    The ethics review and the humanities and social sciences: disciplinary distinctions in ethics review processes.Jessica Carniel, Andrew Hickey, Kim Southey, Annette Brömdal, Lynda Crowley-Cyr, Douglas Eacersall, Will Farmer, Richard Gehrmann, Tanya Machin & Yosheen Pillay - 2023 - Research Ethics 19 (2):139-156.
    Ethics review processes are frequently perceived as extending from codes and protocols rooted in biomedical disciplines. As a result, many researchers in the humanities and social sciences (HASS) find these processes to be misaligned, if not outrightly obstructive to their research. This leads some scholars to advocate against HASS participation in institutional review processes as they currently stand, or in their entirety. While ethics review processes can present a challenge to HASS researchers, these are not insurmountable and, in fact, present (...)

    Beyond Criticism of Ethics Review Boards: Strategies for Engaging Research Communities and Enhancing Ethical Review Processes.Andrew Hickey, Samantha Davis, Will Farmer, Julianna Dawidowicz, Clint Moloney, Andrea Lamont-Mills, Jess Carniel, Yosheen Pillay, David Akenson, Annette Brömdal, Richard Gehrmann, Dean Mills, Tracy Kolbe-Alexander, Tanya Machin, Suzanne Reich, Kim Southey, Lynda Crowley-Cyr, Taiji Watanabe, Josh Davenport, Rohit Hirani, Helena King, Roshini Perera, Lucy Williams, Kurt Timmins, Michael Thompson, Douglas Eacersall & Jacinta Maxwell - 2022 - Journal of Academic Ethics 20 (4):549-567.
    A growing body of literature critical of ethics review boards has drawn attention to the processes used to determine the ethical merit of research. Citing criticism on the bureaucratic nature of ethics review processes, this literature provides a useful provocation for (re)considering how the ethics review might be enacted. Much of this criticism focuses on how ethics review boards _deliberate,_ with particular attention given to the lack of transparency and opportunities for researcher recourse that characterise ethics review processes. Centered specifically (...)

    COVID-19 Shows the Need to Make Church More Flexible.Jerry Pillay - 2020 - Transformation: An International Journal of Holistic Mission Studies 37 (4):266-275.
    The COVID-19 challenge is unprecedented. It has caused enormous trauma, disrupted economies, social life, mass transportation, work and employment, supply chains, leisure, sport, international relations, academic programmes; literally everything. Churches and religious communities have not been spared; they have been severely affected and, in all likelihood, permanently transformed by the pandemic. The pre-COVID-19 world is gone, replaced by a ‘new normal’. The new landscape calls for both resilience and adaptation, embracing new ways of doing things and of being church. Churches (...)

    On PAC and Bounded Substructures of a Stable Structure.Anand Pillay & Dominika Polkowska - 2006 - Journal of Symbolic Logic 71 (2):460 - 472.
    We introduce and study the notions of a PAC-substructure of a stable structure, and a bounded substructure of an arbitrary substructure, generalizing [10]. We give precise definitions and equivalences, saying what it means for properties such as PAC to be first order, study some examples (such as differentially closed fields) in detail, relate the material to generic automorphisms, and generalize a "descent theorem" for pseudo-algebraically closed fields to the stable context. We also point out that the elementary invariants of pseudo-algebraically (...)

    On Groups with Definable F_-Generics Definable in _P-Adically Closed Fields.Anand Pillay & Y. A. O. Ningyuan - 2023 - Journal of Symbolic Logic 88 (4):1334-1353.
    The aim of this paper is to develop the theory of groups definable in the p-adic field ${{\mathbb {Q}}_p}$, with “definable f-generics” in the sense of an ambient saturated elementary extension of ${{\mathbb {Q}}_p}$. We call such groups definable f-generic groups.So, by a “definable f-generic” or $dfg$ group we mean a definable group in a saturated model with a global f-generic type which is definable over a small model. In the present context the group is definable over ${{\mathbb {Q}}_p}$, and (...)

