Enhancing public health practice through a capacity-building educational programme:an evaluation

BACKGROUND: The Post-Graduate Diploma in Public Health Management, launched by the Govt. of India under the aegis of the National Rural Health Mission in 2008, aims to enhance the managerial capabilities of public health professionals to improve the public health system. The Govt. of India invested enormous resources into this programme and requested an evaluation to understand the current processes, assess the graduates’ work performance and identify areas for improvement. METHODS: Quantitative telephone surveys as well as qualitative in-depth interviews were used. Graduates from the first three batches, their supervisors, peers and subordinates and faculty members were interviewed. Quantitative data were analysed using proportions, means and interpretative descriptions. Qualitative analyses involved transcription, translation, sorting, coding and filing into domains. RESULTS: Of the 363 graduates whose contact details were available, 138 could not be contacted. Two hundred twenty-three (223) graduates (61.43% of eligible participants) were interviewed by telephone; 52 in-depth interviews were conducted. Of the graduates who joined, 63.8% graduates were motivated to join the programme for career advancement and gaining public health knowledge. The content was theoretically good, informative and well-designed. Graduates expressed need for more practical and group work. After graduating, they reported being equipped with some new skills to implement programmes effectively. They reported that attitudes and healthcare delivery practices had improved; they had better self-esteem, increased confidence, better communication skills and implementation capacity. While they were able to apply some skills, they encountered some barriers, such as governance, placements, lack of support from the system and community, inadequate implementation authority and lack of planning by the state government. Incentives (both monetary and non-monetary) played a major role in motivating them to deliver public health services. They suggested that states should nominate candidates expected to make a significant contribution to the health system, recognition from a relevant authoritative national body and need for a placement cell, especially for the self-sponsored candidates. CONCLUSIONS: A continuous mechanism for interaction and dialogue with the graduates during and after completion of the programme should be designed. This evaluation helped by providing inputs for refining the programme

Unconventional Low-Cost Fabrication and Patterning Techniques for Point of Care Diagnostics

The potential of rapid, quantitative, and sensitive diagnosis has led to many innovative ‘lab on chip’ technologies for point of care diagnostic applications. Because these chips must be designed within strict cost constraints to be widely deployable, recent research in this area has produced extremely novel non-conventional micro- and nano-fabrication innovations. These advances can be leveraged for other biological assays as well, including for custom assay development and academic prototyping. The technologies reviewed here leverage extremely low-cost substrates and easily adoptable ways to pattern both structural and biological materials at high resolution in unprecedented ways. These new approaches offer the promise of more rapid prototyping with less investment in capital equipment as well as greater flexibility in design. Though still in their infancy, these technologies hold potential to improve upon the resolution, sensitivity, flexibility, and cost-savings over more traditional approaches

This Paper is dedicated to the Memory

In this article, the author argues that comparative tax law has an intellectual history. More specifically, the author claims that history reveals there is a distinguishable comparative tax law scholarship where tax scholars engage in common debates. The author then offers a description of method, highlighting the difficulty of identifying the work that might be considered “comparative tax law.” Next, the author conceptualizes and clusters contributions from scholars who have framed the comparative tax law field. The author argues that our national boundedness, combined with the lack of an explicit network of scholars, has masked the rich intellectual history in the field of comparative tax law. Finally, the author concludes by drawing attention to the network effects that seem to inform some of the approaches taken by the key contributors to comparative tax law’s intellectual histor

Hydrologic Evaluation of the TMPA-3B42V7 Precipitation Data Set over an Agricultural Watershed Using the SWAT Model

Real-time availability of satellite-based precipitation products gives the hydrologic prediction community an opportunity to enhance hydrologic prediction for a watershed or river basin. In the present study, the latest tropical rainfall-measuring mission (TRMM) multisatellite precipitation analysis (TMPA) research product, 3B42V7, was assessed against a gauge-based Indian Meteorological Department (IMD) gauge-based gridded data set using statistical and contingency table methods for an agricultural watershed in India. A comparative analysis of the TRMM and IMD data sets was carried out on daily, monthly, seasonal, and yearly bases for 16years (1998-2013). The analysis revealed that the TRMM data set performed reasonably well but showed significant biases. Although it underestimated watershed-averaged daily precipitation (bias=-28.65%, correlation coefficient=0.42), its results improved for monthly precipitation (bias=-26.17%, correlation coefficient=0.86). Moreover, its rainfall detection capability was determined to be better during the monsoon season than during the nonmonsoon season. In all timescales, however, it usually underestimated heavy rains. The utility of the TRMM precipitation data set in hydrologic modeling was evaluated via the semidistributed soil and water assessment tool (SWAT) hydrologic model. Using the IMD gauged data-calibrated SWAT model, TRMM data set-based simulation showed limited hydrologic prediction on a daily scale, whereas its prediction capability was fairly good on a monthly scale. The SWAT model exhibited remarkable improvement in both daily and monthly simulation when recalibrated with TRMM precipitation data. However, when driven by IMD data, the model always performed better than its TRMM-driven counterpart. The analysis indicated that the use of the TRMM precipitation data set can be a compensating approach after suitable bias correction and that it has the potential for hydrologic prediction in data-sparse regions

