La investigación sobre cultura organizacional en Colombia: una mirada desde la difusión en revistas científicas
Authors: Ruiz Yaz Belida , Naranjo Julia Clemencia
Published: July 2015

Cada vez existe más evidencia sobre el papel determinante de la cultura organizacional para lograr mejores niveles de desempeño y competitividad de las empresas. Esto ha hecho que crezca el interés por su estudio, sin embargo, en el caso de Colombia no se ha indagado sobre la investigación realizada en el tema. Este trabajo se encarga de hacerlo a partir de la revisión de los estudios publicados en revistas indexadas. Los resultados muestran que la investigación en el tema es bastante incipiente, si bien ofrece evidencia de la importancia de la cultura para la empresa colombiana, en general los trabajos se ocupan de caracterizar la cultura pero en pocos casos profundizan en la incidencia que ella tiene sobre los resultados del negocio. Se observa una tendencia a culturas orientadas a lo interno y poco flexibles. También se encuentra en los estudios en que prevalece el nivel descriptivo, descuidando el nivel explicativo que es el que realmente podría orientar el quehacer de los empresarios.

Palabras clave: Cultura organizacional, investigación, difusión científica.
Parejas viables que perduran en el tiempo
Authors: Cuervo Rodriguez Juan José
Published: July 2015

El presente artículo científico presenta resultados del proceso llevado a cabo en el proyecto de investigación docente "Mecanismos de autorregulación en parejas viables que perduran en el tiempo". Se soporta en una mirada compleja de la psicología basada en una epistemología de la construcción. En el ámbito metodológico, se inscribe en los estudios de terapia familiar desde una perspectiva de la comunicación humana como un todo integrado. Participaron nueve parejas. Los criterios de inclusión fueron: cinco o más años de convivencia, participación voluntaria, no presentar (ni haber presentado) problemáticas especiales que ameriten intervención psicoterapéutica y la obtención de un porcentaje significativo en el uso de estrategias de comunicación asertiva en la resolución de conflictos. El método general utilizado fue el análisis de la comunicación en tarea de conversación. Los principales hallazgos señalan una estrecha relación entre el contexto de desarrollo de las parejas, la emergencia de códigos comunicacionales propios y la posibilidad de perdurar en el tiempo; también, se resalta el tipo de comunicación asertiva o constructiva, la construcción de valores como el respeto y la aceptación de las diferencias, y el deseo por vivir y construir bienestar común, como elementos constitutivos de su identidad como pareja.
Creatividad y subjetividad: su expresión en el contexto escolar
Authors: Díaz Gómez Álvaro , Mitjáns Martínez Albertina
Published: July 2015

En este artículo se desarrolla una conversación entre la psicóloga cubano-brasileña Albertina Mitjáns Martínez y el psicólogo colombiano Álvaro Díaz Gómez sobre la perspectiva histórico-cultural de la subjetividad en la teorización de la creatividad. La idea central que se argumenta es que la creatividad es una expresión de la subjetividad en su doble y simultánea condición de subjetividad individual y subjetividad social, por lo que se despliega en diferentes ámbitos, entre ellos el contexto escolar.
La interpretación de enunciados condicionales como bicondicionales y su problemática en la tarea de selección
Authors: López Astorga Miguel
Published: July 2015

En diversas ocasiones, los enunciados condicionales son perfeccionados, esto es, entendidos como bicondicionales. Este hecho provoca problemas para la interpretación de textos en general y para la comprensión correcta de las instrucciones de la tarea de selección en particular. Habitualmente, los resultados de esta tarea son extraños y, por ello, han surgido teorías que tratan de explicarlos a partir de hipótesis relativas a determinados mecanismos mentales o tipos de razonamiento especiales en los seres humanos. En este trabajo, tratamos de demostrar, revisando críticamente un experimento concreto presente en la literatura, que no es necesario aceptar tales hipótesis y que se puede explicar lo que sucede en dicho experimento asumiendo, simplemente, que los participantes perfeccionan algunas reglas condicionales que se proponen en él.

