Although the demarginalisation of youths is an international concern, South African youths are viewed by various scholars and policy documents as a particularly vulnerable and marginalised group. It becomes essential to understand what characterises their marginalisation in order to find innovative ways to work towards their demarginalisation. In this article we reflect on current faith-based concerns and compare this with the specific characteristics of the marginalisation of young people. In an effort to contribute to the development of a strategy towards (...) demarginalisation, we will explore the key features of the Circle of Courage in terms of the principles of belonging, mastery, independence and generosity. We will further propose the inclusion of Ubuntu principles in the practical application of the Circle of Courage for churches and faith-based organisations in demarginalising youth in the South African context.

We generalize the concept of a cooperative non-transferable utility game by introducing a socially structured game. In a socially structured game every coalition of players can organize themselves according to one or more internal organizations to generate payoffs. Each admissible internal organization on a coalition yields a set of payoffs attainable by the members of this coalition. The strengths of the players within an internal organization depend on the structure of the internal organization and are represented by an exogenously given (...) power vector. More powerful players have the power to take away payoffs of the less powerful players as long as those latter players are not able to guarantee their payoffs by forming a different internal organization within some coalition in which they have more power.We introduce the socially stable core as a solution concept that contains those payoffs that are both stable in an economic sense, i.e., belong to the core of the underlying cooperative game, and stable in a social sense, i.e., payoffs are sustained by a collection of internal organizations of coalitions for which power is distributed over all players in a balanced way. The socially stable core is a subset and therefore a refinement of the core. We show by means of examples that in many cases the socially stable core is a very small subset of the core.We will state conditions for which the socially stable core is non-empty. In order to derive this result, we formulate a new intersection theorem that generalizes the KKMS intersection theorem. We also discuss the relationship between social stability and the wellknown concept of balancedness for NTU-games, a sufficient condition for non-emptiness of the core. In particular we give an example of a socially structured game that satisfies social stability and therefore has a non-empty core, but whose induced NTU-game does not satisfy balancedness in the general sense of Billera.

Today’s students are accustomed to a world where information is available on-demand, anywhere and anytime. They bring this expectation to their academic world where they want to work cooperatively and flexibly, using the modern information processing tools and access with which they are familiar. New hardware platforms such as e-Readers and tablet computers have made substantial inroads in the consumer market. E-Readers are becoming more prevalent in universities – replacing the need for physical textbooks, lecturing notes and other academic documents. (...) Many universities are now running pilot programs, while some are already using e-Readers. Tablet computers, apart from their ability to read, edit or create various types of information documents, also offer additional features such as collaborative and social networking services. This empirical research project investigated student perspectives on the educational use of e-Readers and tablets within the University of Cape Town. A questionnaire was distributed to a significant portion of the student population and stratified according to seniority and faculty. Quantitative data was gathered and analysed on themes ranging from awareness to preferences to facilitating conditions around e-Readers within the academic environment. The students sent a clear signal: that they are keen to embrace these new technologies and the advantages they offer. E-Books can be updated automatically and downloaded to e-Readers instantly from almost anywhere in the world. Students feel they would benefit greatly through the use of e-Readers and many believe they are set to replace books completely. Having access to a portable library of information in their backpacks would benefit both students and the environment. However, there are a number of barriers to the comprehensive introduction of these technologies, including the cost of the devices; cost, rights and file format of e-books; the need for a critical mass of textbooks available in digital format and device characteristics such as battery life, and ubiquitous Wi-Fi access.

The aim of the article is to report on research findings that could contribute to the development of decolonised academic material. Africanisation of curricula implies that education and training as well as praxis be informed by the reality of the South African context, the viewpoints of the people of South Africa and their descriptions of what is needed to build a just society. This is relevant to a variety of service professions. This article was presented from a trans-disciplinary framework, and (...) the term ‘professional carers’, including the social service and theology professions, was used. The discussion explored how academia can approach the development of curricula that will inform praxis and which is relevant to the African context. The terms ‘Africanisation’, ‘decolonisation’ and ‘contextualisation’ were linked, whereafter a developmental approach to the development of the content and presentation of academic material was proposed. The article is concluded with recommended strategic options for the development of Africanised curricula. (shrink)

