One Mandarin Benefits the Whole Clan: Hometown Infrastructure and Nepotism in an Autocracy

This paper studies nepotism by government officials in an authoritarian regime. We collect a unique dataset of political promotions of officials in Vietnam and estimate their impact on public infrastructure in their hometowns. We find strong positive effects on several outcomes, some with lags, including roads to villages, marketplaces, clean water access, preschools, irrigation, and local radio broadcasters, as well as the hometown’s propensity to benefit from the State’s “poor commune support program”. Nepotism is not limited to only top-level officials, pervasive even among those without direct authority over hometown budgets, stronger when the hometown chairperson’s and promoted official’s ages are closer, and where provincial leadership has more discretionary power in shaping policies, suggesting that nepotism works through informal channels based on specific political power and environment. Contrary to pork barrel politics in democratic parliaments, members of the Vietnamese legislative body have little influence on infrastructure investments for their hometowns. Given the top-down nature of political promotions, officials arguably do not help their tiny communes in exchange for political support. Consistent with that, officials favor only their home commune and ignore their home district, which could offer larger political support. These findings suggest that nepotism is motivated by officials’ social preferences directed towards their related circles, and signals an additional form of corruption that may prevail in developing countries with low transparency.nepotism, infrastructure construction, official’s hometown, political connection,political promotion, social preference, directed altruism

On the Precipice: Prospects for Free Labor Unions in Vietnam

Vietnam (officially, the “Socialist Republic of Vietnam”) is rapidly transitioning economically, in large part due to pro-trade policies that have attracted international capital. A necessary component for Vietnam to further integrate into the world economy is to develop a system of industrial relations that will ensure industrial stability and reassure international manufacturers that there is no risk of embarrassment resulting from revelations of brutal or unsafe working conditions. Positive signs for rapid labor reform were visible as recently as early 2016 with the Trans-Pacific Partnership (“TPP”), a trade agreement intended to integrate trade among twelve countries (including Vietnam), which would have set international benchmarks and a fixed deadline for labor reform. Notwithstanding the death of the TPP, labor reform in Vietnam continues, as there is currently a vigorous debate within the country over which direction reform should take. Thanks to labor scholars such as Cynthia Estlund, international labor scholars have a fairly decent idea about the progress and direction of labor law reform in China; however, this is not true for Vietnam, which is poised to become Southeast Asia’s next economic powerhouse. The purpose of this article is to fill this gap. Part II of this article describes how the ILO and the TPP jump-started the most recent wave of labor reform in Vietnam. Part III describes the existing labor regime in Vietnam. Part IV analyzes Vietnamese labor law, specifically as compared to the ILO norms, and explains that although Vietnam has made rapid and radical progress over the last two decades, there is still room for significant improvement. Part V describes and evaluates current proposals for reform. Part VI provides a conclusion of the issues discussed

DISTORTION-BASED HEURISTIC METHOD FOR SENSITIVE ASSOCIATION RULE HIDING

In the past few years, privacy issues in data mining have received considerable attention in the data mining literature. However, the problem of data security cannot simply be solved by restricting data collection or against unauthorized access, it should be dealt with by providing solutions that  not only protect sensitive information, but also not affect to the accuracy of the results in data mining and not violate the sensitive knowledge related with individual privacy or competitive advantage in businesses. Sensitive association rule hiding is an important issue in privacy preserving data mining. The aim of association rule hiding is to minimize the side effects on the sanitized database, which means to reduce the number of missing non-sensitive rules and the number of generated ghost rules. Current methods for hiding sensitive rules cause side effects and data loss. In this paper, we introduce a new distortion-based method to hide sensitive rules. This method proposes the determination of critical transactions based on the number of non-sensitive maximal frequent itemsets that contain at least one item to the consequent of the sensitive rule, they can be directly affected by the modified transactions. Using this set, the number of non-sensitive itemsets that need to be considered is reduced dramatically. We compute the smallest number of transactions for modification in advance to minimize the damage to the database. Comparative experimental results on real datasets showed that the proposed method can achieve better results than other methods with fewer side effects and data loss

Application of geospatial technologies in constructing a flash flood warning model in northern mountainous regions of Vietnam: a case study at TrinhTuong commune, Bat Xat district, LaoCai province

The model was constructed based on GIS spatial analyses, combined with Analytic Hierarchy Process (AHP) and Multi-Criterion Analysis method (MCA). The data gathered for the study were mainly from remote-sensing images, statistical data and surveys. Field experiments were conducted in Trinh Tuong Commune, Bat Xat District, Lao Cai province. This is a typical remote mountainous region of Vietnam in which flash floods often occur. The study analyzes and evaluates six primary factors that incite flash flood, namely: geomorphological characteristics, soil properties, forest and fractional vegetation cover types, local drainage basin slopes, maximum average rainfall of various years, and the river/stream density of the region. The zoning map showing flash flood potentials has determined that 19.91% of the area had an extremely high risk of flash flood occurrence, 64.92% of the area had a medium risk, and 15.17% had a low or very low risk. Based on the employment of daily maximum rainfalls as the primary factor, an online flash flood warning model was constructed for areas with a “high” or “very high” risk of flash flood occurrence.

