Problem This dissertation presents a literature-based framework for communication in science (with the elements partners, purposes, message, and channel), which it then applies in and amends through an empirical study of how geoscientists use two social computing technologies (SCTs), blogging and Twitter (both general use and tweeting from conferences). How are these technologies used and what value do scientists derive from them? Method The empirical part used a two-pronged qualitative study, using (1) purposive samples of ~400 blog posts and ~1000 tweets and (2) a purposive sample of 8 geoscientist interviews. Blog posts, tweets, and interviews were coded using the framework, adding new codes as needed. The results were aggregated into 8 geoscientist case studies, and general patterns were derived through cross-case analysis. Results A detailed picture of how geoscientists use blogs and twitter emerged, including a number of new functions not served by traditional channels. Some highlights: Geoscientists use SCTs for communication among themselves as well as with the public. Blogs serve persuasion and personal knowledge management; Twitter often amplifies the signal of traditional communications such as journal articles. Blogs include tutorials for peers, reviews of basic science concepts, and book reviews. Twitter includes links to readings, requests for assistance, and discussions of politics and religion. Twitter at conferences provides live coverage of sessions. Conclusions Both blogs and Twitter are routine parts of scientists' communication toolbox, blogs for in-depth, well-prepared essays, Twitter for faster and broader interactions. Both have important roles in supporting community building, mentoring, and learning and teaching. The Framework of Communication in Science was a useful tool in studying these two SCTs in this domain. The results should encourage science administrators to facilitate SCT use of scientists in their organization and information providers to search SCT documents as an important source of information.

Deficits in social communication and interaction have been identified as distinguishing impairments for individuals with an autism spectrum disorder (ASD). As a pivotal skill, the successful development of social communication and interaction in individuals with ASD is a lifelong objective. Point-of-view video modeling has the potential to address these deficits. This type of video involves filming the completion of a targeted skill or behavior from a first-person perspective. By presenting only what a person might see from his or her viewpoint, it has been identified to be more effective in limiting irrelevant stimuli by providing a clear frame of reference to facilitate imitation. The current study investigated the use of point-of-view video modeling in teaching social initiations (e.g., greetings). Using a multiple baseline across participants design, five kindergarten participants were taught social initiations using point-of-view video modeling and video priming. Immediately before and after viewing the entire point-of-view video model, the participants were evaluated on their social initiations with a trained, typically developing peer serving as a communication partner. Specifically, the social initiations involved participants’ abilities to shift their attention toward the peer who entered the classroom, maintain attention toward the peer, and engage in an appropriate social initiation (e.g., hi, hello). Both generalization and maintenance were tested. Overall, the data suggest point-of-view video modeling is an effective intervention for increasing social initiations in young students with ASD. However, retraining was necessary for acquisition of skills in the classroom environment. Generalization in novel environments and with a novel communication partner, and generalization to other social initiation skills was limited. Additionally, maintenance of gained social initiation skills only occurred in the intervention room. Despite the limitations of the study and variable results, there are a number of implications moving forward for both practitioners and future researchers examining point-of-view modeling and its potential impact on the social initiation skills of individuals with ASD.

The following paper is an action research made with a group of 6 teenagers aged 11-13 from the city of Cali. The project was carried out at a non-formal education institution and basically describes the process of a teaching intervention in which the concepts of Critical Pedagogy and Task-Based Learning were the protagonists. The results show first, that students really need to feel motivated in order to accept a critical approach; second, that the role of the teacher in the achievement of the objectives is extremely relevant; it is necessary for them to have a critical perspective before working on this field besides the constant seeking of information in order to innovate in their classes; third, that the TBL (Task Based Learning) and the critical pedagogy are processes that need some time in order to bear fruits; and fourth, that a needs analysis is essential for the quality of the intervention.

