Published: May 2016

The article dealt with the assessment of somatic changes of the students at the Slovak University of Technology (STU), Faculty of Mechanical Engineering (FME), specifically expressed by Body Mass Index (BMI) and Waist Hip Ratio (WHR) during the years 2007 and 2013. In total 2228 men were involved in the study and measured upon their entry at the university. It was found out that the values of BMI belonged to the category of average range measured for adults (from 22.96 kg.m-2 to 24.60 kg.m-2) and indicates standard values. Statistically significant differences (p<0.01) were discovered between the years 2011 (23.70 kg.m-2) and 2012 (24.60 kg.m-2), 2012 (24.60 kg.m-2) and 2013 (22.96 kg.m-2). In 2012 participants achieved in average the highest values (BMI = 24.60 kg.m-2), which borders with a moderate overweight. In the contrary, in 2013 the students achieved the lowest values of BMI (22.96 kg.m-2). A slight increase of average BMI values may be observed from the first test in 2007 until 2012. The predominance of standard weight was measured at 71% of the total number of monitored students and the predominance of overweight was measured at 22% of students from the total number of university students. The observation of WHR numbers makes us conclude that during our seven year study no significant differences were discovered in the first five years. The values were stable and from the mean point of view, they do not indicate the risk of development of diseases relating to overweight and obesity. In 2012 and 2013 a slight decrease of WHR values was detected < 0.85. Statistically significant differences (p<0.05) were discovered between the years 2010 (0.854) and 2011 (0.864), and also between 2011 (0.864) and 2012 (0.843). The lowest mean value of WHR was measured when performing the last test in the year 2013 (0.823). There was a statistically significant difference at p<0.05 within the years 2012 and 2013. The highest mean value was discovered in 2011 (0.864). However, the average values achieved in a group of students were lower than 1.0, which can be evaluated as a set with no risk of obesity and overweight disease development.

Authors: Žiška Peter , Olasz Dávid , Krčmár Matúš
Published: May 2016

In the study, we have tried to demonstrate the effect of endurance training on changes in functional parameters during the preparation phase (12-week mesocycle) among cross-country skiers. The group consisted of 10 male cross-country skiers (age: 21.4 ±5 year) who completed control (1st 6 week mesocycle) and experimental period (2nd 6 week mesocycle).We focused on the following time-varying parameters: changes in maximal oxygen uptake (VO2max), the level of aerobic (AeT) and anaerobic thresholds (AT), maximum heart rate (HRmax) and performance on the running treadmill. The intra-individual monitoring of each athlete revealed statistical significance of VO2max (mid_VO2max = 69.48 ± 5.72 l.kg-1.min-1, post_ VO2max = 70.96 ± 5.67 ml.kg-1.min-1; p≤0.05) and the level of AT (mid_AT = 86.2 ± 5.43 %, post_AT = 87.8 ± 5.59 %; p≤0.01) the performance on the running treadmill (mid_t = 14:54 ± 1:43 min., post_t = 15:30 ± 1:50 min.; p≤0.05).The significant changes were recorded in the AeT(pre_AeT = 70.3 ± 7.56 %, mid_AeT = 72.5 ± 7.59 %; p≤0.05) in theHRmax(pre_HRmax = 190 ± 8.04 bpm, mid_HRmax = 189 bpm, post_HRmax = 188 ± 7.34 bpm; p = n.s.) during control period. We assume that the significant differences occurred as a result of adaptation changes due to training stimuli, which were induced by changes in functional parameters. Increased training volume in zone lower level of oxygen regime (A1), upper level of oxygen regime (A2) and upper level of lactate tolerance(T2) during experimental period elicited changes which reflected the increase functional parameters and performance on the running treadmill compared to that of control period.
Strontium and Barium in the Triassic Limestone of the Opole Silesia Deposits
Authors: Stanienda Katarzyna
Published: May 2016

