The self-avoiding walk is a classical model in statistical mechanics, probability theory and mathematical physics. It is also a simple model of polymer entropy which is useful in modelling phase behaviour in polymers. This monograph provides an authoritative examination of interacting self-avoiding walks, presenting aspects of the thermodynamic limit, phase behaviour, scaling and critical exponents for lattice polygons, lattice animals and surfaces. It also includes a comprehensive account of constructive methods in models of adsorbing, collapsing, and pulled walks, animals and (...) networks, and for models of walks in confined geometries. Additional topics include scaling, knotting in lattice polygons, generating function methods for directed models of walks and polygons, and an introduction to the Edwards model.This essential second edition includes recent breakthroughs in the field, as well as maintaining the older but still relevant topics. New chapters include an expanded presentation of directed models, an exploration of methods and results for the hexagonal lattice, and a chapter devoted to the Monte Carlo methods. (shrink)

In Ontario, Canada, autism has become widely politicized. In the last 20 years, instances of personal and organizational advocacy developed into wider-scale policy and programs. Government press releases indicate Ontario’s developing response to autism as a social policy issue, while reflecting societal perceptions and priorities surrounding autism. Informed by Critical Disability Studies and Critical Autism Studies, this article uses a content analysis to explore the manifest and latent priorities of Ontario’s provincial government displayed in press releases between 2001-2019 accessed through (...) the Ontario Newsroom, an online repository of press releases and media advisories that features different initiatives published by the government of Ontario. Press releases were selected based on the search term “autism” and analyzed in two steps. First, this article presents the most frequently used words in press release headlines. Second, key themes within press releases are explored. Press releases emphasize the stories of non-autistic people, altruists, positivists, treatment-seekers, autistic children, and normative families. What is left out is a social representation of autism. Prominent themes display ableist perceptions of autism, reproducing power imbalances and inequity based on disability and family status. These findings reveal government objectives and priorities, reflecting broader societal perceptions of autism. (shrink)

It has been made clear for quite some time that if the Bible has become a classic of Western culture because of its normativity, then the responsibility of the biblical scholar cannot be restricted to giving readers clear access to the original intentions of the biblical writers. It must also include the question: ‘What does a reading of the biblical text do to someone who submits to its world of vision?’ This is a question that has been especially significant in (...) the study of apocalyptic literature, as all apocalypses are hortatory. The implication is that, even in the historical context in which the text was first produced, there is room to consider the earliest stages of audience interaction with the text. Interestingly, most studies making use of this model do not address what the implications of this kind of ‘reading as performance’ might be for today’s reader. This research argued that in the understanding of the biblical text as an oral performance, there is a need to leave room for all that happens to a text after it leaves the author’s hands. The method proposed urged ‘performers’ of texts to pay attention to how they bring themselves to interpretation. More specifically, this method aimed to make use of ritual and liturgy as the rhetorical or performative context within which biblical texts functioned and still function. This research thus proposed a liturgical-functional reading reading of biblical texts which integrates affective reading and the deliberate move from cognitive to affective processes. (shrink)

This article was motivated by the need to academically frame and share the response of the North-West University to the perceived increase of academic dishonesty during Covid-19. Within the ambit of the online teaching and learning approach that became dominant during the Covid-19 pandemic, the NWU established a Community of Practice for Academic Integrity to enhance Academic Integrity in a holistic manner. By critically discussing the NWU’s response through their CoPAI, the lessons learned, and strategies developed in the process, the (...) NWU can hopefully assist other Higher Education institutes to progressively enhance AI in the future. This is important, because many contextual shifts in teaching and learning approaches, pedagogy, assessment, and the application of technology, that were enforced in an online mode of delivery during the pandemic, will prevail in future.In writing this article, we focused on contextualising the NWU CoPAI within current literature on community of practice and Academic integrity and emphasising the unique strategy and holistic nature of this CoPAI. The establishment of the CoPAI is discussed within the appreciative inquiry as methodological framework. This methodology is commonly used by CoPs, but it is particularly relevant to the CoPAI since CoPAI sought answers to all the AI questions that presented itself due to disruptions in the higher education landscape. The appreciative inquiry method allowed for the opportunity to find some answers in a holistic manner. Some of these answers or insights gained through the activities of CoPAI is further discussed in the latter part of the article. In conclusion, some of the outcomes and shortcomings of CoPAI at the NWU are highlighted.The main finding of this article concluded that the establishment of a CoPAI can enhance AI at HE institutions in a holistic manner. The applicability, relevance, and success of this CoPAI was realised through its holistic approach which included the valorisation of institutional aspects, the engagement and empowerment of lecturers, and the engagement and empowerment of students. This novel and unique approach to promote AI in HE could fill the existing knowledge gap in the South African context, where the establishment of a CoPAI, the application of appreciative inquiry as methodology, and the inclusion of a holistic approach are still absent. It might however also be an example for other HE institutions to follow globally. (shrink)

