Study and definition of project attributes for selection of testing techniques for concurrent software
Authors: de Oliveira Santos Italo , do Rocio Senger de Souza Simone
Published: September 2019

[Context:] The choice of testing technique to be adopted in a software testing project persists based on the tester’s knowledge and often does not consider all of the testing techniques available in the industry or academia. In a previous project of the research group, a framework was defined to support the systematic selection of concurrent software testing techniques. Therefore, a characterization scheme was proposed and implemented in the SeleCTT tool, which is composed of a set of attributes that considers characteristics of concurrent programs and they are used to calculate which of these attributes are suitable to guide the selection of testing techniques for a particular software project. [Objective:] The selection of the testing technique at each stage of a software’s life cycle depends on many factors, such as resources, schedule, cost of the project, among other attributes. This work will extend the previously defined attributes, taking into account other characteristics that may be considered, for example, information from previous similar projects. Considering that the testing techniques are complementary, another goal is to allow a set of testing techniques to be selected and not just one. [Methodology:] To achieve this goal, a systematic mapping study was conducted to identify and analyze papers that represent the current state of the literature about testing techniques selection. Moreover, we surveyed software testing practices carried in Brazil software companies. The survey identified the testing practices in Brazilian industries, for the purpose of knowing and having an overview on the latest testing techniques, tools and metrics used, the challenges faced by testers and the selection testing technique process. [Results and Conclusions:] With this study, it is expected to specify project attributes that can be used to improve the existing recommendation system in the SeleCTT tool and propose ways of combining testing techniques, contributing to industry and academia, and bring insights on the context of testing techniques selection.

Comparative Study on the Friction Property of Bearing Steel Modified Bygraphite/MoS2 Composite Coating and Manganese Phosphate Coating
Authors: ZANG Libin , CHEN Yong , RAN Lixin , ZHENG Yang , LI Kai , JU Dongying
Published: September 2019

Surface modification is an important method to improve the contact fatigue life of transmission parts. The preparation of high performance coating with good tribological properties on the gears and bearings has become the research trends. This paper presents graphite/MoS2 composite spray and manganese phosphate conversion coating prepared on the AISI52100 steel surface and investigates their anti-fatigue mechanism. The tribological properties of the modified layers were studied using a SRV-IV multifunctional friction and wear tester. The microstructure and interfacial components of the coating and wear surfaces were analyzed by SEM and EDS, respectively. The surface morphology and phase composition of the coating were evaluated through laser 3D microscopy and XRD analyses, respectively. Both modified layers showed good anti-friction and anti-wear properties. The friction coefficients of the surfaces modified by manganese phosphate coating and graphite/MoS2 decreased by 7 % and 14 %, respectively, and the corresponding extreme pressure properties increased by 11 % and 55 %, respectively. But the mechanism of anti-fatigue wear and the corresponding interfacial phenomena of the surface modification of the graphite/MoS2 composite spraying layer is different from those of manganese phosphate coating. The hard-ceramic particles with graphite and MoS2 are sprayed on the substrate to obtain the surface hardening layer, resulting in higher wear resistance. The graphite and MoS2 modified layer can greatly reduce the friction coefficient and improve the lubrication performance on the surface. Manganese phosphate coating serves as a chemical soft coating and is filled with rough corrugated caused by surface processing, which induces an ideal meshing surface after initial friction phase. The obtained hole-shaped structure and "infiltration" role contribute to the storage of lubricants and thus improves the lubrication performance.

Published: September 2019

The research is focused on a novel aluminum and copper-containing heat-resistant steel. The steel was designed by the material performance simulation software JmatPro, performed high-temperature oxidation tests at 650 °C and 700 °C atmospheric conditions, and analyzed the high-temperature oxidation processes and its mechanisms.The phase transtions and surface morphology of the oxide films were studied using X-ray diffraction (XRD), electron microscopy (SEM) and energy-dispersive X-ray spectroscopy (EDS). The results showed that the equilibrium phase of the test steel is composed of γ phase and δ phase at 1050 °C and tranforms to tempered martensite and δ-Fe mixed structure after heat treatment. The preferential oxidation of Fe and Cr and the internal oxidation of Al occurred during the high temperature oxidation of the test steel. The oxide films were formed with various shape and weak bonding properties after high-temperature oxidation at 650℃. To the contrary, the oxide films more regular and evenly distributed, and has a certain protective effect after high-temperature oxidation at 700 ℃. The oxide films were divided into two layers, Fe2O3 is main element in the outer layer, the inner layer is mainly consisting the oxide of Cr. However, the addition of Cu element can promote the diffusion of Al and Si elements, which is beneficial to the formation of Al2O3 and SiO2 protective oxide films and excellent in high temperature oxidation resistance.

