Consensual Understanding Research Articles

Baptist and Catholic? Tradition and Authority in the Baptist Theology of Stephen R. Holmes

Abstract This article begins by analysing the principles at the heart of Stephen R. Holmes’ vision of Baptist theology and ecclesiology. It then examines Holmes’ work on the authority of theological Tradition. It is demonstrated that Holmes argues for a pneumatologically rooted and consensual understanding of Tradition that locates its authority in the testimony of the whole church to the voice and will of the Spirit interpreting the texts he inspired. In the final third of the argument, these two areas of Holmes’ work are brought into dialogue to generate an authentically Baptist conception of the authority of Tradition to bind the local church. It is suggested that this can help Baptists and others holding to some form of congregational church government resolve issues in their commitment to the catholicity and unity of the Church, provide a more secure ground for theological discernment, and enable more fruitful ecumenical dialogue.

Generative Artificial Intelligence Systems and the Challenges in Latin American Education

This article examines the transformative role of Generative Artificial Intelligence (GAI) in education, exploring diverse disciplines such as engineering, medicine, programming, and information systems. GAI emerges as a revolutionary force, promising to fundamentally change educational practices. The PRISMA 2020 methodology (Page et al., 2021) was used to evaluate the relevant scientific literature. The systematic review identified research that applied specific criteria in the analysis of IAG in education. The selected papers covered a variety of disciplines, providing a comprehensive view of the impact of IAG in education. The results show a diversity of approaches and institutional responses to IAG in education. From significant changes in teaching practices to the identification of specific opportunities in disciplines such as computer science and engineering, GAI stands out as a catalyst for transformation. The adaptation of tertiary education, the need for specific skills to work with GAI, and ethical responses emerge as key themes. It focuses on the need for a deeper and more consensual understanding of the role of GAI in education. Concrete research-supported opportunities are highlighted, but ethical limitations and concerns are also underscored. Collaboration, reflection, and adaptation to open educational practices are proposed as approaches to address the challenges and fully exploit the benefits of IAG in education. This comprehensive analysis contributes to understanding the current and future landscape of GAI in education, providing valuable guidelines for educators, institutions, and educational technology developers.

Transgressive Knowing

This issue's In-Dialogue represents the intentional epitomization of many conversations the Editorial Team has been having since JASC’s inception around what we mean by 'transformative'. As convenors of the dialogue Oliver Koenig and Megan Seneque invited a small group of individuals who, in their ongoing work, have been deeply immersed in exploring research and praxis paradigms that respond ethically, critically, and creatively to the intersecting crises of our time. Together, the group set out to explore the integrity of 'research' and 'practice', their critical entanglement and co-dependence, and the nature of practices that enable worlds to be created in certain ways. Rather than attempting to arrive at a consensual understanding, the dialogue that unfolds can be seen as a mirror of the world-making practice(s) that are characteristic of transformative research

Learning from stress: Transforming trauma into sustainable risk reduction

This study explores the collective learning process that evolved in the cities, towns, and districts damaged in the February 6, 2023, Kahramanmaraş earthquakes in Türkiye. Employing a multi-methods approach and a dataset comprising a review of relevant documents, semi-structured interviews, and field observations, we examine four fundamental stages of collective learning – knowledge acquisition, information distribution, interpretation, and organizational memory – in assessing the learning process in communities exposed to the devastation and trauma of the earthquakes. The study highlights the importance of adaptation, change, and collective growth as communities struggle to cope with the demands incurred by the disaster, and identifies factors that inhibit such growth in practice. In the aftermath of the Kahramanmaraş earthquakes, individuals and organizations sought to adapt their existing knowledge and practices to meet the challenges posed by recovery from this disaster and to build a consensual understanding of changes needed to achieve sustainable reduction of continuing seismic risk. The study underscores the vital Importance of timely and accurate Information In enabling Individuals and organizations to make informed decisions during and after the chaos engendered by the earthquakes. It highlights the pivotal role of technology in bridging communication gaps and facilitating the flow of critical information. The study concludes by identifying inaccurate information as the most harmful characteristic inhibiting collective learning, and by emphasizing the importance of aligning collective learning processes simultaneously among diverse groups within the community and across jurisdictional levels of operation. This study offers valuable insights into how to translate collective learning from traumatic events into sustained measures to reduce the risk of future disasters, going beyond resilience to achieve sustainable risk reduction. By understanding the factors that drive collective learning and the challenges that can arise, policymakers and practitioners can develop more effective strategies for supporting collective learning in the aftermath of extreme events.

