The red rain phenomenon of Kerala and its possible extraterrestrial origin

A red rain phenomenon occurred in Kerala, India starting from 25th July 2001, in which the rainwater appeared coloured in various localized places that are spread over a few hundred kilometers in Kerala. Maximum cases were reported during the first 10 days and isolated cases were found to occur for about 2 months. The striking red colouration of the rainwater was found to be due to the suspension of microscopic red particles having the appearance of biological cells. These particles have no similarity with usual desert dust. An estimated minimum quantity of 50,000 kg of red particles has fallen from the sky through red rain. An analysis of this strange phenomenon further shows that the conventional atmospheric transport processes like dust storms etc. cannot explain this phenomenon. The electron microscopic study of the red particles shows fine cell structure indicating their biological cell like nature. EDAX analysis shows that the major elements present in these cell like particles are carbon and oxygen. Strangely, a test for DNA using Ethidium Bromide dye fluorescence technique indicates absence of DNA in these cells. In the context of a suspected link between a meteor airburst event and the red rain, the possibility for the extraterrestrial origin of these particles from cometary fragments is discussed.Comment: 18 pages, 15 figures, accepted for publication in Astrophysics and Space Scienc

How do we assess the quality of group supervision? : developing a coding framework

The importance of supervision for social work practice is one of the most widely accepted tenets of the profession. Yet, surprisingly little is known about what happens in supervision, making it difficult to unravel what it is about supervision that makes a difference to social work practice. This paper describes the development of a framework for assessing the quality of group supervision. It focuses on one sub-category of group supervision – systemic group supervision – and draws a wider evaluation of systemic social work practice in the UK. It is based on 29 observations of “live” of supervision to illustrate differences in quality of supervisory practice. The process of developing the coding framework was cyclical, and ultimately resulted in a three-point ordinal grouping for assessing systemic supervisory practice. Analysis of observational data assessed group systemic supervision as follows: 8 as non-systemic (28%); 12 (41%) as demonstrating some incorporation of systemic ideas into interactions, described as “green shoots” (or showing encouraging signs of development but not yet reached its full potential); and 9 (31%) supervision sessions demonstrating a full incorporation of systemic concepts and practice. What marked “systemic” sessions from “green shoots” supervision was the move from hypothesis generation about family relations and risk to children to purposeful, actionable conversations with families: the move from reflection to action. This paper supports a small but growing body of evidence about the fundamental characteristics of successful or effective supervision within children and families social work

Why does systemic supervision support practitioners' practice more effectively with children and families?

The importance of supervision for social work practice is widely accepted. This paper focuses on one type of supervision: systemic group supervision or “systemic supervision”. Systemic social work practice is generally a group-based, multi-disciplinary model of service delivery that aims to work therapeutically with the whole family. Central to this model is the use of systemically-informed group supervision. This has been shown to impact positively on the quality of direct practice with families, but what is it about this type of supervision that supports frontline practitioners to practice more skillfully? This paper is based on interviews with 49 frontline staff across five children’s services departments in the UK. It identifies the key features of systemic supervision and explores why workers think that developing shared understandings of risk to children supports them to intervene more effectively with families in contact with children’s services. These findings contribute to a growing body of knowledge about the practice shaping function of supervision within child and family social work

