Authors: Cunha Ricardo Borges da , Martins César Augusto Ávila
Published: May 2017

A afirmação dos processos eleitorais como uma das formas de organização política é objeto de investigação de várias ciências. No concerto das ciências, o Direito, a Sociologia e as Ciências Políticas destacam-se nas análises das eleições. As eleições como resultado de disputas entre determinados projetos, tem a função de eleger representantes para conduzir as instituições políticas. A perspectiva esta coadunada com o entendimento que as eleições são um dos momentos de manifestação de poder com diferentes graus de visibilidade, numa dada formação social com determinados regramentos e em cada conjuntura. O processo que articula determinados agentes pode ser compreendido em etapas e em seu conjunto. O artigo busca trilhar alguns dos caminhos da Geografia Eleitoral compreendida na Geografia Política, como um campo de análise geográfica das eleições, conhecendo sua evolução, apontando possibilidades e desafios. Metodologicamente, o texto realiza uma revisão de algumas das diferentes metodologias da Geografia Eleitoral, que são baseadas sobretudo na apresentação dos resultados eleitorais ao longo tempo e que tendem encerrar sua abordagem ao final de cada pleito. O texto advoga que a adoção de um modelo sistêmico, como uma alternativa para a compreensão de um pleito, integra os resultados das urnas e as suas consequências para vida política.ABSTRACTThis paper aims at introducing not only some of the directions of Electoral Geography in the light of Political Geography, as a field of geographical analysis of elections, but also its evolution, possibilities and challenges. Meaning is found in electoral processes as one of the forms of political organization which has become the object of investigation of sciences, such as Law, Sociology and Political Sciences. Elections, as the result of dispute among certain projects, play the role of choosing representatives to lead political institutions. This perspective agrees with the fact that elections represent a moment of power manifestation at different levels of visibility, with certain rules in each situation. Regarding methodology, this text reviews some proposals of Electoral Geography which are mostly based on the presentation of electoral results over time and tend to end their process at the end of each dispute. Among the selected authors, it is clear the growth of the geographical field with the quantitative methods, but the approaches did not connect the electoral process with the politics practiced in the perimeter involved leaving a gap to be completed. The text defends the use of the systemic model so as to understand the dispute as a moment of political life with integration among the phase that precedes elections, its results and its consequences for democracy.

O Litoral Norte paulista constitui um dos principais polos turísticos do Estado. A atividade de mineração, principalmente dos materiais de empréstimo (saibro), apesar de ter deixado um legado negativo ao longo dos últimos 30 anos, sempre serviu de suporte para o desenvolvimento urbano, o que possibilitou o incremento da atividade turística na região. O presente estudo teve como objetivo identificar e quantificar os remanescentes da mineração de saibro, que apresentassem degradação do meio ambiente e risco às comunidades locais, com o intuito de classificar estas áreas quanto ao seu potencial de aproveitamento para exploração de recursos minerais. Para isso lançou-se mão dos sistemas de informações geográficas para gerar um modelo digital de elevação, a partir de redes irregulares triangulares (TIN) e se obter o volume das áreas. Posteriormente estas informações foram integradas com os dados de degradação e risco para se chegar ao potencial de aproveitamento das áreas para a mineração. Os resultados alcançados mostram que as 33% das 226 áreas mapeadas apresentam alto potencial para aproveitamento de bens minerais, sendo capazes de sustentar a demanda de suprimentos de baixo valor unitário utilizados na construção civil. O aproveitamento também pode trazer benefícios ambientais uma vez que é capaz de minimizar os riscos ambientais deixados pelas frentes de lavra abandonadas e restringir a ampliação das áreas mineradas.ABSTRACTThe North Coast of São Paulo is one of the major tourist centers of the State. The mining activity, especially of borrow materials (saibro), despite having left a negative legacy over the past 30 years, has always been the support for urban development, which enabled the growth of tourism in the region. This study aimed to identify and quantify the remnants of saibro mining, with environmental degradation and risk to local communities in order to classify these areas by their potential for mineral resources exploitation. Geographic Information Systems (GIS) were applied to generate a Digital Elevation Model (DEM) from a Triangular Irregular Network (TIN), obtaining the volume of those areas. Subsequently, this information was integrated with the degradation and risk data to reach the potential use of areas for mining. The achieved results show that 33% of 226 mapped areas have high potential for exploitation of mineral resources, being capable of sustaining the demand for low unit value supplies used in construction. The use can also bring environmental benefits as it is able to minimize natural hazards left by the abandoned mining fronts and restrict the expansion of mining areas.

