Some theory and practical uses of trimmed L-moments

Trimmed L-moments, defined by Elamir and Seheult [2003. Trimmed L-moments. Comput. Statist. Data Anal. 43, 299–314], summarize the shape of probability distributions or data samples in a way that remains viable for heavy-tailed distributions, even those for which the mean may not exist. We derive some further theoretical results concerning trimmed L-moments: a relation with the expansion of the quantile function as a weighted sum of Jacobi polynomials; the bounds that must be satisfied by trimmed L-moments; recurrences between trimmed L-moments with different degrees of trimming; and the asymptotic distributions of sample estimators of trimmed L-moments. We also give examples of how trimmed L-moments can be used, analogously to L-moments, in the analysis of heavy-tailed data. Examples include identification of distributions using a trimmed L-moment ratio diagram, shape parameter estimation for the generalized Pareto distribution, and fitting generalized Pareto distributions to a heavy-tailed data sample of computer network traffic.     

Social Work and Blood Vengeance: The Bedouin-Arab Case

Correspondence to Alean Al-Krenawi, Department of Social Work, Ben-Gurion University of the Negev, Israel Summary The practice of blood vengeance, the obligation to kill in retributionfor the death of a member of one's family or tribe, is illegalin most countries of the world; however, many traditional culturesstill demand this form of maintaining honour. This paper outlinesthe cultural and historical contexts of the practice of bloodvengeance among the Bedouin of the Negev of Israel. It considersthe consequences for the targeted family and details the copingstrategies adopted by the family, especially the children, underconditions of extreme social, emotional and economic deprivation.It discusses social work intervention, from initial contactto partial resolution; strategies of cultural sensitivity arealso outlined.     

Development and change of young adults' preventive health beliefs and behavior: influence from parents and peers

A longitudinal data set is employed to explore the sources of stability and change in young adults' health beliefs and behavior concerning drinking, diet, exercise, and wearing seat belts. There is substantial change in the performance of health behaviors during the first three years of college, and peers have a strong impact on the magnitude of that change. In total, however, parents are much more important than peers as sources of influence over these beliefs and behaviors. Of the various social influence processes considered, the direct modeling of behavior appears to be the most important avenue of influence for both parents and peers. These data, along with previous papers in our research program, suggest a pattern of gradually increasing parental influence on their children's health beliefs and behavior while the children are living at home, and the persistence of that influence at least through the college years.     

Public accountability in non-profit industrial development organisations

Non-profit industrial development organisations (NIDOs) represent a common but little studied community response to widespread deindustrialisation in the United States. These non-profits are organised as chartered not-for-profit corporations, public authorities or agencies of local government. Most receive at least some public funding to promote local industrial development. Thus, a key issue is how accountable NIDOs are to the public they have been created to serve. Data from national surveys of NIDO executive directors in 1984 and 1994, as well as a survey of six case study boards of directors, suggest that public accountability is an increasingly important concern among NIDOs. Public hearings, efforts to diversify the boards in terms of gender and race, and connections to community development corporations and other local organisations are among the ways NIDOs attempt to be accountable to the general public. Although few women or racial minorities serve on NIDO boards, those boards with representation of these groups tend to be more concerned with public accountability. Boards containing public officials tend to be less concerned, presumably because their presence makes the NIDOs more directly accountable as a result of the participation of elected public representatives.     

Developing the Sexual Child

The idea that a child should not have sexual interests and experiences is fast being supplanted by the knowledge that he does have them; that they are an expression of perfectly normal, healthy energies, and that while it is necessary to gain control over them, they should not be forcibly suppressed” ( Renz & Renz 1935 : 92).     

Internet presence and historically black colleges and universities: Protecting their images on the World Wide Web?

This study examines how historically black colleges and universities (HBCUs) use their home pages to present images of themselves. The home pages of 96 institutions were examined using content analysis. The findings suggest that HBCUs are not using their home pages to project a strong image. For example, less than 10% of these institutional home pages made mention of institutional rankings, and less than 20% made mention of students, athletics or faculty. The authors make suggestions for how HBCUs can better project institutional image with changes to home page content and design.     

This is not a race, this is a farce: Formula One and the Indianapolis Motor Speedway tire crisis

Formula One is the most technologically advanced and financially lucrative form of motorsport in the world with global audiences in the billions over the course of a season. A highly unusual and potentially deadly set of events took place during the Friday practice for the sixth annual United States Grand Prix at the Indianapolis Motor Speedway. Controversy and blame soon followed. Using Benoit's public relations and image restoration strategy framework, this paper examines the different strategies employed during the crisis by the Formula One teams, Michelin, the Federation Internationale De L’Automobile, Formula One Management, and the Indianapolis Motor Speedway. An examination of the crisis situation at the United States Grand Prix allows this study to expand Benoit's initial framework into sport as well as examining the implications for public relations and image repair strategies.
