The Interpellation of Misogyny By Female Characters
Authors: Septia Larassati Alya , Wahyuni Delvi
Published: June 2022

This thesis is an analysis of Otessa Moshfegh's novel entitled EILEEN (2015). This analysis is related to the concept of Interpellation by Luis Althusser and Misogyny by SheilaJeffrey and it is under the Feminist literary theory which can reveal issues in the novel. This can be seen in two methods: form of misogynistic women and the way misogyny can get interpellated. The issues raised are women who interpellated the ideology of misogyny and they also did it. Self-judgement, self-objectification, and negative attitude toward other women are the dominant forms of mysoginistic behaviour expressed by female characters in this novel.  Family and workplace are the place or the background how this ideology can be interpellated. The analysis shows that misogyny is not only done by men but women also do it. It can be concluded that the ideology formed by these patriarchs is indirectly also supported by women.

Published: June 2022

Cognitive is relating to cognition. It refers to the method by which knowledge is acquired and manipulated. Usually, cognition is mental. The mental processes associated with phenomena such as concentration, logic, thought and evocation. Generally, characterized as reflects the mind. It is not observable directly, but it must be inferred. Malaysian educators trying so hard to make sure all students master or at least having good knowledge in Mathematics. Investigation on cognitive levels towards performance of Mathematics score among secondary school’s students is the main purpose of the study. A secondary data was used for the process of investigation. A total of 118 secondary school’s students in Tapah were involved randomly. The analyses were started using multiple linear regression with the aid of IBM SPSS version 24. Results show that cognitive levels significantly affect the performance of Mathematics score. These cognitive levels include Knowledge (C1), Comprehension (C2), Proficient (C3), Synthesis (C5), and Analysis (C6). Among five levels of cognitive, results show that Comprehension (C2) or in other words understanding of facts and ideas give the highest impact towards the performance of Mathematics score. If the students do not understand well in topics covered from Mathematics, they will not perform well in Mathematics. In this situation, both teachers and students play an important role to make better results in Mathematics.
Governance drivers of rural water sustainability: Collaboration in frontline service delivery
Authors: Thapa Dikshya , Farid Muhammad Noor , Prevost Christophe
Published: June 2022

This paper contributes to a long-standing debate in development practice: under what conditions can externally established participatory groups engage in the collective management of services beyond the life of a project? Using 10 years of panel data on water point functionality from Indonesia’s rural water program, the Program for Community-Based Water Supply and Sanitation, the paper explored the determinants of subnational variation in infrastructure sustainability. It then investigated positive and negative deviance cases to answer why some communities successfully engaged in system management despite being located in difficult conditions as per quantitative findings and vice versa. The findings show that differences in the implementation of community participation, driven by local social relations between frontline service providers, that is, village authorities and water user groups, explain sustainable management. This initial condition of state-society relations influences how the project is initiated, kicking off negative or positive reinforcing pathways, leading to community collective action or exit. The paper concludes that the relationships between frontline government representatives and community actors are important and are an underexamined aspect of the ability of external projects to generate successful community-led management of public goods.
Green infrastructure and planning procedures – experience of creating an unofficial network of green spaces as an NGO
Authors: Spajić Marijo
Published: June 2022

Article focuses on recognizing valuable green spaces and strategic positioning of new green infrastructure elements in space from the perspecitve of a non-governmental organization. It questions the limitations, roles, and possibilities of non-governmental organizations (NGO‘s) in the establishment of publicly accessible and environmentally significant areas in the urban matrix. The article considers personal experiences in the implementation of such projects, their influence on the daily livelihood of citizens and how an NGO can contribute bypassing current absence of legal basis for its implementation. The methods presented in the paper are described as informative guidelines and are not scientifically backed, although they do rely on scientific knowledge of the members of NGO and previously tried methods of earlier finds. This work represents a factual outcome of actions delivered by the NGO ZIPS (Zelene i plave Sesvete) and do not have to be replicative on other showcase examples, considering their legal, cultural, and other backgrounds.
Population analysis of smallmouth silverside, Chirostoma chapalae Jordan & Snyder, 1899 (Atherinopsidae), an endemic fish in Lake Chapala, Mexico
Authors: Gomez-Vanega Hosmer Duvan , Espino-Barr Elaine , López-Uriarte Ernesto
Published: June 2022

