Creative problem solving and facial expressions: A stage based comparison
Authors: Kumar Mritunjay , Roy Satyaki , Bhushan Braj , Sameer Ahmed
Published: June 2022

A wealth of research indicates that emotions play an instrumental role in creative problem-solving. However, most of these studies have relied primarily on diary studies and self-report scales when measuring emotions during the creative processes. There has been a need to capture in-the-moment emotional experiences of individuals during the creative process using an automated emotion recognition tool. The experiment in this study examined the process-related difference between the creative problem solving (CPS) and simple problem solving (SPS) processes using protocol analysis and Markov’s chains. Further, this experiment introduced a novel method for measuring in-the-moment emotional experiences of individuals during the CPS and SPS processes using facial expressions and machine learning algorithms. The experiment described in this study employed 64 participants to solve different tasks while wearing camera-mounted headgear. Using retrospective analysis, the participants verbally reported their thoughts using video-stimulated recall. Our results indicate differences in the cognitive efforts spent at different stages during the CPS and SPS processes. We also found that most of the creative stages were associated with ambivalent emotions whereas the stage of block was associated with negative emotions.
Identification of sarcopenic obesity in adults undergoing orthopaedic surgery: Relationship between “a body shape index” (ABSI) and fat-free mass. A cross -sectional study

Published: June 2022

Background

Sarcopenic obesity is a condition characterised by the coexistence of low muscle mass and function (sarcopenia) and excessive fat mass (obesity). The aim of this study was to determine the prevalence of this condition in patients undergoing orthopaedic surgery by gender and type of orthopaedic surgery. In addition, this study investigated the suitability of a waist circumference-based anthropometric measure, body shape index (ABSI), for predicting sarcopenic obesity and the predictive power of ABSI for fat-free mass index (FFMI), a surrogate marker of lean body mass.

Methods and findings

A cross-sectional study of overweight and obese orthopaedic patients undergoing knee or hip and spine surgery was conducted between October 2019 and March 2020 in Orthopaedic Hospital Valdoltra, Slovenia. General anthropometric parameters body mass index (BMI) and ABSI = (WC/(BMI2/3x height½) as well as body composition data (fat mass FM, fat-free mass FFM, FFMI, and the ratio FM/FFM as an index of sarcopenic obesity) were determined in 120 women (aged 66.5 ± 9.6 years) and 89 men (aged 65.5 ± 7.8 years) with overweight (25 kg/m2 ≤ BMI < 30 kg/m2) and obesity (BMI ≥ 30 kg/m2) by bioelectrical impedance analysis (BIA). Sarcopenic obesity phenotypes based on FM/FFM ratio > 0.80 was present in 15.3% of patients, mainly in female patients undergoing knee surgery. ABSI was significantly associated with age in all women and obese men and with waist circumference (WC) in all patients. ABSI did not correlate with BMI in women and men; however, multiple linear regression analysis showed that BMI independently predicted FFMI (R = 0.83 and 0.70, respectively, p < 0.001) in women and men (β-coefficients: 0.801 and 0.686, respectively) and ABSI in women only (β-coefficient: -0.104). Women with a lower ABSI had a significantly higher FFMI than the group with a higher ABSI.

Conclusions

Sarcopenic obesity was most prevalent in obese women scheduled for knee surgery. In addition, ABSI, independently predicted FFMI in women and represents a significant predictor of sarcopenic obesity.
Pathways of school and community music: Towards lifelong musicianship
Authors: Bucura Elizabeth
Published: June 2022

In this article I survey ways community music (CM) and school music might be considered as related and connected pathways in individuals’ unique musical lives. School, while existing within communities, is considered a separate space for music teaching and learning, yet is one avenue by which musical participation can broadly occur within and among a variety of community spaces. Music teachers in schools can consider how the purposes and practices of CM might relate to goals of lifelong musicianship, thereby informing school music. I include background on CM and school music in the United States and discuss purposes that can underlie varied CM endeavours. I propose a loose definition for CM, provide examples and discuss differences among school music and CM leadership in each domain. I encourage broadened purposes for school music and an appeal to the human need for music, with a value for space to make one’s own meanings as music learners and, broadly, to engage with the world as musical people. When acknowledged by music educators as valid, purposeful and connected within as well as outside the classroom, CM can potentially become meaningfully connected to everyday lives in society, perhaps furthering the ways in which society regards musicianship.
Against all Odds: Forecasting Brazilian Presidential Elections in times of political disruption
Authors: Bertholini Frederico , Rennó Lucio , Turgeon Mathieu
Published: June 2022

