Arte Pública como imagem da Cidade: seus trânsitos e apropiações
Authors: Malheiros Ubiraélcio 
Published: May 2016

Resumo Esse artigo tem como objetivo abordar a arte pública como imagem da cidade e meio de representação urbana. A ideia é mostrar e analisar intervencões urbanas em espaços e monumentos tradicionais de Belém do Pará – Brasil, que representem a história e a vida da cidade em seus trânsitos e apropriacões, de maneira à resignificar espaços e lugares que sejam imagens coletivas dos habitantes dessa cidade. Assim sendo, “Arte pública como imagem da cidade: seus trânsitos e apropriações” relaciona-se a um panorama da arte contemporânea de Belém, ou seja, da arte urbana (aqui entendida como arte pública efêmera) e de suas manifestações, na última década, que se relacionam e se imbricam com os monumentos tradicionais (arte pública permanente). Todo o trabalho está fundamentado na obra de três artistas paraenses: Berna Reale, Victor de La Rocque e Murilo Rodrigues, que têm como linguagem artísticas intervenções que acontecem em diferentes lugares e monumentos da cidade porque sua tradição é significativa para construcão da imagem urbana e para seus fluxos. É importante lembrar que esses trabalhos são efêmeros – enquanto performances que se desdobram em videos e fotografias – e participaram em diferentes versões do Arte Pará (Importante Salão de Arte Contemporânea paraense). Abstract Absract: This article aims to present public art as a city’s image and as an urban representation medium. The idea is to present and analyze urban interventions on monuments and spaces that are traditional in Belém do Pará – Brazil, which represent the city’s history and life through its movements and appropriations in a way to bring new meaning to spaces and places that form the collective image of the city’s inhabitants. Therefore, “Public Art as a city’s image: it’s shifts and appropriations” relate to a contemporary art landscape in Belém, in other words, the urban art (understood here as public and ephemeral art) and it’s manifestations on the last decade that relate and add to the traditional monuments (public and permanent art). All the work is based on the work of three artist from Para?: Berna Reale, Victor de La Rocque e Murilo Rodrigues, which have as artistic language interventions that happen in different places and monuments in the city, because their tradition is of significance for the urban image construction and its fluxes. It is important to remember that these works of art are ephemeral – performances that unfold in video and photographs – and that have parti- cipated in different versions of Arte Pará (important exhibition of Pará’s contemporary art).

Authors: Zamani Gerannaz , Ebadi Saman 
Published: May 2016

The structure of the conclusion sections in Research Articles (RAs) is of significance in academic writing. The conclusion section does not only provide an outline of the study, but also other important elements, such as recommendations, implications and statements of possible lines of future research. This paper reports on an analysis of the conclusion sections of Persian and English Research Articles (RAs) published in international journals. To meet this end 20 RAs were selected from the fields of Civil Engineering and Applied Linguistics. The Conclusion sections of the papers were examined for their moves based on Yang and Allison’s (2003) move model. The frequency analysis of the moves showed slight differences among the moves employed and the Chi-Square analysis did not show significant differences between the moves used in Conclusion sections of RAs in Civil Engineering and Applied Linguistics as well as between Persian and English RAs. The study contributes to a richer understanding of the conclusion structure of research articles and offers ESP/EFL instructors and researchers, insights which can be used in the instruction of the conventions or expectations of academic writing. Novice writers and non-native students can benefit from it, mainly because it helps them eliminate their writing dilemmas and assists them to take part in international discourse communities. Key Words: Conclusion section; Contrastive move analysis; Genre analysis; Research articles
Teaching and learning cinema and visual languages through economics-business studies and law in high school: An experimental interdisciplinary approach
Authors: Poli Anna 
Published: May 2016

