Migration and the Role of Diaspora Communities in Sustainable Development
Authors: Susan Doofan Albert-Makyur
Published: March 2024

This study posits that Diaspora Communities have the potential to serve as catalysts for sustainable development due to their distinct characteristics, enabling them to contribute substantially in both their adopted nations and countries of origin. It examines the complex connection between migration and sustainable development, particularly emphasizing the duties diasporas play through diverse means such as financial remittances, knowledge transfer, entrepreneurship, philanthropy, and cultural exchange within their respective global communities. This research presents a novel methodology for analyzing diaspora-driven development, drawing on a comprehensive range of primary and secondary data sources. Findings reveal that without a transparent framework for involvement, collaboration and advocacy, the connections between expatriate communities and their countries of origin tend to be temporary and limited to specific sectors, events, or locations. The study recommends an effective policy framework for the diaspora demographic database to enhance information accessibility and skills pool tracking and an improved formal framework to support Diaspora remittances and projects and strengthen the role of Diaspora Associations for achieving UN Sustainable Development Goals and consistent collaboration/relationship between these entities.

Published: March 2024

The study examined the factors influencing Households' choice of waste management strategies in Lagos State, Nigeria. A multi-stage sampling procedure was used to select respondents for the study. In the first stage, two states (Lagos state and Ogun state) were purposefully selected based on their well-organized waste management systems, relatively advanced waste management arrangements, and close proximity. In the second stage, three LGAs were purposely selected from the Lagos state, while three LGAs were selected in Ogun state, considering well-organized waste management systems. In the third stage, a stratified sampling technique was used to select four communities from each LGA into two different strata: high-income and low-income. In the fourth stage, fifteen respondents were selected using a systematic sampling technique. In all, 360 respondents were used for the study. Primary and secondary data collected from 360 respondents were analyzed using descriptive statistics, multi-dimensional poverty index, multinomial logit, and regression model. The average age of the household head was 47 years, which implies that the respondents were mostly middle-aged people who were still within their economically active age group. This is expected to positively influence the respondents' decision-making as they would be making sound decisions regarding waste management since they are likely to be more exposed to different health-related information. The income distribution revealed that the household head earned an average income of N109, 211.00. It was also revealed that the respondents earned a minimum of N10, 000.00 and a maximum of N3, 500,000.00. The result revealed that the majority of the household heads earned more than the N33,000.00 monthly minimum wage approved by the Federal Government of Nigeria, which indicates that they are average-income earners and will consequently enable the household heads to make rational decisions on their choice of waste management. It was revealed that about 52.6% and 35.9% of the respondents in Lagos and Ogun States, respectively, who are below the poverty line, used PSP, while about 28.9% and 34.1% of those who are non-poor or above the poverty line used the PSP. Years spent in schools, waste disposal cost, and disposal frequency were the major factors influencing households' choice of waste management strategies in south-west Nigeria. This policy should promote new healthy waste disposal methods like PSP, which the poor can afford, while phasing out the old and unhealthy methods like open dumping and burning, which still predominates in the study area and most parts of the developing countries.

Published: March 2024

The established and approved vision and mission of the master of management study program is certainly followed by a process of socializing the vision and mission through various programmes, including: • Socialization with lecturers through regular meetings; • socialization with students through student activities and lectures; • Socialization with students through meeting activities at the beginning of college admission; • Socialization with stakeholders and broader audience through various channels such as the study program website, brochures and banners, YouTube videos and radio broadcasts. The purpose of this study is to know and analyze the understanding of the academic community, graduate users, and partners of the master of management study programme at Trisakti University in Indonesia, regarding the implementation and socialization of its Vision and Mission during year 2022-2023.This research is a descriptive study that can provide an overview of the perceptions of the academic community, graduate users, lecturers and partners in the Master of Management Program. This study uses primary data by circulating questionnaires to respondents. The sample of this research is the academic community of the Master of Management Program at Trisakti University, where respondents came from active students, lecturers, academic staff and alumni. The number of respondents who filled in the questionnaires properly and completely was 163.Based on these findings, this study concluded that the socialization implementation of vision and mission is becoming more important and significant to the sustainability of the study program in universities to prioritize and optimize their personnel and financial resources to achieve outstanding academic results. Even though the results of all of the indicators have a high success rate, the socialization of vision and mission needs to be done regularly and effectively through various ways and channels to make sure that the message is delivered and conveyed well.
Dance, Movement and Songs as Mechanisms for Promoting Social Control and Social Cohesion: A Study of Kpashimo in Teshie Homowo and Fontomfrom in Adukrom Akuapem, Ghana
Authors: Jennies Deide Darko
Published: March 2024

