Background
Although vitamin D concentration is reportedly associated with the pathogenesis and pathology of systemic lupus erythematosus (SLE), benefits of vitamin D supplementation in SLE patients have not been elucidated, to our knowledge. We investigated the clinical impacts of vitamin D supplementation in SLE.

Methods
A cross-sectional analysis was performed using data from a lupus registry of nationwide institutions. We evaluated vitamin D supplementation status associated with disease-related Systemic Lupus International Collaborating Clinics/American College of Rheumatology Damage Index (SDI) as a parameter of long-term disease activity control.

Results
Of the enrolled 870 patients (mean age: 45 years, mean disease duration: 153 months), 426 (49%) received vitamin D supplementation. Patients with vitamin D supplementation were younger (43.2 vs 47.5 years, P < 0.0001), received higher doses of prednisolone (7.6 vs 6.8 mg/day, P = 0.002), and showed higher estimated glomerular filtration rates (79.3 vs 75.3 mL/min/1.73m2, P = 0.02) than those without supplementation. Disease-related SDI (0.73 ± 1.12 vs 0.73 ± 1.10, P = 0.75), total SDI, and SLE Disease Activity Index (SLEDAI) did not significantly differ between patients receiving and not receiving vitamin D supplementation. Even after excluding 136 patients who were highly recommended vitamin D supplementation (with age ≥ 75 years, history of bone fracture or avascular necrosis, denosumab use, and end-stage renal failure), disease-related SDI, total SDI, and SLEDAI did not significantly differ between the two groups.

Conclusions
Even with a possible Vitamin D deficiency and a high risk of bone fractures in SLE patients, only half of our cohort received its supplementation. The effect of vitamin D supplementation for disease activity control was not observed.

Maximizing firm value is the main goal of the firm. The high value of the firm indicates that the firm is able to maintain business continuity and can improve the welfare of shareholders. So that investors are interested in investing their capital in firm’s that have high firm value. Several previous studies have shown different results regarding the value of the company. Therefore this study was conducted to re-examine the theory of the firm value, and to determine the effect of company size, leverage, and profitability on the value of the main board companies listed on the Stock Exchange in the 2014-2018 period.This study uses a causal associative method with a quantitative approach, the data used are secondary data from the reports of the main board firms listed on the Indonesia Stock Exchange in the 2014-2018 period obtained by 107 firms with purposive sampling techniques and analyzed using eviews 10. Data testing techniques used is descriptive statistical analysis, classic assumption test, correlation test, regression test, coefficient of determination analysis, and hypothesis testingThe results of the analysis show that the firm size variable produces a tcount (1.222) <ttable(1.974), and a significant value (0.221> 0.05) it means that the firm size partially has no effect on the firm value. Leverage variable produces a tcount (6,020)> ttable(1,974), and a significant value (0,00 <0.05), it means that leverage partially has a significant effect on the firm value. The profitability variable produces a tcount(12,965)> ttable(1,974), and a significant value (0,00 <0.05), it means that profitability has a partially significant effect on firm value. From testing all the independent variables simultaneously obtained fcount(61.079)> ftable(2.62), and the level of significance (0.00 <0.05). This shows simultaneously the variables of firm size, leverage, and profitability together affect of the firm value main board contained on the Indonesia Stock Exchange period 2014-2018.
On ideals in group algebras: An uncertainty principle and the Schur product
Authors: Borello Martino , Willems Wolfgang , Zini Giovanni 
Published: June 2022

Abstract
In this paper, we investigate some properties of ideals in group algebras of finite groups over fields.
First, we highlight an important link between their dimension, their minimal Hamming distance and the group order.
This is a generalized version of an uncertainty principle shown in 1992 by Meshulam.
Secondly, we introduce the notion of the Schur product of ideals in group algebras and investigate the module structure and the dimension of the Schur square.
We give a structural result on ideals that coincide with their Schur square, and we provide conditions for an ideal to be such that its Schur square has the projective cover of the trivial module as a direct summand.
This has particularly interesting consequences for group algebras of 𝑝-groups over fields of characteristic 𝑝.
The Drivers of the Nutritional Quality and Carbon Footprint of School Menus in the Paris Area

