Das Thema Gender wird im Marketing kontrovers diskutiert. Als Orientierungspunkt für einen angemessenen Umgang wird häufig das Nachhaltigkeitsziel Nr. 5 Geschlechtergleichstellung der Vereinten Nationen genannt. Dieser Artikel geht mit Hilfe einer Literaturanalyse der Frage nach, inwieweit Forschungsergebnisse aus der führenden Marketingliteratur geeignet sind, Gleichstellung im Sinne des Ziels Nr. 5 voranzutreiben. Dabei wird zunächst das Ziel Nr. 5 erläutert und dann betrachtet, welchen Beitrag es für das Marketing Management zur Zielerreichung ermöglicht. Die Erkenntnisse aus der Forschung bieten eine Basis, wie in der Marketing-Praxis gendersensibel agiert werden kann.
Establishment of calcareous grassland on ex-arable fields by introducing target species is one of the most frequently used methods to restore the species assemblages of this highly endangered habitat type. The present study evaluates the long-term success of calcareous grassland restoration on former arable land in the vicinity of one of the oldest nature reserves in Bavaria, the “Garchinger Heide”. The restoration experiment combined different measures like topsoil removal, transfer of freshly cut seed-containing hay and additional sowing to the following variants in a 21-year experiment: (1) No topsoil removal, no hay transfer (control), (2) no topsoil removal with immediate hay transfer, (3) topsoil removal with immediate hay transfer and (4) topsoil removal with hay transfer 10 years after the start of restoration. Eleven Red List species which had not been transferred successfully were additionally sown after 9 to 19 years. Due to a limited availability of seeds, sowing of these species was mainly restricted to areas with topsoil removal, where better establishment was expected due to low vegetation cover. Five rare species with abundant seed production were also sown to plots without topsoil removal and hay transfer. The nature reserve served both as the donor area of the target species and as the reference to evaluate restoration success. Regarding aboveground biomass and total vegetation cover, greatest similarity to the donor site was observed on plots without topsoil removal. In contrast, the highest numbers of target species occurred on plots with topsoil removal, hay transfer and additional sowing. Similarity in species composition between restoration sites and the reference area increased over time, but species composition of restored sites did not fully reflect the reference after 21 years. One reason for the remaining dissimilarity was probably that topsoil removal favored stress tolerant species which were less common on the mature and more fine-grained soils of the nature reserve. Plots without topsoil removal still differed from the reference by their high vegetation cover and a significantly higher proportion of mesophytic grassland species. The study also showed that 19 Red List species were successfully established on the former arable fields, eight of them presumably by sowing. Nevertheless, various other rare species have not been observed yet. Results on functional traits characterizing environmental adaptation and reproduction also underlined the differences between restoration plots and the reference site. Our study presents a ʽdynamic restoration approachʼ where managers evaluated the original factorial treatments after a decade and modified them by additional treatments where development was sub-optimal. Such additional treatments may have confounded the experimental design, but from a management perspective proved to be a promising option to establish species rich grassland of high conservation value with a reasonable expenditure of time.
Within the frame of the EU Common Agricultural Policy, most countries subsidise the establishment and maintenance of perennial flower strips on arable land within Agri-Environmental Schemes to provide foraging habitats and refuges for wildlife.
In a replicated field experiment, we studied the effects of different types of seed mixtures on the establishment and maintenance of perennial flower strips on fertile arable land in the federal state of Saxony-Anhalt, Germany over seven years. The seed mixtures were commonly applied within recent Common Agricultural Policy funding periods: (1) a low-diversity cultivar standard seed mixture (CULTIVAR), (2) a high-diversity cultivar and native plant mixture (MIX), and (3) a high-diversity native plant mixture (WILDFLOWER). All plots were mulched every year in March and at the beginning of August.
