Contingent Effects of Quality Signaling: Evidence from the Indian Offshore IT Services Industry
Authors: Gao Guodong (Gordon) , Gopal Anandasivam , Agarwal Ritu
Published: April 2010

We examine the heterogeneous returns to third-party quality signals in the context of the Indian software services industry. Prior theory has argued that quality certification is important in markets characterized by information asymmetry. However, there is limited understanding of the contingent factors that influence the efficacy of the quality signal. We focus on capability maturity model (CMM) certification, which is granted on the basis of a rigorous audit of software vendor's internal quality-oriented software construction practices, as a signal of unobservable quality. Drawing upon prior research in strategy and economics, we theorize that the impacts of CMM certification on a vendor's export performance are conditional on factors reflecting the vendor's strategy (diversification and location) and its competitive environment (the extent of CMM penetration in the vendor's competition). Analysis of panel data supports our predictions related to the contingent value of CMM certification, and shows that a software service provider gains more from certification in terms of its software exports when its service offerings are diversified, when it chooses to locate away from a cluster of other software service firms, and when the extent of CMM penetration in the competition is low. This study extends prior research in the information value of a quality signal on a firm's demand side that has, for the most part, focused solely on direct effects. We discuss the implications of our findings for the strategic trade-offs that managers of software service firms need to make.

Dell's supply chain for desktops involves Asian vendors shipping components by sea to several U.S. plants. Although suppliers are responsible for shipping enough inventory to meet total needs across all production sites, Dell can reroute and expedite their shipments while in transit, and also transfer on-hand inventory in order to balance supply across sites. This paper describes the development, implementation, and impact of the process and optimization-based control system now used by Dell to address this supply-routing challenge for its U.S.-bound monitors. In a first phase, Dell created a new job definition focused solely on supply routing and implemented a supporting visualization tool. In a second phase, a decision support system relying on a mixed-integer programming formulation was implemented, overcoming two main challenges: (i) the estimation of shortages as a function of expected inventory, accounting for actual forecast quality; and (ii) the estimation of a meaningful shortage cost. This new methodology is estimated to have reduced Dell's inventory-repositioning costs for monitors by about 60%.
ASAP: The After-Salesman Problem
Authors: Klundert Joris van de , Wormer Laurens
Published: April 2010

We consider the operational scheduling or dispatching problem of assigning servicemen to service requests that arrive in real time. The objective is to optimize responsiveness, i.e., to minimize waiting in excess of a promised response time. We study how responsiveness is influenced by modeling decisions and solution methods that arise when solving the dynamic problem by repeatedly solving real-time problems. Most results are derived using a set-partitioning based solution approach, which is shown to perform best among considered alternatives. Our research is based on a large-scale real-life application regarding roadside service assistance.
Reliable Facility Location Design Under the Risk of Disruptions
Authors: Cui Tingting , Ouyang Yanfeng , Shen Zuo-Jun Max
Published: April 2010

Reliable facility location models consider unexpected failures with site-dependent probabilities, as well as possible customer reassignment. This paper proposes a compact mixed integer program (MIP) formulation and a continuum approximation (CA) model to study the reliable uncapacitated fixed charge location problem (RUFL), which seeks to minimize initial setup costs and expected transportation costs in normal and failure scenarios.

The MIP determines the optimal facility locations as well as the optimal customer assignments and is solved using a custom-designed Lagrangian relaxation (LR) algorithm. The CA model predicts the total system cost without details about facility locations and customer assignments, and it provides a fast heuristic to find near-optimum solutions. Our computational results show that the LR algorithm is efficient for mid-sized RUFL problems and that the CA solutions are close to optimal in most of the test instances. For large-scale problems, the CA method is a good alternative to the LR algorithm that avoids prohibitively long running times.
Laparoscopic-assisted enteroscopy
Authors: Baker S , Nisar A , Paice AG , Abdulaal Y
Published: April 2010

This case demonstrates that laparoscopic-assisted enteroscopy (LAE) is a safe and effective technique to aid diagnosis and treatment of small bowel lesions that are difficult to identify with traditional and advanced imaging and interventional techniques. In patients where definite bowel lesions are identified on small bowel capsule endoscopy or small bowel enteroscopy, LAE can be extremely valuable in pinpointing the lesion intra-operatively. This technique may have certain merit for laparoscopic Crohn’s stricturoplasty.

Early restoration of intestinal continuity in acute mesenteric ischaemia using Bishop–Koop stoma
Authors: Arsalani-Zadeh Reza , Kallam Ramana , Khan Shakeeb , Macfie John
Published: April 2010

Introduction

Acute mesenteric ischaemia frequently requires extensive bowel resection. Primary anastomosis is unsafe necessitating exteriorisation of proximal small bowel and distal colon. Inevitably, therefore, patients are left with high output stomas with concomitant fluid and nutritional problems.

