Expansion and diversification of high-latitude radiolarian assemblages in the late Eocene linked to a cooling event in the Southwest Pacific
Authors: Pascher K. M. , Hollis C. J. , Bohaty S. M. , Cortese G. , McKay R. M.
Published: July 2015

Abstract. The Eocene was characterised by "greenhouse" climate conditions that were gradually terminated by a long-term cooling trend through the middle and late Eocene. This long-term trend was determined by several large-scale climate perturbations that culminated in a shift to "ice-house" climates at the Eocene–Oligocene Transition. Geochemical and micropaleontological proxies suggest that tropical-to-subtropical sea-surface temperatures persisted into the late Eocene in the high-latitude Southwest Pacific Ocean. Here, we present radiolarian microfossil assemblage and foraminiferal oxygen and carbon stable isotope data from Deep Sea Drilling Project (DSDP) Sites 277, 280, 281 and 283 from the middle Eocene to early Oligocene (~ 40–33 Ma) to identify oceanographic changes in the Southwest Pacific across this major transition in Earth's climate history. The Middle Eocene Climatic Optimum at ~ 40 Ma is characterised by a negative shift in foraminiferal oxygen isotope values and a radiolarian assemblage consisting of about 5 % of low latitude taxa Amphicraspedum prolixum group and Amphymenium murrayanum. In the early late Eocene at ~ 37 Ma, a positive oxygen isotope shift can be correlated to the Priabonian Oxygen Isotope Maximum (PrOM) event – a short-lived cooling event recognized throughout the Southern Ocean. Radiolarian abundance, diversity, and preservation increase during the middle of this event at Site 277 at the same time as diatoms. The PrOM and latest Eocene radiolarian assemblages are characterised by abundant high-latitude taxa. These high-latitude taxa also increase in abundance during the late Eocene and early Oligocene at DSDP Sites 280, 281 and 283 and are associated with very high diatom abundance. We therefore infer a~northward expansion of high-latitude radiolarian taxa onto the Campbell Plateau towards the end of the late Eocene. In the early Oligocene (~ 33 Ma) there is an overall decrease in radiolarian abundance and diversity at Site 277, and diatoms are absent. These data indicate that, once the Tasman Gateway was fully open in the early Oligocene, a frontal system similar to the present day was established, with nutrient-depleted subantarctic waters bathing the area around DSDP Site 277, resulting in a more oligotrophic siliceous plankton assemblage.
Impacts of storm chronology on the morphological changes of the Formby beach and dune system, UK
Authors: Dissanayake P. , Brown J. , Karunarathna H.
Published: July 2015

Abstract. Impacts of storm chronology within a storm cluster on beach/dune erosion are investigated by applying the state-of-the-art numerical model XBeach to the Sefton coast, northwest England. Six temporal storm clusters of different storm chronologies were formulated using three storms observed during the 2013/2014 winter. The storm power values of these three events nearly halve from the first to second event and from the second to third event. Cross-shore profile evolution was simulated in response to the tide, surge and wave forcing during these storms. The model was first calibrated against the available post-storm survey profiles. Cumulative impacts of beach/dune erosion during each storm cluster were simulated by using the post-storm profile of an event as the pre-storm profile for each subsequent event. For the largest event the water levels caused noticeable retreat of the dune toe due to the high water elevation. For the other events the greatest evolution occurs over the bar formations (erosion) and within the corresponding troughs (deposition) of the upper-beach profile. The sequence of events impacting the size of this ridge–runnel feature is important as it consequently changes the resilience of the system to the most extreme event that causes dune retreat. The highest erosion during each single storm event was always observed when that storm initialised the storm cluster. The most severe storm always resulted in the most erosion during each cluster, no matter when it occurred within the chronology, although the erosion volume due to this storm was reduced when it was not the primary event. The greatest cumulative cluster erosion occurred with increasing storm severity; however, the variability in cumulative cluster impact over a beach/dune cross section due to storm chronology is minimal. Initial storm impact can act to enhance or reduce the system resilience to subsequent impact, but overall the cumulative impact is controlled by the magnitude and number of the storms. This model application provides inter-survey information about morphological response to repeated storm impact. This will inform local managers of the potential beach response and dune vulnerability to variable storm configurations.

