Encrucijada y conflicto. Urbanización, conservación y ruralidad en los cerros Orientales de Bogotá
Authors: Meza Carlos Andrés
Published: October 2020

El artículo estudia los cerros Orientales de Bogotá como un complejo de regímenes de territorialidad y experiencias histórico-sociales heterogéneas y conflictivas entre sí a lo largo del tiempo. La cuenca del río Teusacá es el contexto micro regional en la transición entre Bogotá y la región oriental, y sirve de caso para identificar la superposición y el conflicto de territorialidades asociadas a la conservación de la naturaleza, la expansión urbana y la ruralidad. Un análisis de los diferentes regímenes de construcción territorial a lo largo del siglo veinte permite vislumbrar la encrucijada y el conflicto que caracteriza a los cerros orientales de Bogotá en este nuevo siglo.
Paulina Montaño demanda su libertad. Aproximación a una etnografía performativa de un pleito judicial, Chocó, 1738
Authors: Leal Bernardo
Published: October 2020

Con base en el pleito que la esclava Paulina Montaño entabló en contra de su amo Juan Caysedo, en el Chocó, entre 1738 y 1739, examino las posibilidades de intervención de los esclavos en la producción de los documentos, sus posibilidades para proseguir un juicio asimétrico en contra de sus propietarios y las acciones seguidas para obtener la libertad. Para estudiar el caso me apoyo en la “etnografía performativa”, la cual me brinda herramientas para una lectura distinta del proceso judicial.
El uso ritual de yajé: patrimonialización y consumo en debate
Authors: Caicedo Fernández Alhena
Published: October 2020

Desde hace cerca de 15 años varias ciudades colombianas como Bogotá, Medellín, Cali y Pasto han presenciado la aparición y diseminación de rituales asociados a la toma de yajé, un psicotrópico usado tradicionalmente por varios grupos indígenas del piedemonte amazónico. Estas prácticas convocan, en la actualidad, a personas de diferentes clases sociales, quienes acceden a estos espacios con propósitos diversos, donde lo terapéutico y lo espiritual predominan. Ofrecido bajo el rótulo de “medicina tradicional indígena”, el consumo ritual de yajé se promueve como una práctica legítima fruto de una herencia cultural compartida que debe recuperarse. Este artículo presenta algunas discusiones alrededor de la pregunta: ¿es posible pensar el uso ritual de yajé como patrimonio?
Editorial: Corporate governance and ownership: Changing towards an accountable, sustainable, responsible but profitable corporation
Authors: Guedes Maria João
Published: October 2020

In recent years, corporate governance has been a popular topic of research, especially in the aftermath of corporate scandals and financial crisis. These events highlighted the effects that weak corporate governance may have in corporations, resulting in poor management decisions and financial performance, and even ending in the collapse of some corporations. This new issue (volume 18, issue 1) of the journal Corporate Ownership and Control contains an interesting selection of articles, with contributions on the role of different types of ownership (e.g., family and state-owned enterprises) and corporate governance mechanism, from internal control to new forms of socially responsible accountability in order to enable the corporations to ensure a commitment to all stakeholders and a safe global environment for the future.
Differential transcendence of solutions of systems of linear differential equations based on total reduction of the system
Authors: Jovovic Ivana
Published: October 2020

In this paper we consider total reduction of the nonhomogeneous linear system of operator equations with constant coefficients and commuting operators. The totally reduced system obtained in this manner is completely decoupled. All equations of the system differ only in the variables and in the nonhomogeneous terms. The homogeneous parts are obtained using the generalized characteristic polynomial of the system matrix. We also indicate how this technique may be used to examine differential transcendence of the solution of the linear system of the differential equations with constant coefficients over the complex field and meromorphic free terms.
External Jensen-type operator inequalities via superquadraticity
Authors: Kian Mohsen , Krnic Mario , Delavar Mohsen
Published: October 2020

In this paper we establish several Jensen-type operator inequalities for a class of superquadratic functions and self-adjoint operators. Our results are given in the so-called external form. As an application, we give improvements of the H?lder-McCarthy inequality and the classical discrete and integral Jensen inequality in the corresponding external forms. In addition, the established Jensen-type inequalities are compared with the previously known results and we show that our results provide more accurate estimates in some general settings.

