<p>É imperativa a avaliação de concepções ambientais previamente à proposição de ações de educação ambiental. Neste trabalho, 78 questionários foram preenchidos por interessados em ecoturismo em Armação de Búzios, a respeito de seus conceitos sobre meio ambiente e meio ambiente marinho. Os respondentes apresentaram na maioria 41 a 50 anos, nível superior e renda de 1 a 4 salários mínimos. Aqueles originários da Região dos Lagos apresentaram o conceito integrador com frequência significativamente mais baixa (X<sup>2</sup> = 8,73, <em>p</em> = 0,5%) que os demais. Não foi observada diferença significativa (Qui-quadrado, X<sup>2</sup> = 7,21, <em>p</em> &gt; 10%) para a concepção de meio ambiente entre os sexos. Verificou-se que a maioria dos respondentes (61%) não soube conceituar apropriadamente o ambiente marinho. Não foram observadas diferenças significativas quanto à origem e sexo dos respondentes para este conceito. É urgente a implantação de programas de Informação e Educação Ambiental, direcionados a todos os segmentos sociais locais.</p><p> </p>
A constituição do pensamento ambiental: de Leff a Ingold - bases da visão crítica?

Published: December 2015

<p>O presente artigo busca articular pressupostos teóricos levantados por Tim Ingold a apontamentos de Enrique Leff, com o intento de se configurar uma linha de pensamento ambiental com bases críticas mais integradas. São feitas, tanto por Ingold, quanto por Leff, diversas proposições que rompem as intransigentes visões encasteladas, que fragmentam a questão ambiental, construindo dogmas relacionados a uma visão higienizante, biologizante e reducionista desta, e afastando-a do seu real sentido humanitário, o da crítica social. Os autores recuperam questões preciosas, centrando luz na essencialidade humana, no conceito de ambiente e nas mediações sociais construídas em torno de sua (des)união.</p><p><strong>Palavras-chave: </strong>Pensamento ambiental crítico.

Published: December 2015

<p>Nas últimas décadas a preocupação com o efeito antrópico e seus reflexos sobre o ambiente tem sido intensificada, gerando inúmeros debates em torno dos conceitos de sustentabilidade ambiental e especialmente em relação ao impacto advindo da urbanização, da indústria, da agricultura e da introdução de espécies exóticas no ambiente. Com esse enfoque, este estudo apresenta os resultados obtidos com 151 alunos de ensino fundamental que participaram de uma prática educativa relacionada com as espécies nativas e exóticas e os possíveis prejuízos à biodiversidade das ações do ser humano analisadas sob a perspectiva da CTSA. Os resultados indicaram que uma parcela elevada dos alunos desconhecia os possíveis impactos da agricultura e de forma mais ampla, da introdução de espécies exóticas no ambiente, demandando uma maior atenção a esse aspecto na Educação Ambiental e no Ensino de Ciências.</p><p><strong>Palavras-chave:</strong> Educação Ambiental.

Two Open-Ended, Experiential Learning Cases In Accounting
Authors: Fuglister Jayne , Stegmoyer Matthew , Castrigano Renee 
Published: December 2015

The rapidly changing environment in international business provides an excellent opportunity for instructors to design timely, adaptable, experiential learning, and open-ended cases. This paper presents and discusses how to prepare and use two such cases in the areas of bank accounting and international accounting. The cases can be offered and re-offered until the subjects are no longer relevant or interesting. The structured spreadsheets are easily adapted to other topics for other times and other classes, not just accounting classes. These two cases have been used in online courses as well as traditional courses.
Dodging Dysfunctional Dynamics In Power Exchange
Authors: Boyd David P. 
Published: December 2015

In today’s organizations, the impetus for employee empowerment remains strong. By developing an internal talent base, companies increase the likelihood of comprehensive contributions and also engender loyalty within the ranks. A proclivity for power dispersion is evident among many pundits, with some even decreeing it an ethical mandate. Yet, if rashly executed, empowerment can result in dire outcomes for the individual and dysfunctional consequences for the firm. Through reference to the medium of film, this paper portrays four situations where empowerment efforts have gone awry, accentuating employee estrangement and eroding corporate ethics. Because the behavioral dynamics of film are frozen in time and thus susceptible to recursive scrutiny, students can glean institutional insights that will facilitate career advancement. Just as important, they will confront value conflicts that impel them to clarify their own ethical stance.
Cheating In Business Schools, The Millennial Generation, Gender And Racial Diversity: Has The Paradigm Shifted
Authors: Mathison David L. 
Published: December 2015

