ObjectivesMany older adults with visual impairment also have significant hearing loss. The aim was to investigate the effectiveness of a newly developed Dual Sensory Loss protocol on communication and wellbeing of older persons with DSL and their communication partners in the Netherlands and Belgium.MethodsParticipants and their communication partners were randomized in the “DSL-protocol” intervention group or a waiting-list control group. The intervention took 3 to 5 weeks. Occupational therapists focused on optimal use of hearing aids, home-environment modifications and effective communication (...) strategies. The primary outcome was the Communication Strategies domain of the Communication Profile for the Hearing Impaired. Secondary outcomes measured in participants were the Low Vision Quality Of Life Adjustment subscale, the Center for Epidemiological Studies - Depression Scale, De Jong Gierveld Loneliness Scale and the Fatigue Assessment Scale. The Hearing Handicap and Disability Inventory - Reaction of Others subscale and the Care-related Quality of Life - 7 Dimensions was measured in communication partners. Measurements were taken at baseline and 3-month follow-up. Linear mixed models were used to analyze effects between groups over time for every outcome measure.ResultsIntention-to-treat analyses showed a significant effect of the DSL-protocol on the use of verbal strategies in favor of the control group, however, this effect was non-significant after adjustment for confounding. Effect sizes of other outcomes varied between −0.23 [−0.57, 0.12] and 0.30 [−0.05, 0.64]. The LMM showed a significant effect on the HHDI-Reaction of others scale in favor of communication partners in the treatment group, however, the effect did not remain significant at a 0.01 significance level and the effect size was very small and non-significant 0.12, 95% CI [−0.27 to 0.51]. Adjusted analyses did not reveal treatment effects.ConclusionThe DSL-protocol did not clearly contribute to the enhancement of communication and wellbeing in DSL-patients. Possible reasons for the lack of effects are OTs not being comfortable giving advice on communication and psychosocial issues or the short-term treatment and follow-up period. Further study is warranted to find out how the protocol may be adapted or whether it is necessary to involve mental healthcare professionals.Clinical Trial Registrationwww.ClinicalTrials.gov, identifier NTR2843.

ABSTRCTIn recent times, Information and Communication Technology (ICT) hasbeen developed and widely spread around world. ICT is used in various sectorsand considered a basis in the emergence of some important technologies such asvirtual reality technology. Virtual Reality (VR) is a special technology as anadvanced technology connected to several fields, e.g. training, learning, science,engineering, medicine, military, etc. VR has great potentials which enabled toperform several phenomena and experiments. Hence, several scenarios havebecome available. The purpose of this study is to shed light (...) on virtual realitytechnology and list a glimpse of common publications and studies involved. (shrink)

Some authors maintain that anti-intellectualism faces a general epistemic problem of explaining the cognitive aspect of know-how, and answering the question of why know-how as a kind of disposition is to be considered a distinct kind of knowledge. In the present paper, I argue for a solution to this problem, the central idea of which is that there is a broader sense of knowledge to which both knowledge-that and knowledge-how belong. I present two versions of this solution. According to the (...) first version, know-how is a distinct kind of knowledge since there is a general analyzable category of knowledge under which both know-how and know-that fall. This general category is analyzed into three components: a success component, an externalist anti-luck component, and an internalist anti-luck component. According to the second version of the solution, know-how is a distinct kind of knowledge since there is an unanalyzable analogical conception of knowledge that comes first in both the theoretical realm (as propositional knowledge) and the practical realm (as know-how). Both versions of the solution are plausible since they distinguish between know-how and knacks in an anti-intellectualist manner by positing that there is an internal relation between know-how and non-propositional intentionality.

