E-LEARNING STRATEGIES IN THE CONTEXT OF KNOWLEDGE SOCIETY
No full textGiven the actual society, called often knowledge society, most organizations are experimenting with some form of computer-assisted instruction, in order to train their employees. This article presents briefly the main characteristics of the knowledge society and of the e-learning systems, and how these two concepts interact and affect each other. Also, there are identified the most important informatics technologies which can be used in the e-learning applications. In order to analyze the actual e-learning systems, some of them are identified and compared based on various criteria.e-learning, Web Based Training, Knowledge Society, informatics technologies
Extreme ultraviolet emission lines of Ni xii in laboratory and solar spectra
No full textA linear force-free field solution is presented in cylindrical coordinates, formulated in terms of trigonometric and Bessel functions. A numerical exploration has revealed that this solution describes magnetic field lines that meander in Cartesian space, as well as field lines that lie on toroidal flux surfaces. These tori are in (or close to) the plane perpendicular to the cylindrical axis. Nested tori, as well as tori with shells that have finite thickness, were found. The parameter space of the solution shows that the tori exist within a bounded range of values
O poder da palavra e implícitos conversacionais no discurso político de Pieter W. Botha
No full textAbstract (English): The current research article tackles word power, taking into account talking inferences adopting Grice´s perspective (1975). Being so, for the working out of this study, a political speech analysis was needed. Thus, Pieter W. Botha´s political speech of 1985 was adopted, at the time he was South Africa´s Prime Minister and President during the Apartheid system. Methodologically, the study embraced a bibliography consulting methodology (c.f. Marconi & Lakatos, 2003, Freixo, 2011), for allowing in a descriptive study to check the analogy and the differences between the elements of a structure for its analysis. To sum up, it might be stated that the speech analysis of the selected author, can be clinched that there is a systematic saying that leads to a gossiping as a discourse strategy. It might mean that a politic man never take responsibility of his sayings, for letting the receiver check the speech deed.

Key-words: Analysis, Discourse, Inference, Conversational Implicatures.O presente artigo reflete sobre o poder da palavra, tendo em conta as implicaturas conversacionais e visa analisar os efeitos pragmáticos e retóricos da linguagem utilizada por Pieter W. Botha no seu discurso de 1985, considerando os implícitos conversacionais, com o intuito de compreender como esses recursos linguísticos contribuíram para a sustentação ideológica do apartheid e para a perpetuação de um regime baseado na exclusão e no silenciamento do outro, bem como identificar os tipos de implícitos conversacionais presentes no discurso no seu discurso. O trabalho adotou a perspectiva de Grice (1975). A escolha desse discurso resulta do facto de que, apesar de o mesmo ter mais de 30 anos ainda é atual, na medida em que as estratégias discursivas usadas na época, ainda hoje fazem ecos nos nos discursos políticos. Por ser de natureza descritiva e interpretativa, o trabalho adotou uma metodologia baseada em consulta bibliográfica, recorrendo as principais obras que abordam sobre o tema. Os dados analisados foram constituidos a partir do discurso de 1985 de Botha. A análise foi feita mediante trechos de falas retirados no referido discurso. a seleção baseou-se no objetivo do estudo. Análise revelou que a linguagem desempenhou um papel central na sustentação ideológica do regime do apartheid. Por meio de implicaturas conversacionais, insinuações, ironia, eufemismos e omissões estratégicas, Botha construiu enunciados que ocultavam a violência institucional, ao mesmo tempo em que legitimavam a repressão e a exclusão racial. A análise permitiu também verificar a violação sistemática das máximas conversacionais, ao recorrer a metáfora, a ironia, a insinuação. Contudo, pode dizer-se a perspectiva de análise adotada permitiu fazer generalizações ao discurso selecionado, denotando que o mesmo é ideológicamente carregad
Failed states, fading dreams and a failing democracy : the critical role of public law academics

The Representation of Gays and Lesbians in South African Cinema 1985–2013
No full textTHE REPRESENTATION OF GAYS AND LESBIANS IN SOUTH AFRICAN CINEMA 1895-2013 Despite South Africa\u27s progressive constitution which prohibits discrimination against gays and lesbians, as well as a strong gay movement, South African cinematic images of gay men and women are limited and still at the margin of the South African film industry. One ends up with less than 20 short films, a few documentaries and less than 10 features with openly gay and lesbian characters in the past 114 years of South African cinema. Under apartheid, gay and lesbian voices in film and television were silenced. In a 20-year study of the representation of gays and lesbians in African, Asian and Latin American cinema (Botha 2003; 2012; Botha & Swinnen 2010), the author has noted that homosexual experience is unique in South Africa, precisely because of South Africa\u27s history of racial division and subsequent resistance.

