Governing Masculinity: How Structures Shape the Lives and Health of Dislocated Men in Post-Doi Moi Vietnam

Since the start of Doi Moi (Renovation) over twenty years ago, Vietnam has increasingly opened its society and economy to the global capitalist economy and culture. The country has witnessed numerous changes in all aspect of everyday life, affecting individual men and women, their relationships with each other, and their relationships with other social and political institutions. My dissertation explores the challenges that three groups of dislocated men - men who were migrant laborers from a rural setting; men who were among the first methadone patients in the country; and men who sold sex to other men in Hanoi - were facing as they were struggling to build their manhood and to establish (or reject) aspects of culturally prescribed masculinities in post-Doi Moi Vietnam. I focus on their experiences with three structures, namely the market-bound socialist state, the fledgling capitalist market, and the patriarchal family, that together shape these men's everyday life struggles, their ethics of the self (especially their imagining of themselves as tru cot gia dinh, the pillar of the family), and ultimately their lives and health. I argue that in the context of post-Doi Moi Vietnam, these three powerful structures constitute, and are constituted by, the political economy of the male body, and that this relationship between structure and the body are best represented in the experiences of the men in this study. The male bodies examined here include: the exploitable body of migrant labors whose paths to manhood are limited by their lack of resources and capital other than their own sweat, tears, and flesh; the deviant body of men whose adherence to the regime of state-sponsored methadone is their only hope to recover from social death caused by their past heroin use; and the rejected body of men selling sex to other men who face the "problem of recognition." My analysis shows that their embodied forms of labor, whether on a highway, in a drug treatment center, or in a sexual marketplace, play a critical role in the making of their manhood. Their bodies are at the same time useful and disposable under the logics of power operated by the three powerful structures that offer possibilities, limitations, and various forms of desire (economic, erotic and ethical). While the male body of dislocated men bears great potential for man-making, they are also highly vulnerable to the exploitative practices of the state, to the vagaries of the market, and to disappointment of their own families. My dissertation shows various strategies, however seemingly premature, fragile and sometimes detrimental to their health, which these men deployed to overcome barriers and to make the best use of their limited resources in order to make their road to become tru cot gia dinh. These strategies, I will show, are forms of "strategic" and yet structurally determined decisions and action of these men, and they reflect constrained agency in confrontation with the "structural violence" that shapes experiences of dislocation, marginalization and stigmatization, and aggravates their vulnerability to HIV/AIDS. My dissertation contributes to social science theory of men and masculinities by bringing to the center of analysis the lived experiences of men in post-socialist settings that are often at the margin in studies on men and masculinities. My dissertation also contributes to the burgeoning literature on men and HIV/AIDS, and men's health in general, through deepened analysis of the political economy of the male body and the relationship of this political economy with vulnerabilities in relation to HIV/AIDS and other health issues

The Impact of TikTok UGC Videos on Online Purchase Intention: Mediating Role of Cognitive States

Background: User-Generated Content (UGC) videos have received considerable attention in recent years thanks to their great potential for buyers and sellers. However, the effect of this content on consumer behavior remains unclear, especially in the context of developing countries (e.g., Vietnam). By applying the Stimulus-Organism-Response model (S-O-R model), this paper examines the effect of UGC videos on online purchase intention. Moreover, the mediating role of cognitive responses, consisting of perceived credibility, perceived diagnosticity, and mental imagery, is also examined to offer valuable insights to businesses, enabling them to leverage and effectively promote the trends of UGC videos. Method: A convenience sampling method was employed to collect the data. A total of 318 valid respondents participated in this survey. The data was analyzed with the Partial Least Squares Structural Equation Modeling method (PLS-SEM). Results: The findings show that UGC videos have a direct impact on online purchase intention. This paper also verified that cognitive states mediate the relationship between stimuli and subsequent behavioral intentions. Conclusion: Our research findings enrich the literature on consumer’s online purchase intentions by applying the S-O-R framework by highlighting the role of cognitive responses, and improving generalizability by contributing additional consumer behavior findings in developing Asian nations. Moreover, this paper offers businesses insights into the formation of customers\u27 purchase intentions while watching UGC videos. Based on that, this paper raises practical recommendations regarding promoting the UGC video trend and creating UGC videos effectively to improve the cognitive states perceived by customers, including credibility, diagnostic value, and mental imagery

