This study sought to desribe and compare commitment structures among lesbian and gay male living-together relationships, and to develop an instrument which would measure different dimensions of commitment among gay dyads without some heterosexual biases inherent in traditional measures of interpersonal commitment. Questionnaire data collected from 32 lesbians and 50 gay males who had lived together for at least six months were factor analyzed, yielding three factors: (1) intradyadic commitment, (2) extradyadic commitment, and (3) commitment-as-trust. On all three of these indices the lesbians scored somewhat higher than did the gay males, but in fact there were surprisingly few significant differences between the gay men and the lesbians. Suggestions in the data that lesbians report somewhat less social supports and are more concerned with couple boundary maintenance, whereas gay males report somewhat more jealousy and dependency, are discussed in terms of their implications for such relationships. 相似文献

Rainwater's assertion that blacks have low self-evaluations because they receive more negative evaluations from other blacks than whites receive from other whites is challenged here by reference to Heiss and Owens evidence that negative self evaluation among blacks is limited to work-related traits. Substantial support was found for our major hypotheses that, compared to whites, (1) blacks would report more negative evaluation of “most men” but not of “most women” (since the provider role is traditionally ascribed primarily to men), and (2) the more negative evaluation of “most men” by blacks would be limited to work-related traits. 相似文献

An attempt is made to establish primary integration as a major variable in explaining citizen involvement in political life. It is argued that a convincing case requires a demonstration that the variable is both empirically important and theoretically meaningful. The former is examined through data from a sample survey of an English city. Theoretical meaning is established through focussing upon the idea of sociable talk as a key factor in reality construction, including the construction of political events as a proximate world available for the interest and participation by the individual. 相似文献

This paper analyses the interrelation between the transport system and measures of resource consumption such as material and energy consumption over a 60-year period (1937–1997) in the UK. Non-motorized transport and time consumption for mobility are estimated in addition to conventional measures of transport. During the period analyzed, the UK population grew by 20% while transport of goods and persons increased more than threefold and material and energy consumption almost doubled. The transport intensity of domestic material input (DMI) doubled to 300 ton-kilometers (tkm) per ton of DMI while the transport intensity of domestic energy consumption (DEC) doubled to 20 tkm per gigajoule (GJ) of DEC. Thus, while the material and energy intensity of GDP declined significantly, a well-established trend in many advanced countries, the transport intensity of materials and energy consumption rose. These findings suggest a close link between transport, economic development, and long-term structural transformations. In the case of personal transport, a rebound effect was also observed: whereas the average speed of transport has greatly increased, the average number of hours per day devoted to personal transport has not declined. 相似文献

Crucial to the long-term contribution of immigration to a receiving country's population is the extent to which the immigrants reproduce themselves in subsequent, native-born generations. Using conventional projection methodologies, this fertility contribution may be poorly estimated primarily because of problems in projecting the number of immigrants who are at risk of childbearing. We propose an alternative method that obviates the need to project the number of immigrants by using the full sending-country birth cohort as the risk group to project their receiving-country childbearing. This "sending-country birth cohort" method is found to perform dramatically better than conventional methods when projecting to 1999 from base years both before and after the large increase in inflows of Mexican immigrants to the United States in the late 1980s. Projecting forward from 1999, we estimate a cumulative contribution of Mexican immigrant fertility from the 1980s to 2040 of 36 million births, including 25% to 50% more births after 1995 than are projected using conventional methods. 相似文献
