How positively adolescents believe others feel about their ethnic‐racial group (i.e., public regard) is an important part of their ethnic‐racial identity (ERI), which is likely informed by contextual and individual factors. Using cluster analyses to generate ERI statuses among Black, Latino, and White adolescents (n = 1,378), we found that associations between peer versus adult discrimination and public regard varied across ERI status and ethnic‐racial group. However, among all adolescents, an achieved ERI (i.e., having explored ethnicity‐race and having a clear sense about its personal meaning) buffered the negative association between adult discrimination and public regard, but not between peer discrimination and public regard. Implications for understanding the interplay between contextual and individual factors for public regard are discussed. 相似文献

In the United States, 5.3 million children and adolescents are growing up either with unauthorized status or with at least one parent who has that status. Until recently, little in the way of research has informed federal, state, and local policy debates related to unauthorized status (e.g., border enforcement, deportation, and a pathway to citizenship) although these issues have important implications for youth development. This statement is a brief summary of the research evidence on multiple domains of development that may be affected by the child or parent's unauthorized status. We also describe the contextual and psychological mechanisms that may link this status to developmental outcomes. We summarize a range of policies and practices that could reduce the developmental harm to children, youth, and their families stemming from this status. Finally, we conclude with recommendations for policy, practice, and research that are based on the evidence reviewed. 相似文献

As Canadian postsecondary systems have expanded they have become more institutionally differentiated. In British Columbia, distinctions are made between research‐intensive universities (RIUs) and teaching‐intensive universities with respect to resources, programming, and perceived prestige value. We employ an effectively maintained inequality framework to examine the role played by ethnicity in the competition for admission to RIUs. Our findings indicate that, together with socioeconomic status and gender, ethnicity is significantly related to RIU attendance rates. Ethnic group differences were particularly marked—Chinese and Korean speakers being most likely and Tagalog speakers least likely to attend an RIU. High school grade point averages and English language proficiency scores moderated only some of these differences, raising questions about the efficacy of competitive admissions policies based solely on academic merit. 相似文献

For social analysts, what has come to be called the “sharing economy” raises important questions. After a discussion of history and definitions, we focus on 3 areas of research in the for‐profit segment, also called the platform economy: social connection, conditions for laborers, and inequalities. Although we find that some parts of the platform economy, particularly Airbnb, do foster social connection, there are also ways in which even shared hospitality is becoming more like conventional exchange. With respect to labor conditions, we find they vary across platforms and the degree to which workers are dependent on the platform to meet their basic needs. On inequality, there is mounting evidence that platforms are facilitating person‐to‐person discrimination by race. In addition, platforms are advantaging those who already have human capital or physical assets, in contrast to claims that they provide widespread opportunity or even advantage less privileged individuals. 相似文献

Autocovariance Estimation in Regression with a Discontinuous Signal and m‐Dependent Errors: A Difference‐Based Approach
下载免费PDF全文

We discuss a class of difference‐based estimators for the autocovariance in nonparametric regression when the signal is discontinuous and the errors form a stationary m‐dependent process. These estimators circumvent the particularly challenging task of pre‐estimating such an unknown regression function. We provide finite‐sample expressions of their mean squared errors for piecewise constant signals and Gaussian errors. Based on this, we derive biased‐optimized estimates that do not depend on the unknown autocovariance structure. Notably, for positively correlated errors, that part of the variance of our estimators that depend on the signal is minimal as well. Further, we provide sufficient conditions for ‐consistency; this result is extended to piecewise Hölder regression with non‐Gaussian errors. We combine our biased‐optimized autocovariance estimates with a projection‐based approach and derive covariance matrix estimates, a method that is of independent interest. An R package, several simulations and an application to biophysical measurements complement this paper. 相似文献