A sample was analyzed of 1,129 specimens of Chirostoma chapalae from Lake Chapala, Mexico obtained from catches of local fishers between October 2016 and September 2017. Size frequency, length-weight relationships (LWRs), growth, mortality, exploitation rate, survival rate, and relative condition index were estimated. The LWRs showed negative allometric growth in females (b = 2.735) and isometric growth in males (b = 3.000). The SL∞ was 9.20 cm in females and 8.94 cm in males, and the growth coefficient k ranged from 1.80 year−1 to 1.90 year−1, and the t0 from 0.119 to 0.113. Estimated total mortality (Z = 3.20 year−1), natural mortality (M = 1.56 year−1), and fishing mortality (F = 1.64 year−1) values were higher in females. C. chapalae is at optimum, underexploited levels according to the exploitation rate (E = 0.42 year−1). The SL at first capture (SLpc) was 65.8 mm and the SL at retention (SLpr) of the fishing gear was 62.4 mm. This indicates that more than 50% of the fish caught enter the fishery at a larger size. The condition factor (Kn) showed body robustness in fall and subsequent spawning from spring onwards. Our findings contribute to the future development of fisheries management strategies in the largest lake in Mexico.

Published: June 2022

The objective of the present study was to analyze the morphometric and meristic variations of an estuarine fish, Etroplus suratensis, in five locations along the South Indian coastal region. In total, 651 individuals were collected and 16 morphometric and six meristic counts were taken. The results of univariate (ANOVA) and multivariate (Principal Component Analysis, PCA) analyses showed that the east coast stocks (Machilipatnam, Mudasalodai, Rajakkamangalam) have overlapping morphological characteristics, whereas the west coast stock (Cochin) was distinctly different, but there were no significant differences observed in meristic characters among the five stocks. Therefore, it was presumed that Machilipatnam, Mudasalodai, and Rajakkamangalam were the same stock. The morphometric data discriminated E. suratensis into two stocks, i.e., those of the east and west coasts. However, further molecular-based analysis is very much needed to validate these stocks.

Authors: Özmen Erhan , Kan Ayşe Ülkü
Published: June 2022

With the effect of the COVID-19 virus, which emerged at the end of 2019 and caused a pandemic in the world, education has experienced a significant interruption and the world has embarked on a quest for alternatives for educational practices. Distance education, where the learner and the teacher can perform education by being in different places, has reached the forefront with its applicability to pandemic conditions and has increased its importance. As a result of these developments, the concept of emergency distance education, which is a temporary transfer of face-to-face education to technological environments, has emerged and has been put into practice. Educational institutions, which had to start distance education practices in a very short time, experienced various problems due to student density and limited time. It is considered important in order to reveal the experiences of distance education staff who are directly faced with these problems, to offer solutions to the problems and to be prepared for extraordinary situations that may occur later. The purpose of this study is to identify the problems experienced by the staff of the distance education center (DEC) in the distance education applications carried out during the pandemic and to make suggestions for the solution of these problems. In line with this purpose, focus group interviews were conducted with a total of eight personnel, three of whom were administrative, four of whom were academic and one of whom was technical, working in different positions at the distance education center of a university. The sample was determined in accordance with the convenience sampling. The data obtained in the study using phenomenology, which is one of the qualitative research designs, were analysed by content analysis method. As a result of the study, it was determined that the problems experienced by DEC staff in this process were grouped under four categories as student-centred, instructor-centred, system-centred, and other problems, and solution suggestions were presented within the framework of these problems.

