A facility for the integration of live and virtual environments in realtime

This paper describes a research facility which has been established to explore the integration of live and virtual environments in real-time. The facility combines digital ontput from both live and electronic sources such as video, animatinos and 3D virtual environments and enables the monitoring and control of the interaction between live actors and the digital enviromnents. This provides a research environment in which the interaction between participants in the design and construction process and 3D virtual buildings can be investigated. This will lead to the enhancement of decision making and planning in the design and construction process.

Late Paleozoic depositional history of the Tarim basin, northwest China: an integration of biostratigraphic and lithostratigraphic constraints

This study provides the first detailed lithostratigraphic and biostratigraphic constraints for improving stratigraphic resolution for hydrocarbon prospecting and exploration in the Tarim basin. A total of 49 stratigraphic units (38 formations and 11 members), ranging in age from the latest Devonian to Permian, are reviewed or redefined in terms of nomenclatures, lithology, age constraints, and lateral distributions based on the detailed field works or newly published data. Of these, the Piqiang Formation (new formation) is proposed to include the reefal carbonates of Asselian-Sakmarian age from the northern Tarim. The subsurface upper Paleozoic stratigraphic framework of the desert areas of the basin is also established for the first time. The high-resolution, basinwide stratigraphic correlations reveal that the sedimentation of the basin in the late Paleozoic was extremely uneven. Of these, the Famennian to Changhsingian successions are completely recorded in the south-western margin areas of the basin. Here, five eustatic sedimentary cycles are well recognizable, suggesting the sedimentation was more eustatically controlled and little affected by local tectonism. The late Paleozoic successions of both Kalpin and Taklimakan regions are commonly interrupted by major hiatuses at various horizons, suggesting that the sedimentation was apparently modified by local tectonism. Of these, the northward movement of the Tarim block and its subsequent collision with the Yili microcontinent (part of the Kazakhstan plate) may be principally accountable for the discrepancy in the sedimentation of the various regions in the basin in the late Paleozoic.

Effective integration of teaching and research in a first year food and nutrition course

Previous research has indicated that undergraduate student learning can be enhanced through active involvement in research. Furthermore, creating an academic environment where teaching and research are intimately linked can facilitate the induction of students into a community of learners where new knowledge is created, explored and critiqued. Scaffolding and supporting student learning via engagement in authentic research experiences can work to ensure graduating students have the capacity to generate and investigate important questions that contributes to the development of new knowledge. This paper presents a case study that outlines curriculum design and pedagogical strategies aimed at integrating teaching and research within the first year of an undergraduate course. First year Food and Nutrition students were asked to partake in a research project where they were asked to complete a series of diet and food related questionnaires, analyse, interpret and critique the resulting data. Students were supported through this learning activity via small group tutorial support and question and answer sessions within the learning management system. Anonymous evaluation of the teaching and learning experience was conducted at the end of the teaching period and the results indicate that the students welcomed the opportunity to engage in an authentic, research based learning activity. Students’ found the assessment tasks were clearly explained to them (88% agreeing), and felt well supported in approaching this research based assessment task. Furthermore, the qualitative comments indicated that the students’ found the learning environment to be meaningful and relevant. This case study indicates that it is possible to effectively incorporate authentic research experiences within the curriculum of a first year course. The experiential, inquiry based learning approach used supported the students’ participation in a systematic, rigorous data collection process required in a structured research environment and blended these requirements with authentic learning of discipline specific skills and knowledge.

