Work intensity and individual well-being: Evidence from Thailand
Creators: name: Pichetpongsa, Anant
Publisher: name: ProQuest
Year: 2023
Subjects: classificationCode: 38
subject: Economics

description: This research examines the measurement of individual well-being based not only on money income, but also those aspects of individual capabilities and functioning that are not acquired through the market nor solely the result of market participation. This research focuses especially on the incidence of work intensity aspect (based on time use information), which is believed to convey an important qualitative dimension of individual well-being that the conventional measures do not. Specifically, individual well-being is determined by three main components---personal income, educational attainment, and work intensity. An individual-level survey of urban poor home-based workers in Bangkok, Thailand collected in 2002 is used to develop the well-being index. The survey shows that there are significant differences in well-being between men and women workers. Women respondents are worse off in all respects of quality of life---money, education, and time. The empirical tests of the well-being component index and subjective well-being show that the inverse work intensity index is a good predictor of individuals, subjective well-being. It also solves the puzzle that income alone cannot significantly explain individuals' perspective of their well-being. Income only brought happiness to individuals if they did not have to work incredibly long hours to earn it. The empirical study of subjective well-being and well-being index components also suggests that economic policies and development strategies that tend to increase low-wage jobs, e.g., low-wage export oriented development, will not raise the well-being of individuals, specifically poor workers Finally, the empirical results indicate that the traditional methods of measuring well-being that do not take into account time use information tend to omit crucial well-being information, and are likely to give an incomplete picture.

description: A study was conducted for a period of 45 days to evaluate the efficiency of egg custard in substituting Atemia nauplii for post larvae production of giant fresh water prawn, Macrobrachium rosenbergii. Three Treatments were designed for feeding with three replications as follows: (i) Treatment Ti, alternate diet (1st 10 days only Artemia then only egg custard), (ii) Treatment T2, combined feed (Artemia and egg custard) and (iii) Treatment T3, egg custard. Stocking density of larvae was 50/liter. Larvae cultured on combined diets had the highest ( P<0.05) mean production rate 26.07±1.13 /I with a corresponding survival of 52.13±2.14%. The post larval yield for the group of larvae fed egg custard alone was nil. This result indicate that rearing of M. rosenbergii larvae using only custard is not possible. During the feeding of combination diet it was observed that larvae were not fed artificial feed before 7 days of rearing Period, artificial feed. The survival rate of larvae fed alternate diet (7.27±0.08%) was significantly lower (P<0.05) than the survival rate of larvae fed combined diet (52.13±2.14%). It indicate that egg custard alone (after 10 days) might not be adequate diet as Artemia for higher production of M. rosenbergii post larvae. It is concluded from the present study that combined diet (Artemia and custard) can be used for larvae rearing of M. rosenbergli and custard can be used after 10 days of rearing period with Artemia.
Quantifying the evolution of copyright and trademark law

Publisher: name: American University
Year: 2023

description: This research compiles two time series, cross-sectional indices of the relative strengths of copyright and trademark laws around the world from 1965 until 2002. This study is motivated by the need to understand the effects of different strength copyright and trademark laws in an era when their very composition is being questioned. The first section examines methodologies used in large-scale indices as well as previous copyright and trademark indices. Sections two and three use national laws to develop separate indices for trademark and copyright, respectively. The final section examines the relationship among the strength of copyright protection and creative output, as measured by films submitted to the Cannes Film Festival. The empirical study finds a statistically significant positive relationship between film production and overall copyright strength in an economy. However, the research also finds there is no statistically significant relationship between the duration of film protection and film output.

description: Understanding the dynamics of Fourier domain mode-locked (FDML) lasers is crucial for determining physical coherence limits, and for finding new superior methods for experimental realization. In addition, the rich interplay of linear and nonlinear effects in a laser ring system is of great theoretical interest. Here we investigate the dynamics of a highly dispersion-compensated setup, where over a bandwidth of more than 100 nm, a highly coherent output with nearly shot-noise-limited intensity fluctuations was experimentally demonstrated. This output is called the sweet-spot. We show by numerical simulation that a finite amount of residual dispersion in the fiber delay cavity of FDML lasers can be compensated by the group delay dispersion in the swept bandpass filter, such that the intensity trace exhibits no dips or high-frequency distortions, which are the main source of noise in the laser. In the same way, a small detuning from the ideal sweep filter frequency can be tolerated. Furthermore, we find that the filter's group delay dispersion improves the coherence properties of the laser, and acts as a self-stabilizing element in the cavity. Our theoretical model is validated against experimental data, showing that all relevant physical effects for the sweet-spot operating regime are included.

