Plantar fasciitis (PF) is common among both sports and inactive individuals and several treatment approaches are available. There is no study that examines the effect of massage on PF in multi-discipline athletes such as modern pentathletes. This study evaluated the effectiveness of massage on modern pentathletes suffering from PF. Twelve male athletes between the ages of 18 and 25 who had a history of plantar fasciitis pain and participated in modern pentathlon sports took part in the study. Every athlete received a 15-minute deep friction massage (DFM) between 13:00 and 17:00 on each day of the week for 15 days. Before and after the massage, all athletes' pain and endurance levels were measured. For pain assessments, pressure pain algometry was utilised, and for endurance evaluations, the yo-yo intermittent endurance test was utilised. Athletes participating in the study before (3.5 (2-5)) and after (7 (6-8)) pain average measurements and before massage (830±60) and after (1498.33±52.88) endurance average measurements pretest-post It was determined that there was a statistically significant difference between test values. According to the study, massage, an alternative therapeutic strategy, can be used to address the PF issue. To increase the accuracy of the findings and to assert that massage is the definitive treatment for PF, it is proposed that other sample groups with PF diagnoses be included in the studies, or that the treatment time for a single sample group be extended.

Bu çalışmanın amacı, tenis hakemlerinin psikolojik sağlamlık düzeyleri ile sürekli kaygı düzeyleri arısındaki ilişkinin incelenmesidir. Araştırmaya 72’si kadın, 149’u erkek olmak üzere toplam 221 tenis hakemi katılmıştır. Araştırmada veri toplama amacıyla hakemlere “Kişisel Bilgi Formu”, “Kısa Psikolojik Sağlamlık Ölçeği” ve “Sürekli Kaygı Ölçeği” uygulanmıştır. Verilerin analizinde ikili gruplar için t testi, ikiden fazla gruplar için ise tek yönlü varyans analizi ve Scheffe (post-hoc) kullanılmıştır. Sürekli kaygı ve psikolojik sağlamlık düzeyi ile ilgili çeşitli değişkenlere göre (yaş, eğitim durumu, hakemlik kategorisi, hakemlik süresi ve çalışılan turnuva sayısı) yapılan analizlerde istatistiksel olarak anlamlı fark bulunamamıştır. Araştırma sonucunda tenis hakemlerinin psikolojik sağlamlıkları ile sürekli kaygı düzeyleri arasında negatif yönde orta düzeyde bir ilişki bulunmuştur. Araştırma sonuçlarına göre tenis hakemlerinin psikolojik sağlamlık düzeyleri arttıkça sürekli kaygı düzeyleri azalmaktadır denilebilir. Psikolojilerini sağlam tutmak ve kaygı düzeylerini kontrol edebilmek hakemler için çok önemlidir. Bu konuda federasyonlar tarafından düzenlenecek seminerler ve eğitimlerde uzman kişiler eşliğinde, dünya çapında düzenlenen diğer turnuvalarda yaşanan olaylar video sunumları ile gösterilerek ve çözümler konuşularak hakemlerin kaygı ve stres düzeylerini nasıl kontrol altında tutacakları ile ilgili katkı sağlanabilir.

İşitme engeli olan bireylerin psikomotor becerileri ve bilişsel becerilerinin akranlarına göre geride kaldığı bilinmektedir. Bu sebeple, işitme engelli öğrencilerin günlük yaşam becerilerinin iyileştirilmesinde kullanılacak spor eğitim programları önem arz etmektedir. Bu araştırma işitme engelli öğrencilere uygulanan oryantiring eğitim programının bilişsel ve motor becerilerine etkisini incelemek amacıyla yapılmıştır. Çalışma grubu 52 işitme engelli ortaöğretim düzeyindeki öğrenciden oluşturulmuştur. Kontrol grubunun yaş ortalaması 18,23± 1,30 yıl (n=26) olan, deney grubunun 18,38±1,20 yıl (n=26)’dır. Oryantiring eğitim programı 16 hafta süre ile deney grubuna uygulanmış, bu sürede kontrol grubuna eğitim uygulanmamıştır. Tüm katılımcılara eğitime başlanılmadan önce ve sonrasında bilişsel ve motor beceri ölçümleri yapılmıştır. İstatistik analiz sonuçları incelendiğinde, deney grubunun bilişsel becerilerden konsantrasyon, dikkat, seçici dikkat ve görsel bellek; motor becerilerden ise çeviklik (“T” drill, 505 çeviklik, altıgen engel, yan-yön), denge (dinamik denge, kapalı ve açık göz denge duruşu), kuvvet (duvar squat duruşu ve sıçrama), esneklik (gövde-boyun statik esneklik) ön ve son test puanları karşılaştırıldığında pozitif yönlü anlamlılık bulunmuştur (p<0.01). Kontrol grubunda ise seçici dikkat ve öğrenme güçlüğü puanlarında anlamlı iyileşme tespit edilmiştir (p<0.05). Sonuç olarak, orta öğretim düzeyinde olan işitme engelli öğrencilere uygulanan 16 haftalık oryantiring eğitim programının kontrol grubuna göre bilişsel ve motor beceriler üzerinde daha fazla pozitif etkisi olduğu söylenebilir. Oryantiring sporunun işitme engelli öğrencilerin eğitim programları içerisine dahil edilmesi önerilmektedir.
Organizational justice and quality of work life in hotels: The mediating effect of trust climate
Authors: Akter Kaniz Marium , Tang Swee Mei , Adnan Zurina
Published: March 2023

