Many routes lead to Rome : potential causes for the multi-route migration system of Red Knots, Calidris canutus islandica

Migrants, such as birds or representatives of other taxa, usually make use of several stopover sites to cover the distance between their site of origin and destination. Potentially, multiple routes exist, but often little is known about the causes and consequences of alternative migration routes. Apart from their geographical distribution, the suitability of potential sites might play an important role in the animals’ decisions for a particular itinerary. We used an optimal-migration model to test three nonmutually exclusive hypotheses leading to variations in the spring migration routes of a subspecies of Red Knot, Calidris canutus islandica, which migrates from wintering grounds in Western Europe to breeding grounds in Greenland and the Canadian Arctic: the breeding location hypothesis, the energy budget hypothesis, and the predation risk hypothesis. Varying only breeding location, the model predicted that birds breeding in the Canadian Arctic and on West Greenland stop over on Iceland, whereas birds breeding in East and Northeast Greenland migrate via northern Norway, a prediction that is supported by empirical findings. Energy budgets on stopover sites had a strong influence on the choice of route and staging times. Varying foraging-intensity and mass-dependent predation risk prompted the birds to use less risky sites, if possible. The effect of simultaneous changes in the energy budget and predation risk strongly depended on the site where these occurred. Our findings provide potential explanations for the observations that C. canutus islandica uses a diverse array of migration routes. Scrutinizing the three alternative driving forces for the choice of migratory routes awaits further, specific data collection in rapidly developing fields of research (e.g., predation risk assessment, GPS tracking). Generally, the type of modeling presented here may not only highlight alternative explanations, but also direct follow-up empirical research.

The consequences of climate-driven stop-over sites changes on migration schedules and fitness of Arctic geese

1. How climatic changes affect migratory birds remains difficult to predict because birds use multiple sites in a highly interdependent manner. A better understanding of how conditions along the flyway affect migration and ultimately fitness is of paramount interest.

2. Therefore, we developed a stochastic dynamic model to generate spatially and temporally explicit predictions of stop-over site use. For each site, we varied energy expenditure, onset of spring, intake rate and day-to-day stochasticity independently. We parameterized the model for the migration of pink-footed goose Anser brachyrhynchus from its wintering grounds in Western Europe to its breeding grounds on Arctic Svalbard.

3. Model results suggested that the birds follow a risk-averse strategy by avoiding sites with comparatively high energy expenditure or stochasticity levels in favour of sites with highly predictable food supply and low expenditure. Furthermore, the onset of spring on the stop-over sites had the most pronounced effect on staging times while intake rates had surprisingly little effect.

4. Subsequently, using empirical data, we tested whether observed changes in the onset of spring along the flyway explain the observed changes in migration schedules of pink-footed geese from 1990 to 2004. Model predictions generally agreed well with empirically observed migration patterns, with geese leaving the wintering grounds earlier while considerably extending their staging times in Norway.

Putting the Australian Labor Party in international perspective

This paper assesses the Australian Labor Party's current debates over future directions with reference to attempts by the left of centre political parties in other western nations, especially in Western Europe, to deal with the end of the economic "golden age" since the early 1970s and the widespread resurgence of neo-liberal ideologies since the late 1970s. The dominant recent view of such comparisons has been through the ideological lens of the "Third Way". This vision however tends not to see relevant variations between the experiences of social democratic parties in individual Western European nations as they have sought to deal with adverse circumstances since the early 1970s. Nor does the Third Way view sufficiently extend to the widely varying background landscapes: that is, the different levels of historical achievement by left of centre parties in the different nations. Some social democratic parties in European countries are pursuing more progressive political agendas than the British Labour Party under Tony Blair and they are starting from a very different basis of policy achievement and political strength than either the British or Australian labour parties. The nature and extent of these international differences need now to be highlighted from an Australian political perspective in order to better inform the current debate about the range of options for the ALP and the current comparative condition of the Australian party system. As part of this analysis, the relationship between the erosion of the traditional blue-collar support bases of the major left of centre parties in various nations, amid economic restructuring and challenges to traditional immigration patterns, and the rise of support for anti-immigrant policies and parties, need to be carefully examined and evaluated.

