Recently, the leading position of telephone surveys as the majormode of data collection has been challenged. Telephone surveyssuffer from a growing nonresponse, partly due to the generalnonresponse trend for all surveys and partly due to changesin society and technology influencing contactability and willingnessto answer. One way to counteract the increasing nonresponseis the use of an advance letter. In mail and face-to-face surveys,advance letters have been proven effective. Based on the proveneffectiveness in face-to-face and mail surveys, survey handbooksadvise the use of advance letters in telephone surveys. Thisstudy reviews the evidence for this advice and presents a quantitativesummary of empirical studies on the effectiveness of advanceletters in raising the response rate for telephone surveys.The major conclusion is that advance letters are also an effectivetool in telephone surveys, with an average increase in responserate (RR1) from 58 percent (no letter) to 66 percent (advanceletter), and an average increase in cooperation rate (COOP1)from 64 percent (no letter) to 75 percent (advance letter). 相似文献

Social capital is broadly defined as the valueof social relationships. A substantial amount of work has beenconducted into the role of social capital, but little of ithas focused on Latin America and Peru in particular. Standardtools are often used to measure social capital in differentcultural settings. We argue that while there are common themes,the exact nature of social capital is dependent upon the specificnorms of behaviour, networks and organizations that characterizea given setting. Social capital is a multidimensional and culturallyspecific concept. The contribution that different organizationsand networks make to different aspects of social capital variesby setting (rural/urban), person involved (male/female), andover time, highlighting the need for culturally sensitive measures.Two approaches are used to describe the characteristics of socialcapital in Peru: a literature review of research on social capitalin Peru, and qualitative in-depth interviews with twenty respondentsfrom one rural and two urban areas of Peru. 相似文献

OBJECTIVE: In this exploratory study, the authors evaluated the impact of an elective college course on dieting levels, eating styles, and body image among college women. PARTICIPANTS: Participants were a convenience sample of 29 self-selected female students at a western university who were mostly white, normal-weight seniors with significant dieting experience. METHODS: The authors used valid and reliable instruments to collect data both before and after testing. An instructor conducted the program in an undergraduate course that met twice weekly for 15 weeks. Theory-based lessons focused on resisting media pressure, modifying dietary restraint, eating in response to hunger (intrinsic eating), and achieving healthy body image. Dependent variables included intrinsic eating, dieting involvement, emotional eating, body image, and self-esteem. RESULTS: A comparison of pretest and posttest scores identified significant improvements for most measures. CONCLUSIONS: A theory-driven elective course implemented within a college setting may improve women's eating styles and body image. 相似文献

The aim of this study was to study suicide risk in subjects exposed to mobbing, that is, systematic psychological harassment in the workplace. Such psychological harassment, unique to the workplace, threatens both the emotional well-being and professional ability of its victims. The items of the Minnesota Multiphasic Personality Inventory-2 (MMPI-2) that assess suicide risk were studied in 102 individuals who were exposed to mobbing. The results indicated that individuals exposed to mobbing had clear differences on the MMPI-2 from normative samples. In addition, those who appeared to be at risk for suicide differed in their scores from those not at risk. Implications for psychopathology and suicide preventions are discussed. 相似文献

The Russian Federation has come back on the international scene, in the past years, thanks to its economic expansion and its
political stability. The defence sector, a pillar of the Soviet regime, takes advantage of this situation and is receiving
increasing funds, although the fraction of the GDP remains constant. Some experts fear a renewed arms race and a new threat
for the world security. The analysis of the overall figures leads to a more moderate view. The situation of the Armed Forces
suffers from many problems and it is far from being dangerous for the world stability. The core of the Army, the personnel,
is in a terrible situation with a huge gap compared with other developed nations. In addition, Russia endures a demographic
collapse and it will be always more difficult to find capable arms that use the new generation armaments of the proclaimed
modernization plans.

Risk communications are an integral aspect of health education and promotion. However, the commonly used textual risk information is relatively difficult to understand for the average recipient. Consequently, researchers and health promoters have started to focus on so‐called decision aids, such as tables and graphs. Although tabular and graphical risk information more effectively communicate risks than textual risk information, the cognitive mechanisms responsible for this enhancement are unclear. This study aimed to examine two possible mechanisms (i.e., cognitive workload and attention). Cognitive workload (mean pupil size and peak pupil dilation) and attention directed to the risk information (viewing time, number of eye fixations, and eye fixation durations) were both measured in a between‐subjects experimental design. The results suggest that graphical risk information facilitates comprehension of that information because it attracts and holds attention for a longer period of time than textual risk information. Graphs are thus a valuable asset to risk communication practice for two reasons: first, they tend to attract attention and, second, when attended to, they elicit information extraction with relatively little cognitive effort, and finally result in better comprehension. 相似文献

Ethical leadership predicts important organizational outcomes such as decreased deviant and increased organizational citizenship behavior (OCB). We argued that due to the distinct nature of these two types of employee behaviors, ethical leadership decreases deviance in a linear manner (i.e., more ethical leadership leading to less deviance), but we expected ethical leadership to reveal a curvilinear relationship with respect to OCB. Specifically, we expected that, at lower levels, ethical leadership promotes OCB. However, at high levels, ethical leadership should lead to a decrease in these behaviors. We also examined a mechanism that explains this curvilinear pattern, that is, followers' perceptions of moral reproach. Our predictions were supported in three organizational field studies and an experiment. These findings offer a better understanding of the processes that underlie the workings of ethical leadership. They also imply a dilemma for organizations in which they face the choice between limiting deviant employee behavior and promoting OCB. 相似文献

Using the demand-control-support perspective on job stress, a Dutch translation of an adapted version of the Job Content Questionnaire (AJCQ) was administered to a large population ( N = 3638) of Flemish workers in a variety of jobs, together with the General Health Questionnaire, and a negative affectivity scale. Overall, the AJCQ was shown to be a solid measurement instrument as indicated by several estimated reliability indices and validity of the subscales. A factor analysis largely reproduced the a priori structure of the AJCQ. A short 10-item direct questioning procedure was constructed to measure the 10 subscales of the AJCQ and the results of this procedure were compared with the AJCQ in a subsample ( N = 660). The correlations with six criterion variables showed that single questions were equally predictive than the much longer version of the AJCQ. 相似文献
