Distribución de quistes de Alexandrium catenella y otros dinoflagelados en sedimentos de la zona Sur-Austral de Chile

During the expeditions Cimar Fiordos 2, 3 and 4 (1996, 1997 and 1999), samples of marine sediments were collected in Southern Chile, between Melinka (Lat. 43o 45' S) and Beagle Channel (Lat. 54o 56' S) to study the distribution and abundance of dinoflagellate cysts, particularly the toxic dinoflagellate Alexandrium catenella. 22 Revista Ciencia y Tecnología del Mar, Vol. 27 (2) 2004 Samples were collected from 33 stations at depths of 1 to 15 meters. The study included photographic record and taxonomic identification of cysts to genus and, whenever possible, to species, with emphasis on the identification of cysts of A. catenella. Cysts from samples collected in cruises 3 and 4, were incubated in f/2-Se culture medium at 13 oC with controlled photoperiod (14:10, L:D), to induce germination and confirm species identification. Through this method, it was possible to establish monoclonal cultures of A. catenella. Cysts of dinoflagellates of at least 18 different forms or species were detected within the samples analyzed. The nine species of dinoflagellates identified belong to 5 genera (Protoperidium, Protoceratium, Scrippsiella, Polykrikos and Alexandrium). The cysts of A. catenella were present in samples of 11 stations. They were most abundant at estero Quitralco (Aysén Region), and at Puerto Engaño (Magallanes Region), with 76,7 ± 23,7 y 72,7 ± 33,8 cysts/mL, respectively. Environmental factors, including oceanographic and geographic conditions, and the characteristics of sediments, may affect the distribution and abundance of the cysts of A. catenella. Those locations may become sources for the generation of toxic blooms in the Aysén and Magallanes Regions.

DPLR also includes a large selection of generalized realistic surface boundary conditions and links to enable loose coupling with external thermal protection system (TPS) material response and shock layer radiation codes.
Task-based Evaluation Report: Building a Dutch Subjectivity Lexicon

We describe a method for creating a Dutch subjectivity lexicon based on an English subjectivity lexicon, an online translation service and a Dutch general purpose thesaurus: Wordnet. We use a PageRank-like algorithm to bootstrap from the Dutch translation of the English lexicon and rank the words in the Dutch thesaurus by polarity. Two versions of the Dutch Wordnet are used in the experiments: the 2001 version and the 2008 version developed within the Cornetto project. We present the evaluation results based on human assessment of the top 2000 negative words and the top 1500 positive words in the resulting lexicons. We find that using Cornetto results in a 7% improvement in accuracy. Between 70% to 86% of this improvement can be attributed to the larger size of Cornetto, the remaining improvement is attributed to the larger set of relations between words.
Systematic Phonics Instruction: Findings of the National Reading Panel.

Instruction for beginning readers is thought to be needed on several fronts, including phonemic awareness, phonics, fluency, reading comprehension, and vocabulary. The National Reading Panel reviewed the findings of many experiments to determine whether there was sufficient scientific evidence to indicate the effectiveness of these forms of instruction in helping students learn to read. This paper reviews one part of their report, that involving the evidence of systematic phonics instruction. The paper states that because the writing system in English is more complex and variable than in some languages, it is harder to learn, making systematic phonics instruction even more important to teach, because children will have difficulty figuring out the system on their own. It points out that a primary goal of phonics instruction is to teach students to read words in or out of text. It explains that phonics is a method of instruction that teaches students correspondence between graphemes in written language and phonemes in spoken language and how to use these correspondences to read and spell words. It notes that phonics instruction is systematic when the major graphemephoneme correspondences are taught and they are covered in a clearly defined sequence. According to the paper, the phonics review sought to determine whether there is experimental evidence showing that systematic phonics instruction helps children learn to read more effectively than unsystematic phonics instruction or instruction teaching little or no phonics and whether phonics instruction is more effective under some circumstances than others and for some students more than others. The paper discusses the 38 studies were reviewed in the meta analysis. Appended is a list of the 38 studies. (Contains 2 tables and 41 references.)

Interactive or Non-interactive? That Is the Question!!! An Annotated Bibliography.

