Market-awareness in service-based systems

Service-based systems are applications built by composing pre-existing services. During design time and according to the specifications, a set of services is selected. Both, service providers and consumers exist in a service market that is constantly changing. Service providers continuously change their quality of services (QoS), and service consumers can update their specifications according to what the market is offering. Therefore, during runtime, the services are periodically and manually checked to verify if they still satisfy the specifications. Unfortunately, humans are overwhelmed with the degree of changes exhibited by the service market. Consequently, verification of the compliance specification and execution of the corresponding adaptations when deviations are detected cannot be carried out in a manual fashion. In this work, we propose a framework to enable online awareness of changes in the service market in both consumers and providers by representing them as active software agents. At runtime, consumer agents concretize QoS specifications according to the available market knowledge. Services agents are collectively aware of themselves and of the consumers' requests. Moreover, they can create and maintain virtual organizations to react actively to demands that come from the market. In this paper we show preliminary results that allow us to conclude that the creation and adaptation of service-based systems can be carried out by a self-organized service market system. © 2012 IEEE.

Cross country comparison of careers in logistics management in Australia and Britain

Purpose – The aim of this research was to ascertain the current roles and responsibilities of logistics managers in two countries, how they compare their situation with other managers and to identify the types of knowledge and experience that would assist them to develop their careers. Design/methodology/approach – This paper compares the results of a postal survey of 303 Australian and 161 British logistics managers. Findings – The study indicates that logistics managers in both countries share many similar experiences, responsibilities and perceptions of their career situations. They take considerable pride and satisfaction from these careers but recognise the need for continuing professional development in their present and future roles. Research limitations/implications – The research is limited to the respondents to the surveys. Further research in other countries including less well-developed economies would add to the generalisation of results. Practical implications – It is argued that for successful international supply chain management, there is a need to review both current and future provision in higher education and continuing professional development, in order to strengthen strategic competences and increase understanding of the significance of interdisciplinary awareness in global markets. Originality/value – This paper represents the first attempt to understand the roles, responsibilities, career pathways and future needs of logistics managers in the two countries. Its results should provide guidance to top managers for the future success of the logistics function in their organisations.

Self-adaptive volunteered services composition through stimulus-and time-awareness

Volunteered Service Composition (VSC) refers to the process of composing volunteered services and resources. These services are typically published to a pool of voluntary resources. Selection and composition decisions tend to encounter numerous uncertainties: service consumers and applications have little control of these services and tend to be uncertain about their level of support for the desired functionalities and non-functionalities. In this paper, we contribute to a self-awareness framework that implements two levels of awareness, Stimulus-awareness and Time-awareness. The former responds to basic changes in the environment while the latter takes into consideration the historical performance of the services. We have used volunteer service computing as an example to demonstrate the benefits that self-awareness can introduce to self-adaptation. We have compared the Stimulus-and Time-awareness approaches with a recent Ranking approach from the literature. The results show that the Time-awareness level has the advantage of satisfying higher number of requests with lower time cost.

Graduate employability, 'soft skills' versus 'hard' business knowledge:a European study

There is a growing awareness in the UK and mainland Europe of the importance of higher education to the development of a knowledge-based economy. European universities are increasingly required to produce highly mobile graduates able to respond to the ever-changing needs of the contemporary workplace. Following the Bologna Declaration (19991. 19 June 1999 . “The European Higher Education Area” (Bologna Declaration), Joint Declaration of the European Ministers of Education, Bologna, higher education across Europe has expanded rapidly. This has resulted in questions being raised about the quality of the graduate labour market and the ability of graduates to meet the needs of employers. This paper analyses graduate and employer perspectives of graduate employability in four European countries (UK, Austria, Slovenia and Romania). In doing so it adds to current debates in this area.

Separating the influences of prereading skills on early word and nonword reading

The essential first step for a beginning reader is to learn to match printed forms to phonological representations. For a new word, this is an effortful process where each grapheme must be translated individually (serial decoding). The role of phonological awareness in developing a decoding strategy is well known. We examined whether beginner readers recruit different skills depending on the nature of the words being read (familiar words vs. nonwords). Print knowledge, phoneme and rhyme awareness, rapid automatized naming (RAN), phonological short term memory (STM), nonverbal reasoning, vocabulary, auditory skills and visual attention were measured in 392 pre-readers aged 4 to 5 years. Word and nonword reading were measured 9 months later. We used structural equation modeling to examine the skills-reading relationship and modeled correlations between our two reading outcomes and among all pre-reading skills. We found that a broad range of skills were associated with reading outcomes: early print knowledge, phonological STM, phoneme awareness and RAN. Whereas all these skills were directly predictive of nonword reading, early print knowledge was the only direct predictor of word reading. Our findings suggest that beginner readers draw most heavily on their existing print knowledge to read familiar words.