The following study presents an example of Holocaust education for the 21st century by evaluating the “Wannsee-conference” 80 years ago (January 20, 1942) from a religious psychological perspective of 2022. After a general survey concerning Holocaust education in Germany, it focuses on emotional regulation as a coping strategy with emotionally loaded situations, demonstrated by the conference participants but also by the trials 1946 in Nuremberg, and 1961 in Jerusalem (Eichmann). The main purpose of the study is how students 80 years later can draw benefit from evaluating the documents from a religious (psychological) perspective. The educational focus, therefore, is on reconstructing and deconstructing such strategies to develop intrapersonal, interpersonal, intra- and inter-cultural emotional competencies.

Published: June 2022

This paper analyses the transverse deflection in a homogeneous, isotropic, visco-thermoelastic beam when subjected to harmonic load. The ends of the beam are considered at different boundary conditions (both axial ends clamped, both axial ends simply supported and left end clamped and right end free). The deflection has been studied by using the Laplace transform. Numerical computation of analytical expression of deflection obtained after Inverse Laplace transform has been done using MATLAB software. The graphical observations have been discussed under various boundary conditions for different values of time and length. The above work has applications in design of resonators.

Authors: Habib Merouane , Rachid Sahnoun , Ismail Drai
Published: June 2022

In this paper, we focus on the effect of the inner diameter and Reynolds number on the recirculation zone in an annular jet flow with numerical simulation by resolving the Reynolds-averaged Navier-Stokes equations with the first closed model of turbulence k-epsilon. The annular jet plays an essential role in stabilizing the flame in the burner which is used in many industrial applications. The annular jet is characterized by the inner and outer diameter. In this study, three different inner diameters are adopted with constant width of the annular jet. We adopted also three different values of the Reynolds number show the effect of the Reynolds number on the recirculation zone. The simulation is realized by a CFD code which uses the finite element method. The results obtained from this study are in good agreement with the experimental data. Two recirculation zones are shown; a large recirculation zone at the outlet of the flow and a small recirculation zone just near the injection generated by the annular flow and the inner diameter Di; it is observed that the size of the recirculation zone increases when the inner diameter increases and the length of the recirculation zone depends only on the inner diameter. This recirculation zone is also affected by the Reynolds number with a very low variation of the recirculation length.

Authors: Jauhri Shefali , Mishra Upendra
Published: June 2022

An electrically conducted viscous incompressible nanofluid flow caused by the nonlinear stretching surface with stagnation flow has been investigated numerically. The effect of Brownian motion and thermophoresis on the nanofluid is also incorporated. The governing partial differential equations with nonlinear second order boundary conditions are solved by the fourth order Runge-Kutta technique using MATLAB programming. The effect of the radiation parameter (Rd), stretching parameter (n), Brownian motion parameter (Nb), thermophoresis parameter (Nt) on temperature, velocity and mass transfer are shown graphically. The influence of some of these parameters on the local Nusselt number (− θ′(0)) and local Sherwood number (−ϕ′(0)) are shown by the graphs.

Authors: Khrouf F. , Tebassi H. , Yallese M.A. , Chaoui K. , Haddad A.
Published: June 2022

An experimental investigation is carried out to examine the effects of various cutting parameters on the response criteria when turning EN-AW-1350 aluminum alloy under dry cutting conditions. The experiments related to the analysis of the influence of turning parameters on the surface roughness (Ra) and material removal rate (MRR) were carried out according to the Taguchi L27 orthogonal array (313) approach. The analysis of variance (ANOVA) was applied to characterizing the main elements affecting response parameters. Finally, the desirability function (DP) was applied for a bi-objective optimization of the machining parameters with the objective of achieving a better surface finish (Ra) and a higher productivity (MRR). The results showed that the cutting speed is the most dominant factor affecting Ra followed by the feed rate and the depth of cut. Moreover, the Artificial Neural Network (ANN) approach is found to be more reliable and accurate than its Response Surface methodology (RSM) counterpart in terms of predicting and detecting the non-linearity of the surface roughness and material removal rate mathematical models. ANN provided prediction models with a precision benefit of 8.21% more than those determined by RSM. The latter is easier to use, and provides more information than ANN in terms of the impacts and contributions of the model terms.

