Authors: Masiero A. , Fissore F. , Guarnieri A. , Pirotti F. , Vettore A.
Published: June 2016

Abstract. Nowadays photogrammetry and laser scanning methods are the most wide spread surveying techniques. Laser scanning methods usually allow to obtain more accurate results with respect to photogrammetry, but their use have some issues, e.g. related to the high cost of the instrumentation and the typical need of high qualified personnel to acquire experimental data on the field. Differently, photogrammetric reconstruction can be achieved by means of low cost devices and by persons without specific training. Furthermore, the recent diffusion of smart devices (e.g. smartphones) embedded with imaging and positioning sensors (i.e. standard camera, GNSS receiver, inertial measurement unit) is opening the possibility of integrating more information in the photogrammetric reconstruction procedure, in order to increase its computational efficiency, its robustness and accuracy. In accordance with the above observations, this paper examines and validates new possibilities for the integration of information provided by the inertial measurement unit (IMU) into the photogrammetric reconstruction procedure, and, to be more specific, into the procedure for solving the feature matching and the bundle adjustment problems.

Published: June 2016

Abstract. A spherical camera can observe the environment for almost 720 degrees’ field of view in one shoot, which is useful for augmented reality, environment documentation, or mobile mapping applications. This paper aims to develop a spherical photogrammetry imaging system for the purpose of 3D measurement through a backpacked mobile mapping system (MMS). The used equipment contains a Ladybug-5 spherical camera, a tactical grade positioning and orientation system (POS), i.e. SPAN-CPT, and an odometer, etc. This research aims to directly apply photogrammetric space intersection technique for 3D mapping from a spherical image stereo-pair. For this purpose, several systematic calibration procedures are required, including lens distortion calibration, relative orientation calibration, boresight calibration for direct georeferencing, and spherical image calibration. The lens distortion is serious on the ladybug-5 camera’s original 6 images. Meanwhile, for spherical image mosaicking from these original 6 images, we propose the use of their relative orientation and correct their lens distortion at the same time. However, the constructed spherical image still contains systematic error, which will reduce the 3D measurement accuracy. Later for direct georeferencing purpose, we need to establish a ground control field for boresight/lever-arm calibration. Then, we can apply the calibrated parameters to obtain the exterior orientation parameters (EOPs) of all spherical images. In the end, the 3D positioning accuracy after space intersection will be evaluated, including EOPs obtained by structure from motion method.
TUNNEL POINT CLOUD FILTERING METHOD BASED ON ELLIPTIC CYLINDRICAL MODEL

Published: June 2016

Abstract. The large number of bolts and screws that attached to the subway shield ring plates, along with the great amount of accessories of metal stents and electrical equipments mounted on the tunnel walls, make the laser point cloud data include lots of non-tunnel section points (hereinafter referred to as non-points), therefore affecting the accuracy for modeling and deformation monitoring. This paper proposed a filtering method for the point cloud based on the elliptic cylindrical model. The original laser point cloud data was firstly projected onto a horizontal plane, and a searching algorithm was given to extract the edging points of both sides, which were used further to fit the tunnel central axis. Along the axis the point cloud was segmented regionally, and then fitted as smooth elliptic cylindrical surface by means of iteration. This processing enabled the automatic filtering of those inner wall non-points. Experiments of two groups showed coincident results, that the elliptic cylindrical model based method could effectively filter out the non-points, and meet the accuracy requirements for subway deformation monitoring. The method provides a new mode for the periodic monitoring of tunnel sections all-around deformation in subways routine operation and maintenance.

Published: June 2016

Abstract. In the last years we have witnessed a rapid development of UAVs (Unmanned Aerial Vehicles), especially for image collection. One of the advantages is the possibility to perform high resolution and repeated flights in a cheap way to detect changes over time. Thus, dynamic scenes can be monitored acquiring image blocks in different epochs in a flexible way. Anyway, most of UAVs are not able to provide accurate direct geo-referencing information, so image blocks from different epochs still need to be co-registered to efficiently detect changes. This task is mostly completed using GCPs (Ground Control Points), although this approach is time consuming as manual intervention is needed. This paper aims at investigating new techniques to automate the co-registration of image blocks without the use of GCPs, just relying on an image based co-registration (IBCR) approach. The image alignment is initially performed on a reference (anchor) epoch and the registration of the following (slave) epochs is performed including some (anchor) images from the reference epoch with fixed external orientation parameters. This allows constraining the Bundle Block Adjustment of the slave epoch to be consistent with the reference one. The study involved the use of 10 multi-temporal image block over a large building construction site, and spanning a time frame of 2 years. Different tests have been performed for the reference image choice with a manual approach and then evaluating the reached accuracy. The performed tests on the chosen test site have shown that the accuracy of the proposed methodology provides results comparable to the common GCPs registration approach.
POSSIBILITIES FOR USING LIDAR AND PHOTOGRAMMETRIC DATA OBTAINED WITH AN UNMANNED AERIAL VEHICLE FOR LEVEE MONITORING