Advanced process characterization and machine learning-based correlations between interdiffusion layer and expulsion in spot welding

Over the past decades, substantial endeavors have been dedicated to unraveling the intricacies inherent to Resistance Spot Welding (RSW). However, a comprehensive and consensual understanding of the RSW process physics is still lacking, including the exact number of physical phases behind the RSW process. For example, a widely accepted model indicates that metal only starts melting after the peak of dynamic resistance, while the latest research on welding uncoated materials challenges this by suggesting that melting begins around the resistance peak. Furthermore, most of existing physical models only consider welding materials without coatings in a controlled lab setting, whereas coated sheet metal is the norm in real production. Addressing these challenges, this paper introduces an enhanced model for RSW that considers the melting phase of the coating's InterDiffusion Layer (IDL) in Press Hardening Steels (PHS). This phase is believed to influence both welding quality and the occurrence of expulsions. Additionally, the timing at which each phase starts has been determined by analyzing real-time, multi-variable sensing data from various welding scenarios, and a signal processing technique has been devised to automatically identify when these phases begin. Leveraging this refined process understanding and characterization, meaningful explainable features are extracted, and a data-driven multilayer perceptron model is constructed for 1) predicting IDL thickness and 2) detecting expulsions upon predicted IDL thickness. The experimental results validate that the proposed IDL-inclusive model advances existing physical models for RSW and the IDL prediction improves the RSW defect detection and process monitoring.

Paternal peripartum depression: emerging issues and questions on prevention, diagnosis and treatment. A consensus report from the cost action Riseup-PPD

ABSTRACT Introduction Paternal peripartum depression (P-PPD) is a serious and understudied public health problem associated with impaired family functioning and child development. The lack of recognition of P-PPD may result in limited access to both information and professional help. Objective The aim of the study was to review studies on paternal peripartum depression and to identify issues and questions where future research and theory formation are needed. Methods A literature search for systematic reviews, meta-analyses and primary studies was conducted using PubMed, Web of Science, Embase, Scopus, Medline, PsychInfo and Informit databases. Key results within the retrieved articles were summarised and integrated to address the review objectives. Results Based on the literature, the knowledge related to prevalence, screening, risk factorsunique to fathers, management strategies and outcomes of P-PPD is lacking. Currently, there is no consensual understanding of the definition of P-PPD and recommendations for dealing with P-PPD. Limited data were available regarding the barriers preventing fathers from accessing support systems. Conclusion Emerging issues that need to be addressed in future research include: P-PPD definition and pathogenetic pathways; prevention strategies and assessment tools; self-help seeking and engagement with interventions; the cost-effectiveness of P-PPD management; needs of health professionals; effect on child development, and public awareness. Future studies and clinical practice should account the complexities that may arise from the father’s perceptions of health care services. Results from this review highlights the critical issues on how to plan, provide and resource health services, to meet the health needs of fathers.

Relativismo e universalismo linguístico

Language establishes itself as one of the oldest branches - since Ancient Greece -  of systematic investigation. Thus, it is important to emphasize that language is a frequent object of academic analysis in both the social sciences and the exact sciences, but without a consensual understanding of its "nature". The debate focuses mainly on how language emerges in the species and its relation to human thought. So, we analyze two of the main currents of thought that have undertaken linguistic studies with respect to this issue, such as 1. The school of linguistic relativity; and 2. The school of linguistic universalism. For this purpose, it was fundamental to conduct a bibliographic research - in journals, theses and books - which allowed us to grasp the theoretical approach of both schools. Thereby, throughout this article, we seek to understand the different approaches to the relationship between language and thought, in such a way that we  conduct a general analysis of relativism and then address linguistic universalism. Therefore, the debate about language and its relation with thought is establishes as one of the most relevant elements in the history of human society.