    Type-definability, compact lie groups, and o-minimality.Anand Pillay - 2004 - Journal of Mathematical Logic 4 (02):147-162.
    We study type-definable subgroups of small index in definable groups, and the structure on the quotient, in first order structures. We raise some conjectures in the case where the ambient structure is o-minimal. The gist is that in this o-minimal case, any definable group G should have a smallest type-definable subgroup of bounded index, and that the quotient, when equipped with the logic topology, should be a compact Lie group of the "right" dimension. I give positive answers to the conjectures (...)

    Theological Education and Missional Formation in the South African Context.Jerry Pillay - 2018 - Transformation: An International Journal of Holistic Mission Studies 35 (3):179-191.
    This article looks at theological education and missional formation in the South African context. It examines the understanding of theology and mission and connects it with theological education. It then proceeds to explore some of the essential elements that should constitute theological education in the South African context. The aim is to show that theological education in South Africa is in need of transformation.

    A note on groups definable in the p -adic field.Anand Pillay & Ningyuan Yao - 2019 - Archive for Mathematical Logic 58 (7-8):1029-1034.
    It is known Hrushovski and Pillay that a group G definable in the field \ of p-adic numbers is definably locally isomorphic to the group \\) of p-adic points of a algebraic group H over \. We observe here that if H is commutative then G is commutative-by-finite. This shows in particular that any one-dimensional group G definable in \ is commutative-by-finite. This result extends to groups definable in p-adically closed fields. We prove our results in the more general (...)

    Definability and definable groups in simple theories.Anand Pillay - 1998 - Journal of Symbolic Logic 63 (3):788-796.
    We continue the study of simple theories begun in [3] and [5]. We first find the right analogue of definability of types. We then develop the theory of generic types and stabilizers for groups definable in simple theories. The general ideology is that the role of formulas (or definability) in stable theories is replaced by partial types (or ∞-definability) in simple theories.

    Topological dynamics and definable groups.Anand Pillay - 2013 - Journal of Symbolic Logic 78 (2):657-666.
    We give a commentary on Newelski's suggestion or conjecture [8] that topological dynamics, in the sense of Ellis [3], applied to the action of a definable group $G(M)$ on its “external type space” $S_{G,\textit{ext}}(M)$, can explain, account for, or give rise to, the quotient $G/G^{00}$, at least for suitable groups in NIP theories. We give a positive answer for measure-stable (or $fsg$) groups in NIP theories. As part of our analysis we show the existence of “externally definable” generics of $G(M)$ (...)

    Commentary to ‘surrogate decision making in crisis’.Thillagavathie Pillay, Mona Noureldein, Manjit Kagla, Tracey Vanner & Deevena Chintala - forthcoming - Journal of Medical Ethics.
    As clinicians, this case1 raises both personal and professional challenges. A key issue is who carries legal parental responsibility for the difficult decisions that may be required around life-sustaining care in baby T. Medicolegally, we understand that the surrogate mother holds legal parental responsibility for baby T until this can be transferred to the intended parents.2 But this process can take many months to complete, after the birth of baby. As M is now critically ill and unable to engage in (...)

    Definability of types, and pairs of o-minimal structures.Anand Pillay - 1994 - Journal of Symbolic Logic 59 (4):1400-1409.
    Let T be a complete O-minimal theory in a language L. We first give an elementary proof of the result (due to Marker and Steinhorn) that all types over Dedekind complete models of T are definable. Let L * be L together with a unary predicate P. Let T * be the L * -theory of all pairs (N, M), where M is a Dedekind complete model of T and N is an |M| + -saturated elementary extension of N (and (...)

    Huldyrch Zwingli’s contribution to the Reformation.Jerry Pillay & Catherine McMillan - 2019 - HTS Theological Studies 75 (4):1-8.
    Huldyrch Zwingli, the first Swiss reformer in Zurich, made significant contributions to the 16th-century Reformation, yet he remains relatively unknown, if not forgotten. He is generally overshadowed by other reformers, such as Martin Luther and John Calvin. This article attempts to bring Zwingli to the surface by examining some of his contributions in Zurich which impacted the Reformation at large. This is especially significant because 2019 marks the 500th anniversary of Zwingli. The aim of the article is to provide an (...)

