Abstract

Coupled problems are of great interest in the area of technical applications. In the current paper we present the theory of thermo‐electro‐mechanical coupling and provide a discretization by using the method of finite elements. The thermo‐electro‐mechanical effect presents a physical interaction between the fundamental quantities of the sub‐domains elastomechanics, electrostatics and heat balance. Throughout thermodynamic analysis we derive the constitutive equations which describe the above behaviour and relate the main quantities which describe the three fields. From the principal equations of elastomechanics, electrostatics and heat balance separately, we derive the weak formulation of the load equilibrium, the electrostatic equilibrium and the heat balance individually. Furthermore a FE‐formulation leads the weak formulations of the coupled problem to a system of three coupling differential equations. This system is non‐linear with respect to the temperature and we solve it using an incremental solution. The numerical result is to be shown on a one‐dimensional test example.

Abstract

The purpose of this chapter is to conduct a structured literature review to examine the relationship between entrepreneurship and emotional intelligence in academic settings as well as the current entrepreneurship pedagogy for flexible, innovative and creative graduates. One hundred and twenty-eight peer-reviewed papers were analysed based on Webster’s and Watson’s (2002) methodology. Papers classified into three topics and a content analysis was implemented to discuss about the publication year, journals, authors, frequency of keywords and research method adopted. The contribution of this chapter is twofold. It is a bibliometric study which provides a macropicture of a research field, its evolution and connections among studies, in order to be a starting point for future researchers who are already studying entrepreneurial education or entrepreneurship-related scientific areas. Also, this chapter helps academics to improve educational programmes and curriculum to increase students’ entrepreneurial intention taking into account the factors that affect it.

Abstract

Purpose

The purpose of this study is to explore the difference in entrepreneurial intentions, perceived entrepreneurial motivation, and cognitive profiles (attitudes towards entrepreneurship, perceived behaviour control, and subjective norms) between individuals who have participated in enterprise education programmes in the universities and those who have not. The paper also investigates the mediating role of attitudes towards entrepreneurship, perceived behaviour control, and subjective norms related to entrepreneurial motivation and the forming of entrepreneurial intentions.

Design/methodology/approach

Survey information from 321 students from three universities in the Ukraine was hand collected. Hierarchical multiple regressions were used to test hypotheses.

Findings

Individuals who participate in enterprise programmes tend to have higher entrepreneurial motivation and are more likely to become entrepreneurs. Empirical evidence shows that attitudes, subjective norms and perceived behaviour control mediate the relationship between perceived entrepreneurial motivation and entrepreneurial intentions.

Research limitations/implications

The study is based on data collected from three universities in one city. The implications for education managers related to the inclusion of enterprise courses into the study plans of engineering students are also discussed here.

Practical implications

The findings have implications for the stimulation of student enterprise in transitional economies where attitudinal and resource (i.e. skill, competence and knowledge) deficiencies can retard enterprise. Entrepreneurial motivation is an important link between an intention and action. Enterprise education programs which stimulate entrepreneurial motivation should be offered to engineering students since many of them start ventures later. Engagement into enterprise development programs of engineering students might evoke earlier interest in self‐employment career path among young people.

Originality/value

The article contributes to the field of entrepreneurial motivation and intentions. The study extends insights from the theory of planned behaviour (TPB) (i.e. subjective norms, attitudes toward this behaviour, and perceived behavioural control) by also considering the perceived entrepreneurial motivation profiles of students.

Abstract

Our paper discusses the need for continued focus on ethical leadership and the importance and benefits of ethical leadership development. We propose integrating ethical leadership development, that uses cognitive development theory, into the Center for Creative Leadership’s Assess, Challenge, and Support (ACS) leader development model to help address the continued failures of ethical leader development. Our extended framework includes values and morals as a component of the model, and ethical organizational culture as its backdrop, thereby incorporating an examination of ethical leadership into each component of the ACS model. We conclude with practical implications and suggestions for future research.

