Alteration in neural oscillatory activity and phase‐amplitude coupling after sleep deprivation: Evidence for impairment and compensation effects

SummaryInsufficient sleep can significantly affect vigilance and increase slow‐wave electroencephalographic power as homeostatic sleep pressure accumulates. Phase‐amplitude coupling is involved in regulating the spatiotemporal integration of physiological processes. This study aimed to examine the functional associations of resting‐state electroencephalographic power and delta/theta‐gamma phase‐amplitude coupling from the prefrontal cortex (PFC) to posterior regions with vigilance performance after sleep deprivation. Forty‐six healthy adults underwent 24‐hr sleep deprivation with resting‐state electroencephalographic recordings, and vigilant attention was measured using the Psychomotor Vigilance Task. Power spectral and phase‐amplitude coupling analyses were conducted, and correlation analysis was utilized to reveal the relationship between electroencephalographic patterns and changes in vigilance resulting from sleep deprivation. Sleep deprivation significantly declined vigilance performance, accompanied by increased resting‐state electroencephalographic power in all bands and delta/theta‐gamma phase‐amplitude coupling. The increased theta activity in centro‐parieto‐occipital areas significantly correlated with decreased mean and slowest response speed. Conversely, the increased delta‐low gamma and theta‐high gamma phase‐amplitude couplings negatively correlated with the deceleration of the fastest Psychomotor Vigilance Task reaction times. These findings suggest that sleep deprivation affects vigilance by altering electroencephalographic spectral power and information communication across frequency bands in different brain regions. The distinct effects of increased theta power and delta/theta‐gamma phase‐amplitude coupling might reflect the impairment and compensation of sleep deprivation on vigilance performance, respectively.

SP-SAT: DEVELOPMENT OF AN EDUCATIONAL SATELLITE

n Bolivia, as in several other Latin American nations, there is a growing trend of burgeoning space projects and a rising interest among young students in the aerospace domain. Consequently, there arises an imperative to cultivate a new generation of space professionals. However, the exorbitant costs associated with the equipment utilized in these projects render them inaccessible to a vast majority of inter- ested students, including CubeSat kits, educational satellites, satellite kits, among others. Consequently, alternatives like educational sat- ellites have emerged to simulate the satellite design, construction, testing, launch, and operation processes on a scale conducive to student involvement. The primary challenge faced by students lies in integrating the essential subsystems of a satellite, encompassing power supply, sensors, and communication systems, within the confines of limited space. Considering this, the design and construction of an educational satellite with its respective signal reception equipment was developed. The equipment designed and manufactured is a low-cost one so that universities and educational centers could acquire it. This equipment educational kit is called SP-SAT (Space Program — educational satellite kit). This real satellite simulator offers a wide variety of educational activities. The kit’s equipment is distributed in two systems: 1) Space Segment, which consists of an Onboard Computer (OBC), Electrical Power System (EPS), Communications System (COMM), Experiment Plate (PYL), Complete PLA plastic structure (3D printed), rods, bolts, and nuts. 2) Ground segment: This segment includes all the equipment that is part of the ground station, which will receive data from the satellite.

Flexible resource demand response scheduling strategy under 5G-V2X

Electric vehicles (EV) and 5 G base stations, functioning as flexible load resources, contribute significantly to the provision of ample reserve capacity for the power grid. The emergence of 5 G Vehicle-to-Everything (V2X) technology has fostered a coupling between EV and base stations, further enhancing their roles within the power grid. Building upon this foundation, this paper proposes a scheduling strategy for demand response in flexibility resources under the 5 G-V2X framework. Initially, the dispatchable load of EV is examined in conjunction with the traffic network. Subsequently, we consider the communication power consumption resulting from the connected vehicle model, enabling us to devise path planning and charging navigation strategies for EV. Lastly, we establish a scheduling decision model that aims to minimize both the operation costs of base stations and the variance in grid load. The simulation is validated using real-world road conditions in the primary urban area of a city. The findings illustrate that the proposed dispatching strategy not only achieves a mutually beneficial outcome for EV users and aggregators, without disrupting EV charging and discharging processes, but also enhances the capability of demand response, thereby ensuring reliable grid operation.