The study aimed to investigate the impact of hotels' organizational justice (OJ) on the quality of employees' work life (QWL), with the mediation effect of teams' climate of trust (CT). Social Exchange Theory was employed to support the research framework. Data were collected using 281 questionnaires from the operational employees of 3-star hotels in Bangladesh and assessed by SPSS version 21 and SmartPLS 3.0 software. Data were validated by a measurement model and hypotheses were tested by a structural model using the PLS-SEM approach. The study discovered significant effects of hotels’ organizational justice (β=0.271) and team’s climate of trust (β=0.362) on employees’ quality of work life (R2=27.7%). It also reveals the effect of the hotel's OJ (β=0.369) on teams’ CT (R2=13.6%), and a partial mediation effect of team's CT (β=0.134) in the relationship between the hotel's OJ and employees' QWL. Results indicate that hotels' organizational justice practices enrich employees' quality of work life and nurture mutual trust among the team members, while a team's climate of trust can convert hotels' organizational justice into employees' quality of work life. These findings would inspire the hotel authorities in practicing organizational justice to develop a trusting climate in the working teams, and designing QWL programs for attaining employee satisfaction. The study was limited to the Bangladesh hotel industry which restricts the generalizability of its results.
An Introduction to Music Theory
Authors: Gyebi - Tweneboah Kwasi
Published: March 2023

Hefler and Przybylek (2022) defined music theory as the sound that has been creatively organized. They further went on to state that “music theory involves various fundamentals such as melody, texture, rhythm, pitch, keys and clef.”[1] Music theory can also be defined as the building block of music. This book deals with the different components that combine to make good music. Although the theory found in this book has its principle in Western art music, the principles can be applied to other forms of music. In order to appreciate music theory, the author has added a music theory practice book. This book is to be used with the theory practice book for more work.

We derive the spatial and wavelength behavior of dust attenuation in the multiple-armed spiral galaxy VV 191b using backlighting by the superimposed elliptical system VV 191a in a pair with an exceptionally favorable geometry for this measurement. Imaging using the James Webb Space Telescope and Hubble Space Telescope spans the wavelength range 0.3–4.5 μm with high angular resolution, tracing the dust in detail from 0.6–1.5 μm. Distinct dust lanes continue well beyond the bright spiral arms, and trace a complex web, with a very sharp radial cutoff near 1.7 Petrosian radii. We present attenuation profiles and coverage statistics in each band at radii 14–21 kpc. We derive the attenuation law with wavelength; the data both within and between the dust lanes clearly favor a stronger reddening behavior (R = A

Dynamics of Four Triple Systems
Authors: Tokovinin Andrei
Published: March 2023

Orbital motions in four hierarchical stellar systems discovered by speckle interferometry are studied. Their inner orbits are relatively well constrained, while the long outer orbits are less certain. The eccentric and misaligned inner orbits in the early-type hierarchies ϵ Cha (B9V, central star of the 5 Myr old association, P = 6.4 yr, e = 0.73) and I 385 (A0V, P ∼ 300 yr, e ∼ 0.8) suggest past dynamical interactions. Their nearly equal masses could be explained by a dynamical decay of a 2+2 quadruple progenitor consisting of four similar stars. However, there is no evidence of the associated recoil, so similar masses could be just a consequence of accretion from the same core. The other two hiearchies, HIP 32475 (F0IV, inner period 12.2 yr) and HIP 42910 (K7V, inner period 6.8 yr), have smaller masses and are double twins where both inner and outer mass ratios are close to one. A double twin could either result from a merger of one inner pair in a 2+2 quadruple or can be formed by a successive fragmentation followed by accretion.
Boundary Layers of Circumplanetary Disks around Spinning Planets. I. Effects of Rossby Waves
Authors: Fu 付 Zhihao 智豪 , Huang 黄 Shunquan 顺权 , Yu 余 Cong 聪
Published: March 2023

