Full textAbstract:
Distance is a collection of short fiction that explores the spaces between us. Sometimes it's emotional, sometimes it's physical; it lies before us like a cross-country journey, dragging us through emotional terrain fraught with countless dangers and rare rewards. A convict returns to his childhood home. A lonely man documents the unexpected damage of an oil spill in the Gulf of Mexico. A teenager learns that some boots are not made for walking. These stories are the long and short of it. They examine the way we struggle to understand love, lust, disappointment and the kind of detachment that can develop where we least expect it. We all know the distance between two people differs by degree, but in the end, where that space exists, an inescapable question awaits: Should we sever the tie or bridge the gap?ID: 029809051; System requirements: World Wide Web browser and PDF reader.; Mode of access: World Wide Web.; Includes book list (p. 156-159).; Thesis (M.F.A.)--University of Central Florida, 2011.

Honken, Annette Marie. "Mapping distance one neighborhoods within knot distance graphs." Diss., University of Iowa, 2015. https://ir.uiowa.edu/etd/1852.
Full textAbstract:
A knot is an embedding of S1 in three-dimensional space. Generally, it can be thought of as a knotted piece of string with the ends glued together. When we project a knot into the plane, we can create a knot diagram in which we specify which portion of the string lies on top at each place that the string crosses itself. To perform a crossing change on a knot, one can imagine cutting one portion of the string at a crossing, allowing another portion of the string to pass through, and then gluing the cleaved ends back together. We define the distance between two knots, K1 and K2, to be the minimum number of crossing changes one must perform on either K1 or K2 to obtain the other knot.
Circular DNA can become knotted during biological processes such as recombination and replication. We can model knotted DNA with a mathematical knot. Type II topoisomerases are the enzymes tasked with keeping DNA unknotted, and they act on double-stranded circular DNA by breaking the backbone of the DNA, allowing another segment of DNA to pass through, and then re-sealing the break. Thus, performing a crossing change on a knot models the action of this protein. Specifically, studying knots of distance one can help us better understand how the action of a type II topisomerase on double-stranded circular DNA can alter DNA topology.
We create a knot distance graph by letting the set of vertices be rational knots with up to and including thirteen crossings and by placing an edge between two vertices if the two knots corresponding to those vertices are of distance one. A neighborhood of a vertex, v, in a graph is the set of vertices with which v is adjacent via an edge. Using graph theoretical and topological tools, we examine graphs of knot distances and define a mapping between distance one neighborhoods. Additionally, this idea can also be examined and visualized as performing Dehn surgery on the double branched cover of a knot.

Smith, Gary T. "Shouting Distance." UKnowledge, 2017. https://uknowledge.uky.edu/english_etds/54.
Full textAbstract:
Shouting Distance is a collection of ten short stories written by Gary Thomas Smith. Most of the stories take place in Appalachia and rural Kentucky, and the stories set outside of the region still feature characters whose identities are intricately bound to it. The characters' relationships to Appalachia are complex as some embrace the mountains and their culture, while others feel oppressed by that environment. The stories are driven by characters' relationships with family and friends, with their futures and their pasts, or with cultural expectations. The collection explores themes such as poverty, violence, substance abuse, and loss. The natural world is pervasive throughout these stories, and many of them illustrate the effects of human interaction with the environment. While the seeming decline of rural life is at the foreground of this collection, it does not dismiss the beauty of this life. Rather, it suggests that there is promise for the future in spite of loss, hate, and fear.

