Published: March 2023

Objective: To assess prevalence of late ANC initiation and its
associated factors among pregnant women attending in Hawassa Public
Health Facilities, South Ethiopia, 2019. Method and materials:
Cross-sectional study was conducted from June 15 to August 15 /2019
among 392 pregnant women’s who visited Hawassa city’s public health
facilities, Southern Ethiopia for 1 ANC service.
Pregnant mothers were enrolled using systematic technique and data was
collected using semi-structured questionnaires. Epi-data version 3.1
used for data entry and SPSS version 24 for data analysis was used.
Variables at p-value <0.25 on binary model was taken into
multivariable logistic regression and finally significance was declared
at a P-value 0f < 0.05. Results: The prevalence of
late ANC visit was 57.7% (95% CI=52.74-62.57%). Maternal age group,
31-35 years (AOR=4.93, 95% CI=1.70-14.27), Husband with no formal
education (AOR=2.88,95% CI=1.17-7.314), no previous ANC (AOR=2.03, 95%
CI=1.20-3.43), no history of obstetric complications (AOR=4.05, 95%
CI=2.06-7.96), Unplanned pregnancy (AOR=2.40,95%CI=1.23-4.68), and no
partner support (AOR=2.47,95%CI=1.16-5.26) were significantly
associated with increased odds of late ANC initiation. However, Maternal
decision making for service (AOR=0.40, 95%CI=0.18-0.87) were
significantly associated with decreased odds of late ANC initiation.
Conclusion and recommendation: late ANC initiation was high in
the study area. Maternal age, husband level of education, previous ANC
and obstetric complications, type of pregnancy, maternal decision
making, and partner support were significantly associated with late ANC
initiation. The City’s health offices need to provide education about
danger sign of pregnancy and its complication, create awareness about
the importance of early ANC initiation and its recommended time.

RATIONALE: Sample preparation is one of the most crucial steps for MALDI
mass spectrometry imaging (MALDI-MSI). The scientists beginning their
adventure with this technique may be overwhelmed by the variety of
matrices, solvents, concentrations, the ways of their applications, and
the lack of widely available knowledge about the influence of these
parameters on the results. Here we would like to present our experiences
with detailed aspects of matrices deposition, hopefully helpful for the
scientific community. METHODS: In our article, we have tested several
MALDI matrices applied by the SunCollect® system: wet-interface matrix
deposition in the context of lipids analysis. Among them:
2,5-dihydroxybenzoic acid (DHB), norharmane, N-(1-naphthyl)
ethylenediamine dihydrochloride (NEDC), 9-aminoacridine (9AA). We have
optimized the number of matrix layers and nozzle settings in terms of
spectra intensity and the overall quality of obtained ion maps. RESULTS:
Our research presents the influence of the number of matrix layers and
nozzle settings on the results and allows for choosing the optimal
parameters for the analyses. In positive ionization mode, DHB matrix
could be chosen as the first selection. In the negative ionization mode,
DAN matrix produces higher peak intensity in a lower mass range and
seems to provide more information than 9AA. We recommended NEDC for
particular tasks such as glucose analysis. Comparably to remaining
matrices, norharmane significantly changes received ion maps.
CONCLUSIONS: Dealing with such a great amount of data allows us to
notice an interesting conclusion: the obtained ion picture for a
particular ion could differ dramatically with changing the matrix, the
solvent composition, or even the number of matrix layers. This must be
considered when interpreting the result and forces us to compare the
results obtained with different matrices with extreme caution.
Adaptation of Azospirillum to stress conditions: A review
Authors:   Department of Crop Sciences, Faculty of Agriculture, Putra Malaysia University, Al-Tawaha Abdel Razzaq
Published: March 2023

Microorganisms has a vital role in agriculture in order to promote the exchange of plant nutrients and reduce the application of chemical fertilizers. The crucial factor controlling the growth and nitrogen fixation of Azospirillum in the soil is drought, i.e. high temperature and low moisture and salinity. Nevertheless, the crops are highly adapted to drought and saline soils. So, the crop is also to be inoculated with the organism of stress-tolerant nature to establish strong colonization and effective Rhizobiocoenosis.The survival of the inoculated strains at such stress conditions is also very important. Influence of osmotic stress conditions such as salinity and drought on the Azospirillum - plant root association and on the various mechanisms conferring crop response by Azospirillum are unknown. Therefore, a large screening development of stress tolerance in Azospirillum strain with all potential for agricultural crops grown in semiarid regions is highly necessary.

