In this paper we discuss ethical implications of the use of mobile phone apps in the control of the COVID-19 pandemic. Contact tracing is a well-established feature of public health practice during infectious disease outbreaks and epidemics. However, the high proportion of pre-symptomatic transmission in COVID-19 means that standard contact tracing methods are too slow to stop the progression of infection through the population. To address this problem, many countries around the world have deployed or are developing mobile phone apps (...) capable of supporting instantaneous contact tracing. Informed by the on-going mapping of ‘proximity events’ these apps are intended both to inform public health policy and to provide alerts to individuals who have been in contact with a person with the infection. The proposed use of mobile phone data for ‘intelligent physical distancing’ in such contexts raises a number of important ethical questions. In our paper, we outline some ethical considerations that need to be addressed in any deployment of this kind of approach as part of a multidimensional public health response. We also, briefly, explore the implications for its use in future infectious disease outbreaks. (shrink)

The transcriptional co‐activators YAP (or YAP1) and TAZ (or WWTR1) are frequently activated during the growth and progression of many solid tumors, including lung, colorectal, breast, pancreatic, and liver carcinomas as well as melanoma and glioma. YAP/TAZ bind to TEAD‐family co‐activators to drive cancer cell survival, proliferation, invasive migration, and metastasis. YAP/TAZ activation may also confer resistance to chemotherapy, radiotherapy, or immunotherapy. YAP‐TEAD cooperates with the RAS‐induced AP‐1 (FOS/JUN) transcription factor to drive tumor growth and cooperates with MRTF‐SRF to promote (...) activation of cancer‐associated fibroblasts, matrix stiffening, and metastasis. The key upstream repressor of YAP/TAZ activation is the Hippo (MST1/2‐LATS1/2) pathway and the key upstream activators are mechanically induced Integrin‐SRC and E‐cadherin‐AJUBA/TRIP6/LIMD1, growth factor induced PI3K‐AKT, and inflammation‐induced G‐protein coupled receptor (GPCR) signals, all of which antagonize the Hippo pathway. In this review, strategies to target YAP/TAZ activity in cancer are discussed along with the prospects for synergy with established pillars of cancer therapy. (shrink)

We uncover a largely unnoticed and unaddressed problem in conservation research: arguments built within studies are sometimes defective in more fundamental and specific ways than appreciated, because they misrelate values and empirical matters. We call this the unraveled rope problem because just as strands of rope must be properly and intricately wound with each other so the rope supports its load, empirical aspects and value aspects of an argument must be related intricately and properly if the argument is to objectively (...) support its conclusion. By characterizing this problem with precision, our study differs from but complements existing studies of value issues in conservation science, in two ways. First, it focuses on key relationships between empirical issues and value issues, relations that have sometimes been obscured by focusing on these issues more independently of each other. Second, it focuses on these relationships within arguments and deploys a method of argument analysis and evaluation honed in other fields but under-utilized in conservation science. By combining our study's novel features, we detail six families of argument defect that exemplify the unraveled rope problem within existing literature. These defects sometimes manifest within basic research stages, rather than just in more applied downstream stages where roles for values are already obvious to many. As scientific reasoning and communication become increasingly important for addressing society's greatest environmental challenges, overcoming the unraveled rope problem will be essential to the success and integrity of conservation research. Therefore, we also outline potential solutions, preventative measures, and useful further work for conservation researchers. (shrink)

Several lines of evidence have underscored the remarkable neuroplasticity of the primate sensorimotor cortex, characterizing these cortical areas as dynamic constructs that are modelled in a use-dependent manner by behaviourally significant experiences. Their plasticity likely provides a neural substrate that may contribute to the dynamic systems paradigm argued by Shanker & King (S&K) as crucial for development of communication skills.

This commentary focusses on MacNeilage's arguments and evidence that the development of cerebral cortical controls over cyclic ingestive movements has provided substrates for the evolution of speech production. It outlines evidence from experimental approaches using cortical stimulation, inactivation, and single neuron recording in primates that lateral frontal cortical regions are indeed crucial for the generation and guidance of cyclic orofacial movements.