This article presents the results of studies of strontium and barium content in Triassic (Muschelkalk) carbonate rock samples taken from the area of the Polish part of the Germanic Basin (the area of Opole Silesia). Sr and Ba were determined in the rocks of all formations of the Lower Muschelkalk - Gogolin Beds, Górażdże Beds, Dziewkowice (Terebratula) Beds and Karchowice Beds. Strontium and barium are chemical elements characteristic for aragonite carbonate phase. Aragonite is unstable calcium carbonate phase which is transformed such as high-Mg calcite into low magnesium calcite during diagenesis. So as Sr and Ba indicate the presence of aragonite in the primary carbonate material. Now these elements concentrate in low-Mg calcite crystal structure. The Triassic rocks of Lower Muschelkalk which are mined in different quarries of the Opole Silesia area are mainly built of low-Mg calcite with lower amounts of high-Mg calcite, protodolomite, ordered dolomite and huntite. There are smaller addition of non-carbonate minerals - quartz, chalcedony, muscovite, feldspars and iron minerals. The presence of Sr and Ba now bound in a structure of low-Mg calcite will indicate the occurrence of aragonite in the primary carbonate material. The Triassic rocks from the area of Opole Silesia were studied to determine the rocks enriched in Sr and Ba. Selected rock samples were examined using ICP AES spectrometry, XRF analysis and microprobe measurements. The results of studies show that strontium and barium occur in rocks of all Lower Muschelkalk formations. The lowest contents of these elements were determined in rocks of Gogolin Beds, higher - in rocks of other formations. The results of studies show that Sr and Ba concentrate in low-Mg calcite which dominates in Lower Muschelkalk rocks. Limestone built mainly of low-Mg calcite or “pure” calcite without substitution of other elements, especially Mg, Fe, Si and Al could be applied in lime industry or in other branches of industry, where pure quality raw material, without substitutions is needed.

How to assess quality of life. Theoretical and methodological research aspects in cross-border regions
Authors: Angelovič Martin , Ištok Robert
Published: May 2016

In our paper we deal with both the theoretical and methodological aspects of our research, which focuses on the quality of life in cross-border regions. The aim of the paper is to draw on the methodological system for assessment of the quality of life in those regions, taking into consideration both the objective and subjective dimension. The first part of the paper contains the use of qualitative methods when assessing the quality of life, which, in our understanding, are not sufficiently applied in the process of assessment of quality, not only in the field of Geography. We also focus on the definition of the key terms related to our work, such as ‘quality of life, border and border-region/neighbour’. The main emphasis of our work lies in the formulation of the theoretical and methodological model of the quality of life assessment in the cross-border regions. The methodological outline of researching this issue is presented in the chart. The scale of the region is a key element we take into consideration, since it is significant when choosing the appropriate method of life quality assessment. We also distinguish between the application of both the qualitative and quantitative research methods on various scales. In our opinion, the representation of the qualitative methods in research should increase with the increase in the scale of the area researched. In the conclusion we provide selected outcomes of our research at various scales, which confirm the validity of our theoretical basis, since we came to various findings, depending on the scales researched.
Demographic development of Zachodniopomorskie voivodship in the years 2000-2012 in the light of transportation network accessibility
Authors: Chądzyńska Elżbieta
Published: May 2016

The area of Zachodniopomorskie voivodship is characterized by specific features, resulting from its position in space. The location of the regional capital Szczecin at the mouth of the River Odra and near the Polish-German border, in the close vicinity of well-developed Nordic countries, and on the outskirts of the region creates special conditions for development. At the same time, the considerable remoteness of most small towns from the capital region and the inadequate network of connections in a natural North-South direction make it difficult to work with the assets of larger centres of development like Szczecin and Koszalin. The present approach is based on Webb’s typology for the gminas of Zachodniopomorskie voivodship compared with the analysis of the characteristics of the transportation network. Traffic volume of real transportation network was simulated by using a model based on the idea of intervening opportunities. Two categories of movements were analysed: movements to work and, due to the specificity of the region, tourists’ movements.
‘Close to the city centre, close to the university’. Are there symptoms of studentification in Gdańsk, Poland?
Authors: Grabkowska Maja , Frankowski Jan
Published: May 2016

Students are increasingly recognised as important actors of urban change in contemporary cities. The article presents an analysis of incipient studentification processes in Gdańsk. Its general aim is to reveal patterns of students’ presence and activity which translate into spatial and socio-economic transformations of a post-socialist city at the level of neighbourhoods. The study consists of a survey on students’ residential behaviour, complemented by field and desk research. According to the results, due to the fact that Polish students’ housing and lifestyle choices are limited by their low purchasing power, student-dedicated services have a rather negative impact on the quality of urban space. Furthermore, under these conditions studentification may not be regarded as a stimulus to the gentrification process, which is rather driven by hipsters and affluent foreign students.
De Facto States and Democracy: The Case of Abkhazia
Authors: Kopeček Vincenc , Hoch Tomáš , Baar Vladimír
Published: May 2016

