Authors:   Lviv Polytechnic National University, Shkoropad Yu. , Beshley M. , Beshley H. , Holubets V.
Published: June 2023

The development of Mobile Cyber-Physical Systems (MCPS) is a promising research and development direction for many industries, such as manufacturing, healthcare, home automation, and many others. That is why a prototype MCPS based on a smartphone has been developed to collect, process, and transmit data from various devices and sensors in real-time, anywhere. The architecture of a mobile cyber-physical system for monitoring climatic parameters with telegram notifications has been designed. An algorithm for intelligent analysis and optimization of data transmission processes has been proposed for the developed MCPS prototype. The advantage of the developed system is the ability to determine the priority of monitoring parameters, which allows for a quick response to critical temperature changes at the object where the measurements are taken. Additionally, a unique method for measuring end-to-end data transmission delay using a timestamp in the packet header metadata has been implemented. This method enables the determination of the processing time of each component of the MCPS and, in case of exceeding the norms, automatically notifies about the necessary control decisions. Supporting such a method in MCPS is a particularly effective solution for monitoring the quality of real-time service delivery in critical infrastructure objects. Based on the conducted research, it has been established that the proposed algorithm for intelligent data analysis and optimization has reduced the number of messages by 3 times and the amount of transmitted information by 2.3 times. In the future, the developed system, in combination with artificial intelligence, will ensure reliable and high-quality data transmission even in unpredictable situations, making it a promising solution for improving the quality of life and the efficiency of smart infrastructures in various fields.

INVESTIGATION OF THE INFLUENCE OF INSTABILITY OR INACCURACY OF MODULATOR AND DEMODULATOR PARAMETER SETTING ON THE PROBABILITY OF ERROR WHEN RECEIVING DATA
Authors:   Lviv Polytechnic National University, Horbatyi I. , Tsymbaliuk I. , Bobalo Yu.
Published: June 2023

The structural diagrams of devices for the forming and processing of modern amplitude-phase-manipulated signals are considered. The parameters of the modulator and demodulator have been identified, the instability or inaccuracy of whose setting significantly increases the probability of an error when receiving data. Based on the results of the research, recommendations were made regarding the necessary values of the modulator and demodulator parameters to reduce the probability of a symbol error when receiving data. The reproducibility of bit combinations to the points of the 8-AMMC signal constellation (8-position amplitude modulation of many components) is proposed to minimize the probability of a bit error in information communication systems when receiving data.

Analyses the Construction of the Indonesian Ulema Council Fatwa on the Halalness of the Sinovac Covid-19 Vaccine using the Jasser Auda’s Perspective of Islamic Law Development Models
Authors: Abduh Muhammad , Abadi Khafid , Islamy Athoillah , Susilo Adib
Published: June 2023

The spread of hoax news related to whether it is safe or not and whether or not the use of the Covid-19 vaccine is lawful has created a pro-contra attitude among the Indonesian people towards the Covid-19 vaccination program. For this reason, the Indonesian Ulema Council (MUI) has issued a fatwa to provide legal enlightenment on the halal use of the Covid-19 vaccine. This study examines in depth the construction of the fatwa and identifies the Islamic law development model used in constructing the fatwa. This research is purely philosophical normative and uses the models of Islamic legal development proposed by Jasser Auda. The results of the study conclude that the construction of the MUI fatwa on the halalness of the Sinovac vaccine had used a holistic model of Islamic law. This is indicated by some characteristics inherent in the construction of the fatwa namely : (i) the wholeness and multidimensional character, which is indicated by the use of universal textual arguments ('aam). (ii) the purposive character, which isindicated by the use of various fiqh rules emphasizing the realization of benefit as the basis and orientation of legal determination. (iii) the openness characterwhich is indicated by the acceptance of the health and medical science principles which incidentally is outside the field of Islamic law

