Abstract
Purpose
The purpose of this paper is to explore how cohesive/diverse networks affect entrepreneurial activities. In particular, an interest is shown in how cohesion and diversity may affect entrepreneurial outcomes like survival, profitability, innovation and efficiency.
Design/methodology/approach
The paper organizes the literature and presents conclusions about the effects of cohesion and diversity using three stages of entrepreneurial activity: opportunity development, technology and organizational creation, and exchange.
Findings
At the opportunity stage, strong ties with entrepreneurs increase the likelihood of becoming one, but are associated with lower levels of innovation. Diverse ties increase self‐efficacy and innovation. At the technology and organizational creation stage, most entrepreneurial teams are homogeneous whereas team diversity is associated with better organizational outcomes. Using strong ties to recruit potential employees provides price and commitment advantages, but may interfere with efficiency. At the exchange stage, entrepreneurs must strike a balance between weak (market based) and stronger (embedded) ties to gain preferential access to resources and customers, while maintaining diverse sources for information and market opportunities. Overall, cohesion through strong ties provides entrepreneurs with hard to find resources very early in the development of new ventures, but those resources are limited in scope and have a high cost. By contrast, diversity is more common and more important later in a venture's life cycle.
Originality/value
Guidelines are suggested regarding the best networking strategies at the different stages and in different instrumental areas, offering an overall evaluation of the evidence in the cohesion v. diversity debate. Directions for future research on the effects of networks on entrepreneurial outcomes are also provided.

Abstract
Location, insulation, stress‐relieving, regardless of the materials of construction, contribute much in extending the life of storage tanks. This article discusses factors which either promote the occurrence of local anodes and cathodes or cause abnormal corrosive conditions and shows how they can be minimised by proper design.

Abstract
Purpose
The purpose of this paper is to evaluate the protection against corrosion of carbon steel SAE 1020 promoted by a niobium- and titanium-based coating produced from a resin obtained by the Pechini method.
Design/methodology/approach
A resin was prepared with ammonium niobium oxalate as niobium precursor and K2TiF6 as titanium precursor. Carbon Steel SAE 1020 plates were dip coated in the resin and calcinated for 1 h at 600 ºC. Scanning electron microscopy, energy dispersive spectroscopy and X-ray diffraction were used to characterize the coating morphologically and structurally. Open circuit potential, electrochemical impedance spectroscopy, anodic potentiodynamic polarization and scanning vibrating electrode technique were used to evaluate the corrosion protection of the coating.
Findings
The electrochemical analyses evidence slight protection against corrosion of the coating by itself; however, the needle-like crystal structure obtained may potentially provide a good anchorage site, suggesting the coating could be used as a pretreatment that may present similar application to phosphating processes, generating lower environmental impacts.
Originality/value
Due to increasingly restrictive environmental laws, new environmentally friendlier surface treatments must be researched. This paper approaches this matter using a combination of niobium- and titanium-based coating, produced by a cleaner process, the Pechini method.

This paper aims to explore drivers of entrepreneurial intentions of working mothers.
Abstract
Purpose
This paper aims to explore drivers of entrepreneurial intentions of working mothers.
Design/methodology/approach
This paper is a survey-based method using sample of 397 working mothers in India.
Findings
Mothers’ entrepreneurial intention is negatively associated with firms’ perceived family support policies and positively associated with perceived family support. Gains from organization and family support were further enhanced for working mothers’ entrepreneurial intention through the moderating effect of perceived entrepreneurial self-efficacy.
Originality/value
Drivers of entrepreneurship intentions of mothers is scantly explored in past literature. Understanding working mothers’ entrepreneurial intentions could help firms and families provide appropriate environments and opportunities for mothers’ growth.

