Revistas electrónicas en Ciencias Sociales y Humanidades
Authors: Villalón Panzano J. , Aguillo Caño I. F.
Published: June 2014

Se presenta una revisión de las revistas electrónicas publicadas a través de Internet en el ámbito de las Ciencias Sociales y las Humanidades. Con el objeto de realizar un análisis comparativo se han seleccionado dos muestras, una de carácter global (250 títulos) y otra nacional (50 títulos). Estados Unidos protagoniza la edición electrónica en estas disciplinas, alcanzando e) 71 % del total de títulos analizados, mientras que el inglés es utilizado como idioma principal en el 97,5 % de la muestra. En cuanto a las temáticas cubiertas no existe un claro predominio de unas sobre otras si exceptuamos el caso de las Artes y las Letras (32 % en la muestra española y 27 % en el resto del mundo). El principal agente editorial es la Universidad, responsable del 75 % de los títulos publicados. La calidad formal es alta al haberse comprobado la existencia de comité editorial y proceso de evaluación por pares en un 62 % de los casos españoles y hasta un 78 % de los del resto del mundo. Es relativamente bajo el porcentaje de revistas con ambos tipos de ediciones (papel y electrónica) en el caso español (44 %) frente a la situación mundial donde nos encontramos con un 63 %. Factores económicos podrían explicar tal disparidad.
25 años de teledocumentación en España
Authors: Baiget T.
Published: June 2014

En noviembre de 1998 se han cumplido 25 años de la instalación del primer terminal de teledocumentación o de acceso en línea a bases de datos en nuestro país. El autor recuerda algunos datos históricos y analiza el desarrollo y evolución de esta tecnología, cuya entrada en España tuvo lugar por dos acciones separadas: Una llevada a cabo en 1973 por el INTA (Instituto Nacional de Técnica Aeroespacial), del entonces Ministerio del Aire (actualmente integrado en Defensa) y el desaparecido CIDC (Consorcio de Información y Documentación de Catalunya) con la ayuda de FUNDESCO (Fundación para el Desarrollo de la Función Social de las Comunicaciones) de Telefónica, en 1973. Y otra en 1975, por el CID (Centro de Información y Documentación), actualmente CINDOC (Centro de Información y Documentación Científica), del CSIC (Consejo Superior de Investigaciones Científicas). Finalmente se comenta la evolución de los hosts y la progresiva disolución de las técnicas en línea clásicas en el nuevo contexto de internet.

Conectividad de sistemas, recuperación de información muy estructurada, redefinición de aplicaciones (robots de búsqueda, agentes...), integración con sistemas propietarios, edición online y CD-ROM, protocolos... Sin embargo, en la actualidad se está favoreciendo muy poco el desarrollo de sistemas basados en esta norma. En este artículo se analizan las diversas posibilidades que ofrece la misma.
When the Wisdom of Communication is Vital During the Requirements Elicitation Process
Authors: Ahmad Sabrina , Muda Noor Azilah , Aziz Maslita Abd. , Kasmuri Emaliana
Published: June 2014

Requirements elicitation is accepted as one of the most crucial stages in software engineering, as it addresses the critical problem of designing the right software for the stakeholder. It is seldom technical difficulties that cause problems in the process of requirements elicitation but rather human factors, especially communication. This chapter presents the requirements elicitation experience with the industry and the lessons learnt throughout the process. It highlights the requirements elicitation best practices and alternative options during the process. It also discusses the issues concerning communication disparity between the stakeholders, which may affect the software development project as a whole. The outcome of the requirements elicitation process experience is reported and analysed for future improvement.
An Algebraic Approach for the Specification and the Verification of Aspect-Oriented Systems
Authors: Sabas Arsène , Shankar Subash , Wiels Virginie , Meyer John-Jules Ch. , Boyer Michel
Published: June 2014

Aspect-Oriented (AO) Technology is a post-object-oriented technology used to overcome limitations of Object-Oriented (OO) Technology, such as the cross-cutting concern problem. Aspect-Oriented Programming (AOP) also offers modularity and traceability benefits. Yet, reasoning, specification, and verification of AO systems present unique challenges, especially as such systems evolve over time. Consequently, formal modular reasoning of such systems is highly attractive as it enables tractable evolution, otherwise necessitating that the entire system be re-examined each time a component is changed or is added. The aspect interactions problem is also an open issue in the AOP area. To deal with this problem, the authors choose to use Category Theory (CT) and Algebraic Specification (AS) techniques. In this chapter, the authors present an aspect-oriented specification and verification approach. The approach is expressive and allows for formal modular reasoning.
Back to Basics
Authors: Morien Roy
Published: June 2014