Published: October 2020

Haptoglobin (Hp) is a hemoglobin-binding protein that prevents free hemoglobin-induced tissue oxidative damage. In streptozotocin-induced diabetic rats, the initial elevation of Hp expression in the serum and liver tends to decrease with diabetes progression, contributing to increased oxidative stress. Glucose toxicity and diabetic complications are closely related to increased modification of nucleocytoplasmic proteins by O-linked-N-acetylglucosamine (O-GlcNAc). We examined the contribution of O-GlcNAcylation of NF-?B p65 to changes in liver Hp expression in diabetic rats. WGA-affinity chromatography revealed a progressive increase in O-GlcNAcylation in nuclear NF-?B p65 during eight weeks of diabetes. DNA-affinity chromatography followed by immunoblot analysis revealed that decreased Hp expression at 4 and 8 weeks of diabetes was accompanied by the absence of Hp gene hormone-responsive element (HRE) occupancy with NF-?B p65, low occupancy with glucocorticoid receptor (GR), and almost no changes in STAT3 occupancy compared to 2 weeks, when Hp expression was highest. Coimmunoprecipitation experiments indicate that these events were the result of impaired NF-?B p65/STAT3 and GR/STAT3 interactions. Results suggest that the attenuation of Hp expression associated with diabetes was at least in part the result of O-GlcNAcylation of NF-?B p65, which prevents the formation of an effective transcription initiation complex on the Hp gene promoter.

Published: October 2020

Introduction. There are not many cases among acute type-A aortic dissection survivors who get to be called ?incredible.? Here we present such a case followed-up for more than five years. Case outline. A 48-year-old male with acute type A aortic dissection, complicated with cardiac tamponade and severe aortic valve regurgitation, was submitted to emergent surgical treatment. Distal reconstruction was performed by complete aortic arch replacement with ?elephant trunk? extension and separate arch branch bypasses, while the proximal reconstruction was done with Bentall procedure. Total of 11 anastomoses was necessary to complete this procedure. Straight profound hypothermic (18o C) circulatory arrest, with a saturation of the venous blood from the jugular bulb of 97%, lasted 133 minutes. The patient was discharged stable without any neuro-cognitive deficit. Two years later, he was admitted with late prosthetic valve endocarditis and subvalvular abscess. Good response on treatment with efficient combined antibiotics and stabile hemodynamic allowed us to avoid barely feasible re-do surgery. Subvalvular myocardial abscesses evolved into periprosthetic pseudoaneurysms without infectious, thrombo-embolic, or hemodynamic deterioration. The patient is still alive and stable, more than four years after this event. Conclusion. Fortunate outcome of these life-threatening conditions is a reason to reconsider our understanding of cerebral function and metabolism during the profound hypothermic circulatory arrest, and it emphasizes the importance of measuring individual patient response against disease treatment guidelines, as we did, treating the late, complicated prosthetic valve endocarditis with medicaments, instead of high-risk surgery.
Numerical study on the seismic performance of hybrid steel moment frames with CLT balloon shear walls
Authors:   , Khajehpour Mehdi
Published: October 2020

A proposed hybrid lateral load resisting system combining a moderately ductile steel moment resisting frame (SMRF) with Cross-laminated Timber (CLT) balloon-framed shear walls is investigated on 8, 12 and 16-storey case-study buildings using equivalent static, linear dynamic (modal), nonlinear static (push-over) and nonlinear dynamic (time history) analyses. First, a SMRF is designed using ETABS, then the hybrid structures are analysed in OpenSees. By adding the CLT shear wall to steel moment frame, the period of structure decreased and its stiffness increased. The time history analyses result revealed that by adding the CLT shear wall the maximum drift decreased, while the maximum base shear in hybrid structure slightly increased. The hold down uplift forces under earthquake records are reported and compared to each other. Using push-over capacity-curves, a ductility reduction factor of 3.6, an over strength factor of 1.57 and a seismic response modification factor of 5.67 are derived.

Malaria is a disease that occurs in tropical countries like Indonesia. The incidence of malaria in the world is still quite high and the occurrence of cases of Plasmodium resistance to antimalarial drugs and the widespread of resistance have prompted researchers to look for new antimalarial drugs, especially from natural materials. Betel leaf (Piper betle Linn.) And sunflower leaf (Helianthus annuus L.) have long been used by the people of Indonesia as an antimalarial drug. The purpose of this study was to determine antimalarial activity through inhibition of heme polymerization and determine secondary metabolite compounds by phytochemical screening from betel leaves and sunflower leaves. The heme polymerization inhibition activity assay was carried out by the in-vitro method using a microplate reader at 415 nm and 630 nm wavelengths. IC50 values of betel leaf extract and sunflower leaf were 178.67 μg/ml and 160.10 μg/ml, respectively. Phytochemical screening results from betel leaf showed the presence of flavonoids, polyphenols, tannins, quinones, saponins, and monoterpenoids-sesquiterpenoids, while sunflower leaves contain alkaloids, polyphenols, flavonoids, steroids and monoterpenoids-sesquiterpenoids.Keywords: Piper betle Linn., Helianthus annuus L., Malaria, Heme Polymerization

