Estados emocionais em professores recém-formados: análise contextual

In general, the early career is a period marked by crises. Hubermam (1992) points out that this period is considered by the teacher as one of life's most difficult professional teaching. According to Machado (2004), the physical education worked only in competitive perspective in school, does not contribute to the school to perform its social role. This approach encourages the use of stigmas, labels and prejudices, so common in school, that marginalize even more students from lower classes, and can make the sport of high performance within the school walls create students with low self-esteem and low motivation within other possible disorders . Thus, this study presents the fundamental importance to aid and support to novice teachers, so that they can understand, and address key emotional aspects that interfere in their practice. Thus, our aim was to identify the most recurrent emotional processes in novice teachers identify and also how these emotional states can influence the professional and personal attitudes of these teachers. Through a bibliographic we seek statements, reports and case studies that provide enough material to our analysis and interpretation in order to collaborate with the study area and proceed to proposals that are not unreasonable or tied to the current system. Among the emotional states reported in the literature, we highlight the main, more present and influent in the beginner teacher as listed as follow: Anxiety, Stress, Fear, Shame, Low Self Confidence and Motivation. Considering these states, Damasio (1996) reports that the United Emotional directly influenced the style and efficiency of cognitive processes, in other words, interfere with the performance of teachers in the teaching front. Thus, Machado (2006) points out that the teacher should have a set of techniques and procedures that drive their practice in a manner appropriate to the leading group. Therefore, the knowledge of Psychology of Physical...

Educação: transformação ou reprodução

Among the various school functions in capitalist society there in the literature and common sense that the school would have a central role in correcting social inequalities produced by the capitalist mode of production. We see, in today's society, children and young people who moved by the desire to get out of where they are, usually on the outskirts, in a vulnerable situation, seek growth through the study; They see it as a way out to another reality with more opportunit ies and chances for improvement, both as regards their quality of life, and even want to change, change and influence their own reality or part of it, with the knowledge learned in school. On the other hand, there are theorists who maintain that the school reproduces the basic features of the social structure and the current system of power in society. Our goal is to discuss the transformative potential of education as opposed to its role of reproduction of social inequalities, through the essential role of the teacher, who has a high profile role when it comes to change. The teacher is one of the first professionals that we remember when we turn to the school and refer to the systematic teaching. But sometimes forms of education present in the school, afflicting much of children and young people and are characterized in order to favor certain classes and eventually stop the growth and development of those who do not meet the required standards. In this paper we intend to compare two lines of thought, alluding to pedagogical activities in class, the Paulo Freire, which brings the teacher's figure with a responsible actor for lead students to reflection of their practice; and Pierre Bourdieu, which considers the pedagogical practice as an act of imposition of values of the ruling class. The work will address the issue from literature

Mid- to late-Holocene paleoceanographic changes on the southeastern Brazilian shelf based on grain size records

; High-resolution grain size analyses of three AMS (14)C-dated cores from the Southeastern Brazilian shelf provide a detailed record of mid- to late-Holocene environmental changes in the Southwestern Atlantic Margin. The cores exhibit millennial variability that we associate with the previously described southward shift of the Inter Tropical Convergence Zone (ITCZ) average latitudinal position over the South American continent during the Holocene climatic maximum. This generated changes in the wind-driven current system of the SW Atlantic margin and modified the grain size characteristics of the sediments deposited there. Centennial variations in the grain size are associated with a previously described late-Holocene enhancement of the El Nino-Southern Oscillation (ENSO) amplitude, which led to stronger NNE trade winds off eastern Brazil, favouring SW transport of sediments from the Paraiba do Sul River. This is recorded in a core from off Cabo Frio as a coarsening trend from 3000 cal. BP onwards. The ENSO enhancement also caused changes in precipitation and wind pattern in southern Brazil, allowing high discharge events and northward extensions of the low-saline water plume from Rio de la Plata. We propose that this resulted in a net increase in northward alongshore transport of fine sediments, seen as a prominent fine-shift at 2000 cal. BP in a core from similar to 24 degrees S on the Brazilian shelf. Wavelet-and spectral analysis of the sortable silt records show a significant similar to 1000-yr periodicity, which we attribute to solar forcing. If correct, this is one of the first indications of solar forcing of this timescale on the Southwestern Atlantic margin.

