Published: June 2024

The overseas expansion of Chinese brands and the presentation of their video advertisements has been a crucial topic in media studies. Researchers have found that more and more Chinese companies are expanding abroad in the context of economic globalization, yet there is still a research gap on the issue of advertising in overseas markets. Therefore, this paper aims to further analyses the similarities and differences in advertising presentation between two Chinese local cosmetic brands, Florasis and Perfect Diary with a particular focus on their advertisements on overseas online platforms. The comparative study reveals that there are significant differences in the brand images established by the two brands in overseas markets. The advertisement of Florasis has distinctive Chinese cultural characteristics and expresses the concept that "the national is the global", which reflects the unique cultural specificity in the international market. In contrast, Perfect Diary's advertising is integrated into the international market without Chinese traces, which shows its ambition to compete with other world-renowned brands.

Grammar Learning Methods and Grammar Learning Strategies: Are They Related?
Authors: Alzahrani Ibrahim Hanash
Published: June 2024

This study responds to numerous calls for research on Grammar Learning Strategies (GLS), an area that has been neglected for years. The research sheds light on the relationship between grammar learning or instructional approaches and students' utilization of GLS assigned to develop explicit and implicit knowledge of grammar. Two sub-categories of Pawlak's (2018) Grammar Learning Strategy Inventory (GLSI) were employed to assess GLS use in these two sub-categories by students who prefer explicit grammar learning and those who prefer implicit grammar learning. A Pearson correlation coefficient test was conducted to examine this relationship. The study revealed a moderate use of GLS for developing explicit and implicit grammar knowledge. Furthermore, it found an insignificant, fragile, and negative correlation between grammar learning or instructional approaches and GLS used to develop explicit knowledge of grammar. Similarly, an insignificant, very weak, and negative correlation was reported between grammar learning or instructional approaches, and GLS used to develop implicit knowledge of grammar. The study discusses factors influencing language learning and GLS use and highlights the limitations.

Published: June 2024

The current study investigates the openings and closings in the emails of Jordanian undergraduate students to their professors. It is significant as it provides invaluable insights into different aspects of student-professor interpersonal communication. This study seeks to fill a gap in the literature by examining how Jordanian university undergraduates open and close their first-contact emails to their professors. This study uses both quantitative and qualitative research methods. The sample of this study consisted of 200 authentic Arabic email messages drawn from a professor’s mail inbox. The data were analyzed based on Salazar-Campillo & Codina-Espurz’s typology of opening and closing. The findings reveal that the emails included all the opening and closing moves reported by previous research, however, with clear variation. The findings also show that openings and closings are used as politeness strategies to create a positive tone for student-professor academic interactions. Moreover, the study concludes that the emails resorted to more informal opening and closing formulas. The emails in this study do not conform to the norms and etiquette of student-professor email interaction. Furthermore, this study reports the use of emojis in almost all moves of the opening and closing sequences. Based on the findings, future studies are recommended.

Authors: Martins Grace , Mafimisebi Peter
Published: June 2024

Ayetoro, a coastal community in Ondo State, Nigeria is currently facing a saltwater intrusion that puts its survival at risk. This study analyzed (10) water samples from Ayetoro community's coastal aquifers to evaluate groundwater quality, saline intrusion impact, and conduct different physicochemical analysis. This paper discusses multiple causes of saltwater intrusion, such as the excessive use of freshwater and climate change, along with necessary methods for managing saltwater intrusion and the consequences it brings to coastal areas, the environment, and groundwater contamination in the region. The results were compared with the acceptable drinking water limits set by the World Health Organization (WHO). The findings showed that pH levels vary from 5.28 to 6.59, suggesting that the analyzed water samples may pose a threat to human health (such as skin irritation). The total hardness levels indicate that all water samples exceed the WHO's permissible limit of 500. High electrical conductivity values were observed in all water samples except for AY_9, indicating a likely presence of saline water intrusion in the groundwaters of Ayetoro community. Nonetheless, the levels of sulphate, chloride, sodium, potassium, total dissolved solids (TDS), and calcium-related hardness remained within acceptable limits for domestic use and irrigation in the entire study area, except for drinking water. Thus, it is advised to conduct consistent monitoring of saltwater intrusion to prevent contamination of other aquifers.