Children live at a time when the rapid turnover of information and the ongoing changes in the technological, social, cultural, political and economic spheres make it more difficult for teachers to prepare lessons that enhance students’ interest and motivation. There is so much to be learnt outside of the classroom’s four walls that traditional methods of teaching may not be the most effective way to teach today’s learners. When it comes to classes of Portuguese language, teachers are faced with the challenge of teaching culture, literature, grammar and skills such as reading, writing and speaking in a way that involves students as active participants, that is, in a way that engages while also instructing. It means that several strategies need to be adopted, from games to the use of new technologies or, among others, an interdisciplinary approach with maths, (social) sciences and arts, for instance. In an attempt to motivate gifted and talented children that were attending elementary school in a small town near Viseu, in Portugal, The School of Education of the Polytechnic Institute of Viseu was asked to be part of a project in 2013, in a collaborative partnership that proved successful and that was re-enacted in 2015. It is in light of the above that, in this paper, we aim to: a) describe the support that the School of Education provided to these participants, children who were between six and fourteen, by presenting Portuguese language activities that intended to stimulate creative thinking and artistic production; and b) discuss the results of the project, by analysing the students’ productions across verbal and visual modes (ie. script writing and dubbing an excerpt of an animation film, interviews, news reports, drawings, the creation and recitation of poems…). Future activities are on the table, meaning that the School of Education’s commitment to feeding the students’ creativity has shown promising results. Creativity in Portuguese classes is not a guarantee of success but it certainly is food for thought.

This thesis examines digital technologies policies designed for Australian schools and the ways they are understood and interpreted by students, school staff, teachers, principals and policy writers. This study explores the ways these research participant groups interpret and understand the ‘ethical dimension’ of schools’ digital technologies policies for teaching and learning. In this thesis the ethical dimension is considered to be a dynamic concept which encompasses various elements including; decisions, actions, values, issues, debates, education, discourses, and notions of right and wrong, in relation to ethics and uses of digital technologies in schools. In this study policy is taken to mean not only written texts but discursive processes, policy documents including national declarations, strategic plans and ‘acceptable use’ policies to guide the use of digital technologies in schools. The research is situated in the context of changes that have occurred in Australia and internationally over the last decade that have seen a greater focus on the access to and use of digital technologies in schools. In Australian school education, the attention placed on digital technologies in schools has seen the release of policies at the national, state, territory, education office and school levels, to guide their use. Prominent among these policies has been the Digital Education Revolution policy, launched in 2007 and concluded in 2013. This research aims to answers the question: What does an investigation reveal about understandings of the ethical dimension of digital technologies policies and their implementation in school education? The objective of this research is to examine the ethical dimension of digital technologies policies and to interpret and understand the responses of the research participants to the issues, silences, discourses and language, which characterise this dimension. In doing so, it is intended that the research can allow the participants to have a voice that, may be different to the official discourses located in digital technologies policies. The thesis takes a critical and interpretative approach to policies and examines the role of digital technologies policies as discourse. Interpretative theory is utilised as it provides a conceptual lens from which to interpret different perspectives and the implications of these in the construction of meaning in relation to schools’ digital technologies policies. Critical theory is used in tandem with interpretative theory as it represents a conceptual basis from which to critique and question underlying assumptions and discourses that are associated with the ethical dimension of schools’ digital technologies policies. The research methods used are semi-structured interviews and policy document analysis. Policies from the national, state, territory, education office and school level were analysed and contribute to understanding the way the ethical dimension of digital technologies policies is represented as a discourse. Students, school staff, teachers, principals and policy writers participated in research interviews and their views and perspectives were canvassed in relation to the ethical use of digital technologies and the policies that are designed to regulate their use. The thesis presents an argument that the ethical dimension of schools’ digital technologies policies and use is an under-researched area, and there are gaps in understanding and knowledge in the literature which remain to be addressed. It is envisaged that the thesis can make a meaningful contribution to understand the ways in which schools’ digital technologies policies are understood in school contexts. It is also envisaged that the findings from the research can inform policy development by analysing the voices and views of those in schools. The findings of the policy analysis revealed that there is little attention given to the ethical dimension in digital technologies at the national level. A discourse of compliance and control pervades digital technologies policies from the state, education office and school levels, which reduces ethical considerations to technical, legal and regulatory requirements. The discourse is largely instrumentalist and neglects the educative dimension of digital technologies which has the capacity to engender their ethical use. The findings from the interview conversations revealed that students, school staff and teachers perceive digital technologies policies to be difficult to understand, and not relevant to their situation and needs. They also expressed a desire to have greater consultation and participation in the formation and enactment of digital technologies policies, and they believe they are marginalised from these processes in their schools. Arising from the analysis of the policies and interview conversations, an argument is presented that in the light of the prominent role played by digital technologies and their potential for enhancing all aspects of school education, more research is required to provide a more holistic and richer understanding of the policies that are constructed to control and mediate their use.