De-facto states constitute an interesting and important anomaly in the international system of sovereign states. No matter how successful and efficient in the administration of their territories they are, they fail to achieve international recognition. In the past, their claims for independence were based primarily on the right to national self-determination, historical continuity and claim for a remedial right to secession, based on alleged human-rights violations. Since 2005, official representatives of several de facto states have repeatedly emphasised the importance of democracy promotion in their political entities. A possible explanation of this phenomenon dwells in the belief that those states which have demonstrated their economic viability and promote the organization of a democratic state should gain their sovereignty. This article demonstrates the so called “democracy-for-recognition strategy” in the case study of Abkhazia. On the basis of the field research in Abkhazia we identify factors that promote, as well as those that obstruct the democratisation process in the country.
Bojkovice: Transformation of a peripheral micro-region at the Czech-Slovak border
Authors: Vaishar Antonín , Šťastná Milada
Published: May 2016

The paper analyses the problem of a rural region in the peripheral position. Bojkovice micro-region on the Czech (Moravian)-Slovak border has been chosen as a case study. Economic transformation of productive and non-productive branches, demographic development (depopulation and aging) and networking in the area were characterized by using statistical data and field research. Development, understood as improvement in quality of life and not in sense of quantitative growth, is highlighted with regard to the changing perception of the countryside. The question remains: how to use peripherality for prosperity? Peripheral countryside is known as “the right countryside” in comparison to suburbanized and globalized countryside in core regions. Based on the research, production embedded in local sources and traditions, ecological agriculture using the protection of landscape and soft tourism are proposed as solutions. Networking like the association of municipalities, LEADER local action group or White Carpathian Euroregion could be the instruments of micro-regional collaboration. The human and social factors seem to be more important than objective conditions. Long-term population stability is the main advantage. However, a lower level of formal education could be a problem. The character of social capital is considered as a decisive circumstance - whether it is passive social capital resistant to outer innovations or active social capital open for now ideas.
Changing Role of Indian Woman: A Glimpse into Two Bollywood Movies English – Vinglish and Queen
Authors: Bhaumik Mahuya
Published: May 2016

Bollywood, being one of the biggest film industries of India, is an interesting area of research to understand the socio-cultural perspectives of today’s India. My paper will focus on the changing role of Indian woman. It will argue if the change is merely superficial or the Indian woman has been successful to negotiate with and challenge the patriarchal social structure. These multiple issues will be discussed with special reference to two of the latest Bollywood movies, namely, English-Vinglish and Queen.

The focus on these two movies is because both concentrate on emancipation of woman. Sashi, the central character of English-Vinglish, despite facing all kinds of humiliation in her own family and finally learning English (her inability to speak in English being one of the primary reasons for her being ridiculed in her family) comes back to her family at the end. Queen showcases a different kind of emancipation where Rani, the leading lady of the movie, being dumped by her fiancé, decides to go for her honeymoon trip all by herself and recognises herself anew.

These two movies are examples of the changing role of woman who does not need a male to rescue her from danger or to console her in her tears. She is a self-sufficient woman who does not forget her roots. Both the movies generate thought-provoking questions about the status of woman in present India and can be employed as lenses to see through the multiple layers of the gendered Indian society.

Published: May 2016

Gestational diabetes mellitus (GDM) is defined as a glucose intolerance that occurs for the first time or it is first identified during pregnancy. The GDM etiology is multifactorial. It has not completely been established yet and several known risk factors may contribute to its onset. To date, there are no shared guidelines on the management and follow-up, especially regarding the low-income countries. In this paper, we describe the state of art about epidemiology, physiopathology, diagnosis, and management of GDM. Moreover, we focus on the current state in low income countries trying to outline basis for further research.

Intubation-Surfactant: Extubation on Continuous Positive Pressure Ventilation. Who Are the Best Candidates?
Authors: Ognean Maria Livia , Stoicescu Silvia-Maria , Boantă Oana , Năstase Leonard , Gliga Carmen , Cucerea Manuela
Published: May 2016

Introduction: Respiratory distress syndrome (RDS) continues to be the leading cause of illness and death in preterm infants. Studies indicate that INSURE strategy (INtubate-SURfactant administration and Extubate to nasal continuous positive airway pressure [nCPAP]) is better than mechanical ventilation (MV) with rescue surfactant, for the management of respiratory distress syndrome (RDS) in very low birth weight (VLBW) neonates, as it has a synergistic effect on alveolar stability.

Aim of the study: To identify the factors associated with INSURE strategy failure in preterm infants with gestational age (GA) ≤ 32 weeks.

