The effects of opportunity motivation and environmental contingencies on market growth strategies of African early-stage entrepreneurs

PurposeThe purpose of this paper is to examine how early-stage entrepreneurs' opportunity motivation impacts their choice of market growth strategies as well as the contingent roles of institutional environments and product market conditions in Africa.Design/methodology/approachThe study employs hierarchical linear modeling to test multilevel models with nested data empirically.FindingsThe findings show that African early-stage entrepreneurs who are opportunity-driven and from countries with strong institutional environments have a higher tendency to adopt market exploration strategies. African early-stage entrepreneurs from countries with strong product market conditions have a higher tendency to adopt market penetration strategies. Further interaction tests show that both contingency conditions, namely institutional environments and product market conditions, moderate the effects of opportunity motivation on market growth strategies of African early-stage entrepreneurs.Practical implicationsThe study shows that policymakers in Africa need to develop flexible, supportive market-related policies based on entrepreneurs' growth paths, institutional environments and product market conditions.Originality/valueThe study is the first to explore multilevel influences on early-stage entrepreneurs' market growth strategies in Africa. It sheds new insights on the entrepreneurial marketing process of early-stage entrepreneurs in Africa.

The Association between Social Participation and Loneliness of the Chinese Older Adults over Time—The Mediating Effect of Social Support

Based on activity theory, this paper employed data from the 2013, 2015, and 2018 waves of the China Health and Retirement Longitudinal Survey, and adopted Hierarchical Linear Modeling and longitudinal mediation analysis to explore the temporal variation characteristics of loneliness and the influence of social participation on loneliness in Chinese Older Adults, as well as the mechanism of them. The study found that loneliness among older adults overall was at a moderate level from 2013 to 2018 and increased over time, which may be related to decreasing social participation from year to year. Decreased social participation was associated with increased loneliness over time (β = −0.060, p < 0.001) and lower social support (β = 0.109, p < 0.001), which was associated with more loneliness (β = −0.098, p < 0.001). In addition, social support played a significant mediating role in the realization of social participation in alleviating loneliness. Social participation can not only directly reduce loneliness, but also reduce loneliness by increasing social support.

DeepNull models non-linear covariate effects to improve phenotypic prediction and association power

Genome-wide association studies (GWASs) examine the association between genotype and phenotype while adjusting for a set of covariates. Although the covariates may have non-linear or interactive effects, due to the challenge of specifying the model, GWAS often neglect such terms. Here we introduce DeepNull, a method that identifies and adjusts for non-linear and interactive covariate effects using a deep neural network. In analyses of simulated and real data, we demonstrate that DeepNull maintains tight control of the type I error while increasing statistical power by up to 20% in the presence of non-linear and interactive effects. Moreover, in the absence of such effects, DeepNull incurs no loss of power. When applied to 10 phenotypes from the UK Biobank (n = 370K), DeepNull discovered more hits (+6%) and loci (+7%), on average, than conventional association analyses, many of which are biologically plausible or have previously been reported. Finally, DeepNull improves upon linear modeling for phenotypic prediction (+23% on average).

Effects of country of origin and importers’ innovativeness in new product trials

Purpose The purpose of this study is to seek to investigate whether and how country of origin (COO) cues – category-country image (CCI) and typicality – and importers’ domain-specific innovativeness (DSI) influence importers’ propensity to the trial new value and premium products. Moreover, it aims to understand whether and how the relationship between the COO effect and industrial purchase intentions is moderated by importers’ propensity to innovate (DSI). Design/methodology/approach International importers completed a quantitative online survey. Factor analysis was used to summarize the latent constructs into orthogonal scores. General linear modeling was applied to the scores to test the hypotheses. Findings The results indicate that importers’ propensity to trial value products is directly influenced by CCI and importers’ DSI. For premium products, typicality has a positive effect on their propensity to trial. Also, CCI and DSI have positive effects on the trial of value products, and the effect is more pronounced than for premium products. Importers’ DSI positively moderates CCI in premium product trials, while it negatively moderates typicality in value products. Practical implications This research provides important managerial implications for practitioners seeking to increase foreign sales, strengthening importers’ product perceived value through COO cues. Exporters should distinguish between value and premium products and, in the selection of international channel partners, they must be attentive to importers’ personal characteristics, such as their propensity to innovate. Exporters selling value products should communicate CCI more clearly and, when targeting innovative importers, opt for atypical products instead of traditional ones. For premium products, which require more complex decisions, exporters should especially underscore product typicality and, with innovative importers, emphasize positive CCI. Originality/value By focusing on the two critical issues of product selection and price levels, this study’s original contribution is to emphasize that, for the same product category, in industrial purchasing decisions of value versus premium products, the COO effect can be different. It also highlights the importance of investigating the COO effect by concentrating on industrial buyers’ personal characteristics, here the DSI of importers, as moderating variables.