This work studies the simultaneous effects of helical force, rotation and porosity on the appearance of stationary convection in a binary mixture of a ferrofluid and on the size of convection cells. We have determined the analytical expression of the Rayleigh number of the system as a function of the dimensionless parameters. The effect of each parameter on the system is studied. The consideration of the simultaneous effect of the basic characteristics made it possible to determine the evolution of the convection threshold in the ferrofluid and then the size of convection cells. The analyzes of the various results obtained allowed us to deduce whether the convection sets in quickly or with a delay when the various effects taken into account in the study are considered simultaneously.

Introduction: The subcutaneous implantable cardioverter defibrillator (S-ICD) represents a major advancement in ICD technology. Inappropriate shocks (IAS) occur in more than 3.1% of the population with S-ICD each year and are usually followed by admission to the emergency department (ED). In this setting, the disabling of IAS is mandatory during a pseudo-electrical storm (ES). This report describes the strategies that can be followed in order to temporarily inhibit IAS in critical care settings with the use of magnets.

Case presentation: An S-ICD was implanted more than 6 weeks prior to presentation in a 68-year-old man with hypertrophic cardiomyopathy. In the ED, the patient experienced 3 IAS in the last hour. A Medtronic magnet was applied to stop IAS, as the specific programmer was not available. The maneuver interrupted the IAS. In order to verify the universal magnetic response of the S-ICD, six different magnets and one smartphone with MagSafe technology were tested. All magnet models suspended arrhythmia detection and IAS, while the smartphone did not cause magnet interferences.

Conclusions: This report demonstrates the safety and efficacy of all clinical magnet models in inhibiting IAS. In case of pseudo-ES, any type of magnet allows ED providers to easily and rapidly disable the functionality of the devices when appropriate.
Total Process Error: An Approach for Assessing and Monitoring the Quality of Multisource Processes
Authors: Rocci Fabiana , Varriale Roberta , Luzi Orietta
Published: June 2022

Most National Statistical Institutes are progressively moving from traditional production models to new strategies based on the combined use of different sources of information, which can be both primary and secondary. In this article, we propose a framework for assessing the quality of multisource processes, such as statistical registers.

The final aim is to develop a tool supporting decisions about the process design and its monitoring, and to provide quality measures of the whole production. The starting point is the adaptation of the life-cycle paradigm, that results in a three-phases framework described in recent literature. An evolution of this model is proposed, focusing on the first two phases of the life-cycle, to better represent the source integration/combination phase, that can vary accordingly to the features of different types of processes.

The proposed enhancement would improve the existing quality framework to support the evaluation of different multisource processes. An application of the proposed framework to two Istat (Italian national statistical institute) registers in the economic area taken as case studies is presented. These experiences show the potentials of such tool in supporting National Statistical Institutes in assessing multisource statistical production processes.
Editorial: COVID-19 Pandemics and Politics
Authors: Hintea Calin Emilian , Klun Maja , Nemec Juraj
Published: June 2022

This short editorial proposes a specific topic for comprehensive research in COVID-19 in the CEE area, namely the role of politicians and politics during the pandemic. The text includes three short country case studies (Romania, Slovakia, Slovenia), describing different aspects of the politics/political fighting relationship and the COVID-19 pandemic. The experts’ arguments suggest that the “motto of the day” should be working together and not fighting each other. However, nothing (“almost nothing”) like this is visible in our region – or at lease in our three case studies, the only positive aspect from this point of view is the joint call of all parliamentary group leaders for vaccination in Slovenia. By its content, the editorial calls for comprehensive research on the aims of the current antagonistic situation and possible actions.
Flattening the Curve. . . of Spirographs
Authors: Konkar Ranjit
Published: June 2022

The Spirograph is an old and popular toy that produces aesthetically pleasing and fascinating spiral figures. But are spirals all it can make? In playing with a software implementation of the toy, the author chanced upon a variety of shapes that it can make that are different from its well-known repertoire of spirals, in particular, shapes that have a visible flatness and not the curved spiral geometry that we are accustomed to seeing from the Spirograph. This paper reports on these explorations by the author and his delightful discovery of very elegant and simple geometric relationships between the Spirograph’s structural parameters that enable those patterns.