Gas giant planets are believed to accrete from their circumplanetary disks (CPDs). The CPDs usually involve accretion through the boundary layer (BL) in the vicinity of planets. Prior studies have concentrated on the BL of nonspinning planets. We investigate the influence of planetary spin on the wave behaviors within the BL. The rotation profile in such BLs would show a sharp transition from the rigid rotation to the Keplerian rotation. We examine the angular momentum transport in these BLs in terms of linear perturbation analysis. We find that the global inertia-acoustic mode associated with spinning planets would give rise to the inflow of angular momentum and the accretion of gas. In this work, we identify a new kind of global mode, namely the Rossby mode. The Rossby mode can lead to the outflow of angular momentum and the decretion of gas from a spinning planet. The Rossby mode provides a negative feedback that regulates the planetary spin and mass. We compare the growth rate of the two modes as a function of the width of BL, the Mach number, and the spin rate of planets. Our results reveal the underlying hydrodynamic mechanism of terminal spins and asymptotic mass of the giant planets.
Comparison of the Composition of ICMEs from Active Regions and Quiet-Sun Regions

Published: March 2023

The composition of interplanetary coronal mass ejections (ICMEs), including the ionic charge states and elemental abundances of heavy elements, is tightly correlated with their source regions and eruption processes. This can help in analyzing the eruption mechanisms and plasma origins of CMEs, and deepen our understanding of energetic solar activities. The active regions and quiet-Sun regions have different physical properties; thus, from a statistical point of view, ICMEs originating from the two types of regions should exhibit different compositional characteristics. To demonstrate the differences comprehensively, we conduct survey studies on the ionic charge states of five elements (Mg, Fe, Si, C, and O) and the relative abundances of six elements (Mg/O, Fe/O, Si/O, C/O, Ne/O, and He/O) within ICMEs from 1998 February to 2011 August using data from the Advanced Composition Explorer. The results show that ICMEs from active regions have higher ionic charge states and relative abundances than those from quiet-Sun regions. For the active-region ICMEs, we further analyze the relations between their composition and flare class, and find a positive relationship between them, i.e., the higher the classes of the associated flares, the larger the means of the ionic charge states and relative abundances (except the C/O) within ICMEs. As more (less) fractions of ICMEs originate from active regions around the solar maximum (minimum), and active-region ICMEs usually are associated with higher-class flares, our studies might answer why the composition of ICMEs measured near 1 au exhibits a solar cycle dependence.

We present the Transiting Exoplanet Survey Satellite (TESS) light curve of GRB 230307A. We find two distinct components: a bright, prompt optical component at the time of the Fermi observation that peaked at TESS magnitude 14.49 ± 0.05 (averaged over 200 s), followed by a gradual rise and fall over 0.5 day, likely associated with the afterglow, that peaked at 17.65 ± 0.06 mag. The prompt component is observed in a single 200 s Full Frame Image and was undetectable in the next TESS image (T
mag > 17.79). Assuming that the onset of the optical transient was coincident with the gamma-ray emission, the prompt emission lasted less than 73.6 s, which implies the true peak was actually brighter than T
mag = 13.40. We also fit parametric models to the afterglow to characterize its shape. The TESS TICA light curve can be retrieved at https://tess.mit.edu/public/tesstransients/light_curves/lc_grb230307A_cleaned.txt.

