The print block and the digital cylinder

Purpose – To consider the economic and physical impact of electronic journals on remotely stored print stock. Design/methodology/approach – A collection of print journals was used as an object for consideration. Physical and heritage aspects of the collection are examined and questions are posed regarding the wisdom of future retention in response to increased demand for electronic alternatives. Findings – Emerging trends predict a predominance of periodical literature in electronic form. The future of local remote storage for low demand printed journal collections needs to be evaluated in economic as well as cultural terms. Research limitations/implications – Based on a collection at the Boole Library, University College Cork, Ireland. Practical implications – Similar consideration should be given to collections in other regional libraries. Originality/value – Contributes to discussions on the long-term value of retaining print journal holdings.

Monasticism and its limits: rematerialising monastic space in early medieval Ireland

This thesis creates a multi-faceted archaeological context for early Irish monasticism, so as to ‘rematerialise’ a phenomenon that has been neglected by recent archaeological scholarship. Following revision of earlier models of the early Irish Church, archaeologists are now faced with redefining monasticism and distinguishing it from other diverse forms of Christian lifestyle. This research addresses this challenge, exploring the ways in which material limits can be set on the monastic phenomenon. The evidence for early Irish monasticism does not always conform to modern expectations of its character, and monastic space must be examined as culturally unique in its own right - though this thesis demonstrates that early Irish monasticism was by no means as unorthodox in its contemporary European setting as has previously been suggested. The research is informed by theories of the body, habitus and space, drawing on a wide body of archaeological, religious, sociological and anthropological thought. The data-set comprises evidences gathered through field-survey, reassessment of archaeological scholarship, historical research and cartographic research, enabling consideration of the ways in which early Irish monastics engaged with their environments. A sample of thirty-one early Irish ecclesiastical sites plus Iona forms the basis for discussion of the location and layout of monastic space, the ways in which monastics used buildings and space in their daily lives, the relationship of monasticism and material culture, the setting of mental and physical limits on monastic space and monastic bodies, and the variety of monastic lifestyles that pertained in early medieval Ireland. The study then examines the Christian landscapes of two case-studies in mid-Western Ireland in order to illustrate how monasticism functioned on the ground in these areas. As this research shows, the material complexities of early Irish monastic life are capable of archaeological definition in terms of both communal and personal lived experience.

Research and design of high-speed advanced analogue front-ends for fibre-optic transmission systems

In the last decade, we have witnessed the emergence of large, warehouse-scale data centres which have enabled new internet-based software applications such as cloud computing, search engines, social media, e-government etc. Such data centres consist of large collections of servers interconnected using short-reach (reach up to a few hundred meters) optical interconnect. Today, transceivers for these applications achieve up to 100Gb/s by multiplexing 10x 10Gb/s or 4x 25Gb/s channels. In the near future however, data centre operators have expressed a need for optical links which can support 400Gb/s up to 1Tb/s. The crucial challenge is to achieve this in the same footprint (same transceiver module) and with similar power consumption as today’s technology. Straightforward scaling of the currently used space or wavelength division multiplexing may be difficult to achieve: indeed a 1Tb/s transceiver would require integration of 40 VCSELs (vertical cavity surface emitting laser diode, widely used for short‐reach optical interconnect), 40 photodiodes and the electronics operating at 25Gb/s in the same module as today’s 100Gb/s transceiver. Pushing the bit rate on such links beyond today’s commercially available 100Gb/s/fibre will require new generations of VCSELs and their driver and receiver electronics. This work looks into a number of state‐of-the-art technologies and investigates their performance restraints and recommends different set of designs, specifically targeting multilevel modulation formats. Several methods to extend the bandwidth using deep submicron (65nm and 28nm) CMOS technology are explored in this work, while also maintaining a focus upon reducing power consumption and chip area. The techniques used were pre-emphasis in rising and falling edges of the signal and bandwidth extensions by inductive peaking and different local feedback techniques. These techniques have been applied to a transmitter and receiver developed for advanced modulation formats such as PAM-4 (4 level pulse amplitude modulation). Such modulation format can increase the throughput per individual channel, which helps to overcome the challenges mentioned above to realize 400Gb/s to 1Tb/s transceivers.

Between respectability and disgrace: schismogenesis and the regeneration of inequality, stigma and social exclusion in Limerick

The thesis examines cultural processes underpinning the emergence, institutionalisation and reproduction of class boundaries in Limerick city. The research aims to bring a new understanding to the contemporary context of the city’s urban regeneration programme. Acknowledging and recognising other contemporary studies of division and exclusion, the thesis creates a distinctive approach which focuses on uncovering the cultural roots of inequality, educational disadvantage, stigma and social exclusion and the dynamics of their social reproduction. Using Bateson’s concept of schismogenesis (1953), the thesis looks to the persistent, but fragmented culture of community and develops a heuristic ‘symbolic order of the city’. This is defined as “…a cultural structure, the meaning making aspect of hierarchy, the categorical structures of world understanding, the way Limerick people understand themselves, their local and larger world” (p. 37). This provides a very different departure point for exploring the basis for urban regeneration in Limerick (and everywhere). The central argument is that if we want to understand the present (multiple) crises in Limerick we need to understand the historical, anthropological and recursive processes underpinning ‘generalised patterns of rivalry and conflict’. In addition to exploring the historical roots of status and stigma in Limerick, the thesis explores the mythopoesis of persistent, recurrent narratives and labels that mark the boundaries of the city’s identities. The thesis examines the cultural and social function of ‘slagging’ as a vernacular and highly particularised form of ironic, ritualised and, often, ‘cruel’ medium of communication (often exclusion). This is combined with an etymology of the vocabulary of Limerick slang and its mythological base. By tracing the origins of many normalised patterns of Limerick speech ‘sayings’, which have long since forgotten their roots, the thesis demonstrates how they perform a significant contemporary function in maintaining and reinforcing symbolic mechanisms of inclusion/exclusion. The thesis combines historical and archival data with biographical interviews, ethnographic data married to a deep historical hermeneutic analysis of this political community.

A cultural study on communication and technology with specific reference to media in China

This dissertation examines the role of communications technology in social change. It examines secondary data on contemporary China arguing that many interpretations of events in China are unsuitable at best and at worst conceptually damages our understanding of social change in China. This is especially the case in media studies under the ‘democratic framework’. It proposes that there is an alternative framework in studying the media and social change. This alternative conceptual framework is termed a zone of interpretative development offering a means by which to discuss events that take place in a mediated environment. Taking a theoretical foundation using the philosophy of Mikhail Bakhtin this dissertation develops a platform with which to understand communication technology from an anthropological perspective. Three media events from contemporary China are examined. The first examines the Democracy Wall event and the implications of using a public sphere framework. The second case examines the phenomenon of the Grass Mud Horse, a symbol that has gained popular purchase as a humorous expression of political dissatisfaction and develops the problems seen in the first case but with some solutions. Using a modification of Lev Vygotskiĭ’s zone of proximal development this symbol is understood as an expression of the collective recognition of a shared experience. In the second example from the popular TV talent show contests in China further expressions of collective experience are introduced. With the evidence from these media events in contemporary China this dissertation proposes that we can understand certain modes of communication as occurring in a zone of interpretative development. This proposed anthropological feature of social change via communication and technology can fruitfully describe meaning-formation in society via the expression and recognition of shared experiences.
