Abstract
Purpose
Climate change, poverty and pandemics are some of the complex real-world problems that are increasingly challenging higher education institutions (HEIs) to equip future graduates with meta-competences that have hitherto not been demanded. These graduates need to be able to capture and operate within complex systems and relationships. By focusing on complex real-world problems, this study aims to systematically review competences and frame meta-competences supporting curricula development in HEIs.
Design/methodology/approach
This study applies a systematic literature review according to the review protocol of Preferred Reporting Items for Systematic Reviews and Meta-Analyses. The review process resulted in the selection of 39 articles, which were subjected to qualitative synthesis to identify competences for tackling complex real-world problems. These competences were grouped into meta-competences and aligned with the Sustainable Development Goals (SDGs).
Findings
Scientific disciplines commonly describe four competences for tackling complex real-world problems including domain-specific competence, inter-relation competence, intrapersonal competence and normative competence.
Originality
This study found that inter-relation competence is in line with all the SDGs, which is considered important for tackling complex real-world problems across disciplines.
Research limitations/implications
A study in a survey design across disciplines and a weighting of these competences in respect to complex real-world problems aligned with the SDGs could contribute to a more consolidated and common understanding of the meta-competences identified.

Abstract
Since Bram Stoker’s tale of Count Dracula struck a chord with a sensation-hungry public, vampires have remained a popular part of horror in cinema. Since the turn of the millennium, vampires have now become a mainstay of horror TV. Programmes like True Blood (2008–2014) and The Vampire Diaries (2009–2017) have propelled the vampire into the home.
This chapter will investigate the problematic, but often sympathetic relationship between vampires and humans in The Vampire Diaries.

Abstract
Purpose
Operation of synchronous machines in the power range of several 10 MW with variable speed up to 7,000 rpm using a current converter is, thanks to the development of power switches, possible and economically reasonable today. However, current harmonics, produced by converter, generate additional losses, especially eddy current losses on the rotor surface are produced by the converter, which strongly depend on the rotor permeability. The purpose of this paper is to show that an accurate machine modeling is required, in order to consider the nonlinearity of electromagnetic processes inside.
Design/methodology/approach
This paper concentrates on the determination of the rotor surface losses in a three‐phase turbogenerator feeding a current converter. Saturation of rotor steel is taken into account using a transient finite element method model of the machine, coupled with a converter model.
Findings
A detailed analysis of the damper currents and losses in a turbogenerator operating with a frequency converter is presented. The effectivenes of damper winding modifications, concerning the eddy current loss reduction in the rotor surface, is depicted.
Practical implications
The introduced modelling technique presents an accurate electromagnetic modelling of an I‐converter‐fed synchronous generator with massiv poles, which is fed by a current converter and so has to sustain additional eddy current losses in the rotor surface. In this way, the amount and distribution of these losses are evaluated more accurately which allows a more efficient design of the damper winding as well as machine cooling system.
Originality/value
Some researchers have made contributions to the analysis of current converter‐fed synchronous machine, regarding terminal behaviour of the machine. This paper focuses on eddy current losses on the rotor surface, considering the time and space dependent saturation aspect in the machine, particularly in the rotor.

Abstract
Purpose
The purpose of this paper is to progress operations management theory and practice by organising contributions to knowledge production, in industrial sustainability, from disparate researcher communities. It addresses the principal question “What scholarly dialogues can be explicated in the emerging research field of industrial sustainability?” and sub-questions: what are the descriptive characteristics of the evidence base? and what thematic lines of scientific inquiry underpin the body of knowledge?
Design/methodology/approach
Using an evidenced-based approach, a systematic review (SR) of 574 articles from 62 peer-reviewed scientific journals associated with industrial sustainability is conducted.
Findings
This paper distinguishes three prevailing dialogues in the field of industrial sustainability, and uses Kuhn’s theory of paradigms to propose its pre-paradigmatic scientific status. The three dialogues: “productivity and innovation”, “corporate citizenship” and “economic resilience” are conjectured to privilege efficiency strategies as a mode of incremental reductionism. Industrial sustainability espouses the grand vision of a generative, restorative and net positive economy, and calls for a future research trajectory to address institutional and systemic issues regarding scaling-up and transition, through transformative strategies.
Research limitations/implications
The review is limited by the nature of the inquiries addressed in the literatures by specific researcher communities between 1992 and 2014.
Originality/value
This study performs the first SR in the field of industrial sustainability, synthesises prevailing scholarly dialogues and provides an evaluation of the scientific status of the field.

Abstract
Purpose
This paper aims to illustrate by means of a case study how HKT-R Spider reference profiles of recidivists and non-recidivists may be supportive in leave decisions.
Design/methodology/approach
The authors describe what is known for recidivists and non-recidivists about changes in risk factors during treatment. The HKT-R Spider is introduced. By comparing a case study to group profiles, the authors illustrate how discussions about leave may be rationalised. From a study among 278 patients to explore the profiles, the authors report the inter agreement, and differences between recidivists and non-recidivists of the clinical HKT-R factors. Intra correlation coefficients, Wilcoxon signed ranks test and independent and paired t-tests are applied. To explore which combination of factors are discriminating between both groups, the authors also performed logistic regression analyses at six treatment stages.
Findings
The inter agreement reliability and internal consistency of the clinical HKT-R scale were acceptable to good in all six stages studied. The HKT-R Spider and profiles can be used to assist in evidence-informed decision-making about leave.
Practical implications
Globally recidivists had somewhat higher levels of clinical risk factors at all six decision moments, but the interpretation of HKT-R Spiders profiles should always be adapted to the individual’s context.
Originality/value
Applying the HKT-R Spider reference profiles on individual cases may structure and rationalize discussions lead to decisions based on clinical facts.

