El presente trabajo tiene como objetivo evaluar el aprendizaje de los deportes colectivos en el alumnado de segundo ciclo de Educación Secundaria Obligatoria (ESO) utilizando una herramienta denominada Game Performance Assessment Instrument (GPAI). Para ello se ha realizado una revisión de dos modelos de enseñanza existentes: el modelo técnico y el modelo comprensivo. Así mismo hemos revisado dos tipos de procesos de evaluación; por un lado la evaluación sumativa, más relacionada con el modelo técnico; por otro lado la evaluación formativa, más próxima al modelo comprensivo. A continuación se ha llevado a cabo una intervención didáctica aplicando el modelo de enseñanza comprensivo (TGfU) y el instrumento mencionado anteriormente (GPAI). Los resultados obtenidos han sido utilizados para proponer un sistema de evaluación basado en el modelo comprensivo con la utilización del GPAI y a través de la coevaluación como forma de asentar el aprendizaje en el alumnado. Se concluye que el modelo de enseñanza comprensivo (TGfU) con el GPAI y una evaluación entre iguales es bastante óptimo para favorecer el proceso de enseñanzaaprendizaje de los deportes colectivos en el alumnado de segundo ciclo de Educación Secundaria Obligatoria (ESO). ABSTRACT The present work has the aim to assess the learning of collective sports in Secondary Education students using a tool called Game Performance Assessment Instrument (GPAI). For that we have used to revision of two teaching models: the technical model and Teaching Games for Understanding (TGfU). At the same time, we have reviewed two kinds of assessment process; on one hand summative assessment which is related to technical model; on the other hand formative assessment nearest to Teaching Games for Understanding (TGfU). Next it has been done a didactic intervention using the Teaching Games for Understanding (TGfU) and that instrument mentioned beforehand. The results obtained have been used to suggest an assessment system based on Teaching Games for Understanding (TGfU) using the GPAI through the peer assessment as a way of teaching.

The Rorschach Performance Assessment System (R-PAS) was developed in 2011 as analternative to the previous Comprehensive System. The goal was to improve the psychometrics,and particularly the validity, of this assessment method. The norms for children werequestionable in the Comprehensive system (e.g., outdated, low numbers of subjects) and validitystudies for children were sparse. One of the indicators included in the R-PAS system, theaggressive content indicator (AgC), is intended to reflect aggressive behavior, but few studieshave examined the validity of this indicator. This study examined the validity of AgC in asample of 32 children and adolescents receiving services at a residential treatment center.Subjects' AgC scores were analyzed in relation to demographics and diagnosis, as well as ratingsof aggression and conduct problems from the Behavioral Assessment System for Children-2(BASC-2) Parent and Teacher Reports. Correlations between the AgC score and BASC-2aggression and conduct problems scores were not statistically significant. None of thecorrelations between AgC score and a diagnosis of Conduct Disorder, Oppositional DefiantDisorder, Posttraumatic Stress Disorder, or Mood Disorders were significant either. Given thesmall sample size, null results may be a result of power concerns. The lack of significantcorrelations may however, indicate that operational definitions of aggression used in variousforms of measurement reflect different constructs.

O presente estudo procura estabelecer a relação entre a Percepção de Justiça e Satisfação com o Sistema de Avaliação de Desempenho. A metodologia utilizada foi a quantitativa, pois permite validar a revisão da literatura efetuada, onde se procura analisar a relação entre a Percepção de Justiça e a Satisfação com o Sistema de Avaliação de Desempenho através de um conjunto de hipóteses que posteriormente serão testadas. Para se testar as hipóteses recolheu-se os dados através da adaptação de um questionário já aplicado em Portugal (Porfírio, 2006). O mesmo foi aplicado a 89 funcionários de uma empresa do ramo Transitário. Para o tratamento dos dados recolhidos vai ser utilizado o programa IBM SPSS Statistics 20. De acordo com os resultados obtidos verificou-se que existe uma relação positiva e significativa entre a Percepção de Justiça na dimensão Distributiva e a Satisfação com o Sistema de Avaliação de Desempenho. Não se tendo verificado o mesmo para a dimensão Procedimental. Em relação ao Big Five podemos constatar que é significativo e que exerce controlo entre a Percepção de Justiça Distributiva e a Satisfação com o Sistema de Avaliação de Desempenho, não se tendo comprovado o mesmo para a Percepção de Justiça Procedimental.