The Patriotism of Collegial Idealism and Cooperation

State educational standards prescribing curricular and instructional objectives reveal much about the nation’s lack of consensual understanding of patriotism. For example, many state standards finally encourage a non-committal arms-length approach to the study of American ideals in government and tradition. Yet, if students are to understand the republic in terms of some shared set of ideals, schools need something simple and straight-forward, something akin to a corporate vision. The founding documents are important for detailed study. But something simple and definitive of patriotism must be accessible to all regardless of local idiosyncrasies. State requirements are too diverse, and most states have ignored the idea of patriotic vision altogether. What follows is a position on patriotism that accommodates current state standards, regionalists, globalists, and nationalists. The theme developed is not jingoistic but reflects the understanding of a few who have fought for corporate bloodedness of the kind best suited for national identity and mission writ large

What Is Adult Hippocampal Neurogenesis Good for?

Adult hippocampal neurogenesis is a unique and exceptional process in the mammalian brain that in a lifelong and activity-dependent way generates new excitatory principal neurons. A comprehensive view on their function in greater contexts has now emerged, revealing to which extent the hippocampus (and hence brain and mind) depend on these neurons. Due to a postmitotic period of heightened synaptic plasticity they bias incoming excitation to the dentate gyrus to non-overlapping subnetworks, resulting in pattern separation and the avoidance of catastrophic interference. Temporally, this promotes the flexible integration of novel information into familiar contexts and contributes to episodic memory, which in humans would be critical for autobiographic memory. Together these local effects represent a unique strategy to solve the plasticity-stability dilemma that all learning neuronal networks are facing. Neurogenesis-dependent plasticity also improves memory consolidation. This relates to the surprising involvement of adult neurogenesis in forgetting, which is also hypothesized to be critically relevant for negative plasticity, for example in post-traumatic stress disorder. In addition, adult-born neurons also directly mediate stress-resilience and take part in affective behaviors. Finally, the activity- and experience-dependent plasticity that is contributed by adult neurogenesis is associated with an individualization of the hippocampal circuitry. While a solid and largely consensual understanding of how new neurons contribute to hippocampal function has been reached, an overarching unifying theory that embeds neurogenesis-dependent functionality and effects on connectomics is still missing. More sophisticated multi-electrode electrophysiology, advanced ethologically relevant behavioral tests, and next-generation computational modeling will let us take the next steps.

3Es for AI: Economics, Explanation, Epistemology

This article locates its roots/routes in multiple disciplinary formations and it seeks to advance critical thinking about an aspect of our contemporary socio-technical challenges by bracketing three knowledge formations—artificial intelligence (AI), economics, and epistemology—that have not often been considered together. In doing so, it responds to the growing calls for the necessity of further transdisciplinary engagements that have emanated from work in AI and also from other disciplines. The structure of the argument here is as follows. First, I begin by demonstrating how and why explanation is a problem in AI (“XAI problem”) and what directions are being taken by recent research that draws upon social sciences to address this, noting how there is a conspicuous lack of reference in this literature to economics. Second, I identify and analyze a problem of explanation that has long plagued economics too as a discipline. I show how only a few economists have ever attempted to grapple with this problem and provide their perspectives. Third, I provide an original genealogy of explanation in economics, demonstrating the changing nature of what was meant by an explanation. These systematic changes in consensual understanding of what occurs when something is said to have been “explained”, have reflected the methodological compromises that were rendered necessary to serve different epistemological tensions over time. Lastly, I identify the various relevant historical and conceptual overlaps between economics and AI. I conclude by suggesting that we must pay greater attention to the epistemologies underpinning socio-technical knowledges about the human. The problem of explanation in AI, like the problem of explanation in economics, is perhaps not only, or really, a problem of satisfactory explanation provision alone, but interwoven with questions of competing epistemological and ethical choices and related to the ways in which we choose sociotechnical arrangements and offer consent to be governed by them.

