Can the Internet be used as a medium to evaluate knee angle?

Telemedicine promises to revolutionize medical care delivery in rural and remote areas. The ability to accurately evaluate physical impairment via the Internet is important to the possible future provision of Internet-based physiotherapy. This study evaluated the reliability and validity of assessing knee range of motion via the Internet. Two therapists evaluated knee angle on a single subject via two methods of assessment: the Internet and the traditional method (face-to-face). Nine random positions of the knee were chosen with the principal examiner performing 20 face-to-face and two sets of 20 Internet measures in each position (n=540). The secondary therapist performed Internet assessments only. The Internet connection was established at a readily available speed of 17 kbit/s. The Internet-based goniometer was found to be a valid tool for measuring both knee flexion and extension angles. It was shown to possess both high intra and inter-rater reliability. Difference average plots of the scores verified the consistency of measurement between both modes of assessment. The successful evaluation of the physical outcome measure of knee range of motion via the Internet assists the further development of Internet-based physiotherapy applications.

Phenotip - a web-based instrument to help diagnosing fetal syndromes antenatally.

Prenatal ultrasound can often reliably distinguish fetal anatomic anomalies, particularly in the hands of an experienced ultrasonographer. Given the large number of existing syndromes and the significant overlap in prenatal findings, antenatal differentiation for syndrome diagnosis is difficult. We constructed a hierarchic tree of 1140 sonographic markers and submarkers, organized per organ system. Subsequently, a database of prenatally diagnosable syndromes was built. An internet-based search engine was then designed to search the syndrome database based on a single or multiple sonographic markers. Future developments will include a database with magnetic resonance imaging findings as well as further refinements in the search engine to allow prioritization based on incidence of syndromes and markers.

The influence of the Internet on immunology education.

The potential of the Internet as a medium through which to teach basic and applied immunology lies in the ability to illustrate complex concepts in new ways for audiences that are diverse and often geographically dispersed. This article explores two collaborative Internet-based learning projects (also known as e-learning projects) that are under development: Immunology Online, which will present an Internet-based curriculum in basic and clinical immunology to Swiss undergraduate and graduate students across five campuses; and the OCTAVE project, which will offer online training to an international cadre of new investigators, the members of which are carrying out clinical trials of vaccines against HIV infection.

Teknologiat ja toteutustavat palvelukeskeiseen arkkitehtuuriin perustuvassa Internet-pohjaisessajärjestelmässä

Palvelukeskeiseen arkkitehtuuriin perustuvia järjestelmiä voidaan kehittää käyttämällä useita vaihtoehtoisia teknologioita. Toteuttamiseen parhaiten soveltuvia teknologioita ovat erilaiset standardikokoelmat, jotka tukevat useiden toisistaan toteutustavaltaan poikkeavien järjestelmien yhdistämistä käyttämällä standardeihin perustuvia rajapintoja. Täten kyseiset kokoelmat tukevat laajojen, useista erillisistä osista koostuvien palvelujärjestelmien kehittämistä. Tässä työssä selvitetään mikä palvelukeskeinen arkkitehtuuri on sekä millaisia komponentteja ja teknologioita kyseiseen arkkitehtuuriin perustuvan palvelujärjestelmän toteuttamiseen tarvitaan. Tavoitteena on esitellä palvelukeskeinen arkkitehtuuri ja siihen liittyvät teknologiat sekä suunnitella korkealla tasolla kyseisiä teknologioita hyödyntävä integraatioalusta käyttäjien ja useiden palvelun tarjoajien yhdistämiseksi. Työn tuloksena syntyvän teknologiaselvitysraportin selvitysluonteen vuoksi työssä ei suunnitella tarkasti toteutettavaa järjestelmää vaan ainoastaanpohjustetaan järjestelmän suunnittelua sekä esitellään siihen liittyviä arkkitehtuuri- ja toteutusmahdollisuuksia. Internet-pohjainen palvelukeskeiseen arkkitehtuuriin perustuva järjestelmä voi perustua suoriinverkon välisiin yhteyksiin tai vaihtoehtoisesti erityyppisiin välitason sovelluksiin. Välitason sovellukset mahdollistavat niiden tyypistä riippuen järjestelmän erilaisten lisäominaisuuksien toteuttamisen ja tukevat useita yleisimpiä palvelukeskeisiä teknologioita. Työn tuloksena syntyneen teknologiaselvityksen perusteella näistä teknologioista Web-palvelu -arkkitehtuuri ja siihen liittyvät menetelmät soveltuvat parhaiten suunniteltavan järjestelmän rakenneosiksi. Järjestelmän tarkemmat toteutustavat riippuvat myöhemmin määriteltävistä yksityiskohtaisista vaatimuksista sekä valittavasta välitason ohjelmiston toteutuksesta.

