Paradox of voting: peril of the vetoing to the perpetual peace
Authors: Ibrahimov Vugar
Published: April 2023

The permanent members of the Security Council of the United Nations possess veto power which was vested to them by the Charter of the United Nations to maintain global peace and security. As many, as well as recent events (Russia’s illegal aggression towards Ukraine in 2022) exhibit, in certain circumstances casting veto power, poses some perils to the global peace, per se, and they are twofold. First, all permanent members can exercise this power, according to their will, to block any resolution of the Security Council, including those that deplore their own illegal and illegit actions. The second challenge is the amendment of the UN Charter. The present wording of the UN Charter makes amending the Charter paradoxically onerous, if not impossible (by giving huge power to the permanent members again). Consequently, this situation has long triggered and urged politicians and legal scholars to explore possible solutions. This article will humbly contemplate the issue and explore the suggestions for the reinvigoration of the existing instruments to resolve the current legal and political quagmire.
The future of defence rights in the light of the mcdonaldisation of criminal justice systems
Authors: Sutton Pierre-Louie
Published: April 2023

Alongside the process of globalisation, from which no state can escape today, there appears to be an underlying “Americanisation of the world”, which is reflected essentially in the worldwide export of American industry and capital, but also of ideas, customs, and social habits. Among these habits, the American sociologist George Ritzer has highlighted the spread of fast-food chains which, according to him, is less a sign of the generalisation of a way of consuming than the implementation of a way of thinking. Indeed, Ritzer observed that contemporary societies have gradually abandoned the traditional way of reasoning in favour of more rational ways of thinking, similar to fast food chains, which rely on efficiency, calculability, predictability and the use of new technologies. Described as “McDonaldisation”, in reference to the famous multinational fast-food corporation, this phenomenon of rationalisation is affecting “more and more sectors of American society as well as the rest of the world” due to cultural homogenisation resulting itself from globalisation. Indeed, the American justice system as well as “the rest of the world”, such as many European legal systems, are also concerned by it, particularly regarding their criminal procedures, which are increasingly under the influence of this process of “McDonaldisation”. The relatively recent use of guilty pleas for individuals and legal persons, the use of sentencing guidelines and the increase in predictive justice in criminal matters reflect the key aspects of “McDonaldisation” mentioned above, namely efficiency, calculability, predictability, and the use of new technologies. However, this streamlining trend harms the defence rights placed at the heart of criminal procedures in general, such as the right to a fair trial, the right to an independent and impartial tribunal, the presumption of innocence and the individualisation of punishment.This paper therefore examines the future of these fundamental rights in the light of the “McDonaldisation” of criminal justice in America and in various European States and focus on the new principles that now guide it.

To ensure the cleaning and sanitization of the root canal system during mechanical and chemical preparation, potentiation by physical agents is important. The literature shows that an average of 35% to 53% of the canal walls remain untouched, exposing the limitations of mechanical instruments and emphasizing the importance of chemical substances for chemical-surgical preparation and tubular decontamination. The aim of the present study was to analyze the disinfecting capacity of three chemical substances used in endodontic treatment on an aggressive species of microorganism. The methodology applied was an experimental laboratory study to compare the antimicrobial potential of 1% Sodium Hypochlorite, 2% Chlorhexidine and 17% Silver Nanoparticle, used in endodontics against the pathogen E. Faecalis, selected from the microorganism bank of the laboratory of Molecular and Clinical Microbiology of the Graduate Program in Health Sciences at and whose storage and use was previously authorized by the Research Ethics Committee of the São Francisco University. After collecting data, it was possible to check the results and conclude that the 2% chlorhexidine solution presented the best results in terms of antimicrobial efficacy compared to the 1% sodium hypochlorite solution, followed by the silver nanoparticles at 17%. The latter was not able to form a growth inhibition halo against E.faecalis in vitro.