Massive failures of software development projects have been recorded in the literature, and particularly in the popular press, over the years. Yet, rarely if ever have we seen any objective, detailed analysis of the causes of these failures. Indeed, we usually can only surmise how the projects were managed or what the development methodology or approach was. This chapter analyses some aspects of software development projects and development methodologies in terms of the success or failure potential of these methodologies. The conclusion arrived at is that the system development methodologies handed down since the late 1970s as the preferred development approach, generally known as Structured Methodologies, based on the Structured Design Life Cycle methodology (SDLC), bear the seeds of their own failure. It is asserted that they cannot succeed because of the inherent nature and assumptions embedded in those methodologies. After some analysis of these assumptions, considered to be highly flawed and unworkable, the now not so recently published Agile Development methodologies are discussed and proffered as a workable and inherently successful approach to software system development.
Lessons from Practices and Standards in Safety-Critical and Regulated Sectors
Authors: Tuohey William G.
Published: June 2014

Many years of effort have been expended by experienced practitioners and academic experts in developing software engineering standards. Organizations should see it as a positive advantage—rather than as a costly negative necessity—when they are required to develop software to a recognized standard. A genuine, constructive program of measures to ensure compliance with an objective standard will achieve development process improvements that would otherwise be difficult to motivate and bring to fruition. This chapter provides an overview and comparison of a number of software engineering standards specific to safety-critical and regulated sectors. It goes on to describe implications and benefits that flow from these standards. Informed by current software engineering research, suggestions are made for effective practical application of the standards, both at individual project and at organizational level.
Important Issues in Software Fault Prediction
Authors: Abaei Golnoush , Selamat Ali
Published: June 2014

Quality assurance tasks such as testing, verification and validation, fault tolerance, and fault prediction play a major role in software engineering activities. Fault prediction approaches are used when a software company needs to deliver a finished product while it has limited time and budget for testing it. In such cases, identifying and testing parts of the system that are more defect prone is reasonable. In fact, prediction models are mainly used for improving software quality and exploiting available resources. Software fault prediction is studied in this chapter based on different criteria that matters in this research field. Usually, there are certain issues that need to be taken care of such as different machine-learning techniques, artificial intelligence classifiers, variety of software metrics, distinctive performance evaluation metrics, and some statistical analysis. In this chapter, the authors present a roadmap for those researchers who are interested in working in this area. They illustrate problems along with objectives related to each mentioned criterion, which could assist researchers to build the finest software fault prediction model.
Economic Development of a Selected Region
Authors: Myšková Renáta , Linkeová Ivana
Published: June 2014

Macro-economic aspects and further factors influence the economic development of a region. Two new indicators (Index of Citizens' Financial Provision and Risk of Regional Economic Development) are introduced in this paper. These indicators enable people to evaluate the financial provision of citizens and the economic risk of a region in more detail. To demonstrate a function of these new indicators in economic practice, the authors focus on the selected region (Vysocina, Czech Republic) due to the following specific characteristics. Economic performance of the Vysocina Region in comparison with other regions of the Czech Republic is below the average. When calculating GDP per capita the Vysocina Region ranks eleventh position from fourteen regions in the Czech Republic. The input data for examples given in this paper are based from the Czech Statistical Office. Mathematical modeling of the new developed indicators has been created in Microsoft Excel program. To design Indicator Risk of Regional Economic Development the fuzzy sets logic has been used.
Cardiac Diagnostic Testing: What Bedside Nurses Need to Know
Authors: Ramos Lupe M.
Published: June 2014

