Human beings have a dualistic relationship with the environment, being subject to physical and biological limits and yet being unique in the capacity for culture and symbolic communication. Sociology reflects this context and adds another dualism, drawing heavily from the concepts and perspectives of biological ecology, but reacting almost violently against "reductionism" of any sort, specifically including social Darwinism and environmental determinism. During much of the twentieth century, the predominant trend within sociology was for scholars to downplay or even ignore the importance of the environment, particularly in the United States. This trend was ultimately counterbalanced by sociological responses to the environmental movement of the late 1960s and early 1970s and by the efforts of selected sociologists-particulady Riley Dunlap and William Catton-who helped bring together the field of "environmental sociology." Given the finite nature of many natural resources and the ways in which human activities depend upon and affect the environment, the field of environmental sociology is likely to be an increasingly important one in the years to come.  相似文献

Two studies examined the effects of attractiveness of voice and physical appearance on impressions of personality. Subject-senders were videotaped as they read a standard-content text (Study 1) or randomly selected texts (Study 2). Judges rated the senders' vocal attractiveness from the auditory portion of the tape and their physical attractiveness from the visual portion of the tape. Other judges rated the senders' personality on the basis of their voice, face, or face plus voice. Senders with more attractive voices were rated more favorably in both the voice and face plus voice conditions; senders with more attractive faces were rated more favorably in both the face and face plus voice conditions. The effects of both vocal and physical attractiveness were more pronounced in the single channels (voice condition and face condition, respectively) than in the multiple channel (face plus voice condition). Possible antecedents and consequences of the vocal attractiveness stereotype are discussed. p]Her voice was ever soft, gentle, and low, an excellent thing in woman.Shakespeare (King Lear, Act V, Sc. 3)This research was supported in part by National Institute Mental Health Grant RO1 MH40498-01A2.

Legal regulation of the labor contract is central to American policy formation. This study analyzes the reasons for the passage of federal labor laws that governed workplace activity in the United States from 1897 to 1980. The dependent variable includes all major federal statutes that are favorable or detrimental to labor. Two theories are considered: a mass disruption approach and a party control perspective. Qualitative comparative analysis is used to assess the utility of both theories. For the pro-labor laws, the findings show partial support for both models. The theories are better at explaining reform prior to rather than after World War II. An explanation is presented for this temporal break. For the antilabor laws, the results are inconclusive due to the small sample size. An alternative account is offered that focuses on policy making under divided government. This research suggests analyzing the interaction of economic, class, and political variables and using larger sample research designs as guidelines for future investigation.  相似文献

The authors consider a formulation of penalized likelihood regression that is sufficiently general to cover canonical and noncanonical links for exponential families as well as accelerated life models with censored survival data. They present an asymptotic analysis of convergence rates to justify a simple approach to the lower‐dimensional approximation of the estimates. Such an approximation allows for much faster numerical calculation, paving the way to the development of algorithms that scale well with large data sets.  相似文献

This article draws on a household survey of giving and volunteering undertaken as part of the Giving Australia project to explore the relationship between religion and the giving behaviour of adult Australians. We find that people who identify themselves as having a religion are more likely to give and to give more on average than people who do not but that this relationship is produced by a subset of this group; namely, people who regularly attend religious services. Indeed, the likelihood of giving and average amounts given by givers over a year increase with levels of attendance at religious services. The relationship holds even after allowing for other factors that affect the likelihood of a person giving and the amount given. It also holds for giving to nonreligious causes (ie when giving to religion is omitted). However, when we also omit giving to charities and look at giving to civic causes alone we find that the frequency of attendance at religious services has an ambiguous relationship with giving. A suggestion in overseas literature that it is participation in religious groups, rather than attendance at religious services that is associated with giving is not supported.  相似文献

The linkages between self‐regulation in childhood, risk proneness in early adolescence, and risky sexual behavior in mid‐adolescence were examined in a cohort of children (N=518) from the National Longitudinal Survey of Youth. The possible mediating role of two early adolescent variables (substance use and negative peer pressure) was also examined. Self‐regulation was assessed by maternal report at ages 8–9, and risk proneness, comprising aspects of sensation seeking and decision making, was assessed by adolescent self‐report at ages 12–13. Structural equation models predicting risky sexual behavior at ages 16–17 indicated that self‐regulation operated partly through early adolescent substance use, whereas risk proneness operated through early adolescent substance use and negative peer pressure. The overall model did not differ significantly for boys and girls, although there were gender differences in the strength of particular paths. These long‐term longitudinal results support the importance of early self‐regulation and risk proneness in setting the stage for adolescent sexual risk taking and implicate substance use and negative peer pressure as processes through which risk proneness and poor self‐regulation lead to risky sexual behavior.  相似文献

Recent discussions of school choice have revived arguments thatthe decentralization of governing institutions can enhance thequality of public services by increasing the participation ofintended beneficiaries in the production of those services.We use data from the Schools and Staffing Survey to examinethe extent to which the decentralization of authority to charterschools induces parents to become more involved in their children'sschools. We find that parents are indeed more involved in charterschools than in observationally similar public schools, especiallyin urban elementary and middle schools. Although we find thatthis difference is partly attributable to measurable institutionaland organizational factors, we also find that charter schoolstend to be established in areas with above-average proportionsof involved parents, and we find suggestive evidence that, withinthose areas, it is the more involved parents who tend to selectinto charter schools. Thus, while the institutional characteristicsof charter schools do appear to induce parents to become moreinvolved in their children's schools, such characteristics areonly part of the explanation for the greater parental involvementin charter schools than in traditional public schools.  相似文献

Behavioral and electrophysiological evidence suggests a gradual, experience‐dependent specialization of cortical face processing systems that takes place largely in the 1st year of life. To further investigate these findings, event‐related potentials (ERPs) were collected from typically developing 9‐month‐old infants presented with pictures of familiar and unfamiliar monkey or human faces in 2 different orientations. Analyses revealed differential processing across changes in monkey and human faces. The N290 was greater for familiar compared to unfamiliar faces, regardless of species or orientation. In contrast, the P400 to unfamiliar faces was greater than to familiar faces, but only for the monkey condition. The P400 to human faces differentiated the orientation of both familiar and unfamiliar faces. These results suggest more specific processing of human compared to monkey faces in 9‐month‐olds.  相似文献
