Automation of generalized additive neural networks for predictive data mining
No full textFor a new technology to make the step from experimental technology to mainstream technology, tools need to be created to facilitate the use of the developed technology in the envisaged application area. Generalized additive neural networks provide an attractive framework that shows promise in the field of predictive data mining. However, the construction of such networks is very time consuming and subjective, because it depends on the user to interpret partial residual plots and to make changes in the neural network architecture. For this technology to be accepted as a serious modeling option in the field of predictive data mining the construction process needs to be automated and the benefits of using the technique must be clearly illuminated. This article shows how intelligent search may be used to replace subjective human judgment with objective criteria and make generalized additive neural networks an attractive option for the modeler
Sans toit ni loi
No full textTourné au milieu des années 1980 (en 1985 exactement), Sans toit ni loi est apparu comme une vivifiante alternative à ce qui dominait le cinéma français de l’époque et que les commentateurs définissaient sous le label déposé du « look ». C’était l’époque du tout à l’image, du studio contre la rue, du cuit contre le cru. Comme le dit si bien pour elle-même le personnage de Mona à Mme Landier dans le film, Sans toit ni loi n’avait pas le « look ». Il se situait ailleurs, dehors, non pas dans la..
The transmission of blue-tongue and horse-sickness by Culicoides
No full textThe articles have been scanned in colour with a HP Scanjet 5590; 300dpi.
Adobe Acrobat XI Pro was used to OCR the text and also for the merging and conversion to the final presentation PDF-format.An account is given of an investigation into the transmission of blue-tongue
and horse-sickness conducted at Onderstepoort during 1942 and 1943.
Three positive infections with blue-tongue and one with horse-sickness,
following the injection of emulsions of wild-caught Culicoides into susceptible
animals, are recorded.
The successful transmission of blue-tongue by the bites of Culicoides,
which fed on experimentally sheep 10 days previously, is described.
The identity of the diseases in question had been established clinically,
by subinoculations into susceptible animals and by immunity tests with
homologous strains of the particular virus where possible. The author is
quite confident of the correctness of the diagnoses of the disease conditions
produced.
The special light trap used in the investigation for the trapping of
Culicoides and the technique of handling and storing these insects are briefly
described.
It is concluded that certain species of the genus Culicoides are capable
of becoming infected with and transmitting to susceptible animals by bite
the virus of blue-tongue of sheep.
From the evidence advanced it is anticipated that the transmitter or
transmitters of horse-sickness will be found within the genus Culicoides
Endowing self-directed learning in learning environments: interrelated connection between students’ environments and self-directed preparedness
No full textThere has been a major focus on redesigning curricula and with this in mind, self-directed learning (SDL) also has also become a more imperative feature within the curriculum, and more emphasis is placed on the effective implementation of SDL within teaching and learning communities (classrooms). The aim of this theoretical article is to present a framework that is intended to create an awareness of the impact of the environment of students on SDL. This proposed framework has the potential to empower students when applying SDL in their learning and to act as guide or source for educators who want to development the SDL skills of students. The questions that provide the focus for this paper are: why do students struggle to deal with SDL and or to be prepared for employing SDL in their studies, and secondly: Which factors (domains) of a student's existence influences his/her preparedness to be an effective self-directed student and if educators ought to accommodate students differences for the effective development of SDL skills? The author will present a collection of her ideas about how SDL can be conceptualised in an educational environment to cultivate and empower students as self-directed students. In South Africa, we are looking for instructive methods that could support students. If SDL is effectively employed by educators, and students'backgrounds/environments are kept in mind, SDL can be seen as the opening of the doors of learning and should not to become a trap in an ever-revolving gate of disappointment and despair. The potentials of the acceptance of this proposed framework includes (a) effective self-directed learning in underprepared SDL student; (b) increase these students, as well as other students in the same learning classroom, self-regulatory and self-directed learning skills, where students can take accountability for their own learning; and (c) an increase in these students' academic, emotional and/or cultural preparedness which can improve the ability and or preparedness to be a self-directed practitioner for life
Assessing the state of earth system law
No full textThe proposed paper will undertake an analysis of all earth system law-related literature in order to trace the development, and assess the current state, of earth system law. The analysis will be based on an initial ‘database’ – consisting of nearly 300 publications containing the term ‘earth system law’ (ESL) – generated since the author set up a Google Scholar alert in 2020, and supplemented by searches undertaken in academic databases, including Westlaw, Lexis+, and HeinOnline. Duplicate results and publications that are not available in English or are otherwise inaccessible will be excluded from the assessment. The remaining results will be analysed to determine which ESL publications are being cited and the purpose of such citation. It is anticipated that: some publications simply record the fact that a new paradigm critiquing environmental law has been proposed; some publications use the ESL paradigm to support the arguments made therein or as a frame through which to explore a separate issue (such as the Energy Charter Treaty, transnational environmental law, fossil fuel production, non-humans, or plastics, among others); while others are critical of the ESL paradigm; yet others may offer proposals for advancing ESL. Analysing ESL-related literature in this way will contribute to understanding the extent to which, how, where, and by whom, the ESL paradigm is being utilised as well as its perceived weaknesses. Although much has been written on ESL, such a detailed understanding of its value, and limits, is not fully developed. In turn, insights gained through this assessment will be useful to identify future directions for ESL
What do we mean when we say casualisation of farm work is rising?: Evidence from fruit farms in the Western Cape
No full textDu Toit & Ally's (2003) results on the casualisation of farm work in the Western Cape confirmed the worst fears of sociologists: Globalisation and/or labour laws increased casualisation in agriculture. New labour data and a study conducted in 1976 allow one to revisit the casualisation result for the table grape industry of the Hex River Valley. This paper resolves imprecise definitions of regular versus permanent status, and of casual versus seasonal status. It also examines casualisation and job shedding. Results show a decrease in the share of seasonal work and no change in the casual component of seasonal work. The job status of most farm women in the Valley improved as a result of legislative changes implemented since 1994. Outsourcing is present but insignificant at this point. On the whole data for the table grape industry of the Hex River Valley does not support the hypothesis that globalisation and labour market reform caused dramatic increases in casualisation.Farm labour markets, horticulture, Western Cape, Crop Production/Industries, Labor and Human Capital,
