How To Design a Bottomhole-Assembly Rotary-Speed Sweet Spot
Authors: Wilson Adam
Published: November 2017

This article, written by Special Publications Editor Adam Wilson, contains highlights of paper IPTC 18836, “How To Design a BHA Rotary-Speed Sweet Spot,” by Jeffrey R. Bailey, SPE, and Andrius Minkevicius, SPE, ExxonMobil; Alexander Bolzan and Victoria R. Wilkins, Hibernia Management and Development; and Joshua S. Pokluda, Esso Exploration and Production Nigeria, prepared for the 2016 International Petroleum Technology Conference, Bangkok, Thailand, 14–16 November. The paper has not been peer reviewed.

Correct placement of the rotary-speed sweet spot of a bottomhole assembly (BHA) provides multiple benefits toward achieving the ultimate goal of drilling to section total depth in a single trip. The process of BHA redesign and tuning for the desired operating parameters provides greater control over the drilling process. Vibration minimization through proper design and operation of the BHA facilitates drilling objectives that include reaching section depth in fewer trips and providing acceptable borehole quality to run casing to depth.

Introduction

A musician understands the basic principle of a stringed instrument: The frequency of the note made by the instrument varies with the length of the string span. Other parameters play a role, including the string properties and tension. However, once the instrument is tuned and the concert has begun, the musical notes are played principally by changing the length of the vibrating string.

As the finger position is changed on the fingerboard, the pitch of the note changes. Although this is a basic concept to a musician, it is not common today in the oil and gas industry for engineers to apply this concept to BHA design selection.

A BHA is a beam that may be rep-resented by a fourth-order differential equation. Model calculations proceed by subdividing the BHA into elements comprising short sections of pipe in a lumped-parameter model. A 2D model uses a state vector at each mass node comprising the lateral displacement in a plane, tilt angle relative to the center-line, bending moment, and beam shear load. In the lateral bending flex mode, a dynamic side force is applied at the bit at integral multiples of the rotary speed. In the rotary twirl mode, offset mass elements are used to investigate the stability of the BHA to eccentric mass and centrifugal forces.

The dynamic response is considered to be a perturbation from the static solution. The bending strain energy is related to the square of the bending moment in the beam, and calculating the length-averaged BHA bending energy provides a BHA bending-strain-energy vibration index.

Lower values of vibration indices are sought because the dynamic response to a reference input is then minimized (i.e., lower vibrations are then predicted by the model). All such modeled designs are perturbed by identical inputs, and the model results may then be compared on an apples-to-apples basis.
Development of Work Flow To Manage Fatigue of Bottomhole Assemblies
Authors: Wilson Adam
Published: November 2017

This article, written by Special Publications Editor Adam Wilson, contains highlights of paper IPTC 18682, “Development and Utilization of BHA-Fatigue-Management Work Flow,” by Hendrik Suryadi, SPE, and Phan Van Chinh, SPE, Schlumberger, prepared for the 2016 International Petroleum Technology Conference, Bangkok, Thailand, 14–16 November. The paper has not been peer reviewed. Copyright 2016 International Petroleum Technology Conference. Reproduced by permission.

A new fatigue-management work flow provides drillers with a tool to simulate and predict the life expectancy of bottomhole assemblies (BHAs) before fatigue causes problems. This new feature allows engineers to calculate and monitor the fatigue life. It also helps engineers to take appropriate action before a failure occurs downhole or to provide information to the maintenance team for preventive maintenance. Overall, this new approach allows engineers to manage drilling risks related to fatigue before any negative consequences.

Introduction

The oil and gas industry continues to drill wells that are deeper, more complex, and have greater extended reach and dogleg severity. These wells expose drillstring elements to higher loads and several kinds of cyclic stresses. The success of drilling operations relies on maintaining the integrity of the BHA and the drillstring. One of the more common catastrophic events related with BHA integrity is twistoff, where the BHA component parts from the drillstring downhole. Twistoff can be caused by the load exceeding the collar strength or by high shock, vibration, or corrosion, but the primary cause of twistoff is fatigue failure. With fatigue failure, the drillstring fails downhole despite the stress being below the material-strength specification. This is caused by fatigue accumulated over time. According to some reports, fatigue failure contributes to more than 60% of total drillstring failures.

Fatigue failure can occur under a wide range of conditions and environments; however, a higher risk of fatigue failure always exists when rotating drill collars and tools through high-dogleg intervals during the drilling.

With high rig operating costs and increasing BHA and wellbore complexity, increased focus has been placed on avoiding twistoff-related expenses such as

Cost associated with time required to trip out of the hole

Cost of fishing operations and to repair or replace failed equipment

Cost to perform sidetracking Engineers attempt to prevent drillstring failures by optimizing the drill-string and trajectory designs.

Core Ideas

We used the AMMI Bayesian model for selection of cowpea genotypes.

We identified two genotypes with more expressive genotypic values.

It is not possible to carry out the general recommendation of cowpea genotypes for the Brazilian Midwest.

