ÖRGÜTSEL GÜÇSÜZLÜĞÜN İŞ TATMİNİ VE İŞTEN AYRILMA NİYETİ ÜZERİNDEKİ ETKİSİ
Authors: BİLGİNOĞLU Elif , YOZGAT Uğur
Published: March 2021

Güç, örgütsel davranış ve örgüt teorisinde kesinlikle en önemli bilimsel araştırma alanlarından biridir. Bu yüzden de çeşitli araştırmalarda, farklı teorik bakış açılarıyla incelenmiştir. Her biri gücün farklı yönlerine odaklanan bu yaklaşımlar, örgütlerde güç üzerine olan kavrayışımıza katkıda bulunmuşlardır. Ancak literatür tarandığında, güç üzerine olan araştırmaların örgütlerde güçsüzlüğü göz ardı etmekte oldukları görülmektedir. Oysa örgütlerde güçsüzlük, pek çok kişi tarafından yaşanan temel bir durumdur ve bu konunun detaylı bir şekilde araştırılması önem taşımaktadır. Bu araştırma örgütlerde güçsüzlük üzerine teorik bir çerçeve sunuyor olması yanı sıra, örgütlerde güçsüzlüğün iş tatmini ve işten ayrılma niyeti üzerindeki etkisini inceleyen bir çalışmayı da içermektedir. Bu amaçla İstanbul’da çalışan 276 kişi üzerinde anket uygulanmıştır. Araştırma sonuçları örgütlerde güçsüzlüğün iş tatmini üzerinde negatif, işten ayrılma niyeti üzerinde ise pozitif etkisi olduğunu, bununla birlikte iş tatmininin örgütlerde güçsüzlük ve işten ayrılma niyeti arasında aracı değişken etkisi olduğunu ortaya koymaktadır.

Das Selbst bedarf, um in Erscheinung treten zu können, der Objekte in der Außenwelt, die es triebhaft besetzt. Der Analytiker wie auch der Patient stehen mit ihren Empfindungen, Fantasieprodukten und Objektrepräsentanzen sowie mit dem außen verorteten Gegenüber in anhaltendem Austausch. Sie tauschen sich, bewusst und vorbewusst, in einem spezifischen Setting, über welches eine Übereinkunft gefunden worden ist, in asymmetrischer Weise und mit verschiedenen Aufgaben aus. Die Squiggle-Technik von Winnicott, an einem Fallbeispiel mit einem Kind erläutert, führt in einem virtuellen Übergangsraum von Bildern zur Sprache. Der Analytiker, ungeschützter als im klassischen Setting, ist mit seiner Rêverie im Wachzustand Mit-Erzeuger, Begleiter, Betrachter, Transformierer und Deuter bei der rätselhaften Reise ins Unbekannte. Durch die Übertragungs-/Gegenübertragungs-Abläufe bewegt, muss er sich reflektierend anhaltend wiederherstellen. Im Dazwischen von sowohl intrasubjektiven als auch interpersonalen Grenzzonen ermöglicht er den bildlichen und sprachlichen Metaphern, die als ein gemeinsames Drittes entstanden sind, in ihrem aktuellen Bedeutungsgehalt zur Sprache zu kommen.

The growing dynamism of the intellectualization and logistics of business processes is generating demands for updating the toolkit to assess the enterprise modernization performance and realize its innovative potential. It is argued that the evaluation of modernization efficiency and the design of enterprise innovative development strategies should rely on innovation and R&D trends and achievements. An in-depth study of the external and internal environment in which an enterprise operates helps to reveal the patterns and specifics in its innovation potential assessment paradigm. Thus, the framework to assess the enterprise innovation potential efficiency is based on its production, financial and investment performance evaluation. The consistency in modernization performance suggests following the principles of universality and comparability. Since the use of classical innovation efficiency indicators does not allow for considering the qualitative characteristics of modernization changes, a new framework to assess the modernization performance has been developed which is based on economic and mathematical analysis methods and is aimed at building an integrated index. The integrated index of modernization efficiency will help to determine the modernization potential level, the effects from a range of impact factors on the change of the modernization profile, as well as to reveal the trends of innovative development. This contributes to describing the proposed evaluation framework subject to initial enterprise modernization objectives and its strategic priorities for innovative development. Further research should focus on identifying specific methodological approaches to assessing the performance of modernization changes in line with the overall business strategy to enhance the enterprise innovative potential.