Published: July 2015

El propósito del estudio fue describir la formación en psicometría en los programas de pregrado de psicología. Para ello se revisaron los planes de estudio y los programas de psicometría de 23 programas académicos de psicología de Bogotá y Chía, y se realizaron entrevistas a 7 profesores del área. A partir del análisis descriptivo de los datos se encontró que en promedio se imparte un curso de psicometría, la estrategia pedagógica de mayor uso es la clase magistral, siendo los temas más abordados validez y confiabilidad; el autor de mayor referencia fue José Muñiz y el software de mayor uso el Statistical Package for the Social Sciences (SPSS). Se concluye que el curso de psicometría representa el 1 % de la formación curricular en psicología, y se desarrolla acorde con los principios definidos en los estándares de calidad de la APA (2011) referidos a la formación en psicología. Finalmente se presentan sugerencias para fortalecer la formación en el área a nivel de pregrado.
Cambios en las relaciones de trabajo: paradojas y consecuencias en el actual mundo del trabajo
Authors: Andrade Jaramillo Verónica
Published: July 2015

El objetivo del presente artículo es realizar una reflexión conceptual orientada a comprender los cambios acontecidos en el mundo del trabajo en las últimas décadas, por ser estos trascendentales para analizar la relación persona-trabajo. Dichos cambios se guían al menos a través de tres tendencias: la competición, la tecnologización y la globalización. Se mencionan las paradojas del actual mercado(s) de trabajo, y se explicitan seis cambios concretos producto de las tendencias y las paradojas; entre estos se mencionan la precarización del trabajo y el cambio en el funcionamiento de las organizaciones; los cambios en las formas y manifestaciones del trabajo; el cambio en la forma de representarse el ser humano al respecto del trabajo; los cambios en los criterios para la inclusión (y exclusión) y mantenimiento en el mercado de trabajo y la responsabilización del sujeto al respecto de su empleabilidad; los cambios en la configuración de la subjetividad y el lugar que el trabajo ocupa en ella incluyendo el establecimiento del contrato psicológico, la construcción de la carrera, la identidad, y la forma de representarse la agencia; y por último los cambios en la forma de gestionar el recurso humano al interior de las organizaciones. Se concluye que el estudio e intervención sobre el actual mundo del trabajo, requiere salir de visiones lineales y de causa-efecto, para contar con análisis reflexivos e intervenciones más pertinentes y atinadas, dada la complejidad que reviste hoy en día el mundo del trabajo.
Comparative Evolution of DuplicatedDdx3Genes in Teleosts: Insights from Japanese Flounder,Paralichthys olivaceus
Authors: Wang Zhongkai , Liu Wei , Song Huayu , Wang Huizhen , Liu Jinxiang , Zhao Haitao , Du Xinxin , Zhang Quanqi
Published: July 2015

Following the two rounds of whole-genome duplication that occurred during deuterostome evolution, a third genome duplication event occurred in the stem lineage of ray-finned fishes. This teleost-specific genome duplication is thought to be responsible for the biological diversification of ray-finned fishes. DEAD-box polypeptide 3 (DDX3) belongs to the DEAD-box RNA helicase family. Although their functions in humans have been well studied, limited information is available regarding their function in teleosts. In this study, two teleost Ddx3 genes were first identified in the transcriptome of Japanese flounder (Paralichthys olivaceus). We confirmed that the two genes originated from teleost-specific genome duplication through synteny and phylogenetic analysis. Additionally, comparative analysis of genome structure, molecular evolution rate, and expression pattern of the two genes in Japanese flounder revealed evidence of subfunctionalization of the duplicated Ddx3 genes in teleosts. Thus, the results of this study reveal novel insights into the evolution of the teleost Ddx3 genes and constitute important groundwork for further research on this gene family.
The Hairless Stem Phenotype of Cotton (Gossypium barbadense) Is Linked to aCopia-Like Retrotransposon Insertion in aHomeodomain-Leucine ZipperGene (HD1)

Published: July 2015

Cotton (Gossypium) stem trichomes are mostly single cells that arise from stem epidermal cells. In this study, a homeodomain-leucine zipper gene (HD1) was found to cosegregate with the dominant trichome locus previously designated as T1 and mapped to chromosome 6. Characterization of HD1 orthologs revealed that the absence of stem trichomes in modern Gossypium barbadense varieties is linked to a large retrotransposon insertion in the ninth exon, 2565 bp downstream from the initial codon in the At subgenome HD1 gene (At-GbHD1). In both the At and Dt subgenomes, reduced transcription of GbHD1 genes is caused by this insertion. The disruption of At-HD1 further affects the expression of downstream GbMYB25 and GbHOX3 genes. Analyses of primitive cultivated accessions identified another retrotransposon insertion event in the sixth exon of At-GbHD1 that might predate the previously identified retrotransposon in modern varieties. Although both retrotransposon insertions results in similar phenotypic changes, the timing of these two retrotransposon insertion events fits well with our current understanding of the history of cotton speciation and dispersal. Taken together, the results of genetics mapping, gene expression and association analyses suggest that GbHD1 is an important component that controls stem trichome development and is a promising candidate gene for the T1 locus. The interspecific phenotypic difference in stem trichome traits also may be attributable to HD1 inactivation associated with retrotransposon insertion.

