CAN WE IMPROVE MANAGEMENT PRACTICE OF FLOODPLAIN LAKES USING CLADOCERAN ZOOPLANKTON?
Authors: Kattel G. R. 
Published: May 2011

ABSTRACTNatural resource managers across Australia intend to promote healthy floodplain lake ecosystems with rich diversity and composition of biota because such ecosystems provide economically valuable services to society. However, management practice of these floodplain lake ecosystems is impeded by confounding effects of anthropogenic impacts and natural climate variability in recent decades. Yet, there are a few potential biological markers available that profoundly respond to ecological effects of climate change and human disturbances. Cladoceran zooplankton plays an intermediary role in food web dynamics. They show distinct responses to changes in temperature and environmental perturbations, such as acidification, nutrient loading and salinization. The effects of temperature and land‐use changes on food web dynamics and water quality, in particular, are major concerns for shallow lowland large river floodplain lakes management in Australia. Information on zooplankton assemblages and diversity can help increase our understanding of ecological processes in a wide range of environmental exposures. The study of cladoceran fossils and their ephippia preserved in floodplain lake sediment has substantially furthered our understanding of species–environment relationships at different temporal and spatial scales and allowed us to develop powerful inference models for degraded floodplain lake ecosystems. This consequently defines a benchmark of a shift from a naturally intact ecosystem to an ecologically poor regime. In this paper, I have made an attempt to persuade wetland managers through application of contemporary and palaeocladoceran communities to improve management practice of floodplain lake ecosystems in Australia by providing a range of examples.

Oil Content and Fatty Acid Profile of Spanish Cultivars During Olive Fruit Ripening
Authors: Gómez‐González S. , Ruiz‐Jiménez J. , Luque de Castro M. D. 
Published: May 2011

AbstractThe oils produced from five olive cultivars (i.e. arbequina, gordal, manzanilla, picual and picudo) and the evolution of fatty acid profile during olive fruit ripening were studied. The total oil content increased throughout ripening for Picudo cultivars; however, all other cultivars reached maximum oil contents between ripeness stage 2 and 4. The content of trans (0.3–5.8%), saturated (8.3–21.4%), monounsaturated (41.9–84.1%) and polyunsaturated fatty acids (2.3–49.7%) varied with the ripeness state and cultivar. Different trends of the different parameters were found as a function of the ripeness state and the cultivar. Statistical analysis reveal that manzanilla drupes, at the different ripeness states, are clearly different from the rest of the cultivars. In addition, there were no significant differences in the fatty acid profile of the oils obtained from drupes at ripeness states between 2 and 4.

Objectives To compare the underestimation of ductal carcinoma in situ (DCIS) vs DCIS with “possible invasion” at breast biopsy and to determine if any factors related to clinical indication, imaging abnormality, biopsy, or DCIS-grade affected the likelihood of underestimation. Methods Of 3836 consecutive lesions that were biopsied by using a 14-gauge needle, 117 lesions revealed DCIS. Surgical pathology results of invasive carcinoma were compared with needle biopsy results of DCIS or DCIS with possible invasion. Clinical indication, imaging abnormality, biopsy guidance modality, sample number, and histologic grade were recorded. Yates corrected χ2 and Fisher exact tests were used to determine differences between groups. Results A total of 101 lesions were DCIS and 16 were DCIS with possible invasion at biopsy. Thirty-six of 117 lesions (31%) revealed invasive carcinoma at resection pathology. Invasive carcinoma was present more often when DCIS with possible invasion was diagnosed compared with pure DCIS (7/16 [44%] vs 29/101 [29%], P = .36). No factor, including clinical indication, imaging abnormality, biopsy guidance method, sample number, or grade, was found to significantly affect the likelihood of underestimation for lesions diagnosed as DCIS vs DCIS with “possible invasion.” The likelihood of pure DCIS underestimation significantly increased when lesions were high grade compared with either intermediate or low grade (18/44 [41%] vs 9/44 [21%] vs 2/10 [20%], P = .03). Conclusion For lesions biopsied by using a 14-gauge needle, there is a trend towards underestimation of the presence of invasive carcinoma when pathology reveals DCIS with possible invasion compared with pure DCIS. High-grade DCIS was significantly more likely to be underestimated.

