Authors: Vrăjitoru Eugen-Silviu , Boscoianu Mircea , Boscoianu Elena-Corina 
Published: July 2021

Abstract
The application is focused on strategies for portfolio management in the case of hedge-funds for emerging markets taking into account the severe constraints for a real-world implementation. In the case of Romanian capital market, the design of a hedge-fund architecture should respond to the typical constraints for using alternative strategies. Beyond the liquidity problems there exits only a limited set of alternative instruments and strategies with impact on diversification, on the functionality and efficiency. The objective is to develop a better understanding of alternative actions and innovations for real adaptation of the architecture of a hedge-fund at these emerging market conditions, especially the lack of short and hedging instruments and the liquidity problems. Based on this new innovative framework that could capture the value of multiple rotating satellite sub-portfolio paradigm, as an active strategy, it is possible to build a different paradigm for active portfolio management in a dynamic manner. Based on an adequate dynamic of rotation of these sub-portfolios it results an optimal risk- return-liquidity profile for the whole hedge-fund portfolio, adaptable for different contexts.

Published: July 2021

Introduction. Theory and research support the idea that subjective well-being (positive / negative affect and life satisfaction) is a substantial construct in understanding psychological well-being and mental health. The relevance of life satisfaction in variables affecting psychological well-being has been studied. Life satisfaction in adolescents and its association with sex, age, parental educational styles, peer attachment and emotional intelligence was researched. Groups were compared according to degree of life satisfaction and its relationship with these variables. Method. The sample was composed of 285 secondary school students (49.8% male), average age 15.09 years (12 to 19), and self-report measures of variables were applied to be analyzed: Satisfaction with Life Scale-Child (SWLS-C), Parental Educational Style of Adolescents, Inventory of Parent and Peer Attachment (IPPA) y Trait Meta-Mood-Scale-48 (TMMS-48). Results. Results showed a significant high level of satisfaction among adolescents. A significant higher score among boys compared to girls was confirmed, as in the younger compared to older. Correlations were statistically significant between life satisfaction and all dimensions from Parental Educational Style analyzed, except Behavioral Control; with Alienation and Confidence of Peer Attachment; and with Emotional Intelligence Clarity and Repair, as well as statistically significant differences among satisfaction groups in 12 of the 19 variables analyzed. Discussion and Conclusion. Promoting life satisfaction in adolescents is increasingly relevant, due to the role it may play in achieving good psychological adjustment, thus contributing to the promotion and prevention of mental health.
Teacher Engagement Mediates Self-Efficacy and Classroom Management: Focus on Indonesian Primary Schools

Published: July 2021

Introduction. The numbers of students with special needs studying in regular classes is increasing every year. This increase has consequences for teachers, who must manage classrooms to meet the students’ diverse needs and characteristics. The contributing factor to successful inclusive education is teachers’ self-efficacy in practicing it. Successful implementation of inclusive education, on the other hand, classroom management can be viewed as performance influenced by the extent to which teachers are involved in their work, that is, teachers’ “engagement.” Method. This quantitative correlational study aimed to determine whether teachers’ engagement mediates self-efficacy in inclusive practice and classroom management. A total of 242 inclusive primary school teachers in DKI Jakarta-Indonesia, completed three self-report questionnaires. Results. Teachers’ engagement significantly acts as mediator in the correlation between teachers’ self-efficacy and their classroom management. Discussion and Conclusion. Using motivational process in the job-demand model, results show that teachers’ self-efficacy functions as a personal resource in implementing inclusive education. This means that teachers’ self-efficacy conducted by teachers first raises the condition of the teacher involved in the role of work, before finally influencing the extent to which the teacher managed the classroom. Therefore that overall student, including students with special needs, get the optimal educational benefits.

