Effects of Changes in Public Policy on Efficiency and Productivity of General Hospitals in Vietnam

The health sector reform programme which began in Vietnam in 1989 in order to improve the efficiency of the health system has altered the way in which Vietnamese hospitals operate. The programme put the spotlight on input savings. This study aims to examine the relative efficiency of hospitals during the health reform process and assess - by looking at the relative efficiency of hospitals - the effects of the regulatory changes. The study employs the DEA two-stage approach referring to data from 101 general public hospitals over the period 1998-2006. The study revealed that there was evidence of improvement in the productivity of Vietnamese hospitals over the period 1998-2006, with a progress in total factor productivity of 1.4% per year. Furthermore, the differences in hospital efficiency can be attributed to both the regulatory changes and hospital-specific characteristics. The user fees and autonomy measures were found to increase technical efficiency. Provincial hospitals were revealed to be more technically efficient than their central counterparts and hospitals located in the North East, South East and Mekong River Delta regions performed better that hospitals from other regions

Using Quizlet to Engage the Students in Learning Vocabulary

Utilizing Natural and Man-made Resources for Economic Development: What Are the Mechanisms and Why?

This dissertation studies the roles of natural resources in determining economic outcomes such as innovation, investment, profitability and economic growth. The first chapter studies the ease of substitution between energy and other production inputs over time and across countries. Improvements in energy efficiency over the past decades have substantially decreased the amount of energy used per unit of capital. Yet, previous literature often assumes a constant elasticity of substitution between capital and energy. In this chapter, we develop a Solow growth model with a variable elasticity of substitution (VES) between production inputs and show that the long-run growth rate directly depends on the behavior of this VES over time. Next, using country-level data from 108 countries between 1971 and 2011, we provide the first empirical evidence for a capital-energy VES. Specifically, the elasticity of substitution between capital and energy positively relates to a country\u27s level of economic development and environmental protection efforts. Our results imply that growth-enhancing policies can ease the substitution between capital and energy, which in turn can foster long-run economic growth. In the second chapter, I study the risk and return behavior of green bonds, a new financial instrument that supports green projects around the world. Since its inception in 2007, the green bond market has experienced a compound growth rate of 50% annually. In 2014, green bond issuance totaled USD 36.6 billion, more than threefold its previous year\u27s level of USD 11 billion. This paper is the first to analyze the volatility behavior of the green bond market using data on daily closing prices of the S&P green bond indices between April 2010 and April 2015. Building on a multivariate GARCH framework, I find that compared to the ``labeled\u27\u27 segment of the green bond market, the ``unlabeled\u27\u27 segment experiences smaller volatility clustering. I also found a time-varying spillover effect between the green bond market and the overall conventional bond market. These results are meaningful insights into this new, yet very promising market, therefore, have important implications for asset pricing, portfolio management and risk management. The third chapter evaluates the role of a fossil fuel tax and research subsidy in directing innovation from fossil fuel toward renewable energy technologies in the electricity sector. Using a global firm-level electricity patent database from 1978 to 2011, we find that the impact of fossil fuel taxes on renewable energy innovation varies with the type of fossil fuel. Specifically, a tax on coal reduces innovation in both fossil fuel and renewable energy technologies while a tax on natural gas has no statistically significant impact on renewable energy innovation. The reason is that easily dispatchable energy sources (e.g., coal-fired power) need to complement renewable energy technologies (e.g., wind or solar) in the grid because renewables generate electricity intermittently. Our results suggest that a tax on natural gas, combined with research subsidies for renewable energy, may effectively shift innovation in the electricity sector towards renewable energy. In contrast, coal taxation or a carbon tax that increases coal prices has unintended negative consequences for renewable energy innovation. Finally, the last chapter of my dissertation takes a closer look at the efficiency of firms in developing countries. The private sector is the primary source of employment and local development in developing countries. Previous research in developing countries has documented a number of factors contributing to firm-level efficiency. However, which of these factors are the most important drivers of efficiency? This paper ranks the relative importance of the firm-level efficiency determinants in a transitional economy, using a comprehensive firm-level panel data set in Vietnam between 2005 and 2013. The empirical results show that firm-specific production and labor characteristics are the most significant determinants of efficiency. In contrast, legal factors such as formalization and government financial support play a modest role, due to the crowding-out effect of corruption. Thus, firms actively seeking to improve their own production process and labor force can be well-rewarded. Moreover, government technical supports and human resource training programs, combined with anti-corruption efforts, are beneficial for firm-level efficiency, thereby improving the living standards in developing economies

