Tässä tutkimuksessa tarkastelen seksiin liittyviä viestejä, joita 11–18-vuotiaat tytöt ovat vastaanottaneet ja lähettäneet internetissä. Aineisto on kerätty kyselytutkimuksella, johon vastasi 1269 suomalaista, internetiä aktiivisesti käyttävää nuorta. Julkisessa keskustelussa lasten internetissä saamat seksiin liittyvät yhteydenotot tuomitaan haitallisiksi. Lähettäjien epäillään yleensä olevan aikuisia. Aineiston analyysi kuitenkin osoittaa, että haittojen lisäksi tyttöjen nettiseksikulttuuriin kuuluu paljon positiivisiksi koettuja asioita. Tytöt esimerkiksi pelaavat keskenään seksuaalissävytteisiä roolipelejä, harrastavat nettiseksiä omana itsenään, juttelevat toisten kanssa kokemuksista ja oppivat lisää seksiin liittyvistä asioista. 65 prosenttia tutkituista tytöistä on vastaanottanut seksiin liittyviä viestejä internetissä. Itse niitä on lähettänyt 20 prosenttia vastaajista. Tytöt ovat saaneet viestejä niin toisilta nuorilta kuin aikuisiltakin. Osa viesteistä koetaan epämiellyttävinä, osa mukavina ja osa vitseinä. Merkittävä osa vastaajista ei pohdi viestejä sen tarkemmin: Ne koetaan luonnolliseksi osaksi nettikulttuuria tai niiden ajatellaan olevan harmittomia. Aineiston analyysin lisäksi tutkimuksessa käsitellään lasten netinkäyttöön liitettyjä riskejä, jotka liittyvät jollakin tavalla seksiin. Näitä ovat esimerkiksi pedofilia ja lapsipornokuvat. Aiempaa tutkimusta keskustelutetaan aineiston kanssa. Erityisenä keskustelukumppanina käytetään EU Kids Online -projektin tutkimuksia niin Suomesta kuin muistakin Euroopan maista.

The effects of Crypthecodinium cohnii (Cryp.), Chlorela spp. (Chlo.) and Isochrysis galbana (Iso.) addition to milk replacer on goat kids and lambs growth were evaluated. About 80 Majorera goat kids (males and females) and 80 Canarian sheep lambs were randomly assigned into four different groups (by specie) according to diet. Control groups were fed with a commercial milk replacer at 16% (w/w); Cryp. groups received a commercial milk replacer (15.1% w/w) supplemented with 9 g of a paste of C. cohnii; Chlo. groups received a commercial milk replacer (15.1% w/w) supplemented with 9 g of a paste of Chlorela spp.; Iso. groups received a commercial milk replacer (15.1% w/w) supplemented with 9 g of a paste of I. galbana. After colostrum period, animals were individually bottle-fed twice daily (8 am and 8 pm) ad libitum with the corresponding diet until day 60 of life. Animals were weighted every week at 8 am and liquid diet intake was recorded weekly. No effects of microseaweed addition were observed, neither growth nor milk replacer intake.

Most accounts of child language acquisition use as analytic tools adult-like syntactic categories and schemas (formal grammars) with little concern for whether they are psychologically real for young children. Recent research has demonstrated, however, that children do not operate initially with such abstract linguistic entities, but instead operate on the basis of concrete, item-based constructions. Children construct more abstract linguistic constructions only gradually – on the basis of linguistic experience in which frequency plays a key role – and they constrain these constructions to their appropriate ranges of use only gradually as well – again on the basis of linguistic experience in which frequency plays a key role. The best account of first language acquisition is provided by a construction-based, usage-based model in which children process the language they experience in discourse interactions with other persons, relying explicitly and exclusively on social and cognitive skills that children of this age are known to possess.