Published: March 2023

The light curve of Gaia23bab (=SPICY 97589) shows two significant (ΔG > 2 mag) brightening events, one in 2017 and an ongoing event starting in 2022. The source’s quiescent spectral energy distribution indicates an embedded (A

V
 > 5 mag) pre-main-sequence star, with optical accretion emission and mid-infrared disk emission. This characterization is supported by the source’s membership in an embedded cluster in the star-forming cloud DOBASHI 1604 at a distance of 900 ± 45 pc. Thus, the brightening events are probable accretion outbursts, likely of EX Lup-type.
Modeling the Formation of Selk Impact Crater on Titan: Implications for Dragonfly

Published: March 2023

Selk crater is an ∼80 km diameter impact crater on the Saturnian icy satellite Titan. Melt pools associated with impact craters like Selk provide environments where liquid water and organics can mix and produce biomolecules like amino acids. It is partly for this reason that the Selk region has been selected as the area that NASA’s Dragonfly mission will explore and address one of its primary goals: to search for biological signatures on Titan. Here we simulate Selk-sized impact craters on Titan to better understand the formation of Selk and its melt pool. We consider several structures for the icy target material by changing the thickness of the methane clathrate layer, which has a substantial effect on the target thermal structure and crater formation. Our numerical results show that a 4 km diameter impactor produces a Selk-sized crater when 5–15 km thick methane clathrate layers are considered. We confirm the production of melt pools in these cases and find that the melt volumes are similar regardless of methane clathrate layer thickness. The distribution of the melted material, however, is sensitive to the thickness of the methane clathrate layer. In the case of a 10–15 km thick methane clathrate layer, the melt pool appears as a torus-like shape that is a few kilometers deep, and as a shallower layer in the case of a 5 km thick clathrate layer. Melt pools of this thickness may take tens of thousands of years to freeze, allowing more time for complex organics to form.

Sea cucumbers (holothuroids) play a major role in coastal environments; their detritivore conduct favors oxygen penetration in the sediments and the disposal of pathogens on the sea floor. This study determined holothuroid diversity in the rocky intertidal zone of Matanchén Bay, Mexico. Sampling campaigns were carried out in January, March, May, and July 2018. Linear transects (10 m length and 1 m width) perpendicular to the coastline in rocky areas (0-3 m depth) were established, where the density (ind m-2) and proportion (%) of sea cucumbers were estimated. Organisms were photographed, examined live, and preserved in 70% alcohol for subsequent identification utilizing ossicle characterization. Our results show the presence of four sea cucumber species: Holothuria (Halodeima) inornata Semper, 1868, Holothuria (Selenkothuria) lubrica Selenka, 1867, Holothuria (Selenkothuria) portovallartensis Caso, 1954, and Holothuria (Mertensiothuria) viridiaurantia Borrero-Pérez & Vanegas-González, 2019. The average density per species was 0.208, 0.108, 0.017, and 0.025 ind m-2) and proportion (%) of sea cucumbers were estimated. Organisms were photographed, examined live, and , respectively; each species' proportion was 58.1, 30.2, 4.7, and 7.0%, respectively. Due to the above values, we found that the number and spatial distribution of sea cucumber species vary in Matanchén Bay.

The effect of live yeast Rhodoturula glutinis was evaluated on juvenile Oreochromis niloticus cultivated in a Biofloc system. Growth performance and the expression of innate response and relevant oxidative stress genes were evaluated after a 12-week feeding trial. Three experimental treatments were evaluated in a conventional tilapia culture (control), Biofloc culture (BFT), and Biofloc with the addition of the live yeast R. glutinis 1×106 CFU g-1 (BFT+Rg), with four replicates per treatment. In all cases, commercial food was supplied to the organisms (32% protein and 5% lipids). O. niloticus juveniles (7.02 ± 0.04 g) were randomly distributed in 12 tanks, each with 15 animals. BFT+Rg treatment showed a significant increase in weight gain compared with the other treatments. Significant improvements were found in Fulton's condition factor, feed conversion rate, and hepatosomatic index under Biofloc conditions, BFT, and BFT+Rg treatments. No significant differences were observed in survival. R. glutinis directly influenced gene expression in the liver and intestine. The expression of tnfa, tgfb, hsp70, and gpx, genes in the liver significantly increased in the BFT+Rg treatment compared with the other treatments. Similarly, a significant increase was found in intestinal il1b, tnfa, tgfb, trf, hsp70 gpx, and cat expression patterns in the BFT+Rg treatment. Based on the performance and immune response, the present study suggests the use of R. glutinis as a strategy to increase the productivity of tilapia in Biofloc culture.