Published: June 2016

Abstract. This paper presents the possibilities for using an unmanned aerial system for evaluation of the condition of levees. The unmanned aerial system is equipped with two types of sensor. One is an ultra-light laser scanner, integrated with a GNSS receiver and an INS system; the other sensor is a digital camera that acquires data with stereoscopic coverage. Sensors have been mounted on the multirotor, unmanned platform the Hawk Moth, constructed by MSP company. LiDAR data and images of levees the length of several hundred metres were acquired during testing of the platform. Flights were performed in several variants. Control points measured with the use of the GNSS technique were considered as reference data. The obtained results are presented in this paper; the methodology of processing the acquired LiDAR data, which increase in accuracy when low accuracy of the navigation systems occurs as a result of systematic errors, is also discussed. The Iterative Closest Point (ICP) algorithm, as well as measurements of control points, were used to georeference the LiDAR data. Final accuracy in the order of centimetres was obtained for generation of the digital terrain model. The final products of the proposed UAV data processing are digital elevation models, an orthophotomap and colour point clouds. The authors conclude that such a platform offers wide possibilities for low-budget flights to deliver the data, which may compete with typical direct surveying measurements performed during monitoring of such objects. However, the biggest advantage is the density and continuity of data, which allows for detection of changes in objects being monitored.

Published: June 2016

Abstract. In recent years, many studies revealed the advantages of using airborne oblique images for obtaining improved 3D city models (e.g. including façades and building footprints). Expensive airborne cameras, installed on traditional aerial platforms, usually acquired the data. The purpose of this paper is to evaluate the possibility of acquire and use oblique images for the 3D reconstruction of a historical building, obtained by UAV (Unmanned Aerial Vehicle) and traditional COTS (Commercial Off-the-Shelf) digital cameras (more compact and lighter than generally used devices), for the realization of high-level-of-detail architectural survey. The critical issues of the acquisitions from a common UAV (flight planning strategies, ground control points, check points distribution and measurement, etc.) are described. Another important considered aspect was the evaluation of the possibility to use such systems as low cost methods for obtaining complete information from an aerial point of view in case of emergency problems or, as in the present paper, in the cultural heritage application field. The data processing was realized using SfM-based approach for point cloud generation: different dense image-matching algorithms implemented in some commercial and open source software were tested. The achieved results are analysed and the discrepancies from some reference LiDAR data are computed for a final evaluation. The system was tested on the S. Maria Chapel, a part of the Novalesa Abbey (Italy).
INVESTIGATIONS ON THE POSSIBILITIES OF MONITORING COASTAL CHANGES INCLUDING SHALLOW UNDER WATER AREAS WITH UAS PHOTO BATHMETRY
Authors: Grenzdörffer G. J. , Naumann M.
Published: June 2016

Abstract. UAS become a very valuable tool for coastal morphology. Not only for mapping but also for change detection and a better understanding of processes along and across the shore. This contribution investigates the possibilities of UAS to determine the water depth in clear shallow waters by means of the so called "photo bathymetry". From the results of several test flights it became clear that three factors influence the ability and the accuracy of bathymetric sea floor measurements. Firstly, weather conditions. Sunny weather is not always good. Due to the high image resolution the sunlight gets focussed even in very small waves causing moving patterns on shallow grounds with high reflection properties, such as sand. This effect invisible under overcast weather conditions. Waves, may also introduce problems and mismatches. Secondly the quality and the accuracy of the georeferencing with SFM algorithms. As multi image key point matching will not work over water, the proposed approach will only work for projects closely to the coastline with enough control on the land. Thirdly the software used and the intensity of post processing and filtering. Refraction correction and the final interpolation of the point cloud into a DTM are the last steps. If everything is done appropriately, accuracies in the bathymetry in the range of 10 – 50 cm, depending on the water depth are possible.

Published: June 2016

Abstract. Smart-camera can not only be operated under network environment anytime and any place but also cost less than the existing photogrammetric UAV since it provides high-resolution image, 3D location and attitude data on a real-time basis from a variety of built-in sensors. This study’s proposed UAV photogrammetric method, low-cost UAV and smart camera were used. The elements of interior orientation were acquired through camera calibration. The image triangulation was conducted in accordance with presence or absence of consideration of the interior orientation (IO) parameters determined by camera calibration, The Digital Elevation Model (DEM) was constructed using the image data photographed at the target area and the results of the ground control point survey. This study also analyzes the proposed method’s application possibility by comparing a Ortho-image the results of the ground control point survey. Considering these study findings, it is suggested that smartphone is very feasible as a payload for UAV system. It is also expected that smartphone may be loaded onto existing UAV playing direct or indirect roles significantly.
ROBUST MOSAICKING OF UAV IMAGES WITH NARROW OVERLAPS
Authors: Kim J. , Kim T. , Shin D. , Kim S. H.
Published: June 2016

