A Novel Method for the 3-D Reconstruction of Scoliotic Ribs From Frontal and Lateral Radiographs

Among the external manifestations of scoliosis, the rib hump, which is associated with the ribs' deformities and rotations, constitutes the most disturbing aspect of the scoliotic deformity for patients. A personalized 3-D model of the rib cage is important for a better evaluation of the deformity, and hence, a better treatment planning. A novel method for the 3-D reconstruction of the rib cage, based only on two standard radiographs, is proposed in this paper. For each rib, two points are extrapolated from the reconstructed spine, and three points are reconstructed by stereo radiography. The reconstruction is then refined using a surface approximation. The method was evaluated using clinical data of 13 patients with scoliosis. A comparison was conducted between the reconstructions obtained with the proposed method and those obtained by using a previous reconstruction method based on two frontal radiographs. A first comparison criterion was the distances between the reconstructed ribs and the surface topography of the trunk, considered as the reference modality. The correlation between ribs axial rotation and back surface rotation was also evaluated. The proposed method successfully reconstructed the ribs of the 6th-12th thoracic levels. The evaluation results showed that the 3-D configuration of the new rib reconstructions is more consistent with the surface topography and provides more accurate measurements of ribs axial rotation.

To say or not to say : dyadic ambivalence over emotional expression and its associations with pain, sexuality, and distress in couples coping with provoked vestibulodynia.

Introduction Provoked vestibulodynia (PVD) is a highly prevalent and taxing female genital pain condition. Despite the intimate nature of this pain and the fact that affective factors such as anxiety have been shown to modulate its manifestations, no study has yet explored the emotional regulation of couples in which the woman suffers from PVD. Aim Ambivalence over emotional expression (AEE) is an emotional regulation variable that quantifies the extent to which a person is comfortable with the way she or he expresses emotions. We examined whether the dyadic AEE of couples in which the woman suffers from PVD was differentially associated with women's pain and couples' psychological, sexual, and relational functioning. Methods Couples (N = 254), in which the woman suffered from PVD, completed the AEE questionnaire. A couple typology of dyadic AEE was created. Main Outcome Measures Dependent measures for both members of the couple were the global measure of sexual satisfaction scale, the Beck depression inventory II, and the revised dyadic adjustment scale. The female sexual function index and the sexual history form were used to assess the sexual function of women and men, respectively. Women also completed the pain rating index of the McGill pain questionnaire. Results Couples, in which both partners were considered low on AEE, had the highest scores on sexual satisfaction (P = 0.02) and function (P < 0.01), the lowest depression scores (P < 0.01), and the best dyadic adjustment (P = 0.02). No difference in pain intensity was found between couples. Conclusions Findings suggest that, for couples in which the woman suffers from PVD, an emotional regulation that is low in ambivalence in both partners is associated with better psychological, sexual, and relational outcomes. Results indicate that emotional regulation may be important to consider in the assessment and treatment of couples coping with PVD.

Quand la réadaptation blesse? Éducateurs victimes de violence

Cette étude vise à comprendre le phénomène de la violence physique vécue par les éducateurs oeuvrant dans dix Centres Jeunesse (CJ) du Québec. Pour ce faire, un sondage de victimisation a été administré à 586 éducateurs en internat. En premier lieu, la prévalence de cette problématique sera établie. Par la suite, les facteurs individuels et environnementaux prédisposant aux agressions physiques seront identifiés. Des éducateurs sondés, 53,9 % rapportent avoir été victimes de violence physique au cours de la dernière année. Sur le plan individuel, être affecté par les manifestations agressives des clients et la fréquence des violences psychologiques subies augmentent les risques de victimisation physique. Quant au contexte, l’âge de la clientèle et le motif de l’intervention (basé sur la loi justifiant le placement) auprès de l’enfant ou de l’adolescent influencent l’occurrence des actes violents dirigés contre les éducateurs. Nos analyses montrent également que les violences physiques dont sont victimes les éducateurs affectent autant l’individu que l’institution. L’identification de facteurs permettant de prédire les risques de victimisation pourrait notamment servir à orienter les programmes de prévention de la violence dans les CJ, mais aussi à cibler les éducateurs les plus à risque afin de leur fournir un soutien adapté.