The article discusses the viewpoints of international scholars as to the scientific premises of industrial policy. The industrial policy concept has revealed a wide variety in its understanding. The study provides insights into the evolution of scientific thought and the development of scholarly approaches to understanding of the above concept in the USA and Europe, the most developed economies in the world, where economic theory has been underpinned by considerable scientific debate. The paper offers an ‘industrial policy’ term definition based on the key economic trends and the share of government intervention into industry development. To address the research agenda, a comparative approach and an analytic interpretation method were employed that allowed for identifying the differences in factors that had affected the background for elaborating a range of scientific concepts. The study explores extensive theoretical endeavors all over the world for understanding the industrial policy concept which demonstrates ample scientific discussion on the role of government in economic processes. The fundamental rationale for generalizing the variety of research studies is the compehension of the relationship between economic processes and the government policy in the economy domain. Such approach incorporates the government paternalism towards industry development (embedded in the neoclassical studies of American economists and neoliberal interpretations of the governance function in the industrial sector) and building a competitive economy by enhancing production incentives in a free market environment. The research findings have identified two key vectors in the scientific viewpoints of international scholars, i. e. "vertical" and "horizontal" understanding of the industrial policy concept. The former vector reflects the economic ideology of paternalism, built on protectionism, while the latter demonstrates a neoliberal approach based on industrial sector competitiveness. The implications for further research are outlined as investigating correlations of the effects from government involvement and market factors in a competitive environment.

The paper discusses the specific features of e-business in the world market, as well as identifies its current state and the key development trends. A special emphasis is put that e-commerce as a critical element of a "new economy" is gaining increasingly more practical implications. It is argued that further effective development of world commerce triggers a need to evaluate the main trends and prospects of the e-commerce market which makes the basis of information business. The world economy demonstrates rapid development towards building global economic space to give rise to a new type of economy. In this context, the need to provide more insights into the role and significance of Ukraine in this environment seems relevant and timely. The global economic space enhances the elimination of barriers to the movement of goods, services and capital, speeding up payment transactions, as well as contributes to harmonization of market regulation. The authors suggest avoiding hasty conclusions as to the readiness of the Ukrainian economy to the total integration into the free market system without verified findings from rigorous research. The study provides evidence that digital globalization of economic processes is becoming a fundamental trend and a driver of the overall modern economy development which has been underpinned by a number of revolutionary technological advances along with the general patterns of economic evolution that guides modern management to be sensitive to the rules of doing business, encourages labour productivity and product quality increase, helps to smooth the recession phases of the economic cycle, etc. The study findings demonstrate that a major effect of digital globalization is international economic integration which spurs non-traditional cross-border flows of goods, rapid loan and investment growth, fosters global exchange of information, ideas and technologies, thus contributing to a transformation of national economies into single global economy. However, it is argued that excessive national protectionism can hamper the development of the global digital economy. Moreover, the desire to store all data solely on the national servers and unjustified protection of confidential information will create extra barriers to cross-border trade and inhibit globalization of the world digital economy.

Despite vast research has been carried out and a great number of approaches are available to assess the economic security of enterprises, currently a range of security-related issues are yet beyond the research agenda, thus triggering a need for their thorough investigation and interpretation, in particular this refers to a contradictedness concept underpinned by the inverse relationship between its level (state) and a management decision which can be effective subject to certain economic indicators. The purpose of this study is to develop theoretical and methodological approaches to assess the enterprise economic security with due regard to management decisions effectiveness. To attain the research objectives, the following research methods have been employed: generalization – to draw conclusions from a primary sources content analysis, analysis and synthesis – to provide deeper understanding of the key research categories along with specifying the economic security indicators. The study suggests an ambivalent approach to the perception of management decisions. Using the example of a decision made as to the implementation of an investment project, it is demonstrated that, in contrast to the existing approaches (in which it is viewed as an anti-crisis measure and a tool to boost the level of economic security), in fact, the project may be effective from the position of enhancing the key economic indicators, however it will fail from the perspective of increasing the level of economic security. In this context, the indicators of the investment project economic efficiency have been updated with a focus towards enhancing the enterprise economic security. The study presents an algorithm to test the investment feasibility together with evaluating its impact on the level and the state of the enterprise economic security. The authors also provide a classification of effects from management decisions aimed at increasing the level of economic security. In addition to the above, a chain modeling algorithm is proposed to assess the state of economic security taking into account the rate of change in reaching by security indicators (and its individual elements) their liminal values. The use of this algorithm allows to predict the effects of multiple alternatives in management decision-making on the state of the enterprise economic security. An improved brute force methodological approach applied to investing in processes (projects) to ensure the enterprise economic security provides for a more balanced approach when making appropriate management decisions. The proposals made have important practical implications since they expand the management analytics capabilities and allow to consider the effects from management decisions on the enterprise economic security.

