Beaming into the rat world: enabling real-time intereaction between rat and human each at their own scale

Immersive virtual reality (IVR) typically generates the illusion in participants that they are in the displayed virtual scene where they can experience and interact in events as if they were really happening. Teleoperator (TO) systems place people at a remote physical destination embodied as a robotic device, and where typically participants have the sensation of being at the destination, with the ability to interact with entities there. In this paper, we show how to combine IVR and TO to allow a new class of application. The participant in the IVR is represented in the destination by a physical robot (TO) and simultaneously the remote place and entities within it are represented to the participant in the IVR. Hence, the IVR participant has a normal virtual reality experience, but where his or her actions and behaviour control the remote robot and can therefore have physical consequences. Here, we show how such a system can be deployed to allow a human and a rat to operate together, but the human interacting with the rat on a human scale, and the rat interacting with the human on the rat scale. The human is represented in a rat arena by a small robot that is slaved to the human"s movements, whereas the tracked rat is represented to the human in the virtual reality by a humanoid avatar. We describe the system and also a study that was designed to test whether humans can successfully play a game with the rat. The results show that the system functioned well and that the humans were able to interact with the rat to fulfil the tasks of the game. This system opens up the possibility of new applications in the life sciences involving participant observation of and interaction with animals but at human scale.

Expert clinical reasoning and pain assessment in mechanically ventilated patients: A descriptive study.

BACKGROUND: Pain assessment in mechanically ventilated patients is challenging, because nurses need to decode pain behaviour, interpret pain scores, and make appropriate decisions. This clinical reasoning process is inherent to advanced nursing practice, but is poorly understood. A better understanding of this process could contribute to improved pain assessment and management. OBJECTIVE: This study aimed to describe the indicators that influence expert nurses' clinical reasoning when assessing pain in critically ill nonverbal patients. METHODS: This descriptive observational study was conducted in the adult intensive care unit (ICU) of a tertiary referral hospital in Western Switzerland. A purposive sample of expert nurses, caring for nonverbal ventilated patients who received sedation and analgesia, were invited to participate in the study. Data were collected in "real life" using recorded think-aloud combined with direct non-participant observation and brief interviews. Data were analysed using deductive and inductive content analyses using a theoretical framework related to clinical reasoning and pain. RESULTS: Seven expert nurses with an average of 7.85 (±3.1) years of critical care experience participated in the study. The patients had respiratory distress (n=2), cardiac arrest (n=2), sub-arachnoid bleeding (n=1), and multi-trauma (n=2). A total of 1344 quotes in five categories were identified. Patients' physiological stability was the principal indicator for making decision in relation to pain management. Results also showed that it is a permanent challenge for nurses to discriminate situations requiring sedation from situations requiring analgesia. Expert nurses mainly used working knowledge and patterns to anticipate and prevent pain. CONCLUSIONS: Patient's clinical condition is important for making decision about pain in critically ill nonverbal patients. The concept of pain cannot be assessed in isolation and its assessment should take the patient's clinical stability and sedation into account. Further research is warranted to confirm these results.

Net communication strategy planning and management

Tutkielman tavoitteena on selvittää kuinka suunnitella ja hallita tehokasta verkkoviestintää, joka vastaa kohdeyleisön ja palvelun ylläpitäjien kasvaviin vaatimuksiin. Tutkielma on normatiivinen tapaustutkimus, jonka tuloksena syntyy konstruktiivinen askelmalli kokonaisvaltaisen verkkoviestintäprojektin toteuttamiseen. Tutkimus esittää myös teoreettisesti merkittävän näkökulman verkkopalvelujen sisällön hallintaongelmien ratkaisemiseen. Tosielämän verkkoviestintäprojektin toteutusta seurataan TietoEnator Forestissa, jossa tutkielman kirjoittaja työskentelee. Tutkimusmateriaalina käytetään 11 TietoEnator Forestissa toteutettua haastattelua, TietoEnator konsernin dokumentaatiota ja osallistuvaa havainnointia. Haastattelulomake sisältää 13 avointa kysymystä, jotka käsittelevät verkkoviestintästrategian perusasioita. Tunnistetut verkkoviestinnän avainmenestystekijät ovat vahva sisäinen sitoutuminen hajautettuihin ylläpitorooleihin ja perinpohjainen asiakastarpeiden tunnistaminen. Teknisesti on tärkeää, että eritason verkkoympäristöt, Internet, Intranet ja Extranet, hallitaan samoilla sisällönhallinta työkaluilla. Näin pystytään rationalisoimaan ylläpitotoiminnot.