Diese Dissertation untersuchte individuelle Anpassungsprozesse, die psychologische Distanz in Fernbeziehungen (FB) reflektieren und regulieren. Es wurde postuliert, dass Beziehungsqualität und -stabilität ohne Präsenz des Partners gesichert wird, indem viele kompensatorischen Prozesse auf die wahrgenommene Verfügbarkeit des Partners (Bowlby, 1969/1980), abzielen. Die Ergebnisse zeigen dass die im Vergleich zu zusammenlebenden Paaren erhöhte Bindungsängstlichkeit bei FBs die inkonsistente Verfügbarkeit des Partners reflektiert, und insgesamt für die Beziehungsentwicklung weniger schädlich ist als Vermeidung. Bindung reguliert ferner die psychologische Distanz durch den Einfluss auf adaptive Kommunikationsprozesse. Wenn Aspekte wie sexuelle Zufriedenheit nicht kompensiert werden können, scheinen FBs ihre Einschätzung der Beziehung stark auf Momente des Sehens und die Beziehungsqualität zurückzuführen.This dissertation proposed how relationship quality and stability in long-distance relationships (LDRs) is maintained without physical presence of the partner by basing compensatory processes on perceived partner availability, a core component of attachment theory (Bowlby, 1969/1980). The findings indicate that heightened anxiety reflects the inconsistent partner availability in LDRs, and is less detrimental to relationship development than avoidance. Attachment orientations further regulated the psychological distance between partners by influencing adaptive and protective communicative processes. There was indication that when relational aspects, such as sexual satisfaction, cannot be compensated for, LDRs base their evaluation on face-to-face experiences and general relationship quality indicators. 1

Full textAbstract:
"Get a university degree at home in your spare time!" proclaim the back covers of magazines. Is this distance education? In fact, what is distance education?
There are many definitions of distance education in the literature. They represent distance educators' understanding of the field, and it is partly on the basis of this understanding that professionals develop progams and services. Do learners have the same understanding of distance education? If learners hold different views from educators, the discrepancy may create problems.
Therefore, the writer investigated the conceptions of distance education held by learners who had recently begun distance studies at the university level. She interviewed fifteen learners and analyzed the interviews using phenomenography. This is a qualitative methodology with certain limitations which are discussed in the study. Phenomenogaphy attempts to reveal phenomena as they are perceived by individuals. Consequently, it was the most appropriate methodology to discover learners' conceptions of distance education.
The investigator found four conceptions of distance education; they can be seen as a seed with a sprout. The kernel is distance education perceived as structure and learner actions; this conception is inward-looking. Around the kernel can develop two other conceptions: distance
education as freedom and flexibility and distance education as difficulties counterbalanced by other factors. The fourth conception has two parts: distance education as a door opener (a) to future goals and (b) in everyday life. This is the sprout growing out of the kernel; it is an outward-looking conception.
An analysis of the definitions of distance education in the literature revealed nine themes representing educators' understanding of distance education. There is a close relationship between these themes and two conceptions: "distance education as structure and learner actions" and "distance education as difficulties". On the other hand, important aspects of these and the other conceptions are not represented by the themes. Those missing aspects are all learner-centred.
Although much is written about learners being the focus of distance education, the definitions in the literature indicate a drift from that ideal. It is time for educators to make distance education truly learner-centred.Education, Faculty of

Full textAbstract:
This thesis proposes a modification of Chomsky's (1992) theory of locality to deal with restructuring phenomena which allow an apparent violation of the locality condition on certain local processes. Various restructuring phenomena including long-distance NP movement exemplified by long-distance Object Preposing (Chapter 2) and long-distance head movement exemplified by clitic climbing (Chapter 3) are examined cross linguistically. Long-distance anaphora (Chapter 4) are also examined based on the view the locality on various types of anaphor-antecedent relationships follow from the theory of movement.It is argued that the peculiar behavior of restructuring constructions in terms of locality follows from the lexical properties of restructuring verbs that allows a defective Tense to occur in the complement clause. The following effects result: (i) Case checking within the embedded clause becomes impossible; (ii) the defective Tense triggers incorporation of the infinitive verb into the matrix verb. As a result, the embedded element that requires Case is forced to raise into the matrix clause as a last resort operation, hence motivation long-distance movement.
In order to reconcile long-distance movement with the economy principle which requires chain links to be minimal, this thesis refines Chomsky's (1992) theory of locality. The proposed hypothesis claims that the locality condition on certain operations such as NP movement and head movement follows from the economy principle in such a way that an element can move to the closest position in which its morphological requirement can be satisfied. This notion of the shortest movement is further clarified in that the domain in which the shortest movement requirement is satisfied can be extended if there is an appropriate linked chain formed by head movement. The proposed system not only provides principled account for the phenomena of restructuring, but also has some important implications for the notion of economy of derivation.

