Clinging to Traditional Reference Services: An Open Invitation to Libref.com.

ities (as a part of our overall public services) and determine at what level to fund them for the next year. Making this assessment is typically difficult, since the circum stances of reference are increasing ly complex and ambiguous. The complexity derives both from the continuing digitization of pub lished knowledge and the advent of distance learning (which has begun to separate the reference librarian and the user). I admit that making an assessment is also diffi cult because I intuitively believe that reference service is important but find it increasingly out of touch? so the assessment process is a struggle between my heart and my head. What I will share with you here is my current view, as an administrator, of reference services in an academic library setting. A Current Assessment of Reference
Collaborative notebooks for the virtual workplace

This chapter discusses issues in the design of information sharing software systems for the virtual workplace. The discussion focusses on the trial use of a purpose-built shared collaborative notebook by a group of software engineers, managers and support staff distributed over two widely separated sites. The design of the notebook and the user context are described, and the results of the pilot trial reported. These results showed a partial take-up of the technology and clear variation between technical and nontechnical staff in levels of use. The findings indicate that when designing information sharing systems of this type (i) the true extent of the collaboration in question must be elucidated; (ii ) the system should allow for the fact that willingness to share information is at least partially determined by its the perceived formality or informality and the perceived formality or informality of the medium for sharing; (iii) the application must bridge the gap between personal and business information systems.
Modelling and Diagnostics of Low Pressure Plasma Discharges

The presented thesis deals with various aspects of models for low pressure discharges. As well the theoretical background of hydrodynamic plasma models as the comparison of calculated data with experimental results are discussed. In the first part of this work hydrodynamic conservation equations are derived from the Boltzmann equation. Main focus is the application to low pressure plasmas. Different model systems for electrons and ions are presented. The question in which case simplified models can be applied, is treated as well as numerical aspects and algorithms for obtaining a solution are discussed. In a second part hydrodynamic models were used for performing one-dimensional simulations. The sensitivity of the model in dependence of input parameters like momentum exchange frequencies was analysed. As well different model systems were compared qualitatively in order to get an estimate for the error introduced by using simple and numerical more stable model systems. In the third part hydrodynamic models were applied to simulate different kinds of low pressure discharges. Main focus were inductively driven plasmas like they are used in semiconductor fabrication as high density plasma source. Calculated data for this kind of discharge were compared with experimental values obtained from Langmuir probe measurements. Theory and experiment show very good agreement. In a final part the scaling laws and geometry dependence derived from hydrodynamic models were used to assemble a set of general reactor design rules. Examples were presented, how reactor performance can be optimised by careful choice of geometry parameters. Also general dependencies on external parameters like discharge pressure were discussed.
INDIRECT FEEDBACK OF HAPTIC INFORMATION FOR ROBOT-ASSISTED TELEMANIPULATION

A port control member (24) of a metering valve (10) is mechanically connected to a pilot operated foot pedal (38). Foot pedal (38) movement of this member (24) meters fluid pressure to a second electrically controlled metering valve (108, 110, 112). Pressure from the second metering valve (108, 110, 112) is delivered to one end of a port control member (126) of a third metering valve (126, 136, 138, 140). The third metering valve (126, 136, 138, 140) meters pressure and flow from a supply pressure to wheel brakes (50). Feedback pressure from the brakes (142) is applied to the port control member (126) in opposition to the command pressure (124). The command pressure (108, 110, 112) is fed back to act on the port control member (24) of the first stage valve (10) in opposite relation to the pilot developed pedal force.
Bi-directional Development of L2 Suprasegmentals

This study investigated bi-directional development of L2 suprasegmentals when second language learners acquire L2. L2 speech of native Korean and English speakers with various length of immersion was compared and analyzed. It was expected that the longer immersed L2 learners would have suprasegmental features more similar to native L1 speakers compared with the shorter immersed learners, while the variation in L2 acquisition could be extended by the effect of background language. Both experiments for Korean learners of English and English learners of Korean were carried out to check the hypothesis. The results showed that L2 longer-immersed groups exerted the similar features of L1 native speakers. The direction of L2 development, however, was different. As a result, both groups have features with similar and different patterns at the same time. The similar features are realized in temporal features, while the contrastive features are found in the spectral cues. The result suggests that L2 development is determined by both factors: L1 background language and universal L2 developmental patterns.
Comportamiento al intemperismo natural de compositos polipropileno-madera

