Using Improv to Enhance Communication Skills Practice (SA520)

•Recognize the commonalities of improvisation and healthcare communication and discuss ways these techniques are adaptable to different settings.•Experiment with variations in tone of voice, physicality, and word choices and reflect on the impact.•Restate frustrations as priorities and values. Have you been asked to give grand rounds on communication skills and want to incorporate a meaningful exercise to enhance your didactic? Have you been facilitating communication skills training and feel bored with the current curriculum? Or maybe you are looking for a different perspective on the communication skills you are using. Many palliative care providers are not only relied upon for their excellent communication skills with patients, families and colleagues, they are asked to teach communication skills to others as well. Self and social awareness are valuable skills for identifying opportunities to find words that will resonate with patients in the present moment. However, as clinicians are being asked to do more with less and in shorter periods of time, opportunities for mindful, reflective practice can be harder to find. Idealized communication sessions that limit the number of participants and require hours of time are not always possible. Adapted improv techniques to practice communication skills, even in large group settings, allows for a safe and supportive environment that fosters participant spontaneity and honesty while raising awareness about what we communicate, whether it is intentional or not. In this session, presenters who are using improvisation in a variety of settings will quickly review the main tenants of improvisation and discuss how these tenants enhance clinical encounters and apply in healthcare communication. Participants will experience a selected group of improv exercises, discuss their relevance in communication skills training and hypothesize how these activities can be adapted to a variety of audiences. If you’ve been looking for ways to bring meaningful communication skills training to audiences from 10-1000 participants in a short amount of time, this session is for you. We promise that “being funny” is NOT a core tenant of improv and not required to attend this session.

City-Wide Eco-Routing Navigation Considering Vehicular Communication Impacts.

Intelligent Transportation Systems (ITSs) utilize Vehicular Ad-hoc Networks (VANETs) to collect, disseminate, and share data with the Traffic Management Center (TMC) and different actuators. Consequently, packet drop and delay in VANETs can significantly impact ITS performance. Feedback-based eco-routing (FB-ECO) is a promising ITS technology, which is expected to reduce vehicle fuel/energy consumption and pollutant emissions by routing drivers through the most environmentally friendly routes. To compute these routes, the FB-ECO utilizes VANET communication to update link costs in real-time, based on the experiences of other vehicles in the system. In this paper, we study the impact of vehicular communication on FB-ECO navigation performance in a large-scale real network with realistic calibrated traffic demand data. We conduct this study at different market penetration rates and different congestion levels. We start by conducting a sensitivity analysis of the market penetration rate on the FB-ECO system performance, and its network-wide impacts considering ideal communication. Subsequently, we study the impact of the communication network on system performance for different market penetration levels, considering the communication system. The results demonstrate that, for market penetration levels less than 30%, the eco-routing system performs adequately in both the ideal and realistic communication scenarios. It also shows that, for realistic communication, increasing the market penetration rate results in a network-wide degradation of the system performance.

Wide-Area Damping Control using Reduced Copy under Intermittent Observation: A Novel Performance Measure

Insight into the application of observer-driven reduced copy (ORC) to deal with data packet dropout during wide-area oscillation damping control through wind farms (WFs) is developed. The ORC technique tries to emulate the behavior of the power system by using the information of the nominal dynamics under intermittent observation. This brief presents a direct performance measure for ORC. To that end, a standard lemma relating the bound on the norm of the integral over the product of two functions is presented, which is proven using Holder’s inequality. Based on the lemma, an expression is derived for the bound on the norm within an inter-sample interval for difference between the power system states in presence of data dropout and that under ideal communication. Such a bound, when evaluated in a relative sense, would be useful for system operators to perform online contingency screening and ranking from damping performance standpoint without running prohibitively expensive time-domain simulations. In addition, such a bound is also derived for the conventional feedback control (CFC). The data dropout is modeled using the Gilbert-Elliott model. The analytical results are validated using time-domain simulation of a 16-machine, 5-area New England-New York system with two doubly fed induction generator-based WFs.

