On the example of professional football in Germany, this paper analyses the conflict about the punishment of fan misbehaviour within an agency-theoretical framework to cast light on the reasons for the ineffectiveness of the sentences and to show possible solutions.

In a pre-study, more than 1,300 hand-collected past sentences against clubs by the German and European sports courts were analysed to demonstrate the ineffectiveness of the penalties so far. Additionally, in the main study, 26 expert interviews with German representatives of the football association, courts, clubs, sponsors, police and active fan scenes allow a deep insight into the relationships of the involved parties.

The paper suggests that the sentences do not sufficiently consider several agency problems. Due to moral hazard, they exert hardly any influence on fan behaviour and only a small one on the clubs. While the lighting of pyrotechnics is by far the most punished type of misbehaviour, most of the interviewees cite the impossibility of preventing it. Despite the sentences, some clubs make non-public agreements with their fans about still tolerable misconduct or do not pass the penalties on to the polluters as intended by the association. The findings highlight the importance of communication for less misbehaviour.

For the first time, the agency theory and the economic theory of optimal punishment are brought together with insights from interviews with the involved parties. The authors discover a two-stage principal-agent problem and get new insights into stakeholders' hidden motivations and attitudes. The results should encourage a debate on the current penalties and possible solutions to the recurring problem of pyrotechnics.

This paper examines the drivers of brain gain by investigating the motivations of migrants who plan to return and contribute to their home country. It focuses on highly skilled Sudanese migrants in Japan, including a group of “plan-to-return” migrants (P-group), who intend to gain knowledge abroad that they will use to contribute to their homeland upon their return.

The participants are 24 highly skilled Sudanese migrants in Japan, 10 of whom are part of the P-group. To understand their motivation to contribute to their home country, the study applies the qualitative life course approach, using Elder's four life course themes: lives in time and space, the timing of lives, linked lives and human agency.

The P-group is characterised by a high level of motivation for self-development, which motivates them to study abroad. The analysis finds that the P-group's drive to contribute had been nurtured by a spirit of mutual aid in Sudanese society, which emphasises Islamic values and social ties. Religious norms, personal interactions and emotional ties to Sudan are especially influential on the P-group's motivation to contribute to their home society.

This study identifies drivers that lead to brain gain. Whereas previous studies have noted the relationship between return intentions and willingness to contribute to the home countries; they have not investigated influences on motivations to contribute. The results suggest that Sudan might already possess a system for local human resource development to encourage brain gain.

This study answers the research question “How can businesses apply a luxury brand strategy to achieve innovation in their businesses or brands?” It aims to investigate the possibility of applying a luxury brand strategy to a wide range of business areas.

This study presents a literature review and case studies, analyzing 16 products from a selection of 8 iconic luxury brands. A survey conducted in Japan and Europe identified which of the 8 selected luxury brands had established the strongest brand image. Principal component analysis and SPSS were used to analyze the results. Scatter diagrams are used to depict the relationship between factors and product positioning. Brands and products were selected for case study analysis, and the features were generalized to show how companies in business segments other than luxury goods could apply this model.

The results showed that most of the strategy’s features apply to companies in different business areas. While luxury brand strategies are unique, their features can be generalized to stimulate innovation in other businesses or brands.

This study analyzed only two products under one luxury brand. Thus, the number of products is limited.

This study is unique because it examines how different business areas can apply the advantages of business strategy models. It illustrates the advantages of successful business strategies of luxury companies and how different companies can harness that success for future development.

The purpose of this paper is to investigate the magnetic properties and the ground state phase diagrams of the double perovskite La₂NiMnO₆ using the Monte Carlo simulations (MCS).

In this work, the authors propose a Hamiltonian modeling this compound, described by an Ising model, with different exchange coupling interactions J11, J12 and J22 between the only magnetic atoms Ni and Mn.

Starting with the ground state phase diagrams, the authors present and discuss the stable configurations in different physical parameter planes. On the other hand, the authors present the investigation of the magnetic properties and the magnetization behaviors of the magnetic susceptibilities, as a function of temperature, crystal field, the exchange coupling interactions and the Zeeman energy. To complete this study, the authors illustrate the dependency of the total magnetizations for the hysteresis loops of the double perovskite La₂NiMnO₆ compound. This study is done for fixed values of temperature, the exchange coupling interactions and crystal field.

The authors modeled the different physical parameters of the double perovskite La₂NiMnO with a Hamiltonian describing the system. At T=0K, the authors discussed the ground state phase diagrams of different physical parameters planes. For non-null temperature values, the authors studied the magnetic behavior of the double perovskite La₂NiMnO using MCS under the metropolis algorithm. The authors expect that the results of these simulations can provide some important keys for the experimental research and technology applications of the double perovskite La₂NiMnO₆ in the future.

The purpose of this paper is to understand how employees make sense of a structural change in a public organisation, in order to understand which practices form this change and how individual elements (rules, understandings etc.) may shape the process of such changes.

