Published: April 2022

According to the Water Framework Directive (WFD), biological quality elements constitute the basis for assessing ecological status of surface
waters. Biological communities are good indicators of water quality because they reflect environmental conditions over time and do not require frequent sampling. The main aims were to assess trophic and ecological status of the Lake Visovac (Krka River hydrosystem, South Croatia) using phytoplankton together with supportive physico-chemical parameters, eutrophication status and impact indicators. We also tested the viability of Chlorophyll-a (Chl-a) and Hungarian Lake Phytoplankton Index (HLPI) as proposed metrics in the standard regulatory monitoring procedure. The phytoplankton samples, Chl-a and physical- chemical parameters were taken on a monthly basis from April to September in 2016
and 2019. In 2016, the most dominant species was Pantocsekiella ocellata (Pantocsek) K.T.Kiss & Ács, while in 2019 it was accompanied by Ceratium hirundinella (O.F.Müller) Dujardin. According to
Chl-a, Lake Visovac was within the limits of oligo- to mesotrophic status. Based on the HLPI index, the Lake ecological status was assessed
as Good. Chl-a showed a statistically significant positive correlation with temperature, while HLPI was positively correlated with oxygen and Secchi depth. We propose the use of Chl-a for rapid bioassessment on a weekly basis, whilst more complex HLPI index should be applied monthly. Further improving the confidence level of the metrics used to assess the
ecological status and a comprehensive revision of boundaries for included indicators is of fundamental importance.

Published: April 2022

Sarcomas are a heterogeneous group of malignant tumors that arise from mesenchymal cells and can arise anywhere in the body, whether it is soft tissue or bone. Epidermal growth factor receptor (EGFR) expression in pediatric sarcomas is explored in the current study. A key feature of EGFRs is their general involvement in signal transduction and oncogenesis, making them one of the most studied receptor protein-tyrosine kinase families. The study included 104 archived formalin-fixed paraffin-embedded blocks assessed using immunohistochemical stains for EGFR expression in rhabdomyosarcoma, osteosarcoma, and Ewing's sarcoma. EGFR gene copy number was analyzed by dual silver in situ hybridization (DISH). EGFR was positively expressed in 56.7% of pediatric sarcoma. Immunostaining for EGFR was significantly associated with deep large tumors, stage, and histologic grade. Significantly, lower chances of overall survival were observed with elevated levels of EGFR five years post-diagnosis. EGFR staining identified independent risk factors for poor patient outcomes. The results of in situ hybridization did not indicate EGFR gene amplification in any of the cases assessed. EGFR overexpression was an independent predictor of pediatric sarcoma outcome, which is highly associated with histologic grade and stage. Results indicate EGFR inhibitors should be potentiated and directed against pediatric sarcoma.

Osteoarthritis, which typically arises from aging, traumatic injury, or obesity, is the most common form of arthritis, which usually leads to malfunction of the joints and requires medical interventions due to the poor self-healing capacity of articular cartilage. However, currently used medical treatment modalities have reported, at least in part, disappointing and frustrating results for patients with osteoarthritis. Recent progress in the design and fabrication of tissue-engineered microscale/nanoscale platforms, which arises from the convergence of stem cell research and nanotechnology methods, has shown promising results in the administration of new and efficient options for treating osteochondral lesions. This paper presents an overview of the recent advances in osteochondral tissue engineering resulting from the application of micro- and nanotechnology approaches in the structure of biomaterials, including biological and microscale/nanoscale topographical cues, microspheres, nanoparticles, nanofibers, and nanotubes.

Рассматривается геодинамическая история развития региона, расположенного на стыке Русской, Скифской и Туранской плит, где сосредоточены значительные ресурсы углеводородов. Приведен краткий обзор представлений различных исследователей о строении и основных тектонических элементов региона. В истории формирования современной структуры Каспийского региона выделяются и описываются два основных этапа: палеозойский и мезозойско-кайнозойский. На основе анализа специфических локальных структурных форм в Каракульско-Смушковской зоне, где оси складок выгнуты в северо-западном направлении и их крылья с этой стороны являются наиболее крутыми делается вывод о правостороннем смещении Скифско-Туранской плиты в предартинское время, в запад-северо-западном направлении, которое привело к образованию складок в Каракульско-Смушковской зоне, суборогенных структур «кряжа Карпинского», закрытию пролива на продолжении Сарпинского мегапрогиба и, тем самым, лишило связи бассейна ПВ с Пара-Тетисом. Следующий этап тектогенеза, существенно изменивший структурный план Каспийского региона, произошел на границе палеозойской и мезозойской эр. В это время произошел раскол единой ранее Скифско-Туранской плиты, и ее Южно-Мангышлакская часть по Мангышлакско-Центрально-Устюртскому разлому сместилась в юго-восточном направлении. Если в палеозое региональный наклон пластов в пределах южных районов ПВ был на север, то в мезокайнозое он сменился на противоположный – южный. Следствием такой перестройки стало образование специфического Азгирского разлома, активно живущего по настоящее время.

