description: Purpose: Based on clinical and molecular data, breast cancer is a heterogeneous disease. Breast cancers that have no expression of estrogen receptor (ER), progesterone receptor (PR) and human epidermal growth factor receptor 2 (HER2) are defined as triple negative breast cancers (TNBC); luminal cancers have different expressions of ER, PR and/or HER2. TNBC are frequently linked with advanced disease, poor prognosis and occurrence in young African women, and about 15% of the cases are associated with germline BRCA1/2 mutations. Since radiotherapy is utilised as a principle treatment in the management of TNBC, we aimed to investigate the chromosomal instability and radiosensitivity of lymphocytes in TNBC patients compared to luminal breast cancer patients and healthy controls using the micronucleus (MN) assay. The effect of mutations in breast cancer susceptibility genes on chromosomal radiosensitivity was also evaluated. Methods: Chromosomal radiosensitivity was evaluated in the G0 (83 patients and 90 controls) and S/G2 (34 patients and 17 controls) phase of the cell cycle by exposing blood samples from all patients and controls to 2 and 4 Gy ionising radiation (IR). Results: In the G0 MN assay, the combined cohort of all breast cancer, TNBC and luminal patients’ exhibit significantly elevated spontaneous MN values compared to controls indicating chromosomal instability. Chromosomal radiosensitivity is also significantly elevated in the combined cohort of all breast cancer patients compared to controls. The TNBC patients, however, do not exhibit enhanced chromosomal radiosensitivity. Similarly, in the S/G2 phase, 76% of TNBC patients do not show enhanced chromosomal radiosensitivity compared to the controls. In both the G0 and S/G2 phase, luminal breast cancer patients demonstrate a shift towards chromosomal radiosensitivity compared to TNBC patients and controls. Conclusions: The observations of the MN assay suggest increased chromosomal instability and chromosomal radiosensitivity in South African breast cancer patients. However, in TNBC patients, the irradiated MN values are not elevated. Our results suggest that the healthy lymphocytes in TN patients could handle higher doses of IR.

description: This thesis focuses on power structures in the Mälaren basin during the Iron Age, and how these structures change over time. In the veiwpoint of the author, constructing large mounds vas an important way for the elite in the Mälaren basin to distinguish themelves from other groups in the region during the relevant period. By studying how the mounds differ in size an contents in relation to the norm, at least two different social strata can be discernd. The lower stratum vas similar to warriors than head of power, and vice versa. The burial mounds from The Late Iron Age are almost always located in burial-grounds which belong to villages and farms, which often extend back to the transition between Roman Iron Age and Migration period. The analysis also reveals that large mounds were built mainly in the Vendel period (AD 550-700) and the late Viking Age (tenth century). To find out how the elite used the large mounds in their social strategies, the author conducts a landscape-archaeological analysis. The analysis shows that large mound often are situated in important junctions in the landscapes, some served at meeting places for the Ting, but they seldom coincides with cult places, insted the cult places are often situated on the perifery of the settlement complexes with large mounds. Finally the author sets the results of analysis in a culture-historical context. The discussion focuses on when and why large mounds were built in the Mälaren basin during the Iron Age.

description: NIO1 is a compact and flexible radiofrequency H- ion source, developed by Consorzio RFX and INFN-LNL. Aim of the experimentation on NIO1 is the optimization of both the production of negative ions and their extraction and beam optics. In the initial phase of its commissioning, NIO1 was operated with nitrogen, but now the source is regularly operated also with hydrogen. To evaluate the source performances an optical emission spectroscopy diagnostic was installed. The system includes a low resolution spectrometer in the spectral range of 300-850 nm and a high resolution (50 pm) one, to study respectively the atomic and the molecular emissions in the visible range. The spectroscopic data have been interpreted also by means of a collisional-radiative model developed at IPP Garching. Besides the diagnostic hardware and the data analysis methods, the paper presents the first plasma measurements across a transition to the full H mode, in a hydrogen discharge. The characteristic signatures of this transition in the plasma parameters are described, in particular the sudden increase of the light emitted from the plasma above a certain power threshold.

