Authors: Steshenko Ya. M. , Mazulin O. V. , Polishchuk N. M.
Published: October 2021

The main problem of modern phytotherapy is the medicinal plants that have a sufficient raw material base and contain a large number of biologically active substances. Treatment of diseases with synthetic drugs leads to the development of resistance to pathogenic microflora and the appearance of allergic reactions. Therefore, to solve this problem, it is necessary to find new plant-based antimicrobials that are safe for long-term use and have a wide spectrum of action.
The aim of the work was to study the antibacterial and fungicidal activity of the essential oil of Thymus x citriodorus (Pers.) Schreb. var. “Silver Queen”.
Materials and methods. The essential oil of Thymus x citriodorus (Pers.) Schreb. var. “Silver Queen” was used for the experimental part. To test the antimicrobial and antifungal action of the essential oil, reference test strains, gram-positive and gram-negative bacteria, as well as yeast-like fungi of the genus Candida were selected. The studies were performed in vitro using the disco-diffusion method.
Results. Studies have shown that the essential oil of Thymus x citriodorus (Pers.) Schreb. var. “Silver Queen” has a significant antibacterial effect against S. aureus ATCC 25923 (diameters of growth inhibition were 14.60 ± 1.52 mm) and fungicidal effect Candida albicans ATCC 885-6530 (29.30 ± 2.82 mm). Antibacterial activity of the essential oil was detected in relation to E. coli (19.60 ± 1.85 mm). It was experimentally proven that the essential oil had no bactericidal effect on the test strain of P. aeruginosa.
Conclusions. It was found that the essential oil of the studied hybrid species Thymus x citriodorus (Pers.) Schreb. var. “Silver Queen” shows a significant antibacterial activity and is promising for further research.
Search for antibacterial activity in a number of new S-derivatives (1,2,4-triazole-3(2H)-yl)methyl)thiopyrimidines
Authors: Karpenko Yu. V. , Panasenko O. I.
Published: October 2021

The relevance of the study of 1,2,4-triazole derivatives with pyrimidine fragment is due to the synthesis of potential broad-spectrum antibacterial drugs, low molecular weight inducers of interferon, and antitumor agents, search for molecular descriptors of their structure, important for establishing patterns “structure – biological activity”.
The aim of the work is a computer search for the antibacterial action of new hybrids of 1,2,4-triazole-3(2H)-thiol with a pyrimidine fragment in relation to 5 test cultures, to establish the dependence of “structure – action”.
Materials and methods. For an in-depth study of the antibacterial activity of derivatives of 1,2,4-triazole-3(2H)-thiol hybrids with a pyrimidine fragment, 4 test cultures of museum strains of gram-positive, gram-negative bacteria and one species of fungi were selected. In silico studies were performed using regression and classification QSAR models.
Results. Derivatives of 1,2,4-triazole-3(2H)-thiol hybrids with a pyrimidine moiety showed high antibacterial activity against gram-negative microorganisms (E. coli, P. aeruginosa). The obtained experimental results allowed to establish not only the role of the main structural features of the compounds in the manifestation of antimicrobial properties, but also to evaluate the effectiveness of the created classification and regression QSAR models. Based on the presented parameters for individual predictive QSAR models, it is possible to conclude about the effectiveness, stability and feasibility of using these models to search for new S-derivatives (1,2,4-triazole-3(2H)-yl)methyl)thiopyrimidines as promising antimicrobial agents.
Conclusions. It was found that the studied derivatives of hybrids of 1,2,4-triazole-3(2H)-thiol with a pyrimidine fragment showed high antibacterial activity against gram-negative microorganisms. The developed QSAR classification models based on the percentage of correctly predicted compounds (70 %) are the most effective in comparison with regression (50 %) for the search for new antimicrobial agents in a number of derivatives of hybrids 1,2,4 triazole-3(2H)-thiol with pyrimidine fragment.