The claim that dance is present in practically all events in the Ghanaian life cycle is not entirely mythical but indeed verifiable in most cases. Festivals and funerals are social events that are held in public to express, reflect and strengthen community social relationships, as well as celebrate the lives of significant relations who have died. They are two of the experiential rites of passage in the Ghanaian culture and are observed through the use of special forms of language, dance and music. These art forms have important roles to play in Ghanaian traditional events, their main function being that they engender unity and cohesion and discourage deviant and irresponsible behavior within the society. Kpashimo is usually celebrated as the climax of the Teshie homowo festivities. Fontomfrom, in addition to being the name of an Akan drum, is also the name given to an important Akan ceremonial dance. This paper examines the socio-cultural significance and relevance of the kpaashimo and fontomfrom dances and their utility in the Teshie and Adukrom social contexts, respectively. The study was done using the functionalist approach, utilizing dance as a medium to stimulate social control, cohesion, and unity in two geographically different cultures. Despite the disparate cultures, dance was used successfully to achieve the required goals and, in essence, validate the claims about the universality of dance in the Ghanaian context. It was a qualitative research employing essentially observation and interviews. Photos and videos were also used for efficient illustration and accurate recall.

Published: March 2024

Distúrbios genéticos, metabólicos ou ambientais podem causar malformações do sistema nervoso central (SNC) durante o desenvolvimento cerebrospinal. As infecções congênitas fazem parte das causas ambientais, especialmente o citomegalovírus (CMV) e o vírus Zika. Relatamos um caso de uma criança com malformação congênita do SNC, com suspeita de infecção por CMV. O uso de valaciclovir durante a gravidez, sem coleta para avaliação do líquido amniótico devido à idade gestacional avançada, pode ter impedido o isolamento do vírus no recém-nascido e a identificação da causa da malformação do SNC. Discutimos aqui as dificuldades encontradas para um diagnóstico de certeza para a criança em questão. Mesmo em países desenvolvidos, as infecções congênitas ainda são um grande desafio diagnóstico. As oportunidades perdidas de investigação devem ser evitadas para que a etiologia seja reconhecida precocemente e, se possível, tratada.

Data Fusion of Wing Pressure Distributions Using Scalable Gaussian Processes
Authors: Anhichem Mehdi , Timme Sebastian , Castagna Jony , Peace Andrew J. , Maina Moira
Published: March 2024

Aircraft design requires a large volume of aerodynamic data to characterize various flight conditions throughout the aircraft’s flight envelope, and the data are typically obtained through wind tunnel testing and numerical analysis. Data acquisition can be costly and inevitably entails multiple sources of uncertainty. Data fusion techniques aim to bring together the strengths and mitigate the limitations of data from various information sources. A multifidelity data fusion framework employing Gaussian process regression is adopted herein and applied to the surface pressure data of a large aircraft wing model. The modeling approach is non-hierarchical in that there is no established hierarchy of accuracy among the information sources. Scalability issues arising from the large volume of data required for the study of pressure distributions are overcome by using an approximate Gaussian process regression based on stochastic variational inference, enabling the data fusion framework to be applied effectively to industry-relevant analysis and design challenges. The approach is demonstrated for a high-dimensional data set generated through wind tunnel testing in an industrial setting and numerical analysis.
Unsteady Lift Produced by a Flat-Plate Wing Translating Past Finite Obstacles
Authors: Shah Karan A. , Ringuette Matthew J.
Published: March 2024

The unsteady lift of a high-angle-of-attack, flat-plate wing encountering finite-length obstacles is studied using towing-tank force measurements and flow visualization. The wing translates from rest and at 1 chord traveled interacts with a rectangular channel, ceiling, or ground. The angle of attack, obstacle length, and height to the obstacle are varied. As the channel gap height decreases, circulatory-lift peaks attributed to leading-edge vortices (LEVs) become larger, and for the second peak onward occur earlier, from wing blockage enhancing the flow speed. Larger and earlier LEVs are visualized, supporting this, as are secondary vortices off the channel. The lift reduces while exiting a channel, being lowest afterward if exiting during a lift peak. For ceilings, the first circulatory-lift peak increases for smaller LE-to-ceiling gaps, but for 0.5 chord gaps or less, later maxima are below the no-obstacle case yet still earlier. For grounds, with lower wing height the first circulatory-lift peak is larger but the second peak’s behavior varies with angle of attack, and lift decreases near the ground end. Grounds affect peak timing the least, indicating less influence on the LEV. The lift rises slightly ahead of channels and ceilings, and often lowers before channels and grounds end, providing warnings.

