RESUMO

This cross-sectional study sought to identify gender differences in individual behavioral attitudes, personal traits, and entrepreneurial education based on planned behavior theory. The Smart partial least squares (PLS) structural equation model and PLS path modeling were used. A survey design was used to collect data from 309 samples using quantitative measures. The model was tested for validity and reliability and showed variance (full, R2 = 58.9% and split, R2 = 62.7% and R2 = 52.7%) in male and female model predictive power, respectively. Subjective norms (SN), personality traits (PT), and entrepreneurial education (EE) significantly impacted the male sample's intention. Females' intentions toward entrepreneurship was less affected by attitude toward behavior (ATB), subjective norms (SN), perceived behavioral control (PBC), and entrepreneurship education (EE). Further, attitudes, social norms, and behavioral controls as mediation variables indicate a significant and positive role of male and female intentions. These findings imply that behavioral beliefs (ATB, PBC, and SN) influence entrepreneurial intention-action translation. The results significantly supported the designed hypotheses and shed light on individual personality traits (PT) and entrepreneurship education (EE) underpinning enterprise intention. The study determined that EE and PT are the strongest predictors of intention, thus highlighting the role of these motives in the entrepreneurial process. This study contributes to the growing body of knowledge on youth entrepreneurs, expands our understanding of entrepreneurship as a practical career choice, and offers a novel account differentiating male and female PT. The drive to evaluate the effects of entrepreneurial intention among budding disparities in Pakistan requires a more profound knowledge of the aspects that endorse entrepreneurship as a choice of profession and enhances youth incentive abilities to engage in entrepreneurial activities based on exploitation.

RESUMO

Dynamic capabilities, resulting from activities that allow conscious and skillful modification of a firm's strategic potential, are seen as one of the key drivers of a firm's value creation, competitive advantage and above-average performance in changing environments. However, little is known about how dynamic capabilities can shape business survival and performance during crises. The research objective of this paper is twofold. First, through a literature review, we seek to identify which first-order dynamic capabilities-managerial decisions under uncertainty-are vital for rapid response to a crisis. Second, we present the results of research carried out among 151 small and medium-sized companies in Poland immediately after the beginning of the economic lockdown (April 2020). The survey that we developed identifies which dynamic capabilities were essential for businesses to survive during this unexpected black swan event. We also present dependence and regression analyses showing the links between the identified dynamic capabilities and value creation, understood as retaining employees and production levels, as well as value capture, understood as maintaining cash flow and current revenues.

RESUMO

Importance: Although there have been signs of increasing interest in entrepreneurship among physicians as well as claims of a paucity of entrepreneurial activity in health care in general, there is little systematic evidence of the extent, type, and characteristics of entrepreneurship by physicians. Physician involvement in entrepreneurship may result in more innovative and financially successful health care companies. Objective: To evaluate the proportion and characteristics of physicians who founded new businesses and the types of businesses that they started. Design, Setting, and Participants: This cross-sectional study was conducted by matching all 33 770 physicians holding a Massachusetts medical license in 2017 with the Massachusetts new business registration records from 1960 to 2017 to identify companies founded by physicians. Data were analyzed from September 2017 to December 2019. Main Outcomes and Measures: The number of physician-founded companies in Massachusetts and the types of businesses as characterized by the stated purpose at the time of founding. Results: Among the 33 770 physicians holding a Massachusetts license in 2017, 13 839 (41.0%) were women and 8029 (23.8%) were international medical graduates; the median year of graduation from medical school was 1994 (interquartile range, 1983-2004). A total of 6494 (19.2%) physicians had founded at least 1 new business, and 831 of the 2448 physicians (33.9%) who graduated from medical school between 1974 and 1978 had founded a business. A total of 9501 companies were founded, of which 6267 (66.0%) were clinical practice, real estate, or practice management companies; 703 companies (7.4%) were in the public interest, including advocacy, public health, and philanthropy; 533 (5.6%) were biotechnology, health care information technology, or medical device companies; and 1759 (18.5%) were other business pursuits. For physician entrepreneurs, the mean (SD) time from medical school graduation to company founding was 20.2 (9.8) years. Regression analysis suggested that female physicians founded companies at lower rates than male physicians (odds ratio [OR], 0.529; 95% CI, 0.494-0.567) and that there was an association between attending a top-10 medical school by National Institutes of Health research funding and starting a clinical practice (OR, 0.687; 95% CI, 0.616-0.766) or biotechnology company (OR, 4.326; 95% CI, 2.951-6.344). Conclusions and Relevance: The findings of this cross-sectional study suggest that physicians may be substantially involved in entrepreneurship, although there may be disparities by sex. Facilitation of physician entrepreneurship by policy makers, educators, and institutions may enhance medical innovation and public health.