Foreign direct investment is one of the major factors for the development of national economies with positive implications for the growth of their gross domestic product, technology transfer, as well as increased competitiveness and improved performance of local companies. They generate investment capital, provide new employment, transfer expertise and skills to employees, and increase exports. In the Republic of North Macedonia a number of reform activities have been undertaken relating the protection of property rights, improvement of the efficiency in the functioning of the legislative, judicial and executive branches of government, which result with reduced business risks and motivates companies to make investment decisions. Current paper aimed at outlining the connection between the effectiveness of the judicial system and increasing the number of foreign direct investments in the Republic of North Macedonia.
Digitalität - Zur Philosophie der digitalen Lebenswelt
Authors: Noller Jörg
Published: June 2022

Die Digitalisierung prägt und transformiert unser alltägliches Leben zunehmend; eine digitale Lebenswelt entsteht. Sie ist in ihrer Komplexität nicht mehr rein technik- oder medienphilosophisch zu verstehen, sondern bedarf eigener «Kategorien der Digitalität», die in diesem Essay entwickelt werden. Dazu grenzt sich der Autor von spekulativen Positionen ab, welche die Entwicklung der Digitalisierung derart aufladen, dass daraus utopische Science-Fiction-Szenarien werden. Denn die digitale Lebenswelt sollte nicht nur als eine technologische Innovation verstanden werden, sondern als eine neue ontologische Struktur, die es philosophisch zu erkunden und zu begreifen gilt.
Privat dozieren zum öffentlichen Nutzen - Geschichte der Privatdozierenden an der Universität Zürich
Authors: Koller Christian
Published: June 2022

Die rund 3600 Wissenschaftlerinnen und Wissenschaftler, die seit 1833 als Privatdozierende an der Universität Zürich gewirkt haben, trugen durch ihre Leistungen in Forschung und Lehre wesentlich zum Aufstieg der Institution bei – teilweise ohne jegliche Bezahlung. Ihre Zahl befindet sich heute auf dem historischen Höchststand und sie erbringen rund ein Fünftel der Lehrleistungen. Das Buch stellt erstmals die Geschichte dieses wenig bekannten Teils des Lehrkörpers im Rahmen der Gesamtentwicklung der Universität Zürich und der internationalen Hochschulgeschichte vor, charakterisiert unterschiedliche Typen von Privatdozierenden, portraitiert markante Persönlichkeiten und ihre Leistungen innerhalb und ausserhalb der Universität und spart auch dunkle Punkte der Universitätsgeschichte nicht aus.

Published: June 2022

The purpose of the study is to study the main criteria that ensure the development of the regional agricultural industry. Since the development of the subjects of Russia is based on the need to search for new management tools that ensure the long-term development of all sectors of the national economy, state support and state regulation play a special role in the management of the industry. The research focuses on two groups of industry development. The first group includes labor, natural, material, technical and financial resources. The second group includes investment, information, innovation, research and production, and socio-infrastructural resources. However, the second group of resource base factors has a direct impact on the final position of the agricultural sector. As a result, a mechanism for managing the resources of the agricultural sector of the region, based on the growth factors of the agricultural sector, has been identified.

Las organizaciones de descreídos en habla hispana
Authors: Torres Macías Fabián Augusto
Published: June 2022

Las investigaciones referentes a la cuestión religiosa pocas veces abordan temas que se vinculen con la no creencia o el ateísmo. En buena medida debido al desencanto por lo sagrado y al comportamiento histórico de las religiones, son más comunes y notorios los casos de individuos que rechazan lo sobrenatural de forma explícita. Este trabajo expone el proceso histórico de integración de esos individuos en algunas regiones de habla hispana, la eliminación de barreras geográficas gracias a la popularización del internet, la conformación de comunidades ateas, su salida del entorno virtual y el proceso conocido como activismo ateo.