Introduction: Neonatal sepsis is a global burden on the health and wellbeing of the neonates. It mounts too many neonatal mortality and morbidity. However, rational use of antimicrobial therapy and aggressive supportive management has modified the outcome over the past few decades. A good knowledge of locally prevalent microbes and antibiotics sensitivity pattern help in formulating antibiotics regimen. Methodology: This study is a retrospective analysis of prevalent microorganisms isolated from various culture samples collected from neonates aged 0 - 90 days, suspected to have early or late onset neonatal sepsis. All the neonates were admitted to Neonatal intensive care unit (NICU) of Latifa Women and Children Hospital (LWCH) over an 11 year period (from January 2011 till December 2021). Descriptive analyses were used with results presented as proportions. Data were analyzed using Microsoft excel 2016 and online calculators. Results: A total of 4849 microbial culture positive isolates were identified from our NICU. These isolates included samples taken from, blood, cerebrospinal fluid, endotracheal aspirates, throat/nasopharynx, urine, rectal, stool, eyes and superficial cultures. Gram-negative bacteria were isolated in 56.3% (n= 2730). Gram positive bacteria accounted for 43.7% (n=2119) of isolates. Most common isolated bacterial species were Klebsiella pneumoniae (15.7%), Coagulase Negative Staphylococcus (CONS) (14.6%), Stenotrophomonas maltophilia (11.5%) and Pseudomonas aeruginosa (11.1%). Among the multidrug resistant organism (MDRO), Extended spectrum beta lactamase (ESBL) K. pneumoniae (n=208, 4.3%) and Methicillin resistant staphylococcus aureus (MRSA) (n=145, 3%) are the predominant strain. Over the study period, there is a significant reduction in both gram positive and gram negative bacterias (n=1055 in 2011 to 226 in 2021). Discussion/conclusion: The need of the hour is implementation of strict infection control measures and rationalized use of broad-spectrum antibiotics and continuous surveillance of emergence of MDROs. Regular tracking of the microbiological prevalence pattern kept us updated regarding prevailing organisms and emergence of MDROs. Our NICU antimicrobial policy modified in accordance with the surveillance data.
Pressure ulcers in older adults in a permanent geriatric stay
Authors: Cantu Sanchez Claudia Marcela
Published: April 2023

We call human aging a gradual and adaptive process of a biological, psychological and social type, produced as a consequence of genetically programmed changes, history, lifestyles, environment and social conditions to which the person was exposed. On the other hand, old age is a stage of life whose beginning is established by society, which is why the United Nations Organization agreed that, in developing countries, people aged 60 and over are classified as older adults. In institutionalized older adults, the prevalence of pressure ulcers is a worrying issue in the development of nursing care plans. Prolonged bedridden, reduced mobility, malnutrition, physiological alterations, incontinence, among others, are causes that can cause pressure ulcers, as well as aspects related to current strategies and practices for their prevention in patients at a social health center. This is considered important because during aging structural and functional changes occur in different organs and systems. For this reason, as health professionals, we must know the normal morphological and functional changes of physiological aging, and thus guide the elderly to adapt and improve their lifestyle.
On the thermoelectric alloy SixGe1-x
Authors: I NakhutsriShvili , G Bokuchava , K Barbakadze
Published: April 2023

The temperature dependences of the electronic quality factor and universal electrical conductivity of the n-type SixGe1-x alloy, as well as the dependence of the Seebeck coefficient on the specific and universal electrical conductivities are studied. Based on the measured thermoelectric parameters (Seebeck and thermal conductivity coefficients, specific resistance) the values of thermoelectric efficiency Z are calculated. The temperature dependences of universal electrical conductivity shows that the experimental points form almost a single set. This is due to the fact that changes of σ and B_E compensate each other. And, in general, the electronic quality factor BE performs scaling of thermoelectric quantities. The temperature dependences of thermoelectric efficiency shown that all SixGe1-x samples have a fairly high efficiency (≥7∙10-4 grad-1), the maximum of which is reached at about 700℃. The studied alloy were used as an element of a monolithic thermoelectric module.

