The Philosophy, Politics and Economics of Food
Authors: Gelhaus Laura , Huan Lucas , Smith Aaron , Venkatram Vivek
Published: January 2025

The undergraduate degree Philosophy, Politics and Economics (PPE) has attracted a stereotype of developing future political and financial elites with little regard to the subject material covered in the programme. This clashes with student expectations and university messaging on PPE, which, especially at the University of Warwick, highlight the importance of interdisciplinary perspectives for addressing complex global challenges. This introduction to this special section argues that it is imperative to centre students’ voices in defining PPE, and, to this end, showcases a co-creation process aimed at developing an interdisciplinary module. The resulting module on the PPE of food thereby speaks to how students understand their PPE: as a programme that breaks with interdisciplinary silos to answer complex questions relevant to the world we live in.

This research aims to determine the legal certainty of the role of insurance supervisory institutions and the form of legal protection for insurance customers after the formation of the Policy Guarantee Institution (LPP). This has become urgent, considering that recently there have been many cases of failure to pay insurance claims to customers. This research method is normative, with an approach to statutory regulations and a conceptual approach. The sources of legal materials used are primary, secondary and tertiary legal materials. The method for collecting legal materials is carried out through literature study with the analysis method using analytical descriptive and systematic interpretation. The research results found that legal certainty regarding the role of insurance supervisory institutions is inherent in the Financial Services Authority (OJK) with its juridical basis being Law Number 21 of 2011 concerning the Financial Services Authority and Law Number 40 of 2014 concerning Insurance. OJK plays a role in risk mitigation and legal protection. The form of legal protection is preventive (prevention) and repressive (control). The policy guarantor is the authority of the Deposit Insurance Corporation (LPS). However, it is known that the minimum and maximum nominal limits of the policy guarantee that will be guaranteed are not regulated, thus indicating that legal certainty as well as legal protection for insurance customers has not been realized as it should be.

This paper aims to discuss the implementation of investigations into cybercrime in Indonesia and the United Kingdom. The implementation of investigations is an important process to ensure that a crime including cybercrime can be handled effectively, the perpetrators can be prosecuted based on applicable legal provisions, and the rights of victims can be protected. The problem in this paper is focused on exploring the implementation of investigations into cybercrime in both countries considering that along with the advancement of the digital era, cybercrime has become an ongoing challenge for law enforcement. In order to approach this problem, a reference is used for comparative criminal law theory to compare legal provisions and understand foreign laws so that they can be used as considerations for national legal reform. Data were collected through a statutory approach and a comparative approach and analyzed qualitatively. This study concludes that there are differentiating factors in the implementation of investigations into cybercrime in Indonesia and the United Kingdom. The implementation of investigations into cybercrime in Indonesia is under the coordination of police investigators, while in the United Kingdom, investigations into cybercrime are divided into two, namely the police who handle cybercrime cases at the regional level and the National Crime Agency which handles cross-border and high-risk cybercrime cases.

Enhanced WSN security based on Trust-Based Secure Intelligent Opportunistic Routing Protocol in agriculture data transmission sector
Authors: Anulekshmi S
Published: January 2025

In recent years agriculture is a developing environment through remote sensing environment with support of Wireless Sensor Network (WSN). Increasing communication and Internet of things make a communication behind to share the information all over the monitoring fields However, due to the open nature of WSNs, they are vulnerable to various security attacks, which can lead to serious consequences, such as data integrity breaches, denial-of-service attacks, and identity theft. Machine Learning (ML) can be used to improve the security of WSNs to detect and prevent security attacks. ML algorithms analyze the normal behavior of WSNs and to detect anomalies that may indicate an attack. To propose a TBSIOP (Trust-Based Secure Intelligent Opportunistic Routing Protocol) for improving the security in WSN-agriculture environment. Initially the Weighted Trust Mechanism (WTM) is evaluated to find behaviors aspects of nodes in the communication medium. Then the data packets are secured through Elliptic Diffie-Hellman Encryption Integrated Cryptography (EDHEIC) on each handover to the communication nodes. In addition, the Substitutive Padding Key Verification (SPKV) is applied to securely handover the data by getting key authentication policy. Which prevents non-legitimate users from accessing the network. The security can be carried out by flooding the network with packets, by sending malicious code to the network, or by overloading the network's resources. Finally, the TBSIOP works on the principle of best candidate selection model to ensure the routing to improve the security.  The proposed system achieves high performance to ensure the security in the level of trust-based routing, node authentication, secure data handover with proof of knowledge to deliver the data. This improves the security as well in higher data transmission rate, low level packet drop ratio with redundant time complexity compared to the other system.

