The use of ethanol from biomass as a gasoline substitute in cars and light trucks is possibly one of the most attractive and feasible alternatives to deal with global warming. As environmental concern grows, many countries are increasing their efforts to consolidate bioethanol processes and supply. The sustainable production of bioethanol requires well planned and reasoned development programs to assure that the many environmental, social and economic concerns related to its use are addressed adequately. The key for making ethanol competitive as an alternative fuel is the ability to produce it from low‐cost biomass. Many countries around the world are working extensively to develop new technologies for ethanol production from biomass, from which the lignocellulosic materials conversion seem to be the most promising one. This paper aims at providing some information about the status of bioethanol production and use around the world.

This paper examines the role of managerial curiosity as a critical factor in determining the future impact of disruptive information technologies in a global organization. Specifically, this paper presents curiosity as a managerial characteristic that plays an important role in identifying disruptive information technologies and facilitating their early adoption. Further, it uses resource‐based theory as a theoretical lens to illustrate how managerial curiosity can be a source of sustained competitive advantage. Finally, it examines the individual decision styles that are best suited in assessing disruptive information technologies.

This article examines how contact with the police led to the death of Michael Brown (an unarmed 18-year-old Black teenager from Ferguson, Missouri, who was shot and killed during an altercation with a police officer). And, how Darren Wilson (the White police officer from the Ferguson Police Department who shot and killed Michael Brown) was portrayed in mainstream newspaper articles covering the story of Brown’s death.

Using both frame analysis and Hall’s framework of discursive domains for organizing and making sense of events in social life, we analyzed news coverage of Brown in three of the top circulating daily newspapers in the US: The New York Times, Los Angeles Times, and The Washington Post. The Lexis Nexis database was used to retrieve a set of newspapers using the search term “Michael Brown.” Articles from the three leading newspapers were collected from the day the event occurred, August 9, 2014, through the end of the year, December 31, 2014.

The news articles used in this study were mostly written with an episodic frame. The articles presenting the socioeconomic background of Brown and Wilson were described as profiles on each individual and the neighborhood they came from, rather than a discussion about where they fell on the economic structure of this country and the larger, upstream forces that might influence those positions. The feelings and attitudes of the reader are also likely to be influenced by details included in the articles and how they were presented.

The findings contribute to the broader literature looking at the relationships between police and Black communities. Public health can play a role in advocating and facilitating programs that build better linkages between police and community. The public health field can take a leadership role in holding the news media accountable when they are engaging in frenetic inaction. Only by having difficult and challenging conversations that examines the upstream causes of violence and deaths like Brown’s, can we make progress in preventing them.

Contemporary organizations are facing an operating environment characterized by volatile, uncertain, complex, ambiguous, and “permanent whitewater.” To sustain high performance in this context, organizations must be able to change and develop as efficiently and effectively as possible. Within organizations, there are actors who catalyze and advance change in this manner; these actors are known as “champions.” Yet the scholar who wishes to conduct research concerning champions of change and organizational development is likely to be met by a highly fragmented literature. Varying notions of champions are scattered throughout extant research, where authors of articles cite different sources when conceptualizing champions; often superficially. Furthermore, many types of highly specific and nuanced non-generalizable champions have proliferated, making it difficult for practitioners and researchers to discover useful findings on how to go about making meaningful changes in their context. The purpose of this study was to address these problems for practitioners and researchers by engendering thoroughness, clarity, and coherence within champion scholarship. This was done by conducting the first comprehensive, critical yet insightful review of the champion literature within the organizational sciences using content analysis to re-conceptualize champions and develop a meaningful typology from which the field can be advanced. The chapter first suggests a return to Schön (1963) as the basis from which to conceptualize champions and, second, offers a typology consisting of 10 meta-champions of organizational change and development – Collaboration, Human Rights, Innovation, Product, Project, Service, Strategic, Sustainability, Technology, and Venture Champions – from which change practice and future research can benefit.

Many jurisdictions fine illegal cartels using penalty guidelines that presume an arbitrary 10% overcharge. This article surveys more than 700 published economic studies and judicial decisions that contain 2,041 quantitative estimates of overcharges of hard-core cartels. The primary findings are: (1) the median average long-run overcharge for all types of cartels over all time periods is 23.0%; (2) the mean average is at least 49%; (3) overcharges reached their zenith in 1891–1945 and have trended downward ever since; (4) 6% of the cartel episodes are zero; (5) median overcharges of international-membership cartels are 38% higher than those of domestic cartels; (6) convicted cartels are on average 19% more effective at raising prices as unpunished cartels; (7) bid-rigging conduct displays 25% lower markups than price-fixing cartels; (8) contemporary cartels targeted by class actions have higher overcharges; and (9) when cartels operate at peak effectiveness, price changes are 60–80% higher than the whole episode. Historical penalty guidelines aimed at optimally deterring cartels are likely to be too low.

This chapter reports on findings from a study that explored the experiences of African American young men who graduated from Du Bois Academy, an all-boys public charter secondary school in the Midwestern region of the United States. The chapter considers issues of African American male persistence and achievement and how they are impacted by school culture. Specifically, the author discusses how school culture can help shape these students’ educational experiences and aspirations. Using student narratives as the guide, a description of how Du Bois Academy successfully engaged these African American male students is provided. The students articulated three critical components of school culture that positively shaped their high achievement and engagement: (a) sense of self, (b) promotion of excellence, and (c) community building. The student narratives provided a frame for promoting positive school culture that enhances the educational experiences and academic aspirations of African American male students.