Bangladesh like other developing countries of the world has been striving to eradicate poverty after getting independence in 1971 and the country was considered as one of the poorest with about 70 percent poverty and only $200 per capita income in 1973-74. The present study analyses various data on poverty from the period 1971 to 2019 and finds that the country has reduced its poverty significantly to 10.5 percent in 2019 with more than $1909 per capita income. The poverty headcount ratio has decreased by more than 50% in the last 49 years. This study using National Households Income and Expenditure Survey (HIES) data of various years and also using other international organizations’ poverty-related data tries to explore the poverty scenario of Bangladesh from 1974 to 2019 and to examine some new aspects of regional poverty in Bangladesh. The country has a great achievement in the absolute poverty reduction during these periods, but these poverty reduction trends are somewhat relatively lower than some neighboring countries (e.g India, Nepal, Bhutan). In addition, though the absolute poverty rate has been reduced at the national level (10.5% in 2019), the present study finds a huge disparity in poverty reduction at the regional level in Bangladesh. Poverty rates are still more than double as compared to the state poverty rate in some districts of Bangladesh. This paper shows that the regional inequalities, income inequalities, old aged people, widows, uneducated and unskilled labor, various tribal groups, and various forms of poverty throughout the life cycle are revealing disparity of poverty in the rural area of Bangladesh.

Published: April 2022

Introduction: A considerable proportion of patients hospitalized with coronavirus disease 2019 (COVID-19) acquired bacterial infections. The aim of this study was to investigate the etiology and antimicrobial resistance of bacterial co-infection for more informed antimicrobial treatment.

Methods: This retrospective study reviewed electronic medical records of all the patients hospitalized with COVID-19 in the Northern Lebanon, Nini Hospital between august 2020-september 2021. According to the inclusion and exclusion criteria, patients who acquired bacterial infection were enrolled. Demographic, etiology and antimicrobial resistance data of the co-infection were collected.

Results: The rate of infection by Gram-negative bacteria was 61.7%, while the rate of infection by Gram-positive bacteria was 23.4%. Escherichia coli was the dominant species isolated in this study (25.5%), followed by Candida spp (14.9%). With regard to fungal infection, there were 14.9% cases of yeast infection. The respiratory infection was the majority (42.5%), followed by blood infection (32%) and urine infection (25.5%). The analysis of antibiotics sensitivity results showed us that 44.4% of isolated Enterobacteriaceae were resistant to carbapenem, 16.66% were secretors of ESBL. We noted that 27.77% of Enterobacteriaceae were XDR. All isolates of Staphylococcus aureus were resistant to the methicillin.

Conclusion: Bacterial co-infection may occur in patients hospitalized with COVID-19 and lead to high mortality. Gram-negative bacteria, especially Escherichia coli, S. maltophilia, and P. aeruginosa were the main bacteria, and the resistance rates of the major isolated bacteria were generally high.

Anisotropy of Magnetic Field Spectra at Kinetic Scales of Solar Wind Turbulence as Revealed by the Parker Solar Probe in the Inner Heliosphere

Using the Parker Solar Probe data taken in the inner heliosphere, we investigate the power and spatial anisotropy of magnetic field spectra at kinetic scales (i.e., around sub-ion scales) in solar wind turbulence in the inner heliosphere. We find that strong anisotropy of the magnetic spectra occurs at kinetic scales with the strongest power in the perpendicular direction with respect to the local magnetic field (forming an angle θ
B with the mean flow velocity). The spectral index of the magnetic spectra varies from −3.2 to −5.8 when the angle θ
B changes from 90° to 180° (or 0°), indicating that strong anisotropy of the spectral indices occurs at kinetic scales in the solar wind turbulence. Using a diagnosis based on the magnetic helicity, we show that the anisotropy of the spectral indices can be explained by the nature of the plasma modes that carry the cascade at kinetic scales. We discuss our findings in light of existing theories and current development in the field.
Twin Extreme Ultraviolet Waves in the Solar Corona
Authors: Zheng Ruisheng , Wang Bing , Zhang Liang , Chen Yao , Erdélyi Robertus
Published: April 2022

