What do academic libraries have to do with Open Educational Resources? Theme : Long term sustainability of open education projects first steps to start up

This paper will discuss the possible roles of academic libraries in promoting, supporting, and sustaining institutional Open Educational Resource initiatives. It will note areas in which libraries or librarians have skills and knowledge that intersect with some of the needs of academic staff and students as they use and release OERs. It will also present the results of a brief survey of the views of some OER initiatives on the current and potential role of academic libraries.

Shigella in Brazilian children with acute diarrhoea: prevalence, antimicrobial resistance and virulence genes

Diarrhoeal disease is still considered a major cause of morbidity and mortality among children. Among diarrhoeagenic agents, Shigella should be highlighted due to its prevalence and the severity of the associated disease. Here, we assessed Shigella prevalence, drug susceptibility and virulence factors. Faeces from 157 children with diarrhoea who sought treatment at the Children's Hospital João Paulo II, a reference children´s hospital in Belo Horizonte, state of Minas Gerais, Brazil, were cultured and drug susceptibility of the Shigella isolates was determined by the disk diffusion technique. Shigella virulence markers were identified by polymerase chain reaction. The bacterium was recovered from 10.8% of the children (88.2% Shigella sonnei). The ipaH, iuc, sen and ial genes were detected in strains isolated from all shigellosis patients; set1A was only detected in Shigella flexneri. Additionally, patients were infected by Shigella strains of different ial, sat, sen and set1A genotypes. Compared to previous studies, we observed a marked shift in the distribution of species from S. flexneri to S. sonnei and high rates of trimethoprim/sulfamethoxazole resistance.

School age children with HIV/AIDS: possible discrimination and attitudes against

Survey-based study what purpose was to analyse respondents’ opinions about contacts with HIV/AIDS-affected people. It was performed using a paper-pencil method during visits of respondents at primary care centres and on-line through a link to the questionnaire distributed among patients of primary care physicians. The study involved 302 respondents, 80% of whom were women; the average age was 34.48 years. The majority of respondents did not know anyone with HIV/AIDS (89.6%). About 83.3% claimed that they would not decrease contacts with HIV/AIDS-affected people. According to 64.1% of respondents, children with HIV/AIDS should go to kindergarten/public or non-public school. We selected a group of respondents, who previously were not but now are inclined to limit such contacts. These respondents can be a potential target group for HIV/AIDS educational programmes. Most respondents think that there is insufficient information about the HIV/AIDS in the mass media.

MIBG scintigraphy for the diagnosis and follow-up of children with neuroblastoma.

Neuroblastoma (NBL) is the commonest extra-cranial solid tumor in children and the leading cause of cancer related deaths in childhood between the age of 1 to 4 years. NBL may behave in very different ways, from the less aggressive stage 4S NBL or congenital forms that may resolve without treatment in up to 90% of the children, to the high-risk disseminated stage 4 disease in older children with a cure rate of 35 to 40%. Initial staging is crucial for effective management and radiolabeled metaiodobenzylguanidine (MIBG) with iodine-123 is a powerful tool with a sensitivity around 90% and a specificity close to 100% for the diagnosis of NBL. MIBG scintigraphy is used routinely and is mandatory in most investigational clinical trials both for the initial staging of the disease, the evaluation of the response to treatment, as well as for the detection of recurrence during follow-up. With respect to outcome of children presenting disseminated stage 4 NBL, the role of post-therapeutic [(123)I]MIBG scan has been investigated by several groups but so far there is no consensus whereas a complete or very good partial response as assessed by MIBG may be of prognostic value. NBL needs a multimodality approach at diagnosis and during follow-up and MIBG scintigraphy keeps its pivotal role, in particular with respect to bone marrow involvement and/or cortical bone metastases.