Reporting and managing risk:a look at current practice at Tesco, RBS, local and central government

These case studies from CIMA highlight the need to embed risk management within more easily understood behaviours, consistent with the overall organisational culture. In each case, some form of internal audit team provides either an oversight function or acts as an expert link in that feedback loop. Frontline staff, managers and specialists should be completely aligned on risk, in part just to ensure that there is a consistency of approach. They should understand instinctively that good performance includes good risk management. Tesco has continued to thrive during the recession and remains a robust and efficient group of businesses despite the emergence of potential threats around consumer spending and the supply chain. RBS, by contrast, has suffered catastrophic and very public failures of risk management despite a large in-house function and stiff regulation of risk controls. Birmingham City Council, like all local authorities, is adapting to more commercial modes of operation and is facing diverse threats and opportunities emerging as a result of social change. And DCMS, like many other public sector organisations, has to handle an incredibly complex network of delivery partners within the context of a relatively recent overhaul of central government risk management processes. Key Findings: •Risk management is no longer solely a financial discipline, nor is it simply a concern for the internal control function. •Where organisations retain a discrete risk management cadre – often specialists at monitoring and evaluating a range of risks – their success is dependent on embedding risk awareness in the wider culture of the enterprise. •Risk management is most successful when it is explicitly linked to operational performance. •Clear leadership, specific goals, excellent influencing skills and open-mindedness to potential threats and opportunities are essential for effective risk management. •Bureaucratic processes and systems can hamper good risk management – either as a result of a ‘box-ticking mentality’ or because managers and staff believe they do not need to consider risk themselves.

Topographic visual analytics of multibeam dynamic SONAR data

This paper considers the problem of low-dimensional visualisation of very high dimensional information sources for the purpose of situation awareness in the maritime environment. In response to the requirement for human decision support aids to reduce information overload (and specifically, data amenable to inter-point relative similarity measures) appropriate to the below-water maritime domain, we are investigating a preliminary prototype topographic visualisation model. The focus of the current paper is on the mathematical problem of exploiting a relative dissimilarity representation of signals in a visual informatics mapping model, driven by real-world sonar systems. A realistic noise model is explored and incorporated into non-linear and topographic visualisation algorithms building on the approach of [9]. Concepts are illustrated using a real world dataset of 32 hydrophones monitoring a shallow-water environment in which targets are present and dynamic.

Large-scale complex IT systems

Society depends on complex IT systems created by integrating and orchestrating independently managed systems. The incredible increase in scale and complexity in them over the past decade means new software-engineering techniques are needed to help us cope with their inherent complexity. The key characteristic of these systems is that they are assembled from other systems that are independently controlled and managed. While there is increasing awareness in the software engineering community of related issues, the most relevant background work comes from systems engineering. The interacting algos that led to the Flash Crash represent an example of a coalition of systems, serving the purposes of their owners and cooperating only because they have to. The owners of the individual systems were competing finance companies that were often mutually hostile. Each system jealously guarded its own information and could change without consulting any other system.

The de-gaying and re-gaying of AIDS:contested homophobias in lesbian and gay awareness training

From the first recognition of AIDS as a disease, it was publicly conceptualized as a 'gay plague'. In response, health education and diversity training sought to counter this association claiming that AIDS is an 'equal opportunity' virus - that it can affect anyone. In this article, we analyse talk about HIV/AIDS within a data corpus of 13 tape-recorded lesbian and gay awareness training sessions. Counter to the way in which interactions are described in the lesbian and gay awareness training literature, we found that it was trainees, rather than trainers, who pursued discussions about HIV/AIDS, and who did so in order to claim the 'de-gaying' of AIDS, which they treated as representing a 'non-prejudiced' position. By contrast, and in response to trainees' insistence on de-gaying AIDS, trainers were 're-gaying' AIDS. Our analysis highlights that in these sessions - designed explicitly to counter homophobic attitudes - apparently 'factual' claims and counter-claims about infection rates and risk groups are underpinned by essentially contested definitions of what constitutes a 'homophobic' attitude. We conclude by pointing to the value of detailed analysis of talk-in-interaction for understanding professional practices, and suggest strategies for improving the pedagogic value of training.