Subjects

We present two cases of acute mesenteric ischaemia both of which required extensive bowel resection. In both patients, we re-established intestinal continuity early by fashioning a Bishop–Koop type of reconstruction.

Results

Both patients had uneventful postoperative recoveries with no stoma-related complication or anastomosis problems. Neither patient required prolonged parenteral therapy.

Conclusions

Bishop–Koop procedure may be used safely in a selected group of patients, with potential advantages of early restoration of intestinal continuity and easier closure.
Implantation of an intercostal nerve stimulator for chronic abdominal pain
Authors: Johnson RD , Green AL , Aziz TZ
Published: April 2010

Chronic abdominal pain is not uncommon and can be difficult to manage. We present the case of a 17-year-old man with a 4-year history of chronic abdominal pain. The patient had previously undergone abdominal surgery by way of laparoscopic appendicectomy and right nephrectomy for a mal-rotated kidney. The patient continued to suffer right-sided abdominal pain which was not controlled by analgesia. We report the successful implantation of a right D11 intercostal nerve stimulator to control the patient’s pain. This is the first report of an implantable intercostal nerve stimulator to control intractable chronic abdominal pain.
Spontaneous retroperitoneal abscess as the first clinical manifestation of a non-functioning retroperitoneal paraganglioma
Authors: Arrabal-Polo Miguel Angel , Arrabal-Martin Miguel , Lopez-Leon Victor Manuel , Abad-Menor Felix , Valle-Diaz de la Guardia Francisco , Mijan-Ortiz Jose Luis , Zuluaga-Gomez Armando
Published: April 2010

We demonstrate a novel clinical presentation of paraganglioma not described in the literature. The paraganglioma is a catecholamine secretory, or non-secretory, neuroendocrine tumour that derives from chromaffin cells. Its frequency, with regard to pheochromocytoma, is low, and the abdominal region is the most frequent localisation site, followed in importance by the cervical region. We report the case of a 54-year-old woman diagnosed with a retroperitoneal abscess; after drainage of the lesion, samples indicated necrotic paraganglioma cells, so it was decided to conduct a survey to determine catecholamine levels in urine, and carry out a MIBG gammagraphy, which described a non-functioning retroperitoneal paraganglioma that underwent surgical removal. There was no residual disease after 3-month follow-up.
Aerial exposure and desiccation tolerances are correlated to species composition in “green tides” of the Salish Sea (northeastern Pacific)
Authors: Nelson Timothy A. , Olson Jennifer , Imhoff Lydia , Nelson Amorah V.
Published: April 2010

Relatively little is known about the causes of species distribution within macroalgal blooms occurring on or over soft substrata. We examine the roles of aerial exposure and desiccation in determining elevational patterns of two dominant bloom-forming ulvoid algae, Ulva lactuca and Ulvaria obscura, on the northeastern Pacific coast. These species were stressed with constant desiccation time, desiccation to a constant water potential, and desiccation to a fixed water loss. As a measure of health, we examined net photosynthesis by oxygen evolution or photosynthetic yield via pulse amplitude modulated fluorometry. By all measures, Ulva was physiologically superior in the intertidal zone. Under constant exposure, it desiccated more slowly than Ulvaria. When desiccated to a constant dryness, Ulva better maintained photosynthetic parameters. These observations are consistent with Ulva's usual dominance over Ulvaria in intertidal macroalgal blooms. Given these and other observed differences between the two species, natural resource managers should not regard the two as ecologically equivalent, even though they have similar functional forms.

The diagnosis of Cushing's syndrome: an Endocrine Society Clinical Practice Guideline: commentary from a European perspective
Authors: Guignat Laurence , Bertherat Jérôme
Published: April 2010

Cushing's syndrome is considered a rare disease and its diagnosis can be challenging. Establishment of evidence-based recommendations is difficult. In 2008, several national and international consensus recommendations for the diagnosis or management of Cushing's syndrome were reported. The Endocrine Society, with the participation of the European Society of Endocrinology, has developed a task force to update recommendations for the diagnosis of Cushing's syndrome. The main aspects of these recommendations are presented in this article and discussed in the context of current research efforts in Europe focusing on the improvement of diagnosis and management of rare diseases including adrenal disorders such as Cushing's syndrome.
Alterations in circulating adiponectin levels occur rapidly after parturition
Authors: Fuglsang Jens , Sandager Puk , Frystyk Jan , Møller Niels , Flyvbjerg Allan , Ovesen Per
Published: April 2010

Objective

To determine the levels of adiponectin and its subforms before and immediately after delivery to estimate the effect of cessating advanced pregnancy on circulating adiponectin levels.

Design and methods

In a cohort of 37 women with uncomplicated singleton pregnancies and 6 women with twin pregnancies, serum adiponectin was measured before caesarean section (CS) in the fasting state, and 24 and 48 h after CS.

