Assessing the quality of classification models: Performance measures and evaluation procedures
Authors: Cichosz Paweł
Published: June 2011

This article systematically reviews techniques used for the evaluation of classification models and provides guidelines for their proper application. This includes performance measures assessing the model’s performance on a particular dataset and evaluation procedures applying the former to appropriately selected data subsets to produce estimates of their expected values on new data. Their common purpose is to assess model generalization capabilities, which are crucial for judging the applicability and usefulness of both classification and any other data mining models. The review presented in this article is expected to be sufficiently in-depth and complete for most practical needs, while remaining clear and easy to follow with little prior knowledge. Issues that receive special attention include incorporating instance weights to performance measures, combining the same set of evaluation procedures with arbitrary performance measures, and avoiding pitfalls related to separating data subsets used for evaluation from those used for model creation. With the classification task unquestionably being one of the central data mining tasks and the vastly increasing number of data mining applications — not only in business, but also in engineering and research — this is expected to be interesting and useful for a wide audience. All presented techniques are accompanied by simple R language implementations and usage examples, which — whereas created to serve the illustration purpose mostly — can be actually used in practice.
High-Harmonic Spectroscopy: From Femtosecond to Attosecond Molecular Dynamics
Authors: Wörner Hans Jakob
Published: June 2011

The principles of high-harmonic spectroscopy (HHS) are illustrated using two recent examples from the literature. The method can be applied as a probe to measure the evolution of the electronic structure of a molecule during a chemical reaction on the femtosecond time scale. Alternatively,
it can be used as a comprehensive method unifying pump and probe steps into a single laser cycle to measure electronic dynamics on the at to second time scale.
Computational Spectroscopy and Reaction Dynamics

Published: June 2011

Physico- and bio-chemical processes on the femto- to picosecond time scale are ideally suited to be investigated with all-atom simulations. They include, amongst others, vibrational relaxation, ligand migration in sterically demanding environments (proteins, ices), or vibrational spectra.
By comparing with experimental data, the results can be used to obtain an understanding of the mechanisms underlying the observations. Furthermore, most of these processes are sensitive to the intermolecular interactions. Therefore, detailed refinement of such interaction potentials
is possible.

'Indigenising' or 'interculturalising' universities in Mexico?: Towards an ethnography of diversity discourses and practices inside the Universidad Veracruzana Intercultural
Authors: Dietz Gunther , Cortés Laura Mateos
Published: June 2011

Multicultural discourse has reached Latin American higher education in the form of a set of policies targeting indigenous peoples. These policies are strongly influenced by the transfer of European notions of 'interculturality', which, in the Mexican context, are understood as positive interactions between members of minority and majority cultures. In Mexico, innovative and often polemical 'intercultural universities or colleges' are being created by governments, by NGOs or by pre-existing universities. This trend towards 'diversifying' the ethnocultural profiles of students and curricular contents coincides with a broader tendency to force institutions of higher education to become more 'efficient', 'corporate' and 'outcome-oriented'. Accordingly, these still very recently established 'intercultural universities' are often criticised as being part of a common policy of 'privatisation' and 'neoliberalisation' and of developing curricula particular to specific groups which weakens the universalist and comprehensive nature of Latin American public universities. Indigenous leaders, on the contrary, frequently claim and celebrate the appearance of these new higher education opportunities as part of a strategy of empowering actors of indigenous origin or African descent.

Going beyond this polemic, this paper presents the first findings of an activist anthropological and ethnographically-based case study of the actors participating in the configuration of one of these new institutions of higher education, the Universidad Veracruzana Intercultural (UVI), located on the Mexican gulf coast. This article examines the way UVI has appropriated the discourse of interculturality on the basis of fieldwork conducted in the four indigenous regions where the UVI offers a B.A. in Intercultural Management for Development. The study focuses on the actors' teaching and learning practices, which are strongly shaped by an innovative and hybrid mixture of conventional university teaching, community-oriented research and 'employability'-driven development projects.

