Systematic review of ethical issues in perinatal mental health research.Mickie de Wet,Susan Hannon,Kathleen Hannon,Anna Axelin,Susanne Uusitalo,Irena Bartels,Jessica Eustace-Cook,Ramón Escuriet &Deirdre Daly -2023 -Nursing Ethics 30 (4):482-499.detailsBackground Maternal mental health during the peripartum period is critically important to the wellbeing of mothers and their infants. Numerous studies and clinical trials have focused on various aspects of interventions and treatments for perinatal mental health from the perspective of researchers and medical health professionals. However, less is known about women’s experiences of participating in perinatal mental health research, and the ethical issues that arise. Aim To systematically review the literature on the ethical issues that emerge from pregnant and/or (...) postpartum women’s experiences of taking part in perinatal mental health-related research. Methods Systematic review of nine bibliographic databases, from inception to July 2021. Qualitative, quantitative and mixed method studies were included if they reported on ethical issues experienced by perinatal women. Research ethical issues encompassed any issue relating to women’s experiences of being offered study information, recruitment, consent, retention and respect for autonomy. Titles, abstracts and full text screening, appraisal of the methodological quality of included studies, and data extraction, were conducted independently by two reviewers. Ethical considerations Ethical approval was not required for this systematic review. Findings A total of 9830 unique citations was retrieved. Six studies met the inclusion criteria. Studies were clinically and methodologically heterogenous, and only one was purposively designed to explore women’s experiences. The key finding was the establishment of trust between the researcher and participant in all stages of the research process. Findings are presented according to recruitment and consent processes, participation and retention, and study follow-up and completion. Conclusion The establishment of trust between the researcher and perinatal women leads to a dynamic with research ethical implications relevant to all stages of perinatal mental health-related research. Further research on the research ethical issues experienced by perinatal women is required because of the limited literature. (shrink)
John Chrysostom on Manichaeism.Chris L. de Wet -2019 -HTS Theological Studies 75 (1):6.detailsThis article examines John Chrysostom’s (ca. 349–407 CE) statements about Manichaeism. The study enquires regarding the extent of Chrysostom’s knowledge of Manichaean beliefs and practices, and whether he possibly had contact with Manichaeans. The study is not so much interested in determining how accurately or inaccurately Chrysostom understands and characterises Manichaeism, although at some points the analysis does venture into some of these issues. In the first instance, Chrysostom’s views about Manichaean theology and, especially, Christology are delineated. Proceeding from the (...) negative evaluation of the material cosmos in Manichaeism, the study then looks at Chrysostom’s critique of Manichaean views of the body, especially as it relates to freedom of choice. Chrysostom’s accusations of Manichaean practices, namely, starving as salvation and the accusation of castration, are also examined. Finally, Chrysostom’s response to the Manichaean rejection of a corporeal resurrection is analysed, after which some conclusions are drawn. (shrink)

The Book of Tobit in early Christianity: Greek and Latin interpretations from the 2nd to the 5th century CE.Chris L. de Wet -2020 -HTS Theological Studies 76 (4):13.detailsThis article examines the early Christian reception of the apocryphal book Tobit, focusing on Greek and Latin Christian interpretations from the 2nd to the 5th century CE. The study asks: how did early Christians read Tobit and for what purposes? The article provides an overview of how and why Tobit ended up in the Christian Bible, whether canonical or apocryphal. It then examines how the figures of Tobit and his son, Tobias, function as a moral exemplum in early Christianity, especially (...) related to almsgiving and financial management, burials and the care of the dead, marriage and parenthood, prayer, the suffering and endurance of Tobit, and the role of Tobit in the Christian understanding of angels. The article demonstrates that Tobit had a rich and diverse reception in early Christian biblical interpretation, especially in the Latin church of the West. Contribution: This article investigates the historical reception of the apocryphal Book of Tobit in early Christian thought. The focus is especially on the varieties of thought regarding Tobit. The article provides an overview of how and why Tobit ended up in the Christian Bible, whether canonical or apocryphal. It then examines how the figures of Tobit and his son, Tobias, function as moral exempla. (shrink)