Ethics and the Law: Practical Applications in the Neonatal Intensive Care Unit
Authors: DeTora Adam W. , Cummings Christy L.
Published: July 2015

Neonatologists may be unfamiliar with the many legal precedents and federal, state, and local laws that may affect medical practice in the United States. Knowledge of specific laws and court cases pertinent to neonatology is essential for medical practice, particularly in today’s increasingly litigious environment. This article reviews several federal and state laws applicable to neonatology and relevant legal cases that involve neonates that have led to the creation of case law in certain states. Two ethically challenging cases are presented and discussed as theoretical examples of how relevant law and court cases may be applied to neonatal practice. Topics include the attempted resuscitation of an infant or withdrawal of life-sustaining interventions despite parental objection, the right of infants to receive appropriate medical therapy in the emergency department and elsewhere in the hospital (regardless of congenital anomalies or prematurity), and difficulties providing end-of-life care to infants.

Seismotectonic-Geologic Hazards Zoning of Iran
Authors: Arian Mehran
Published: July 2015

Seismotectonic-geologic hazards zoning map of Iran is drawn based on deterministic seismic hazards evaluation using the seismicity records, structural trends, tectonic settings, fault ruptures and neotectonics activities in Iran. This map has been prepared to indicate the seismotectonic-geologic hazards of Iran. It contains the earthquake hazards parameters such as b value and Mmax for the nineteen seismotectonic provinces. Furthermore, Moho discontinuity depth, seismogenic layer depths and seismic rates for all provinces are investigated. The majority of deformation in Iran has been concentrated in the continental crust of the country. Zagros and Alborz experience deep earthquakes that are an indication of existence of the thick-skinned tectonics. Finally, some provinces such as Piranshahr- Borojen, East Iran, Naien- Rafsanjan and East Alborz, which include main suture zones of Iran, have faced high seismic hazards.

Resumen

Este estudio se realizó con el fin de preparar un mapa zonal de amenazas seismotectónicas y geológicas de Irán con base en la evaluación de amenazas sismícas deterministas a través de los registros sísmicos, las tendencias estructurales, las configuraciones tectónicas, las rupturas de fallas y la actividad neotectónica en Irán. Este mapa contiene los parámetros de amenaza sismológica como los valores b y Mmax para las 19 provincias sismotectónicas del país. Además, se investigó la profundidad de la Discontinuidad de Mohorovičić, las capas sismogénicas profundas y las clasificaciomes sísmicas para todas las provincias. La mayoría de la deformación de Irán está concentrada en la corteza continental del país. Las provincias de Zagros y Alborz experimentan terremotos profundos que indican la existencia de una configuración tectónica de capa gruesa. Finalmente, algunas provincias como Piranshahr-Borojen, Este de Irán, Naien-Rafsanjan y Este de Alborz, que incluyen las principales zonas de sutura de Irán, han enfrentado grandes riesgos sísmicos.

Mitigation of Surface Aggregation in Modified Phthalocyanines as Potential Photo Sensitizers
Authors: Vander Valk Rory J. , Dwyer Patrick J. , Kelty Stephen P.
Published: July 2015

Important to the development of dye-sensitized solar cells is the longevity and photo-conversion efficiency of the dye. To improve cost effectiveness, dyes of superior thermal and chemical stability are desirable to extend device performance. In this study, we examine a series of peripherally fluorinated Zinc-Phthalocyanines (FxZnPc). Introduction of chemically inert fluorine and isopropyl fluoroalkyl groups on the periphery of the Pc improve the dye stability and allow for tunable photo-physical properties. Additionally, introduction of the bulky isopropyl fluoroalkyl groups help mitigate molecular aggregation in thin films which is known to be detrimental to maintaining the desired photo-physical properties of the surface coating. Using molecular dynamics and first principles modeling, various substituent effects on surface adhesion and aggregation over TiO2 surfaces are characterized for both symmetric and asymmetric substitution.
The Invocation at Tilburg
Authors: Coggins Owen
Published: July 2015

