Authors: Lightfoot Elizabeth , Nienow Mary , Moua Kao Nou L. , Colburn Gregg , Petri Alissa
Published: August 2021

This article describes a qualitative study designed to explore both how community practice social workers identify professionally and to examine their view towards professional regulation. Thirty-five MSW-level social workers in a large metropolitan region who self-identified as community practice social worker participated in in-depth interviews. The respondents shared their views regarding professional identification as social workers and the impact of professional identity on their work as community practitioners. Approximately half of the respondents indicated that they only sometimes or never identify as a social worker. The respondents were generally critical of the licensing burden placed upon them as community practice social workers.
Bringing agency back in: the missing link between identity, knowledge, and mediated discourse
Authors: Tschötschel Robin Sebastian , Jacovs Thomas
Published: August 2021

In an era often characterised by the notions of “post-truth” and “identity politics”, the nexus between communication, knowledge, and identity forms a crucial realm for social-scientific analysis. However, existing approaches, inspired by content, frame, and discourse analysis often rest on a limited conceptualisation of the agency exercised by those appearing in mediated discourse as speakers or subjects. To remedy this, we argue for an intervention inspired by Actor-Network Theory (ANT) and propose a framework combining ANT and poststructuralist Discourse Theory (PDT). Building on a discussion of the theoretical similarities between the two, our core proposal is to study the associations between identity markers and knowledge claims at the sentence level to make transparent how and by whom they are articulated. The nuance gained deepens our understanding of the discursive construction of identity and knowledge, shedding light on the links between identity polarisation and the politicisation of facts.
Polarisation vs consensus-building: How US and German news media portray climate change as a feature of political identities
Authors: Tschötschel Robin Sebastian
Published: August 2021

Perceptions of climate politics often align with individual political leaning and associated media consumption patterns, pointing to a need for a fine-grained understanding of how the media integrate climate change with political identities. This study presents an in-depth qualitative analysis of political identity portrayals from 229 articles published in six German and US news outlets during May-July 2019. The results show that the outlets consumed by left- and right-leaning audiences emphasise oppositional identity portrayals, portraying features that are likely to trigger a negative response towards political identities typically op-posed by their recipients. The outlets with a more balanced or centrist audience offer a wider array of identity portrayals and emphasise policy questions over fundamental beliefs. Observed patterns differ considerably between Germany and the US, reflecting political and media system differences. The results add to understanding how the media contribute to political polarisation and consensus-building regarding climate change.
The Roots of Racialized Travel Behavior
Authors: Barajas Jesus
Published: August 2021

Transportation inequities, particularly in the United States, result in part from historical and contemporary racism in planning, policy, urban development, decision making, and societal institutions. They have limited the mobility and access to opportunity for Black, Indigenous, and people of color, and shaped the ways that they travel. This chapter reviews the literature on racial and ethnic identity in travel behavior, examining the history and claims of transportation injustice. The chapter explores the barriers that historically marginalized communities experience as a result of disproportionate policing, safety and security issues, and neighborhood othering and belonging—that is, inviting suspicion because a person appears to be “out of place” in a neighborhood. It concludes by making the case for why transportation planners must consider race and racism explanatory factors in travel and why race-neutral planning processes exacerbate disparities.
Insults, criminalization, and calls for violence: Forms of hate speech and offensive language in German user comments on immigration
Authors: Paasch-Colberg Sünje , Trebbe Joachim , Strippel Christian , Emmer Martin
Published: August 2021

In the past decade, the public discourse on immigration in Germany has been strongly affected by right-wing populist, racist, and Islamophobic positions. This becomes evident especially in the comment sections of news websites and social media platforms, where user discussions often escalate and trigger hate comments against refugees and immigrants and also against journalists, politicians, and other groups. In view of the threatening consequences such sentiments can have for groups who are targeted by right-wing extremist violence, we take a closer look into such user discussions to gain detailed insights into the various forms of hate speech and offensive language against these groups. Using a modularized framework that goes beyond the common “hate/no-hate” dichotomy in the field, we conducted a structured text annotation of 5,031 user comments posted on German news websites and social media in March 2019. Most of the hate speech we found was directed against refugees and immigrants, while other groups were mostly exposed to various forms of offensive language. In comments containing hate speech, refugees and Muslims were frequently stereotyped as criminals, whereas extreme forms of hate speech, such as calls for violence, were rare in our data. These findings are discussed with a focus on their potential consequences for public discourse on immigration in Germany.

