Published: March 2024

This research paper explores the foster care framework in Greece, with a particular focus on the triadic relationship among foster carers, biological parents, and foster children. It refers to the current 30 hours compulsory training program of foster parents, emphasizing the necessity of a further specialized comprehensive training, on the ground that well prepared foster carers can better face the complexities of fostering. There is also an imperative need for ongoing support for foster parents, which will be provided in the context of social workers’ supervision to meet the behavioral and emotional challenges presented by foster children. The study investigates the potential hindrances faced during the child's placement within the foster home and the vital role social workers play in addressing these difficulties. It delves into the backgrounds of biological parents, foster carers, and foster children, examining the psychological issues and trauma they may confront. The paper highlights the paths of creating an emotional bond, trusting relationships, amongst the child and his/her foster parents and contact issues between foster and biological parents, asserting that these elements are crucial for the child's well-being and his/her integration into the foster family. Moreover, it recognizes the need for policy makers and practitioner’s collaboration and interdisciplinary approaches within the foster care system. The study concludes that well-structured support, the empowerment of children through resilience building, and a stable legal framework are foundational to successful application of the institution of fostering. It encourages future research in the form of longitudinal studies, the evaluation of training models, and cross-national comparisons that include Greek foster care organizations to ameliorate the effectiveness of foster care system. The research incorporates theoretical and research studies articles as well as selected books in the field to underline the importance of evidence-based practices in advancing the application of the institution of foster care as well as the experiences of both foster care children, biological and foster parents.
Role of Structural and Functional Whole-Brain Imaging in the Assessment of Preterm Infants
Authors: Rege Omkar
Published: March 2024

Approximately one in ten infants are born preterm, with each bearing some form of underdevelopment, ranging from behavioral problems to muscular disorders. These developmental issues can lead to increased healthcare costs, permanent injury, and even death. However, with the growth of whole-brain imaging, scientists have found new ways to study premature infants. Leading this overlapping of fields are magnetic resonance imaging (MRI), functional MRI (fMRI), diffusion MRI (dMRI), electroencephalography (EEG), and magnetoencephalography (MEG). These technologies give insight into a premature infant’s disposition to lower brain mass, suboptimal learning, and neuropathological lesions. Although every technique has flaws, whether it be in its spatial or temporal resolution or just fundamental limits, each has its own unique benefits. In this paper, we will observe how different techniques are used to study the neurological health of premature infants.

Differentiated Instruction - Motivation and Academic Achievement Across Distinct Disciplines
Authors: Chenyang Yuhui
Published: March 2024

Differentiated instruction (DI) is gaining popularity as a pedagogical method/method of teaching, with the move towards inclusion. Research indicates that DI’s effects on student performance and engagement are significant and positive, though there are some inconsistencies when it comes to specific findings. This study sought to investigate the extent of the effects of DI on student academic performance and motivation across two courses from distinct disciplines - English and Chemistry - in a chosen international school in Beijing, China. The study adopted a quasi-experimental research design using a sample of 32 high school students. Anonymized data on motivation were collected using a validated researcher-developed Academic Motivation Scale (AMS), while academic achievement was measured by standardized testing scores. Analysis of Variance (ANOVA) was used in analyzing and presenting data collected for the study. Results indicated that the differentiation was effective at increasing motivation to a statistically significant extent, in line with the literature. However, student academic performance as measured by test scores was not shown to have been significantly influenced by DI. It was also found that the effects of DI did not significantly differ between the two chosen courses. The results imply that in this study, DI’s superiority in one particular subject/discipline has not yet been established, but future studies can be conducted in a more substantial time frame which may potentially lead to more significant results.
The Fragile, Constructed, and Repeated: A Study of Memory Practices in the Art that Impacts Us
Authors: Mo Sophie , Shanks Michael
Published: March 2024

