Statement of problem. Color stability is an important factor to ensure the long-term clinical success of ceramic restorations. There is a lack of information on how color is affected by fabrication procedures, such as the number of firings. Purpose. The purpose of this study was to evaluate the effects that the number of firings and type of substrate have on the color stability of dental ceramic submitted to artificial accelerated aging. Material and methods. Sixty specimens were fabricated: 30 metal ceramic (Verabond II + IPS d.SIGN) and 30 all-ceramic (IPS d.SIGN). Specimens were divided into 3 groups (n=10), and submitted to 2, 3, or 4 firings (+/- 900 degrees C), respectively, according to the manufacturer`s instructions. Color readings were obtained with a spectro photometer before and after artificial accelerated aging, and L*, a*, and b* coordinates and total color variation (Delta E) were analyzed (2-way ANOVA, Bonferroni, (alpha=05). Results. For metal ceramic specimens, differences for the L* coordinates were significant (P<.05) only for the group submitted to 3 firings. With respect to the all-ceramic specimens, smaller L* coordinates were obtained for greater a* and b* coordinates, indicating that the greater the number of firings...

Considerando as tendências contemporâneas que dinamizam críticas aos novos conhecimentos científicos (Epistemologia) e as insuficiências no processo de produção-ensino-utilização de novos conhecimentos na área médica, as quais compõem parte significativa da realidade na formação acadêmica, esta pesquisa elege como tema de investigação a crítica epistemológica da produção de teses na área da Saúde Reprodutiva. A revisão de elementos teórico-epistemológicos abrange autores ligados à Filosofia e à História da Ciência, destacando-se os pressupostos da obra de Edgar Morin. Tendo em vista as críticas sobre atuações técnico-profissionais que insistem em reproduzir o modelo de pensamento newtoniano-cartesiano ao lado da consciência de novas perspectivas transdisciplinares, apresentam-se as seguintes hipóteses: a) a produção acadêmica em cursos de pós-graduação stricto sensu, na área da Saúde Reprodutiva, apresenta níveis insuficientes de discussão epistemológica relacionada às visões de pessoa, saúde, ciência, ética; b) os processos de produção de novos conhecimentos (pesquisa) e de divulgação (ensino) mantêm a tradição disciplinar e não apresentam elementos teórico-metodológicos suficientes que indiquem condições favoráveis para se trabalhar...

Este estudo investiga a influência da interação imagem-texto de três álbuns ilustrados de língua inglesa no desenvolvimento do repertório linguístico de crianças pré-leitoras. Numa metodologia de estudo de caso, adotando uma abordagem qualitativa e socio construtivista num contexto real de educação pré-escolar, três grupos de crianças portuguesas foram filmados ao longo de várias sessões de leitura repetida em voz alta e em inglês, e de sessões de recontos trabalhados em pequenos grupos. Após a transcrição das gravações, o corpus resultante foi analisado com base numa teoria fundamentada de compreensão literária e em escalas de leitura emergente. Os resultados mostraram que as crianças adotaram uma postura fortemente analítica face aos álbuns, direcionando as suas respostas para as ilustrações e usando-as como apoio na construção de significados. Os resultados mostraram também que cada interanimação visual e verbal ofereceu diversas oportunidades para o uso das línguas em presença, o português e o inglês, tendo o formato e a estrutura inerentes a cada álbum contribuído de forma muito relevante para as respostas das crianças. Contudo, os álbuns com uma dinâmica imagem-texto mais complexa proporcionaram um maior envolvimento das crianças...

OBJECTIVE--To determine whether the number of patients required in a therapeutic trial that uses progression of radiological abnormalities as the outcome measure would be similar for multiple centres. METHODS--The progression of radiological damage to the fingers and wrists of patients with rheumatoid arthritis in five centres, three in North America and two in Europe, was examined. The reproducibility of repeated readings by the same and multiple observers was examined. The number of patients required in a two group trial was calculated for several combinations of power and significance. RESULTS--Scoring progression of radiological abnormalities in sequential films taken between 0.5 and 2.1 years was found to be highly reproducible. When the scores of a single reader were used the rate of change of radiological scores was similar in all centres. Based on the mean progression rate for all centres it was estimated that 153 patients in each group would be required to assure 90% power for detecting a 50% slowing of radiological progression at a significance of 0.05. Review of the experience in three trials showed a large variability in the radiological progression rates. CONCLUSION--The progression of scores for radiological damage in rheumatoid arthritis is relatively uniform in North America and Europe and thus the number of patients required in a trial would be similar. Experience in three trials showed that patient selection is of paramount importance in setting up a successful study.

