Currently, the treatment of musicians is an interprofessional approach. Playing-related health complaints may impact the performance of a musician. In Germany, a medical consulting hour for musicians exists, but those for athletes in sports medicine are not so common. The diagnosing and treatment procedure within the physiotherapy consultation for musicians follows a specific concept-b and requires knowledge of instruments and musician-specific complaints. Based on the consulting hour in a clinic in Osnabrueck, 614 case reports were part of this sample, of which 558 data sets were complete. The focus of the analysis is the instrument and the primary complaint. Also, the type of therapy is characterized, and the amount is calculated. Primary complaints of musicians, in general, are found most frequently in the spine and upper extremity. Musician complaints are different between instruments. Instrumentalists have a significantly higher chance to suffer from a primary complaint in the area of the upper extremity. Furthermore, the groups without an instrument (e.g., singing or dancing) are developing complaints in the anatomical area which they primarily use. Therefore, these types of therapy were used: physiotherapy, manual therapy, and osteopathy with an average of 5.9 treatment units. This study underpinned the importance of musician-specific physiotherapy as a profession to treat musicians. Also, an interdisciplinary approach is necessary to treat all aspects of complaints.

This study reported the impact of electron beam (e-beam) treatment on microbiota and mycotoxins naturally present in red pepper powder and physicochemical quality changes. Treatment at 6 kGy indicated significant (p < 0.05) decontamination of yeasts and molds by 3.0 and 4.4 log CFU/g, respectively. A reduction of 4.5 log CFU/g of total plate counts (TPC) was observed at 10 kGy for 23 s. Fungal inactivation followed first-order kinetics while TPC better fitted with Gompertz function (R2 = 0.9912). E-beam treatment was not efficient for the degradation of aflatoxins but indirectly controlled their production by inactivation of mycotoxigenic molds. Indeed, reduction of 25% ochratoxin A was recorded at 30 kGy retaining >85% of total phenols, carotenoids and antioxidants activity. Moreover, treatment impact on total color difference (ΔE*) indicated ‘slight differences’. Overall, e-beam treatments up to 10 kGy were efficient in decontaminating the natural microbiota without detrimental effects on the physicochemical qualities of red pepper powder.
Red pepper (Capsicum annuum L.) is one of the major spices consumed globally, recognized for its aroma and nutrient properties, and it has a major economic value for high producing countries. However, characterization of its techno-functional properties and in-depth understanding of oxidative stability is needed to produce food of high quality and stability. Thus, this work focused on the chemical, functional, thermal, oxidative stability and rheological properties of red pepper powder and paste. Experiment was designed in a Completely Randomized Design (CRD) fashion. The red pepper powder contained 14.50 g/100 g, 44.00 g/100 g and 7.57 g/100 g of crude fat, crude fiber and ash, respectively. The concentration of total phenols, carotenoids and antioxidants activity of the powder were 1.04 g GAE/100 g, 374 mg βc/100 g and 38.61 μmol TE/g, respectively. Functional properties showed lower bulk density (395.1 kg/m3) and higher tapped density (583.4 kg/m3) indicating the higher compressibility of the powder. In contrast, Hausner ratio (1.48), Carr’s index (32%) and angle of repose (45°) indicated poor flowability of the powder. Particle size distribution also indicated that the volume weighted mean values D[4,3] of the powder and paste were 262.20 and 201.46, respectively. Emulsifying capacity of the powder was 47.5%. Oil and water absorption capacities varied from 1.41 to 1.73 and 0.86 to 2.29 g/g of initial weight, respectively. Higher glass transition temperature was observed for the powder (62.54°C) than the paste (45.64°C). The induction period indicated that red pepper was more stable against oxidation in powder (5.2 h) than in the paste form (3.2 h). Rheological analysis revealed that the paste exhibited shear-thinning behavior. Overall, understanding of the properties of red pepper could contribute to enhance quality.
The study aimed for the analysis of the impact of pulsed electric field (PEF) pre-treatment on convection (CD) and microwave (MW-CD) assisted air drying. Drying kinetics acceleration and retention of bioactive compounds of PEF pre-treated carrots and apples has been demonstrated. Moreover, the direct and indirect environmental energy impacts of CD and MW-CD technologies with consideration of bioactive compounds preservation has been evaluated. PEF assisted CD and MW-CD demonstrated lower energy use, especially for indirect energy consumption, in the case of carotenoids preservation in dried carrots.

