A Modern Approach to Regression with R

I have taught an undergraduate applied regression course for several years, and found few textbooks that are appropriate for modern students. To reveal my prejudices up front, what I want in an applied regression text are data, graphics, and computation. Data, because an applied regression course should give students an approach for understanding the world as it is revealed through data; the regression model is an end to a means but should not be treated as the end itself. Graphics, because not only are they important to modern regression, but they can help students develop a conceptual understanding of regression models. Computation, because data analysis via graphical and numerical regression is not possible without statistical software. The choice of software not only determines the sort of diagnostics and visualizations available to one’s students, but also influences how students understand regression itself.
Search log analysis method to uncover user search behaviour on web searching environment

User search behaviour was conceptualized as a strategy undertaken by the user in searching for information.Typically, searching activity on the web involved several steps; query formulation and reformulation, browsing the search results, and search results evaluation.The scope of this study has limited itself to query formulation that reflects the user search behaviour.The proposed method has been shown to successfully identify and classify user behaviour into two components namely; breadth search query and depth search query.The queries were initially recorded into search log through search interface.The search interface is one of the innovative tools that interface the Google search engine. Through this interface, user can enter the query and obtain the search results. In addition, the queries are also recorded for further analysis.
Rhetorical Structure Theory: Toward a functional theory of text organization

Rhetorical Structure Theory is a descriptive theory of a major aspect of the organization of natural text. It is a linguistically useful methodfor describing natural texts, characterizing their Structure primarily in terms of relations that hold between parts of the text. This paper establishes a new definitional foundation for RST. The paper also examines three Claims ofRST: the pre-dominance of nucleus/satellite structural pattems, the functional basis of hierarchy, and the communicative role oftext Structure
A family of routing and communication chips based on the Mosaic

This paper describes the speciications, internal design, and performance characteristics of the latest series of Caltech Mesh-Routing Chips (MRCs), slack-protocol-conversion chips, and router-interface chips. These high-performance, self-timed designs were derived from the corresponding parts of the message-passing system of the Mosaic (see the paper \The Design of the Caltech Mosaic C Multicomputer" in this volume), but are packaged as separate chips to allow their use by other projects engaged in the development of highly concurrent computers. In addition to n data bits, an MRC channel includes a bit to mark the tail of the packet, a self-timed request signal, and an opposite-going self-timed acknowledge signal. MRC channels operate in a queue (FIFO) discipline, in which the request and acknowledge signals provide both timing and ow control. The timing and electrical characteristics of these signals are critical to reliable communication between MRCs. The timing of the internal channels of an MRC is based on a transition-signaling, ripple-through FIFO whose properties are exploited to simplify the internal design the MRC. The MRC implements oblivious, dimension-order, blocking-cut-through (wormhole) routing with an internal organization based on elementary routing automata. Because the zero-slack protocol of an MRC channel limits the communication performance over long cables, Slack chips provide a conversion to a k-slack protocol. These Slack chips can be implemented with the same FIFO that is used in the MRCs. Dialog chips provide this same slack function, but within a protocol that allows a dialog of control symbols to be exchanged on a channel. In order to help the system designer deal with these high-speed, asyn-chronous channels, we also developed router-interface chips to provide synchronization and data conversion between MRC channels and microprocessor buses.
On the Adaptation to Non-Individualized HRTF Auralizations: A Longitudinal Study

Auralisations with HRTFs are an innovative tool for the reproduction of acoustic space. Their broad applicability depends on the use of non‐individualised models, but little is known on how humans adapt to these sounds. Previous findings have shown that simple exposure to non-individualised virtual sounds did not provide a quick adaptation, but that training and feedback would boost this process. Here, we were interested in analyzing the long-term effect of such training-based adaptation. We trained listeners in azimuth and elevation discrimination in two separate experiments and retested them immediately, one hour, one day, one week and one month after. Results revealed that, with active learning and feedback, all participants lowered their localization errors. This benefit was still found one month after training. Interestingly, participants who had trained previously with elevations were better in azimuth localization and vice-versa. Our findings suggest that humans adapt easily to new anatomically shaped spectral cues and they are able to transfer that adaptation to non‐trained sounds.
Exploring measures of vocabulary richness in semi-spontaneous French speech