This thesis presents a number of methodological developments that were raised by a real life application to measuring the efficiency of bank branches. The advent of internet banking and phone banking is changing the role of bank branches from a predominantly transaction-based one to a sales-oriented role. This fact requires the development of new forms of assessing and comparing branches of a bank. In addition, performance assessment models must also take into account the fact that bank branches are service and for-profit organisations to which providing adequate service quality as well as being profitable are crucial objectives. This study analyses bank branches performance in their new roles in three different areas: their effectiveness in fostering the use of new transaction channels such as the internet and the telephone (transactional efficiency); their effectiveness in increasing sales and their customer base (operational efficiency); and their effectiveness in generating profits without compromising the quality of service (profit efficiency). The chosen methodology for the overall analysis is Data Envelopment Analysis (DEA). The application attempted here required some adaptations to existing DEA models and indeed some new models so that some specialities of our data could be handled. These concern the development of models that can account for negative data, the development of models to measure profit efficiency, and the development of models that yield production units with targets that are nearer to their observed levels than targets yielded by traditional DEA models. The application of the developed models to a sample of Portuguese bank branches allowed their classification according to the three performance dimensions (transactional, operational and profit efficiency). It also provided useful insights to bank managers regarding how bank branches compare between themselves in terms of their performance, and how, in general, the three performance dimensions are connected between themselves.

Az ellátási lánc menedzsmentje jól ismert és régóta tanulmányozott területe a menedzsment tudománynak. Jelen tanulmány célja, hogy egy olyan modell létezését igazolja, amely szerint egy ellátási láncban az információ menedzsmentje, az anyagi áramlások koordinációja és költségek és a teljesítmény kontrollja elengedhetetlen a teljes lánc magas szintű teljesítményéhez, és ezt a kockázatmenedzsment eszközök alkalmazásával tovább lehet növelni. Az ellátási lánc menedzsment eszközök támogatják a partnerek közötti információ megosztást (pl. EDI), az anyagi áramlások kisimítását (pl. folyamatos feltöltés, cross-docking). A költség és teljesítmény menedzsment eszközök alkalmazásának célja pedig hogy feltárják, hogy a költségek és hasznok miként oszlanak meg, merülnek fel az egyes ellátási lánc szereplők között. Ezeket az eszközöket akár vállalati, akár ellátási lánc szinten alkalmazzák, a végső cél a teljes ellátási lánc teljesítményének a növelése. Az ellátási lánc teljesítményét úgy határozzuk meg, mint az érték, amely a végső vevő számára keletkezett valamint a profit, amit az ellátási lánc partnerek realizáltak. Habár a vállalatok és az ellátási láncok különféle eszközöket alkalmazhatnak, hogy menedzseljék különböző folyamataikat, az a mód, ahogy szembenéznek a felmerülő kockázatokkal – fakadjanak akár a rendszerből magából, vagy a környezetből - és kezelik azokat, alapvető hatással bír a végső teljesítményre, így a versenyképességre is. A bemutatott kutatási modellel azt a kapcsolatot szeretnénk igazolni, amely feltevéseink szerint az ellátási láncban alkalmazott, a különféle alapfolyamatok menedzsmentjére valamint a kockázat menedzsmentjére használt eszközök és a realizált teljesítmény között van. _______ Supply chain management is a well-known and intensely studied field of management science. Our aim is to construct and test a model which summarises that besides the tools adapted to manage information flow, materials flow and costs and performance in supply chains to achieve high overall performance, managing risks is also inevitable. Supply chain management tools are to improve the efficiency of information sharing between supply chain participants (e.g. EDI) and to smooth materials flow carried out by the parties in collaboration (e.g. continuous replenishment, cross-docking). Cost management and performance assessment tools aim to explore the costs and profit realised by the cooperating companies as well as the entire supply chain. All the tools adapted either at a company or on supply chain level, strive to enhance the overall performance of the supply chain. The performance of a supply chain can be assessed by the value created for the end consumer and by the profit the partners realise. However, companies and supply chains adopt tools to manage the different flows, the way they face and handle risks coming either from the system or from the surrounding environment have a key influence on the performance achieved and consequently on competitiveness, too. When constructing the research model we try to find and verify the linkage between the tools supply chains use for coordination and for managing risks and the performance achieved.