Full textAbstract:
Sequences represent a large class of fundamental objects in Computer Science sets, strings, vectors and permutations are considered to be sequences. Distances between sequences measure their similarity, and computations based on distances are ubiquitous: either to compute the distance, or to use distance computation as part of a more complex problem. This thesis takes a very specific approach to solving questions of sequence distance: sequences are embedded into other distance measures, so that distance in the new space approximates the original distance. This allows the solution of a variety of problems including: Fast computation of short sketches in a variety of computing models, which allow sequences to be compared in constant time and space irrespective of the size of the original sequences. Approximate nearest neighbor and clustering problems, significantly faster than the naive exact solutions. Algorithms to find approximate occurrences of pattern sequences in long text sequences in near linear time. Efficient communication schemes to approximate the distance between, and exchange, sequences in close to the optimal amount of communication. Solutions are given for these problems for a variety of distances, including fundamental distances on sets and vectors; distances inspired by biological problems for permutations; and certain text editing distances for strings. Many of these embeddings are computable in a streaming model where the data is too large to store in memory, and instead has to be processed as and when it arrives, piece by piece. The embeddings are also shown to be practical, with a series of large scale experiments which demonstrate that given only a small space, approximate solutions to several similarity and clustering problems can be found that are as good as or better than those found with prior methods.

Limited Sight Distance is a poetry collection, written primarily between August 2012 and March 2014, while I was enrolled in the Master of Fine Arts in Creative Writing program at California State University, Long Beach. In addition to work produced during this time, it also includes poems I completed while a returning undergraduate, as well as others written outside the academic environment; all are intended to reflect both my experience and development as a poet. The subject matter of these narratives includes aging, betrayal, death, family, illness, loss, love, and work, as perceived from varying points of view. I have found that, in life, it is when we are unable to see beyond that which presents itself to us immediately, that our sight distance is limited.

The document which follows represents an exploration of distance and its connection to architecture. This exploration is threefold. On one level it regards distance as an ontological question, researching for precedent work on the subject such as the ancient Greek way of building or, the sociological research of Edward Hall. On another level it undergoes a design process in order to investigate distance vis a vis architectural design in terms of dimensions, architectonic elements and perception. Lastly, it concerns the semantics of distance, particularly from the philosophical point of view of Jean-Paul Sartre.

Full textAbstract:
We investigate mechanisms to improve efficiency for line and point transect surveys of clustered populations by combining the distance methods with adaptive sampling. In adaptive sampling, survey effort is increased when areas of high animal density are located, thereby increasing the number of observations. We begin by building on existing adaptive sampling techniques, to create both point and line transect adaptive estimators, these are then extended to allow the inclusion of covariates in the detection function estimator. However, the methods are limited, as the total effort required cannot be forecast at the start of a survey, and so a new fixed total effort adaptive approach is developed. A key difference in the new method is that it does not require the calculation of the inclusion probabilities typically used by existing adaptive estimators. The fixed effort method is primarily aimed at line transect sampling, but point transect derivations are also provided. We evaluate the new methodology by computer simulation, and report on surveys of harbour porpoise in the Gulf of Maine, in which the approach was compared with conventional line transect sampling. Line transect simulation results for a clustered population showed up to a 6% improvement in the adaptive density variance estimate over the conventional, whilst when there was no clustering the adaptive estimate was 1% less efficient than the conventional. For the harbour porpoise survey, the adaptive density estimate cvs showed improvements of 8% for individual porpoise density and 14% for school density over the conventional estimates. The primary benefit of the fixed effort method is the potential to improve survey coverage, allowing a survey to complete within a fixed time and effort; an important feature if expensive survey resources are involved, such as an aircraft, crew and observers.