Cowpea is one of the world's most important tropical and subtropical food sources. In Brazil, it is grown principally in three regions: the Midwest, the Northeast, and the North. This makes the genotype × environment (G×E) interaction a challenge on the recommendation of the best genotypes for these regions. The aim of this study was to use the additive main effects and multiplicative interaction model under the Bayesian approach to recommend the best genotypes for the Brazilian Midwest. Six trials using cowpea genotypes were conducted in the municipalities of Aquidauana, Chapadão do Sul, Dourados, and Primavera. The experimental design included a randomized block design with 20 treatments (17 lines and three cowpea cultivars) and four replications. We identified only two genotypes (G15 and G2) with more expressive genotypic values and whose credibility regions do not include zero. From the credibility regions built for the genotypic and environmental scores, we verify that these genotypes contributed to the G×E interaction, presenting specific adaptability to the subgroup of environments (E5, E6). These results indicate that it is not possible to carry out the general recommendation of high‐yielding cowpea genotypes for the Brazilian Midwest region.
Producing High‐Residue, No‐Till Fallow in the Low‐Rainfall Zone of the Pacific Northwest

Use of a stripper header to leave tall stubble for high‐residue no‐till.

Winter triticale outperforms winter wheat in low rainfall dryland production.

Tall crop residue reduces wind speeds at the soil surface.

The low‐rainfall wheat production zone of eastern Washington is subject to wind erosion because of fine‐textured soils, low soil organic matter content, and tillage‐based winter wheat–summer fallow practices. Annual no‐till spring cropping systems to replace the low‐residue, erosive summer‐fallow period have not been economical. We conducted a 4‐year study at Ralston, WA to evaluate winter triticale (× Triticosecale) and non‐semi‐dwarf winter wheat (Triticum aestivum) biomass production, yield, nutrient use efficiency, and seed‐zone soil moisture during no‐till fallow and establishment of fall‐seeded canola. Treatments included winter triticale and winter wheat, both harvested with either a stripper header or conventional cutter‐bar header. Winter triticale produced more grain per pound of N fertilizer and per inch of soil water available than winter wheat, and overall yield was 30–80% greater than that of winter wheat. Full‐height cereals produced 20–90% more biomass than semi‐dwarf winter wheat. Stripper‐header triticale stubble maintained with no‐till chemical fallow (NTCF) reduced average wind speed at the soil surface to less than one‐half of the average wind speed recorded over reduced‐tillage winter wheat fallow. Soil moisture in the 0‐ to 3‐inch seed zone was greater and more uniform in stripper‐header no‐till fallow than in reduced‐tillage fallow. Maintenance of soil moisture by stripper‐header standing stubble was conducive to timely planting and establishment of fall‐seeded canola and led to greater crop establishment in no‐till fallow. Growing a high‐biomass cereal crop such as winter triticale or standard‐height winter wheat and harvesting with a stripper header produces a high‐residue, no‐till fallow that is a viable alternative to the traditional winter wheat–fallow cropping system.

Simple, Simultaneous Gravimetric Determination of Calcite and Dolomite in Calcareous Soils
Authors: Rodriguez Juan B.
Published: November 2017

Core Ideas

The carbonate meter (CM) method was modified to measure calcite and dolomite.

The modified carbonate meter (MCM) method efficiently separated calcite and dolomite.

The MCM method can be done in any soil testing lab.

The MCM technique not only measures calcite and dolomite but also total inorganic C

The MCM categorized calcareous soils as calcitic, dolomitic, and calcitic‐dolomitic.

Literature pertaining to the determination of calcite and dolomite is not modern and generally describes slow methods that require expensive specialized apparatus. The objective of this paper is to describe a new method that requires no specialized equipment. The separation of calcite and dolomite was done by placing 0.2000 ± 0.0200 g of calcareous soil, 6‐mL glass vial with 4.0 mL of fresh 4 mol L–1 HCl–3% FeCl2 4H2O in a 50‐mL Erlenmeyer flask. The Erlenmeyer flask was capped with the tubed rubber stopper and the carbonate meter's (CM) initial weight was recorded to the accuracy of four decimal places. A second weight was recorded after 30 s of reaction, a third weight was recorded after 30 min of reaction, and the last weight was taken after 22 to 24 h. The linear regressions and correlation coefficient results for calcite and dolomite in calcite–dolomite–soil mixtures with the modified carbonate meter (MCM) were excellent. The precision for calcite was <5% in 92.6% of samples and that for dolomite was <10% in 98.8% of samples. Recovery for calcite was 100 ± 10% in 86.4% of samples and recovery for dolomite was 100 ± 10% in 97.5% of samples. The MCM technique efficiently separated calcite and dolomite in calcareous soils. This procedure is recommended for routine analysis of calcite and dolomite concentrations up to 450 g kg–1. The MCM is easy to follow with good precision and recovery.

