负面评价恐惧与大学生网络过度使用的关系：社交焦虑和自我控制的中介作用

本研究以864名大学生为被试,探讨负面评价恐惧与网络过度使用的关系以及社交焦虑和自我控制在这一关系中的中介作用。结果发现：（1）负面评价恐惧与社交焦虑和网络过度使用之间均呈显著正相关,与自我控制存在显著负相关;（2）负面评价恐惧通过社交焦虑和自我控制的中介作用对网络过度使用产生影响,这一中介作用包含了三条路径：社交焦虑和自我控制的单独中介作用以及社交焦虑-自我控制的序列中介作用。这一结论有助于促进对大学生网络过度使用的干预与预防。     

Risk-taking increases under boredom

We examined if boredom is associated with risk-taking. Although this association has frequently been postulated, it has rarely been tested, and the evidence has thus far been rather indirect and speculative. We conducted three studies to test this association more systematically. In Study 1, people high in boredom proneness reported greater risk-taking across financial, ethical, recreational, and health or safety domains. In Study 2, over a series of risky decisions, risk-taking increased in tandem with state boredom. Consistently, in Study 3, people who felt more bored were more likely to choose risky gambles. Furthermore, while dispositional self-control predicted lower risk-taking, state boredom nullified this association, suggesting that elevated risk-taking might be attributed the erosion of self-control under boredom. Our findings establish via direct empirical tests that boredom is associated with making riskier decisions.     

父母严厉管教与儿童问题行为的关系:儿童自我控制的中介作用

为探讨父母严厉管教、儿童自我控制与儿童问题行为间的关系,采用中文版亲子冲突解决策略量表、社会技能评定量表和儿童行为核查量表对济南市两所公立学校的1097名小学四到六年级儿童及其父母双亲进行测查。结果发现：（1）父母心理攻击和体罚与儿童自我控制均呈显著负相关,与儿童内化和外化问题行为均呈显著正相关,儿童自我控制与其内化和外化问题行为均呈显著负相关;（2）父亲心理攻击可以显著正向预测儿童内化和外化问题行为,母亲体罚可以显著正向预测儿童外化问题行为;（3）儿童自我控制在父亲心理攻击和母亲体罚与儿童内外化问题行为之间起中介作用,在母亲心理攻击和父亲体罚与儿童内外化问题行为关系间的中介作用不显著,中介作用模型不存在显著的儿童性别差异。综上,本研究发现父母严厉管教不仅直接影响儿童的内外化问题行为,而且会通过降低儿童自我控制水平间接导致儿童问题行为的增多。     

Testing Measurement Invariance of the Dark Triad Dirty Dozen in a Belgian Adult Sample

The Dirty Dozen (Jonason & Webster, 2010) is a frequently used concise version of the Dark Triad to measure three socially aversive personality traits: Machiavellianism, psychopathy and, narcissism. The present study has examined measurement invariance in a sample of Belgian adults. The present study aims to assess measurement invariance of the Dutch version of the Dirty Dozen measure across gender in a large city-based representative adult sample in Belgium (N = 1587). Multi-group first-order confirmatory factor analysis for categorical indicators was utilized. In addition, unique associations between Dirty Dozen traits, trait self-control and, acceptance of illegitimate norms were examined in a series of structural equation models. Results indicated that the internal consistency of the Dirty Dozen subscales was good for Machiavellianism (α = 0.80) and narcissism (α = 0.80), but modest for psychopathy (α = 0.64). The hypothesized three correlated factors model with separate factors for Machiavellianism, psychopathy and, narcissism provided a poor fit for men and women. Invariance testing across gender showed evidence for weak invariance only, indicating that the underlying latent factors are measured the same way with the same metric in the two populations. However, we were not able to establish strong measurement invariance. Observed group differences should be interpreted with caution. Furthermore, Machiavellianism and psychopathy were strongly associated with trait self-control in both men and women. Strong correlations were found between acceptance of illegitimate norms and Dirty Dozen traits, Machiavellianism and, psychopathy, but not with narcissism.     

What We Owe to the Global Poor

This essay defends an account of the duties to the global poor that is informed by the empirical question of what makes countries rich or poor, and that tends to be broadly in agreement with John Rawlss account in The Law of Peoples. I begin by introducing the debate about the sources of growth and explore its implications for duties towards the poor. Next I explore whether (and deny that) there are any further-reaching duties towards the poor. Finally, I ask about the moral foundations for the duties to the poor of the sort that earlier parts argue there are.     

Do Patriotic Ties Limit Global Justice Duties?

Some theorists who accept the existence of global justice duties to alleviate the condition of distant needy strangers hold that these duties are significantly constrained by special ties to fellow countrymen. The patriotic priority thesis holds that morality requires the members of each nation-state to give priority to helping needy fellow compatriots over more needy distant strangers. Three arguments for constraint and patriotic priority are examined in this essay: an argument from fair play, one from coercion, another from coercion and autonomy. Under scrutiny, none of these arguments qualifies as successful.     

Global Inequality and International Institutions

This article considers the links between international institutions and global economic justice: how international institutions might be morally important; how they have changed; and at what those changes imply for justice. The institutional structure of international society has evolved in ways that help to undercut the arguments of those who take a restrictionist position towards global economic justice. There is now a denser and more integrated network of shared institutions and practices within which social expectations of global justice and injustice have become more securely established. But, at the same time, our major international social institutions continue to constitute a deformed political order. This combination of density and deformity shapes how we should think about international justice in general and has important implications for the scope, character, and modalities of global economic justice. Having laid out a view of normative development and where it leads, the article then examines why international distributive justice remains so marginal to current practice.     

Heat and Violence

The heat hypothesis states that hot temperatures can increase aggressive motives and behaviors. Although alternative explanations occasionally account for some portion of the observed increases in aggression when temperatures are high, none are sufficient to account for most such heat effects. Hot temperatures increase aggression by directly increasing feelings of hostility and indirectly increasing aggressive thoughts. Results show that global warming trends may well increase violent-crime rates. Better climate controls in many institutional settings (e.g., prisons, schools, the workplace) may reduce aggression-related problems in those settings.     

A global optimization approach for generating efficient points for multiobjective concave fractional programs

In this article, we present a global optimization approach for generating efficient points for multiobjective concave fractional programming problems. The main work of the approach involves solving an instance of a concave multiplicative fractional program (W̄). Problem (W̄) is a global optimization problem for which no known algorithms are available. Therefore, to render the approach practical, we develop and validate a branch and bound algorithm for globally solving problem (W̄). To illustrate the performance of the global optimization approach, we use it to generate efficient points for a sample multiobjective concave fractional program.