Abstract
This chapter utilizes German tax data to present evidence about the direct and indirect effects of new firm formation. Cohort analysis is applied to investigate survival, sales, inputs, and value added of start-up firms. Most dropouts occur in the early years. We show that start-up microenterprises increase economic vitality directly. Sales and value added are in an approximate proportion of 3:1. With respect to the indirect effects of new firms, we find that one Euro of sales induces considerable indirect effects because 66 Cents are used to buy products and services from incumbents. For this reason, new firms substantially promote economic prosperity of incumbents. Sectoral differences are also indicated, with the manufacturing industry generating highest sales and relying most heavily on inputs in the early periods.

Abstract
Purpose
Global and interconnected supply chains are increasingly exposed to systemic risks, whereby individual failures propagate across firms, sectors and borders. Systemic risks have emerged from the decisions of individual firms, e.g., outsourcing and buffer reduction, and are now beyond their control. This paper aims to identify appropriate approaches to mitigating those risks.
Design/methodology/approach
Systemic risks require analyzing supply chains beyond a dyadic perspective. This study approaches the problem through the lenses of complex systems and network theories. Drawing on the lessons learned from other systemic-risk-prone systems, e.g. energy and financial networks, both in research and practice, this study analyzes the adequate level of governance to monitor and manage systemic risks in supply chains.
Findings
The authors argue that governance institutions should be mandated to overview and reduce systemic risks in supply chains from the top down, as central bankers do for the financial system. Using firm-level data and tools from network analysis and system dynamics, they could quantify systemic risks, identify risk-prone interconnections in supply chains and design mitigating measures. This top-down approach would complement the bottom-up supply chain management approach and could help insurers design policies for contingent business interruptions.
Originality/value
Instead of looking at supply chains purely from the firms’ angle, the perspective of insurers and governments is brought in to reflect on the governance of risks.

Abstract
Purpose
Many consumer-focused corporate social responsibility (CSR) studies suggest a positive link between the responsibility demonstrated by a company and consumers’ intention to favor the company in their purchases. Yet an analogous causal effect between corporate social and financial performances is not evident. This chapter conceptualizes how social desirability and cynicism contribute to the discrepancy between consumers’ attitudes and their actual purchase behavior, and analyzes why consumer choices indicated in surveys do not consistently convert into actions.
Methodology/approach
We develop a conceptual framework based on hybrid choice modeling to estimate the impact of two new variables, Corporate Social Desirability and Corporate Social Cynicism, on CSR research. The model presented synthesizes research findings from the fields of CSR and psychology with a discrete choice methodology that allows inclusion of psychological aspects as latent variables.
Findings
The goal of the framework is to bridge the gap between choices stated by consumers in CSR surveys and their actual choices by quantifying and extracting the effects of biases that otherwise threaten the validity of such survey results. As the next step, the practical value of the model must be evaluated through empirical research combining a CSR choice study with social desirability and cynicism measurement.
Originality
The framework proposes a novel way of controlling CSR surveys for potential biases created by social desirability and cynicism and enables quantification of this impact, with potential application to other fields where psychological aspects may distort research results. Future empirical evidence based on the framework may also offer new insights into the mechanisms by which the two biases distort findings.

Abstract
Treatment satisfaction of different mental disorders is still poorly understood, but of high clinical interest. Inpatients of a general psychiatric care hospital were asked to fill out questionnaires on satisfaction and clinical variables at admission and discharge. On the basis of an exploratory approach, differences in treatment satisfaction among diagnostic groups were examined by means of one-way analysis of variance. Potential associated clinical and socio-demographic variables were studied using multi/univariate tests. Patients with personality disorders (n=18) showed a significantly lower treatment satisfaction (ZUF-8, Zurich Satisfaction Questionnaire) and a slightly lower improvement of symptoms (CGI, Clinical Global Impression) and global functioning (GAF, Global Assessment of Functioning scale) than that of other diagnostic groups (n=95). Satisfaction in patients with personality disorders correlated much stronger with the symptom improvement and slightly with the functioning level than in patients without personality disorders. Interestingly, in patients with personality disorders psychopharmacological treatment in general (present versus not present) was independent from satisfaction. This exploratory investigation suggests that a lower satisfaction of patients with personality disorders in a general psychiatric hospital is mainly based on a reduced improvement of the symptoms and of the global functioning level.

Abstract
The flexibility of corporations to adapt their strategy to a fast-changing environment can be a major source for competitive advantage and survival. While research mainly focuses on outcomes of this ability, little is known of how to foster it in organizations. Thus, by building on the upper echelons theory, the authors assume that the strategic flexibility of the company depends on the willingness and permission to change of the chief executive officer (CEO). To support the hypotheses, the authors apply the dimensions of commitment to change and work autonomy to the CEO and test for moderation under conditions of technological turbulence. The authors’ results based on medium-sized organizations in Germany show significant effects of both dimensions on strategic flexibility. In particular, under conditions of high technological turbulence, commitment based on loyalty and not on pressure together with autonomy on control and evaluation criteria is best suited to increase strategic flexibility. These insights extend the research literature and provide guidelines for CEOs and their supervisors alike.
