Työnkulkukoneen soveltuvuus sähköisen huutokauppajärjestelmän toteutuksessa

Sähköiset huutokaupat ovat virtuaalisia markkinapaikkoja, jotka sijaitsevat jossain päin internetiä. Sähköistä huutokauppaa käydään yritysten välillä (B2B), yritysten ja kuluttajien välillä (B2C) sekä kuluttajien kesken (C2C). Tässä työssä sähköisellä huutokaupalla tarkoitetaan ensin mainittua, yritysten keskinäistä kaupankäyntiä. Työn tarkoituksena on tutkia työnkulkukoneen soveltuvuutta sähköisen huutokauppajärjestelmän moottorina. Työssä perehdytään avoimen lähdekoodin ActiveBPEL-koneeseen, ja tutkimus tapahtuu suunnittelemalla, mallintamalla ja testaamalla liiketoimintaprosessi, joka rekisteröi ostajan ja myyjän tiedot järjestelmään. Toteutettava prosessi on yksi osa sähköistä huutokauppaa, mutta saman periaatteen mukaisesti olisi mahdollista toteuttaa myös kokonainen huutokauppa. Tässä työssä tarkastellaan sähköistä huutokauppaa, joka perustuu web-palveluihin, ja jolla on selvä koordinaattori. Koordinaattori ohjaa toisia mukana olevia web-palveluja ja niiden ajettavia operaatioita. Korkean tason mallit kuvataan BPMN-notaation avulla, itse prosessi toteutetaan BPEL-kielellä. Prosessin mallinnuksessa ja simuloinnissa käytetään apuna ActiveBPEL Designer -ohjelmaa. Työn tavoitteena on paitsi toteuttaa osa huutokaupasta, myös antaa lukijalle käsitys siitä liiketoimintaympäristöstä, johon huutokauppa kuuluu, sekä valottaa huutokaupan taustalla olevia teknologioita. Erityisesti web-palvelut ja niihin liittyvät käsitteet tulevat lukijalle tutuiksi.

Innovar, renovar, avaluar

[eng] The new educational context in which we are involved and the facilities of the TIC (Communication Information Technologies) have led to the necessary modification of didactic approach that during years has been used for Pharmaceutical Technology teaching. However, changes/updating and innovation require a simultaneous reflection in order to avoid excessive dispersion of the approach and to channel adequately the pedagogic and didactic effort. On the other hand, it is necessary to evaluate the above initiatives to determinate if these one are on the right track. The Pharmaceutical Technology Teaching Innovation Group of the University of Barcelona has been formed and consolidated in this point of view. In this work, a review of studies carried on by the group, in the exposed purposes, from the beginning of their activities is presented. [spa] El nuevo contexto docente en el que estamos inmersos así como las posibilidades de las TIC (Tecnologías de la Información y de la Comunicación) han conllevado la necesaria modificación de los planteamientos didácticos que durante años han servido de base para las enseñanzas de la Tecnología Farmacéutica. Sin embargo, la renovación/actualización e innovación precisan de una simultánea reflexión a fin de evitar una excesiva dispersión del enfoque y para encauzar adecuadamente el esfuerzo pedagógico y didáctico. Por otra parte, es necesario evaluar dichas iniciativas para determinar si están bien encaminadas. El Grupo de Innovación Docente de Tecnología Farmacéutica de la Universidad de Barcelona se ha creado y consolidado desde esta óptica. En este trabajo se presentan un conjunto de estudios que el grupo ha llevado a cabo, con los fines expuestos, desde el comienzo de sus actividades.

Discursos crítics, pràctiques ètiques. Repensant la funció docent a la Universitat

El nexe d'unió com a professores va ser a partir de la preocupació i reflexió que anavem compartint sobre les nostres practiques a l'aula. El que sovint ens preguntavem era com podíem assumir el compromís perqué els nostres pressuposits educatius no ens tra'issin a I'hora de posar-los a la practica. La recerca d'aquesta coheréncia va fer-nos plantejar, analitzar i compartir els nostres suposits, sobretot pel que fa al sentit i a la visió del coneixement que transmetem relacionats amb un tipus determinat d'entendre la practica, és a dir, d'entendre les relacions amb I'alumnat, el tipus de tasques que es realitzen a classe i els processos d'avaluació que portem a terme. El que plantejarem a continuació és fruit, com hem dit, de les converses i reflexions que periodicament compartíem, pero també de les valoracions que, de manera anomina, realitzava I'alumnat de les nostres classes i d'algunes observacions que ens féiem mútuament. Agruparem les nostres reflexions a partir d'explorar tres temes: la transmissió del saber, I'enfocament pedagogic de la practica i les dificultats o limitacions d'uns estils determinats d'ensenyanya.