KINDERGARTEN TEACHERS’ ATTITUDES TOWARDS INCLUSIVE EDUCATION OF CHILDREN WITH DISABILITIES IN THE REGULAR CLASSROOM IN WUHAN, CHINA

After the international trends towards inclusive education, Chinese legislations mandate the inclusion of students with disabilities into the regular education classroom. The purpose of this study was to investigate the kindergarten teachers’ attitudes towards inclusive education of children with disabilities in the regular classroom, in Wuhan, China, as well their sense of responsibility to include children with disabilities in regular classroom. Ninety kindergarten teachers from public and private kindergartens in Wuhan participated in this study. Descriptive analysis demonstrated that, in general, kindergarten teachers we studied have negative or contradictory attitudes towards inclusive education of children with disabilities in regular classroom. Statistically non-significant differences were found between teachers’ attitudes towards inclusion and teachers’ demographic variables (age, education degree, teaching experience, experience teaching children with disabilities, time experience with children with disabilities and training in special education). Significant correlation was found between teachers’ attitudes towards inclusive education and their sense of responsibility to include children with disabilities in regular classroom. The results allowed the identification of some crucial aspects necessary to achieve the inclusive education

Assessment of skinfold thickness equations in estimating body composition in children with inflammatory bowel

Introduction: Growth is a central process in paediatrics. Weight and height evaluation are therefore routine exams for every child but in some situation, particularly inflammatory bowel disease (IBD), a wider evaluation of nutritional status needs to be performed. The assessment of body composition is essential in order to maintain acceptable growth using the following techniques: Dual-energy X-ray absorptiometry (DEXA), bio-impedance-analysis (BIA) and anthropometric measurements (skinfold thickness skin), the latter being most easily available and most cost effective. Objectives: To assess the accuracy of skinfold equations in estimating percentage body fat (%BF) in children with inflammatory bowel disease (IBD), compared with assessment of body fat dual energy X-ray absorptiometry (DEXA). Methods: Twenty-one patients (11 females, 10 males; mean age: 14.3 years, range 12 - 16 years) with IBD (Crohn's disease n = 15, ulcerative colitis n = 6)). Estimated%BF was computed using 6 established equations based on the triceps, biceps, subscapular and suprailiac skinfolds (Deurenberg, Weststrate, Slaughter, Durnin & Rahaman, Johnston, Brook) and compared to DEXA. Concordance analysis was performed using Lin's concordance correlation and the Bland-Altman limits of agreement method. Results: Durnin & Rahaman's equation shows a higher Lin's concordance coefficient with a small difference amongst raw values for skinfolds and DEXA compared to the other equations. Correlation coefficient between mean and difference is close to zero with a non-significant Bradley-Blackwood test. Conclusion: Body composition in paediatric IBD patients using the Durnin & Rahaman skinfold-equation adequately reflects values obtained by DEXA.

Importància dels factors de risc del TDH en l'adquisició de la lecto-escriptura

A l’actualitat, molts infants distrets i moguts són etiquetats de TDAH. Aquest trastorn és objecte d’estudi en els últims anys dins l’educació, sobretot en els cicles d’educació infantil i primària. És un fet que preocupa a molts professionals, ja que desenvolupa unes mancances i necessitats educatives especials, que afecten al rendiment acadèmic del nen/a. El propòsit d’aquesta recerca és analitzar la correlació entre els factors de risc de TDAH i les dificultats lingüístiques, concretament amb els problemes de la consciència fonològica. Per observar aquesta qüestió s’ha partit d’una mostra de vint-i-quatre alumnes de segon cicle d’Educació Infantil i se’ls ha passat dos tests; un per avaluar els factors de risc de TDAH i l’altre per valorar el nivell de consciència fonològica. I amb els resultats obtinguts, s’ha dissenyat una intervenció que atent a la diversitat i intenta millorar aquestes dificultats lingüístiques que presenten els infants.

