Shaping the criminal justice system: the role of those supported by Criminal Justice Service

In Scotland, the development and delivery ofpersonalised social work services has been part of a wider public service reform agenda, building on Changing lives: report of the 21st century review of social work (Scottish Executive, 2006). This agenda has focused on harnessing the strengths, predilections, networks and capacities of those supported by services, to inform the design and delivery of services. To date, the place of criminal justice in this reform agenda has received comparatively limited attention (Weaver, 2011). This Insight focuses on the issue of involving those who have offended in shaping the criminal justice system, exploring the different models of involvement, the effectiveness of different approaches and the implications for Criminal Justice Social Work services

XTP for the NASA space station

The NASA Space Station is a truly international effort; therefore, its communications systems must conform to established international standards. Thus, NASA is requiring that each network-interface unit implement a full suite of ISO protocols. However, NASA is understandably concerned that a full ISO stack will not deliver performance consistent with the real-time demands of Space Station control systems. Therefore, as a research project, the suitability of the Xpress transfer protocol (XTP) is investigated along side a full ISO stack. The initial plans for implementing XTP and comparing its performance to ISO TP4 are described

Discursive manoeuvres and hegemonic recuperations in New Zealand documentary representations of domestic violence

This paper examines three television documentaries--entitled Not Just a Domestic (1994), Not Just a Domestic: The Update (1994), and Picking Up the Pieces (1996)--that together formed part of the New Zealand police ‘Family Violence’ media campaign. Through a Foucauldian, feminist poststructuralist discourse analysis, the paper examines how these texts assert and privilege particular understandings of domestic violence, its causes, effects and possible solutions. The analysis illustrates the way in which five discursive explanations of domestic violence--those of medical pathology, romantic expressive tension, liberal humanist instrumentalism, tabula rasa learning and socio-systematic discourse--are articulated and hierarchically organised within these documentaries, and considers the potential hegemonic effects of each text’s discursive negotiations. It is argued that the centrality of personal ‘case studies’ and the testimonies of both battered women and formerly violent men work to privilege individualistic rather than socio-political explanations of domestic violence. Additionally, the inclusion of extensive ‘survivor speech’ means that women are frequently asked to explain and rationalize their actions as ‘victims’ of domestic violence, while fewer demands are placed on male perpetrators to account for their violent behaviour. Consequently, the documentaries leave the issue of male abuse of power largely unchallenged, and in this way ultimately affirm patriarchal hegemonic interests

Issues in designing transport layer multicast facilities

Multicasting denotes a facility in a communications system for providing efficient delivery from a message's source to some well-defined set of locations using a single logical address. While modem network hardware supports multidestination delivery, first generation Transport Layer protocols (e.g., the DoD Transmission Control Protocol (TCP) (15) and ISO TP-4 (41)) did not anticipate the changes over the past decade in underlying network hardware, transmission speeds, and communication patterns that have enabled and driven the interest in reliable multicast. Much recent research has focused on integrating the underlying hardware multicast capability with the reliable services of Transport Layer protocols. Here, we explore the communication issues surrounding the design of such a reliable multicast mechanism. Approaches and solutions from the literature are discussed, and four experimental Transport Layer protocols that incorporate reliable multicast are examined

A proposed group management scheme for XTP multicast

The purpose of a group management scheme is to enable its associated transfer layer protocol to be responsive to user determined reliability requirements for multicasting. Group management (GM) must assist the client process in coordinating multicast group membership, allow the user to express the subset of the multicast group that a particular multicast distribution must reach in order to be successful (reliable), and provide the transfer layer protocol with the group membership information necessary to guarantee delivery to this subset. GM provides services and mechanisms that respond to the need of the client process or process level management protocols to coordinate, modify, and determine attributes of the multicast group, especially membership. XTP GM provides a link between process groups and their multicast groups by maintaining a group membership database that identifies members in a name space understood by the underlying transfer layer protocol. Other attributes of the multicast group useful to both the client process and the data transfer protocol may be stored in the database. Examples include the relative dispersion, most recent update, and default delivery parameters of a group

An implementation and analysis of the Abstract Syntax Notation One and the basic encoding rules

The details of abstract syntax notation one standard (ASN.1) and the basic encoding rules standard (BER) that collectively solve the problem of data transfer across incompatible host environments are presented, and a compiler that was built to automate their use is described. Experiences with this compiler are also discussed which provide a quantitative analysis of the performance costs associated with the application of these standards. An evaluation is offered as to how well suited ASN.1 and BER are in solving the common data representation problem
