    Heterotopia in Networked Learning: Beyond the Shadow Side of Participation in Learning Communities

    As it has evolved, networked learning (NL) has come to emphasise the importance of the collaborative learning aspects and possibilities of online learning. The importance assumed for 'collaboration based' forms of participation within NL has almost become ubiquitous and is frequently seen as an unquestionable good aspect - a utopian view of participation which does not acknowledge the 'shadow side' of participation in learning. In the paper we examine some of the darker sides of collaborative participation which in its extreme manifestations can be experienced as normative and, we suggest, a form of tyranny of the dominant and which instead of having a liberating effect, reinforces a form of oppression and control. We argue this is most likely to be the case in the absence of reflexivity and understanding of different ways and approaches to participation. We go on to suggest an alternative and potentially more productive perspective which, after Foucault, is a heterotopian one. A perspective that acknowledges and assumes disruption and which disturbs our customary notion of ourselves. Participation in heterotopian spaces is disturbing and ambiguous, but it offers a space in which to imagine, to desire and act differently

    Since fanning in Alaska first began and especially since dairy farming became the primary agricultural industry, there has existed a need for hardy legumes which would survive Alaska winters and produce satisfactory yields of high quality forage. To meet this need hundreds of legume species and strains have been introduced during the past 40 or more years. Almost all have lacked the necessary hardiness or have not been satisfactory agronomically. The release of Alaskland red clover in the spring of 1953 is the first time a hardy legume has been made available to growers in Alaska.Cooperating with the United States Department of Agriculture, Agricultural Research Administratio

    Can the nuclear symmetry potential at supra-saturation densities be negative?

    In the framework of an Isospin-dependent Boltzmann-Uehling-Uhlenbeck (IBUU) transport model, for the central 197^{197}Au+197^{197}Au reaction at an incident beam energy of 400 MeV/nucleon, effect of nuclear symmetry potential at supra-saturation densities on the pre-equilibrium clusters emission is studied. It is found that for the positive symmetry potential at supra-saturation densities the neutron to proton ratio of lighter clusters with mass number A3A\leq3 ((n/p)A3(n/p)_{A\leq3}) is larger than that of the weighter clusters with mass number A>3A>3 ((n/p)A>3(n/p)_{A>3}), whereas for the negative symmetry potential at supra-saturation densities the (n/p)A3(n/p)_{A\leq3} is \emph{smaller} than that of the (n/p)A>3(n/p)_{A>3}. This may be considered as a probe of the negative symmetry potential at supra-saturation densities.Comment: 5 pages, 3 figures, 1 table, to be publishe

    Effect of matrix parameters on mesoporous matrix based quantum computation

    Full text link
    We present a solid state implementation of quantum computation, which improves previously proposed optically driven schemes. Our proposal is based on vertical arrays of quantum dots embedded in a mesoporous material which can be fabricated with present technology. We study the feasibility of performing quantum computation with different mesoporous matrices. We analyse which matrix materials ensure that each individual stack of quantum dots can be considered isolated from the rest of the ensemble-a key requirement of our scheme. This requirement is satisfied for all matrix materials for feasible structure parameters and GaN/AlN based quantum dots. We also show that one dimensional ensembles substantially improve performances, even of CdSe/CdS based quantum dots

    \u27Deviant\u27 Burials in Archaeology

    The term ‘deviant’ is used to describe burials that deviate from the normative burial rites of a given society, at a given point in time. The problem with applying such a term to the archaeological record rests predominantly in the fact that the term ‘deviant’ has a negative connotation. This negative connotation insinuates that the individual in the burial context may have been viewed by their society in a negative light, however, through analysis of case studies it is shown that many ‘deviant’ burials are not in fact burials of people viewed as deviant, but ‘different’ burials given to people based on their circumstances of death. Thus one can observe that their position or reputation in life has not lead to the differential burial, and we cannot assume that they were viewed as deviant in any way. Another problem with the label of ‘deviant’ is its application to people in a society. Deviancy, if interpreted as deviation from a norm, is completely dependent upon a society’s social norms. Therefore deviancy can be a somewhat arbitrary label, as its definition is dependent on a very specific time and place. Behaviours that may be considered deviant in a modern, western setting may not be considered deviant elsewhere, and vice versa