Published: June 2011

Résumé À travers le récit du suivi psychothérapique de Sandrine, une jeune adolescente à l’histoire marquée par de nombreuses ruptures, les cliniques de la colère, des troubles du comportement, de la boulimie sont examinés sous l’angle de la capacité progressive de mentalisation. Penser son histoire, supporter la relation transférentielle à son thérapeute, deux axes pour envisager les allers-retours vers la position dépressive de la théorie kleinienne. La position dépressive est mise en relation avec la notion de mal-être, compris par l’auteur comme un « en deçà » psychique de la dépression, un « hors psychique ».
Manifestation conversive pour clore l'âge de latence
Authors: de Becker Emmanuel
Published: June 2011

Résumé L’intérêt des professionnels de la santé mentale pour les manifestations hystériques n’a jamais faibli, que ce soit pour lui donner un statut à part entière, pour la réduire à une attitude de simulation ou tenter d’en comprendre les mécanismes étiopathogéniques. L’article développe une situation clinique d’une jeune à l’aube de l’adolescence, présentant une amnésie qualifiée de psychogène. Devant un tel tableau, la prudence s’impose ; en effet, les symptômes faisant évoquer des troubles de nature hystérique chez l’enfant nécessitent une évaluation avec diagnostic différentiel incluant les volets physique et psychique, ce qui justifie pleinement une approche pédiatrique et pédopsychiatrique conjointe. L’auteur, après avoir repris quelques considérations psychopathologiques sur le concept d’hystérie, propose de discuter des significations possibles de la manifestation conversive. Parmi les hypothèses, on peut retenir celle qui consiste à comprendre l’apparition du trouble comme modalité pour clore l’âge de latence.
Osteoporosis Treatment: An Evidence-Based Approach
Authors: Ragucci Kelly R. , Shrader Sarah P.
Published: June 2011

Osteoporosis is a disease that results in decreased bone mass and quality of bone, which may lead to fracture. Clinicians need to counsel individuals on appropriate intake of calcium and vitamin D, increasing weight-bearing exercise, limiting alcohol and caffeine, and avoiding smoking. A variety of nonhormonal pharmacological options are available for prevention and treatment of osteoporosis, including bisphosphonates, calcitonin (Miacalcin®), raloxifene (Evista®), teriparatide (Forteo®), and denosumab (Prolia®). The National Osteoporosis Foundation and the American Association of Clinical Endocrinologists have recently published new guidelines, and it is important for clinicians to be familiar with the evidence behind each of these treatment modalities. It is paramount for nurses to make evidence-based, cost-effective decisions about pharmacological therapy based on individual patient-specific factors.
Bilateral Unstable Slipped Capital Femoral Epiphysis: A Look at Risk Factors
Authors: Herrera-Soto José A. , VanderHave Kelly L. , Gordon Eric , Fabregas Jorge , Phillips Jonathan H. , Schoenecker Perry , Parsch Klaus
Published: June 2011

Unstable slipped capital femoral epiphysis can have disastrous complications including osteonecrosis and chondrolysis. It has been shown that 20% to 80% of patients may develop a contralateral slip ≤18 months after diagnosis. The purpose of this article is to report and characterize patients who developed bilateral unstable slips. After Institutional Review Board approval, the patients included were only those with bilateral unstable slipped capital femoral epiphyses. A minimum 2-year follow-up was required. Seven patients, all female, were included in the study, with an average age of 11.4 years at the time of their first slips. The interval between slips averaged 127 days (range, 0–245 days). All but 1 patient presented with a severe slip. The second slip was also severe in 3 patients and less severe in 4 patients. The triradiate cartilage was open in 3 patients. Two patients required corrective osteotomies. Chondrolysis developed in 2 patients with no osteonecrosis reported. The incidence of bilateral unstable slips ranged from 4% to 20% of all unstable slipped capital femoral epiphyses based on our findings. Skeletal immaturity was not a risk factor. The surgeon must be vigilant for the possibility of bilateral slips. The family must be instructed on precautions patients must take while recuperating from unstable slipped capital femoral epiphyses. Contralateral fixation of the unaffected side may be warranted in patients with initial severe unstable slipped capital femoral epiphyses to prevent this condition.

Published: June 2011

The treatment of distal tibial fractures with anterior soft tissue injury is relatively difficult. The aim of this study was to explore the efficacy and safety of the posteromedial anatomical plate for such fractures. Between February 2006 and January 2009, twenty-six cases of distal tibial fracture with anterior soft tissue injury were treated with posteromedial anatomical plates designed by our traumatic orthopedic center. Of the 26 cases, 12 were open fractures (4 Gustilo-Anderson type I, 5 type II, 2 type IIIA, and 1 type IIIB), and 14 were closed fractures (3 Tscherne-Oestern type I, 9 type II, 2 type III). Operation time, intraoperative blood loss, fracture healing time, American Orthopaedic Foot and Ankle Society (AOFAS) ankle score, and complications were recorded to evaluate treatment effects.

