Understanding Mobile Library Apps Continuance Usage in China: A Theoretical Framework and Empirical Study
Authors: Zhao Yang , Deng Shengli , Zhou Ruoxin
Published: September 2015

With the pervasiveness of mobile applications (apps), many Chinese libraries have begun to use apps to provide mobile services to users. Although many mobile library (m-library) apps have a high-downloaded rate in the App store, the rate of users continuing to use them remains extremely low, and the acceptance-discontinuance anomaly phenomenon (i.e., users discontinue using a m-library app after initially accepting it) is a common occurrence in China. This study develops an integrated model designed to explain and predict users’ continued usage of m-library apps based on the expectation confirmation model of information system continuance (ECM-ISC) and the theory of information system success, It incorporates habit, as a moderating variable of continuance intention and behaviour, into the model. Empirical data was collected from 396 users who had prior experience with m-library apps and was tested against the proposed research model using structural equation modelling. The results demonstrated that user perceived usefulness, expectation confirmation and satisfaction are important parts of the formation of m-library apps continuance usage. Furthermore, the three components of the information system success model, system quality, information quality and service quality, also have significant impacts on user confirmation and ultimately affect continuance usage. And the negative influence of habit on continuance intention and behaviour has been supported. The study will be useful for Chinese libraries to better understand users’ continuance usage behaviour and service demands, and in turn to optimize the function of apps and improve the quality of mobile services.
Optimisation of the emulsion liquid membrane
composition and demulsification for rhodium
extraction
Authors: Moyo Francis , Tandlich Roman
Published: September 2015

This study was aimed at designing an optimised
emulsion liquid membrane (ELM) for the extraction of
rhodium from precious metal refinery wastewaters. The
demulsification process and the structure of the optimised
ELM are reported on. Two optimised ELMs were prepared.
The first one contained a 30 % solution of toluene in
kerosene as diluent with the following concentrations of
the ELM components: 30.000 g/L (w/v) polyisobutylene,
10.870 g/L (m/v) of trioctyl amine and 51.001 g/L (m/v) of
SPAN 80. The second ELM contained the same diluent,
but the concentrations of the other ELM components in
it were as follows: 20.000 g/l of polyisobutylene, 10.268
g/l trioctyl amine and 50.024 g/l of SPAN 80. The stripping
phase was the same in both optimised ELMs, namely
a 2 M solution of HNO3. The stripping phase and the
diluent solution were mixed together in ratios of 1:1 and
2:1, respectively. Two methods were used to characterise
the microdroplet diameters, i.e. optical microscopy and
the Zeta-sizer. For the t-test, the p-value of 0.3018 at 5 %
level of significance showed that there was statistically no
significant difference in the mean micro-droplet size for 1:2
ELMs containing 20 g/l and 30 g/l of polyisobutylene after
40 minutes of emulsification. The best demulsification
results were obtained using the chemical demulsification
with polyethylene glycol with molecular weight of 400
g/mol (PEG 400) at 50 ± 1 °C for 24 hours. However,
significant carryover of toluene, trioctyl amine and
polyethylene glycol into the aqueous phase was observed.
Simulating from the Heston model: A gamma approximation scheme
Authors: Bégin Jean-François , Bédard Mylène , Gaillardetz Patrice
Published: September 2015

The Heston model is appealing as it possesses a stochastic volatility term as well as semi-closed formulas for pricing European options. Unfortunately, few simulation schemes for this model can handle the violation of the Feller Condition.
An algorithm based on the exact scheme of Broadie and Kaya to simulate price paths under the Heston model is introduced. In order to increase the speed of their exact method, we use a gamma approximation. According to Stewart, Strijbosch, Moors and Batenburg, it is possible to approximate a complex gamma convolution (similar to the representation given by Glasserman and Kim) by a simple moment-matched gamma distribution.
We also perform a review of popular simulation schemes for the Heston model and validate our approach through a simulation study.
The gamma approximation scheme appears to yield small biases on European and Asian option prices when compared to the most popular schemes.
Customer love: Research on the ranking of food and beverage locations
Authors: Bahar Türk , Aysel Erciş
Published: September 2015

