Abstract:

Accessing and sharing automobiles will become much simpler thanks to the wide range of automotive use cases made possible by digital keys. This study aims to provide digital keys to car owners and drivers so they can lock or unlock their automobiles and start the engine using a smartphone or other Bluetooth low energy-enabled mobile device. Private automobile owners can digitally lend their car keys to family members or friends without having to physically meet them, possibly for a certain period of time. Owners of company automobile fleets can electronically distribute car keys to staff members, possibly granting access for a given day or length of time. Customers no longer need to physically pick up car keys at a rental desk because automobile owners can digitally transfer keys with them.

Abstract:

The goal of every faculty is to guide students to learn fundamental concepts and also improve thinking skills. Curriculum questionnaires must be framed, which would facilitate students to improve their thinking skills. Improving thinking skill is a difficult task and one of the ways to achieve this is to frame questionnaires using Bloom’s Taxonomy. Bloom’s Taxonomy helps the faculty to assess the students in a systematic approach which involves students performing successfully at each level in a systematic manner. In this paper, we have discussed on Revised Bloom’s Taxonomy and how to frame our questions based on the taxonomy for assessment. We have also presented mapping the questions with the taxonomy table which shows the mapping of the questions in knowledge and cognitive domain.

Abstract:

Polyaniline/gold (PANI/Au) nanocomposite was prepared by in-situ chemical oxidation polymerization method. The synthesis involved the formation of polyaniline-gold nanocomposite, by in-situ redox reaction and the dispersion of gold nano particles throughout the polyaniline matrix. The nanocomposites were characterized by XRD, FTIR, TEM and UV-visible spectroscopy. The characteristic peaks in FTIR and UV-visible spectra confirmed the expected structure of polymer as reported in the literature. Further, transmission electron microscopy (TEM) confirmed the formation of gold nano particles. The crystallite size of 30 nm for nanoAu was supported by the XRD pattern. Further, the A.C. conductivity, dielectric constant (€’(w)) and dielectric loss (€’’(w)) of PANI/Au nano composite was measured using impedance analyzer. The effect of doping on the conductivity was investigated. The antibacterial activity was examined for this nano composite and it was observed that PANI/Au nanocomposite could be used as an antibacterial agent.

Abstract:

Sex trafficking is a traumatic ongoing process which includes human rights violations against the victims. Majority of the trafficked individuals in India are from families with low socioeconomic status, from rural areas, unmarried or married off at a very young age. Many of the sex trafficked feel that it is necessary to make sacrifices, for the benefit of their families. The combination of these cultural family values with the stigma of rape and prostitution are manipulated and used as a tool in the abuse of power against the sex trafficked. The rescue, rehabilitation and reintegration of these individuals are usually difficult due to the stigma and social exclusion that they face. In these circumstances, social support is very effective in social inclusion of these individuals. The present study was a qualitative one, using semi-structured interviews with 29 Indian survivors of sex trafficking and a few sex workers. Thematic analysis was done on the data derived from the semi-structured interviews. The major findings indicate that the family can be seen as both the ‘cause’ for being sex trafficked, and the factor in victim continuing to be sex trafficked. At the same time, it can also become a driver for getting rescued, rehabilitated and reintegrated. The study also explores the social construction about ‘family’ among the survivors of sex trafficking, reflecting on who they refer to as ‘family’, what they mean by the term ‘family’ and how these families emerge. Therefore the analytic concept of ‘family’ is a crucial element in sex trafficking and cannot be defined only in terms of its conventional definition of a basic unit of society.

Abstract:

