Virtual Environment for Topographical Orientation (VETO): Clinical Rationale and Technical Characteristics
Authors: Bertella Laura , Marchi Stefano , Riva Giuseppe 
Published: July 2002

The lack of spatial orientation often serves as a warning light for a diffused cerebral impairment, such as the one at the origin of a confusional state or of a mental disorder. Topographical orientation disorders may be the expression of memory or attention deficits, unilateral spatial negligence, or elementary visuoperceptive disorders. In a minority of cases, spatial disorientation presents as an isolated disorder and is the expression of a focal brain lesion. The paper describes the clinical rationale and the technical characteristics of the Virtual Environment for Topographical Orientation (VETO). VETO is used both as a complementary tool for the assessment of topographical orientation disorders and to increase the possibilities of management of these patients from a rehabilitative point of view. VETO is based on the recent theoretical model of wayfinding in virtual environments proposed by Chen and Stanney (1999). This model suggests that wayfinders generally start from the direct perception of the environment or from the recall of a cognitive map. In terms of direct perception of the environment, landmark knowledge is acquired by directly viewing indirect representation such as photographs. In terms of cognitive mapping, procedure/route knowledge is acquired through direct experience or through simulated experience and stored in memory. Our hypothesis is that the study of spatial orientation through specific VETO tasks, both in normal samples and in subjects affected by topographical disorientation, can bring greater comprehension and validation of the cognitive models of spatial orientation present in literature.
THE SETUPATIS, THE DUTCH, AND OTHER BANDITS IN EIGHTEENTH-CENTURY RAMNAD (SOUTH INDIA)
Authors: Bes Lennart 
Published: July 2002

AbstractIn Ramnad, bandits could be king. The open-ended political culture of this South Indian kingdom presented even people on the margins of society with opportunities to attain political power. Likewise, the VOC (Dutch East India Company), operating from the coastal frontier of the kingdom, played a significant role in the political arena of Ramnad. Given this similarity, it may be asked whether the Dutch were regarded as neutral outsiders (as they themselves thought they were) or rather as an indigenous marginal power. By comparing the internal and regional relations of Ramnad with its contacts with the VOC, this article attempts to determine the kingdom's perception of the Company. In Ramnad, could the Dutch be bandits? En Ramnad, un royaume dans l'Inde méridional, il arrive que le bandit se fait roi. La culture politique, ainsi que les avenues du pouvoir y furent en principe ouvertes à tous; aux marginaux indigènes, vivants dans les terres sèches périphériques, autant qu'aux fonctionnaires de la compagnie néerlandaise des Indes Orientales, la VOC, qui avait un comptoir sur le littoral. Elle se considerait neutre. Toutefois elle allait jouer un rôle important dans l'arène politique de Ramnad. Or, au niveau conceptuel la question se pose si la perspective indigène différenciait entre le roturier indigène d'au-delà de la terre de grande culture, et l'aventurier étranger, ou par contre les confondait l'un l'autre. Cet article se propose d'y voir plus clair par l'étude des liens internes et régionals entretenus par le centre politique de Ramnad, en comparant ceux-ci avec les relations vis-à-vis la VOC pour en déduire le statut social des Hollandais dans la société indigène.
The Reductionist and Compatibilist Argument of Epicurus' On Nature, Book 25
Authors: O'Keefe Tim 
Published: July 2002

AbstractEpicurus' On Nature 25 is the key text for anti-reductionist interpretations of Epicurus' philosophy of mind. In it, Epicurus is trying to argue against those, like Democritus, who say that everything occurs 'of necessity,' and in the course of this argument, he says many things that appear to conflict with an Identity Theory of Mind and with causal determinism. In this paper, I engage in a close reading of this text in order to show that it does not contain any clear statement of either a doctrine of radically emergent properties and "downwards causation" (contra David Sedley) or of the non-reducibility of the mental to the atomic (contra Julia Annas). I argue that Epicurus' main thesis is that we cannot consistently argue against our conception of ourselves as rational agents, and that it is our reason that allows us to reform our characters, control our actions, and blame and praise one another appropriately. The way that Epicurus describes the development and causal efficacy of reason in On Nature book 25 is consistent both with reductionism and (more surprisingly) with causal determinism.
Death of a Companion Cat or Dog and Human Bereavement: Psychosocial Variables
Authors: Stokes Shelley , Planchon Lynn , Templer Donald , Keller Jacqueline 
Published: July 2002

