Authors: Benli Ozdemir Esra , Hamzaoglu Ergin
Published: November 2016

The main purpose of this study is to explore the effect of the Common Knowledge Construction Model (CKCM) on the academic achievement and attitude towards science of primary education students in science topics. The group in this study consists of 87 students from four different classrooms of 7 th and 8th grades. This study in which the integrated design of the mixed method. Science and Technology class was taught based on the CKCM in the experimental group and 5E learning cycle was applied in the control group. Data of the study were obtained as a result of conducting the academic achievement tests, attitude towards science test, views on phenomenographic categories, classroom observation notes, video records. As a result, the students of the 7th grade were effective on improving the studentsâ€™ developing their academic achievement. On the other hand, the students of the 8th grade were led to a medium level improvement in developing the viewpoints of the students on academic achievement. 7th and 8th grade Science and Technology lessons taught based on CKCM were not effective on improving the studentsâ€™ developing their attitude towards scÄ±ence.  It was observed that concepts taught based on phenomena are considered more meaningful and perceived more easily by the students. 

 

Key words: common knowledge construction model, 5E learning cycle model, academic achievement and attitude towards science.
Green Extraction Technique: Subcritical Water Extraction
Authors: Anurukvorakun Oraphan
Published: November 2016

An environmental kindly technique, subcritical water extraction (SWE) are based on using water as extraction solvent at temperatures between 100 Â°C and 374 Â°C.Â  Increasing the temperature at moderate pressure also reduces the surface tension and viscosity of water causes the polarity of subcritical water is comparable to organic solvents.Â  Therefore, the subcritical water could be improved the competency for the extraction.Â  The aim of this work was to study the flavonoid content of Emilia sonchifolia (L.) using different extraction procedures (SWE and the traditional extraction or ethanolic extraction).Â  The results revealed that quercetin, a plant-derived flavonoid, was a major component in both extraction procedures.Â  The use of SWE provided higher quercetin content and antioxidant activity.Â  Quercetin content by SWE and traditional extraction were 45.92 mg/ml and 39.94 mg/ml, respectively.Â  The EC50 (Effective Concentration, 50%) of SWE and traditional extraction were 496 and 555.67 mg/ml, respectively.Â  Additionally, this work demonstrated that the traditional time-consuming techniques for 12 hours of the extraction of flavonoids could be substituted for the SWE technique within 1 hour.Â  Consequently, the capability of SWE technique was elaborately evaluated and revealed on this work.Â  Â Keywords: Subcritical water; Emilia sonchifolia (L.)
Learning scenarios in SAP for wind turbines manufacturing
Authors: Prostean Gabriela , Vasar Cristian , Giuca Olivia
Published: November 2016

The paper presents a conceptual model of learning scenarios in SAP, so that it is easily assimilated by students who still do not have direct contact with activities in the economic environment. The case study is configured for different planning situations acquisitions, necessary for obtaining the raw materials for wind turbines, more specifically for obtaining the generator, which is a standard equipment. The different scenarios presented in the conceptual model are designed, that itâ€™s not as easy to increase the nacelle, respectively the generator manufacturing capacity as it is with other components. Based on this model, the students can learn to work both with concrete transactions of â€œPurchase ordersâ€ for certain and isolate orders and as well with transactions of a â€œScheduling agreementâ€ for firm orders that last long periods of time. This model demonstrates that the challenge of any new processes of generator manufacturing can be defined in SAP (Systems, Applications, and Products), as one of the main providers of the ERP (Enterprise Resource Planning) software package.

Cilj ovog istraživanja bio je evaluacija programa prevencije poremećaja ishrane (Dalle Grave & De Luca, 1999) na prigodnom uzorku adolescentkinja u Srbiji. Ovaj program ima za cilj povećanje znanja o poremećajima ishrane, kao i redukciju ponašanja i navika povezanih sa poremećajima ishrane. U istraživanju su učestvovale 84 učenice, od čega je 57 učenica pohađalo program, a 37 učenica su činile kontrolnu grupu. Prosečna starost ispitanica u uzorku bila je 14.92 godina, a prosečan Indeks telesne težine (BMI) iznosio je 20.02. Primenjeni program prevencije trajao je ukupno šest nedelja i obuhvatio je šest susreta u trajanju od 90 minuta. Baterija upitnika samoprocene je zadavana grupi koja je učestvovala u programu i kontrolnoj grupi pre implementacije programa, kao i šest meseci nakon njegovog sprovođenja. Primenjeni su sledeći instrumenti: Upitnik za procenu ponašanja i navika povezanih sa poremećajima ishrane za adolescente (ChEAT), Upitnik procene samopoštovanja (SES), Upitnik za procenu učestalosti sprovođenja dijeta kod adolescenata (ADS), kao i Test znanja o poremećajima ishrane, konstruisan za potrebe ovog istraživanja. Analiza podataka upućuje na značajan efekat grupe, kao i efekat interakcije vremena i grupe u ispitivanom nivou znanja. Rezultati istraživanja pokazuju da su šest meseci nakon sprovođenja programa ispitanice koje su učestvovale u programu pokazale značajno viši nivo znanja o poremećajima ishrane i njihovim uzrocima u odnosu na ispitanice iz kontrolne grupe. Nisu dobijene značajne razlike između grupa na bihejvioralnom planu. Autori zaključuju da program namenjen prevenciji poremećaja ishrane u školi može biti veoma koristan, jer se pokazao kao uspešan u povećanju nivoa znanja učesnika o rizicima za pojavu poremećaja ishrane.
ODNOS KREATIVNOSTI I TENDENCIJE KA ISPOLJAVANJU PSIHOPATOLOŠKIH SIMPTOMA U SVETLU MODELA ZAJEDNIČKE VULNERABILNOSTI
Authors: Novakov Ivana , Novović Zdenka
Published: November 2016

