Efeitos da deriva de clomazone, aplicado isoladamente ou em mistura com ametryn, sobre características produtivas de laranjeira 'Hamlin'

This experiment aimed to evaluate the effect of increasing clomazone (sprayed alone or in mixture with ametryn) drift simulation on quantitative and qualitative aspects of orange production when applied at two developmental plant stages: flowering and initial fruit development (fruits 2 cm diameter or smaller). Increasing drifts of clomazone, in two formulations, and clomazone in mixtures with ametryn were tested. Fruit morphological features, fruit color, flower and fruit abortion and leaf chlorophyll content were evaluated. Simulated drift similar to the recommended dose of clomazone and clomazone plus ametryn caused fruit abortion in citrus at the stage of fruits 2 cm diameter or smaller. Lower drift doses did not result in fruit abortion. Fruit diameter reduction was observed with drift off above 25% of clomazone alone recommended rate and 50% when in mixture with ametryn or in microcapsule formulation. Clomazone drift at 50% of the recommended rate (alone or in mixture with ametryn ) caused clorotic and necrotic spots in the fruit peel. Drift did not affect juice quality in any of the treatments tested.

Dretske e o problema dos qualia

The aim of this paper is to present and discuss Fred Dretske's (1995) suggestion for analysis of the problem of qualia. Such a problem was acknowledged following Thomas Nagel's discussion in his classical paper What is it like to be a bat. In the paper, Nagel (1974) postulates the impossibility of knowing aspects of human experience from a third-person perspective. He considers that qualitative aspects of a subject's experience, fundamental for characterization of qualia, would be lost during the course of objective descriptions of it. Based on his Representational Thesis of Mind, Dretske argues that if we were to consider mind to be the representational aspect of the brain, the nature of qualia would thus be representational. In this context, mental facts related to experiences would be representational facts: if we were to know the nature of these representational facts, we would also know the experience the system represents. Given this understanding, we discuss to what extent the Dretskean proposal constitutes (or not) an alternative for the problem of qualia.

Desempenho de escolares com dificuldades de aprendizagem em funçào motora fina e escrita

Aims: the aims of this study were to compare and to characterize the fine, sensory and perceptive function performance and handwritten quality between students with learning difficulties and students with good academic performance. GII, GIII and GIV: 96 students with learning difficulties, and groups GV, GVI, GVII, GVIII: 96 good academic performance. The students were submitted to evaluation of fine motor, sensorial and perception functions and handwriting evaluation under dictation. Results: the results show that the students with learning difficulties from 1st to 3rd grade had lower performance on tests of fine motor, sensory and perceptive function compared to the students with good academic performance in the same grade; the students from 4th grade, both groups, did not show changes on fine motor sensory and perceptive function; and only the students of GII showed disgraphya. Conclusions: the results presented in this study suggest that the qualitative aspects of fine motor, sensory and perceptive skills reflect the integrity and maturity of central nervous system and can probably play an important role in early diagnosis of development disorders and consequently prevent academic disorders such as handwriting performance.

A variação sócio-cultural e o ensino de língua portuguesa no ensino fundamental: por uma pedagogia sensivelmente cultural

This study aimed to gather information about the social and linguistic reality of students 1. years of elementary school and community that came, in order to identify aspects of their lexical phonological levels, morphological and morphosyntactic and thus identify and describe the alternative variants of non-standard rule. The methodology chosen was that of variational sociolinguistics addressing quantitative and qualitative aspects in the treatment of the data collected through participant observation and audio recordings of speeches of the students. The results indicate that the level of phonological variants are the most frequent in the speech of students. Because the literacy phase, how the student speaks serves you a guide to the act of writing, so it is necessary to work with the students the difference between oral and written form and monitoring of these two modes according to the context of the discourse

Connections between the Sznajd model with general confidence rules and graph theory

The Sznajd model is a sociophysics model that is used to model opinion propagation and consensus formation in societies. Its main feature is that its rules favor bigger groups of agreeing people. In a previous work, we generalized the bounded confidence rule in order to model biases and prejudices in discrete opinion models. In that work, we applied this modification to the Sznajd model and presented some preliminary results. The present work extends what we did in that paper. We present results linking many of the properties of the mean-field fixed points, with only a few qualitative aspects of the confidence rule (the biases and prejudices modeled), finding an interesting connection with graph theory problems. More precisely, we link the existence of fixed points with the notion of strongly connected graphs and the stability of fixed points with the problem of finding the maximal independent sets of a graph. We state these results and present comparisons between the mean field and simulations in Barabasi-Albert networks, followed by the main mathematical ideas and appendices with the rigorous proofs of our claims and some graph theory concepts, together with examples. We also show that there is no qualitative difference in the mean-field results if we require that a group of size q > 2, instead of a pair, of agreeing agents be formed before they attempt to convince other sites (for the mean field, this would coincide with the q-voter model).