The coronavirus disease 2019 (COVID-19) pandemic has again confirmed our obsession with, and misuse of, the Book of Revelation. Of course, this is definitely not the first time that Revelation’s themes and imagery have been pulled out and used to try and explain the current situation. In fact, the Book of Revelation is well-known as ‘the’ book of the New Testament where information about the present as well as the future can be found. Unfortunately, in situations like these, people simply (...) do not bother to draw from the reservoir of experiences on which the author of Revelation naturally expected his hearer or reader to draw. This phenomenon is made worse by the fact that the primary study of the text has moved into the academic institution and, by inference, away from the faith movement. This may make earnest scholarly biblical study of the Apocalypse seem irrelevant to the general concerns of the faith community and the world. But the Book of Revelation does provide an indispensable resource for helping Christians conceive of their place in the contemporary world and meditate on the role the church is to play in a modern, secular society. John’s Apocalypse is not a mere nostalgic trip down memory lane; it is a form of anamnesis or recollection – in recalling or performing the narrative, the past is made physically present. By way of a performative reading of the Book of Revelation, this article makes use of a more practical exegetical dimension. Contribution: This method brings the Apocalypse as New Testament text back into the life of the community of faith it belongs to and should be performed in, thus also increasing the usage and impact of the Book of Revelation in the faith community.

Intergenerational trauma research typically focuses on parent survivors. No specific guidelines are available for conducting research with parent survivors despite potentially unique risks. To investigate research safety with parent survivors, we conducted an online survey of 38 researchers regarding experiences of parent survivors in their research, precautions taken, ethical review experiences, and researchers’ mental health during the project(s). Most researchers felt that parent survivors are a unique population that require extra support. However, the response rate was low. Findings show the (...) need for specific research guidelines informed by parent survivors’ lived experiences, and to support researchers against vicarious traumatic stress. (shrink)

Several important ethical dilemmas emerge when nurses join a public-sector strike. Such industrial action is commonplace in South Africa and was most notably illustrated by a national wage negotiation in 2010. Media coverage of the proceedings suggested unethical behaviour on the part of nurses, and further exploration is merited. Laws, policies and provisional codes are meant to guide nurses’ behaviour during industrial action, while ethical theories can be used to further illuminate the role of nurses in industrial action. There are, (...) however, important aspects to consider before judging whether nurses act unethically when striking. Following Loewy’s suggestion that the nature of the work, the proceeding commitment of the nurse to the patient, the prevailing situation when the strike is planned and the person(s) who stand(s) to benefit from the strike be considered, coupled with a consideration of the South African historical socio-political context, important aspects of the ethics of nurses’ behaviour in industrial action transpire.

The Heidelberg Catechism was one of many catechisms that originated during the 16th-centuryReformation. It is also known that the authors of the Heidelberg Catechism made use of existingcatechisms. The content of 16th-century catechisms consisted mainly of the Decalogue, theApostolicum and the Lord’s Prayer. The Heidelberg Catechism starts with the famousintroduction, dealing with man’s only comfort, and in three sections with knowledge of our sinand misery, knowledge of our deliverance, and knowledge of how we should be grateful forour deliverance. This contribution (...) points out that the threefold structure of the HeidelbergCatechism is not unique, but appeared in different ways in different catechisms of prominent16th-century reformers. It is also argued that the Heidelberg Catechism should be read againstLutheran and Calvinistic backgrounds. Finally, it is shown that the Heidelberg Catechismarticulated the basic Christian faith in such a beautiful and poignant manner that it stood thetest of time as a catechism and confession. (shrink)

Literature on Shared Mental Models has been burgeoning in recent years and this has provided increasingly detailed insight and evidence into the importance of SMMs within specific contexts. However, because past research predominantly focused on SMM structure as measured by diverse, context-dependent measures, a consolidated multi-dimensional measure of perceived SMMs that can be used across diverse team contexts is currently lacking. Furthermore, different conceptualizations of the dimensionality of SMMs exist, which further impedes the comparison between studies. These key limitations might (...) hinder future development in the SMM literature. We argue that the field of SMMs has now matured enough that it is possible to take a deductive approach and evaluate the prior studies in order to refine the key SMMs dimensions, operationalizations, and measurement. Hence, we take a three-stage approach to consolidate existing literature scale-based measures of SMMs, using four samples. Ultimately, this leads to a 20-item five-dimensional scale – the Five Factor Perceived Shared Mental Model Scale. Our scale provides scholars with a tool which enables the measurement, and comparison, of SMMs across diverse team contexts. It offers practitioners the option to more straightforwardly assess perceived SMMs in their teams, allowing the identification of challenges in their teams and facilitating the design of appropriate interventions.