In Italy, little is being done to promote cinema studies and the ability to analyse films and/or multimedia works among high school students. Although Italian legislation provides guidelines on specific learning objectives, activities and content to be included in high school courses, film and media language is still not encouraged in schools. The pilot introduction of cinema at the C. Tenca High School in Milan had the aim of demonstrating the value of film as an educational and epistemological resource and fostering the development of innovative interdisciplinary teaching strategies. Themes related to cinematographic language, Economics-Business Studies and law were introduced and analysed via the exploration of early films (late 1800s and early 1900s). The students investigated the topics of advertising, building a brand name, online marketing and the role of the media in shaping public opinion. In order to enhance studentsâ€™ skills in analysing interactive communications, we introduced the themes of data journalism and fact-checking. The results are discussed in terms of a possible role for Cinema in the study of Economics-Business Studies and Law and of how cinema might become an interdisciplinary resource for other school subjects.

Background: Atorvastatin (ATV) has shown pleiotropic effects on bone tissue, and osteoporosis can aggravate periodontitis. Thus, the effects of ATV on experimental periodontitis (EP) in rats subjected to glucocorticoid‐induced osteoporosis (GIOP) was assessed.Methods: Male Wistar rats were divided into the following groups: 1) naive; 2) EP; 3) GIOP + EP; and 4) ATV. Groups GIOP + EP and ATV received 7 mg/kg dexamethasone intramuscularly once per week for 5 weeks, and the others received saline (SAL). Groups EP, GIOP + EP, and ATV were submitted to EP by ligature around the maxillary left second molars for 11 days. Group ATV received 27 mg/kg ATV orally, and the others received SAL 30 minutes before EP. Periodontium was analyzed by macroscopy, microtomography, and histopathology; by immunohistochemical examination of receptor activator of nuclear factor‐κB ligand (RANKL), osteoprotegerin (OPG), wingless (WNT) 10b, dickkopf‐related protein 1 (DKK‐1), and β‐catenin; and by enzyme‐linked immunosorbent assay analysis of myeloperoxidase (MPO), tumor necrosis factor (TNF)‐α, interleukin (IL)‐1β, IL‐6, IL‐8, IL10, reduced glutathione (GSH), superoxide dismutase (SOD), and catalase (CAT). Leukogram, liver and kidney enzymes, and bone‐specific alkaline phosphatase (BALP) serum levels were evaluated.Results: ATV decreased bone loss, reduced MPO, TNF‐α, IL‐1β, IL‐6, and IL‐8, and increased IL‐10, GSH, SOD, and CAT levels. ATV reduced RANKL and DKK‐1 and increased OPG, WNT10b, and β‐catenin expressions and BALP activity.Conclusion: ATV reduced inflammation, oxidative stress, and bone loss in rats with EP and GIOP, with participation of the WNT signaling pathway.
Las canoas de jade del sur de Veracruz como elemento iconográfico olmeca previo a la odisea del Dios del maíz maya
Authors: Uch Avendano Eric Orlando 
Published: May 2016

En el artículo se revisan algunas canoas de jade olmecas procedentes del sur de Veracruz, pertenecientes a museos y colecciones privadas de México y el extranjero. El argumento principal señala que estas canoas constituyen una representación de un complejo de ideas relacionadas con un viejo mito de creación olmeca, que involucra a una deidad relacionada con el maíz. Para reforzar esta interpretación, se revisan lecturas hechas por epigrafistas de artefactos mayas del Clásico, en los cuales se recuperan relatos de la creación llevada a cabo por el joven Dios del Maíz, que induye un pasaje donde se utiliza una canoa como transporte. Este contexto de representaciones sirve como base para señalar una posible continuidad entre ideologías del mundo olmeca y el maya, y para ofrecer una interpretación de un signo grabado en una canoa de jade de Campeche.
Diversity pattern of habitats of Macrophytes in Keibul Lamjao National Park (KLNP), a floating mat (Phumdi) environment of Loktak Lake, Manipur, India
Authors: Haripriya Devi Maibam , Kumar Singh Potsangbam 
Published: May 2016

