The Interplay between Online and Offline Explorations of Identity,Relationships, and Sex: A Mixed-Methods Study with LGBT Youth

Although the Internet is commonly used by lesbian, gay, bisexual, and transgender (LGBT) youth to explore aspects of sexual health, little is known about how this usage relates to offline explorations and experiences. This study used a mixed-methods approach to investigate the interplay between online and offline explorations of multiple dimensions of sexual health, which include sexually transmitted infections, sexual identities, romantic relationships, and sexual behaviors. A diverse community sample of 32 LGBT youth (ages 16–24) completed semi-structured interviews, which were transcribed and then qualitatively coded to identify themes. Results indicated that, although many participants evaluated online sexual health resources with caution, they frequently used the Internet to compensate for perceived limitations in offline resources and relationships. Some participants turned to the Internet to find friends and romantic partners, citing the relative difficulty of establishing offline contact with LGBT peers. Further, participants perceived the Internet as an efficient way to discover offline LGBT events and services relevant to sexual health. These results suggest that LGBT youth are motivated to fill gaps in their offline sexual health resources (e.g., books and personal communications) with online information. The Internet is a setting that can be harnessed to provide support for the successful development of sexual health.     

《破产法》第42条涉不当得利条款解释论

只有德国和受到德国影响的若干国家和地区在破产法中规定了不当得利之债优先受偿。德国法确立这一规则是因其特有的物权行为理论,不当得利之债优先受偿的学理解释与物权行为理论紧密相关。《日本破产法》受德国影响规定了相同规则,但其民法学理并不认可物权行为理论,因而另辟蹊径基于破产财团的独立性对该规则予以解释。我国《破产法》亦规定了该规则,但对其学理背景欠缺了解,存在立法论上的缺陷,应籍由解释论予以弥补。

Immutability, science, and legislative debate over gay, lesbian and bisexual rights

Many gay rights advocates argued in the 1990s that scientific research claiming that sexual orientation is immutable should contribute to gaining civil rights for gays, lesbians and bisexuals. This paper analyzes ten legislative debates that took place at the local, state and federal levels over whether to adopt antidiscrimination laws, before and after the research was published. We hypothesize that if the research has had the impacts hoped for by gay rights supporters, then debates over gay rights should reflect certain changes consistent with such impacts. Although discussion of the origins of sexual orientation among legislators rose in the aftermath of the studies, we fail to find that the science had a major impact on the debate strategies pursued by either pro- or antigay rights legislators. Whether sexual orientation is immutable or a choice has not been a central claim of the two sides in the debate. Gay rights opponents even appear somewhat more willing to assert that sexual orientation is a choice after the studies than before. Furthermore, when the proponents of gay rights assert the immutability argument, they are as likely as not to invoke the cultural authority of science. We explain these outcomes by showing why the immutability issue is not of central relevance to most legislators or necessary for either side's key arguments. We also show that the scientific evidence merely supplemented a large amount of anecdotal information that legislators already possessed that spoke to the origins of sexual orientation.

Sample size estimation for a two-group comparison of repeated count outcomes using GEE

Randomized clinical trials with count measurements as the primary outcome are common in various medical areas such as seizure counts in epilepsy trials, or relapse counts in multiple sclerosis trials. Controlled clinical trials frequently use a conventional parallel-group design that assigns subjects randomly to one of two treatment groups and repeatedly evaluates them at baseline and intervals across a treatment period of a fixed duration. The primary interest is to compare the rates of change between treatment groups. Generalized estimating equations (GEEs) have been widely used to compare rates of change between treatment groups because of its robustness to misspecification of the true correlation structure. In this paper, we derive a sample size formula for comparing the rates of change between two groups in a repeatedly measured count outcome using GEE. The sample size formula incorporates general missing patterns such as independent missing and monotone missing, and general correlation structures such as AR(1) and compound symmetry (CS). The performance of the sample size formula is evaluated through simulation studies. Sample size estimation is illustrated by a clinical trial example from epilepsy.