Published: April 2023

The article presents the results of morphological and anatomical analysis of the Cystoseira sensu lato taxa in the flora of Ukraine, taking into account modern views on the nomenclature of the genus. Earlier, based on the morphological and molecular phylogenetic analysis, it was shown that along the Ukrainian shores the polyphyletic genus Cystoseira s. l. is represented by three taxa (Ericaria crinita f. bosphorica (Sauvageau) S.S.Sadogurska, J.Neiva et A.Israel., Gongolaria barbata (Stackhouse) Kuntze f. barbata and Gongolaria barbata f. repens (A.D.Zinova & Kalugina) S.S.Sadogurska). As the result of the present study, for these taxa, a set of morphological features of vegetative and generative organs was analysed (general thallus appearance, structure of the apex and branches, presence/absence of appendages, aerocysts, shape and size of receptacles, presence/absence of iridescence, conceptacles, shape and structure of gametangia), as well as an analysis of the anatomical structure of the thallus (cortex and meristoderm cells on a cross section) was carried out. The analysis showed that these taxa have a wide range of morphological variability, which makes their identification difficult. At the same time, some characteristics are diagnostic and allow reliably distinguish and identify the studied taxa of the genus Cystoseira s. l. Based on the analysis, we provided a description of the main morphological and anatomical c haracteristics of the taxa and proposed identification keys for taxa of the genus Cystoseira s. l. of the flora of Ukraine. The results of the study of morphological features and the range of macroalgae morphological variability are important for further taxonomic studies, as well as clarification of keys for their identification.

The paper considers species and taxonomic composition of phytoplankton and algal mats in ponds of Hostomel urban settlement under effect of main abiotic factors. The research was carried out in May 2021. The ponds under study are shallow and the photic zone occupies the entire water column. The dissolved oxygen content was high. According to nutrient content the ponds are eutrophic. Planktonic algal communities were marked by high diversity. The identified algae referred to 8 phyla, 13 classes, 29 orders, 49 families, 87 genera and 134 species, represented by 136 infraspecific taxa. The floristic diversity at the phylum level was mainly formed by Chlorophyta, Bacillariophyta and Cyanobacteria, at the class level – Chlorophyceae, Bacillariophyceae and Cyanophyceae, at the order level – Sphaeropleales, Euglenida, Chloreallales and Bacillariales, at the family level – Scenedesmaceae, Euglenidae, Bacillariaceae, Selenastraceae and Chlorellaceae, at the genus level – Desmodesmus, Nitzchia, Monoraphidium, Trachelomonas and Euglena. According to biotopic preference planktonic and planktonic-benthic forms prevailed. In Pond ІІІ, floating algal mats were observed. They appeared when benthic communities composed of Charophyta, Bacillariophyta, Chlorophyta and Euglenozoa rose to the water surface. Their cell count reached 28168–368149 thousand cells∙m–2, biomass – 21–362 g ∙ m–2. Algal mats caused a local negative effect due to water column shadowing. High diversity of algal communities makes it possible for pond ecosystems to function even under human impact.

