AbstractThe farmers of the Apatani tribe in Arunachal Pradesh, India have been raising a concurrent crop of fish successfully in their mountain valley rice plots for the past 40 years. They follow indigenous rice agronomy, ignoring the use of fertilizers, pesticides and even supplementary feed for the fish reared in the system. However, the yield levels of fish, ranging from 250 to 500 kg ha−1season−1, clearly support the role of other available resources within their wet rice fields. The investigation revealed that the rice itself provided the substrates for colonization and growth of periphyton. The colonized periphytic contents (1406–13513 no. cm−2 stem−1) on rice stems and other natural fish feeds within the system seem to have direct effect in this regard. The Apatani technique of rice–fish integration may be considered as one of the periphyton-based aquaculture (PBA) systems which deserve further research attention.

Periphyton is being used traditionally as rich aquatic feed for fishes throughout the countries like Cambodia, West Africa, Srilanka, India and Bangladesh. In waterlogged rice environment, it can be judiciously utilized as feed source introducing periphytophagous fish. Studies supported rice straw as suitable substrate for periphyton growth. The study of gut content of Common carp (Cyprinus carpio L.) from a periphyton-based rice-fish culture system in Apatani Plateau of Arunachal Pradesh, India showed maximum of 60 genera of microflora and fauna with periphytic in nature. The farmers from this rice-fish culture practice are gaining an average fish production of 500kg ha-1 180 day-1 without employing any supplementary feed. Better selection and determination of appropriate stocking density of periphytophagous fish in waterlogged rice-fields might extend the rice-fish culture towards a sustainable and self-substrating periphyton based aquaculture (SSPBA) practice. Keywords: Periphyton; Sustainable agriculture; Rice-fish; Self-substrating; Common carp; Apatani plateau. © 2009 JSR Publications.

Introductory Discussion

The concept of engaged scholarship, as a 'new' and participatory approach to knowledge production, has received much attention over the past decade. However, the term is clouded in ambiguity. This paper presents some introductory discussion around concepts of engaged scholarship, and then focuses in detail on a methodological case study of participatory action research as an example of engaged scholarship in practice. Discussion revolves around reflections on practice, drawing largely from recent reports on participatory democracy and the role of unversities in society.

And Gender

We discuss the important role of the feminist critique in bringing awareness to gender, childhood, and identity research, and in giving voice to the perspectives of underrepresented groups. As a case study of ancient social lives and gender, we discuss a range of Marajoara identity markers interpreted through the study of ceramic tangas (female pubic coverings) from Marajó Island in the Brazilian Amazon (A.D. 400-1400). There, tangas were made and used by women as a material representation of social position, gender, and individual identity. We argue that identity constitutes a fundamentally important aspect of archaeological research, and that the strongest case studies in identity are those that encompass a variety of gendered inferences to understand social lives of the past.

Insight Into

The purpose of this chapter is to examine the surge of identity politics and the diversification of heritage and the tensions that arise with the traditional role of national museums that are expected to support the model of a unitary national identity through their narratives and collections. Engaging with distinct patrimonies and transformations in museums checkmates stagnant notions of heritage, but in turn, these actions might also instigate resistance to change. A case study at the National Museum of Colombia will provide an insight into competing notions of heritage, which can be understood as the relics of a material past, but may also be seen as the meanings created about the past. This analysis instigates thoughts about the role that history and historians might play in the elaboration of narratives of identity.

Integral Feature

Leadership is fundamentally a social phenomenon, and a leader’s legitimacy in personal and social terms is determined partly by how effectively they incorporate the prototypical leader identity. Using the historical British officers’ mess as a case study, this article presents a conceptual examination of the function place can perform in the construction of collective leader identities and the interconnected influence shared history, materiality and social interaction can have in encouraging inclusivity in leadership. Leadership identity is an integral feature of military life which has historically drawn on complex cultural and legal traditions to underwrite the individual’s right to command. This article will argue that social places such as the officers’ mess have been utilised as a means of cultivating cohesion in the past and that they may have an application in furthering inclusive collective leader identities in the future.

The Face

Many Humanities scholars seem to have become increasingly pessimistic due to a lack of success in their efforts to be recognized as a serious player next to their science, technology, engineering, and maths (STEM) colleagues. This appears to be the result of a profound uncertainty in the self-perception of individual disciplines within the Humanities regarding their role both in academia and society. This ambiguity, not least, has its roots in their own history, which often appears as an interwoven texture of conflicting opinions. Taking a stance on the current and future role of the Humanities in general, and individual disciplines in particular thus asks for increased engagement with their own past, i.e., histories of scholarship, which are contingent on societal and political contexts. This article’s focus is on a case study from the field of Old Norse Studies. In the face of the rise of populism and nationalism in our days, Old Norse Studies, with their focus on a ‘Germanic’ past, have a special obligation to address societal challenges. The article argues for the public engagement with the histories of individual disciplines to strengthen scholarly credibility in the face of public opinion and to overcome trenches which hamper attempts at uniting Humanities experts and regaining distinct social relevance.

The factors that influence the ultimate level of success or failure of systems development projects have received considerable attention in the academic literature. However, despite the existence of a ‘best practice’ literature many projects still fail. The record of the National Health Service has been particularly poor in this respect. The research reported in this paper proposes that two additional factors; user ownership and positive user attitudes warrant further development and investigation. The current study investigated these two factors in a homogenous organizational sector, Community NHS Trusts, using a common type of information system, in order to eliminate the potentially confounding influences of sector and system. A multiple case-study design incorporating five Community Healthcare Trusts was utilized. The key results from the analysis indicated that both user ownership and positive user attitudes were important mediating variables that were crucial to the success of a CIS. In addition, it was also identified that the adoption of best practice variables had a dual role, directly influencing the level of perceived success but also facilitating the development of user ownership and positive user attitudes. These results will be of particular interest to practising IM&T managers in the NHS and also to the wider academic research community.

The study of rural settlement in Roman Britain is undergoing a period of re-evaluation and change. In the past, work has focused on the individual study sites, especially villas. Now there is an increasing interest in the exploitation of whole landscapes, with an emphasis on the people who lived in them and the ways that they exploited the resources available to them. These trends are reviewed, and a case study is presented based on the author’s fieldwork in East Yorkshire. Given that the bulk of the population of Roman Britain lived in the countryside, emphasis is placed on understanding the active role of these people in creating the culture of Roman Britain.

Abstract Previous studies have shown that many children of former Nazi perpetrators either identify with their parents by denying their atrocities, by distancing them-selves emotionally from their parents, or by acknowledging their participation in the extermination process. Through a hermeneutical case study of the narrated life story of a Euthanasia physician's daughter, a type of strategy, which we defined as pseudo-identification with the victim, is reconstructed. The results of the analysis suggest that this is a repair strategy. Putting oneself in the role of one's parents' victim provides refuge from acknowledging possible identification with Nazism and its idols, as well as identifying oneself with the real victims of one's parents. In this case, the psychological consequences of this strategy are described: The woman still suffers from extermination anxieties which block further working through of the past.
