Supportive communication climate in the self-development of Generation Z
Authors: Purbaningrum Dwi , Sudarmanti Rini
Published: November 2022

Generation-Z has become a popular topic in mass media, due to their development amidst the growing online lifestyle of our society. Born between 1996-2010, the internet has become part of their development, as it slowly grew into our society. Generation-Z are the true digital native. They have grown accustomed to using their handphone all day long, doing various activities with it. Such custom is enhanced by the Covid-19 pandemic which reduced, significantly, the possibility of a direct physical contact with other members of the society since March 2020. The contact also includes their learning and working process—where schools and offices alike were forced to take their operations online. This research used the qualitative-descriptive approach to get a natural depiction of the informants, and a study case to get a holistic data from the respondents, a group of Generation-Z. The purpose of this research is to find out how Generation-Z interprets the online learning situation. Using Modern Theories of Learning and symbolic interactionism, it was found that informants grew up in a supportive communication climate while learning from home. Informants are also more productive as they could study while working, interning in several places. This finding concluded that Gen-Z could use their online situation to develop themselves.

Published: November 2022

In many areas of business, technological innovation is critical. The ability to use technology to transform organisations is now a requirement in all industries. Nonetheless, technological acceptance has a significant impact on overall corporate performance. Mobile applications are becoming more popular all over the world. As a result, the goal of this research is to look into the technology acceptance model in order to improve customer service in mobile applications. A questionnaire survey was used to collect data from mobile users in Abu Dhabi Municipality. The Partial Least Squares-Structural Equation Modelling (PLS-SEM) technique, aided by SmartPLS software, was used to analyse 396 completed questionnaire forms. The study's findings indicate that perceived usefulness, perceived ease of use, and attitude all have a significant impact on the intention to use technology. The role of intention to use as a moderator is also confirmed, as is the moderating effect of user experience. Furthermore, statistical evidence supports the role of user experience as a moderator in the customer satisfactionexperience. The study's findings give marketing managers and academics a much stronger foundation for recommending CSE strategies. As a result, telecom operators must go above and beyond to improve PU, PEOU, and attitude, as well as develop strategies, inorder to achieve a higher level of CSE.
The Performance Comparison of the SiC and Si Mosfets Used in the 3-Phase Brushless DC Motor Drives for Electric Vehicles
Authors: ÇETİN Emrah , SEVİM Erkan
Published: November 2022

This study was carried out to compare the Si and SiC MOSFETs in the market used on motor driver circuits. A motor driver circuit is designed to run the brushless DC motors. Thanks to the semiconductors used in the driver circuit, the motor receives current as desired. While performing this task, the MOSFETs get hot and lose power. This situation changes according to the material structure used inside the MOSFETs. Hence, it is planned to compare Si MOSFETs that have been in the market for a long time and SiC MOSFETs that have been used recently under different loads and different temperatures circumstances. Si and SiC MOSFETs are placed in the motor driver circuit, which has the same structure in the simulation environment. The operation of the motor under no load and on different mechanical loads has been analysed. In these cases, the response of the MOSFETs to temperature changes was also analysed by changing the cooling temperature. As a result of the study, SiC MOSFETs were less heated and less power loss was observed than Si MOSFETs. It has been observed that when the mechanical load is high, the switching speed of Si MOSFETs decreases despite the speed of SiC MOSFETs is not affected. As a result of this study, it has been observed that SiC MOSFETs used in the motor driver circuit work more efficiently than Si MOSFETs for electric vehicles.

Authors: TAHA Zeedan , AYDIN Kadir
Published: November 2022

Electric vehicles offer a promising solution to solving environmental problems related to air pollution. The typical powertrain design of an electric vehicle includes a relatively high-speed-low-torque electric motor integrated with some mechanical system to transmit the output mechanical energy to the wheels, such as the gearbox, transmission and differential. Different drivetrain configurations with single, double and quad electric motors can be used in electric vehicles. In this study, it is aimed to compare the effects of different powertrain configurations on the acceleration performance, range and energy consumption of the electric vehicle. Single, dual and quad motor electric vehicle powertrain systems were simulated with MATLAB Simulink according to the New European Driving Cycle (NEDC). The Volvo XC40 Recharge electric car was used as the reference vehicle with the same vehicle characteristics, battery type/capacity and the same total power output by changing only the electric motor powertrain configurations. It has been determined that quadruple electric motor powertrain configuration has lower energy consumption, longer range and better acceleration performance than the single and double electric motor powertrain configurations.

