Enhancement of user level controls in cloud databases

Industries in developed countries are moving quickly to ensure the rapid adoption of cloud computing. At this stage, several outstanding issues exist, particularly related to Service Level Agreements (SLAs), security and privacy. Consumers and businesses are willing to use cloud computing only if they can trust that their data will remain private and secure. Our review of research literature indicates the level of control that a user has on their data is directly correlated to the level of data privacy provided by the cloud service. We considered several privacy factors from the industry perspective, namely data loss, data storage location being unknown to the client, vendor lock-in, unauthorized secondary use of user's data for advertising, targeting secured backup and easy restoration. The level of user control in database models were identified according to the level of existence in these privacy factors. Finally, we focused on a novel logical model that might help to bring the level of user control of privacy in cloud databases into a higher level.

Organisational memory and the propensity to mentor

In many countries, people are retiring earlier than ever before and the retirement of the baby boom generation over the next two decades further intensifies this trend. Accompanying this phenomenon is the potential loss of organisational knowledge and memory and with it, potential loss of the organisation's competitive advantage. Organisations, while recognising that older workers possess valuable organisational memory, seem to assume these same workers will readily divest themselves of their knowledge, if given the opportunity. Furthermore, offering experienced workers the opportunity to act as a mentor to pass on their knowledge is often mentioned in the management and related literature as a way of attracting and retaining these workers. While the relationships between age and the possession of organisational memory has been supported through age's positive relationship with organisational tenure and rank, past research on mentoring reveals a negative relationship between age and willingness to mentor. Employees, especially older workers in the possession of considerable organisational memory may, or may not be willing to divulge that information to others for a number of reasons. Their willingness to act as a mentor may be constrained by awareness of possible costs involved in the mentoring relationship. This paper investigates the relationship between an individual's estimated level of organisational knowledge and memory, and their inclination to mentor others. In doing so, it considers the expected costs and benefits of mentoring. It also investigates the role of mentoring in the psychological adjustment to retirement for older individuals, and discusses the rationale for a research agenda to address these issues and the likely variables of interest. The proposed research aims to go beyond the prescription of "mentoring others" as a general panacea for utilising the skills and experience of workers while ensuring the transfer of potentially threatened knowledge within organisations, by suggesting other motivations that may be operating when employees are invited to share or volunteer their prized knowledge.

iTeach we learn via mobile apps : "a case study in a business course"

Mobile smart phones and Mobile applications (apps) can be seen as an added opportunity for education and for teachers in particular, this can be true if educational institutions are willing to enable this type of delivery mechanism. With the recent development of app technologies in today’s society and the shift towards mobile technologies (devices and applications), it seems hard to imagine better devices and tools that can grant students easy and on demand access to learning content. These smart devices and technologies are multitasking and can offer variety of educational apps that teachers and students are able to integrate into their daily learning activities and can carry with them anywhere. In this paper mobile apps and their integration in education are discussed, a case study on the use of three mobile apps (e-Lecture-Producer, Dropbox and QR Code) in an educational setting in a Business e-commerce course is described. Results and outcomes are discussed based on the results from the case study.

Editorial : Surveillance and sport

Sports represent an ideal field to explore the importance of everyday surveillance practices. The routines of preparation associated with conducting or participating in a sports mega event at international level highlight unique facets of surveillance as everyday and normalised elements of elite international or professional sports performance. While these routines do have potential individual or social costs, or are open to various forms of subversion by athletes willing to challenge the broader objectives of fair play, other forces, such as the media or formal governance reactions to a detected rule violation, provide fuel for more rigorous forms of surveillance. This spiral of surveillance permeates downwards to impact on prospective elite athletes, and outwards to impact on other forms of behaviour considered to compromise integrity or fair play. How these values mirror and intersect with norms of surveillance in everyday life is a fruitful site for on-going research and theorisation.

Reintegration: The contribution of offence, offender and respondent factors

Community attitudes toward offender reintegration, in particular sex offenders, were investigated. Findings revealed the public are more supportive of reintegrative policies than they are willing to be involved in the reintegration process. Predictors of reintegrative attitudes were also investigated with a belief in redeemability found to be the strongest predictor.

