Rechter Terror in Hessen
Authors: Schmidt Sascha , Weyrauch Yvonne
Published: April 2023

2019 und 2020 forderte der rechte Terror in Hessen elf Todesopfer. Dabei gilt das Bundesland mit vergleichsweise gering ausgeprägten extrem rechten Strukturen und einer relativ niedrigen Zahl an Gewalttaten nicht als rechte Hochburg. Wie passt das zusammen?
Um Antworten zu finden haben die Autor*innen die Geschichte rechten Terrors in Hessen nach 1945 aufgearbeitet. Dabei werden Gewalttaten und die dahinterliegenden Strukturen rekonstruiert, zeitgeschichtlich eingeordnet und in ihren Entwicklungen analysiert. Die faktenreiche Arbeit liefert erstmals eine umfassende Darstellung rechten Terrors und kommt zu dem Ergebnis, dass sich dieser wie ein roter Faden durch die Geschichte Hessens zieht.
Das Rentensystem verstehen
Authors: Köhler Tim
Published: April 2023

Die staatliche Alterssicherung steht vor großen Herausforderungen. In den nächsten Jahren werden die geburtenstarken Jahrgänge ins Rentenalter eintreten. Dies wird die Kosten der Alterssicherung rapide ansteigen lassen. Zugleich werden zunehmend Jahrgänge ins Rentenalter kommen, die in ihren Biografien Phasen von Niedrigverdienst und
Langzeitarbeitslosigkeit aufweisen. Das Thema Altersarmut wird vor diesem Hintergrund an Bedeutung zunehmen. Zugleich wird das Anfang der 2000er Jahre von der rotgrünen Regierung durchgesetzte neue "Drei-Säulen-Paradigma" in der Alterssicherung mehr und mehr unter Legitimationsdruck geraten, weil sich seine Ausgangslage
verändert hat. Das Zinsniveau ist seit Jahren niedrig und die private Vorsorge hat insgesamt stark an Attraktivität eingebüßt.
Dieses Buch bietet eine systematische Einführung in Grundfragen und Grundbegriffe der Alterssicherung. Es macht die überaus komplexe Thematik durchschaubar und kann dadurch zur Versachlichung der sozialstaatlichen Debatte in diesem Bereich beitragen. Für die 3. Auflage wurde es aktualisiert.
Mündigkeit in der historischen Bildung
Authors: McLean Philipp
Published: April 2023

Warum sollen Schüler*innen Geschichte lernen? Im Kontext dieser Frage zeichnet der Autor nach, welche Zielvorstellungen von verschiedenen Akteur*innen in der historischen Bildung als legitim gesehen werden. Hierbei rückt vor allem der Erwerb von Mündigkeit durch historische Bildung als zentrales und gemeinsames Ziel in den Vordergrund. Außerdem entwickelt Philipp McLean auf Basis der Kritischen Theorie den Vorschlag eines emanzipativen Mündigkeitsverständnisses, das auch über den Geschichtsunterricht hinaus Schüler*innen Möglichkeiten für ihre Selbstbestimmung im Bildungsprozess aufzeigen soll.
Autorität in der Schule auf den Punkt gebracht
Authors: Geisler Wolfgang
Published: April 2023

Im Berufsleben von Lehrerinnen und Lehrern vergeht kaum ein Tag, an dem sie nicht irgendwann plötzlich und oft ganz unerwartet mit dem Problem ihrer Autorität konfrontiert werden. Besser, man ist darauf vorbereitet. Autorität ist eine soziale Kompetenz, allerdings unter Umständen auch eine nur flüchtige Erscheinung. Man braucht sie, aber sie kann einem auch entgleiten. Realitätsnah beschrieben bringt dieses Buch Sinn und Formen der Autorität auf den Punkt, beschäftigt sich mit der autoritären Versuchung im Unterrichtsalltag sowie mit den Möglichkeiten, pädagogische Autorität zu erwerben, zu besitzen und zu erhalten und bietet so unterstützende Impulse für die Praxis.

Authors: Polak Regina
Published: April 2023

In diesem Band werden anlässlich des Gedenkens an die Gesera 1421 die inter- und transdisziplinären Analysen des aktuellen Antisemitismus dokumentiert sowie die Handlungsperspektiven zu seiner Bekämpfung aufgezeigt. Die Befunde renommierter Expert:innen belegen die historische Kontinuität, die kirchliche Verantwortung sowie die
demokratiepolitische Brisanz des Antisemitismus, der die jüdische Bevölkerung und die soziale Kohäsion in Österreich bedroht.
Die multiperspektivische Annäherung, die Verschränkung zwischen Theorie und Praxis wie auch der intergenerationale Diskurs geben Antworten auf die Frage, warum man sich fast 80 Jahre nach dem Ende der Shoah nach wie vor mit Antisemitismus auseinandersetzen muss.