Abstract. This paper considers fast and robust mosaicking of UAV images under a circumstance that each UAV images have very narrow overlaps in-between. Image transformation for image mosaicking consists of two estimations: relative transformations and global transformations. For estimating relative transformations between adjacent images, projective transformation is widely considered. For estimating global transformations, panoramic constraint is widely used. While perspective transformation is a general transformation model in 2D-2D transformation, this may not be optimal with weak stereo geometry such as images with narrow overlaps. While panoramic constraint works for reliable conversion of global transformation for panoramic image generation, this constraint is not applicable to UAV images in linear motions. For these reasons, a robust approach is investigated to generate a high quality mosaicked image from narrowly overlapped UAV images. For relative transformations, several transformation models were considered to ensure robust estimation of relative transformation relationship. Among them were perspective transformation, affine transformation, coplanar relative orientation, and relative orientation with reduced adjustment parameters. Performance evaluation for each transformation model was carried out. The experiment results showed that affine transformation and adjusted coplanar relative orientation were superior to others in terms of stability and accuracy. For global transformation, we set initial approximation by converting each relative transformation to a common transformation with respect to a reference image. In future work, we will investigate constrained relative orientation for enhancing geometric accuracy of image mosaicking and bundle adjustments of each relative transformation model for optimal global transformation.

Published: June 2016

Abstract. In this paper we present the further evaluation of DLR’s modular airborne camera system MACS-Micro for small unmanned aerial vehicle (UAV). The main focus is on standardized calibration procedures and on photogrammetric workflows. The current prototype consists of an industrial grade frame imaging camera with 12 megapixel resolutions and a compact GNSS/IMU solution which are operated by an embedded computing unit (CPU). The camera was calibrated once pre-flight and several times post-flight over a period of 5 month using a three dimensional test field. The verification of the radiometric quality of the acquired images has been done under controlled static conditions and kinematic conditions testing different demosaicing methods. The validation of MACS-Micro is done by comparing a traditional photogrammetric evaluation with the workflows of Agisoft Photoscan and Pix4D Mapper. The analyses are based on an aerial survey of an urban environment using precise ground control points and acquired GNSS observations. Aerial triangulations with different configuratrions of ground control points (GCP’s) had been calculated, comparing the results of using a camera self-calibration and introducing fixed interior orientation parameters for Agisoft and Pix4D. The results are promising concerning the metric characteristics of the used camera and achieved accuracies in this test case. Further aspects have to be evaluated by further expanded test scenarios.

Abstract. Updating the cadastre requires much work carried out by surveying companies in countries that have still not solved the problem of updating the cadastral data. In terms of the required precision, these works are among the most accurate. This raises the question: to what extent may modern digital photogrammetric methods be useful in this process? The capabilities of photogrammetry have increased significantly after the introduction of digital aerial cameras and digital technologies. For the registration of cadastral objects, i.e., land parcels’ boundaries and the outlines of buildings, very high-resolution aerial photographs can be used. The paper relates an attempt to use an alternative source of data for this task - the development of images acquired from UAS platforms. Multivariate mapping of cadastral parcels was implemented to determine the scope of the suitability of low altitude photos for the cadastre. In this study, images obtained from UAS with the GSD of 3 cm were collected for an area of a few square kilometres. Bundle adjustment of these data was processed with sub-pixel accuracy. This led to photogrammetric measurements being carried out and the provision of an orthophotomap (orthogonalized with a digital surface model from dense image matching of UAS images). Geometric data related to buildings were collected with two methods: stereoscopic and multi-photo measurements. Data related to parcels’ boundaries were measured with monoplotting on an orthophotomap from low-altitude images. As reference field surveying data were used. The paper shows the potential and limits of the use of UAS in a process of updating cadastral data. It also gives recommendations when performing photogrammetric missions and presents the possible accuracy of this type of work.
Augmenting ViSP’s 3D Model-Based Tracker with RGB-D SLAM for 3D Pose Estimation in Indoor Environments
Authors: Li-Chee-Ming J. , Armenakis C.
Published: June 2016

Abstract. This paper presents a novel application of the Visual Servoing Platform’s (ViSP) for pose estimation in indoor and GPS-denied outdoor environments. Our proposed solution integrates the trajectory solution from RGBD-SLAM into ViSP’s pose estimation process. Li-Chee-Ming and Armenakis (2015) explored the application of ViSP in mapping large outdoor environments, and tracking larger objects (i.e., building models). Their experiments revealed that tracking was often lost due to a lack of model features in the camera’s field of view, and also because of rapid camera motion. Further, the pose estimate was often biased due to incorrect feature matches. This work proposes a solution to improve ViSP’s pose estimation performance, aiming specifically to reduce the frequency of tracking losses and reduce the biases present in the pose estimate. This paper explores the integration of ViSP with RGB-D SLAM. We discuss the performance of the combined tracker in mapping indoor environments and tracking 3D wireframe indoor building models, and present preliminary results from our experiments.