Consumer Acceptance and Market Potential of Iodine-Biofortified Fruit and Vegetables in Germany
(2021)
Biofortification of food crops with iodine is a novel approach to preventing iodine deficiency in humans. The present study analyses the consumer target groups and the market potential of iodine-biofortified fruit and vegetables in Germany. For this purpose, an online survey of 1016 German fruit and vegetable consumers was conducted to investigate the acceptance of different product categories as well as relevant criteria for the market launch. The results show that io-dine-biofortified fruit and vegetables are particularly attractive to consumers who purchase at farmers’ markets, organic food shops, and farm stores. Out of this group, 39% of consumers rate such iodine-rich foods as very appealing. They attach importance to food that naturally contains iodine and prefer produce from integrated domestic cultivation. With their focus on sustainability and naturalness, this group of consumers clearly differs from typical users of dietary supplements, who are primarily concerned with health benefits. However, overall about 85% of respondents would prefer biofortified fruits and vegetables to supplements to improve their iodine supply. The greatest market potential for iodine-biofortified fruit and vegetables is to be expected in super-markets, as this is the preferred food shopping location for most consumers. A total of 28% of those who buy here rate the biofortified foods presented as very appealing. Nevertheless, a successful market launch requires that the benefits of the new products are communicated according to the potential consumer group needs.
Background:
Contact tracing apps are potentially useful tools for supporting national COVID-19 containment strategies. Various national apps with different technical design features have been commissioned and issued by governments worldwide.
Objective:
Our goal was to develop and propose an item set that was suitable for describing and monitoring nationally issued COVID-19 contact tracing apps. This item set could provide a framework for describing the key technical features of such apps and monitoring their use based on widely available information.
Methods:
We used an open-source intelligence approach (OSINT) to access a multitude of publicly available sources and collect data and information regarding the development and use of contact tracing apps in different countries over several months (from June 2020 to January 2021). The collected documents were then iteratively analyzed via content analysis methods. During this process, an initial set of subject areas were refined into categories for evaluation (ie, coherent topics), which were then examined for individual features. These features were paraphrased as items in the form of questions and applied to information materials from a sample of countries (ie, Brazil, China, Finland, France, Germany, Italy, Singapore, South Korea, Spain, and the United Kingdom [England and Wales]). This sample was purposefully selected; our intention was to include the apps of different countries from around the world and to propose a valid item set that can be relatively easily applied by using an OSINT approach.
Results:
Our OSINT approach and subsequent analysis of the collected documents resulted in the definition of the following five main categories and associated subcategories: (1) background information (open-source code, public information, and collaborators); (2) purpose and workflow (secondary data use and warning process design); (3) technical information (protocol, tracing technology, exposure notification system, and interoperability); (4) privacy protection (the entity of trust and anonymity); and (5) availability and use (release date and the number of downloads). Based on this structure, a set of items that constituted the evaluation framework were specified. The application of these items to the 10 selected countries revealed differences, especially with regard to the centralization of the entity of trust and the overall transparency of the apps’ technical makeup.
Conclusions:
We provide a set of criteria for monitoring and evaluating COVID-19 tracing apps that can be easily applied to publicly issued information. The application of these criteria might help governments to identify design features that promote the successful, widespread adoption of COVID-19 tracing apps among target populations and across national boundaries.
Hintergrund: Die Gesundheitskompetenz (GK) gilt als bedeutender Prädiktor für die Gesundheit. In der deutschen Bevölkerung ist sie nur unzureichend ausgeprägt. Die vorliegende Untersuchung geht der Frage nach, welchen Beitrag die Gesundheitsprofessionen zur Förderung der GK leisten können.
Ziel: In dieser Arbeit werden das Verständnis der Gesundheitsprofessionen von GK sowie fördernde und hemmende Faktoren bei ihrer Vermittlung untersucht.
Methode: Die Untersuchung wurde als qualitative Studie im Design der Grounded Theory durchgeführt. Es wurden 16 halbstrukturierte, leitfadengestützte Interviews geführt.
Ergebnis: Die Ergebnisse verdeutlichen das Verständnis der Gesundheitsprofessionen von GK als Empowerment zu mehr Gesundheit. Dies soll mit einem Wechsel zur holistischen Perspektive auf die Menschen und der Verortung der Verantwortung für die Stärkung von GK in Politik und Gesellschaft gelingen. Voraussetzung dafür ist die vermehrte Aufmerksamkeit des Themas in Theorie und Praxis.
Schlussfolgerung: Aus den Ergebnissen dieser Untersuchung lassen sich Unterstützungsmaßnahmen für die Gesundheitsprofessionen bei ihrer Aufgabe, GK zu vermitteln, ableiten. Für ihre Mitarbeit muss intensiv geworben werden, zudem sind insbesondere politische Maßnahmen bedeutend, die auf ein höheres gesellschaftliches Engagement hinwirken.
