As arqueologias afetivas na produção discente da Universidade Federal do Vale do São Francisco: desdobramentos históricos e interfaces teóricas na construção da Arqueologia no Sudeste e Sudoeste do Piauí
Authors: Mageste Leandro Elias , Amaral Alencar de Miranda
Published: July 2022

Resumo No presente artigo, analisamos a construção da Arqueologia no sudeste e sudoeste do Piauí, no intuito de explicitar as condições e os desdobramentos que têm configurado um conjunto de práticas arqueológicas assentadas na interface entre ciência e afeto. Tratam-se das ‘arqueologias afetivas’, que podem ser identificadas em processos socialmente engajados de produção de conhecimento, catalisadas nos contextos dinâmicos de interações que foram constituídos no semiárido. Para concretização desse propósito, consideramos desde o início dos trabalhos arqueológicos que culminaram na criação do Parque Nacional Serra da Capivara, na década de 1970, até os eventos mais recentes, representados pela inserção da Arqueologia na expansão do ensino superior, com a criação do curso de Arqueologia e Preservação Patrimonial, na Universidade Federal do Vale do São Francisco (UNIVASF), em São Raimundo Nonato, a partir de 2004. Nesse exercício, verificamos algumas sobreposições de cenários e, ao mesmo tempo, explicitamos as transversalidades com posicionamentos teóricos, metodológicos e políticos que se projetam a partir da realidade latino-americana.

Determination of the coefficient of consolidation by piezocone tests under partially drained conditions
Authors: Liu Kehan , Wang Dong , Zheng Jingbin
Published: July 2022

Dissipation tests after piezocone penetration are used widely to estimate the consolidation behaviour of cohesive soils. Interpretation of dissipation tests is complicated in intermediate soils, such as in silts and silty clays, since the accumulated pore pressures and the subsequent dissipation response are affected by the partially drained conditions. The influence of partial drainage on dissipation response is investigated using a large-deformation finite-element approach within the framework of effective stress analysis. The numerical approach is validated by comparison with the existing centrifuge tests where dissipation tests were performed after undrained and partially drained penetrations. The numerical results provide insights to quantify the effects of drainage conditions, including distribution of pore pressures prior to dissipation and then the operative coefficient of consolidation, ch, against various penetration velocities. The time corresponding to a given degree of dissipation is found to be increased with reducing normalised penetration velocity, as the gradients of normalised pore pressures are reduced in the radial direction before dissipation. The ratio between ch and the coefficient of consolidation can be described through a unique backbone curve. A new approach estimating the coefficient of consolidation from a dissipation test following partially drained penetration is proposed for practical applications.
Efficiency of GFRP Reinforcement in Concrete Columns having Hybrid Fibers: Experiments and Finite Element Analysis
Authors: Raza Ali , Khan Qaiser uz Zaman
Published: July 2022

This investigation explores the structural performance of glass fiber reinforced polymer (GFRP) reinforced concrete columns incorporating hybrid fibers (GHFRC columns) under different loading conditions. The hybrid fiber reinforced concrete (HFRC) consisted of two kinds of fibers (steel, SF and polypropylene, PF). A total of nine GHFRC specimens with a diameter of 250 mm and a height of 1150 mm were fabricated and tested to failure. A 3D finite element model (FEM) was developed for the GHFRC specimens using ABAQUS 6.14. The definition of HFRC was performed using an improved concrete damaged plasticity model and the definition of GFRP material was performed by using a linear elastic model. The test results revealed that the ductility of GHFRC columns was improved with the reduction in the ligature spacing. The columns eccentricity showed higher ductility indices than concentric columns. The loading eccentricity resulted in a substantial decrease in the axial strength (AS) of GHFRC columns. The close correlation between tests and FEM results validate the applicability of FEM. A mathematical model was suggested for predicting the AS of GHFRC specimens by taking into account the axial influence of GFRP bars and the confining influence of GFRP ties.

