Improving data forwarding in mobile social networks with infrastructure support: a space-crossing community approach

In this paper, we study two tightly coupled issues: space-crossing community detection and its influence on data forwarding in Mobile Social Networks (MSNs) by taking the hybrid underlying networks with infrastructure support into consideration. The hybrid underlying network is composed of large numbers of mobile users and a small portion of Access Points (APs). Because APs can facilitate the communication among long-distance nodes, the concept of physical proximity community can be extended to be one across the geographical space. In this work, we first investigate a space-crossing community detection method for MSNs. Based on the detection results, we design a novel data forwarding algorithm SAAS (Social Attraction and AP Spreading), and show how to exploit the space-crossing communities to improve the data forwarding efficiency. We evaluate our SAAS algorithm on real-life data from MIT Reality Mining and University of Illinois Movement (UIM). Results show that space-crossing community plays a positive role in data forwarding in MSNs in terms of delivery ratio and delay. Based on this new type of community, SAAS achieves a better performance than existing social community-based data forwarding algorithms in practice, including Bubble Rap and Nguyen's Routing algorithms. © 2014 IEEE.

Appropriate choice of aggregation operators in fuzzy decision support systems

Fuzzy logic provides a mathematical formalism for a unified treatment of vagueness and imprecision that are ever present in decision support and expert systems in many areas. The choice of aggregation operators is crucial to the behavior of the system that is intended to mimic human decision making. This paper discusses how aggregation operators can be selected and adjusted to fit empirical data—a series of test cases. Both parametric and nonparametric regression are considered and compared. A practical application of the proposed methods to electronic implementation of clinical guidelines is presented

The initiation and administration of drugs for advanced life support by critical care nurses in the absence of a medical practitioner

Current legislation does not permit the administration of first line resuscitation medications by suitably qualified Division 1 registered nurses (RNs) in the absence of a medical officer. This omission by the Drugs,  Poisons and Controlled Substances Act 1981 (Vic) and the Drugs, Poisons and The Controlled Substances Regulations 1995 (Vic) leaves many critical care nurses in a vulnerable legal position.

The primary aim of this study was to gauge the view of critical care nurses with respect to lobbying for change to the current legislation. In addition, the study aimed to explore and describe the educational preparation, practice perceptions and experiences of RNs working in critical care regarding cardiopulmonary resuscitation and the administration of first line advanced life support (ALS) medications in the absence of a medical officer. It was anticipated that data collected would demonstrate some of the dilemmas associated with the initiation and administration of ALS medications for practising critical care nurses and could be used to inform controlling bodies in order for them to gain an appreciation of the issues facing critical care nurses during resuscitation.

A mailout survey was sent to all members of the Victorian Branch of the Australian College of Critical Care Nurses (ACCCN). The results showed that the majority of nurses underwent an annual ALS assessment and had current ALS accreditation. Nurses indicated that they felt educationally prepared and were confident to manage cardiopulmonary resuscitation without a medical officer; indeed, the majority had done so. The differences in practice issues for metropolitan, regional and rural nurses were highlighted. There is therefore clear evidence to suggest that legislative amendments are appropriate and necessary, given the time critical nature of cardiopulmonary arrest. There was overwhelming support for ACCCN Vic. Ltd to lobby the Victorian government for changes to the law.

Exploring creativity support systems for the NE"X"T generation

This paper explores the implementation of a creativity support system for tertiary students studying games design and development at Deakin University, Victoria, Australia. The students at the centre of this study are the ‘next’ generation of learners and are often called the net generation because of their pre-imposed affinity for all things ‘online’. The creativity support system for the games students is designed within a ‘whole’ systems context. Focusing on only one tool to augment a person’s creativity does not take into consideration social factors that are pertinent on a person ability to grow their creative behaviours. This study will present a set of factors that each creativity support system should employ to facilitate creative abilities within people, with particular focus on how social activities help to enhance creativity.