U ovom radu prikazano je istraživanje koje se bavilo pitanjem odnosa kreativnosti i psihopatologije. Polazna osnova istraživanja bile su postavke modela zajedničke vulnerabilnosti, koji odnos između kreativnosti i psihičkog poremećaja objašnjava uz pomoć tri grupe varijabli: a) protektivnih faktora (visoka inteligencija, dobar kapaciteti radne memorije i visoka kognitivna fleksibilnost), b) riziko-faktora (slabije intelektualno funkcionisanje, niži kapacitet radne memorije i manja kognitivna fleksibilnost) i c) faktora zajedničke vulnerabilnosti (snižena latentna inhibicija, otvorenost ka novinama i hiperkonektivnost koja se ogleda u tendenciji ka sinestetskim iskustvima). Istraživanje je sprovedeno na uzorku od 151 ispitanika, starosti od 18 do 22 godine. Primenjeni su zadaci iz Instrumenta za ispitivanje divergentne produkcije, upitnik prisustva psihopatoloških simptoma CORE-OM, Ravenove progresivne matrice za napredne (set II), skala Otvorenosti prema iskustvu iz Inventara velikih pet (BFI), adaptirana verzija Testa pravljenja traga (TMT) i suptest Šifra iz VITI-a. U svrhu ovog istraživanja konstruisani su i instrumenti za merenje tendencije ka sinestetskim iskustvima i latentne inhibicije. Sprovedene su dve hijerarhijske regresione analize, a rezultati su pokazali da se kao značajni prediktori kreativnosti ističu Otvorenost prema iskustvu, tendencija ka sinestetskim iskustvima i u negativnom smeru latentna inhibicija, dok se kao marginalno značajan prediktor ističe efikasnost radne memorije. Kao značajan prediktor psihopatologije izdvojila se sklonost ka sinestetskim iskustvima, dok se kao marginalno značajan prediktor u negativnom smeru izdvaja radna memorija. Rezultati delimično pružaju podršku postavkama modela zajedničke vulnerabilnosti, ali otvaraju i neka nova pitanja vezana za eventualno proširivanje modela i buduća istraživanja u ovoj oblasti.
Desempenho universitário no Brasil: estudo sobre desigualdade educacional com dados do ENADE 2014
Authors: Crepalde Neylson João Batista Filho , Silveira Leonardo Souza
Published: November 2016

O ensino superior brasileiro passou por etapas de expansão e diversificação ao longo das últimas duas décadas. A literatura sociológica, por sua vez, demonstra que as desigualdades educacionais podem estar associadas a diferentes níveis, a saber, individual e institucional. O presente trabalho analisa como se comportam estas desigualdades com relação ao desempenho dos alunos quando investigadas de forma desagregada por cursos de nível superior e quando controladas por instituição. Além disso, investigamos ainda a diferença de desempenho dos alunos de instituições de categorias administrativas diferentes considerando o “efeito escola”. Para tanto, usamos os dados do Enade 2014 e estimamos modelos lineares por mínimos quadrados ordinários e modelos hierárquicos. Nossos principais achados podem ser resumidos da seguinte forma: 1) o efeito das escolas sobre o desempenho dos alunos supera as diferenças de desempenho por sexo, raça e renda familiar; 2) as desigualdades se comportam de maneira distinta em cada curso chegando, algumas, a desaparecer.
A Multi-Focus Image Fusion Algorithm Based on Contrast Pyramids
Authors: Lai Mingzhu , Sun Jianguo , Zhang Liguo , Shen Yiran , Yang Qing , Jin Zilong
Published: November 2016

This paper proposes a new approach for multi-focus images fusion based on Region Mosaicing on Contrast Pyramids (REMCP). A density-based region growing method is developed to construct a focused region mask for multi-focus images. The segmented focused region mask is decomposed into a mask pyramid, which is then used for supervised region mosaicking on a contrast pyramid. In this way, the focus measurement and the continuity of focused regions are incorporated and the pixel level pyramid fusion is improved at the region level. Objective and subjective experiments show that the proposed REMCP is more robust to noise than compared algorithms and can fully preserves the focus information of the multi-focus images meanwhile reducing distortions of the fused images.
The Telomerase-Derived Anticancer Peptide Vaccine GV1001 as an Extracellular Heat Shock Protein-Mediated Cell-Penetrating Peptide
Authors: Kim Hong , Seo Eun-Hye , Lee Seung-Hyun , Kim Bum-Joon
Published: November 2016