Acute post-operative delirium (POD) and long-term post-operative cognitive dysfunction (POCD) are frequent and associated with increased mortality, dependency on care giving and institutionalization rates. The POCD-related cost burden on the German long-term care insurance provides an indication for the savings potential from risk-adapted treatment schemes. Comprehensive estimates have not been assessed or published so far.
A model-based cost-analysis was designed to estimate POCD-related costs in the long-term care insurance. Comprehensive analysis of inpatient operations and procedures (OPS-codes) served as the base for case number calculations, which were then used as input to the actual cost model. POCD-incidence rates were obtained from the BioCog study. Various sensitivity analyses were performed to assess uncertainty of the model results.
Total POCD related annual costs in the German long-term care insurance account for approximately 1.6 billion EUR according to the base case of our analysis. Total annual costs for all POCD cases depend on surgery numbers, incidence rates, other assumptions, and uncertain input parameters.
The financial burden to the long-term care insurance is substantial, even in a conservative scenario of the cost model. Variability of results stems from uncertain assumptions, POCD-incidence rates and from uncertain patient numbers who are undergoing surgery and are therefore at risk to develop POCD.
Chitin is an abundant waste product from shrimp and mushroom industries and as such, an appropriate secondary feedstock for biotechnological processes. However, chitin is a crystalline substrate embedded in complex biological matrices, and, therefore, difficult to utilize, requiring an equally complex chitinolytic machinery. Following a bottom-up approach, we here describe the step-wise development of a mutualistic, non-competitive consortium in which a lysine-auxotrophic Escherichia coli substrate converter cleaves the chitin monomer N-acetylglucosamine (GlcNAc) into glucosamine (GlcN) and acetate, but uses only acetate while leaving GlcN for growth of the lysine-secreting Corynebacterium glutamicum producer strain. We first engineered the substrate converter strain for growth on acetate but not GlcN, and the producer strain for growth on GlcN but not acetate. Growth of the two strains in co-culture in the presence of a mixture of GlcN and acetate was stabilized through lysine cross-feeding. Addition of recombinant chitinase to cleave chitin into GlcNAc2, chitin deacetylase to convert GlcNAc2 into GlcN2 and acetate, and glucosaminidase to cleave GlcN2 into GlcN supported growth of the two strains in co-culture in the presence of colloidal chitin as sole carbon source. Substrate converter strains secreting a chitinase or a β-1,4-glucosaminidase degraded chitin to GlcNAc2 or GlcN2 to GlcN, respectively, but required glucose for growth. In contrast, by cleaving GlcNAc into GlcN and acetate, a chitin deacetylase-expressing substrate converter enabled growth of the producer strain in co-culture with GlcNAc as sole carbon source, providing proof-of-principle for a fully integrated co-culture for the biotechnological utilization of chitin.
Seit Jahren schon hat Sarah J. das Gefühl, immer müder und weniger belastbar zu werden. Selbst im Garten schafft sie kaum noch was. Liegt es wirklich nur am Verlust ihres Mannes? Zunehmende Zahn- und Kieferschmerzen und Schmerzen im Thorax führen sie zur Physiotherapie. Dort rückt eine andere Vermutung in den Fokus.
The management of patients experiencing chronic orofacial pain is a great challenge, due to the complexity of chronic pain itself, combined with an increased peripheral sensitization in the craniofacial itself. Therefore, patients with orofacial pain may present a clear distortion of the somatorepresentation after some time. In this review, the authors develop a neurophysiological explanation of orofacial distortion, as well as propose assessment and treatment options, based on scarcely available scientific evidence and their own clinical experience. The assessments of facial somatosensory, cognitive-affective and motor dysfunctions are crucial to establish the most accurate treatment; the assessment tools are described in the article. Two-point discrimination, laterality recognition and emotion recognition are altered in patients with orofacial pain. Other sensorimotor assessment tools, such as motor acuity and auditory acuity, are also explained. Finally, the authors review their treatment proposals, based on the integration of brain training techniques and biobehavioral interventions. Somatosensory reintegration (tactile acuity training), facial emotion recognition, movement representation techniques, orofacial motor training and therapeutic patient education are explained in detail, and this may challenge new directions in rehabilitation and research.
BACKGROUND: The Craniofacial Pain and Disability Inventory (CF-PDI) is a cross-culturally adapted instrument designed from a biopsychosocial perspective to measure pain, disability, and function in orofacial head and neck pain with shown psychometric properties; however, the German cross-cultural adaption is lacking.