Unremarkable but Crucial: Motivating Employees in Business as Usual Work
Authors: Cheong Matthias
Published: October 2020

'Business as usual' refers to the daily, mundane but necessary operational tasks performed by companies both large and small. While technology and automation have gone a large way towards reducing its necessity, some tasks still need to be performed by a human. Employees have typically shunned such roles as uninteresting, unrewarding, and unlikely to lead to career growth or recognition within the company.  This in turn leads to low levels of motivation when performing such tasks, giving rise to a greater risk of mistakes being made, or poor performance. This paper examines one typical team in the Singapore finance industry, highlighting the difficulties of motivating employees in performing such unremarkable but crucial tasks, and proposing some possible solutions that may be adopted.

Reform in Economic Institution to Promote Restructuring and Changing the Economic Growth Model
Authors: TRẦN DU LỊCH
Published: October 2020

Despite its continuous improvements in the past 25 years, Vietnam?s economic institutions failed to act as a dynamic of economic restructuring and changes in economic growth model in the coming period. When the state fails to identify its functions and duties at all levels in economic management, it cannot control effectively all operations in the market. The state will be slow to change its habits of intervening in the market with its administrative decisions instead of indirect regulatory instruments used for dealing with market defects. In this paper, the author analyzes, interprets and make suggestions about two major issues: (1) Changes in concepts of economic functions of the state in the market economy; and (2) Effective use of macroeconomic regulatory instruments.
Policy on Planning and Promotion of Development of Supporting Industries for Vietnam
Authors: NGUYỄN TRỌNG HOÀI , HUỲNH THANH ĐIỀN
Published: October 2020

This research aims at analyzing aspects determining supporting industries (SIs) to serve the task of planning and developing such industries. Analyses show that Vietnamese SIs are very small and unable to help the manufacturing sector increase its added value and join the global value chain. The results find the following culprits: the plan and policies on SI development are not compatible with main trends of market specialization and global value chain; chain of domestic industrial production is till lacking; and inter-industry cooperation is poor. Policy recommendations, therefore, are as follows: establishing the exact list of SIs that help increase the added value of local industrial production and integrate into the global value chain; and planning space, time, track, and methods needed for carrying out such policies. Besides the development plan, the paper also offers suggestions about policies to promote SIs, such as legal infrastructure for SI development, design of a value chain for SIs, building of clusters of SIs, and mechanism for promoting SI development.

Authors: TRẦN THỊ HẢI LÝ , DƯƠNG KHA
Published: October 2020

This study was conducted to find evidence of short-term underpricing of initial public offerings (IPOs) and factors that explain the level of underpricing based on IPO samples in the period between January 2005 and July 2012 in Vietnam. The authors found certain evidence to support the underpricing, with the underpricing rate set at 38% and 49%. Having bootstrapping regression model employed, the results showed that the two factors ? the exceeding purchase ratio and the starting price of the auctions ? negatively correlated as expected with underpricing rate while impact of market conditions appeared relatively weak. Other factors such as size, listing lateness, company age, state ownership after IPOs did not correlate with the underpricing levels in Vietnam
Estimated Policy Effects on Vietnam’s Exports to Its Major APEC Trade Partners: A Gravity Model Approach
Authors: ERIC IKSOON IM , Tam Bang Vu
Published: October 2020

This paper carries out an empirical assessment of the effects of a set of policy determinants of Vietnam?s exports to its five major Asia Pacific trade partners (China, Japan, South Korea, Singapore, and US) over 23 years from 1989 to 2011. In doing so, a gravity model is employed, which includes two sets of variables: one for gravity variables, and the other for policy-related variables. The latter includes four policy variables: real exchange rate, trade liberalization, anti-corruption activity, and WTO membership status. The effects of real exchange rate and anti-corruption activity are each specified as a linear function of the degree of trade liberalization to capture the indirect effects of trade liberalization on Vietnam?s exports over time. The effect of trade liberalization on Vietnam?s exports is specified as linear dependent on its WTO membership status to capture its direct effect and the additional effect attributable to Vietnam?s accession to WTO on its exports. We find that Vietnam?s trade liberalization has direct and indirect positive impacts on its trades, and its accession to WTO has a positive effect as well, contrary to some criticism otherwise.
Measuring Growth of Labor Productivity in Vietnam by Shift-Share Analysis of Structure of Industries
Authors: NGUYỄN QUỐC TẾ , NGUYỄN THỊ ĐÔNG
Published: October 2020

