Authors: Wang Lu , Wang Bao‐Lei , Wei Zun‐Zheng , Du Qing‐Zhang , Zhang De‐Qiang , Li Bai‐Lian
Published: August 2012

• Premise of the study: Microsatellite markers within regulators of heat stress transcription factors were identified in the Populus trichocarpa genome, and then developed for P. simonii to investigate the genetic diversity of germplasm resources and to further identify favorable alleles significantly associated with stress‐resistant traits.

• Methods and Results: Thirty‐five novel microsatellite markers were identified from genes controlling heat stress transcription factors in P. simonii using a Sanger sequencing protocol. Polymorphisms in 48 individuals from 16 populations of P. simonii revealed that the number of alleles per locus ranged from two to nine with an average of 4.6; the observed heterozygosity and expected heterozygosity per locus varied from 0.143 to 0.857 and from 0.257 to 0.948, respectively.

• Conclusions: The new polymorphic markers developed during this study will facilitate the construction of genetic linkage maps and will aid in marker‐assisted breeding of a new germplasm with desirable abiotic stress resistance in Populus species.
Research-Based Guidelines for Juvenile Justice Programs
Authors: Howell James C. , Lipsey Mark W.
Published: August 2012

Juvenile justice systems make use of many programs intended to reduce the recidivism of the juvenile offenders with whom they interact. Not all such programs are effective and one of the more progressive reforms of recent years has been the movement toward programs validated by research evidence. Three ways to define evidence-based programs are described, with a focus on a relatively unfamiliar approach—evidence from meta-analysis of evaluation research that supports the effectiveness of many generic types of programs. In contrast to the prevailing model program approach, this approach makes use of evidence that supports the effectiveness of many of the homegrown and local programs that juvenile justice systems use. The findings of a large meta-analysis of hundreds of studies reveal that many of these more generic programs are as effective as comparable model programs. These findings have been operationalized into a rating scheme based on the characteristics of effective interventions that can be used by service providers and juvenile justice systems to assess their programs. Two recidivism studies provide promising indications of the validity of this scheme for identifying effective programs and guiding improvement for ineffective ones. The results of this work show that the large body of research on interventions with juvenile offenders can be used to create guidelines that extend the concept of evidence-based programs to the kinds of generic programs most commonly used in juvenile justice systems.
Lacan's dismanteling of his clinic
Authors: Allouch Jean
Published: August 2012

Distinguée par Michel Foucault sous le nom de « fonction psy », la prégnance du discours psychologisant dans la cité est désormais d’une emprise telle en Occident qu’il apparaît presque naturel que le pouvoir, quel qu’il soit, s’adresse aux supposés détenteurs de ce discours lorsque vient au jour une question dite « de société ». On indique qu’à cet endroit le psychanalyste, lui en tout cas, ne peut que s’abstenir. Également qu’une telle abstention est interne à son exercice ; elle y prend ses racines dans un refus actif, quand il s’agit d’accueillir quelqu’un, d’user de quelque grille nosographique que ce soit, autrement dit de cataloguer.
Sexuality and disfiguration: from 19th century medical theories to psychoanalytic's infantile sexual theories
Authors: Linhares Andréa
Published: August 2012

La littérature médicale du début du XIXe siècle établissait de façon récurrente un lien entre anatomie et préférences sexuelles. Selon nombre de médecins de cette époque, l’idée de la défiguration corporelle était articulée à des pratiques sexuelles déviantes. Elle était tantôt envisagée comme la cause des désirs interdits, tantôt comme la conséquence physique visible des rapports sexuels illicites. Ces conceptions historiques du corps et du sexe peuvent-elles apporter un éclairage sur certaines expériences recueillies dans la clinique analytique ? Tel est le pari de cet article. En effet, dès lors qu’elles se réfèrent aux désirs refoulés, du moins socialement, ces théorisations anatomo-pathologiques peuvent fonctionner comme un terrain privilégié pour le déploiement des fantasmes inconscients. Chez les médecins du XIX e siècle, l’idée de la défiguration venait rendre visibles les traces des pratiques sexuelles qui devaient rester invisibles en société (masturbation, pédérastie et saphisme). De la même manière, certaines situations cliniques laisseraient penser que le fantasme de défiguration vient donner une forme corporelle à des positions psychiques angoissantes, de par leur contenu sexuel refoulé. Comme si, afin d’être circonscrits et contenus, l’excès et le désordre pulsionnels du retour du refoulé appelaient la construction psychique d’une figure du corps.
In praise of subjectivity in psychiatry
Authors: Dimitriadis Yorgos
Published: August 2012

