Η επίδραση του ουρσοδεοξυχολικού οξέος σε παθολογοανατομικούς δείκτες ηπατικής αναγέννησης ύστερα από ηπατεκτομή
Authors: Παπακωνσταντίνου Δημήτριος
Published: December 2021

Εισαγωγή: Η ηπατική αναγέννηση είναι μία σύνθετη διαδικασία που εμπλέκει πολλαπλούς μοριακούς μησχανισμούς που λειτουργούν σε παραλληλία. Το ουρσοδεοξυχολικό οξύ (UDCA) θεωρείται πως ασκεί προστατευτική δράση έναντι του οξειδωτικού stress και της ενζυματικής αποδόμησης της εξωκυττάριας θεμέλιας ουσίας. Ο στόχος της παρούσας μελέτης είναι να διερευνήσει την επίδραση της χορήγησης UDCA στα ιστικά επίπεδα έκφρασης κυκλοξυγενάσης 2 (COX-2), σε ένα περιβάλλον οξείας ηπατικής ανεπάρκειας έπειτα από εκτεταμένη (80%) ηπατεκτομή.Υλικό και μέθοδοι: Εικοσιτέσσερις (24) ενήλικες επίμυες τύπου Sprague-Dawley, άρρενος φύλου, χωρίσθηκαν με τυχαιοποιημένη μέθοδο σε μία πειραματική ομάδα (ομάδα UDCA) και σε μία ομάδα ελέγχου. Τα πειραματόζωα στην ομάδα UDCA (n=12) έλαβαν προθεραπέια με per os χορηγούμενο UDCA για διάστημα 14 ημερών, ενώ η ομάδα ελέγχου (n=12) έλαβε διάλυμα placebo από φυσιολογικό ορο. Όλοι οι επίμυες υπεβλήθησαν σε 80% ηπατεκτομή και 48 ώρες μετεγχειρητικά, κατά τον τερματισμό του πειράματος συλλέχθηκαν δείγματα αναγεννώμενου ηπατικού ιστού και αίματος.Αποτελέσματα: Ο μετεγχειρητικός μιτωτικός δείκτης και τα επίπεδα του Ki-67 υπήρξαν αυξημένα στην ομάδα UDCA (43±11.4 και 13.7±24.7 έναντι 31±16.7 και 7.6±5.7, στην ομάδα ελέγχου), χωρίς ωστόσο στατιστική σημαντικότητα. Προθεραπεία με UDCA οδήγησε σε στατιστικά σημαντική μείωση της έκφρασης COX-2 στο ηπατικό παρέγχυμα (p=0.028) όπως επίσης και των επιπέδων TNFa στον ορό του αίματος (37.3±10.9 pg/mL έναντι 75.4±14.4 pg/mL στην ομάδα ελέγχου, p=0.004). Το σκορ έκφρασης COX-2 στο εναπομείναν ήπαρ κατά τον τερματισμό του πειράματος εμφάνισε μη-συσχέτιση (r=0) με τα επίπεδα TNFa στην ομάδα ελέγχου, ενώ αντιθέτως στην ομάδα προθεραπείας με UDCA, η συσχέτιση μεταξύ των δύο παρατηρήθηκε αυξημένη έναντι της ομάδας ελέγχου (r=0.45).Συμπεράσματα: Η προεγχειρητική χορήγηση UDCA καταστέλλει την ιστική έκφραση COX-2 μετά από εκτεταμένη 80% ηπατεκτομή και ενισχύει την αναγεννητική απόκριση μέσω μηχανισμών ευαισθητοποίησης (preconditioning) του ηπατικού ιστού στην επίδραση κυτταροκινών και ιδίως του TNFa. Η ασθενής συσχέτιση των επιπέδων COX-2 με το αντιγόνο Ki-67 υποστηρίζουν ότι ο ρόλος της COX-2 κατά τη πρώιμη φάση της ηπατικής αναγέννησης είναι δευτερεύουσας σημασίας.

