Introduction Lymphatic filariasis causes long term morbidity and hampers the socio-economic status. Apart from the available treatments and medication, control of vector population Culex quinquefasciatus Say through the use of chemical insecticides is a widely applied strategy. However, the unrestrained application of these insecticides over many decades has led to resistance development in the vectors. Methods In order to determine the insecticide susceptibility/resistance status of Cx. quinquefasciatus from two filariasis endemic districts of West Bengal, India, wild mosquito populations were collected and assayed against six different insecticides and presence of L1014F; L1014S kdr mutations in the voltage-gated sodium channel gene was also screened along with the use of synergists to evaluate the role of major detoxifying enzymes in resistance development. Results The collected mosquito populations showed severe resistance to insecticides and the two synergists used–PBO (piperonyl butoxide) and TPP (triphenyl phosphate), were unable to restore the susceptibility status of the vector thereupon pointing towards a minor role of metabolic enzymes. kdr mutations were present in the studied populations in varying percent with higher L1014F frequency indicating its association with the observed resistance to pyrethroids and DDT. This study reports L1014S mutation in Cx. quinquefasciatus for the first time.

Conservation Of Biodiversity

The study provides insights into the role of an informal institution of the Santhal tribe of India in the conservation of biodiversity. The data has been collected from 124 Santhal key informants from six tribal districts from the states of Jharkhand (Dumka, Pakur and Sahibganj) and West Bengal (Birbhum, Bankura and West Medinipur) through the methods of stratified sampling, chain-referrals, personal interactions, and focussed group discussions. The taboos associated with biodiversity conservation have been categorized into six categories such as segment taboo, specific-species taboo, life-stage taboo, temporal taboo, habitat taboo and method taboo.

This paper presents the results of an experimental investigation undertaken to evaluate different extractant solutions viz. HCl, Mg(NO3)2, and DTPA with the range of concentration from 0.001 to 0.1Nafter incubation with group-IIB metals (Zn, Cd, and Hg) and EDTA to understand the capability to remove Zn, Cd, and Hg from soils. Two noncontaminated soils, one acidic (GHL) and the other alkaline (KAP), in reaction were taken from an agricultural field of West Bengal, India for this investigation. Experiments were conducted on these two soils spiked with ZnII, CdII, and HgIIin concentrations of 612, 321, and 215 mg/kg for soil GHL and 778, 298, and 157 mg/kg for soil KAP, respectively, which simulate typical electroplating waste contamination. The removal of Zn, Cd, and Hg in soil GHL within the range of HCl concentrations was 8.2–16.5, 12.2–19.1, and 4.3–6.9 whereas these were 6.5–7.6, 8.5–14.1, and 3.2–5.2 in soil KAP. The removal of Zn, Cd, and Hg in soil GHL within the range of Mg(NO3)2concentrations were 12.2–28.5, 19.1–24.6, and 18.2–19.1 whereas these were 9.1–12.1, 8.3–12.1, and 10.6–48.1 in soil KAP. For DTPA extractant, the percent removal of metal was found to be significantly higher than the other two extractants, which corroborates that DTPA is a better extractant for soil cleaning.

Refugee Experience

AbstractWithin the popular memory of the partition of India, the division of Bengal continues to evoke themes of political rupture, social tragedy, and nostalgia. The refugees or, more broadly speaking, Hindu migrants from East Bengal, are often the central agents of such narratives. This paper explores how the scholarship on East Bengali refugees portrays them either as hapless and passive victims of the regime of rehabilitation, which was designed to integrate refugees into the socio-economic fabric of India, or eulogizes them as heroic protagonists who successfully battled overwhelming adversity to wrest resettlement from a reluctant state. This split image of the Bengali refugee as both victim and victor obscures the complex nature of refugee agency. Through a case-study of the foundation and development of Bijoygarh colony, an illegal settlement of refugee-squatters on the outskirts of Calcutta, this paper will argue that refugee agency in post-partition West Bengal was inevitably moulded by social status and cultural capital. However, the collective memory of the establishment of squatters’ colonies systematically ignores the role of caste and class affiliations in fracturing the refugee experience. Instead, it retells the refugees’ quest for rehabilitation along the mythic trope of heroic and masculine struggle. This paper interrogates refugee reminiscences to illuminate their erasures and silences, delineating the mythic structure common to both popular and academic refugee histories and exploring its significance in constructing a specific cultural identity for Bengali refugees.

This Chapter 4 gives a nuanced picture of the role of mobile phones in economic activities in rural West Bengal. Rather than juxtaposing economic and social uses, it explores them in tandem. How are phones used instrumentally and socially, and how do these different uses mesh and interrelate? The chapter also looks at how phone use influences social relationships, including their use for health care. Furthermore, the chapter assesses how the enhancement of logistical efficiency with the help of phones relates to development as economic growth and increased well-being. It highlights that not all people received equal economic benefits from phones. Phones have been most beneficial for the wealthiest entrepreneurs and large farmers. Those entrepreneurs whose markets extend outside the village have benefitted more than those who mainly market their products and services in the village.

SummaryStudies examining the influence of community-level interactions and contextual/supply-side factors in determining contraceptive choices have yielded mixed results in the context of rural India. Using small-scale survey data of 1348 women from rural West Bengal and by employing multilevel multinomial logit models, this study tested the influence of these factors after controlling for various socio-demographic and individual-level socioeconomic factors. The study reveals that supply-side intervention strategies, i.e. addressing outreach and advocacy activities and socio-religious needs at the community level, are essential prerequisites to breaking away from the predominance of sterilization in the contraceptive method-mix and enhancing the adoption of modern reversible contraceptives for improved spacing of births – a crucial factor in maternal and child health outcomes.
