Bridging help-seeking options to Vietnamese Americans with parent–child conflict and depressive symptoms

To help practitioners bridge services to their clients who face family problems, this research aims to identify help-seeking behaviors among Vietnamese Americans who have experienced parent–child conflict and depression. The 2008 Asian Survey found that 46.3% of 572 Vietnamese Americans experienced parent–child conflict and 30.2% reported depressive symptoms. Having parent–child conflicts or depressive symptoms did not predict help-seeking from mental health professionals. Logistic regression results show that having parent–child conflict would increase the likelihood by 81.7% of a thinking that the problem will be naturally resolved; having depressive symptoms would increase the likelihood of seeking help from herbalists by 1.718 times and from medical doctors by 39.7%. Service strategies should include offering educational programs by multidisciplinary professionals with a focus on the natural aspect of building parent–child bonding.     

A primal-dual approximation algorithm for the Asymmetric Prize-Collecting TSP

We present a primal-dual ?log(n)?-approximation algorithm for the version of the asymmetric prize collecting traveling salesman problem, where the objective is to find a directed tour that visits a subset of vertices such that the length of the tour plus the sum of penalties associated with vertices not in the tour is as small as possible. The previous algorithm for the problem (V.H. Nguyen and T.T Nguyen in Int. J. Math. Oper. Res. 4(3):294–301, 2012) which is not combinatorial, is based on the Held-Karp relaxation and heuristic methods such as the Frieze et al.’s heuristic (Frieze et al. in Networks 12:23–39, 1982) or the recent Asadpour et al.’s heuristic for the ATSP (Asadpour et al. in 21st ACM-SIAM symposium on discrete algorithms, 2010). Depending on which of the two heuristics is used, it gives respectively 1+?log(n)? and $3+ 8\frac{\log(n)}{\log(\log(n))}$ as an approximation ratio. Our algorithm achieves an approximation ratio of ?log(n)? which is weaker than $3+ 8\frac{\log(n)}{\log(\log(n))}$ but represents the first combinatorial approximation algorithm for the Asymmetric Prize-Collecting TSP.     

Reduction in Dietary Acrylamide Exposure—Impact of Potatoes with Low Acrylamide Potential

Acrylamide forms primarily from a reaction between reducing sugars (e.g., glucose and fructose) and an amino acid (asparagine, Asn) formed naturally in foods, including potatoes. This reaction occurs when carbohydrate‐rich foods are heated at temperatures above 120 °C. Multiple potato varieties were transformed with potato genomic DNA that results in down‐regulation of the expression of the asparagine synthetase‐1 gene (Asn1), significantly reducing synthesis of free Asn, and consequently lowering the potential to form acrylamide during cooking. These potatoes with low acrylamide potential (LAP) were tested in agronomic trials, and processed into French fries and potato chips. Decreased levels of acrylamide were measured in these cooked food products when derived from LAP potatoes compared with those derived from conventional potatoes. These reductions can be directly attributed to reduction in Asn levels in the LAP potatoes. The corresponding average reduction in exposure to acrylamide from French fry and potato chip consumption is estimated to be 65%, which would amount to approximately a 25% reduction in overall dietary exposure. Considering that children consume nearly three times more acrylamide than adults on a per kg body weight basis, they would experience the most impact from the reduced acrylamide associated with LAP potatoes. The potential public health impacts, in context of dietary acrylamide exposure reduction, are discussed in this study.     

Working Adults and Personal Business Ethics in South East Asia: a Comparative Study in Thailand and Vietnam

Global leaders and managers have been facing new challenges in the twenty-first century since globalization has created a much more integrated and borderless business environment. One of the key issues that they constantly deal with is business ethics. The global economy has made ethical issues become more complex and challenging. Businesses nowadays face urgent demands to act ethically and responsibly. In order for global leaders and managers to manage such a cultural diverse and complex workforce, they must have the ability to understand these complex issues and act ethically. They also need to possess adequate leadership skills to lead an ethical organization in a multinational environment. Thus, understanding and recognizing the cultural differences as well as the ethical standards of people in different countries are critical to the success of global leaders and managers. The purpose of this study is to investigate the perception of working professionals on business ethics in the two high-context cultures in South East Asia: Thailand and Vietnam. Using the Univariate Analysis of Variance method and adopting the widely-used Clark and Clark’s Personal Business Ethics Scores (PBES) measure, this study will compare the level of ethical maturity of the respondents based on a variety of variables including gender, business law course taken, code of conduct, ethics training, and government work experience. The authors will provide a thorough literature review on business ethics as well as the current ethical issues, i.e., bribery and corruption, in the two countries, together with practical suggestions and implications for educators, managers, and employees.     