Nos dias de hoje, uma empresa não pode desenvolver um negócio sustentável limitando-se à oferta de um produto, é necessário compreender que muitas vezes o cliente recorre ao consumo de determinado bem devido ao serviço ao cliente que este tem associado (Grönroos, 2007). As empresas atualmente deparam-se com uma concorrência no serviço ao cliente prestado, sendo que a difusão da informação tecnológica e o aumento do uso de internet oferece às empresas oportunidades de desenvolver a sua oferta de serviço ao cliente e de se diferenciar da concorrência (Grönroos, 2007). Com vista a aprofundar e melhorar o conhecimento sobre o serviço ao cliente e o seu impacto na sua satisfação online surgiu a presente investigação. O objetivo principal da investigação é retratar esse impacto numa empresa portuguesa. Para o efeito foi utilizada a metodologia de Estudo de Caso. Neste estudo é feita uma caracterização da empresa, apresentação e desenvolvimento do conceito de serviço ao cliente e o seu impacto na satisfação do cliente no contexto online. A metodologia usada permitiu aplicar as dimensões da qualidade do serviço em contexto real, analisando o desempenho da Vertbaudet comparativamente aos seus maiores concorrentes: Zippy e Zara Kids. Por fim é descrito o período de estágio que originou o presente relatório, apresentando os objetivos e as atividades desenvolvidas.

To subjectively and objectively compare an accessible interactive electronic library using Moodle with lectures for urology teaching of medical students. Forty consecutive fourth-year medical students and one urology teacher were exposed to two teaching methods (4 weeks each) in the form of problem-based learning: - lectures and - student-centered group discussion based on Moodle (modular object-oriented dynamic learning environment) full time online delivered (24/7) with video surgeries, electronic urology cases and additional basic principles of the disease process. All 40 students completed the study. While 30% were moderately dissatisfied with their current knowledge base, online learning course delivery using Moodle was considered superior to the lectures by 86% of the students. The study found the following observations: (1) the increment in learning grades ranged from 7.0 to 9.7 for students in the online Moodle course compared to 4.0-9.6 to didactic lectures; (2) the self-reported student involvement in the online course was characterized as large by over 60%; (3) the teacher-student interaction was described as very frequent (50%) and moderately frequent (50%); and (4) more inquiries and requisitions by students as well as peer assisting were observed from the students using the Moodle platform. The Moodle platform is feasible and effective, enthusing medical students to learn, improving immersion in the urology clinical rotation and encouraging the spontaneous peer assisted learning. Future studies should expand objective evaluations of knowledge acquisition and retention.

INTRODUCTION: Open access publishing is becoming increasingly popular within the biomedical sciences. SciELO, the Scientific Electronic Library Online, is a digital library covering a selected collection of Brazilian scientific journals many of which provide open access to full-text articles.This library includes a number of dental journals some of which may include reports of clinical trials in English, Portuguese and/or Spanish. Thus, SciELO could play an important role as a source of evidence for dental healthcare interventions especially if it yields a sizeable number of high quality reports. OBJECTIVE: The aim of this study was to identify reports of clinical trials by handsearching of dental journals that are accessible through SciELO, and to assess the overall quality of these reports. MATERIAL AND METHODS: Electronic versions of six Brazilian dental Journals indexed in SciELO were handsearched at www.scielo.br in September 2008. Reports of clinical trials were identified and classified as controlled clinical trials (CCTs - prospective, experimental studies comparing 2 or more healthcare interventions in human beings) or randomized controlled trials (RCTs - a random allocation method is clearly reported), according to Cochrane eligibility criteria. CRITERIA TO ASSESS METHODOLOGICAL QUALITY INCLUDED: method of randomization, concealment of treatment allocation, blinded outcome assessment, handling of withdrawals and losses and whether an intention-to-treat analysis had been carried out. RESULTS: The search retrieved 33 CCTs and 43 RCTs. A majority of the reports provided no description of either the method of randomization (75.3%) or concealment of the allocation sequence (84.2%). Participants and outcome assessors were reported as blinded in only 31.2% of the reports. Withdrawals and losses were only clearly described in 6.5% of the reports and none mentioned an intention-to-treat analysis or any similar procedure. CONCLUSIONS: The results of this study indicate that a substantial number of reports of trials and systematic reviews are available in the dental journals listed in SciELO, and that these could provide valuable evidence for clinical decision making. However, it is clear that the quality of a number of these reports is of some concern and that improvement in the conduct and reporting of these trials could be achieved if authors adhered to internationally accepted guidelines, e.g. the CONSORT statement.

