Assessing Student Success in a Project-Based Learning Biology Course at a Community College
Authors: Berchiolli Barbara , Movahedzadeh Farahnaz , Cherif Abour
Published: December 2017

Project-based learning (PBL) and traditional teaching methods represent two opposing pedagogical philosophies. A PBL Biology lab course was designed and taught concurrently with its traditional counterpart to compare student success. The PBL course investigated the effects of simulated acid rain on the rate of adaptation in two species that differ in complexity and rate of reproduction, Caenorhabditis elegans and Paramecium caudatum. The species with the highest number of survivors at the end of six week's exposure to acid rain was deemed to have adapted best. In two out of three semesters students concluded that P. caudatum responded to acid rain with the greatest rate of adaptation. Student success was compared between both types of courses using four methods of assessment: student academic performance, retention rate, transfer rate to four-year institutions, and participation points. The results of two methods of assessment out of four were statistically significantly higher in the PBL courses. Considering that the other two methods of assessment did not favor traditional pedagogy, but produced comparable student success in the traditional and PBL courses, it can be concluded that PBL pedagogy is a highly desirable alternative to traditional teaching methods in biology courses at the community college level.
Transsphenoidal surgery for pituitary tumours: frequency and predictors of delayed hyponatraemia and their relationship to early readmission
Authors: Krogh Jesper , Kistorp Caroline N , Jafar-Mohammadi Bahram , Pal Aparna , Cudlip Simon , Grossman Ashley
Published: December 2017

Objective

A major cause of readmission after transsphenoidal surgery (TSS) is delayed hyponatraemia. The purpose of this study was to identify predictors of hyponatraemia one week post surgery and predictors of 30-day readmissions for hyponatraemia.

Design

A retrospective cohort study including patients who had TSS performed for pituitary lesions.

Method

The risk of readmission for hyponatraemia was assessed in consecutive patients between January 2008 and March 2016. The risk of hyponatraemia one week post surgery was assessed in patients admitted for TSS between July 2011 and March 2016.

Results

Of all included patients, 56/522 (10.7%) were readmitted within 30 days. Hyponatraemia was found in 14/56 (25%) of 30-day readmissions. We did not identify any predictive variable for hyponatraemia on readmission. The number of patients with hyponatraemia on the seventh post-operative day was 26/314 (8.3%). The risk of hyponatraemia one week post surgery was increased by an odds ratio of 2.40 (95% CI: 1.06–5.40) in patients with a tumour abutting the optic chiasm and by an odds ratio of 1.16 (1.04–1.31) per mmol/L decrease in sodium levels on the first post-operative day.

Conclusions

Hyponatraemia occurred in 25% of readmissions; however, we did not identify any predictive variable for readmission with hyponatraemia. One week post surgery, 8.9% had hyponatraemia. Tumours pressing on the optic chiasm as well as a fall in sodium levels on the first post-operative day were associated with an increased risk of hyponatraemia one week post surgery. We suggest that a day 7 serum sodium <130 nmol/L should lead to concern and the provision of patient advice.

This paper studies the devices that university students in teacher education incorporate into their personal learning environments (PLE). It also examines the time that students dedicate to activities related to ICT, the factors that encourage or frustrate the incorporation of tools to students’ PLE, and the characteristics that this population desires for a PLE. For this, a questionnaire has been applied using Likert scales in a sample of 668 students divided into 15 groups, enrolled in the Elementary Education Bachelor’s degree program, at the University of Granada, Spain. The data were analyzed using descriptive and inferential statistics (with 95% confidence interval). Also, correlation tests (Kendall coefficient τ) and analysis of variance (test of Kruskal-Wallis H) were employed. The results showed that laptops and smartphones are the most accessible devices for students. The findings also showed that students spend little time to visiting university platforms, they prefer PLE tools to be productive and to allow them to connect with others, and they want PLE to be interactive, customizable and useful.

Published: December 2017

This paper presents an analysis on the satisfaction of night school students about their educational process, from the valuation they have of their own motivation, physical infrastructure facilities, and interpersonal relationships between students and teachers, specifically in the technical and professional education fields. All this aimed to analyze components that increase the feeling of well-being, and enhance the promotion and academic success based on criteria to prevent the school dropout. To do so, we conducted a factor analysis with information obtained from a questionnaire based on a Likert scale. The questionnaire was applied to a sample of 120 participants; with it, we identified some important indicators to be considered in actions to prevent dropout in adult students. The collected information was presented in statistical tables, which display indicators of satisfaction about infrastructure, teacher´s treatment, and student´s motivation.

