Authors: Nassauer Anne , Legewie Nicolas M. 
Published: July 2020

ZusammenfassungÜber Jahrzehnte wurde Gewalt durch Interviews mit Betroffenen oder Tätern, durch teilnehmende Beobachtung oder Gewaltstatistiken untersucht, meist unter Verwendung entweder qualitativer oder quantitativer Analysemethoden. Seit der Jahrhundertwende stehen Forschenden eine Reihe neuer Ansätze zur Verfügung: Es gibt immer mehr Videoaufnahmen von gewaltsamen Ereignissen, Mixed Methods-Ansätze werden stetig weiterentwickelt und durch Computational Social Sciences finden Big Data-Ansätze Einzug in immer mehr Forschungsfelder. Diese drei Entwicklungen bieten großes Potenzial für die quantitative und qualitative Gewaltforschung. Der vorliegende Beitrag diskutiert Videodatenanalyse, Triangulation und Mixed Methods-Ansätze sowie Big Data und bespricht den gegenwärtigen und zukünftigen Einfluss der genannten Entwicklungen auf das Forschungsfeld. Das Augenmerk liegt besonders darauf, (1) wie neuere Videodaten genutzt werden können, um Gewalt zu untersuchen und wo ihre Vor- und Nachteile liegen, (2) wie Triangulation und Mixed Methods-Ansätze umfassendere Analysen und theoretische Verknüpfungen in der Gewaltforschung ermöglichen und (3) wo Anwendungen von Big Data und Computational Social Science in der Gewaltforschung liegen können.
Experimental investigation of specific cutting forces and estimation of the heat partitioning under increasing tool wear in machining nickel-based super alloy IN 718
Authors: Augspurger Thorsten , Schraknepper Daniel , Bergs Thomas 
Published: July 2020

AbstractPresented are an experimental setup and affiliated methodology to measure the specific cutting forces in the milling process with proceeding tool wear at simplified orthogonal milling kinematics. The cutting forces, cutter rotation angle and chip temperature are acquired by a time sensitive measuring system consisting of a synchronized dynamometer, ratio pyrometer and spindle encoder. The approach allows the accurate acquisition of cutting forces under defined engagement conditions and thus constitutes a valuable basis for cutting force modelling and tool wear monitoring approaches. The results show uniformly and linearly increasing forces over the entire range of undeformed chip thickness due to wear. Besides a mechanical view on the cutting process, also the thermal domain was included into the analysis. Therefore, a ratio pyrometer was used as part of the synchronized measurement system tracking the chips backside temperature in order to estimate a virtually continuous heat flow into the chip. This heat flow increased with wear and process power, which indicates that the chip’s temperature can be used as process monitoring variable for tool wear.

Abstract
Purpose of Review
Molecular imaging with positron emission tomography (PET) is a powerful tool to visualize breast cancer characteristics. Nonetheless, implementation of PET imaging into cancer care is challenging, and essential steps have been outlined in the international “imaging biomarker roadmap.” In this review, we identify hurdles and provide recommendations for implementation of PET biomarkers in breast cancer care, focusing on the PET tracers 2-[18F]-fluoro-2-deoxyglucose ([18F]-FDG), sodium [18F]-fluoride ([18F]-NaF), 16α-[18F]-fluoroestradiol ([18F]-FES), and [89Zr]-trastuzumab.

Recent Findings
Technical validity of [18F]-FDG, [18F]-NaF, and [18F]-FES is established and supported by international guidelines. However, support for clinical validity and utility is still pending for these PET tracers in breast cancer, due to variable endpoints and procedures in clinical studies.

