Impacts of Payment for Forest Ecosystem Services on Local livelihoods in A Luoi District, Thua Thien Hue Province, Viet Nam

This paper analyses the impacts of the national Payment for Forest Environmental Services (PFES) policy in A Luoi district, Thua Thien Hue province, Viet Nam. There are mixed impacts of PFES in A Luoi district. While some surveyed households have experienced increases in income since PFES, for many other incomes have fallen. Our findings show PFES impacts on local communities and individuals are limited because most forest areas are managed by state agencies, leaving only 17.9% of PFES payments being channeled to these groups, while the rest goes to state government agencies and commune people’s committees. This disparity in PFES payments has further widened the income gap between state agencies and local households.  PFES payments currently contribute little to household incomes, averaging only 2.64% of total earnings. PFES has little impact and additionality in advancing land tenure security and reducing natural forest product exploitation for generating income as impacts are similar to those found in non-PFES villages. PFES poverty reduction impacts vary from village to village, but in general, percentages of poor households receiving PFES payments range from 1% to 59%

Activated carbon derived from rice husk by NaOH activation and its application in supercapacitor

AbstractFour activated carbon (AC) samples prepared from rice husk under different activation temperatures have been characterized by N2 adsorption–desorption isotherms, thermogravimetric analysis (TGA–DTA), Fourier transform infrared spectroscopy (FTIR) and scanning electron microscopy (SEM). The specific surface area of AC sample reached 2681m2g−1 under activation temperature of 800°C. The AC samples were then tested as electrode material; the specific capacitance of the as-prepared activated carbon electrode was found to be 172.3Fg−1 using cyclic voltammetry at a scan rate of 5mVs−1 and 198.4Fg−1 at current density 1000mAg−1 in the charge/discharge mode

Antidepressive and anxiolytic effects of ostruthin, a TREK-1 channel activator

We screened a library of botanical compounds purified from plants of Vietnam for modulators of the activity of a two-pore domain K+ channel, TREK-1, and we identified a hydroxycoumarin-related compound, ostruthin, as an activator of this channel. Ostruthin increased whole-cell TREK-1 channel currents in 293T cells at a low concentration (EC50 = 5.3 μM), and also activity of the TREK-2 channel (EC50 = 3.7 mM). In contrast, ostruthin inhibited other K+ channels, e.g. human ether-à-go-go-related gene (HERG1), inward-rectifier (Kir2.1), voltage-gated (Kv1.4), and two-pore domain (TASK-1) at higher concentrations, without affecting voltage-gated potassium channel (KCNQ1 and 3). We tested the effect of this compound on mouse anxiety- and depression-like behaviors and found anxiolytic activity in the open-field, elevated plus maze, and light/dark box tests. Of note, ostruthin also showed antidepressive effects in the forced swim and tail suspension tests, although previous studies reported that inhibition of TREK-1 channels resulted in an antidepressive effect. The anxiolytic and antidepressive effect was diminished by co-administration of a TREK-1 blocker, amlodipine, indicating the involvement of TREK-1 channels. Administration of ostruthin suppressed the stress-induced increase in anti-c-Fos immunoreactivity in the lateral septum, without affecting immunoreactivity in other mood disorder-related nuclei, e.g. the amygdala, paraventricular nuclei, and dorsal raphe nucleus. Ostruthin may exert its anxiolytic and antidepressive effects through a different mechanism from current drugs

The Impact of Supporting Industries on Attracting Foreign Direct Investment: A Case Study in Vinh Phuc Province, Vietnam

 Summary: This study focuses on explaining the theoretical basis of the impact of supporting industries (SI) on attracting foreign direct investment (FDI); assessing the state of the impact of SI on FDI attraction into Vietnam in general and Vinh Phuc province in particular. Quantitative analysis results show that, in the field of SI in Vietnam, import suppliers are dominating domestic suppliers, the factor that most affects FDI enterprises' satisfaction level is labor, especially hard-work and progressiveness, followed by quality and attitude of discipline compliance of labor resources. The domestic SI still face difficulties in approaching customers, quality assurance, with outdated technology, lack of high-tech manpower, poor innovative research capabilities... In the coming time, to contribute to FDI attraction into Vietnam, to become a supplier for FDI enterprises, domestic enterprises working in supporting industries (SI enterprises) need to increase the rate of capital investment on technology, improve the quality of human resources, and promote information exchange with FDI enterprises

Reading culture is extremely important in the process of studying and researching in universities. As a factor promoting the process of self-study, student research helps to innovate teaching and learning methods in the direction of learner-centered. The following article presents issues about the current situation of the reading culture of students - students studying at Thanh Hoa University of Culture, Sports and Tourism. Outline strengths, limitations and propose a solution. Some solutions contribute to the development of reading culture for students - students at the school

Policies on Inclusive Education for Children with Disabilities in Vietnam

This article traces the history of inclusive education policy development, laws that have been promulgated, and the dissemination of policy and legal rights and responsibilities through conferences, seminars and university coursework in Vietnam since 1995 when the responsibility for educating children with disabilities shifted from the Ministry of Labor, Invalids and Social Affairs to the Ministry of Education and Training. Numerous standards of practice related to roles and responsibilities and recommendations for improvemtns in policy and practice are shared as well as lessons learned from external evaluation efforts that will be valuable for further development and refinement of poilicies to forward inclusive education in Vietnam

Towards a Dynamic Data Structure for Efficient Bounded Line Range Search

Abstract We present a data structure for efficient axis-aligned orthogonal range search on a set of n lines in a bounded plane. The algorithm requires O(log n + k) time in the worst case to find all lines intersecting an axis aligned query rectangle R, where k is the number of lines in range. O(n + λ) space is required for the data structure used by the algorithm, where λ is the number of intersection points among the lines. Insertion of a new rightmost line or deletion of a leftmost line requires O(n) time in the worst case. For a sparse arrangement of lines (i.e., for λ = O(n)), insertion of a rightmost line or deletion of a leftmost line requires O( √ n) time, and O(log n + µ) expected time for µ the number of intersection points between and existing lines