The research is based on: a two-wave interview method, where the same individuals from different levels of the organisation were questioned in both 2012 and 2014; and an analysis of the formal documents created during the decision-making process. Schatzki’s (1996) approach is used as the basis to identify teleo-affective structures, practical understandings and rules as constitutive elements of the practices that comprised the structural change in the organisation.

The analysis revealed two main practices – structural reorganisation and the sharing of information and involving employees – that shaped the process of structural change within the organisation. These practices are formed of positive and negative ways of doing, some of which have become in-house habits and a few which have become rules of the organisation. There were competing understandings and enactments of named elements in the organisation, indicating that organisational practices exist beyond individuals and that it takes a collective effort to change them.

The retrospective interview technique and use of employees’ subjective sense-making did not allow us to fully grasp how practices unfolded during the process of a change to the everyday workings of the organisation, which could only be accomplished by direct observations.

The research highlighted those processes that influence one of the potentially most important changes to any organisation, that of organisation structure – both extensive and compact – which has thus far seldom been studied. The authors empirically tested Schatzki’s (1996) approach to practices and provided a set of categories for analysing practices during such changes.

The paper aims to examine the role played by property tax in influencing strategic decisions regarding marital separation and divorce in Italian municipalities.

The empirical analysis is conducted on a sample of 6,458 Italian municipalities by applying the ordinary least squares (OLS) and instrumental variables (IVs) approaches.

The estimation results show a small increase in marital separations and divorces as the difference between the municipal secondary and primary home tax rate increases. Specifically, an increase of 1‰ in the property tax rate differentials is accompanied by an increase of six marital separations and four divorces per 1,000 inhabitants.

The main limitation of the analysis is that the strategic behavior of the married couple is inferred from econometric analysis with data aggregated at the municipal level. To investigate this phenomenon more precisely, it would be useful to have individual data collected by surveys on strategic divorce decisions due to property tax incentives.

This study contributes to the scant existing literature on the tax incentives for strategic divorce. It is the first study to empirically investigate the effects of property tax on separation and divorce decisions by investigating the Italian context. In Italy, a property tax was introduced in 1993, encouraging “false” divorces by spouses with a second home since the tax on the secondary home was set at a rate higher than that on the primary residence. Moreover, there were no tax deductions and no additional tax breaks on the secondary home, while they were established on the primary one. Higher property taxes and the absence of tax breaks on the secondary home may have encouraged a strategic behavior whereby many married couples filed for false separation and divorce in order to recover part of property tax rebates.

This paper seeks to determine whether family ties and structure correlate with the ethical and moral values that are important underpinnings of economic activities.

The analysis uses data from the World Values Survey (WVS). Given the multilevel nature of the data in a cross-country setting, the paper utilizes a multilevel linear mixed-effects model with maximum likelihood estimation.

Families with strong ties and those with traditional family structures are less tolerant of unethical conduct and have more restrictive moral values than households where ties are weak and the household is not married. There also appears to be a bi-causal relationship in the data.

This paper considers a broad array of values in a cross-country setting and utilizes a multilevel modeling approach that has not been done in studies linking both family ties and structure.

The purpose of this paper is to investigate the role of family structure on child labor by comparing children of nuclear families headed by the father with children of single-mother families headed by the divorced mother.

This paper uses data from Brazilian urban areas provided by the Brazilian Demographic Census of 2010. The empirical approach consists of the estimation of three treatment effect models: the Average Treatment Effect, IV Treatment Effect and Two-Stage Estimator proposed by Lewbel (2012).

The main findings show that children of single-mother families headed by divorced mothers are more likely to work, compared to children living with both parents. This paper found evidence of a direct effect of family structure parents’ determinant on child participation in labor. The main hypothesis is that the absence of the father paired with exposure to family stress arising from marital dissolution is an indicator toward child labor.

This study implies that in order to combat child labor effectively, it is important to understand deeply its several causes and consider ruptures in family structure, such as divorce, as one of these factors. In addition, location and family’s characteristics also play a role on the decision of child labor. For instance, boys living at metropolis areas have less chance to work. Family’s head education and non-work income affects positively the child well-being by reducing the probability of child labor. On the other hand, the number of siblings increases the chance of child labor. Finally, the results of this study suggest policies to raise awareness among parents about the negative effects of child labor on children during both childhood and adulthood, and that social policies need to act beyond legislation and enforcement, but including family mobilization.

This paper estimates the impact of family structure on child labor using an empirical approach to deal with the endogeneity problem of the treatment.

The purpose of this paper is to outline a service evaluation that gathered feedback from people with a learning disability on their experience of lockdown in Jersey and Guernsey. This feedback was intended to guide planning for service provision during any future lockdown and for life as we exit lockdown.

An accessible survey was sent to everyone accessing learning disability services across the two islands and Mencap in Jersey. Data was analysed quantitatively and qualitatively to identify patterns in the data and key themes.

Most respondents felt safe, calm and happy and valued support from services. Key themes emerging from the data included the importance of relationships, messages of safety, keeping busy and communication.

This survey has been undertaken at a time where there is a paucity of research and consultation with individuals with a learning disability self-reporting on their experiences of lockdown, during the COVID-19 pandemic.
