An Instrument for Measuring Perception about Social and Human Factors that Influence Software Development Productivity
Authors: Machuca-Villegas Liliana , Gasca-Hurtado Gloria Piedad , Morillo Puente Solbey , Restrepo Tamayo Luz Marcela
Published: March 2021

In terms of productivity in software development, there is specific interest in identifying its influencing factors. For this purpose, several classification approaches have been previously used, which have already recognized technical factors, organizational factors, product factors, project factors, and personal factors. However, these approaches often focus on technical factors over social and human factors (SHFs). Nevertheless, in addition to the obvious technical aspects, the software development process involves problem-solving skills and cognitive aspects and social interaction. In this sense, determining SHFs can lead to software organizations designing strategies for improving team productivity. In this study, we first conducted a preliminary classification of the SHFs identified in the literature. Because this study seeks to assess the factors from the standpoint of software development professionals, we developed and validated an instrument to measure the perception of software development team members about SHFs that may be affecting their productivity. For this purpose, the first four stages of survey-based research were followed: objective definition, survey design, instrument construction, instrument validity, and reliability assessment. The instrument included 79 items assessing 13 different SHFs. After assessing both their validity and reliability, the results demonstrated that the instrument is a valid and reliable tool for measuring SHFs perception among software development team members.

The fatty acids based organofunctional silane protective coatings for concrete
Authors: Szubert K.
Published: March 2021

The possibility of using free fatty acids for the synthesis of new organofunctional silanes is shown. In nature, fatty acids occur in the form of esters with glycerin (fats) and are widely used for production of soap, oil paints, medicines and cosmetics. Of particular interest in this study was the application of organosilicon derivatives of oleic acid for production of coating that would cover the surface of concrete and protect it from water permeation. As a result of proposed silanization, the concrete surface acquired hydrophobic character with the wetting angles up to 115°, and the concrete absorbability was reduced by up to 93%.

Transformations du territoire esthétique : « créer en mapuche » dans l’institution théâtrale chilienne
Authors: Rostollan-Sinet Corentin
Published: March 2021

Nourri par trois ans d’enquête sur les festivals de théâtre chiliens, cet article s’intéresse aux créations de Paula González Seguel et Ricardo Curaqueo Curiche, et au geste politique opéré par ces deux artistes indigènes travaillant « en mapuche » dans l’institution culturelle nationale chilienne. Comment ces créations scéniques depuis l’être-indigène, depuis un être-mapuche aux (re)définitions diverses, offrent-elles de nouvelles options pour la construction d’une communauté politique pluriculturelle future ?Aujourd’hui plus que jamais se fait nécessaire la représentativité indigène dans le processus d’élaboration d’une nouvelle Constitution. À l’heure où s’envisage enfin la possibilité d’un État plurinational, notre article questionne l’opérativité politique d’une récupération des territoires esthétiques, et celle d’une approche de la culture, de ses produits et de ses espaces comme autant de territoires d’interculturalité à réconcilier avec le dissensus et le conflit.
As Grazzi Ellas (primer acto) entre a memória e a explosão do corpo travesti
Authors: Morales Medina Yvets , Campus Melissa
Published: March 2021

O trabalho presenta uma reflexão teórica empírica. É a partir da semiótica da cultura que se aborda a configuração da semiosfera da obra de teatro Grazzi Ellas (monólogo) para colocar na cena teatral as violências que sofrem as pessoas que se autodefinem trans, travestis, transexuais. É uma dramaturgia escrita pela atriz travesti Melissa Campus, com histórias de vida de travestis, e com a sua própria. Para denunciar as violências, e o abandono familiar e social que elas sofrem. Se procura dialogar com as experiências de construção de espaço público, para contextualizar a construção da semiosfera em termos de Iuri Lotman, assim como observar as explosões do signo teatral, e as rupturas que os corpos travestis provocam tanto no cotidiano social, assim no ambiente teatral.
Teatro x la Identidad : itinéraire d’un théâtre militant, du combat des Abuelas de Plaza de Mayo à la croisée des émancipations
Authors: Sanchez Joana
Published: March 2021