When the number of observed elections is low, subnational data can be used to perform electoral forecasts. Turgeon and Rennó (2012) applied this solution and proposed three forecasting models to analyze Brazilian presidential elections (1994-2006). The models, adapted from forecasting models of American and French presidential elections, considers economic and political factors. We extend their analysis to the recent presidential elections in Brazil (2010, 2014 and 2018) and find that the addition of the three recent elections does not improve the accuracy of our forecast models although it strengthens the relationship between the explanatory variables and vote for the incumbent. We also find that models based on the popularity of the incumbent outperform those based on trial-heat polls and that electoral forecast models can survive earthquake elections like the 2018 election that led to the unexpected rise of “outsider” and extremist candidate Jair Bolsonaro.

O objetivo deste artigo é analisar a efetividade da participação popular nas audiências públicas virtuais a partir dos conceitos de legitimidade, prática social argumentativa e justiça. Para tanto, o artigo vale-se das ideias preconizadas por Neil MacCormick e Amartya Sen. Para atingir ao propósito desta pesquisa, apresentou-se, inicialmente, a função normativa da lei e a sua legitimidade. A partir destes conceitos, foi aberto espaço para se chegar ao pós-positivismo de Neil Maccormick e, assim, os limites do direito. Posteriormente, foi exposta a concepção de justiça de Sen, cujas atenções estão nas liberdades substantivas dos indivíduos. Na sequência, expõe-se o modelo de participação virtual que passou a ser utilizado de forma exclusiva pelo Poder Público no ambiente pós pandemia. Ao final, o trabalho sustenta que é necessário um avanço tecnológico no país a fim de que a participação popular nestas audiências seja, de fato, efetiva. É com base nesse contexto, mediante a utilização da metodologia bibliográfica e do método dedutivo, que se analisa as audiências públicas virtuais, as quais, em razão da limitação do seu acesso por condições econômicas e sociais, tem a igualdade de participação prejudicada, o que diretamente reflete na democracia e na justiça social.

Las universidades juegan un papel clave en la formación ambiental, definido en las agendas internacionales desde 1992. La Universidad José Antonio Páez, desde sus inicios ha considerado la educación ambiental en su currículo, como parte de la formación general del futuro profesional. La revisión documental sirve de base al presente trabajo, que da cuenta de su justificación de su inserción, desarrollo y de las expectativas en la formación ambiental de sus estudiantes.
Las universidades latinoamericanas en diálogo con la educación ambiental:
Authors: Hidalgo López Carelia Rayen
Published: June 2022

Desde el origen de la Educación Ambiental (EA), se realizó un llamado para su inserción en todos los espacios de la sociedad, incluyendo las universidades. Sin embargo, se observa un débil posicionamiento de la EA en las universidades y sus funciones sustantivas, pero si un creciente compromiso con el desarrollo sostenible o sustentable (DSS) y sus objetivos. Al reconocer el aumento, en las últimas décadas, del marco jurídico ambiental en Latinoamérica, qué tanto ha sido explicitada en estos la relación Universidad – EA, para avanzar desde la academia. Este estudio se realizó con análisis de contenido de las Leyes de Educación, Universidades, Educación Ambiental y Ambiente, conjuntamente con los planes o estrategias nacionales de EA, de 17 países. Los resultados muestran que 6 de ellos cuentan con una Ley de Educación Ambiental (Brasil, 1999; Honduras, 2009; Guatemala, 2010; Colombia, 2012; Panamá, 2014; y recientemente Argentina, 2021), y en 5 de esas leyes predomina la EA anclada al DSS, exceptuando en Brasil. Leyes que presentan inconsistencias discursivas en torno a los temas analizados, en un débil relacionamiento de la EA con las universidades. El joven campo interdisciplinario de la EA requiere fortalecerse en el abordaje complejo, inclusivo, crítico y transformador en los marcos legales y las políticas públicas, eso con la participación activa de las universidades a través de sus diversas funciones sustantivas.