Published: July 2021

Introduction. Teachers are invited to seek answers to many questions on their professional growth path. This article aims at drawing attention to their motivational behaviour in teaching school students. According to the theory of self-determination, appropriate motivating (that is, autonomy-supportive) behaviour of teachers can respond to a child’s essential psychological needs, and thus enable him or her to engage in the teaching and learning process. Therefore, the goal of this study is to examine the relationship between teachers’ motivational behaviour and student engagement. Method. The sample was composed of 687 students. Two measuring instruments were used: Learning Climate Questionnaire (LCQ) (Black & Deci, 2000) and Student Engagement Scale (Lam et al., 2014). Descriptive statistics, t test, ANOVA, correlational analyses, and multiple linear regression analyses were used to analyse the data. Results. The research results suggest that teachers’ motivational behaviour (students’ perceived level of autonomy-supportive teaching) significantly predicts student engagement. The studied Lithuanian children are characterised by the same engagement as children from all over the world; they see the meaning of their work and focus on it. Discussion and Conclusion. The conducted research also confirms a universal trend that boys are less involved than girls, although there were no statistically significant differences in the perceived level of teachers’ autonomy-supportive behaviour (for boys and girls).

Work From Home is the system chosen by the government in 2020 due to the spread of the Corona virus, with this system it is hoped that it can maintain social distancing, namely reducing people's mobility, maintaining physical distance, and reducing crowds so that it is expected to reduce the risk of corona virus transmission and employee safety. The WFH system has high flexibility, this is to support employee balance between work and life. This work system that changes to WFH in a fast period of time makes workers experience stressful conditions such as feelings of anxiety or prolonged worry, especially when they live under one roof with many people. In implementing WFH, workers need a comfortable and quiet workplace to help focus on work, although currently various activities such as studying and working are carried out from home, ergonomics is still important and cannot be ruled out. Apart from ergonomics, it is also necessary to pay attention to the layout or layout of a good work facility by considering comfort, security and movement so as to provide safety and security for the people who work in it. This study uses an analytical method through a qualitative approach, in this way it is expected to find out the effect of what things can cause stress for workers due to WFH, especially in terms of the interior and its effect on work effectiveness.

Authors: Pascual Juan Silvestre Grecia , Chan Kevin Ivan Peñaverde , Khu Kathleen Joy Ong-Lopez 
Published: July 2021

Background:
Cough is one of the most common symptoms of coronavirus disease 2019 (COVID-19) infection. This relatively benign symptom may lead to serious sequelae, especially in postoperative neurosurgical patients.

Case Description:
Here, we report a case of bone flap displacement, pseudomeningocele formation, and consequent cerebrospinal fluid leak in a patient with COVID-19 infection who recently underwent craniotomy for excision of cerebral metastasis. We highlight the pathophysiologic mechanisms of cough that may cause increased intracranial pressure (ICP), leading to the postoperative morbidity.

Conclusion:
Aside from additional risks to the patient’s health and increased treatment costs, these complications also lead to subsequent delays in the management of the underlying disease. Symptomatic treatment of cough is advised to prevent complications resulting from increased ICP.