Summary
Assessment of clinical validity and utility is essential towards implementation; however, these steps are still lacking for PET biomarkers in breast cancer. This could be solved by adding PET biomarkers to randomized trials, development of imaging data warehouses, and harmonization of endpoints and procedures.
Correcting the Brain? The Convergence of Neuroscience, Neurotechnology, Psychiatry, and Artificial Intelligence
Authors: Rainey Stephen , Erden Yasemin J. 
Published: July 2020

AbstractThe incorporation of neural-based technologies into psychiatry offers novel means to use neural data in patient assessment and clinical diagnosis. However, an over-optimistic technologisation of neuroscientifically-informed psychiatry risks the conflation of technological and psychological norms. Neurotechnologies promise fast, efficient, broad psychiatric insights not readily available through conventional observation of patients. Recording and processing brain signals provides information from ‘beneath the skull’ that can be interpreted as an account of neural processing and that can provide a basis to evaluate general behaviour and functioning. But it ought not to be forgotten that the use of such technologies is part of a human practice of neuroscience informed psychiatry. This paper notes some challenges in the integration of neural technologies into psychiatry and suggests vigilance particularly in respect to normative challenges. In this way, psychiatry can avoid a drift toward reductive technological approaches, while nonetheless benefitting from promising advances in neuroscience and technology.

The tumors are organized based on growth patterns including thyroid neoplasms with predominantly papillary, follicular, solid, and spindle cell growth pattern, as well as neoplasms with distinct cytological characteristics. A special section is also dedicated to rare thyroid tumors with peculiar patterns including thyroid carcinoma with Ewing family tumor elements and intrathyroidal thymic-related neoplasms.
Cause analysis and solutions of water blocking damage in cracked/non-cracked tight sandstone gas reservoirs
Authors: Wang Jie , Zhou Fu-Jian 
Published: July 2020

AbstractAfter hydraulic fracturing treatment, a reduction in permeability caused by the invasion of fracturing fluids is an inevitable problem, which is called water blocking damage. Therefore, it is important to mitigate and eliminate water blocking damage to improve the flow capacities of formation fluids and flowback rates of the fracturing fluid. However, the steady-state core flow method cannot quickly and accurately evaluate the effects of chemical agents in enhancing the fluid flow capacities in tight reservoirs. This paper introduces a time-saving and accurate method, pressure transmission test (PTT), which can quickly and quantitatively evaluate the liquid flow capacities and gas-drive flowback rates of a new nanoemulsion. Furthermore, scanning electron microscopy (SEM) was used to analyze the damage mechanism of different fluids and the adsorption of chemical agents on the rock surface. Parallel core flow experiments were used to evaluate the effects of the nanoemulsion on enhancing flowback rates in heterogeneous tight reservoirs. Experimental results show that the water blocking damage mechanisms differ in matrices and fractures. The main channels for gas channeling are fractures in cracked cores and pores in non-cracked cores. Cracked cores suffer less damage from water blocking than non-cracked cores, but have a lower potential to reduce water saturation. The PTT and SEM results show that the permeability reduction in tight sandstones caused by invasion of external fluids can be list as guar gum fracturing fluid > slickwater > brine. Parallel core flow experiments show that for low-permeability heterogenous sandstone reservoirs with a certain permeability ratio, the nanoemulsion can not only reduce reverse gas channeling degree, but also increase the flowback rate of the fracturing fluid. The nanoemulsion system provides a new solution to mitigate and eliminate water blocking damage caused by fracturing fluids in tight sandstone gas reservoirs.
A non-Archie water saturation method for conventional reservoirs based on generalization of Passey TOC model for unconventional reservoirs
Authors: Oraby Moustafa 
Published: July 2020

AbstractThe determination of the formation water saturation, Sw, is a continuous process throughout the life of the fields. Multiple water saturation models are developed to increase the accuracy of calculating this critical parameter for both open-hole and cased-hole wells. All current open-hole water saturation models require prior knowledge of some field parameters namely; formation water resistivity, Rw, clay volume, Vc and rock electrical properties (m, n). It is normally assumed that those reservoir parameters as either constant for the entire reservoir section or change by zones. This is obviously an impractical assumption especially for the (m) and (n) parameters. Also, when a reservoir is under water injection for enhanced oil recovery, the water salinity may change throughout the reservoir, based on the distribution of the reservoir permeability and the salinity of the injected water, resulting in a variable Rw. This case represents a real challenge to the existing water saturation models. In this paper, a methodology to determine water saturation without the need for prior knowledge of the formation water resistivity or the rock electrical properties is developed. This approach is a generalization of the Passey total organic carbon, TOC, model which is developed to determine the organic richness of the unconventional reservoirs. The scientific basis of the method, the modification required to be applied in conventional reservoirs, the proof of concept using forward modeled cases and actual field applications in sandstone and carbonate reservoirs are performed to examine the theoretical and the practical applications of the methodology. Excellent results are obtained and discussed.