Background: There is a high prevalence of gastro-duodenal disease in sub-Saharan Africa. Peptic ulcer disease in dyspeptic patients, 24.5%, was comparable to prevalence of gastro-duodenal disease among symptomatic individuals in developed countries (12 – 25%). Limited data exists regarding its associated risk factors despite accumulating evidence indicating that gastroduodenal disease is common in Ghana. Objectives: This study investigates risk factors associated with gastro-duodenal disease at the Korle-Bu Teaching Hospital, Accra, Ghana. Methods: This study utilized a cross-sectional design to consecutively recruit patients referred with upper gastro-intestinal symptoms for endoscopy. The study questionnaire was administered to study participants. Helicobacter pylori infection was confirmed by rapid-urease examination at endoscopy. Results: Of 242 patients sampled; 64 had duodenal ulcer, 66 gastric ulcer, 27gastric cancer and 64 non-ulcer dyspepsia. Nineteen (19) had duodenal and gastric ulcer while 2 had gastric ulcer and cancer. A third (32.6%) of patients had history of NSAIDuse. H. pylori was associated with gastric ulcer (p=0.033) and duodenal ulcer (p=0.001). There was an increased prevalence of duodenal ulcer in H. pylori-infected patients taking NSAIDs, P=0.003. Conclusion: H. pylori was a major risk factor for peptic ulcer disease. However, NSAID-related gastro-duodenal injury has been shown to be common in H. pylori infected patients. It highlights the need for awareness of the adverse gastro-intestinal effects in a H. pylori endemic area.

Credible spatial information characterizing the structure and site quality of forests is critical to sustainable forest management and planning, especially given the increasing demands and threats to forest products and services. Forest managers and planners are required to evaluate forest conditions over a broad range of scales, contingent on operational or reporting requirements. Traditionally, forest inventory estimates are generated via a design-based approach that involves generalizing sample plot measurements to characterize an unknown population across a larger area of interest. However, field plot measurements are costly and as a consequence spatial coverage is limited. Remote sensing technologies have shown remarkable success in augmenting limited sample plot data to generate stand- and landscape-level spatial predictions of forest inventory attributes. Further enhancement of forest inventory approaches that couple field measurements with cutting edge remotely sensed and geospatial datasets are essential to sustainable forest management. We evaluated a novel Random Forest based k Nearest Neighbors (RF-kNN) imputation approach to couple remote sensing and geospatial data with field inventory collected by different sampling methods to generate forest inventory information across large spatial extents. The forest inventory data collected by the FIA program of US Forest Service was integrated with optical remote sensing and other geospatial datasets to produce biomass distribution maps for a part of the Lake States and species-specific site index maps for the entire Lake State. Targeting small-area application of the state-of-art remote sensing, LiDAR (light detection and ranging) data was integrated with the field data collected by an inexpensive method, called variable plot sampling, in the Ford Forest of Michigan Tech to derive standing volume map in a cost-effective way. The outputs of the RF-kNN imputation were compared with independent validation datasets and extant map products based on different sampling and modeling strategies. The RF-kNN modeling approach was found to be very effective, especially for large-area estimation, and produced results statistically equivalent to the field observations or the estimates derived from secondary data sources. The models are useful to resource managers for operational and strategic purposes.

