Safe2Tell®: An anonymous, 24/7 reporting system for preventing school violence
Authors: Payne Susan R. T. , Elliott Delbert S. 
Published: April 2011

AbstractThere is widespread agreement that many school shootings could be prevented if authorities were informed that a student was planning or preparing to carry out an attack. A universal problem is that young people are highly reluctant to report on their peers. This code of silence represents a major barrier to prevention efforts. In response to the Columbine shooting, the state of Colorado established the Safe2Tell® anonymous, 24/7 reporting system for receiving and forwarding threats of violence, bullying, and other concerns. This article describes how the program has grown to the point that it now receives more than 100 calls per month. A series of case examples illustrates its success in responding to threatening situations, including twenty‐eight potential school attacks.
Is There Any Value Investigating Persistent Haematospermia? Results of a 12-Year Prospective Study
Authors: Kumar Ashish A. , Zachariah Kuruvilla K. , Dorkin Trevor J. 
Published: April 2011

Objectives: We hypothesise that haematospermia, with no additional clinical features and regardless of age, does not warrant investigation as abnormal pathology is rarely found. Patients and methods: Twelve-year prospective data were collected on men referred with persistent haematospermia. Patients were divided into two age groups: less than 40 years and greater than 40 years. Patients were assessed through history and clinical examination including a DRE, serum PSA and a TRUS — with or without biopsy. Results: Fourteen men under 40 presented with haematospermia. TRUS showed calcification in 2 patients. No malignancy was detected in this sub-group. Conclusion: Mono-symptomatic haematospermia — regardless of age — requires only limited investigation as the condition is invariably benign. Prostate biopsies should only be considered if an elevated PSA and/or abnormal DRE are detected.
Understanding fear of pain in chronic pain: Interoceptive fear conditioning as a novel approach

Published: April 2011

AbstractThe current review deals with interoceptive conditioning as a viable mechanism maintaining fear of pain: The available literature suggests that interoceptive—i.e., internal bodily—sensations may become predictors of pain and will subsequently elicit fear of pain.After a short overview of interoceptive (fear) conditioning and its role in the maintenance of panic disorder, the existing literature on conditioning in the field of pain and fear of pain is reviewed. Next, the authors propose an interoceptive fear conditioning model of fear of pain, suggesting that bodily sensations can function as predictors of pain and as conditioned stimuli become endowed with the capacity to elicit an (anticipatory) fear response.The review concludes with a number of theoretical and clinical considerations, introducing interoceptive exposure as a potentially effective treatment for fear of pain.
Factors associated with hospitalisation of patients with schizophrenia in four European countries
Authors: Gorwood P. 
Published: April 2011

AbstractPurposeTo analyse factors associated with hospitalisation in patients with schizophrenia from four European countries, and to investigate whether national specificities might have an impact on the profile of inpatients.MethodA randomly selected sample of psychiatrists (N = 744), from Germany, Greece, Italy and Spain, collected data on the five last patients with schizophrenia they had seen in consultation (N = 3996).ResultsHigh positive symptoms, lack of insight, not living with the family, frequent past episodes, addiction to illegal drugs, global severity, uncooperativeness and smoking were significantly associated with hospitalisation, with OR between 4.1 and 1.26. Nevertheless, only high positive symptoms from the PANSS and lack of insight were systematically detected in the four countries. Among different results, the weight of “not living with the family” had national specificities, as Germany was the only country where this factor played no role (OR = 0.94).ConclusionAlthough some factors such as positive symptoms are associated with hospitalisation in a very homogenous way throughout different countries, discrepancies were detected between countries, for “living with the family”, “number of past acute relapses” and “uncooperativeness”. Linking these specificities to national healthcare systems might be useful to promote access to care for all patients.
Timing and duration of North American glacial lake discharges and the Younger Dryas climate reversal

