Published: May 2023

Introduction: Women’s football require optimal neuromuscular system development for injury prevention and performance optimization. Standardized neuromuscular training programs have shown promising results in reducing injuries and functional asymmetries, but evidence on their impact on performance is limited.

Methods: This research examined the effects of a 10-week neuromuscular training program on physical performance and asymmetries in female football players. Thirty-eight female players from two Spanish Second Division women’s football teams participated in the study. The physical performance tests used were: ankle dorsiflexion, bilateral and unilateral horizontal jump, bilateral and unilateral vertical countermovement jump, 40 m sprint including partial times at 10, 20 and 30 m and the 505 test for change of direction evaluation. For 10 weeks, players in the experimental group performed three weekly 24-min neuromuscular training sessions. Participants in the control group completed their normal 24-min strength and conditioning program.

Results: The main results were that maximal linear velocity and change of direction skills showed the most notable improvements [effect size (ES), 0.46 to 0.59] after implementation of the training program, ankle dorsiflexion and jumping skills, also improved although, to a lesser extent (ES, <0.35) while asymmetries between limbs were reduced. Maximal running speed improved in the intervention group (p < 0.001) with a mean ES −0.59.

Discussion: We conclude that a 10-week neuromuscular training program can be a sufficient stimulus to improve football-specific performance variables in high-level female football players. Therefore, female players and coaches should be aware that weekly inclusion of strength, power and dynamic balance exercises following a neuromuscular paradigm is helpful for football-specific performance improvement.

Published: May 2023

Background

Work addiction (WA), which can impair personal relationships, engagement in recreational activities, and/or health, is a behavioral addiction. A tool for the early detection of WA in China is needed.

Objective

The aim of this study was to develop and determine the validity and reliability of a Chinese version of the Bergen Work Addiction Scale (C-BWAS).

Methods

Two hundred social workers who provided post-discharge services for adolescents with non-suicidal self-injury (NSSI) were enrolled in this study. The construct validity of the C-BWAS was assessed by confirmatory factor analysis (CFA). Criterion validity was assessed by conducting Pearson correlation analyses of C-CWAS scores with Hamilton Depression Scale (HAM-D) and Hamilton Anxiety Scale (HAM-A) scores. Cronbach’s α and the intra-class correlation coefficient (ICC) were used to evaluate the reliability of the C-BWAS.

Results

CFA confirmed a one-dimensional structure of the C-BWAS with good construct validity indices [comparative fit index (CFI) = 0.964, Tucker–Lewis index (TLI) = 0.951, root-mean-square error of approximation (RMSEA) = 0.079, and minimum discrepancy Ĉ/degrees of freedom (Cmin/DF) = 0.362]. The standardized regression weights ranged from 0.523 to 0.753. All C-BWAS items loaded on one major factor (loading weights, 0.646–0.943). Coefficients of correlation between C-BWAS scores and HAM-D and HAM-A scores were 0.889 and 0.933, respectively. The Cronbach’s α coefficient and ICC for the instrument was 0.837 and 0.905, respectively.

Conclusion

The presently developed C-BWAS showed very good reliability and acceptably validity. It can be employed as a useful tool for assessing WA severity in social workers who provide post-discharge services for adolescents with NSSI.
Leaders’ mental health in times of crisis: work intensification, emotional demands and the moderating role of organizational support and self-efficacy
Authors: Wittmers Anja , Maier Günter W.
Published: May 2023

