Performing accurate numerical simulations of electrical drives, the precise knowledge of the local magnetic material properties is of utmost importance. Due to the various manufacturing steps, e.g. heat treatment or cutting techniques, the magnetic material properties can strongly vary locally, and the assumption of homogenized global material parameters is no longer feasible. This paper aims to present the general methodology and two different solution strategies for determining the local magnetic material properties using reference and simulation data.

The general methodology combines methods based on measurement, numerical simulation and solving an inverse problem. Therefore, a sensor-actuator system is used to characterize electrical steel sheets locally. Based on the measurement data and results from the finite element simulation, the inverse problem is solved with two different solution strategies. The first one is a quasi Newton method (QNM) using Broyden's update formula to approximate the Jacobian and the second is an adjoint method. For comparison of both methods regarding convergence and efficiency, an artificial example with a linear material model is considered.

The QNM and the adjoint method show similar convergence behavior for two different cutting-edge effects. Furthermore, considering a priori information improved the convergence rate. However, no impact on the stability and the remaining error is observed.

The presented methodology enables a fast and simple determination of the local magnetic material properties of electrical steel sheets without the need for a large number of samples or special preparation procedures.

In the big data era, image compression is of significant importance in today’s world. Importantly, compression of large sized images is required for everyday tasks; including electronic data communications and internet transactions. However, two important measures should be considered for any compression algorithm: the compression factor and the quality of the decompressed image. In this paper, we use Frei-Chen bases technique and the Modified Run Length Encoding (RLE) to compress images. The Frei-Chen bases technique is applied at the first stage in which the average subspace is applied to each 3 × 3 block. Those blocks with the highest energy are replaced by a single value that represents the average value of the pixels in the corresponding block. Even though Frei-Chen bases technique provides lossy compression, it maintains the main characteristics of the image. Additionally, the Frei-Chen bases technique enhances the compression factor, making it advantageous to use. In the second stage, RLE is applied to further increase the compression factor. The goal of using RLE is to enhance the compression factor without adding any distortion to the resultant decompressed image. Integrating RLE with Frei-Chen bases technique, as described in the proposed algorithm, ensures high quality decompressed images and high compression rate. The results of the proposed algorithms are shown to be comparable in quality and performance with other existing methods.

Artifacts are rarely used today to visualize thoughts, insights, and ideas in strategy work. Rather, textual and verbal communication dominates. This is despite artifacts and visual representations holding many advantages as tools to create and make sense of strategy in teamwork. To advance our understanding of the benefits of visual aids in strategy work, I synthesize insights from cognitive psychology, neuroscience, and management research. My analysis exposes distinct neurocognitive advantages concerning attention, emotion, learning, memory, intuition, and creativity from visual sense-building. These advantages increase when sense-building activities are playful and storytelling is used.

The purpose of this study is to extend the research on fashion renting (FR) by investigating how personal and social motives (i.e. “subjective norms”, “perceived behavioural control”, “sustainable orientation” and “FR benefits”) affect consumers’ attitudes and intentions towards it. In addition, personality traits are investigated as potential antecedents of FR, resulting in the proposal of an overall framework that combines the theory of planned behaviour with the trait theory approach.

Data were collected in Italy from a sample of 694 consumers, mainly females (88%), with an average age of 28.8 years and coming from all over the country. The collected data were then processed via structural equation modelling.

The results indicated that intention towards FR is influenced by attitude, which, in turn, is affected by social norms, perceived behavioural control, sustainable orientation and FR benefits. Furthermore, only fashion leadership acts as a direct antecedent of FR attitude, while the need for uniqueness and materialism plays critical roles as predictors of personal and social motives. Subjective norms and perceived behavioural control also serve as mediators of the significant relationships between personality traits and attitudes towards FR.

The study provides useful implications for fashion rental companies in attracting consumers and offers a foundation for further research on transforming traditional consumption into a more sustainable one.

The study presents new knowledge on the rental phenomenon in the fashion sector by responding to the call to deepen the analysis of factors that influence consumers’ adoption of FR from the perspectives of personal and social motives and personality traits.

The type of social capital among families involved in business, or family social capital, has both positive and negative effects on family firms. This paper aims to investigate the mediating role of social relationships of family business members between socioemotional wealth (SEW) and firms' entrepreneurial orientation.

The authors applied a survey conducted in the four main cities in Mexico. The sample consisted of 360 small and medium enterprise (SMEs). This study's research framework and hypothesis were tested using regression analysis and the structural equation modeling technique.