Abstract. Vineyards are one of the eco-geomorphological systems most conditioned by human activity in Germany. The vineyards of the Ruwer Valley (Germany) are characterized by high soil erosion rates and rill problems on steep slopes (between 23 and 26°) caused by the increasingly frequent heavy rainfall events as well as deterioration due to incorrect land use managements. The objective of this paper is to determine and to quantify the hydrological and erosive phenomena in one vineyard in Germany during different seasons and under different management conditions (before, during and after vintage). For this purpose, a combined methodology was applied. Climatic (rainfall depth distributions and return periods), pedological (soil analysis and classification), geomorphological (sediment movements and rills evolution) and biological (botanic marks on the vines) variables were used on the two experimental plots in the village of Waldrach (Trier, region of Rhineland-Palatinate). The results showed high infiltration rates (near 100 %) and subsurface flow which were detected by rainfall simulations performed at different times of the year (between September and December). The highest variations of the monitored rills (lateral and frontal movements) were noted before and during vintage, when footsteps occurred concentrated during a short period of time (between September and October). Finally, two maps of soil loss were generated, indicated by botanic marks on the graft union of the vines. 62.5 t ha−1 yr−1 soil loss was registered in the experimental plots of the new vineyards (2 years), while 3.4 t ha−1 yr−1 was recorded in the old one (35 years).

Published: July 2015

This research aims to cluster American and Brazilian Real Estate Investment Trusts – USAREITs and BRREITs, respectively – based on their risk-adjusted measures of performance from January/2003 to August/2013, as well as before, during and after the financial crisis of 2008. Factor and Cluster Analysis pointed out three groups. Afterwards, Kruskal-Wallis and Dwass-Steel-Chritchlow-Fligner pairwise comparisons were adopted to verify the statistical differences between clusters. Overall, BRREITs achieved a better performance before and during the crisis, but an inferior performance after the crisis. USAREITs presented a more aggressive strategy after the crisis, whilst BRREITs presented a more conservative strategy during the same period.
Political Transition in Burkina Faso: the Fall of Blaise Compaoré
Authors: Engels Bettina
Published: July 2015

This commentary traces recent regime change and political transition in Burkina Faso. After mass demonstrations Blaise Compaoré was forced to resign his presidency on 31 October 2014. His resignation was preceded by his attempt to change the constitution to allow him to stand for a fifth consecutive term in office. It is argued in this briefing that the way Compaoré’s rule ended should have come as no surprise because it was typical of both Burkina Faso’s political history since decolonisation and also the army’s historical role in the country’s presidential turnover. It was also typical of the current wave of mass protest struggles taking place in other African countries.
The management of tourism destinations
Authors: Andergassen Rainer , Candela Guido , Figini Paolo
Published: July 2015

Real-world tourism destinations differ in the way they develop and are managed. This is mainly due to the complexity of the tourism product (a bundle including both complementary and substitute goods and services) and the type of primary resource. Moreover, the planning of tourism and the policy of the destination depend on coordination and cooperation among several agents (private companies, public bodies and hybrid agents) on a plethora of issues. This article deals theoretically with the alternative patterns of strategic interaction that can be played by the different stakeholders of the destination: private agents can either play cooperative or non-cooperative pricing strategies, while the optimal investment policy for the destination management depends on the timing of the game (private and public agents’ moves can either be simultaneous or sequential). By jointly considering the two features of cooperation and game timing, the authors are able to identify four different cases for their policy model. They show that the solutions of these cases generally differ and, if private agents are coordinated, the policymaker’s choice between simultaneous and sequential moves is irrelevant. On the contrary, if agents are not coordinated, the policymaker prefers to use its first-move advantage in the sequential game in order to reduce the inefficiency stemming from the non-coordination of prices. The results are carefully discussed with respect to the peculiarity of the tourism product (where mainly complementary goods are included) and to the different patterns of destination management which are observed worldwide.

Published: July 2015

BACKGROUND: There is considerable disagreement over the effects of percutaneous coronary intervention (PCI) on left ventricular diastolic function that has necessitated the investigation of diastolic indices. The present study was conducted to evaluate left ventricular diastolic function and its indices, three months after performing the PCI procedure in patients with coronary artery disease (CAD).

METHODS: In a quasi-experimental clinical trial study (before and after), 51 patients with CAD scheduled for elective PCI were investigated provided that their Ejection Fraction (EF) was > 30%. Before and three months after PCI, echocardiography was carried out to evaluate left ventricular diastolic indices including the E/Ea as the most important criteria for diagnosis of diastolic heart failure (DHF).

RESULTS: Based on the E/Ea indices and after PCI, the number of patients with DHF decreased significantly: 40 patients (78.4%) before PCI versus 28 patients (54.9%) after PCI (p<0.05). The Mean and Standard error of deceleration time (DT), isovolumic relaxation time (IVRT), early diastolic mitral annulus velocity; Ea (E'), E/Ea and left ventricular ejection function (LVEF) indices underwent significant changes. In addition, MVA dur/PVA dur, PVs/PVd, and E/Ea indices had changed significantly after PCI in both genders. However, no significant difference was reported for the other indices.

