UNDERSTANDING THE NATURE OF THE SECONDARY TASK 2022 - Rushika De Bruin, Larissa K. Barber - PSYCHOLOGICAL REPORTS This project explored social evaluations of electronic multitasking during work meetings, including factors that may affect whether it is seen as a counterproductive meeting behavior. We used an experimental vignette design to test whether social evaluations (norm violating, agency, and communalism) of a hypothetical coworker's electronic multitasking differed by whether the secondary task was relevant to the meeting (Study 1; N = 274) or ambiguous (Study 2; N = 188). Observers evaluated task-irrelevant multitasking as more of a norm violation and less communal compared to task-relevant multitasking, and work-related tasks were evaluated as more agentic than nonwork-related tasks. Ambiguous tasks were also rated as more agentic than task-irrelevant multitasking. Taken together, our results show that the nature of the secondary task reduces negative perceptions of coworkers' electronic multitasking behavior during meetings. However, electronic multitasking for any purpose, even if relevant, was generally judged negatively consistent with expectations for a counterproductive meeting behavior.

Barber - PSYCHOLOGICAL REPORTS INTERPERSONAL EMOTION REGULATION AND PSYCHOLOGICAL DISTRESS: WHAT IS THE FUNCTION OF NEGATIVE MOOD REGULATION EXPECTANCIES IN THIS RELATIONSHIP? 2022 - Elcin Ray-Yol, Ayse Altan-Atalay - PSYCHOLOGICAL REPORTS Individuals' tendency to use their interactions with others in the management of their own emotions is called Interpersonal Emotion Regulation (IER). Limited studies have explored the association between IER and psychological distress with none focusing on the role of mediating variables in this relationship. The current study aims to explore the role of negative mood regulation expectancies (NMRE), which is defined as one's confidence in the effectiveness of their coping skills while dealing with difficult emotions, as a possible mechanism underlying the association between IER and psychological distress. The data were collected from 204 (164 women) Turkish speaking individuals whose age ranges between 18 and 32 (M = 22.78, SD = 3.21). The participants completed measures of IER, NMRE and psychological distress. The results have indicated that NMRE has a significant mediating role in the relationship of Soothing dimension of IER with psychological distress. The present findings highlighted the maladaptive function of Soothing as an IER strategy in addition to shedding light on the important role of NMRE in this relationship.

Focus groups were conducted to gain understanding of the experiences and perspectives of youth at-risk who were currently receiving services from a community-based agency in a small city in the Western United States. Participants discussed acquiring life skills through agency programming including social skills and coping/self-regulation skills. Participants also reported a positive culture of the agency, expressing feelings of safety, trust and supportive relationships. Community-based programming may be in a pivotal position to provide services and supports that act as buffering protection against the effects of toxic stress.

Helm, Roxanna Dehaghani, 等 3 人 - MODERN LAW REVIEW When a defendant pleads guilty to a criminal charge against them their conviction may be justified on the basis of autonomy rather than accuracy. In this context, autonomy can make the difference between a legitimate conviction and the breach of fundamental rights. However, autonomy in this context is not clearly defined. This article argues, based on philosophical conceptions of autonomy and empirical realities, that true autonomy is an ideal rather than a practical reality. It considers the level of autonomy necessary to legitimise a criminal conviction via plea, and suggests that current conceptions of autonomy are inadequate since they rely on a formalistic autonomy 'myth', presuming autonomy in the absence of threats. An analysis drawing on original empirical data from two studies demonstrates how autonomy may be being depleted to unacceptable levels in the current system. The article concludes by presenting reform proposals. JUSTICEGUILTY PLEASCRIMINAL PROCEDURELAWHUMAN RIGHTSVULNERABILITYENGLANDAUTONOMYVULNERABILITYCONSENTEMPIRICAL LAWRIGHTSTRIAL 2022 - Rebecca K.

The effect is even more striking in Hawaii, which has been one of the most popular tourist destinations in the United States since the 1950s. While the state government's early reaction has resulted in a decrease in COVID cases in this state, travel restrictions established in response to the pandemic have wreaked havoc on the state's tourist economy. To quantitatively measure this impact, this paper investigates the nexus between the international tourist arrivals, COVID-19 spread, and air quality in Hawaii. Using the daily data from March 2020 to August 2020, the study employs the robust methodology comprising Wavelet coherence, partial and multiple Wavelet coherence methods. The empirical results reveal a significant coherence between international tourists, COVID-19 cases, and air quality at different time-frequency compositions.

Mohammed, Mohammed A. Qasim - ENERGIES Multilevel inverters (MLI) consist of a wide range of power converters. They have many designs and have been introduced with different circuit topologies such as neutral point clamped, diode clamped, cascaded H-bridges, and flying capacitors. Some of these MLIs have disadvantages, including design complexity, size, and losses due to the large number of switching devices required when they produce many output voltage levels. They are also bulky in size and may require several DC power sources. This paper presents a review of the various topologies of single-phase T-Type MLIs (T-MLIs). These MLIs are used to convert DC power from renewable energy sources (RES)" into AC with a near-sine waveform and low total harmonic distortion (THD). Simple and complex MLI designs are discussed. The major types of modulation techniques are discussed, including sinusoidal pulse width modulation (SPWM), selective harmonic elimination (SHE), and preprogrammed PWM. Various methods of output voltage control are taken into consideration as well. The aim of this comprehensive survey is to identify T-MLIs for researchers and those interested in the power conversion field, as well as to discuss the many topologies, identifying designs with superior characteristics that can be efficiently implemented with RESs to obtain better AC voltage with enhanced power quality.