Coronary artery disease affects more than 385000 persons annually and continues to be a leading cause of death in the United States. Recently, the number of available noninvasive cardiac diagnostic tests has increased substantially. Nurses should be knowledgeable about available noninvasive cardiac diagnostic testing. The common noninvasive cardiac diagnostic testing procedures used to diagnose coronary heart disease are transthoracic echocardiography, stress testing (exercise, pharmacological, and nuclear), multidetector computed tomography, coronary artery calcium scoring (with electron beam computed tomography or computed tomographic angiography), and cardiac magnetic resonance imaging. Objectives include (1) describing available methods for noninvasive assessment of coronary artery disease, (2) identifying which populations each test is most appropriate for, (3) discussing advantages and limitations of each method of testing, (4) identifying nursing considerations when caring for patients undergoing various methods of testing, and (5) describing outcome findings of various methods.
Harlequin Syndrome as a Complication of Epidural Anesthesia
Authors: Boling Bryan , Key Christopher , Wainscott Justin , Rebel Annette
Published: June 2014

Harlequin syndrome is a rare neurological condition that results in unilateral facial flushing and sweating. Although the syndrome is generally a benign condition with complete resolution if appropriate treatment is initiated, unilateral facial flushing can be a sign of several serious conditions and should be thoroughly investigated. Sudden onset of facial flushing related to harlequin syndrome developed in a patient who had bilateral lung transplant with postoperative epidural anesthesia for pain control. Differential diagnosis includes neurovascular disease (acute stroke), malignant neoplasm of brain or lung, Horner syndrome, idiopathic hyperhidrosis, and Frey syndrome. Harlequin syndrome is often easily treated by discontinuing the anesthetic or adjusting placement of the epidural catheter. (Critical Care Nurse. 2014;34[3]:57–61)

Formulating Guidance on Hydrotesting Deepwater Oil and Gas Pipelines
Authors: Kopp Frans , Ayers Ray R.
Published: June 2014

As pipelines are being constructed for ever-deeper water depths, environments are encountered that significantly alter the way pipelines are designed and hydrotested. This paper describes industry-based BASM (best available and safest methodology) guidance to BSEE pertaining to certain alternate procedures and equipment requests from the regulations. These new guideline recommendations pertain specifically to hydrotesting of deepwater pipeline system tiebacks from subsea wells to surface-based floating production systems and deepwater export pipeline and riser systems to downstream facilities under DOI jurisdiction.

This effort was designed to closely involve experts from the Oil and Gas Industry in the development of these Hydrotest Guidelines. The project team conducted two broad-based industry workshops for oil companies, suppliers, and BSEE. The primary objective was to discuss with key industry stakeholders the pros and cons of regulations currently in place, and collect industry advice on currently used and/or recommended deepwater pipeline/riser hydrotesting practices. The resulting guidelines described here were written by a small team of industry-based members, rather than a single individual or organization.

One overriding conclusion from the work is that Alternate Compliance with the requirements for hydrostatic testing as per 30 CFR 250 Paragraph 250.1003(b)(1) should consider using API RP 1111 to define the minimum and actual test pressures at each depth-related location in the pipeline and riser. Additional conclusions were developed and are provided in the paper.

As water depths of new production increase to 10, 000 feet and beyond, both industry and BSEE recognize that current BSEE design and hydrotest requirements as specified in 30CFR 250.1003(b)(1) and BSEE NTL 2009-G28, Pipeline Design, and differences between hydrotesting at the surface vs. at the mudline, and pipeline product fluid pressure gradient must be reconsidered and reformulated because they impact hydrotest methodology.

Authors: Kalman Mark , Yu Liang , Durr Casey , Suarez Jorge
Published: June 2014

This paper presents a process employed to qualify new technology in unbonded flexible pipe in accordance with API Specification 17J, API Recommended Practice 17B, DNV-OS-C501 and DNV-RP-A203. The relevance of each standard in qualifying new pipe layers, pipe structures, and end fitting designs are addressed. New pipe layers include both glass and carbon fiber reinforcement for the pressure armor and tensile armor, and new pipe structures are unbonded flexible pipes that include all composite and hybrid composite/metallic structural layers. The paper focuses on the implementation of DNV-RP-A203 in the qualification process, including the qualification basis, technology assessment, threat assessment, development and execution of the qualification plan with tests based on API 17J and 17B, and the performance assessment.
High Resolution Imaging Using Sea Surface Related Multiples
Authors: Lu Shaoping , Whitmore Dan , Kinkead Jack , Valenciano Alejandro , Martinez Ruben
Published: June 2014

In marine oil and gas exploration of seismic data acquisition, both primary and multiple reflections are recorded at the streamers. In seismic data processing, primaries are usually used as signal to image the subsurface; multiples are regarded as noise to be removed (SRME) (Verschuur, 1991). Multiples can also be treated as useful information to image the earth. The idea of using sea surface related multiples as valuable information for depth migration has been discussed by Berkhout and Verschuur (1994), Guitton (2002) and Whitmore et al. (2010). Lu et al. (2011) presents the first 3D example of imaging sea surface related multiples using towed streamer acquisition geometry.