Abstract

Purpose

The purpose of this study is to develop a simulation method to calculate non-stationary distributions of the chemical potential of oxygen in a solid oxide fuel cell (SOFC) under operation.

Design/methodology/approach

The initial-boundary value problem was appropriately formulated and the appropriate boundary conditions were implemented so that the problem of non-stationary behavior of SOFC can be solved in accordance with actual operational and typical experimental conditions. The dependencies of the material properties on the temperature and partial pressure of oxygen were also elaborately introduced to realize actual material responses. The capability of the proposed simulation method was demonstrated under arbitrary operating conditions.

Findings

The steady state calculated with the open circuit voltage condition was conformable with the analytical solution. In addition, the transient states of the spatial distributions of potentials and currents under the voltage- and current-controlled conditions were successfully differentiated, even though they eventually became the same steady state. Furthermore, the effects of dense materials assumed for interconnects and current collectors were found to not be influential. It is thus safe to conclude that the proposed method enables us to simulate any type of transient simulations regardless of controlling conditions.

Practical implications

Although only uniaxial models were tested in the numerical examples in this paper, the proposed method is applicable for arbitrary shapes of SOFC cells.

Originality/value

The value of this paper is that adequate numerical simulations by the proposed method properly captured the electrochemical transient transport phenomena in SOFC under various operational conditions, and that the applicability was confirmed by some numerical examples.

Abstract

The present chapter addresses a topic that is of growing interest – namely, the exploration of alternative item response theory (IRT) models for noncognitive assessment. Previous research in the assessment of trait emotional intelligence (or “trait emotional self-efficacy”) has been limited to traditional psychometric techniques (e.g., classical test theory) under the notion of a dominance response processes describing the relationship between individuals' latent characteristics and individuals' response selection. The present study, presents the first unfolding IRT modeling effort in the general field of emotional intelligence (EI). We applied the Generalized Graded Unfolding Model (GGUM) in order to evaluate the response process and the item properties on the short form of the trait emotional intelligence questionnaire (TEIQue-SF). A sample of 866 participants completed the English version of the TEIQue-SF. Results suggests that the GGUM has an adequate fit to the data. Furthermore, inspection of the test information and standard error functions revealed that the TEIQue-SF is accurate for low and middle scores on the construct; however several items had low discrimination parameters. Implications for the benefits of unfolding models in the assessment of trait EI are discussed.

Abstract

Purpose

The purpose of this article is to recognize emotional intelligence (EI) as a specific emotional competency possessed by entrepreneurs that facilitates their coping with stressors that arise in their day-to-day work. Highlighting the problem-focused and emotion-focused coping strategies employed by entrepreneurs, the paper establishes that EI in entrepreneurs enables the onset of acceptance of the existence of a stressful situation and that of optimism that a stressful situation can be solved.

Design/methodology/approach

The paper reviews literature on the topics related to links between EI, entrepreneurial behaviors and entrepreneurial coping. Subsequently, acceptance-avoidance motivation theory is used to posit that entrepreneurs' EI serves as an antecedent that (1) guides the selection of their coping strategies through onset of optimism and acceptance of stressful situation, (2) assists in perceiving those situations as either controllable or uncontrollable and (3) shapes the actual process through which entrepreneurs cope.

Findings

The proposed conceptual model asserts that entrepreneurs' EI as reflected in their abilities to perceive, use, understand and regulate emotions is key to their coping. EI in entrepreneurs assists them in being optimistic about solving a stressful situation and accepting of such situations as well. Thereafter, selection of a problem-focused or emotion-focused coping strategy or both ensues.

Originality/value

The current work offers a conceptual model that highlights the role of entrepreneurs' EI in coping, integrates both the cognitive and affective components of coping and suggests a variety of avenues for future research. This model extends models of coping that categorize coping types to specify the process thought to be involved. Understanding the role of emotional intelligence in coping with stress by entrepreneurs has theoretical and practical implications which are discussed as well.