Published: June 2022

Abstract
Public school food procurement has been identified as a key lever in the transition towards sustainable food systems. In this study, we assess the nutritional quality and the carbon footprint of 2020 school menus served in 101 municipalities in the inner suburbs of Paris. In this sample, school canteens menus meet an average 8.2/15 (min = 4, max = 14) adequacy score to the regulatory nutritional quality frequency criteria and their carbon footprint averages at 1.9 (min = 1.2, max = 2.6) kgCO2e/day. The nutritional and environmental qualities of canteen menus were not correlated with each other. In-house canteens have a significantly higher nutritional quality – 0.7 more points – and so do larger canteens. The carbon footprint significantly decreases with an increasing education level of the population and, for in-house canteens, it also decreases by 0.16 kgCO2e/day with a ten-fold increase in canteen size and by 0.0035 kgCO2e/day per percent of left-wing vote, breaking even with delegated canteens above 3500 enrolled children and 53% of left-wing vote respectively. The frequency of certified food (mean = 18%, min = 0%, max = 51%), a cornerstone of the 2018 national law aiming at more sustainable institutional catering, has no impact on our indicators of nutritional quality and carbon footprint. The substantial variations between canteens in both nutritional and environmental qualities suggests that there is room for improvement on both ends.
Preferences for the Farmer-Owned Label: Evidence from Cheese Consumers in the United States
Authors: Grashuis Jasper 
Published: June 2022

Abstract
Driven by external developments like industry consolidation and price volatility, organized farm producers seek opportunities to generate rent in the value-added segment of the agri-food industry. Given inherent constraints with cost efficiency and product quality, farm producer organizations (FPOs) may use branding to pursue differentiation. An opportunity is facilitated by the farmer-owned label, which constitutes an ownership signal to consumers. However, empirical evidence of the economic viability of the farmer-owned label is limited. Following a choice experiment with 296 cheese consumers in the United States, we specify a random parameter logit model and find a positive willingness-to-pay for the farmer-owned label which is in excess of private and corporate brands in the same product category. In the final model, the mean willingness-to-pay is estimated at $1.74. While the farmer-owned label is proven to be economically viable in a competitive product category, consumer preferences are heterogeneous. Also, there is no compatibility between the farmer-owned label and indicators of family ownership and product origin.
Persistent Reflection, Artistic Conception: A Review of One Second
Authors: Hu Ke 
Published: June 2022

Abstract
The uniqueness of One Second (Yimiaozhong, 2020) lies in its two-fold expression: it first tells the story of a father at an exceptional point in history who breaks out of jail to look for, then view a clip of his daughter. Second, through the form of cinema, it reflects on the relationship between the movie and audience, exploring the particularities of film to convey the auteur’s sentimentality for the medium. This is a simple but innovative film with rich connotations, diverse in its intentions.
The topology of crystalline matter
Authors: Hoffmann Frank 
Published: June 2022

Abstract
In this chapter an overview is given in which way framework-like crystalline compounds can be regarded as nets, how a net is derived out of a particular crystal structure, what nets actually are, how they can be appropriately described, what the characteristics of nets are, and how this topological approach helps to categorize framework compounds. Finally the term reticular chemistry is explained and a number of examples are given how the topology-guided approach opens up new possibilities to intentionally develop new framework structures on a rational basis.

Abstract
In the course of finding new antifungal natural compounds against plant pathogens, the methanol extract of Desmodium triflorum was investigated phytochemically. From n-butanol-soluble fraction, seven compounds (1–7) were isolated and structurally elucidated. Of which, six compounds belong to flavone 6- or 8-C-glycoside class (1–6). Three major compounds (1–3) exhibited moderate in vitro antifungal activity against Sclerotium rolfsii, Fusarium oxysporum f. sp. cubense, and Phytophthora palmivora. Compound 1 (IC50 = 162.1 μg/mL) was most active against S. rolfsii in a dose-dependent manner. At 300 μg/mL, compounds 1 and 2 significantly inhibited P. palmivora, whereas compound 3 lacked effectiveness. In addition, the nanoemulsion of the methanol extract with a droplet size of 12.2 nm displayed an excellent inhibition against S. rolfsii and P. palmivora compared with the normal extract. The presence of 1 (0.846%) and 2 (0.759%) in the methanol extract may attribute to the antifungal activity of D. triflorum. These results proved the potential of D. triflorum and its C-glycoside flavonoids against phytopathogenic fungi for the first time. Besides, an enhancement in the effectiveness of nanoemulsion containing D. triflorum extract against the fungi was confirmed. The structural characteristics of 1 and 2 could be considered to develop new fungicidal substances in the future.

