Estudo Psicológico de um Caso de Distúrbio de Linguagem

Our intention was to describe the case of a six-year-old boy, carrier of a language disturbance associated to neurological disorders, in language therapy. Our goal was to build instruments for the diagnosis of similar cases. Relating the patient's psychopathological characteristics with a neurological disease, we understood that both results in manifestations of verbal and physical aggressiveness as well as in the severe disturbance of the language. We hope we have contributed to the understanding of the disturbances of communication associated to psychogenic symptoms and of neurological disorders.

Estudo das interferências da ansiedade no estado psicológico de atletas juniores de futebol

O futebol é reconhecidamente o esporte mais praticado no mundo e entre os vários fatores intra e extracampo que podem influenciar no resultado estão os aspectos psicológicos. Muitos jovens sonham em se tornar em se tornar grandes craques e conseguir sucesso, dinheiro e reconhecimento por meio deste esporte. Uma das principais competições para estes é a Copa São Paulo de Futebol Júnior que é um dos maiores torneios de futebol para atletas juniores do Brasil. Sabemos que um dos fatores que mais afetam os atletas é a ansiedade e está diretamente ligado, a importância da competição, de cada jogo, distância de casa, viagem de avião, mudança de hábitos, adaptação ao clima e fuso horário, entre outros aspectos que provocam um aumento da ansiedade.

Acompanhamento psicológico de criança com problema de sono: um relato de caso

Difficulties with sleep are frequent in the pre-schooler children. The aim of this study was to present a case report of behavioural intervention by parental guidance to sleeping problems in a pre-schooler child. Participated in this study a four years old boy that had difficulties to sleep without the presence of his parents and his mother who was oriented through a parental program. The program of intervention was composed by five sessions in which the mother acquired education about the child’s sleep, received orientation about the establishment of time and routine to sleep and about the use of techniques (extinction and positive reinforcement) for the improvement of the sleep difficulties. The sleep and behaviour were evaluated in four periods (pre-treatment, post-treatment, one and six months follow up) according to the following instruments: 1) UNESP Scale of Habits and Hygiene of the Sleep – Children Version, 2) Scale of Sleep Disorders for Children and Teenagers, 3) Child Behavior Checklist (CBCL 1,5-5) and 4) sleep diary. The results showed that after intervention the child developed independent sleep, reduced the bed resistance and showed improvement in daily behaviors. To conclude: a behavioral intervention by parental guidance was effective to sleep problems of the child.

Semi-supervised learning for relevance feedback on image retrieval tasks

Relevance feedback approaches have been established as an important tool for interactive search, enabling users to express their needs. However, in view of the growth of multimedia collections available, the user efforts required by these methods tend to increase as well, demanding approaches for reducing the need of user interactions. In this context, this paper proposes a semi-supervised learning algorithm for relevance feedback to be used in image retrieval tasks. The proposed semi-supervised algorithm aims at using both supervised and unsupervised approaches simultaneously. While a supervised step is performed using the information collected from the user feedback, an unsupervised step exploits the intrinsic dataset structure, which is represented in terms of ranked lists of images. Several experiments were conducted for different image retrieval tasks involving shape, color, and texture descriptors and different datasets. The proposed approach was also evaluated on multimodal retrieval tasks, considering visual and textual descriptors. Experimental results demonstrate the effectiveness of the proposed approach.

Estresse psicológico e desempenho de atletas juniores: uma análise documental

Soccer is one of the most practiced sports in the world, and for many years, some areas of physical education has been doing studies related to the improvement of their income from these areas if this sport psychology. The psychological aspects are very influential and involved in the daily life of an athlete, especially for basic categories of athletes who see in soccer a dream to come true or only a source of income for his family, where such aspects act beneficially or evil for the athlete. Stress, in particular, can appear in various situations and in various ways, and different influences and reactions athlete to athlete, also resulting in physiological changes and variations in performance. Stress, and especially stressful situations, like any psychological aspect should be identified in order to train your athlete to know how to deal with stressful situations. Know what are the stressors, which carries the stress load for the athlete, how to handle the stressful situations, using psychological training in the preseason, know how to use stress management techniques, and be able to manage it all so your athlete reaches an optimal level of income is described in the present work, in order to provide a theoretical and updated reference for professionals of Physical Education, so that they stay up to date on sports psychology and also understand a little more on this subject, which is still little discussed within soccer and often overlooked by many professionals who are already in the context of competitive soccer

Using Descriptive Feedback In a Sixth Grade Mathematics Classroom

In this action research of my 6th grade math class, I investigated whether or not my students would improve their ability to reflect on their learning process when they received descriptive feedback from a peer. I discovered the process of giving and receiving feedback was challenging for the students to initially learn, but eventually using the feedback was highly beneficial. Descriptive feedback allowed the students to learn and understand their mistakes immediately, which in turn improved their learning. In my action research, I also began to discover more ways to implement descriptive feedback in my instruction so it could be more effectively for the students and efficiently so there would be less time taken out from instruction. As a result of this research, I plan to continue having students provide and receive descriptive feedback and to find more evidence of how descriptive feedback could influence student achievement.