Materials and Methods: This was a retrospective cohort study, based on data collected in the Romanian National Registry for RDS patients by three regional (level III) centers between 01.01.2010 and 31.12.2011. All preterm infants of ≤ 32 weeks GA were included. Prenatal and neonatal information were compared between (Group 1), the preterm infants successfully treated using INtubation-SURfactant-Extubation on nasal CPAP (INSURE) strategy and (Group 2), those who needed mechanical ventilation within seventy two hours after INSURE.

Results: A total of 637 preterm infants with GA ≤ 32 weeks were included in the study. INSURE strategy was performed in fifty seven cases (8.9%) [Group 1] and was successful in thirty one patients (54.4%). No differences were found as regards the studied prenatal and intranatal characteristics between (Group 1) and Group 2 who needed mechanical ventilation. Group 2 preterm infants who needed mechanical ventilation within 72 hours after INSURE had significantly lower mean Apgar scores at 1 and 5 minutes and lower peripheral oxygen saturation (SpO2) during resuscitation at birth (p<0.05). Successful INSURE strategy was associated with greater GA, birth weight (BW), fraction of inspired oxygen (FiO2) during resuscitation, and an increased mean dose of surfactant but these associations were not statistically significant (p>0.5).

Conclusion: In preterm infants ≤ 32 weeks gestation, increased INSURE failure rates are associated with complicated pregnancies, significantly lower Apgar scores at 1 and 5 minutes, and lower peripheral oxygen saturation during resuscitation.

van den Tillaar, R, Vatten, T, and von Heimburg, E. Effects of short or long warm-up on intermediate running performance. J Strength Cond Res 31(1): 37–44, 2017—The aim of the study was to compare the effects of a long warm-up (general + specific) and a short warm-up (specific) on intermediate running performance (3-minute run). Thirteen experienced endurance-trained athletes (age 23.2 ± 2.3 years, body mass 79.8 ± 8.2 kg, body height 1.82 ± 0.05 m) conducted 2 types of warm-ups in a crossover design with 1 week in between: a long warm-up (10 minutes, 80% maximal heart rate, and 8 × 60 m sprint with increasing intensity and 1 minute rest in between) and a short warm-up (8 × 60 m sprint with increasing intensity and 1 minute rest in between). Each warm-up was followed by a 3-minute running test on a nonmotorized treadmill. Total running distance, running velocity at each 30 seconds, heart rate, blood lactate concentration, oxygen uptake, and rate of perceived exertion were measured. No significant differences in running performance variables and physiological parameters were found between the 2 warm-up protocols, except for the rate of perceived exertion and heart rate, which were higher after the long warm-up and after the 3-minute running test compared with the short warm-up. It was concluded that a short warm-up is as effective as a long warm-up for intermediate performance. Therefore, athletes can choose for themselves if they want to include a general part in their warm-up routines, even though it would not enhance their running performance more compared with only using a short, specific warm-up. However, to increase efficiency of time for training or competition, these short, specific warm-ups should be performed instead of long warm-ups.
Age Is Associated with Reduced Sharp-Wave Ripple Frequency and Altered Patterns of Neuronal Variability
Authors: Wiegand Jean-Paul L. , Gray Daniel T. , Schimanski Lesley A. , Lipa Peter , Barnes C. A. , Cowen Stephen L.
Published: May 2016

Spatial and episodic memory performance declines with age, and the neural basis for this decline is not well understood. Sharp-wave ripples are brief (∼70 ms) high-frequency oscillatory events generated in the hippocampus and are associated with the consolidation of spatial memories. Given the connection between ripple oscillations and memory consolidation, we investigated whether the structure of ripple oscillations and ripple-triggered patterns of single-unit activity are altered in aged rats. Local field and single-unit activity surrounding sharp-wave ripple events were examined in the CA1 region of the hippocampus of old (n= 5) and young (n= 6) F344 rats during periods of rest preceding and following performance on a place-dependent eyeblink-conditioning task. Neural responses in aged rats differed from responses in young rats in several ways. First, compared with young rats, the rate of ripple occurrence (ripple density) is reduced in aged rats during postbehavior rest. Second, mean ripple frequency during prebehavior and postbehavior rest is lower in aged animals (aged: 132 Hz; young: 146 Hz). Third, single neurons in aged animals responded more consistently from ripple to ripple. Fourth, variability in interspike intervals was greater in aged rats. Finally, neurons were tuned to a narrower range of phases of the ripple oscillation relative to young animals. Together, these results suggest that the CA1 network in aged animals has a reduced “vocabulary” of available representational states.