La subjectivité du malade est systématiquement méconnue par la médecine depuis surtout qu’elle est devenue scientifique – à savoir depuis le début du XIXe siècle. La psychiatrie doit être, encore plus que le reste de la médecine, orientée vers le sujet malade plutôt que vers la maladie, mais l’exigence de scientificité la pousse de plus en plus vers l’exclusion de la subjectivité, tant celle du malade que celle du clinicien. De nos jours, le sujet est de plus en plus confondu avec son cerveau, et tout un discours neuroscientifique infiltre notre façon d’apercevoir l’individualité et notre rapport à la jouissance. La psychiatrie, même dans ses applications biologiques, doit tenir compte du fait que l’homme est un être parlant, ce qui signifie qu’il entretient un rapport particulier à son corps qui, par conséquent, est « dénaturalisé » ; de ce fait, le sujet ne saurait être confondu avec son cerveau.
Destins du corps et subjectivité dans une clinique sociale

Ce texte étudie trois temps logiques de la réinsertion sociale et surtout psychique à partir d’une pratique de clinique de rue : le premier temps recouvre l’espace de la rencontre dans la rue sur deux ans, le deuxième temps est celui de l’après-rue, temps au cours duquel émergent les points traumatiques suivis d’éventuelles décompensations, le troisième temps est celui où les sujets s’apaisent et se mettent à élaborer des demandes, en l’occurrence celles de comprendre ce qui les a menés dans la rue. L’objectif de ce texte est de construire une position clinique possible dans ces lieux (de) l’extrême.

Résumé Les trajectoires professionnelles sont rarement linéaires et nombre de changements ou de réorientations souvent importants doivent être réalisés par une personne au cours de sa vie active. Une transition professionnelle est toujours un moment délicat à vivre, chargé d’imprévus et de stress. À la lumière de ce que font les rugbymen professionnels français, amenés à devoir se reconvertir du fait de l’arrêt précoce de leur carrière sportive, cet article montre que la maîtrise d’un changement de carrière ou d’une transition professionnelle doit s’appuyer sur trois grandes capacités, soit celles de se réinventer, de se définir un projet de reconversion et de se créer des occasions. Il importe aussi d’acquérir trois compétences clés : développer sa connaissance de soi, son capital humain et son capital social. Sur le plan des attitudes, il faut se montrer proactif et se projeter dans l’avenir et ne pas hésiter à utiliser les programmes et les sources d’aide à la réorientation de carrière.

Résumé Malgré le fait que les femmes ont accès à l’éducation depuis plusieurs décennies, y compris aux meilleures et aux plus prestigieuses écoles et universités, elles éprouvent toujours plus de difficultés que les hommes tout au long de leur carrière, comme si elles avaient à traverser un labyrinthe. De plus, elles atteignent rarement des postes de direction en raison de divers facteurs structurels et culturels qui agissent comme un plafond de verre. Afin de mieux comprendre ces phénomènes, de les contrer ou de les atténuer, cet article présente une synthèse des principaux obstacles auxquels se heurtent les femmes dans leur carrière et donne par la suite des conseils à l’intention des femmes cadres et des organisations.