Authors: ZHANG Xiaolian , YANG Chubin , LIU Hongxia , PENG Guanghuai
Published: September 2019

In the present paper, an Al rod as liquid cathode was added into the SmF3-LiF-Sm2O3 molten salt system and subsequently the Al-Sm alloy was prepared by the liquid cathode electrolysis method. The effects of electrolysis temperature, cathode current density and electrolyte composition on the current efficiency were studied. The results demonstrated that the maximum content of Sm in the Al-Sm interalloy could reach up to 32.8 wt.%, whereas the alloy was mainly composed of the Al substrate, Al4Sm and Al3Sm phases. The current efficiency increased first subsequently decreased as the electrolysis temperature and cathode current density increased. Simultaneously, the electrolyte composition had a high impact on the current efficiency. When the mass ratio of SmF3and LiF was 4, the current efficiency was 62.8 %.
Data on Evaluation of the Corrosion Inhibition Effect of L-alpha-aminoisocaproate on High Carbon Steel Corrosion in Dilute Acid Media
Authors: LOTO Roland , LOTO Cleophas
Published: September 2019

Corrosion inhibition performance of l-alpha-aminoisocaproate on high carbon steel in 1 M HCl solution has been studied by weight loss measurement, open circuit potential measurement, optical microscopy and ATF-FTIR spectral analysis. The results showed the inhibition performance of l-alpha-aminoisocaproate is time dependent attaining an optimal value of 85.88 % at 5.63 % l-alpha-aminoisocaproate concentration (highest concentration) after 288 h of exposure. The corrosion potential plots of the high carbon steel at 0.91 % (lowest concentration) and 5.63 % l-alpha-aminoisocaproate concentration were more electropositive than the plots at 0% l-alpha-aminoisocaproate concentration due to the effective inhibition performance of l-alpha-aminoisocaproate in counteracting the oxidation of the carbon steel in the presence of chloride anions. Identified functional groups of alcohols, phenols, primary and secondary amines and amides, carboxylic acids, alkynes, aromatics, alkenes and alkanes consisting of O–H stretch, free hydroxyl, H–bonded, N–H stretch, –C(triple bond)C–H: C–H stretch, C–H stretch and =C–H stretch bonds where responsible for the corrosion inhibition. The optical morphology of the carbon steel after 7200 s of exposure in the acid solution without l-alpha-aminoisocaproate was severely corroded in contrast to the morphology of the steel in the presence of l-alpha-aminoisocaproate which underwent minor deterioration due to the time dependent action of the inhibitor.

Published: September 2019

The goal of this investigation was to find out influence of heat treatment at low temperatures on the Lithuanian spruce wood bending strength. The influence of heating temperature and duration on the strength of spruce wood during statical bending has been investigated. The tests were carried out using samples with size of 20 ´ 20 mm in cross-section and 300 mm in length. Density of samples varied from 460 up to 500 kg/m3. The samples were heated at conditions close to those used during manufacturing process. Temperature was equal to T = 60, 80, 100 and 120 °C and heating duration was selected t = 24, 48, 72 and 96hours. The obtained results reveal that heating at relatively low temperatures, influences the strength of the spruce wood during bending. After the increase of both drying temperature and duration decrease of bending strength was found. The longer heating duration at lower temperatures results in less strength changes compare to those heated at higher temperatures for shorter duration. It was found that heating temperature is more significant technological parameter for spruce wood bending strength compare to those of heating duration.

