Nazhir Capacity Analysis and Cooperation in Productive Waqf Management
Authors: Shiddiqy Muhammad Ash
Published: July 2022

Abstract: Waqf is an economic tool that can bring prosperity to the community. Therefore, good and proper management is required to realize the best interests of wakaf property. As the manager and developer of waqf property, Nazhir must have the ability and skills to manage waqf property. For this reason, special standardization is required to obtain a capable Nazhir based on the wealth of the waqf under management. When the management of the wakaf property works well and produces the best benefits, then these benefits can be used as the beneficiaries of the wakaf property to prosper the community. In the Law on Waqf No. 41 of 2004 and Government Regulation No. 42 of 2006 it has been stated about the responsibilities, roles, and functions of Nazhir. In addition to the law, there are also minimum requirements and abilities that an individual or group of Nazhir must possess. It is hoped that Nazhir in the future will have special abilities. Even though he did not have special skills, Nazir must have a strong desire to learn something related to the management, management and development of Waqf.                                                           Abstrak: Wakaf merupakan alat ekonomi yang dapat membawa kesejahteraan bagi masyarakat. Oleh karena itu, diperlukan pengelolaan yang baik dan benar untuk mendapatkan manfaat yang terbaik dari harta wakaf. Sebagai pengelola dan pengembang harta wakaf, Nazhir harus memiliki kemampuan dan keterampilan dalam mengelola harta wakaf. Untuk itu diperlukan standarisasi khusus untuk mendapatkan nazhir yang mumpuni berdasarkan harta wakaf yang dikelolanya. Ketika pengelolaan harta wakaf dapat berjalan dengan baik dan menghasilkan keuntungan yang sebesar-besarnya, maka manfaat tersebut dapat dijadikan sebagai penerima manfaat harta wakaf untuk mensejahterakan masyarakat. Pada Undang- Undang Tentang Wakaf No 41 Tahun 2004 dan Peraturan Pemerintah No 42 Tahun 2006 telah disampaikan tentang tanggungjawab, peran, serta fungsi Nazhir. Selain undang-undang, ada juga persyaratan dan kemampuan minimum yang harus dimiliki oleh individu atau kelompok Nazhir. Diharapkan Nazhir di masa depan akan memiliki kemampuan khusus. Meski tidak memiliki keahlian khusus, Nazir harus memiliki keinginan yang kuat untuk mempelajari sesuatu yang berkaitan dengan pengelolaan, pengelolaan dan pengembangan Wakaf.

Prosuming – energy sufficiency and rebound effects: Climate impact of changing household consumption patterns in Germany
Authors: Ouanes Nesrine , Kegel Jan , Wiesenthal Jan , Lenk Clara , Bluhm Hannes , Weiß Julika , Torliene Lukas
Published: July 2022

Changes in energy consumption patterns after becoming a prosumer household are rarely associated with negative environmental effects, as prosuming is intuitively assumed to be emission-reducing. This paper demonstrates the importance of sufficiency-oriented energy prosumer behavior for climate neutrality goals by quantifying GHG emissions for photovoltaic (PV) prosumers at the German household and energy system level. Based on the results, recommendations are derived for promoting energy sufficiency in prosumer households.
Почему девушки не выбирают STEM: гендерные различия в мотивационных ориентирах
Authors: Лебедева Наталия Владимировна , Вилкова Ксения Александровна
Published: July 2022

Активное развитие областей STEM (Science, Technology, Engineering, Mathematics) требует привлечения новых кадров. Однако в STEM наблюдается гендерный дисбаланс в сторону мужчин. В данной работе на основе смешанного дизайна мы изучаем, как именно юноши и девушки аргументируют важность прикладывания усилий для учебы и карьеры в STEM. В рамках количественного этапа мы анализируем данные опроса студентов, обучающихся в этой области (n = 2 192), для поиска гендерных различий в мотивационных ориентирах. На следующем этапе мы обращаемся к данным полуструктурированных интервью с семнадцатью студентами, что позволяет увидеть аргументацию юношей и девушек, которые прикладывают разные усилия для учебы в STEM. Рассматривая два этапа социализации (университет и карьера), мы зафиксировали, что мотивационные ориентиры выбора связаны со способностями к STEM и теми усилиями, которые студенты прилагают для успешной реализации в них. Юноши более уверены в своих способностях, аргументируя это наличием природного таланта и предрасположенности к успешной учебе в STEM. Девушкам же необходимо прикладывать дополнительные усилия для достижения успеха и в учебе, и в карьере. Однако, по их мнению, это зачастую не приводит к ожидаемому результату, и девушки чаще юношей задумываются о смене карьерной траектории после получения STEM образования. В свою очередь юноши после выпуска из университета склонны рассчитывать на высокую зарплату и быстрый карьерный рост. Полученные результаты фиксируют текущие проблемы гендерного дисбаланса в STEM, раскрывая особенности мотивационных ориентиров, и позволяют проводить более сфокусированные образовательные интервенции для закрепления девушек в данных областях.

