Christensen, Cristina. "Performance measures and subjective evaluations for two color displays." Thesis, Virginia Tech, 1985. http://hdl.handle.net/10919/45714.
Full textAbstract:
The current study investigated the task performance and subjective preference for two color displays with differing image generation technologies, the standard cathode ray tube shadow mask (CRT) display and the newer liquid crystal/cathode ray tube (LC/CRT) display. Six subjects performed three different information processing tasks using each of the two color display technologies and expressed their display preference via evaluation questionnaires. Ambient illumination measurements were obtained to determine preferred conditions for each display.
A four-way factorial design was used to collect task performance data and ambient illumination preferences; performance data were collected as errors per unit task quantity for each of the task types. Subjective evaluations consisted of 20 five-interval bipolar adjective scales and a forced choice rating on eight display parameters. An analysis of variance procedure and post-hoc Newman-Keuls analyses were employed in the analyses of the performance and subjective bipolar adjective scale data; the forced choice rating scales were evaluated using the Sign Test.
The task performance results indicate that neither display produced better task performance. The subjective data revealed mixed results; while the bipolar adjective scales indicate no differences between the two display technologies, the forced choice rating shows a preference for the LC/CRT display on some display parameters.
A significant difference between the two displays was demonstrated for ambient illumination preferences; the LC/CRT was viewed in greater ambient illumination than the CRT display.Master of Science

Full textAbstract:
The purpose of this study was to examine the effects of a music-assisted relaxation training program as a treatment method for college music students suffering from performance anxiety. A total of 40 participants were randomly assigned to the experimental (n=20) and wait-list control (n=20) groups. The experimental group received six music-assisted relaxation training sessions while the wait-list control group received no contact. Dependent measures included pre- and post-test State Trait Anxiety Inventory (ST AI) scores and heart rate measurements during individual jury examinations (performance condition).
Results found no differences in ST AI scores and heart rate measurements between groups. Factors such as years of formal training and memorization of performance showed no differences in dependent measures. The experimental group rated their performance quality as significantly higher than the wait-list control group.
All participants who received the relaxation training program felt they benefited from it, and_ found it helpful in feeling more "in control" and "focused on their music" during performances.

Full textAbstract:
The research objective was to develop, through two phases involving development and validation, a measure of the psychological work contract for managerial level employees. The psychological contract is the unwritten implicit contract that forms in the minds of employees and contains the obligations and expectations that they believe exists between themselves and the organization. In the first and qualitative phase of the study, a structured interview procedure resulted in the collection of 651 responses from a convenience sample of 35 managers from seven New Zealand organizations. Responses related to what these managers believed they were obligated to provide the organization (perceived organizational expectations), and what they believed the organization was obligated to provide them (their expectations). Content analysis of these 651 statements resulted in the development of two initial measures of the psychological contract (employee obligations, organization obligations). The employee obligations measure (perceived organizational expectations of the employee) contained 16 items, and the organization obligations measure (employee expectations of the organization) contained 23 items. In the second and quantitative phase of the study, and using the same criteria for participation as for phase one, a convenience sample of 124 managers from 13 New Zealand organizations completed questionnaires. The questionnaires included the measures of psychological contract content developed in phase one of the study, and 8 organizational psychology variables to be included in a nomological network. The nomological network included intention to quit, perceived organizational support, work and job involvement, job satisfaction, career plateau, organizational commitment, person-organization fit, and 2 performance measures. A separate questionnaire covering job performance and organizational citizenship behaviour was completed by 94 of the participants' managers. Of the 54 relationships predicted in the nomological network, 41 were significant. Of the 13 non-significant relationships, 10 involved relationships with the two performance measures. The measures of the psychological contract were subjected to a construct validation process involving two steps. The first step involved item and factor analysis. Factor analysis of the two measures of the psychological contract revealed two factors in each. One factor, termed relational obligations and reflecting a collective interest between the employee and the organization, included the items that were believed to influence more directly the relationship between managers and the organization. This factor included items such as be committed to the job (an employee obligation) and provide a physically and socially safe environment (an organizational obligation). The other factor, termed transactional obligations and reflecting a self/other interest on the part of the employee, included the items that were believed to be of a more direct employment transactions nature. This factor included items such as stay true to your own values and beliefs (an employee obligation) and provide professional and personal support (an organizational obligation). In the second step of the validation process, the measures of the psychological contract were embedded into the nomological network and their relationships with the ten variables in that network were tested. Of the ten hypothesised relationships, only one emerged as significant, that being the relationship between the organization obligations component of the psychological contract and person-organization fit. Minimal support for construct validity of the measures of the psychological contract was provided confirming that further effort will be required before complete construct validity may be claimed for the measured. Although the contribution the research makes to the field of knowledge may be limited, it does provide some validation of existing measures of the psychological contract, developed in other studies using different samples. The present findings increase our knowledge of the content of the psychological contract for managers. Additionally, a methodological framework has been established for continuing research into the content of psychological contracts, including an exploration of the relationship between content and fulfilment, along with a structure for comparing the psychological contract of disparate occupational groups. The most likely explanation for the hypotheses not being fully supported is that it is fulfilment (or conversely breach or violation) of the psychological contract, rather than the content of the contract per se, that is related to the variables in the nomological network. Whilst the hypotheses were based on research that considered fulfilment of the contract, this study focussed on the content of psychological contracts. The reasons for basing the hypotheses on research that considered fulfilment, the influence of this decision on hypothesis testing, and other possible explanations for the hypotheses not finding greater support, are explored. The limitations of the study, and possible directions for future research, are discussed.