Using a case study approach from past projects in Singapore, Australia, Cambodia, Thailand and Vietnam, we examine the benefits, but also some of the challenges, to implementing green space in urban design. Green space can have multiple physical and psychological wellbeing benefits, as well as environmental benefits, including urban runoff quantity and quality management, urban heat island abatement, air quality improvement, and noise reduction. Water sensitive urban design (WSUD) can be an important element of green space design and here we explore how modeling of ecosystem services and dynamic modeling of WSUD can help to facilitate sound planning and management decision making in support of green space implementation. As we illustrate with examples for Australia, Singapore and Cambodia, we believe that application of an urban ecosystem services modeling approach can elucidate environmental benefits of urban green space that otherwise may not be considered. Engineers may include dynamic modeling of WSUD in support of an urban master plan, or urban redevelopment, but generally urban planners are less conversant in applying models. We discuss some of the challenges to integrating multidisciplinary visioning and modeling of green space design and performance evaluation through our experience with a stormwater and wastewater design study for Cha Am, Thailand, that included landscape architecture and engineering classes at Thammasat University, Mahidol University, and AIT. Through a case study of Phnom Penh, we illustrate how modeling and 3D visualization can be used to effectively explore the benefits of green space. We conclude that a user-friendly decision support system is needed to integrate modeling and visualization tools and thereby bridge the gap between form and function in urban green space design.
What does Brazil know about the origin and uses of tree species employed in the housing sector? Perspectives on available species, origin and current challenges

Published: October 2021

Timber consumption is a complex discussion for the industry, in part because the issue has been marked by doubts about lineage and origin. This paper aimed to identify challenges related to species, origins and wood use in the Brazilian construction sector. Searches on corporate websites
and face-to-face interviews were used to identify involvement by species and origin in the domestic production of timber for housing. Relevant results were obtained for both methods since their margins of error were low. Forty exotic and nine native species were revealed to contribute significantly
to the construction sector. 'Grapia' and 'Angelim pedra' native woods and eight eucalypt and pine species were shown to be the most popular through both methodologies. Pine timber was found to be in greater demand than that of Eucalyptus species. Despite some lack of clarity relating to the
origin of certain species, the sector's status was better than expected. However, it still requires assertive actions to increase the use of legalized wood in order to favour product certification and integration into foreign markets.
Humans Use a Temporally Local Code for Vibrotactile Perception
Authors: Bhattacharjee Arindam , Braun Christoph , Schwarz Cornelius
Published: October 2021

Sensory environments are commonly characterized by specific physical features, which sensory systems might exploit using dedicated processing mechanisms. In the tactile sense, one such characteristic feature is frictional movement, which gives rise to short-lasting (<10 ms), information-carrying integument vibrations. Rather than generic integrative encoding (i.e., averaging or spectral analysis capturing the “intensity” and “best frequency”), the tactile system might benefit from, what we call a “temporally local” coding scheme that instantaneously detects and analyzes shapes of these short-lasting features. Here, by employing analytic psychophysical measurements, we tested whether the prerequisite of temporally local coding exists in the human tactile system. We employed pulsatile skin indentations at the fingertip that allowed us to trade manipulation of local pulse shape against changes in global intensity and frequency, achieved by adding pulses of the same shape. We found that manipulation of local pulse shape has strong effects on psychophysical performance, arguing for the notion that humans implement a temporally local coding scheme for perceptual decisions. As we found distinct differences in performance using different kinematic layouts of pulses, we inquired whether temporally local coding is tuned to a unique kinematic variable. This was not the case, since we observed different preferred kinematic variables in different ranges of pulse shapes. Using an established encoding model for primary afferences and indentation stimuli, we were able to demonstrate that the found kinematic preferences in human performance, may well be explained by the response characteristics of Pacinian corpuscles (PCs), a class of human tactile primary afferents.
DBscorer: An Open-Source Software for Automated Accurate Analysis of Rodent Behavior in Forced Swim Test and Tail Suspension Test