Innovatiivisen virtuaaliyhteisön edellytykset

Tutkielmassa tutkittiin innovatiivisen virtuaaliyhteisön toiminnan edellytyksiä. Teoreettinen viitekehys muodostui virtuaaliyhteisöjen, innovatiivisuuden ja luovuuden tarkastelusta. Tutkielman empiirisessä osuudessa käytettiin kvalitatiivista tutkimusotetta. Tutkimusaineisto perustui internetiin tutkimusta varten perustetun innovointiin keskittyneen keskustelufoorumin tuottamiin tuloksiin sekä ko. foorumin käyttäjien palautteeseen. Tutkimuksessa kävi ilmi, että innovatiivisuus vaatii motivoitumista käsiteltävään aiheeseen. Ideoijan täytyy kokea aihe mielenkiintoiseksi, jotta virtuaaliyhteisössä tapahtuva innovointi pystyy tarjoamaan parhaan etunsa eli välineen ajasta ja paikasta riippumattomaan ideointiin. Virtuaaliyhteisöllä tulee olla koordinaattori, joka pitää huolen tiedon kokoamisesta, yhteenvedoista ja ruokkii yhteisön aktiivisuutta. Yhteisössä innovoiminen edellyttää yhteisön ilmapiirin rakentamista otolliseksi avoimelle viestinnälle. Tämä syntyy rakentamalla luottamusta toimijoiden välille mm. kannustamalla sosiaaliseen viestintään. Virtuaaliyhteisössä passivoituminen on suuri uhka. Virtuaaliyhteisöä täytyy johtaa kannustaen ja pitäen kaikin keinoin huolta jäsenten aktiivisen keskustelun ylläpidosta. Passiivisuus aiheuttaa yleistä passiivisuutta, aktiivisuus nostaa aktiivisuutta. Toimijoiden anonyymius voi olla yhteisön voimavara, mutta tuo sitoutumattomuutta, jolloin mikä tahansa häiritsevä tekijä saa aikaan sen, että toimija voi jättää osallistumatta asian käsittelyyn ilman muualta kohdistuvia paineita. Anonyymiyden hyödyt ja haitat tulee punnita tarkoin.

Anàlisi de la figura de coordinador/a TIC a deu escoles vallesanes: Funcions, formació i perfil

La present recerca és un estudi de cas de la figura del coordinador/a TIC (Tecnologies de la Informació i la Comunicació) centrant-se en aspectes referents a les funcions, la formació i el perfil. El constant avenç tecnològic en la societat també inclou el món educatiu i això crea la necessitat de tenir una figura dinamitzadora de les TIC dins l’escola, un punt de referència. Amb l’objectiu d’aconseguir conèixer aquesta figura es dissenya i s’aplica un qüestionari amb el qual s’obtindrà informació d’aquesta figura tractant temes que van tant dels esmentats anteriorment com de la comissió TAC o dels recursos TIC que disposen. Per poder obtenir aquesta informació es compta amb la participació de deu escoles vallesanes. Els resultats mostren que el tipus de funció que més realitza són les Tècniques mentre que les de Lideratge són les que menys. Mostren també com la formació que es demana és tècnica i pedagògica i que el perfil dels coordinadors/es TIC és bastant divers. En conclusió, es pot dir que la figura del coordinador/a TIC de centre és un punt clau dins l’escola ja que ajuda a la inclusió digital, entre d’altres aspectes, però encara és una figura molt ambigua.

The practical application of e-Portfolio at the Open University of Catalonia : assessment of competence based learning

The paper presents the results of the piloting or pilot test in a virtual classroom. This e-portfolio was carried out in the 2005-2006 academic year, with students of the Doctorate in Information Society, at the Open University of Catalonia. The electronic portfolio is a strategy for competence based assessment. This experience shows the types of e-portfolios, where students show their work without interactions, and apply the competence-based learning theories in an interactive portfolio system. The real process of learning is developed in the competency based system, the portfolio not only is a basic bio document, has become a real space for learning with competence model. The paper brings out new ideas and possibilities: the competence-based learning promotes closer relationships between universities and companies and redesigns the pedagogic act.

VIX as a stock market indicator

The goal of this research was to make an overall sight to VIX and how it can be used as a stock market indicator. Volatility index, often referred as the fear index, measures how much does it cost for investor to protect his/hers S&P 500 position from fluctuations with options. Over the relatively short history of VIX it has succesfull timing coordinator and it has told about the market state adding its own psychological view of the amount of fear and greed.

