The enduring impact of violence against children

More than one billion children – half of all children in the world – are exposed to violence every year. The violence children are exposed to includes both direct experiences of physical, sexual, and emotional abuse, as well as indirectly witnessing violence in their homes, schools, and communities. What these various forms of violence share, based on a review of the literature, is their enduring potential for life-long consequences. These consequences include increases in the risks of injury, HIV, sexually transmitted infections, mental health problems, reproductive health problems, and non-communicable diseases, including cardiovascular disease, cancer, chronic lung disease, and diabetes. Studies addressing biologic underpinnings of such consequences demonstrate that violence-associated toxic stress may cause damage to the nervous, endocrine, circulatory, musculo-skeletal, reproductive, respiratory, and immune systems. Furthermore, rigorous economic evaluations suggest that costs associated with the consequences of violence against children exceed $120 billion in the U.S. and account for up to 3.5% of the GDP in sub-regions of East Asia. The expanding literature confirming the mechanisms of consequences and the associated costs of violence against children has been accompanied by growing evidence on effective approaches to prevention. Moreover, the expanding evidence on prevention has been accompanied by a growing determination on the part of global leaders to accelerate action. Thus, as part of the Post-2015 Sustainable Development agenda, the UN has issued a call-to-action: to eliminate violence against children. This unprecedented UN call may foster new investments, to fuel new progress for protecting children around the world from violence and its preventable consequences.     

组织中的变革担当：积极组织行为研究的新主题

变革担当是指员工自愿付出建设性努力来发起组织功能性变革,以便在自己的岗位、部门或组织情境中更加有效地开展工作。文章介绍了变革担当的概念、测量以及前因后效。其中前因包括个体因素（如前瞻性人格、组织支持感、积极情绪等）和情境因素（如工作自主性、管理开放性、创新氛围等）两大类,后效主要有工作绩效评价、工作态度和变革型领导知觉等。未来的研究需要进一步完善测量工具、考察组织外部因素的影响、检验影响后效的其他调节因素以及探讨领导者的变革担当行为。     

Don’t say that!

According to pragma-dialectical methodology, a party in an argumentative discussion can be assumed to manoeuvre strategically between dialectical and rhetorical objectives. One confrontational form of strategic manoeuvring occurs when a critic charges an arguer with advancing a standpoint that has socially harmful consequences. In special situations this form of manoeuvring can be dialectically sound, for example when the standpoint is advanced in a way that damages the dialectical process. The boundary between fallacious and dialectically sound applications of this form of manoeuvring is examined by looking for the manoeuvring’s soundness conditions.

领导幽默(leader humor), 作为一种有效的管理工具和手段, 近年来受到了理论界和实务界的广泛关注。在回顾领导幽默概念的基础上, 深入探究了领导幽默的影响效果及其作用机制, 总结发现领导幽默相关研究主要围绕七种视角展开, 分别是关系过程视角、社会交换理论、社会信息加工理论、关系认同视角、积极情绪视角、压力释放视角以及领导风格类型视角。未来研究应基于互动和结构的视角探讨领导幽默的影响效果以及基于社会信息加工理论关注领导幽默的作用机制。     

Finding Missing Proofs with Automated Reasoning

This article features long-sought proofs with intriguing properties (such as the absence of double negation and the avoidance of lemmas that appeared to be indispensable), and it features the automated methods for finding them. The theorems of concern are taken from various areas of logic that include two-valued sentential (or propositional) calculus and infinite-valued sentential calculus. Many of the proofs (in effect) answer questions that had remained open for decades, questions focusing on axiomatic proofs. The approaches we take are of added interest in that all rely heavily on the use of a single program that offers logical reasoning, William McCune's automated reasoning program OTTER. The nature of the successes and approaches suggests that this program offers researchers a valuable automated assistant. This article has three main components. First, in view of the interdisciplinary nature of the audience, we discuss the means for using the program in question (OTTER), which flags, parameters, and lists have which effects, and how the proofs it finds are easily read. Second, because of the variety of proofs that we have found and their significance, we discuss them in a manner that permits comparison with the literature. Among those proofs, we offer a proof shorter than that given by Meredith and Prior in their treatment of ukasiewicz's shortest single axiom for the implicational fragment of two-valued sentential calculus, and we offer a proof for the ukasiewicz 23-letter single axiom for the full calculus. Third, with the intent of producing a fruitful dialogue, we pose questions concerning the properties of proofs and, even more pressing, invite questions similar to those this article answers.     

I’m curious,I’m open to it,I test it,I trust it! A focus groups study to understand a-priori trust in automated buses

Trust is regarded as one of the main predictors for adopting automated buses (ABs). However, theories about trust (development) in technology generally vary and an in-depths study about trust in ABs specifically is still outstanding. The present study fills this gap by presenting results from focus group interviews to trust (development) in shared automated buses prior to exposure. The objectives of this study are to contrast participants’ naïve concepts of trust with theory and to identify underlying factors influencing a-priori trust in ABs. Results show that the N = 21 focus group participants use different strategies to familiarise themselves with the new technology of ABs, e.g., comparisons with familiar technologies, fundamental tendencies to approach or avoid, additional information seeking, or anthropomorphisation. These strategies largely support existing theories on trust (development) in technology. Differences between naïve interpretations of trust and its theoretical assumptions were found in focus group debates where more control over technology limited uncertainty and led to more trust. While theories suggest control and trust to be incompatible opposites, participants see control as a way to enhance trust. We provide starting points for further theory development and expansion and stress the importance of explanations in emerging technologies for trust and acceptance building.     

Procrastination,consideration of future consequences,and episodic future thinking

Despite the intrinsic temporal nature of procrastination, little research has examined the link between this form of self-regulatory failure and the consideration of future consequences, and no study has addressed the link between procrastination and episodic future thinking. The aim of the present study was to explore these relationships. Participants were asked to project themselves into possible future events and to rate the amount of sensory-perceptual details and autonoetic consciousness associated with their representations. They were also asked to complete questionnaires that assessed procrastination, the consideration of future consequences, and negative affect. Results showed that both the consideration of future consequences and episodic future thinking were associated with procrastination, and in particular with procrastination-related decision making abilities and procrastination-related motivational dispositions, respectively.