Conventional shot domain migration constructs a subsurface image by combining the forward extrapolated down-going wavefield from a source location and reverse extrapolated up-going wavefield originating at the surface receiver positions. Similarly, sea surface related multiples can also be used for imaging the subsurface where the boundary data for the down-going and up-going wavefields are generated at the receiver locations via up-down wavefield separation. After up-down separation, the down-going and up-going wavefields act as the source and receiver surface wavefields and exist at the receiver positions.

Compared to primaries imaging, multiples imaging can help to enhance subsurface illumination in depth migration; because the source wavefield (down-going wavefield) of multiples imaging is more broadly distributed than the source wavefield of primaries imaging. More significantly, multiples imaging improves angular illumination by using additional source wavefield coverage.

In this paper, 3D field data examples are used to compare imaging of primaries and imaging of multiples. A shallow water field data example shows the successful application of the technology to mitigate the acquisition footprint and generate very high resolution images. A deep water field data example demonstrates the opportunity of the technology to improving subsurface illumination and angular illumination when applied to wide azimuth acquisition. By enhancing subsurface illumination in depth migration, the technology has the potential of improving quality of subsurface reservoir characterization and reducing drilling hazard risks.
Grand Banks Scour Catalogue (GBSC) GeoDatabase
Authors: Campbell P , Burke E , Sonnichsen G V
Published: June 2014

In the late 1990's and early 2000's, NRCan, through the Geological Survey of Canada (GSC), conducted research on the distribution and severity of seabed iceberg scour on the Grand Banks. One of the key products of that work was a research database that recorded
the location and geometric parameters for all mapped seabed scours on the Grand Banks. The Grand Banks Scour Database (GBSC) was developed under GSC contract to Canadian Seabed Research Ltd. (CSR) and updated sporadically when funding allowed new data to be captured. With the wind-down of GSC work
on Grand Bank seabed scour, it is important to formalize the database and release a standardized database in a documented and publicly accessible format. This report documents the development of a simplified GIS Geodatabase that represents the key scour parameters. The scours recorded in the GBSC
were identified and measured from various geophysical data sets including; sidescan sonar, multibeam sonar, sub-bottom profiler, single beam echo sounder, and high resolution single channel seismic (Huntec) systems. The GBSC survey coverage consists of an irregular network of regional lines (22,704
km) and site surveys (4762 km2) conducted by the GSCA and the petroleum industry. The simplified GBSC Geodatabase compiled during this study contains 5366 iceberg furrow features and 2680 iceberg pit features. The interaction of ice and seafloor sediments may result in a variety of ice scour types
and shapes. Features stored in the GBSC include furrows, furrows with an associated pit (s), individual pits and Pit Chains. Iceberg furrows and pits have been recorded in water depths ranging from 49 to 350 m and within sediment types of Predominantly Sand, Sand & Gravel, and Gravel.
Although a significant number of furrows occur within each 10° orientation bin the general orientation mode of the GBSC furrow population is northeast - southwest. Furrow length ranges from 5 m to 10,216 m, with a mean length of 584.7 m while Pit area ranges from 84 m² to 111,300 m²,
with a mean area of 6193 m². Furrow width measurements range from 1 to 208 m with a mean width of 26 m. Furrow depth ranges from 0.1 m to 7.0 m, with a mean depth of 0.88 m while Pit depth ranges from 0.1 m to 8.3 m, with a mean of 1.92 m.
Emplaced writing figuring as a manifestation of an ecocentric mindset in the narrative art of Petra Müller
Authors: Meyer Susan
Published: June 2014