Q-Learning-Based Damping Control of Wide-Area Power Systems Under Cyber Uncertainties

The installation of phasor measurement units brings about system-wide synchronized real-time measurements, which makes advanced closed-loop control of wide-area power systems (WAPSs) possible. In addition to uncertainties with the physical system, network imperfections are also critical for control performance and even stability of the system. This paper targets at wide-area damping control of WAPS under both physical and cyber uncertainties. The cyber uncertainties addressed in this paper include both communication delay and package dropout. First, a linearized WAPS model is developed with considerations of random control signal arrivals. Then, a ${\boldsymbol Q}$ -learning-based control algorithm is designed to learn the optimal control under both physical and cyber uncertainties. Finally, to further counteract the communication uncertainties between the control center and actuators, a novel control law is designed based on the statistical analysis to make the long-term control performance approach that under ideal communications. The designed control algorithm is tested with both simplified linear model and detailed nonlinear model of WAPSs. Simulation results demonstrate the effectiveness of the designed algorithm.

Project-based learning in subtitling field: a description of a learning experience

Audiovisual Translation or subtitling is one of alternative in learning a foreign language. It is a new educational tool and ideas. It offers variety and flexibility, contextualizes linguistic items, provides exposure to cultural and nonverbal elements, and is closer to natural ideal communication than the written or oral modes. In this article, we provide the learning experiences design implemented in subtitling course taught in the sixth semester of the Degree in English Language Education Program of IAIN Surakarta, in Indonesia, and we examine the tasks and technique implementation in the classroom. Specifically, we pay attention more on Project-Based Learning (PBL) and review from colleague in the subtitling course. The discussion of both students’ performances and their reactions to the new learning experiences is the main results.

An Adaptive Switched Control Approach to Heterogeneous Platooning With Intervehicle Communication Losses

The advances in distributed intervehicle communication networks have stimulated a fruitful line of research in cooperative adaptive cruise control (CACC). In CACC, individual vehicles, grouped into platoons, must automatically adjust their own speed using on-board sensors and communication with the preceding vehicle so as to maintain a safe intervehicle distance. However, a crucial limitation of the state of the art of this control scheme is that the string stability of the platoon can be proven only when the vehicles in the platoon have identical driveline dynamics and perfect engine performance (homogeneous platoon), and possibly an ideal communication channel. This paper proposes a novel CACC strategy that overcomes the homogeneity assumption and that is able to adapt its action and achieve string stability even for uncertain heterogeneous platoons. Furthermore, in order to handle the inevitable communication losses, we formulate an extended average dwell-time framework and design an adaptive switched control strategy, which activates an augmented CACC or an augmented adaptive cruise control strategy depending on communication reliability. Stability is proven analytically and simulations are conducted to validate the theoretical analysis.

On the Performance of Distributed and Cloud-Based Demand Response in Smart Grid

By locally solving an optimization problem and broadcasting an update message over the underlying communication infrastructure, demand response program based on the distributed optimization model encourage all users to participate in the program. However, some challenging issues present themselves, such as the existence of an ideal communication network, especially, when utilizing wireless communication, and the effects of communication channel properties, like the bit error rate, on the overall performance of the demand response program. To address the issues, this paper first defines a cloud-based demand response (CDR) model, which is implemented as a two-tier cloud computing platform. Then a communication model is proposed to evaluate the communication performance of both the CDR and distributed demand response models. This paper shows that when users are finely clustered, the channel bit error rate is high and the user datagram protocol (UDP) is leveraged to broadcast the update messages, making the optimal solution unachievable. Contradictory to UDP, the transmission control protocol will be caught up with a higher bandwidth and increase the delay in the convergence time. Finally, this paper presents a cost-effectiveness analysis which confirms that achieving higher demand response performance incurs a higher communication cost.

Thinking parliamentary technology assessment politically: Exploring the link between democratic policy making and parliamentary TA

This paper aims to clarify the political nature of parliamentary technology assessment (PTA) by reflecting on PTA's relationship with democratic policy making. This issue is raised in a political climate that is regularly portrayed as a ‘post-truth era’ and influenced by the rise of radical right populism. Democratic policy making is described in terms of problem structuring that depends on powering, scientific puzzling, participation and deliberation. Regulative democratic ideals, like political equality, truth, citizen participation, and ideal communication, are identified that drive these processes. These concepts are used to clarify the political nature of PTA in two ways. First the kind of political support for PTA within countries where PTA is or was institutionalized is explored. A typology of seven levels of political support to PTA is discerned. These degrees of support depend on whether PTA is performed by MPs or by TA experts, and to what extent MPs allow PTA to play a role in the scientific puzzling process and/or organize participation-cum-deliberation processes. To further clarify the political nature of PTA, three political attitudes towards the regulative democratic ideals are distinguished: affirmative, indifferent, and adverse. It is shown that processes of powering, scientific puzzling and participation-cum-deliberation can be used in ways that are guided by regulative democratic ideals (affirmative), ignore those ideals (indifferent) or undermine them (adverse). In political contexts in which indifferent or adverse attitudes prevail political support for PTA of any kind is very unlikely. It is argued that PTA can strengthen democratic policy making, when it fully acknowledges the political nature, and strengths and weaknesses of both scientific puzzling and participation-cum-deliberation. In this way PTA can connect to democratic forms of populism, and is well-positioned to counteract anti-scientism, anti-intellectualism, and anti-democratic forms of populism.