Cell-penetrating peptides (CPPs), a group of small peptides capable of promoting the transport of molecular cargo across the plasma membrane, have become important tools in promoting the cellular uptake of exogenously delivered macromolecules. GV1001, a peptide derived from a reverse-transcriptase subunit of telomerase (hTERT) and developed as a vaccine against various cancers, reportedly has unexpected CPP properties. Unlike typical CPPs, such as the HIV-1 TAT peptide, GV1001 enabled the cytosolic delivery of macromolecules such as proteins, DNA and siRNA via extracellular heat shock protein 90 (eHSP90) and 70 (eHSP70) complexes. The eHSP-GV1001 interaction may have biological effects in addition to its cytosolic delivery function. GV1001 was originally designed as a MHC class II-binding cancer epitope, but its CPP properties may contribute to its strong anti-cancer immune response relative to other telomerase peptide-based vaccines. Cell signaling via eHSP-GV1001 binding may lead to unexpected biological effects, such as direct anticancer or antiviral effects. In this review, we focus on the CPP effects of GV1001 bound to eHSP90 and ehsp70.
Sonar for Environmental Monitoring: Construction of a Multifunctional Active Acoustic Platform Applied for Marine Renewables
Authors: Francisco Francisco , Sundberg Jan
Published: November 2016

Marine renewable energy is emerging as one of the fast-growing industry in the last decades, as modern society pushes for technologies that can convert energy contained from winds, waves, tides and stream flows. The implementation of renewable energy technologies impose high demands on both structural and environmental engineering, as the energy converters have to work under extreme conditions where parameters such as sea-bottom configuration, water transparency and depth, sea-states and prevailing winds are harsh. Constant monitoring of the marine environment is crucial in order to keep this sector reliable. Active acoustics is becoming a standard tool to collect multi-dimensional data from physical, geological and biological properties of the marine environment. The Div. of Electricity of Uppsala University have been developing an environmental monitoring platform based on sonar systems. This platform aims to monitor the installation, operation and decommissioning of marine renewable energy converters. The focus will be given the observations of behaviors of marine animals in vicinity of energy converters but also structural inspection and monitoring of MRETs. This paper describes how this multifunctional environmental monitoring platform come to existence from the design to the deployment phase.

Published: November 2016

The whole process of aluminum cycle consists of four stages: Production of alumina and primary aluminum, fabrication and manufacture of aluminum products, use of aluminum final products, and recycling of obsolete aluminum products. Aluminum cycle in China in 2011 was analyzed using alumium flow diagram, and the following indices were obtained: The resource self-support ratio of alumina, aluminum and the whole aluminum industry were 53.18%, 95.58% and 54.85%, respectively; self-produced and net imported aluminum scrap use ratios of the aluminum industry were 4.68% and 7.98%, respectively. Aluminum cycles and aluminum flow indices in China of the year 1990, 1995, 2000, 2005 and 2008–2010 were also analyzed. It was found that from 1990 to 2011, imported Al-containing resources increased and imported bauxite has increased significantly since 2005. Resources self-support ratio of aluminum industry changed gradually from fully self-support to depencdent on the imports of raw materials. Self-produced auminum scrap use ratio presented downtrend basically and the imported aluminum scrap use ratio was greater than self-produced aluminum scrap use ratio after 1995.

Authors: Shi Chengdong , Zhou Guanglu , Bian Dunxin , Wu Meixiang
Published: November 2016

Consider a closed-loop supply chain including a manufacturer, a retailer and two third party recyclers as the background. A coordination and optimization model is built by using the downside-risk function, Cournot model and government subsidy excitation function. The effect of risk characteristics, government subsidy and Cournot competition on supply chain is analyzed, and the impact of revenue-and-expense sharing contract is studied in the channel, which shows that the contract cannot coordinate and optimize the closed-loop supply chain. Also, risk sharing contract and expense sharing contract are designed, which can offer the desired downside protection to the retailer, provide more profits to the agents, and accomplish channel coordination and optimization. Moreover, an application example is given for testing the effectiveness and feasibility of the contract, and the bound and rule of the contract parameters are given. Finally, by the analysis of numerical simulation and sensitivity of the model based on the contract, the validity and practicability of the model are verified, and the relationship between government subsidy, risk characteristics, competitive characteristics with the supply chain is obtained. This study provides decision support and decision-making reference for the development of remanufacturing industry.
Multi-Period Mean-Absolute Deviation Fuzzy Portfolio Selection Model with Entropy Constraints
Authors: Zhang Peng , Gong Heshan , Lan Weiting
Published: November 2016