Ценностные установки россиян: сравнение результатов онлайн- и офлайн-опросов
Authors: Корсунова Виолетта Игоревна , Соколов Борис Олегович
Published: July 2022

Использование онлайн-опросов имеет ряд преимуществ перед традиционными интервью: они дешевле, быстрее, доступнее, а также минимизируют влияние методологических факторов, таких как эффекты интервьюера. Отсутствие последних особенно важно при проведении исследований на сенситивные темы, так как в результате снижается доля социально одобряемых ответов. В то же время онлайн-опросы редко позволяют получить репрезентативные данные, что может приводить к ошибкам измерения и смещению содержательных оценок. В настоящем исследовании сравнивается качество данных офлайн- и онлайн-опросов в России. Для этого материалы двух онлайн-опросов («Ценности в кризисе» и «Онлайн-2018») сопоставляются с результатами седьмой волны Всемирного исследования ценностей в плане социально-демографических профилей и ценностных установок респондентов (на примере ценностей выбора и ценностей равенства). Показано, что данные онлайн-опросов репрезентативны по полу и возрасту, однако в них представлено меньше респондентов с низким уровнем образования и жителей сельской местности. Вместе с тем результаты говорят о наличии измерительной инвариантности факторной модели ценностных установок между двумя типами выборок, что позволяет напрямую сравнить полученные в ходе онлайн-исследований ценностные распределения с данными офлайн-опросов. В то же время в онлайн-выборках средние значения обоих ценностных индексов выше практически во всех социально-демографических группах.

Вместо университета — в колледж: что приводит успевающих одиннадцатиклассников в СПО?
Authors: Мальцева Вера Андреевна , Сальникова Ирина Евгеньевна , Шабалин Алексей Игоревич
Published: July 2022

Учеба в старшей школе чаще всего завершается поступлением в вуз, а колледж для одиннадцатиклассников является «вторичной» траекторией. Однако с середины 2010-х годов все больше выпускников 11 классов подают заявления в колледжи на фоне стагнирующего приема в вузы. В основе растущего спроса на СПО могут лежать как проблемы доступа к высшему образованию, так и изменение в восприятии желаемых и приемлемых послешкольных траекторий. В статье через призму социально-экономического неравенства и рационального действия исследуются особенности выбора образовательного маршрута одиннадцатиклассников, ставших студентами колледжей. Эмпирическую базу исследования составляет серия интервью со студентами, поступившими в колледжи в 2019—2020 гг. после окончания 11 классов и имевшими относительно высокую успеваемость в школе.
Исследование показало, что на выбор образовательной траектории студентов колледжей повлияло сочетание факторов. С одной стороны, выбор в пользу СПО оказался вынужденным шагом для одиннадцатиклассников в условиях снижения доступа к высшему образованию. Это следствие не только вторичных эффектов социально-экономического положения семьи и ее невысокого экономического ресурса, но и отсутствия продуманной стратегии поступления в вуз, наличие которой становится условием успешной прогрессии в высшее образование. С другой стороны, зафиксировано изменение в нарративе СПО: в случае «мягких» и цифровых профессий колледж начинает выступать непосредственной альтернативой вузу, каналом более быстрого и менее затратного овладения монетизируемыми профессиональными навыками. Таким образом, рост интереса к СПО можно интерпретировать и как вынужденно отложенное решение о получении диплома вуза, и как следствие нелинейности образовательных маршрутов молодежи.