This paper investigates implicitly religious practices and explicitly (though ambiguously) religious descriptions of the extreme heavy metal music subgenre of drone metal, in a case study focussing on a concert tour of the band Gravetemple. Responding to a conception of “experience” found in scholarship on mysticism and in Bailey’s theoretical framework of Implicit Religion, I suggest a contribution via the work of Michel de Certeau. In The Possession at Loudon (1966), Certeau investigates a seventeenth century incident of demonic possession by presenting a “history of the history” of the event in a compilation of documents with commentary. Adapting this methodology to include ethnographic participant observation fieldwork at Gravetemple concerts and interviews with audience members, I also examine and present here fragments of previews, promotion material, artwork, reviews and comments by attendees, in order to assess the relation between such texts, understandings of implicit religion, and listeners’ experience of drone metal.
Relação entre resistência de linhagens tropicais de milho à podridão de espiga e ao acúmulo de fumonisinas provocados por Fusarium verticillioides

Published: July 2015

A infecção de grãos de milho por Fusarium verticillioides, agente causal da podridão da espiga, pode resultar na produção de micotoxinas do grupo das fumonisinas. A resistência genética é a forma de controle mais eficiente dessa enfermidade. Assim, o objetivo do trabalho foi buscar fontes de resistência em linhagens de milho tropical à F. verticillioides e à produção de fumonisinas. Seis linhagens tropicais de milho, três, pré-classificadas como resistentes e três, pré-classificadas como suscetíveis à F. verticillioides, foram submetidas à inoculação do patógeno e posteriormente, avaliadas quanto à severidade da podridão de espiga, incidência de grãos sintomáticos e concentração de fumonisinas. Os resultados mostraram que as linhagens R1 e R3 apresentaram alta resistência à infecção do patógeno. No entanto, apenas a R3 foi resistente ao acúmulo de fumonisinas. Dessa forma, sugere-se que a ausência de relação entre intensidade da doença e níveis de fumonisinas seja fator inerente desse patossistema. Assim, não é possível assegurar que grãos assintomáticos quanto à infecção por F. verticillioides, estejam livres de contaminação por fumonisinas.

Published: July 2015

Alecrim da Chapada (Lippia gracilis Schauer) é considerada uma planta rica em óleo essencial e possui atividade antimicrobiana comprovada, devido aos monoterpenos fenólicos carvacrol e timol. O objetivo deste trabalho foi avaliar o efeito in vitro do óleo essencial e dos extratos etanólicos de raízes e folhas de L. gracilis no controle do fungo Monosporasccus cannonballus, causador do colapso do meloeiro. O extratos foram testados nas concentrações de 2500, 5000 e 7500 ppm e o óleo essencial de L. gracilis foi avaliado nas concentrações 255, 340 e 425 ppm tendo também um controle positivo com o fungicida comercial Captan(r) e um negativo apenas com meio BDA (batata, dextrose, ágar). Discos de micélio com 3 mm de diâmetro foram inoculados no centro de placas de Petri e as medições do crescimento micelial do fungo foram realizadas 48 horas após a montagem do experimento. Verificou-se que o óleo essencial de L. gracilis nas três concentrações testadas foi eficiente para o controle do fungo, com percentuais de inibição de 100%, em comparação ao tratamento com o controle negativo (0%) que não apresentou inibição. O extrato radicular, nas concentrações de 5000 e 7500 ppm e o extrato foliar na concentração de 7500 ppm também proporcionaram um percentual de inibição de 100%.