Yaşlı bakımı, geleneksel ve profesyonel bakım kapsamında tüm bireyleri ilgilendiren önemli bir süreçtir. Son zamanlarda yapılan araştırmalar sonucunda, ülkemizin demografik yapısının değiştiği ve yaşlı nüfusunun beklenmedik bir düzeyde artış gösterdiği saptanmıştır. Dünya Sağlık Örgütü’nün yürütmüş olduğu çalışmalar çerçevesinde, ülkemizde ilerleyen yıllarda yaşlı nüfusunun artış göstermeye devam edeceğinin tahmin edilmesi yaşlı bakımını daha da ön plana çıkartmıştır. Nüfusun yaşlanmasına bağlı olarak yaşlı bakımına ihtiyaç duyacak kişi sayısının da artış göstermesi beklenmektedir. Bu durum bakım verici rolünün üstlenmesinde formal ve informal bakımda farklılıklar yaşanmasına sebep olmaktadır. Yaşlı bakımına yönelik hizmetler; evde bakım, kurumsal bakım ve son zamanlarda ön plana çıkan yerinde yaşlanma şeklinde gerçekleşmektedir. Bu hizmetlerin ortak amacı, bakım hizmeti sağlanırken bakıma ihtiyacı olan bireylerin insan onuruna yakışır şekilde hayatını sürdürebilmesidir. Ulusal ve uluslararası literatür incelendiğinde, yaşlı bakım modellerinin bütüncül olarak ortak ve karşılaştırmalı özelliklerini ortaya koyan çalışmaya rastlanmamıştır. Bu çalışma yaşlı bakım modellerinden olan evde bakım, kurum bakımı ve yerinde yaşlanma olgularının avantaj-dezavantaj ve politikalar ekseninde karşılaştırılması amacıyla hazırlanmıştır.

Investigating the Turn of the Month effect: Evidence from International Financial Markets
Authors: Enow Samuel Tabot
Published: April 2023

Market anomalies are predictable patterns in financial markets that contradicts the efficient market hypothesis and the random walk theory. Several anomalies have been documented ever since the emergence of behavioural finance in the early 90s. The Turn of the Month anomaly is a well-known pattern that has resonates a lot of controversy in finance. Advocates of the Turn of the Month effect contends that stock market returns tend to be higher at the last few trading days of the month which spills over to the first two to three trading days of the following month. The aim of this study was to empirically investigate the Turn of the month effect before and during the Covid-19 pandemic so as to validate or repudiate the concept. This study used a sample period from June 30, 2017 to June 30, 2019 and January 1, 2020 to December 31, 2021 in the JSE, Nasdaq, CAC 40, DAX, BIST 100 and Nikkei 225. The findings revealed no evidence to support the TOM effect although some of the financial markets experienced higher returns at the end of the month such as the JSE and Nasdaq. Therefore, the Turn of the Month effect cannot be a trading strategy to realised abnormal returns than the market.

Authors: Hafid Hapsah , Mardan Mardan , Damis Rahmi , Asriadi Asriadi
Published: April 2023

Interaksi social berarti tindakan(action) yang berbalasan antar individu atau antar kelompok. Tindakan saling memengaruhi ini seringkali dinyatakan dalam bentuk symbol-simbol atau konsep-konsep. Secara sederhana komunikasi dapat dikatakan sebagai proses interaksi maupun proses perubahan social yang lebih baik, dan pada prinsipnya melalui kegiatan komunikasi yang kita bangun diharapkan mampu memunculkan proses interaksi maupun perubahan social bagi masyarakat baik muslim dan non muslim.Islam adalah agama universal yang ajarannya ditujukan kepada umat manusia secara keseluruhan. Inti ajarannya selain memerintahkan kepada penegakan keadilan dan mengeliminasi kedzaliman, juga meletakkan pilar-pilar perdamaian yang diiringi dengan himbauan kepada umat manusia agar hidup dalam suasana persaudaraan dan toleransi tanpa memandang perbedaan ras. Interaksi sosial dibangun atas dasar nilai persamaan toleransi, keadilan, kemerdekaan dan persaudaraan. Nilai-nilai al-Ikhwah alInsaniyah tersebut idealnya untuk menjadi landasan utama membangun interaksi sosial dalam kemajemukan demi mewujudkan perdamaian abadi di muka bumi secara seluruhnya dan di Indonesia khususnya.