The human-earth connection is a sustained theme in Petra Müller’s oeuvre. The article focuses on this connection as reflected in her narrative art, specifically in accounts that have an autobiographical proclivity. The aim of this article is to outline the nature-centred disposition of Müller’s narrative art in a more definite sense. This is achieved by paying attention to the manner in which the author (the ‘I’ in accounts where the narrator can be identified as the author herself) becomes part of the natural environment – whether on a sensory, an emotive, or an intellectual level – where she finds herself and the way she responds to it. At the core of the investigation are the ways in which this reactive engagement is manifested in Müller’s prose work by the implied author and the technique ofemplaced writing. Emplaced writing, a concept created by Linda Russo, was integrated by Susan Smith with Lawrence Buell’s concept of emplacement. This term refers to the technique allowing an active awareness of self and the place physically occupied by the author, as well as how that body fits into this place, to find expression. A broader perspective and greater appreciation of Müller’s work are drawn from the insight into how her close coexistence with the earth is reflected in her narrative art by means of the technique of emplaced writing which is explored in this article as it gives voice to a strong ecocentric disposition.
Importance of early and deeper responses to long-term survival in CML patients: Implications of BCR-ABL testing in management of CML in Indian setting
Authors: Agarwal Mohan B.
Published: June 2014

The prognosis of patients with chronic myeloid leukemia (CML) has changed radically since the advent of imatinib mesylate, a selective inhibitor of BCR-ABL tyrosine kinase. Shortly thereafter, more potent BCR-ABL inhibitors (dasatinib and nilotinib) were introduced for use in patients resistant to or intolerant of imatinib. All three drugs are now approved for initial therapy for chronic phase CML. Response to tyrosine kinase inhibitor (TKI) treatment is assessed with standardized quantitative reverse transcriptase polymerase chain reaction (Q-RTPCR) and/or cytogenetics at 3, 6 and 12 months. Clinical trials have clearly demonstrated that early and deeper cytogenetic and molecular response to TKI therapy is associated with lower rate of disease progression and improved long-term outcomes. In recent times, molecular response as determined by BCR-ABL transcript levels at defined time points is rapidly gaining popularity as a predictive marker for subsequent outcomes in CML. Optimal response is defined as BCR-ABL transcript levels of ≤10% at 3 months, <1% at 6 months, and ≤0.1% from 12 months onward while >10% at 6 months and >1% from 12 months onward define failure. Patients who do not achieve molecular milestones at 3 or 6 months with 3 months being highly predictive are less likely to achieve cytogenetic responses eventually; early identification of such patients who have a low probability of achieving an adequate response are thus candidates for alternative treatment. Review of literature by electronic search of MEDline, Google Scholar was done using keywords and data was identified and systematically evaluated.

Authors: Olukayode A Olukayode , Richard I , Rachael A Rachael , Babajide O Ireti , Ireti O Gbolahan , Gbolahan O
Published: June 2014

Context: Abnormal abdominal distension in a child is usually a source of great concern and apprehension in both the parents and the pediatric surgeon. Although Wilms′ tumor is the most common malignant abdominal childhood tumor, usually causing abdominal distension, many other less common causes can also result in abdominal distension. Therefore, early diagnosis of Wilms′ tumor and distinguishing it from all these other causes is essential. Aims: We intend to document the pattern of computed tomography (CT) scan findings in patients with Wilms′ tumor and the peculiarity of its radiological presentation in this environment, highlighting its accuracy and advantages over other imaging modalities. Settings and Design: This is a prospective descriptive study conducted between January, 2011 to January 2012, where all infants, 6-96 months of age, who were suspected to have Wilms′ tumor were made to undergo CT scan examination as part of their management work-up. It was carried out in a teaching hospital. Subjects and Methods: The study performed on 12 children age range of 6-96 months old underwent abdominal CT scans as part of their clinical work-up using a GE Hi-speed dual CT scanner ® . Pre- and post-contrast images were acquired and assessed by the radiologists. They were operated and their radiological and histopathology results were correlated. Statistical Analysis: All data was entered into a Microsoft word excel spread sheet and analyzed by simple analysis. Percentages and proportions were determined for categorical variables. Results: Of the 12 patients seen, nearly 75% were males, with a male to female ratio of 3:1 and an average age of 37 months. The right sided tumors were slightly more than the left and nearly 25% were bilateral. Approximately 17% showed punctuate calcifications. Heterogeneous contrast enhancement was seen in all the cases, vascular encasement in three and lymphadenopathy in six cases. There was no bony involvement in any of them but 75% of the masses seen, crossed the midline. Histological confirmation of Wilms′ tumor was obtained in all cases. Conclusions: Majority of the tumors seen in this study crossed the midline and a few of them showed calcification. CT scan is relevant and accurate in investigating children with Wilms′ tumor as it reveals concomitant lesions with involvement of the abdominal vessels and lymph nodes.

