Asymptotic posterior normality for multiparameter problems

For asymptotic posterior normality in the one-parameter cases, Weng [2003. On Stein's identity for posterior normality. Statist. Sinica 13, 495–506] proposed to use a version of Stein's Identity to write the posterior expectations for functions of a normalized quantity in a form that is more transparent and can be easily analyzed. In the present paper we extend this approach to the multi-parameter cases and compare our conditions with earlier work. Three examples are used to illustrate the application of this method.     

Managing Multiple Facets of Risk in New Product Alliances*

The trend of forming alliances to develop new products continues; however, many of these new product alliances fail. As such we explore how key risk types intrinsic in new product alliances, performance, relational, and knowledge appropriation risks, influence alliance success. Further, we theorize that different alliance governance mechanisms can reduce the negative impact of risks on alliance success. To disentangle possible heterogeneous factors across firms that may affect the interplay of risk assessments and the use of governance mechanisms, we employ latent class regression analysis on survey data collected from 128 new product alliance firms and find support for a two‐regime solution. Longer alliance relationships and lower technological turbulence are factors for some firms (regime one), while the opposite are factors for other firms (regime two). These two regimes show different patterns in the interplay of risk assessments and governance for alliance success. Our theory and results support viewing risk as a multiple‐factor concept and by understanding the different impacts of the risk types in new product alliances and how governance mechanisms mitigate such effects, we aid managers' decision making regarding the balance of contractual versus normative governance in new product alliances. Understanding the heterogeneous factors inherent in these complex relationships enables managers to understand the conditions in which various governance mechanisms promote new product alliance success.     

The unique relationship between childhood sexual abuse,self-injury and suicide ideation: The mediating role of emotion dysregulation

Child sexual abuse (CSA) has serious short-term and long-term effects, including non-suicidal self-injury (NSSI) and suicidal ideation (SI). One possible thread linking CSA to NSSI and suicide risk is emotion dysregulation. The current study assessed whether facets of emotion dysregulation mediated relations of NSSI behaviours and functions, and SI. Participants (N = 121; Mean age = 18.69, age-range 18–22; 78 per cent female), college students with a history of childhood trauma, completed an online survey. Results indicated that facets of emotion dysregulation (i.e. clarity, non-acceptance) mediated the relationship between CSA and SI. CSA was associated with automatic negative reinforcement, social negative and social positive reinforcement NSSI functions, but was not associated with NSSI behaviours. Emotion dysregulation facets did not mediate the relationship between CSA and NSSI functions. Findings highlight the need to help CSA survivors have clarity and acceptance of emotional experiences to reduce SI risk. This research did not receive any specific grant from funding agencies in the public, commercial or not-for-profit sectors.     

Fictions and Facts about Parents and Parenting Older First-Time Entrants to Foster Care

Knowledge about the parents of older first-time entrants into foster care is embedded in fictions created by media images, anecdotal stories of professionals in the child welfare system, as well as reports and observations of youths who have experienced foster care. Even though there are caring and effective nonrelatives who are foster parents, the public perception of non-relative foster parents is sometimes quite negative. In order to separate some of the facts from some of the fictions about the parents/caregivers of older first-time entrants to foster care, this article will describe the parents and relative caregivers (grandparents and others) of older first-time entrants to foster care in an urban public welfare agency by examining maltreatment data.     

Perceptions of Misogyny in Hip Hop and Rap: What Do the Youths Think?

This article presents the results of an exploratory study conducted at a community forum sponsored by a prominent African American church and a historically Black university. These institutions are concerned with negative messages given to African American females about their appearance and their morals. The data presented describe the population of female (68.6%) and male (31.4%) participants ages 18 to 24 and inform us about their perceptions about hip hop and rap music, especially as they relate to misogyny. This study found that listening habits and age were significant in understanding youths' views about misogyny.     

Making welfare subordinate to market activities: Reconstructing social security in Hong Kong and Mainland China

Both the Mainland Chinese and Hong Kong Special Administrative Region governments have recently been reforming their social security policies with the emphasis on welfare residualism. This paper is intended to discuss the background to the reforms and to demonstrate how the reforms are designed to reduce the governments' commitment to meeting social needs. It argues that the two governments, by developing the entry, exit, double entry, and double exit systems of social security services, have attempted to strengthen the role of the private market in regulating people's entrance to both the labour and consumption market, and public welfare services.