When the Maryland Higher Education Commission made public a new state regulation distinguishing between interactive and non-interactive instruction, advocates of distance education objected. The staff of the commission undertook a bibliographic search to determine the effectiveness of various methods of delivering distance education. This article summarizes the results of the bibliographic search. Significantly, several studies reviewed suggest that interactive videodiscs may be the most effective form of instruction. The authors explore this possibility and propose a continuum of delivery modes from least interactive to most interactive. The logic of the continuum leads to a number of issues requiring further research. The annotated bibliography appears as an appendix to this issue. Lorsque la Maryland Higher Education Commission rend public un nouveau reglement de l'etat etablissant une distinction entre l'instruction interactive et non-interactive, les defenseurs de l'education a distance s'y opposent. Le personnel de la commission entreprend une recherche bibliographique afin de determiner l'efficacite de diverses methodes d'enseignement a distance. Cet article resume donc les fruits de cette recherche bibliographique. Fait tres revelateur, plusieurs etudes parcourues indiquent que les videodisques interactifs pourraient etre la forme d'enseignement la plus efficace. Les auteurs etudient cette possibilite, et proposent un continuum dans les modes d'enseignement, allant de peu d'interaction a beaucoup d'interaction. Cette progression logique mene a un certain nombre d'enjeux sur lesquels il faut egalement pousser la recherche. La bibliographie annotee figure en appendice du present numero.

Agentschappen en de verzelfstandigingsparadox

textabstractVerzelfstandiging van overheidsorganisaties leidt tot een paradox. Enerzijds krijgen de organisaties meer zelfstandigheid maar anderzijds krijgt het moederdepartement meer controle-mogelijkheden. Ook agentschappen hebben met deze paradox te maken. Sinds 1994 is het aantal agentschappen in Nederland toegenomen tot 22. In dit artikel wordt een beschrijving gegeven van de praktijk van interne verzelfstandiging, zoals het oprichten van agentschappen wordt genoemd. Naast een overzicht van taken en budgetten van agentschappen wordt ingegaan op het vraagstuk in hoeverre interne verzelfstandiging daadwerkelijk tot meer zelfstandigheid leidt. De ervaring met agentschappen laat zien dat de mate van zelfstandigheid evenveel zoniet meer afhankelijk is van afhankelijkheidsrelaties met het moederdepartement, omvang en andere kenmerken van agentschappen als van de formele bepalingen.
Integration of Information Management and Organizational Behavior: Lessons from Group-Based Teaching Experiences.

ABSTRACT This paper reports on observations from teaching an undergraduate information-based organization (IBO) course and builds on past research to explaip the findings in student issues, achievement motivation, and small-group effectiveness in information management teaching. The paper has three purposes: (1) to describe the development of a new course dealing with the integration of managerial and organizational behavior (OB) knowledge and information management (IM) knowledge; (2) to demonstrate the role and usefulness of groupwork in undergraduate teaching and its implications on motivation and learning; and (3) to discuss four stages of student motivation and intellectual development observed during the course. Two large sections of an undergraduate core course in information-based organizations (IBOs) were taught witn a teaching approach based on small group interactions (i.e., using in-class experiential exercises) and involving self-directed learning. The course had two goals: to introduce the students to management and OB principles, and to help them understand the role of IM, as well as information technology's (IT) impact on organizational structure, culture, change, _And development. Findings show that collaborative environments in the classroom induce much higher degrees of learning than environments based on the traditional teacher-dependent or lecture-based models. Furthermore, groupwork and role taking can both increase motivation and improve learning, enhance intellectual development and the confidence of the students, as well as increase the excitement and rejuvenation of the instructor. A chart outlines small group activities and their respective academic impacts, and a figure illustrates the stages of student intellectual development in the IBO course. (Contains 13 references.)

