The standard Chi-square test for the equality of proportions of positive responses to c specified binary questions is valid when the observed responses arise from independent random samples of units. When the responses to all c questions are recorded on the same unit, a situation called correlated proportions, the assumptions under which this test is derived are no longer valid. Under the additional assumption of compound symmetry, the Cochran-Q test is a valid test for the equality of proportions of positive responses. The purpose of this report is to use simulation to examine and compare the performance of the Cochran-Q test and the standard Chisquare test when testing for the equality of correlated proportions. It is found that the Cochran-Q test is superior to the Chi-square test in terms of size and power, especially when the common correlation among the binary responses is large.

Pełny tekst źródłaENGLISH ABSTRACT: The primary aim of the present study was to examine whether the culture of a society influences the way in which people justify certain aggressive behaviours in certain situations. A total of 756 students from Spain, Japan and South Africa participated in completing the CAMA, a measure of justification of aggression. The results showed that there were significant differences within the countries. There were differences in the levels of acceptance of certain acts between these countries. Further fmdings also indicated that there was a difference between the males of the countries and between the females of these countries. It was found that cultural influences and the norms within these countries bring about differences in justification of aggression in different situations. There were also some general trends of acceptance, with direct and indirect verbal acts e.g. sarcasm, hindering and shouting being more acceptable than physical acts such as hitting, killing and torture. It is hoped that the present findings of this research will make members of society more aware of their responsibility to help reduce aggressive acts by teaching and reinforcing norms against it. It is also hoped that the international community will gain better insight into the fact that South-Africa faces unique challenges because of the political and social changes in the country.
AFRIKAANSE OPSOMMING: Die primêre doel van die huidige studie was om vas te stelof 'n samelewing se kultuur 'n rol speel by die regverdiging van sekere aggressiewe gedrag in bepaalde omstandighede. 'n Totaal van 756 studente van Spanje, Japan en Suid Afrika het die CAMA vraelys voltooi. Die vraelys meet die regverdiging van aggressie in sekere omstandighede. Betekenisvolle verskille is tussen die lande gevind. Daar is ook betekenisvolle verskille tussen die mans van die drie lande asook tussen die vrouens van die drie lande gevind. Daar is gevind dat kulturele verskille en die norme binne 'n samelewing meebring dat daar verskille is in die mate waarin samelewings sekere aggressiewe gedrag aanvaarbaar vind in sekere situasies. Daar was ook 'n groter algemene aanvaarbaarheid van verbale aggressie bv. sarkasme, verhindering en skreeu as fisiese aggressie soos slaan, om dood te maak en marteling. Hopelik maak hierdie navorsing mense meer bewus van elkeen in die samelewing se verantwoordelikheid om die norme teen geweld te versterk asook om die norme aan hulle nageslagte oor te dra. Verder sal die internasionale gemeenskap hopelik beter insig kry oor die unieke uitdagings wat Suid-Afrika bied as gevolg van die politieke en sosiale veranderinge in die land.

Pełny tekst źródłaWith an explorative approach, this master thesis attempts to map associations and compare groupings of clients who have undergone an ASI Interview by The Swedish Prison and Probation Service, Kriminalvården. The study is based on 2 317 interviews carried out during the period 2008-2010, focusing on abuse of alcohol and narcotic substances. We will graphically illustrate interesting associations and study how the need for help varies throughout different areas of the respondents’ lives. Another aspect of this study is to evaluate the quality of the data material and to investigate non-response in the different variables. The quality of the material is fairly high and non-response is not extensive enough to affect analysis and inference. The errors found are almost exclusively due to how data is fed into the system. Since the majority of variables are qualitative, appropriate methods of analysis proved to be chi-square tests, correspondence analysis and association analysis. Most results confirm the existing image of an abusive personality, which has been presented in several studies before this one. A majority of the clients are men (85%) and the average age is 34 years. Interviewer estimates of the respondents’ need for help show that narcotic substances and criminal behavior are by far the greatest problem areas. The predominant drug is amphetamine (18%), followed by alcohol (15%) and cannabis (10%). We have established several significant differences between men and women, and between clients of different age groups. Young respondents show greater problems concerning criminal behavior, narcotic substances, work/providing and psychological health. With increased age we see enhanced difficulties regarding physical health and alcohol. Men more often exhibit problems concerning criminal behavior and narcotic substances, while women need increased help in areas of family/social life, physical health and psychological health.