The low success of CULTIVAR triggered the massive encroachment of spontaneously established perennial grasses. In MIX, too, cultivars have disappeared after the first year. Both wildflower variants were successful in maintaining a high cover of sown perennial native forbs and a high ratio of established sown species, even after seven years. WILDFLOWER always tended to show better values than MIX. Furthermore, spontaneously establishing species began to spread their cover in MIX in the fifth year, with a very strongly increasing tendency, whereas in WILDFLOWER cover of spontaneously immigrating species stayed satisfyingly low.
Using native wildflowers to establish perennial wildflower strips was very effective in maintaining high species diversity within the Agri-Environmental Schemes funding period of five years and beyond. WILDFLOWER was especially successful. On the other hand, CULTIVAR failed completely. On fertile soils in regions with rather low yearly precipitation, mulching twice a year supported the maintenance of perennial wildflower strips.
Extensive green roofs (EGRs) offer several beneficial ecosystem services for sustainable urban development. However, most standard green roofs have been designed with species-poor plant mixtures containing non-native species. Aiming to increase the nature conservation values of EGRs, we developed and tested a vascular plant seed mixture including regionally occurring native sandy dry grassland species in experimental miniature roofs in Northwestern Germany (temperate oceanic climate) over 4 years. We tested the mixture at two seed densities (1 and 2 g/m2). Additionally, we tested seeding at 1 g/m2 and introducing raked plant material collected from an ancient dry grassland. The total establishment rates of sown species reached 92–96% in the first year, but dropped to 40–60% in the last 2 years, with the highest values for the plots with raked material. Twenty-four additional species (11 vascular, 7 lichen, and 6 moss species, including 7 red-list species) typical of sandy dry grasslands were introduced through the raked material. Vascular plants reached 60–70% cover in the second year. Severe drought periods in the third and the fourth year led to a strong decline of vascular plant cover then. As this cover was higher in the plots with raked material, we assume facilitative effects through the well-developed cryptogam layer containing a mix of pleurocarpous and acrocarpous mosses and lichens. Spontaneously establishing acrocarpous mosses in sown plots did not seem to provide this same function. We conclude that EGRs designed with regionally occurring sandy dry grassland plant species and especially the application of raked plant material from ancient grassland is a fruitful approach to increase the value of green roofs for native phytodiversity.
Ecological restoration of an urban demolition site through introduction of native forb species
(2020)
Urban brownfields can provide habitats for endangered native plant species but may also support invasive non native species. The aim of our study was to develop and test different measures for the ecological restoration of an urban brownfield. We aimed to enhance native plant species richness by seeding two native forb seed mix tures containing 25 (HD-mixture) and 13 species (LD-mixture), respectively, without affecting spontaneously colonizing plant species of nature conservation value. Additionally, we tested the effects of species introduction and mowing on the establishment of invasive non-native plant species, woody species development, and per ennial grass dominance.
With establishment rates of 84% (HD) and 92% (LD) in the first study year and about 60% for both seed mixtures in the fourth year, species introduction was successful and led to rapid re-vegetation of the formerly bare brownfield. Although seeding did not result in increased species richness using either seed mixture, the dominance of perennial grasses was significantly reduced by the establishment of forb species from the HD mixture. Overall, we observed the spontaneous establishment of ten plant species of conservation value; seeding affected these species only temporarily, in the second year. Seeding (with either seed mixture) and mowing both resulted in reduced cover of woody species and a lower frequency of the invasive non-native Robinia pseudoa cacia.
Our study demonstrated the high nature conservation value of dry and nutrient-poor urban brownfields for spontaneously occurring threatened plant species. Further studies have to evaluate if the reduced cover of grasses and woody species through introduction of site-specific native forb species might increase these sites’ aesthetic value and broader acceptance of brownfields by urban residents.
Using eye-tracking, this study investigates fixation duration of students viewing pictures of pigs, which systematically vary in the facial expression of the pig and in the barn setting. The aim of this study is to analyze which picture elements are viewed and for how long, as well as how fixation times vary with a change of the expression of the pig and the barn type. The results show clear effects of picture composition: pig expression and pen type affect fixation durations of different areas of interest with the influence of the pig being considerably larger. Face regions are viewed longer in the “happy” pig, while floor/bedding and the eyes are viewed longer in pictures showing the “unhappy” pig which might be a hint for infor-mation search. The power of facial expressions, also for the depiction of farm animals, is a new finding of this paper, which might be of importance when select-ing agricultural pictures for different purposes.