The molluscan assemblages inhabiting the leaves and rhizomes of a deep water Posidonia oceanica settlement in the central Tyrrhenian Sea
Authors: Albano Paolo G. , Sabelli Bruno
Published: August 2012

The molluscan assemblages inhabiting the leaf and rhizome layers of Posidonia oceanica were studied in a deep water (–24/26 m) settlement of a highly heterogeneous substratum on an off-shore reef in the central Tyrrhenian Sea. This is one of the few works dealing with the rhizome layer and with Posidonia oceanica that has settled on hard substrata. The leaf assemblage only had a few species, less than other assemblages at a comparable depth in the same basin. This poorness may be due to the depth, but it may also be due to the high fragmentation of the meadow. However, the high percentage of carnivores is consistent with previous observations in deep water meadows. The rhizome assemblage is highly diverse both in terms of species and feeding guilds, which could be explained by the higher affinity for low light conditions of most molluscs and the greater habitat heterogeneity. The marked differences in the two taxocoenoses and the high diversification of the rhizome assemblage evidence that they should be included in studies on the potential diversity of Posidonia oceanica meadows. Failure to consider this layer seriously affects any evaluation of the biodiversity of this habitat, which is of great conservation interest.
Description of a new genus of Cryptochiridae (Decapoda: Brachyura) associated with Siderastrea (Anthozoa: Scleractinia), with notes on feeding habits
Authors: Badaro Marcelle F.S. , Neves Elizabeth G. , Castro Peter , Johnsson Rodrigo
Published: August 2012

Members of the Cryptochiridae are small gall-crabs that live as obligate symbionts of scleractinian corals. Only two species have so far been recorded in the western Atlantic Ocean. Herein a new Cryptochiridae genus and species is described, and new information is added on the life history of cryptochirids. The new genus is characterized by having the carapace with the lowest deflection angle among the genera, and also shows the following features: thoracic sternite 4 with setules and constriction smaller than half of the width of the basis, anterior margin curved with apical row of granules; third maxilliped with subcircular exopod reaching medially the lateral margin of the ischium; pereiopod 2 with prominent distomesial and anterolateral expansion on the merus, propodus almost twice larger than dactylus; thoracic sternite 7 with complete medial suture, female pleopod 3 uniramous with longitudinal opening. Male first pleopod straight with subdistal curvature of approximately 90°. Individuals belonging to the new genus are found in galls in massive corals although this structure is cited as being characteristic of ramified corals. The long plumose setae of the maxilliped 3 suggest a filter-feeding function, but the toothless chelae suggest that they are used to gather mucus.

Gradients of the sphingolipid sphingosine-1-phosphate (S1P) are responsible for the egress of lymphocytes from lymph nodes by activating the S1P1 receptor expressed on the surface of lymphocytes. Small molecule drugs that downregulate S1P receptors induce the sequestration of lymphocytes within lymph nodes, thus preventing lymphocytes from accessing sites of inflammation. In particular, FTY720, a pan-S1P receptor agonist, has been efficacious in the treatment of multiple sclerosis as well as its animal model, experimental autoimmune encephalomyelitis (EAE), by virtue of its ability to restrain lymphocytes within the lymph nodes, thus precluding their migration into the CNS. However, multiple leukocyte subsets express S1P receptors of varying types, and although it is beneficial to prevent transmigration of proinflammatory lymphocytes into the CNS, allowing access of regulatory leukocyte subsets to the CNS is desirable. In this study, we show that an S1P1-specific agonist (AUY954) is clinically efficacious in ameliorating pre-established EAE in SJL/J mice. Efficacy of AUY954 correlated with a reduction of lymphocytes in the CNS, but access of plasmacytoid dendritic cells (pDCs) to the CNS was unimpaired, and the presence of pDCs was found to be an important cofactor in mediating the clinical efficacy of AUY954. These results indicate that pDCs are important in quieting autoimmune responses during EAE, and that trafficking inhibitors that are permissive for pDC accumulation in the CNS may be of therapeutic value for the treatment of multiple sclerosis.
IRF4 Promotes Cutaneous Dendritic Cell Migration to Lymph Nodes during Homeostasis and Inflammation
Authors: Bajaña Sandra , Roach Kimberly , Turner Sean , Paul Jinny , Kovats Susan
Published: August 2012