An tử dưới góc nhìn của Giáo hội Công Giáo
Authors: Nguyễn Ninh
Published: June 2024

Từ góc nhìn của Giáo hội Công giáo, vấn đề an tử không đơn thuần là quyết định cá nhân hay hành động từ bi nhằm giảm đau đớn. Mặc dù có những lập luận ủng hộ an tử dựa trên quyền tự quyết và lòng thương xót, Giáo hội Công giáo nhấn mạnh vào sự tôn trọng cuộc sống và lòng nhân từ không nằm ở việc kết thúc nó. Giáo hội khẳng định rằng giết chết không bao giờ là giải pháp đúng đắn, thay vào đó, cần tôn trọng và chăm sóc lẫn nhau đến cuối cùng, giảm bớt đau đớn và cải thiện chất lượng cuộc sống cho người bệnh. Điều này thể hiện lòng từ bi và tôn trọng giá trị cuộc sống, quan tâm đến tất cả các nhóm dân số, bao gồm cả những người trong hoàn cảnh khó khăn nhất. Theo lập luận của Giáo hội, sự sống là thánh thiêng và do Thiên Chúa ban tặng, vì vậy, không ai có quyền kết thúc cuộc sống của người khác, bất kể hoàn cảnh nào. Sự sống không chỉ giới hạn trên thế gian mà còn là sự sống vĩnh cửu trong Thiên Chúa. Giáo hội phản đối an tử vì vi phạm thiên luật và xúc phạm phẩm giá con người; quyền tự quyết cá nhân không thể vượt qua giá trị thánh thiêng của sự sống, và lòng thương xót không được biện minh cho hành vi giết người. Đau khổ và cái chết được xem là cánh cửa dẫn đến cuộc sống vĩnh cửu, giúp người Kitô hữu đối diện với chúng với bình an và hy vọng vào sự sống vĩnh hằng trong Chúa Giêsu Kitô.
Abstract
From the perspective of the Catholic Church, the issue of euthanasia is not merely a personal decision or an act of mercy to alleviate suffering. Although there are arguments supporting euthanasia based on individual autonomy and compassion, the Catholic Church emphasizes the sanctity of life and compassion that does not end with ending it. The Church asserts that killing is never the right solution; instead, it advocates for respecting and caring for one another until the end, alleviating pain, and improving the quality of life for the sick. This approach reflects a profound compassion and respect for the value of life, showing concern for all populations, including those in the most difficult circumstances. According to the Church's teaching, life is sacred and given by God; thus, no one has the right to end another's life, regardless of the circumstances. Life is not only limited to this world but also extends to eternal life in God. The Church opposes euthanasia as it violates divine law and offends human dignity; individual autonomy cannot override the sacred value of life, and compassion cannot justify the act of killing. Suffering and death are seen as gateways to eternal life, enabling Christians to face them with peace and hope in the eternal life through Jesus Christ.
Transgresiones familiares, transparentesco y vivencia del cuidado
Authors: Erazo Cortés María Isabel
Published: June 2024

Para las personas transfemeninas, la trayectoria vital suele estar anclada a realidades de exclusión y marginación; la necesidad de aunarse con otras mujeres trans en este caso es fundamental. El presente trabajo explora una de estas dimensiones: el cuidado asociado a la figura del transparentesco que trasciende lo meramente biológico, para constituirse en una posibilidad instrumental, simbólica y afectiva que les permite acompañarse y apoyarse. Se realizó una investigación de metodología cualitativa, con diseño hermenéutico, contando con la participación de nueve mujeres adultas con distintos roles dentro del transparentesco: madres, hijas, hermanas, usando metodologías de recolección de datos como la entrevista en profundidad y la observación participante. Los datos se analizaron mediante el sistema de codificación de datos propuesto por Strauss y Corbin (2002). El propósito del trabajo es dar cuenta de la manera en que se perciben las dimensiones relacional y comunitaria del cuidado en la experiencia del transparentesco construido y vivido por un colectivo de mujeres trans de la ciudad de Bogotá.
Crímenes contra población LGBTQIA+ en Guatemala : análisis interseccional del registro de denuncias del período 2019-2021
Authors: Tecu Ernestina
Published: June 2024