Published: December 2021

This study aimed to determine the effect of project-based learning on student learning outcomes and creative thinking skills in computer numeric control subjects at SMK KAL-1 Surabaya. This study used a quasi-experimental factorial research design with a 2-way ANOVA test technique. In this study, 66 students from class XI of the Mechanical Engineering Expertise Program were divided into experimental groups (n= 33) and a control group (n= 33). The instrument used in this research is in the form of test sheets and observations to measure the level of students creative thinking and their learning outcomes. This study found that student learning outcomes using project-based learning are significantly higher than students who taught using direct learning models in computer numeric control subjects. Furthermore, the learning outcomes of students who have a high level of creative thinking are significantly higher than those of students who have a low level of creative thinking. Moreover, there is an interaction between using learning models and creative thinking on three domains of learning outcomes (cognitive, affective, and psychomotor) in computer numeric control subjects.
Predictors of sexual function among men after myocardial infarction: a pilot study
Authors: Smith Asa B , Barton Debra L , Jackson Elizabeth A , Wittmann Daniela , Smith Jacqui , Davis Matthew
Published: December 2021

Background/Aims

Sexual dysfunction often persists among men who have had a myocardial infarction. While some cross-sectional and longitudinal research has been conducted, there are still no known modifiable targets for intervention. This pilot study aimed to model hypothesised predictive factors of higher sexual function in a cohort of men post myocardial infarction.

Methods

Using a longitudinal study design, data on sexual function, sexual fear, anxiety and depressive symptoms, and use of coping strategies were collected using the Male Sexual Function Index, Multidimensional Sexuality Questionnaire, Patient-Reported Outcomes Measurement Information System and Coping Strategy Indicator respectively. Spearman correlations were estimated to examine associations between factors at 2 weeks and 3 months following myocardial infarction. Linear regression models were conducted for sexual function while controlling for age.

Results

The data for 14 men were analysed. Sexual fear and use of problem-solving and support-seeking coping strategies were moderately correlated with sexual function at 3 months post myocardial infarction. Increased use of problem-solving and support-seeking coping strategies was associated with increased sexual function at 3 months.

Conclusions

Use of coping strategies may predict increased sexual function 3 months post myocardial infarction. However, additional studies are needed to further examine these hypothesised relationships with a larger and more diverse sample.

Abstract. Mekonen AB, Gebreegziabher BG, Wassie WA, Tsegay BA. 2019. Review: Church forests—the green spots of Ethiopian highlands. Asian J For 3: 45-53. In the central and northern highlands of Ethiopia, native vegetation is almost restricted to church forests which are the only remnant natural forest in the region. The church forests are sacred because the church is believed to be the house of God and everything in its compound is sacred and respected. However, they are under severe threats by both anthropogenic and a few natural disturbances. This review paper summarizes the role of Ethiopian church forests under the authority of Ethiopian Orthodox Tewahido Churches (EOTC) in biodiversity conservation, source of seed and seedling of native vegetation, ecological importance, ecosystem values and services to the community and to the globe in general. It also emphasizes the main challenges of these forests in terms of human disturbance and natural disturbances. It states the conservation strategies of church forests. We conclude that the EOTCs besides their religious activities played a great role in conserving the forests. However, most church forests have no clear and documented demarcations which expose them to disturbances. The churches are also cultivating fast-growing exotic species to replace native trees for the income of local residents. Finally, we recommend that the head priests should evoke and customize the conservation of sacred groves using religious thought. The government should acknowledge the church for conservation and decide to have a clear boundary for the church forest to minimize further encroachment. Forest genetic resources conservation program (in-situ), Participatory Forest Management (PFM), and rehabilitation activities have to be implemented in addition to the church conservation effort using religious thoughts, religious sanctions, and legal protection for the integrity of these remnant sacred groves. Further studies are recommended to fill the gap of sacred groves in addressing the cause of disturbance and to provide possible solutions for better conservation.
Contested social relations in the platform economy: Class structurisation and collectivisation in ride-hailing services in India
Authors: Sharma Padmini
Published: December 2021

The development of platform capitalism is restructuring social relations across the globe by altering traditional hierarchical structures, internal labour relations and their micro-political interactions. Digitally mediated platforms appear to be changing relational dynamics, contributing to a growth in individualisation among the workers. The platform economy, in general, and ride-hailing services, in particular, represent an emerging capitalistic regime that is breeding a working class with often contradictory class locations and class positions. Because the class dimension in the existing literature concerning platform workers in India has been less critically approached, this research intends to use class-based theorisation to analyse capital–labour relations in the ride-hailing service, with the aim of reflecting on the linkages between class location, class consciousness and class practices among the workers. This article highlights how the internal contradictions, combined with the external structural factors, lead to growing instrumental collectivism among the platform working class that falls short of challenging the capitalistic platform regime.

