Authors: Phan Thi Anh Nguyet , Mai Duc Nghia , Bui Van Duong , Do Van Phuc
Published: November 2024

This study examines the environmental and circular economy disclosures (ECED) level and factors influencing this level of 32 Vietnamese listed companies from 2018 to 2022. The content and frequency analyses are performed to determine the level of ECED, and regression analysis is to investigate the influencing factors. Drawing on a sample of 160 sustainable development and annual reports following the Global Reporting Initiative frameworks (GRI), the study evidenced that 32 listed companies paid great attention to the GRI 300 category (on environment topics) with the top three GRI standards 302 (energy), 307 (environmental compliance), and 303 (water and effluents), respectively. In addition, the Feasible Generalized Least Square method results showed that the companies with government ownership and Big4 audit services had a higher level of ECED. In comparison, larger companies had a lower disclosure level. Meanwhile, companies in the manufacturing sector with foreign shares and the independence of the Board of Directors did not affect the disclosure information disclosure level in the studied sample.

Published: November 2024

Improper waste management leading to contamination of groundwater resources is a global environmental issue. This study examined the physicochemical and toxicological characteristics of leachates and their effect on water quality around the dumpsite in Alimosho Lagos, Nigeria. Samples of water and leachates were collected from boreholes around the dumpsite. Physiochemical and toxicological characterization of water around the dumpsite was based on American Public Health Association standards. Seventeen physiochemical and heavy metals of leachate and borehole water samples were analysed. The result of the study shows that the temperature, odour, appearance and turbidity of the water in the study area were within the limits set by WHO.  However, the pH was below the WHO limits indicative of the acidity of the groundwater. The presence of Pb, Cr, and Cd confirmed leachate pollution. The contemporary effects confirmed the insignificant effect of the dumpsite operations at the groundwater source. Without a properly designed leachate series system, uncontrolled accumulation of leachates at the bottom of the dumpsite poses capacity infection dangers to groundwater resources. It is recommended that proper disposal of waste, in addition to implementing a higher sustainable environmental sanitation practice, is needed to ensure the safety of groundwater within the locality.

Authors: Ilaboya Idowu , Omosefe Eghosa , Ambrose-Agabi Esther
Published: November 2024

An integrated geophysical investigation of the second cemetery in Benin City was conducted with the view to determine the leachate flow direction and the geoelectrical layers that characterized the underlying aquifer. Eight vertical electrical soundings (VES) and two dipole-dipole profiling lines along two transverse sections were carried out. For the dipole-dipole profiling, ABEM Terrameter SAS 300C was employed, while the VES investigation utilized the Schlumberger array. The resistivity data collected during the field investigation were interpreted using DIPROWIN software version 4.01. Leachate plume was identified in the subsurface soil at a depth range of 5 to 20 meters. This was attributed to the soil porosity, aiding the infiltration of necroleachate. The VES results revealed four geoelectric layers: topsoil, lateritic soil, a weathered layer (composed of clay), and medium to coarse sand. The overburden exhibited a thickness range of 0.7762m to 0.8074m, resistivity ranging from 57.318Ωm to 2831.4Ωm, and depths ranging from 0.7762m to 1.5836m. The third geoelectric layer, identified as clay, had an average thickness of 11.48 meters at a depth of 13.06 meters, with a resistivity of 203.52Ωm. Apart from acting as a seal against the downward penetration of leachate, the clay also serves as a filter.

The Philippines has finally shifted to the K to 12 curriculum, with a senior high school program. This study explored the students’ lived experiences in Senior High school. A qualitative research design utilizing the 5-step Interpretative Phenomenological Analysis was used. Ten students from the 10 Senior High Schools in the Province of Siquijor, Philippines participated and were randomly selected and interviewed using a semi-structured interview guide. The following themes emerged: a) opportunities, b) challenges, and c) uncertainties. Likewise, the students had taken advantage of the opportunities to acquire future-ready skills, student-centered instruction, and adequate learning materials, and were mentored by high-performing teachers. There were challenges caused by the inadequacy of the facilities and the difficulty of the curriculum. Uncertainties about the support of the community and the tracks that the students wanted to pursue were also prevalent in their responses. Therefore, the implementation of the new curriculum has some positive developments and areas for improvement.