Published: October 2021

Forced swim test (FST) and tail suspension test (TST) are commonly used behavioral tests for screening antidepressant drugs with a high predictive validity. These tests have also proved useful to assess the non-motor symptoms in the animal models of movement disorders such as Parkinson’s disease and Huntington’s disease. Manual analysis of FST and TST is a time-consuming exercise and has large observer-to-observer variability. Automation of behavioral analysis alleviates these concerns, but there are no easy-to-use open-source tools for such analysis. Here, we describe the development of Depression Behavior Scorer (DBscorer), an open-source program installable on Windows, with an intuitive graphical user interface (GUI), that helps in accurate quantification of immobility behavior in FST and TST from video analysis. Several calibration options allow customization of various parameters to suit the experimental requirements. Apart from the readout of time spent immobile, DBscorer also provides additional data and graphics of immobility/mobility states across time revealing the evolution of behavioral despair over the duration of the test and allows the analysis of additional parameters. Such comprehensive analysis allows a more nuanced understanding of the expression of behavioral despair in FST and TST. We believe that DBscorer would make analysis of behavior in FST and TST unbiased, automated and rapid, and hence prove to be helpful to the wider neuroscience community.
THE MOTION OF A PARTICLE ON A WAVY SURFACE DURING ITS TRANSLATIONAL CIRCULAR OSCILLATIONS IN HORIZONTAL PLANES

The rough plane is a universal structural element of many machines and devices for sifting and separation of parts of technological material. The motion of particles on the horizontal plane, which performs oscillating rectilinear or circular motion, is the most studied. A wavy surface with a sinusoidal cross-sectional line as a working surface will significantly change the trajectories of their motion. The mathematical description of such a motion will change accordingly. The sliding of a particle in a plane will be a partial case of sliding on a wavy surface when the amplitude of the sinusoid is equal to zero. When the wavy surface oscillates and all its points describe circles, the motion of the technological material changes significantly. The regularities of the motion of material particles on such a surface during its circular translational oscillations in the horizontal planes are investigated in the article. Differential equations of relative particle displacement are compiled and solved by numerical methods. The trajectories of the particle sliding on the surface and the graphs of its reaction are constructed. A partial case of a surface is a plane, and the sliding trajectory of a particle is a circle. An analytical expression to determine its radius is found. During circular oscillations of a wavy linear surface with a cross section in the form of a sinusoid relative trajectory of a particle after stabilization of the motion can be closed or periodic spatial curves. To avoid the breakaway of the particle from the surface, the oscillation mode should be set, which takes into account the shape of the surface and the kinematic parameters of oscillations. With the diameter of the circle, which is described by all points of the surface during its oscillation, is equal to the period of the sinusoid, the trajectory of the relative motion of the particle can be a periodic curve. In this case, the particle moves in a direction close to the transverse, overcoming depressions and ridges. In other cases, the trajectory is a closed spatial curve, the horizontal projection of which is close to a circle. The found analytical dependencies allow determining the influence of structural and technological parameters of the surface on the trajectory of the particle.

Ukraine with her developed machine-building potential can take the deserving place in the production of small modular reactors. One of basic elements of small modular reactors equipment is steam generator. Among different types a deserving place is occupied by once-through steam generator. small modular reactors can exemplify to transport nuclear installation, for example KLT-40S. The calculation of hydraulic resistance is included in designing of steam generators, that it is necessary for the choice of pumps and optimization of structural parameters. In the presented article methodology of hydraulic calculation of once-through steam generator is examined with the coiling surface of heating. As a result of analysis of literature formulas were selected for the calculation of hydraulic resistance for four modes of flow: transverse flow of the coolant over horizontal coils, movement in bent tubes of a single-phase working fluid, boiling water and superheated steam. Results over of calculation of steam generators are brought by power 45 МВт with different structural parameters: diameter of coils, horizontal and vertical pitches of coils location in a bunch, speed of feedwater and coolant. The got results were verified by comparing to data of calculation on the code of ASPEN-TECH. It was found out as a result of research that increase of diameter of coils, as well as the increase of pitches of coils location in a bunch does not reduce hydraulic resistances, as expected, but increases them as a result of worsening of heat exchange and, accordingly, increase of heat-exchange surface. The increase of speed of coolant results in the height of resistance on the side of coolant and does not influence on resistance of working body. The increase of speed of feedwater increases resistance on the side of working fluid and does not influence on resistance of coolant.