Purpose Scholars have been interested in intrapreneurship in recent years, but there is no unified definition of intrapreneurship, and scholars have not proposed a unified standard for intrapreneurship terms. Given these problems, the objective of this study was to determine the current state of intrapreneurship based on a literature analysis and the problems that exist in the research, as well as to provide new directions for future research. Design/Methodology/Approach First, we examined 291 studies by year of publication, author, research field, journal, and journal type through the Web of Science (WOS) database. We also look into the issues of specialization and sustainability in intrapreneurship research by conducting research into authors and research areas. Second, we analyzed publishing periodicals to look into how it developed in the field of knowledge. Third, we identified the types of databases used in intrapreneurship research by taking into account the data sources utilized in all empirical studies in our survey. Finally, from the concept of intrapreneurship, we summarize its concept based on three different terms: corporate entrepreneurship, intrapreneurship, and corporate venturing, and explore the differences. From a comprehensive perspective, we focused on examining the use of intrapreneurship terms through a review of the literature. Findings In this paper, we examine the overall research trend of intrapreneurship and discover that the frequency of term use has changed over time. why it has changed? And what is the cause of this change? These are the areas that we believe we will be able to research in the future. Furthermore, we discovered that different terms have different definitions, and while there are similarities and differences between terms, there is no clear definition of their differences in current research and internal entrepreneurship. These findings contribute to the development of a research agenda for the future. Research Implications The background of term use and the unclear distinction between terms presented in this study provide some hints for future research. Practically, by organizing the definitions of intrapreneurship terms in this study, scholars will have a clear sense of boundaries in their use of intrapreneurship terms, which will increase their attention to the background of intrapreneurship terms. Furthermore, by compiling the literature in this paper, we can identify the problems in current research and serve as a guide for scholars’ future research directions.

Authors:   The Korea International Trade Research Institute, Choi Sung-Kwang , Ha Myung-Shin
Published: July 2022

Purpose The purpose of this study is to analyze the relationship between conflict response, social capital, and supply chain integration in the supply chain of the shipping port logistics industry by dividing it into leading and participating companies. Design/Methodology/Approach The measurement items were constructed based on previous studies, the confirmatory factor analysis was performed using the AMOS 18 to evaluate the reliability and validity and the fit of the measurement model. The results of this study are as follows. Findings First, it was found that the avoidance conflict response of leading and participating companies did not have a significant effect on social capital and supply chain integration. Second, it was found that the cooperative conflict response between leading companies and participating companies had a significant positive (+) effect on social capital and a significant positive (+) effect on supply chain integration. In addition, it was found that social capital had a significant positive (+) effect on supply chain integration in both leading and participating companies. Research Implications Avoiding avoidance conflict response and using cooperative conflict response can strengthen the competitiveness of the supply chain through the establishment of social capital such as mutual benefit, trust, and value sharing in a rapidly changing global logistics environment, and further increase the level of supply chain integration and performance.

Authors:   The Korea International Trade Research Institute, Jeong Jong-Hee , Kim Senog-Ho
Published: July 2022

Purpose This study examines multi-dimensional determinants affecting SCM 4.0, and identifies whether innovation orientation plays a role as a mediator between these exogenous variables and SCM 4.0. In addition, this study recognizes whether SCM 4.0 influences Korean export SME operational performance. Design/Methodology/Approach Drawing on the comprehensive perspective in TOE, DOI, and dynamic capability theory, this study hypothesizes that technological uncertainty and the relative advantage of ICT are positively related to innovation orientation as mediating variables between these exogenous variables and SCM 4.0, and leading to performance. Data were obtained through a survey sent to export manufacturing SMEs in Busan and Gyoungnam in Korea. Findings The results suggest that all exogenous variables are mostly significantly related to SCM 4.0. Also, innovation orientation as mediating variables is statistically significant between these exogenous variables and SCM 4.0. In addition, results show that SCM 4.0 influences SMEs operational performance positively. This is a reason for SMEs to implement SCM 4.0. Research Implications This study agrees with the findings of antecedents affirming that SCM 4.0 positively influences a firm’s operational performance primarily by possessing the innovation orientation of the organization. Finally, this study suggests that implementing SCM 4.0 in SMEs may increase a sustainable competitive advantage in a dynamic global SCM environment and corporate value in a long-term perspective.

