This study examines the relationship among owner–managers, business model innovation, and competition. We present a newly constructed dataset of 111 new firms that launched electronic trading platforms (business model innovations) in the US and European bond markets between 1995 and 2004. We contribute to the emerging literature on business model innovation by integrating effectuation theory with the Austrian school's view of competition as a discovery process to examine the role of the entrepreneur in business model design. Our findings reveal that the presence of entrepreneurs as owner–managers positively influences the degree of innovation: this relationship is stronger in less competitive environments but is weaker (and may even reverse) in highly competitive environments. We discuss implications for theory and for entrepreneurs in influencing the degree of business model innovation, and suggest future directions for research.
Sustainability is increasingly concerned with the complex interactions between nature and society, and we need to seek solutions towards the challenges that threaten humanity's collective wellbeing. Towards this end, it is critical to advance the application of research examining the dynamic interactions of the components of complex social-ecological systems and their emerging properties. A key research area is on advancing tools and strategies relevant to the evaluation and strengthening of resilience. Redundancy, diversity, and modularity are important characteristics of resilience with a high potential for application in various critical social-ecological systems. This paper provides a critical overview of the theoretical underpinnings of modularity and redundancy and their application in measuring resilience of trade networks with implications for public policy and institutional design.
Background: Hepatitis B virus is transmitted by body fluids, such as blood and serum. Sexual transmission, vertical transmission, and unsafe injections, including intravenous drug use, are the most common routes of infection for Hepatitis B infection. Medical students have a very important role in preventing the disease by improving the disease knowledge among themselves and the patients they will eventually treat.Methods: A cross sectional study was conducted to assess the KAP among medical students of the first three academic years regarding hepatitis B virus infection. The sample size was 222 students. Data were collected from 230 students using a semi structured questionnaire and analyzed using SPSS v20.Results: Among 230 medical students, 79.1% students had good knowledge about hepatitis B whereas 84.3% of the respondents had the right attitude towards hepatitis B. The practice component was low with only 44.8% of the respondents having correct practice regarding hepatitis B infection.Conclusions: Although the knowledge and attitude regarding hepatitis B infection is high, the practice levels are low indicating the need to encourage proper practices among the medical students.
Background: Global warming is a phenomenon of an increase in the earth’s temperature. It leads to an environmental, as well as social loss, which has shown an upward trend since the industrial revolution. Greenhouse gases have been showing catastrophic consequences as well. This study aims to assess the knowledge, attitude and practice among students on the environment so as to discover the gaps and take steps to curb them.Methods: A cross sectional study was conducted among 10th grade high school students. Purposive sampling was done. A pre-tested, semi-structured and self- administered questionnaire was used to collect data. The data was analyzed using SPSS V2.0.Results: In this study, 48% of the students were boys and the remaining 52% were girls. A majority of the students were Hindu and belonged to the age group 15-16 years. A hundred percent of the students showed concern regarding the degrading environment. 85% agreed to fact that it can be restored by cumulative efforts. Everyone regarded the sun as the ultimate source of energy. The attitude on protecting the environment was high among the majority of the students. 50% of the students save electricity when not needed. 69% of the students had good knowledge, 65% had a good attitude and 53% had a poor level of practice concerning the environment.Conclusions: In light of the scarcity of adequate literature this study was able to identify gaps among students. Appropriate measures are needed to strengthen their knowledge and attitude and improve their practice.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