Gravity Modelling of the Crustal Structure Below Bavali Shear Zone And Adjacent Major Plutons Of Northern Kerala

The primary aim of the present study is to acquire a large amount of gravity data, to prepare gravity maps and interpret the data in terms of crustal structure below the Bavali shear zone and adjacent regions of northern Kerala. The gravity modeling is basically a tool to obtain knowledge of the subsurface extension of the exposed geological units and their structural relationship with the surroundings. The study is expected to throw light on the nature of the shear zone, crustal configuration below the high-grade granulite terrain and the tectonics operating during geological times in the region. The Bavali shear is manifested in the gravity profiles by a steep gravity gradient. The gravity models indicate that the Bavali shear coincides with steep plane that separates two contrasting crustal densities extending beyond a depth of 30 km possibly down to Moho, justifying it to be a Mantle fault. It is difficult to construct a generalized model of crustal evolution in terms of its varied manifestations using only the gravity data. However, the data constrains several aspects of crustal evolution and provides insights into some of the major events.

Parity violation in Aharonov-Bohm systems: The spontaneous Hall effect

We show how macroscopic manifestations of P (and T) symmetry breaking can arise in a simple system subject to Aharonov-Bohm interactions. Specifically, we study the conductivity of a gas of charged particles moving through a dilute array of flux tubes. The interaction of the electrons with the flux tubes is taken to be of a purely Aharonov-Bohm type. We find that the system exhibits a nonzero transverse conductivity, i.e., a spontaneous Hall effect. This is in contrast to the fact that the cross sections for both scattering and bremsstrahlung (soft-photon emission) of a single electron from a flux tube are invariant under reflections. We argue that the asymmetry in the conductivity coefficients arises from many-body effects. On the other hand, the transverse conductivity has the same dependence on universal constants that appears in the quantum Hall effect, a result that we relate to the validity of the mean-field approximation.

Lease Financing in India",

Several related articles have appeared ix: journals and dailies, covering mainly the advantages and disadvantages of leasing. Some have focussed on the leasing scenario in India while others projected the prospects of leasing. However, there are some research articles worth mentioning. An exploratory study done by R. Narayana Swamy expresses -the views of leasing companies, on lease accounting issues in India. It deals only with several aspects of accounting regulation, accounting standard setting, accounting proposals and implications and economic consequences of the proposals for leasing companies and for lessees and users of financial statamnts. Another article dealing with the growth and performance of leasing industry by Rita Vasanls gives just a peripheral view of the performance of leasing companies. Hence an indepth study is attempted to analyse the leasing industry in India, in all its manifestations

Molecular Epidemiology of Escherichia coli isolates from Environmental, Food and Clinical Sources

