Etymology. The specific name refers to the type locality, Chu Yang Sin national park in Dak Lak province of Vietnam; it is to be treated as a noun in apposition. Distribution. Vietnam (High land provinces). Nest. A nest (Nest#VN-TN-2016-P-04) (Fig. 11) collected in Chu Yang Sin national park, Dak Lak province was examined. The nest had a comb comprised of several long cells, collected together with eight females. The nest was kept in a nylon bag in the car during travel, and two males emerged later when the nest was brought back to the laboratory (one male was broken when being taken out of the cell). The nest was found to be attached to a branch of Helicteres hirsute Lour. tree (Sterculiaceae) about 1.2 m above the ground. The nest characteristics are as follows: Petiole single, terminal, with thin central core of plant fibers, enlarged strictly with adult salivary secretion, dark brown and lustrous, 3.8 mm long, 0.8 x 1.3 mm thick; salivary coating extended onto substrate and largely onto back of comb. Comb tough, pliable in texture, light brown, subcircular (about 30 mm x 23 mm) in view from side of cell opening; ventral surface convex; dorsal surface concave. Nest cells generally arranged regularly and round at open end, but partly irregularly arranged (in some early short cells), where some cells are pentagonal; cell expanded towards open end, 2.7 mm (range 2.5–2.9 mm; n=5) wide at bottom and 5.6 mm (range 5.4–5.9 mm; n=6) wide at open end, 14.7 mm (range 14.0–16.2) mm; n=6) deep; cell wall about 0.2 mm thick. Cocoon caps yellow. Note on Polistes stigma subspecies: Two subspecies of Polistes stigma were recorded from Vietnam, namely Polistes stigma stigma (Fabricius) and Polistes stigma tamula (Fabricius) (Nguyen et al., 2017). For the latter, according to Castro & Dvorák, (2009), tamul- is an adjective, and as such must take the -us ending with a masculine genus like Polistes, so, the correct name, is Polistes stigma tamulus.Published as part of Nguyen, Lien T.

Privacy-Aware Data-Intensive Applications
No full textThe rise of Big Data is leading to an increasing demand for data-intensive applications (DIAs), which, in many cases, are expected to process massive amounts of sensitive data. In this context, ensuring data privacy becomes paramount. While the way we design and develop DIAs has radically changed over the last few years in order to deal with Big Data, there has been relatively little effort to make such design privacy-aware. As a result, enforcing privacy policies in large-scale data processing is currently an open research problem. This thesis proposal makes one step towards this investigation: after identifying the dataflow model as the reference computational model for largescale DIAs, (1) we propose a novel language for specifying privacy policies on dataflow applications along with (2) a dataflow rewriting mechanism to enforce such policies during DIA execution. Although a systematic evaluation still needs to be carried out, preliminary results are promising. We plan to implement our approach within a model-driven solution to ultimately simplify the design and development of privacy-aware DIAs, i.e. DIAs that ensure privacy policies at runtime

Distribution. Polistes meadeanus was recorded only from the Tay Nguyen plateau in the southern part of Vietnam (Nguyen 2014). The reported distribution of the species is confined to southern parts of Southeast Asia, or Sunderland and the southeastern part of Indochina. Its origin is possibly in Sunderland with subsequent northward dispersal to Vietnam, but Indochina origins and subsequent southward dispersal cannot be rejected.Published as part of Nguyen, Lien T.

The impacts of cancer treatment on lifestyle habits and mental health in Vietnamese women: an exploratory qualitative study
No full textAims: This qualitative study explores the experiences of women after cancer treatment in terms of habit changes and mental health impact. Method: The study involved 10 women who had undergone cancer treatment, recruited from three major hospitals in Hanoi, Vietnam. Data were collected through semi-structured interviews, which were transcribed and analyzed using thematic analysis. Results: The findings of the study shed light on the various factors influencing lifestyle behavior and mental health changes among women after cancer treatment. Ten participants, aged 39 to 64 years, shared experiences including dietary changes, sleep disruptions, and reliance on non-scientific sources for health decisions. Initially shocked by their diagnosis, many transitioned to acceptance, adopting a “giving-in” attitude. Cultural beliefs, word-of-mouth sharing, and social support networks played significant roles in shaping post-treatment lifestyle changes, coping mechanisms, information-seeking behaviors, and mental health. Conclusion: The study highlights the need for accessible and scientifically verified information for women after cancer treatment to make informed decisions about their health. It emphasizes the importance of addressing traditional beliefs and promoting evidence-based practices. Moreover, the study underscores the importance of social support and relationships in coping with the challenges of post-cancer experiences.No Full Tex
Valuing Transgenic Cotton Technologies Using a Risk/Return Framework
Get PDFStochastic Efficiency with Respect to a Function (SERF) is used to rank transgenic cotton technology groups and place an upper and lower bound on their value. Yield and production data from replicated plot experiments are used to build cumulative distribution functions of returns for nontransgenic, Roundup Ready, Bollgard, and stacked gene cotton cultivars. Analysis of Arkansas data indicated that the stacked gene and Roundup Ready technologies would be preferred by a large number of risk neutral and risk averse producers as long as the costs of the technology and seed are below the lower bounds calculated in this manuscript.cotton, financial risk, market value, SERF, transgenic, Agribusiness, Crop Production/Industries, Risk and Uncertainty, Q12, Q16,
The impact of frailty on prolonged hospitalization and mortality in elderly inpatients in Vietnam: a comparison between the frailty phenotype and the Reported Edmonton Frail Scale

The prevalence of frailty was 31.9% according to the REFS and 35.4% according to Fried’s criteria. The kappa coefficient was 0.57 (95% CI =0.49–0.66) between the two frailty criteria in identifying frail and non-frail participants. There was a trend toward increasing the likelihood of prolonged hospitalization in participants with frailty defined by Fried’s criteria (adjusted OR =1.49, 95% CI =0.94–2.35) or by REFS (adjusted OR =1.43, 95% CI =0.89–2.29). During 6 months of follow-up, 210 were lost and 18/251 (7.2%) participants died. Mortality was higher in those with frailty defined by either Fried’s criteria or REFS. On multivariable survival analysis, adjusted HRs for mortality were 2.65 (95% CI =1.02–6.89) for Fried’s criteria and 4.19 (95% CI =1.59–10.99) for REFS.Conclusion: Fried’s frailty phenotype or REFS can be used as a screening tool to detect frailty in older inpatients in Vietnam and predict mortality. Frailty screening can help prioritize targeted frailty-tailored treatments, such as nutrition, early mobility and medication review, for these vulnerable patients to improve clinical outcomes.