DYNAMIC ENHANCEMENT OF THE FUTURE SASKPOWER INTERCONNECTED NORTH AND SOUTH SYSTEMS: THE HVDC INTERCONNECTION

SaskPower has two separate systems, namely the North and the South systems. The South system contains SaskPower major generation and system load. The North system load is located relatively far from its generation (200 to 300 km). The North system is considered, therefore, to be electrically weaker than the South system. Recently there has been an interest in connecting the two systems to improve the security, stability and reliability of the integrated system. Grid interconnections, however, especially between weak and strong systems, often result in the arising of low-frequency oscillations between the newly connected areas. These oscillations that are termed “inter-area oscillations” exhibit, generally poor damping and can severely restrict system operations by requiring the curtailment of electric power transfers level as an operational measure. There are two options for SaskPower North and South systems interconnection, namely HVAC and HVDC interconnections (tie-lines). This thesis reports the results of digital time-domain simulation studies that are carried out to investigate the dynamic performance of a proposed 260 km, ± 110 kV, 50 MW Voltage-Sourced Converter HVDC tie-line that would connect SaskPower North and South systems. The potential problems that might arise due to such an interconnection, namely power flow control and low-frequency oscillations are studied and quantified and a proposed feasible solution is presented. In this context, the effectiveness of the HVDC and a Power Oscillations Damping (POD) controller in damping power system oscillations in the tie-line is investigated. Time-domain simulations are conducted on the benchmark model using the ElectroMagnetic Transients program (EMTP-RV). The results of the investigations have demonstrated that the presented HVDC link and its POD controller are effective in mitigating the low-frequency oscillations between the North and South systems at different system contingencies and operating conditions

Soft power and the United States' strategic "rebalancing" to the Asia-Pacific region

