Taxonomy of usage problems for improving user-centric online health information provision

Consumer health information portals (HIP) are a popular means to provide quality health information via the Web. However complex usage problems in HIPs are still a major barrier to their success. A usage-driven approach, which places emphasis on improving online services based on learnings from the data of the interactions between users and the system, is crucial to ensuring sustainable and user-centred online health provision. Inspired by this idea, we present a taxonomy of usage problems that encompasses the dimensions of the content, the systems and users, focusing on a holistic understanding of usage problems. Our taxonomy is grounded on a literature analysis empirically validated through an analysis of usage-data captured from a consumer health information portal, operational for the past five years. By exploring how usage data highlights user problems, we also present strategies for health portal improvements based on better understandings of usage data. Benefits of usage-driven health portals in terms of smart learning capabilities to improve content and user satisfaction are discussed

However, the research has certain limitations: (i) Due to limited resources in conducting research, the sample size consisted of 305 tourist, (ii) This study conducted a sampling technique method of using direct interview methods from tourists in Ho Chi Minh city, Viet Nam, but the sample may not have been representative enough

Taxonomy of Usage Issues for Consumer-centric Online Health Information Provision

Consumers are increasingly using Internet portals when searching for relevant health information. Despite the broad range of health information portals (HIPs) available, usage problems with such portals are still widely recognized and reported. In this study, we analyzed usage data from an operational health information portal and identified ways in which these problems can be addressed. While previous usage data and log analysis research has focused more on user behaviors, query structures, and human-computer interaction issues, this study covers more comprehensive issues such as content. We describe a taxonomy of usage issues derived from a literature analysis. We describe how we validated and refined the taxonomy based on analyzing the usage data from an operational health portal. Findings from the usage data indicate that a range of content issues exist that lead to unsuccessful searches. The analysis also highlights that users’ ineffective information seeking strategies are not well supported by the system’s design. We use this taxonomy to propose a usage-driven, consumer-centered approach for dynamic improvements of HIPs. We also discuss the study’s limitations and directions for future research

Towards sustainable development : Coupling green marketing strategies and consumer perceptions in addressing greenwashing

To understand how consumers perceive greenwashing, this study examines the impact of green advertising receptivity (GAR), non-deception (ND), green brand image (GBI) and transparency (TR) on green brand trust (GBT) and subsequently the impact of GBT on consumers' purchasing intentions (PI). We also consider the mediation role of GBT between the relationship of the independent variables (GAR, ND, GBI and TR) and the dependent variable (PI). At the same time, we examine the moderating impact of ND on the GAR and GBT and of TR on the GBI and GBT relationship. Using the Stimulus–Organism–Response (SOR) framework, we test a number of hypotheses. A survey-based questionnaire was utilized to gather the data from Vietnamese respondents (n = 262). We analysed the data using the partial least squares (PLS) method, which is a structural equation modelling (SEM) technique, with the assistance of the SmartPLS computer program 3.0. The data results show that GAR and GBI positively influence GBT, but the influence of ND and TR on GBT is insignificant. Again, the data show that GBT has a positive influence on PI, and as a mediator variable, it facilitates GAR, GBI and PI, but not the link between ND, TR and PI. A significant interaction effect of ND demonstrates that it strengthens the GAR-GBT relationship. However, the TR has no impact on the GBI–GBT relationship. The findings of this study provide insights into the theory and the essential managerial implications for successfully managing the implementation of green marketing strategies.© 2023 The Authors.

Factors Effect on Tourist Loyalty: A Case Study of Homestay Tourism in Ben Tre (Southern Vietnam).

The purpose of this paper is to measure the effects of homestay service quality, tourist satisfaction, and cultural contact on tourist loyalty: a case of homestay tourism in Ben Tre (Southern Vietnam). This study has used qualitative and quantitative researches: (i) qualitative research was carried out through focus group discussions with 10 tourists, and (ii) quantitative research was conducted through direct interviews with 294 tourists in Ben Tre Province (Southern Vietnam). The results show that: (i) tourist loyalty is affected by 04 components of homestay service quality (reliability, responsiveness, assurance, and tangibles), tourist satisfaction; and (ii) tourist satisfaction is affected by 05 components of homestay service quality (reliability, responsiveness, assurance, tangibles, and empathy), and cultural contact. However, the research subject has certain limitations: (i) due to limited resources in conducting research, the sample size consisted of 294 tourists, (ii) This study conducted the sampling technique of using direct interview methods from respondents using homestay services in Ben Tre Province, Vietnam

How cheap can hygienic latrines be?