AbstractThe aim of this study was to evaluate the correlation among various preoperative clinical variables, including certain prostate needle biopsy parameters, biochemical failure, and adverse pathology, after radical retropubic prostatectomy (RRP). We retrospectively evaluated the records of our 156 patients who underwent RRP because of localized prostate cancer. Serum prostate‐specific antigen level, clinical stage, and the information obtained from biopsy [Gleason score, number of positive cores, percentage of positive cores (PPCs) from the dominant side of prostate, and overall PPC] were evaluated as predictors of adverse pathology and biochemical failure. Of the patients, 30.2% (n = 38) had nonorgan‐confined disease, 19.1% (n = 24) had positive surgical margins, 11.9% (n = 15) had positive seminal vesicle invasion, and 16.7% (n = 21) had biochemical failure after RRP. Multivariate analysis demonstrated that a PPC value of 55% or more from the dominant side of prostate is the only independent predictor of nonorgan‐confined disease and seminal vesicle invasion. Clinical stage (T2b), biopsy Gleason score, and PPC values of 55% or more from the dominant side of prostate were found to be statistically significant predictors of positive surgical margin and biochemical failure. Our results support that PPC from the dominant side of prostate is a useful parameter for the prediction of adverse pathology and biochemical failure after RRP.
Differentiation ofSolenopsis invictasocial forms using high resolution melt PCR

Published: May 2011

AbstractSolenopsis invictaBuren (red imported fire ant) are invasive pests that have the capability of major destructive impacts on lifestyle, ecology and economy. Control of this species is dependent, in part, upon ability to estimate the potential spread from newly discovered nests. The potential for spread and the spread characteristics differ between monogyne and polygyne social forms. Prior to this study, differentiation of the two social forms in laboratory test samples commonly used a method involving restriction endonuclease digestion of an amplifiedGp-9fragment. Success of this assay is limited by the quality of DNA, which in the field-collected insects may be affected by temporary storage in unfavourable conditions. Here, we describe an alternative and highly objective assay based upon a high resolution melt technique following preamplification of a significantly shorterGp-9fragment than that required for restriction endonuclease digestion. We demonstrate the application of this assay to aS. invictaincursion in Queensland, Australia, using field samples from which DNA may be partially degraded. The reductions in hands-on requirements and overall duration of the assay underpin its suitability for high-throughput testing.
MAKING THE PATIENT-CONSUMER IN MARGARET THATCHER'S BRITAIN
Authors: MOLD ALEX 
Published: May 2011

ABSTRACTThis article examines the role played by patient organizations in the making of the patient as consumer during Margaret Thatcher's term as prime minster. It details a crucial moment in the reconstitution of the relationship between state and citizen, as universal entitlements to welfare gave way to individualistic rights to, and choice of, services. Though patients had been regarded as consumers prior to this period, it was during the 1980s that the patient-consumer moved from the margins to centre-stage. By examining the activities of patient groups around three key themes – the provision of information, the development of patients' rights, and the notion of patient choice – this article shows that ideas about what it meant to be a patient-consumer came initially from patient groups. Through their work in these areas, patient groups built up a kind of patient consumerism that was concerned with the needs of the wider population, as well as representing demands made by individual patient-consumers. By the end of the 1980s, however, the patient-consumer was reconfigured by the Conservative government, and emphasis moved from the collective needs of patient-consumers to the rights of individuals within increasingly marketized services. This development thus raises questions not only about who speaks for the consumer, but also about the relationship between citizenship and consumption in contemporary Britain.
CONSULTATION AND CONSENT UNDER JAMES VI
Authors: MACDONALD ALAN R. 
Published: May 2011