Authors: Yanto Oksidelfa
Published: June 2023

This study discusses the criteria for actions that can be classified as acts of religious blasphemy. The aim is to find out in-depth the types of actions that can be classified as criminal acts of blasphemy, as well as legal provisions and sanctions against perpetrators who intentionally commit such acts. This research is descriptive qualitative using a normative juridical approach. To obtain data in viewing the issues discussed, the authors use normative juridical research methods through library research using secondary data. The results of the study show that the acts of religious blasphemy include all kinds of slanderous actions aimed directly at the religion professed, either orally or in writing, regardless of whether it will endanger public order or not, with the aim that people do not adhere to a particular religion. In the realm of criminal law, the case of blasphemy is a form of a pure criminal event whose perpetrators can be given legal sanctions. The legal sanctions for perpetrators according to the Criminal Code can be sentenced to 5 (five) years in prison
Online Marriage During the Covid-19 Pandemic: A Study of the Fatwas in Egypt, Iraq, Syria, and Saudi Arabia
Authors: Hakim Abdul , Qodsiyah Bagus Haziratul
Published: June 2023

Online Marriage During the COVID-19 Pandemic: A Study of the Fatwas in Egypt, Iraq, Syria, and Saudi Arabia. Online marriage is a new social phenomenon that has emerged since the arrival of the COVID-19 virus outbreak in all corners of the world. This phenomenon is widely discussed by people everywhere and is motivated by the desire to carry out pre-planned marriages and not wanting to postpone them. This study aims to discuss the above social phenomena from the point of view of fiqh, maqāshid al-sharīa, and fatwas in several Muslim countries. This type of research is qualitative in the form of a literature study using a conceptual and socio-legal approach. Based on the results of the study, it can be concluded that the views of fiqh and fatwas in Muslim countries regarding online marriage are divided into two: Some allow it because they regard virtual meetings as meetings in one place (ittihād al-majlis) and consent and qabūl can be witnessed by both witnesses; but some forbid it because there is no physical and essential ittihād al-majlis, there are no witnesses, and the possibility of audio-visual manipulation. Viewed from the maqāshid al-sharīa perspective, online marriage is also not suitable because the purpose of marriage may not be realized.
Zhihar Contextualization in Indonesia: an Anthropo-Linguistic Study
Authors: Siradjudin Azmi , Maliki Ibnu Akbar
Published: June 2023

The law of zhihar (equating wife to her mother) is closely related to Arabic culture, where the Qur'an was revealed. In Indonesia, zhihar law cannot be enforced because of social norms differences. This article examines the contextualization of zhihar in Indonesia. The aim is to examine the meaning of zhihar in the Qur’an which is then applied in the context of Indonesian culture. Specifically, the contextualization includes the use of language in the zhihar which is then linked to the existing cultural context. This research is purely a literature study using qualitative methods. The approach used is the sociology of language, or more specifically it can be called the anthropo-linguistic approach. The results of the study show that respect is deeply embedded in family life in Indonesia. This means that the husband may equate his wife with his mother-in-law; But not forbid himself against his wife, only to praise and respect her. From the perspective of the sociology of language, this compliment is a reflection of cultural values that have long lived in Indonesian society. The mufassirs (the commentators of al-Qur'an) stated that this action is not zhihar because the lafadz zhihar requires the intention to forbid husband and wife relations. Therefore, it is necessary to conduct an in-depth study dealing with the axiological value of the law of zhihar in the Qur'an which is linked to socio-cultural aspects.
Reasons For the Permission of Replacement of Wakaf Assets (Istibdal Waqf) in Indonesian Regulations: An Interpretative Study
Authors: Musthafa Musthafa , Bin Hj Abdullah Luqman , Binti Pauzi Nurhidayah
Published: June 2023

Government regulations regarding the implementation of istibdal waqf (replacement of waqf assets) aim to ensure the benefit of waqf assets, so they can last longer and be utilized according to their designation. Unfortunately, an explanation of the reasons for the permissibility of istibdal waqf in Government Regulation 42 of 2006 concerning the Implementation of Law No. 41 of 2004 concerning waqf is not found in the regulation. This obscurity can confuse understanding the reasons for the regulation's permissibility of istibdal waqf. This study aims to explain the reasons for the permissibility of istibdal waqf in the regulation. Thus, from the results of this study, a complete understanding can be obtained dealing with the permissibility of istibdal waqf and preventing the emergence of differences in understanding that can harm waqf assets. This research is classified as library research using a legal interpretation approach. This study found that the reason for the permissibility of istibdal waqf in point an in article 49 (2), Government Regulation of the Republic of Indonesia. No. 42 of 2006 concerning the Implementation of Law Number 41 of 2004 concerning Waqf refers to Government Regulation No. 19 of 2021 concerning the Implementation of Land Procurement for Public Interests. At the same time, the explanation for the permissibility of istibdal waqf in point b relates to waqf assets that cannot be used or utilized following the waqf pledge. Furthermore, the permissibility of istibdal waqf in point c relates to waqf assets that can still be used or utilized.

