Consumers’ Trust in Sharing Economy Peer-To-Peer Platforms: A Case Study of Online Food Delivery in Hanoi, Vietnam
Authors: Anh Nguyen Thi Mai , Minh Nguyen Tuyet 
Published: April 2024

Purpose: The purpose of this study is to the influence of trust on consumers’ transactional intention within a P2P sharing platform focusing on consumers who used OFD in Hanoi, Vietnam.

Design/methodology/approach: A structured questionnaire is developed in a Google Form and distributed mainly through web-based and telephone-based platforms. In total, 240 valid responses were collected from Hanoi. To ensure the study's reliability and representativeness while minimizing bias, a convenience sampling method is employed, considering the demographic distribution of consumers across different age groups, genders, occupations, income levels, and various online food delivery platforms, income, frequency of consumption, and average expense. Analytical techniques included descriptive statistics, Cronbach’s Alpha reliability testing, and multiple regression analysis.

Results and discussions: Findings revealed that four of the seven factors examined exerted a significant positive impact on Consumers’ Intention to Transact: "Consumer’s Trust in supplying Peer’s Integrity”, "Consumer's Trust in Products Ability”, "Consumer’s Trust in supplying Peer’s Benevolence”, and "Consumer’s Trust in Platform’s Integrity”. Conversely, while “Consumer’s Trust in supplying Peer’s Ability”, “Consumer’s Trust in Platforms Ability”, and “Consumer’s Trust in Platform’s Benevolence” do influence ‘Customers’ Intention to Transact’, their effect lacks statistical significance.

Research Implications: This research sheds light on Vietnam's Sharing Economy, showcasing its transformative impact and governmental support. It focuses on the developing OFD sector, highlighting its rapid growth and significance. By adopting a trust-based research model, the study offers insights into consumer behavior within OFD platforms, contributing to the understanding of trust dynamics.

Originality/Value: The research provides a theoretical foundation for understanding trust's role in shaping consumer behavior and transactional intentions, laying the groundwork for empirical research and practical applications. Practically, the study offers actionable insights for policymakers and industry players. It emphasizes the importance of integrity, reliability, and effective communication in building consumer trust.

Published: April 2024

Background:
Congenital chloride diarrhea (CCD) is a rare autosomal recessive condition characterized by lifelong watery diarrhea. CCD is challenging to diagnose because of its severe clinical presentations and differentials. Therefore, it is crucial to be diagnosed early and receive appropriate management as it causes early death if left untreated or due to complications.

Case Report:
A Saudi newborn baby boy was passing a large amount of urine through the anal canal and was otherwise healthy. He was referred to our center with a high suspicion of a colovesical fistula. Diagnosed with CCD by the exclusion of fistula after confirmation with contrast study.

Conclusion:
This case highlights an unusual presentation of CCD mimicking a colovesical fistula. To the best of our knowledge, no similar case has been reported in the literature, and we believe this is the first Saudi case of CCD mimicking a colovesical fistula. It underscored the diagnostic challenges of this rare disorder and emphasized the importance of early recognition and accurate diagnosis to prevent such complications.

Published: April 2024

Pregnancy and delivery are physiological conditions that are marked by abrupt alterations to hormones, immunological and molecular characters. The current study aimed to evaluate oxytocin (OT), prolactin (PRL), cortisol and insulin growth factor-2 (IGF-2) levels as physiological biomarkers; programmed cell death protein-1 (PD-1), programmed cell death ligand-1 (PD-L1),interleukin-6 (IL-6) as immunological biomarkers, and single nucleotide polymorphisms (SNPs; rs53576 and rs2254298) of oxytocin receptor gene OXTR as molecular factors in samples of Iraqi women undergoing caesarean section (CS) and normal delivery (ND). Blood samples were collected from 96 pregnant women at term with ages ranging between 16-43 years. Regarding the physiological biomarkers, the study findings indicated that the change in OT, cortisol and IGF-2 between CS and ND groups was not significant, While the PRL level indicated a highly significant (P≤0.001) decrease in the CS group, especially in comparison with the ND group. Immunological biomarkers demonstrated a significant (P≤05) elevation for PD-1 as well as for PD-L1 in the CS group as compared to the ND group. However, PD-1/PD-L1 ratio revealed a high significant (P≤0.001) rise in CS compared with ND. The IL-6 results revealed a significant (P≤0.001) reduction in the CS groups compared to the ND group. And regarding the SNP of OXTR (rs53576), the findings revealed no notable association in genotypes CC, TC and TT between both groups. In addition, the mutant C allele and the wild T allele revealed no significant association between CS and ND groups [OR=1.26 (0.68-2.3%)]. The SNP results of OXTR (rs2254298) showed a high positive association (P≤0.001) in genotypes GG, AG and AA between CS and ND groups. Also, the mutant G allele and the wild A allele revealed high significance (P≤0.001) between both groups [OR=5.3 (2.8-9.76%)].

Effect of combining the shaping at magnet edge and dummy slotting at stator on the cogging torque reduction in permanent magnet generator was studied. The cogging torque is the most issues in permanent magnet generator application, since it effects to reduce the generator performance. A permanent magnet generator with 24 slots and 20 poles structure is presented. For purpose of study, in the beginning the permanent magnet generator with conventional structure has been investigated as the basic reference of initial structure. In order to improve the performance of the permanent magnet generator, the magnet edge was shaped but the stator core is kept remain conventional structure. It can be found that the magnet edge effects to inprove a little bit of the performance of the permanent magnet generator. In the next investigation, the magnet edge slotting and dummy slotting in stator core of the permanent magnet generator was combined. Using the FEMM 4.2, the cogging torque value of the proposed of permanent magnet generator were analysed and compared. It was found that cogging torque reduction of the permanent magnet generator with combining the dummy slotting at stator core and magnet edge shaping can reduce the cogging torque from 0.0028554 N.m (intial base line) to 0.0000165 N.m (proposed model). In other word, the cogging torque can be to around 99.42 % compared with the base line. The magnet flux density at core of the permanent magnet generator proposed can be reduced to 35 %.