Published: April 2011

AbstractRadiocarbon-dated sediment cores from the Champlain Valley (northeastern USA) contain stratigraphic and micropaleontologic evidence for multiple, high-magnitude, freshwater discharges from North American proglacial lakes to the North Atlantic. Of particular interest are two large, closely spaced outflows that entered the North Atlantic Ocean via the St. Lawrence estuary about 13,200–12,900 cal yr BP, near the beginning of the Younger Dryas cold event. We estimate from varve chronology, sedimentation rates and proglacial lake volumes that the duration of the first outflow was less than 1 yr and its discharge was approximately 0.1 Sv (1 Sverdrup = 106 m3 s−1). The second outflow lasted about a century with a sustained discharge sufficient to keep the Champlain Sea relatively fresh for its duration. According to climate models, both outflows may have had sufficient discharge, duration and timing to affect meridional ocean circulation and climate. In this report we compare the proglacial lake discharge record in the Champlain and St. Lawrence valleys to paleoclimate records from Greenland Ice cores and Cariaco Basin and discuss the two-step nature of the inception of the Younger Dryas.
Kinematics of rock flow and fabric development associated with shear deformation within the Zagros transpression zone, Iran
Authors: FAGHIH ALI , SARKARINEJAD KHALIL 
Published: April 2011

AbstractThis paper presents quantitative data on the finite strain, quartz crystal fabric, geometry of flow and deformation temperatures in deformed quartzite samples to characterize the ductile deformation along the thrust sheets constituting the Sanandaj–Sirjan Metamorphic Belt within the Zagros Mountains of Iran. The results of this study emphasize the heterogeneous nature of deformation in this belt, showing a spatial variation in strain magnitude and in degree of non-coaxiality. A dominant top-to-the-SE sense of shear is indicated by the asymmetry of microstructures and quartz c-axis fabrics. Quartz c-axis opening angles suggest deformation temperatures range between 435° ± 50°C and 510° ± 50°C, which yield greenschist to amphibolite facies conditions during the ductile deformation. Mean kinematic vorticity number (Wm) measured in the quartzite samples ranges between 0.6 and 0.9 with an average of 0.76, which indicates that extrusion of the metamorphic rocks of the region was facilitated by a significant component of pure shear strain. Traced towards the basal thrust of the Zagros Thrust System from northeast to southwest, the quartz grain fabrics change from asymmetric cross-girdle fabrics in the internal part of the deformation zone to an asymmetric single-girdle fabric at distances close to the basal thrust. This variation may depend on the structural depth and on the geometry of the ductile deformation zone. The observed increase in strain and vorticity within the study area is comparable with patterns recorded within metamorphic rock extrusions within other orogens in the world.
Struggles for Individual Rights and the Expansion of the International System
Authors: Reus-Smit Christian 
Published: April 2011

AbstractWe live today in the world's first universal, multicultural, and multiregional system of sovereign states. Five centuries ago, emergent sovereign states were confined to Europe and contained within the bounds of Latin Christendom. Through five great waves of expansion this nascent European system globalized. The Westphalian settlement, the independence of Latin America, the Versailles settlement, post-1945 decolonization, and the collapse of the Soviet Union each brought a host of new states into the system. How can we explain these great waves of expansion, each of which saw imperial systems of rule displaced by the now universal form of the sovereign state? After detailing the limits of existing explanations, this article presents a new account of the principal waves of systemic expansion that stresses the importance of subject peoples' struggles for the recognition of individual rights. Empires are hierarchies, the legitimacy of which has been sustained historically by traditional regimes of unequal entitlements—institutional frameworks that allocate individuals of different social status different social powers and entitlements. In the Westphalian, Latin American, and post-1945 waves of expansion, which together produced most of today's sovereign states and gave the system its principal regions, subject peoples embraced local interpretations of new, distinctly modern ideas about individual rights and challenged the traditional distribution of entitlements that undergirded imperial hierarchy. Each wave differed, not the least because different rights were at work: liberty of religious conscience, the right to equal political representation, and after 1945, a compendium of civil and political rights. But in each case a “tipping point” was reached when the imperial system in question proved incapable of accommodating the new rights claims and subject peoples turned from “voice” to “exit,” and each time the sovereign state was seen as the institutional alternative to empire.
The Reductionist Gamble: Open Economy Politics in the Global Economy
Authors: Oatley Thomas 
Published: April 2011