A Moreai krónika keletkezése és szerkezete

Published: April 2023

ABSZTRAKT

A tanulmány a Moreai Krónika (Τὸ Χρονικὸν τοῦ Μορέως) keletkezését, az írói szándékokat és a mű szerkezetét tárgyalja. A Krónika két legkorábbi görög kéziratának befejezése eltér egymástól: az egyik időrendi sorrendben folytatja a peloponnésosi frankok történetét, a másik egy jelentősen korábbi (?), oda nem illő, csaknem 400 soros legendával végződik Sir Geoffroy de Bruyères lovagról – ezt a történetet a másik kézirat több ezer sorral előbb említi. A verses mű átfogó elemzése, illetve e részlet jelentősége és helye alapján feltételezhető, hogy a Krónika – az ókori eposzokhoz hasonlóan – „énekekből” állhatott, azaz olyan kisebb egységekből szerkesztették össze, amelyeket önállóan adtak elő. A tanulmány első fele részletesen vizsgálja a Krónika felépítését, és feltárja, mi tartja össze az egyes énekeket, és milyen célból szerkesztették őket össze szerves egésszé. Ezután a szerkezethez nem illeszkedő, fent említett egység kérdéseit elemzi: a részlet ugyanis több népmesei motívumot is tartalmaz, mindemellett pedig párhuzamokat mutat a keresztes témájú chanson de geste-ek (keresztes-ciklus) antihőseinek történeteivel. Bemutatja, milyen kapcsolat állhat fenn a Krónika és az ófrancia vitézi énekek között, illetve hogyan hatott a frank irodalmi és kulturális hagyomány a műre. A kutatás során elemzett fontosabb részleteket a szerző a tanulmány függelékében saját irodalmi fordításában közli.
Motivation, anxiety and classroom interaction in EMI
Authors: Kopinska Marta , Fernández-Costales Alberto
Published: April 2023

This article reports on empirical research examining the motivation and anxiety of 31 undergraduate students enrolled in English medium instruction (EMI) in two Spanish universities. Due to the scant literature on this topic in EMI, the article is intended to fill a research gap by analysing the interplay between classroom interaction, motivation and anxiety. The study aims to reach a better understanding of the driving forces to engage in English-taught programmes at tertiary level and assessing the extent to which motivation and anxiety affect such engagement. The investigation presents the results of an exploratory study screening students enrolled in the first and second years of several degrees –chemistry, computer science, electrical and mechanical engineering, and history. It took a qualitative approach, using focus groups to collect the data. The findings of the study underline the importance of students’ vision as speakers of English interacting fluently in all spheres of their future lives. The positive learning experience in EMI courses is backed by a general anxiety-free atmosphere, fostering student motivation and their engagement in classroom interaction.

Authors:   Central Aerohydrodynamic Institute named after N.Е. Zhukovsky, Kornilov Gleb
Published: April 2023

The use of thermal non-destructive testing of products made of polymer composite materials for impact damage is one of the promising directions. The paper presents a mobile monitoring approach that provides damage detection at low impact values. A feature of the developed method of impact damage detection is a comprehensive consideration of the presence of a coating on the surface of composite material, the type of a source of thermal loading, the technical excellence of the thermal imager and the capabilities of the temperature imaging software. In the post-processing of thermal imaging data, the method used monoframe-processing technology, which included a set of operations: visualization of imaging data in a monotone palette, contrast enhancement of the thermal image and sub-framing – narrowing the area of analysis of the original thermal image, with a scanning search.

Connection between pilot fuel flow and pressure pulsations in dry low emission combustor is established on base of experimental data. Determining quantitative criteria of homogeneous or diffusion flame is formulated. The criteria give chance to evaluate quality of mixing fuel and air and combustion without emission measuring. The root-mean-square deviation of the dependence of the distribution of the air-fuel mixture concentration field over the combustion chamber cross section on the correlation coefficient between the pilot fuel ratio and the double amplitude of pressure pulsations in the flame tubes for a homogeneous (technically mixed air-fuel mixture) circuit was approximated based on the data obtained. The results obtained make it possible to significantly improve the quality of emission prediction by refining the semi-empirical mathematical model of the nitrogen oxides' generation, built on the basis of the Zeldovich thermal mechanism for low-emission operating modes of dry low emission combustor of the gas turbine engines. The account of heterogeneity of the process in the flame tubes makes it possible to move from the assumption of the geometric and gas-dynamic identity of the flame tubes to their actual heterogeneity. This conclusion allows refining the model. The developed mathematical model can be used as a virtual emission sensor in advanced tracking control systems of gas turbine engines.
A METHOD FOR DETERMINING THE CHARACTERISTICS OF THE VIBRATION STRENGTH OF A STRUCTURE DURING HIGH-SPEED TRACK TESTS OF AIRCRAFT EQUIPMENT

