The paper presents a new variant of the H-Φ field formulation for solving 3-D magnetostatic and frequency domain eddy current problems. The suggested formulation uses the vector and scalar tetrahedral elements within conducting and non-conducting domains, respectively. The presented numerical method is capable of solving multiply connected regions and eliminates the need for computing the source current density and the source magnetic field before the actual magnetostatic and eddy current simulations. The obtained magnetostatic results are verified by comparison against the corresponding results of the standard stationary current distribution analysis combined with the Biot-Savart integration. The accuracy of the eddy current results is demonstrated by comparison against the classical A-A-f approach in frequency domain.

The theory and implementation of the new H-Φ magnetostatic and eddy current solver is presented in detail. The method delivers reliable results without the need to compute the source current density and source magnetic field before the actual simulation.

The proposed H-Φ produce radically smaller and considerably better conditioned equation systems than the alternative A-A approach, which usually requires the unphysical regularization in terms of a low electric conductivity value within the nonconductive domain.

The presented numerical method is capable of solving multiply connected regions and eliminates the need for computing the source current density and the source magnetic field before the actual magnetostatic and eddy current simulations.

In this chapter, the authors examine the use of deceit to drive routine emergence. The authors do so by tracing the relationship among deceit, roles, and routine dynamics in the context of Romeo pimps and the women they lure into sex trafficking. Previous research has focused on routine participants openly negotiating their roles and expected interactions during the (re) creation of routines. In contrast, this study shows how Romeo pimps use deceit to control the co-constitution of roles and increasingly coercive actions of the “Romeo pimp routine” – a process of premeditated routine emergence designed to entrap the women. The authors contribute to the literature on routine dynamics by emphasizing the unexplored influence of deceit on the interplay between roles and routines. Bringing deception to center stage in routine dynamics highlights the importance of linking actors and actions to motivations that exist behind the veil of transparently observable behavior.

More than 50 per cent of all German households own a freezing appliance and so far the market of frozen foods is constantly increasing (1 per cent from 2017 to 2018). Despite frozen foods playing an important role in our everyday life, little is known about the consumer’s habits at home. The purpose of this paper is to uncover gaps in the knowledge about consumer behaviour when handling frozen food. Moreover, the impact of consumers on the quality of frozen products should be assessed.

A representative online survey was carried out to investigate different aspects of consumer behaviour concerning frozen foods. Respondents (n=2,053) were questioned about their general handling habits regarding eight different food groups: fruit, vegetables, meat, fish, bread, pastries, ready-to-eat meals and leftovers. The focus was on freezing, pre-handling, packaging and thawing – depending on the age of those questioned and combined with best practice advice regarding quality storage of frozen products.

Most Germans have the opportunity to freeze food and keep their freezers full or medium loaded. Older participants act more efficiently towards quality storage, but more education about freezing and frozen storage would be generally helpful to maintain quality of frozen foods and increase utilisation of freezers, using their full preservation potential.

No open questions were asked due to the scope of more than 2,000 participants, which, in retrospect, would have been instructive.

Consumer handling of frozen food in Germany was investigated in a representative way for the first time, covering age groups from 18 to 69 and household sizes from 1 to >4 people, focussing on eight major food groups.

The Children's Depression Rating Scale-Revised (CDRS-R) is a widely used instrument for research on depression in minors. A raw score of ?40 has often been used as indicator of depressive symptomatology. As a validated German version of the CDRS-R has recently became available, we assessed CDRS-R raw summary scores of a video taped interview session in two different rater groups and compared them with clinical ratings of International Classification of Diseases (ICD-10) depression diagnosis as observed by a third independent group. We found that for the German version a raw score between 35 and 40 is indicative for mild depressive symptomatology as described by the ICD-10. CDRS-R scores show potential clinical applicability to deduct levels of depression.

Purpose – We build a theoretical lens that draws on an emerging theory of positive work relationships to examine whether constructive emotional expressions in work relationships influence changes in individuals' affective commitment to their organization.

Design/methodology/approach – Using longitudinal data collected from full-time employees, we employed a latent-difference-score (LDS) approach to examine whether changes in emotional carrying capacity could account for changes in organizational commitment.

Findings – The findings support this hypothesis and suggest a new perspective on the ways in which a change in relationship capacity may create changes in people's commitment to an organization.

Research limitations – The main limitation concerns the use of self-report, albeit time-lagged, data.

Practical implications – Developing higher levels of employee affective commitment is a key challenge for many organizations. Our study can help managers in recognizing the importance of building a relational space in which employees are able to express emotions frequently and openly, as well as engaging with other employees in listening to their emotional experiences and responding in a constructive manner.

Originality/value – This study contributes to an emergent body of literature that adopts a positive psychology lens to the study of employee experiences at work, by investigating the capacity to express emotions in general and its influence on people's affective commitment to the organization.