Attitudes of Students Enrolled in the Pedagogical Formation Programs towards the Teaching Profession
Authors: Ozdemir Yalcin , Gungor Sabri
Published: May 2017

This study was conducted to examine the attitudes of students enrolled in the pedagogical formation programs in order to become teachers towards the teaching profession. The students either graduated from faculties other than the education faculty or they were still enrolled in undergraduate programs of faculties other than the education faculty. The study group is made up of randomly selected 491 students enrolled in the pedagogical formation programs of Kafkas University and Ömer Halisdemir University during the 2016-2017 academic year between 6 and 15 January, 2017. To collect the study data, “Attitude Scale towards Teaching Profession” was used. Arithmetic mean, independent t-test, one-way analysis of variance (ANOVA) and LSD post hoc tests were conducted in the analysis and interpretation of data. In the study, it was determined that as the ages of students enrolled in the pedagogical formation programs increase, they showed more positive attitudes towards the teaching profession. Females had more positive attitudes than males, graduates more than students, Ömer Halisdemir University students more than Kafkas University students, and students who lived mostly in urban areas more than students who live in rural areas. Furthermore, according to the study results, teaching profession attitudes of students enrolled in pedagogical formation programs differ according to their faculty, mother and father’s education and monthly family income.

The aim of this study was to evaluate the effects of vegetable glycerin on performance and egg quality of red-egg layers in the second production cycle. A total of 252 Hy-Line Brown layers weighing 1.919 ± 0.095 kg, at 90 weeks, were used in a completely randomized design with six treatments and seven birds per replication. The experiment lasted 84 days. Treatments consisted of a control diet (no glycerin) and five diets with increasing levels of vegetable glycerin (2, 4, 6, 8, and 10%). The following variables were evaluated: feed intake (g/bird/day); egg production (%); egg weight (g); egg mass (g/bird/day); conversion per egg mass (kg kg) and per dozen eggs (kg/dz); percentages of albumen, yolk, and shell; eggshell thickness (mm); and egg specific gravity. (Y = 67.69 + 54.23X, R2 = 0.78) and egg mass (Y = 44.84 + 42.87X, R2 = 0.66) improved linearly with the glycerin levels. A quadratic effect was observed (Y = 114.11 + 336.96 X – 3,169.6 X2, R2 = 0.52) on feed intake. In conclusion, glycerin can be used to partially replace corn in diets for layers in the second production cycle at inclusion levels of up to 10%.

Published: May 2017

Sugarcane plays an important socio-economic role in northeastern Brazil. However, the low yield in this region is associated with several factors (e.g. frequent occurrence of plant-parasitic nematodes). In order to observe the influence of soil organic matter on the nematodes, this study aimed to characterize the spatial nematode distribution in a sugarcane field. The study was carried out in Goiana - Pernambuco State (Brazil), fifty days after sugarcane cutting (10 days after vinasse application). The sampling scheme consisted of a regular 60 × 50-m grid, 10 m spaced, through 0 to 0.2 m depth. Spatial distribution was evaluated by semivariograms fit and performed by ordinary kriging interpolation for mapping. Exponential and spherical models promoted the best fit to semivariograms, resulting in ranges from 16 to 19 m. There was a strong negative correlation between soil organic matter and plant-parasitic nematode population density. Free-living nematodes had a similar distribution pattern as soil organic matter content. These results indicated that soil organic matter had important effects on spatial distribution of both plant-parasitic and free-living nematodes.

Published: May 2017

The aim of this study was to evaluate the residual effect of phosphorus (P) fertilizer applied to an Urochloa decumbens cv. Basilisk pasture on the P bioavailability to the following soybean crop. Low-productivity pasture, planted on an Oxisol in an experimental field at Embrapa Cerrados, was divided into three strips, each of 1.5 ha and fertilized by broadcasting annual applications of 0, 20 and 40 kg ha-1 of P2O5 for four years. After the pasture was desiccate with herbicide, soybeans were sown and fertilized with 0, 50 and 100 kg ha-1 of P2O5 applied within each strip, making a total of nine (3x3) P treatments. Residual available P content (Mehlich-1 and resin) from the pasture fertilization was lower than from soybean fertilization. However, the bioavailable residual P from the pasture, determined by P accumulated in plants, production of dry matter and grain yield, had similar availability to inorganic P applied to the soybean. Early P fertilization applied to pasture is technically feasible and can be used to maintain the pasture: it is recommended to replace corrective fertilization for following soybean crops.