Emotional intelligence plays a very important role for a leader because it can help the effectiveness of coach leadership among trainees and can even guarantee the transfer of training that has been given to trainees. When there is a failure to curb this situation will have a more negative impact on organizations and individuals, and if it is not proactively addressed. Therefore, this study aims to identify the level and relationship between emotional intelligence and leadership effectiveness among coaches. A total of 74 sets of questionnaires were distributed to respondents who have participated in the Transformation Program (Team Building) organized by XYZ training center on October 20, 2018 until October 22, 2018. Descriptive analysis shows the results of the study on emotional intelligence level and leadership effectiveness among coaches. While the correlation analysis proves that there is a significant relationship with r = 0.828 between emotional intelligence and leadership effectiveness among coaches. Thus, this study has shown that emotional intelligence has a significant relationship with leadership effectiveness among coaches.

This article is a study on the concept of individual skills (Interpersonal skills) according to the perspective of the Qur'an and Sunnah. Writing and research related to individual skills according to Islamic perspective are hard to find, most of the writing-related to it is from Western scholars and of course according to their perspective. Such a situation occurs in most fields of knowledge that are professional, it does not happen in the field or discipline of knowledge that is core. Accordingly, it is not something that is difficult to interpret because this field of Interpersonal skills has been developed and processed as a professional field by Western scholars. The situation is in line with the development of secular Western civilization based on the separation of knowledge from religion and morality from life. This writing is based on qualitative methodology through observational and research approach which is later through the method of formulation of the nusus al-Quran and al-Sunnah. The texts will be analyzed to formulate key themes related to the concept of individual skills.

Published: March 2021

El adenocarcinoma colorrectal es la tercera causa de muerte por cáncer en mujeres y la cuarta en hombres a nivel mundial. Se diagnostica en su mayoría en pacientes mayores a los 50 años, siendo la edad media al momento del diagnóstico los 72 años. A pesar eso, se estima que en los próximos años aumentará la incidencia en personas jóvenes y de mediana edad. Debido a esta proyección y considerando que la ausencia de signos y síntomas específicos no permite un diagnóstico oportuno, se hacen necesarias la sensibilización clínica y un alto índice de sospecha en las presentaciones atípicas. Se presenta el caso de una paciente joven que consulta por un cuadro de un mes de síntomas respiratorios quien, después de tratamiento antibiótico, antiviral e inmunomodulador sistémico, presenta sepsis de origen abdominal por peritonitis de cuatro cuadrantes secundaria a perforación de colon sigmoide debida a adenocarcinoma bien diferenciado, metastásico a pulmón, que la llevó a la muerte.

Published: March 2021

La integración entre el equipo de salud y su comunidad de referencia es una de las condiciones operativas, y conceptuales, de la Atención Primaria de la Salud. Con el fin de evaluarla, se realizó una investigación en las Salas de Atención Primaria de la Salud de la Ciudad de Corrientes. Se utilizó un método exploratorio orientado desde una perspectiva interpretativa-cualitativa. 30 alumnos de la Carrera de Medicina de la Universidad Nacional del Nordeste fueron capacitados a tal efecto. Se realizaron observaciones in situ y entrevistas semi-estructuradas al personal de salud y a usuarios de las salas. Se realizó un análisis de contenido, esquematizado en un sistema de categorías preestablecidas y enriquecido con subcategorias inducidas a partir del análisis de la información. Como facilitadores para la integración, se encontró por parte del personal del equipo: conocimiento de los problemas de la zona, residencia en el barrio, buena accesibilidad a la atención y respuesta adecuada a la demanda; y por parte de la población: predisposición a participar. Como barreras para la integración: diferencias de conceptos respecto al rol del primer nivel de atención entre equipo de salud y comunidad y escasa integración de algunos profesionales. Se concluyó con que existen factores favorecedores importantes que habría que aprovechar y potenciar; en tanto, habría que trabajar sobre las barreras, comenzando por el rol fundamental que para esto tiene el equipo de salud. La mejor identificación de categorías que ha permitido este trabajo propicia la realización de estudios de mayor profundidad.