Die boek Job as bron van intertekste vir ‘Wie weet?' (<i>Die waarheid gelieg</i>, 1984)
No full textThe Book of Job as a source of intertexts for T.T. Cloete’s short story ‘Wie weet?’ (Die waarheid gelieg, 1984)
T.T. Cloete’s account of a woman's physical and spiritual agony in the short story “Wie weet?” ffrom Die waarheid gelieg, 1984), read within the South African/Afrikaans cultural context, presents several indicators that the Book of Job is its intertext, the most explicit pointer being the role of the sufferer’s sister-in-law. Intertextuality in Cloete’s oeuvre often takes the form of a creative reworking or rereading of texts (cf Scholtz, 1984; Botha, 1984; Roos, 1986). Roos comments on the caricatural treatment of theme in Cloete’s “Veg om te verloor” (Cloete, 1984), highlighted by the rereading imposed on the reader of Van Melle’s well-known story "Die joiner”, creating distrust in the implicit author of the Cloete text. The argument in this essay is that the explicit engagement of the intertext, as in "Wie weet?”, also serves as an affirmative complement to the negative incompleteness of the rereading. Thus the desperate questioning of "Wie weet?” becomes an integral part of a reading of Cloete’s oeuvre as a hymn to God’s omnipotence and mercy, epitomized in the poem "Van Horn en my” (Jukstaposisie, 1982)
The near field boundary of dewatering systems – estimating individual yields for wells operating under gravity flow
No full textThe subject of this thesis is the estimation of individual well yields, which is a fundamental part of a multi-well abstraction system design. A literature review of the subject shows that the current best practice for estimating individual well yields has several shortcomings and that further research on the topic is required for individual wells operating under gravity flow. The proposal by Sichardt (1927) for estimating the hydraulic gradient at entry into wells is reviewed and his suggestions are compared to the findings in the field. Pumping test data from eight individual abstraction wells, operating under gravity flow in aquifers having a range of permeability values, are presented. The permeability of the aquifer and the implied hydraulic entry gradient into the well were calculated from the data. The findings also show that Sichardt’s (1927) formula provides reasonable results for permeabilities in the range 1 x 10-5 up to 2.15 x 10-3m/s. For permeability values below 1 x 10-5 m/s Sichardt (1927) a reasonable estimation, but the results need to be used with caution
Numerical simulations of rotating axisymmetric sunspots
No full textA numerical model of axisymmetric convection in the presence of a vertical magnetic flux bundle and rotation about the axis is presented. The model contains a compressible plasma described by the non-linear MHD equations, with density and temperature gradients simulating the upper layer of the Sun's convection zone. The solutions exhibit a central magnetic flux tube in a cylindrical numerical domain, with convection cells forming collar flows around the tube. When the numerical domain is rotated with a constant angular velocity, the plasma forms a Rankine vortex, with the plasma rotating as a rigid body where the magnetic field is strong, as in the flux tube, while experiencing sheared azimuthal flow in the surrounding convection cells, forming a free vortex. As a result, the azimuthal velocity component has its maximum value close to the outer edge of the flux tube. The azimuthal flow inside the magnetic flux tube and the vortex flow is prograde relative to the rotating cylindrical reference frame. A retrograde flow appears at the outer wall. The most significant convection cell outside the flux tube is the location for the maximum value of the azimuthal magnetic field component. The azimuthal flow and magnetic structure are not generated spontaneously, but decay exponentially in the absence of any imposed rotation of the cylindrical domain
Lessons from Mr. Noki : empire, structural violence and the Missio Dei

Reconciliation, forgiveness and violence in Africa : biblical, pastoral and ethical perspectives. Stellenbosch: SUN PReSS, doi:10.18820/9781928480532/06.The original publication is available from AFRICAN SUNMeDIA - www.sun-e-shop.co.zaOn the 16th of August 2012, 34 mineworkers were killed by police in a conflict
between Lonmin’s Marikana2 mine management and their workforce (Botha &
Forster, 2017). The leader of the striking miners, Mgecineni Noki,3 died that day
after advocating for basic increases and a more dignified life. This event has been
likened to the Sharpeville4 of the new South Africa.5 The situation was a boiling pot
consisting of a multinational company seeking best financial return at the expense
of the dignity of mine workers, radicalised unions, militarised police and the misuse
of political power, which resulted in violent and blatant murder as uncovered by
the Farlam Commission6 (Botha & Forster, 2017). What preceded this event is a
clear example of structural violence,7 and the subsequent strike was a reaction to this manifestation of violence. Mgecineni Noki’s life of struggle and his inhumane
death have come to serve as a symbol for all those who have lost their lives in such
conflicts, as well as those who are still held captive by an unjust social, political
and economic system. This chapter does not aim to go into detail about Mr. Noki’s
life, but use his social location as a lens to critique church8 engagement in issues of
violence that undermine the dignity of the most vulnerable peoples.Publisher's versio