Teatro x la Identidad est un mouvement théâtral impulsé en 2000 en Argentine par les Abuelas de Plaza de Mayo, dans le cadre de leur combat pour retrouver leurs petits-enfants nés dans les geôles de la dictature entre 1976 et 1983 et « appropriés » (ou « volés », selon l’expression consacrée) par les militaires. Ces enfants adoptés illégalement et méconnaissant leurs origines ont une vingtaine d’années au tournant des années 2000, si bien que les Abuelas, dans un virage stratégique, décident de s’adresser directement à la jeune génération pour inciter tous ceux qui auraient le moindre doute sur leur ascendance à venir effectuer des tests ADN, seule manière de dévoiler l’appropriation et l’usurpation d’identité. Pour ce faire, elles se tournent vers le milieu théâtral et entreprennent une collaboration appelée à durer puisque le cycle Teatro x la Identidad a lieu chaque année depuis maintenant presque vingt ans. Il marque, en Argentine, le renouveau d’un théâtre de combat, au service d’une cause politique et mémorielle, renouant avec le militantisme qui avait caractérisé certaines dramaturgies des années 1960 et 1970. Or si certaines pièces écrites pour le cycle sont strictement orientées vers la question de l’appropriation d’enfants pendant la dictature militaire, les dramaturges conjuguent parfois cette question à une réflexion plus large sur l’identité et ses enjeux : les appartenances imposées, les identités assignées, les processus d’acculturation et d’assimilation, la complexité de la définition de soi, les différents rapports de domination qui traversent une société et les individus, et participent à la construction identitaire de soi. Une réflexion sur les rapports sociaux de genre, de classe, mais aussi de race, dans un pays où le mythe de « l’Argentine blanche » est encore très prégnant et peut freiner le travail décolonial, se fait ainsi jour sur les planches des cycles Teatro x la Identidad. En ce sens, cet article analyse comment ce théâtre militant, conçu comme un outil au service d’une lutte très particulière, a aussi replacé ce combat singulier à la croisée de luttes pour l’émancipation, dans une démarche intersectionnelle, qui fait de l’identité son pivot articulatoire.

Humo, pero no fuego. Dramaticulas al margen de la ley, al margen del amor…
Authors: Garcés Vergara Claudia Yaneth
Published: March 2021

Claudia Garcés presenta, en el marco de las jornadas de estudio su obra Humo pero no fuego, Dramáticulas Escénicas al margen de la Ley, al margen del Amor. Tres piezas cortas que muestran el mal tristemente banal del conflicto armado colombiano: aquel del Ejército, de los narcotraficantes, de los guerrilleros. Este teatro testimonio refleja en parte la propia experiencia de la teatrista cuyo hermano hizo parte de los civiles inocentes asesinados en el escándalo conocido como aquel de los “falsos positivos”. El grito de la artista se condensa en un formato reducido: primero por la brevedad del drama que se convierte en dramatícula, luego por el espacio escénico. Los actores se mueven en un cuadrado mínimo dibujado en el suelo, y su cuerpo es su único accesorio y decorado. A la vez artista, académica y víctima, Claudia Garcès ofrece una prolongación de su proceso creativo en este texto académico-poético, proponiendo convertir el dolor en un acto de resistencia política.
Un parti de la loi et de l’ordre aux États-Unis ? Essai généalogique et historiographique
Authors: Philippe Yann
Published: March 2021