Achieving the speed limits by ballistic aircraft is a priority, relevant and new technical challenge for the present. Track tests of such products are one of the final stages, confirming their practical performance and efficiency. Testing of products of aviation and rocket technology at the "Rocket Rail Track 3500" FKP "GkNIPAS" named after L.K. Safronov allow to accurately simulate the real conditions in which they are operated. The experimental setup includes a two-rail track, made on a special base, which excludes the unacceptable deflection of the R65 rail, with its fixing every 0.5 m by a special embedment design. The rail track has an acceleration section with an angle of attack of 2º and a length of 2500 m and a deceleration section. The test object is placed on the missile track carriage in such a way as to exclude the impact on it of shock waves reflected from the elements of the carriage and relief. Solid propellant rocket engines are installed on the carriage, which provide the necessary thrust. The sliding bearings of the rocket carriage cover the head of the rails. The thrust of the starting rocket engines provides the necessary acceleration to achieve the maximum values of the required test speed. Track high-speed tests of special equipment objects are accompanied by intense vibration and shock loading of the structure. As the speed of products increases above 600 m/s, as tests have shown, the amplitude of elastic oscillations of the structure can reach the maximum values permissible from the strength conditions. Experimental and theoretical study of vibration and shock effects on the structure of a track carriage with test objects under the conditions of an existing rail track is an urgent task for practice.

The article describes the results of tests of standard woven and unidirectional polymer composite specimens tested for interlayer shear by the short beam method. Each group of tested specimens has a different thickness, which varies with a certain step. The key features of these tests are described and a comparative analysis of the results obtained is performed. To account for the influence of external factors, tests were conducted under different conditions (standard laboratory conditions, at reduced temperature and moisture-saturated specimens at elevated temperature). On the basis of the obtained data and the performed analysis the diagrams of dependence of the ultimate strength at interlayer shear from the thickness of the specimen were plotted, the diagrams of the range of the obtained values were plotted, the statistical significance was estimated by Student's test and the effect of the cross-sectional dimensions (in this case the thickness) of the standard specimen on the ultimate strength at interlayer shear was determined. To obtain more extensive and reliable data on this problem it is necessary to increase the number of specimens in each of the groups, and conduct repeated tests. The results are recommended for use in tests to determine the interlayer shear strength by the short beam method.

Due to the introduction of a new standard limiting the emission of non-volatile solid particles in the exhaust gases of a gas turbine engine, the promlem of analyzing the formation and burnout of particulate matter inside the combustion chamber becomes important in order to develop measures to reduce it. The results of three-dimensional numerical simulation of the formation of dispersed particles using the phenomenological Lindstedt – Moss model in a diffusion flame of pre-evaporated kerosene presented. Kinetic mechanisms of n-decane and aromatic hydrocarbons mixture were used to simulate kerosene combustion with flamelet model. It is shown, that taking into account the content of aromatic hydrocarbons can significantly improve the quality of modeling of dispersed particles. The best correspondence of the calculated and experimental data is shown for the kinetic mechanism of n-decane and methylbenzene. Based on three-dimensional numerical simulation of combustion process of a homogeneous mixture of pre-evaporated kerosene and air, the model was adjusted to simulate the formation of dispersed particles at high pressures corresponding to the full-scale parameters of an aviation gas turbine engine. An empirical formula for accounting for the effect of working pressure on the formation of dispersed particles is proposed.