Sharing personal information in the child protection context: Impediments in the Australian legal framework
下载免费PDF全文
![点击此处可从《Child & Family Social Work》网站下载免费的PDF全文](/ch/ext_images/free.gif)
Professionals, including social workers, in the child protection context are frequently required to make decisions on whether to share sensitive personal information about children, their families, and others with colleagues and across institutional and jurisdictional boundaries. Sharing information across agencies and organisations is essential to allow joined‐up service provision and to effectively protect and support children and their families. A legal framework that supports this decision making is a necessary, although not sufficient, condition for effective information sharing. This article examines the complex legal framework that governs information sharing across the Australian states and territories. It identifies a number of structural and regulatory elements that unnecessarily limit information sharing or have a tendency to create a culture that is risk averse, rather than proactive, in sharing information. The article suggests structural and regulatory reforms that would improve the legal framework for sharing information, while at the same time giving due recognition to the human rights that come into tension in this policy context: the right to privacy and the rights of the child. 相似文献

Childhood adversity,adult homelessness and the intergenerational transmission of risk: a population‐representative study of individuals in households with children

This study tested for associations between childhood adversity, adult homelessness and contexts of developmental risk in households with children. Data were drawn from the 2010 Washington State Behavioral Risk Factor Surveillance System, representative of the population of Washington State residents. Considering adults in households with children, those who experienced higher levels of childhood adversity were more likely to have experienced homelessness in adulthood. Meanwhile, a 10‐factor index of cumulative developmental risk was independently associated with childhood adversity and with adult homelessness. Adult homelessness appears to represent a circumstance through which past childhood adversities are brought forward and associated with contexts of developmental risk for subsequent generations of children. 相似文献

Exploring Infant Gesture and Joint Attention as Related Constructs and as Predictors of Later Language

In infancy, use of gesture and the ability to engage in joint attention with others both predict later language development. Conceptually, gesture and joint attention abilities may reflect a similar underlying social‐communicative skill. However, these abilities are often studied separately. Despite the fact that gesture is often used in episodes of joint attention, little is known about the degree to which measures of gesture use and joint attention ability are associated with one another or how they similarly, or differentially, predict children's language abilities. Participants in this study were 53 infants. At 12 months, multiple measures of infants’ gesture use were gleaned from a free–play interaction with a parent. Infants’ responding to and initiating joint attention were measured via the Early Social‐Communicative Scales (Mundy et al., 2003). Infants’ expressive and receptive language was measured at 24 months with the Mullen Scales of Early Learning (Mullen, 1995). A factor analysis including gesture and joint attention measures indicated that at 12 months, joint attention, particularly responding to joint attention, reflects a similar underlying construct with infant gesture use, yet they uniquely predict later language ability. 相似文献

The decline in Latin America's skill premium and income inequality during the 2000s was partly driven by an economic expansion that favored low‐skill‐intensive service sectors. Evidence shows inequality becomes countercyclical in the 2000s, and unlike previous expansions, the boom was concentrated on services while manufacturing lagged behind. I build an open economy general equilibrium model that features a low‐skill‐intensive nontradable sector. The model suggests that favorable shocks to commodity prices and international interest rate spreads, such as those that buffeted Latin America in the 2000s, account for about a fifth of the observed decline in the skill premium.

In this paper, we study quality‐of‐service (QoS) based pricing schemes that serve as incentive mechanisms to induce sharing behaviors in Peer‐to‐Peer (P2P) networks. We incorporate operational QoS metrics into users’ utility functions and demonstrate how they affect individual users’ content sharing decisions. Using a game‐theoretic model, our study reveals how organizations respond to the changes of operational QoS metrics in their design of pricing schemes for various business objectives at different stages of network evolution. Our results show that a higher upload capacity can foster rational sharing to start when the network is small; however, it also discourages sharing behaviors when the network becomes large. In order to induce a socially optimal behavior, a pricing scheme will not charge users for requesting content while compensating them for sharing content. Such compensation is found to increase faster with the network size when the network is large. In order to maximize the profit of a monopolistic provider, however, a pricing scheme will charge content requests with a positive price while providing less compensation to sharing users compared to the socially optimal scheme. When the network size is small, such compensation can be even negative, which implies that a monopolistic provider discourages content sharing when the network is small, but encourages it when the network becomes larger. In addition, we find that more information about peer upload capacity discourages peers to share. 相似文献