Published: September 2019

Welche Bedeutung haben 30 Jahre nach dem politischen Umbruch in der DDR deren Geschichte, Gesellschaftsform und insbesondere die Ausprägungen von Fürsorge und Erziehung für die gegenwärtige Lehre und Forschung in der Sozialen Arbeit? Ist das bereits »lange her« und spielt »eh keine Rolle« mehr - wie auch von einzelnen Lehrenden Sozialer Arbeit an ostdeutschen Hochschulen geäußert wird - oder ist es notwendig, genauer hinzusehen, nachzufragen und die eigene Position zu reflektieren? Und spielt es eine Rolle, welche Zugehörigkeit wir als Lehrende mitbringen und aus welcher Standortgebundenheit wir sprechen? Der folgende Text ist als Kommentar geschrieben, er ist als eine Art Fragensammlung gedacht und als Aufschlag für eine Debatte, die wir m. E. auch in der Sozialen Arbeit beginnen sollten - in allen Regionen des Landes.
Frühes Eingreifen bei psychischer Arbeitsunfähigkeit als ambivalente Strategie
Authors: Gonon Anna
Published: September 2019

Angesichts steigender Zahlen psychisch bedingter Arbeitsunfähigkeit lautet die sozialpolitische Empfehlung, auf Frühintervention am Arbeitsplatz zu setzen. Ein möglichst frühes Eingreifen soll verhindern, dass psychische Gesundheitsprobleme ernster werden und zum Verlust der Arbeitsstelle führen. Inhaltlich ist das Prinzip des frühen Eingreifens jedoch unbestimmt. Der Beitrag untersucht anhand einer qualitativen Studie in zwei Versicherungs- und einem Industrieunternehmen in der Schweiz, wie betriebliche Akteure das Prinzip des frühen Eingreifens in der Wiedereingliederung psychisch erkrankter Beschäftigter umsetzen und welche Rolle es in ihren Strategien spielt. Die analysierten Praktiken der Frühintervention zielen darauf ab, die Akzeptanz für das eingeschränkte Arbeitsvermögen der Betroffenen zu fördern. Die Akteure blenden betriebliche Faktoren, die zu psychischen Belastungen beitragen, jedoch tendenziell aus. Frühe Interventionen unterstützen die Beschäftigten dabei, sich den Leistungsanforderungen optimal anzupassen, werden aber nicht darauf ausgerichtet, gesundheitliche Risiken am Arbeitsplatz frühzeitig zu beseitigen.
Das Recht der Berufsgruppen in der medizinischen Rehabilitation
Authors: Goldbach Christiane
Published: September 2019

This work deals with the “law of professionals” in the medical rehabilitation process in Germany. The wide-spread assumption that medical rehabilitation is conducted by cross-professional teams only under the supervision of a medical doctor is critically examined. The aim is to investigate the required conditions under which the different occupational groups should be entitled to be regarded as care providers within the social law system. In this context, the concept of medical rehabilitation is thoroughly discussed and specified. The main legal sources to be analysed are social law (especially SGB IX, SGB V, SGB VI), professional law [direktes Berufsrecht] for selected occupational groups and constitutional law. Existing tensions between the legal regulations are examined. The results show that the law considers medical rehabilitation an occupational field which covers the entirety of the so-called “Heilberufe” [health professions] and is complemented by the work of additional occupational groups.

Business Judgment Rule und Insolvenzverwalterhaftung
Authors: Resch Sarah-Maria
Published: September 2019

The codification of the so-called business judgement rule in section 93, para. 1, sentence 2 of the German Stock Corporation Act was intended to create a liability-free zone in the field of qualified business decisions for board members of a stock corporation. Especially since the continuation of business during insolvency proceedings has been made possible, an insolvency administrator steps into the position of a managing director and, as such, also has to make business decisions.
This work examines whether and to what extent the business judgement rule in the German Stock Corporation Act is also applicable to the liability of insolvency administrators, which particularities their constituent elements have in comparison to stock corporation law and in which concrete decision-making situations an insolvency administrator can make use of the business judgement rule. The work closes by suggesting suitable wording for an insolvency business judgement rule.