In order to identify the impact of teaching menstrual health and hygiene with reusable menstrual pads on knowledge retention and school attendance, qualitative and quantitative data was collected from three rural schools in three districts of eastern Uganda: Amuria, Bukedea, and Ngora. Research techniques employed were preliminary and post surveys of 85 young women; average age 16.9 years. Findings include positive and negative results. Participants’ feelings of normalcy and comfort increased and participants had improved understanding of sexual climax and appropriate menstrual management strategies. There was no statistically significant impact of teaching on topics of sexual intercourse or pregnancy. The impact of reusable menstrual pad sanitary technology on school attendance was negative as more young women reported missing up to a full day of school during their menstrual period (χ2 (3, 73) = 7.81, p = 0.05). Study limitations are discussed and future work is suggested.

Research has found that children with autism spectrum disorders (ASD) show significant deficits in receptive language skills (Wiesmer, Lord, & Esler, 2010). One of the primary goals of applied behavior analytic intervention is to improve the communication skills of children with autism by teaching receptive discriminations. Both receptive discriminations and receptive language entail matching spoken words with corresponding objects, symbols (e.g., pictures or words), actions, people, and so on (Green, 2001). In order to develop receptive language skills, children with autism often undergo discrimination training within the context of discrete trial training. This training entails teaching the learner how to respond differentially to different stimuli (Green, 2001). It is through discrimination training that individuals with autism learn and develop language (Lovaas, 2003). The present study compares three procedures for teaching receptive discriminations: (1) simple/conditional (Procedure A), (2) conditional only (Procedure B), and (3) conditional discrimination of two target cards (Procedure C). Six children, ranging in age from 2-years-old to 5-years-old, with an autism diagnosis were taught how to receptively discriminate nine sets of stimuli. Results suggest that the extra training steps included in the simple/conditional and conditional only procedures may not be necessary to teach children with autism how to receptively discriminate. For all participants, Procedure C appeared to be the most efficient and effective procedure for teaching young children with autism receptive discriminations. Response maintenance and generalization probes conducted one-month following the end of training indicate that even though Procedure C resulted in less training sessions overall, no one procedure resulted in better maintenance and generalization than the others. In other words, more training sessions, as evident with the simple/conditional and conditional only procedures, did not facilitate participants’ ability to accurately respond or generalize one-month following training. The present study contributes to the literature on what is the most efficient and effective way to teach receptive discrimination during discrete trial training to children with ASD. These findings are critical as research shows that receptive language skills are predictive of better outcomes and adaptive behaviors in the future. ^

With the exponential growth of the usage of web-based map services, the web GIS application has become more and more popular. Spatial data index, search, analysis, visualization and the resource management of such services are becoming increasingly important to deliver user-desired Quality of Service. First, spatial indexing is typically time-consuming and is not available to end-users. To address this, we introduce TerraFly sksOpen, an open-sourced an Online Indexing and Querying System for Big Geospatial Data. Integrated with the TerraFly Geospatial database [1-9], sksOpen is an efficient indexing and query engine for processing Top-k Spatial Boolean Queries. Further, we provide ergonomic visualization of query results on interactive maps to facilitate the user’s data analysis. Second, due to the highly complex and dynamic nature of GIS systems, it is quite challenging for the end users to quickly understand and analyze the spatial data, and to efficiently share their own data and analysis results with others. Built on the TerraFly Geo spatial database, TerraFly GeoCloud is an extra layer running upon the TerraFly map and can efficiently support many different visualization functions and spatial data analysis models. Furthermore, users can create unique URLs to visualize and share the analysis results. TerraFly GeoCloud also enables the MapQL technology to customize map visualization using SQL-like statements [10]. Third, map systems often serve dynamic web workloads and involve multiple CPU and I/O intensive tiers, which make it challenging to meet the response time targets of map requests while using the resources efficiently. Virtualization facilitates the deployment of web map services and improves their resource utilization through encapsulation and consolidation. Autonomic resource management allows resources to be automatically provisioned to a map service and its internal tiers on demand. v-TerraFly are techniques to predict the demand of map workloads online and optimize resource allocations, considering both response time and data freshness as the QoS target. The proposed v-TerraFly system is prototyped on TerraFly, a production web map service, and evaluated using real TerraFly workloads. The results show that v-TerraFly can accurately predict the workload demands: 18.91% more accurate; and efficiently allocate resources to meet the QoS target: improves the QoS by 26.19% and saves resource usages by 20.83% compared to traditional peak load-based resource allocation.