description: The MAB phases are atomically layered, ternary or quaternary transition metal (M) borides (TMBs), with the general formula (MB)2zAx(MB2)y (z = 1–2; x = 1–2; y = 0–2), whose structures are composed of a transition M-B sublattices interleaved by A-atom (A = Al,Zn) mono- or bilayers. Most of the MAB phases were discovered before the 1990s, but recent discoveries of intriguing magnetocaloric properties, mechanical deformation behaviour, catalytic properties, and high-temperature oxidation resistance has led to their ‘re-discovery’. Herein, MAB phase synthesis is reviewed and their magnetic, electronic, thermal, and mechanical properties are summarized. Because the M-B layers in the MAB phases structurally resemble their corresponding binaries of the same M:B stoichiometry, the effects of the A-layers on properties are discussed. Inconsistencies in the literature are critically assessed to gain insights on the processing-structure-property relations, suggest fruitful avenues for future research, and identify limitations for prospective applications.

description: This paper is about the bar recursion operator in the context of classical realizability. After the pioneering work of Berardi, Bezem & Coquand [1], T. Streicher has shown [10], by means of their bar recursion operator, that the realizability models of ZF, obtained from usual models of $λ$-calculus (Scott domains, coherent spaces, . . .), satisfy the axiom of dependent choice. We give a proof of this result, using the tools of classical realizability. Moreover, we show that these realizability models satisfy the well ordering of $\mathbb{R}$ and the continuum hypothesis These formulas are therefore realized by closed $λ_c$-terms. This allows to obtain programs from proofs of arithmetical formulas using all these axioms.

description: Objective:Eradication of hepatitis C virus (HCV) in HIV disease decreases liver and non-liver-related morbidity and mortality. Elevated markers of monocyte/macrophage activation (soluble CD163 and sCD14) are associated with excess non-AIDS morbidity and mortality in HIV. We examined the effect of HCV eradication on these markers in relation to change in hepatic fibrosis.Design:A nested substudy within a longitudinal observational cohortMethods:We studied 126 HIV/HCV-coinfected women successfully treated for HCV, with undetectable HCV RNA at least 12 weeks after therapy completion. sCD163 and sCD14 were measured in serum collected before and after HCV eradication. Results were correlated with changes in markers of hepatic fibrosis.Results:Mean age of participants was 56.3 years, mean CD4+cell count was 615, and 72% had suppressed HIV RNA. After treatment, sCD163 and sCD14 levels significantly decreased from pre-treatment levels in unadjusted analyses. After adjusting for age, race, hepatic fibrosis status, baseline HCV RNA, CD4 count and HIV RNA status, cigarette smoking, and alcohol use, the decreases in sCD163 and sCD14 remained significant. Decrease in pre-treatment to post-treatment sCD163 were significantly positively correlated with changes in FIB-4 (r = 0.250, P = 0.005) and APRI (r = 0.262, P = 0.003); similarly decrease in sCD14 was significantly positively correlated with changes in FIB-4 (r = 0.333, P = 0.0001) and APRI (r = 0.457, P < 0.0001).Conclusion:HCV eradication is associated with significant reductions in monocyte/macrophage activation markers that correlate with reductions in markers of hepatic fibrosis. These findings support broad access to and early initiation of HCV treatment in order to decrease immune activation and improve health in HIV-infected persons.

description: This paper studies the problem of data-adaptive representations for big, distributed data. It is assumed that a number of geographically-distributed, interconnected sites have massive local data and they are interested in collaboratively learning a low-dimensional geometric structure underlying these data. In contrast to previous works on subspace-based data representations, this paper focuses on the geometric structure of a union of subspaces (UoS). In this regard, it proposes a distributed algorithm---termed cloud K-SVD---for collaborative learning of a UoS structure underlying distributed data of interest. The goal of cloud K-SVD is to learn a common overcomplete dictionary at each individual site such that every sample in the distributed data can be represented through a small number of atoms of the learned dictionary. Cloud K-SVD accomplishes this goal without requiring exchange of individual samples between sites. This makes it suitable for applications where sharing of raw data is discouraged due to either privacy concerns or large volumes of data. This paper also provides an analysis of cloud K-SVD that gives insights into its properties as well as deviations of the dictionaries learned at individual sites from a centralized solution in terms of different measures of local/global data and topology of interconnections. Finally, the paper numerically illustrates the efficacy of cloud K-SVD on real and synthetic distributed data.