Published: September 2019

O objetivo desse estudo foi analisar de que forma os professores de Educação Física em diferentes períodos de experiência profissional utilizam o componente avaliação. Trata-se de um estudo de caso na RMEPEL com quatro professores com um, 13, 21 e 31 anos de docência. Depreendemos que no início da carreira a avaliação parte de um plano mais informal, passando pela busca da ocorrência da apropriação do aprendizado pelo alunado e reflexão dos mesmos e no fim da carreira houve prevalência de aspectos formais na avaliação. A nota apresentou um “valor de troca” entre professorado e alunado independentemente da experiência docente.
Interventions for reducing suicide risk in cancer patients: A literature review
Authors: Bulotiene Giedre , Pociute Kamile
Published: September 2019

The suicide risk of people diagnosed with cancer is two times higher than the general population. The number of cases of diagnosed cancer is estimated to rise by 70% over the next two decades. Evidence-based prevention strategies are necessary to protect this vulnerable group of individuals. The purpose of this review was to find out the risk factors of suicide and which types of interventions can serve as prevention strategies. Psychosocial interventions, pharmacotherapy and physical activity can play a preventive role in reducing psychosocial and physical risk factors, such as mental disorders, poor social support, poor performance status and pain. Further research is needed to develop effective suicide prevention strategies for cancer patients.
Voir et montrer la mort animale
Authors: Givre Olivier , Franck Alice , Gardin Jean
Published: September 2019

Les régimes de visibilité et d’invisibilisation, du cacher et du montrer, sont particulièrement significatifs en matière de mort animale. S’il est fréquent de considérer l’abattage comme une ellipse entre l’animal et la viande, des pratiques comme le sacrifice ou la chasse se présentent à l’inverse comme nécessitant de rendre la mise à mort visible et attestable. Au statut de morts « bonnes à voir » ou « à cacher » s’ajoute aujourd’hui la question du traitement médiatique de la mort des animaux, dont les images possèdent un impact puissant, à l’instar des vidéos des mouvements animalistes et des reportages télévisés. L’expérience de la mort animale affecte aussi la chercheuse ou le chercheur, amené lui-même à interroger son propre rapport au fait de voir et montrer la mort animale. Au croisement de réflexions issues de nos pratiques scientifiques et d’exemples tirés d’une production audiovisuelle, littéraire et artistique foisonnante sur ce thème, nous nous interrogeons sur les différents régimes d’image des morts animales, sur les rapports entre le visible et l’invisible, le montrable et le caché.
Les représentations des chasseuses dans des médias contemporains. Une analyse exploratoire
Authors: Lew Viviane
Published: September 2019

L’implication des femmes dans la chasse fait l’objet de polémiques dans les médias contemporains. L’analyse qualitative d’articles de presse et de magazines parus entre 2013 et 2017, d’entrevues et de témoignages publiés sur l’expérience des chasseuses, et des commentaires du grand public permet d’explorer la diversité des représentations quant aux motivations sous-jacentes à l’activité cynégétique, les stratégies de chasse, les réactions face à la mort des animaux, le rapport à la nature et la protection de la faune. Le corpus met aussi en évidence les réactions contrastées et intenses du grand public quant à la participation des femmes à la chasse (propos sexistes à leur égard ou défense de leurs droits, questionnements sur leur santé mentale, enjeux éthiques, etc.), de même que les préjugés et stéréotypes soulevés dans ces discours qui rejoignent ceux rapportés à l’encontre des femmes s’engageant dans des métiers traditionnellement masculins.
Le korban sera-t-il restauré dans le Troisième Temple? Débats contemporains sur le sacrifice biblique
Authors: Lévy Joseph J.
Published: September 2019

Le sacrifice animal constitue l’un des rituels courants dans plusieurs contextes socioculturels, en particulier dans les religions antiques, tel le culte sacrificiel biblique (korban) disparu avec la destruction du Second Temple et remplacé par la prière. Néanmoins, les discours religieux autour de cette pratique se sont poursuivis depuis l’Antiquité avec des commentaires et des prises de position quant à la restauration de ces rituels avec la reconstruction éventuelle du Troisième Temple de Jérusalem. À partir de l’analyse de divers textes duxixesiècle et contemporains (articles de revues, ouvrages religieux, transcriptions de sermons, blogues), cet article dégage les constructions du sacrifice et ses interprétations passées et actuelles, les positions divergentes sur la restauration complète ou partielle ou sur l’annulation de ce rituel et les types d’arguments associés à chacune d’entre elles.
Se retirer pour lire : variations sur l’expérience sociale de la solitude
Authors: Roselli Mariangela
Published: September 2019