Intense competition in today’s markets has meant that customer loyalty is no longer as strong as it used to be. In this context, many researchers have aimed to add new values to the concept of loyalty, particularly focusing on the concept of “love”. This study explores customers’ feelings towards location in order to identify their preferred - or “most loved” - food and beverage locations. A questionnaire was administered to 395 adult customers living in the city centre of Erzurum, Turkey. The fuzzy Shannon’s entropy method is used to identify the weights of each criterion of love, while the fuzzy VIKOR method is used to rank alternative locations. As a result of the analyses, the most prominent expression was found as “I love this location!”, and customers’ most loved places were identified as those serving regional dishes in Erzurum Province, Turkey. The study uses fuzzy numbers to rank alternatives according to the criteria of love. In addition, the ranking is based on degrees of fuzziness by changing the α-cut levels of the fuzzy numbers. The study examines how customers’ preferences between alternatives alter via this change
Viva la Revolución, or: Do Revolutions Lead to More Democracy?
Authors: Boese Vanessa A.
Published: September 2015

There is a vast amount of studies on the origins of revolutions and armed conflict. However, there is no empirical analysis of the political outcome of revolutionary conflicts. A second branch of research focuses on waves of democratization. This paper fills the gap and links the two fields by examining the importance of revolutions as an explanatory factor for changes in systems of governance. Using a data set covering 135 countries from 1960–2011, global changes in the level of democracy are examined. The revolutionary conflicts examined in the panel had a positive influence on a countrys democratic path. In addition the effect of selected variables on the development of the system of governance is analyzed in more detail.

Telemedizin in der grenzüberschreitenden Gesundheitsversorgung am Beispiel transnationaler Teleradiologie
Authors: Rosenberg Britta , Hosten Norbert
Published: September 2015

Telemedizin ist ein Mittel, die politische Zielvorstellung „wohnortnahe Gesundheitsversorgung“ auch in Flächenstaaten zu erfüllen. Schon auf nationaler Ebene kollidiert sie zwar mit dem „Fernbehandlungsverbot“ als Ausdruck eines traditionellen Arzt-Patienten-Verhältnisses, kann aber homogene rechtliche und qualitative Bedingungen voraussetzen. Transnational müssen Qualitätsmaßstäbe ärztlicher Arbeit eingehalten werden, Voraussetzungen (Register, Anerkennung von Qualifikationen) sind jedoch nicht gegeben.

Cenotes – Lakes of the Yucatan Peninsula (Mexico)
Authors: Szeroczyńska Krystyna , Zawisza Edyta
Published: September 2015

Cenote lakes are natural sinkholes or depressions resulting from the collapse of limestone bedrock exposing the groundwater underneath. Thousands of such lakes are particularly encountered on the Yucatan Peninsula (Mexico). These lakes were of great significance for the Maya culture as important religious places and primary source of drink­ing water. They permitted the survival of Mayan communities through dry periods known as “Maya drought”. Most of the cenote lakes are large open water pools measuring tens of meters in diameter. The majority of cenotes are smaller sheliered sites. Their waiers are usually very clear and oligotrophic, originating from rain waier filtering slowly through the ground. The auihors visited and coliected zooplankion samples from eight cenotes in November 2013, namely: Ik-Kil, Samula, Zaci, X-Kekn, Actum Ha, Cristal, Sian Ka’an, and Chan Chemuxil (transect Merida-Tulum- Cancun). The analysed lakes differ considerably in morphological terms, varying from very deep to shallow. Some of them are under human impact (tourists). The water samples were anaiysed for zooplankton content, but the phyto­plankton frequently occurring was also taken into account. The obtained results are largely varied, indicated big eco­logical verity among cenotes which depended on lake age, localization and morphometry. As showed our study Cladocera zooplankion was very rare and only present at several sites. Beiween the fauna community Copepoda and Ostracoda species were the most abundant. Phytoplankton were present in all studied lakes and it sees that played the central role in those ecosystems.