Published: October 2021

Background: The efficacy of colchicine administration for coronary heart disease remains controversial. We conducted a systematic review and meta-analysis to explore the influence of colchicine administration versus placebo on treatment efficacy for coronary heart disease.
Methods: We have searched PubMed, Embase, Web of Science, EBSCO, and Cochrane Library databases through May 2021 for randomized controlled trials (RCTs) assessing the effect of colchicine administration versus placebo in patients with coronary heart disease. This meta-analysis was performed using the random-effects model.
Results: Six RCTs involving 6,321 patients were included in the meta-analysis. Overall, compared with control groups for coronary heart disease, colchicine intervention can significantly reduce major adverse cardiovascular events (odds ratio [OR] 0.74; 95% confidence interval [CI] 0.59 to 0.92; P = .006), but revealed no obvious impact on mortality (OR=0.93; 95% CI=0.63 to 1.36; P = .69), serious adverse events (OR 0.71; 95% CI 0.31 to 1.61; P = .41), or restenosis (OR 1.02; 95% CI 0.63 to 1.64; P = .95).
Conclusions: Colchicine treatment may be effective to reduce major adverse cardiovascular events in patients with coronary heart disease.

Authors: Cheng Xianfeng , Shen Dawei , Zhang Jie , Zhang Tao
Published: October 2021

Aortic valve myxoma is a rare benign cardiac neoplasm. The association of aortic valve myxoma with cardiogenic shock and acute myocardial infarction has been reported in few observations. We report the case of a 19-year-old male patient, who underwent chest pain for two weeks, then further examinations indicated a soft spherical mass on the left coronary cusp. The patient had sporadic cardiogenic shock and acute myocardial infarction during the preoperative preparation, and we carried out emergency effective cardiopulmonary resuscitation (CPR), followed by emergency surgical operation for aortic valve tumor.
Postoperative pathology showed it was a myxoma. The patient recovered smoothly and was discharged on postoperative day 7. Cardiogenic shock and acute myocardial infarction are very nonspecific, and we should be aware that patients with cardiogenic shock and acute myocardial infarction possibly suffer from aortic valve myxoma.
Stepping back: Reflecting on accessibility in integrated dance improvisation
Authors: Acton Kelsie
Published: October 2021

Finding more accessible ways to train, create, perform and work is a major concern of researchers and practitioners (Ajula & Redding, 2013, 2014) of integrated and disability dance. In the spring of 2017 eight dancer/researchers from CRIPSiE, an integrated, disability and crip dance company located in Edmonton, came together to investigate their practices of timing through a participatory performance creation process. Participatory performance creation values researcher reflexivity (Heron & Reason, 1997). In this paper I reflect on the way that collaboratively building an improvisation score, a series of tasks and prompts that the dancer/researchers responded to (Gere, 2003), created inaccessibility for one of the dancers/researchers, Robert. At the time I assumed that improvisation itself was inaccessible. Upon reflecting I realized that the improvisation was accessible and that Robert was improvising in ways valued by both the integrated improvisation literature and the other dancers/researchers.

Published: October 2021

Theatre has come to be one of the main artistic ways to convey the voices of people with disability to the general audience, and this includes people with language and communication disorders. This article aims to describe and discuss the activities of Le Théâtre Aphasique, a non-profit organization located in several cities in Quebec that delivers dramatic art workshops to people with aphasia, an acquired language disorder. Our interest is to understand how this activity has become a successful phenomenon in different disciplines, with different a priori theoretic frameworks, such as disability arts as well as rehabilitation sciences. Specifically, we suggest that the complexity and means of this activity are indeed the cause of its success given that 1) it allows people with different  communication abilities to participate, while 2) encouraging the presence of people with disabilities in the theatrical scene and 3) supporting the understanding and use of different communication styles, from both individual and social perspectives. We believe that a framework built upon social, artistic, and care-driven views of disability can account for the complexity of this activity and nourish further research into how different models of disability are integrated in the experience of people with aphasia.

Evaluation of Stackelberg Leader-Follower Interaction Between Policymakers in Small Open Economies
Authors: Tetik Metin , Ceylan Reşat
Published: October 2021