Comment la sécurité peut-elle être définie aux États-Unis à la fois comme un thème privilégié de la droite et comme une question consensuelle traversant l’échiquier politique ? Afin de répondre à cette question, cet article propose un bilan historiographique permettant de dépasser le paradigme de la polarisation. La mise au jour des sources de l’idéologie sécuritaire contemporaine permet de comprendre comment la politisation de la loi et de l’ordre a contribué à la fois à la résurgence du parti républicain et à la recomposition du paysage politique depuis la Seconde Guerre mondiale.
A Microcosm of Colour and Shine. The Polychromy of Chryselephantine Couches from Ancient Macedonia
Authors: Brecoulaki Hariclia , Sotiropoulou Sophia , Katsifas Christos , Karydas Andreas G. , Kantarelou Vicky
Published: March 2021

The present work examines the polychromy applied to a number of fragmentary ivory small-scale sculptures that served as components of the luxurious decoration of chryselephantine couches from ancient Macedonia. The ivory fragments come from funerary contexts (the tomb of Philip II at Aigai, the Macedonian tomb II of Korinos at Pydna and the Macedonian tomb III of Aghios Athanassios near Thessaloniki), all of which are dated to the last quarter of the fourth century BC. The use of bright pigments on the laboriously executed faces of the figures and their garments, together with the gold leaf applied onto the hair and the background, conveys a powerful effect of polychromy that would have immediately caught the spectator’s eye, enhancing the overall aesthetic and material value of such lavishly decorated furniture. The identification of the pigments and the techniques of their application have been studied with the use of analytical methods (XRF, micro-XRF, XRD and SEM-EDS) and multi spectral imaging (Visible Induced Luminescence).
Vers une restauration scientifique des textiles anciens (xixe-xxe siècles)
Authors: Privat-Savigny Maria-Anne
Published: March 2021

Retracer l’histoire de la restauration des textiles anciens est une entreprise complexe, car les interventions, dont l’objectif a longtemps consisté à prolonger la vie et l’usage de ces étoffes, sont rarement documentées. Les archives certes, mais surtout l’observation des interventions anciennes constituent des sources précieuses d’information qui permettent de dégager trois temps vers une approche scientifique de la restauration des textiles anciens : d’abord la prise de conscience de leur importance historique et la mise en place de procédés, à la fin du xixe siècle, époque où les textiles archéologiques et médiévaux ont passionné les spécialistes, amateurs et collectionneurs ; ensuite, dès les premières années du xxe siècle, l’élaboration d’une méthodologie dont certains principes sont énoncés dans l’enquête menée au cours des années 1930 par l’Office international des musées auprès des principaux responsables de collections de tissus dans le monde ; enfin, dans les années qui suivent la fin de la Seconde Guerre mondiale, les bases de la restauration scientifique de ces œuvres sont posées tandis qu’apparaissent les principaux ateliers de restauration européens.

Comparison of external jugular venous access with internal jugular venous access in pediatric shock
Authors: Kumar Amit , Tandon Krutika , Shah Kushal Mukeshkumar , Tandon Rahul , Patel Mamta R
Published: March 2021

Background:

Central venous access is usually preferred over the peripheral venous route when circulatory failure needs inotropes and vasopressors. However, in resource-limited settings with underskilled personnel, it is not feasible always and so patients are being treated with the peripheral venous route with variable results. We aimed to compare external jugular venous (EJV) access with internal jugular venous (IJV) access for effectiveness, ease of procedure, complications, and treatment cost in pediatric shock.

Subjects and Methods:

This was a prospective, nonrandomized, observational study from January 2014 to June 2015 in 66 pediatric patients with shock at a 7-bedded pediatric intensive care unit. Parents were explained about both routes. Depending on their affordability and consent, one route was chosen. Pertinent data were obtained, and analysis was done as per objectives.

Results:

EJV and IJV had 50 and 16 patients, respectively. Baseline characteristics were comparable. Death and discharge against medical advice rates are high in both the groups. No procedure-related life-threatening complications in any group and local site problems were similar in both the groups. Overall attempts and duration of procedure were similar in both the groups, and although the initial cost of the procedure of the IJV group was higher, overall final hospital bill had no significant difference. The median (Q1, Q3) hours of achieving shock-free status were 48 (24, 96) and 46 (12, 108) (P = 0.412). The median (Q1, Q3) improvement in base deficit at the end of 24 h was −4.5 (−8.1, 0.27) and −1.9 (−4.2, −0.6) (P = 0.259) in the EJV and IJV groups, respectively.