Authors: Rui-Hong Liu  , Fa-Tang Li
Published: December 2017

Nano-ZnFe2O4 photocatalysts are one-step synthesized via solution combustion route, which are characterized by XRD, TEM, and UV-vis DRS. The photocatalytic activity of these samples are evaluated by the removal of thiophene in model oil under visible light irradiation. The influences of fuel amount on the particle size and photocatalytic performance of the as-synthesized catalysts are investigated. The results show that the ZnFe2O4 with the particle size of 21.9 nm exhibits the highest photocatalytic ability, which is acquired using triethylamine hydrochloride as fuel in the fuel-rich combustion condition. The desulfurization yield of model oil can reach 92.5% in 5 h photo-irradiation and the sulfur content can be decreased from 200 ppm to 15 ppm.

Hasil penelitian menunjukkan bahwa pertumbuhan ikan nila BEST tidak berbeda nyata antara pakan uji hasil formulasi dengan pakan komersil (P>0,05). Nilai FCR pakan komersil tidak berbeda nyata dibandingkan pakan formulasi. Berdasarkan hasil tersebut, keuntungan dengan menggunakan bahan baku lokal lebih tinggi dibandingkan dengan pakan komersil.The purpose of this study was to compare the utilization effects of locally found feed ingredients in Klungkung, Bali for BEST strain tilapia feed compared to a commercial feed. The selection of local raw ingredients used in the feed formulation was based on the best nutrient composition for tilapia needs and its price determined through a separate survey. Formulated test feed contained 29%-30% protein. The formulated feed performance was compared to the commercial feed using the T-test. After acclimatization, the fish (BEST strain tilapia, total length of 5.7 ± 0.4 cm; weight of 3.1 ± 18 g) were randomly stocked into six hapas, each measuring 2 m × 1 m × 1 m in size placed inside a pond (100 m2) with a density of 65 fish/m3 and fed 3% of the total fish biomass per day for three months rearing period. The results showed that the growth of BEST tilapia was not significantly different between the formulated feed and commercial feed (P>0.05). The FCR value of the commercial feed was not significantly different compared to the formulation feed. Based on these results, the benefit of using local raw materials was higher than that of commercial feed.

The Influence of Abattoir Wastes on Macroinvertebrate Distribution in River Idemili, Obosi, South-Eastern Nigeria
Authors: IBEMENUGA Keziah N. , NDUBA Blessing C. , EYO Joseph E.
Published: December 2017

The influence of abattoir wastes on macroinvertebrates distribution in River Idemili, South-Eastern Nigeria, was studied. Three sampling stations 1, 2 and 3 representing upstream of the impacted site, impacted site and downstream of the impacted site respectively were selected. The water quality characteristics, which were significantly different (p<0.05) among the study stations, include water temperature, conductivity, dissolved oxygen and biochemical oxygen demand and phosphatephosphorus. There was no significant difference (p>0.05) in the levels of pH and nitrate-nitrogen among the study stations. Thirteen taxa composed of 201 individuals were encountered. Station 1 had the highest taxa (13) species, as well as the number of individuals (92, 45.8%), followed by station 3 with 12 species and 64 (31.8%) individuals. Station 2 had the least diversity and abundance of 6 species composed of 45 (22.4%) individuals. Macroinvertebrate abundance in the study stations were significantly different (p<0.05). Arthropoda (54.7%) was the dominant phylum. Chironomids (Family: Chironomidae) dominated the samples at all the study stations. Coleoptera was completely absent at the impacted site due to organic pollution. Margalef’s species richness and Shannon Wiener index for general diversity were the highest in stations 1 and 3. The low macroinvertebrate abundance, species richness and Shannon diversity index in station 2 may be attributed to the decimating impacts of abattoir wastes entering the water in this station. Renkonen’s number calculated for pairs of stations revealed that stations 1 and 3 were significantly similar, while stations 1 and 2, 2 and 3 were dissimilar. Conclusively, abattoir wastes distort water quality and affect the community structure, composition, distribution and abundance of macroinvertebrates inhabiting aquatic ecosystems.

