Deep neural networks (DNNs) have had extraordinary successes in classifying photographic images of objects and are often described as the best models of biological vision. This conclusion is largely based on three sets of findings: (1) DNNs are more accurate than any other model in classifying images taken from various datasets, (2) DNNs do the best job in predicting the pattern of human errors in classifying objects taken from various behavioral datasets, and (3) DNNs do the best job in predicting (...) brain signals in response to images taken from various brain datasets (e.g., single cell responses or fMRI data). However, these behavioral and brain datasets do not test hypotheses regarding what features are contributing to good predictions and we show that the predictions may be mediated by DNNs that share little overlap with biological vision. More problematically, we show that DNNs account for almost no results from psychological research. This contradicts the common claim that DNNs are good, let alone the best, models of human object recognition. We argue that theorists interested in developing biologically plausible models of human vision need to direct their attention to explaining psychological findings. More generally, theorists need to build models that explain the results of experiments that manipulate independent variables designed to test hypotheses rather than compete on making the best predictions. We conclude by briefly summarizing various promising modeling approaches that focus on psychological data. (shrink)

The findings of an empirical study entitled ‘Meeting the challenge of poverty and inequality in the Cape Metropole: Factors impacting the mobilisation of congregations in their response to poverty and injustice’ reaffirm that the majority of congregations are still largely operating within a ‘relief and welfare’ paradigm with regard to poverty. In attempting to analyse the hindrances to churches’ mobilisation in addressing poverty from a holistic perspective, it became clear that, while there were common challenges, several other intersectional issues also (...) play a role with regard to engagement. This article, therefore, analyses and discusses how these factors have an impact on the mobilisation of local congregations in their response to the twin challenge of poverty and inequality.

South Africa remains one of the most unequal societies in the world and any discussion around poverty and the church's response cannot exclude this reality. This article attempts to analyse the response of wealthy, 'majority white' suburban congregations in the southern suburbs of Cape Town to issues of poverty and inequality. This is attempted through the lense of restorative justice, which is broadly explored and defined through a threefold perspective of reconciliation, reparations and restitution. The first part explores a description (...) of the basic features of poverty and inequality in South Africa today, followed by a discussion on restorative justice. This is followed by the case study, which gives the views of clergy and lay leaders with regard to their congregations' perspectives and responses to poverty and inequality within the context of restorative justice. Findings from the case study begin to plot a tentative 'way forward' as to how our reality can more constructively be engaged from the perspective of congregational involvement in reconstruction of our society.

Written in debate format, this book covers developing fields such as social cognition, as well as classic areas such as memory, learning, perception and categorization. The links between emotion and memory, learning, perception, categorization, social judgements, and behavior are addressed.

One of the most pressing issues in the urban ghettos of the Cape Flats is that of gangsterism and the discourse of power and powerlessness that is its lifeblood. Media coverage over the past two years was littered with news on gangsterism as the City of Cape Town struggles to contain what some labelled a pandemic. It is a pandemic that is closely tied to a deprivation trap of poverty, marginalisation, isolation, unemployment and, ultimately, powerlessness. The latter concept of powerlessness (...) and its interplay with these factors constituted the main thrust of this article as it explores the concept of power as deeply relational with the economic, psycho-social and spiritual dimensions. It is proposed that Kingdom power challenges the status quo within such contexts and offers the church an alternative framework within which to engage prophetically. (shrink)

In this volume specialists of medieval music and philosophy put the medieval 'musica' into the context of ideas and institutions in which it existed. The significance of 'musica' cannot be understood from a modern point of view since 'music' does not match the medieval 'musica'.

