Competitive bidding — The probability of winning

A company bidding by sealed tender needs to know the relationship between their bid price and their chances of winning the contract. Previously published models for computing the probability of winning are examined and found to be inaccurate. The problem is reformulated, and a new general predictive model for computing the probability of winning is developed. The method of computation is illustrated by a simple worked example.     

Persistent Complications of Child Sexual Abuse: Sexually Compulsive Behaviors,Attachment, and Emotions

ABSTRACT

Child sexual abuse has the potential to cause distress for the victim across the lifespan. Romantic relationships may be particularly difficult for victims of child sexual abuse. This retrospective study examined differences in adult romantic attachment, sexually compulsive behaviors, and emotion regulation by history of child sexual abuse in a large, nonclinical sample. Those with a history of child sexual abuse reported more attachment anxiety in romantic relationships and engaged in more sexually compulsive behaviors. Overall, males displayed more sexually compulsive behaviors than females regardless of history of sexual abuse. Males with a history of sexual abuse displayed the greatest number of sexually compulsive behaviors. Surprisingly, no differences were observed in emotion regulation or attachment avoidant behaviors by history of child sexual abuse. Future research should seek to replicate current findings and examine emotion regulation difficulties experienced as a result of trauma.     

Productivity of highly skilled immigrants: economists in the postwar period

Prior work finds declining immigrant quality in the postwar period that is linked to source-country and skill-composition changes associated with the 1965 Immigration Act. This paper uses a unique panel of foreign- and native-born American Economic Association members to show that the highly skilled experienced a similar shift away from European migrants toward those from Asia. However, the findings do not indicate that this change in source-country composition has been accompanied by a decline in quality; rather, the most recent cohorts of foreign-born economists appear to be more productive than their native counterparts.     

Rolling with the shakes: an insight into teenagers’ perceptions of recovery after the Canterbury earthquakes

Natural disasters are harmful worldwide events that inflict multiple psychosocial impacts on disaster-exposed individuals. A significant proportion of affected individuals are teenagers (13–18 years old) who, compared with adults, have been historically overlooked in disaster research. The literature is particularly sparse concerning teenagers’ recovery from natural disasters, specifically what recovery means to them and the contributing factors towards their positive recovery. Therefore, the aim of the current study was to gain deeper insight into this largely unexplored area by conducting five focus groups with teenagers (16–18 years) who experienced at least one of the Canterbury, New Zealand, earthquakes since and including the initial September 2010 earthquake. This study directly asked teenagers about their recovery over the three years after the initial earthquakes, with data being analysed using thematic analysis. Two main themes were identified: (1) perceptions of recovery, with three sub-themes (i) knowledge and being less frightened, (ii) talking about the earthquakes and (iii) shift in perspectives; and (2) contributing factors to recovery, with three sub-themes (i) participation in the community response, (ii) returning to school and (iii) the rebuild of Christchurch. These factors provide insight into how we can better support the recovery process for disaster-exposed teenagers to reduce long-term distress.     

A common-features analysis of Amsterdam and London financial markets during the eighteenth century

We examine the financial linkage between the London and Amsterdam financial markets using stock prices recorded in each market over the period 1723-94 in conjunction with tests for common trends, cycles, and regime shifts. These tests reveal a surprising degree of integration between the markets as their prices move together in both the short and long run. Moreover, shocks to the assets translate quickly and accurately between markets. It also appears that Dutch investment did not destabilize London markets and stock prices in London were the primary determinant of prices in Amsterdam.     

Life change and spirituality among a college student cohort

OBJECTIVE: Because college marks a time when life-change is typically high, the authors designed this study to determine whether life-change was related to degree of spirituality, the "directing" component of health, among a college student cohort. PARTICIPANTS AND METHODS: The sample group, consisting of 180 northeastern US undergraduate college students, completed the 48-item Life Attitude Profile-Revised (LAP-R) and the Schedule of Recent Experience (SRE) in the fall semester of 2004. RESULTS: Findings indicate that college students who reported experiencing higher levels of life change, both positive and negative, also scored lower on spirituality. Nevertheless, these students had scores indicative of a higher desire to find spirituality, even though their motivation to do so was low. CONCLUSIONS: Although life changes among college students likely will remain high, lower spirituality can be enhanced; therefore, interested health educators are encouraged to help students increase their degree of spirituality.     

Improving homeless persons' utilisation of primary care: lessons to be learned from an outreach programme in The Netherlands

Elissen AMJ, Van Raak AJA, Derckx EWCC, Vrijhoef HJM. Improving homeless persons' utilisation of primary care: lessons to be learned from an outreach programme in The Netherlands Faced with rising homelessness, countries around the world are in need of innovative approaches to caring for those without shelter, who, more often than not, suffer from severe health problems. We conducted a case study of an innovative Dutch Primary Care for the Homeless (PCH) programme to gain insight into clients' demographic characteristics, health problems and service use, and to develop an explanation for its success in increasing the latter. Our analyses are based on a combination of quantitative and qualitative data. The results of the study suggest that the success of the PCH programme can be explained by the providers' pragmatism and will to adapt their mode of care provision to the behavioural patterns and needs of their homeless clients.     

Counselors' Perceived Person–Environment Fit and Career Satisfaction

This correlational study examined the relationship between career satisfaction and person–organization, demands–abilities, and needs–supplies fit with counselors (N= 464) using the Perceived Job Fit instrument ( Cable & DeRue, 2002 ) and a scale of career satisfaction adapted from the Adult Career Concerns Inventory ( Super, Thompson, Lindeman, Myers, & Jordaan, 1988 ). Using a linear, multiple regression analysis, the authors found that person–organization fit (p= .01) and needs–supplies fit (p= .00) were both positively related to career satisfaction and that there was no relationship between demands–abilities fit and career satisfaction.     

The New Zealand Refugee Resettlement Strategy: implications for identity,acculturation and civic participation

The process of resettlement as a refugee often involves adapting to, and reconciling with, a new social reality. The complexities associated with acculturation across age, gender and family dynamics are navigated within greater social contexts that may encourage or hinder the processes of adjustment and settlement. This paper addresses the recent New Zealand Refugee Resettlement Strategy in light of contemporary theoretical developments with regard to the segmented assimilation thesis and the forms of social capital that, when available, may be mobilised to help refugee-background individuals, families and communities to forge new routes for participation and belonging. In particular, we examine the strategy and its five main goals of self-sufficiency, participation, health and well-being, education and housing as these relate to the possibilities and tensions at play in the wider acculturation experiences of New Zealand's diverse refugee populations.