Distributed Noise-Resilient Networked Synchrony of Active Distribution Systems

This paper proposes a distributed noise resilient control technique for voltage and frequency synchronization in inverter-based ac microgrids. Existing cooperative control techniques assume ideal communication among inverters. The effect of additive noise in communication links among inverters, and between the reference signal and inverters, on the synchronization process, is studied. Distributed least mean-square solutions estimate the reference set points, and a local least mean-square algorithm estimates neighboring inverter frequencies and voltages. The efficacy of the proposed solution, for an islanded microgrid test system under the additive noise in reference communication links and links connecting neighboring inverters, is evaluated for a modified IEEE 34-bus feeder system. An upper bound for the noise-induced deviation in the consensus parameter is analytically derived and verified by the simulated testbed.

Design of Intelligent Vehicle Monitoring System Based on ZigBee

In order to meet the needs of real-time positioning and remote dispatching of vehicle, this paper designs a ZigBee-based embedded vehicle terminal and the corresponding ZigBee-GPRS information communication network in hardware and software. With LPC2366 processor and CC2430 RF chip as core, the vehicle terminal acquires the vehicle‘s status in cycle, and completes the vehicle monitoring and scheduling by transmitting data to communication nodes by ZigBee and passing the data on to the monitoring center by GPRS. This vehicle terminal is characterized by small size, low energy consumption and ideal communication distance, which makes the monitoring center effectively monitor and schedule the vehicles.

Quadrotor Formation Inversion Control Method Based on Unit Quaternion

Abstract In this paper, the formation control problem of quadrotor is studied under ideal communication condition. The quadrotor has a complex mathematical model. First, the unit quaternion method is used to describe its dynamic model and kinematic model. It is decomposed into two independent subsystems of position and attitude. The tracking error model is established by introducing the error between the ture trajectory and the desired trajectory. And then appointing a member of formation as a pilot, formation members get the geometric center position as the desired trajectory through the consistency algorithm. The back-stepping method is used to design the time-varying feedback control law for each four-rotor, so that the formation is stabilized. Finally, the effectiveness of the control method is verified by simulation experiments.

Efficient k-out-of-n oblivious transfer scheme with the ideal communication cost

In this paper, we propose a two-round k-out-of-n oblivious transfer scheme with the minimum communication cost. In our proposed scheme, the messages sent by the receiver R to the sender S consist of only three elements, which is independent of n and k, while the messages from S to R are (n+1) elements when the sender holds n secrets. Our scheme features a nice property of universal parameter, where the system parameter can be used by all senders and receivers. The proposed k-out-of-n oblivious transfer scheme is the most efficient two-round scheme in terms of the number of messages transferred between two communicating parties in known constructions. The scheme preserves the privacy of receiver's choice and sender's security.

Fair Resource Allocation in Self-Organizing Heterogeneous Networks With Imperfect Connections

Interference management by controlling the transmission powers is crucial for unveiling the potential of heterogeneous networks. Power allocation has mostly been investigated using ideal communication links, where it is generally assumed that information can be relayed perfectly between base stations. The impact of delays and time-outs during communication is not well understood. We propose a model with nonideal links and a power adjustment algorithm for heterogeneous networks. Contrary to the power allocation approaches in the literature, channel state information is not required for power adjustment. The convergence properties of the proposed algorithm are investigated using tools from switched system theory and it is shown to converge to the max–min solution even with nonideal communication links. The simulation results are in agreement with the theoretical analysis.