Harmful algal blooms (HABs) consider a global environmental problem. A massive fish death occurred in two coastal Red Sea lagoons: Al-Nawras and Al-Arbaeen (Jeddah, Saudi Arabia), and the main cause was associated to bloom of microalgal Chrysochromulina species which can feed on bacteria (phagotrophic). There are bacterial strains that capable of inhibiting or lysing HAB species by producing algicidal substances. On another hand, the resistant of pathogenic bacteria to drugs have become a critical global threat. Thus, finding an effective alternative solution is essential, especially that taken advantage of the phagocytosis in Chrysochromulina and applied on pathogenic bacteria has not been studied enough yet. The aim of the article is to understanding the relationship that occur between Chrysochromulina and bacteria.

Published: March 2023

La sistematización de experiencias es una práctica que se ha desarrollado con el objetivo de mejorar las actividades realizadas en cualquier ámbito a través de la observación retrospectiva de lo que se ha realizado para identificar los aciertos y las oportunidades de cambio. De esta manera, el profesor puede observar su propio desempeño, así como las interacciones que existen en el aula, y ser crítico con su experiencia para mejorar continuamente su actividad docente.

Por tanto, el objetivo de esta investigación fue proponer una estrategia de sistematización de experiencias educativas en la práctica docente para la asignatura de Tecnologías y Manejo de la Información de la Facultad de Ciencias de la Cultura Física. Para ello, se desarrollaron andamios educativos que se aplicaron en los grupos del primer semestre. En una segunda intervención, se aplicaron encuestas a los estudiantes y se compararon los resultados con grupos en los que no se intervino con andamios, utilizando técnicas estadísticas como Anova, regresión lineal y K-medias.

Al aplicar la estrategia de sistematización de experiencias educativas, se determinó que la planeación con andamios realmente tuvo un impacto positivo en la percepción de los estudiantes. Los resultados muestran que existe una diferencia significativa entre los grupos con y sin intervención, siendo los grupos con intervención los que mejor evaluaron el curso y utilizaron una mayor variedad de medios y formatos de carácter tecnológico.

Se logró que, a través del pensamiento complejo, los alumnos pudieran tener una visión externa de la escuela de las problemáticas que existen en su comunidad. La incorporación de elementos innovadores, como la creación de grupos cerrados con los estudiantes de cada salón en la red social Facebook y las videograbaciones de las clases, fueron elementos que utilizaron en su favor para el aprendizaje de los temas de la materia.

La sistematización permitió adaptar y mejorar la clase al observar las fortalezas y debilidades del profesor en el proceso de enseñanza y las actitudes tomadas por los estudiantes. Esta observación permitió modificar las estrategias utilizadas para la materia y aplicar dichas estrategias en posteriores aplicaciones. En consecuencia, se recomienda la implementación de esta estrategia de sistematización de experiencias educativas en la práctica docente para mejorar el aprendizaje de los estudiantes.

Published: March 2023

Во Введении представлено обоснование актуальности исследования особенностей адаптации у лиц с разным уровнем самооценки в современных условиях мобильности. Представлены результаты теоретического анализа факторов, обуславливающих успешную адаптацию в современной реальности, а также описаны особенности влияния субъективных представлений, самооценки и отношения к себе как детерминант адаптации. Новизна исследования заключается в выявлении и описании содержания субъективных представлений о детерминации успешной адаптации в ситуации повышенной мобильности. В качестве Методов исследования выступили методики: «Факторы успешной адаптации» (Т. Н. Щербакова, Х. Х. Тамасханова), тест «Потребность в достижении» (Ю. М. Орлов, В. И. Шкуркин, Л. П. Орлова), и «Тест самооценки» (С. А. Будасси). Был проведен сопоставительный анализ особенностей самооценки, а также потребностей в достижении у лиц с разным уровнем самооценки. В разделе «Результаты» представлены данные, которые свидетельствуют о специфике субъективных представлений о детерминации успешной адаптации. В большинстве случаев для студентов с успешной адаптацией характерен высокий уровень самооценки (51,3 %), менее выражен средний уровень (37,4 %), еще меньше – пониженный (11,3 %). Указываемые респондентами критерии успешной адаптации больше опираются на категории социального признания и продуктивности, и в меньшей степени – на содержание внутренних переживаний. В Обсуждении результатов представлено описание и интерпретация результатов исследования субъективных представлений о детерминации успешной адаптации в условиях мобильности у лиц с разной самооценкой. Данные эмпирического исследования показывают наличие индивидуальных ресурсов и рисков адаптации личности в ситуации мобильности.

