From Permanent Settlement to Transnationalism – Contemporary Population Movement between Italy and Australia: Trends and Implications
Authors: Hugo Graeme 
Published: July 2013

AbstractAustralia has one of the largest communities of overseas Italians which has evolved from a number of waves of migration. The contemporary migration relationship between the two countries is complex involving movement in both directions, much of it temporary. This article demonstrates that although there has been little permanent migration from Italy to Australia for several decades there has been a substantial increase in non‐permanent movements in both directions. The article examines the characteristics of different types of movers and then addresses the implications of the mobility.

Published: July 2013

AbstractPressure ulcers (PUs) are a common problem in critically ill patients admitted to the intensive care units (ICUs) and they account for more than 70% of patients with low serum albumin at admission. The aim of this study was to test the efficacy of intravenous administration of albumin in patients with low serum albumin < 3·3 g/dl. In a 1‐year period, a total of 73 patients were admitted to the ICU (males 45, 61·64% and females 28, 38·36%); of these, 21 patients were admitted with hypoalbuminaemia (serum albumin < 3·3 g/dl) and randomised into two groups: 11 patients were treated with 25 g intravenous albumin for the first 3 days within the first week of ICU stay (group A) and 10 patients did not receive albumin (group B). Three patients (27·27%) showed the onset of PUs in group A, whereas seven patients (70%) showed the onset of PUs within the first 7 days of stay in group B. Moreover, ulcers of group B were more severe than those of group A. This study shows that intravenous administration of albumin reduces the onset of PUs in patients admitted to the ICU and in some cases it also reduces the risk of progression to advanced stages of PUs.

Métarégulation des relations professionnelles en Europe: mutations de pouvoirs, dynamique institutionnelle et émergence d'une concurrence entre les réglementations des Etats membres de l'UE
Authors: PAPADOPOULOS Theodoros , ROUMPAKIS Antonios 
Published: July 2013

Résumé.L'expression «métarégulation« décrit un mode de gouvernance transnationale des relations professionnelles, qui est le produit des efforts faits pour résoudre les contradictions entre les conventions collectives nationales et la liberté des Etats membres de l'UE de fournir des services et de détacher des travailleurs à l'étranger. La norme qui sous‐tend cette métarégulation est la concurrence non seulement entre les travailleurs des Etats membres de l'UE, mais aussi entre les réglementations du travail de ces derniers. Après avoir défini les concepts de «pouvoir structurel« et d' «espace social«, les auteurs commentent des cas empiriques illustrant la métarégulation progressive des relations professionnelles dans l'UE, et démontrent comment le rapport de forces asymétrique entre les travailleurs et le capital se creuse en faveur de ce dernier.
Emploi et salaires en Allemagne depuis la déréglementation du travail temporaire de 2004
Authors: GARZ Marcel 
Published: July 2013

Résumé.Depuis la déréglementation de 2004, on observe une explosion du travail temporaire en Allemagne. L'auteur procède à un examen empirique de la façon dont cette réforme a affecté l'emploi et les salaires. Après avoir contrôlé les effets de structure et d'ordre macroéconomique, il observe qu'il n'y a pas eu de changement du niveau général de l'emploi, le travail temporaire ayant remplacé des emplois réguliers. L'écart salarial entre travailleurs réguliers et travailleurs temporaires s'est creusé après la réforme, ce qui montre que les entreprises recourent au travail temporaire pour réduire le coût de la main‐d'œuvre. Toutefois, la principale raison de cet écart salarial est la plus forte fréquence des déterminants des faibles revenus chez les travailleurs temporaires.

Published: July 2013

Résumé.Les auteurs proposent une évaluation macroéconomique de certaines politiques actives du marché du travail en Espagne (notamment les aides aux contrats de durée indéterminée) à partir de données de panel sur les communautés autonomes (régions) pour la période 1987–2010. Les résultats indiquent que le subventionnement des contrats de durée indéterminée n'ont eu d'effet notable ni sur le niveau global de l'emploi ni sur celui du travail temporaire. Toutefois, on observe un faible effet positif sur les transitions du chômage au travail et du travail temporaire à l'emploi de durée indéterminée, cet effet étant supérieur après la réforme de 1997.