This study evaluated the residual compost from the production of Bactris gasipaes Kunth (pupunha heart of palm) (RP) and the mushroom Pleurotus ostreatus (RM). The residuals were used as soil conditioners for Lactuca sativa ‘Veronica’ crops. After adding RP and RM to the soil, all treatments exhibited similar behaviors and soils in each treatment were classified as eutrophic. Soil treatments involving increased application of residual compost resulted in the production of lettuce with greater widths because of an increase in the angle between the stem and leaf, resulting from a lack of nitrogen available to the plant. Soil treatments with 5% of RP and RM resulted in a 1.7 and 1.2 times (44% and 22%, respectively) decrease in dry weight of lettuce, as compared to the soil without residual compost addition. The addition of RP and RM as soil substrate reduced the growth of lettuce compared to the soil without residual compost. In general, the possibility of replacing chemical fertilizers (NPK) with RP or RM without previous composting was found to be inefficient. The resultant dry weight parameters were below the commercial level, and a complete period of composting RP and RM was deemed necessary for incorporating nitrogen into the soil. Lignocellulosic mushrooms such as Pleurotus spp. present highly fibrous residual compost with low nitrogen content, thus requiring a full period of composting before subsequent use in soil enrichment for various crops.

Azospirillum brasilense plays an important role in biological nitrogen fixation (BNF) in grasses. However, further studies are needed to define how much mineral N can be applied while simultaneously maintaining BNF contribution and maximizing crop yield and to determine the impact of these practices on soil fertility. Thus, we aimed to investigate the effect of inoculation with A. brasilense, in conjunction with varying N doses and sources in a Cerrado soil, on soil chemical attributes after two years of irrigated wheat production. The experiment was initiated in Selvíria - MS under no-tillage production in an Oxisol in 2014 and 2015. The experimental design was a randomized block design with four replications, and treatments were arranged in a 2 x 5 x 2 factorial arrangement as follows: two N sources (urea and Super N - urea with inhibitor of the enzyme urease NBPT (N - (n-butyl thiophosphoric triamide))), five N rates (0, 50, 100, 150 and 200 kg ha-1), and with or without seed inoculation with A. brasilense. The increase in N rates did not influence the chemical soil attributes. Super N acidified the soil more compared to urea. A. brasilense inoculation reduced the effect of soil acidification in intensive irrigated wheat cultivation; however, the base extraction was higher, resulting in a lower soil CEC after cultivation with inoculation. Therefore, the cultivation of wheat inoculated with A. brasilense was not harmful to soil fertility because it did not reduce the base saturation and organic matter content (P, K, Ca, Mg, and S).

The aim of this study was to determine agronomic characteristics and responses to the coffee leaf rust fungus (Hemileia vastatrix Berk. et Br.) in coffee progenies resistant to the gall nematode Meloidogyne exigua. The experiment was conducted in December 2000 at Ouro Verde Farm (FazendaOuro Verde), located in the municipality of Campos Altos – Minas Gerais (MG). Ten F3:4 progenies were evaluated. They were derived from crosses between CIFC 2570 Timor Hybrid selections and Catuaí cultivars known to be resistant to M. exigua. The Catuaí Vermelho IAC 99 cultivar served as a control. A randomized block design with three replicates was used. In total, there were thirty-three plots consisting of eight plants each. The following characteristics were assessed between the harvests of 2011/2012 and 2014/2015: (a) yield expressed as processed coffee bags ha-1; (b) rust incidence and severity; (c) vegetative vigor; (d) percentage of coffee fruits at the “cherry” stage; (e) percentage of floaters; (f) crown diameter; (g) percentage of coffee beans of size sieve 17 and higher; and (h) sensory analysis of the coffee beverage. The results indicated the following: (a) the H514-7-14-2, H514-7-4-5, H493-1-2-2, H514-7-16-3, H514-7-8-11, H518-2-10-1, and H514-5-2-4 progenies were the most productive; (b) all progenies showed promising resistance to coffee leaf rust; (c) all genotypes had the potential for specialty coffee production; (d) the H493-1-2-2 progeny showed resistance both to rust and the nematode, and has good potential for specialty coffee production; and (e) the yields of the H514-7-8-11, H518-2-10-1, H514-5-2-4, H514-7-16-3, H514-7-14-2, H514-7-4-5, and H493-1-2-2 progenies were significantly higher than that of the Catuaí IAC 99 control.