Patent Strategies and R&D in Complex Product Industries

The study aims at providing a framework conceptualizing patenting activities under the condition of intellectual property rights fragmentation. Such a framework has to deal with the interrelated problems of technological complexity in the modern patent landscape. In that respect, ex-post licensing agreements have been incorporated into the analysis. More precisely, by consolidating the right to use patents required for commercialization of a product, private market solutions, such as cross-licensing agreements and patent pools help firms to overcome problems triggered by the intellectual property rights fragmentation. Thereby, private bargaining between parties as such cannot be isolated from the legal framework. A result of this analysis is that policies ignoring market solutions and only focusing on static gains can mitigate the dynamic efficiency gains as induced by the patent system. The evidence found in this thesis supports the opinion that legal reforms that aim to decrease the degree of patent protection or to lift it all together can hamper the functioning of the current system.

Essays on the Axiomatic Theory of Matching

This dissertation mimics the Turkish college admission procedure. It started with the purpose to reduce the inefficiencies in Turkish market. For this purpose, we propose a mechanism under a new market structure; as we prefer to call, semi-centralization. In chapter 1, we give a brief summary of Matching Theory. We present the first examples in Matching history with the most general papers and mechanisms. In chapter 2, we propose our mechanism. In real life application, that is in Turkish university placements, the mechanism reduces the inefficiencies of the current system. The success of the mechanism depends on the preference profile. It is easy to show that under complete information the mechanism implements the full set of stable matchings for a given profile. In chapter 3, we refine our basic mechanism. The modification on the mechanism has a crucial effect on the results. The new mechanism is, as we call, a middle mechanism. In one of the subdomain, this mechanism coincides with the original basic mechanism. But, in the other partition, it gives the same results with Gale and Shapley's algorithm. In chapter 4, we apply our basic mechanism to well known Roommate Problem. Since the roommate problem is in one-sided game patern, firstly we propose an auxiliary function to convert the game semi centralized two-sided game, because our basic mechanism is designed for this framework. We show that this process is succesful in finding a stable matching in the existence of stability. We also show that our mechanism easily and simply tells us if a profile lacks of stability by using purified orderings. Finally, we show a method to find all the stable matching in the existence of multi stability. The method is simply to run the mechanism for all of the top agents in the social preference.

Iva e Pubblica Autorità: coerenza del sistema e dimensioni nazionali

Il sistema comune europeo dell’imposta sul valore aggiunto privilegia caratteri e finalità economiche nel definire chi siano gli operatori economici soggetti all’IVA. Una disciplina particolare è, tuttavia, prevista per i soggetti di diritto pubblico che, oltre alla principale attività istituzionale, esercitano un’attività di carattere economico. Ai sensi dell’articolo 13 della Direttiva del 28 novembre 2006, 2006/112/CE, gli Stati, le Regioni, le Province, i Comuni e gli altri enti di diritto pubblico, in relazione alle attività ed operazioni che essi effettuano in quanto pubbliche autorità, non sono considerati soggetti passivi IVA anche se in relazione ad esse percepiscono diritti, canoni, contributi o retribuzioni. La vigente disciplina europea delle attività economiche esercitate dagli enti pubblici, oltre che inadeguata al contesto economico attuale, rischia di diventare un fattore che influenza negativamente l’efficacia del modello impositivo dell’IVA e l’agire degli enti pubblici. La tesi propone un modello alternativo che prevede l’inversione dell’impostazione attuale della Direttiva IVA al fine di considerare, di regola, soggetti passivi IVA gli organismi pubblici che svolgono - ancorché nella veste di pubblica autorità - attività oggettivamente economiche.