Published: March 2021

Rapid developments in science require the application of new technologies in the field of education, aiming at changing the traditional and obsolete ways of teaching, providing ground for new forms. These new forms of teaching do not replace the teacher but adapt his role from omniscient to mentor and role model for students. With the use of technological means and the teacher's contribution to the teaching of the courses, the results in learning - let alone in the understanding of specialty courses- can be even more remarkable and bring about changes and perspectives for new approaches in the field of education. The aim of this survey was to investigate the use of new technologies by teachers today in the teaching of specialty courses and to what extent this implementation can improve the learning process. The results of the research show that our sample not only has a positive attitude towards the use of new forms of technology in the teaching of specialty courses but also seems to understand the benefits that arise from their use for the teachers themselves, for students, and the whole educational process.
Academist Perceptions on the Use of Web 2.0 Tools Through Maslow's Needs Hierarchy: A Case Study
Authors:   Kafkas University, Turkey, YILDIZ Ezgi Pelin
Published: March 2021

The theory known as the ‘Maslow Hierarchy of Needs’, which was put forward by Abraham Maslow as a result of scientific studies, describes the basic requirements that guide human behaviour. In this hierarchical order, needs in five groups are physiological needs, safety needs, belonging and love needs, esteem needs and self-actualisation needs. Nowadays, it is not difficult to observe that human life has undergone a radical metamorphosis with digital transformation. With the cultural transformation triggered by digital technologies in the postmodern world, Maslow's theory has been transformed. In light of all this, in this study, based on Maslow's transforming hierarchy of needs pyramid, it is aimed to reveal academician perceptions about the use of Web 2.0 tools. The study was conducted with a case study, one of the qualitative research methods. A case study is an empirical research method used, where more than one source of evidence or data is available. The study group of the research consists of 20 academicians working in different departments of a government state university. Academist perceptions’ interview form for ‘Use of Web 2.0 tools through the needs hierarchy of Maslow, which was developed by the researcher as a data collection tool’, was used in the research. The relevant form consists of demographic and open-ended questions. As a result, it has been observed that the views obtained from academics generally meet Maslow's Digital Needs Pyramid.

Maintenance or Change? Examining the Reinforcing Spiral Between Social Media News Use and Populist Attitudes
Authors: Schumann Sandy , Thomas Fabian , Ehrke Franziska , Bertlich Tisa , Dupont Julia Christina
Published: March 2021

Citizens around the world increasingly express support for populism. Here, we apply the reinforcing spirals model to examine whether, and how, social media news use shapes populist attitudes over time. Specifically, we assess if using social media as a news source serves to maintain existing populist attitudes or facilitates a shift in attitudes to a more extreme position. A cross-sectional survey (N1 = 195) highlighted a positive correlation between social media news use and populist attitudes. A four-wave longitudinal survey (N2 = 386) further showed that this relationship reflects media and selection effects. Over a period of three months, more frequent social media news use predicted stronger populist attitudes at subsequent measuring points. In addition, higher levels of populist attitudes were related to more frequent social media news consumption in the following waves. However, the frequency of social media news use did not change over time and populist attitudes did not become stronger during the study period. Taken together, the findings indicate that social media news use contributed to the maintenance of populist attitudes at a stable level. There is no evidence to suggest social media news use predicted more extreme populist attitudes. We discuss these results with respect to the (potentially continued) rise of populism; we also critically reflect on the phenomenon of attitude polarization online.