Dari Kuasa Kapitalisme Tradisional Menuju Kendali Kapitalisme Digital: Studi Kasus Desainer Grafis Online Otodidak di Dusun Kaliabu
Authors: Bangsa Petrus Gogor , Udasmoro Wening , Noviani Ratna
Published: November 2024

This study examines how self-taught online graphic designers in Kaliabu Village, Salaman District, Magelang Regency, Central Java, navigate the challenges and dependencies arising from digital platforms, particularly 99designs. Using a case study and in-depth interviews, the research reveals that, while digital technology appears to open new opportunities and empower individuals, it often reinforces control and exploitation within the digital economy. Most Kaliabu designers, lacking formal technical or creative education, leverage 99designs to access the global market, relying on self-developed skills to compete. Despite utilizing their informal capital, they are constrained by the platform's stringent rules. Although 99designs offers broad economic access, it imposes terms that limit designers' autonomy and innovation. Dependence on the platform forces designers to constantly adapt to its policies and face intense competition. The crowdsourcing system of 99designs, where projects are awarded through open competitions, exacerbates these dynamics, pushing designers to compete for every job. In the digital capitalist context, their informal capital often fails to overcome the platform's control and exploitation. This study highlights that while Kaliabu's self-taught designers can compete globally, they must navigate the balance between the freedom and control offered by digital technology. Digital technology enables participation in the digital industry but also presents challenges of control and exploitation that need addressing.
Equal Despite Different Entitlements? M.C. Piepers’ Ambiguous Conceptualization of Legal Equality (1898)
Authors: Linde Otto , Legene Susan
Published: November 2024

In ‘Gelijkstelling van Vreemde Oosterlingen met Europeanen’ (‘Legal Equation of Foreign Asians with Europeans’), published in 1898 in Tijdschrift voor Nederlandsch-Indië, the liberal intellectual M.C. Piepers argued against the legal equation of the resident Japanese subjects in the Netherlands Indies with the Europeans. To make such equation happen, Parliament in the Netherlands discussed a change in the Law in order to alter the provisions with respect to the binary colonial distinction between Europeans and all other people in the Netherlands Indies as laid down in article 109 of the ‘colonial constitution’ (‘regeringsreglement’) of 1854. The change was needed for the 1896/1897 trade-agreement between the Netherlandic Empire and Imperial Japan to be implemented.  Piepers warned against this ‘surrender’ to Japanese claims, arguing that the change emerged from a wide-spread misunderstanding of the legal and constitutional regulations with respect to legal entitlements in the Netherlands Indies. This article interprets Piepers’ passionate defense of the judicial status quo concerning equality founded on ‘legal’ definitions of difference, as an avant la lettre constitutional ‘apartheid’ argument. Piepers’ view on Netherlands Indies state formation started from a legal pluralism with subjectively defined groups. We will argue how in these subjectivities resonate three levels of power relations around 1900: a) geopolitical; b) national/state/colonial c) individual; with long-living aftermaths. Piepers final line of defending the status quo is the distinction between the just de jure equality in colonial society and the unjustified de facto hierarchical relationships between the different population groups. This very opposition between just laws and unfair practices in colonial governance obscures how the Eurocentrism of European (liberal) legal thought inevitably resulted in racist practice

Many women mainly in rural India are involved in SHG movement and are trying to improve their livelihood. This article attempts to understand women empowerment, its dimensions, the concept of self help groups and their role in women empowerment.
Resolving Conflicts in Data Through Curation-informed Weight Distribution Networks
Authors: Nevan Simone  , Maria Esteva
Published: November 2024