description: Weight and body mass index (BMI) change was assessed among women after switch to integrase inhibitors (INSTIs) and/or tenofovir alafenamide (TAF). From 2006 to 2019, 1,458 women living with HIV enrolled in the Women's Interagency HIV Study and on antiretroviral therapy (ART) with ≥1 study visit before and after switching to INSTIs and/or TAF were included. Weight and BMI were compared pre- and postswitch to INSTI (by class and type) and/or TAF using multivariable linear mixed effects models; all models were also stratified by preswitch presence or absence of obesity (BMI ≥30 vs. <30 kg/m2). Mean age preswitch was 47 ± 6 years, 64% were black, mean CD4 = 475 ± 201 cells/mm3, 56% had HIV RNA <200 copies/mL, 36% switched to TAF but not INSTI, 60% to INSTI but not TAF, and 3.5% to TAF+INSTI. Time from pre- to postswitch was 12.8 ± 11.8 months. The INSTI-only group but not TAF groups had small but significant increases in weight and BMI: mean 79.2-80.6 kg and 30.2-30.7 kg/m2, p's < .001, respectively, with congruent findings by INSTI type (p's ≤ .01). In stratified (preswitch BMI) analyses, only nonobese subgroups experienced increases in weight and BMI across all ART treatment groups (p's < .05). Significant, although small-to-medium, increases in weight and BMI occurred among nonobese women who switched to INSTIs and/or TAF over short follow-up. Given long-term health consequences of obesity particularly as a low-grade inflammatory condition, identifying women at highest risk of ART-associated weight gain is imperative.

description: Purpose: To assess cross-population linkages in HIV/AIDS epidemics, we tested the hypothesis that the number of newly diagnosed AIDS cases among Black people who inject drugs (PWID) was positively related to the natural log of the rate of newly diagnosed HIV infections among Black non-PWID heterosexuals in 84 large U.S. metropolitan statistical areas (MSAs) in 2008–2016. Methods: We estimated a multilevel model centering the time-varying continuous exposures at baseline between the independent (Black PWID AIDS rates) and dependent (HIV diagnoses rate among Black heterosexuals) variables. Results: At MSA level, baseline (standardized β = 0.12) Black PWID AIDS rates and change in these rates over time (standardized β = 0.11) were positively associated with the log of new HIV diagnoses rates among Black heterosexuals. Thus, MSAs with Black PWID AIDS rates that were 1 standard deviation= higher at baseline also had rates of newly diagnosed HIV infections among Black non-PWID heterosexuals that were 10.3% higher. A 1 standard deviation increase in independent variable over time corresponded to a 7.8% increase in dependent variable. Conclusions: Black PWID AIDS rates may predict HIV rates among non-PWID Black heterosexuals. Effective HIV programming may be predicated, in part, on addressing intertwining of HIV epidemics across populations.