The Immunologic Properties of Undifferentiated Stem Cells from Human Exfoliated Deciduous Teeth (SHED) and Its Potential Application in Bone Regeneration
Authors: Abdullah Dr. Nurul Asma
Published: August 2021

Introduction: Stem cells from human exfoliated deciduous teeth (SHED) are highly proliferative, clonogenic cells capable of differentiating into osteoblasts and inducing bone formation. It is a potential alternative for stem cell bone regeneration therapy. However, stem cell therapy carries the risk of immune rejection mediated by inflammatory cytokines of the human defense system. Objective: This preliminary research studies the interaction between SHED and the immune system by determining the inflammatory cytokines profile and osteogenic potential of SHED. Methods: Human fetal osteoblasts (hFOb) cell line and isolated SHED were cultured and total RNA was extracted, followed by reverse transcription cDNA synthesis. Semi-quantitative reverse transcription PCR and Multiplex PCR were performed to detect the expression levels of OPG/RANKL and TNF-α, IL-1β, IL-6, IL-8 and TGF-β in both cell types. Results: Analysis showed that SHED expressed significantly lower amounts of IL-1β, IL-6, and IL-8 compared to hFOB. IL-1β is a potent bone-resorbing factor, while IL-6 and IL-8 induce osteoclastogenesis and osteolysis respectively. SHED did not express TNF-α which stimulates osteoclastic activity. SHED demonstrated high OPG/RANKL ratio, in contrast with that of marrow stem cells described in previous studies. Our findings suggest that SHED may have improved immunomodulatory profile in terms of promoting relatively lower inflammatory reaction during transplant and enhancing bone regeneration. Conclusion: SHED has a potential to be a good source of osteoblasts for bone regeneration therapy. Further studies on the immunomodulatory properties of SHED-derived osteoblasts are necessary to enable stem cell therapy in immunocompetent hosts

Authors: Rafraf Maryam
Published: August 2021

Introduction: Obesity is a growing public health problem in both developed and developing societies. The aim of this cross-sectional study was to estimate the prevalence of overall obesity determined by body mass index (BMI) and abdominal obesity identified by waist circumference(WC) percentiles, waist to hip ratio(WHR) and waist to height ratio (WHtR), in adolescent girls attending high school in Tabriz, Iran. Methods: A sample of 985 girls was selected by stepwise random sampling from five districts of Tabriz. Weight, height, WC and hip circumferences ( HiC) of the subjects were measured and BMI, WHR and WHtR were calculated. Overweight and obesity were defined according to International BMI Cut-Off Points for adolescents. WC >90th percentile, WHR>0.80 and WHtR≥0.50 were categorized as abdominal obesity. Results: The prevalence rates of obesity and overweight were 2.8% and 16.4%, respectively. Abdominal obesity defined by WC percentiles, WHR, and WHtR were seen in 3.2%, 4.0%, and 18.2% of subjects, respectively. WHtR determined the highest prevalence of abdominal obesity in subjects compared to WC and WHR. WC, WHR, and WHtR were significantly related to BMI. Conclusions: Overall obesity and abdominal obesity are substantially prevalent in the studied adolescent girls. Further studies are needed to identify risk factors for the obesity in our studied population. Findings emphasize the importance of establishing community–based interventions in order to prevent the development of adolescent obesity and its complications in adulthood.

