    Models of residential space for ethnic minorities in Thanh Hoa Province associated with sustainable livelihoods

    Get PDF
    Thanh Hoa Province has 11 mountainous districts with seven ethnic minority groups, and the three largest ethnic groups are the Muong, Thai, and H'Mong. This region has great potential for developing a forest-based economy, ecotourism, community-based tourism, and cultural heritage tourism that is associated with cultural festivals, customs, lifestyles, and traditional housing architecture. However, developing a family-based economy, such as engaging in community-based tourism or agricultural production, has negatively affected and disrupted the structure of village spaces, spatial planning, and traditional house design. The arbitrary construction of additional service spaces and spaces for resident guests within the village space and the precinct of a house has reduced the area of the garden and agricultural land. The self-initiated modification, expansion, and use of non-traditional materials in traditional housing structures by residents to serve tourists have resulted in the loss of the architectural value of traditional homes. The exploitation of agricultural land has affected the natural forest area, the forest protection area at the headwaters, and the vegetation cover and natural ecosystems. Moreover, agricultural economic activities have not been linked to service activities, handicraft production, or tourism, and there are no adaptive residential space models, thus failing to create sustainable livelihood activities. Therefore, the article proposes settlement space models and orientations for residential space development including village spaces, house precincts, and traditional housing spaces of ethnic minorities in Thanh Hoa Province, associated with sustainable livelihoods based on the exploitation of traditional housing architectural heritage values to ensure local economic development. These models are closely linked with the conservation and promotion of ethnic cultural values, landscape preservation, environmental protection, and contribution to poverty reduction for residents

    Vietnam’s Accession to the World Trade Organization: Economic Projections to 2020

    This study presents a set of assessments of the long term economic effects of Vietnam’s accession to the WTO. Generally speaking, our results indicate that Vietnam would benefit from accelerating its participation in more open multilateralism. However, it is also clear from our analysis that these benefits will remain modest in the absence of comprehensive and complementary domestic economic reforms. Passive external liberalization, even when coupled with determined domestic reform, is inferior to WTO participation combined with negotiated market access and other activist multilateral agreements. Finally, our analysis shows that capital insufficiency is a very serious constraint on Vietnamese economic growth and diversification. Capital market reform can play an essential role in dynamic and sustained economic development for the country.Vietnam, WTO, Trade

    Thyroid carcinoma: correlation of the extent of disease at presentation and risk of death and recurrence with race/ethnicity and income differences