This paper considers a multi-period fuzzy portfolio selection problem maximizing the terminal wealth imposed by risk control, in which the returns of assets are characterized by fuzzy numbers. A fuzzy absolute deviation is originally defined as the risk control of portfolio. Entropy constraints and borrowing constraints are added in the portfolio selection model. Based on the theories of possibility measures, a new multi-period portfolio optimization model with transaction costs is proposed. And then, the proposed model is transformed into a crisp nonlinear programming problem by using fuzzy programming approach. Because of the transaction costs, the multi-period portfolio selection is the dynamic optimization problem with path dependence. Through changing the cost function into a variable, the multi-period portfolio selection is approximately turned into the dynamic programming. Furthermore, the discrete approximate iteration method is designed to obtain the optimal portfolio strategy. Finally, an example is given to illustrate the behavior of the proposed model and the designed algorithm using real data from the Shanghai Stock Exchange.
AEWMA t Control Chart for Short Production Runs
Authors: Chang Zhiyuan , Sun Jinsheng
Published: November 2016

Owing to the limited number of inspections during a short run process, it is impossible to get the correct estimate of the population mean and standard deviation during Phase I implementation of control chart. Thetcontrol chart proposed recently can overcome this problem. The EWMAtcontrol chart has been proposed to monitor the process mean, but a single EWMAtcontrol chart cannot perform well for small and large shifts simultaneously, which is known as the “inertia problem”. The adaptive varying smoothing parameter EWMA (AEWMA) control chart can overcome the inertia problem. In this paper, the AEWMAtcontrol chart for short run process is proposed. The truncated average run length and the probability of trigger a signal are adopted to test the performance of short run AEWMAtchart. Based on the investigation of the joint effect of control chart parameters on the performance of AEWMAtchart, a new optimization algorithm is proposed for statistical design of the AEWMA control chart. Simulations are performed for perfect and imperfect setup conditions, the results show that the AEWMAtcontrol chart performs better than the EWMAtcontrol chart.
Mempertahankan Sorga di Delang: Dilema Sawit dan Hutan
Authors: Simon John Christianto
Published: November 2016

The ecological issue has become crucial and urgent problem to be responded the logically and practically. This very issue is inseparable from a challenge in the form of catastrophic convergence: poverty, injustice, and violence. Analysis on the ecological problem brought us to trace back the problem of thought contributed by certain philosophical and thelogical thought. It has given birth to an absolute anthropocentrism which has been consolidated by certain theology and in turn gave birth to an expansive notion by way of the mastery over nature, even over other human fellow. The absolutisation of ratio brought about the birth of capitalism (globalized imperialism), which in turn created man as homo oeconomicus in which its keyword is injustice. In the middle of the impoverishing massive ecological damage, there is a different story that showed a local community's ability in defending the environmental conservation. A small village, Kudangan, in Delang Subdistrict are in agreement "Defending Delang's Forest against Palm Oil Plantation Expansion"�. Theologically, the Delang's local community see nature (forest) not only as something with economical value, but as a "home" for the Divine. The Divine abide in hills with its leafy trees in Delang's area. Here, a contextual theology taking into account the local religiosity instilment to help us rediscovering our contextual mission, that which taking into account the primal worldview (read: cosmic religion), whose principal value is be friendly toward nature.

We present a case demonstrating a previously undescribed use for the Cook Staged Extubation Set (Cook SESTM) via a tracheostomy stoma following decannulation of tracheostomy in a 64‐year‐old male 'at risk' patient. Our experience demonstrates that the Cook SES may be used via a tracheostomy stoma in addition to its described use via the oral route.
Isolation and characterization of algicidal bacteria and its effect on a musty odor-producing cyanobacterium Dolichospermum crassum in a reservoir
Authors: Shimizu Taketoshi , Oda Takuya , Ito Hiroyuki , Imai Ichiro
Published: November 2016

Algicidal bacteria that attack Dolichospermum crassum were isolated from the Karasuhara Reservoir in October 2010. Phytoplankton monitoring was performed from April 2010 to March 2011, and D. crassum was detected from August to November. At its peak frequency (in early October), it accounted for 23% of all phytoplankton cells. Heterotrophic bacteria were isolated from the surface water, and an algicidal assay was conducted. As a result, 3 out of 47 bacterial strains showed strong algicidal activity, and they completely destroyed the trichomes of D. crassum. An initial inoculation dose of only 1.0 × 102 cells ml−1 of these strains was enough to digest D. crassum. These strains were identified as Rheinheimera spp. according to 16S rDNA sequence analyses. This is the first report about algicidal bacteria that attack D. crassum. Algicidal bacteria could be key agents for controlling D. crassum in reservoirs.
Effect of baffles on the hydraulic performance of sediment retention ponds
Authors: Khan Sher , Melville Bruce W. , Khan Mudasser Muneer , Shoaib Muhammad , Shamseldin Asaad
Published: November 2016

An investigation of the effect of baffles on retention pond performance using a physical model of an existing sediment retention pond is presented. Analysis of residence time (RTD curves) was used to compare the hydraulic performance of different arrangements of baffles in the pond. Five different arrangements for the design of baffles were studied. The results show that placing a single baffle to deflect the influent to a sediment retention pond does not improve pond performance; rather, it stimulates short-circuiting. This is contradictory to the literature and is considered to be a consequence of the model pond incorporating sloping walls, which is a novel aspect of this study. Most of the previous studies have neglected the effects of battered walls. Conversely, the inclusion of more than two baffles was found to increase the hydraulic performance. The results reported here are limited to small and narrow ponds where a large portion of the pond is batter (i.e. made up of sloping walls). For large area ponds, batter effects may be negligible and are likely to be different from those reported here.
The response of phytoplankton and microlayer-adapted bacteria to monolayer application in a humic, eutrophic irrigation dam
Authors: Pittaway P. , Matveev V.
Published: November 2016