Published: June 2022

A 16-year-old, 7.4 kg, castrated male Cocker Spaniel presenting anorexia and weight loss was referred due to a splenic mass, and total splenectomy was performed to resolve clinical signs. Following surgery, the dog developed mild hyperkalemia (6.27 mmol/L) without any clinical symptoms. Further investigations were conducted to determine the cause of hyperkalemia. The serum-plasma potassium difference was measured (1.05 mmol/L), and pseudohyperkalemia was diagnosed. The cause of pseudohyperkalemia was considered as thrombocytosis after splenectomy. The dog did not receive any specific treatment to lower blood potassium. To our knowledge, we report the first case of post-splenectomy pseudohyperkalemia in a dog.

This study aims to evaluate the Geography textbooks for the preparatory stage comprising the tenth, eleventh and twelfth grades and involving variables such as introduction, content, techniques, and activities. To this end, the researchers prepared a questionnaire; apparent validity and stability were determined by Alpha Cronbach. The questionnaire consists of (42) items, and for each item, there exists (3) choices, which are manifested by 'slightly agree', 'agree somehow', 'strongly agree' and the grades are (1), (2), (3) respectively. The questionnaire was administered to all members of the research community, who were (22) teachers. The results show that there are no statistically significant differences in the teachers' opinions according to the variables: gender, years of service, and the grade. They also reveal that teachers believe that Geography books for these grades do not appropriately match the level, and are therefore defective. Moreover, geographical books have many shortcomings, such as the lack of guidance for teachers, the lack of questions in the content, as well as the unattractive design...etc. The paper ends with the conclusions and recommendations.
Le lexique transdisciplinaire des écrits scientifiques dans les mémoires de diplôme des étudiants polonophones de français
Authors: Sowa Magdalena
Published: June 2022

The issue that we aim to investigate in this paper is related to the design of lexical resources which Polish university students use in the process of writing an academic text in French. In the course of the research, we concentrate on the transdisciplinary lexis composed of, on the one hand, cross-disciplinary terminology typical of scientific writings, and, on the other hand, of abstract, non-specialised vocabulary. In this regard, special focus is given to transdisciplinary collocations referring to scientific objects and procedures. The research is conducted on a corpus consisting of BA and MA theses written by Polish university students of French in Romance philology and applied linguistics faculties.The work progressed as follows. Firstly, the types of transdisciplinary collocations present in students’ theses were identified. They were then juxtaposed with the lexical resources gathered in the corpus of scientific texts in French (Corpus Écrits scientifiques en français). Finally, the manner in which students used the investigated collocations was analysed so as to identify the possible difficulties faced by non-native students of French. The objectives of this research are linguistic and didactic at the same time. Specifically, it aims to inventorystudents’ lexical resources, their scope and, as a result, to consider pedagogical solutions intended to enrich transdisciplinary vocabulary used in the process of writing scientific texts in university context. The analysis performed shows a weak presence of collocations containing scientific names. The students’ repertoire of lexical resources is relatively poor and not very varied. It is necessary to undertake more indepth work on the linguistic correction of the items mobilized.
Comment enseigner le discours scientifique en langue étrangère aux étudiants : la compétence discursive spécialisée à travers l’analyse des textes écrits
Authors: Bobowska-Nastarzewska Patrycja
Published: June 2022

The aim of the paper is to identify the methods of teaching academic discourse in French on the example of a selected written text whose subject matter is concerned with linguistics in connection with other disciplines. The analysis uses as its starting point the assumptions of the theory of the linguistic image of the world (J. Bartmiński) and of the cognitive linguistics (G. Lakoff and M. Johnson, R.W. Langacker) as applied in glottodidactics. While reading and understanding a written text, students activate the process of schematization (abstraction) and categorization/recategorization (R.W. Langacker). Teacher’s role is to explain specialized lexis to students and make an attempt with them to analyse scientific texts from an interdisciplinary perspective. It is also important to familiarize students with the editorial rules applicable to diploma dissertations, both bachelor’s and master’s in French as well as the criteria of textuality, in-cluding cohesion, coherence, intentionality, acceptability, informativity, situationality, and intertextuality (R.A. De Beaugrande, W.U. Dressler).