Authors: Kumar D. Santhosh , Noronha Vanita , Joshi Amit , Jain Hasmukh , Prabhash Kumar
Published: June 2014

Carcinomatous meningitis or meningeal carcinomatosis is seen in up to 5% of patients of metastatic non-small cell lung cancer. However, isolated carcinomatous meningitis without brain parenchymal metastasis is less common. Patients with carcinomatous meningitis have limited treatment options. However, intrathecal therapy if used optimally along with targeted therapy when indicated result in good palliation with improvement in survival.
Non-Hodgkins lymphoma with lactic acidosis at presentation: A case report of a rare oncologic emergency
Authors: Kumar Arvind , Raina Vinod
Published: June 2014

Lactic acidosis (LA) has been reported to be associated with high grade lymphoma as a terminal event. Its causes are multi-factorial. It can either occur due to overproduction of lactic acid by rapidly dividing tumor or due to its underutilization due to involvement of liver by lymphomatous deposits. The prognosis of lymphoma associated with LA is dismal. We present a patient of non-Hodgkins lymphoma (NHL) who presented with LA, after an initial response succumbed.
Primary anaplastic astrocytoma of the brain after prophylactic cranial irradiation in a case of acute lymphoblastic leukemia: Case report and review of the literature
Authors: Ahmed Imtiaz , Krishnamurthy Sapna , Kakkar Aanchal , Julka Pramod Kumar , Rath Goura Kishor
Published: June 2014

A 6½-year-old boy had developed acute lymphoblastic leukemia and was treated with systemic chemotherapy, intrathecal triple drug regimen and prophylactic cranial irradiation. After 10 years he developed anaplastic astrocytoma of the postero-superior cerebellum on the left side while leukemia was in remission. He was treated with surgical excision, followed by adjuvant three dimensional conformal radiotherapy and is on salvage chemotherapy with temozolamide. It is possible that the anaplastic astrocytoma may be a radiation induced malignancy.

Published: June 2014

Extraskeletal osteosarcoma (ESOS) is a rare malignancy, which commonly presents with metastatic disease. Like their osteogenic counterparts, these tumors commonly metastasize to lungs and bones. We report the fluoro-deoxyglucose positron emission tomography findings in a case of ESOS presenting with a combination of rare metastatic sites such as brain, kidney and the bone marrow.
Systemic Lupus Erythematosus (SLE) Complicated by Neuromyelitis Optica (NMO – Devic's Disease): Clinic-Pathological Report and Review of the Literature
Authors: Adawi Mohammad , Bisharat Bishara , Bowirrat Abdalla
Published: June 2014

Neuromyelitis optica (NMO) is usually a relapsing demyelinating disease of the central nervous system associated with optic neuritis, transverse myelitis involving three or more contiguous spinal cord segments, and seropositivity for NMO-IgG antibody. NMO is often mistaken for multiple sclerosis and there are relatively sporadic publications about NMO and overlapping systemic or organ-specific autoimmune diseases, such as systemic lupus erythematosus (SLE). We described a unique case of a 25-year-old Arab young woman who was diagnosed with SLE, depending on clinical, laboratory investigations and after she had fulfilled the diagnostic criteria for SLE and had presented the following findings: constitutional findings (fatigue, fever, and arthralgia); dermatologic finding (photosensitivity and butterfly rash); chronic renal failure (proteinuria up to 400 mg in 24 hours); hematologic and antinuclear antibodies (positivity for antinuclear factor (ANF), anti-double-stranded DNA antibodies, direct Coombs, ANA and anti-DNA, low C4 and C3, aCL by IgG and IgM). Recently, she presented with several episodes of transverse myelitis and optic neuritis. Clinical, radiological, and laboratory findings especially seropositivity for NMO-IgG were compatible with NMO. Accurate diagnosis is critical to facilitate initiation of immunosuppressive therapy for attack prevention. This case illustrates that NMO may be associated with SLE.