Työminäkuva strategiaprosessissa. Case: Teknillinen korkeakoulu - Tietoliikenneohjelmistojen ja multimedian laboratorio

Tutkimuksen tavoitteena on selvittää työminäkuvan ja strategiaprosessin välistä yhteyttä laadullisen tutkimuksen keinoin. Tutkimus on luonteeltaan fenomenografinen eli se keskittyy selvittämään, miten ihmiset kokevat maailman ilmiöineen. Aineiston hankinnassa on hyödynnetty triangulaatiota eli ilmiötä tarkastellaan kolmen aineiston valossa. Aineistoa on kerätty haastatteluin, osallistuvalla havainnoinnilla sekä tutustumalla valmiisiin dokumentteihin, ja analysoitu koodaten ja luokitellen. Koska työntekijän ammatillinen identiteetti vaikuttaa hänen tapaansa ratkaista ongelmia ja tehdä päätöksiä, voidaan tutkimustuloksiin perustuen sanoa, että työminäkuva heijastuu strategiaprosesissa näkyvään ajatteluun ja käyttäytymiseen. Tulokset osoittavat myös, että strateginen työskentely kehittää työminäkuvaa edelleen. Resurssiperusteisen strategianmuodostuksen teoriaa soveltaen voidaan todeta olevan kyse jatkuvasta prosessissa, jossa kehitystä tapahtuu sekä organisaatio- että yksilötasolla

Financial Modeling to Support Organizational Control

Tutkimus tarkastelee taloudellisia mallintamismahdollisuuksia metsäteollisuuden liiketoimintayksikössä. Tavoitteena on suunnitella ja luoda taloudellinen malli liiketoimintayksikölle, jonka avulla sen tuloksen analysoiminen ja ennustaminen on mahdollista. Tutkimusta tarkastellaan konstruktiivisen tutkimusmenetelmän avulla. Teoreettinen viitekehys tarkastelee olemassa olevan informaation muotoilemista keskittyen tiedon jalostamisen tarpeisiin, päätöksenteon asettamiin vaatimuksiin sekä mallintamiseen. Toiseksi, teoria esittää informaatiolle asetettavia vaatimuksia organisatorisen ohjauksen näkökulmasta.Empiirinen tieto kerätään osallistuvan havainnoinnin avulla hyödyntäen epävirallisia keskusteluja, tietojärjestelmiä ja laskentatoimen dokumentteja. Tulokset osoittavat, että liikevoiton ennustaminen mallin avulla on vaikeaa, koska taustalla vaikuttavien muuttujien määrä on suuri. Tästä johtuen malli täytyykin rakentaa niin, että se tarkastelee liikevoittoa niin yksityiskohtaisella tasolla kuin mahdollista. Testauksessa mallin tarkkuus osoittautui sitä paremmaksi, mitä tarkemmalla tasolla ennustaminen tapahtui. Lisäksi testaus osoitti, että malli on käyttökelpoinen liiketoiminnan ohjauksessa lyhyellä aikavälillä. Näin se luo myös pohjan pitkän aikavälin ennustamiselle.