Full textAbstract:
Service orientation has been suggested to be a work-related behavioral trait that contributes toward overall job performance in certain occupations. Therefore, the Batrus Hollweg Service Questionnaire (SQ), a personality inventory, was hypothesized to predict performance in a sample (N=55) of fast-food restaurant workers whose jobs were primarily composed of service-related elements. A performance evaluation form was created for use as the criterion measure. An alternative scoring system for the SQ was developed, and showed it to be significantly correlated with the criterion. The potential for use of the alternative scoring procedure is discussed.

Full textAbstract:
The scores or metrics from psychological measures are rarely interpretable. Uninterpretable metrics result in poorly understood psychological research findings. In response to this problem, several methods are proposed that render metrics more meaningful. The methods employed are calibration procedures. Three calibration procedures are illustrated that prove to be extremely powerful in making the metrics of two related measures more understandable. Establishing the behavioral implications of the scores, computing just noticeable differences, and calibrating between measures are the three procedures described and illustrated. For the purposes of illustration, two measures of Attention Deficit Hyperactivity Disorder (ADHD) are used in the calibration procedures. These two measures are often used interchangeably without regard to their relationship with one another. The three procedures and the results of each are discussed in detail.

Full textAbstract:
Thesis (PhD (Economics))--University of Stellenbosch, 2008.The primary financial objective of a firm is the maximisation of its shareholders’ value. A problem faced by the shareholders of a firm is that it is difficult to determine the effect of management decisions on the future share returns of the firm. Furthermore, it may be necessary to implement certain monitoring costs to ensure that management is focused on achieving this objective. A firm would, therefore, benefit from being able to identify those financial performance measures that are able to link the financial performance of the firm to its share returns. Implementing such a financial performance measure in the valuation and reward systems of a firm should ensure that management is aligned with the objective of shareholder value maximisation, and rewarded for achieving it. A large number of traditional financial performance measures have been developed. These measures are often criticised for excluding a firm’s cost of capital, and are considered inappropriate to be used when evaluating value creation. Furthermore, it is argued that these measures are based on accounting information, which could be distorted by Generally Accepted Accounting Practice (GAAP). Studies investigating the relationship between these measures and share returns also provide conflicting results. As a result of the perceived limitations of traditional measures, value based financial performance measures were developed. The major difference between the traditional and value based measures is that the value based measures include a firm’s cost of capital in their calculation. They also attempt to remove some of the accounting distortions resulting from GAAP. Proponents of the value based measures present these measures as a major improvement over the traditional financial performance measures and report high levels of correlation between the measures and share returns. A number of studies containing contradictory results have been published. On the basis of these conflicting results it is not clear whether the value based measures are able to outperform the traditional financial performance measures in explaining share returns. The primary objectives of this study are thus to: • Determine the relationship between the traditional measures earnings before extraordinary items (EBEI) and cash from operations (CFO), and shareholder value creation; • Investigate the value based measures residual income (RI), economic value added (EVA), cash value added (CVA) and cash flow return on investments (CFROI), and to determine their relationship with the creation of shareholder value; • Evaluate the incremental information content of the value based measures above the traditional measures. The information content of the traditional measures and the value based measures are evaluated by employing an approach developed by Biddle, Bowen and Wallace (1997). The first phase of this approach entails the evaluation of the relative information content of the various measures in order to determine which measure explains the largest portion of a firm’s market-adjusted share returns. The second phase consists of an evaluation of the incremental information content of the components of a measure in order to determine whether the inclusion of an additional component contributes statistically significant additional information beyond that contained in the other components. The study is conducted for South African industrial firms listed on the Johannesburg Securities Exchange for the period 1991 to 2005. The data required to calculate the measures investigated in the study are obtained from the McGregor BFA database. This database contains annual standardised financial statements for listed and delisted South African firms. It also contains EVA, cost of capital and invested capital amounts for those firms listed at the end of the research period. Including only these listed firms in the research sample would expose the study to a survivorship bias. Hence these values are estimated for those firms that delisted during the period under review by employing a similar approach to the one used in the database. The resulting sample consists of 364 firms providing 3181 complete observations. Since different information is required to calculate the various measures included in the study, different samples are compiled from this initial sample and included in the tests conducted to evaluate the information content of the measures. The results of this study indicate that the value based measures are not able to outperform EBEI in the majority of the relative information content tests. Furthermore, the measures EVA, CVA and CFROI are also not able to outperform the relatively simple value based measure RI. The results from the incremental information content tests indicate that although some of the components of the value based measures provide statistically significant incremental information content, the level of significance for these relatively complex adjustments is generally low. Based on these results, the claims made by the proponents of the value based measures cannot be supported. Furthermore, if a firm intends to incorporate its cost of capital in its financial performance measures, the measure RI provides most of the benefits contained in the other more complex value based measures.

