COLLABORATIVE RESEARCH, DELIBERATION, AND INNOVATION
Authors: Wray K. Brad
Published: April 2014

I evaluate the extent to which we could learn something about how we should be conducting collaborative research in science from the research on groupthink. I argue that Solomon has set us in the wrong direction, failing to recognize that the consensus in scientific specialties is not the result of deliberation. But the attention to the structure of problem-solving that has emerged in the groupthink research conducted by psychologists can help us see when deliberation could lead to problems for a research team. I argue that whenever we need to generate alternative solutions or proposals, groupthink is a genuine threat, and research teams would be wise to allow individuals opportunities to work alone. But the benefits of team work emerge when scientists seek to evaluate the various proposals generated, and determine a course of action. Then the group is less prone is groupthink, and the interaction of group members can be an epistemic asset.
Dynamical properties of spatial discretizations of a generic homeomorphism
Authors: GUIHÉNEUF PIERRE-ANTOINE
Published: April 2014

This paper concerns the link between the dynamical behaviour of a dynamical system and the dynamical behaviour of its numerical simulations. Here, we model numerical truncation as a spatial discretization of the system. Some previous works on well-chosen examples (such as Gambaudo and Tresser [Some difficulties generated by small sinks in the numerical study of dynamical systems: two examples. Phys. Lett. A 94(9) (1983), 412–414]) show that the dynamical behaviours of dynamical systems and of their discretizations can be quite different. We are interested in generic homeomorphisms of compact manifolds. So our aim is to tackle the following question: can the dynamical properties of a generic homeomorphism be detected on the spatial discretizations of this homeomorphism? We will prove that the dynamics of a single discretization of a generic conservative homeomorphism does not depend on the homeomorphism itself, but rather on the grid used for the discretization. Therefore, dynamical properties of a given generic conservative homeomorphism cannot be detected using a single discretization. Nevertheless, we will also prove that some dynamical features of a generic conservative homeomorphism (such as the set of the periods of all periodic points) can be read on a sequence of finer and finer discretizations.
Good Kings, Bloody Tyrants, and Everything In Between: Representations of the Monarchy in Post-Genocide Rwanda
Authors: Jessee Erin , Watkins Sarah E.
Published: April 2014

Since assuming power after the 1994 genocide, President Paul Kagame and his political party, the Rwandan Patriotic Front, have struggled to unite Rwanda’s citizens using, among other initiatives, a simplified version of Rwandan history to diminish the ethnic tensions that made the 1994 genocide possible. As a result, Rwanda’s history has become highly politicized, with vastly divergent versions of the nation’s past narrated in private settings, where it is more politically appropriate for Rwandans to share their experiences. This paper focuses on divergent representations of Rwandan monarchical figures – often unnamed – whom the narrators imbue with values according to their individual political affiliations, lived experiences, and identity. These narratives are indicative of the broader ways that modern Rwandans narrate their experiences of history in response to Rwanda’s current official history, as well as previous official histories. Careful analysis reveals much about the current political climate in post-genocide Rwanda: most notably, that Rwandans continue to see their nation’s past through vastly different lenses, demonstrating the enormous challenges facing the Rwandan government as it seeks to reconcile its population using current methods. It also highlights the ongoing need on the part of historians to approach contemporary sources critically, informed by sources produced and debated in the pre-genocide period.
Irradiation uniformity at the Laser MegaJoule facility in the context of the shock ignition scheme
Authors: Temporal Mauro , Canaud Benoit , Garbett Warren J. , Ramis Rafael , Weber Stefan
Published: April 2014

The use of the Laser MegaJoule facility within the shock ignition scheme has been considered. In the first part of the study, one-dimensional hydrodynamic calculations were performed for an inertial confinement fusion capsule in the context of the shock ignition scheme providing the energy gain and an estimation of the increase of the peak power due to the reduction of the photon penetration expected during the high-intensity spike pulse. In the second part, we considered a Laser MegaJoule configuration consisting of 176 laser beams that have been grouped providing two different irradiation schemes. In this configuration the maximum available energy and power are 1.3 MJ and 440 TW. Optimization of the laser–capsule parameters that minimize the irradiation non-uniformity during the first few ns of the foot pulse has been performed. The calculations take into account the specific elliptical laser intensity profile provided at the Laser MegaJoule and the expected beam uncertainties. A significant improvement of the illumination uniformity provided by the polar direct drive technique has been demonstrated. Three-dimensional hydrodynamic calculations have been performed in order to analyse the magnitude of the azimuthal component of the irradiation that is neglected in two-dimensional hydrodynamic simulations.
Experimental investigation of aerofoil tonal noise generation
Authors: Pröbsting S. , Serpieri J. , Scarano F.
Published: April 2014