CONCLUSION: The E/Ea ratio as an important criterion for diagnosis of DHF was improved after PCI. Improvement of several other diastolic indices was observed after the PCI procedure. It can be concluded that PCI can be an effective treatment modality in patients with left ventricular diastolic indices.
Positioning During Group Work on a Novel Task in Algebra II
Authors: DeJarnette Anna F. , González Gloriana
Published: July 2015

Given the prominence of group work in mathematics education policy and curricular materials, it is important to understand how students make sense of mathematics during group work. We applied techniques from Systemic Functional Linguistics to examine how students positioned themselves during group work on a novel task in Algebra II classes. We examined the patterns of positioning that students demonstrated during group work and how students' positioning moves related to the ways they established the resources, operations, and product of a task. Students who frequently repositioned themselves created opportunities for mathematical reasoning by attending to the resources and operations necessary for completing the task. The findings of this study suggest how students' positioning and mathematical reasoning are intertwined and jointly support collaborative learning through work on novel tasks.
The Codevelopment of Mathematical Concepts and the Practice of Defining
Authors: Kobiela Marta , Lehrer Richard
Published: July 2015

We examined the codevelopment of mathematical concepts and the mathematical practice of defining within a sixth-grade class investigating space and geometry. Drawing upon existing literature, we present a framework for describing forms of participation in defining, what we term aspects of definitional practice. Analysis of classroom interactions during 16 episodes spanning earlier and later phases of instruction illustrate how student participation in aspects of definitional practice influenced their emerging conceptions of the geometry of shape and form and how emerging conceptions of shape and form provided opportunities to develop and elaborate aspects of definitional practice. Several forms of teacher discourse appeared to support students' participation and students' increasing agency over time. These included: (a) requesting that members of the class participate in various aspects of practice, (b) asking questions that serve to expand the mathematical system, (c) modeling participation in aspects of practice, (d) proposing examples that create contest (i.e., monsters), and (e) explicitly stating expectations of and purposes for participating in the practice.

Tube Thoracostomy: A Structured Review of Case Reports and a Standardized Format for Reporting Complications
Authors: Aho Johnathon M. , Ruparel Raaj K. , Rowse Phillip G. , Brahmbhatt Rushin D. , Jenkins Donald , Rivera Mariela
Published: July 2015

Introduction

Although seemingly straightforward, tube thoracostomy (TT) has been associated with complication rates as high as 30 %. A lack of a standardized nomenclature for reporting TT complications makes comparison and evaluation of reports impossible. We aim to develop a classification method in order to standardize the reporting of complications of TT and identify all reported complications of TT and time course in which they occurred to validate the reporting method.

Methods

A systematic search of MEDLINE, Scopus, EMBASE, and Cochrane Central Register of Controlled Trials and Database of Systematic Reviews from each databases inception through November 5, 2013 was conducted. Original articles written in the English language reporting TT complications were searched. This review adhered to preferred reporting items for systematic reviews and meta‐analyses (PRISMA) standards. Duplicate reviewers abstracted case reports for inclusion. Cases were then sorted into one of the five complication categories by two reviewers, and in case of disagreements, settled by a third reviewer.

Results

Of 751 papers reporting TT complications, 124 case reports were included for analysis. From these reports, five main categories of TT complications were identified: insertional (n = 65); positional (n = 36); removal (n = 11); infective and immunologic (n = 7); and instructional, educational, or equipment related (n = 5). Placement of TT has occurred in nearly every soft tissue and vascular structure in the thoracic cavity and intra‐abdominal organs.

Conclusion

Our classification method provides further clarity and systematic standardization for reporting TT complications.
Lower Extremity Injury Patterns in Elite Ballet Dancers: Ultrasound/MRI Imaging Features and an Institutional Overview of Therapeutic Ultrasound Guided Percutaneous Interventions
Authors: Rehmani Razia , Endo Yoshimi , Bauman Phillip , Hamilton William , Potter Hollis , Adler Ronald
Published: July 2015

Background

Altered biomechanics from repetitive microtrauma, such as long practice hours in en pointe (tip of the toes) or demi pointe (balls of the feet) predispose ballet dancers to a multitude of musculoskeletal pathologies particularly in the lower extremities. Both ultrasound and magnetic resonance imaging (MRI) are radiation-sparing modalities which can be used to confidently evaluate these injuries, with ultrasound (US) offering the added utility of therapeutic intervention at the same time in experienced hands.

Questions/Purposes

The purposes of this paper were: (1) to illustrate the US and MRI features of lower extremity injury patterns in ballet dancers, focusing on pathologies commonly encountered at a single orthopedic hospital; (2) to present complementary roles of both ultrasound and MRI in the evaluation of these injuries whenever possible; (3) to review and present our institutional approach towards therapeutic ultrasound-guided interventions by presenting explicit cases.