This is the first major output of the French branch of the Language Learner Project, co-ordinated by Treffers-Daller. Whilst Tidball led the data collection and transcription of the French data and wrote the methodology chapter, Treffers-Daller formulated the research questions, provided the theoretical background, led the coding of the data in CHAT format, the computational analyses in CLAN and the statistical analyses in SPSS. Treffers-Daller also wrote most of the chapter (except the methodology section). The article is related to Daller's output 2, in that the issue of vocabulary richness is addressed in this chapter as well as in the journal article by Daller et al (2003). This article is the first one to make a detailed analysis of lexical richness in learner data, and it proposes a new measure of lexical richness which the authors developed in the course of the project. As there are very few indepth analyses of French vocabulary richness, this chapter makes an important contribution to our understanding of French learner language.
Demystifying data analysis: an alternative approach for managers of manufacturing SMEs

Purpose – Effective decision making is a crucial activity for manufacturing firms of all sizes. To this end, statistical techniques, such as variance theory, cognitive maps, heuristics and process theory, are widely used. However, such techniques rarely help chief executives to understand the dynamics of competitive behaviour, and often fail to bridge the gap between theory and practice. Indeed, from a small‐ and medium‐sized (SME) firm perspective, such techniques are rarely used owing to inadequate resources and/or skills. The paper seeks to address these issues.Design/methodology/approach – This paper proposes and tests a new approach to multivariate analysis based on the conditional formatting of spreadsheets. The analysis was confirmed using conventional statistical methods in order to validate the proposed methodology.Findings – The results are depicted as a visual picture of the attribute(s) under consideration and can be visually analysed.Originality/value – Such an approach can be used to complem.
Exploring the adoption of digital libraries in the mobile context

Following the narrow definition of the mobile Internet, ‘mobile libraries’ refers to digital libraries accessed by users through mobile phones and wireless networks. In order to explore users’ adoption of mobile libraries, a research model is developed focusing on two psychological factors (flow experience and innovativeness) and two factors oriented to the mobile context (ubiquitous connection and use context). Data collected from digital library users who are also users of the mobile Internet were used to test the model. The findings show that use context not only has a direct impact on users’ intention to adopt mobile libraries, but also partially mediates the effect of flow experience and ubiquitous connection on usage intention. Meanwhile, innovativeness both significantly affects usage intention and negatively moderates the effect of use context on usage intention. Findings and implications for theory and practice are discussed.
Le climat scolaire

« Le « climat scolaire » designe la qualite des relations qui se nouent entre les acteurs d'une meme experience scolaire, essentiellement entre eleves ou entre eleves et adultes d'une meme classe, d'un meme etablissement » Voici la description du climat scolaire proposee par Denis Meuret dans son ouvrage « Pour une ecole qui aime le monde » ((Meuret, Denis. Pour une ecole qui aime le monde Presse Universitaire 2013)). Cependant, il est difficile de donner une definition universelle et univoqu.
One-to-One Computing: What Does it Bring to Schools?

This study investigates students' use of one-to-one laptops for various activities and the impact of one-to-one computing on student learning and school culture. Based on data collected from surveys and interviews of teachers, students, and parents in a Midwestern middle school over one academic year, this study answers the following major questions: 1) How did students use their laptops? 2) What impact did the one-to-one laptop program have on student learning and school culture? 3) What were the perceptions of and concerns over one-to-one computing? A sound understanding of these issues is increasingly important as more and more schools are joining in this one-to-one computing initiative and more money is being invested. Results revealed that students used their laptops for various tasks related to learning, communication, expression, and exploration. Students gained significantly in their technology proficiency. The one-to-one laptops have provided great opportunities and resources for teaching and learning, but also raised issues such as student discipline problems, concerns on digital literacy, and fear of over-dependency on information technology.
REVISING THE INFLUENCE OF CONJUNCTIONS IN L2 READING COMPREHENSION