Solar extreme ultraviolet (EUV) waves are spectacular propagating disturbances with EUV enhancements in annular shapes in the solar corona. These EUV waves carry critical information about the coronal magnetized plasma that can shed light on the elusive physical parameters (e.g., the magnetic field strength) by global solar coronal magnetoseismology. EUV waves are closely associated with a wide range of solar atmospheric eruptions, from violent flares and coronal mass ejections to less energetic plasma jets or mini-filament eruptions. However, the physical nature and driving mechanism of EUV waves are still controversial. Here, we report the unique discovery of twin EUV waves (TEWs) that were formed in a single eruption with observations from two different perspectives. In all earlier studies, a single eruption was associated at most with a single EUV wave. The newly found TEWs urge us to revisit our theoretical understanding of the underlying formation mechanism(s) of coronal EUV waves. Two distinct scenarios of TEWs were found. In the first scenario, the two waves were separately associated with a filament eruption and a precursor jet, while in another scenario, the two waves were successively associated with a filament eruption. Hence, we label these distinguished scenarios as “fraternal TEWs” and “identical TEWs,” respectively. Further, we also suggest that impulsive lateral expansions of two distinct groups of coronal loops are critical to the formation of TEWs in a single eruption.

We report the archival discovery of Lyα emission from the bright ultraviolet galaxy Y002 at z = 7.677, spectroscopically confirmed by its ionized carbon [C ii] 158 μm emission line. The Lyα line is spatially associated with the rest-frame UV stellar emission (M

⊙ yr−1 from the far-infrared (FIR) wavelength range, which globally places Y002 on the SFR(UV+IR)–L
[C II] correlation observed at lower redshifts. In terms of velocity, the peak of the Lyα emission is redshifted by Δv
Lyα
∼ 500 km s−1 from the systemic redshift set by [C ii] and a high-velocity tail extends up to ∼1000 km s−1. The velocity offset is up to ∼3.5× higher than the average estimate for similarly UV-bright emitters at z ∼ 6–7, which might suggest that we are witnessing the merging of two clumps. A combination of strong outflows and the possible presence of an extended ionized bubble surrounding Y002 would likely facilitate the escape of copious Lyα light, as indicated by the large equivalent width EW0(Lyα)

Published: April 2022

We evaluate color-based classifiers in a synthesis of Pan-STARRS, 2MASS, UKIDSS, and AllWISE catalogs to identify ultracool dwarfs (UCDs). Using the Best et al. compilation of UCDs and a sample of background sources as our training set, we constructed a two-tier random forest model to segregate UCDs from non-UCDs and sort them into spectral subgroups. We also developed a regressor model to infer numerical classifications. Our classifier models achieved accuracies of 97%–99%, while our regressor model achieved a classification accuracy of 0.64 subtypes for classifications M5–T8. We applied these models to a 7 deg2 region with overlapping survey data and identified 336 UCD candidates, of which 26 are previously identified UCDs and 17 are extragalactic sources.
Comparison of Two Analytic Energy Balance Models Shows Stable Partial Ice Cover Possible for Any Obliquity
Authors: Landgren Ekaterina , Nadeau Alice
Published: April 2022

In this study, we compare two analytic energy balance models with an explicit dependence on obliquity to study the likelihood of different stable ice configurations. We compare the results of models with different methods of heat transport and different insolation distributions. We show that stable partial ice cover is possible for any obliquity, provided the insolation distribution is sufficiently accurate. Additionally, we quantify the severity of the transition to the snowball state as different model parameters are varied. In accordance with an earlier study, transitions to the snowball state are more severe for higher values of the albedo contrast and energy transport across latitudes in both models; however, we find that the snowball transition is not equally likely across both models. This work is general enough to apply to any rapidly rotating planet and could be used to study the likelihood of snowball transitions on planets within the habitable region of other stars.
Antenatal Depression as a Stunting Risk Factor: A Systematic Review
Authors: Maulina Rifzul , Qomaruddin Mochammad Bagus , Sumarmi Sri , Fahrul Alfunafi , Haryuni Sri
Published: April 2022