Art affects us in ineffable ways, and a large part of it is its ability to retrieve and manipulate memory, or put simply, memory practices. Artists work with memory: whether it be personal memory, shared memories, or common memories. There are many different frameworks to discuss and analyze such art. This paper will use the theatre archaeology framework to discuss and uncover the techniques used by three separate artists: Sarah Sze, Lynn Hershman Leeson, and Ragnar Kjartansson. Through analyzing three of each of the artists’ principal works, theatre archaeology provides an answer to the factors of an effective and compelling piece of art.
School’s Role in Obesity Prevention
Authors: Murr Charlie , Wells Sean
Published: March 2024

Fast food, advanced transportation, and behind the desk jobs characterize the lifestyle of the majority of Americans. Unfortunately, this lifestyle has resulted in one of America’s worst epidemics: obesity. In 2000, over 15% of Americans aged 6-19 were obese/overweight. In 2020, this statistic grew tremendously, when obesity was prevalent in 22.2% of people aged 12 to 19-years old in America alone (CDC 2022). In an effort to battle obesity, government and societies have turned to schools to be the firsthand prevention for the pandemic. This has been evident in past national and state legislation regarding what students eat at lunch. However, the focus of these actions has been on school food, but the importance of exercise within schools has been overlooked. Using a survey, the aim of this research is to analyze the exercise patterns of high school students in an Orange County Public School. The findings conclude that about 30% of students are getting the recommended amount of exercise through the school each day, but most of these students are doing so through extra-curricular sports. Therefore, the students who are getting enough exercise are doing s because they want to, not because the school is making them. Consequently, schools need to play a bigger role in challenging obesity by requiring more mandatory exercise for students.

Authors: Katragadda Asrith , Lu Duo
Published: March 2024

This research paper presents a method for analyzing driving using aerial drone images of traffic scenes. By applying principles of motion and calculus we introduce an approach that provides insights into driving dynamics without relying on complex vehicle markings or annotations. This method offers a perspective on road behaviors, allowing for an understanding of potential risks and ultimately enhancing road safety. In our experiment we examined a series of drone images capturing traffic scenarios. We provided a procedure and demonstration of applications of physics and calculus to reconstruct traffic scenes.  We constructed a trajectory mechanism that uses all of said concepts to form a concrete plan to reconstruct scenes, using real drone footage with bird’s eye view. The combination of concepts with aerial image analysis showcases the potential for objective and data driven assessments of reckless driving behaviors. Overall this paper serves as a starting point for advancements, in utilizing models to analyze traffic patterns. It contributes to promoting road practices and improving transportation management through evidence based approaches.
Fluorescent Lighting’s Impact on Academic Performance of High Schoolers
Authors: Aghabi Emily , Teeling Kayla
Published: March 2024

Fluorescent Lighting maintains its prominence in schools, offices, and businesses across the country due to its cheapness and effectiveness, though its nature can lead to headaches, eye discomfort, or even inability to focus. While previous researchers have delved into how this lighting affects elementary-age students, college students, and adults outside of schools, high schoolers spend far more time under fluorescent lighting averaging 7 hours a day, 5 days a week, four weeks a month, and 10 months a year. Furthermore, this extended exposure can result in more severe effects of fluorescent lighting, leaving students at a disadvantage in the classroom. Utilizing an online IQ test and symptom pre/post-tests, high school students were examined under fluorescent lighting, natural lighting, and darkened lighting with their IQ score, time needed to complete the exam, and symptom prevalence measured. The average IQ score for fluorescent lighting was 123.4 whereas for the natural lighting trial, the average score was 130.4 and darkened lighting had an average score of 127.4, and 67% of scores under fluorescent lighting were 125.5 or below whereas natural lighting demonstrated 83% of scores being 125.5 or above (125.5 was the median number out of the entire data set). Similarly,  91% of participants under fluorescent lighting needed 11 minutes and 23 seconds or more to complete the test whereas 83% of participants under natural lighting needed 11’23” or less to complete the test (11' 23” was the median number out of all the data collected).