The Detector Control Systems for the CMS Resistive Plate Chamber at LHC

The RPC Detector Control System (RCS) is the main subject of this PhD work. The project, involving the Lappeenranta University of Technology, the Warsaw University and INFN of Naples, is aimed to integrate the different subsystems for the RPC detector and its trigger chain in order to develop a common framework to control and monitoring the different parts. In this project, I have been strongly involved during the last three years on the hardware and software development, construction and commissioning as main responsible and coordinator. The CMS Resistive Plate Chambers (RPC) system consists of 912 double-gap chambers at its start-up in middle of 2008. A continuous control and monitoring of the detector, the trigger and all the ancillary sub-systems (high voltages, low voltages, environmental, gas, and cooling), is required to achieve the operational stability and reliability of a so large and complex detector and trigger system. Role of the RPC Detector Control System is to monitor the detector conditions and performance, control and monitor all subsystems related to RPC and their electronics and store all the information in a dedicated database, called Condition DB. Therefore the RPC DCS system has to assure the safe and correct operation of the sub-detectors during all CMS life time (more than 10 year), detect abnormal and harmful situations and take protective and automatic actions to minimize consequential damages. The analysis of the requirements and project challenges, the architecture design and its development as well as the calibration and commissioning phases represent themain tasks of the work developed for this PhD thesis. Different technologies, middleware and solutions has been studied and adopted in the design and development of the different components and a big challenging consisted in the integration of these different parts each other and in the general CMS control system and data acquisition framework. Therefore, the RCS installation and commissioning phase as well as its performance and the first results, obtained during the last three years CMS cosmic runs, will be

Aportaciones del área de educación física a la competencia básica "aprender a aprender"

In front of a moment of change in the education, with the entry into force of the LOE (Ley Orgánica de Educación, 2006), the aim of thisarticle is to face the challenge of trying to answer to the need to make concrete learning agreements with the new curriculum based on competences.The present article arises from the interest of being able to offer an approach that facilitates the exposition to show the didactic units from the areaof physical education in relation with the pedagogic principles of the LOE. Departing from this commitment, let’s sense beforehand an offer of thecontributions of the Physical Education to the Basic Competence to learn to learn which entails to develop some capacities in fuction of knowing todo skills

Implantação das diretrizes curriculares nacionais para formação de professores de química em uma instituição federal de ensino superior: desafios e perspectivas

The Curricular Proposals for Chemistry Teaching Courses aim at producing a reflexive-researcher teacher, who will be able to deal with cross-disciplinary subjects. The challenge faced by the majority of the federal universities, in implementing these guidelines, is to attain these objectives inside their departmental structure. We present here the formulation of the Chemistry Teaching Course Pedagogic Project from Federal University of Pelotas concerning on the CNE/CP 1/2002 and 2/2002 Resolutions. We discuss the impact of these Proposals, the difficulties faced and the new perspectives of organization inside of these institutions, which resulted in new spaces with cross-disciplinary and cross-departmental orientation.

Percepção dos pós-graduandos em química da Universidade Federal de Minas Gerais sobre a própria formação docente

The pedagogic training of university professors has been overlooked in institutions of higher education. In the second semester of 2009, students of the Graduate Chemistry Program at the Federal University of Minas Gerais participated in an investigation that aimed to evaluate the students' perceptions of their own training to become professors. It was found that a large number of students felt prepared to teach at institutions of higher education, despite their lack of experience at this education level. A significant point in this work was the finding that most students do not acknowledge the need of associating the teaching practice with teaching-learning theories, but instead consider the knowledge of scientific content important.

O CONHECIMENTO PEDAGÓGICO DOS DOCENTES DE QUÍMICA DO ENSINO SUPERIOR

This study aims to investigate the pedagogical knowledge of Higher Education Chemistry teachers. From the perspective of qualitative research, questionnaires were given, there was documentary analysis and were interviewed twenty-six teachers of the Institute of Chemistry of an institution of state public higher education of São Paulo. Discussed the relevance of pedagogic disciplines in Postgraduate courses and participation in monitoring programs and teacher training in higher education teacher formation. It was found that most teachers lack pedagogical training and some do not show interest in the subject, but look for ways to overcome the difficulties encountered. The results obtained demonstrate the urgency to rethink and reorganize the PostGraduate courses before the real need for training of teachers for higher education.

Is it possible to utilize VIX for a profitable trading strategy of S&P 500 Index?

The goal of this research was to make an overall sight to VIX® and how it can be used as a stock market indicator. Volatility index often referred as the fear index, measures how much it costs for investor to protect his/her S&P 500 position from fluctuations with options. Over the relatively short history of VIX it has been a successful timing coordinator and it has given incremental information about the market state adding its own psychological view of the amount of fear and greed. Correctly utilized VIX information gives a considerable advantage in timing market actions. In this paper we test how VIX works as a leading indicator of broad stock market index such as S&P 500 (SPX). The purpose of this paper is to find a working way to interpret VIX. The various tests are made on time series data ranging from the year 1990 to the year 2010. The 10-day simple moving average strategy gave significant profits from the whole time when VIX data is available. Strategy was able to utilize the increases of SPX in example portfolio value and was able to step aside when SPX was declining. At the times when portfolio was aside of S it was on safety fund like on treasury bills getting an annual yield of 3 percent. On the other side just a static number’s of VIX did not work as indicators in a profit making way.