BACKGROUND: Depression during pregnancy is often found and ignored even though depression has a negative impact not only on the mother but also on the fetus to adulthood. Stunting is a problem of lack of nutritional status that begins during pregnancy.
AIM: The purpose of this article is to systematically identify the description and relationship between depression during pregnancy and stunting in children.
METHOD: The approach used is the systematic review method to search articles. Articles were identified from 2010-2020 by conducting a literature search with the keywords "antenatal depression" OR "prenatal depression" OR "depression during pregnancy" and "stunting" in the electronic databases dataset by Sciencedirect, Pubmed Research Gate, and Google Scholar.
RESULTS: The search results found 1875 articles selected into 20 journal articles that match the inclusion criteria. CONCLUSION: The results found that depression during pregnancy correlated with risk factors for stunting. As a preventive measure, health workers, especially midwives, can provide psychological care in antenatal care by considering these factors.

Authors: Sarfika Rika , Huriani Emil , Mailani Fitri , Muthia Rahmi
Published: April 2022

BACKGROUND: Nurses are at high risk of experiencing stress when treating patients with COVID-19. The presence of an outbreak could also result in burnout among nurses due to job stress, poor hospital resources for the treatment, and inadequate support from family and friends. All of these related obstacles might be interfered with the intention of nurses to work during a pandemic. AIM: The objective of the study was to identify perceived stress and intention to work during the COVID-19 pandemic among nurses. METHODS: An online-based cross-sectional study was conducted among nurses in Indonesia. There were 238 responses received. Multiple regression analysis was used to examine for data analysis. RESULTS: There was a significant correlation between perceived stress and intention to work (p < 0.001). The regression model showed the variance in the perceived stress with other main predictors. CONCLUSIONS: To maintain an adequate workforce during the pandemic, hospital management should ensure adequate hospital goods supply and deploy retention strategies to retain clinically experienced nurses.

Published: April 2022

Clean energy potential can be used on a large scale in order to achieve cost competitiveness and market effectiveness. This paper offers sufficient information to choose renewable technology for improving the living conditions of the local community while meeting energy requirements by employing the notion of q-rung orthopair fuzzy numbers (q-ROFNs). In real-world situations, a q-ROFN is exceptionally useful for representing ambiguous/vague data. A multi-criteria decision-making (MCDM) is proposed in which the parameters have a prioritization relationship and the idea of a priority degree is employed. The aggregation operators (AOs) are formed by awarding non-negative real numbers known as priority degrees among strict priority levels. Consequently, some prioritized operators with q-ROFNs are proposed named as "q-rung orthopair fuzzy prioritized averaging ($\text{q-ROFPA} _d $) operator with priority degrees and q-rung orthopair fuzzy prioritized geometric ($\text{q-ROFPG} _d $) operator with priority degrees". The results of the proposed approach are compared with several other related studies. The comparative analysis results indicate that the proposed approach is valid and accurate which provides feasible results. The characteristics of the existing method are often compared to other current methods, emphasizing the superiority of the presented work over currently used operators. Additionally, the effect of priority degrees is analyzed for information fusion and feasible ranking of objects.
On $ f $-strongly Cesàro and $ f $-statistical derivable functions

Published: April 2022

In this manuscript, we introduce the following novel concepts for real functions related to $ f $-convergence and $ f $-statistical convergence: $ f $-statistical continuity, $ f $-statistical derivative, and $ f $-strongly Cesàro derivative. In the first subsection of original results, the $ f $-statistical continuity is related to continuity. In the second subsection, the $ f $-statistical derivative is related to the derivative. In the third and final subsection of results, the $ f $-strongly Cesàro derivative is related to the strongly Cesàro derivative and to the $ f $-statistical derivative.