Hemorrhage is the loss of blood from the circulatory system and leading cause of battlefield and postpartum related deaths. Early detection of hemorrhage remains the most effective strategy to reduce mortality rate caused by traumatic injuries. In this study, we investigated the physiological changes via non-invasive cardiac signals at rest and under different hemorrhage conditions simulated through graded lower-body negative pressure (LBNP). Simultaneous electrocardiogram (ECG), photoplethysmogram (PPG), blood pressure (BP), impedance cardiogram (ICG), and phonocardiogram (PCG) were acquired from 10 participants (age:28 ± 6 year, weight:73 ± 11 kg, height:172 ± 8 cm). The LBNP protocol consisted of applying -20, -30, -40, -50, and -60 mmHg pressure to the lower half of the body. Beat-to-beat heart rate (HR), systolic blood pressure (SBP), diastolic blood pressure (DBP), and mean aerial pressure (MAP) were extracted from ECG and blood pressure. Systolic amplitude (SA), systolic time (ST), diastolic time (DT), and left ventricle Ejection time (LVET) were extracted from PPG during each stage. Preliminary results showed that the application of -40 mmHg i.e. moderate stage simulated hemorrhage resulted significant changes in HR (85±4 bpm vs 68 ± 5bpm, p < 0.01), ST (191 ± 10 ms vs 253 ± 31 ms, p < 0.05), LVET (350 ± 14 ms vs 479 ± 47 ms, p < 0.05) and DT (551 ± 22 ms vs 683 ± 59 ms, p < 0.05) compared to rest, while no change was observed in SA (p > 0.05) as a consequence of LBNP application. These findings demonstrated the potential of cardiac signals in detecting moderate hemorrhage. In future, we will analyze all the LBNP stages and investigate the feasibility of other physiological signals to develop a predictive machine learning model for early detection of hemorrhage.

Abstract:

One of the most poignant forms of organized crime against women, which has rarely made it to the world of Indian cinema, is that of sex trafficking, i.e. the forcible involvement of women in the sex trade through fraud or coercion (Hughes, 2005). In the space of Indian cinema, much of the spotlight has been on the sensational drug trafficking and gang mafia of Bombay. During our research on sex trafficking, the rehabilitated women interviewed often expressed strong criticism about mass media’s naive portrayal of prostitutes as money-minting, happy and sexually driven women. They argued that this unrealistic portrayal ignored the fact that this was not a reality for the majority of trafficked women. Given the gravity of sex trafficking as a human rights issue, it is, therefore, refreshing to see three recent films on sex trafficking in Indian Languages – Naa Bangaaru Talli (2014, Telugu), Mardaani (2014, Hindi) and Lakshmi (2014, Hindi). This paper reviews these three films to explore the portrayal of the everyday reality of trafficking for women. Film analysis was used to understand the representation of psychological issues in the media. The strength of these movies starts with their inspirations which are of true stories and that they are all aimed at bringing awareness about the issue of sex trafficking, which is a rising social evil in Indian society though none of the three films move to portray the next phase of rehabilitation and reintegration of victims, which is a very complex and important process in the life of a survivor. According to findings, survivors of sex trafficking find the rehabilitation and reintegration into society to be a slow and tough part of their life as they continuously face stigma and social exclusion and have to strive to live against all odds of non-acceptance starting from their family.

Abstract:

Sex trafficking is a type of human trafficking involving prostitution of individuals for sexual exploitation. The stigma and social isolation they face in the society often makes it difficult for them to become rehabilitated from trafficking, due to which many of them continue in prostitution for years after being sex trafficked. Victims are subjected to violations of their fundamental human rights, deprived of basic medical facilities and undergo long-term abuse. This paper focuses on the role of Non-Governmental Organizations (NGOs) in the rescue and rehabilitation of victims of sex trafficking. Semi-structured interviews were conducted with 26 survivors of sex trafficking, five sex workers and 14 non-community staff members of a project running NGO in the city of Chennai in South India. Chennai has a number of NGOs that are involved in HIV/AIDS awareness and prevention programs. In many cases, rehabilitation of sex trafficking victims is also a mandate of these NGOs. This particular NGO was also involved in development activities towards the eradication of HIV/AIDS. For instance, they were engaged in inculcating safe sex practices among high-risk groups such as sex workers or in fighting for sex worker rights. The study found that the NGO’s role in combatting sex trafficking is overrun by the way it approaches these issue related to HIV/AIDS. Further, their activities are dependent solely on funding. Given that gradually, international funding for HIV/AIDS has slowly been withdrawn, there have been problems such as reduction in the salary of the project staff, the outreach workers and peer educators, many of whom were survivors of sex trafficking who have been able to survive on their wages instead of continuing in prostitution. Therefore, till date, the project funding has helped in making them aware of the health and social consequences of continuing in prostitution, and in supporting them socioeconomically, but the lack of funding may also lead the NGO workers into a state of unemployment, poverty and eventually into being re-trafficked. The study concludes by pointing to the need for disengaging anti-trafficking efforts from the HIV/AIDS related programs.