This study analysed parasite contamination in green leaf lettuce (Lactuca sativa), grown in different cultivation systems (conventional, organic, and hydroponic), from a family farmer cooperative in the municipality of Presidente Prudente, São Paulo, Brazil. Samples were collected at weekly intervals during five months, totalling 180 vegetable samples (60 samples of leaf lettuce from each cultivation system). Lettuce leaves were washed with 0.5% Extran MA 02, and the resulting fluid subjected to sedimentation and centrifugal flotation for recovery of parasite structures. Overall, 71 samples (39.4%) were contaminated with at least one parasite structure, 34 (47.9%) from lettuce grown in the hydroponic system, 20 (28.2%) from the organic system, and 17 (23.9%) from the conventional system. Entamoeba spp. cysts were the most common parasite structures found in the leafy vegetables, with the highest cyst counts found in the hydroponic system (p = 0.003). It is concluded that, regardless of the cultivation system (conventional, organic, or hydroponic), there is a possibility of green leaf lettuce contamination by intestinal parasites. Measures that improve sanitary conditions during production, as well as proper hygiene during the preparation of raw leafy vegetables, may be important to reduce contamination and consequent transmission of parasite diseases from raw leafy vegetable consumption.

This study aimed to evaluate the effect of different rearing densities during brooding (0 to 2 weeks) and growth (3 to 15 weeks) on performance and egg quality of laying hens (Hy-line W-36) during production phase (18 to 42 weeks). In the brooding phase, a total of 3250 day-old chicks were allocated in wire cages, distributed in a completely randomized design composed of 5 treatments (63.57; 66.38; 69.44; 72.80 and 76.50 cm²/bird) with 10 replications each. At the beginning of the growth phase, floor space in each treatment was increased. Therefore, a total of 750 birds were selected from the original treatments, which represented 237.57, 265.52, 300.92, 347.22, and 410.35 cm²/bird. At the end of the growing phase, 390 pullets were transferred to production facilities and distributed, according to their original treatment, in conventional cages with 430.76 cm²/bird (13 birds/cage). For this phase, only 6 replications per treatment were adopted. Experimental data were subjected to analysis of variance and, in the case of significant differences, means were analyzed using polynomial regression test. Body weight, weight gain and uniformity were compared during the brooding and growth phases. First-egg weight, age at first egg, age at 50% daily production, weights of egg, albumen, yolk and shell, egg mass, yolk diameter, yolk height, yolk index, albumen height, percentages of shell, albumen and yolk, shell thickness, Haugh unit, and egg specific gravity were analyzed during the production stage. In conclusion, raising pullets on 63.57 cm2/bird (71 birds/cage) does not affect chicks’ performance during the brooding phase. However, for the growth phase, the recommendation is to provide 410.35 cm2/bird, which corresponded to 11 birds/cage in this research. For the production period, the recommendation is to utilize pullets raised on 265.52 cm2/bird, which corresponded to 17 birds/cage on this research.

This study investigates the methane and carbon dioxide gas production, dry matter degradation, and final pH values obtained during the in vitro incubation of corn grain, soybean hulls, citrus pulp, corn silage, and crude glycerin. Experiments were performed using a randomized block design with four incubation periods. Each period featured four replicates per ingredient and four blanks, totaling 16 repetitions per ingredient. The lowest total amount of produced gas (37.96 mL gincubated DM-1) and the lowest final pH value (4.95) were obtained for crude glycerin (P < 0.05), which, however, exhibited the highest (P < 0.05) DM degradation. Citrus pulp produced the largest amount (P < 0.05) of CH4 per gram of incubated DM (13.56 mL g-1). However, when methane production was expressed per gram of degraded feed, the ingredients with lower degradation values, such as soybean hulls and corn silage, produced more CH4 per gram of degraded DM. Citrus pulp and corn grain produced more (P < 0.05) CO2 per gram of incubated DM. However, per gram of degraded food, citrus pulp produced the largest amount of CO2 (P < 0.05). Crude glycerin and corn grain produced less methane (per gram of degraded feed) than citrus pulp, soybean hulls, and corn silage. Differentiation of ingredients based on their methane production ability is important to express methane production per unit degraded food mass.

