Seasonal dynamic pattern analysis in service of climate change research. A methodical case-study - monitoring and simulation based on an aquatic insect community

Our aim was to approach an important and well-investigable phenomenon – connected to a relatively simple but real field situation – in such a way, that the results of field observations could be directly comparable with the predictions of a simulation model-system which uses a simple mathematical apparatus and to simultaneously gain such a hypothesis-system, which creates the theoretical opportunity for a later experimental series of studies. As a phenomenon of the study, we chose the seasonal coenological changes of aquatic and semiaquatic Heteroptera community. Based on the observed data, we developed such an ecological model-system, which is suitable for generating realistic patterns highly resembling to the observed temporal patterns, and by the help of which predictions can be given to alternative situations of climatic circumstances not experienced before (e.g. climate changes), and furthermore; which can simulate experimental circumstances. The stable coenological state-plane, which was constructed based on the principle of indirect ordination is suitable for unified handling of data series of monitoring and simulation, and also fits for their comparison. On the state-plane, such deviations of empirical and model-generated data can be observed and analysed, which could otherwise remain hidden.

The effects of attribute quality information and sources of information on consumers' perceptions and behavior: A model of Pre-purchase Information Utilization in Service Physical Environments

The search-experience-credence framework from economics of information, the human-environment relations models from environmental psychology, and the consumer evaluation process from services marketing provide a conceptual basis for testing the model of "Pre-purchase Information Utilization in Service Physical Environments." The model addresses the effects of informational signs, as a dimension of the service physical environment, on consumers' perceptions (perceived veracity and perceived performance risk), emotions (pleasure) and behavior (willingness to buy). The informational signs provide attribute quality information (search and experience) through non-personal sources of information (simulated word-of-mouth and non-personal advocate sources).^ This dissertation examines: (1) the hypothesized relationships addressed in the model of "Pre-purchase Information Utilization in Service Physical Environments" among informational signs, perceived veracity, perceived performance risk, pleasure, and willingness to buy, and (2) the effects of attribute quality information and sources of information on consumers' perceived veracity and perceived performance risk.^ This research is the first in-depth study about the role and effects of information in service physical environments. Using a 2 x 2 between subjects experimental research procedure, undergraduate students were exposed to the informational signs in a simulated service physical environment. The service physical environments were simulated through color photographic slides.^ The results of the study suggest that: (1) the relationship between informational signs and willingness to buy is mediated by perceived veracity, perceived performance risk and pleasure, (2) experience attribute information shows higher perceived veracity and lower perceived performance risk when compared to search attribute information, and (3) information provided through simulated word-of-mouth shows higher perceived veracity and lower perceived performance risk when compared to information provided through non-personal advocate sources. ^

Enabling adaptability in service aggregates using transparent shaping techniques

Distributed applications are exposed as reusable components that are dynamically discovered and integrated to create new applications. These new applications, in the form of aggregate services, are vulnerable to failure due to the autonomous and distributed nature of their integrated components. This vulnerability creates the need for adaptability in aggregate services. The need for adaptation is accentuated for complex long-running applications as is found in scientific Grid computing, where distributed computing nodes may participate to solve computation and data-intensive problems. Such applications integrate services for coordinated problem solving in areas such as Bioinformatics. For such applications, when a constituent service fails, the application fails, even though there are other nodes that can substitute for the failed service. This concern is not addressed in the specification of high-level composition languages such as that of the Business Process Execution Language (BPEL). We propose an approach to transparently autonomizing existing BPEL processes in order to make them modifiable at runtime and more resilient to the failures in their execution environment. By transparent introduction of adaptive behavior, adaptation preserves the original business logic of the aggregate service and does not tangle the code for adaptive behavior with that of the aggregate service. The major contributions of this dissertation are: first, we assessed the effectiveness of BPEL language support in developing adaptive mechanisms. As a result, we identified the strengths and limitations of BPEL and came up with strategies to address those limitations. Second, we developed a technique to enhance existing BPEL processes transparently in order to support dynamic adaptation. We proposed a framework which uses transparent shaping and generative programming to make BPEL processes adaptive. Third, we developed a technique to dynamically discover and bind to substitute services. Our technique was evaluated and the result showed that dynamic utilization of components improves the flexibility of adaptive BPEL processes. Fourth, we developed an extensible policy-based technique to specify how to handle exceptional behavior. We developed a generic component that introduces adaptive behavior for multiple BPEL processes. Fifth, we identify ways to apply our work to facilitate adaptability in composite Grid services.