Biofortified apples seem to be a suitable produce. In this study, different selenium forms and application levels were applied to the two apple varieties ‘Golden Delicious’ and ‘Jonagold’, grown in the years 2017 and 2018 in order to increase the selenium uptake within a typical Western diet. It was shown that the biofortification, which was performed as a foliar application implemented in usual calcium fertilization, led to significantly increased selenium contents in the fruits. Furthermore, biofortification affected the total phenolic content (TPC), the polyphenol oxidase activity (PPO), as well as the antioxidant activity (AOA), the latter measured with the two well-known assays Trolox Equivalent Antioxidant Capacity Assay (TEAC) and Oxygen Radical Absorbance Capacity Assays (ORAC). The varying selenium forms and application levels showed a differing influence on the parameters mentioned before. Higher fertilizer levels resulted in higher selenium accumulation. It was found that PPO activity fluctuates less in biofortified apples. With regard to TPC, selenate led to higher amounts when compared to the untreated controls and selenite resulted in lower TPC. AOA analysis showed no clear tendencies as a result of the selenium biofortification. In the case of ‘Jonagold’, a higher AOA was generally measured when being biofortified, whereas, in the case of ‘Golden Delicious’, only one form of application led to higher AOA. Additionally, differences in the amount of major phenolic compounds, measured with High Performance Liquid Chromatography Mass Spectrometry (HPLC-DAD-ESI-MSn), were observed, depending on the conditions of the biofortification and the variety.
Kreditfinanzierungen im Krankenhauswesen werden u. a. aufgrund bestehender Investitionsstaus und aktueller Herausforderungen aus dem Umgang mit der COVID-19-Pandemie weiter an Bedeutung gewinnen. Der folgende Beitrag fasst die Ergebnisse einer Anfang 2019 veröffentlichten Dissertation zusammen: eine Bestandsaufnahme und Analyse der heutigen Finanzkommunikation zwischen Krankenhaus und Kreditinstitut, die bestehende Problemfelder und kritische Faktoren der Finanzkommunikation identifiziert und Handlungsempfehlungen für beide Parteien zur Verbesserung der Finanzkommunikation und zur Begegnung der Herausforderungen zukünftiger Kreditfinanzierungen ableitet.
Model-derived relationships between chlorophyll a (Chl-a) and nutrients and temperature have fundamental implications for understanding complex interactions among water quality measures used for lake classification, yet accuracy comparisons of different approaches are scarce. Here, we (1) compared Chl-a model performances across linear and nonlinear statistical approaches; (2) evaluated single and combined effects of nutrients, depth, and temperature as lake surface water temperature (LSWT) or altitude on Chl-a; and (3) investigated the reliability of the best water quality model across 13 lakes from perialpine and central Balkan mountain regions. Chl-a was modelled using in situ water quality data from 157 European lakes; elevation data and LSWT in situ data were complemented by remote sensing measurements. Nonlinear approaches performed better, implying complex relationships between Chl-a and the explanatory variables. Boosted regression trees, as the best performing approach, accommodated interactions among predictor variables. Chl-a–nutrient relationships were characterized by sigmoidal curves, with total phosphorus having the largest explanatory power for our study region. In comparison with LSWT, utilization of altitude, the often-used temperature surrogate, led to different influence directions but similar predictive performances. These results support utilizing altitude in models for Chl-a predictions. Compared to Chl-a observations, Chl-a predictions of the best performing approach for mountain lakes (oligotrophic–eutrophic) led to minor differences in trophic state categorizations. Our findings suggest that both models with LSWT and altitude are appropriate for water quality predictions of lakes in mountain regions and emphasize the importance of incorporating interactions among variables when facing lake management challenges.
