Processes for Developing Scaffolding in a Computer Mediated Learning Environment.

When in the "zone of proximal development" for a particular skill or piece of information, a learner is ready to learn but lacks certain prerequisites. Scaffolding is an interactive process inwhich a teacher or facilitator assists such a learner to build a "structure" to contain and frame the new information. Scaffolding can be provided by teachers, peers, or computers, and may include the use of tutoring, performance systems, and reciprocal teaching. Online scaffolding practices include scaffolding embedded in the information, such as visual cuing, separate web pages of directions on what to notice or what process to employ, tutorials that are interactive or downloadable, help pages, additional explanatory links, or communication forms to contact the instructor or peers. In computer-mediated learning, scaffolding is more important than in traditional education because learning is typically collaborative, and all participants will provide scaffolding to other participants at different times during the learning process. Therefore, participants must be exposed to the idea of scaffolding and know when it is appropriate in the dialogic process. Pointers on appropriate use of scaffolding are given. The teacher may have to provide prerequisite skills to some students. A computer environment makes the provision of these easier because there is much prepackaged material on the Internet, including visuals, illustrations, and simulations. Students can create materials to help less sophisticated students, and post these on the class web page, thus creating a learning archive. The four stages of facilitated learning, from a constructivist view, are described, as is coaching in collaborative computer-mediated learning. The measure of a well functioning group is the decreasing need for external scaffolding from the teacher, as the members scaffold each other. Contains web sites for online
The intake of acrylamide, nitrate and ochratoxin A in people aged 7 to 69 living in the Netherlands

De voeding van kinderen (7-15 jaar) en (jong) volwassenen (16-69 jaar) in Nederland is veilig wat betreft de inname van nitraat, dat vooral in groenten zit. De hoeveelheid acrylamide waaraan beide leeftijdsgroepen worden blootgesteld via de voeding zou mogelijk schadelijk kunnen zijn voor de gezondheid. Acrylamide zit in gebakken en gefrituurde producten. Voor ochratoxine A, dat wordt veroorzaakt door schimmels, kan niet worden beoordeeld of de voeding veilig is. Meer onderzoek is nodig om de innameberekening te verfijnen. Dit blijkt uit een studie van het RIVM waarin is berekend hoeveel de Nederlandse bevolking van de drie genoemde stoffen binnenkrijgt via de voeding. Voor alle drie de stoffen, maar vooral voor nitraat en ochratoxine A, zijn concentratiegegevens noodzakelijk die een goede afspiegeling zijn voor de gehalten aanwezig in voedselproducten. Voor acrylamide, een mogelijk kankerverwekkende stof, is aangetoond dat het schadelijk is in dieren, maar dit is (nog) niet overtuigend aangetoond in de mens. Meer kennis is nodig over de werking van deze stof bij de mens om te kunnen vaststellen of de berekende inname inderdaad onveilig is. Om de inname via de voeding te berekenen zijn voedselconsumptiegegevens van de Voedselconsumptiepeiling (VCP) gecombineerd met beschikbare concentratiegegevens van de stoffen in producten. Vervolgens is de berekende inname vergeleken met gezondheidslimieten die voor de stoffen gelden om per stof mogelijke gezondheidsrisico's te bepalen.
Combinaison cohérente de diodes laser de puissance

La capacite des sources laser a concentrer une quantite d’energie enorme interesse beaucoup le secteur industriel pour l’usinage et la structuration de la matiere. Il faut pour cela rassembler une forte puissance optique sur une surface infime: on parle alors de luminance. La combinaison coherente permet de repondre a la problematique de l’augmentation de la luminance d’un systeme laser. Dans le cadre du projet europeen BRIDLE, ces travaux sont focalises sur la combinaison coherente de lasers a semi-conducteur. Ce type de combinaison necessite un accord de phase stable entre les differents emetteurs. Plusieurs techniques permettent cette mise en phase; nous etudions en particulier les techniques d’amplification en parallele ainsi que l’utilisation d’une cavite externe commune. L’originalite se situe dans le developpement d’une architecture nouvelle, pensee pour optimiser l’extraction de puissance. La technique consiste a utiliser une cavite etendue commune aux emetteurs a combiner pour leur mise en phase, placee sur leur face arriere. Tout en fournissant un fort retour optique arriere necessaire a la mise en phase, l’extraction de puissance est maximisee sur la face avant ou les faisceaux sont par la suite combines extracavite. Ce document demontre la bonne adequation de cette architecture avec les meilleures diodes laser en termes de luminance : les emetteurs a section evasee. L’etude est etendue a une barrette de diodes par l’utilisation d’elements diffractifs optique permettant la separation et la combinaison des faisceaux.
Robust online visual tracking