Published: August 2021

Introduction: Epidemiology of fungal infections in an infectious disease reference centre is different from other institutions. This study aimed to look at the scenario of fungal infections at an infectious disease reference centre in Malaysia. Methods: All positive fungal cultures from an infectious disease reference centre were identified by routine mycology laboratory methods. Patient demographic, laboratory and clinical data were collected and analyzed. Duplicate data were excluded. Results: Middle-aged Malay males were the most common group. However, increased proportions of Chinese, Myanmar and Indonesians reduced the Malay predominance in HIV-positive group. In all patients, Candida species represented 64.1% isolates, followed by Cryptococcus neoformans (14.7%) and Penicillium marneffei (14.7%). Among HIV[1]positive individuals, C. neoformans (37.9%) was the most common species, followed by P. marneffei (35.6%) and all Candida species (17.2%). In contrast to other non-infectious disease reference centres, common causes of fungaemia included P. marneffei (43.5%), Candida species (25.8%), C. neoformans (24.2%) and H. capsulatum (6.5%). Conclusion: The prevalence of fungal infection at an infectious disease reference centre is different from other non-infectious disease reference centres. This may have an impact on current antifungal practice especially empiric antifungal therapy, patient morbidity and mortality.
Late Leaf Spot Defoliation, Microclimate Modification, and Southern Stem Rot Development in Peanut (Arachis hypogaea L.) in South Carolina
Authors: Munir M. , Kirk K. R. , Plumblee M. T. , Anco D. J.
Published: August 2021

Southern stem rot (SSR) of peanut, caused by Athelia rolfsii, is commonly influenced by environmental conditions. Defoliation from late leaf spot (LLS), caused by Nothopassalora personata, alters canopy structure and has the potential to affect microclimates. A better understanding of the potential interaction between SSR and LLS through potential microclimate modification might contribute to improved disease management. Eight field experiments were conducted from 2016 to 2019 to investigate the effect of LLS defoliation on peanut canopy and soil microclimates and SSR development. To encourage different levels of LLS defoliation, 3 spray programs (3, 4 and 6 chlorothalonil applications) were applied across four cultivars varying in susceptibility to LLS and SSR via a split-plot design. Defoliation was rated every 2 weeks from 75 days after planting (DAP) to harvest. Canopy and soil temperature and soil moisture were recorded from 75 to 140 DAP. Interaction of LLS spray program and peanut cultivar significantly affected LLS defoliation in nearly all trial years except in 2019 where low disease pressure occurred due to dry weather. Significant relationships were observed between LLS defoliation and daily maximum canopy temperatures and between area under LLS defoliation curve (AUDC) and slope of daily canopy temperature change. The influence of LLS defoliation on the microclimate was generally erratic. The relationship between AUDC and SSR was not significant. Results from this study suggest that the influence of LLS on microclimate was insufficient to substantially affect SSR development.

Purpose: to assess the drainage runoff potential in Russia for humidification purposes using drainage-watering systems. Materials and methods. The informational basis of the research was made up of information received from federal state budgetary institutions on land reclamation and agricultural water supply, in the context of the diverted drainage runoff volume from drainage, drainage-watering and drainage-irrigation systems of double soil water regime control as well as data from annual monitoring. The following software products Microsoft Excel, ArcGIS, MathCAD were used to process the data on drainage runoff indicators. General scientific methods were used to analyze the data obtained on drainage runoff volume and graphic material. Results. When quantifying the drainage runoff volume and its mineralization, complications associated with a shortage, and in some cases with a lack of data on drainage runoff from reclamation systems arose. Based on the data received, 22 regions with operating drainage reclamation systems were identified. For each reclamation system, the drainage runoff volume and the total area of drained lands were determined. The regions with the largest, sufficient and insignificant volumes runoff have been identified. For some regions, data on the salinity of the drainage runoff were obtained and analyzed. Conclusions. As a result of analysis it was revealed that almost 50 % of the territories served by drainage systems can be moistened with drainage runoff in full volume of all serviced areas with accumulation in regulating tanks; in the rest of the regions additional water withdrawal from the water source is required. Indicators of drainage runoff salinity are 0.22–1.60 g/l, in some systems they reach 2.1–4.7 g/l, which indicates the possibility of using agricultural crops in irrigation on various types of soils and for fish farming.