Power in international relations can be defined in several different ways. Power can be understood as a goal of states or leaders involving a measure of influence or control over outcomes, events, actors and issues; achieving victory in conflict and the attainment of security; control over resources and capabilities; or status, which some states or actors possess and other do not. Modern discourse in international relations generally speaks in terms of state power, indicating both economic and military power. The capabilities to handle those above functions are different from state to state and can be measured in different ways as well as with respect to different dimensions, among which “hard” and “soft” power can be taken into consideration. In the policy-making process of any states, hard power and soft power strategies are rarely separated but they are, in fact, closely related. The relationship between hard power and soft power has become an increasingly popular topic both inside and outside the USA in considering how to strengthen its status in the world arena, particularly in the Asia-Pacific region. American politicians, businessmen and scholars have constantly stressed the need and the opportunities of using soft power instead of hard power to manage the USA’s international relations, especially in this important region. The policy of the U.S. government towards this region is reflected through its strategic rebalance towards the Asia-Pacific region, which was announced by the Obama Administration in 2010. Since it came into being, this strategy has been described by several names including “return”, “pivot” or “rebalancing to Asia”. Although the strategy may be referred to by different names, it aims at describing the new prioritization in the foreign and national security policy of the United States. In order to examine the importance of both “hard” and “soft” power in international relations, American soft power and the implementation of its soft power in the “rebalancing” strategy, four research questions come to mind. They are: 1. What are the definitions soft power and hard power in international relations? 2. How does the US make use of both hard and soft power in building its capabilities and position in the region of Asia-Pacific? 3. What are the US’s intentions in its announced shift in focus to the Asia-Pacific region? 4. What are the regional responses to the US’ policy including by Vietnam? 5. What ensures the future success of the rebalance in the region? Due to the US’s growing emphasis on the use of soft power, the research will focus specifically on two questions; what are the soft power strategies of the US in this region; and what are Vietnam’s attitudes towards these strategies. If one can distinguish soft power elements in this policy shift, it is still important to consider the role of hard power elements and what larger regional role the US will play if its policy shift is successful. The focus of the research is on US actions and will exclude the effects of the policy on domestic policies in the Asia-Pacific, with the exception of briefly summarizing the changing stance of regional countries, thereby, showing the effects of American soft power on the region and on the US itself. Before examining the research questions, a theoretical framework will be provided in the first section of this paper discussing the content of hard power and soft power as described by several political analysts and theorists. This aims at giving an idea of the numerous definitions attached to hard and soft power as well as to lay out the analytical tools for the third section in which the “pivot” in the US’s Asia-Pacific policy will be examined. In the next section, regional attitudes towards the US’ “rebalancing” strategy, especially Vietnam’s, will be surveyed. The thesis will conclude with a discussion on whether these strategies are in line with the US’s use of soft power with their policies in other parts of the world and why the use of soft power, which can help to ensure the successes of this policy direction, does not yet seem to have received adequate attention. The significance of the study will be to enhance understanding of the role of hard and soft power in building the US’s status in the world arena, especially in realizing its “return to Asia” strategy. Moreover, this study may interest those whose work is closely related to the US and its policies, especially in the Asia-Pacific region, enabling them to have more understanding, which they can use to initiate appropriate strategies in their work. It is obvious from the broad audiences above that a census is not feasible for this study. Accordingly, the research approach includes informal interviews in which a sample from the target population of interested parties is used for the study. In total, a sample of 20 was selected. First, the target population was divided into political leadership, governmental officials and other relevant peoples in the Asia-Pacific region. Then they were grouped into those who are experienced, non-experienced and little experienced in working with the US. This ensured a fair representation of each group since their understanding and experiences are significantly different. The focus of the study is on personal attitudes and perceptions and the importance of primary data cannot be over-emphasized. Before the collection of actual data, the researcher sent introductory letters from the Vietnam Union of Friendship Organizations to the sampled offices and institutions. The initial visit to the selected offices and institutions was therefore to introduce the researcher, obtain familiarity with those offices and institutions as well as seek their consent for the study. The researcher collected data by administering a questionnaire. The questionnaire used open questions, consisting of five questions seeking to answer research questions related to soft power and the U.S. rebalance to the Asia-Pacific. The results of the study should provide interested parties with a panorama of the US’s “return to Asia” strategy, its contributions to development in relations between the US and the region’s countries and Vietnam’s responses to it with specific respect to its soft power elements. In particular, the insights yielded by the study into the role of soft power should tell much about the likely success of this policy and its implications for those in the region who interact with the US. Although this research was carefully prepared, it still has some limitations. First, the research was conducted in such a short time that it was not possible for the researcher to read all the materials related to the topic. Therefore, the thesis cannot reflect all aspects of the issue. Second, the population of the sample population was small, only 20. In addition, since the researcher conducted the interviews herself, it is unavoidable that a certain degree of subjectivity can be found in this study

Historical Change of Seagrasses in the Mississippi and Chandeleur Sounds

Seagrasses are important coastal resources facing numerous stressors, and losses have been documented from local to global assessments. Under the broad theme of habitat loss and fragmentation, a study of historical change in total area and landscape configuration of seagrasses in the Mississippi and Chandeleur Sounds was conducted. Mapping data was collated from a multitude of previous projects from 1940 to 2011. Comparisons of seagrass area among various studies that used different mapping methods can result in overestimation of area change and misleading conclusions of change over time. The vegetated seagrass area (VSA) data were generalized to a common resolution for further analysis. Spatial configuration of the seagrass landscape was examined through: (1) an exploratory spatial data analysis using seagrass patch size distribution and hot spot analysis, and (2) a core set of seagrass landscape FRAGSTATS metrics and a principal component analysis to identify major pattern. This study demonstrated a comprehensive analysis across spatial and temporal scales and used multiple landscape indices (from habitat, species composition, VSA, patch size distribution, to spatial configuration at patch- and landscape-levels) to provide insights on the pattern and dynamics of the seagrass landscape. A conceptual model of seagrass landscape change based on two principal factors, overall landscape lushness and continuity, was proposed for the Mississippi Sound. Overall the study area lost seagrasses with contracted spatial extent over the 71-year period, ostensibly due to loss or reduction of protective island barriers and reductions in water quality. The seagrass landscape in the Mississippi Sound exhibited signs of area loss and fragmentation as far back as the 1940-1950s. The landscape in the 1970s was characterized by loss of habitat, loss of seagrass species, the lowest VSA, a faster rate of decline and a higher loss in VSA than before 1970, a low proportion of large-sized patches and their low contribution to VSA, a reduced intensity of hot spots, and a high degree of fragmentation. Recovery of seagrass occurred during the 1980s and 1990s, with the landscape exhibiting characteristics of a more contiguous and more vegetated condition throughout the early 2000s