Published: June 2023

Rapid technological advances are affecting the greater use of electrical energy. One of the devices that can generate electrical energy is a generator. Testing the characteristics of the generator required a drive motor to rotate the generator shaft. This research aims to create a three-phase input power measurement system for driving a motor. The method of measuring input power is by measuring the current and voltage of each phase. The power is obtained from the multiplication between current and voltage. The system consists of current sensors, voltage sensors, a signal conditioning circuit, and an Arduino Mega microcontroller for data processing. The system is equipped with a graphical user interface, data storage, and application. The generator input power measurement system has been created and tested. The measurement system has successfully measured the input power of the generator's driving motor, which in real-time is displayed on the trend graph via the graphical user interface on the laptop. The input power measurement data on the three-phase generator and the time data have been successfully stored inside the micro-SD. The average error of the voltage reading is 2% compared to the measurement of the reference voltmeter. The current reading error was 2% compared to the reference meter ampere measurement.
Lectura, biografía y autobiografía en Allá en lo verde Hudson y Si la Argentina fuera una novela (La novela nacional), de Arnaldo Calveyra
Authors: Maranguello Carolina
Published: June 2023

Entre fines de la década de 1980 y mediados de la siguiente, Arnaldo Calveyra escribe dos libros en los que recupera la figura de William Henry Hudson: Si la Argentina fuera una novela (2000) y Allá en lo verde Hudson (2012), retomando fragmentos de Far Away and Long Ago (1918), las memorias del escritor, entre otras referencias a ensayistas y escritores de la tradición nacional. El trazado fragmentario de la biografía de Hudson le permite a Calveyra inscribir su propia historia personal, indagar su linaje familiar (a partir de su bisabuelo exiliado del rosismo) y abrir espectralmente las coordenadas espaciales (entre París y las lomas entrerrianas) y temporales (desde el siglo XX al siglo XIX). Considerando las recurrencias temáticas y tonales, pero también las diferencias entre ambos libros, se indagará la relación entre biografía y autobiografía y las formas de conversación que Calveyra entabla con las figuras biografiadas: a partir del pasaje de la correspondencia epistolar al “libro-ágora” en Si la Argentina fuera una novela; y a partir de la elaboración de una biografía artesanal en Allá en lo verde Hudson en el que la relectura, la copia, el montaje y la glosa habilitan el desprendimiento de su propios recuerdos.
Matrimonio y escritura en colaboración. El caso de Emma de la Barra y Julio Llanos
Authors: Boiola Karina
Published: June 2023

La escritora argentina Emma de la Barra (1861-1947) es a menudo recordada por un hito que marcó su carrera literaria y las lecturas críticas que se hicieron de ella: la publicación de su primera novela, Stella, en 1905. Esa obra suele evocarse como el primer best seller de la literatura argentina y, debido al éxito comercial que conoció en su tiempo, la atención que se le da a ese libro suele empañar su trayectoria posterior. En este artículo reflexionaré sobre cómo la reconstrucción de la trayectoria vital de esta escritora permite realizar un acercamiento biográfico a su obra que la ilumina desde otra perspectiva. Específicamente, me detendré en el vínculo afectivo y profesional que De la Barra mantuvo con el escritor, periodista y político Julio Llanos, su segundo marido. Al respecto, consideraré la cuestión de lo matrimonial en Stella y en otros textos que la autora publicó en la prensa periódica, para así indagar en las diversas formas de la colaboración que llevó a cabo este matrimonio de escritores.