This article is based on a study investigating the impact of conjunctions on reading comprehension and summarization processes in Second Language under the light of the textbase model (Kintsch & van Dijk, 1978), and Theory of Cohesion (Halliday & Hasan, 1976). The lack of consensus regarding conjunctions in reading comprehension justifies this study. Data were collected from participants attending the fourth semester in Letras - Secretariado Executivo em Ingles (Universidade Federal de Santa Catarina). The study tasks comprised summarization, reading comprehension, gap-filling and a retrospective questionnaire. Overall results confirmed beneficial effects of conjunctions on reading comprehension.
The Role of Manipulatives in the Eighth Grade Mathematics Classroom

In this action research study of my classroom of eighth grade mathematics, I investigated the use of manipulatives and its impact on student attitude and understanding. I discovered that overall, students enjoy using manipulatives, not necessarily for the benefit of learning, but because it actively engages them in each lesson. I also found that students did perform better on exams when students were asked to solve problems using manipulatives in place of formal written representations of situations. In the course of this investigation, I also uncovered that student attitude toward mathematics improved when greater manipulative use was infused into the lessons. Students felt more confident that they understood the material, which translated into a better attitude regarding math class. As a result of this research, I plan to find ways to implement manipulatives in my teaching on a more regular basis. I intend to create lessons with manipulatives that will engage both hands and minds for the learners. Role of Manipulatives 1
Performance and efficacies in project-based action learning teams

This paper presents the empirical data obtained from a four-year case study on the implementation of a Project-Based Action Learning (PAL) framework. The study explores the correlation between performance and the various actors within the PAL setting. It extends the research on team learning and Organisational Learning (OL) beyond its boundaries through a four-year study in a real case company. The anticipated impacts of this research are twofold: to justify how a PAL approach is used as an OL driver and explore the various actors in the PAL setting who contribute to the PAL team's performance.
Cost benefit analysis: An informal introduction,

When this textbook was first published in 1971, the technique of cost-benefit analysis was scarcely recognized; nowadays it is an essential framework for any study of welfare economics, and continues to generate much controversy, concerned as it is with the fundamental principles on which our society operates. Over three editions the author has tested new ideas and principles against his original methodology, and revised and incorporated material to ensure that it remains one of the most thorough introductions to the subject yet available. Central to the appeal of the book is the lucid explanation of key concepts, and the simple, yet effective expository device of short chapters which encourages steady progress through the book.

Career Aspiration as Predictor of Students’ Performance in Cataloguing and Classification

This paper investigated career aspiration as predictor of students’ performance in cataloguing and classification with the major objectives of identifying the career aspiration of students studying cataloguing and classification and identifying the relationship between career aspiration and academic performance. The descriptive research design was used for the study. The population was made up of 129 students of Information Resources Management, Babcock University, Nigeria. Sampling was enumerative. Data was collected using a questionnaire. Results show that minority of the respondents desire to work as librarians or archivists. Even though respondents who aspire to work as librarians were more consistent in their perceived utility of cataloguing and classification, they were still out performed in academic performance by those aspiring for careers as bankers and system analysts. Based on the findings, the study concludes that library schools should find a way of accommodating varied career aspirations in a way that would enable students fit into their career choices while retaining the core librarianship courses. The study recommends that librarians and indeed library organisations make concerted efforts to market the library profession in order to attract prospective students who desire to pursue careers in librarianship amongst others. Keywords: Academic performance, Career aspiration, Cataloguing and classification, Librarianship, Subject utility
Automatic guidance of a vehicle based on DGPS and a 3D map

This paper presents an automatic guidance of an autonomous land vehicle based on DGPS and a 3D map. To compensate the positioning error of GPS, we used environmental sensing systems including video cameras, ultrasonic sensors and a 3D scanning laser rangefinder. The 3D map provides 3D environmental information and indicates landmarks for an image processing system to correct the positioning error of GPS. The image processing system also plays the role of obstacle detection. The 3D scanning laser rangefinder is used for speedy and accurate detection of obstacles. This paper describes the DGPS and a 3D map navigated driving system and presents the experimental results.
A Parallel Algorithm for Pricing American Options

We propose a novel, fast, accurate parallel algorithm for pricing American options. We perform a thorough numerical analysis of existing methodologies and find that ours performs significantly better. The proposed method is stable, robust, and converges monotonically. We also show that the efficiency can be improved further through the use of Richardson extrapolation. The method is well-suited for parallel implementations that take advantage of multi-core processors and graphic processing units.
Cancelamento do (r) final em nominais: uma abordagem difusionista