Physical activity in adolescence - with special reference to cardiovascular health

Liikunta ja sydän- ja verisuoniterveys nuorilla Aikuisiällä ilmenevien sydän- ja verisuonisairauksien kehitys alkaa lapsuudessa. Vähäinen liikunta lisää vaaraa sairastua sydän- ja verisuonisairauksiin sekä vaikuttaa haitallisesti näiden sairauksien riskitekijöihin läpi elämän. Tämän tutkimuksen tavoitteena oli tutkia nuorten liikuntaa ja sen yhteyttä sydän- ja verisuoniterveyteen. Sydän- ja verisuoniterveyttä tutkittiin riskitekijöiden sekä valtimon laajentumiskyvyn avulla. Tutkittavat koostuivat nuorista, jotka osallistuivat pitkäaikaisen sepelvaltimotaudin ehkäisytutkimuksen (STRIP) 13-vuotistutkimuskäynnille ja jotka raportoivat vapaa-ajan liikuntatottumuksensa (n=560). Liikunnan lisäksi nuorten pituus, paino, verenpaine ja olkavaltimon laajentumiskyky mitattiin sekä analysoitiin laboratorionäytteitä (otettiin verinäyte) ja selvitettiin ruoankäyttöä. Vähäinen vapaa-ajan liikunta oli yleistä etenkin tytöillä. Vapaa-ajallaan vähän liikkuvat pojat viettivät enemmän aikaa televisio- ja tietokoneruudun ääressä kuin vapaa-ajallaan paljon liikkuvat pojat. Äidin, toisin kuin isän, vapaa-ajan liikunta ja paino olivat yhteydessä lapsen vapaa-ajan liikuntaan. Vähän liikkuvat tytöt olivat olleet jo kahden vuoden iästä saakka useammin ylipainoisia kuin runsaammin liikkuvat ikätoverinsa. Sydän- ja verisuonisairauksien riskitekijöiden kasautuminen oli tavallisempaa vähän kuin paljon liikkuvilla nuorilla. Vähän liikkuvilla pojilla oli lisäksi huonompi olkavaltimon laajentumiskyky kuin paljon liikkuvilla pojilla. Tämä on tärkeä löydös, koska valtimon laajentumiskyky kuvannee sydän- ja verisuoniterveyttä jo ennen rakenteellisten muutosten ilmaantumista. Useat nuoret, etenkin tytöt, liikkuivat vähän vapaa-ajallaan. Vähäisellä vapaa-ajan liikunnalla oli haitallinen yhteys sydän- ja verisuonisairauksien riskitekijöihin sekä valtimon laajentumiskykyyn. Nuorten kannustaminen liikunnalliseen elämäntapaan on erittäin tärkeää sydän- ja verisuoniterveyden edistämiseksi sekä nuoren että kansanterveyden kannalta.

Argument omissions in preschool Catalan and Spanish speaking children with SLI

El presente artículo describe tres estudios sobre la producción del verbo y la estructura argumental en niños con Trastorno Específico del Lenguaje (TEL) usando diferentes metodologías. El primero es un estudio observacional que usa una muestra de habla espontánea. El segundo usa una tarea experimental de denominación de oraciones como resultado de la observación de videos de acciones. El tercero comprende la tarea de denominación de oraciones con imágenes estáticas en eventos con diferente complejidad argumental. Aunque los datos concretos varían en función de la metodología usada, hay una clara evidencia de que los niños de habla catalana y española con TEL presentan especiales dificultades en la producción de verbos con una alta complejidad en relación a la estructura argumental y cometen errores en la especificación de los argumentos obligatorios. Se concluye quetanto limitaciones en el procesamiento como déficits en la representación semántica de los verbos pueden estar implicados en estas dificultades

The Regulation of Skeletal and Cardiac Muscle Blood Flow in Humans. Studies by positron emission tomography with special reference to exercise, adenosine and nitric oxide