Methods

Online searches were performed using the search criteria of “ballet biomechanics” and “ballet injuries.” The results were then further narrowed down by limiting articles published in the past 15 years, modality (US and MRI), anatomical region (foot and ankle, hip and knee) and to major radiology, orthopedics, and sports medicine journals.

Results

Performing ballet poses major stress to lower extremities and predisposes dancer to several musculoskeletal injuries. These can be adequately evaluated by both US and MRI. US is useful for evaluating superficial structures such as soft tissues, tendons, and ligaments, particularly in the foot and ankle. MRI provides superior resolution of deeper structures such as joints, bone marrow, and cartilage. In addition, US can be used as a therapeutic tool for providing quick symptomatic improvement in these athletes for who “time is money”.

Conclusion

Performing ballet may cause major stress to the lower extremities, predominantly affecting the foot and ankle, followed by the knee and hip. US and MRI play complementary roles in evaluating various orthopedic conditions in ballet dancers, with US allowing for dynamic evaluation and guidance for interventions.
Optimization of integrated scheduling of handling and storage operations at automated container terminals
Authors: Homayouni Seyed Mahdi , Tang Sai Hong
Published: July 2015

Increasing demand for containerization compels container terminals to improve their performance. Uncoordinated scheduling of operations is one of the main factors accounting for poor performance at automated container terminals (ACTs). To increase land utilization efficiency and lower operational times, a new storage system called the split-platform automated storage/retrieval system (SP-AS/RS) has been introduced for temporary storage of containers. This paper describes a multi-objective mixed-integer programming (MIP) model that is based on a combination of multiple interacting sub-tasks. It is aimed at optimizing the integrated scheduling of handling and storage operations in ACTs. The MIP model objective function is to minimize delays in the loading/unloading tasks of the cranes and the travel time of vehicles and platforms in the SP-AS/RS. At the same time, a simulated annealing algorithm (SAA) that provides near-optimal solutions for the problem in a reasonable computation time is appraised. The results of this study show that the objective function of the MIP model is, on average, 58 % lower than that of the non-integrated scheduling method. On the other hand, the best objective function values obtained by the SAA indicate only a 3.7 % disadvantage in comparison with optimal values determined by the MIP model, demonstrating that the SAA is able to provide near-optimal solutions for the integrated scheduling of handling and storage operations.

FUNERARY COMEDIES IN CONTEMPORARY KINSHASA: SOCIAL DIFFERENCE, URBAN COMMUNITIES AND THE EMERGENCE OF A CULTURAL FORM
Authors: Pype Katrien
Published: July 2015

The article situates a new type of stand-up comedy, performed in Kinshasa's mourning spaces (matanga), within the city's social universe. This type of funerary joking, enacted by comedians unrelated to the bereaved, represents a clear departure from the customary funerary humour in which accepted jokers occupy particular social positions vis-à-vis the deceased. Following recent changes in the organization of mourning rituals within the circles of Kinshasa's wealthy, these rather intimate events are ever more open to ‘strangers’, who anticipate the spending capacities of the gathered crowd. Comedians constitute one among a wide range of outsider groups who approach the bereaved community as a space of opportunity. It is argued that this emergent cultural form is utterly urban, and could only appear within urban life worlds where conviviality with others, and in particular an understanding of people's need to make a living in precarious circumstances, transforms the mourning community into an audience that pays for a cultural performance. Humour is not only derived from a symbolic difference between the poor and the rich, but also through the performance of exaggerated flattery, producing the illusion of patronage and situating the comedian within a feigned patron–client relationship for the duration of that performance.
INTRODUCTION CONTROL AND EXCESS: HISTORIES OF VIOLENCE IN AFRICA
Authors: Bernault Florence , Deutsch Jan-Georg
Published: July 2015

Violence is a murky issue to research and to theorize: this introduction suggests that it has also often been approached differently by anthropologists and historians. In the pages that follow, we reflect on the ways in which both disciplines have worked to interpret violent events in Africa, whether in the deep past, during the colonial era or in more recent periods. To better contextualize these disciplinary advances, we intersperse them with brief reviews of general theories on violence. The three articles featured in this special section, while dealing with very dissimilar case studies, provide common insights on three main themes. The first engages with the paradox of the contingency and continuity of violence, and with the unevenness of perpetrators, victims and targets. The second deals with the refractive meanings attached to violent events. The third probes, underneath the apparent turmoil of violent acts, the deep moral and cultural frameworks of action that underwrite them. We have composed this introduction around these main questions.
OBEDIENCE AND SELECTIVE GENOCIDE IN BURUNDI
Authors: Russell Aidan
Published: July 2015

