Education, poverty and "purity" in the context of adolescent girls' secondary school retention and dropout: A qualitative study from Karnataka, southern India.

BACKGROUND: Gender-related norms and poverty remain important structural barriers to secondary school attendance among adolescent girls in southern India. We analyse how gender norms interact with family deprivation and dynamics to result in girls dropping out of school; we identify the main facilitators of school retention and changes to gender socialisation. METHODS: Longitudinal qualitative case studies with 36 girls were nested within a cluster randomized trial to evaluate the Samata intervention targeting adolescent girls in Bagalkote and Vijayapura districts in northern Karnataka. We used two rounds of in-depth interviews, conducted in 2014 at a time when respondents were in 8th standard at the age of 13 to 14 and sixteen months later. We combined thematic and narrative analyses. RESULTS: Our study found that poverty and socioeconomic realities at the household level strongly affect conformity with discriminatory gender practices such as restricting girls' mobility. The value placed on education by parents clearly differentiates the regular school goers from those frequently absent and others who dropped out. With active encouragement of the girls' educational and career aspirations, parents engendered the girl's agency to communicate openly both at home and at school, allowing subtle changes to gender performance while resisting the pressure of social sanctions. In contrast, where educational aspirations were weak, parents invested more intensely in enforcing correct performance of gender, prioritising her well-being by aiming to secure her future in a good marriage. Among poorer families, girls' domestic duties came at the cost of schooling with concerns about protecting her sexual purity predominating. CONCLUSIONS: In contexts where a strong gender ideology of virginity before marriage rules, subtle shifts in harmful gender practices are possible. Interventions aiming to improve education need to target the most deprived families, focussing on trust building through open communication

A community-based qualitative study on the experience and understandings of intimate partner violence and HIV vulnerability from the perspectives of female sex workers and male intimate partners in North Karnataka state, India.

BACKGROUND: Research has increasingly documented the important role that violence by clients and the police play in exacerbating HIV vulnerability for women in sex work. However few studies have examined violence in the intimate relationships of women in sex work, or drawn on community partnerships to explore the social dynamics involved. A community-based participatory research study was undertaken by community and academic partners leading intimate partner violence (IPV) and HIV prevention programs in Bagalkot district, Karnataka state, India. The purpose was to explore the experience and understandings of intimate partner violence and HIV/AIDS among women in sex work and their intimate partners in Bagalkot that would inform both theory and practice. METHODS: A community-based, interpretive qualitative methodology was used. Data was collected between July and October 2014 through in-depth interviews with 38 participants, including 10 couples, 13 individual female sex workers, and 5 individual male intimate partners. Purposive sampling was done to maximize variation on socio-demographic characteristics. Thematic content analysis was conducted through coding and categorization for each interview question in NVivo 10.0, followed by collaborative analysis to answer the research questions. RESULTS: The results showed that an array of interrelated, multi-level factors underlay the widespread acceptance and perpetuation of violence and lack of condom use in participants' intimate relationships. These included individual expectations that justified violence and reflected societal gender norms, compounded by stigma, legal and economic constraints relating to sex work. The results demonstrate that structural vulnerability to IPV and HIV must be addressed not only on the individual and relationship levels to resolve relevant triggers of violence and lack of condom use, but also the societal-level to address gender norms and socio-economic constraints among women in sex work and their partners. CONCLUSION: The study contributes to a better understanding on the interplay of individual agency and structural forces at a time when researchers and program planners are increasingly pondering how best to address complex and intersecting social and health issues. Ongoing research should assess the generalizability of the results and the effectiveness of structural interventions aiming to reduce IPV and HIV vulnerability in other contexts

Investigation on the resonant oscillations in an 11kV distribution transformer under standard and chopped lightning impulse overvoltages with different configurations of shield placements

This paper presents an investigation on the resonant oscillations of an 11 kV layer-type winding transformer under standard and chopped lightning impulse overvoltage conditions based on calculated parameters. The resistances, inductances and capacitances were calculated in order to develop the transformer winding equivalent circuit. The impulse overvoltages were applied to the high voltage (HV) winding and the resonant oscillations were simulated for each of the layers based on different electrostatic shield placement configurations. It is found that the placement of grounded shields between layer 13 and layer 14 results in the highest resonant oscillation and non-linear initial voltage distribution. The oscillation and linear stress distributions are at the lowest for shield placement between the HV and low voltage (LV) windings