Purpose: improvement of the irrigated agriculture system and justification of the rational cropping pattern, taking into account the possible provision of biological productivity of agricultural land for the period up to 2030. Materials and methods: the optimal values of the cropping patterns used in the structure of reclamation complex were used as key criteria for improving the system of irrigated agriculture. The demand and potential level of export of agricultural products and options for their processing were taken into account. The proposed cropping patterns on irrigated lands were obtained based on the results of ranking indicators: cereals (wheat, corn), industrial (soybeans, etc.), vegetables (including potatoes), beets (table and fodder). Results: the main conditions for carrying out reclamation measures aimed at increasing feed production, increasing the energy content and protein nutritional value of feed, contributing to the increase of farm animals productivity, were revealed. With a predicted high level of yield by 2030, its growth may be: for fodder – 2.5 times, sugar beet – 2.4 times, flax – 3.0, sunflower – 2.6, potatoes – 1.9, rice – 1.7 times. Conclusions. The main requirements for cropping pattern optimization have been determined: ranking according to the degree of global demand for agricultural products, which determines the trends of its production in the Russian Federation; optimization of the production structure of certain groups of crops in the domestic market, as well as for export to the foreign market; application of scientifically based crop rotation systems; work on the selection of varieties and hybrids of crops; improvement of irrigation equipment and technologies. Optimization of cropping patterns, including fodder crops in irrigated crop rotations, and restoration of soil fertility can also increase the output of livestock products – to ensure the country's food security.

Purpose: to identify the optimal combination of the seeding rate of seeds and the background of fertilizers to achieve a high yield of a new peas Premier variety, as well as to study the peculiarities of water consumption of the crop under the soil and climatic conditions of Azov zone Rostov region. Materials and methods. The studies were carried out in Aksai district Rostov region in 2019–2020. The soil of the experimental site is represented by ordinary calcareous medium-thick light loamy chernozem on loess-like loam. The experiments used the Premier pea variety. Factor A: seeding rates (0.8 (control); 1.0; 1.2 million pcs/ha); factor B: fertilizer backgrounds (high – N30Р80K80; medium – N15Р40K40; control without fertilizers) were studied. During the field experiment, the generally accepted methods were used (B. A. Dospekhov, 1985; A. N. Kostyakov, 1961; A. F. Vadyunina, 1986). Results. When growing peas in rainfed conditions, the priority effect on grain yield is provided by the moisture supply of plants during the critical period of water consumption. In years with optimal (GTC = 1.37) and stressful (GTC = 0.22) conditions of this growing season, the difference in yield indicators reached 47.0–51.9 %. The change in the seeding density from 0.8 to 1.0 and 1.2 million pcs/ha contributed to an increase in the average grain yield under different nutritional backgrounds, respectively, by 21.3–25.0 and 34.0–40.5 % compared to control. The fertilizer rate N15Р40K40 increased the peas yield at different sowing densities by 16.0–21.2 %, and a high background (N30Р80K80) – by 38.6–42.2 % compared to natural fertility conditions. The best payback of fertilizers by an increase in yield was obtained in the variant with a high background of nutrition N30P80K80 and a seeding rate of 1.2 million units/ha – 3.32 kg/kg. Conclusions. The best average grain yield was ensured at the rates of fertilization N30P80K80 and seeding of seeds of 1.2 million units/ha, reaching 2.26 t/ha.

Purpose: development of an outlet and fishing structures works, providing for fish release from fish-breeding reservoirs, their seining, transfer and inlet into feeding reservoirs using non-contact technology. Materials and methods. The basis of the research was the data of studying the applied technologies, structures and means of intra-complex fish transfer between fish-breeding facilities and during stocking of reservoirs. Results. When fish are cultivated in fish breeding complexes, it is necessary to transfer them from nursery reservoirs to wild or stocked objects for fish farming and their biological reclamation. When providing fish-breeding activities, fish are released from nursery reservoirs by means of water outlets, seined in fish-traps, transfered and released into a water body. The applied complexes of structures provide for a physical effect on fish, which leads to injury to a part of the fish planting material. To exclude this, design solutions for fish outlet and fish processing facilities and live fish containers operating in the complex, providing the release, seining, transfer and inlet of fish using non-contact technology with technical means are proposed. Conclusions. A layout and design solution for a unit of linearly spaced interconnected fish-breeding structures, including a bottom fish outlet and a container fish trap, providing, when they work together, release and seining fish fry cultivated in fish-breeding reservoirs, is proposed. The applied and proposed technological schemes of functioning of the complex of structures, devices and means for fish release from fish-breeding basins, their catching, transfer and admission to the feeding reservoir are presented. A constructive solution for a live fish container for non-contact fishing, movement and admission of fish stocking material into the reservoir to be stocked is proposed.