Authors: Sugianti Sugianti , Prasetyo Angga , Triananda Agnes
Published: March 2024

Catfish is a type of freshwater fish that is in great demand among people because it has high nutritional value. The high demand for catfish on the market is a promising business opportunity. The relatively fast maintenance period makes this cultivation much in demand. Management of a catfish farming business requires good strategy and planning so that the business process can provide optimal profits. Appropriate management practices, good planning can predict crop yields with minimal error rates. Based on past data from catfish farming businesses, catfish pond production results are influenced by several factors including pond area, number of seeds, and amount of feed. The catfish cultivation management system produces predictions of catfish harvest but ignores weather conditions, natural disasters and infectious diseases. The method used in crop yield prediction management is the Tsukamoto Fuzzy inference system. The Tsukamoto method applies monotonous reasoning and rules are built using expert knowledge, enabling the system to be able to conclude and manage predictions of catfish harvest based on data regarding pond size, number of seeds and amount of feed. System testing using 10 data shows prediction results obtained through manual calculations and system calculations, resulting in identical results. Further testing uses the white box method to ensure that the data implemented in the Tsukamoto fuzzy management system accurately produces logical decisions. Hence, it can be concluded that the management system using the Tsukamoto method is able to show effective performance in predicting harvest results based on data on pond area, number of seeds and amount of feed consumption. This management system is expected to be able to provide recommendations for catfish cultivation business planning for the community.
Drinking Indigenous Beverages in Africa: The Case of the /Bili-bili/ of the Lele People of North Cameroon
Authors: Moffor Exodus Tikere , Bienvenu Ami
Published: March 2024

Every human society produces beverages but the raw materials and procedures of production may differ from one society to the next. Some societies especially in Africa use maize, others use millet while others use guinea corn for their production. There are certain beliefs surrounding the manufacture and use of each beverage. The /bili-bili/ of the Lele people of north Cameroon is a good example of local beer produced from millet, red millet and sorghum. This local liquor is produced mostly by the female folk and its production goes through a number of processes. The drink like any aspect of culture fulfils a specific function in the Lele community. It used to be manufactured from millet, red millet and sorghum alone but with time, there are women who produce it with red millet and maize. The main research question of the article is: what are the functions of the /bili-bili/ to the Lele man in particular and the community in general? The secondary research questions are: what is the cultural significances of the /bili-bili/ to the Lele people? and what are the factors that have caused changes in the production consumption of this indigenous liquor? The objectives of this article is to examine the place of bili-bili in the lives of the people and in the society as a whole. The paper also seeks to find out the symbolism of this drink and the reasons behind the changes in the production and utility of the bili-bili. The authors of this paper used the qualitative method to collect data. This data was analyse soon after collection was over and interpreted using the theories of cultural ecology (to demonstrate how millet and sorghum, all natural products are employed to produce a cultural drink, bili-bili), functionalism (employed to show the roles of the locally brewed drink in the lives of the Lele people and the Lele community) and symbolic anthropology (used to illustrate the cultural significance of the bili-bili to the Lele people. Bili-bili symbolises a bond as many youths like adults meet and share from a single calabash or bucket. This drink is not only a source of livelihood to many households, it portrays the belief system of the Lele people in particular and that of the northerners in general. The indigenous drink /bili-bili/ is a drink which portrays the cultural identity of the people. If valorised, it will continue to be a major source of livelihood to many families.

