Understanding the gender gap in immigrant entrepreneurship: a multi-country study of immigrants’ embeddedness in economic, social, and institutional contexts
Given the rising rate of migration across the globe, immigrant entrepreneurship is more than ever a topic of high theoretical and practical relevance. Immigrant entrepreneurship can offer host societies a win-win situation, generating incomes for immigrant entrepreneurs and contributing to knowledge transfer, innovativeness, and economic growth within the host economy. However, studies reveal that immigrant entrepreneurship is primarily male dominated and our understanding of the drivers and contextual factors that explain the gender gap is limited. Based on the mixed embeddedness approach, this multi-country study investigates the effects of immigrants’ embeddedness in supportive economic, social, and institutional environmental conditions on the gender gap in immigrant entrepreneurship. Our key findings are threefold: First, the results confirm that a gender gap in immigrant entrepreneurship exists. Female immigrants, compared with their male counterparts, are less likely to start and run their own business. Second, the results reveal that female immigrant entrepreneurship is encouraged by a supportive entrepreneurial environment, showing that policy can enhance female immigrant entrepreneurship through supportive conditions. Third, we find the same pattern of results for forced immigrants and opposite results for natives, suggesting that entrepreneurship is a “Plan A” employment strategy for (forced) female immigrants, whereas it is only a “Plan B” employment strategy for female natives
Transition Properties of Low Lying States in Atomic Indium
We present here the results of our relativistic many-body calculations of
various properties of the first six low-lying excited states of indium. The
calculations were performed using the relativistic coupled-cluster method in
the framework of the singles, doubles and partial triples approximation. We
obtain a large lifetime ~10s for the [4p^6]5s^2 5p_{3/2} state, which had not
been known earlier. Our precise results could be used to shed light on the
reliability of the lifetime measurements of the excited states of atomic indium
that we have considered in the present work.Comment: 6 pages, 1 figure and 3 table
Cellular automaton model of precipitation/dissolution coupled with solute transport
Precipitation/dissolution reactions coupled with solute transport are
modelled as a cellular automaton in which solute molecules perform a random
walk on a regular lattice and react according to a local probabilistic rule.
Stationary solid particles dissolve with a certain probability and, provided
solid is already present or the solution is saturated, solute particles have a
probability to precipitate. In our simulation of the dissolution of a solid
block inside uniformly flowing water we obtain solid precipitation downstream
from the original solid edge, in contrast to the standard reaction-transport
equations. The observed effect is the result of fluctuations in solute density
and diminishes when we average over a larger ensemble. The additional
precipitation of solid is accompanied by a substantial reduction in the
relatively small solute concentration. The model is appropriate for the study
of the r\^ole of intrinsic fluctuations in the presence of reaction thresholds
and can be employed to investigate porosity changes associated with the
carbonation of cement.Comment: LaTeX file, 13 pages. To appear in Journal of Statistical Physics

Greater fit and a greater gap: how environmental support for entrepreneurship increases the life satisfaction gap between entrepreneurs and employees
Purpose – This study seeks to understand how national institutional environments contribute to differences in life satisfaction between entrepreneurs and employees.
Design/methodology/approach – Leveraging person–environment fit and institutional theories, and using a sample of more than 70,000 entrepreneurs and employees from 43 countries, the study investigates how the impact of entrepreneurial activity on life satisfaction differs in various environmental contexts. An entrepreneur’s life satisfaction arguably should increase when a high degree of compatibility or fit exists between his or her choice to be an entrepreneur and the informal and formal institutional environment.
Findings – Differences in life satisfaction between entrepreneurs and employees are greater in countries marked by low individualism, high power distance, low uncertainty avoidance, supportive entrepreneurship policies, low commercial profit taxes, and weak worker rights.
Originality/value – This study sheds new light on how entrepreneurial activity affects life satisfaction, contingent on the informal and formal institutions in a country that support entrepreneurship by its residents

Too much of a good thing? On the relationship between CSR and employee work addiction
Recent research highlights the positive effects of organizational CSR engagement on employee outcomes, such as job and life satisfaction, performance, and trust. We argue that the current debate fails to recognize the potential risks associated with CSR. In this study, we focus on the risk of work addiction. We hypothesize that CSR has per se a positive effect on employees and can be classified as a resource. However, we also suggest the existence of an array of unintended negative effects of CSR. Since CSR positively influences an employee’s organizational identification, as well as his or her perception of engaging in meaningful work, which in turn motivates them to work harder while neglecting other spheres of their lives such as private relationships or health, CSR indirectly increases work addiction. Accordingly, organizational identification and work meaningfulness both act as buffering variables in the relationship, thus suppressing the negative effect of CSR on work addiction, which weakens the positive role of CSR in the workplace. Drawing on a sample of 565 Swiss employees taken from the 2017 Swiss Public Value Atlas dataset, our results provide support for our rationale. Our results also provide evidence that the positive indirect effects of organizational CSR engagement on work addiction, via organizational identification and work meaningfulness, become even stronger when employees care for the welfare of the wider public (i.e., the community, nation, or world). Implications for research and practice are discussed
Advances in the Derivation of Northeast Siberian Forest Metrics Using High-Resolution UAV-Based Photogrammetric Point Clouds
Forest structure is a crucial component in the assessment of whether a forest is likely to act as a carbon sink under changing climate. Detailed 3D structural information about the tundra–taiga ecotone of Siberia is mostly missing and still underrepresented in current research due to the remoteness and restricted accessibility. Field based, high-resolution remote sensing can provide important knowledge for the understanding of vegetation properties and dynamics. In this study, we test the applicability of consumer-grade Unmanned Aerial Vehicles (UAVs) for rapid calculation of stand metrics in treeline forests. We reconstructed high-resolution photogrammetric point clouds and derived canopy height models for 10 study sites from NE Chukotka and SW Yakutia. Subsequently, we detected individual tree tops using a variable-window size local maximum filter and applied a marker-controlled watershed segmentation for the delineation of tree crowns. With this, we successfully detected 67.1% of the validation individuals. Simple linear regressions of observed and detected metrics show a better correlation (R2) and lower relative root mean square percentage error (RMSE%) for tree heights (mean R2 = 0.77, mean RMSE% = 18.46%) than for crown diameters (mean R2 = 0.46, mean RMSE% = 24.9%). The comparison between detected and observed tree height distributions revealed that our tree detection method was unable to representatively identify trees 15–20 m to capture homogeneous and representative forest stands. Additionally, we identify sources of omission and commission errors and give recommendations for their mitigation. In summary, the efficiency of the used method depends on the complexity of the forest’s stand structure