Repeat applications of artificial monolayers to farm irrigation dams to reduce evaporative loss may adversely affect water quality by enhancing populations of microlayer-adapted bacteria and blue-green algae. The microlayer, subsurface and water column of a 16 ha dam were monitored every two weeks for 18 months, to benchmark the seasonal dynamics of phytoplankton and microlayer-adapted bacteria prior to monolayer application. Results for Secchi depth, total P, total N, chlorophyll a, phytobiovolume and UV254 absorbance, characterise Logan's Dam as humic and hypereutrophic. Seasonal peaks in the cyanobacterial species Microcystis aeruginosa and Anabaena sp. associated with regular thermal stratification periods over summer, exceeded the Queensland algal bloom alert level. Dissolved organic matter derived from aromatic char in the black soil used to construct the dam was the main substrate for microlayer-adapted bacteria. Intermittent monolayer application over seven weeks in late summer temporarily increased surface pressure, indicating a condensed monolayer had formed, with no increase in chemical oxygen demand or in populations of cyanobacteria or microlayer-adapted bacteria. The increase in dissolved organic carbon was well below the concentration recorded after a pump ingress event in late spring. In this humic hypereutrophic irrigation dam, repeat applications of the experimental monolayer formulation did not adversely affect water quality.
The Imperial Discourse and Roger’s Tragic Death in “Aloewood Incense: Second Burning”
Authors: Guanyu Qin , Meng Qiao
Published: November 2016

Some scholars hold that Roger’s death in “Aloewood Incense: Second Burning” (1943) was caused by the repulsion from his colleagues and students, this paper, however, maintains that the imperial discourse regarding sexuality and the grand design of colonialism deprived Roger of a sense of belonging in Hong Kong and marginalised him, leaving him with nothing but alienation within the diasporic community and no choice but death. Chang’s exposure of the devastating effect of imperial discourse on its expatriates denounced the superiority of the western culture, indicating her sharp vision as an intellectual.
ABC Traffic Light: A Health Education Tool

Published: November 2016

It is during the childhood period of one’s life trajectory that the exponential increase of vocabulary
acquisition occurs. In Portugal, language disorders are the most frequently seen child development
impairments, affecting 3 to 15 per cent of children under six years. Because delays in the acquisition of
basic vocabulary can compromise inter-peer relational communication, a timely therapeutic
assessment and intervention becomes all the more crucial. A speech therapy ludic-pedagogic
intervention tool—the ABC Traffic Light—was created so as to aid in promoting basic vocabulary
acquisition in children aged between three and six years. It consists in a traffic light with three built-in
pouches, each of which containing cards suggestive of activities of varying difficulty levels. The
empirical range of the proposed tool in the context of speech therapy assessment and intervention
sessions should be highlighted.

La Unam y la Escuela Central de Artes Plásticas durante la dirección de Diego Rivera
Authors: González Mello Renato
Published: November 2016

Entre agosto de 1929 y mayo de 1930, Diego Rivera estuvo al frente de la institución sucesora de la Academia de San Carlos. Su presunta modernización proletarizante y vanguardista, así como el supuesto coservadurismo de sus oponentes, son analizados con base en una documentación nunca antes empleada, gracias a la cual es posible advertir las paradojas latentes en uno y otro proyectos educativos. Asimismo, queda de manifiesto el vínculo entre la ideología del maximato y el pensamiento estético de Rivera, el cual debería a aquélla más de lo que hasta ahora se ha pensado.
Anotaciones sobre el origen del arte coreográfico y su posible dinámica en México
Authors: Dallal Alberto
Published: November 2016

Aún antes de la profesionalización de las diversas actividades dancísticas, la composición coreográfica desempeñó un papel fundamental en todos los fenómenos dancísticos. En el México prehispánico, la tarea coreográfica estuvo en manos de los sacerdotes, quienes imprimieron el sentido ritual y altamente simbólico que, todavía en la actualidad, tienen las danzas indígenas. La conquista española, a su vez, no hizo sino encauzar tales prácticas en un marco cristiano.
El legado de Luis Barragán y la renovación de la cultura
Authors: Aldrete-Haas José Antonio
Published: November 2016

Este artículo es una semblanza muy detallada de la obra del jalisciense Luis Barragán. En especial, enfatiza su carácter sintético: la vanguardia de principios de siglo, la arquitectura rural mexicana y aun soluciones regionales como los cashbas del norte de África, fueron reunidas en una propuesta que ante todo pretendía ofrecer tranquilidad y paz a los espacios domésticos y religiosos. La integración de esos elementos en una propuesta a la vez local y mundial es lo que constituye el principal valor de la obra de Barragán.
El exemplum como estrategia persuasiva en la Rhetorica christiana (1579) de fray Diego Valadés
Authors: Carrasco M. Rolando
Published: November 2016