Published: July 2015

Ceratocystis sp. é um fungo que coloniza o xilema, agente causal de murcha e seca em diversas plantas lenhosas. O presente trabalho teve como objetivo acompanhar a colonização deste fungo na superfície de plantas de eucalipto (Eucalyptus sp.). Foram utilizados 5 isolados de Ceratocystis de diferentes hospedeiros (eucalipto, cacau, manga, teca e atemóia). Para isso, plantas de eucaliptos (clone 219) tiveram parte do seu sistema vascular exposto. Nesta região foi depositada uma suspensão contendo 106 esporos. Como testemunha, uma planta foi inoculada somente com água destilada autoclavada. Após a inoculação, estas plantas foram mantidas em câmara úmida a 25 oC no escuro. Parte da área inoculada foi coletada em intervalos de tempo pré-determinados (6, 12 e 24 horas), e fixadas em solução de "Karnovsky". As amostras foram preparadas e analisadas ao microscópio eletrônico de varredura. Todos os isolados foram capazes de germinar, penetrar e se desenvolver nos elementos de vasos de plantas de eucalipto no período de 6 horas. O isolado de cacau foi o que aparentemente teve o desenvolvimento mais lento dentro dos períodos estudados. Foi observada a germinação de ascósporos, clamidósporos e de conídios do tipo cilíndrico neste período. Doze horas após a inoculação ocorreu aumento da quantidade de micélio de todos os isolados testados. Nos casos dos isolados de manga e eucalipto foi possível observar a formação de novos clamidósporos. Vinte e quatro horas após a inoculação, com exceção do isolado de cacau, todos os outros isolados já apresentavam a formação de conidióforos cilíndricos. Este estudo comprova que isolados deste fungo, mesmo que provindos de outros hospedeiros, são capazes de se desenvolver no xilema do eucalipto.

SENSIBILIDADE DE ESPECTROS DE ONDAS OCEÂNICAS RECUPERADOS POR RADAR DE ABERTURA SINTÉTICA

Published: July 2015

SAR (Synthetic Aperture Radar ou Radar de Abertura Sintética) é o único sensor transportado por satélites capaz de medir o espectro direcional de ondas. Sua elevada cobertura espacial e temporal permite caracterizar o estado de mar, especialmente a região de baixa frequência do espectro de energia, que vem sendo assimilada em modelos numéricos de previsão de ondas em diversos centros operacionais espalhados pelo globo. Contudo, a extração do espectro de ondas de uma imagem SAR é um procedimento complexo. Alguns modos de operação não permitem o emprego de imagens sequenciais para resolver a ambiguidade direcional de propagação das ondas, o que requer informações adicionais, geralmente obtidas de um modelo de ondas. A dependência destas informações adicionais é investigada aplicando-se a inversão clássica de Hasselmann a alguns estados de mar teóricos. Esta abordagem é baseada na transformação analítica do espectro direcional de ondas sobre o espectro de imagem SAR correspondente. A solução deste problema inverso é determinada por um algoritmo numérico que minimiza um funcional não linear. Apesar de amplamente utilizado por diversos centros operacionais de previsão, este método não foi extensivamente testado em cenários experimentais bem definidos. Os resultados mostram que a dependência investigada é bastante significativa, sobretudo no que diz respeito à direção de propagação das ondas, levantando questionamentos sobre a acurácia da técnica.

Published: July 2015

A modelagem espectral é uma das ferramentas importantes para a determinação de estimativa de parâmetros biofísicos de um local. Correlacionar a concentração e o fluxo de dióxido de carbono, por meio de medições indiretas é um grande avanço na área das geociências. A metodologia desenvolvida para o sequestro florestal de carbono CO2flux, CO2fluxEVI e CO2fluxEVI2, a partir do sensor Hyperion envolveu ambientes naturais e antrópicos, tornando-o eficaz quando associada à variabilidade de ecótipos existentes na Amazônia Brasileira. Resultados desse estudo apontaram que os índices NDVI, EVI e EVI2 podem compor a estrutura do índice de sequestro florestal de carbono, CO2flux. Entretanto, fez-se necessário avaliar a potencialidade e comparação dos índices em relação à detecção do sequestro florestal de carbono, associado as medições diretas de CO2 nas torres micrometeorológicas. Após o processamento das imagens hiperespectrais e análises estatísticas dos índices sugeridos pôde-se inferir que o CO2flux com a utilização do NDVI tem melhor ajustamento, quando associado aos dados de concentração de CO2 (ppm) medidos no topo das torres, e com os dados de fluxo (mol.m-2.s-1), uma vez que as correlações possuem similaridades e são estatisticamente significativos com os dados do sensor Hyperion.

Published: July 2015

This study aimed to identify the parasitical etiologic agents of visceral cysts in pigs from the central/northern region of Rio Grande do Sul State, Brazil. Fifty-eight cysts were found in livers during veterinary inspection of swine slaughtered from January 2008 to 2012. Collected samples were submitted to macroscopic and molecular analyzes. Polymerase chain reaction (PCR), DNA sequencing and BLAST alignment of sequences was used to molecular characterization of the samples. By PCR 10.3% (6/58) of tested samples were positive for Echinococcus granulosus sensu lato and 56.9% (33/58) for Cysticercus tenuicollis. In this study, it was verified the occurrence of larval forms of E. granulosus sensu lato and Taenia hydatigena in pig herds from the central/northern region of Rio Grande do Sul State. The presence of both parasites is relevant due to the economic losses for the meat industry. Additionally, E. granulosus sensulato has zoonotic importance and may be infecting pig herds in southern Brazil.