Practice rather than preach: cultural practices and female social entrepreneurship
This paper draws on practice theory to argue that the practiced culture of a society and gender interact to create cultured capacities for social entrepreneurship among entrepreneurs. We combine data from the Global Entrepreneurship Monitor (GEM) with the Global Leadership and Organizational Behavior Effectiveness (GLOBE) and World Bank (WB) to identify what cultural practices are most relevant for female entrepreneurs’ practice of social entrepreneurship across 33 countries. Our findings suggest that female entrepreneurs are more likely to engage in social entrepreneurship when cultural practices of power distance, humane orientation, and in-group collectivism are low, and cultural practices of future orientation and uncertainty avoidance are high, when compared to male entrepreneurs

When discrimination is worse, autonomy is key: How women entrepreneurs leverage job autonomy resources to find work–life balance
This article examines the relationship between women entrepreneurs’ job autonomy and work–life balance, with a particular focus on how this relationship might be augmented by environments that discriminate against women, whether socio-economically, institutionally, or culturally. Multisource data pertaining to 5334 women entrepreneurs from 37 countries indicate that their sense of job autonomy increases the likelihood that they feel satisfied with their ability to balance the needs of their work with those of their personal life. This process is particularly prominent when they operate in countries characterized by discriminatory socio-economic and institutional conditions, though a mitigating instead of invigorating effect arises in culturally discriminatory settings. For business ethics scholars and practitioners, these findings indicate how the extent to which women entrepreneurs, seeking to combine professional and private responsibilities, derive benefits from initiatives aimed at enhancing their job-related freedom critically depends on whether they operate in adverse external environments
Entrepreneurs' individual-level resources and social value creation goals : the moderating role of cultural context
Purpose—This study seeks to provide a better understanding of how the interplay of individual-level resources and culture affects entrepreneurs’ propensity to adopt social value creation goals.
Design/methodology/approach—Using a sample of 12,685 entrepreneurs in 35 countries from the Global Entrepreneurship Monitor, this study investigates the main effects of individual-level resources—measured as financial, human, and social capital—on social value creation goals, as well as the moderating effects of the cultural context in which the respective entrepreneur is embedded, on the relationship between individual-level resources and social value creation goals.
Findings—Drawing on the resource-based perspective and Hofstede’s cultural values framework, the results offer empirical evidence that individual-level resources are relevant for predicting the extent to which entrepreneurs emphasise social goals for their business. Furthermore, culture influences the way entrepreneurs allocate their resources toward social value creation.
Originality/value—The study sheds new light on how entrepreneurs’ individual resources influence their willingness to create social value. Moreover, by focusing on the role of culture in the relationship between individual-level resources and social value creation goals, it contributes to social entrepreneurship literature, which has devoted little attention to the interplay of individual characteristics and culture

On how personal values and sustainability conceptions impact students’ sustainability management orientation: evidence from Germany, Indonesia, and the USA
Purpose
This study develops and empirically tests a framework on how personal values and sustainability conceptions affect students’ sustainability management orientation (SMO). An understanding of this connection gives insight into the question whether students are likely to engage in sustainable business practices in their future work.
Design/methodology/approach
A cross-sectional and comparative research design is employed, using survey data of business students from Germany, Indonesia, and the United States (N=475). The proposed mediation models are tested by bootstrap procedures using Hayes’s (2013) PROCESS macro for SPSS.
Findings
Self-transcendence values translate into more nuanced sustainability conceptions since individuals with self-transcendence values are more likely to conceptualize sustainability beyond their own (narrow) self-interests. In turn, the stronger individuals’ sustainability conceptions, the higher the likelihood that they prefer sustainable management practices in their future professional working field.
Research limitations/implications
Implications arise for researchers to investigate the engagement of future managers with different personal value types in sustainability practices and to gain insights into values and sustainability conceptions as a learning outcome. Limitations of this research—for instance, arising from potential common method bias—are discussed.
Practical implications
The findings point to the need to (re-)design appointment processes for management positions in a way that allows taking into account individuals’ personal values and sustainability conceptions. This research may also help firms and higher education institutions to empower their workforce/students to develop more integrated perspectives on sustainability challenges as well as teaching methods that address students’ effective learning outcomes, e.g. their values.
Originality/value
The paper offers a new framework and a cross-country perspective on psychological antecedents of individuals’ sustainability management orientation as an important prerequisite for responsible behavior in the business context