En este ensayo, el autor plantea la necesidad de profundizar en la complejidad discursiva de la Rhetorica christiana desde una relectura de sus estrategias argumentativas. Estrategias que se encuentran lo mismo en los planteamientos que en los ejemplos ofrecidos por el fraile franciscano, tanto en la preceptiva oratoria puesta de relieve como en los grabados realizados expresamente para la obra. Rolando Carrasco analiza la importancia que tienen los exempla en su función retórica, puesto que su carácter vivencial les otorga un valor argumentativo de carácter probatorio, como en la mejor tradición jurídica heredada del mundo clásico grecolatino.Por tanto, el lector podrá corroborar que la obra de fray Diego Valadés no sólo tiene una enorme significación literaria, sino también un enorme valor como alegato de orden teológico y jurídico que fue necesario esgrimir en un momento preciso de la historia, cuando se estaba gestando la incorporación de los nativos americanos al mundo occidental.
Arte y ciencia a través de las imágenes de aves en la pintura mural prehispánica
Authors: Navarijo Ornelas María de Lourdes
Published: November 2016

Lourdes Navarijo examina las modalidades de representación gráfica de las aves en la pintura mural prehispánica. Aun cuando existen numerosos ejemplos en la arquitectura, la cerámica y otros objetos de uso común, lo cual atestigua la importancia de las aves en las culturas precolombinas, este estudio se concentra en la pintura. Tomando como base ejemplos de Teotihuacan y de cinco sitios arqueológicos más de la zona maya, la autora intenta explicar el papel de las aves como signos o metáforas de un complejo lenguaje pictórico, que tiende más a la alegoría. La precisa utilización de las aves en este lenguaje, según las cualidades particulares de cada especie, revela un enorme conocimiento ornitológico y ambiental de los artífices indígenas, que conduce al cuestionamiento que se ha hecho sobre la existencia de un conocimiento científico común compartido por estos pueblos.
La computadora en la música
Authors: Galard Jean
Published: November 2016

El uso de la computadora como un instrumento que puede ser capaz de reproducir cualquier tipo de sonido y combinar de manera infinita su variedad en lo que se refiere a timbres, tonos y ritmos, ha creado una nueva relación entre el creador y la música. Las computadoras suelen provocar dos actitudes opuestas entre los compositores: por un lado, entre los entusiastas de la tecnología, se pondera excesivamente la novedad del instrumento y se mitifican sus posibilidades reales; por el otro, entre los escépticos o entre quienes se suelen quedar al margen de las novedades, se produce un exagerado apego a las ideologías humanistas y se llega a una completa aversión por las computadoras. Con un gran conocimiento del ámbito artístico donde se han incorporado los adelantos tecnológicos, Jean Galard analiza de manera muy sintética los diferentes problemas que plantea el uso de la tecnología digital en la producción de la música. Su conclusión es que se ha transformado por completo el vínculo entre el creador y la obra, puesto que ya se ha vuelto menos importante la subjetividad del receptor que la atención al resultado que desencadenan los procesos estocásticos puestos en juego al producir la música con el apoyo de las computadoras.
Biochemical characterization of the nigerian indigenous guinea fowl (Numida meleagris)
Authors: Oguntunji Abel , Ayorinde Kolawole , Aremu Taiwo
Published: November 2016

Blood protein polymorphism has been extensively used for characterization and
estimation of genetic diversity in farm animals. A study on biochemical
characterization and estimation of genetic diversity of Nigerian indigenous
guinea fowls (Numida meleagris) was conducted using four blood proteins
{Haemoglobin (Hb), Carbonic anhydrase (CA), Transferrin (Tf) and Albumin
(Alb)}. Cellulose acetate electrophoresis indicated that all the protein
markers were polymorphic; expressing two co-dominant genes and two genotypes
at their respective locus. Heterozygouse genotypes were prevalent at Hb, Tf
and Alb loci while homozygoutes were more frequent for CA. Allelic
constitution was similar (A and B) for Hb, Tf and Alb while F and S were
typed at CA locus. Gene A had higher frequency of occurrence at Tf and Alb
loci while gene F and B was prevalent at CA and Hb locus, respectively.
Average estimated genetic diversity (heterozygosity) across the genetic
systems was 0.40 and moderate. Prevalence of genes F, A and B at their
respective locus is suggestive of their relevancies to the survival and
adaptability of the studied population to its natural habitat.
Identifying relevant product quality characteristics in the context of very small organizations
Authors: García-Mireles Gabriel
Published: November 2016

Software process improvement models have been developed to support very small
organizations in achieving the software quality expected by their customers.
Software quality, however, allows to be studied from process and product
perspectives. The aim of this work is to attain insights into the extent to
which the product quality view is addressed in very small organizations. A
mapping method was therefore applied in order to identify whether the product
quality characteristics described in ISO/IEC 25010 are included in the
ISO/IEC 29110 basic profile, a process model targeted towards very small
organizations. In addition, an empirical study was conducted to discover the
quality characteristics that practitioners at very small organizations
consider relevant. As a result, it was found that practices in ISO/IEC 29110
are consistent as regards functional correctness quality subcharacteristic,
although practitioners are also considering additional product quality
characteristics.