Visual tracking plays a key role in many computer vision systems. In this thesis, we study online visual object tracking and try to tackle challenges that present in practical tracking scenarios. Motivated by different challenges, several robust online visual trackers have been developed by taking advantage of advanced techniques from machine learning and computer vision. In particular, we propose a robust distracter-resistant tracking approach by learning a discriminative metric to handle distracter problem. The proposed metric is elaborately designed for the tracking problem by forming a margin objective function which systematically includes distance margin maximization, reconstruction error constraint, and similarity propagation techniques. The distance metric obtained helps to preserve the most discriminative information to separate the target from distracters while ensuring the stability of the optimal metric. To handle background clutter problem and achieve better tracking performance, we develop a tracker using an approximate Least Absolute Deviation (LAD)-based multi-task multi-view sparse learning method to enjoy robustness of LAD and take advantage of multiple types of visual features. The proposed method is integrated in a particle filter framework where learning the sparse representation for each view of a single particle is regarded as an individual task. The underlying relationship between tasks across different views and different particles is jointly exploited in a unified robust multi-task formulation based on LAD. In addition, to capture the frequently emerging outlier tasks, we decompose the representation matrix to two collaborative components which enable a more robust and accurate approximation. In addition, a hierarchical appearance representation model is proposed for non-rigid object tracking, based on a graphical model that exploits shared information across multiple quantization levels. The tracker aims to find the most possible position of the target by jointly classifying the pixels and superpixels and obtaining the best configuration across all levels. The motion of the bounding box is taken into consideration, while Online Random Forests are used to provide pixeland superpixel-level quantizations and progressively updated on-the-fly. Finally, inspired by the well-known Atkinson-Shiffrin Memory Model, we propose MUlti-Store Tracker, a dual-component approach consisting of shortand long-term memory stores to process target appearance memories. A powerful and efficient Integrated Correlation Filter is employed in the short-term store for short-term tracking. The integrated long-term component, which is based on keypoint matchingtracking and RANSAC estimation, can interact with the long-term memory and provide additional information for output control.
Clinical Study of Biliary Ascariasis in Adults: A Hospital Based Study from North Eastern India

Aims and Objectives: to study the clinical presentations and various options for the management of biliary ascariasis. Materials and Methods: This is a retrospective Hospital Based Study carried out in a Tertiary care hospital. A total of 58 patients (31 females and 27 males) were studied over a period of 4 years. All cases of suspected biliary disease were subjected to a thorough history taking, clinical examination and investigations. Results: Biliary ascariasis was more common in female. The mean age of the patients was 35.52 ± 16.01 years. Ultrasonography of abdomen was the diagnostic tool of choice with 100% accuracy. 38 (65.51%) patients recovered with conservative treatment and antihelminthics. In 8 (13.79%) patients, the worms were extracted with upper G.I Endoscopy using a snare. In the rest 12 (20.68%) patients the worms were removed with ERCP using a dormia basket. Conclusion: Ultrasonography is an excellent diagnostic tool. Most of the patients responded to conservative treatment. Early therapeutic ERCP is advisable in patients not responding to conservative treatment.
Comparing teacher’s roles of F2f learning and online learning in a blended English course

Abstract Blended learning has become a popular instruction mode at all levels of education and across different subject areas in recent years. Researchers believe that paradigm shift exists in different domains of blended learning ranging from pedagogy to teacher roles. The present research, thus, used A 27-item and five-likert questionnaire (the STRI) to study how 153 university students perceived the roles of their teachers in both f2f learning and online learning of a blended English course. Statistical analyses revealed two main results: first, all the three sub-roles of teachers in f2f learning had significantly higher means than those in online learning; then in f2f learning, cognitive role had the highest means whereas in online learning, managerial role had the highest means. The findings indicate that, in students’ eyes, teachers had greater impact in f2f learning than in online learning. Furthermore, cognitive role of teachers was perceived to be the most impactful in f2f learning whereas managerial role of teachers was regarded as the most notable in online learning. Further comparison of particular items of the questionnaire revealed more specific differences of teacher roles between the two learning modes.
Audiences for the contemporary arts: Exploring varieties of participation across art forms in Birmingham, UK

This article provides an overview of the key findings of the research project, Understanding Audiences for the Contemporary Arts, a collaboration between the Sheffield Performer and Audience Research Centre (SPARC) and Birmingham Contemporary Music Group (BCMG). The project investigated the experiences of audiences for ‘contemporary’ work across art forms (craft, dance, music, theatre and visual art), and helped develop a collaborative network of contemporary arts organisations in Birmingham. This article provides an account of the distinctive research design employed during the eight months of collaboration in Birmingham and a summary of the project’s six main findings. The paper indicates the implications these findings have for organisations presenting contemporary work and how they might widen and deepen relationships with audiences. It concludes by suggesting the need to move beyond the prevailing vocabularies and conceptualizations of audience ‘access’ and ‘barriers’, and for researchers and cultural organisations to instead address the varieties of participation and the possibilities of ‘cultural citizenship’.
Does activity held on World Asthma Day have an impact on the asthma knowledge and awareness of family physicians?