description: Background: Human immunodeficiency virus (HIV) infection may accelerate development of aging-related non-AIDS comorbidities (NACMs). The incidence of NACMs is poorly characterized among women living with HIV (WLWH). Methods: WLWH and HIV-seronegative participants followed in the Women's Interagency HIV Study (WIHS) through 2009 (when >80% of WLWH used antiretroviral therapy) or onward were included, with outcomes measured through 31 March 2018. Sociodemographics, clinical covariates, and prevalent NACM were determined at enrollment. We used Poisson regression models to determine incident NACM burden (number of NACMs accrued through most recent WIHS visit out of 10 total NACMs assessed) by HIV serostatus and age. Results: There were 3129 participants (2239 WLWH, 890 HIV seronegative) with 36 589 person-years of follow-up. At enrollment, median age was 37 years, 65% were black, and 47% currently smoked. In fully adjusted analyses, WLWH had a higher incident NACM rate compared with HIV-seronegative women (incidence rate ratio, 1.36 [95% confidence interval (CI), 1.02-1.81]). Incident NACM burden was higher among WLWH vs HIV-seronegative women in most age strata (HIV × age interaction: P = .0438), and women <25 years old had the greatest incidence rate ratio by HIV serostatus at 1.48 (95% CI, 1.19-1.84) compared with those in older age groups. Incident NACM burden was associated with traditional comorbidity risk factors but not HIV-specific indices. Conclusions: Incident NACM burden was higher among WLWH than HIV-seronegative women. This difference was most dramatic among women aged <25 years, a group for whom routine comorbidity screening is not prioritized. Established non-HIV comorbidity risk factors were significantly associated with incident NACM burden. More data are needed to inform best practices for NACM screening, prevention, and management among WLWH, particularly young women.

description: The ELISE test facility at IPP Garching hosts a RF H-/D- ion source and an acceleration system. Its target is to demonstrate the performance foreseen for the ITER NBI system in terms of extracted current density (H/D), fraction of co-extracted electrons and pulse duration. The size of the ELISE extraction area is half that foreseen for the ITER NBI. This paper presents a detailed study of the ELISE beam divergence and uniformity. In particular, it was possible to describe the beam as the sum of two components at very different divergence: about 2° vs. 5°÷7°. As test cases, the beam properties have been measured as function of two source parameters. The first one is the current flowing through the grid facing the plasma, the Plasma Grid, in order to generate the magnetic filter field. The second one is the bias current flowing between the Plasma Grid and the source walls. Both the filter field and the bias current influence the fraction of co-extracted electrons, but also the properties of the plasma just in front of the extraction system and the beam properties. The divergence and the uniformity of the beam have been measured by a Beam Emission Spectroscopy (BES) diagnostic; the detailed analysis of the raw spectra collected by BES led to describing the beam with two components of different divergence. This concept has been supported by the information given by thermal imaging of the diagnostic calorimeter. Further support to the proposed beam model has been found in the behavior of the currents flowing in the acceleration system and beamline components; these currents are given by the most divergent (charged) particles of the beam.

description: Background: Primary human papillomavirus (HPV) screening (PHS) utilizes oncogenic human papillomavirus (oncHPV) testing as the initial cervical cancer screening method and typically, if positive, additional reflex-triage (eg, HPV16/18-genotyping, Pap testing). While US guidelines support PHS usage in the general population, PHS has been little studied in women living with HIV (WLWH). Methods: We enrolled n = 865 WLWH (323 from the Women's Interagency HIV Study [WIHS] and 542 from WIHS-affiliated colposcopy clinics). All participants underwent Pap and oncHPV testing, including HPV16/18-genotyping. WIHS WLWH who tested oncHPV[+] or had cytologic atypical squamous cells of undetermined significance or worse (ASC-US+) underwent colposcopy, as did a random 21% of WLWH who were oncHPV[-]/Pap[-] (controls). Most participants additionally underwent p16/Ki-67 immunocytochemistry. Results: Mean age was 46 years, median CD4 was 592 cells/μL, 95% used antiretroviral therapy. Seventy WLWH had histologically-determined cervical intraepithelial neoplasia grade 2 or greater (CIN-2+), of which 33 were defined as precancer (ie, [i] CIN-3+ or [ii] CIN-2 if concurrent with cytologic high grade squamous intraepithelial lesions [HSILs]). PHS had 87% sensitivity (Se) for precancer, 9% positive predictive value (PPV), and a 35% colposcopy referral rate (Colpo). "PHS with reflex HPV16/18-genotyping and Pap testing"had 84% Se, 16% PPV, 30% Colpo. PHS with only HPV16/18-genotyping had 24% Colpo. "Concurrent oncHPV and Pap Testing"(Co-Testing) had 91% Se, 12% PPV, 40% Colpo. p16/Ki-67 immunochemistry had the highest PPV, 20%, but 13% specimen inadequacy. Conclusions: PHS with reflex HPV16/18-genotyping had fewer unnecessary colposcopies and (if confirmed) could be a potential alternative to Co-Testing in WLWH.

