AUGUSTINE AND THE LIMITS OF PREEMPTIVE AND PREVENTIVE WAR

While Michael Walzer's distinction between preemptive and preventive wars offers important categories for current reflection upon the Bush Doctrine and the invasion of Iraq, it is often treated as a modern distinction without antecedent in the classical Christian just war tradition. This paper argues to the contrary that within Augustine's corpus there are passages in which he speaks about the use of violence in situations that we would classify today as preemptive and preventive military action. While I do not claim that Augustine makes an explicit distinction between the two types of war (such would be anachronistic), I will argue that based on examinations of De libero arbitrio I.v.11–12 and De civitate Dei I.30 Augustine's discussions of hypothetical cases or actual wars in history provide insights helpful for contemporary reflection on preemptive and preventive wars.     

Self-guided behavioral skills training: A public health approach to promoting nurturing care environments

The World Health Organization identified the promotion of “Nurturing Care Environments” as a global health priority. Responsive caregiving, 1 of 5 domains describing nurturing care, is critical for healthy child development. Relatively little research has evaluated population-level interventions aimed to increase responsive caregiving during the first 1,000 days of an infant's life. In this pilot study, we evaluated an intervention designed for population-level dissemination that targeted responsive caregiving. The self-guided behavioral skills training aimed to teach mothers to imitate infant vocalizations. The intervention was delivered within an on-line asynchronous training. All 3 mothers increased vocal imitative behavior following training without receiving coaching or behavior-specific feedback from an implementer. The results offer a preliminary proof of concept with implications for population-level intervention design and evaluation.     

Impressions of World of Warcraft players’ personalities based on their usernames: Interobserver consensus but no accuracy

Millions of people interact in the context of massively-multi-player-online-role-play-games (MMORPGs). Here we address whether MMORPG usernames convey accurate information about users’ personalities. Impressions based on email addresses show some accuracy but MMORPG’s are different because they provide little accountability, with little expectation that users will ever meet in person. We assessed consensus and accuracy in impressions based on 1357 (153 females) World of Warcraft users. Ratings of the usernames in terms of the Big Five dimensions yielded strong consensus (mean ICC = .46) but low accuracy (mean r = .01). Lens-model analysis suggest that features of the usernames have little validity, but observers used them anyway. Discussion focuses on why results might differ from those based on email addresses.     

Using HLM to Explore the Effects of Perceptions of Learning Environments and Assessments on Students’ Test Performance

The study examines the role that perceptions or impressions of learning environments and assessments play in students’ performance on a large-scale standardized test. Hierarchical linear modeling (HLM) was used to test aspects of the Learning Errors and Formative Feedback model to determine how much variation in students’ performance was explained by students’ and school principals’ perceptions of learning environments and assessments. Results from sequential HLM testing indicated that students’ but not principals’ perceptions explained a significant, although modest, amount of the total variation in students’ test performance. These results suggest that when students perceive learning environments to be safe and valuable, and positive assessment activities to be taking place, they tend to perform better on standardized tests than when they perceive learning environments and assessment activities otherwise. These findings provide a rationale for investigating the variables that can help improve students’ perceptions in order to enhance their test performance.     

Can home heal worn out parents?

The purpose of this study was to explore the conditions that make residences function as restorative environments for parents with young children. We analyzed how perceived restorativeness factors (being away, fascination, coherence, scope, and compatibility), the evaluation of the residence, interpersonal support, and the number of children contribute to actual psychological restoration in the residence using stepwise multiple regression. The results showed that perceived restorativeness factors needed for actual psychological restoration in residences depend on the working status and parental role. For nonworking mothers, fascination and interpersonal support significantly contributed to the prediction of their actual psychological restoration in the residence. For working mothers, only being away contributed significantly to predicting actual psychological restoration in the residence. For fathers, only compatibility contributed significantly to predicting actual psychological restoration in the residence. A need for future studies to examine whether the differences were caused by the fact that one is engaged in paid work or by the fact that potential stressors are distributed both inside and outside the residence was discussed.     

Visions and Aspirations

SUMMARY

This chapter explores key characteristics of an ideal feminist educational environment, one that specifically focuses on the intellectual development and training of feminist therapists. Such an environment is dependent on an ongoing relationship among three entitiesstudents, instructors, and the institutionand characteristics of each of these three entities are discussed. The chapter evaluates the present climate within universities, and whether that climate offers the potential to promote or stifle a feminist environment.     