AbstractInternational political economy (IPE) should transition to “third-wave” scholarship because Open Economy Politics (OEP), which dominates current American IPE scholarship, can generate inaccurate knowledge. OEP can produce inaccurate knowledge because it studies domestic politics in isolation from international or macro processes. This methodological reductionism is often inappropriate for the phenomena IPE studies because governments inhabit a complex social system. As a result, the political choices that OEP strives to explain are typically a product of the interplay between domestic politics and macro processes. When OEP omits causally significant macro processes from empirical models, the models yield biased inferences about the domestic political relationships under investigation. Although scholars tolerated such errors when the gains from OEP were large, these errors are less tolerable now that OEP has matured. Consequently, the field should transition toward research that is nonreductionist, problem-driven, and pluralistic.
Exit Bismarck, Enter Dualism? Assessing Contemporary German Labour Market Policy
Authors: CLASEN JOCHEN , GOERNE ALEXANDER 
Published: April 2011

AbstractBetween 2003 and 2005, German labour market policy was subjected to the most far-reaching reform since the 1960s. Some commentators have interpreted the changes introduced as signalling a departure from the traditional ‘Bismarckian’ paradigm in German social policy. For others, the new legislation has contributed and consolidated an ever-more pervasive trend of dualisation within the German welfare state. In this article, we contest both interpretations. First, we demonstrate that traditional social insurance principles remain a dominant element within unemployment protection. Second, we show that German labour market policy is less rather than more segmented today than it was a decade ago.
Acquiring diglossia: mutual influences of formal and colloquial Arabic on children's grammaticality judgments
Authors: KHAMIS-DAKWAR REEM , FROUD KAREN , GORDON PETER 
Published: April 2011

ABSTRACTThere are differences and similarities between Modern Standard Arabic (MSA) and spoken varieties of Arabic, in all language domains. To obtain preliminary insights into interactions between the acquisition of spoken and standard varieties of a language in a diglossic situation, we employed forced-choice grammaticality judgments to investigate morphosyntactic knowledge of MSA and the local variant of Palestinian Colloquial Arabic (PCA), in 60 Arabic-speaking children aged 6 ; 4 to 12 ; 4, from a school in Nazareth. We used morphosyntactic structures which either differed or were similar between PCA and standard Arabic. Children generally performed better on items presented in PCA than in standard Arabic, with the exception of constructions involving negation. Children performed better on items when the two constructions were similar in both language varieties. We discuss the results with respect to the multiple factors that affect acquisition in a diglossic situation, and relate our findings to the possibility of interference effects of diglossia on learning.
Human beings are highly susceptible to low doses of Trichinella spp.

Published: April 2011

SUMMARYTrichinella is an important foodborne pathogen causing considerable morbidity and mortality. To prevent human trichinellosis, meat inspection for Trichinella spp. at slaughter is a key instrument. Current testing is based on minimal infectious dose in humans, but a scientific basis for this approach is lacking. To this end, a dose–response model must be developed, allowing translation of exposure into disease burden at the population level. We developed novel methods for dose–response assessment using outbreak data incorporating sexual reproduction of the parasite. A selection of suitable outbreak studies, reporting numbers exposed and infected, as well as estimated doses, was collated from a literature study. Humans appear to be highly susceptible: exposure to low doses (few larvae) is associated with a considerable risk of infection. As a consequence, levels of Trichinella in meat must be low to maintain acceptable health risks.