Published: November 2017

The deployment of a systemic economic crisis in Ukraine was conditioned by the aggravation of the socio-economic situation in certain regions and the build-up of structural deformations in the economy and the preservation of an inefficient model of production organization. This situation requires the search for a new model of economic growth, which is based on the use of competitive advantages of regions and a combination of industrial, scientific and managerial potential of the domestic economy. Clustering is a form of internal integration that can provide both sustainability and a synergistic effect of counteracting global competition for today. The research of the foundations of the formation of a modern cluster theory is a significant theoretical and practical interest for the further development of a successful model of cluster policy in Ukraine. In addition, the important place in this judgment is the fact that this theory is in the stage of active formation and development. The purpose of the article is to study, analyze and develop the methods of assessment of efficiency of creating regional innovative clusters for dynamic development of economics. The article considers the methods of quantitative evaluation of clusters performance based on the analysis of effects of reducing transaction expenses, capital value, marketing expenses, innovation diffusion and employment of infrastructure in common. It was established that the application of innovative cluster approach is one of the most efficient tools in the fulfillment of tasks of enterprise modernization and ensuring the development of innovative sectors of economy. Cluster effects for regional economies are relative and, in general, can be used for estimating total cluster effect. The suggested variants of assessment of potential cluster effects will provide opportunities of carrying out a more complete cluster estimation and selection of the most efficient projects for increasing the efficiency of regional innovation clusters and dynamic development of economics.
Constraints on foreign aid effectiveness in the water, sanitation, and hygiene (WaSH) sector
Authors: Wayland Joshua
Published: November 2017

Numerous studies have sought to empirically test the effectiveness of foreign aid as a tool for international development, with often inconsistent or contradictory results. New sources of disaggregated aid data now allow researchers to test the impact of individual sectors of aid on sector-specific outcomes. The paper investigates the effectiveness of foreign aid in the water, sanitation, and hygiene (WaSH) sector and seeks to identify constraints on WaSH aid effectiveness in recipient countries. Multilevel latent growth, dynamic panel, and instrumental variable regression models were estimated on a panel dataset comprising 125 recipient countries over 20 years. WaSH aid was consistently associated with improved health outcomes in middle-income countries; no effect on those outcomes was observed in low-income countries. Potential constraints on the effectiveness of WaSH aid – including political, economic, institutional, and technical constraints – were examined using subgroup analysis. The effectiveness of WaSH aid was found to have been constrained by government ineffectiveness and regulatory quality in recipient countries. Countries with large rural populations also appear to have benefitted less from WaSH aid than more urbanized recipient countries.

Authors: Zupin Luisa , Polesello Vania , Segat Ludovica , Kamada Anselmo Jiro , Kuhn Louise , Crovella Sergio
Published: November 2017

Background: Lactoferrin is a member of the innate immune system acting in the first line of defence against pathogens, and it is known for its antibacterial, antifungal and antiviral activity, including HIV-1. Two polymorphisms, T29A and R47K, in the exon 1 region of the LTF gene (encoding for the lactoferrin protein) were previously described as able to influence the lactoferrin antimicrobial function.

Objectives: LTF T29A and R47K genetic variants were analysed in a Zambian population to unravel if these polymorphisms could play a role in HIV-1 mother-to-child HIV-1 transmission.

Methods: LTF T29A and R47K polymorphisms were genotyped, using allelic specific fluorescent probes and real time PCR, in a population comprising 101 HIV-1 positive mothers and 333 children born to seropositive mothers.

Results: Maternal LTF T29A A/A and A/G genotypes were found to be associated with decreased risk of HIV-1 MTCT, being more frequent among non-transmitter mothers respect to transmitter mothers.

Conclusion: Our data suggested that maternal LTF genetic background contributes to the susceptibility to HIV-1 transmission from mother to new-borns.

Authors: AttaAllah Heba Radi , Omar Ismail Ahmed Nagib , Abdelhalim Ahmed Shawkat
Published: November 2017

Purpose:

Spectral Domain Optical Coherence Tomography (SD-OCT) was used to evaluate retinal and vitreo-retinal changes that occur in highly myopic patients.

Methods:

This prospective study included 472 eyes of 472 patients suffering from high myopia (> -6.00 D), between May 2012 and December 2015. All patients were examined, using Cirrus HD OCT (Zeiss Cirrus TM HD-OCT model 4000), to detect any retinal or vitreo-retinal interface abnormalities.

All obtained data was analyzed using Statistical Package for the Social Sciences software version 17 (SPSS Inc, Chicago, IL, USA) and the paired two-sided t-test. Bivariate correlations were performed between different parameters using the Spearman correlation coefficient (r).

Results:

Mean spherical equivalent (MSE) was -13.11± 4.35D. Mean axial length (AL) was 28.5±1.62 mm. Posterior vitreous detachment (PVD) was the most frequent OCT finding; representing 33.4% of the cases, 13.7% of them were associated with macular traction. A statistically significant positive correlation was found between AL and MTM, full thickness macular hole, PVD with traction, and dome shaped macula (r = 0.49 and P = 0.001, r = 0.422 and P = 0.0001, r = 0.25 and P = 0.03, r=0.475, P=0.001 respectively)

Conclusion:

OCT is a valuable tool in detecting retinal and vitreo-retinal interface abnormalities in highly myopic eyes, and it can be used for follow up of those patients to avoid advanced retinal damage.

