Optimum spacings for the joint estimation and tests of hypothesis of location and scale parameters of the cauchy distribution

A simultaneous test for the location and scale parameters of the Cauchy distribution is considered based on selected order statistics.. It is shown that optimum spacings that maximise the Pitman ARE of the test coincide with that of the optimum spacings for the estimation problem.     

Making Meanings,Meaning Identity: Hmong Adolescent Perceptions and Use of Language and Style as Identity Symbols

Using qualitative interview data gathered from 28 Hmong adolescents, we examined the meaning ascribed to language and style and how language and style behaviors are used to distinguish identity. We found that the participants used language and style to define their own ethnic group membership and cultural identities. Moreover they inferred meaning from these identity behaviors to discern which peer groups are desirable (those who wear American style clothing and are bilingual) and which are of low social status (“fobby” style clothing and monolingual). The cultural identity symbols used by participants reveal heterogeneity among Hmong adolescent peer groups and evolving definitions of what it means to be Hmong in America.     

Collaborative Approaches to Family Systems Supervision: Differentiation of Self

Many systems approaches speak to the importance of respectful mutual curiosity in supervision rather than linear teacher–learner didacticism. This paper provides an overview of collaborative approaches to supervision in family therapy. It then focuses on Bowen family systems and encouraging differentiation in the relationship process between supervisor and supervisee as a useful approach towards equal collaboration. The authors use case examples to illustrate what impedes and fosters mutuality in the supervision process where both supervisor and supervisee learn from each other.     

Changes in Risk Perceptions Prospectively Predict Changes in Self‐Reported Speeding

Risk perception theories posit that changes in risk perception prompt subsequent changes in risk behavior. Prospective studies using observations made at three time‐points offer the capacity to test this hypothesis by observing sequential changes in both risk perceptions and behavior. A telephone survey was administered by random‐digit dialing to 255 adult Australian drivers at baseline (T1), 6 weeks (T2), and 14 weeks (T3). During weeks 2–5, a risk‐perception‐based anti‐speeding mass media campaign was conducted. The survey assessed risk perception, operationalized as the proportion of time that driving at 70 km/h (43 mph) was perceived to be dangerous, and self‐reported speeding behavior, defined as the frequency of respondents driving 5 km (3 mph) faster than the legal speed limit in built up areas. Higher T2 risk perception predicted lower T3 self‐reports of speeding after controlling T1 risk perception and T1 and T2 self‐reported speeding. This can be interpreted as changes in risk perceptions between T1 and T2 predicting changes in speeding between T2 and T3. Further analyses showed that increases in risk perception predicted lower subsequent self‐reported speeding changes, but decreases in risk perception were unrelated to those changes. Risk perception changes were unrelated to recall of exposure to the media campaign. These findings support a dynamic view of the relationship between risk perception and self‐reported behavior, and that risk perception theories can be applied to speeding.     

Manufacturing ghost fathers: the paradox of father presence and absence in child welfare

Fathers exist in the lives of women and children involved with child welfare authorities, and yet, they are rarely seen by child welfare. This invisibility exists whether or not fathers are deemed as risks or as assets to their families. Using an analysis of fundamental child welfare policies and practices and relevant literature, the paper examines how 'ghost' fathers are manufactured, and how this phenomenon affects families and professionals in child welfare. An analysis of gender, class, race and culture of child welfare discourses shows how these fathers are seen as deviant, dangerous, irresponsible and irrelevant, and even further, how absence in child welfare is inextricably linked to blaming mothers. In failing to work with fathers, child welfare ignores potential risks and assets for both mothers and children.     

Being there: a family centre worker's role as a secure base for adolescent girls in crisis

Childcare social work practice with troubled adolescent girls can benefit from drawing on attachment theory, not only as a frame-work for understanding their relationship history and current behaviour but also as a framework for defining the nature and potential value of a specific kind of relationship provided by the social worker. This paper offers an analysis of the relevance of attachment theory for work with adolescent girls, particularly models of secure and insecure attachments, and examines practice experience in a family centre setting. The young women referred to the family centre had experienced a range of adversities, including sexual, physical and emotional abuse, which had seriously affected their development. They were drifting outside the systems of family, education and local authority care, because none of these could hold onto them. The paper describes how the social worker aimed to change their internal working model by offering them a different kind of relationship experience. She provided a secure base from which they could begin to develop trust, to repair their self-esteem and to build a sense of self-efficacy – the necessary ingredients for resilience and for more successful future relationships.     

Board development practices and competent board members: Implications for performance

This study explores underlying assumptions about board development practices in nonprofit governance. Specifically, a model was developed to determine if using recommended recruitment, board member orientation, and evaluation practices resulted in more competent board members and if the presence of these board members led to better board performance. The sample consisted of 1,051 survey responses from CEOs and board chairs representing 713 credit unions. As member‐benefit nonprofit organizations, credit unions rely almost exclusively on voluntary board members in an oversight capacity. Results support the contention that board development practices lead to more capable board members, and the presence of these board members tends to explain board performance. The study advances the understanding of nonprofit board development practices by further defining the concept and proposing an empirically tested assessment strategy. Furthermore, the findings support using specific recruitment practices that should strengthen nonprofit boards.