Published: December 2021

This article examines the interplay between humour, science and pandemics in culture. Asking what comic scenarios of infectious diseases look like in different media, the article focuses on comic zombiism in film, clown viruses in comics and COVID-19 jokes on the internet. What can we learn from comic zombies and the Joker – the clown prince of crime in the DC Universe – about infectious diseases? What do viral jokes about pandemics in popular communication (COVID-19 memes in particular) thatexplicitlyrefer to these pop cultural phenomena teach us about our understanding of the spread of diseases? And in what way is the spread of humour comparable to the spread of viruses? Exploring these questions, this article investigates the ways humorous interpretations of infectious diseases shape, cultivate and reinforce cultural meanings of diseases and science.
A preferred reality: Film portrayals of robots and AI in popular science fiction
Authors: Dieter Daniel G. , Gessler Elyse C.
Published: December 2021

The increasing frequency and depth of human interaction with robots and artificial intelligence (AI) prompts this research study into how media-framed portrayals of technology in popular visual media might construct social reality. Cinema serves as an important and influential form of media, and portrayals of technology in film media can influence public perceptions, specifically confirming or creating perceptions of artificial or robotic intelligence. Previous research identifies frequent portrayals of robots and AI as deceptive, aggressive monsters in films like Fritz Lang’s Metropolis and James Cameron’s The Terminator. However, as the distance between fantastic technology collapses into a new social reality where humans, AI and robots exist together, film portrayals reflect a more nuanced view and changing expectations for human-robot, human-AI interactions. The study applies framing theory and a content analysis methodology to examine filmmakers’ choices to determine robot and AI character types frequenting popular cinema. Seventeen popular films yielded 592 scenes to analyse. Findings from this quantitative content analysis revealed patterns portraying robots and AI more often as friendly, helpful companions of humans, rather than menacing or harmful to humans. Therefore, the researchers conclude that modern films primarily depict cohesive and complimentary interactions between humans and living technology, reflecting on heavy technology use and dependency. Furthermore, individuals who create these films may be illustrating scenes of a preferred reality, where AI and robots are meant to be our helpers, rather than threatening replacements in both society and industry.
‘Nothing is what it seems’: Posthumanism and late capitalism in Altered Carbon
Authors: Empey Julia A.
Published: December 2021

This article explores how class politics are interpreted within Altered Carbon, the 2018 television series based on the 2002 book of the same name by Richard K. Morgan. The series follows Takeshi Kovacs, a soldier turned rebel turned private detective, as he awakens after 250 years in stasis. Like all humans in this fictional world, Kovacs’s existence, or essence, has been compressed into a small disk known as a cortical stack. Altered Carbon does not present a liberated or democratic future, instead, it demarcates how our posthuman fantasies can mimic, or fully embody, the class politics we see today in our late-capitalist society. Altered Carbon asks us to consider where the boundaries of the self and the body truly lie and how those boundaries, or lack thereof, are open for exploitation by those with financial means. We must critique how posthumanism has, or has not, taken up class. I believe this issue is most salient when we consider how class mediates our past, present and potential futures. I analyse the cortical stack itself as a posthumanist interpretation of Cartesian dualism and how that mind and body divide is central to maintaining capitalism through the alienation of the worker. Altered Carbon asks us to consider what happens when one’s flesh and one’s identity in and of itself become transferable and never truly one’s own.
Victoria Hazan y sus grabaciones de música sefardí en NY (1942)
Authors: Kanellos Malamas Xristos
Published: December 2021