description: A study on the taxonomic comparison of five populations of the climbing perch, koi, Anabas testudineus was conducted from five regions of Bangladesh viz. Chittagong, Dhaka, Khulna, Rajshahi and Sylhet. The comparison was based on the morphometric and meristic data of the populations collected over a period of 4 months from July to October 2003. The average total length, standard length, post orbital length, eye diameter, length of base of the dorsal and anal fin of the population of Khulna region were higher than those of the other four populations. All the population characteristics of Chittagong region revealed significant difference (P<0.05) than those in Khulna. Average meristic characters showed no difference (P>0.05) in all five populations in dorsal fin rays, pelvic fin rays, anal fin rays, and number of scale below and above lateral line. However, number of dorsal spine was found to be significantly higher (P<0.05) in Dhaka region than those in other regions. Number of caudal fin rays was also higher in Dhaka region. Five different body proportions viz., Standard Length: Head Length; Standard Length: Body Depth; Head Length: Eye Diameter; Head Length: Pre-orbital; and Head Length: Post orbital were recorded and significant differences at 5% level were obtained.

description: Using a panel data set of 445 small-scale cattle farm households in northern Togo, this paper examines the impact of disease control interventions on cattle productivity, household welfare, poverty and vulnerability. We employ difference in difference analysis to examine the impact on livestock productivity, consumption per capita and stochastic poverty and vulnerability to future poverty. We find a positive impact on improving cattle productivity, income and consumption per capita. Our results also show positive poverty reduction effects of the interventions as well as a reduction in vulnerability to poverty. We can show that the interventions have positive smoothening effects on household consumption and income. Our results are robust across different estimation specifications such as fixed effects and instrumental variable fixed effects models.

description: Given a group $G$, we write $x^G$ for the conjugacy class of $G$ containing the element $x$. A famous theorem of B. H. Neumann states that if $G$ is a group in which all conjugacy classes are finite with bounded size, then the derived group $G'$ is finite. We establish the following result. Let $n$ be a positive integer and $K$ a subgroup of a group $G$ such that $|x^G|\leq n$ for each $x\in K$. Let $H=\langle K^G\rangle$ be the normal closure of $K$. Then the order of the derived group $H'$ is finite and $n$-bounded. Some corollaries of this result are also discussed.

description: Return migration is an important part of rural labor mobility in China, and has been given growing concern recently by governments. However, research covering the duration of stay in their home county, a basic question of labor mobility and a precondition for policy making, is far from enough. The aim of this paper is to analyze the period of return for these migrants based on employment history data among rural laborers. The data was collected from a random, nationally representative sample of 100 rural villages in five provinces of China. We find that 22.3 percent of migrants returned from 1998 to 2015, and most returning migrants stay for a long time. Using the OLS, Tobit, and Heckman two-step methods, the results show that returning migrants who are old, more educated, unmarried, and with school-age children are more likely to stay longer in their home county. From a development perspective, returning migrants are expected to play an important role in the process of rural revitalization. Most importantly, the government should still gradually eliminate institutional limitations facing rural people and promote the free flow of labor resources in the process of realizing the integration of urban and rural areas.

Haldane Insulator in the 1D Nearest-Neighbor Extended Bose-Hubbard Model with Cavity-Mediated Long-Range Interactions

description: In the one-dimensional Bose-Hubbard model with on-site and nearest neighbor interactions, a gapped phase characterized by an exotic non-local order parameter emerges, the Haldane insulator. Bose-Hubbard models with cavity-mediated global range interactions display phase diagrams, which are very similar to those with nearest neighbor repulsive interactions, but the Haldane phase remains elusive there. Here we study the one-dimensional Bose-Hubbard model with nearest-neighbor and cavity-mediated global-range interactions and scrutinize the existence of a Haldane Insulator phase. With the help of extensive quantum Monte-Carlo simulations we find that in the Bose-Hubbard model with only cavity-mediated global-range interactions no Haldane phase exists. For a combination of both interactions, the Haldane Insulator phase shrinks rapidly with increasing strength of the cavity-mediated global-range interactions. Thus, in spite of the otherwise very similar behavior the mean-field like cavity-mediated interactions strongly suppress the non-local order favored by nearest neighbor repulsion in some regions of the phase diagram.