    Sex Differences in Depression and Anxiety Symptoms: Measurement Invariance, Prevalence, and Symptom Heterogeneity Among University Students in South Africa.N. Florence Tadi, Kaylene Pillay, Ufuoma P. Ejoke & Itumeleng P. Khumalo - 2022 - Frontiers in Psychology 13.
    Adequate measurement is an essential component of the assessment of mental health disorders and symptoms such as depression and anxiety. The present study investigated sex-specific differences in the Patient Health Questionnaire-9 and Generalized Anxiety Disorder-7. This comprehensive cross-sectional design study pursued four objectives: measurement invariance of PHQ-9 and GAD-7 between male and female; depression and anxiety prevalence differences; cross-sex differences in the relationship between depression and anxiety; and a comparison of symptom heterogeneity. A sample of 1966 students from South Africa (...)

    Given a lovely pair P ≺ M of models of a simple theory T, we study the structure whose universe is P and whose relations are the traces on P of definable (in ℒ with parameters from M) sets in M. We give a necessary and sufficient condition on T (which we call weak lowness) for this structure to have quantifier-elimination. We give an example of a non-weakly-low simple theory.

    Historical Theology at public universities matter.Jerry Pillay - 2017 - HTS Theological Studies 73 (1).
    South African universities are in the process of serious transformation and restructuring. The place of faculties of theology at universities has come under the spotlight resulting in the closure of several theological faculties or in the moving of theology to other faculties, mainly humanities or arts. Theology is under pressure and in the current academic environment, Church History, in its traditional form, has all but disappeared from South African universities. This article is an attempt to address the current situation. Whilst (...)

    The geometry of forking and groups of finite Morley rank.Anand Pillay - 1995 - Journal of Symbolic Logic 60 (4):1251-1259.
    The notion of CM-triviality was introduced by Hrushovski, who showed that his new strongly minimal sets have this property. Recently Baudisch has shown that his new ω 1 -categorical group has this property. Here we show that any group of finite Morley rank definable in a CM-trivial theory is nilpotent-by-finite, or equivalently no simple group of finite Morley rank can be definable in a CM-trivial theory.

    In this paper we introduce the notion of a first order topological structure, and consider various possible conditions on the complexity of the definable sets in such a structure, drawing several consequences thereof.Our aim is to develop, for a restricted class of unstable theories, results analogous to those for stable theories. The “material basis” for such an endeavor is the analogy between the field of real numbers and the field of complex numbers, the former being a “nicely behaved” unstable structure (...)

    Stable embeddedness and nip.Anand Pillay - 2011 - Journal of Symbolic Logic 76 (2):665 - 672.
    We give some sufficient conditions for a predicate P in a complete theory T to be "stably embedded". Let P be P with its "induced θ-definable structure". The conditions are that P (or rather its theory) is "rosy", P has NIP in T and that P is stably 1-embedded in T. This generalizes a recent result of Hasson and Onshuus [6] which deals with the case where P is o-minimal in T. Our proofs make use of the theory of strict (...)

    The significance of social justice and diakonia in the Reformed tradition.Jerry Pillay - 2022 - HTS Theological Studies 78 (4):12.
    The Reformed tradition, emerging in the 16th-century Reformation, consists of a variety of sources that often lead to complex and differing views about beliefs, doctrines and ethics. However, this tradition and theology have always stressed the significance of social justice and diakonia as important aspects of faith and ministry, even though its great sense of diversity has often nuanced and stressed different levels of understanding and engagement of social justice. This article aims to show that social justice and diakonia are (...)

It looks at how the church in selected periods in history, mainly in the reformation era, worked towards the transformation of society and communities. Extracting from these the author attempts to show how this can be applied to the church in the South African context. Further, the author explores the changing dynamics and characteristics of being church today and establishes that it is not so much (...)

    Many Christians feel quite disillusioned and disappointed with the church in South Africa today because they assume that the church, in particular the South African Council of Churches, is not playing an adequate prophetic role in building the democratic South Africa since 1994. This article traces the role and contributions of the SACC and other ecumenical organisations to the building of a democratic South Africa. It establishes that whilst the SACC had lost its focus and vision and has an ecumenical (...)