Keibul Lamjao National Park (KLNP), Loktak lake Manipur, north-east India which is one of the 25 Ramsar sites of international importance and the biggest fresh water Lake in India. Macrophytes of the floating Phumdi mat environment of KLNP play an important role in the aquatic environment. An investigation was planned during the period of about three years from March, 2010 to December 2012, to study the diversity pattern of habitats of macrophytes available in six study sites of KLNP viz., 1.Kumbi, 2.Khordak, 3.Keibul, 4.Toya, 5. Nongmaikhong and 6. Sargam. All total 85 dominant plant species were recorded. Maximum plant species (49) was observed in Site-1 Kumbi (Altitude-780m) and minimum (27) in Site-3 Keibul (Altitude-772). The variation of plant species may be because of the slight variation of altitude. As the six study sites are distributed as floating aquatic environment in KLNP Loktak Lake, there is favourable place of the plants in higher altitude and altitude represents a complex gradient along which many environmental variables change concomitantly. In all the six study sites, common distribution of ten dominant plant macrophytes viz., Ageratum conizoides, Hedychium coronarium, Leersia hexandra, Oenanthe javanica, Phragmites karka, Polygonum sagittatum, Saccharum munja, Thelypteris interrupta and Zizania latifolia was noticed. Individual dominant plant was recorded in other sites also viz., Azola piñata in site-6; Xanthium atrumarium, Polygonum orientale, Dichrocephala latifolia and Cymbopogon citratus in site-2; Arundo plinii, Cuscuta reflexa, Gnaphalium luteo-album, Hydrilla verticillata, Marsilia minuta, Saccolepis interrupta, Selvenia cuculata and Utricularia spp. in site-1. Variation of IVI value of dominant plant species was observed in this study. Even though 85 dominant plants were selected for all the 6 sites, however, maximum plant richness expressed in IVI was recorded in case of Zizania latifolia (Site-5, IVI-87.5) and minimum IVI in case of Xanthium strumarium (Site-2, IVI-1.13). The diversity pattern and habitats of macrophytes in KLNP Phumdi environment might be due to water availability along the altitudinal gradient and other environmental factors suited in the study sites and expected to be an important factor affecting the survival and fecundity of plant population. We need to conserve the natural habitat of KLNP thereby maintaining the luxuriant growth of the seasonal and perennial, macrophytes, so as to maintain the natural flora and fauna of the park. These plants are the food of man and animal therefore, it needs a proper care and attention to protect them from over exploitation. Considering the diversity pattern of habitats of Macrophytes in KLNP, a floating mat Phumdi environment with high floral diversity and unique vegetation assemblage, it has been suggested that this track and adjoining sites should be declared as ecologically sensitive area not only the World Heritage Site.

Authors: Bradshaw Noel-Ann , Richardson Karen 
Published: May 2016

This case-study shows how successful collaboration between colleagues from the University of Greenwich library and Mathematical Sciences department has resulted in increased library usage and an improvement in important employability skills for mathematics students. It is argued that similar collaborations in other STEM disciplines within the University could have an equally beneficial effect.
Developing an Educational Game to support Cognitive Learning
Authors: Kiernan Mary , Kazimoglu Cagin , Bacon Liz , Mackinnon Lachlan 
Published: May 2016

This paper outlines how an educational game can be used to support the learning of programming within the Computer Science (CS) discipline and reports on the qualitative results of a series of rigorous studies conducted through using this game on first year introductory programming students. Although this paper applies to the CS discipline computational thinking (CT) is an intrinsic part of the games process applicable to any discipline. This is because CT is a problem solving approach which combines logical thinking with CS concepts to produce a recipe for solving problems in any discipline regardless of where the problem lies.
More than one way to flip a class: learning analytics for mixed models of learning
Authors: Dix Alan 
Published: May 2016