description: Current technological advances open up new opportunities for bringing human-machine interaction to a new level of human-centered cooperation. In this context, a key issue is the semantic understanding of the environment in order to enable mobile robots more complex interactions and a facilitated communication with humans. Prerequisites are the vision-based registration of semantic objects and humans, where the latter are further analyzed for potential interaction partners. Despite significant research achievements, the reliable and fast registration of semantic information still remains a challenging task for mobile robots in real-world scenarios. In this paper, we present a vision-based system for mobile assistive robots to enable a semantic-aware environment perception without additional a-priori knowledge. We deploy our system on a mobile humanoid robot that enables us to test our methods in real-world applications.

description: Stigma in health care settings can have negative consequences on women living with HIV, such as increasing the likelihood of missed visits and reducing trust in their clinical providers. Informed by prior stigma research and considering knowledge gaps related to the effect of patient-provider race concordance, we conducted this study to assess if patient-provider race concordance moderates the expected association between HIV-related stigma in health care settings and patients' trust in their providers. Moderation analyses were conducted using Women's Interagency HIV Study data (N = 931). We found significant main effects for patient-provider race concordance. Higher experienced stigma was associated with lower trust in providers in all patient-provider race combinations [White-White: B =-0.89, standard error (SE) = 0.14, p = 0.000, 95% confidence interval, CI (-1.161 to-0.624); Black patient-White provider: B =-0.19, SE = 0.06, p = 0.003, 95% CI (-0.309 to-0.062); and Black-Black: B =-0.30, SE = 0.14, p = 0.037, 95% CI (-0.575 to-0.017)]. Higher anticipated stigma was also associated with lower trust in providers [White-White: B =-0.42, SE = 0.07, p = 0.000, 95% CI (-0.552 to-0.289); Black patient-White provider: B =-0.17, SE = 0.03, p = 0.000, 95% CI (-0.232 to-0.106); and Black-Black: B =-0.18, SE = 0.06, p = 0.002, 95% CI (-0.293 to-0.066)]. Significant interaction effects indicated that the negative associations between experienced and anticipated HIV-related stigma and trust in providers were stronger for the White-White combination compared with the others. Thus, we found that significant relationships between HIV-related experienced and anticipated stigma in health care settings and trust in providers exist and that these associations vary across different patient-provider race combinations. Given that reduced trust in providers is associated with antiretroviral medication nonadherence and higher rates of missed clinical visits, interventions to address HIV-related stigma in health care settings may improve continuum of care outcomes.

description: We demonstrate that a Weyl point, widely examined in 3D Weyl semimetals and superfluids, can develop a pair of non-degenerate gapless spheres. Such a bouquet of two spheres is characterized by three distinct topological invariants of manifolds with full energy gaps, i.e., the Chern number of a 0D point inside one developed sphere, the winding number of a 1D loop around the original Weyl point, and the Chern number of a 2D surface enclosing the whole bouquet. We show that such structured Weyl points can be realized in the superfluid quasiparticle spectrum of a 3D degenerate Fermi gas subject to spin-orbit couplings and Zeeman fields, which supports Fulde-Ferrell superfluids as the ground state.

description: Topological quantum systems subjected to an even (resp. odd) time-reversal symmetry can be classified by looking at the related "Real" (resp. "Quaternionic") Bloch-bundles. If from one side the topological classification of these time-reversal vector bundle theories has been completely described in [DG1] for the "Real" case and in [DG2] for the "Quaternionic" case, from the other side it seems that a classification in terms of differential geometric invariants is still missing in the literature. With this article (and its companion [DG3]) we want to cover this gap. More precisely, we extend in an equivariant way the theory of connections on principal bundles and vector bundles endowed with a time-reversal symmetry. In the "Real" case we generalize the Chern-Weil theory and we showed that the assignment of a "Real" connection, along with the related differential Chern class and its holonomy, suffices for the classification of "Real" vector bundles in low dimensions.

