Exploring the role of individual level and firm level dynamic capabilities in SMEs’ internationalization

This paper presents a multi-level model that examines the impact of dynamic capabilities on the internationalization of SMEs while taking into account the interactions among them. The purpose of the research is to understand the applicability of dynamic capabilities at the individual and the firm level to the SME internationalization process in developing country context and to assess to what extent a firm’s asset position and individual level dynamic capabilities influence the generation of firm level dynamic capabilities in SMEs. First, the dynamic capabilities theory was theoretically linked to the internationalization phenomenon. The relationships among firm-level dynamic capabilities, individual-level dynamic capabilities (owner specific dynamic capabilities), and internationalization were identified. The research framework and hypotheses were developed and empirically tested with 197 SMEs. The findings established that owner-specific dynamic capabilities have a positive influence on both firm dynamic capabilities and internationalization, and firm dynamic capabilities positively influence internationalization. It was also found that the market assets position measured as perceptual environmental dynamism positively influenced firm dynamic capabilities but structural and reputational asset positions of SMEs did not influence generation of firm dynamic capabilities. Moreover, firm dynamic capabilities had a mediation effect in the relationship between owner-specific dynamic capabilities and internationalization. Theoretically, this confirms the relevance of dynamic capability theory to internationalization and the possibility of integrating existing internationalization theories. Entrepreneurs, SME managers, and policy-makers could gain valuable insights on how entrepreneur and firm capabilities lead to better international prospects from this outcome

Effects of Once-Weekly Exenatide on Cardiovascular Outcomes in Type 2 Diabetes.

Abstract BACKGROUND: The cardiovascular effects of adding once-weekly treatment with exenatide to usual care in patients with type 2 diabetes are unknown. METHODS: We randomly assigned patients with type 2 diabetes, with or without previous cardiovascular disease, to receive subcutaneous injections of extended-release exenatide at a dose of 2 mg or matching placebo once weekly. The primary composite outcome was the first occurrence of death from cardiovascular causes, nonfatal myocardial infarction, or nonfatal stroke. The coprimary hypotheses were that exenatide, administered once weekly, would be noninferior to placebo with respect to safety and superior to placebo with respect to efficacy. RESULTS: In all, 14,752 patients (of whom 10,782 [73.1%] had previous cardiovascular disease) were followed for a median of 3.2 years (interquartile range, 2.2 to 4.4). A primary composite outcome event occurred in 839 of 7356 patients (11.4%; 3.7 events per 100 person-years) in the exenatide group and in 905 of 7396 patients (12.2%; 4.0 events per 100 person-years) in the placebo group (hazard ratio, 0.91; 95% confidence interval [CI], 0.83 to 1.00), with the intention-to-treat analysis indicating that exenatide, administered once weekly, was noninferior to placebo with respect to safety (P<0.001 for noninferiority) but was not superior to placebo with respect to efficacy (P=0.06 for superiority). The rates of death from cardiovascular causes, fatal or nonfatal myocardial infarction, fatal or nonfatal stroke, hospitalization for heart failure, and hospitalization for acute coronary syndrome, and the incidence of acute pancreatitis, pancreatic cancer, medullary thyroid carcinoma, and serious adverse events did not differ significantly between the two groups. CONCLUSIONS: Among patients with type 2 diabetes with or without previous cardiovascular disease, the incidence of major adverse cardiovascular events did not differ significantly between patients who received exenatide and those who received placebo.

INHIBITION OF LENS ALDOSE REDUCTASE BY BIFLAVONES FROM OURATEA-SPECTABILIS

Two biflavonoids were isolated from the EtOH extract from leaves of Ouratea spectabilis. Their structures were established to be the novel 6,6''-bigenkwanin and 7,7''-dimethoxyagathisflavone on the basis of spectroscopic data. The inhibition of bovine lens aldose reductase exerted by these biflavones has been studied

Conjugal amyotrophic lateral sclerosis in Brazil Esclerose lateral amiotrófica em casais no Brasil

The origin of amyotrophic lateral sclerosis (ALS) remains unknown, although it seems to be multifactorial. The role of environmental factors has been frequently investigated and suspicion of its influence can be obtained when clusters of a rare disease are described. OBJECTIVE: To describe conjugal cases of ALS in Brazil. METHOD: We describe 2 couples in which both spouses were affected by ALS. Both couples had lived in southeast Brazil and were married for at least 20 years. RESULTS: There was a great variability in clinical presentation of ALS in our patients. In both couples the interval between disease onsets was short. No precise environmental factors could be identified at the origin of these conjugal cases. CONCLUSION: The occurrence of ALS in couples living in the same area may be epidemiologically important, but we cannot exclude that cases may be due to a chance association.<br>A origem da esclerose lateral amiotrófica (ELA) permanece desconhecida. O papel de fatores ambientais tem sido freqüentemente investigado e a suspeição de sua influência pode ser obtida quando são descritas salvas de casos de uma doença rara. OBJETIVO: Descrever casos de ELA em casais no Brasil. MÉTODO: Apresentamos dois casais em que ambos os cônjuges forma acometidos pela ELA. Ambos os casais residiram na região sudeste do Brasil e estiveram casados por pelo menos 20 anos. RESULTADOS: Houve grande variabilidade na apresentação clínica da ELA em nossos pacientes. Em ambos os casais, o intervalo de início da doença foi curto. Nenhum fator ambiental foi identificado na etiologia destes casos conjugais. CONCLUSÃO: A ocorrência de ELA em casais que habitam a mesma região pode ser epidemiologicamente importante, mas não podemos excluir que estes casos tenham sido mera associação