Mohammed, Mohammed A. Qasim - ENERGIES OPTIMAL POWER FLOW TECHNIQUE FOR DISTRIBUTION SYSTEM CONSIDERING DISTRIBUTED ENERGY RESOURCES (DER) 2022 - Adolfo Blengini Neto, Maria Beatriz Barbosa, 等 5 人 - ENERGIES Modern electric power systems consist of large-scale, highly complex interconnected systems projected to match the intense demand growth for electrical energy. This involves the decision of generation, transmission, and distribution of resources at different time horizons. They also face challenges in incorporating new forms of generation, distributed generations, which are located close to consumer centers, and new loads such as electric vehicles. Traditionally, the nonlinear Newton-Raphson optimization method is used to support operational decisions in such systems, known as Optimal Power Flow (OPF). Although OPF is one of the most practically important and well-researched sub-fields of constrained nonlinear optimization and has a rich history of research, it faces the convergence difficulties associated with all problems represented using non-linear power flow constraints. The proposal is to present an approach in a software component in cloud Application Programming Interface (API) format, with alternative modeling of the electrical optimization problem as a non-linear objective function and representing electric network constraints modeled through both current and voltage Kirchhoff linear equations. This representation overcomes the non-linearity of the OPF problem considering Distributed Energy Resources (DER). The robustness, scalability, and availability of the method are tested on the IEEE-34 bus system with several modifications to accommodate the DER testing under conditions and in radial or meshed distribution systems under different load scenarios.

However, there are still some issues with natural gas engines retrofitted from 10 to 15 L diesel engines, which is a valuable medium-term goal for the automotive industry. In this work, the effect of intake port structure on the performance of a spark-ignited heavy-duty natural gas engine was investigated by multidimensional numerical simulations. A newly designed intake port was proposed, with strengthened in-cylinder turbulent kinetic energy and homogeneous air-fuel mixtures. Bench tests show that the proposed intake port has impressive thermal efficiency, cycle variation, and acceptable emissions performance. The effective thermal efficiency improves from 41.0% to 41.4%, and the cycle variation is 36% lower than traditional schemes. However, with the accelerated flame propagation, the in-cylinder temperature and NOx emission of the mixed-flow port increase while the CO emission decreases. In summary, a proper balance of in-cylinder swirl and tumble flow can significantly affect the economy and stability of natural gas engines. The proposed structure solves the inherent problems of slow natural gas flame propagation and harmful cyclic variations.

In this study, the soft computing technique of PV-DSTATCOM control based on the variable leaky least mean square (VLLMS) algorithm is modified to incorporate both reduced sensor and switch current limiting schemes. DSTATCOM is predominantly introduced to improve current related power quality issues by providing non-real power (i.e., the reactive and harmonic component) of the load demand. However, during uncertain increase in the non-real power requirement at the load end due to sudden change in the load demand or any other transient conditions, the non-real current injected by the DSTATCOM may increase to a level which is beyond the current handling capacity of the DSTATCOM switches. As a consequence, the switches may become permanently damaged and, subsequently, the performance of the DSTATCOM will deteriorate. Hence, the current through the VSI switches can be limited by controlling the amount of non-real power flow from the DSTATCOM. During this transient or high current condition, the control transits from power quality improvement mode to protection mode. As a result, unity power factor operation at P.C.C (common point of coupling) is compromised for that period or few cycles of transient condition. Moreover, the efficient operation of any control demands proper information about the current and the voltage of the system, which are determined by sensors. However, the faults in these sensors may deteriorate the controller performance and degrade the system efficacy. Therefore, to mitigate this issue, the numbers of measurement units are reduced i.e., the measurement of current in only two phases for load as well as grid, and the measurement of line voltages using two voltage sensors instead of three sensors for each phase. The reduction of sensors is accomplished without compromising the controller efficiency. Further, the system is studied using MATLAB/Simulink under different condition of steady- state, varying solar irradiance, increasing load above rated capacity.

In meeting future demand and supply predictions, much emphasis should be given to both energy consumption and the level of inter-factor and inter-fuel substitution possibilities. Specifically, future outcomes for energy demand are more valid when production models contemplate substitution elasticity occurring during the period. To analyze the potential for little reliance on fossil fuels and diminish CO2Es, the present research has examined the potential for the substitution of energy and non-energy factors (i.e., natural gas, electricity, petroleum, labor, and capital) by using translog productions function over the period between 1986-2019. The ridge regression method is applied to evade the multicollinearity issue in the data. The model analyzes the output elasticity, substitution elasticity, technical progress, and carbon emission scenarios. The results show that the output elasticities are growing, presenting that the contribution of all factors adds to economic growth. The inputs between capital-petroleum, capital-electricity, labor-electricity, capital-natural gas, and natural gas-electricity are extreme substitutes. These substitutes are increasing capital growth and production sizes. The relative difference in technical progress shows a small positive change between 3-7% with convergence evident. Lastly, the investment scenarios under 5% and 10% investment in petroleum reduction are evidence that the CO2Es would reduce by 7.5 Mt and 10.43 Mt under scenario 1 and 7.0 Mt and 10.9 Mt under scenario 2. The results have broader suggestions for energy-conserving policies, particularly under the China-Pakistan Economic Corridor.
