Economic Class and Labour Market Inclusion: Poor and Middle Class Workers in Developing Asia and the Pacific

Using an absolute definition of poverty and the middle class, this paper presents trends and estimates of the poor, near poor and middle class working population in developing Asia and the Pacific. It finds that since 1991 working poverty has fallen remarkably while middle class jobs now account for nearly two-fifths of all employment in the region (671 million middle class workers). However, a sizeable share of workers (around 28 per cent or 497 million) still live just above the poverty line and remain highly vulnerable to falling into poverty. The paper also applies a class-based framework for assessing inequality in the labour market, with a special focus on Cambodia, India, Indonesia and Viet Nam. It provides empirical evidence that economic participation is inversely related to affluence, while educational attainment and access to better quality jobs both increase with higher economic class status. In addition, it presents sex- and age-disaggregated analysis to highlight particular gaps for poor women and youth and the measures that can help strengthen their position in the labour market

Impacts of Current Global Economic Crisis on Asia's Labor Market

The paper investigates the labor market and social impacts of the global financial and economic crisis in Asia and the Pacific as well as national policy responses to the crisis. It draws on recent macroeconomic, trade, production, investment, and remittances data to assess the employment and social consequences of the crisis, including falling demand for labor, rising vulnerable and informal employment, and falling incomes and their related pressures on the working poor. The paper provides some projections of the impact on unemployment, vulnerable employment, working poverty, and labor productivity in the region in 2009. It demonstrates that labor market recovery is likely to lag behind output growth, based on the experience of Asian labor markets following the 1997 Asian financial crisis. The paper underscores some policy options that are likely to have positive outcomes toward generating employment and boosting aggregate demand, improving social protection and welfare on the basis of decent work principles, and promoting a sound and sustainable economic and labor market recovery.asian labor market; labor policies; global financial crisis

THE RELATIONSHIP BETWEEN BASELINE CD4 T CELLS’ LEVEL AND RECOVERY RATE AFTER INITIATION OF ART IN HIV/AIDS INFECTED AT HOSPITAL FOR TROPICAL DISEASES, VIETNAM

Objective: HIV/AIDS pandemic continues to be a public health problem in developing countries. This study aimed to assess the correlation of recovery responses and baseline CD4 T cells’ level in HIV/AIDS adult patients after initiation of antiretroviral therapy (ART) in Vietnam. Methods: The study was a clinic-based longitudinal study done at an outpatient clinic, Tropical Diseases Hospital, Ho Chi Minh City, Vietnam, from 10/2018 to 8/2019. Results: Ninety-three patients were provided informed consent to participate in this study. Overall, the mean of CD4 T cell counts was 161.7 cells/μl. In AIDS patients groups, at the baseline mean of T CD4 cell was 65 cells/μl and in the non-AIDS group was 315 cells/μl. The slope of the plotted overall CD4 cell counts increased significantly in both two groups and the steepest increases in the first 3 months. After 6 months, patients who were AIDS stages were had a higher viral load in plasma than others, with p<0.005. The changes in CD4 T cell counts were significantly associated with age and occupational status. Conclusion: The present study found that immunological responses of patients with first-line ART were not related to baseline CD4 T cells’ level. However, low baseline CD4 counts were associated with poor virologic suppression

Millimeter-Wave Concurrent Dual-Band BiCMOS RFIC Transmitter for Radar and Communication Systems