o parece ser muy habitual encontrarse con un repertorio musical turco cantado en español, incorporado en las fiestas y reuniones en los «Café Aman» de los barrios de Manhattan, Brooklyn y Bronx de Nueva York (NY) la primera mitad de siglo XX. Canciones que forman parte de la vida de las tabernas y narran historias humanas acompañando así las danzas y las comidas. Un repertorio que sigue las formas musicales de la tradición musical otomana y el sistema modal turco. Las voces cantantes, inmigrantes de distintos lugares de Asia Menor, Grecia, Armenia, Siria, traen consigo un legado musical, un repertorio que han aprendido de nacimiento, como parte de su cultura y lo trasladan a los barrios de NY creando, de esa manera, el mismo ambiente cultural que vivían en las tabernas de Estambul y Esmirna por la misma necesidad de expresión, comunicación y desahogo.
Una de las voces más brillantes que han quedado inmortalizadas, gracias a las grabaciones de Metropolitan y Kaliphon, es la de Victoria Hazan, de origen sefardí, exiliada de Esmirna, que ha dejado un legado de veintiséis canciones, entre ellas diez en ladino. En el presente trabajo nos acercamos a este repertorio para proponer un análisis que nos permite entender esas canciones a través del sistema musical del makam, así como clasificarlo en modos, entender las formas que la cantante usa en las grabaciones y finalmente poder explorar la posibilidad de reproducirlo y usarlo como cante vivo en un repertorio de concierto usando instrumentos apropiados.
A NEW PROPOSAL FOR THE CLINICAL-FUNCTIONAL CATEGORIZATION OF THE ELDERLY: VISUAL SCALE OF FRAILTY (VS-FRAILTY)

Published: December 2021

Ageing is closely associated with increasing frailty, and it continues to be defined in various different ways, complicating its practical application in the clinical context. Frailty is commonly used to predict the risk of functional decline, institutionalization or even death. Current models of frailty display significant limitations, because they are unable to encompass all the chronic conditions indicating adverse outcomes. In this article, we propose the Visual Scale of Frailty (VS-Frailty), based on the overall functionality and clinical complexity of elderly individuals. This scale emphasizes the importance of independence in basic, instrumental and advanced Activities of Daily Living (ADL), as well as taking into account the main causes of the functional decline of the elderly, such as sarcopenia syndrome, mild cognitive impairment and multiple comorbidities. The scale places the elderly into 10 categories ranging from completely independent to fully dependent. The scale provides the following advantages over other scales currently used: scope, ease of application, visual clarity, longitudinal monitoring, planning of health services, and the definition of therapeutic goals and prioritization of care. The use of VS-Frailty permits the individualization of the overall diagnosis, thus facilitating continuity of care in a systematized manner, ensuring comprehensive attention to the health of elderly individuals.

Published: December 2021

Background: Older patients’ views regarding undergoing nutrition screening within General Practice settings have not been evaluated to date. Objectives: To identify perceptions of older patients related to their experiences of having a nutrition screening process performed using the Mini Nutritional Assessment Short Form (MNA-SF®), accompanied by a clinical care pathway. Methods: Patients aged ≥75 years were invited to attend repeat screening between 6 months and one year following a first screening (n=143). Patients who were identified to be malnourished or at risk at baseline (n=44) were invited to participate in an individual interview to identify their perceptions of the MNA-SF® and the applicability of a nutrition resource kit that had been provided to them. Results: Nutritional status improved in the group identified to be malnourished/at risk at baseline (p= 0.01). Interviews indicated that the MNA-SF® process was well-received but that patients did not perceive themselves as being in need of nutrition support. Conclusion: This study demonstrates that introduction of routine nutrition screening of older patients attending General Practice can feasibly be implemented using the MNA-SF® and is acceptable to patients. It is recommended that this model of care be adopted in order to improve early identification of nutritional risk and facilitate referral to appropriate services.
BODY COMPOSITION AND POSTURAL INSTABILITY IN PEOPLE WITH IDIOPATHIC PARKINSON’S DISEASE
Authors: Diab A.S. , Hale L.A. , Skinner M.A. , Hammond-Tooke G. , Ward A.L. , Waters D.L.
Published: December 2021