Cinema e educação: repertório, temáticas e articulações
Authors: Junqueira Filho Gabriel De Andrade
Published: November 2017

O artigo tem como origem o curso Cinema e Educação: repertório, temáticas e articulações, oferecido dentro da programação do projeto  Vagalume, Laboratório de Estudos em Audiovisual e Educação, do Programa de Alfabetização Audiovisual, na cinemateca Capitólio, em Porto Alegre(RS), entre setembro e outubro de 2015.Parte da premissa de que o cinema pode educar e ser um grande aliado do professor e dos alunos para conhecerem mais sobre os conteúdos curriculares e os projetos que pretendem realizar ao longo do ano, com diferentes propósitos (Xavier; Bergala; Duarte e Alegria; Fresquet; Fantin; Mello; Migliorin; Junqueira Filho e Barbosa). Para isso, é preciso conhecer o que o cinema já produziu sobre diferentes temáticas, dentre elas, as que interessam a professores e alunos a cada momento do ano letivo. Como saber que filmes selecionar para discutir uma temática? Como acessar esses filmes? Como elaborar um roteiro de exploração para cada filme e para cada temática? Essas foram as perguntas que deram origem ao curso e que procuramos responder coletivamente ao longo dos quatro encontros. Outras perguntas surgiram durante o curso, indicando especificidades de demanda dos alunos: Como organizar situações prazerosas nas quais professores e alunos de dois a três anos possam assistir a filmes e conversar sobre eles? Como o cinema pode ajudar os professores a reencantarem alunos do ensino médio, que vivem cotidianamente em meio à violência, para os estudos e para a vida? Essas trocas entre alunos e professores produziram uma ampliação significativa das possibilidades de articulação entre cinema e escola e reforçaram a necessidade de planejamento e de elaboração de projetos de trabalho para o uso de filmes nos diferentes níveis de escolaridade.
(In) versões didáticas: possibilidades poéticas para processos de formação docente
Authors: Bredariolli Rita Luciana Berti
Published: November 2017

Conhecimentos sobre as imagens e pelas imagens resultam de um trabalho de relação, de um trabalho de montagem, pelo qual situamos, em ação relacional, indícios, textos, lacunas e outras imagens visíveis ou não. Trata-se de um trabalho de imaginação: “imiscuir-se” nas imagens, ativando-as em montagem a outras imagens ou textos, impulsionando um movimento relacional que “age sobre a nossa própria atividade de saber e de pensar”. “Para saber, é preciso imaginar-se”. Partindo dessas considerações, abordaremos nesse texto as imagens – visíveis e não-visíveis - e a imaginação como possibilidades de formação docente. Apresentaremos algumas das variações conceituais sobre imagem em sua relação com o saber, enfatizando a revisão epistemológica que revitaliza e reposiciona o valor e a função das imagens e da imaginação no processo cognitivo e, sobretudo, como possibilidades de um processo de formação docente voltado ao ensino das artes, delineado pela assunção da importância, necessidade e inseparabilidade do exercício da inteligibilidade e sensibilidade.

Com uma abordagem metodológica cartográfica, propõe quatro vias para a compreensão do denso território que se observa. Estas vias são: a via que prioriza a história da cultura e a história da arte como fundamento para o ensino da arte; a via que vincula o ensino da arte à escola e, portanto, o inclui nas pedagogias que envolvem todos os campos do saber; a via que explica o ensino da arte desde o campo do saber; a via da epistemologia dos saberes, do saber artístico e do ensino da arte.
Artes Visuais em um espaço não formal de educação: uma mostra e uma experiência de mediação como interface público/arte
Authors: Jardim Filho Airton Jordani
Published: November 2017

O presente artigo objetiva discutir a mostra [gaveta(s)], proposta, elaborada e produzida durante a disciplina de Ação Educativa em Espaços Culturais, do Programa de Pós-Graduação em Artes Visuais do Centro de Artes da Universidade do Estado de Santa Catarina (PPGAV/CEART/UDESC), que apresentava a gaveta como metáfora da memória. Compreendendo que a mediação não deve ser a única atribuição dos educadores atuantes nesses espaços e, tendo por base as referências teóricas discutidas em sala de aula, os alunos da disciplina, ao projetar e colocar em prática uma mostra de trabalhos artísticos, puderam participar de todas as etapas de uma exposição, desde a concepção inicial até sua divulgação. Nesse sentido, o texto apresenta os desdobramentos da experiência de mediação realizada durante a exposição. Além disso, a reflexão presente nesse artigo busca posicionar conceitualmente a mediação como interface interativa, a partir da proposição de Grossmann (2011).
Arte contemporânea e ensino da arte: contextos de produção de sentido
Authors: Ledur Rejane Reckziegel
Published: November 2017

