Published: August 2021

AbstrakPenelitian ini bertujuan untuk mengetahui reaksi masyarakat terhadap informasi pandemi Covid yang disampaikan oleh media massa. Penyampaian berbagai berita atau hal yang sejenisnya secara berkali-kali membuat masyarakat mudah faham, dan memiliki dampak ketidakpercayaan jika tidak sesuai dengan faktanya. Penelitian ini mencoba untuk mengungkap dan menemukan bahwa media massa secara simultan dapat meningkatkan kepercayaan tentang covid-19 atau sebaliknya. Penelitian ini berbeda dengan yang lainnya, dikarenakan bahwa media yang secara simultan malah membuat ketidakpercayaan secara penuh terhadap pemberitaan yang disampaikan. Metode yang digunakan dalam penelitian ini adalah deskriptif kuantitatif secara pusposive sampling terhadap para mahasiswa yang sekarang lagi belajar secara daring dan selalu dekat dengan berita di media sosial. Responden dalam penelitian ini adalah 300 mahasiswa yang terdiri dari tujuh kampus di Provinsi Kalimantan Selatan, Indonesia. Berdasarkan hasil temuan, penelitian ini menyimpulkan bahwa informasi yang disampaikan berulang kali tentang Covid akhirnya membuat masyarakat kurang peduli terhadap Covid. Hal ini dibuktikan dengan munculnya fakta terbalik dari berita dari berbagai media massa.Kata kunci: Persepsi, media, fakta, simultan, masyarakat AbstractThis study aims to determine the public's reaction to the Covid pandemic information conveyed by the mass media. Repeatedly conveying various news or similar things makes it easy for the public to understand, and has an impact of distrust if it is not by the facts. This study tries to uncover and find that mass media can simultaneously increase beliefs about Covid-19 or vice versa. This study is different from the others because the media simultaneously make complete distrust of the news delivered. The method used in this research is descriptive quantitative by purposive sampling of students who are currently studying online and are always close to the news on social media. Respondents in this study were 300 students from seven campuses in South Kalimantan Province, Indonesia. Based on the findings, this study concluded that the information that was repeatedly conveyed about Covid ultimately made the public less concerned about Covid. This is evidenced by the emergence of upside-down facts from the news from various mass media.Keywords: Perception, media, facts, simultaneous, society
EEBO and Us

Published: August 2021

This essay responds to criticisms leveled against “How to Think About EEBO” (Gavin [2017] 2019). While my history of Early English Books Online was faulted for paying insufficient attention to the experiences of scholars using the collection, I argue that using digital tools for literary and bibliographical research can create a false sense of mastery that leaves scholars blind to the features of digital textuality that are most important historically and theoretically.

Authors: Zhao Jin 
Published: August 2021

Zusammenfassung
Der Beitrag geht auf die Diskussion über die Universalität oder die Kulturgebundenheit von Fachtexten sowie die Relativitätshypothese über Fachtexte in der Fachsprachenforschung ein und vertritt die Ansicht, dass wissenschaftliche Texte durch die Kultur geprägt sind. Im Beitrag werden deutsche und chinesische linguistische Zeitschriftenartikel hinsichtlich der Makrostruktur kontrastiv analysiert, um zu zeigen, dass in derselben wissenschaftlichen Gemeinschaft wissenschaftliche Texte auch sprachkulturell bedingte Unterschiede aufweisen.
Computational analysis of heat and mass transfer in a micropolar fluid flow through a porous medium between permeable channel walls
Authors: Ahmad Sohail , Ashraf Muhammad , Ali Kashif , Nisar Kottakkaran Sooppy 
Published: August 2021

Abstract
The present work numerically investigates the mass and heat transport flow of micropolar fluid in a channel having permeable walls. The appropriate boundary layer approximations are used to convert the system of flow model equations in ODEs, which are then numerically treated with the quasi-linearization method along with finite difference discretization. This technique creates an efficient way to solve the complex dynamical system of equations. A numerical data comparison is presented which assures the accuracy of our code. The outcomes of various problem parameters are portrayed via the graphs and tables. The concentration and temperature accelerate with the impacts of the Peclet numbers for the diffusion of mass and heat, respectively. It is also found that the porosity of the medium has a substantial effect on the skin friction but low effect on the heat and mass transfer rates. Our results may be beneficial in lubrication, foams and aerogels, micro emulsions, micro machines, polymer blends, alloys, etc.

Abstract

Objectives
Preterm infants are at increased risk for vitamin D deficiency (VDD). We aimed to assess the adequacy of standardized vitamin D supplementation protocol in very low birth weight (VLBW) infants. Additionally, vitamin D status of mother/infant couples and the associations between vitamin D status at birth and morbidities of the infants were investigated.