A crucial, but little studied, visual function involves estimating distance from the self to an object in the environment (absolute distance perception). This is a fundamental component in the creation of our perception of the 3D world and is likely to be affected by alcohol, and be a factor in drunk driving accidents. To better understand which visual cues observers use to determine distance, participants completed a series of psychophysical judgments under different viewing conditions. By controlling and isolating specific distance cues through a novel viewing apparatus, we were able to investigate which cues are used to accurately judge distance. Alcohol intoxication allows us to selectively investigate the specific visual systems that are and are not involved in contributing to the accuracy of this type of task. Finally, an investigation of the effects of training and feedback on distance estimation tasks in a real 3D environment was also conducted. In summary, this research attempted to uncover not only how the visual system processes spatial information, but also how visual processing changes with alcohol intoxication with implications for understanding alcohol-related visual-spatial dysfunction that may arise in drunk driving. These findings will then be applied to a real world, 3D outdoor environment while investigating the impact of training and feedback on a distance estimation task.The Office of the Graduate School and Interdisciplinary Studies Doctoral Dissertation Fellowship Award

Full textAbstract:
L'absence consiste moins à renoncer à toute présence qu'à introduire dans l'acte d'être une distance qui nie toute plénitude ontologique. A ce titre, la notion de distance pose d'une façon paradoxale la question de l'être : une forme d'existence est encore possible en marge du réel immédiat. Une ontologie de la discrétion révèle cette ambivalence qui empêche et permet d'être à la fois, l'affirmation de l'être se conjugue avec sa négation, comme si nous ne pouvions faire l'expérience de l'existence souveraine : l’être n'est jamais donné dans la pleine positivité d'une présence. De nombreuses figures de l'absence participent de cette ontologie atténuée : la réserve, la timidité, l'ennui, la tristesse, la solitude, la politesse, la pudeur, l'indifférence montrent que tout l'être ne s'engage pas dans les réalités accomplies, soit par défaut, soit par excès d'être. Or, ces formes de l'absence renvoient à un risque ontologique qui peut s'interpréter comme le principe du mal : la logique de division, abondamment exploitée par l'immoralisme, l'emporte sur le principe de solidarité. Encore que c'est davantage l'ambiguïté du retrait de l'être qui est suspecte : indistinctement la distance relie et sépareThe absence is not renounce to any presence but to introduce in the act of being a distance which denies any plenitude. That's why the notion of distance states in a paradoxical way the question of being: a way of existence is still possible on the fuing of the immediate real. An ontology of the discretion reveals this ambiguity which prevents from being and allows it at the same time. We can exist while being distant from things, as if we couldn't experience the absolute existence: the being is not totally in the presence. Numerous examples of absence are dependent on this meaken ontology: reserve, slyness, boudom, sadness, solitude, politeness, modesty, indifference show that the whole being doesn't commit itself into the ended realities. Now, these examples of absence refer to an ontological risk which can be the principle of evict. The logic of division, used by the immorality, prevails our principle of solidarity. However is more the ambiguity of the withdrawer of the being which is suspicions: distance links and separates at the same time

Full textAbstract:
Both organisations and individuals are using more collaborative work, across geographic, disciplinary and organisational boundaries, leading to increased demand for Information and Communication Technologies (ICT) to support a more effective and efficient distributed collaboration. This thesis presents an empirical study exploring various aspects related to collaborative distance in the context of innovation projects. It focuses on the investigation of issues related to distance factors that affect collaboration effectiveness and efficiency. A total of 14 focus group interviews, undertaken with 75 participants in a comparative study of 14 project cases, revealed sufficient evidence on distance factors in the context of mixed (face-to-face and online or virtual) collocation modes. The results confirmed the positive role of collaboration technology for compressing geographical and temporal types of distance; other distance types were also bridged, however, other distance types were created. This empirical study aims to enlarge the academic understanding of distance factors by disambiguating their description and deciphering their role in the collaboration process, and clarifying the reasons for the use and improvement of collaboration technology for overcoming collaborative distances. It also confirms that distance factors raise collaboration barriers, and reveals that they disturb the collaboration mechanics by hindering knowledge workers’ capacity to reach a mutual understanding. Such findings have deep implications for the future enhancement of collaboration technology to fill the current gaps in distributed collaboration, also called e-Collaboration.