OBJECTIVES: To carry out a transcultural translation of CF-PDI into German and assess its psychometric properties in patients with painful temporomandibular disorders (TMD) with respect to construct and clinical validity, internal consistency and reproducibility.
STUDY DESIGN: Multicenter, prospective, cross-sectional design.
SETTING: Patients (n = 398) were recruited from dental and physical therapy clinics in middle and south Germany.
METHODS: Structural validity was assessed using exploratory factor analysis (EFA) and confirmatory factor analysis (CFA). We investigated know-group validity by means of the scale’s potential to discriminate between affected and unaffected subjects. Multiple linear regression analysis was used to estimate convergent validity. We tested test-retest reliability by the intraclass correlation coefficient and the Internal consistency by Cronbach’s alpha, or each dimension separately, and the total score. Multiple linear regression analysis was used to estimate convergent validity.
RESULTS: Two hundred forty-six heterogeneous chronic craniofacial pain patients and 152 patients without complaints were recruited from the middle and south of Germany. The German version CF-PDI-G presents 21 items, 4 factors, and adequate psychometric properties. The test-retest reliability and internal consistency of the CF-PDI-G were both excellent for the entire instrument and also for all sub-scales (intraclass correlation coefficient [ICC] > 0.90) except for the comorbidities and interference with work which was acceptable (ICC = 0.69). Standard error of the measurement (SEM) and minimal detectable change values are sufficiently low. Assessment of clinical validity shows good potential of discrimination and classification into categories “no,” “mild,” “moderate,” and “severe.” The multiple linear regression model showed a strong association between neck disability index, Visual Analog Scale, and anamnestic questionnaire (supporting the scale’s convergent validity).
LIMITATIONS: Our sample has a higher prevalence of women and the sample was not recruited consecutively, which may lead to a biased estimation of psychometric properties.
CONCLUSIONS: The CF-PDI-G represents valid and reliable instrument to assess pain and disability in patients with orofacial pain and headache suitable for research and clinical practice.
Bruxismus ist keine Krankheit, sondern ein Sammelbegriff für Parafunktionen wie Zähnepressen oder Knirschen. Um Begleitsymptome des Bruxismus zu beeinflussen, ist eine Untersuchung des orofazialen und kraniozervikalen Systems sinnvoll. Die gefundenen auffälligen Zeichen leiten die Therapeuten in der muskuloskelettalen Therapie, die aus Hands-on und -off-Techniken besteht.
Am 16.12.2020 hat das Bundeskabinett den Entwurf eines Gesetzes zur Stärkung der Finanzmarktintegrität beschlossen. Dies ist eine Reaktion auf den Bilanzskandal beim ehemaligen DAX-Konzern Wirecard. Mit dem Gesetzentwurf werden eine Reduzierung von Schwachstellen bei der Kontrolle von Bilanzen, eine Stärkung der Unabhängigkeit der Abschlussprüfer sowie eine Verbesserung von internen Kontrollen in Unternehmen angestrebt. So sollen der Finanzplatz Deutschland an Integrität sowie Attraktivität gewinnen und verlorenes Vertrauen wieder aufgebaut werden. Der nachfolgende Beitrag beschäftigt sich mit der Entstehung und ausgewählten Inhalten des Gesetzentwurfs und gibt anschließend einen Überblick über die aktuelle Diskussion der Reformpläne in der Literatur.
In this experimental work, the quasi static and fatigue properties of a 40 wt.% long carbon fiber reinforced partially aromatic polyamide (Grivory GCL-4H) were investigated. For this purpose, microstructural parameter variations in the form of different thicknesses and different removal directions from injectionmolded plates were evaluated. Mechanical properties decreased by increasing misalignment away from the melt flow direction. By changing the specimen thickness, no change in the general fiber distribution pattern transversal and normal to the axis of melt flow was observed. It has shown that with increasing specimen thickness the quasi static properties along the melt flow direction decreased and vice versa resulting in superior properties normal to the melt flow axis. At around 5 mm, an intersection suggests quasi-isotropic behavior. In addition, the fatigue strength of the material was significantly higher in the flow direction than normal to the flow direction. No change in fatigue life was observed while changing specimen thickness. The Basquin equation seems to describe the effect of stress amplitude on the fatigue strength of this composite. Scanning electron microscopy was used to investigate fracture surfaces of tested specimens. Results show that mechanical properties and morphological structures depend highly on fiber orientation.
Professionalization in low-threshold drug aid : between managerialism and practitioner knowledge
(2021)
Purpose
This paper aims to investigate the strategic consequences of manufacturing location decisions, with a focus on understanding the link between collocating manufacturing with other value chain activities, via reshoring or retaining and organizational agility.