Authors: Medeiros Luana Dantas , Ferreira Silvio Romero de Melo , Bello Maria Isabela Marques da Cunha Vieira
Published: June 2023

Os solos expansivos sofrem variações volumétricas em decorrência da variação da umidade, e por esse motivo, o seu comportamento varia ao longo do ano em função dos condicionantes climatológicos, havendo expansão e retração, podendo provocar danos nas construções, havendo assim a necessidade de realizar a sua estabilização. Existem vários métodos para realizar a estabilização dos solos expansivos. A Estabilização química dos solos expansivos é um dos métodos de tratamento utilizados para melhorar as propriedades de engenharia tornando o solo adequado para o uso e ocupação. O objetivo do artigo é fornecer uma revisão da literatura abrangente atual de matérias publicadas nos últimos 70 anos sobre o tema. Foram consultados portais de publicações científicas, periódicos, anais de congressos, biblioteca virtual das associações científicas e Biblioteca Digital Brasileira de Teses e Dissertações com busca das palavras chaves solos expansivos e estabilização química. Foram encontradas 78 publicações, destas 44% foram publicadas na década de 2010, os materiais mais utilizados para a formação dos compósitos são Cal, Cinzas, Cimento e derivados de Sódio. Os compósitos mais utilizados foram com cal hidratada (57%) e com cinzas (32%). A formação dos compósitos com dois ou três materiais reduz a expansividade, a tensão de expansão e a propagação e formação de fissuras nos solos expansivos.

La sirena
Authors: Ito Sugiyama Gloria
Published: June 2023

La sirena ha ejercido una atracción irresistible y está presente en el imaginario humano de las más diversas culturas –incluida la del Anáhuac– desde tiempos inmemoriales. El termino de sirena (en griego antiguo, Seirến, ‘encadenado’, ‘cautivo’), y por eso quizá, los griegos se sintieran atados o dominados de alguna forma por esta figura. Se relaciona también, quizá, con el sanscrito: Kimera, ‘quimera’, ya que esta quiere decir sueño o ilusión, producto de la imaginación que el ser humano persigue. Es un ser erótico por excelencia, que produce en quien la mira deseos incontrolados, de ahí su misterio. Posee poderes ocultos, es decir, representa la fantasía del subconsciente, la libertad, pero también la parte femenina del ser humano, se dice. Por otro lado, las sirenas son el reflejo de los miedos a la sexualidad. Por ello, los psicólogos hablan de que la sirena posee un significado más profundo.1 El pez representa el útero y la sirena, como ser mitad pez, tiene que ver con ello.
Socially responsible activities and the economic performance of family businesses
Authors: Srbová Pavla , Režňáková Mária , Tomášková Andrea
Published: June 2023

Promoting the idea of socially responsible business is an undeniably important topic that resonates in both theory and practice. Its influence on business performance has been theoretically substantiated and has been confirmed in many empirical studies, though this has been based on research conducted in large companies. It is only recently that studies connecting the principles of CSR and the business activities of SMEs or family businesses that make up a decisive proportion of SMEs have appeared. This article is devoted to research into the implementation of the principles of CSR in family businesses and their economic performance. The research was conducted on the basis of data obtained both from a questionnaire survey among owners of family businesses and from accounting data. The attitudes of owners of family businesses towards activities typical of CSR were proven to be reflected in the economic results of the companies in a sample of Czech family MSMEs. Our research proved that family businesses that support work-life balance and good relations with employees achieve better performance, namely higher profitability and lower indebtedness. These results confirm the positive impact of CSR principles on long-term sustainability of family businesses and their importance to the country’s overall economy.
Numerical Compliance with EU Fiscal Rules: Facts and Figures from a New Database
Authors: Larch Martin , Malzubris Janis , Santacroce Stefano
Published: June 2023

EU fiscal rules are meant to keep public finances on a sustainable path. This paper presents a new database that tracks numerical compliance with the four main rules of the Stability and Growth Pact starting in 1998. Our assessment of numerical compliance abstracts from the many exceptions and elements of discretion allowed by the letter and the spirit of EU law. It focuses on the main course of action implied by the rules. Overall, our database points to a very mixed compliance record. On average – across countries, years and rules – budgetary policies of the EU member states are compliant in just over half of the cases with stark and persistent differences across countries. We also detect a distinct cyclical pattern of compliance, which sends false signals of safety in good times.
What Can Ukraine Learn from Aufbau Ost?
Authors: Blum Ulrich
Published: June 2023