Treatment-related brain tumor imaging changes: so-called "pseudoprogression" vs. tumor progression: Review and future research opportunities

pre-printBackground: Glioblastoma multiforme (GBM) has a dismal prognosis despite aggressive therapy. Initial diagnosis and measurement of response to treatment is usually determined by measurement of gadolinium-enhanced tumor volume with magnetic resonance imaging (MRI). Unfortunately, many GBM treatment modalities can cause changes in tumor gadolinium enhancement patterns that mimic tumor progression. The lack of a definitive imaging modality to distinguish posttreatment radiographic imaging changes (PTRIC), including pseudoprogression and radiation necrosis, from true tumor progression presents a major unmet clinical need in the management of GBM patients. Methods: The authors discuss current modalities available for differentiating PTRIC and tumor progression, describe development of an animal model of PTRIC, and consider potential molecular and cellular pathways involved in the development of PTRIC. Results: An animal model using glioma cells transfected with a luciferase reporter has been developed, and after conventional GBM therapy, this animal model can be evaluated with posttreatment bioluminescence imaging and various MR tumor imaging modalities. Conclusions: Posttreatment radiographic changes that mimic tumor progression can infl uence clinicians to make treatment decisions that are inappropriate for the patient's actual clinical condition. Several imaging modalities have been used to try to distinguish PTRIC and true progression, including conventional MRI, perfusion MRI, MR spectroscopy, and positron emission tomography (PET); however, none of these modalities has consistently and reliably distinguished PTRIC from tumor growth. An animal model using glioma cells transfected with a luciferase reporter may enable mechanistic studies to determine causes and potential treatments for PTRIC

Child maltreatment in Vietnam : prevalence, risk factors, and consequences

This study investigated the prevalence of child maltreatment in a cross-cultural perspective, the changes in prevalence estimates in Vietnam over time, child and family risk factors of maltreatment, and possible consequences of child maltreatment. We administered questionnaires and a working memory test to 1,851 secondary and high school students (12-17 years old) in four Northern provinces of Vietnam. We compared current Vietnamese prevalence estimates with those from the Dutch prevalence study on child maltreatment (NPM-2010) and from a prevalence study in Vietnam 10 years ago to achieve a cross-cultural and chronological comparison. We found that although there was a decrease in emotional and physical abuse over time, all types of child maltreatment were still highly prevalent, ranging from 2.6% for sexual abuse to 31.8% for emotional abuse. Most types were more common in Vietnam than in the Netherlands. Only the past year sexual abuse prevalence in Vietnam was lower. Single parenthood, being a boy, and older age were risk factors for child maltreatment. Child maltreatment was related to negative child well-being aspects with the largest effect on emotional functioning. Our study draws a clearer picture on child maltreatment in Vietnam. It highlights the importance of prompt responses to child maltreatment.the Netherlands Fellowship ProgrammesDevelopment Psychopathology in context: famil

Determinants Influencing Liquidity of Listed Steel Firms in Vietnam

This study is conducted to investigate the impact levels of determinants influencing liquidity of listed steel firms on Vietnam Stock Exchange. Data were collected from audited financial statements of 25 listed food processing firms from 2014 to 2017. This research employs the least squares method (OLS) and tests to determine the influence of factors on the liquidity of listed sample firms. The results indicate that return on assets (ROA), operating period (AGE) and asset structure (AS) have positive impacts on the liquidity. In contrast, the firm size and debt ratio has the opposite effects. Based on the findings, a number of recommendations are proposed to increase the liquidity ratio of listed firms in the future. Keywords: Liquidity, steel firms, determinants, Vietnam Stock Exchange DOI: 10.7176/EJBM/11-7-10 Publication date:March 31st 201

One Mandarin benefits the whole clan: hometown favoritism in an authoritarian regime

We study patronage politics in authoritarian Vietnam, using an exhaustive panel of ranking officials from 2000 to 2010 to estimate their promotions’ impact on infrastructure in their hometowns of patrilineal ancestry. Native officials’ promotions lead to a broad range of hometown infrastructure improvement. Hometown favoritism is pervasive across all ranks, even among officials without budget authority, except among elected legislators. Favors are narrowly targeted toward small communes that have no political power, and are strengthened with bad local governance and strong local family values. The evidence suggests a likely motive of social preferences for hometown