Uudet Internet -kehitysvälineet.

Internet asiakastarpeiden kartoituksessa tuotekehitykselle.

Diplomityö on tehty Lappeenrannan teknillisen korkeakoulun tuotantotalouden osastolla. Työ on osa Asiakastarpeiden kustannus- ja aikatehokas selvittäminen kansainvälisiltä markkinoilta (Kannasta) -projektia. Työn tarkoituksena oli tutkia Internetiä asiakastarvekartoituksessa. Työn tavoitteena oli kar-toittaa Internetin avulla käytettäviä asiakastarvetiedon lähteitä tuotekehitykselle ja esitellä Internetin avulla tapahtuvan asiakastarvetiedon keräyksen toimintatapa sekä tiedon keräyksen apuvälineet. Internetin avulla voidaan yrityksen liiketoimintaympäristöstä kerätä asiakastarvetietoja. Tietojen keräys voidaan tehdä kirjoituspöytätutkimuksena tai kvantitatiivis-kvalitatiivisena tutkimuksena. Internetin avulla tehtävässä kirjoituspöytätutkimuksessa tietoa asiakkaista, asiakkaiden tarpeista ja kilpailijoista voidaan kerätä World Wide Web -sivuilta tai tietopankeista. Kvantitatiivis-kvalitatiivisessa tutkimuksessa tietoja asiakkaiden tarpeista ja vaatimuksista kerätään Internet-työkaluilla yrityksen asiakkailta ja muilta sen sidosryhmiltä. Työssä on esitelty kolme eri asiakastarvekartoituksen Internet-työkalua. Internetin avulla saadaan parannettua yrityksen ja sen asiakkaiden välistä viestintää sekä tehostettua asiakastarvetiedon keräystä.

Increasing Industrial Customer Value through the Internet in Transportation Services

Tutkimuksen tavoitteena oli selvittää, kuinka sähköisiä palveluita tarjoamalla voidaan tuottaa asiakkaalle lisäarvoa yritysten välisessä kaupankäynnissä. Tarkastelunäkökulmana oli kuljetuspalveluita tarjoava yritys. Teoreettinen tutkimus pohjautui palveluiden markkinointiin, erityisesti palvelun laatuun, asiakkaan kokeman arvon lisäämiseen, asiakkaan odotuksiin, sekä Internetin välityksellä käytävään sähköiseen kauppaan. Kyselytutkimuksella selvitettiin lähinnä asiakkaiden odotuksia, koska sähköisiä palveluita ei vielä ole laajalti käytössä. Tutkimuksen mukaan asiakkaat kokivat useimmat ehdotetuista palveluista, kuten ajantasaisen reitti- ja aikataulupalvelun, tarkan lähtö- ja tuloinformaation, sekä konttien seurantapalvelun, lisäarvoa tuoviksi. Toisaalta yrityksen tarjoama uutispalvelu, tavaroiden tullaus ja keskustelufoorumi sähköisessä muodossa eivät tuntuneet luovan asiakkaille lisäarvoa.

