Polyana Candeia Maia 28 February 2013 (has links)
A avaliaÃÃo do desenvolvimento infantil à necessÃria para que haja o monitoramento e o acompanhamento das mudanÃas ocorrentes na vida da crianÃa, buscando identificar as caracterÃsticas prÃprias e relacionÃ-las com os respectivos perÃodos de desenvolvimento do ser humano. O estudo objetivou avaliar o desenvolvimento neuromotor de crianÃas com idade de 2m15d a 12m15d. Estudo descritivo-exploratÃrio, transversal, com enfoque analÃtico, realizado em Centro de SaÃde da FamÃlia nos municÃpios de Fortaleza e Sobral, CearÃ, Brasil. A amostra foi composta por 330 crianÃas e seus respectivos pais/responsÃveis, 165 em cada municÃpio referido. A coleta de dados ocorreu de marÃo a junho/2012, utilizando Harris Infant Neuromotor Test (HINT) versÃo brasileira e Instrumento de VigilÃncia do Desenvolvimento do MinistÃrio da SaÃde (Caderneta de SaÃde da CrianÃa), formulÃrio contendo dados sociodemogrÃficos dos pais/cuidadores. A coleta de dados se deu apÃs aprovaÃÃo pelo Comità de Ãtica em pesquisa da Universidade Federal do CearÃ. Os dados foram organizados no programa Excel e analisados no SPSS versÃo 18 e para todos os testes foi utilizado o Intervalo de ConfianÃa de 95% (p<0,05). Os resultados mostraram que 52 crianÃas de Fortaleza estavam na idade de 2m15d a 3m15d, e, em Sobral, 47 estavam na idade de 11m16d a 12m15d. De acordo com os dados, houve associaÃÃo estatÃstica significante entre o tipo de parto e os dois municÃpios (p=0,020) e o estado civil das mÃes de Fortaleza com os escores finais do HINT (p=0,035). Houve diferenÃa significativa do Instrumento de VigilÃncia do Desenvolvimento do MinistÃrio da SaÃde entre crianÃas nascidas a termo e prÃ-termo de Fortaleza (p=0,000) e Sobral (p=0,000) e da renda familiar em Sobral (p=0,022). NÃo houve diferenÃa estatisticamente significante entre os dois municÃpios ao se associar as variÃveis sociodemogrÃficas renda, tipo de chÃo, esgoto e coleta de lixo. Quanto aos questionamentos do HINT direcionado aos responsÃveis pelas crianÃas, em Fortaleza, 117 pais afirmaram sentir o bebà âsÃlido e firmeâ, 88 que a movimentaÃÃo da crianÃa era âexcelenteâ e 85 relataram que os filhos estavam âacima do padrÃo esperadoâ ao serem comparadas com outras da mesma idade. Em Sobral, 132 pais afirmaram sentir o filho âsÃlido e firmeâ, 92 que a movimentaÃÃo era âexcelenteâ e 87 que o filho estava âde acordo com a idadeâ. O resultado da avaliaÃÃo do desempenho neuromotor por meio do HINT mostrou que a maioria das crianÃas, 98 (59,3%) em Fortaleza, pontuou com escore normal e ao serem avaliadas com o Instrumento de VigilÃncia do Desenvolvimento do MinistÃrio da SaÃde (Caderneta de SaÃde da CrianÃa), 127 (77%) em Fortaleza e 144 (87,3%) em Sobral, foram classificadas com o desenvolvimento adequado. Entretanto, os dois instrumentos nÃo mostraram correlaÃÃo significativa entre si (K = -0,010). Apesar disso, os dois instrumentos pertinentes para uso com a clientela estudada, apresentando vantagens e desvantagens, exigindo que novas pesquisas sejam realizadas com amostras e delineamentos diferentes. / The evaluation of infant development is necessary to monitor and follow-up changes in childrenâs lives, seeking to identify their own characteristics and relate them to the respective human development stages. This study aims at evaluating motor development in children aged 2m15d to 12m15d. It is a descriptive-exploratory transversal study with an analytic approached carried out in Family Health Centers in the municipalities of Fortaleza and Sobral, CearÃ, Brazil. The sample is composed of 330 children and their respective parents/caregivers, 165 from each referred municipality. Data collection took place from March to June 2012 using the Harris Infant Neuromotor Test (HINT) Brazilian version and the Ministry of Health Development Control Protocol, a form that includes socio-demographic data on parents/caregivers. Data was collected after approval granted by the Cearà Federal University Research Ethics Committee. Data was organized in Excel charts and analyzed through the SPSS version 18, and a Confidence Interval of 95% (p<0.05) was applied to all tests. Results showed that 52 Fortaleza children were aged 2m15d to 3m15d whereas in Sobral, 47 were between 11m16d and 12m15d. According to data, there was a significant statistical correlation between the baby delivery method and the two municipalities (p=0.020) and the marital status of Fortaleza mothers with the HINT final scores (p=0.035). There was also a remarkable difference in the Ministry of Health Development Protocol between term and preterm babies in Fortaleza (p=0.000) and Sobral (p=0.000) and the family income in Sobral (p=0.022). No statistically relevant differences were noticed between the two municipalities with regards to socio-demographic variables such as income, home floor type, basic sanitation and garbage collection. As for the HINT questionnaire directed to those responsible for looking after the children, in Fortaleza, 117 parents affirmed that they felt their baby was âstrong and firmâ, 88 of them stated that the childâs mobility was âexcellentâ and 85 reported that their children were âabove expected standardsâ when compared to others of the same age. In Sobral, 132 parents affirmed to feel their child to be âstrong and firmâ, 92 said their mobility was âexcellentâ and 87 said that the child was in ânormal development for his/her ageâ. The result of the neuromotor evaluation performance through the HINT program showed that most children, 98 (59.3%) in Fortaleza got a normal score and when evaluated through the Ministry of Health Control Protocol (Child Health Booklet) 127 (77%) in Fortaleza and 144 (87.3%) in Sobral were classified with adequate development. However, both instruments did not present a significant correlation between each other (K = -0.010). Despite this fact, both instruments proved to be useful for the target public, presenting advantages and disadvantages, which require further research with different samples and guidelines.