Integrating SOA into an enterprise architecture - A comparative analysis of alternative approaches

Enterprise Architectures have emerged as comprehensive corporate artefacts that provide structure to the plethora of conceptual views on an enterprise. The recent popularity of a service-oriented design of organizations has added service and related constructs as a new element that requires consideration within an Enterprise Architecture. This paper analyzes and compares the existing proposals for how to best integrate services into Enterprise Architectures. It uses the popular Zachman Framework as an example and differentiates the existing integration alternatives. This research can be generalized beyond service integration into an investigation onto how to possibly extend Enterprise Architectures with emerging constructs.
Writing Systems of the World

A pipe cleaning brush assembly for attachment to the rotatable face plate of a pipe facing machine for rotation therewith to clean the outer surface of a large diameter pipe section proximate the end thereof simultaneously with the machining of the pipe end face. The assembly includes a clamp having an inverted U-shaped member for placement over the edge of the face plate with a clamp jaw lock acting as a vise to grip the face plate and a clamp wedge lock engaging the face plate to resist centrifugal forces developed during rotation. A brush arm is pivotally mounted to the clamp, with a brush attached at one end and a cam at the other. The cam upon rotation causes the brush arm to pivot between a retracted position wherein the brush is held above the pipe surface to be cleaned and a position wherein the brush rests on the pipe surface.
Ability Estimation and Item Calibration Using the One and Three Parameter Logistic Models: A Comparative Study. Research Report 77-1.

Abstract : The literature on latent trait calibration procedures was reviewed to determine the methods available to calibrate dichotomous items for tailored testing applications. From the procedures, the most promising techniques for the calibration of items using the one- and three-parameter logistic models were selected for comparison. The maximum likelihood procedure developed by Wright and Panchapakesan was selected for the one-parameter model; and the estimation procedure for use with omitted responses, developed by Wood, Wingersky and Lord, was selected for the three-parameter model. The two procedures were then compared on their suitability for use with multivariate item pools, the sample size required for calibration, the effects of item quality, and the cost of calibration. Sixteen data-sets were used for these evaluations; eight live testing data-sets, and eight simulation data-sets generated to match specified factor structures. The one- and three-parameter models were found to estimate different components when the tests measured several independent factors. The three-parameter model estimated parameters from one of the factors, ignoring the others, while the one-parameter model estimated the sum of the factors.
Sorting batteries with deep neural networks - using deep belief networks and convolutionary neural networks for image classification.

This master thesis evaluates the possibilities of using di erent versions of deep Arti cial Neural Networks for identifying batteries at a battery sorting facility. GPU implementations of di erent versions of Deep Belief Networks and Convolutionary Neural Networks are evaluated on data sets made up by images of batteries. Di erent ways to get higher performance from the nets, in terms of percent correct classi ed, are then explored. The results suggest that the methods could be used to get a fast, and therefore industrial usable system, that can handle the identi cation of a large number of battery classes, with an error rate within the demands of the industry.
Produtividade da soja influenciada pela aplicação de doses de fertilizante com disco desencontrado e sulcador em um Latossolo sob plantio direto

O objetivo do trabalho foi relacionar a produtividade da cultura da soja com doses de fertilizantes e suas diferentes formas de aplicacao , em condicoes de plantio direto. O experimento foi conduzido com tres anos consecutivos em um Latossolo Vermelho distroferrico, em Maracaju, MS. As cultivares utilizadas foram: na safra 2000/2001, FT Jatoba; 2001/2002, CD 205 e na safra 2002/2003 Embrapa 48, ambas semeadas dentro do periodo recomendado para o zoneamento agricola para a regiao, em um delineamento experimental de blocos casualisados com cinco repeticoes. O experimento foi instalado na estacao experimental da Fundacao MS, em Maracaju, MS sobre uma area que estava ocupada com Brachiaria decumbens ha sete anos. Os tratamentos do experimento consistiram da combinacao entre dois sistemas de distribuicao do fertilizante na linha, com o uso do disco duplo desencontrado (disco defasado) e sulcador (botinha) e doses de adubacao: 0, 360, 480, 600 e 720 kg do formulado 3-28-16 por hectare. Apos a colheita, avaliou-se a produtividade por meio do peso de graos das parcelas colhidas. Concluiu-se que os diferentes sistemas de distribuicao do fertilizante nao afetaram a produtividade e que a cultura da soja responde significativamente ao aumento da adubacao NPK em solos com teores iniciais deste elemento relativamente baixos.
Audio and screen visual feedback to support student learning