Published: June 2016

Abstract. The rapid development of unmanned aerial vehicles is a challenge for applied research. Many technologies are developed and then researcher are looking up for their application in different sectors. Therefore, we decided to verify the use of the unmanned aerial vehicle for wood chips pile monitoring. We compared the use of GNSS device and unmanned aerial vehicle for volume estimation of four wood chips piles. We used DJI Phantom 3 Professional with the built-in camera and GNSS device (geoexplorer 6000). We used Agisoft photoscan for processing photos and ArcGIS for processing points. Volumes calculated from pictures were not statistically significantly different from amounts calculated from GNSS data and high correlation between them was found (p = 0.9993). We conclude that the use of unmanned aerial vehicle instead of the GNSS device does not lead to significantly different results. Tthe data collection consumed from almost 12 to 20 times less time with the use of UAV. Additionally, UAV provides documentation trough orthomosaic.
LIGHT-WEIGHT MULTISPECTRAL UAV SENSORS AND THEIR CAPABILITIES FOR PREDICTING GRAIN YIELD AND DETECTING PLANT DISEASES
Authors: Nebiker S. , Lack N. , Abächerli M. , Läderach S.
Published: June 2016

Abstract. In this paper we investigate the performance of new light-weight multispectral sensors for micro UAV and their application to selected tasks in agronomical research and agricultural practice. The investigations are based on a series of flight campaigns in 2014 and 2015 covering a number of agronomical test sites with experiments on rape, barley, onion, potato and other crops. In our sensor comparison we included a high-end multispectral multiSPEC 4C camera with bandpass colour filters and reference channel in zenith direction and a low-cost, consumer-grade Canon S110 NIR camera with Bayer pattern colour filters. Ground-based reference measurements were obtained using a terrestrial hyperspectral field spectrometer. The investigations show that measurements with the high-end system consistently match very well with ground-based field spectrometer measurements with a mean deviation of just 0.01-0.04 NDVI values. The low-cost system, while delivering better spatial resolutions, expressed significant biases. The sensors were subsequently used to address selected agronomical questions. These included crop yield estimation in rape and barley and plant disease detection in potato and onion cultivations. High levels of correlation between different vegetation indices and reference yield measurements were obtained for rape and barley. In case of barley, the NDRE index shows an average correlation of 87% with reference yield, when species are taken into account. With high geometric resolutions and respective GSDs of down to 2.5 cm the effects of a thrips infestation in onion could be analysed and potato blight was successfully detected at an early stage of infestation.
BUDGET UAV SYSTEMS FOR THE PROSPECTION OF SMALL- AND MEDIUM-SCALE ARCHAEOLOGICAL SITES
Authors: Ostrowski W. , Hanus K.
Published: June 2016

Abstract. One of the popular uses of UAVs in photogrammetry is providing an archaeological documentation. A wide offer of low-cost (consumer) grade UAVs, as well as the popularity of user-friendly photogrammetric software allowing obtaining satisfying results, contribute to facilitating the process of preparing documentation for small archaeological sites. However, using solutions of this kind is much more problematic for larger areas. The limited possibilities of autonomous flight makes it significantly harder to obtain data for areas too large to be covered during a single mission. Moreover, sometimes the platforms used are not equipped with telemetry systems, which makes navigating and guaranteeing a similar quality of data during separate flights difficult. The simplest solution is using a better UAV, however the cost of devices of such type often exceeds the financial capabilities of archaeological expeditions. The aim of this article is to present methodology allowing obtaining data for medium scale areas using only a basic UAV. The proposed methodology assumes using a simple multirotor, not equipped with any flight planning system or telemetry. Navigating of the platform is based solely on live-view images sent from the camera attached to the UAV. The presented survey was carried out using a simple GoPro camera which, from the perspective of photogrammetric use, was not the optimal configuration due to the fish eye geometry of the camera. Another limitation is the actual operational range of UAVs which in the case of cheaper systems, rarely exceeds 1 kilometre and is in fact often much smaller. Therefore the surveyed area must be divided into sub-blocks which correspond to the range of the drone. It is inconvenient since the blocks must overlap, so that they will later be merged during their processing. This increases the length of required flights as well as the computing power necessary to process a greater number of images. These issues make prospection highly inconvenient, but not impossible. Our paper presents our experiences through two case studies: surveys conducted in Nepal under the aegis of UNESCO, and works carried out as a part of a Polish archaeological expedition in Cyprus, which both prove that the proposed methodology allows obtaining satisfying results. The article is an important voice in the ongoing debate between commercial and academic archaeologists who discuss the balance between the required standards of conducting archaeological works and economic capabilities of archaeological missions.
VOLUME COMPUTATION OF A STOCKPILE – A STUDY CASE COMPARING GPS AND UAV MEASUREMENTS IN AN OPEN PIT QUARRY
Authors: Raeva P. L. , Filipova S. L. , Filipov D. G.
Published: June 2016