Los indicadores de violencia contra personas LGBTQIA+ aumentaron en los últimos años en Guatemala. El país no reconoce los crímenes por prejuicio como delito, limitando su condena y la reparación de las víctimas. El objetivo del trabajo es describir el comportamiento de los crímenes por prejuicio en Guatemala. Para esto, propongo una matriz de análisis interseccional para estudiar el comportamiento de los delitos según la identidad/orientación de las personas. La mayoría de los delitos ocurrieron en áreas metropolitanas, principalmente a migrantes, trans, gays y lesbianas. El estudio evidencia la intersección de género, orientación sexual y nacionalidad, y revela patrones como la feminización de la violencia sexual y la delimitación de espacios de muerte que pueden ser de gran utilidad para la formulación de políticas públicas enfocadas a la correcta y justa reparación de las víctimas.
Exploring Leadership approaches of Women in Climate Justice: Pathways to Impact and Empowerment
Authors: Ahmad Husna
Published: June 2024

This paper will examine the role of women in promoting peace through leadership in the climate justice space; through building an inclusive climate movement to tackle the triple planetary crisis facing the globe. Studies reflect that marginalised populations are disproportionately affected by climate change and environmental degradation, particularly indigenous communities and women, despite contributing the least to climate catastrophe. Women are among the 32.6 million climate migrants and refugees each year, who are in turn, at risk of experiencing gender-based violence. Standing at the frontlines of the triple planetary crisis, women are ideally placed to take up leadership roles within efforts toward achieving climate justice and a sustainable future. Women serve as primary caregivers, often responsible for providing food and water security, sustaining families and households in climate-affected regions. They are the first guardians and caretakers of our youth, possessing the necessary emotional depth, compassion, and maternal instinct to promote the values underpinning climate justice, which at its core, advocate for the sustenance of Mother Earth through an empathetic lens. Women, at the helm of community development and holistic wellbeing, are integral to building peaceful global communities through forming compassionate networks of changemakers, leaders and entrepreneurs adopting sustainable livelihood approaches. Following a conference on “Women, Religion and Climate Change, working together to move faster on climate change” which took place at Wilton Park in the UK in September 2023, an official report of findings and recommendations was produced, highlighting the real-life experiences, opportunities, and challenges within this arena. This report will serve as a key case study for this paper, drawing on discussions and focus groups among the diverse multi-lateral participants, influencers, and faith leaders present at this event. This paper will consider emerging approaches related to female leadership including the capability approach, the whole community approach, and the Islamic concept of Maslaha [Maslaha is an Arabic word, which means public interest]. These approaches also promote peaceful and sustainable societies and communities.

Customer Churn Analysis in Telecom Industry using Kaplan–Meier and Cox Proportional Hazards Model
Authors:   Department of Computer Science and Engineering, Oriental University, Indore, MP India, Sharma Ravi
Published: June 2024

Customer churn poses a significant challenge for companies in the telecom industry, impacting revenue and profitability. In this paper, we present a comprehensive survey of customer churn analysis methodologies, focusing on the application of logistic regression, Kaplan-Meier survival analysis, and the Cox Proportional Hazards Model. Logistic regression serves as a fundamental technique for binary classification, enabling the prediction of churn based on customer attributes and behaviors. Kaplan-Meier survival analysis offers insights into customer survival probabilities over time, facilitating the identification of high-risk cohorts. Additionally, the Cox Proportional Hazards Model provides a flexible framework for analyzing the impact of predictor variables on churn timing, accounting for censoring and time-varying covariates. Through a review of existing literature, case studies, and practical applications, we explore the strengths and limitations of these methodologies in customer churn prediction. We also discuss challenges in data collection, feature engineering, and model evaluation, along with future research directions to enhance churn analysis effectiveness. By leveraging logistic regression with Kaplan-Meier and the Cox model, telecom companies can develop robust churn prediction models to improve customer retention strategies and mitigate revenue loss. Keywords: Customer churn analysis, Telecom industry, Logistic regression, Kaplan-Meier survival analysis, Cox Proportional Hazards Model, Retention strategies.
Iraq's young agents of change: Supporting youth-led civic engagement after Tishreen
Authors: Al-Shakeri Hayder
Published: June 2024