Kielikylpydidaktiikkaa kehittämässä : 3-6-vuotiaiden kielikylpylasten kielellinen kehitys ja kielikylpydidaktiikan kehittäminen päiväkodissa

The goal of this study is to determine the naming ability in Finnish and Swedish of nursery school-aged children participating in a language immersion programme, as well as their command of both languages. The study also aims to describe factors reflecting language immersion teaching in nursery schools based on action research and a literature survey. The longitudinal study, conducted in 2003–2005, comprised 133 native Finnish three- to six-year-old children in language immersion programmes. A total of four measurements were carried out over two and a half years. In each measurement, four separate tests were given to each child (totally 1134 measurements). Research material was collected using survey tools that measured the children’s naming ability and command of language. The tools had been translated into both Finnish and Swedish. The material also includes taped responses related to the tool for naming ability. Didactic approaches were developed on the basis of material from action research and the literature survey. The material was examined using methodological triangulation, and a quantitative analysis was made of each survey tool. Furthermore, a content analysis of the children’s taped responses gave further depth to the description of language development. The theoretical framework of the study is mainly based on modern sociocultural theories of second language development and acquisition. Thus, the approach is both linguistic and pedagogic, with emphasis lying on the latter. The socioculturally-oriented framework of this study is mainly influenced by the theorists Vygotski, Spolsky, van Lier and Cummins. According to the results, the language skills of children in language immersion programmes develop as expected from age three to six in the fields studied. In the field of language command, the children acquired excellent skills in listening comprehension. Their naming ability was not as good. In each test, the children showed weaker skills in Swedish than in Finnish. However, based on the assumption that the two languages have a shared cognitive field, the skills in Swedish catch up with the skills in Finnish at an annual rate of 6–7 per cent. The study indicates that children meet a language development threshold one year earlier in their native language than they do in the immersion language. As for the naming ability in Swedish, problems arose from the fact that the deviation in results increases with age. Children showed creativity in their use of naming strategies. Judging by the research results, children begin to use the immersion language as a tool for thought at a very early phase. The research results, action research and literature survey were also used to create a general educational model for language immersion.

Det pedagogiska övervägandet : en uppmärksamhetsriktande studie i och genom humanvetenskaplig handlingsteori

Det övergripande syftet med avhandlingen är att bidra till en handlingsinriktad diskurs. Ambitionen är att rikta uppmärksamheten mot den pedagogiska övervägande handlingen genom att pröva konkreta exempel från en pedagogisk praktik mot en begreppsapparat inspirerad av den humanvetenskapliga handlingsteorin. Forskningsfrågorna lyder: Vad är en övervägande handling? Hur byggs den upp och vad förutsätter den? Bakgrunden till intresset att belysa den övervägande handlingen är en önskan att överbrygga klyftan mellan teori och praktik och att hitta ett sätt att samtala om ”tyst kunskap” och den konkreta pedagogiska verkligheten så att denna kan utvecklas på ett meningsfullt sätt. Förhållandet mellan intentionalitet och instrumentella handlingar är av särskilt intresse. Den aristoteliska begreppsapparaten som avser att belysa den mänskliga handlingen används i studien som både utgångspunkt och analysredskap. Retoriken ses som den vetenskap som kan beskriva och förklara hur vi skapar mening med hjälp av språket. Fyra fokussamtal med sammanlagt fem studerande på musikanimatörutbildningen genomfördes under vårterminen 2006. Referaten från samtalen bearbetades till en berättelse. I konstruktionen av berättelsen användes dels en fenomenologisk analys, dels narrativ bearbetning. De aristoteliska begreppen poíesis, praxis och theoria tillämpades och prövades på berättelsen varefter en retorisk analys genomfördes. Berättelsen visar två konkurrerande praxis. Utbildningen framstår i berättelsen dels som en horisontell ”alla kan”-utbildning, dels som en vertikal och lärarstyrd verksamhet. Berättelsen ger inte så många exempel på pedagogiska överväganden men tydliggör ändå den övervägande handlingen. Det pedagogiska övervägandet innebär ett väljande utifrån teoretiskt tänkbara och med praxis förenliga handlingsalternativ. Reflektion ingår i övervägandet men är inte detsamma som övervägande. Övervägandet är inte enbart en rationellt kalkylerande aktivitet. Holistiska och intuitiva procedurer är en viktig del i processen. Övervägande förutsätter dessutom ansvar.