No presente trabalho, analisa-se o processo de cancelamento do (r) em itens nominais do portugues brasileiro a luz de duas propostas teoricas distintas – o Modelo Neogramatico, postulado por Labov (1972 e 1981), e o Modelo de Difusao Lexical, proposto por Wang (1969 e 1977). Defende-se, neste artigo, que o apagamento do (r) final em nominais se da gradativamente, atingindo os itens lexicos um a um, e que a frequencia de tipo e/ou de ocorrencia pode fazer com que uma palavra seja mais ou menos suscetivel a mudanca sonora.
The Effectiveness of Course Web Sites in Higher Education: An Exploratory Study

This article describes an exploratory study of the educational effectiveness of course Web sites among undergraduate students in accounting and graduate students in business statistics. We measured Web site visit frequency, the usefulness of each Web site feature, and the impacts of the Web sites on perceived learning and course performance. Graduate students visited the Web site significantly more often than did undergraduate students. In both groups, students rated course note availability and access to grades most useful and, relative to men, women felt that the Web site added more to their learning. Undergraduate students who visited the Web site more often and graduate students who found the discussion board more useful also perceived that the Web site contributed more to their learning. Finally, the graduate (but not the undergraduate) students who visited the Web site more often also performed better in the course.
Noniterative reconstruction of band limited signals and coding techniques

In this paper we propose linear iterative and noniterative algorithms which can efficiently correct a subset of t samples of a signal, whose values might have been corrupted, possibly due to noise, clipping, or any other reasons. We discuss the applicability of techniques used in error correcting codes to this problem, and the possibility of determining the location of the erroneous samples in oversampled band limited signals. The method borrows ideas from error-correcting codes such as BCH codes, but works in the complex field rather than in a Galois field. This work complements works in reconstruction theory which usually assume that the positions of lost samples or pixels are known, and improves on previously reported nonlinear iterative algorithms.
A general framework for tracking and analysing learning processes in computer‐supported collaborative learning environments

This paper describes a method for analysing the learning processes that take place in a computer‐supported collaborative learning (CSCL) environment. The approach is based on tracking the interactions between learners and tutors. Keeping track of meaningful events serves three main purposes: evaluation of the quality of the process, monitoring students’ performance in real time and the assessment of individual learning performances. The results can be of benefit to course designers, tutors/instructors and researchers involved in collaborative learning experiences. The method is based on a five‐dimensional model that includes a participative, an interactive, a social, a cognitive and a teaching dimension. Each dimension can be analysed through a set of indicators obtained by tracking course participants’ behaviour within the learning environment. Examples of significant indicators, drawn from the literature and the authors’ field experience, are discussed for each dimension. The paper also proposes a taxonomy of the data needed to obtain the described indicators. Finally, possible directions for further research are outlined.

Leidt het lezen van literaire fictie tot meer empathie? : een replicatiestudie van Kidd en Castano (2013)

Hoe kan het lezen van literatuur leiden tot een groter inlevingsvermogen in het dagelijks leven? Een technische term voor inlevingsvermogen is Theory of Mind (ToM). ToM is de vaardigheid om een mentale staat, intenties, kennis en verwachtingen toe te kennen aan jezelf en anderen, en je ook in mentale gesteldheden van anderen te verplaatsen. De originele achterliggende gedachte van het onderzoek van Kidd & Castano (2013) in Science was dat het lezen van literaire fictie in tegenstelling tot populaire fictie van invloed is op ToM. Deze gedachte kwam voort uit eerder onderzoek dat aantoonde dat het lezen van literatuur een empathie-verhogend effect zou hebben op lezers.
Language, Ideology and Point of View

This systematic introduction to the concept of point of view in language explores the ways in which point of view intersects with and is shaped by ideology. It specifically focuses on the way in which speakers and writers linguistically encode their beliefs, interests and biases in a wide range of media. The book draws on an extensive array of linguistic theories and frameworks and each chapter includes a self-contained introduction to a particular topic in linguistics, allowing easy reference. The author uses examples from a variety of literary and non-literary text types such as, narrative fiction, advertisements and newspaper reports.