Results

Serum adiponectin levels declined within 24 h of delivery from median 8.34 mg/l (range 5.57–20.47) to 6.81 mg/l (4.16–17.39) after 24 h and 6.84 mg/l (3.83–17.42) after 48 h. This corresponded to a relative decrease to 83±6 and 81±7% of pregnant values after 24 and 48 h respectively (P<0.001, ANOVA). In twin pregnancies, maternal adiponectin levels displayed a decrease that was the same as that displayed by them after birth (P<0.001).

High-molecular weight adiponectin constituted 50±8% (range 34–68%) of total adiponectin. Absolute changes in adiponectin levels after delivery were most pronounced in this subfraction. The percentage medium-molecular weight adiponectin decreased slightly, but significantly (from 37±6 to 35±5%,P<0.001), and a similar statistically significant rise was observed in the low-molecular weight fraction (from 13±2 to 15±3%;P<0.001) within 48 h of delivery.

Conclusions

Decreases in adiponectin levels occur shortly after delivery, and adiponectin subforms initiate the changes towards the non-pregnant state.
Likelihood-Free Inference of Population Structure and Local Adaptation in a Bayesian Hierarchical Model
Authors: Bazin Eric , Dawson Kevin J , Beaumont Mark A
Published: April 2010

We address the problem of finding evidence of natural selection from genetic data, accounting for the confounding effects of demographic history. In the absence of natural selection, gene genealogies should all be sampled from the same underlying distribution, often approximated by a coalescent model. Selection at a particular locus will lead to a modified genealogy, and this motivates a number of recent approaches for detecting the effects of natural selection in the genome as “outliers” under some models. The demographic history of a population affects the sampling distribution of genealogies, and therefore the observed genotypes and the classification of outliers. Since we cannot see genealogies directly, we have to infer them from the observed data under some model of mutation and demography. Thus the accuracy of an outlier-based approach depends to a greater or a lesser extent on the uncertainty about the demographic and mutational model. A natural modeling framework for this type of problem is provided by Bayesian hierarchical models, in which parameters, such as mutation rates and selection coefficients, are allowed to vary across loci. It has proved quite difficult computationally to implement fully probabilistic genealogical models with complex demographies, and this has motivated the development of approximations such as approximate Bayesian computation (ABC). In ABC the data are compressed into summary statistics, and computation of the likelihood function is replaced by simulation of data under the model. In a hierarchical setting one may be interested both in hyperparameters and parameters, and there may be very many of the latter—for example, in a genetic model, these may be parameters describing each of many loci or populations. This poses a problem for ABC in that one then requires summary statistics for each locus, which, if used naively, leads to a consequent difficulty in conditional density estimation. We develop a general method for applying ABC to Bayesian hierarchical models, and we apply it to detect microsatellite loci influenced by local selection. We demonstrate using receiver operating characteristic (ROC) analysis that this approach has comparable performance to a full-likelihood method and outperforms it when mutation rates are variable across loci.
Feed-Forward Regulation of a Cell Fate Determinant by an RNA-Binding Protein Generates Asymmetry in Yeast
Authors: Wolf Joshua J , Dowell Robin D , Mahony Shaun , Rabani Michal , Gifford David K , Fink Gerald R
Published: April 2010

Saccharomyces cerevisiae can divide asymmetrically so that the mother and daughter cells have different fates. We show that the RNA-binding protein Khd1 regulates asymmetric expression of FLO11 to determine daughter cell fate during filamentous growth. Khd1 represses transcription of FLO11 indirectly through its regulation of ASH1 mRNA. Khd1 also represses FLO11 through a post-transcriptional mechanism independent of ASH1. Cross-linking immunoprecipitation (CLIP) coupled with high-throughput sequencing shows that Khd1 directly binds repetitive sequences in FLO11 mRNA. Khd1 inhibits translation through this interaction, establishing feed-forward repression of FLO11. This regulation enables changes in FLO11 expression between mother and daughter cells, which establishes the asymmetry required for the developmental transition between yeast form and filamentous growth.
Decreased Energy Metabolism Extends Life Span inCaenorhabditis elegansWithout Reducing Oxidative Damage
Authors: Van Raamsdonk Jeremy Michael , Meng Yan , Camp Darius , Yang Wen , Jia Xihua , Bénard Claire , Hekimi Siegfried
Published: April 2010