Data isolation has become an obstacle to scale up query processing over big data, since sharing raw data among data owners is often prohibitive due to security concerns. A promising solution is to perform secure queries over a federation of multiple data owners leveraging secure multi-party computation (SMC) techniques, as evidenced by recent federation work over relational data. However, existing solutions are highly inefficient on spatial queries due to excessive secure distance operations for query processing and their usage of general-purpose SMC libraries for secure operation implementation. In this paper, we propose Hu-Fu, the first system for efficient and secure spatial query processing on a data federation. The idea is to decompose the secure processing of a spatial query into as many plaintext operations and as few secure operations as possible, where fewer secure operators are involved and all secure operators are implemented dedicatedly. As a working system, Hu-Fu supports not only query input in native SQL, but also heterogeneous spatial databases (e.g., PostGIS, Simba, GeoMesa, and SpatialHadoop) at the backend. Extensive experiments show that Hu-Fu usually outperforms the state-of-the-arts in running time and communication cost while guaranteeing security.
In-network leaderless replication for distributed data stores
Authors: Kim Gyuyeong , Lee Wonjun
Published: June 2022

Leaderless replication allows any replica to handle any type of request to achieve read scalability and high availability for distributed data stores. However, this entails burdensome coordination overhead of replication protocols, degrading write throughput. In addition, the data store still requires coordination for membership changes, making it hard to resolve server failures quickly. To this end, we present NetLR, a replicated data store architecture that supports high performance, fault tolerance, and linearizability simultaneously. The key idea of NetLR is moving the entire replication functions into the network by leveraging the switch as an on-path in-network replication orchestrator. Specifically, NetLR performs consistency-aware read scheduling, high-performance write coordination, and active fault adaptation in the network switch. Our in-network replication eliminates inter-replica coordination for writes and membership changes, providing high write performance and fast failure handling. NetLR can be implemented using programmable switches at a line rate with only 5.68% of additional memory usage. We implement a prototype of NetLR on an Intel Tofino switch and conduct extensive testbed experiments. Our evaluation results show that NetLR is the only solution that achieves high throughput and low latency and is robust to server failures.
An in-depth study of continuous subgraph matching
Authors: Sun Xibo , Sun Shixuan , Luo Qiong , He Bingsheng
Published: June 2022

Continuous subgraph matching (CSM) algorithms find the occurrences of a given pattern on a stream of data graphs online. A number of incremental CSM algorithms have been proposed. However, a systematical study on these algorithms is missing to identify their advantages and disadvantages on a wide range of workloads. Therefore, we first propose to model CSM as incremental view maintenance (IVM) to capture the design space of existing algorithms. Then, we implement six representative CSM algorithms, including InclsoMatch, SJ-Tree, Graphflow, IEDyn, TurboFlux, and SymBi, in a common framework based on IVM. We further conduct extensive experiments to evaluate the overall performance of competing algorithms as well as study the effectiveness of individual techniques to pinpoint the key factors leading to the performance differences. We obtain the following new insights into the performance: (1) existing algorithms start the search from an edge in the query graph that maps to an updated data edge, potentially leading to many invalid partial results; (2) all matching orders are based on simple heuristics, which appear ineffective at times; (3) index updates dominate the query time on some queries; and (4) the algorithm with constant delay enumeration bears significant index update cost. Consequently, no algorithm dominate the others in all cases. Therefore, we give a few recommendations based on our experiment results. In particular, the SymBi index is useful for sparse queries or long running queries. The matching orders of IEDyn and TurboFlux work well on tree queries, those of Graphflow on dense queries or when both query and data graphs are sparse, and otherwise, we recommend SymBi's matching orders.

Serverless is a popular choice for cloud service architects because it can provide scalability and load-based billing with minimal developer effort. Functions-as-a-service (FaaS) are originally stateless, but emerging frameworks add stateful abstractions. For instance, the widely used Durable Functions (DF) allow developers to write advanced serverless applications, including reliable workflows and actors, in a programming language of choice. DF implicitly and continuosly persists the state and progress of applications, which greatly simplifies development, but can create an IOps bottleneck.

To improve efficiency, we introduce Netherite, a novel architecture for executing serverless workflows on an elastic cluster. Netherite groups the numerous application objects into a smaller number of partitions, and pipelines the state persistence of each partition. This improves latency and throughput, as it enables workflow steps to group commit, even if causally dependent. Moreover, Netherite leverages FASTER's hybrid log approach to support larger-than-memory application state, and to enable efficient partition movement between compute hosts.