Authors: Singh Anuradha
Published: January 2025

This study presents an analytical investigation into the dynamics of blood flow through a tapered stenosed artery, focusing on the influence of arterial shape on fluid dynamics. The arterial medium is modeled as a power law fluid. Governing equations for laminar, incompressible, and non-Newtonian fluid flow subject to appropriate boundary conditions are solved. Perturbation mathematical method has used to get the analytical expressions. Equations are derived for key flow parameters, including velocity components, volumetric flow rate, wall shear stress, and pressure gradient. The findings reveal significant insights into the impact of arterial shape on fluid dynamics, highlighting how variations in artery geometry affect velocity profiles, pressure gradients, and wall shear stress distributions. Specifically, the study observes notable changes in wall shear stress with alterations in the tapering angle of artery. This research contributes to a deeper understanding of the complex interplay between arterial geometry and blood flow dynamics, with implications for diagnosis and treatment of vascular diseases.

Well-being is the assessment of individual experiences with pleasant feelings like happiness and life satisfaction. Combined training is recommended for older adults to decrease age-related psychological changes and functional limitations. This systematic review aimed to assess the effects of a combined exercise program on happiness and life satisfaction in physically active older adults. The electronic databases of Google Scholar, Web of Science, and PubMed were searched between 2000 and 2023 for available literature. The searched keywords were: older adults, training, exercises, happiness, and life satisfaction. After completing the investigation, 931 publications were found. Inclusion criteria comprised physically active participants aged 60 years and above, along with studies composed in English. Studies in which participants had obesity, diabetes, and other non-communicable diseases were excluded from investigation. The qualitative analysis involved eight studies. These studies ranged in publication date from 2008 to 2022. The participants in the studies were men and women aged from 60 to 79 years. The sample size was 1849 and ranged from 35 to 656 participants. Physical activity was a combination of aerobic training, strength training, stretching exercises, and balance exercises. The most used questionnaire was the Satisfaction with Life Scale (SWLS). The findings indicate that older adults of both genders who underwent combined training programs had higher levels of happiness and life satisfaction. Research has shown that leading an active lifestyle enhances older persons' happiness and satisfaction with life. These results support the importance of maintaining an active lifestyle to improve the mental and emotional well-being of older adults.

Quail is one type of poultry that gained popularity in Indonesia. It is proven by the fact that many people are interested in raising quail and the number of people eating quail products is increasing, both eggs and meat. The advantages of quails are that they are easy to care for, produce quickly and have a high immunity to disease. Quail rearing research aims to determine the ripitability value of the calculation of egg weight and quail egg index. The study was divided into several groups and then assigned to raise quail every day in turn. The first thing to do in quail rearing is to weigh the body weight of the quail every week and then recorded, then measure the length of the shank using a caliper and expressed in mm. Feeding was done every morning, afternoon, and evening in the first week with a total dose of 20 grams/day. Another factor that affects the size of the egg and thus the ripitability value is the feed. The feed consumption rate of quails is influenced by the energy level and palatability of feed in quails. The feed consumption rate of quails was 109.69-135.59 g/head/week. The average feed consumption of quails in the study ranged from 127.12-165.15 g/head/week. Based on calculations from the recapitulation of data obtained during quail rearing, it is known that the ripitability value of egg weight and quail egg index is included in the low category.
Transforaminal interbody debridement and fusion with antibiotic-impregnated bone graft to treat pyogenic discitis and vertebral osteomyelitis: a comparative study in Asian population
Authors: Chang Chao-Chien , Chang Hsiao-Kang , Lu Meng-Ling , Wegner Adam , Wu Re-Wen , Yin Tsung-Cheng
Published: January 2025