The problem of coordination between policymakers seems to have created fundamental problems related to economic and social costs, targeted inflation, potential growth, and a high budget deficit. To resolve these problems in this framework, it is important to see the results of the interaction between policymakers and to propose an optimal policy strategy. In this study, the interactions between monetary and fiscal policymakers are examined game theoretically within the framework of the New Keynesian model. The strategic interaction between these policymakers is assessed using the DSGE (Dynamic Stochastic General Equilibrium) model for a small open economy. From this point of view, the interaction between policymakers is assessed within the framework of hypothetical scenarios. The optimal monetary and fiscal policies for a small open economy are derived from the leader-follower mechanism solution known as the Stackelberg solution. Optimal Stackelberg policy rules derived for a small open economy contribute to the literature of economics. The performance of the game theoretically derived optimal policy rules is evaluated through dynamic simulation within the framework of counterfactual experiments. The parameters developed for the model are calibrated for the Turkish economy. Dynamic simulation of the models, the impulse response functions, and the social loss analysis shows that the optimal policy mix for the Turkish economy is when the monetary policymaker is the leader, and the fiscal policymaker is the follower.

Cushing’s disease is a chronic endogenous hypercortisolaemia associated with overproduction of adrenocorticotropic hormone by a pituitary adenoma, leading to multiple systemic complications that significantly increase morbidity and mortality, as well as reduce the quality of life as a result of prolonged tissue exposure to excess cortisol. Hypercortisolaemia in Cushing’s disease is associated with significant functional and constitutional disorders of the entire body. The consequences of chronic hypercortisolaemia include haemodynamic disorders associated with excessive vascular contraction and increased blood pressure, obesity, carbohydrate metabolism disorders, dyslipidaemia, and coagulopathies, which may contribute to significant cardiovascular remodelling. Cardiovascular disorders have a particular impact on long-term prognosis and quality of life in Cushing’s disease. If left untreated, Cushing’s disease significantly increases the cardiovascular risk and limits the treatment options for secondary organ complications. Cardiovascular mortality (myocardial infarction, heart failure, stroke) is several times higher in patients with Cushing’s disease than in the general population. Early diagnosis of the corticotropic pituitary tumour, as well as a thorough morphological and functional cardiovascular assessment seem essential in risk stratification. Normalisation of cortisol levels after combined neurosurgical and/or pharmacological treatment reduces mortality and the risk of cardiovascular and respiratory complications. The aim of this study is to present the complexity of clinical problems in patients with Cushing’s disease, who are in a particular need of interdisciplinary care.

Published: October 2021

In this research the effect of the addition of sea buckthorn puree (Hippophae rhamnoides L.) to goat cream butter was examined via analysis of its textural, physicochemical and sensory properties. Consumer acceptance was assessed. The addition of sea buckthorn promoted a stickiness and acidic flavour compared to the original goat butter. The number of consumers who liked goat butter increased by 35%. The optimal amount of sea buckthorn added was determined as 1.5%. A larger amount had a negative effect on the colour, as well as creating a more acidic flavour and fruit aroma.

Authors:   Agricultural University of Tirana, Faculty of Veterinary Medicine, Koder Kamez, 1029 Tirana, Albania, Lika Erinda
Published: October 2021

This research aimed to determine the prevalence rate of antimicrobial resistance (AMR) of Staphylococcus aureus isolated from raw cow milk samples in Albania and Serbia. A total of 100 raw milk samples, 50 from Albania and 50 from Serbia, have been collected from randomly selected cattle farms. Twelve samples (12%) were positive for S. aureus, five of those originating from Albania (41.66%) and seven from Serbia (58.33%). Resistance of isolated S. aureus strains to ampicillin in milk samples from Albania (36.7%) and Serbia (34.1%) was the most common. Some of S. aureus strains from milk samples from Albania were resistant to tetracycline (16.9%), while isolates from milk samples from Serbia were more resistant towards oxacillin (18%). The recorded resistance towards erythromycin (13.2%; 13.1%), and sulfatrim (7.6%; 6.9%) was similar between both milk samples, respectively. The obtained results have shown higher resistance of S. aureus strains towards cephalothin in milk samples from Serbia (3.9%) compared to milk samples from Albania (1.6%), respectively. All isolates tested for antibiotic sensitivity were susceptible to methicillin, vancomycin, chloramphenicol, and ciprofloxacin. The obtained results regarding the minimum inhibitory concentrations (MICs) of antibiotics indicated that isolates were resistant to tetracycline, oxacillin, erythromycin, and ampicillin, respectively. Results of our investigation have shown that the found antibiotics residues are related to the usage of erythromycin (72.6% and 73.9%), followed by ampicillin (70.4% and 71.2%) while residues of ciprofloxacin in the analysed milk samples was not registered.