Hyvän työntekijän taidot tietoteknisen toiminnanohjauksen säätelemässä kotihoidossa
Authors: Eskelinen Kaisa
Published: March 2023

Kotihoidon organisaatioissa yleistynyt toiminnanohjaus edustaa hoito- ja hoivatyön johtamiselle ominaista medikaalis-manageristista suuntausta, jossa korostuu työn kustannustehokkuus tietojärjestelmiä hyödyntämällä (Wrede & Henriksson 2004; Henriksson & Wrede 2008). Artikkelissani kysyn, mitkä työntekijän taidot korostuvat ajankäyttöä ja kirjaamista yhdenmukaistavassa toiminnanohjauksessa ja miten toiminnanohjaus sopii yhteen hoivan logiikan (Mol 2008) eli asiakkaan tarpeet kokonaisvaltaisesti ja yksilöllisesti huomioivan työntekijäihanteen kanssa. Aineiston analyysi perustui 24 kunnallisen kotihoidon esihenkilön ja heidän työparinaan toimivan palveluohjaajan haastatteluihin. Analysoin vuosina 2010–2011 toteutetut haastattelut laadullisen deduktiivisen sisällönanalyysin metodein. Käytin aineiston sisällönanalyysissä käsitteitä näkyvyys, kontrolli ja vertailtavuus (Bowker & Star 1999). Ne ovat tietoteknisen luokittelujärjestelmän ja johtamisen periaatteita, jotka ohjaavat työntekijöiden työtä toiminnanohjauksessa. Toiminnanohjaus korostaa hoivatyötä teknisenä, kirjallisena ja ajanhallinnallisena taitona, ei niinkään kokonaisvaltaisena ja ruumiillisena taitona. Onkin tärkeää tukea työntekijän mahdollisuuksia arvioida ja sovittaa itse työtään toiminnanohjaukseen, jotta työntekijöiden hoivan logiikan mukaiset taidot säilyvät toiminnanohjauksen määrittämässä työssä.
The skills of a good worker in elderly home care regulated by enterprise planning system 
Enterprise resource planning (ERP) systems are widespread in home care organizations and represent medico-managerial management of care work, emphasizing cost-effective organization of care work by using information systems (Wrede & Henriksson 2004; Henriksson & Wrede 2008). Based on a content analysis of interviews with middle managers from two municipal homecare organizations in Finland and their service adviser colleagues, this study examines which worker skills are emphasized in ERP that standardizes the use of time and documentation of care work, and how ERP supports the worker ideal according to a logic of care (Mol 2008). This ideal refers to a worker who takes care of customers’ needs holistically and individually. The analysis uses the concepts of visibility, control, and comparability (Bowker & Star 1999), which are the principles of the classification systems of information infrastructures as well as management, and principles which direct workers’ work in the ERP. ERP emphasizes documenting and time management skills, which partly contradicts holistic worker conduct. ERP also emphasizes technical and written skills of care workers, not so much embodied and situational skills. It is, therefore, important to support workers’ discretion and possibilities to adjust their work to ERP, so that they can retain worker skills consistent with the logic of care while engaging in work determined by ERP.