Rahab the harlot in Severian of Gabala’s De paenitentia et compunctione (de Rahab historia): Paradox, anti-Judaism and the early Christian invention of the penitent prostitute.Chris L. de Wet -2020 -HTS Theological Studies 76 (3):7.detailsThis article examines the 4th-century CE interpretation of the story of Rahab the Harlot by Severian of Gabala, in his homily, De paenitentia et compunctione (CPG 4186). In this article, a close and critical reading of Severian’s references to the story of Rahab in De paenitentia et compunctione (with some comparative reference to other works of Severian, and also of John Chrysostom and Pseudo-Chrysostom) is provided. It is asked, ‘how and why could a treacherous harlot, a prostitute, who was considered (...) to be the epitome of vice in early Christian moral deliberations, function as an exemplum for Severian?’ The article firstly asks how Severian deals with the problematic and paradoxical aspects of Rahab, namely, the fact that she was a prostitute and also a liar. Then, it illustrates how Severian transforms Rahab into a Christian heroine and how he deploys these qualities of the transformed Rahab in a potent anti-Judaistic rhetoric. This study is finally concluded with a somewhat broader delineation of the importance of Rahab in the development of a curious Christian cultural and moral trope, namely, the penitent prostitute. Such a study of Rahab is significant not only in that it expands our understanding of the history of women and gender dynamics in early Christianity, but it also elucidates the complex and strategic discursive moves employed by male Christian authors to deal with the seemingly ‘bad girls’ of scripture. Contribution: This article investigates the historical reception of the story of Rahab (Jos 2) in a little-known homily by Severian of Gabala. The focus is how Severian interprets the story and the paradoxical figure that is Rahab, with reference to its use as an anti-Judaistic trope, and its role in the shaping of the cultural phenomenon that is the penitent prostitute in early Christian thought.

‘The barbarians themselves are offended by our vices’: Slavery, sexual vice and shame in Salvian of Marseilles’ De gubernatione Dei.Chris L. de Wet -2019 -HTS Theological Studies 75 (3):8.detailsThe purpose of this article is to examine Salvian of Marseilles’ (ca. 400–490 CE) invective in De gubernatione Dei against his Christian audience pertaining to their sexual roles and behaviour as slaveholders. It is argued that rather than considering the oppressive practice of slavery in itself as a reason for moral rebuke and divine punishment, Salvian highlights the social shame that arose from the sexual vices Christian slaveholders committed with their slaves. Salvian forwards three accusations against his opponents that concern (...) slavery and sexual vice. Firstly, he asserts that Christian slaveholders have no self-control. Secondly, the polyamorous relationships slaveholders have with numerous slaves resemble shameful and adulterous unions, namely concubinage and even polygamy. Thirdly, Roman-Christian slaveholders behave in a worse manner than barbarians (i.e. the argument of ethnicity). Each of these accusations is examined in detail in the study. (shrink)