Migration of resident dendritic cells (DC) from the skin to local lymph nodes (LN) triggers T cell-mediated immune responses during cutaneous infection, autoimmune disease, and vaccination. In this study, we investigated whether the development and migration of skin-resident DC were regulated by IFN regulatory factor 4 (IRF4), a transcription factor that is required for the development of CD11b+ splenic DC. We found that the skin of naive IRF4−/− mice contained normal numbers of epidermal Langerhans cells (eLC) and increased numbers of CD11b+ and CD103+ dermal DC (dDC) populations, indicating that tissue DC development and skin residency is not disrupted by IRF4 deficiency. In contrast, numbers of migratory eLC and CD11b+ dDC were significantly reduced in the cutaneous LN of IRF4−/− mice, suggesting a defect in constitutive migration from the dermis during homeostasis. Upon induction of skin inflammation, CD11b+ dDC in IRF4−/− mice did not express the chemokine receptor CCR7 and failed to migrate to cutaneous LN, whereas the migration of eLC was only mildly impaired. Thus, although dispensable for their development, IRF4 is crucial for the CCR7-mediated migration of CD11b+ dDC, a predominant population in murine and human skin that plays a vital role in normal and pathogenic cutaneous immunity.
IL-2 and IL-7 Determine the Homeostatic Balance between the Regulatory and Conventional CD4+ T Cell Compartments during Peripheral T Cell Reconstitution

Published: August 2012

Work over the last decades has led to the identification of the factors that influence the survival and homeostasis of conventional T cells. IL-7 and TCR signaling promote the survival of naive CD4+ and CD8+ T cells in lymphoreplete mice and their proliferation in a lymphopenic environment, whereas survival and homeostatic proliferation of memory CD4+ and CD8+ T cells crucially depend on a combination of IL-7 and IL-15. In contrast, there is little information regarding the factors driving the proliferation of regulatory CD4+ T cells in response to lymphopenia. In this study, we investigated whether regulatory CD4+ T cell proliferation in response to lymphopenia was guided by classical homeostatic resources, such as IL-2, IL-7, or TCR–MHC interactions. Altogether, our data suggest that, although homeostatic proliferation of conventional naive CD4+ T cells is closely related to IL-7 levels, the proliferation of regulatory CD4+ T cells in response to lymphopenia appears to be primarily controlled by IL-2. The capacity of IL-7 to augment conventional T cell proliferation with minimal concomitant regulatory T cell expansion may be clinically exploitable in the treatment of patients with lymphopenia, especially in the case of chronic viral diseases or cancer immunotherapy.

Systemic lupus erythematosus (SLE) is a chronic, multiorgan inflammatory autoimmune disorder associated with high levels of circulating autoantibodies and immune complexes. We report that passive transfer of human SLE sera into mice expressing the uniquely human FcγRIIA and FcγRIIIB on neutrophils induces lupus nephritis and in some cases arthritis only when the mice additionally lack the CD18 integrin, Mac-1. The prevailing view is that Mac-1 on macrophages is responsible for immune complex clearance. However, disease permitted by the absence of Mac-1 is not related to enhanced renal immune complex deposition or in situ C1q/C3 complement activation and proceeds even in the absence of macrophages. Instead, disease is associated with increased FcγRIIA-induced neutrophil accumulation that is enabled by Mac-1 deficiency. Intravital microscopy in the cremasteric vasculature reveals that Mac-1 mitigates FcγRIIA-dependent neutrophil recruitment in response to deposited immune complexes. Our results provide direct evidence that human SLE immune complexes are pathogenic, demonstrate that neutrophils are primary mediators of end organ damage in a novel humanized lupus mouse model, and identify Mac-1 regulation of FcγRIIA-mediated neutrophil recruitment as a key step in development of target organ damage.