Published: December 2017

The conservation status of Vitellaria paradoxa in Kwara state was studied. The frequency ranged from 20% at Offa and Ilofa to100% at Jebba and Kaiama, as the shea tree occurred twice in the ten sampling points at Offa and Ilofa, but occurred in all sampled sites at Jebba and Kaiama. The highest tree mean density of 34 trees/ha was noted at Kaiama and the lowest at Offa 4 trees/ha. The overall mean densities of the species was 13.33 trees/ha. These show that Vitellaria paradoxa trees were more conserved towards the Northern part of the state than the Southern part. The majority of the trees were between (21-30 cm) diameter class, which indicated that they were saplings and very few were around (<10 cm) diameter class. The results showed low population of seedlings in the state, especially at the Northern part of the state. This might be due to trees’ removal for farming activities, uncontrolled incessant bush burning and trampling by grazing live stocks in the areas.

Published: December 2017

Zilla spinosa is one of the dominated woody perennial shrubs widespread in the Egyptian Red sea coastal desert, belonging to family Brassicacea. Z. spinosa is used as a folk medicine and for heating by local people. Z. spinosa inhabits arid habitats exposed to adverse climatic changes which influence the production of the bioactive natural products. The natural secondary products have significant importance for plant acclimatization to the arid habitats beside their significant practical application in medicinal, nutritive and industrial purposes. The accumulation levels of some natural products including phenols, tannins, glucosinolates, flavonoids, saponins, proanthocyanidins and cardiac glycosides were measured in Z. spinosa inhabiting different locations of Wadi Hagul during spring and summer seasons. The results of the current study showed that Z. spinosa grown in the adverse environment has adapted to cope with extreme temperature, water deficit and geoclimate changes especially in summer, by enhancing the accumulation of some antioxidant compounds including phenols, tannins, glucosinolates, flavonoids, saponins, cardiac glycosides, concomitant with increments in the total antioxidant capacity and PAL activity. Consequently, Z. spinosa shrubs inhabiting the arid environment is a promising new source of saponins, glucosinolates, cardiac glycosides, phenols and flavonoids which could participate in drug development and exploration of alternative strategies to increase productivity of wild plants.

Published: December 2017

The impact of detergent effluent on the growth, yield and foliar epidermal characters of tomato (Solanum lycopersicum L.) was investigated. The variety of tomato ((ROMA VF) was grown on soil contaminated with different concentrations (5%, 10%, 15%, 20% and 25%) of the effluent. It was observed that the effluent affected the time of germination, flowering and fruiting of the tomato plant. The number and weight of fruits produced were also affected although the extent varied with concentrations. There were significant variations in the plant height, stem girth, number of leaves, number of fruits and weight of fruits among the different treatments at 0.05 level of probability. At lower effluent concentrations, it was observed that the growth and number of fruits were relatively higher than the control (plants not treated with the effluent). The foliar anatomical study on the tomato showed that the effluent affected the structures of the plants. Significant reductions were observed in the stomata density, trichome frequency and number of epidermal cells on both the adaxial and abaxial surfaces as the concentration increases. This study revealed that detergent effluent had significant effect on the growth, yield and the foliar anatomy of Solanum lycopersicum especially at higher concentration (25%).

Published: December 2017

Effects of varying levels of Dried Poultry Droppings fed Clarias gariepinus were investigated for 84 days. The fish meal was partially and completely replaced by dried poultry droppings at 0%, 25%, 50%, 75% and 100% inclusions and was allotted T1, T2, T3, T4 and T5 respectively. Investigation conducted on the occurrence of microbes in the fish feeds revealed that T5 varied significantly (p<0.05) in Total Viable Count (TVC) (13.0×105 cfu/g) and Total Fungal Count (TFC) (0.70×105 cfu/g) respectively. The microbial properties of the fish carcass showed that T5 was significantly higher (p<0.05) in TVC (2.72×105 cfu/g), TCC (0.33×105 cfu/g), while T3 and T5 were significantly higher in TFC (0.20×103 cfu/g). The haematological parameters of Clarias gariepinus fed diet substituted with dried poultry droppings showed that Packed Cell Volume (PCV) (43.00 g/l) and Haemoglobin (Hb) (11.23 g/l) of T1 were significantly higher (p<0.05) than other treatments. The values of Red Blood Cell (RBC) revealed that T2 (3.77×106 mm3 ) was significantly different (p<0.05) compared to other treatments. The growth performance showed that T2 varied significantly (p<0.05) in Mean Weight Gain (MWG) (29.33 g) and Feed Conversion Ratio (FCR) (0.09). The findings of the current study imply that feed microbes affected the haematological parameters of the fish and equally suppressed the growth of the fish.

