AbstractRecent evidence suggest that our experience of time is directly and intrinsically computed within the motor system. Accordingly, a variety of studies have demonstrated that concurrent movement impacts the estimate of temporal duration, such that perceived time is shifted towards the duration of movement. In order to investigate the role of the motor system, we tested human subjects (n=40) on a novel task combining reaching and time perception. In this task, subjects were required to move a robotic manipulandum to one of two physical locations to categorize a concurrently timed suprasecond auditory stimulus as “long” or “short”, relative to a running average criterion. Critically, subjects were divided into two groups: one in which movement during the interval was unrestricted and subjects could move freely to their choice, and one in which they were restrained from moving until the stimulus interval had elapsed. Our results revealed a higher degree of precision for subjects in the free-moving group. By further decomposing choice and response time data with a drift diffusion model of decision making, we identified the source of this change to a shift in the response threshold for free-moving subjects. Analysis of movement parameters revealed that eventual choice could be determined by movement parameters (e.g. trajectory, force) before the response was made, and even before the interval had elapsed, and that the variability of these movements was lower in the unrestrained group. A further experiment (n=14) verified that these findings were not due to proximity to the target, counting strategies, bias, or movement length. Our findings suggest that perceptual timing may be instantiated within the motor system as an ongoing readout of timing judgment and confidence.

Among the new trends in technology that have emerged through the Industry 4.0, Cyber Physical Systems (CPS) and Internet of Things (IoT) are crucial for the real-time data acquisition. This data acquisition, together with its transformation in valuable information, are indispensable for the development of real-time indicators. Moreover, real-time indicators provide companies with a competitive advantage over the competition since they enhance the calculus and speed up the decision-making and failure detection. Our research highlights the advantages of real-time data acquisition for supply chains, developing indicators that would be impossible to achieve with traditional systems, improving the accuracy of the existing ones and enhancing the real-time decision-making. Moreover, it brings out the importance of integrating technologies 4.0 in industry, in this case, CPS and IoT, and establishes the main points for a future research agenda of this topic.

Situational awareness is a critical aspect of the decision-making process in emergency response and civil protection and requires the availability of up-to-date information on the current situation. In this context, the related research should not only encompass developing innovative single solutions for (real-time) data collection, but also on the aspect of transforming data into information so that the latter can be considered as a basis for action and decision making. Unmanned systems (UxV) as data acquisition platforms and autonomous or semi-autonomous measurement instruments have become attractive for many applications in emergency operations. This paper proposes a multipurpose situational awareness platform by exploiting advanced on-board processing capabilities and efficient computer vision, image processing, and machine learning techniques. The main pillars of the proposed platform are: (1) a modular architecture that exploits unmanned aerial vehicle (UAV) and terrestrial assets; (2) deployment of on-board data capturing and processing; (3) provision of geolocalized object detection and tracking events; and (4) a user-friendly operational interface for standalone deployment and seamless integration with external systems. Experimental results are provided using RGB and thermal video datasets and applying novel object detection and tracking algorithms. The results show the utility and the potential of the proposed platform, and future directions for extension and optimization are presented.

BACKGROUND Coproduction of care involves patients and families partnering with their clinicians and care teams, with the premise that each brings their own perspective, knowledge, and expertise, as well as their own values, goals, and preferences to the partnership. Dashboards can display meaningful patient and clinical data to assess how a patient is doing and inform shared decision making. Increasing communication between patients and care teams is particularly important for children with chronic conditions, such as juvenile idiopathic arthritis (JIA), which is the most common, chronic rheumatic condition of childhood, and is associated with increased pain, decreased function, and decreased quality of life. OBJECTIVE We aimed to design a dashboard prototype for use in coproducing care for JIA patients. We evaluated the context use and needs of end users, obtained consensus on the necessary dashboard data elements, and constructed display prototypes to inform meaningful discussions for coproduction. METHODS A human-centered design approach involving parents, patients, clinicians, and care team members was used to develop a dashboard to support coproduction of care in four diverse ambulatory pediatric rheumatology clinics across the United States. We engaged a multidisciplinary team (n=18) of patients/parents, clinicians, nurses, and staff during an in-person kick-off meeting, followed by bi-weekly meetings. We also leveraged advisory panels. Teams mapped workflows and patient journeys, created personas, and developed dashboard sketches. Final necessary dashboard components were determined using Delphi consensus voting. Low-tech dashboard testing was completed during clinic visits, and visual display prototypes were iterated using PDSA methodology. Patients and providers were surveyed about their experiences. RESULTS Teams achieved consensus on what data matters most at point-of-care to support JIA patients, families, and clinicians partnering together to make the best possible decisions for better health. Notable themes included: the right data, in the right place, at the right time; data in once for multiple purposes; patient and family self-management components; and opportunity for education and increased transparency. A final set of 11 dashboard data elements were identified which include patient-reported outcomes, clinical data, and medications. Important design considerations include incorporation of real-time data, clearly labeled graphs, and vertical orientation to facilitate review and discussion. Prototype paper testing with 36 patients/families yielded positive feedback about the dashboard’s usefulness during clinic discussions, helped to talk about what mattered most, and informed healthcare decision making. CONCLUSIONS Our study developed a dashboard prototype that displays patient-reported and clinical data over time, along with medications, that can be used during a clinic visit to support meaningful conversations and shared decision making between JIA patients/families and their clinicians and care teams.