Published: July 2022

Purpose This study attempted to analyze the competitiveness of the three major ports, Shanghai Port, Ningbo-Zhoushan Port, and Lianyungang Port, and put forward policy implications for the development of the ports in the Yangtze River Delta to enlighten the development of port logistics in South Korea and propose the possibility of cooperation between South Korean and Chinese ports. Design/Methodology/Approach In this study, two influencing factors were analyzed by deriving the sub-factors of four determinants of Porter’s diamond model, and the competitiveness of port logistics in the Yangtze Delta in China was analyzed using the Regional Innovation System (RIS) model. Findings Through the analysis of each representative port in the Yangtze Delta region, the overall competitiveness of port logistics is in relatively good condition. Except for the relatively low logistics competitiveness of ports such as the Lianyun River Port, most ports, including Shanghai Port and Ningbo-Zhou San Port, are already high. Research Implications First, it is necessary to establish a diversified cooperative system for the distribution of port logistics between Korea and China. Second, it is indispensable to take full advantage of a policy to revitalize regional ports at a national level. Third, it is necessary to continue to expand the industrial supply network and ties in the port hinterland of the Yangtze River Delta region of China. Fourth, it is necessary to identify the strengths and weaknesses of the regional innovation system and establish a business strategy for port logistics toward China.
The Endogenous Formation of Intellectual Property Protection Mechanism
Authors:   The Korea International Trade Research Institute, Lee Yoo-Hwan , Kim Sang-Kee
Published: July 2022

Purpose This study studies the conditions for the endogenous intellectual property protection(IPP). Design/Methodology/Approach Based on the research and development (R&D) spillover model by d’Aspremont and Jacquemin (1988), the analytical framework of this study is set up. Findings For a given low IPP cost and large R&D spillover to make IPP highly efficient, instead of choosing “no use of the mechanism”, the firms optimally choose “use the mechanism”. In this situation, the profits is worse off, which is a clear case of prisoner’s dilemma. In contrast, for a given high IPP cost that makes IPP inefficient, each firm has an incentive to choose the strategy of “no use of the mechanism”. Research Implications Our finding does not support the public-generating a large volume of domestic IPP. In some countries, the government-supported policies to drive firms to create greater intellectual property rights have been widely established. If the polices reduce IPP costs, the distortion in producer surplus will be larger.
The Effects of Monetary Policy and Tax Policy on Housing Prices in Korea
Authors:   The Korea International Trade Research Institute, Jo Gab-Je
Published: July 2022

Purpose This paper investigates the effects of monetary policy and capital gains tax policy on housing prices in Korea. Design/Methodology/Approach The study employed SVAR (Structural Vector autoregression) based the impulse response function as well as the variance decomposition analysis. Findings According to the results of the impulse response function, it was found that the interest rates, reflecting Korea’s monetary policy, have had significantly decreasing effects on housing prices. On the other hand, the stricter policy of capital gains taxes have shown significantly increasing effects on housing prices. Research Implications Thus, this study suggests that, in order to achieve financial stability in addition to inflation stability, the central bank needs to consider housing prices in a monetary policy framework. Also, this study implies that even stricter policies for capital gains taxes could result in instability in housing prices through a lock-in effect in the housing supply.

Purpose The purpose of this paper is to analyze the effects of the psychological ownership of employees on organizational citizenship behavior as an organizational effectiveness and how do team-member exchange and perceived team support have moderating effects on the relationship between psychological ownership and organizational effectiveness. Design/Methodology/Approach Based on a survey method, the empirical analysis sampled 435 employees working at 5 MNC subsidiaries in South Korea. With the hierarchical regression analysis, all hypotheses were tested and supported. Findings This paper shows that the higher the psychological ownership, the greater the positive effects on the organizational citizenship behavior and it also reveals that organizational effectiveness could be affected by employee’s psychological ownership level. Team-member exchange and perceived team support have moderating effects on the relationship between psychological ownership and organizational citizenship behavior. Research Implications In the management of this paper, this study shows that an employee’s psychological status has an importance to explain their behavior and it should be recognized that the behaviors are affected by organizational context variables, at the team level, such as team-member exchanges and perceived team support.

An Analysis of the Interest Rate Risk of the Federal Reserve’s Balance Sheet, Part 1: Background and Historical Perspective
Authors: Anderson Alyssa , Na Dave , Schlusche Bernd , Senyuz Zeynep
Published: July 2022

As part of its implementation of monetary policy, the Federal Reserve (Fed) holds Treasury securities and agency mortgage-backed securities (MBS) in the System Open Market Account (SOMA). The market value of these securities and the Fed's income fluctuate with changes in interest rates. As such, the ongoing increases in policy rates to address inflationary pressures are expected to put downward pressure on the Fed's net income.
SONOMA: a Small Open ecoNOmy for MAcrofinance
Authors: Croce Mariano Massimiliano , Jahan-Parvar Mohammad R. , Rosen Samuel
Published: July 2022

We develop a new small open economy model (SONOMA) in which domestic corporate debt and equities are affected by shocks to both external credit and equity markets. In a novel empirical analysis of several small-but-developed economies, we show that both external debt and equity shocks are important determinants of domestic economic fluctuations, corporate leverage, and net foreign asset positions. SONOMA replicates our empirical facts about asset prices, financial flows, and economic activity.

