    Can cognitive biases be good for entrepreneurs?

    Purpose While some studies have found that cognitive biases are detrimental to entrepreneurial performance, others have conjectured that cognitive biases may stimulate entrepreneurial action. This study uses a typology of availability and representative heuristics to examine how two patterns of biases affect entrepreneurial performance. Drawing on ideas from cognitive science, this study predicts that various levels of biases in each pattern stimulate entrepreneurial behavior and performance. Design/methodology/approach A profile-deviation approach was employed to analyze data from 253 entrepreneurs and zero-truncated Poisson regression and the zero-truncated negative binomial regression to test hypotheses. Findings This study finds some positive associations between a particular level of cognitive biases in each of the two patterns and entrepreneurial behavior and performance. Results show that the patterns of biases often stimulate and never hurt entrepreneurial behavior and performance. The opposite holds for a lack of cognitive biases, which hurts and never stimulates entrepreneurial behavior and performance. Originality/value This study examines patterns of cognitive biases of entrepreneurs instead of single biases. The study broadens the perspective on the heuristics and cognitive biases of entrepreneurs by examining patterns of biases emanating from the availability and the representativeness heuristic that make a difference for entrepreneurial behavior and performance. The study also brings the "great rationality debate" closer to the entrepreneurship field by showing that a normative rule based on statistics and probability theory does not benefit entrepreneurial behavior and performance

    Knowledge sharing in inter-organisational teams:the role of the advice network and the substitutive role of the formal network in an R&D alliance

    Innovation is about individuals collaborating to share existing knowledge and create new knowledge. Increasingly these collaborations cross organisational boundaries, like in R&D alliances. Many of these alliances are coopetitive, partners cooperate, but also compete with each other. Although knowledge sharing in coopetitive settings has been studied on the firm and the unit level, the micro (individual) level is underresearched. We consider individual alliance-related work performance of alliance members in a (moderately) coopetitive R&D alliance, drawing on social network theory and the organisational coordination perspective. We examine the influence of individual alliance members’ position and level of activity in the alliance advice network on their work performance. We also examine the substitutive role of the alliance formal network, representing the official channels of knowledge sharing. We suggest that individuals’ work performance is better explained by their position in the formal network, rather than in the advice network.</p

    Health items with a novel patient-centered approach provided information for preference-based transplant outcome measure

    Objectives: Patient-reported outcome measures (PROMs) are widely applied to assess perceived health status. To date, no transplant-specific PROM is available for generating a single, standardized score regarding the health status of transplant recipients. The objective of this study is to generate health items for a new patient-centered PROM for organ recipients: the Transplant PROM (TXP). Study Design and Setting: A five-phase, mixed-method approach was applied to identify and select the health items: scoping literature review, expert meetings, focus-group meetings with organ recipients, a special judgmental task within an online survey, and expert meetings for final selection of health items. Results: Based on a previously published scoping literature review, a first round of expert meetings, and a total of four focus-group meetings with kidney, lung, and liver transplant recipients (N = 18), a list of 83 relevant health items relating to post-transplant life was selected. In an online survey, 183 transplant recipients selected the 10 most important health items from this list. After evaluating the frequency of selected health items and combining items that assess closely related or similar concepts in the second round of expert meetings, nine health items were chosen to be included in TXP: fatigue, skin, worry/anxiety, self-reliance, activities, weight, sexuality, stooling, and memory/concentration. Conclusion: The nine TXP health items reflect the most prominent issues transplant recipients experience. The TXP can be administered by means of a mobile phone app

    Using a novel concept to measure outcomes in solid organ recipients provided promising results

    Objectives: Efforts to evaluate the health of solid organ transplant recipients are hampered by the lack of adequate patient-reported outcome measures (PROMs) targeting this group. We developed the Transplant ePROM (TXP), which is based on a novel measurement model and administered through a mobile application to fill this gap. The main objective of this article is to elucidate how we derived the weights for different items, and to report initial empirical results. Study design and setting: The nine health items in the TXP were fatigue, skin, worry, self-reliance, activities, weight, sexuality, stooling, and memory. Via an online survey solid organ recipient participating in the TransplantLines Biobank and Cohort study (NCT03272841) were asked to describe and then compare their own health state with six other health states. Coefficients for item levels were obtained using a conditional logit model. Results: A total of 232 solid organ transplant recipients (mean age: 54 years) participated. The majority (106) were kidney recipients, followed by lung, liver, and heart recipients. Fatigue was the most frequent complaint (54%). The strongest negative coefficients were found for activities and worry, followed by self-reliance and memory. Conclusion: A set of coefficients and values were developed for TXP. The TXP score approximated an optimal health state for the majority of respondents and recipients of different organs reported comparable health states. (c) 2021 The Authors.

    Regional spread of HIV-1 M subtype B in middle-aged patients by random env-C2V4 region sequencing

    Get PDF
    A transmission cluster of HIV-1 M:B was identified in 11 patients with a median age of 52 (range 26–65) in North-East Germany by C2V4 region sequencing of the env gene of HIV-1, who—except of one—were not aware of any risky behaviour. The 10 male and 1 female patients deteriorated immunologically, according to their information made available, within 4 years after a putative HIV acquisition. Nucleic acid sequence analysis showed a R5 virus in all patients and in 7 of 11 a crown motif of the V3 loop, GPGSALFTT, which is found rarely. Analysis of formation of this cluster showed that there is still a huge discrepancy between awareness and behaviour regarding HIV transmission in middle-aged patients, and that a local outbreak can be detected by nucleic acid analysis of the hypervariable env region