Study Design: A retrospective cohort study.Purpose: To evaluate whether using antibiotic-impregnated bone graft (AIBG) enhances infection control and shortens the postoperative course of pyogenic discitis and vertebral osteomyelitis (PDVO).Overview of Literature: Surgical treatment of PDVO is indicated for neurological deficit, instability, unknown pathogen, or poorly controlled infection. The posterior-only approach is effective but requires 4–6 weeks of antibiotic treatment postoperatively. We hypothesized that AIBG used in an all-posterior approach could enhance infection control and shorten the postoperative course of PDVO.Methods: Thirty patients with PDVO of the lumbar or thoracic spine treated with transforaminal interbody debridement and fusion (TIDF) with AIBG between March 2014 and May 2022 were reviewed (AIBG group). For comparative analysis, 28 PDVO patients who underwent TIDF without AIBG between January 2009 and June 2011 were enrolled (non-AIBG group). The minimum follow-up duration was 2 years. Clinical characteristics and surgical indications were comparable in the two groups. C-reactive protein (CRP) levels and the postoperative antibiotics course were compared between the two groups.Results: Surgical treatment for PDVO resulted in clinical improvement and adequate infection control. Despite the shorter postoperative intravenous antibiotic duration (mean: 19.0 days vs. 39.8 days), the AIBG group had significantly lower CRP levels at postoperative 4 and 6 weeks. The mean Visual Analog Scale pain scores improved from 7.3 preoperatively to 2.2 at 6 weeks postoperatively. The average angle correction at the last follow-up was 7.9°.Conclusions: TIDF with AIBG for PDVO can achieve local infection control with a faster reduction in CRP levels, leading to a shorter antibiotic duration.
About one type of oriental residential building in the city of Ani, the medieval capital of Armenia
Authors: Baeva O. V. , Kazaryan A. Yu.
Published: January 2025

The study of architectural planning structure of two houses discovered in Ani during archaeological work in recent decades was undertaken in order to clarify their typological characteristics, architectural features and their place in the history of housing construction in the East. Acquaintance with the publications of archaeologists, the field surveys of objects in Ani undertaken by the authors led to the identification of a complex of stable features in these buildings, which made it possible to identify a range of typological analogies in the 12th–13th palace architecture of Armenians, Georgians, Seljuks of Asia Minor: the palace of Paron in Ani, the palace in Geghuti, built by the Georgian king George III around 1156, the palaces of Kubadabad, built in the first half of the 13th century. In the early Middle Ages, this idea was the basis for urban estates of the 19th–10th centuries in the Semirechye region of the Central Asia, there were still Sogdians. In some forms, in the structure of a four- or two-column covered courtyard, most likely, the embodiment of the central cell of a traditional Armenian residential building was added to the general idea. Two variants of creating such a cell could be presented in the two studied houses of Ani: with four columns in the corners of the central square and a two-column type based on the columns supported of opposing wooden beams. The probable prototypes of the general compositional idea of these houses in the architecture of Parthia and Sasanian Iran have been identified.

Esta pesquisa teve por objetivo analisar os perfis dos estudantes protagonistas de ações do Programa Internacional Despertando Vocações no Instituto Federal de Pernambuco, Campus Vitória de Santo Antão, com a finalidade de elucidar a compreensão das mudanças organizacionais, permitindo visualizar de que forma os processos de habitualização, tipificação, objetificação e exteriorização se formam e influenciam no isomorfismo institucional. Para assim colaborar com o entendimento sobre formação empreendedora, protagonismo estudantil e mudanças organizacionais em instituições de ensino brasileiras através de uma exígua amostragem retirada dos programas PDVL (Programa Internacional Despertando Vocações para Licenciatura) e PDVAgro (Programa Internacional Despertando Vocações para Ciências Agrárias). Para a obtenção de dados foi aplicado um questionário com a finalidade de coletar uma amostragem dos participantes do PDVL e do PDVAgro. No total, o questionário obteve 32 respostas de participantes dos programas estudados, sendo 47% do PDVL e 53% do PDVAgro. Os resultados foram dispostos em Gráfico analisados. Com a análise dos dados obtidos foi possível constatar que a participação nos programas propiciou aos alunos o afloramento do protagonismo, bem como as características empreendedoras descritas por Dornelas (2008). Segundo frases e palavras citadas pelos pesquisados, é notório a contribuição dos programas no incentivo ao trabalho em grupo e o quão essas ações auxiliam no desenvolvimento pessoais e profissionais dos mesmos. Fator reforçado pela tendência dos respondentes em continuarem no programa durante todo período acadêmico. O IIDV (Instituto Internacional Despertando Vocações) – instituição responsável pelos programas – juntamente com o IFPE tem por princípios a democratização do ensino e o cooperativismo, e estes podem ser alavancados pelo desenvolvimento do Protagonismo e pela formação empreendedora, desenvolvida no âmbito do PDV.

