Psychodrame et démence : accompagnement de l'oubli sidératif par le corps et le geste
Authors: Maurin Mélanie , Gimenez Guy
Published: November 2011

Résumé Dans nos institutions, le nombre de patients présentant des symptomatologies démentielles ne cesse de grandir. Face à une symptomatologie pour laquelle le modèle de compréhension de référence reste celui de la neuro-cognition, nous souhaitons ouvrir le champ de la démence à celui de la psychanalyse de groupe. Nous pratiquons ainsi le psychodrame psychanalytique de groupe avec des patients déments, dispositif que nous aménageons en fonction des spécificités de cette population. Dans ce travail, nous portons une attention particulière au symptôme de l’oubli démentiel que nous qualifions de sidératif du fait de ses modalités d’émergence, et du vécu qu’il convoque pour les protagonistes en présence. Notre objectif est de repérer comment il est possible de réaccéder à des traces psychiques, en apparence inaccessibles, en passant par le corps, l’affect et la motricité. Nous faisons l’hypothèse qu’au-delà d’une étiologie organique, il y aurait une dimension psychique aux conditions et manifestations de l’oubli chez les patients déments. Nous observons que la dynamique groupale peut favoriser une relance du souvenir. Pour cela, le clinicien se doit de développer des techniques qui passent par le sensoriel, la corporéité pour préfigurer une forme qui était déjà là auparavant mais qui semble être attaquée au point de disparaître psychiquement, comme effacée.

Authors: Schwarzkopf Ruth , Sherman Rose O. , Kiger Anna J.
Published: November 2011

The recent Institute of Medicine (
2010
) report,
The Future of Nursing: Leading Change, Advancing Health,
included a recommendation that nurses at all levels should be prepared and enabled to lead change to advance health care in the United States. Historically, in most organizations, nursing leadership development programs have focused on nurses in management or executive roles rather than those working in front-line leadership roles. This article describes a front-line leadership development initiative developed by Tenet Healthcare Corporation and attended by 400 charge nurses. Program development, evaluation, and lessons learned that can be applied in other organizations are discussed.

Authors: Kekunnaya Ramesh , Gupta Amit , Sachdeva Virender , Krishnaiah Sannapaneni , Venkateshwar Rao B. , Vashist Urvish , Ray Debajit
Published: November 2011

Purpose:

To determine the demographic and clinical profile of various subtypes of Duane retraction syndrome (DRS).

Methods:

Retrospective case series of 441 patients.

Results:

Of the total 441 patients, 389 (88.2%) and 52 (11.8%) patients had unilateral and bilateral involvement, respectively. In both unilateral and bilateral cases, type I was the most common subtype, followed by types III and II. Mean age of presentation of type I DRS was significantly less (13.3 years) compared with types II (23 years) and III (21.9 years) (
P
< .05). Unilateral disease was significantly more common in females (57. 6%,
P
= .006), whereas there was no gender predilection in bilateral cases (
P
= .77). Type 1 DRS was significantly more common among females (57.96%,
P
= .003) compared with males, whereas there was no such gender predilection in types II and III. The left eye was more commonly involved in patients with types I and III (
P
< .05), whereas in type II there was no such predilection for any eye involvement. Esotropia was more common in patients with bilateral disease (53.8%) and exotropia was predominant ocular deviation in patients with types II and III (70% and 66.67%,
P
= .03). There was no difference in the type of deviation in patients with type I (
P
> .05). Upshoots and downshoots were more common in unilateral disease and types I and III compared with type II.

Conclusion:

Unilateral and bilateral DRS show considerable differences in gender distribution, associated ocular deviation, overshoots, and ocular and systemic associations.