Interaksi sosial muslim kepada nonmuslim adalah sikap saling menghargai dan menghormati dalam urusan sosial kemasyarakatan yang didasarkan kepada nilai-nilai luhur yang bersumber dari ajaran alQuran dan al-hadits (agama Islam). Nilai-nilai tersebut adalah saling mengenal (memahami), membangun budaya kompromi, berbuat baik, berperilaku adil dan saling membantu, regulasi tertulis (dokumen) yang menunjukkan komitmen dan konsisten serta persamaan dalam arti yang seadil-adilnya. Nilai-nilai tersebut direkomendasikan untuk menjadi landasan dalam menangani masalah multikultur, multiagama, multibahasa, multibangsa atau kehidupan yang plural secara umum.

Published: April 2023

Tulisan ini berusaha mengkaji tentang teori komunikasi dalam perspektif komunikasi Islam, penelitian ini merupakan penelitian kualitatif dengan penelusuran kepustakaan, data diperoleh dengan cara observasi dan dokumentasi. Peneliti dalam penelitian ini juga melakukan reduksi data, display data, dan ferivikasi data, selanjutnya untuk keabsahan data menggunakan perpanjangan penelitian. Temuan analisis mengungkapkan bahwa teori komunikasi merupakan kebutuhan komunikasi karena teori komunikasi adalah pedoman, acuan, payung dan referensi dari aktivitas komunikasi, namun pada aktivitas komunikasi banyak ditemukan tentang teori-teori komunikasi yang lebih menekankan pada kepentingan individu dibandingkan dengan kepentingan  bersama. Sebagian besar teori barat terlalu menekankan pada visi individualisme, cenderung aktif mencapai tujuan personalnya, namun komunikasi dalam perspektif komunikasi Islam ditemukan pentingnya mewujudkan kebersamaan dan adanya etika dalam komunikasi. Komunikasi dalam perspektif Islam mengharuskan pelibatan emosi yakni komunikasi dengan ekspresi sebagai bentuk aspek nonverbal (visual) yang terdapat dalam Q.S.Al-Rahman ayat 1-4, selanjutnya dalam aspek verbal dan vocal diatur dalam beberapa ayat dan surat yaitu qaulan sadidan (perkataan yang tegas dan benar), qaulan balighan (perkataan yang membekas), qaulan ma’rufan (perkataan yang baik, qaulan kariman (perkataan yang mulia), qaulan layyinan (perkataan yang lemah lembut), qaulan maysuran (perkataan yang pantas), qaulan tsaqila (perkataan yang berat), qaulan adziman (perkataan yang besar), ahsanu qaulan (perkataan yang paling baik)

Published: April 2023

EBA guidelines on Interest Rate Risk in the Banking Book (IRRBB) are designed to help EU banks effectively manage their interest rate risk and maintain a stable earnings stream. EBA also requires the credit spread risk from the banking book (CSRBB). Banks can effectively manage their exposure to interest rates and spread risks by implementing a comprehensive IRRBB and CSRBB management framework that includes: regular stress testing, sensitivity analysis, effective hedging strategies, and appropriate governance and risk management structures. Under those frameworks, banks must regularly monitor and report interest rates and credit spread risk metrics.

To ensure the stable operation of the technological equipment of an infocommunication company, it is proposed to consider a strategy for managing the costs of maintaining equipment in case of probable failures. An analysis was carried out under the conditions of uncertainty of the appearance of failures on the example of the functioning of the network of one of the leading infocommunication companies in Kazakhstan. Based on this, an optimization-computational model was created, the input parameters of which are the failure probabilities of the basic equipment of an infocommunication company, and the output parameters are the value of the optimal equipment replacement time and the objective function. The choice of the objective function is reduced to minimizing the time for attracting and storing equipment components. The problem of failure management is formulated as a continuous stochastic optimization problem. This article is devoted to the development of a unique mathematical model that solves the problem of failure management. The developed software implementation of the task of managing inventory of equipment in case of random failure shows the calculations of the proposed mathematical model, minimizes the costs of maintaining equipment and most corresponds to the conditions for the functioning of an infocommunication company, taking into account modern features of economic fluctuations in the financial market and the rapid development of IT technologies.