During the COVID-19 epidemic, personal safety has received increasing attention, leading to behavioral changes. Mobile-wallet makes it easier for people to keep social distance, which helps stop the spread of the COVID-19 virus. Evolving Internet technology has brought about changes in consumer lifestyle. The current situation of COVID-19 has created a business environment to shift from traditional ways and adopt e-commerce solutions worldwide. Grounded in technology acceptance model theory, this study’s objective is two-fold: First, this study intends to examine perceived (...) susceptibility to COVID-19, perceived severity of COVID-19, insecurity and discomfort as the predictors of perceived usefulness and perceived ease of use. Second, the current research intends to test the moderating effect of electronic words-of-mouth on the relationship between attitude and usage intention. Using survey methods, 226 usable responses were collected through a mall intercept survey in Pakistan. Data were analyzed using partial least square. The results revealed that PEOU and PU positively influence attitude toward M-wallet. This study has found that attitude positively influences the usage intention in adopting M-wallet. The results also support the moderating role of eWOM. These findings contribute to the marketing literature in several ways, particularly in Pakistan. This is the first study to use eWOM as a moderating variable in the TAM theory. In addition, this study adds to the current body of knowledge by considering eWOM as a multi-dimensional construct novel in m-wallet literature. (shrink)

We apply an online optimization process based on machine learning to the production of Bose-Einstein condensates. BEC is typically created with an exponential evaporation ramp that is optimal for ergodic dynamics with two-body s-wave interactions and no other loss rates, but likely sub-optimal for real experiments. Through repeated machine-controlled scientific experimentation and observations our ’learner’ discovers an optimal evaporation ramp for BEC production. In contrast to previous work, our learner uses a Gaussian process to develop a statistical model of the (...) relationship between the parameters it controls and the quality of the BEC produced. We demonstrate that the Gaussian process machine learner is able to discover a ramp that produces high quality BECs in 10 times fewer iterations than a previously used online optimization technique. Furthermore, we show the internal model developed can be used to determine which parameters are essential in BEC creation and which are unimportant, providing insight into the optimization process of the system.

A hub and spoke model offers an effective and efficient approach to providing informed guidance to those who need it. The National Center for Ethics in Health Care (NCEHC) at the Veterans Health Administration, Department of Veterans Affairs, is the largest known hub and spoke healthcare ethics delivery model. In this article, we describe ways NCEHC’s hub and spoke configuration succeeded during the COVID- 19 pandemic, as well as limitations of the model and possible improvements to inform adoption at other (...) healthcare systems.

In lieu of an abstract, here is a brief excerpt of the content:69 WILLIAM ROBERTSON AND DAVID HUME: THREE LETTERS The relationship between David Hume and his fellow Scottish historian William Robertson has always seemed one-sided. Despite the existence of fifteen letters to Robertson in the standard volumes of Hume's correspondence,1 Hume scholars have long had reason to regret the lack of a single extant letter from Robertson to Hume. None are to be found, for example, where one would most (...) expect them to be — in the Royal Society of Edinburgh, alongside the letters to Hume from various other Moderate clergymen and literati in Robertson's circle, such as Hugh Blair and Adam Ferguson. Fortunately, however, two of Robertson's letters to Hume (numbered II and III below) have now turned up where one would not expect them to be — among Robertson's own correspondence in the Robertson2 Macdonald Papers, National Library of Scotland. They are not mere drafts, such as one is accustomed to find among an author's private papers; rather, they are autograph signed letters that appear to have actually been posted. How and when they found their way back to Robertson's personal papers, and what became of the rest of Robertson's letters to Hume, are questions open to speculation. For the moment we are grateful for the letters we now have, neither of which is known to have been published before in whole or in part. Nor has Hume been identified before as the recipient of either of these letters, though internal evidence makes it clear that he was. Both letters date from the late 1760s, when Hume was living in London and Robertson was at the peak of his multi-faceted career in Edinburgh as university principal, parish minister, ecclesiastical leader, and man of letters. The first of them, dated 27 March 1767, was sent to Hume in his capacity as under- 70 secretary of state in the Northern Department (an office he held from February 1767 to January 1768). It is plainly a reply to a letter of 19 March, in which Hume had discussed three topics to which Robertson was 5 responding: Robertson's efforts to secure a military chaplaincy for a certain Scottish minister (evidently named Brodie); Conway's role in the famous dispute between Hume and Rousseau; and the public response to Adam Ferguson's newly published Essay on the History of Civil Society. In addition Robertson addresses a matter that Hume had apparently broached with him at some earlier time: the attempt to find a suitable Scottish church to which Hume might obtain a crown presentation for his nephews' tutor, the Rev. Christopher Tait. The letter concludes on a note of admiration that is characteristic not only of Robertson but of most of Hume's other "Protestant Pastors" in Scotland. The second letter to Hume, dated 31 January 1769, is chiefly concerned with the forthcoming publication of Robertson's History of Charles V and the French translation of it by J.-B.-A. Suard — subjects that had been treated in two letters from Hume to 7 Robertson of autumn 1768. It also contains a strong recommendation for a bright young Scottish writer (in both the legal and literary senses of that term) who would one day become Robertson's most vitriolic critic: Gilbert Stuart. On the personal side, there is encouragement for the now unemployed Hume to return to Edinburgh, as he was then threatening to do, after his "great glut of society" at Paris and London, and there are allusions in the closing paragraph to Hume's part in introducing his friend to polite society when Robertson had visited London to arrange the publication of Charles V in the spring of 1768. 71 To these two letters from Robertson we have prefixed a third from earlier in the same decade, one Q not actually addressed to Hume but largely about him. Robertson wrote it to their common friend Gilbert Elliot (later Sir Gilbert Elliot) on 8 March 1762, two days before the Town Council elected Robertson principal of Edinburgh University. The first paragraph deals with the principalship and relates to Hume only indirectly, as we point out in a footnote. The second paragraph, however, contains interesting... (shrink)

