Iraq's December 2005 election : reporting democratisation in the Australian and Middle Eastern print media

Throughout the coverage of Iraq since the Iran-Iraq War of the 1980s and especially since September 11, the Western mainstream Media have eschewed key historical and contextual data about Iraq, thereby serving to reduce and homogenize the complexity of the issues surrounding the region and the conflicts therein. In so doing, the media has tended towards Orientalism (Said, 1978) by trivialising Iraq and its people and thereby reinforcing the hegemony of the West over the ‘backward, barbaric’ East. Building on earlier research (Isakhan, 2005a), this paper further examines the reductive and homogenising reporting of Iraq in the Western media by using both quantitative and qualitative assessment methods to compare and contrast the discursive practices used to construct the Iraqi election of December 15, 2005 in Australia’s leading daily newspapers with newspapers from the Middle East. In essence, it finds that while the Australian media propagates Orientalism through its one-eyed coverage, the Middle Eastern papers are more contemplative, focusing on the impact that this election could have throughout the region.

Single-point isotope measurements in blood cells and plasma to estimate the time since diet switches

1. Understanding ecological phenomena often requires an accurate assessment of the timing of events. To estimate the time since a diet shift in animals without knowledge on the isotope ratios of either the old or the new diet, isotope ratio measurements in two different tissues (e.g. blood plasma and blood cells) at a single point in time can be used. For this ‘isotopic-clock’ principle, we present here a mathematical model that yields an analytical and easily calculated outcome.

2. Compared with a previously published model, our model assumes the isotopic difference between the old and new diets to be constant if multiple measurements are taken on the same subject at different points in time. Furthermore, to estimate the time since diet switch, no knowledge of the isotopic signature of tissues under the old diet, but only under the new diet is required.

3. The two models are compared using three calibration data sets including a novel one based on a diet shift experiment in a shorebird (red knot Calidris canutus); sensitivity analyses were conducted. The two models behaved differently and each may prove rather unsatisfactory depending on the system under investigation. A single-tissue model, requiring knowledge of both the old and new diets, generally behaved quite reliably.

4. As blood (cells) and plasma are particularly useful tissues for isotopic-clock research, we trawled the literature on turnover rates in whole blood, cells and plasma. Unfortunately, turnover rate predictions using allometric relations are too unreliable to be used directly in isotopic-clock calculations.

5. We advocate that before applying the isotopic-clock methodology, the propagation of error in the ‘time-since-diet-shift’ estimation is carefully assessed for the system under scrutiny using a sensitivity analysis as proposed here.

The effects of topological inaccuracy in evolutionary trees on the phylogenetic comparative method of independent contrasts

Computer simulations were used to test the effect of increasing phylogenetic topological inaccuracy on the results obtained from correlation tests of independent contrasts. Predictably, increasing the number of disruptions in the tree increases the likelihood of significant error in the r values produced and in the statistical conclusions drawn from the analysis. However, the position of the disruption in the tree is important: Disruptions closer to the tips of the tree have a greater effect than do disruptions that are close to the root of the tree. Independent contrasts derived from inaccurate topologies are more likely to lead to erroneous conclusions when there is a true significant relationship between the variables being tested (i.e., they tend to be conservative). The results also suggest that random phylogenies perform no better than nonphylogenetic analyses and, under certain conditions, may perform even worse than analyses using raw species data. Therefore, the use of random phylogenies is not beneficial in the absence of knowledge of the true phylogeny.

Recruitment into diabetes prevention programs : what is the impact of errors in self-reported measures of obesity?

Background
Error in self-reported measures of obesity has been frequently described, but the effect of self-reported error on recruitment into diabetes prevention programs is not well established. The aim of this study was to examine the effect of using self-reported obesity data from the Finnish diabetes risk score (FINDRISC) on recruitment into the Greater Green Triangle Diabetes Prevention Project (GGT DPP).

Methods
The GGT DPP was a structured group-based lifestyle modification program delivered in primary health care settings in South-Eastern Australia. Between 2004–05, 850 FINDRISC forms were collected during recruitment for the GGT DPP. Eligible individuals, at moderate to high risk of developing diabetes, were invited to undertake baseline tests, including anthropometric measurements performed by specially trained nurses. In addition to errors in calculating total risk scores, accuracy of self-reported data (height, weight, waist circumference (WC) and Body Mass Index (BMI)) from FINDRISCs was compared with baseline data, with impact on participation eligibility presented.

Results
Overall, calculation errors impacted on eligibility in 18 cases (2.1%). Of n&thinsp;=&thinsp;279 GGT DPP participants with measured data, errors (total score calculation, BMI or WC) in self-report were found in n&thinsp;=&thinsp;90 (32.3%). These errors were equally likely to result in under- or over-reported risk. Under-reporting was more common in those reporting lower risk scores (Spearman-rho&thinsp;=&thinsp;&minus;0.226, p-value&thinsp;<&thinsp;0.001). However, underestimation resulted in only 6% of individuals at high risk of diabetes being incorrectly categorised as moderate or low risk of diabetes.