Published: March 2021

BackgroundRe-purposed medicines may have role in combating the SARS-CoV-2 virus. The antiparasitic medicine ivermectin, which has anti-viral and anti-inflammatory properties, has been tested in numerous clinical trials with promising results.MethodsWe assessed the efficacy of ivermectin treatment and/or prophylaxis among people with, or at high risk of covid-19 infection. We searched bibliographic databases up to February 2021 and two review authors sifted for studies, extracted data and assessed risk of bias. Meta-analyses were conducted and certainty of the evidence was assessed using the GRADE approach.FindingsTwenty-one RCTs involving 2741 participants met review inclusion. Meta-analysis of 13 trials found ivermectin reduced risk of death compared with no ivermectin (average Risk Ratio 0.32, 95% confidence interval (CI) 0.14 to 0.72; n=1892; I2=57%; low to moderate-certainty evidence. Low certainty evidence found ivermectin prophylaxis reduced covid-19 infection by an average 86% (95% CI 79% to 91%). Secondary outcomes provided very-low or low certainty evidence. Low certainty evidence suggests that that there may be no benefit with ivermectin for ‘need for mechanical ventilation’, whereas effect estimates for ‘improvement’ and ‘deterioration’ favoured ivermectin use. Severe adverse events were rare and evidence of no difference was assessed as low to very low certainty. Evidence on other secondary outcomes was very low certainty.InterpretationLow to moderate-certainty evidence suggests reductions in covid-19 deaths and infections may be possible by using ivermectin. Employing ivermectin early on may reduce the number of people progressing to severe disease. The apparent safety and low cost suggest that ivermectin could have an impact on the SARS-CoV-2 pandemic globally.FundingNoneKeywords: ivermectin, prophylaxis, prevention treatment, covid-19, SARS-CoV-2

Interaction with a machine teacher improves student learning outcomes and teaching effectiveness. Results with Wiley Daila from Indonesia
Authors: Pelzer Elena
Published: March 2021

With the increase in demand for online learning, machine teachers are becoming an important technology in higher education since they are expected to improve teaching effectiveness and student learning outcomes. However, machine teachers require an aptitude for technology and are associated with high initial costs. Thus, here we use a more basal form of a machine teacher that enhances the interaction but does not require advanced technological competency. In a survey study from two universities in Indonesia, we investigate how the machine teacher Wiley Daila affects the teaching and learning environment. The findings indicate that Daila is perceived as useful and increases perceived teaching effectiveness and student learning outcomes. The study also shows that more research is needed to better understand the nuances in interaction.

Experimental Investigation on Loading-Relaxation Behaviors of Shear-Zone Soil
Authors: Cui Deshan , wang shun , Cheng Qiong , Wu Wei
Published: March 2021

This paper presents an experimental investigation on the loading-relaxation behaviors of reconstituted shear-zone soils through drained triaxial tests. A multistage loading-relaxation approach is adopted to perform this test. The test aims to study two main issues: the influence of relaxation on the mechanical response during reloading; and the influence of strain rates, loading increments, and the relaxation time on the relaxation characteristics. The test results indicate that the stress-relaxation behavior of shear-zone soil is dependent on the stress and strain levels. The loading patterns prior to the stress-relaxation process affect mainly the viscoelastic behavior of the soil and subsequently influence the initial relaxation behavior. Moreover, a reloading after a stress-relaxation process gives rise to a higher deviatoric stress owing to the viscoplastic hardening. It is further shown that the loading-relaxation behaviors can be interpreted by the viscoplastic theory.
Reality in a sphere: A direct comparison of social attention in the laboratory and the real world
Authors: Großekathöfer Jonas David , Seis Christian , Gamer Matthias
Published: March 2021

Humans often show reduced social attention in real situations, a finding rarely replicated in controlled laboratory studies. Virtual reality is supposed to allow for ecologically valid and at the same time highly controlled experiments. This study aimed to provide initial insights into the reliability and validity of using spherical videos viewed via a head-mounted display (HMD) to assess social attention. We chose five public places in the city of Würzburg and measured eye movements of 44 participants for 30 seconds at each location twice: Once in a real environment with mobile eye tracking glasses and once in a virtual environment playing a spherical video of the location in an HMD with an integrated eye tracker. As hypothesized,participants demonstrated reduced social attention with less fixations on passengers in the real environment as compared to the virtual one. This is in line with earlier studies showing social avoidance in interactive situations. Furthermore, we observed more consistent fixation patterns in virtual environments. These findings highlight that the potential for social interactions and an adherence to social norms are essential modulators of viewing behavior in social situations and cannot be easily simulated in laboratory contexts. However, spherical videos might be helpful for supplementing the range of methods in social cognition research and other fields. Data and analysis scripts are available at https://osf.io/hktdu/.
The Art of Feeling Different: Exploring the Diversity of Emotions Experienced During an Art Museum Visit
Authors: Rodriguez Rebekah , Fekete Anna , Silvia Paul , Cotter Katherine N.
Published: March 2021