Published: July 2020

ZusammenfassungIn realen Unterrichtssituationen diagnostizieren Lehrkräfte aufgrund enormer Interaktionsdichten sowie hoch komplexer Unterrichtssituationen unter psychischer Anspannung wie Stress. Durch Stress können kognitive Kapazitäten gebunden werden, was Prozesse beim Diagnostizieren, wie die Wahrnehmung und die Interpretation von Aufgabenschwierigkeiten, beeinträchtigen kann.Die vorliegende Studie untersuchte in einem experimentellen Design den Einfluss von Stress auf Wahrnehmungs- und Interpretationsprozesse beim diagnostischen Urteilen. Hierzu schätztenN = 64 Mathematiklehramtsstudierende die Schwierigkeit von acht mathematischen Textaufgaben im Bereich von Brüchen ein. Die Wahrnehmungsprozesse wurden mithilfe von Blickbewegungen durch die Methode des Eye Trackings erhoben und anhand ausgewählter globaler Maße (Dauer des Blickpfades, Fixationsdauer, Anzahl der Fixationen ab 250 ms und Sakkadenamplitude) analysiert. In Kombination mit Verbalprotokollen wurden die Interpretationsprozesse ausgewertet. Anhand der Analyse von Cortisolwerten aus Speichelproben während des Diagnostizierens wurde das Stressniveau der Teilnehmenden objektiv erfasst. Aufgrund der Bindung kognitiver Kapazitäten durch Stress wurden Veränderungen sowohl in den Wahrnehmungs- als auch in den Interpretationsprozessen erwartet. Die Ergebnisse der Blickbewegungsanalysen zeigten eine kürzere Blickpfaddauer, eine kürzere Fixationsdauer sowie eine geringere Anzahl an Fixationen mit einer Dauer ab 250 ms bei Teilnehmenden unter Stresserleben. Die Verbalprotokolle unterschieden sich qualitativ zwischen den Gruppen. Die veränderten Maße können als Indikatoren der veränderten Wahrnehmungs- und Interpretationsprozesse der Experimentalgruppe interpretiert werden.Die Studie gibt erste Hinweise auf den Einfluss von Stress auf diagnostische Prozesse im anwendungsbezogenen Schulkontext.

Published: July 2020

Background and Objectives:
There are some studies on the association between attention deficit and hyperactivity disorder (ADHD) and the risk of eating disorders (ED). Only few have examined the risk of ED among children and adolescents with ADHD. Previous research which included subjects with ADHD with other comorbidities used inadequate controls and did not focus on the type of ADHD or the role of pharmacological treatment.

Methods:
This matched cohort study was conducted in the Child/Adolescents Psychiatry Unit (CAPU), Bahrain. Using the CAPU diagnostic frameworks, 70 subjects with ADHD were recruited and matched with their corresponding age- and sex- healthy controls at 1:2 ratio (70 cases:140 controls). The participants were children or adolescents aged between 8 and 19 years old. A brief interview was used to collect socio-demographic information and anthropometrics. The risk of ED was estimated using the eating attitude test −26 (EAT-2). Data were analyzed using cohort analysis.

Results:
A total of 31.43% of the subjects with ADHD were screened using EAT-26 and found to be ‘at risk’ for ED, compared to 12.14% of the controls (OR 3.31, 95% CI 1.62–6.78). The prevalence of ED among female cases with ADHD was slightly higher than males (33.33% and 30.77%, respectively). Body weight or body mass index was a statistically significant explanatory factor for the risk of ED.