Following a localized Hutu uprising in 1972, the Tutsi-dominated state in Burundi embarked on a vast series of reprisals across the country, leaving between 100,000 and 300,000 dead. Prominent political leaders were liquidated, Hutu who were able or learning to read were arrested, and many who had achieved any marginal level of exceptionality in economic success or other social achievement were accused of treason and murdered. Described as a ‘selective genocide’, the means of this violence proved deeply informative of its nature and of the experience of those caught up in the bloodshed. In the northern province of Ngozi, selection was managed through roadblocks and lists of names, creating the inescapable image of a totalitarian and bureaucratic state order. These methods fuelled a strong reaction of obedience, both among the youth and other agents of the state who took part in the arrests, and among the victims, who are commonly described as reacting with ‘docility’ to the violence. A matter of ‘law-making violence’, the selective means of the genocide shaped the political and social order that emerged from it, the ‘implements’ of genocide substantially contributing to the recognition of discrete ethnic communities among the population at large.
‘BE GRACEFUL, PATIENT, EVER PRAYERFUL’: NEGOTIATING FEMININITY, RESPECT AND THE RELIGIOUS SELF IN A NIGERIAN BEAUTY PAGEANT
Authors: Gilbert Juliet
Published: July 2015

Beauty pageants in Nigeria have become highly popular spectacles, the crowned winners venerated for their beauty, success and ability to better society through charity. This paper focuses on the Carnival Calabar Queen pageant, highlighting how pageants, at the nexus of gender and the nation, are sites of social reproduction by creating feminine ideals. A divinely inspired initiative of a fervently Pentecostal First Lady, the pageant crowns an ambassador for young women's rights. While the queen must have ‘grace and beauty’ and be ‘ever prayerful’, the discussion unravels emic conceptions of feminine beauty, religiosity and respectability. Yet, young women also use pageantry as a ‘platform’ for success, hoping to challenge the double bind of gender and generation they experience in Nigeria. The discussion pays particular attention to how young women, trying to overcome the insecurities of (urban) Nigerian life, make choices to negotiate individualism with community, and piety with patriarchy. Ethnographically, this paper situates beauty pageants in the region's past and present practices that mould feminine subjectivities. Contributing young women's experiences to recent literature on the temporalities of African youth, the paper's explicit focus on how new subjectivities form through action illuminates important themes regarding agency, resistance and notions of the religious self. In doing so, it furthers current analyses of Pentecostalism, seeking a more nuanced understanding of gender reconfiguration and demonstrating how religious subjects can be formed outside church institutions.
Development and population dynamics of Steinernema yirgalemense (Rhabditida: Steinernematidae) and growth characteristics of its associated Xenorhabdusindica symbiont in liquid culture
Authors: Ferreira T. , Addison M.F. , Malan A.P.
Published: July 2015

Entomopathogenic nematodes have become a valuable addition to the range of biological control agents available for insect control. An endemic nematode, Steinernemayirgalemense, has been found to be effective against a wide range of key insect pests. The next step would be the mass production this nematode for commercial application. This requires the establishment of monoxenic cultures of both the nematode and the symbiotic bacterium Xenorhabdus indica. First-stage juveniles of S. yirgalemense were obtained from eggs, while X. indica was isolated from nematode-infected wax moth larvae. The population density of the various life stages of S. yirgalemense during the developmental phase in liquid culture was determined. The recovery of infective juveniles (IJs) to the third-stage feeding juveniles, was 67 ± 10%, reaching a maximum population density of 75,000 IJs ml− 1 on day 13 after inoculation. Adult density increased after 8 days, with the maximum female density being 4600 ml− 1 on day 15, whereas the maximum male density was 4300 ml− 1 on day 12. Growth curves for X. indica showed that the exponential phase was reached 15 h after inoculation to the liquid medium. The stationary phase was reached after 42 h, with an average of 51 × 107 colony-forming units ml− 1. Virulence tests showed a significant difference in insect mortality between in vitro- and in vivo-produced nematodes. The success obtained with the production of S. yirgalemense in liquid culture can serve as the first step in the optimizing and upscaling of the commercial production of nematodes in fermenters.
Jentink's duiker in Sierra Leone: evidence from the Freetown Peninsula
Authors: Davies Glyn , Birkenhäger Bastian
Published: July 2015

Jentink's duiker, Africa's rarest duiker, was reported to be common in Sierra Leone at the turn of the century, but subsequent investigations failed to find evidence of the animal's presence. In 1988, as part of a faunal survey organized by the Conservation Society of Sierra Leone, the authors discovered that the duiker definitely occurred there and that some had been recently killed. Although this finding extends the known range of the species, the duiker is rare and remains poorly known. There were recommendations to protect the forests of the Freetown Peninsula even before the presence of the duiker was confirmed and these are now reinforced.
Javan rhinoceros in Vietnam

