    The spatio-temporal evolution of nonlinear oscillations in multi-species plasma is revisited to provide more insight into the physics of phase mixing by constructing two sets of nonlinear solutions up to the second order. The first solution exhibits perfect oscillations in the linear regime and phase mixing appears only nonlinearly in the second order as a response to the ponderomotive forces. This response can be both direct and indirect. The indirect contribution of the ponderomotive forces appears through self-consistently generated low frequency fields. Furthermore, the direct and indirect contributions of the ponderomotive forces on the phase mixing process is explored and it is found that the indirect contribution is negligible in an electron-ion plasma and it disappears in the case of electron-positron plasma, yet represents an equal contribution in the electron-positron-ion plasma. However, the second solution does not exhibit any phase mixing due to the absence of ponderomotive forces but results in an undistorted nonlinear traveling wave. These investigations have relevance for laboratory/astrophysical multi-species plasma.Comment: Accepted in Physics of Plsama

    The objective of this paper is to provide preliminary analysis of information collected at household level from beneficiaries of the Chiranjeevi scheme and from those who have not used the scheme (non-user group). The key findings have been discussed. Some of the questions which have guided this exercise are: understanding the socio-economic profile and differences of the households who have used the scheme and those who have not used the scheme, ability of scheme to target the poor and out-of-pocket expenditures incurred both users and non-users of the scheme. We have discussed this by analysing education, land holding, number of earning members in the family, possession of specific assets, age of women at the time of delivery, ANC services received, place of delivery, distance and time taken to reach the facility, status (normal or complication) of delivery, complications experienced, and cost incurred during the process. The total sample size consists of 656 respondents from 3 talukas of Dahod District. Of these total 656 respondents, 262 (40 per cent) are Chiranjeevi clients and 394 (60 per cent) comprise the non-user group. Key findings of the study are: * The Chiranjeevi scheme is being used by relatively younger mothers and having lesser number of children at the time of index delivery. * Most of the Chiranjeevi users have income levels less than Rs. 12,000 per annum indicating the scheme is able to target the poor families in these three blocks of the district, * The expenditure incurred by non-user group on index (recent) delivery at a private facility is Rs. 4000. * The average expenditure incurred by the Chiranjeevi beneficiary on their previous delivery was Rs. 3070. On index delivery a Chiranjeevi client has spent out-of- pocket on an average Rs. 727 per delivery on medicine (self Rs. 297, child Rs. 358) and transportation Rs.72 indicating that the delivery is not really cash-less. However, the average amount saved by the Chiranjeevi client by availing the benefit of the scheme is Rs 3273 (Rs. 4000 minus Rs. 727). * The average distance travelled by a Chiranjeevi client to reach the health care facility is 13.79 kms and the average time taken is 44 minutes. * The average expenditure on transportation using mostly private transport by a Chiranjeevi client is Rs.272 as compared to Rs. 200 which the Chiranjeevi client is reimbursed, * Private doctors have conducted 41 per cent of deliveries where as rest of the deliveries have been conducted by staff at the private health care facility under the Chiranjeevi scheme, * ANMs have been the source of information to 55 per cent of Chiranjeevi scheme users. Anganwadi workers provided information to 17 percent of the clients and Female Health Workers to 10 per cent of the Chiranjeevi clients. Thus, 82 per cent of the total beneficiaries of the Chiranjeevi scheme were provided information by the community health workers.

    Financial intermediation and employment

    This paper explores the relationship between financial intermediation and employment. We explain why some economies have low financial intermediation even when financial intermediation is safe. Moreover, we seek to explain why these economies tend to be poor and vulnerable, and also have large self-employment even when the latter has low productivity. We model safe but unsound banks and show that the effects of bad banking can be overcome only partially by corrective taxes. The model is extended to incorporate the illegal sector of the economy as well as the labor laws.Financial intermediation, self-employment, tax, labor laws

    Nonlinear electrostatic oscillations in a cold magnetized electron-positron plasma

    We study the spatio-temporal evolution of the nonlinear electrostatic oscillations in a cold magnetized electron-positron (e-p) plasma using both analytics and simulations. Using a perturbative method we demonstrate that the nonlinear solutions change significantly when a pure electrostatic mode is excited at the linear level instead of a mixed upper-hybrid and zero-frequency mode that is considered in a recent study. The pure electrostatic oscillations undergo phase mixing nonlinearly. However, the presence of the magnetic field significantly delays the phase-mixing compared to that observed in the corresponding unmagnetized plasma. Using 1D PIC simulations we then analyze the damping of the primary modes of the pure oscillations in detail and infer the dependence of the phase-mixing time on the magnetic field and the amplitude of the oscillations. The results are remarkably different from those found for the mixed upper-hybrid mode mentioned above. Exploiting the symmetry of the e-p plasma we then explain a generalized symmetry of our non-linear solutions. The symmetry allows us to construct a unique nonlinear solution up to the second order which does not show any signature of phase mixing but results in a nonlinear wave traveling at upper-hybrid frequency. Our investigations have relevance for laboratory/astrophysical e-p plasmas

    Maternal Healthcare Financing: Gujarat's Chiranjeevi Scheme and Its Beneficiaries

    Maternal mortality is an important public-health issue in India, specifically in Gujarat. Contributing factors are the Government's inability to operationalize the First Referral Units and to provide an adequate level of skilled birth attendants, especially to the poor. In response, the Gujarat state has developed a unique public-private partnership called the Chiranjeevi Scheme. This scheme focuses on institutional delivery, specifically emergency obstetric care for the poor. The objective of the study was to explore the targeting of the scheme, its coverage, and socioeconomic profile of the beneficiaries and to assess financial protection offered by the scheme, if any, in Dahod, one of the initial pilot districts of Gujarat. A household-level survey of beneficiaries (n=262) and non-users (n=394) indicated that the scheme is well-targeted to the poor but many poor people do not use the services. The beneficiaries saved more than Rs 3,000 (US$ 75) in delivery-related expenses and were generally satisfied with the scheme. The study provided insights on how to improve the scheme further. Such a financing scheme could be replicated in other states and countries to address the cost barrier, especially in areas where high numbers of private specialists are available
