Abstract

Empirical rules and experimental evidence are not capable of dealing with both geometric complexity and nonlinearities to design a sufficient accurate, reliable and affordable electrical device. To minimize this gap and to achieve an high performance level in the industry design of an electromagnetic device two CAD packages (electromagnetic CAD package and thermal CAD package) working in parallel processing should be used. In this paper these two packages have been used separately. The finite element technique is used to solve the heat conduction problem in complex devices of arbitrary shape with imposed boundary conditions. As an application example, the steady‐state temperature distribution will be produced for an high voltage cross‐linked polyethylene insulated power cable. The results are discussed and the importance of such a study as an aid to improve the life expectancy of high voltage power cables is pointed out. Finally, several conclusions are suggested to increase the power cable current transmission capacity.

Abstract

Purpose

Interventions to develop leadership have attracted the interest of both the professional world and academia. The latter through review papers has highlighted the need to incorporate organizational performance outcomes when evaluating the effectiveness of programs for leadership development, because they have been particularly scarce. Keeping this in mind, the purpose of this paper is to analyze the effectiveness of an intervention aimed at direct supervisors, on the basis of social skills and transformational/transactional leadership, in order to improve organizational climate (OC) perception and objective outcomes of organizational performance.

Design/methodology/approach

A quasi-experimental pretest-posttest design was used, with no quasi-control group. Intervention was applied to all direct supervisors (n=8) of a private company in the industrial sector, with national implementation. The intervention covered a period of two months, with a total of eight sessions. The frequency of the intervention was a weekly session of 90 minutes each. The impact was measured in their direct subordinates (n=34). The outcome variables were OC perception and various indicators of organizational performance.

Findings

The results showed a statistically significant increase, moderate-to-high magnitude (dMR=0.38-1.21), in most sub-dimensions of OC. The various organizational performance indicators (e.g. volume of sales, positioning of the company, etc.) also showed improvements.

Practical implications

Results suggest that the authors’ intervention program, based on social skills and leadership, aimed to develop leadership, has an effect on organizational efficacy outcomes, such as OC perception and organizational performance. The implications of this study’s findings for HR managers are that there is a direct relation between improvement in outcomes associated with organizational effectiveness and the training of direct supervisors; this is because the leadership in the levels that deal directly with workers is responsible for carrying out the main tasks of the organization.

Originality/value

The overall objective of this research was to analyze the effectiveness of an intervention aimed at direct supervisors, on the basis of social skills and transformational/transactional leadership, in order to improve OC perception and objective outcomes of organizational performance.

Abstract

We present a critical literature review debating Brazilian research on social and environmental accounting (SEA). The aim of this study is to understand the role of politics in the construction of hegemonies in SEA research in Brazil. In particular, we examine the role of hegemony in relation to the co-option of SEA literature and sustainability in the Brazilian context by the logic of development for economic growth in emerging economies. The methodological approach adopts a post-structural perspective that reflects Laclau and Mouffe’s discourse theory. The study employs a hermeneutical, rhetorical approach to understand and classify 352 Brazilian research articles on SEA. We employ Brown and Fraser’s (2006) categorizations of SEA literature to help in our analysis: the business case, the stakeholder–accountability approach, and the critical case. We argue that the business case is prominent in Brazilian studies. Second-stage analysis suggests that the major themes under discussion include measurement, consulting, and descriptive approach. We argue that these themes illustrate the degree of influence of the hegemonic politics relevant to emerging economics, as these themes predominantly concern economic growth and a capitalist context. This paper discusses trends and practices in the Brazilian literature on SEA and argues that the focus means that SEA avoids critical debates of the role of capitalist logics in an emerging economy concerning sustainability. We urge the Brazilian academy to understand the implications of its reifying agenda and engage, counter-hegemonically, in a social and political agenda beyond the hegemonic support of a particular set of capitalist interests.

