Explicitly searching for useful inventions: dynamic relatedness and the costs of connecting versus synthesizing

Inventions combine technological features. When features are barely related, burdensomely broad knowledge is required to identify the situations that they share. When features are overly related, burdensomely broad knowledge is required to identify the situations that distinguish them. Thus, according to my first hypothesis, when features are moderately related, the costs of connecting and costs of synthesizing are cumulatively minimized, and the most useful inventions emerge. I also hypothesize that continued experimentation with a specific set of features is likely to lead to the discovery of decreasingly useful inventions; the earlier-identified connections reflect the more common consumer situations. Covering data from all industries, the empirical analysis provides broad support for the first hypothesis. Regressions to test the second hypothesis are inconclusive when examining industry types individually. Yet, this study represents an exploratory investigation, and future research should test refined hypotheses with more sophisticated data, such as that found in literature-based discovery research

Attitude and acceptance of Covid-19 vaccine amongst medical and dental fraternity - a questionnaire survey

Background. The second wave of Novel Coronavirus disease (COVID-19, SARS-CoV-2) is proving more disastrous than the first because of the new mutant stains. Under these circumstances, vaccination is the only effective solution that can save millions of lives across the globe. Objectives. The present study was conducted to assess the attitude and acceptance/willingness of health care professionals (medical and dental) towards COVID-19 vaccine. Materials and Methods. An online questionnaire survey was conducted among medical and dental professionals working in different hospitals of two states of India. A total of 520 subjects constituted the final sample size. A self-constructed questionnaire (divided into 2 parts) containing 12 questions was administered to obtain information from the subjects regarding their attitude and willingness towards COVID 19 vaccine. Statistical analysis was done using chi-square test and multiple liner regression analysis. Odds ratio with 95% CI were also generated. Statistical significance was set at p≤0.05. Results. Majority of the subjects (67% of dental and 73% of medical) had full confidence on the effectiveness of COVID-19 vaccine. Willingness to get vaccinated was shown by 63% of subjects and 65% had positive attitude towards vaccine. Some subjects (45.5% dental and 48.4% medical) showed concern regarding unforeseen effects of the vaccine. Willingness to get vaccinated was 3.45 higher in subjects who were involved in COVID duties. Subjects giving less preference to natural immunity over vaccine showed more willingness (OR: 2.98) towards getting the vaccine. Conclusion. The findings of the study showed that acceptance and attitude of subjects regarding COVID 19 vaccine was suboptimal as there were various factors which contributed towards subjects’ hesitancy to get vaccinated. There is an utmost need to address various issues regarding vaccine safety to promote high uptake

Do Anglo countries still form a values cluster? Evidence of the complexity of value change

To what extent does the Anglo Cluster remains a cultural cluster in today's managerial and professional workforce? Across six Anglo countries (Australia, Canada, New Zealand, South Africa, U.K., and U.S.), we found significant differences in values orientations (openness to change, conservation, self-enhancement, and self-transcendence values) that challenge the concept of a cohesive Anglo cluster. We also explored the influence of micro-level factors on values orientations and found consistent life-stage and gender differences across countries. We conclude that, even within a group of countries perceived as similar, multi-level analyses are needed to fully capture the essence of values differences across and within countries
