Fish assemblages associated with oil industry structures on the continental shelf of north-western Australia

This study provides the first assessment of fish associations with oil and gas structures located in deep water (85-175 m) on Australia's north-west continental shelf, using rare oil industry video footage obtained from remotely operated vehicles. A diverse range of taxa were observed associating with the structures, including reef-dependent species and transient pelagic species. Ten commercially fished species were observed, the most abundant of which was Lutjanus argentimaculatus, with an estimated biomass for the two deepest structures (Goodwyn and Echo) of 109 kg.

Predictors of individual player match performance in junior Australian football

PURPOSE: Player match statistics in junior Australian football (AF) are not well documented while contributors to success are poorly understood. A clearer understanding of the relationships between fitness and skill in younger age players participating at the foundation level of the performance pathway in AF has implications for the development of coaching priorities (e.g., physical or technical). The aim of this study was to investigate the relationships between indices of fitness (speed, power and endurance) and skill (coach rating) on player performance (disposals and effective disposals) in junior AF. METHODS: Junior male AF players (n = 156, 10 - 15 years old) were recruited from 12 teams of a single amateur recreational AF club located in metropolitan Victoria. All players were tested for fitness (20 m sprint, vertical jump, 20 m shuttle run) and rated by their coach on a 6-point Likert scale for skill (within a team in comparison to their teammates). Player performance was assessed during a single match in which disposals and their effectiveness were coded from a video recording. RESULTS: Coach rating of skill displayed the strongest correlations and combined with 20 m shuttle test showed a good ability to predict both disposals and the number of effective disposals. None of the skill or fitness attributes adequately explained the percentage of effective disposals. The influence of team did not meaningfully contribute to the performance of any of the models. CONCLUSION: Skill development should be considered a high priority by coaches in junior AF.

Prosecutors’ perceptions of how to improve the quality of evidence in domestic violence cases

Limited evidence in domestic violence prosecutions is a persistent problem. Focus groups with 13 prosecutors from across Australia and New Zealand were used to explore how to improve the quality of evidence collected and presented in these cases. A thematic analysis identified three main strategies: improving the quality of investigations by initial police responders, supporting the complainant and tailoring the trial process to the domestic violence context. The most discussed strategy within these categories has previously received little attention– police video recording the complainant's initial account and using that video as the basis for the complainant's courtroom testimony.

Uma ação reflexiva sobre o processo de (re)escrita de textos: a prática pedagógica da professora Maria

T he reflexive action on the process of texts (re)writing, central topic of this study, is still a challenge within the elementary school. What made this issue a special theme of study was the fact that the chosen focus is based on a lived experiences with (re) writing activities where the uniqueness of the professional practice would be transformed into a place of knowledge production, offering theoretical and a practical support to a teacher, in order to understand the interactive nature of language as a space for recovery of the individual (as a historical, social, and cultural being). The empirical field research, structured in the light of assumptions of qualitative research into the action research format, was a public school in Bahia, in a third grade classroom. The instruments of data collection were open questionnaire, semistructured interviews, observations with video recording, documentary analysis of texts produced by students, and reflective sessions. The objectives that supported the research study were: 1) Investigate, in the pedagogical action of teacher Maria, activities on the writing process, 2) Interact with the teacher, in the form of action inquiry to: a) reflect on the procedures for theoretical and methodological development of reflective practice on the process of the (re) writing of the text, b) intervene in the construction of didactic situations that enable the learning and the development of reflexive actions in the (re) writing of texts. To accomplish these goals, it was established as a commitment a dialogic communication with the protagonist, providing reflection sessions so she could examine her teaching practices. The most relevant theoretical arguments to the establishment of this research came from the theoretical and methodological approaches of Bakhtin s theory of enunciation-discourse (2003, 2004) and Vygotsky s socio-interactionist theory (1989, 1998), as it is believed that both theories, through a paradigm shift, in which the constitution of the individual and the participation of others in the actions of analysis and reflection on the language, would give opportunities for internalization and construction of knowledge. The systematic and critical pondering led the participating teacher into reviewing her teaching praxis, compelling her to promote a more insightful understanding of the writing process of her students. That experirence brought into evidence three categories of actions: 1) actions that reflect the technical rationalism, 2) actions that reflect an emancipatory metamorphosis, and 3) actions that reflect empowerment and awareness. The results confirm that the action / reflection on the process of the (re) writing of a text has a dimension of increasing levels of awareness and self criticism, reproducing other meanings for teaching praxis