Abstract

Ideally, a pervasive location‐based system should allow mobile users to go anywhere and benefit from personalized and pro‐active services tailored for their current activity. However, existing location‐based systems are still far from this vision, as they are either aimed at very specific activities or too generic to provide real value to specific user activities. The objective of this work is to identify and characterize the most fundamental challenges involved in the design of pervasive location‐based systems. The approach is based on the idea that such challenges will correspond to the key design tradeoffs for location‐based systems. Building on what is believed to be the high‐level requirements for a truly pervasive locationbased system, this paper proposes a design space with four design dimensions: functional scope, added‐value, pro‐activity, and adaptability. After analyzing a representative set of location‐based systems under that design space, the combinations between functional scope and any of the other dimensions are identified as the main contradictions in the design of such systems. The paper finally discusses the research challenges associated to the identified tradeoffs.

Abstract

Purpose

This chapter contrasts two “careers in dope” (Waldorf, 1973), one a Hispanic crack dealer and the other a White trafficker of powder cocaine. The first dealer worked openly on the street, in the urban style; the latter dealt indoors, exclusively through networks of kin and friends, the only way to sell drugs in the suburbs. This chapter seeks to establish “suburban” drug sales as a particular modality, with dynamics specific to its context.

Methodology/approach

Two in-depth case cases are examined. They are drawn from a larger set of oral interviews that explore the life histories of drug dealers, with an emphasis on how they sold marijuana and cocaine, and how and why they quit selling.

Findings

First, the suburban style of drug sales has much to do with the mitigated risks White people face as dealers. Second, suburban dealing illuminates the limits of conventional economic theory to explain drug dealing universally.

Originality/value

Because suburban drug deals happen among friends and kin relations they are never anonymous. Making sense of economic transactions among intimates raises a number issues fundamental to economic anthropology: the ambivalence of gifts in socialeconomic relationships, and more generally the integration of economic phenomena in social dynamics.

Abstract

Purpose

This study aims to improve the reception and positioning of materials in the warehouse, as well as the internal logistics of a bus manufacturing company by acting upon the processes of supply line management.

Design/methodology/approach

This study is based on the action research methodology which, through a practical approach, intends to generate transferrable knowledge to other organizations whose situations are similar to that of this study. The practical actions and the knowledge acquired co-create the changes needed for the improvement processes.

Findings

Through these improvements, it is possible to standardize supply and eliminate the retention of picking carts on the line, simplify the management of materials provided in supermarket boxes, improve the control of materials and facilitate the process of picking and materials storage. A kanban card-based supply system was also expanded to the bus assembly line, allowing more control over valuable materials.

Originality/value

This study has demonstrated how the implementation of lean techniques on a bus assembly line can lead to increased consistency of supply to the line and improved working conditions, both in the production and warehouse areas. Furthermore, it has set a new standard of the internal logistics processes and the inclusion of process recording in the working instructions.

Abstract

Purpose

This study aims to examine the marketing/R&D relationship under different relative dependence situations. Specifically, its basic objective is to analyse if the effect that the climate between these departments exerts on new product development performance is moderated by the dependence perceived by these areas.

Design/methodology/approach

The interfunctional climate was measured through six key variables of relationship marketing: cooperation, communication, trust, commitment, social satisfaction and conflict. To do this, the R&D directors of 178 Spanish innovative firms were surveyed. A sample of 345 products (177 successes and 168 failures) was been obtained.

Findings

The results derived from a multisample analysis allow the conclusion that in those situations of high dependence the creation of a satisfactory climate is specially important for the development of affective bonds, such as trust and commitment among the functional areas.

Originality/value

The novelty of the research lies in the use of the relationship marketing approach to investigate industrial intra‐functional relationships and their influence on a new product performance. Furthermore, the inclusion of dependence as a possible moderator of that influence represents an added value of the study.

Abstract

Purpose

The purpose of the present study is to analyze the role the existing trust between marketing and R&D plays on a new product development performance. As trust determining factors four key variables of relationship marketing have been considered: satisfaction, cooperation, communication and conflict.

Design/methodology/approach

The R&D directors of 178 Spanish innovative firms were surveyed. A sample of 345 products (177 successes and 168 failures) were obtained. To estimate the model proposed a structural equation analysis was used.

Findings

The success of an innovation is especially favored by the existence of affective bonds among the participants. In this respect, the existing trust between marketing and R&D, directly, and the satisfaction of the areas with the relationship, indirectly through the former, are essential determinants of a new product performance.