Missing and conflicting data values create problems when integrating datasets from multiple collections. Moreover, when the collections to be integrated are large and continuously updated, it is not feasible to manually resolve these problems. Instead, disagreements and gaps should be resolved in an automated fashion. To achieve good quality integrated datasets automatically we introduce the Curation-informed Weight Distribution Network (CiWDN), a method that suggests which collection is more reliable in providing a data value in question. CiWDN adapts the PageRank algorithm (PR) to assign and distribute weights across data fields present in the different collections. Weight assignment is rooted in data curation best practices as metrics of a collection's reliability. The metrics include: a) data completeness, b) data coincidence, and c) data consistency over time. Final weights used as collection ranks provide the basis to resolve conflicts between different collections contributing a data value for a given field. CiWDN relies on a data dictionary that normalizes fields across collections, and is implemented on a graph database. We demonstrate CiWDN’s capability using the case of ASTRIAGraph, a knowledge system built to increase transparency of activities in Earth’s orbital environment. CiWDN can assess the reliability of data collections that conflict on space object characteristic data fields, which can be used to resolve the differences. This method for computing collections' reliability can be ported to curate other types of large integrated datasets for use in machine learning and other data-driven applications.

Graphene: Study in Electronic Structure, Superconductivity and Potential in Quantum Information Sciences
Authors: Chapagain Aditya
Published: November 2024

Graphene, a two-dimensional lattice of carbon atoms, exhibits remarkable electronic properties due to its Dirac-like electronic excitations. This paper reviews the elementary electronic properties of graphene, including the tight-binding model for single-layer graphene and the band structure formation. The tight-binding Hamiltonian provides a fundamental understanding of graphene’s linear energy dispersion near the Dirac points, leading to unique phenomena such as massless Dirac fermions and chiral tunneling. We explore the potential of superconductivity in graphene using BCS theory. We find that BCS theory cannot explain superconductivity in graphene and its forms. This is in contradiction with the discovery of unconventional superconductivity in twisted bilayer graphene (TBG). The study further explores the potential application of bilayer graphene quantum in quantum information sciences, highlighting the development of states with relaxation times exceeding 500 ms. These valley states, arising from the hexagonal lattice structure, can be used to encode information as robust valley qubits for fault-tolerant quantum computing
Validation of the Brief Perceived Sexual Minority Discrimination Questionnaire-Community Version
Authors: Shadabi Saghar , Remedios Joshua , Gunnell Katie , Danyluck Chad
Published: November 2024

Sexual minorities—people who identify as lesbian, gay, bisexual, etc.—experience unique forms of discrimination. Yet few validated measures assess sexual minority discrimination, and none allow for comparison with other forms of discrimination. I examined an adaption of the Brief Perceived Ethnic Discrimination Questionnaire-Community Version (PEDQ-CVB) for use with sexual minorities (PSMDQ-CVB). Sexual minority participants complete the PSMDQ-CVB online in addition to measures of harassment, sexual minority identity, and well-being (N = 528). Exploratory factor analysis found that the PSMDQ-CVB's factor structure was inconsistent with the four-factor structure of the original PEDQ-CVB. The 16 items retained had strong internal consistency, and good convergent validity with measures of sexual minority discrimination. The PSMDQ-CVB had good divergent validity with measures of stressful life events, and sexual minority identity, and good predictive validity with well-being measures related to discrimination: symptoms of depression, anxiety, and physical ill-being. Results support the psychometric validity of the PSMDQ-CVB.
Personality, Parents, & Planning: Predicting Career Attitudinal Outcomes in Undergraduate Students
Authors: McCabe Sara , Campbell Bernadette
Published: November 2024

Personality, parental career-related behaviors, and career construction-based interventions have been shown to impact career adaptability. This study examined the influence of these factors on career concern, an understudied but important dimension of career adaptability, and career anxiety. Data from 297 students enrolled in introductory psychology courses were assessed using hierarchical regression analyses to explore the effects of personality factors (i.e., conscientiousness and neuroticism), parental career-related behaviors (i.e., support, interference, and non-engagement), and participation in a brief planning intervention on career concern and career anxiety. This study further explored the relationship between these career attitudinal outcomes and life satisfaction. Results indicated a significant role of personality factors and specific parental career-related behaviors in career concern and career anxiety. Career concern and conscientiousness also played significant predictive roles in life satisfaction. Our findings contribute to the career development literature and provide insights for both academics and career professionals.
Understanding Students’ Protective Behaviours Across Drinking Contexts
Authors: Lalsingh Gia , Howard Andrea
Published: November 2024