Perspectives of Teachers Regarding the Integration of Mathematics and Science at the Secondary School Level

The integration of mathematics and science in secondary schools in the 21st century continues to be an important topic of practice and research. The purpose of my research study, which builds on studies by Frykholm and Glasson (2005) and Berlin and White (2010), is to explore the potential constraints and benefits of integrating mathematics and science in Ontario secondary schools based on the perspectives of in-service and pre-service teachers with various math and/or science backgrounds. A qualitative and quantitative research design with an exploratory approach was used. The qualitative data was collected from a sample of 12 in-service teachers with various math and/or science backgrounds recruited from two school boards in Eastern Ontario. The quantitative and some qualitative data was collected from a sample of 81 pre-service teachers from the Queen’s University Bachelor of Education (B.Ed) program. Semi-structured interviews were conducted with the in-service teachers while a survey and a focus group was conducted with the pre-service teachers. Once the data was collected, the qualitative data were abductively analyzed. For the quantitative data, descriptive and inferential statistics (one-way ANOVAs and Pearson Chi Square analyses) were calculated to examine perspectives of teachers regardless of teaching background and to compare groups of teachers based on teaching background. The findings of this study suggest that in-service and pre-service teachers have a positive attitude towards the integration of math and science and view it as valuable to student learning and success. The pre-service teachers viewed the integration as easy and did not express concerns to this integration. On the other hand, the in-service teachers highlighted concerns and challenges such as resources, scheduling, and time constraints. My results illustrate when teachers perceive it is valuable to integrate math and science and which aspects of the classroom benefit best from the integration. Furthermore, the results highlight barriers and possible solutions to better the integration of math and science. In addition to the benefits and constraints of integration, my results illustrate why some teachers may opt out of integrating math and science and the different strategies teachers have incorporated to integrate math and science in their classroom.

English as a Lingua Franca in Namibia: : Teachers’ Attitudes Towards English as a Medium of Instruction in Classrooms

This study aims to investigate Namibian teachers’ attitudes towards English as a medium of instruction in Namibian classrooms. Regardless of the fact that English has no historical ties with Namibia, English still operates as the official language and the language of instruction in schools. This study briefly discusses the probable reasons for choosing English as an official language in Namibia, and as the medium of instruction in educational institutions. Furthermore, it discusses the attitudes that Namibian teachers have towards English as a medium of instruction in Namibian classrooms. A pilot electronic questionnaire, a revised questionnaire, and telephone interviews were used to acquire data for the study. The results indicate that English is a challenge for many learners and this poses a challenge to teachers as well. However, a majority of teachers from this study portray English as the language that is capable of uniting Namibian learners from different backgrounds, and a language that makes education possible in Namibia. In addition, teachers also reported that knowledge of English opens up educational opportunities for learners to study abroad.

In Service to Iowa : Public Library Standards, 6th edition, August 8, 2016

The Standards and Accreditation Program exists to encourage the ongoing development of high quality public library services in Iowa. In Service to Iowa: Public Library Standards is the manual for the State Library of Iowa’s standards program. It was first published in 1985 and was updated in 1989, 1997, 2004, 2010, and now in 2016. Iowa’s voluntary public library standards program was established to give public libraries a tool to identify strengths and areas for improvement. It is also used to document the condition of public library service in Iowa, to distribute Direct State Aid funding, and to meet statutory requirements. In 2015, the Iowa Commission of Libraries appointed the Public Library Standards Advisory Task Force to revise In Service to Iowa. The Task Force in turn solicited feedback from the State Library Advisory Panel to ensure that proposed standards meet the changing needs of Iowa’s public libraries. All task force members support and stress the importance of the accreditation process and thank the Iowa public library community for its assistance.