O artigo discute os desafios da educação atual, a partir do olhar e da experiência estética com a arte contemporânea no contexto escolar. Tem como referência duas pesquisas acadêmicas (LEDUR, 2005, 2013) em relação à produção de sentidos na interação com a arte contemporânea de professores de arte e alunos do Ensino Fundamental de uma rede municipal de ensino. Autores como Cauquelin (2005), Bourriaud (2009), Bauman (1998, 2007), Sibilia (2012) e Acaso (2009) fundamentam as reflexões referentes às transformações da pós-modernidade; as análises da experiência estética partem dos estudos de Bakthin, Dewey e da semiótica greimasiana. Ao considerar a interação com a arte contemporânea como uma experiência sensível e inteligível, observou-se a recorrência de sentidos específicos apoiados em princípios fundamentais da experiência estética com a arte contemporânea. A compreensão construída em torno da percepção dos sentidos, produzidos pelos alunos na interação com a arte contemporânea, foi representada por meio do “quadrado semiótico”. Nesse esquema, salientam-se os regimes de contemplação, interrogação, significação e percepção, como resultantes da apreensão estética da arte contemporânea.
Por que aprender cinema no hospital? Experimentações com a sétima arte em contexto não formal de educação
Authors: Fresquet Adriana , Omelczuk Fernanda
Published: November 2017

O artigo tem como objetivo compartilhar algumas ressonâncias da aprendizagem de cinema no contexto hospitalar a partir do que identificamos como quatro potências: psicopedagógica, estética, ética e sociopolítica. Essas potências permitem-nos pensar tanto a experiência particular da qual partimos, como sinalizam a possibilidade de articulação entre os campos da Pedagogia Hospitalar, Classe Hospitalar e Ensino da Arte. Os conceitos de cinema, atividade criadora, aprendizagem da arte e educação no hospital que sustentam o trabalho estão em diálogo com Alain Bergala, Ana Mae Barbosa, Adriana Fresquet, Lev Vygotsky, Regina Fontes, dentre outros. Destacamos como reflexões futuras que, nesse contexto, os referenciais que trazemos mostram seus limites e nos impelem na invenção de outros enunciados para a Educação, para o fazer do professor, para o aprender e para as subjetividades.
Notas sobre uma Residência Pedagógica no Museu de Arte do Rio
Authors: Munhoz Angélica Vier , Costa Cristiano Bedin da , Guedes Betina Silva
Published: November 2017

O presente artigo parte de uma residência pedagógica realizada no Museu de Arte do Rio (MAR), para desenvolver uma análise das práticas produzidas pelos educadores que lá atuam. Essa análise coloca foco no espaço instaurado a partir das interlocuções realizadas entre público e obra, significando-o como um texto. Para tanto, estabelece com Roland Barthes o esteio teórico que subsidia o mapeamento de percepções e sensações realizado. Metodologicamente, cria formas de apontar ressonâncias entre as práticas de mediação desenvolvidas pelos educadores, um funcionamento curricular aberto à imprevisibilidade dos encontros, e a potência das múltiplas dimensões dos espaços engendrados nessa rede que tem por base a educação. Por fim, faz-se a defesa da mediação enquanto uma prática comprometida com a supressão do distanciamento existente entre os desejos do autor e a experiência do espectador, de maneira que a vivência artística seja, sobretudo, um convite à criação de novos sentidos: para a obra, para a arte, para a vida.

Published: November 2017

Este artigo busca compreender aspectos da natureza sígnica das imagens, mormente o que estas oferecem em termos de construção de sentidos para os sujeitos e para as culturas. A análise discute e trata as imagens não apenas pelo seu valor estético, mas, entende as imagens como potências que movimentam o cenário da contemporaneidade, em face do reconhecimento da multiplicidade de artefatos visuais que compõem o cenário atual compreende, que, constituem as imagens significativos lugares de aprender. A construção teórica é desenvolvida na perspectiva da Cultura Visual, por reconhecer este campo de conhecimento como sendo capaz de dar conta, ao menos em parte, dos estudos das imagens, das mídias, bem como do complexo campo visual.  Por fim, a discussão almeja colaborar para a qualificação da recepção da cultura da imagem como participe dos processos formativos que acontecem também fora das salas de aula. Sobretudo, o faz, por entender as imagens como componentes imprescindíveis dos saberes.
Mulheres Professoras do Peru: pesquisar em educação artística transitando em contextos formais e informais

Para 2017, está prevista a exposição Mulheres Professoras do Peru. Através desta pesquisa unimos o ambiente formal (escolas) aos espaços informais (museus) por meio de ações artísticas, patrimoniais e performativas.
Breves notas sobre o corpo: um diálogo com Gonçalo M. Tavares e Os Espacialistas
Authors: Moreira Maria Elisa Rodrigues
Published: November 2017