SummaryWhat is already known about this subject
Although there is no clear evidence of the role of dairy consumption on cardiovascular disease (CVD) risk development in adults, several studies have suggested dairy consumption to have a protective effect.
Limited evidence on the relationship between milk and dairy products consumption and CVD risk factors among adolescents.
What this study adds
Dairy consumption was inversely associated with CVD risk in European adolescent girls.
Higher dairy consumption was associated with lower adiposity and higher cardiorespiratory fitness in both genders.
ObjectiveTo identify those food groups best discriminating individuals at high/low cardiovascular disease (CVD) risk and to investigate the relationship between dairy consumption and CVD risk factors (individual and scores) in adolescents (12.5–17.5 years) from eight European cities participating in the cross‐sectional (2006–2007) HELENA (Healthy Lifestyle in Europe by Nutrition in Adolescence) project.MethodsDiet, waist circumference, skin‐folds thickness, systolic blood pressure, insulin resistance, triglycerides, total cholesterol/high‐density lipoprotein ratio and cardiorespiratory fitness (CRF) were assessed in 511 (49.9% boys) adolescents. Individual z‐scores of CVD risk factors were summed to compute sex‐specific clustered CVD risk scores.ResultsDairy emerged as the food group best discriminating adolescents at low/high CVD risk. In both genders, waist circumference and sum of skin‐folds were inversely associated with consumption of milk and yogurt, and milk‐ and yogurt‐based beverages, whereas a positive association was observed with CRF. Moreover, CVD risk score (β = −0.230, P = 0.001) was also inversely associated with overall dairy consumption only in girls.DiscussionDairy consumption is associated with lower adiposity and higher CRF in these adolescents. An inverse association between CVD risk score and dairy consumption is also depicted in girls. The study adds further evidence to the scarce literature on the influence of milk and dairy products on adolescents' cardiovascular health.

Published: July 2013

BackgroundHelping staff serving clients with intellectual disability and challenging behaviour to cope with stress has implications for their own well‐being and for the lives of those they support.MethodThis study examined staff members' views of stress and the effectiveness of a stress‐management intervention. Effectiveness was assessed using written assignments regarding stress management, and changes in views presented were tested in a pre‐ and post‐test control group design.ResultsIn the first phase, a content analysis was conducted across groups, which revealed that participants expressed a broad variety of views about stress and coping mechanisms, with considerable individual differences. In the second phase, a more fine‐grained quantitative analysis was conducted to assess training effectiveness. Results showed an increase in the proportion of coping strategies referred to by the experimental group post‐training. This positive change remained at follow‐up.ConclusionsThe results of the content analysis and the outcome data have implications for staff training.
Using Paleo Reconstructions to Improve Streamflow Forecast Lead Time in the Western United States

Published: July 2013

AbstractIn water stressed regions, water managers are exploring new horizons that would help in long‐range streamflow forecasts. Oceanic‐atmospheric oscillations have been shown to influence streamflow variability. In this study, long‐lead time streamflow forecasts are made using a multiclass kernel‐based data‐driven support vector machine (SVM) model. The extended streamflow records based on tree ring reconstructions were used to provide a longer time series data. Reconstructed data were used from 1658 to 1952 and the instrumental record was used from 1953 to 2007. Reconstructions for oceanic‐atmospheric oscillations included the El Niño‐Southern Oscillation, Pacific Decadal Oscillation, Atlantic Multidecadal Oscillation, and North Atlantic Oscillation. Streamflow forecasts using all four oscillations were made with one‐year to five‐year lead times for 21 gages in the western United States. This is the first study that uses both instrumental and reconstructed data of oscillations in SVM model to improve streamflow forecast lead time. SVM model was able to provide “satisfactory” to “very good” forecasts with one‐ to five‐year lead time for the selected gages. The use of all the oscillation indices helped in achieving better predictability compared to using individual oscillations. The SVM modeling results are better when compared with multiple linear regression model forecasts. The findings are statistical in nature and are expected to be useful for long‐term water resources planning and management.
Do Polynomials Adequately Describe the Hypsometry of Monadnock Phase Watersheds?
Authors: Vanderwaal James A. , Ssegane Herbert 
Published: July 2013