Avaliação dos cursos do Programa Nacional de Formação de Administração Pública (PNAP): a visão dos discentes de uma instituição federal de ensino superior
Authors: Grohmann Márcia Zampieri , Riss Luciana Aita , Battistella Luciana Flores
Published: June 2014

O presente estudo tem por objetivos: conhecer os níveis de aceitação (mensurados pelas dimensões utilidade, facilidade, prazer, concentração, norma subjetiva e controle) e satisfação (mensuradas pelas dimensões confirmação das expectativas, atitude e satisfação) em relação aos cursos do Programa Nacional de Formação de Administração Pública (PNAP); conhecer o perfil dos alunos do PNAP em uma Instituição Federal de Ensino Superior (IFES) e verificar se o perfil dos respondentes interfere na aceitação do ensino a distância e com a satisfação e atitude frente aos cursos do PNAP. Para tanto, foi realizada uma pesquisa descritiva e quantitativa, pautada no modelo de Lee (2010), 236 alunos que posicionavam-se numa escala de 1 (discordo totalmente) a 7 (concordo totalmente). Os resultados apontaram boa avaliação em todas as dimensões, sendo que a menor média foi para a norma subjetiva (4,88) e a dimensão melhor avaliada foi atitude (6,14). Constatou-se, também, que houve influência do perfil em 16,96% das variáveis, fato que leva a concluir que o perfil do respondente interfere muito pouco nas percepções dos alunos sobre os cursos PNAP. Conclui-se que este é um estudo exploratório, porém contribui para a compreensão do ensino a distância por incluir novas dimensões aos estudos de utilização e aceitação de tecnologias no ensino, como confirmação de expectativas e satisfação.
O processo decisório e suas implicações na cooperação universidade, empresa e governo: um estudo de caso
Authors: Eberhart Mara Elizete , Pascuci Lucilaine
Published: June 2014

As universidades públicas assumem, ao lado de suas funções institucionais de ensino e pesquisa, também o papel de agentes propulsores do desenvolvimento sócio-econômico ao estabelecerem uma ponte entre governo e empresas. Todavia, a característica complexa e pluralista destas organizações influencia o processo decisório e, conseqüentemente, o adequado cumprimento deste papel integrador. O objetivo deste estudo foi identificar as implicações do processo decisório de uma universidade no cumprimento de seu papel no modelo da Hélice Tríplice, com base nos mecanismos de transferência de tecnologia adotados. Trata-se de um estudo de caso qualitativo, descritivo e ex-post-facto. Dados foram coletados através de entrevistas, documentos e observação não participante, e analisados por meio de técnicas de análise documental e de conteúdo. Resultados evidenciaram preponderância de características da Burocracia Profissional e de uma Anarquia Organizada no processo decisório, com impacto no movimento da hélice ao retardar ou acelerar seu movimento bilateral. Como implicações, destacaram-se a ambigüidade de objetivos entre os envolvidos, o forte aspecto político e a burocracia interna que ocasionam morosidade ou dinamicidade ao processo. Constatou-se que a Universidade tem cumprido seu papel de agente propulsor do desenvolvimento socioeconômico, bem como foi identificado o esforço institucional para criação de entidades híbridas que garantam maior autonomia e dinamicidade aos mecanismos de cooperação, a exemplo do Hotel Tecnológico, da Incubadora e do Escritório Verde.

O objetivo deste artigo é analisar o desempenho das escolas que oferecem o curso de Administração e participaram do Enade em 2009, utilizando o IDD para medir qual a diferença entre o desempenho observado e esperado que cada tipo de IES apresentou. A pesquisa foi descritiva e explicativa, com pesquisa bibliográfica e de campo para levantamento dos microdados disponibilizados pelo Inep. Conclui-se que o IDD traz equidade ao processo e questiona sensos comuns, como a superioridade dos estudantes das IFES e o sentimento de que as particulares agregariam mais valor aos estudantes.

O artigo aborda o processo de orçamento de despesas de marketing no setor de ensino superior, um instrumento relevante na gestão de recursos financeiros e gastos de marketing da organização. O estudo buscou analisar as características do processo de orçamento de despesas de marketing de uma instituição de ensino superior da região oeste do Estado de Santa Catarina a partir do modelo teórico proposto por Sarquis e Ikeda (2003). Trata-se de estudo empírico, exploratório, qualitativo, na forma de estudo de caso e cuja pesquisa de campo envolveu entrevistas em profundidade. Os resultados revelaram os procedimentos empregados pela instituição na elaboração do orçamento de despesas, na operacionalização das despesas de marketing, na contabilização das despesas e no controle orçamentário das despesas de marketing, assim como a existência de processo orçamentário estruturado semelhante ao modelo teórico de Sarquis e Ikeda (2003).