The present study investigates the mechanisms associated with tonal noise emission from a NACA 0012 aerofoil at moderate incidence ($0^{\circ },1^{\circ },2^{\circ }$ and $4^{\circ }$ angle of attack) and with Reynolds numbers ranging from 100 000 to 270 000. Simultaneous time-resolved particle image velocimetry (PIV) of the aeroacoustic source region near the trailing edge and acoustic measurements in the far field are performed in order to establish the correspondence between the flow structure and acoustic emissions. Results of these experiments are presented and analysed in view of past research for a number of selected cases. Characteristics of the acoustic emission and principal features of the average flow field agree with data presented in previous studies on the topic. Time-resolved analysis shows that downstream convecting vortical structures, resulting from growing shear layer instabilities, coherently pass the trailing edge at a frequency equal to that of the dominant tone. Therefore, the scattering of the vortical structures and their associated wall pressure fluctuations are identified as tone generating mechanisms for the cases investigated here. Moreover, wavelet analysis of the acoustic pressure and velocity signals near the trailing edge show a similar periodic amplitude modulation which is associated with multiple tonal peaks in the acoustic spectrum. Periodic amplitude modulation of the acoustic pressure and velocity fluctuations on the pressure side are also observed when transition is forced on the suction side, showing that pressure-side events alone can be the cause.
Fluid–structure interaction of a square cylinder at different angles of attack
Authors: Zhao Jisheng , Leontini Justin S. , Lo Jacono David , Sheridan John
Published: April 2014

This study investigates the free transverse flow-induced vibration (FIV) of an elastically mounted low-mass-ratio square cylinder in a free stream, at three different incidence angles: ${{\alpha }}=0^\circ $, $20^\circ $ and $45^\circ $. This geometric setup presents a body with an angle of attack, sharp corners and some afterbody, and therefore is a generic body that can be used to investigate a wide range of FIV phenomena. A recent study by Nemes et al. (J. Fluid Mech., vol. 710, 2012, pp. 102–130) provided a broad overview of the flow regimes present as a function of both the angle of attack ${{\alpha }}$ and reduced flow velocity ${U^{*}}$. Here, the focus is on the three aforementioned representative angles of attack: ${{\alpha }}=0^\circ $, where the FIV is dominated by transverse galloping; ${{\alpha }}=45^\circ $, where the FIV is dominated by vortex-induced vibration (VIV); and an intermediate value of ${{\alpha }}=20^\circ $, where the underlying FIV phenomenon has previously been difficult to determine. For the ${{\alpha }}=0^\circ $ case, the amplitude of oscillation increases linearly with the flow speed except for a series of regimes that occur when the vortex shedding frequency is in the vicinity of an odd-integer multiple of the galloping oscillation frequency, and the vortex shedding synchronizes to this multiple of the oscillation frequency. It is shown that only odd-integer multiple synchronizations should occur. These synchronizations explain the ‘kinks’ in the galloping amplitude response for light bodies first observed by Bearman et al. (J. Fluids Struct., vol. 1, 1987, pp. 19–34). For the ${{\alpha }}=45^\circ $ case, the VIV response consists of a number of subtle, but distinctly different regimes, with five regimes of high-amplitude oscillations, compared to two found in the classic VIV studies of a circular cylinder. For the intermediate ${{\alpha }}=20^\circ $ case, a typical VIV ‘upper branch’ occurs followed by a ‘higher branch’ of very large-amplitude response. The higher branch is caused by a subharmonic synchronization between the vortex shedding and the body oscillation frequency, where two cycles of vortex shedding occur over one cycle of oscillation. It appears that this subharmonic synchronization is a direct result of the asymmetric body. Overall, the FIV of the square cylinder is shown to be very rich, with a number of distinct regimes, controlled by both ${{\alpha }}$ and ${U^{*}}$. Importantly, ${{\alpha }}$ controls the underlying FIV phenomenon, as well as controlling the types of possible synchronization between the oscillation and vortex shedding.
THE WATER RELATIONS AND IRRIGATION REQUIREMENTS OF LYCHEE (LITCHI CHINENSIS SONN.): A REVIEW
Authors: CARR M. K. V. , MENZEL C. M.
Published: April 2014

The results of research into the water relations and irrigation requirements of lychee are collated and reviewed. The stages of plant development are summarised, with an emphasis on factors influencing the flowering process. This is followed by reviews of plant water relations, water requirements, water productivity and, finally, irrigation systems. The lychee tree is native to the rainforests of southern China and northern Vietnam, and the main centres of production remain close to this area. In contrast, much of the research on the water relations of this crop has been conducted in South Africa, Australia and Israel where the tree is relatively new. Vegetative growth occurs in a series of flushes. Terminal inflorescences are borne on current shoot growth under cool (<15 °C), dry conditions. Trees generally do not produce fruit in the tropics at altitudes below 300 m. Poor and erratic flowering results in low and irregular fruit yields. Drought can enhance flowering in locations with dry winters. Roots can extract water from depths greater than 2 m. Diurnal trends in stomatal conductance closely match those of leaf water status. Both variables mirror changes in the saturation deficit of the air. Very little research on crop water requirements has been reported. Crop responses to irrigation are complex. In areas with low rainfall after harvest, a moderate water deficit before floral initiation can increase flowering and yield. In contrast, fruit set and yield can be reduced by a severe water deficit after flowering, and the risk of fruit splitting increased. Water productivity has not been quantified. Supplementary irrigation in South-east Asia is limited by topography and competition for water from the summer rice crop, but irrigation is practised in Israel, South Africa, Australia and some other places. Research is needed to determine the benefits of irrigation in different growing areas.
Irrigation, Commercialization, and Social Change in Nineteenth-Century Inner Mongolia
Authors: Wang Yi
Published: April 2014