Effects of an in-service training program using the routines-based interview

The focus of this study is an in-service training program rooted in routines-based early intervention and designed to improve the quality of goals and objectives on individualized plans. Participants were local intervention team members and other professionals who worked closely with each team. This training program involved a small number of trainees per group, providing multiple learning experiences across time and various opportunities for self-assessment and monitoring. We investigated (a) the perceptions of the participants about the strengths and weaknesses of the training program, (b) medium-term outcomes of the training with a comparison group, (c) and variables associated with the quality of goals and objectives. This study involved training more than 200 professionals, and results support the effectiveness of the program in improving the quality of goals and objectives, showing the importance of the routines-based interview in producing that improvement.

UNDERSTANDING CUSTOMER CHOICES IN SERVICE OUTSOURCING AND REVENUE MANAGEMENT

This dissertation investigates customer behavior modeling in service outsourcing and revenue management in the service sector (i.e., airline and hotel industries). In particular, it focuses on a common theme of improving firms’ strategic decisions through the understanding of customer preferences. Decisions concerning degrees of outsourcing, such as firms’ capacity choices, are important to performance outcomes. These choices are especially important in high-customer-contact services (e.g., airline industry) because of the characteristics of services: simultaneity of consumption and production, and intangibility and perishability of the offering. Essay 1 estimates how outsourcing affects customer choices and market share in the airline industry, and consequently the revenue implications from outsourcing. However, outsourcing decisions are typically endogenous. A firm may choose whether to outsource or not based on what a firm expects to be the best outcome. Essay 2 contributes to the literature by proposing a structural model which could capture a firm’s profit-maximizing decision-making behavior in a market. This makes possible the prediction of consequences (i.e., performance outcomes) of future strategic moves. Another emerging area in service operations management is revenue management. Choice-based revenue systems incorporate discrete choice models into traditional revenue management algorithms. To successfully implement a choice-based revenue system, it is necessary to estimate customer preferences as a valid input to optimization algorithms. The third essay investigates how to estimate customer preferences when part of the market is consistently unobserved. This issue is especially prominent in choice-based revenue management systems. Normally a firm only has its own observed purchases, while those customers who purchase from competitors or do not make purchases are unobserved. Most current estimation procedures depend on unrealistic assumptions about customer arriving. This study proposes a new estimation methodology, which does not require any prior knowledge about the customer arrival process and allows for arbitrary demand distributions. Compared with previous methods, this model performs superior when the true demand is highly variable.

Constructing and reconstructing teaching roles: A focus on generative metaphors and dichotomies

Over the last several decades, a shift in thinking has brought to the fore the power of language as more than simply a method of expression. Indeed, language is a constituent part of social practices and social identity. For teachers, both pre-service and in-service, teaching roles are often represented through surface and generative metaphors, the latter of which are tacit. In order to study the way in which language, and in particular metaphor, influences thinking about teaching roles, the authors of this article combined their data to examine the metaphoric discourse of both pre-service and in-service teachers. Contextualizing two separate studies in their respective teacher education programs, this article highlights the obstacle of unexposed generative metaphors and the value of ongoing professional development. In addition, it emphasizes the importance of deconstructing traditional dichotomies as central to teacher education reform.

Integrated didactics: an example of a curriculum model enhancing knowledge crossing

In this paper, we introduce an innovative course in the Portuguese Context, the Master's Course in “Integrated Didactics in Mother Tongue, Maths, Natural and Social Sciences”, taking place at the Lisbon School of Education and discussing in particular the results of the evaluation made by the students who attended the Curricular Unit - Integrated Didactics (CU-ID). This course was designed for in-service teachers of the first six years of schooling and intends to improve connections between different curriculum areas. In this paper, we start to present a few general ideas about curriculum development; to discuss the concept of integration; to present the principles and objectives of the course created as well as its structure; to describe the methodology used in the evaluation process of the above mentioned CU-ID. The results allow us to state that the students recognized, as positive features of the CU-ID, the presence in all sessions of two teachers simultaneously from different scientific areas, as well as invitations issued to specialists on the subject of integration and to other teachers that already promote forms of integration in schools. As negative features, students noted a lack of integrated purpose, applying simultaneously the four scientific areas of the course, and also indicated the need to be familiar with more models of integrated education. Consequently, the suggestions for improvement derived from these negative features. The students also considered that their evaluation process was correct, due to the fact that it was focused on the design of an integrated project for one of the school years already mentioned.