A brief experimental analysis was used to evaluate the relative effectiveness of combining two consequences (contingent reinforcement or performance feedback) with an antecedent intervention (listening passage preview and repeated readings) on the oral reading fluency of 6 elementary students. The antecedent intervention increased the number of correctly read words per minute for all 6 students. For 4 of the students, pairing the antecedent intervention with either of the consequences resulted in higher reading rates over the antecedent intervention alone. Undifferentiated results were obtained for the remaining 2 participants. These results suggest that combining an antecedent intervention with consequences may enhance the oral reading fluency of students with reading problems. However, individual responsiveness to the different intervention components indicates that brief experimental analyses are warranted to identify the most effective intervention.

1. The attitudes of general practitioners and hospital physicians to the management of hypertension in the elderly, were examined by responses to a postal questionnaire distributed within the Northern Region, concerning the management of a healthy 75 year old male non-smoker with sustained diastolic or isolated systolic hypertension. 2. Two hundred and fourteen (64%) general practitioners and 127 (70%) hospital physicians responded to the questionnaire. General practitioners stated they would most commonly measure to the nearest 2 mm Hg (47%) as compared with nearest 5 mm Hg (61%) by physicians; P < 0.05. When measuring diastolic blood pressure 16% general practitioners and 31% physicians would use phase IV sounds; P < 0.01. 3. Median levels of hypertension, confirmed by repeated readings, at which antihypertensive therapy would be commenced were similar: 180 (150-230)/100(90-120) mm Hg vs 180 (150-200)/100 (90-120) mm Hg; median (range). The stated use of non-pharmacological methods to lower blood pressure before starting drug therapy was similar (74% vs 63%). General practitioners were more likely to prescribe a thiazide diuretic (70% vs 54%) and less likely to prescribe a calcium channel blocker (14% vs 28%) as first line therapy; data for diastolic hypertension...

To determine whether a repeated intraosseous (IO) injection would increase or prolong pulpal anesthesia, we measured the degree of anesthesia obtained by a repeated IO injection given 30 min following a combination inferior alveolar nerve block/intraosseous injection (IAN/IO) in mandibular second premolars and in first and second molars. Using a repeated-measures design, we randomly assigned 38 subjects to receive two combinations of injections at two separate appointments. The combinations were an IAN/IO injection followed approximately 30 min later by another IO injection of 0.9 ml of 2% lidocaine with 1:100,000 epinephrine and a combination IAN/IO injection followed approximately 30 min later by a mock IO injection. The second premolar, first molar, and second molar were blindly tested with an Analytic Technology pulp tester at 2-min cycles for 120 min postinjection. Anesthesia was considered successful when two consecutive readings of 80 were obtained. One hundred percent of the subjects had lip numbness with IAN/IO and with IAN/IO plus repeated IO techniques. Rates of anesthetic success for the IAN/IO and for the IAN/IO plus repeated IO injection, respectively, were 100% and 97% for the second premolar, 95% and 95% for the first molar...

We analyze data collected in a somatic embryogenesis experiment carried out on Zea mays at Iowa State University. The main objective of the study was to identify the set of genes in maize that actively participate in embryo development. Embryo tissue was sampled and analyzed at various time periods and under different mediums and light conditions. As is the case in many microarray experiments, the operator scanned each slide multiple times to find the slide-specific ‘optimal’ laser and sensor settings. The multiple readings of each slide are repeated measurements on different scales with differing censoring; they cannot be considered to be replicate measurements in the traditional sense. Yet it has been shown that the choice of reading can have an impact on genetic inference. We propose a hierarchical modeling approach to estimating gene expression that combines all available readings on each spot and accounts for censoring in the observed values. We assess the statistical properties of the proposed expression estimates using a simulation experiment. As expected, combining all available scans using an approach with good statistical properties results in expression estimates with noticeably lower bias and root mean squared error relative to other approaches that have been proposed in the literature. Inferences drawn from the somatic embryogenesis experiment...