Organic Smallholder Farming in Northwest Vietnam: A Case Study from Tan Lac District, Hoa Binh Province

This study asks whether organic vegetable production is a suitable alternative farming practice for conventional vegetable farmers in Tan Lac, a mountainous area in the North of Vietnam. The study is motivated by three questions: (1) who among the vegetable farmers in Tan Lac tended to switch to organic vegetable production? (2) is organic vegetable production profitable, compared with conventional production? And (3), what could be done to make organic vegetable production a more sustainable source of income and to help farmers switching to organic farming be more successful? These questions are answered using quantitative and qualitative data collected from a household survey conducted in 2017 that included 95 smallholder farmers. Focus group discussions and key-informant interviews were also used to learn about farming practices and challenges in the area. A series of regressions are used to examine whether organic vegetable production is more or less profitable than conventional vegetable production, and what characteristics are common among farmers who tend to be organic adopters. The results show that organic vegetable production in the study site is less profitable than conventional production. One hectare of organic vegetables is 42 million dong (1840 USD) less profitable than one hectare of conventional vegetables. To help organic farmers in the study site become more successful, (i) farmers need to be aware not only of the benefits but also the challenges when going organic before making the switch; (ii) production sites must be carefully chosen; (iii) a marketing plan should be established when production plans are developed; and (iv) smallholder farmers need to cooperate when producing and selling organic vegetables

Zooplankton from Can Giuoc River in Southern Vietnam

In this study, the variables of zooplankton and water quality were investigated in the Can Giuoc River, Southern Vietnam. Zooplankton was monitored in April and September 2015 at 5 sampling sites in the river. Some basic water quality parameters were also tested, including pH, total suspended solid (TSS), dissolved oxygen (DO), biological oxygen demand (BOD5), inorganic nitrogen (NH4+), dissolved phosphorus (PO43-), and coliform. The zooplankton biodiversity indices were applied for the water quality assessment. The results showed that pH ranged from 6.7 to 7.6 during the monitoring. The TSSs were between 34–117 mg/L. The DO and BOD5 were from 0.6 to 3.8 mg/L and from 6.3 to 13.2 mg/L, respectively. The NH4+ and PO43- concentrations ranged from 0.44 to 3.23 and from 0.08 to 1.85 mg/L, respectively. The coliform number was between 9.3x103–9.3x104 MPN/100 mL. The zooplankton analyses showed that there were 31 species of coelenterates, rotatoria, oligochaetes, cladocerans, copepods, ostracods, mysidacea, and 8 larval types. Thereof, the species of copepods were dominant in the species number. The zooplankton density ranged from 9 500 to 23 600 individuals/m3 with the main dominant species of Moina dubia (Cladocera), Thermocyclops hyalinus, Acartia clausi, Oithona similis (Copepoda), and nauplius copepods. The biodiversity index values during the monitoring were from 1.47 to 1.79 characteristic of mesotrophic conditions of the aquatic environment. Besides, the species richness positively correlated with pH, TSS, DO, BOD5, NH4+, PO43-, and coliform, while the zooplankton densities got a positive correlation with DO, BOD5, NH4+, PO43-, and coliform. The results confirmed the advantage of using zooplankton and its indices for water quality assessment