Authors: Sompolska-Rzechuła Agnieszka
Published: October 2021

The aim of the article is to present the issues of choosing the optimal procedure for the linear ordering of objects and assessing the correctness of the selected methods of the linear ordering. The goal was achieved by creating linear ordering of objects using various methods for normalizing the value of diagnostic features. An aggregate measure based on various properties of the synthetic feature was used to select the optimal ordering, among others, the compatibility of the mapping, the correlation of the synthetic line variable with diagnostic variables, the rank correlation of the synthetic variable with diagnostic variables and the variability of the synthetic variable. The study was conducted based on the example of data concerning 28 European Union countries according to the level of socio-economic development in the context of sustainable development concerning society, economy and the environment. The linear ordering of countries using the quotient transformation with an arithmetic mean turned out to be the most correct ordering

RECENT RESULTS ON CARDINALITY ESTIMATION AND INFORMATION THEORETIC INEQUALITIES
Authors: Ngo Hung Q.
Published: October 2021

I would like to dedicate this little exposition to Prof. Phan Dinh Dieu, one of the giants and pioneers of Mathematics in Computer Science in Vietnam.
In the past 15 years or so, new and exciting connections between fundamental problems in database theory and information theory have emerged. There are several angles one can take to describe this connection. This paper takes one such angle, influenced by the author's own bias and research results. In particular, we will describe how the cardinality estimation problem -- a corner-stone problem for query optimizers -- is deeply connected to information theoretic inequalities. Furthermore, we explain how inequalities can also be used to derive a couple of classic geometric inequalities such as the Loomis-Whitney inequality.
A purpose of the article is to introduce the reader to these new connections, where theory and practice meet in a wonderful way. Another objective is to point the reader to a research area with many new open questions.
Job-shop Scheduling Over a Heterogeneous Platform
Authors: Benitez-Perez Hector , Hermosillo-Gomez Jose A.
Published: October 2021

Real-time scheduling involves determining the allocation of platform resources in such a way tasks can meet their temporal restrictions.

This work focuses on job-shop tasks model in which a task have a finite number of nonpreemptive different instances (jobs) that share a unique hard deadline and their time requirements are known until task arrival.

Non-preemptive scheduling is considered because this characteristic is widely used in industry. Besides job-shop scheduling has direct impacts on the production efficiency and costs of manufacturing systems. So that the development of analysis for tasks with these characteristics is necessary.

The aim of this work is to propose an online scheduling test able to guarantee the execution of a new arriving task, which is generated by human interaction with an embedded system, otherwise to discart it. An extension of the schedulability test proposed by Baruah in 2006 for non-preemptive periodic tasks over an identical platform is presented in this paper. Such extension is applied to non-preemptive tasks that have hard deadlines over a heterogeneous platform. To do that, some virtual changes over both the task set and the platform are effectuated.

Published: October 2021

Edge computing is difficult to deploy a complete and reliable security strategy due to its distributed computing architecture and inherent heterogeneity of equipment and limited resources. When malicious attacks occur, the loss will be immeasurable. RBF neural network has strong nonlinear representation ability and fast learning convergence speed, which is suitable for intrusion detection of edge detection industrial control network. In this paper, an improved RBF network intrusion detection model based on multi-algorithm fusion is proposed. kernel principal component analysis (KPCA) is used to extract data dimension and simplify data representation. Then subtractive clustering algorithm(SCM) and grey wolf algorithm(GWO) are used to jointly optimize RBF neural network parameters to avoid falling into local optimum, reduce the calculation of model training and improve the detection accuracy. The algorithm can better adapt to the edge computing platform with weak computing ability and bearing capacity, and realize real-time data analysis.The experimental results of BATADAL data set and Gas data set show that the accuracy of the algorithm is over 99% and the training time of larger samples is shortened by 50 times for BATADAL data set. The results show that the improved RBF network is effective in improving the convergence speed and accuracy in intrusion detection.