ABSTRACT The principle of informed refusal poses a specific problem when it is invoked by a pregnant woman who, in spite of having accepted her pregnancy, refuses the diagnostic and/or therapeutic measures that would ensure the well‐being of her endangered fetus. Guidelines issued by professional bodies in the developed world are conflicting: either they allow autonomy and informed consent to be overruled to the benefit of the fetus, or they recommend the full respect of these principles. A number of medical (...) ethicists advocate the overruling of alleged irrational or unreasonable refusal for the benefit of the fetus. The present essay supports the view of fetal rights to health and to life based on the principle that an ‘accepted’ fetus is a ‘third person’. In developing countries, however, the implementation of the latter principle is likely to be in conflict with a ‘communitarian’ perception of the individual – in this case, the pregnant woman. Within the scope of the limitations to the right to autonomy of J.S. Mill's ‘harm principle’, the South African Patients’ Charter makes provision for informed refusal. The fact that, in practice, it is not implemented illustrates the well‐known difficulty of applying Western bioethical principles in real life in the developing world. (shrink)

Largely, the concept of energy or vital force, as first analysed by Placide Tempels in Bantu Philosophy, permeates most African ontology systems, worldviews and life views. The Ntomba Chief is chosen because of his above average vital force. This puts him in the position of intermediary between the Supreme Being, the ancestors, and his subordinates. The waning of his energy is incompatible with his position because his energy is that of his tribe. When installed, he takes an oath that, when (...) this happens, he has to accept mohilo, the ‘hastening of death’. In the Chief's case, the hastening of death is not intended to relieve his pain, as it would be with other creatures. The Chief's dying a natural death would result in the loss of the entire community's vital force. Therefore, he has to be killed ritually to avoid that risk. That the Chief agrees to be killed – via a form of advanced directive – poses an ethical dilemma for a Western observer. From the Ntomba perspective, however, where the energy is being, and being is energy, it is the only way to preserve and protect the community's raison d’être. (shrink)

Approximately three decades ago the question was first answered whether parasitoids are able to assess the number or origin of eggs in a host for a solitary parasitoid, Leptopilina heterotoma, by fitting theoretically derived distributions to empirical ones. We extend the set of different theoretically postulated distributions of eggs among hosts by combining searching modes and abilities in assessing host quality. In the models, parasitoids search either randomly (Poisson) (1) or by vibrotaxis (Negative Binomial) (2). Parasitoids are: (a) assumed to (...) treat all hosts equally, (b) able to distinguish them in unparasitised and parasitised hosts only, (c) able to distinguish them by the number of eggs they contained, or (d) able to recognise their own eggs. Mathematically tractable combinations of searching mode (1 and 2) and abilities (a,b,c,d) result in seven different models (M1a, M1b, M1c, M1d, M2a, M2b and M2c). These models have been simulated for a varying number of searching parasitoids and various mean numbers of eggs per host. Each resulting distribution is fitted to all theoretical models. The model with the minimum Akaike's information criterion (AIC) is chosen as the best fitting for each simulated distribution. We thus investigate the power of the AIC and for each distribution with a specified mean number of eggs per host we derive a frequency distribution for classification.Firstly, we discuss the simulations of models including random search (M1a, M1b, M1c and M1d). For M1a, M1c and M1d the simulated distributions are correctly classified in at least 70% of all cases. However, in a few cases model M1b is only properly classified for intermediate mean values of eggs per host. The models including vibrotaxis as searching behaviour (M2a, M2b and M2c) cannot be distinguished from those with random search if the mean number of eggs per host is low. Among the models incorporating vibrotaxis the three abilities are detected analogously as in models with random search. (shrink)

This article deals with the concept of sentience, and more specifically with the argument from sentience as it is used by utilitarians in the abortion debate and in the advocacy of animal rights. It is argued that sentience is more than feeling pleasure and pain (with empha sis on pain), and that pain is an inborn protection required to fit into the world rather than the substance of evil. S. Afr. J. Philos. Vol.23(3) 2004: 292-301.