The research revision of materials from the 1932 and 1934 collections of the world-famous geoarchaeological site Malta, stored in the Kunstkamera (St. Petersburg), was carried out in the spring of 2023. The purpose of the analysis was to identify lithic artifacts with marks of Aeolian corrasion as part of the study of the corraded industries of the Angara-Belsk geoarchaeological district of South Angara. As a results, 3 663 artifacts were examined, among them 71 corraded items were identified. The results present the corraded component of Malta's lithic industry practically does not differ from the «classical» cultural layers by technical, typological and petrographic features. But unique type of the point with ventral base thinning has no analogue in «classic» assemblage. And if previously these artifacts were interpreted in a regional context as cultural markers of the Initial Upper Paleolithic, now it is proposed to consider them as an element of the Gravett (?) technocomplex in Malta and one more proof of European-Siberian cultural link in author's opinion.
Child Justice System in ‘Uqubat Dropping of Child Sexual Abuse of Children
Authors: Fachruddin  , Khalid  , Yadi Harahap
Published: March 2024

Settlement of criminal cases against children who conflict with the law must be oriented towards the principle of "The Best Interests Of The Child," namely the child's best interests. The Law on the Juvenile Criminal Justice System exists as an embodiment of this principle, prioritizing Restorative Justice to create an agreement on the settlement of criminal cases. With its regional autonomy, Aceh Province has the independence to make its own rules in the form of Qanuns, including Qanuns to resolve criminal cases committed by children, one of which is Qanun number 6 of 2014 concerning Jinayah Law. However, there was disharmony between the Juvenile Criminal Justice System Law and the Jinayah Law Qanun in the trial process and the type of verdict handed down. As in the criminal case of sexual abuse committed by a child, In the Jinayah Law Qanun, there is a separate procedure for determining a sentence for a juvenile offender, which is different from the sentence handed down when referring to the Law on the Juvenile Criminal Justice System. Another example is that diversion is not recognized in the Qanun Jinayah Law, and it becomes an obligation when referring to the Juvenile Criminal Justice System Law. This contradiction also affects the quality of the decisions issued by judges, in this case, the judges of the Syar'iyah Court.
The Implementation of Dwangsom in the Execution of Hadhanah Matters and its Relationship to the Ultra Petita Basis
Authors: Firdawaty Linda , Mahmudah Siti , Isa Rozana
Published: March 2024

This article aims to examine the reasons why dwangsom is urgent in hadhanah cases and how it is implemented in hadhanah execution cases and its relationship with the ultra petita principle.  This article is empirical normative legal research with qualitative descriptive analysis method. The urgency of dwangsom in hadhanah cases is an effort to provide psychological pressure so that the defendant wants to carry out the judge's order voluntarily, namely handing over the child who is the object of the case. If the defendant does not hand over the child as the judge's decision, then the defendant must pay dwangsom. The institution of dwangsom is not widely known to the public, but dwangsom is an appropriate and effective solution because the surrender of children cannot be done through forced execution.  Dwangsom can be implemented in hadhanah cases if the plaintiff submits a dwangsom application. The petition must also explain the chronology of the plaintiff's reasons for requesting dowry. If dowry is not submitted in the petita, then the judge is not authorized to decide dowry, because granting dowry without a request from the plaintiff is an ultra petita action.

This article is about the implementation of the principles of non-refoulement related to refugee protection in Indonesia, the problem is that Indonesia still has not ratified the 1951 convention and the 1967 additional protocol, this has an impact on refugees who come to Indonesia. The purpose of this article is to see how the implementation of the principles of non-refoulement in Indonesian legislation, then to analyze the challenges and dynamics of refugees in Indonesia. The method used in this article is normative method, the type of analysis used is qualitative, the type of this article is library research. Then the results of this article found that the complexity of global problems related to refugees requires serious attention from the international community. Although Indonesia has not ratified the 1951 Convention and 1967 Protocol, the commitment to protect and assist refugees remains a focus to fulfill international responsibilities. The principle of non-refoulement is one of the foundations of refugee protection that prohibits forced return. Although Indonesia already has a national legal framework related to refugee protection, the implementation of the principle of non-refoulement needs to be analyzed more deeply. This article is important because it provides a deeper understanding of the challenges and steps that can be taken to improve refugee protection in Indonesia. This paper fills the knowledge gap regarding the implementation of the principle of non-refoulement in Indonesia and is expected to provide suggestions and recommendations to improve the protection and implementation of the principle of non-refoulement of refugees in Indonesia.

