This article investigates the role of entrepreneurial social and business networks in the internationalization of hightechnology firms. The authors present case study evidence from born-global information and communication technology firms that shows that established and newly formed social networks can be instrumental in exploring internationalization opportunities. These social networks potentially lead to collaborative cooperation and form part of an entrepreneur's broader business network that facilitates exploitation of internationalization opportunities culminated by successful entry into foreign markets. The study incorporates contemporary literature and offers an internationalization opportunity exploration-exploitation model emanating from the entrepreneur's network configuration. In doing so, it takes a process approach and provides much needed qualitative evidence in network research.

It was found that hip stump ischemia occurs in 5.2% of cases and significantly aggravates 5-year survival. Transcutaneous oxygen tension less than 20 mm Hg is reliable hemodynamic criterion of ischemia.

Introduction: spinal cord injury is a damaging event that affects person's wellbeing and represents a significant societal problem. Traumatic spinal cord injury (TSCI) occurs mostly among young adults and causes severe impairments in daily living activities and functioning. The Work Rehabilitation Questionnaire (WORQ) based on the International Classification of Functioning, Disability and Health was developed recently as an instrument to evaluate functioning in vocational rehabilitation. The evidence of work activities and vocational status of disabled persons in Russia remains almost unstudied, Therefore, the need for Russian version of WORQ has emerged to investigate the social and vocational status of TSCI-patients. Objectives: cross-cultural adaptation of WORQ into Russian; preliminary evaluation of the social and vocational status of patients with TSCI. Material and methods: Russian WORQ (self-reported version) was used to investigate the social and vocational status of the patients with TSCI. Results: more than 80% of participants are not vocationally active; Conclusions: the most severe degree of impairment is not associated with lower rates of employment; female patients with TSCI are more likely to have an active working status.

Background:lower limb amputation (LLA) is a growing problem in the population with and without diabetes mellitus. Monitoring the incidence rates of LLA is important for health care planning and has implications for the future problems of medical and social care.Objective:This study aimed to determine the trends in incidence rates of LLA due to nondiabetic peripheral artery disease in Novokuznetsk, Western Siberia, Russia.Study design:An observational study.Methods:Data on all transtibial and transfemoral amputations performed in inpatient facilities in Novokuznetsk from 1996 to 2019 were derived from the regional Register of patients with limb amputations. The rates were calculated per 100,000 population.Results:A total of 2448 persons with amputations due to nondiabetic peripheral artery disease were included in this study (3191 amputations). The overall incidence rate of LLA in Novokuznetsk increased from 14.6 in 1996 to 30.4 in 2019. The proportion of persons older than 60 years increased from 15.5% in 1996 to 20.3% in 2019.Conclusion:The expected aging of the population and increasing incidence of LLA are relevant issues in Russia. These findings can contribute to improving healthcare services and the development of prevention programs to reverse the alarming trend.