Most individuals who stutter become more fluent during repeated oral readings of the same material. This adaptation effect may reflect motor learning associated with repeated practice of speech motor sequences. We tested this hypothesis with a paradigm that used two integrated approaches to identify the role of motor learning in stuttering adaptation: to distinguish practice effects from situation effects, the texts contained both repeated and novel sentences; to differentiate learning effects from temporary performance effects, stuttering frequency was determined for both the initial adaptation readings and retention tests after 2 and 24 hours. Average group data for 7 stuttering individuals who showed adaptation indicate that (a) both repeated and novel sentences resulted in decreased stuttering frequency across five readings in the initial session, but the decrease was larger for repeated than for novel sentences; (b) after 2 hours, stuttering frequency for both types of sentences was again similar, but with additional readings the repeated sentences once again showed larger improvements in fluency; (c) after 24 hours, prior fluency improvements for the novel sentences had dissipated whereas retention was observed for the repeated sentences. These findings–supporting the hypothesis that motor learning plays a role in stuttering adaptation–were representative for most...

The objective of this study was to evaluate the effects of environmental characteristics on production and milk composition and reproductive activity of primiparous Holstein (PC) race. The experiments were carried out in the Rio whiting, located in Rio Verde, Goiás state Southwest region of the city has two well-defined periods, the rainy season (PCh) (October to April) and dry (PS) (May to September). In the first experiment aimed to evaluate environmental factors such as temperature, relative humidity (RH) and rainfall to estimate Temperature and Humidity Index (THI) in two seasons. The experimental period included the PW during the months of January to April 2011 and the PS to the months of May to August 2012. Through the climate data we calculated the (UTI) by the formula described in NRC (1971). The results showed differences in the variables, minimum, average temperature RH, precipitation and ITU, with higher values for PW. In the second experiment, we used 72 primiparous cows of Holstein breed (PC), aged 24 to 30 months, divided into two experimental groups, with 36 in the PS group and 36 in the PW group. We evaluated the yield and the content of fat, protein, total solids (EST) and defatted (ESD) and milk urea nitrogen (MUN). The experimental design was completely randomized in two periods of measurements (rainy and dry season). There were no differences between the dry and rainy periods for milk production. The values of proximate composition of milk were all different between periods. Values of fat...

This study investigated the effects of repeated readings on the reading abilities of 4, third-, fourth-, and fifth-grade English language learners (ELLs) with specific learning disabilities (SLD). A multiple baseline probe design across subjects was used to explore the effects of repeated readings on four dependent variables: reading fluency (words read correctly per minute; wpm), number of errors per minute (epm), types of errors per minute, and answer to literal comprehension questions. Data were collected and analyzed during baseline, intervention, generalization probes, and maintenance probes. ^ Throughout the baseline and intervention phases, participants read a passage aloud and received error correction feedback. During baseline, this was followed by fluency and literal comprehension question assessments. During intervention, this was followed by two oral repeated readings of the passage. Then the fluency and literal comprehension question assessments were administered. Generalization probes followed approximately 25% of all sessions and consisted of a single reading of a new passage at the same readability level. Maintenance sessions occurred 2-, 4-, and 6-weeks after the intervention ended. ^ The results of this study indicated that repeated readings had a positive effect on the reading abilities of ELLs with SLD. Participants read more wpm...