Assessing the impact of drought and forestry on streamflows in south-eastern Australia using a physically based hydrological model

An increase in plantation forestry has been linked to a reduction in streamflows in some catchments. Quantifying the relative contribution of this land-use change on streamflows can be complex when those changes occur during weather extremes such as drought. In this study, the Soil and Water Assessment Tool (SWAT) model was applied to two sub-catchments in south-eastern Australia which have seen the introduction and establishment of plantation land use in the past 15 years, coinciding with severe drought (1997–2009). The models were both manually and auto-calibrated and produced very good fits to observed streamflow data during both calibration (1980–1991) and validation (1992–2009) periods. Sensitivity analyses indicated that the models were most sensitive to soil and groundwater parameterisation. Analysis of drought conditions on streamflows showed significant declines from long-term average streamflows, while assessment of baseflow contributions by the models indicated a mix of over- and underestimation depending on catchment and season. The modelled introduction of plantation forestry did not significantly change streamflows for a scenario which did not include the land-use change, suggesting that the modelled land-use change in the catchments was not sufficiently extensive to have an impact on streamflows despite simulating actual rates of change. The SWAT models developed by this study will be invaluable as a basis for future use in regional climate-change studies and for the assessment of land management and land-use change impact on streamflows.

Impacts of integration of wind and solar PV in a typical power network

Integration of solar PV and wind in to the distribution network is one of the most promising challenges of the modern power system networks to meet the growing demand of energy. Analysis of the effects of solar and wind intermittencies in the network are vital to maintain the power quality. Keeping this in view, this research paper focuses on impact analysis study of a typical power network with hybrid generation: solar PV and wind integration to quantify the level of impacts like power variation and voltage variation in the network through load flow analysis. Initially, a typical network model is developed using PSS-SINCAL and load profile analysis has been carried out based on the typical daily load profile and wind/solar profile to verify the power and voltage variations extensively in the network considering different scenarios. Results of this research analysis can be used as guidelines for utility grid to provide regulated and improved quality of energy supply by implementing appropriate planning of generation reserve and other control measures in the network

Case study of the integration of ICT's into the school curriculum

This study, conducted in a laptop environment, found many factors mediate teachers' integration of information and communication technologies (ICTs) into the curriculum. Successful integration of ICTs was not so much related to pedagogical style and teachers' self-sufficiency with computers, as to the principle of 'teachers first' and professional development which utilizes a 'situative-learning' model.

Exploring the integration of social media within integrated marketing communication frameworks: perspectives of services marketers

Purpose – At present no frameworks exist for services marketers to incorporate social media (SM) within marketing communications planning. The majority of integrated marketing communications (IMC) frameworks were developed prior to the development of the widespread use of digital and SM for information seeking, sales and service. The purpose of this paper is to investigate this issue for services marketers specifically as they differ from FMCG, industrial and durable marketers in terms of marketing messages, branding, media and channels. Furthermore, as they are less reliant on outsourced sale channels they have more potential than other industries to integrate social and digital media to build awareness, brands and sales.

Design/methodology/approach – Depth interviews were conducted with eight senior services marketing executives to identify the impact of SM on marketing communications planning, implementation and measurement.

Findings – The findings revealed that the unique characteristics of SM (such as interactivity and individualisation, integration of communication and distribution channels, immediacy and information collection) impact traditional marketing communications frameworks. These impacts manifested in 12 modifications specific to services and SM to traditional generic IMC frameworks encompassed by the themes of reach, service channel, word-of-mouth advocacy, consumer generated messages, listening and behavioural measurement.

Practical implications – The rapidly evolving nature of SM means senior services marketers need to educate organisational stakeholders regarding implementation issues, which may be a barrier to effective integration of SM within marketing communications.

Originality/value – With digital marketing communications budgets reaching 30 per cent within some organisations, it is timely to put forward a marketing communication decision-making framework that first incorporates SM and second is suitable for services marketers.