Authors: Black Ernest , Kirkwood Kirk
Published: April 2022

This chapter provides a glimpse into the experiences of two Black male educational leaders and children of the Civil Rights Movement. Their parents migrated from the Jim Crow South to Detroit, Michigan, and Inglewood, California respectively, teaching them to work fervently and inspiring them to become educators. During their journey, the authors noticed that they had to be twice as good as their white peers to practice in educational institutions. However, they were committed to empowering their students and acquired the credentials and skills to become educational practitioners. As leaders in K-12 and higher education, they realized the significance of their personal narratives—which are connected to a rich legacy of activism, resilience, and collective resolve—to improve the lives and conditions of the Black community. This chapter informs current and future leaders about Black people's experiences within the U.S. education system. Principally, the authors highlight how cultural assets improve instructional practices, learning conditions, and academic outcomes for Black students.
Caregiver Teacher
Authors: Elkins Donna M.
Published: April 2022

Becoming a caregiver for two elderly parents in a remote rural area with limited internet access while also teaching online increased the author's awareness of students' challenges and interpersonal needs in online educational modalities. She realized how often students' interpersonal needs, as well as teachers' needs, go unmet in the online classroom. Students' messages may be misread when they are reaching out to teachers in attempt to meet their interpersonal needs through the teacher-student relationship. She argues that online teachers would be wise to rely on William Schutz's Fundamental Interpersonal Relations Orientation to inform their interactions with students. Rather than dismissing students' sometimes clumsily sought or expressed needs, responding to their needs as one human being to another creates relationships that retain and strengthen students' resilience. Vulnerability as a teacher and exploration of our shared “humanness” in all roles within higher education leads to a conclusion that calls for more direct interpersonal contact between teachers and students, not less.
Three Octobers
Authors: Minerva Kelly A.
Published: April 2022

Autoethnography is an important tool in feminist scholarship, one that routinely acknowledges the dangers of focusing on corporate and academic female leaders and overlooking the needs of women experiencing poverty. The author argues that when academic parents keep the narratives focused on research and service demands, they also dangerously sideline the needs of students. After March 2020, many of us moved metaphorical mountains to move classes online, only to find that students were often not up to the tasks we had set. Undoubtedly the situation was not the same for all students at different institutions, but for many working students from lower socio-economic classes demands multiplied and quickly became insurmountable. The intention of this autoethnography is to consider the ways that the struggles the author faces as a literature professor and as a mother working through the COVID-19 pandemic can help others empathize with students and bring practical change to our pedagogies and course policies.
Teach Real
Authors: Pacheco Jr. George
Published: April 2022

The demographic make-up of the students in higher education is changing. In an effort to keep up with this shift, higher education needs more non-white faculty in classrooms, administrative, and staff positions to present a viable target for incoming students. As more demographically diverse students enter into the classroom, faculty must also shift their pedagogical choices to a more relational environment to meet the needs of this new student body. The purpose of this chapter is to explicate the ways in which being “real” and authentic with students is a pedagogical choice that fosters an environment that leads to better learning for students. Faculty need to better understand the ways in which pedagogical development intersects with the salient parts of their own identities. This chapter also develops arguments for future directions in the ways faculty teach so they may connect these versions of themselves to better serve students through authentic human connection.
Classification of Polycystic Ovary Syndrome Based on Correlation Weight Using Machine Learning
Authors: Marreiros Marcelo , Ferreira Diana , Neto Cristiana , Witarsyah Deden , Machado José
Published: April 2022

Polycystic ovarian syndrome (PCOS) is the most common endocrine pathology in reproductive-age women worldwide. Research has shown that the application of machine learning (ML) and data mining (DM) can have a positive impact in this condition's diagnosis. This study aims to develop a model to identify patients with PCOS using different scenarios based on correlation weights. Five DM techniques were applied, namely random forest (RF), decision tree (DT), naive bayes (NB), logistic regression (LR), and artificial neural network (ANN), to determine the best model, which was the RF classifier. Additionally, the results show that the model was able to predict PCOS with 93.06% of accuracy, 92.66% of precision, 93.52% of sensitivity, and 92.59% of specificity. Compared with a previous work conducted by the authors, the feature selection-based solo on the correlation weight decreased the accuracy values by 1.9%, precision by 3.7%, sensitivity by 0.3%, and specificity by 3.6%.
Electronic Health Records Structuring Based on the OpenEHR Standard
Authors: Oliveira Daniela , Hak Francini , Guerra Helia , Abelha António
Published: April 2022

The growth of electronic health records (EHR) produced by health facilities has been exponential, leading to massive and heterogeneous data storage. This raises the need for secure, continuous, and interoperable data structuring between different legacy systems. The OpenEHR standard provides open data specifications that aim to overcome recognized gaps in the collection, storage, and management of clinical records. In this sense, this chapter describes a case study applied in an emergency context, where 14-year clinical records were restructured to an interoperable and standardized environment, according to the OpenEHR specifications.
Importance of E-Health in Human Life