This article focuses on leaders’ specific demands in times of crisis and the role of personal and organizational resources regarding mental health. The COVID-19 pandemic has led to increased levels of responsibilities, particularly among leaders. To deepen the understanding about the resulting consequences in terms of leaders’ demands and resources, we conducted a mixed methods study with a sample of 60 leaders from lower and middle management. We hypothesized leaders’ work intensification and emotional demands to be related with higher irritation and exhaustion. Consistent with the Job Demands-Resources model and the Conservation of Resources theory, we examined organizational instrumental support and occupational self-efficacy as possible moderators and assumed a buffering effect on mental illness. Our quantitative results indicated organizational instrumental support as a moderator for the relation of work intensification and mental illness. In terms of self-efficacy and work intensification, the results contradicted our expectations. For emotional demands, only the main effects could be found. In the qualitative part of our study, we found evidence for the importance of work intensification, emotional demands and organizational instrumental support in the leaders’ everyday experience and gained a deeper understanding of the constructs’ nature by means of examples. The integration of our quantitative and qualitative results has important and concrete implications for organizations how to support leaders in times of crisis and accelerated changes at work. This further underlines the necessity to consider leaders as an important target group of occupational health measures.

Background

Most studies have focused on overweight/obesity and its secular trend, with insufficient studies on the factors influencing thinness and trends recently. To examine the trends of prevalence and sociodemographic determinants of thinness, overweight, and obesity among Chinese children and adolescents aged 7 to 18 years from 2010 to 2018.

Methods

This study was based on cross-sectional data of 11,234 children and adolescents aged 7 to 18 years from the Chinese Family Panel Studies (CFPS) in 2010, 2014, and 2018, including anthropometric and sociodemographic characteristics variables. The nutritional status of each individual was determined according to China and WHO criteria. The demographic characteristics of different subgroups were tested by chi-square, and log-binomial regression was used to analyze the trend of prevalence and the relationship between sociodemographic characteristics and different nutritional statuses.

Results

After adjusting for age, from 2010 to 2018, the overall prevalence of thinness decreased, and the prevalence of overweight increased in Chinese children and adolescents. The overall prevalence of obesity declined in boys and increased in girls, but in adolescents aged 16–18 years, it increased significantly. Log-binomial regression analysis showed that among all subjects, time (years), 16–18 years were negatively associated with thinness, while 13–15 years, walking to school, large family size, and paternal age at childbirth older than 30 years old were positively associated with thinness; 10–12/13–15/16–18 years, boarding at school, medium and large family sizes, and mother's education at junior middle school/junior high school and above were negatively associated with overweight/obesity, while time (years), boys were positively associated with overweight/obesity in the multivariate model by adjusting for the statistically significant factors (all p < 0.05).

Conclusion

Chinese children and adolescents are facing a double burden of malnutrition. Future public health policies and interventions should prioritize high-risk groups specifically young age groups, boys, larger family sizes and so on.

Published: May 2023

Microplastic (MP) particles are considered noxious pollutants due to their presence in aquatic habitats at almost every level of the food chain. Thus, the entry of MP particles into marine waterbodies has triggered a common research interest. Until recently, the toxicity of polystyrene towards aquatic creatures in comparison to other polymers has not been widely investigated. This article provides an extensive overview of the occurrence of microplastic particles, the route of polystyrene (PS) in the aquatic ecosystem, the PS properties characterization, and its noxious effects on the aquatic biota, particularly fishes and microalgae. Alarming high levels of polystyrene were found in urban, coastal, and rural surface waters and sediments. The fast-screening technique began with a stereoscope to determine the polystyrene particles’ shape, size, and color on the organism. SEM and complemented by micro FTIR or Raman spectroscopy were used to evaluate MP’s polymer structures. The findings present evidence suggesting that polystyrene buildup in fish can have long-term and unknown consequences. Meanwhile, the presence of polystyrene on microalgae causes a decrease in chlorophyll concentration and photosynthetic activity, which may disrupt photosynthesis by interfering with the electron characters and leading to the production of reactive oxygen species (ROS).