В погоне за коллективным иммунитетом: прививочные стратегии россиян в контексте различных форм принуждения к вакцинации
Authors: Глазков Констанин Павлович
Published: July 2022

В фокусе анализа находятся прививочные стратегии россиян, которые выделены на основе представлений об эффективности массовой вакцинации, перспективах охвата ею  всего населения, ориентации на индивидуальный или коллективный иммунитет, а также наличия прививки либо планов привиться. Прививочные стратегии рассматриваются как индивидуальные решения, которые принимаются исходя из оценки текущей ситуации и интерпретации, что такое коллективный иммунитет и является ли он достижимым. В этом контексте коллективный иммунитет рассматривается не просто как стечение обстоятельств, а как результат масштабного коллективного действия. В отсутствии общеразделяемой позиции по достижимости коллективного иммунитета россияне в большей степени предпочитают рассчитывать на себя и свое здоровье. Вводя различные требования по вакцинации и ограничения для непривитых, государство пытается выступить в качестве координатора коллективного действия. Однако попытка навязать внешние требования расценивается людьми как форма принуждения к вакцинации. Оказанное на отдельно взятого индивида принуждение повышает шансы на вакцинацию конкретного человека, однако оказывает отталкивающий эффект на его окружение. Опираясь на данные всероссийского телефонного опроса (N = 1503, проведен Фондом «Общественное мнение») и восьми фокус-групп со сторонниками и противниками вакцинации из разных городов России, мы показываем, что различные формы принуждения к вакцинации повышают риск радикализации отношений между государством и обществом, а также способствуют еще большему разобщению индивидуальных и общественных интересов.

Integration of artificial intelligence and plasma steroidomics with laboratory information management systems: application to primary aldosteronism
Authors: Constantinescu Georgiana , Schulze Manuel , Peitzsch Mirko , Hofmockel Thomas , Scholl Ute I. , Williams Tracy Ann , Lenders Jacques W.M. , Eisenhofer Graeme
Published: July 2022

Objectives

Mass spectrometry-based steroidomics combined with machine learning (ML) provides a potentially powerful approach in endocrine diagnostics, but is hampered by limitations in the conveyance of results and interpretations to clinicians. We address this shortcoming by integration of the two technologies with a laboratory information management systems (LIMS) model.

Methods

The approach involves integration of ML algorithm-derived models with commercially available mathematical programming software and a web-based LIMS prototype. To illustrate clinical utility, the process was applied to plasma steroidomics data from 22 patients tested for primary aldosteronism (PA).

Results

Once mass spectrometry data are uploaded into the system, automated processes enable generation of interpretations of steroid profiles from ML models. Generated reports include plasma concentrations of steroids in relation to age- and sex-specific reference intervals along with results of ML models and narrative interpretations that cover probabilities of PA. If PA is predicted, reports include probabilities of unilateral disease and mutations of KCNJ5 known to be associated with successful outcomes of adrenalectomy. Preliminary results, with no overlap in probabilities of disease among four patients with and 18 without PA and correct classification of all four patients with unilateral PA including three of four with KCNJ5 mutations, illustrate potential utility of the approach to guide diagnosis and subtyping of patients with PA.

Conclusions

The outlined process for integrating plasma steroidomics data and ML with LIMS may facilitate improved diagnostic-decision-making when based on higher-dimensional data otherwise difficult to interpret. The approach is relevant to other diagnostic applications involving ML.
L-theanine induces skeletal muscle fiber type transformation by activation of prox1/CaN signaling pathway in C2C12 myotubes
Authors: Chen Xiaoling , Zhang Man , Jia Gang , Zhao Hua , Liu Guangmang , Huang Zhiqing
Published: July 2022

The aim of this study was to investigate the effect and mechanism of L-theanine (LT) on muscle fiber type transformation in C2C12 myotubes. Our data showed that LT exhibited significantly higher slow oxidative muscle fiber expression and lower glycolytic fibers expression. In addition, LT significantly increased the activities of malate dehydrogenase (MDH) and succinic dehydrogenase (SDH), and decreased lactate dehydrogenase (LDH) activity, the calcineurin (CaN) activity and the protein expressions of nuclear factor of activated T cell 1 (NFATc1), prospero-related homeobox1 (prox1), and calcineurin A (CnA) were significantly increased. However, inhibition of CaN activity by cyclosporine A (CsA) abolished LT-induced increase of slow oxidative muscle fiber expression and decrease of glycolytic fibers expression. Moreover, inhibition of prox1 expression by prox1-siRNA disrupted LT-induced activation of CaN signaling pathway and muscle fiber type transformation. Taken together, these results indicated that LT could promote skeletal muscle fiber type transformation from type II to type I via activation of prox1/CaN signaling pathway.