Published: August 2012

Sensitization to fungi, such as the mold Aspergillus fumigatus, is increasingly becoming linked with asthma severity. We have previously shown that lung responses generated via the β-glucan receptor Dectin-1 are required for lung defense during acute, invasive A. fumigatus infection. Unexpectedly, in an allergic model of chronic lung exposure to live A. fumigatus conidia, β-glucan recognition via Dectin-1 led to the induction of multiple proallergic (Muc5ac, Clca3, CCL17, CCL22, and IL-33) and proinflammatory (IL-1β and CXCL1) mediators that compromised lung function. Attenuated proallergic and proinflammatory responses in the absence of Dectin-1 were not associated with changes in Ido (IDO), Il12p35/Ebi3 (IL-35), IL-10, or TGF-β levels. Assessment of Th responses demonstrated that purified lung CD4+ T cells produced IL-4, IL-13, IFN-γ, and IL-17A, but not IL-22, in a Dectin-1–dependent manner. In contrast, we observed robust, Dectin-1–dependent IL-22 production by unfractionated lung digest cells. Intriguingly, the absence of IL-22 alone mimicked the attenuated proallergic and proinflammatory responses observed in the absence of Dectin-1, suggesting that Dectin-1–mediated IL-22 production potentiated responses that led to decrements in lung function. To this end, neutralization of IL-22 improved lung function in normal mice. Collectively, these results indicate that the β-glucan receptor Dectin-1 contributes to lung inflammation and immunopathology associated with persistent fungal exposure via the production of IL-22.

The purpose of this article is to emphasize the use of Cone Beam Computed Tomography (CBCT) for root canal treatment. Two case reports are presented where CBCT has been used to locate and eventually treat extra canals in maxillary first molars. Dental clinicians should be aware of the anatomical variations in maxillary molars. CBCT should be an essential part of the diagnosis prior to initiating root canal treatment.
Imaging in the Diagnosis of Cemento-Ossifying Fibroma: A Case Series
Authors: Mithra R , Baskaran Pavitra , Sathyakumar M
Published: August 2012

Cemento-ossifying fibroma is a benign fibro-osseous lesion belonging to the same category as fibrous dysplasia and cementifying dysplasia. These are slow-growing lesions that are seen in the third and fourth decades of life. Both the ossifying fibroma and cemento-ossifying fibroma represent two extremes of the same disease process since histologically both contain bone and cementum. However, the term cemento-ossifying fibroma is justified on the basis of clinical and radiological correlation. Radiographs have become an essential tool in the diagnosis of lesions in the jaw, where the anatomy is complex. Nowadays, CT provides information for diagnosis as well as treatment planning. In this case series, we report three cases of cemento-ossifying fibroma that were histologically confirmed and discuss the imaging findings.

To the best of our knowledge, a portal vein aneurysm presenting with obstructive jaundice has not been reported in the literature. The preferred treatment for these aneurysms is surgical and a shunting procedure should be considered in cases with portal hypertension to preserve portal vein flow when portal hypertension is present or is secondary to the aneurysm itself. In our case, due to patient's advanced age and co-morbidities, an endoscopic biliary stent was placed which led to successful resolution of symptoms of obstructive jaundice.

Velasco, J. L., Rozas, H. S., Echeverría, H. E. and Barbieri, P. A. 2012. Optimizing fertilizer nitrogen use efficiency by intensively managed spring wheat in humid regions: Effect of split application. Can. J. Plant Sci. 92: 847–856. Efficient N fertilizer management is critical for the economical production of wheat and the long-term protection of the environment. Six experiments were conducted at three locations in the south-east of the province of Buenos Aires (SE), Argentina, during a 4-yr period, on Typic Argiudoll and Petrocalcic Paleudoll. The study was designed to evaluate the effects of splitting nitrogen (N) fertilizer on N use efficiency (NUE) in wheat (Triticum aestivum L.). Rates of 0 to 150 kg N ha−1were used, applied at tillering (Z24) or split between Z24 and flag leaf (Z39). The experimental design was a randomized complete block with three replications. Grain yield ranged from 3522 to 8185 kg ha−1, according to N availability and application time. In the experiments without water stress (three out of six), average grain yield (across experiments) was 6669 and 6989 kg ha−1for full and split fertilization, respectively. In four out of six experiments, average N in above-ground biomass (NAB), N recovery fraction (NRF), and grain protein content (GPC) for split N application were greater than for full N at Z24 (NAB, 176 and 157 kg N ha−1; NRF, 66 and 51%; GPC, 100 and 92 g kg−1, for split and full N application, respectively). In years without water stress, splitting N between Z24 and Z39 is an appropriate strategy to improve NRF, reducing N losses, and minimizing the environmental impact of fertilization.

