Entrepreneurship in Emerging Economies: Where Are We Today and Where Should the Research Go in the Future

ENTREPRENEURSHIP THEORY AND PRACTICE, Issue 1 2008
Garry D. Bruton
Emerging economies are characterized by an increasing market orientation and an expanding economic foundation. The success of many of these economies is such that they are rapidly becoming major economic forces in the world. Entrepreneurship plays a key role in this economic development. Yet to date, little is known about entrepreneurship in emerging economies. This introductory article to the special issue on entrepreneurship in emerging economies examines the literature that exists to date in this important domain. It then reviews the research that was generated as part of this special issue on this topic. The article concludes with a discussion of the critical future research needs in this area. [source]


Comparison of seven-subtest and Satz-Mogel short forms of the WAIS-III

JOURNAL OF CLINICAL PSYCHOLOGY, Issue 7 2002
Joseph F. Kulas
Intellectual functioning remains an important domain of functioning to be measured. To reduce the lengthy administration time, numerous short forms of the WAIS-III have been devised. The present study aimed to compare two methods of applying short forms of the WAIS-3 within a clinical population. The results revealed that both item-reduced and selected subtest short forms provide excellent predictions of full administration WAIS-3 summary and index scores. The Satz-Mogel short form appeared to provide higher predictive power than the seven-subtest short forms and accounted for a higher number of cases within 6 points of the obtained scores from the full administration. However, the Satz-Mogel short form was inferior to the seven-subtest short forms in terms of the reliability of the index and summary IQ scores. As found in previous research, a trade-off occurs between the predictive power and the reliability of a short form. © 2002 Wiley Periodicals, Inc. J Clin Psychol 58: 773-782, 2002. [source]


Research Methods in the Leading Small Business,Entrepreneurship Journals: A Critical Review with Recommendations for Future Research,

JOURNAL OF SMALL BUSINESS MANAGEMENT, Issue 3 2009
Michael R. Mullen
Small business and entrepreneurship scholars have made significant progress toward advancing the field and gaining recognition as an important domain of scientific inquiry. However, the authors suggest that a strong methodological foundation built on state-of-the-art research technologies is necessary to support further paradigmatic growth and maturation. Using Chandler and Lyon's study as a benchmark for research methods through the 1990s, the study critiques research methodologies used by small business and entrepreneurship researchers over the ensuing years. The analysis includes all 665 papers published between 2001 and February of 2008 in the Journal of Small Business Management, Journal of Business Venturing, and Entrepreneurship Theory and Practice. The research outlines key methodological issues, assesses recent methodological practice, identifies current trends, and offers recommendations for researchers in adopting existing and emerging research technologies.

Detection of a novel silent deletion, a missense mutation and a nonsense mutation in TCOF1

PEDIATRICS INTERNATIONAL, Issue 6 2008
Hirotaka Fujioka
Abstract Background: Treacher Collins syndrome (TCS) is a disorder of craniofacial development, that is caused by mutations in the TCOF1 gene. TCS is inherited as an autosomal dominant trait, and haploinsufficiency of the TCOF1 gene product treacle is proposed to be etiologically involved. Methods: Mutational analysis of the TCOF1 gene was done in 10 patients diagnosed with TCS using single-strand conformation polymorphism and direct sequencing. Results: Among these 10 patients, a novel 9 bp deletion was found, together with a previously reported 2 bp deletion, a novel missense mutation and a novel nonsense mutation in three different families. Familial studies allowed judgment of whether these abnormal findings were responsible for the TCS phenotype, or not. The 9 bp deletion of three amino acids Lys-Glu-Lys (1378,1380), which was located in the nuclear localization domain of treacle, seemed not essential for the treacle function. In contrast, the novel mutation of Ala26Val is considered to affect the LisH domain, an important domain of treacle. All of the mutations thus far detected in exon 5 have resulted in frameshift, but a nonsense mutation was detected (Lys159Stop). Conclusion: The information obtained in the present study provides additional insights into the functional domains of treacle. [source]


Cyclic olefin homopolymer-based microfluidics for protein crystallization and in situ X-ray diffraction

