Authors: Oinhas Marcos Adriano Sopeletto , Zanon Thiarla Xavier Dal-Cin
Published: December 2021

Neste artigo, busca-se responder às seguintes questões: Como as dissertações do Programa de Mestrado Profissional em Matemática em Rede Nacional (PROFMAT) de 2016 a 2020 tratam, na educação básica, a resolução de problemas de análise combinatória mediada pelas tecnologias digitais? Quais contribuições uma revisão sistemática dessas dissertações pode oferecer à pesquisa sobre essa temática no Brasil e às práticas de sala de aula? Apresenta-se uma série de análises decorrentes de uma revisão bibliográfica sistemática (Botelho, Cunha & Macedo, 2011; Romanowski & Ens, 2006) de dissertações do PROFMAT produzidas no período de 2016 a 2020. Recorreu-se a Gravina e Santarosa (1998), Onuchic (1999), Alevatto (2005) e Zanon (2019), para estudar nove produções, nas quais foram analisados principalmente as compreensões sobre análise combinatória e resolução de problemas, a presença das tecnologias digitais nas pesquisas, os aspectos metodológicos das investigações e os produtos que cada autor elaborou. O resultado das análises permitiu afirmar a existência de um conflito na compreensão do que seria a resolução de problemas, bem como a presença das tecnologias como suporte para a aplicação dos produtos elaborados.

Neste artigo se compartilham resultados de uma investigação que se propôs analisar as particularidades que se evidenciam em um curso de formação continuada, que visou contribuir para a prática do professor reflexivo e para o conhecimento didático e matemático do professor de Matemática. O estudo se apoia no conceito de Desenvolvimento Profissional Docente para professores de Matemática, e faz uso de seis objetivos de Sowder (2007) para análise dos resultados que ao fazer uso da Análise Textual Discursiva, encontrou seis categorias, as quais apontam que as formações precisam favorecer a práxis docente, e para tal, a escola precisa se responsabilizar pela formação de seus professores e tem grande potencial de ser centro da formação, proporcionando momentos de reflexão, troca de experiências, a fim de que possam repensar suas crenças e realizar planejamentos em conjunto.
How opioid prescribing policies influence primary care clinicians’ treatment decisions and conversations with patients with chronic pain
Authors: Danielson, PhD Elizabeth C. , Harle, PhD Christopher A. , Downs, MPH Sarah M. , Militello, MA Laura , Mazurenko, MD, PhD Olena
Published: December 2021

Objective: The 2016 Centers for Disease Control and Prevention guideline for prescribing opioids for chronic pain aimed to assist primary care clinicians in safely and effectively prescribing opioids for chronic noncancer pain. Individual states, payers, and health systems issued similar policies imposing various regulations around opioid prescribing for patients with chronic pain. Experts argued that healthcare organizations and clinicians may be misapplying the federal guideline and subsequent opioid prescribing policies, leading to an inadequate pain management. The objective of this study was to understand how primary care clinicians involve opioid prescribing policies in their treatment decisions and in their conversations with patients with chronic pain.Design: We conducted a secondary qualitative analysis of data from 64 unique primary care visits and 87 post-visit interviews across 20 clinicians from three healthcare systems in the Midwestern United States. Using a multistep process and thematic analysis, we systematically analyzed data excerpts addressing opioid prescribing policies.Results: Opioid prescribing policies influenced clinicians’ treatment decisions to not initiate opioids, prescribe fewer opioids overall (theme #1), and begin tapering and discontinuation of opioids (theme #2) for most patients with chronic pain. Clinical precautions, described in the opioid prescribing policies to monitor use, were directly invoked during visits for patients with chronic pain (theme #3).Conclusions: Opioid prescribing policies have multidimensional influence on clinician treatment decisions for patients with chronic pain. Our findings may inform future studies to explore mechanisms for aligning pressures around opioid prescribing, stemming from various opioid prescribing policies, with the need to deliver individualized pain care.
Influence of personality and emotional competences on academic performance: direct and indirect pathways mediated
by perceived stress
Authors: You Min , Laborde Sylvain , Samuel Vaughan Robert , Salinas Agnès
Published: December 2021

Introduction

Among the factors influencing academic performance (AP), individual differences at the trait level such as personality and emotional competences (EC) have been found to play a critical role, similarly to state variables such as perceived stress (PS).