Working through Esme Johnson’s case brings to light many of the elements that make for a rich and impactful clinical ethics consultation. The health and well-being of a young person, whether a fami...

Understanding spoken words involves a rapid mapping from speech to conceptual representations. One distributed feature-based conceptual account assumes that the statistical characteristics of concepts’ features—the number of concepts they occur in and likelihood of co-occurrence —determine conceptual activation. To test these claims, we investigated the role of distinctiveness/sharedness and correlational strength in speech-to-meaning mapping, using a lexical decision task and computational simulations. Responses were faster for concepts with higher sharedness, suggesting that shared features are facilitatory in tasks like lexical decision (...) that require access to them. Correlational strength facilitated responses for slower participants, suggesting a time-sensitive co-occurrence-driven settling mechanism. The computational simulation showed similar effects, with early effects of shared features and later effects of correlational strength. These results support a general-to-specific account of conceptual processing, whereby early activation of shared features is followed by the gradual emergence of a specific target representation.

Alternative food networks are emerging in opposition to industrial food systems, but are criticized as being exclusive, since customers’ ability to patronize these market spaces is premised upon their ability to pay higher prices for what are considered the healthiest, freshest foods. In response, there is growing interest in widening the demographic profile given access to these alternative foods. This research asks: what barriers do alternative food businesses face in providing access and inclusion for low income consumers? Surveys and interviews (...) with 45 alternative food businesses in British Columbia, Canada uncovered five key barriers. The findings indicate that the barriers are symptomatic of structural issues in the Canadian food and social welfare systems. Although opportunities exist for business operators to widen access for low income shoppers, these alone cannot meaningfully ameliorate food-access inequality. Rather, these barriers underscore issues of income-disparity, poverty, and food-access inequality more broadly, and require structural and societal change to rectify. (shrink)

Clear guidelines addressing the ethically appropriate use of anti-infectives in the setting of hospice care do not exist. There is lack of understanding about key treatment decisions related to infection treatment for patients who are eligible for hospice care. Ethical concerns about anti-infective use at the end of life include: (1) delaying transition to hospice, (2) prolonging a dying process, (3) prescribing regimens incongruent with a short life expectancy and goals of care, (4) increasing the reservoir of potential resistant pathogens, (...) (5) placing unreasonable costs on a capitated hospice system. Although anti-infectives are thought to be relatively safe, they can place a burden on patients and be inconsistent to particular care plans. The current complex, and at times fragmented, medical care often fails to address these issues in decision-making. In many ways, the ethics governing the end of life decisions related to dialysis, hydration/nutrition, and hypercalcemia parallel those of anti-infectives. In this article we articulate important elements in ethical decision-making in the application of anti-infectives for patients who are eligible for hospice care, and we point to the need for prospective studies to help refine particular guidelines in these cases.

Ephesians 1:14 and 1:22, 23 as a scriptural maximum-minimum for ecclesiology. Against the background of a membership decline in mainstream churches in South Africa and abroad, and conscious of the theological debate in which a missional ecclesiology is presented as at least part of the modern-day solution to the problem, this article points in the direction of a Christological ecclesiology as an important ecclesiological point of departure. The article gives an exegetical outline of Ephesians 1:14 and 1:22, 23 as a (...) critical maximum-minimum for a Christological ecclesiology and as a means of making missional ecclesiology more acceptable.

A tolerant treatment of church order and the law of usance: This article discusses the recent decline of church polity in the Netherdutch Reformed Church which is obvious in different areas of the Church with special reference to the liturgy practised in sermons of some congregations. This decline is also observed in other churches in South Africa and abroad. The article is a reaction to the reason for this situation and indicates that it should not be found in a collegialistic (...) concept of church, but rather due to congregationalism or independentism in modern form. The article’s viewpoint is that the above-mentioned church polity decline is a result of the fact that church order is not valued as an order with a Scriptural and therefore an ecclesiological basis.

Central sensitization and related neurochemical mechanisms are also induced in V nociceptive pathways after craniofacial injury or inflammation. Their characteristics raise additional possibilities that may explain some of the phenomena outlined by coderre & katz, dickenson, and wiesenfeld-hallin et al. They also underscore the need for therapeutic approaches to reduce nociceptive inputs to the CNS or their neuroplastic effects which can potentially enhance post-traumatic pain.