Published: July 2022

Foreign trade, affected by digitalisation, acquired new features, while its development led to a new redistribution of world regions. The present article aims to reveal specific features and emerging trends in the digital segment of foreign trade and identify leading regions and success factors. In this case, the digital segment includes ICT-equipment and ICT-services trade. UNCTAD statistics for 2000–2019 were examined using the methodology of foreign trade structural and comparative analysis. We hypothesise that there are different development stages in the digital segment of foreign trade characterised by changes of leading regions. In particular, three waves in the development of the digital segment of foreign trade, corresponding to different characteristics, were identified. In the third wave, the growth rate of digital turnover remained the same but its share in the total global turnover decreased. It was revealed that the share of the digital segment is higher than the share of merchandise trade in the countries of one region. Asia-Pacific Region replaced the USA (that moved from the 1st place in the first wave to the 5th position) as the leading region. China, specialising in the export of ICT-equipment, came out on top with the 27.1 % share of digital exports in the country’s total exports, increasing by 15.9 times in 20 years. Russia, whose specialisation is the export of ICT-services, is closer to the end of the top 50 ranking of countries in this segment; its negative foreign trade balance was also revealed. The obtained findings can be useful for specialists developing the foreign digital trade strategy of Russia. In order to increase the potential of national economies, including Russia, in the digital segment of foreign trade, further research should focus on ways to prevent their lagging behind the leaders.

Published: July 2022

Over the past decades, the process of knowledge generation has accelerated, producing a lot of scientific publications, which makes reviewing even a relatively narrow subject area very demanding, if not impossible. However, recent text data mining tools can assist researchers in conducting such analysis in an objective and time-efficient way. We conduct such a literature review on 1307 articles published in the journal Economy of Regions from 2010 to 2021 using advanced topic modelling techniques. This analysis aims to describe the main research areas in the journal over time, the dynamics of their popularity and the relationship with key quantitative indicators. We identified 22 topics ranging from “Agriculture” and “Economic Geography” to “Fiscal Policy” and “Entrepreneurship”. We estimate how popularity of these topics was changing over time and find topics that gained the most popularity from 2010 to 2021 (+17.61 %, “Spatial Economics”) or lost it (-14.58 %, “Economics of Innovation”). The topic of environmental economics collects the largest number of citations per article (3.64, on average), and the topics on monetary policy and poverty are the most popular among manuscripts in English, which is also true for articles written by authors with foreign affiliation. Papers with third-party funding are concentrated the most in “Spatial Economics” (around 11 %), and the least — in “Agriculture”. Our results can help to understand the evolution in scope of research of Economy of Regions and serve researchers to find promising directions for future studies.

Published: July 2022

The Russian economy is emerging, meaning that natural resources play a dominant role in economic development. Given the considerable volatility in resource prices, we investigate the volatility spillovers among policy uncertainty, international oil prices, exchange rate, stock index and metal prices covering the period of 2 July 2008 to 15 May 2020 for the Russian economy applying Dynamic Connectedness based on Time-Varying Parameter Vector Autoregression (TVP-VAR). Our empirical investigation demonstrates that gold price, Russian policy uncertainty, oil price and stock index are net volatility contributors, whereas palladium, platinum, silver and exchange rate are net volatilities receivers. Market capitalisation and silver market are found to be the highest net contributor and net receiver, respectively. The palladium appears as a net volatility receiver initially, just after the global financial crisis. The Russian economic policy uncertainty appears to be the dominant volatility contributor from 2008 to 2014, but onward it turned to be a net volatility receiver. Over the year 2014, gold price was the prominent volatility contributor to another market when the oil price dropped significantly. The total connectivity of the markets are highly anchored with several exogenous shocks, including economic sanction, adoption of floating exchange rate, oil price plunge. Our empirical findings provide several policy implications to portfolio managers and Russian regional stakeholders.
Assessment of the Socio-Ecological and Economic Welfare of the Russian Eastern Regions Using Sen’s Extended Function
Authors:   Institute of Natural Resources, Ecology and Cryology of the Siberian Branch of RAS, Zabelina I. A.
Published: July 2022