Hospital pharmacists' awareness of a new antibiotic guideline in the UK:implications for practice

Objectives: Pharmacists play an important role in the review of local hospital guidelines. British Thoracic Society (BTS) guidelines for the management of patients with community-acquired pneumonia (CAP) were updated in 2001, and it is important that individual hospital recommendations are based upon this national guidance. The aim of this study was to identify UK Chief Pharmacists' awareness of these updated guidelines one year after their publication. Secondary aims were to identify whether pharmacists had subsequently initiated revision of institutional CAP guidelines, and what roles different professional staff had performed in this process. Method: A self-completion postal questionnaire was sent to the Chief Pharmacist (or their nominated staff) in 253 UK NHS hospitals in November 2002. This aimed to identify issues relating to their awareness of the 2001 BTS guidelines and subsequent revision of their hospital's guidelines. Results:188 questionnaires were returned (a response rate of 74%), of which 164 hospitals had local antibiotic prescribing guidelines. Respondents in 29% of these hospitals were unaware of the 2001 BTS publication and institutional guidelines had been revised in only 51% of hospitals where the Chief Pharmacist was purportedly aware of the new BTS guidance. Generally, more staff types were involved in revising guidelines than initiating revision. Conclusions:Variability existed in both Chief Pharmacists' awareness of new national guidance and subsequent review processes operating in individual hospitals. A lack of proactive reaction to new national guidance was identified in some hospitals, and it is hoped that the establishment of specialist "infectious diseases pharmacists" will facilitate the review of institutional antibiotic prescribing guidelines in the future. © Springer 2005.

Online digital special collections in English universities: promoting awareness

Cultural institutions in the UK are repositories of a wealth of historical material. The scholarly importance of such resources is at the basis of the numerous digitisation projects aimed at widening their access worldwide. The lack of national policies has left those institutions alone in engaging in dissemination activities and in raising awareness of their own online material. Of particular interest to the author are the digital special collections hosted in the English Universities. The main activities of these institutions differ from others, such as museums, archives and public libraries, as they do not have the main institutional duties of preserving and the exploiting of their holdings. This article highlights related issues and suggests some of the possible measures to effectively promote and disseminate universities’ online digital special collections.

Professionals' awareness of operational antibiotic prescribing controls in UK NHS hospitals

In recent years, there have been increasing recommendations for multidisciplinary collaboration between clinical pharmacists and medical microbiologists in an attempt to control the quality (and quantity) of antibiotic prescribing. A questionnaire addressing the utilization of antibiotic prescribing controls was sent to the chief pharmacist and medical microbiologist in UK NHS hospitals. Responses were received from both the chief pharmacist and the medical microbiologist employed in the same hospital from 83 hospitals (a 30% response rate from two independent studies). A high level of disagreement and poor awareness was identified between the interprofessional staff groups regarding the existence of antibiotic formulary (with disagreement between the two groups, or not known by one or both respondents, in 46% of the paired hospitals, N=38) and guideline documents (13%, N=11), performance of antibiotic prescribing audits (40%, N=33), and whether pharmacists (52%, N=43) and medical microbiologists (77%, N=64) monitored physician compliance with antibiotic prescribing control documents. This study has identified poor knowledge of the existence of basic antibiotic prescribing control mechanisms and the role of professional colleagues. It is suggested that there is some way to go before 'Agenda for Change' principles of flexible and collaborative roles are met. © 2004 The Hospital Infection Society. Published by Elsevier Ltd.

Real options in multinational decision-making:managerial awareness and risk implications

This paper addresses the theme of real options decision-making in multinational corporations (MNCs) and stresses the role of real options attention and managerial learning in company performance. Using a sample of 278 large MNCs with categorised degrees of managerial real options awareness, we examine the risk implications of switching options in multinational operations, and explore the extent to which the real options logic can be classified as “best practice” in decision-making and risk management. Our results reveal that MNCs which have high managerial awareness about their real options are able to reduce their downside risk through multinationality, organisational slack and other firm characteristics. This finding does not apply fully to MNCs without evidence of such an awareness. Also, although real options awareness does not systematically guarantee lower downside risk from operations, supplementary results indicate that MNCs with evidence of significant investment in the acquisition of real options knowledge tend to outperform competitors that are unaware of their real options. This suggests that if real options are explored and exploited appropriately, real options decision-making can result into superior performance for MNCs in the long-term.

An integrative approach to developing an intercultural awareness strategy in a multicultural university

Universities are increasingly diverse places; in terms of staff and students, their nationality, ethnicity and religious backgrounds. HEIs need to find ways of ensuring that this diversity adds to the life of the institution and to the development of graduates as employees in a global workplace. The paper offers a case study of one way of developing an intercultural strategy at a UK university. The university concerned has a highly multicultural and multinational staff and student population. Over many years the university has worked to celebrate and embed this diversity into the culture and values of the institution; in its learning, teaching, business operations and relationships. The university wished to develop its intercultural awareness strategy in an inspirational and vibrant way, one which was informed by research and practice. The paper proposes a new integrative approach to developing an intercultural strategy, and summarises some reflections on the process of creating the intercultural awareness strategy which may be of use to other institutions. Analysis showed that in order to make the strategy effective there had to be commitment from senior management to match innovative practices at an individual level. It is also clear that such a strategy must include formal policies and procedures, as well as more informal channels to allow people to express intercultural differences and shared values. The critical role of middle management in strategy implementation is also discussed.