Pełny tekst źródłaThe purpose of the study was to investigate the relationship between parental support and self-regulated learning behaviour of grade 12 learners. The study investigated support given to self-regulated learning of grade 12 learners. It gathered both quantitative and qualitative data. The researcher adopted the QUAN-qual model, which is also known as explanatory design. In this model quantitative data are collected first and are more heavily weighted than qualitative data. The quantitative method investigated the relationship between parental support and grade 12 learners’ self-regulated learning behaviour. It also investigated how parental support contributed to learner self-regulated learning behaviour. Qualitative research design explained strategies schools used to encourage positive parental support in their children’s self-regulated learning. It also explained why parents did not offer their support to their children’s education despite the fact that the South African School Act of 1996 encouraged them to do so. The population included grade 12 teachers and learners, as well as learners’ parents from different secondary schools in the Lejweleputswa district. The researcher administered questionnaires to 118 teachers and 218 learners, while 6 parents were interviewed. Teachers and learners were handed relevant questionnaires aimed at their level of participation in the survey. For quantitative data analysis the chi-square test was employed to test whether there were relationships between the variables. The study revealed that there was statistical significant relationship between parental support and learners’ self-regulated learning behaviour. Qualitative data was analysed making use of different analytical concepts used to guide researchers in qualitative data analysis. Although learners may acquire effective self-regulated learning strategies on their own, proper guidance from parents and teachers is very crucial, especially in the early stages of learning. The study established that regular general parent’s meetings, each term, help to facilitate improved learner performance. Amongst others, the researcher recommended that schools should introduce incentive for parental involvement in school matters.

Pełny tekst źródłaThe Birnbaum-Saunders regression model is commonly used in reliability studies.We address the issue of performing inference in this class of models when the number of observations is small. Our simulation results suggest that the likelihood ratio and score tests tend to be liberal when the sample size is small. We derive Bartlett and Bartlett-type correction factors which reduce the size distortion of the tests. Additionally, we also consider modified signed log-likelihood ratio statistics in this class of models. Finally, the asymptotic expansion of the distribution of the gradient test statistic is derived for a composite hypothesis under a sequence of Pitman alternative hypotheses converging to the null hypothesis at rate n^{-1/2}, n being the sample size. Comparisons of the local powers of the gradient, likelihood ratio, Wald and score tests reveal no uniform superiority property.

In the last decades the world has seen great dissemination of powerful brands, local and world-known, not infrequently assessed in billions of dollars, leading to massive sales of products and services associated with them. And in that context it is clear the impact of the intrinsic value of the intangible assets brand of companies in mergers and acquisitions.Nowadays, it has been clear that a Company valuation has a relevant amount related to intangible assets and, among these, brands have significant importance. This study aimed to investigate what is the general perception, the control method and the valuation of brands on companies operating in Brazil, by gathering information about the companies where students and recent graduates of post-graduate in business administration related courses used to work.Thus, from the sample group of 134 companies operating in Brazil, were extracted details of five dimensions of brand: awareness about its importance, financial valuation of the brand,accounting recognition of brand value, management of this intangible asset and its use as a tactical and strategic performance ratio. The methodology used was a survey that, from statistical tests Chi-square Pearson test led to the conclusion that there is no significant relationship between the fact that companies sell products and services and aspects relating to each of the five dimensions studied. Other variables statistically compared by using the chisquare test meant for the sample companies, among other findings, the significant correlation between large companies and the fact that companies evaluate brands or negotiate them. Also, the study took into account the criteria of attitude scores of respondents based on the Likert scale. The resulting data reveal that the brands are still in need of greater attention from companies. It is a minority in the sample studied the incidence of financial valuation of the brand, as well as the proper focus on accounting and management reports. Internal control over brand management and variable compensation system based on ratios of the brand,though present, such items were observed in low intensity in the sample companies.
Nas últimas décadas o mundo tem assistido à grande proliferação de marcas poderosas, local e mundialmente conhecidas, avaliadas não raramente em bilhões de dólares, levando a vendas em massa de produtos e serviços a elas associadas. E nesse contexto é notório o impacto do valor intrínseco do ativo intangível marca no valor das empresas em movimentos de fusões e aquisições. Hoje sabe-se que um valuation conta com parte relevante de seu montante relacionado a ativos intangíveis e, entre tais, as marcas possuem significativo destaque. Este trabalho objetivou investigar qual é a percepção geral, o método de controle e a avaliação das marcas em companhias em operação no Brasil, a partir de levantamento de informações sobre as empresas em que trabalhavam estudantes e recém egressos de cursos de pós-graduação profissional em áreas ligadas à administração de negócios. Assim, da amostra pesquisada de 134 companhias atuantes no país, foram extraídos detalhes de cinco dimensões da marca:percepção sobre sua importância, avaliação financeira, reconhecimento contábil de seu valor,gestão desse ativo intangível e de seu uso como indicador de performance tática e estratégica. A metodologia utilizada foi um levantamento (ou survey) que, a partir de testes estatísticos qui-quadrado de Pearson , permitiu a constatação de que não há relacionamento significativo entre o fato das empresas comercializarem produtos e serviços e aspectos ligados a cada uma das cinco dimensões estudadas. Outras variáveis comparadas estatisticamente pelo teste de qui-quadrado resultaram para as companhias da amostra, entre outras constatações, a significativa correlação entre as empresas de grande porte e o fato das empresas avaliarem marcas ou as negociarem. O estudo também levou em conta o critério de escores de atitudes dos respondentes baseado na escala Likert. Os dados resultantes revelam que as marcas carecem ainda de maior atenção por parte das empresas. É minoritária na amostra estudada a incidência de avaliação financeira da marca, assim como o devido enfoque em relatórios contábeis e gerenciais. Os controles internos de gestão da marca e o sistema de remuneração variável baseado em indicadores da marca, embora existam, mostraram-se itens pouco observados nas companhias da amostra.

