporting of 30of the 55 risk behaviors examined, and mode was associated significantlywith the reporting of 7 of the 55 behaviors. For all behaviorswith a significant setting main effect, the odds of reportingthe behavior were greater among students who completed questionnairesat school than among students who completed questionnaires athome. For all behaviors with a significant mode main effect,PAPI mode students had lower odds of reporting the behaviorthan CASI mode students. Because social measurement researchassumes that higher prevalence estimates are more valid thanlower estimates, methodological factors shown to increase estimates,such as setting and mode, should be considered when planningsurveys.  相似文献

A team building activity, the image exchange, was helpful to interdisciplinary teams in clarifying perceptions and opinions of participants about the roles of each discipline (child welfare, domestic violence, mental health, and substance abuse workers) at a five-day interdisciplinary training workshop. Discussion of team members’ perceptions and views provided opportunities to develop insights about misperceptions. Training in team development and role clarification provided a foundation for the development of effective interdisciplinary collaboration, which may improve interdisciplinary practice.Dr. Packard is an Associate Professor and Dr. Jones is a Professor in the School of Social Work at SDSU.

The success of the Global Polio Eradication Initiative promises to bring large benefits, including sustained improvements in quality of life (i.e., cases of paralytic disease and deaths avoided) and costs saved from cessation of vaccination. Obtaining and maintaining these benefits requires that policymakers manage the transition from the current massive use of oral poliovirus vaccine (OPV) to a world without OPV and free of the risks of potential future reintroductions of live polioviruses. This article describes the analytical journey that began in 2001 with a retrospective case study on polio risk management and led to development of dynamic integrated risk, economic, and decision analysis tools to inform global policies for managing the risks of polio. This analytical journey has provided several key insights and lessons learned that will be useful to future analysts involved in similar complex decision-making processes.  相似文献

Staphylococcus aureus is a gram-positive, enterotoxin-producing coccus. It is a hardy organism and known to survive over a wide range of water activities, pH values, and temperatures. The objective of this study was to model the survival or gradual inactivation of S. aureus ATCC 13565 in intermediate moisture foods (IMFs). Various initial concentrations (approximately 10(1), 10(2), 10(3), and 10(4) CFU/g) were used to inoculate three different IMFs (beefsteak, bread, and chicken pockets). Viable counts were determined up to 60 days using tryptic soy agar. Inoculum size did not influence the survival or gradual inactivation of S. aureus in these foods. The rate of change (increase or decrease) in log CFU/day was calculated for every consecutive pair of data points and by linear regression for each inactivation curve. Both consecutive pair and linear regression rates of change were fit to logistic distributions (with parameters alpha and beta) for each food. Based on the distribution parameters, survival or gradual inactivation of S. aureus was predicted by computer simulation. The simulations indicated an overall decline in S. aureus population over time, although a small fraction of samples in the consecutive pair simulation showed a slight population increase even after 60 days, consistent with the observed data. Simulation results were compared to predictions from other computer models. The models of Stewart et al., were fail-safe, predicting the possibility of significant growth only after > 3,000 days. The USDA pathogen modeling program predictions were found to be fail-dangerous, predicting declines at least four times faster than observed.  相似文献

This paper explores current trends in religious practice, observance and belief in Ulster Protestantism for elements of continuity and change. Using historical and survey data it is clear that there are strong elements of both. However, Protestant religiosity is not changing to the point that it constitutes secularisation, as sociologists of religion understand it. Nor are new trends in religiosity weakening ethno‐national identities in Northern Ireland. This is because political identities are socially reproduced in ways that are independent of their religious roots and are thus unaffected by patterns of religiosity. Likely changes in Protestant religiosity in the future therefore offer no immediate panacea for altering the dynamics of Northern Irish politics.  相似文献

Drawing on interviews with more than 80 scientists on two university campuses, we create a typology that offers insights into how transformations in the nature and locus of life science innovation influence academic careers and work practices. Our analyses suggest that a strong outcome of increased academic concern with research commercialization is the appearance of new fault lines among faculty, between faculty and students, and even between scientists' interests and those of their institutions. We argue that life science commercialization is driven by a mix of new funding opportunities, changing institutional mandates for universities, and novel research technologies that bring basic research and product development into much closer contact. The rise of patenting and commercially motivated technology transfer on U.S. campuses is altering faculty work practices and relationships, while transforming the criteria by which success is determined and rewards are allocated. Through close analysis of interviews with four researchers who typify a range of academic responses to commercialism, we demonstrate emerging patterns of conflict and agreement in faculty responses to commercial opportunities in the life sciences.  相似文献
