Previous studies on special dielectrics for multilayer screen printing led to defining a new concept for standard alumina substrate. The modification of the process and structure permits an increase of the thermal conductivity. The thermal conductivity of this new material is between that of alumina and BeO. It is possible to increase the thermal conductivity of 94% standard alumina (used in chip‐carriers) up to 3·6 times. It it known that the thermal conductivity of beryllia is 7 times higher than that of alumina. The thermal model gives an increase of 4 times for other configurations non‐tested in this study. With this material, the other characteristics such as thermal expansion, adhesion of the conductors, etc., scarcely change. The ‘percolation’ effect of the physical properties can usually be found with the addition of another material inside the matrix. In this particular case, the material is not submitted to the percolation law. Different configurations of metallic insert alumina with beryllia are compared by a simulation programme. The main applications are in the field of electronic packaging such as chip‐carriers with higher thermal dissipation and substrates for power devices. Since the process used to produce this new material is based on standard operations well known by alumina manufacturers, the cost is potentially much lower than for BeO.

This chapter explores the provision of library services to children residing in juvenile justice facilities. The small body of scholarly literature published on the topic over the last 50 years is examined, followed by a description of the findings of a recent Australian survey of juvenile justice library provision in that country. Australia presents a very poor example of the provision of library services to children living in correctional detention. A contrast to the Australian context is provided through a case study of the library service to the South Carolina Birchwood School, in the United States. Housed in the South Carolina Juvenile Justice Centre, the Birchwood School library is presented as an example of better practice and an illustration of what can be achieved by a juvenile justice facility library when it is sufficiently staffed and funded. Opportunities for further research are identified and conclusions are drawn regarding the need for libraries in juvenile justice facilities.

This study aims to determine the impact of personality traits and social experience on Indonesian youngsters’ intention to purchase impulsively from social commerce (SC) platforms. Furthermore, latent state-trait, personal traits and social impact were used to determine the factors influencing this impulsive behavior.

This is a theoretical research model with data obtained from 658 Indonesian youngsters between the ages of 18 and 24. The data were prepared using exploratory and confirmatory factors with the structural equation modeling (SEM) approach used to analyze the direct, indirect and moderating effects.

The result showed that hedonic motivation is the most influential personality trait construct that directly determines youngsters’ purchasing intention, followed by perceived behavior control. Furthermore, their constructs from social experience, namely, subjective norms and peer communication, significantly have an indirect effect on the dependent variable through mediator hedonic motivation and perceived behavior control.

Preliminary studies neglected the social interaction process used by youngsters’ in the impulsive purchase of the SC context. Therefore, this research postulated the associated factors by involving their interplay between personal traits and social experience.

A “sentence,” according to the Oxford English Dictionary, is a pronouncement of opinion, a pithy statement, an authoritative decision, or an idea expressed in a grammatically complete, self-contained utterance. Notice that these definitions all emphasize thought rather than action. Of course, sentences – such as “Let there be light,” “Keep off the grass,” “You shall be hanged by the neck until dead,” and “Notice that these definitions all emphasize thought rather than action” – may command or recommend an act. Some philosophers even maintain that “certain classes of utterances, in certain situations…bring about, rather than refer to, a new state of fact” (Hollander, 1996, p. 178). J. L. Austin, whose book How to Do Things with Words established the field of speech-act theory, argues that “performative” statements can have the effect of actions (1962).¹ And yet the words in a sentence – whether it is an ordinary linguistic unit or the judgment in a criminal case – are still distinguishable from the deed they describe. The differences between pronouncing and executing sentences even led Justice Antonin Scalia to assert, in Wilson v. Seiter, that restrictions against “cruel and unusual punishment” should apply only to pain “formally meted out as punishment by the statute or the sentencing judge,” or meant to be cruel and unusual by the inflicting officer (1991, p. 2325). He is assuming, of course, a legal system that “guarantees – or is supposed to – a relatively faithful adherence to the word of the judge in the deeds carried out against the prisoner” (Cover, 1992, p. 225).² As Scalia’s remarks demonstrate, however, the distinction between a sentence’s pronouncement, on the one hand, and its execution, on the other, raises disturbing questions about intention, interpretation, agency, and responsibility.

Little attention has been given specifically to the experience of women social entrepreneurs despite the assumption they are prone to “care”, and even less to their motivations or their self-perception of success. This paper aims to provide an insight into the relationship between motivations and social and economic performance among women social entrepreneurs in ten European Union countries.

This paper classifies the motivations of women social entrepreneurs, drawing on the results of a survey conducted (n = 380) by the European Women’s Lobby. The paper then examines how these motivations relate to self-perceptions of social and economic performance.

In addition to being driven by self-interest and prosocial motivations, women social entrepreneurs also seek to develop alternative business models. Where a social mission is central, women are likely to feel successful in meeting their social aim; however, there is a strong negative relationship between self-interested motivations and revenue.

This analysis relies on perceptual and self-reported data; therefore, more objective measures should be considered for further research, possibly combined with a longitudinal design. Another limitation of this paper lies in the non-random sampling strategy used to identify a hard-to-reach population such as women social entrepreneurs.

The findings provide a better understanding of the motivations of women social entrepreneurs. This may be useful in assisting funding or support organisations, as well as social investors, evaluate where to best invest resources. In addition, a more nuanced understanding of motivations among women social entrepreneurs can inform policies aimed at supporting women social entrepreneurs, without necessarily being bound by the expectation to maximise economic and/or social outcomes.

This paper demonstrates the centrality of the social mission for women social entrepreneurs. The results also identify “seeking an alternative business model” as a key motivation among women social entrepreneurs, thereby breaking existing conceptualisations of entrepreneurial motivations on a binary spectrum as either “self-interested” or “prosocial”. The paper also shows that having other than prosocial motivations for becoming a social entrepreneur does not necessarily lead to higher economic revenue.