Published: March 2023

Aquaculture combines techniques for breeding and harvesting aquatic organisms used in shrimp production. It is important as a source of income and for generating foreign exchange in the regions where it is practiced. However, the timely detection of diseases continues to be a great challenge for aquaculture and fisheries production. In recent years, Enterocytozoon hepatopenaei (EHP) has emerged as a major pathogen of the Pacific white shrimp Penaeus vannamei in many Asian countries (Vietnam, China, Indonesia, Malaysia, Thailand, India, and Korea). In Latin America, only in Venezuela, and to date, there is no report of its presence in Mexico. It is transmitted directly from shrimp to shrimp by oral or fecal means, cannibalism, or exposure to contaminated water. Hepatopancreatic microsporidiosis (HPM) is mainly associated with stunted growth and severe infections that can cause a poor production cycle, mortality, and problems in larva-producing laboratories. This review aims to overview the main microsporidian parasites and diseases found in white shrimp, including the clinical signs, control and prevention measures for EHP infection, and the detection of HPM using different techniques. In order to offer timely detection tools, different techniques are available for the detection and study of microsporidia. Such as optical microscopy, transmission electron microscopy, and histology; however, for diagnostic purposes, molecular methods are preferred due to their sensitivity, specificity, and short-time analysis. Our review suggests that constant monitoring in shrimp hatcheries and farms is essential to avoid the entry or transference of infected organisms, affecting shrimp production and the ideal development of healthy shrimp.

This study aimed to evaluate the development and the increase in the skin pigmentation of the organism Heros severus cultured in a biofloc system with diets enriched with carotenoid pigments. The culture was made in 80 L water tanks with 20 juvenile organisms of H. severus; each treatment was made by duplicate. Four experimental diets were used: a) trout feed, El Pedregal®; b) TetraColor®; c) carrot and d) beetroot. The diet that obtained the highest values regarding the growth of the fish was the control diet. Regarding the coloration of the fish, the beetroot diet was the diet that presented the highest values with 9.55 μg of total carotenoids in tissue, presenting significant differences (P = 0.001) concerning the other diets, proving that a diet based on beetroot can be a good option for the culture of ornamental fish. Because it allows the organisms to have a survival rate above 90%, have similar growth to the control group, and a significant improvement in coloration, being a natural carotenoid low-cost source to improve the commercialization of organisms. Nevertheless, it did not present significant differences (P = 0.005) regarding beetroot and TetraColor® diets, while it presented significant differences with the carrot diet.

Environmental temperature can act as a positive or negative modulator of the physiology and metabolism of poikilothermic organisms. As a general rule, larvae and juveniles are more sensitive to temperature stress than adults, which represents a key factor that partly determines their development and growth in aquaculture. Therefore, this study analyzed the effect of exposure to temperatures of 21, 24, and 27°C on the respiratory metabolism (RM) of Totoaba macdonaldi in different developmental stages. For this purpose, eggs, larvae with 4, 6, 8, 14, and 22 days post-hatch (dph), and juveniles of 25 dph were exposed to the experimental temperatures for 5 h. After the exposure time, oxygen consumption measurements were performed. The results clearly show that temperature (21 to 27°C) has the greatest effect on RM in eggs and larvae at 4 and 22 dph (3.1 ± 0.3 to 4.3 ± 0.3 μmol O2 h-1 egg-1, 2.9 ± 0.3 to 10.5 ± 1.2 μmol O2 h-1 larvae-1 and 102.0 ± 6.4 to 189.8 ± 15.3 μmol O2 h-1 larvae-1, respectively). This thermal sensitivity was not observed from 6, 8, and 14 dph larvae and juveniles at 25 dph, where morphological development was the main factor that influencing the RM. Therefore, this study shows that temperature affects RM in different development stages of totoaba, beginning in the egg stage and intensifying once the larvae hatch until 22 dph. Understanding how temperature affects energy expenditure by measuring RM is essential to establish culture conditions that allow better physiological performance and growth in the early life stages of T. macdonaldi.

Gender differences in time taken for peer review and publishing output in the physical sciences
Authors: Leedham Elvidge Emma C.
Published: March 2023

Background: Despite decades of work to improve gender equality in science (and other science, technology, engineering, and maths fields), gender bias still exists and has been shown to impact the retention of women in academic scientific careers. Publication of peer-reviewed articles remains a key criterion for career progression and a common marker of success in academia. Any barriers to publication faced by women may therefore impact their retention and career progression.

Objectives: To investigate gender differences within one potential barrier to publication, namely the time taken in peer review, by investigating the question: ‘Is the peer review process longer for papers with (assumed) women as first authors than those with (assumed) male first authors?’