Published: March 2023

Osallisuuden edistämistä pidetään keskeisenä yhteiskuntapoliittisena tavoitteena ja ikääntyneiden osallisuutta vahvistavaa toimintaa järjestetään laajasti eri sektoreilla. Erityisesti erilaisten ryhmämuotoisten toimintamallien on nähty edistävän ikääntyneiden osallisuuden kokemusta. Tämä systemaattinen kirjallisuuskatsaus käsittelee tutkimusjulkaisuja, joissa on tarkasteltu ikääntyneiden ryhmätoiminnan vaikutuksia osallisuuteen ja toiminnan taloudellista arviointia. Osallisuuden kokemuksia oli tarkasteltu monissa tutkimuksissa, mutta taloudellisen arvioinnin näkökulma oli harvinaisempi. Lopulliseen tarkasteluun valikoitui viisi artikkelia. Näissä osallisuutta oli arvioitu monilla erilaisilla mittareilla, mikä vaikeutti vertailtavuutta. Lähes kaikissa tutkimuksissa havaittiin, että interventio paransi osallisuutta jolla-kin mittarilla. Koska tutkimusartikkeleita oli vähän ja taloudelliset arvioinnit oli toteutettu erilaisilla menetelmillä, ei interventioiden kustannusvaikuttavuudesta voida tehdä päätelmiä.
Economic evaluation of group-based intervention for older people and effects on social inclusion
Increasing social inclusion is a central goal of social policy. Activities to increase social inclusion of older people are widely organized in different sectors. Especially, various group-based approaches seem to increase social inclusion of older people. In this systematic review, we examine studies which evaluated the effects of group-based interventions to increase social inclusion of older people, and which also applied an economic evaluation. The perspective of economic evaluation was not common. We could include only five articles in the review. In these articles, social inclusion had been assessed with many different indicators, making studies difficult to compare. Four studies reported that the intervention increased social inclusion regardless of the indicator used. Because the methods in the studies varied, no numerical conclusions could be drawn about the cost-effectiveness of the interventions.

Published: March 2023

Geography planning is an essential element in the creation of a plan. Planners develop a method by analyzing data and identifying goals for the community or the development project. This study aims to analyze how planners or governments analyze geography planning and village funds to improve development programs. This research type is quantitativeâ€”data collection techniques using a closed questionnaire with a Likert scale model and interviews. The population and sample of the study were 47 people. The analysis technique was carried out by processing data collected from respondents, grouping data based on the type of respondent, making tabulations, and carrying out statistical test calculations. The results of this study found that the Village is a geographical manifestation caused by socio-economic, political, and cultural physiographical elements. Geographical planning analysis and village funds are intended for villages with each village planning village development needs. Support for geographic planning analysis and village funds can be seen from the achievement of policy aspects such as agenda setting, policy formulation, policy adoption, policy implementation, and policy evaluation in villages with a low relationship with effectiveness. From development programs. Public services to the point of development programs have an intense relationship, and the accountability dimension is classified as moderate. Productivity dimensions, service quality responsiveness, and responsibility for the development program's effectiveness. The policy on the simultaneous use of village funds and public services on the effectiveness of development programs has a strong relationship of 72.25. However, this study did not examine a low correlation of 0.27.36%.Keywords: Village, Policy, Public, Geography, Planning

Published: March 2023

The local active fault in Bali has a small magnitude (M<5) but has destructive potential because it is very close to residential areas. Mapping the fault area on Bali is needed to identify the parameters of faults. This study used gravity data from GGMplus, topographic data from DEMNAS, and lineaments using ALOS-2 PALSAR-2 data. Validation and interpretation using the geological map of Bali and seismicity data. We interpret the subsurface using the gravity derivative method to identify the type of fault movement. Identify fault locations using lineament extraction from SAR data processed by directional filters. The composite image red-green-blue (RGB) for HH, HV, and VV polarization was used for automatic lineament extraction and then corrected manually. The results of the gravity method succeeded in identifying 29 of the 30 faults from the geological map of the Bali sheet and a new spot from PALSAR-2. Bali land has 12 thrust faults, 11 strike-slip faults and six normal faults. The image of PALSAR-2 (L band) has succeeded in making a fault lineament map for the Bali region. The lineament extraction results from PALSAR-2 obtained four new faults (Pesanggaran, Sepang, Tegal Badeng, and Banyuwedang), while four faults were not identified (Tampaksiring Fault, Plaga, Mambal, and Munduk-Rajasa). NE-SW dominates the strike directions, and the dip angles are 45-80 degrees. We propose 30 faults in Bali, including 26 defects from geological maps with changes in length and location shift and four new marks extracted from automatic lineament.Keywords: Remote Sensing, Earthquake, Derivative Gravity, Lineament, SARÂ