In the present study diversity of E. coli in the water samples of Cochin estuary were studied for a period of 3 years ranging from January 2010- December 2012. The stations were selected based on the closeness to satellite townships and waste input. Two of the stations (Chitoor and Thevara) were fixed upstream, two in the central part of the estuary namely Bolgatty and Off Marine Science Jetty, and one at the Barmouth. Diversity was assessed in terms of serotypes, phylogenetic groups and genotypes. Two groups of seafood samples such as fish and shellfish collected from the Cochin estuary were used for isolation of E. coli. One hundred clinical E. coli isolates were collected from one public health centre, one hospital and five medical labs in and around Cochin City, Kerala. From our results it was clear that pathogen cycling is occurring through food, water and clinical sources. Pathogen cycling through food is very common and fish and shellfish that harbour these strains might pose potential health risk to consumer. Estuarine environment is a melting pot for various kinds of wastes, both organic and inorganic. Mixing up of waste water from various sources such as domestic, industries, hospitals and sewage released into these water bodies resulting in the co-existence of E. coli from various sources thus offering a conducive environment for horizontal gene transfer. Opportunistic pathogens might acquire genes for drug resistance and virulence turning them to potential pathogens. Prevalence of ExPEC in the Cochin estuary, pose threat to people who use this water for fishing and recreation. Food chain also plays an important role in the transit of virulence genes from the environments to the human. Antibiotic resistant E. coli are widespread in estuarine water, seafood and clinical samples, for reasons well known such as indiscriminate use of antibiotics in animal production systems, aquaculture and human medicine. Since the waste water from these sources entering the estuary provides selection pressure to drug resistant mutants in the environment. It is high time that the authorities concerned should put systems in place for monitoring and enforcement to curb such activities. Microbial contamination can limit people’s enjoyment of coastal waters for contact recreation or shellfish-gathering. E. coli can make people sick if they are present in high levels in water used for contact recreation or shellfish gathering. When feeding, shellfish can filter large volumes of seawater, so any microorganisms present in the water become accumulated and concentrated in the shellfish flesh. If E. coli contaminated shellfish are consumed the impact to human health includes gastroenteritis, urinary tract infections (UTIs), and bacteraemia. In conclusion, the high prevalence of various pathogenic serotypes and phylogenetic groups, multidrug-resistance, and virulence factor genes detected among E. coli isolates from stations close to Cochin city is a matter of concern, since there is a large reservoir of antibiotic resistance genes and virulence traits within the community, and that the resistance genes and plasmid-encoded genes for virulence were easily transferable to other strains. Given the severity of the clinical manifestations of the disease in humans and the inability and/or the potential risks of antibiotic administration for treatment, it appears that the most direct and effective measure towards prevention of STEC and ExPEC infections in humans and ensuring public health may be considered as a priority.

Land Use Controls with Special Reference to Wetlands

This is a study of land use law in India. Land use Controls has been a subject of controversy since the human settlement. Gamut of control increased with human development. Now the controls are for many purposes.Nuisance created through various land use was tried to be avoidedthrough the common law controls7. Whether the utility of the activity outweighs the environmental consideration was the consideration before the court. A standard definition8 of nuisance could meet most of the problems relating to land use. Later on, planning and zoning laws brought in major changes. Health, safety and facilities of others attracted land use controls9. After the Stockholm the sphere of government interference increased. Several legislations were enacted. Existing legislations were modified. These come in conflict with the interests of different sections of society. Coastal Regulations10 and high range protection11 are manifestations of such unrest. A systematic study on these issues is of current interest. Exploring of some areas in this respect is also relevant in this respect.

Jugendliche Alltagsgestaltung und Identitätsbildung mit Fantasy-Rollenspielen - Schule öffnen für Elemente des Spiels und spielerische Aktionsformen