Já li muita coisa, então, eu posso inventar mais! A leitura literária e o desenvolvimento do pensamento criativo na infância

This study investigates the contributions of reading literature for the development of creative thinking in childhood. Its relevance consists in exploring practices that contemplate the creative thinking development in apprentices at school space and understanding the literature like a significant way to promote the creative thinking. The study is connected to the qualitaty strand. The exploratory observation and the intervention were adopted as research techniques. The field diary and the audio and video recording of the reading sections were adopted as methodological instruments. The research was conducted in the application s college from the Federal University of Rio Grande do Norte, in a 1th grade class, with 18 students between 6 and 7 years old. During the intervention, 8 readind class happened, with varied strategies and literary genres. The reading sessions were conducted through the principles of scaffolding, defended by Graves and Graves (1995). The corpus is made of speaks episodes, whose encoding semantics allowed the grouping into two central categories: divergent thinking and coauthoring of literary reader. It was taken as a theoretical framework the studies of Amarilha (2011; 2006; 2001; 1991; 1993; 1994), Alencar (2001), Coelho (2000; 1997), Culler (1999), De Masi (2005), Gallo (2000), Guilford (1977), Iser (1996), Jouve (2002), Kneller (1978), Martínez (1997), Smith (2003), Stierle (1979), Vigotski (2009; 1998), Wechsler; Nakano (2003; 2002). The analysis points to the formation of creative individuals in the classroom, through the reading of literature. Reposition the literary education front of the new social demands. Resizes the function of school in children s development, considering the children s skill in exploring, testing hypotheses and making use of their creative thinking, in climate of freedom mental. It signals, in this way, the teacher like a mediator, promoting a favorable to the development of creative thinking environment, a stimulating atmosphere, which enhances the expression of creative thinking in community

A linguagem da reflexão de uma professora de Língua Inglesa: um estudo de caso sob a perspectiva do sistema de avaliatividade

Research about teacher education, carried out in the area of Applied Linguistics (AL), reveals the importance of reflective practices in the professional development of teachers. With the aim of contributing to this area, we present this case study conducted at a technical school in Natal, RN. The corpus of the study is formed mainly from the teacher‟s discourse, generated during a stimulated recall session and the instruments used to collect the data: an initial questionnaire, a video recording of a class and the text transcript of the stimulated recall session. The central objective is to understand the way in which the reflection-on-action (SCHÖN, 1983, 1987) can contribute to raise the awareness of an English as a Foreign Language teacher (EFL) about her actions in the classroom. With this proposal, we begin our discussion presenting the origins, the presuppositions and characteristics of the concept of reflection according to Schön (1983, 1987), and supported by other authors (PERRENOUD, 2002; GÓMEZ, 1995; IMBERNÓN, 2009, among others); of critical reflection (LISTON e ZEICHNER, 1993; PIMENTA, 2002; DUTRA e MELLO, 2004, among others); and of the process of critical reflection (SMYTH, 1992). To evidence the reflections that emerge in the teacher‟s discourse, we found support in the theories and methods of Systemic Functional Grammar (SFG), which was initially proposed by Halliday (1985, 1994), Halliday and Hasan (1989), Halliday and Matthiessen (2004) and followers, such as, Eggins (1994), Thompson (1996), among others. We focus mainly on the subsystem of Attitude, an integral component of the system of discourse resources, Appraisal, presented by Martin (2000), Martin and Rose (2003, 2007), Martin and White (2005). The results reveal that the actions of the teacher in the classroom reflect not only her professional experiences, but also her values and concepts about teaching/learning languages. The results also show the teacher‟s awareness of the need for changes in her practices. Faced with these findings, we believe that this study reveals important concepts that can direct teacher educators to rethink new ways of approaching teacher training courses. In addition, it also reveals the importance of discourse analysis based on a systemic functional approach.