AbstractHypsometry has been shown to be a useful tool in geomorphic analysis of watersheds with the use of third‐degree polynomial equations to express the hypsometric curve. Despite its usefulness with watersheds in the equilibrium stage, the third‐degree polynomial has been found to be inadequate to describe the hypsometry of Monadnock phase watersheds. Three other equations — a modified third‐degree polynomial with a rational term, a sigmoidal model, and a double exponential — were used to determine hypsometric attributes of 32 Monadnock phase watersheds and compared to the third‐degree polynomial form. The three other equations were found to be better fits for Monadnock phase watersheds than the third‐degree polynomial equation, regardless of which ratio — area or elevation — was plotted as the independent variable. Due to the occasional failure of each functional form to give logical values for hypsometric attributes, the importance of using more than one form equation is discussed. After determining the best‐fit equation for each watershed, the usefulness of hypsometric attributes is discussed in relation to erosion processes within Monadnock phase watersheds.
A biogeographical regionalization of Australian Acacia species

Published: July 2013

AbstractAimTo develop a biogeographical regionalization of Australian Acacia species and to investigate their environmental correlates.LocationAustralia.MethodsWe used a previously published framework for delineating biogeographical regions. We calculated species turnover patterns of 1020 Australian Acacia species with distributions estimated from 171,758 georeferenced herbarium records aggregated to 100 km × 100 km cells (868 across Australia). An agglomerative cluster analysis using a matrix of pairwise Simpson's beta (βsim) dissimilarity values was applied. Eleven environmental variables at the same resolution as the aggregated herbarium records were used to explore the correlates of the βsim patterns using a non‐metric multidimensional scaling (NMDS) analysis. We also used an ANOVA to test the significance of the environmental changes between each pair of biogeographical regions.ResultsFive major Acacia biogeographical regions were proposed. These bioregions were broadly similar to the biomes of Australia. A new subdivision of the Eremaean biome was proposed for Acacia. The most influential environmental variables for the individual bioregions were: (1) temperature seasonality and topographic flatness for the south‐western temperate bioregion; (2) precipitation during the coldest quarter of the year for the south‐eastern temperate bioregion; (3) annual precipitation, annual mean temperature and precipitation seasonality for the monsoonal bioregion; and (4) percentage of sand in the top 30 cm of the soil, rock grain size, annual mean radiation and annual mean temperature for the Eremaean south and north regions. The NMDS analysis provided support for the observed biogeographical patterns. The statistical test showed a highly significant difference between the environments of the proposed bioregions. Climatic variables were consistent predictors across regions, whereas the influence of soils and topographic features varied among bioregions.Main conclusionsThe major Acacia biogeographical regions correspond well to historical bioregionalizations, suggesting that the environmental drivers of diversification in Acacia are broadly similar to those that act on the flora as a whole. Climate seasonality combined with annual values and non‐climatic factors provide support for the proposed biogeographical regionalization for Acacia.

AbstractAimTo characterize the changing fire regime of aMediterranean landscape during theHolocene and theLastInterglacial and, by comparing the two periods, to improve our understanding of the extent and timing of human alteration of natural fire regimes.LocationLake Ioannina, north‐westernGreece (39°45′ N, 20°51′ E).MethodsUsing a long sequence of lake sediments, we measured the charcoal content of the sediment over the course of theHolocene and theLastInterglacial. We compared the charcoal data with pollen data for the same periods.ResultsCharcoal was present in all samples analysed. Charcoal influx was greater during interglacials, which atIoannina were forested, than during glacials, when tree populations were small. Charcoal influx was greater and more variable during theHolocene than during theLastInterglacial.Main conclusionsFire was a persistent feature throughout the periods studied, under both glacial and interglacial conditions. Overall, more biomass was burned during interglacials than during glacials, and peak burning occurred at intermediate values of moisture availability. There is little evidence that the composition of forests significantly affected burning regimes. Enhanced burning during the Holocene relative to the Last Interglacial may reflect human impact, as well as climatic or vegetational differences between the two periods.