On several key issues we agree with the commentators. Perhaps most importantly, everyone seems to agree that psychology has an important role to play in building better models of human vision, and (most) everyone agrees (including us) that deep neural networks (DNNs) will play an important role in modelling human vision going forward. But there are also disagreements about what models are for, how DNN–human correspondences should be evaluated, the value of alternative modelling approaches, and impact of marketing hype in (...) the literature. In our view, these latter issues are contributing to many unjustified claims regarding DNN–human correspondences in vision and other domains of cognition. We explore all these issues in this response. (shrink)

Faith-based Organisations have been at the forefront of a growing interest of the intersection between religion and development. Their value has been recognised as both pragmatic and, perhaps more contentiously, also 'spiritual' in nature because of advantages arising from faith itself. For many FBOs, religion is far more than an 'essential component of identity … it is a source of well-being'. In this manner, FBOs challenge the modernist assumptions of traditional development theory, which view the spiritual and physical domains as (...) separate. In fact, for some FBOs, 'spiritual faith provides the fuel for action'. This paper reports on an aspect of the empirical findings of a South African study and explores both the way in which Christian FBOs understand their Christian identity and the way in which they articulate this through their use of scripture as a motivating or an envisioning tool.

The study conducted in 2017, in the Cape Metropole to explore the nature of partnership between local congregations and Christian Development Organisations, entitled, ‘Enhanced partnership between local congregations and Faith-based Organisations: towards a holistic congregational praxis’ reveal that, there are enough collaboration efforts between these two entities of the church. These efforts revolve around issues, such as spiritual support, volunteerism and discipleship. The view is that, even though elements of partnership such as volunteerism, prayer and discipleship are essential in the (...) journey of development, there is a need for these efforts to be coupled by resources such as finances and expertise. Central to the argument of this paper is the view that says, enhanced partnership between local congregations and Christian Development Organisations has a potential to facilitate holistic congregational praxis. In most cases, these entities of the church are found in the same locality, and therefore need to define how they can together play a bigger and meaningful role in the transformation of their community. Bound by their faith mandate, working together as partners as opposed to competing with each other, they will find strength in each other, and portray good image of the Christian community in society. Guided by partnership ethos of trust, equality and mutual respect, they can both play a leading role in the nation-building project of South Africa. (shrink)

Bowers et al. rightly emphasise that deep learning models often fail to capture constraints on visual perception that have been discovered by previous research. However, the solution is not to discard deep learning altogether, but to design stimuli and tasks that more closely reflect the problems that biological vision evolved to solve, such as understanding scenes and preparing skilled action.

Objective: Deep brain stimulation targeted to the ventral intermediate nucleus of the thalamus is effective for motor symptoms in essential tremor, but there is limited data on cognitive outcomes. We examined cognitive outcomes in a large cohort of ET DBS patients.Methods: In a retrospective analysis, we used repeated-measures ANOVA testing to examine whether the age of tremor onset, age at DBS surgery, hemisphere side implanted with lead, unilateral vs. bilateral implantations, and presence of surgical complications influenced the cognitive outcomes. Neuropsychological (...) outcomes of interest were verbal memory, executive functioning, working memory, language functioning, visuospatial functioning, and general cognitive function.Results: We identified 50 ET DBS patients; 29 males; the mean age of tremor onset was 35.84 years with a median age of 38 years. The mean age at DBS was 68.18 years. There were 37 unilateral 30 left, seven right, and 13 bilateral brain implantations. In the subgroup analysis, there was a significant interaction between assessment and age of tremor onset ; F = 4.47; p = 0.043 for working memory. The post hoc testing found improvements for younger onset ET. Similarly, there was a significant interaction between assessment and complications vs. no complications subgroups; F = 4.34; p = 0.043 for verbal memory with worsening scores seen for ET patients with complications. The remaining tests were not significant.Conclusion: In this large cohort of ET patients with, DBS was not accompanied by a significant decline in many cognitive domains. These outcomes were possibly related to the selection of patients with normal cognitive functioning before surgery, unilateral DBS implantations for the majority, and selection of patients with optimal response to DBS.

