Controle democrático no capitalismo contemporâneo: limites e contradições

This study examines the determinations of the structural crisis of capital in the democratic control effected on the councils of rights and policies. Therefore the research aimed to apprehend and analyze the conjunctural and structural determinations and cyclical changes that incide on democratic control established by the Federal Constitution of 1988. The specific objectives turned to: (1) identify and analyze the theoretical and political fundamentals of democratic control in the production of social service in ENPESS 2010, in the productions of CFESS and the journal social services and society, (2) apprehend and analyze the possibilities, limits, contradictions and social direction of democratic control in contemporaneity and (3) identify and analyze the major political forces that constitute support and opposition to the exercise of democratic control. To approximate to the intended objectives the way theoretical and methodological covered was based in a perspective of totality that allows the apprehension of the object of study in their contradictory dimensions of universality, particularity and singularity. The results enabled to develop critical analysis of theoretical production of the Brazilian social service on the subject, having as snip studies of the journals social service and society; works of ENPESS 2010 and CFESS positioning. It was found, so in analysis undertaken, the spaces of democratic control suffer inflections of capital that shape their practices and social direction. In theoretical productions chosen, identified the prevalence of democratic control studied under an endogenous perspective to participatory canals, with incipient connections to the structural/conjunctural determinations of a historical period of crisis and seeks to restore the hegemony of capital. The positioning of the CFESS tends to recognition of democratic control in its contradictory dynamics recognizing the limits imposed by the sociability of the capital at the present time

Efeito da estimulação transcraniana por corrente contínua anódica sobre o controle do movimento em para-halterofilistas

Introduction: The sport practiced by people with disabilities has been growing in recent years. Consequently, advances in assessment and training methods have emerged. However, the paralympic sport keeps in tow these advances, with few specific studies that consider disability as intervening factor. The transcranial direct current stimulation (tDCS) is a technique that has proven to be capable of modulating brain function. Studies show beneficial effects of tDCS on muscle strength, power and fatigue during exercise. Objective: Investigate de the effect of tDCS on movement control in para-powerlifters. Methods: Eight subjects underwent two sessions of motion capture, which previously applied the anodic tDCS or sham sessions in the cerebellum. Three movements were performed with increasing load between 90-95% of 1MR. The movements were recorded by an 10 infrared cameras system which reconstructed the 3D trajectory of markers placed on the bar. Results: There have been changes between the anodic and sham conditions over bar level (initial, final, maximum during the eccentric and concentric phase) and in the difference between the final and initial bar level. Moreover, there was difference in bar level (final and during the eccentric phase) comparing athletes amputees and les autres. Conclusion: The findings of this study suggest that tDCS applied prior to the exercise over the cerebellum in para-powerlifters acts differently according to disability

O controle social do judiciário: a experiência do Observatório da Justiça e Cidadania no Estado do Rio Grande do Norte

This dissertation deals with the possibility of build an effective social control of the judiciary Brazilians. The theme was bounded by a cut geographic and secular: the experience of the Center of Justice and Citizenship in the state of Rio Grande do Norte (OJC/RN), which begins formally in august 2003. The research approach and leave of experience in judicial practice and policy specific substrates to theorize about the subject. We collected documents about cases, the judicial diagnoses, reports, news material, in addition to lifting bibliographic. Therefore, it is working with about notions of a democratic state of right in the light of the Brazilian Constitution of 1988, in order to contextualize the insertion of the judicial system, by the prospect of legitimacy, which is considered by a look formal and material. It is a brief analysis of the system of official control of the judiciary (internal and external), is emphasizing its shortcomings functional and its corporate character, which suffers from poor conformation democratic. Then there is a discussion about the need to establish the social control of the judiciary, through the prism of relations of power that are locked in the judiciary, the lack of formal criteria for the guarantee of obtaining the correct judgment (laws, precedents and conscience of the judge), the problems of impunity and justice class, and from the examination of some cases, as the body of search. From this conjuncture, prepares to be an outline of shapes and the limits of social control, consonant the proposal erected in certain sectors of organized civil society, represented by the movement s social OJC. In the end, considerations are made on the legitimacy and constitutionality of OJC

A autonomia da escola pública :um complexo movimento entre a outorga e a construção