The accelerated development of the Russian Far East is among the country’s national priorities. Since the ultimate goal is to increase the well-being of the population, it is important to create a healthy environment. The article presents the comprehensive assessment results of the welfare of the Eastern regions in the context of achieving the strategic goals of the state policy for the development of the Russian Far East. The research aims to assess the character of socio-economic development, as well as to obtain quantitative characteristics of socio-ecological and economic well-being of the Eastern regions using a multiplicative model based on Sen’s extended welfare function. It is hypothesised that environmental factors play an important role in the quality of life in the Eastern regions, meaning that the inclusion of the corresponding component in the multiplicative model will lead to a decrease in the assessment of their welfare. For some regions, the study identified such negative trends as the strengthening of the raw material orientation of economic development, a decrease in the share of manufacturing industries, continuing resource export. The inclusion of the environmental component into the multiplicative model significantly affected the assessment results: in most of the Eastern regions, environmentally adjusted characteristic of regional development was significantly lower than the indicator that does not consider this aspect. Moreover, some border regions showed the worst dynamics of the examined indicators. Advantages of the border situation and accelerated development mechanisms currently implemented in the Far East have not yet contributed to a noticeable increase in the welfare of these regions. The research results can be used in the public administration practice for developing strategic planning documents, socio-economic and environmental programmes, as well as for evaluating the effectiveness of implemented accelerated development mechanisms.

Authors: GÜNGÖR KOBAT Sabiha , CEM GÜL Fatih
Published: July 2022

Objective: The aim of this study was to evaluate the changes in refraction values in children receiving online education because of the COVID-19 pandemic. Material and Methods: Fifty-six patients under the age of 18 who received distance education during the pandemic period, had at least 6 hours of screen exposure and were prescribed spectacles were included in the study. Visual acuity was measured with Snellen Chart. The refraction values seen by the patient were recorded and his records were scanned retrospectively. Refraction values in 2020 were compared with refraction values in 2018 and 2019. A value of p<0.05 was considered statistically significant.Results: The mean age of the patients was 14.23±3.17 years. The mean refraction values of the patients in 2020 were -2.69±1.37 D in the right eye and -2.63±1.01 D in the left eye. The mean refraction values in 2019 were -2.17±1.10 D in the right eye and -2.00±1.23 D in the left eye. Mean refraction values of the patients in 2018 were -1.54±1.22 D in the right eye and -1.42±1.18 D in the left eye. The average refraction values of the patients in both eyes in 2020 were significantly higher compared to 2019, and the average refraction values in 2019 were significantly higher than in 2018 (p<0.001, p<0.001). Refraction increase during the pandemic period was similar to the previous year (right: p=0.48, left: p=0.94).Conclusion: In our study, we found a significant increase in the mean refraction values of myopic children who receiving online education due to the pandemic and had intense screen exposure, and this increase was similar to the previous year. We think that this situation is caused by the unconscious long-term use of electronic devices such as smartphones, computers and tablets in addition to the online education during the pandemic period, the decrease in time spent outside and the long-term close work.

Published: July 2022

Background: Controversy continues in the treatment decisions despite advanced imaging techniques. Though specific diagnosis by imaging is not precise. Diffusion weighted imaging is useful in a small proportion of patients. We evaluated the features of magnetic resonance imaging (MRI) with histopathological findings in patients with lesions of the cavernous sinus (CS). Materials and methods: Retrospective analysis of clinical, imaging and histopathological findings of lesions involving cavernous sinus (CS) in 27 consecutive patients was done. Results: The average age of the study population was 41.12 ± 14.49 (13-63) years; with 16 (59.2%) males. Visual disturbances were the most common complaints, reported in 62.0% and cranial nerve involvement was observed in 55 % of the patients. Complete excision was done in nine (33.3%) patients. Post-operative histopathology revealed meningiomas and hemangiomas in six (22.2%) patients each. While, five (18.5%) patients had schwannoma; fungal granuloma was observed in three (11.1%). Imaging based diagnosis showed concordance with histopathology in five (85.0%) patients with hemangioma. Among fungal granuloma, schwannoma and meningiomas, the concordance was 66.6%, 40.0% and 33.3% respectively. In the entire study population, concordance was 44.4%. Conclusions: MR signal intensities are similar in neoplasms, infections, vascular lesions and inflammatory lesions. Cavernous hemangiomas are most often mistaken for other lesions but may be characterized by intense contrast enhancement and absence of restriction of DWI and blooming on GRE sequence. In lesions of cavernous sinus, accuracy of diagnosis on MRI is less than 50%. Diagnosis on MRI is more accurate in hemangiomas and fungal granulomas. Non-invasive diagnosis of granulomatous lesions may help plan appropriate management strategy. Keywords: cavernous sinus; magnetic resonance imaging; diffusion weighted imaging