Material and methods

The aim of this study was to clarify whether the influence of personality (Big Five) and EC on AP (general point average) is direct and/or mediated via PS. 537 undergraduate students from a French university (112 male and 425 female, Mage = 19.84 years, SDage = 1.74 years, range = 18-30 years; first year: n = 293, 55%; second year: n = 162, 30%, third year: n = 82, 15%) filled out the test battery around three weeks before the final examination.

Results

Path analysis showed that AP was directly predicted by conscientiousness (+), neuroticism (+), extraversion (–) and perceived stress (–), while perceived stress was predicted by neuroticism (+) and by intrapersonal EC (–).

Conclusions

The results illustrate the robust influence of conscientiousness on AP, while EC was not found to influence AP directly, but indirectly via its effect on PS.
The impact of appearance comments by parents,
peers and romantic partners on eating behaviour
in a sample of young women
Authors: Varnagirytė Erika , Perminas Aidas
Published: December 2021

Background

Disordered eating behaviour (DEB) is prevalent among two-thirds of women, and it is argued that it will increase over time because of the lean body cult in Western culture. However, the mechanism of DEB development is still not known precisely. One of the recently explored factors is appearance comments by significant others; however, their influence on DEB is am-biguous. The aim of this study is to investigate the relationship between eating behaviour and appearance comments by parents, peers, and romantic partners in a sample of young Lithuanian women.

Participants and procedure

Two hundred and eighty-five young females (Mage = 21.8, SD = 2.14) completed an online survey consisting of the Verbal Commentary on Physical Appearance Scale (VCOPAS) and the Eating Attitudes Test-26 (EAT-26). Demographic infor-mation and body mass index (BMI) were also taken into account.

Results

Negative comments about body shape and weight by parents, peers and romantic partners were associated with greater young women’s dieting and bulimia-specific DEB, while this type of appearance comments only by mothers and female peers was related to greater oral control. It was found that positive comments about body shape and weight by female peers were related to lower young women’s dieting, while positive comments about general appearance by mothers were associated with lower oral control. However, positive comments about body shape and weight by mothers and male peers were related to higher young women’s oral control.

Conclusions

Both negative and positive comments about physical appearance by significant others may be a risk factor for DEB develop-ing in young women. Further research should concentrate on a deeper examination of these relations, with a particular focus on positive comments about physical appearance.
Thinking clearly about dignity:
relationships between cognitive processes
underlying perceived dignity as determinants
of psychological adjustment
Authors: Pergolizzi Denise , Marimon Frederic , Monforte-Royo Cristina , Crespo Iris
Published: December 2021

Background

Public and professional views strongly equate dignity among the dying with their abilities to make decisions about medical and personal treatment and care. To make these decisions requires cognitive processes that inform our understanding of circumstances by integrating thoughts, experiences, and perceptions with prior knowledge. But patients with terminal illnesses, especially cancer, often experience problems stemming from cognitive changes and the cognitive state of uncer-tainty that can interfere with knowing what options for care are essential to targeting their sense of dignity. This paper aims to propose and test a model that defines targets for dignity-conserving care from underlying cognitive changes as antecedents to uncertainty that impact psychological adjustment of patients with advanced cancer.

Participants and procedure

This is a cross-sectional observational study using participant data from 257 patients with advanced cancer. The Patient Dignity Inventory and the Hospital Anxiety and Depression Scale were administered to patients and analyzed according to model hypotheses.

Results

Analyses used structural equational modeling to confirm model pathways. In the context of perceived dignity in advanced cancer, there was a direct pathway from patient reported problems with cognitive changes to uncertainty, that in turn had both direct and indirect effects on depression.

Conclusions

The results suggest that cognitive changes challenge perceptions of dignity and can independently be targeted as modifia-ble processes to provide dignity-conserving care.

Published: December 2021

Introduction

This study aimed to propose a categorization of body postures and to provide indexes/scores for the postural patterns.