Infiltrating Functional English for Technical Students with the Concomitant of Project Transcripts: A Paradigm in Education

A powerful communication strategy plays a key role in professional settings, all the while demonstrating its ability to garner admiration and respect. Over time, Language is an ever-evolving system from a usage standpoint. Despite several existing methods, the quality of knowledge of technical communication remains a persistent challenge for non-native speakers at the instructional level. This paper explores how engineering students can acquire an understanding of and practice functional technical English by preparing micro and macro projects. This study examined 200 student projects, each comprising 20 pages and approximately 300 lines. These projects serve for statistical analysis and are evaluated based on specific five test areas, such as usage of tense, change of voice, concord, vocabulary, and connectors. The two groups (EG & CG) were offered pretest and post-test. The result of the analysis is interpreted with the help of line graphs that assess the comparability of the two groups. Remedial measures with sequence flow charts were suggested to the participants that served the purpose of mending their deficient areas, which, if believed, would enhance their career progression. This method would assist tertiary-level students in breaking language barriers, enabling them to express their ideas in writing and speaking more effectively using technical language, especially in the ordinary usage of technical means to explain complex technical principles. A language is language, when reflected in the correct sense with the ability to use it functionally rather than learning it for years.

An Online Home Energy Management System using Q-Learning and Deep Q-Learning

The users of home energy management systems schedule their real-time energy consumption thanks to advancements in communication technology and smart metering infrastructures. In this paper, a data-driven strategy is proposed, which is an Online Home Energy Management System (ON-HEM) that uses reinforcement learning algorithms (Q-Learning and Deep Q-Learning) to control the optimal energy consumption of a smart home system. The proposed system comprises power resources (grid, photovoltaic), communication networks, and appliances with their agents classified into four groups: deferrable, non-deferrable, power level controllable, and electric vehicle. The system reduces electricity costs and high peak demands while considering the cost of user dissatisfaction with real-life data. Simulations are performed on the proposed ON-HEM considering different pricing approaches (Real Time Pricing and Time of Use Pricing) with Q-Learning and Deep Q-Learning (DQL) algorithms using PyCharm Professional Edition software. The findings demonstrate both the superiority of DQL over Q-Learning and the efficiency of the proposed ON-HEM in decreasing high peak demand, electricity costs, and customer dissatisfaction costs. The efficiency and dependability of the proposed system were verified by utilizing simulation-based findings with real-life data using IBM SPSS Statistics software.

The four frames of leadership and motivating language theory: Version 2.0

Purpose The purpose of this conceptual paper is to increase the clarity and application of the original model and integration table. Specifically, the intent was to increase clarity by highlighting elements left out of the original article (sentence frames), adding additional information on the medium of leadership practice through the addition of Bolman and Deal's leadership lessons, and improving the flow and structure of leader steps as leaders move across the model in the leader sequence of events. Finally, the model was tweaked to adjust the political frame across both direction-giving and empathetic language based on participant feedback and a literature review. Design/methodology/approach The approach of this conceptual paper is to continue the evolution of the integration of the Four-Frames and Motivating Language Theory (MLT) first presented in DLO in 2019 using updated literature from Bolman and Deal (2019, 2021) and feedback from real-world implementation of the contents from the original article. Findings The findings of this conceptual paper are in two forms. First, the Version 2.0 integration model illustrates greater clarity and an improved sequence for implementation by leaders to address the pressing issues they face. Second, the illustration of the sentence frames and their evolution from the original article (2019) to the current paper highlights the power and integration of the Four-Frames and Motivating Language Theory regarding their versatility and utilization as a critical thinking and teaching tool for leaders and organizations. Practical implications For practitioners, this conceptual paper provides additional information on how to implement the Four-Frames as leaders through the power and influence of leadership communication and action. Originality/value The value of the Version 2.0 integrated model continues to leverage the combination of the Four Frames and Motivating Language Theory, which is still unique in the research. This evolution of the integration creates greater clarity in terms of understanding and utilizing leadership, connecting and sequencing the Four-Frames and MLT together, and applying the Four-Frame(s) accurately. This article continues to extend the field of Motivating Language Theory and addresses a gap in the work of the Four Frames – communication.

Conflict Recovery in Socialist Utopia: A Critical Analysis of Vietnam's Postwar Reconstruction Policies Through a Visual Interpretation of 1976–1986 Propaganda Posters

The Vietnam War left a newly reunified Vietnam with innumerable challenges following the fall of Saigon in April 1975. Through an interpretive analytical approach using propaganda posters as the visual data source, this study examines how the Communist Party of Vietnam and the Vietnamese government disseminated economic, political, diplomatic, military, and social policies to the public in order to rally support for the ambitious goal of rebuilding the country as an industrialized socialist nation. In doing so, this study shows how a national reconstruction discourse could be modalized in textual, visual, and symbolic spaces to maximize its persuasiveness in conflict recovery efforts. Ultimately, this study demonstrates that while recovery is the utmost goal of governments following the end of conflicts, basing it on a specific ideology without careful examination of contextual factors can be deleterious and even calamitous. Propaganda posters can serve as a powerful communication tool for policy makers, but poorly aligned campaigns can be counterproductive.