Five years after the start of the Tishreen movement, the current absence of a mass protest movement in Iraq should not be interpreted as a sign that young people have become less ambitious, or that they more accepting of the status quo. There has been a strategic shift in many young Iraqis’ approach to activism and civic engagement since 2019, as a response to the high risks of more direct political confrontation. Drawing on a set of interviews with young people across Iraq, this paper presents case studies that explore the experiences of a new generation of political and civil society actors and entrepreneurs who are working to bring about constructive change within their communities. The case studies also illustrate the systemic challenges faced by young Iraqis in their efforts to challenge existing structures and norms, and drive incremental reform. Often over the last two decades, national and international policy responses and programmes, aimed at youth engagement and technical capacity-building, have overlooked the potential of young people to be proactive partners who can lead initiatives and influence systemic change. The paper offers a set of recommendations for how reform-minded officials within Iraq, along with international stakeholders, can help foster an environment in which young people can work together to bring about lasting change in Iraq. These emphasize refocusing capacity-building programmes to promote cross-sector collaboration; forging international partnerships to make more effective use of youth-focused initiatives and resources; building connections between youth activists and reformist officials; and guaranteeing the independence and accountability of forums such as the new Supreme Youth Council.
Outsourcing In India: Practical Approaches To Intellectual Property Issues From The Indian Company Perspective
Authors: Chesser Wilburn L , Cohen Steven A
Published: June 2024

International outsourcing transactions by their very nature require some understanding of the laws in multiple jurisdictions on a variety of subjects, including contract law and intellectual property rights law. Such an understanding becomes especially difficult if the systems of law are very different from each other, but it is required nonetheless to ensure that both parties are fully aware of the best ways to avoid liability and maximise their own benefits from the transactions. This article takes the familiar example of US companies outsourcing to India and discusses what the Indian company should be aware of in the context of the intellectual property issues involved, as well as the tactics it can use to maximise the market.
A Collective Rights Society For The Digital Age
Authors: Maloney John
Published: June 2024

Variations in digital copyright law in the international sphere have created unnecessary transaction costs to both consumers and producers who wish to transfer digital media efficiently. This article argues that the international community should create a collective rights organisation to bring uniformity, fairness, and efficiency to the process of transferring digital media and endeavours to construct the ideal model for such a collective rights organisation by describing a hypothetical collective rights organisation named PICRO (Possible International Collective Rights Organisation) and examining its operation using the example of digital music distribution. By illustrating the PICRO model in the light of current trends in international digital copyright law, the article aims to highlight the advantages of the proposed new system while underscoring the inherent weaknesses of having different digital copyright laws for different territories.

Zygomatic complex is the term used for Zygomatic bone, parts of maxilla, frontal bone, temporal bone and sphenoid bone. It forms the infrastructure of anterolateral part of the face and prominence of cheek.[1] Majority of zygomatic complex fracture occur due to road traffic accidents, other causes include fall, sports injury and assaults.[2] It transmits the occlusal stress to the base of skull along its vertical and horizontal struts. In majority of the cases of zygomatic complex fractures, the fractured part displaces inward. In cases of inwardly displaced zygomatic complex fractures trismus, epistaxis and diplopia are commom finding. [3] Subconjunctival haemorrhage is also one of the common features of the zygomatic complex fracture. Subconjunctival haemorrhage has no posterior limit and remains bright red owing to the ability of oxygen to diffuse through the conjunctiva to the collection of blood. This article presents a case series of management of malunited Zygomatic fractures at our centre.

This study aimed to measure the ball trajectory, club face control, and body movements of a long-drive distance golf player (LDP) who excels in international competitions. The participant randomly executed 10 shots of three trajectory types—straight, draw, and fade—using a driver in an indoor facility. The results indicated that the fade shot exhibited a significantly longer ball carry distance (S: 329.7 ± 31.7, D: 301.8 ± 30.6, F: 345.7 ± 18.4 yards). The offline distance also showed a significant increase (S: 3.6 ± 37.3, D: −12.0 ± 26.4, F: 30.8 ± 42.2 yards) for the fade shot. If shots exceeding the 60-yard width of the offline distance resulting in invalid attempts were counted, there were 2 of 10 attempts for straight, 0 of 10 attempts for draw, and 4 of 10 attempts for fade. Analysis of the ball trajectory of draw shots revealed a statistically significant trend towards lower peak height and descent angle. In all three trajectories, there were no significant differences observed in ball speed (S: 189.3±6.3, D: 192.1±5.0, F: 193.3±4.1 mph) and club head speed (S: 137.2 ± 1.6, D: 137.0 ± 1.2, F: 137.7 ± 2.2 mph). For the draw shots, the club path exhibited in-to-out trajectory, moving the club face, and the face angle was open during the ball impact. It is evident that even in golf players aiming for the maximum distance in a single shot, club head speed and grip speed tend to remain relatively constant. The findings indicate that the LDP executes precise movement and face control tailored to the three ball trajectories, demonstrating sophisticated motor control.