Web Content Customization

Tavoitteena on tutkia sisällön räätälöintiä Internetissä. Yritysten tarjoama sisällön määrä WWW-sivuillaan on kasvanut räjähdysmäisesti. Räätälöinnin avulla asiakkaat saavat juuri haluamaansa ja tarvitsemaansa sisältöä. Räätälöinti edellyttää asiakkaiden profilointia. Asiakastietojen kerääminen aiheuttaa huolta yksityisyyden menettämisestä. Tutkimus toteutetaan case-tutkimuksena. Tutkimuksen kohteena on viisi yritystä, jotka toimivat sisällön tarjoajina. Tutkimus pohjautuu valmiiseen aineistoon sekä osallistuvaan havainnointiin kohde yrityksistä. Sisällön räätälöinnistä voidaan havaita neljä eri perus lähestymistapaa. Profilointi toteutetaan pääsääntöisesti joko asiakkaan itse antamien tietojen pohjalta tai havainnoimalla hänen käyttäytymistään WWW-sivulla. Tulevaisuudessa tarvitaan selkeät pelisäännöt asiakastietojen keräämiseen ja käyttämiseen. Asiakkaat haluavat räätälöityä sisältöä, mutta sisällön tarjoajien on saavutettava heidän luottamuksensa yksityisyyden suojasta. Luottamuksen merkitys kasvaa entisestään, kun räätälöintiä kehitetään pidemmälle.

Learning journalistic opinion genres using CLIL methodology

The Faculty of Business and Communication recently started an internationalization process that, in two year’s time, will allow all undergraduate students (studying Journalism, Audiovisual Communication, Advertising and Public Relations, Business and Marketing) to take 25% of their subjects in English using CLIL methodology. Currently, Journalism is the degree course with the greatest percentage of CLIL subjects, for example Current Affairs Workshop, a subject dedicated to analyzing current news using opinion genres. Moreover, because of the lack of other subjects offered in English, ERASMUS students have to take some journalism subjects in order to complete their international passport, and one of the classes they choose is the Current Affairs Workshop. The aim of this paper is to explore how CLIL methodology can be useful for learning journalistic opinion genres (chat-shows, discussions and debates) in a subject where Catalan Communication students –with different levels of English- share their knowledge with European students of other social disciplines. Students work in multidisciplinary groups in which they develop real radio and TV programs, adopting all the roles (moderator, technician, producer and participants), analyzing daily newspapers and other sources to create content, based on current affairs. This paper is based on the participant observation of the lecturers of the subject, who have designed different activities related to journalistic genres, where students can develop their skills according to the role they play in every assignment. Examples of successful lessons will be given, in addition to the results of the course: both positive and negative. Although the objective of the course is to examine professional routines related to opinion genres, and students are not directly graded on their level of English, the Catalan students come to appreciate how they finally overcome their fear of working in a foreign language. This is a basic result of their experience.

Un estudi de cas: inclusió d'un infant amb paràlisi cerebral

En aquesta investigació qualitativa s’ha fet un estudi sobre la possibilitat d’incloure a un infant amb paràlisi cerebral en una escola ordinària. Per fer-ho, s’ha treballat a partir de l’estudi de cas d’un infant concret escolaritzat en un centre d’educació espacial. S’ha realitzat un anàlisi de la realitat d’aquest centre, l’Arboç, i de dos centres on les investigadores han realitzat l’estada de pràctiques, a l’escola Camí del Mig i a la Llàntia. Els instruments utilitzats al llarg del procés de recerca han estat les entrevistes, les graelles d’observació, el diari de camp i l’anàlisi de documents dels centres. Aquests s’han complementat amb una observació directa i participant a les escoles esmentades. La conclusió obtinguda després d’haver realitzat tot el procés d’investigació, és que la inclusió d’aquest infant no seria possible en els dos centres ordinaris estudiats, ja que seria necessari introduir un seguit de canvis a nivell d’infraestructures, metodologia, organització i de recursos humans i materials.