Design/methodology/approach
The paper uses qualitative data from 115 interviews with executives from UK high value manufacturing companies to explore the recent phenomenon of reshoring and the strategic effects of manufacturing location.
Findings
The location of manufacturing is operationally and strategically important for multinational companies. The spatial dispersion of manufacturing is determined by firm-specific and external factors, both of which are subject to constant change. The analysis shows that concentrating on manufacturing in their home countries enables firms to increase organizational agility and stimulate innovation. Better integration with and more extensive collaboration between related value chain activities, such as research and development, sales and marketing, leads to higher flexibility, speed and responsiveness to customer requirements. However, under certain conditions, firms also continue to benefit from the known advantages of offshoring.
Originality/value
This research sheds light on possible strategic downsides of global value chains, characterized by dispersed activities and intermitted processes. The results provide evidence that retaining manufacturing or bringing back manufacturing operations to a company’s home country can increase organizational flexibility, speed, adaptability, innovativeness and responsiveness to customer requirements. As these capabilities are critical for long-term survival, especially in dynamic environments, firms need to review their global factory configurations and determine whether the short-term advantages of foreign locations continue to justify offshoring practices.
Quantitative Umweltbewertungen sind von entscheidender Bedeutung, wenn es darum geht, effektiv auf nachhaltige Produktions- und Verbrauchsmuster hinzuarbeiten. In den letzten Jahrzehnten haben sich Lebenszyklusanalysen (LCA) als praktikables Mittel zur Messung der Umweltauswirkungen von Produkten entlang der Lieferkette etabliert. In Bezug auf Nutzer- und Konsummuster wurden jedoch methodische Schwächen festgestellt, und es wurden mehrere Versuche unternommen, Ökobilanzen entsprechend zu verbessern, beispielsweise durch Einbeziehung von Effekten höherer Ordnung und verhaltenswissenschaftlicher Unterstützung. In einer Diskussion solcher Ansätze zeigen wir, dass den Konzepten des Verbrauchs keine explizite Aufmerksamkeit geschenkt wurde, was häufig zu produktzentrierten Bewertungen führt. Wir führen Theorien sozialer Praktiken ein, um Konsummuster für LCA zugänglich zu machen. Soziale Praktiken sind routinierte Handlungen, die aus miteinander verbundenen Elementen (Materialien, Kompetenzen und Bedeutungen) bestehen, die sie als eine Einheit denkbar machen (z. B. Kochen). Da die meisten sozialen Praktiken eine Art von Verbrauch (Material, Energie, Luft) beinhalten, konnten wir einen Rahmen entwickeln, der soziale Praktiken mit der Ökobilanz verbindet. Der vorgeschlagene Rahmen bietet eine neue Perspektive für quantitative Umweltbewertungen, indem er den Schwerpunkt von Produkten oder Nutzern auf soziale Praktiken verlagert. Dementsprechend sehen wir die Chance darin, die reduktionistische Sichtweise zu überwinden, dass Menschen nur Nutzer von Produkten sind, und sie stattdessen als Praktiker in sozialen Praktiken zu sehen. Dieser Wandel könnte neue Methoden der interdisziplinären Konsumforschung ermöglichen, die beabsichtigte Sozialwissenschaften und wirkungsorientierte Bewertungen einbeziehen. Allerdings bedarf der Rahmen einer weiteren Überarbeitung und vor allem einer empirischen Validierung.
Objective: To understand the meaning of the Learning Incubator as a teaching and learning technology in the nursing area.
Method: Qualitative research, supported by grounded theory. Data was collected from March to November 2019, through interviews with guiding questions and hypotheses directed at two different groups. The analysis was done by comparative data analysis and included open, axial and integrated coding, as proposed by the method. The theoretical sample included 23 participants, which were nurses, technicians, and nursing students.
Results: The delimitation of the categories converged in the phenomenon (Re)signifying knowledge and practices in the Learning Incubator. Guided by the paradigmatic model, the categories were named according to the three following components: Condition: Recognizing that the being and the professional practice are inextricable; Action/interaction: Revisiting professional practices that are repetitive and mechanic; Consequence: Referring to the reflections and knowledge constructed in the Learning Incubator.
Conclusion: The Learning Incubator, as seen by the study participants, is not limited to the Incubator meetings or the themes addressed in it. Beyond a welcoming physical space, the Incubator expands itself and becomes a tool that promotes self-reflection and self-assessment of professional behaviors and attitudes.
Objective:
to carry out a theoretical reflection on the Nursing Now Campaign and the experience of the unexpected irruptions facing the pandemic period.