This dissertation presents new circuit architectures and techniques for improving the performance of several key BiCMOS RFIC building blocks used in radar and wireless communication systems operating up to millimeter-wave frequencies, and the development of an advanced, low-cost and miniature millimeter-wave concurrent dual-band transmitter for short-range, high-resolution radar and high-rate communication systems. A new type of low-power active balun consisting of a common emitter amplifier with degenerative inductor and a common collector amplifier is proposed. The parasitic neutralization and compensation techniques are used to keep the balun well balanced at very high frequencies and across an ultra-wide bandwidth. A novel RF switch architecture with ultra-high isolation and possible gain is proposed, analyzed and demonstrated. The new RF switch architecture achieves an ultra-high isolation through implementation of a new RF leaking cancellation technique. A new class of concurrent dual-band impedance matching networks and technique for synthesizing them are presented together with a 25.5/37-GHz concurrent dual-band PA. These matching networks enable simultaneous matching of two arbitrary loads to two arbitrary sources at two different frequencies, utilizing the impedance-equivalence properties of LC networks that any LC network can be equivalent to an inductor, capacitor, open or short at different frequencies. K- and Ka-band ultra-low-leakage RF-pulse formers capable of producing very narrow RF pulses in the order of 200 ps with small rising and falling time for short-range high-resolution radar and high-data-rate communication systems are also developed. The complete transmitter exhibiting unique characteristics obtained from capabilities of producing very narrow and tunable RF pulses with extremely RF leakage and working concurrently in dual bands at 24.5 and 35 GHz was designed. Capability of generating narrow and tunable RF pulses allows the radar system to flexibly work at high and multiple range resolutions. The extremely low RF leakage allows the transmitter to share one antenna system with receiver, turn on the PA at all time, comply the transmitting spectrum requirements, increase the system dynamic range, avoid harming to other systems; hence improving system size, cost and performance. High data-rate in communication systems is achieved as the consequence of transmitting very narrow RF pulses at high rates. In addition, the dissertation demonstrates a design approach for low chip-area, cost and power consumption systems in which a single dual-band component (power amplifier) is designed to operate with two RF signals simultaneously

Outage and bit error probability analysis in energy harvesting wireless cooperative networks

This study focuses on a wireless powered cooperative communication network (WPCCN), which includes a hybrid access point (HAP), a source and a relay. The considered source and relay are installed without embedded energy supply (EES), thus are dependent on energy harvested from signals from the HAP to power their cooperative information transmission (IT). Taking inspiration from this, the author group investigates into a harvest-then-cooperate (HTC) protocol, whereas the source and the relay first harvest the energy from the AP in a downlink (DL) and then collaboratively work in uplink (UL) for IT of the source. For careful evaluation of the system performance, derivations of the approximate closed-form expression of the outage probability (OP) and an average bit error probability ( ABER) for the HTC protocol over Rayleigh fading channels are done. Lastly, the author group performs Monte-Carlo simulations to reassure the numerical results they obtained.Web of Science255746

A SURVEY OF STUDENTS’ ABILITY OF IDENTIFYING ERRORS IN WRONG SOLUTIONS FOR THE MATHEMATICAL PROBLEMS RELATED TO THE MONOTONICITY OF FUNCTIONS

The monotonicity of a function plays an important role in the general mathematics curriculum in Vietnam, because it is considered as an effective tool for solving mathematical problems involved with the monotonic intervals of functions, their extreme, absolute maximum value and absolute minimum value. Normally, students commit errors in solving these problems because of their complexity and difficulty. In addition, specific characteristics of knowledge also make children make mistakes. The sample consisted of 362 students, and they had the task of identifying errors in false assumptions. From the results of the survey, it was found that when dealing with the monotonicity of the functions, students were still misled.  Article visualizations

ResCap: Residual Capsules Network for Medical Image Segmentation

Convolutional neural networks (CNNs) have shown remarkable results for a wide range of task in computer vision. However, CNNs has the limitation of poor translation invariance and lack of information about pose; thus, it requires a lot of data. Capsule networks, however, have the ability to preserve information about the pose. In this paper, we present a capsule-based network for medical image segmentation. We adopt the contracting path of the U-Net architecture. The network achieves the same accuracy as U-Net but is much smaller (0.16% number of parameters compared with U-Net)

Camellia sinensis extract delays microbiological and oxidative changes in striped catfish fillets during frozen storage

peer reviewedThis study investigated the effects of tea leaf (Camellia sinensis) extract on the quality of striped catfish (Pangasianodon hypophthalmus) fillets during 18-months of frozen storage (-20 ± 2 °C). Fillet samples were submitted to the treatments Control (cold tap water), CS 7.63 (C. sinensis extract solution 7.63 µg/mL) and CS 625 (C. sinensis extract 625 µg/mL) and stored for 18 months, with collections performed at 0, 1, 3, 6, 9, 12 and 18 months. Total viable count, physicochemical parameters (water holding capacity, total volatile basic nitrogen, peroxide value, thiobarbituric acid reactive substances, moisture and pH), sensory properties and color measurement were evaluated. Results showed that fillets treated with C.a sinensis extracts slightly reduced lipid oxidation, inhibited bacterial growth and improved sensory properties compared to untreated samples, without causing significant changes in the other quality indicators. The findings indicated that the green tea leaf extract immersion treatments, contributed to the improved quality preservation of striped catfish fillets during frozen storage