Abstract. The following paper aims to test and evaluate the accuracy of UAV data for volumetric measurements to the conventional GNSS techniques. For this purpose, an appropriate open pit quarry has been chosen. Two sets of measurements were performed. Firstly, a stockpile was measured by GNSS technologies and later other terrestrial GNSS measurements for modelling the berms of the quarry were taken. Secondly, the area of the whole quarry including the stockpile site was mapped by a UAV flight. Having considered how dynamic our world is, new techniques and methods should be presented in numerous fields. For instance, the management of an open pit quarry requires gaining, processing and storing a large amount of information which is constantly changing with time. Fast and precise acquisition of measurements regarding the process taking place in a quarry is the key to an effective and stable maintenance. In other words, this means getting an objective evaluations of the processes, using up-to-date technologies and reliable accuracy of the results. Often legislations concerning mine engineering state that the volumetric calculations are to present ±3% accuracy of the whole amount. On one hand, extremely precise measurements could be performed by GNSS technologies, however, it could be really time consuming. On the other hand, UAV photogrammetry presents a fast, accurate method for mapping large areas and calculating stockpiles volumes. The study case was performed as a part of a master thesis.
Improved retrieval of land ice topography from CryoSat-­2 data and its impact for volume change estimation of the Greenland Ice Sheet
Authors: Nilsson Johan , Gardner Alex , Sandberg Sørensen Louise , Forsberg Rene
Published: June 2016

Abstract. A new methodology for retrieval of glacier and ice sheet elevations and elevation changes from CryoSat-2 data is presented. Surface elevations and elevation changes determined using this approach show significant improvements over ESA's publically available Cryosat-2 elevation product (L2 Baseline-B). This when compared to near-coincident airborne laser altimetry from NASA's Operation IceBridge and seasonal height amplitudes from the Ice, Cloud, and Elevation Satellite (ICESat). Applying this methodology to CryoSat-2 data collected in Interferometric Synthetic Aperture mode over the high relief regions of the Greenland ice sheet we find an improvement in the root-mean-square-error (RMSE) of 27 % and 40 % compared to ESA's L2 product in the derived elevation and elevation changes, respectively. In the interior part of the ice sheet, where CryoSat-2 operates in Low Resolution Mode, we find an improvement in the RMSE of 68 % and 55 % in the derived elevation and elevation changes, respectively. There is also an 86 % improvement in the magnitude of the seasonal amplitudes when compared to amplitudes derived from ICESat data. These results indicate that the new methodology provides improved tracking of the snow/ice surface with lower sensitivity to changes in near-surface dielectric properties. To demonstrate the utility of the new processing methodology we produce elevations, elevation changes and total volume changes from Cryosat-2 data for Greenland Ice Sheet during the period Jan-2011 to Jan-2015. We find that the Greenland Ice Sheet decreased in volume at rate of 289 ± 16 km3 a−1, with high inter-annual variability and spatial heterogeneity in rates of loss. This rate is 65 km3 a−1 more negative than rates determined from ESA's L2 product, highlighting the importance of Cryosat-2 processing methodologies.
Comparison of hybrid schemes for the combination of Shallow Approximations in numerical simulations of the Antarctic Ice Sheet
Authors: Bernales Jorge , Rogozhina Irina , Greve Ralf , Thomas Maik
Published: June 2016

Abstract. The Shallow Ice Approximation (SIA) is commonly introduced in ice-sheet models to simplify the equations describing ice dynamics. However, the SIA is not applicable in fast flowing regions where basal sliding operates. To overcome this limitation, recent studies have introduced heuristic, hybrid combinations of the SIA and the Shelfy Stream Approximation. Here, we implement four different hybrid schemes into a model of the Antarctic Ice Sheet in order to compare their performance under a realistic scenario. For each scheme, the model is calibrated using an iterative technique to infer the spatial variability in basal sliding parameters. Model results are validated against topographic and velocity data. Our analysis shows that the calibration compensates for the differences between the schemes, producing similar ice sheet configurations through quantitatively different parameter distributions. Despite this, we observe a robust agreement in the reconstructed patterns of hard vs. soft basal conditions. We use averaged and swapped parameter distributions to demonstrate that the results of the model calibration cannot be straightforwardly transferred to models based on different approximations of ice dynamics. However, this requirement for internal consistency can be fulfilled through the implementation of easily adaptable calibration techniques, as shown in this study.
Teaching independent learning skills in the first year: A positive psychology strategy for promoting law student well-being
Authors: Field Rachael , Duffy James , Huggins Anna
Published: June 2016