A profile of Australian adults who have discussed their posthumous organ donation wishes with family members

Next of kin who are aware of the deceased's organ donation wishes usually will honor those wishes, while next of kin who are unaware of these wishes typically withhold consent for posthumous donation. Encouraging individuals to communicate or register their organ donation wishes is therefore important. Using a sample of 409 participants, the current study sought to develop a profile of Australian adults who had communicated their organ donation wishes to family members. Christian participants and those who had a higher income were more likely to have communicated their donation wishes. Conversely, participants were less likely to have communicated their donation wishes if they were unregistered and undecided/opposed to organ donation, unregistered but willing to donate, or fearful of death. Finally, whether participants had communicated, registered, or communicated and registered their donation wishes was associated with their age, religion, attitude toward organ donation, and recall of media content about organ donation. Messages encouraging the communication of organ donation wishes to family members should therefore be targeted toward those individuals who are most likely to be receptive toward enacting this behavior.

Efficient escrow-free identity-based signature

The notion of identity-based signature scheme (IBS) has been proven useful in some scenarios where relying on the validity of the certificates is impractical. Nevertheless, one remaining inherent problem that hinders the adoption of this cryptographic primitive in practice is due to the key escrow problem, where the private key generator (PKG) can always impersonate the user in the system. In 2010, Yuen et al. proposed the notion of IBS that does not suffer from the key escrow problem. Nevertheless, their approach relies on the judge who will later blame the malicious PKG when such a dispute occurs, assuming that the PKG is willing to collaborate. Although the approach is attractive, but unfortunately it is impractical since the malicious PKG may just refuse to collaborate when such an incident happens. In this paper, we propose a new escrow-free IBS, which enjoys three main advantages, namely key escrow free, practical and very efficient. We present a generic intuition as well as an efficient instantiation. In our approach, there is no judge involvement required, as the public can determine the malicious behaviour of PKG when such an incident happens. Further, the signature size of our instantiation is only two group elements, which outperforms the existing constructions in the literature.

Experienced teachers and multiple intelligences

In the world of the Information Age, digital natives (students) are being taught by digital immigrants (experienced teachers). These digital immigrants prefer to employ a number of abilities or multiple intelligences (Gardner 1983) to learn about software that can be beneficial to their students. As experienced teachers with limited ICT exposure, they are interested in: learning how to push buttons (P), thinking how to apply software to their practice (A) and are willing to change their practice using ICT (C). This paper discusses a study of experienced teachers with limited ICT exposure and their preferred way of learning, as they PAC for the information age.

Bridging the copyright and licensing knowledge gap

Objectives: The purpose of this project was to examine the copyright and licensing knowledge gap of academic staff to identify their current understanding of, and attitudes towards, copyright, licensing and the open access movement in relation to the content they use, create, and share in their teaching and research practice. The motivation behind this study was to gather information to assist the Library in creating and providing effective information resources and training for academic staff.

Methods: An anonymous online survey was distributed to Faculty of Health academic staff at Deakin University. Seventy individuals in the Faculty of Health completed the survey.

Results: The results suggested that most of the academics have used content created by others in their teaching materials, but they are not confident about complying with copyright or licensing conditions whilst doing so. Most had not posted any of their own content online, but would generally be willing for it to be used by others, with attribution. Around half had never posted their published articles in an institutional or discipline repository, but again, would be willing for them to be used for educational purposes. Most academics have never shared their research data online, and some were very unwilling to do so - despite current pushes to broaden access to research data sets. Finally, most had never applied a Creative Commons licence to a piece of work, and over half were unaware of what rights they had retained under publishing agreements for their work. It was strongly indicated that an informational website would be very helpful in providing guidance around topics of copyright, licensing and sharing.

Conclusions: Results were largely consistent with other similar studies conducted around these topics. There is a clear role for librarians to continue providing such training and resources as the push for Open Access resources, publishing, and data only gains momentum.

A hybrid weighted aggregation method based on consistency and consensus in group decision making

A recent study in Science indicated that the confidence of a decision maker played an essential role in group decision making problems. In order to make use of the information of each individual's confidence of the current decision problem, a new hybrid weighted aggregation method to solve a group decision making peoblem is proposed in this paper. Specifically, the hybrid weight of each expert is generated by a convex combination of his/her subjective experience-based weight and objective problem-domain-based weight. The experience-based weight is derived from the expert's historical experiences and the problem-domain-based weight is characterized by the confidence degree and consensus degree of each expert's opinions in the current decision making process. Based on the hybrid weighted aggregation method, all the experts' opinions which are expressed in the form of fuzzy preference relations are consequently aggregated to obtain a collective group opinion. Some valuable properities of the proposed method are discussed. A nurse manager hiring problem in a hospital is employed to illustrate that the proposed method provides a rational and valid solution for the group decision making problem when the experts are not willing to change their initial preferences, or the cost of change is high due to time limitation.