Protective behavioural strategies (PBS) for alcohol use are being widely studied to encourage safe and responsible drinking practices for student populations (Peterson et al., 2021), including harm reduction, limiting, and manner of drinking strategies. Contexts such as planned versus unplanned drinking days, as well as social and solitary drinking, may influence PBS use. The current study uses surveys (EMA) administered over 14 weeks between Thursdays and Sundays to test whether drinking contexts are related to students' use of different protective strategies. Linear regression analyses were used to assess whether the type of drinking day (planned vs. unplanned) interacts with social and solitary contexts to predict PBS use. Findings suggest that students drinking on planned days used more protective strategies across all three categories, with social drinking predicting greater PBS use across both unplanned and planned days. Future research should explore the efficacy of strategies with context-specificity to develop targeted interventions and policies to address the challenges associated with drinking among students.
Reflections on Limiting Social Media Use and Mental Health
Authors: Wilson Abby , Howard Andrea
Published: November 2024

The relationship between social media use and mental health has been well documented. A study by Bradley et al. (2023) examined whether reducing social media use to 30 minutes per day would improve mental health, but found no significant improvements, partly due to participants’ lack of adherence to study instructions. The current study examines qualitative responses to an open-ended reflection question from participants of this previous study. Most participants struggled to limit their social media use, largely because of benefits social media use provided and perceived consequences of not using social media. Many participants wanted to limit their social media use, despite most failing to do so during the study. Participants who did limit their social media use experienced improved mental health when limiting. Additionally, many participants had negative opinions about social media use, such as increasing social comparison, though positive and mixed opinions were also reported. This study suggests social media use limiting interventions may not be viable, and that different types of social media use must also be considered. Additionally, research viewing social media use as only having negative impacts is inaccurate; this study demonstrates that there is a continuum of effects it may have.
Examining the Effect of Interviewee Behaviour in Assessing Sexual Assault Victim Credibility
Authors: Mazzitelli Julianna , Luther Kirk
Published: November 2024

Sexual assault victims face doubts of their credibility when disclosing their experiences. Because of the traumatic nature of the assault, victims behave and express their emotions uniquely, which may impact their perceived credibility. The current study examined how a victim’s behaviour impacts their credibility during an investigative interview. Participants (N = 240) read one of six transcripts, depicting the investigative interview of a fictional sexual assault case. The victim (a male or female) displayed one of three behaviours (typical: crying; atypical: laughing; or neutral). After reading the interview transcript, participants assessed the victim’s credibility using the Witness Credibility Scale. Findings showed that women were perceived to be more credible than men, regardless of emotional expression (p = .032, BF10 = 1.385). There were no differences in the credibility of victims as a function of interviewee behaviors (p = .593, BF10= 0.071).
Did I Meet My Expectations? Exploring Whether Teen College Expectations Predict Degree Attainment and Mental Health
Authors: Campbell Lauren , McCabe Kira O.
Published: November 2024

The purpose of this study was to investigate the predictive power of teen college expectations on future degree attainment and mental health outcomes. It also explores the role of personality traits in this process. The data are from a sample of 8,984 U.S. residents who participated in the National Longitudinal Study of Youth – 1997 Cohort (NLSY97). Teens reported on their college expectations through self-reported measures in 1997 or 2001. In subsequent surveys (2008 onward), participants reported on their degree attainment, mental health, and personality traits. Individuals with high college expectations compared to individuals with low college expectations had a more positive personality trait profile and better mental health outcomes. When comparing people who met their expectations with people who did not meet their expectations, there were few differences in mental health. There were no significant interactions between college expectations and degree attainment, controlling for ability, socioeconomic status, and gender.
Advocacy and Allyship Matters: Well-being Among University Students With Disabilities
Authors: Young Kiera , Dupré Kathryne
Published: November 2024