Full textAbstract:
The present study investigated deaf children's performance on several modified tests of the original Halstead Reitan Neuropsychological Battery for Older Children (HRNB-C). Specifically, performance of 42 deaf children (mean age = 13.3 years, SD = 0.7 yrs.) and a matched sample of 42 hearing peers was examined on the HRNB-C Category, Tactual Performance, and Trail Making tests.In Study 1, a computerized version of the Category Test was administered. Step-down F tests were used to examine differences in total errors and the unique contribution of response time. In Study 2, the Tactual Performance and Trail Making scores were dependent variables. Logistic regression analysis was used to explore multivariate intergroup differences.The major finding of this research was that neuropsychological abilities of deaf children who have no additional handicapping conditions or impairments are, in general, similar to matched hearing controls. Few clinically relevant differences were found. No quantitative differences were found on Trail Making Part A or the total number of Category Test errors. Noteworthy, from a qualitative stance, was the role of response time and its unique contribution within the Category Test. Deaf subjects had significantly greater response times to individual items regardless of correctness of answer. Deaf children were also found to take longer on Trails B, although they performed within normals limits. With respect to the Tactual Performance Test (TPT), deaf children did slightly better than their matched hearing peers on TPT total time and location. In addition, Trails B and TPT location scores were the best multivariate composite of discriminators of deaf versus hearing performance. Notwithstanding, overinterpretation of statistical differences found in both studies was cautioned and the similarities of performance between deaf and hearing children emphasized.These findings offered information of deaf children's neuropsychological functioning compared to hearing controls in the clinical setting. Moreover, the results of the present study should be generalizable to other "non-impaired", 12-14 year old deaf children within a residential academic environment.Department of Educational Psychology

Full textAbstract:
Performance management is a vital part of every organization for its success and long term survival in the current competitive global market place. An organization needs a sound performance management framework to analyze its data to make strategic and tactical decisions. The weaknesses in today's performance management frameworks are linked to their inability to integrate strategy formulation with implementation.
In our thesis, we introduce D river Measure Models that can define cause-and-effect relationship between d river measures and Key Performance Indicators (KPIs) for effective performance management and strategic alignment. Driver Measure Models make the performance management more dynamic as the operational activities are linked to strategies.
Another contribution of the thesis is the identification of mathematical techniques to quantify relationships between KPIs and driver measures. Thesis makes an effort to show how mathematical techniques can be used for planning and forecasting outcomes while changing strategies. After conducting analysis using the mathematical techniques, organization can arrive at a set of operational tasks associated to driver measures which need to be executed to achieve its optimal result.
Finally, we identified the essential set of criteria that a performance management framework needs to address through a literature survey and a gap analysis of existing frameworks. We created an extension to the Balanced Scorecard framework based on Driver Measure Models and support for the management of external factors to address these criteria and compared it to existing frameworks using a case study.