Islamic Rural Banking (populer as BPRS in Indonesia) is a kind of banking which conducts finance and loan especially in rural area. This monetary institution focuses to main function as a bank which gives the service to small and micro enterprises and based on Islamic principles in their operational system. By providing the fund to productive sectors, the economics will be tough and more competitive. That is why, this rural bank is also called “community bank”. In supporting financial inclusion -a concept where each person has a full access to monetary service, with competitive cost, convenience and prestige- the contribution of these community banks have really existed. On the other hand, the optimalization of this contribution process constraints to many things that covers internal and external problem. The finding of research recommends some strategies to improve the role of community bank in supporting financial inclusion in rural area, such as: reinforcement in regulation’s strategy, socialization’s strategy, competition’s strategy and human resource’s strategy

Postmodern

Published: November 2022

Kata postmodern secara harfiah berarti “ setelah modern”, istilah “modern”yang berarti zaman baru, berasal dari bahasa latin modernus, yang telah digunakan sejak abad ke-5 untuk menunjuk batas antara era kekuasaan agama kristen dan era paganisme romawi (Smart 1990). Istilah ini kemudian berkembang menjadi beberapa istilah yang menunjukan pada suatu sejarah setelah era abad pertengahan. Beberapa istilah tersebut adalah modernitas, modernisasi, dan modernisme.Postmodernisme pada mulanya muncul dibidang arsitektur sekitar tahun 1950, yangmana menunjuk pada gaya, corak, dan bentuk bangunan yang mencoba melepaskan diri dari kaidahkaidah arsitek modern.Dalam bidang sastra budaya, modern ditandai denganadanya kecenderungan untuk mengakhiri cerita dengan penyelesaian tertutup yang justru dicurigai postmodern dan dianggap simplistic. Disamping itu sastra modern cenderung mencari satu tatanan atau kaidah yang bisa berlaku umum, sementara sastra postmodern justru sangat menghargai pluralism. Mikhail Bakhtin kritikus sastra Rusia menyatakan bahwa sastra postmodern sentrifugal, penuh variasi, eksperimental, fragmentaris, skeptic dan antiotoritasIstilah dari modernitas (modernity) diartikan sebagai kondisi sosial budaya masyarakat modern. Modernitas ini menggambarkan hubungan antara masa sekarang dan masa lalu serta sebagian konsep sejarah ada yang berbeda dimana modernitas lebih modern dibandingkan dengan masa-masa sebelumnya. Modernitas inilah yang merupakan era yang lebih dewasa dan lebih mendasar dalam aspek-aspek rasio, religi dan estetika di banding dengan masa-masa sebelumnya.Pada saat itu berbagai teori lahir pemikiran postmodernisme dalam wilayah sosiologi yang mengkaji tentang postmodernisme sehingga menemukan bentuk dan kematangannya pada tahun 1960-1980-an. Ada beberapa tokoh pemikiran teori sosial postmodern diantaranya adalah Jean Francois Lyotard, Michel Foucault, Jacques Derrida, Jean Baudrillard, dan Friedrich Jameson. Postmodern masih dapat berkembang hingga saat ini harus kita akui bahwa puncak berkembannya postmodern terjadi pada tahun 1980-an.

Seismic Architecture of the Lithosphere-Asthenosphere System in the Western United States from a Joint Inversion of Body- and Surface-wave Observations: Distribution of Partial Melt in the Upper Mantle
Authors: Byrnes Joseph , Gaherty James , Hopper Emily
Published: November 2022