Social Relays of China’s Power Projection? Overseas Chinese Collective Actions for Security in France

Once known as a silent and even a model minority, hardworking and keeping a low profile, the Chinese community in Paris, one of the largest Chinese diasporic population in Europe, has organized several massive demonstrations since 2010 to demand police protection amid mounting security concerns. Based on qualitative methods combining ethnographic research, media analysis, observation of the collective actions, and interviews of key actors involved, this article analyses the evolution of these mobilizations and their aftermath, on a span of eight years from June 2010 to July 2018, aiming to comprehend the role of China’s influence diplomacy in regard to the actions of overseas Chinese for security. There hasn’t been any study on the role that overseas Chinese might play in China’s foreign policy towards Europe.     

Institutions matter: The case of Vietnam

The paper investigates institutional reforms in Vietnam and their impact on the economic performance of firms. Using the provincial competitiveness index 2006 (PCI06) and firm-level data in Vietnam in 2005, the results show that provincial competitiveness is economically and statistically significant in explaining cross-province differences in firm performance. We find that a 1% point improvement in government practice could increase the daily value-added of an average firm by an amount equivalent to nearly three times per capita GDP per day. The results show that an improvement in providing market information, more secure land tenure and labor training assistance has a positive effect on firm performance. By contrast, weaknesses in the judiciary system and administrative reforms impede growth of non-state firms. The findings indicate that governance is an important obstacle to the development of the non-state sector in Vietnam.     

On multivariate variable-kernel density estimates for time series

Let X₁ be a strictly stationary multiple time series with values in R^d and with a common density f. Let X₁,.,.,X_n, be n consecutive observations of X₁. Let k = k_n, be a sequence of positive integers, and let H_ni be the distance from X_i to its kth nearest neighbour among X_j, j i. The multivariate variable-kernel estimate f_n, of f is defined by where K is a given density. The complete convergence of f_n, to f on compact sets is established for time series satisfying a dependence condition (referred to as the strong mixing condition in the locally transitive sense) weaker than the strong mixing condition. Appropriate choices of k are explicitly given. The results apply to autoregressive processes and bilinear time-series models.     

Stress,Task, and Relationship Orientations of Vietnamese Working Adults: Do Age,Gender, and Government Work Experience Make a Difference?

Adult people are always structured diversely based on their gender, age, and work experience in the government versus private enterprises. To investigate the task, relationship and stress orientations of Vietnamese adults, this research examined 294 Vietnamese people living in three main cities in Vietnam including Hanoi (the capital) in the north, Vinh in the middle and Ho Chi Minh in the south. It found that they have different mean scores on task and relationship orientations. Gender, age and government work experience seem to be essential factors in leadership orientation and overload stress perception. Additionally, older people appear to be more task-oriented than their younger counterparts. In summary, the Vietnamese respondents confirmed a moderate stress perception regardless of age, gender and government work experience.

     

Structural Validation and Multiple Group Assessment of the Short Internalized Homonegativity Scale in Homosexual and Bisexual Men in 38 European Countries: Results From the European MSM Internet Survey

Internalized homonegativity (IH) is the internalization of negative attitudes and assumptions about homosexual people by homosexual people themselves. To measure IH, Smolenski, Diamond, Ross, and Rosser (2010) and Ross, Rosser, and Smolenski (2010) revised the Reactions to Homosexuality Scale (RHS) to develop the Short Internalized Homonegativity Scale (SIHS) with eight items. Using the European Men Who Have Sex With Men Internet Survey (EMIS) data, with an analytic sample of 130,718 gay and bisexual men in 38 European countries, we confirmed the validity of the SIHS scale in both training and validation data, in strata of Ross, Berg, et al.’s (2013) three “homosexual discrimination” country clusters, of age, and of education level. However, the performance was less adequate in comparison of gay versus bisexually identified individuals. The latent SIHS structure contains only minor variations across these three strata. The seven-item scale performed as well as the eight-item scale. The SIHS is a promising candidate for standard IH measures, which is invariant across cultural, age, and educational strata.