Published: September 2015

The high-pressure behaviour of two representative palmierite-type Pb3(P
x
As1–x
O4)2 ferroelastic compounds with x
= 0 and 0.80 was analyzed by combined single-crystal X-ray diffraction and Raman spectroscopy. Single-crystal diffraction measurements on the As-rich compound Pb3(P0.20As0.80O4)2 show that it undergoes the same macroscopic monoclinic to trigonal phase transition as previously observed in pure Pb3(PO4)2 but with a significantly lower transition pressure, p
c
= 0.90(4) GPa for x
= 0.80 as opposed to p
c
= 1.81(1) for x
= 0.0. Synchrotron X-ray diffraction experiments reveal that both compounds exhibit significant diffuse scattering in a pressure interval of ~1.5 GPa above the corresponding pressure-induced transitions, indicating the persistence of monoclinic nanodomains within the macroscopically trigonal phase above the phase-transition point, similar to the high-temperature structural state. Raman spectroscopy reveal quite distinct lattice dynamics for x
= 0 and x
= 0.80, indicating different pathways of pressure-driven structural alteration. The pure phosphate compound shows a displacive phase transition of thermodynamically second-order type, whereas the As-rich compound exhibits an order-disorder phase transition with multistep structural changes on the mesoscopic scale. The pressure evolution of the Pb phonon modes as well as the broadening of the X-ray diffraction peaks suggests a further pressure-induced phase transition occurring in the range 5–7 GPa for Pb3(P0.20As0.80O4)2, whilst no indication for a second phase transition up to 10 GPa was observed for Pb3(PO4)2.

Influence of Limestone Addition on the Performance of Cement Mortars and Pastes Exposed to a Cold Sodium Sulfate Solution
Authors: Lee S. T. , Hooton R. D.
Published: September 2015

The overall aim of this paper was to establish sulfate resistance of cement mortars and pastes incorporating limestone exposed to severe sulfate attack at 20 and 4°C. Specimens with 0, 10, 20, and 30 % replacement levels of cement by limestone were continually exposed to a sodium sulfate solution with 33,800 ppm of SO42– concentration for 44 weeks. Sulfate exposure tests included compressive and flexural strengths, expansion, and mass loss measurements of mortar specimens. Additionally, in order to identify products formed by sulfate attack, microstructural observations such as X-ray diffraction (XRD) and scanning electron microscopy (SEM) were performed on the paste samples. Experimental results indicated that the mortar specimens incorporating limestone were much more susceptible to sodium sulfate attack compared to those without limestone, especially when exposed to a 4°C sulfate solution. It was found that the main deterioration product of the damaged samples with higher limestone contents was identified as thaumasite, not ettringite or gypsum, by means of XRD and SEM analysis. Furthermore, data on mechanical characteristics confirmed that the sulfate deterioration of mortar specimens was greatly dependent on the replacement levels of limestone.
Engineering Properties of Asphalt Concrete Patching Mixtures
Authors: Chen Jian-Shiuh , Ho Han-Chang , Liao Min-Chih , Wang Tai-Yen
Published: September 2015

Potholes are a visible and annoying form of pavement distress for highway users. One reason for the short life of pothole repairs is that the commonly used patching mixtures cannot withstand the wet weather and the traffic loading. A comprehensive laboratory investigation was performed to evaluate the engineering properties of hot-mix, cold-laid (HMCL) asphalt concrete patching mixtures. The performance characteristics of patching materials was categorized based on four aspects related to initial stability, in-service durability, water resistance, and workability. The engineering properties of HMCL patching mixes were investigated, including Marshall stability, indirect tensile strength, rutting resistance, pothole simulation, and uniaxial compression. Four binders, one aggregate type, two gradations, and one residual binder content were selected for testing in the laboratory. Test results indicated that curing time, nominal maximum aggregate size, temperature condition, and binder type influenced the performance of maintenance materials. The difference in indirect tensile strength among patching mixtures was shown to be high, and the indirect tensile test appeared to be effective in differentiating patching mixtures. A preliminary criterion of the dynamic stability value of more than 1000 cycles/mm was suggested for maintenance materials for rutting resistance. Patching mixtures subjected to loading cycles of 30 or higher to reach 3-mm rut depth under wet conditions in the pothole test were deemed satisfactory in resistance to moisture-induced damage. The patching mixtures tested exhibited good workability at temperatures of 20°C or higher. Test procedures and acceptance criteria developed in this study could be useful as part of a specification to promote quality of bituminous patching mixtures.
Evaluation of Socio-Environmental Effects considering Road Service Levels for Transportation Asset Management
Authors: Han Daeseok , Do Myungsik
Published: September 2015