Methods
In this single-center, prospective cohort study blood samples were collected from 55 mothers just before delivery and from their infants at birth and on the 30th day of life (DOL) for 25 hydroxy vitamin D (25OHD) measurements. Vitamin D was initiated in dose of 160 IU/kg by parenteral nutrition on the first DOL and oral vitamin D supplementation (400 IU/day) was administered when enteral feedings reached 50% of total intake or on the 15th DOL.

Results
The median 25OHD levels of the infants were 16.12 (9.14–20.50) in cord blood and 36.32 (31.10–44.44) in venous blood on the 30th DOL (p<0.01). In 98% of the VLBW infants 25OHD reached sufficient levels on the 30th DOL. None of the mothers had sufficient vitamin D levels (25OHD >30 ng/mL). Maternal 25OHD levels were correlated with the 25OHD levels of the infants in cord blood (r=0.665, p<0.001). There was a significant difference in mean cord 25OHD levels between winter (13.65 ± 5.69 ng/mL) and summer seasons (19.58 ± 11.67 ng/mL) (p=0.021). No association was found between neonatal morbidity and vitamin D status.

Conclusions
The results clearly show that by utilizing the current supplementation protocol, the majority of VLBW infants with deficient/insufficient serum 25OHD levels reached sufficient levels on the 30th DOL. Furthermore, vitamin D levels in mother/infant couples were found to be highly correlated.
Left-wing extremist violence: Risk and protective factors in a targeted sample of potential extremists

Published: August 2021

ZusammenfassungWährend in den vergangenen Jahren die Forschung zum politisch rechtsorientierten und religiös-islamistischen Extremismus zunahm, blieb eine ähnliche Entwicklung beim Linksextremismus aus. Die vorliegende Studie untersucht spezifische Risiko- und Schutzfaktoren des Linksextremismus. Die Daten stammen aus einer Onlinebefragung mit 144 potentiellen Linksextremen, die wir mittels eines Online-Fragebogens u. a. über einschlägige linksaffine und -extreme Gruppierungen rekrutierten. Wir konzentrierten uns in unserer Studie auf aggressives und gewalttätiges Verhalten (nicht nur auf Einstellungen). 51 % unserer Teilnehmer waren männlich, das Durchschnittsalter warM= 26.74 (SD= 6.11). 92 Teilnehmer berichteten, politisch motivierte Gewalt gegen Personen und/oder Sachen begangen zu haben. Erhoben wurden theoretisch fundierte Einflussfaktoren der Person und des sozialen Umfelds. Eine hierarchische Regression konnte circa 50 % der Varianz der Gewalttätigkeit aufklären. Die Integration in ein gewaltbereites extremistisches Netzwerk hing deutlich mit der Durchführung extremistisch motivierter Gewalt zusammen. Eine persönliche kriminelle Vorgeschichte ging ebenfalls mit mehr politischer Gewalt einher. Wahrnehmungen von prozeduraler Gerechtigkeit und Legitimität konnten als Schutzfaktoren identifiziert werden. In einer explorativen Diskriminanzanalyse untersuchten wir Unterschiede zwischen Personen, die »nur« Gewalt gegen Sachen ausgeübt hatten, und jenen, die auch Gewalt gegen Personen berichteten. Gewaltorientierte extremistische Einstellungen waren der wichtigste Aspekt bei der Vorhersage der Gruppenzugehörigkeit. Die Ergebnisse werden theoretisch eingeordnet sowie Stärken und Schwächen der Studie diskutiert. Mehr empirische Untersuchungen zum Linksextremismus sind nötig, insbesondere solche mit einem längsschnittlichen Design.
Micro and macro-level risk factors for extremism and terrorism: Toward a criminology of extremist violence
Authors: LaFree Gary , Schwarzenbach Anina 
Published: August 2021

AbstractOver the past twenty years, research onpolitical extremismandterrorismhas become one of the fastest growing sub-fields within criminology. This rapid growth is reminiscent of the early years ofcriminologyitself, characterized by energy, imagination and creativity but at the same time a specialization struggling to collect and analyze valid data, apply appropriate research methods and develop coherent theoretical frameworks. In this paper, we take stock of these developments by considering a basket ofmicro- and macro-level risk factorsthat have been frequently linked to the decision to engage in violent extremism. Following a review of risk factors, we consider major definitional, theoretical, data and methodological challenges and also progress made. Prior criminological research on violent extremism has focused especially on micro-level characteristics and few studies to date have integrated micro and macro determinants to explain extremist outcomes. However, with the growing availability of data, including open-source databases, paired with the application of more sophisticated statistical methods, we expect to see more robust results in the years ahead.
Perceived injustice, perceived group threat and self-reported right-wing violence: An integrated approach
Authors: Williamson Harley , De Buck Ann , Pauwels Lieven JR 
Published: August 2021