description: Background: The prevalence and burden of age-related non-AIDS comorbidities (NACMs) are poorly characterized among women living with HIV (WLWH). Methods: Virologically suppressed WLWH and HIV-seronegative participants followed in the Women's Interagency HIV Study (WIHS) through at least 2009 (when >80% of WLWH used antiretroviral therapy) were included, with outcomes measured through 31 March 2018. Covariates, NACM number, and prevalence were summarized at most recent WIHS visit. We used linear regression models to determine NACM burden by HIV serostatus and age. Results: Among 3232 women (2309 WLWH, 923 HIV-seronegative) with median observation of 15.3 years, median age and body mass index (BMI) were 50 years and 30 kg/m2, respectively; 65% were black; 70% ever used cigarettes. WLWH had a higher mean NACM number than HIV-seronegative women (3.6 vs 3.0, P < .0001) and higher prevalence of psychiatric illness, dyslipidemia, non-AIDS cancer, kidney, liver, and bone disease (all P < .01). Prevalent hypertension, diabetes, and cardiovascular and lung disease did not differ by HIV serostatus. Estimated NACM burden was higher among WLWH versus HIV-seronegative women in those aged 40-49 (P < .0001) and ≥60 years (P = .0009) (HIV × age interaction, P = .0978). In adjusted analyses, NACM burden was associated with HIV, age, race, income, BMI, alcohol abstinence, cigarette, and crack/cocaine use; in WLWH, additional HIV-specific indices were not associated, aside from recent abacavir use. Conclusions: Overall, NACM burden was high in the cohort, but higher in WLWH and in certain age groups. Non-HIV traditional risk factors were significantly associated with NACM burden in WLWH and should be prioritized in clinical guidelines for screening and intervention to mitigate comorbidity burden in this high-risk population.

description: Purpose: Arthritis is associated with lost wages, work disability, and decreased productivity. There is a lack of knowledge regarding contextual factors that influence worker productivity to inform rehabilitation. Our study aims to identify the essential contextual factors that need to be considered when measuring worker productivity outcomes in people with arthritis. Materials and methods: A three-round international Delphi survey was performed. Round 1 (N = 50) elicited a comprehensive list of contextual factors. In Round 2 (N = 27), participants ranked their top ten factors from the list in Round 1. In Round 3 (N = 27), participants ranked their top five factors and their suggested outcome measures. Results: The key contextual factors identified in the Delphi are (1) type of job (e.g., level of physical demand, manual vs. sedentary), (2) personal factors (e.g., attitude, self-esteem, personal satisfaction, motivation), (3) disease state, (4) financial need, (5) societal incentive (e.g., insurance, government support, return to work transition programs), and (6) age. Conclusion: Future clinical trials in arthritis measuring worker productivity should consider the type of job (physical demands), personal factors, and disease state (as related to physical function). Contextual factors are not well investigated in the area but are crucial to developing the appropriate rehabilitation interventions.Implications for rehabilitationThis study identifies key contextual factors affecting worker productivity in people with arthritis: type of job, personal factors, disease state, financial need, societal incentive, and age.To facilitate proper interpretation of patient outcomes, rehabilitation professionals should consider contextual factors alongside their standard assessment tools.These findings provide a framework in designing rehabilitation programs and clinical trials on worker productivity in arthritis.

description: This study tested a conceptual psychosocial model of self-rated successful aging (SRSA) with HIV. Our sample (n = 356) included older women living with HIV (OWLH): average age 56.5 years, 73% Black. SRSA was assessed using a research-based 10-point scale (higher scores = better outcomes). We conducted adjusted structural equation modeling. The global model included two latent variables—protective attributes (composite of positive psychosocial factors: resilience, personal mastery, optimism, spirituality) and psychological distress (composite of negative psychosocial factors: anxiety, depression, loneliness, internalized HIV-related stigma). The model showed good fit (χ2(58) = 76, p = 0.06; RMSEA = 0.03; CFI = 0.99). Increased protective attributes were associated with improved SRSA both directly and mediated by improved coping with stress. While psychological distress did not have a direct effect on SRSA, it was indirectly associated with worsened SRSA via diminished protective attributes and via decreased coping with stress. Findings suggest the need for interventions enhancing positive and mitigating negative psychosocial factors in OWLH.