Improving the Effectiveness of Independent Practice with Corrective Feedback

In this action research study of my 8th grade Algebra class, I investigated the effects of teacher-to-student written corrective feedback on student performance and attitude toward mathematics. The corrective feedback was given on solutions for selected independent practice problems assigned as homework. Each problem being assessed was given a score based on a 3- point rubric and additional comments were written. I discovered that providing teacher-to-student written corrective feedback for independent practice problems was beneficial for both students and teachers. The feedback positively affected the attitudes of students and teacher toward independent practice work resulting in an improved quality of solutions produced by students. I plan to extend my research to explore ways to provide corrective feedback to students in all of my mathematics classes.

A Qualitative Analysis of Youth Feedback of Nutrition School Enrichment Kits in Lincoln, NE

A Qualitative Analysis of Youth Feedback of Nutrition School Enrichment Kits in Lincoln, NE Richard A. Losey, M.S. University of Nebraska, 2010 Advisor: Wanda M. Koszewski The qualitative analysis of the responses given by students participating in classrooms that used the Nutrition Education Program‟s (NEP) school enrichment kits was the primary focus of this research. Data was collected from the participants in written form. Three major themes appeared during analysis of the data, healthy eating habits, cleanliness and change. The theme of healthy eating habits is comprised of the following sub-themes: breakfast, nutrients, label reading, Food Guide Pyramid/MyPyramid and healthy snacks. Cleanliness is comprised of hand washing and food safety sub-themes. The change theme is made up of change in healthy eating habits, change in cleanliness and change in both healthy eating habits and cleanliness. The data suggests that participating students have made or intend to make changes regarding healthy eating habits and cleanliness, which is the goal of nutrition education. The students‟ responses indicate that the NEP school enrichment kits are effective in increasing the knowledge of students and promoting healthy lifestyle changes.

"IF YOU BUILD THEM UP, THEY WILL STAY": THE ROLE OF RECOGNITION AND FEEDBACK ON STUDENT RETENTION

While such stratagems are certainly well founded, and have achieved varying degrees of success, it may be that a more fundamentally vital area of examination is being largely overlooked, namely the impact of the high school experience.

Manipulation effects of prior exercise intensity feedback by the Borg scale during open-loop cycling

Objective To verify the effects of exercise intensity deception by the Borg scale on the ratings of perceived exertion (RPE), heart rate (HR) and performance responses during a constant power output open-loop exercise. Methods Eight healthy men underwent a maximal incremental test on a cycle ergometer to identify the peak power output (PPO) and heart rate deflection point (HRDP). Subsequently, they performed a constant power output trial to exhaustion set at the HRDP intensity, in deception (DEC) and informed (INF) conditions: DEC-subjects were told that they would be cycling at an intensity corresponding to two categories below the RPE quantified at the HRDP; INF-subjects were told that they would cycle at the exact intensity corresponding to the RPE quantified at the HRDP. Results The PPO and power output at the HRDP obtained in maximal incremental tests were 247.5 +/- 32.1 W and 208.1 +/- 27.1 W, respectively. No significant difference in the time to exhaustion was found between DEC (525 +/- 244 s) or INF (499 +/- 224 s) trials. The slope and the first and second measurements of the RPE and HR parameters showed no significant difference between trials. Conclusions Psychophysiological variables such as RPE and HR as well as performance were not affected when exercise intensity was deceptively manipulated via RPE scores. This may suggest that unaltered RPE during exercise is a regulator of performance in this open-loop exercise.

Decision-directed feedback equalisation for QAM signals

Proposed is a symbol-based decision-directed algorithm for blind equalisation of quadrature amplitude modulation (QAM) signals using a decision feedback scheme. Independently of QAM order, it presents: (i) an error equal to zero when the equaliser output coincides with the transmitted signal; (ii) simultaneous recovery of the modulus and phase of the signal; (iii) a misadjustment close to that of the normalised least-mean squares algorithm; (iv) fast convergence; and (v) the avoidance of degenerative solutions. Additionally, its stability is ensured when the step-size is properly chosen.