Dans plusieurs enquêtes ethnographiques réalisées sur les manières de lire contemporaines, un élément inattendu a émergé dans les témoignages recueillis : la condition de solitude, volontairement et minutieusement aménagée par les personnes qui aiment lire. Bien que ces lecteurs ne se considèrent pas eux-mêmes comme des « solitaires », ils insistent particulièrement sur le retrait comme conquête sur et contre leur entourage. Cette solitude choisie semble relever d’un quasi-engagement tant elle est arrachée de la trame sociale dense dans laquelle ils vivent au quotidien. Pour ces lecteurs et lectrices, c’est le retrait pour lire qui a une signification particulière. Pour les femmes et les hommes interrogés, l’éloignement du groupe se construit à l’articulation des rapports sociaux d’âge et des rapports sociaux de genre : c’est en effet à l’intersection de figures aussi contradictoires, contrastées et mutuellement exclusives que celle de l’enfant-qui-lit, de l’homme-qui-lit et de la femme-qui-lit que prend sens leur retrait pour lire.
Quand Minette rentre dans la parenté
Authors: Michon-Chassaing Sophie , Gonzalez Georges
Published: September 2019

Cadre de la recherche : Prépondérant au sein de la sphère familiale, l’animal peut se révéler un facilitateur au sein d’une formation traitant de filiations. Un lien est établi entre l’évolution de la structure familiale au sein de laquelle l’individuation des membres s’affermit et une revalorisation de l’animal en tant qu’individu à part entière au sein de la famille contemporaine.

Objectifs : Cet article montre que si l’implication dans la réalisation d’un génogramme qui oblige une remémoration de son histoire familiale peut susciter des résistances, la convocation psychique d’un lien avec un animal lié à cette histoire agit comme levier sur les résistances.

Méthodologie : Des observations cliniques réparties sur trois années sont effectuées au sein de 20 groupes de 12 personnes lors d’une formation en psychogénéalogie dans un centre de formation de travail social.

Résultats : Une consigne de base trop impliquante pour soi, mais à laquelle l’animal fait perdre son signifiant négatif, suggère l’hypothèse qu'un élargissement de la consigne au non-humain ouvre au dépassement de soi en convoquant un attachement sécurisant.

Conclusions : Une remémoration de l’inscription de l’animal dans la sphère familiale favorise la construction identitaire de la personne concernée. Ce retour sur soi, en inscrivant la famille en communauté d’affects, agit comme opérateur de résilience vis-à-vis d’un contenu généalogique abimé par des blessures du passé.

Contribution : Le groupe familial contemporain souffre de nombreuses tensions, entre fragilité et ancrage par exemple rencontré fréquemment dans les situations de divorce. Pour autant, la parenté reste une ressource pour la construction de soi. Les effets positifs de l’inscription de l’animal lors de séances de psychogénéalogie s’appuyant sur une représentation de la constellation familiale révèlent qu’à l’instar de n’importe quelle personne proche, cette inscription participe à la construction de soi.
L’expérience de pères ayant des difficultés d’accès à leur enfant après une séparation
Authors: Deslauriers Jean-Martin , Dubeau Diane
Published: September 2019

Cadre de la recherche : La reconnaissance par la communauté scientifique d’un engagement accru des pères auprès de leurs enfants ainsi qu’un partage des responsabilités entre les parents devrait se traduire par un maintien de la présence des pères auprès de leurs enfants à la suite d’une séparation conjugale. Si, en principe, les parents sont égaux devant la loi en ce qui a trait à leur droit d’exercice respectif de l’autorité parentale, on observe cependant des écarts dans le partage de la garde entre les mères et les pères.

Objectifs : Cette recherche a pour but d’identifier les facteurs qui contribuent à diminuer ou rompre l’accès de pères à leur enfant à la suite de leur séparation conjugale.

Méthodologie : Les données de recherche sont tirées d’entrevues semi-dirigées réalisées auprès de quatorze pères séparés ayant des difficultés d’accès à leur enfant et qui ont porté sur leur situation de vie afin de relever les facteurs et dynamiques qui expliquent la situation en partant de leur point de vue.

Résultats : Contrairement à plusieurs recherches qui attribuent ces contacts moins fréquents du père séparé avec son enfant à un désengagement de sa part, une multitude de facteurs autres que les facteurs individuels ont été identifiés.