Students with emotional and/or behavioral disorders (EBD)present considerable academic challenges along with emotional and/or behavioral problems. In terms of reading, these students typically perform one-to-two years below grade level (Kauffman, 2001). Given the strong correlation between reading failure and school failure and overall success (Scott & Shearer-Lingo, 2002), finding effective approaches to reading instruction is imperative for these students (Staubitz, Cartledge, Yurick, & Lo, 2005). ^ This study used an alternating treatments design to comparethe effects of three conditions on the reading fluency, errors, and comprehension of four, sixth-grade students with EBD who were struggling readers. Specifically, the following were compared: (a) Repeated readings in which participants repeatedly read a passage of about 100-150 words, three times, (b) Non-repeated readings in which participants sequentially read an original passage of about 100-150 words once, and (c) Equivalent non-repeated readings in which participants sequentially read a passage of about 300-450 words, equivalent to the number of words in the repeated readings condition. Also examined were the effects of the three repeated readings practice trials per sessions on reading fluency and errors. The reading passage difficulty and length established prior to commencing were used for all participants throughout the standard phase. During the enhanced phase...

This thesis aims to provide a qualitative analysis of the different ways in which students perceive, approach, and learn from literary texts in a non native language (L2). The thesis situates the research in the context of the debate concerning the possible roles of L2 literature by outlining the main arguments, approaches and descriptions of Ll and L2 literature. Barely touched by this literature, however, are L2 learners' experiences of L2 literature and L2 learning models and methods for analysing students' perceptions and approaches to the study of literature. This forms the focus of the research reported here. For the research I conducted as both researcher and educator at the Australian National University I adopted a cross-sectional design. This allowed me to undertake the research in stages, with different groups of students of Italian, to investigate: 1) what students are actually thinking about and doing with L2 literary texts; and 2) ways of improving learning for all L2 students studying L2 literature. Following a preliminary investigation into students' perceptions of literature in 1998, I conducted two main studies in 1999 and 2000. In 1998 I had found that many students perceived literature in general as entertainment and...

O trabalho em saúde apresenta-se como fonte de prazer e de sofrimento. Este estudo exploratório de abordagem qualitativa teve por objetivo identificar os fatores relacionados ao sofrimento psíquico em trabalhadores de enfermagem de uma Unidade de Terapia Intensiva Neonatal de Hospital Universitário da Região Sul do País. Foram entrevistadas uma enfermeira e sete auxiliares de enfermagem em 2004. A análise de conteúdo dos dados deu-se após repetidas leituras e delimitação das seguintes categorias: rígido controle do tempo; forma como o setor é organizado; falta de materiais e equipamentos adequados; conflitos no relacionamento entre os membros da equipe; estado crítico de saúde do paciente; dupla jornada de trabalho feminino; e trabalho nos finais de semana e feriados. Criar espaços para discussões coletivas acerca da gênese do sofrimento psíquico no trabalho pode propiciar o comprometimento dos profissionais com a melhoria da saúde ocupacional e da organização do trabalho.; Working in the health area can be a source of pleasure as well as of suffering. The purpose of this exploratory study, of a qualitative approach, was to identify the factors related to the psychic suffering of nursing workers of the Neonatal UTI of a University Hospital. One nurse and seven nurse assistants were interviewed in 2004. Data content analysis was made by repeated readings and by the delimitation of agglutinant subjects as following: rigid control of the time; the way by which the sector is organized; lack of adequate materials and equipment; conflicts in the relationship among the staff members; critical state of the patient’s health; women double work journey; and work in the weekends and holidays. Creating spaces for collective quarrels concerning the origin of the psychic suffering in the work can stimulate the compromise of the professionals towards the improvement of occupational health and of the work’s organization.; El trabajo en salud se presenta como fuente de sufrimiento y de placer.

Although the literature clearly demonstrates that repeated readings result in immediate effects on students' performance on the intervention materials as well as long-term benefits, data are less promising regarding its immediate generalization effects to similar materials. Using an alternating treatments design, the current study evaluated the effects of a multicomponent repeated reading intervention on generalization passages after students had read a passage three versus six times. Results indicated improvements in fluency as a result of both interventions, with slightly greater maintenance effects when students were given six opportunities to read passages.

Reading fluency is a skill that’s difficult for many students to acquire. However, research suggests that consistently implementing the Repeated Reading intervention can help students increase fluency and comprehension. The effect of this strategy when used to promote reading fluency in secondary students with severe intellectual disabilities has yet to be investigated. My research will examine the effect of the Repeated Reading intervention on the fluency level of students with intellectual disabilities in a public high school.