Empirical evidence in Australia and overseas has established that in many university disciplines, students begin to experience elevated levels of psychological distress in their first year of study. There is now a considerable body of empirical data that establishes that this is a significant problem for law students. Psychological distress may hamper a law student’s capacity to learn successfully, and certainly hinders their ability to thrive in the tertiary environment. We know from Self-Determination Theory (SDT), a conceptual branch of positive psychology, that supporting students’ autonomy in turn supports their well-being. This article seeks to connect the literature on law student well-being and independent learning using Self-Determination Theory (SDT) as the theoretical bridge. We argue that deliberate instruction in the development of independent learning skills in the first year curriculum is autonomy supportive. It can therefore lay the foundation for academic and personal success at university, and may be a protective factor against decline in law student psychological well-being

Published: June 2016

Since “Courting the Blues” was published by Kelk, Luscombe, Medlow and Hickie in 2009, legal educators across Australia have been measuring psychological distress in law students, as well as implementing and evaluating strategies to support students’ well-being. This paper reports on initiatives implemented at the Newcastle Law School in 2012 designed to reduce performance anxiety around a compulsory first year mooting assessment, and the implementation of a self-management curriculum underpinned by the fruits of research in self-determination theory in 2013, involving a partnership between legal academics and professional colleagues from the University Counselling Service. In particular, the paper will analyse the use of the My Journey transition resource, input on growth mindset, reflective practice, resilience training, and practical mindfulness as strategies to support well-being of law students
Creating practice ready, well and professional law graduates
Authors: Ferguson Anneka
Published: June 2016

There is a growing movement to create successful, ethical, well-rounded and practice ready legal professionals both in terms of their content knowledge and their mental well-being. As a Legal Teaching “profession” it is incumbent on us to answer this call in a responsive, creative, integrated, well researched and evaluated manner. This paper provides a suggested and evaluated framework for how this call can be met without resorting to “add on” subjects (no matter how well-intentioned), that stand outside the “normal” law school curriculum. Instead of partitioning well-being and professionalism into separate silos, it is suggested that all efforts must be made to integrate the seeds, thoughts, and actions of ethics, well-being, and professionalism into as many aspects of each of our programs as possible.
Improving students’ interpersonal skills through experiential small group learning.
Authors: Skinner Kay Lesley , Hyde Sarah J , McPherson Kerstin B.A. , Simpson Maree D
Published: June 2016

Health professional students must be equipped with the skills necessary to interact with patients. Effective interpersonal skills are difficult to both learn and teach, requiring development, practise and evaluation in both educational and clinical settings. In professions such as physiotherapy, there have traditionally been two approaches to teaching these skills: clinical modelling, and stand-alone didactic teaching of the theory behind communication. These approaches provide limited opportunity for students to practise and receive feedback on their interpersonal and communication skills. This paper describes the implementation of an experiential small group learning approach in an undergraduate physiotherapy program and discusses outcomes and challenges from both student and staff perspectives. Implications for practice are that: experientially based small group learning with opportunities for practise, reflection, self-evaluation and feedback, can improve students’ interpersonal skills; consistent and scaffolded participation in experiential learning opportunities and assessment across the program is key to this approach; a small group experiential learning approach can contribute to increased student satisfaction with the support they receive; and interpersonal skills still remain a challenge for new graduates. Support and mentoring in this domain may enhance the transition to work.
Eating for Health and the Environment: Australian Regulatory Responses For Dietary Change
Authors: Johnson Hope
Published: June 2016

The Australian food system significantly contributes to a range of key environmental issues, including harmful greenhouse gas emissions, air pollution, soil desertification, biodiversity loss and water scarcity. At the same time, the Australian food system is a key cause of public health nutrition issues that stem from the co-existence of over- and under-consumption of dietary energy and nutrients. Within these challenges lie synergies and opportunities, because a diet that has a lower environmental impact generally aligns with good nutrition. Australian State and Federal initiatives to influence food consumption patterns focus on individual body weight and ‘soft law’ interventions. These regulatory approaches, by focusing on select symptoms of food system failures, are fragmented, reductionist and inefficient. In order to illustrate this point, this article will explore Australian regulatory responses to diet-related illnesses. The analysis will support the argument that only when regulatory responses to diets become embedded within reform of the current food system, will substantial improvements to human and planetary health be achieved.
Teitiota v The Chief Executive Of Ministry Of Business, Innovation And Employment- A Person Displaced
Authors: Baker-Jones Mark , Baker-Jones Melanie
Published: June 2016