Active disturbance rejection control-based anti-coupling method for conical magnetic bearings

Conical-shape magnetic bearings are currently a potential candidate for various magnetic force-supported applications due to their unique geometric nature reducing the number of required active magnets. However, the bearing structure places control-engineering related problems in view of underactuated and coupling phenomena. The paper proposes an Adaptive Disturbance Rejection Control (ADRC) for solving the above-mentioned problem in the conical magnetic bearing. At first, virtual current controls are identified to decouple the electrical sub-system, then the active disturbance rejection control is employed to eliminate coupling effects owing to rotational motions. Comprehensive simulations are provided to illustrate the control ability

Structural barriers to HIV prevention among men who have sex with men (MSM) in Vietnam: Diversity, stigma, and healthcare access

Men who have sex with men (MSM) in Vietnam experience disproportionate rates of HIV infection. To advance understanding of how structural barriers may shape their engagement with HIV prevention services, we draw on 32 in-depth interviews and four focus groups (n = 31) conducted with MSM in Hanoi between October 2015- March 2016. Three primary factors emerged: (1) Diversity, both in relation to identity and income; Vietnamese MSM described themselves as segregated into Bóng kín (hidden, often heterosexually-identified MSM) and Bóng lộ (‘out,’ transgender, or effeminate MSM). Lower-income, ‘hidden’ MSM from rural areas were reluctant to access MSM-targeted services; (2) Stigma: MSM reported being stigmatized by the healthcare system, family, and other MSM; and (3) Healthcare access: this was limited due to economic barriers and lack of MSM-friendly services. Our research suggests the need for multiple strategies to reach diverse types of MSM as well as to address barriers in access to health services such as stigma and costs. While a great deal has been written about the diversity of MSM in relation to gender performance and sexual identities, our research points to the substantial structural-level barriers that must be addressed in order to achieve meaningful and effective HIV prevention for MSM worldwide

Investigation of anti-inflammatory lignans from the leaves of Symplocos sumuntia Buch-Ham ex D Don (Symplocaceae)

Purpose: To investigate the anti-inflammatory activity of Symplocos sumuntia Buch.-Ham. ex D. Don and identify the main secondary metabolites responsible for this effect.Methods: The in vitro anti-inflammatory activity of the plant extract and isolated compounds was determined in terms of the ability to inhibit the production of nitric oxide (NO), and expressions of iNOS and COX-2 proteins in RAW264.7 cells stimulated by lipopolysaccharide (LPS). Compounds were isolated and identified by spectroscopic methods.Results: The methanol extract of S. sumuntia leaves showed strong inhibitory effects on nitric oxide (NO) production and expression of iNOS and COX-2 in LPS-induced RAW264.7 cells. A phytochemical assay-guided fractionation of the methanol extract of S. sumuntia leaves led to the isolation of four lignans which are arctigenin (1), matairesinol (2), monomethylpinoresinol (3) and pinoresinol (4). These compounds were identified for the first time from S. sumuntia. All four compounds inhibited the production of nitric oxide (NO), with arctigenin showing the most potent activity with half-maximal inhibitory concentration (IC50) value of 4.08 μM.Conclusion: S. sumuntia is a promising source of anti-inflammatory agents, which may clarify to the therapeutic use of this plant in Vietamese traditional medicine.Keywords: Symplocos sumuntia, Symplocos caudata, Lignan, Arctigenin, Anti-inflammator