Published: July 2015

This paper describes the morphology of Cucullanus pinnai pinnai parasitizing Pimelodus maculatus in the Guandu River, Brazil, based on differential interference contrast (DIC) microscopy and scanning electron microscopy (SEM), providing new morphological data about this species of parasite. Nematodes were collected between May and October 2012 from specimens of Pimelodus maculatus in the Guandu River (22°48’2”S, 43°37’35”W), in the state of Rio de Janeiro, Brazil. Some characteristics of specimens of Cucullanus in this study fall within the range of morphological variations of previously studied C. pinnai pinnai. Most of the specimens studied here had excretory pore and deirids located at the posterior end of the oesophagus, a feature not recorded in previous studies of this species. In addition, the size of the gubernaculum was larger than the other specimens previously studied. The SEM and DIC analyses of C. pinnai revealed several morphological details of the cephalic region and the tail papillae. With regard to the polymorphism of C. pinnai, morphological and genetic studies of this cucullanid nematode are needed, involving large numbers of host species and a wide geographical distribution.
Investigating the changing deformation mechanism beneath shallow foundations
Authors: Madabhushi S. S. C. , Haigh S. K.
Published: June 2015

The design of shallow foundations has traditionally used a mixture of plasticity-based solutions to find the ultimate limit state and either a factor of safety on the plasticity solution or a linear elastic solution to attempt to design for the serviceability limit state. The serviceability limit state is intrinsically linked to the deformation mechanism that occurs beneath the shallow foundation in service. A better understanding of these soil movements can pave the way for more rational design approaches. In this paper, small-scale experimental work is used to show that the deformation mechanism beneath strip and circular foundations continuously changes as the footing is displaced. The mechanisms observed at intermediate settlements, noted to be typical design points, are best described by a mixture of solutions. Linear mixes of idealised fields were analysed using an upper bound approach to determine the load–displacement behaviour of each mix. The envelope of lowest upper bounds indicated that the optimal mix of fields changes depending on the footing settlement. At typical design points for shallow foundations mixtures dominated by ellipsoidal cavity expansion mechanisms were found to be optimal for both axisymmetric and plane strain cases. Comparison of theoretical and experimentally measured predictions indicated that using linear mixes of fields gives a good approximation to the true behaviour and may be used for settlement-based design approaches in the future.

This paper presents an experimental investigation into the tensile behaviour of corroded steel bars under different strain rates. Accelerated corrosion tests were conducted on rebars embedded in concrete by the impressed current method. The influence of corrosion and strain rates on the mechanical properties was discussed. The results showed that almost all of the corroded steel bars failed at the minimum cross-section, and the strain rate and the corrosion degree had significant influences on the yield and ultimate strengths of the steel bars. As the strain rate increased both the yield and ultimate loads increased, but strain rate effects decreased with increased corrosion degree. With increases in the average corrosion degree, the nominal yield strength, ultimate strength and ultimate strain of the steel bars decreased significantly and the yield plateau shortened or even disappeared. However, the yield strength and the ultimate strength based on the minimum cross-sectional area did not decrease, which could be attributed to the uneven distribution of the cross-sectional area along the bar. Compared with the static tensile strengths of corroded rebars, the nominal yield strength and ultimate strength under high strain rate were more influenced by the corrosion degree.

Published: June 2015

Foamed concrete has proven to be an effective alternative to granular fills and is now widely used internationally. With increasing demand for lightweight materials for buildings in order to improve sustainability, foamed concrete has also developed as an ideal material for this purpose, and many countries utilise construction with precast foamed concrete blocks. However, at densities lower than current technology allows, typically <500 kg/m3, foamed concretes are more prone to instability of the fresh mix. Furthermore at very low densities, ≤300 kg/m3, instability is almost inevitable, greatly limiting the potential of foamed concrete for applications where mass is critical (e.g. weak soils, backfilling damaged structure etc.). This paper aims to illustrate the mechanisms of stability and instability in foamed concretes and demonstrates how ultra-low density mixes (down to plastic density of 150 kg/m3) can be successfully produced.