O corpo é o tema central que percorre o Atlas do Corpo e da Imaginação, obra lançada pelo português Gonçalo M. Tavares, em 2013. O texto, de caráter ensaístico-poético, dialoga com um conjunto de imagens produzidas pelo coletivo também português de artistas-arquitetos, “Os Espacialistas”. São algumas destas imagens que servem de mote para este artigo, no qual se apresentam algumas notas reflexivas introdutórias sobre o corpo, observando-se como imagem e texto se potencializam para a reflexão sobre esse objeto. Se o texto de Tavares aborda o corpo a partir de quatro grandes eixos (O corpo no método, O corpo no mundo, O corpo no corpo e O corpo na imaginação), as imagens do coletivo (e alguns de seus textos) desestabilizam esses eixos, cruzando-os transversalmente e provocando o leitor a pensar nas possibilidades e maneiras que os corpos têm de situar-se no mundo.
Corpo que paira, corpo que flui: corporeidades múltiplas na arte-vivência
Authors: Menezes Rosália , A-mi Jo
Published: November 2017

O objetivo deste artigo é apresentar reflexões críticas a propósito das relações entre o Corpo e os seus agenciamentos com o mundo (compreendido como corporeidade), mantendo com as experimentações artísticas um viés estratégico de territorialidade crítica enquanto “linha de fuga” – conforme Deleuze. Teoricamente, teceu-se um percurso que se iniciou com as perspectivas do corpo na clássica filosofia ocidental, entremeado por estudos de base sociológica (na discussão do processo civilizador e do corpo como coletividade) e de base histórica (do corpo contextualizado em sua relação com o mundo e com as artes). Assim, a arte-vivência com o corpo, aqui demonstrada, procurou constituir-se em corporeidades cuja travessia foi reconstruindo conceitos, percepções e ações sobre o corpo cena-em-si: objeto e ato de experiências artístico-pedagógicas.

Inquietações e mudanças na Educação Artística: mais de que nunca uma urgência
Authors: Paiva José Carlos de
Published: November 2017

O artigo escreve-se na primeira pessoa, como um exercício de reflexão, a partir da amplitude de responsabilidade política de um professor de educação artística, envolvido nas encruzilhadas de um tempo controverso onde se confronta a dignidade e imprescindibilidade da presença do artístico nas escolas com uma ofensiva ultra liberal que a pretende anular em favor de uma escola utilitarista que alimente as necessidade do sistema hegemónico e forneça sujeitos dóceis e adormecidos. As controvérsias que afrontam a dignidade humana no mundo contemporâneo exigem-nos entender  que, no terreno educativo, não se procura um modelo que se lhes contraponha mas se criem possibilidades de confrontação com o novo.

Zróżnicowanie dochodów gospodarstw rolniczych państw Unii Europejskiej – ujęcie czasowo-przestrzenne
Authors: Pietrzykowski Robert
Published: November 2017

Celem pracy było przedstawienie zmian w dochodach uzyskiwanych przez rolników w państwach należących do Unii Europejskiej z uwzględnieniem dodatkowych czynników jakimi są czas i lokalizacja w przestrzeni. W przeprowadzonych analizach zwrócono szczególną uwagę na państwa, które wstąpiły do Unii Europejskiej po roku 2004 (UE-11: Estonia, Czechy, Łotwa, Litwa, Polska, Słowacja, Słowenia, Węgry, Bułgaria, Rumunia i Chorwacja). Ze względu na makroekonomiczny charakter badań wykorzystano Rachunki Ekonomiczne dla Rolnictwa (RER). W pracy wykorzystano współczynnik autokorelacji Morana. W wyniku przeprowadzonych analiz stwierdzono występowanie dodatniej autokorelacji przestrzennej co potwierdziło występowanie klastrów dla państw wchodzących w skład Unii Europejskiej.
Świadomość młodzieży akademickiej na temat rolnictwa
Authors: Szafrańska Monika
Published: November 2017

Celem pracy jest ocena poziomu świadomości rolniczej młodzieży akademickiej z woj. małopolskiego oraz określenie wybranych czynników determinujących ten poziom. Ich znajomość może stanowić podstawę działań różnych podmiotów, które przyczynią się do wzrostu świadomości rolniczej młodego pokolenia. Zasadniczym źródłem danych wykorzystanych do analizy i wnioskowania były informacje pierwotne uzyskane z badań własnych, przeprowadzonych metodą PAPI na grupie 436 studentów. Do pomiaru i oceny świadomości młodzieży na temat rolnictwa wykorzystano indeks świadomości rolniczej. Jak wynika z przeprowadzonych badań, większość respondentów nie rozumie roli rolnictwa, którą odgrywa ono w gospodarce, społeczeństwie i środowisku. Determinantami poziomu świadomości rolniczej w grupie studentów były płeć oraz miejsce zamieszkania.
Wahania koniunkturalne na światowym i polskim rynku odtłuszczonego mleka w proszku w latach 2004-2016
Authors: Szajner Piotr
Published: November 2017