Se estudio el comportamiento al intemperismo de compositos polipropileno-madera formulados con particulas de pino malla 60,100 y finos, con proporciones de polipropileno-madera 67-30, 57-40 y 47-50, con 2 % de agente acoplante (Maleic Anhydride Polypropylene) y 1 % de estearato de calcio. Estos fueron sometidos a 2 856 h (septiembre-enero) de intemperismo natural.Se evaluaron los efectos de la radiacion solar y humedad sobre el cambio de claridad (ΔL) y morfologia superficial, mediante microscopia electronica de barrido (SEM) y resistencia al impacto. Todos los compositos experimentaron un incremento de claridad,no asi los de polipropileno 100 %. Independientemente del tamano de particula, el aumento de la proporcion de madera provoco una mayor modificacion de la claridad. Tambien se observo que los elaborados con particulas de madera malla 100 y fina tuvieron unincremento superior de la claridad. El microagrietamiento superficial ocurrio en el polipropileno 100 % y en los compositos polipropileno madera.Su severidad fue mayor con las particulas mas grandes y ligeramente mas notorio a 40 % y 50 % de madera. En todas lasformulaciones se perdio resistencia al impacto, menor en los compositos con particulas malla 60 a 30 % y 40 % de madera. Con una proporcion alta de particulas de madera, disminuyo notoriamente la resistencia al impacto. Las resistencias de todas las formulaciones de polipropileno-madera despues del intemperismo superaron a las del polipropileno puro.
What replication and localisation teach us: the case of semantic similarity measures

Repeating experiments is an important instrument in the scientific toolbox to validate previous work and build upon existing work. We present two concrete use cases involving key techniques in the NLP domain for which we show that reproducing results is still difficult. We show that the deviation that can be found in reproduction efforts leads to questions about how our results should be interpreted. Moreover, investigating these deviations provides new insights and a deeper understanding of the examined techniques. We identify five aspects that can influence the outcomes of experiments that are typically not addressed in research papers. Our use cases show that these aspects may change the answer to research questions leading us to conclude that more care should be taken in interpreting our results and more research involving systematic testing of methods is required in our field.
Analysis of Extreme Precipitation Events Using a Novel Data Mining Approach

An innovative data mining approach is presented and applied to investigate the climatic causes of extreme climatic events. Our approach comprises two main steps of knowledge extraction, applied successively in order to reduce the complexity of the original data set. The goal is to identify a much smaller subset of climatic variables that might still be able to describe or even predict the extreme events. The first step applies a class comparison technique. The second step consists of a decision tree learning algorithm used as a predictive model to map the set of statistically most significant climate variables identified in the previous step to classes of precipitation intensity. The methodology is employed to the study the climatic causes of two extreme events occurred in Brazil the last decade: the Santa Catarina 2008 extreme rainfall tragedy and the Amazon droughts of 2005 and 2010. In both cases, our results are in good agreement with analyses published in the literature.
A Comparative Analysis on Hijab Wearing in Malaysian Muslimah Magazines

This paper examines the renewed perception of Muslim women through the attributes of two Malaysian Muslimah (female Muslim) magazines. Through the years, Islamic magazines have evolved but the objective to enrich Muslim women with religious knowledge is inextricably maintained. An example is Nur, a popular monthly magazine with a focus on female modesty which has received positive response in the last decade. However, in June 2012, its publisher Karangkraf introduced Hijabista, a more “contemporary” Muslimah monthly amidst the proliferation of hijab trends in the global media. This new magazine aims to penetrate the urban community by emphasising on the fashionable and glamorous aspects of hijab wearing. As such, its stylish issues posed minimal discussions on religiosity and the role of hijab as a marker of piety. This paper applied a content analysis approach to interpret articles and related visuals produced by both Nur and Hijabista through the “framing” theoretical framework. Findings of the study revealed dissimilarities between the two magazines that were contributed by the growing preoccupation of the modern hijab. The mainstreaming of this hijab culture was presented largely in Hijabista through the recursive highlights on elite opinion leaders and fashion editorials of the hijab that are unfavourable to a conventional Muslimah. Findings also included analyses of predominant themes and messages that enhance the cultural hegemony of the modern hijab in the Malaysian media sphere.

