In recent years, there has been a renewed interest in the criminal victimization of elderly persons. Given that homicides of the elderly are thought to occur primarily in the context of robbery/burglary situations, this study seeks to identify situational as well as structural and cultural factors that influence the murder of older persons. In particular, it has been noted that Southern culture promotes a notion that one should 'respect their elders.' Using conservative Protestant affiliation as a proxy for Southern culture, this study also examines the relationship between Southern culture and homicide of the elderly. Findings show that Southern culture as reflected in conservative Protestant affiliation does not insulate the elderly from victimization.  相似文献

This research note explores a limit in the principle of confidentiality, demonstrating how informants' connected relationships can lead to impaired or diminished autonomy. Insiders may recognize what other insiders have said to a researcher in a private interview. Internal confidentiality is distinct from external confidentiality, which assures protection against identification by those who were not subjects of the research.  相似文献

For quite a few years the two authors have been engaging in dialogues about management issues. Using as a model Plato's dialogues between Socrates and his various students, we have tried to clarify the nature of a concept by asking questions and thinking carefully about the answers. We disagree about many things, but agree that we respect each other's opinions, and can clarify our own viewpoints by debating them respectfully with another. For this dialogue, we decided to focus on the question of the scale of business operations. One of us has a particular preference for small scale enterprise, and for the localisation of the economy, because he believes that the giganticism of corporations is behind many of the problems we face today. As you will see, the other protagonist disagrees, arguing instead that other issues than scale are at the root of why some businesses do bad things.  相似文献

The Best Linear Unbiased Predictor (BLUP) in mixed models is a function of the variance components and they are estimated using maximum likelihood (ML) or restricted ML methods. Nonconvergence of BLUP would occur due to a drawback of the standard likelihood-based approaches. In such situations, ML and REML either do not provide any BLUPs or all become equal. To overcome this drawback, we provide a generalized estimate (GE) of BLUP that does not suffer from the problem of negative or zero variance components, and compare its performance against the ML and REML estimates of BLUP. Simulated and published data are used to compare BLUP.  相似文献

We have reviewed disaster management research papers published in major operations management, management science, operations research, supply chain management and transportation/logistics journals. In reviewing these studies, our objective is to assess and present the macro level “architectural blue print” of disaster management research with the hope that it will attract new researchers and motivate established researchers to contribute to this important field. The secondary objective is to bring this disaster research to the attention of disaster administrators so that disasters are managed more efficiently and more effectively. We have mapped the disaster management research on the following five attributes of a disaster: (1) Disaster Management Function (decision‐making process, prevention and mitigation, evacuation, humanitarian logistics, casualty management, and recovery and restoration), (2) Time of Disaster (before, during and after), (3) Type of Disaster (accidents, earthquakes, floods, hurricanes, landslides, terrorism and wildfires etc.), (4) Data Type (Field and Archival data, Real data and Hypothetical data), and (5) Data Analysis Technique (bidding models, decision analysis, expert systems, fuzzy system analysis, game theory, heuristics, mathematical programming, network flow models, queueing theory, simulation and statistical analysis). We have done cross tabulations of data among these five parameters to gain greater insights into disaster research. Recommendations for future research are provided.  相似文献

Considerable public health literature focuses on relationships between problematic human characteristics (e.g., psychopathology) and unhealthy behaviors. A recent movement termed positive psychology emphasizes the advantages of assessing relationships between human strengths (e.g., altruism) and beneficial health behaviors. The present study assessed social responsibility, an orientation to help or protect others even when there is nothing to be gained as an individual, and its relationship to HIV-relevant behaviors. In our sample of 350 men who have sex with men (MSM), social responsibility was negatively correlated with substance use and HIV risk behaviors. Men who had been tested for HIV and knew their HIV status—a behavior that helps men protect their partners but does not protect themselves from the virus—also scored higher in social responsibility. Interventions designed to reduce HIV risk behavior in MSM may benefit from efforts to promote human strengths.  相似文献

The impetus towards basing practice and policy decisions moreexplicitly on sound research requires tools to facilitate thesystematic appraisal of the quality of research encompassinga diverse range of methods and designs. Five exemplar toolswere developed and assessed in terms of their usefulness inselecting studies for inclusion in a systematic review. Thewidely used ‘hierarchy of evidence’ was adaptedand used to appraise internal validity. Four tools were thendeveloped to appraise the external validity dimensions of generalizability(two scales) and methods of data collection (two scales). Methodsof combining the scores generated by each tool were explored.Qualitative and quantitative studies were appraised, not separatedinto two spheres but by using complementary tools developedto appraise different aspects of rigour. There was a high levelof agreement between researchers in applying the tools to twenty-twostudies on decision making by professionals about the long-termcare of older people. The scales for internal validity and generalizabilitydiscriminated between the qualities of studies appropriately.The two tools to appraise data collection gave diverse results.Excluding studies that scored in the lowest category on anyscale appeared to be the scoring system that was most justifiable.This approach is presented to stimulate debate about the practicalapplication of the evidence-based initiative to social workand social care. This study may assist in developing clearerdefinitions and common language about appraising rigour thatshould further the process of selecting robust research forsynthesis to inform practice and policy decisions.  相似文献
