Latent roots of random data correlation matrices with squared multiple correlations on the diagonal: A monte carlo study

In order to make the parallel analysis criterion for determining the number of factors easy to use, regression equations for predicting the logarithms of the latent roots of random correlation matrices, with squared multiple correlations on the diagonal, are presented. The correlation matrices were derived from distributions of normally distributed random numbers. The independent variables are log (N–1) and log {[n(n–1)/2]–[(i–1)n]}, whereN is the number of observations;n, the number of variables; andi, the ordinal position of the eigenvalue. The results were excellent, with multiple correlation coefficients ranging from .9948 to .9992.This research was supported by the Office of Naval Research under Contract N00014-67-A-0305-0012, Lloyd G.

The sex by race interaction in cognitive measures

Data consisting of 79 cognitive measures from Project TALENT for 100,000 white and black high school students have been analyzed for possible race by sex interactions. Control variables included geographical area, grade in high school, and socio-economic class. Race by sex interactions are largest when socioeconomic class is controlled and are highly related to the size of the main effect of sex as well. White boys and girls differ more than black boys and girls whether the overall sex difference favors males or females. Sex by grade and, to a lesser extent, sex by area interactions were also moderately large and consistent with the size of the main effect of sex. Since there are no consistent relationships with other main effects, and since the measures producing sex differences also tend to produce the interactions, it is concluded that sex differences and the interactions with sex share the same causes. Differences between these results and those of Jensen are also discussed.     

药学评估思维在住院患者药学干预中的应用

临床药师在药学查房工作中建立药学评价和药师干预评估思维,为药学查房工作提供参考。临床药师对住院患者的治疗全过程做出药学评估,包括对初始治疗方案的合理性、风险、矛盾的评估,治疗过程中对病情变化、治疗方案变化的评估,出院时对出院后病情防复发、防进展、防恶化以及如何康复的评估。临床药师应将药学评估思维运用到住院患者治疗过程中,利用药学专业优势,参与临床药物治疗,在临床治疗团队中真正发挥作用,能促进患者合理用药。

Why Higher Working Memory Capacity May Help You Learn: Sampling,Search, and Degrees of Approximation

Algorithms for approximate Bayesian inference, such as those based on sampling (i.e., Monte Carlo methods), provide a natural source of models of how people may deal with uncertainty with limited cognitive resources. Here, we consider the idea that individual differences in working memory capacity (WMC) may be usefully modeled in terms of the number of samples, or “particles,” available to perform inference. To test this idea, we focus on two recent experiments that report positive associations between WMC and two distinct aspects of categorization performance: the ability to learn novel categories, and the ability to switch between different categorization strategies (“knowledge restructuring”). In favor of the idea of modeling WMC as a number of particles, we show that a single model can reproduce both experimental results by varying the number of particles—increasing the number of particles leads to both faster category learning and improved strategy‐switching. Furthermore, when we fit the model to individual participants, we found a positive association between WMC and best‐fit number of particles for strategy switching. However, no association between WMC and best‐fit number of particles was found for category learning. These results are discussed in the context of the general challenge of disentangling the contributions of different potential sources of behavioral variability.     

Better Never to Have Been Born

The pro‐life paradox, as I call it, begins with a single claim endorsed by many American Christians: infants and young children are innocent in the sight of God because they cannot yet take responsibility for their spiritual well‐being. With this in mind, I argue that pro‐life believers have unwittingly fallen victim to a theological paradox in which their attempts to save the earthly lives of unborn children make it theoretically possible for said children to die an eternal death. On the one hand, many Christians trust in an eventual spiritual reckoning where God will separate the “sheep” from the “goats” (see Matthew 25:31–46), ushering the former into heaven while damning the latter to hell. However, those who cannot yet repent and seek salvation are not blamed for their spiritual failings. If they die, they go to heaven because they are too young and intellectually immature to know any better. But if dead children are spiritually blameless, then abortion practitioners have perversely and paradoxically saved millions of unborn souls by removing human volition (and thus damnation itself) from the equation and by making it possible for the unborn to experience the joys of heaven without the temptations of earth.     

Heteronormativity and/as Violence: The “Sexing” of Gwen Araujo

This paper will examine the violence of heteronormativity: the violence that constitutes and regulates bodies according to normative notions of sex, gender, and sexuality. This violence, I will argue, requires more than a focus on gendered or sexualized physical harms of the kinds normally examined when studying violence against sexual minorities or women. Rather, it necessitates focusing on the multiple modalities through which heteronormativity performs its violence on, through, and against bodies and persons, including through the production of certain bodies and persons as inciting violence in their very being. To establish my argument, I explore the killing in 2002 of trans woman Gwen Araujo and the violence of the legal strategy (the trans panic defense) used in the legal trials that followed her killing. Both forms of violence, I suggest, operate in a similar way, albeit through different mechanisms, to maintain and extend the system of binary morphology that itself entails the perpetual violent materialization of sexed bodies.