Orientation integration in detection and discrimination of contrast-modulated patterns

Orientation detection and discrimination thresholds were measured for Gabor ‘envelopes’ formed from contrast-modulation of luminance ‘carriers’. Consistent with previous research differences between carrier and envelope orientation had no effect on sensitivity to envelopes. Using plaid carriers in which the proportion of contrast modulation ‘carried’ by each plaid component was systematically manipulated, it was shown that this tolerance to carrier-envelope orientation difference reflects linear summation across orientation indicative of a single second-stage channel coding for contrast-defined structure. That contrast envelopes did not exhibit linear summation across spatial-frequency, nor across combinations of orientation and spatial-frequency differences, suggests that these second-order channels operate only within certain spatial scales. Using arrays of Gabor micropatterns as carriers in which the orientation distribution of the carriers was manipulated independently of the difference between envelope orientation and mean carrier orientation, it was further demonstrated that the locus of orientation integration must occur prior to envelope detection. In the context of two-stage models that incorporate a non-linearity between the stages, the pattern of results obtained is consistent with the operation of an orientation pooling process between first-stage and second-stage channels, analogous to having all filters of the first-stage feed into all filters of the second-stage within the same spatial-frequency band.

Multi-temporal land use mapping using remotely sensed techniques and the integration of a pollutant load model in a GIS

Estimation of nutrient load production based on multi-temporal remotely sensed land-use data for the Glenelg-Hopkins region in southwest Victoria, Australia, is discussed. Changes in land use were mapped using archived Landsat data and computerized classification techniques. Land-use
change is unparalleled in recent history, with 13% of the region transformed in the last decade. Total nitrogen and phosphorus loading were estimated using an export coefficient model. The analysis demonstrated a disturbing increase in nitrogen and phosphorus loadings from 1995 to 2002. Whilst such increases were suspected from past anecdotal and ad-hoc evidence, our modelling quantitatively estimated such increases and thus demonstrated the enormous potential of using remote sensing and GIS for monitoring land-use change and hence improve land-use management.

System of systems approach to threat detection and integration of heterogeneous independently operable systems

This paper presents a system of systems approach to threat detection through integration of heterogeneous independently operable systems. The approach is presented on a realistic situation where a human-controlled base robot, swarm robot(s), and sensors work together to obtain a decision about a possible threat in the environment. The base robot is remotely operated by a human using a haptic control system. The swarm robot(s) are autonomous and can accept directives from the base robot. Finally, sensors directly communicate with (report to) the base robot. In this scenario, heterogeneous systems and human interact in a system of systems architecture. With the inclusion of human expert and sensor verification of swarm robots, the system can successfully perform the threat detection and reduce the false alarms. Finally, a system of systems simulation framework including a base robot, a swarm robot, and two sensors is presented in addition to an experimental evaluation of the proposed SoS architecture

Acting at the Nexus : integration of research, policy and practice

This report is the result of an exciting journey of discovery. As with all journeys, we have been to many exotic places, have met extraordinary people, and at times have been challenged to keep going ahead rather than retreating. Good journeys are also enjoyed best in good company. We would like to thank VicHealth for giving us the opportunity to embark on our voyage, but also specifically to some great VicHealth staff: John Biviano, Siân Lloyd, Barb Mouy and Ali Barr have all been travelers along the way, providing us with encouragement, directions and nourishment. We know that our Project Advisory Committee and the then Chief Executive of VicHealth, dr. Rob Moody, have followed our progress on the journey with great interest. A special word of thanks to professor David Hill, chair of our advisory committee and member of the VicHealth Board of Governance, to sit down with us and critically review our navigation procedures. But we could not have reached our destination without the great assistance of the people and agencies that gave us their time, energy, and sometimes precious resources, to engage in data collection for our case studies. Again, a particular word of appreciation, to professor Brian Head, and to Ruth Belben for her incredibly efficient assistance, in organising the ARACY workshop on 24 November, 2006 in which we were given an opportunity to triangulate our position with colleagues from research, policy and practice.

Integration of information literacy training into engineering and technology education

Information literacy has become an important skill for undergraduate students due to societal changes that have seen information become a valuable commodity, the need for graduates to become lifelong learners, and the recognition that information literacy is an underpinning generic skill for effective learning in higher education. This paper describes a sequence of purposefully designed activities to help students learn and practice information literacy skills that were integrated into a first-year engineering and technology study unit as a core element of the unit syllabus. A formal evaluation of these activities was planned and undertaken in semester 1 2003.