Mean operation time was 72.5±15.8 minutes (range, 45–105 minutes) with a mean intraoperative blood loss volume of 86.4±17.3 mL (range, 50–150 mL). All 26 patients had good postoperative fracture healing. Mean union time was 19.2±4.4 weeks (range, 13–30 weeks). Average AOFAS ankle score was 87.3±9.2 (range, 68–99). No malunion, nonunion, limb-shortening deformity, or neurovascular injury occurred. Our results suggest that the posteromedial anatomical plate for the treatment of distal tibial fractures with anterior soft tissue injury is effective and results in no severe complications.
Arthroscopic Management of Stiff Elbow
Authors: Singh Harpreet , Nam Ki Young , Moon Young Lae
Published: June 2011

Elbow stiffness is a common problem encountered by orthopedic surgeons. Various management options have been described in the literature, including conservative measures and open and arthroscopic surgery. Arthroscopic management of stiff elbow remains controversial. The purpose of this study was to evaluate the functional results of arthroscopic management of stiff elbow.

Thirty patients with stiff elbow underwent arthroscopic release surgery and were followed up for an average of 27.3 months. Surgery included anterior and posterior capsular release, coronoid process debridement, bony spur excision, and loose body removal. Postoperative outcome was assessed using the Mayo Elbow Performance Score and range of motion at the elbow. Mayo Elbow Performance Score increased from a mean 64.5 preoperatively to a mean 83.17 postoperatively. Range of motion also improved, from a mean preoperative extension and flexion of 22.83° and 96.83°, respectively, vs a mean 10.83° and 120.84°, respectively, at final follow-up. No intra- or postoperative complication was seen in any case. Underlying etiology and timing of surgery influenced the end result, with better results seen in patients with traumatic etiology and those with a shorter duration of symptoms.

Arthroscopic release allows good visualization and rectification of intra-articular pathology and is a safe and effective tool for the management of stiff elbow.
Endogenous Heparinoids Induced Massive Hemorrhage Postoperatively Following THA

Published: June 2011

A 64-year-old woman presented with right hip pain of 6 years’ duration, accompanied by limping of 1 years’ duration. Preoperative pelvis radiograph showed narrowing of joint space, osteophyte formation, and cystis degeneration of the femoral head surrounded by bony sclerosis, without obvious collapse of the femoral head; the diagnosis was osteoarthrosis. The patient’s blood pressure on admission was 128/76 mm Hg. The patient had no special previous history. Preoperative blood and coagulation tests were normal. Total hip arthroplasty was performed via a posterolateral approach, and intraoperative bleeding was 400 mL. In the first 10 hours postoperatively, the drainage volume decreased slowly, the initial dose of 0.3 mL Fraxiparine was administered, and the blood pressure was 84∼92/45∼56 mm Hg. The drainage volume increased gradually, and 10 hours after administration of Fraxiparine, the drainage volume increased sharply and maintained at a high level. Protamine was applied and the drainage volume decreased sharply, furthermore, a high concentration of endogenous heparinoids were detected in the blood. Although no direct evidence were detected, it was clear that the massive hemorrhage was associated with administration of low-molecular-weight heparin (LMWH). The administration of LMWH combined with continuous low blood pressure caused by surgery and massive bleeding that resulted in low perfusion and inflammation in microcirculation, induced endogenous heparinoid synthesis in endothelial cells, and elevated concentration of endogenous heparinoids in blood led to more severe bleeding. Therefore, caution should be taken with administration of anticoagulant therapy in patients with massive hemorrhage, especially in patients with continuous low blood pressure.
Caring for Older Adults with Bipolar Disorder
Authors: Sorrell Jeanne M.
Published: June 2011

Bipolar disorder is a recurrent, chronic mental illness that has a profound impact on the lives of patients and their families and may require extensive use of mental health services. Although bipolar disorder is often considered an illness of young people, the disorder is being recognized as more common in older adults than previously thought. Much more research needs to be done to understand the impact of aging on the course and treatment of bipolar disorder. Evidence-based interventions for treatment of this disorder in older adults must be developed. Mental health nurses can play a key role in enhancing medication adherence, implementing structured psychosocial interventions, and carrying out research to enhance diagnosis and treatment of older adults with bipolar disorder.
LASIK Flap Thickness Profile and Reproducibility of the Standard vs Zero Compression Hansatome Microkeratomes: Three-Dimensional Display with Artemis VHF Digital Ultrasound
Authors: Reinstein Dan Z. , Archer Timothy J. , Gobbe Marine
Published: June 2011

Purpose:

To measure the mean flap thickness profile and calculate accuracy and reproducibility for standard and zero compression Hansatome microkeratomes (Bausch & Lomb).