Published: March 2024

Research has been carried out on the effect of pH, fermentation time and yeast concentration on bioethanol production through hydrolysis using a CEM (Ceramic Elekctromagnetic Microwave) synthesizer and bioethanol production from Ulva reticulata seaweed. Ulva reticulata seaweed contains carbohydrates in the form of heteropolysaccharides such as glucose, arabinose, ramnose and xylose which are very abundant and suitable for conversion into bioethanol because the people of Timor Island do not use them as food. The carbohydrate content of Ulva reticulata seaweed can be converted into hexose and pentose sugars (glucose, arabinose, ramnose and xylose) through hydrolysis using 3 types of acid catalysts, namely hydrochloric acid (HCl), sulfuric acid (H2SO4) and nitric acid (HNO3). Fermentation was carried out with S. cerevisiae concentration variation of 6; 8; 10; 12 % (v/v) and fermentation time variation of 3; 5; 7; 9 days and a pH variation of 4; 4.5; 5; 5.5 at a temperature of 30 °C. Reducing sugar characterization used the Dinitrosalicylic acid (DNS) reagent, sample surface texture analysis was carried out using Scanning Electron Microscopy (SEM) and ethanol characterization used Gas Chromatography-Flame Ionization Detector (GC-FID). The results of surface texture analysis before and after hydrolysis experienced significant changes. Optimal conditions for hydrolysis of Ulva reticulata seaweed using sulfuric acid (H2SO4) combined with a CEM synthesizer at an acid concentration of 3 % (v/v) with irradiation power of 200 watts for 50 min at a temperature of 150 °C, produced reducing sugar of 97.06 g/L. The results of GC-FID analysis indicated that bioethanol concentration obtained at optimal conditions of pH 4.5 was 42.32 %, S. cerevisiae concentration was 12 % with a bioethanol content of 42.53 % at a fermentation time of 5 days. This research is expected to provide information for researchers and industry to overcome world energy problems and environmental pollution through Ulva reticulata waste.

GRAPHICAL ABSTRACT
Sob o governo dos outros: dominação republicana e hierarquia social
Authors: Petroni Lucas
Published: March 2024

O artigo analisa a concepção neorrepublicana de dominação como uma resposta possível para o que há de moralmente objetável em relações nas quais vivemos sob o poder de outras pessoas. O objetivo da análise é comparar a noção de dominação republicana, tal como concebida pelas teorias neorrepublicanas da liberdade (Skinner, Pettit e Lovett), com o que teorias igualitárias da justiça têm denominado de problema da subordinação social (Neuhouser, Kolodny e Anderson). Procura-se destacar no artigo os ganhos que a ênfase em formas injustas de subordinação social traria para a compreensão de casos injustos de governo interpessoal.
Concepções de Liberdade em Hegel, Honneth e Marx
Authors: Tidre Polyana
Published: March 2024

O presente artigo tem por objetivo a abordagem de alguns aspectos das concepções de liberdade em Hegel, Honneth e Marx, buscando defender a tese de uma contraposição fundamental entre os dos primeiros e o último. Argumentarei que, enquanto Hegel e Honneth vinculam os problemas ligados à economia de mercado capitalista ao fracasso da mesma em realizar suas próprias promessas normativas – dentre as quais, e como principal, a realização da liberdade –, Marx, ao contrário, entende ser justamente o bom cumprimento dessas promessas o que garante a produção e reprodução das relações de exploração – por conseguinte, de não-liberdade, de desigualdade e de expropriação – que caracterizam a economia de mercado capitalista. A fim de fundamentar a contraposição dessas duas concepções, estruturo o texto da seguinte maneira: primeiro, empreendo uma abordagem do conceito de liberdade em Hegel, sobretudo a partir da Filosofia do Direito, mostrando como ele é forjado a partir de sua crítica a outras concepções de liberdade. Em seguida, abordo a análise feita por Honneth em O direito da liberdade da relação existente entre liberdade e mercado, mostrando o que ele entende por “liberdade social”. Por fim, exploro alguns pontos da crítica feita por Marx em O capital a uma certa abordagem da liberdade que, tratada unicamente no âmbito do “mercado” ou da “esfera da circulação”, impediria ver como a realização da liberdade seria, de maneira aparentemente contraditória, condição da produção das relações de exploração e da contradição capital-trabaho necessariamente ligadas à dinâmica característica dessa economia de mercado.