Methods: Gender differences in peer review time were analysed for 1100 peer-reviewed papers published between 2006 and 2016 and selected from 5 journals covering a range of physical science disciplines and publication styles.

Results: In the physical sciences, male first-authored papers outnumbered female first-authored papers 2:1. However, the analysis showed no statistical difference in the time taken for peer review between the two sets of papers.

Conclusion: The time taken to peer review a paper is not linked to the gender of the paper’s first author. However, the large discrepancy in the number of papers with men as first authors compared to that with women as first authors could be a contributing factor to the attrition of women from the academic career ladder (the so-called ‘leaky pipeline’).
Body size and body condition in the nose-horned viper (Vipera ammodytes): effects of sex and populations
Authors: Čubrić Tijana , Bonnet Xavier , Crnobrnja‐Isailović Jelka
Published: March 2023

Snakes are ecologically and morphologically plastic organisms that exhibit extensive variations in body size and body condition in response to environmental factors. Documenting inter-population variations is important to describe species comprehensively across their distribution range and to monitor trends over time (e.g. decreasing body condition due to alteration of habitat). Thus, we analyzed the influence of population and sex on body size and body condition in three populations of nose-horned vipers (Vipera ammodytes) in Serbia. In one population, males were larger than females (F1, 39=4.802, p=0.034), but not in the two other populations (F1, 36=0.075, p=0.786; F1, 21=0.018, p=0.893). Females exhibited higher body condition (residual values from the regression of log-body mass against log-body size) than males (F1, 90=10.444, p=0.002); this sex difference was not found in one population when analyzed separately (F1, 35=1.834, p=0.184). Moreover, we found strong inter-population differences in mean body size and mean body condition (F2, 96=8.822, p<0.001 and F2, 90=10.319, p=0.001, respectively). While inter-population difference in body size was driven by males, inter-population difference in body condition was driven by females. These results suggest that, in this species, body size might be an important determinant of mating success in males, while body condition may play a major role in female fecundity.

Dear Readers, 

It gives me great pleasure to announce the third regular issue of 2023. In this issue, 4 papers by 11 authors from 5 countries cover various topical aspects of computer science. In an ongoing effort to further strengthen our journal, I would like to expand the editorial board: If you are a tenured associate professor or above with a strong publication record, you are welcome to apply to join our editorial board. We are also interested in high-quality proposals for special issues on new topics and trends. 

As always, I would like to thank all the authors for their sound research and the editorial board for their extremely valuable review effort and suggestions for improvement. These contributions, together with the generous support of the consortium members, sustain the quality of our journal. 

In the third regular issue, I am very pleased to introduce the following 4 accepted articles: Gerardo Matturro from Uruguay reports on his research findings on undergraduate software engineering over a seven-year period, specifically on students' motivation to participate in research projects, skills acquired, and their perceptions of benefits. Uma Priya D and P. Santhi Thilagam from India propose an approach to cluster heterogeneous JSON documents using the similarity fusion method based on structural, semantic and contextual measures of JSON schemas. Zeinab Rahimi and Mehrnoush Shamsfard from Iran present a hybrid contradiction detection approach that can detect seven categories of contradictions in Persian texts: Antonymy, negation, numerical, factive, structural, lexical and world knowledge, which is based on a novel data mining method and a transformer-based deep neural method for contradiction detection. In their joint research between Estonia, Spain and India, Shashi Kant Shankar, Adolfo Ruiz-Calleja, Luis P.

Multimodal Learning Analytics (MMLA) solutions aim to provide a more holistic picture of a learning situation by processing multimodal educational data. Considering contextual information of a learning situation is known to help in providing more relevant outputs to educational stakeholders. However, most of the MMLA solutions are still in prototyping phase and dealing with different dimensions of an authentic MMLA situation that involve multiple cross-disciplinary stakeholders like teachers, researchers, and developers. One of the reasons behind still being in prototyping phase of the development lifecycle is related to the challenges that software developers face at different levels in developing context-aware MMLA solutions. In this paper, we identify the requirements and propose a data infrastructure called CIMLA. It includes different data processing components following a standard data processing pipeline and considers contextual information following a data structure. It has been evaluated in three authentic MMLA scenarios involving different cross-disciplinary stakeholders following the Software Architecture Analysis Method. Its fitness was analyzed in each of the three scenarios and developers were interviewed to assess whether it meets functional and non-functional requirements. Results showed that CIMLA supports modularity in developing context-aware MMLA solutions and each of its modules can be reused with required modifications in the development of other solutions. In the future, the current involvement of a developer in customizing the configuration file to consider contextual information can be investigated.
Leveraging Structural and Semantic Measures for JSON Document Clustering
Authors: Priya D Uma , Thilagam P. Santhi
Published: March 2023