    BACKGROUND: Many research publications indicate that racial minorities and people in lower socioeconomic status are negatively affected by a higher morbidity and mortality rate in many diseases, including many cancers such as thyroid cancer. Although these disparities may be attributed to multiple factors, it is unclear whether a biological pre-disposition and/or the differences in levels of health care education, intervention and resources result in people of low-income levels and minorities presenting with higher risk and advanced stage of cancer. This commonly results in poorer prognoses, response to therapy, and outcomes. Even though thyroid cancer has had a progressive annual increase in incidence rates in the last thirty years across all demographic categories, the overall survival rate remains excellent. However, previous publications suggest that minorities and those in lower socioeconomic classes may present with higher-risk thyroid cancer cases. The goal of this research is to determine if socioeconomic status (SES) and race/ethnicity (R/E) influence the stage of the cancer and predict the risk of recurrence from thyroid cancer. To investigate, we performed an examination of our comprehensive THYROid CAncer REgistry (ThyroCARE) at Boston Medical Center, an urban tertiary care hospital with a diverse population, many of whom are from minority and international backgrounds, for the effect of SES and R/E on the initial staging and response to treatment. METHODS: A thyroid cancer registry was designed with the intent to capture both retrospective and prospective individual patient data at BMC. ThyroCARE resides in a browser-based Research Electronic Data Capture (REDCAP) program and contains 1,208 discrete data points related to initial and ongoing patient management. Patients were consented either in person or after receiving research documents through mail. Data is captured via individual record review and recorded in REDCAP. Analyses were performed with SPSS software. A total of 1305 BMC patients who have had treatment for thyroid cancer were consented and enrolled into the IRB approved BMC Thyroid Cancer Registry starting in 2010 with enrollment currently ongoing. Demographic, social history, and medical information were retrieved from the patients via IRB-approved surveys and a review of EPIC medical charts. An estimate of each patient’s median household income was determined by using their zip code and public data from the 2019 United States Census and American Community Survey that correlates income and zip codes. The information collected was then used to measure the initial and current risk of thyroid cancer, and the staging of the cancer across race/ethnicity and income level in the State of Massachusetts. RESULTS: Overall, there was no overall significant difference of thyroid cancer subtype with R/E but subset analysis show Black/African Americans have a lower prevalence of classic PTC and higher prevalence of follicular variant of PTC while Hispanics and Asians show the reverse with a higher proportion of classic PTC and lower proportion of FVPTC. When income level and R/E were compared, Black/African American and Hispanic/Latino patients had the greatest representation in the low-income bracket while Asian American and White/Caucasian patients had the greatest representation in the high-income bracket. However, there was no statistical difference seen when initial ATA risk of tumor recurrence and AJCC staging classification for risk of mortality were distributed across R/E or income level. A difference was seen in current ATA risk that reflects response to therapy as Asian American and Hispanic/Latino patients had a greater representation in the intermediate risk of recurrence category. Furthermore, low-income level patients had the least representation in the current ATA low risk recurrence group. CONCLUSION: In this safety net population of patients traditionally composed of patients who are non-Caucasians, have a low income and immigrant status, there was no statistical difference seen in the initial ATA risk and AJCC staging classification when distributed across levels of income or R/E. The initial presentation and extent of disease was not associated with R/E or income level. There is a difference in current ATA risk which reflects response to therapy. There was no significant difference in R/E in the ATA low or high current risk groups but, in contrast, the ATA intermediate risk demonstrated a higher prevalence of Asian and Latino/Hispanic patients. We hypothesize that this difference can be attributed to the higher percentage of Asian and Latino/Hispanic patients with classical papillary thyroid cancer, a tumor subtype with a higher potential for local invasion and lymph node metastases for these R/E groups. Future studies will examine if the difference in response to therapy is due to R/E or difference of tumor subtypes

    New H∞ control design for polytopic systems with mixed time-varying delays in state and input

    Full text link
    This paper concerns with the problem of state-feedback H∞ control design for a class of linear systems with polytopic uncertainties and mixed time-varying delays in state and input. Our approach can be described as follows. We first construct a state-feedback controller based on the idea of parameter-dependent controller design. By constructing a new parameter-dependent Lyapunov-Krasovskii functional (LKF), we then derive new delay-dependent conditions in terms of linear matrix inequalities ensuring the exponential stability of the corresponding closed-loop system with a H∞ disturbance attenuation level. The effectiveness and applicability of the obtained results are demonstrated by practical examples

    K.Marx-Engels and Ho Chi Minh Viewpoints on Journalism - and Two Fake News Publishing Cases of Thanhnien.vn and Tuoitre.vn (Online Magazines) in Vietnam and Lessons from Indonesia, Japan Approaches

    In this paper, by using qualitative analytical analysis with 2 case examples of Thanh nien and Tuoi tre newspapers (online) in Vietnam, in which there are history of publishing fakes news online from 2015, 2016, 2018, 2022 (with very bad editors Nguyen Ngoc Toan and Dang Thi Phuong Thao), as well as giaoduc.edu.vn and vietnamnet.vn in 2022 so we will address some points in this study based on answers for question: “What are regulatory lessons from Indonesia and Japan approaches on publishing fake news?”. We would suggest that there are penalties for negative behaviors of posting fake news online (any fake information) in the context of covid 19 epidemic. Tapsell (2019) defined ‘hoax news’ as similar to the more globally recognized term ‘fake news’: material deliberately fabricated and masqueraded as truth. At last, we will draw some lessons from K.Marx and Ho Chi Minh viewpoints on journalism for educating young generation in emerging markets such as Vietnam
