Abstract

Purpose

This paper aims to investigate the thermal characteristics of the clutch hydraulic system under various oil flow conditions. Increasing the oil flow is one of the most important approaches to reduce the clutch temperature. However, the effect of the oil flow on the clutch temperature remains to be explored.

Design/methodology/approach

The thermal resistance network model and the lumped parameter method are used to study the thermal characteristics of the clutch hydraulic system. The predicted temperature variations of the clutch and the oil are compared with experimental data.

Findings

Results demonstrate that the larger the friction power is, the higher the temperatures of the clutch and the oil are. However, the temperature growth rates of the clutch and oil present different trends: the former decreases gradually and the latter increases constantly. Additionally, increasing the oil flow within a certain range gives rise to the decrease of clutch temperature and the increase of oil temperature; nevertheless, their variation trends are gradually weakening. When the oil flow is large enough, it brings a slight effect on the clutch temperature rise.

Originality/value

This paper extends the knowledge into the oil flow supply of the clutch hydraulic system. The conclusions can provide a theoretical guidance for the oil management of the transmission system. Additionally, the thermal resistance network model is also effective and efficient for other hydraulic equipment to predict the temperature variation.

Abstract

Purpose

The purpose of this paper is to study the landing performance of the Mars lander considering uncertain landing conditions under two landing modes.

Design/methodology/approach

A dynamics analysis model for the legged Mars lander is established for landing simulation, where the nonlinear large-deformation flexible buffer rods are equivalently modeled with a rigid-body mechanism with external forces and movement limit. Sensitivities of the landing stability to various landing conditions are analyzed using the Quasi–Monte-Carlo-based Sobol’ method and computer-aided landing simulations. Moreover, based on the results of sensitivity analysis, sensitive parameters are selected for estimating the safe boundaries for stability indices of rotation and clearance.

Findings

It can be concluded from this study that the lander has excellent ability against overturning. The shutdown-before-touchdown strategy helps to maintain than landing pose, and the shutdown-at-touchdown strategy helps to prevent the nozzle from colliding with the surface of Mars.

Practical implications

This study provides a theoretical reference to choose the better landing strategies for Mars landers considering uncertain landing conditions.

Originality/value

A parameterized dynamics Mars lander model and a simplification method are proposed to simulate the landing on Mars. Uncertain landing conditions are parameterized and considered in the dynamics model. Sensitivity analysis and safe boundary methods are used to compare the landing performances with two landing strategies.

Abstract

Drawing on Bourdieu's field, habitus, and capital, I show how disparate experiences and “dispositions” shaped several departments’ development in the organization behind the annual Burning Man event. Observations and interviews with organizers and members indicated that in departments with hierarchical professional norms or total institution-like conditions, members privileged their capital over others’ capital to enhance their authority and departmental solidarity. For another department, the availability of multiple practices in their field fostered disagreement, forcing members to articulate stances. These comparisons uncover conditions that exacerbate conflicts over authority and show how members use different types of capital to augment their authority.

Abstract

Women perform the majority of household labour in many families around the world. However, the unequal division of household labour does not lead to dissatisfaction among women. In the present study, the author introduced the intergenerational household assistance to understand married women’s and men’s satisfaction with division of household labour in China, in addition to three major theoretical perspectives in studies of western families (i.e., relative resources, time availability, and gender role ideology). Logistic regression analyses on a nationally representative dataset (the Second Wave Survey of Chinese Women’s Social Status) were performed to study this topic. Consistent with studies in the West, the results show that relative resources, time availability, and gender ideology were associated with married Chinese women’s satisfaction, while married Chinese men’s satisfaction was only associated with time availability (the household labour done by them and their wives). Importantly, married women with parents-in-law’s household assistance tend to be more satisfied than those with help from their parents. The findings demonstrate that Chinese marriages are intertwined with intergenerational relationships and suggest that it is important to take into account of the influence of intergenerational relationships in studies of Chinese marriages.

Abstract

Korean‐American firms are becoming powerful business units, yet some questions arise as to how to manage them in the most effective manner. In order to avoid confusion, a definition of Korean‐American firms is required. Korean‐American firms are Korean firms that have set up operations in the United States in the form of factories, storage facilities, and sales offices. In others words, the companies are owned by Korean business people who are used to the Korean way of doing business, and yet employ many Americans. Korean executives must deal with American workers and managers and understand the corporate structure that is commonly used in the United States. While Korean executives would like to implement their management practices, they need to remember that America employees may respond differently than Korean workers. Consequently, this article will be useful to Koreans investing in the United States, as they will learn about American organisation models. At the same time, this article will be useful to American workers who want to learn about their Korean employers and the business practices and values used in Korea. The main objective of this article is to determine how to maximise the performance of Korean‐American firms.

