Silences and Voices of transpersons or Transgenders of India: A Historical Analysis

Despite the high status given to transgender community in India in age old times, with the coming of British rule, their condition started worsening. They were silenced for decades. From the struggles they are facing since British rule, they have reached too far. Yet they have not achieved their full freedom. However, some of them tried to fight against the injustice they are facing and they took different steps for their struggle. This paper attempts to highlight the status oftransgenders since age old times and also how they try to create a space of their own through various mediums like law, literature etc and their achievements too far

Making space for women in urban governance? Leadership and claims-making in a Kerala slum

This paper looks at the role of gender in the shaping and exercise of political authority. Its empirical focus is a slum in central Trivandrum, Kerala's capital city, which is undergoing a phased process of formalisation and rebuilding funded through a flagship Indian national programme, the JNNURM. The upgrade project should offer a dense network of ‘invited’ spaces for female participation within urban governance, both through women's presence within democratically elected municipal councils, and the deliberate linking of its implementation to Kudumbashree, Kerala's network of women-only neighbourhood groups that are responsible for implementing various antipoverty interventions throughout the state. Drawing on oral histories of the slum's evolution, interviews with project participants, and detailed ethnographic observation, we highlight the contests over identifying the list of JNNURM beneficiaries who would ultimately be granted a government-built flat at the project's completion. This key task in the project's implementation has been devolved to the local level, and therefore offers important insights into the practical efficacy of these invited spaces. The contests over this list show how ‘actually existing’ urban governance unfolds, and in particular highlight the interplay of formal and informal practices at work in ‘fixing’ a list that had local legitimacy. They also illustrate the ways in which power and authority are contested, and the role gender plays within performances of leadership. Women's political agency and efficacy are hampered both by Kerala's restrictive gender norms and by the high stakes and highly masculinist struggles present within its urban politics. The paper's theoretical contribution is to broaden our conceptualisation of leadership and claims making in the Global South, and within this to pay proper attention to the gendered nature of political space

Effect of different modes of pollination on yield parameters of summer squash (Cucurbita pepo L.) in India

Effect of different modes of pollination, viz., without insect pollination, hand-pollination, open-pollination and open-pollination + hand-pollination on yield parameters of 4 summer squash (Cucurbita pepo L.) hybrids viz., Parikrama, Chandra, Chamatkar and Gold Queen was studied at Research Farm of the Department of Entomology, CCS Haryana Agricultural University, Hisar during 2014. Irrespective of different hybrids, the treatment openpollination + hand-pollination and open-pollination produced the maximum number of fruits per plant (73.50 and 71.25%, respectively) followed by hand-pollination (59.08%) and no fruits were observed (0% fruit set) under without insect pollination treatment. Average fruit weight, fruit polar diameter and equatorial diameter were maximum (135.30 g, 3.74 cm and 3.47 cm, respectively) under open-pollination + hand-pollination, while these were minimum (94.81 cm, 2.14cm and 2.48 cm, respectively) under hand-pollination treatment. These results indicate that honey bees as well as wild pollinators are utmost essential for pollination of summer squash flowers and thus increasing fruit size and yield. Therefore pollinators conservation practices should be followed in summer squash growing areas for getting higher yield and returns

Bio-inspired Optimization: Algorithm, Analysis and Scope of Application

In the last few years, bio-inspired optimization techniques have been widely adopted in fields such as computer science, mathematics, and biology in order to optimize solutions. Bio inspired optimization problems are usually nonlinear and restricted to multiple nonlinear constraints to tackle the problems of the traditional optimization algorithms, the recent trends tend to apply bio-inspired optimization algorithms which represent a promising approach for solving complex optimization problems. This work comprises state-of-art of ten recent bio-inspired algorithms, gap analysis, and its applications namely; Particle swarm optimization (PSO), Genetic Bee Colony (GBC) Algorithm, Fish Swarm Algorithm (FSA), Cat Swarm Optimization (CSO), Whale Optimization Algorithm (WOA), Artificial Algae Algorithm (AAA), Elephant Search Algorithm (ESA), Cuckoo Search Optimization Algorithm (CSOA), Moth flame optimization (MFO), and Grey Wolf Optimization (GWO) algorithm. The previous related works collected from Scopus databases are presented. Also, we explore some key issues in optimization and some applications for further research. We also analyze in-depth discussions on the essence of these algorithms and their connections to self-organization and their applications in different areas of research are presented. As a result, the proposed analysis of these algorithms leads to some key problems that have to be addressed in the future