This research aims at measuring growth of labor productivity during structural changes in Vietnam in the years 1994-2011. Shift-share analysis of structure of industries shows that growth of labor productivity in Vietnam is a result from the static shift effect. In other words, productivity growth is resulted from changes in structure of industries, in which labors move from low-productivity industries to higher ones. Both endogenous (within-industry) factors and dynamic shift effect seem to be affected by the burden of structure and the backwardness of technology in the process of economic structural changes.
Impacts of Oil Shocks on Vietnam’s Trade Balance and Recommendations
Authors: NGUYỄN KHẮC QUỐC BẢO
Published: October 2020

This paper aims at examining impacts of oil shocks on Vietnam’s balance of trade and causal relationship between the balance of trade and relevant macro factors. Bound testing approach and ARDL are applied to data from Quarter I of 1999 to Quarter IV of 2011. The results demonstrate a negative relationship between oil price, exchange rate and trade balance in Vietnam. More specifically, a one-percent increase in the oil prices and exchange rate causes the trade balance to fall by 0.12% and 0.79% respectively in the long run. In the short run, however, international exchange rates and oil pricesare positively corrrelatedwith Vietnam’s trade balance. These findings allow some recommendations and suggestions for policy makers in an effort to reduce negative effects of oil shocks on Vietnam’s trade balance.
Factors Affecting Liquidity Risk in the System of Vietnamese Commercial Banks
Authors: TRƯƠNG QUANG THÔNG
Published: October 2020

The research tries to identify causes of liquidity risk for the system of Vietnamese commercial banks. Data for the research are collected from annual reports in the years 2002-2011 by 27 Vietnamese commercial banks. The liquidity risk examined in the research is financing gap; and independent variables, or factors affecting the liquidity risk, are divided into two groups: internal and external ones. The estimated results of the models show that the liquidity risk among banks depends not only on internal factors, such as total asset size, liquidity reserve, inter-bank loan, and ratio of equity to capital, but also on external ones, or macroeconomic factors, such as growth rate, inflation, and especially effects of policy lags.
An Evaluation of Relationship between Foreign Direct Investment and Economic Growth in Vietnam
Authors: Phạm Thị Hoàng Anh , Lê Hà Thu
Published: October 2020

Foreign direct investment (FDI) is an essential source of capital in the gross investment conducive to national economic growth, including the case of Vietnam. Since the 1987 Foreign Investment Law, the country has attracted a large amount of foreign capital, which makes a significant contribution to economic development. This research employs a VAR model to analyze the relationship between FDI and Vietnam’s economic growth. The results suggest that FDI has a positive impact on the latter and vice versa. The research also finds that FDI stimulates export and improves the quality of human resources and technology - important prerequisites for the economic growth.

E-banking is an inevitable trend of the banking industry in the future. E-banking benefits not only banks but also customers, so the study of models of adoption and usage of E-banking is essential. Nguyễn & Cao (2011) propose the adoption and usage of E-banking model in Vietnam - E-BAM (E-Banking Adoption Model), and their findings showed that eight following factors - performance expectancy, compatibility, perceived ease of use, perceived behavioral control, subjective norm, perceived risk in transaction, bank image, and macro impact of law - affect the E-banking adoption and E-banking adoption affects E-banking usage. However, according to some relevant theoretical models, this model does not show relationships among independent variables and the effects of independent variables on the E-banking usage. In this paper, authors re-propose a new model of E-BAM to overcome the limitations of the 2011 research, the relationships in the model were analyzed by linear structural model - SEM (Structural Equation Modeling). Factors including perceived behavioral control, compatibility, performance expectancy, bank image and perceived risk in transaction are mutually influenced and affect the E-banking adoption intention; while perceived ease of use and E-banking adoption affect the E-banking usage.