An Experience Using Performance-Centered Mobile Learning to Enhance Fieldwork Education
Authors: Stoyanova-Petrova Silviya
Published: November 2011

Mobile performance support system (mPSS) focuses on helping students to perform an authentic task with minimum support of others, providing them with sufficient information such as expert advice and procedures, just-in-time. Providing this support on a mobile device enables students to make their learning more efficient and relevant. Fieldwork has long been identified as providing students undertaking professional studies with a means of implementing theory into real life situations. In many ways there is a natural link between fieldwork and mobile technology. This paper reports our experience using performance-centered mobile learning to enhance active, fieldwork education and the investigation of its impact on students learning. Fieldwork education is vital for many engineering courses. Two case studies held outside the classroom are presented. In the first case, the students are admitted to the technical equipment in a base station of a Bulgarian mobile operator outside the city of Plovdiv. In the second case, students visit an electronics manufacturing plant and directly inspect the production process.
La participation en science à l’ère des enjeux globaux
Authors: Schiele Bernard
Published: November 2011

Résumé Pour penser la participation dans le monde globalisé d’aujourd’hui quatre dimensions au moins doivent être prises en compte : la conscience de l’environnement, l’impact des techno-sciences sur la société, la poussée de la communication, et l’impératif économique. Planétaires, elles sont partout à l’œuvre. Chacune importe moins que l’ensemble de leurs interactions croisées. Elles ont entraîné une transformation des modes de production du savoir, de sa mise en circulation, de son appropriation, et des modalités de sa mobilisation. Cette évolution se traduit par une ambivalence du public par rapport aux sciences. Ce qui oblige à une reconsidération de la conception de la participation des acteurs sociaux dans les situations où différents rapports au savoir sont mobilisés afin de tenir compte des différents expériences, perspectives et intérêts des groupes impliqués.
Nicolas Sarkozy : des vœux en continuité pour le candidat de la rupture
Authors: Finniss-Boursin Françoise
Published: November 2011

Résumé À l’heure où l’évidence des changements qui affectent le champ de la communication politique (l’exhibition de certains moments de la vie privée, la médiatisation de l’individu sous les habits institutionnels) pourrait inciter à laisser pour compte les persistances, Françoise Finniss-Boursin, qui a analysé tous les discours de vœux des Présidents français depuis 1958, s’intéresse aux vœux télévisés du Président Nicolas Sarkozy (2007-2009). Comment l’autoproclamé candidat de la « rupture » allait-il aborder cet exercice ? Au-delà de l’éclairage sur le décalage entre promesses et mises en pratique de l’actuel président, Françoise Finniss-Boursin engage une réflexion sur le rôle du rite et de la solennité dans la construction d’un représentant politique. Ce n’est pas parce que la politique est l’affaire de tous et que le politique se dissémine aujourd’hui partout que ne persistent pas des lieux où se construit la figure politique.
The psychometric relationship between career thinking and salutogenic functioning amongst unemployed adults
Authors: Austin Kirk , Cilliers Frans
Published: November 2011

Orientation: Corporate survival mechanisms, like mergers, downsizing, restructuring and outsourcing, contribute to unemployment levels amongst adults. Psychological maturity seems to influence the quality of the career decisions that people make in these difficult circumstances. However, we do not know what their behavioural strengths are.Research objectives: The objective of this study was to investigate the psychometric relationship between career thinking (negative and positive career thoughts) and salutogenic functioning (locus of control and sense of coherence) amongst unemployed adults.Motivation for study: Career decision research has consistently surveyed students to understand career indecision. Adults are not a homogenous group. Therefore, this trend may not reflect throughout the larger adult population. For this reason, the researchers conducted exploratory research into the nature of career indecision amongst non-student adults.Research design, approach and method: The researchers used a quantitative design that included a four-instrument survey on a purposive sample of 225 Canadian unemployed and non-student adults who had not decided on a career. They calculated correlations and regressions.Main findings: The researchers reported significant relationships between the four constructs. They found that a sense of coherence predicted career thinking.Contribution/value-add: A sense of coherence, which includes comprehension, meaningfulness and manageability, acts as a facilitator of effective career thinking.Practical/managerial implications: During career assessment and guidance, the role of sense of coherence as a strength factor will indicate the person’s readiness to make important career decisions.
The CU ground MAX-DOAS instrument: characterization of RMS noise limitations and first measurements near Pensacola, FL of BrO, IO, and CHOCHO
Authors: Coburn S. , Dix B. , Sinreich R. , Volkamer R.
Published: November 2011