In this paper, we consider a partial differential equation with involutively transformed arguments in a rectangular domain. The considered equation is a non-local analog of the second-order hyperbolic type equation. This equation is subject to initial-boundary conditions, and the order of the boundary operators exceeds the order of the equation. Questions of correctness of the considered problem are investigated. To solve the problem, the Fourier method is used, i.e. separation of variables method. The properties of eigenfunctions and eigenvalues of the corresponding spectral problem are studied. For the main problem under consideration, theorems on the uniqueness and existence of a solution are proved. When proving the theorem on the uniqueness of the solution, the problem under study is reduced to two auxiliary, homogeneous initial-boundary value problems for a classical equation of hyperbolic type. The resulting equations depend on the coefficients of the main equation and certain conditions are imposed on them. Further, using the completeness of the eigenfunctions of the auxiliary spectral problem, the solution of the main problem is sought in the form of a series in this system. For the unknown coefficients of the series, a system of ordinary differential equations with high-order boundary conditions is obtained. Solving these problems, we find an explicit form of the solution of the main problem under study.

The concern of this research was to review the different methodology on microfluidic experiments conducted to study chemical enhanced oil recovery methods on micromodel chips. In general, there are several ways to study EOR methods such core flooding and microfluidics. The disadvantage of first method is that the flow processes inside the core sample cannot be imagined. Hence, the second method helps us to fully visualize how fluid flow behaviour occurs though the porous medium of the rocks. The various chemical EOR processes such as surfactant flooding, polymer flooding and ASP flooding were studied on microfluidic chips. These chemicals were injected into micromodels to drive out crude oil. It helps to understand the interactions between crude oil and chemicals, the advancement of front developed between displacing and displaced fluids and the viscous fingering effect. Visual studies enabled us to understand the effectiveness of polymer, surfactant and alkaline separately and as combined. The different experimental methodologies to study the EOR methods are reviewed. Mainly experiments divided into two main groups: methods of geological characterisations influence to fluid transport while others study oil displacement at different condition, such high temperature, high pressure, low or high salinity, highly viscous oil. We reviewed methodologies applied to study an oil displacement by polymer, surfactant-polymer (SP) and alkaline surfactant polymer (ASP) solutions, their interactions and transport in porous media. Based on reviewed article the experimental procedure was developed. Analyses of published materials have helped to design and direct the methodology of research.

The article describes the use of a variational method involving the finite element method to estimate the law of temperature distribution in a body in the form of a rectangular parallelepiped. The case is considered when a certain temperature is maintained on one of the faces of a rectangular parallelepiped, and heat exchange with the environment occurs on the opposite side. In accordance with the proposed approach, an approximating function in the form of a polynomial of the third degree is proposed. To determine the law of temperature distribution in a solid in the form of a rectangular parallelepiped, a functional is compiled, which consists of terms that take into account temperature, heat exchange with the environment, isolation of the faces of a rectangular parallelepiped, as well as natural boundary conditions. Minimizing this functional, the temperature values at these nodes are determined by the nodal points of a rectangular parallelepiped. Further, substituting these values into the approximating function, we obtain the temperature distribution law. At the same time, variants are investigated when the remaining faces of a rectangular parallelepiped are thermally insulated or vice versa. The temperature distribution law is estimated for different amounts of partitioning of the sides of a rectangular parallelepiped. In addition, a comparison of the temperature distribution law for a rectangular parallelepiped and a rod close in size, other things being equal, was made. Their minor differences are shown.

After the use of the Internet and the transmission of files between users expanded, information security became one of the important priorities for securing information by different means and methods. The information encryption comes at the forefront of the techniques used in information security. Encryption has been known since ancient ages. So, traditional methods appeared that quickly and greatly developed. They are still used in many scientific studies and developmental research with the aim of developing new methods for encryption of substitutions and increasing its ability to confront various attacks. The traditional methods were subjected to several attacks that they prompted researchers to develop them and overcome their weaknesses in front of those attacks. Some combinations of these methods are used to design new encryption methods based on overlapping ideas of traditional encryption. This paper sought to use a set of traditional encryption methods in designing a new system. In which, these methods are mixed with modern ideas that help increase the strength of encryption and its ability to face potential attacks. Caesar, Vigenère, Rail Fence, and transpose ciphers, with the idea of cipher cycles and segments and division into two parts in block ciphers. The proposed system relied on the chaotic function Tent map for its random properties in generating a string of keys consisting of 112 random characters in length using Python 3.11 programming language. The text was cut into Blocks of 108 characters. Each Block was divided into two parts. A part of the key was added to each section. A rial fence method was applied. Then Vigenère method with the key is applied. The proposed system processed the original text within the framework of the encryption cycles with the use of substitution in the order of the columns, shifting to the right, and the replacement of the sequence of the elements of each side according to the order of the elements of the other side. After the end of the encrypting cycles, the cipher block is added to the final ciphertext. The operations were repeated for the next block until the last block is finished. For the purpose of decrypting, the previous operations are repeated in reverse order to obtain the original text, by decrypting blocks of the cipher text. The proposed system achieved extreme accuracy in extracting the original text. The system was evaluated by measuring the time and throughput of the encryption and decryption. The encryption and decryption times were short for short texts, which increased with the increase in the length of the text, with a relatively stable encryption and decryption throughput. The system achieved acceptable memory consumption in short texts but increased by the length of the text size. The achieved Avalanche test was less than (50%).