Design and implementation of a stream-based visualization language

Information visualization tools are proliferating, with language and library-based visualization tools serving scientific, business and artistic endeavors. While partial formalizations of these tools exist, many details are unspecified. This leaves the tools as ad hoc implementations of ephemeral ideas. This thesis presents Stencil, a domain-specific language for specifying visualizations that has a well-founded basis. Stencil has a formal semantics that establish testable conditions for resource-bounded and deterministic execution. The semantics enable treatment of dynamic data in a principled fashion. Internal consistency of a visualization id defined in terms of these semantics and the implementation is shown to maintain that consistency. Stencil includes a task-parallel execution model that dramatically improves runtimes when working with dynamic data. The improvements are realized by application of the semantics to reason about the runtime, and employing persistent data structures to provide noninterference. As a domain-specific language, Stencil enables compact description of visualization programs. The key to providing this compactness is the Stencil compiler's ability to infer contextual information. Contextual inference avoids restatement of program constructs and allows guarantees about the inferred information. This contextual inference is used to create axes, legends and other guide structures in a fashion that is guaranteed to reflect both the corresponding analysis and the input data. The lessons learned developing the Stencil system are applicable to other visualization frameworks. For example, other libraries can employ the data structures implemented for Stencil. More importantly, the formalisms presented provide a basis to define and test properties of a visualization framework implementation. This thesis demonstrates the feasibility of treating visualization programs in a principled fashion and some of the benefits (including greater performance and reduced programming effort) of doing so.
Three words to tell a story: the movie poster tagline

The movie tagline is the film’s advertising slogan, usually printed on posters prior to the official release. It gives quick and catchy insight into themes, plot, and genre of the product it wishes to sell. This article explores the form, function, history, and rhetoric of the movie tagline. What is the relationship between tagline and poster image? What specific information do taglines give us about the films they advertise, and how do they convey this information stylistically and rhetorically? How do taglines differ, in their forms and functions, from one another? In answering these questions, the article gives credit to a long established yet frequently overlooked element of film advertising.

Performance evaluation of the pipe computer architecture

PIPE (Parallel Instruction and Pipelined Execution) is a high performance computer architecture with several features that make it well-suited for VLSI implementation. Special implementation features of the PIPE processor include an instruction cache and a pipelined implementation of both the instruction unit and the ALU. Special architectural features of PIPE include the architectural queues and the decoupled mode of execution. The goal of this study is to evaluate the performance of a PIPE computer system. We implemented a detailed, trace-driven performance simulator and a probabilistic model of the PIPE system for this study. Extensive simulation results on a set of hand-coded benchmarks are presented and analyzed. Various parameters and execution modes of the PIPE architecture are used in the simulation. Usefulness of architectural queues and decoupled architectures is demonstrated by the simulation results. Dependence of PIPE's performance on program characteristics, hardware speed, and system configuration is studied. We also investigate optimizing techniques suitable for the PIPE architecture and demonstrate them by examples. The simulator and the simulation results of this study can be used to guide the efforts in hardware implementation and software development for the PIPE architecture.
Feel the Heat: Emotion Detection in Arabic Social Media Content

The automatic detection of emotions in textual parts of social media websites such as Facebook and Twitter has applications for business development, user interface design, content creation, emergency response, among others. Current research has shown that it is possible to detect emotions for English content. To our knowledge, however, there are only few attempts for Arabic content. There is neither Arabic corpus with instances labeled for emotions, nor studies to detect emotions from Arabic microblogs content. Therefore, we collected Arabic text messages from the social networking website Twitter from January/February 2011. Human annotators labeled them with the corresponding emotions. Working with that corpus, our experiments show that emotions can be automatically detected from tweets after performing Arabic language related language preprocessing steps. Our contribution consists in adding preprocessing steps that have improved the classification results by 4.4% compared to the original Khoja stemmer. In addition, we have extracted a sample word-emotion lexicon from that corpus. Our experiment demonstrates that this sample word-emotion lexicon enhances the emotion detection results by 22.27% compared to the SMO classification using the train/test option. Finally, we show that the communication style used by the writer significantly relates with the emotion expressed in the text.
TMFab: A Transactional Memory Fabric for Chip Multiprocessors