Wang, H.-W., Hu, H.-X., Song, T.-M. and Chen, S.-J. 2012. Seed traits evaluation from long-term selection of kernel oil concentration in a high-oil maize population KYHO. Can. J. Plant Sci. 92: 857–866. A high-oil maize population, KYHO, was developed over 10 generations by selective breeding for increased kernel oil content (KOC). The objectives of this study were to evaluate kernel oil selection effects, and measure the trait changes and genetic variance in the embryo and endosperm. Oil, protein, and starch content in the embryo and endosperm were estimated by near-infrared reflectance spectroscopy (NIRS). Mass and volume of embryo and endosperm were measured. Selective breeding increased embryo oil content (EMOC) and endosperm oil content (ENOC), especially EMOC, which changed from 315.62 g kg−1C0 to 592.54 g kg−1C10, resulting in an increase in total embryo and endosperm oil content (EEOC) from 43.32 g kg−1C0 to 139.95 g kg−1C10. With selection for increase in EEOC, embryo protein content (EMPC) decreased slightly; however, endosperm protein content (ENPC) and total protein content (EEPC) increased significantly. Embryo and endosperm starch content (EMSC and ENSC) and total starch content (EESC) all decreased substantially with selection. One hundred embryo mass (EMM) was not notably changed with selection, but 100 embryo volume (EMV) increased significantly. Mass and volume of endosperm (ENM and ENV) and total mass and volume of embryo and endosperm (EEM and EEV) all decreased significantly with selection, possibly due to markedly decreased starch content. Linear regression analysis indicated with each 1 g kg−1EEOC increase, EMOC, ENOC, ENPC, EEPC, EMM, and EMV increased 2.74 g kg−1, 0.16 g kg−1, 0.38 g kg−1, 0.36 g kg−1, 0.06 g, and 0.20 mL, respectively, and EMPC, EMSC, ENSC, EESC, EEM, ENM, EEV, and ENV decreased 0.04 g kg−1, 1.48 g kg−1, 0.60 g kg−1, 1.09 g kg−1, 1.26 g, 1.32 g, 0.97 g, and 1.17 mL, rspectively.

Short Communication: Diurnal variations of nonstructural carbohydrates and nutritive value in timothy. Can. J. Plant Sci. 92: 883–887. Nonstructural carbohydrate (NSC) concentration in timothy (Phleum pratense L.) increased during the day by 16 to 41 g kg−1 DM (+23 to 137%) in spring and summer growth cycles and reached a maximum value between 12.8 and 13.2 h after sunrise in an area with 15 to 16 h of day length. This increase in NSC concentration was generally accompanied by a decrease in concentrations of neutral detergent fiber (−2 to 6%), acid detergent fiber (−1 to 7%), and N (−6 to 11%).

Sprengel's sedge (Carex sprengelii) has been documented as a primary graminoid species in riparian woodlands and forested areas of the northern Plains. Currently, there is no documentation of the nutrient content of Sprengel's sedge. The objective of this study was to determine the nutritional value of Sprengel's sedge of riparian woodlands in eastern North Dakota. Plants were clipped to 2.5 cm from the soil surface at 2-wk intervals during the growing seasons of 2009 and 2010. Multiple whole-plant samples were collected from five randomly selected sites at two different locations during each collection period. Plant tissue was analyzed for crude protein (CP), acid detergent fiber, neutral detergent fiber, in vitro organic matter digestibility (IVOMD), calcium, and phosphorus. The CP concentrations declined from over 20% in May to under 10% in October. Sprengel's sedge, based on IVOMD, met energy requirements for a 550 kg lactating cow early in the growing season; however, as the growing season progressed it was unable to meet energy requirements. Irrespective of year, Sprengel's sedge maintains a high CP level throughout a typical grazing season; however, digestible energy becomes deficient. Grazing strategies that promote spring and early summer grazing or supplementation of a high-energy feed source to compensate for the decrease in energy are recommended.
Short Communication: Timing of stinkweed and shepherd's-purse recruitment affects biological characteristics of progeny

