Résumé
Les auteurs rapportent une observation d’une plaie de la verge par embrochage d’une esquille de bois lors de l’activité quotidienne d’un menuisier. Le patient a été reçu trois heures après l’accident de travail. L’esquille de bois avait transpercé la verge de part en part, avec arrêt au niveau de la cuisse gauche. L’exploration chirurgicale a retrouvé une plaie d’environ 1,5 × 3 cm des corps caverneux, sans atteinte visible de l’urètre, et une effraction du muscle quadriceps. Le risque de dysfonction érectile secondaire au traumatisme des corps caverneux a été évoqué.
Suspensions with a tunable effective viscosity: a numerical study
Authors: Jibuti L. , Rafaï S. , Peyla P. 
Published: January 2012

AbstractIn this paper, we conduct a numerical investigation of sheared suspensions of non-colloidal spherical particles on which a torque is applied. Particles are mono-dispersed and neutrally buoyant. Since the torque modifies particle rotation, we show that it can indeed strongly change the effective viscosity of semi-dilute or even more concentrated suspensions. We perform our calculations up to a volume fraction of 28 %. And we compare our results to data obtained at 40 % by Yeo and Maxey (Phys. Rev.E, vol. 81, 2010, p. 62501) with a totally different numerical method. Depending on the torque orientation, one can increase (decrease) the rotation of the particles. This results in a strong enhancement (reduction) of the effective shear viscosity of the suspension. We construct a dimensionless number$\Theta $which represents the average relative angular velocity of the particles divided by the vorticity of the fluid generated by the shear flow. We show that the contribution of the particles to the effective viscosity can be suppressed for a given and unique value of$\Theta $independently of the volume fraction. In addition, we obtain a universal behaviour (i.e. independent of the volume fraction) when we plot the relative effective viscosity divided by the relative effective viscosity without torque as a function of$\Theta $. Finally, we show that a modified Faxén law can be equivalently established for large concentrations.
Bilateral maxillary mucoceles: an unusual presentation of cystic fibrosis
Authors: Qureishi A , Lennox P , Bottrill I 
Published: January 2012

AbstractObjective:We report a rare case of bilateral maxillary mucoceles. This was the primary presentation in a child with an underlying diagnosis of cystic fibrosis.Case report:A five-month-old infant presented with isolated symptoms of nasal congestion. Initial examination and investigation with computed tomography identified the cause to be bilateral maxillary mucoceles. The child was investigated for cystic fibrosis and found to be positive. Given the young age and anatomy, a modified surgical approach was used to treat the mucoceles, comprising endoscopic and bilateral uncapping of the maxillary mucocele, uncinectomy, and middle meatal antrostomy. The child was then followed up with appropriate treatment for cystic fibrosis. At six-week follow up, there was no recurrence of symptoms.Conclusion:Maxillary mucoceles are extremely rare but can present in patients with chronic sinusitis or cystic fibrosis. To our knowledge, there are no prior reports of this condition being the primary indicator of underlying cystic fibrosis in the absence of upper respiratory tract symptoms. Doctors should be aware that mucoceles can present in very young individuals and may indicate an underlying diagnosis of cystic fibrosis. A high index of clinical suspicion will avoid delays in diagnosis and long-term management.
Measuring Subjective Wellbeing: Recommendations on Measures for use by National Governments
Authors: DOLAN PAUL , METCALFE ROBERT 
Published: January 2012

AbstractGovernments around the world are now beginning to seriously consider the use of measures of subjective wellbeing (SWB) – ratings of thoughts and feelings about life – for monitoring progress and for informing and appraising public policy. The mental state account of wellbeing upon which SWB measures are based can provide useful additional information about who is doing well and badly in life when compared to that provided by the objective list and preference satisfaction accounts. It may be particularly useful when deciding how best to allocate scarce resources, where it is desirable to express the benefits of intervention in a single metric that can be compared to the costs of intervention. There are three main concepts of SWB in the literature – evaluation (life satisfaction), experience (momentary mood) and eudemonia (purpose) – and policy-makers should seek to measure all three, at least for the purposes of monitoring progress. There are some major challenges to the use of SWB measures. Two related and well-rehearsed issues are the effects of expectations and adaptation on ratings. The degree to which we should allow wellbeing to vary according to expectations and adaptation are vexing moral problems but information on SWB can highlight what difference allowing for these considerations would have in practice (e.g. in informing prioiritisation decisions), which can then be fed into the normative debate. There are also questions about precisely what attention should be drawn to in SWB questions and how to capture the ratings of those least inclined to take part in surveys, but these can be addressed through more widespread use of SWB. We also provide some concrete recommendations about precisely what questions should be asked in large-scale surveys, and these recommendations have been taken up by the Office of National Statistics in the UK and are being looked at closely by the OECD.
Residential proximity of nearest child and older adults’ receipts of informal support transfers in Barbados
Authors: QUASHIE NEKEHIA , ZIMMER ZACHARY 
Published: January 2012