In der Corona-Pandemie ist es für nahezu alle Organisationen – von der Behörde, über die Unternehmung, bis hin zur Hochschule – zur Aufgabe geworden, den „richtigen“ Umgang mit der Krise zu finden. Was effektives Krisenmanagement ausmacht, soll deshalb vor dem Hintergrund des aktuellen Standes der Fachdiskussion beleuchtet und für eine Selbstreflexion aufbereitet werden, wie sie im Rahmen eines dualen Studiengangs eingeübt und im Sinne einer persönlichen Kompetenzentwicklung vertieft werden kann.
Nervenschmerz ist nicht gleich Nervenschmerz. Um Patienten mit ausstrahlenden Schmerzen, bei denen die Nerven eine Rolle spielen könnten, adäquat zu therapieren, sind eine gründliche Untersuchung und ein fundiertes Clinical Reasoning unerlässlich. Nur dadurch entpuppen sich die beiden Patientinnen mit fast identischen Symptomen als sehr unterschiedlich.
Wir kennen neurodynamische Tests und Behandlungsmethoden, nutzen diese alltäglich in der Praxis und gehen auf Kurse, um mehr darüber zu lernen. Aber was verstehen wir tatsächlich darunter? Kommen wir in unserem Verständnis darüber auf einen gemeinsamen Nenner? Dieser Artikel gibt einen Einblick in die Thematik Neurodynamik. Bisherige Überzeugungen stehen dabei auf dem Prüfstand.
This article is based on an international comparative social policy module held annually at Malmö University (Sweden) with partner universities from several countries. Our study examines the results of intra- and interpersonal dynamics among participants and lecturers, which we call "productive tension", in relation to overarching questions about knowledge acquisition and the importance of reflexivity and reflectivity in the learning process. Students and faculty create a "community of practice" (CoP) (Lave & Wenger 1991) that benefits from a continuous interactive environment and direct engagement. Our study uses a mixed method approach. The analysis considers qualitative data from interviews with the participating students and quantitative data from questionnaires. In this article, we focus on the productive tension inherent in the reflective and reflexive processes. Reflective and reflexive processes are identified that influence the students' experience of cross-border cooperation and their professional identity. Our study also demonstrates how the knowledge about "Social Work" as a profession can be broadened through international comparative teaching and learning. The main conclusion of this work is that reflective and reflexive learning processes in social work education enable participants to see and understand themselves from a broader perspective and strengthen their own professional identity.
Die Geschichte von »Wellness« lässt sich lange zurückverfolgen. Der Artikel stellt einige Eckpfeiler dieser bewegten Geschichte dar. Aufgezeigt wird vor allem, wie »Wellness« gerade im deutschsprachigen Raum auf offene Ohren stieß und wie der Begriff durch eine hemmungslose Kommerzialisierung seinen ursprünglichen Bedeutungsgehalt veränderte.
Entrapment neuropathies such as carpal tunnel syndrome, radiculopathies, or radicular pain are the most common peripheral neuropathies and also the most common cause for neuropathic pain. Despite their high prevalence, they often remain challenging to diagnose and manage in a clinical setting. Summarising the evidence from both preclinical and clinical studies, this review provides an update on the aetiology and pathophysiology of entrapment neuropathies. Potential mechanisms are put in perspective with clinical findings. The contemporary assessment is discussed and diagnostic pitfalls highlighted. The evidence for the noninvasive and surgical management of common entrapment neuropathies is summarised and future areas of research are identified.
Entrapment neuropathies are a heterogenous condition reflecting distinct underlying pathomechanisms. A contemporary assessment aimed at identifying potential mechanisms may help target management for these patients.
