Ageing and poverty in africa and the role of social pensions
No full textIn many low income African countries, three factors are placing an undue burden on the elderly. First, the burden on the elderly has enormously increased with the increase in mortality of prime age adults due to HIV AIDS pandemic and regional conflicts. Second, the traditional safety net of the extended family has become ineffective and unreliable for the elderly. Third, in a few countries, the elderly are called upon to shoulder the responsibility of the family as they became the principal breadwinners and caregivers for young children. While a number of studies have examined the welfare consequences of these developments on children, few studies have systematically analyzed the poverty situation among the elderly (relative to other groups) in low income countries Africa, and the role of social pensions. This study aims to fill this gap.Ageing, Poverty, Social Pensions, Developing Countries, Africa
The impact of two tier producer and consumer food pricing in India
No full textIndia's government procures agricultural products such as rice, wheat, and sugar at below-market prices and sells them in both urban and rural ration shops. The rest of such crops is sold in the open market. This creates a two-tier price system for consumers and producers. Many (including Dantwala, Mellor, and Hayami, Subbarao, and Otsuka) claim that such a policy raises the open-market price so much that it ultimately increases the average price received by farmers. Iftrue, the gainers would be the farm sector as a whole and low-income urban consumers with access to the ration shops. Losers would be the high-income urban consumers who buy at the open-market price. This view has provided an intellectual basis for the policy. The author examines a variety of cases: with and without rationing, with rationing by ration cards or by queuing, with and without the urban rich having access to the ration shops, with and without free trade, and with a marketable surplus with positive, negative, or zero price elasticity. He finds that in most cases the policy's impact on the average price is either negative or ambiguous, and it is negative in the more realistic cases. A negative impact implies that farmers on the whole lose from the procurement policy. But small farmers who are net buyers of the procured crops, and landless laborers, gain from a lower average price in the short run (especially if they have easy access to the rural ration shops). The long-run effect depends on the impact of the lower average price on rural employment and wages.Markets and Market Access,Economic Theory&Research,Environmental Economics&Policies,Consumption,Access to Markets
Robust statistics over Riemannian manifolds for computer vision
No full textThe nonlinear nature of many compute vision tasks involves analysis over curved nonlinear spaces embedded in higher dimensional Euclidean spaces. Such spaces are known as manifolds and can be studied using the theory of differential geometry. In this thesis we develop two algorithms which can be applied over manifolds.
The nonlinear mean shift algorithm is a generalization of the original mean shift, a popular feature space analysis method for vector spaces. Nonlinear mean shift can be applied to any Riemannian manifold and is provably convergent to the local maxima of an appropriate kernel density. This algorithm is used for motion segmentation with different motion models and for the filtering of complex image data.
The projection based M-estimator is a robust regression algorithm which does not require a user supplied estimate of the scale, the level of noise corrupting the inliers. We build on the connections between kernel density estimation and robust M-estimators and develop data driven rules for scale estimation. The method can be generalized to handle heteroscedastic data and subspace estimation. The results of using pbM for affine motion estimation, fundamental matrix estimation and multibody factorization are presented.
A new sensor fusion method which can handle heteroscedastic data and incomplete estimates of parameters is also discussed. The method is used to combine image based pose estimates with inertial sensors.Ph.D.Includes bibliographical references (p. 137-144)
On a Result of Smith and Subbarao Concerning a Divisor Problem
No full textAbstractLet d(n;l,k) denote the number of divisors of the positive integer n which are congruent to I modulo k. The objective of the present paper is to prove that (for some exponent θ<⅓)holds uniformly in l, k and x satisfying 1≤l≤k≤x. This improves a recent result due to R. A. Smith and M. V. Subbarao [3].</jats:p
Assessing Stress Levels and Influencing Factors for Faculty in Higher Education Institutions: A Case Study in Visakhapatnam of Andhra Pradesh
No full textStress is common among faculty during their college work. They can often experience high levels of stress because they frequently encounter various challenges at their workplace that can negatively affect their academic performance and general health. However, familiar sources of stress among faculty working in higher education sectors have not been clearly defined. Therefore, this study aimed to determine the familiar sources of stress among them in the region of Visakhapatnam. One of the northeastern coastal districts of Andhra Pradesh belongs to south India. This was a descriptive, cross-sectional study. The convenience sample included 85 faculties working in various higher education colleges in Visakhapatnam. The Faculty Stress Index (FSI) was used to describe the sources of stress from four domains: academic load, financial concerns, personal problems, and interface worries. The majority (60%) of the participants were aged between 31 and 60. The primary source of stress was academic load and interface teaching and research responsibilities (M = 3.74, SD = 1.156), followed by financial worries (M = 3.73, SD = 1.285), lack of appreciation regarding their contributions (M =3.61, SD = 1.319), and personal problems to excel in teaching evaluations (M = 2.75, SD = 1.272). The faculty’s stress resulting from their academic load was higher than the other sources of stress, and it was related to a large number of materials like targeted assignments, extended working hours, or other research-related works required for faculty. It is suggested to create a positive and supportive work environment at the workplace, implement strategies for workload management, and professional development opportunities.Published By: Blue Eyes Intelligence Engineering and Sciences Publication (BEIESP)

How to make public works work : a review of the experiences
No full textThis paper reviews the experience with public works programs (PWPs) in several countries over the past 20 years to delineate use patterns and to determine the factors contributing to its use as a successful safety net program. The analysis shows that PWP have been used extensively in response to either a one-time large covariate shock, or repeated shocks. In low income countries, PWPs also have an antipoverty or poverty reduction objective. Our review shows that well designed and implemented PWPs can help mitigating income shocks; the program can also be used as an effective anti-poverty instrument. The paper examines the factors behind the observed wide variation in the effectiveness of the program in accomplishing its goals and identifies prerequisites for making PWPs successful safety net interventions capable of protecting the poor from income shocks, thus reducing both temporal and seasonal poverty, while creating useful public goods or services for the communities. For public works programs to be successful, it is important firstly to: a) have clear objectives; b) select projects that can create valuable public goods; and c) ensure predictable funding. Secondly, the success of the program depends critically on careful design and incorporation of all the key design features. Finally, a credible monitoring and evaluation system designed right upfront, prior to launching of theprogram can allow for mid course corrections and to respond to sudden changes which can inhibit effective implementation. The potential of the PWP program is enormous both in countries that have experiences with these programs and especially in countries that never used them. However, more research is needed investigation is needed to better understand the impact of PWPs, such as second round effects from the created assets, the impacts on the labor market, and their cost-effectiveness after factoring in both the immediate and second round benefits from its program.Safety Nets and Transfers,Rural Poverty Reduction,Labor Markets,Labor Policies,Public Sector Economics