AbstractThe present study seeks to explain individual differences in self-reported politically motivated violence and vandalism, and participation within an extreme right-wing group. While violent extremism is highly debated, few criminological studies explicitly test factors that can trigger violent extremism. The present study addresses this gap by integrating two different frameworks: a perceived injustice and group threat-initiated model and an impulsivity-initiated model. We also investigate several intervening mechanisms. We draw on a sample of 705 adolescents and young adults living in Flanders, Belgium to test the strength of direct and intermediary effects of perceived injustice, perceptions of out-group threat from Jewish populations, ethnocentrism, feelings of superiority, moral support for right-wing extremism, and exposure to racist peers on politically motivated violence and vandalism. Results of structural equation models (SEM) indicate various direct and intermediary effects between both perceived injustice and violent extremism, and between impulsivity and violent extremism. Our model reveals the complex and intricate antecedents of violent extremism. Importantly, we find that feelings of injustice and unfair treatment are a major source of extremist violence, as they easily trigger often debated causes such as high in-group identification and ethnocentrism. Implications of these findings for preventing violent extremism are discussed, given the centrality of perceptions of injustice and threat.
Adsorption of biopolymers onto nanocelluloses for the fabrication of hollow microcapsules
Authors: Lombardo Salvatore , Cathala Bernard , Villares Ana 
Published: August 2021

AbstractIn this work, we studied the multilayer adsorption of cellulose nanocrystals and cellulose nanofibers with other polysaccharides such as xyloglucan and chitosan. We showed that the specific interactions between these biopolymers can be exploited to prepare three-dimensional functional materials. Quartz crystal microbalance studies showed that both biopolymers were adsorbed irreversibly on the nanocellulose surfaces. In aqueous media, the maximum amount of adsorbed polymer was higher for the smaller and more crystalline cellulose nanocrystals, compared to cellulose nanofibers. For both nanocelluloses employed, the amount of xyloglucan of the first bilayer was larger than the amount of chitosan adsorbed. Ellipsometry showed that both xyloglucan and chitosan were adsorbed on nanocellulose surfaces. However, at the second layer no mass change was detected by quartz crystal microbalance when xyloglucan was added, while for addition of successive layers of chitosan a decrease of frequency was detected. The water uptake of multilayers was higher for cellulose nanocrystals than for nanofibers, which was ascribed the presence of voids in the nanocrystal layer. Finally, we demonstrated that multilayer adsorption of these biopolymers can be performed on calcium carbonate sacrificial templates, which can then be removed to yield hollow polysaccharide microcapsules.

Abstract
The purpose of the present work is to enhance the thermal stability and rheological properties of semi-interpenetrating polymer network (IPN) hydrogel based on partially hydrolyzed polyacrylamide/hydroxypropyl guar (HPAM/HPG) nanocomposite reinforced with graphene oxide (GO), at temperatures (200 and 240 °F) for use in oil recovery applications. FTIR spectra of the IPN nanocomposite hydrogels revealed interactions of GO with HPAM/HPG chains. An increase in the viscosity is also observed from the rheological study. Moreover, IPN and its nanocomposite hydrogels exhibited non-Newtonian behavior. The decline of viscosity of IPN nanocomposite hydrogels was observed with an increase in the temperature from 200 to 240 °F but was still higher than IPN hydrogel without GO. Dispersion of GO through the HPAM/HPG hydrogel matrix was evaluated by SEM morphology and electrical conductivity. The IPN nanocomposite hydrogels showed high viscosity stability, thermal stability, and flow activation energy as compared to IPN hydrogel without GO. Therefore, the addition of 0.1 wt.% of GO to the HPAM/HPG matrix is suitable to create a cross-linked polymer solution with improved properties which may be beneficial for use in oil recovery applications.
Unbalanced Scales of Global Capitalism: Analyzing Temporary Foreign Worker Programs in Canada
Authors: Callon Emma 
Published: August 2021