Full textAbstract:
This thesis is about distance education as work in campus universities. It seeks to understand how distance education arose and has been sustained in campus universities. The research uncovers that critical to the development and sustainability of distance education are the workers (academic and administrative) who believe and are committed to this form of provision for those who are otherwise unable to study. The literature on distance education rarely addresses the role of the distance education workers. Rather it suggests that distance education is very unlikely to develop, let alone be sustained, if the appropriate infra structure is not in place to support it. More recently a contrasting approach, ignoring policies and organisational structures, suggests that the wide scale adoption of learning technologies will mainstream distance education into conventional university provision. There will be little or no difference between the two methods of course delivery. My professional observation was that neither accounts could explain the vibrant and successful distance education that had grown bottom up within departments in campus universities in the UK. This provision, whilst successful, remained marginal to mainstream university teaching and learning. The research for this thesis took place between 2012 and 2015. It utilises an iterative ethnographically informed interview process and was in two stages. The first stage was concerned with ascertaining what ten internationally well known and successful leaders of distance education provision considered to be the critical factors for successful distance education provision. Called the leader/experts in the research, I had anticipated that they would stress leadership and management - and they did. However what emerged from these first stage conversations was that above all else it was the people who worked in distance education who made it take off and thrive. Thus whilst infra structure and technology were important, they were second order considerations for success. These leader/experts pointed to the team working and shared values of distance education workers and their role, as leaders in distance education, was to provide an enabling environment for distance education workers. The second and substantive stage of the research explores how 27 distance education workers in 6 departments in three UK campus universities, describe their work and why it is important to them. The analysis of the research data suggests that distance education workers, in all research sites, saw themselves as working in non hierarchical teams where all, regardless of grade or role, supported each other, worked cooperatively and learned together. This is described as the distance education community of practice and is seen by the distance education workers as very different to the typical (individualistic and competitive) ways of working in academic departments. In addition the interviewees all stressed their involvement and engagement with their distance education students, and emphasised that in all aspects of their work they were student centred. Interviewees also stressed their belief in the benefit of distance education, in particular emphasising the values of access. These core ideas and dispositions are described in the thesis as the distance education habitus. The distance education community of practice and distance education habitus give the distance education workers a sense of identity separate to their campus colleagues and explains their tireless efforts to 'work around' the systems and processes of the campus university, which are not designed to ensure the flexibility distance education students require for successful study. However all the interviewees, but most particularly in two of the universities (A and C), also reported that these ways of working were being eroded and stifled by changing managerial practices that promoted what were described as more 'efficient' ways of running the university. These managerial practices included technology led systems approaches to the management of all students, and changing requirements demanded of academic staff. The thesis concludes by drawing analogies with other public sector provision and noting the contradictions that whilst higher education policy makers are addressing the need for flexibility the operational management of universities are making this harder to achieve.

Full textAbstract:
An important task in any graphical simulation is the collision detection between the objects in the simulation. It is desirable to have a good general method for collision detection with high performance. This thesis describes an implementation of a collision detection method that uses distance fields to detect collisions. This method is quite robust and able to detect collisions between most possible shapes. It is also capable of computing contact data for collisions. A problem with distance fields is that the performance cost for making a distance field is quite extensive. It is therefore customary to have some way of accelerating the computation of the distance field (usually by only computing select parts of the field). The application implemented in this thesis solves this performance problem by using the parallel framework OpenCL for accelerating the construction of the field.OpenCL enables programmers to execute code on the GPU. The GPU is highly data parallel and a huge increase in performance can be obtained by letting the GPU handle the computations associated with the initiation of the field.