The idea of comparative performance assessment is crucial. Recent study findings show that in South Florida the use by most municipalities of external benchmarks for performance comparison is virtually non-existent. On one level this study sought to identify the factors impacting resident perceptions of municipal service quality. On a different and more practical level, this study sought to identify a core set of measures that could serve for multi jurisdictional comparisons of performance. ^ This study empirically tested three groups of hypotheses. Data were collected via custom designed survey instruments from multiple jurisdictions, representing diverse socioeconomic backgrounds, and across two counties. A second layer of analysis was conducted on municipal budget documents for the presence of performance measures. A third layer of analysis was conducted via face-to-face interviews with residents at the point of service delivery. Research questions were analyzed using descriptive and inferential statistic methodologies. ^ Results of survey data yielded inconsistent findings. In absolute aggregated terms, the use of sociological determinants to guide inquiry failed to yield conclusive answers regarding the factors impacting resident perceptions of municipal service quality. At disaggregated community levels, however, definite differences emerged but these had weak predictive ability. More useful were the findings of performance measures reporting via municipal budget documents and analyses of interviews with residents at the point of service delivery. Regardless of socio-economic profile, neighborhood characteristics, level of civic engagement or type of community, the same aspects were important to citizens when making assessments of service quality. For parks and recreation, respondents most frequently cited maintenance, facility amenities, and program offerings as important while for garbage collection services timely and consistent service delivery mattered most. Surprisingly municipalities participating in the study track performance data on items indicated as important by citizen assessments but regular feed back from residents or reporting to the same is rarely done. ^ The implications of these findings suggest that endeavors, such as the one undertaken in this study, can assist in determining a core set of measures for cross jurisdictional comparisons of municipal service quality, improving municipal delivery of services, and to communicate with the public. ^

Higher education institutions across the United States have developed global learning initiatives to support student achievement of global awareness and global perspective, but assessment options for these outcomes are extremely limited. A review of research for a global learning initiative at a large, Hispanic-serving, urban, public, research university in South Florida found a lack of instruments designed to measure global awareness and global perspective in the context of an authentic performance assessment. This quasi-experimental study explored the development of two rubrics for the global learning initiative and the extent to which evidence supported the rubrics' validity and reliability. One holistic rubric was developed to measure students' global awareness and the second to measure their global perspective. The study utilized a pretest/posttest nonequivalent group design. Multiple linear regression was used to ascertain the rubrics' ability to discern and compare average learning gains of undergraduate students enrolled in two global learning courses and students enrolled in two non-global learning courses. Parallel pretest/posttest forms of the performance task required students to respond to two open-ended questions, aligned with the learning outcomes, concerning a complex case narrative. Trained faculty raters read responses and used the rubrics to measure students' global awareness and perspective. Reliability was tested by calculating the rates of agreement among raters. Evidence supported the finding that the global awareness and global perspective rubrics yielded scores that were highly reliable measures of students' development of these learning outcomes. Chi-square tests of frequency found significant rates of inter-rater agreement exceeding the study's .80 minimum requirement. Evidence also supported the finding that the rubrics yielded scores that were valid measures of students' global awareness and global perspective. Regression analyses found little evidence of main effects; however, post hoc analyses revealed a significant interaction between global awareness pretest scores and the treatment, the global learning course. Significant interaction was also found between global perspective pretest scores and the treatment. These crossover interactions supported the finding that the global awareness and global perspective rubrics could be used to detect learning differences between the treatment and control groups as well as differences within the treatment group.