Published: May 2023

In this study, oleogels were prepared by the emulsion-template method using egg-white protein microgel as a gelator and xanthan gum (XG) as thickener. The physicochemical properties of the emulsion and oleogels were investigated. The adsorption of protein on the surface of the oil droplet reached saturation when the protein microgel concentration reached 2%. The excess protein combined with XG and accumulated on the outer layer of the oleogel, which prevented the emulsion from flocculation, enhanced the oil-holding capacity of the oleogel, and had a positive effect on preventing the oxidation of oil. When the concentration of XG was less than 0.4%, the EWP microgel, combined with the XG, stabilized the emulsion. As the concentration of XG was greater than 0.4%, excessive XG in the emulsion improved the viscosity and mechanical properties of the emulsion to prevent the aggregation of oil droplets. However, the change in XG concentration had no significant effect on the oxidation of the oil.

Feminisme dan Keadilan Reproduktif: Mempersoalkan Aborsi Berdasarkan Pengalaman Aktivisme HKSR
Authors: Boangmanalu Abby , Pratiwi Wulandari Asri
Published: May 2023

In Indonesia, abortion is categorized as an illegal and criminal act. Even though abortion due to medical indications and rape are exempt from criminal status, access to legal abortion is still almost impossible. Therefore, discussion about legal abortion and safe abortion cannot be done separately, for the criminalization of abortion is one of the factors behind unsafe abortions. Through focused discussions with 20 women activists representing civil society organizations who advocate for gender justice and SRHR in Indonesia, this research aims to document and reflect critically on the situation of reproductive injustice in the issue of abortion in Indonesia using a feminist lens. Building this research within the framework of reproductive justice thinking based on feminist praxis, we selected women activists as our informants. SRHR activists are the closest to and the most involved subjects in the feminist praxis of promoting reproductive justice, particularly on the issue of abortion
Tendinţe actuale în evoluţia vieţii de familie la Dunărea de Jos
Authors: CELMARE Valerica
Published: May 2023

The region Dunărea de Jos is an area with an own cultural, identitary and historical specificity, which has synthesized in the collective mind the imprint of all the times that had alternated on these territories. The variation of the socio-economic and political context also influenced the family life of the inhabitants. The ethnic and religious diversity has, in the past, raised the issue of mixed marriages and of differences in family models of communities which were cohabiting. During the period of communism, the family is marked by the rapid process of industrialization of urban areas, by the migration of people from village to city and the birth policies implemented by the government. After the Revolution of December 1989, a period of socio-economic and political transition was instituted in which the family had subjected to a process of diversification in her typological and structural, value and relational aspects. If in the past, the traditional family model was dominant, in today's society we encounter more and more family models, such as single-parent family or consensual union. The migration of residents to western European countries again brings up the issue of interethnic and interreligious mixed marriages or transnational marriages. However, the separation of the couple and the separation of children from their parents is by far one of the most dramatic problems of family life encountered in the researched area. The way parents relate to their children and to the system of values they adopt it in educating children brings into question a mentality inherited from the period of communism, in which many parents, on the basis of poor incomes, gave their children "to the state", meaning they had entrusted their children to the authorities for the purpose of their care and education. Currently, the authorities working towards promoting the protection of children's rights are fighting an assiduous battle to correct this mentality, as the number of children separated from their parents is very high. Based on the above arguments, I set out to make an X-ray of family life in the region Dunărea de Jos, with the following objectives: identifying family models in the studied region, describing the general characteristics of the family in the region Dunărea de Jos, exploring the attitude of local people towards family life, exploring the principles and values regarding the upbringing and education of children.
Key Issues of English for Special Purposes (ESP) Competence in Adult Education and Career Development

The main aim of the foreign language learning is to form the foreign language communicative competence. The reality is such that we could not even imagine what jobs will appear on the labour market in the nearest future in the conditions of increasingly developing information society. There is a kind of a gap between the demand and offer of language skills and this gap should be bridged if want to integrate as equal members of the European community. Currently we can distinguish three paradigms of professional education: cognitive-oriented, activity-oriented and personality-oriented. But currently there is also competence-oriented paradigm, where the main priority is not a mere knowledge accumulation, but the formation of various skills, wish and ability to study life-long. Nowadays there is a variety of innovative language education types which appeared in response to social and economic needs: online education, distance learning, electronic learning, cross-cultural learning, multi-lingual learning, resource-based learning, virtual education, problem-based learning, technology-based learning, project-based learning, flexible learning, active learning, case-based learning, discovery learning, digital learning, blended learning, web-based learning, computer-aided learning, situation-modelling learning, debatable issues learning, content-based instructions method and many others. The main distinguishing feature of the foreign language teaching for special purposes is its communicative bias, based on the following methodological principles: authenticity, informative richness, novelty, functionality, actuality. The processes of globalization and internationalization influence the system of higher education demanding changes in syllabuses and curricula structures and contents, especially of foreign language for special purposes.