Investigation on the transient voltage in a 11 kV transformer under lightning surges

This paper investigates the transient voltage distribution in a 11 kV layer type winding transformer under a standard 1.2/50 µs lightning impulse. The winding parameters known as resistance (R), inductance (L) and capacitance (C) were obtained through numerical calculation which were used to simulate the lumped equivalent circuit model. The calculated and simulated voltage distributions in all the layers of HV winding were analyzed. There is a steep and linear distribution of simulated and calculated voltage

The Samata intervention to increase secondary school completion and reduce child marriage among adolescent girls: results from a cluster-randomised control trial in India.

BACKGROUND: Secondary education and delayed marriage provide long-term socio-economic and health benefits to adolescent girls. We tested whether a structural and norms-based intervention, which worked with adolescent girls, their families, communities, and secondary schools to address poverty, schooling quality and gender norms, could reduce secondary school drop-out and child marriage among scheduled-caste/scheduled-tribe (SC/ST) adolescent girls in rural settings of southern India. METHODS: 80 of 121 villages in Vijayapura and Bagalkote districts, Karnataka State, were randomly selected (control?=?40; intervention?=?40). All 12-13 year-old SC/ST girls in final year of primary school (standard 7th) were enrolled and followed for 3 years (2014-2017) until the end of secondary school (standard 10th). Primary trial outcomes were proportion of girls who completed secondary school and were married, by trial end-line (15-16 years). Analyses were intention-to-treat and used individual-level girl data. RESULTS: 92.6% (2275/2457) girls at baseline and 72.8% (1788/2457) at end-line were interviewed. At end-line, one-fourth had not completed secondary school (control?=?24.9%; intervention?=?25.4%), and one in ten reported being married (control?=?9.6%; intervention?=?10.1%). These were lower than expected based on district-level data available before the trial, with no difference between these, or other schooling or sexual and reproductive outcomes, by trial arm. There was a small but significant increase in secondary school entry (adjusted odds ratio AOR?=?3.58, 95% confidence interval CI?=?1.36-9.44) and completion (AOR=1.54, 95%CI?=?1.02-2.34) in Vijayapura district. The sensitivity and attrition analyses did not impact the overall result indicating that attrition of girls at end-line was random without much bearing on overall result. CONCLUSIONS: Samata intervention had no overall impact, however, it added value in one of the two implementation districts- increasing secondary school entry and completion. Lower than expected school drop-out and child marriage rates at end-line reflect strong secular changes, likely due to large-scale government initiatives to keep girls in school and delay marriage. Although government programmes may be sufficient to reach most girls in these settings, a substantial proportion of SC/ST girls remain at-risk of early marriage and school drop-out, and require targeted programming. Addressing multiple forms of clustered disadvantage among hardest to reach will be key to ensuring India "leaves no-one behind" and achieves its gender, health and education Sustainable Development Goal aspirations.

Correlates of school dropout and absenteeism among adolescent girls from marginalized community in north Karnataka, south India.

Secondary education among lower caste adolescent girls living in rural Karnataka, South India, is characterized by high rates of school drop-out and absenteeism. A cross-sectional baseline survey (N=2275) was conducted in 2014 as part of a cluster-randomized control trial among adolescent girls (13-14 year) and their families from marginalized communities in two districts of north Karnataka. Bivariate and multivariate logistic regression models were used. Overall, 8.7% girls reported secondary school dropout and 8.1% reported frequent absenteeism (past month). In adjusted analyses, economic factors (household poverty; girls' work-related migration), social norms and practices (child marriage; value of girls' education), and school-related factors (poor learning environment and bullying/harassment at school) were associated with an increased odds of school dropout and absenteeism. Interventions aiming to increase secondary school retention among marginalized girls may require a multi-level approach, with synergistic components that address social, structural and economic determinants of school absenteeism and dropout

Global injury morbidity and mortality from 1990 to 2017 : results from the Global Burden of Disease Study 2017