This study clarifies the data error rates optimization for OFC/OWC channels based on different transmission codes. These codes that are namely multi bits/symbol digital pulse interval modulation (DPIM), multi bits/symbol pulse position modulation (PPM), nonreturn to zero inverted (NRZI), 4 bit data symbol/5 bit code (4B5B), and Manchester for upgrading optical wired/wireless communication systems. The optical power through OFC/OWC channels, S/N ratio, the output power at the receiver side are stimulated with high bit transmission rates. The effects of coding complexity on the Q-factor, BER, optical power, and electrical received power are also stimulated using both DPIM and PPM coding.
Music, multimodality, and narrative viewpoint: Beowulf in performance
Authors: Page Connor
Published: July 2022

This article examines a solo musical/dramatic performance of the Old English poem Beowulf. Drawing on recent literature on multimodal communication, conceptual blending, and music cognition, it specifically discusses musical means of constructing and manipulating narrative viewpoint, exploring how sound and embodied performance influence and create the meanings of verbal narrative. Blending analysis, focused as it is on the integration of disparate input concepts into one blended space and the meaning-making potential of this process, lends itself naturally to the interaction of various modes of communication. In Benjamin Bagby’s Beowulf, the embodied, preformative resources of oral storytelling—particularly musical sound—structure narrative viewpoint in ways not afforded by the text alone, and thus support the process of story-construction. The famously ambiguous “Unferð Episode,” a dialogic exchange incorporating complex viewpoint phenomena and embedded narratives, exemplifies how such manipulation of viewpoint constrains and guides interpretation. As this article demonstrates, Bagby’s storytelling tools—verbal delivery, musical organization, gesture, posture—do not merely communicate a sequence of events but define the ways characters, narrators, and audience members negotiate, view and construe the stories constituted by those events.
Reliability in the identification of metaphors in (filmic) multimodal communication
Authors: Bort-Mir Lorena , Bolognesi Marianna
Published: July 2022

Research on multimodal communication is complex because multimodal analyses require methods and procedures that offer the possibility of disentangling the layers of meaning conveyed through different channels. We hereby propose an empirical evaluation of the Filmic Metaphor Identification Procedure (FILMIP, Bort-Mir, L. (2019). Developing, applying and testing FILMIP: the filmic metaphor identification procedure, Ph.D. dissertation. Universitat Jaume I, Castellón.), a structural method for the identification of metaphorical elements in (filmic) multimodal materials. The paper comprises two studies: (i) A content analysis conducted by independent coders, in which the reliability of FILMIP is assessed. Here, two TV commercials were shown to 21 Spanish participants for later analysis with the use of FILMIP under two questionnaires. (ii) A qualitative analysis based on a percentage agreement index to check agreement among the 21 participants about the metaphorically marked filmic components identified on the basis of FILMIP’s seven steps. The results of the two studies show that FILMIP is a valid and reliable tool for the identification of metaphorical elements in (filmic) multimodal materials. The empirical findings are discussed in relation to multimodal communication open challenges.

Optimization method for detection a flying bullet
Authors: Dong Tao , Gao Fengjia , Guo Quanmin , Chen Ding , Tan Linqiu , Gong Lei
Published: July 2022

With the rapid development of modern high technology and continuous improvement of production technology, stringent requirements have been imposed on modern barrel weapons in terms of precision, range, power, and mobility. This needs a substantial improvement and optimization of the detection equipment used to test the performance of barrel weapons. In the present work, an optimization method based on a light screen with a reflection for effectively and economically detecting bullets from barreled weapons within a large detection area is proposed. First, the detection principle of this system is described in detail. Next, the mathematical model of system detection performance is established. Then, the system is simulated, and the simulation results show the ability to realize the effective detection of a small projectile with a diameter of 5.8 mm through an area of 10 m × 10 m. The detection performance at different coordinates of the detection area is symmetrically distributed about the diagonal. Besides, the detection performance is improved with an increase in the bullet diameter and the laser power, respectively. Finally, an equal-scale reduction system with a detection area of 4 m × 4 m is constructed to perform a live ammunition shooting experiment. The distribution and variation of detection performance obtained experimentally are consistent with the simulation. Consequently, the proposed optimization method can meet the requirements concerning high detection performance, large detection area, and low cost.
The Economic Security of Small and Medium-Size Lithuanian Companies in the Context of the Covid-19 Pandemic
Authors: Kurienė Inga
Published: July 2022