Objectives: Idopathic Parkinson’s disease (PD) is the second most common neurodegenerative disorder. Our objective was to investigate the relationship between body composition and postural instability in people with PD, and age- and sex-matched controls. Design: Cross-sectional study among PD sufferers and age- and sex-matched controls. Setting: University of Otago’s Balance Clinic, School of Physiotherapy. Participants: Forty-seven people with PD and 58 age- and sex-matched controls. Measurements: Postural stability was assessed with the Sensory Organization Test, Motor Control Test, Timed Up and Go Test, and Step Test. Body composition was measured by dual energy x-ray absorptiometry (DXA). Movement Disorders Society-Unified Parkinson’s Disease Rating Scale was applied to assess PD severity. Results: Mean group differences between PD and controls for the equilibrium composite score, Timed Up and Go Tests, and Step Test were statistically significant (p<0.05); strategy and latency composite scores and body composition variables were not (p>0.05). Three PD participants were sarcopenic; 15 PD and 24 controls were obese. In PD participants, total body lean mass and age predicted latency composite scores. Disease, age, and leg fat mass predicted the Timed Up and Go Test results (p<0.05). Sex and disease predicted the equilibrium composite score (p<0.01). Conclusion: The prevalence of obesity was high and sarcopenia low in the PD group, which is a novel finding. Not surprisingly, participants with PD had reduced postural stability compared to controls. Disease status, age and sex were influential factors in the weak relationships found between postural stability and body composition. These findings may have clinical relevance for the treatment of the physical symptoms of those suffering from PD.

Published: December 2021

O artigo tem como objetivo investigar como as situações desencadeadoras de aprendizagem podem ser elaboradas na direção da apropriação de um conceito matemático. O estudo centra-se no conceito de Atividade Orientadora de Ensino (AOE) como base teórico-metodológica para a organização do ensino e nas situações desencadeadoras de aprendizagem (SDA), desenvolvidas intencionalmente por meio de jogos, histórias virtuais e situações emergentes do cotidiano em pesquisas vinculadas ao Grupo de estudos e pesquisas sobre a Atividade Pedagógica. O caminho metodológico parte do levantamento de cinquenta pesquisas que envolvem o conceito de AOE e a formação de professores ou o ensino de matemática, em trabalhos vinculados aos pesquisadores do grupo ou de seus orientandos diretos, localizados a partir dos registros dos currículos Lattes. A análise das SDA nas pesquisas revela indícios do modo geral de organização do ensino e da formação que preservam princípios da AOE como a essência do conceito e a coletividade.

Un crisol de experiencias: la extensión universitaria en dos regiones de México
Authors: Ejea Mendoza León Tomás , Molina Roldán Ahtziri
Published: December 2021

En este artículo presentamos los modos en que los programas de extensión universitaria de las Instituciones de Educación Superior de dos regiones geográficas de México se relacionan con su entorno respecto de la cuestión ambiental: la región del Estado de Chiapas y la región denominada Riviera Maya. Se puede decir que Chiapas, con su fuerte composición de población indígena comunitarista, presenta una tendencia a un “enfoque ecologista”, y que en la Riviera Maya, con su carácter de centro turístico internacional de lujo, predomina un “enfoque economicista”. Con ello, tenemos que las intervenciones y las relaciones con el entorno de las Instituciones de Educación Superior en México poseen una gran diversidad de opciones, lo cual permite afirmar que es un verdadero crisol de experiencias.
Del Yo al Nosotros

En este artículo presentamos un análisis de La Comunidad Organizada (LCO) con un propósito histórico-filosófico, a fin de esclarecer cómo el pensamiento de Hegel supo presentarse en dicha obra. Nuestro esfuerzo se centrará en el estudio del concepto de comunidad que aparece en LCO con el fin de determinar su compatibilidad con el concepto de Estado de nuestro filósofo alemán. A este fin analizaremos el modo en que Hegel es abordado por Perón en la obra, para luego desde la ambigüedad misma de esta presencia encauzar la mirada hacia la relación que, no obstante, creemos que es posible hallar entre ambos dos conceptos
Hegel en Argentina
Authors: Assalone Eduardo
Published: December 2021