This case study presents personal experiences in the reuse of materials, originally prepared for a small-scale MOOC, in face-to-face flipped classroom and blended learning teaching. While some of the literature on the flipped classroom suggests a quite uniform pedagogic style for each class, albeit differing between advocates, the experience of the author was far more pedagogically diverse depending on the type of material and workload of the students. Fine-grain learning analytics were also critical; these both allowed targeted feedback (enhancing student learning) and gave a sense of control (enhancing academic motivation and well being).
Can We Manage Nonpoint‐Source Pollution Using Nutrient Concentrations during Seasonal Baseflow?
Authors: McCarty James A. , Haggard Brian E. 
Published: May 2016

Core Ideas
Nutrient concentrations in streams are positively correlated during baseflow and runoff conditions.
High nutrient concentrations at baseflow suggest high nutrient loads from nonpoint sources.
Manage nonpoint sources by targeting subwatersheds with elevated nutrient concentrations during baseflow.
Focusing on baseflow conditions frees up resources to monitor water quality more broadly across watersheds.
Nationwide, a substantial amount of resources has been targeted toward improving water quality, particularly focused on nonpoint‐source pollution. This study was conducted to evaluate the relationship between nutrient concentrations observed during baseflow and runoff conditions from 56 sites across five watersheds in Arkansas. Baseflow and stormflow concentrations for each site were summarized using geometric mean and then evaluated for directional association. A significant, positive correlation was found for NO3–N, total N, soluble reactive P, and total P, indicating that sites with high baseflow concentrations also had elevated runoff concentrations. Those landscape factors that influence nutrient concentrations in streams also likely result in increased runoff, suggesting that high baseflow concentrations may reflect elevated loads from the watershed. The results highlight that it may be possible to collect water‐quality data during baseflow to help define where to target nonpoint‐source pollution best management practices within a watershed.
An Integrated Landscape Designed for Commodity and Bioenergy Crops for a Tile‐Drained Agricultural Watershed
Authors: Ssegane Herbert , Negri M. Cristina 
Published: May 2016

Locating bioenergy crops on strategically selected subfield areas of marginal interest for commodity agriculture can increase environmental sustainability. Location and choice of bioenergy crops should improve environmental benefits with minimal disruption of current food production systems. We identified subfield soils of a tile‐drained agricultural watershed as marginal if they had areas of low crop productivity index (CPI), were susceptible to nitrate‐nitrogen (NO3–N) leaching, or were susceptible to at least two other forms of environmental degradation (marginal areas). In the test watershed (Indian Creek watershed, IL) with annual precipitation of 852 mm, 3% of soils were CPI areas and 22% were marginal areas. The Soil and Water Assessment Tool was used to forecast the impact of growing switchgrass (Panicum virgatum L.), willow (Salix spp.), and big bluestem (Andropogon gerardi Vitman) in these subfield areas on annual grain yields, NO3–N and sediment exports, and water yield. Simulated conversion of CPI areas from current land use to bioenergy crops had no significant (p ≤ 0.05) impact on grain production and reduced NO3–N and sediment exports by 5.0 to 6.0% and 3.0%, respectively. Conversion of marginal areas from current land use to switchgrass forecasted the production of 34,000 t of biomass and reductions in NO3–N (26.0%) and sediment (33.0%) exports. Alternatively, conversion of marginal areas from current land use to willow forecasted similar reductions as switchgrass for sediment but significantly (p ≤ 0.01) lower reductions in annual NO3–N export (18.0 vs. 26.0%).Core Ideas
We classified subproductive soils or soils vulnerable to environmental degradation as marginal.
We forecasted the biomass potential of soils and associated water quality benefits.
Conversion of soils of lowest CPI to energy crops had no impact on NO3–N export.
Targeted conversion of 22% of the watershed to energy crops reduced nutrient export.
Largest environmental benefits were from converting environmentally vulnerable land.
Influence of Organic Amendment and Compaction on Nutrient Dynamics in a Saturated Saline‐Sodic Soil from the Riparian Zone
Authors: Miller J. J. , Bremer E. , Curtis T. 
Published: May 2016