Methods:

Retrospective study of 99 myopic eyes (51 patients) after LASIK using the standard or zero compression Hansatome microkeratomes (160-μm head). Reinstein Flap Thickness was calculated as preoperative epithelial thickness plus postoperative stromal component of the flap as measured by Artemis VHF digital ultrasound (ArcScan Inc). Mean and standard deviation flap thickness were calculated and plotted for a 10-mm diameter. Accuracy was calculated as the difference between the mean and intended flap thickness. Reproducibility was evaluated as the flap thickness standard deviation between eyes. Multivariate regression was performed for flap thickness against surgery order, atmospheric/vacuum pressure difference, spherical equivalent refraction, pachymetry, and keratometry.

Results:

For both Hansatome models, the mean flap thickness profile showed a thinnest region inferotemporally and thicker in the periphery of the inferotemporal edge and nasally. Mean central flap thickness was 140.3±17.5 μm (accuracy: −19.7 μm) and 119.0±12.7 μm (accuracy: −41.0 μm) for standard and zero compression Hansatomes, respectively. Eyes treated second were thinner (15.4 μm and 12.6 μm thinner for standard and zero compression Hansatomes, respectively). Multivariate regression improved the reproducibility to 14.8 μm (
P
<.05; surgery order, pachymetry) and 9.4 μm (
P
<.05; surgery order, atmospheric/vacuum pressure difference) for standard and zero compression Hansatomes, respectively.

Conclusions:

The flap thickness profiles were similar for standard and zero compression Hansatomes characterized by a thinnest region inferotemporally, rather than a meniscus shape as has been suggested previously. The zero compression Hansatome created thinner, more reproducible flaps. Surgery order and atmospheric/vacuum pressure difference might be used to obtain thinner flaps using a Hansatome.

Published: June 2011

Medullary thyroid carcinoma occurs in both sporadic (75%) and hereditary (25%) forms. The missense mutations of RET proto-oncogene in MTC development have been well demonstrated. To investigate the spectrum of predominant RET germline mutations in exons 10, 11, and 16 in hereditary MTC in Iranian population, 217 participants were included. Genomic DNAs were extracted from the leukocytes using the standard Salting Out/Proteinase K method. Mutation detection was performed through PCR-RFLP and DNA sequencing. In 217 participants, 43 missense mutations were identified in exons 10 (6%), 11 (13%), and 16 (0.9%). Moreover, a novel germline mutation was detected in exon 11 (S686N). Also four different polymorphisms were found in intron 16 in eight patients. The obtained data showed the frequency profile of RET mutations in Iranian individuals with MTC (19.8%). The most frequent mutation in our population was C634G whereas in most population it was C634R. Altogether, these results underline the importance of the genetic background of family members of any patient with MTC.
EGF and TGF-1 Effects on Thyroid Function
Authors: Mincione Gabriella , Di Marcantonio Maria Carmela , Tarantelli Chiara , D'Inzeo Sonia , Nicolussi Arianna , Nardi Francesco , Donini Caterina Francesca , Coppa Anna
Published: June 2011

Normal epithelial thyroid cells in culture are inhibited by TGF-1. Instead, transformed thyroid cell lines are frequently resistant to its growth inhibitory effect. Loss of TGF- responsiveness could be due to a reduced expression of TGF- receptors, as shown in transformed rat thyroid cell lines and in human thyroid tumors, or to alterations of other genes controlling TGF- signal transduction pathway. However, in thyroid neoplasia, a complex pattern of alterations occurring during transformation and progression has been identified. Functionally, TGF-1 acts as a tumor suppressor in the early stage of transformation or as a tumor promoter in advanced cancer. This peculiar pleiotropic behaviour of TGF- may result from cross-talk with signalling pathways mediated by other growth factors, among which EGF-like ligands play an important role. This paper reports evidences on TGF-1 and EGF systems in thyroid tumors and on the cross-talk between these growth factors in thyroid cancer.
Effect of Therapy by Using Advocate Spot-On Combination (Imidacloprid 10% and Moxidectin 2.5%) on Subcutaneous Dirofilariosis in Dogs
Authors: Paran Radmila Dobešová , Svobodová Vlasta
Published: June 2011

Dirofilaria(Nochtiella)repensis a filarioid parasite that causes subcutaneous dirofilariosis in dogs. Adults, while localized in subcutaneous tissues, lay embryos (microfilariae (mf)) into the blood stream of dogs, which constitute a reservoir for infection of other definitive or accidental hosts as humans. This study was carried out to assess the efficacy of spot-on combination of imidacloprid and moxidectin on microfilariaemia in naturally infected dogs. A group of 11 dogs was monthly examined for the presence of microfilariae in peripheral blood by modified Knott's test method. Treatment was administered monthly for 4 months. All dogs (i.e., 100%) became negative for microfilariaemia throughout the study. These results confirm the effect of the combination of imidacloprid and moxidectin onD.(Nochtiella)repens.