This article uses Aufbau Ost (or reconstruction of the East) of the new German states as a structural model to estimate the possible costs of an Aufbau Ost 2.0 of Ukraine while taking institutional differences into account. Based on three approaches, the model is validated for the new German states – namely capital coefficients, actual investment flows and actual public transfers – and applied to Ukraine. Key indicators for Germany from 2021 are used as a basis. The economic goal for Ukraine set in this article is to reach Poland’s present level of prosperity in 15 years, which implies a growth rate of 9% per year. This will require a total of US $8.5 trillion over 15 years, which can, however, be financed to a considerable extent by endogenous, investment-driven economic growth if the institutional framework conditions are designed in a market-economy way, especially the taxation system. Transfers and capital imports must close a current account deficit of about US $200 billion per year.
Upturn Over – Interest Rates Weigh Heavily on Housing Construction
Authors: Just Tobias
Published: June 2023

In 2021, 293,000 dwellings were completed in Germany. This is at least 130,000 more than were completed at the low point in 2010, but less than the government had planned in order to limit the housing shortage. It is very likely, that residential construction is going to decline following the strong increase in interest rates and already falling residential prices. This decline in residential construction can only be expected in the short term; in the medium term there are good reasons to believe that Germany has not finished building. It is therefore important to ensure that the elasticity of construction supply is not reduced during this adjustment phase.
Beschäftigung in der Autoindustrie wandelt sich
Authors: Jost Oskar , Nivorozhkin Anton
Published: June 2023

The long-term changes in the aggregate tasks (activities) of employees in the German automotive industry are analysed. The central question is whether the observed changes in activities occur within occupations or are driven by the reallocation of employees between occupations. International studies show that most of the aggregate changes occur within occupations. Our findings confirm these results for Germany. They also show that many occupations have the capacity to adapt and that the fear of joblessness due to technological change seems disproportionate.
Hyperinflation, kollektives Gedächtnis und Zentralbankunabhängigkeit
Authors: Neyer Ulrike , Stempel Daniel
Published: June 2023

The German hyperinflation in 1923 was caused by monetary financing of the highly deficient German state budget by a dependent central bank. The social and economic consequences of the hyperinflation were disastrous. Combined with an instable political atmosphere, paving the way for the rise of the Nazis, the hyperinflation is deeply etched in the German collective memory. It is this collective memory that shapes the current institutional framework of the ECB. While risk aversion and institutional imprint of the ECB’S policy makers differ, the ECB’s institutional framework ensures that current inflation will not evolve into a hyperinflation.
Einspruch gegen Übertreibungen
Authors: Hüther Michael
Published: June 2023

The monetary policy of the European Central Bank has raised questions in the recent past because of the expansive course it has maintained for too long. The policies of the ECB in recent months and announcements about the next steps also raise questions. For years, the doves in the Eurosystem had the power of interpretation and decision-making, but this now seems to lie with the hawks. After the expansive exaggerations, a restrictive phase now threatens. Such debates are reminiscent of a comparable situation 30 years ago, when the German National Bank, after reunification, embarked on a restrictive course with the same force, which irritated even committed economists, stated Olaf Sievert, longstanding chairman of the Council of Economic Experts, in 1992 in Wirtschaftsdienst.
Neue Klimaschutzregeln für den europäischen Luftverkehr – Chancen und Risiken
Authors: Scheelhaase Janina , Grimme Wolfgang , Maertens Sven
Published: June 2023

In December 2022, the EU Commission, the EU Parliament and the EU Council agreed on new climate protection policy measures for European air transport within the framework of the so-called trialogue. The trilogue decision means that European aviation will make a greater contribution to climate protection in the future, as the regulations of the EU emissions trading system will be tightened and incentives for the increasing use of sustainable aviation fuels (SAF) will be introduced at the same time. Whether further measures proposed as part of the Fit for 55 package, such as a European kerosene tax, will be introduced in the future is currently open. This paper provides an overview of the new climate protection regulations that will affect European aviation in the future and the opportunities and risks that will arise from an environmental and economic perspective.
China als Sanktionsmacht: eine Abwägung
Authors: Klein Martin , Goux Maximilien
Published: June 2023