The Covid-19 pandemic brought changes to every country’s economy. The increasing number of cases, the lack of equipment and supplies, and the disruption of production and services, led to strong measures to stop the spread of the virus. The pandemic also had a significant impact on the stability of existing businesses. The announcement of lockdown and the resulting restrictions influenced consumer behaviour, and companies have had to adapt quickly to current changes in order to maintain economic security. The suspension or restriction of activities affected the income, profits and business continuity of companies. The main purpose of this article is to analyse how the Covid-19 pandemic affected the economic security of small and medium-size Lithuanian companies. What impact did the pandemic have on the Lithuanian economy and the business dynamics of organisations? Using research methods, scientific literature and statistical data, a comparative analysis was performed to assess the impact of the Covid-19 pandemic on Lithuanian organisations. Based on the results, Lithuania was the least affected by the pandemic in the context of the European Union. However, there was a lot of uncertainty at the beginning of 2021; but the economy grew faster than expected. The volume of industrial production increased, retail and international trade grew. Despite the pandemic, growth was maintained in the manufacturing, wholesale and retail sectors. The impact of the pandemic was felt most in the services sector: accommodation and food service activities, the arts, entertainment and recreation, service and administrative activities.

This study presents the qualitative and quantitative evaluation of an educational programme that combines an online game and an outdoor activity with mobile learning in science education. The object of the study is to test the capacity of the programme to integrate science, culture and the environment, while transferring knowledge about marble. To this end, we align our theoretical orientation with the overall project design to devise an initial scheme that is pilot-tested by 155 university students of early childhood education and evaluated through a questionnaire. Qualitative data through participants’ feedback after the programme, observation notes and data from video recordings supplement the overall assessment. The results show high levels of satisfaction among the participants in terms of the quality of the activities, the distance between stations, the duration and structure of the programme, contact with marble, and the knowledge acquired.
A Theoretical Overview of the Impact of the Circular Economy on a State’s Economy
Authors: Ruginė Henrika , Viederytė Rasa
Published: July 2022

The Circular Economy (CE), as a possible transformation of economies, became very popular and widely discussed from 2015 when the worldwide importance of ecological preservation became highly in demand. To be able to implement the circular economy concept in various economies, its importance and prepared alterations to government regulations have to be widely discussed, and at the same time businesses and consumers have to prepare to live and work in the new paradigm. Consumers have to note the additional value of circular products and services, and their positive impact on health and the environment. Businesses will only start changing when they realise that new business models are available and they can keep profitability at the same level, even though consumption in general might change. The main aim of this article is to perform a theoretical analysis of the impact of the circular economy on a state’s economy. The main tools used for the research in the article were analysis, comparison and the summary of scientific literature. The article overviews possible changes and their impact on state economics in the future.
Opportunities for the Use of Steam Projects in Primary Years Classes: the Points of View of International Baccalaureate Teachers
Authors: Šmitienė Gražina , Kesylė Kamilė
Published: July 2022

Considerable changes to the Lithuanian education system are associated with higher academic achievements, the development of students’ critical thinking and research skills, and sustainable practices of integrated teaching and learning in science and mathematics. It is also acknowledged that STEAM (science, technology, engineering, the arts and mathematics) educational approaches address the objectives of integrated learning and teaching effectively. The same objectives are reflected in all the IB programmes. In the scientific discourse on the use of STEAM in science, there is a lack of research and examples of pedagogical practices with insights into different educational programmes and teachers’ experiences. The qualitative research (semi-structured interview) focuses on the points of view of teachers who implement the international baccalaureate primary years programme (IBPYP), and have a high level of project-based learning experience, of the possibilities of STEAM project implementation (6). The research findings reveal that teachers acknowledge the benefits of STEAM projects in terms of developing students’ research, critical thinking and independent learning skills, while implementing integrated teaching and learning strategies. The informants also recognise the importance of STEAM education in planning and organising integrated mathematics and science lessons.