This study finds that not only does SEW strongly influence the entrepreneurial orientation of family firms, but this influence is also mediated by the capability of such families to develop their social capital.

The results show the perspective of one person in the company. Though it is the person with the highest rank and presumably the person who thoroughly knows the company, there is always a possibility of bias, which may inflate the results presented in this paper.

Based on this study's results, family firms should continuously improve their entrepreneurial abilities to achieve sustainable competitive advantage. In addition, their unique family-related characteristics further enhance these strategic approaches' positive effects on relational capital development.

This work contributes to the academic literature on entrepreneurship and social capital. As a mediator between SEW and entrepreneurial orientation, family relational capital has been under-researched. The results of this study reveal significant implications for networking management and relational capital strategies for SMEs.

The authors conduct a structured analysis of the literature on the determinants of economic and financial franchise performance and develop an integrative framework that unifies the literature from franchisor as well as franchisee perspectives.

53 relevant research articles on economic and financial franchise success published between 1976 and 2020 were identified. After providing an overview of the empirical methods and theoretical perspectives found in the literature, an original classification system of franchise success determinants was developed.

More than 50 different variables impacting economic or financial franchise success were identified and grouped into ten distinct categories. The most impactful categories are the franchise relationship, franchisee characteristics and capabilities, franchisor variables and the franchise environment. The study’s integrative framework illustrates not only the impact of these factors on franchise success, but also reveals which areas require more attention.

As the study focused on understanding the determinants of franchise success, any measures related to franchise failure were excluded. Also, the role of venture capital and stock market listing as growth strategies in the franchise sector were excluded.

The study’s framework shows how the management of franchise success is complex and that franchise relationship, franchisee and franchisor variables as well as the franchise context need to be taken into account. It illustrates that there is a hierarchy with which these determinants should be prioritized.

The article proposes the first systematic review of the literature on the determinants of economic and financial franchise success. The contribution offers both, researchers and practitioners, new and useful insights for future knowledge development in the field.

The aim of this study is to test for a moderating role of employee participation in volunteering in links between employees' relationships with peers and supervisors, work meaningfulness (WM) and affective commitment (AC).

The study is based on a survey conducted on a sample of 711 employees, both those involved and those non-involved in corporate volunteering (CV).

The results suggest that employee participation in CV strengthens the effects that employees' perceptions of positive relationships with peers and perceived supervisor support (PSS) have on employees' AC. Contrary to expectations, although participation in CV strengthens employees' sense of WM, it does not affect its links with other phenomena analyzed in this study.

CV is a fast-growing practice in corporate social responsibility. The reasons companies implement CV include the benefits they gain from it, such as positive effects on employee attitudes and behaviors. The paper contributes to the understanding of CV effects on employee attitudes and behaviors and builds a better business case for this CSR practice.

After completion of the case study, the students will be able to gain knowledge on public–private partnerships (PPPs) in emerging markets; understand how to apply the sensing element of the dynamic capabilities framework in analysing context, especially in emerging market context; and understand how to apply the dynamic capabilities framework to the process of developing brand equity.

On 20 March 2020, in Johannesburg South Africa, Dr Barbara Jensen Vorster, the head of corporate communications and marketing at the Gautrain Management Agency, was considering her dilemma of how to manage stakeholders at a time when the patronage guarantee was under question. The nature of the Gautrain PPP transport contract entailed a revenue guarantee that was called a patronage guarantee. How did they build their Gautrain brand equity during the Gautrain PPP patronage guarantee controversy? This case study highlights the perspectives of multiple stakeholders which places the Gautrain brand equity under strain. The Gautrain brand identity was created to project an integrated, overarching brand position for the construction project and later the operating company. The logo illustrated Africanisation, and the slogan “For People on the Move” represented a modern collaborative approach. Upholding the status of the brand is an important quest for the corporate communications and marketing team, and therefore the issue around the patronage guarantee must be addressed. This case study illustrates contrasting views about the Gautrain being elitist versus the rapid rail train enabling economic prosperity. The pro-prosperity versus pro-economic development values were at the heart of the different opinions around the patronage guarantee. Students are therefore confronted with their own values while the case study aims to drive an awareness or consciousness around these issues in an emerging market.

This case study is appropriate for advanced undergraduate and Master of Business Administration courses focused on marketing, communications and/or stakeholder management, such as in business and society courses. At both levels, the case study will be valuable in generating discussion on communications models and how to manage stakeholders ranging from government to community representatives. In courses where dynamic capabilities theory is taught, this case study will offer a specific application of this model in the context of brand communications and building brand equity in times of controversy.