Internationally, aging infrastructures, tighter budget, and public demands for more accountability have stimulated interests in asset management. Since the old management concept “Worst-First approach” cannot counteract those issues any more, many countries or organizations have developed and operating decision-making support tools, such as Highway Development and Management-4 (HDM-4), RealCOST, HERS, and so on. Nevertheless, the programs missed an important concept of the asset management—the business—which treats the balance among the asset condition, user's satisfaction, and budget demand. The powerful weapon of the business is the level of service (LOS), which is an essential tool for quantification, evaluation, and negotiation. For those reasons, this study tried to suggest a general framework of the LOS-based life cycle cost analysis (LCCA) considering road users and social benefits, and to show its adaptability with empirical application to a Korean case. The case study aimed at the Korean national highway network, and details of sub-models and analysis options followed by the legal investment guideline in Korea. This would be a significant trial, combining engineering, management, economics, accounting, and environmental issues under the single concept of asset management.
The Effect of Aspect Ratio on the Frequency Response of Asphalt Concrete in Impact Resonance Testing
Authors: Boz Ilker , Solaimanian Mansour
Published: September 2015

A comprehensive study was conducted to investigate the influence of aspect ratio (height/diameter) of laboratory specimens on the frequency response of asphalt concrete when tested with impact resonance (IR). Testing was conducted over a range of air voids and temperatures. The IR test, performed in longitudinal mode over 100 cylindrical asphalt concrete specimens, demonstrated that the test is repeatable and reproducible. It was observed that the test response was greatly dependent on the specimen length regardless of the aspect ratio, but the dependency was not noted for specimens with the same diameter of larger aspect ratios. Specimens with the same aspect ratio but different size delivered different resonant frequencies. The test results indicated that the frequency response increased as the aspect ratio increased approximately up to 0.7, and then it decreased with a nonlinear trend as the aspect ratio increased beyond 0.7, indicating the tendency of the frequency response reaching a plateau as the aspect ratio increased. It was inferred from test results that there was a threshold aspect ratio at which the fundamental longitudinal frequency mode was not the dominant frequency mode. Velocity calculations from measured resonant frequencies indicated that the true material properties could be attained at an aspect ratio of as low as 1. Based on the results of this study, testing specimens with a diameter of 150 mm and a height of 170 mm commonly used for producing dynamic modulus test specimens, provided proper size and aspect ratio for testing with IR.

K-complexes (KCs) are thought to play a key role in sleep homeostasis and memory consolidation; however, their generation and propagation remain unclear. The commonly held view from scalp EEG findings is that KCs are primarily generated in medial frontal cortex and propagate parietally, whereas an electrocorticography (ECOG) study suggested dorsolateral prefrontal generators and an absence of KCs in many areas. In order to resolve these differing views, we used unambiguously focal bipolar depth electrode recordings in patients with intractable epilepsy to investigate spatiotemporal relationships of human KCs. KCs were marked manually on each channel, and local generation was confirmed with decreased gamma power. In most cases (76%), KCs occurred in a single location, and rarely (1%) in all locations. However, if automatically detected KC-like phenomena were included, only 15% occurred in a single location, and 27% occurred in all recorded locations. Locally generated KCs were found in all sampled areas, including cingulate, ventral temporal, and occipital cortices. Surprisingly, KCs were smallest and occurred least frequently in anterior prefrontal channels. When KCs occur on two channels, their peak order is consistent in only 13% of cases, usually from prefrontal to lateral temporal. Overall, the anterior–posterior separation of electrode pairs explained only 2% of the variance in their latencies. KCs in stages 2 and 3 had similar characteristics. These results open a novel view where KCs overall are universal cortical phenomena, but each KC may variably involve small or large cortical regions and spread in variable directions, allowing flexible and heterogeneous contributions to sleep homeostasis and memory consolidation.
Hacia una revisión del antropocentrismo kantiano. Argumentos para una consideración ética de la naturaleza (orgánica) según la “Crítica de la Facultad de Juzgar Teleológica”
Authors: Lerussi Natalia Andrea
Published: September 2015

Se analiza la “Crítica de la facultad de juzgar teleológica”, para revisar, mediante tres líneas argumentales, el pretendido antropocentrismo kantiano según el cual los fines del hombre definen los fines de la naturaleza, de modo que esta se ve relegada a mero instrumento. La primera línea muestra cómo el tratamiento de la naturaleza como medio se ve limitado por la moralidad. Las otras dos avanzan más allá del antropocentrismo ético, para rastrear elementos para una ética orientada a la naturaleza (orgánica) donde todos sus miembros se definen también como fines, es decir, como moralmente dignos.
De la posibilidad a la necesidad en el ámbito de la acción. Sopesando las lecturas deterministas e indeterministas de Aristóteles

Se examinan algunos pasajes de Aristóteles para precisar la vinculación entre necesidad y posibilidad en el proceso de la acción humana. Se propone que, dadas las potencias racionales de los seres humanos, cabe decir que el proceso inicia con la tenencia de posibilidades alternativas de acción. El agente, como principio controlador, determina el deseo dominante que ha de activar sus potencias en determinada dirección. La acción se produce luego de manea necesaria.