Quantitative evaluation of the physical state of the upper mantle, including mapping temperature variations and the possible distribution of partial melt, requires accurately characterizing absolute seismic velocities near seismic discontinuities. We present a joint inversion for absolute but discontinuous models of shear-wave velocity (Vs) using 4 types of data: Rayleigh wave phases velocities, P-to-s receiver functions, S-to-p receiver functions, and Pn velocities. Application to the western United States clarifies where upper mantle discontinuities are lithosphere-asthenosphere boundaries (LAB) or mid-lithospheric discontinuities (MLD). Values of Vs below 4 km/s are observed below the LAB over much of the Basin and Range and below the edges of the Colorado Plateau; the current generation of experimentally based models for shear-wave velocity in the mantle cannot explain such low Vs without invoking the presence of melt. Large gradients of Vs below the LAB also require a gradient in melt-fraction. Nearly all volcanism of Pleistocene or younger age occurred where we infer the presence of melt below the LAB. Only the ultrapotassic Leucite Hills in the Wyoming Craton lie above an MLD. Here, the seismic constraints allow for the melting of phlogopite below the MLD.
Shared Mental Representations Underlie Metaphorical Sound Concepts

Published: November 2022

Communication between sound and music experts is based on the shared understanding of a metaphorical vocabulary derived from other sensory modalities. Yet, the impact of sound expertise on the mental representation of these sound concepts remains blurry. To address this issue, we investigated the acoustic portraits of four metaphorical sound concepts (brightness, warmth, roundness, and roughness) in three groups of participants (sound engineers, conductors, and non-experts). Participants (N=24) rated a corpus of orchestral instrument sounds (N=520) using Best-Worst Scaling. With this data-driven method, we sorted the sound corpus for each concept and population. We compared the population ratings and ran machine learning algorithms to unveil the acoustic portraits of each concept. Overall, the results revealed that sound engineers were the most consistent. We found that roughness is widely shared while brightness is expertise dependent. The frequent use of brightness by expert populations suggests that its meaning got specified through sound expertise. As for roundness and warmth, it seems that the importance of pitch and noise in their acoustic definition is the key to distinguishing them. These results provide crucial information on the mental representations of a metaphorical vocabulary of sound and whether it is shared or refined by sound expertise.
Biology, society, or choice: How do non-experts interpret explanations of behaviour?
Authors: Nettle Daniel , Frankenhuis Willem , Panchanathan Karthik
Published: November 2022

Explanations for human behaviour can be framed in many different ways, from the social-structural context to the individual motivation down to the neurobiological implementation. We know comparatively little about how people interpret these explanatory framings, and what they infer when one framing rather than another is made salient. In four experiments, UK general-population volunteers read vignettes describing the same behaviour, but using different explanatory framings. In study 1, we found that participants grouped explanatory framings into ‘biological’, ‘psychological’ and ‘sociocultural’ clusters. Explanations with different framings were often seen as incompatible with one another, especially when one belonged to the ‘biological’ cluster and the other did not. In study 2, we found that adopting a particular explanatory framing produced spontaneous inferences. Specifically, psychological framings led participants to assume the behaviour was malleable, and biological framings led them to assume it was not. In studies 3a and 3b, we found that the choice of explanatory framing can affect people’s assumptions about effective interventions. For example, presenting a biological framing increased people’s conviction that interventions like drugs would be effective, and decreased their conviction that psychological or socio-political interventions would be effective. These results illuminate the intuitive psychology of explanations, and also potential pitfalls in scientific communication. Using a particular explanatory framing will often generate inferences in the audience – about what other factors are not causally important, how easy it is to change the behaviour, and what kinds of remedies are worth considering – that the communicator may not have anticipated and might not intend.
Associations between self-reported rheumatoid arthritis, rheumatoid factor positivity and structural brain phenotypes in the UK Biobank