A DIDÁTICA DA MATEMÁTICA E A ABORDAGEM INSTRUMENTAL: UM OLHAR PARA DISSERTAÇÕES E TESES DO BRASIL DE 2000 A 2020
Authors: Pachêco Franklin Fernando Ferreira
Published: January 2025

A Didática da Matemática se volta para as investigações relacionadas aos processos de ensino e de aprendizagem de conceitos matemáticos. No contexto francês, as inquietações que influenciavam os fenômenos de ensino e de aprendizagem da Matemática despertaram o interesse de pesquisadores da Didática da Matemática possibilitando o surgimento de distintos aportes teóricos: a Teoria das Situações Didáticas (Guy Brousseau), a Dialética Ferramenta-Objeto e jogos de quadros (Régine Douady), a Teoria dos registros de representação semiótica (Raymond Duval), a Teoria dos Campos Conceituais (Gérard Vergnaud), a Teoria Antropológica do Didático (Yves Chevallard), a Abordagem Instrumental (Pierre Rabardel), a Orquestração Instrumental (Luc Trouche), etc. Dentre desse conjunto, o foco investigativo desta pesquisa se concentra na Abordagem Instrumental de Pierre Rabardel. Propondo-se analisar o uso da Abordagem Instrumental enquanto aporte teórico em dissertações e teses realizadas entre 2000 a 2020 no Brasil. Buscou-se esses textos na Biblioteca Digital Brasileira de Teses e Dissertações, por meio de uma revisão sistemática, sendo selecionado os estudos que contemplassem no título uma das palavras-chave: Abordagem Instrumental, Gênese Instrumental, instrumentalização e instrumentação. Sendo, dessa forma, uma pesquisa do tipo qualitativa. Os resultados mostraram que no recorte temporal adotado de 2000 a 2020 apenas 10 textos (sendo cinco dissertações e cinco teses) versavam acerca das discussões sobre a Abordagem Instrumental no Brasil. Apesar disso, quantitativo baixo, verificou-se que as dissertações e as teses quando adotam as ideias de Rabardel (1995) exploram de maneira detalhada e aprofundada a importância de estudar as interligações entre os polos (sujeito-objeto-instrumento). Outro resultado revelado desses textos são a diversidade de participantes, área de conhecimento e artefatos com que pode ser trabalhada a Abordagem Instrumental.

Published: January 2025

O presente artigo apresenta a aplicação de um jogo de tabuleiro em turmas de Biologia do 3º ano do Ensino Médio durante as aulas remotas no Instituto Federal do Piauí - Campus Teresina Central. Dentro do contexto da pandemia do SARS-COV 2, muitas escolas adotaram o modelo de aulas virtuais, a partir disso, muitas complicações surgiram desde 2020 e uma delas é a forma de ensinar, em que, apesar de ferramentas tecnológicas serem utilizadas, a falta de contato e interações afetam a qualidade do ensino, por isso, faz-se necessário o uso de metodologias ativas que vão motivar os alunos e tornar a aprendizagem mais interessante e dinâmica. Em biologia, alguns conteúdos são transversais e atemporais, como é o caso da Evolução Biológica, estudada desde o Ensino Fundamental, até suas formas mais aprofundadas. A partir dessa necessidade foi criado o jogo de tabuleiro Bio Evolution com o objetivo de validar o uso de metodologias ativas e analisar a aprendizagem decorrente de sua execução nos conteúdos de Evolução. Para isso, foram elaborados três formulários, o primeiro contendo questões relativas ao perfil dos alunos e específicas de Evolução, que foi aplicado antes do jogo didático. O segundo questionário contendo questões de avaliação do jogo didático e da metodologia utilizada e também possui questões específicas do conteúdo de Evolução retiradas da Olimpíada Brasileira de Biologia (OBB). E finalmente, o terceiro formulário que foi um simulado, aplicado 5 dias após a aplicação do jogo, contendo cinco questões da OBB, para validação de aprendizagem. A partir da análise dos resultados foi verificado que os alunos demonstraram uma aprendizagem significativa dos principais conceitos de Evolução Biológica e se mostraram muito satisfeitos com a metodologia. Concluindo, apesar de algumas dificuldades acontecerem durante o processo de ensino-aprendizagem, as metodologias ativas são grandes incentivos à participação ativa dos alunos e contribuem para relações saudáveis de competição e cooperação.
Comparative Experiments for Generation of Banana Black Sigatoka Disease Stages as Labels for Multiclass Classification Tasks
Authors: Kambo Edwin , Nyambo Devotha , Leo Judith , Ally Mussa
Published: January 2025