Contradictions of judicial criminal policy

The subject of the study is the criminal policy in the context of contradictions in the functioning of the courts.The purpose of the study is to investigate, which contradictions of criminal policy are generated by a multi-level system of courts, and which mechanisms for overcoming them in order to optimize criminal policy could be found out.The methodology. In modern conditions of diversification of methodological approaches to organizing and conducting political-legal research, it is important not to discard, but to rethink and rediscover the epistemological possibilities of the methods of classical science, especially the method of dialectical analysis.The main results and scope of the study. The use of the category "dialectical contradiction" for the purpose of studying the problems of the functioning of the courts in terms of the interpretation and application of criminal law provisions opens up new possibilities in the study of criminal and judicial policy, as well as determining the prospects for its development. In the study, the law enforcement contradictions of criminal policy refer to the relations between courts of various types and levels that develop in the course of their functioning and reflect the opposite approaches of law enforcement bodies to the interpretation and application of criminal legislation. Considering the level and type of legal proceedings, these contradictions can be summarized in the following groups: (a) between national and international courts; (b) between superior courts of the national legal system; (c) between the courts of various instances of the system of courts of general jurisdiction.The contradictions between national and international courts, emerging in the field of protection of human rights and freedoms, are an objective source of development of judicial practice and policy. The resolution of these contradictions is based on the consensus of various courts and compromise. If the position of the European Court of Human Rights does not contradict the provisions of the Constitution of the Russian Federation, the state adjusts its legal practice in the direction set by the authoritative international instance by means of: (a) direct application of national legislation with due regard for the ECHR’s legal positions; (b) the application of national legislation in its constitutional interpretation by the Constitutional Court of the Russian Federation, which does not differ from the decisions and positions of the ECHR; (c) amending national legal acts in pursuance of ECHR judgments. In exceptional cases, when the position of the European Court touches upon issues of the country's constitutional identity, the contradiction between the international and national legal order is resolved by the Constitutional Court of the Russian Federation on the basis of the priority of constitutional norms.At the level of the superior national courts the contradictions are represented by the differing positions of the Constitutional Court of the Russian Federation and the Supreme Court of the Russian Federation on the assessment and interpretation of criminal law provisions. Such contradictions can be thought of as latent until they are not revealed in constitutional proceedings. The identification and resolution of these contradictions is the most important direction of legal policy in the country; it reflects the consistent solution of the aim of constitutionalization of the criminal law.At the level of the system of courts of general jurisdiction, the concept of "contradiction" can only be applied to those differing approaches of the courts to solving criminal cases that do not go beyond the rule of law. Contradictions arise only when, having correctly established the factual circumstances of the case, the courts disagree in the choice of the legal provision to be applied, although any such choice can be explained and motivated. These contradictions may or may not be related to the quality of criminal legislation. Therefore, the mechanism for their resolution includes not only law revision. It is important to use the capabilities of the judicial system itself to develop a consensual understanding of the textual content of the criminal law and the rules for its application.Conclusions. Overcoming the contradictions of the judicial criminal policy is possible only in the process of communication and dialogue between the courts of different levels on the basis of differentiation of jurisdiction, respect for authority and independence.

Spiritual Needs Assessment in Post-Secular Contexts: An Integrative Review of Questionnaires.

Research across healthcare contexts has shown that, if provided appropriately, spiritual care can be of significant benefit to patients. It can be challenging, however, to incorporate spiritual care in daily practice, not least in post-secular, culturally entwined, and pluralist contexts. The aim of this integrative review was to locate, evaluate and discuss spiritual-needs questionnaires from the post-secular perspective in relation to their applicability in secular healthcare. Eleven questionnaires were evaluated and discussed with a focus on religious/spiritual (RS) wording, local culturally entwined and pluralist contexts, and on whether a consensual understanding between patient and healthcare professional could be expected through RS wording. By highlighting some factors involved in implementing a spiritual-needs questionnaire in diverse cultural and vernacular contexts, this article can assist by providing a general guideline. This article offers an approach to the international exchange and implementation of knowledge, experiences, and best practice in relation to the use of spiritual needs-assessment questionnaires in post-secular contexts.

No Obvious Home: the Public’s Dialogical Creation of Home During the Third Wave of Decolonization

The global crises we currently face, ecological, refugee-related and dealing with austerity arising out of the Covid-19 pandemic share a common feature. Together they have the capacity to call into question shared understandings of what constitutes the physical, political and psychological boundaries of home. Consensual understanding (social representations) of home, if unexamined, risks retaining primordial, stable, bounded and historically continuous dimensions. The focus of this article, to this end, is the public’s understanding of home. The “un-homing” techniques used by populist leaders are brought into dialogue with how citizens, as dialogical selves, talk about home. The contours of common-sense on belonging are being informed; it is proposed by a third wave of decolonization. Stimulus-led interviews (N = 76) were conducted in England, Germany, Ireland, Scotland and Sweden. Dialogical analysis shows the public use two social representations relating to (i) freedom of movement and (ii) how the world is organized. These social representations decolonize home beyond national/transnational boundaries towards the transglobal. Citizens, irrespective of degree of migration, navigate future (in) securities using intergenerational dialogue. This serves to anchor transglobal migration-mobility to intergenerational continuity and the possibilities of travelling together through life. Public dialogue, when diffracted into a spectrum of positions on home, has the capacity to counter black/white, us/them, xenophobic protectionism within nationalist populism. In conclusion, scientific studies which reveal the depths of public capacity may become centrally important to post-pandemic recovery.