This article examines the rise of an irrigation economy in Hetao along the Yellow River during the nineteenth century, and uses it as a case study to illustrate how the periphery played a major and hitherto overlooked role in the development of the Chinese economy, which confounds the conventional view of a Chinese path of development that replicated smallholder farming. I focus on a group of Han entrepreneurs known as land merchants (dishang) who combined capital and expertise in irrigation development, and introduced a new set of property regime and socio-technical arrangements that fundamentally changed the frontier society. By linking the changes in local society to regional and global processes, this study demonstrates the centrality of the periphery as not only a zone of possibility and experimentation, but more importantly, a “contact zone” that facilitated China's integration into a new global market system.
Initial experience of a rapid-insertion bone-anchored hearing system: series of 20 consecutive implants
Authors: Muzaffar S J , Coulson C J , Burrell S , Reid A P
Published: April 2014

Objective:

The loading of bone-anchored hearing system sound processors usually occurs two to three months after surgical implant. This study examined a new bone-anchored hearing system coupling mechanism that permits loading at two weeks post-implantation without compromising osseointegration.

Methods:

Twenty implants were implanted into 15 patients. The interval between operation and time of processor loading was recorded, along with the cause of any delay and any late complications.

Results:

Two patients were fitted with implants at seven and nine weeks. The delay was a result of administrative errors; the patients reported no skin problems. Of the remaining 17 implants, 8 processors were fitted at 2 weeks, 1 at 3 weeks, 4 at 4 weeks, 3 at 7 weeks and 1 at 8 weeks. For those nine implants fitted later than two weeks, the delay was because of incomplete skin healing.

Conclusion:

The Oticon Medical Xpress system allowed processor loading at two weeks post-operatively, providing skin healing was adequate. Early loading occurred in approximately half of the patients. All patients were fitted within the two to three months traditionally allowed. Prolonged skin healing time was the main reason for the delayed fitting of sound processors.
Women of ‘Ill Repute’: Ethics and Urdu literature in colonial India
Authors: WAHEED SARAH
Published: April 2014

The courtesan, the embodiment of both threat and allure, was a central figure in the moral discourses of the Muslim ‘respectable’ classes of colonial North India. Since women are seen as the bearers of culture, tradition, the honour of the family, community, and nation, control over women's sexuality becomes a central feature in the process of forming identity and community. As a public woman, the courtesan became the target of severe moral regulation from the mid-nineteenth century onwards. The way in which the courtesan was invoked within aesthetic, ethical, and legal domains shifted over time, and by the third decade of the twentieth century, there appeared a new way of speaking and writing about the ‘fallen woman’ within the Urdu public sphere. A social critique emerged which heralded the prostitute-courtesan as an ethical figure struggling against an unjust social order. Since the courtesan symbolized both elite Mughal court culture as well as its decay, she was a convenient foil for some nationalists to challenge the dominant idioms of nationalist and communitarian politics. Moreover, certain late medieval and early modern Indo-Persian ethical concepts were redeployed by twentieth century writers for ‘progressive’ ends. This illustrated a turn to progressive cultural politics that was simultaneously anti-colonial and anti-communitarian, while maintaining a critical posture towards the dominant idioms of Indian nationalism.

Published: April 2014

Cette étude a examiné les expériences informelles des aidants familiaux en soutenant les transitions de soins entre l’hôpital et la maison pour les adultes âgés avec des conditions médicales complexes. En utilisant une approche basée sur la théorie ancrée qualitative, une série d’entretiens semi-structurés a été realisée avec la communauté et des gestionnaires de cas et de ressources, ainsi qu’avec des aidants naturels de patients âgés souffrant de fractures de la hanche et des accidents vasculaires cérébraux et ceux qui se remettaient d’une chirurgie pour remplacement de la hanche. Six propriétés qui caractérisent les besoins des aidants naturels de fournir des soins de transition entre l’hôpital et la maison avec succès ont été intégrées dans une théorie qui adressent (1) l’horaire des soins transitoires et (2) le passage émotionnel. Ces six propriétés comprennent : (1) l’évaluation des situations familiales; (2) des informations sur les pratiques; (3) l’éducation et la formation; (4) l’accord entre les aidants officiels et informels; (5) le temps de prendre des dispositions pour la vie personnelle, et (6) la préparation affective et émotionelle. Cette étude soutiendra le développement d’interventions mieux informées et plus pertinentes, qui offrent le soutien le plus approprié pour les patients et leurs familles pendant les soins de transition.
Pondering Dysfunctions in Heritage Protection: Lessons from the Theft of theCodex Calixtinus
Authors: Vargas Michael A.
Published: April 2014