Die Gesundheits- und Kinderkrankenpflege ist ein grundlegender Bestandteil der Netzwerke „Früher Hilfen“, wenn es darum geht, Familien in herausfordernden sozialen und gesundheitlichen Lagen in der Häuslichkeit zu unterstützen. Dieses Arbeitsfeld ist für die Kinderkrankenpflege neu. Die dort stattfindenden Prozesse der Etablierung und deren Auswirkungen auf die Professionsentwicklung sind Forschungsgegenstand dieser Arbeit. Ziel ist es, die Situation der Gesundheits- und Kinderkrankenpflege im Arbeitsfeld Frühe Hilfen im Hinblick auf Professionalisierung und Professionalität zu analysieren. Dazu findet die Situationsanalyse als Weiterentwicklung der Grounded Theory Anwendung. In diesem Beitrag werden die Theoriebezüge und Methoden der Situationsanalyse von Clarke (2012; 2018) vor diesem Forschungshintergrund dargestellt. Anhand des Analyseprozesses werden die Mappingstrategien als Werkzeug der Situationsanalyse erläutert und beispielhaft veranschaulicht. Der methodische Zugewinn durch die Situationsanalyse für den Forschungsgegenstand wird diskutiert. Die Relevanz der Grounded Theory und der Situationsanalyse für die Pflegewissenschaft werden zusammenfassend erörtert.

In dieser Online-Befragung wird erforscht, ob eine OMT-Weiterbildung (orthopädische manuelle/manipulative Physiotherapie) die Employability (Beschäftigungsfähigkeit) verbessert und woran man eine Verbesserung erkennen könnte. Veränderungen durch die OMT-Weiterbildung, deren Vor- und Nachteile und weitere Themen waren Bestandteile der Befragung. Die statistische Auswertung erfolgte deskriptiv. 190 Fragebögen wurden ausgewertet, die Rücklaufquote lag bei 44,6 %.
Die Befragung zeigte, dass die OMT-Weiterbildung teilweise Vorteile mit sich bringt. Die Vorteile sind laut den Befragten eine verbesserte Behandlung und Beratung von Patienten, mehr Spaß und Motivation bei der Arbeit und eine erhöhte Patientenzufriedenheit. Keine Vorteile sind hingegen in Bezug auf eine bessere professionelle Position, Mehrverdienst oder eine verbesserte Zusammenarbeit mit den Krankenkassen zu erkennen. Zudem ist die Zufriedenheit mit dem Dachverband OMT-Deutschland eher gering. Dennoch würden über 90 % die OMT-Weiterbildung weiterempfehlen.
Es sollten weitere Studien in Bezug auf die Employability von Physiotherapeuten mit bestimmten Fort-/Weiterbildungen durchgeführt werden. Nach Aussagen der OMT-zertifizierten Physiotherapeuten nimmt die Employability nach der OMT-Weiterbildung zu. Die Beziehung zu dem Dachverband OMT-Deutschland scheint eher schwierig oder nicht vorhanden zu sein.
Eine Nackenflexion beeinflusst nachweislich die Mechanosensibilität von neurodynamischen Testungen der unteren Extremität. In der Literatur wird diskutiert, ob sich dieses Phänomen durch eine erhöhte (intraneurale) Spannung des Nervengewebes und/oder einen protektiven Reflexmechanismus des motorischen Systems erklären lässt. Bislang konnte kein protektiver Mechanismus in Form einer modifizierten muskulären Rekrutierung als mechanosensibler Parameter zwischen der passiven Nackenflexion und der unteren Extremität gemessen werden.
Alle in diese Querschnittsstudie eingeschlossenen 30 asymptomatischen, männlichen Probanden führten den neurodynamischen Straight-Leg-Raise-Test und Slump-Test durch. Um einen möglichen Einfluss der passiven Nackenflexion auf die muskuläre Rekrutierung der unteren Extremität festzustellen, wurden während dieser sensibilisierenden Bewegung die muskuläre Rekrutierung und das Bewegungsausmaß mittels Elektromyografie und Inertialsensorik (kinematische Messtechnik) gemessen.
Die Studienergebnisse bestätigten einen segmentübergreifenden Einfluss der passiven Nackenflexion auf die muskuläre Rekrutierung der unteren Extremität. Deren Muster deuten möglicherweise auf einen protektiven muskulären Mechanismus in endgradigen neurodynamischen Positionen hin.
