The Relationship Between Sustainable Supply Chain Management, Stakeholder Pressure and Corporate Sustainability Performance
2014
In 2009, Greenpeace launched an aggressive campaign against Nestlé, accusing the organization of driving rainforest deforestation through its palm oil suppliers. The objective was to damage the brand image of Nestlé and, thereby, force the organization to make its supply chain more sustainable. Prominent cases such as these have led to the prevailing view that sustainable supply chain management (SSCM) is primarily reactive and propelled by external pressures. This research, in contrast, assumes that SSCM can contribute positively to the reputation of an organization as a \"good citizen\" and, thereby, counter the impression that external stakeholder pressure is the only driver of SSCM. The study draws on Resource Dependence Theory in analyzing the three competing models of the potential stakeholder, SSCM and the corporate sustainability performance relationship. A dataset of 1,621 organizations allows the statistical comparison of these three models. Findings suggest that stakeholder pressure and SSCM both contribute to an organization's sustainability performance. Thus, supply chain managers will perceive benefits from SSCM other than merely the reduction of risk from reputational damage through stakeholder activism.

2018
Geographic disparities in mortality have been analyzed by place in myriad ways. Although the people who live in a place continuously change, the health characteristics of those places tend to stay the same; they are persistent. Our work analyzes persistence of mortality across various geographic designations and uncovers the wide-ranging disparities in death across the United States. Using 48 years of county-level mortality data, we analyze trends over time and disparities across places using rural-urban distinctions and census-based region and division classifications. Trends in death rates, excess deaths, and rates of mortality improvement are provided. CONTRIBUTION

2015
Recently developed new transducers for ultrasonic transmission, which can be embedded right into concrete, are now used for non-destructive permanent monitoring of concrete. They can be installed during construction or thereafter. Large volumes of concrete can be monitored for changes of material properties by a limited number of transducers. The transducer design, the main properties as well as installation procedures are presented. It is shown that compressional waves with a central frequency of 62 kHz are mainly generated around the transducer’s axis. The transducer can be used as a transmitter or receiver. Application examples demonstrate that the transducers can be used to monitor concrete conditions parameters (stress, temperature, …) as well as damages in an early state or the detection of acoustic events (e.g., crack opening). Besides application in civil engineering our setups can also be used for model studies in geosciences.

Sustainable Supply Chain Management Integration: A Qualitative Analysis of the German Manufacturing Industry
Firms are increasingly integrating sustainability into their supply chain management (SCM) practices. The goal is to achieve sustainable flows of products, services, information and capital to provide maximum value to all corporate stakeholders. Prior research on SCM integration has insufficiently addressed sustainability. The objective of this research is to provide for a coherent and testable model of sustainable supply chain management integration (SSCMI). By drawing on four cases from the German manufacturing industry, we seek to identify the most important factors that enable or impede the integration of sustainability into SCM.

Inhibition of lysyl oxidases synergizes with 5-azacytidine to restore erythropoiesis in myelodysplastic and myeloid malignancies
2023
Limited response rates and frequent relapses during standard of care with hypomethylating agents in myelodysplastic neoplasms (MN) require urgent improvement of this treatment indication. Here, by combining 5-azacytidine (5-AZA) with the pan-lysyl oxidase inhibitor PXS-5505, we demonstrate superior restoration of erythroid differentiation in hematopoietic stem and progenitor cells (HSPCs) of MN patients in 20/31 cases (65%) versus 9/31 cases (29%) treated with 5-AZA alone. This effect requires direct contact of HSPCs with bone marrow stroma components and is dependent on integrin signaling. We further confirm these results in vivo using a bone marrow niche-dependent MN xenograft model in female NSG mice, in which we additionally demonstrate an enforced reduction of dominant clones as well as significant attenuation of disease expansion and normalization of spleen sizes. Overall, these results lay out a strong pre-clinical rationale for efficacy of combination treatment of 5-AZA with PXS-5505 especially for anemic MN.
Hypomethylating agents, such as 5-Azacytidine (5-AZA), are standard of care for patients with myelodysplastic and myeloid malignancies, however response rates are limited and risk of relapses high. Here the authors show that inhibition of lysyl oxidases synergizes with 5-AZA to improve erythropoiesis and reduce disease burden in myelodysplastic neoplasms models.