Published: July 2015

Two species of rhinoceros—the Javan and the Sumatran—once inhabited Vietnam but the Sumatran rhinoceros apparently became extinct there early this century and by the late 1960s it was feared that the Javan rhinoceros probably no longer occurred there either. Then, in November 1988, a hunter shot an adult female rhinoceros about 130 km north-east of Saigon. He was arrested when he tried to sell the horn and hide. In early 1989 the authors were conducting wildlife surveys near where the killing took place and they took this opportunity to check the status of the species. They found evidence that perhaps 10–15 Javan rhinoceros still survive in Vietnam. As a result of this discovery the Vietnamese Government has set up a Rhinoceros Conservation Group.
Conserving Pacific Island flying foxes
Authors: Bräutigam Amie , Elmqvist Thomas
Published: July 2015

Pacific Islanders, conservationists, and bat biologists are applauding the recent decision of the Parties to the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) to increase protection of flying foxes, or fruit bats, of the genera Acerodon and Pteropus from the adverse effects of international trade into US jurisdictions in the Pacific. This decision culminates efforts dating as far back as 1981 to control international trade in these species, which has decimated populations on many islands. It poses a challenge to US government authorities to institute wildlife trade controls in the Pacific and to Pacific Island governments, many of which are not yet CITES members, to develop effective measures to control exports of these and other species.

A Swedish national twin study of criminal behavior and its violent, white-collar and property subtypes
Authors: Kendler K. S. , Maes H. H. , Lönn S. L. , Morris N. A. , Lichtenstein P. , Sundquist J. , Sundquist K.
Published: July 2015

Background

We sought to clarify the etiological contribution of genetic and environmental factors to total criminal behavior (CB) measured as criminal convictions in men and women, and to violent (VCB), white-collar (WCCB) and property criminal behavior (PCB) in men only.

Method

In 21 603 twin pairs from the Swedish Twin Registry, we obtained information on all criminal convictions from 1973 to 2011 from the Swedish Crime Register. Twin modeling was performed using the OpenMx package.

Results

For all criminal convictions, heritability was estimated at around 45% in both sexes, with the shared environment accounting for 18% of the variance in liability in females and 27% in males. The correlation of these risk factors across sexes was estimated at +0.63. In men, the magnitudes of genetic and environmental influence were similar in the three criminal conviction subtypes. However, for violent and white-collar convictions, nearly half and one-third of the genetic effects were respectively unique to that criminal subtype. About half of the familial environmental effects were unique to property convictions.

Conclusions

The familial aggregation of officially recorded CB is substantial and results from both genetic and familial environmental factors. These factors are moderately correlated across the sexes suggesting that some genetic and environmental influences on criminal convictions are unique to men and to women. Violent criminal behavior and property crime are substantially influenced respectively by genetic and shared environmental risk factors unique to that criminal subtype.
Visual memory and sustained attention impairment in youths with autism spectrum disorders
Authors: Chien Y.-L. , Gau S. S.-F. , Shang C.-Y. , Chiu Y.-N. , Tsai W.-C. , Wu Y.-Y
Published: July 2015

Background

An uneven neurocognitive profile is a hallmark of autism spectrum disorder (ASD). Studies focusing on the visual memory performance in ASD have shown controversial results. We investigated visual memory and sustained attention in youths with ASD and typically developing (TD) youths.

Method

We recruited 143 pairs of youths with ASD (males 93.7%; mean age 13.1, s.d. 3.5 years) and age- and sex-matched TD youths. The ASD group consisted of 67 youths with autistic disorder (autism) and 76 with Asperger's disorder (AS) based on the DSM-IV criteria. They were assessed using the Cambridge Neuropsychological Test Automated Battery involving the visual memory [spatial recognition memory (SRM), delayed matching to sample (DMS), paired associates learning (PAL)] and sustained attention (rapid visual information processing; RVP).

Results

Youths with ASD performed significantly worse than TD youths on most of the tasks; the significance disappeared in the superior intelligence quotient (IQ) subgroup. The response latency on the tasks did not differ between the ASD and TD groups. Age had significant main effects on SRM, DMS, RVP and part of PAL tasks and had an interaction with diagnosis in DMS and RVP performance. There was no significant difference between autism and AS on visual tasks.