The EU’s search for a new China strategy is driven by the fear of economic dependence on China. There are also concerns about reprisals, particularly in the form of economic sanctions. In official statements, China rejects the use of sanctions and historical data show that it has used sanctions very rarely compared to the USA. On closer inspection, however, it becomes apparent that China does leverage its growing economic power to put pressure on other countries, albeit not in the form of officially declared sanctions. Against the background of empirical studies on the effectiveness of economic sanctions, we discuss the prospects of success of this policy. We show that the vulnerability of Western European countries has increased during the past few decades.
Die ökonomischen Effekte von Sanktionen – Schlagkraft, Zielerreichung, Nebeneffekte
Authors: Yalçin Erdal
Published: June 2023

Sanctions represent a prominent coercive tool that has been utilised extensively in addressing political tensions between nations. These measures are imposed both unilaterally and in alliances of states, and have become increasingly prevalent since the Second World War. In the previous century, particularly before the WWII, trade restrictions and comprehensive economic blockades were the dominant tools to sanction. In contrast, in today’s more interconnected and globalised world, sanctions take on a variety of forms, such as international financial restrictions, travel bans, trade restrictions on specific goods, cancellation of military aid, and targeted measures like flight bans and port closures. The increasing demand for and use of international sanctions raises a fundamental question: Do sanctions lead to political success?
Getreidehandel und Exportbeschränkungen während des Ukrainekrieges
Authors: Götz Linde , Svanidze Miranda
Published: June 2023

Supply chain disruptions related to the Ukraine war have led to a decline in wheat exports from Russia and Ukraine to African countries, which has been largely offset by an increase in wheat exports from other countries. However, fears that disruptions in the grain supply chain will be exacerbated by Russia’s use of grain exports as a weapon and the expansion of economic and financial sanctions by Western countries, as well as the threat of the termination of the Black Sea Grain Initiative, have greatly increased risks in the global grain supply chain. Food security in African countries has therefore been mainly negatively affected by rising food prices, which have limited access to food and thus food security.
Und täglich grüßt das Murmeltier: Die frühe Bildung muss endlich stärker in den Fokus rücken!
Authors: Katharina Spieß C.
Published: June 2023

Given the high benefits of early education, it is particularly noteworthy that new studies of child development during and shortly after the coronavirus pandemic show negative effects on children. This is true for cognitive and non-cognitive skills as well as mental health. Children from low SES families are particularly affected. Although there are fewer studies for preschool children, the few studies that do exist show similar effects; in particular, the closure of daycare centers had a negative impact on children. Last but not least, parental well-being was affected during the pandemic, which will further impact children’s development. The article briefly discusses policy responses in light of these findings. Overall, it argues that education policy should place a much greater emphasis on early education and be more targeted.
Können höhere Löhne zur Überwindung des Fachkräftemangels beitragen?
Authors: Fuest Clemens , Jäger Simon
Published: June 2023

Germany faces an intense debate around labor and skills shortages. The authors argue that increased competition in the labor market and consequently higher wages and better working conditions are a crucial factor to address labor scarcity. This does not mean that other measures to combat labor scarcity, such as reforms to the immigration system, provision of childcare, or tax disincentives are redundant. However, as the demographic transition will dramatically reduce labor supply, increased competition for labor is important to allocate a scarce factor more efficiently.
Strategische Handelspolitik 2.0
Authors: Petersen Thieß
Published: June 2023

The theory of strategic trade policy came into being in the early 1980s. It addressed the question of how a country can increase its own economic welfare through state intervention in the case of oligopolistic world markets. Today, there are many reasons that justify government intervention in foreign trade: Cluster risks in importing raw materials and intermediate inputs, different responses to the negative externalities of greenhouse gas emissions, monopolies in the digital economy, and the growing importance of geopolitical considerations. These developments are likely to lead to a renaissance of strategic trade policy interventions, i.e. subsidies, investment controls and trade restrictions, to name only the most important ones.
Der globale Westen zwischen Schulden, Inflation und geopolitischen Krisen
Authors: Siddiqui Sikandar
Published: June 2023

At a time in which global challenges such as anthropogenic climate change would actually require cross-border coordinated policy action, the selfish pursuit of national interest frequently gains the upper hand in the practice of international economic policy. At the same time, the economic basis of the geopolitical hegemony of the global West is at risk of being undermined due to soaring rates of inflation and an increasing debt burden. If those responsible in business and politics fail to demonstrate, in a credible manner, that they are aware of the existence and scope of the resulting dilemmas, they could expose the internal stability of western democracies to a substantial threat.

