Competition between firms in developing and developed countries

We analyze competition in emerging markets between firms in developing and developed countries from the viewpoint of the boundaries of the firm. Although indigenous firms generally face a disadvantage in technology compared with foreign firms, they have an advantage in marketing as local firms. Moreover, they have opportunities to leave weaker fields to independent specialized firms and use lower wages. On the other hand, foreign firms also have their own advantages and disadvantages for growth. Therefore, entry conditions for indigenous firms can vary greatly depending on the situation. We classify these conditions into eight cases by developing a model and showing each boundary choice for indigenous firms.

Qualitative analysis of critical moments in basketball

The aim of this paper was to know the coach point of view about the critical moment concept in basketball. The methodology used in our research is a qualitative methodology. The instrument used to obtain the data was the semi- structured interviews. There were interviewed 12 ACB league coaches during the 2011/12 season. Results show that incertitude is associated to the critical moment concept. Last minutes of close games and also overtime are identified as critical moment of the game. There is nott any variable in statistics considered by all coaches to determine the critical moment, and they were agree that respecting some game rules is basic to face up the critical moment.

COACHING E MENTORING COMO PRÁTICAS DE COMPARTILHAMENTO DO CONHECIMENTO: ESTUDOS DE CASOS EM EMPRESAS PÚBLICAS PAULISTAS

A pesquisa teve como objetivo geral analisar as principais razões pelas quais as empresas públicas paulistas utilizam coaching e mentoring como práticas de compartilhamento de conhecimento. No ano de 2009, foi instituído pelo governador do Estado de São Paulo, o decreto nº 53.963 que instituiu a Política de Gestão do Conhecimento e Inovação para as empresas públicas. Kuniyoshi e Santos (2007) realizaram uma pesquisa, na qual identificaram práticas e iniciativas de gestão do conhecimento adotadas por algumas empresas, dentre elas, coaching e mentoring. As práticas são processos que necessitam de investimento não somente financeiro, mas de tempo e pessoas adequadas, por serem processos mais complexos, instigam a investigação de ações no contexto organizacional de empresas públicas. Este estudo busca contribuir para o desenvolvimento de estudos na área pública. O método utilizado neste estudo de abordagem qualitativa é do tipo exploratória. O objeto desta pesquisa foram as empresas públicas paulistas, que, atualmente, somam 21. Foi realizado estudo de caso, com entrevista e análise documental em duas destas empresas, A Sabesp, empresa do segmento de saneamento de água e esgoto, teve como objetivo analisar a prática de coaching e, o Instituto de Pesquisa Tecnológicas (IPT), referência nacional em metrologia, teve como objetivo analisar a prática de mentoring. Uma vez que não existem práticas exclusivas à Gestão do Conhecimento, e o sucesso de uma prática está relacionado ao contexto na qual está inserida. No caso da Sabesp, a prática de coaching é utilizada como uma das atividades dentro de dois programas, visando desenvolver o capital humano como força competitiva. O IPT teve como objetivo da aplicação do programa de mentoring, especificamente, o compartilhar conhecimento tácito. Foi constatado que as práticas de coaching e mentoring podem ser utilizadas como recurso capaz de tornar a empresa singular perante as demais, mesmo empresas públicas não tendo foco em competitividade, mas utilizam o conhecimento de forma estratégica para melhorar a qualidade de atendimento à sociedade.

Correlates of the desired family size among Indian communities.

The People of India database of the Anthropological Survey of India documents 631 cultural, ecological, and economic traits of the 4635 communities to which the entire Indian population is assigned. Focusing on 1342 communities of South India, we looked for correlates of low (1 or 2 children) and high (4 or more children) desired family size (DFS) reported as the norm for any given community by key informants. We found 10 cultural and 18 economic traits to be significantly correlated to high DFS and 21 cultural and 9 economic traits to low DFS. The economic traits so identified are compatible with high family size being desired by parents who have little capability of investing in quality of offspring, but whose children contribute economically from an early age. In contrast, communities desiring low family size are part of the modern intensive agriculture/organized industry/services sector and invest heavily in educating their children. A composite index based on 27 economic traits (CEI) has a high predictive value with respect to the DFS for the entire set of 4635 Indian communities. The 31 cultural traits highly correlated to high or low DFS constitute 5 clusters that can be identified as characterizing scheduled tribes, scheduled castes, rural and landless lower castes, urban upper castes, and Moslems. Whereas economic traits have similar influence on DFS within each of these ethnic categories, Moslems demonstrate a significantly higher DFS for lower values of CEI.

Assembly of functional Escherichia coli RNA polymerase containing beta subunit fragments.

The Escherichia coli rpoB gene, which codes for the 1342-residue beta subunit of RNA polymerase (RNAP), contains two dispensable regions centered around codons 300 and 1000. To test whether these regions demarcate domains of the RNAP beta subunit, fragments encoded by segments of rpoB flanking the dispensable regions were individually overexpressed and purified. We show that these beta-subunit polypeptide fragments, when added with purified recombinant beta', sigma, and alpha subunits of RNAP, reconstitute a functional enzyme in vitro. These results demonstrate that the beta subunit is composed of at least three distinct domains and open another avenue for in vitro studies of RNAP assembly and structure.

Do we really know the prevalence of accomodative and nonstrabismic binocular dysfunctions?

