The Associations of Race/Ethnicity and Suicidal Ideation among College Students: A Latent Class Analysis Examining Precipitating Events and Disclosure Patterns

The aim of this paper was to examine precipitating events for suicidal ideation and how these experiences relate to disclosure in a diverse sample of college students were examined. Among non‐Hispanic White students, relationship/academic problems were most associated with ideation. A romantic break‐up increased the odds of getting help. Among racial/ethnic minority students, family/academic problems were most associated with ideation and students who reported multiple events were less likely to get help compared with those not reporting events. Future research should examine the reasons for interpersonal conflict among this high‐risk group and their attitudes about help‐seeking, and identify cultural norms associated with disclosure.     

Differentiating Suicide Attempters from Suicide Ideators: A Critical Frontier for Suicidology Research

Most individuals who consider suicide do not make suicide attempts. It is therefore critical to identify which suicide ideators are at greatest risk of acting on their thoughts. However, few seminal theories of suicide address which ideators go on to make attempts. In addition, perhaps surprisingly, most oft‐cited risk factors for suicide—such as psychiatric disorders, depression, hopelessness, and even impulsivity—distinguish poorly between those who attempt suicide and those who only consider suicide. This special section of Suicide and Life‐Threatening Behavior serves to highlight this knowledge gap and provide new data on differences (and similarities) between suicide attempters and suicide ideators.     

嵌套词汉字位置加工的亚词边界效应

使用眼动追踪技术，采用边界范式，考察了三字嵌套词的汉字位置加工是否存在亚词边界效应。实验以三字前嵌套词（如“历史系”）和三字后嵌套词（如“核技术”）为靶子，对次字和尾字进行操纵（相同、转置和替换）。结果发现：对于前嵌套词，靶子的注视时间在替换条件显著长于转置条件，相同条件和转置条件差异不显著；对于后嵌套词，靶子的注视时间在转置条件显著长于相同条件，替换条件和转置条件差异不显著。结果表明：跨亚词边界汉字转置不影响词汇识别，而亚词首字转置干扰词汇识别。     

大衍之数“五十有五”说补证

当代学者已从多方面论证了"大衍之数"当为"五十有五",有理有据,但尚有补证的空间。汉唐时期关于"五十有五"说的文献证据以及清人程廷祚、徐灏等人关于"五十有五"说的论证,则可以更好地补证大衍之数"五十有五"说的合理性。换言之,则可以进一步论证:通行本《系辞》所云"大衍之数五十,其用四十有九"的确存在"脱误"问题,大衍筮法从五十五根蓍草中所拿出的六根蓍草,恰好可以用来"布六爻之位",是为"自然之妙"。