Gerade männliche Jugendliche nutzen in ihrer Pubertät und Adoleszenz zu einer gelingenden Gestaltung ihres Alltags und zur Ausbildung ihrer Identität zahlreiche Erscheinungsformen des Fantasy-Rollenspielens. In einem Prozess von Aneignung und Entäußerung integrieren dabei die Jugendlichen das überaus reiche multimediale Angebot, welches die Spiele bieten, in ihre Alltagsgestaltung, indem sie sich daraus spezifische Medien-, Text- und Ereignisarrangements bauen. Diese dienen einerseits der sozialen Integration und Distinktion, andererseits der Präsentation ihrer Identitätsentwürfe sich und anderen. Die Jugendlichen schaffen sich mittels dieser spezifischen Medien-, Text- und Ereignisarrangements eine in weiten Teilen von ihnen selbst bestimmte Welt, in der sie ihre Phantasie wie Kreativität mit großer Intensität, ja Obsession, innerhalb integrativer und solidarischer Interaktionsformen selbststeuernd und professionell ausleben. Diese Medien-, Text- und Ereignisarrangements zeigen Angebots- und Nutzungsformen, die sich nach einem medienkommunikativen Aneignungs- und Entäußerungsmodell in der Tradition der Cultural Studies (Stuart Hall) beschreiben lassen. Die Langzeitbeobachtung der Jugendlichen zeigt, dass sie alltagspragmatische Kulturtechniken zur selbstbestimmten Gestaltung von Alltag entwickeln: zunächst eine Strukturierung ihrer kognitiven, affektiven und pragmatischen Interaktion nach Kriterien erfolgreicher intrinsischer Interaktion, mit dem Ziel derer Perpetuierung im Flow-Erleben (Mihalyi Csikszentmihalyi), dann eine Ästhetisierung von Alltagswirklichkeit mittels kollektiver Fiktionalisierung in der Tradition des Collective Story Telling (Janet H. Murray). Diese Kulturtechniken stellen vor dem Hintergrund der Enkodierung und Dekodierung sozialer Codes spezifische Adaptionen von Prozessen der Bedeutungszuweisung und Subjekt- bzw. Identitätskonstitution dar. Die sie evozierenden und mit ihnen korrespondierenden handlungsleitenden Themen der Jugendlichen sind der Wunsch nach Rekonstitution von Gesamtheit in einer sich fragmentarisierenden Wirklichkeit, die Affirmation von Selbstbestimmung- und Autonomieerfahrungen, das Erleben von Reintegration und Solidarität für das sich dissoziiert erfahrende Individuum. Das Handeln der Jugendlichen basiert damit auf dem momentan dominanten Prozess einer Individualisierung von Lebenswelt unter den Bedingungen von Reflexivität und Erlebnisrationalität in der postmodernen Gesellschaft. Mit ihren Versuchen selbstbestimmter Gestaltung folgen sie dem aktuellen gesellschaftlichen Auftrag einer weitgehend in eigener Regie vorzunehmenden Lokalisierung dieses Prozesses. Zunehmend tritt diese von den Jugendlichen selbstgesteuerte Sozialisation neben die traditionell heteronome Sozialisation von gesellschaftlichen Instituten wie etwa die von Schule. Damit wird das Handeln der Jugendlichen zu einer Herausforderung an Pädagogik und Schule. Schule muss, wenn sie ihrem eigentlichen Auftrag von Förderung gerecht werden will, eine Sensibilität für diese Eigenständigkeit von Jugendlichen entwickeln und in der Beobachtung ihres Handelns didaktische Innovationen für Lehren und Lernen entwickeln. Im Mittelpunkt steht dabei die Wiederentdeckung des pädagogischen Dialogs, besonders aber die Entwicklung einer individualisierten Lernkultur und die Förderung jugendlicher Gestaltungskompetenzen, welche von deren alltagsästhetischen Erfahrungen und Kompetenzen im Umgang mit multimedialen Kulturprodukten ausgeht. Schule kann und muss für diese Prozesse selbstgesteuerten Lernens angemessene pädagogische Räume bereitstellen, in denen die Jugendlichen innerhalb eines geschützten Kontextes in der Auseinandersetzung mit eigenen wie fremden Entwürfen ihre Identität entwickeln können.