AbstractThis study found that death depression, general depression, and positive attitudes toward, and attachment to, companion animals were associated with greater grief following the death of cats and dogs both in a veterinary client group who had recently lost their companion animals and in a college student group with a history of companion animal loss. The correlations of both the above variables and the demographic and death circumstance variables tended to be higher with the veterinary clients. Death of a dog by accident as opposed to illness correlated .81 with extended grief in the veterinary clients. Not having their dogs euthanized correlated .70 with extended grief in this group as well.
IMPLIED ANTECEDENTS IN JOB XL 2B AND PROVERBS III 6A
Authors: Johnson Timothy 
Published: July 2002

AbstractThis article proposes a solution for identifying two problematic antecedents in two separate verses of the Hebrew Bible. I suggest that these antecedents are implied nouns instead of specific nouns standing in the text. The first example of this occurs in Job lx 2b where the third person singular feminine suffix refers to an implied noun that is associated with a nearby participle. The second more controversial example is found in Prov. iii 6a. Here the LXX, whose antecedent is an implied noun, serves as the necessary guide for opening the way to understanding the MT, where another implied noun is used. In each verse, clarity of interpretation is gained, with the latter analysis resulting in a more severe break from traditional views.
Female activity patterns and aggressiveness in the strawberry poison frog Dendrobates pumilio (Anura: Dendrobatidae)
Authors: Haase Annely , Pröhl Heike 
Published: July 2002

AbstractFemale strawberry poison frogs (Dendrobates pumilio) exhibit highly evolved maternal care, including tadpole transport and tadpole provisioning with unfertilized eggs. We observed that tadpole-rearing and mating activity are mutually exclusive behavioural states in a Costa Rican population. Tadpole-rearing females did not engage in courtship activity. Only non-rearing females courted. Non-rearing females occupied larger home ranges than tadpole-rearing females, which may be related to female selection of mates. For the first time aggressive female-female interactions were observed in the field. Tadpole-rearing females were significantly more aggressive than non-rearing females, especially in the vicinity of their offspring-rearing sites. Las hembras de la ranita roja Dendrobates pumilio ejecutan cuidado parental altamente desarrollado que incluye el transporte y la alimentación de los renacuajos. En una población costaricense encontramos que el cuido materno y la actvidad sexual son comportamientos mutualmente exclusivos: Las hembras que estan cuidando a su cría son sexualmente inactivas, solamente las hembras sin renacuajos se aparean. Las hembras sexualmente activas poseian un rango de actividad más grande que las hembras cuidando a renacuajos. Los rangos de actividad en el primer grupo de hembras eran más grandes probablemente porque ellas visitan los territorios de varios machos con el fin de seleccionar una pareja. Además, por la primera vez interacciones aggressivas entre las hembras de la ranita roja fueron observados en el campo, siendo más aggressivas las hembras con rencuajos, particularmente en la vencidad de los hábitats de su cría.
Taking a Glance at the Environment: Prolegomena to an Ethics of the Environment
Authors: Casey Edward 
Published: July 2002

AbstractIt is remarkable how much we can understand about an environmental problem at a mere glance. By means of a glance - at once quick and comprehensive - we can detect that something is going wrong in a given environmental circumstance, and we can even begin to suspect what needs to be done to rectify the situation. In this paper I explore the unsuspected power of the glance in environmental thought and practice, drawing special lessons for an ethics of the environment. Specific examples are analyzed, and authors as diverse as John Dewey and Gilles Deleuze and Felix Guattari are invoked in an effort to develop a coherent vision of how the human glance helps to locate and remedy environmental crises.
Nature Godly and Beautiful: The Iconic Earth
Authors: Foltz Bruce 
Published: July 2002

AbstractRooted in a tradition of thought and spirituality akin to, yet other than, the onto-theology of the Latin West, the aesthetico-theological experience of the Byzantine icon can help articulate aesthetic and numinous elements of our relation to nature that environmental philosophy should no longer ignore. In contrast to the technical mastery of the natural in Western art inaugurated by the Renaissance, itself related to the emerged technological mastery of nature in the late Middle Ages, the iconic sensibility characteristic of the Byzantine East exhibits an experience of materiality common to non-Western humanity, seeing nature as a visible window to the invinsible, a lintel of the holy. A series of correlations between features of iconic seeing and exemplary encounters with the natural environment by prominent naturalists elaborates this thesis, along with examples from the later writings of Dostoevsky, who looked to divine beauty to save the earth.
The Listening Eye: Nietzsche and Levinas
Authors: Schroeder Brian 
Published: July 2002