Abstract. We designed and assembled the University of Colorado Ground Multi AXis Differential Optical Absorption Spectroscopy (CU GMAX-DOAS) instrument to retrieve bromine oxide (BrO), iodine oxide (IO), formaldehyde (HCHO), glyoxal (CHOCHO), nitrogen dioxide (NO2) and the oxygen dimer (O4) in the coastal atmosphere of the Gulf of Mexico. The detection sensitivity of DOAS measurements is proportional to the root mean square (RMS) of the residual spectrum that remains after all absorbers have been subtracted. Here we describe the CU GMAX-DOAS instrument and demonstrate that the hardware is capable of attaining RMS of ∼6 × 10−6 from solar stray light noise tests using high photon count spectra (compatible within a factor of two with photon shot noise). Laboratory tests revealed two critical instrument properties that, in practice, can limit the RMS: (1) detector non-linearity noise, RMSNLin, and (2) temperature fluctuations that cause variations in optical resolution (full width at half the maximum, FWHM, of atomic emission lines) and give rise to optical resolution noise, RMSFWHM. The non-linearity of our detector is low (∼10−2) yet – unless actively controlled – is sufficiently large to create RMSNLin of up to 2 × 10−4. The optical resolution is sensitive to temperature changes (0.03 detector pixels °C−1 at 334 nm), and temperature variations of 0.1°C can cause RMSFWHM of ~1 × 10−4. Both factors were actively addressed in the design of the CU GMAX-DOAS instrument. With an integration time of 60 s the instrument can reach RMS noise of 3 × 10−5, and typical RMS in field measurements ranged from 6 × 10−5 to 1.4 × 10−4. The CU GMAX-DOAS was set up at a coastal site near Pensacola, Florida, where we detected BrO, IO and CHOCHO in the marine boundary layer (MBL), with daytime average tropospheric vertical column densities (average of data above the detection limit), VCDs, of ∼2 × 1013 molec cm−2, 8 × 1012 molec cm−2 and 4 × 1014 molec cm−2, respectively. HCHO and NO2 were also detected with typical MBL VCDs of 1 × 1016 and 3 × 1015 molec cm−2. These are the first measurements of BrO, IO and CHOCHO over the Gulf of Mexico. The atmospheric implications of these observations for elevated mercury wet deposition rates in this area are briefly discussed. The CU GMAX-DOAS has great potential to investigate RMS-limited problems, like the abundance and variability of trace gases in the MBL and possibly the free troposphere (FT).
Changing climatic and anthropogenic influences on the Bermejo wetland, through archival documents – Mendoza, Argentina, 16th–20th centuries
Authors: Prieto M. R. , Rojas F.
Published: November 2011

Abstract. The wrong management of watering in the highest zones of the Mendoza northern oasis, the topography of the terrain and the deficient drainage, together with neotectonics phenomena, but mostly a dramatic and progressive increase of the Rio Mendoza flow volume originated the expansion of the wetlands area at the NE of the city of Mendoza at the turn of the 18th century, while in previous centuries it had retracted to a minimum. The area grew until reaching the dimension of large wetlands in the lowest oasis zones, resulting from a larger runoff and soil saturation by the rise of the phreatic layers. This situation remained throughout the 19th century, affecting the extension and use of the available land for human activity. The purpose of this study was to research this process that culminated in 1930 with the partial desiccation of the area. We have given particular importance to the influence of the climatic fluctuations in the Cordillera de los Andes and to the consequent variations of the Rio Mendoza flow volume in this process. For the analysis we used snowfall series at the cordillera and flow volume of the Rio Mendoza, built by Prieto (2009) with documental data. We analyzed which were the mediate and immediate consequences of the growth and later desiccation of the wetlands over the environment and its present repercussion on the ecosystem (salinization, poor soil drainage, soil alkalinization, sedimentation). In addition, we have also worked over georeferenced historic charts that partially reflect the behavior of the Cienaga del Bermejo during the 18th, 19th and 20th centuries. This behavior characterized by "growth pulses" and retraction moments is reflected in the analyzed charts, where those moments of major growth coincide with cycles of bigger snowstorms and larger flow volume in the Rio Mendoza.