Virtually every cell and organ in the human body is dependent on a proper oxygen supply. This is taken care of by the cardiovascular system that supplies tissues with oxygen precisely according to their metabolic needs. Physical exercise is one of the most demanding challenges the human circulatory system can face. During exercise skeletal muscle blood flow can easily increase some 20-fold and its proper distribution to and within muscles is of importance for optimal oxygen delivery. The local regulation of skeletal muscle blood flow during exercise remains little understood, but adenosine and nitric oxide may take part in this process. In addition to acute exercise, long-term vigorous physical conditioning also induces changes in the cardiovasculature, which leads to improved maximal physical performance. The changes are largely central, such as structural and functional changes in the heart. The function and reserve of the heart’s own vasculature can be studied by adenosine infusion, which according to animal studies evokes vasodilation via it’s a_2A receptors. This has, however, never been addressed in humans in vivo and also studies in endurance athletes have shown inconsistent results regarding the effects of sport training on myocardial blood flow. This study was performed on healthy young adults and endurance athletes and local skeletal and cardiac muscle blod flow was measured by positron emission tomography. In the heart, myocardial blood flow reserve and adenosine A_2A receptor density, and in skeletal muscle, oxygen extraction and consumption was also measured. The role of adenosine in the control of skeletal muscle blood flow during exercise, and its vasodilator effects, were addressed by infusing competitive inhibitors and adenosine into the femoral artery. The formation of skeletal muscle nitric oxide was also inhibited by a drug, with and without prostanoid blockade. As a result and conclusion, it can be said that skeletal muscle blood flow heterogeneity decreases with increasing exercise intensity most likely due to increased vascular unit recruitment, but exercise hyperemia is a very complex phenomenon that cannot be mimicked by pharmacological infusions, and no single regulator factor (e.g. adenosine or nitric oxide) accounts for a significant part of exercise-induced muscle hyperemia. However, in the present study it was observed for the first time in humans that nitric oxide is not only important regulator of the basal level of muscle blood flow, but also oxygen consumption, and together with prostanoids affects muscle blood flow and oxygen consumption during exercise. Finally, even vigorous endurance training does not seem to lead to supranormal myocardial blood flow reserve, and also other receptors than A_2A mediate the vasodilator effects of adenosine. In respect to cardiac work, atheletes heart seems to be luxuriously perfused at rest, which may result from reduced oxygen extraction or impaired efficiency due to pronouncedly enhanced myocardial mass developed to excel in strenuous exercise.

Bonding of Composite Resin to Alumina and Zirconia Ceramics with Special Emphasis on Surface Conditioning and Use of Coupling Agents

Dental oxide ceramics have been inspired by their biocompability and mechanical properties which have made durable all-ceramic structures possible. Clinical longevity of the prosthetic structures is dependent on effective bonding with luting cements. As the initial shear bond strength values can be comparable with several materials and procedures, long-term durability is affected by ageing. Aims of the current study were: to measure the shear bond strength of resin composite-to-ceramics and to evaluate the longevity of the bond; to analyze factors affecting the bond, with special emphasis on: the form of silicatization of the ceramic surface; form of silanization; type of resin primer and the effect of the type of the resin composite luting cement; the effect of ageing in water was studied regarding its effect to the endurance of the bond. Ceramic substrates were alumina and yttrium stabilized zirconia. Ceramic conditioning methods included tribochemical silicatization and use of two silane couplings agents. A commercial silane primer was used as a control silane. Various combinations of conditioning methods, primers and resin cements were tested. Bond strengths were measured by shear bond strength method. The longevity of the bond was generally studied by thermocycling the materials in water. Additionally, in one of the studies thermal cycling was compared with long-term water storaging. Results were analysed statistically with ANOVA and Weibull analysis. Tribochemical treatment utilizing air pressure of 150 kPa resulted shear bond strengths of 11.2 MPa to 18.4 MPa and air pressure of 450 kPa 18.2 MPa to 30.5 MPa, respectively. Thermocycling of 8000 cycles or four years water storaging both decreased shear bond strength values to a range of 3.8 MPa to 7.2 MPa whereas initial situation varied from 16.8. Mpa to 23.0 MPa. The silane used in studies had no statistical significance. The use of primers without 10-MDP resulted spontaneous debonding during thermocycling or shear bond strengths below 5 MPa. As conclusion, the results showed superior long-term bonding with primers containing 10-MDP. Silicatization with silanizing showed improved initial shear bond strength values which considerably decreased with ageing in water. Thermal cycling and water storing for up to four years played the major role in reduction of bond strength, which could be due to thermal fatigue of the bonding interface and hydrolytic degradation of the silane coupled interface.

