Stokowski F 《Wiadomo?ci statystyczne (Warsaw, Poland : 1956)》1992,37(1):26-29
The concept of spatial demographic order is introduced and defined as the preferred spatial distribution of a given demographic variable. The results of a multivariate statistical analysis of demographic trends in rural and urban areas in Poland are presented to illustrate the convergence of such trends in the areas studied. The author concludes that the increasing similarity in demographic processes between rural and urban areas is due mainly to migration. 相似文献

The total fertility rate of women of childbearing age of Dongguan County in China has been decreasing gradually from 5.9 during the period following the liberation in 1949 to 2.05 in 1982. In order to encourage young couples to implement the policy of family planning consciously, the people's government of Dongguan county decided in July 1980 that all cadres and employees in county towns who received 1-child certificates would be exempted from house rent of 45 square meters from the time they get their certificates and would be allocated a living space of a 2-children family until their children reached age 16. It also stipulated that every couple could enjoy 1 month's holiday every year for 3 years and during the holiday, their salary, bonus and rate of attendance would not be affected. Because women bear less children today, they are relieved from heavy household chores and become the main working force in collective production. As a result, the development of town-run enterprises was stimulated and the total industrial output value of these enterprises increased. The average monthly salary of each female worker is about 100 yuan. In 1984, the average income per capita of the country rose to 649.2 yuan. The implementation of family planning work has eased the tension in the education field. Previously, because of the large number of school-age children in rural areas, teachers had to teach 2 classes. In the past 4 years, great emphasis was laid on intellectual investment. During this period, 2351 schools were built and several fundraising projects were implemented. Since 1981, more than 200 new running water projects were built, and new public services have been developed, including old age homes. 相似文献

Both published results from the 1930, 1947, 1960 and 1971 censuses and unpublished ones are used to examine the influence that religious denomination, socio-economic group and region exerted on the fertility of marriages contracted between 1876 and 1959. A theory formulated by Lesthaeghe and Wilson on the relation between modes of production and secularization and the pace of fertility decline in Western Europe offers — in combination with van Heek's views on the special position of Dutch Roman Catholicism — a starting point for an explanation of why the fertility decline of Roman Catholics, self-employed and agricultural labourers lagged behind. 相似文献

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

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