Authors: Barreto Marcia Regina
Published: November 2011

O presente estudo teve como objetivo geral analisar o potencial ecoturístico do Parque Governador José Rollemberg Leite que se localiza dentro da Área de Proteção Ambiental Morro do Urubu em Aracaju, Estado de Sergipe. Para isso foi necessário fazer um diagnóstico dos atrativos turísticos potenciais para o desenvolvimento do ecoturismo no parque, bem como traçar o perfil da comunidade local e propor ações necessárias para a implantação do Ecoturismo no Parque. A metodologia utilizada foi a descritivo-exploratória e os procedimentos técnicos foram pesquisa bibliográfica e documental, diagnóstico, coleta de dados e entrevista. A comunidade local foi analisada de forma relevante neste trabalho visto que para o desenvolvimento ecoturístico de um lugar a consulta comunitária é um item imprescindível. De acordo com os dados coletados sobre a comunidade observou-se que 36% da comunidade é composta por jovens de 19 a 25 anos, o grau de escolaridade de maior incidência foi o ensino fundamental e o médio, 36% e 50% respectivamente, quanto à principal ocupação a maioria dos entrevistados são autônomos, 26%, verificou-se também que 68% da comunidade reside no bairro a mais de dez anos e a importância do parque na visão da comunidade é o lazer, 70%, além disso, foi possível observar que 34% da comunidade desenvolve alguma atividade artesanal. Uma análise sobre sustentabilidade e gestão permitiu traçar um conjunto de problemas detectados no parque e a partir daí foram propostas soluções. Quanto aos equipamentos, infraestrutura e serviços turísticos em funcionamento no parque foram identificados o teleférico, o mirante, o parque infantil, o zoológico e o Centro de Equoterapia de Sergipe. O parque apresenta potencial para o desenvolvimento de algumas atividades compatíveis com o meio natural que são: cicloturismo, estudo do meio, Hikking (caminhada de curta duração), observação da fauna e flora e safári fotográfico. A partir dos resultados obtidos foi possível considerar o ecoturismo viável para o parque sob o aspecto da sustentabilidade em âmbito econômico, ecológico e ambiental.

Published: November 2011

A interpretação ambiental tem sido um grande aliada do ecoturismo em Unidades de Conservação, traduzindo para a linguagem dos visitantes as informações a respeito dos recursos recreacionais. Para tal, ela necessita ser: temática, organizada, significativa, diferenciada e provocante. Nesse sentido, buscou-se valorizar os recursos ambientais da Trilha do Chapadão, Parque Nacional do Catimbau, Buíque, Estado de Pernambuco, de forma a levar os visitantes a interagirem mais intimamente com a natureza, dando-lhe importância em relação à sua conservação. Assim, o trabalho teve como objetivo analisar o potencial interpretativo da trilha, afim de enriquecer as atividades desenvolvidas pelos condutores de turismo local. Para alcançar o objetivo foi realizada revisão bibliográfica, buscando relações com estudos de casos. A partir disso, realizou-se visitas in loco, quando foram levantados os pontos de potencial interpretativo. O Parque Nacional do Catimbau fica localizado na zona de transição entre o agreste e sertão pernambucano, a 285 km do Recife, capital do Estado. O Parque possui 09 trilhas oficiais, sendo uma de longo percurso. Dentre estas trilhas, foi selecionada a do Chapadão, uma vez que possui uma diversidade de recursos que permitem oferecer riqueza de informações aos visitantes. A trilha possui extensão de 3.244 metros e não possui nenhum tipo de sinalização. Notou-se que, em relação à vegetação, existem diferentes composições, sendo que num primeiro trecho é possível encontrar muitas espécies da caatinga, como facheiro, caxacubri, coroa-de-frade, quipá etc. Num outro trecho, a vegetação é mais semelhante a um Cerradão, com vegetação um pouco mais densa, mas ainda bastante seca. Além da exuberância da vegetação, a trilha é marcada por formações areníticas de grande beleza e por um painel de pinturas rupestres de tradição nordeste, chamado de “Homens sem Cabeça”. Os vários mirantes da trilha permitem visão privilegiada do Chapadão que dá nome à trilha, sendo que de um deles avista-se um dos maiores atrativos da trilha, a Boca do Leão, formação que se assemelha ao animal de boca aberta. Esse mirante permite ainda a contemplação da paisagem composta por parte do cânion e abaixo o Brejo de São José. Considerando todos esses diferentes atrativos, é possível afirmar que a trilha possui grande potencial interpretativo, que pode ser desenvolvido tanto através dos condutores locais como através de recursos como painéis, placas e folheteria. Desta forma, a experiência do visitante poderá ser maximizada ao mesmo tempo em que se justifica a importância da conservação da área.
Influence of discipline of provider and model of care on an arthritis educational intervention in primary care
Authors: Lineker Sydney C. , Husted Janice A. , Brown K. Stephen
Published: November 2011