Conclusions : Les conclusions de la recherche mettent en lumière plusieurs facteurs relevant de différents niveaux écosystémiques qui se cumulent, fragilisant ainsi la relation avec l’enfant.

Contribution : Cette recherche offre une perspective multifactorielle permettant de cerner la complexité de ce phénomène et des processus par lesquels il se construit. Elle documente un phénomène méconnu, celui des pères qui souhaitent cultiver ces liens, mais qui sont confrontés à des difficultés d’accès à leur enfant.
Le bras de fer de la conciliation vie professionnelle-responsabilités de soins des aidantes en emploi : entre équilibre et décrochage
Authors: Gagnon Mélanie , Beaudry Catherine
Published: September 2019

Cadre de la recherche : Cet article rend compte de la façon dont des femmes proches aidantes, pivot des solidarités familiales, vivent la conciliation entre leur vie professionnelle et leurs responsabilités de soins.

Objectifs : Comprendre les besoins des aidantes en matière de conciliation travail rémunéré et responsabilités de soins, de même que la manière dont elles vivent le conflit entre les divers rôles qu’elles assument.

Méthodologie : Les besoins des aidants ont été capturés de manière qualitative par l’entremise de 42 entretiens semi-dirigés menés en profondeur avec des femmes proches aidantes.

Résultats : Les solidarités familiales reposent en majeure partie sur les épaules des aidantes. La façon dont elles composent avec leurs responsabilités d’aidantes et leur vie professionnelle fait ressortir des points de divergence, mais aussi des similitudes au regard des difficultés qu’elles rencontrent.

Conclusions : Les employeurs devraient mettre en place des programmes de conciliation généraux, flexibles et tout en tenant compte des besoins des proches aidants et de leur situation singulière et évolutive afin d’éviter les pénalités professionnelles, les inégalités de genre et de permettre une réelle conciliation de tous les temps sociaux peu importe les parcours de vie.

Contribution : Mettre en lumière que les aidantes en emploi vivent différemment la conciliation de leur rôle d’aidante avec leur vie professionnelle par la proposition d’une typologie d’aidantes en emploi.
The relationships between bilingual learning, willingness to study abroad and convergent creativity
Authors: Zhao Yuan , Yuan Yuan , Shen Wangbing , Zhu Chuanlin , Liu Dianzhi
Published: September 2019

Convergent creativity is a form of creative thinking that uses existing knowledge or traditional methods to analyze available information and generate an appropriate solution. The differences in the performance of participants in convergent creativity caused by bilingual learning is a popular research area in creativity. A final sample of 68 participants was asked to complete the remote associates test (RAT). The results indicate that a moderate positive correlation exists between bilingual learning and convergent creativity. Students who want to study abroad perform better on the RAT than those who do not, and this effect is mediated by second language proficiency. These findings suggest that improving students’ English proficiency and increasing their opportunities to study abroad may be effective ways to promoting convergent creativity.
Transcriptome association studies of neuropsychiatric traits in African Americans implicate PRMT7 in schizophrenia
Authors: Fiorica Peter N. , Wheeler Heather E.
Published: September 2019

In the past 15 years, genome-wide association studies (GWAS) have provided novel insight into the genetic architecture of various complex traits; however, this insight has been primarily focused on populations of European descent. This emphasis on European populations has led to individuals of recent African descent being grossly underrepresented in the study of genetics. With African Americans making up less than 2% of participants in neuropsychiatric GWAS, this discrepancy is magnified in diseases such as schizophrenia and bipolar disorder. In this study, we performed GWAS and the gene-based association method PrediXcan for schizophrenia (n = 2,256) and bipolar disorder (n = 1,019) in African American cohorts. In our PrediXcan analyses, we identified PRMT7 (P = 5.5 × 10−6, local false sign rate = 0.12) as significantly associated with schizophrenia following an adaptive shrinkage multiple testing adjustment. This association with schizophrenia was confirmed in the much larger, predominantly European, Psychiatric Genomics Consortium. In addition to the PRMT7 association with schizophrenia, we identified rs10168049 (P = 1.0 × 10−6) as a potential candidate locus for bipolar disorder with highly divergent allele frequencies across populations, highlighting the need for diversity in genetic studies.