AbstractNietzsche's recognition of existence as an ever-shifting play of surface appearances presages his "revaluation of all values," his response to those who would stabilize becoming by metaphysically reifying it as being. Nietzsche arguably provides Levinas with his deepest ethical challenge. Consequently, Levinas himself undertakes a similar revaluation of the ground of traditional values and of the subject. Both put forth heterodox notions of subjectivity insofar as the subject is constituted by a radical exteriority that is paradoxically realized as such interiorly. However, Levinas repudiates the post-modern conception of the subject as an empty, fragmented phantasm (a position often attributed to Nietzsche), the hollow legacy of a now debunked and defunct modernist project, characterizing his ethical philosophy as a "defense of subjectivity." Nietzsche and Levinas simultaneously invert and intertwine the traditional hierarchical relation between seeing and hearing. In doing so, they reveal essential dimensions of the ethical relationship that would appear to be contradictory, self-negating, or at least incompatible. However, they also have their sights set on a similar site - that of the "eye that listens." This essay interrogates the role that the metaphor of the "listening eye" plays in determining their respective conceptions of subjectivity and ethics. Both employ this provocative and necessarily ambiguous metaphor to emphasize the radical role that teaching plays in their philosophies.

ImportancePatients with angina and no obstructive coronary artery disease frequently have coronary vasomotor dysfunction as underlying pathophysiological mechanism, comprising epicardial spasm, microvascular spasm, and/or microcirculatory dysfunction. These endotypes can be diagnosed by invasive coronary function testing which has previously shown to be safe in tertiary and expert centers.ObjectiveTo determine the prevalence of vasomotor dysfunction in patients with angina and no obstructive coronary artery disease who were clinically referred for a coronary function test (CFT); and assess safety and feasibility of a CFT.Design, Setting, and ParticipantsThis quality improvement study was performed using the Netherlands Registry of Invasive Coronary Vasomotor Function Testing (NL-CFT), a prospective, observational registry, in 15 participating hospitals (2 tertiary and 13 nontertiary). Patients with angina and no obstructive coronary artery disease who were referred for a clinically indicated CFT between December 2020 and January 2024 were included.Main Outcomes and MeasuresA complete CFT consisted of acetylcholine spasm provocation testing and assessment of microcirculatory function. Prevalence of different endotypes based on test results and overall safety were assessed.ResultsAmong a total of 1207 patients included, 978 (81%) were female; and the mean (SD) age was 60 (10) years. The prevalence of coronary vasomotor dysfunction was very high (78%). There were 11 (0.9%) major and 10 (0.8%) minor complications reported. Of them, 3 major and all minor were definitely related to the coronary function test. No procedural death, myocardial infarction, or stroke was observed. No differences were found in the occurrence of complications between tertiary and nontertiary centers.Conclusions and RelevanceThis study found that a CFT was feasible and safe to perform in both tertiary and nontertiary centers with a high diagnostic yield.
Aging and Technology
Authors: Formosa Marvin 
Published: February 2025

Abstract
Technology certainly plays a key role in enabling higher levels of active and healthy aging in later life. A growing number of studies are evidencing the benefits of technology for older persons from lower levels of depression and loneliness to higher levels of social support, life satisfaction, purpose in life, and social capital. One central concern, however, concerns the unequal take‐up of digital citizenship between younger and older generations, namely, the age digital divide, as older persons across the world are less likely to be competent in or to use technology. Advances in telemedicine and health‐related assistive technologies have made it possible for older persons to connect with their healthcare providers virtually and enabled them to perform activities of daily living.

AbstractBackgroundTo investigate the effect of bladder volume (BV) and bladder shape on consistency and treatment interruption in prostate cancer radiotherapy (RT).MethodsA total of 275 patients who underwent radical prostate cancer RT in our institution from April 2015 to December 2022 were enrolled. Bladder height, bladder width, and bladder length were defined and recorded. The receiver operating characteristic (ROC) curves were used to evaluate the best cut‐off point for bladder shape. Logistic regression analysis was used to analyze the relationship between setup errors and bladder shapes and BV.ResultsBased on the ROC curves for 275 patients, the bladder shapes were classified into three: (a) the elongated bladder, (b) the spherical bladder, and (c) the oval bladder. Sixty‐six prostate cancer patients (1611 CBCTs) were randomly selected proportionally. It was found that bladder shape has a greater impact on setup errors than BV (BV: OR = 1.470, p = 0.037; bladder shape: OR = 2.013, p < 0.001), and the setup error of the spherical bladder in anterior–posterior (AP) direction was greater than the others (p < 0.001). In addition, the shape consistency of the spherical bladder was the worst (43.0%) during RT. Compared with the inconsistent group, the group with the same bladder shape had higher consistency in BV(CBCT/CT) (p < 0.001), and a smaller setup error in the AP direction (p < 0.001). Similarly, the treatment interruption fractions were highest in spherical bladder RT.ConclusionsMore specific bladder filling requirements should be developed for different bladder shapes. More attention should be paid to the spherical bladder for precise RT.

