This study examined inter‐relations among different types of parental emotion socialization behaviors in 88 mothers and 76 fathers (co‐residing with participating mothers) of eight‐year‐old children. Parents completed questionnaires assessing emotion socialization behaviors, emotion‐related attitudes, and their children's social functioning. An observed parent–child emotion discourse task and a child social problem‐solving interview were also performed. Parent gender differences and concordance within couples in emotion socialization behaviors were identified for some but not all behaviors. Fathers' reactions to child emotion, family expressiveness, and fathers' emotion coaching during discussion cohered, and a model was supported in which the commonality among these behaviors was predicted by fathers' emotion‐coaching attitudes, and was associated with children's social competence. A cohesive structure for the emotion socialization construct was less clear for mothers, although attitudes predicted all three types of emotion socialization behavior (reactions, expressiveness, and coaching). Implications for developmental theory and for parent‐focused interventions are discussed.  相似文献

Social scientists from different fields have identified security as a future-oriented mode of governance designed to preserve the social order from diverse types of global risk through international cooperation, militarization and privatization of the state security apparatus, surveillance technologies, community policing, and stigmatization of identities and behaviors deemed dangerous. This literature has largely been limited to English-speaking countries in the Global North, however, that are relatively “secure.”. To understand how security operates in a different context, this article focuses on the current War on Crime in México using newspaper and magazine articles, government documents, and extant academic research. In México, it is argued, the basic elements of security governance (international cooperation, militarized police, surveillance technologies, law, etc.) are present, but in modified form. Rather than focusing on external risks that could develop into future threats, security in México is turned inward against traditional forms of national economic, political, and cultural life thought to produce harm in the present. This, in turn, underscores security’s unique purpose in the country, which is not to preserve the prevailing social order, but to transform an emergent social order that through globalization has come to threaten the state’s legitimacy. These observations suggest an international divide in the operation of security that leaves those most vulnerable in the Global South to bear the greatest costs.  相似文献

The domain of risk analysis is expanded to consider strategic interactions among multiple participants in the management of extreme risk in a system of systems. These risks are fraught with complexity, ambiguity, and uncertainty, which pose challenges in how participants perceive, understand, and manage risk of extreme events. In the case of extreme events affecting a system of systems, cause‐and‐effect relationships among initiating events and losses may be difficult to ascertain due to interactions of multiple systems and participants (complexity). Moreover, selection of threats, hazards, and consequences on which to focus may be unclear or contentious to participants within multiple interacting systems (ambiguity). Finally, all types of risk, by definition, involve potential losses due to uncertain events (uncertainty). Therefore, risk analysis of extreme events affecting a system of systems should address complex, ambiguous, and uncertain aspects of extreme risk. To accomplish this, a system of systems engineering methodology for risk analysis is proposed as a general approach to address extreme risk in a system of systems. Our contribution is an integrative and adaptive systems methodology to analyze risk such that strategic interactions among multiple participants are considered. A practical application of the system of systems engineering methodology is demonstrated in part by a case study of a maritime infrastructure system of systems interface, namely, the Straits of Malacca and Singapore.  相似文献

There is a long-standing debate in Scotland over the use of upland areas, as initiatives to restore the native Caledonian pine forest are vying with traditional moorland management for shooting.  相似文献

The appeal I am making is (roughly speaking) for aid specialists to do more to help those of us who are not aid specialists to arrive at judgments about the effects of the work of (voluntary) aid agencies that we have at least some reason to think accurate. I argue that the fact that it is so difficult for us to arrive at such judgments at present has certain negative consequences, and that this gives those who are in a position to make it easier for us to arrive at such judgments strong reasons to do so. And I argue that (certain) aid specialists are in such a position. Hence my appeal to them to do so.  相似文献

New analytic forms for distributions at the heart of internal pilot theory solve many problems inherent to current techniques for linear models with Gaussian errors. Internal pilot designs use a fraction of the data to re-estimate the error variance and modify the final sample size. Too small or too large a sample size caused by an incorrect planning variance can be avoided. However, the usual hypothesis test may need adjustment to control the Type I error rate. A bounding test achieves control of Type I error rate while providing most of the advantages of the unadjusted test. Unfortunately, the presence of both a doubly truncated and an untruncated chi-square random variable complicates the theory and computations. An expression for the density of the sum of the two chi-squares gives a simple form for the test statistic density. Examples illustrate that the new results make the bounding test practical by providing very stable, convergent, and much more accurate computations. Furthermore, the new computational methods are effectively never slower and usually much faster. All results apply to any univariate linear model with fixed predictors and Gaussian errors, with the t-test a special case.  相似文献

Approximate expressions for the mean and variance of the MLE of Box's 2-way ANOVA degrees of freedom factor are given for the case when the usual F test for column effects is appropriate even though there is correlation across columns. A simulation study is performed showing the approximations are good for a variety of numbers of rows and columns. The results confirm that the estimated degrees of freedom factor is badly biased when no factor at all should be used.  相似文献