It is important to understand factors that optimize the experiences of post-secondary students with disabilities. Although limited research has examined the factors related to their subjective well-being, some students with disabilities report lower well-being and greater loneliness than their counterparts. Thus, the purpose of this study was to examine the association between self-advocacy and subjective well-being, and whether self-compassion moderates this relationship, and the association between allyship and loneliness, and whether perceived organizational support moderates this relationship. In this study, 149 student participants, all of whom identified as having a disability, responded to an online questionnaire. While self-advocacy and self-compassion were both associated with well-being, self-compassion did not moderate the relationship. Similarly, while allyship and organizational support were associated with loneliness, organizational support did not moderate the relationship. This study contributes to the literature by identifying factors that may influence the well-being of students with disabilities within post-secondary environments.

Cardiovascular exercise is an empirically supported treatment for major depressive disorder (MDD); however, its effect on cognitive functioning is understudied. We examined how cardiovascular exercise influenced cognitive functioning in healthy youth and youth with MDD aged 16-24 (N = 51). We also assessed how twelve weeks of aerobic exercise intervention influenced cognitive functioning and depressive symptoms in youth with MDD. The Beck Depression Inventory (BDI) was used to measure depressive symptoms and the NIH Cognition Toolbox was used to calculate fluid and crystallized cognition composite scores. We expected increased cognitive functioning to correlate with larger decreases in MDD symptoms. We found no significant differences in baseline cognition scores between healthy and depressed youth. There were no significant differences between changes in VO2 max (an index of cardiovascular fitness) and depressive symptoms or cognition scores in depressed youth. We found a trend for an improvement in cognition scores after exercise intervention, suggesting that consistent cardiovascular exercise could enhance cognition. This study advances our understanding of aerobic exercise as a treatment modality for youth with MDD and the importance of alternative therapeutic interventions in depression.

Green beans are the most important food crop in Indonesia and production continues to increase to meet domestic demand. However, production is still insufficient due to several risks faced by farmers. This research analyzes the risk management of green bean production in Gluranploso Village using the Coefficient of Variation (KV) and Failure Mode and Effect Analysis (FMEA) methods. The results showed that yield variation was relatively low with a KV value of 17%, indicating good yield stability. The FMEA analysis identified four main sources of risk affecting production: seed aspect with an RPN value of 5.808, weather with an RPN value of 7.04, pests and diseases with an RPN value of 12.936, and technical aspects with an RPN value of 47.88, particularly delays in pest and disease control spraying. In addition, the market aspect is also a source of risk with the largest value in the increase in production input prices at 12.288. These sources require special attention in risk management. The study concludes that the implementation of appropriate risk management strategies, focusing on the identified key risk sources, can help farmers improve yield stability and farm profitability. These strategies include improving seed quality, mitigating weather risks, controlling pests and diseases, and improving technical procedures in cultivation and market risks. Thus, effective risk management can be key in increasing the productivity and sustainability of green bean farming in Gluranploso village.

Seaweed, being an abundant resource, has the potential to be processed into raw material for salt. This potential is supported by the high demand for salt consumption and the serious problem of hypertension in Indonesia. Consuming salt made from seaweed can be an alternative with low sodium content, which can help manage hypertension. Currently, the salt made from seaweed that is available to be purchased is Gamy salt. However, Gamy salt is more expensive than other low-sodium salts. This research aims to estimate the amount of consumers’ willingness to pay for Gamy salt and identify factors that influence their willingness to pay. The analytical methods used in this research include descriptive analysis, Contingent Valuation Method, and logistic regression. The research involved 103 respondents aged 30 years and above, residing in Jabodetabek, and having a history or risk of hypertension. The results indicate that the average willingness to pay for Gamy salt is Rp17,873.79 per 100 grams. Factors that significantly influence consumers to pay an extra price for Gamy salt are income, knowledge regarding seaweed salt, and health awareness.