Avaliação de necessidades de formação em professores do ensino secundário em Cabo Verde

II Resumo Cabo Verde é um país que tem acompanhado as grandes mudanças políticas, sociais, económicas e educativas, atribuindo um papel preponderante aos professores na educação/formação dos indivíduos. Neste sentido a formação inicial não pode constituir um acto “acabado” que não tem em linha de conta as mudanças que decorrem no seu seio. A formação contínua aparece com um processo de construção da mudança, apoiado no desenvolvimento profissional dos professores. A avaliação de necessidade de formação em professores do ensino secundário em Cabo Verde é o tema do trabalho de investigação, realizado nas escolas secundárias da ilha de Santo Antão, em Cabo Verde, no sentido de identificar questões problemáticas na formação inicial e contínua de professores e as suas implicações na qualidade educativa. Neste sentido, ao longo de 5 capítulos apresentamos os pontos desta investigação, estruturados de forma a se poder acompanhar a sua evolução. No 1º capítulo, apresenta-se a Problemática de Investigação, que constitui a parte inicial da dissertação, pela exposição do quadro conceptual do ensino secundário em Cabo Verde através da contextualização e identificação do problema, da formulação dos objectivos e questões de investigação. No 2º capítulo faz-se o percurso histórico/educativo de Cabo Verde, desde a época colonial, passando pela educação após a independência em 1975, à constituição da Lei de Bases do Sistema Educativo e a Reforma Educativa dos anos 90. No 3º capítulo, intitulado “A Formação Inicial e Continua de Professores em Cabo Verde”, é abordado o enquadramento teórico desta investigação, com referência à contextualização geral da formação e modelos de formação de professores, evoluindo para a realidade Cabo-verdiana, tendo em consideração as instituições de formação de professores e o contexto actual do ensino secundário em Cabo Verde. No 4º capítulo faz-se a apresentação da Metodologia de Investigação, adoptada num estudo extensivo, do qual abordamos a natureza da investigação e caracterizamos a amostra e respondentes. Como técnicas de recolha de dados, são utilizados: o inquérito por questionário (n=77), a professores do ensino secundário e o inquérito por entrevista (n=9), aos directores das escolas secundárias da ilha de Santo Antão e a formadores de professores em São Vicente. Como técnica de análise de dados, são utilizados diversos procedimentos estatísticos e a análise de conteúdo. O 5º capítulo corresponde a apresentação e discussão dos resultados da investigação desses três públicos analisados. Para finalizar, apresenta-se uma conclusão que corresponde a síntese dos resultados obtidos, propostas de sugestões de melhoria e limitações do estudo. Cabo Verde is a country willing to follow the great political, social, economic and educational changes. This important role have attributed to teachers to educate and train individuals. In this sense the initial training cannot be considered as a “finished” task without taking into consideration those changes. The in service training appears as a scientific and pedagogic autonomization towards the growing change. The Evaluation of Secondary School teacher training Needs in Cabo Verde constitutes an investigation work, carried out in Santo Antão's island Secondary schools, aiming to identify problems in initial and continuous teachers' training and their implications in the educational quality. In this sense, along five chapters we will present the points of this investigation, structured to facilitate the understanding of its evolution. In the first chapter we present the Problem of Investigation which is an introductory part of the dissertation, the conceptual theory of the Cabo Verde secondary education through the contextualization and identification of the problem, the formulation of the objectives and investigation issues. In the second chapter we present the Cabo Verde historical/educational background, from the colonial time, going through after independence in 1975, to the constitution of the Basic Educational Law of the System and the nineties Educational Reform. In the third chapter entitled “The Initial and in-service Teacher´s Training in Cabo Verde” brings the theoretical framework of this investigation, where we present a general contextualization of teachers' training and models, developed from the reality of Cabo Verde. In this regard we will consider the teachers' training institutions and the current secondary education context in Cabo Verde. In the fourth chapter we present the Research Methodology, adopted in an extensive study, of which we draw the nature of the investigation and we characterized the sample. We carried out questionnaire (n=77) to teachers, interviews (n=9) to headmasters from Santo Antão's island secondary schools and trainers from São Vicente. We used statistical analyses and content analyses as data analyse techniques. The fifth chapter deals with presentation the discussion of results of those three analyzed publics' investigation. Finally, we present a summary of the obtained results, suggestions for improvement and limitations of study.