El presente artículo pretende revisar parte del proceso de construcción del campo de las políticas culturales llevado a cabo por la UNESCO en las décadas de 1970 y 1980. Serán consideradas tanto la Declaración de la Conferencia Intergubernamental sobre Políticas Culturales en América Latina y el Caribe 1978, como las resoluciones aprobadas en la Conferencia Mundial de Políticas Culturales MONDIACULT 1982. Los análisis buscan dialogar con la temporalidad en que las materias fueron propuestas, reflexionando sobre algunos de los problemas estructurales brasileños que no permitieron la consolidación efectiva de políticas públicas en el campo de la cultura que aspiren al desarrollo social y humano, teniendo la cultura como afirmación de vida y libertad. Comprobamos que aún quedan temas y cuestiones residuales, pendientes de resolución y que necesitan ser reubicados en la pauta de las discusiones de políticas públicas, pero ahora en un contexto muy diverso y aún más complejo.
Utilizing Deep Reinforcement Learning and QLearning algorithms for Improved Ethereum Cybersecurity
Authors: Kabanda Gabriel , Chipfumbu Dr. Colletor Tendeukai , Chingoriw Tinashe
Published: May 2023

The purpose of the research is to explore and develop Deep Reinforcement Learning and Q-Learning algorithms in order to improve Ethereum cybersecurity in contract vulnerabilities, the smart contract market and research leadership in the area. Deep Reinforcement Learning (Deep RL) is gaining popularity among AI researchers due to its ability to handle complex, dynamic, and particularly high-dimensional cyber protection problems. The benchmark of RL is goal-oriented behavior that increases rewards and decreases penalties or losses, and enhances real-time interaction between an agent and its surroundings. The research paper examines the three major cryptocurrencies (Bitcoin, Litecoin and Ethereum) and the role played by cyber-attacks.The Design Science Research Paradigm as applied in Information Systems research was used in this research, as it is hinged on the idea that information and understanding of a design problem and its solution are attained in the crafting of an artefact. The proposed constructs were in the form of Deep Reinforcement Learning and Q-Learning algorithms designed to improve Ethereum cybersecurity. Smart contracts on the Ethereum blockchain can automatically enforce contracts made between two unknown parties. Blockchain (BC) and artificial intelligence (AI) are used together to strengthen one another's skills and complement one another. Consensus algorithms (CAs) of BC and deep reinforcement learning (DRL) in ETS were thoroughly reviewed. In order to integrate many DCRs and provide grid services, this article suggests an effective incentive-based autonomous DCR control and management framework. This framework simultaneously adjusts the grid's active power with accuracy, optimizes DCR allocations, and increases profits for all prosumers and system operators. The best incentives in a continuous action space to persuade prosumers to reduce their energy consumption were found using a model-free deep deterministic policy gradient-based strategy. Extensive experimental experiments were carried out utilizing real-world data to show the framework's efficacy.
Embracing a Material Turn in Software Embedded Design
Authors:   University of Waterloo, Przybylski Maya , Parkin J. Cameron ,   University of Waterloo
Published: May 2023