Conclusions
Overall FINDRISC was found to be an effective tool to screen and recruit participants at moderate to high risk of diabetes, accurately categorising levels of overweight and obesity using self-report data. The results could be generalisable to other diabetes prevention programs using screening tools which include self-reported levels of obesity.

The relationship between labour market conditions and welfare receipt in Australia: A stock-flow analysis

Understanding the determinants of changes in welfare caseloads is an important, but little studied, topic in Australia. This paper evaluates the role of labour market conditions in explaining the changes in the Australian welfare caseload since the late 1990s. The paper employs a stock-flow approach to better control for persistence in welfare receipt and includes different specifications to deal with measurement error in labour market data. The results suggest that the labour market is an important determinant of movements on and off welfare, accounting for the majority of the caseload decline during 1997-2005. The results also highlight the importance of robustness checks when data are measured with error.

Informal settlements and placemaking : The case of Caracoli barrio in Bogotá

Placemaking in the developed world can be understood as a concept where through a social and political process, value and meaning in a particular setting is created. This focus of placemaking revolves around a setting in the urban environment, its role as a unique setting and, importantly, the people that make up this place: all of which is focused on a highly structured and formal participatory planning process.The role of placemaking in Latin America’s informal settlements, however, is largelyuntested. With more than 75% of Latin America’s population living in cities since 2001and over 30% (128 million people) of the urban population estimated to reside in what the United Nations define as slums; these informal settlements can offer alternative ways of thinking about urban space and the transformation of spaces people live in. In essence, informal settlements are, to a large extent, what people make of them through their own initiative and imagination. What they achieve is remarkable considering their limited resources and sometimes nonexistent participation in formal planning.Through empirical data collected in 2013 and 2014, this paper discusses how in theabsence of a formal participatory planning process (as the west or developed worldmay perceive it) and lack of resources the barrio of Caracoli, in Bogotá has been ableto create value and meaning in their place. This has been possible, despite social and economic difficulties –which are not to be forgotten-, through inventiveness and the richness of community members’ lives. In this sense, it can be argued that informal settlements can offer a different path to understanding the concept of placemaking currently dominating the developed world.

Quantification of spatial and thematic uncertainty in the application of underwater video for benthic habitat mapping

This study presents an analysis of the application of underwater video data collected for training and validating benthic habitat distribution models. Specifically, we quantify the two major sources of error pertaining to collection of this type of reference data. A theoretical spatial error budget is developed for a positioning system used to co-register video frames to their corresponding locations at the seafloor. Second, we compare interpretation variability among trained operators assessing the same video frames between times over three hierarchical levels of a benthic classification scheme. Propagated error in the positioning system described was found to be highly correlated with depth of operation and varies from 1.5m near the surface to 5.7m in 100m of water. In order of decreasing classification hierarchy, mean overall observer agreement was found to be 98% (range 6%), 82% (range 12%) and 75% (range 17%) for the 2, 4, and 6 class levels of the scheme, respectively. Patterns in between-observer variation are related to the level of detail imposed by each hierarchical level of the classification scheme, the feature of interest, and to the amount of observer experience. © 2014 Copyright © Taylor & Francis Group, LLC.

An alternative (partial) justification for the holding in Kirk

In Kirk v Industrial Court (NSW), the High Court determined that, based on“accepted doctrine at the time of Federation”, s 73 of the Constitutionentrenched the jurisdiction of the State Supreme Courts to review thedecisions of State decision-makers on the grounds of jurisdictional error. In anearlier article, the author argued that this reasoning was seriously flawed. Thisarticle propounds an alternative, partial justification for the holding in Kirk,based on features inherent in the text and structure of Ch III of the Constitutionat Federation and the preservation of those features in the face of thepost-Federation dismantling of the imperial legal system. It argues that animplication can be inserted into s 73 which entrenches the jurisdiction of theState Supreme Courts to review the decisions of “Lower State Courts”, but not“State Administrators”.

Informational spillovers in the pre-1914 London sovereign debt market

We document a novel type of international financial contagion whose driving force is shared financial intermediation. In the London peripheral sovereign debt market during pre-1914 period financial intermediation played a major informational role to investors, most likely because of the absence of international monitoring agencies and the substantial agency costs. Using two events of financial distress – the Brazilian Funding Loan of 1898 and the Greek Funding Loan of 1893 – as quasi-natural experiments, we document that, following the crises, the bond prices of countries with no meaningful economic links to the distressed countries, but shared the same financial intermediary, suffered a reduction relative to the rest of the market. This result is true for the mean, median and the whole distribution of bond prices, and robust to an extensive sensitivity analysis. We interpret it as evidence that the identity of the financial intermediary was informative, i.e, investors extracted information about the soundness of a debtor based on the existence of financial relationships. This spillover, informational in essence, arises as the flip-side of the relational lending coin: contagion arises for the same reason why relational finance, in this case, underwriting, helps alleviate informational and incentive problems.