A Case of Cutaneous Infection Caused by Mycobacterium Szulgai with Progression to Acute Respiratory Distress Syndrome
Authors: Ohta Hiromitsu , Miyauchi Eisaku , Ebina Masahito , Nukiwa Toshihiro
Published: June 2011

A 59-year-old man presented with a skin eruption and bilateral swelling of the legs. Soon after the initial presentation, he developed acute respiratory distress syndrome (ARDS) with miliary lung nodules. Culture of samples from the skin ulcers, sputum, and bronchoalveolar lavage fluid all revealed Mycobacterium szulgai infection. The patient was successfully treated with antituberculosis drugs. M. szulgai infection is very rarely reported worldwide, and disseminated infection usually occurs in immunocompromised patients. However, the present patient was a non-immunocompromised case, although he was a hepatitis B virus carrier. While the progression to ARDS from M. tuberculosis infection is well known, this is the first case of M. szulgai infection progressing to ARDS.
The New North African Syndrome: A Fanonian Commemoration
Authors: Gibson Nigel C.
Published: June 2011

What better way to celebrate, commemorate, critically reflect on, and think through Fanon’s The Wretched of the Earth fifty years after its publication with a new North African syndrome: Revolution—or at least a series of revolts that continue to rock regimes across North Africa and the region.  Fanon begins The Wretched writing of decolonization as a program of complete disorder, an overturning of order—often against the odds—willed from the bottom up. Without time or space for a transition, there is instead an absolute replacement of one “species” of humanity by another. In periods of revolution, like the one we are experiencing today, such absolutes appear quite normal. Indeed, radical change becomes the “new normal” and the idea that revolutionary change is impossible is simply the rantings and ravings of the conservatives and reactionaries of the ancient regime. Too long buried under the weight of the tomes of academic discourse, Fanon has been resuscitated by the new dawn of North African revolutions. To celebrate Fanon, the revolutionary, all of a sudden seems contemporary and pertinent, while the musings of the critics who consigned him to postcolonial oblivion seem out of touch. But rather than continuing the painstaking work of exhuming Fanon from the postcolonial burial site, let us turn a commemoration of Fanon into an event. Indeed, why assume that a commemoration of Fanon after fifty years is not critical? Moreover why begin a contemporary engagement with Fanon assuming a priori the limits of his thought? Indeed, where to begin is a philosophic question. It is a question of “intention” as Edward Said puts it in one of his most radical and Vicoian works. Beginnings are revolutionary, implying return and repetition and, following Said, “a sort of historical dialectic that changes its character and meaning.” Vico, Said argues “said that the word human comes from root to bury” suggesting that “his humanistic philosophy” contained “elements of its own negation.”
Revolutionary in Counter-Revolutionary Times: Elaborating Fanonian National Consciousness into the Twenty-First Century
Authors: Gordon Jane Anna
Published: June 2011

One of the unique challenges of reading Les damnés de la terre (The Wretched of the Earth) today is that while it is an irredeemably revolutionary text, we live in a counter-revolutionary moment or in a global context that has tried very hard to discredit even the possibility of revolution. Fanon’s text does not only narrate the effective undertaking of an anti-colonial struggle—of what is required for people to identify the actual causes of their alienation and unfreedom and together to will their elimination—it also outlines the various, often dialectical challenges of restructuring a society from the bottom up. Guiding and evident in the latter is the flourishing of what Fanon suggestively called national consciousness. Elaborating its meaning and ongoing usefulness is the focus of this essay.

Timogel® vs Timolol 0.5% Ophthalmic Solution: Efficacy, Safety, and Acceptance
Authors: Rolle Teresa , Curto Daniela , Alovisi Camilla , Franzone Mauro , Brogliatti Beatrice , Grignolo Federico M.
Published: June 2011

Purpose

To evaluate the efficacy, safety, and tolerability of Timogel® preservative-free once daily compared to timolol 0.5% ophthalmic solution bid in patients with ocular hypertension (OHT) and patients with primary open-angle glaucoma (POAG).