description: This dissertation explores the relationship between women's political rights and their role in the economic development process in the United Arab Emirates (UAE) from 1982 to 2002. While women are integrated in the public life as workers, they have limited access to the top positions in the government hierarchy and are completely denied political rights. Specifically, this study (1) examines the ways in which the structured cultural factors, such as religion, traditions, customs, and constitutional laws influence the nature and practice of political life for women, (2) addresses how aspects of gender, tribal identity, and neopatriarchy are articulated in UAE society, as well as how they impact social change and the development of women in the public life, and (3) presents how culture, economy, and politics affect each other, as they are eternally joined and cannot be separated. To expose the existing reality of women's lives in the UAE, this research is guided by a theoretical framework that includes development theories, such as modernization, dependency and neopatriarchy as well as feminist theories. Women's experiences of everyday life in the UAE are the source of investigation, in that the study draws upon 65 face-to-face interviews, 35 focus groups, field observations, and informal discussions that emerged from five months of fieldwork throughout the seven Emirates. To gain a specific understanding of women's economic and political position, the research utilizes statistical evidence from the government archive. The findings of this research can be summarized in the following five declarations: First, women's achievement in the labor force does not push them toward politics. Second, because of oil wealth and modernization, culture is impacted by external aspects to create neopatriarchy. Third, this neopatriarchy sets up barriers for women in politics that are not in the labor force. Fourth, women in the UAE wish to take part in politics, but only through their social groups. This dissertation asserts that in order for any advancement to take place, women need to empower themselves from within, as a collective movement and as individuals, as well as recognize their potential as a social, economic, and political power.

description: We investigate the influence of magnons on the temperature-dependence and the anisotropy of the spin-orbit torque (SOT). For this purpose we use 3rd order perturbation theory in the framework of the Keldysh formalism in order to derive suitable equations to compute the magnonic SOT. We find several contributions to the magnonic SOT, which depend differently on the spin-wave stiffness $\mathcal{A}$ and on the temperature $T$, with the dominating contribution scaling like $T^{2}/\mathcal{A}^{2}$. Based on this formalism we compute the magnonic SOT in the ferromagnetic Rashba model. For large Rashba parameters the magnonic SOT is strongly anisotropic and for small quasiparticle broadening it may become larger than the non-magnonic SOT.

description: We develop a theoretical framework to analyse economically optimal GHG abatement strategies for a mixed farming system with crop and dairy production. Subsequently, it is implemented as a detailed bio-economic optimization model for mixed arable-dairy farms with non-linear crop and milk yield functions and a detailed accounting of Green House Gas emissions, and parameterized to Finnish agricultural and environmental conditions. Focusing on the role of sunk costs of investments and opportunity costs of labour, we analyse optimal farm management decisions under different CO2 tax levels, considering adjustments at the extensive and intensive margin, including changes in manure storage systems and application methods. We find that the amount of GHG abatement responds more strongly to the level of sunk and opportunity costs than the CO2 tax level which underlines the relevance of the planning horizon for that type of analysis. Our findings reveal that low cost abatement options in dairy production are limited. Our model can be easily adjusted to other locations, market and policy conditions and thus provides an interesting starting point for international comparisons. Acknowledgement :

description: We demonstrate saturated internal detection efficiency at 1550 nm wavelengths for meander-shaped superconducting nanowire single-photon detectors made of 3 nm thick MoSi films with widths of 1 and 3 $μm$, and active areas up to 400 by 400 $μm^2$. Despite hairpin turns and a large number of squares (up to $10^4$) in the device, the dark count rate was measured to be ~10$^3$ cps at 99% of the switching current. This value is about two orders of magnitude lower than results reported recently for short MoSi devices with shunt resistors. We also found that 5 nm thick MoSi detectors with the same geometry were insensitive to single near-infrared photons, which may be associated with different levels of suppression of the superconducting order parameter. However, our results obtained on 3 nm thick MoSi devices are in a good agreement with predictions in the frame of a kinetic-equation approach.

