Integration of learning and practice as part of the educational system development in Eritrea. "School Management" - a distance learning program by technical university of Kaiserslautern

The distance learning program "School Management" supports decision makers at the school and ministerial levels in the shaping of formal and informal learning processes at different levels in schools and curricula in Eritrea. This paper examines how the distance learning program is interconnected to educational system development. (DIPF/Orig.)

Constructing strongly-MDS convolutional codes with maximum distance profile

This paper revisits strongly-MDS convolutional codes with maximum distance profile (MDP). These are (non-binary) convolutional codes that have an optimum sequence of column distances and attains the generalized Singleton bound at the earliest possible time frame. These properties make these convolutional codes applicable over the erasure channel, since they are able to correct a large number of erasures per time interval. The existence of these codes have been shown only for some specific cases. This paper shows by construction the existence of convolutional codes that are both strongly-MDS and MDP for all choices of parameters.

L'utilisation de la vidéoconférence comme outil de formation à distance

[...] D'une façon globale, il semble donc exister trois grandes tendances dans le domaine de la formation : 1. une personnalisation de la formation pour l'apprenant ; 2. un rapprochement de la formation vers l'étudiant ; 3. une individualisation de la formation. On entend par personnalisation de la formation le fait que le contenu des cours est de plus en plus adapté aux caractéristiques propres des groupes visés et à leurs besoins. Le rapprochement de la formation vers l'étudiant signifie que plus que jamais, on tente de déplacer la formation vers l'apprenant plutôt que de déplacer celui-ci vers une classe qui ne reflète pas son milieu de travail. Quant à l'individualisation de la formation, cela veut dire que l'étudiant aura, dans un avenir proche, un accès de plus en plus individuel à la formation ; il pourra communiquer avec le formateur lorsqu'il désirera obtenir sa formation. La mise sur pied de centres de formation utilisant la vidéoconférence en salle comme outil de communication par des établissements d'enseignement, tels que l'Université du Tennessee (14 sites de vidéoconférence), le consortium d'éducation de l'Illinois de l'ouest (29 sites), l'école Escambia du comté d'Escambia en Floride (8 sites) et l'Université du Kentucky (7 sites) aux États-Unis, confirment ou nous incitent à croire que ces tendances sont fondées. Ainsi, devant ces nouvelles possibilités et réalités, les entreprises et les établissements d'enseignement doivent réévaluer leurs méthodes de formation à distance. La formation à distance peut-elle bénéficier de ces développements technologiques ? Pourrait-elle utiliser un outil de communication telle que la vidéoconférence pour dispenser des programmes de formation à distance ? Il apparaît donc qu'il faut évaluer la possibilité d'employer la vidéoconférence en salle pour dispenser des programmes de formation à distance.

Étude des variables influençant l’efficacité de la formation à distance

Les nombreux changements technologiques que nous connaissons révolutionnent nos modes de penser, d'agir et de vivre. Aucune connaissance n'est désormais définitive, aucun savoir à son apogée. Il faut constamment se recycler, s'ajuster, se perfectionner : d'où l'expansion actuelle de l'enseignement des adultes à différents niveaux d'enseignement. L'idée que l'éducation soit réservée aux jeunes qui se préparent à la vie, tandis que les adultes doivent se consacrer au travail pour gagner la leur, est en train de se modifier. La période dévolue à l'éducation de type classique déborde sur la vie adulte à mesure que les études scolaires se prolongent et que le désir de découvrir, d'apprendre, se développe. L'éducation permanente, à laquelle l'adulte consacre une partie de son temps, devient une pratique de plus en plus courante. En effet, depuis la réforme amorcée avec le rapport Parent, le système d'éducation québécois a connu une augmentation continue de sa population adulte. De nos jours encore, on ressent cette demande de formation de la part des adultes et il y a tout lieu de croire que cette tendance se poursuivra. (Conseil supérieur de l'éducation, 1988). […]

The Effect of Psychological Distance on Willingness to Engage in Ideologically Based Violence