Methods

A total of 75 patients with OHT and patients with POAG treated with timolol 0.5% bid with intraocular pressure (IOP) ≤21 mmHg were enrolled. They underwent complete ophthalmologic examination, IOP measurements (at trough and daytime curve), evaluation of side effects, Schirmer test, break-up time [BUT], blood pressure, heart rate, ocular diastolic perfusion pressure measurements, and acceptance (Comparison of Ophthalmic Medications for Tolerability). Patients switched to Timogel® and were re-evaluated 3 months later. The analysis of variance and the Pearson χ2 tests were used to test differences between the treatments.

Results

Intraocular pressure reduction at trough was 23.6% with timolol 0.5% and 22.3% with Timogel®. No statistical differences were observed in IOP values at trough and in the daytime curve between the 2 treatments. Local and systemic side effects were less frequent with Timogel® (hazard ratio: p<0.05). Patients demonstrated a significant improvement of Schirmer test and BUT (p<0.05) and a reduction of dryness and foreign body sensation (42.6% vs 15.4%; p<0.01) after switching to Timogel®. Mild and short-lasting blurred vision after Timogel® instillation occurred in about 18.5% of patients. A total of 82% of patients were satisfied or very satisfied with Timogel® vs 61% with previous treatment (p<0.01).

Conclusions

Timogel® preservative-free dosed once every morning has a 24-hour hypotensive effect with a better safety profile than timolol 0.5% bid and it is well-accepted by patients. The once-daily dosing improved acceptance and compliance.
Hammering Force during Cementless Total Hip Arthroplasty and Risk of Microfracture

Published: June 2011

During cementless stem fixation, impaction of the stem is occasionally complicated by bony injuries. Small fractures not visible to the eye during surgery or on post-operative radiographs may remain undetected, and the incidence of such injuries may be underestimated.

Employing the same techniques as those employed during total hip arthroplasty, we implanted cementless stems into artificial femora, with equivalent mechanical characteristics to living femora. The hammering force applied to the femur and the displacement of the stem and femur were measured using a load sensor and imaging, respectively. The von Mises stress generated in the femur during cementless stem press-fixation was also measured using finite element analysis.

Average hammering force under these conditions (9.25 kN) was sufficient to cause damage to the artificial femur. The first two of eight hammer strikes caused most displacement of the stem. The von Mises stresses generated by the first and second hammer strikes were 31 and 68 MPa, respectively. Applying a high average hammering force to the stem after displacement has ceased probably contributes to the generation of intraoperative fractures during cementless stem fixation.

Given that two strikes appeared to be sufficient, we believe that hammering force should be reduced to a micro-adjustment level after the second hit.
A Breakthrough Technique for the Removal of a Hemodialysis Catheter Stuck in the Central Vein: Endoluminal Balloon Dilatation of the Stuck Catheter
Authors: Hong Joon Ho
Published: June 2011

Background

Hemodialysis (HD) catheters can get stuck in the central vein after long-term use and their removal might become difficult especially in patients with fibrosed or occluded central veins. Herein, a breakthrough technique is reported for the easy removal of a stuck HD catheter from the central vein.

Case Report

Attempts were made to remove a tunneled double-lumen HD catheter from the central vein of a 74-year-old woman, only to find that the catheter was stuck. The patient was transferred to the operating room and a skin incision was made in the neck and the subcutaneous portion of the HD catheter was retrieved from the tunnel. Under fluoroscopy, a guide wire was inserted into one lumen of the HD catheter and advanced into the right atrium beyond the catheter tip. A 5 mm × 4 cm balloon angioplasty catheter was then inserted into the HD catheter lumen over the guide wire and advanced into the jugular vein junction of the HD catheter around the thoracic inlet. The balloon was inflated to its maximum dimension and pressure. This endoluminal dilatation of the HD catheter was continued by deflating the balloon and then pushing the angioplasty catheter 4 cm at a time towards the tip of the HD catheter in the right atrium. After a second balloon angioplasty catheter of 6 mm × 4 cm was used to expand the entire segment of the other lumen, the HD catheter was pulled out easily from the central vein without any resistance.

Comments

The endoluminal balloon dilatation of the HD catheter not only separates the stuck HD catheter from the adherent vein by breaking the adhesions between them, but also expands the vein simultaneously, thus enabling easy removal of the HD catheter.