TheCodex Calixtinus, the 12th-century manuscript at the heart of Spain’s Camino de Santiago, was stolen, hidden for a year, and then found in a trash can wrapped in newsprint and plastic. The extraordinary theft highlights some dysfunctions in cultural heritage thought and practice. Explored here are questions about exemplars and copies, ambiguities in heritage protection law, problems of proprietorship and commercialization of heritage goods, and administrative negligence in the management of heritage assets. The focus is on Spain, but the questions have broad relevance. This article concludes that one way to better protect movable heritage assets like the codex is to recognize them as part of a broad heritage landscape in which their loss or mismanagement means damage to an entire ecosystem of culture and history.
Managing Urban Archaeological Heritage: Latin American Case Studies
Authors: Castillo Alicia , Menéndez Sonia
Published: April 2014

This article focuses on the idea that archaeology aids the revaluation of cultural properties within historical centers. At the same time, it holds that the application of the Convention Concerning the Protection of the World Cultural and Natural Heritage of 1972 should imply the development of best management practices at inscribed sites. The handling of archaeological heritage in three Latin American cities is presented and discussed in this study, through the theoretical assumptions of preventive archaeology for the management of archaeological properties. It examines the different social contexts of World Heritage in these areas and concludes that the traditional vision of World Heritage impedes other historical readings of the past in these places. This conclusion is reached through a proactive vision defending the use of these UNESCO World Heritage Sites to improve management models with high public participation, the use of which should also be considered in the European community. There is, finally, a reminder of the desired objective: the improvement of archaeological management and, consequently, of urban historical discourses, whose outcomes enrich the lives of citizens.
Quantifying differences in the epidemic curves from three influenza surveillance systems: a nonlinear regression analysis
Authors: THOMAS E. G. , McCAW J. M. , KELLY H. A. , GRANT K. A. , McVERNON J.
Published: April 2014

Influenza surveillance enables systematic collection of data on spatially and demographically heterogeneous epidemics. Different data collection mechanisms record different aspects of the underlying epidemic with varying bias and noise. We aimed to characterize key differences in weekly incidence data from three influenza surveillance systems in Melbourne, Australia, from 2009 to 2012: laboratory-confirmed influenza notified to the Victorian Department of Health, influenza-like illness (ILI) reported through the Victorian General Practice Sentinel Surveillance scheme, and ILI cases presenting to the Melbourne Medical Deputising Service. Using nonlinear regression, we found that after adjusting for the effects of geographical region and age group, characteristics of the epidemic curve (including season length, timing of peak incidence and constant baseline activity) varied across the systems. We conclude that unmeasured factors endogenous to each surveillance system cause differences in the disease patterns recorded. Future research, particularly data synthesis studies, could benefit from accounting for these differences.

Published: April 2014

A retrospective cohort study was conducted to identify risk factors for bovine tuberculosis (bTB) recurrence in New Zealand cattle and deer herds identified as bTB-infected from 1 June 2006 to 1 November 2010. A Cox proportional hazards model identified a positive relationship between the daily hazard of bTB recurrence and: (1) the number of prior bTB episodes for two episodes [hazard ratio (HR) 3·22, 95% confidence interval (CI) 1·21–8·60], and for five episodes (HR 89·5, 95% CI 13·8–580), (2) more than one positive bTB case animal at the index episode (HR 2·25, 95% CI 1·19–4·25) and (3) the presence of cleared test-positives at the final test of the index episode. The proportional hazards assumption was violated for the latter variable so a time-dependent covariate was introduced. Up to 2 years post-clearance, the daily hazard of bTB recurrence was greater in herds with test-positives at the final test (HR 2·59, 95% CI 1·30–5·13), but this effect was not observed more than 2 years' post-clearance (HR 1·05, 95% CI 0·28–3·91). We conclude that unresolved infection contributes to further bTB episodes in the first 2 years after herd clearance.
Appropriateness of administrative data for vaccine impact evaluation: the case of pneumonia hospitalizations and pneumococcal vaccine in Brazil