Authors: Trần Thị Thuỳ Linh , Tạ Thị Thuý
Published: October 2020

The research aims to analyze the impact of financing decisions on investment ones and examine the relationships between leverage, debt maturity structure, investment and growth opportunities. A system-based model is employed, including three structural equations in which leverage, debt maturity and investment are adopted as endogenous variables. The research data consist of 100 enterprises listed on HOSE and HNX in the period 2007-2012. The results indicate that financial leverage negatively correlates with investment decisions, whereas no correlation is revealed between debt maturity and corporate investment, which is compliant with findings by Dang (2011) and Aivazian et al. (2005). Accordingly, for Vietnamese enterprises, there exists an interaction among leverage, debt maturity and investment. Financial leverage and debt maturity are used as alternative strategies to control corporate liquidity.

Published: October 2020

Employing data for the years 2006–2011, the research analyzes the relationship between Provincial Competitiveness Index (PCI) ranking and development of enterprises in certain Vietnamese provinces. The results show that the data do not demonstrate the relationship between the PCI ranking and indexes of development of enterprises. This implies that great caution should be taken when interpreting the PCI ranking of a province, especially in treating the PCI as a driving force for the provincial economic development.

Published: October 2020

Establishing loan loss provisions may affect bank’s profitability and capital adequacy ratio. The paper employs regression analysis to explore operations of loan loss provisions in Vietnamese commercial banks in 2008-2012 in its relationship with bank characteristics. The results show that loan loss provisions of Vietnamese commercial banks are positively related to size and proportion of bad debt and negatively related to financial risk ratio. The paper provides theoretical evidence of the opportunism in selection of accounting policy concerning loan risk management by Vietnamese bank managers.

Factors Affecting the Propensity to Create Budgetary Slack Evidence from Vietnamese Enterprises
Authors: Trinh Hiep Thien
Published: October 2020

Budgeting is widely advertised as an effective managerial accounting tool but has been criticized mainly for budgetary slack reason. The purpose of this article is therefore to empirically examine relationships between budget participation, budget emphasis, risk awareness, private knowledge and the propensity to create budgetary slack. This study also extends the previous research by testing the hypothesized effect of the nonfinancial managerial accounting information use on various factors associated with the propensity to create budgetary slack. A survey data from 243 Vietnamese enterprises was used to conduct a structural equation modeling analysis. The results indicate that budget participation and budget emphasis incrementally affect the propensity to create budgetary slack while nonfinancial managerial accounting information is fairly useful to limit human aspects of budgeting. In addition, no correlation between private knowledge and creation of budgetary slack by subordinates was found. Once again, the results of this research confirm the effects of human factors in budgeting, which measured in a Vietnamese business environment and extended the understanding of the role of nonfinancial managerial accounting information in improving the budgeting process.

Authors: Nguyen Khac Quoc Bao
Published: October 2020

This study aims to assess the factors affecting the incentives for financial risk management in Vietnamese enterprises. By employing multivariable binary logistic regression, the author examines the relationship between hedging decisions for firms’ financial risks and their determinants, namely financial distress costs, tax, agency cost of debt, capital-market imperfections and growth opportunity, hedge substitutes, level of managerial utility, level of government influence, and size of firms. The results demonstrate that hedging decisions for financial risks have a positive correlation with costs of financial distress and managerial utility, and a negative correlation with government influence. These findings are agreeable to empirical results of previous researches that work out on the same case.

Authors: Nguyen Van Bon
Published: October 2020

Foreign direct investment (FDI) has been strongly affecting the world economy during the past years and is a critical topic for both developing and developed countries. Most countries, particularly developing ones, always attempt to adjust and modify appropriate policies and institutions to attract FDI inflows. In the context of Vietnam, does the institutional quality have any effect on attracting FDI inflows in provinces? To answer clearly and exactly this question, the impact of institutional quality on attracting FDI inflows is empirically investigated in a sample of 43 provinces of Vietnam over the period of 2005–2012 via the estimation technique of difference panel GMM. Estimated results indicate that in the total sample of all provinces the institutional quality has significantly positive effects on the FDI flows. However, in the sub-sample of provinces the impact of the institutional quality on attracting FDI inflows in Northern and Southern regions are statistically significant while that in Central region is not.

Building a strategy map helps an enterprise to clearly describe and interpret the content of the strategy, making a premise for selecting key performance indicators (KPIs) and implementing the strategy based on new management models and modern strategic thinking in accordance with the Balanced Scorecard approach. We proposed three groups of strategies and built three following strategy maps: (i) strategy of developing high added-value products, (ii) strategy of ensuring the possibly lowest international outsourcing cost, and (iii) strategy of target customer orientation. This paper is intended as a contribution to change the old strategic thinking of Khanh Hoa aquatic product processing enterprises and help them to navigate and describe the strategy clearly and to develop sustainably in a globally competitive context.
