Fractals and scaling in fracture induced by microcrack coalescence

A numerical model is proposed to simulate fracture induced by the coalescence of numerous microcracks, in which the condition for coalescence between two randomly nucleated microcracks is determined in terms of a load-sharing principle. The results of the simulation show that, as the number density of nucleated microcracks increases, stochastic coalescence first occurs followed by a small fluctuation, and finally a newly nucleated microcrack triggers a cascade coalescence of microcracks resulting in catastrophic failure. The fracture profiles exhibit self-affine fractal characteristics with a universal roughness exponent, but the critical damage threshold is sensitive to details of the model. The spatiotemporal distribution of nucleated microcracks in the vicinity of critical failure follows a power-law behaviour, which implies that the microcrack system may evolve to a critical state.     

Stereotypical attitudes amongst black students at a rural historically black South African university

This study investigated stereotypical attitudes towards race amongst Black students (N=274) attending a historically Black South African university (females=62%; mean age of 22.15 years; SD=3.00 years). Data on group stereotyping by race were collected using a semi-structured questionnaire. The data were analysed for themes using discourse analysis. The findings indicated that Black students from a rural background stereotyped those from urban centres as lacking in African culture and being overly westernised. Conversely, rural Blacks from urban settings stereotyped those from rural areas as respectful, cultured and materially poor. Regardless of geographical origin, the Black students perceived English-speaking Whites as competent and friendly, while Afrikaans-speaking Whites were stereotyped as racist, aggressive and hardworking. The Black students perceived Indian South Africans as unethical and deceitful whilst Coloureds were noted to lack culture and to be aggressive. Findings suggest stereotypical racist language or discourse to be persistent among a student population with historical disadvantage.     

Divine Action,Resurrection, and the Transformation of the Universe

Abstract

The article examines the notion of self-organization and explores the reality of biological processes from an epistemological point of view. First, I briefly analyze what is currently regarded as one of the most important discoveries not only in physics, but also in biology—namely, complex systems and deterministic chaos; secondly, I offer some reflections on the new frontiers of contemporary biology— namely, functional genomics and systems biology. The central part of the article focuses on the epistemological transition from genetic determinism to the new conception of “meaning” as emergence.     

Reconsidering the aims of analysis in a probabilistic universe: Containment and coniunctio

Abstract

This paper explores the relationship between our attempts to define the aims of analysis and the acceptance of probability in New Physics. It draws attention to the influence of physicists on both Jung and Bion, which is well documented. It presents an argument for process-based aims rather than the recognition of innate knowledge as an aim. Two processes from different traditions (Jungian and Kleinian) are suggested as central to the aims of analysis: containment and coniunctio. The coniunctio/disiunctio axis in Jung's writing is paralleled with the axis PS<->D of the post-Kleinians. Clinical material is presented supporting the necessity of differential aims and illustrating development/stasis along this axis. A case is made for analysis to embrace the reality of uncertainty and to work with the psychic obstacles in patients, and in analysts, that result from coming to terms with probability.     

‘New Age’ revisited: By way of entry into restorative justice

The present article pursues striking similarities between the discourse of philosophies and practices often categorised as ‘New Age’, and that of restorative justice. By bringing observations from data material produced in seemingly very different fields of research to a close encounter, a common discourse of transformation is tentatively explored, adding to contemporary works that warn against assuming ‘New Age’ as a sui generis movement or milieu. The article is an exercise in tracing connections across different fields of study, lending support to the claim that such tracing may contribute to the opening out of our topic in ways that have implications for what we can understand as constituting a social environment, for what we can understand as constituting context, for what we can understand as constituting ‘New Age’.     