On the basis of the free radical and rate of living theories of aging, it has been proposed that decreased metabolism leads to increased longevity through a decreased production of reactive oxygen species (ROS). In this article, we examine the relationship between mitochondrial energy metabolism and life span by using the Clk mutants in Caenorhabditis elegans. Clk mutants are characterized by slow physiologic rates, delayed development, and increased life span. This phenotype suggests that increased life span may be achieved by decreasing energy expenditure. To test this hypothesis, we identified six novel Clk mutants in a screen for worms that have slow defecation and slow development and that can be maternally rescued. Interestingly, all 11 Clk mutants have increased life span despite the fact that slow physiologic rates were used as the only screening criterion. Although mitochondrial function is decreased in the Clk mutants, ATP levels are normal or increased, suggesting decreased energy utilization. To determine whether the longevity of the Clk mutants results from decreased production of ROS, we examined sensitivity to oxidative stress and oxidative damage. We found no evidence for systematically increased resistance to oxidative stress or decreased oxidative damage in the Clk mutants despite normal or elevated levels of superoxide dismutases. Overall, our findings suggest that decreased energy metabolism can lead to increased life span without decreased production of ROS.
Essential Loci in Centromeric Heterochromatin of Drosophila melanogaster. I: The Right Arm of Chromosome 2

Published: April 2010

With the most recent releases of the Drosophila melanogaster genome sequences, much of the previously absent heterochromatic sequences have now been annotated. We undertook an extensive genetic analysis of existing lethal mutations, as well as molecular mapping and sequence analysis (using a candidate gene approach) to identify as many essential genes as possible in the centromeric heterochromatin on the right arm of the second chromosome (2Rh) of D. melanogaster. We also utilized available RNA interference lines to knock down the expression of genes in 2Rh as another approach to identifying essential genes. In total, we verified the existence of eight novel essential loci in 2Rh: CG17665, CG17683, CG17684, CG17883, CG40127, CG41265, CG42595, and Atf6. Two of these essential loci, CG41265 and CG42595, are synonymous with the previously characterized loci l(2)41Ab and unextended, respectively. The genetic and molecular analysis of the previously reported locus, l(2)41Ae, revealed that this is not a single locus, but rather it is a large region of 2Rh that extends from unextended (CG42595) to CG17665 and includes four of the novel loci uncovered here.

A Batthyányak és Carlo della Torre szerződése a rohonci templom építésére
Authors: Koltai András
Published: April 2010

Count Ádám Batthyány (1610–1659), proprietor of Rohonc in Western Hungary (today Rechnitz, Austria) converted to Catholicism in 1629. He expelled Protestant preachers from his estates in 1634 and tried to establish Catholic practices in Rohonc too. This town had two parishes (Croatian and German) but their common used medieval church perished. On June 23, 1657 he signed a contract in Italian with master builder Carlo della Torre to build a new church for 1900 florins. Carlo della Torre directed all major constructions of Ádám Batthyány partly on his own plans from 1646. Apart from Rohonc, he built a notable church for the Dominicans in Szombathely between 1668 and 1673. After the count's death his sons concluded a new contract for the Rohonc church with the master on July 1, 1659 (this German text is presented here), which was practically identical with the one of 1657 (although only the precise of its contents is known). The pay increased to 2000 florins. The building was finished in 1677, but the interior furnishing tarried for decades.
I. Lipót császár változó arcai Almanach Royalokon

Wall calendars had become an important part of regal representation by the end of the 17th century. The French monarchs, German ecclesiastic and secular prince-electors, and councils of imperial cities ordered wall calendars, mainly from famous Augsburg engravers, decorated with important events and successes of the previous year. The three wall calendars of Leopold I that have survived in the Berlin leaflet collection are impressive representations of the important period shifts in Leopold I's regal representation. The first calendar was made for the year 1661. The print shows the imperial predecessors of Leopold I, stressing his legitimacy by demonstrating how important emperors of the Holy Roman Empire came from the house of Habsburg. The wall calendar is an organic part of the peculiar propaganda campaign that emerged in connection with the 1658 election of Leopold I as emperor and in which the prince-electors emphasised their political predominance within the Holy Roman Empire. The second calendar sheet was made for the year 1686, calling attention to the great successes achieved in the anti-Turk war during 1685, putting the emperor's person in the centre. The emperor occurs in the characteristic accessories of the court as a victorious Roman war-lord and emperor. Although the victories of Venice over the Turks were also recorded on the print, Leopold is represented as the victor of the holy was against the Turks, suggesting the divine origin of the victories. The third sheet is a summary of Emperor Leopold's reign, as it was made for the year following his death, 1706. In this print of 50 small emblems, Emperor Leopold figures against Louis XIV as “the other sun” in Europe's sky. This propaganda publication, made probably with the Jesuits' cooperation, represents the Habsburg Empire as the most important European power, the victor in the Habsburg–French conflict that spanned the time of Leopold's reign. The Augsburg-made print attests not only to the state-theoretical erudition and high-quality political learning of its makers but also to their profound knowledge of the natural sciences and their receptivity to scientific innovations.
A MIÉNK művészegyesület története a korabeli sajtó tükrében II.
Authors: Tímár Árpád
Published: April 2010