Do Religious Struggles Mediate the Association Between Neighborhood Disorder and Health in the United States?
2024
Over the past two decades, numerous studies have linked the subjective experience of neighborhood disorder (perceptions of crime, dilapidation and ambient strains) with poorer health. We test whether religious struggles (religious doubts and feeling abandoned or punished by God) mediate this association. Our counterfactual mediation analyses of data from the 2021 Crime, Health, and Politics Survey (CHAPS) (n = 1741) revealed consistent indirect effects of neighborhood disorder through religious struggles for anger, psychological distress, sleep disturbance, poorer self-rated health, and shorter subjective life expectancy. This study contributes to previous work by integrating the study of neighborhood context and religion.

Hearing impairment, the most prevalent sensory deficit, affects more than 466 million people worldwide (WHO). We presently lack causative treatment for the most common form, sensorineural hearing impairment; hearing aids and cochlear implants (CI) remain the only means of hearing restoration. We engaged with CI users to learn about their expectations and their willingness to collaborate with health care professionals on establishing novel therapies. We summarize upcoming CI innovations, gene therapies, and regenerative approaches and evaluate the chances for clinical translation of these novel strategies. We conclude that there remains an unmet medical need for improving hearing restoration and that we are likely to witness the clinical translation of gene therapy and major CI innovations within this decade.
Graphical Abstract
This review summarizes the clinical translation of gene therapy and cochlear implant innovations and discusses if there is an unmet medical need for improving hearing restoration.

Implications of pretend play for Theory of Mind research
2022
Research on the development of Theory of Mind has often focused predominantly on belief attribution, but recently moves have been made to include also other mental states. This includes especially factive mental states like knowledge, where factive Theory of Mind may turn out to be more basic than non-factive Theory of Mind. I argue that children’s early pretend play also carries important implications for Theory of Mind research. Although pretend play does not directly provide evidence of Theory of Mind in young children, it provides evidence of an early ability to handle inconsistent representations, although this ability to access these inconsistent representations may be contingent on external support. Dealing with inconsistent representations is arguably an important component of non-factive Theory of Mind and underlies belief attribution. This carries important implications for debates in Theory of Mind, especially concerning the relationship between factive and non-factive Theory of Mind. I also consider to what extent the findings from pretend play can be extended to support and illuminate the findings from the implicit false belief task.

Post-COVID in healthcare workers and its consequences on quality of life, activities, participation, need for rehabilitation and care experiences: protocol of a cohort study
2024
IntroductionHealthcare workers (HCWs) have been of particular relevance for overcoming the SARS-CoV-2 pandemic. At the same time they have been affected by SARS-CoV-2 infections with above average probability. Around 6.5% of the overall infected persons are likely to develop persistent symptoms resulting from the infection, known as long-COVID or post-COVID syndrome (PCS). The aim of this study is (1) to investigate the prevalence, course and characteristics of PCS in German HCWs, (2) to examine its effects on psychosocial variables, (3) to identify rehabilitation and healthcare needs and (4) to analyse treatment experiences.Methods and analysisIn a cohort study with a randomised selection of participants (N=20 000) from the Employer’s Liability Insurance Association for Health and Welfare Care, the health status of HCWs, who had COVID-19 in their professional context will be examined. There will be two measurement points: baseline (T1) and a 12-month follow-up (T2). The outcome measures are the health status with a particular focus on persistent or newly occurring symptoms after a SARS-CoV-2 infection, health-related quality of life, functional capacity, the subjective need for and utilisation of healthcare services. Pre-existing conditions, the course of the acute infection and sociodemographic factors are considered as predictors. An advisory board made up of affected HCWs supports the study by contributing to the surveys’ contents.Ethics and disseminationThe study has been approved by the Local Ethics Committee of the Center for Psychosocial Medicine at the University Hospital Hamburg-Eppendorf (LPEK-0518). For dissemination, the results will be published in peer-reviewed journals, presented at conferences and communicated to relevant stakeholders in general and rehabilitation medicine.Trail registration number https://drks.de/search/de/trial/DRKS00029314