Architects are increasingly bundling digital components to¬gether with physical assemblies in their pursuit of responsive (or sentient, adaptive, interactive) architecture where hard¬ware and software work together with physical assemblies to mediate the physical environment in real time. Given that 1) architects are responsible for creating built environments capable of enhancing certain values while downplaying or rejecting others and 2) digital components, such as software and data, have direct spatial, social and cultural agency; this practice, labelled here as software-embedded design (SED), calls for a new set of methods for understanding and support¬ing architects’ engagement with their projects’ computational elements, their soft materials. This paper advances efforts to build this critical computational literacy for SED designers by introducing and testing an analytical framework which offers a new lens through which to consider the digital components used in SED projects. As soft materials become part of an ar¬chitect’s toolkit, it is imperative that the values and objectives embedded in computational components of a project and the critical practice around their use match those projected and exhibited towards its physical elements. The paper is organized in two parts to expand the lenses through which designers engage SED by foregrounding the complex interplay between materials, computational elements and real-world outcomes. The first part of the paper elaborates on how a materialist account of digital technology establishes new obligations by recognizing that managing computational elements’ roles in shaping projects’ (material, spatial, social and ethical) outcomes falls into the domain of the designer. The second part proposes the Project Anatomy analytical framework designed to simultaneously examine a project’s soft and hard materials in order to better grasp the relationship between computational components, physical materials and real-world outcomes. A reflection on the tool foregrounds the unique position of SED designers, through their evolving expertise in both soft and hard materials, to find new purchase on materially-oriented, socially-minded engagements with the computational components increasingly proliferating in our built environment.
Enhancing the financial position of cities: Evidence from Dakar
Authors: Delbridge Victoria , Haas Astrid , Harman Oliver , Venables Anthony , Dia-Sarr Khady
Published: May 2023

The city of Dakar is one of the only cities in Africa to come close to taking a municipal bond to market. The US$40 million bond, set to launch in 2014, was designed to fund a new market hall for informal traders in the city. The market would relocate more than 4,000 street vendors, with the aim of moving them from side streets into a safe and central place to sell their goods, with access to credit agencies and other market services. Development partners, including the Bill and Melinda Gates Foundation, the World Bank’s Public-Private Infrastructure Advisory Facility (PPIAF), Cities Alliance, and USAID, played a crucial role in making the bond terms viable – both in shouldering the financial burden of developing internal creditworthiness, and in providing expertise and guarantees to reduce the risk. Although the bond’s launch was ultimately stopped by national government decree, the process of preparing for the bond has greatly improved the financial management capabilities and creditworthiness of the city. As a result, Dakar’s bond journey is still paying dividends to the city today, with a number of successful concessional and commercial loans. The process also deepened the city’s connection with its residents – with small bond denominations, informal traders were one of the key investors. The motivation for the bond was in part due to the city’s lack of control over its financial resources. While the most recent decentralisation law amendment, Acte III de la Décentralisation of 2013, has seen many responsibilities devolved to the local level, finances to deliver on this new mandate have not followed. In fact, all revenue and expenditure for local governments in Senegal are processed at the national level, leaving little room or incentive for financial reform. Surprisingly, despite this, the law gives local governments relative independence in taking on debt. This meant that when Mayor Sall came into office with a vision for change, the only viable financing opportunity within the city of Dakar’s control was via the latter. This legislated independence is also the reason why the halting of the bond was so heavily contested. The city of Dakar provides an example of the importance of the political landscape in effecting any innovative reforms, as well as the need for the national government to buy-in to the fact that successful cities are in their interest as well. This is particularly critical in Dakar’s case, given the city’s finances are managed at the national level. Fortuitously, the national government is now beginning to focus on improving local revenues, primarily through property taxes, as well as better coordination amongst different stakeholders through a dedicated department and the ‘Local Fiscality Commissions’ described below.