Qardhawi's opinion on the 2009 zakah disbursement model related to the empowerment of productive aṣnāf has encouraged the development of productive zakah in poverty alleviation. This study aims to examine the effect of intentions, opportunities, and resources on successful aṣnāf entrepreneurs. The method used is the mono method, namely quantitative research. Data was obtained through a survey using purposive sampling. Primary data were examined using the PLS-SEM method and the SmartPLS application. This study found that the intention and opportunity factors had a positive and significant effect on the success of aṣnāf entrepreneurs. Meanwhile, resources have a negative impact on the success of aṣnāf entrepreneurs. This is evidence that the zakah resources given to aṣnāf entrepreneurs must be optimized so that they can have a significant impact. This finding provides recommendations to zakah management entities and policy makers to be able to increase the contribution of zakah funds in poverty alleviation through the aṣnāf entrepreneurial program.

Sharia Financial Institutions Compliance Towards Islamic Principles in Performing Intermediation Functions
Authors: Usman Mizaj Iskandar 
Published: June 2022

This study aims to determine the factors of non-compliance with Islamic principles in Islamic Financial Institutions (IFIs). This article argues that IFIs must comply with Islamic principles based on the DSN-MUI fatwa, even though in the Indonesian legal hierarchy, DSN-MUI fatwas are not binding. IFIs show ambiguity in complying with Islamic principles when carrying out their intermediation function. Several other factors also cause IFIs' lack of compliance with sharia principles. These include the lack of applicability of the DSN-MUI fatwas, the conflict of interest of the Sharia Supervisory Board (SSBs), and competency issues among SSBs members. To address these issues, it is necessary to strengthen the regulations that make DSN-MUI an authoritative institution in establishing the sharia principles and the fatwas methodology. Thus, the fatwas are more applicable and avoid ambiguity. Furthermore, SSBs need re-structurization to be independent internal supervisory agencies. AbstrakPenelitian bertujuan mengetahui faktor-faktor ketidakpatuhan lembaga keuangan syariah (LKS) pada prinsip-prinsip Islam. Artikel ini menyebutkan LKS harus mematuhi prinsip-prinsip Islam sesuai fatwa DSN-MUI, walaupun dalam hierarki hukum Indonesia, DSN-MUI bukanlah sebuah lembaga otoritatif yang menerbitkan hukum mengikat. LKS tampak ambigu dalam mematuhi prinsip-prinsip Islam saat menjalankan fungsi intermediasinya. Ketidakpatuhan LKS kepada prinsip-prinsip syariah juga disebabkan oleh beberapa faktor lain, seperti: tidak aplikatifnya fatwa DSN-MUI; munculnya konflik kepentingan DPS; dan masalah kompetensi anggota DPS. Untuk mengatasi masalah-masalah tersebut, perlu adanya perbaikan regulasi yang menjadikan DSN-MUI sebagai lembaga otoritatif, agar fatwa yang dikeluarkan lebih aplikatif dan tidak menimbulkan multi tafsir. Sementara dari sisi DPS, perlu adanya regulasi merestrukturisasi organisasi DPS dengan menepatkannya sebagai lembaga pengawas internal yang independen.
Інтеграція жінок у збройні сили як виклик престижу військової професії
Authors: Храбан Тетяна , Вигівська Оксана 
Published: June 2022