Methods

The body posture of the 3 spinal regions in 180 asymptomatic young people, mean age: 16.1 (0.77) years, was evaluated quantitatively in the sagittal plane (cinemetry and the curvature index). The same images were presented to experts who, by way of qualitative analyses, provided the postural diagnosis of each curvature for all of the young people. Individuals with the same postural patterns were grouped together and the qualitative data were crossed with the quantitative values. Thus, scores were attributed to normal curvature, tendencies, and deviations. The one-way ANOVA test for independent samples was used to compare the patterns and the Bonferroni post-hoc test served to analyse effects between neighbouring changes. The mean difference and the 95% confidence interval were also calculated to compare the patterns. An alpha level of 5% was adopted for all analyses. The sensitivity, specificity, positive and negative likelihood ratios, and the predictive value for the suggested reference intervals were calculated to determine the diagnostic accuracy.

Results

Significantly different scores were attributed to the postural pattern curves: ≤ 0: curve inversion; 0.1–10: rectification; 10.1–11: tendency for rectification; 11.1–14: normal; 14.1–15: tendency for hyperlordosis/hyperkyphosis; > 15: hyperlordosis/hyperkyphosis. The scores presented great discriminatory capacity and diagnostic accuracy among the postural patterns.

Conclusions

This categorization could aid researchers and health professionals in evaluating postural deviations.
A Study of the Classification of Motor Imagery Signals using Machine Learning Tools
Authors: Hashmi Anam , Alam Khan Bilal , Farooq Omar
Published: December 2021

In this paper, we propose a system for the purpose of classifying Electroencephalography (EEG) signals associated with imagined movement of right hand and relaxation state using machine learning algorithm namely Random Forest Algorithm. The EEG dataset used in this research was created by the University of Tubingen, Germany. EEG signals associated with the imagined movement of right hand and relaxation state were processed using wavelet transform analysis with Daubechies orthogonal wavelet as the mother wavelet. After the wavelet transform analysis, eight features were extracted. Subsequently, a feature selection method based on Random Forest Algorithm was employed giving us the best features out of the eight proposed features. The feature selection stage was followed by classification stage in which eight different models combining the different features based on their importance were constructed. The optimum classification performance of 85.41% was achieved with the Random Forest classifier. This research shows that this system of classification of motor movements can be used in a Brain Computer Interface system (BCI) to mentally control a robotic device or an exoskeleton.

Aspectos estilísticos da tradução de "Corpo fechado", de Guimarães Rosa, para o inglês
Authors: Ferreira de Freitas Luana , Moreira de Oliveira Kamila
Published: December 2021

A tradução das obras de Guimarães Rosa teve início ainda durante a vida do autor, que, em muitos casos, ajudava seus tradutores em cartas detalhadas com sugestões e discussões sobre seu processo criativo. Nos Estados Unidos, em particular, a tradução de Rosa para o inglês acontece no contexto da aproximação dos Estados Unidos com a América do Sul entre as décadas de 1940 e 60, embora os efeitos desta iniciativa de tradução de obras latino-americanas não atinjam o Brasil com tanta força (BARBOSA, 1994; LEVINE, 2006; KRAUSE, 2010). Neste artigo, busca-se analisar como as escolhas da tradutora Harriet de Onís podem ter influenciado a recepção da obra de Guimarães Rosa em inglês. Por meio do cotejo do conto “Corpo fechado” (Sagarana, 1946) e sua tradução, “Bulletproof” (Sagarana, 1966), concluiu-se que de Onís tende a domesticar (VENUTI, 1995) o texto de Rosa, naturalizando seu estilo não-convencional e, portanto, negando aos leitores o acesso ao seu projeto estético. Sugerimos, por fim, ser possível que um novo projeto tradutório para Rosa receba mais atenção do público falante de língua inglesa do que a tentativa anterior, ao tornar o texto desafiador para o leitor, sem negar a identidade do texto de partida.
Concepções de gramática no caderno Pontos de Vista da Olimpíada de Língua Portuguesa Escrevendo o Futuro: atividades com gramática normativa e internalizada
Authors: Lima Evanielle Freire , Neves Herbertt
Published: December 2021