Gender and Space in Tehran

Abstract: This dissertation generally concentrates on the relationships between “gender” and “space” in the present time of urban life in capital city of Tehran. “Gender” as a changing social construct, differentiated within societies and through time, studied this time by investigation on “gender attitude” or “gender identity” means attitudes towards “gender” issues regarding Tehran residences. “Space” as a concept integrated from physical and social constituents investigated through focus on “spatial attitude” means attitudes towards using “living spaces” including private space of “house”, semi private semi public space of neighborhood and finally public spaces of the city. “Activities and practices” in space concentrated instead of “physical” space; this perspective to “space” discussed as the most justified implication of “space” in this debate regarding current situations in city of Tehran. Under a systematic approach, the interactions and interconnections between “gender” and “space” as two constituent variables of social organization investigated by focus on the different associations presented between different “gender identities” and their different “spatial identities”; in fact, “spatial identity” manifests “gender identity” and in opposite direction, “spatial identity” influences to construction of “gender identity”. The hypotheses of case study in Tehran defined as followed: • “Gender identity” is reflected on “spatial identity”. Various “gender identities” in Tehran present different perspectives of “space” or they identify “space” by different values. • As “gender identity” internalizes patriarchal oppression, it internalizes associated “spatial” oppression too. • Within the same social class, different “gender identities” related to men and women, present interconnected qualities, compared with “gender identities” related to men or women of different social classes. This situation could be found in the “spatial” perspectives of different groups of men and women too. • Following the upper hypotheses, “spatial” oppression differs among social classes of Tehran living in different parts of this city. This research undertook a qualitative study in Tehran by interviewing with different parents of both young daughter and son regarding their attitudes towards gender issues from one side and activities and behaviors of their children in different spaces from the other side. Results of case study indicated the parallel changes of parents’ attitudes towards “gender” and “spatial” issues; it means strong connection between “gender” and “space”. It revealed association of “equal” spatial attitudes with “open, neutral” gender attitudes, and also the association of “biased, unequal” spatial identities with “conservative patriarchal” gender identities. It was cleared too that this variable concept – gender space - changes by “sex”; mothers comparing fathers presented more equitable notions towards “gender spatial” issues. It changes too by “social class” and “educational level”, that means “gender spatial” identity getting more open equitable among more educated people of middle and upper classes. “Breadwinning status in the family” also presents its effect on the changes of “gender spatial” identity so participant breadwinners in the family expressed relatively more equitable notions comparing householders and housekeepers. And finally, “gender spatial” identity changes through “place” in the city and regarding South – North line of the city. The illustration of changes of “gender spatial” identity from “open” to “conservative” among society indicated not only vertical variation across social classes, furthermore the horizontal changing among each social class. These results also confirmed hypotheses while made precision on the third one regarding variable of sex. More investigations pointed to some inclusive spatial attitudes throughout society penetrated to different groups of “gender identities”, to “opens” as to “conservatives”, also to groups between them, by two opposite features; first kind, conservative biased spatial practices in favor of patriarchal gender relations and the second, progressive neutral actions in favor of equal gender relations. While the major reason for the inclusive conservative practices was referred to the social insecurity for women, the second neutral ones associated to more formal & safer spaces of the city. In conclusion, while both trends are associated deeply with the important issues of “sex” & “body” in patriarchal thoughts, still strong, they are the consequences of the transitional period of social change in macro level, and the challenges involved regarding interactions between social orders, between old system of patriarchy, the traditional biased “gender spatial” relations and the new one of equal relations. The case study drew an inhomogeneous illustration regarding gender spatial aspects of life in Tehran, the opposite groups of “open” and “conservative”, and the large group of “semi open semi conservative” between them. In macro perspective it presents contradicted social groups according their general life styles; they are the manifestations of challenging trends towards tradition and modernity in Iranian society. This illustration while presents unstable social situations, necessitates probing solutions for social integration; exploring the directions could make heterogeneous social groups close in the way they think and the form they live in spaces. Democratic approaches like participatory development planning might be helpful for the city in its way to more solidarity and sustainability regarding its social spatial – gender as well – development, in macro levels of social spatial planning and in micro levels of physical planning, in private space of house and in public spaces of the city.

Síndrome de pinzamiento femoroacetabular: manifestaciones clínicas y hallazgos por artroresonancia

El síndrome de pinzamiento femoroacetabular es una entidad reciente secundaria al “desacoplamiento” de la articulación coxofemoral, por alteración en la morfología de la cabeza femoral o del acetábulo, lo cual puede ocasionar osteoartrosis a temprana edad. El propósito del estudio es describir los signos clínicos más frecuentes y los hallazgos imagenológicos del síndrome de pinzamiento femoroacetabular. Metodologia: se realizó un estudio retrospectivo descriptivo de la frecuencia de las manifestaciones clínicas del síndrome de pinzamiento femoroacetabular y hallazgos en artroresonancia magnética entre los meses de Enero de 2008 a junio de 2009. Se seleccionaron treinta y dos pacientes en la institución, y se evaluaron sus manifestaciones clínicas, examen físico e imágenes de artroresonancia magnética. Resultados: todos los pacientes presentaron dolor inguinal en el momento de la consulta, con presencia de test de pinzamiento positivo para todos, y el signo de la C en el 90%. El subtipo más frecuente fue PINCER 46.6 % seguido por el pinzamiento MIXTO 39.3%. El signo de crossover estuvo presente en el 100% de los pacientes con retroversión acetabular (12). El resultado de incapacidad funcional fue WOMAC 48.44 ±14.79 (IC 95% 43.1-53.77), nunca fue mayor a 50 y el dolor tuvo un promedio de 11 / 20. Discusión: la artroresonancia magnética es el examen de elección, cuyos hallazgos permiten comprender las manifestaciones clínicas. El ángulo alfa y la versión femoral constituyeron los signos más significativos, estos hallazgos son equiparables a los obtenidos en estudios donde la mayor parte de la población son mujeres de edad media.

