Robustness of an aerobic metabolically vinyl chloride degrading bacterial enrichment culture

Degradation of the lower chlorinated ethenes is crucial to the application of natural attenuation or in situ bioremediation on chlorinated ethene contaminated sites. Recently, within mixtures of several chloroethenes as they can occur in contaminated groundwater inhibiting effects on aerobic chloroethene degradation have been shown. The current study demonstrated that metabolic vinyl chloride (VC) degradation by an enrichment culture originating from groundwater was not affected by an equimolar concentration (50 μM) of cis-1,2-dichloroethene (cDCE). Only cDCE concentrations at a ratio of 2.4:1 (initial cDCE to VC concentration) caused minor inhibition of VC degradation. Furthermore, the degradation of VC was not affected by the presence of trans-1,2-dichloroethene (tDCE), 1,1-dichloroethene (1,1-DCE), trichloroethene (TCE), and tetrachloroethene (PCE) in equimolar concentrations (50 μM). Only cDCE and tDCE were cometabolically degraded in small amounts. The VC-degrading culture demonstrated a broad pH tolerance from 5 to 9 with an optimum between 6 and 7. Results also showed that the culture could degrade VC concentrations up to 1,800 μM (110 mg/L).     

German stagnation versus Swedish progression: gender wage gaps in comparison, 1960–2006

This article provides a comparative analysis of the development of the gender wage gap in West Germany and Sweden during the period 1960–2006. Despite the economic similarities including broad social safety nets, the gap has developed differently since 1960. This analysis accounts for micro- and macroeconomic factors and politics and concludes that norms and traditions penetrate institutional settings and ensnare Germany in a cultural trap with regard to gender equality. While Sweden has moved to a two-earner model, German society expects mothers to stay at home. The micro analysis shows that family concerns (e.g. marriage and motherhood) decrease female income in Germany to a far greater extent than do such factors in Sweden, which can be explained in part by deeply held social attitudes.     

“Just a Little Respect”: Effects of a Layoff Agent’s Actions on Employees’ Reactions to a Dismissal Notification Meeting

For several decades, most discussion on financial fraud has centered on the fraud triangle, which has evolved over time through various extensions and re-interpretations. While this has served the profession well, the articulation of the human side of the act is indirect and diffused. To address this limitation, this research develops a model to explain the role of human desires, intentions, and actions in indulgence of, or resistance to, the act of financial fraud. Evidence from religion, philosophy, sociology, neurology, behavioral economics, and social psychology is integrated to develop and support an alternative fraud model, called the disposition-based fraud model (DFM). To articulate the model, its two primary components, disposition and temptation, are further developed and extended. Although the DFM is generally applicable to any act of fraud, this paper focuses on executive fraud. The similarities and differences between the DFM and extant fraud models are discussed. Importantly, in light of the DFM, a re-interpretation of the fraud triangle is made to improve our understanding of the human element in it. Additionally, potential implications of the model for corporate governance are discussed, suggestions for further research are offered, and the DFM’s strengths and limitations are noted.

Business model innovation in strategic alliances: a multi‐layer perspective

Business model innovation (BMI) has recently become a topic of interest for research as well as corporate practice. However, we lack specific insights into actors, drivers, and different forms of BMI as the concept is by now mainly addressed in a very general way. In this paper, we analyze how BMI takes place in strategic alliances with the focus of enhancing the recent knowledge about BMI by developing a concept that links firm‐level BMI with alliance‐driven innovation of business models. Against the background of an in‐depth explorative qualitative study, we shed light on the basic nature business model innovation alliances (BMIA) and their effects on both, alliance level and firm level. We develop a process model of BMIA that is the first model providing a holistic picture of this particular type of BMI. Our findings allow for deep insights into BMI processes in incumbent companies and uncover in detail the importance of boundary spanning activities in this realm. By providing these insights, we pave the ground for a new stream of BMI research that focuses on the in‐depth understanding of the role of collaboration and network effects in recent BMI processes. In addition, we show practical benefits for partners in BMI alliances. These insights may help to overcome the traditional fear of negative effects that is still very often prevalent in companies when it comes to issues of partnering with firm external players in strategic issues.

Growth Miracle or Endangered Development? Vested Interests,Policy-Making,and Economic Development in the Dominican Republic

The Dominican Republic is often considered among the most successful developing countries, based primarily on its high and relatively sustained growth rates over the last two decades. On the other hand, indicators of human and social development, healthcare, and education have been particularly poor. I argue that the polarization of economic power plays an important role for this development. Furthermore, I analyze the structure of the Dominican economy in order to show that the country has relied on tourism, services, and special economic zones to obtain relatively high growth rates. These activities do not require high-skilled labor and will not allow the economy to generate high incomes for the population, but benefit a few families who control most conglomerates. In turn, this explains low investment in education and social spending, as well as low taxation rates.