Our evaluation shows that (a) Netherite achieves lower latency and higher throughput than the original DF engine, by more than an order of magnitude in some cases, and (b) that Netherite has lower latency than some commonly used alternatives, like AWS Step Functions or cloud storage triggers.
An I/O-efficient disk-based graph system for scalable second-order random walk of large graphs
Authors: Li Hongzheng , Shao Yingxia , Du Junping , Cui Bin , Chen Lei
Published: June 2022

Random walk is widely used in many graph analysis tasks, especially the first-order random walk. However, as a simplification of real-world problems, the first-order random walk is poor at modeling higher-order structures in the data. Recently, second-order random walk-based applications (e.g., Node2vec, Second-order PageRank) have become attractive. Due to the complexity of the second-order random walk models and memory limitations, it is not scalable to run second-order random walk-based applications on a single machine. Existing disk-based graph systems are only friendly to the first-order random walk models and suffer from expensive disk I/Os when executing the second-order random walks. This paper introduces an I/O-efficient disk-based graph system for the scalable second-order random walk of large graphs, called GraSorw. First, to eliminate massive light vertex I/Os, we develop a bi-block execution engine that converts random I/Os into sequential I/Os by applying a new triangular bi-block scheduling strategy, the bucket-based walk management, and the skewed walk storage. Second, to improve the I/O utilization, we design a learning-based block loading model to leverage the advantages of the full-load and on-demand load methods. Finally, we conducted extensive experiments on six large real datasets as well as several synthetic datasets.. The empirical results demonstrate that the end-to-end time cost of popular tasks in GraSorw is reduced by more than one order of magnitude compared to the existing disk-based graph systems.
DLCR

Published: June 2022

Many real-world graphs, e.g., social networks, biological networks, knowledge graphs, naturally come with edge-labels, with different labels representing different relationships between nodes. On such edge-labeled graphs, an important query is thelabel-constrained reachability (LCR)query, where we are given a sources, a targett, a label set ψ, and the goal is to check if there exists any pathPfromstotsuch that labels of edges onPall belong to ψ. Existing indexing schemes for LCR queries still focus on static graphs, despite the fact that many edge-labeled graphs are dynamic in nature.

Motivated by the limitations of existing solutions, we present a study on how to effectively maintain the indexing scheme on dynamic graphs. Our proposed approach is based on the state-of-the-art 2-hop index for LCR queries. In this paper, we present efficient algorithms for updating the index structure in response to dynamic edge insertions/deletions and demonstrate the correctness of our update algorithms. Following that, we present that adopting a query-friendly but update-unfriendly indexing scheme results in surprisingly superb query/update efficiency and outperforms those update-friendly ones. We analyze and demonstrate that the query-friendly indexing scheme actually achieves the same time complexity as those of update-friendly ones. Finally, we present the batched update algorithms where the updates may include multiple edge insertions/deletions. Extensive experiments show the effectiveness of the proposed update algorithms, query-friendly indexing scheme, and batched update algorithms.
An accurate but simple method for estimation of the influence of kerr nonlinearity on the far field pattern of LP11 mode in dispersion-shifted and dispersion-flattened fibers
Authors: Roy Kushal , Majumdar Angshuman , Gangopadhyay Sankar
Published: June 2022

In this paper, we have presented the far field pattern in presence and absence of Kerr type nonlinearity for the first higher order mode in Dispersion shifted and dispersion flattened type optical fibers. Our analytical results are based on simple power series expressions for the first higher order (LP11) mode of aforesaid fibers, which have been formulated by Chebyshev formalism. Using the analytical expressions for the linear case, method of iteration is applied in order to predict the concerned propagation parameters in presence of Kerr type nonlinearity. We have taken some typical trapezoidal index, step W and Parabolic W fibers for our study. Our results for the far field pattern have been shown to be in excellent agreement with the exact numerical results computed by rigorous finite element technique. The simplicity and accuracy of our formalism will prove helpful to the designers for setting up of efficient low dispersion optical link.

Published: June 2022

In this article, we model the current and voltage across the weak link between two superconductors. This gives us a nonhomogeneous, nonlinear parametric-driven sine-Gordon equation with phase shifts. This model equation cannot be solved directly but can be approximated. For the approximations, we use two methods, and analytic perturbation method and the numerical approximation method known as the Runge–Kutta method. For the analytic method, we construct a perturbation expansion method with multiple-scale expansion. We discuss the parametric-driven in the sine-Gordon equation with phase shifts for the 0–π–0 junction. Further, we also describe the breathing modes for various order of perturbation. At the end, we compare the solutions obtained via perturbation and numerical methods of parametric-driven sine-Gordon equation with phase shifts. Finally, we concluded that the modes of the breathing decay to a constant in both cases. Also we found a good agreement between both approximate methods.