Full textAbstract:
Electrical arcs are usually created with the breakdown of air, requiring an average electric field (AEF) of at least 100 kV/m in long spark gaps. This thesis explores a novel method of creating long electrical arcs using exploding wires (EWs). Arcs up to 60 m long have been produced with AEFs of just 4.5 kV/m. Extensive observations of the EW process are presented, which demonstrate that the arcs, which are a type of ‘restrike', form via the seldom-reported ‘plasma bead' restrike mechanism. Beads of plasma appear to form at sites of wire fragmentation, and can expand and coalesce into a continuous plasma column.
There are strict conditions under which the plasma beads, and hence restrike channels, are produced. A restrike prediction model has been developed to provide a reliable method of producing restrike. The model was derived from the improved understanding of the restrike mechanism, and uses the wire's length and the energy supply voltage and characteristics as inputs. Capability diagrams are then constructed, which allow researchers to easily design experiments that will produce restrike.
Extensive descriptions are provided of the experimental environments that were designed and constructed to facilitate long distance EW experiments. Experiments have been performed inside a high voltage laboratory, in the laboratory's outdoor compound, off the laboratory's earth grid and completely off-site. The off-site location allowed vertical experiments, suspended by a weather balloon, to be performed. This led to a theory on artificially triggered lightning, which is one of many exciting future applications that are suggested. It is also predicted that other research groups will be able to create arcs of several hundred metres long.

Cette thèse est consacrée à la description et à l'étude de la sécurité de divers protocoles destinés à faire de l'authentification d'objets physiques à distance à base de comparaison de vecteurs binaires. L'objectif des protocoles proposés est de pouvoir réaliser une authentification en garantissant d'une part que les informations envoyées et reçues par le lecteur n'ont pas été manipulées par un adversaire extérieur et d'autre part sans révéler l'identité de l'objet testé à un tel adversaire, ou même, modulo certaines hypothèses raisonnables, aux composantes du système. Nous nous sommes fixés de plus comme objectif d'utiliser des méthodes de cryptographie sur courbe elliptique pour pouvoir profiter des bonnes propriétés de ces dernières, notamment une sécurité accrue par rapport à la taille des clefs utilisées. Nous présentons plusieurs protocoles atteignant l'objectif et établissons pour presque tous une preuve théorique de leur sécurité, grâce notamment à une nouvelle caractérisation d'une notion standard de sécurité.

Full textAbstract:
Developments in the interdisciplinary field of quantum information open up previously impossible abilities in the realms of information processing and communication. Quantum entanglement has emerged as one property of quantum systems that acts as a resource for quantum information processing and, in particular, enables teleportation and secure cryptography. Therefore, the creation of entangled resources is of key importance for the application of these technologies. Despite a great deal of research the efficient creation of entanglement over long distances is limited by inevitable noise. This problem can be overcome by creating entanglement between nodes in a network and then performing operations to distribute the entanglement over a long distance. This thesis contributes to the field of entanglement distribution within such quantum networks. Entanglement distribution has been extensively studied for one-dimensional networks resulting in "quantum repeater" protocols. However, little work has been done on higher dimensional networks. In these networks a fundamentally different scaling, called "long distance entanglement distribution", can appear between the resources and the distance separating the systems to be entangled. I reveal protocols that enable long distance entanglement distribution for quantum networks composed of mixed state and give a few limitations to the capabilities of entanglement distribution. To aid in the implementation of all entanglement distribution protocols I finish by introducing a new system, composed of an optical nanofibre coupled to a carbon nanotube, that may enable new forms of photo-detectors and quantum memories.

A good distance metric can improve the accuracy of a nearest neighbour classifier. Xing et al. (2002) proposed distance metric learning to find a linear transformation of the data so that observations of different classes are better separated. For high-dimensional problems where many un-informative variables are present, it is attractive to select a sparse distance metric, both to increase predictive accuracy but also to aid interpretation of the result. In this thesis, we investigate three different types of sparsity assumption for distance metric learning and show that sparse recovery is possible under each type of sparsity assumption with an appropriate choice of L1-type penalty. We show that a lasso penalty promotes learning a transformation matrix having lots of zero entries, a group lasso penalty recovers a transformation matrix having zero rows/columns and a trace norm penalty allows us to learn a low rank transformation matrix. The regularization allows us to consider a large number of covariates and we apply the technique to an expanded set of basis called rule ensemble to allow for a more flexible fit. Finally, we illustrate an application of the metric learning problem via a document retrieval example and discuss how similarity-based information can be applied to learn a classifier.