Comparación Agroeconómica de dos Sistemas de Manejo de Plutella xylostella (L.) en Repollo en Estelí, Nicaragua
Authors: Garay Ernesto , Rueda Alfredo
Published: June 2011

De septiembre a diciembre de 2000 se compararon dos sistemas de manejo de Plutella xylostella, el manejo convencional calendarizado que hacen los productores de repollo y un sistema de Manejo Integrado de Plagas (MIP). La cantidad de larvas de plutella en el repollo manejado bajo el sistema MIP fue menor que en el manejado convencionalmente. Diadegma insulare parasitó a P. xylostella 30% en el sistema MIP y 7% en el sistema convencional (P = 0.001). Los costos diferenciales y totales fueron mayores en el sistema MIP, así como los ingresos bruto y neto (P = 0.04). El costo total aumentó 10% y el ingreso neto 201%, al cambiar del sistema tradicional al MIP. Palabras clave: Costo diferencial, MIP, parasitoide, plutella.

Análisis funcional del nicho ecológico de Syphrea sp. (Coleoptera: Chrysomelidae) asociado a Plukenetia volubilis L. (Euphorbiales: Euphorbiaceae) en la Amazonia peruana
Authors: Vecco Carlos D. , Pinedo Román , Fernández Miriam , Cave Ronald D.
Published: June 2011

Se evaluó el comportamiento y la distribución de adultos de Syphrea sp. en plantas de Plukenetia volubilis L. (Euphorbiaceae) bajo un sistema de cultivo de alta densidad en una zona cercana a Tarapoto, Perú. Se examinaron, diariamente, cinco plantas al azar por bloque en tres horarios (8:00-9:00, 13:00-14:00 y 17:00-18:00), teniendo en cuenta el número de adultos de Syphrea sp. en 10 hojas (haz y envés) y 10 inflorescencias tomadas aleatoriamente en cada estrato (inferior, medio, y superior). Se realizó un análisis funcional considerando 45 dimensiones que expresan las interacciones de tipo estructural, trófico, y temporal. Se calculó la amplitud del nicho (Bj) y determinó la dependencia de las poblacionales de Syphrea sp. con respecto a las dimensiones consideradas. Como resultado, se sugiere la especialización trófica y reproductiva de Syphrea sp. en hojas jóvenes e inmaduras, y quizás polen, en la parte externa de la planta, particularmente en el tercio superior. El comportamiento diurno del insecto y su tendencia a concentrarse al atardecer, podría sugerir que la alimentación es una actividad nocturna. Con respecto al aporte de elementos para la metodología del muestreo, se demostró la ventaja del uso de niveles estructurales referenciales (estratos por tercios) y se recomendó realizar las evaluaciones al atardecer.Palabras clave: Amplitud del nicho, comportamiento, distribución en planta, muestreo, sacha inchik.DOI: http://dx.doi.org/10.5377/ceiba.v50i1.192
Fault diagnosis for a class of descriptor linear parameter‐varying systems
Authors: Astorga‐Zaragoza C. M. , Theilliol D. , Ponsart J. C. , Rodrigues M.
Published: June 2011

In this paper, a model‐based fault estimation method for a particular class of discrete‐time descriptor linear parameter‐varying systems is developed. The main contribution of this work consists in the design of an observer that performs simultaneously both, the states estimation and the fault magnitude vectors, considered as unknown inputs. The conditions for the existence of such observer are given. Such conditions guarantee the observer stability and they are proved through a Lyapunov analysis combined with a linear matrix inequalities formulation. The fault estimation scheme is evaluated through numerical simulations. Copyright © 2011 John Wiley & Sons, Ltd.
Pretreatment of polypropylene films for the creation of thin polymer layers, part 1: The use of chemical, electrochemical, and UV methods
Authors: Urbaniak‐Domagala Wieslawa
Published: June 2011

The surface of a polypropylene (PP) film was activated with chemical, electrochemical, and physical methods, and the effectiveness of these methods was compared. The effects of PP activation were assessed with attenuated total reflection IR spectroscopy (ATR‐IR), SEM microscopy, and an analysis, based on the liquid contact angle, of the free energy components of the surface. The activation of the PP surface, which was dependent on the oxidizing medium, increased the energy of the PP surface layer and formed new chemical (carbonyl) groups, which were identified by IR (ATR) absorption spectroscopy and confirmed by selective surface dyeing. The treatments were ranked in the following order of increasing effectiveness: UV irradiation < 3M nitric acid < 30% hydrogen peroxide < silver nitrate (electrochemical method) < chromic mixture. © 2011 Wiley Periodicals, Inc.