Published: December 2017

In order to examine the effects of different plant densities, plant patterns and irrigation regimes on yield, yield components and harvest index of grain maize, a field experiment was conducted at Miyandoab Agricultural Research Station, Iran. A strip split plot experiment was conducted based on randomized complete block design with three replications. The results showed that the effect of plant density was significant on kernel yield, harvest index, 1,000 kernel weight. The highest kernel yield was obtained from 90,000 plants ha-1 density. Maximum grain yield (18.530 t ha-1) was obtained from furrow irrigation. However, there was no significant difference between moisture levels of 100% and 120% of field capacity. The lowest kernel yield was obtained at 80% field capacity. This study also showed that mean kernel weight and the number of kernels per row were the most determinant factors in grain yield formation. The highest and the lowest harvest indices were obtained at 120% and 80% treatments of field capacity treatment, respectively.

Published: December 2017

ABSTRACT: The thermal threshold and thermal requirements of Neopamera bilobata were determined, and the number of generations that this species may produce in the main strawberry-producing regions of Brazil was estimated. In a climate chamber (70±10% RH and 12h photophase) at 16, 19, 22, 25, 28, or 30±1°C, the development of 120 eggs was monitored until the adult stage, at each temperature. Nymphs were maintained in individual cages and fed on strawberry fruits of the cultivar Aromas. The mean duration and viability of the egg and nymph stages were calculated by estimating the lower and upper developmental thresholds and the thermal constant, and this information was used to estimate the number of generations per year in different strawberry-producing regions of Brazil. The egg-to-adult duration decreased as temperatures increased, up to 28°C (93.4, 83.2, 43.9, and 31.4 days at 19, 22, 25, and 28°C, respectively). Viability of nymphs was highest between 22 and 28°C. At 30°C, the egg-to-adult duration increased (36 days), while the viability decreased (11.11%). The lower egg-to-adult developmental threshold was 15.2°C and the thermal constant was 418.4 degree-days. Calculating the number of generations indicated that the largest number (5.1 generations yr-1) was obtained for the municipality of Jaboti, Paraná, and the smallest for Caxias do Sul, Rio Grande do Sul (1.9 generations yr-1). Our findings demonstrated that important strawberry-producing regions in Brazil are suitable for the development of N. bilobata.

Abstract Despite today’s widespread reference to sustainability, initiatives are still quite incipient. Ecovillages are communities that carry out an array of sustainable practices and aim to influence society as models for alternative lifestyles. The goal of this paper is to analyze the meanings associated with these communities in the academic literature and their relevance to sustainability debates. Regardless of the conceptual imprecision of the term ‘ecovillage’ and important challenges and limitations regarding their social role in society, ecovillage initiatives (many that are educational) have propagated by diffusing alternative ideas and practices throughout society. They are increasingly linked with other movements and social institutions, functioning as key nodes in sustainability-oriented networks. As they promote concrete actions in the construction of societal alternatives, ecovillages significantly contribute to efforts of rethinking sustainability.
ANALYSIS OF ENVIRONMENTAL ATTITUDES AND BEHAVIORS: AN EXPLORATORY STUDY WITH A SAMPLE OF BRAZILIAN UNIVERSITY STUDENTS
Authors: AMÉRIGO MARÍA , GARCÍA JUAN A. , CÔRTES PEDRO L.
Published: December 2017