Published: July 2022

The Arf GTPase family is involved in a wide range of cellular regulation including membrane trafficking and organelle–structure assembly. Here, we have generated a proximity interaction network for the Arf family using the miniTurboID approach combined with TMT‐based quantitative mass spectrometry. Our interactome confirmed known interactions and identified many novel interactors that provide leads for defining Arf pathway cell biological functions. We explored the unexpected finding that phospholipase D1 (PLD1) preferentially interacts with two closely related but poorly studied Arf family GTPases, ARL11 and ARL14, showing that PLD1 is activated by ARL11/14 and may recruit these GTPases to membrane vesicles, and that PLD1 and ARL11 collaborate to promote macrophage phagocytosis. Moreover, ARL5A and ARL5B were found to interact with and recruit phosphatidylinositol 4‐kinase beta (PI4KB) at trans‐Golgi, thus promoting PI4KB's function in PI4P synthesis and protein secretion.
Circulating oxysterols in Alzheimer’s disease: a systematic review and meta-analysis
Authors: Ademowo Opeyemi S , Dias Irundika H K
Published: July 2022

Despite decades of research, the cause and series of events underlying the advancement of Alzheimer’s disease (AD) have not yet been established. Lipid, especially cholesterol, levels have been proposed to be implicated in AD. Several studies have been undertaken and many are ongoing in different directions looking at the importance of circulating cholesterols and oxidised cholesterols in AD with inconsistent methods and results. This meta-analysis aims to systematically analyse available data describing the involvement of oxidised cholesterols in mild cognitive impairment (MCI) and AD. We conducted a systematic literature search of six databases MEDLINE (PubMed), BIOSIS (Web of Science), EMBASE (Elsevier), PsycNET, Scopus and Cochrane library for studies measuring oxysterols (24-hydroxycholesterol (24OHC); 26-hydroxycholesterol (26OHC) and 7-oxycholesterols) in serum or plasma from MCI/AD patients compared to age- and gender-matched cognitively normal controls. Data were analysed using the inverse variance and standard mean difference with random-effect analysis model at 95% CI for association between oxysterols and MCI/AD in Review Manager (RevMan) software version 5.4.1. Between January 2000 and April 2022, 175 studies were identified by two independent researchers out of which 14 met the inclusion criteria and were analysed with a total of 957 controls, 469 MCI cases and 509 AD cases. The standard mean differences between MCI/AD participants and controls did not show any difference in the oxysterol levels except for 26OHC level which was higher in AD but not statistically significant.

Authors: Diyarov Alan , Nursapina Nurgul , Matveyeva Ilona , Ponomarenko Oksana
Published: July 2022

The problem of high content of heavy metals in food has spread broadly over the world. The presented study suggests the minimization of heavy metal content in processed food due to different applied techniques such as the frying, boiling, steaming and sous-vide. Three main food products were chosen for investigation – Daucus carota subsp. Sativus (carrot), Solanum tuberosum (potato) and Allium cepa (onion). The concentration of heavy metals (Zn, Pb, Mn, Cd, Cu) was determined in samples investigated by atomic-absorption spectrometer. The health risk index (HRI) was calculated based on obtained data. In all investigated samples, high concentration of lead was identified among the heavy metals. The highest concentration of zinc, lead and manganese was determined in boiled Daucus carota subsp. Sativus, cadmium – in sous - vide Daucus carota subsp. Sativus, copper – in steamed Daucus carota subsp. Sativus. HRI values of cadmium for Solanum tuberosum samples were ranged from 6.8 to 7.1 and for lead are ranged between 3.4 and 4.9.

With the rise of new technologies, the growth of mass data processing and the digitization of newspaper archives, the individual information of people that is available in digital media has begun to cause great concern. It is not uncommon to see people constantly concerned about their personal information that appears on the internet, and it is that our image online worries us more every day. In this way, people who considered their reputation and honor affected by personal information hosted on the Internet and linked to their name and surname, due to issues that happened in the past or for which they were investigated, submitted their corresponding claims to European authorities. The authorities decided, through important resolutions and sentences that are exposed in the present work, and that mainly deal with the prevalence of the right to data protection of the interested party, the right to freedom of expression or the right to freedom of information that users have. It is sought through these lines to ensure that readers get to know the jurisprudential line that the European courts have on the prevalence of these rights.
Uso del tiempo en las relaciones de pareja y en el ejercicio de la maternidad y la paternidad en Costa Rica: un análisis crítico desde la perspectiva sociológica
Authors: Salazar Miranda Adriana , Sánchez Hernández Carolina
Published: July 2022