Authors: Razida Razida
Published: March 2024

Due to students’ low interest in reading, the government addresses this issue by involving a literacy movement program in national curriculum. However, many students if not all prefer being on their phone to read a book. Therefore, instead of making students go against the use of their phone, the researcher takes advantage of learning through their phone. In this case the researcher suggests a way to support the literacy movement and ask students to use their mobile phone as a useful media to study by creating Instagram captions. Students upload photos on daily basis using English caption to describe the photos or the feeling of the students. Caption should provide context for the photography, inspire the audience and show brand personality. The participants of this research were 30 students of the XII grade of science program in senior high school. For the literacy program they should posted their Instagram caption every day for a week. This descriptive study aims at supporting the literacy movement for the senior high school students in order to improve their English language skill such as vocabulary, grammar, writing and reading. The researcher found out that creating Instagram captions is useful to improve the language competence.Keywords: Increasing Students' Participation, Literacy, Movement Creating, Instagram, Captions

Replacing liquid electrolytes with solid ionic conductors attracts increasing attention due to the potential of improved battery safety. Solid-state batteries show potential for further increased energy/power density by eliminating the use of packaging accessories for unit cells. Sulfide- and halide-based ceramic ionic conductors exhibit comparable ionic conductivity with liquid electrolytes. These materials, however, are inherently brittle, making them unfavorable for applications. Here, we report a mechanically enhanced composite Na+ conductor that contains 92.5 wt% of sodium thioantimonate (Na3SbS4, NSS) and 7.5 wt% of sodium carboxymethylcellulose (CMC); the latter serves as the binder and an electrochemically inert encapsulation layer. The ceramic and binder constituents were integrated at the particle level, providing ceramic NSS-level Na+ conductivity in the NSS-CMC composite, the more than five-fold decrease of electrolyte thickness obtained in NSS-CMC composite electrolytes provided a five-fold increase in Na+ conductance compared to NSS ceramic pellets. Resulting from the CMC encapsulation, this NSS-CMC composite shows increased moisture resistivity and electrochemical stability, which significantly promotes the cycling performance of NSS- based solid-state batteries, and improves ductility of the material. This work demonstrates a well-controlled, orthogonal process of ceramic-rich, composite electrolyte processing – independent streams for ceramic particle formation along and binder encapsulation in a solvent-assisted environment. This work provides insights into the interplay among the solvent, the polymeric binder, and the ceramic particles in composite electrolyte synthesis, and implies the critical importance of identifying the appropriate solvent/binder system for the precise control of this complicated process. Finally, the work also provides valuable insights into the potential of designing mechanically tailorable battery components via fundamental understanding of the effect of the constituents on the overall composite ductility.

Published: March 2024

Fluorocarbon oils are uniquely suited for many biomedical applications due to their inert, bioorthogonal properties. In order to interface fluorocarbon oils with biological systems, non-ionic fluorosurfactants are necessary. However, there is a paucity of non-ionic fluorosurfactants with low interfacial tension to stabilize fluorocarbon phases in aqueous environments (such as oil-in-water emulsions). We developed non-ionic fluorosurfactants composed of a polyethylene glycol (PEG) segment covalently bonded to a flexible perfluoropolyether (PFPE) segment that confer lower interfacial tensions (IFTs) between a fluorocarbon oil, HFE-7700, and water. Synthesis of a panel of surfactants spanning a molecular weight range of 0.64–66 kDa with various hydrophilic-lipophilic balances allowed for identification of minimal IFTs, ranging from 1.4 to 17.8 mN m-1. The majority of these custom fluorosurfactants display poor solubility in water, allowing their co-introduction with fluorocarbon oils and minimal leaching. We applied the PEG5PFPE1 surfactant for mechanical force measurements in zebrafish, enabling exceptional sensitivity.