The purpose of this paper is to examine the effect of the presence of political connections on firm performance through related party transactions in Tunisia, a country where that is characterized by the Jasmin revolution in 2011.

The study uses a sample of nonfinancial firms between 2008 and 2014 listed on the Tunis Stock Exchange and uses generalized least squares on panel data.

First, the political connection and related parties' transaction enhances firm's market performance. Second, the study reveals that political connection moderates the relationship between the related party transactions and firm performance only in the period after revolution. Indeed, politicians seem to have used related party transactions to expropriate firms in a period of political instability. Finally, we show that politicians are more attracted by firms with higher market performance and with higher number of related parties' transactions.

The empirical findings contribute to the current debate on the benefits and costs of political connections in emerging economies. It shows that political connections enhance market valuation of firms. However, political connection costs appear during political instability period.

This study addresses the interaction between related party transactions, political connections and firm performance. It is the first study to test if the related party transactions are used as a tool by politicians to expropriate firms.

The purpose of this study is to qualitatively explore the views and opinions of service users accessing remote therapy through a community forensic personality disorder service during the COVID-19 pandemic.

A qualitative exploratory approach was adopted. Nine community forensic service users accessing virtual/telephone therapy through a community forensic mental health service were interviewed using semi-structed interviews. Data was analysed using Braun and Clarke (2006) thematic analysis techniques.

Analysis resulted in three overall themes: experience of communication in the therapeutic relationship; impacts of the change to remote working and making the best of what we have. A further seven subthemes were developed. A range of advantages and disadvantages to remote therapy were highlighted.

This study was based on a small sample of service users accessing one community forensic service in England, and therefore caution should be taken when generalising the findings. All interviews were conducted remotely and thus may have only supported those who are able to engage in this way.

This paper has the potential to inform future remote therapy guidelines. Health services should consider keeping some elements of remote working and offering this as a choice to all service users.

This study is, to the best of the authors’ knowledge, the first study that attempts to explore the experiences of individuals accessing remote therapy within a forensic population who have personality disorders or traits.

This chapter discusses the high adoption of plastic bags/packages by food providers in Malaysia during pandemic that resulted in a long-time lockdown. Under the federal government act of ‘Movement Order Control’ (MCO), people had no choice but to order food or purchase food ingredients via online food delivery services. Such situation made the food delivery business instantly one of the top and essential economic contributors. However, this also severely impacted our environment specifically the growing usage of plastic bag, plastic food container, and parcel packaging. While the food delivery company introduces a campaign to reduce and replace the plastic bag/packages, the awareness level is still very low. This chapter highlights the introduction of food delivery business striving in the COVID-19 pandemic, the severity of plastic usage and challenges of sustainability marketing campaign in Malaysia.

The purpose of this paper is to evaluate the service quality automobile garages through development of a service quality index based on the factors influencing service quality.

A structural methodology of graph theory and matrix approach is applied for developing the service quality index.

The automobile maintenance can be considered as a service industry and in order to sustain in the competitive business environment, the service providers must ensure quality in their services. There are several factors that influence the service quality. Each factor is comprised of several sub-factors. Moreover, the factors are interrelated with each other. Modelling of these factors and their interrelations with due consideration of their structure is accomplished through the graph theory. The directed graph (digraph) of the service quality is defined; the nodes of this symbolize the quality influencing factors, while the edges represent their degrees of interrelationships. An equivalent matrix developed from the digraph establishes a service quality function which leads to evaluation of service quality index (SQI). A greater value of the service quality index displays that the organization and functioning of the garage is adequate.

The methodology can be applied for evaluating as well as comparing service quality of different garages. The observations would be helpful to the managers the garages to make strategies for improving their service quality.

The paper establishes the interrelations among various factors that influence the service quality at automobile garages and develop a numeric index for the evaluation of the same.

The purpose of this paper is to investigate the application of key performance indicators (KPIs) on shop floor level in German small- and medium-sized enterprises (SMEs). The paper focuses on the examination of perception differences between shop floor employees and managers with regard to collection, calculation and consolidation of KPIs as well as visualization and motivational aspects.

To examine the hypothesis on differing perceptions regarding KPIs, 27 qualitative interviews with shop floor employees and production managers within 6 SMEs from the German machinery and equipment industry were conducted on basis of a semi-structured guideline.

The findings show that shop floor employees self-assess a lack of relevant knowledge when it comes to understanding KPIs. Moreover, the results show that shop floor employees perceive the visualization of shop floor KPIs as insufficient and non-motivational. This goes along with the finding that managers are aware of the lacking benefit of KPIs resulting from the rather negative perception of shop floor employees. The interviewed managers recognize a strong potential for improvement of their KPI systems.

The interview results confirm the need to design a performance management system on the shop floor that considers and aligns both management and operations, is directed to the shop floor level, considers explicitly the perspective of employees and integrates motivational elements.
