Lehen Hezkuntzako irakasleen gaitasun digitala hobetzeko proposamena

Lan honen helburua, egungo gizarte eta hezkuntzaren desoreka digitala egiaztatzea eta horri aurre egiteko proposamen bat planteatzea izan da. Hori burutzeko, irakasle talde bati Informazio eta komunikaziorako Tresnen (IKT) inguruko galdera batzuk egin zaizkie, teknologia berriekiko haien jakintza, prestakuntza eta erabilera zeintzuk diren ezagutzeko. Jasotako emaitzak aztertu dira eta irakasle hauen ezjakintasun maila baliabide teknologiko berritzaileekiko altua dela ondorioztatu da, haien gaitasun digitala oso baxua izanda. Hori dela eta, arazo horri irtenbide berritzaile bat bilatu zaio, Lehen Hezkuntzako irakasleen prestakuntzara bideratutako tutorial ezberdinak sortu direlarik, web 2.0-ko baliabide batzuen erabilera zein den azalduz.

Symptoms of imbalance associated with cervical spine pathology

The goals of the present study are: to determine the prevalence of dizziness or imbalance in a population of patients with cervical-spine pathology as compared to that in the general population; to determine correlations between cervical spinal pathology and symptoms of dizziness or imbalance.

Dual-hop amplify-and-forward cooperative relaying in the presence of Tx and Rx in-phase and quadrature-phase imbalance

In this study, dual-hop channel state information-assisted amplify-and-forward (AF) cooperative systems in the presence of in-phase and quadrature-phase (I/Q) imbalance, which refers to the mismatch between components in the I and Q branches, are investigated. First, the authors analyse the performance of the considered AF cooperative protocol without compensation for the I/Q imbalance as the benchmark. Then, a compensation algorithm for the I/Q imbalance is proposed, which makes use of the received signals at the destination, from the source and the relay nodes, together with their conjugations to detect the transmitted signal. Moreover, the authors study the considered AF cooperative system implemented with the opportunistic relay selection and the proposed compensation mechanism for the I/Q imbalance. The performance of the AF cooperative system under study is evaluated in terms of average symbol error probability, which is derived by considering transmission in a Rayleigh fading environment. Numerical results are provided and show that the proposed compensation algorithm can efficiently mitigate the effect of the I/Q imbalance. On the other hand, it is observed that the AF cooperative system with opportunistic relay selection acquires a performance gain beyond that without relay selection.

Balancing the digital democratic deficit? E-government

This article responds to Thomas’s (2004) call for investigation into how the internet and World Wide Web are changing government in Australia. It first discusses e-government principles and policies at the federal level, and then investigates initiatives and events in one of Australia’s most populous municipalities, the City of Casey in Melbourne’s southeast. The objective of this approach is to understand the broader context of e-government policy formulation in Australia, and connect this to the level of local government in order to understand the features and dynamics of existing e-government mechanisms. The evidence generated from this approach reveals an imbalance between service delivery and civic engagement in e-government strategies, with the emphasis on consumer-oriented service delivery far outweighing civic participation and political dialogue. The analysis that follows outlines actual and potential political problems flowing from this imbalance — or ‘digital democratic deficit’ — and offers suggestions on how equilibrium might be restored.

The Coming of Post-reflexive Society: Commodification and Language in Digital Capitalism

Language is a unique aspect of human communication because it can be used to discuss itself in its own terms. For this reason, human societies potentially have superior capacities of co-ordination, reflexive self-correction, and innovation than other animal, physical or cybernetic systems. However, this analysis also reveals that language is interconnected with the economically and technologically mediated social sphere and hence is vulnerable to abstraction, objectification, reification, and therefore ideology – all of which are antithetical to its reflexive function, whilst paradoxically being a fundamental part of it. In particular, in capitalism, language is increasingly commodified within the social domains created and affected by ubiquitous communication technologies. The advent of the so-called ‘knowledge economy’ implicates exchangeable forms of thought (language) as the fundamental commodities of this emerging system. The historical point at which a ‘knowledge economy’ emerges, then, is the critical point at which thought itself becomes a commodified ‘thing’, and language becomes its “objective” means of exchange. However, the processes by which such commodification and objectification occurs obscures the unique social relations within which these language commodities are produced. The latest economic phase of capitalism – the knowledge economy – and the obfuscating trajectory which accompanies it, we argue, is destroying the reflexive capacity of language particularly through the process of commodification. This can be seen in that the language practices that have emerged in conjunction with digital technologies are increasingly non-reflexive and therefore less capable of self-critical, conscious change.