The present research to explorer the configurations that come being given to the autonomy of the school, since the decade of 1990. We investigate the implementation of the principle of the autonomy in the public system of education of the State of Pernambuco and, specifically, in four school units and this schools its in the quarters of Stubborn Brasilia Teimosa and Casa Amarela, both located in Recife. We try to know if the implementation of the autonomy of the school is circumscribed in the process of productive reorganization, it was evidenced that the inclusion of this principle in the educational politics - in the scopes national and state - obeyed the dynamics of retraction that, in the neoliberal context, the performance of the State in relation to the public education and the school characterizes, with consequence impact in the investigated schools. From the empirical inquiry it was identified to the occurrence of a movement realized for the social actors of the schools research in direction to the construction of the pertaining to school autonomy; this movement presenting some limits and fragilities. It was evidenced despite this movement varied of intensity in the measure where the social actors of the schools had developed levels of dinamics processes (in greater or minor degree) related with the diverse expressions of democratic management that can occur into the school, such as: elaboration of the Politician-Pedagogical Project, institution and functioning of the Pertaining to school Advice, etc. The set of the carried through analyses made possible that it concluded that, in the context neoliberal and delimited to the investigated time and space, the implementation of the autonomy of the school comes if giving in way to a complex movement of construction

Controle adaptativo robusto para um modelo desacoplado de um robô móvel

This thesis presents a new structure of robust adaptive controller applied to mobile robots (surface mobile robot) with nonholonomic constraints. It acts in the dynamics and kinematics of the robot, and it is split in two distinct parts. The first part controls the robot dynamics, using variable structure model reference adaptive controllers. The second part controls the robot kinematics, using a position controller, whose objective is to make the robot to reach any point in the cartesian plan. The kinematic controller is based only on information about the robot configuration. A decoupling method is adopted to transform the linear model of the mobile robot, a multiple-input multiple-output system, into two decoupled single-input single-output systems, thus reducing the complexity of designing the controller for the mobile robot. After that, a variable structure model reference adaptive controller is applied to each one of the resulting systems. One of such controllers will be responsible for the robot position and the other for the leading angle, using reference signals generated by the position controller. To validate the proposed structure, some simulated and experimental results using differential drive mobile robots of a robot soccer kit are presented. The simulator uses the main characteristics of real physical system as noise and non-linearities such as deadzone and saturation. The experimental results were obtained through an C++ program applied to the robot soccer kit of Microrobot team at the LACI/UFRN. The simulated and experimental results are presented and discussed at the end of the text

Controle de posição com restrição à orientação de um Veículo Aéreo Não-Tripulado tipo Quadrirrotor

Quadrotors aircraft are composed by four propellers mounted on four engines on a cross or x disposition, and, in this structure, the engines on the same arm spin in the same direction and the other arm in the opposite direction. By rotating each helix generates vertical upward thrust. The control is done by varying the rotational speed of each motor. Among the advantages of this type of vehicle can cite the mechanical simplicity of construction, the high degree of maneuverability and the ability to have vertical takeoffs and landings. The modeling and control of quadrirrotores have been a challenge due to problems such as nonlinearity and coupling between variables. Several strategies have been developed to control this type of vehicle, from the classical control to modern. There are air surveillance applications where a camera is fixed on the vehicle to point forward, where it is desired that the quadrotor moves at a fixed altitude toward the target also pointing forward, which imposes an artificial constraint motion, because it is not desired that it moves laterally, but only forwards or backwards and around its axes . This restriction is similar to the naturally existing on robots powered by wheels with differential drive, which also can not move laterally, due to the friction of the wheels. Therefore, a position control strategy similar to that used in this type of robot could be adapted for aerial robots like quadrotor. This dissertation presents and discusses some strategies for the control of position and orientation of quadrotors found in the literature and proposes a strategy based on dynamic control of mobile robots with differential drive, called the variable reference control. The validity of the proposed strategy is demonstrated through computer simulations

Efeitos do treinamento de dupla tarefa no controle do equilíbrio dinâmico e estático de idosas pré-frágeis: um estudo piloto

The increasing world population of older individuals has become a subject of growing research for prevention and reversibility of the frailty because it is a major risk factor for the occurrence of falls, especially when it involves everyday situations of dual task. Some rehabilitation programs have already used the methods of dual-task with general exercises for improving gait and postural control, but has been reported that these interventions have little specificity with limited success to improve certain aspects of static and dynamic position during the performance of functional tasks. This study aimed to verify the measures of postural control in a group of elderly women with fragility phenotype after physical therapy intervention program based on dual-task treadmill training. We selected six pre-frail elderly subjects, with a minimum age of 65, female, living in the community and randomly assigned to two groups. The survey was conducted twice a week for 45 minutes, for four weeks. The simple task intervention consisted only in training on a treadmill and the dual task consisted of in treadmill training associated with visual stimuli. The assessments were made with the use of the Berg Balance Scale (BBS) and the Balance Master® computerized posturography, static and dynamically. The effects of retention were observed after one month, using the same instruments earlier used. The results showed a tendency toward improvement or maintenance of the balance after training on a treadmill, especially with respect to static equilibrium. Both groups showed the most notable changes in the variables related to gait, as the length and speed. The BBS scores and the baropodometric variables showed that the experimental group could keep all values similar or better even one month after completion of training unlike the control group. We concluded that the dual-task performance had no additional value in relation to the improvement of balance in general, but we observed that the effectiveness of visual stimulation occurred in the maintenance of short term balancevariables