Toda proposta de trabalho descritivo ou escolar com os conhecimentos gramaticais reflete determinadas concepções de gramática e perspectivas didático-metodológicas diversas. Sendo assim, nesta pesquisa, com atenção específica a algumas dessas concepções, buscamos analisar as orientações de gramática normativa e internalizada no caderno Pontos de Vista, material orientador para o trabalho com o gênero Artigo de Opinião da Olimpíada de Língua Portuguesa Escrevendo o Futuro. Sobre as concepções de gramática, este trabalho fundamenta-se das contribuições propostas por Travaglia (2009), Franchi (1991; 2006), Neves (2005) e Possenti (1996). Sobre o ensino de gramática na escola, apoiamo-nos nos estudos de Antunes (2007), Faraco (2006) e Mendonça (2006). Nosso trabalho caracteriza-se pela adoção do método indutivo, de abordagem quanti-qualitativa e descritiva, com procedimento técnico de análise documental, pelo estudo dos cadernos do professor da Opinião da Olimpíada de Língua Portuguesa. Após as análises, verificamos que as concepções de gramática normativa e internalizada presentes nas orientações para o professor possibilitam um trabalho contextualizado com a gramática nas escolas, voltado a práticas efetivas de leitura e escrita.

Este estudo apresenta uma revisão bibliográfica sobre o pronome pessoal no pensamento de Saussure, Jakobson, Benveniste e Bello, buscando estabelecer relações de aproximação e distanciamento entre eles. Discute também a visão dos referidos autores e a apresentada pela gramática tradicional sobre o tema, especificamente a de língua castelhana. Conclui que as elaborações sobre o pronome de Jakobson, Benveniste e Bello dialogam entre si, distanciando-se da proposta de Saussure e da gramática espanhola tradicional.
THE "KEATING EFFECT" OU DE LA LITTERATURE COMME THAUMATURGIE
Authors: Kerlan Alain , Naouar Oussama
Published: December 2021

Através de uma analise da obra cinematográfica de Peter Weir, inspirada no romance de N.H. Kleinbau, este artigo se propõe a refletir - além do estranho pseudo-romantismo do filme - sobre as figuras do literário e de uma “taumaturgia” da função de professor de literatura. Elaborando uma reflexão analógica em torno da lenda do flautista de Hamelin, os autores nos levam a repensar fundamentalmente a questão da literatura e da filosofia americanas no que elas carregam de aspiração poética e democrática marcada pelo perfeccionismo moral.
ASPECTOS DO NEOBARROCO EM ZAMA DE ANTONIO DI BENEDETTO (1956): REFLEXOS DA IDENTIDADE LATINO-AMERICANA
Authors: Martins Livânia Régia , Rodrigues Juan Pablo Martin
Published: December 2021

Este trabalho pretende explorar a obra Zama de Antonio Di Benedetto (1956) para tecer relações aos aspectos neobarrocos presentes na construção da narrativa, especificamente, com o recorte vislumbrado ao protagonista e narrador Zama, ou “el enérgico doutor don Diego de Zama”, como prefere ser reconhecido. Para construir as reflexões sobre o neobarroco, as contribuições de Sarduy (2011) ao tratar questões como a repetição do fracasso e jogo de oposição estão presentes na construção do personagem. Calabrese (1999), será importante para pensar as imagens desenvolvidas pelos fluxos de consciência do personagem quem envolvem nós e labirintos. Além dos teóricos que abordam a questão do neobarroco, Deleuze (1997) contribuirá com sua reflexão do delírio da literatura como devir que Calabrese (1999) em outras palavras, relaciona à excentricidade encontrada na obra neobarroca. Atrelada ao contexto da América Latina, a proposta deste trabalho é refletir sobre as características neobarrocas, como parte das problemáticas herdadas de condições simbólicas do processo histórico e sociocultural, que envolve a colonização, diante da identidade problemática latino-americana ostentada através do protagonista de Di Benedetto (1956).
ESCARAFUNCHANDO QUIXOTE: Indícios de sua biblioteca
Authors: Farias Pedro Américo
Published: December 2021