Published: April 2023

In oceans today, there is much concern about the effects of microplastics (MPs) and other emerging contaminants (ECs). Here, the authors investigated the combinatory effects of the MPs poly(vinyl chloride) (PVC) and acrylates/C10–30 alkyl acrylates cross-polymer (AC) (which are commonly found in face wash), together with 2-phenoxyethanol (an EC commonly used in soaps). The model photosynthetic unicellular alga Chlamydomonas reinhardtii was used to study the potential of these pollutants to initiate algal blooms. It was shown that AC alone resulted in a greater decline in algal biomass as compared with PVC in the short term (14 days). While algal cultures exposed to PVC registered the highest increase in concentrations of the chlorophyll a pigment, it was the combinatory effects of each MP and 2-phenoxyethanol that were the most pronounced in terms of the large increase in algal biomass and the formation of extracellular polymeric substances. Proliferative growths of C. reinhardtii after prolonged exposure to AC–EC contaminants show potential for initiating algal blooms in aquatic environments. Hence, AC should be considered for regulation of waste water removal into water bodies, and other combinations of MPs and ECs should also be investigated.
“[She] was very eager for men and hated living alone”: Supernatural Women who Pose a Threat to Men in Icelandic Legends
Authors: Jónsdóttir Dagrún Ósk
Published: April 2023

This article examines the ways in which various supernatural women who pose threats to men are presented in the Icelandic folk legend collections from the late nineteenth and early twentieth centuries. It focuses on narratives dealing with both female trolls and “hidden” women (elves) that appear to present a danger to male hegemony because of how they challenge the ruling ideology of the time with regard to femininity and sexuality. As the article demonstrates, in most cases, the legends show these threats being mitigated. The article therefore argues that these legends can be read as reinforcing the idea that women should not be tempted to violate hegemonic norms regarding femininity. 
Negotiating Tradition Archives in a Community Setting: Sounds of Silence and the Question of Credibility
Authors: Fogel Tom , Schrire Dani
Published: April 2023

Following the digitization of archival records of ethnographic work conducted among Yemeni Jews in the early 1970s, we presented these findings to the same community at the same location, fifty years later. In this renegotiation, our interlocutors radically undermined the credibility of our archival material. We analyze the audience’s reactions and the way they reflect different ethnographic dynamics, contextualizing their critical position in the tensions between archival knowledge and lived repertoire in general, and specifically in relation to traumatic experiences of Yemenis in Israel. Finally, we discuss how the suspicion toward the archive is embedded in larger current discourses on “truth” and “facts” and how in this context, it can be beneficial to scrutinize tradition archives in a community setting.@font-face{font-family:"Cambria Math";panose-1:2 4 5 3 5 4 6 3 2 4;mso-font-charset:0;mso-generic-font-family:roman;mso-font-pitch:variable;mso-font-signature:3 0 0 0 1 0;}@font-face{font-family:Calibri;panose-1:2 15 5 2 2 2 4 3 2 4;mso-font-charset:0;mso-generic-font-family:swiss;mso-font-pitch:variable;mso-font-signature:-469750017 -1073732485 9 0 511 0;}@font-face{font-family:Georgia;panose-1:2 4 5 2 5 4 5 2 3 3;mso-font-charset:0;mso-generic-font-family:roman;mso-font-pitch:variable;mso-font-signature:647 0 0 0 159 0;}p.MsoNormal, li.MsoNormal, div.MsoNormal{mso-style-unhide:no;mso-style-parent:"";margin-top:0cm;margin-right:0cm;margin-bottom:8.0pt;margin-left:0cm;text-align:right;line-height:107%;mso-pagination:widow-orphan;direction:rtl;unicode-bidi:embed;font-size:11.0pt;font-family:"Calibri",sans-serif;mso-fareast-font-family:Calibri;mso-ansi-language:EN-US;mso-fareast-language:EN-US;mso-bidi-language:HE;}.MsoChpDefault{mso-style-type:export-only;mso-default-props:yes;font-size:11.0pt;mso-ansi-font-size:11.0pt;mso-bidi-font-size:11.0pt;font-family:"Calibri",sans-serif;mso-ascii-font-family:Calibri;mso-fareast-font-family:Calibri;mso-hansi-font-family:Calibri;mso-bidi-font-family:Calibri;mso-font-kerning:0pt;mso-ligatures:none;mso-ansi-language:EN-US;mso-fareast-language:EN-US;mso-bidi-language:HE;}.MsoPapDefault{mso-style-type:export-only;margin-bottom:8.0pt;text-align:right;line-height:107%;direction:rtl;unicode-bidi:embed;}div.WordSection1{page:WordSection1;}
Queer, Christian and Afrikaans: The libidinal, sexuality and religion in Kanarie and Skeef
Authors: Ncube Gibson
Published: April 2023