The objective was to develop an analysis of the existing asymmetries and gaps in the use of time between men and women, both in their relationship as a couple and in the exercise of motherhood and fatherhood, which means reviewing, on the one hand, the of daily tasks linked to unpaid domestic work, the care and upbringing of minors and, on the other hand, the free time dedicated to recreational, sports and personal care activities. The theoretical framework takes up the contributions of sociology and sexual political economy, where romantic love, idyllic motherhood and motherhood as punishment are problematized, in contrast to contemporary trends that reflect on the experience of pleasant motherhood. In methodological terms, it corresponds to a bibliographical research, where information collected by the National Survey of Time Use (abbreviated as ENUT from its original Spanish name, Encuesta Nacional de Uso del Tiempo) 2017 and other studies developed at the national level were used. It is verified that a social and sexual contract persists within couple relationships, which places women in a disadvantaged situation regarding the use of the most valuable resource: time. Since there are clear asymmetries between both sexes regarding days of unpaid work, care and upbringing. This is based on the romantic idea of love, which works to extract time and vital energy from women, proving that there is a supervised but little accompanied maternity; finally, some reflections are offered on the exercise of pleasant motherhood and, therefore, of responsible parenthood.
La ética del cuidado como forma de organización política feminista en Costa Rica
Authors: Guzmán Sierra Silvia Elena , López Céspedes Sharon
Published: July 2022

This article is the result of the systematization of the experience lived with 8 women from 4 feminist collectives, who, based on their situated knowledge, allow us to venture to reflect on an epistemology of care, and the political act of transferring care from the private sphere to the public space, which we understand as ethics of care. From their organizational praxis, three fundamental axes are drawn for these ethics, such as the linking organization, collective care and affectivity.
Determination of the effect of internal and external factors on the thrust spread of a cluster propulsion system

Published: July 2022

The thrust spread of a stand-alone rocket engine caused by external (the pressure and temperature of the propellant components at the engine inlet) and internal (spread in the geometry and operating conditions of the engine units and assemblies) factors is known from experimental tests or can be computed by a known procedure. As a rule, liquid-propellant propulsion systems (LPPSs) of launch vehicle lower stages include a cluster of several engines, whose thrust spread cannot often be determined from firing tests due to limited capabilities of bench equipment. The aim of this work is to develop an approach to determining the thrust spread of an LPPS comprising a cluster of two and more engines. For a multiengine propulsion system, this methodological approach also includes the development of a mathematical model of engine interaction in an LPPS and calculations of an LPPS startup at different combinations of spread in the external and internal factors in cases where the parameter spreads of all engines are both identical and different. For an LPPS with two engines and a common oxidizer feed pipeline, the paper gives an example of calculating the effect of external and internal factors on the thrust spread of each engine and the LPPS as a whole during an LPPS startup. . It is shown that the calculated spread of the 90 percent thrust (combustion chamber pressure) time lies in the range – 0.0917 s to +0.0792 s (engine 1) and –0.0941 s to +0.0618 s (engine 2). The calculated variations of the combustion chamber pressure (engine thrust) from its nominal value lie in the range –6.2 percent to +7.0 percent (engine 1) and -6.8 percent to +6.3 percent (engine 2). The calculated spreads of the 90 percent thrust time and the thrust for the LPPS as a whole are far smaller (about by 40 percent) and lie in the range – 0.0733 s to +0.0457 s for the time and – 4.8 percent to +4.8 percent for the thrust (about the nominal thrust). Using Pearson’s chi-squared test, an estimate is obtained for the goodness of fit of the anticipated theoretical distributions of the 90 percent thrust time spread and the steady thrust spread to the obtained statistical ones both for the two engines and for the LPPS as a whole.
Potential Protective Role of 14-3-3 Protein in Pathological Cardiac Hypertrophy Through The Regulation of Endoplasmic Reticulum Stress: Role of Calreticulin