Cheating in college is not new. In 1960 over 50 percent of students admitted they cheated. In the second decade of the 21st century has anything changed? This research project looked at three possible new variables, the Millennial Generation, Gender, and Diversity. Results suggest the amount of reported cheating remains the same even with current “Gen Yers” in college. There was also no measured difference in cheating between men and women students. Finally, the present study found that Asian-Americans admitted to cheating far more than the average and Latino-Americans reported to have cheated in college far less than the average current students in college. This paper concludes with the following three implications: 1) Current college undergraduates, “the Millennial Generation,” may actually be more ethical as measured in this study than their Boomer Parents. 2) Women and graduates as measured in this study may be more prone to college cheating than women students in the past—trends of a new post-feminist generation? 3) Finally, diversity and the core values embedded in America’s individual subcultures, such as Asian and Hispanic, appear to significantly influence ethical choices of today’s college students—diversity within the melting pot?
Cucurbitacin B inhibits proliferation, induces G2/M cycle arrest and autophagy without affecting apoptosis but enhances MTT reduction in PC12 cells

Published: December 2015

<p class="Abstract">In the present study, the effect of cucurbitacin B (a natural product with anti-cancer effect) was studied on PC12 cells. It significantly reduced the cell number, changed cell morphology and inhibited colony formation while MTT results showed increased cell viability. Cucurbitacin B treatment increased activity of succinode hydrogenase. No alteration in the integrity of mem-brane, the release of lactic dehydrogenase, the mitochondrial membrane potential, and the expression of apoptotic proteins suggested that cucurbitacin B did not induce apoptosis. The cell cycle was remarkably arrested at G2/M phase. Furthermore, cucurbitacin B induced autophagy as evidence by accumulation of autophagic vacuoles and the increase of LC3II. In addition, cucurbitacin B up-regulated the expression of p-beclin-1, p-ULK1, p-Wee1, p21 and down-regulated p-mTOR, p-p70S6K, CDC25C, CDK1, Cyclin B1. In conclusion, cucurbitacin B inhibited PC12 proliferation but caused MTT pitfall. Cucurbitacin B induced G2/M cell cycle arrest, autophagy, but not the apoptosis in PC12 cells.</p><p> </p>

<p class="Abstract">The methanolic extract of <em>Aegle marmelos</em> leaves was evaluated against cisplatin-induced renal toxicity in rats. Rats were divided into 5 groups: Group 1 received normal saline (1 mL, p.o.) for 15 days; Group II received single dose of cisplatin (5 mg/kg, i.p.) on day 15 and normal saline (1 mL, p.o.) for 15 days; Group III, IV and V were pretreated with extract at doses of 100, 300, 600 mg/kg, p.o., respectively for 15 days followed by single dose of cisplatin on day 15. The blood was collected on the day 16. The urea, creatinine, uric acid, sodium, potassium levels in the serum/blood and TBARS, reduced glutathione (GSH), sueroxide dismutase, catalase in tissue homogenate of kidneys were analyzed. The extract at all doses significantly ameliorated the changes in the serum parameters and decreased the elevated level of TBARS and increased the reduced level of GSH, sueroxide dismutase, catalase. The <em>A. marmelos</em> extract was found to possess nephroprotective and anti-oxidant activities.</p><p> </p>
THE ELLIPTICITY DISTRIBUTION OF AMBIGUOUSLY BLENDED OBJECTS
Authors: Dawson William A. , Schneider Michael D. , Tyson J. Anthony , Jee M. James 
Published: December 2015

ABSTRACT
Using overlapping fields with space-based Hubble Space Telescope and ground-based Subaru Telescope imaging we identify a population of blended galaxies that are blended to such a large degree that they are detected as single objects in the ground-based monochromatic imaging, which we label “ambiguous blends.” For deep imaging data, such as the depth targeted with the Large Synoptic Survey Telescope (LSST), the ambiguous blend population is both large (∼14%) and has a distribution of ellipticities that is different from that of unblended objects in a way that will likely be important for weak lensing measurements. Most notably, for a limiting magnitude of i ∼ 27 we find that ambiguous blending results in a ∼14% increase in shear noise (or an ∼12% decrease in the effective projected number density of lensed galaxies; n
eff) due to (1) larger intrinsic ellipticity dispersion, and (2) a scaling with the galaxy number density N
gal that is shallower than