The objective of this study was to compare the impact on knowledge and counseling skills of face-to-face and Internet-based oral health training programs on medical students. Participants consisted of 148 (82 percent) of the 180 invited students attending their fifth academic year at the Faculty of Medicine, University of Sao Paulo, Brasil, in 2007. The interventions took place during a three-month training period in the clinical Center for Health Promotion, which comprised part of a clerkship in Internal Medicine. The students were divided into four groups: 1) Control Group (Control), with basic intervention; 2) Brochure Group (Br), with basic intervention plus complete brochure with oral health themes; 3) Cybertutor Group (Cy), with basic intervention plus access to an Internet-based training program about oral health themes; and 4) Cybertutor + Contact Group (Cy+C), the same as Cy plus brief proactive contact with a tutor. The impact of these interventions on student knowledge was measured with pre- and post assessments, and student skills in asking and counseling about oral health were assessed with an objective structured clinical examination (OSCE). Multivariate logistic regression models were applied to identify the odds ratios of scoring above Control's medians on the final assessment and the OSCE. In the results, Cy+C performed significantly better than Control on both the final assessment (OR 9.4; 95% CI 2.7-32.8) and the OSCE (OR 5.6; 95% CI 1.9-16.3) and outperformed all the other groups. The Cy+C group showed the most significant increase in knowledge and the best skills in asking and counseling about oral health.

We propose and analyze two different Bayesian online algorithms for learning in discrete Hidden Markov Models and compare their performance with the already known Baldi-Chauvin Algorithm. Using the Kullback-Leibler divergence as a measure of generalization we draw learning curves in simplified situations for these algorithms and compare their performances.

Direct borohydride fuel cells are promising high energy density portable generators. However, their development remains limited by the complexity of the anodic reaction: The borohydride oxidation reaction (BOR) kinetics is slow and occurs at high overvoltages, while it may compete with the heterogeneous hydrolysis of BH(4)(-). Nevertheless, one usually admits that gold is rather inactive toward the heterogeneous hydrolysis of BH(4)(-) and presents some activity regarding the BOR, therefore yielding to the complete eight-electron BOR. In the present paper, by coupling online mass spectrometry to electrochemistry, we in situ monitored the H(2) yield during BOR experiments on sputtered gold electrodes. Our results show non-negligible H(2) generation on Au on the whole BOR potential range (0-0.8 V vs reversible hydrogen electrode), thus revealing that gold cannot be considered as a faradaic-efficient BOR electrocatalyst. We further propose a relevant reaction pathway for the BOR on gold that accounts for these findings.

There is little empirical data about the impact of digital inclusion on cognition among older adults. This paper aimed at investigating the effects of a digital inclusion program in the cognitive performance of older individuals who participated in a computer learning workshop named ""Idosos On-Line`` (Elderly Online). Forty-two aged individuals participated in the research study: 22 completed the computer training workshop and 20 constituted the control group. All subjects answered a sociodemographic questionnaire and completed the Addenbrooke`s cognitive examination, revised (ACE-R), which examines five cognitive domains: orientation and attention, memory, verbal fluency, language, and visuo-spatial skills. It was noted that the experimental group`s cognitive performance significantly improved after the program, particularly in the language and memory domains, when compared to the control group. These findings suggest that the acquisition of new knowledge and the use of a new tool, that makes it possible to access the Internet, may bring gains to cognition. (C) 2010 Elsevier Ireland Ltd.

One of the electrical impedance tomography objectives is to estimate the electrical resistivity distribution in a domain based only on electrical potential measurements at its boundary generated by an imposed electrical current distribution into the boundary. One of the methods used in dynamic estimation is the Kalman filter. In biomedical applications, the random walk model is frequently used as evolution model and, under this conditions, poor tracking ability of the extended Kalman filter (EKF) is achieved. An analytically developed evolution model is not feasible at this moment. The paper investigates the identification of the evolution model in parallel to the EKF and updating the evolution model with certain periodicity. The evolution model transition matrix is identified using the history of the estimated resistivity distribution obtained by a sensitivity matrix based algorithm and a Newton-Raphson algorithm. To numerically identify the linear evolution model, the Ibrahim time-domain method is used. The investigation is performed by numerical simulations of a domain with time-varying resistivity and by experimental data collected from the boundary of a human chest during normal breathing. The obtained dynamic resistivity values lie within the expected values for the tissues of a human chest. The EKF results suggest that the tracking ability is significantly improved with this approach.