Controle circadiano e homeostático do sono-virgília em pacientes com acidente vascular encefálico e correlações com a qualidade de vida e o nível de atividade física

The cerebral vascular accident is a neurological dysfunction of vascular origin that leds to development of motor sensibility, cognitive, perceptive and language deficits. Despite the fact that the main sleep disorders in stroke patients are well known, it is still necessary to analyze which mechanisms of regulation of sleep and wakefulness are affected. The objective of this study was to evaluate the changes in the circadian and homeostatic control of sleep-wakefulness in stroke patients and the correlations with quality of life and level of physical activity. The study analyzed 22 stroke patients (55± 12 years old) and 24 healthy subjects (57 ±11 years old). The instruments used in this study were questionnaires on sleep quality, daytime sleepiness, quality of life, physical activity level and the actigraphy. The data were analyzed using the Student `t test, Mann-Whitney test, ANOVA and Spearman's correlation tests. The results showed stability in the sleep-wake circadian expression with changes in the amplitude of the rhythm. However, significant changes were found related to the homeostatic component characterized by increased sleep duration, increased latency, fragmented sleep and lower sleep efficiency. Additional data showed decreased quality of sleep and increased daytime sleepiness, as well as decreased quality of life and level of physical activity. The results indicate that the interaction of circadian and homeostatic control of sleep-wake is compromised and the main reason might be because of the homeostatic component and the lower activity level resulting from the brain damage. Thus, further studies may be developed to evaluate whether behavioral interventions such as increased daytime activity and restriction of sleep during the day can influence the homeostatic process and its relation to circadian component, resulting in improved quality of nocturnal sleep in stroke patients

Sair curado para a vida e para o bem: diagramas, linhas e dispersão de forças no complexus nosoespacial do Hospital de Caridade Juvino Barreto (1909-1927)

This work has as object of study the Hospital de Caridade Juvino Barreto, nosocomial institution located in the city of Natal (RN), between the Praia de Areia Preta and the Monte Petrópolis, focusing on the period from 1909, the year in which the new hospital building was constructed and opened, and 1927, the date of the transfer of administration of the public domain to the newly created Sociedade de Assistência Hospitalar (SAH). We study the conditions of possibility of the emergence of this hospital space in the urban environment of the capital of Rio Grande do Norte, seeking to understand the different tactics and strategies implemented by the historical subjects involved in the formation of this institution nosocomial. Starting from a corpus of documents consisting of medical memories (with Dr. Januário Cicco as privileged observer), information present in newspapers (the Republic and the Christmas Journa l), photo collection and extensive administrative and legal material (Speeches, Exhibitions, Reports, Laws and Resolutions), we analyzed in detail the medical geography of HCJB, relating the discourses of medicine and geography in choosing the spatial location of the hospital as we examine the architecture of the hospital, its inner spat iality, divisions, forms of space control, and, finally, we discuss the medical practices that took place within it, leading us in this regard, from the experiences of clinical hospital chief, Dr. Januário Cicco, especially the discussion on "ethics" in hospital work. The perception of HCJB as medical nosoespaciality always on the move, incorporated under taxonomic principles based on difference and dispersion forces, led us to articulate it theoretically from the conceptual-methodological arsenal of philosopher Michel Foucault, particularly his reflections of genealogical phase, focusing on the phenomenon of power, a position that allows us to enhance our space-hospital construction, invention, product of power relations, which give the unfinished aspect nosocômio, apparent, always at stake, perpetual non-modeling possibility has previously defined array, establishing it at the field of possible, of virtuality, of power: hospital that could have been and that it was not. Indeed, the investigation of various aspects/elements of hospital space Juvino Barreto revealed us new dimensions of hospital space, far more complex than the simple and the current idea of a place to shelter patients: plasticity and fluidity of space, which is not made to circumscribe the limits of empeiria, engraving up to strength relations fought between different subject; its Constitution as a transitional space, Heterotopic, doing live inside modern elements with premoderns (professional doctors working with religious thought, skeptical of positivist medicine living with the religious faith of the nuns of Santana); the impossibility of thinking hospital space of HCJB while homogeneous unit, static, transistoric, making the spatiality, without considering the profound differences, fractures and dislocations that animated his own existence, multiplying their expressions of identity