Abstract Models based on a multidimensional structure of environmental attitudes are more appropriate than one-dimensional or dichotomic approaches when assessing the complex relationships people have with the natural environment. This work explores a model of environmental concern composed of four attitudinal dimensions (apathy, anthropocentrism, connectivity and emotional affinity), analyzing their relationships with pro-environmental behaviors. The sample consisted of 250 students from a university that represents the most popular strata of the population, being people more susceptible to financial problems and more easily affected by adverse economic situations. The results obtained with Partial Least Square (PLS) show the validity and reliability of the proposed model, and reveal that this group believes it is possible to reconcile economic growth with environmental preservation. The results show, in addition, which strategies can be worked to increase environmental awareness related to energy saving, waste management and green consumption.
OS IMPACTOS DA POLÍTICA MONETÁRIA NA TAXA DE CÂMBIO NO BRASIL: IDENTIFICAÇÃO VIA HETEROCEDASTICIDADE
Authors: Couto Sílvia Verônica Vilarinho , Meurer Roberto
Published: December 2017

RESUMO O presente trabalho busca analisar os efeitos da política monetária brasileira sobre a taxa de câmbio, no período de 2004-2016, considerando o problema de endogeneidade da política monetária. Para tratar do problema da endogeneidade da política monetária é empregado o método de identificação via heterocedasticidade. A principal vantagem deste método é que ele se baseia no comportamento estatístico das séries, não sendo necessário realizar suposições arbitrárias de identificação. Os resultados mostram que há uma relação positiva entre a taxa de juros e a taxa de câmbio no Brasil.
SOCIAL POLICY AND STRUCTURAL HETEROGENEITY IN LATIN AMERICA: THE TURNING POINT OF THE 21ST CENTURY
Authors: Lavinas Lena , Simões André
Published: December 2017

ABSTRACT This article addresses the complementarity between social policy and pro-growth macroeconomic policies, which turned redistribution into a crucial issue to consolidate market societies through the expansion of demand. It focuses on the recent economic history of Latin America, marked by the emergence of new conceptual paradigms so as to grasp the singularities of the region´s development. Three questions are then raised: i) which social inclusion model distinguishes the new period of economic growth led by the so called social-developmentalist strategies? ii) what role is assigned to the social protection system and to social policies in general in this context? iii) which mechanisms enabled the transition towards a mass-consumption society? Brazil will serve as a case study.
Sensory profile and evaluation of the degree of acceptability of bread produced with inulin and oligofructose
Authors: Souza-Borges Patricia Kelli de , Conti-Silva Ana Carolina
Published: December 2017

Abstract Homemade bread was produced with 4.4 and 4.45 g of total fructans per 50 g serving to meet Brazilian standards for prebiotic claims. The bread samples were characterized for their sensory profiles using descriptive analysis and for their sensory acceptability using hedonic and just-about-right scales for sweetness intensity. The sensory profiles of the breads were similar and sweetness was the term that discriminated the bread samples obtained, since the intensity decreased from the bread formulated with oligofructose/inulin to the bread formulated with inulin and finally to the standard bread formulation. Comparing the crust colour of the standard bread with the crust colour of the bread with inulin, the bread with inulin was more beige, while the bread with oligofructose/inulin had smaller bubbles and was not as soft. The bread with oligofructose/inulin had a higher degree of acceptability with respect to flavour and overall acceptability than the standard bread, but the bread with fructans was preferred as compared to the standard bread in terms of appearance, aroma, texture, flavour and overall acceptability. In conclusion, the addition of fructans to bread formulations is promising and may promote the elaboration and consumption of new prebiotic products in the bakery line.

RESUMO A Estação de Pesquisa e Desenvolvimento Ambiental de Peti, um mosaico sucessional, localizase na região mineradora do Alto Rio Doce, bacia do rio Santa Bárbara. Os objetivos deste estudo foram determinar a estrutura fitossociológica de cinco áreas de floresta em diferentes estádios sucessionais e avaliar relações entre vegetação e solo. Em cada área foram amostrados 48 pontos-quadrantes e medidas as alturas e circunferências (≥ 15 cm) dos troncos das árvores. No total, foram identificadas 45 famílias, 116 gêneros e 191 espécies. As famílias com maior número de espécies foram Fabaceae, Myrtaceae, Lauraceae, Melastomataceae, Euphorbiaceae, Rubiaceae. Pogonophora schomburgkiana, Cupania ludowigii, Astronium fraxinifolium e Mabea fistulifera foram espécies de maior valor de importância. A altura média dos indivíduos variou, entre as áreas, de 7,1 ± 2,1 a 9,2 ± 3,4 m e o diâmetro médio de 8,9 ± 5,1 a 12,1 ± 7,1 cm. Duas áreas apresentaram constituição florística diferentes, de acordo com o resultado da análise de similaridade. O índice de diversidade de Shannon para espécies foi 4,58 nats/indivíduo, o que indica alta diversidade, resultante da presença de mosaico sucessional. A área que sofreu corte seletivo apresentou maior riqueza florística em comparação as demais áreas estudadas, estando todas sobre solos pobres em nutrientes e com altos níveis de alumínio.