Method:
a theoretical-reflective study, supported by the theoretical framework of complexity thinking. It aims at understanding the dialogic between the notions of order, disorder and organization, which translate the transition from simplification to complexity of the pandemic phenomenon and its relation to the theme of Nursing Now and Nursing in the future.
Results:
the universe of phenomena is simultaneously composed of order, disorder and organization. Reasserting the central role of Nursing in the health team, facing the irruptions and uncertainties caused by the current pandemic, implies the ability to dialog with disorder and raise a new and more complex global (re)organization of the being and doing Nursing.
Conclusion:
in addition to answers, theoretical reflection raises new questions and irruptions. The inseparability between the notions of order and disorder in the evolutionary dynamics of the Nursing system is conceived and the promotion of even more complex levels of organization, management and Nursing assistance to achieve universal access to health is advocated.
Objective:
To understand the meaning of entrepreneurial nursing care as inducer of healthy practices in vulnerable communities.
Method:
Grounded theory, whose data collection took place between March and December 2019, from interviews with 19 participants from the central region of Rio Grande do Sul, Brazil and comparative data analysis.
Results:
The phenomenon was delimited: Experiencing small/big transformations in the invisibility of everyday life in promoting healthy practices in vulnerable communities. Conducted by the paradigmatic model, the categories were named based on the components: Condition: Making choices and negotiating non-negotiable exchanges; Action/interaction: Motivating oneself to maintain basic human needs; Consequence: Broadening perspectives and transcending personal and collective boundaries.
Conclusion:
Entrepreneurial nursing care as inducer of healthy practices in vulnerable communities is not reduced to a scientific theory or to the linear and decontextualized apprehension of healthy living, but extends to reach small/big transformations that occur in the invisibility of everyday life.
Are natural floods accelerators for streambank vegetationdevelopment in floodplain restoration?
(2021)
Riverbanks are very dynamic habitats for riparian vegetation strongly influenced byfluvial and geomorphic processes. This habitat type was severely reduced in the pastby river straightening and bank stabilisation. Restoration and establishment of newfloodplain streams promote this habitat, but a directed succession to later stages wasobserved many times. Our study aimed to analyse whether the often observeddirected succession of the streambank vegetation after restoration implementationcould be reversed by a natural flood along a newly created floodplain stream. Weinvestigated the effects of a natural flood in 2013 and different prerestorationconditions on species development in the riparian zone. Vegetation was studiedalong 12 transects in four different sections from 2011 to 2014. Species composi-tion differed strongly between the sections. Species richness was lowest in a newlydug steep section with high morphological dynamics and highest on wider flatstreambanks. Changes during the years reflecting different hydrological eventsvaried between sections. The high natural flood in 2013 reduced the cover of theherb layer and increased bare ground, which led in most sections to a loss of non-target species. Total target species richness did not change due to the natural flood,while target species showed a high turnover rate. In the following year, however,the flood‐induced development of species composition, in general, was reversed.Natural floods changed abiotic and biotic conditions along the streambank, but theydid not accelerate ecological restoration towards predefined target ecosystems.However, they were necessary to preserve the needed dynamic vegetation changesand species turnover to hinder the succession to later stages dominated by a fewspecies. Our study shows that riparian vegetation near the streambank can bemonitored most effectively in cross‐profile transects, both in the long‐term andevent‐related.
Der Konsumbereich „Ernährung“ verantwortet in Deutschland rund 15 % der Treibhausgasemissionen (THG). Aufgrund der hohen Nachfrage hat die Außer-Haus-Verpflegung eine starke Hebelwirkung, um eine klimaeffiziente Ernährung voranzutreiben – so auch Schulküchen. Aktuell sind der Verpflegung jedes Schulkindes, welches ganzjährig an der Mittagsverpflegung teilnimmt, pro Jahr etwa 264 kg THG-Emissionen zuzuschreiben.
Im Projekt KEEKS „Klima- und energieeffiziente Küche in Schulen” wurden deshalb in 22 Schulküchen von Ganztagsschulen mit täglich insgesamt 5 000 Mittagessen der Status Quo ermittelt. Dies geschah mittels Energiemessungen, Analyse von Ausstattung, Technik und Prozessen der Küchen sowie leitfadengestützten Interviews mit den Küchenleitungen. Treibhausgasemissionen von Menüs und Küchenprozessen wurden bilanziert, Einsparpotenziale identifiziert sowie Handlungsempfehlungen entwickelt und erprobt. Die effektivsten Maßnahmen – die Reduktion und Substitution von Fleisch und Fleischprodukten sowie der Aufbau eines effizienten Abfallmanagements – sparen rund 10 % des Treibhausgasausstoßes einer Schulküche ein. Die erarbeiteten Handlungsempfehlungen können Küchenpersonal dabei unterstützen, eine klimafreundliche, kindgerechte, gesunde und bezahlbare Schulküche zu gestalten.