Web based content and hybrid teaching: student perceptions of the effectiveness of using web based content and hyper-linked teaching units in teaching hybrid business and marketing post secondary classes /

This exploratory, descriptive action research study is based on a survey of a sample of convenience consisting of 172 college and university marketing students, and 5 professors who were experienced in teaching in an internet based environment. The students that were surveyed were studying e-commerce and international business in 3^^ and 4*'' year classes at a leading imiversity in Ontario and e-commerce in 5^ semester classes at a leading college. These classes were taught using a hybrid teaching style with the contribution of a large website that contained pertinent text and audio material. Hybrid teaching employs web based course materials (some in the form of Learning Objects) to deliver curriculimi material both during the attended lectures and also for students accessing the course web page outside of class hours. The survey was in the form on an online questionnaire. The research questions explored in this study were: 1. What factors influence the students' ability to access and learn from web based course content? 2. How likely are the students to use selected elements of internet based curriculum for learning academic content? 3. What is the preferred physical environment to facilitate learning in a hybrid environment? 4. How effective are selected teaching/learning strategies in a hybrid environment? The findings of this study suggest that students are very interested in being part of the learning process by contributing to a course web site. Specifically, students are interested in audio content being one of the formats of online course material, and have an interest in being part of the creation of small audio clips to be used in class.

Online Anonymity and the Kantian Publicity Principle: Can the Internet Solve the Paradox of Tyranny?

Immanuel Kant’s publicity maxim states that other-regarding actions are wrong if their maxim is not compatible with their being made public. This has the effect of forbidding dissent or rebellion against tyranny, since rebels cannot make their intentions and plans public. However, new internet technologies offer public speech from behind the “shield” of anonymity, allowing dissent to be public but preventing reprisals from tyrants. This thesis examines not only this possibility, but the value of internet-based discursive spaces for politics, their viability as a mode for political communication, and their implications for Classical and Enlightenment approaches to politics and intellectual virtue. Anonymous internet communications favour logos-based reasoning and discourse, which, in the liberal-democratic tradition, is preferable to phronesis and its attendant elitism and chauvinism. These technologies can open new vistas for liberal-democratic politics.

L'Internet et le droit international privé: un mariage boiteux ?

Quiconque aujourd’hui souhaitant profiter des avantages commerciaux d’Internet risque de faire face à une réalité juridique complexe. Qui peut rendre jugement d’un conflit né d’Internet ? Comment faire reconnaître un jugement rendu dans un autre pays ? Ces questions soulèvent beaucoup d’intérêt pour les juristes du cyberespace auqle l’auteur tente de répondre. Par des exemples concrets, notamment l’affaire Yahoo! et celle de Gutnick, l’auteur analyse également les relations entre Internet et le droit international privé. On voit donc les tendances qui se dégagent concernant les actes de dommage, la responsabilité et les victimes sur les réseaux et de quelle façon les cours internationales entendent les régler.

Data collection in Internet environment in social representations studies

The present study aimed at comparing social representations structures concerning data collection procedures: through internet forms, diffused in the WWW, and through conventional paper and pencil questionnaire methods. overall 893 individuals participated in the research, 58% of whom were female. A total of 217 questionnaires about the social representation on football (soccer) and 218 about the representation on aging were answered by Brazilian university students in classrooms. Electronic versions of the same instrument were diffused through an internet forum linked to the same university. There were 238 answers for the football questionnaire and 230 for the aging one. The instrument asked participants to indicate five words or expressions related to one of the social objects. Sample characteristics and structural analyses were carried out separately for the two data collection procedures. data indicated that internet-based research allows for higher sample diversity, but it is essential to guarantee the adoption of measures that can select only desired participants. Results also pointed out the need to take into account the nature of the social object to be investigated through internet research on representations, seeking to avoid self-selection effects, which can bias results, as it seems to have happened with the football social object.

