Racial Wage Disparity in US Cities

This paper estimates the conditional wage gaps between black and white full-time male workers at the metropolitan statistical area (MSA) level using data from the 1990 and 2000 U.S. Censuses. The magnitudes of the wage gaps are found to vary substantially across location. As predicted in Becker's (The economics of discrimination, University of Chicago Press, Chicago, 1957) seminal theory on wage discrimination, we find that the wage gaps are greater in MSAs that have a larger proportion of black workers in the labor force. This is the most consistent result across all specifications and years. We also find the gaps to be greater where there is an overrepresented black population in jail and a more segregated population if the MSA is in the South. The proportion of workers covered by a collective bargaining agreement in the private sector is associated with greater relative black earnings. We find that although the relationship between race and wages has diminished over time as famously suggested in Wilson (The declining significance of race: Blacks and changing American institutions, University of Chicago Press, Chicago, 1978), the significance of race remains.     

Occupational stress in universities: Staff perceptions of the causes,consequences and moderators of stress

In recent years, the Australian university sector has undergone large-scale organizational change, including restructuring, downsizing and government funding cuts. At the same time, research from across the globe reports an alarming increase in the occupational stress experienced by university staff. We report on the first phase of a longitudinal investigation of occupational stress. A total of 22 focus groups were conducted with a representative sample of 178 academic and general staff from 15 Australian universities. The groups focused on understanding staff 's experience of occupational stress, and perceptions of the sources, consequences and moderators of stress. Both general and academic staff reported a dramatic increase in stress during the previous 5 years. As a group, academic staff reported higher levels of stress than general staff. Five major sources of stress were identified including: insufficient funding and resources; work overload; poor management practice; job insecurity; and insufficient recognition and reward. The majority of groups reported that job-related stress was having a deleterious impact on their professional work and personal welfare. Aspects of the work environment (support from co-workers and management, recognition and achievement, high morale, flexible working conditions), and personal coping strategies (stress management techniques, work/ non-work balance, tight role boundaries and lowering standards), were reported to help staff cope with stress. The findings provide a timely insight into the experience of stress within universities.     

Counterfeit Smuggling: Rethinking Paradigms of Diaspora Investment and Trade Facilitation

In this paper we explore the phenomenon of Chinese counterfeits smuggled into Mexico, the world's fourth largest counterfeit market, particularly highlighting the role played by Chinese transnational crime in the production and financing of these illegal exports and the role of the Korean diaspora in the distribution of Chinese counterfeits within Mexico. Based on this case study and the extant literature, we suggest propositions concerning diaspora criminal enterprises and diaspora participants in informal markets that amend current theory concerning two streams of literature — diaspora homeland investment and trade facilitation by diasporas.     

Public Dying: Death in the Media and Jade Goody

Abundant in books, on television, in film, on the internet, and in newspapers and magazines, in the twenty-first century death is hugely accessible. Within recent years, sociologists have responded to this visibility by examining death in the media, including its role and status in popular culture and ‘public mourning’, seen for example following the death of Diana, Princess of Wales in 1997. This article considers a third strand of death in the media that requires sociological attention: public dying. Drawing on the extensive media coverage of reality TV personality Jade Goody’s dying and subsequent death in early 2009, the article examines the way in which Goody’s dying illustrated how it can be commodified.     

Bayesian discrete latent spatial modeling of crack initiation in orthopaedic hip replacement bone cement

In this paper, we propose a spatial model for the initiation of cracks in the bone cement of hip replacement specimens. The failure of hip replacements can be attributed mainly to damage accumulation, consisting of crack initiation and growth, occurring in the cement mantle that interlocks the hip prosthesis and the femur bone. Since crack initiation is an important factor in determining the lifetime of a replacement, the understanding of the reasons for crack initiation is vital in attempting to prolong the life of the hip replacement. The data consist of crack location coordinates from five laboratory experimental models, together with stress measurements. It is known that stress plays a major role in the initiation of cracks, and it is also known that other unmeasurable factors such as air bubbles (pores) in the cement mantle are also influential. We propose an identity-link spatial Poisson regression model for the counts of cracks in discrete regions of the cement, incorporating both the measured (stress), and through a latent process, any unmeasured factors (possibly pores) that may be influential. All analysis is carried out in a Bayesian framework, allowing for the inclusion of prior information obtained from engineers, and parameter estimation for the model is done via Markov chain Monte Carlo techniques.