A representação do processo precipitação-vazão por meio de modelos hidrológicos conceituais visa quantificar o volume escoado em uma bacia como consequência de uma determinada precipitação. Aliados a eles, os índices têm sido uma ferramenta útil para quantificar eventos extremos, como o Soil Moisture Index (TMI) que foi formulado a partir do modelo hidrológico Tank Model. Desta forma, o objetivo deste trabalho foi aplicar o Tank Model para a bacia do rio Perdizes, em Cambará do Sul (RS), e avaliar o desempenho do TMI para prever a ocorrência de cheias, limiar este utilizado para o fechamento da Trilha do rio do Boi, no Parque Nacional de Aparados da Serra (PNAS). Os dados utilizados na simulação foram obtidos pelas estações meteorológica e fluviométrica instaladas na bacia. Após a calibração e validação de três séries históricas no Tank Model, os valores obtidos do TMI foram comparados com os dias que a Trilha foi fechada, a partir de altos níveis registrados no rio Perdizes. O TMI demonstrou que o nível utilizado para fechar a Trilha do rio do Boi correspondeu a cheias em 72% das vezes. Portanto, o TMI mostrou bom desempenho ao indicar a ocorrência de cheias na área estudada, sendo uma ferramenta útil para a tomada de decisões na gestão do PNAS. Application of the Tank Model as a Management Tool in the Perdizes River Basin - Cambará do Sul/RS.ABSTRACTThe representation of the rainfall-runoff process by means of conceptual hydrological models aims to quantify the volume drained in a basin as result of a specific precipitation. Allied to them, the indices have been a useful tool to quantify extreme events, such as the Tank Moisture Index (TMI) which was formulated from the Tank Model. Thus, the objective of this work was to apply the Tank Model to the Perdizes river basin, in Cambará do Sul (RS), and to evaluate the performance of the TMI to predict the occurrence of floods, the threshold used for the closure of the Rio do Boi trail, in the Aparados da Serra National Park (PNAS). The data used in the simulation were obtained at the meteorological and fluviometric stations installed in the basin. After the calibration and validation of three historical series in the Tank Model, the values obtained in the TMI were compared with the days when the Trail was closed, from high levels recorded in the Perdizes river. The average TMI values demonstrated that the level used to close the Rio do Boi Trail corresponded to floods 72% of the time, and the median, 75%. Therefore, the TMI showed good performance in indicating the occurrence of floods in the study area, being a useful tool for decision making in the PNAS management.Keywords: Tank Moisture Index, trail closure, Aparados da Serra National Park.

Nesse estudo foi aplicada uma metodologia de classificação dos eventos de El Niño em seus diferentes tipos (Central, Leste e, quando ambos ocorrem concomitantemente, MIX) no período de janeiro de 1950 a março de 2019. Além disso, os tipos de El Niño foram separados por estação do ano e considerando as diferentes condições de anomalias de temperatura da superfície do mar no oceano Atlântico Tropical Sul (neutras quando ocorrem anomalias de temperatura entre -0,5º e 0,5ºC; quentes quando as anomalias são superiores a 0,5ºC e frias quando as anomalias são inferiores a -0,5ºC). Com base nas combinações de ocorrência de cada tipo de EN e anomalias de temperatura da superfície do mar no Atlântico Tropical Sul, foram determinadas as anomalias de precipitação na América do Sul. Os diferentes tipos de El Niño são mais frequentes quando há condições neutras no Atlântico Tropical Sul. Com relação às anomalias de precipitação na América do Sul, os eventos de El Niño Leste e MIX, em geral, mostram padrão similar na distribuição espacial das anomalias, mas com os eventos MIX mostrando sinal mais fraco. As anomalias de temperatura da superfície do mar no Atlântico Tropical Sul quando negativas ajudam a fortalecer as condições secas entre o norte das regiões norte e nordeste do Brasil propiciadas pelos eventos de El Niño. Influence of the Different Types of El Niño in the Precipitation over South America A B S T R A C TIn this study, a specific methodology was applied to classify El Niño events into their different types (Central, East and when both occur at the same time, MIX) from January 1950 to March 2019. In addition, the types of El Niño were separated by season and considering the conditions of sea surface temperature anomalies on the South Tropical Atlantic Ocean (neutrality: temperature anomalies between -0.5º and 0.5ºC, warm: anomalies above 0.5ºC and cold: anomalies below -0.5ºC). Based on in the combination of different types of El Niño and sea surface temperature anomalies on the South Atlantic Tropical Ocean, precipitation anomalies over South America were computed. The different types El Niño occur, in general, under neutral conditions on the Atlantic Ocean. The events of El Niño - East and MIX, in general, present a similar pattern in the spatial distribution of the precipitation anomalies over South America, but with the MIX events showing weaker signal. Sea surface temperature anomalies in the Tropical South Atlantic when negative, they help to strengthen the dry conditions between the north of the north and northeast regions of Brazil caused by the El Niño events.Keywords: atmospheric circulation, anomaly conditions, tropical oceans, climate