This article explores how ministerial and leadership formation could be enabled to adopt transformational diaconia in addressing poverty in South Africa, engaging in ways in which pastoral care and leadership formation can respond to the addressing of poverty. The fact that transformation aims at changing the worldviews, paradigms and approaches to life and problem solving informs the author’s concept of transformational diaconia, which was proposed as an aspect of spiritual leadership capital (SLC), defined as, ‘The inner virtues afforded individuals by (...) their spirituality in formulating their leadership paradigms which contributes to social capital formation for addressing social problems’. Spiritual leadership capital is hereby argued to be a transformative spirituality that can enable an understanding and sustainable responses to poverty and other social problems. This is needed for Africa and particularly for the present day South Africa, seemingly a country with the best infrastructure in Africa; yet its poverty seems pronounced because the dregs of apartheid still lurk in the social fibre, where poor people blame rich people for their plight and vice versa. Bowers Du Toit’s view that ‘[m]ost congregations respond to poverty by providing relief and not empowerment’, re-echoes here. From a mixed-methods research, SLC is a theory recently advanced as a congregational development paradigm and a theology of poverty, which views public theology as an educative praxis that can respond to transformational needs in poverty-related contexts. The authors suggest that for a Church that is responsive to the plight of society, fresh empowerment approaches to address poverty are needed. (shrink)

Abstract: This essay explores recent trends and major issues related to gay and lesbian philosophy in ethics (including issues concerning the morality of homosexuality, the natural function of sex, and outing and coming out); religion (covering past and present debates about the status of homosexuality and how biblical and qur'anic passages have been interpreted by both sides of the debate); the law (especially a discussion of the debates surrounding sodomy laws, same-sex marriage and its impact on transsexuals, and whether the (...) law should be used to enforce morality); scientific research into the origins of homosexuality (including discussion of arguments against such research); and metaphysics (especially the question of whether homosexuality is socially constructed during particular times and in particular cultures, or whether sexual orientation is an essential trait cutting across times and cultures).

The purpose of this action research project was to examine the lived experience of university and community participants in ethical decision making in the setting of an interprofessional university-community partnership. The participatory framework for applied ethics presented by Prilleltensky, Rossiter, and Walsh-Bowers informed the research design. University and community participants in the 4-year-old partnership were interviewed about the ethical dilemmas faced in the partnership and ways of dealing with these dilemmas that often took place in the nexus of meeting (...) the community's and students' needs. An important aspect of making sound ethical decisions was the availability of multiple opportunities for discourse in an environment open to learning. (shrink)

We discuss the case against Factorism, which is the standard assumption in quantum mechanics that the labels of the $$\otimes$$ ⊗ -factor Hilbert-spaces in direct-product Hilbert-spaces of composite physical systems of similar particles refer to particles, either directly or descriptively. We distinguish different versions of Factorism and argue for their truth or falsehood. In particular, by introducing the concepts of snapshot Hilbert-space and Schrödinger-movie, we demonstrate that there are Hilbert-spaces and $$\otimes$$ ⊗ -factorisations where the labels do refer, even descriptively, (...) to similar particles, which renders them probabilistically absolutely discernible.

Exploring the connection between Bentham and Byron forged by the Greek struggle for independence, this book focuses on the activities of the London Greek Committee, supposedly founded by disciples of Jeremy Bentham, which mounted the expedition on which Lord Byron ultimately met his death in Greece. Rosen's penetrating study provides a new assessment of British philhellenism and examines for the first time the relationship between Bentham's theory of constitutional government and the emerging liberalism of the 1820s. Breaking new ground in (...) the history of political ideas and culture in the early nineteenth century, Rosen advances striking new interpretations based on recently published texts and manuscript sources of the development of constitutional theory from Locke and Montesquieu, the conflicting strands of liberalism in the 1820s, and the response in Britain to strong claims for national self-determination in the Mediterranean basin. He sets out to distinguish between Bentham's theory and the ideological context against which it is usually interpreted. (shrink)
