Scholars widely refer to the multi-level perspective (MLP) in the analysis of those transitions. The fast pace of articles covering AFS transitions, the evolving research on spaces between the three levels, and the consisting unclear conceptualization of MLP levels call for a systematic update on literature utilizing MLP in AFS articles covering ST. As a basis for reporting, this systematic literature review uses the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). The search was conducted on the database Scopus encompassing the period from 2018 to 2022. After the selection procedure, 58 articles were included in the review. We extracted data based on a combination of a concept-driven and data-driven coding scheme. Qualitative research approaches outweigh and interrelated activities within the AFS are being analyzed, predominantly in the agricultural sectors. The focus lays on ongoing transitions. The concept of sustainability and its direction is considered as given (e.g., through the case lens), without further elaborations. The niche constitutes the most prominent object of study and scholars refer to rather socially innovative activities than technological innovations, providing distinct views on radicality and strategies to breakthrough. A space between niche and regime is being presented, with slightly distinct conceptualisations. Actors from both levels collaborate and exert transformative power. The regime is presented as static but also more vividly evolving views on the regime are demonstrated. The landscape receives the least attention and the focus lays on immaterial characteristics. Combinations of MLP with other frameworks have proven useful, for instance, regarding elaborations on the agency on the landscape level. Generally, an unclear conceptualization of regime and landscape persists, lacking a theoretical elaboration. Further research applying MLP should aim for a deeper examination of its theoretical construct, especially in terms of regime and landscape. More quantitative or mixed-methods research could supplement the current dominating qualitative approaches by testing and validating qualitatively constructed theories and phenomena.}, language = {en} } @article{HeidtFobkerNewportetal.2023, author = {Heidt, C. and Fobker, M. and Newport, M. and Feldmann, R. and Fischer, T. and Marquardt, T.}, title = {Beta-Hydroxybutyrate (BHB), Glucose, Insulin, Octanoate (C8), and Decanoate (C10) Responses to a Medium-Chain Triglyceride (MCT) Oil with and without Glucose: A Single-Center Study in Healthy Adults}, series = {Nutrients}, volume = {15}, journal = {Nutrients}, number = {5}, doi = {10.25974/fhms-17085}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:836-opus-170851}, pages = {1 -- 17}, year = {2023}, language = {en} } @article{JohnFischerOchetal.2019, author = {John, H. and Fischer, T. and Och, U. and Baumeister, A. and Wahrburg, U.}, title = {Additional costs of a low-protein diet in children and adolescents with phenylketonuria}, series = {Ern{\"a}hrungs Umschau}, volume = {66}, journal = {Ern{\"a}hrungs Umschau}, number = {11}, issn = {0174-0008}, doi = {10.4455/eu.2019.036}, pages = {221 -- 227}, year = {2019}, language = {en} } @article{FischerElpersOchetal.2019, author = {Fischer, T. and Elpers, C. and Och, U. and Fobker, M. and Marquardt, T.}, title = {Ketone body therapy with D/L-ß-hydroxybutyric acid solution in severe MADD, Molecular Genetics and Metabolism Reports}, series = {Molecular Genetics and Metabolism Reports}, journal = {Molecular Genetics and Metabolism Reports}, doi = {10.25974/fhms-17113}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:836-opus-171133}, pages = {1 -- 5}, year = {2019}, language = {en} } @article{OchFischerMarquardt2019, author = {Och, U. and Fischer, T. and Marquardt, T.}, title = {Dietary carbohydrate modification in Niemann-Pick Type C.

We evaluated changes in total costs, comprising direct and indirect costs, due to a 24-month non-randomized, controlled lifestyle intervention trial with six measurement time points aiming to improve the risk profile for NCDs. Overall, 187 individuals from the general population aged ≥18 years were assigned to either the intervention group (IG; n = 112), receiving a 10-week intensive lifestyle intervention focusing on a healthy, plant-based diet; physical activity; stress management; and community support, followed by a 22-month follow-up phase including monthly seminars, or a control group (CG; n = 75) without intervention. The complete data sets of 118 participants (IG: n = 79; CG: n = 39) were analyzed. At baseline, total costs per person amounted to 67.80 ± 69.17 EUR in the IG and 48.73 ± 54.41 EUR in the CG per week. The reduction in total costs was significantly greater in the IG compared to the CG after 10 weeks (p = 0.012) and 6 months (p = 0.004), whereas direct costs differed significantly after 10 weeks (p = 0.017), 6 months (p = 0.041) and 12 months (p = 0.012) between the groups.

Survey measures were taken from a random sample of 72 CEOs of German family firms and 245 members of their TMTs.

Mergers \& acquisitions (M\&As) can be an effective way to expand into new markets or business opportunities. Yet, a considerable number of failed M\&As can be attributed to disregarded human resource (HR) concerns. In particular, an organization's leadership tends to hail the advantages of a merger or acquisition during the early stages, raising employees' expectations (honeymoon effect). Many documented failures in such corporate transactions indicate organizational members' declining satisfaction following a deal (hangover effect). Design/methodology/approach. Drawing on in-depth interviews with senior M\&A experts at a global big-four accountancy firm and focus group sessions with their respective clients, this study investigates in two cases the interplay between HR issues and M\&A transactions and infers effective risk management actions. Findings. A honeymoon hangover after a transaction may appear in organizations if HR issues are neglected. Study results provide notable implications for HR departments and HR professionals facing a merger or acquisition. These implications include (1) focusing on HR risks, (2) involving HR executives to manage the HR due diligence efforts, (3) setting up transition teams that communicate well, (4) creating policies for learning and knowledge sharing, (5) developing new competencies for the NewCo, (6) being sensitive to cultural differences and (7) considering legal aspects. Originality/value. Although M\&As have been much researched, relatively little has been written on practical managerial adaptation from a human resource perspective and its implications for organizational learning. This article helps address this imbalance by providing a people-oriented approach for effectively managing M\&As from beginning to integration. Research limitations/ implications. The two transactions studied revealed patterns that are important for successful change. However, we should not underestimate the individual perspective in M\&As. Further studies with interview data directly from stakeholders are important to analyze further the relationships between HR due diligence, organizational learning, effective knowledge transfer, and culture. Due to our research approach, we cannot claim that the results can be generalizable to all major M\&As. Further research is needed to measure the impact of the HR Due Diligence aspects outlined on M\&A success.}, language = {en} } @article{NeffeWilderomLattuch2024, author = {Neffe, C. and Wilderom, C.P.M. and Lattuch, F.}, title = {Family firm performance through transformational CEO leadership and familiness-related team forces}, series = {Leadership \& Organization Development Journal}, volume = {45}, journal = {Leadership \& Organization Development Journal}, number = {im Erscheinen}, issn = {0143-7739}, pages = {. -- ..}, year = {2024}, abstract = {Purpose. The purpose of this study is to test the role of familiness-related team forces induced by the CEO of family firms. In particular, we report on the effects of the transformational leadership style of CEOs on their respective top-management team (TMT) and firm performance when viewed through a familiness lens. Design/methodology/approach. Survey measures were taken from a snowballed sample of 72 CEOs of German family firms as well as from 245 members of their TMTs. We tested the aggregated firm-level data with objective performance indicators of the firms they led. Findings. Support was obtained for the three hypothesized team-force mediations and the four-path mediation model. The relationship between CEO's transformational style and high family-firm performance is found to be serially mediated by TMT cohesion, behavioral integration and efficacy. Together, these three types of collective forces are assumed to be the familiness effect of a family-member CEO with a transformational leadership style. Originality.