Short term incentive schemes for hospital managers

Malambe, Lucas 05 May 2014 (has links)
M.Com. (Business Management) / Introduction to the study Short-term incentives for managers generate interest among employees and executives in South Africa. In the health care industry competency-based performance systems for enhancing both individual and organisational performance have been growing in popularity in the last decade, as they are linked to the quality of diagnosis-specific services. Objectives of the study The objective of the study is to identify the nature of the main components of an appropriate short-term incentive scheme for private hospital managers. Are these schemes in place? If so, how do they work? The study seeks to delve into the experiences of hospital managers regarding their awareness of short-term incentive strategies by researching their views, attitudes and feelings regarding short-term incentives. Literature review The review of the literature indicates that the health care industry faces pressure to balance the quality of health care, on the one hand, with the escalating costs of health care and efforts to motivate hospital managers, on the other. Done correct ly short - term incent ive schemes are a powerful mot ivat ion tool if the intr insic and ext rinsic mot ivators are balanced adequately especially in a hospital set t ing where incor rect implementat ion can lead to unintended consequences. Research methodology The study utilises a qualitative strategy to provide an in-depth description of hospital managers‟ perceptions, understanding, and experiences of short-term incentives. The participatory approach reduces mistrust between subjects and researchers. Main findings The study found that the hospital managers are sharply aware and have a well developed understanding of the short-term incentives practiced in the private hospital sector. Short-term incentives may not be the major motivator but they are critical in ensuring that hospital managers stay motivated. Conclusion Providing a proper balance between intrinsic and extrinsic motivators is crucial in designing a framework that will keep hospital managers motivated and performing their work better.