ABSTRACTThis study assesses the probability that an older person in Bridgetown, Barbados receives financial, functional and/or material support from their adult children according to the proximity of their nearest child, adjusting for demographic and socio-economic factors. As in many countries of the developing world, older Barbadians receive much of their support from adult children. Population ageing, smaller family sizes and high rates of out-migration may be placing stress on systems of formal and informal support within the country. Yet, very little research has examined determinants of support within the Caribbean let alone Barbados, one of the most rapidly ageing countries in the region. Data (N = 1,248) come from the 2000 Pan American Health Organization Survey on Health, Well-being and Ageing in Latin America and the Caribbean (SABE). Multivariate logistic regression analyses highlight the overwhelming importance of co-residence in the receipt of informal support transfers. Although there is a lower probability of receiving support as distance to nearest child increases, several indicators of vulnerability, such as having a disability, increases support probabilities among those whose nearest children live outside the neighbourhood. The results have implications for current and future cohorts of older adults in the region given the combination of declining fertility, persistent migration and population ageing within a broader context of social protection systems across the region.
Process of optimisation for a 4 DOF tele-echography robot
Authors: Nouaille L. , Vieyres P. , Poisson G. 
Published: January 2012

SUMMARYThis paper deals with processes of optimisation for the design of a four degree-of-freedom robot dedicated to remote ultrasound tele-echography. This robot is designed to track the medical gestures of a remote expert moving an ultrasound probe. The goal is to optimise the kinematic structure by fixing the geometric parameters; these have a significant role in robot configuration singularities, with respect to current medical gestures and mechanism compactness. After choosing a dedicated kinematic structure, several optimisations are presented. Then an optimal choice of geometrical parameters of a global function in relation with kinematic performance indices and compactness is proposed. This robot is soon to be used in the experimental medical phase of the Prosit project.
Singularity analysis of the H4 robot using Grassmann–Cayley algebra
Authors: Amine Semaan , Caro Stéphane , Wenger Philippe , Kanaan Daniel 
Published: January 2012

SUMMARYThis paper extends a recently proposed singularity analysis method to lower-mobility parallel manipulators having an articulated nacelle. Using screw theory, a twist graph is introduced in order to simplify the constraint analysis of such manipulators. Then, a wrench graph is obtained in order to represent some points at infinity on the Plücker lines of the Jacobian matrix. Using Grassmann–Cayley algebra, the rank deficiency of the Jacobian matrix amounts to the vanishing condition of the superbracket. Accordingly, the parallel singularities are expressed in three different forms involving superbrackets, meet and join operators, and vector cross and dot products, respectively. The approach is explained through the singularity analysis of the H4 robot. All the parallel singularity conditions of this robot are enumerated and the motions associated with these singularities are characterized.
From stable walking to steering of a 3D bipedal robot with passive point feet
Authors: Shih Ching-Long , Grizzle J. W. , Chevallereau Christine 
Published: January 2012

SUMMARYThis paper exploits a natural symmetry present in a 3D robot in order to achieve asymptotically stable steering. The robot under study is composed of 5-links and unactuated point feet; it has 9 DoF (degree-of-freedom) in the single-support phase and six actuators. The control design begins with a hybrid feedback controller that stabilizes a straight-line walking gait for the 3D bipedal robot. The closed-loop system (i.e., robot plus controller) is shown to be equivariant under yaw rotations, and this property is used to construct a modification of the controller that has a local, but uniform, input-to-state stability (ISS) property, where the input is the desired turning direction. The resulting controller is capable of adjusting the net yaw rotation of the robot over a step in order to steer the robot along paths with mild curvature. An interesting feature of this work is that one is able to control the robot's motion along a curved path using only a single predefined periodic motion.
UPDATING CLINICAL PRACTICE RECOMMENDATIONS: IS IT WORTHWHILE AND WHEN?
Authors: Lyratzopoulos Georgios , Barnes Steven , Stegenga Heather , Peden Suzi , Campbell Bruce 
Published: January 2012