This text explores how human beings construe experience: experience as a resource, as a potential for understanding, representing and acting on reality.

The vast majority of contributions to the literature on spirituality in nursing make extravagant claims about transcendence, eternity, the numinous, higher powers, higher levels of existence, invisible forces, cosmic unity, the essence of humanity, or other supernatural concepts. Typically, these assertions are made without the support of argument or evidence; and, as a consequence, alternative ways of theorizing ‘spirituality’ have been closed off, while the lack of consistent scholarship has turned the topic into a metaphysical backwater. In this paper, I (...) adopt a different premise, rejecting unsupported claims, and surveying the ‘spirituality’ terrain from a naturalistic and reductionist perspective. I argue that, if we rid ourselves of non‐naturalistic assumptions, we will discover theoretical and clinical resources in health psychology, social psychology, neuropsychology, and pharmacopsychology – resources which confirm that it is possible to conceptualize the study of existential concerns, and how health professionals might respond to them, in a properly scientific manner. In order to illustrate the potential usefulness of these resources, I will take palliative care as an example. (shrink)

Quantum mechanical measurements on a physical system are represented by observables - Hermitian operators on the state space of the observed system. It is an important question whether all observables may be realized, in principle, as measurements on a physical system. Dirac’s influential text ( [1], page 37) makes the following assertion on the question: The question now presents itself – Can every observable be measured? The answer theoretically is yes. In practice it may be very awkward, or perhaps even (...) beyond the ingenuity of the experimenter, to devise an apparatus which could measure some particular observable, but the theory always allows one to imagine that the measurement can be made. This Letter re-examines the question of whether it is possible, even in principle, to measure every quantum mechanical observable. Unexpectedly, ideas from com-. (shrink)

This paper investigates four questions related to ethical issues associated with the involvement of engineers and scientists in 'military work', including the influence of ethical values and beliefs, the role of gendered perspectives and moves beyond the purely technical. It fits strongly into a human (and planet)-centred systems perspective and extends my previous AI and Society papers on othering and narrative ethics, and ethics and social responsibility. It has two main contributions. The first involves an analysis of the literature through (...) the application of different ethical theories and the application of gendered analysis to discussion of masculinities in engineering and the military. The second is a survey of scientists and engineers to investigate their opinions and experiences. The conclusions draw together the results of these two contributions to provide preliminary responses to the four questions and include a series of recommendations covering education and training, ethical approval of work not involving human participants or animals, the need for organisational support, approaches covering wider perspectives and the encouragement of individual ethical commitment.
