A critical retrospection regarding the legality of abortion in South Africa
Abortion touches at the heart of the commencement of life, and therefore has to be approached accordingly. In this article, the South African jurisprudential debate on the legality of abortion, including the judgment in Christian Lawyers Association of SA v Minister of Health and the Choice on Termination of Pregnancy Act, is critically investigated. In conclusion, a proposed point of departure is postulated, with the aim of shedding more light on foetal status. In this regard, it is argued that, as part of the primary enquiry, morality and science, with special emphasis on fertilization, will have to play a more integral role
Inverse type II seesaw mechanism and its signature at the LHC and ILC
The advent of the LHC, and the proposal of building future colliders as the
ILC, both programmed to explore new physics at the TeV scale, justifies the
recent interest in studying all kind of seesaw mechanisms whose signature lies
on such energy scale. The natural candidate for this kind of seesaw mechanism
is the inverse one. The conventional inverse seesaw mechanism is implemented in
an arrangement involving six new heavy neutrinos in addition to the three
standard ones. In this paper we develop the inverse seesaw mechanism based on
Higgs triplet model and probe its signature at the LHC and ILC. We argue that
the conjoint analysis of the LHC together with the ILC may confirm the
mechanism and, perhaps, infer the hierarchy of the neutrino masses.Comment: 24 pages, 22 figure
The Unborn and A, B, & C v Ireland
From text: A, B, and C v Ireland (ABC-case) arose from an application lodged on 15 July 2005 to the European Court of Human Rights, which was directly referred to the Grand Chambers (thus indicating the importance of the case) for a hearing which commenced on 9 December 2009
Does e-learning policy drive change in Higher Education?: A case study relating models of organisational change to e-learning implementation
Due to the heightened competition introduced by the potential global market and the need for structural changes within organisations delivering e-content, e-learning policy is beginning to take on a more significant role within the context of educational policy per se. For this reason, it is becoming increasingly important to establish what effect such policies have and how they are achieved. This paper addresses this question, illustrating five ways in which change is understood (Fordist, evolutionary, ecological, community of practice and discourse-oriented) and then using this range of perspectives to explore how e-learning policy drives change (both organisational and pedagogic) within a selected higher education institution. The implications of this case are then discussed, and both methodological and pragmatic conclusions are drawn, considering the relative insights offered by the models and ways in which change around e-learning might be supported or promoted
Avaliação de porta-enxertos em combinação com copas comerciais de laranjeiras em Rio Branco, Acre.
Tamanho amostral envolvendo múltiplos caracteres: uma aplicação à digestibilidade em bovinos.
0 objetivo deste trabalho foi estimar o tamanho amostral mínimo (n) para comparar tratamentos em experimentos de consumo e de digestibilidade com bovinos, envolvendo múltiploscaracteres. Foram utilizados dados de digestibilidade de 72 novilhas com média de 18 meses de idade e 250 kg de peso. 0 experimento foi realizado na Embrapa-Centro de Pesquisa de Pecuária do Sudeste, Sao Carlos, SP, de 1988 a 1989, em delineamento inteiramente casualizado, com nove tratamentos organizados em esquema fatorial 3 x 3 (tres grupos genéticos: Canchim, % Canchim+ % Nelore e Nelore, e tres niveis de proteina bruta: 6, 10 e 13%, com oito repetigbes cada, sendo a unidade ,experimental a novilha). Foram analisados consumo de ragho (g/kg'") por quilograma de peso metabolico, energia digestivel, nitrogenio retido (NR), NR (mg/kg'") e digestibilidades da matéria seca, proteina bruta, fibra em detergente neutro e fibra em detergente acido. 0 valor minimo de n, que permite detectar diferenças significativas (h) entre vetores de médias de tratamentos, foi obtido por meio de um programa SAS (Statistical Analysis System), considerando modelo de distribuição normal t-variada, média zero e matriz de covariåncia Z, estatística T' de Hotelling, distribuído F com parâmetro de nRo centralidade (5' ), erros do tipo I (a), poder do teste (1-p) e A. 0 valor de n variou de 6 a 47, sendo mais influenciado por alteração nos valores de 6, do que nos valores de a e poder do teste