Self-Monitoring of Damage Evolution in Asphalt Concrete Based on Electrical Resistance Change Method
Authors: Dong Zejiao , Ullah Shafi , Zhou Tao , Yang Chen , Luan Hai , Khan Rawid
Published: June 2022

Asphalt pavements expose early damage during their service life. The early damage grows internally until it accumulates and transforms into macro-damage that leads to structural failure. To promote real-time monitoring of internal damage evolution in asphalt pavements, this study proposes an electrical resistance change (ERC) method that exploits the piezoresistive properties of conductive asphalt concrete as a nondestructive testing technique capable of detecting microstructural defects. For this purpose, the traditional asphalt mixtures were first made electrically conductive by adding carbon fibers and iron tailing aggregates as conductive aggregates to satisfy the piezoresistivity requirements. Secondly, piezoresistivity experiments were performed by applying cyclic tensile force in fatigue and progressively increasing mode. The self-monitoring ability of damage evolution was assessed based on the correlation between the fractional change in electrical resistance (FCR), displacement, and damage degree for each mode of the force application. It was observed that under fatigue mode, the FCR and displacement increase upon loading and decrease reversibly upon unloading in each cycle. Compared with the displacement, the FCR exhibits partial reversibility upon unloading, indicating damage initiation in each cycle. The damage grows with the number of loading cycles until it accumulates in the elastic regime and gradually affects the load-carrying capacity of the mixture. Under a progressively increasing mode, the mixture exhibits a good correlation between the FCR and force in the elastic regime, ensuring real-time monitoring of internal micro-damage. However, the FCR develops a nonlinear correlation with the force in the inelastic regime that reflects damage to the conductive network and eventually structural failure. In summary, the ERC method provides real-time monitoring of microstructural defects that manifest as early damage and gradually transform into macro-damage under repeated traffic loads.

Published: June 2022

ΔfosB is an alternatively spliced product of the FosB gene that is essential for dopamine‐induced reward pathways and that acts as a master switch for addiction. However, the molecular mechanisms of its generation and regulation by dopamine signaling are unknown. Here, we report that dopamine D1 receptor signaling synergizes with the activin/ALK4/Smad3 pathway to potentiate the generation of ΔFosB mRNA in medium spiny neurons (MSNs) of the nucleus accumbens (NAc) via activation of the RNA‐binding protein PCBP1, a regulator of mRNA splicing. Concurrent activation of PCBP1 and Smad3 by D1 and ALK4 signaling induced their interaction, nuclear translocation, and binding to sequences in exon‐4 and intron‐4 of FosB mRNA. Ablation of either ALK4 or PCBP1 in MSNs impaired ΔFosB mRNA induction and nuclear translocation of ΔFosB protein in response to repeated co‐stimulation of D1 and ALK4 receptors. Finally, ALK4 is required in NAc MSNs of adult mice for behavioral sensitization to cocaine. These findings uncover an unexpected mechanism for ΔFosB generation and drug‐induced sensitization through convergent dopamine and ALK4 signaling.

Published: June 2022

The article provides information on the organization and functioning achievements of the Republican Arthrology Center (RAC), which has become the first specialized clinic in the Russian Soviet Federative Socialist Republic (RSFSR) that provided arthrological assistance to the population. The result of the organizational and methodological efforts of the RAC employees was the development of a network of rheumatology rooms in almost all territories of the country, along with the organization of the orthopedic rheumatology service and its separation from the cardiovascular rheumatology service. In the RAC, scientific developments were successfully carried out on the problems of arthroplasty of large joints, surgical and conservative treatment of patients with rheumatoid arthritis, osteoarthritis of large joints, prevention of contractures of the knee joint. Saratov Research Institute of Traumatology and Orthopedics (SRITO) hip joint endoprosthesis, a collapsible endoprosthesis and other constructions that have received wide recognition were created at the RAC. In the absence of international experience in creating an orthopedic rheumatology service network, the RAC was, on one hand, a pioneering phenomenon in world health care, and on the other hand, a natural consequence of the power vertical centralization in the USSR. At the same time, it should be emphasized that the need to create the RAC in the Russian Federation was caused by the growth in morbidity of rheumatic diseases, along with population aging and the prospects of orthopedic rheumatology associated, first of all, with the active introduction of total joint replacement with artificial structures in developed countries of the world. Over three decades of its existence, the RAC has been an organizational, methodological, medical, scientific and consulting center providing an orthopedic care to patients with diseases and injuries of large joints throughout the Russian Federation.