Published: April 2014

Ten-valent pneumococcal conjugate vaccine (PCV10) was recently introduced into the Brazilian Immunization Programme. Secondary data are used as a measurement of community-acquired pneumonia (CAP) burden, but their completeness and reliability need to be ascertained. We performed probabilistic linkage between hospital primary data from active prospective population-based surveillance (APS) and hospital secondary data from the Hospital Information System administrative database of the National Unified Health System (SIH-SUS). Children aged 2–23 months hospitalized during January–December 2012 were identified. Incidence rates of hospitalized CAP were estimated. Agreement of case identification was measured by kappa index. A total of 1639 (26%) CAP cases were identified in APS and 1714 (35%) in SIH-SUS. Of these 3353 records, 1127 CAP cases were present in both databases. Kappa on CAP case identification was 0·72 (95% confidence interval 0·69–0·75). CAP hospitalization incidence using administrative (5285/100 000) and hospital (5054/100 000) primary data were similar (P = 0·184). Our findings suggest that administrative databases of hospitalizations are reliable sources to assess PCV10 impact in time-series analyses.
Short-wavelength cone-opponent retinal ganglion cells in mammals
Authors: MARSHAK DAVID W. , MILLS STEPHEN L.
Published: April 2014

In all of the mammalian species studied to date, the short-wavelength-sensitive (S) cones and the S-cone bipolar cells that receive their input are very similar, but the retinal ganglion cells that receive synapses from the S-cone bipolar cells appear to be quite different. Here, we review the literature on mammalian retinal ganglion cells that respond selectively to stimulation of S-cones and respond with opposite polarity to longer wavelength stimuli. There are at least three basic mechanisms to generate these color-opponent responses, including: (1) opponency is generated in the outer plexiform layer by horizontal cells and is conveyed to the ganglion cellsviaS-cone bipolar cells, (2) inputs from bipolar cells with different cone inputs and opposite response polarity converge directly on the ganglion cells, and (3) inputs from S-cone bipolar cells are inverted by S-cone amacrine cells. These are not mutually exclusive; some mammalian ganglion cells that respond selectively to S-cone stimulation seem to utilize at least two of them. Based on these findings, we suggest that the small bistratified ganglion cells described in primates are not the ancestral type, as proposed previously. Instead, the known types of ganglion cells in this pathway evolved from monostratified ancestral types and became bistratified in some mammalian lineages.
S-cone psychophysics
Authors: SMITHSON HANNAH E.
Published: April 2014

We review the features of the S-cone system that appeal to the psychophysicist and summarize the celebrated characteristics of S-cone mediated vision. Two factors are emphasized: First, the fine stimulus control that is required to isolate putative visual mechanisms and second, the relationship between physiological data and psychophysical approaches. We review convergent findings from physiology and psychophysics with respect to asymmetries in the retinal wiring of S-ON and S-OFF visual pathways, and the associated treatment of increments and decrements in the S-cone system. Beyond the retina, we consider the lack of S-cone projections to superior colliculus and the use of S-cone stimuli in experimental psychology, for example to address questions about the mechanisms of visually driven attention. Careful selection of stimulus parameters enables psychophysicists to produce entirely reversible, temporary, “lesions,” and to assess behavior in the absence of specific neural subsystems.

In this paper we prove that two local conditions involving the degrees and co-degrees in a graph can be used to determine whether a given vertex partition is Frieze–Kannan regular. With a more refined version of these two local conditions we provide a deterministic algorithm that obtains a Frieze–Kannan regular partition of any graphGin timeO(|V(G)|2).
The Content, Quality and Impact of Cognitive Behavioural Case Formulation During Treatment of Obsessive Compulsive Disorder
Authors: Nattrass Anna , Kellett Stephen , Hardy Gillian E. , Ricketts Tom
Published: April 2014

Background: Case formulation (CF) is considered a core component of cognitive behavioural therapy (CBT). Despite this, few studies have explored the content and quality of CFs in routine practice and any associated impact on treatment outcome. Aims: This study investigated (1) the content, timing and quality of CF for patients (N = 29) with Obsessive Compulsive Disorder; (2) the impact of CF on symptoms, distress and therapeutic alliance; and (3) the relationship between CF quality and treatment outcome. Method: CF content and quality were assessed from audiotapes of routine CBT sessions using a validated coding manual and evaluated against treatment outcomes at different stages of therapy. Results: CFs were developed early during treatment and contained strong behavioural and cognitive components, with a focus on symptoms and maintaining factors. CF quality ratings ranged from rudimentary to excellent. A significant improvement in distress and the therapeutic alliance occurred following the introduction of CF, but no significant relationship was found between CF quality and outcome at any stage of treatment. Conclusion: CF may be valuable in reducing patient attrition, due to its impact early in treatment. Further research is needed to explore the most important components of CF. Theoretically sound and disorder specific measurement tools for evaluating CFs are required.
PUBLIC SPENDING AS A SOURCE OF ENDOGENOUS BUSINESS CYCLES IN A RAMSEY MODEL WITH MANY AGENTS
Authors: Nishimura Kazuo , Nourry Carine , Seegmuller Thomas , Venditti Alain
Published: April 2014