The first part of the study appeared in issue no. 2008/1 of Acta Historiae Artium. The second part is concerned with the press coverage of the society's second and most momentous exhibition in 1909, taking into account all supportive, appreciative reviews as well as the disapproving, unsympathetic ones by conservative critics. The exhibition multiplied the attacks against the group; a spectacular campaign was organized to celebrate the art of Gyula Benczúr, and at the general assembly of the National Salon members of MIÉNK were ousted from the board and Lajos Ernst was removed from the leadership. To offset the attacks, György Bölöni organized a series of exhibitions, showing works of Rippl-Rónai and younger MIÉNK members in Kolozsvár, Nagyvárad and Arad. Parallel with that, the organization called Artists' House led by Miklós Rózsa was emerging and in December 1909 an exhibition entitled New Pictures was staged of works by artists later to be rallied in the group The Eight. All this fermented the slow disintegration of MIÉNK, which held its last exhibition in 1910 and then dissolved.
Paulus Antonius Senser (1716–1758) festő és köre
Authors: Repanić-Braun Mirjana
Published: April 2010

There are registrations of baptism in Eszék (Osijek, Croatia) in 1735 and 1740 including the name of Paulus Antonius Senser. He first appeared in Pécs in 1742 where he cleaned the Saint Emeric altar picture of the cathedral. After the death of his first wife and the christening of his children born to his second wife (1744, 1745), his name was included in the city's tax register and in 1747 he was admitted among the town-dwellers with citizen's rights together with two fellow painters (Ioannes Erdely and Franciscus Antonius Witz). Instead of paying the 30 florins required, he painted a Iustitia picture for the municipal council – which may be identical with the Solomon's judgment picture in the Janus Pannonius Museum. He painted the still extant Miracle of the loaves for the refectory of the seminary in 1746 or 1747. In 1756 he created the Supper at Emmaus for the Franciscans in Vukovár (Vukovar, Serbia) for a fee of 90 florins. This picture has disappeared together with two altar pictures in recent years. The only signed work of his, Feast at Portiuncula, a gift by the vicar of ðakovo in 1753, survives in Visoko in Bosnia-Hercegovina. A collation of some long-known and mostly recently explored archival data with the extant works of Master Paulus permits the assumption that the Eszék and Pécs masters were one and the same painter who died in Pécs in his 41st year on 8 January 1758. His pictures contain distinctly idiosyncratic features on the basis of which further paintings commissioned mainly by Franciscans and Capuchins in Máriagyűd, Pécs, Slavonski Brod, Siklós and Eszék can be attributed to him. In rendering pictures of saints he adopted some clear-cut stereotypes: rose-cheeked Madonnas with a charming smile (e.g. Maria Victoria around 1753, Kraljeva Suteska), characteristic male saints with suffering faces and drooping mouths (Sts Francis, Antony, Didak, Bonventura, Sebastian, Rock – Eszék, Slavonski Brod, ðakovo). In the background of an altar picture of a saint, the virtuosic rendering of a tiny scene of the respective legend in an architectural setting can usually be seen. The fourteen helping saints (Máriagyűd, Siklós), the Miracle of the loaves and the Stoning of St Stephen (Pécs), the Supper at Emmaus (Vukovár) are crammed with excited, often caricaturistic figures with vigorous gestures. These characteristics and the historical data appear to substantiate the attribution of two paintings on the theme of Solomon's judgment (Eszék, Municipal Gallery and Janus Pannonius Museum, Pécs), both probably ordered by the municipalities. Senser worked with assistants, conducting a workshop: the hand of his pupils can be discerned in several baroque altar pictures of former Southern Hungary. On account of its influence, his extensive and far from complete oeuvre has a salient place in both Hungarian and Croatian art history.
Adalékok Worbes Henrik (1765–1836) pesti asztalosról
Authors: Rostás Péter
Published: April 2010

Originating in Northern German areas, furniture-maker of the Lutheran faith Henrik Worbes settled in Pest after nearly ten years of journeying in the 1790s. At first he worked as a journeyman and from 1802, after four years of dispute with the guild, as master. From 1805 he owned a house of his own in Soroksári (today Ráday) street which he asked the permission of the Embellishing Committee to enlarge in 1810. His home and workshop were in this building until his death. Worbes' religious affiliation probably influenced his strategy of assimilation in Pest. He contributed to the furnishing of the prayer room planned by Johann Krausz in Deák square and later to that of the church planned by Mihály Pollack. Only a single piece of furniture attributable to his workshop is known: it is a Flötensekretär kept in the Kiscell Museum. It was commissioned by another member of the Lutheran congregation of Pest, the watchmaker Carl Payer and created by the journeyman Johann Gottlieb Hentschel working in Worbes' shop. The study also touches on the contract between another Lutheran person, Martin von Sturmann and the cabinet-makers of the Pest guild including Worbes to furnish his mansion at Galgagyörk dated 1806, and discusses the foiling of the plan. In doing so, the study exposes the fundamental structural problems that led to the dissolution of the cabinet-makers' community a few years after its emergence as well as the tendency of transformation in the first decade of the 19th century to concentrate all interior decorating work in one hand.