For the LSST Gold Sample (i < 25.3) there is a ∼7% increase in shear noise (or ∼7% decrease in n
eff). More importantly than these increases in the shear noise, we find that the ellipticity distribution of ambiguous blends has an rms that is 13% larger than that of non-blended galaxies. Given the need of future weak lensing surveys to constrain the ellipticity distribution of galaxies to better than a percent in order to mitigate cosmic shear multiplicative biases, if it is unaccounted for, the different ellipticity distribution of ambiguous blends could be a dominant systematic.
IGR J12580+0134: THE FIRST TIDAL DISRUPTION EVENT WITH AN OFF-BEAM RELATIVISTIC JET
Authors: Lei Wei-Hua , Yuan Qiang , Zhang Bing , Wang Daniel 
Published: December 2015

ABSTRACT
Supermassive black holes (SMBHs) can capture and tidally disrupt stars or substellar objects orbiting nearby. The detections of Sw J1644+57-like events suggest that at least some TDEs can launch a relativistic jet beaming toward Earth. A natural expectation would be the existence of TDEs with a relativistic jet beaming away from Earth. The nearby TDE candidate IGR J12580+0134 provides new insights into the jet phenomenon. Combining several constraints, we find that the event invokes a 8−40 Jupiter mass object tidally disrupted by a

SMBH. Recently, a bright radio transient was discovered by Irwin et al. in association with IGR J12580+0134. We perform detailed modeling of the event based on a numerical jet model previously developed for the radio emission of Sw J1644+57. We find that the radio data of IGR J12580+0134 can be interpreted within an external forward shock model in the Newtonian regime. Using Sw J1644+57 as a template and properly correcting for its luminosity, we argue that the observed X-ray flux in early times is too faint to allow an on-beam relativistic jet unless the Lorentz factor is very small. Rather, the X-ray emission is likely from the disk or corona near the black hole. From various constraints, we find that the data are consistent with an off-beam relativistic jet with a viewing angle of

and an initial Lorentz factor of

a few. This scenario can readily be tested in the upcoming very long baseline interferometry observations.
Role of CrkII Signaling in RANKL-Induced Osteoclast Differentiation and Function

Published: December 2015

Abstract
Rac1, a member of small GTPases, is a key regulator of osteoclast differentiation and function. The Crk family adaptor proteins, consisting of Src homology (SH) 2 and SH3 protein-binding domains, regulate cell proliferation, migration, and invasion through Rac1 activation. In this study, we examined the role of CrkII in osteoclast differentiation and function. Retroviral overexpression of CrkII in osteoclast precursors enhanced osteoclast differentiation and resorptive function through Rac1 activation. The knockdown of CrkII in osteoclast precursors using small interfering RNA inhibited osteoclast differentiation and its resorption activity. Unlike wild-type CrkII, overexpression of the three SH domains in mutant forms of CrkII did not enhance either osteoclast differentiation or function. Phosphorylation of p130 Crk-associated substrate (p130Cas) by osteoclastogenic cytokines in preosteoclasts increased the interaction between p130Cas and CrkII, which is known to be involved in Rac1 activation. Furthermore, transgenic mice overexpressing CrkII under control of a tartrate-resistant acid phosphatase promoter exhibited a low bone mass phenotype, associated with increased resorptive function of osteoclasts in vivo. Taken together, our data suggest that the p130Cas/CrkII/Rac1 signaling pathway plays an important role in osteoclast differentiation and function, both in vitro and in vivo.
El diseño periodístico como actor fundamental en los modelos de prensa popular. Una aproximación a las causas del cierre del diario Claro
Authors: González Diez Laura , Puebla Martínez Belén , Birkner Thomas , Pérez Cuadrado Pedro 
Published: December 2015

Este trabajo pretende demostrar la importancia del diseño periodístico a la hora de establecer una clasificación de los diarios impresos y de su vertiente popular/sensacionalista, donde los elementos formales cobran un protagonismo fundamental. Se pretende acotar uno de los escasos intentos de consolidar en España un diario importante de información sensacionalista. En 1991, una extraña alianza de editores alemanes (Axel Springer) y españoles (Prensa Española, editora de Abc) pone en circulación el diario Claro, con la idea de conseguir un producto de difusión masiva. Metodología: Se plantea un trabajo de campo basado en el análisis de los elementos gráficos y tipográficos que –con una muestra íntegra de todos los ejemplares publicados– definen la estructura de la portada de un diario de esta índole y alertan del protagonismo de los recursos visuales implícitos a este modelo de prensa. Resultados y conclusiones: Claro se inscribe de lleno en los modelos de prensa sensacionalista de corte europeo, no sólo por el tipo de información que se ofrece sino, sobre todo, por la estructura y soporte que maneja y que lo convierten en ejemplo representativo del ámbito de la prensa popular más pura.
Effect of feed restriction and different crude protein sources on the performance, health status and carcass traits of growing rabbits
Authors: Uhlířová L. , Volek Z. , Marounek M. , Tůmová E. 
Published: December 2015