Dissertação para obtenção do Grau de Mestre em
Engenharia e Gestão IndustrialIn the existing global economic context it is crucial that companies understand the importance of the supply chain, so that they can maintain their respective competitive advantage. Several of the supply chain’s approaches consider the customer and the definition of value as key features. One easily associates the Lean philosophy to supply chains, with its basis of continuous improvement and elimination of waste. Companies which employ this philosophy begin with lean thinking, which highlights the customer and the definition of value. Therefore it is vital that companies identify what constitutes added value to the customer. Thus we arrive at the reasons which have led to the creation of this dissertation. The motivation concerns the small amount of data found upon reviewing the existing literature of the application of Lean philosophy to the Wood-Plastic Composite Industry (WPC). Consequently the study’s main goal is the identification of Lean performance measures. This dissertation contains concepts of Lean philosophy and strategy to provide background for its practical part, after which, we explain the applied methodology: identification of the performance measures, application of strategy analysis tools, the development of a survey and its statistical treatment and finally interviews to management. The results of the surveys have provided results which have helped identify the most important categories: time and flexibility; and the most relevant performance measures. The interviews’ results provided input on management’s knowledge and expectations of Lean, and the discovery of possible areas for improvement. The major conclusion of this study is the importance given to Lean performance measures in the WPC industry’s context, which can help in the implementation of Lean.

Full textAbstract:
L'analyse de la performance à l'état stationnaire dans de nombreux systèmes de files d'attente est complexe et les résultats sous forme explicite ne sont disponibles que dans des cas particuliers. Nous avons donc développé des approximations pour des critères de performance importants à l'état stationnaire tels que la longueur de la file d'attente, le temps d'attente et le temps de traitement total. Nous analysons d'abord la performance dans des cas à faible et fort trafic. Nous montrons ensuite comment développer une approximation basée sur une interpolation qui est valable pour n'importe quelle condition de trafic. Un avantage de l'approche proposée est qu'elle n'est pas dépendante d’un modèle particulier et donc elle peut être appliquée à d'autres modèles de files d'attente complexes. Nous appliquons cette technique pour trois modèles largement utilisés dans l'évaluation des performances des réseaux stochastiques : le modèle du supermarché, la file d'attente Discriminatory-Processor-Sharing (DPS) et la file d'attente Relative Priority (RP). Le modèle du supermarché est une file d'attente à plusieurs serveurs où lorsqu’un client arrive, deux serveurs sont choisis au hasard dans un ensemble de serveurs. La politique Join-the-Shortest-Queue (JSQ) est ensuite utilisée parmi les deux serveurs sélectionnés. DPS et RP sont deux files d'attente à plusieurs classes et à serveur unique mettant en œuvre des priorités relatives entre les clients des différentes classes. La discipline DPS sert tous les clients simultanément, tandis que RP sert un seul client à la fois de manière non-préemptive. Nous montrons que dans certains cas, l'interpolation est exacte. Nous utilisons ensuite cette approximation pour déduire comment la performance dépend des paramètres des modèles, et nous effectuons des expériences numériques illustrant la précision de l'interpolation dans un grand nombre de cas de figureThe analysis of the steady-state performance in many queuing systems is complex and closed-form results are available only in particular cases. We therefore set out to develop approximations for important performance measures in steady-state such as the queue length vector, waiting time and sojourn time. We first analyse the performance in a light-traffic and heavy-traffic regime. We then show how to develop an interpolation-based approximation that is valid for any load in the system. An advantage of the approach taken is that it is not model dependent and hence could potentially be applied to other complex queuing models. We apply this technique to three widely used models in the performance evaluation of stochastic networks: The supermarket model, the Discriminatory-Processor-Sharing (DPS) queue and the Relative Priority (RP) queue. The supermarket model is a multi-server queue where upon arrival of a customer two servers are selected at random from the available pool of servers. The Join-the-Shortest-Queue policy is then used in isolation with these two servers. DPS and RP are both single-server multi-class queues that implement relative priorities among customers of the various classes. The DPS discipline serves all customers simultaneously while RP serves one customer at a time in a non-preemptive way. We show that in some instances the interpolation approximation is exact. We then use the approximation to draw structural insights onto the performance of the system, and we carry out numerical experiments that illustrate that the interpolation approximation is accurate over a wide range of parameters