Eigenvalue Interlacing of Bipartite Graphs and Construction of Expander Code using Vertex-split of a Bipartite Graph
Authors: Manickam Machasri , Desikan Kalyani 
Published: April 2024

The second largest eigenvalue of a graph is an important algebraic parameter which is related with the expansion, connectivity and randomness properties of a graph. Expanders are highly connected sparse graphs. In coding theory, Expander codes are Error Correcting codes made up of bipartite expander graphs. In this paper, first we prove the interlacing of the eigenvalues of the adjacency matrix of the bipartite graph with the eigenvalues of the bipartite quotient matrices of the corresponding graph matrices. Then we obtain bounds for the second largest and second smallest eigenvalues. Since the graph is bipartite, the results for Laplacian will also hold for Signless Laplacian matrix. We then introduce a new method called vertex-split of a bipartite graph to construct asymptotically good expander codes with expansion factor D/2 < alpha < D and epsilon < 1/2 and prove a condition for the vertex-split of a bipartite graph to be k-connected with respect to the second largest eigenvalue: Further, we prove that the vertex-split of G is a bipartite expander. Finally, we construct an asymptotically good expander code whose factor graph is a graph obtained by the vertex-split of a bipartite graph.

This article focuses on the implementation of the WCAG (Web Content Accessibility Guidelines) 2.1 guidelines into e-learning courses. The Quizer e-learning platform, which enables the creation of interactive multimedia courses, hasnprovided the basis for the introduction of the WCAG component. The platform includes two basic tools: an exercise creator and an exercise presenter. Once the Quizer Platform Exercise Wizard was analysed, a component was conceptualised and implemented to create e-learning courses compliant with WCAG guidelines and dedicated to people with disabilities. The technology for the implementation of this component was also presented. The function and validity of navigation through the courses using the keyboard and the use of screen readers were discussed as well. The research on the correctness of the WCAG standard implementation into e-learning courses was conducted with the use of designed cyber security quizzes. The final results of quizzes prepared according to WCAG guidelines and without WCAG were also compared. The research involved students majoring in computer science at Lublin University of Technology. Its results indicate the validity of using the WCAG guidelines in the design of educational content for students with disabilities and equalizing their educational opportunities.

Dalam bisnis khususnya pergerakan UMKM dan kebiasaan membeli masyarakat banyak dilakukan dalam platform digital. Grup whatsapp menjadi salah satu yang cukup mudah untuk membangun komunitas bertemunya penjual dan pembeli. Cara ini cukup membantu tapi memiliki banyak keterbatasan. Beberapa keterbatasan pangsa pasar kurangnya strategi pemasaran modern dan kurangnya kesadaran kolaborasi menyulitkan komunitas UMKM untuk mencapai target pelanggan yang lebih luas. Oleh karena itu, pendekatan sistem marketplace berbasis kolaborasi perlu diperkenalkan yang diharapkan dapat mendukung peningkatan eksistensi komunitas UMKM. Berdasarkan pelaksanaan pengabdian masyarakat ini, dapat disimpulkan bahwa terjadi peningkatan kesadaran berkolaborasi dari UMKM setelah mengetahui aplikasi e-Marketplace berbasis kolaborasi dan mendapatkan penyuluhan tentang pentingnya kolaborasi bagi sebuah komunitas, dibuktikan dengan peningkatan nilai post test dibanding pre test setelah dilaksanakan program pengabdian masyarakat.
Exploring the Landscape of Canadian Climate Policy
Authors: Winter Jennifer 
Published: April 2024

La politique canadienne en matière de climat est de plus en plus complexe, avec de nombreuses politiques obligatoires et volontaires visant à réduire les émissions de gaz à effet de serre. Ces politiques d’échelle nationale et infranationale comportent une variété d'instruments de politiques. Les interventions politiques peuvent viser l'ensemble de l’économie (p. ex., prix des émissions) ou certains secteurs seulement (p. ex., réglementation visant la production d’électricité propre), ou même des mesures précises (p. ex., des subventions pour le remplacement de combustible). Dans cet espace de politiques actives, il est crucial d’étudier les effets des changements et des interactions de politiques. L'article fait le survol des politiques climatiques canadiennes et décrit les tendances en matière de recherche dans le domaine des politiques climatiques et environnementales. En dépit de la richesse du paysage politique, il y a peu de travaux de recherche évaluant l'efficacité (réduction des émissions) et la rentabilité (coût par tonne de réduction de la pollution) des politiques climatiques canadiennes, de l’équité et des conséquences sur la répartition des choix en matière de politiques et de l'interaction entre les politiques. Des travaux de recherche supplémentaires sur ces thèmes pourraient aider à améliorer la conception des politiques et aider le Canada à atteindre ses objectifs en matière de réduction des émissions.Note des rédacteurs : Le premier volume de Canadian Public Policy/Analyse de politiques a été publié en 1975. Ce volume-ci est le cinquantième. Pour commémorer cet événement, nous avons organisé une série de conférences qui sont publiées dans ce numéro spécial. La professeure Winter a donné cette conférence lors des réunions de l'Association canadienne d’économique à Winnipeg en juin 2023.