This article analyzes several characteristics of two of Canada’s Temporary Foreign Worker Programs (TFWPs): The Seasonal Agricultural Worker Program (SAWP) and the Live-in Caregiver Program (LCP). First, I consider the social and economic contexts in which these programs have emerged. Second, I discuss how these programs maintain racial and gendered hierarchies. Third, I problematize the relationship TFWPs have with citizenship status, as well as critique TFWPs as a long-term solution to Canadian labour shortages. Last, I discuss the potential benefits of these TFWPs and suggest alternatives and potential improvements to the programs. Using a Marxist framework, this analysis situates Canada’s TFWPs within the broader political economy and argues that global capitalism and the state interact to serve the people and economies of the Global North at the expense of migrant workers from the Global South. Cet article examine deux programmes des travailleurs étrangers temporaires (PTET) du Canada: le Programme des travailleurs agricoles saisonniers (PTAS) et le Programme concernant les aides familiaux résidants (PAFR). Cet essai examine plusieurs aspects des PTET. Premièrement, je tiens compte du contexte social et économique dans lequel ces programmes sont apparus. Deuxièmement, j’explique comment ces programmes maintiennent une hiérarchie basée sur la race et le sexe. Troisièmement, je pose le problème des relations entre les PTET et le statut de citoyen, et je formule également une critique du PTET comme solution à long terme à la pénurie de main-d’œuvre canadienne. Enfin, je discute des avantages potentiels de ces PTET et propose des solutions de rechange et des façons d’améliorer les programmes. À l’aide d’un cadre d’analyse marxiste, les PTET du Canada sont évalués globalement dans le contexte de l’économie politique et il est proposé que le capitalisme mondial et l’État interagissent au service des citoyens et des économies de l’hémisphère nord, au détriment des travailleurs migrants en provenance de l’hémisphère sud.
“Poetic” publics: Agency and rhetorics of “netroots” activism in post-earthquake L’Aquila
Authors: Pietrucci Pamela 
Published: August 2021

In this essay, I analyze the rise of post-earthquake activism in L’Aquila as an exemplification of counterpublics’ transformation into social movements endowed with “poetic” agency. Engendering “poetic agency,” for a counterpublic and for a social movement alike, denotes being able to bring forth change in the world and being able to generate change in a creative, “poetic” way. In this sense, poetic assumes a connotation that opposes the Habermasian perspective of a public sphere in which only a rational-critical discourse can be engendered as check on the State. In the case of L’Aquila, I contend that the post-earthquake social movements’ capability of effecting change in public life through poiesis has been enhanced by the possibilities of the Web 2.0 and by the activists’ acknowledgement of new ways of political participation in a world of spectacularized politics. In this instance, strategies such as the exploitation of alternative “public screens” on the web and the use of “minor rhetorics” to contrast the mainstream media portrayal of the post-disaster situation worked together in a creative and spontaneous effort to improve the condition of the people living in the area affected by the quake.

Introducción: Los espaciadores de cemento con antibiótico pueden ser fijos o articulados y se logra un resultado similar con ambos para erradicar una infección. Nuestro objetivo fue comparar el rango de movilidad articular y los resultados funcionales después del reimplante.
Materiales y Métodos: Estudio de cohorte retrospectiva de pacientes sometidos a una revisión de la prótesis de rodilla por infección, en dos tiempos quirúrgicos. Se analizó la funcionalidad según el Knee Society Score (KSS) al año de la cirugía y se registró el rango de movilidad a los 45 días. Se registraron el grado de defecto óseo, dolor, satisfacción, las complicaciones y la recidiva de la infección.
Resultados: Se incluyeron 103 pacientes (40 con espaciador articulado, 63 con espaciador fijo). El grupo con espaciador articulado tuvo una mediana 2,5° mayor en la movilidad final (102,5; RIC 95-110 vs. 100;RIC 90-105, p 0,01). Según el KSS funcional y el KSS de rodilla, no hubo diferencias entre ambos grupos. No hubo diferencias en el grado de satisfacción, dolor y el tiempo hasta el reimplante. Las complicaciones fueron similares en ambos grupos, con una tasa de reinfección sin diferencias estadísticamente significativas.
Conclusión: Los espaciadores articulados proporcionaron un beneficio en el rango de movilidad después del reimplante de la prótesis.

Authors: Castro Solange De , Rossetto Elisabeth 
Published: August 2021

Resumo: A pandemia originada pela COVID-19 novo agente do Coronavírus (SARS-CoV-2), desencadeou em 2020 alterações no modo de realização das atividades escolares. Considerando as particularidades dessa realidade, o objetivo deste estudo é discutir a implementação do ensino remoto no Estado do Paraná. Trata-se de um estudo teórico e documental amparando-se no Ofício 040/2020 DEDUC/SEED que rege o planejamento das avaliações escolares. Os resultados apontam que com a implementação do ensino remoto tem-se agravado a desigualdade social, pois nem todos têm acesso aos meios utilizados, e o papel do professor adquiriu outro contorno em que o processo ensino aprendizagem tem se dado de maneira fragmentada e isolada, apresentando-se maior valorização dos aspectos quantitativos e minimizando a importância do conhecimento.Palavras-chave: Ensino Remoto.