Title: Extensibility Framework for a Generic Benchmarking Environment Type: Master thesis Author: Tadeáš Palusga Department: Department of Distributed and Dependable Systems Faculty of Mathematics and Physics Charles University Supervisor: RNDr. Andrej Podzimek, Ph.D. Department of Distributed and Dependable Systems Faculty of Mathematics and Physics Charles University Abstract: In 2004, at Faculty of Mathematics and Physics, Charles University, a project called BEEN (Benchmarking Environment) was introduced. The original aim of this project was to create a highly configurable and modular environment for middleware applications benchmarking. This project was successfully defended in 2007. In 2011, another group of students introduced a successor of this project called WillBEEN. Finally, in 2013 a project entitled EverBEEN, which was a complete reimplementation of the WillBEEN project, was successfully defended. The goal of the EverBEEN project was to bring newer technologies, asynchronous communication and stability improvements into the BEEN project family and resulted in a reimplementation from scratch. Despite all the effort, project EverBEEN remained tightly coupled with underlying libraries and technologies, contained a lot of generated code hard to maintain nor extend and last but not least the...

The development of a blasthole stemming performance evaluation model using a purpose built testing facility

Boshoff, Dawid 26 November 2009 (has links)
The ability of an explosive to break rock is influenced considerably by the extent of confinement in the blasthole and it is believed that confinement is improved by the use of stemming. The aim of this paper is to present the first and second stages of results in developing a stemming performance testing and evaluation facility for small diameter boreholes. The results showed that different stemming products have differences in terms of their functionality, which can have a major impact on the efficiency of rock breaking. Two test procedures were used, one through the exclusive use of compressed air and the second using a purpose built high pressure test rig with small quantities of explosives. Both tests were used to identify and evaluate the ability of various stemming products to resist the escape of explosive gas through the collar of a blasthole. Extensive research was conducted to determine the types of stemming products most commonly used in South African underground hard rock mines, and the differences in design between the various products are discussed. The first stage of tests using compressed air only did not prove adequate to predict with certainty the pressure behaviour in the borehole of a particular product under high pressure conditions. The purpose built high pressure test rig did not prove to be a very effective tool to test stemming products under high pressure conditions. The test rig only incorporated the effect of gas pressure on the stemming product and in doing so omitted to take the effect of the shock wave into account. This study proved that to only take the gas pressure generated in the blasthole into account in not sufficient to effectively test stemming product design. A more comprehensive study should include the effect of gas pressure in the borehole, shock waves generated by the explosive and also the coefficient of friction of both the surface of the stemming product as well as the inside of the blasthole. / Dissertation (MEng)--University of Pretoria, 2009. / Mining Engineering / unrestricted

A Model for Performance Evaluation of Emergency Department Physicians

Fiallos Rivera, Javier E. January 2014 (has links)
Performance of Emergency Department (ED) physicians (MDs) is multi-faceted since it impacts multiple dimensions such as health outcomes of patients, utilization of resources, throughput of patients and timeliness of care. Therefore, the assessment of their performance demands the use of a tool that allows considering multiple evaluation criteria. However, commonly used multi-criteria evaluation methods often require assigning weights to dimensions in order to define their relative importance on a final performance score. This feature introduces subjectivity in the development of weights and has the potential to produce biased results. The purpose of this thesis research is to develop a multi-dimensional evaluation tool for evaluating performance of ED MDs. The proposed evaluation tool relies on a mathematical programming model known as Data Envelopment Analysis (DEA). The use of DEA does not ask for subjective weighting assignments for each dimension that describe the ED MDs’ performance. It is capable of considering multiple heterogeneous performance measures to identify benchmark practice and the individual improvements leading to best practice of each evaluated unit. The DEA model described here was developed from real data to assess the performance of 20 PED MDs from the Children’s Hospital of Eastern Ontario (CHEO). Multiple evaluations were run on stratified data in order to identify benchmark practice in each of seven categories of patients’ complaints and to determine the impact of accompanying MD trainees on PED MDs’ performance. For each PED MD, performance scores and improvements in each category of patients’ complaints (i.e. respiratory, trauma, abdominal, fever, gastroenterology, allergy and Ear-Nose-Throat complaints) were determined. This helped identifying the required improvements that would lead PED MDs to achieve benchmark performance. Regarding the influence of MD trainees on PED MDs’ performance, results show that most PED MDs (15 out of 20) perform better when they are not accompanied by a trainee which motivates further research to assess trade-offs between teaching and clinical performance. In summary, DEA proved to be an appropriate tool for performance evaluation of PED MDs because it helped to identify benchmark performers and provided information for performance improvements under a multi dimensional performance evaluation framework.