RESUMO As florestas semidecíduas na Bahia mostram-se bastante fragmentadas e têm sido pouco estudadas em relação à florística e à fitogeografia. Estas florestas estão situadas principalmente no semi-árido e isoladas da Mata Atlântica costeira por extensas áreas de caatinga. Este trabalho apresenta o levantamento florístico de um fragmento de floresta semidecídua na Serra da Fazenda Retiro (SFR), localizada no município de Feira de Santana, Bahia, com o objetivo principal de avaliar a sua posição fitogeográfica em relação às caatingas e à Mata Atlântica. Foram amostradas 173 espécies incluídas em 143 gêneros e 59 famílias. Myrtaceae foi a família que apresentou o maior número de espécies (15 spp.), seguida por Euphorbiaceae (13), Leguminosae (12), Malvaceae (7), Orchidaceae (7) e Rubiaceae (7). Além disso, foram coletadas três novas espécies dos gêneros Neomarica (Iridaceae), Pseudobombax (Malvaceae) e Solanum (Solanaceae). As análises de agrupamento pelo método UPGMA e de composição de espécies da SFR mostram que a área, apesar de estar situada dentro do Bioma Caatinga, apresenta uma maior relação florística com as florestas semidecíduas do Domínio da Floresta Atlântica.

O princípio responsabilidade de H. Jonas como contraponto ao avanço (ir)responsável das nanotecnologias
Authors: Hupffer Haide Maria , Engelmann Wilson
Published: December 2017

Resumo: O objetivo do presente artigo é realizar um diálogo com Hans Jonas, buscando identificar o papel pedagógico do Princípio Responsabilidade e se o mesmo contribui para fundamentar uma nova ética de responsabilidade frente ao avanço (ir)responsável das nanotecnologias. A partir do método fenomenológico-hermenêutico, a hipótese que se desenha tem o contorno do cuidado (referencial teórico de Martin-Heidegger e Hans Jonas) como elemento estruturante necessário para avaliar e projetar as consequências dos avanços das nanotecnologias na perspectiva intergeracional. As concepções teóricas que deram apoio ao estudo permitem indicar que Jonas, ao resgatar filosoficamente o tema da promessa utópica e perigosa das novas tecnologias, avança em relação à ética tradicional ao apontar pela necessidade de uma responsabilidade moral coletiva que também se estende para as futuras gerações.

Published: December 2017

Abstract: Salinity and water deficit limit the productivity of several crops; thus, studies related to the genetic transformation of seeds in a model plant, such as tobacco, can be an alternative to minimize negative impacts caused by environmental conditions. The purpose of this work was to evaluate the tolerance to osmotic stress of seeds from genetically transformed tobacco plants, with the introduction of the proline-synthesizer gene (p5csf129a), under salinity and water deficit conditions. To do so, five events with differences in proline content were selected, ranging from 0.70 to 10.47 µmoles.g-1 of fresh mass. The used saline concentrations were: zero (distilled water); 50; 100; 150 and 200 mmol.L-1 of NaCl, whereas for the water deficit, simulated with PEG 6000, the following osmotic potentials were used: zero (distilled water); -0.2; -0.4; -0.6 and -0.8 MPa. Each tested treatment was evaluated through germination, first germination count and germination speed index tests. It is possible to conclude that seeds from genetically transformed tobacco plants with overexpression of the gene p5csf129a, a proline synthesizer, are more tolerant to osmotic stresses. Tabacco seeds with a proline content of 10.47 µmol.g-1 showed a better perfomance, revealing higher physiological potential.