The aesthetic experience of a group of artworks—such as an afternoon spent wandering in a museum—is not simply the sum of experiences of the individual works. In the present research, we explored visit-level aesthetic experiences in a field study of 298 visitors to a museum of modern and contemporary art. In particular, we focused on emotional diversity: the richness, complexity, and heterogeneity of the emotions that people experienced during their visit. After their visit, participants reported the degree to which they experienced, if at all, 10 emotions, from which we calculated diversity metrics reflecting their emotional variety (the number of emotions experienced) and emotional balance (the relative evenness between emotions or dominance of a single emotion) during the visit. Overall, the sample reported a rich aesthetic experience, but there was wide and predictable variability. Among other findings, emotional variety was higher for people with greater openness to experience and among first-time visitors to the museum; emotional balance was higher among people high in openness to experience and people with greater interest in art. The concept of diversity—the richness and complexity of someone’s emotional experience of the arts—appears promising for understanding holistic aesthetic experiences, such as entire museum visits rather than single works, as well as for many other questions in empirical aesthetics.
Bayesian modeling of item heterogeneity in dichotomous recognition memory data and prospects for computerized adaptive testing
Authors: Güsten Jeremie , Berron David , Duzel Emrah , Ziegler Gabriel
Published: March 2021

Most current models of recognition memory fail to separately model item and person heterogeneity which makes it difficult to assess ability at the latent construct level and prevents the administration of adaptive tests. Here we propose to employ a General Condorcet Model for Recognition (GCMR) in order to estimate ability, response bias and item difficulty in dichotomous recognition memory tasks. Using a Bayesian modeling framework and MCMC inference, we perform 3 separate validation studies comparing GCMR to the Rasch model from IRT and the 2-High-Threshold (2HT) recognition model. First, two simulations demonstrate that recovery of GCMR ability estimates with varying sparsity and test difficulty is more robust and thatestimates improve from the two other models under common test scenarios. Then, using a real dataset, face validity is confirmed by replicating previous findings of general and domain-specific age effects (Güsten et al., 2021). Using cross-validation we show better out-of-sample prediction for the GCMR as compared to Rasch and 2HT model. Finally, an adaptive test using the GCMR is simulated, showing that the test length necessary to obtain reliable ability estimates can be significantly reduced compared to a non-adaptive procedure. The GCMR allows to model trial-by-trial performance and to increase the efficiency and reliability of recognition memory assessments.

We emphasize key aspects of the field, including accessibility, urban change, and spatial interaction and behavior, providing a high-level research agenda that indicates a variety of gaps and routes for future research that will not only lead to more equitable and aware solutions to local and global challenges, but also innovative and novel research methods, concepts, and data. We close with a set of gender, representation, and inclusion challenges to our discipline, researchers, and publication outlets.
Four Years of Fake News. A Quantitative Analysis of the Scientific Literature
Authors: Righetti Nicola
Published: March 2021

Introduction: Since 2016, “fake news” has been the main buzzword for online misinformation and disinformation. This term has been widely used and discussed by scholars, leading to hundreds of publications in a few years. This report provides a quantitative analysis of the scientific literature on the topic published up to 2020.Methods: Documents mentioning the keyword “fake news” have been searched in Scopus, a large multidisciplinary scientific database. Frequency analysis of metadata and automated lexical analysis of titles and abstracts have been employed to answer the research questions. Results: 2,368 scientific documents mentioned “fake news” in the title or abstract, published by 5,060 authors and 1,225 sources. Until 2016 the number of documents mentioning the term was less than 10 per year, suddenly rising from 2017 (203 documents), and steadily increasing in the following years (477 in 2018, 694 in 2019, and 951 in 2020). Among the most prolific countries are the USA and European countries such as the UK, but also many non-Western countries such as India and China. Computer Science and Social Sciences are the disciplinary fields with the largest number of documents published. Three main thematic areas emerged: computational methodologies for fake news detection, the social and individual dimension of fake news, and fake news in the public and political sphere. There are 10 documents with more than 200 citations, and two papers with a record number of citations (Alcott & Gentzkow, 2017; Lazer et al., 2018).Conclusions: Research on “fake news” keeps on the rise, with a marked upward trend following the 2016 USA Presidential election. Despite having been the subject of debate and also criticism, the term is still widely used. A strong methodological interest in fake news detection through machine learning algorithms emerged, which – it can be argued – can be profitably balanced by a social science approach able to unpack the phenomenon also from a qualitative and theoretical point of view. Although dominated by the USA and other Western countries, the research landscape includes different countries of the world, thus enabling a wider and more nuanced knowledge of the problem. A constantly growing field of study like the one concerning fake news requires scholars to have a general overview of the scientific productions on the topic, and systematic literature reviews can be of help. The variety of perspectives and topics addressed by scholars also means that future analyses will need to focus on more specific topics.
Who wants technocrats? A comparative study of citizen attitudes in nine young and consolidated democracies
Authors: Chiru Mihail , Enyedi Zsolt
Published: March 2021