Published: November 2024

O objetivo deste trabalho foi analisar as diferenças no perfil dos investidores em Fundos Imobiliários de Investimento (FIIs), que passaram a investir a partir de 2018, em relação ao dos que já o faziam antes. O início de 2018 marcou uma enorme expansão na base de investidores pessoas físicas em FIIs. Conforme a Brasil, Bolsa, Balcão (B3), houve um salto que foi de cerca de 121 mil investidores em dezembro de 2017, para mais de 1,17 milhões em dezembro de 2020 e a mais de 2,1 milhões em maio de 2023. Tal crescimento pode ser associado à significativa redução da taxa SELIC, de 13,75% a.a. em dezembro de 2016 para 2% a.a. em agosto de 2020, ou ainda à popularização do acesso via smartphones aos bancos e corretoras digitais, que não cobram taxas de corretagem em operações com FII. Para a execução do trabalho foi realizado um levantamento de dados com 134 investidores participantes de um fórum de discussão sobre FIIs. Os resultados apontam que há diferenças no perfil e padrões de tomada de decisões de investimentos, diante de múltiplas variáveis relacionadas ao mercado de FIIs, entre os grupos de investidores mais experientes e menos experientes, sendo o primeiro formado pelos respondentes que já atuavam no mercado de FIIs antes de 2018 e o segundo formado pelos que passaram a atuar após a grande expansão observado a partir daquele ano.
El texto escrito através del foro en clases de ELE en la EaD: potencial didáctico versus subutilización del género
Authors: Carvalho Tatiana Lourenço de
Published: November 2024

El trabajo describe cómo ocurren las clases de español como lengua extranjera (ELE) en entornos de Educación a Distancia (EaD), más especí­ficamente, respecto a las propuestas de actividades de los foros y referente al desarrollo de la enseñanza del texto escrito a través de ese género en una carrera de Letras em Lí­ngua Espanhola de la Universidade Aberta do Brasil (UAB). Metodológicamente, se trata de un estudio de caso con tratamiento cualitativo-descriptivo de los datos recogidos en la asignatura Lí­ngua Espanhola IV. Nos basamos teóricamente en Nunan (2002), Miller (2009), Bazerman (2006), Colombia (2011), Carvalho (2018) entre otros autores. El análisis reveló que la configuración de las propuestas de los foros observados no incentivó un proyecto de enseñanza de escrita integralmente participativo, o sea, que promoviera la interacción para un aprendizaje significativo de la lengua española dentro del entorno virtual de enseñanza y aprendizaje (EVEA).
As contribuições da Linguí­stica Textual nas diretrizes da Base Nacional Comum Curricular para o ensino de lí­ngua portuguesa
Authors: Brito Raí­ssa Martins , Carvalho Maria Angélica Freire de
Published: November 2024

Este artigo tem como objetivo apresentar alguns apontamentos da Linguí­stica Textual (LT) que contribuí­ram para a proposta da Base Nacional Comum Curricular (BNCC). Defende-se, neste texto, a perspectiva sociointerativa, que traz a linguagem como uma atividade social e a noção de texto como uma unidade em que o sentido é construí­do a partir da interação. Fundamentamo-nos em alguns estudos de Koch (2000, 2002, 2006), Marcuschi (1983, 2008), Bakhtin (2003 [1952-1953], 1997), entre outros, com o propósito de identificar as contribuições que a LT trouxe para a Educação Básica, mais especificamente, para o ensino de lí­ngua portuguesa. Metodologicamente, este artigo caracteriza-se como um estudo descritivo-interpretativo sob uma perspectiva analí­tica. Assevera-se, a partir da análise do documento, que o texto é visto como uma unidade de comunicação, como um ponto de convergência entre as dimensões de linguagem. É no texto que as relações gramaticais se constroem e se reconstroem e é no texto também que os discursos se concretizam. Verifica-se, portanto, uma preocupação da BNCC com o caráter dinâmico das práticas de linguagem, com as novas demandas sociais e com os contextos de usos de textos em uma perspectiva multissemiótica, que tem como suporte as novas mí­dias e os ambientes da Web.