Purpose: To determine the scientific evidence about the prevalence of accommodative and nonstrabismic binocular anomalies. Methods: We carried out a systematic review of studies published between 1986 and 2009, analysing the MEDLINE, CINAHL, FRANCIS and PsycINFO databases. We considered admitting those papers related to prevalence in paediatric and adult populations. We identified 660 articles and 10 papers met the inclusion criteria. Results: There is a wide range of prevalence, particularly for accommodative insufficiency (2 %-61.7 %) and convergence insufficiency (2.25 %-33 %). More studies are available for children (7) compared with adults (3). Most of studies examine clinical population (5 studies) with 3 assessed at schools and 1 at University with samples that vary from 65 to 2048 patients. There is great variability regarding the number of diagnostic signs ranging from 1 to 5 clinical signs. We found a relation between the number of clinical signs used and prevalence values for convergence insufficiency although this relationship cannot be confirmed for other conditions. Conclusion: There is a lack of proper epidemiological studies about the prevalence of accommodative and nonstrabismic binocular anomalies. Studies reviewed examine consecutive or selected patients in clinical settings and schools but in any case they are randomized and representative of their populations with no data for general population. The wide discrepancies in prevalence figures are due to both sample population and the lack of uniformity in diagnostic criteria so that it makes difficult to compile results. Biases and limitations of reports determine that prevalence rates offered are only estimations from selected populations.

Is there any evidence for the validity of diagnostic criteria used for accommodative and nonstrabismic binocular dysfunctions?

Purpose: To analyze the diagnostic criteria used in the scientific literature published in the past 25 years for accommodative and nonstrabismic binocular dysfunctions and to explore if the epidemiological analysis of diagnostic validity has been used to propose which clinical criteria should be used for diagnostic purposes. Methods: We carried out a systematic review of papers on accommodative and non-strabic binocular disorders published from 1986 to 2012 analysing the MEDLINE, CINAHL, PsycINFO and FRANCIS databases. We admitted original articles about diagnosis of these anomalies in any population. We identified 839 articles and 12 studies were included. The quality of included articles was assessed using the QUADAS-2 tool. Results: The review shows a wide range of clinical signs and cut-off points between authors. Only 3 studies (regarding accommodative anomalies) assessed diagnostic accuracy of clinical signs. Their results suggest using the accommodative amplitude and monocular accommodative facility for diagnosing accommodative insufficiency and a high positive relative accommodation for accommodative excess. The remaining 9 articles did not analyze diagnostic accuracy, assessing a diagnosis with the criteria the authors considered. We also found differences between studies in the way of considering patients’ symptomatology. 3 studies of 12 analyzed, performed a validation of a symptom survey used for convergence insufficiency. Conclusions: Scientific literature reveals differences between authors according to diagnostic criteria for accommodative and nonstrabismic binocular dysfunctions. Diagnostic accuracy studies show that there is only certain evidence for accommodative conditions. For binocular anomalies there is only evidence about a validated questionnaire for convergence insufficiency with no data of diagnostic accuracy.

Clinical and quality of life data correlation with a single-optic accommodating intraocular lens

Purpose: To examine a single-optic accommodating intraocular lens (IOL) visual performance by correlating IOL implanted eyes’ defocus curve with the intraocular aberrometric profile and the impact on the quality of life (QOL). Methods: Prospective consecutive case series study including a total of 25 eyes of 14 patients with ages ranging between 52 and 79 years old. All cases underwent cataract surgery with implantation of the single-optic accommodating IOL Crystalens HD (Bausch & Lomb). Distance and near visual acuity outcomes, intraocular aberrations, the defocus curve and QOL (NEI VFQ-25) were evaluated 3 months after surgery. Results: A significant improvement in distance visual acuity was found postoperatively (p = 0.02). Mean postoperative LogMAR uncorrected near visual acuity was 0.44 ± 0.23 (20/30). 60% of eyes had a postoperative addition between 0 and 1.5 diopters (D). The defocus curve showed an area of maximum visual acuity for the levels of defocus corresponding to distance and intermediate vision (−1 to +0.5 D). Postoperative intermediate visual acuity correlated significantly some QOL indices (r ≥ 0.51, p ≤ 0.03; difficulty in going down steps or seeing how people react to things that patient says) as well as with J0 component of manifest cylinder. Postoperative distance-corrected near visual acuity correlated significantly with age (r = 0.65, p < 0.01). Conclusions: This accommodating IOL seems to be able to restore the distance visual function as well as to provide an improvement in intermediate and near vision with a significant impact on patient's QOL, although limited by age and astigmatism. Future studies with larger sample sizes should confirm all these trends.

Optic neuritis in pediatric population: A review in current tendencies of diagnosis and management

Optic neuritis is an inflammation of the optic nerve and may be related to different systemic conditions. The clinical presentation of this pathology usually includes sudden loss of visual acuity (VA) which may be unilateral or bilateral, visual field restriction, pain with eye movements, dyschromatopsia, a relative afferent pupillary defect and optic disk swelling. Optic neuritis in children has specific clinical features and a better prognosis than in adulthood. Although usually appears an underlying viral disease, the main concern for practitioners is the relationship of optic neuritis with multiple sclerosis. In addition to the classical techniques as magnetic resonance imaging (MRI), current tendencies of diagnosis for eye practitioners include new imaging devices as optical coherence tomography (OCT), useful to show a thinning of the retinal fibers layer (RFL) after the inflammatory episode. Regarding the management of these patients, short-term intravenous steroid dosages seem to be the best option to treat acute attacks characterized by a very poor bilateral VA.