Heavy road vehicle platoon control considering brake fade with adaptive mass and road gradient estimation

This is the final version. Available from the Institute of Electrical and Electronics Engineers via the DOI in this record. Heavy commercial road vehicle (HCRV) platoons are viable logistic solutions to freight movement. During long haul platoon operation, it is common to encounter roads of different gradients. This paper investigates the effect of brake fade phenomenon, which happens due to the continuous application of brake during downgrade operation on the string stability of HCRV platoons. A brake actuator model incorporating temperature effects during braking and characterizing brake fade has been used. A Sliding Mode Control (SMC) based string stable controller, which compensates for brake fade, has been designed. Since the brake fade factor and hence platoon stability directly depend upon the road gradient and vehicle mass, which are not directly measurable quantities, an algorithm that adaptively estimates the same has been integrated with the controller design. The algorithm could estimate the mass and gradient values with less than 2% mean absolute percentage error. The stability of the proposed fade compensated controller has been analyzed and its efficacy has been tested for various road conditions and for homogeneous and heterogeneous (overloaded cases) platoon operations. The proposed approach was seen to ensure string stability for all the considered test scenarios

Potential Function-Based String Stable Controller for Heavy Road Vehicle Platoons

This is the final version. Available on open access from IEEE via the DOI in this recordHeavy Commercial Road Vehicle (HCRV) platooning is a promising solution to meet increasing freight transportation demands. This paper applies the concept of Artificial Potential Functions (APF) to design a string stable controller, viz., Potential Function-based String Stable (PFSS) controller, for establishing stable HCRV platoons under various operating conditions. A methodical approach for the design and selection of potential functions that would maintain the desired intervehicular spacing in the presence of perturbations has been presented. The proposed methodology has been evaluated on a complete vehicle dynamics model-based platoon framework, which would emulate actual vehicle operation. It provides string stable operation under different lead vehicle perturbation maneuvers on various road friction and slope conditions with homogeneous and heterogeneous loading conditions. Compared to existing string stable control approaches, the proposed PFSS controller has attributes such as minimal data requirement from neighboring vehicles, actuator feasible control actions, and simpler control structures.Ministry of Skill Development and Entrepreneurship, Government of Indi

Sustainable heavy goods vehicle electrification strategies for long-haul road freight transportation

This is the final version. Available from the Institute of Electrical and Electronics Engineers via the DOI in this record. Even though diesel-powered Heavy Goods Vehicles (HGVs) are major contributors of greenhouse gas emission, HGV electrification is still in its infancy owing to various challenges. Costlier and heavier batteries and lack of charging infrastructure along long routes are the major bottlenecks in the realisation of HGV electrification for long-haul freight transportation. In this regard, adopting technologies that can make HGV electrification viable is vital to aid the transportation sector decarbonisation. Benefiting from approaches such as the use of overhead catenary power, and conforming to operate in a platoon formation, it would be possible to considerably reduce the cost of HGV electrification and make it economically feasible. Utilising overhead catenary infrastructure would result in requiring economical charging infrastructure, shorter charging cycles, and smaller batteries, while not compromising on the overall payload of HGVs. HGVs in platoon formation result in energy consumption reduction and increased traffic throughput. This paper investigates the benefits of using overhead catenary-powered electric HGVs for freight transportation and also explores the advantages associated with electric HGV platoon formations on the same. The feasibility analysis has been done with the support of close to real physics-based electric HGV models on realistic operating scenarios adopting an in-service highway drive cycle. From the analysis, electric HGV platooning using overhead catenary as the power source was found to be economical with ≈ 10.4% reduction in electricity cost when compared to without platooning while devising electrification strategies for long-haul freight transportation.City Science, Exete