Działalność gospodarcza charakteryzuje się wahaniami koniunkturalnymi. Cykle koniunkturalne mogą dotyczyć całej gospodarki, jak i konkretnych sektorów. Mleczarstwo jest branżą, która ma duże znaczenie w polskim i światowym sektorze rolno-żywnościowym. Polskie mleczarstwo przeszło głębokie przemiany strukturalne i modernizacyjne. Po akcesji do UE nastąpiło silne powiązanie rynku krajowego, unijnego i światowego. Polska dysponuje nadwyżką mleka surowego (ok. 20%), która jest eksportowana, co skutkuje silnym uzależnieniem od sytuacji cenowej na międzynarodowym rynku. Analiza krajowego i światowego rynku chudego mleka w proszku potwierdziła, że wahania koniunkturalne są analogiczne, a ceny krajowe i światowe są silnie skorelowane. Wiedza na temat charakterystyki wahań koniunkturalnych ma utylitarny charakter, gdyż podmiotom branży umożliwia zarządzanie ryzykiem, a administracji przygotowanie efektywnych instrumentów polityki interwencyjnej.
Stan i perspektywy rozwoju rynku biogazu w UE i Polsce – ujęcie ekonomiczne
Authors: Gostomczyk Waldemar
Published: November 2017

Rynek biogazu rolniczego różni się w poszczególnych krajach europejskich. Zarówno w Europie jak i w Polsce podstawową formą jest wykorzystanie biogazu do wytwarzania energii elektrycznej i cieplnej. W dziewięciu krajach unijnych wytworzony biogaz wykorzystywany jest również w lokalnych sieciach gazowych oraz w transporcie, szczególnie komunalnym. W wytwarzaniu biogazu można opierać się na surowcach rolniczych (Niemcy) lub wykorzystaniu i przetworzeniu wszelkich odpadów rolniczych, przemysłowych i komunalnych (Dania, Szwecja). Celem artykułu jest przedstawienie dynamiki i struktury rozwoju rynku biogazu, wykorzystywanych surowców oraz opłacalności w różnych modelach prawno-finansowych. Przedstawione analizy pozwoliły wnioskować, że w przyszłości biogazownie mogą być ważnym elementem rynku energii, szczególnie na poziomie lokalnym oraz istotna częścią zrównoważonej gospodarki.

Celem opracowania było ukazanie współczesnego miejsca produktów regionalnych i tradycyjnych na współczesnym jednolitym rynku europejskim. Przybliżono zmiany zachodzące na tym rynku w ilości zarejestrowanych produktów regionalnych zarówno w Polsce jaki i innych krajach europejskich. Ponadto podkreślono projakościową i prozdrowotną rolę jaką przypisuje się tego typu żywności, na zróżnicowanym i zdominowanym przez masowe produkty rynku. Uwypuklono także marketingowy wymiar funkcjonowania tego rynku, zwracając uwagę na współczesne sposoby promowania tego typu produktów, jak również pokazano główne sposoby sprzedaży tej żywności. Ponadto zwrócono uwagę na główne czynniki brane pod uwagę w procesie zakupu jak również identyfikacji żywności tradycyjnej i regionalnej przez nabywców. Rozważania teoretyczne zostały poparte badaniami ankietowymi na grupie 360 przypadkowo dobranych osób za pośrednictwem internetu.
Polsko-niemiecka wymiana handlowa produktami rolno spożywczymi
Authors: Kowalska Anna
Published: November 2017

Celem opracowania jest przedstawienie zmian wielkości i struktury wymiany handlowej produktami rolno-spożywczymi Polski z Niemcami w latach 2003 – 2015. W analizie wykorzystano dane Ministerstwa Finansów publikowane przez IERiGŻ-PIB oraz dane z internetowych baz danych Eurostat oraz WITS – Comtrade. Wymiana handlowa produktami rolno-spożywczymi z Niemcami sukcesywnie się zwiększa, zarówno po stronie eksportu, jak i importu. Wraz z tendencją wzrostową w wymianie handlowej z Niemcami w latach 2003-2015 zmieniła się jej struktura asortymentowa. Wskaźnik TC pokazuje nadwyżkę eksportu nad importem większości grup produktów. Także analiza wskaźnika SI, potwierdziła specjalizację polskich produktów rolno-spożywczych na rynek niemiecki w przypadku 14 z 23 grup asortymentowych, a wysokie wartości wskaźnika GL w większości grup produktów rolno-spożywczych, potwierdzają umacniającą się pozycję producentów w tych grupach produktowych.
Polski handel zagraniczny warzywami i ich przetworami w latach 2001-2015
Authors: Jąder Karolina
Published: November 2017