title: The relationship between malaria and haemoglobin E in southern Vietnam
Creators: name: O'Riordan, Sean
Publisher: name: The Open University
Year: 2008

description: Haemoglobin E is the most common single mutation haemoglobinopathy worldwide, presumably due to selective pressure from malaria. There is no good clinical data to support this hypothesis, however, and the laboratory data is conflicting. This thesis presents the results of prevalence studies, cross sectional association studies and a case control study undertaken to examine the relationship between haemoglobin E and malaria in southern Vietnam. The S’Tieng ethnic group demonstrated a high prevalence of HbE and alpha thalassaemia, whilst the majority Kinh, and minorities from the north of Vietnam, had a low prevalence. The S’Tieng also appeared to experience a higher burden of malaria infection, as determined by malaria parasite point prevalence and the age pattern of severe disease. There was no association between haemoglobin E and malaria in the cross sectional surveys once correction was made for ethnicity. A knowledge, attitudes and practice survey demonstrated a small difference in the proportion of S’Tilng using bednets compared to other ethnic groups, but no other significant differences to account for their higher malaria burden. Malaria control programmes, which had been very successful elsewhere in Vietnam, have seemed slow to take effect in the central and southern highlands, particularly amongst ethnic minority groups. There appeared to be some success over the course of the study, however, with the result that recruitment to the case control study of severe malaria was slow, and there were insufficient cases from populations with high prevalences of haemoglobin E to draw any firm conclusions. The data gathered demonstrate a trend towards susceptibility to moderate and severe disease considered together, however, suggesting that any protective effect is likely to be modest.

description: In this paper, we examine factors influencing adoption of the index-based livestock insurance (IBLI) in Kwara State, Nigeria. We apply open-ended contingent valuation technique to determine the amount farmers are willing to pay for the IBLI offering coverage for livestock valued at N500,000 (Nigerian Naira). We carried out this study on household heads who took the traditional insurance in previous years. We also discuss important issues ranging from the IBLI premium cost to the effect of religion, education and gender on adoption of the insurance product. Our results create an initial framework for the acceptance of the IBLI since the product is not presently existing in Nigeria.

description: This study presents the results of the search for Leo Baeck’s private library that was looted by the Nazis in 1943. It shows that the current state of research is failing to provide methods to conduct this search, and demonstrates how to overcome this lack by adopting a bibliometric approach to provenance research. To allow a title-based search for the books once owned by Leo Baeck, the catalog of the lost collection is reconstructed. While the study addresses mainly the methodology of searching for looted books, it also demonstrates how the instruments designed to help locating and identifying the looted books can be used to describe the lost collection. Based on the reconstructed catalog the collection is described and the role of usage frequency for a private collector is discussed. Furthermore, the ownership marks found inside the resurfaced items are used to map the dispersion of Baeck’s books following their theft.

Primordial flat frame -- a new view on inflation

description: Models of inflationary cosmology admit a choice of the metric for which the geometry of homogeneous isotropic solutions becomes flat Minkowski space in the infinite past. In this primordial flat frame all mass scales vanish in the infinite past and quantum scale symmetry is realized. The cosmological evolution is dominantly described by the slow increase of a scalar field which sets the scale of all masses. We construct the primordial flat frame for standard models of inflation as Starobinsky inflation or chaotic inflation. In particular, we discuss the evolution of inhomogeneous solutions in the neighborhood of the homogeneous isotropic background solution and their relation to the observable primordial fluctuation spectrum. If the propagators for the graviton and scalar field remain regular, our observed inhomogeneous Universe can be extrapolated back to the infinite past in physical time. In this case there is no physical big-bang singularity -- the latter reflects only a singular choice of ``field coordinates". Independently of the issue of singularity the primordial flat frame offers a new view on the physical properties of the inflationary universe, which can be characterized as a very slowly evolving almost empty vacuum state with approximate scale symmetry.

description: The present study shows a methodology analysing the role plaid by information in conditioning the criteria used to schedule irrigation by farmers. The method is applied to the problem of comparing advanced instruments (advice services) and prevailing current practices (calendar irrigation) in valuing and predicting soil water content to schedule irrigation. Such assessment approach brought to the formulation of two main hypotheses: a) the message service is valuable if those messages with higher failure consequences are enough accurate to drive decisions; b) The use of information services to plan irrigation is favoured by the increasing frequencies of irrigation intervention because of the relatively lower expected consequences of failing to meet predictions. This methodology was applied to few pilot experiments. Observed impacts substantiate model hypothesis, revealing that the introduction of advanced information systems is favoured in sub-arid climate regions and for drip irrigated crops, where it was recorded a 0% to 20% increase in gross margin and a 10% to 30% water saving. The study concludes addressing the condition justifying the use of advanced information systems to schedule irrigation intervention and offering some policy recommendation to drive the development and the early adoption of such technologies .