Effects of a web-based personalized intervention on physical activity in European adults: a randomized controlled trial

Background: The high prevalence of physical inactivity worldwide calls for innovative and more effective ways to promote physical activity (PA). There are limited objective data on the effectiveness of Web-based personalized feedback on increasing PA in adults. Objective: It is hypothesized that providing personalized advice based on PA measured objectively alongside diet, phenotype, or genotype information would lead to larger and more sustained changes in PA, compared with nonpersonalized advice. Methods: A total of 1607 adults in seven European countries were randomized to either a control group (nonpersonalized advice, Level 0, L0) or to one of three personalized groups receiving personalized advice via the Internet based on current PA plus diet (Level 1, L1), PA plus diet and phenotype (Level 2, L2), or PA plus diet, phenotype, and genotype (Level 3, L3). PA was measured for 6 months using triaxial accelerometers, and self-reported using the Baecke questionnaire. Outcomes were objective and self-reported PA after 3 and 6 months. Results: While 1270 participants (85.81% of 1480 actual starters) completed the 6-month trial, 1233 (83.31%) self-reported PA at both baseline and month 6, but only 730 (49.32%) had sufficient objective PA data at both time points. For the total cohort after 6 months, a greater improvement in self-reported total PA (P=.02) and PA during leisure (nonsport) (P=.03) was observed in personalized groups compared with the control group. For individuals advised to increase PA, we also observed greater improvements in those two self-reported indices (P=.006 and P=.008, respectively) with increased personalization of the advice (L2 and L3 vs L1). However, there were no significant differences in accelerometer results between personalized and control groups, and no significant effect of adding phenotypic or genotypic information to the tailored feedback at month 3 or 6. After 6 months, there were small but significant improvements in the objectively measured physical activity level (P<.05), moderate PA (P<.01), and sedentary time (P<.001) for individuals advised to increase PA, but these changes were similar across all groups. Conclusions: Different levels of personalization produced similar small changes in objective PA. We found no evidence that personalized advice is more effective than conventional “one size fits all” guidelines to promote changes in PA in our Web-based intervention when PA was measured objectively. Based on self-reports, PA increased to a greater extent with more personalized advice. Thus, it is crucial to measure PA objectively in any PA intervention study.

LiLEDDA – a six step forum-based netnographic research method for nursing and caring sciences

Internet research methods in nursing science are less developed than in other sciences. We choose to present an approach to conducting nursing research on an internet-based forum. This paper presents LiLEDDA, a six-step forum-based netnographic research method for nursing science. The steps consist of: 1. Literature review and identification of the research question(s); 2. Locating the field(s) online; 3. Ethical considerations; 4. Data gathering; 5. Data analysis and interpretation; and 6. Abstractions and trustworthiness. Traditional research approaches are limiting when studying non-normative and non-mainstream life-worlds and their cultures. We argue that it is timely to develop more up-to-date research methods and study designs applicable to nursing science that reflect social developments and human living conditions that tend to be increasingly online-based.

Den litteraturvetenskapliga receptionsforskningen och internet : en metoddiskussion

Reader-Response Criticism and the Internet: A Methodological Discussion This article explores connections between Internet-based research and reader-response criticism, aiming to critically discuss the methodologies used in this particular field of research. First, the history of reader-response studies is briefly presented, with reference to theorists such as Richards, Rosenblatt, Robbe-Grillet, Iser and Jauss. It is noted that, for the past 15 years, people have utilised the Internet as a basis for the discussion of literary and reading-related topics. Researchers in this field may access reviews and commentaries on open web-based venues such as personal homepages, blogs and online forums (i.e. message boards and discussion sites). The material available on these sites is interesting because of its "spontaneous" nature; that is, such material has been formulated and uploaded without the interference of the researcher. The article presents one concrete example of an Internet-based reader-response study, discussing a number of pros and cons of the chosen methodology– including some important ethical considerations that arise when the researcher’s corpus is composed of material taken from the Internet. One of the conclusions of the paper is that many aspects of the general public’s web-based responses to literature are yet to be explored by the research community.