Evaluation of Implementation of BSc IT Curriculum at Tumaini University

In Tanzania computer knowledge is vital to supplement the pace fast growing economic and development activities, which demands high and reliable level of expertise in com- puting field. In 2006, a research carried out at Tumaini University with purpose to design and implement a contextualized curriculum that can supplement for such needs hence facilitate development in Tanzanian context. A contextualized curriculum took advantage of six principles namely curriculum contex- tualization, projects, practical, interdisciplinary orientation, international recognition and continuous research for the program’s formative and development. Implementation of the curriculum followed the CATI (Contextualize, Apply, Transfer, and Import) model with emphasis on students to identify societal expectations at the early stage in learning process, in which case the graduates will potentially cater for societal expertise needs on ICT. This study adopts an emergent exploratory cross-section research design, while employ- ing a qualitative approach. This study was conducted at Tumaini University in Iringa where by purposeful sampling was used to obtain participants such as students, teach- ers, administrators and employers who participated in several focus group discussions, in-depth interviews and participant observation. The study reveals that six principles are satisfactorily met,despite of bottlenecks such as incompatibility in pedagogical thinking and technology availability for e-learning, learning attitudes, insufficient experts with actual skills and experience,in academic field among the others. The study recommends that iterative longitudinal study should be car- ried out to design for proper intervention in response to these problems which will help in improving and stabilize the curriculum.

Estudio multidisciplinario del ecosistema manglar en la comunidad tradicional de Curral Velho : Análisis de los servicios ecosistémicos producidos por los manglares a partir de la percepción de la comunidad de Curral Velho

Existe un número elevado de sectores de la sociedad que identifican los beneficios ofrecidos por el ecosistema del manglar así como la interacción entre ellos y el bienestar humano. Aún así, los servicios ecosistémicos (ESs) ofrecidos por la naturaleza son poco visibles y reconocidos legislativamente. Se puede observar que el manglar es uno de los ecosistemas más productivos del planeta. Tienen gran importancia tanto económica, social, ambiental como cultural, pero en las últimas décadas se ha hecho más notable una degradación progresiva debida, en gran parte, a la cría de camarón en cautividad, la camaronicultura. Por esta causa, se observa que la legislación y las políticas que pretenden gestionar estos ecosistemas, no actúan en consecuencia al no imponer ciertas medidas necesarias para esta vital protección, ni considera la importancia de los ecosistemas para la vida de las comunidades tradicionales que dependen de sus servicios para sobrevivir. Por ello es necesario producir un conocimiento sobre ESs a partir de la percepción por parte de la comunidad y que la comunidad se implique en la resolución de esta problemática, ya sea en la toma de decisiones o mediante ciertas actividades o acciones que puedan denunciar estas prácticas insostenibles. Frente a este contexto, este trabajo fue realizado a partir de la información obtenida en la comunidad de Curral Velho (Ceará, Brasil), con el objetivo de realizar un estudio sobre los ESs proveídos por los manglares a partir de la percepción de la comunidad para demostrar la importancia que éstos tienen para el bienestar de los habitantes de la comunidad que se benefician. Los resultados fueron alcanzados a partir de una combinación de metodologías sociales que hacen posible la participación por parte de los habitantes: free listing, encuestas de valoración, grupos focales y observación participante. En la aplicación de estos métodos fueron identificados nuevos ESs de carácter psicológico por los pescadores/as de la pesca artesanal. Por lo que se concluye que es importante tener en cuenta la opinión de las comunidades adyacentes para preservar los flujos ecosistémicos que proporciona el manglar.

Diretrizes para a formação de professores da educação básica em interface com a licenciatura em química: em contexto as possibilidades formativas

We developed and applied an educational instrument (ID) to discuss, in the discipline of Supervised Pre Service Teachers Practice 1, guidelines for teacher education to redefine teacher knowledge with a specific focus on chemistry teachers. The study used methodological fundamentals of Discursive Textual Analysis that involves identifying and isolating a set of materials subjected to analysis, categorizing these statements and producing texts, integrating these descriptions and interpretations, basing its construction on the category system built. Data were collected through participant observation and text readings used by the students in performing the activity. It was noted that the chemistry teachers trained were able to express opinions that indicated the Construction of Meanings Interface that was the category of analysis established a priori.