Performance Evaluation of Cognitive Radios

Kaminski, Nicholas James 08 May 2012 (has links)
This thesis presents a performance evaluation system for cognitive radio. It considers performance as a complex, multi-dimensional function. Typically such a function would take some record of actions as an argument; however, a key contribution of this work is the addition of background information to the domain of the performance function. Including this information generalizes the performance function across many radios and applications, with the additional cost of complicating the domain. Thus the presented evaluation system organizes the domain information into sets. These sets are divided into two categories, one capturing necessary information that is external to the radio and on capturing necessary information that internal to the radio. These categories highlight the fact that neither the true actions nor the true performance is directly observable at the onset of evaluation. This arises because a cognitive radio can only express its actions in terms of the available knobs and meters, which together form the radio's language. Some understanding of this language and its limitations is required to fully understand the radio's expression of its actions. This parallelism of actions and performance suggests implementing the evaluation method as a composite form of the performance function. The composite performance function is made up of two sub-functions, one of which producing action information and one of which producing performance information. Specifically, the first sub-function is used to determine general measures of the actions' influence on performance; these are labeled Measures of Effectiveness. The second sub-function uses these Measures of Effectiveness to determine application specific performance values, called Measures of Performance. This work covers both these measures in detail. Each measure is determined as the result of a neural network based interpolation. This thesis also provides an examination of artificial neural networks in the scope of performance evaluation. Once these concepts are explored, a walk-through evaluation is presented. The four phases are the Setup Phase, the Logging Phase, the Training Phase, and the Evaluation Phase. Each phase is structured to provide the information necessary to determine the final performance. These phases detail the process of evaluation and discuss the realization of concepts explored earlier. This work concludes with a comparative evaluation example that proves the worth of the presented approach. A full evaluation system is outlined by this thesis and the foundational details for the system are explored in detail. / Master of Science

Video Streaming and Multimedia Broadcasting Over Vehicular Ad Hoc Networks

Naeimipoor, Farahnaz January 2013 (has links)
Video dissemination capabilities are crucial for the deployment of many services over VANETs. These services range from enhancing safety via the dissemination of video from the scene of an accident, to advertisement of local services or businesses. This work considers the infrastructure-less scenario of VANETs and dissemination of video content over this network environment, which is extremely challenging mainly due to its dynamic topology and stringent requirements for video streaming. This study discusses issues and challenges that need to be tackled for disseminating high-quality video over VANETs. Furthermore it surveys and analyzes the suitability of different existing solutions aimed towards effective and efficient techniques for video dissemination in vehicular networks. As a result, a set of the most promising techniques are selected, described in detail and evaluated based on standard terms in quality of service. This thesis also discusses efficiency and suitability of these techniques for video dissemination and compares their performance over the same network condition. In addition, a detailed study on the effect of network coding on video dissemination protocols has been conducted to guide how to employ this technique properly for video streaming over VANETs. From this study, a summary of the observations was obtained and used to design a new hybrid solution by deploying robust and efficient techniques in number of existing protocols in an optimal manner. The proposed hybrid video dissemination protocol outperforms other protocols in term of delivery ratio and complies with other quality-of-service requirements for video broadcasting over vehicular environments.

Ambivalent Sexism and Traditional Gender Roles as Predictors of Performance Evaluation Bias

Bragg, Caleb Braxton 09 July 2011 (has links) (PDF)
The object of the present research was to examine the relationship between ambivalent sexism, adherence to traditional gender roles, gendered job types, performance evaluations and promotion decisions. There were 124 participants recruited from undergraduate psychology courses, randomly assigned to one of four scenarios. Participants took the Ambivalent Sexism Inventory (ASI), Ambivalence towards Men Inventory (AMI), and Sex Role Egalitarianism Scale (SRES), read a scenario, and then evaluated the leader in the scenario using the Leadership Effectiveness Appraisal of Performance (LEAP). A 2x2x2 MANOVA found significant main effects for participant gender on the ASI and SRES, but no main or interaction effects were found for the other measures. Steiger's Z-test for “correlated correlations” in a sample did not find a significant relationship between the correlations in the different scenarios.