An experiment was carried out to investigate the effects of supplementation strategies on intake, digestibility, and performance of Nellore cattle on pasture (Urochloa decumbens) during the rainy-dry transition period. The evaluated strategies were mineral supplementation (MS), self-feed supplementation (SF), and infrequent concentrate supplementation. Supplementation frequencies were three times per week (Mondays, Wednesdays, and Fridays - 3tw) and daily (7tw). Animals receiving concentrate supplementation had higher pasture DM and TDN intakes than those fed MS. There was no difference (P > 0.10) between concentrate supplementation strategies. Average pasture DM intake was 7.89, 8.09, and 8.10 kg day?1 for SF, 3tw, and 7tw, respectively. No effects were found (P > 0.10) between SF and infrequent supplementation, or for the supplementation frequencies tested. The lowest average daily gain (ADG) (P < 0.10) was found for animals fed MS, and there was no difference between concentrate supplementation strategies for this variable. Average daily gains for MS, SC, 3tw, and 7tw were 661.4, 812.7, 811.5 and 819.2 g/animal, respectively. During the rainy-dry transition period, grazing beef cattle receiving concentrate supplementation have higher pasture and TDN intakes and better performance than animals fed mineral supplement only. Self-feed supplementation or supplementation provided three days per week do not compromise pasture and TDN intakes, nutrient digestibility, or performance of grazing beef cattle.

Published: May 2017

Measurement and evaluation of the factors that may influence milk composition has been shown to determine the actual gains in milk quality and quantity. The study was conducted to evaluate the influence of daily milk yield on the physicochemical composition of milk and analyze the correlations between milk yield and somatic cell count (SCC) on the fat, protein, lactose, total solids and nitrogen urea contents in Holstein cows’ milk. A total of 3,544 data collected from 467 cows were evaluated. In the analysis, the animals were divided into groups – I (5-15 kg milk day-1), II (15-30 kg milk day-1) and III (above 30 kg milk day -1) – based on their daily production. Animals of Group I had higher SCC (P < 0.05) and fat and protein percentage when compared with Group III. However, the lactose content was lower (P < 0.05) than Group II and III. No correlation (P > 0.05) between SCC and fat, protein and total solids contents was observed. A lower milk yield is significantly associated with a higher SCC, which, besides hindering the quality of milk, compromises the cow's udder health.

The effects of diet supplementation with ?-tocopherol acetate (VE) and selenium yeast (SeL) on the water holding capacity (WHC), cooking weight loss (CL), drip loss (DL), pH, colour and selenium concentration of the breast of chickens fed diets based on corn or brown rice were studied. From 21 days of age, a total of 200 birds were housed in 38 floor pens (experimental unit) in a randomised 23 factorial arrangement. The levels of supplementation were VE (0 and 200 mg/kg), organic selenium (0 and 0.3 ppm) and two diets (100% corn and 100% brown rice) in a total of eight treatments: T1) corn + 0 SeL + 0 VE (control); T2) corn + 200 mg/kg VE + 0 SeL; T3) corn + 0 VE + 0.3 ppm SeL; T4) corn + 200 mg/kg VE + 0.3 ppm SeL; T5) brown rice + 0 VE +0 SeL; T6) brown rice + 200 mg/kg VE + 0 SeL; T7) brown rice + 0 VE + 0.3 ppm SeL; T8) brown rice + 200 mg/kg VE + 0.3 ppm SeL. The concentration of selenium in the breast increased with VE supplementation in the diet (P < 0.001). However, a positive interaction between VE and SeL on selenium concentration in the meat was found (P = 0.06). A better WHC with the inclusion of SeL and VE was found only in the rice-based diets. The replacement of corn by brown rice decreased (P < 0.05) the yellowness of the meat. CL and DL were not significantly affected by the treatments. Broilers fed with SeL supplemented diets showed a higher pH in the breast than diets without supplementation. In conclusion, the interaction between VE and SeL increased selenium in meat but improved WHC only in rice-based diets. The replacement of corn by brown rice decreased the yellowness of chicken breast meat.