Мета статті – з’ясувати вплив процесу інтеграції жінок у Збройні сили України на еволюціонування престижу професії військовослужбовця. В дослідженні використовувався дискурс-аналіз як метод дослідження, який історично фокусуються на змістовних особливостях комунікації, обумовлених системою владних відносин та інститутів влади. Матеріалом цього дослідження стали 677 коментарів, які були розміщені в 2021 році в українському секторі соціальної мережі Фейсбук і які включають концепти «жінка» і «армія» як центральні ідеї дискурсу. Було доведено, що процес інтеграції жінок у Збройні сили України, з яким пов’язана зміна ґендерного складу на користь жінок, значно впливає на оцінку престижу професії військового.
З одного боку, це дає поштовх для створення в українському секторі соціальних мереж претензійного образу жінки-захисниці Батьківщини, який відрізняється неабиякою часткою нарцисизму, вірою у свою винятковість, перевагою над чоловіками, і є шкідливою та руйнівною силою відносно престижності професії військового, оскільки піддає сумніву морально-етичні норми, які визначають ціннісну орієнтацію світогляду офіцера і відображені у Кодексі честі офіцера Збройних сил України. З іншого боку, оцінка професійного престижу втілює культурні переконання та стереотипні образи, а також пов’язані з ними передсуди та упередження. Зображення жінок-військовослужбовців відображає патріархальні стереотипи і дискримінацію по відношенню до жінок. Такі ґендерні стереотипи, як обов’язковість силової витривалості в професіях, де домінують чоловіки; диспаритет чоловіків та жінок в інтелектуальному плані; наявність у жінки якостей, наприклад, легковажності та емоційності, які несумісні із професією військового; більша соціальна цінність чоловіка у порівнянні з жінкою, у період проведення політики інтеграції жінок до армії завдають шкоди престижності професії військового, оскільки вони піддають сумніву такі важливі для професійного престижу фактори, як кваліфікація, компетентність, професіоналізм, соціальна корисність всього особового складу України без винятку. Пряме сексуальне опредметнення жінок транслює ідею, що вона в армії – це лише ресурс для розваг і задоволення сексуальних потреб. За значного збільшення кількості жінок, які служать у Збройних Силах України, така ідея є згубною для престижності професії військового, її руйнівний ефект спрямований на підрив поваги, шанування, соціальної довіри як факторів професійного престижу. До таких же негативних наслідків щодо престижності професії військового призводять випадки, коли вступ жінок до лав ЗСУ мотивується такими факторами, як меркантильність та пошук матеріальної вигоди, що може прикриватися лицемірством та тактикою подвійних стандартів.
Автономность и зависимость как факторы создания постиндустриальных социальных пространств
Authors: Белоус Вікторія 
Published: June 2022

Цель данной статьи - раскрыть новые формы взаимосвязи социального пространства и индивидуального субъекта, которые возникают в рамках компьютерной революции и становления постиндустриального общества.
Методы исследования – вскрытие связи исторического и логического, выявление основных диалектических противоречий, использование компаративистского, структурного и герменевтического подхода.
Новизна: использование категорий автономности и зависимости как характеристик, которые позиционируют индивидуального субъекта в социальном пространстве. Автономность определена как целостность субъекта в совершении любой формы выбора. Зависимость понимается нами как невозможность для субъекта совершения выбора без внешних воздействий (указаний или дополнительной информации).
Также, введено понятие «секторального субъекта» - это «слабый» искусственный интеллект (ИИ), который создан для выполнения узкого набора функций, но уже может выполнять отдельные социальные практики и тем воздействовать на структуры социального пространства. «Секторальные субъекты» позволяют создавать локусы/поля социального пространства, существующие без прямой поддержки индивида как работника.
Установлено, что «слабые» ИИ могут снижать или повышать приватность субъекта, что воздействует на его зависимость. А, также, поддерживать псевдодискуссионные практики взаимодействия с индивидом, которые снижают его автономность. Вместе с тем, они способны увеличивать автономность индивида, автоматически выполняя часть его социальных практик. Также, предложена схема, которая демонстрирует соотношение целостности/секторальности субъекта и унитарности/локусности его социального пространства.
Выводы: Виртуализация социального взаимодействия приводит к снижению роли территориального расположения индивида, но не приводит к полному отказу от приватного. Поддержание приватности является необходимым условием автономности субъекта. Приватным становится не жилище или физиология индивида сами по себе, а взаимодействие субъекта с подчиненными ему «секторальными субъектами», а также контроль над качествами части локусов/полей социального пространства. В таких условиях сохранение автономности субъекта потребует освоения индивидом целого набора практик для поведения в новом социальном пространстве.