Chronic illness can have a profound impact on couples’ relationships. In dealing with relational changes, new constructions and forms of relationships may arise. In the context of a larger grounded theory study on relational processes and practices in couples faced with chronic illness, this article focuses on concurrent relationships as an alternative form of relationship construction which embodies an additional relationship existing parallel to that of the couple confronted with chronic illness. Based on qualitative interviews with a subsample of five persons within the larger study, conditions for the development and characteristics of concurrent relationships are presented. From an individual and shared life questioned by chronic illness, concurrent relationships are formed in the attempt to be able to live on together in a new partner relationship and a continued care relationship. This can lead to new constructions of relationships, family life, and social relations in everyday life.
Green roofs are known to mitigate the negative effects of urban consolidation by offering diverse ecosystem functions compared to non-vegetated roofs. However, the support for native biodiversity might be improved by using native plant species. In a mesocosm experiment, we studied the suitability of three commercial green-roof growth substrates for the establishment of 27 native plant species from dry sandy grasslands of northwestern Germany over the course of four years. The substrates were mineral-based, but differed in the layering of organic matter. Total establishment rates reached 44–59% in Year 4, indicating the general suitability of the substrates. During the first weeks after seeding, with light irrigation, the vascular plant cover was greater in the similar substrates Zincolit® Plus (Z) and Zincolit® Plus-Leicht (ZL) with their compost-based organic mulch layers than in the substrate Sedumteppich (ST) with its organic matter evenly admixed with the mineral aggregates. In Years 2 and 3, however, the vascular plant cover was greater in the ST substrate, likely due to the better availability of water and nutrients from the organic matter compared to the dry surface-mulch layer variants Z and ZL. After severe drought events, the decline in plant cover was more pronounced in the ST substrate, likely representing a trade-off between lush growth and a susceptibility to drought. An indicator-species analysis revealed differences in species composition between the ST and Z/ZL substrates. Annual plant species were indicators of the ST substrate. Perennials, such as Thymus pulegioides and Achillea millefolium, were typical of the Z and ZL substrates. In addition to the general suitability of the tested standard substrates for target species establishment, the study indicated that a combination of different layers of substrate components resulted in different vegetation patterns that may have a positive effect on green-roof biodiversity.
Die steigenden Anforderungen im Wettbewerb, die Zahl der Innovationen und die digitale Transformation haben in den letzten Jahren zu einem komplexeren, dynamischeren und unsichereren Unternehmensumfeld - Stichwort VUKA-Welt (Steinberg & Pfarr, 2019) - geführt, welches die zunehmende Herausforderung von ständigen Veränderungsprozessen in Unternehmen mit sich gebracht hat (Steinberg & Pfarr, 2019; Buchholz & Knorre, 2019; Güttel & Link, 2014). Durch diesen Zusammenhang wurde auch eine steigende Anzahl an virtuellen Teams bedingt (Ozga & Stelmaszvzyk, 2016; de Pillis & Furumo, 2007). Diverse Gründe wie z.B. der Fachkräftemangel oder eine mögliche Kostenreduktion durch weniger Reisen (Levasseur, 2012) führen dazu, dass virtuelle Teams für Unternehmen auch in Zukunft immer attraktiver werden (Nydegger & Nydegger, 2010; Levasseur, 2012). Auch wenn die Forschungsbeiträge von Lewin schon älter sind, sind sie immer noch von wesentlicher Bedeutung in der Organisationsentwicklung und verfolgen einen langfristigen ganzheitlichen Ansatz der Veränderung (Bergmann & Garrecht, 2016). In der Praxis wird daher oftmals noch von geplantem Wandel ausgegangen (Opoku, 2016) und viele neuere Ansätze beruhen auf seinen Überlegungen (Burnes, 2017). So stellen modernere Phasenmodelle des Change Managements nicht selten eine differenziertere Weiterentwicklung des 3-Phasen-Modells nach Lewin dar, wie beispielsweise das 8-Phasen-Modell nach John P. Kotter oder Thomas Lauers Modell der „Erfolgsfaktoren im Change Management" (Burnes, 2017; Mast, 2020; Lauer, 2019).