Small Island States are the most exposed and vulnerable to the impacts of climate change, particularly sea level rise. Unfortunately, mitigation measures, building capacity for the vulnerable groups, or even the adoption of adaptation measures may not be a sufficient solution. Instead, resettlement outside their country of origin may in some instances, be the only alternative. With resettlement however comes other issues, not least are the grounds under which they might qualify for another countries protection. In this article, we examine the case of Ioane Teitiota, who in 2013 applied to Immigration New Zealand for refugee status under the Convention Relating to the Status of Refugees as a ‘climate change refugee’. His application was refused because he failed to meet the current criteria required to demonstrate refugee status. Teitiota’s case, reflects what appears to be the dominant situation of displaced peoples who apply for refugee status on the ground of the impacts of climate change. Aside from the Convention, it is questionable whether the rights of people affected by climate change are protected under international law. There are a number of solutions mooted for resolution of the issue of climate displacement however as yet, none have gained international agreement.
Industrial Relations in Queensland Under an LNP Government
Authors: Anderson Michael , Brauns Thomas
Published: June 2016

The Liberal National Party (‘LNP’) won 78 out of a possible 89 seats in Queensland’s 2012 state election. Facing a budget blowout, the new Government soon used its control of the state’s unicameral parliament to implement a contentious public sector reform agenda. The LNP’s amendments to Queensland’s employment laws struck at the very heart of many of the accepted ‘ground rules’ of industrial relations. Perhaps most signif-icantly, the Government used its parliamentary majority to remove job security commit-ments given to public servants, paving the way for the loss of thousands of jobs. This paper sets out the key industrial relations reforms adopted by the LNP. The authors dis-cuss the Government’s rationale for the changes, and the reaction from Queensland’s trade union movement. The article concludes with some general observations about the changes adopted during the LNP’s term of Government; a period which will undoubtedly be remembered as a controversial part of Queensland’s industrial relations history.
Legalised Physician-Assisted Death in Oregon
Authors: Ganzini Linda
Published: June 2016

In the United States, five states have legalised physician-assisted death (PAD), but most information and research comes from the state of Oregon, in which the practice has been legal since 1997. This law allows a physician to prescribe a lethal dosage of medicine to terminally ill, mentally competent residents, for the purposes of self-administration. Each year about 3 in 1000 deaths are from PAD and the patients most often have cancer or amyotrophic lateral sclerosis. Concerns that legalisation would undermine the development of palliative care and be disproportionately utilised by patients unable to access good end of life care have been unfounded. 
How the UK Overcame the Ethical, Legal and Professional Challenges in Donation After Circulatory Death
Authors: Gardiner Dale
Published: June 2016

Long transplant lists and a shortage of organ donors has led to an international resurgence in the donation of organs after circulatory death (‘DCD’). Despite being almost entirely absent for nearly 25 years, DCD now accounts for 40 per cent of deceased organ donation in the UK. This rise is in part due to attempts to resolve the ethical, legal and professional challenges inherent to this type of donation. Since 2008 in the UK, seven major ethical, legal and professional guidances have been published relating to deceased donation and DCD in particular. It is now this author’s opinion that the professional framework that underpins the DCD programme in the UK is the strongest in the world. This paper outlines the seven UK publications that justify this bold claim.
Texas Advance Directives Act: Nearly a Model Dispute Resolution Mechanism for Intractable Medical Futility Conflicts
Authors: Pope Thaddeus Mason
Published: June 2016

Increasingly, clinicians and commentators have been calling for the establishment of special adjudicatory dispute resolution mechanisms to resolve intractable medical futility disputes. As a leading model to follow, policymakers both around the United States and around the world have been looking to the conflict resolution provisions in the 1999 Texas Advance Directives Act (‘TADA’). In this article, I provide a complete and thorough review of the purpose, history, and operation of TADA. I conclude that TADA is a commendable attempt to balance the competing goals of efficiency and fairness in the resolution of these time-sensitive life-and-death conflicts. But TADA is too lopsided. It is far more efficient than it is fair. TADA should be amended to better comport with fundamental notions of procedural due process.
A LEXICULTURA NO PORTUGUÊS DE MOÇAMBIQUE
Authors: TIMBANE Alexandre
Published: June 2016

A presente pesquisa discute a interação entre o léxico e a cultura no seio de uma comunidade linguística. A pesquisa tem por objetivos identificar traços léxico-culturais nos principais jornais de circulação em Moçambique e explicar a ligação entre o léxico e a cultura tendo em conta os contextos socioculturais. Baseado num corpus recolhido nos jornais “Notícias” e “Verdade” se conclui que os neologismos estão intimamente ligados à cultura e refletem o que acontece num determinado período do tempo e num dado lugar. A pesquisa conclui que alguns neologismos resistem ao tempo, alguns desaparecem e outros se atualizam dando a entender que as línguas são dinâmicas e se movimentam com base em variáveis sociais. Conclui-se ainda que o léxico do Português de Moçambique distancia-se das outras variedades do português devido à estreita ligação com a cultura dos falantes das diversas línguas bantu moçambicanas que interagem entre si e quando entram em contato com o português, por ser esta, a língua oficial de Moçambique.