O presente ensaio tem por objetivo contribuir com um dos caminhos de releitura (são inúmeros) do Dom Quixote de la Mancha. O foco recai sobre a leitura dos chamados “livros de cavalarias”, que o enfeitiçaram, enquanto leitor voraz do gênero, ao ponto de o levarem à loucura. Mas não se trata de uma avaliação do personagem Quixote, sob efeito de referida leitura, pois, com certeza, há muitas avaliações referentes ao caso. O interesse está na busca de compreensão da importância dessa literatura cavaleiresca, sob o aspecto da sua influência na mente dos leitores, especialmente daqueles que teriam um importante papel no processo de colonização e ocupação das Américas. O teor ideológico dessa literatura justifica a violência contra os gentios (mouros, indígenas), sob bênçãos dos reis e papas, ao mesmo tempo em que, para atrair adesões e mão de obra para as conquistas, estimulava a ilusão sobre a existência de ilhas misteriosas, minas de ouro e prata e outros mitos paradisíacos. Quanto ao leitor Quixote, este seria a tradução, por paródia, do mundo cavaleiresco, pelo gênio de Miguel de Cervantes. Uma autora e dois autores foram fundamentais na elaboração deste trabalho: Jerusa Pires Ferreira, Irving Leonard e Martín de Riquer.
Sobre a tradutibilidade da forma de escuta nas artes verbais
Authors: Simões Hugo
Published: December 2021

A escuta está intimamente relacionada ao fazer tradutório. Este artigo investiga essa relação, trilhando um caminho que vai da arqueoacústica até a ideia de performance proposta por Paul Zumthor, e tem como grandes interlocutores pensadores ameríndios e estudos etnográficos recentes. A ideia de forma aqui proposta se relaciona a intelectuais da então chamada “etnopoética”, bem como de autores que refletiram sobre poesia após a Shoah, como Paul Celan. Quanto aos efeitos da escuta sobre a relação tradutória, faz-se uma retomada das ideias benjaminianas de magia e memória, além de uma releitura de seu Die Aufgabe des Übersetzers (“A tarefa do tradutor”). Poética, magia e performance são pensadas por meio da chave da escuta, a qual, ao final, aproxima a tradução à ideia de sotaque.
A mente e a evolução cultural humana: suas implicações para a teoria da ficção
Authors: Chagas Pedro Dolabela
Published: December 2021

Discussão das funções que fomentaram a evolução da ficção como prática cultural, observando-se como o seu processamento cognitivo permitiu que ela se estabilizasse como hábito individual e coletivo. Argumenta-se que os dois pontos se entrelaçam: a sinergia entre funções de grande apelo coletivo e um processamento cognitivo acessível teria favorecido a popularidade e o sucesso histórico da ficção. Quanto ao primeiro ponto, sugere-se que o seu surgimento e estabilização como prática social foi motivado pela sua disposição como affordance cultural de função homeostática, nos níveis individual e coletivo. Quanto ao segundo, discute-se a sugestão da psicologia experimental de que a leitura do texto ficcional não demanda quaisquer capacidades cognitivas excepcionais: a ficção se adapta às nossas predisposições mentais, e não o contrário, i.e. a sua leitura não pressupõe capacidades mentais desenvolvidas especialmente para ela. Defende-se que esses dois argumentos convergem na explicação das origens e do sucesso evolutivo e histórico da ficção, aqui definida não apenas como um atributo de certas produções humanas ou um conjunto de produções dotadas de características comuns, mas como uma prática cultural tradicionalizada.

Published: December 2021

Структура фитопланктона является наиболее репрезентативным индикатором состояния водных экосистем, и, достаточно широко, используется в системе биомониторинга. В данной статье дается оценка качеству воды по структурным показателям фитопланктона. Анализ флористического состава альгофлоры водохранилища Капшагай выявил, что видовое разнообразие альгофлоры в них определяют диатомовые, зеленые, синезеленые, золотистые и пирофитовые водоросли, составляющие 54 вида. Наибольшим числом видов характеризовались диатомовые и зеленые водоросли. По индексу доминирования Симпсона, для фитопланктона водохранилища характерно лидирование диатомовых и синезеленых водорослей. Проведенная оценка качества воды с использованием индикаторных организмов указывает на принадлежность водохранилища к водоемам мезосапробныого типа. Средние величины индекса сапробности воды в водохранилище изменялись от 1,7 (весна) до 1,6 (лето), что позволило сделать вывод об умеренном загрязнении обследованных участков водохранилища.