With the proliferation of networked electronic communication came daunting capabilities to collect, process, combine and store data, resulting in hitherto unseen transformational pressure on the concepts of trust, security and privacy as we know them. The Future Internet will bring about a world where real life will integrate physical and digital life. Technology development for data linking and mining, together with unseen data collection, will lead to unwarranted access to personal data, and hence, privacy intrusion. Trust and identity lie at (...) the basis of many human interactions and transactions, and societies have developed legitimate concern for privacy being essential for freedom and creativity. The burgeoning development of the Information Society, particularly during the past fifteen years, transcended the societal readiness to respond to the transformational change evoked by ICT. We have reached the eleventh hour for the preservation of trust and privacy as elements that can be transposed into our digital future. Europe has been at the forefront in recognizing the importance of privacy protection in relation to digital data, witness the advanced European legislation in this domain. The European Commission recognizes that appropriate measures need to combine technology development with legal means, user awareness and tools supporting data controllers to comply with law in an accountable and transparent way, and that empower users with a controlling stake in managing their personal data. Activities are underway at many levels. European RTD programmes play their role in supporting research in trustworthy ICT, privacy enhancing technologies, privacy-by-design in service layers as well as in networks, enabling technologies such as cryptography, and in generalized frameworks for trust and privacy-protective identity management.

This article studies the rewriting of the second creation narrative in the Bible in Jubilees 3:1-31. It shows that the author of Jubilees 3 is not only putting his own views into the biblical text. He is in the first place a careful reader of Genesis 2-3 and other biblical texts. The biblical text posed some difficulties to him and he tries to solve many of these with his rewriting. Characteristic of this rewriting is especially harmonisation. Sometimes he supplies details (...) for explaining the text. The point of departure is most often the biblical text itself, although, at the same time, he seemed to be influenced by current interpretations of certain aspects of the text. (shrink)

Studies on transposable elements of the Ac family have led to different models for excision gap repair in either plants or Drosophila. Excision products generated by the plant transposable elements Ac and Tam3 imply a more or less straightforward ligation of broken ends; excision products of the Drosophila P element indicate the involvement of ‘double‐strand break’ (DSB) repair. Recent findings that excision products of Ac and Tam3 can also contain traces of the element ends indicate, however, that DSB repair might (...) be an alternative repair mechanism in plants. A functional DSB repair mechanism in plants can also be deduced from the observed rapid increases of Ac copy number during plant development and from the involvement of Ac in the generation of internal Ac deletions. On the other hand, alternative repair mechanisms may also be functional in Drosophila, because some of the ‘footprints’ generated upon P excision can be explained by a mechanism that has been postulated for excision gap repair in plants. It is concluded that plants and Drosophila can use similar repair mechanisms, but that the predominance of a certain repair mechanism is determined by the host. (shrink)

The recent widespread shift in governance from the state to the market and to civil society, in combination with the simultaneous shift from the national level to supra-national and sub-national levels has led to a significant increase in the numbers of public and private players in nature policy. This in turn has increased the need for a common vocabulary to articulate and communicate views and values concerning nature among various actors acting on different administrative levels. In this article, we will (...) examine the role of concepts of nature as communicative devices in public debates and political decision-making. We try to show that the now dominant functionalist approach to concepts of nature, due to its focus on interests, threatens to narrow public and political communications to purely strategic negotiations. Instead of this functionalist approach we put forward a structuralist approach, which focuses not on interests but on values. (shrink)

We study increasing F-sequences, where F is a dilator: an increasing F-sequence is a sequence (indexed by ordinal numbers) of ordinal numbers, starting with 0 and terminating at the first step x where F(x) is reached (at every step x + 1 we use the same process as in decreasing F-sequences, cf. [2], but with "+ 1" instead of "- 1"). By induction on dilators, we shall prove that every increasing F-sequence terminates and moreover we can determine for every dilator (...) F the point where the increasing F-sequence terminates. We apply these results to inverse Goodstein sequences, i.e. increasing (1 + Id) (ω) -sequences. We show that the theorem every inverse Goodstein sequence terminates (a combinatorial theorem about ordinal numbers) is not provable in ID 1 . For a general presentation of the results stated in this paper, see [1]. We use notions and results concerning the category ON (ordinal numbers), dilators and bilators, summarized in [2, pp. 25-31].
