Impact of Control Loops on the Passivity Properties of Grid-Forming Converters with Fault-Ride through Capability

Due to the increasing integration of renewable energy sources (RES) and a corresponding reduction of conventional generating units, there is nowadays a demand from the power-electronic converters to provide grid-forming properties through proper control of the converter systems. This paper aims to evaluate the impact of various control loops in a grid-forming control strategy equipped with a fault-ride through capability on the passivity properties of the converter system. Through the analysis of the frequency-dependent input admittance of the converter, the main factors affecting the passivity properties are identified. A simplified analytical model is derived in order to propose possible control modifications to enhance the system’s passivity at various frequencies of interest and the findings are validated through detailed time-domain simulations and experimental tests.
Deconstructing the Language of Accounting Textbooks to Make Power Relations Visible

The paper is motivated by the realization of the absent of critical engagement research problematizing the mainstream accounting worldview within accounting textbooks in the context of Indonesia. By doing so, this study uses the Thompson’s (1990) Schema of analyzing ideology to examine the content of popular introductory financial accounting (IFA) textbooks adopted by universities to reveal how, and the extent to which, the ideological status quo is reflected within these texts. This means the analysis tries to understand how ideological meaning is constructed within the textbooks. The analysis shows that the investigated textbooks portray accounting as an abstracted notion of a practical and calculative tool. Meanwhile, the ideological assumptions and socio-political and cultural background and conflict inherent in accounting are concealed and obscured. The textbooks have not scrutinized the concepts and measurement of accounting beyond employing a shareholder perspective. Consequently, the users’ attention is deflected from or glossed over the underlying ideological nature of the textbooks
Supervisor companionate love expression and elicited subordinate gratitude as moral-emotional facilitators of voice amid COVID-19

ABSTRACT Emerging research shows that moral emotions can promote individual prosocial behaviors and adaptation during adversity. Integrating Affective Events Theory (AET) with two functionalist theories of emotions (social functions of emotions and broaden-and-build theory of positive emotions), we extend this line of research by focusing on other-oriented moral emotions as facilitators of individuals’ adaptive behavior of voice during a major crisis. We conducted a four-wave survey study with 111 U.S. working adults during the early (acute) stage of the COVID-19 pandemic. Our path analyses in AMOS, coupled with PROCESS-aided analyses in SPSS, indicated that supervisors’ companionate love expression elicited gratitude in subordinates, particularly when subordinates perceived high uncertainty of the crisis, which, in turn, broadened subordinates’ in-role perceptions of, and promoted engagement in, voice behaviors. Our findings extend AET in meaningful ways and contribute to research on the moral emotions of companionate love and gratitude, stressing their value in managerial practice.
Exploring behaviour control and actual use of Massive Open Online Courses system management for education sustainability

The effect of innovation diffusion theory (IDT) activities on the adoption of Massive Open Online Courses (MOOCs) system management for education sustainability was investigated in this research. The research extended the Technology Acceptance Model (TAM) with IDT. Therefore, the aim of this study is to investigate the factors that influence business students' perceived behaviour control and actual use of MOOCs system management for education sustainability. Structural equation modeling (SEM) was used to evaluate the hypothesized relationships basis of data collected from 235 business students at Majmaah University. Business Students' feedback was classified into eight factors and analyzed to see how they perceived about their perceived behaviour control and how they used MOOCs system management for education sustainability. The results showed a strong link between perceived compatibility, relative advantage, and perceived enjoyment, as well as perceived ease of use and usefulness. Perceived usefulness and perceived ease of use influenced positively business Students' attitudes toward use MOOCs, perceived behaviour control, and actual use of MOOCs system management for education sustainability. From the results, perceived compatibility, relative advantage, and perceived enjoyment all have a positive and important effect on perceived ease of use and usefulness of MOOCs, according to the findings. Business students' attitudes toward MOOCs, perceived behaviour control, and actual MOOCs system management for education sustainability use are all positively influenced by perceived ease of use and perceived usefulness.
Jurassic to Early cretaceous sedimentary record: indications of Paleo-Pacific Plate subduction in Southeast China

ABSTRACT Plate subduction plays a decisive role in continental tectonics, and subduction history is closely connected to deformation and sedimentation in the overriding plate. When and how the Paleo-Pacific Plate subducted beneath Southeast China in the Mesozoic is debated. Here, we show that provenance data, including detrital composition point counts, palaeocurrent data, and detrital zircon U-Pb geochronology from basins in Southeast China, record the timing and process of Paleo-Pacific Plate subduction during the Jurassic and Earliest Cretaceous. The U-Pb dating of detrital zircons from Jurassic samples indicates that the sediments were transported from multiple sources, including intracratonic mountains, tectonic belts and the inferred active continental margin arc that resulted from Paleo-Pacific Plate subduction. The clastic composition and U-Pb dating of Early Cretaceous tuffs suggest that they were sourced from nearby magmatic rocks and the eastern inferred magmatic arc. Based on detrital zircon U-Pb dating, igneous rock isotope, sedimentary, and structural data, we infer that an active continental magmatic arc developed along the coast of Southeast China in the Early Jurassic to Early Cretaceous (~200 Ma-135 Ma). The westward subduction of the Paleo-Pacific Plate initiated in the Early Jurassic (~200 Ma) and continued to the Early Cretaceous (~135 Ma). Paleo-Pacific Plate subduction resulted in the uplift of the northern Wuyi Mountain region and eastern South China and controlled the provenance characteristics of the sedimentary basins in Southeast China during the Jurassic to Early Cretaceous.
Green human resource management and green organizational citizenship behavior: do green culture and green values matter?