Landscape approaches for ecosystem management in Mediterranean Islands

This book presents a series of essays, drawing on the twm concepts of ecosystem management and landscape approaches, to elucidate and reflect on the present situation and future evolution of Mediterranean islands. This publication brings together contributions from Mediterranean individuals, non-Mediterranean individuals, islanders and non-islanders there is, after all, no geographical limit on who and what we can learn from. The essays presented here each contribute a specific perspective on the future evolution of Mediterranean islands. This book presents a series of essays, drawing on the twin concepts of ecosystem management and landscape approaches, to elucidate and reflect on the present situation and future evolution of Mediterranean islands. This publication brings together contributions from Mediterranean individuals, non-Mediterranean individuals, islanders and non-islanders; there is, after all, no geographical limit on who and what we can learn from. The essays presented here each contribute a specific perspective on the future evolution of Mediterranean islands. Following this introductory chapter, the first section of the book focuses on the contributions that can be made by the discipline of landscape ecology. loannis Vogiatzakis and Geoffrey Griffiths first explain the concepts and relevance of landscape ecology, also presenting and discussing a range of applied tools that can facilitate landscape planning in Mediterranean islands. Louis F. Cassar then reviews the 'offshoot' discipline of restoration ecology, making a strong case for offsetting the environmental damage inflicted on natural ecosystems over millennia of human occupation, with constructive efforts to effectively restore and/or rehabilitate ecosystems. The two following chapters bring the socio-economic dimension into the discussion. Godfrey Baldacchino first presents two contrasting paradigms for the development of island territories, reviewing the dual influences of ecological and economic factors, and exploring ways in which the two can be brought together in successful development strategies. Gordon Cordina and Nadia Farrugia then address the demographic dimension of development, presenting a model to explain the economic costs of high population densities on islands. The third block of chapters expands on the relevance of social and cultural dynamics to the management of Mediterranean Islands. Isil Cakcï, Nur Belkayali and Ilkden Tazebay explain the evolution of the concept of a 'cultural landscape', focusing on the challenges of managing change in landscapes with strong heritage values. The chapter concludes with a case study on the Turkish island of Gökçeada (lmbros), which is experiencing major challenges in balancing the conservation of a cultural landscape on the one hand, and the management of inevitable change, on the other. Elisabeth Conrad then discusses the role of social capital in managing the landscape resources of Mediterranean islands, reviewing the potential for this intangible social fabric to facilitate or impede the sustainable evolution of island territories. The fourth section includes four chapters, each of which addresses a different aspect relevant to policy development and implementation in Mediterranean islands. Salvino Busuttil presents an essay outlining the political influences on the management of coastal landscapes, the latter so relevant to Mediterranean island territories. The essay derives from the author's professional experience in various policy-related institutions for environmental management within the Mediterranean region. Maggie Roe then reflects on issues of landscape sustainability, focusing on the neglected aspect of intelligence. She discusses ways in which landscape research, knowledge and understanding can feed directly into frameworks for 'sustainable' landscape planning. In the subsequent chapter, Adrian Phillips takes from his substantial experience with international landscape policy, reviewing the gradual emergence of international and national landscape 'tools', to draw out lessons for application in Mediterranean islands. In the final chapter of this section, Riccardo Priore and Damiano Galla present a comprehensive discussion of the European Landscape Convention, the first international instrument to focus exclusively on landscape. The authors explain the innovative character of this convention, and discuss its potential implementation in Mediterranean islands. The publication concludes with a series of case studies, highlighting specific constraints, experiences and opportunities in different Mediterranean islands. Theano Terkenli explores the landscapes of tourism in Mediterranean islands - perhaps no other industry has played such a fundamental role in shaping the evolution of Mediterranean landscapes in recent years. The author reviews the theoretical relationship between landscape and tourism across Mediterranean islands, before focusing on the specific case of the Greek Cycladic islands. In the following chapter, Alex Camilleri, Isabella Colombini and Lorenzo Chelazzi present an in-depth review of the context and challenges being faced on a number of minor Mediterranean islands, namely those of the Tuscan archipelago (Elba, Giglio, Capraia, Montecristo, Pianosa, Gorgona and Giannutri), and Comino, the latter forming part of the Maltese archipelago. The comparison between these various islands enables an appreciation of both commonalities across these islands, as well as considerations that are specific to the context of each in dividual island. JeremyBoissevain then adopts an anthropological lens to review the cautionary tale of landscape change in Malta, exploring underlying causes of landscape destruction and limited civil engagement. In the subsequent chapter, Jala Makhzoumi outlines the richness of Mediterranean islands' rural landscapes, focusing on olive landscapes in Cyprus. Her research demonstrates the economic and ecological robustness of various olive cultivation practices, and whilst warning of several threats to such sustainable regimes, she outlines strategies for reconfiguring our approach to rural heritage, in order to integrate such assets into sustainable development strategies. Finally, Stephen Morse concludes the section with an evaluation of sustainable development indicators, and the contribution that these can make towards enhancing the management of Mediterranean island territories. He illustrates his arguments with reference to the two island states of Malta and Cyprus. To conclude, in the final chapter of this publication, we review key insights emerging from the various chapters, and summarize considerations for ecosystem management and sustainable development in Mediterranean Islands. We truly hope that this publication makes some contribution towards safeguarding the "magic' of Mediterranean islands, whilst embracing their dynamic characteristics.Published under the patronage of UNESCO and with the support of the Maltese National Commission for UNESCOpeer-reviewe