Published: September 2015

La explicación urbana, definida bajo conceptos psicoanalíticos trascendidos mediante el uso de tópicas complejas en la generación de los problemas urbanos, desarrolla la comprensión de las paradojas de la anti-ciudad en la ciudad, la identidad y la no-identidad, y la marginación y la inclusión. La ciudad es entendida desde el rapport del
ámbito urbano, al descubrir su tópica urbana y subordinar su configuración esencial al urbanismo, en relación con la conciencia colectiva, para explicar y comprender los fenómenos que coadyuvan a entender la identidad, la marginación y la violencia como fenómenos urbanos.

Se examina la interpretación aristotélica del azar como causa accidental en el ámbito de los fines de aquello que puede ser realizado por la naturaleza o por el pensamiento. ¿Por qué un acontecimiento fortuito pertenece al orden de los fines? ¿Qué quiere decir que los sucesos fortuitos son “para algo” (ἓνεκά του)? Se repasan las principales respuestas de los especialistas, se indican algunas deficiencias y se propone una lectura no causal-explicativa de la expresión ἓνεκά του, diferente de la teleología del como-si, como explicación de la finalidad del acontecimiento fortuito.

En este ensayo se presenta parte del resultado del trabajo realizado en la Filial de Ciencias Médicas de Sancti Spíritus, Cuba. Se proponen ideas para el perfeccionamiento de las Prácticas Profesionales y la Educación en el Trabajo del tecnólogo de la salud, como parte de la educación laboral de este profesional. El objetivo de la investigación es diseñar un programa de la Práctica Profesional para ser incluido en la Educación en el Trabajo de los estudiantes de Sistemas de Información en Salud de esta institución. Para cumplir con este objetivo se realizó una revisión de la documentación establecida para la realización de las prácticas profesionales, los momentos de la carrera y el tiempo planificado en las mallas curriculares. Se pudo constatar que la organización y planificación del proceso podría no estar aportando en la formación de competencias y habilidades requeridas de este profesional. Esta problemática constituye preocupación del colectivo pedagógico dado los aportes que desde las ciencias básicas se pueden dar a los profesionales de esta carrera. El uso de la tecnología en el aprendizaje como recurso didáctico en la formación del tecnólogo es cada vez más frecuente, sin embargo existe un estado de insatisfacción generalizado sobre el diseño de las Prácticas Profesionales.
Comparación de prácticas inclusivas de docentes de servicios de educación especial y regular en México

Published: September 2015

Las prácticas inclusivas buscan atender a toda la población estudiantil, independientemente de sus características. En el presente artículo se comparan las prácticas docentes de escuelas regulares con apoyo de educación especial (ER-USAER) y las escuelas especiales, llamadas Centros de Atención Múltiple (CAM), para conocer dónde se le brinda una atención más inclusiva a la población infantil con discapacidad. Se trabajó con 15 docentes de CAM y 17 de ER-USAER de tres estados de México, a quienes se aplicó la Guía para la Evaluación de las Prácticas Inclusivas en el Aula (GEPIA) en su versión de auto-reporte y observación. Los resultados del auto-reporte muestran que las y los docentes de ER-USAER trabajan de manera colaborativa con profesionales de Educación Especial, mientras los de CAM prefieren el trabajo independiente. Los resultados de la observación indican que la planta docente de CAM tiene más prácticas inclusivas que sus pares de ER-USAER, lo cual parece explicarse por sus condiciones de trabajo –reducido número de estudiantes por grupo y cultura escolar- y sus conocimientos sobre discapacidad. Los docentes de ER-USAER no siempre planean considerando a todos los alumnos.