Música dos espaços: paisagem sonora do Nordeste no movimento armorial

This work exams the presence of music in the imaginary constitution of spaces, taking as study s object part of the musical production of the Armorial Movement, officially casted in 1970 in the city of Recife, Pernambuco. From that so called, by the Armorial s discourse, the essence of the brazilian northeastern popular art , the armorialists has intended to make an art that express an idea of northeasternity and brazility . Tries to demonstrate how the music has exerted a basic function of condensation and spreading of the armorial aesthetics, auditorily delimiting the territory of Brazilian Northeastern and, at the same time, trying to impose a sonority to it. This work still analyses the elaboration of what would be a proper soundscape of the Northeastern and how this elaboration passes trough the desire of crystallization of an idealized space, perpetual, escape line of the characteristic modernizing and postmodernizing experience of the twentieth century, product, in turn, of the anxiety of conservation of the Northeastern as a shelter to the traditions that has been evidenced by the construction of an visibility and, also, an audibility to the so called northeastern universe. It analyses, too, the way as works the confrontation between the idea of a so called northeastern soundscape - sonorous events set taken as typical from the rural space - and a sonorous archives series produced since 1920 with the regionalist discourse, showing how was elaborated an armorial music that has intended to represent the brazilian Northeastern. It evidences how, to the elaboration of armorial music, it was managed elements from the European musical culture so called scholar. It argues that the utilization of, to the manufacture of the armorial thinking and aesthetics, of a European mimical capital, so called that way by Stephen Greenblat, was consequence of the intellectual leadership of the Movement, centered in the writer Ariano Suassuna. It argues that Suassuna, followed by the musicians and the artists of the Movement, has searched to evidence a genetic linking between what he has considered the Brazilian true popular art and the medieval Iberian culture. For in such a way, the music was taken as a formation element of the social imaginary and directed to verify a relationship between the Northeastern idealized by the Armorial and the music produced by the Movement. This work has searched, therefore, through the analysis of the armorial music, to study the possible confluences between music and the space that has produced it to, by this analysis, to think the complicity between music and history

Movimento estudantil e serviço social no capitalismo contemporâneo: tendências e particularidades

This dissertation aims to analyze the social direction in which the Student Movement in Social Work in Brazil (ENESSO) has gone through. This is done considering how the functioning of the National Executive, the Brazilian Social Work Student union has operated. The research analyzed their political position regarding the university as well as professional education in the period of 2003 to 2008. The study s theoretical and methodological object was obtained according to its structural, juncture, and time determinants. All of the mentioned elements considered the contemporary capital crisis and its implications towards the State and Society emphasizing specifically the changes that occurred in the University regarding professional education. For the purpose of data collection and production, a documental and field research was realized. Thus, interviews were done considering one manager of each management period of the ENESSO group in the time span of 2003 to 2008. Some subjects that represented the Brazilian Social Work Teaching and Research Association (ABEPSS) as well as were also interviewed. These subjects have had a relevant role in partnership with these entities and represented students in the contemporary scene. Results suggest that ENESSO has developed work that defends a project of a public, free and laic quality university. This entity also defends a project that considers the 1996 Curricular Guidelines. Currently, there is internal dispute in the social direction of the MESS, this is seen amongst political groups that diverge in opinions related to the analysis done by the Lula government regarding the political role that the National Student Union-UNE has taken in the counter-reform of higher education. This current juncture is seen as extremely individualist and it results as in unfavorable for the collective organization of the working class, especially regarding student movement. MESS has been going through a moment of profound instability and this dimension is being expressed by the absence of national coordinator for the 2008/2009 management period at ENESSO. Even though there are difficulties, it is possible to point out partnership of the entities that represent the national Social Work in Brazil. These partnerships are all related to a struggle and search for the development of a professional project that leads towards the sociability awareness that goes beyond capital.

Para compreender a fluidez: os grandes sistemas de movimento viário em Natal/RN

The speed and fluidity are basic requirements for reproduction of big capitalism. Thus, the objects and their actions seek to meet these aspirations of hegemony. And among these objects, there is emphasis on the road systems of movement, made up of bridges, viaducts and tunnels, engineering works that cater to this nee increasingly evident in the current period technical-scientific-informational. So on this premise, it becomes apparent that these objects reflect the technical So on this premise, it becomes apparent that these objects reflect the technical space constitution of Natal, capital of Rio Grande do Norte, where the road systems of movement help to understand the process of fragmentation and and spatial segregation of Natal, accelerated in the late twentieth century. Using the analysis as a tool for urban legislation developed in the capital of RN by the municipal administration, this paper seeks to understand, through a matrix of periodization, as these systems move natalense shaped space and which exists for the hegemonic logic limit the formation and location of each of these systems move road, particularly as it concerns the relationship between these and the expansion of opportunities for certain fluidity between the road systems of movement (fixed), their flow