We introduce public spending, financed through income taxation, into the Ramsey model with heterogeneous agents. Public spending as a source of welfare generates more complex dynamics. In contrast to previous contributions focusing on similar models but with wasteful public spending, limit cycles through Hopf bifurcation and expectation-driven fluctuations appear if the degree of capital–labor substitution is high enough to be compatible with capital income monotonicity. Moreover, unlike frameworks with a representative agent, our results do not require externalities in production and are compatible with a weakly elastic labor supply with respect to wage.
The Near Edge Structure of Hexagonal Boron Nitride
Authors: McDougall Nicholas L. , Nicholls Rebecca J. , Partridge Jim G. , McCulloch Dougal G.
Published: April 2014

Hexagonal boron nitride (hBN) is a promising material for a range of applications including deep-ultraviolet light emission. Despite extensive experimental studies, some fundamental aspects of hBN remain unknown, such as the type of stacking faults likely to be present and their influence on electronic properties. In this paper, different stacking configurations of hBN are investigated using CASTEP, a pseudopotential density functional theory code. AB-b stacking faults, in which B atoms are positioned directly on top of one another while N atoms are located above the center of BN hexagons, are shown to be likely in conventional AB stacked hBN. Bandstructure calculations predict a single direct bandgap structure that may be responsible for the discrepancies in bandgap type observed experimentally. Calculations of the near edge structure showed that different stackings of hBN are distinguishable using measurements of core-loss edges in X-ray absorption and electron energy loss spectroscopy. AB stacking was found to best reproduce features in the experimental B and N K-edges. The calculations also show that splitting of the 1stoπ* peak in the B K-edge, recently observed experimentally, may be accounted for by the presence of AB-b stacking faults.
Results of a Canadian study examining the prevalence and potential for developing compassion fatigue and burnout in radiation therapists
Authors: Gillies Carol , Bristow Bonnie , Gallant Francois , Osmar Kari , Lange-Mechlen Irene , Tran William Tyler
Published: April 2014

Objective

Caring is a fundamental tenet of healthcare. Caring ‘too much’ can result in compassion fatigue syndrome and is often linked to burnout and low morale. The objective of this study was to examine compassion fatigue, secondary traumatic stress (STS) and burnout by investigating the relationship between levels of compassion (compassion satisfaction) and STS and burnout. The study also aimed to identify radiation therapist (RTTs) groups who may be at risk for developing (STS) and burnout. Finally, we investigated the level of social support that RTTs receive.

Methods

RTTs practicing across Canada were invited to participate in an electronic questionnaire. The questionnaire consisted of: demographic information including health-related issues and occupational variables; the Professional Quality of Life Compassion Satisfaction and Fatigue Questionnaire (ProQOL-V) to assess the potential for compassion satisfaction and vulnerability for STS and burnout; and the Multidimensional Scale of Perceived Social Support (MSPSS) to examine the level and sources of social support. A two-way ANOVA was performed to test the statistical significance between varying groups within the study population. A linear regression analysis using potential co-factors was used to test correlations between compassion fatigue, compassion satisfaction and burnout and variables in age, education, years of experience and levels of caring to patients.

Results

A total of 477 survey responses were received representing a 36% response rate. Results of the regression analyses generally indicate inverse correlations between the risks associated with compassion satisfaction, burnout and STS compared with the independent study variables of age, education, years of experience and levels of caring to patients. It was observed that responses were not linear within subgroups (age groups, education classifications, years of study).

Conclusion

RTTs practicing in Canada have a substantial social support network and demonstrate high levels of compassion satisfaction in their daily practice. The results of the study indicate that compassion levels are inversely correlated with burnout and compassion fatigue, although some groups may be at higher risk than others. A possible risk catalyst for compassion fatigue and burnout is associated with underdeveloped managerial workplace support programmes.
Image guidance procedures in radiotherapy for prostate cancer and the influence of body mass index
Authors: Piotrowski Tomasz , Kaczmarek Krzysztof , Jodda Agata , Ryczkowski Adam , Bajon Tomasz , Rodrigues George , Yartsev Slav
Published: April 2014

Purpose

To investigate possible optimisation of the image guidance procedure for the prostate cancer patients with respect to imaging frequency and patient body mass index (BMI).

Methods

The 6,085 setup correction shifts and BMI for 216 prostate cancer patients treated on tomotherapy units in two centres were analysed. Margins needed to account for inter-fraction target motion with daily only automatic correction and with automatic and manual corrections during one, three or five first fractions as a reference for further treatment without imaging were calculated.

Results

The planning target volume margin calculated for the daily automatic correction only scheme was significantly lower than the margins calculated for the image guidance limited to a few initial fractions. Manual corrections after automatic fusion were more important for patients with higher BMI. On average, the patients with normal BMI had manual correction shift of 0·7 mm in anterioposterior direction, while overweight and obese patients required, correspondingly, the shifts of 1·3 and 1·4 mm.

Conclusion

Overweight and obese patients require daily imaging with time saving available by performing automatic kV/MV computed tomography registration only. The patients with normal BMI may be treated with imaging guidance during a few initial treatment fractions.