Purpose: The present study aimed to evaluate and estimate the additional and auxiliary diagnostic value of routine laboratory parameters in patients with acute diarrhea caused by rotavirus and adenovirus. Methods/ patients: A total of 6784 patients diagnosed with acute gastroenteritis were evaluated. Rotavirus and adenovirus infection was diagnosed via a Qualitative immunochromatographic combo rapid cassette antigen test. Complete blood count and biochemical blood tests were performed in all the patients and were compared between the groups according to the positivity or negativity of the virus. Results: Rotavirus diarrhea was diagnosed in 16.8% and adenovirus diarrhea in 3.2% of patients. Hemoglobin, hematocrit, and mean cell volume (MCV) levels were lower, and aspartate aminotransferase (AST) and alanine aminotransferase (ALT) levels were significantly higher in rotavirus positive cases. Neutrophil to lymphocyte ratio was significantly higher, and lymphocyte to monocyte ratio was significantly lower in positive rotavirus cases than negative ones 2.96 and 2.56, respectively (p<0.001). Conclusions: Hematological and biochemical parameters may assist in diagnosing and distinguishing rotaviral and adenoviral gastroenteritis, especially in low-resource environments.

Implementing Enhanced MIMO with F-OFDM to Increase System Efficiency for Future 5G Cellular Networks

Published: July 2022

The upcoming fifth generation of cellular communication system is most likely to be deployed by the year 2020. The new generation of mobile network is expected to have high data rates, low latency and support a huge number of devices. Aside from this, machine type communication (MTC) and internet of things (IoT) are expected to be handled by 5G system in a better and efficient way. For this reason, a number of waveform candidates have been proposed. Filtered orthogonal frequency division multiplexing (F-OFDM) is one of the proposed candidates for 5G systems, which highly resembles to its predecessor that is orthogonal frequency division multiplexing (OFDM). The crucial difference between the two multicarrier waveforms is the use of a well-designed filter. F-OFDM in comparison with OFDM thus provides reduced out of band emission, which enables it to utilize the allocated spectrum efficiently. This research paper provides a brief review of F-OFDM performance with multiple input multiple output (MIMO) implementation. Using MATLAB, the MIMO system with F-OFDM has been tested for different configurations such as SIMO (receive diversity) and MISO (transmit diversity) with different digital modulation schemes including QPSK, 16-QAM, 64-QAM and 256-QAM. The bit error rate (BER) vs the signal to noise ratio (SNR) plots judge the performance of the system.
Local Self-government in the System of Civil Society Institutions

Changes in public relations and a high level of civic engagement have led to the constitutional amendment and adoption of such categories as civil society and institutions of civil society. An important result of constitutional modernization was the normative consolidation in the text of the Constitution of the Russian Federation of the main forms of interaction between civil society institutions and public authorities. For the implementation of the constitutional provisions, it is necessary to develop theoretical ideas concerning the activities of the structural elements of modern society on their interrelations with public authorities.

The legal characteristics of a civil society institution are studied in the context of local self-government. It is opined that local self-government is not even remotely qualified to be regarded an institution of civil society because it lacks the attributes of independence and autonomy of activity. In accordance with the legislation of the Russian Federation, a significant part of the activities of local self-government bodies, including their formation, takes place in the public sphere. Only certain elements of their activities in particular, the forms of direct democracy can be attributed to the sphere of civil society. It is suggested that local self-government be considered from the general law view as a form of interaction between civil society institutions and the public authorities.