Conclusions:
The present study shows that children and adolescents with ADHD have a three-fold increased risk of ED compared to healthy controls. This research raised the recommendation that children and adolescents with ADHD should be screened for disordered eating patterns.

Abstract
Diet has a major influence on the composition and metabolic output of the gut microbiome. Higher-protein diets are often recommended for older consumers; however, the effect of high-protein diets on the gut microbiota and faecal volatile organic compounds (VOC) of elderly participants is unknown. The purpose of the study was to establish if the faecal microbiota composition and VOC in older men are different after a diet containing the recommended dietary intake (RDA) of protein compared with a diet containing twice the RDA (2RDA). Healthy males (74⋅2 (sd 3⋅6) years; n 28) were randomised to consume the RDA of protein (0⋅8 g protein/kg body weight per d) or 2RDA, for 10 weeks. Dietary protein was provided via whole foods rather than supplementation or fortification. The diets were matched for dietary fibre from fruit and vegetables. Faecal samples were collected pre- and post-intervention for microbiota profiling by 16S ribosomal RNA amplicon sequencing and VOC analysis by head space/solid-phase microextraction/GC-MS. After correcting for multiple comparisons, no significant differences in the abundance of faecal microbiota or VOC associated with protein fermentation were evident between the RDA and 2RDA diets. Therefore, in the present study, a twofold difference in dietary protein intake did not alter gut microbiota or VOC indicative of altered protein fermentation.
Azeris and Muslim Ajarians in Georgia: The Swing between Tolerance and Alienation
Authors: Kahraman Alter 
Published: July 2020

AbstractThis article focuses on two Muslim groups, Azeris and Muslim Ajarians, who are differently perceived and treated in post-Soviet Georgia. Georgian ethno-religious nationalism bases Georgianness on an ethnic affiliation to Kartvelian roots and religious adherence to Georgian Orthodoxy, and determines one’s level of inclusion in the nation accordingly; those who do not fulfill these criteria, such as Azeris, are excluded from the nation. Muslim Ajarians, despite being Georgians, also face exclusion from Georgian identity. Based on the concept of ethnodoxy, which is defined as linking of “a group’s ethnic identity to its dominant religion,” this article argues that Muslim Ajarians, who are Georgian Muslims, an unaccepted category in Georgia, receive differential treatment by their Christian fellows, whereas recognition of the religion and ethnicity of Azeris is a factor that comparatively diminishes the pressure on the community. This research demonstrates that the visibility of Muslim Ajarians’ religious practices in the public space and the construction of places of worship is less tolerated than in the case of Azeris, who have no means of becoming “proper Georgians.” The findings of fieldwork in Georgia manifested that, although minorities have various problems in Georgia, Muslim Ajarians are subjected to more differential treatment than Azeris.
CYCLIC BRANCHED COVERINGS OF BRIESKORN SPHERES BOUNDING ACYCLIC 4-MANIFOLDS
Authors: ANVARI NIMA , HAMBLETON IAN 
Published: July 2020

AbstractWe show that standard cyclic actions on Brieskorn homology 3-spheres with non-empty fixed set do not extend smoothly to any contractible smooth 4-manifold it may bound. The quotient of any such extension would be an acyclic 4-manifold with boundary a related Brieskorn homology sphere. We briefly discuss well-known invariants of homology spheres that obstruct acyclic bounding 4-manifolds and then use a method based on equivariant Yang–Mills moduli spaces to rule out extensions of the actions.
Dementia-Friendly Neighbourhoods in Canada: A Carer Perspective
Authors: Silverman Marjorie 
Published: July 2020