Abstract

This volume explores an expansive array of organizational imaginaries, or understandings of organizational possibilities, with a focus on how collectivist-democratic organizations offer alternatives to conventional for-profit managerial enterprises. These include worker and consumer cooperatives and other enterprises that, to varying degrees, (1) emphasize social values over profit; (2) are owned not by shareholders but by workers, consumers, or other stakeholders; (3) employ democratic forms of managing their operations; and (4) have social ties to the organization based on moral and emotional commitments. The contributors to this volume examine how these enterprises generate solidarity among members, network with other organizations and communities, contend with market pressures, and enhance their larger organizational ecosystems. In this introductory paper, the authors put forward an inclusive organizational typology whose continuums account for four key sources of variation – values, ownership, management, and social relations – and argue that enterprises fall between these two poles of the collectivist-democratic organization and the for-profit managerial enterprise. Drawing from this volume’s empirical studies, the authors situate these market actors within fields of competition and contestation shaped not just by state action and legal frameworks, but also by the presence or absence of social movements, labor unions, and meta-organizations. This typology challenges conventional conceptualizations of for-profit managerial enterprises as ideals or norms, reconnects past models of organizing among marginalized communities with contemporary and future possibilities, and offers activists and entrepreneurs a sense of the wide range of possibilities for building enterprises that differ from dominant models.

Abstract

Purpose

The number of women choosing entrepreneurship as an occupation continues to grow. However, there are very few start‐up high‐growth ventures in traditionally non‐feminine industries, such as manufacturing or technology. The purpose of this paper is to draw attention to the potential impact of implicit and explicit gender stereotypes on women's high‐growth entrepreneurial intention, and to examine the role of entrepreneurial self‐efficacy in this process. The authors aim to argue that there is a dual stereotype associated with high‐growth entrepreneurship (HGE), which negatively impacts on women's intention and self‐efficacy, thereby limiting their behavior in this arena.

Design/methodology/approach

This is a conceptual paper. Through the lens of stereotype activation theory the authors call for researchers to begin examining these phenomena and to utilize more generalizable samples of entrepreneurial students in future research.

Findings

The paper finds that by decreasing the masculine stereotype‐related barriers associated with HGE and increasing women's HGE self‐efficacy it should be possible to increase women's intention to engage in high‐growth venture creation.

Research limitations/implications

The paper has valuable implications for entrepreneurship educators and trainers.

Practical implications

The paper offers specific and practical suggestions on how entrepreneurship educators and trainers can build women's entrepreneurial self‐efficacy.

Originality/value

In this paper, the authors bring together prior theory and research on entrepreneurship, gender stereotyping and social cognitive theory to provide a research agenda on the relationship between stereotype threat, entrepreneurial self‐efficacy and high‐growth entrepreneurial intention.

Abstract

Purpose

The purpose of this study was to investigate whether the four major factors known to contribute to self-efficacy in general (enactive mastery, vicarious experience, physiological arousal and verbal persuasion) can help account for observed differences in the entrepreneurial self-efficacy (ESE) of young women and men, in particular.

Design/methodology/approach

The authors adopted a two-stage design, which included collecting data from 222 university students via an online survey followed by a quasi-experiment involving an opportunity evaluation task.

Findings

The findings demonstrate that the significantly lower ESE of the young women in the sample was attributable to their lower level of prior entrepreneurial experience, their lower level of positive and negative affect towards entrepreneurship and their higher likelihood of receiving failure feedback due to their actual performance on an opportunity evaluation task.

Research limitations/implications

Given the importance of understanding why females continue to be under-represented in entrepreneurial activity the world over, these findings provide additional insight into why young women tend to feel less efficacious than young men about their ability to successfully undertake an entrepreneurial career.

Originality/value

This paper offers a comprehensive and unified theoretical framework, derived from social learning theory, for furthering the understanding of the factors that contribute to gender differences in ESE. The authors also offer a novel quasi-experimental design involving an opportunity evaluation task that others might find useful, particularly for empirical research adopting a cognitive and/or affective lens on entrepreneurship.

Abstract

Purpose

This paper aims to, drawing on the theory of planned behaviour (TPB), explore the effects of entrepreneurial role models on entrepreneurial intention (EI) and its antecedents and examines the question of whether the effects vary by gender.

Design/methodology/approach

Data were collected from a sample of 331 students at seven universities in Iran. Structural equation modelling and bootstrap procedure were used to analyse the data.

Findings

Consistent with the TPB, our results show entrepreneurial role models to indirectly influence EIs via the antecedents of intention. No gender differences in the relationship between perceived behaviour control and EIs were found, but gender did moderate the other relationships within the TPB. Attitude towards entrepreneurship was a weaker predictor and subjective norms a stronger predictor of EIs for female students than for their male counterparts. Furthermore, perceived behaviour control and attitudes towards entrepreneurship were more strongly influenced by role models for females as opposed to male students.

Research limitations/implications

Future studies should go beyond examining the mere fact of knowing entrepreneurial role models to examine the mechanisms underlying the relationship between role models and EIs.

Practical implications

The results of this study have clear implications for both educators and policymakers.

Originality/value

The study contributes to the entrepreneurship literature by incorporating entrepreneurial role models and gender into the TPB and investigating their mediating and moderating effects within the model.