<p>We evaluate the effect of the crude protein source (CP) in combination with 2 feeding strategies (AL: ad libitum or R: restricted) on the performance, health status and carcass traits of growing-fattening rabbits (between 33 and 75 d of age). Two experimental diets were formulated; the first containing soybean meal (SBM: 70 g/kg) as the main CP source and the second containing white lupin seeds (WLS: 105 g/kg) as the main CP source. A total of 160 weaned Hyplus rabbits (774±10 g live weight) were randomly allocated to the experimental groups, combination of feeding strategy and diet (AL SBM, R SBM, AL WLS and R WLS; 40 rabbits per group with 4 rabbits per cage), for 42 d. The feeding programme was applied as follows: both the AL SBM and AL WLS rabbits were fed ad libitum for the entire fattening period, whereas the R SBM and R WLS rabbits were subjected to feed restriction between 33 and 47 d of age (75% of the ad libitum intake). Afterwards, all restricted rabbits were fed ad libitum until 75 d of age. Regardless of the CP source, the feed restriction reduced the final live weight by 83 g, chilled carcass weight by 65 g, and dressing out percentage by 0.9 percentage points (P&lt;0.05). There was a higher chilled carcass weight (+114 g; P=0.001) and reference carcass weight (+91 g; P=0.001) in rabbits fed with WLS diet than in rabbits fed with SBM diet. No dead or morbid rabbits were observed in restricted rabbits during the restriction period. There was no effect of the diet on the health of rabbits. However when the rabbits of AL SBM and AL WLS group were compared did we observe a lower number of rabbits at sanitary risk in AL WLS group (2 vs. 12 rabbits, P=0.006). In conclusion, the growth performance was not affected by the crude protein source, and no interaction between dietary CP source and feeding regime was observed. Feed restriction regime did not improve sanitary risk index throughout the entire period.</p>
Composite Resin Stamping Technique using a Translucent Hot Melt Adhesive
Authors: Dimashkieh Reda Mohiddin 
Published: December 2015

ABSTRACT
Restoring a complex occlusal morphology of the posterior teeth is tremendously difficult when direct composite resin restorative materials are used because carving of the solid polymerized mass is accomplished mechanically using rotary instruments. The preoperative occlusal morphology of the tooth provides for the preparation of an ideal index of the esthetic and functional anatomy in cases where the carious lesion is confined within a shell of undermined yet intact enamel, and is registered using a transparent hot melt adhesive (HMA) material. The registration is then used as an index to reproduce the occlusal morphology in the final incremental restorative layer during the composite resin restoration, which also allows for the photopolymerization of the restoration through the translucent index.

The Relationship between Palatal Displacement of Upper Canines and Incisors Widths in a Syrian Sample of Patients with Uncrowded Arches
Authors: Mahaini Luai 
Published: December 2015

ABSTRACT
The aim of this study investigates mesiodistal crown size of the maxillary and mandibular incisors of patients with palatally impacted canines (PDC). Pretreatment dental casts of orthodontic patients with PDC of one or both maxillary canines (N: 33) were collected. This PDC sample was matched according to age and sex with pretreatment dental casts from unaffected orthodontic patients. For the PDC and matched control samples, maximum mesiodistal crown diameters were recorded for the four incisors on the right side only. The results showed that, on average, the mesiodistal crown diameters for the maxillary and mandibular incisors measured smaller in the PDC sample than in the control sample. These findings of statistically significant tooth-size reductions associated with PDC occurrence indicate a generalized pattern of reduced tooth size as a characteristic associated with the PDC anomaly. Further, the presence of generalized tooth-size reduction in cases with palatally displaced canines help explain why most orthodontic treatment plans for PDC patients are of the nonextraction type.

Simulating spatial and temporal varying CO2 signals from sources at the seafloor to help designing risk‐based monitoring programs
Authors: Ali Alfatih , Frøysa Håvard G. , Avlesen Helge , Alendal Guttorm 
Published: December 2015

AbstractRisk‐based monitoring requires quantification of the probability of the design to detect the potentially adverse events. A component in designing the monitoring program will be to predict the varying signal caused by an event, here detection of a gas seep through the seafloor from an unknown location. The Bergen Ocean Model (BOM) is used to simulate dispersion of CO2 leaking from different locations in the North Sea, focusing on temporal and spatial variability of the CO2 concentration. It is shown that the statistical footprint depends on seep location and that this will have to be accounted for in designing a network of sensors with highest probability of detecting a seep. As a consequence, heterogeneous probabilistic predictions of CO2 footprints should be available to subsea geological CO2 storage projects in order to meet regulations.