Religion is often viewed as incompatible with queer sexualities and genders. In the Afrikaans-speaking communities of South Africa, Calvinist doctrine and dogma have been used to marginalise and ostracise those sexual and gender identities that stray from the heteronormative scripts sanctioned by cultural and religious practices. In this article, I examine how the libidinal is central to the way in which queer and faith communities interact in Afrikaans-speaking communities in two films: Kanarie and Skeef. The two films represent different filmic genres with Kanarie a fictional feature film and Skeef being a documentary. The two films, despite their different genres, broach the difficulty of being queer and religious. At the same time, the films show that it is possible to rethink religions/faith communities. Such rethinking creates accommodative spaces within faith communities in a way in which queerness is not viewed as a deviance or an abomination. I read these Afrikaans-language films against the conceptualisation of the libidinal offered by Keguro Macharia together with the ideas of queer agency proposed by Adriaan van Klinken. This queer agency marks not just a transgression of heteronormative Christian norms but also engenders expansive ways of understanding human sexuality and gender identities.
The Performance of Top Coronavirus Vaccine Stocks during COVID-19 Pandemic: A Multifractal Analysis
Authors: ÖZDEMİR Onur
Published: April 2023

This study assesses how the coronavirus pandemic (COVID-19) affects the 5-day week multifractal properties of five vaccine stocks (i.e., Pfizer, BioNTech, Moderna, Johnson&Johnson, and AstraZeneca) using weekday index data ranging from 9 December 2019 to 6 January 2022. The main concern is to document whether the presence of herd investing and the level of market efficiency changed between pre-vaccination (i.e., 9 December 2019 - 8 December 2020) and post-vaccination (i.e., 9 December 2020 - 6 January 2022). The generalised Hurst exponents are calculated through multifractal detrended fluctuation analysis. Overall, the empirical results show multifractality for each vaccine stock during the COVID-19 outbreak. Besides, the efficiency level differs among the vaccine stocks based on multifractal properties. The results indicate that the post-vaccination period is more prone to herd investing in BioNTech and Moderna stocks. Considering the impacts of this far-reaching outbreak, the highest MLM (inefficiency) index value is also attributed to BioNTech before and after the COVID-19 vaccination process.

Authors: KARAÇOBAN Aynur , SALTIK Ömür , DEĞİRMEN Süleyman
Published: April 2023

The study aims to reveal the relationship between financial innovation in the banking sector and economic growth for Statistical Region Units Level-1 (12 regions) and Türkiye's 81 provinces. In the study, annual data from 2010 to 2021 was employed. The Arellano-Bond GMM first differences and Pooled Data approach were used as models. The coefficient of the variable measuring financial innovation in the banking industry was significant and positive for the regions and provinces. The findings suggest that the banking sector's innovative goods and services, led by technical advancements and globalisation, contribute positively to the economies of certain Turkish regions and provinces. These empirical validate Schumpeter's theory and ideas of endogenous growth.

Korkunun Yatırım Kararları Üzerindeki Etkisinin İncelenmesi ve Psikolojik Faktörler ile Yorumlanması: Türkiye Üzerine Bir Araştırma
Authors: UĞUR Ahmet , TOSUN Nergis
Published: April 2023

Bu çalışmada korkunun yatırım araçları üzerindeki etkisi davranışsal finans kapsamında incelenmiştir. Korku göstergesi olarak Türkiye Finansal Korku Endeksi hesaplanmıştır. Daha sonra yatırım araçları ile ilişkisi Zivot-Andrews (1992) Birim Kök Testi, Gregory Hansen (1996) Eşbütünleşme Testi, Toda-Yamamoto (1995) Nedensellik Analizi ile incelenmiştir. Analizler sonucunda Türkiye’de korku ve yatırım araçları arasında ilişki olduğu bulgusuna ulaşılmıştır. Duygusal ve bilişsel faktörler yatırım araç tercihlerinde etkili olmuştur. Duygusal faktörlerden kayıptan kaçınma, pişmanlıktan kaçınma ve statüko eğilimi yanlılıklarının etkisi görülmüştür. Bilişsel faktörlerden ise belirsizlikten kaçınma, sürü davranışı ve tutuculuk yanlılığı faktörlerinin etkisinin ortaya çık olduğu yorumu yapılmıştır.