Published: May 2017

En el año 2011, en torno al movimiento 15M, miles de españoles se conectaron a Twitter para convocarse, organizarse y gestionar encuentros en plazas públicas, para protestar por el detrimento progresivo de su estado de bienestar social. Esta investigación, de enfoque cuantitativo, se propuso identificar las tendencias en los temas de interés en 17.599 tuis publicados por la red de conexiones de 14 usuarios vinculados al movimiento 15M y su relación con la estructura de la red de comunicación que emergió de estos tuits. Para identificar la estructura de dicha red se usó el método de Análisis de Redes Sociales (ARS) usando NodeXL. Para detectar las tendencias de los temas de interés, se aplicaron técnicas de minería de texto, usando Excel y T-Lab. Se encontró que Twitter jugó un importante papel en la difusión de la información, en las convocatorias y en la organización del movimiento 15M; las tendencias en los hashtags estaban orientadas a visibilizar el movimiento y a invitar a las actividades programadas, y las de los lemas a organización (Asamblea, seguir, gente, democracia) y a espacios físicos (calle, plaza). Finalmente, se encontró una relación directa entre las métricas de la red y las tendencias de los temas de interés.

A Maçonaria vem sendo estudada pela academia principalmente sob as perspectivas histórica e filosófica. O presente trabalho aborda a Ordem Maçônica sob um prisma distinto, uma vez que analisa as relações sociais desenvolvidas dentro da estrutura de uma Loja Maçônica a partir da aplicação da análise de redes sociais. A pesquisa caracteriza-se como exploratória e descritiva e mapeia das relações sociais estabelecidas entre os membros de uma Loja Maçônica do Distrito Federal. Os resultados alcançados permitiram caracterizar os padrões de relacionamentos estabelecidos por subgrupos presentes na Loja estudada e evidenciaram a evolução dos relacionamentos entre seus membros estabelecidos a partir da entrada na Loja. Pode-se observar que, quando da entrada na Ordem, há uma predominância dos contatos sociais em detrimento dos contatos institucionais, ainda que haja uma estrutura organizacional estabelecida e cargos responsáveis por esse contato inicial. Conforme esperado, os membros da Gestão da Loja ocupam uma posição central na rede de relacionamentos, no entanto a frequência dos membros em Loja é uma variável tão ou mais importante do que o nível de formação dos membros (representado pelo Grau Simbólico) ou sua participação na administração da organização para explicar o grau de centralidade dos atores.
KAZIMIERZ MALINOWSKI – MUSEUM PROFESSIONAL
Authors: Radecki Gerard
Published: May 2017

Year 2017 marks the 110th birthday anniversary and 40th anniversary of the death of Kazimierz Malinowski. June 2016 marked half a century since he re-took the post of Director of the National Museum in Poznań. The circumstances in question require us to remember an individual who was of great merit to Polish museology and to the National Museum in Poznań. The title of this text paraphrases the title of an article by Kazimierz Malinowski Michał Walicki - museum professional, published in the “Muzealnictwo” magazine and devoted to a renowned art historian and researcher on Gothic art in Poland. Walicki is less known as a museum professional and even less as a mentor to Malinowski himself. However, if one attempted to determine the whole range of the activity of the latter using one word only, the term “museum professional”, rather disregarded today, seems to be the most capacious and adequate. It reminds about Malinowski in some of the most significant aspects of his activity, including the one as: 1/ a museum professional in the strict sense, but also a practician working in a museum and taking part in the life of this environment in the broadest meaning, 2/ a propagator of the social role of museums as institutions open to the general public, 3/ the long-term Director of the National Museum in Poznań, a visionary and a curator of the institution’s new programme. Malinowski was one of a few of the most important figures of the post-war museology in Poland. Today, he is almost entirely forgotten. Almost total absence of this name in today’s museum circles also results from an unsatisfactory state of research into his professional biography. Nevertheless, Malinowski’s activity, even only in the field of museology, as his second major field of activity was conservation, is still to be meticulously analysed. Therefore, many opinions presented below should be treated as suggestions and hypotheses, still to be further verified, given the current state of research. However, his main fields of activity have been roughly, as it may seem, sketched out in this article. They present him as a propagator of the social role of museums – institutions open to the general public, which, in turn, will prove the topicality of Malinowski’s suggestions in comparison with current discussions on museums’ functions.

