Side Effects of Ambient Noise Immunity Techniques on Outdoor IEEE 802.11 Deployments
2008
A very common conclusion of many experimental studies about IEEE 802.11 outdoor network deployments is that their poor performance results derive from the unfavorable interference and multi-path signals in which the WLAN-cards are required to operate. Goal of this paper is to show that this condition does not always hold, and unexpected and inaccurated PHY layer implementations can be a primary cause of packet losses. With the support of extensive measurement campaigns led in our campus, we provide the performance evidence that IEEE 802.11 outdoor performance impairments are strongly affected by proprietary interference mitigation techniques that adaptively adjust the WLAN-card receiver sen…
Selection of printed curriculum materials in physical education: Recontextualizing pedagogical knowledge
2011
This paper examines how teachers select printed curriculum materials in PE in Spanish secondary schools through Bernstein’s theory of the pedagogic device. The sample recruited were 310 secondary school PE teachers (210 male and 100 female) belonging to the Valencian community in Spain. The mean age of participants was 37.7 (SD 8.7) and the average of PE teaching years was 11.8 (SD 8.87). Teachers responded individually to an interview-administered questionnaire. Results showed teachers were highly involved in choosing the curriculum materials they use, and a slight predominance for teachers to prepare the PE lesson first and then to choose appropriate materials to develop it. Main selecti…
Professional Learning of Teachers in Ethiopia: Challenges and Implications for Reform
2015
Continuous professional development of teachers is of growing interest globally, as it is considered vital to cope effectively with ongoing changes and to improve the quality of education. This qualitative case study explores potential and actual barriers that hinder teachers’ professional development in Ethiopian schools. Data was collected via interviews and focus group discussions from 37 purposively sampled participants. The study reveals three major challenges in teachers’ development: 1) conceptions and conceptual issues related to teaching, professional development and mentoring, 2) management and leadership, and 3) teachers’ work conditions. The need to reconsider educational change…
TEACHER TEAMS AND SCHOOLS BECOME LEADERS TO DISSEMINATE INNOVATIVE PRACTICE
2016
We will introduce a study about teachers taking part in networking for personal development and becoming teacher leaders. In 2011 a multilevel national joint collaboration network of schools with innovative experience was created to foster dissemination of new teaching and learning experiences among teachers. In order to organize learning for teachers, a lesson based collaborative continuous teacher professional learning model was implemented. The research shows that conducting and analyzing lessons has helped participants become more competent professionals and develop skills that are crucial for a good leader. Categories characterizing teacher leaders and lead schools were identified. Fac…
The effect of social geographic factors on the untreated tooth decay among head start children
2017
Background: Disparities among untreated dental caries exist for children from low-income families in the United States. Understanding of the mechanism of the disparities is required to reduce it and social geographic factors are one of the important influences. Although the effect of fluoridated water has been well reported, studies of other sociogeograpic factors, such as the density of available dentists, are still very limited. The objective of this study is to explore the effect of sociogeographic factors on the number of primary teeth with untreated dental caries among children from low-income families who are enrolled in Head Start programs throughout Northeast Ohio of the United Stat…
The effects of three remineralizing agents on regression of white spot lesions in children: A two-week, single-blind, randomized clinical trial.
2016
Background This study investigated the effect of three remineralizing agents on improving white spot lesions (WSLs). Material and Methods This clinical trial included children who had at least one WSL on anterior teeth of upper or lower jaws. The participants were randomly assigned to 4 groups by treatment: 1) a cream containing casein phosphopeptide-amorphous calcium phosphate and fluoride (MI Paste Plus); 2) a cream containing hydroxyapatite and fluoride (Remin Pro); 3) a 2% sodium fluoride gel; and 4) usual home care (control). The treatment was performed for 3 times over 10 days using special trays for retaining remineralizing agents. The area and mineral content of WSLs were measured a…
Dental pain associated with untreated dental caries and sociodemographic factors in 5-year-old children
2020
Background The aim of this study was to assess the prevalence of dental pain and to examine its association with untreated dental caries in 5-year-old children. Material and Methods This was a cross-sectional study of 261 5-year-old children in Northeast Brazil. Parents answered questions about their socioeconomic conditions and their children's toothache. Trained dentists assessed dental caries using the decayed, missing and filled teeth (dmf-t) index. Binary logistic regression models were used to estimate the unadjusted and adjusted odds ratios (ORs) and the confidence intervals (95% CIs) for the association of dental pain with covariates. The significance level was set at five percent. …
Influence of Social Media on Corporate Heritage Tourism Brand
2017
Heritage tourism is an established research canon. However, corporate heritage tourism is an emerging research stream that integrates the heritage tourism canon and corporate brand attributes. This study, utilising a conceptual approach and proposing a conceptual model, explicates the role of social media (marketer and consumer-generated media) in fostering a sense of community among the corporate heritage tourism brand adherents and visit intention among members of the community. In addition, this study incorporates social identity theory to dilate group dynamics and to foster strong feelings and sense of identity among its community. peerReviewed
The influence of belonging to virtual brand communities on consumers' affective commitment, satisfaction and word‐of‐mouth advertising
2011
PurposeThis paper aims to explore some of the effects of belonging to a virtual brand community on consumer behaviour. It also proposes the concept of belonging as a three‐dimensional construct.Design/methodology/approachThe paper proposes that belonging to a virtual community has positive effects on consumer satisfaction, affective commitment and word‐of‐mouth behaviour. After validation of the measurement scales the hypotheses are contrasted through modelling.FindingsThe data show that belonging to a virtual community may enhance consumer satisfaction, affective commitment and word‐of‐mouth advertising towards the brand around which the community is developed. In addition, the paper intro…
Implementación de estrategias y herramientas de coordinación sociosanitaria en un departamento de salud
2018
Resumen: Es objetivo de este artículo mostrar una experiencia de práctica novedosa implementada por la dirección de un departamento de salud. Se expone un modelo organizativo de coordinación sociosanitaria entre los diferentes niveles asistenciales y sectores, estableciendo sinergias de los recursos sociales y sanitarios comunes del Departamento de Salud Clínico-Malvarrosa (Valencia). Tras un año, se han constituido cinco consejos de salud de zona básica en atención primaria y una comisión de coordinación sociosanitaria integrada por tres subcomisiones: 1) de atención asistencial social y sanitaria, 2) de asociacionismo y voluntariado hospitalario, y 3) de acción comunitaria y participación…