SIGNIFICANCE STATEMENTThe hippocampus is a structure that is critical for the formation of episodic memories. Sharp-wave ripple events generated in the hippocampus have been implicated in memory consolidation processes critical to memory stabilization. We examine here whether these ripple oscillations are altered over the course of the life span, which could contribute to hippocampus-dependent memory deficits that occur during aging. This experiment used young and aged memory-impaired rats to examine age-related changes in ripple architecture, ripple-triggered spike variance, and spike-phase coherence. We found that there are, indeed, significant changes in characteristics of ripples in older animals that could impact consolidation processes and memory stabilization in the aged brain.
Molecular determinants of a competent bovine corpus luteum: first- vs final-wave dominant follicles
Authors: Gregson E , Webb R , Sheldrick E L , Campbell B K , Mann G E , Liddell S , Sinclair K D
Published: May 2016

Reproductive management in cattle requires the synchrony of follicle development and oestrus before insemination. However, ovulation of follicles that have not undergone normal physiological maturation can lead to suboptimal luteal function. Here, we investigated the expression of a targeted set of 47 genes in (a) a first-wave vs final-wave dominant follicle (DF; the latter destined to ovulate spontaneously) and (b) 6-day-old corpora lutea (CLs) following either spontaneous ovulation or induced ovulation of a first-wave DF to ascertain their functional significance for competent CL development. Both the mass and progesterone-synthesising capacity of a CL formed following induced ovulation of a first-wave DF were impaired. These impaired CLs had reduced expression of steroidogenic enzymes (e.g. STAR and HSD3B1), luteotrophic receptors (LHCGR) and angiogenic regulators (e.g. VEGFA) and increased expression of BMP2 (linked to luteolysis). Relative to final-wave DFs, characteristic features of first-wave DFs included reduced oestradiol concentrations and a reduced oestradiol:progesterone ratio in the face of increased expression of key steroidogenic enzymes (i.e. CYP11A1, HSD3B1 and CYP19A1) in granulosa cells and reduced expression of the HDL receptor SCARB1 in thecal cells. Transcripts for further components of the TGF and IGF systems (e.g. INHA, INHBA, IGF2R and IGFBP2) varied between the first- and final-wave DFs. These results highlight the importance of hormones such as progesterone interacting with local components of both the TGF and IGF systems to affect the maturation of the ovulatory follicle and functional competency of the subsequent CL.

The paper has analyzed the effect of online learning and traditional mode of learning on students’ engagement in learning. A sample of 50 students studying psychology in their B.A course was selected randomly from one college in Chandigarh. An online learning course in selected topics of psychology was developed. The experimental group of the study was exposed through online learning mode for 15 days. Likewise, control group was taught the same content by traditional learning for 15 days as well. Both the groups were controlled on same instructional design model such as ADDIE (analysis, design, development, implementation and evaluation), same number of participants, same content was employed for teaching and they were both matched on pre-test of engagement in learning. The students’ post-test scores on engagement in learning was analyzed using t-test to determine if there were significant differences between the two groups. Results indicated significant differences between online learning and traditional learning on students’ engagement in learning as students taught by online learning were more engaged in learning than students who were taught by traditional learning. It indicates that learning through online does enhance students’ engagement in learning.

Microvolt T-wave alternans (TWA), characterised as beat-to-beat fluctuation of T-wave amplitude and morphology, is an electrophysiological phenomenon associated clinically with impending ventricular arrhythmias and is an important marker of arrhythmia risk. Currently, two main methods for the detection of TWA exist, namely, the spectral method and the time-domain modified moving average method; both are discussed in this review. Microvolt TWA has been associated with cardiovascular mortality and sudden cardiac death in several clinical studies involving >14,000 subjects with reduced as well as preserved left ventricular function. Although TWA appears to be a useful marker of susceptibility for lethal ventricular arrhythmias and cardiovascular death, so far there is no sufficient evidence from randomised clinical trials to support its use in guiding therapy. However, several ongoing trials are expected to provide more information about the clinical use of TWA testing.