RESUMO

The principal questions this research will address are: 1) whether a higher propensity to visit websites of interest to actual or nascent entrepreneurs is associated with higher rates of new firms births in an area; 2) whether a higher propensity to visit websites of interest to those working on design problems is associated with the quality of business in terms of orientations toward design or innovation; and 3) whether a higher propensity to visit websites of interest to those pursuing arts as an avocation is associated with an increased ability to find nonobvious solutions that might be manifest in business quality. The unique data that allow examining these questions were compiled from billions of web hits by geo-located devices. These data are combined with both detailed establishment level data with reliable information on the innovation and design orientation of firms, and a longitudinal census of all establishments with a formal credit relationship in the U.S. The findings confirm that businesses located in areas with a high propensity to visit design and arts avocation websites are more likely to pursue more far ranging innovation and are more likely to integrate design into their innovation processes. Firm birth rates are higher in areas with a high propensity to visit websites of interest to entrepreneurs, and the existence of high growth firms is strongly associated with demonstrated interest in design and arts avocation websites. The possible uses of these nontraditional measures as indicators of economic dynamism are discussed.

RESUMO

Human achievements are often preceded by repeated attempts that fail, but little is known about the mechanisms that govern the dynamics of failure. Here, building on previous research relating to innovation1-7, human dynamics8-11 and learning12-17, we develop a simple one-parameter model that mimics how successful future attempts build on past efforts. Solving this model analytically suggests that a phase transition separates the dynamics of failure into regions of progression or stagnation and predicts that, near the critical threshold, agents who share similar characteristics and learning strategies may experience fundamentally different outcomes following failures. Above the critical point, agents exploit incremental refinements to systematically advance towards success, whereas below it, they explore disjoint opportunities without a pattern of improvement. The model makes several empirically testable predictions, demonstrating that those who eventually succeed and those who do not may initially appear similar, but can be characterized by fundamentally distinct failure dynamics in terms of the efficiency and quality associated with each subsequent attempt. We collected large-scale data from three disparate domains and traced repeated attempts by investigators to obtain National Institutes of Health (NIH) grants to fund their research, innovators to successfully exit their startup ventures, and terrorist organizations to claim casualties in violent attacks. We find broadly consistent empirical support across all three domains, which systematically verifies each prediction of our model. Together, our findings unveil detectable yet previously unknown early signals that enable us to identify failure dynamics that will lead to ultimate success or failure. Given the ubiquitous nature of failure and the paucity of quantitative approaches to understand it, these results represent an initial step towards the deeper understanding of the complex dynamics underlying failure.

RESUMO

Purpose of the study: Amid insufficient retirement savings and the growing need to work longer, it is important to understand why self-employment, especially entrepreneurship, has grown among older households. Older households may have been pushed into entrepreneurship by the growing risks of wage-and-salary employment as wages and jobs have become less stable. Alternatively, older households may have been pulled into entrepreneurship as the associated risks have declined, for instance, due to greater opportunities to diversify income away from risky business income. We examine the economic causes of the rise in entrepreneurship among older households. Design and Methods: We use summary statistics and multinomial logit regressions to analyze the link between economic pressures in wage-and-salary employment, financial strength of entrepreneurship, and the presence and change of entrepreneurship among older households-aged 50 years or older. We use household data from the Federal Reserve's Survey of Consumer Finances from 1989 to 2013. Results: We find little support for the claim that increased economic pressures are correlated with rising entrepreneurship. Instead, our results suggest that the growth of older entrepreneurship is coincident with increasing access to dividend and interest income. We also find some evidence that access to Social Security and other annuity benefits increases the likelihood of self-employment. Implications: Entrepreneurship among older households increasingly correlates with income diversification. Policymakers interested in encouraging more entrepreneurship among older households could consider increased access to income diversification through social insurance.

RESUMO

The literature dealing with health and entrepreneurship has focused on developed countries. We use a sample of almost 5000 business owners and wage-workers from four Caribbean Basin countries to study this relationship. Analyses are performed using data from the Global Entrepreneurship Monitor along with the Visual Analogue Scale of the EQ-5D-5L instrument as an overall health rating. The results show that business owners are healthier than wage-workers, which is in line with the findings from studies in developed countries. Furthermore, better health is associated with a lower likelihood for fear of business failure to be a deterrent to new business formation, a greater likelihood of self-belief in having the skills to run a business, and an increased recognition of start-up business opportunities among wage-workers. These positive associations between health and entrepreneurial perceptions provide new evidence about why less healthy individuals refrain from entrepreneurship. Finally, we find that the healthiest business owners run the companies with the highest growth expectations.

