Failure Rate Transform of the Weibull Variate and its Properties

The failure rate of a life time distribution has so for been studied in the time domsin. The present paper extends the failure rate transform in the frequency domain. For this purpose, the parent life time distribution has been taken as the Weibull distribution and different properties of the distribution of the failure rate transform have been presented including some characterisations of the Weibull distribution. Some comparative studies have also been made between the parent distribution and the failure rate transform distribution in respect of convex, star shaped and super additive orderings and expectation.     

Adaptive Cluster Sampling in Two‐stage Sampling

Adaptive cluster sampling can be a useful design for surveying rare and clustered populations. Here we present a new development in adaptive cluster sampling where we use a two‐stage design and extend the complete allocation sampling method. In the proposed new design the primary sample units are selected and, depending on the value of a preset condition, the entire primary unit is surveyed, as in complete allocation sampling. In the next step, if a second condition is met, the surrounding primary sample units are selected. We review the efficiency of the proposed design for sampling the New Zealand Castle Hill buttercups and provide unbiased estimators for the population total and sampling variance.     

A Tale of Two American Cities: Disaster,Class and Citizenship in San Francisco 1906 and New Orleans 2005

Destruction, notes David Harvey, “is often required to make the new urban geography out of the wreckage of the old.”² The history of San Francisco's Chinatown following the 1906 earthquake and fire and New Orleans' public housing following Hurricane Katrina in 2005 reveal how powerful class interests collude with the fog of disaster to lay claim to the urban spaces of the poor and marginal. In two historic U.S. disasters we witness the concerted efforts of urban elites to confiscate the spaces of two politically vulnerable populations: the Chinese in 1906 and low‐income African‐Americans in 2005. The widely varying outcomes of these two attempts reveal a good deal about the intersection of calamity, class, race, and citizenship in American history.     

Modern Multi-line Slot Machine Games: The Effect of Lines Wagered on Winners,Losers, Bonuses,and Losses Disguised as Wins

We simulated the commercially available multi-line slot machine game “Money Storm,” including its bonus wins. Our results show that after a specified amount of time (such as 1 or 50 h), when players played a single line, there were marked differences between one player and the next—a few won a lot, others lost far more than average. When playing 20 lines there were fewer big winners and fewer players quickly losing a large percentage of their money. We simulated a Gambler’s Ruin scenario whereby players arrived with $100 and made $1 wagers until broke. Again we saw a reduction in the variability among player as the number of lines wagered increased, fewer players lost their entire bankroll quickly, and fewer players had big wins. The bonus wins in Money Storm contribute approximately 24 % to the payback of the game, and our simulations of bonus wins shows that with 20 lines wagered the players spend approximately 11 % of their time in bonus wins. With one line wagered, there are no losses disguised as wins while with 20 lines wagered the majority of hits are losses disguised as wins. Players using multi-line machines can thus tune the characteristics of the machine gambling experience to match their preferred pattern, though most seem in practice to bet on the most possible lines. Our results serve to inform researchers, counsellors, gamblers and others about how slot machines are designed, and the effect that wagering on multiple lines has on short-term and long-term play, bonus wins, and losses disguised as wins.     

Inter‐parent Aggression as a Precursor to Disengagement Coping in Emerging Adulthood: The Buffering Role of Friendship Competence

Using multi‐informant data drawn from a prospective study involving 184 youth, mother‐perpetrated and father‐perpetrated partner aggression during early adolescence (the age of 13) was examined as a predictor of five types of disengagement coping strategies in emerging adulthood (the age of 21): behavioral disengagement, mental disengagement, denial, substance use, and restraint. The ability to develop close friendships, or friendship competence, was examined as a moderator of these links. Results suggest that inter‐parent aggression in early adolescence can predict reliance on disengagement coping 8 years later, but that friendship competence can buffer against the reliance on disengagement coping. Moreover, close friendship competence was not directly related to partner aggression by mothers or fathers, suggesting that friendship competence develops along an independent developmental track and thus may truly serve as a buffer for young adults with a history of exposure to inter‐parent aggression.     

Experiences of Biological Parents and Their Older Children in Out-of-Home Care for the First Time

This article will examine the parenting characteristics and challenges that faced a cohort of families participating in an exploratory qualitative research study. This study sought to describe the experiences and characteristics of parents whose children were placed in the child welfare system in early-to-late adolescence (ages 12–18), thus gaining an understanding of the parenting challenges faced as they were able to maintain their children in their homes for a significant portion of their lives. The families of older youths entering care for the first time described how alcohol and drug abuse impacted their relationships with children, significant others, jobs, and their mental health status. A significant issue that emerged in several of the cases were older children who initiated a report to child welfare themselves.     

‘SUBTERRANEAN PASSAGES OF THOUGHT’: EMPIRE'S INSERTS

Scattered throughout Hardt and Negri's Empire are a number of short sections whose manifesto-like energy contrasts with the relatively expository style of the main text. These passages, modeled after the scholie of Spinoza's Ethics, are meant to suggest new ways of thinking about material already presented, to highlight the affective aspect of the material, and to point to hidden connections among different discursive elements. Several of these which did not appear in the published version of Empire for reasons of space are published here for the first time. The matters touched on are as diverse as those in Empire itself: Totality as a philosophical problem, the gender of biopolitical production, the relationship between genocide and the nationstate, the possibility of hope; the paradoxes of unemployment, the function of fear, postmodern prophecy,Hollywood's imperial fantasy, and the paradoxical relationship between being-against and love that has puzzled and fascinated many of Empire's readers.     

Survival at work: flexibility and adaptability in American corporate culture

Using such business self-help bestsellers as Spencer Johnson’s Who Moved My Cheese?, Harvey Mackay’s Swim With the Sharks Without Being Eaten Alive and Kevin Kelly’s New Rules for the New Economy, this article analyses a recent trend in the American business world’s use of Darwinian discourse: the increasing centrality of two specific traits – flexibility and adaptability – to corporate ‘survival’ in the 1980s, 1990s and today. The article argues that this focus on adaptability and flexibility has two especially troubling implications: individuals may be compelled to adapt ceaselessly, and the problematic idea that one can survive or succeed through sheer individual will may become naturalized.     

Sea change: Santa Barbara and the eruption of corporate social responsibility

Corporate social responsibility (CSR) programs have proliferated among the world's largest corporations. While the lion's share of scholarly attention has been devoted to the competitive advantage of CSR as a branding strategy, very little notice has been taken of CSR's history, particularly the emergence of CSR programs during the politically turbulent l960s and l970s. The paucity of historical attention has led to several distortions, including the failure to recognize CSR's origins as a survivalist reaction to crisis, and the resulting overemphasis of CSR as an unambiguously ethical model of managerial proactive effectiveness. Based on an examination of newspaper records of a politically crystallizing oil spill in the waters off the coast of Santa Barbara, California, and an analysis of CSR's market penetration and rhetoric, this paper offers an alternative framework for reexamining corporate social responsibility.     

The importance of knowing the affective meaning of job demands revisited

This paper starts with the assumption that when people are asked to describe the level of demands they face at work, it cannot be assumed that those demands are necessarily stressful, even if they are rated as strong or high demands. Thirty demand questions were designed for use with a sample of 2,253 public sector employees in Western Australia. As well as rating frequency of demand the respondents were asked to rate their level of dissatisfaction with the demand. For only 16 of the demands was there a correlation high enough to assume that the demand might be a stressor. Having demonstrated this, the rest of the paper compares different ways of combining the two scores to predict the level of psychological distress as measured by the General Health Questionnaire (GHQ12). The results support the claim in the title, that it is important to know the affective meaning of job demands.