ABSTRACT Health practitioners run the risk of ethical board complaints or legal action against them in their professional careers. This experience can have a detrimental impact on personal wellness and professional practice. This study reports on the subjective experience of ten South African psychologists who received complaints. Semi structured interviews were conducted, and the transcripts analyzed using interpretative phenomenological analysis. The data indicates that the participants experienced the effects of a complaint on an intensely personal level and the experience of (...) a complaint highlighted the challenging nature of working in the modern health care arena. The researchers hope to inform the psychological community of the emotional challenges experienced during a complaint process, to encourage a transparent discourse about the subject and muster support for practitioners during an often-isolating professional incident.

According to Peter van Inwagen, visible inanimate objects do not, strictly speaking, exist. In defending this controversial thesis, he offers fresh insights on such topics as personal identity, commonsense belief, existence over time, the phenomenon of vagueness, and the relation between metaphysics and ordinary language.

Lara Buchak argues that her version of rank-weighted utilitarianism can accommodate an implication of the separateness of persons known as “the shift,” since it requires individuals to be more willing to accept risk for themselves than to accept inequality in society. I argue that this is mistaken. Buchak’s model fails to yield the shift when the decision-maker is distinct from the affected individual, as well as in certain social decisions where the risk attitude of the group is known. These findings (...) suggest that models which derive social choice rules from individual decision rules will generally fail to uphold separateness. (shrink)

### ­ In Who shall go first? A multicriteria approach to patient selection for first clinical trials of cardiac xenotransplantation, Kögel et al recommend the inclusion of patients who (1) have a (high) medical need for an allograft, (2) have the capacity to benefit from a xenograft, (3) have a ‘real’ choice between enrolment in a first-in-human clinical trial and an alternative life-sustaining treatment option and (4) have no clear record of previous non-compliance.1 As the authors discuss, patient selection must (...) promote the goal of gaining reliable and valid knowledge about the risks and benefits of cardiac xenotransplantation. While the four criteria outlined above certainly promote this goal, we argue it is crucial to add a fifth criterion emphasising the need to include diverse populations, particularly regarding sex, age, ethnicity and socioeconomic background.i In this commentary, we present two arguments for our claim and discuss the impact of neglecting diversity from the first trials on. ### The scientific rationale for including diverse populations First, including diverse populations in the first clinical trials of cardiac xenotransplantation enhances the scientific value of the data by assessing safety and efficacy among various populations. Treatment response can differ among patient (sub)groups as a result of genetic, physiological and socioeconomic factors.2 By including diverse populations from the first trials on, researchers can identify these ….

The aim of this article is to provide a preliminary ethical evaluation of the effect of telesurgery on patient care. In order to accomplish this task we give a broad description of the state of the art in telesurgery and analyse it using Joan Tronto’s articulation of care as a structured process. This structure illuminates the significance of the patient-physician relationship as the buttress for establishing and preserving practices of care in the healthcare context, with the ultimate goal of safeguarding (...) patient dignity. The process of care combined with the moral aim of medicine—to fulfil the good of the patient—provides the ethical foundation for assessing telesurgery. By exploring various telesurgical scenarios we may assess its potential role in augmenting or diminishing patient care within the frame of the patient-physician relationship. The significance of conducting this evaluation lies in the fact that the practice of telesurgery may very shortly become routine and an evaluation has not yet been attempted. (shrink)

The question of human control is a key concern in autonomous military systems debates. Our research qualitatively and quantitatively investigates values and concerns of the general public, as they relate to autonomous military systems, with particular attention to the value of human control. Using participatory value evaluation (PVE), we consulted 1980 Australians about which values matter in relation to two specific technologies: an autonomous minesweeping submarine and an autonomous drone that can drop bombs. Based on value sensitive design, participants were (...) tasked to enhance the systems with design features that can realize values. A restriction (limited budget) in each design task forced participants to make trade-offs between design options and the values that these options realize. Our results suggest that the ‘general public’ has diverse and nuanced stances on the question of human control over autonomous military systems. A third of participants that is opposed to autonomous military systems when asked directly, selected different combinations of design features realizing varying degrees of human control. Several contextual factors, technology-specific concerns, and certain values seemed to explain these different choices. Our research shows that a focus on human control might overlook other important values that the general public is concerned about, such as system reliability, verifiability, and retrievability.
