The observant mind:self-awareness of attentional status

Visual perception is dependent not only on low-level sensory input but also on high-level cognitive factors such as attention. In this paper, we sought to determine whether attentional processes can be internally monitored for the purpose of enhancing behavioural performance. To do so, we developed a novel paradigm involving an orientation discrimination task in which observers had the freedom to delay target presentation--by any amount required--until they judged their attentional focus to be complete. Our results show that discrimination performance is significantly improved when individuals self-monitor their level of visual attention and respond only when they perceive it to be maximal. Although target delay times varied widely from trial-to-trial (range 860 ms-12.84 s), we show that their distribution is Gaussian when plotted on a reciprocal latency scale. We further show that the neural basis of the delay times for judging attentional status is well explained by a linear rise-to-threshold model. We conclude that attentional mechanisms can be self-monitored for the purpose of enhancing human decision-making processes, and that the neural basis of such processes can be understood in terms of a simple, yet broadly applicable, linear rise-to-threshold model.

The relationship between self-awareness of attentional status, behavioral performance and oscillatory brain rhythms

High-level cognitive factors, including self-awareness, are believed to play an important role in human visual perception. The principal aim of this study was to determine whether oscillatory brain rhythms play a role in the neural processes involved in self-monitoring attentional status. To do so we measured cortical activity using magnetoencephalography (MEG) and functional magnetic resonance imaging (fMRI) while participants were asked to self-monitor their internal status, only initiating the presentation of a stimulus when they perceived their attentional focus to be maximal. We employed a hierarchical Bayesian method that uses fMRI results as soft-constrained spatial information to solve the MEG inverse problem, allowing us to estimate cortical currents in the order of millimeters and milliseconds. Our results show that, during self-monitoring of internal status, there was a sustained decrease in power within the 7-13 Hz (alpha) range in the rostral cingulate motor area (rCMA) on the human medial wall, beginning approximately 430 msec after the trial start (p < 0.05, FDR corrected). We also show that gamma-band power (41-47 Hz) within this area was positively correlated with task performance from 40-640 msec after the trial start (r = 0.71, p < 0.05). We conclude: (1) the rCMA is involved in processes governing self-monitoring of internal status; and (2) the qualitative differences between alpha and gamma activity are reflective of their different roles in self-monitoring internal states. We suggest that alpha suppression may reflect a strengthening of top-down interareal connections, while a positive correlation between gamma activity and task performance indicates that gamma may play an important role in guiding visuomotor behavior. © 2013 Yamagishi et al.

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.

Real options and multinational investments : an empirical study of risk, performance and organisational awareness

DUE TO COPYRIGHT RESTRICTIONS ONLY AVAILABLE FOR CONSULTATION AT ASTON UNIVERSITY LIBRARY AND INFORMATION SERVICES WITH PRIOR ARRANGEMENT This thesis is a cross-disciplinary study of the empirical impact of real options theory in the fields of decision sciences and performance management. Borrowing from the economics, strategy and operations research literature, the research examines the risk and performance implications of real options in firms’ strategic investments and multinational operations. An emphasis is placed on the flexibility potential and competitive advantage of multinational corporations to explore the extent to which real options analysis can be classified as best practice in management research. Using a combination of qualitative and quantitative techniques the evidence suggests that, if real options are explored and exploited appropriately, real options management can result in superior performance for multinational companies. The qualitative findings give an overview of the practical advantages and disadvantages of real options and the statistical results reveal that firms which have developed a high awareness of their real options are, as predicted by the theory, able to reduce their downside risk and increase profits through flexibility, organisational slack and multinationality. Although real options awareness does not systematically guarantee higher returns from operations, supplementary findings indicate that firms with evidence of significant investments in the acquisition of real options knowledge tend to outperform competitors which are unaware of their real options. There are three contributions of this research. First, it extends the real options and capacity planning literature to path-dependent contingent-claims analysis to underline the benefits of average type options in capacity allocation. Second, it is thought to be the first to explicitly examine the performance effects of real options on a sample of firms which have developed partial capabilities in real options analysis suggesting that real options diffusion can be key to value creation. Third, it builds a new decision-aiding framework to facilitate the use of real options in projects appraisal and strategic planning.

The growth and awareness of health and safety at work, 1780-1900

This thesis examines the growth and awareness of health and safety at work between 1780 and 1900. In this period the hazards at work were increased by the intensification of production brought about by the Industrial Revolution, and new risks to health arose from the wider range of toxic substances in use by manufacturing industry. There is discussion in the thesis of the extent to which the problems were identified in an age of short life expectancy and limited medical knowledge. The sources studied have been largely medical, governmental, trade and press reports. The emphasis is on the first effects seen and recommendations made, and where possible, the extent of the problem and the effectiveness of any preventative measures adopted and examined. There is discussion of the growing involvement of the Government in industrial health and safety. The subject is viewed in the light of modern thinking on industrial health but uses a classification appropriate to historical resources. Psychological and minor afflictions, neglected in the 19th century, are not considered. The available literature is reviewed in each section. Three detailed case studies conclude the thesis, two on the notoriously dangerous occupations of metal grinding and pottery, and one on occupational eye injuries. Each study is based on a different type of source material. The thesis overall shows that there was extensive concern for health and safety at work, but no systematic approach and only ad hoc implementation of preventative measures; and that the rate at which conditions improved varied between different industries and different categories of workers . However, some modern principles of health and safety at work can be seen emerging, and the period laid the necessary medical, technical and legal foundations for developments in the present century.

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.

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.

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.

Sustainable purchasing practices:an investigation into current industry awareness and practice

This research study illustrates the importance of sustainable purchasing practices for organizations in the U.S. distribution industry and answers several important questions: what is the current awareness of U.S. organizations regarding sustainable purchasing practices; to what extent are U.S. organizations evaluating, selecting, and retaining suppliers based upon sustainable purchasing practices; and to what extent are sustainable purchasing practices being implemented by the U.S. organizations under study? With an ever increasing global economy, is it critically important for organizations to put in place sustainability practices; the biggest impact organizations can make is often in an organization’s purchasing department. The researcher begins by explaining the reasoning for conducting the research, and then builds the readers’ understanding of sustainability in a supply chain environment. It then moves to the subject of how sustainable purchasing can be an advantageous method for bringing about “triple bottom line” savings to an organization. This section is followed by the researcher’s methodology and ending results for a survey conducted to examine the current awareness and implementation of sustainable purchasing practices among U.S. plumbing, heating, cooling and piping (PHCP) distribution firms who participated in the study.