(1 other version)Contemporary prophetic preaching theory in the United States of America and South Africa: A comparative study through the lens of shared Reformation roots.Leonora Tubbs Tisdale &Friedrich W. de Wet -2014 -HTS Theological Studies 70 (2):01-08.detailsIn this article two homileticians - one from the United States of America (USA) and one from South Africa (SA) - enter into a dialog regarding how the task of prophetic preaching today might be revived, reframed and redefined in light of the Reformation principle of the viva vox Evangelii [living voice of the gospel]. Each author begins by summarising four contemporary approaches to prophetic preaching set forth by Reformed and Lutheran homiletical scholars in their respective contexts. Then each addresses (...) the questions: Where do I particularly see Reformation themes and emphases at work in the work of these homileticians? And how might those Reformation emphases continue to challenge and reframe preaching practices today? Finally, each gives initial reflections on how a comparison between the perspectives deepens and expands his or her understanding of prophetic preaching and its role in church and society. (shrink)
On the topology of nuclear manifolds.J. A. de Wet -1981 -Foundations of Physics 11 (1-2):155-169.detailsIn earlier work, representations ofr nucleons were constructed by taking therth Kronecker product of self-representations of the complete homogeneous Lorentz groupL 0 , where these were in the form of a four-component Dirac spinor with components corresponding to the internal symmetries of spin, parity, and charge. When permutations that include every possible exchange of spin, charge, and coordinate, are factored out, the4 F coordinates of flat Minskowski space are contracted by an isometry φ such that energy levels correspond to troughs (...) or saddle points in the new nuclear manifoldM. This is a symmetric space, and using the critical point theory of Morse for the neighborhood of an energy level, it is found that the symmetry σ associated with φ separatesM into just the sets of rotational and vibrational levels. Furthermore, by employing only one parameter, corresponding to the range of energies encountered, good agreement is found with the experimental levels and state labels of 10 B, 10 Be, 10 C, 10 C, and 10 O. The supermultiplet theory of Wigner is a necessary condition for the existence of the states. (shrink)
Naming and nurturing reality from a heart renewed by grace.Fritz W. De Wet -2015 -HTS Theological Studies 71 (2):01-08.detailsThis contribution investigates the unbearable tension between the homiletical act of naming reality on the one hand, and neglecting this same reality on the other hand, thereby causing it to return to an ignored, unchallenged and degenerated state. The author focuses on tension fields that are generated when preachers embark on the activity of naming realities in their proximate contexts and how they position, withdraw or distance themselves in a certain way when problematic elements are opened up by the act (...) of naming. By means of a theological reflection on the renewal of the heart by God's act of grace in Christ, the author attempts to identify key markers for a homiletic theory that will be able to link the act of naming reality with the act of nurturing this named reality.

Nuclear structure on a Grassmann manifold.J. A. de Wet -1987 -Foundations of Physics 17 (10):993-1018.detailsProducts of particlelike representations of the homogeneous Lorentz group are used to construct the degrees of spin angular momentum of a composite system of protons and neutrons. If a canonical labeling system is adopted for each state, a shell structure emerges. Furthermore the use of the Dirac ring ensures that the spin is characterized by half-angles in accord with the neutron-rotation experiment. It is possible to construct a Clebsch-Gordan decomposition to reduce a state of complex angular momentum into simpler states (...) which can be identified with α and β particles, multipole operators, etc. Finally, ground-state energy levels are calculated for all the even-even nuclei by using a differentiable manifold that is spin-graded and gauge-invariant by construction. It is shown that this manifold is Grassmann. (shrink)
On nuclear energy levels and elementary particles.J. A. de Wet -1982 -Foundations of Physics 12 (3):285-300.detailsConsidering only exchange forces, the binding energies and excited states of nuclei up to 24 Mg are predicted to within charge independence, and there is no reason why the model should not be extended to cover all of the elements. A comparison of theory with experiment shows that the energy of one exchange is 2.56 MeV. Moreover, there is an attractive well of depth 30 MeV, corresponding to the helium nucleus, before exchange forces become operative. A possible explanation of the (...) origin of mesons is also presented. (shrink)
Particular divine action: a challenge to intellectual integrity in a post-Christian age.Brenda de Wet -2008 -South African Journal of Philosophy 27 (2):91-103.detailsThe fact that certain configurations of problems and the philosophical antinomies, paradoxes and confusions they contain regularly return in the history of the rational exposition of these problems points to more than the limitations of human reason and the inexhaustibility of the subject matter; it is indicative of a structural problem . If we agree that integrity is defined as the quality of being unimpaired based on unity or wholeness, then holding beliefs based on theories compromised by structural problems jeopardises (...) one’s intellectual integrity. The Christian notion of particular divine action founders on more than one structural problem. On the one hand, divine action is held to be constitutive of the Christian faith. On the other hand, it is held to be inconceivable , improbable , impossible , unnecessary , and indefensible by the way many interpret current scientific, philosophical and theological theories. Together, these objections assert that divine action is implausible. This paper outlines five objections to particular divine action that poses a challenge to intellectual integrity. In doing so, the minimum requirements for a rationally justifiable theory of divine action is delineated. (shrink)
The practice of everyday death: Thanatology and self-fashioning in John Chrysostom’s thirteenth homily on Romans.Chris L. De Wet -2015 -HTS Theological Studies 71 (1).detailsThe purpose of this article is to investigate the relationship between the discourse of death, or thanatology, and self-fashioning, in John Chrysostom’s thirteenth homily In epistulam ad Romanos. The study argues that thanatology became a very important feature in the care of the self in Chrysostom’s thought. The central aim here is to demonstrate the multi-directional flow of death, as a corporeal discourse, between the realms of theology, ethics, and physiology. Firstly, the article investigates the link between the theological concepts (...) of sin and death. Secondly, the study argues that death also becomes a highly paradoxical discourse when it enters the realm of Chrysostomic virtue-ethics, where the mortification of excessive passion leads to life, while ‘living’ in passion only results in death on every level of existence – death as a discourse therefore becomes interiorised, a process functioning as a subset of a more extensive biologisation of the spiritual life-cycle. Finally, Chrysostom also utilises death in a very physiological way, especially in his comments on the relationship between sin and the passions, and one’s physical health and appearance. (shrink)