Published: September 2015

El presente artículo expone los resultados de una investigación realizada en el año 2014, en la Facultad de Educación de la Universidad Bernardo O´Higgins. Esta apuntaba a describir las características,  motivaciones y expectativas  que impulsaron a un grupo de jóvenes (varones) a estudiar carreras pedagógicas. La metodología utilizada es de tipo cuantitativa descriptiva, considerando un cuestionario, que luego de su validación y pilotaje (Alfa Crombrach de 0.83), fue aplicado a 42 estudiantes. Los resultados obtenidos de su procesamiento permiten señalar que en su mayoría los estudiantes, han egresado recientemente del colegio, presentando un rendimiento académico en la media nacional y proviniendo, un tercio de ellos, de familia de profesores. En relación a la visión que tienen del sistema educativo, se aprecia que dan una baja valoración a la educación subvencionada por el Estado, cuestionan la labor docente de sus profesores de colegio, tienen serios reparos respecto a la preparación de la enseñanza y a la pertinencia de los contenidos de la educación secundaria y consideraran que la sociedad otorga una baja valoración al trabajo de los profesores. Prevalece en ellos la motivación intrínseca por sobre la extrínseca, lo que permite establecer que los estudiantes que ingresaron, orientaron su decisión en función de intereses propios del campo educativo, prevaleciendo en ellos la vocación de ser maestros, a pesar del momento controversial que vive la carrera magisterial en Chile.

Published: September 2015

Pristimantis divnae is a nocturnal, semi-arboreal species found in lowland forests of southern Peru in the departments of Cusco, Madre de Dios and Puno. Here, we present a 382 km geographical range extension and the first record at 980 m elevation, increasing the known vertical distribution by 678 m. This is also the first record of this species from premontane forest, suggesting that habitat requirements of P. divnae are broader than originally anticipated.
Christianity and the Shaping of Vanuatu's Social and Political Development
Authors: Clarke Matthew
Published: September 2015

The Pacific island state of Vanuatu has been considerably shaped by its Christian heritage. Indeed, the role of the various Christian Churches has been pivotal in the development and sustenance of Vanuatu prior to and since its Independence. These Churches include Anglican, Catholic, Pentecostal and evangelical denominations. Missionaries and later local Church leaders were involved directly in Independence movements and shaped the legal and social infrastructure of this nation. This involvement and influence has continued to the present. This article will consider the role the Church has played in the development of Vanuatu. First, a case study analysis of both the historical and contemporary role the Church has played in the development of Vanuatu will be presented. This review will consider the impact of both key individual Church leaders who played central roles in Vanuatu’s Independence. Secondly, the paper will consider the contemporary role Christian Churches play in the provision of social service—including education and health—across Vanuatu. It will conclude that Christianity has therefore played and continues to play a central role in the political and social development of Vanuatu.
‘Where you once belonged’
Authors: McGrath James
Published: September 2015

While Lennon and McCartney’s class affiliations are ambiguous to degrees that should remain debatable, the depth and the detail in which working-class life defines their work have been overlooked, thus misrepresenting The Beatles’ cultural significance. As Collins (2012) critiques, initial New Left criticisms of The Beatles – almost exclusively in response to one composition, ‘Revolution’ (1968) – have recently been adapted by commentators eager to portray The Beatles as a culturally and politically conservative force. I argue that early Left-wing and recent Right-wing criticisms of The Beatles’ legacy are misleading, because both overlook Lennon and McCartney’s different relationships to working-class culture. I also emphasize an importantly related, even more marginalized aspect of The Beatles’ history: the significance of black musical and cultural influences from Liverpool. The article seeks to offer new interpretations of songs including ‘Norwegian Wood’, ‘A Day in the Life’, ‘Revolution’, ‘Ob-la-di, Ob-la-da’ and ‘Working Class Hero’.

Studies addressing the estimation of genetic parameters in soybean have not emphasized the epistatic effects. The purpose of this study was to estimate the significance of these effects on soybean grain yield, based on the Modified Triple Test Cross design. Thirty-two inbred lines derived from a cross between two contrasting lines were used, which were crossed with two testers (L1 and L2). The experiments were carried out at two locations, in 10 x 10 triple lattice designs with 9 replications, containing 32 lines (Pi ), 64 crosses (32 Pi x L1 and 32 Pi x L2 ) and controls. The variation between ( ͞L1i + ͞L2i - ͞Pi ) revealed the presence of epistasis, as well as an interaction of epistasis x environment. Since the predominant component of epistasis in autogamous species is additive x additive (i type), we suggest postponing the selection for grain yield to later generations of inbreeding in order to exploit the beneficial effects of additive x additive epistasis.