Published: July 2022

Introduction: 14-3-3 protein plays an important role in protecting cardiac cells from hypertrophy and endoplasmic reticulum stress during pressure overload elicited by aortic banding (AB) surgery; however, the relation among these protective roles is largely unknown. Methods: We investigated the in vivo role of 14-3-3 protein in two protocols involving C57/BL-6 mice and dominant negative (DN) 14-3-3η mice subjected to three- or seven-days pressure overload stimulation by applying AB surgery. The protein expressions of cardiac hypertrophy and ER stress markers, including atrial natriuretic peptide (ANP), galectin-3, glucose-regulated protein (GRP)78, calreticulin as well as 14-3-3 protein was analyzed by western blot. Results: Three- or seven-day pressure overload stimulation significantly increased the heart weight/body weight (HW/BW) ratio; cardiomyocyte diameter; and the protein expression levels of ANP, GRP78 as well as 14-3-3 in the C57/BL-6 mice. Partial inactivation of 14-3-3 protein in the DN 14-3-3η mice significantly increased the protein expression of ANP, Galectin-3, GRP78, and calreticulin after three- or seven-days AB surgery. Conclusion: These results suggest that 14-3-3 protein, as a molecular chaperone, protects against pathological cardiac hypertrophy, at least in part, by maintaining the normal ER function through the regulation of GRP78 and calreticulin.
Procesamiento GNSS en el Marco Geodésico CR-SIRGAS: influencia de las épocas de observación y referencia
Authors: Moya Zamora Jorge
Published: July 2022

Las observaciones satelitales derivadas de las constelaciones GNSS están totalmente correlacionas con el instante en la que se realizan las mediciones, sin embargo, los usuarios pueden trasladarlas a diferentes épocas siempre y cuando se cuente con los parámetros necesarios. La calidad de las mediciones GNSS en principio se verá afectada al llevarlas a una época diferente de la original. En el caso del marco geodésico nacional de Costa Rica CR-SIRGAS su época de referencia actual es t0 = 2019,24 [1] pero la georreferenciación de la información espacial para efectos catastrales debe estar en la época de referencia tk = 2014,59 [2]. Se realizó un proceso de ajuste amarrado en la época ti = 2021,53 usando como observaciones las líneas base de cada punto nuevo a un máximo de cuatro estaciones CR-SIRGAS con sus respectivas coordenadas semanales finales. Después se repitió este ajuste usando los mismos, pero como coordenadas de vínculo las oficiales de la época de referencia t0 implicando una marcada disminución en el peso original de las observaciones en un factor de 1,5 a 9,5. Además se logró cuantificar las discrepancias en las coordenadas, exactitudes y observaciones ajustadas directamente en esta época t0. Finalmente se aplicaron los parámetros de transformación oficiales dados por [1] para llevar el conjunto de coordenadas de la época t0 a la época tk.

Rethinking call centers
Authors: Tovar Johanna
Published: July 2022

Call centers have been critiqued in academia and the media for widespread standardization. This paper argues that although this critique of working conditions is well-intended, it has led to unwanted stigmatization of not just call center work but also of call center agents. Much has been published on call centers, but the stigma this work entails and the effect this has on agents on and off the phone has been overlooked. This paper applies Goffman’s notion of stigma to data collected through long-term ethnography and interviews with over seventy call center agents in a London call center. I show how agents experience, manage, and resist stigma. The analysis reveals that agents attempt to hide where they work by adopting different accents and avoiding specific lexis associated with call center language. I conclude by suggesting potential avenues for reducing the stigma of working in a call center, e.g. shifting the dominant discussion in academia beyond debates surrounding standardization.
Roselle Plant Pigments As Natural Photosensitizers For Dye Sensitized Solar Cells: the Effect of Tin Oxide Blocking Layer on the Photoelectric Properties.
Authors: Amaechi Chukwuwendu J. , Ogbonda Clement N.
Published: July 2022

Dye sensitized solar cells (DSSCs) assembled on titanium dioxide (TiO2) synthesized with plant dye extracted from dried Roselle plant pigments were fabricated. The dye extract and active layers were characterized using a (UV 752) ultraviolet-visible-Near Infra-Red (UV-VIS-NI)
spectrophotometer, at the wavelength interval of 250 nm to 1100 nm, while the Tauc model was used to obtain the optical band gap. The absorption coefficient and behaviour of the extinction coefficient was investigated. The current and voltage features of the dye sensitized solar cell fabricated
with the synthesized TiO2 Photoanode were analysed. The optical band gap of the dye sensitized solar cells fabricated were 2.6eV, 2.8eV and 3.0 eV respectively, while the conversion efficiency of the dye sensitized solar cells was 1.34%, 1.32% and 2.9%.