Full textAbstract:
Emergency medical services (EMS) have been of interest for operations research since the middle of the 1960‘s. Since then there have been published numerous articles on the location of ambulances stations, allocation of ambulances, dispatching of vehicles, re-deployment of ambulances and evaluation methods. This thesis presents a new problem for the location of ambulance stations and allocation of ambulances in heterogeneous regions, referred to as the Maximum Expected Performance Location Problem for Heterogeneous Regions (MEPLP-HR). The problem applies multiple performance measures as well as station specific probabilities for the availability of ambulances at a station. Compared with earlier problems, the MEPLP-HR is more realistic for heterogeneous regions as the service rate of ambulances in the problem depends on the area a station covers. A mixed integer linear model is proposed to solve the problem. The probability for available ambulances is found by utilizing queuing theory together with the service rate and arrival rate of calls for each station. In contrast to recent models, the probability for available ambulances is calculated within the model. Hence, it is not necessary to use iterative solution approaches. The formulation is strengthened using valid inequalities and a reformulation of a restriction. With the strengthening constraints, both the solutions and the best bounds are improved.The computational studies are performed on the heterogeneous region of Sør-Trøndelag in Norway. For this region, the model is able to find a realistic solution that has a higher expected performance than the current solution on each of the given performance measures. The model is also tested with different weights for the performance measures, with the conclusion that the weights significantly affect the locations and allocation of stations and ambulances. By using the model as a decision support tool, three real managerial cases are analyzed together with potential solutions. The first case concerns the importance of taking multiple time periods into account when planning. The results from the computational study indicate that it is sufficient to plan for the busiest period. The second case analyzes the consequences and potential mitigating actions for closing down a local emergency room (ER). By closing the local ER, the travel time to ER will increase significantly for the zones close to the local ER. However, adding an extra ambulance and ambulance station can to some degree mitigate this effect. The third case concerns the benefit of transferring all non-urgent transport calls to designated non-urgent transport vehicles. The analysis in this case shows that there is a potential to reduce the number of ambulances by one fifth if designated non-urgent vehicles are introduced.This thesis consists of a report and two articles. The report is the main part of the thesis and contains all of our results and analyses. The articles are found as separate works after the report. The first one, "Strategic ambulance location for heterogeneous regions", presents the problem, the proposed model and technical characteristics. The second article, "Strategic Emergency Medical Service Planning - Three Case Studies", presents how the model can be applied as a decision support tool. The articles are based on the report, hence the report and articles are to some degrees overlapping.

Full textAbstract:
The present thesis examines two central issues in financial theory, optimal portfolio choice and investment performance evaluation, when the restrictive assumptions of the traditional static, mean-variance framework of analysis are relaxed. Chapter 2 presents a series of model specifications for the risky asset's returns and the underlying risk factor and derives the corresponding optimal portfolio choices. It shows how important the modelling assumptions are for the implementation of dynamic asset allocation in practice and it contributes to the literature by examining the impact of horizon effects on portfolio choice in the presence of both predictability and stochastic volatility in asset returns. Moreover, this chapter shows how important is the introduction of an asset that completes the market and allows investors to hedge against the shocks that affect their opportunity set, Chapter 3 examines the bond portfolio choice of a long-term investor, making use of a macro-finance term structure model that allows for time-varying risk premia. This chapter shows how important is the failure of the expectations hypothesis for both myopic and long-term investors, since the time-variation in the bond premia dictates a market timing behaviour for investment as well as for hedging purposes. Incorporating macroeconomic information, that plays a significant role in bond pricing, we examine how this can be used for the formation of optimal portfolios by long-term investors. Furthermore, this chapter serves as an evaluation of the very recent term structure models from an asset allocation perspective, drawing the attention to the correlation and the covariance structure of the bond returns. Chapter 4 employs the Harvey-Siddique asset pricing model and evaluates a sample of UK equity unit trusts, proposing the intercept of this model, that is termed as the Harvey-Siddique alpha, as a new performance measure. This asset pricing model adds to the CAPM the returns of a negative coskewness strategy as an extra risk factor. Constructing this factor for the UK stock market, it is shown that negative coskewness bears a high risk premium. This framework allows us to examine how the adoption of specific performance measures generates incentives in fund management. In particular, we provide evidence that fund managers, who are evaluated by mean-variance performance measures, are incentivized to load negative coskewness risk to their portfolios in order to reap the corresponding premium and present it as outperformance. Chapter 5 overviews the contributions of this thesis, discusses the numerous issues that arise from the present results and outlines the following steps in our research agenda.