Published: June 2022

The objective was to evaluate the relationship between the patient neuropsychological condition and recovery of his/her motor activity disorder due to acute cerebrovascular accident.
Materials and Methods. The study involved 103 patients with ischemic stroke in the pools of middle and anterior cerebral arteries. We carried out clinical and neurological assessments of the patient condition, and conducted neuropsychological testing via Beck Hopelessness Scale (BHS), Montreal Cognitive Assessment (MоCA), SF-36, and Visual Analog Scale (VAS). The examination was performed on three occasions: during the acute phase of cerebral circulatory disorders, after two weeks and within the range of 24-36 months. After the long-term follow-up, all patients were distributed among two groups: with a favorable outcome and with unfavorable outcome. We attempted to identify the most typical values of above-mentioned scales for each group.
Results. The general physical health (GPhH) indicators based on the results of SF-36 (p=0.007), BHS (p=0.003 and 0.002), and VAS (p=0.025), collected after acute ischemic stroke, were prognostically significant. In both groups, the most important indicators for the stroke prognosis were MоCA (p=0.038), BHS (p=0.009) and SF-36 (GPH) (p=0.002), regardless of the stroke phase.
Conclusion. The connection between the patient neuropsychological condition and restoring the motor functions after the stroke was revealed. The investigated questionnaires can be included in the multivariate forecast model of the stroke prognosis among other criteria for the outcome of this disease.

In the context of criminal law, recognition of customary law begins with a very fundamental principle, namely the principle of legality – a legal basis for declaring an act as a criminal act. This paper examines the implementation of customary law regarding the violation of Penglipuran customary, in accordance with the customary delict from the perspective of the principle of legality and the future policy formulation of the principle of legality that accommodates the existence of customary law. To answer these problems, socio-legal research methods are used, data in the form of legal documents and results of in-depth interviews, various approaches (legal, theoretical, and historical approaches) and then analyzed through deductive-inductive methods. The results show that the Criminal Code adheres to the principle of formal legality, consequently, the written law is the only source to declare an act as an offense. Whereas in the Penglipuran community, it is known that customary delict is regulated not only in awig-awigbut also unwritten ones such as pararem penyahcah awig and perarem ngele. The existence of indigenous peoples is not only found textually but also commonly, carrying out their lives based on customary law which contains applicable values, principles, and norms. Therefore, it is necessary to formulate the principle of legality that accommodates the existence of customary law as a source of criminalizing acts. This is intended to realize a criminal law that accommodates the rights of indigenous peoples to “their own institutions, laws, and customs".
Between individual thinkers and women’s associations: an overview of the “female issue” during the first half of the French protectorate in Tunisia
Authors: Hernández-Justo Tatiana
Published: June 2022

In Tunisia, the role of pioneer of the feminist movement has often been granted to scholar Tahar al-Haddad, who wrote a very controversial book on women’s emancipation. However, he was not the first person to contribute to the “female issue”, as it came to be known. Other intellectuals had already been paving the way for reform and there were certain women’s associations working towards inclusion. In this paper, we will present an overview of the contribution that both individual thinkers and women’s associations made to the emancipation of women during the first half of the French protectorate in Tunisia.

Deconstrucción de la identidad nacional sionista: las raíces ideológicas de la expulsión de los árabes
Authors: Castillo Manteca Jose Manuel
Published: June 2022

Este artículo analiza el conflicto israelí-palestino desde la visión de la psicología social y la historia de las ideas políticas sionistas. Se trata para ello de hacer una deconstrucción de la identidad nacional sionista, deconstruyendo los principales mitos y narraciones que posibilitaron establecer una conexión nacional entre las tierras palestinas y el futuro Estado judío. A continuación, mediante las propias declaraciones y planes de los principales líderes sionistas, se tratará de demostrar que dicho proyecto nacional suponía inevitablemente la expulsión de la población árabe local, iniciando así lo que es un problema de carácter colonial que aún hoy persiste.