A Dynamics-Based Adaptive String Stable Controller for Connected Heavy Road Vehicle Platoon Safety

This is the final version. Available on open access from IEEE via the DOI in this recordThis article presents a string stable controller for the autonomous operation of a platoon of Heavy Commercial Road Vehicles (HCRVs) in a connected environment. This study considers factors such as brake/powertrain actuator dynamics, resistive forces, tyre model and wheel dynamics, which are crucial during on-road operation of HCRVs. A nonlinear vehicle dynamic model encompassing all these factors has been considered. The dependency between aerodynamic drag and inter-vehicular distance in the platoon has also been taken into account. The aforementioned factors motivated the use of Sliding Mode Control (SMC), which is a nonlinear and robust control technique. A lower level Proportional Integral Derivative (PID) controller has been successfully integrated with SMC to compensate for pneumatic brake and powertrain system delay. The designed controller was evaluated for string stable platoon operation by considering various road conditions, load conditions and operating speeds. It was observed that the string stable controller performance is highly dependent on the operating conditions. To ensure string stable operation for different operating scenarios, an adaptive time-headway based enhancement has also been integrated in the controller design. The efficacy of the proposed adaptive time-headway policy over the existing constant time-headway policy has been methodically analysed and a performance comparison between them has also been presented. The aspect of communication delay during connected vehicular operation has also been studied and the maximum tolerable communication delay magnitude for maintaining string stable operation has also been presented.Ministry of Skill Development and Entrepreneurship, Government of Indi

Burnout Among Nephrologists in the United States: A Survey Study

Rationale & Objective: Burnout decreases job satisfaction and leads to poor patient outcomes but remains under-investigated in nephrology. We explored the prevalence and determinants of burnout among a sample of nephrologists. Study Design: Cross-sectional. Setting & Participants: The nephrologists were approached via the American Medical Association Physicians Masterfile, National Kidney Foundation listserv, email, and social media between April and August 2019. The predictors were demographics and practice characteristics. The outcome was burnout, defined as responding once a week or more on either 1 of the 2 validated measures of emotional exhaustion and depersonalization or both. Analytical Approach: Participant characteristics were tabulated. Responses were compared using χ2 tests. Multivariable logistic regression was used to estimate the odds ratios (ORs) of burnout for risk factors. Free text responses were thematically analyzed. Results: About half of 457 respondents were 40-59 years old (n=225; 49.2%), and the respondents were more predominantly men (n=296; 64.8%), US medical graduates (n=285; 62.4%), and in academic practice (n=286; 62.6%). Overall, 106 (23.2%) reported burnout. The most commonly reported primary drivers of burnout were the number of hours worked (n=27; 25.5%) and electronic health record requirements (n=26; 24.5%). Caring for ≤25 versus 26-75 patients per week (OR, 0.34; 95% confidence interval [95% CI], 0.15-0.77), practicing in academic versus nonacademic settings (OR, 0.33; 95% CI, 0.21-0.54), and spending time on other responsibilities versus patient care (OR, 0.32; 95% CI, 0.17-0.61) were each independently associated with nearly 70% lower odds of burnout after adjusting for age, sex, race, and international medical graduate status. The free text responses emphasized disinterested health care systems and dissatisfaction with remuneration as the drivers of burnout. Limitations: Inability to precisely capture response rate. Conclusions: Nearly one-quarter of the nephrologists in our sample reported burnout. Future studies should qualitatively investigate how the care setting, time spent on electronic medical records, and hours of clinical care drive burnout and explore other system-level drivers of burnout in nephrology