Canon, sex and gender in Theodoret of Cyrus’s exposition of LXX Ruth.Chris L. de Wet -2022 -HTS Theological Studies 78 (1):7.detailsThe purpose of this article is to examine Theodoret of Cyrus’s (ca. 393–ca. 457 CE) exposition of LXX Ruth, as found in his Questions on the Octateuch. At the centre of this analysis lies the question of what an early Christian author like Theodoret, who lives in a context where asceticism and sexual renunciation were quite popular (i.e. Christian Syria), does with a complicated text like Ruth, which contains so many explicit nuances about sex, procreation and marriage, as well as (...) various gendered complexities. The article starts by examining briefly the canonisation history of Ruth in early Christianity and some of the main interpretative trends in readings of Ruth by other Christian authors. Then, Theodoret’s interpretation of Ruth is examined, focusing specifically on his Questions on Ruth. The purpose of Ruth as scripture, according to Theodoret, is first delineated, after which Theodoret’s approach to sex and gender in LXX Ruth is examined.Contribution: This article argues that Theodoret transforms the story of Ruth into one that aligns with the moral-philosophical discourse related to sex, marriage and gender of his own time. Theodoret restructures Ruth androcentrically by placing Boaz, the masculine and virtuous male father-figure, at the centre of the story, while at the same time stripping Ruth of any possible agency she might have as a would-be temptress.

The ontic status of the laws of nature.Brenda De Wet -2007 -South African Journal of Philosophy 26 (2):122-132.detailsWhile most of us have accepted that our theories are human constructs and approximations of the truth, many of us still think of ‘natural laws ’ as things that exist ‘out there’, and that the work of science is thus the discovery or uncovering of these laws and their expression in mathematical formulae. This notion has serious implications for the science-theology debate. This article challenges the notion that ‘natural laws ’ adequately describe or prescribe nature. It argues that law statements (...) are idealised abstractions that only weakly explain and describe reality, and that mathematics, the ‘language’ of science, is not immutable. It challenges the prescriptive nature of law statements by arguing that we are limited beings who cannot know reality in itself. Our meta-scientific commitments co-determine what and how we think of laws, and the complexity of reality defies human analysis and explanations. Far from having ontic status or being complete and accurate descriptions of reality, natural laws at best mimic the key structures and relationships of the reality they refer to. We would do better to think of reality as an open system of inseparable, interacting and ever-moving components, with the observer an integral part of the system. It is an illusion to believe that these incredibly rich representations of the phenomena are unconstructed isomorphisms we merely discover in the real world. Instead they are constructed – painstakingly so – and there is no evidence that they are isomorphic with structures in the real world.