Quantum Dark Soliton: Non-Perturbative Diffusion of Phase and Position

description: The dark soliton solution of the Gross-Pitaevskii equation in one dimension has two parameters that do not change the energy of the solution: the global phase of the condensate wave function and the position of the soliton. These degeneracies appear in the Bogoliubov theory as Bogoliubov modes with zero frequencies and zero norms. These ``zero modes'' cannot be quantized as the usual Bogoliubov quasiparticle harmonic oscillators. They must be treated in a non-perturbative way. In this paper I develop non-perturbative theory of zero modes. This theory provides non-perturbative description of quantum phase diffusion and quantum diffusion of soliton position. An initially well localized wave packet for soliton position is predicted to disperse beyond the width of the soliton.

description: The project aims to develop methods for the synthesis of arrays of silica nanochannels with disc-shaped morphology and tunable pore size. These so-called Molecular Alignment Chips (MACs) are promising host materials for the supramolecular organization of guests. The project investigates several applications of MACs with a focus on light-harvesting systems such as luminescent solar concentrators (LSCs). The fundamental project objectives concern the synthesis of MACs with well-defined particle morphology and tunable nanochannel diameter. Host materials of this kind provide a platform for the alignment of any desired guest species. In the field of LSCs, this ultimately opens possibilities for increasing the trapping efficiency and for reducing self-absorption losses.
Variable stars in the globular cluster NGC 3201. I. Multimode SX Phe-type variables

description: We report on the discovery of eleven multimode SX Phoenicis--type blue stragglers in the field of the southern globular cluster NGC 3201. In these variables both radial and non-radial modes are excited. For three variables the derived period ratio is close to that observed in SX Phoenicis itself, suggesting that these stars are pulsating in the fundamental and the first-overtone radial modes. Using the McNamara (1997) period-luminosity relation we have estimated the apparent distance modulus to NGC 3201 to be 14.08$\pm0.06\pm0.1$mag.

description: Watershed development helps reduce farmers vulnerability to droughts and increase their incomes by rehabilitating the productive capacity of the land through water and soil conservation techniques. We estimate the impact of India s largest watershed development program called Integrated Watershed Management Program (IWMP) in four of the most drought affected districts of Maharashtra, India. We collected data from a random sample of 800 farmers in the four districts. Watershed programs may not show any impact on crop area or yields in years of normal of high rainfall. We, therefore, collected recall data on cropped area and yields for the last 4 years from our respondents. Our analysis shows that cotton yields were 11-32 percent higher and soybean yields were 12-25% higher for farmers whose land received watershed treatment. Four years recall data on crop area and yield, also allows us to look at the effect of IWMP on resilience of agriculture to droughts. We find that drought led to 30-40% yield loss in soybean and cotton compared to the yield in a normal year. However, watershed treatment reduced the yield loss due to drought by more than 30 percent.

description: Federated learning (FL) is a novel machine learning setting that enables on-device intelligence via decentralized training and federated optimization. Deep neural networks' rapid development facilitates the learning techniques for modeling complex problems and emerges into federated deep learning under the federated setting. However, the tremendous amount of model parameters burdens the communication network with a high load of transportation. This paper introduces two approaches for improving communication efficiency by dynamic sampling and top-$k$ selective masking. The former controls the fraction of selected client models dynamically, while the latter selects parameters with top-$k$ largest values of difference for federated updating. Experiments on convolutional image classification and recurrent language modeling are conducted on three public datasets to show our proposed methods' effectiveness.

description: Ultrahigh energy neutrinos can provide important information about the distant astronomical objects and the origin of the Universe. Precise knowledge about their interactions and production rates is essential for estimating background, expected fluxes and detection probabilities. In this paper we review the applications of the high energy QCD to the calculations of the interaction cross sections of the neutrinos. We also study the production of the ultrahigh energy neutrinos in the atmosphere due to the charm and beauty decays.

description: Combining dispersion measures, distances and emission measures for 157 pulsars lying above \mid b \mid > 5 degree and between 60 degree < l < 360 degree we find the mean volume filling factor (\bar{f_v}) of the diffused ionized gas in the Milky Way. This filling factor is inversely related to the mean electron density (\bar{n_c}) in the clouds, \bar{f_v} = (0.0184 +/- 0.0014) \bar{n_c}^{-1.07 +/- 0.03}, implying a nearly constant average electron density distribution within 3 kpc of the sun.