SUMMARYNoroviruses are, after rotaviruses, the second most common causative agents of acute gastroenteritis in young children. We studied norovirus genotypes in faecal specimens collected from Finnish children followed-up prospectively in rotavirus vaccine trials. Almost 5000 faecal specimens collected from cases of acute gastroenteritis were examined using reverse transcriptase–PCR. A total of 1172 cases (25% of all acute gastroenteritis) were associated with noroviruses. Of these, 96% were genogroup GII. GII.4 was the most common genotype (46%) throughout the study period but the proportion of this genotype varied in different norovirus epidemic seasons. Additional norovirus genotypes detected were: GII.7 (15%), GII.3 (14%), GII.1 (9%), GII.b (7%), GII.2 (3%), and GI.3 (2%). GII.4 dominated during the following years: 1998–1999 (75%), 2002–2003 (88%) and 2006–2007 (98%) while recombinant genotype GII.b was dominant between 2003 and 2004 (83%). In conclusion, genotypes GII.4 and GIIb have emerged as predominant norovirus genotypes in endemic gastroenteritis affecting young infants and children in Finland.
Environmental characteristics associated with campylobacteriosis: accounting for the effect of age and season
Authors: ARSENAULT J. , MICHEL P. , BERKE O. , RAVEL A. , GOSSELIN P. 
Published: April 2011

SUMMARYCampylobacteriosis is a leading cause of acute bacterial gastroenteritis. An ecological study was undertaken to explore the association between environmental characteristics and incidence of campylobacteriosis in relation to four age groups and two seasonal periods. A multi-level Poisson regression model was used for modelling at the municipal level. High ruminant density was positively associated with incidence of campylobacteriosis, with a reduced effect as people become older. High poultry density and presence of a large poultry slaughterhouse were also associated with higher incidence, but only for people aged 16–34 years. The effect of ruminant density, poultry density, and slaughterhouses were constant across seasonal periods. Other associations were detected with population density and average daily precipitation. Close contacts with farm animals are probably involved in the associations observed. The specificity of age and season on this important disease must be considered in further studies and in the design of preventive measures.
The breeding biology of Chinese Crested Terns in mixed species colonies in eastern China

Published: April 2011

SummaryThe Chinese Crested Tern Thalasseus bernsteini is a Critically Endangered species and very little is known about its breeding biology and behaviour. Only two small breeding colonies have been recorded on the eastern coast of China. Between 2004 and 2009, their breeding biology was studied in two mixed species colonies on the Jiushan and Wuzhishan archipelagos in Zhejiang province. Chinese Crested Terns started breeding in late May and departed in late August, and nests were generally found within large colonies of Greater Crested Terns T. bergii. The nesting grounds of the mixed colony included grass, rock and interlaced zones on small, uninhabited islets. A total of six Chinese Crested Tern nests were identified, four of which were monitored. In these, the average clutch size was one, with an incubation period of 22–28 days and a fledging period of 31–35 days. The chicks subsequently joined chicks of the Greater Crested Tern, forming the same crèche. Adult Chinese Crested Terns foraged within approximately 5 km of the breeding islets and fed their chicks mainly with small and/or young shoaling fishes. The breeding success of Chinese Crested Tern was 100% in both 2008 and 2009. In addition to mixed nesting, other traits of breeding biology, such as breeding site shifts and re-nesting, provide valuable information for surveying, monitoring and conservation of the Chinese Crested Tern.
Processing of contrastiveness by heritage Russian bilinguals
Authors: SEKERINA IRINA A. , TRUESWELL JOHN C. 
Published: April 2011