Published: April 2010

On the American continent, almost 15 million people are affected by Chagas disease, resulting in important economic and social damages. Dogs are considered to be an excellent experimental model to study Chagas' disease; as a result, in this research, the characterization of cardiovascular abnormalities was performed in dogs experimentally infected with Trypanosoma cruzi (the Colombian strain) that were at chronic stage. Thirteen adult female dogs were evaluated by electrocardiographic, echocardiographic, hematological and biochemical analyses in the chronic phase. For the electrocardiographic studies, respiratory sinus arrhythmia was the predominant rhythm during the entire research period (49.55% to 67%), with a low prevalence of right bundle branch block (0-13%) and first-degree atrioventricular block (0-14%). The spectral Doppler echocardio-graphy showed E and A mitral wave reversal (0.71±0.17), confirming the diastolic dysfunction present in all dogs. An increase in the enzymes activities was detected in the serum analysis, indicating myocardial injury by the infection. Six dogs died during the follow-up. In this way, the clinical characterization of experimentally infected dogs, as described here, increases the knowledge and allows for recognition of the behavioural modifications present in Chagas' disease in affected dogs.

O objetivo deste experimento foi isolar a musculatura epaxial da medula espinhal de cães submetidos à laminectomia dorsal modificada (LDM) e averiguar se os músculos influenciaram na formação da fibrose epidural, na compressão medular e no aparecimento dos sinais neurológicos. Para isso, dez cães hígidos foram submetidos à LDM entre as vértebras T13 e L1 e distribuídos aleatoriamente em dois grupos denominados controle (I) onde a medula espinhal permaneceu exposta sem a presença de implante, e tratado (II)onde foi colocado um im-plante a base de alumínio entre a musculatura epaxial adjacente e a medula espinhal exposta pela LDM. As avaliações constaram de exames neurológicos diários até 180 dias de pós-operatório (PO); mielografia, decorridos 15, 30 e 60 dias de PO; e avaliação macroscópica mediante a reintervenção cirúrgica. Não houve diferença durante as avaliações neurológicas. Aos 15 dias de PO, foi verificado na mielografia, que o grau de compressão da linha de contraste foi maior no grupo tratado (P<0,05) quando comparado ao grupo controle, não havendo diferença dos demais tempos estudados. Na avaliação macroscópica, pode-se observar que no Grupo II, a musculatura epaxial adjacente à medula espinhal não estava em contato com a fibrose epidural, diferentemente do grupo controle. O implante pôde ser removido facilmente e apresentava discreto grau de deformidade crânio-dorsal. Pode-se concluir que a musculatura epaxial adjacente é isolada da medula espinhal pelo implante à base de alumínio em cães submetidos à LDM, e esta não influencia na formação da fibrose epidural, compressão medular e no aparecimento dos sinais neurológicos.

Para a obtenção do diagnóstico definitivo do osteossarcoma realizam-se exames citopatológico e histopatológico. O material para exame citopatológico é coletado através de punção aspirativa por agulha fina (PAAF), já para a realização do exame histopatológico é necessário uma amostra de tamanho maior, geralmente conseguida através de biópsia incisional. Este trabalho tem como objetivo desenvolver uma técnica de coleta de material em cães com suspeita de osteossarcoma através de PAAF para a realização de exame histopatológico. Foram coletadas duas amostras de 12 cães suspeitos de osteossarcoma por PAAF. O material obtido pela primeira coleta foi utilizado para confirmar o diagnóstico através do exame citopatológico, enquanto que o material oriundo da segunda coleta foi fixado em formol a 10% para a análise histopatológica. Quatro das 12 amostras (33,3%) avaliadas histopatologicamente pela metodologia proposta obtiveram também o diagnóstico de osteossarcoma. Esses resultados apontam para uma possível adequação da técnica de coleta de material por PAAF para exame histopatológico.