ABSTRACTDivisions in the Scottish political community that were evident by the end of the reign of James VI have been posited as roots of the Scottish revolution of 1638 and the wars of the three kingdoms. This article argues that the disengagement of central government from the political nation at large was a key factor in this development. By demonstrating the frequency of conventions of the estates, it highlights the intensity of consultation in James's Scottish government before 1603. A sudden decline in their frequency thereafter was symptomatic of a wider failure of government to adapt to the absence of the king in the context of a composite monarchy. While correspondence between the king and the privy council was copious, communication between the council and the political elites of Scotland withered. Without conventions of the estates as a vital point of contact in which new policies could be tested and negotiated, parliaments became more disagreeable. The crown's reliance on unprecedented levels of management and increased central direction alienated a significant proportion of the political elite, driving them into the oppositional stance which endured through the reign of Charles I.
REPUBLICANISM, RAILWAY IMPERIALISM, AND THE FRENCH EMPIRE IN AFRICA, 1879–1889
Authors: ROBERTS T. W. 
Published: May 2011

ABSTRACTThis article questions accepted views of French expansion as a largely autonomous process, reflecting new attitudes towards Africa among policy-makers. It argues that the African railway schemes of 1879 were the outcome of an understanding between powerful railway interests and mainstream elements of the newly victorious republican parties. The ambitions of the railway companies were restricted in scope, however, being confined mainly to existing French possessions, while their sponsorship of imperial expansion was little more than a tactical expedient. It was only when the opportunities created for expansion were taken up by locally based pressure-groups or became caught up in international rivalries that empire began to take root in the Soudan and the Congo. By the time the anti-colonial reaction of the mid-1880s took hold, railway imperialism, a product of the short-lived economic boom, had already run its course. Government now had an opportunity and an incentive to put its imperial house in order. Nevertheless, the resulting equilibrium remained vulnerable to a re-emergence of the forces that had first set France on the road to empire in tropical Africa.
PLANNING THE URBAN FUTURE IN 1960s BRITAIN
Authors: ORTOLANO GUY 
Published: May 2011

ABSTRACTThis article recovers Buckinghamshire county council's proposal to build a monorail city for 250,000 residents during the 1960s. The project was eventually taken over by Whitehall, which proceeded to establish Britain's largest new town of Milton Keynes instead, but from 1962 to 1968 local officials pursued their monorail metropolis. By telling the story of ‘North Bucks New City’, the article develops a series of claims. First, the proposal should be understood not as the eccentric creation of a single British county, but rather as one iteration of larger state efforts to manage the densities and distributions of growing populations. Second, while the 1960s witnessed the automobile's decisive triumph as a means of personal mobility in Britain, that very triumph ironically generated critiques of the car and quests for alternatives. Third, the monorail was part of a complex social vision that anticipated – and, in part through the facilitation of recreational shopping, sought to alleviate – a crisis of delinquency expected to result from a world of automation and affluence. Fourth, despite its ‘futuristic’ monorail, the plan ultimately represented an effort by experts and the state to manage social change along congenial lines. Fifth, the proposal advanced a nationalist urbanism, promising renewed global stature for post-imperial Britain by building upon its long urban history. Finally, the article concludes by arguing that this unrealized vision points to the limitations of ‘modernism’ in the history of urban planning, and to the problems of teleology in the history of the 1960s.
PARANOIA AND PARTISANSHIP: GENOCIDE STUDIES, HOLOCAUST HISTORIOGRAPHY, AND THE ‘APOCALYPTIC CONJUNCTURE’
Authors: MOSES A. DIRK 
Published: May 2011