Mestrado em FinançasCorporate Governance é um dos temas com maior interesse público pela importância demonstrada para a saúde económica das empresas e da sociedade em geral. A importância dele baseia-se principalmente pelo estabelecimento de regras que definem as relações entre os gestores, accionistas e membros de conselho de administração. Esta tese tem como objetivo investigar a relação entre desempenho da empresa e corporate governance das 62 empresas espanholas selecionadas da Bolsa de Madrid no intervalo de tempo entre 2005 e 2012. Neste estudo foram usados três tipos de variáveis de desempenho, Financeiro (Retorno de Capital), de Mercado (Retorno das Acções) e Operacional (Retorno dos Ativos). Para o efeito utilizou-se um modelo de regressão linear com dados em painel. No final deste estudo concluímos que variáveis de Corporate Governance tais como: concentração de accionista, número de membros no conselho de administração, número de membros independentes têm forte impacto sobre o desempenho da empresa.
Corporate governance has been one of the subjects with a strong public interest because of its apparent importance for the economic health of corporations and society in general. His importance sets especially on definition of the relationship be-tween management, board directors and shareholders. This study researches the relationships among firm performance and the corpo-rate governance measures for 62 Spanish firms between 2005 and 2012. We use three types of firm performance variables, the Financial (Return on Equity), the Market (Stock Return) and the Operating (Return on Assets). For this purpose we have used a linear regression model with panel data. This analysis led to the conclusion of those corporate governance variables like shareholder concentration, number of independent board members and number of board members have strong influence on the firm.

Mestrado em FinançasO objetivo deste estudo é analisar algumas medidas de governo de sociedades, em especial variáveis de composição do conselho de administração, e a sua relação com a performance da empresa. Através de uma amostra de empresas francesas do Índice bolsista SBF120 pertencente à NYSE Euronext, foi possível construir uma base de dados de painel, desde 2005 a 2012, com 71 empresas e 10 variáveis. Os três indicadores usados para avaliar a performance das empresas, ROE, ROA e Tobin´s Q apresentaram resultados significativos em relação à existência de uma associação negativa entre a independência dos membros do conselho de administração e a performance da empresa o que corrobora a hipótese em estudo. Em relação à presença de mulheres no conselho de administração os resultados são contrários à hipótese formulada, constatando uma associação negativa com o ROE e o Tobin´s Q. A hipótese que relaciona negativamente o tamanho do conselho de administração com a performance da empresa apresentou resultados divergentes, o que não permite apresentar conclusões sustentadas.
The aim of this study is to analyze some measures of corporate governance, especially board composition variables, and their relation with firm performance. Given a sample of French companies of the SBF120 Index belonging to NYSE Euronext, it was possible to build a panel database, from 2005-2012, with 71 companies, and 10 variables. The three proxies used for firm performance, ROE, ROA and Tobin´s Q presented significant results regarding the existence of a negative association between board independence and firm performance and the hypothesis in study was corroborated. Regarding the presence of female board members the results went against the formulated hypothesis, finding a negative association with ROE and Tobin´s Q. The hypothesis that relates the board size with firm performance has presented mixed findings, so a conclusion is not consistent.

Full textAbstract:
The aims of this research are: (A) to examine current practices in executive performance measures in manufacturing; and (B) to propose a model for executive performance measures that reflects both the aspirations of practitioners and the issues raised in academic literature. Executives in the context of this research are defined as the leaders of their organizations who "exercise strategic management not only via the more obvious dimensions of analysis, policy formulation, evaluation and planning but also in their behaviour" (Burke, 1986:64). So executive performance is considered in terms of the roles and responsibilities of executives as leaders, their strategic objectives and their behaviours. The purpose of executive performance measures is to provide an improved understanding of the issues of executive performance. A holistic approach is taken in this research in exploring executive performance measures by addressing the following questions: What are the executive roles and responsibilities in practice? What are the strategic objectives of executives in practice? What are the desired behaviours of executives in practice? What current executive performance measures are used in practice? In the light of these questions, is it possible to create a model for executiveperformance measures? The fieldwork was conducted in three medium sized manufacturing companies using a qualitative case study approach that included direct observation in the form of workshadowing (Mintzberg, 1973), repertory grid technique (Gammack and Stephens, 1994) and semi-structured interviews. The main findings from the fieldwork are that the current practices in executive performance measures in manufacturing organizations favour measures for performance output, particularly in relation to the financial and internal business process perspectives. By contrast the executives themselves feel the practical need for measures, which include executive behaviours alongside the performance output measures. The principal contribution of this research is a model for considering measures for executive performance outputs together with measures for executive behaviours in achieving those outputs. This model (which goes further than any previous model in the field) will allow its users to consider measures to improve executive performance. The aim is that any improvement in the executive performance will contribute to the improved performance and competitive position of their organization.