The End of Academic Freedom in the Era of Neoliberalism?
Authors: Lojdová Kateřina
Published: May 2017

Tento článek diskutuje možné konsekvence neoliberalismu pro současné university. Zaměřuje se v perspektivě kritické pedagogiky na možné konflikty neoliberalismu s akademickou svobodou jakožto hlavní součástí akademického ducha na univerzitách. Článek je rozdělen do dvou částí. První část přibližuje kritickou pedagogiku, její kořeny a současnou podobu, včetně limitů, které tento koncept má. Druhá část se již v kriticko-pedagogickém pohledu věnuje neoliberální proměně výzkumu a výuky na univerzitách na příkladu pedagogických fakult. Závěr nastiňuje možnosti kritické pedagogiky k pěstování akademického ducha na univerzitách. Shledává je například ve výzkumu nezávislém na grantových schématech, avšak relevantních pro odbornou komunitu, v citlivém managementu univerzit a v kurikulu pregraduální přípravy učitelů akcentujícím spíše svobodného učitele nežli kompetenční orientaci vzdělávání diktovanou shora. Článek tak ústí do smířlivé vize udržitelného akademického života, která balancuje na pomezí mezi ekonomickou dimenzí univerzit na straně jedné a akademickou svobodou nezávislou na trhu práce na straně druhé.
Representando o conhecimento da inflamação crônica através da Ontocancro

Published: May 2017

O projeto Ontocancro foi criado com objetivo de integrar dados, de bases de dados públicas, de genes referentes ao câncer. Ao longo das pesquisas descobriu-se o conceito da inflamação crônica e sua relação com doenças como alzheimer, diabetes tipo 2 e o próprio câncer. Assim, optou-se por atualizar a ontologia unificando o estudo do câncer das versões anteriores da Ontocancro e as especificações da inflamação crônica, inserindo informações novas sobre as doenças citadas anteriormente. A atualização da ontologia para a versão 3.0, apresentada neste trabalho, seguiu os passos propostos por Noy e McGuiness e ainda utilizou a ferramenta Protégé. Além disso, atualizou-se o banco de dados relacional para que esse refletisse os conhecimentos inseridos na nova versão da ontologia. Como resultados são apresentados dados de outras ontologias existentes comparados com os dados da ontologia desenvolvida nesse artigo.

Se presenta una recopilación de los resultados de varios proyectos, desarrollados entre los años 2004 y 2015, sobre la presencia de los mosquitos de la familia Culicidae en el entorno de la Devesa y el Racó de l’Olla del Parque Natural de l’Albufera de Valencia (España). Se registró un total de 10 especies pertenecientes a cinco géneros (Aedes, Coquillettidia, Culex, Culiseta y Ochlerotatus), alguno de estos muy característicos de los ambientes donde fueron recolectados. Se tratan diferentes aspectos sobre la diversidad de culícidos, así como del interés ecológico y sanitario de la presencia de los mismos. Destacamos la existencia de la especie Aedes albopictus (Skuse, 1894) en un espacio acotado por viviendas, construidas en los años 1970, y no recolectada en las malladas.

A compilation of the results obtained in several projects developed between the years 2004 and 2015 on the presence of the mosquitoes of the family Culicidae in the surroundings of the Devesa and Racó de l'Olla of the Albufera Natural Park of Valencia (Spain). A total of 10 species belonging to five genera (Aedes, Coquillettidia, Culex, Culiseta and Ochlerotatus) were recorded, some of them very characteristic of the environments where they were collected. Different aspects are discussed on the culicid diversity, as well as on the ecological and health interest of the presence of these species. We highlight the presence of the species Aedes albopictus (Skuse, 1894) in a space limited by housing, built in the 1970s, and not collected in the malladas.

Humans treat unreliable filled-in percepts as more real than veridical ones

Published: May 2017

Humans often evaluate sensory signals according to their reliability for optimal decision-making. However, how do we evaluate percepts generated in the absence of direct input that are, therefore, completely unreliable? Here, we utilize the phenomenon of filling-in occurring at the physiological blind-spots to compare partially inferred and veridical percepts. Subjects chose between stimuli that elicit filling-in, and perceptually equivalent ones presented outside the blind-spots, looking for a Gabor stimulus without a small orthogonal inset. In ambiguous conditions, when the stimuli were physically identical and the inset was absent in both, subjects behaved opposite to optimal, preferring the blind-spot stimulus as the better example of a collinear stimulus, even though no relevant veridical information was available. Thus, a percept that is partially inferred is paradoxically considered more reliable than a percept based on external input. In other words: Humans treat filled-in inferred percepts as more real than veridical ones.