RETROSPECT is natural at the beginning of a new library year. All over the world of libraries of all kinds the shadow of the general depression has fallen; more heavily perhaps in the United States than here. It is a testing time which has made the enemies of libraries vocal and has also fortunately roused their advocates. On balance, optimism may prevail; and in that faith we wish our readers a happy new year.

Whether or not women have children has profound consequences for their employment experiences. Employers may see women with no children as conforming more closely than women with children (and yet not as closely as male employees) to the pervasive ‘ideal worker’ stereotype of a full-time, committed worker with no external responsibilities. However, managers and co-workers may also perceive women with no children as deviating from prevailing pronatalist norms in Australian and other comparable societies, which construct and value women as mothers and stigmatise and devalue women with no children. Accordingly, women with no children may be rewarded or penalised in different employment contexts at different times according to the degree to which they conform to or deviate from the most salient characteristics associated with the ideal worker and mothering femininity. This chapter explores patriarchal and capitalist configurations of femininities, masculinities and workers as drivers of employment experiences among women with no children. It then discusses empirical research from Australia and comparable countries, in order to elucidate the diversity of employment experiences among women with no children.

The purpose of this paper is to establish the extent to which prospective students can see a visible commitment to study gender in the UK business/management school curriculum prior to enrolment.

A content analysis of the descriptions of modules offered as part of business and management degrees offered by 112 UK universities was conducted. The analysis was restricted to the publicly available information on the websites visible to prospective students. Descriptive statistics regarding the distribution of gender topics across programmes and higher education institutions are presented in addition to university group affiliation (e.g. Russell Group) and accreditation in respect of variables.

The analysis reveals significant gaps in the undergraduate and taught postgraduate offerings of UK business schools that the authors suggest are reflective of subject silos, and institutional risk reduction strategies.

The authors conclude by arguing that accreditation bodies can use their influence to leverage change and to ensure gender content becomes core to curriculum design and its visibility as part of the practice of management to prospective students.

This study provides a benchmark for the visibility of gender as an issue and perspective within UK business/management school offerings.

Within developing countries, particularly in Africa, there is an emerging literature which highlights the unique obstacles faced by women entrepreneurs who start and develop their own businesses (De Vita, Mari, & Poggesi, 2014; Jamali, 2009; Minniti & Naude, 2010; Naude & Havenga, 2005; Nziku & Struthers, 2018). A key objective of this chapter is to critically appraise some of the conceptual approaches adopted in this literature. In so doing, the authors revisit a seminal paper first developed by Granovetter (1973) which suggested that female entrepreneurs, instead of being disadvantaged by the so-called ‘weak ties’ that bind their business networks, actually enjoy compensating benefits which Granovetter referred to as the strength of weak ties (SWT). Building on the conceptual work of Nziku and Struthers (2018) which developed an innovative taxonomy for analysing the SWT concept within a Principal-Agent (P-A) paradigm, the chapter will set out new insights which challenge some of the assumptions of the extant entrepreneurship literature. In particular, that women are inherently more risk averse in their business decision making than men. The theoretical context for this will be derived from a behavioural economics methodology first developed by Kahneman and Tversky (1979). They introduced the concept of loss aversion as a more realistic approach to attitudes towards risk on the part of entrepreneurs than risk aversion. The chapter contends that the loss aversion perspective may be more appropriate to the decision-making frame adopted by female entrepreneurs, especially in the context of Africa as well as in other developing regions of the world. The chapter will therefore suggest that such an approach can yield fresh insights on the topic of female entrepreneurship which the extant literature heretofore has not addressed, though this will have to be subsequently tested empirically.

The purpose of this paper is to provide an improved genetic algorithm to solve 0/1 multidimensional knapsack problem (0/1 MKP), by proposing new selection and crossover operators that cooperate to explore the search space.

The authors first present a new sexual selection strategy that significantly improves the one proposed by (Varnamkhasti and Lee, 2012), while working in phenotype space. Then they propose two variants of the two-stage recombination operator of (Aghezzaf and Naimi, 2009), while they adapt the latter in the context of 0/1 MKP. The authors evaluate the efficiency of both proposed operators on a large set of 0/1 MKP benchmark instances. The obtained results are compared against that of conventional selection and crossover operators, in terms of solution quality and computing time.

The paper shows that the proposed selection respects the two major factors of any metaheuristic: exploration and exploitation aspects. Furthermore, the first variant of the two-stage recombination operator pushes the search space towards exploitation, while the second variant increases the genetic diversity. The paper then demonstrates that the improved genetic algorithm combining the two proposed operators is a competitive method for solving the 0/1 MKP.

Although only 0/1 MKP standard instances were tested in the empirical experiments in this paper, the improved genetic algorithm can be used as a powerful tool to solve many real-world applications of 0/1 MKP, as the latter models several industrial and investment issues. Moreover, the proposed selection and crossover operators can be incorporated into other bio-inspired algorithms to improve their performance. Furthermore, the two proposed operators can be adapted to solve other binary combinatorial optimization problems.

This research study provides an effective solution for a well-known non-deterministic polynomial-time (NP)-hard combinatorial optimization problem; that is 0/1 MKP, by tackling it with an improved genetic algorithm. The proposed evolutionary mechanism is based on two new genetic operators. The first proposed operator is a new and deeply different variant of the so-called sexual selection that has been rarely addressed in the literature. The second proposed operator is an adaptation of the two-stage recombination operator in the 0/1 MKP context. This adaptation results in two variants of the two-stage recombination operator that aim to improve the quality of encountered solutions, while taking advantage of the sexual selection criteria to prevent the classical issue of genetic algorithm that is premature convergence.
