This paper aims to propose and evaluate an innovative approach to education for sustainable consumption (ESC) which empowers teenagers and young adults to improve sustainable consumption competences. This approach combines pedagogical learning approaches such as real-world learning (e.g. experiential learning and research-based learning) with transformative and transdisciplinary research approaches (i.e. real-world laboratory research).

Through a transdisciplinary research design, the authors explore if real-world experiments (RWEs) offer a suitable approach for sustainable consumption education at schools. RWEs are a research approach for knowledge production, aiming to go beyond temporary interventions, to establish semi-permanent spaces for sustainability transformation and reflexive learning. To evaluate this proposal, the authors study already existing active teaching and learning approaches developed within and for ESC and put these in perspective, to define and understand the RWEs.

Insights from a transdisciplinary research project which applied RWEs as a teaching and learning approach in German schools complement conceptual considerations. As a result, advantages, such as the development of core competencies among learners, but also challenges experienced, are illustrated. Though, the challenges found are not unique to the RWE, rather they point out important potentials for ESC through suggesting systematic changes in educational institutions and teaching approaches.

This paper explores RWEs as an active and participatory teaching and learning approach for sustainable consumption education at schools and delivers practical insights and a definition of RWEs as an innovative teaching and learning approach.

The purpose of this paper is to analyze the relationships between coordination mechanisms (CMs) and quality requirements used to support transactions in the Brazilian pork chain.

Based on the transaction cost economics theory, the paper focuses on the alignment between CMs and quality requirements. The results were obtained by means of interviews (n=41) with public and private actors, including the main companies and other stakeholders in the Brazilian pork sector. The research addresses regulations, requirements of customers and supporting CMs used in different transaction contexts.

In the Brazilian pork sector, five transaction contexts can be distinguished: spot market, mini integration, singular cooperative, central cooperative and investor-owned firm. The chain actors apply different CMs to support a set of quality requirements which presents little diversity. The main quality requirements are driven by baseline public regulations. Besides, there are, in particular international, customers with more specific requirements. To support transactions, chain actors use different contracts in terms of resource allocation and price incentives.

Literature assumes alignment between governance structures (GSs) and quality standards. This paper further investigates this assumption by analyzing the relationships between CMs (underlying GSs) and quality requirements (underlying quality standards). The research findings show that similar quality requirements may well be supported by different CMs. It further gives indications on why different CMs are used to support a homogeneous set of requirements.

The ordinary vector hysteresis stop model with constant threshold values is not able to prohibit the hysteretic property after the saturation correctly. This paper aims to develop an improved vector hysteresis stop model with threshold surfaces. This advanced anisotropic vector hysteresis stop model can represent the magnetic saturation properties and the hysteresis losses under alternating and rotating magnetizations.

By integrating anhysteretic surfaces into the elastic element of a vector hysteresis stop model, the anisotropy of the permeability of an electrical steel sheet can be represented. Instead of the commonly used constant threshold value for plastic elements of the hysteresis model, threshold surfaces are applied to the stop hysterons. The threshold surfaces can be derived directly from measured alternating major loops of the material sample. By saturated polarization, the constructed threshold surfaces are vanishing. In this way, the reversible magnetic flux density is in the same direction of the applied magnetic flux density. Thus, the saturation properties are satisfied.

Analyzing the measurements of the electrical steel sheets sample obtained from a rotational single sheet tester shows that the clockwise (CW) and counter-CW (CCW) rotational hysteresis losses decrease by saturated flux density. At this state, instead of the domain wall motion, the magnetization rotation is dominant in the material. As a result, the hysteresis losses, which are related to the domain wall motion, are vanished near the saturation. In one stop operator, the plastic element represents the hysteresis part of the model. Integrating threshold surface into the plastic element, the hysteresis part can be modified to zero near the saturation to represent the saturation properties.

The results of this work demonstrate that the presented vector hysteresis stop model allows simulation of anisotropic hysteresis effects, alternating and rotating hysteresis losses. The parameters of the hysteresis model are determined by comparing the measured and modeled minor loops in different alternating magnetization directions. With the identified parameters, the proposed model is excited with rotated excitations in CW and CCW directions. The rotated hysteresis losses, derived from the model, are then compared with those experimentally measured. The modified vector stop model can significantly improve the accuracy of representing hysteresis saturations and losses.