A construction and operation costing of 12 types of hygienic latrines widely used in rural areas of Vietnam and presented in the Hygienic latrine Manual of the Ministry of Health, using traditional construction materials has been conducted. The cost of latrines using traditional construction materials is ranging from USD37.5 (VIP) to USD194.4 (Septic tank constructed by brick for treatment of black and grey wastewater from sitting bowl toilet). Annually averted O&M costs of Vietnamese latrines range from USD1.86 (VIP) to USD 4.58 (wet latrine with septic tank) per capita per year. Costs of hygienic latrines can be further reduced, applying solutions such as using local materials for construction, reducing the tank volume by using the water-saving flushing devices or applying more frequent tank emptying services and mass production of latrine components. The less a hygienic latrine costs, the more chance for poor people in different places can get access to improved sanitation

Characterization of arsenic-resistant endophytic Priestia megaterium R2.5.2 isolated from ferns in an arsenic-contaminated multi-metal mine in Vietnam

Bioremediation is a biological process to remove or neutralize environmental pollutants. This study was carried out to investing at the efficacy of arsenic resistant endophytic bacteria isolated from Pteris vittata, Pityrogramma calomelanos, Blenchum orientale, and Nephrolepis exaltata, which grow in a highly arsenic (As) contamination mining site in Vietnam. Their segmented roots, stems, and leaves were homogenized separately and inoculated on LB agar plates containing 5mM As(III) and As(V). A total of 31 arsenic resistant endophytic strains were selected, in which strain R2.5.2 isolated from the root of P. calomelanos had the highest arsenic resistant capability. Strain R2.5.2 tolerated up to 320 mM and 160 mM of arsenate and arsenite, respectively. The strain developed well on a media of 0.1 5% NaCl, at 20-40ºC and pH 5 9, and actively utilized most of the sugar sources. It had a high IAA biosynthesis capacity with an average concentration of 19.14 mg/L, tolerated to 0.5-16 mM concentration of Ag+, Hg2+, Co2+, Ni2+, Cu2+, Cr4+, and reduced As(V). Based on 16s rDNA, R2.5.2 was identified as Priestia megaterium. The ars C gene coding for arsenate reductase catalyzing reduction of As(V) was successfully amplified in P. megaterium R2.5.2.  The selected strain may have potential use for bioremediation practice

Enhanced Private Sector Engagement for Tuberculosis Diagnosis and Reporting through an Intermediary Agency in Ho Chi Minh City, Viet Nam

Under-detection and -reporting in the private sector constitute a major barrier in Viet Nam’s fight to end tuberculosis (TB). Effective private-sector engagement requires innovative approaches. We established an intermediary agency that incentivized private providers in two districts of Ho Chi Minh City to refer persons with presumptive TB and share data of unreported TB treatment from July 2017 to March 2019. We subsidized chest x-ray screening and Xpert MTB/RIF testing, and supported test logistics, recording, and reporting. Among 393 participating private providers, 32.1% (126/393) referred at least one symptomatic person, and 3.6% (14/393) reported TB patients treated in their practice. In total, the study identified 1203 people with TB through private provider engagement. Of these, 7.6% (91/1203) were referred for treatment in government facilities. The referrals led to a post-intervention increase of +8.5% in All Forms TB notifications in the intervention districts. The remaining 92.4% (1112/1203) of identified people with TB elected private-sector treatment and were not notified to the NTP. Had this private TB treatment been included in official notifications, the increase in All Forms TB notifications would have been +68.3%. Our evaluation showed that an intermediary agency model can potentially engage private providers in Viet Nam to notify many people with TB who are not being captured by the current system. This could have a substantial impact on transparency into disease burden and contribute significantly to the progress towards ending TB

Spatial Organization and Molecular Correlation of Tumor-Infiltrating Lymphocytes Using Deep Learning on Pathology Images

Beyond sample curation and basic pathologic characterization, the digitized H&E-stained images of TCGA samples remain underutilized. To highlight this resource, we present mappings of tumorinfiltrating lymphocytes (TILs) based on H&E images from 13 TCGA tumor types. These TIL maps are derived through computational staining using a convolutional neural network trained to classify patches of images. Affinity propagation revealed local spatial structure in TIL patterns and correlation with overall survival. TIL map structural patterns were grouped using standard histopathological parameters. These patterns are enriched in particular T cell subpopulations derived from molecular measures. TIL densities and spatial structure were differentially enriched among tumor types, immune subtypes, and tumor molecular subtypes, implying that spatial infiltrate state could reflect particular tumor cell aberration states. Obtaining spatial lymphocytic patterns linked to the rich genomic characterization of TCGA samples demonstrates one use for the TCGA image archives with insights into the tumor-immune microenvironment

Pan-Cancer Analysis of lncRNA Regulation Supports Their Targeting of Cancer Genes in Each Tumor Context

Long noncoding RNAs (lncRNAs) are commonly dys-regulated in tumors, but only a handful are known toplay pathophysiological roles in cancer. We inferredlncRNAs that dysregulate cancer pathways, onco-genes, and tumor suppressors (cancer genes) bymodeling their effects on the activity of transcriptionfactors, RNA-binding proteins, and microRNAs in5,185 TCGA tumors and 1,019 ENCODE assays.Our predictions included hundreds of candidateonco- and tumor-suppressor lncRNAs (cancerlncRNAs) whose somatic alterations account for thedysregulation of dozens of cancer genes and path-ways in each of 14 tumor contexts. To demonstrateproof of concept, we showed that perturbations tar-geting OIP5-AS1 (an inferred tumor suppressor) andTUG1 and WT1-AS (inferred onco-lncRNAs) dysre-gulated cancer genes and altered proliferation ofbreast and gynecologic cancer cells. Our analysis in-dicates that, although most lncRNAs are dysregu-lated in a tumor-specific manner, some, includingOIP5-AS1, TUG1, NEAT1, MEG3, and TSIX, synergis-tically dysregulate cancer pathways in multiple tumorcontexts