Pełny tekst źródłaIn the first phase, the available technologies were identified, and the algorithms and the physical-mathematical models were defined for the positioning systems for both indoor and outdoor environments. The Dead Reckoning (DR) algorithm was included for this reason, because it can be applied in both environments. This algorithm allows the pedestrian's position to be obtained while s/he is walking. Given that one of the main parameters of DR is the pedestrian's step length, a careful analysis was carried out to determine it. Algorithms that allow, first, detection of a step and, second, calculation of its length are therefore presented here.
An integrated system based on UWB and inertial technologies (IMU) is proposed for indoor environments. This system uses the information about the step length to improve the information provided by the UWB system. The system that was defined for outdoor environments is a GPSIMU system based on the DR algorithm. Data fusion is carried out by means of Kalman filtering for both systems. In the GPSIMUDR system, the errors of the azimuth bias and the step length are obtained by means of Kalman filtering, which allows the DR parameters to be corrected and, consequently, the pedestrian's position can be obtained with greater accuracy.
In the next phase, the fault detection and correction methodology is developed. This is based on the principles of causal diagnosis using the theory of possibility. This methodology is proposed in order to prevent the introduction of erroneous information into the Kalman filter. In order to carry this out, failure states of the sensor systems are defined and corrective measures are applied when one or more of those states are present. These states are defined taking into account the empirical knowledge of the behaviour of the system. The performance of the filters was also monitored. This consists in the continuous evaluation of their innovations and, in case of inconsistency, corrective measures are applied to the parameters of the filters.
The experiments, for the proposed systems, presented results that improved their initial response to a considerable degree. For the UWBIMU system, an analysis that involves the detection of inconsistencies of the filter is presented, while for the GPSIMUDR system the fault detection and correction methodology is applied. In the UWBIMU system, the corrective measures introduced into to the Kalman filter allowed both consistent filtering and a soft signal to be obtained, i.e. most of the reflections of the signal provided by the UWB system were eliminated. The results of the GPSIMUDR system indicated that by implementing the methodology developed here, consistent filtering was obtained and the values of the azimuth and the step length were corrected properly. As a result more exact pedestrian trajectories were obtained.

Despite the belief in the link between quality, customer satisfaction and economic returns, we need to learn more about this area. The propose of this study is to evaluate customer satisfaction of new buildings in the city of Curitiba. To get the data, we conducted a preliminary study and a quantitative survey. The first step searched for information to the construction and validation of the questionnaire used in the second part, which was destined to final customer. We obtained 386 questionnaires during March to November 2013. And through descriptive data analysis, we found that sample is true to the universe studied, because there are not significant differences. To perform the analysis of the sample, we considered the approach defined by the authors Hair et al. (2010), where a model of customer satisfaction is completely understood only when we studied: the variable, constructs, and relationships between two or more variables. Therefore, we performed several descriptive analyzes and the chi-square test in order to study the variable components of satisfaction. Next the constructs, which were obtained from through factor analysis. And last, we check the relationship between variables through multiple linear regressions of the data. As a result of this work, we noticed that it is not possible to rely only on the average overall satisfaction, because it may mask other results. In addition, we found that the variables: the default of the building and type of management (with or without TQM), can influence customer satisfaction. For example, participants of buildings built without TQM are more satisfied than those built with TQM, and the group of participants of buildings of low default is the most unhappy of all the defaults. Through factor analysis, we found four factors, communication with the company, product, location, design, as well as a general factor, overall satisfaction. The dissatisfaction is evident in the two most important factors: communication with the company and product. It is believed that, although our study is valid only for Curitiba, the development and structure of this model provide a great reference for the evaluation of customer satisfaction in other settings of the construction industry.