EXPRESSION OF RECOMBINANT P24 PROTEIN IN ESCHERICHIA COLI FOR SEROLOGICAL DIAGNOSIS OF BOVINE LEUKOSIS
Authors: Baltin K  , Shustov A  , Khassenov B.
Published: December 2021

Bovine leukemia is an infectious lymphoproliferative disease in cattle caused by the bovine leukemia virus (BLV). Production losses associated with BLV include increased cull rates, decreased milk production, or reduced fertility. Serological tests are used for diagnosis of BLV, of which the most sensitive is enzyme-linked immunosorbent assay (ELISA). Capsid p24 protein is a diagnostically important antigen of the BLV. The gene of p24 protein was cloned into pET-28 plasmid vector. The recombinant p24 antigen was obtained by using Escherichia coli ArcticExpressRP(DE3)_pET-28/р24 strain. The total yield of the purified p24 protein was 76 mg. Testing of the recombinant p24 protein on control sera showed that the p24 binds to positive control sera and has high antigenic activity. The pilot testing of the recombinant p24 protein on 48 animal samples resulted in 83% positive and 17% negative. The results indicate that the recombinant p24 protein is promising in enzyme-linked immunosorbent assay for the diagnosis of bovine leukemia.

Turist rehberinin iletişim becerisi turistlerin tur deneyimleri ve tur memnuniyetleri açısından oldukça önemli bir faktör olarak görülmektedir. Turist rehberinin iletişim becerisinin algılanması noktasında tur grubunda yer alan ziyaretçilerin yaş guruplarının değişkenlik göstermesi ve cinsiyetlerinin farklılaşması turist rehberinin iletişim yeterliliğini gözden geçirerek davranış sergilemesi ihtiyacını doğurmaktadır. Turist rehberinin iletişim becerisinde turistlerin yaş ve cinsiyet unsurlarının beraber yer aldığı bir çalışmanın literatürde oluşturduğu boşluk tespit edilmiştir. Mevcut çalışma ile bu boşluğun giderilmesine katkı sağlanması amaçlanmaktadır. Araştırmanın temel amacı turist rehberinin iletişim becerisini algılamada turistlerin yaş ve cinsiyet değişkenlerinin farklılık oluşturup oluşturmadığını ortaya koymaktır. Araştırma verileri Kapadokya Bölgesi’nin Nevşehir ilini ziyaret eden yabancı turistlerden anket aracılığıyla toplanmıştır. 300 kişiden elde edilen verilerin analizlerine göre, turistlerin hem cinsiyet hem de yaş faktörlerinin turist rehberinin iletişim becerisinin algılanmasında herhangi bir anlamlı farklılık oluşturmadığı sonucuna ulaşılmıştır.
Real eﬀective exchange rate and unemployment across post-transition Europe
Authors: Bošnjak Mile
Published: December 2021

Purpose: The aim of this paper is to examine the co-movement between the real effective exchange rate and unemployment across post-transition Europe.
Methodology: The research data sample in this paper consists of monthly data from 2000M1 to 2019M6 for ten European post-transition countries. After standard correlation analysis, the research followed a wavelet coherence approach, provided time-series analysis in the time-frequency domain and illustrated evolution of the co-movements in the observed period.
Results: Conventional approach research results suggest no significant correlation between variables under consideration in cases of Poland and Lithuania. In cases of Latvia and Slovenia, standard correlation coefficients were positive and not in line with the theory. Correlation coefficients supported the theoretical assumption in six other countries included in the study. Wavelet coherence analysis results provided deeper insights into the relationship over time and the frequency domain. Empirical results gained in this research revealed a decline in the unemployment rate accompanied by depreciation of the real effective exchange rate as a prominent pattern at the beginning of the observation period suggesting pro-cyclical monetary policy.
Conclusion: During the crisis of 2008 no link between variables under consideration was confirmed, while after the crisis empirical results were in line with the theoretical assumption, suggesting that depreciation of the real effective exchange rate might be used as an instrument to boost employment.