Water is an important medium for many activities including water for consumptive and non-consumptive purposes. Lack of water quality and quantity does not only hampers socio-economic development but affects agricultural productivity, sustainable development, sanitation, health, industrial development and the ecosystem. The advent of climate change is known to affect water flow, increases dry season spells and drought, and influences reservoirs or deep groundwater wells thus worsening the precarious water situation in Africa.  About 1.7 billion of the world population lives in water scarce regions and this is projected to grow to about 300% or 5 billion by 2025 especially in Africa.  In Ghana, population growth, pollution of river bodies, high evapotranspiration, erratic rainfall pattern and environmental degradation among others have affected water availability and use.  These challenges will therefore require a deliberate water harvesting, integrated water management and conservation, water use efficiency and capacity building to withstand the dwindling trend of water resources in the country. This paper therefore seeks to inform policy makers, stakeholders, institutions responsible for water resources management among others to consider water harvesting as a potential solution to the many challenges including water shortages, floods, and land degradation. The article was carried out through extensive review of literature, official reports and policy documents. It shows the need to adopt appropriate techniques for rainwater harvesting to address the perennial water scarcity in the country.

O paradoxo da submissão como mecanismo libertário nas práticas corporais
Authors: Costa Eliza Mara Lozano
Published: September 2019

Pretendemos compreender como é possível que determinadas práticas corporais, tais como as práticas somáticas, sejam capazes de transformar modos de pensarmos nossa própria subjetividade (que é também socialmente construída) e, consequentemente, nossas maneiras de ser e de agir no mundo. Nosso foco aqui é a relação estabelecida entre instrutor e praticante, entendida aqui, necessariamente, como uma relação de poder. Partimos da afirmação de que se a dança e o movimento pode ser uma descoberta de si e uma possibilidade de liberdade individual, isso pode ser entendido como um resultado de uma relação social de dominação. Se isso está correto, uma prática corporal que se pretende libertadora só se realizaria, paradoxalmente, porque baseada numa relação de submissão. Sabemos que as práticas somáticas partem do respeito aos limites e à expressividade de cada um. Porém, o praticante, ao entrar na aula, aceita entrar em situações que, não raro, poderá sentir vergonha, humilhação, ou mesmo dor (o que muitas vezes acontece, em detrimento à proposta) mas que, em seguida, talvez sinta-se livre, solto e aberto para mudar-se. Procuramos aqui discutir esse paradoxo e, por último, pensá-lo no contexto atual da chamada sociedade do desempenho; na qual nos vemos capazes e livres para tudo empreender, tudo poder, mas que, na prática, somos apenas sobreviventes de uma sociedade do cansaço, ventre de depressões e doenças psíquicas, pois não seríamos capazes de perceber e negar a saturação, os excessos dessa sociedade.

Assim, a potencialidade das práticas somáticas seriam resultado, a nosso ver, de um intervalo de "não liberdade", de submissão contratual, de permissão a um "poder", o qual nos permitiria uma nova percepção dessa saturação e a abertura, então, para novas possibilidades de ser.
Emotion regulation mediates relationships between mindfulness facets and aggression dimensions

Recent years have witnessed an increase of research on socio‐affective factors that can explain individual differences in aggressive tendencies across community and offender populations. Specifically, mindfulness and emotion regulation have emerged as important factors, which could also constitute important prevention and treatment targets. Yet, recent studies have advanced the possibility that mindfulness may also have a “dark” side, being associated with increased levels of aggression‐related variables, especially when accounting for the variance associated with emotion regulation. The present study sought to elucidate relationships among mindfulness, emotion regulation, and aggression dimensions (i.e., verbal and physical aggression, anger, and hostility) across violent offender (N = 397) and community (N = 324) samples. Results revealed expected associations between both mindfulness and emotion regulation and aggression dimensions, such that greater impairments in mindfulness and emotion regulation were related to increased levels of aggression across samples. Further, analyses of indirect effects revealed that a latent emotion dysregulation factor accounted for (i.e., mediated) relationships between mindfulness facets and aggression dimensions in both samples. Previously reported positive associations between the residual variance in mindfulness scales (i.e., controlling for emotion regulation) and aggression‐related variables were not replicated in the current samples. Taken together, findings suggest that mindfulness and emotion regulation have unequivocal relations with lower levels of aggression, and should therefore be considered as relevant targets for prevention and treatment programs aimed at reducing aggressive tendencies.
Genetics of diabetic neuropathy: Systematic review, meta‐analysis and trial sequential analysis