Published: November 2022

Objectives: The literature on structural brain health in people with rheumatoid arthritis (RA) is very limited. Our aim was to investigate whether there are any brain phenotype differences between people that are positive rheumatoid factor (RF+) and/or people that self-reported RA, compared with people who are not RF+ and do not report RA (‘healthy controls’). Methods: We tested for cross-sectional associations between RA and/or RF+ vs. several MRI brain volume variables in the UK Biobank (n=37, 379 participants, out of which 432 reported RA and 1,833 were RF+). We adjusted for age, sex, and assessment centre in the partially adjusted models, while in the fully adjusted models we additionally controlled for deprivation, smoking and cardiometabolic conditions. Results: Those that self-reported RA were more likely to have increased log white matter hyperintensity volumes (WMH standardised β= 0.08, 95% CI= 0.021; 0.14, p<0.01), and smaller volumes of the amygdala (β=-0.09, 95% CI= -0.16; -0.02, p<0.01) in the partially adjusted analyses. In the fully adjusted model RA remained significantly associated with amygdala volume (β=-0.09, 95% CI= -0.16; -0.02, p<0.01). No significant associations with RF+ status were found. Conclusion: Our study provides evidence for differences in structural brain volumes that are known to be related to psychological and cognitive health in those with vs. without RA. Since previous literature suggests a potential role for the amygdala in pain modulation and mental health, and an increased risk for stroke associated with WMH, we believe that our findings may be of clinical importance to people with RA. Further research is necessary to confirm these associations and asses their functional implications.
Individual- and Family-Level Associations between Child Psychopathology and Parenting
Authors: Aitken Madison , Perquier Florence , Haltigan John D. , Wang Li , Andrade Brendan F. , Battaglia Marco , szatmari peter , Georgiades Katholiki
Published: November 2022

Parenting can protect against the development of, or increase risk for, child psychopathology; however, it is unclear if parenting is related to psychopathology symptoms in a specific domain, or to broad liability for psychopathology. Parenting differs between and within families, and both overall family-level parenting and the specific parenting a child receives may be important in estimating transdiagnostic associations with psychopathology. Data come from a cross-sectional epidemiological sample (N = 10,605 children ages 4-17 in 6,434 households). Parents rated child internalizing and externalizing symptoms and their parenting towards each child. General and specific (internalizing, externalizing) factors, derived from a bifactor model, were regressed on parenting using multilevel modelling. Less warmth and more harsh/inconsistent parenting in the family, and toward a child specifically, were associated with higher general psychopathology and specific externalizing problems. Unexpectedly, more warmth in the family, and toward a child specifically, was associated with higher specific internalizing problems in 4-11 year-olds (not 12-17 year-olds). Less warmth and more harsh/inconsistent parenting are broad correlates of child psychopathology. Harsh/inconsistent parenting, is also related to specific externalizing problems. Parents may behave more warmly when their younger children have specific internalizing problems, net of overall psychopathology.
Meta-Analysis of the Relationship between Frontal EEG Asymmetry and Approach/Avoidance Motivation
Authors: Garrison Katie , Schmeichel Brandon , Baldwin Cassandra
Published: November 2022

One of the most fundamental constructs in the study of motivation is motivational direction, or the urge to approach versus avoid. Motivational direction may be mediated in part by neural activity in the frontal cortex. Specifically, individual differences in resting frontal asymmetry in the electroencephalogram (EEG) have been conceptualized as a trait-like disposition that reflects basic motivational and affective tendencies. Greater relative left frontal activity has been associated with trait approach motivation and positive affect, whereas greater relative right frontal activity has been associated with trait avoidance motivation and negative affect. The current meta-analysis estimated the relationships between resting frontal EEG asymmetry and traits related to approach and avoidance. We also tested between two prominent models of frontal asymmetry, namely the affective valence model and the motivational direction model. Across 112 studies (N = 7,473) we found significant relationships consistent with predictions: Trait approach motivation and positive affect related to relatively greater left frontal asymmetry at rest (r = 0.076), whereas trait avoidance motivation and negative affect related to relatively greater right frontal asymmetry at rest (r = -0.066). Findings regarding trait anger—a negative affect associated with approach motivation—tended to support to the motivational direction model over the valence model. We discuss the implications for future research on frontal asymmetry as a neurobiological trait underlying motivational direction.
Neurophysiological and Emotional Influences on Team Communication and Metacognitive Cyber Situational Awareness During a Cyber Engineering Exercise
Authors: Ask Torvald F. , Knox Benjamin J. , Lugo Ricardo , Helgetun Ivar , Sütterlin Stefan
Published: November 2022