The world energy demand is continuously increasing. Due to environment issues, global warming, and other issues, there is a need for clean sources of energy, sustainable energy, i.e. renewable energy technologies. Photovoltaic (PV) technology employing solar energy is regarded as rather most promising and efficient technology among all the renewable energy industries. The further improvement in the efficiency and reliability and also reduction in cost are in great demand, for the healthy development of global economy.  Among the third generation solar cells, perovskite cells have attracted a lot of attention due to their high efficiency and low cost construction methods. In this research, low-cost perovskite solar cell (PSC) was prepared, and its photovoltaic performance was investigated. In this project, we tried to get rid of some structures or materials which are harm to the environment. i.e. car batteries. By using lead sheets (from recycled car battery). However, by reusing car batteries we will avoid the disposal of toxic battery materials and provide an alternative, readily-available lead source for fabricating PSC. Perovskite solar cell was prepared by two-steps spin coating solution technique on glass substrates at various thermal annealing deposition  temperature. Then photovoltaic performance of PSC was investigated, together with the stability of PSC, and the effect of annealing temperature of perovskite layer on performance of perovskite solar cell. The efficiency of the cell, subjected to thermal annealing at temperature of 100, for 12 minutes was (14.8%). Then the efficiency of the cell altered to  (12.4%),  after 105 days  ageing at  room temperature.

With the rapid increase of efficiency up to 23.7% during the past few years, hybrid organic-inorganic metal halide perovskite solar cells (PSCs) have become a research “hot spot” for many solar cell researchers. The perovskite materials show various advantages  due to unique characteristics of perovskite materials, such as high photo-to-electric conversion efficiency, direct band gap, high light absorption coefficient, high charge-carrier mobility and long electron-hole electron transport distance. The low-cost fabrication techniques together with the high efficiency makes PSCs comparable with Si-based solar cells. This paper begins with the discussion of crystal structures of perovskite based on recent research findings. The following part of this paper discussion of synthetic process of lead iodide perovskite materials from lead-acid battery and Harvesting material from the anodes and cathodes of car battery; synthesizing PbI2 from the collected materials and compare with pure Lead iodide to know the absolute by XRD peak, depositing lead iodide perovskite nanocrystals. Efficient flexible PSCs are fabricated onto FTO glass  substrate by a two-step coating method under ambient condition. By adjusting the concentration of precursor CH3NH3I (MAI), the morphology and thickness of perovskite layer is effectively tailored, according to SEM analysis and using TiO2 as electron transport layer instead of ZnO and CuI instead of spiro-OMeTAD as hole transport layer.

This study aims to see the effect of temperature and extraction time on moisture content, yield and methoxyl pectin content of coconut coir. This research was conducted with a factorial experiment in a completely randomized design (CRD), which consisted of two treatments, namely extraction temperature and extraction time with three replications. The results of this study indicate that the extraction temperature greatly affects the pectin yield, water content and methoxyl pectin while the extraction time affects the pectin water content. At a temperature of 70OC and an extraction time of 60 minutes, the highest average yield of pectin was obtained, namely 4.31%, while the lowest average yield of pectin was obtained from the treatment of an extraction temperature of 90OC and an extraction time of 90 minutes. The highest average methoxyl content was obtained from a temperature treatment of 70OC and an extraction time of 30 minutes, while the lowest average percentage of methoxyl content was obtained from a temperature treatment of 90OC extraction and an extraction time of 90 minutes, namely 8.03% and 7.61%, respectively. From the results obtained, it was concluded that the pectin obtained belonged to the pectin group with high methoxyl content, namely >7%. The lowest average percentage of pectin content was obtained at 90OC and 90 minutes of extraction time, namely 10.19%, while the highest was obtained from the treatment of 70OC extraction temperature and 30 minutes of extraction time. From the results of the analysis of water content, it was found that the water content of cocopeat pectin obtained in this study fulfilled the requirements for dry pectin moisture content, namely 10-14%.