Full textAbstract:
En droit communautaire et en droit interne français, le contrat à distance est appréhendé comme une technique de commercialisation à distance. Cette conception limitée au droit de la consommation est incomplète. Non seulement le contrat à distance relève également du droit commun des contrats. En effet, la conclusion de contrats à distance ne concerne pas les seules relations entre professionnels et consommateurs. Mais, de plus, il ne s’analyse pas comme une simple modalité de contracter. Etant données les caractéristiques du contrat à distance, il peut être considéré comme un genre contractuel. Il dispose à ce titre d’un critère juridique marquant sa spécificité, la distance contractuelle. En outre, il dispose d’un régime juridique constitué de règles qui lui sont spécifiquement applicables. Plus qu’une technique mise à la disposition des professionnels pour contracter avec les consommateurs, le contrat à distance est une catégorie juridique de contrats à part entièreIn European legislation and French internal rights, the distance contract is understood as a technique of distance marketing. This idea, which is limited to the consumer’s right, is incomplete. Not only the distance contract also concerns the common right of the contracts. Indeed, the concluding of distance contracts is not limited to relations between professionals and consumers. But, moreover, the distance contract is not analysed like a simple method to contract. Being given its characteristics, it can be understood as a kind of contracts. About this, it has a legal criterion marking its specificity, the contractual distance. Besides, it has a legal mode made up of rules which are specifically applicable for it. More than a technique available for professionals to contract with consumers, the distance contract is a legal category of contracts

Critchley missed his father's death by twenty minutes: A nurse took me to see him and then left me alone. The room was unlit and sparsely furnished. In pale winter light, he lay with a single sheet covering his corpse: tiny, withered and ravaged by cancer. I spent no more than five minutes alone with him, initially standing petrified, then sitting, and finally summoning up the courage to touch his cheek and nose and caress his forehead. It felt cool. So, this is what death looks like, I thought. This is what my death will look like.

Full textAbstract:
La vente à distance évolue avec les progrès techniques. Elle se caractérise essentiellement par l'absence de contact direct et simultané entre les contractants, suscitant des adaptations au droit commun des contrats, telles l'obligation d'identification du cocontractant, la détermination du moment et du lieu de formation du contrat et, contribuant à l'émergence d'un régime spécifique d'information et de protection des consommateurs. Avec l'apparition de nouveaux média, tel l'internet, les techniques de communication à distance sont utilisées au maximum de leurs potentialités. Ce dernier présente des caractéristiques inédites telles l'ubiquité, l'interactivité, exacerbant les difficultés traditionnelles de la vente à distance et superposant des difficultés supplémentaires, telle l'absence du support papier. L'internet est un nouvel espace de communication qui transcende les frontières, or cet espace n'est pas celui du droit d'application territoriale. La réflexion à mener est donc internationale. La vente à distance ne connaitra un véritable essor que si le cadre juridique des transactions électroniques est clarifié et adapté afin de renforcer la confiance des consommateurs. Le droit doit rester en phase avec la technologie.

Full textAbstract:
Previous research shows that social biases, such as pro-White racial bias, can influence a person's decisions and behaviors (Correll et al. 2007; Mekawi & Bresin, 2015). Studies also suggest that social biases may influence basic functions like visual perception (Cesario & Navarrete, 2014); however, few studies have examined the relationship between visual perceptions and threat (Cesario, Placks, Hagiwara, Navarrete, & Higgins, 2010; Todd, Thiem, & Neel, 2016). The current research aims to investigate whether implicit pro-White preference can influence basic functions like visual perception. A secondary aim of this study is to examine the role of threat in this relationship. To test, White male and female participants (N= 29) were asked to complete distance estimates to either a Black or White male experimenter. It was hypothesized that participants would judge the distance to the Black confederate as closer compared to those who estimate the distance to a White confederate. The results marginally supported the idea that participants’ distance judgements were influenced by the experimenter’s race, such that the Black experimenter was viewed as closer when compared to the White experimenter. However, results showed that implicit racial attitudes did not influence distance estimations, but explicit bias did. Fully powered follow-up studies will be conducted to further examine these hypotheses and investigate whether a type one error was present.