The effect of recruitment timing (fall versus spring recruitment) on seed characteristics and performance of two common Canadian facultative winter annual weeds; stinkweed (Thlaspi arvense L.) and shepherd's-purse (Capsella bursa-pastoris L.) was investigated. Seed germination proportion was unaffected by maternal emergence timing but germination was faster for spring versus winter cohort seeds of stinkweed. Proportionally more seeds from winter (fall-recruited) cohorts were rendered non-viable by aging treatments, while for shepherd's purse, aging treatments broke dormancy instead of reducing viability and this was especially true for winter cohort seeds. For both weed species, spring cohort seeds produced earlier flowering plants with greater and lesser biomass allocation to reproductive tissues and roots, respectively. These results show the potential importance of germination timing and maternal effects on weed populations and demonstrate additional complexity in the nature of facultative winter annual weeds, in particular.

Gestión universitaria: un enfoque holístico
Authors: Tamayo Horacio V. Barreda
Published: August 2012

Un breve análisis comparativo de los resultados y características de las universidades en el Perú (Censo Universitario 2010); con referencia a las mejores universidades a nivel internacional (Oppenheimer, 2010). Nos permite alertar a la conciencia nacional, sobre la necesidad de hacer un cambio en la gestión universitaria vigente. De no hacer nada, podemos afirmar que a futuro vamos a estar peor que ahora, porque aumentará la brecha negativa. Para lograr mejores resultados a mediano plazo, se propone un enfoque holístico de la gestión universitaria. El enfoque holístico propuesto, considera dos niveles de gestión, uno a nivel macro y otro a nivel  micro. La macro gestión universitaria vincula los resultados de la educación universitaria con el desarrollo sostenible de cada País y la educación en general. La micro gestión universitaria, es la que debe desarrollarse al interior de cada Institución a nivel funcional.

Authors: Vargas Guiselle María Garbanzo
Published: August 2012

La autora ofrece un replanteamiento de la administración de la educación desde la teoría de la complejidad en el contexto de la sociedad de la información. Se considera vital el repensar la administración de la educación como disciplina y estrategia para alcanzar que las organizaciones educativas en la postmodernidad logren los niveles de competitividad que requieren las demandas de los nuevos tiempos. Se considera impostergable un abordaje y enfoque desde la interdisciplinaridad y la complejidad como visiones epistemológicas en las organizaciones educativas en un mundo globalizado. Los profesionales en el campo de la administración de la educación ante la emergente sociedad de la información requieren un replanteamiento de su rol dentro de las organizaciones educativas, capaces de desarrollar habilidades y competencias para gestar bajo un mundo complejo e incierto, dimensiones a considerar en el presente artículo.

O mercado educacional vive momentos de intensas transformações, principalmente em razão da grande concorrência do setor. O presente artigo tem por objetivo fazer uma análise geral desse mercado, evidenciando a ótica do marketing, sua importância e a necessidade de adaptação à nova economia e suas exigências. Para tal, utilizamos a metodologia da pesquisa bibliográfica e documental. Os resultados apontam para a necessidade de ações estratégicas de marketing, visando ao fortalecimento das Instituições de Ensino Superior – IES na acirrada concorrência existente no setor. Percebemos que, até a bem pouco tempo, grande parte das IES focava seus investimentos em prédios e laboratórios, sem a devida preocupação de identificar as expectativas e desejos dos alunos e as exigências do mercado. Concluímos que a nova realidade exige, hoje, um posicionamento transparente e que a reputação da marca e os valores a ela agregados ganham cada vez mais importância, o que implica no desenvolvimento de ações internas e externas, dentro de uma óptica que classifica o aluno como cliente, não apenas como estudante.

Published: August 2012

A Lei de Diretrizes e Bases da Educação, de 1996, em seu artigo 80 estabeleceu a base legal para a operação da Educação a Distância – EaD em todas as instâncias. A importância desta lei advém da necessidade de se instituir com segurança, estabelecer parâmetros de funcionamento e qualidade e por fim, avaliar os diversos cursos de EaD por ele abrigado. Neste cenário surge a Universidade Aberta do Brasil – UAB como importante política de combate a deficiência na formação do docente nas unidades da Federação mais distantes dos grandes centros, entendendo a qualidade da formação docente é um ponto crítico para as sérias deficiências que assolam a educação básica brasileira. Diante disso, o objetivo do trabalho é analisar a UAB como alternativa de expansão e interiorização da educação, principalmente no tocante à formação docente.