Variable Strategies for CTI Ablation ObjectivesThis study aimed to investigate the anatomical characteristics complicating cavotricuspid isthmus (CTI) ablation and the effectiveness of various procedural strategies.Methods and ResultsThis study included 446 consecutive patients (362 males; mean age 60.5 ± 10.4 years) in whom CTI ablation was performed. A total of 80 consecutive patients were evaluated in a preliminary study. The anatomy of the CTI was evaluated by multidetector row‐computed tomography (MDCT) prior to the procedure. A multivariate logistic regression analysis revealed that the angle and mean wall thickness of the CTI, a concave CTI morphology, and a prominent Eustachian ridge, were associated with a difficult CTI ablation (P < 0.01). In the main study, 366 consecutive patients were divided into 2 groups: a modulation group (catheter inversion technique for a concave aspect, prominent Eustachian ridge, and steep angle of the CTI or increased output for a thicker CTI) and nonmodulation group (conventional strategy). The duration and total amount of radiofrequency energy delivered were significantly shorter and smaller in the modulation group than those in the nonmodulation group (162.2 ± 153.5 vs 222.7 ± 191.9 seconds, P < 0.01, and 16,962.4 ± 11,545.6 vs 24,908.5 ± 22,804.2 J, P < 0.01, respectively). The recurrence rate of type 1 atrial flutter after the CTI ablation in the nonmodulation group was significantly higher than that in the modulation group (6.3 vs 1.7%, P = 0.02).ConclusionChanging the procedural strategies by adaptating them to the anatomical characteristics improved the outcomes of the CTI ablation.

AbstractBackgroundImpaired sleep in patients with moderate‐to‐severe psoriasis and improvement on therapy has not been widely studied.ObjectiveQuantify baseline aspects of sleep and improvement in patients with psoriasis receiving etanercept (ETN) when allowed concomitant topical medications (PRISTINE study).MethodsPatients with moderate‐to‐severe psoriasis were randomized to 50 mg ETN once weekly (QW/QW) or 50 mg ETN twice weekly (BIW/QW) for weeks 1–12, followed by 50 mg QW for weeks 13–24; a broad range of topical therapies were permitted during weeks 13–24. Sleep impairment was measured by the Medical Outcomes Study (MOS) sleep questionnaire Index II (population norm = 25.8; minimum clinically important difference = 5.1); quality of life (QoL) measures included Dermatology Life Quality Index (DLQI), EuroQoL 5 Dimension (EQ‐5D) Utility Index and Visual Analogue Scale (VAS) and Functional Activity in Chronic Therapy‐Fatigue (FACIT‐Fatigue). ancova and Fisher's exact test or chi‐squared tests were used for between‐group testing.ResultsMean baseline MOS‐Sleep scores were 34.0 for both groups indicating impairment (N = 270; QW/QW n = 137; BIW/QW n = 133, approximately 64% had impaired sleep). At week 12 of treatment, MOS‐Sleep scores improved to 30.8 and 30.1, and at week 24, to 28.4 and 28.2 respectively. Poor sleep was significantly associated with clinically important problems in EQ‐5D utility, VAS and FACIT‐Fatigue; sleep improvement was associated with improved EQ‐5D utility and FACIT‐Fatigue (P < 0.001).ConclusionThis study confirms that most patients with moderate‐to‐severe psoriasis have impaired sleep which is associated with impaired QoL. Treatment with etanercept significantly improved sleep, with most improvement occurring before a broad range of topicals were allowed. Sleep improvement was associated with improved QoL.

AbstractBackgroundThere are few data on the prevalence of obesity in the general psoriasis population and on the real impact of obesity on the management of psoriasis patients in the clinical setting.ObjectivesTo evaluate the prevalence of overweight and obesity in patients with moderate‐to‐severe psoriasis compared to the general population and to assess the relationship between Body Mass Index (BMI) and the risk of discontinuing treatment.MethodsPatients registered on Biobadaderm, a prospective registry, were grouped according the different categories of BMI and compared to the general Spanish population. Drug survival was analysed considering only drug withdrawal due to lack of effectiveness, remission and adverse events.ResultsA total of 1162 moderate‐to‐severe psoriasis patients on systemic conventional or biological treatment were recruited. The prevalence of obesity was found to be significantly higher in psoriasis patients than in the general Spanish population (P < 0.001). In multivariate analysis a 5‐unit increase in BMI, similar to a change in BMI category from normal weight to overweight and from overweight to obesity, was associated with a 12% increased risk of discontinuing therapy due to lack of effectiveness (HR 1.12, 95% CI: 1.01–1.24) and with a 17% increased risk of having an adverse event (HR 1.17, 95% CI: 1.02–1.36), both independently of the drug used.ConclusionsPatients with moderate‐to‐severe psoriasis had a higher prevalence of obesity than the general population. Increased BMI was associated with an increased risk of treatment discontinuation due to lack of effectiveness and a higher risk of adverse events.