Conclusion:

For pediatric shock management, EJV access is an effective, easy, and cost economic procedure without significant complications as compared to IJV access.

إن سبب جائحة كوفيد-19 المعاصرة هو العامل الممرض الذي يدعى سارس-كوف-2 أو الفيروس التاجي المستجد. تتوقف الظاهرة المرعبة لانتشار هذا الفيروس المسبب للمرض على العديد من المتغيرات الفيزيائية، ولا تخضع للتحليل المقبول بواسطة الطرائق التقليدية. ثمة طريقة بسيطة وسهلة التناول يمكنها أن تحدد (على الأقل وصفيًا) العلاقة بين سرعة انتشار الفيروسات والكميات الفيزيائية التي تؤثر عليها، وهذه هي طريقة تحليل الأبعاد (ح ب). تستكشف هذه الورقة استخدام طريقة حديثة لتحليل الأبعاد في اشتقاق مضروبات لا أبعاد لها تتعلق بمعدل انتشار الفيروسات. يتم إنجاز هذا الاشتقاق باستخدام خوارزمية غاوس-جوردان الشهيرة، والتي تمتلك العديد من المزايا الواضحة للتعامل مع انتفاء الاستقلال الخطي ومع تقسيم المتغيرات إلى متغيرات مدخلات ومخرجات. تستخدم الورقة المضروبات عديمة الأبعاد التي تم الحصول عليها لبناء نموذج رياضي للتنبؤ بسرعة انتشار الفيروس كدالة لمتغيرات الأحوال الجوية والمتغيرات غير البيئية. فشلت المحاولة الأولى لحل المشكلة في العثور على دورما لمتغيري درجة الحرارة والرطوبة، برغم ما هو معلوم لهما من أهمية. العلاج الرصين لهذا الإخفاق هو إدراج متغيرات مؤثرة أكثر ذات تنوع في أبعادها. يتم الحصول على حل عاجل هنا، مع نتائج مرضية للغاية، عن طريق افتراض التكافؤ بين بعدي درجة الحرارة والطاقة، أي عن طريق اعتبار أن ثابت بولتزمان لا أبعاد له.

Sex and Agreement
Authors: Janse Mark
Published: March 2021

This paper is about the relation between natural and grammatical gender in Greek and the ways in which the twain are matched or mismatched. A variety of topics is discussed, including the relation between grammatical gender and declension, the resolution of gender clashes in epicene nouns and the marking of natural gender in common nouns. Particular attention is given to the gendering of neuter diminutives with male or female referents. Age and particular aspects of “maleness” or “femaleness” are shown to be major determinants in triggering male or female instead of neuter agreement patterns, especially on anaphoric pronouns, but occasionally also on other word classes such as predicative adjectives and participles.

Applying chemical control to suppress liverwort (Marсhantia polymorpha L.) and other mosses when growing containerized seedlings of pine and spruce
Authors: Egorov Alexander , Bubnov Aleksandr , Pavluchenkova Lidiya , Partolina Anna , Postnikov Anton
Published: March 2021