Conectividade na construção de conhecimentos: adequação da grade curricular no curso de engenharia de materiais
Authors: Kuester Scheyla , Pottmaier Daphiny , Machado Andréia de Bem , Alarcon Orestes Estevam
Published: August 2012

A elaboração de uma grade curricular adequada pode ser feita partindo do princípio de que a construção de conhecimentos se dá por um processo de conexão entre saberes distintos em níveis crescentes de complexidade. Partindo do que já se sabe, novos conhecimentos e habilidades podem ser continuamente construídos. No ensino universitário a disposição das disciplinas na grade curricular parecem seguir certa linearidade, porém algumas vezes não ha conectividade entre seus conteúdos. Com base nisto, este artigo buscou levantar a questão da adequação curricular na construção de conhecimentos dentro do curso de Engenharia de Materiais da Universidade Federal de Santa Catarina. Para isso, foram elaborados e aplicados questionários de pesquisa de opinião e de verificação de conhecimentos prévios com os alunos de uma disciplina especifica do curso.  De um modo geral, os dados apontam uma deficiência de conhecimentos prévios elementares por parte dos alunos, o que acaba por resultar em altos índices de reprovação nesta disciplina.
Desafios expressos na missão de treze universidades de Santa Catarina: um olhar externo
Authors: Rieder Arno
Published: August 2012

As Instituições de Educação Superior(IES), em especial as Universidades, são fundamentais para alavancar a prosperidade. Cumprem papéis importantes na promoção do homem, na interação deste em sociedade e no ambiente. Suas missões definem o que fazem, constituído-se de desafios. Os resultados demonstram sua competência em responder aos desafios. Este trabalho objetivou subsidiar e estimular o debate sobre os desafios das Universidades sediadas no Estado de Santa Catarina(SC). Para identificar os desafios assumidos por treze Universidades de SC efetuou-se a análise de suas missões, disponíveis nos textos eletrônicos mantidos pelas instituições, acessadas entre 10-30 de outubro de 2011. Os resultados mostram que o principal desafio de todas as IES é contribuir com o desenvolvimento regional(divergindo em tipos). Outros desafios encarados por algumas universidades são compromissos com: o conhecimento(produção até a aplicação), a formação(cidadã até a especializada), a educação(vários enfoques), a melhoria da qualidade de vida e ambiental, o envolvimento comunitário, estímulo ao empreendedorismo. Entre os vários desafios assumidos por cada universidade apenas um é comum a todos os demais são opções de menos de 2/3 das IES. O eixo comum é a busca do desenvolvimento e os demais eixos são opções sob efeito do contexto temporal e sócio-ambiental regional.

Published: August 2012

Este artigo tem como objetivo apresentar o processo de implantação da Universidade Federal da Fronteira Sul a partir de alguns dos condicionantes de sua implantação (traços de contexto), da concepção delineada de universidade pública, democrática, popular (conceito) e, finalmente, da constituição de sua organização institucional, multicampi e interestadual(desenho institucional). Assim, fica demonstrada a importância da consideração do entorno como peça-chave na construção das políticas e estratégias de uma instituição que nasce a partir das demandas dos movimentos sociais. Visa garantir o acesso ao ensino superior público e de qualidade, a qualificação profissional e o compromisso de inclusão social e o desenvolvimento do ensino, da pesquisa e da extensão como condição de existência de um ensino crítico, investigativo e inovador.  A UFFS busca construir uma estrutura organizacional diferenciada, onde os campi são os órgãos de base e são considerados igualmente importantes, garantindo o mesmo padrão de qualidade para as condições de infraestrutura física e humana no interior de cada campus. A essência é a manutenção do diálogo constante entre as instâncias administrativas, normativas e pedagógicas, entre os órgãos superiores e de base da universidade, onde a autonomia administrativa e pedagógica acontece em todos oscampi da universidade.
