Policy-based techniques for self-managing parallel applications

This paper presents an empirical investigation of policy-based self-management techniques for parallel applications executing in loosely-coupled environments. The dynamic and heterogeneous nature of these environments is discussed and the special considerations for parallel applications are identified. An adaptive strategy for the run-time deployment of tasks of parallel applications is presented. The strategy is based on embedding numerous policies which are informed by contextual and environmental inputs. The policies govern various aspects of behaviour, enhancing flexibility so that the goals of efficiency and performance are achieved despite high levels of environmental variability. A prototype self-managing parallel application is used as a vehicle to explore the feasibility and benefits of the strategy. In particular, several aspects of stability are investigated. The implementation and behaviour of three policies are discussed and sample results examined.

Managing digital libraries using semantic web technologies

The aim of this work is to improve retrieval and navigation services on bibliographic data held in digital libraries. This paper presents the design and implementation of OntoBib¸ an ontology-based bibliographic database system that adopts ontology-driven search in its retrieval. The presented work exemplifies how a digital library of bibliographic data can be managed using Semantic Web technologies and how utilizing the domain specific knowledge improves both search efficiency and navigation of web information and document retrieval.

Flexible and robust run-time configuration for self-managing systems

This paper describes a methodology for deploying flexible dynamic configuration into embedded systems whilst preserving the reliability advantages of static systems. The methodology is based on the concept of decision points (DP) which are strategically placed to achieve fine-grained distribution of self-management logic to meet application-specific requirements. DP logic can be changed easily, and independently of the host component, enabling self-management behavior to be deferred beyond the point of system deployment. A transparent Dynamic Wrapper mechanism (DW) automatically detects and handles problems arising from the evaluation of self-management logic within each DP and ensures that the dynamic aspects of the system collapse down to statically defined default behavior to ensure safety and correctness despite failures. Dynamic context management contributes to flexibility, and removes the need for design-time binding of context providers and consumers, thus facilitating run-time composition and incremental component upgrade.

A run-time configurable software architecture for self-managing systems

This paper describes a highly flexible component architecture, primarily designed for automotive control systems, that supports distributed dynamically- configurable context-aware behaviour. The architecture enforces a separation of design-time and run-time concerns, enabling almost all decisions concerning runtime composition and adaptation to be deferred beyond deployment. Dynamic context management contributes to flexibility. The architecture is extensible, and can embed potentially many different self-management decision technologies simultaneously. The mechanism that implements the run-time configuration has been designed to be very robust, automatically and silently handling problems arising from the evaluation of self- management logic and ensuring that in the worst case the dynamic aspects of the system collapse down to static behavior in totally predictable ways.

‘The Pinocchio Effect’ – when managing the brand creation process, across cultures

In global marketing and international management, the fields of Branding and Culture are well discussed as separate disciplines; within both academia and industry. However, there appears to be limited supporting literature, examining brands and culture as a collective discipline. In addition, environmental factors such as ethnicity, nationality and religion are also seen to play a significant role. This in itself adds to the challenges encountered, by those looking to critically apply learning and frameworks, to any information gathered. In the first instance, this paper tries to bring aspects together from Branding and Culture and in doing so, aims to find linkages between the two. The main purpose of this paper is to distil current brand thinking and explore what impact cross-cultural, cross-national, and ethnic interactions have on a brand’s creation. The position of the authors is that without further understanding in this field, a brand will experience what has been termed by them as the ‘Pinocchio Effect’. Pinocchio was a puppet who longed to become a real human being; but sadly encountered difficulties. The conclusion presented is that the critical long-term success of a brand lies in three areas: how it is created; the subsequent associated perceptions; and more specifically in the reality of the relationships that it enjoys. Collectively these processes necessitate an appraisal of connecting strategic management procedures and thinking. Finally, this paper looks into proposing future methods for brand evaluation and strategic management. The aim is to stimulate further thinking in a field; which transcends national, ethnic and cultural boundaries - in the interests of developing new insight, and to provide a platform for marketers to develop more effective communications.

Managing alcohol related aggression in the emergency department (Part II)

Violence in the emergency department (ED) is a global problem. In our first paper, we highlighted the potential psychological effects of alcohol intoxication, the literatures discussion of alcohol related violence in the emergency department and the importance of developing positive nurse/service user relationships. In this second paper, we discuss personal and organisational strategies clinical nursing staff may consider appropriate to minimise the risk of assault when caring for service users projecting alcohol related aggression.

Managing alcohol related aggression in the emergency department (Part 1)

Internationally, violence in the emergency department (ED) is of a constant concern to emergency practitioners. Frequently, both original research papers and anecdotal reports emphasise the phenomenon of alcohol related aggression in the ED. In this first paper, we highlight the literatures discussion of alcohol related violence in the emergency department and the potential psychological effects of alcohol intoxication. In the second we offer personal and organisational strategies clinical nursing staff may consider appropriate to minimise the risk of assault when caring for service users projecting alcohol related aggression.

Managing the supply side for product development in China: a Guanxi network approach

Based on the IMP research tradition this paper regards relationships and networks as key issues in the product development and supply management agenda. Within business networks, co-development is only possible to be analysed when emphasis is placed on interdependences and interactive relationships. Co-development usually implies close relationships that allow companies to rely on each other's resources. Close relationships imply interdependences, which may improve companies' technical and product development. By looking at the actual interactions - between a UK company and its Chinese suppliers - that led to an innovative solution and a successful product launch, evolving relationship patterns are identified and analysed in a case study. Both the literature review and case study findings highlight the importance of the 'guanxi' concept (meaning interpersonal relationships in Mandarin) when analysing business-to-business networks in China. Hence, it is suggested that guanxi-based thinking and acting should be incorporated into the interaction model when considering business networking that embrace China. 'Guanxi' broadens the validity of the interaction model, in terms of geographical proximity, and deepens its theoretical base. The case study provides valuable insights for supply management under a product development context in China. In practice, the main point of interest is that Chinese suppliers are important 'resource' providers as well as 'network' providers. Hence, it is suggested that guanxi practice should be reflected into theoretical developments.

Managing the risk of parenting

The aim of parents is to enable their children to become autonomous individuals capable of participating fully in the culture in which they live (Korbin 1997). Furthermore, the quality of parenting is reflected in an adult’s ability to recognize and adequately meet a child’s needs in a developmentally and emotionally appropriate manner (Donald & Jureidini 2004).Within contemporary society however, parents are faced with the tensions of providing boundaries whilst affording children rights. This in itself brings risks and a common thread that runs through approaches to parenting is the attempt to define a threshold of acceptable parenting. Above the threshold and a parent is good enough and below is not good enough. This paper will consider what the minimum requirements are and explore different dimensions of parenting. The concept of good enough parenting will be revisited in relation to risks that parents have to take, within the context of contemporary policy related to improving outcomes for children as enshrined in the Every Child Matters: Change for Children Agendas (Department for Education and skills 2003). The current dominance of a risk management approach to safeguarding children will be addressed within the context of a ‘risk society’ and the importance of the safety and well-being of the child will be examined It will be suggested that we need to achieve a better balance of ensuring the safety of the child, meeting the child's developmental needs, and supporting family functioning if we are to help parents manage the risks.