Authors: Roder CARMONA-RAMIRES Andréia C. , De Andrade AGUILERA Vanderci
Published: June 2016

Por meio da pesquisa do léxico de uma língua, podemos ampliar nosso conhecimento sobre a cultura, história e sobre a identidade do povo que a fala. Com o objetivo de desenvolver mais pesquisas na área do léxico em Língua Espanhola, buscamos analisar neste artigo, os sentidos relacionados à unidade léxica PAZ, bem como o que refletem seus significados com relação ao contexto histórico (político-militar) expressos no vocabulário de publicação noticiosa em Língua Espanhola, ou seja, o jornal La Vanguardia dos anos de 1940 e 1975 da ditadura do General Francisco Franco, na Espanha. Para a elaboração deste estudo, nos embasamos na Linguística de Corpus (BERBER-SARDINHA, 2004; FROMM, 2003; PIÑOL, 2012) e para efeito de descrição e análise, orientamo-nos em princípios da Lexicologia (FERNÁNDEZ-SEVILLA, 1982; BIDERMAN, 1998, 2001; OLANO, 2004) e da Semântica Lexical (LOPES; PIETROFORTE, 2004; HENRIQUES, 2010-2011; ESCANDELL VIDAL, 2012; WACHOWICZ, 2013).
FORMAS DE TRATAMENTO EM TRADUÇÕES DE “THE ADVENTURES OF TOM SAWYER”: RELAÇÕES SOCIAIS E AFETIVAS
Authors: Mantovani DAL CORNO Giselle Olivia , SOPPELSA Fernanda Bondam
Published: June 2016

Mark Twain, renomado autor realista, conhecido pelo seu estilo coloquial e pelo local colorism, representa com maestria a modalidade oral regional da língua inglesa na fala dos personagens do romance “The adventures of Tom Sawyer” (“As aventuras de Tom Sawyer”). As formas de tratamento empregadas pelos personagens principais ajudam a construir uma representação de como as relações sociais são marcadas na obra. A partir da análise de alguns diálogos do texto original em inglês e de suas respectivas traduções, observa-se não somente as marcas de oralidade, mas também como as escolhas lexicais para formas de tratamento podem revelar diferentes graus de afetividade e hierarquia social. Verificam-se alguns casos de perdas nas traduções brasileiras em relação ao uso das formas de tratamento, como também, em uma das traduções, um processo de domesticação, nos moldes de Venutti (1998).
O QUE TORNA UMA ANÁLISE DISCURSIVA? PERCURSO HISTÓRICO DE COMPREENSÃO
Authors: Caetano de PAULA Carine Fonseca , FERNANDES JÚNIOR Antônio
Published: June 2016

Em meio a outros tipos de análise das linguagens – como, por exemplo, as análises de conteúdo, análise semiótica, literária ou das imagens – a necessidade de compreender a Análise do Discurso (doravante AD) como um campo teórico-metodológico e buscar pela especificidade daquilo que a torna propriamente discursiva, diferenciando-a de outros tipos de análise, é o objetivo de desenvolvimento deste artigo. Para isso, optou-se por traçar um breve percurso de compreensão acerca do modo de operar da análise discursiva, como ela se constitui epistemologicamente em um campo científico, na perspectiva pecheutiana, para, ao final, apresentá-la como uma análise “crítica” da linguagem, dando ênfase à relação entre Discurso e História.
A LINGUAGEM E A CONTINGÊNCIA DO HUMANO
Authors: AYUB João Paulo
Published: June 2016

O artigo pretende discutir o caráter não fixado da natureza humana a partir de considerações sobre o domínio contingente da linguagem. O tema da não fixação do humano numa natureza pré-determinada repercute de modo central nas preocupações teóricas do campo de estudos da antropologia filosófica. O texto deve mostrar, contudo, que a reflexão acerca da linguagem abre um leque considerável de opções para o aprofundamento desta investigação. Para tanto, serão destacadas algumas contribuições dos campos de estudo da literatura, da educação e da antropologia.
O SUJEITO FEMINISTA PELA NARRADORA DE LYA LUFT
Authors: Rodrigues BRANDOLT Marlene
Published: June 2016

Tomo a obra de Lya Luft “O rio do meio” (1996), para discutir uma narrativa reveladora das transformações do sujeito feminista e do ato de criação. Procuro traçar uma perspectiva da construção do eu no feminismo, que pode ser identificado pelo leitor por meio da voz da narradora e sua relação com os possíveis eus. Ao analisar as diversas nuances assumidas pelo eu da narradora, abordo a forma como ele é contado, numa relação dialética, baseada em Hegel e na recepção de Wolfgang Iser e Paul Ricoeur. A abordagem do problema, feita por meio de uma narrativa caracterizada pela escolha de uma visão de mulher, vale-se de críticas ligadas aos estudos feministas de Claudia de Lima Costa, Rita Terezinha Schmidt, Vera Queiroz e Maria Célia Detoni, entre outras.
