A series of experiments shows (1) that people are significantlymore likely to select the middle response alternative on anissue when it is explicitly offered to them as part of the questionthan when it is omitted; (2) that merely mentioning that thereis a middle alternative, in the preface to the question, makesit more likely that respondents will select it, even thoughit is not offered to them as an explicit choice; (3) that theorder in which the middle alternative is presented in the question—inthe middle or last position—can make a significant differencein the results, but that a "recency bias" does not occur invariably,or consistently; and (4) that people who select a middle responsealternative when it is offered would not necessarily answerthe question in the same way as other respondents if forcedto choose sides on the issue. 相似文献

How do firm-specific, demand-related factors influence the relationship between intra-industry diversification (IID) and performance? Recent findings regarding the performance effects of IID depict a complex picture with curvilinear relationships and several contingencies. However, firm-specific contingencies on the demand side have remained unexplored. We analyze how IID relates to firm performance (market share) in the German automotive industry using panel data between 1999 and 2008. We specifically focus on a firm's high-quality brand image as a demand-side contingency. We find support for our hypotheses of complex curvilinear relationships as well as for moderating effects of brand quality. Our results have significant theoretical implications for the IID literature. 相似文献

Research on presenteeism has largely focused on its prevalence, determinants and consequences on the health of both employees and organizations. To date, few studies have examined the influence of presenteeism on workers’ attitudinal and motivational responses. Based on the Effort–Recovery Theory, this study evaluates the mediating effect of work engagement in the relationship between presenteeism and job satisfaction. Building on previous work, this study also proposes to consider perceived organizational support as a moderator of the work engagement–job satisfaction relationship. Presented in the form of a mediated moderation model, the results of bootstrapped regression analyses show three main results. First, presenteeism is negatively associated with work engagement and job satisfaction. Secondly, work engagement is one of the factors through which presenteeism influences job satisfaction. Thirdly, perceived organizational support moderates the association between work engagement and job satisfaction so that, at a low level of work engagement, feeling supported by the organization makes a difference on job satisfaction. Overall, this research is part of the limited number of studies that have focused on the interplay existing between presenteeism and its consequences in terms of job attitudes. 相似文献

RESPONSE-TIME MEASUREMENT IN SURVEY RESEARCH A METHOD FOR CATI AND A NEW LOOK AT NONATTITUDES 总被引:1,自引:0,他引:1
The paper introduces a methodology for measuring accuratelythe time it takes respondents to answer questions in computer-assistedtelephone surveys. The methodology, which is completely invisibleto respondents, comprises a computer "clock," capable of timingresponses with millisecond accuracy, and a "voice-key" thatconverts sounds emitted by respondents into signals capableof triggering the computer clock. Response times to questionson a range of attitude questions, including stable and unstableattitudes, were measured. The results revealed orderly normsin the latencies associated with various types of survey questions.The latencies associated with the expression of stable and unstableattitudes are discussed in the context of the notion of "nonattitudes"and shed new light on this controversial thesis. Overall, ourresults demonstrate that response latencies can be measuredprecisely and reliably in telephone surveys and that the datafrom such measurement open new windows on the cognitive dynamicsof survey responses. 相似文献

74 labor migrant families from various socioeconomic classes in Amman, Jordan were interviewed to examine changes in relationships among family members, extended family, and neighbors and their concerns about economic stability in the host country, Jordan, and the world market. Another purpose was to determine how current migration policies of the Arab oil-producing countries which prohibit labor migrants from bringing their families to the host country affect labor migration among families. The families consisted of either those who did or did not accompany the labor migrant. Overall labor migration affected unaccompanied families more than accompanied families, e.g., only 19% of the unaccompanied families reported increased family unity compared with 56% of accompanied families. Problems within unaccompanied families increased in 43% of the cases but in only 6% of the accompanied families. Many of these problems resulted in children dropping out of school which reflected the control fathers had within the family, separation, or divorce. Yet labor migration reduced family ties with extended family members and neighbors almost equally for both groups. Accompanied families were not as concerned about economic stability in Jordan as unaccompanied families (38% vs. 50%). Perhaps these families tended not to invest remittances received from the labor migrants working in Arab oil-producing countries in Jordan. Both groups were quite concerned about the economic stability in the host countries (66% and 72%, respectively) and the world market (59% and 62%, respectively), however. Since family unity suffers when families do not accompany labor migrants, it is suggested that oil-producing nations that depend on foreign labor should guarantee family unity as a human right. 相似文献

The problems that people experience in social roles can be regarded as either causes or consequences of psychological symptoms. To reflect one of these possibilities, Pearlin et al. (1981) developed measures of "role strains" which are considered sources of psychopathology. To reflect the other position, Dohrenwend et al. (1981) constructed measures of "role functioning" which are seen as consequences of psychopathology. We show that the measures developed by these two teams of investigators are similar in content and show substantial empirical overlap despite the different meanings attributed to them. In an effort to understand whether these highly correlated measures assess, "role strain" or "role functioning," we conduct an exploratory analysis of marital and housework role problems, using a small panel sample of New York City residents. Specifically, we use instrumental variables to identify reciprocal effects between psychological distress and each role area. We find that the relationship between housework role problems and distress is more consistent with Pearlin et al.'s interpretation, whereas the relationship between marital problems and distress is more consistent with that of Dohrenwend et al. Investigators interested in measuring either role strain or role functioning must bear in mind the strong possibility of contamination from the other construct. 相似文献

Originally presented to the Society of Home Health Care Management of the American College of Physician Executives at its November 16, 1993, meeting in Tucson, Ariz., the program described in this article was the winner of the College's 1994 Innovations Award in Medical Quality Management, sponsored by Merck Sharp & Dohme. The program shows the potential of case management for both improvement in the quality of care and containment of costs for a managed care population with a substantial Medicaid segment. This article is part of a continuing series on innovative programs in home health care. 相似文献

The following article is one of a series that deal with the provision of health care services around the world. Other countries in the series include Germany, Italy, Japan, Mexico, the Netherlands, and the United States. Countries scheduled for coverage in the series include Austria, France, Singapore, Spain, and the United Kingdom. The countries are described using a grid of characteristics so that comparisons may be made more easily. All of the analyses, along with further comparative data, will be gathered into a freestanding book to be published later in the year. Dr. Mendoza serves as editor for the project. 相似文献
