Maternal Health Financing – Issues and Options: A Study of Chiranjeevi Yojana in Gujarat
No full textGovernment of Gujarat announced a “Chiranjeevi Yojana” in April 2005. The objective of this scheme is to encourage private medical practitioners to provide maternity health services in remote areas which record the highest infant and maternal mortality and thereby improve the institutional delivery rate in Gujarat. The scheme was finally launched as a one year pilot project in December 2005 in five districts viz., Banaskantha, Dahod, Kutch, Panchmahal, and Sabarkantha. The private empanelled providers are reimbursed on capitation payment basis according to which they are reimbursed at a fixed rate for deliveries carried out by them. The payments are made for a batch of 100 deliveries. This is expected to take care of case-mix differences (i.e., normal or complicated deliveries) and help the providers to keep the costs below the reimbursed amounts. The scheme proposes to use a voucher system to target the people living below poverty line. The objective of this paper is to document the experience in implementing this scheme and discuss the issues in up-scaling it further.

Chhapgarus Ng & Trivedi & Bhat 2022, n. gen.
No full textChhapgarus n. gen. Type species. Pseudograpsus intermedius Chhapgar, 1955, by present designation. Description. Carapace squarish, dorsal surface covered with short, brown setae; regions well defined, convex; frontal margin slightly convex, straight; anterolateral margin subcristate with three teeth including first orbital tooth; posterolateral margins not sharply demarcated from anterolateral margin, concave at branchial region, distinctly subparallel; orbits small, eyes completely filling orbit. Third maxillipeds short, stout; small, distinct rhomboidal gape when closed, palp short, with short setae; exopod with short flagellum. Epistome broad, flat, posterior margin entire. Inner surface of chela with granules, setose. Ambulatory legs long, slender with short setae, stout dactyli. Lateral margins of thoracic sternites 4–5 finely granulated; anterior sternal plates without any medial grooves. Male pleon narrowly triangular, with 7 free segments (6 somites plus telson). Female pleon ovate, very broad. G1 stout, gently curving outwards, terminal lobe elongate, slightly curved. Etymology. The new genus is named in honor of Dr. Boman Framji Chhapgar for his valuable contributions to the study of crustacean fauna of Gujarat and Maharashtra States, India. Gender: masculine. Remarks. The description of the genus Pseudograpsus provided by H. Milne Edwards (1837) is brief that has been updated by Ng et al. (2002). In his description, H. Milne Edwards (1837: 81) named two species as belonging to the genus, Pseudograpsus viz. P. pencilliger (Latreille, 1817), and P. pallipes H. Milne Edwards, 1837. No type species was designated. Holthuis (1977) was the first to validly select Cancer penicilliger Latreille, 1817, as the type species (see also Ng & Nakasone 1993: 2). Cancer penicilliger was later synonymized under the senior name, Pseudograpsus setosus (see Ng et al. 2002). The genus Pseudograpsus has a long history of association with Hemigrapsus and Brachynotus (see Tesch 1918; McLay & Schubart 2004; Ng et al. 2002). This association is now being studied in-depth (in preparation). Balss (1934) synonymized P. erythraeus Kossmann, 1894, under P. elongatus. Ng & Nakasone (1993) transferred P. laniger to their new genus, Scutumara Ng & Nakasone, 1993, with a comment that the genus Pseudograpsus needs to be revised. The genus, Pseudograpsus, currently comprises of five species viz. P. setosus (Fabricius, 1778) (= P. pencilliger (Latreille, 1817), type species); P. crassus A. Milne-Edwards, 1868, P. albus Stimpson, 1858, P. elongatus A. Milne-Edwards, 1873, and P. intermedius Chhapgar, 1955. Out of these five species, P. intermedius varies from other species of Pseudograpsus s.s. in having setae on the carapace, chela having soft setae on outer surface, broad and stout ambulatory legs and differences in morphology of reproductive structures, hence Chhapgarus n. gen. is established for Pseudograpsus intermedius Chhapgar, 1955. Interestingly, C. intermedius comb. nov. inhabits the mid-intertidal zone in mangrove habitats (Chhapgar 1955), while species of Pseudograpsus s.s. are found in freshwater streams and/or under pebbles/coral sand habitats along beaches (Tesch 1918; Balss 1922; H.T. Shih, pers. comm). The morphological differences between Chhapgarus n. gen. and Pseudograpsus are given in Table 1. Chhapgarus n. gen., also shows similarity to Utica White, 1847 in having setae on the carapace surface and outer surface of chela, but differs from the latter in the following characters: carapace squarish (versus distinctly quadrangular in Utica); gastric region without “V” shaped ridge (versus prominent “V” shaped ridge on gastric region in Utica); branchial region without horizontal ridge (versus horizontal setose granulated ridge present across the branchial region in Utica).Published as part of Ng, Ngan Kee, Trivedi, Jigneshkumar & Bhat, Mithila, 2022, Redescription of Pseudograpsus intermedius Chhapgar, 1955 (Decapoda, Brachyura, Varunidae) from India, pp. 127-138 in Zootaxa 5209 (1) on page 130, DOI: 10.11646/zootaxa.5209.1.7, http://zenodo.org/record/732261
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
No full text“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Accelerating messages by avoiding copies using RDMA in an asynchronous parallel runtime system
No full textWith the advent of Exascale computing, the number and size of messages is expected to increase greatly. One sided communication with the help of Remote Direct Memory Access (RDMA) supported hardware is the natural choice for large messages as it has proven to provide reduced latencies and increased bandwidth for large payloads in High Performance Computing (HPC) networks. Using RDMA technology enables the network to bypass the Operating System and perform data transfers without the involvement of the Central Processing Unit (CPU). In addition to not consuming CPU cycles, using RDMA also benefits from zero copy networking where the data being transferred is not copied between the layers of the network stack.