The spread of bryophytes (liverworts and green mosses) on the substrate surface in containers and cassettes poses a significant problem when growing containerized coniferous seedlings. It requires a complex control programme to significantly minimize the negative effect which mosses, in particular Marсhantia polymorpha L., pose to the growth of containerized pine and spruce seedlings. In addition to the preventive and agrotechnical measures, this programme should also involve application of the physiologically active substances. North American and European nurseries have faced this problem for a long time, Russian nurseries have started to experience it only in recent years due to increased output of containerized pine and spruce seedlings grown in greenhouses. In this paper, we assessed the effectiveness of some herbicides for moss control and their selectivity to pine and spruce seedlings of different ages. The following chemicals were applied in the tests: Goal 24% EC (a.i. oxyfluorfen), Stomp 33% EC (a.i. pendimethalin), Velpar 90% SP (a.i. hexazinone), Pledge 25% WP (a.i. flumioxazin), Mogeton 25% WP (a.i. quinoclamine), Granstar 75% WDG (a.i. tribenuron-methyl), Anchor-85 75% WDG (a.i. sulfometuron methyl) as well as cinnamon oil and baking soda. The experiments were conducted in greenhouses and outdoor fields. It was found that the pre-emergent (before the pine and spruce shoots appear) application of Mogeton WP and baking soda in the greenhouse resulted in the effective suppression of green mosses for up to 20 weeks after the treatment, without any signs of injury in seedlings. Under the same conditions, Goal EC, Stomp EC, Pledge WP and their mixtures in different combinations, as well as Velpar SP caused significant damage to pine and spruce seedlings. The post-emergent treatment by Velpar SP, Pledge WP, Mogeton WP, Granstar WDG, Anchor-85 WDG, as well as cinnamon oil and baking soda, provided effective and long-term control of liverwort and green mosses in cassettes without damage to the seedlings. Key words: Marchantia polymorpha L., pine, spruce, efficacy, selectivity
Planície do rio Jacareí após os movimentos de massa de 2011: considerações a partir da análise granulométrica de trincheira e mudanças do canal
Authors: Paz Otacílio Lopes de Souza da , Paula Eduardo Vedor de
Published: March 2021

A planície costeira paranaense foi formada por distintos processos continentais e marinhos. Entre eles, citam-se os movimentos de massa. Um exemplo extremo desse processo foi observado em março de 2011 na serra do mar paranaense, onde uma sequência de deslizamentos, fluxos de lama e detritos e inundações com alta carga sedimentar atingiram a bacia do rio Jacareí (porção central do litoral do Paraná). Objetiva-se analisar a granulometria da deposição sedimentar deixada pelo evento a partir de uma trincheira aberta nas margens do rio Jacareí, bem como investigar as mudanças ocorridas no canal em sua porção de planície, tendo como base os anos de 2011, 2012 e 2019. A análise granulometria foi feita por meio de técnica de pipetagem e peneiramento mecânico, enquanto a análise do canal foi realizada em ambiente de sistema de informações geográficas, com base em imagens orbitais e imagens coletadas por aeronave remotamente pilotada. O rio foi totalmente assoreado nos trechos mais a montante e médio da planície em 2011, sendo o canal reaberto posteriormente. Em 2019, o rio Jacareí apresentou em um trecho um retorno ao padrão sinuoso. A camada deposicional deixada pelo evento apresentou 50 cm de espessura e é composta predominantemente de material mais grosso (areia muito grossa, grânulos e seixos). Foram identificados ambientes de deposição nas camadas sedimentares abaixo da camada deixada pelo evento. Recomendações de análises em maior detalhe do canal do rio e dos depósitos gerados ao longo de toda a planície são apresentadas.

Published: March 2021

This study focuses on the design of a campus public space, located within the Faculty of Engineering, Chiang Mai University, Thailand. This area faces extreme temperatures, creating uncomfortable outdoor thermal conditions and hindering activities that are expected to support the learning and social cohesion needs of students. To create the best conditions in this space, three design alternatives such as adding a pond, large trees, or shrubs were considered, and the Physiologically Equivalent Temperature (PET) was used to calculate the outdoor thermal comfort index for each alternative. The alternatives were then compared to the base case. The PET can be calculated using the ENVI-met simulation software following the appropriate field data collection and calibration process. The results showed that adding large trees in the south-west area is the best design alternative. The PET for this alternative was 3.17 % lower than the base case. In addition, this design workflow is an effective working model for further outdoor public space designs to meet the constraints of effective sustainable development in any tropical campus area.
Innovative Strategy to Meet the Challenges of the Future Digital Society
Authors: Bonnaud Olivier
Published: March 2021