Structural, dielectric relaxation and piezoelectric characterization of Sr2+ substituted modified PMS-PZT ceramic

Pyrochlore phase free [Pb0.94Sr0.06] [(Mn1/3Sb2/3)(0.05)(Zr0.53Ti0.47)(0.95)] O-3 ceramics has been synthesized with pure Perovskite phase by semi-wet route using the columbite precursor method. The field dependences of the dielectric response and the conductivity have been measured in a frequency range from 50 Hz to 1 MHz and in a temperature range from 303 K to 773 K. An analysis of the real and imaginary parts of the dielectric permittivity with frequency has been performed, assuming a distribution of relaxation times. The scaling behavior of the dielectric loss spectra suggests that the distribution of the relaxation times is temperature independent. The SEM photographs of the sintered specimens present the homogenous structures and well-grown grains with a sharp grain boundary. The material exhibits tetragonal structure. When measured at frequency (100 Hz), the polarization shows a strong field dependence. Different piezoelectric figures of merit (k(p), d(33) and Q(m)) of the material have also been measured obtaining their values as 0.53, 271 pC/N and 1115, respectively, which are even higher than those of pure PZT with morphotropic phase boundary (MPB) composition. Thus the present ceramics have the optimal overall performance and are promising candidates for the various high power piezoelectric applications. (C) 2011 Elsevier B.V. All rights reserved

Dielectric relaxation, phase transition and Rietveld studies of perovskite Pb0.94Sr0.06](Mn1/3Sb2/3)(0.05)(Zr0.52Ti0.48)(0.95)]O-3 ceramics

The frequency-dependent dielectric relaxation of Pb0.94Sr0.06](Mn1/3Sb2/3)(0.05)(Zr0.52Ti0.48)(0.95)]O-3 ceramics, synthesized in pure perovskite phase by a solid-state reaction technique is investigated in the temperature range from 303 to 773 K by alternating-current impedance spectroscopy. Using Cole-Cole model, an analysis of the imaginary part of the dielectric permittivity with frequency is performed assuming a distribution of relaxation times. The scaling behavior of the imaginary part of the electric modulus suggests that the relaxation describes the same mechanism at various temperatures. The variation of dielectric constant with temperature is explained considering the space-charge polarization. The SEM indicates that the sample has single phase with an average grain size similar to 14.2 mu m. The material exhibits tetragonal structure. A detailed temperature dependent dielectric study at various frequencies has also been performed. (C) 2013 Elsevier B.V. All rights reserved

Technological advancements in jaggery-making processes and emission reduction potential via clean combustion for sustainable jaggery production: An overview

Jaggery is a kind of unrefined non-centrifugal sugar (NCS) used mainly in Asia, Africa, Latin America, and the Caribbean. Traditionally, jaggery is produced by concentrating sugarcane juice in open pans with the help of bagasse combustion. However, due to thermal energy loss with flue gases and an unscientific approach in plant construction, jaggery plants have a poor thermal efficiency of less than 25%, poor emission characteristics, and a high bagasse consumption rate. Advanced jaggery-making techniques use solar energy and heat pumps for jaggery production. However, these techniques are in the early stage of development, and the literature indicates that these techniques should be used in conjuction with traditional ones to improve the performance of jaggery making plants. This literature review describes advances in jaggery-making methods, critically analyzed them, and provides a qualitative comparison of these methods. Further, gaps in the existing literature are identified and reported for future research direction. In addition, efforts have been made to quantify and estimate the emissions reduction and bagasse consumption potentials from the traditional jaggery industry to make this rural industry a sustainable and profitable business for rural entrepreneurs. The comparison with the recently developed clean combustion device exhibits that the harmful emissions from the jaggery industry could be reduced drastically viz. 95%–98% of PM2.5; 92%–95% of CO, and 52–60% of CO2, while saving more than 35% of bagasse consumption. Implemented at a national scale, it may reduce nearly 3% of all harmful emissions in the country, which is equally applicable elsewhere