Distribution, extent of inter-annual variability and diet of the bloom-forming jellyfish Rhizostoma in European waters

Jellyfish (Cnidaria: Scyphozoa) are increasingly thought to play a number of important ecosystem roles, but often fundamental knowledge of their distribution, seasonality and inter-annual variability is lacking. Bloom forming species, due to their high densities, can have particularly intense trophic and socio-economic impacts. In northern Europe it is known that one particularly large (up to 30 kg wet weight) bloom forming jellyfish is Rhizostoma spp. Given the potential importance, we set out to review all known records from peer-reviewed and broader public literature of the jellyfish R. octopus (Linnaeus) and R. pulmo (Macri) (Scyphozoa: Rhizostomae) across western Europe. These data revealed distinct hotspots where regular Rhizostoma spp. aggregations appeared to form, with other sites characterized by occasional abundances and a widespread distribution of infrequent observations. Surveys of known R. octopus hotspots around the Irish Sea also revealed marked inter-annual variation with particularly high abundances forming during 2003. The location of such consistent aggregations and inter-annual variances are discussed in relation to physical, climatic and dietary variations.

Reassortant highly pathogenic influenza a H5N2 virus containing gene segments related to eurasian H5N8 in British Columbia, Canada, 2014

In late November 2014 higher than normal death losses in a meat turkey and chicken broiler breeder farm in the Fraser Valley of British Columbia initiated a diagnostic investigation that led to the discovery of a novel reassortant highly pathogenic avian influenza (HPAI) H5N2 virus. This virus, composed of 5 gene segments (PB2, PA, HA, M and NS) related to Eurasian HPAI H5N8 and the remaining gene segments (PB1, NP and NA) related to North American lineage waterfowl viruses, represents the first HPAI outbreak in North American poultry due to a virus with Eurasian lineage genes. Since its first appearance in Korea in January 2014, HPAI H5N8 spread to Western Europe in November 2014. These European outbreaks happened to temporally coincide with migratory waterfowl movements. The fact that the British Columbia outbreaks also occurred at a time associated with increased migratory waterfowl activity along with reports by the USA of a wholly Eurasian H5N8 virus detected in wild birds in Washington State, strongly suggest that migratory waterfowl were responsible for bringing Eurasian H5N8 to North America where it subsequently reassorted with indigenous viruses.

Population prevalence of personality disorder and associations with physical health comorbidities and health care service utilization: a review

Personality disorder (PD), outcomes of diverse comorbid physical health conditions, and the associated burden on health service resources have seldom been studied at a population level. Consequently, there is limited evidence that might inform a public health approach to managing PD and associated mental and physical disability. A review was conducted of population-based studies examining the prevalence of PD and associations between physical comorbidities and service utilization. The prevalence of any PDs were common (4.4% -21.5%) among populations spanning England, Wales, Scotland, Western Europe, Norway, Australia, and the United States. Preliminary evidence supports associations between PDs from Clusters A and B and physical comorbidities, namely cardiovascular diseases and arthritis. PD appears to increase health care utilization, particularly in primary care. In order to facilitate rational population health planning, further population studies are required.

The roots of punitive damages at common law: a longer history

This Article aims to revisit the historical development of the doctrine ofexemplary or punitive damages. Punitive damages are anomalous in that they lie in both tort and crime, a matter that has led to much criticism by modern commentators. Yet, a definitive history of punitive damages does not exist to explain this anomaly. The main contribution of this Article, then, is to begin such a history by way of a meta-narrative. It identifies and links the historically significant moments that led to punitive damages, beginning with the background period of classical Roman law, its renewed reception in Western Europe in the twelfth and thirteenth centuries that coincided with the emergence of the English common law,the English statutes of the late thirteenth century, to the court cases of Wilkes v. Wood and Huckle v. Money in the eighteenth century that heralded the "first explicit articulation" of the legal principle of punitive damages. This Article argues that this history is not linear in nature but historically contingent. This is a corrective to present scholarship, which fails to adequately connect or contextualize these historical moments, or over-simplifies this development over time.

Early Carboniferous spiriferoid brachiopods from the Qaidam Basin, Northwest China: taxonomy, biostratigraphy and biogeography

Six Early Carboniferous brachiopod species in four genera of the Superfamily Spiriferoidea are described from the Qaidam Basin, northwestern China, including a new genus, Qaidamospirifer, and two new species: Grandispirifer qaidamensis and Qaidamospirifer elongatus. Additionally, a new genus, Triangulospirifer, is also proposed to replace Triangularia (Poletaev, 2001) that was preoccupied by a Devonian molluscan genus.

On the basis of the new material as well as published information, we have reviewed the taxonomic composition and the stratigraphic and palaeobiogeographic distributions of the three previously established genera from the viewpoint of palaeobiogeography. The study reveals that Grandispirifer has a relatively long stratigraphic range from the late Tournaisian to Serpukhovian. During this interval, the genus attained a wide geographical distribution, reaching Northwest China, western Yunnan of West China, Japan, as well as Iran and North Africa. Angiospirifer first occurred in western Europe in the Viséan, and later migrated to North Africa during the late Viséan. In the Serpukhovian, it migrated eastward, reaching the Donets Basin of Ukraine and the Qaidam Basin in Northwest China. Anthracothyrina evolved from Brachythyrina in North Africa in late Viséan, then dispersed north-westward to western and eastern Europe and, further eastward to the Qaidam Basin during the Serpukhovian.

