Suicidality Among Gay and Bisexual Men in Taiwan: Its Relationships with Sexuality and Gender Role Characteristics,Homophobic Bullying Victimization,and Social Support

This study aimed to examine the associations of suicidality in emerging adulthood with time of coming out, gender role nonconformity, sexual orientation, traditional and cyber homophobic bullying victimization, and family and peer support during childhood in gay and bisexual men in Taiwan. The frequency of “experiencing suicide ideation” and “attempting suicide” in the past year among 500 gay or bisexual men was examined. The participants’ time of coming out, level of subjective masculinity, sexual orientation, experiences of traditional and cyber homophobic bullying victimization, and levels of family and peer support during childhood were also evaluated. In total, 31% (n = 155) of participants reported experiencing suicide ideation (n = 82) or attempting suicide (n = 73). Early coming out, traditional homophobic bullying victimization, and low family support during childhood increased the risk of suicidality in emerging adulthood; by contrast, family support did not moderate the association of early coming out or traditional bullying victimization with current suicidality. A high proportion of participants reported experiencing suicide ideation and attempt in emerging adulthood. Hence, effective suicide prevention is required for gay and bisexual men. Suicide prevention programs should consider time of coming out, traditional homophobic bullying victimization, and level of family support.     

A computer model of auditory stream segregation

A computer model is described which simulates some aspects of auditory stream segregation. The model emphasizes the explanatory power of simple physiological principles operating at a peripheral rather than a central level. The model consists of a multi-channel bandpass-filter bank with a “noisy” output and an attentional mechanism that responds selectively to the channel with the greatest activity. A “leaky integration” principle allows channel excitation to accumulate and dissipate over time. The model produces similar results to two experimental demonstrations of streaming phenomena, which are presented in detail. These results are discussed in terms of the “emergent properties” of a system governed by simple physiological principles. As such the model is contrasted with higher-level Gestalt explanations of the same phenomena while accepting that they may constitute complementary kinds of explanation.     

Log Data Analysis with ANFIS: A Fuzzy Neural Network Approach

This study explores the use of the Adaptive Neuro-Fuzzy Inference System (ANFIS), a neuro-fuzzy approach, to analyze the log data of technology-based assessments to extract relevant features of student problem-solving processes, and develop and refine a set of fuzzy logic rules that could be used to interpret student performance. The log data that record student response processes while solving a science simulation task were analyzed with ANFIS. Results indicate the ANFIS analysis could generate and refine a set of fuzzy rules that shed lights on the process of how students solve the simulation task. We conclude the article by discussing the advantages of combining human judgments with the learning capacity of ANFIS for log data analysis and outlining the limitations of the current study and areas of future research.     

Understanding choice utterances

When individuals offer choices, they intend them to be mandatory (requiring action) or permissive (not requiring action), and they intend them to be open (allowing the choice of both options) or closed (not allowing the choice of both options). In two studies subjects were presented with sets of syntactically equivalent disjunctive sentences with varying content designed to represent four patterns of permitted choice. The research indicates that individuals distinguish four distinct uses of “or” in deontic contexts, and that individuals more often judge choices as mandatory than permissive. The research also compared responses to questions about choice giver intent and receiver choice. The data indicate that when judging intent, individuals are inclined to understand some choices to be permissive. However, when judging what action they might take as choice receiver, subjects tend to regard action to be mandatory. It appears that although people have some facility in assessing a permission giver's intent, they often apply a more restrictive rule to themselves than is required by the choice giver.