ABSTRACTBased on findings from a study examining the lived experiences of dementia carers in their neighbourhoods, this article offers a vision of what dementia-friendly communities could look like from a carer perspective and in a Canadian context. Twelve carers in Ottawa and its surrounding regions were interviewed using a combination of social network maps, mobile interviews, and participant-driven photography. The findings, organized according to the categories “relationships”, “places”, and “everyday practices”, reveal that many of the carers’ choices regarding businesses, services, home location, outings, and everyday practices, are based on a desire to maintain social connections and social citizenship. The article concludes with recommendations for consideration in the planning of dementia-friendly neighbourhood initiatives.
Role of pulsed-xenon ultraviolet light in reducing healthcare-associated infections: a systematic review and meta-analysis
Authors: Dong Zhenhong , Zhou Na , Liu Guijuan , Zhao Li 
Published: July 2020

Abstract
Pulsed-xenon-ultraviolet light (PX-UVL) is increasingly used as a supplemental disinfection method in healthcare settings. We undertook a systematic search of the literature through several databases and conducted a meta-analysis to evaluate the efficacy of PX-UVL in reducing healthcare-associated infections. Eleven studies were included in the systematic review and nine in the meta-analysis. Pooled analysis of seven studies with before-after data indicated a statistically significant reduction of Clostridium difficile infection (CDI) rates with the use of the PX-UVL (incidence rate ratio (IRR): 0.73, 95% CI 0.57–0.94, I2 = 72%, P = 0.01), and four studies reported a reduction of risk of methicillin-resistant Staphylococcus aureus (MRSA) infections (IRR: 0.79, 95% CI 0.64–0.98, I2 = 35%, P = 0.03). However, a further four trials found no significant reduction in vancomycin-resistant enterococci (VRE) infection rates (IRR: 0.80, 95% CI 0.63–1.01, I2 = 60%, P = 0.06). The results for CDI and MRSA proved unstable on sensitivity analysis. Meta-regression analysis did not demonstrate any influence of study duration or intervention duration on CDI rates. We conclude that the use of PX-UVL, in addition to standard disinfection protocols, may help to reduce the incidence of CDI and MRSA but not VRE infection rates. However, the quality of evidence is not high, with unstable results and wide confidence intervals, and further high-quality studies are required to supplement the current evidence.
Phonological variation and change in the regional French of Alsace: Supralocalization, age, gender and the urban–rural dichotomy
Authors: Boughton Zoë , Pipe Katharine 
Published: July 2020

ABSTRACTThis article examines patterns of variation and change in the phonology of the regional French of Alsace, within an overarching framework of regional dialect levelling (Kerswill, 2003) in the French of France. Data are drawn from an original corpus gathered in Strasbourg and a small village in a rural area of the Bas-Rhin. We analyse two well-known regional features in spontaneous speech: (h), the variable realisation of initial [h], and (ʒ), the non-assimilatory devoicing of /ʒ/. We focus on the effect on the variation observed of the major extra-linguistic variables of age, gender and social class as well as urban or rural community. While the results for class and location follow expected patterns, whereby working-class and rural speakers show higher rates of traditional non-standard variants, the principal observation is the decline and, in the case of (ʒ), apparent loss of such features. We thus provide new evidence in support of supralocalization, not only in the urban context but also in the rural location. The results for gender are however less clear-cut: there is an interaction with age, class and location, and disruption of the usual pattern of female-led adoption of supralocal norms.
Information quality, adoption of climate-smart varieties and their economic impact in flood-risk areas

Published: July 2020

AbstractWeather extremes which are accelerated by changing climate greatly decrease agricultural productivity, resulting in severe economic losses and losses of livelihood of the poorest marginal communities. The adoption of stress-tolerant rice varieties (STRVs) is recommended as a best technology fix for risk adaptation. Although STRVs provide better outcomes with no yield penalty, farmers' decisions to adopt new STRVs are influenced by a multitude of factors, most importantly information exposure. We used a sequential logit model to analyze the impact of information access and information quality on adoption decisions regarding STRVs in flood-risk areas. Over the years, we found that STRVs adoption has become scale neutral, but adopters have significantly higher access to information. The estimates showed that 48 per cent of the farmers having access to information decided to adopt STRVs. When information reaches 50 per cent of the rice farmers in flood-prone areas, the estimated additional annual income is US$235 million.