Objective Evaluation of Nasal Dimensions in Children with Acoustic Rhinometry

Aims: This study was carried out to investigate the usefulness of acoustic rhinometry in the evaluation of intranasal dimensions in children. The aim was to define reference values for school children. In addition, the role of the VAS scale in the subjective evaluation of nasal obstruction in children was studied. Materials and methods: Measurements were done with Acoustic Rhinometry A1. The values of special interest were the minimal cross-sectional area (MCA) and the anterior volume of the nose (VOL). The data for reference values included 124 voluntary school children with no permanent nasal symptoms, aged between 7 and 14 years. Data were collected at baseline and after decongestion of the nose; the VAS scale was filled in before measurements. The subjects in the follow-up study (n=74, age between 1 and 12 years) were receiving intranasal spray of insulin or placebo. The nasal symptoms were recorded and acoustic rhinometry was measured at each control visit. Results: In school children, the mean total MCA was 0.752 cm2 (SD 0.165), and the mean total VOL was 4.00 cm3 (SD 0.63) at baseline. After decongestion, a significant increase in the mean TMCA and in the mean TVOL was found. A correlation was found between TMCA and age, and between TVOL and height of a child. There was no difference between boys and girls. A correlation was found between unilateral acoustic values and VAS at baseline, but not after decongestion. No difference wasfound in acoustic values or symptoms between the insulin and placebo group in the follow-up study of two years. Conclusions: Acoustic rhinometry is a suitable objective method to examine intranasal dimensions in children. It is easy to perform and well tolerated. Reference values for children between 7 and 14 years were established.

Factors Affecting Cancer Behavior with Special Reference to Lymphatic Vessels, Macrophages, EGFR, and Pim-1 in Colorectal Cancer

Syövän käyttäytymiseen ja ennusteeseen vaikuttavat monet tekijät, muun muassa muutokset syöpäsoluissa sekä kasvainta ympäröivässä mikroympäristössä. Tutkimuksen tavoitteena oli tutkia uusia prediktiivisiä ja prognostisia ennustetekijöitä syöpäsoluissa (EGFR geenikopiomäärä, EGFR, onkogeeni pim-1) sekä syöpäkasvaimen mikroympäristöön kuuluvissa imuteissä (CLEVER-1, podoplaniini), makrofageissa (CD68, CLEVER-1) ja T lymfosyyteissä (CD3) kolorektaalisyövässä. Lisäksi tutkittiin imuteiden molekulaarisia ominaisuuksia tarkemmin (CD73, LYVE-1, podoplaniini) kuten myös lymfosyyttien ja dendriittisolujen liikennöintiä imuteissä. Tutkimustulokset osoittavat että korkea Pim-1 ekspressiotaso, suuri peritumoraalinen CD68+ makrofagimäärä sekä varhaisen vaiheen taudissa suuri CLEVER-1+ peritumoraalinen makrofagimäärä ovat hyvän ennusteen tekijöitä kolorektaalisyövässä. Metastaattisessa taudissa sen sijaan suuri määrä CLEVER-1+ makrofageja, sekä intra- että peritumoraalisesti, liittyy huonoon tautiennusteeseen. EGFR geenikopiomäärä, EGFR proteiinipitoisuuden ohjaaman hopea in situ hybridisaatiomenetelmän avulla määritettynä, ennusti vastetta anti-EGFR hoidolle metastaattisessa kolorektaalisyövässä tarkemmin kuin nykyisin rutiinisti käytössä oleva KRAS määritys. Lisäksi havaittiin että imutiet ovat monimuotoisia imutiemarkkeri ekspressionsa suhteen sekä normaali- että syöpäkudoksissa. CD73 molekyylin funktio imuteissä poikkesi selvästi molekyylin funktiosta verisuonissa. Yhteenvetona voidaan todeta että kolorektaalisyövän ennusteeseen vaikuttavien tekijöiden merkitys vaihtelee taudin levinneisyysasteen sekä imuteiden että makrofagien sijainnin perusteella. Korkea Pim-1 ilmentyminen on yhteydessä hyvään kolorektaalisyöpäennusteeseen. Lisäksi EGFR geenikopiomäärä osoittautui lupaavaksi uudeksi prediktiiviseksi ennustetekijäksi KRAS villintyypin metastaattista kolorektaalisyöpää sairastavilla potilailla.