El presente artículo aborda la recepción de la filosofía de Hegel en la Argentina desde una perspectiva exploratoria. Para ello ofrece un estado de la cuestión en el que se determinan las fuentes y los insumos para un estudio de ese tipo, y se propone una periodización de dicha recepción que incluye los siguientes periodos: 1) del siglo XIX hasta la Reforma Universitaria, la época de la presencia indirecta de Hegel; 2) de 1918 hasta el Primer Congreso Nacional de Filosofía de 1949, el verdadero comienzo de la recepción de Hegel; 3) de 1949 hasta 1982/83, un periodo de disputa entre las interpretaciones existencialista, marxista, teológica y peronista de Hegel; y 4) de la restauración democrática hasta la actualidad, cuando se percibe una consolidación institucional de los Estudios Hegelianos en el país. Como primeras conclusiones se destaca el carácter federal de la recepción de la filosofía hegeliana y los dos momentos principales de la institucionalización de los Estudios Hegelianos en 1931 y en 1983. El primero, en el contexto de la reacción antipositivista y la reivindicación de la filosofía alemana, y el segundo, en el marco de la estabilización de la actividad académica por la transición democrática.
La recepción de la Wissenschaft der Logik en la filosofía argentina (1932 – 1956)
Authors: Figueredo Núñez Hugo Alberto
Published: December 2021

La recepción de la Wissenschaft der Logik de G. W. F. Hegel en la filosofía argentina fue tardía y focal. A la casi nula atención al aspecto especulativo de la filosofía hegeliana durante el positivismo decimonónico, continuó un superficial interés en las primeras décadas del siglo XX que derivó en dos comentarios de la Wissenschaft der Logik: La Lógica de Hegel de M. A. Virasoro (1932) y Hegel y la dialéctica de C. Astrada (1956). Para Virasoro la obra representaba un posicionamiento lógico contrapuesto al formal con derivaciones gnoseológicas y metafísicas; para Astrada ella exponía la fundamentación del método dialéctico, el cual tenía relevancia ontológica y política. Ambos filósofos coincidieron en un interés crítico por la obra y en un privilegio exegético de la Doctrina del ser por sobre la Esencia y el Concepto. Las diferencias y las continuidades entre ambas interpretaciones conformaron la recepción inicial de la Wissenschaft der Logik en la filosofía argentina.

Marine organism is one of the riches in the ocean of Indonesia. The benefits of sea use for new products produced are widely used and have high market demand. Enzymes that have marine interests have unique properties and have good benefits for industry. This study aims to isolate the bacteria that have symbionts with Padina sp and determine the potential of the enzyme hydrolase produced by these bacteria. Isolation is done by the spread plate method. Pure isolates obtained were then tested for the potential of the enzyme hydrolase on selective media. Clear zone measurements are performed to determine which bacterial isolates are good for enzyme production. The results obtained by 6 isolates of pure bacteria, all of which include Gram negative bacteria that form bacilli. All isolates had the ability to produce different Protease, Lipase, Amylase and Cellulase enzymes. The enzymes obtained from these symbiotic bacteria are expected to be used for industrial-scale production in Indonesia. In addition, the presence of this symbiont bacteria is able to reduce the level of exploitation of Padina sp and contribute to preserving the marine ecosystem.

Xylitol (C5H12O5) is a non-carcinogenic polyalcoholic sugar. Xylitol is beneficial for diabetics because it can be metabolized without insulin. Corn cobs contain 30% xylose which can be fermented into xylitol by microorganisms. Xylitol can be produced by fermentation of xylose and few microorganisms. Meyerozyma caribbica is a yeast that has been proven to produce xylitol and inhibitor’s resistant. The aim of this research is to test the xylitol productivity by Meyerozyma caribbica InaCC Y67 using corn cobs hydrolyzate and the effect of the volume of fermentation media on xylitol productivity by Meyerozyma caribbica InaCC Y67. The method was carried out by culturing Meyerozyma caribbica InaCC Y67 as a starter on YPD media.  Fermentation using 100 mL Erlenmeyer with the variation of fermentation volume is 10 ml and 75 ml, agitation 175 rpm and 30 oC. Parameters were measured based on the dry weight of cells, xylose and xylitol. Data were analyzed using fermentation kinetics. The results of analysis showed that the higher xylitol production was found in the fermentation volume 75 ml with an efficiency value of 7,171%. The highest xylitol production was at the 48th hour with production value of 2.050 g/L. Results from research shows that Meyerozyma caribbica InaCC Y67 can produce xylitol with corn cobs hydrolyzate. The right volume of fermentation in the fermentation process can also increase the productivity of xylitol.
SİYASAL İLETİŞİMDE YENİ YÖNELİMLER NÖROSİYASET VE SİYASAL BEYNİN ÇÖZÜMLENMESİ
Authors: ÇOKLUK Nil
Published: December 2021

