This paper presents an analysis of the relationship between community characteristics, household attributes, and child survival in Brazil. The principal objectives are to investigate how the social and environmental context in which a child is raised affects his or her survival chances, and to analyze how household variables modify the effects of community characteristics. The interaction effects we examine help to explain the effects of community characteristics on child survival chances by illuminating the most likely pathways through which these covariates operate. This information is also useful for predicting who is most likely to benefit from public policies to improve community infrastructure. education, and health care. 相似文献

The attacks on the World Trade Center and the Pentagon on 11 September 2001 (9/11) radically destabilized the US sense of self and thus necessitated a particular reassertion of state identity that pivots violently on gender and race. This identity draws upon hypermasculinity, a religious code of ethics and the constitutive differences between Self/Other necessitating the persistent and forceful coding, interpretation and targeting of particular actors and politics as Islamic fundamentalist. In particular, 9/11's post-traumatic space requires US participation in an orientalist project that institutionalizes gendered and racialized violence through the infantilization, demonization, dehumanization and sexual commodification of the ‘Other’. The US state project to ‘save’ its identity intertwines religion, ideology and conflict so as to permanently etch within the American psyche a fear/loathing/paternalism regarding the ‘Orient’ abroad and within. This article proposes a feminist theoretical framework for empirically understanding and recognizing orientalism's logic in US state identity making. 相似文献

Let X =(x)ij=(111, …, X,)T, i = l, …n, be an n X random matrix having multivariate symmetrical distributions with parameters μ, Σ. The p-variate normal with mean μ and covariance matrix is a member of this family. Let be the squared multiple correlation coefficient between the first and the succeeding p1 components, and let p2 = + be the squared multiple correlation coefficient between the first and the remaining p1 + p2 =p – 1 components of the p-variate normal vector. We shall consider here three testing problems for multivariate symmetrical distributions. They are (A) to test p2 =0 against; (B) to test against =0, 0; (C) to test against p2 =0, We have shown here that for problem (A) the uniformly most powerful invariant (UMPI) and locally minimax test for the multivariate normal is UMPI and is locally minimax as p2 0 for multivariate symmetrical distributions. For problem (B) the UMPI and locally minimax test is UMPI and locally minimax as for multivariate symmetrical distributions. For problem (C) the locally best invariant (LBI) and locally minimax test for the multivariate normal is also LBI and is locally minimax as for multivariate symmetrical distributions. 相似文献

Reflected self-appraisal suggests that individual functioning is related to the fit between individual characteristics and the norms of their primary contexts. To apply this social psychological concept to the study of obesity, we hypothesized that adolescents at risk of obesity would have lower academic achievement overall than other students, especially in schools in which their weight status was most likely to elicit negative evaluations. Multi-level modeling of nationally representative data revealed that the negative longitudinal association between risk of obesity and achievement was stronger in schools with higher rates of romantic activity and lower average body size among students, two school contexts in which obesity was likely to be stigmatized, but weaker in schools with higher rates of athletic participation, a school context in which such stigmatization was also likely. Additional analyses suggested that this last, unexpected finding reflected a process of niche-picking. 相似文献

This paper is concerned with a partially explosive linear model with polynomial regression components generating a pair of
related time series. The least squares estimates of the coefficients are shown to be √N-consistent and asymptotically singular
normal, when the degrees of polynomial regression components are same, thus generalising a result due to Venkataraman (1974). 相似文献

In this paper, estimation of coefficients of simultaneous linear partially explosive model of higher orders with moving average
errors is considered. It has been shown that the above model can be decomposed into a purely explosive model and an autoregressive
model. A two stage estimation, procedure is carried out towards proposing estimators for the partially explosive model. The
asymptotic properties of these estimators are also studied. 相似文献

Despite the burgeoning research on social enterprise (SE), there is a dearth of research that investigates the biographical factors that influence the emergence of SEs in the form of hybrid organizations on a large scale. Drawing on the emerging narrative perspective of SE, we examine the biographical narratives of 317 self-identified social entrepreneurs who were selected as fellows by two of the world’s largest SE support organizations: Ashoka and the Schwab Foundation. We employ Gioia’s methodology and principal component analysis to derive and subsequently classify the biographical antecedents of SE emergence. This study makes a novel contribution to the SE-as-hybrid-organization literature by revealing eight biographical antecedents of SE emergence, four of which can be categorized into social skills, and four others can be categorized into economic skills, which constitute SE’s social position. We also develop a typology of SE based on different combinations of individuals’ social skills and social position. Finally, we discuss the implications of this study for the SE-as-hybrid-organization literature, highlight its limitations, and present possible avenues for future research. 相似文献

Screen/report design for output organization is still very much a common sense-driven activity. This paper identifies a preliminary set of factors beyond display format for examination as screen/report design variables. A laboratory experiment was conducted to assess the influence of one of these factors, spatial layout of information, along with display format in an information recall context. Individual imagery orientation (verbalizer/visualizer) was used as a moderating variable in the experimental design. The findings indicate that spatial layout of information significantly influenced performance when the recall task involved pattern detection. In fact, a central location of data in a document was the most conducive to pattern recall performance. Further, terminal items facilitated pattern recall better than early input items. With respect to display format, the results support previous findings that a tabular display enhances performance for point-value recall tasks while graphs exhibit an edge over tables for pattern types of recall tasks. Overall, the verbalizers demonstrated a complete supremacy in performance. Interaction between individual imagery orientation and display format indicates that, while the verbalizers and the mixed type were immune to display format variations, the graphical stimulus enhanced the pattern recall performance of the visualizers. 相似文献

Several studies have examined the influence of organizational context (e.g., organization size, environment, strategy) on information systems (IS) performance/success. But very few studies have examined IS structure, and those studies have focused on a particular element of IS structure (e.g., decentralization). Thus, the multidimensional structural configuration of IS as an organizational subunit has escaped research attention. Further, the nature of the task to be performed by the IS subunit as a contextual factor has been virtually ignored in the IS research literature. In this paper, we first develop a congruence model for the task-structure relationship in an information systems development (ISD) subunit setting. Then we test this model as a multivariate relationship followed by subordinate bivariate analyses. Analysis of data from 41 hospitals’ ISD subunits reveals that a congruence relationship between task context and the structure of an ISD subunit is present. Our findings also show that an exclusive association exists between uncertainty in the task environment and the decision-making structure. Likewise, the association between equivocality of task content and the control structure of the ISD subunit is also exclusive. Implications of these findings for decision makers and researchers are discussed. 相似文献