This study examines the process by which the concept of quality of life has been increasing in importance as the key to ASEAN's socio-cultural integration. This study also focuses on the current trend that emphasizes subjective quality of life and clarifies that ASEAN has been moving toward including this perspective. Then, it analyzes the subjective quality of life of people in ASEAN in terms of self-assessment and the multidimensional World Health Organization Quality of Life metric by using data from the ASEAN Barometer 2009.
Environmental Consciousness of ASEAN Citizens
Authors: SASAOKA SHINYA
Published: April 2014

The Association of South East Asian Nations (ASEAN) countries has fostered economic growth recently but in the process has encountered a number of serious problems regarding environmental destruction, such as the air and water pollution. In addition, due to rapid population growth and urbanization, there are emerging concerns about decline of the environment in those countries in the near future. One of the surveys that tries to measure the attitudes of ASEAN citizens on environmental issues is the ASEAN Barometer survey conducted in 2009. This paper aims to unfold how ASEAN citizens evaluate environmental problems and what underlie their evaluations using the aforementioned ASEAN Barometer survey. The results of analysis will mainly reveal the next three points: (1) Filipinos showed higher environmental consciousness; (2) people in a less developed country were more likely to worry about environment deterioration and showed more commitment to the environmental movement, but, at the same time, they were more reticent about their immediate ecological activities; (3) those who thought that central governments needed to commit more to environmental problems and should take greater responsibility for environmental deterioration. Those who expected regional international organizations to take more measures were more inclined to engage in environmental activities.
The Rise of Consumer–Oriented Politics in Japan? Exploring the Party–Citizen Relationship through Discourse Analysis
Authors: SAUZIER-UCHIDA EMI
Published: April 2014

This article analyses the discourse of three prime ministers – Koizumi, Aso, and Hatoyama – to explore how each leader identified the political self and constructed and promoted a particular relationship with the voter before the general elections. The outcome indicates the emergence of a new political communication style based on a party–citizen relationship as business–consumer. Whereas Aso's patron–client discourse pinpoints the role of the responsible and bureaucratic state in protecting Japan, the business–consumer discourse of both Koizumi and Hatoyama demonstrates the entrepreneurial leaders’ willingness to listen to individuals in order to meet their needs and expectations. We speculate that the social norms and values of the business–consumer model might have played a role in attracting a large number of unorganized voters to Koizumi in 2005 and in turn to Hatoyama in 2009.
Expressiveness and Voting Decision: New Evidence from the Korean Parliamentary Election
Authors: JOO MAN-SOO , YUN SUNGHO
Published: April 2014

According to the expressive view of voting, a voter derives expressive utility from casting a vote. We present two possible sources of expressive utility: social interaction with voters having the same political preferences, and interestingness of the election. First, it has been suggested that a voter's expressive utility may increase when there are more voters having the same political preference. We extend this line of study and test the hypothesis that a voter's expressive utility increases as the number of voters having the same political preferences increases in thelocalcommunity, where interaction occurs more frequently with others than it does with others in distant communities. Second, we propose and test the other hypothesis, that voters’ expressive utility is larger when the election is more interesting. Using 2008 parliamentary election data from Korea, where the election consists of both 245 single-member districts and only one nationwide district for proportional representatives, we find supporting evidence for these two arguments: the turnout rate is significantly and positively related to the share of proportional representation votes for the largest party in each single-member district; the turnout rate is also significantly and positively related to the number of polls for single-member district election conducted by major broadcasting companies, which we use as a proxy variable for interestingness of the election.
South Asian Regional Integration – Challenges and Prospects
Authors: KARIM MOHD AMINUL
Published: April 2014

South Asian regional integration is seemingly confronting many challenges. The aim of this paper is to identify those challenges and also look for prospects. Although regional integration in South Asia has adopted a kind of institutionalization, it is yet to deliver any concrete outcomes. High-politics and the not-so-conducive regional economic structures hinder any effectual culmination. However, constructivism, as a theory, is given due credence in this paper when looking for future prospects. The paper highlights the issues, and attempts to offer certain policy directions by analyzing the challenges and identifying the prospects in the on-going integration/cooperation process.
What Is Political Science For?
Authors: Mansbridge Jane
Published: April 2014

This address advances three ideas. First, political science as a discipline has a mandate to help human beings govern themselves. Second, within this mandate we should be focusing, more than we do now, on creating legitimate coercion. In a world of increasing interdependence we now face an almost infinite number of collective action problems created when something we need or want involves a “free-access good.” We need coercion to solve these collective action problems. The best coercion is normatively legitimate coercion. Democratic theory, however, has focused more on preventing tyranny than on how to legitimate coercion. Finally, our discipline has neglected an important source of legitimate coercion: negotiation to agreement. Recognizing the central role of negotiation in politics would shed a different light on our relatively unexamined democratic commitments to transparency in process and contested elections. This analysis is overall both descriptive and aspirational, arguing that helping human beings to govern themselves has been in the DNA of our profession since its inception.
Sex-Classification Policies as Transgender Discrimination: An Intersectional Critique
Authors: Davis Heath Fogg
Published: April 2014

