Many communities are developing civic computer networks to provide citizens with free access to local information resources and the Internet. However, most networks restrict both commercial speech and any language deemed “objectionable.”; Whether such broad discretionary power violates the First Amendment depends on whether the networks are state actors. An examination of one such network, Alachua Free‐Net, reveals a close symbiotic relationship between the network and several local government entities. Symbiotic relationships between the state and a private party in other contexts have been held by the courts to constitute state action. Thus, Alachua Free‐Net appears to be a state actor and must conform its speech restrictions to the requirements of the First Amendment. Moreover, whether state actors or not, civic computer networks such as Alachua Free‐Net should commit themselves to providing full First Amendment freedoms to their users.  相似文献

Results of the second year of a 3-year longitudinal study on children's body size estimations are reported. Participants were 216 male and female children age 6 through 13. Body size estimations were measured using a TV-video methodology. Three psychophysical procedures measured perceived body size, idealized size, and body dissatisfaction. Self-esteem, body esteem, birth order, number of siblings, and parents' socioeconomic status (SES) were measured. Children were accurate in estimating body size, with no gender, age, or ethnic differences. Individual estimations varied greatly over the 1-year test-retest interval. Children had a slight bias to report that their body size was distorted too wide. Both genders wanted to be thinner, with females wanting to be increasingly thinner as they became older. Females were also more dissatisfied with their body size. Taller and heavier children with high SES fathers wanted a thinner idealized body size. Taller, thinner children had less body size dissatisfaction. Children with a larger number of siblings who were one of the first born were more dissatisfied with their body size. Children who gained weight during the previous year without a concomitant growth in height were also more dissatisfied with their body and wanted to be thinner. Body size estimation is viewed as an important aspect of one's body image and is mediated by many different variables, each of which individually explains only a small part of the variance.  相似文献

As Taiwan transitions from an immigrant-sending to an immigrant-receiving country, it struggles to build an immigration bureaucracy while its status as a sovereign nation-state is not recognized by much of the international community. Taiwan's largest immigrant group, marital migrants from China, are perceived as posing the greatest challenges to border control due to longstanding political tensions between the two countries and governmental and societal suspicions about Chinese spouses' marital motives. Based on research conducted with immigration officials and during immigration interviews at the border, this article interrogates the status of ‘truth’ in official efforts to determine definitively immigrants' marital intentions. It analyzes such truth demands in relation to Taiwan's anxieties about its national standing and the ability of an immigration bureaucracy to generate ‘sovereignty effects’.  相似文献

Sexual minority (lesbian and gay, bisexual, mostly heterosexual) individuals are at an increased risk for hazardous drinking than heterosexual individuals, but little is known about the nature of the disparities as adolescents reach adulthood. We used four waves of a nationally representative data set, the National Longitudinal Study of Adolescent Health (Add Health), to examine disparities of hazardous drinking outcomes between sexual minority and heterosexual men and women from adolescence to young adulthood. Participants were 14–18 years old at the first assessment (N = 12,379; 53 % female) and 27–31 years old at the fourth assessment. At the fourth assessment, 13 % self-identified as sexual minority individuals, 16 % were Hispanic, and 36 % were of minority race, including primarily African Americans (60 %) and Asian Americans (18 %). There were clear hazardous drinking disparities between sexual minority individuals and heterosexual individuals over time. During adolescence, sexual minority individuals, particularly females, reported higher levels of hazardous drinking. As study participants reached adulthood, the magnitude of the hazardous drinking disparities increased among sexual minorities, sexual minority men in particular. Additional research is needed to better understand the developmental mechanisms that underlie the emerging sexual orientation related disparities of hazardous drinking in young adulthood.  相似文献