Objective

Diabetic neuropathy (DN) is one of the most common complications of diabetes that occurs in more than 67% of individuals with diabetes. Genetic polymorphisms may play an important role in DN development. However, until now, the association between genetic polymorphisms and DN risk has remained unknown. We performed a systematic review, meta‐analysis, and trial sequential analysis (TSA) of the association between all genetic polymorphisms and DN risk.

Methods

Relevant published studies examining the relationship between all genetic polymorphisms and DN were obtained based on a designed search strategy up to 28 February 2019. Odds ratios (ORs) and 95% confidence intervals (CIs) were calculated to assess overall pooled effects of genetic models as well as in subgroup analyses. Sensitive analysis and publication bias were applied to evaluate the reliability of the study. Moreover, TSA was conducted to estimate the robustness of the results.

Results

We conducted a systematic review of a total of 1256 articles, and then 106 publications reporting on 136 polymorphisms of 76 genes were extracted. We performed 107 meta‐analyses on 36 studies involving 12,221 subjects to derive pooled effect estimates for eight polymorphisms. We identified that ACE I>D, MTHFR 1298A/C, GPx‐1 rs1050450, and CAT ‐262C/T were associated with DN, while MTHFR C677T, GSTM1, GSTT1, and IL‐10 ‐1082G/A were not. Sensitivity analysis, funnel plot, and Egger’s test displayed robust results. Furthermore, the results of TSA indicated sufficient sample size in studies of ACE, GPx‐1, GSTM1, and IL‐10 polymorphisms.

Interpretation

Our study assessed the association between ACE I>D, MTHFR C677T, MTHFR 1298A/C, GPx‐1 rs1050450, CAT ‐262C/T, GSTM1, GSTT1, and IL‐10 ‐1082G/A polymorphisms and DN risk. We hope that the data in our research study are used to study DN genetics.

The present study reports the synthesis of poly(2‐isopropenyl‐2‐oxazoline) (PiPOx) dual‐crosslinked hydrogels by both covalent and physical (i.e., metal–ligand coordination) interactions. First, chemical crosslinking of a modified PiPOx polymer containing terpyridine (TPy) unit is achieved by reacting with azelaic acid (non‐anedioic acid). Transient crosslinks are subsequently introduced by complexation of the TPy units with different divalent transition metal ions. This strategy provides access to hydrogels with superior mechanical properties compared to the pure covalently crosslinked PiPOx hydrogels. The mechanical properties and water uptake of the hydrogels could be easily controlled by swelling in different aqueous metal ion solutions. PiPOx hydrogels swollen in Zn2+ solution are found to possess ultrahigh compression strength (9 MPa), remarkable toughness (99 MJ m−3) and outstanding self‐recoverability (98% toughness recovery after swelling for 60 min without external stimuli), which are among the highest reported in literature to date. These remarkable properties are assigned to the thermodynamically stable, but kinetically labile Zn2+‐TPy complexes that produce a dynamic network with fewer imperfections and better adaptive properties under mechanical stress compared to those with other metal ions.

Tellurium (Te), as an elementary material, has attracted intense attention due to its potentially novel properties. However, it is still a great challenge to realize high‐quality 2D Te due to its helical chain structure. Here, ultrathin Te flakes (5 nm) are synthesized via hydrogen‐assisted chemical vapor deposition method. The density functional theory calculations and experiments confirm the growth mechanism, which can be ascribed to the formation of volatile intermediates increasing vapor pressure of the source and promoting the reaction. Impressively, the Te flake‐based transistor shows high on/off ratio ≈104, ultralow off‐state current ≈8 × 10−13 A, as well as a negligible hysteresis due to reducing thermally activated defects at 80 K. Moreover, Te‐flake‐based phototransistor demonstrates giant gate‐dependent photoresponse: when gate voltage varies from −70 to 70 V, Ion/Ioff is increased by ≈40‐fold. The hydrogen‐assisted strategy may provide a new approach for synthesizing other high quality 2D elementary materials.