Feedback has been highlighted as the most powerful influence on student achievement, but students are often less satisfied with feedback than with other aspects of the student experience. It is hence important that ways of offering feedback are found that are useful both for improving learning and for gaining student satisfaction. This ongoing study was designed to explore and to improve feedback in a variety of differing contexts, two of which are reported here: i) audio feedback on a first year undergraduate written assignment in Geography (product-oriented feedback); and ii) video feedback from ongoing laboratory sessions with first-year Biosciences students (process-oriented feedback). These contexts have been selected as offering different ways of working and for highlighting a number of issues and areas for further development. Student and staff views have been gained via surveys, focus groups, individual interviews and ‘stimulated recall’ sessions. Findings suggest that students have high expectations in relation to feedback; many anticipate the kinds of individual face-to-face interaction they experienced in school and are not easily satisfied by other ways of working. In addition, offering audio or video feedback that is supportive to learning in both affective and cognitive terms is not necessarily easy. In the context of written assignments there is still much to be learned about appropriateness of length, tone, the register of language, the balance between praise and criticism, and the best contexts and timing for audio feedback. In the context of large classes for laboratory sessions, further research is needed on how lecturers and demonstrators can give ongoing feedback that is useful when captured for replay in video form, and also about how effective video taken in class might be then used for training purposes in order to enable student demonstrators to be more effective and knowledgeable when offering feedback to students
A review of design science in information systems

This paper gives an appraisal of recent writings on design science in the information systems discipline. The authors believe that the new emphasis on design could be an insightful way to look at the discipline as long as the focus and emphasis of design science is broadened from a technical software engineering perspective to include and embrace the necessary social and organizational considerations. In addition, some potential confusions that surface in the recent design science publications are discussed, including conflating design activity with research. We argue that a reappraisal of some issues of concern may be required to ensure that design science fulfills its promise of building knowledge of design and improving practice in information systems.
Evaluating Website Quality in the Airline Industry

Recent media attention highlights the airline industry's need for a useful and valid instrument measuring website quality from a customer's perspective. This research develops and examines a Perceived Airline Website Quality Instrument (PAWQI) that attempts to provide some initial direction in this area. The Instrument contains four dimensions: site quality, information quality, interaction quality, and airline-specific quality. Development of the instrument incorporated a quality workshop as well as the adaptation of previously developed and validated instruments. The online survey - assessing Air New Zealand, Qantas, and Freedom Air - permitted an examination of the usefulness and validity of PAWQI by way of quantitative assessments, supplemented by qualitative data.
The computation of Fourier syntheses with a digital electronic calculating machine

Programmes have been devised for computing Patterson and Fourier syntheses in two and three dimensions with the EDSAC. An outline of the methods used is given and future possibilities are discussed. At present a two-dimensional summation of about 400 independent terms for about 2000 points takes'J1⁄2 hr. ; a three-dimensional summation of 2000 terms for 18,000 points takes 9 hr. A method~is"~lescribed whereby the EDSAC, without special modification, can be made to print results directly in contour form with considerable economy in time.
The Social Networks of High and Low Self-Monitors: Implications for Workplace Performance

This article examines how different personality types create and benefit from social networks in organizations. Using data from a 116-member high-technology firm, we tested how self-monitoring orientation and network position related to work performance. First, chameleon-like high self-monitors were more likely than true-to-themselves low self-monitors to occupy central positions in social networks. Second, for high (but not for low) self-monitors, longer service in the organization related to the occupancy of strategically advantageous network positions. Third, self-monitoring and centrality in social networks independently predicted individuals' workplace performance. The results paint a picture of people shaping the networks that constrain and enable performance.
User Information Satisfaction Scale Reduction: Application in an it Outsourcing Environment

The User Information Satisfaction (UIS) scale has evolved from the work of Bailey and Pearson (2) into a shortened form that is in use today. The UIS instrument has become a widely-used measure of satisfaction in information systems. Although the short-form measure introduced by Ives, Olson, and Baroudi (12) considerably decreased the size of the instrument, further improvements should be considered. This paper investigates a shortened version of the UIS instrument. Each of the thirteen items on the short-form of the instrument contains two measurement items. The current research analyzes each pair of responses per item and selects the one which is more highly correlated with an overall measurement of satisfaction. Results of the analyses provide support for the revised UIS instrument. Similar factor structures, high reliability, and similar regression results in both analyses indicate that the revised instrument is a suitable replacement for the traditional UIS scale.