Organizational ethics programs often are created to address tensions in organizational values that have been identified through repeated clinical ethics consultation requests. Clinical ethicists possess some core competencies that are suitable for the leadership of high-quality organizational ethics programs, but they may need to develop new skills to build these programs, such as familiarity with healthcare delivery science, healthcare financing, and quality improvement methodology. To this end, we suggest that clinical ethicists build organizational ethics programs incrementally and via quality improvement (...) projects undertaken in collaboration with senior clinical leaders. Organizational ethics programs often differ from clinical ethics programs in their membership and processes, and likely will require ethicists to forge new partnerships with a wide array of organizational leaders. With attention to the ways that organizational ethics programs differ from clinical ethics programs, and investment in quality improvement methodology and formal institutional needs assessments, clinical ethics leaders can position an organizational ethics program to advocate effectively for visible and compelling alignment of leadership decision making with the values of the organization.

The ecclesiastical debate at the 73 General Church Assembly of the Dutch Reformed Church of Africa. Reformed churches emerged from the Reformation which commenced in the 16th century because of the input of well-known reformers such as Martin Luther (1483–1546) and John Calvin (1509–1564). Reformed churches are founded on a certain system of church polity known as presbyterial-synodal. This church orderly viewpoint amounts to the fact that it is a church where Jesus Christ is the sole ruler of the church, (...) transforming all meetings of offices of the church to operate on the same horizontal level with Jesus Christ as the only and sufficient authority in the church. This means that such a church is trying to be church of the Word and should take good care to maintain this critical principal position during meetings, as will eventually be reflected in synodal decisions taken. Contribution: This article takes a critical look at points of discussion submitted to the meeting, especially those with church orderly implications. Critically spoken, it means that decisions tabled at such meetings should be in the prolongment of the churches’ decision to be church of the Word, and therefore presbyterial-synodal. It is therefore also a contribution to church polity as such. (shrink)

This article believes church polity is critically important, especially in recent times where an appeal is quite easily made to the courts of the political dispensation. The article believes the scriptural viewpoint that Jesus Christ is head of the church plays a substantial role in the modern-day church, which should be kept in mind regardless. Reference is made to court cases in the past and the conclusion is that church polity is relevant because it is a scriptural necessity.

This article gives a short reflection on the background and origin of the social-scientific model change agent in relation to change agency, a relationship that causes an alternate state of consciousness for the change agent. Arguing from the seven-point explanation of Malina and Pilch of how a change agent operates, this article applies the model to the letter to the Ephesians. The conclusion is that this social-scientific model is helpful for the recent church to realise how narrow the relation is (...) between Jesus Christ and the church, in view of the future of the church as a future in Christ. A choice is made to find alternate words in the Afrikaans language suitable for the theological debate, namely opdraggewer [change agency], meningsvormer [change agent] and alternatiewe staat van bewussyn [alternate state of consciousness].

The sentence 'to rule with him in the heavenly world' as example of an eschatological highlight in the letter to the Ephesians: The viewpoint in this article is that the above-mentioned statement in the letter to the Ephesians can be seen as an eschatological sentence of extraordinary value. In view of different eschatological viewpoints from the past, it can be stated that this sentence is an example of eschatology not only for the future, but also for the present. It is (...) understandable that there is a close link between eschatology and mission. The meaning of theosis, a concept from the Eastern churches' theological debate, underlines the need for a present eschatological consciousness that has significance for the future of church and faith. Believers can in this way escape from the destructive lust that is in the world, and may become partakers of the divine nature. (shrink)

This article discusses the meaning of ecclesiology and church polity as such, in relation to each other, but also in connection to church order which lies in the elongation of both. From a reformed perspective, it is indicated that the ecclesiology of the Netherdutch Reformed Church over the last fifty to hundred years, centred round the viewpoint of the Church as a volkskerk, in conjunction with the church orderly, of the Kerkwet till 1997. The author is of the opinion that (...) the above-mentioned viewpoint limited the church to be a true church of the Word. (shrink)