When Fathers Feel Socially Constrained to Assume a Role: A Negative Predictor of the Coparental Relationship in Switzerland

Role distribution is a central issue for parents in the transition to parenthood, but little is known about the motivations in fathers to assume a specific role. Differences in work-family balance in each parent may be motivated by an individual choice mutually shared by both partners; however, in many couples, the parents may feel forced to adopt a traditional role distribution, either for financial reasons, or to comply with social expectations about what men and women should do when they are parents. This feeling of being socially constrained to adopt a role distribution that is not congruent with intrinsic motivations can generate dissatisfaction and may jeopardize the development of the interparental relationship. Coparenting refers to the emotional and instrumental support parents bring to each other in their parental tasks. It has been shown to be central in family functioning and a powerful predictor of children’s emotional and cognitive development. In this study, we aimed to assess the extent to which different motivations for role distribution in fathers are predictive of the quality of the coparental relationship. A convenience sample of 144 fathers from the French-speaking part of Switzerland completed online questionnaires about their motivations, coparental relationship, and sociodemographic characteristics. Results showed that the reasons for role distribution were mainly economical, practical, and in order to meet personal expectations. Multivariate general linear modeling showed that role distribution that is constrained to meet social expectations and age were predictive of a less cohesive coparental relationship, whereas a deliberate choice in role distribution was linked to a more cohesive coparental relationship.

Improving well-being with mobile AI-powered Acceptance Commitment Therapy tool: Pragmatic Retrospective Study (Preprint)

BACKGROUND The research and dissemination of smartphones-based apps to deliver coaching and psychological driven intervention had seen a great surge in recent years. Notably, Acceptance Commitment Therapy (ACT) protocols were shown to be uniquely effective in treating symptoms for both depression and anxiety when delivered through smartphone apps. The aim if this study to expand on that work and test the suitability of AI driven intervention delivered directly through popular texting apps. OBJECTIVE This study evaluated our hypothesis that using Kai.ai will result in improved well-being. METHODS A pragmatic retrospective analysis of 2909 users who used Kai.ai on one of the top messaging apps (iMessage, WhatsApp, Discord, Telegram, etc.) Users’ well-being levels were tracked using the WHO-5 well-being questionnaire throughout the engagement with service. Paired sample t-test was used to assess well-being levels pre and post usage, and Hierarchical Linear Modeling was used to examine the change in symptoms over time. RESULTS The median well-being score at the last measurement was better (Mdn = 52) then at the start of the intervention (Mdn = 40), indicating a significant improvement (W=2682927, p<.001, one tailed test). Furthermore, HLM results showed that the improvement in well-being was linearly related to the number of daily messages a user sent (beta =.029, t(81.36)=4, p<.001), as well as the interaction between the number of messages and unique number of days (beta = -.0003, t(81.36)=-2.2, p<.028). CONCLUSIONS mobile based Acceptance Commitment Therapy (ACT) interventions are effective means to improve individuals’ well-being. findings reported in this paper further demonstrate Kai.ai’s great promise in helping individuals improve and maintain high levels of well-being, and thus improve their daily life.

How Job Creativity Requirements Affects Employee Creativity: Evidence From a Across-Level Analysis

The present study adopted the Pygmalion perspective and a multilevel theoretical framework to investigate whether creative process engagement mediates the linkage of job creativity requirement with employee creativity. We examined whether team knowledge sharing moderates the aforementioned relationship. We obtained data from 71 supervisors and their 453 employees from three companies in China and applied Hierarchical Linear Modeling (HLM) version 6.08 to test the cross-level hypotheses. The results revealed that creative process engagement mediates the positive linkage of job creativity requirement with employee creativity. In addition, we observed that team knowledge sharing moderates the relationship among job creativity requirement, employee creativity, and creative process engagement. The practical and theoretical implications of the findings are discussed.