Metacognição e seus 50 anos: uma breve história da evolução do conceito

Os estudos em metacognição avançaram nas últimas décadas, todavia, ainda não há um corpo teórico amplo capaz de abarcar as especificidades possíveis de serem estabelecidas. Essa constatação nos levou a realizar um breve histórico da introdução do termo “metacognição”, apresentando uma possibilidade para delimitar sua utilização vinculada às intervenções didáticas no campo educacional. Para isso, texto discute a origem do termo; aponta uma possível instituição de componentes para sua conceitualização a partir de entendimentos consensuais; elabora um mapa dos domínios metacognitivos e assume a reflexão metacognitiva como a expressão que interliga os componentes metacognitivos.

Understanding the dimensions of sport-injury related growth: A DELPHI method approach.

Despite the multitude of adverse physical and psychosocial consequences of sports injury, evidence also highlights the potential for positive benefits in the injury aftermath. The purpose of this study is to address this gap by exploring the dimensions of personal growth following a severe sports injury. A 3-rounds e-Delphi method was utilized to develop a consensual understanding of the dimensions of sport-injury related growth. A panel of 24 psychology of sport injury experts participated in the process. The final list of items obtained was subjected to conventional content analysis to identify general themes. The process led to the development of a 5-dimension model capable of describing athletes' experiences of personal growth following a severe sports-related injury: personal strength, improved social life, health benefits, sport benefits, and social support and recognition. The domains of sport-injury related growth identified here are consistent with growth-domains identified in previous personal growth literature. However, they also highlight the importance of contextualizing the experience of growth. We have captured key elements of sport-injury related growth, domains that can be used as the basis for further psychometric testing and for further interventions to increase adjustment and well-being during the rehabilitation process.

How do biosphere stewards actively shape trajectories of social-ecological change?

The biosphere faces an uncertain future! Embracing change, uncertainty and complexity calls for creative transformative pathways. Biosphere stewardship provides a novel multi actor approach towards sustainability. Despite the critical role of individual environmental stewards, biosphere stewardship emphasizes the importance of collective action, and therefore governance. Biosphere stewardship denotes novel governance configurations with the capacity to effectively approach to sustainability transformation. In this paper we seek to advance understanding of how biosphere stewardship actively shapes trajectories of change to foster social-ecological resilience and human wellbeing. Considering the crucial role of governance and more specifically its two pillars of collaboration and learning, we conduct our study of biosphere stewardship through the lens of adaptive co-management. We first set out a framework for diagnosing and analyzing the process of biosphere stewardship. Secondly, we provide evidenced-based insights from applying the framework in four UNESCO biosphere reserves situated in Canada and Sweden to shed light on how active collective shaping of biosphere stewardship occurs and what it produces. In view of the lack of framework for environmental stewardship, we suggest that the present study makes a considerable contribution by providing an appropriate holistic and systemic framework with operational measures. The study also highlights how the comprehensive and consensual understanding of stewardship is proving to be a means of catalyzing biosphere stewardship by enabling effective crafting of policy design and strategic interventions. Moreover, the application of the framework to four case studies reveals the importance of the governance process attributes (collaboration and learning) in mediating outcomes from biosphere stewardship. Finally, the framework provides the basis to address new stewardship enquiries, which require further research in this field.

The Specter of ‘Politics’ and Ghosts of ‘Alternatives’ Past: Lebanese ‘Civil Society’ and the Antinomies of Contemporary Politics