This chapter compares interdisciplinary research that engages genomic science from economics, political science, and sociology. It describes, compares, and evaluates concepts and research findings from new and rapidly developing research fields, and develops a conceptual taxonomy of the social environment.

A selection of programmatic and empirical articles, published mostly since 2008 in leading economics, political science, and sociology journals, were analyzed according to (a) the relationship they pose between their discipline and genomic science, (b) the specific empirical contributions they make to disciplinary research questions, and (c) their conceptualization of the “social environment” as it informs the central problematique of current inquiry: gene-environment interaction.

While all three of the social science disciplines reviewed engage genomic science, economics and political science tend to engage genomics on its own terms, and develop genomic explanations of economic and political behavior. In contrast, sociologists develop arguments that for genomic science to advance, the “environment” in gene-environment interaction needs better theorization and measurement. We develop an approach to the environment that treats it as a set of measurable institutional (rule-like) arrangements, which take the forms of neighborhoods, families, schools, nations, states, and cultures.

Interdisciplinary research that combines insights from the social sciences and genomic science should develop and apply a richer array of concepts and measures if gene-environment research – including epigenetics – is to advance.

This chapter provides a critical review and redirection of three rapidly developing areas of interdisciplinary research on gene-environment interaction and epigenetics.

Zusammenfassung Die vorliegenden Ergebnisse des “Workshop 2” verdeutlichen, daß intensiv nach einem gemeinsamen Verständnis zur strategischen Tourismuspolitik in Abgrenzung der Felder Tourismuspolitik (policy) und — Strategie gesucht und dieses Verständnis in den genannten Modellen festgehalten wurde. Trotzdem haben gerade die Fallbeispiele gezeigt, daß jede spezifische Situation verschieden handzuhaben ist und deshalb auch unterschiedliche methodische Ansätze zur Analyse der Fallstudie herangezogen worden sind. Auch konnte die Begriffsverwendung von Tourismus‐politik und Strategie nicht immer eindeutig zugeordnet werden. Ein allgemein gltiges Rahmenmodell — wie in Kapitel 3 und vier aufgezeigt — ist deshalb nur erschwert im Detail darstellbar. Zur Notwendigkeit einer strategischen Tourismuspolitik ist insgesamt eine große Übereinstimmung festzuhalten.

Research on racial inequality in organizations typically (1) assumes constraining effects of bureaucratic structure on the capacity of powerful actors to discriminate or (2) reverts to individualistic interpretations emphasizing implicit biases or self-expressed motivations of gatekeepers. Such orientations are theoretically problematic because they ignore how bureaucratic structures and practices are immersed within and permeated by culturally normative racial meanings and hierarchies. This decoupling ultimately provides a protective, legitimating umbrella for organizational practices and gatekeeping actors – an umbrella under which differential treatment is enabled and discursively portrayed as meritocratic or even organizationally good. In this chapter, we develop a race-centered conception of organizational practices by drawing from a sample of over 100 content-coded workplace discrimination cases and analyzing both discriminatory encounters and employer justifications for inequality-generating conduct. Results show three non-mutually exclusive patterns that highlight the fundamentally racial character of organizations: (1) the racialization of bureaucracies themselves via the organizational valuation and pursuit of “ideal workers,” (2) the ostensibly bureaucratic and neutral, yet inequitable, policing of minority worker performance, and; (3) the everyday enforcement of racial status boundaries through harassment on the job, protection afforded to perpetrators, and bureaucratically enforced retaliation aimed at victims. The permeation of race-laden presumptions into organizations, their activation relative to oversight and bureaucratic policing, and the invoking of colorblind bureaucratic discourses and policies to legitimate discriminatory conduct are crucial to understanding the organizational dimensions of racial inequality production. We end by discussing the implications of our argument and results for future theory and research.

The purpose of this paper is to examine the presence of exchange rate exposure and its relationship with currency derivatives usage in the dynamic environment of the global financial crisis of 2008.

Using a sample of 624 Indian firms over the period of April 2001–March 2016, this paper investigates the linear and asymmetric exposure by dividing the full sample period into different sub-periods around the crisis.

