Relationships between perceived life satisfaction, poor mental health, suicide ideation and suicide behaviors were examined in a statewide sample of 13 to 18 year old public high school students (n = 4,758) using the self-report CDC Youth Risk Behavior Survey (YRBS). Adjusted logistic regression analyses and multivariate models constructed separately (via SUDAAN), revealed that poor mental health (past 30 days), poor mental/physical health (past 30 days) serious suicide consideration (past 12 months), planning for suicide (past 12 months), attempted suicide (past 12 months) and suicide attempt requiring medical care (past 12 months) were significantly related to reduced life satisfaction. Also, differences across gender and race were demonstrated. Measures of life satisfaction as a component of comprehensive assessments of adolescent mental health, suicide ideation and suicide behavior in fieldwork, research, and program-evaluation efforts should be considered. 相似文献

‘Did you see that,Mom?’: Social Looking in Three‐Year‐Old Boys 总被引:1,自引:0,他引:1
This study examined social looking, defined as child‐initiated looking to a caregiver's face, in a sample of three‐year‐old boys and their mothers: 59.6% of boys looked to their mothers at least once over the course of emotion‐eliciting puppet show vignettes. Social looking occurred more often during puppet show events that were child‐focused and positive in valence. Boys’ social looking was related to their concurrent affective state, with more expressions of positive emotion looking associated with more social looks. Patterns of family emotionality predicted children's use of social looking. Specifically, a history of positive family expressiveness was associated with children's less frequent use of social looking, whereas a history of negative family expressiveness was associated with children's more frequent use of social looking. 相似文献

Abstract This case study is centered in northeast Washington State and northern Idaho and focuses on the social ecology of the wild edible huckleberry. The theoretical notion of social embeddedness is the lens through which the harvest and use of this much‐prized resource is viewed and analyzed. Using grounded theory as an over‐arching method, qualitative data were collected over two harvesting seasons regarding who harvests huckleberries in the study area and why. Four categories of use/users were identified. The results suggest a rich tapestry of social relations surrounding this resource that belies the simplistic notion of “commercial” vs. “recreational” use. These relations include temporal, geographic, economic, and cultural dimensions. Policy implications include the need to move beyond the commercial/recreational dichotomy in regulating the harvest of berries as well as the need to link the notions of community forestry and subsistence to the harvest of non‐timber forest products more generally. 相似文献

This paper is concerned with bringing together and drawing out some diverse strands of thought and action that are striving—from within a broadly green anti-capitalist agenda—to produce a rural space that is different from and a challenge to the mainstream trajectories that the production of the rural is taking in the global North. First, I outline the main elements of a new model for thinking about rural space in general that tries to incorporate three different facets of ‘space’ that have been teased out through geographical scholarship. This draws inspiration from work by Henri Lefebvre. After demonstrating this model in respect of the post-1945 productivist rural, I introduce it to debates about the emerging contours of the post-productivist countryside. Drawing predominantly on British examples, the second half of the paper develops one element within the heterogeneous potentiality of this post-productivism to consider some key aspects of what I term an example of ‘radical’ rural spatiality. This examines its perceived localities, conceived formal representations and partially lived everyday lives. The final main section gives brief consideration to opportunities now being presented to this radical rurality but also notes the considerable challenges that lie ahead. 相似文献

In a linear regression model, the Dantzig selector (Candès and Tao, 2007) minimizes the L1 norm of the regression coefficients subject to a bound λ on the L∞ norm of the covariances between the predictors and the residuals; the resulting estimator is the solution of a linear program, which may be nonunique or unstable. We propose a regularized alternative to the Dantzig selector. These estimators (which depend on λ and an additional tuning parameter r) minimize objective functions that are the sum of the L1 norm of the regression coefficients plus r times the logarithmic potential function of the Dantzig selector constraints, and can be viewed as penalized analytic centers of the latter constraints. The tuning parameter r controls the smoothness of the estimators as functions of λ and, when λ is sufficiently large, the estimators depend approximately on r and λ via r/λ2. 相似文献

Five elements are cited as being critical for a university-based retirement communities’ (UBRCs’) success: proximity to the university, two-directional programming, continuing care, a financial link to the university, and a minimum 10% resident connection to the university. We illustrate these criteria using examples from existing UBRCs. The comparisons are then contextualized in the broader framework of Social-Physical Place Over Time (SPOT) theory. SPOT theory focuses on the interactions between social and physical places among older adults. By analyzing the intersections between SPOT theory and UBRC criteria, we identify additional criteria to improve the definition of a UBRC: transportation support and facilitating activity. UBRCs offer value because they provide the social and physical place where older adults can live when they retire, thereby improving changes in individual agency and belongingness needs, which are key tenets of SPOT theory. The integration of the UBRC criteria and the SPOT theory framework builds on this relatively new meta-theory in environmental gerontology. SPOT theory effectively highlights how UBRCs benefit older adults and the community; UBRCs provide significant benefits not only to older adult residents, but also to the university communities that house them. 相似文献

Emotion Socialization by Mothers and Fathers: Coherence among Behaviors and Associations with Parent Attitudes and Children's Social Competence 总被引:1,自引:0,他引:1
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