Special attention is paid to the relationship between local self-government and civil society. An analysis of the current regulations on the interaction between civil society institutions and local self-government bodies leads to the conclusion that the existing legislation does not fully provide for the implementation of various forms of direct participation of citizens and their associations in the local self-government affairs. Therefore, it is necessary to improve legislation in order to increase the effectiveness of the interactions between local self-government bodies and civil society institutions.
A framework for measuring and mitigating bias in electronic health record data

Electronic Health Records (EHRs) are valuable sources of healthcare data with tremendous potential to improve patient care and reduce financial costs. Advanced data mining and analytical methods are necessary to obtain, transform, and analyze EHR data for secondary uses such as clinical and health policy research, and machine learning methods are key to addressing challenges in secondary EHR uses. However, developing machine learning models equitably is a significant challenge. As machine learning tools become more ubiquitous in healthcare research and clinical practice, it is critical that predictive models are developed that work to alleviate, rather than exacerbate, existing disparities in the healthcare system. Bias may be introduced into a machine learning model through the data used to train the model, algorithm selection, or in how a model is implemented in an applied setting. In this work, we present a framework for assessing and alleviating bias in dataset development for a classification model derived from EHR data. Classification, which refers to inputting observations from data into categories, is a common machine learning task and a method that is increasingly used in medical research. Classification may be used to predict future health outcomes, identify patients who are at risk for developing a condition, and to make clinical diagnoses. In this work, we present a case study in childhood obesity incidence prediction where a classification model is developed that aims to predict future obesity among pediatric patients based on demographic data and the presence of clinical diagnostic patterns in their medical history. We use easily accessible EHR data that may be obtained to predict other outcomes of interest, and present a method to evaluate data to develop classifiers that may be used for prediction of other chronic diseases (such as heart disease, diabetes, and asthma). First, temporal pattern mining is applied to EHR data to identify common diagnostic patterns that surround pediatric obesity incidence. Next, a dataset is developed for the study cohort, that indicates whether or not patients had the temporal condition patterns that were previously identified and demographic information (such as race/ethnicity, gender, etc.) obtained from their EHR. Then, classification models are trained and tested using this dataset. We develop a framework for assessing bias in EHR-derived datasets, and present its application in our pediatric obesity incidence case study. We conclude by discussing implications of our work in healthcare research and outlining directions for future research, including assessing and alleviating bias in algorithm selection and model development.
Dropout and rearrest

Published: July 2022

Youth with individualized education plans (IEPs) and youth of color experience disproportionate rates of exclusionary discipline, school dropout, and arrest each year. However, it is unclear how these factors relate, especially among justice-involved youth. This study furthers existing research by examining IEP status, race, suspension, permanent school removal, school dropout, and recidivism among youth arrested in schools. Additionally, this study explored the potential predictive role of IEP classification type on school dropout and recidivism. Results indicated that Black students with IEPs who had previously been arrested were at higher risk for recidivism than their justice-involved peers. Exploratory results also revealed that students with different IEP classifications dropped out of school and were rearrested at different rates, and rates for rearrest differed by students' race. These results have implications for school interventions to attenuate initial justice system referrals and for broader justice system changes to address racial and disability disparities.
Performance of the Female

This thesis seeks to explore the virtual YouTuber (vtuber) phenomenon, focusing on the visual design and exploring how the feminine form is represented in these avatars. This was achieved through research on how the interactions between users are mediated by digital avatars and connecting vtubers to existing frameworks such as performing femininity, affective economics, and digital third places. In addition, interviews with vtubers were conducted to gather first-hand knowledge on vtubers. The research investigated what personality and visual features attracted viewers and held sustained engagement, as well as looked for potential existing trends that inspired the appearances of vtubers. a survey was conducted to gather the opinions of viewers and vtubers. After this, the data was analysis and used in part to create an "idealized vtuber." While not a perfect model, it was created to start conversations on what makes a vtuber gain viewership. The research was inconclusive. There appears to be a diverse range of opinions on what is preferred in an entertainer, both visually and in content. In addition, became clear that there is no one way of performing femininity, rather, a vtuber can performer their version of femininity, and then the audience creates assumptions about the vtuber that reinforces that femininity. The survey indicated that there may be a connection to having a likeable personality and being popular, but what type of personality does well is inconclusive. What can assist in being successful is having a model that has distinct eyes that catch a viewer's attention, and then surrounding those eyes with expressions. There appeared to be no indication that existing trends inspired appearance in vtubers. The responses to the survey varied widely, indicating that self-expression was more important that following a particular trend.