Additionally, prior reviews have inadequately examined the methodological rigor and the distributional characteristics of articles within such an area. This systematic review provides information about the geographic spread and breadth of digital games use in entrepreneurship education literature. More importantly, the current analysis provides in depth assessment of the methodological attributes of published articles in the discipline. Based on the comprehensive evaluation, future research directions are suggested to strengthen this area of study.
Magnetic and electric properties of spinel oxide CoV2O4 (001) films
Authors: Hidaka Atsushi , Koizumi Hiroki , Yanagihara Hideto
Published: May 2023

The epitaxial film growth of CoV2O4 (CVO) on a MgO (001) substrate was successfully achieved using a reactive co-sputtering technique. To explore the conductive CVO films at RT, we grew the films under various conditions, including oxygen-gas flow rates and input radio-frequency power for each target. The Néel temperature of the film was approximately 160 K, which is consistent with previously reported values for bulk CVO. The film was found to be conductive over a wide temperature range and exhibited a negative resistivity temperature coefficient. The mechanism governing the temperature-dependent resistivity of the film can be explained using the one-dimensional variable range-hopping model, at least for temperatures higher than the Néel temperature. The CVO films exhibited a lattice constant close to that of spinel ferrites; therefore, they can be used as conductive buffer layers for electrodes in spintronic applications.

Constative experimental study of values dynamics of the competence of personal, social development and learning to learn of primary school students
Authors: Biculescu Florina-Teodora
Published: May 2023

The article contains experimental research at the acknowledgement stage aimed at evaluating the values of the competence of personal, social development and learning to learn in terms of axiological reference of students, by which we consider a system of desirable values, suitable to be formed in primary education. The pedagogical experiment was organized in grades 1-4, during 2018-2022 on a sample of 68 students from primary education. The experimental approach allowed the detection of the following problems that become impediments in the process of forming the values of the competence of personal, social development and learning to learn: difficulties in expressing empathy, respect for classmates and friendship, inconsistencies in affirmation by assuming responsibility, assertive communication, innovative spirit and autonomy in the school group, which demonstrates the need to design axiological education, at the level of functional strategies for the formation of the axiological referential that represents the competence of personal, social development and learning to learn of primary education students.

A Novel One-bit Dynamic Quantizer for Event-Triggered Control Systems
Authors: Almakhles Dhafer , Abdelrahim Mahmoud
Published: May 2023

We investigate the design of quantized event-triggered controllers for LTI systems with unknown initial states. The proposed approach is novel and incorporates interesting features. First, the quantizer that we synthesize is dynamic with exponential behaviour, which enables us to capture the state in a finite time. Second, once the state is captured, the quantization error is guaranteed to remain bounded thanks to the sliding mode feature. Third, the quantizer dynamics only depend on the sign of the quantization error, which allows for one-bit transmission rather than packet-based transmission. Moreover, the event-triggering mechanism that we consider is also dynamic and depends only on locally available information. The overall system is modeled as a hybrid dynamical system and the closedloop stability is investigated using Lyapunov functions. The approach ensures global asymptotic stability property for the closed-loop system. Moreover, Zeno behavior is prevented by means of time regularization techniques. The effectiveness of the proposed approach is illustrated by numerical simulation.
Median Filters for Switching Noise Mitigation in Oversampled Power Electronics Control Systems
Authors: Cvetanovic Ruzica , Petric Ivan , Mattavelli Paolo , Buso Simone
Published: May 2023

This article addresses switching noise propagation and its suppression in multi-rate control systems, where the inductor current is oversampled, digitally filtered and the control execution is decimated to single(double)-sampled pulse-width modulation (PWM). The operating points where the sampling instants occur near the switching ones are critical for switching noise sensitivity. It is shown that, when the number of the corrupted samples is high with respect to the number of samples used for filtering, typically considered moving average filters (MAFs) bring a detrimental impact. As an alternative, median filter (MED) is proposed. To decouple the ranking within MED from the switching ripple, repetitive ripple removal is added beforehand. Multi-rate PWM control with the proposed feedback filtering outperforms state-of-the-art double-sampled PWM by eliminating the well-known switching noise sensitivity for small and large duty cycles. In addition, noise-sensitive operating point regions that appear with MAF are successfully suppressed.
