Abstract
The present study focusses on algorithmic aspects related to deformation dependent loads in non‐linear static finite element analysis. If the deformation dependency is considered only on the right hand side, a considerable increase in the number of iterations follows. It may also cause failure of convergence in the proximity of critical points. If in turn the deformation dependent loading is included within the consistent linearization, an additional left hand side term emerges, the so‐called load stiffness matrix. In this paper several numerical test cases are used to show and quantify the influence of the two different approaches on the iteration process. Consideration of the complete load stiffness matrix may result in a cumbersome coding effort, different for each load case, and in certain cases its derivation is even not practicable at all. Therefore also several formulations for approximated load stiffness matrices are presented. It is shown that these simplifications not only reduce the additional effort for linearization and implementation, but also keep the iterative costs relatively small and still allow the calculation of the entire equilibrium path.

Abstract
Purpose
Adaptive load-bearing structures pursue the approach of saving mass within a load-bearing structure by adding external energy, thus saving materials and resources. This paper provides an overview of current research developments and shows some examples of existing prototypes.
Design/methodology/approach
First, basic terms and definitions from the research field of adaptive structures are introduced. After a brief historical insight, the numerical methods and prototypes used are presented as examples. The paper concludes with a summary of the state-of-the-art and open questions.
Findings
The current state of the art shows that the idea of adaptive structures offers great potential for more sustainability and resource efficiency in the construction industry. However, it also shows that research is still at the basic stage and that there are still some gaps in research.
Originality/value
The implementation of adaptive load-bearing structures is just one of many different approaches to greater sustainability in the construction sector. The issue of adaptive structures is a highly interdisciplinary field of research. The following paper is a literature review intended to summarize and critically evaluate the state-of-the-art research in this field. In the final section, some open questions are addressed, indicating that this research topic is still evolving.

Abstract
Purpose
The combination of action and process has remained the attention of the psychology of entrepreneurship research. Moreover, special attention has also been paid to the whens and hows of entrepreneurial psychological training. Keeping this in view the current study has tested the impact of individual entrepreneurial orientation (IEO) training on small business entrepreneurial career resilience. Using action regulation theory (ART), a serial mediation model of IEO behaviour and entrepreneurial career adaptability is hypothesised.
Design/methodology/approach
This study used a longitudinal randomised controlled field experiment in which the data were collected at four points. A total of 546 small business owners from Lahore, Pakistan, participated in this research (training group = 265, control group = 281). The data were analysed using ANCOVAs and PROCESS Model 6.
Findings
The research has found that IEO training impacts the entrepreneurial career resilience of small business owners through the development of IEO behaviour and career adaptability.
Originality/value
This experimental inquiry is a novel attempt to extend the career-related outcomes of IEO training (career resilience) based on ART through the mediating role of IEO behaviour and career adaptability. In addition, it has tested the IEO training in the developing country of Pakistan, which is a relevant context for enhancing its socio-economic growth.

Abstract
Purpose
To increase the understanding of how entrepreneurship education impacts entrepreneurial careers, the purpose of the paper is to investigate the role that a venture creation program (VCP) might have in mitigating or surpassing a lack of other antecedents of entrepreneurial careers. In particular, the authors focus on entrepreneurial pedigree and prior entrepreneurial experience.
Design/methodology/approach
Data from graduates of VCPs at three universities in Northern Europe were collected through an online survey. Questions addressed graduate background prior to education, yearly occupational employment subsequent to graduation and graduates' own perceptions of entrepreneurial activity in employment positions. The survey was sent to 1,326 graduates and received 692 responses (52.2% response rate).
Findings
The type of VCP, either independent (Ind-VCP) or corporate venture creation (Corp-VCP), influenced the mitigation of prior entrepreneurial experience. Prior entrepreneurial experience, together with Ind-VCP, made a career as self-employed more likely. However, this was not the case for Corp-VCP in subsequently choosing intrapreneurial careers. Entrepreneurial pedigree had no significant effect on career choice other than for hybrid careers.
Research limitations/implications
Entrepreneurial experience gained from VCPs seems to influence graduates toward future entrepreneurial careers. Evidence supports the conclusion that many VCP graduates who lack prior entrepreneurial experience or entrepreneurial pedigree can develop sufficient entrepreneurial competencies through the program.
Originality/value
This study offers novel evidence that entrepreneurship education can compensate for a lack of prior entrepreneurial experience and exposure for students preparing for entrepreneurial careers.