İktidarı ele geçirmek isteyen siyasal aktörler ile seçmenler arasındaki ilişki, siyasal iletişimin önemini gün geçtikçe artırmaktadır. İnsanın doğasının politik olması sebebiyle siyasal davranışın itici unsuru olan insan beyninin siyasal iletişimdeki rolünü incelemek gerekli hale gelmiştir. Bu durum siyasal aktörleri Aristoteles’in sosyal ve siyasal bir varlık anlamına gelen “zoon politikon” olarak tanımladığı insanın beklentilerini anlayabilmek için yeni arayışlara itmektedir. Bu arayışın sonuçlarından biri olarak siyaset bilimi ve nörobilim araştırmalarını birbirine bağlayan nörosiyaset çalışmaları ortaya çıkmıştır. Bu çalışma, siyasal liderlerin ve söylemlerinin seçmenlerin bilinçdışında yarattığı motivasyonu ve duygusal ilgiyi nörobilim teknikleriyle tespit etmeyi amaçlamaktadır. Deney yöntemiyle yapılan çalışmada nörobilim tekniklerinden elektroensefalografi, fotopletismografi ve galvanik deri tepkimesi kullanılmıştır. Çalışma Ak Parti, CHP, MHP, HDP, İYİ Parti seçmenleri ile gerçekleştirilmiştir. “İnsanların siyasal tercihleri biyometrik ve nörometrik işaretleri ile uyumludur” ve “İnsanları etkileyen siyasal unsurlar biyometrik ve nörometrik verilerden çıkarılabilir” hipotezlerini sınayan çalışmanın sonuçlarına bakıldığında bu hipotezlerin ilki kısmen doğrulanırken ikincisi tamamen doğrulanmaktadır. Çalışmanın sonuçları biyolojik ve psikolojik yapı kadar toplumsal yapının ve güncel koşulların da siyasal algı, tutum ve davranış üzerinde belirleyici olduğunu ortaya koymaktadır.
Using a Multi-Methods Approach to Investigate Disaster Preparedness of Community Libraries in the North West Province of South Africa

Published: December 2021

Disasters can occur anywhere, and no organisation is immune to disasters. Community libraries in South Africa have experienced disasters over the past years, ranging from natural disasters to human-made disasters. This research aims to investigate the disaster preparedness of community libraries in the North West Province of South Africa. A multi-methods approach that involved questionnaires, interviews, and document analysis was used. The study results revealed that although community libraries have experienced disasters, they considered them as once-off events. Consequently, disaster management was not part of the collection management policy. However, disaster management should be a key component of collection development, and it should be part and parcel of a collection management policy.

MnSb2Te4 is a candidate magnetic topological insulator exhibiting more pronounced cation intermixing than its predecessor MnBi2Te4. Investigating the cation intermixing and its possible implications on the magnetic order in MnSb2Te4 are currently hot topics in research on quantum materials for spintronics and energy-saving applications. Two single-crystal X-ray diffraction measurements of Mn1−x
Sb2+x
Te4 (x = 0.06 and x = −0.1) are presented alongside a detailed discussion of its crystal structure with a spotlight on the apparent occupancy disorder between the two cations. This disorder has been noted by other groups as well, yet never been analyzed in-depth with single-crystal X-ray diffraction. The latter is the tool of choice to receive a meaningful quantification of antisite disorder. Between the two synthesis procedures we find subtle differences in phases and/or alternation of the cation content which has implications on the magnetic order, as illustrated by bulk magnetometry. Understanding and assessing this disorder in magnetic topological insulators of the MnX2Te4 (X = Bi, Sb) type is crucial to gauge their applicability for modern spintronics. Furthermore, it opens new ways to tune the “chemical composition – physical property” relationship in these compounds, creating an alluring aspect also for fundamental science.
Time and space waveform optimization to extend the harmonic cutoff and to produce the water window single attosecond pulse
Authors: Feng Liqiang , Yuan Quan
Published: December 2021