This study is about the enhancement of the elementary school in Natal/RN, (PCCR - Law No. 058/2004), concerning to the horizontal promotion through the performance evaluation. It uses as reference the education policy on the legislative field hegemony and the managerial model. The analysis of the teacher´s valorization is based on the policy of Funds (Fundef and Fundeb) in the Brazilian social and educational agenda. The study focuses on the Career Plan, Career and Remuneration of teachers in the period (2004-2010).The study focuses on the Career Plan, Career and Remuneration of teachers in the period (2004-2010). The thesis argues for the necessity to adopt a direct relationship between career development and horizontal promotion for more others fifteen classes, no matter to any conditioning variables. In addition, the performance shall be evaluated by interval of 25 years to reach at least the provisions decided in the law, which determines the salary adjustment in 5% at every two years, as pointed at the PCCR, about teachers remuneration, and teachers qualifications. A work of a bibliographic and a documental review about the education funding with the purpose of enhancement of educational work, career concepts, and also promotion and evaluation performance as well was performed based on experts authors in this field. The survey was organized with the aim of articulating quantitative and qualitative information, analyzing data from the teacher's salary - payrolls and paychecks - also applying a questionnaire. After the implementation of the PCCR, it was found that the wage indices for horizontal promotion during the teaching career are tied to a strategy for evaluating the performance which disqualifies the teacher‟s salaries in a minimum percentage of 25% (up to 25 years) and there are also elements that disturb the promotion strategy. The national minimum wage was set in three salaries by the PSPN Lei nº11.738/2008 but it never reaches the three salaries at Natal/RN educational system.Otherwise, the elements that structure the horizontal promotion in fifteen classes, throughout the career, flout the minimum years of teaching work, long established in 25 years. In addition, changes in terms in the salary increase depend on individual efforts by professional development through titration. Concerning to the career, despite of the category approving its PCCR, neither this instrument nor the Funds Policy managed to establish regulations were able to cope effective rules for valuing the teachers in the educational district system. It is necessary to ensure, in percentage terms and financial, the real remuneration of teachers with the attainment of horizontal promotion, reviewing the elements that structure the career and the determinants of performance evaluation.

The uncontrolled disposal of wastewaters containing phenolic compounds by the industry has caused irreversible damage to the environment. Because of this, it is now mandatory to develop new methods to treat these effluents before they are disposed of. One of the most promising and low cost approaches is the degradation of phenolic compounds via photocatalysis. This work, in particular, has as the main goal, the customization of a bench scale photoreactor and the preparation of catalysts via utilization of char originated from the fast pyrolysis of sewage sludge. The experiments were carried out at constant temperature (50°C) under oxygen (410, 515, 650 and 750 ml min-1). The reaction took place in the liquid phase (3.4 liters), where the catalyst concentration was 1g L-1 and the initial concentration of phenol was 500 mg L-1 and the reaction time was set to 3 hours. A 400 W lamp was adapted to the reactor. The flow of oxygen was optimized to 650 ml min-1. The pH of the liquid and the nature of the catalyst (acidified and calcined palygorskite, palygorskite impregnated with 3.8% Fe and the pyrolysis char) were investigated. The catalytic materials were characterized by XRD, XRF, and BET. In the process of photocatalytic degradation of phenol, the results showed that the pH has a significant influence on the phenol conversion, with best results for pH equal to 5.5. The phenol conversion ranged from 51.78% for the char sewage sludge to 58.02% (for palygorskite acidified calcined). Liquid samples analyzed by liquid chromatography and the following compounds were identified: hydroquinone, catechol and maleic acid. A mechanism of the reaction was proposed, whereas the phenol is transformed into the homogeneous phase and the others react on the catalyst surface. For the latter, the Langmuir-Hinshelwood model was applied, whose mass balances led to a system of differential equations and these were solved using numerical methods in order to get estimates for the kinetic and adsorption parameters. The model was adjusted satisfactorily to the experimental results. From the proposed mechanism and the operating conditions used in this study, the most favored step, regardless of the catalyst, was the acid group (originated from quinone compounds), being transformed into CO2 and water, whose rate constant k4 presented value of 0.578 mol L-1 min-1 for acidified calcined palygorskite, 0.472 mol L-1 min-1 for Fe2O3/palygorskite and 1.276 mol L-1 min-1 for the sludge to char, the latter being the best catalyst for mineralization of acid to CO2 and water. The quinones were adsorbed to the acidic sites of the calcined palygorskite and Fe2O3/palygorskite whose adsorption constants were similar (~ 4.45 L mol-1) and higher than that of the sewage sludge char (3.77 L mol-1).