A Power Allocation Algorithm For Multi-Tier Cellular Networks With Heterogeneous QoS and Imperfect Channel Considerations

Interference management via resource allocation under the quality of service (QoS) provisions is a crucial challenge for next-generation cellular networks. The task becomes more problematic due to emerging services and applications with non-homogeneous QoS requirements. The resource allocation problem has mostly been investigated using ideal communication links, where it is generally assumed that information can be relayed perfectly between base stations (BSs). The impact of delays and time-outs at communication links during coordination of BSs is not well understood. Furthermore, it is generally assumed that perfect channel state information is available at BSs which may not always be possible due to large channel feedback delays or estimation errors. In this paper, we propose a power adjustment algorithm for heterogeneous networks which considers varying QoS requirements of users. Contrary to the power allocation approaches in the literature, channel state information is not required for power adjustment. The performance of the algorithm is evaluated both analytically and numerically under a setup with non-ideal communication links. The theoretical analysis unveils that the proposed algorithm achieves optimum power allocation with respect to the QoS requirements of users. The numerical results are not only in agreement with theoretical analysis, but also exhibits significant improvement in terms of overall network performance.

Inserción del concepto de mito en las descripciones del invernadero del hôtel Saccard en "La Curée" de Émile Zola

En este ensayo abordamos una temática recurrente en aquellos textos de Zola en los que el jardín desempeña un papel primordial: la inserción del concepto de mito. Con este propósito efectuamos un análisis minucioso del discurso poético de las dos descripciones del invernadero del palacete Saccard en La Curée de Émile Zola, que nos ayudará a desvelar una dimensión profunda del pensamiento zoliano: su búsqueda de elementos mitológicos y simbólicos camuflados en el jardín, lugar de comunicación ideal con la naturaleza. Dicha búsqueda nos invita a una reflexión sobre los efectos de la civilización científico-técnica, centrada en la razón, que no por ello es capaz de eliminar la necesidad de lo oculto y lo fantástico.

Further, Pharmacotherapy Literacy is going to be defined as a remarkable subject in the literature. This is a descriptive study illustrating the concepts with the literature.

The Clinical and Medicolegal Implications of Radiology Results Communication

Multiple guidelines and legal precedents have established the radiologist's duty to inform clinicians directly of critical findings, or findings that will greatly impact patient health in a timely manner [1]. While the number one cause for radiology malpractice cases is misdiagnosis, the literature shows a growing portion of lawsuits surrounding breakdowns in communication between radiologists and ordering providers [2,3]. As such, a review of guidelines related to the communication of imaging results is warranted. We will describe and provide our perspective on results communication as well as attempt to further define ideal communication practices in healthcare scenarios that fall outside of normal cases.

Optimization-Based AC Microgrid Synchronization

This paper casts the synchronization phenomena in inverter-based ac microgrids as an optimization problem solved using alternating direction method of multipliers (ADMM). Existing cooperative control techniques are based on the standard voting protocols in multiagent systems, and assume ideal communication among inverters. Alternatively, this paper presents a recursive algorithm to restore synchronization in voltage and frequency using ADMM, which results in a more robust secondary control even in the presence of noise. The performance of the control algorithm, for an islanded microgrid test system with additive noise in communication links broadcasting reference signals and communication links connecting neighboring inverters, is evaluated for a modified IEEE 34-bus feeder system. An upper bound for the deviation due to communication noise from the reference set point is analytically derived and verified by the simulated microgrid test system.

Exploiting spatial degrees of freedom for high data rate ultrasound communication with implantable devices

We propose and demonstrate an ultrasonic communication link using spatial degrees of freedom to increase data rates for deeply implantable medical devices. Low attenuation and millimeter wavelengths make ultrasound an ideal communication medium for miniaturized low-power implants. While a small spectral bandwidth has drastically limited achievable data rates in conventional ultrasonic implants, a large spatial bandwidth can be exploited by using multiple transducers in a multiple-input/multiple-output system to provide spatial multiplexing gain without additional power, larger bandwidth, or complicated packaging. We experimentally verify the communication link in mineral oil with a transmitter and a receiver 5 cm apart, each housing two custom-designed mm-sized piezoelectric transducers operating at the same frequency. Two streams of data modulated with quadrature phase-shift keying at 125 kbps are simultaneously transmitted and received on both channels, effectively doubling the data rate to 250 kbps with a measured bit error rate below 10−4. We also evaluate the performance and robustness of the channel separation network by testing the communication link after introducing position offsets. These results demonstrate the potential of spatial multiplexing to enable more complex implant applications requiring higher data rates.