E-health plays a significant role in giving valuable information to the people about human life. E-health is commercial and protected use of data about the health, information and communication technology (ICT), and its associates with the health-related directions and human health activities. ICT or e-health includes different interventions like telehealth, telemedicine, m-health (mobile health) e-health registers (EHR), big data, wearables, and uniform artificial intelligence. In life there is no time for paper and pen work in the countries, and they are change completely to the digitalization and sharing health information and patient health data through the online mode, which is more simple and successful healthcare improvements. Such healthcare apps are useful to us to lead better, well, and more fruitful lives. E-health can be one of the important hopeful aspects for providing community health benefits which incorporates a predictable medical system.
Challenges and Threats to Environmental Accounting and Reporting
Authors: Üçoğlu Derya
Published: April 2022

Conventional accounting practices are not sufficient to provide the necessary information demanded by the stakeholders. By environmental accounting and reporting, valuable information regarding the effects of activities of companies on the environment are identified and disclosed. Environmental accounting and reporting have numerous advantages, such as providing a basis for more efficient decision-making processes, optimization of company value, improved corporate image, and increased customer loyalty and investor trust. On the other hand, this chapter mainly focuses on the challenges and threats to environmental accounting and reporting and discusses the possible solutions to the problems identified and recommendations provided by prior literature.

This chapter contributes to the knowledge and understanding of recent trends in social and environmental accounting with the Sustainable Development Goal of the UN Agenda 2030. This study has two specific objectives: 1) to analyse the scientific production that crosses the area of SEA with SDG achievement, quantifying the articles published by year and by title of origin, by citation and research network by author, and by journal impact and 2) to identify publications by author, affiliation, and country and by type, subject, and funder. It is important to understand how sustainability accounting research might contribute to responsible business management towards SDG. A bibliometric analysis of articles published in journals in the Scopus database was carried out in the period between 2016 and 2021. The results of this study describe the current state of research in SEA and SDG achievement and provide a framework that can guide researchers.
Supply Chain Pressure on Environmental Management Systems Adoption
Authors: Keilhauer Moritz , Almeida Marta
Published: April 2022

As climate change is becoming more visible, individuals, governments, and firms around the globe increasingly try to mitigate their ecological impact. For companies, the implementation of (certified) environmental management systems (e.g., ISO 14001 or EMAS) can improve their environmental performance. Through a systematic literature review, the past and current research regarding the effects of supply chain pressure on the adoption of EMS is analysed and synthesized. In total, 59 papers are assessed in detail, revealing several research gaps. These include the lack of research on EMAS and the role of female CEOs.
Future Perspectives and Evolution of Citizen Participation in Government
Authors: Garcia Maria Jesus Garcia
Published: April 2022

A regulatory policy based on the idea of smart regulation takes the view that legislation and regulations serve the economy, and therefore, laws must be intended to create the conditions to improve national economies and economic growth, as laid down by the OECD and the European Union itself. Such a regulatory policy is informed by a set of principles which apply to both regulatory institutions and regulations, such as transparency, cooperation, accountability, efficiency, effectiveness, participation, and openness. This regulatory approach takes the view that regulations are of better quality when they have been influenced by citizens. As a consequence, smart regulation results in participatory democracy. Citizens collaborate with the government in the lawmaking process at an early stage and throughout the lifecycle of a legislative act by means of consultations. This chapter focuses on consultation as the principal mechanism for participatory democracy in the context of smart regulation law-making in the European Union.

Authors: Pimentel Liliana , De Oliveira Helena Maria Santos , Pinheiro Sara Vicente
Published: April 2022

In the current context, strongly marked by globalization, organizations have undergone a period of changes induced by economic, social, and political changes, which have led to changes in the relationships between individuals and society. In this way, organizations, through the implementation of new values and strategies, have established themselves as socially responsible organizations, characterized by their ethical essence. This chapter intends to evaluate the organizational virtuousness, affective well-being at work, and organizational citizenship behaviors, following the studies developed by Cameron et al. and by Rego et al., which relate organizational virtuosity, well-being at work, and behaviors of organizational citizenship. The study was applied in the municipalities of the Intermunicipal Community (CIM) – Trás-os-Montes, and 760 employees were surveyed. Findings indicate that perceptions of organizational virtuousness and well-being at work are related to organizational citizenship behaviors.