Com o aumento do número de intervenções cirúrgicas para a remoção da catarata em cães, observa-se a necessidade de exames específicos que devem ser realizados antes da indicação cirúrgica. A catarata é uma das principais causas de cegueira em cães. Nos estágios mais avançados, impossibilita o exame fundoscópico e inviabiliza a observação de alterações retinianas como a atrofia progressiva da retina (APR), degeneração retiniana hereditária de acometimento bilateral que, quando diagnosticada, contra-indica a cirurgia. Com o intuito de reestabelecer a visão, o eletrorretinograma de campo total (Full field ERG) torna-se indispensável na avaliação pré-cirúrgica da remoção da catarata. Como os cães da raça Cocker Spaniel Inglês são predispostos à catarata e a degenerações retinianas, objetivamos neste estudo avaliar as respostas dos ERGs realizados nestes animais. Foram avaliados 136 eletrorretinogramas de cães da raça Cocker Spaniel Inglês (62 machos e 74 fêmeas, com idades entre 3 e 15 anos) no período de Setembro de 2004 a Maio de 2009. Todos os animais apresentavam baixa de visão e catarata durante o exame. O diagnóstico de degeneração retiniana foi baseado nos valores de amplitude pico a pico e tempo de culminação da onda-b nas 3 respostas (resposta escotópica de bastonetes, máxima resposta e resposta fotópica de cones), idade do paciente e estágio de maturação da catarata. Nos cães sem degeneração retiniana, a média da amplitude e do tempo de culminação nas três respostas obtidas foram, respectivamente: 71,55mV/65,15ms; 149,17mV/33,03ms; 31,06mV/27,90ms. Nos cães com degeneração retiniana, 38 animais apresentaram ERG extinto. Dentre os restantes que apresentavam baixas respostas, a média da amplitude e do tempo de culminação nas três respostas obtidas foram, respectivamente: 12,88mV/65,04ms; 24,16mV/36,25ms; 8,36mV/31,38ms. Foi observado que em 122 animais (89,7%) os exames eram compatíveis com diagnóstico de atrofia progressiva da retina. Frente aos resultados obtidos, conclui-se que os cães da raça Cocker Spaniel Inglês portadores de catarata devem ser submetidos ao eletrorretinograma de campo total antes da remoção cirúrgica devido à alta incidência de degeneração retiniana nesta raça.

Foram caracterizados os sorotipos, o perfil de sensibilidade microbiana e os achados clínico-epidemiológicos em 53 linhagens do gênero Salmonella isoladas de 41 cães, nove equinos e três bovinos, acometidos por diferentes manifestações clínicas entre 1997 e 2007. Salmonella Typhimurium (45,3%), Salmonella enterica (22,6%), Salmonella Enteritidis (7,5%), Salmonella enterica subsp enterica 4,5,12i (5,7%), Salmonella Newport (5,7%), Salmonella Dublin (3,8%), Salmonella Agona (3,8%), Salmonella Glostrup (3,8%), Salmonella Saintpaul (1,8%) foram os sorotipos encontrados. Ciprofloxacina (100,0%), norfloxacina (100,0%) e gentamicina (100,0%) foram os antimicrobianos mais efetivos, enquanto a maior resistência das linhagens foi observada para ceftiofur (28,5%) e florfenicol (7,0%). As linhagens foram isoladas de animais com enterite, infecção do trato urinário, septicemia, piometra, pneumonia e conjuntivite. Ressalta-se para o predomínio do sorovar Typhimurium nas diferentes manifestações da salmonelose nos animais. Destaca-se, também, a identificação de sorotipos nos animais que também são observados em casos de salmonelose em humanos

Published: April 2010

O presente artigo baseia-se num estudo efectuado no âmbito do projecto de investigação Knowandpol sobre as políticas de autonomia e gestão escolar em Portugal, no período ente 1986 e 2009. O objectivo central da pesquisa incidiu na articulação entre conhecimento e acção pública e desenvolveu-se através das seguintes dimensões analíticas: os actores (mapa social e cognitivo); as ideias e sua evolução; a estruturação do campo político pelo conhecimento. No presente artigo irei apresentar alguns dos pressupostos teóricos que orientaram a pesquisa realizada, as características principais da política em estudo, a metodologia utilizada na sua análise e, finalmente, as principais conclusões obtidas a partir dos dados recolhidos.
Governando a educação pelo espelho do perito: uma análise do pisa como instrumento de regulação
Authors: Carvalho Luís Miguel
Published: April 2010

Este artigo analisa o Programme for International Student Assessment (PISA), desenvolvido sob a égide da OCDE, como um instrumento baseado e gerador de conhecimento que participa na coordenação da acção pública no sector educativo. O texto retoma as análises desenvolvidas numa pesquisa sobre a fabricação supranacional do Programa PISA, realizada no âmbito de um projecto de investigação europeu acerca do papel do conhecimento nas políticas públicas de educação e saúde na Europa - Knowandpol. Equacionando o PISA - em suas actividades de inquirição, organização e publicação - como um complexo processo de construção de um espaço de regulação política transnacional, o artigo analisa os elementos cognitivos e normativos do instrumento relacionados com a definição da "realidade educacional", com a determinação das formas "apropriadas" ao seu governo, e com a produção de conhecimento para a política.
O direito à educação e as dinâmicas de exclusão na América Latina
Authors: Gentili Pablo
Published: April 2010

O presente artigo analisa o complexo processo de produção social da exclusão e seus efeitos no direito à educação. O autor descreve e interpreta três dinâmicas que interferem na realização desse direito nos países da América Latina e no Caribe: a pobreza e a desigualdade estruturais; a segmentação e a diferenciação dos sistemas nacionais de educação; e os sentidos que assume o direito à educação, numa cultura política marcada pelo desprezo aos direitos humanos e pela redução do valor da escolaridade aos efeitos que ela tem na concorrência pelos melhores postos no mercado de trabalho. O texto propõe redefinir a radicalidade do direito à educação como um direito humano fundamental, base para a construção de sociedades mais justas e igualitárias.
Mídia-educação: conceitos, história e perspectivas
Authors: Bévort Evelyne , Belloni Maria Luiza
Published: April 2010