Correction:Background Past research in population health trends has shown that injuries form a substantial burden of population health loss. Regular updates to injury burden assessments are critical. We report Global Burden of Disease (GBD) 2017 Study estimates on morbidity and mortality for all injuries. Methods We reviewed results for injuries from the GBD 2017 study. GBD 2017 measured injury-specific mortality and years of life lost (YLLs) using the Cause of Death Ensemble model. To measure non-fatal injuries, GBD 2017 modelled injury-specific incidence and converted this to prevalence and years lived with disability (YLDs). YLLs and YLDs were summed to calculate disability-adjusted life years (DALYs). Findings In 1990, there were 4 260 493 (4 085 700 to 4 396 138) injury deaths, which increased to 4 484 722 (4 332 010 to 4 585 554) deaths in 2017, while age-standardised mortality decreased from 1079 (1073 to 1086) to 738 (730 to 745) per 100 000. In 1990, there were 354 064 302 (95% uncertainty interval: 338 174 876 to 371 610 802) new cases of injury globally, which increased to 520 710 288 (493 430 247 to 547 988 635) new cases in 2017. During this time, age-standardised incidence decreased non-significantly from 6824 (6534 to 7147) to 6763 (6412 to 7118) per 100 000. Between 1990 and 2017, age-standardised DALYs decreased from 4947 (4655 to 5233) per 100 000 to 3267 (3058 to 3505). Interpretation Injuries are an important cause of health loss globally, though mortality has declined between 1990 and 2017. Future research in injury burden should focus on prevention in high-burden populations, improving data collection and ensuring access to medical care.Peer reviewe

Frequency responses of transformer winding deformations based on finite element modeling under transient overvoltage impulses

Frequency Response Analysis (FRA) is one of the best approaches to detect the mechanical integrity of transformer windings. FRA can be measured on-site or simulated based on the transformer’s design information. The calculations of Resistance (R), Inductance (L), Capacitance (C) and Conductance (G) parameters are essential to simulate the frequency responses based on transfer function and Multi-conductor Transmission Line (MTL) methods. These methods however could not provide detail conditions of the individual windings as well as the cause and effect of mechanical movements. The known causes such as the lightning strikes or switching events could lead to the amplification/attenuation of the overvoltages along the windings and subsequently result in abnormal voltage stresses. The electromagnetic fields could be generated and result in electromechanical effects which need to be classified. Hence, this project is carried out to address the stated issues. First, an alternative approach to extract transformer’s winding RLCG parameters based on Finite Element Method (FEM) was proposed. The C and G were computed based on Fast Multipole Method (FMM) and Method of Moment (MoM) through quasi-electrostatics approach. The AC resistances and inductances were computed based on MoM through quasi-magnetostatics approach. Maxwell's equations were used to\ud compute the DC resistances and inductances. Based on the FEM computed parameters, the frequency response of the winding was simulated through the Bode plot function. The simulated frequency response by FEM model was compared with the simulated frequency response based on the MTL model and the measured frequency response of HV winding for 33/11 kV transformer. Next, the resonant oscillations of HV layer and disc types windings for 11/0.415 kV and 33/11 kV transformers under different cases of lightning and switching impulses were analyzed. The impulse overvoltage were applied to the HV winding and the resonant oscillations were simulated for each of the layers and discs with consideration on different placement configurations of an electrostatic shield. The effects of different magnitudes of standard lightning impulse on the mechanical displacements and deformations of HV windings of an 11/0.415 kV transformer were also examined based on FEM. The resultant electromagnetic forces acting in axial and radial directions were computed and induced to the winding structure. It is found that the simulated frequency response by FEM model is quite close to measured frequency response at low and mid frequency regions based on Root Mean Square Error (RMSE) and Absolute Sum of Logarithmic Error (ASLE). The voltage stresses along the windings are more linear and the resonant oscillations are the lowest once a floating shield is placed between the HV and LV windings of the 11/0.415 kV and 33/11 kV transformers under different cases of lightning and switching impulses based on error of the slope (SEb). It is observed that the outer column supports of the winding structure for 11/0.415 kV transformer experiences apparent electromechanical stresses and radial buckling deformations are observed. The life and lightning overvoltage impulse withstand capability of the winding is estimated to be 1 × 106 impulse cycles which is lower than the design life of 1 × 109 for the copper conductors based on fatigue life and Von-Mises criterion