Fuzzy logic in clinical practice decision support systems

Computerized clinical guidelines can provide significant benefits to health outcomes and costs, however, their effective implementation presents significant problems. Vagueness and ambiguity inherent in natural (textual) clinical guidelines is not readily amenable to formulating automated alerts or advice. Fuzzy logic allows us to formalize the treatment of vagueness in a decision support architecture. This paper discusses sources of fuzziness in clinical practice guidelines. We consider how fuzzy logic can be applied and give a set of heuristics for the clinical guideline knowledge engineer for addressing uncertainty in practice guidelines. We describe the specific applicability of fuzzy logic to the decision support behavior of Care Plan On-Line, an intranet-based chronic care planning system for General Practitioners.

Exploring creativity support systems for the Ne"X"t generation

This paper explores the implementation of a creativity support system (CSS) for tertiary students studying Games Design and Development at Deakin University, Victoria, Australia. The students at the centre of this study are the ‘next’ generation of learners and are often called the Internet generation because of their pre-imposed for ‘online’ and being ‘connected’. The CSS for the games students is designed within a context that encompasses a ‘whole’ system, as focusing on only one component to augment a person’s creativity does not take into consideration the multitude of factors, for example social factors, that are pertinent on a person ability to grow their creative behaviours. This study will present a set of factors that each CSS should employ to facilitate creative abilities within people, with particular focus on how social activities help to enhance creativity.

Assessing advanced life support (ALS) competence: Victorian practices

Advanced life support (ALS) assessments are performed to assess nurses’ abilities to recognize cardiac arrest events, and appropriately manage patients according to resuscitation guidelines. Although there is evidence for conducting assessments after initial ALS education, there is little evidence to guide educators about ongoing assessments in terms of methods, format and frequency.

The aim of this study was to determine methods used by educators to assess ALS skills and knowledge for nurses in Victorian intensive care units. This descriptive study used telephone interviews to collect data. Data were analysed using content analysis. Twenty intensive care educators participated in this study. Thirteen educators (65%) were employed in public hospitals, and 7 educators (35%) worked in private hospitals across 12 Level 3 (60%) and 8 Level 2 (40%) intensive care units.

Results showed all educators used scenarios to assess ALS skills, with 12 educators (60%) including an additional theoretical test. There was variability in ALS assessment frequency, assessment timing in relation to initial/ongoing education, person performing the assessment, and the assessor/participant ratio. Nineteen educators (95%) reported ALS skill competency assessments occurred annually; 1 educator (5%) reported assessments occurred every 2 years. Assessments were conducted during a designated month (n = 10), numerous times throughout the year (n = 8), or on nurses’ employment anniversaries (n = 2). All educators reported many nurses avoided undertaking assessments.

Variability in ongoing ALS assessment methods was evident in Victorian intensive care units with some units applying evidence-based practices. Consideration should be given to the purposes and methods of conducting annual ALS assessments to ensure resources and strategies are directed appropriately. To encourage nurses to retain ALS skills and knowledge, regular practices are recommended as an alternative to assessments. However, further research is required to support this notion.

Comparison of two modes of delivery of first aid training including basic life support

Aims: Flexible-learning first aid courses are increasingly common due to reduced classroom contact time. This study compared retention of first aid knowledge and basic life support (BLS) skills three months after a two-day, classroom-based first aid course (STD) to one utilizing on-line theory learning at home followed by one day of classroom training (FLEX).
Methods: In this prospective randomized controlled trial, 256 participants with internet access and no first aid related training for at least five years were randomly allocated to a STD or FLEX course. Assessment was conducted immediately after training and again three months later. Each participant was allocated a theory and a BLS score, which were summed and averaged to create an equally-weighted ‘combined score’
of first aid knowledge and skills.
Results: There was no significant difference in theory scores between the STD and FLEX groups immediately after training and after three months. STD participants had significantly higher BLS scores immediately after training (p = 0.001) and three months later (p = 0.046). Males had significantly higher BLS scores after training (p < 0.001), but not three months later (p = 0.02). Participants older than 46 years had significantly lower BLS scores than younger participants (p < 0.001). There was no significant difference in combined scores between the STD and FLEX groups or between genders, education or age groups either immediately after training or three months later.
Conclusion: After replacing one day of classroom-based training with on-line theory training, there was no significant difference in the first aid competencies of the study population, as measured by an equallyweighted
combined score of basic life support and first aid theory.