Today, we are experiencing a societal revolution with the development of digital technologies, and it brings new challenges. Indeed, the number of connected objects, intelligent sensors and IoTs are increasing exponentially. The same goes for the resulting energy consumption. Beyond 2030, without a radical transformation of communication technologies and protocols, the digital world will be at an energy dead end. All these objects are physically realized with microelectronic devices and systems. This analysis of the microelectronics community has led the French government to recognize an electronics sector that is becoming a priority area of industrial policy. The Strategic Committee of this sector has proposed innovations applied to the entire digital chain including all facets of the microelectronics field and human skills and know-how.

Influence of Cold Sensation on Plantar Tactile Sensation for Young Females
Authors: Wang Tianyi , Okada Shima , Makikawa Masaaki , Endo Masayuki , Ohno Yuko
Published: March 2021

Cold sensation (CS) is a cold feeling on people’s hands or feet; this is a well-known health problem for young females. Plantar tactile sensation plays an important role in postural control and is affected by skin temperature. However, there is no research focusing on the relation between CS and plantar tactile sensation. In this study, we address the question of whether the CS influences plantar tactile sensation. 32 non cold sensation (Non-CS) and 31 cold sensation (CS) young females have participated in this research. A tactile sensation test was conducted at five plantar points (first and fifth toes, first and fifth metatarsal heads, and heel). Experimental results showed that although there was no significant difference at the first and fifth toes as well as the first metatarsal head and heel, the sensation threshold at the fifth metatarsal head for CS was lower than the Non-CS (21.61 ± 8.10 μm, 27.42 ± 11.02 μm respectively, p < 0.05).  It was concluded that plantar tactile sensation for young females with cold sensation was more sensitive compared to healthy subjects.
Community-based Learning and Social Movements
Authors: Mayo Marjorie
Published: March 2021

The rise of Far Right populism poses major challenges for communities, exacerbating divisions, hate speech and hate crime. This book shows how communities and social justice movements can effectively tackle these issues, working together to mitigate their underlying causes and more immediate manifestations. Showing that community-based learning is integral to the development of strategies to promote more hopeful rather than more hateful futures, Mayo demonstrates how, through popular education and participatory action research, communities can develop their own understandings of their problems. Using case studies that illustrate education approaches in practice, she shows how communities can engineer democratic forms of social change.

From negotiating a sense of legitimacy when 'not feeling trans enough' to how identities can shift over time, it reveals important nuances of diverse gender identities while offering crucial insights into trans-related healthcare inequalities. The findings of this ground-breaking research mark an important contribution to the wider fields of gender studies, LGBTQ scholarship and medical policy.
Maternal Imprisonment and Family Life
Authors: Booth Natalie
Published: March 2021

Exploring the untold experiences of family members and friends caring for the children of female prisoners in England and Wales, this book sheds light on the collateral damage that incarceration causes those who take over caregiving responsibilities for the children of female prisoners. Providing new qualitative research on the lived experiences of caregiving relatives, alongside theoretically informed and policy-relevant insights, Booth shows the difficult and damaging consequences of the 'family sentence' they serve. Exploring the stigma, scarce statutory support and policy neglect they face, she offers much-needed evidence to encourage the development of a more inclusive, understanding and family-oriented justice system.

Including a range of perspectives, this book highlights the systemic changes needed for social workers and other key professionals to ensure that children and parents participate more meaningfully in decision-making, which will improve the long term outcomes for children and their families.
Investigating Corruption in the Afghan Police Force
Authors: Singh Danny
Published: March 2021

Based on unprecedented empirical research conducted with lower levels of the Afghan police, this unique study assesses how institutional legacy and external intervention have shaped the structural conditions of corruption in the police force and the state. Taking a social constructivist approach, the book combines an in-depth analysis of internal political, cultural and economic drivers with references to several regime changes affecting policing and security, from the Soviet occupation and Mujahidin militias to Taliban religious police. Crossing disciplinary boundaries, Singh offers an invaluable contribution to the literature and to anti-corruption policy in developing and conflict-affected societies.
Sharing Milk
Authors: Carter Shannon K. , Reyes-Foster Beatriz M.
Published: March 2021