Objective

To identify both provider and organizational characteristics that predicted outcomes following an educational intervention (9‐hour workshop and followup reinforcement activities) developed to improve the management of arthritis in primary care.

Methods

Providers completed a survey at baseline and at 6 months postworkshop, including a case scenario for early rheumatoid arthritis. Providers were asked how they would manage the case and their responses were coded to calculate a best practice score, ranging from 0–7. Two‐level hierarchical linear modeling was used to determine which of the measured provider and organizational factors predicted best practice scores at followup.

Results

A total of 275 multidisciplinary providers from 131 organizations completed both baseline and followup surveys. Best practice scores increased by 17% (P < 0.01); however, the mean score at 6‐month followup remained relatively low (2.68). Significant predictors of best practice scores at followup were discipline of provider and model of primary care in which they worked (P < 0.05), adjusting for baseline practice scores and clustering of providers within organizations. Physicians, nurse practitioners, and rehabilitation therapists scored higher than nurses, students, and other health care providers (P < 0.01). Physician networks scored significantly lower than providers from multidisciplinary‐oriented models of care (P = 0.02).

Conclusion

These results have implications for the education of health professionals and the design of models of care to enhance arthritis care delivery.

Published: November 2011

Objective

To use consensus methods and the considerable expertise contained within the Childhood Arthritis and Rheumatology Research Alliance (CARRA) organization to extend the 3 previously developed treatment plans for moderate juvenile dermatomyositis (DM) to span the full course of treatment.

Methods

A consensus meeting was held in Chicago on April 23–24, 2010, involving 30 pediatric rheumatologists and 4 lay participants. Nominal group technique was used to achieve consensus on treatment plans that represented typical management of moderate juvenile DM. A preconference survey of CARRA, completed by 151 (56%) of 272 members, was used to provide additional guidance to the discussion.

Results

Consensus was reached on timing and rate of steroid tapering, duration of steroid therapy, and actions to be taken if patients were unchanged, worsening, or experiencing medication side effects or disease complications. Of particular importance, a single consensus steroid taper was developed.

Conclusion

We were able to develop consensus treatment plans that describe therapy for moderate juvenile DM throughout the treatment course. These treatment plans can now be used clinically, and data collected prospectively regarding treatment effectiveness and toxicity. This will allow comparison of these treatment plans and facilitate the development of evidence‐based treatment recommendations for moderate juvenile DM.
Stereoselective inhibitory effect of flurbiprofen, ibuprofen and naproxen on human organic anion transporters hOAT1 and hOAT3
Authors: Honjo Hiroaki , Uwai Yuichi , Aoki Youhei , Iwamoto Kikuo
Published: November 2011