Decision support in interest based negotiation support systems: the AssetDivider system

Negotiation Support Systems (NSS) model the process of negotiation from basic template support to more sophisticated decision making support. The authors attempt to develop systems capable of decision support by suggesting possible solutions for the given dispute. Current Negotiation Support Systems primarily rely upon mathematical optimisation techniques and often ignore heuristics and other methods derived from practice. This chapter discusses the technology of several negotiation support systems in family law developed in their laboratory based on data collected and methods derived from practise. The chapter explores similarities and differences between systems the authors have created and demonstrates their latest development, AssetDivider.

Managing negotiation knowledge with the goal of developing negotiation decision support systems

While Information Technology has been used to support negotiation there is little research in the domain of knowledge management in legal negotiation. In this paper we discuss the nature of negotiation knowledge and how such knowledge can be utilized to construct negotiation decision support systems. We conduct an in-depth examination of the notion of a BATNA (Best Alternative to a Negotiated Agreement) and given a useful BATNA, how we can use issue and preference elicitation and compensation and trade-off strategies to provide negotiation decision support. We conclude by indicating how current negotiation support systems can be extended to support Online Dispute Resolution and haw we can extend the Family_Winner system in light of the need to more adequately manage negotiation knowledge.

Trade-off manipulations in the development of negotiation decision support systems

Our model of negotiation for constructing Negotiation Decision Support Systems is based upon Principled Negotiation and uses trade-off manipulations in order to provide decision support. A resulting system, Family_Winner, was constructed using several information systems techniques. Trade-off Maps (a variant of Constraint Diagrams) are used to represent trade-off opportunities, while an empirically derived formula calculates the amount of compensation given to the ratings of issues remaining in dispute. The Issue Decomposition Hierarchy embedded in the system allows for the incorporation of sub-issues. Family_Winner was originally built for use in Australian Family Law. We believe our model can be extended for use in various other domains.

Family_Winner has been evaluated in the areas of industrial relations, international disputation and company disputes. Results from our evaluation suggest the system works satisfactorily in these domains. We conclude this paper by describing future projects that will develop and extend Family_Winner's functions and applicability.

Developing negotiation decision support systems that support mediators : a case study of the Family_Winner system

Negotiation Support Systems have traditionally modelled the process of negotiation. They often rely on mathematical optimisation techniques and ignore heuristics and other methods derived from practice. Our goal is to develop systems capable of decision support to help resolve a given dispute. A system we have constructed, Family_Winner, uses empirical evidence to dynamically modify initial preferences throughout the negotiation process. It sequentially allocates issues using trade-offs and compensation opportunities inherent in the dispute.

Facilitating best practice : transferring the lessons of the Clinical Support Systems program

The Clinical Support Systems Program (CSSP) includes the management of clinical practice using clinical and consumer pathways, outcome and performance indicators, clinical measurement and review in a continuous improvement cycle using the best available extant evidence. The Royal Australasian College of Physicians is testing the CSSP model through four consortia around Australia. There are 17 project sites in three States. The funded projects address major clinical problems including congestive heart failure and acute coronary syndromes, acute stroke management, and colorectal cancer care. There is some early evidence of the CSSP influencing change in areas beyond the bounds of the project settings and the College has developed a plan to promote wider adoption of best practice. This approach recognises the College’s role in providing Fellows with the practical tools of quality improvement, the means to collect data and compare their practice to other clinicians, while traversing the appropriate educational framework.