The feeding of human milk to socially and biologically unrelated infants is not a new phenomenon, but the Euroamerican values of individualism have generated expectations that mothers are individually responsible for feeding their own infants. Using a bio-communities of practice framework, this dynamic new analysis explores the emotional and material dimensions of the growing milk sharing practice in the Global North and its implications for contemporary understandings of infant feeding in the US. Ranging widely across themes of motherhood, gender and sociology, this is a compelling empirical account of infant feeding that stimulates new thinking about a contentious practice.
Getting In and Getting On in the Youth Labour Market
Authors: Leonard Pauline , Wilde Rachel
Published: March 2021

Based on up to date qualitative and ethnographic research, this book examines youth education-to-work transitions in the UK. Using the theoretical lens of a Foucauldian governmentality approach, the authors consider the 'why' and 'how' of youth employability training and demonstrate how different employability schemes planned and operationalised in diverse geographical and economic landscapes work in practice. The book examines and compares a range of employment entry route programmes and reveals the tension between employability and good quality employment, and the ways in which young people from varying social and regional backgrounds are positioned very differently within this.

Why Minor Powers Risk Wars with Major Powers
Authors: Bobić Marinko
Published: March 2021

Through a range of case studies spanning the post-Cold War period in Iraq, Moldova and Serbia, this innovative book breaks new ground in its study of asymmetric conflicts where warring sides exhibit vast power differentials. It uses multiple theories to examine the different pathways that encourage minor powers to engage in both offensive and defensive wars that they are likely to lose, analysing domestic crisis as a key catalyst and considering ways to mitigate conditions that drive conflict. The author provides an important framework that can be applied to contemporary conflicts elsewhere.
Sharing Care
Authors: Brooks Rachel , Hodkinson Paul
Published: March 2021

Drawing on detailed qualitative research, this timely study explores the experiences of fathers who take on equal or primary care responsibilities for young children. The authors examine what prompts these arrangements, how fathers adjust to their caregiving roles over time, and what challenges they face along the way. The book asks what would encourage more fathers to become primary or equal caregivers, and how we can make things easier for those who do. Offering new academic insight and practical recommendations, this will be key reading for those interested in parenting, families and gender, including researchers, policymakers, practitioners and students.
Bourdieu and Affect
Authors: Threadgold Steven
Published: March 2021

Steven Threadgold's study represents the first comprehensive engagement of Pierre Bourdieu's influential sociology with affect theory. With empirical research and examples from sociology, it develops a theory of 'Affective Affinities,' deepening our understanding of how everyday moments contribute to the construction and remaking of social class and aspects of inequalities. It identifies new ways to consider the strengths and weaknesses of Bourdieusian principles and their interaction with new developments in social theory. This is a stimulating read for students, researchers and academics across studies in youth, education, labour markets, pop culture, media, consumption and taste.

Authors: Rudychev V.G. , Lazurik V.T. , Rudychev D.V. , Rudychev Y.V.
Published: March 2021

The possibility of decreasing the depth-dose inhomogeneity in polyethylene with double-sided and one-sided electron irradiation at diﬀerent angles with a maximum eﬃciency of beam use is investigated. The least squares method was used to determine the optimal parameters, the thickness of the object, and the fraction of the beam incident on the object at angles Θ = 0◦ and Θ ≠ 0◦. When irradiating with a main beam with an angle Θ = 0◦ and an additional one with Θ = 70◦, it was shown that at an eﬃciency of ≈ 97%, the technique allows reducing the deposited dose inhomogeneity in objects from 70, 51 and 38% to ∼17%, and with ﬁlters from Al (eﬃciency ≈94%) to 5% for electron energies of 2,5, and 9MeV respectively.
