Citation patterns in Educational Science theses at the University of Córdoba

This paper analyses citation patterns in 30 doctoral theses in the field of Education Sciences, submitted at the University of Córdoba (Spain) between 1997 and 2010. A preference was found for citing books as opposed to articles. The most widely-cited journal was a Spanish education-specific publication, Enseñanza de las ciencias. Only a small number of journals from the stock of periodical publications held and managed by the Faculty of Education Sciences Library were cited

Demandas de atendimento psiquiátrico em um hospital universitário Demandas de lo atendimiento psiquiátrico en un hospital universitario Demands of psychiatric care in a university hospital

Estudo transversal que objetivou descrever a demanda psiquiátrica em um hospital universitário de Cuiabá, Mato Grosso, e conhecer a situação atual de atendimento a essa demanda. Os dados foram coletados nos prontuários dos pacientes internados em um hospital universitário, de junho-agosto de 2009, constituindo uma amostra de 551 prontuários. Apesar de apontada pela literatura como despreparada, a enfermagem é a categoria profissional que mais identifica a demanda psiquiátrica existente neste hospital. O plano de tratamento a essa demanda se restringiu a medicação, nove avaliações de psicologia e 13 de interconsulta médica psiquiátrica, sem participação significativa da enfermagem. A abordagem de aspectos emocionais e/ou mentais repercute em melhoria na qualidade da assistência de enfermagem, sendo necessário que os enfermeiros se capacitem para isto. Para viabilização disto sugerimos uma reflexão sobre a necessidade da interconsulta de enfermagem psiquiátrica neste hospital.<br>Estudio transversal, tuvo como objetivo describir la demanda psiquiátrica en un hospital universitario de Cuiabá, Mato Grosso, Brasil, y conocer la situación actual de atendimiento para esa demanda.

The data were collected from the inpatient medical records in a university hospital, from June to August, 2009, in a total of 551 records. Despite being considered by the literature as unprepared, nursing is the professional category that most identifies the psychiatric demand in this hospital. The treatment plan to this demand was restricted to medication, nine evaluations of psychology and thirteen consultation-liaison psychiatric service, without a significant involvement of nursing. The approach of emotional and/or mental aspects results in the improvement in the quality of nursing care, and there is a need for the nurses to qualify for that. To make it happen, we propose a reflection on the need for the consultation-liaison psychiatric service in this hospital

Inoculation with Azospirillum, associated with nitrogen fertilization in maize

The biological nitrogen fixation is an alternative to supply the nitrogen needed for maize. The objective of this study was to evaluate the development and yield of maize in response to inoculation with Azospirillum associated with nitrogen fertilization. We conducted two field experiments in the summer harvest, the first in the 2000/2001 crop year in the region of Marechal Cândido Rondon, under conventional tillage, and second in the 2002/2003 agricultural year in the region of Cascavel, under no tillage. The experimental design in both experiments was a randomized complete block, with four replications, 2x2x2 factorial, with two levels of nitrogen at sowing (zero and 20 kg ha-1), two levels of inoculum (zero and 200 g ha-1) and two levels of nitrogen in topdressing (zero and 100 kg ha-1). There was evaluated the height of ear insertion, total plant height, leaf N content, shoot dry biomass and grain yield. The height of ear insertion and total plant height were not influenced by the factors under study. Nitrogen fertilization at sowing increased the leaf N content, causing the opposite effect when combined with inoculation. Inoculation with Azospirillum in the absence of nitrogen, provide productivity increases of 15.4% and 7.4% for 2000/2001 and 2002/2003 crops, respectively. The inoculation provided productivity similar to that obtained with 100 kg ha-1 in topdressing in crop 2000/2001, while in association with the topdressing, reduced productivity and shoot dry biomass in crop 2002/2003

Proteocephalid cestode infection in alien fish, Cichla piquiti Kullander and Ferreira, 2006 (Osteichthyes: Cichlidae), from Volta Grande reservoir, Minas Gerais, Brazil

This work evaluates the variation of the parasitological indexes in 114 Cichla piquiti Kullander and Ferreira, 2006 (tucunaré) infected by two proteocephalid species (Cestoda) for the period of August 1999 to June 2001 in the Volta Grande reservoir, MG, Brazil. The relation between the parasitosis with rainfall and water quality (pH, electric conductivity, oxygen, chlorophyll, transparency and temperature) is discussed. Prevalence of Proteocephalus macrophallus (Diesing, 1850) and/or P. microscopicus (Woodland, 1935) was 83.3%, mean intensity 110.8 and mean abundance 100.7 during the period. A hundred percent prevalence was reported in August and December 1999, April and December 2000 and June 2001. The largest mean intensities of 122.7 (October 1999), 158.8 (December 1999), 96.4 (February 2000), 400.7 (April 2000), 215.6 (October 2000) and 136.4 (December 2000) were observed. Abiotic factors may favour the development of the species of the food chain that sustain the organisms in the diet of "tucunaré", but in this case, there was no correlation (P > 0.05) between the values of prevalence, mean intensity and mean abundance with the rainfall and water quality. At the same time, these organisms may constitute the intermediate hosts of cestodes. The time-course between the fish species development and the parasitosis manifestation in the definitive host can explain the lack of correlation between the parasitological indexes and abiotic factors. The predation on small fishes and cannibalism described for "tucunaré" might explain the high values of prevalence and intensity of infection. The results are also related to the exotic condition of the host in the reservoir

Effects of the flood regime on the body condition of fish of different trophic guilds in the Upper Paraná River floodplain, Brazil

In this study, we evaluated the influence of various hydrological cycles on the feeding body condition of fish species of different trophic guilds in the Paraná River floodplain, as well as the impacts of upstream impoundments on fish conditions. Attributes of the river floods (duration, time of year, intensity, and variability in a given year) and the body condition, measured by the mean residuals of length-weight ratios, of the detritivorous, herbivorous, insectivorous, invertivores, omnivorous, piscivorous, and planktivorous species were evaluated. Fish were sampled during a period before (1986-1994) and after (2000-2004) the completion of filling of the Porto Primavera Reservoir, which is located upstream from the floodplain area under study. Three sub-basins in the floodplain were sampled: the Ivinheima River, which has no dams; the Paraná River, which has several dams; and the Baia River, which is influenced by the Paraná. A two-way ANOVA identified significant variations in mean body conditions for localities and for the hydrological cycles, and the interactions were also significant. The findings revealed that before the Porto Primavera Reservoir was filled, the body condition of the feeding guilds varied similarly in the three sub basins, but this pattern was not observed after filling was completed. However, in years with minor or no floods, the body condition was high, especially in the sub-basins influenced by Porto Primavera (Paraná and Baía). Pearson's and Spearman's correlations showed that most effects of the floods were unfavorable to the body condition of the guilds, except for the annual variation in water level, which aids herbivores in accessing allochthonous food resources. Detritivores were negatively affected by all flood attributes. A correlation between the relative stomach weight (mean residual of the ratio of total and stomach weights) and the body condition demonstrated the poor relationship between the amount of food intake and weight gain; insectivores were the exception, showing a significant negative correlation. Therefore, for this guild, there is evidence that their food sources during floods have low nutritional value. It is hypothesized that dry years lead to improvement in the nutritional quality of food resources, and that the water released from the upstream dam dilutes and removes these resources without providing new food inputs. This exacerbates the effects of floods on body conditions