Extremfall, stjärnelever och verktygsskramlare : en diskursanalytisk studie av lärares tal om studerande som behöver särskilt stöd

The groups within Finnish vocational upper secondary education and training (VET) are often heterogeneous with respect to the student's need for support in their studies. According to the national core curricula, Special Education Needs (SEN) students should in the first place, get their education in the same group as everyone else. This dissertation aims to clarify and create an understanding about how the ideals and intention of equality in education is constructed in communication among teachers in VET in the Swedish-speaking parts of Finland. Through this understanding it should be possible to highlight a potential which could ultimately contribute to a positive development of a more inclusive education within VET. The epistemological platform of the study is to be found within the post structuralist philosophy of language that is considered as subsumed in a social constructionist thinking. The data has been collected through focus group discussions in groups of 3–6 participants (teachers) in seven schools in Finnish-Swedish VET. The analyses are based on a discursive psychological analysis combined with an analysis based on Michel Foucault's concepts with an emphasis on the subject, government and power. Four discourser where identified in the analysis of teachers' constructions of the educational assignment in relation to SEN students. The most dominant was discussing the educational assignment as a pragmatic project i.e. as a matter of transmission of knowledge. The discourse included both interpretative repertoires where the heterogeneous group was constructed as self-evident and possible to manage as well as a constructed as an impossible project. The educational assignment was also constructed as a holistic project, as part of a democratic project, and as a labor market project. Each discourse contains both including as well as excluding features in relation to SEN students. The development of an inclusive practice can and should therefore include elements from all of them. Three discourses were identified in the analysis concerning teachers' versions of SEN students: students with difficulties and problems; students who do not use or do not have ability and students who are irresponsible and lack the will to study. Within the various discourses and interpretative repertoires were both constructs when teachers described a concern and kindness in relation to the individual SEN student and constructions where teachers mainly expressed fears that other students in the group would be negatively affected by students in need of special support. Results from the third research question conclude the results from the two others, the analysis is done out of a government perspective. In the material use of different government techniques are identified: disciplinary power through direct reprimands; pastoral power by a desire of insight in order to promote the opportunities for consultation and the use of bio-power that primarily focuses on what is best for the population and whose tool racism results in a legitimation of the exclusion of SEN students. The conclusion is that teachers in VET need to pay attention to inclusive and exclusive elements identified in various discourses.

Changing teachers´ practices in regular schools enrolling children with visual impairment

The number of persons with visual impairment in Tanzania is estimated to over 1.6 million. About half a million of these persons are children aged 7-13. Only about 1% of these children are enrolled in schools. The special schools and units are too few and in most cases they are far away from the children’s homes. More and more regular schools are enrolling children with visual impairment, but the schools lack financial resources, tactile teaching materials and trained special education teachers. Children with visual impairment enrolled in regular schools seldom get enough support and often fail in examinations. The general aim of this study was to contribute to increased knowledge and understanding about how teachers can change their teaching practices and thus facilitate the learning of children with visual impairment included in regular classrooms as they participate in an action research project. The project was conducted in a primary school in a poor rural region with a high frequency of blindness and visual impairment. The school was poorly resourced and the average number of pupils per class was 90. The teachers who participated in the collaborative action research project were the 14 teachers who taught blind or visually impaired pupils in grades 4 and 6, in total 6 pupils. The action research project was conducted during a period of 6 months and was carried out in five cycles. The teachers were actively involved in all the project activities; identifying challenges, planning solutions, producing teaching materials, reflecting on outcomes, collaborating and evaluating. Empirical data was collected with questionnaires, interviews, observations and focus group discussions. The findings of the study show that the teachers managed to change their teaching practices through systematic reflection, analysis and collaboration. The teachers produced a variety of tactile teaching materials, which facilitated the learning of the pupils with visual impairment. The pupils learned better and felt more included in the regular classes. The teachers gained new knowledge and skills. They grew professionally and started to collaborate with each other. The study contributes to new knowledge of how collaborative action research can be conducted in the area of special education in a Tanzanian school context. The study has also relevance to the planning of school-based professional development programs and teacher education programs in Tanzania and in other low-income countries. The results also point at strategies which can promote inclusion of children with disabilities in regular schools.