Originality/value

The novelty of the research lies in the use of relationship marketing approach to investigate intra‐functional relationships and their influence on a new product performance.

Abstract

Purpose

Students play an unequivocal role in sustainable universities as they are theorized to embody the mission of a sustainable university through a sustainable lifestyle and spread sustainability practices during their professional careers. Despite this, it is not well known how or why students come to embody a sustainable lifestyle. This study aims to better understand the relationship between happiness, academic achievement and sustainability behaviors among the student population in a Mexican higher education institution.

Design/methodology/approach

In a questionnaire study, engineering and psychology university students at a large public university in northwestern Mexico answered questions regarding their environmental sustainability behaviors, happiness and academic performance. A stratified random sampling technique was used to obtain the sample population that best represents the entire population. After chi-square tests, it was confirmed that the three variables were independent of one another. Therefore, a series of correspondence analyses were conducted to examine clusters or patterns that could indicate relationships among the three variables.

Findings

The main finding from this work was that the happiest and most academically astute participants were only slightly environmentally sustainable or not sustainable at all. The lack of environmental sustainability in students from one of the most top-rank sustainable universities in Mexico does not align with previous sustainability reports. External factors to the university, such as cultural values and extreme weather conditions, may have influenced students’ sustainability behaviors.

Research limitations/implications

As with any other questionnaire study, the provided data is subject to interpretation, judgment and bias. In addition, the environmental and happiness index used in this study are not free of criticizing, and some author had disputed its efficacy. Finally, this study’s findings did not determine any causality or directionality between any of the latent variables. However, causality and directionally between environmental sustainability-happiness and happiness-academic performance have to be found in both directions.

Practical implications

Despite the unsustainability of students in this study, this study has several contributions. First, it provides an evaluation of a sustainable university from the perspectives and behaviors of students. The views of students as they relate to the complexities and visions of a sustainable university have remained relatively underexamined. Second, these analyses point to specific sustainability-oriented challenges and inadvertent barriers (e.g. extreme weather patterns) toward the embodiment of a sustainable lifestyle. These challenges and barriers suggest that sustainable universities need to address the dynamic changes inherent in sustainable development. Finally, this study indicates that the link between happiness, academic performance and sustainability may be more complicated and driven by cultural and structural barriers. The issue of barriers, as they relate to sustainability behaviors, is highly relevant and presents important opportunities and questions for future research.

Abstract

Purpose

This study aims to examine how prisoners’ early release affects other citizens’ perceived insecurity and their attitudes towards those released prisoners, and how citizens’ political orientation influences these variables.

Design/methodology/approach

A total of 383 Portuguese participants were presented with a recommendation from the United Nations for the release of prisoners because of COVID-19 and then asked to fill in a questionnaire measuring their political orientation, support for the early release of prisoners, perceived insecurity regarding such measure and their attitudes towards the released prisoners.

Findings

Results showed that support for the release of prisoners during COVID-19 is associated with perceived insecurity and both, in turn, predicts inclusive attitudes regarding these prisoners, while only perceived insecurity is associated with an agreement with an intensification of social control measures. Right-wing participants were found to express the negative side. The more participants felt insecure, the more they believed released prisoners should not have the same rights as common citizens and the more they should be left out of the community.

Research limitations/implications

The major limitation of this study concerns the sample: the authors collected answers from Portuguese participants exclusively, most of which held a university degree.

Practical implications

At least two major implications can be drawn from this study’s results. These implications deal with prisoners’ entrance in what can be considered a cycle of exclusion and the promotion of their social reintegration once they are released from prison.

Social implications

The findings point out the necessity to firstly put an effort in deconstructing the insecurity perception that results from the prospective of having prisoners back into society – that is to understand why it happens and how it can be reduced – promoting efficacy in the inclusion of these prisoners and preventing the emergence of controlling or protective approaches directed to these individuals in their return to society by enhancing people’s awareness that the social reintegration of ex-prisoners will benefit the whole community.

Originality/value

The authors present a different perspective of the impact that managing COVID-19 in prisons has on society.