Para que a sociedade da informação seja uma sociedade plural, inclusiva e participativa, hoje, mais do que nunca, é necessário oferecer a todos os cidadãos, principalmente aos jovens, as competências para saber compreender a informação, ter o distanciamento necessário à análise crítica, utilizar e produzir informações e todo tipo de mensagens. Esta convicção inspirou este artigo, cujo objetivo é apresentar algumas tendências atuais da mídia-educação no mundo, seus conceitos e ações, buscando contribuir para seu desenvolvimento no Brasil. Mídia-educação é importante porque vivemos num mundo onde as mídias estão onipresentes, sendo preciso considerar sua importância na vida social, particularmente no que diz respeito aos jovens. Promover a mídia-educação é importante também porque as defasagens, que separam muitas vezes os sistemas educacionais do mundo que nos rodeia, prejudicam a formação das novas gerações para a vida adulta.
Educação para a mídia: propostas europeias e realidade brasileira
Authors: Zanchetta Jr Juvenal
Published: April 2010

Partindo-se do estudo das práticas relacionadas à educação para a mídia propostas no cenário europeu, este ensaio observa a possibilidade de inserção dessas práticas no cenário brasileiro. Discutem-se o kit de educação para a mídia, sugerido pela UNESCO, e propostas sobre esse tema em evidência na França, Espanha, Portugal e Inglaterra. O objetivo é mostrar que, embora as sugestões europeias dialoguem com boa parte das idéias prestigiadas no Brasil, por tratarem de um contexto diverso, elas tendem a dificultar o tratamento de questões essenciais a um programa de trabalho sobre mídia na escola brasileira.

Ressaltam-se também as repercussões desse modelo na organização administrativa da escola, que passa a ser caracterizada como democrática, participativa e descentralizada. O objetivo do texto é despertar no leitor a necessidade de atentar para o significado mais profundo das mudanças na forma de administrar a educação e a escola, especialmente a partir dos anos de 1990.
Educação, formação cultural e pluralidade de perspectivas, entre outros (en)cantos das sereias
Authors: Ourique Maiane Liana Hatschbach , Trevisan Amarildo Luiz
Published: April 2010

O trabalho discute a relação unidade-pluralidade a partir da proposta formativa, considerando o contexto de crise da educação. A partir dos novos contornos da razão, adquiridos com a virada linguística, a pesquisa norteia-se pela pergunta: Ainda é possível manter o discurso da formação (Bildung) no contexto de pluralidade das perspectivas contemporâneas que perpassam a educação? Com a destranscendentalização da razão, os fins pedagógicos relacionam-se diretamente com a forma de compreender o conhecimento e o sujeito na educação. A crise do conceito de formação, e seus reflexos no ambiente pedagógico, permite entender o próprio projeto da formação como plural. Dessa maneira, retira-se o conceito de Bildung do aprisionamento ao mastro da embarcação que conduz à universalidade totalitária, para compreendê-lo, também, no exercício das múltiplas possibilidades emergentes dos (en)cantos das sereias.
70 anos do curso de pedagogia no Brasil: uma análise a partir da visão de dezessete pedagogos primordiais
Authors: Cruz Giseli Barreto da
Published: April 2010

A partir da visão de dezessete pedagogos primordiais, levantou-se características do início do Curso de Pedagogia e das mutações por ele experimentadas. Levantou-se, ainda, a visão predominante acerca da pedagogia enquanto domínio de conhecimento e processo de formação, para discutir a sua posição no contexto do campo acadêmico. Os participantes foram escolhidos intencionalmente, com critérios e perfis predefinidos, no sentido de assegurar a composição de um grupo representativo dos primórdios do curso e do campo da educação no Brasil. A abordagem metodológica recaiu sobre a análise de depoimentos colhidos através de entrevistas semiestruturadas. Da análise emergiram aspectos que apontam para a forma como o curso veio se construindo entre nós e para a posição conflituosa, porém importante, que foi ocupando no âmbito do espaço acadêmico da educação.

Published: April 2010

Com o propósito de fomentar o debate em universidades e escolas brasileiras, abordaremos, neste artigo, possíveis significados da pesquisa na prática docente. Trazemos para a discussão perguntas, tais como: quais os possíveis significados da pesquisa na prática docente? Quais as dificuldades e os desafios, em nosso país, para a realização da investigação na escola pelos próprios profissionais que lá trabalham? Qual a relevância desse tipo de pesquisa para a introdução de inovações no currículo escolar e para a formação docente? Ainda em termos da formação, não seria o enfoque na pesquisa mais uma escolha arbitrária que estaria negando outras possibilidades formativas também relevantes?
