The potential of online social networking data for augmenting the study of high-risk personal networks among young men who have sex with men at-risk for HIV

Capturing dynamics in high-risk personal networks is essential for preventing HIV transmission. Online social networking data offer incentive to augment traditional selfreported approaches for network enumeration. To explore what online networks reveal about dynamics among high-risk associates, we examine the relationship between egocentric confidant and sex networks and personal Facebook friendship networks of a cohort of young Black men who have sex with men. Although overlap exists between self-reported and Facebook associates, the stabilities of each were unrelated. Confidants who were also Facebook friends with a respondent were, however, more likely to be retained. Thus, Facebook networks contain stable confidants.     

波兰语义学派NSM理论对情感词汇的语义解释力

每种语言都为本民族提供了一套阐释范畴,并按照不同的认知图景使人们的情感体验概念化。这些认知图景又与特定语言的词汇范畴联系在一起,因而赋予了特定文化的价值、态度和意义。波兰语义学派的自然语义元语言(NSM)理论从跨语言和跨文化的视角来研究情感概念及其意义。通过梳理前人的有关论述,以自然语义元语言理论为框架,以普遍性语义基元为释义单位,探讨了NSM理论的化简释义方法及其对情感词汇的语义解释力,展示了应用NSM这一用途广泛的释义工具来准确地表征情感概念的意义。普遍的人类概念是构成人类理解情感概念的基石。基于60多个人类普遍概念的NSM研究方法,无疑将有助于我们更好地理解和把握不同文化的人类情感概念。     

Separation and Post‐Separation Parenting within Lesbian and Gay Co‐parenting (Guild Parented) Families

Gay men and lesbian women have a long history of jointly creating families and co‐parenting their children together. This qualitative study aims to explore the experiences of separation and post‐separation parenting within same‐sex parented families. This involved semi‐structured in‐depth interviews with 22 separated same‐sex parents in Adelaide, Melbourne, Sydney, Brisbane, and regional Victoria. An adaptive theory approach was used for the collection and analysis of the data. The paper explores data from a cohort of six participants who came from three different multi‐parent families who had experienced a separation – either their own, or that of other parents in their parenting group. The term ‘co‐parenting families’ was found to be confusing due to the different connotations within separation/divorce and same‐sex parent literature. Consequently, the term ‘guild parented families’ was created to describe these families. Participants from these multi‐parent families had very different experiences of family formation and separation compared to others within the wider separated same‐sex parent study. Separation of one or more of the parent couples within these families complicated their original plans and kinship ideals. Each of the families resolved this differently in their post‐separation arrangements. After separation, whole family narratives and/or the role of individual parents, were either questioned or revised as a way of resolving the complexity of their new kinship situation. Following separation, parents often relied on Western kinship norms that privilege biological kinship and the dual‐parent family to construct their post‐separation kinship arrangements. More awareness of families that begin with more than two parents is needed within separation research and amongst separation services and service providers.     

Sex differences in the development of mild cognitive impairment and probable Alzheimer’s disease as predicted by hippocampal volume or white matter hyperintensities

This study examined biological sex differences in the development of mild cognitive impairment (MCI) and probable Alzheimer’s disease (AD) development as predicted by changes in the hippocampus or white matter hyperintensities. A secondary data analysis of the National Alzheimer’s Coordinating Center Uniform Data Set was conducted. We selected samples of participants with normal cognition at baseline who progressed to MCI (n = 483) and those who progressed to probable AD (n = 211) to determine if hippocampal volume or white matter hyperintensities (WMH) at baseline predicted progression to probable AD or MCI and whether the rate of progression differed between men and women. The survival analyses indicated that changes in hippocampal volumes affected the progression to probable AD (HR = 0.535, 95% CI [0.300–0.953]) only among women. White men had an increased rate of progression to AD (HR = 4.396, CI [1.012–19.08]; HR = 4.665, 95% CI [1.072–20.29]) compared to men in other race and ethnic groups. Among women, increases in hippocampal volume ratio led to decreased rates of progressing to MCI (HR = 0.386, 95% CI [0.166–0.901]). Increased WMH among men led to faster progression to MCI (HR = 1.048. 95% CI [1.011–1.086]). Women and men who were older at baseline were more likely to progress to MCI. In addition, results from longitudinal analyses showed that women with a higher CDR global score, older age at baseline, or more disinhibition symptoms experienced higher odds of MCI development. Changes in hippocampal volumes affect the progression to or odds of probable AD (and MCI) more so among women than men, while changes in WMH affected the progression to MCI only among men.     

从认知视角看英汉词语的语义变化趋势

语言在很大程度上受思维习惯和文化内涵的影响.然而,在世界文化朝着多元化发展的进程中,不同文化间的频繁接触促进了文化的趋同,而文化的趋同又必然引起词语的语义变化.文章旨在通过词语的示例分析比较,探讨人类语言的共性和个性,从而证明英汉两种语言的词语语义随着文化的趋同所出现的同一变化趋势.     

从文化差异的角度浅议颜色词