Imprinted poly (vinyl alcohol) as a promising tool for xanthine derivatives separation
Authors: Patachia Silvia , Croitoru Catalin
Published: June 2011

In this work, we report the obtaining of an ecological imprinted polymer for the selective sorption of xanthine derivatives (caffeine and theobromine) from aqueous solutions, through an innovative approach. Poly (vinyl alcohol) [PVA]‐xanthine films have been obtained by aqueous solution casting. PVA crosslinking has been performed by using glutaraldehyde in gaseous phase. Template elimination has been achieved by “washing” of crosslinked films with water. To check the polymer imprentation and to determine the imprinted material effectiveness in xanthines separation, sorption studies have been performed. Freundlich, Langmuir, BET, Extended Langmuir models, and Scatchard analysis have been applied on the experimental data to better characterize the sorption mechanism. Fluorescence microscopy has been proposed as suitable method to check the imprentation level of the polymer. The information obtained by this method is in good agreement with the values for the efficiency of the imprinted polymer and could serve as an easier tool for prediction of the imprinted polymers performance. © 2011 Wiley Periodicals, Inc.

Voyeurism, Violence, and the Power of the Media: The Reader's/Spectator's Complicity in Jelinek's The Piano Teacher and Haneke's La Pianiste, Caché, The White Ribbon
Authors: Landwehr Margarete Johanna
Published: June 2011

Both Jelinek's and Haneke's works focus on the media's detrimental effect on relationships. Debord's The Society of the Spectacle and Baudrillard's The Vital Illusion serve as the basis for a discussion of Jelinek's Vienna, which consists of a society of voyeurs in which spectatorship replaces intimate engagement. The author draws upon media and film studies that link an increase in violent images with increased aggression in her analysis of Haneke's films that depict the role the media plays in violent behavior. The article concludes with a discussion of the ways in which both artists provoke the readers/viewers into an awareness of their own voyeuristic roles as passive bystanders and the responsibility that entails.

A Contribution from Film to a Psychoanalytic Explanation of Large Consequence – Haneke's Affirmation of Historical Antecedents to Nazism
Authors: Parens Henri
Published: June 2011

In his masterpiece, The White Ribbon, writer and film‐maker Michael Haneke creates a tale that jars the viewer with his portrayal of life in a (German) village at the threshold of World War I. But he also gratifies this psychoanalytic viewer in two ways: (1) in the historically documented realistic portrayal of harsh child rearing and its then‐unrecognized potential highly destructive consequences; and (2) in the psychoanalytic cogency of his portrayal, given that established psychoanalytic and psychological theorizing compelled by evidence‐based findings asserts just what Haneke tells us: that abuse (and neglect) of children generate the hostile‐destructive‐laden psychodynamic that underlies the formation of delinquent and criminal characterology.

Social Decision Heuristics in the Use of Shared Resources
Authors: Allison Scott T. , Messick David M.
Published: June 2011

The goals of the present study were (1) to demonstrate again that subjects in social decision tasks involving shared resources cannot be modelled as strategic money maximizers, and (2) to investigate further factors that affect the use of what we have called social decision heuristics. Subjects were led to believe that they were the first of six group members to extract points from a common pool of points. Each point extracted could possibly be exchanged for cash. The independent variables were the magnitude of the payoffs that subjects could receive (high vs. low), the divisibility of the resource (divisible vs. nondivisible), the perceived control of the last members over the group's outcomes (fate control vs. no fate control), and subjects' social values (cooperative vs. noncooperative). The results indicated that subjects anchored their decisions on an equal division heuristic. Subjects withdrew the fewest number of points when the resource was divisible, the payoffs were low, and there was fate control. The most points were taken when the resource was nondivisible, the payoffs were high, and subjects were classified as noncooperative. A model of the choice process in this task is discussed.
Assessment Uncertainty Technology for Making and Defending Risky Decisions
Authors: Brown Rex V.
Published: June 2011

Risky decisions are often difficult to make or defend because assessments of key facts are themselves subject to uncertainty. Theory bearing on this second‐order ‘assessment uncertainty’ (AU) has found little practical application. A methodology is proposed for representing AU in a form where it can be understood, judgmentally checked and effectively used in common decision situations, including some guidance on how to elicit or indirectly measure AU. It extends well‐established personal probability logic, with primary focus on predicting shifts in first‐order factual assessments which might result from new developments — whether these are realistically possible or ‘ideal.’ The approach attempts to be prescriptive, in that its input can be readily measured, its output fits intended use and user, and the intervening procedures are logically sound without being too burdensome. Successful application is illustrated in the context of a regulatory decision on whether a reactor should be required to install a costly safety feature.
