Sex trafficking of girls and women : Evidence from Anantapur district, Andhra Pradesh
No full textA crucial gap in the trafficking literature from India is the dearth of primary data and micro studies that could be used for vulnerability mapping of the source areas and addressing the identified risk factors. The present paper is a small attempt to contribute to plugging the gap in the context of Andhra Pradesh, identified as a hot spot in the trafficking literature. This paper is based on case studies of 78 women who had been trafficked from their places of origin in Anantapur district in Andhra Pradesh to metropolitan cities across India and who have since returned to their homes. The paper attempted to identify the individual and family circumstances that contribute to the causes of trafficking, to highlight in particular the gendered vulnerabilities that set these women up for trafficking, and to capture the process of the trafficking experience. The findings of the study are located in the dynamic interplay of the social structural context and specificities of the district that contribute to causes of trafficking and the individual circumstances and agency of the women. The case studies reported in this paper are a pointer to the compelling urgency of interventions that will go beyond the forced / voluntary divide in trafficking and sex work.Andhra Pradesh, India, trafficking

Unveiling the ChatGPT Educational Revolution: Assessing the Dynamic Impact on Students and Educators
No full textDue to shifting social demands and technology breakthroughs, the higher education environment is changing quickly. Despite initiatives to make education accessible to everyone, accessibility is still a major problem, especially in light of the digital divide. This study investigates how ChatGPT, an AI-powered chatbot, can revolutionize higher education by tackling important problems including resource efficiency, personalized learning, and accessibility. This study intends to improve learning outcomes for both students and educators by comprehending how instructors and students incorporate ChatGPT into instructional methods. Students and instructors were given both quantitative and qualitative questionnaires as part of a mixed-methods approach, in order to gather data on the usage of ChatGPT for different academic tasks, such as lesson preparation, grading, and student help. Results showed that most people believe ChatGPT to be a useful tool that improves productivity, saves time, and helps with grasping difficult subjects. Questions were raised concerning the veracity of the data that ChatGPT offered and the necessity of organized training. ChatGPT and other AI technologies have the potential to enhance educational results by enabling personalized instruction and offering on-demand learning help. In addition to the continuing discussion on the use of cutting-edge technology in higher education, the findings provide insightful information for educational institutions seeking to use AI to improve teaching and learning.

Matching in power graphs of finite groups
No full textFunding: The author Swathi V V acknowledges the support of Council of Scientific and Industrial Research, India (CSIR) (Grant No-09/874(0029)/2018-EMR-I), and DST, Government of India, ‘FIST’ (No.SR/FST /MS-I/2019/40).The power graph P(G) of a finite group G is the undirected simple graph with vertex set G, where two elements are adjacent if one is a power of the other. In this paper, the matching numbers of power graphs of finite groups are investigated. We give upper and lower bounds, and conditions for the power graph of a group to possess a perfect matching. We give a formula for the matching number for any finite nilpotent group. In addition, using some elementary number theory, we show that the matching number of the enhanced power graph Pe(G) of G (in which two elements are adjacent if both are powers of a common element) is equal to that of the power graph of G.Peer reviewe
Characterization of the flow-field in circular subsonic impinging jets: Investigation of surface pressure fluctuations and far-field noise emissions through pressure sensor measurements
No full textImpinging jets are relevant ow configurations in many technological developments. For example, on some short take-off and landing aircraft the high speed exhaust from the jet engine is deflected by direct impingement on the aps to create extra lift during take-off. Fatigue due to excessive dynamic loading on the aps and high levels of noise radiation are among the problems encountered in such designs. Additionally, such flow-structure interaction is a good model for cooling of turbine blades, annealing of plastic and metal sheets, deicing of aircraft systems etc.. Jets are easy to simulate and contain all the constituents necessary for the study of shear flows. The shear-layer instability at the nozzle edge develops into axisymmetric toroidal vortices which magnifies in size and strength downstream of the nozzle. The interaction of these vortices with the solid structures induces pressure fluctuations that manifests in the form of noise in the far-field region. Hence, it is also a benchmark case for studying vortex-structure interaction noise.Aerospace Engineering | Aerodynamics and Wind Energ
Somaesthetic Encounters with Socrates: The Peaceful Warrior as Yogi
No full textThe body perfects itself: It is the subjective site of personal transformation, hence, the somaesthetic Body. It is, simultaneously, the objective site of inspired transformation, hence, the Mentored Body, the cared-for Body. This thesis is examined through Peaceful Warrior: The Graphic Novel (2010), which is Dan Millman’s autobiografiction, illustrated by Andrew Weingarner. The paper interprets Dan Millman’s journey by employing Richard Shusterman’s theory of somaesthetics as well as the classical Indian treatise of Patanjali called the Yoga Sūtra. The paper is built around the idea of the “Mentor”- here, Socrates - who must guide the disciple (Dan Millman) to “greater perceptual acuity.” To this end, it reflects on: 1. “Socrates” as an idea; 2. The relationship between the Field (which is the classical image of the Body) and the Farmer (here, the Mentor); 3. The building of the Peaceful Warrior, and 4.The culmination of the journey when the Peaceful Warrior becomes the Yogi.The moment of awakening in the narrative is when Socrates declares to Dan that, “this world is a school” where one must discover his purpose. The Mentor guides the seeker towards his purpose. The seeker journeys towards the purpose by moving from the outermost somatic territory through routines called Bahiraṅga Sādhana into the inner territory of the mind involving routines called Antaraṅga Sādhana and, eventually, arrives at the innermost territory of the soul through routines called Antarātma Sādhana. The journey from the somatic territory towards the territory of the Soul takes the seeker through four degrees of wakefulness – sleep (Nidrāvasthā); dream (Svapnāvasthā); wakefulness (Jāgratāvasthā); eternal wakefulness (Turyāvasthā). The journey towards the Soul places somaesthetic demands that are satisfied by observing the eight aspects of Yoga: Yama, Niyama, Āsana, Prāṇāyāma, Pratyāhāra, Dhāraṇā, Dhyāna, Samādhi. In the process, the seeker traverses all the three domains of Yoga: Karmamārga (actions centred in the body); Jňānamārga (actions centred in the mind); Bhaktimārga (actions centred in the Soul). The seeker commits his body (the subjective site) to the purpose. The seeker is inspired by the Mentor to become a warrior as he battles the forces of inertia entrenched in him. When the peaceful warrior arrives at superconsciousness he completes the journey of the Yogi