The Lebanese scene has witnessed important developments since the onset of the garbage crisis, particularly in the translation of ‘civil society’ activism and political disaffection into ‘alternative’ realms of political mobilization and participation. The social movement scene witnessed for the first time on such a large scale the multiplication of campaigns denouncing the political order. However, groups’ contending strategic and ideological orientations raised tensions between tendencies hoping to focus singularly on the garbage crisis and others hoping to place the crisis within its larger structural context. The Hirak’s (movement) inability to affect change compelled several activists towards reformist agendas through the electoral process and logic of gradual ‘change from within.’ The most prominent electoral initiative sought to reclaim the city and representative politics under the name (‘Beirut, My City’). The municipal electoral campaign, however, sidelined contentious political issues and structural inequalities vested in the city in favor of an accommodating developmental programe. Following months of deliberation, Beirut Madinati decided to ‘remain at the local level’, while some of its members joined force with other groups to form nationwide parliamentary electoral alliances, alongside a nascent ‘political party experiment,’ Sabaa (Seven). Exploring the recent developments in ‘alternative’ collective action in Lebanon, this research makes use of a content analysis of Facebook campaigning posts and interview data to study actors’ contending relations to ‘the political.’ The research concludes that rather than reconcile citizens with political participation, nascent groups that claim to represent ‘alternatives’ to the ‘corrupt’ political parties and sectarian political order, instead advance a consensual understanding of politics and social change that is more techno-moral and less contentious.

Beyond Anti-thinking: Psychoanalysis as Politics.

This paper discusses the political nature of psychoanalytic audacity in an era of fake news and disinformation as receptive populations accustom themselves to societal and political misrepresentations of anti-thinking. Against the aggressive rise of anti-thinking that cauterizes individual and societal registration of precarity, the ideological foundation of psychoanalytic inquiry is in the freeing of that which emotionally and ideationally, has felt to be impenetrable, making such contents and expressions available for clarification within the consensual understandings between two very different individuals. Psychoanalysis, in its dyadic pairing, its regularity of meetings, and its continuous action of recognizing what is obscure or hidden, is the heir to the Enlightenment motto, "aude sapere" the ongoing act of daring to question (Kant, 1784). Operating against defensive foreclosure, psychoanalysis conditions the toleration of painful states of mind toward contingent consideration of the causes and effects from which productive future action might be considered. The dyadic engagement of psychoanalytic participants operates as a unitary political organization in witness of the human condition, from within which what was unthinkable becomes nameable, and what is named becomes spoken in clarification of anti-thinking's foreclosures.

The experimental evidence for parapsychological phenomena: A review.

This article presents a comprehensive integration of current experimental evidence and theories about so-called parapsychological (psi) phenomena. Throughout history, people have reported events that seem to violate the common sense view of space and time. Some psychologists have been at the forefront of investigating these phenomena with sophisticated research protocols and theory, while others have devoted much of their careers to criticizing the field. Both stances can be explained by psychologists' expertise on relevant processes such as perception, memory, belief, and conscious and nonconscious processes. This article clarifies the domain of psi, summarizes recent theories from physics and psychology that present psi phenomena as at least plausible, and then provides an overview of recent/updated meta-analyses. The evidence provides cumulative support for the reality of psi, which cannot be readily explained away by the quality of the studies, fraud, selective reporting, experimental or analytical incompetence, or other frequent criticisms. The evidence for psi is comparable to that for established phenomena in psychology and other disciplines, although there is no consensual understanding of them. The article concludes with recommendations for further progress in the field including the use of project and data repositories, conducting multidisciplinary studies with enough power, developing further nonconscious measures of psi and falsifiable theories, analyzing the characteristics of successful sessions and participants, improving the ecological validity of studies, testing how to increase effect sizes, recruiting more researchers at least open to the possibility of psi, and situating psi phenomena within larger domains such as the study of consciousness.

New insights into the origin of remote PPG signals in visible light and infrared

Remote photoplethysmography (PPG) is an optical measurement technique with established applications in vital signs monitoring. Recently, the consensual understanding of blood volume variations (BVVs) as the origin of PPG signals was challenged, raising validity concerns about the remote SpO2 methodology. Recognizing the imperative for new opto-physiological evidence, this investigation supports the volumetric hypothesis with living skin experiments and Monte Carlo simulations of remote PPG-amplitude in visible light (VIS) and infrared (IR). Multilayered models of the skin were developed to simulate the separate contributions from skin layers containing pulsatile arterioles to the PPG signal in the 450–1000 nm range. The simulated spectra were qualitatively compared with observations of the resting and compressed finger pad, and complemented with videocapillaroscopy. Our results indicate that remote PPG systems indeed probe arterial blood. Green wavelengths probe dermal arterioles while red-IR wavelengths also reach subcutaneous BVVs. Owing to stable penetration depths, the red-IR diagnostic window promotes the invariance of SpO2 measurements to skin non-homogeneities.