This article aims to reflect on the impact of Information and Communication Technologies (ICT) in the educational context, focusing on the potential contributions of the use of Digital Educational Resources (RED) in the process of teaching and learning. For this purpose, the results of the use of the RED will be presented:. Digital Classroom - The World's 1st Year Carochinha The study was accomplished in a class of the 1st grade of the 1st CEB, composed of 27 students, aged 6-7 years in Castelo Branco City Schools Group within the Supervised Teaching Practice. The results obtained after the analysis and processing of the data showed that when using this RED students show they have acquired the content covered by the fact that they enhanced levels of greater interest, commitment, motivation, commitment and initiative in the course of activities proposals. But, perhaps because they are students of 1st year of the 1st CEB, do not neglect the presence and monitoring of the teacher and the use of paper-based resources. This means that there should be a complementarity that reconciles the human factor (teacher), with the use of digital media resources and paper support resources (Manual).

This project in teaching innovation and improvement aims to disseminate the case method as one of the most innovative educational instruments inteaching of Law in general, and specifically with regard to Family and Inheritance Law. The methodology used ensures learning through a legal conflict, which must be resolved by the students themselves from different viewpoints as legal agents. This is an activity in teaching innovation, in which students become the protagonists. Participation is voluntary, and the main aim is student motivation. The subject's aim is for students to learn public speaking skills fundamental to the profession while familiarising themselves with judicial practice. Theteacher sets up a legal conflict in order for students to resolve the dispute as legal agents with divergent viewpoints - in other words, as judges, attorneys, lawyers and so on. The project seeks alternatives to traditional teaching methods and is an innovative teaching method aimed at professionally training future lawyers as well as being a model that involves students more in their own learning.

Traditionally, the teaching of human anatomy in health sciences has been based on the use of cadaveric material and bone parts for practical study. The bone materials get deteriorated and hardly mark the points of insertion of muscles. However, the advent of new technologies for 3D printing and creation of 3D anatomical models applied to teaching, has enabled to overcome these problems making teaching more dynamic, realistic and attractive. This paper presents some examples of the construction of three-dimensional models of bone samples, designed using 3D scanners for posterior printing with addition printers or polymer injection printers.

Objectives: to evaluate the cognitive learning of nursing students in neonatal clinical evaluation from a blended course with the use of computer and laboratory simulation; to compare the cognitive learning of students in a control and experimental group testing the laboratory simulation; and to assess the extracurricular blended course offered on the clinical assessment of preterm infants, according to the students. Method: a quasi-experimental study with 14 Portuguese students, containing pretest, midterm test and post-test. The technologies offered in the course were serious game e-Baby, instructional software of semiology and semiotechnique, and laboratory simulation. Data collection tools developed for this study were used for the course evaluation and characterization of the students. Nonparametric statistics were used: Mann-Whitney and Wilcoxon. Results: the use of validated digital technologies and laboratory simulation demonstrated a statistically significant difference (p = 0.001) in the learning of the participants. The course was evaluated as very satisfactory for them. The laboratory simulation alone did not represent a significant difference in the learning. Conclusions: the cognitive learning of participants increased significantly. The use of technology can be partly responsible for the course success, showing it to be an important teaching tool for innovation and motivation of learning in healthcare.