AbstractPurposeTo present a methodology for the estimation of conceptus dose prior to the completion of a medically required and justified interventional radiology or cardiology procedure.Materials and MethodsThe free of charge National Cancer Institute dosimetry system for Radiography and Fluoroscopy dose calculator tool was adopted to estimate organ absorbed doses through Monte Carlo radiation transport. A procedure was developed for required data collection ahead of the study for dose estimation. This information was used to build the input to the dose calculator tool. Data inclusion and assumption considerations were discussed for final report drafting and communications with the intended interventionalist.ResultsImplementation of this methodology has been used to support pre‐procedural decision making for our institutions interventionalists. Pre‐procedural conceptus dose estimates permitted an educated assessment of the risk‐benefit of the potential radiation exposure to the patient and conceptus against the medical necessity of the procedure. It can also guide the real‐time dose monitoring during the procedure when a maximum permissible cumulative air kerma (CAK) level is determined before the procedure.ConclusionA methodology for the estimation of conceptus dose prior to the completion of an interventional fluoroscopy procedure was developed. Due to the prospective nature of this dose estimation methodology, the model relies heavily on professional experience and, when available, quantitative metrics.
Evaluating the use of diagnostic CT with flattening filter free beams for palliative radiotherapy: Dosimetric impact of scanner calibration variability
Authors: Van de Kleut Madeleine L. , Buckley Lesley A. , Ali Elsayed S. M. 
Published: February 2025

AbstractPurposePalliative radiotherapy comprises a significant portion of the radiation treatment workload. Volumetric‐modulated arc therapy (VMAT) improves dose conformity and, in conjunction with flattening filter free (FFF) delivery, can decrease treatment times, both of which are desirable in a population with a high probability of retreatment with large palliative doses per fraction. Combining FFF and VMAT delivery with planning based on previously acquired diagnostic computed tomography (CT) scans has the potential to further expedite palliative treatment. This study evaluated the dosimetric uncertainty of using FFF beams with VMAT delivery on CT images acquired from different diagnostic vendors, and between different x‐ray tube energies, in the palliative setting.MethodsCT‐relative electron density (CT‐RED) curves were acquired for the local CT simulator at 100, 120, and 140 kVp, and for two diagnostic CT scanners at 120 kVp. Thirty palliative VMAT plans were recalculated for each CT‐RED curve, with 6 MV flat, 6 FFF, and 10 FFF beams. The doses to 95% and 2% of the PTV, the maximum point dose to the spinal canal and esophagus, and the mean dose to the kidneys were compared between recalculated plans.ResultsComparing the dose clouds for a given fluence map calculated with CT‐RED curves from different CT scanners at 120 kVp, the mean dose difference was at most 0.3% for each DVH metric. Similar results were reported when comparing dose clouds calculated with CT‐RED curves for 100, 120, and 140 kVp on the CT simulator.ConclusionThe results of this study confirm that diagnostic scans acquired on machines different from the CT simulator associated with the TPS, are appropriate for VMAT treatment planning in the palliative setting with FFF photon beams.
Optimizing Dehydration Systems: Implementing Model Reference Adaptive Control for Enhanced Efficiency

Published: February 2025

ABSTRACTThis study presents a robust control framework for enhancing the performance of thermal systems with significant input‐induced delays, using a cabin dehydrator as a representative case study. The proposed Model Reference Adaptive Control (MRAC) strategy leverages a reference model to emulate desired system dynamics, enabling adaptive adjustments to maintain optimal performance under varying operating conditions. Stability of the system is rigorously established through Lyapunov‐based analysis, ensuring global asymptotic stability. Additionally, the frequency response of the system, characterized using Bode plots, provides critical insights into the bandwidth and responsiveness of the control strategies. A comparative evaluation is conducted with classical PD and PID controllers as well as a simplified MRAC design to highlight the advantages of the complete MRAC framework. The analysis includes stability metrics such as gain and phase margins, offering a quantitative assessment of the robustness of each controller. Experimental validation further evaluates the proposed approach in terms of its effectiveness in regulating temperature and preserving active substances during the dehydration process. The findings underscore the MRAC framework as a promising solution for achieving precise and adaptive thermal regulation in systems subject to delays.