The Legacy of Iraq: from the 2003 War to the ‘Islamic State’

In March 2003, a US-led ‘Coalition of the Willing’ launched a pre-emptive intervention against Iraq. The nine long years of military occupation that followed saw an ambitious project to turn Iraq into a liberal democracy, underpinned by free-market capitalism and constituted by a citizen body free to live in peace and prosperity. However, the Iraq war did not go to plan and the coalition were forced to withdraw all combat troops at the end of 2011, having failed to deliver on their promise of a democratic, peaceful and prosperous Iraq. The Legacy of Iraq: From the 2003 War to the ‘Islamic State’ seeks to not only reflect on this abject failure but to put forth the argument that key decisions and errors of judgment on the part of the coalition and the Iraqi political elite set in train a sequence of events that have had devastating consequences for Iraq, for the region and for the world. Today, as the nation faces perhaps its greatest challenge in the wake of the devastating advance of the Islamic State of Iraq and Syria (ISIS) and another US-led coalition undertakes renewed military action in Iraq, understanding the complex and difficult legacies of the 2003 war could not be more urgent. To ignore the legacies of the Iraq war and to deny their connection to contemporary events means that vital lessons will be ignored and the same mistakes will be made.

Patient participation in pulmonary interventions to reduce postoperative pulmonary complications following cardiac surgery.

BACKGROUND: Clinical interventions aimed at reducing the incidence of postoperative pulmonary complications necessitate patient engagement and participation in care. Patients' ability and willingness to participate in care to reduce postoperative complications is unclear. Further, nurses' facilitation of patient participation in pulmonary interventions has not been explored. OBJECTIVE: To explore patients' ability and willingness to participate in pulmonary interventions and nurses' facilitation of pulmonary interventions. DESIGN: Single institution, case study design. Multiple methods of data collection were used including preadmission (n=130) and pre-discharge (n=98) patient interviews, naturalistic observations (n=48) and nursing focus group interviews (n=2). SETTING: A cardiac surgical ward of a major metropolitan, tertiary referral hospital in Melbourne, Australia. PARTICIPANTS: One hundred and thirty patients admitted for cardiac surgery via the preadmission clinic during a 1-year period and 40 registered nurses who were part of the permanent workforce on the cardiac surgical ward. OUTCOME MEASURES: Patients' understanding of their role in pulmonary interventions and patients' preference for and reported involvement in pulmonary management. Nurses' facilitation of patients to participate in pulmonary interventions. RESULTS: Patients displayed a greater understanding of their role in pulmonary interventions after their surgical admission than they did at preadmission. While 55% of patients preferred to make decisions about deep breathing and coughing exercises, three-quarters of patients (75%) reported they made decisions about deep breathing and coughing during their surgical admission. Nurses missed opportunities to engage patients in this aspect of pulmonary management. CONCLUSIONS: Patients appear willing to take responsibility for pulmonary management in the postoperative period. Nurses could enhance patient participation in pulmonary interventions by ensuring adequate information and education is provided. Facilitation of patients' participation in their recovery is a fundamental aspect of care delivery in this context.

Initiation of trades on the Chinese stock market

The flow of orders from buyers and sellers, relative to past returns and stock characteristics, was examined in the Chinese stock market. Order imbalance (the gap between buyer-and seller-initiated trades) was found to be negatively related to long term returns. Turn of the calendar year trading provided strong indications of tax-motivated trading as well as support for the flight-to-quality hypothesis, which suggests selling in response to perceived increases in market risk.

Inflation tax in the lab: a theoretical and experimental study of competitive search equilibrium with inflation

In this paper we measure the effect of the inflation tax on economic activity and welfare within a controlled setting.To do so,we develop a model of price posting and monetary exchange with inflation and finite populations.The model,which provides a game–theoreticfoundation to Rocheteau and Wright(2005)'s competitive search monetary equilibrium, is used to derive theoretical propositions regarding the effects of inflation in thisenvironment, which we test with a laboratory experiment that closely implements the theoretical framework.We find that the inflation tax is harmful – with cash holdings, production and welfare all falling as inflation rises – and that its effect is relatively larger at low inflation rates than at higher rates.For instance,for inflation rates between 0%and5%, welfare in the two markets we consider (2[seller] 2[buyer] and 3 2) falls by roughly 1 percent for each percentage–point rise in inflation, compared with 0.4 percent over the range from 5% to 30%.Our findings lead us to conclude that the impact of the inflation tax should not be underestimated, even under low inflation.

The importance of digital literacy in the knowledge era

 Digital literacy is an essential skill in the knowledge era. This research found that occupational therapists recognise the importance of digital literacy and are willing to use digital technologies yet barriers exist. Improving digital literacy is a shared concern, to be addressed at the individual, institutional, professional and societal levels.