Purpose: to substantiate the main provisions of landscape agroforestry reclamation. Methods: landscape-chorionic, ecotonic and catenary-basin approaches. Results. A provision on the forest agrarian chorion formed by the core – the phytomass accumulation of the forestry stows and the reclamation fields of its impact on the agricultural landscape has been developed. The characteristics of these fields depend on the intensity of the material-energy manifestations of the chorionic core, which changes in connection with the agro-environment dynamics and the forest-agrarian chorion development. This leads to the emergence of local forest-agricultural landscapes and their ecotones. Forestry stows mesoecotones of and regional forests macroecotones organize the landscape space. In this case, the slope landscapes combine landscape-geochemical flows, and the catchment areas of gullies and watercourse basins combine the systems of such flows. Forest agrarian chorions, due to their influence fields and filtration-barrier function of ecotones, influence the direction and properties of landscape-geochemical flows, changing the ratio of the articles of the water balance of the territory, material-energy removal and accumulation of matter and energy, concentration and dispersion of information, productivity and product quality of agricultural landscapes. Primary catchments of gullies with a well-developed network of valleys, hollows and gullies are characterized by landscape-geochemical microarens, and the basins of watercourses of various orders are mega- and macroarens, which, respectively, represent local forest-agricultural landscapes, districts, regions, and zones of landscape agroforestry reclamation. All forest agrarian chorions (forest strips, groves, etc.) are grouped according to the main criteria: protection of fields and gardens, protection of meadows and pastures, organization of landscape space. Conclusions. The terminology and meanings of agroforestry reclamation and landscape science have been agreed upon. The main provisions of landscape agroforestry have been substantiated: forest agrarian chorion, forest edge ecotone, basin structure and qualitatively homogeneous groups of multifunctional forest agrarian chorions.

Недавно обнаруженные люминесцентные свойства неароматических аминокислот с зависимой от возбуждения фотолюминесценцией в отсутствие конъюгации внутри отдельных молекул вызвали большой интерес. Хотя существование явления внутренней люминесценции больше не вызывает сомнений, механизм, участвующий в этом процессе, остается неясным. В работе на примере изучения спектрально-люминесцентных свойств L-лизина и L-аргинина авторы попытались продвинуться в понимании этих процессов с помощью адсорбционной спектроскопии в ультрафиолетовом и видимом диапазонах, а также спектроскопии стационарной и синхронной флуоресцентной спектроскопии.

Фактор транскрипции UxuR является репрессором ряда генов катаболизма гексуронатов. Он может образовывать гетеродимеры со своим паралогом ExuR, что в присутствии глюкуроната ведет к активации репрессируемых UxuR генов. Ранее методом гибкого последовательного молекулярного докинга было предсказано, что сахара связываются с междоменными линкерами UxuR и ExuR, влияя на взаимное расположение доменов белков. Аналогичные расчеты на моделях гетеродимера UxuR-ExuR, соответствующих четырем точкам его молекулярно-динамической симуляции, тоже предсказывают связывание сахаров с междоменными линкерами. Изменения в конформации белка модулируют место и степень аффинности такого взаимодействия. Выдвигается гипотеза о появлении более стабильных комплексов UxuR-ExuR-глюкуронат с повышенной аффинностью связывания с некоторыми конформациями междоменных линкеров белков. Это уменьшает число свободных мономеров, а значит, и гомодимеров UxuR в присутствии этих сахаров, и снижает репрессию UxuR его регулона.

Обзор посвящен методам исследований сверхслабых свечений биологических объектов, причем кроме современных методов, направленных на исследования в видимом, ближнем инфракрасном и ближнем ультрафиолетовом диапазонах, значительное внимание уделено анализу методологии исследований компоненты, относящейся к среднему ультрафиолетовому диапазону (в ранних работах называемой митогенетическим излучением). Исследования митогенетического излучения проводились в 1923-1948 гг. и остаются частично спорными. Многие полученные результаты, революционные для того времени, уже подтверждены, а научная проблематика остальных представляет значительный интерес (например, фундаментальные результаты, касающиеся деления клеток и канцерогенеза, ранняя онкодиагностика), поэтому анализ их методологии актуален для дальнейшей экспериментальной проверки этих исследований. В первой из трех частей обзора рассмотрены общие вопросы - история исследований и развития методов, классификация и свойства сверхслабых свечений, прикладное и фундаментальное значение исследований (вторая и третья части обзора посвящены соответственно биологическим и физическим методам исследований).