Published: November 2016

Trading babies or brides for money is widely regarded as morally wrong and sometimes even legally prohibited. Yet here is a puzzle: it seems that parallel exchanges are taking place within the family unit, in the context of custody or reconciliation agreements, both of which might sometimes involve the interweaving of parental or spousal relations with financial exchange. Such cases face much less resentment and criticism, not to mention legal regulation. What can explain this gap in normative treatment? This is the ‘puzzle of intra-familial commodification.’ The article introduces the puzzle, maps it, and evaluates the ways in which it might be resolved. First, it explores the possibility that we might revise our judgment regarding either the permissibility of intra-familial commodification or the wrongfulness of the extra-familial case. Second, it examines why despite the fundamental symmetry between the cases a disparate final judgment might nevertheless be called for. Finally, it explores the option of vindicating the fundamental normative asymmetry. Thinking through the puzzle, the article offers new insights on both the centrality of the market-pricing mechanism for the general problem of commodification and the way familial ties might save intimacy from the corruption of monetary exchange.
De-Ciphering Self-Help
Authors: Sinel Zoë
Published: November 2016

The dominant view of self-help is that it is a remedy exercised by individuals as an alternative to seeking state-sanctioned aid. In other words, self-help consists in ‘legally permissible conduct that individuals undertake absent the compulsion of law and without the assistance of a government official in efforts to prevent or remedy a legal wrong.’ Indeed, self-help is often vaunted as an efficient, or at least potentially efficient, alternative to the slower, costlier, and more cumbersome civil justice system. In our world of increasingly exorbitant legal costs, in which few have meaningful access to the civil justice system, remedies that can be initiated and executed without prohibitive expense merit scholarly attention. Notwithstanding this potential promise, the legal scholarship on self-help is meagre, and, moreover, just what behaviour counts as self-help is left unclear. Self-help, as it is currently understood, risks becoming a meaningless term, a cipher through which almost any behaviour initiated by an individual in furtherance of her legal rights can count as self-help. This article defends a narrower conception of self-help than that recommended by the dominant view. In so doing, it clarifies some of our misgivings about, and checks some of our hopes for, self-help. Self-help, properly understood, is not an alternative to the civil justice system. It is a privilege to act vis-à-vis another in a certain way when certain circumstances exist, and its exercise is always defeasible to a final determination by a court. Self-help, in other words, is not equivalent to taking the law into one’s own hands, as some have implied. This conclusion should comfort those who might worry about the extra-legal nature of self-help and who ask with some trepidation how the unilateral action of one individual can determine the scope and existence of the rights of another. Based on this article’s understanding of self-help, it simply cannot. This conclusion, however, might disappoint those who hope that self-help can be a part of the solution to our current access-to-justice crisis. If it is not a true alternative to the civil justice system, then the specter of costly, inefficient litigation and adjudication remains.
Life-Cycle Benefit–Cost Analysis Framework for Ramp-Metering Deployments
Authors: Chen Xifan , Salem Ossama , Salman Baris
Published: November 2016

The primary objectives of ramp metering are to reduce congestion on freeways by restricting the total flow entering the freeway and to discourage short-distance travelers from using the freeway. Life-cycle cost analysis of ramp-metering deployments has received attention in particular for identifying the strategy with the lowest cost. However, increasing concerns over the effects of congestion on the environment and increasing rates of accidents are urging decision makers to consider the environmental and social effects of ramp-metering deployments in addition to agency costs. This paper presents a high-level benefit–cost analysis framework for ramp-metering deployments. The framework was constructed in consideration of the triple bottom line of sustainability (i.e., economic, environmental, and social factors). More specifically, the framework is made up of four main components: ( a) life-cycle cost analysis, ( b) analysis of benefits achieved through travel time savings, ( c) analysis of benefits achieved through reductions in energy consumption, and ( d) analysis of benefits achieved through reductions in the number of accidents. A hypothetical case study is used to demonstrate the application of the framework. A sensitivity analysis is conducted to determine the effects of higher traffic demand on the benefits achieved. It is expected that the proposed framework can improve the high-level decision-making procedures of transportation agencies in regard to the deployment of ramp meters.
Real-Time Merging Traffic Control at Congested Freeway Off-Ramp Areas

Published: November 2016

This study presents a real-time merging traffic control algorithm to mitigate the problem of freeway congestion resulting from an overspilling off-ramp. The proposed control algorithm aims at maximizing the merge area outflow of the surface street and at the same time preventing the off-ramp queue spillover into the freeway mainstream and the resulting freeway congestion. The potential benefits obtained by applying the proposed control concept are demonstrated by the use of microscopic simulation applied to a real freeway network where recurrent freeway traffic congestion is created as a result of an overspilling off-ramp. The simulation results demonstrated that the proposed control algorithm may improve the prevailing traffic conditions, preventing the formation of freeway congestion and benefiting freeway drivers and surface street users.
Enhancement of cognitive performance in mice and in vitro acetyl-cholinesterase inhibitory activity of 3,3’,4’,5,7-pentahydroxyflavone isolated from Cadaba indica