OBJECTIVE
To identify individual-level early warning indicators of virologic failure in HIV patients receiving antiretroviral therapy (ART) in South Africa.

DESIGN
A matched case–control
study of individuals with and without virologic failure (VF) (>5 months on ART and HIV-1 plasma viral load >1,000 copies/mL) was conducted between June 2014 and June 2018. Of the 1,000 participants enrolled in the parent cohort, 96 experienced VF, and 199 additional controls were identified
from the parent cohort and matched 1:2 (some matched 1:3) for sex, age, ART duration, and site. Participants were interviewed while clinical, pharmacy refill, laboratory, and objective pharmacological data were obtained. Multivariate conditional logistic regression models were constructed
using model selection to identify factors associated with VF. Significant determinants of VF were identified using an alpha level of 0.05.

RESULTS
In a full conditional model, higher cumulative ART adherence, quantified using tenofovir-diphosphate
concentrations in dried blood spots (OR 0.26) and medication possession ratio (OR 0.98) were protective against VF, whereas an increase in total depression score (OR 1.20) was predictive of VF.

CONCLUSION
This analysis demonstrates the
importance of depression as a key individual-level early warning indicator of VF. Efforts to address mental health concerns among patients with people living with HIV could improve virologic suppression.

Este trabalho possui natureza qualitativa, trazendo um relato de experiência compartilhada por docentes de saúde de cursos técnicos e superior de quatro instituições de ensino públicas e privadas, que ofertam cursos de nível técnico e superior de enfermagem e curso de medicina, localizadas no interior de Minas Gerais. O objetivo foi descrever os desafios de docentes de cursos técnicos e superiores em saúde no exercício da docência durante o período de pandemia. Para isso, foi realizada uma pergunta norteadora. Quais os desafios experienciados pelos docentes de cursos técnicos e superiores em saúde na educação remota no exercício da docência durante o período de pandemia? Assim, emergiram quatro categorias: 1) Desafios em relação aos recursos tecnológicos; 2) Desafios em relação ao processo da docência/práticas pedagógicas; 3) Mudanças de hábitos e rotinas na vida pessoal do docente durante o ensino remoto; 4) Consequências na esfera biopsicossocial durante o ensino remoto na pandemia. Para a análise dos dados utilizou-se da Análise de Conteúdo de Bardin. Os resultados revelam que a pandemia trouxe novos desafios ao processo de ensino-aprendizagem, resultando em mudanças de hábitos tanto físicos quanto emocionais. Emergiram abordagens inéditas, destacando-se o uso de tecnologias digitais, refletindo o esforço dos docentes em manter a qualidade do ensino mesmo diante das adversidades impostas pela pandemia.
Transformação espaço-temporal na cobertura e uso do solo no Cerrado goiano em populações de Caryocar villosum Pers. e Caryocar brasiliense Cambess. (CARYOCARACEAE)
Authors: Pereira Cláudio Sérgio Gomes , Peixoto Josana de Castro

O objetivo deste estudo foi avaliar a cobertura e o uso da terra, no espaço e no tempo, em quatro municípios goianos amostrados com duas espécies vicarintes: Caryocar villosum Pers. e Caryocar brasiliense Cambess, no período compreendido entre os anos de 2000 e 2020, verificando as consequências para a conservação da variabilidade genética de espécies vicariantes. O desmatamento das áreas de floresta em Nova Crixás e Aruanã podem ter causado diminuição da variabilidade genética das populações ali amostradas. A redução da floresta e da savana, para aumento da agropecuária, foram menores em Israelândia e Leopoldo de Bulhões. É perceptível a tendência de desvalorização das áreas savânicas em relação às florestais frente a agropecuária. A existência de pastagens degradadas pode indicar abandono do uso do solo pela dificuldade de produção. A urbanização e o crescimento dos municípios também alteraram o uso do solo. O aumento dos corpos hídricos no município de Leopoldo de Bulhões pode indicar represamento de mananciais.