Study Design: Cross-sectional study.
Place and Duration of Study: Department of Gynaecology and Obstetrics, Pak-Emirates Military Hospital, Rawalpindi Pakistan, from Jun to Dec 2022.
Methodology: A total of six hundred and ten (n=610) patients were in the study. The variables studied while observing the outcome included indication of Caesarean section in the previous delivery, birth weight of the baby, overall outcome and post-operative maternal complications.
Results: The mean age of the participating patients was 24.44±3.89 years. Of the 610 patients, 278(45.6%) delivered successfully via vaginal delivery after a previous Caesarean section, while 332(54.4%) had to be delivered again via repeated Caesarean section. Overall outcome in both groups revealed 331(99.7%) patients were delivered by Caesarean section, with 01(0.3%) patients landing in a ruptured uterus in the Caesarean Section Group.
Conclusion: Previous history of normal vaginal delivery, increased parity and birth weight less than 3 kg have a better chance of a successful Vaginal Birth after a Caesarean section in selected patients resulting in fewer complications and decreasing the overall Caesarean section rate.
The use of Instagram as a communication tool in the Durban fashion industry
Authors:   , Ngcobo Thandeka
Published: March 2024

Over the years, social media has become an imperative platform in the fashion industry for testing new marketing strategies and monitoring trends. There are thousands of luxury and high street fashion brands around the world that are present online. Despite the fact that fashion brands have unilaterally set their polished brand images through traditional media such as television channels and magazines, social media serves as a very powerful tool for promoting and sharing fashion information to both industry and people (Ha, Kwon, Cha and Joo 2017:418). Undeniably, Instagram is not only used as any other social media platform, but also as a marketing tool for local fashion brands. There are numerous phenomena of Instagram marketing. However, there is still a lack of clarification as to why these phenomena occurred. The aim of this study was to determine the use of Instagram as a communication tool in the Durban Fashion industry. The primary objective of the research was to examine the influence of Instagram as a communication tool in the Durban Fashion industry. The study followed a quantitative research method in order to accomplish the set objectives. Non-probability sampling was used in recruiting participants. Purposive sampling technique was utilised to generate the sample population. Fashion brand owners in Durban who use Instagram as a communication tool were the population targeted by this study. The researcher was able to get a 91.5% response rate as 119 questionnaires out of 130 were collected. The study used the Statistical Package for the Social Sciences (SPSS) version 24.0 for Windows to analyse the data. The study revealed that Instagram is an effective communication tool that fashion business owners can benefit from, if used strategically. Furthermore, the findings revealed that Instagram is giving fashion business owners a platform to showcase their best offerings; communicate with their target audience; and increase brand awareness. One of the recommendations was that fashion businesses who are not using Instagram as a communication tool to start using this social media platform. Communication through the use of pictures and videos seems to be a new strategy for marketing. The study also recommended that it is important for fashion owners to prioritise engagement with their target audience on Instagram in order to build friendly relationships and increase the number of followers.

Education is one of Indonesia's goals as stated in the fourth paragraph of the 1945 Constitution. However, the decentralization problem of education through transformational schools found various obstacles. This study aims to explore the problems of decentralization of education of the Freedom to Learn program through transformational schools spread throughout Indonesia. This study used the literature study method obtained from literature and books and with VOSViewer software which analysed 2.339 social articles discussing decentralization. The results of the research showed that decentralization implementation of education through transformational schools met obstacles such as inadequate facilities and many teachers are struggling to use technology, so the decentralization process is not maximal. The researchers suggest that the government should provide space for policy targets from lower levels spread throughout Indonesia so that the education decentralization process can run.

Published: March 2024

De par sa complexité, le comportement des ouvrages renforcés par géosynthétiques est parfois évalué par des modèles numériques. Dans ce chapitre, deux familles de méthodes numériques sont présentées : la modélisation numérique continue et la modélisation numérique discrète. Les domaines de prédilection de ces méthodes, leurs limitations et leur performance sont discutées. Des applications à des expérimentations de laboratoire ou à des ouvrages instrumentés sont présentées à des fins d’illustration.