Conclusions

Our findings implied that youths with ASD had a wide range of visual memory and sustained attention impairment that was moderated by age and IQ, which supports temporal and frontal lobe dysfunction in ASD. The lack of difference between autism and AS implies that visual memory and sustained attention cannot distinguish these two ASD subtypes, which supports DSM-5 ASD criteria.
Towards a genealogy of ‘society’ in International Relations
Authors: BARTELSON JENS
Published: July 2015

The concept of society and its cognates have long been widely invoked in order to understand International Relations. Theories of international society distinguish between a society of states and a mere system of states, and theories of world society assume that the world constitutes a single social space. In order to come to terms with the social character of International Relations, constructivists of different stripes have invoked a societal context within which the construction of identities and norms takes place. As I shall argue in this article, these usages draw on conceptions of society that emerged during the early phases of modern sociology, and have then been projected onto alien historical and cultural contexts. In order to avoid the anachronism and Eurocentrism that invariably have resulted from these uncritical usages, I argue that academic International Relations should seek to accommodate those forms of human association that cannot be subsumed under a recognisably modern concept of society by incorporating insights from postcolonial sociology into its theoretical core.
Uniformity of fuel target implosion in heavy ion fusion
Authors: Kawata S. , Noguchi K. , Suzuki T. , Karino T. , Barada D. , Ogoyski A.I. , Ma Y.Y.
Published: July 2015

In inertial confinement fusion the target implosion non-uniformity is introduced by a driver beams’ illumination non-uniformity, a fuel target alignment error in a fusion reactor, the target fabrication defect, etc. For a steady operation of a fusion power plant the target implosion should be robust against the implosion non-uniformities. In this paper the requirement for the implosion uniformity is first discussed. The implosion uniformity should be less than a few percent. A study on the fuel hotspot dynamics is also presented and shows that the stagnating plasma fluid provides a significant enhancement of vorticity at the final stage of the fuel stagnation. Then non-uniformity mitigation mechanisms of the heavy-ion beam (HIB) illumination are also briefly discussed in heavy ion inertial fusion (HIF). A density valley appears in the energy absorber, and the large-scale density valley also works as a radiation energy confinement layer, which contributes to a radiation energy smoothing. In HIF a wobbling HIB illumination was also introduced to realize a uniform implosion. In the wobbling HIBs illumination, the illumination non-uniformity oscillates in time and space on a HIF target. The oscillating-HIB energy deposition may contribute to the reduction of the HIBs’ illumination non-uniformity by its smoothing effect on the HIB illumination non-uniformity and also by a growth mitigation effect on the Rayleigh–Taylor instability.
Characteristics of target polarization by laser ablation

Experimental results are obtained concerning the target polarization, which aptly characterizes the laser ablation. The charge separation in the laser-produced plasma, structure of the ion front, and the current of fast electrons expanding into the vacuum chamber ahead of ions are of crucial importance for the interpretation of multi-peak structure of target currents appearing much later than the laser pulse. Of particular interest is the correlation between the partial maxima in the time-resolved target current and the square root of mass number of ionized species. The late-time negative charging of targets provides evidence for production of very slow ions by ionization of neutrals ablated at the target crater by radiation from plasma produced by 23 ns excimer krypton fluoride laser.
Inter- and Extra-textual Hauntings: Unravelling the Semantic Web of Václav Havel’s Leaving
Authors: Fry Katie
Published: July 2015

Leaving (2007), the first play written by Václav Havel since the start of his political career in 1989, is a theatrical tour de force that categorically defies generic classification. In this article Katie Fry draws on methodologies of theatre semiotics and intertextuality to elucidate the semantic complexity of Havel’s highly unconventional play. Leaving is analyzed in terms of its engagement with intertexts, its incorporation of ‘real-life’ material from Havel’s political and artistic careers, and its subversion of theatrical conventions. Katie Fry is a PhD Candidate at the Centre for Comparative Literature, University of Toronto. She has worked as a translator and dramaturg for independent theatre projects in Madrid and Toronto. Her dissertation project examines the attribution of religious import to theatre, opera, and literature in nineteenth- and early twentieth-century Europe. She holds a doctoral fellowship from the Social Sciences and Humanities Research Council of Canada.
Alive, Kicking – and Kicking Back: Russia’s Golden Mask Festival 2015
Authors: Shevtsova Maria
Published: July 2015

The Golden Mask and National Theatre Award and Festival, founded in Moscow in 1994, has showcased some of the most exciting theatre to be found across Russia’s vast territories: ‘theatre’ including opera, ballet, contemporary dance, puppetry, and newer forms that have taken root with changing artistic practices. Maria Shevtsova’s brief overview of the 2015 Russian Case, a selection for foreign producers and critics, prominently features ‘new drama’, not least because of the difficulties recently imposed on Teatr.doc, a founding player within this powerful movement. Major young directors appear here, with crossover to their work as represented in past editions of the Russian Case, and with reference to current socio-political factors. Reviews of earlier festivals appeared in NTQ 85, 95, and 103. Maria Shevtsova, Professor at Goldsmiths, University of London, is co-editor of New Theatre Quarterly. Her most recent book is the co-authored Cambridge Introduction to Theatre Directing (2013). Her seminal Dodin and the Maly Drama Theatre: Process to Performance (2004) has been translated into Romanian, Korean, and Mandarin and, in 2014, Russian.
COUNTABLE STATE MARKOV PROCESSES: NON-EXPLOSIVENESS AND MOMENT FUNCTION
Authors: Spieksma F.M.
Published: July 2015