Background: Keeping clinical practice recommendations up-to-date with a continually evolving evidence base presents challenges. Resources required to update recommendations compete with those needed to evaluate newer treatments.Methods: We describe an approach developed by the UK National Institute for Health and Clinical Excellence (NICE) for updating clinical practice recommendations for new interventional procedures and we evaluate relevant initial experience of using this system. Depending on whether evidence for a procedure is judged adequate or inadequate for safety and efficacy, use in clinical practice is usually recommended with either “normal” or “special” arrangements for patient consent, data collection and institutional oversight, respectively. We examined whether differences in the state of the evidence at the initial and the updated appraisal of procedures were associated with changed recommendations.Results: Since 2008, updating of recommendations focuses on procedures with initially inadequate evidence. “Special arrangements” recommendations about eleven procedures were updated after 3.3–6.5 years (median, 5.3 years), and recommendations for six were changed to “normal arrangements.” Overall, procedures with changed (“special-to-normal”) recommendations had a greater increase in the number of patients included in observational studies published since the initial guidance.Conclusions: Procedures with changed (“special-to-normal”) recommendations generally had greater increases in their evidence base. Although uncertainties about optimal methods for keeping evidence-based recommendations up-to-date remain, this experience should be useful to policy makers in developing processes for prioritizing scarce resources for updating clinical practice recommendations. Further studies are needed about the value placed on “updated” recommendations by clinicians, policy-makers, and patients.
Generating example contexts to help children learn word meaning
Authors: LIU LIU , MOSTOW JACK , AIST GREGORY S. 
Published: January 2012

AbstractThis article addresses the problem of generating good example contexts to help children learn vocabulary. We describe VEGEMATIC, a system that constructs such contexts by concatenating overlapping five-grams from Google's N-gram corpus. We propose and operationalize a set of constraints to identify good contexts. VEGEMATIC uses these constraints to filter, cluster, score, and select example contexts. An evaluation experiment compared the resulting contexts against human-authored example contexts (e.g., from children's dictionaries and children's stories). Based on rating by an expert blind to source, their average quality was comparable to story sentences, though not as good as dictionary examples. A second experiment measured the percentage of generated contexts rated by lay judges as acceptable, and how long it took to rate them. They accepted only 28% of the examples, but averaged only 27 seconds to find the first acceptable example for each target word. This result suggests that hand-vetting VEGEMATIC's output may supply example contexts faster than creating them manually.

AbstractIn this paper, we describe a novel approach to computational modeling and understanding of social and cultural phenomena in multi-party dialogues. We developed a two-tier approach in which we first detect and classify certain sociolinguistic behaviors, including topic control, disagreement, and involvement, that serve as first-order models from which presence the higher level social roles, such as leadership, may be inferred.

Published: January 2012

A statistical investigation into the horizontal propagation of ∼8–30 min gravity waves (GWs) in the ionosphere over a 1 year period from June 2010 to May 2011 is presented. The GWs were observed by multipoint continuous Doppler sounding systems installed in the Czech Republic and in the Western Cape, South Africa. Measurements of GW propagation in the ionosphere over South Africa have never been presented before. Simultaneous measurements from nearby ionosondes made it possible to estimate the height of the GW observations and show that the analyzed GWs propagated at altitudes from ∼150 to ∼250 km. The analyzed waves were mainly observed after sunrise and around sunset. Our statistical study shows that the analyzed GWs propagated with horizontal velocities from ∼70 to 250 m/s. The average observed horizontal velocities were ∼100 m/s in the local summer and 125–150 m/s in the local winter. The waves propagated approximately poleward in the local summer, whereas roughly equatorward propagation was observed in the local winter. Westward propagation was rarely observed in the Czech Republic, and eastward (southeast) propagation was seldom observed in South Africa. A comparison with neutral wind velocities shows that the analyzed GWs propagated approximately against the neutral winds calculated by the HWM07 model. The estimated horizontal wavelengths of the analyzed waves were ∼100–300 km.
Advanced ceramic matrix composites for high energy x-ray generation
Authors: Khan Amir Azam , Labbe Jean Claude 
Published: January 2012

