This paper explores whether one of the most important U.S. policies towards Africa of the past few decades achieved its desired result. In 2000, the United States dropped trade restrictions on a broad list of products through the African Growth and Opportunity Act (AGOA). Since the Act was applied unilaterally and selectively to both countries and products, we estimate the impact with a triple ...

Police investigation units represent a knowledge-intensive and time-critical environment. Knowledge sharing is a key process in investigations. In this paper, we present an empirical study of performance in police investigations. Police investigation units are defined as value shops, where primary detective work is performed. Knowledge sharing is found to have a significant influence on the pol...

We study the phase transition of the coalitional manipulation problem for generalized scoring rules. Previously it has been shown that, under some conditions on the distribution of votes, if the number of manipulators is o ( √ n), where n is the number of voters, then the probability that a random profile is manipulable by the coalition goes to zero as the number of voters goes to infinity, whe...

This report provides an overview of mentoring: the career enhancing and psychosocial functions, the stages of development in the mentoring relationship, and a selective review of the research literature. We argue that the traditional mentoring relationship is difficult to establish and maintain in a military environment for a number of reasons including the rank structure and job environment. T...

among the food products, grains play an important role in the consumption patterns of people, especially in the developing countries. since iran's main source of public dietary energy comes directly from grains, investigating and identifying the determinants of import of these products can be an important step towards food security. most experimental studies consider import of grains as only a ...

Import of tRNA into the mitochondrial matrix of Trypanosoma brucei was reconstituted in vitro. Efficient import required the hydrolysis of externally added ATP and was shown to be a carrier-mediated process depending on proteinaceous receptors on the surface of mitochondria. A partly synthetic tRNA(Tyr) as well as a physiological tRNA(Lys) were imported along the same pathway. Contrary to impor...

Mitochondrial biogenesis is accompanied by an increased expression of components of the protein import machinery, as well as increased import of proteins destined for the matrix. We evaluated the role of the outer membrane receptor Tom20 by varying its expression and measuring changes in the import of malate dehydrogenase (MDH) in differentiating C2C12 muscle cells. Cells transfected with Tom20...

Migration as well as group conflict has occurred throughout history. This thesis examined why in response to internal migration to Mumbai, Bangalore, and Delhi there are varying levels of nativism. The level of nativism was found to be high in Mumbai, medium in Delhi, and low in Bangalore. Anti-migrant sentiment was explained by political competition in Mumbai, class prejudice in Delhi, and an ...

We present a new protocol for reliable data transfer in time-critical applications with zero tolerance for data loss in wireless sensor networks which uses less time and fewer messages in comparison to an established protocol PSFQ. Two key features of our protocol are out-of-sequence forwarding of packets with a priority order for sending different types of messages at nodes and delaying the re...

A major challenge of mobile information technology use in time-critical work settings is to balance the temporal impact on the work practice caused by the technology. This paper presents results from an investigation of the tension between information technology use and temporal aspects in the timecritical work of emergency response. This paper contributes to previous research on the inter-rela...