The results of the FGD, 4 super-categories and 13 sub-categories were derived and described as th following: “Making an effort, but the current system has limitations”, “Transition education support team: Let's evaluate properly, teach properly, and successfully do transition”, “Research cooperation support team: Educational research and student practice”, and “New wine for a new unit: Building a new school governance and democratic decision-making”. Based on the research results and discussion, the academic affairs-administrative organizational system of the affiliated special school was proposed with 4 teams and 13 departments. The Transition Education Support Team consisted of the Individual-Centered Transition Education Dept., Industry-Academic Cooperation Employment Support Dept., Career Counseling Dept., and three Major(Subject) Depts.. The Research Cooperation Support Team consisted of the Education and Research Dept., University-Linked Practice Support Dept., and Education and Information Dept.. The Student and Academic Affairs Support Team consisted of the Academic Affairs Support Dept., Student Government Dept., After-School Education Dept., and Dormitory Dept.. The Education Administration Team maintained the current administrative office work. Based on these research results, we suggested an organizational system model suitable for a vocational Special-Purpose Special School affiliated with a national university.
Prosperity, Gender Equality and Economic Development in the MENA Region
Authors: GÜLERYÜZ Ece Handan
Published: October 2021

In this study, the effects of macroeconomic fundamentals, prosperity, and gender equality factors on economic development are examined in 18 Middle East and North Africa (MENA) countries. Even though the MENA region countries have gone through advancements in the average wealth and prosperity levels in recent years, these positive changes have not been sufficient to prevent the region to fall behind other world regions in the rankings of development and economic growth. A panel data analysis is carried out for the time duration 2009 and 2019. This period coincides with both before and after the Arab Spring period. A wide spectrum of indicators is used to understand how different aspects of prosperity and gender equality can affect growth in the MENA region. In this way, a collective and comprehensive approach is adopted in the empirical analysis. One of the dependent variables, the productive capacity is calculated as a compound indicator which accounts for resource rents, GDP and working-age population. Two composite indicators, economic environment and institutions are used in the main estimations. Market access and infrastructure, investment environment, enterprise conditions, and economic quality are integrated to generate the variable economic environment. Governance, safety and security, and personal freedom are compounded to create the variable institutions. Later, these two composite indicators’ components are controlled individually in the estimations in order to carry out a robustness check analysis. It is found that female labor force participation, foreign direct investment, social capital, natural resource rents, education, a better economic environment, and improvements in safety-security can positively affect economic growth, total factor productivity and productive capacity. On the other hand, the overall quality of institutions and proportion of women representatives in national parliaments do not seem to significantly impact economic development in these MENA countries.
Party cues no Brasil? Um teste crucial da capacidade do sistema de partidos brasileiro em influenciar a opinião pública
Authors: Gramacho Wladimir
Published: October 2021

Resumo Este artigo apresenta um teste crucial da teoria das pistas partidárias ( party cues ) ao investigar a associação entre as posições legislativas do sistema de partidos políticos brasileiro, numa dimensão governo-oposição, e a avaliação governamental feita por seus simpatizantes. O contexto do teste é o governo Fernando Henrique Cardoso (1995-2002), marcado por sucessivas crises econômicas, o que tenderia a reduzir o poder de influência dos partidos sobre a opinião pública, frente ao tradicional poder explicativo das teorias do voto econômico e das funções de popularidade. Os resultados, baseados em modelos multiníveis a partir da análise de sete surveys , sugerem que as pistas partidárias funcionam inclusive num país como o Brasil e no contexto adverso escolhido nesse teste empírico. Os achados indicam ainda que as pistas partidárias são mais fortes segundo a relevância midiática de cada partido.
A influência de fatores demográficos e estruturais nos significados do trabalho entre brasileiros: evidências do World Values Survey
Authors: Satuf Cibele , Neves Jorge Alexandre Barbosa
Published: October 2021

