A practical framework for data collection in wireless sensor networks

Optimizing energy consumption for extending the lifetime in wireless sensor networks is of dominant importance. Groups of autonomous robots and unmanned aerial vehicles (UAVs) acting as mobile data collectors are utilized to minimize the energy expenditure of the sensor nodes by approaching the sensors and collecting their buffers via single hop communication, rather than using multihop routing to forward the buffers to the base station. This paper models the sensor network and the mobile collectors as a system-of-systems, and defines all levels and types of interactions. A practical framework that facilitates deploying heterogeneous mobiles without prior knowledge about the sensor network is presented. Realizing the framework is done through simulation experiments and tested against several performance metrics.

A new H.E.L.P kit for teaching practical AC electronics to undergraduate distance students

An important part of educating students in electronics and electrical engineering is laboratory practicals. Providing effective practical experience to students by distance education has always been a significant challenge to the engineering educator. Deakin University has for many years taught practicals in basic digital electronics to off-campus students by means of a kit. The same students have performed related exercises in analogue electronics, which require generating and measuring AC signals, by means of either software simulations or on-campus attendance at lab classes. This year, for the first time, off-campus students are being provided with a new kit, which contains a low-cost, battery-powered AC signal generator, and an interface that allows a PC to be used as an oscilloscope. This kit allows the off-campus student further flexibility in learning basic electronics.

Practical application of the Delphi technique in a bicultural mental health nursing study in New Zealand

Background. Numerous studies have employed the Delphi technique to seek expert opinion about aspects of clinical practice. When researching literature on the Delphi technique, however, we discovered discrepancies in its application, and a lack of detail when reporting design, administration, and analysis methods. Such lack of specificity hinders the replicability and assessment of the clinical and cultural validity and reliability of Delphi studies.

Aim. The aim of this paper is to detail the practical application of the Delphi technique as a culturally and clinically valid means of accessing expert opinion on the importance of clinical criteria.

Methods. Reference is made to a bicultural New Zealand mental health nursing clinical indicator study that employed a three-round reactive Delphi survey. Equal proportions of Maori and non-Maori nurses (n = 20) and consumers (n = 10) rated the importance of 91 clinical indicator statements for the achievement of professional practice standards. Additional statements (n = 21) suggested by Delphi participants in round 1 were included in subsequent rounds. In round 2, participants explained the rating they applied to statements that had not reached consensus in round 1, and summarized responses were provided to participants in round 3. Consensus was considered to have been achieved if 85% of round 3 ratings lay within a 2-point bracket on the 5-point Likert-scale overall, or in one of the Maori nurse, non-Maori nurse, or consumer groups. A mean rating of 4·5 after round 3 was set as the importance threshold.

Findings. Consensus occurred overall on 75 statements, and within groups on another 24. Most statements (n = 86) reached the importance benchmark.

Conclusions. When rigorous methods of participant selection, group composition, participant feedback, and determination of consensus and importance are employed, the Delphi technique is a reliable, cost-effective means of obtaining and prioritizing experts judgements.

The Chihuahua sustainability practice: lots of shivering but no real action. Practical sustainability acceptance is low in German and New Zealand firms

Purpose – This paper aims to describe the extent to which corporate organizations in Germany and in New Zealand have included sustainability practices as part of their strategic planning process.

Design/methodology/approach – Current literature is reviewed to make a case for sustainability to be a driver behind corporate decision making and long-term performance. The results of surveys of several hundred firms in both Germany and New Zealand, countries with a publicly stated commitment to sustainability, are reviewed to compare the adoption rates of sustainability practices.

Findings – There is a significant difference between what firms do and what their managers think is important. Managers largely consider sustainability practices an important factor for their future careers, while firms to a large extent do not include sustainability as part of their strategic or operational planning process.

Research limitations/implications – The International Sustainability Acceptance Measurement (ISAM) collects data in several countries through local-language versions of the same online survey tool (www.worldreply.com). The findings in this report are specific only to New Zealand and Germany.

Practical implications – The paper points academics, corporate executives and sustainability fanatics to an alarming inconsistency between what is publicly reported as commitment to sustainability and what is practically achieved.

Originality/value – This paper adds value to the discussion of how sustainability practices have migrated into the operation of firms.

Reservation of important wetlands - recent experiences in conservation planning and practical implementation in Victoria

The establishment of a comprehensive, adequate and representative (CAR) reserve system is not only an objective of all States and Territories but it is an international commitment, since Australia signed the Convention on Biological Diversity. Various reviews note that Australia lacks a representative freshwater reserve system. However, there has been surprisingly little quantitative analysis on the reservation of freshwater ecosystems from which to identify the gaps or deficiencies in the reserve system.

We compared aspects of reservation in wetlands in northern Victoria before and after a major public land use investigation by the government-appointed Victorian Environmental Assessment Council, which sought specifically to recommend a CAR reserve system. Significant improvements in the reservation status for depleted and under-reserved wetland ecosystems, and improved reserve design have been recommended by the investigation. Increases in the reservation of nationally and internationally significant wetlands were also recommended. These recommendations are now under consideration by the Victorian Government.

Some of the challenges in decision-making during this investigation and their implications on wetland conservation are highlighted. The paper concludes by outlining broader policy dilemmas, decisions and debates that that require addressing in relation to developing a system of Freshwater Protected Areas in Australia.

Writing reports for court : a practical guide for psychologists working in forensic contexts

A practical strategy for discovering, evaluating and exploiting entrepreneurial opportunity : research based action guidelines

It has been argued that entrepreneurship researchers do not place sufficient emphasis on making their research findings relevant to entrepreneurs and their advisors. The paper utilises five general principles introduced by Hindle, Anderson and Gibson (2004) to convert a complex range of entrepreneurship research findings into useful action guidelines for practicing entrepreneurs. The existing research-based knowledge concerning opportunity assessment is distilled into a diagrammatic framework. This framework and a sequence of ten, plain-English questions, provides entrepreneurs and SME operators with a strategic tool (nick-named the '4/10 strategy') for discovering, evaluating and exploiting entrepreneurial opportunities.

Gregory Palamas on the relationship between philosophy and theology

The relationship between philosophy and theology has rarely been a harmonious and fruitful one. The two disciplines are often segmented into mutually exclusive compartments. On the one hand, philosophers, particularly contemporary philosophers working within the Anglo-American analytic tradition, widely agree that the claims made by theologians – such as the claim that there is a God and that God is a trinity of persons – are meaningless, or false, or irrational, or unsupported by evidence, or in some other way epistemically below par. On the other hand, it is not unusual to find theologians following in the footsteps of writers such as Tertullian, Kierkegaard and Barth in arguing that, when it comes to theology, faith suffices and reason merely perverts.

The philosophy-theology dispute was no stranger to fourteenth-century Byzantium, particularly in the writings of the most prominent spiritual and intellectual figure of this period, viz., Gregory Palamas (c.1296-1359). In his debates with Barlaam of Calabria (c.1290-1348), Gregory Akindynos (c.1300-1348) and Nikephoros Gregoras (c.1290-c.1358), the issue of the appropriateness of employing philosophical terms and modes of reasoning in theology occupied a central place.[1] But before looking at how Palamas tackled this issue, it will be helpful, firstly, to briefly outline how the Christian world (especially in the East) prior to Palamas tended to see the relationship between secular learning (including philosophy) and theology; and secondly, to ascertain what exactly was Palamas’ conception of philosophy.