Celem opracowania było przedstawienie i ocena zmian w handlu zagranicznym warzywami i ich przetworami w latach 2001-2015. Zbadano wielkość oraz wartość eksportu i importu warzyw świeżych i ich przetworów oraz obliczono saldo handlu zagranicznego tymi produktami. W celu zobrazowania zmian analizowany okres podzielono na cztery podokresy. Przy zastosowaniu wskaźników dynamiki określono zmiany jakie zaszły w ilości i wartości eksportu i importu w kolejnych podokresach w stosunku do lat ich poprzedzających. Wydzielenie czterech podokresów umożliwiło również zdefiniowanie zmian w strukturze towarowej i geograficznej handlu zagranicznego. Stwierdzono zwiększenie wielkości oraz wartości eksportu i importu, przy czym wyższy wzrost odnotowano w przypadku importu. W eksporcie szczególnie wzrosło znaczenie pomidorów oraz przetworów pomidorowych, natomiast w imporcie warzyw pozostałych. W strukturze geograficznej eksportu spadło znaczenie krajów Unii Europejskiej, natomiast wzrósł udział Wspólnoty Niepodległych Państw. W strukturze geograficznej importu odnotowano wzrost udziału krajów UE-15 oraz spadek krajów UE-12.
Podaż wiśni na rynku międzynarodowym a ceny skupu wiśni do przetwórstwa w Polsce
Authors: Kierczyńska Sylwia
Published: November 2017

Celem pracy było zbadanie związku czynników podażowych na rynku wiśni z cenami skupu wiśni do przetwórstwa w Polsce. Analizę związku pomiędzy cenami skupu wiśni a wielkością produkcji wiśni w poszczególnych krajach oraz poziomem eksportu wiśni przeprowadzono przy wykorzystaniu współczynników korelacji Pearsona oraz Spearmana. Wielkość produkcji wiśni w krajach, będących ich największymi producentami i eksporterami (Węgry, Serbia Polska) była ujemnie skorelowana z cenami skupu wiśni do przetwórstwa w Polsce. Wielkość produkcji wiśni w krajach będących ich importerami (Niemcy, USA) była również ujemnie skorelowana z cenami skupu wiśni w Polsce. Związek pomiędzy wielkością eksportu wiśni z Węgier, Serbii i Polski a cenami skupu wiśni w Polsce był słaby i nieistotny statystycznie. Korelacja pomiędzy wielkością eksportu wiśni z tych krajów a cenami skupu wiśni w Polsce była ujemna.
Występowanie efektu Kinga na wybranych rynkach rolnych w Polsce
Authors: Krawczak Marcin , Rembisz Włodzimierz
Published: November 2017

Efekt Kinga znany jest w literaturze naukowej już od początków XVIII wieku lecz do tej pory został on zbadany jedynie przez kilku ekonomistów. Ogólne omówienie zagadnienia w niniejszym artykule może być zalążkiem znacznie szerszych i bardziej szczegółowych badań zarówno ze strony teoretycznej jak i praktycznej. Wpierw przedstawiono przyjęte założenia oraz omówiono wcześniejsze prace dotyczące efektu Kinga by na koniec zweryfikować czy na sześciu rynkach w Polsce występuje efektu Kinga. Wykorzystane dane zostały pobrane z bazy danych GUS, które ewentualnie zostały uzupełnione danymi z Eurostatu.
Exclusión razonada del diseño de interiores en la currícula de la Facultad del Hábitat, UASLP / Reasoned Exclusion of Interior Design in the curricula of the Faculty of Habitat, UASLP
Authors: Ramírez Martínez Claudia
Published: November 2017

Introducción: El conocimiento del diseño de interiores se incluye en los contenidos de las diferentes universidades y escuelas de diseño en México. Su planteamiento implica ciertas críticas, pues a menudo es percibido como una subdisciplina del diseño o como un conocimiento de nivel técnico. Explicar las nuevas tendencias del diseño internacional, que incluyen en sus planes curriculares los asuntos de interiorismo, no puede quedar de lado en las instituciones mexicanas. Objetivo: La presente investigación tuvo como objetivo la reflexión de las inclusiones o exclusiones que se han propuesto en los diferentes planes curriculares de la Facultad del Hábitat de la Universidad Autónoma de San Luis Potosí, al ser una de las instituciones con un reconocimiento de 45 años de formación. Método: A través del estudio documental se abordan los enfoques que se han dado en los planes de estudio de las diferentes carreras propuestas en la Facultad del Hábitat; se analiza y detalla cronológicamente el abordaje y las razones por valores de exclusión o inclusión que el interiorismo ha tenido en cada una de las carreras, particularmente en las carreras de arquitectura, diseño urbano y del paisaje, así como diseño industrial. Resultados: A partir de la revisión se logró establecer las diferentes razones e implicaciones conceptuales dadas en figuras y mapas conceptuales en su uso de los diversos planteamientos. Se relacionaron las materias y cursos implementados en los años de existencia de la Facultad del Hábitat. Conclusiones: El desglosar y obtener las razones que permiten identificar las materias con contenidos de interiorismo deja ver que, si bien la Facultad del Hábitat actualmente no plantea directamente una licenciatura en diseño de interiores, su aprendizaje y transmisión a los estudiantes se ha dado a lo largo de su historia curricular. La inclusión de las tendencias del diseño de interiores se trata a través de las temáticas propuestas y de su adecuación en el campo profesional de cada una de las formaciones.