Complexity science is the multidisciplinary study of complex systems. Its marked network orientation lends itself well to transport contexts. Key features of complexity science are introduced and defined, with a specific focus on the application to air traffic management. An overview of complex network theory is presented, with examples of its corresponding metrics and multiple scales. Complexity science is starting to make important contributions to performance assessment and system design: selected, applied air traffic management case studies are explored. The important contexts of uncertainty, resilience and emergent behaviour are discussed, with future research priorities summarised.

Air traffic management research lacks a framework for modelling the cost of resilience during disturbance. There is no universally accepted metric for cost resilience. The design of such a framework is presented and the modelling to date is reported. The framework allows performance assessment as a function of differential stakeholder uptake of strategic mechanisms designed to mitigate disturbance. Advanced metrics, cost- and non-cost-based, disaggregated by stakeholder sub-types, are described. A new cost resilience metric is proposed and exemplified with early test data.

Students reflect more on their learning in course subjects when they participate in managing their teaching–learning environment. As a form of guided participation, peer assessment serves the following purposes: (a) it improves the student’s understanding of previously established learning objectives; (b) it is a powerful metacognitive tool; (c) it transfers to the student part of the responsibility for assessing learning, which means deciding which learning activities are important and choosing the degree of effort a course subject will require; (d) it emphasizes the collective aspect of the nature of knowledge; and (e) the educational benefits derived from peer assessment clearly justify the efforts required to implement activities. This paper reports on the relative merits of a learning portfolio compiled during fine arts-related studies in which peer assessment played an important role. The researchers analyzed the student work load and the final marks students received for compulsory art subjects. They conclude that the use of a closed learning portfolio with a well-structured, sequential and analytical design can have a positive effect on student learning and that, although implementing peer assessment may be complex and students need to become familiar with it, its use is not only feasible but recommendable.

Nowadays, evaluation methods to measure thermal performance of buildings have been developed in order to improve thermal comfort in buildings and reduce the use of energy with active cooling and heating systems. However, in developed countries, the criteria used in rating systems to asses the thermal and energy performance of buildings have demonstrated some limitations when applied to naturally ventilated building in tropical climates. The present research has as its main objective to propose a method to evaluate the thermal performance of low-rise residential buildings in warm humid climates, through computational simulation. The method was developed in order to conceive a suitable rating system for the athermal performance assessment of such buildings using as criteria the indoor air temperature and a thermal comfort adaptive model. The research made use of the software VisualDOE 4.1 in two simulations runs of a base case modeled for two basic types of occupancies: living room and bedroom. In the first simulation run, sensitive analyses were made to identify the variables with the higher impact over the cases´ thermal performance. Besides that, the results also allowed the formulation of design recommendations to warm humid climates toward an improvement on the thermal performance of residential building in similar situations. The results of the second simulation run was used to identify the named Thermal Performance Spectrum (TPS) of both occupancies types, which reflect the variations on the thermal performance considering the local climate, building typology, chosen construction material and studied occupancies. This analysis generates an index named IDTR Thermal Performance Resultant Index, which was configured as a thermal performance rating system. It correlates the thermal performance with the number of hours that the indoor air temperature was on each of the six thermal comfort bands pre-defined that received weights to measure the discomfort intensity. The use of this rating system showed to be appropriated when used in one of the simulated cases, presenting advantages in relation to other evaluation methods and becoming a tool for the understanding of building thermal behavior