Classroom context,teacher expectations,and cognitive level: Predicting children's math ability judgments

Classroom practices that make ability differences salient communicate differential teacher expectations for students. This study reports on a new observational tool for measuring Classroom Ability-based Practices (CAP) and explores how young children's self-perceptions of ability in mathematics are related to their teachers' expectations for them and to their cognitive reasoning skills in classrooms that vary in usage of such ability-differentiated practices. The sample consisted of 193 children and their teachers in 15 first grade classrooms. The CAP was a reliable measure of ability-based differential teacher treatment and showed criterion validity as a moderator variable in predicting children's ability perceptions. In highly ability-differentiating classrooms, children's self-ratings were more congruent with teachers' expectations of students' mathematics ability. Also in highly ability-differentiating classrooms, higher cognitive levels predicted lower self-ability ratings in math. These findings extend our understanding of the social and cognitive factors that shape young children's self-judgments of math competence.

Mainstreams and Perspectives in Research on Learning (Mathematics) From Instruction

Le domaine de l’enseignement et de l’apprentissage des mathématiques est un exemple des plus représentatives de l’orientation des recherches sur l’apprentissage et l’instruction dans les différentes matières. Au cours du dernier quart de siècle écoulé, ce champ de questionnement a produit nombre d’investigations qui résultent d’une conception de l’apprentissage des mathématiques comme construction sociale de la signification et de la comprehension basée sur la modélisation de la réalité. Dans cet article, quelques tendances majeures et perspectives de recherche s.0s principalement aux Etats‐Unis et en Europe. Il y sera montré que d’une part, les investigations empiriques ont déjà produit des blocs de construction pour l’élaboration d’une théorie de l’apprentissage des mathématiques à partir d’instructions mais que, d’autre part, des questions et des problèmes majeurs requièrent d’être démêlés par la poursuite d’investigations. Ceci y sera documenté de façon exemplaire en utilisant comme cadre de référence quatre composants principaux d’une théorie de l’apprentissage des mathématiques à partir d’instructions: une théorie de l’expertise visant à analyser des compétences dans un domaine; une théorie de l’acquisition tendant à comprendre et expliquer les processus d’apprentissage qui conduisent à la réalisation de compétences; une théorie de l’intervention, focalisée sur la conception d’environnements enseignement‐apprentissage puissants pour provoquer ces processus d’acquisition; et une théorie de l’évaluation s’adressant au développement de méthodes et techniques pour la construction et l’application d’outils et instruments d’évaluation. The domain of mathematics learning and teaching is one of the most representative examples of the subject‐matter orientation in research on learning and instruction. During the last quarter of the past century this field of inquiry has produced a vast body of investigations, resulting in an enriched conception of mathematics learning as involving the (social) construction of meaning and understanding based on modeling of reality. In this article some of the main trends and perspectives in the field of research on mathematics learning and instruction are discussed, and illustrated with examples of empirical research, mainly carried out in Europe and the United States. It will be shown that, on the one hand, the available empirical investigations have already yielded substantial building blocks for the elaboration of a theory of mathematics learning from instruction, but that, on the other hand, major issues and problems need to be unravelled by continued inquiry. This will be documented in an exemplary way, using as a frame of reference four main components of a theory of learning mathematics from instruction: a theory of expertise, aiming at analysing competence in a domain; a theory of acquisition, attempting to understand and explain the processes of learning that are conducive to the attainment of competence; a theory of intervention, focusing on the design of powerful teaching–learning environments for eliciting those acquisition processes; and a theory of assessment, addressing the development of methods and techniques for the construction and application of assessment tools and instruments.     

A particular resiliency to threatening environments

Being in the numerical minority can impair intellectual performance. We suggest, however, that these negative effects need not extend to everyone because some people—specifically high self-monitors—can overcome the effects of situationally activated stereotypes. In two studies, we manipulated the race/sex composition of small groups and assessed intellectual performance. Results revealed that: (a) self-monitoring moderated the effects of group-composition on performance, such that it was positively related to performance in stressful minority settings, (b) the number of out-group members in a group caused a linear effect on performance that differed for high and low self-monitors, and (c) stereotype activation mediated self-monitoring’s moderating effect on performance. Thus, high self-monitors may be resilient to threatening environments because they react to negative stereotypes with increased (and not decreased) performance. We discuss these results in relation to theories of inter-group contact, stereotype threat, and stress and coping.