Assesment of port governance in Brazil: a managerial perspective on the port of Santos

The role of maritime transportation within international trade was drastically revamped during the inception of the globalization process, which enhanced the contribution of ports in world economy as main logistics gateways for global production and trade. As a result, the relationship between ports and governments has changed. Devolution ideologies that had been applied in other industries decades ago were now being considered by governments for the port industry. Many central governments sought to extract themselves from commercial activities of ports and devolving this responsibility to local governments, communities or private entities. The institution of devolution programs also changed the governance structures of ports further influencing port performance. Consequently, the recent worldwide trend towards devolution in the port industry has spawned considerable variety of governance models that are now set in place around the world. While some countries opt for more decentralized structures others prefer to retain a centralization of powers. In this way some governments consider local features and national integration more than others, which ultimately influence the success of a port reform implementation. Nevertheless, the prime intent of governments is now to maximize the efficiency and performance of their domestic ports. This issue intends to examine the changed port governance environment in Brazil by determining how and why imposed port reforms of the Brazilian federal government have been affecting the overall performance of the national port system, over the last decades, using the Port of Santos as a sample upon an exploratory study. For that, the study will use a contingency theory-based framework – the Matching Framework - that views port performance as a function of the fit among the dimensions of external operating environment, strategy and structure of a port organization. In essence, the greater the fit among these dimensions the better the expected performance of a port will be, and vice-versa. Port managers, government officials and academics alike shall be interested in this document.

Application of ionospheric corrections in the equatorial region for L1 GPS users

In the absence of the selective availability, which was turned off on May 1, 2000, the ionosphere can be the largest source of error in GPS positioning and navigation. Its effects on GPS observable cause a code delays and phase advances. The magnitude of this error is affected by the local time of the day, season, solar cycle, geographical location of the receiver and Earth's magnetic field. As it is well known, the ionosphere is the main drawback for high accuracy positioning, when using single frequency receivers, either for point positioning or relative positioning of medium and long baselines. The ionosphere effects were investigated in the determination of point positioning and relative positioning using single frequency data. A model represented by a Fourier series type was implemented and the parameters were estimated from data collected at the active stations of RBMC (Brazilian Network for Continuous Monitoring of GPS satellites). The data input were the pseudorange observables filtered by the carrier phase. Quality control was implemented in order to analyse the adjustment and to validate the significance of the estimated parameters. Experiments were carried out in the equatorial region, using data collected from dual frequency receivers. In order to validate the model, the estimated values were compared with ground truth. For point and relative positioning of baselines of approximately 100 km, the values of the discrepancies indicated an error reduction better than 80% and 50% respectively, compared to the processing without the ionospheric model. These results give an indication that more research has to be done in order to provide support to the L1 GPS users in the Equatorial region.

Autopsy: quality assurance in the ICU

Objective: To examine the correlation between the clinical diagnosis and autopsy findings in adult patients who died in an intensive care unit (ICU). To determine the rate of agreement of the basic and terminal causes of death and the types of errors in order to improve quality control of future care,Design, Retrospective study.Setting: Adult ICU in a university hospital.Patients: 30 adult patients who died in the ICU. with the exclusion of medicolegal cases.Methods and main results: Anatomo-clinical meetings were held to analyze the pre- and postmortem correlations in 30 consecutive autopsies at the ICU of the University Hospital, School of Medicine of Botucatu/ UNESP, from January 1994 to January 1997. The rate of correct clinical diagnoses of the basic cause was 66.7 %; in 23.3 % of cases, if the correct diagnosis was made, management would have been different, as would have been the evolution of the patient's course (Class I error): in 10 % of the cases the error would not have led to a change in management (Class II error). The rate of correct clinical diagnoses of terminal cause was 80 %.Conclusions: the rate of recognition of the basic cause was 66.7 %, which is consistent with the literature, but the Class I error rate was higher than that reported in the literature.

The center of the incisive papilla for the selection of complete denture maxillary anterior teeth in 4 racial groups

Objectives: To evaluate the use of the center of the incisive papilla as a guide for the selection of the proper width of maxillary dentures in 4 racial groups. Method and Materials: One hundred sixty stone casts were obtained from impressions of the maxillary arch of white, black, mixed, and Asian subjects. The occlusal surfaces of the casts were photocopied and the images placed on a digitizer. The most anterior and posterior points of the papilla and cusp tips of the canines were digitized. Dentofacial Planner Plus software was used to calculate the distance from a line passing through the cusp tips of the canines to the center of the papilla, defined as the midpoint of the anterior and posterior points of the papilla. The selection error (in millimeters) due to the clinical application of the method of the incisive papilla was calculated and analyzed. Results: In all studied racial groups, there was no coincidence between the center of the incisive papilla and the canine line. The utilization of the center of the papilla would lead to the selection of wider artificial teeth. In 24.9% of the white, 19.3% of the mixed, 32.9% of the black, and 15.5% of the Asian populations, errors greater than 4 mm would be present with the utilization of the papilla. Conclusion: The method of the center of the incisive papilla is not accurate, but may aid in initial artificial teeth selection for the racial groups studied. (Quintessence Int 2008;39:841-845)