Since memory performance is significantly lesser than the CPU performance, it has been observed that memory intensive operations reduce application performance and increase energy consumption. For this reason, reducing memory pressure by saving the cost of allocation and copy helps in improving application performance significantly.
The asynchronous message sending paradigm in Charm++ makes a copy of the payload at the sender side. It also requires copying the data from the message into the user's data structure at the receiver side. As the payload gets larger, the cost of these allocations and copies also increase proportionally. In this thesis, we show the benefits of avoiding the copies at both the sender and receiver side using RDMA on different applications. We also discuss the design of the zero copy user level Application Programming Interface (API) in Charm++ along with the underlying RDMA implementations for different networks in today's supercomputers.Submission original under an indefinite embargo labeled 'Open Access'.

Decomposition of oxalate by streptomyces
No full textThe microbial degradation of oxalate is relatively a rare phenomenon. During the last decade, however, some valuable information on the isolation and study of some more oxalate-decomposing organisms, mostly bacteria, has been reported. The work of Bhat and Barker, Janota, Müller, Khambata and Bhat and Jayasuriya has contributed substantially in this direction. Nevertheless, there seems to be no published data available on the decomposition of oxalate by Streptomyces and, so far as we are aware, this is the first report on this subject
A 22-nm FDSOI CMOS Low Noise active balun achieving < -44-dBc HD3 up to 1.5-V p-p output swing over 0.01-5.4-GHz for direct RF sampling applications
No full textIn this article, we propose a CMOS active balun targeting high linearity up to high voltage swing and over wide bandwidth for direct RF sampling applications. All the blocks of this active balun are derived using a common highly linear building block (HLBB). The HLBB is designed using an inverter with strong source degeneration. To increase the linearity of this HLBB further, its nonlinearity mechanisms are analyzed in detail. A bootstrapping technique is included in the HLBB to reduce the dominant nonlinearity. Furthermore, a pre-distortion technique cancels most of the non-linearity of the output driving stages. All the linearization techniques proposed are robust to process, voltage, and temperature (PVT) changes. The measured results of the active balun realized on-chip in a 22-nm FDSOI CMOS shows < - 44-dBc third harmonic distortion (HD3) up to 1.5- V p-p output swing over 0.01-5.4 GHz. The measured gain and phase errors of the balun action are less than 0.5 dB and ± 5, respectively. The chip is powered from a 5-V supply and dissipates 925 mW.</p
Haemaphysalis davisi Hoogstraal, Dhanda and Bhat 1970
No full textHaemaphysalis davisi Hoogstraal, Dhanda and Bhat, 1970 Haemaphysalis davisi was described from the Myitkyina area of northern Myanmar, with additional collections from northeastern India, occurring in both tropical and temperate zones between 140 m and 2,750 m (Dhanda et al. 1970). Adults have been found on domestic cattle, sheep, goats, horses, mules and hybrids between domestic cattle and gaur (Bos gaurus), as well as various wild deer species, gaur, tiger (Panthera tigris tigris) and hog badger (A. collaris). Nymphs occur on a similar range of hosts (Geevarghese and Mistra 2011) but larval hosts are unknown. The male, female and nymph are described in Hoogstraal et al. (1970).Published as part of Petney, Trevor N., Boulanger, Nathalie, Saijuntha, Weerachai, Chitimia-Dobler, Lidia, Pfeffer, Martin, Eamudomkarn, Chatanun, Andrews, Ross H., Ahamad, Mariana, Putthasorn, Noppadon, Muders, Senta V., Petney, David A. & Robbins, Richard G., 2019, Ticks (Argasidae, Ixodidae) and tick-borne diseases of continental Southeast Asia, pp. 1-89 in Zootaxa 4558 (1) on page 24, DOI: 10.11646/zootaxa.4558.1.1, http://zenodo.org/record/261312