Abstract
Purpose
Economic integration of refugees remains a challenge for developed countries. Although refugees differ greatly from labor migrants in available resources and motivation toward self-employment, prevailing studies on minority and ethnic entrepreneurship tend to lump these different categories of migrants together. Based on theories of migrants’ economic embeddedness, the purpose of this paper is to analyze the extent to which family- and kinship-based resources affect self-employment duration among refugees and labor migrants.
Design/methodology/approach
Based on Cox regression models, this longitudinal study estimates the self-employment duration of 10,519 refugees and 2,503 labor migrants starting businesses in Sweden in the period 2006–2012.
Findings
Results reveal that while refugees are at a disadvantage to labor migrants in terms of self-employment duration, their higher level of family embeddedness in part helps them overcome these disadvantages. For refugees but not for labor migrants, co-location in an ethnic enclave also lowers the risk of them becoming unemployed after a spell in entrepreneurship.
Originality/value
This original paper provides empirical and theoretical contributions to research on migrants’ self-employment success. It also discusses contributions for research on entrepreneurs’ social embeddedness and refugees’ entrepreneurship.

Abstract
Purpose
Based on the collective agentic perspective of social cognitive theory and supplemented by social support theory, this study aims to investigate how the entrepreneurial collective efficacy of entrepreneurial teams impacts team effectiveness. Specifically, this study hypothesizes that entrepreneurial collective efficacy is a critical factor affecting effectiveness through the mechanism of instrumental support to varying extents, depending on team size.
Design/methodology/approach
The hypotheses were tested on a Chinese sample of new venture teams (N teams = 81; N individuals = 335). A multisource questionnaire that included questions for team leaders and other team decision makers was designed. The data on entrepreneurial collective efficacy (six items) and instrumental support (four items) comprised the aggregate responses from all team members; the data on team effectiveness (seven items) was reported by team leaders.
Findings
The findings indicate that entrepreneurial collective efficacy is positively associated with team effectiveness through instrumental support, especially in small teams.
Originality/value
This study makes important contributions to the research related to exploring in uncertain environments (entrepreneurship) how (instrumental support) entrepreneurial collective efficacy impacts team effectiveness, as well as more particularly under what conditions (team size), all within the specific context of collectivistic cultures (China).

Abstract
Purpose
The purpose of this paper is to identify corrosion types and corrosion transitions by a novel electrochemical noise analysis method based on Adaboost.
Design/methodology/approach
The corrosion behavior of Q235 steel was investigated in typical passivation, uniform corrosion and pitting solution by electrochemical noise. Nine feature parameters were extracted from the electrochemical noise data based on statistical analysis and shot noise theory. The feature parameters were analysis by Adaboost to train model and identify corrosion types. The trained Adaboost model was used to identify corrosion type transitions.
Findings
Adaboost algorithm can accurately identify the corrosion type, and the accuracy rate is 99.25%. The identification results of Adaboost for the corrosion type are consistent with corroded morphology analysis. Compared with other machine learning, Adaboost can identify corrosion types more accurately. For corrosion type transition, Adaboost can effectively identify the transition from passivation to uniform corrosion and from passivation to pitting corrosion consistent with corroded morphology analysis.
Originality/value
Adaboost is a suitable method for prediction of corrosion type and transitions. Adaboost can establish the classification model of metal corrosion, which can more conveniently and accurately explore the corrosion types. Adaboost provides important reference for corrosion prediction and protection.

Abstract
Purpose
Recent research acknowledges entrepreneurial passion’s outcomes, but far less is known about how entrepreneurial passion comes about. In this study, the authors are interested in the emergence of entrepreneurial passion, and how competences and social network are associated with entrepreneurial passion. The paper aims to discuss these issues.
Design/methodology/approach
The authors investigate whether entrepreneurial passion emerges out of socialisation, entrepreneurial experience or various combinations thereof. The authors tested the hypotheses on a data set of entrepreneurs who started their businesses with government financial support (n=1150).
Findings
The findings show that within a social environment, perceived emotional support is positively associated with entrepreneurial passion. Moreover, entrepreneurs’ task-related competence moderates this relationship positively. By investigating the emergence of entrepreneurial passion, the authors contribute to prior passion literature, which has mainly focused on its consequences.
Originality/value
The findings demonstrate both how entrepreneurial passion is associated with and how perceived emotional support can stem from unexpected sources, such as from a government-based start-up grant. For entrepreneurs, an increased awareness of passion’s emergence could better encourage them in their entrepreneurial endeavours. To people who are engaged in promoting entrepreneurship, our findings emphasise the symbolic and emotional aspects of instruments intended to support entrepreneurship.