The incidence of infection following implantation of cardiac implantable electronic devices (CIEDs) is increasing at a faster rate than that of device implantation. Patients with a CIED infection usually require hospitalisation and complete device and lead removal. A significant proportion die from their infection. Transvenous lead extraction (TLE) is associated with rare but serious complications including major vascular injury or cardiac perforation. Operator experience and advances in lead extraction methods, including laser technology and rotational sheaths, have resulted in procedures having a low risk of complication and mortality. Strategies for preventing CIED infections include intravenous antibiotics and aseptic surgical techniques. An additional method to reduce CIED infection may be the use of antibacterial TYRX™ envelope. Data from non-randomised cohort studies have indicated that antibacterial envelope use can reduce the incidence of CIED infection by more than 80 % in high-risk patients and a randomised clinical trial is ongoing.

Published: May 2016

ABSTRACT The sunflower plant is an oilseed crop that has aroused a great interest in the Brazilian and international scenery especillay because of the possibility of using its oil for biodiesel production. The objective of this study was to evaluate productivity and yield components of Embrapa 122 sunflower according to the spatial arrangement. Treatments were arranged in 4 x 4 factorial arrangement, which are the four spacings between rows (0.30; 0.50; 0.70 and 0.90 m) and four sowing densities (30,000; 45,000; 60,000 and 75,000 plants ha-1). The experiment was carried out in a complete randomized block design with four replications. The experiments were conducted in the experimental area of the Plant Science Department in Fortaleza, State of Ceará-Brazil and on the Curu Vale Experimental Farm in Pentecoste, State of Ceará-Brazil. Productivity and the following production components were analyzed in the end of the crop cycle: harvested capitula, capitulum diameter, capitulum mass, achene mass per capitulum, mass of 100 achenes, achenes per capitulum, harvest index and oil content in the achenes. The experiments were analyzed jointly in relation to the cropping area and the data submitted to analysis of variance and quantitative factors tested by polynomial regression. The variables, spacing, density and cropping area did not interact with these variables and the spatial arrangement of the plants affected only the components. The cropping area influences the productive behavior of sunflower Embrapa 122. The spatial arrangement of the plants of sunflower of variety Embrapa 122 influences yield components but does not affect productivity.

RESUMO Objetivou-se, com este trabalho, avaliar o desempenho do consórcio de milho com capim tifton na Amazônia sul ocidental. O delineamento experimental utilizado foi em blocos casualizados, com seis tratamentos e quatro repetições. Os tratamentos foram constituídos pelos monocultivos de milho e de capim tifton e por quatro épocas de transplantio de capim tifton nas entrelinhas de semeadura do milho (SM), sendo: simultâneo, aos 15, 30 e 45 dias após a SM. Para o milho, avaliaram-se: biomassa de 100 grãos, número de fileiras de grãos por espiga, produtividade de grãos, altura da planta e inserção da primeira espiga. A biomassa seca do capim tifton foi estimada a partir de dois cortes, com intervalo de 20 dias entre a primeira e a segunda coleta. Para avaliar a eficiência dos consórcios em relação aos monocultivos, utilizou-se o índice de equivalência de área. Os resultados obtidos foram submetidos ao teste de Shapiro-Wilk (p<0,05), a fim de aferir a normalidade dos dados, seguido pela análise de variância. Foram ajustados modelos de regressão para as épocas de implantação do capim tifton nas entrelinhas do milho, quando houve efeito significativo pelo teste F, a 5% de probabilidade. Utilizou-se o teste de Dunnet (p ≤ 0,05) para as comparações entre o milho consorciado com tifton e os monocultivos (testemunha). O milho não sofre interferência quando consorciado com capim tifton. Entretanto, o tifton apresenta menor acúmulo de biomassa seca quando consorciado com o milho. O melhor desempenho do consórcio verificou-se na implantação simultânea do milho com capim tifton.
A SKETCH ON NĀGĀRJUNA'S PERSPECTIVES ON "RELATION"
Authors: Toso Krishna Del
Published: May 2016

ABSTRACT The aim of this paper is to provide a sketch on the way Nāgārjuna deals with the idea of 'relation'. The concept of 'relation' as expressed in the Pāli sources is here theoretically systematized according to three patterns: 1. (onto)logical, 2. strictly subordinative existential, 3. non-strictly subordinative existential. After having discussed Nāgārjuna's acceptance and treatment of these three patterns, particular attention is paid to the non-strictly subordinative existential relation. This kind of relation is meant to describe the way the factors of the conditioned co-origination are linked to each other and is exemplified by Nāgārjuna by means of the father-son bond. A possible way to explain the conditioned co-origination doctrine in the light of the father-son example is here suggested by having resource to the 'Cambridge change' theory. Even if in the Pāli Canon the non-strictly subordinative existential pattern is said to apply to all the other factors of the conditioned co-origination, there is no direct evidence that it concerns also the avidyā-saṃskāras link. It will be shown how Nāgārjuna, by applying it to the avidyā-saṃskāras link, seems to introduce a new perspective in the conditioned co-origination theory.
A comparabilidade das escolhas contábeis na mensuração subsequente de ativos imobilizados, de ativos intangíveis e de propriedades para investimento em empresas da América do Sul
Authors: Souza Flaida Êmine Alves de , Lemes Sirlei
Published: May 2016