Published: March 2024

Lentiviral Vectors (LV) are emerging tools for genetic therapies and novel cancer treatments. While effective, LV-based therapies have extremely large costs associated with their manufacturing and delivery. LV technology descends from human immunodeficiency virus (HIV), whose lipid envelope has been previously measured and shown to have a direct impact on its transduction efficiency. We developed a rapid, robust, and sensitive untargeted lipidomics pipeline to analyze novel LV biotherapeutic products and demonstrate its utility on HEK 293T packaging cells and concentrated culture media containing LV. The impact of 48 hours of LV production on the lipidome of HEK 293T cells was measured and compared to the expression of Vesicular stomatitis virus G protein (VSV G) over the same timeframe. 151 lipids were identified in HEK 293T packaging cells, 84 of which had fold changes with FDR-corrected P<0.05 compared to HEK 293T treated with media. It was found that fold changes with FDR-adjusted P<0.05 after VSV G expression and LV production were highly correlated (R2=0.89). Concentrating LV in culture media led to the identification of 102 lipids, half of which being determined to be unique LV virion lipids after subtracting the media lipidome. Our approach can be readily used to study the lipid dynamics of large-scale LV production and be rapidly translated into targeted methods to quantify individual lipid components or applied to other viral vector platforms.
LaMer Burst Nucleation -- A Graphical Interpretation of Microscopic Parameters from Macroscopic Measurements
Authors: Chu Daniel Benjamin Kasman
Published: March 2024

LaMer burst nucleation enables the production of monodisperse nanoparticles, such as quantum dots. This paper applies the Chu-Owen-Peters (COP) model of LaMer burst nucleation to the original sulfur sol data from Zaiser and LaMer and to CdS nanocrystal data from Owen and co-workers. I present a graphical interpretation to obtain critical nucleus size and growth rate from the dependence of total nuclei (produced in a burst event) on the solute supply rate. The sulfur sol data follows a linear relationship, such as that observed by Sugimoto and co-workers, but the COP model provides further information which puts a bound on the maximum critical nucleus size. Trends in the CdS data, which cannot be explained by a linear model, align well with the COP model. While more data would be necessary to determine the critical nucleus size precisely, we find a minimum bound on the critical nucleus size and a maximum bound on the attachment frequency at the peak of saturation. Finally, we demonstrate that such macroscopic information is sufficient to test theoretical models of nucleation kinetics by comparing the sulfur sol results to classical nucleation theory.
Food Composition of the Little Owl Athene noctua in Farmland Areas of South East Poland
Authors: Kitowski Ignacy , Pawlega Krzysztof
Published: March 2024

The feeding ecology of the Little Owl (Athene noctua) was studied in farmlands of southeast Poland, which is dominated by monocultural farms. 3065 prey dissected from pellets were collected at 13 pellet stations between 1999 and 2001 through 7 seasons in total. Mammals were found to dominate both in total number (54.3% of caught prey) and total biomass (93.0% of caught prey) while insects comprised 43.0% of the number, but only 1.1% of the prey biomass. However, the proportion of insects reached up to 62% in certain seasons. Coleopteran beetles dominated the insect fraction representing 98.3% of the number and 87.9% of the insect biomass. Our study also illustrated that in some seasons, the prey composition included taxa related to intensive agricultural management. The food composition of the Little Owls from the examined Polish sites is more similar to Eastern and Southern populations than to Northern and Western populations of Little Owls in Europe.

Published: March 2024

In this paper we present data relating to nest density and habitat use by the Lesser Grey Shrike Lanius minor in the Târnava Mare Valley, Romania, using both nesting tree parameters (microhabitat), and habitat parameters measured in a 100m radius around each nest. The density of nests was 0.96 per km². Average distance between nests was 768.4m. Most of the nests (94.1%) were found in poplars, in the region of the middle third of their trunk, especially at the terminal parts of the branches. The birds preferred open habitats, with extended arable field cover. Moreover, the tree and shrub cover were small in areas used for nesting. As poplars are the preferred nesting habitats of this bird, and are scarcely represented in this area, the protection of these trees is critical for conservation of the Lesser Grey Shrike.

The Evolution of US Bank Capital around the Implementation of Basel III
Authors: Siedlarek Jan-Peter
Published: March 2024

Following the Global Financial Crisis of 2007-2008, the capital standards for banks operating in the United States were tightened as US banking regulators implemented the Basel III framework. This Economic Commentary briefly presents the key elements of Basel III relevant to bank capital and analyzes the timing of the evolution of regulatory capital ratios for US bank holding companies during that time. It shows that, on average, banks’ capital ratios increased notably between 2009 and 2012, plateauing before the new rules came into force. While larger and better-capitalized banks increased capital ratios soon after the financial crisis, it took smaller and less-well-capitalized banks longer on average to start that process.