O hipertexto eletrônico de meio ambiente : estratégias de leitura e navegação

The incorporation of computing in class instigate the use of the Internet and websites as a content support in the teaching/leaning process. This kind of practice had challenged the students to read through eletronic hypertextual means. In that way, we re trying to undestand which strategies of reading and navigation the students of the second and third grade of highschool levels are using when reading electronic hypertexts from the www.ambientebrasil.com.br website. The research took place in the Escola Estadual Jerônimo Rosado in Mossoró RN. Our theoretical base was estructured on the digital Technology (electronic hypertext estructure and it s navigation modes), in applied linguistics (act of reading) and in cognition (interaction of the reader with the text and the use of reading strategies in the virtual computing enviroment). The applied methodology was the case analysis which was developed with the reunion of collected data through qualitative reseach questionaries, direct observations and video recording sessions. The research demonstrates that reader s ability in the act of navigating on virtual sites activates his/her reading strategies. Also shows how the semantic architecture of the hyperlinks can interfere directly over the strategies of reading and navigation in specific websites. Our research also intend to demonstrate that the student use his strategies of linear text reading when are not accustomed to use the reading through websites in a regular basis. The investigation concludes observing that the amount of hypertexts per pages and the inappropriate use of the multimedia elements were harmful to the reading fluency

Comparison of two methods (visual estimates and filming) for counts of horn flies (Haematobia irritans irritans) (L.) (Diptera : Muscidae)

Visual estimates are generally used for counts of horn flies, Haematobia irritans (L.) and play an important role as an instrument to quantify fly populations in scientific studies. In this study, horn fly counts were performed on 30 Nelore steers in the municipality of Aracatuba, SP Brazil, from January to December 1998. Flies were counted weekly by two methods: the estimate method whereby estimates of the number of flies on one side of the animal are obtained by visual observation, and the filming method whereby images of flies from both sides of the animal are recorded with a video camera. The tape was then played on a videotape recorder coupled to a television and the flies were counted on the screen. Both methods showed variations in horn fly population density during the period studied. However, significant differences (p < 0.05) were observed between the two methods with the filming method permitting the visualization of a larger number of flies than the estimate method. In addition, the filming method permitted safe and reliable counts hours after the images were taken, with the advantage that the tape can serve as an archive for random re-counts.

A comparison of nasopharyngeal endoscopy and lateral cephalometric radiography in the diagnosis of nasopharyngeal airway obstruction

Two auxiliary methods of diagnosing nasopharyngeal airway obstruction were compared. Cephalometric radiography and nasopharyngeal videoendoscopy were evaluated for efficacy in terms of reproducibility and validity. Thirty orthodontic patients (7 to 12 years of age) seeking otorhinolaryngologic treatment for mouth breathing, or mouth and nose breathing, had nasopharyngeal endoscopy and radiographic examinations performed on the same day. Two otorhinolaryngologists analyzed the results. Nasopharyngeal endoscopy was more reliable in identifying all the obstructive nasopharyngeal processes. Endoscopy obtained kappa index scores of almost perfect agreement for diagnosis of posterior nasal septum deviation, of substantial agreement for anterior nasal septum deviation and lower turbinate hypertrophy, and of moderate agreement for middle turbinate hypertrophy. Lateral cephalometric radiography obtained scores of perfect agreement for imaging hypertrophy of the middle turbinate, of almost perfect agreement for imaging hypertrophy of the posterior portion of the inferior turbinate, and of substantial agreement for imaging hypertrophy of the inferior turbinate. Radiographic diagnoses of hypertrophy of the middle and lower turbinates exhibited high sensitivity and low specificity when compared with diagnoses by nasopharyngeal endoscopy.