THE AMOUNT AND SPECIATION OF TRACE ELEMENTS TRANSPORTED FROM RICE FIELD TO CANAL DURING A FLOODING EVENT

Trace element pollution of soils, sediments and surface water can pose a risk for the local population and the environment of Vietnam. Rice fields can be affected by storm events, which cause the release of trace elements into surface water and transport them into drinking wells. The aim of this study was to investigate if dissolved and suspended As, Pb and Zn concentrations in surface water of a paddy rice fields and an irrigation canals increased during a flooding event and exceed the Vietnamese Surface Water Quality Standards and WHO Guidelines for Drinking-water Quality. The study site is a rice field area in the Thanh Hoa province in Central Vietnam, which experiences an average of 2.4 storms every year causing overflow of streams and low-order canals. Concentrations of As increased during the flooding event with dissolved As being the prevailing fraction, which followed a late flush behavior. Lead showed no significant difference in concentration over time. Zn concentrations only increased significantly in the canal upstream the field in the morning of the first day. Suspended Zn dominated at that time, following the first flush behavior of TSS concentrations. Concentrations of As, Pb and Zn did not exceed the Vietnamese Surface Water Quality Standards or WHO Guidelines for Drinking-water Quality at any time and they are therefore of no concern for the health of the local populatio

On a Sugar High: Role of O-GlcNAcylation in Cancer

Recent advances in the understanding of the molecular mechanisms underlying cancer progression have led to the development of novel therapeutic targeting strategies. Aberrant glycosylation patterns and their implication in cancer have gained increasing attention as potential targets due to the critical role of glycosylation in regulating tumor-specific pathways that contribute to cancer cell survival, proliferation, and progression. A special type of glycosylation that has been gaining momentum in cancer research is the modification of nuclear, cytoplasmic, and mitochondrial proteins, termed O-GlcNAcylation. This protein modification is catalyzed by an enzyme called O-GlcNAc transferase (OGT), which uses the final product of the Hexosamine Biosynthetic Pathway (HBP) to connect altered nutrient availability to changes in cellular signaling that contribute to multiple aspects of tumor progression. Both O-GlcNAc and its enzyme OGT are highly elevated in cancer and fulfill the crucial role in regulating many hallmarks of cancer. In this review, we present and discuss the latest findings elucidating the involvement of OGT and O-GlcNAc in cancer

Anatomical Characteristics and Variants of Prostatic Artery in Patients of Benign Hyperplasia Prostate by Digital Subtraction Angiography

AIM: This work is aimed to describe anatomical features and variants of the prostatic artery (PA) using digital subtraction angiography (DSA). METHODS: This is a descriptive statistic study. We reviewed the DSA of 348 patients, who had a PA embolisation to reduce the benign prostatic hyperplasia (BPH) symptoms at Radiology Department of Bach Mai Hospital from Oct – 2014 to Oct – 2018. RESULTS: PA was found at 660 pelvic halves, of which 30 pelvic halves (4.5%) had two PAs, 630 pelvic halves had one PA. In terms of the origin of PA, in total 690 PAs, the percentage of type 1, 2, 3, 4 and 5 was successively 33.9%, 13.9%, 18.3%, 23.9% and 10.4%, respectively. Atherosclerosis of PA observed in 20.9%. The ‘corkscrew’ pattern was found in 30.4%. The average diameter of PA was 1.5 ± 0.34mm. The anastomosis of PA with surrounding arteries was common. PA may supply rectum (6.1%), seminal vesical (9.6%), bladder (5.2%), contralateral prostatic parenchyma (13.0%), surrounding soft-tissues (3.5%). CONCLUSION: The common trunk with SVA superior vesical artery was the most common origin of PA. Anastomoses of PA with surrounding tissues were complex

Employment, Earnings and Social Protection for Female Workers in Vietnam’s Informal Sector

The informal sector plays an important role in employment creation and poverty reduction among female laborers in Vietnam. Currently, around 70 percent to 80 percent of women in Vietnam work in the informal sector, of which about 60 percent are in the agriculture and 20 percent are in the non-agricultural sectors that are mostly affiliated with small-size production and service units. By investigating the employment, earnings, and social protection policy on female labor in Vietnam’s informal sector, this research is able to answer the following research questions: 1) How important is the role of female labor in the informal sector? 2) What are the important factors that influence job opportunities for women in the informal sector? 3) What are the policy implications on female labor in Vietnam's informal sector? 4) What are the causes of work insecurities among females in Vietnam's informal sector? 5) What areas of social protection are most needed by women workers? 6) How does one address these principal needs for social protection among female workers