Análisis de las implicaciones del accionar terrorista, en las iniciativas de contraterrorismo de la Unión Europea, después del 11 de septiembre de 2001 hasta 2008, a la luz de los conceptos de la Geopolítica contemporánea. Estudio de caso: Estrategias de España y Francia frente a ETA

A lo largo de la historia el terrorismo con sus diversas manifestaciones ha llevado a que éste se convierta en un factor común, sin dejar de ser complejo, en los escenarios geográficos en los que el fenómeno se ha venido desarrollando. Pensamientos variados y cambiantes han permitido que el terrorismo adquiera diferentes matices dependiendo de la época, el territorio y la población directa a la cual se enfrenta y por supuesto a las Instituciones y demás regiones y habitantes de las mismas que resultan afectadas por su impacto. En este trabajo se consideran datos importantes de ETA (Euskadi Ta Askatasuna) para el análisis ya que ha sido desde su nacimiento uno de los principales factores que han desestabilizado las relaciones geopolíticas de los países implicados en el tema.

La incidencia del conflicto armado durante el primer mandato del presidente Uribe en las relaciones de seguridad fronteriza con Venezuela y Ecuador

Esta investigación busca analizar el proceso de internacionalización del conflicto armado en Colombia, teniendo en cuenta que durante casi cincuenta años pasó desapercibido e incluso indiferente, tanto a nivel doméstico como por el sistema internacional. De igual manera, el objetivo general de este análisis es evaluar las consecuencias del conflicto armado en Colombia en las relaciones de seguridad fronteriza durante el periodo del 2002-2006; a partir de esto, se plantean cuatro propósitos principales. Primero, describir el proceso de internacionalización del conflicto, entendiendo que su incidencia en la zona se ha desarrollado desde el concepto del efecto derrame. Segundo, establecer si existe alguna diferencia sobre la incidencia del conflicto en los diferentes puntos de frontera y determinar por qué es diferente la situación en los puntos de frontera para Venezuela y Ecuador. Para ello, se analizarán las manifestaciones del conflicto que han incidido en las relaciones con Venezuela, y a partir de esto establecer sus repercusiones; de la misma forma, se examinaran las manifestaciones que han incidido del lado ecuatoriano. Tercero, se buscará establecer de qué manera es similar o diferente la incidencia del conflicto armado colombiano con respecto a cada frontera de estudio y determinar sus repercusiones en las relaciones sobre la seguridad fronteriza. Cuarto, se pretende evaluar la posibilidad de un acercamiento por parte de los tres países en aras de buscar un beneficio común, adoptando un régimen de seguridad colectiva o de intereses compartidos que permitan combatir en conjunto la seguridad en los puntos de frontera, que finalmente es la causa que distorsiona las relaciones.

La arte-terapia como camino de transformación espiritual

Desde el abordaje de la arte-terapia y de la espiritualidad, es posible hallar la relación que ambos conceptos entrañan, relacionado con el significado simbólico y universal que el arte (a través de todas su manifestaciones), puede brindar al espíritu para alcanzar su transformación (personal y transpersonal), sea ésta comprendida desde un marco de intervención en patología o en disfuncionalidad, así como desde el marco de promoción en salud, teniendo en cuenta el carácter holístico de todo ser humano. ¿Qué tiene el arte que "cura" a los pacientes? Mediante una revisión de la literatura que tiene en cuenta las características específicas de la intersección de estos dos campos, tales como la relación terapéutica, el acto creativo, los niveles transpersonales del desarrollo y la imaginación, se aborda este interrogante.
