An Interview with John Heron: Exploring the Interface between Cooperative Inquiry and Transpersonal Studies

In this interview, John Heron—the founder of cooperative inquiry (CI; Heron, 1996, 1998)—discusses this experiential, participatory approach to research and learning with participatory research special issue guest editor Olga Sohmer. After presenting a summary of cooperative inquiry, Heron and Sohmer discuss CI in the context of transpersonal studies, including past and prospective future applications. Questioning the emphasis on “trans” in transpersonal, Heron unfolds the three dimensions of human spirituality that CI engages and offers a vision for transpersonal studies in light of CI ideals. Additional themes that are explored include cultivating authentic relationships in CI, the role of the nonhuman natural world in CI, practices based on CI principles that can be used in daily life, applying extended epistemology and radical assessment in education, self-generating culture, and the role of CI in human evolution

An Embodied Spiritual Inquiry into the Nature of Human Boundaries: Outcomes of a Participatory Approach to Transpersonal Education and Research

Embodied spiritual inquiry (ESI) is a radical approach to integral and transpersonal education and research offered as a graduate course at the California Institute of Integral Studies (CIIS). Inspired by elements of participatory research and cooperative inquiry, ESI applies interactive embodied meditations to access multiple ways of knowing (e.g., somatic, vital, emotional, mental, contemplative) and mindfully inquire into collaboratively decided questions. This article presents the learning outcomes of an inquiry into the nature of human boundaries within and between co-inquirers, providing an example of how ESI is implemented in the classroom and can be used to study transpersonal subject matter. In particular, the study found that boundaries were experienced in terms of their dynamic effects rather than as static qualities, with a relationship between dissociation and overly firm boundaries, as well as a relationship between integration/merging and more varied combinations of firm and permeable boundaries. Other notable inquiry outcomes include the identification of (a) experiential qualities of the states of dissociation, merging, and integration; (b) a recursive relationship between fear and trust in the modulation of optimal interpersonal boundaries; and (c) the phenomenon of shared emergent experience between practitioners, which suggests the existence of an intersubjective transpersonal field

Automated Performance Assessment in Transoesophageal Echocardiography with Convolutional Neural Networks

Transoesophageal echocardiography (TEE) is a valuable diagnostic and monitoring imaging modality. Proper image acquisition is essential for diagnosis, yet current assessment techniques are solely based on manual expert review. This paper presents a supervised deep learning framework for automatically evaluating and grading the quality of TEE images. To obtain the necessary dataset, 38 participants of varied experience performed TEE exams with a high-fidelity virtual reality (VR) platform. Two Convolutional Neural Network (CNN) architectures, AlexNet and VGG, structured to perform regression, were finetuned and validated on manually graded images from three evaluators. Two different scoring strategies, a criteria-based percentage and an overall general impression, were used. The developed CNN models estimate the average score with a root mean square accuracy ranging between 84% − 93%, indicating the ability to replicate expert valuation. Proposed strategies for automated TEE assessment can have a significant impact on the training process of new TEE operators, providing direct feedback and facilitating the development of the necessary dexterous skills

Optical bench development for LISA

For observation of gravitational waves at frequencies between 30 μHz and 1 Hz, the LISA mission will be implemented in a triangular constellation of three identical spacecraft, which are mutually linked by laser interferometry in an active transponder scheme over a 5 million kilometer arm length. On the end point of each laser link, remote and local beam metrology with respect to inertial proof masses inside the spacecraft is realized by the LISA Optical Bench. It implements further- more various ancillary functions such as point-ahead correction, acquisition sensing, transmit beam conditioning, and laser redundancy switching. A comprehensive design of the Optical Bench has been developed, which includes all of the above mentioned functions and at the same time ensures manufacturability on the basis of hydroxide catalysis bonding, an ultrastable integration technology already perfected in the context of LISA's technology demonstrator mission LISA Pathfinder. Essential elements of this design have been validated by dedicated pre-investigations. These include the demonstration of polarizing heterodyne interferometry at the required Picometer and Nanoradian performance levels, the investigation of potential non-reciprocal noise sources in the so-called backlink fiber, as well as the development of a laser redundancy switch breadboard

Variability of black carbon mass concentrations, sub-micrometer particle number concentrations and size distributions: results of the German Ultrafine Aerosol Network ranging from city street to High Alpine locations

This work reports the first statistical analysis of multi-annual data on tropospheric aerosols from the German Ultrafine Aerosol Network (GUAN). Compared to other networks worldwide, GUAN with 17 measurement locations has the most sites equipped with particle number size distribution (PNSD) and equivalent black carbon (eBC) instruments and the most site categories in Germany ranging from city street/roadside to High Alpine. As we know, the variations of eBC and particle number concentration (PNC) are influenced by several factors such as source, transformation, transport and deposition. The dominant controlling factor for different pollutant parameters might be varied, leading to the different spatio-temporal variations among the measured parameters. Currently, a study of spatio-temporal variations of PNSD and eBC considering the influences of both site categories and spatial scale is still missing. Based on the multi-site dataset of GUAN, the goal of this study is to investigate how pollutant parameters may interfere with spatial characteristics and site categories

Gender Differences in Myogenic Regulation along the Vascular Tree of the Gerbil Cochlea

Regulation of cochlear blood flow is critical for hearing due to its exquisite sensitivity to ischemia and oxidative stress. Many forms of hearing loss such as sensorineural hearing loss and presbyacusis may involve or be aggravated by blood flow disorders. Animal experiments and clinical outcomes further suggest that there is a gender preference in hearing loss, with males being more susceptible. Autoregulation of cochlear blood flow has been demonstrated in some animal models in vivo, suggesting that similar to the brain, blood vessels supplying the cochlea have the ability to control flow within normal limits, despite variations in systemic blood pressure. Here, we investigated myogenic regulation in the cochlear blood supply of the Mongolian gerbil, a widely used animal model in hearing research. The cochlear blood supply originates at the basilar artery, followed by the anterior inferior cerebellar artery, and inside the inner ear, by the spiral modiolar artery and the radiating arterioles that supply the capillary beds of the spiral ligament and stria vascularis. Arteries from male and female gerbils were isolated and pressurized using a concentric pipette system. Diameter changes in response to increasing luminal pressures were recorded by laser scanning microscopy. Our results show that cochlear vessels from male and female gerbils exhibit myogenic regulation but with important differences. Whereas in male gerbils, both spiral modiolar arteries and radiating arterioles exhibited pressure-dependent tone, in females, only radiating arterioles had this property. Male spiral modiolar arteries responded more to L-NNA than female spiral modiolar arteries, suggesting that NO-dependent mechanisms play a bigger role in the myogenic regulation of male than female gerbil cochlear vessels