Published: March 2023

In political preferences, religion plays a vital role as a consideration for the millennial generation. This is because Indonesia still considers religion in setting policies as it does in political parties and general elections. This study analyzes the political communication system of millennial Muslim Islam on social media in the face of the 2024 presidential election (netnographic analysis). This study applies the netnographic research method through a qualitative approach to understand how the Islamic political communication system works in millennial Muslim society on social media and the geopolitics of millennial Muslims in Indonesia in the face of the 2024 presidential election. Data collection uses analytics related to election dataâ€”President in 2024. The study results show that the application of political communication among millennial Muslims on social media is in the form of support and criticism on the hashtag #pemilu2024. Social media proves that distance and time limits are not obstacles to voicing opinions, criticizing and supporting each other. Several things that can be done to map Islamic political communication systems and millennial Muslim geopolitics on social media include: (1) Analyze Islamic political trends that occur on social media, such as Twitter, Facebook, and Instagram, by searching for keywords related to Islamic politics and monitor how communication patterns are between Muslim millennials; (2) Understanding millennial Muslim sentiments on social media by reading and monitoring conversations on social media; and (3) understand the patterns used in communicating, taking into account the type of content they share, the frequency of social media use, as well as the most used platforms. Too much social media reach without knowing boundaries makes social media challenging to control. The strength of political competition becoming increasingly evident must be accompanied by carefulness in filtering information not to complicate the situation. As millennials amid vulnerable hostilities, they should be able to become pioneers or fortresses in avoiding the opposing currents of the impact of social media in political times.Keywords: Political Communication, Millennial Muslims, Geopolitical Mapping, Social Media, Presidential Election

Published: March 2023

The online learning process can be done through various e-learning platforms. The determination of the platform should consider the dimensions of the teacher and those of the students. This study aims to analyze the use of the e-learning platform from the perspective of teachers and students in junior high school. This quantitative research design uses a descriptive method. Participants consisted of 91 teachers and 165 students in Medan City. Data were collected by questionnaire via Google Forms. Quantitative data analysis used descriptive statistics to obtain the percentages for each indicator. Then the presentation of data is done with tables and diagrams. The results showed that teachers and students have different perspectives on each e-learning platform supporting the learning process. Based on the philosophy of teachers and students, it can be stated that 1) teachers and students prefer Google Classroom to Edmodo as an LMS in Online Learning. This is because Google Classroom is easier to use, more interactive, and more efficient; 2) Google Meet is the application most often used and preferred by teachers and students in direct virtual Learning. Even though Zoom Cloud Meeting has a more attractive appearance and features, Google Meet is easier to access and considered to save internet quota; 3) As many as 43% of teachers and 49% of students prefer a combination of Google Classroom, Google Meet, WA Group to support the online learning process. Meanwhile, 41% of teachers and 42% of students prefer a combination of Google Classroom, Zoom Cloud Meeting, and WA Group as an e-learning platform. Only a few teachers and students choose the variety of Edmodo Zoom and WhatsApp groups and the combination of Edmodo, Google Meet, and WhatsApp groups.Keywords: E-Learning Platform, Student Perspective, Teacher Perspective
How can challenges in left behind places be addressed? Learning from Greater Lille, Nantes, the Ruhr region, San Antonio and Estonia.
Authors: Taylor Abigail
Published: March 2023

Addressing issues of regional inequalities and supporting ‘left behind’ regions is a global issue, but analysis of international regions that have successfully levelled up is limited. Developing and implementing effective place-based policies is critical for recovery from the Covid-19 pandemic but remains an under-explored issue. This paper provides insight into different policies and tools used to support left-behind places. Comparing experiences of addressing socio-economic challenges in Greater Lille, Nantes, the Ruhr region, San Antonio and Estonia, it discusses what ingredients for successfully addressing inequalities are, what has worked well, and future challenges. It identifies seven “foundations” for levelling up and stresses the importance of levelling up “within” regions and not just levelling up “of” regions given how despite economic growth in the case study places, clear socio-economic disparities continue to exist. In particular, it debates opportunities to support levelling up through financial management and governance tools.
Plasma Welding of Aluminum in an Oxygen-Free Argon Atmosphere
Authors: Klett Jan , Bongartz Benedict , Wolf Thomas , Hao Chentong , Maier Hans Jürgen , Hassel Thomas
Published: March 2023

Plasma welding is characterized by a high concentration of energy, which allows for high welding speed and leads to less distortion and residual stresses compared to conventional welding processes. Due to the local and controlled heat input, the process is suitable for sheet metal from ≈ 0.1 mm (micro plasma) up to ≈ 10 mm. In the case of aluminum and its alloys, the natural aluminum oxide layer on the metal surface limits the productivity of the plasma welding process. The electrically isolating and thermally insulating Al2O3layer has a significantly higher melting point compared to the aluminum (Tm(Al2O3)= 2072 °C vs.Tm(Al)= 660 °C). The oxide layer hinders the formation of a stable arc and can even impede the joining formation. In order to remove the oxide layer and to produce quality welds with a DC process, it is necessary to weld with reverse polarity to use the principle of cathodic surface cleaning. However, this leads to increased electrode wear and increased penetration depth, which is not always desirable.