Sex-classification policies are unjust because they prompt and authorize administrative agents to use their own subjective gender judgments to target, inspect, and exclude transgender-appearing people from the public accommodations under their watch. The vast majority of sex-classification policies are not rationally related to legitimate policy goals because there is no objective, socially agreed upon test for determining who is male and who is female, and legitimate policy goals such as fraud prevention, safety, security, and privacy can almost always be met more effectively by alternative means that do not subject people to gender inspection. I make a legal-normative argument for using gender-identity antidiscrimination laws to abolish sex-classification policies. I ground this radical proposal in a modified liberalism that treats sexual self-definition as an integral feature of liberal self-definition. Gender and intersectionality theorists rightly point out the deep structure of race-sex-class perception and oppression, but many of these theorists are too quick to dismiss the radical potential of gender-identity discrimination laws to eliminate, rather than modify, longstanding sex-classification policies. Racial, class and gender perception intersect to generate the possibility, rather than the inevitability, of invidious sex administration. And that is more than enough reason to abandon sex-classification policies.
“A Rush and a Push and the Land Is Ours”: Territorial Expansion, Land Policy, and U.S. State Formation
Authors: Frymer Paul
Published: April 2014

I examine the role of US land policy in strategically controlling and moving populations around the continent with the goal of expanding borders and securing and incorporating new territory on the frontier. The government effectively used land policies and population control to enable an otherwise constrained American state to assert authority over the direction of expansion, to engineer settlement patterns in a manner to secure the territory without a large military, and to maintain an official fidelity to constitutional principles while engineering a dominant racial vision. I examine both the success and failures of these policies over the nineteenth century, with material drawn from government documents and primary sources. I discuss the consequences of this land policy for how we understand the American state in the context of comparative state and racial formation.
The political economy of rationing health care in England and the US: the ‘accidental logics’ of political settlements
Authors: Bevan Gwyn , Brown Lawrence D.
Published: April 2014

This article considers how the ‘accidental logics’ of political settlements for the English National Health Service (NHS) and the Medicare and Medicaid programmes in the United States have resulted in different institutional arrangements and different implicit social contracts for rationing, which we define to be the denial of health care that is beneficial but is deemed to be too costly. This article argues that rationing is designed into the English NHS and designed out of US Medicare; and compares rationing for the elderly in the United States and in England for acute care, care at the end of life, and chronic care.
The global burden of mental and substance use disorders: changes in estimating burden between GBD1990 and GBD2010
Authors: Baxter A. J. , Ferrari A. J. , Erskine H. E. , Charlson F. J. , Degenhardt L. , Whiteford H. A.

Background.

The main aim of this paper is to compare and contrast the methodological approaches of the new Global Burden of Disease 2010 Study (GBD 2010) with the original study conducted for 1990 (GBD 1990), in terms of calculating burden for mental and substance use disorders.

Methods.

We reviewed the conceptual and methodological changes to GBD burden calculations in the GBD 2010 study, compared with previous studies. We then discuss the possible implications of these changes with respect to burden estimates for mental and substance use disorders.

Results.

It is not possible to compare burden estimates arising from the GBD 1990 study with the most recent burden estimates. There have been important advances in the categorisation and definition of mental disorders, and the input and computation of epidemiological models for disease distribution. There have also been major changes to conceptual and social value choices aimed at addressing concerns that arose following publication of earlier GBD studies.

Conclusion.

Advancements to the GBD conceptual framework and method of calculating burden estimates has led to more accurate and equitable consideration of the burden for mental and substance use disorders. Proposed annual updates of GBD estimates by the Institute of Health Metrics and Evaluation provide an opportunity to continue to advance the evidence base that underpins the quantification of disease burden.
Worte vor Taten – der Stellenwert der Beratung in der Ära des Praena-Tests
Authors: Tschudin Sibil
Published: April 2014

Immer neue Angebote in der Pränataldiagnostik stellen Schwangere vor die Wahl. In der Schweiz sind ÄrztInnen verpflichtet, vor pränatalen Untersuchungen zu informieren und das Einverständnis einzuholen. Angesichts der Komplexität der Informationen und der Konsequenzen eines positiven Befundes ist diese Beratung insbesondere im interkulturellen Kontext anspruchsvoll. Eine Fragebogenstudie verglich die Informationsverarbeitung, Ergebnisinterpretation und emotionale Reaktion von aus der Schweiz und anliegenden EU-Staaten stammenden Schwangeren mit solchen aus der Türkei. Es zeigte, dass die Kenntnisse Letzterer geringer waren und sie sich durch die Beratung eher verunsichert fühlten bei gleichzeitig signifikant höherer Akzeptanz gegenüber der Pränataldiagnostik. Eine empathische Grundhaltung und die richtigen Worte sind entscheidend und ihr Stellenwert wird mit der Zunahme der Optionen, die Patientinnen zur Verfügung stehen, noch an Bedeutung gewinnen.