Cattle grazing in wet riparian pastures may influence nutrient dynamics due to nutrient deposition in feces and urine, soil compaction, and vegetation loss. We conducted a lab incubation study with a saline‐sodic riparian soil to study nutrient (N, P, S, Fe, Mn, Cu, and Zn) dynamics in soil pore water using Plant Root Simulator (PRS) probes and release of nutrients into the overlying ponded water during flooding. The treatment factors were organic amendment (manure, roots, and unamended control), compaction (compacted, uncompacted), and burial time (3, 7, and 14 d). Amendment treatment had the greatest impact on nutrient dynamics, followed by burial time, whereas compaction had little impact. The findings generally supported our hypothesis that organic amendments should first increase nitrate loss, then increase Mn mobility, then Fe mobility and associated release of P, and finally increase sulfate loss. Declines in nitrate due to amendment addition were small because nitrate was at low levels in all treatments due to high denitrification potential instead of being released to soil pore water or overlying water. Addition of organic amendment strongly increased Mn and Fe concentrations in overlying water and of adsorbed Fe on PRS probes but only increased Mn on PRS probes on Day 3 due to subsequent displacement from ion exchange membranes. Transport of P to overlying water was increased by organic amendment addition but less so for manure than roots despite higher P on PRS probes. The findings showed that saline‐sodic soils in riparian zones are generally a nutrient source for P and are a nutrient sink for N as measured using PRS probes after 3 to 7 d of flooding.Core Ideas
Saline‐sodic soils in riparian zones are generally a source for P and a sink for N.
PRS probes provided a cost‐effective and simple method to monitor nutrient mobility.
Organic amendment influenced nitrate, P, Mn, Fe, Cu, and Zn nutrient dynamics.

Greenhouse gas (GHG) emission measurements from livestock excreta in Africa are limited. We measured CH4 and N2O emissions from excreta of six Boran (Bos indicus) and six Friesian (Bos taurus) steers near Nairobi, Kenya. The steers were fed one of three diets (T1 [chaffed wheat straw], T2 [T1 + Calliandra calothyrsus Meissner – 0.2% live weight per day], and T3 [T1 + calliandra – 0.4% live weight every 2 d]). The T1 diet is similar in quality to typical diets in the region. Calliandra is a leguminous fodder tree promoted as a feed supplement. Fresh feces and urine were applied to grasslands and emissions measured using static chambers. Cumulative 28‐d fecal emissions were 302 ± 52.4 and 95 ± 13.8 mg CH4–C kg−1 dry matter for Friesen and Boran steers, respectively, and 11.5 ± 4.26 and 24.7 ± 8.32 mg N2O–N kg−1 dry matter for Friesian and Boran steers, respectively. For urine from Friesian steers, the N2O emissions were 2.8 ± 0.64 mg N2O–N 100 mL urine−1. The CH4 emission factors (EFs) (246 ± 49.5 and 87 ± 12.7 g CH4–C yr−1 animal−1 for Friesan and Boran, respectively) were lower than the International Panel on Climate Change EFs (750 g CH4–C animal−1 yr−1), whereas the N2O EFs (0.1 and 0.2% for the Friesian and Boran feces, respectively, and 1.2% for urine) were also lower than International Panel on Climate Change estimates. The low N content of the excreta likely caused the low emissions and indicates that current models probably overestimate CH4 and N2O emissions from African livestock manure.Core Ideas
GHG emissions from African livestock excreta is lower than IPCC tier 1 emission factors.
Low‐quality feeds with low protein content result in low N content of excreta.
Supplementation of cattle diet with calliandra reduced the methane emissions from cattle feces.
The species of cattle causes differences in GHG emissions from feces.