Die Analyse der kommunalen Planungspraxis zur Auswahl und Bewertung von Siedlungsflächen in der Flächennutzungsplanung zeigt auf, welchen Einfluss Forschungsergebnisse auf die aktuelle Planungspraxis haben. Aufbauend auf einer Analyse des Forschungsstandes und der rechtlichen Rahmenbedingungen wird die Bewertung von Siedlungsflächen in 29 verschiedenen Flächennutzungsplänen untersucht. Als Ergebnis wurde ermittelt, dass in der Planungspraxis die Anzahl der Bewertungskriterien und die Komplexität der Bewertung in den letzten Jahren stark zugenommen hat. Außerdem kann gezeigt werden, dass und wie stark sich die Planungsmethodik und die verwendeten Kriterien zur Auswahl und Bewertung von Siedlungsflächen zwischen den einzelnen Gemeinden unterscheiden. Trotz umfangreicher anwendungsorientierter Forschung seit den 1990er Jahren zur Bewertung und Auswahl von Siedlungsflächen lassen sich jedoch nur indirekte Einflüsse der Forschungsergebnisse auf die Planungspraxis identifizieren. Teilweise wurde allerdings festgestellt, dass auch von den Gemeinden selbst neue Kriterien und Vorgehensweisen entwickelt werden.
1. Flower strips are a fundamental part of agri-environment schemes (AESs) introduced by the European Union to counteract the loss of biodiversity and related ecosystem services in agricultural landscapes. Although vegetation composition of the strips is essential for most fauna groups, comprehensive studies analysing vegetation development and influencing factors are rare.
2. From 2017 to 2019, we investigated the vegetation composition of 40 perennial wildflower strips (WFSs) implemented in 2015 or 2016, and 20 cereal fields without WFS across Saxony-Anhalt, Germany. We analysed environmental factors on plot (cover of grasses, shading, soil fertility) and four landscape-scale levels (habitat diversity, proportion of WFS and open habitats). The provision of nectar and pollen resources was estimated by the newly developed Pollinator Feeding Index (PFI). All strips had been implemented by farmers as AES with species- rich seed mixtures comprising 30 native forbs.
3. In all study years, forb species richness, cover and related nectar and pollen supply were much higher on WFSs than on controls, confirming the effectiveness of this AES. Although sown native forbs contributed the most to the high PFI values, spontaneously established forbs expanded the total range of species considerably, especially in winter and spring. While sown forb communities remained similar over time, spontaneous forbs showed a higher species turnover. Altogether, shading and grass cover had the greatest negative effect on the performance of the sown forbs. Landscape variables had only minor effects and were inconsistent in their importance across scale levels and years.
4. Synthesis and applications. Successfully established perennial wildflower strips (WFSs) sown with species-rich native seed mixtures provided a forb-rich and diverse vegetation throughout the AES funding period of 5 years. By supplying feeding resources for pollinators under various landscape situations, WFSs have significant potential to promote farmland biodiversity and related ecosyste services. We recommend the mandatory use of species-rich wildflower mixtures for perennial flower strips and to avoid their creation in heavily shaded field edges. Advisory services for farmers are necessary to prevent failures in WFS implementation and management and to improve their ecological effectiveness.
Nervenkompressionssyndrome („Engpass-Syndrome“) wie Karpaltunnelsyndrom, Radikulopathien oder radikulärer Schmerz sind die häufigsten peripheren Nervenläsionen und auch die häufigste Ursache für neuropathischen Schmerz. Trotz ihrer hohen Prävalenz stellen sie diagnostisch und therapeutisch weiterhin oft eine klinische Herausforderung dar. Die vorliegende Übersicht bietet aktuelle Informationen zur Ätiologie und Pathophysiologie von Nervenkompressionssyndromen; dafür wird die Evidenz aus präklinischen wie auch klinischen Studien zusammengefasst. Mögliche Mechanismen werden in den Kontext klinischer Befunde gestellt. Das aktuelle diagnostische Vorgehen wird erörtert, diagnostische Fallstricke werden beleuchtet. Zuletzt fasst der Beitrag die Evidenz für die nichtinvasive und chirurgische Therapie häufiger Nervenkompressionssyndrome zusammen und zeigt zukünftige Forschungsbereiche auf.
In der qualitativen Studie soll erstmalig ein realitätsnahes Abbild der Zusammenarbeit mit ausländischen Ärzten/innen aus der Perspektive der Pflege dargestellt werden. Es wurden 11 leitfadengestützte Interviews mit 13 Pflegekräften geführt und mittels der Grounded Theory ausgewertet. Alle Pflegekräfte berichten von alltäglichen Herausforderungen, wobei sprachliche Barrieren und die Einstellung zur Gleichberechtigung von Mann und Frau am häufigsten genannt wurden. Es wurde deutlich, dass die Kliniken vor der Aufgabe stehen, das Personalmanagement zu professionalisieren, um den langfristig bestehenden Konflikten entgegenzuwirken