Interactive Processes among Babies at a Daycare Center

The paper presents a study regarding babies' interactive processes with peers, which aimed to apprehend some of their qualitative aspects, considering babies' peculiarities. An empirical work was conducted with video recording scenes and interviews, regarding the "Babies' Adaptation to a Daycare Center" project, which followed up 21 babies (4-13 months) at a daycare center. Data analysis was based on the Network of Meanings perspective. Five episodes are here presented regarding three focal subjects and their peers. Analysis indicates the occurrence of interactions; among them it can be highlighted the role of the glance, presence of triadic relations (even among babies younger than nine months old), abbreviation of communicative resources and empathy. Moreover, despite verbal language absence at this age, it was verified meaning processes. Some practical-theoretical implications are pointed out as well.

Does ragging play a role in medical student depression - Cause or effect?

Background: Medical students experience a lot of stress what may contribute to symptoms of depression. In this study we set out to look at the environmental factors which may be contributing in one medical school in Brazil. Methods: We assessed depressive symptoms using Beck's Depression Inventory in 465 and 267 medical students in 2001 and 2006 respectively. We explored possible social and environmental causes using qualitative data. Results: Nearly 15% scored above the cut off for depression in both the samples. Males in the pre-clinical stage in 2006 showed an increase in depressive symptoms than males in the same cycle in 2001 (aOR = 7.36 [95% CI = 0.85-63.5] p = 0.07). Qualitative data confirmed that factors such as ragging and low social involvement were correlated with depressive symptoms in pre-clinical stage males. Limitations: The sample size was small both for quantitative and qualitative aspects of the study. Conclusions: It appears that ragging plays an important role in the genesis of depressive symptoms in medical students. (C) 2012 Elsevier B.V. All rights reserved.

Optical aids for low vision: use of the Internet to guide teachers of the visually impaired

PURPOSES: To describe and interpret teachers' opinions about and responsiveness to guidance on optical aids for low vision. METHODS: It was conducted a cross-sectional analytical study. The convenience, non-random sample consisted of 58 teachers from the public school network of the city of Campinas. It was constructed and applied a structured questionnaire, available online at the assessed website. For qualitative data collection it was conducted an exploratory study using the focus group technique. RESULTS: Responses expressed, for the most part, a marked interest in the website, its easiness of access, and the comprehensive nature of the information provided. Most people reported frequent use of the Internet to seek information, and found it easier to access the Internet at home. Among the qualitative aspects of the evaluation, we should mention the perceived importance of the website as a source of information, despite some criticism about the accessibility and reliability of the information found on the Internet. CONCLUSION: Teachers' need for training to deal with visually impaired students and their positive response to advice and information lead to the conclusion that web-based guidelines on the use of optical aids were considered beneficial to ease the understanding of visual impairment and the rehabilitation of the affected subjects.

Applicazioni industriali e di ricerca della spettroscopia NIR per la valutazione di indici qualitativi di prodotti alimentari

In the present work qualitative aspects of products that fall outside the classic Italian of food production view will be investigated, except for the apricot, a fruit, however, less studied by the methods considered here. The development of computer systems and the advanced software systems dedicated for statistical processing of data, has permitted the application of advanced technologies including the analysis of niche products. The near-infrared spectroscopic analysis was applied to the chemical industry for over twenty years and, subsequently, was applied in food industry with great success for non-destructive in line and off-line analysis. The work that will be presented below range from the use of spectroscopy for the determination of some rheological indices of ice cream applications to the characterization of the main quality indices of apricots, fresh dates, determination of the production areas of pistachio. Next to the spectroscopy will be illustrated different methods of multivariate analysis for spectra interpretation or for the construction of qualitative models of estimation. The thesis is divided into four separate studies that consider the same number of products. Each one of it is introduced by its own premise and ended with its own bibliography. This studies are preceded by a general discussion on the state of art and the basics of NIR spectroscopy.