Clusters of low-performance spacecraft flying in formation may
provide enhanced performance over single high-performance
spacecraft. This is especially true for remote sensing missions
where interferometry or stereographic imaging may provide higher
resolution data. The configurations of such formations vary
during an orbit due to orbital dynamics, and over longer time
scales due to perturbations. Selection of a configuration should
be based on overall performance of the formation. In this thesis,
performance measures are developed and evaluated based on
integration over one orbit. The measures involve the angular
separation of spacecraft, the distance between spacecraft, and an
area-based measure of the separation of the spacecraft. Numerical
techniques are employed to evaluate the performance measures to
determine optimal scenarios for two formations. Simplifying
assumptions are made to allow a closed-form analytic solution and
the results are compared to those obtained numerically. Finally,
the sensitivity of the measures to linearized propagation
techniques is investigated.Master of Science

This thesis investigates which factors that affect the salary for basketball players in the NBA and if the salary cap has achieved its purpose. The data for this project was collected from basketball-reference.com and consisted of performance measures from season 2015/2016 and salaries from the beginning of the season 2016/2017. The study was performed by using multiple linear regression analysis in the software R and the data was handled in Excel. The results from the regression indicates that position point guard, if the player has played in D-league or not,Age, Offensive rebounds, Assists, Steals, Two point attempts, Three point attempts, Free throw attempts, Field goal percentage, Usage percentage and Defensive rating are the main factors that affect the salary. The performance measures that had the greatest were two and three point attempts. The regression model achieved an explanatory level of 57:4%. In complementary to analyze if the salary cap has achieved its purpose, a literature analysis was used and showed that the salary cap systems in North America are neither accurately designed nor do they satisfy the intentions of what they were set to achieve.Denna rapport undersöker vilka prestationsfaktorer som påverkar lönen för basketspelare i NBA och om NBA’s salary cap (lönetak) har uppnått sitt syfte. Datan för projektet hämtades från basketball-reference.com och bestod utav spelarstatistik ifrån säsong 2015/2016 och lön ifrån början av säsong 2016/2017. Undersökningen utfördes genom linjär regressions analys med hjälp utav mjukvaruprogrammet R och datan hanterades i Excel. Resultatet från regressionen visar att positionen point guard, om spelaren spelat i D-league eller inte, ålder, offensiva returer, assists, steals, 2-poängsförsök, 3-poängsförsök, straffkastsförsök, field goal procent, användningsprocent och defensiv rating är faktorer som påverkar lönesättningen. Prestationsmåtten med störst påverkan var 2-poängsförsök och 3-poängsförsök. Regressionsmodellen uppnådde en förklaringsgrad på 57:4%. Motsvarande, för att analysera om NBA’s salary cap har uppnått sitt syfte gjordes en litteraturstudie som visade att salary cap-systemen i Nordamerika varken är korrekt utformade eller uppfyller sina ursprungliga syften.

Full textAbstract:
There is no widely accepted tool to assess an orthopedic surgeon’s technical skill in the operating room. With changes in surgical education, simulators are being investigated for learning and assessing technical skills, but a link between the actual operating room is needed to ensure they are effective. Hip fracture surgery is a good starting point to develop these measures because hip fractures are common and fixation is a difficult task.
Resident orthopedic surgeons wore a head-mounted video camera during hip fracture surgery. Data collected included: duration, number of x-ray images, the supervising surgeon intervention, and tip-apex distance (TAD, a measure of how accurate the implant is placed). To determine the reliability of these measurements, four raters performed them for two cases. Ten raters measured the tip-apex distance (TAD) on 7 cases. These performance metrics for 15 cases were compared to experience of the residents, both point in residency and number of previous cases. A composite performance score was computed using the four metrics. The metrics were also compared to two practicing surgeons’ assessment of skill.
The inter-rater reliability of the performance metrics was high (0.97-0.99) showing these measures are consistent between different raters and useful for assessment. There was a significant relationship between resident experience and the metrics of duration and TAD. Expert opinion was related to duration.
These metrics provide objective assessment of resident technical performance in the operating room by a non-expert, an important step towards competency based education. Their validity is shown with correlation to surgical experience.