Представлены результаты мониторинговых наблюдений трех участков р. Москва, различающихся по уровню загрязнения с применением комплекса параметров флуоресценции хлорофилла. Фотосинтетическая активность фитопланктона по всему руслу была неодинаковой. Наиболее высокие значения активности фотохимических процессов фитопланктона обнаружены на условно чистом участке реки (на входе в город), тогда как на загрязненных участках (середина реки и на выходе из города) активность фитопланктона была снижена. Эффективность световых реакций фотосинтеза в фотосистеме II (FV/FM, PIABS) у фитопланктона весной была выше, чем в летний период. Эти процессы сопровождались уменьшением диссипации поглощенной энергии в тепло (φDo). Инкубация фитопланктона из р. Москва в присутствии солей хлорида ртути выявила различия в чувствительности к токсическому воздействию фитопланктона из разных частей реки, а также более низкую устойчивость фитопланктона к ртути в летний сезон по сравнению с весенним. Наиболее чувствительным параметром к токсическому воздействию ртути был индекс производительности фотосистемы II (PIABS), который можно рекомендовать при проведении биотестирования и биомониторинга активности фотосинтетических реакций фитопланктона в природных условиях.

Проведена оценка влияния различных уровней давления газовой смеси монооксида углерода и кислорода на сохранность ткани сердца крысы при пролонгированной гипотермической (4°С) газовой консервации с продолжительностью хранения образцов в течение 24, 36 и 48 ч. При 24-часовой консервации снижение давления газовой смеси СО/О2 (в соотношении 1:1) с 6.5 до 1.5 атм привело к появлению инфарктных зон (17.74 ± 3.5% от всей площади образца) и нарушению сократительной функции желудочков. При этом показатели сохранности сердца после хранения под давлением 3.5 и 6.5 атм достоверно не различались. При 36- и 48-часовой консервации выявлено преимущество давления величиной 6.5 атм по сравнению с давлением 3.5 атм. Уровни инфарктной зоны после 48 ч консервации составили 33.65 ± 11.96% и 61.92 ± 6.38% соответственно. Поисковое введение в газовую смесь аргона (СО:О2:Ar = 2:2:1) для синергического увеличения уровня органопротекции в экспериментах по консервации сердца под давлением 3.5 атм не выявило значимого улучшения показателя сохранности сердечной ткани. Рассмотрены потенциальные механизмы защитного действия смеси монооксида углерода и кислорода в условиях гипотермической консервации.

Показано влияние гибернации на количество индивидуальных фосфолипидов и нейтральных липидов, а также состояний оцепенения (спящие суслики) и выхода из него (зимние активные суслики) на синтез липидов в ткани неокортекса. Обнаружено снижение количества жирных кислот и диглицеридов в неокортексе активных сусликов по сравнению с летними. Включение метки в ткань и липиды неокортекса у пробудившихся сусликов было уменьшено на 25%, что объясняется снижением концентрации 14С-ацетата за счет использования ацетата в процессе дыхания у пробудившихся сусликов. Липиды неокортекса суслика Spermophilus undulatus принимают участие в адаптации к гипобиозу путем роста количества общей фракции фосфолипидов и модификации фосфолипидного состава с увеличением долей фосфатидилхолина, фосфатидилинозитола и фосфатидилсерина.

Проведено сравнительное изучение противоопухолевой и цитотоксической активности двух полимерных соединений на основе полиакриловой кислоты, содержащих золото (аурумакрил) и серебро (аргакрил). Препараты эффективно ингибируют развитие солидных опухолей мышей (карцинома легких Льюис, аденокарцинома Акатол, аденокарцинома Са-755) и обладают выраженным цитотоксическим эффектом в отношении клеток опухоли человека (культура клеток MCF-7). Коэффициент торможения роста опухолей мышей колеблется в пределах от 55 до 90% по сравнению с контролем. Показатель цитотоксического эффекта ИК50 составляет 25 мкг/мл и 100 мкг/мл для аргакрила и аурумакрила соответственно. Чувствительность к препаратам клеток опухолей животных in vivo и клеток опухоли человека in vitro зависит от природы металла в комплексном полимерном соединении.