Full textAbstract:
In Zanzibar, in 1995, opportunities for professional development in environmental education were minimal. Yet the demand for professional development was high, especially because of an emphasis on formal qualifications in the country. Credibility was afforded to forms of professional development, aimed at creating more ‘experts’. Ongoing environmental education practice was not achieving its objectives. Into this setting, which was culturally and socio-politically different from the South African context where it was developed, I introduced the Rhodes University Certificate and Gold Fields Participatory Course in Environmental Education (RU/GF); a non-formal, counter-hegemonic course which encouraged critical reflection on the dominant orientations to environmental education practice – including professional development. I used critical ethnographic and action research methods to explore my praxiological interest, the adaptation of the RU/GF curriculum to the Zanzibar context. During the research process, a decision was made to formally accredit the RU/GF course. This decision did not alter the course orientation or the learning process but opened up possibilities for future curriculum development processes. It allowed the students both a formal qualification necessary for status and promotion, and participation in a learning process that challenged the dominant paradigm on professional development and status from within the socio-political context. The research took on a reflexive orientation to research and environmental education. Through a dialectical development of theory, method and results, several important issues emerged. These deal with the ‘distances’ encountered in attempting to address some of the perceived dichotomies in professional development in environmental education through semi-distance learning: the distances between status and learning; the need for career upgrading and the type of learning considered appropriate for professional development in environmental education; the non-quantifiable aims associated with a reflexive orientation to professional development and formal assessment demands for measurable criteria; the democratisation of open-entry courses and the elitism of restricted access; the focus on individual growth and the attainment of a normative grade; theory and practice; and finally distances between learner, text and language. The research supports similar findings emerging from evaluation of the RU/GF course in South Africa and resonates with, and contributes to, issues concerning professional development in environmental education being considered internationally.

Full textAbstract:
The purpose of the present study was to provide an understanding of the educator-learner relationship in distance education and then to identify and discuss parts of that relationship associated with dropout. Its underlying assumption was that education, at a distance or face-to-face, involves an educator-learner relationship. There were three justifications for this investigation: to illuminate the educator-learner relationship, to contribute to research on dropout in distance education, and to foster integration between practice and scholarship in the field.
The scope of the first research question, what characterizes educator-learner relationships in distance education? necessitated drawing on a broad data base and suggested an interpretive study. The research method chosen was an integrative review of scholarly literature in the field of distance education. In answer to the first research question, the educator-learner relationship in distance education was conceptualized as a wheel with an axle of dialogue, spokes of support, and a rim of independence. The development of this model was the most important result of the present study.
Concern among practitioners over high attrition rates led to the second part of the purpose and the second research question, what characteristics of the educator-learner
relationship in distance education are associated with dropout? In answer to this question, findings from the dropout literature were filtered through the model of the educator-learner relationship in distance education. Tinto’s research into dropout from higher education informed the analysis. Results indicated that perceived deficiencies in dialogue along the spokes of support in the quadrants of learning and instruction have been associated with dropout. This study recognized that the relationship between educator and learner affects student perceptions of intellectual and social integration and so may influence dropout.
Recommendations for research and practice were generated from the model of the educator-learner relationship in distance education. Presence at a distance can be enhanced by a dialogue-centred practice. Suggestions included the tracking of students, professional development for practitioners, and evaluations of distance education practice based on the model of the educator-learner relationship in distance education.Education, Faculty of

Full textAbstract:
In recent years technology has developed significantly and rapidly become an intricate part of people’s daily life in the globalised world. There is a growing recognition that within intimate relationships, technology usage has many functions which can create both negative and positive impacts on intimacy. Yet research on intimacy in online social relationships is still underdeveloped. This paper maps the literature on long-distance relationships and how its participants use information and communication technologies to overcome the physical detachment. The purpose of this study is to examine whether intimacy changes over Erasmus+ exchange studies in long-distance romantic and parental relationships. Data from an online survey of 100 Erasmus+ exchange students residing in Budapest, Hungary were analysed to see whether the quality of their relationship worsens during the exchange period. Based on the data collected it can be concluded that the majority of respondents does not experience critical decay in neither of their relationships and that preparation for distance communication with ICTs is not strongly connected to preventing a decay in intimacy.