Hybrid framework of fatigue: connecting motivational control and computational moderators to gamma oscillations.

There is a need to develop a comprehensive account of time-on-task fatigue effects on performance (i.e., the vigilance decrement) to increase predictive accuracy. We address this need by integrating three independent accounts into a novel hybrid framework. This framework unites (1) a motivational system balancing goal and comfort drives as described by an influential cognitive-energetic theory with (2) accumulating microlapses from a recent computational model of fatigue, and (3) frontal gamma oscillations indexing fluctuations in motivational control. Moreover, the hybrid framework formally links brief lapses (occurring over milliseconds) to the dynamics of the motivational system at a temporal scale not otherwise described in the fatigue literature. EEG and behavioral data was collected from a brief vigilance task. High frequency gamma oscillations were assayed, indexing effortful controlled processes with motivation as a latent factor. Binned and single-trial gamma power was evaluated for changes in real- and lagged-time and correlated with behavior. Functional connectivity analyses assessed the directionality of gamma power in frontal-parietal communication across time-on-task. As a high-resolution representation of latent motivation, gamma power was scaled by fatigue moderators in two computational models. Microlapses modulated transitions from an effortful controlled state to a minimal-effort default state. The hybrid models were compared to a computational microlapse-only model for goodness-of-fit with simulated data. Findings suggested real-time high gamma power exhibited properties consistent with effortful motivational control. However, gamma power failed to correlate with increases in response times over time, indicating electrophysiology and behavior relations are insufficient in capturing the full range of fatigue effects. Directional connectivity affirmed the dominance of frontal gamma activity in controlled processes in the frontal-parietal network. Parameterizing high frontal gamma power, as an index of fluctuating relative motivational control, produced results that are as accurate or superior to a previous microlapse-only computational model. The hybrid framework views fatigue as a function of a energetical motivational system, managing the trade-space between controlled processes and competing wellbeing needs. Two gamma computational models provided compelling and parsimonious support for this framework, which can potentially be applied to fatigue intervention technologies and related effectiveness measures.

The Power of Internal Communication for Environmental Sustainability in Promoting Employee’s Pro-Environmental Behaviors

ABSTRACT Using the situational theory of problem solving (STOPS) as a theoretical framework, this study examines how internal communication regarding environmental initiatives can promote pro-environmental behaviors (PEBs) of employees at work, thereby helping achieve corporations’ sustainability goals. Results of an online survey of 443 employees in the U.S. suggested that internal communication helps to increase employees’ problem and involvement recognition of their employer’s sustainability initiatives, while decreasing their constraint recognition. When employees are situationally motivated by their organizations’ communication efforts, they actively engage in communicative behaviors and PEBs at work. Theoretical and practical implications for internal public relations are discussed.

Political Discourse Analysis of Donald Trump’s Rhetoric: A Linguistic Study of Cognition and Discursivity

To elucidate the deliberate use of Islamophobia in the political sphere, this study carefully examines Donald Trump's presidential campaign speeches using political discourse analysis (PDA). Trump’s Islamophobic position in political discourse has sparked a global discussion. His divisive political language during the 2016 elections contributed to an overall rise in incidents showing hatred for Muslims in the America by painting a poor picture of the Muslim world. The present study employs the theoretical framework of Van Dijk (1998) to examine the socio-political contexts of the discourse: participants’ insight (their goals, relevant knowledge and their belief system), group organization, power dynamics, as well as favourable and unfavourable perceptions of “us” against “them”. The purpose of the work is to highlight the processes by which Islamophobia is created, propagated, and normalised in public discourse. The nature of the current investigation involves heterogeneous techniques. It analyzes the text using PDA methods. Additionally, it computes word frequency to determine the proportion of positive to negative terms in Donald Trump's political speech. The analysis reveals that political leaders use language as a tool to serve their own political ends. This study focusses on understanding the complex interplay between language, power, and ideology in contemporary political communication. By shedding light on the pervasive influence of Islamophobia as a political strategy, it underscores the imperative of critically engaging with political discourse to challenge hegemonic narratives, and to foster all-inclusive and democratic societies. Political leaders frequently employ language as a weapon to further their agendas. This research work highlights the necessity of critically interacting with political discourse to challenge dominant narratives and promote inclusive and democratic societies by bringing to light the pervasive influence of Islamophobia as a political strategy.