Cilj ovog priručnika jest pomoći nastavnicima, učiteljima i stručnim suradnicima u školama koje pohađaju ili se očekuje da će ih pohađati djeca izbjeglice da pridonesu u procesu integracije te djece u osnovnu školu. U priručniku smo predstavili dva intervencijska programa – program koji se temelji na metodi suradničkog učenja za škole i razrede koje pohađaju djeca izbjeglice te program koji se temelji na metodi zamišljenog kontakta za škole i razrede koji se tek pripremaju za upisivanje djece izbjeglica. Oba su programa razvijena na temelju najnovijih znanstvenih spoznaja, ali i prijedloga, komentara i povratnih informacija nastavnika i stručnih suradnika škola uključenih u ovaj projekt. Stoga se nadamo da će ovaj priručnik i programi predstavljeni u njemu pomoći školama u integraciji djece izbjeglica u njihove razrede. Materijali predstavljeni u priručniku dostupni su u repozitoriju Filozofskog fakulteta te na web-stranici projekta IRCiS. Na istoj stranici može se preuzeti i elektronička verzija priručnika.
GENETIC IDENTIFICATION OF CATTLE, PIGS AND HORSES IN PRODUCTS OF ANIMAL ORIGIN
Authors: Rojas De La Cruz Yhan Carlos , Paucar Chanca Rufino , Contreras Paco Jose Luis
Published: April 2023

The identification of species in animal-origin food is highly important in both quality and food safety issues. Adulteration in food is relevant for economic, religious, legislative or public health reasons. The objective of this study focused on identifying animal species (cattle, pigs and horses) in meat products in order to determine adulteration in the sale of mortadella (MO), hot dog (HD), pressed pork crackling (CP), chorizo (CH) and ham (JA). DNA was extracted from 5 different regions of each sausage and PCR was performed using species-specific primers. The species-specific region PCR amplicon was 271, 212 and 145 bp for cattle, pig, and horse meat, respectively. H.D was the only product amplified by the bovine-specific primers. The C.P and CH were amplified by the pig primers, since both products contained meat of this species. No amplification was observed in MO, H.D and JA, despite the fact that these included pork, according to the label declared by the company. These results show the existence of adulteration in the sale of these products. In the case of equine primers, no meat product has been amplified. It is concluded that there was a possible presence of adulteration in certain products, which represents a potential risk to public health and economic losses for consumers.
DIET OF Phalacrocorax bougainvillii “GUANAY” IN NORTH CHINCHA ISLAND, PISCO-PERU. MARCH-SEPTEMBER 2019
Authors: Marcial Ramos Ronald Wilmer , Calle Apolo Rayza Isabella
Published: April 2023

In order to determine the species that make up the diet of Phalacrocorax bougainvillii, "guanay" on Chincha Norte Island from March to September 2019, 55 monthly residual boluses were collected and analyzed, covering settlement and reproduction stages. 17 prey species were recorded (15 fish, 1 cephalopod and 1 crustacean). Engraulis ringens “anchoveta” was the most abundant prey in both stages, with 95.91% of the otoliths (n=27 020), of which 68.19% correspond to adults and 31.81% to juveniles. The Levins index shows that P. bougainvillii is a specialist predator. In addition, elements not typical of the diet were found in the residual boluses, such as isopods 10.65%, lice 2.08%, ticks 0.52% and microplastics 7.01%.