Nonsteroidal anti‐inflammatory drugs (NSAIDs) delay the renal excretion of antifolate methotrexate by inhibiting human organic anion transporters hOAT1 (SLC22A6) and hOAT3 (SLC22A8). In this study, uptake experiments were performed using Xenopus laevis oocytes to assess stereoselectivity in the inhibitory characteristics of flurbiprofen, ibuprofen and naproxen against hOAT1 and hOAT3. Uptake of p‐aminohippurate by hOAT1 was inhibited by each enantiomer of the three NSAIDs, and the inhibitory effect was superior in each (S)‐enantiomer around 10 µ m. The apparent 50% inhibitory concentrations were estimated to be 0.615 µ m for (S)‐flurbiprofen, 2.84 µ m for (S)‐ibuprofen and 1.93 µ m for (S)‐naproxen, and these values were significantly lower than those of the respective (R)‐enantiomers [(R)‐flurbiprofen: 2.35 µ m, (R)‐ibuprofen: 6.14 µ m, (R)‐naproxen: 5.26 µ m]. Furthermore, the (S)‐NSAIDs at 3 µ m reduced methotrexate accumulation in hOAT1‐expressing oocytes more strongly than the corresponding (R)‐enantiomers. All enantiomers inhibited hOAT3‐mediated transport of estrone sulfate and methotrexate, but there was no difference between both enantiomers of each NSAID in the inhibitory potencies. Eadie‐Hofstee plot analysis showed that (S)‐flurbiprofen and (R)‐flurbiprofen inhibited hOAT1 and hOAT3 in a competitive manner. These findings represent the stereoselective inhibitory potencies of flurbiprofen, ibuprofen and naproxen on hOAT1, and the (S)‐enantiomers are greater. In contrast, stereoselectivity was not recognized in their inhibitory effect on hOAT3. Copyright © 2011 John Wiley & Sons, Ltd.

Artificial neural network in diagnosis of metastatic carcinoma in effusion cytology
Authors: Barwad Adarsh , Dey Pranab , Susheilia Shaily
Published: November 2011

Aims and objectives:

To build an artificial neural network (ANN) model for the detection of carcinoma in effusion cytology.

Materials and methods:

We selected a total of 114 effusion cytology cases consisting of 57 each benign and malignant case. In all these cases, detailed cytological features, image morphometric data, densitometric data, and chromatin textural data were collected. Based on these data, we made a back propagation ANN model for diagnosing malignancy in effusion cytology. This network was designed as 25‐2‐1 (input nodes‐hidden nodes‐output node). Online back propagation method was applied for training the network. The training of the network was continued until the network error was reduced to 0.000654. Simultaneously, we also performed logistic regression (LR) analysis test to compare with ANN model performance.

Result:

ANN model worked excellent after adequate training. With the help of this model, it was possible to identify correctly all the malignant cases in validation and test set. The result of the multivariate LR analysis was also similar as that of ANN model and all the cases were also classified correctly.

Conclusions:

In this study, we successfully constructed an ANN model to diagnose metastatic carcinoma in effusion cytology. ANN is very promising in the diagnosis of metastatic carcinoma in effusion cytology. In future, ANN model may help the cytopathologist to diagnose the difficult cases in effusion fluid. © 2011 International Clinical Cytometry Society
Range‐wide genetic population structure of common pochard (Aythya ferina): a potentially important vector of highly pathogenic avian influenza viruses
Authors: Liu Yang , Keller Irene , Heckel Gerald
Published: November 2011

An understanding of the distribution and spatial structure of the natural vectors of zoonothic pathogens is of interest for effective disease control and prevention. Here, we investigate the range‐wide population genetic structure of common pochard (Aythya ferina), a long‐distance migratory duck and potential vector of highly pathogenic avian influenza. We collected several hundred samples from breeding and wintering grounds across Eurasia including some H5N1‐positive individuals and generated partial sequences of the mitochondrial control region and multilocus microsatellite genotypes. Genetic differentiation among breeding populations was significant for both marker types but higher for maternally inherited mtDNA than for biparentally inherited nuclear markers. There was only weak genetic divergence between ducks sampled in Europe and East Asia, and genetic differentiation between populations was not generally associated with geographical distance. No evidence of genetic substructure was detected for ducks sampled on the European wintering grounds. Our results suggest limited breeding‐site fidelity, especially in females, but extensive population admixture on the wintering grounds. The specific role of pochards as natural vectors of zoonotic pathogens and in particular H5N1 remains to be clarified but our results point to wintering grounds as potential hotspots for disease transmission.