A expertise em comparabilidade, escolhas contábeis e valor justo é um dos temas mais controvertidos e carentes de discussão no cenário contábil atual. As escolhas contábeis são necessárias para que seja garantida a representação fidedigna, ao mesmo tempo que seu uso discricionário pode diminuir a comparabilidade esperada pelo International Accounting Standards Board (IASB). Neste artigo, identificou-se o grau de comparabilidade das escolhas contábeis na mensuração subsequente de ativos imobilizados, de ativos intangíveis e de propriedades para investimento (PPI) de companhias abertas do Brasil, Chile e Peru, além de averiguar se determinadas características das entidades podem influenciar a escolha dos gestores pelo valor justo. A comparabilidade foi medida por meio do índice T e a identificação das variáveis explicativas foi feita por meio de regressões, no período 2009-2013. Constatou-se que, para os ativos imobilizados, as comparabilidades nacional e internacional aumentaram com a adoção das IFRS, sendo crescentes ao longo do tempo. Para os ativos intangíveis, não houve aumento substancial nas comparabilidades nacional e internacional. Para as PPI, as comparabilidades nacional e internacional não aumentaram com a adoção das IFRS, permanecendo com índices próximos a 0,50 (comparabilidade baixa) em praticamente todos os anos. Assim, a simples adoção das IFRS não garantiu a comparabilidade. Por meio da análise de regressão, identificou-se que as características setor de atuação, auditoria por big four, país, remuneração dos gestores, tamanho da entidade, endividamento, rentabilidade, relevância e tempo influenciaram as escolhas contábeis dos gestores, o que indica a possibilidade de ter havido uso das opções investigadas para a prática de gerenciamento de resultados.
Determinantes do Bond Spread e do Credit Default Swap: Por que são diferentes? O caso da Petrobras
Authors: Oliveira Fernando Nascimento de , Pinto Renan Feuchard
Published: May 2016

Neste artigo, estudamos os principais determinantes do risco de crédito da Petrobras, medido por meio dos asset swap spreads (ASW) e dos credit default swaps (CDS), replicando os principais trabalhos sobre o tema e analisando se os dois produtos apreçam risco de forma diferente. Nossos resultados permitem concluir que, curiosamente, variáveis específicas da empresa (microeconômicas) são pouco ou nada significativas para explicar a discrepância entre os mercados, e que grande parte da diferença entre eles (também conhecida como CDS-Bond Basis) pode ser explicada pela resposta de cada produto a variáveis macroeconômicas. A principal contribuição deste artigo é ser o primeiro da literatura que trata do tema do risco de crédito ou liquidez de uma empresa brasileira, sob a ótica dos bond spreads e CDS, negociados no mercado externo, além de discutir por que existe diferença entre eles.

Apontamentos sobre a participação feminina na pesquisa no campo da saúde a partir do acervo de obras raras da Biblioteca de Manguinhos da Fundação Oswaldo Cruz
Authors: Rodrigues Jeorgina Gentil , Guimarães Maria Cristina Soares
Published: May 2016

RESUMO Esse artigo pretende discutir a participação feminina na pesquisa no campo da saúde a partir do acervo de obras raras da Biblioteca de Manguinhos do Icict/Fiocruz, sendo as teses inaugurais o primeiro passo para traçar esse caminho. São ainda raras as análises que deem conta do uso e impacto das teses como fonte de informação para pesquisa. Além, pouco se discute sobre os elementos descritivos dessas teses e suas características bibliográficas e bibliológicas enquanto obras raras, o que tem implicações na descrição e organização das mesmas para disponibilizá-las. Essa é a discussão aqui travada, na expectativa que seja possível dar início a descrição de uma trajetória feminina no campo das ciências da saúde a partir da digitalização do material identificado e disponibilização para a comunidade científica, por meio do Repositório Institucional da Fiocruz, o ARCA.
LINGUAGEM E EDUCAÇÃO: REFLEXÕES ACERCA DAS NOVAS TECNOLOGIAS DA COMUNICAÇÃO
Authors: Adams Adair , Souza Antonio Escandiel de
Published: May 2016