Research on the cognitive and decision-making processes of individuals who choose to engage in ideologically based violence is vital. Our research examines how abstract and concrete construal mindsets affect likelihood to engage in ideologically based violence. Construal Level Theory (CLT) states that an abstract mindset (high-level construal), as opposed to a concrete mindset (low-level construal), is associated with a greater likelihood of engaging in goal-oriented, value-motivated behaviors. Assuming that ideologically based violence is goal-oriented, we hypothesized that high-level construal should result in an increased likelihood of engaging in ideologically based violence. In the pilot study we developed and tested 24 vignettes covering controversial topics and assessed them on features such as relatability, emotional impact, and capacity to elicit a violent reaction. The ten most impactful vignettes were selected for use in the primary investigations. The two primary investigations examined the effect of high- and low-level construal manipulations on self-reported likelihood of engaging in ideologically based violence. Self-reported willingness was measured through an ideological violence assessment. Data trends implied that participants were engaged in the study, as they reported a higher willingness to engage in ideologically based violence when they had a higher passion for the vignette's social issue topic. Our results did not indicate a significant relationship between construal manipulations and level of passion for a topic.

Long distance coupling of a quantum mechanical oscillator to the internal states of an atomic ensemble

We propose and investigate a hybrid optomechanical system consisting of a micro-mechanical oscillator coupled to the internal states of a distant ensemble of atoms. The interaction between the systems is mediated by a light field which allows the coupling of the two systems in a modular way over long distances. Coupling to internal degrees of freedom of atoms opens up the possibility to employ high-frequency mechanical resonators in the MHz to GHz regime, such as optomechanical crystal structures, and to benefit from the rich toolbox of quantum control over internal atomic states. Previous schemes involving atomic motional states are rather limited in both of these aspects. We derive a full quantum model for the effective coupling including the main sources of decoherence. As an application we show that sympathetic ground-state cooling and strong coupling between the two systems is possible.

Supporting collocated and at-a-distance experiences with TV and VR displays

Televisions (TVs) and VR Head-Mounted Displays (VR HMDs) are used in shared and social spaces in the home. This thesis posits that these displays do not sufficiently reflect the collocated, social contexts in which they reside, nor do they sufficiently support shared experiences at-a-distance. This thesis explores how the role of TVs and VR HMDs can go beyond presenting a single entertainment experience, instead supporting social and shared use in both collocated and at-a-distance contexts. For collocated TV, this thesis demonstrates that the TV can be augmented to facilitate multi-user interaction, support shared and independent activities and multi-user use through multi-view display technology, and provide awareness of the multi-screen activity of those in the room, allowing the TV to reflect the social context in which it resides. For at-a-distance TV, existing smart TVs are shown to be capable of supporting synchronous at-a-distance activity, broadening the scope of media consumption beyond the four walls of the home. For VR HMDs, collocated proximate persons can be seamlessly brought into mixed reality VR experiences based on engagement, improving VR HMD usability. Applied to at-a-distance interactions, these shared mixed reality VR experiences can enable more immersive social experiences that approximate viewing together as if in person, compared to at-a-distance TV. Through an examination of TVs and VR HMDs, this thesis demonstrates that consumer display technology can better support users to interact, and share experiences and activities, with those they are close to.

Head repositioning accuracy in patients with neck pain and asymptomatic subjects: concurrent validity, influence of motion speed, motion direction and target distance

Background: Cervicocephalic kinesthetic deficiencies have been demonstrated in patients with chronic neck pain (NP). On the other hand, authors emphasized the use of different motion speeds for assessing functional impairment of the cervical spine. Purpose: The objectives of this study were (1) to investigate the head repositioning accuracy in NP patients and control subjects and (2) to assess the influence of target distance, motion speed, motion direction and pain. Materials and methods: Seventy-one subjects (36 healthy subjects and 35 NP patients; age 30–55 years) performed the head repositioning test (HRT) at two different speeds for horizontal and vertical movements and at two different distances. For each condition, six consecutive trials were sampled. Results: The study showed the validity and reproducibility of the HRT, confirming a dysfunctional threshold of 4.5°. Normative values of head repositioning error up to 3.6° and 7.1° were identified for healthy and NP subjects, respectively. A distance of 180 cm from the target and a natural motion speed increased HRT accuracy. Repositioning after extension movement showed a significantly larger error in both groups. Intensity, duration of pain as well as pain level did not significantly alter head repositioning error. Conclusions: The assessment of proprioceptive performance in healthy and NP subjects allowed the validation of the HRT. The HRT is a simple, not expensive and fast test, easily implementable in daily practice to assess and monitor treatment and evolution of proprioceptive cervical deficits.