Background: Cyber operations unfold at superhuman speeds where cyber defense decisions are based on human-to-human communication aiming to achieve a shared cyber situational awareness. The recently proposed Orient, Locate, Bridge (OLB) model suggests a three-phase metacognitive approach for successful communication of cyber situational awareness for good cyber defense decision-making. Successful OLB execution implies applying cognitive control to coordinate self-referential and externally directed cognitive processes. In the brain, this is dependent on the frontoparietal control network and its connectivity to the default mode network. Emotional reactions may increase default mode network activity and reduce attention allocation to analytical processes resulting in sub-optimal decision-making. Vagal tone is an indicator of activity in the dorsolateral prefrontal node of the frontoparietal control network and is associated with functional connectivity between the frontoparietal control network and the default mode network. Aim: The aim of the present study was to assess whether indicators of neural activity relevant to the processes outlined by the OLB model were related to outcomes hypothesized by the model. Methods: Cyber cadets (N = 36) enrolled in a 3-day cyber engineering exercise organized by the Norwegian Defense Cyber Academy participated in the study. Differences in prospective metacognitive judgments of cyber situational awareness, communication demands, and mood were compared between cyber cadets with high and low vagal tone. Vagal tone was measured at rest prior to the exercise. Affective states, communication demands, cyber situational awareness, and metacognitive accuracy were measured on each day of the exercise. Results: We found that cyber cadets with higher vagal tone had better metacognitive judgments of cyber situational awareness, imposed fewer communication demands on their teams, and had more neutral moods compared to cyber cadets with lower vagal tone. Conclusion: These findings provide neuroergonomic support for the OLB model and suggest that it may be useful in education and training. Future studies should assess the effect of OLB-ing as an intervention on communication and performance.
Measurement of the response inhibition network in a brief battery of tasks: Introducing an assessment of reactive and proactive inhibition processes.
Authors: Beu Nathan , Burns Nicholas , Baetu Irina
Published: November 2022

Traditional response inhibition tasks are assumed to capture one’s ability to inhibit a response. This ability, however, requires a reactive process and a proactive process, post-error slowing (PES). Recent evidence shows that Stop-Signal Tasks (SSTs) measure the reactive process, and while the Sustained Attention to Response Task measures overall response inhibition, that measure is confounded by a proactive process. Since the diseases associated with response inhibition deficits often co-occur with symptoms that diminish the capacity for lengthy behavioural testing, and, since it is unknown to which process such decrements can be attributed and where in the brain these processes are generated, rapid and precise measurement of reactive and proactive processes is important. To address these issues, we administered a battery of four response inhibition tasks to healthy young adults (N = 123), two SSTs and two Go/No-Go tasks. In three tasks, we implemented adaptations to allow direct observation of proactive inhibition, reactive inhibition, and overall response inhibition. We introduce a novel cueing procedure to investigate the possibility of a predictive mechanism of proactive inhibition, arguing that slower response times on trials with a higher Stop/No-Go probability indicate predictive proactive inhibition. Based on these findings, we propose a novel demarcation to proactive inhibition: remedial proactive inhibition (PES), and predictive proactive inhibition. Additionally, we provide empirical support for a Bayesian adaptive staircase (Livesey & Livesey, 2016) that allows rapid convergence on estimates of reactive inhibition in SSTs in as few as 20 trials that are robust against potential predictive proactive inhibition confounds.

Published: November 2022

Multi-electrode APS has proven significant advantages with regard to spray rates, deposit efficiency and component life time. So far, three-cathode and three-anode spray guns have been established successfully in several industrial sectors where high spray rates are mandatory. Based on the successful three-anode plasma spray gun DELTA, the five-anode APS gun PENTA was developed to further increase productivity. With its gross power of up to 125 kW it allows very high spray rates and thus significantly reduced coating times. This paper focusses on the development of high spray rate parameter settings for producing oxide ceramic coatings. All coatings will be investigated with regard to their microstructures. Furthermore, economical benefits of the five anode technology will be highlighted.
Practical Aspects of Suspension Plasma Spray for Thermal Barrier Coating on Potential Gas Turbine Components
Authors: Ma X. , Ruggiero P.
Published: November 2022