Technocratic cabinets and expert, non-political ministers appointed in otherwise partisan cabinets have become a common reality in recent decades in young and older democracies, but we know little about how citizens see this change and what values, perceptions and experiences drive their attitudes towards technocratic government. The article explores the latter topic by drawing on recent comparative survey data from 9 countries, both young and consolidated democracies from Europe and Latin America. Two individual-level characteristics trigger particularly strong support for the replacement of politicians with experts: low political efficacy and authoritarian values. They are complemented by a third, somewhat weaker factor: corruption perception. At macro level, technocracy appeals to citizens of countries where the quality of democracy is deficient and where technocratic cabinets are part of historical legacy. Surprisingly, civic activism, and partially satisfaction with democracy, enhance technocratic orientation, indicating such attitudes are not expressions of alienation or depoliticization.
Academist Perceptions on the Use of Web 2.0 Tools Through Maslow's Needs Hierarchy: A Case Study
Authors: YILDIZ Ezgi Pelin
Published: March 2021

The theory known as the ‘Maslow Hierarchy of Needs’, which was put forward by Abraham Maslow as a result of scientific studies, describes the basic requirements that guide human behaviour. In this hierarchical order, needs in five groups are physiological needs, safety needs, belonging and love needs, esteem needs and self-actualisation needs. Nowadays, it is not difficult to observe that human life has undergone a radical metamorphosis with digital transformation. With the cultural transformation triggered by digital technologies in the postmodern world, Maslow's theory has been transformed. In light of all this, in this study, based on Maslow's transforming hierarchy of needs pyramid, it is aimed to reveal academician perceptions about the use of Web 2.0 tools. The study was conducted with a case study, one of the qualitative research methods. A case study is an empirical research method used, where more than one source of evidence or data is available. The study group of the research consists of 20 academicians working in different departments of a government state university. Academist perceptions’ interview form for ‘Use of Web 2.0 tools through the needs hierarchy of Maslow, which was developed by the researcher as a data collection tool’, was used in the research. The relevant form consists of demographic and open-ended questions. As a result, it has been observed that the views obtained from academics generally meet Maslow's Digital Needs Pyramid.
Science, technology, and ecological crisis: Examining ecological modernization theory through patent data
Authors: Bugden Dylan
Published: March 2021

Ecological modernization refers to the process through which the state and industry resolve ecological crises through radical improvements in resource efficiency and the substitution of environmentally harmful industrial processes for less harmful ones without undermining existing relations of economic production. While numerous studies cast doubt on the theory of ecological modernization, existing analyses do not fully address the theory’s core hypothesis on the relationship between technological innovation and environmental impacts. I resolve this problem by using newly available global patent data on environmental technologies across 35 countries from 1982-2016. Results demonstrate that as a nation’s technology sector increases its development of environmental technologies, its per capita ecological footprint declines. However, the marginal effect of technological development is too small to offer a meaningful path toward ecological sustainability through technological innovation alone. I conclude by remarking on the implications of this study for social theory and environmental policy.

Facile Synthesis of Nanosized Magnesium-Aluminium Layered Double Hydroxides
Authors: Dhakal Kedar Nath , Aryal Girja Mani , Adhikari Hari Sharan , Adhikari Rameshwar
Published: March 2021

We report facile methods of preparing nanosized hydrotalcite-like compounds, the layered double hydroxides (LDH), with ordinary chemistry laboratory settings to educate the young scientists from high schools to undergraduate university level fostering their research interest in preparing these nanomaterials of practical importance. Coprecipitation and urea hydrolysis methods have been recommended as facile routes of preparing the magnesium-aluminum layered double hydroxides (Mg-Al LDHs). The LDH thus prepared were characterized by Fourier transform infrared (FTIR) spectroscopic and powder X-ray diffraction (XRD) techniques. The observed weakening of some FTIR peaks and XRD planes shifting concerning standard JCPDS 89-5434 data implied the slight structural variation of the compounds and the presence of impurities. The average grain diameter of LDH particles was found in the range of 20 to 60 nm.