The Importance of Ethical Appraisal in Social Science Research: Reviewing a Faculty of Humanities' Research Ethics Committee. [REVIEW]Katinka De Wet -2010 -Journal of Academic Ethics 8 (4):301-314.detailsResearch Ethics Committees or Institutional Review Boards are rapidly becoming indispensable mechanisms in the overall workings of university institutions. In fact, the ethical dimension is an important aspect of research governance processes present in institutions of higher learning. However, it is often deemed that research in the social sciences do not require ethical appraisal or clearance, because of the alleged absence of harm in conducting such research. This is an erroneous and dangerous assumption given that research in social sciences poses (...) various and complex dilemmas related to ethics. The article aims to gauge the importance of ethical appraisal at a particular institution of higher learning’s Faculty of Humanities. This is done by scrutinising its defunct REC, and the views that Heads of Departments of the Faculty have of ethics in research and the need for ethical appraisal by this REC. Finally, some suggestions are made to proceed to review and restructure the current REC with the ultimate objective to make it functional again. It was found that the development and discussion around ethics in research and ethical appraisal are part of a much needed thrust to sensitise the entire Faculty and the institution on the widespread beneficial repercussions of ethical awareness in research and beyond.

Testing a Modified Version of Schwartz’s Portrait Values Questionnaire to Measure Organizational Values in a University Context.Daniela Wetzelhütter,Chigozie Nnebedum,Jacques De Wet &Johann Bacher -2020 -Journal of Human Values 26 (3):209-227.detailsSchwartz developed his Theory of Basic Human Values and corresponding instruments, the portrait values questionnaire (PVQ) and the Schwartz values survey (SVS), in order to measure personal values. He uses these instruments (in a slightly modified form) in conjunction with his Theory of Cultural Value Orientations to measure cultural or societal values. His theoretical work is also used in studying organizational values; however, none of these instruments seem suitable to compare personal and perceived organizational values. If the PVQ is widely (...) used to measure personal values, and we need commensurate measures of the person and organization for comparative analysis, then can we not minimally adjust the PVQ to measure organizational values? In this article we discuss the testing of one such adjusted PVQ used for gauging universities’ organizational values. We developed the PVQ-uni to measure university values as perceived by students. We collected data from sociology departments at two universities, one in Austria ( n = 133) and one Nigeria ( n = 156). We then tested the reliability and the validity of the new instrument. Based on the data collected, we found that the PVQ-uni is a reliable and valid instrument; however, further refinements are needed for the instrument to be used successfully in Africa. (shrink)

Pseudo-John Chrysostom’s Homily On Susanna (CPG 4567) (Daniel 13 LXX): Masculinity, psychic typology and the construction of early Christian salvation history. [REVIEW]Chris L. de Wet -2021 -HTS Theological Studies 77 (4):6.detailsThis article investigates a short Greek Christian homily, from the 4th century CE, by an anonymous Cappadocian preacher on the narrative of Susanna in Dan 13 LXX. The homily is simply titled, On Susanna (CPG 4567), and has been erroneously transmitted as a work of John Chrysostom. The purpose of this article is to examine more closely the construction of Susanna in the homily, with specific reference to the use of masculinity, psychic typology and finally, the construction of early Christian (...) salvation history. After addressing, in brief, some matters of canonicity, a close reading of On Susanna is given. It is demonstrated that the Cappadocian strategically constructs Susanna like a virginal Christian martyr and ascetic, with the aim of highlighting her masculine steadfastness and dominance in her contest ( agōn ) against the elders. A significant second move that is made in the homily is to position the masculine Susanna as a type for the soul of the individual, which should also be guarded against the onslaught of sin and the passions. Contribution: This Christian reconstruction of Susanna brings the subjectivity of the individual listener in the audience, and the character of Susanna, in close proximity to one another. In effect, by internalising the narrative of Susanna into the realm of the soul, the anonymous Cappadocian preacher is able to utilise a layered biblical salvation history that incorporates not only narratives from the Bible, but also the audience member’s own individual narrative and struggles into the grander scheme of salvation history.
