AbstractRecent prevalence estimates for autism have been alarming as a function of the notable increase. Speech-language pathologists play a critical role in screening, assessment and intervention for children with autism. This article reviews signs that may be indicative of autism at different stages of language development, and discusses the importance of several psychometric properties—sensitivity and specificity—in utilizing screening measures for children with autism. Critical components of assessment for children with autism are reviewed. This article concludes with examples of intervention targets for children with ASD at various levels of language development.

Working with faith communities in health promotion is widely acclaimed and yet not readily practiced. This article describes a study conducted among four faith communities to determine the process required for sustainable faith-based programs. Face-to-face interviews were conducted among 12 community volunteers who participated to identify their perceptions of the project. Two staff members were also interviewed to identify the process from their perspectives. Project-related documents were also analyzed to provide details and triangulate the data from the interviews. The study followed the project for 2 ½ years. Several factors were identified as significant influences on participation and project sustainability. These included value, active pastoral support, program success, and volunteer commitment. The results of this study indicate that pastoral support and faith community ownership are critical components that should be included in faith-based community building efforts.

A competição Fórmula SAE ocorre anualmente em diversos lugares do mundo. No Brasil acontece em Piracicaba, e envolve estudantes de diversas universidades de todo o país, e, inclusive estrangeiras. O objetivo da competição é de que as equipes desenvolvam um protótipo de carro de corrida tipo fórmula, que será avaliado em diversas provas, desde estáticas à dinâmicas. Parte fundamental do desenvolvimento do protótipo é a concepção da transmissão, pois esta é responsável pela transferência de torque e potência do motor às rodas do protótipo. O projeto deve ser feito de modo a proporcionar elevado torque às rodas em velocidades relativamente baixas do veículo, pois, devido ao fato de que a pista do evento brasileiro tem poucas retas, a rápida recuperação de velocidade é um fator de maior importância para o bom desempenho do carro em detrimento da velocidade máxima do mesmo. Para se obter essas características de comportamento do veículo, busca-se uma razão adequada entre o número de dentes da coroa (engrenagem que transmite o torque as rodas) e do pinhão (engrenagem na saída do motor). Para esta seleção utilizou-se dados de torque máximo, e sua respectiva rotação, sendo este dado fornecido pelo fabricante do motor utilizado no carro, o qual corresponde ao modelo da moto XT660 da Yamaha. Foram analisadas diversas relações, através de gráficos do tipo dentes de serra, que fornecem a velocidade do veículo pela rotação em cada marcha, selecionando-se, assim, a relação que possibilitasse a troca de marcha do veículo com a menor perda de torque possível, mantendo uma boa evolução de velocidade. Da análise destes dados obteve-se que o valor de relação mais adequado ao sistema é de 3/1, ou seja, a coroa deve ter uma quantidade de dentes 3 vezes maior que o pinhão.

Abstract UDIMET 718 is a nickel-base alloy that is precipitation hardenable. It exhibits exceptionally high yield strength up to 1300 F, excellent cryogenic properties down to -423 F and superior weldability even in the fully-aged condition. This unusual combination of characteristics makes it suitable for elevated-temperature applications in gas turbines and in critical components for missiles. This datasheet provides information on composition, physical properties, elasticity, and tensile properties as well as creep. It also includes information on forming, heat treating, machining, joining, and surface treatment. Filing Code: Ni-258. Producer or source: Special Metals Corporation.

BACKGROUND Evaluating Health Information System (HIS) quality is strategically advantageous for improving patient care quality. Nevertheless, there is little research evidence identifying and describing what standards, processes, and tools are used to evaluate HIS quality. OBJECTIVE This study aims to illustrate, detail, and discuss the current scenario regarding the standards, norms, processes, and tools used to evaluate HIS quality. METHODS We conduct a systematic literature review (SLR) using review guidelines focused on software and systems. We examined seven electronic databases (Scopus, ACM, ScienceDirect, Google Scholar, IEEE Xplorer, the Web of Science and PubMed) to search and select primary studies. Three researchers and three collaborators participated in the review and quality assessment process of the studies. RESULTS We identified 17 primary studies that have been published in journals and conferences. We found that most of the primary studies address quality evaluation from a management perspective. Second, there is little explicit and pragmatic evidence on the processes and tools that allow evaluation of HIS quality. CONCLUSIONS To promote quality evaluation of HISs, it is necessary to define mechanisms and methods that operationalize the standards and norms of HISs. Additionally, it is necessary to create metrics that measure the quality of the most critical components and processes of HISs. CLINICALTRIAL Does not apply to our study