Cadaba indica, a component of traditional siddha medicine, is used for the therapy of gonorrhea, inflammation, eczema etc. The present study shows that it exhibited acetylcholinesterase inhibitory activity (up to 81.5 ± 1.5%) at the concentration of 3 mg/mL, with the IC50 value of 1.8 mg/mL. Furthermore, the ethanol extract of C. indica therapy at a dose of 100 mg/kg p.o significantly ameliorated the cognitive impaired mice in Y-maze task. The active ingredient was identified as 3,3’,4’,5,7-pentahydroxyflavone. The above results suggest that C. indica would be a potential natural therapeutic remedy for cognitive disorders mediated by cholinergic dysfunction.

Native American Contributions to a Christian Theology of Space
Authors: Baker Josiah
Published: November 2016

Native Christian theologians frequently contribute to a theology of space through their writings on other theological subjects. Native American traditionalism is structured spatially; mythology, rituals and ethics are entirely focused on the tribe's surroundings and the individual's responsibility in living within his or her own place. Thus, Native Christians continue this thought by expressing and exploring the Christian faith through spatial constructs. In discussing the Kingdom of God, they speak of the implications of where the Kingdom resides rather than focusing on when it will be consummated. Additionally, they write on the Christian's responsibility in preserving harmony throughout creation and debate about how this spatial harmony is achieved. In liberation theology, they claim societies can only be liberated by re-establishing their relationship to their surrounding environment; in this way, creation is the basis for liberation. They also discuss the locational implications of eschatology, analysing what it means for every place within the cosmos to be renewed and how Christians should then live within these same places presently. Finally, a brief survey of other issues within theologies of space is presented, and consideration is given to the potential contributions Native Christian theologians could make to these issues as well.
Calculated Effects of Disorder on the Mo Core Levels in Purple Bronze Li2Mo12O34
Authors: Jarlborg Thomas
Published: November 2016

The band structures of ordered and thermally disordered Li 2 Mo 12 O 34 are calculated by use of ab initio density functional theory (DFT)–Linear Muffin-Tin Method (LMTO) with a focus on the behavior of the Mo 3d -core levels. It is shown that thermal disorder and zero-point motion lead to substantial core level broadening, and the broadening at room temperature is predicted to be sufficiently larger than at zero degrees to allow for a detection by X-ray photoelectron spectroscopy (XPS) measurements. However, real purple bronze has 10% Li vacancies, and static disorder will attenuate the T-dependent broadening. It is argued that core level spectroscopies could be a useful tool for the measurement of thermal disorders in many materials, especially for those with minor static disorder. Studies of core levels in magnetic materials will be helpful for an understanding of T-dependent spin moments.
Modeling the Boundaries of Plant Ecotones of Mountain Ecosystems
Authors: Ivanova Yulia , Soukhovolsky Vlad
Published: November 2016

The ecological second-order phase transition model has been used to describe height-dependent changes in the species composition of mountain forest ecosystems. Forest inventory data on the distribution of various tree species in the Sayan Mountains (south Middle Siberia) are in good agreement with the model proposed in this study. The model was used to estimate critical heights for different altitudinal belts of vegetation, determine the boundaries and extents of ecotones between different vegetation belts, and reveal differences in the ecotone boundaries between the north- and south-facing transects. An additional model is proposed to describe ecotone boundary shifts caused by climate change.

Published: November 2016

The detrimental effects of oxidative stress and chronic neuroinflammation on neuronal cell death have been implicated in the pathogenesis of neurodegenerative disorders such as Alzheimer’s disease (AD) and Parkinson’s disease (PD). The nutritional neuroscience is quickly growing, and phytochemicals or phytobioactive compounds such as curcumin, resveratrol, propolis, ginsenoside, and ω-3 polyunsaturated fatty acids (PUFAs) have been extensively applied to potential therapeutic purposes for numerous neurodegenerative diseases for their anti-oxidative and anti-inflammatory effects. However, their administration as food supplements in the daily diet of the elderly is normally a voluntary and less-organized behavior, indicating the uncertainty of therapeutic effects in this sporadic population; specifically, the effective physiological dosages and the real positive effects in preserving brain health have not yet been fully elucidated. In this review, we collect several lines of evidence on these compounds, which constitute a major type of nutraceuticals and are widely integrated into the daily anti-aging caring of elderly patients, and discuss the underlying anti-oxidative and anti-inflammatory mechanisms of these phytochemicals. In conclusion, we highlight the implications of these compounds in the prevention and treatment of geriatric diseases, and of the potential supplementation procedures used as a dietary therapeutic program in clinical nursing services for patients with neurodegenerative diseases or for the elderly in certain communities, which we hope will lead to more beneficial health outcomes with respect to brain function, innate immunity, and gastrointestinal function, as well as more economic and social benefits.