With the performance of single-core processors approaching its limits, an increased amount of research effort is focused on chip multiprocessors (CMP). However, existing lock-based synchronization methods that are critical to performing parallel computation possess limited scalability and are inherently complex to use while programming. This thesis uses the concept of transactional memory implemented within a synthesizable fabric named TMFab, containing all the requisite hardware components needed to prototype a scalable chip-multiprocessor. Its processor independent nature enables the instantiation and use of any suitable soft-processor core inside the fabric without significant modifications to the fabric hardware. Additionally, the fabric offers scalability on account of its 3D interconnect architecture that supports die-stacking to add additional processor cores to the CMP without increasing its area footprint. The hardware transactional memory system of the fabric reduces performance overheads of transactional operations, allowing transactions to complete execution faster. TMFab is shown to provide speed up as high as 3.44x for correctly partitioned independent transactions and can be used to analyze the points of contention for conflicting transactions. The fabric was synthesized for both Field Programmable Gate Array (FPGA) as well as 90nm semi-custom targets.
Amélioration de la sécurité par la conception des logiciels web

L'internet est devenu un environnement omnipresent dans le monde du travail et du loisir. La popularite sans cesse croissante des applications web ainsi que des services associes entrainent l'execution de nombreuses transactions critiques, qui soulevent des questions de securite. Du fait de cette croissance, des efforts ont ete entrepris durant cette derniere decennie pour rendre les applications web plus sures. Malgre ces efforts, de recents rapports provenant de l'institut SANS estiment que plus de 60 % des attaques commises sur l'Internet ciblent les applications web en se concentrant sur les vulnerabilites inherentes aux problemes de validation, comme le Cross-Site Scripting ou les injections SQL. Dans cette these, nous avons conduit deux etudes de recherche empirique, analysant un grand nombre d'application web vulnerables. Nous avons assemble une base de donnees contenant plus de 10.000 rapports de vulnerabilites depuis l'an 2000. Ensuite, nous avons analyse ces donnees pour determiner si les developpeurs ont pris conscience des problematiques de securite web de nos jours, compare a la periode ou ces applications emergeaient. Puis nous avons analyse l'etroit lien entre le langage de programmation utilise pour developper l'application web et le nombre de vulnerabilite reporte. Avec ces resultats empiriques comme base, nous presentons notre solution IPAAS qui aide les developpeurs novice en termes de securite a ecrire des applications securisees par defaut. Nous montrons par ailleurs que cette technique ameliore de maniere probante la securite des applications web.
SCAFFOLDING COMPLEX TASKS BY OPEN ONLINE SUBMISSION: EMERGING PATTERNS AND PROFILES

Students in higher-education courses are often confronted with complex tasks that require application and integration of newly gained knowledge. Different students require different types and amounts of instructional scaffolding for coping with such challenging tasks. The incorporation of asynchronous online elements into academic courses offers various ways of implementing traditional instructional scaffolding methods, as well as the ability to incorporate new strategies made feasible by this medium.This paper presents and discusses the potential and challenges of using open online submission of assignments via asynchronous networking as a strategy for providing differential scaffolding in the preparation of complex tasks (not as an alternative model for online peer collaboration). A pilot study, performed with five graduate education courses, showed that open online submission of assignments led to spontaneous, informal peer-evaluation, enabling students to learn from peer examples. The detailed analysis of students’ activity and their reflections has revealed four typical learner profileswith respect to open assignment submission, self-evaluation and characteristic benefit from peer work.
Domain Adaptation for Statistical Machine Translation of Corporate and User-Generated Content

The growing popularity of Statistical Machine Translation (SMT) techniques in recent years has led to the development of multiple domain-speci c resources and adaptation scenarios. In this thesis we address two important and industrially relevant adaptation scenarios, each suited to different kinds of content. Initially focussing on professionally edited `enterprise-quality' corporate content, we address a speci c scenario of data translation from a mixture of different domains where, for each of them domain-specific data is available. We utilise an automatic classifier to combine multiple domain-specific models and empirically show that such a configuration results in better translation quality compared to both traditional and state-of-the-art techniques for handling mixed domain translation. In the second phase of our research we shift our focus to the translation of possibly `noisy' user-generated content in web-forums created around products and services of a multinational company. Using professionally edited translation memory (TM) data for training, we use different normalisation and data selection techniques to adapt SMT models to noisy forum content. In this scenario, we also study the effect of mixture adaptation using a combination of in-domain and out-of-domain data at different component levels of an SMT system. Finally we focus on the task of optimal supplementary training data selection from out-of-domain corpora using a novel incremental model merging mechanism to adapt TM-based models to improve forum-content translation quality.
