Does mobility increase the productivity of inventors?

Although labor mobility has been recognized as a key mechanism for transferring tacit knowledge, prior research on inventors has so far hardly discussed the impact of a move on inventive performance. Additionally, existing research has neglected the differences in gains from a move between high and lower performing inventors. This paper adds to the current R&D literature by presenting a jointly estimated quantile regression to compare the coefficients of the explanatory variables at different points of the performance distribution. Additionally, dummy variables are used to compare inventive performance prior and in the aftermath of a move. Results reveal that inventors at the upper end of the performance distribution are better able to benefit from a move to draw level with or to overtake non-movers in the post-move period. Whereas at the bottom of the performance distribution a higher level of education has a positive impact on inventive performance, education does not matter significantly at the upper end of the performance distribution. Data for the analysis was derived from a survey of German inventors (N = 3,049).

Group Treatment for Spouse Abuse: Are Women with PTSD Appropriate Participants?

Eighty four abused women seeking therapy with their husbands were accepted into a group treatment program for spouse abuse. In the current study, we evaluated the treatment outcome of those women (n = 27) diagnosed with Posttraumatic Stress Disorder (PTSD). PTSD diagnosis, itself, did not differentiate those women who dropped out of treatment. Results indicated, however, that across all women, avoidance symptomatology significantly differentiated treatment completers from dropouts. Although women with PTSD began treatment in worse condition (lower marital satisfaction, higher depressive symptomatology, greater fear of spouse), post-assessment revealed they achieved positive treatment gains parallel to those of women without PTSD. Women with PTSD improved on each outcome variable measured, including a reduction in fear of spouse. Women with PTSD also did not differentially drop out of either treatment condition (men's/women's versus conjoint groups) which lends support to the appropriateness of conjoint treatment for spouse abuse.     

Injuries of the Head from Backface Deformation of Ballistic Protective Helmets Under Ballistic Impact

Modern ballistic helmets defeat penetrating bullets by energy transfer from the projectile to the helmet, producing helmet deformation. This deformation may cause severe injuries without completely perforating the helmet, termed “behind armor blunt trauma” (BABT). As helmets become lighter, the likelihood of larger helmet backface deformation under ballistic impact increases. To characterize the potential for BABT, seven postmortem human head/neck specimens wearing a ballistic protective helmet were exposed to nonperforating impact, using a 9 mm, full metal jacket, 124 grain bullet with velocities of 400–460 m/s. An increasing trend of injury severity was observed, ranging from simple linear fractures to combinations of linear and depressed fractures. Overall, the ability to identify skull fractures resulting from BABT can be used in forensic investigations. Our results demonstrate a high risk of skull fracture due to BABT and necessitate the prevention of BABT as a design factor in future generations of protective gear.     

HOPE VI: A Promising Vintage?

Public housing policies in distressed communities if they are to succeed, must be based on much more realistic assumptions than they are now. We look at HOPE VI, a public housing policy that not only changes the physical environment, but also social services, job training, work opportunities, transportation, child care and other support services. HOPE VI goes a long way to improving public housing policies for distressed communities.     

On security of collateral in Danish mortgage finance: a formula of property rights,incentives and market mechanisms

Specialized mortgage intermediaries in Denmark have for over 200 years provided owners and buyers of real property wide access to credit. The present paper sets out to explore the safeguards that nurtured development of a robust, market based financing system and a deep mortgage market. Observations are made on the nature of collateral performance in respect to property rights, mortgage law and market development in search of general features of required institutional arrangements. The robustness of the Danish mortgage finance system is largely accredited to the securitization model based on the balance principle that assigns risks and responsibility to market players in a self-disciplinary manner and protected the mortgage banks against cash flow mismatches even during deep crisis, as history attests. It is shown how property registers and effective enforcement have created transparent property rights and practically reduced legal risks of mortgaging to zero. Standardization and scale of economics supported collateral efficiency, as measured in terms of simplicity, transparency, rapidity and costs. The Danish mortgage finance system illustrates the critical role of government in insuring the quality and enforceability of mortgage collateral, and reducing uncertainty for market players throughout the entire process. The paper suggests that sound incentive structures of the securitization model, strong commitment mechanisms and the market mechanisms constituted a complex formula of safeguards that—rather than specific capital coverage requirements—created the preconditions required for a well-functioning mortgage market.     

‘Life is Not Simply Fact’: Aesthetics,Atmosphere and the Neoliberal University

The main objective of this article is to reflect on the way in which a certain neoliberal logic and rationality have become common-sense and to contemplate the possibility of a different aesthetic. The tone or mood of this piece draws on recent work on atmosphere, affect and complexity, which will be used to explore the theme of neoliberalism within the context of the university. In the course of this discussion, I will consider questions such as: how could a different aesthetic influence the university as public space; the curriculum and academic community and friendship? How could a different aesthetic respond to epistemic, ontological and, inherently tied to them, spatial injustice?
