Addressing challenges of transition from children's home to independence : Udayan Care's Udayan Ghars (Sunshine Children's Homes) & aftercare programme
Full text linkThe L.I.F.E. Model (Living In Family Environment), is a model that attempts to create familial relationships, consistent living circumstances, and social/educational support systems necessary to move towards independent adulthood for orphaned and vulnerable children (OVC). In addition, the model addresses multiple losses, grief and related issues by employing attachment and trauma-based understandings to child rearing, while using positive psychology tools to encourage resilience and developmental growth. In the last 19 years, Udayan Care (located in New Delhi, India) through the Udayan Ghars Programme and Aftercare Services, has employed an evolved L.I.F.E. model for the children it cares for (Modi, Nayar-Akhtar, Gupta, & Karmakar, 2014). The model includes a family-like regulated support system, with long-term mentors who are set in place to help the children transition from institutional care to independent living. Typically, this takes place with the children moving out of the Sunshine Children's Homes into semi-regulated Aftercare services and then from Aftercare into the larger world. Given the normative transitions for all young persons, finding ways to effectively support institutionalised children as they transition to independent living is critical. In addition to the normative challenges, undoubtedly, institutionalised children come with a history of trauma and abandonment and often have long-term psychological difficulties that are unique to their population. Many such children end up in childcare institutions as there may be no extended family available, and the options for alternative care settings are severely limited. To understand the developmental trajectories of these children, Udayan Care has been participating in longitudinal research to describe the current and on-going changes in children's trauma, attachment, self-concept and ego-resiliency. This work has provided baseline information on the level and effectiveness of the programmes implemented at Udayan Care, and recommends future directions for addressing the children's needs. This paper explores the needs of institutionalised children as addressed by the Udayan Care Model. Such children have histories of severe neglect and need intensive efforts directed towards addressing attachment issues, affect dysregulation, behavioural difficulties, social skills, education and life skills training
Assisting youth leaving care : understanding Udayan care's aftercare programme through the prism of ecological systems theory
Full text linkUdayan Care's aftercare programme for youth is designed to support the transition of young adults leaving the umbrella of the Udayan Care Ghars (Sunshine Homes) to independent and self-reliant living. The objective of this research is to understand the aftercare programme by applying the ecological systems theory of human development formulated by Bronfenbrenner (1979). The study focuses on eight analytical domains that are important for transition of youth namely education and employment, financial management, mental and physical health, legal rights and responsibilities, housing, goals and aspirations, safety and emergency skills, and resilience. It covered 60 youth who are either presently covered under aftercare programme or are Udayan Care alumni who have already availed the organisation’s aftercare support. The life experiences of youth have been presented through five ecological systems namely microsystem, mesosystem, exosystem, macrosystem and chronosystem. The analysis highlights the contributions of multiple stakeholders to the efficacy of the ecological systems. While the success of aftercare programme of Udayan Care is evident in many domains, there are challenges that still exist in regard to building resilience

Textual non-presence : some remarks on Udayan Vajpeyi's poetry
No full textPunktem wyjścia niniejszego tekstu, w którym prezentuję wstępne wyniki moich badań, są założenia dotyczące teorii marzenia sennego (snu), mające swe źródła w psychoanalizie i surrealizmie. Spróbuję przyłożyć te miary do twórczości współczesnego pisarza indyjskiego, by odczytać jej złożony sens. Moim celem jest wytropienie ważniejszych motywów w twórczości poetyckiej pisarza, a także pokazanie, jak stwarza on tekstową rzeczywistość.The aim of my paper is to discuss some important themes in the poetry of Udayan Vajpeyi, and to show how the writer creates a textual reality. Having the theory of dream/sleep as my point of departure, I try to examine the work of a contemporary Indian writer and read its complex meaning. I present here some preliminary results of my research. The analysis of selected poems from the Kuch vāky volume proves that the author uses a variety of techniques, such as montage or collage, specifically relating to Surrealism, and that visuality is the main theme of his poetry. The relation between word, its shape/image and sound constitutes the framework of space functioning on several levels: a poem becomes an artifact which is visual, spatial (watching), acoustic (listening), meaningful (experience, understanding). Therefore, creating poetry defined in this manner is creating "an image" on one hand, on the other - "imaging" a possible reality by collecting "images" together. In the space of a poem both that what is visible/audible (letter/picture/sound) and that what is invisible/inaudible (space/interval/pause) become important and constitute a certain integrity. Thus, the poetic world of Udayan Vajpeyi goes beyond time, beyond verbal frame, allowing the poet to "write" into it some characters and events belonging to the realm of dreams, imagination, visions, and make them real
Anatomical studies on the leaf and stem of Tinospora formanii Udayan & Pradeep (Menispermaceae), an endemic species to Southern Western Ghats, Kerala, India
Full text linkThe anatomical studies on leaf and stem of T. formanii Udayan & Pradeep an endemic species to southern Western Ghats, Kerala, India was carried out focusing on its macroscopic, microscopic, maceration along with organoleptic evaluation. Distinguishing characters of the stem revealed the presence of calcium oxalate crystals, simple and compound starch grains and pitted lignified fibers. Leaf anatomy showed the anomocytic and paracytic stomata, pitted lignified fibers, spiral vessels, non-glandular small trichomes, C or half-moon shaped vascular bundle, surrounded with sclerenchymatous tissues and rosette and prism shaped calcium oxalate crystals. Whereas, maceration studies revealed the presence of spiral and scalar form vessel, fibers, calcium oxalate crystals, simple starch grains. These anatomical studies are vital in the present-day trade scenario not only helpful in the proper identification of the genuine materials in use but also to distinguish different species of Tinospora, where the stem and leaf are often admixed with other species of Tinospora in the crude drug markets
An ultrasensitive colorimetric test for the detection of somatic rare mutations in DNA
No full textTargeted therapies for cutaneous melanoma, such as those based on specific BRAF inhibitors, have improved the treatment and enhanced the survival rate of patients who harbor the V600E point mutation in the BRAF gene. However, tissue biopsies to characterize BRAF mutation status are prone to sampling bias, due to the intrinsic heterogeneity of a tumor mass. In contrast, blood biopsies, which analyze circulating tumor DNA (ctDNA), offer the most complete and sensitive characterization of the mutation status of a tumor, provide early and more accurate diagnosis, but they require instrumental and costly molecular tests. Therefore, the development of low-cost but highly sensitive tests for the non-invasive identification of BRAFV600E mutation in ctDNA would be of great clinical utility as a routine screening for the early identification of responsive patients and the follow-up of targeted therapy's response. The present work developed a naked-eye, inexpensive, yet very specific colorimetric assay, whose sensitivity is suitable for the detection of BRAFV600E rare mutation in ctDNA. Such test potentially may detect at an early stage the mutation in the tumor mass, when the first mutated cells appear in the blood, by using minimal instrumentation and thus enabling its widespread implementation in the clinics, even in local, minimally equipped laboratories. Indeed, the test detects 0.5% of BRAFV600E in an excess of BRAFWT DNA, which matches the sensitivity of some commercial instrumental assays. Such sensitivity is thus clinically relevant for diagnostic purposes, allowing the early identification of drug-sensitive patients