During multijoint limb movements such as reaching, rotational forces arise at one joint due to the motions of limb segments about other joints. We report the results of three experiments in which we assessed the extent to which control signals to muscles are adjusted to counteract these “interaction torques.” Human subjects performed single- and multijoint pointing movements involving shoulder and elbow motion, and movement parameters related to the magnitude and direction of interaction torques were manipulated systematically. We examined electromyographic (EMG) activity of shoulder and elbow muscles and, specifically, the relationship between EMG activity and joint interaction torque. A first set of experiments examined single-joint movements. During both single-joint elbow ( experiment 1) and shoulder ( experiment 2) movements, phasic EMG activity was observed in muscles spanning the stationary joint (shoulder muscles in experiment 1 and elbow muscles in experiment 2). This muscle activity preceded movement and varied in amplitude with the magnitude of upcoming interaction torque (the load resulting from motion of the nonstationary limb segment). In a third experiment, subjects performed multijoint movements involving simultaneous motion at the shoulder and elbow. Movement amplitude and velocity at one joint were held constant, while the direction of movement about the other joint was varied. When the direction of elbow motion was varied (flexion vs. extension) and shoulder kinematics were held constant, EMG activity in shoulder muscles varied depending on the direction of elbow motion (and hence the sign of the interaction torque arising at the shoulder). Similarly, EMG activity in elbow muscles varied depending on the direction of shoulder motion for movements in which elbow kinematics were held constant. The results from all three experiments support the idea that central control signals to muscles are adjusted, in a predictive manner, to compensate for interaction torques—loads arising at one joint that depend on motion about other joints.

Phenomenological Exploration

This paper is a phenomenological exploration into the true nature of musical time. Drawing on the thought of Henri Bergson, Vladimir Jankelevitch, and contemporary philosophers of music, I propose that the nature of musical time lies within the performer and that its existence is parallel to that of the ordinary lived time of the empirical universe. We experience musical time as "mobile" (Bergson's terminology) and as a phenomenon of passing. A musician's ability to play music "in time" is governed by what I refer to as his "internal musical biological clock." However, as music is an art form that is typically performed in a group, a musician's relationship must be an intersubjective relationship where the performers' experience of time is forced by a synchronization of their internal musical biological clocks.

Background: Procedural sedation is required for multiple short duration procedures outside of the operating rooms especially in radiology and endoscopy suites. Intravenous anesthetic agent with rapid recovery profile is desirable in such circumstances. This study aims to compare two regimens of intravenous anesthetic agents. Aim: To compare the mean recovery time of propofol and midazolam with propofol alone for sedation in endoscopic retrograde cholangiopancreatography. Study Design: Randomized controlled trial. Settings: Department of Anesthesia, Shalamar Hospital, Lahore. Study Duration: June 2017 to December 2017. Methods: A total of 70 adult patients aged 20-60 years undergoing ERCP under sedation were included. Patients were given a combination of propofol and midazolam in group A while propofol alone was given in group B. After procedure, pts were transferred to recovery room and were followed for assessment of recovery time. Data were analyzed in SPSS vr 21, Independent t-test was applied & p-value ≤0.05 was considered statistically significant. Results: Significant difference was found in mean recovery time amongst both the groups. Mean recovery time in Group A (propofol and midazolam) was 19.29±4.50 minutes while in Group B (propofol alone) was 26.66±3.70 minutes showing statistically significant result with p-value = 0.0001. Conclusion: We conclude that mean recovery time with propofol plus midazolam is shorter as compared to propofol alone for sedation in ERCP. Keywords: Propofol, midazolam, sedation outside operation theatre.

Modern society has various needs such as education, research, cultural advancement, information, spiritual and ideological pursuits, pastime and recreation. Society has founded various institutions to serve these needs, among them the library occupies a prominent place; the library is able to meet all of them in equal measure. The public library is the local centre of information making all kinds of knowledge and information made available to its users. The public library, the local gateway to knowledge, provides a basic condition for lifelong learning, independent decision making and cultural development of the individual and social group. A public library as enunciated in the UNESCO Manifesto (1994) is expected to play the libraries role in three main areas like information, education and culture. The aim of this chapter is to provide an overview of how the public libraries support and guides the digital and modern world.

The Rich

In the early 2000s, no framework within which to investigate the biology of aesthetics had been articulated. The author believes that a componential framework, as was common in cognitive psychology, applied to neuroaesthetics made sense. Such frameworks were commonly applied to complex cognitive domains, such as in language, emotion processing, or visual processing research. As such, the author proposes a “box and arrow” model which incorporated levels of visual processing, emotions, attention, and decision-making. The advantage of such a framework is that specific experiments could be placed in the context of testing hypotheses of parts of a larger system deployed for aesthetic processing. The framework has held up well over the years, although the author believes he did not sufficiently emphasize the role of the motor system and the rich contribution of semantics in aesthetic experiences.

Safety Investment

Safety is the premise of efficiency and effectiveness in the port operation. Safety investment is becoming a vital part of port operation in current era in order to overcome different types of hazards the port operation exposed to. This paper aims to improve the safety level of port operation through analyzing its influencing factors and exploring the interactions between the safety investment and system risk level. By analyzing the key factors affecting the port operation and their mutual relationship within a man–machine–environment–management system, a decision-making model of safety investment in port enterprise was established by system dynamics (SD). An illustration example and a sensitivity analysis were carried out to justify and validate the proposed model. The results show that increasing the total safety investment of port enterprises, improving the safety management investment on personnel, and strengthening the implementation effect of investment can improve the degree of port security to a certain extent. The strength of the proposed work is its practical application in current scenarios using real time data and the ability to provide a baseline approach for port enterprises to formulate safety investment strategy.