Two eye-tracking experiments in the Visual World paradigm compared how monolingual Russian (Experiment 1) and heritage Russian–English bilingual (Experiment 2) listeners process contrastiveness online in Russian. Materials were color adjective–noun phrases embedded into the split-constituent construction Krasnuju položite zvezdočku . . . “Red put star . . .” whose inherent contrastiveness results from integration of multiple sources of information, i.e., word order, prosody and visual context. The results showed that while monolinguals rapidly used word order and visual context (but not contrastive prosody) to compute the contrast set even before the noun appeared in speech, heritage Russian bilinguals were very slow and took notice of multiple sources of information only when the lexical identity of the noun made the task superfluous. These results are similar to slowed processing reported in the literature for L2 learners. It is hypothesized that this slowdown in HL processing is due to cascading effects of covert competition between the two languages that starts at the level of spoken word recognition and culminates at the interfaces and, with time, it may become a major contributing force to heritage language attrition.
Some Secrets of Fluorescent Proteins: Distinct Bleaching in Various Mounting Fluids and Photoactivation of cyan fluorescent proteins at YFP-Excitation
Authors: Schmid Johannes , Malkani Naila 
Published: April 2011

Abstract
Background
The use of spectrally distinct variants of green fluorescent protein (GFP) such as cyan or yellow mutants (CFP and YFP, respectively) is very common in all different fields of life sciences, e.g. for marking specific proteins or cells or to determine protein interactions. In the latter case, the quantum physical phenomenon of fluorescence resonance energy transfer (FRET) is exploited by specific microscopy techniques to visualize proximity of proteins.Methodology/Principal Findings When we applied a commonly used FRET microscopy technique - the increase in donor (CFP)-fluorescence after bleaching of acceptor fluorophores (YFP), we obtained good signals in live cells, but very weak signals for the same samples after fixation and mounting in commercial microscopy mounting fluids. This observation could be traced back to much faster bleaching of CFP in these mounting media. Strikingly, the opposite effect of the mounting fluid was observed for YFP and also for other proteins such as Cerulean, TFP or Venus. The changes in photostability of CFP and YFP were not caused by the fixation but directly dependent on the mounting fluid. Furthermore we made the interesting observation that the CFP-fluorescence intensity increases by about 10 - 15% after illumination at the YFP-excitation wavelength – a phenomenon, which was also observed for Cerulean. This photoactivation of cyan fluorescent proteins at the YFP-excitation can cause false-positive signals in the FRET-microscopy technique that is based on bleaching of a yellow FRET acceptor.

Conclusions/Significance
Our results show that photostability of fluorescent proteins differs significantly for various media and that CFP bleaches significantly faster in commercial mounting fluids, while the opposite is observed for YFP and some other proteins. Moreover, we show that the FRET microscopy technique that is based on bleaching of the YFP is prone to artifacts due to photoactivation of cyan fluorescent proteins under these conditions.
In Defense of New Stoicism: Public Advocacy and Political Thought in the Age of Nero
Authors: McCormick Samuel 
Published: April 2011

ABSTRACT
Philosophers have rarely been on good terms with the city and its rulers. Among the rhetorical devices with which they have defended themselves and their discipline, few have proven more reliable than the Straussian technique of “philosophic politics.” This article calls attention to a defining moment in the history of this persuasive technique: Seneca the Younger's defense of Roman Stoicism in the mid-first century CE. In light of his public advocacy and political thought, the article concludes that an expansion of the concept of philosophic politics is in order. In addition to philosophical tracts and treatises, it should be widened to include the nonphilosophical works of their authors.
Restraint and Rhetorical Craftiness: Emphasis as a Means of Figured Speech in Montaigne's Essays
Authors: Carlos Claudia 
Published: April 2011

ABSTRACT
One of the strongest voices against rhetorical excess in the Renaissance can be found in Montaigne's Essays. It is no wonder, then, that the author's own style has often been associated with a Stoic terseness that matches a professed goal of writing sans estude et artifice—in other words, without rhetoric. But when we consider the volatile political context in which Montaigne was writing, it becomes apparent that his stylistic restraint accomplishes far more than an effect of transparency. Focusing on the figure of emphasis-one in which the rhetor allows his audience to infer an additional meaning from what he says or does not say—this article explores the connection between the restraint of Montaigne's prose style and the classical art of covert argument.