description: Purpose: To explore the effects on and sustainability of physiotherapists’ clinical behavior when using facilitation to support the implementation of a behavioral medicine approach in primary health care for patients with persistent musculoskeletal pain. Methods: A quasi-experimental pre-/post-test trial was conducted. Fifteen physiotherapists were included in the experimental group, and nine in the control group. Based on social cognitive theory and the Promoting Action on Research Implementation in Health Services framework, facilitation with multifaceted implementation methods was used during a six-month period. Clinical behaviors were investigated with a study-specific questionnaire, structured observations, self-reports and patient records. Descriptive and non-parametric statistical methods were used for analyzing differences over time and effect size. Results: A sustained increase in self-efficacy for applying the behavioral medicine approach was found. Clinical actions and verbal expressions changed significantly, and the effect size was large; however, changes were not sustained at follow-ups. The behavioral changes were mainly related to the goal setting, self-monitoring and functional behavioral analysis components. No changes in clinical behavior were found in the control group. Conclusion: Tailored multifaceted facilitation can support the implementation of a behavioral medicine approach in physiotherapy in primary health care, but more comprehensive actions targeting sustainability are needed.Implications for rehabilitationTailored multifaceted facilitation can support the implementation of an evidence based behavioral medicine approach in physiotherapy.Facilitation can be useful for increasing self-efficacy beliefs for using behavioral medicine approach in physiotherapist’s clinical practice.Further research is required to establish strategies that are effective in sustaining behavioral changes.

description: For a fixed $K\gg 1$ and $n\in\mathbb{N}$, $n\gg 1$, we study metric spaces which admit embeddings with distortion $\le K$ into each $n$-dimensional Banach space. Classical examples include spaces embeddable into $\log n$-dimensional Euclidean spaces, and equilateral spaces. We prove that good embeddability properties are preserved under the operation of metric composition of metric spaces. In particular, we prove that any $n$-point ultrametric can be embedded with uniformly bounded distortion into any Banach space of dimension $\log n$. The main result of the paper is a new example of a family of finite metric spaces which are not metric compositions of classical examples and which do embed with uniformly bounded distortion into any Banach space of dimension $n$. This partially answers a question of G. Schechtman.

description: Führungskräfte haben eine zentrale Rolle für den Erfolg von Sicherheit und Gesundheit bei der Arbeit. Unternehmensleitungen entscheiden darüber, ob und wie viele Ressourcen für diese Themen zur Verfügung gestellt werden und darüber, wie umfassend Prävention in der Unternehmensstrategie verankert wird, während die mittlere Führungsebene für die Durchführung und Nachhaltigkeit von Interventionen wichtig ist (Elke et al., 2015). Beide Gruppen haben zudem eine Vorbild- und Modellwirkung und beeinflussen die Sicherheits- und Gesundheitskultur in Unternehmen (Cooper, 2016). Unternehmensleitungen und Führungskräfte werden dementsprechend primär als ‚Promotoren‘ und Verantwortliche für Sicherheit und Gesundheit angesehen. In kleinen und mittelständischen Unternehmen (KMU) mit flacheren Hierarchien, direkteren Entscheidungswegen und einer häufig eher familiären Kultur ist deren Rolle noch zentraler (Beck, 2011). Bei dieser Betrachtung wird jedoch oftmals ausgeklammert, dass Unternehmensleitung und Führungskräfte auch selbst (Mit-) Betroffene von schädlichen oder förderlichen Arbeitsbedingungen sind. Sie sind nicht nur Mittler, sondern haben als direkte Zielgruppe für Interventionen in Sicherheit und Gesundheit eine große Bedeutung.