In the study presented, the use of silane to reduce the oxygen content in the welding atmosphere as well as to remove the natural aluminum oxide layer on the metal surface was investigated. As previous studies have shown that the use of silane-doped plasma-gases is suitable for removing the superficial oxide layer on aluminum components, high-quality welded joints were expected. Quality welds with sufficient dilution were achieved using a transferred arc silane-doped helium plasma. In contrast, welding with an argon-silane mixture led to excessive pores formation. Additionally challenges to stabilize the arc process were identified and ramifications with respect to process optimization are discussed.

In this paper study for wave propagation in non-homogeneous porous plate sample with slowly varying refractive index is presented. It is based on simple symmetric solution of the wave equation for linearly polarized electromagnetic wave aligned into the porous plate perpendicularly to the external surface. Using correct boundary conditions both the transverse electric (T.E) and transverse magnetic (T.M) modes, named shortly by (T.E.M) mode for electromagnetic wave, are considered. The Wentzel-Kramers-Brillouin (W.K.B.) solutions for symmetric incident irradiation of fixed power generated at the plate surfaces was obtained. It is done the analysis of the reflection and transmission coefficients on the surfaces of plate.

Published: March 2023

One of the fundamental issues of modern society is access to interesting and useful content. As the amount of available content increases, this task becomes more and more challenging. Our needs are not always formulated in words; sometimes we have to use complex data types like images. In this paper, we consider the three approaches to creating recommender systems based on image data. The proposed systems are evaluated on a real-world dataset. Two case studies are presented. The first one presents the case of an item with many similar objects in a database, and the second one with only a few similar items.
A Novel Method for Fast Generation of 3D Objects from Multiple Depth Sensors

Published: March 2023

Scanning real 3D objects face many technical challenges. Stationary solutions allow for accurate scanning. However, they usually require special and expensive equipment. Competitive mobile solutions (handheld scanners, LiDARs on vehicles, etc.) do not allow for an accurate and fast mapping of the surface of the scanned object. The article proposes an end-to-end automated solution that enables the use of widely available mobile and stationary scanners. The related system generates a full 3D model of the object based on multiple depth sensors. For this purpose, the scanned object is marked with markers. Markers type and positions are automatically detected and mapped to a template mesh. The reference template is automatically selected for the scanned object, which is then transformed according to the data from the scanners with non-rigid transformation. The solution allows for the fast scanning of complex and varied size objects, constituting a set of training data for segmentation and classification systems of 3D scenes. The main advantage of the proposed solution is its efficiency, which enables real-time scanning and the ability to generate a mesh with a regular structure. It is critical for training data for machine learning algorithms. The source code is available at https://github.com/SATOffice/improved_scanner3D.
Emerging Modularity During the Evolution of Neural Networks
Authors: Praczyk Tomasz
Published: March 2023

Modularity is a feature of most small, medium and large–scale living organisms that has evolved over many years of evolution. A lot of artificial systems are also modular, however, in this case, the modularity is the most frequently a consequence of a handmade design process. Modular systems that emerge automatically, as a result of a learning process, are very rare. What is more, we do not know mechanisms which result in modularity. The main goal of the paper is to continue the work of other researchers on the origins of modularity, which is a form of optimal organization of matter, and the mechanisms that led to the spontaneous formation of modular living forms in the process of evolution in response to limited resources and environmental variability. The paper focuses on artificial neural networks and proposes a number of mechanisms operating at the genetic level, both those borrowed from the natural world and those designed by hand, the use of which may lead to network modularity and hopefully to an increase in their effectiveness. In addition, the influence of external factors on the shape of the networks, such as the variability of tasks and the conditions in which these tasks are performed, is also analyzed. The analysis is performed using the Hill Climb Assembler Encoding constructive neuro-evolutionary algorithm. The algorithm was extended with various module-oriented mechanisms and tested under various conditions. The aim of the tests was to investigate how individual mechanisms involved in the evolutionary process and factors external to this process affect modularity and efficiency of neural networks.
Academic Engagement in Sport for Development: Niche or Growing Community?
Authors: Moustakas Louis , Petry Karen , Bauer Katrin
Published: March 2023