Full textAbstract:
An ensemble is a composite model, aggregating multiple base models into one predictive model. An ensemble prediction, consequently, is a function of all included base models. Both theory and a wealth of empirical studies have established that ensembles are generally more accurate than single predictive models. The main motivation for using ensembles is the fact that combining several models will eliminate uncorrelated base classifier errors. This reasoning, however, requires the base classifiers to commit their errors on different instances – clearly there is no point in combining identical models. Informally, the key term diversity means that the base classifiers commit their errors independently of each other. The problem addressed in this thesis is how to maximize ensemble performance by analyzing how diversity can be utilized when creating ensembles. A series of studies, addressing different facets of the question, is presented. The results show that ensemble accuracy and the diversity measure difficulty are the two individually best measures to use as optimization criterion when selecting ensemble members. However, the results further suggest that combinations of several measures are most often better as optimization criteria than single measures. A novel method to find a useful combination of measures is proposed in the end. Furthermore, the results show that it is very difficult to estimate predictive performance on unseen data based on results achieved with available data. Finally, it is also shown that implicit diversity achieved by varied ANN architecture or by using resampling of features is beneficial for ensemble performance.Sponsorship:

The current study evaluated the reliability and validity of psychological flexibility self-report measures between typically developing under 18 and over 18 aged individuals. An independent samples t test with a correlational statistical analysis was conducted to evaluate the relationship between the CPFQ, CAMM, AFQY and AAQII. The results demonstrated that three out of four measures are reliable and valid in determining psychological flexibility between the two groups. This study adds to literature that is conducive in the analysis of measures that are designed for younger population to be utilized by practitioners with older populations reliably.

Orlando, Ronniet. "Comparing live to recorded music and stories using multiple psychoneuroendocrine and psychological measures." Thesis, Edith Cowan University, Research Online, Perth, Western Australia, 2018. https://ro.ecu.edu.au/theses/2136.
Full textAbstract:
Listening to music brings health benefits, according to an expanding opus of empirical research. Studies to date cover a wide range of music interventions and outcome measures. Music has been applied to healthy participants, as well as clinical populations to target anxiety and pain. But little is known about whether live music is more effective than recorded music as an intervention for these common symptoms.
This exploratory study sought answers with the emerging science of saliva analysis, which focuses on biomarkers that indicate stress and immune function. In this case salivary cortisol, alpha-amylase, immunoglobulin-A, interleukin- 1beta, and pH levels were measured. Saliva samples from 50 university students and 23 palliative care and surgical patients were compared before and after each participant listened to a live (ML), audiovisual (MAV) or audio recorded (MA) standardised program of classical music played on a solo violin, viola or cello. Live (SL) or audio (SA) story readings were added as interventions to control for psychosocial variables. Saliva’s non-invasive, repeatable, objective psychoneuroendocrine (PNE) snapshots were supplemented with subjective visual analogue scales for anxiety (VASA) and pain (VASP), and self-report affect scales to rate liking, perceived and felt emotion, and absorption. Participants were also asked for a one-word summary of their listening experience.
It was anticipated that ML would reduce anxiety and pain, as well as boost the immune markers, more than MAV and MA, and that music overall would demonstrate stronger benefits than the story readings.
No single outcome measure provided sufficient data to draw conclusions, but trends in the melange of both objective and subjective instruments revealed that overall more positive health indicators arose from live music than recorded music, particularly in the clinical settings. Stories were also shown to have some moderating effects on pain and anxiety. This study demonstrated the therapeutic values of music as well as story readings, and the superior benefits of live music and stories compared to audio recordings of the same presentations.
The PNE methodology had some limitations, particularly with the clinical population, resulting in gaps in the patients’ biomarker data. Some differential results highlighted the value of using a kaleidoscope of both objective and subjective outcome measures to gain a fuller understanding of the complex cognitive, emotional, neural, hormonal, and biopsychosocial processes involved in music’s beneficial effects.

If a set of predictors of treatment outcome could be found for a medical pain treatment, then screening of patients according to the predictors should increase treatment success. This may also help to channel patients who are unlikely to respond to such treatment towards other treatment options (Abram, Anderson and Maitra-D'Cruze 1981)...