ACTA CRYSTALLOGRAPHICA SECTION D, Issue 9 2009
Soheila Emamzadah
Microfluidics is a promising technology for the rapid identification of protein crystallization conditions. However, most of the existing systems utilize silicone elastomers as the chip material which, despite its many benefits, is highly permeable to water vapour. This limits the time available for protein crystallization to less than a week. Here, the use of a cyclic olefin homopolymer-based microfluidics system for protein crystallization and in situ X-ray diffraction is described. Liquid handling in this system is performed in 2,mm thin transparent cards which contain 500 chambers, each with a volume of 320,nl. Microbatch, vapour-diffusion and free-interface diffusion protocols for protein crystallization were implemented and crystals were obtained of a number of proteins, including chicken lysozyme, bovine trypsin, a human p53 protein containing both the DNA-binding and oligomerization domains bound to DNA and a functionally important domain of Arabidopsis Morpheus' molecule 1 (MOM1). The latter two polypeptides have not been crystallized previously. For X-ray diffraction analysis, either the cards were opened to allow mounting of the crystals on loops or the crystals were exposed to X-rays in situ. For lysozyme, an entire X-ray diffraction data set at 1.5,Ĺ resolution was collected without removing the crystal from the card. Thus, cyclic olefin homopolymer-based microfluidics systems have the potential to further automate protein crystallization and structural genomics efforts. [source]


Knowledge Translation in International Emergency Medical Care

ACADEMIC EMERGENCY MEDICINE, Issue 11 2007
L. Kristian Arnold MD
More than 90% of the world population receives emergency medical care from different types of practitioners with little or no specific training in the field and with variable guidance and oversight. Emergency medical care is being recognized by actively practicing physicians around the world as an increasingly important domain in the overall health services package for a community. The know-do gap is well recognized as a major impediment to high-quality health care in much of the world. Knowledge translation principles for application in this highly varied young domain will require investigation of numerous aspects of the knowledge synthesis, exchange, and application domains in order to bring the greatest benefit of both explicit and tacit knowledge to increasing numbers of the world's population. This article reviews some of the issues particular to knowledge development and transfer in the international domain. The authors present a set of research proposals developed from a several-month online discussion among practitioners and teachers of emergency medical care in 16 countries from around the globe and from all economic strata, aimed at improving the flow of knowledge from developers and repositories of knowledge to the front lines of clinical care.

The CHAP domain of Cse functions as an endopeptidase that acts at mature septa to promote Streptococcus thermophilus cell separation

MOLECULAR MICROBIOLOGY, Issue 5 2009
Séverine Layec
Summary Cell separation is dependent on cell wall hydrolases that cleave the peptidoglycan shared between daughter cells. In Streptococcus thermophilus, this step is performed by the Cse protein whose depletion resulted in the formation of extremely long chains of cells. Cse, a natural chimeric enzyme created by domain shuffling, carries at least two important domains for its activity: the LysM expected to be responsible for the cell wall-binding and the CHAP domain predicted to contain the active centre. Accordingly, the localization of Cse on S. thermophilus cell surface has been undertaken by immunogold electron and immunofluorescence microscopies using of antibodies raised against the N-terminal end of this protein. Immunolocalization shows the presence of the Cse protein at mature septa. Moreover, the CHAP domain of Cse exhibits a cell wall lytic activity in zymograms performed with cell walls of Micrococcus lysodeikticus, Bacillus subtilis and S. thermophilus. Additionally, RP-HPLC analysis of muropeptides released from B. subtilis and S. thermophilus cell wall after digestion with the CHAP domain shows that Cse is an endopeptidase. Altogether, these results suggest that Cse is a cell wall hydrolase involved in daughter cell separation of S. thermophilus. [source]


Older and Younger Adults in Pain Management Programs in the United States: Differences and Similarities

PAIN MEDICINE, Issue 2 2006
Harriët M. Wittink PhD
ABSTRACT Objectives., 1) To investigate health status of older (,60 years) and younger adults (<60 years) with chronic pain and to separately compare that with existing normative data; and 2) to examine more fully differences in health status between younger and older adults with chronic pain and explore their geographic variation across three multidisciplinary pain programs in the Pacific, Mountain, and New England regions of the United States. Design., We performed a cross-sectional analysis. Patients., Initial assessments of 6,147 patients dating from January 1998 to January 2003 were used. Outcomes Measures., We used the Treatment Outcomes of Pain Survey (TOPS), a disease-specific instrument that includes the Short Form-36. Results., The health status of the older pain patients in terms of their actual scores was comparable with that of younger pain patients across the three sites. Health status is impaired to a lesser degree in older than in younger adults with chronic pain as compared with normative adults. Statistically significant differences were found in a number of domains of the TOPS. Older adults with chronic pain present with pain intensity similar to that of younger patients with chronic pain, but report better mental health (P < 0.002), less fear-avoidance (P < 0.05), less passive coping (P < 0.0001), more life control (P < 0.05), and more lower body physical limitations (P < 0.005) than younger patients with chronic pain. Conclusions., Older adults with chronic pain differ in a number of important domains from younger adults with chronic pain: overall the former present with greater physical, and less psychosocial impairment.