Over the last two decades, the sport for development (SFD) sector has grown significantly, and there has been a concurrent increase in research and educational activities to support the field. In particular, academic institutions are taking a more significant role, contributing to a growing body of literature and developing numerous SFD-specific courses. Despite these initiatives and the important role assigned to academia, academic activities related to SFD have remained fragmented along geographic or disciplinary lines, and our knowledge of academic activities and collaborations is limited and focused on actors in the Global North. This study seeks to address these gaps and, through an international survey of academic institutions, aims to (1) establish the teaching, research and partnership activities within and between academic institutions around the globe; and (2) identify challenges and inform solutions for greater cooperation within and between academic institutions in the SFD context. Overall, our results show that the SFD is a highly multidisciplinary field involving institutions from a perhaps wider-than-expected range of countries. However, funding, support and recognition of SFD and associated academic actors, especially in the Global South, remains limited. To conclude, we propose potential ways forward to address some of these issues.
Teacher Emotional Support and School Engagement: The case of Physical Education Teachers and Students in a Prominent Local College
Authors: Lobo Joseph
Published: March 2023

A large number of published papers have investigated the relationship between perceived teacher emotional support and students’ engagement in school across a variety of subject areas at the primary and secondary levels. However, very few or none of these studies examine the topic in the context of physical education in higher education. It would be highly desirable for a study comparable to this one to be carried out within the context of tertiary education in order to address the dearth of scholarly works that concentrate on these two constructs. In light of this, the current study investigated the connection between teachers’ emotional support and their student’s level of engagement in their academic work. The participants in the study were undergraduate students (males = 374, females = 536) who were enrolled in minor PE courses at a prominent local college in Angeles City, Philippines. Following the calculation of Spearman’s rho and multiple regression analyses, the findings revealed that perceived teacher emotional support (along with its three distinct features: positive atmosphere, teacher sensitivity, and regard for the adolescent perspective) is significantly associated with [r(908) =.519, p < .05)] and has a direct influence on [F(3, 906) = 120.508, p <.001] school engagement. Additionally, this study highlighted the critical role that PE instructors play in providing students with emotional support, which in turn leads to higher levels of engagement and achievement reports. The presentation includes suggestions for the professional development of teachers of PE and future research initiatives.
Sustainability in Sport-Related Studies: A Non-Systematic Review to Increase the Sports Contribution to the 2030 Agenda
Authors: Annesi Nora , Battaglia Massimo , Frey Marco
Published: March 2023

This paper aims to identify all of the unexploited potentialities of sports activities with regard to sustainability by answering the following question: Considering the priorities that the 2030 Agenda identified with regard to sustainability, what does sport contribute to the process of transition towards a more sustainable global scenario? According to the European Union Council, sport and physical activity play a strategic role in the global challenge toward sustainability and achieving the 17 SDGs. The contribution of sport to the 2030 Agenda is indeed strategic. However, through a non-systematic review, the authors have observed almost a complete absence of SDGs within sports literature. Discussing the results through the lens of the SDGs, the authors have identified a series of qualitative and quantitative research opportunities connected with the 17 SDGs and related targets. The authors have also identified a total of 27 research hypotheses. This evidence could support academics, sports managers, professionals, and practitioners in identifying their contribution to the global priorities towards sustainability.

Authors: Nyanga Takupiwa
Published: March 2023

Social media has positioned itself as one of the most effective and efficient engines of disseminating both social and business information throughout the world. The purpose of this study was to establish the role of social media in enhancing business activities of SMEs in Gwanda town. The study used a qualitative research methodology where 23 participants who were drawn from 7 organizations were interviewed using face to face interviews. A combination of purposive and convenience sampling techniques was used to select the 7 organizations and 23 participants who participated in the study. Thematic data analysis was utilized to analyze the data that was solicited using a 14 item interview guide. The study established that to a larger extent social media is a business enabler. Social media improves the effectiveness and efficiency of organizations by promoting an easy flow of information within departments and with external stakeholders. Social media increases the profitability and the general performance of SMEs and directly and indirectly reduces operational costs. Social media helps managers to keep workers updated about the developments taking place in the organization. It was also found that to a lesser extent social media hinders the performance and growth of organizations since it can easily be abused by employees who spend most of the business time chatting and conversing with friends and relatives on issues that are not related to work.