Abstract
High energy x-ray targets are the anodes used in high performance tubes, designed to work for long operating times and at high power. Such tubes are used in computed tomography (CT) scan machines. Usually the tubes used in CT scanners have to continuously work at high temperatures and for longer scan durations in order to get maximum information during a single scan. These anodes are composed of a refractory substrate which supports a refractory metallic coating. The present work is a review of the development of a ceramic metal composite based on aluminium nitride (AlN) and molybdenum for potential application as the substrate. This composite is surface engineered by coating with tungsten, the most popular material for high energy x-ray targets. To spray metallic coatings on the surface of ceramic matrix composites dc blown arc plasma is employed. The objective is to increase the performance and the life of an x-ray tube. Aluminium nitride-molybdenum ceramic matrix composites were produced by uniaxial hotpressing mixtures of AlN and Mo powders. These composites were characterized for their mechanical, thermal, electrical and micro-structural properties. An optimized composition was selected which contained 25 vol.% of metallic phase dispersed in the AlN matrix. These composites were produced in the actual size of an anode and coated with tungsten through dc blown arc plasma spraying. The results have shown that sintering of large size anodes is possible through uniaxial pressing, using a modified sintering cycle.
IMID: integrated molecular interaction database
Authors: Balaji Sentil , Mcclendon Charles , Chowdhary Rajesh , Liu Jun S. , Zhang Jinfeng 
Published: January 2012

Abstract
Motivation: Molecular interaction information, such as protein–protein interactions and protein–small molecule interactions, is indispensable for understanding the mechanism of biological processes and discovering treatments for diseases. Many databases have been built by manual annotation of literature to organize such information into structured form. However, most databases focus on only one type of interactions, which are often not well annotated and integrated with related functional information.
Results: In this study, we integrate molecular interaction information from literature by automatic information extraction and from manually annotated databases. We further integrate the relationships between protein/gene and other bio-entity terms including gene ontology terms, pathways, species and diseases to build an integrated molecular interaction database (IMID). Interactions can be selected by their associated probabilities. IMID allows complex and versatile queries for context-specific molecular interactions, which are not available currently in other molecular interaction databases.

Feminist Theology and the Jewish Tradition
Authors: Raphael Melissa 
Published: January 2012

Abstract
Building on the foundations of First Wave Jewish and Christian women's activism, Jewish feminist theology has made a decisive contribution to the post-Holocaust renewal of Jewish thought. Its vision of Israel as an assembly of gendered persons whose ethical relationships with the world and with one another are witness to the love and justice of God has introduced inclusive language into the liturgy, and has expanded the linguistic and imaginal range of Jewish evocations of God. In doing so, Jewish feminist theology has established the theological terms on which to affirm the full humanity of Jewish women as subjects and agents of their own Jewish experience. This chapter begins by outlining the denominational and postdenominational contexts of Jewish feminist theology and assessing its standing in the primarily Anglophone Jewish community in which it has established itself since the second half of the 1970s. It then moves on to examine the ideas and approaches of a number of Jewish feminist theology's key practitioners, and some of the challenges it is likely to face over the coming years.
What is Feminist Theology?
Authors: Briggs Sheila 
Published: January 2012

AbstractThis chapter attempts to renew and develop under the present conditions of globalization the position that theological insight can be gained from the materiality of human lives, in which physical processes and cultural representations are inextricably bound together. To this end, it explores two areas in which little feminist theological work is currently being done, and which are crucial to the operations of globalization and our understanding of them: science and technology, and popular culture.
Transethnic Feminist Theology of Asia: Globalization, Identities, and Solidarities
Authors: Kang Namsoon 
Published: January 2012

Abstract
This chapter proposes a transethnic feminist theology of Asia, where one's ethnicity can be an entry point but where one moves beyond geographic, cultural, or ethnic boundaries and interests. This transethnic perspective requires a radical ecumenical spirit which adopts a very dialectical approach to race, ethnicity, and culture, and a fundamental awareness that the local, the particular, or the ethnic has always been shaped by the global and the global by the local. This transethnic perspective ought to produce not a blind universalism but a relational and dialectical universalism that promotes “shared sensibilities” across the boundaries of class, gender, race, ethnicity, ability, or orientation without sacrificing the particular situatedness of one's geopolitical and discursive location. This transethnic positionality further establishes a firm ground for the “recognition of common commitments” and will “serve as a base for solidarity and coalition” amongst those who work for the betterment of our society.