The existence of a moment function satisfying a drift function condition is well known to guarantee non-explosiveness of the associated minimal Markov process (cf. [1,9]), under standard technical conditions. Surprisingly, the reverse is true as well for a countable space Markov process. We prove this result by showing that recurrence of an associated jump process, that we call the α-jump process, is equivalent to non-explosiveness. Non-explosiveness corresponds in a natural way to the validity of the Kolmogorov integral relation for the function identically equal to 1. In particular, we show that positive recurrence of the α-jump chain implies that all bounded functions satisfy the Kolmogorov integral relation. We present a drift function criterion characterizing positive recurrence of this α-jump chain.

Suppose that to a drift functionVthere corresponds another drift functionW, which is a moment with respect toV. Via a transformation argument, the above relations hold for the transformed process with respect toV. Transferring the results back to the original process, allows to characterize theV-bounded functions that satisfy the Kolmogorov forward equation.

At the crossroad between nutrient supply and requirements, the liver plays a central role in partitioning nitrogenous nutrients among tissues. The present review examines the utilisation of amino acids (AA) within the liver in various physiopathological states in mammals and how the fates of AA are regulated. AA uptake by the liver is generally driven by the net portal appearance of AA. This coordination is lost when demands by peripheral tissues is important (rapid growth or lactation), or when certain metabolic pathways within the liver become a priority (synthesis of acute-phase proteins). Data obtained in various species have shown that oxidation of AA and export protein synthesis usually responds to nutrient supply. Gluconeogenesis from AA is less dependent on hepatic delivery and the nature of nutrients supplied, and hormones like insulin are involved in the regulatory processes. Gluconeogenesis is regulated by nutritional factors very differently between mammals (glucose absorbed from the diet is important in single-stomached animals, while in carnivores, glucose from endogenous origin is key). The underlying mechanisms explaining how the liver adapts its AA utilisation to the body requirements are complex. The highly adaptable hepatic metabolism must be capable to deal with the various nutritional/physiological challenges that mammals have to face to maintain homeostasis. Whereas the liver responds generally to nutritional parameters in various physiological states occurring throughout life, other complex signalling pathways at systemic and tissue level (hormones, cytokines, nutrients, etc.) are involved additionally in specific physiological/nutritional states to prioritise certain metabolic pathways (pathological states or when nutritional requirements are uncovered).
All of London's a stage: the 1943 County of London Plan Exhibition
Authors: AMATI MARCO , FREESTONE ROBERT
Published: July 2015

The post-war reconstruction era was marked by numerous planning exhibitions which provide a window on the contemporary nature of communication and consultation in planning practice. The 1943 Exhibition of the County of London Plan prepared by J.H. Forshaw and Patrick Abercrombie was a major event with the king and queen making a high-profile visit. This article describes the making of the exhibition, considers its content, design and historical significance and reflects on its importance as a high water mark in the culture of twentieth-century town planning promotion generally and exhibition culture specifically. Archival research reveals how the London County Council (LCC) negotiated for resources from the central government and the local boroughs in hosting and organizing the event and how crucial these negotiations were in its eventual staging, marketing and impact.
Influence of personal choices on lexical variability in referring expressions

Published: July 2015

Variability is inherent in human language as different people make different choices when facing the same communicative act. In Natural Language Processing, variability is a challenge. It hinders some tasks such as evaluation of generated expressions, while it constitutes an interesting resource to achieve naturalness and to avoid repetitiveness. In this work, we present a methodological approach to study the influence of lexical variability. We apply this approach to TUNA, a corpus of referring expression lexicalizations, in order to study the use of different lexical choices. First, we reannotate the TUNA corpus with new information about lexicalization, and then we analyze this reannotation to study how people lexicalize referring expressions. The results show that people tend to be consistent when generating referring expressions. But at the same time, different people also share certain preferences.

Published: July 2015

Understanding the morphological structure of membranes is essential to improve performance of membrane-based applications. In this paper, macroporous membranes were investigated and two methods introduced as an alternative for characterization of stereo-structure of the membranes. We combined the use of synchrotron X-ray nanotomography and small-angle X-ray scattering to examine the internal structure of cellulose acetate membranes with studies of the capture of surface-modified gold nanoparticles within these membranes. Finally, the morphological structures of macroporous membranes were visualized and their relationships with penetration tendency of surface-modified gold nanoparticles were explained.