Based on the three-step theory of high-order harmonic generation, the harmonic cutoff is very sensitive to the few-cycle laser waveform in both time and space regions. Therefore, in this paper, we propose the method to control the harmonic cutoff and to produce the water window attosecond pulse through the optimization of time and space waveform. It is found that, in the time region, by properly choosing the delay and phase of the few-cycle two-color pulse, not only the harmonic intensity is enhanced, but also the quantum path of the harmonic emission can be controlled. Further, with the introduction of the 3rd pulse (i.e., the infrared pulse or the unipolar pulse), the harmonic cutoff from the single harmonic emission peak can be extended, showing a water window harmonic plateau. In the space region, by using the positive spatial inhomogeneous effect, the harmonic cutoff from the basic two-color waveform can also be extended, which leads to a water window spectral continuum. Finally, by Fourier transformation of harmonics during the water window region, the ultrashort single 29 as pulses can be obtained.
Detection Limit (LOD) and Limit of Quantification (LOQ) Using Microscopical Methods in Asbestos Analysis
Authors: Koenig Reiner
Published: December 2021

Optical methods (light or electron microscopy) are, in most cases, the basis for measuring the asbestos concentration either in air or in materials. The individual methods are described in a variety of guidelines or standards. The definition of terms like detection limit and analytical sensitivity have led to numerous discussions, driven by the fact that in some cases concentrations that are real and not a misinterpretation are reported as below the stated detection limit. In this paper, different approaches for a detection limit (LOD) as appear in ISO, VDI, and ASTM documents are discussed and the main parameters influencing the value of the LOD are described. In addition, a concept for calculating a limit of quantification (LOQ) both for air and material analysis is described.

Authors: Compton Steven P. , Millette James R.
Published: December 2021

The results of analysis for amphibole fibers in 140 samples of finished products containing chrysotile asbestos are presented in terms of weight percent and fibers per gram. The products include friction materials, joint compounds, roof cements, floor tiles, a dryer felt, dental tapes, insulating paper (heat shields) from vintage consumer electronics, gaskets, packing, electrical components, cement boards, and resin boards. The levels of amphibole asbestos in the products ranged from approximately 0.00005% to 0.5%. Although all the levels were below 1% in terms of weight percent, there were between 540,000 and 2.7 billion amphibole fibers per gram of product. Two independent subsets of analyzed samples (friction and nonfriction) were carefully examined to determine the size ranges and average statistics for individual amphibole fibers. In both subsets, more than 98% of the fibers are less than 1 μm in width and the average width is 0.25 μm. Fiber lengths range from 0.5 μm, the minimum reportable length, to more than 24 μm with average lengths of 3.2 μm (friction) and 3.6 μm (nonfriction). Fiber aspect ratios range from 5, the minimum reported aspect ratio, to more than 122 with average aspect ratios of 15:1 (friction) and 17:1 (nonfriction).
Evolution of Approaches to Countering Hybrid Threats in the European Union’s Strategic Planning
Authors:   Institute of Europe, Russian Academy of Sciences, Bazarkina Darya
Published: December 2021

This article aims to identify the main components of the EU approach to countering hybrid threats. To achieve this goal, research questions were posed: 1) How does the theory of hybrid warfare define hybrid threats, what are its strengths and weaknesses? 2) How is the approach to combating hybrid threats regulated in the EU? 3) What changes are taking place in this approach under the influence of trends in recent years, including the crisis caused by the coronavirus pandemic? The author concludes that the “open architecture” of the hybrid war theory, the wide possibilities of interpreting the definition of hybrid threats allow us to improve practical measures and theoretical approaches to security problems. However, as economic competition and political contradictions under geopolitical rivalry deepen, the approach to countering hybrid threats is hyper politicized, being used to justify sanctions pressure, strengthening military blocs or massive psychological campaigns against a political adversary. The EU tries to develop and improve a systemic approach to ensuring security in the context of the growth of hybrid threats. However, this approach is increasingly deformed under the influence of above-mentioned hyperpoliticization. This is especially evident in the EU’s attitude towards Russia and China, which are constantly accused of creating hybrid threats. The excessive use of the rhetoric of the hybrid war theory in the EU discourse jeopardizes the security of Europe.