Early and accurate diagnosis of Black Sigatoka (BSD), a fungal disease affecting banana production, is crucial for minimizing crop losses. An empirical understanding of the disease stages is important in developing predictors with adequate recommendations to farmers. This paper explores the use of K-means clustering algorithms to classify BSD stages in banana leaf images without relying on manual labelling. We evaluate the effectiveness of various image features, including “infected area”, “colour histograms”, “statistical features”, and “texture features”. The results indicate that using solely “infected area” achieved a moderate cluster separation, as observed from a Silhouette score of 0.5374 compared to others whose Silhouette scores were 0.3299 and 0.1366 for “statistical feature” and “colour histogram feature” respectively. Combining features, particularly, infected-area with texture or statistics, offered a promising balance between cluster separation and within-cluster variation as their Silhouette scores ranged between 0.32 and 0.47. Further investigation is needed to confirm the robustness of combining all features. This research lays the groundwork for developing automated BSD classification systems to aid farmers in early disease detection and improved crop management. Automated classification using machine learning algorithms can significantly reduce the time and effort required for disease monitoring. Additionally, the integration of multiple image features could enhance the accuracy and reliability of the classification system. Future work will focus on validating these findings with larger datasets and exploring advanced machine learning techniques to further improve classification performance. Ultimately, the implementation of such systems could lead to better-informed decision-making in banana cultivation, reducing the impact of BSD on global banana production.
Hemorrhagic astroblastoma: atypical presentation of a rare tumor. Illustrative case
Authors: Zumaeta Jorge , Martinez Raul , Santiago Rea Noe , Anicama-Lima William Efrain , Casavilca-Zambrano Sandro , Valerio Jose
Published: January 2025

BACKGROUND

Astroblastoma is an extremely rare tumor of the central nervous system, and its origin and validity as a different entity are still being debated. Because of its rarity and similarities to other glial neoplasms, it is often misdiagnosed, impacting treatment and outcomes.

OBSERVATIONS

Astroblastoma is very rare and mainly affects children and young adults. It does not have a definitive World Health Organization grade and is divided into low- and high-grade categories. The clinical presentation is consistent with signs of intracranial hypertension. Radiographic imaging shows a bubbly, solid-cystic supratentorial mass with irregular contrast enhancement. The case reported herein is unusual because the intratumoral hemorrhage caused compression and midline shift, requiring urgent surgery.

LESSONS

Astroblastoma with intratumoral hemorrhage is atypical and is associated with high-grade tumors. Managing severe intracranial hypertension requires emergency surgery to prevent fatalities. Treatment can include adjunctive chemotherapy and radiation therapy based on the extent of tumor resection.

Intentional staged embolization via the “highway bypass” using a radial artery graft for a large posterior circulation aneurysm: illustrative case
Authors: Indo Masahiro , Oya Soichi , Nakamura Sho , Kobayashi Ikuo , Yoshida Shinsuke , Shojima Masaaki , Nemoto Shigeru
Published: January 2025

BACKGROUND

The presence of significant tortuosity in access routes to aneurysms can interfere with catheter guidance and manipulation and significantly impact treatment strategies.