Als Jane mit ihrer kleinen Schwester tobt, schießt ihr plötzlich ein starker Schmerz in Nacken und Kopf. So weit nicht ungewöhnlich und eine Indikation für Physiotherapie. Doch als die junge Studentin erzählt, dass der Kopfschmerz pulsierend ist, wird ihr Therapeut hellhörig und stellt die entscheidenden Fragen.
Objective
To identify assessment tools used to evaluate patients with temporomandibular disorders (TMD) considered to be clinically most useful by a panel of international experts in TMD physical therapy (PT).
Methods
A Delphi survey method administered to a panel of international experts in TMD PT was conducted over three rounds from October 2017 to June 2018. The initial contact was made by email. Participation was voluntary. An e-survey, according to the Checklist for Reporting Results of Internet E-Surveys (CHERRIES), was posted using SurveyMonkey for each round. Percentages of responses were analysed for each question from each round of the Delphi survey administrations.
Results
Twenty-three experts (completion rate: 23/25) completed all three rounds of the survey for three clinical test categories: 1) questionnaires, 2) pain screening tools and 3) physical examination tests. The following was the consensus-based decision regarding the identification of the clinically most useful assessments. (1) Four of 9 questionnaires were identified: Jaw Functional Limitation (JFL-8), Mandibular Function Impairment Questionnaire (MFIQ), Tampa Scale for Kinesiophobia for Temporomandibular disorders (TSK/TMD) and the neck disability index (NDI). (2) Three of 8 identified pain screening tests: visual analog scale (VAS), numeric pain rating scale (NRS) and pain during mandibular movements. (3) Eight of 18 identified physical examination tests: physiological temporomandibular joint (TMJ) movements, trigger point (TrP) palpation of the masticatory muscles, TrP palpation away from the masticatory system, accessory movements, articular palpation, noise detection during movement, manual screening of the cervical spine and the Neck Flexor Muscle Endurance Test.
Conclusion
After three rounds in this Delphi survey, the results of the most used assessment tools by TMD PT experts were established. They proved to be founded on test construct, test psychometric properties (reliability/validity) and expert preference for test clusters. A concordance with the screening tools of the diagnostic criteria of TMD consortium was noted. Findings may be used to guide policymaking purposes and future diagnostic research.
In den meisten Unternehmen stellt das Einstellungsinterview nach der Sichtung der Bewerbungsunterlagen die einzige Methode der Personalauswahl dar. Umso wichtiger ist es, dass diese Methode möglichst valide die Eignung der Kandidaten erfassen kann. Unbewusste Beurteilungen funken hier jedoch oft dazwischen. Eine Studie hat die Bedeutung der Ähnlichkeit zwischen Interviewer und Bewerber untersucht.
The Brief Symptom Inventory (BSI)-18 is a widely-used tool to assess changes in general distress in patients despite an ongoing debate about its factorial structure and lack of evidence for longitudinal measurement invariance (LMI). We investigated BSI-18 scores from 1,081 patients from an outpatient clinic collected after the 2nd, 6th, 10th, 18th, and 26th therapy session. Confirmatory factor analysis (CFA) was used to compare models comprising one, three, and four latent dimensions that were proposed in the literature. LMI was investigated using a series of model comparisons, based on chi-square tests, effect sizes, and changes in comparative fit index (CFI). Psychological distress diminished over the course of therapy. A four-factor structure (depression, somatic symptoms, generalized anxiety, and panic) showed the best fit to the data at all measurement occasions. The series of model comparisons showed that constraining parameters to be equal across time resulted in very small decreases in model fit that did not exceed the cutoff for the assumption of measurement in variance. Our results show that the BSI-18 is best conceptualized as a four-dimensional tool that exhibits strict longitudinal measurement invariance. Clinicians and applied researchers do not have to be concerned about the interpretation of mean differences over time.