OBJECTIVE: Annually, certain activities are performed on World Asthma Day (WAD) for the awareness of both patients and physicians about asthma. The study aimed to observe the effects of asthma education on the skills and knowledge of family physicians on WAD, which basically includes updated information of the international asthma guideline. MATERIALS AND METHODS: Our quasi-experimental study was started on May 3, 2016, WAD. Education was provided by the Global Initiative for Asthma, 2016. A questionnaire including 25 questions was applied for family physicians before and 6 months after the education. RESULTS: In the investigation of 32 family physicians, 62.5% were women, with 32.6 ± 26.0 months in family physician practice. 59.4% of the family physicians had received education about asthma in their postgraduate period. Twenty-five percent of the participants were using asthma guidelines in their daily practice. In pre- and posteducation, the percentage of accuracy in the tests was 58.4%–77.6% among specialists and 62.3%–75.9% among trainees of family physicians. The percentage levels of accuracy developed in the questions of focusing asthma treatment and correct inhaler medication use after the education program were 62.5%–93.8% (P = 0.002) and 56.2%–90.6% (P = 0.007), respectively. CONCLUSIONS: Our study revealed that family physicians did not have a tendency to use guidelines for asthma diagnosis and treatment. With the aid of the education program, their attitude changed positively. We believe that family asthma physicians should also be trained in “WAD” activities.
Applying the Health Belief Model to assess prevention services among young adults

ABSTRACT The Health Belief Model (HBM) is one of the many models in health education that can be used as the basis for health promotion programs. The Patient Protection and Affordable Care Act promoted the benefits of preventive care while reducing barriers for young adults to access the health insurance and preventive measures. The purpose of this analysis was to assess the perceived susceptibility, perceived seriousness of health conditions and access to preventive services among young adults. Data were collected from 821 young adults in the northeast region of the United States. Results indicated that there were significant differences based on gender, health status and age on the perceived susceptibility or perceived seriousness of eight major health conditions. In addition, there were significant differences between males and females in regards to the use of prevention services based on their perceptions of susceptibility and seriousness. Results of this study indicate that the HBM constructs of perceived susceptibility and perceived seriousness might play a significant role for young adults to use health preventive services. Future health education and promotion efforts to increase use of preventive services should focus on perceptions of susceptibility and seriousness in young adults.

Delineation of Cocoa Agroforests Using Multiseason Sentinel-1 SAR Images: A Low Grey Level Range Reduces Uncertainties in GLCM Texture-Based Mapping

Delineating the cropping area of cocoa agroforests is a major challenge in quantifying the contribution of land use expansion to tropical deforestation. Discriminating cocoa agroforests from tropical transition forests using multispectral optical images is difficult due to the similarity of the spectral characteristics of their canopies. Moreover, the frequent cloud cover in the tropics greatly impedes optical sensors. This study evaluated the potential of multiseason Sentinel-1 C-band synthetic aperture radar (SAR) imagery to discriminate cocoa agroforests from transition forests in a heterogeneous landscape in central Cameroon. We used an ensemble classifier, Random Forest (RF), to average the SAR image texture features of a grey level co-occurrence matrix (GLCM) across seasons. We then compared the classification performance with results from RapidEye optical data. Moreover, we assessed the performance of GLCM texture feature extraction at four different grey levels of quantization: 32 bits, 8 bits, 6 bits, and 4 bits. The classification’s overall accuracy (OA) from texture-based maps outperformed that from an optical image. The highest OA (88.8%) was recorded at the 6 bits grey level. This quantization level, in comparison to the initial 32 bits in the SAR images, reduced the class prediction error by 2.9%. The texture-based classification achieved an acceptable accuracy and revealed that cocoa agroforests have considerably fragmented the remnant transition forest patches. The Shannon entropy (H) or uncertainty provided a reliable validation of the class predictions and enabled inferences about discriminating inherently heterogeneous vegetation categories.
Compressive spectrum sensing using chaotic matrices for cognitive radio networks

Compressive sensing is an emerging technique in cognitive radio systems, through which sub‐Nyquist sampling rates can be achieved without loss of significant information. In collaborative spectrum sensing networks with multiple secondary users, the problem is to find a reliable and fast sensing method and to secure communication between members of the same network. The method proposed in this paper provides both quick and reliable detection through compressive sensing and security through the use of deterministic chaotic sensing matrices. Deterministic matrices have an advantage over random ones since they are easier to generate and store. Moreover, it is much easier to verify whether a deterministic matrix satisfies the conditions for compressive sensing compared with random matrices, which is what makes them an interesting area of research in compressive sensing. Also, it would be a great advantage if the sensing matrices also provide inherent security, which is the motivation for using chaotic matrices in this paper, since any slight changes in the chaotic parameters result in highly uncorrelated chaotic sequences, hence entirely different sensing matrices. This makes it impossible to reconstruct the signal without proper knowledge of the parameters used to generate the sensing matrix. They can also be easily regenerated by knowing the correct initial values and parameters. Additionally, new modifications are proposed to the existing structures of chaotic matrices. The performance of chaotic sensing matrices for both existing and modified structures is compared with that of random sensing matrices.

Factors predicting success or failure in patients with acute urinary retention who present for trial without catheter

Acute urinary retention (AUR) is a common urological presentation with 1 in 10 men in the eighth decade of life experiencing an episode within 5 years (1) . Patients are often treated initially by urethral catheterisation followed by trial removal of catheter after 3-7 days. The aim of this study was to identify risk factors which may predict success or failure in patients with acute urinary retention who present for trial without catheter (TOV).