The evidence presented in the paper suggests that the firms are more exposed to the exchange rate changes since the onset of the financial crisis. However, there is a lack of evidence that the usage of currency derivatives is more effective in reducing exposure during the crisis/post-crisis period as opposed to the pre-crisis period.

The findings are important to investors and managers for a better understanding of firm behaviours in relation to their risk management policies during the period of external shocks like crisis.

There is a paucity of research to explore whether the effect of currency derivatives usage on exchange rate exposure varies during external shocks such as crisis periods. The paper provides novel evidence that the effectiveness of derivatives usage in alleviating exposure becomes less during the dynamic environment of crisis.

This paper aims to present an in‐depth review on the latest state of empirical research in transaction cost economics (TCE), focusing on single‐industry studies. The intensely discussed subject of operationalization of transaction costs is critically assessed, and a concept of how to increase the quality of findings in empirical studies is presented.

The sample was obtained by a literature research and review in high‐class media and submitted to in‐depth quantitative and qualitative analysis such as content analysis.

The findings are in part unexpected and substantially contribute to research: applicability of TCE to a broad range of industries is found, the majority being large industries with important markets. Most studies support TCE statements, some suggesting theory extension by complementary aspects. Operationalization of transaction costs remains a field requiring further research.

First, this article is condensed and therefore limited to single‐industry studies within TCE, understanding “industry” as a specialized field of activity. The question of industry boundaries may be a base for future research. Second, the subject of operationalization of transaction costs still requires further research.

Decision makers can continue to use TCE for various applications such as strategic alliance, vertical integration, governance choice, make‐or‐buy or contract choice questions. A shortcoming in most articles reviewed is the presentation of the industry's characteristics. Authors need to consider them in order to increase the qualitative level of single‐industry studies.

This paper provides significant insight into the field of single‐industry TCE studies. As a result of penetrating research in high‐class media and in‐depth analysis, the paper provides highly structured and intensely examined statements on existing literature and related findings, which support TCE statements and will lead current disputes in the literature to a further stage.

The South African construction industry is undergoing transformation. Part of this metamorphosis is the explosion in the number of “emerging contractors”. However, emerging contractors have a tendency to fail to develop into sustainable enterprises due to inadequate construction knowledge and lack of experience. These shortfalls can be potentially overcome by learning through appropriate interactions with others who possess the required knowledge and experience but there is an absence of comprehensive data about the form and frequency of such interactions and reliance has tended to be on small scale samples or anecdotal reports. The paper aims to address these issues.

A survey amongst emerging contractors on interactions in the civil engineering sector was carried out, collecting mainly quantitative but also qualitative data for analysis.

Significant relations between particular forms of interactions and knowledge perceived to be held by the respondents exist. Interdependencies between interactions and knowledge levels are present. Yet, the findings indicate that these interactions are not fully capitalised on in terms of knowledge gains by the respondents.

Using the conceptual framework of the Basho, as introduced by Nonaka, the knowledge of patterns of interactions with indicators of knowledge‐interaction interdependencies are of interest. Mapping these allows for the relevant existing learning contexts and knowledge transfer mechanisms to be explored and described.

The purpose of this article is to identify the critical success factors (CSFs) of information technology (IT) projects using cloud computing. CSFs are variables that can influence the success of projects and therefore need to be identified and managed appropriately.

This is an exploratory qualitative study with 23 experts in cloud computing projects through semi-structured interviews. The data was analyzed using content analysis.

The results present a list of CSFs for projects in a cloud computing environment. The study demonstrated that the CSF with greater relevance to cloud projects is the team’s technical capacity, followed by the support of senior management and the team’s soft skills. In addition, results demonstrated that contract item management is a limiting factor for cloud projects.

The sample comprised only Brazilian experts, so it may not represent the same scenario as in other locations. The CSF ratio for cloud computing projects may vary depending on the company’s maturity in projects of this nature.

The CSF relationship can guide managers in properly conducting cloud computing projects, contributing to minimizing the risks and challenges that may interfere with the project.

The relationship of the CSFs in cloud computing projects proposed fills a gap in studies specifically related to this context and tries to minimize project managers’ stress.

Contract items for the cloud context are added to the CSF literature in IT projects, which have not been addressed so far.