OBSERVATIONS

In this report, the authors combined intentional staged aneurysm embolization with the construction of a new direct access route, which they call a “highway bypass,” for a symptomatic posterior circulation cerebral aneurysm that was difficult to access with a catheter. Notably, the highway bypass is used for catheter passage, and technical tips should be considered. The patient had a symptomatic unruptured cerebral aneurysm in the first segment of the left posterior cerebral artery with bilateral internal carotid artery occlusion and severe tortuosity of the bilateral vertebral arteries. The highway bypass using a radial artery graft was performed in the first stage; in the second stage, the aneurysm was accessed using the graft, and embolization was performed. The catheter was passed through the graft without complications. The aneurysm was successfully embolized, no ischemic lesions were found in the postoperative images, and the patient was discharged without worsening neurological findings.

LESSONS

Intentional staged aneurysm embolization combined with the highway bypass effectively treats aneurysms that are difficult to access. Anastomoses should be designed to allow catheters to pass through the graft.

Published: January 2025

BACKGROUND

The co-occurrence of Rathke cleft cysts (RCCs) and meningiomas in the sellar and parasellar regions represents an exceedingly rare clinical entity. Achieving maximal resection through a single operative approach while minimizing adverse events is challenging, often necessitating multiple surgical approaches, as suggested by previous reports.

OBSERVATIONS

The authors report the case of a 49-year-old female with a history of kidney transplant who presented with headaches and was diagnosed with coexisting RCC and meningioma in the sellar and planum sphenoidale regions, respectively. Given the prolonged, refractory nature of her symptoms and based on her treatment preferences, a two-stage surgical approach was planned. This involved an endoscopic transnasal transsphenoidal approach followed by a right craniotomy to achieve maximal tumor resection while minimizing potential complications. No residual disease or tumor remnants were present at the 6-month follow-up. The pituitary gland was preserved, and the patient’s preoperative symptoms had fully resolved.

LESSONS

The preoperative diagnosis of concurrent skull base tumors is essential for effective management planning and determining the optimal surgical approach. The proximity of these tumors to critical neurovascular structures necessitates meticulous surgical planning to minimize adverse effects while ensuring maximal tumor resection.

Rathke cleft cyst with squamous metaplasia and activating mutations of mitogen-activated protein kinase signaling: illustrative case
Authors: Halaoui Adham , Estrella Melanie , Yan Carol H. , Goodwill Vanessa S. , Beaumont Thomas L.
Published: January 2025

BACKGROUND

Rathke cleft cysts (RCCs) are benign sellar/suprasellar lesions that result from mucin-secreting vestigial remnants within the pars intermedia of the pituitary gland. When symptomatic, they can present with retro-orbital headaches, visual field defects, and/or pituitary dysfunction.

OBSERVATIONS

A 35-year-old female presented with subacute retro-orbital headache, right ptosis, and blurred vision. Workup revealed panhypopituitarism with central hypothyroidism and adrenal insufficiency. Imaging demonstrated a sellar/suprasellar mass with subacute intralesional hemorrhage, which was thought to represent chronic pituitary apoplexy. The patient underwent an endoscopic endonasal approach in which the initial intraoperative frozen section suggested papillary craniopharyngioma. Subsequent specimens suggested RCC, thus presenting a surgical management conundrum. Hemihypophysectomy with lesionectomy was performed. Final histopathology demonstrated RCC with squamous metaplasia (RCC-SM), rupture, and hemorrhage. BRAF V600E was not detected. However, activating mutations in KRAS and MAP2K1 were identified.

LESSONS

RCC can undergo SM and rupture, leading to a hemorrhagic-appearing cystic sellar/suprasellar mass associated with cranial nerve palsies and hypopituitarism that mimics pituitary apoplexy. Intraoperative frozen sections can be ambiguous due to overlapping histopathological features with craniopharyngioma, complicating surgical decision-making. The authors hypothesize that RCC-SM may represent a transitional state between RCC and craniopharyngioma. Neurosurgeons should be mindful of this transitional entity and be prepared to modify their surgical strategy accordingly.

Published: January 2025

3-thiomethyl aniline-based azo dyes were prepared by conventional diazotization and followed by coupling reactions with various coupling components such as α-naphthol, β-naphthol, and 6-bromonaphthol under suitable experimental conditions. The isolated azo dyes are primarily confirmed by their orange-red color. Further via spectroscopic methods dyes are characterized and confirmed by various analytical techniques, such as IR, UV-visible, and NMR spectroscopic methods. Along with synthesis and characterization, computational studies and theoretical properties of the azo dyes are calculated and tabulated. DFT studies are also performed for the synthetic compounds. Optimized structures and electrostatic potential maps of azodyes are displayed and in addition, with the help of E-homo and Elumo various quantum chemical parameters relevant to nonlinear optical properties (NLO) properties are calculated and results are interpreted.