ABSTRACTRecent literature on the Holocaust and (other) genocides reveals that on the whole differences in approach persist. For many historians, as for the public, the Holocaust is the prototypical genocide, such that mass violence must resemble the Holocaust to constitute genocide. Whereas ‘normal’ ethnic/national conflict is commonly believed to involve ‘real’ issues like land, resources, and political power, no such conflict is discernible in the Holocaust of European Jewry, whose victims were passive and agentless objects of the ‘hallucinatory’ ideology of the perpetrators. But is this distinction sustainable on closer inspection? This review suggests that genocide is mistakenly identified as a massive hate crime based entirely on ‘race’. In fact, it has a political logic: irrational or at least exaggerated fears about subversion and national or ‘ethnic’ security. Prejudices do not cause violence: they are mobilized in conditions of emergency. Recent research tends in this direction by emphasizing paranoia rather than racism in the anti-Jewish policies of the Nazis but does not transcend the customary distinction between the ‘delusional’ grounds for the former and ‘real’ ethnic conflict. This separation of categories feeds into the anxieties in some contributors to this literature about potential genocides in the present by forecasting apocalyptic scenarios unless drastic military action is taken against specified enemies. Scholarship is better served by deflating rather than inflating such anxieties.

AbstractA survey of the occurrence of Dirofilaria immitis, Borrelia burgdorferi, Ehrlichia canis and Anaplasma phagocytophium in dogs was undertaken in the People's Republic of China between October 2008 and October 2009. A total of 600 blood samples were taken from dogs in four cities in China: 300 in Beijing, 150 in Shenzhen, 30 in Shanghai and 120 in Zhengzhou. All samples were tested for the heartworm antigen and antibodies of canine B. burgdorferi, E. canis and A. phagocytophium by using the canine SNAP® 4Dx® test kit. The occurrence of D. immitis, B. burgdorferi, E. canis and A. phagocytophium was 1.17% (7/600), 0.17% (1/600), 2.17% (13/600) and 0.5% (3/600), respectively. In Shenzhen city 2% (3/150), 8.67% (13/150) and 2% (3/150) of samples were positive for D. immitis, E. canis and A. phagocytophium, respectively. The occurrence of heartworm antigen was 0.33% (1/300) in Beijing, 2.00% (3/150) in Shenzhen, 3.33% (1/30) in Shanghai and 1.67% (2/120) in Zhengzhou. We found E. canis and A. phagocytophium only at one site, Shenzhen, while the only occurrence of B. burgdorferi was at Beijing. In conclusion, the dog population in China is at potential risk for D. immitis, B. burgdorferi, E. canis and A. phagocytophium infection, the risk being especially high in southern China.
Wehrmacht occupations in the new world: archaeological and historical investigations in Northeast Greenland
Authors: Jensen Jens Fog , Krause Tilo 
Published: May 2011

ABSTRACTAs the axis powers were denied access to data from international weather stations under allied control, soon after the outbreak of World War II Germany had to establish her own network of manned and automatic weather stations throughout the north Atlantic. These operations were primarily run by the Kriegsmarine and the Luftwaffe. In Greenland, several manned weather stations were established by the former. The two most successful of those were Holzauge and Bassgeiger in Northeast Greenland, each in operation for almost an entire year in 1942–1943 and 1943–1944 respectively. The allied forces, in return, had established the North-East Greenland Sledge Patrol in 1941, in order to defend the Northeast Greenland coast against German activities. In 2007 and 2008, archaeologists and historians from the National Museum of Denmark investigated the remains of the allied station at Eskimonæs on Clavering Ø (Clavering Island) and the German station Holzauge at Hansa Bugt on Sabine Ø (Sabine Island).
Child-, adolescent- and young adult-onset depressions: differential risk factors in development?
Authors: Shanahan L. , Copeland W. E. , Costello E. J. , Angold A. 
Published: May 2011