Higher-order thinking skills (HOTS) are one of the skills that must be possessed by students in facing the demands of the 21st century. However, Indonesian students' HOTS currently tends to be low. The purpose of this study was to determine the effect of the PBL using STEM approach on students’ HOTS and learning activities. The sample of this study was 48 Junior High students who separated in two clases (experiment and control group). All the students were of 8th grade in SMPN 2 Ajung with a non-equivalent control group design. HOTS data was obtained by giving a pretest and posttest with 10 multiple choice questions. Furthermore, the learning activities was observed via activies observation protocol during the learning process. The application of the PBL using STEM approach was quite effective in the experimental class with a posttest average of 85. This was confirmed by the paired sample test of 0.001 0.05 which could be concluded that the PBL uisng STEM approach had a significant effect on HOTS and learning activities. This finding is an alternative integrative model innovation between PBL and STEM based on students' skill levels

Manda yetiştiriciliğinin avantajları ve mandadan elde edilen ürünlerin insan sağlığındaki üstünlüklerine rağmen, dünyada manda popülasyonunun azalan bir trendle düşük olduğu ve nesli tehlikede olan türler arasında olduğu belirtilmektedir. Dünyada manda yetiştiriciliği yapılan ülkeler arasında manda sayısında en hızlı azalışın gerçekleştiği ülke konumunda olan Türkiye’de, Samsun ili manda popülasyonunda geçmişten günümüze birinci sırada yer almaktadır. Bu çalışmanın amacı Türkiye ve Samsun ilinde 2023-2030 yılları arasında manda popülasyonunun Çift Üstel Düzleştirme ve Holt-Winters yöntemleri ile geleceğe yönelik tahminlerini gerçekleştirmektir. Çalışmada Türkiye manda popülasyon serisi için 1929-2022 yılları arası, Samsun ili manda popülasyon serisi için ise 1991-2022 yılları arası verileri kullanılmıştır. Araştırmada serilerin durağan olmadığı belirlenmiş olup, birinci farkı alındıktan sonra seriler durağanlaştırılmıştır. Manda popülasyon tahmini için Holt-Winters modelinin veri setine en uygun model olduğuna karar verilmiştir. Bu modele göre 2030 yılında 2022 yılına göre Türkiye manda popülasyonunun %7,29 oranında artış yaşanacağı, Samsun ili manda popülasyonunun ise gelecek sekiz yıl içinde stabil kalacağı belirlenmiştir. Çalışmada, yakın gelecekte Türkiye'de manda popülasyonunun yok olma tehlikesi ile karşı karşıya kalacağı belirlenmiştir. Türkiye’de manda varlığının sürdürülebilirliği için hükümet tarafından uzun vadeli ve etkili politika araçları uygulamaya konularak verilen desteklemeler artırılmalı ve tüketicilerin de manda sütü ve etinin faydaları hakkında bilinçlendirilmesi sağlanarak talep artışı sağlanmalıdır.

Atypical aspects of social stratification and mobility
Authors: Samsitdinov Ilnur Zakievich , Girfanova Irina Naskhetdinovna
Published: June 2023

The authors attempts to highlight certain aspects of social relations and social movements that go beyond the traditional typology of social stratification and mobility. It is emphasized that the general vector of modernity, namely the information and digitalization in many areas significantly complements and changes the understanding of mobility. Separately, the social group of "remote workers" is analyzed, the number of which has been growing noticeably in recent years in connection with the informatization of society, as well as in connection with the geopolitical situation, the situation of "uncertainty". Structural-functional, axiological, activity-based approaches were chosen as the methodological basis of the study, the comparative method and the method of scientific analysis were used. The novelty of the research lies in the fact that the article identifies three social groups — "remoters", "organizers", "fallacians", attention to which in classical literature, in our opinion, was not paid enough. In conditions of uncertainty, individuals who are able to design new forms of sociality, which have significant advantages over traditional projects, gain a noticeable advantage. The main conclusion is that social mobility acquires new indicators and is often not associated with the real movements of the subject in space and time. New research and analysis of this phenomenon are required, taking into account the conditions of rapid informatization and transformation of modern society.