Genetic patterns in recovered specimens of Caretta caretta from the Adriatic Sea

The Adriatic Sea is considered a feeding and developmental area for Mediterranean loggerhead turtles, but this area is severely threatened by human impacts. In the Adriatic Sea loggerhead turtles are often found stranded or floating, but they are also recovered as by-catch from fishing activities. Nevertheless, information about population structuring and origin of individuals found in the Adriatic Sea are still limited. Cooperation with fishermen and a good network of voluntary collaborators are essential for understanding their distribution, ecology and for developing conservation strategies in the Adriatic Sea. In this study, a comparative analysis of biometric data and DNA sequence polymorphism of the long fragment of the mitochondrial control region was carried out on ninety-three loggerheads recovered from three feeding areas in the Adriatic Sea: North-western, North-eastern and South Adriatic. Differences in turtles body sizes (e.g. Straight Carapace Length) among the three recovery areas and relationship between SCL and the type of recovery were investigated. The origin of turtles from Mediterranean rookeries and the use of the Adriatic feeding habitats by loggerheads in different life-stages were assessed to understand the migratory pathway of the species. The analysis of biometric data revealed a significant difference in turtle sizes between the Southern and the Northern Adriatic. Moreover, size of captured turtles resulted significantly different from the size of stranded and floating individuals. Actually, neritic sub-adults and adults are more affected by incidental captures than juveniles because of their feeding behavior. The Bayesian mixed-stock analysis showed a strong genetic relationship between the Adriatic aggregates and Mediterranean rookeries, while a low pro¬portion of individuals of Atlantic origin were detected in the Adriatic feeding grounds. The presence of migratory pathways towards the Adriatic Sea due to the surface current system was reinforced by the finding of individuals bearing haplotypes endemic to the nesting populations of Libya, Greece and Israel. A relatively high contribution from Turkey and Cyprus to the Northwest and South Adriatic populations was identified when the three sampled areas were analyzed independently. These results have to be taken in account in a conservative perspective, since coastal hazards, affecting the population of turtles feeding in the Adriatic Sea may also affect the nesting populations of the Eastern Mediterranean with a unique genetic pattern.

Spatial and functional relationships between air conduits and blood capillaries in the pulmonary gas exchange tissue of adult and developing chickens

The documented data regarding the three-dimensional structure of the air capillaries (ACs), the ultimate sites of gas exchange in the avian lung is contradictory. Further, the mode of gas exchange, described as cross-current has not been clearly elucidated. We studied the temporal and spatial arrangement of the terminal air conduits of the chicken lung and their relationship with the blood capillaries (BCs) in embryos as well as the definitive architecture in adults. Several visualization techniques that included corrosion casting, light microscopy as well as scanning and transmission electron microscopy were used. Two to six infundibulae extend from each atrium and give rise to numerous ACs that spread centrifugally. Majority of the ACs are tubular structures that give off branches, which anastomose with their neighboring cognates. Some ACs have globular shapes and a few are blind-ending tapering tubes. During inauguration, the luminal aspects of the ACs are characterized by numerous microvillus-like microplicae, which are formed during the complex processes of cell attenuation and canalization of the ACs. The parabronchial exchange BCs, initially inaugurated as disorganized meshworks, are reoriented via pillar formation to lie predominantly orthogonal to the long axes of the ACs. The remodeling of the retiform meshworks by intussusceptive angiogenesis essentially accomplishes a cross-current system at the gas exchange interface in the adults, where BCs form ring-like patterns around the ACs, thus establishing a cross-current system. Our findings clarify the mode of gas exchange in the parabronchial mantle and illuminate the basis for the functional efficiency of the avian lung.

Die Auswirkungen der E-Commerce-Regelungen der EU-Richtlinie über Verbraucherrechte auf das BGB

This article investigates the effect of the Consumer Rights Directive 2011/83/EU on the German BGB. Special emphasis is placed on e-com- merce-relevant legislation. The article is based on the argument that European law requires the German legislator, when it transposes Directives intended to create rights for individuals into the BGB, to do so inbest conformity with the BGB’s current system. It therefore browses through the BGB’s relevant norms and investigates how such a transposition may be achieved. It will conclude that such a transposition is possible, but that the German legislator should de- vote more time to investigate how such transposi- tion shall be acquired.

Das Verhältnis zwischen Urheberrecht und Wissenschaft: Auf die Perspektive kommt es an!

Since the advent of digital network technologies, copyright has become a highly contentious political matter. This is also true in the area of scientific works and the scholarly communication system in general. However, whether the relationship between copyright and scholarship is considered problematic and which, if any, alternative approaches to the current system are preferred, depends upon the perspective. In that regard, the article distinguishes a copyright perspective from a perspective that takes as its starting point the philosophy and sociology of science. The article shows that only the latter, scientific perspective is capable of explaining and adequately regulating the current, fundamental change taking place in the scholarly communication system.