Logotherapy and Pastoral Counseling

SUMMARY

An intensive study of Frankl's logotherapy reveals its timely relevance for pastoral counseling. The paradigm of logotherapy recognizes the spiritual dimension as the inclusive and encompassing dimension for comprehending and integrating human phenomena. Its hermeneutical phenomenological analysis introduces an understanding of personhood which affirms one's capacity to find meaning in life, indeed, even in suffering and dying. It is this unique spiritual capacity which conveys a renewed awareness of self worth and human dignity and assists persons in understanding themselves as fashioned in the image of God. Logotherapy provides a helpful counseling theory for pastors and laity engaged in older adult ministry.     

A behavioural experiment in virtual reality to verify the role of action function in space coding

Neurophysiological data indicate that the reachable peripersonal space and the unreachable extrapersonal space are represented in segregated parietofrontal circuits and that when the unreachable space becomes reachable because of tool use, it is automatically coded by the network selective for peripersonal space. Here we directly tested the role of action's consequences in space coding. Thirty-eight participants bisected lines at either a reachable distance (60 cm) or unreachable distance (120 cm) using either a laser pointer or laser cutter. The laser cutter but not the laser pointer had an action consequence; the line broke into two pieces. The results showed that distance moderated the effect of action. At an unreachable distance, the mean bisection point was closer to the centre when participants used the laser cutter compared to when they used the laser pointer. There were no differences at a reachable distance (60 cm). This result suggests that the space in which the individual may determine a physical consequence is categorized as peripersonal space, independently from its actual distance from the individual's body.     

How people think “if only …” about reasons for actions

When people think about how a situation might have turned out differently, they tend to imagine counterfactual alternatives to their actions. We report the results of three experiments which show that people imagine alternatives to actions differently when they know about a reason for the action. The first experiment (n = 36) compared reason – action sequences to cause – effect sequences. It showed that people do not imagine alternatives to reasons in the way they imagine alternatives to causes: they imagine an alternative to an action more than an effect, and to a cause more than a reason. The second experiment (n = 214) and the third experiment (n = 190) both show that different sorts of reasons have different sorts of effects on how people imagine alternatives to actions. People imagine an alternative to an action (the protagonist went to a ball) less often when they know the reason for the action was an obligation (he had to participate in fundraising) compared to when they know about a weaker reason (he wanted to meet a famous violinist) or no reason. The second experiment shows the effect for a social obligation and the third experiment replicates and extends it to a health obligation. We interpret the results in terms of the possibilities that people keep in mind about actions and their reasons.     

Coping with major life events: the role of spirituality and self-transformation

The aim of the current study was to explore the process of self-transformation as a result of coping with a major life event, and to address the role, if any, that spirituality plays within the coping and transformational process. Using grounded theory methodology, six participants were interviewed over a period of 6 months. The findings, supportive of previous research, produced a preliminary model illustrating transformation as a gradual process. The core category was identified as “openness,” in that by being open to others or to the “Transcendent,” the participants were able to let go and transform. It was theorized that openness, in this sense, enables acceptance of material deriving from a realm of self beyond the everyday ego. Indeed, such a journey of transformation crucially seems to entail expanding the conception of self beyond customary limits. Understood in this way, transformation may be conceptualized as a process of continual movement into the unconscious, where the totality of the self is awakened, resulting in a reinterpretation of life purpose. The consequences of the transformation for participants were positive in nature. The role that spirituality plays within the coping and transformation process was seen to manifest as being subtle and unfolding and/or supportive.     

Towards an Understanding of Nurturing and Restraining Relational Patterns in School Communities

This study aimed to understand the nature of nurturing and restraining relationships in a school communiy. The inquiry entailed a single instrumental case study of a selected school community in a semi-urban context in South Africa. Participants were learners (n=720), teachers (n=33) and administrative and terrain staff members (N=8) as well as two parents. Data on participants' perceptions of relationships in the school community were collected using work sessions/nominal group techniques, visual representations, and focus group interviews. Thematic analysis of the data revealed connectedness, respect, care and transparent communication as aspects that nurture relationships. Limited connectedness between people, the abuse of power, shifting of responsibility and disrespect for one another were revealed as aspects that restrain relationships.