Resumo O trabalho passou por transformações que modificaram os valores e determinantes de seus significados, colocando em xeque sua centralidade. Este artigo investiga os significados do trabalho entre brasileiros, bem como a influência de elementos demográficos e estruturais nessa atribuição. Os significados do trabalho referem-se à interpretação individual, influenciada pelo contexto social, do trabalho e do que ele representa. Utilizou-se a amostra brasileira do World Values Survey. A influência de características socioeconômicas e estruturais foi analisada via modelagens de equações estruturais (MEE). O modelo foi bem ajustado, tendo um coeficiente de determinação de 0,951. Os resultados descritivos indicaram alta valorização do trabalho e forte percepção deste como obrigação social. Os resultados da MEE indicaram que homens atribuem maior significado ao trabalho em comparação com mulheres e que o aumento da idade influencia a atribuição de significados do trabalho. A criatividade, a intelectualidade e a independência nas atividades executadas têm influência indireta (via nível socioeconômico - NSE) e negativa na percepção de significados do trabalho. As análises priorizaram a articulação entre aspectos sociais e econômicos com o processo de significação do trabalho, perspectiva pouco explorada na produção científica brasileira, mas fundamental para que o fenômeno seja compreendido de maneira mais ampla, especialmente em sociedades estratificadas, como o Brasil.
O bolso ou a ideologia? Determinantes da opinião dos brasileiros sobre globalização e livre comércio
Authors: Pinheiro Flávio , Fernandes Ivan Filipe , Almeida Maria Herminia Tavares de
Published: October 2021

Resumo O artigo discute os determinantes das opiniões dos brasileiros sobre a integração da economia brasileira aos mercados globais, analisando dados de survey nacional, realizado no âmbito do projeto “O Brasil, as Américas e o mundo”. Mostramos que os brasileiros, em boa medida, são favoráveis à abertura internacional de nossa economia e que suas atitudes são guiadas tanto por motivações econômicas como por ideias e valores políticos. A baixa exposição da economia brasileira à concorrência externa parece contribuir para a existência de opiniões favoráveis a maior acesso a bens importados. A posição ideológica, por sua vez, age como um filtro dessas percepções independentemente das condições econômicas dos indivíduos. Assim, evidências indicam que a posição do indivíduo como consumidor, sua ideologia política e suas visões nacionalistas influem em suas opiniões sobre globalização e livre comércio. Os resultados confirmam estudos anteriores sobre o mesmo tema feitos em países em desenvolvimento.
Movimentos sociais em interação com partidos políticos: a experiência do movimento ambientalista com o Partido dos Trabalhadores
Authors: Oliveira Marilia Silva de
Published: October 2021

Resumo O objetivo deste artigo é aproximar analiticamente duas literaturas que geralmente caminharam apartadas: a de movimentos sociais e a de partidos políticos. Propomos um debate sobre os processos de formação de identidade coletiva e de identidade partidária junto com elementos que definem a escolha de estratégia dos movimentos sociais e dos partidos políticos. Argumentamos que questões de identidade e de estratégia terão peso importante para estabelecer as interações entre movimentos sociais e partidos políticos e que tais interações podem ocorrer a partir da intermediação de lideranças sociopartidárias influentes tanto no campo social quanto no partidário. A discussão teórica foi desenvolvida com base em estudo de caso que observou a articulação de líderes do movimento ambientalista com partidos políticos, especialmente com o Partido dos Trabalhadores, desde a década de 1980 até o processo de formação da Rede Sustentabilidade. A intermediação da líder Marina Silva entre mundo social e mundo partidário foi fundamental para que lideranças do movimento ambientalista adentrassem os partidos políticos e suas arenas: legislativa, governamental e eleitoral. Concluímos que a relação prévia do movimento ambientalista com o Partido dos Trabalhadores foi crucial para a decisão de ambientalistas se engajarem na formação de um novo partido, a Rede Sustentabilidade.
Avaliar o quê? Os vários sentidos de efetividade no campo de estudos da participação
Authors: Martelli Carla Giani , Coelho Rony
Published: October 2021

Resumo O principal objetivo deste artigo é avançar na compreensão do termo efetividade utilizado pelo campo da participação para avaliar os resultados produzidos pelas instituições participativas. A revisão bibliográfica e a pesquisa com um corpus de 71 papers sobre a temática da efetividade da participação, apresentadas em quatro edições do “Encontro Internacional Participação, Democracia e Políticas Públicas”, mostraram a multiplicidade de sentidos que o termo pode assumir. Defendemos a ideia de que os trabalhos que se propõem a falar de efetividade devem definir com precisão o que pretendem avaliar, já que da clareza do objeto de avaliação dependem as conclusões sobre a validade dos espaços participativos e os estímulos necessários para sua continuidade.