In recent years, the increased use of smart devices and digital business opportunities has generated massive heterogeneous JSON data daily, making efficient data storage and management more difficult. Existing research uses different similarity metrics and clusters the documents to support the above tasks effectively. However, extant approaches have focused on either structural or semantic similarity of schemas. As JSON documents are application-specific, differently annotated JSON schemas are not only structurally heterogeneous but also differ by the context of the JSON attributes. Therefore, there is a need to consider the structural, semantic, and contextual properties of JSON schemas to perform meaningful clustering of JSON documents. This work proposes an approach to cluster heterogeneous JSON documents using the similarity fusion method. The similarity fusion matrix is constructed using structural, semantic, and contextual measures of JSON schemas. The experimental results demonstrate that the proposed approach outperforms the existing approaches significantly. 
pyRiemann-qiskit: A Sandbox for Quantum Classification Experiments with Riemannian Geometry
Authors: Andreev Anton , Cattan Grégoire , Chevallier Sylvain , Barthélemy Quentin
Published: March 2023

Quantum computing is a promising technology for machine learning, in terms of computational costs and outcomes. In this work, we intend to provide a framework that facilitates the use of quantum machine learning in the domain of brain-computer interfaces – where biomedical signals, such as brain waves, are processed.

To this end, we integrated Qiskit, a well-known quantum library, with pyRiemann, a framework for the analysis of biomedical signals using Riemannian Geometry. In this paper, we describe our approach, the main elements of our implementation and our research directions. A key result is the creation of a standardised pipeline (QuantumClassifierWithDefaultRiemannianPipeline) for the binary classification of brain waves. The git repository reported in this paper also contains a complete test suite and examples to guide practitioners. We believe that this software will enable further research on the joint field of brain-computer interfaces and quantum computing.

Plus spécifiquement, l’article se penche sur les récits de démarches thérapeutiques entreprises par diverses catégories d’acteurs en Côte d’Ivoire urbaine dans des espaces thérapeutiques de grande envergure que sont les camps de prière chrétiens et les cliniques de Roqya. L’analyse met l’accent sur les façons dont ces institutions contribuent à redéfinir de nouvelles façons d’envisager la spiritualité et la guérison des afflictions spirituelles.
Le berceau des subjectivités
Authors: Luciani Paul
Published: March 2023

À partir d’une enquête ethnographique en crèche, cet article vise à démontrer l’apport heuristique d’une anthropologie des bébés centrée sur l’étude de l’émergence et de la construction des sujets sociaux. M’appuyant sur l’analyse de trois situations, je propose d’abord une réflexion épistémiologique sur la dimension subjective de l’enquête auprès des bébés ; puis je discute l’hypothèse selon laquelle la relation qu’ils nouent avec les adultes placent ces derniers dans une « situation parentale » ; enfin, je montre que la crèche est un lieu privilégié d’observations du processus de subjectivation des enfants.
Em busca do objeto da Comunicação:
Authors: Matheus Leticia Cantarela , Carlos Barbosa Marialva
Published: March 2023

O ensaio destaca seis contribuições metodológicas de Jesús Martín-Barbero para redefinição ampliada e mais precisa do campo da Comunicação no Brasil a partir dos anos 1990. A influência do autor foi muito além do desdobramento da área na direção de uma vertente culturalista, política e decolonial, tendo ele impactado a própria definição epistemológica da Comunicação, ao promover o deslocamento do estudo dos meios de comunicação para os processos de mediação. Este ensaio apresenta um olhar sobre a definição do objeto da Comunicação a partir de sua herança intelectual; também lembra a cronologia do campo apontada pelo autor, com ajustes ao caso brasileiro; e, finalmente, explica seis principais transformações que a influência de Martín-Barbero permitiu à área. Inúmeras outras contribuições são possíveis de destaque, mas o enfoque deste ensaio se dá em torno do objeto e de algumas premissas na construção do objeto comunicacional.