Abstract. In this work, an optimized protocol to generate an expansion-type liquid clouds with and without UV-visible light irradiation conditions for simulation chamber studies is presented. Sensitivity of the process to key parameters such as initial relative humidities, temperature inhomogeneities, droplets lifetime or seed particle number is illustrated. The obtained clouds have shown that not all seeds particles were always activated and so an iterative numerical method has been re-designed to separate cloud droplets from non-activated seed particles during data analysis allowing the characterization of the cloud droplet formation properties without CCN counter data. Two types of experiments, clouds without irradiation (N-IC) and under UV-visible light irradiation conditions (IC), have been conducted in the CESAM multiphase atmospheric chamber. Measured cloud droplet lifetimes were in good agreement with atmospheric droplet lifetimes. The achieved supersaturation in the cloud was mostly sensitive to the initial relative humidity in the chamber. The comparison between the cloud formation pattern of N-IC and LC was also investigated. Under illumination conditions, the generated clouds clearly showed a gradual activation of seed particles into droplets and thus of the microphysical properties like LWC and droplet concentration, while under dark conditions, clouds faced a flash activation of seed particles. Because this phenomenon may also impact the air/water partitioning of semi-volatile compounds, and it should be considered for further studies, especially in further multiphase photochemical studies implying water-soluble volatile organic compounds in the CESAM chamber.

Abstract. Airborne dust aerosols impact negatively the climate, ecosystems, air quality, and human health. To mitigate these impacts, it is crucial to identify their three–dimensional spatiotemporal distribution, transport pathways and driving factors. In this study, the three–dimensional spatiotemporal variations and distribution of dust aerosols in China from 2007 to 2021 were first analyzed using multiple dust datasets, including Modern Era Retrospective Analysis for Research and Applications version 2 (MERRA–2) dust aerosol optical depth (DAOD) data, ultraviolet aerosol index (UVAI) data from the Ozone Monitoring Instrument (OMI), and the Vertical Feature Mask (VFM) product of Cloud–Aerosol Lidar with Orthogonal Polarization (CALIOP). Also, the transport pathways and potential source regions for dust haze in principle provincial capital cities of West and North China in spring were identified using the Hybrid Single–Particle Lagrangian Integrated Trajectory (HYSPLIT) model and Potential Source Contribution Function (PSCF). Additionally, DAOD variations over different land cover types and the impacts of meteorological driving factors were discussed with geographic detectors. Results indicate that: (1) The multi–year average of DAOD in China from 2007 to 2021 was 0.076. A mutation in annual average DAOD occurred between 2010 and 2011, with an insignificant increasing trend between 2007–2010, a downward trend between 2011–2021 and a significant downward trend between 2014–2017. (2) The Taklamakan Desert exhibited the highest DAOD for the entire China during spring throughout the years, with DAOD values ranging from 0.4 to 0.6 and UVAI values exceeding 2.0. The highest frequency of dust occurrence in the northwest and northern regions is at an altitude of 2–4 km in spring and summer, and of 0–2 km in autumn and winter, while it is at an altitude of 4–6 km for the Qinghai–Tibet region. (3) The dust transport routes for the provincial capital cities can be primarily divided into: western, northwestern, northern, southwestern, and local. Northwest cities are notably affected by dust from surrounding deserts. Dust originating from the Qaidam Basin and the Hexi Corridor can be carried further downwind to inland cities, such as Xining and Lanzhou. A dust backflow was found in Beijing and Tianjin. Moreover, the discussion revealed that barren and cropland had the highest DAOD and additionally precipitation, evaporation, and soil moisture were identified as the strongest driving factors affecting dust aerosol variations. The combination effect of precipitation and temperature had the highest explanatory power, ranging from 0.72–0.84, followed by 0.75–0.81 for precipitation and U10m wind speed and 0.67–0.75 for temperature and evaporation.