Authors: Ngo Thanh Son , Huu Duong Nong
Published: January 2025

This study evaluated the impact of pollution sources on the Ma River Basin in Son La Province, Vietnam, using data from local reports, statistical yearbooks, and scholarly literature. Through spatial analysis and statistical methods, the study mapped the distribution of pollutants across sub-basins in Song Ma district and assessed the pressure of each pollution source on water quality. The findings revealed that livestock raising and domestic activities were the major contributors to water pollution in the cluster 1 of sub-basins, while land-use activities were major threats to the surface water in the cluster 2 of sub-basins. The study recommended implementing centralized wastewater treatment systems in priority areas, promoting sustainable land management practices, and supporting environmentally friendly agricultural and livestock farming methods. These interventions are crucial for achieving sustainable development goals related to clean water and sanitation. The findings underscore the importance of integrated river basin management strategies to mitigate water pollution and ensure the long-term health and sustainability of the Ma River Basin.
Consumer Intention to Use Food Delivery Apps in Urban Cities: A Case Study of Hanoi, Vietnam
Authors: Minh Hai Ngo
Published: January 2025

Despite the rapid increase in online food purchasing practices, particularly through food delivery apps, within developing nations like Vietnam, there remains a dearth of research concerning consumer behavior in this domain. This study aimed to address this gap by investigating the factors influencing consumer intention to use food delivery apps (FDAs) in urban areas of Vietnam. Utilizing a consumer survey in Hanoi, a comprehensive analysis employing multiple linear regression and factor analysis was conducted. The findings indicated that individuals with previous experience using FDAs are more inclined to utilize these platforms for food purchases. Younger demographics exhibited a greater propensity for utilizing food apps for their food-related needs. Importantly, consumers with heightened awareness and trust in FDAs demonstrated a stronger intention to engage with these apps. Additionally, the study underscored the significance of user-friendly, visually appealing, and tailored food app designs in facilitating food purchases through these platforms. Furthermore, it highlighted the influence of food quality and marketing attributes on consumers' intentions to use FDAs. Based on these insights, recommendations were made for online food retailers to enhance market penetration via FDAs. These included designing visually appealing food apps, enhancing food quality, devising effective marketing strategies, providing comprehensive information about FDAs, and fostering consumer trust.
Internal Control System in Cooperatives: A Systematic Review
Authors: Vu Thi Hai , Tran Quang Trung , Bui Thi Mai Linh
Published: January 2025

Internal control plays an essential role in improving the efficiency of resources and ensuring the achievement of organizational goals. This study aimed to systematically synthesize articles published in Vietnam and abroad on the topic of “internal control” and “internal control system” in cooperatives during the period of 2012-2023. The conceptual framework of internal control, research methods, and main results of publications were summarized. The findings showed that empirical studies on internal control have frequently been conducted in financial and credit organizations, however, there are limited studies in the cooperative model. The publications focused on three main contents, namely the status and structure of internal control in organizations; the roles and impacts of internal control on performance and corporative governance; and the factors affecting the effectiveness and efficiency of internal control. The COSO framework has been applied by most authors in analyzing the current situation of internal control and internal control systems. The positive impacts of internal control on efficiency (ROA and ROE) and the sustainability of cooperatives were confirmed by the authors. Limitations in human resources, scale, technology, and staff awareness of internal control were considered as barriers to implementation of internal control in organizations.

The Saxophone, orientations and stylistic directions in French music of the 20th century “Lamento et Ronde” – Pierre Sancan
Authors: Constantin B. , Albu D.
Published: January 2025

For some, the tendency to think that the saxophone is an American instrument is very high, due to the fact that it is a true symbol of jazz. For others it is of Belgian origin, as its inventor was born in Dinant – Belgium. However, the saxophone originated and evolved in Paris. With a strong emotional impact, characterized by a tension of substance due to the tonal ambiguity suggested by the evolved chromaticism, “Lamento et Rondo” is the result of an advanced compositional thinking, which subjects the melody to a modulating variational work through thematic development procedures typical of the 20th century.