Abstract
Purpose
This paper aimed to evaluate the differences in the use and knowledge of export promotion programs (EPPs) between Brazilian SMEs that internationalized early and SMEs that internationalized in a gradual, traditional fashion. Additionally, it tested hypotheses that distinguish these two types of SME internationalization processes in an emerging market context.
Design/methodology/approach
The authors tested four hypotheses in a sample of 540 SME Brazilian exporters. The sample was divided into two groups according to the born global (BG) criteria: 379 SMEs with gradual or traditional internationalization (TI) and 161 SMEs with early internationalization (EI).
Findings
The results indicate that Brazilian EI SMEs operate in more countries and continents than TI SMEs. In emerging countries such as Brazil, the domestic market continues to play an important role both for SMEs that internationalize early and those whose process is slower. Even though logistic regression could not classify the sample of TI and EI SMEs according to their knowledge about EPPs, the results led to the idea that EI SMEs currently use more specific EPPs than do TI SMEs.
Practical implications
Managers of successful SMEs from emerging markets need to incorporate EPPs into their internationalization strategy. In emerging markets with large domestic markets, SME managers can meet their growth needs by exploiting opportunities in both domestic and international markets.
Originality/value
Research on the early internationalization of SMEs has long focused on SMEs from developed markets and on internal factors. Moreover, the effects of EPPs on the firm' performance of large and SME firms has also been the subject of study. The value of this paper relies on the intersection of EPPs and the early internationalization of SMEs, even for firms in developed markets.

Abstract
Research indicates that faculty of color in the United States face numerous challenges in the academy. To complicate their experiences further, children significantly impact academics’ work. Additional difficulties can arise in balancing work with familial responsibilities. Indeed, strategies to navigate parental obligations while engaging in professional activities are seldom examined among minority parents, across genders and institution types. In response, the current study investigates the intersectionality of race, gender, and parenthood on navigating a work–life balance in academia. This study examines 13 male and female minority parents from an array of institutions and explores their strategies for navigating professional advancement while managing familial obligations.
Our data suggest that parents of color often develop timesaving strategies to complete their work more efficiently. However, in order to do so, they tend to engage in professional and social isolation and to recalibrate personal expectations of work and accomplishments. Of importance, the study uncovered significant gender differences. While fathers faced comparable challenges, the findings indicate that familial responsibilities can disadvantage women more so by impacting their ability to foster professional relationships and potentially harm their emotional well-being. While most faculty of color face difficulties in the workplace, we argue that those with children, especially mothers, face additional challenges that should be addressed by home institutions to foster more equitable opportunities for professional growth.

Abstract
Purpose
Entrepreneurship can help tackle economic problems, such as unemployment. It is often promoted through education programs. There is a limited comprehensive and rigorous understanding of how entrepreneurship education programs and their ubiquitous distance delivery affect young people's entrepreneurial self-efficacy and intention, particularly in non-formal settings. The purpose of this study is to address this gap.
Design/methodology/approach
Underpinned by the Social Cognitive Theory, this paper investigates the effects of one entrepreneurship education program in a study with 145 young people from five countries aged 18 to 25 years, 62 Intervention and 83 Control participants. The program's impact on the participants' entrepreneurial intention and self-efficacy (across six sub-dimensions) was assessed in a one-off two-week quasi-experiment. Ex-ante and ex-post self-reported data were collected about the participants.
Findings
One-way analyses of covariance were performed to assess separately for changes in the Intervention participants' answers, relative to the Control group. The results of this study suggest the program significantly affected all measures.
Originality/value
These findings contribute to the discussions on the education programs’ effectiveness in promoting entrepreneurship. As a result, they may contribute to entrepreneurship education overcoming geographical and socio-economic hurdles (cost, time and entry barriers) to advance the development of industry, economy and community worldwide.

Abstract
Purpose
Although there are more primarily undergraduate institutions (PUIs) than research-oriented institutions (ROIs) in the United States and more professors work at PUIs than ROIs, most research on gender inequality among faculty has focused on ROIs. Do patterns of women’s numeric scarcity, gender-hostile work climates, and difficulties with work-life balance found at ROIs hold true for PUIs? This chapter examines one PUI to address this question.
Methods
We analyze data from four sources: an archival database of all professors at the institution, interviews with full and associate professors, and two surveys.
Findings
Similar to ROIs, our study found women were less likely to achieve higher ranks, and take longer than men to do so. However, we find greater numbers of women and few gender differences in perception of climate, so numeric scarcity and gender-hostile climate cannot explain persistent lags in women’s advancement. Instead, we find women struggle with work-life balance more than men, especially in science disciplines. Thus, gender parity in advancement has yet to fully emerge, despite more women in the faculty and a more equitable climate than at ROIs.
Research implications
Differences between faculty cohorts are intensified at the PUI because of changes to the institution’s mission, but our research demonstrates that not all gendered patterns found at ROIs apply to PUIs.
Practical and social implications
PUIs that increasingly emphasize scholarly output should enact family-friendly policies to support all professors, including on-campus or subsidized childcare, flexible scheduling, family leave, and dual-career hiring policies.
Originality/value
This chapter demonstrates that there are important differences between ROIs and PUIs that must be taken into account if we are to understand and remedy gender inequality in academia.