Suspension plasma spraying (SPS) process has attracted extensive effort and interest as a method to produce fine-structured and functional coatings. In particular, thermal barrier coating (TBC) applied by SPS process has gained increasing interest due to its potential for producing coatings that provide superior thermal protection of gas turbine hot-section components as compared to conventional APS-TBC and even EB-PVD TBC. The unique columnar architecture and nano- and submicron sized grains in a SPS-TBC coatings demonstrate some advantages in thermal shock durability, low thermal conductivity, and high-temperature sintering resistance. This work addresses some practical aspects of using the SPS process for TBC applications before it becomes a reliable industry method. The spray capability and applicability of SPS to achieve uniform thickness and microstructure on curved substrates was evaluated in designed spray trials to simulate industrial parts with complex configurations. The performance of SPS-TBCs in erosion, free falling ballistic impact, and indentation loading tests was evaluated to simulate SPS-TBC performance in turbine service conditions. The behaviors of SPS-TBCs in those tests were correlated to key test factors including grit incident angles, impact object sizes, indentation head shapes, and coating surface curvatures. Finally, a turbine blade was coated and sectioned to verify SPS sprayability in multiple critical sections. The SPS trials and test results demonstrate that SPS is promising for innovative TBCs, but some challenges need to be addressed before it becomes an economical and reliable industrial process, especially for gas turbine components.

Gadolinium zirconate (GZ) is considered as a promising top coat candidate for high temperature (>1200 °C) thermal barrier coating (TBC) applications. Suspension plasma spray (SPS) technique has shown the capability to generate a wide range of microstructures which includes the more desirable columnar microstructure. In this study, GZ single layer TBCs were deposited by axial SPS process. The variable parameters include the standoff distance, solid load content of the suspension and input power. The cross section and top surface of the as sprayed TBCs were analyzed by SEM. The phase content in the as sprayed TBCs was analyzed by XRD. The porosity content of the as sprayed TBCs was measured using image analysis. In the SEM analysis, it was observed that a lower solid load content in the suspension favored the formation of a columnar microstructure. Additionally, at lower solid load content, increase in standoff distance resulted in columnar microstructure with high porosity content in the TBC. However, with higher solid content suspension and alteration of input power, only a dense vertical cracked microstructure can be obtained.

This study was focused on the biocidal efficacy on spores of copper alloy sheet and copper alloy coating at two different surface topographies. Endospores can remain viable in a dormant state for centuries. Our work compares the effectiveness of copper alloy coating and copper sheet metal in killing endospores. A twin-wire arc spray system was used for coating of stainless steel coupons. The feedstock was CuNiZn wire, the coating thickness was 400 µm. The copper alloy sheet metal had the same composition and is registered as antimicrobial by Environmental Protection Agency (US). Uncoated stainless steel coupons were used as controls in all experiments. The surface was polished to two roughness levels: Ra=3.5 µm and Ra=0.1 µm. The surface topography was analyzed by a stylus profilometer and 3D image analysis. EDS and FIB were used to characterize the elemental composition and structure of flower-like nanostructures and endospores. The results obtained in this study indicated that changes in Ra values of 0.1 and 3.5 µm had no significant impact on the biocidal activity of sheet metal and the coating on E. coli, S. epidermidis and B. subtilis. The coating was as effective as the EPA-certified sheet metal in the destruction of vegetative cells within 5 minutes. This study indicates that degradation of B. subtilis endospore begins within 2 hours after exposure to the coating. By day seven, only extensively degraded endospores and nanostructures were visible on both surfaces. Our results show that thermal spray copper alloy coatings were as effective as certified antimicrobial sheet metal in the destruction of endospores within hours; however, the coating was more effective in killing the endospores after one week of exposure.

In order to guarantee their protective function, thermal sprayings must be free from cracks, which expose the substrate surface to e.g. corrosive media. Cracks in thermal sprayings are usually formed because of tensile residual stresses. Most commonly, the crack occurrence is determined after the thermal spraying process by examination of metallographic cross-sections of the coating. Recent efforts focus on in situ monitoring of crack formation by means of acoustic emission analysis. However, the acoustic signals related to crack propagation can be absorbed by the noise of the thermal spraying process. In this work, a high-frequency impulse measurement technique was applied to separate different acoustic sources by visualizing the characteristic signal of crack formation via quasi-real-time Fourier analysis. The investigations were carried out on a twin wire arc spraying process, utilizing FeCrBSi as a coating material. The impact of the process parameters on the acoustic emission spectrum was studied. Acoustic emission analysis enables to obtain global and integral information on the formed cracks. The coating morphology as well as coating defects were inspected using light microscopy on metallographic cross-sections. Additionally, the resulting crack patterns were imaged in 3D by means of X-ray micro-tomography.