Authors: Hladika Mirjana , Poljašević Jelena , Grbavac Josipa
Published: December 2021

Purpose: One of the ways to enhance transparency and usefulness of audit reports is to include information on key audit matters (KAMs). In this paper, based on the presented KAMs, we investigate transparency of audit reports of listed companies in Bosnia and Herzegovina and in Croatia.
Methodology: For the purposes of this research, we collected and systematised data from published audit reports and then analysed them by means of descriptive statistical methods.
Results: The research results show that in Croatia only a few audit reports lack a section on KAMs and there is no difference between the audit reports issued by the Big Four and the reports of other audit firms. In Bosnia and Herzegovina, most audit reports do not include a section on KAMs, but, unlike the Big Four, who disclose at least one KAM, other audit firms generally do not present any. Additionally, the research results show differences in the number of communicated KAMs between the audit reports prepared by the Big Four in Croatia and their reports for Bosnia and Herzegovina. There are also differences in the type of KAMs used in the two observed countries.
Conclusion: Having analysed the situation in the two developing countries, we obtained different results. The discrepancies mainly stem from the varying degrees of transparency of the audit profession in each country.

Authors: Leko Šimić Mirna , Pap Ana
Published: December 2021

Purpose: The purpose of this research is to analyze the changes in Croatian Generation Z buying behavior due to the COVID-19 pandemic. As a result of the pandemic, all governments have imposed different measures that directly and indirectly impact consumer behavior. Recent studies have mostly recorded a dynamic increase in online shopping, stockpiling, and change in priorities from luxury to basic goods. This study will specifically look into the relation between Generation Z buying behavior change and their exposure to the COVID-19 pandemic as well as its impact on their perception of the quality of life.
Methodology: A sample of 442 Generation Z respondents from Croatia was analyzed using ANOVA to identify buying behavior changes concerning the level of their exposure to COVID-19. The analysis also included a potential correlation between buyer behavior change and their perception of the quality of life.
Results: The statistical analysis has confirmed the increase of online shopping and stockpiling in the group of respondents who were exposed to self-isolation and those who have not been exposed to COVID-19, but there was no correlation with their perception of the quality of life change as a result of forced buying behavior change.
Conclusion: Generation Z is identified as an e-generation, born and brought up in a digital environment. Although the pandemic has forced them to switch even more to online shopping, they do not perceive the exposure to the COVID-19 pandemic to impact their quality of life.

Abstract. Long-range transport of continental emissions has a far-reaching
influence over remote regions, resulting in substantial change in the size,
morphology, and composition of the local aerosol population and cloud
condensation nuclei (CCN) budget. Here, we investigate the physicochemical
properties of atmospheric particles collected on board a research aircraft
flown over the Azores during the winter 2018 Aerosol and Cloud Experiment in
the Eastern North Atlantic (ACE-ENA) campaign. Particles were collected
within the marine boundary layer (MBL) and free troposphere (FT) after
long-range atmospheric transport episodes facilitated by dry intrusion (DI)
events. Chemical and physical properties of individual particles were
investigated using complementary capabilities of computer-controlled
scanning electron microscopy and X-ray spectromicroscopy to probe particle
external and internal mixing state characteristics. Furthermore, real-time
measurements of aerosol size distribution, cloud condensation nuclei (CCN)
concentration, and back-trajectory calculations were utilized to help bring
into context the findings from offline spectromicroscopy analysis. While
carbonaceous particles were found to be the dominant particle type in the
region, changes in the percent contribution of organics across the particle
population (i.e., external mixing) shifted from 68 % to 43 % in the MBL
and from 92 % to 46 % in FT samples during DI events. This change in
carbonaceous contribution is counterbalanced by the increase in inorganics
from 32 % to 57 % in the MBL and 8 % to 55 % in FT. The
quantification of the organic volume fraction (OVF) of individual particles
derived from X-ray spectromicroscopy, which relates to the multi-component
internal composition of individual particles, showed a factor of 2.06 ± 0.16 and 1.11 ± 0.04 increase in the MBL and FT, respectively, among DI
samples. We show that supplying particle OVF into the κ-Köhler
equation can be used as a good approximation of field-measured in situ CCN
concentrations. We also report changes in the κ values in the MBL from
κMBL, non-DI=0.48 to κMBL, DI=0.41, while changes in the FT result in κFT, non-DI=0.36 to κFT, DI=0.33, which is consistent with enhancements in OVF followed by the DI
episodes. Our observations suggest that entrainment of particles from
long-range continental sources alters the mixing state population and CCN
properties of aerosol in the region. The work presented here provides field
observation data that can inform atmospheric models that simulate sources
and particle composition in the eastern North Atlantic.