Epigenetic silencing of ID4 in prostate cancer: mechanistic insight, 2015
No full textInhibitor of DNA binding/differentiation protein 4 (ID4) is a dominant negative regulator of basic helix loop helix (bHLH) family of transcription factors. ID4 shares the homology of HLH domain with other ID proteins (ID1, ID2, and ID3) and lack the basic DNA binding region. Evidence suggested that unlike ID1, ID2 and ID3, ID4 acts as a tumor suppressor in prostate cancer by attenuating cell proliferation and promoting apoptosis. Consistent with these observations ID4 is epigenetically silenced in DU145 prostate cancer cell line. In this study we investigated whether ID4 is also epigenetically silenced in prostate cancer. We also examined association between ID4 promoter hyper-methylation and its expression in prostate cancer cell lines. ID4 protein expression was analyzed in human prostate adenocarcinoma samples by Immunohistochemistry (IHC). ID4 promoter methylation pattern on prostate cancer cell lines was examined by methylation specific PCR. In addition, we performed methylation specific PCR on the human prostate tissues and genomic DNA to correlate cell line studies with clinical studies. IHC demonstrated decreased ID4 protein expression in human prostate tissue samples, whereas higher nuclear ID4 expression was found in normal prostate tissues. ID4 methylation specific PCR (MSP) on prostate cancer cell lines, showed ID4 methylation in DU145, but not in LNCaP and C33 cells. C81 and PC3 cells showed partial methylation. Increased ID4 methylation in C81 as compared to LNCaP suggests its epigenetic silencing as cells acquire androgen independence. Tumors with ID4 promoter hyper-methylation showed distinct loss of ID4 expression. However, the underlying mechanism involved in epigenetic silencing of ID4 is currently unknown. We hypothesized that ID4 promoter methylation is initiated by an EZH2 dependent tri-methylation of histone 3 at lysine 27 (H3K27Me3). ID4 expressing (LNCaP) and non-expressing (DU145 and C81) prostate cancer cell lines were used to investigate EZH2, H3K27Me3 and DNMT1 enrichment on ID4 promoter by Chromatin immuno-precipitation (ChIP). Increased enrichment of EZH2, H3K27Me3 and DNMT1 in DU145 and C81 cell lines was compared to ID4 expressing LNCaP cell line. Knockdown of EZH2 in DU145 cell line led to re-expression of ID4 and decrease in enrichment of EZH2, H3K27Me3 and DNMT1 demonstrating that ID4 is regulated in an EZH2 dependent manner. ChIP on prostate cancer tissue specimens and cell lines suggested EZH2 occupancy and H3K27Me3 marks on the ID4 promoter. Collectively, our data indicate a PRC2 dependent mechanism in ID4 promoter silencing in prostate cancer through recruitment of EZH2 and a corresponding increase in H3K27Me3. Increased EZH2, but decreased ID4 expression in prostate cancer strongly supports this model.