Este estudo empreendeu descrever e refletir sobre algumas das abordagens adotadas por um campus universitário, criado com vistas à identificação de vulnerabilidades e minimização de problemas de seu entorno, contribuindo com o Desenvolvimento Regional. Com a recente política nacional de expansão do Ensino Superior Federal, foi viabilizada a criação do campus Litoral da Universidade Federal do Paraná (UFPR Litoral), em Matinhos, litoral do Paraná. Para este estudo, foi conduzida pesquisa teórica e social de cunho qualitativo, por meio de análise documental e realização de entrevistas semi-estruturadas com atores sociais (gestores, docentes e coordenadores pedagógicos), que estão vivenciando historicamente o processo de implantação do campus. A pesquisa identificou: patrimônios e vulnerabilidades da região, que justificaram a viabilização do campus neste local; concepções de Desenvolvimento Regional em nível de sustentabilidade e ecodesenvolvimento adotadas institucionalmente; a formação de sujeitos por meio de uma abordagem metodológica diferenciada, que visa instrumentalizá-los a intervirem na realidade regional, por meio de abordagens específicas. A consolidação deste estudo permitiu compreender um pouco dos processos da UFPR Litoral, levantar algumas indagações sobre os modos com que esta se propõe a contribuir no desenvolvimento e algumas particularidades de uma proposta em ininterrupta constru-lapidação, que requer a continuidade de estudos e pesquisas.

Abstract. In situ measurements of ozone (O3), carbon monoxide (CO) and meteorological parameters were made from December 2007 to November 2009 at the Xianggelila Regional Atmosphere Background Station (28.006° N, 99.726° E; 3580 m a.s.l.), southwest China. It was found that both O3 and CO peaked in spring while the minima of O3 and CO occurred in summer and winter, respectively. A normalized indicator (marked as "Y") on the basis of the monthly normalized O3, CO and water vapor, is proposed to evaluate the occurrence of O3 downward transport from the upper, O3-rich atmosphere. This composite indicator has the advantage of being less influenced by the seasonal or occasional variations of individual factors. It is shown that the most frequent and effective transport occurred in winter (accounting for 39% of the cases on the basis of a threshold of the Y value larger than 4) and they can make a significant contribution to surface O3 at Xianggelila. A 9.6 ppb increase (21.0%) of surface ozone is estimated based on the impact of deep downward transport events in winter. A case of strong O3 downward transport event under the synoptic condition of a deep westerly trough is studied by the combination of the Y indicator, potential vorticity, total column ozone and trajectory analysis. Asian monsoon plays an important role in suppressing O3 accumulation in summer and fall. The seasonal variation of O3 downward transport, as suggested by the Y indicator at Xianggelila, is consistent with the seasonality of stratosphere-to-troposphere transport and the subtropical jet stream over the Tibetan Plateau.

Abstract. The Regional Carbon Balance in Amazonia (BARCA) campaign provided the first Amazon Basin-wide aircraft measurements of O3 during both the dry-to-wet (November and December 2008) and wet-to-dry (May 2009) transition seasons. Extremely low background values (<20 ppb) were observed to the west and north of Manaus in both seasons and in all regions during the wet-to-dry transition. On the other hand, elevated O3 levels (40–60 ppb) were seen during the dry-to-wet transition to the east and south of Manaus, where biomass burning emissions of O3 precursors were present. Chemistry simulations with the CCATT-BRAMS and WRF-Chem models are within the error bars of the observed O3 profiles in the boundary layer (0–3 km a.s.l.) in polluted conditions. However, the models overestimate O3 in the boundary layer in clean conditions, despite lacking the predominant NO source from soil. In addition, O3 simulated by the models was either within the error bars or lower than BARCA observations in mid-levels (3–5 km a.s.l.), indicating that the models do not represent the free troposphere – boundary layer gradient in O3. Total tropospheric O3 retrieved from OMI/MLS was higher than that simulated by the models, suggesting that the satellite observations are dominated by the middle troposphere and long-range processes and are not a~good indication of O3 conditions in the PBL. Additional simulations with WRF-Chem showed that the model O3 production is very sensitive to both the O3 deposition velocities, which were about one half of observed values, and the NOx emissions. These results have implications for the monitoring and prediction of increases in O3 production in the Amazon Basin as the regional population grows.