Published: September 2015

A aparência de uma imagem radiográfica digitalizada é de extrema importância para uma correta interpretação e conseqüentemente, um efetivo diagnóstico. Objetivo: Sabendo-se que são vários os fatores que podem influenciar a qualidade de uma imagem digitalizada, variáveis aplicadas durante o processo de digitalização foram analisadas, a fim de eliminar possíveis interferências negativas. Metodologia: Os parâmetros avaliados incluíram a resolução espacial da imagem e a modalidade de captura. A repercussão dessas variáveis no alcance dinâmico de imagens digitalizadas foi analisada pelo programa Photoshop (Adobe Systems Incorporated, Mountain View, Califórnia, EUA). Resultados: Foi possível perceber que para as radiografias digitalizadas indiretamente, uma resolução espacial muito superior não é requerida. Conclusão: A proporção sinal/ruído (signal/noise ratio – SNR) não deve ser negligenciada para as imagens digitais.
Variações anatômicas do processo coronóide em mandíbulas de adultos dentados, desdentados totais e desdentados parciais
Authors: Telles Márcia Pinheiro , De Almeida-Júnior Erasmo
Published: September 2015

Objetivo: Avaliar a correlação entre as alterações de formato do processo coronóide e a perda parcial ou completa de unidades dentárias em mandíbulas secas de adulto, levandose em consideração o sexo. Metodologia: Foram analisadas 198 mandíbulas secas de adulto humano de ambos os sexos, divididas em três grupos. O primeiro grupo foi constituído por mandíbulas com presença de todas as unidades dentárias (68 mandíbulas); o segundo, por mandíbulas com edentulismo parcial (79 mandíbulas) e o terceiro por mandíbulas edêntulas (50 mandíbulas). A análise do formato foi realizada mediante observação visual e anotação em ficha padronizada. Resultados: Pôde-se constatar que a ausência de dentes, tanto em mandíbulas do sexo feminino quanto do masculino, provocou alteração no processo coronóide que passou do tipo  arredondado em mandíbulas com presença de todas as unidades dentárias para o tipo foice nas mandíbulas edêntulas. Nas parcialmente desdentadas, o tipo arredondado foi o mais freqüente no sexo masculino, ao passo que o tipo foice foi o mais freqüente no sexo feminino. Conclusão: A ausência de unidades dentárias seja parcial ou total, contribuiu para a modificação do formato do processo coronóide, porém sem diferenças estatisticamente significativas entre os sexos.
Considerações odontológicas em pacientes portadores de anemia falciforme
Authors: Lima Rafael Guimarães , Martinez Marcelo Gonçalves , Sardinha Sandra de Cássia Santana
Published: September 2015

A anemia falciforme é uma doença sanguínea genética caracterizada por uma mutação no gene da hemoglobina, gerando uma molécula anormal de hemoglobina (HbS). Esta forma irregular dificulta sua passagem pela rede sangüínea, resultando em crise dolorosa, cansaço e falta de apetite.  Algumas vezes as células anormais bloqueiam o fluxo de sangue aos tecidos e órgãos, gerando dor, caracterizando as crises falcêmicas. Esta dor pode sertão intensa ao ponto de levar ao internamento do paciente. Devido à presença de vasos sangüíneos em todas as partes do corpo as lesões podem acontecer em qualquer local. A proposta deste trabalho é abordar as principais manifestações gerais e bucais encontrados em indivíduos portadores da doença.
PERIODONTITE AGRESSIVA: REVISÃO DE LITERATURA
Authors: Barbosa Renata De Araújo , Souza Sandro Bittencourt , Ribeiro Érica Del Peloso
Published: September 2015

A periodontite agressiva (PAg) acomete indivíduos clinicamente saudáveis, exceto pela presença da doença periodontal, caracterizando-se por rápida perda de inserção e destruição óssea e ainda pela agregação familiar, dentre outras características secundárias. A rápida destruição periodontal presente na PAg é um fator de extrema importância e desperta a atenção de pesquisadores em todo o mundo, uma vez que se deparam com uma infecção caracterizada por uma microbiota altamente virulenta e/ou um alto nível de susceptibilidade do indivíduo. O risco de perdas dentárias e comprometimento da função e estética, principalmente em pacientes jovens, mais comumente acometidos pela PAg, também estimulam a busca por respostas e tratamentos mais eficientes no controle da doença. Diante disso, o objetivo deste trabalho foi realizar uma revisão de literatura sobre a periodontite agressiva abordando as descobertas sobre a etiologia microbiana e susceptibilidade do indivíduo, assim como sua resposta às diferentes abordagens terapêuticas.