Digital monitoring of broiler breeder behavior for assessment of thermal welfare

The assessment of welfare issues has been a challenge for poultry producers, and lately welfare standards needs to be reached in order to agree with international market demand. This research proposes the use of continuous behavior monitoring in order to contribute for assessing welfare. A software was developed using the language Clarium. The software managed the recording of data as well as the data searching in the database Firebird. Both software and the observational methodology were tested in a trial conducted inside an environmental chamber, using three genetics of broiler breeders. Behavioral pattern was recorded and correlated to ambient thermal and aerial variation. Monitoring video cameras were placed on the roof facing the used for registering the bird's behavior. From video camera images were recorded during the total period when the ambient was bright, and for analyzing the video images a sample of 15min observation in the morning and 15 min in the afternoon was used, adding up to 30 min daily observation. A specific model so-called behavior was developed inside the software for counting specific behavior and its frequency of occurrence, as well as its duration. Electronic identification was recorded for 24h period. Behavioral video recording images was related to the data recorded using electronic identification.. Statistical analysis of data allowed to identify behavioral differences related to the change in thermal environment, and ultimately indicating thermal stress and departure from welfare conditions.

Interação de um aluno com paralisia cerebral com colegas de classe durante atividades ludicas

The study aimed to examine the quality of interpersonal relationships developed between a child with cerebral palsy (CP) and his classmates during group play activities carried out in the classroom and during recess. The participants of the study were a boy with clinical diagnosis of quadriplegic CP, his teacher and classmates. Data collection was carried out by means of a structured interview with the teacher and of video recording the child with CP interacting with his classmates in play activities. The interview data analysis was carried out using qualitative procedures and the video recording was analyzed using a category system. The results showed that the teacher perceived the child with CP to be interested; he participated in play activities and interacted successfully both with familiar partners and with all classmates in general. On the other hand, the analysis of the video recorded activities showed that even though interaction did in fact occur positively, the child with CP remained mostly an observer of the activities rather than an active participant, possibly due to the gap between the child's possibilities and the requirements imposed by the activities underway in the school setting.

Components of the acoustic swallowing signal: Preliminary study

Purpose: To analyze the components of the acoustic signal of swallowing using a specific software. Methods: Fourteen healthy subjects ranging in age from 20 to 50 years (mean age 31±10 years), were evaluated. Data collection consisted on the simultaneous capture of the swallowing audio with a microphone and of the swallowing videofluoroscopic image. The bursts of the swallowing acoustic signal were identified and their duration and the interval between them were later analyzed using a specific software, which allowed the simultaneous analyses between the acoustic wave and the videofluoroscopic image. Results: Three burst components were identified in most of the swallows evaluated. The first burst presented mean time of 87.3 milliseconds (ms) for water and 78.2 for the substance. The second burst presented mean time of 112.9 ms for water and 85.5 for the pasty substance. The mean interval between first and second burst was 82.1 ms for water and 95.3 ms for the pasty consistency, and between second and third burst was 339.8 ms for water and 322.0 ms for the pasty consistency. Conclusion: The software allowed the visualization of three bursts during the swallowing of healthy individuals, and showed that the swallowing signal in normal subjects is highly variable.

Estimation of spontaneous blinking main sequence in normal subjects and patients with Graves' upper eyelid retraction

Purpose. We quantified the main sequence of spontaneous blinks in normal subjects and Graves' disease patients with upper eyelid retraction using a nonlinear and two linear models, and examined the variability of the main sequence estimated with standard linear regression for 10-minute periods of time. Methods. A total of 20 normal subjects and 12 patients had their spontaneous blinking measured with the magnetic search coil technique when watching a video during one hour. The main sequence was estimated with a power-law function, and with standard and trough the origin linear regressions. Repeated measurements ANOVA was used to test the mean sequence stability of 10-minute bins measured with standard linear regression. Results. In 95% of the sample the correlation coefficients of the main sequence ranged from 0.60 to 0.94. Homoscedasticity of the peak velocity was not verified in 20% of the subjects and 25% of the patients. The power-law function provided the best main sequence fitting for subjects and patients. The mean sequence of 10-minute bins measured with standard linear regression did not differ from the one-hour period value. For the entire period of observation and the slope obtained by standard linear regression, the main sequence of the patients was reduced significantly compared to the normal subjects. Conclusions. Standard linear regression is a valid and stable approximation for estimating the main sequence of spontaneous blinking. However, the basic assumptions of the linear regression model should be examined on an individual basis. The maximum velocity of large blinks is slower in Graves' disease patients than in normal subjects. © 2013 The Association for Research in Vision and Ophthalmology, Inc.