Measuring message framing effects across Europe

This study examines consumer response to positively versus negatively framed advertising messages across seven Central and Western European countries. The frames elicited significantly different emotional, cognitive and attitudinal reactions. Groups of nations where consumers responded more homogeneously to the frames were different from the groups plotted according to cultural context. In addition, the results present a new perspective for international marketing. While advertising content and imagery has often been designed to account for known or assumed differences across nations, the findings of this study show that neglecting even subtle national differences can be misleading and can result in adverse consequences. The study has shown that consumers in similar countries, such as Poland, Czech Republic and Hungary, respond quite differently to positively or negatively framed advertisements. This suggests that even advertising campaigns that are designed for relatively narrow international audiences may not be effective when featuring an inappropriate message frame.

Nietzsche as 'Europe's Buddha' and 'Asia's superman'

Nietzsche represents in an interesting way the well-worn Western approach to Asian philosophical and religious thinking: initial excitement, then neglect by appropriation, and swift rejection when found to be incompatible with one’s own tradition, whose roots are inexorably traced back to the ‘ancient’ Greeks. Yet, Nietzsche’s philosophical critique and methods - such as ‘perspectivism’ - offer an instructive route through which to better understand another tradition even if the sole purpose of this exercise is to perceive one’s own limitations through the eyes of the other: a self-destruktion of sorts. To help correct this shortcoming and begin the long overdue task of even-handed dialogue - or contemporary comparative philosophy - we will be served well by looking at Nietzsche’s mistakes, which in turn informed the tragic critic of the West of the last century, Martin Heidegger. We may learn here not to cast others in one’s own troubled image; and not to reverse cultural icons: Europe’s Superman, and Asia’s Buddha.

Variation in age and physical status prior to total knee and hip replacement surgery : a comparison of centers in Australia and Europe

Objective : To investigate whether variation exists in the preoperative age, pain, stiffness, and physical function of people undergoing total knee replacement (TKR) and total hip replacement (THR) at several centers in Australia and Europe.
Methods : Individual Western Ontario and McMaster Universities Osteoarthritis Index data (range 0-100, where 0 = best and 100 = worst) collected within 6 weeks prior to primary TKR and THR were extracted from 16 centers (n = 2,835) according to specified eligibility criteria. Analysis of covariance was used to evaluate differences in pain, stiffness, and physical function between centers, with adjustment for age and sex.
Results : There was marked variation in the age of people undergoing surgery between the centers (TKR mean age 67-73 years; F[6,1004] = 4.21, P < 0.01, and THR mean age 63-72 years; F[14,1807] = 7.27, P < 0.01). Large differences in preoperative status were observed between centers, most notably for pain (TKR adjusted mean pain 52.5-61.1; F[6,1002] = 4.26, P < 0.01, and THR adjusted mean pain 49.2-65.7; F[14,1802] = 8.44, P < 0.01) and physical function (TKR adjusted mean function 52.7-61.4; F[6,1002] = 5.27, P < 0.01, and THR adjusted mean function 53.3-71.0; F[14,1802] = 6.71, P < 0.01). Large effect sizes (up to 0.98) reflect the magnitude of variation between centers and highlight the clinical relevance of these findings.
Conclusion : The large variations in age and preoperative status indicate substantial differences in the timing of joint replacement across the centers studied, with potential for compromised surgical outcomes due to premature or delayed surgery. Possible contributing factors include patient preferences, the absence of concrete indications for surgery, and the capacity of the health care systems.

The Copenhagen school on your in Kyrgyzstan : is securitization theory useable outside Europe?

The article argues that the theoretical framework presented by the Copenhagen School is currently unsuited to empirical studies outside the West owing to two factors. First, the presence of the ‘Westphalian straitjacket’ has prevented explicit interrogation of the normative concepts underlying the framework: there is a presumption that European understandings of society and the state are universal. Second, the centrality of the speech-act for securitization to the exclusion of other forms of expression, such as physical action, results in the theoretical framework producing a Westernized description of a given situation. The extent to which these factors limit the utility of the concepts of securitization and societal security in a non-Western setting is illustrated through the case of the overthrow of the government in Kyrgyzstan in March 2005. This example forms an empirical critique to highlight how theoretical shortcomings result in a simplified and Westernized description of the situation that does not take into account the specific local socio-political context. The article concludes that if the Copenhagen School’s theoretical framework is to be considered suitable for universal application, future theoretical developments must explicitly address the issues discussed to enable progress in escaping International Relations’ Westphalian straitjacket.