Authors: Sunardi Edy
Published: June 2015

DOI:10.17014/ijog.2.2.77-90The lithofacies association, mainly lithology and depositional sequences of the Brown Shale Unit of Pematang Group was studied based on recent fieldwork at Karbindo Coal Mine, in Kiliran Jao Subbasin,West Sumatra, Indonesia. The lower part of the Brown Shale Unit consists of coal and limestone facies which were deposited in a marginal lacustrine area. The limestone was generated by evaporatic processes characterized by the presence of primary calcite crystals. The upper part of the unit, from bottom to top, is composed of six facies associations, among all: amalgamated massive thick bedded shales, interlaminated shales and siltstones, interbedded grey and red shales, fossiliferous shales, massive thick bedded shales, and interlaminated shale and sandstone facies. Those facies were deposited in a shallow to deep water lacustrine environment, characterized by their lithology compositions, sedimentary structures, and fossil contents. The unit has such as high content of reworked organic matters-bearing shales and mudstones. Turbiditic sedimentary structures, gastropods, and bivalves are common.

Chagas disease (CD) is a zoonosis with the protozoan Trypanosoma cruzi as the causative agent. Dogs are considered the main domestic reservoir for T. cruzi in most Latin American countries and in some areas of the United States. In southern Brazil, despite being an endemic area of the disease, the prevalence in dogs is still unknown. This study aimed to evaluate the frequency of T. cruzi antibodies in dogs from urban and rural areas of Pelotas, RS, Brazil. A total of 227 canine sera were used for serological tests, of which 99 were from urban areas and 128 were from rural areas of Pelotas. Information regarding the environment and the possible risk factors (origin, rural contact, age, breed, confinement and gender) to which the dogs were exposed were recorded. Indirect immunofluorescence was used to assess the presence of specific immunoglobulins (IgG) anti-T. cruzi in the serum of dogs. Of the 227 sera analyzed, 81 (35.7%) exhibited anti-T. cruzi, which represented 34.3% of the dogs from the urban area and 36.7% of the dogs from the rural area. Among the variables analyzed, rural contact and male gender showed an association with seropositivity for T. cruzi. The detection of T. cruzi antibodies in the serum of these dogs emphasizes the need to study trypanosomiasis in this important domestic reservoir of Chagas disease.

In this context, we carried out a study based on service-learning parameters. The aim of the study was twofold: to determine the impact on inmates of the physical education programme that was undertaken with university students; and to assess what university students’ learnt in the prison-based socio-educational intervention programme. This paper describes the context of the research and the methodological basis of service learning. The qualitative tools to gather the information were: two focus group; a semi-structured interview with a representative of the unit’s guards; and the students’ field dairy. We present results that demonstrate the impact of the physical, sports activity on the socialisation of inmates, in terms of aspects such as communication and personal skills. The results also show the effect of the programme on the university students’ learning processes, particularly with regard to the contextualisation of learning.

While acknowledging these very positive developments, teaching LGBT curricula content is contingent upon having educators understand the complexity of LGBT lives. The study adopted a qualitative mixed method approach. The study investigated how and in what ways barriers and facilitators of providing LGBT medical, health and social care curricula content figure in the accreditation policies and within undergraduate and postgraduate medical and healthcare teaching. This paper illustrates opposing views about curricula inclusion. The evidence presented suggests that LGBT content teaching is often challenged at various points in its delivery. In this respect, we will focus on a number of resistances that sometimes prevents teachers from engaging with and providing the complexities of LGBT curricula content. These include the lack of collegiate, colleague and student cooperation. By investing some time on these often neglected areas of resistance, the difficulties and good practice met by educators will be explored. This focus will make visible how to support medical, health and social care students become aware and confident in tackling contemporaneous health issues for LGBT patients.

The implementation was carried out with teacher educators in the education faculty. 8 doctorate students (mentors) provided technology mentoring implementation for one academic term to 9 teacher educators (mentees) employed in the Education Faculty. The data were collected via the mentee and the mentor interview form, mentor reflections and organization meeting reflections. As a result, the problems based on the mentor, on the mentee and on the organization/institution were determined. In order to carry out TMP more effectively and successfully, a 6M-framework (Modifying, Meeting, Matching, Managing, Mentoring - Monitoring) was suggested within the scope of this study. It could be stated that fewer problems will be encountered and that the process will be carried out more effectively and successfully when the structure in this framework is taken into consideration.