BackgroundPrevious research reported that childhood adversity predicts juvenile- onset but not adult-onset depression, but studies confounded potentially genuine differences in adversity with differences in the recency with which adversity was experienced. The current study paper took into account the recency of risk when testing for differences among child-, adolescent- and young adult-onset depressions.MethodUp to nine waves of data were used per subject from two cohorts of the Great Smoky Mountains Study (GSMS;n=1004), covering children in the community aged 9–16, 19 and 21 years. Youth and one of their parents were interviewed using the Child and Adolescent Psychiatric Assessment (CAPA) between ages 9 and 16; these same youth were interviewed using the Young Adult Psychiatric Assessment (YAPA) at ages 19 and 21. The most common psychosocial risk factors for depression were assessed: poverty, life events, parental psychopathology, maltreatment, and family dysfunction.ResultsConsistent with previous research, most childhood psychosocial risk factors were more strongly associated with child-onset than with adolescent-/adult-onset depression. When potentially genuine risk differences among the depression-onset groups were disentangled from differences due to the recency of risk, child- and young adult-onset depression were no longer different from one another. Adolescent-onset depression was associated with few psychosocial risk factors.ConclusionsThere were no differences in putative risk factors between child- and young adult-onset depression when the recency of risk was taken into account. Adolescent-onset depression was associated with few psychosocial risk factors. It is possible that some adolescent-onset depression cases differ in terms of risk from child- and young adult-onset depression.

AbstractAlthough mature seeds of the monogeneric conifer family Cephalotaxaceae sensu stricto have underdeveloped embryos, no definitive studies have been done to classify dormancy in this family. Our primary purpose was to determine the kind of dormancy in seeds of Cephalotaxus wilsoniana and to put the results into a broad phylogenetic context for gymnosperms. The species is of horticultural and medicinal value, and information is needed on how to propagate it efficiently from seeds. Embryo growth and germination were monitored for seeds at warm, cold and warm plus cold temperatures, and germination was monitored for seeds subjected to: (1) cold → warm → cold → warm; and (2) warm → cold → warm → cold → warm temperature sequences. The effects of gibberellic acids GA3 and GA4 were tested on radicle emergence in ungerminated seeds and on shoot emergence in root-emerged seeds. Germination was promoted by ≥ 36 weeks of warm stratification followed by ≥ 8 weeks of cold stratification, but only if seeds were returned to high temperatures. The underdeveloped embryo must increase in length by >120% before the radicle emerges. Neither GA3 nor GA4 was effective in promoting radicle emergence; however, both plant growth regulators increased rate (but not percentage) of shoot emergence in root-emerged seeds. We conclude that seeds of C. wilsoniana have the deep simple level of morphophysiological dormancy (MPD), C1b-C3-B1b; thus, warm stratification followed by cold stratification and then warm-temperature incubation are required for germination. In gymnosperms, MPD is known in cycads, Ginkgo and now in three families of conifers.

SummaryIn vitro folliculogenesis could be a new technology to produce mature oocytes from immature follicles that have been isolated from cryopreserved or fresh ovarian tissue. This technique could also be a tool for evaluation of oocyte quality and/or for determination of follicular parameters during follicular growth. Our objective was to characterize in mice the secretion profiles of follicles that had been isolated mechanically during in vitro follicular growth and in relation to the growth curve. Early preantral follicles from fresh prepubertal and adult mouse ovaries or frozen–thawed prepubertal mouse ovaries were cultured individually in microdrops under oil for 12 days. Each day, two perpendicular diameters of the follicles were measured. From day-3 to day-12 of culture, culture medium was collected and preserved for determination of inhibin B, anti-Müllerian hormone (AMH) and estradiol levels. At the end of the culture, after maturation, the status of the oocyte was evaluated. Follicular growth and their individual hormone production did not always correlate. Inhibin B was never secreted from follicles of less than 200 μm diameter, whether the follicles were examined when fresh or after freezing–thawing. Estradiol secretion was never observed in frozen–thawed follicles. AMH was mainly secreted between day-3 and day-9. Despite similar morphological aspects at the start of culture, follicles selected for in vitro folliculogenesis were found to be heterogeneous and differed in their ability to grow and to produce hormones, even if they had similar growth curves. Follicles from frozen–thawed ovaries developed slowly and produced fewer hormones than freshly collected follicles.