O presente ensaio discute desafios da educação na atualidade marcada pelas novas tecnologias da comunicação e informação (TIC), propondo um caminho de pensamento que não se entrega nem a uma fundamentação e/ou justificação da educação nessas tecnologias e nem a uma proposta que pensa a educação como um meio de qualificação de competências para a organização mercadológica do mundo. Argumenta-se que o centro da educação é um processo de humanização, aqui pensado sob o ponto de vista do paradigma da linguagem hermenêutica, em que é preciso colocar em questão o ser humano, sempre no presente, para que se possa pensar as necessidades e possibilidades da educação, também sempre no presente. Colocar o ser humano em questão é não tomá-lo como dado constituído tecnologicamente, perspectiva difundida na atualidade de que há um novo ser humano, que já é pós-humano e/ou ciborg.
Como a Gestão de Práticas de Oferta de Crédito Impacta a de Estoque
Authors: Carvalho Claudinê Jordão
Published: May 2016

O objetivo deste estudo é analisar o impacto da gestão das práticas de oferta de crédito sobre a de estoques em uma amostra de 432 micro e pequenas empresas. O modelo apoiou-se nas teorias de agência, de custos de transação e da pecking order. Os dados da amostra foram submetidos a técnicas multivariadas, de análise fatorial confirmatória e exploratória, e regressões estruturais simultâneas. A proposição de que a gestão das práticas de crédito determina a gestão de estoques, quando mediada pela gestão de caixa, foi suportada. O estudo dimensionou os reflexos dos efeitos diretos e dos indiretos entre os três construtos latentes.

Authors: Aguiar Júnior Orlando , Saraiva João Filocrc
Published: May 2016

Resumo: Apresentamos, justificamos e fundamentamos um modelo de ensino baseado nas três etapas piagetianas de construção de conhecimentos: aytríades dialéticas que Piaget e colaboradores denominam etapas INTRA, INTER e TRANS. Sugerimos que o modelo pode tornar-se um instrumento auxiliar para a pesquisa e para a prática pedagógica no que se refere ao planejamento didático e à construção de currículos. Finalmente, descrevemos ações e pesquisas que estamos desenvolvendo com o intuito de, por um lado, dar validação empírica ao modelo apresentado e, por outro, aprimorar sua utilização enquanto instrumento de formação continuada de professores.

CHARACTERPATHY, THE POSITION OF THE INDIVIDUAL IN THE FIELD OF JOUISSANCE AND THE STRUGGLE TO BUILD AN ANALYZABLE SYMPTOM
Authors: Marinho Paula Duarte Félix , Luchina Márcia Maria Rosa Vieira
Published: May 2016

RESUMO: Caracteropatia, a posição do sujeito no campo do gozo e as dificuldades na instalação do sintoma como analisável. Ao resgatarmos a noção de caráter em alguns teóricos da psicanálise, localizamos nele um operador teórico-clínico importante para a investigação de manifestações de sofrimento psíquico. O caráter supõe algo mais arcaico do que o sintoma, portanto, anterior ao estágio de formação do sintoma. As caracteropatias, ou patologias do caráter, são formas de apresentação subjetiva nas quais predominam as saídas do sujeito pela via do ato em detrimento da palavra e do sentido. Elas trazem desafios na instalação do sintoma como analisável, devido ao modo de gozo de difícil sintomatização apresentado pelo sujeito. Com isso em vista, abordaremos também algumas contribuições quanto à direção do tratamento nesses casos.
PERVERSE MANIFESTATIONS IN A MELACHOLIC STRUCTURE
Authors: Roggia Larissa Bastiani , Bastos André Goettems
Published: May 2016

ABSTRACT: This study aims to describe the expression of perverse traits operating in a melancholic personality structure. The definition of the basic concepts of structure, organization of personality and character traits is made. The characteristics of the melancholic structure and perverse organization are described and through the study of a single case, we seek to demonstrate the psychodynamics of a melancholic personality structure and identify the manifestation of perverse traits. The clinical discussion focuses on the acting of the perverse traits over melancholy. The paper demonstrates the importance of understanding these dynamics and diagnostic aspects to the clinical practice in psychoanalysis. Furthermore, it was possible to conclude that perverse manifestations may occur in different personality structures, not being exclusive of perverse organizations of the self.