RESUMO

This article examines domestic violence among women who participate in microfinance in Bangladesh. Secondary analysis of survey data from nationally representative Bangladesh Demographic and Health Survey was used to investigate the association between microfinance participation and domestic violence of 4,163 ever-married women between the ages of 18 and 49 years. Outcome measure is experience of domestic violence as measured by a modified Conflict Tactics Scale (CTS) and predictor variables include microfinance, binary indicator of relatively better economic status, autonomy, decision-making power, and demographic variables. The likelihood of experiencing domestic violence was not found to vary with microfinance participation. However, the interaction effect of microfinance and better economic status was found to be significantly associated with domestic violence (9% increased probability). Experience of domestic violence was negatively associated with older age, higher education of the husband, and autonomy. In Bangladesh, microfinance participation may be associated with a higher probability of experiencing domestic violence for women with relatively better economic status, but not for the poorest of the poor.

RESUMO

Taller individuals have on average a higher socio-economic status than shorter individuals. In countries where entrepreneurs have high social status, we may therefore expect that entrepreneurs are taller than wage workers. Using data from the German Socio-Economic Panel (2002-2012), we find that a 1cm increase in an individual's height raises the probability of being self-employed (the most common proxy for entrepreneurship) versus paid employed by 0.15 percentage points. Within the self-employed, the probability of being an employer is increased by 0.10 percentage points as a result of a 1cm increase in height, whereas this increase is 0.05 percentage points for an own-account worker. This result corroborates the higher social status of employers compared to own-account workers. We find a height premium in earnings for self-employed and paid-employed individuals: an additional 1cm in height is associated with a 0.39% increase in hourly earnings for paid employees and a 0.52% increase for self-employed individuals. Our analysis reveals that approximately one third of the height premium in earnings is explained by differences in educational attainment. We also establish the existence of a height premium in terms of work and life satisfaction, which is more pronounced for paid employees than for self-employed individuals.

RESUMO

A melissopalynological analysis of fifty-one natural honey samples (twenty four spring, fifteen summer and twelve winter) collected during 2010-2011 from two east-coastal districts (20(0)20/ to 22(0)11/ N, 82(0)39/ to 87(0)01/ E) of Orissa, India was performed. Out of 37 unifloral samples found 25 were contributed by Apis cerana indica, seven by A. dorsata and the remaining five by A. florea. Out of 14 multifloral samples five were contributed by A. cerana indica, five by A. dorsata and the remaining four by A. florea. Principal component analysis confirmed the palynological classification of the unifloral honey samples. Eighty-two bee-plant taxa belonging to forty four families were recovered. The predominant nectariferous taxa of the spring season were Acanthus ilicifolius, Avicennia marina, Bruguiera gymnorrhiza, Cocos nucifera, Eucalyptus globulus, Phoenix paludosa, Pongamia pinnata, Prosopis juliflora, Sonneratia apetala and Syzygium cumini. In the summer the predominant nectariferous taxa were Borassus flabellifer, C. nucifera, E. globulus, Syzygium cumini, Terminalia arjuna, Aegiceras corniculatum, P. paludosa and Sonneratia apetala while those of the winter were Brassica nigra, Coriandrum sativum, Zizyphus jujuba, Alstonia scholaris, E. globulus and Bruguiera gymnorrhiza. Very low (<0.09) HDE/P for 98% of the samples and absence of toxic palynotaxa assure that these honeys are suitable for human consumption. Quite extended honey flow period with spring and summer as best forage seasons for the honeybees and occurrence of 82% of these honeys with APC Group II, III and IV justify the sustainability of the present study area for establishing moderate to large-scale apicultural entrepreneurship. This should improve the socio-economic status of the people of this region.

RESUMO

Entrepreneurship research is receiving increasing attention in our context, as entrepreneurs are key social agents involved in economic development. We compare the success of the dichotomic logistic regression model and the Bayes simple classifier to predict entrepreneurship, after manipulating the percentage of missing data and the level of categorization in predictors. A sample of undergraduate university students (N = 1230) completed five scales (motivation, attitude towards business creation, obstacles, deficiencies, and training needs) and we found that each of them predicted different aspects of the tendency to business creation. Additionally, our results show that the receiver operating characteristic (ROC) curve is affected by the rate of missing data in both techniques, but logistic regression seems to be more vulnerable when faced with missing data, whereas Bayes nets underperform slightly when categorization has been manipulated. Our study sheds light on the potential entrepreneur profile and we propose to use Bayesian networks as an additional alternative to overcome the weaknesses of logistic regression when missing data are present in applied research.