PurposeDrawing on the Ability–Motivation–Opportunity (AMO) theory, this study aims to test the effect of green human resource management (G-HRM) on green organizational citizenship behavior (G-OCB) taking into consideration green culture as the mediator and green values as the moderator.Design/methodology/approachValid data from 240 entities collected in Taiwan were analyzed to test the five hypotheses. The valid data were analyzed using confirmatory factor model, correlation analysis, structural equation modeling and bootstrapping analysis.FindingsThe results for all relationships show significant associations. G-HRM is significantly associated with G-OCB and green culture, while green culture is significantly related to G-OCB. The mediating effect of green culture on the G-HRM-G-OCB relationship is significant. The moderating effect of green values on the green culture–G-OCB relationship is significant.Originality/valueThe originality of this study lies in being one of the first study in an advanced emerging economy utilizing the AMO theory.
Evoking gender distinctiveness threat in cisgender women lowers their support for gender-inclusive bathroom policies

Some cisgender women oppose policies granting transgender women access to women-only bathrooms. We examined whether this opposition stems from perceiving that transgender women threaten the distinctiveness of the social category “women” (gender distinctiveness threat). Cisgender women (N = 520) read about a state bill enabling transgender women to use women’s bathrooms. Participants further read that enacting the bill would mean their state officially believes that “transgender women are real women” or “transgender rights are human rights”; in the control condition, this information was omitted. Participants reported their support for the bill and level of gender distinctiveness threat. Cisgender women who read that the bill would imply their state believes transgender women are real women (vs. transgender rights are human rights) reported lower bill support, and this effect was mediated by distinctiveness threat. Perceived threat to the distinctiveness of womanhood may help explain cisgender women’s reluctance to include transgender women in women-only spaces.
A CONSTRUCTIVIST ANALYSIS OF THE IMPACT OF INDIA’S DOMESTIC IDENTITIES ON ITS NEIGHBOURHOOD POLICIES TOWARDS SOUTH ASIA

Domestic factors especially national identities of a Nation State influence its foreign policy by distinguishing that country’s perception of “self” from that of “others”. By employing the case study of India, this paper assesses the way India perceives its national identities and the resultant effects on its foreign policies towards South Asia. The paper assesses that in India, its peculiar political construct superimposed by British colonizers and multiple ethno-religious groups stacked together under a Hindutva-inspired political system serve as an aberration from the evolution of indexical “self” of different nationalities in that country. Accordingly, India’s national identity formation is premised on “exclusion” and it attempts to overcome this challenge through externalization of its internal problems towards neighbourhood.
On the determination of ionospheric electron density profiles using multi-frequency riometry

Abstract. Radio wave absorption in the ionosphere is a function of electron density, collision frequency, radio wave polarisation, magnetic field and radio wave frequency. Several studies have used multi-frequency measurements of cosmic radio noise absorption to determine electron density profiles. Using the framework of statistical inverse problems, we investigated if an electron density altitude profile can be determined by using multi-frequency, dual-polarisation measurements. It was found that the altitude profile cannot be uniquely determined from a complete measurement of radio wave absorption for all frequencies and two polarisation modes. This implies that accurate electron density profile measurements cannot be ascertained using multi-frequency riometer data alone, but that the reconstruction requires a strong additional a priori assumption of the electron density profile, such as a parameterised model for the ionisation source. Nevertheless, the spectral index of the absorption could be used to determine if there is a significant component of hard precipitation that ionises the lower part of the D region, but it is not possible to infer the altitude distribution uniquely with this technique alone.
Sewage sludge enhances tomato growth and improves fruit-yield quality by restoring soil fertility

Among the various disposal strategies for sewage sludge (SS), soil application is the most suitable. This study was conducted to evaluate soil amendment with SS (0, 10, 20, 30 and 40 g/kg) and its impact on soil fertility and tomato (Solanum lycopersicum L.) growth. The SS significantly improved the agromorphological attributes, the number of produced fruits, and the fruit biomass of tomato plants. The 30 g/kg application of SS led to the highest growth rate and fruit yield. Considering the fruits, the best safe enrichment of metal nutrients was recorded at 30 g/kg, with a significant increase in the micronutrient metals Mn, Zn, Ni, Cu, and Fe with 624, 193, 125, 70, and 32%, respectively, compared to the control. The SS amendment enhanced soil fertility, and heavy metals were within the permissible ranges for agricultural soils. Bioaccumulation factors (BFs) indicated that SS application induced the accumulation of most of the studied metals in the roots, and the BF values of Zn, Cu, Ni, and Pb were > 1. The current study concluded that recirculating SS nutrient components to agricultural soils could offer a valid solution for the sustainable management of this organic waste and enhance plant-crop productivity.
Temporal Variability and Predictability of Intense Cyclones in the Western and Eastern Mediterranean

Our understanding of the time variability of intense cyclones in the Mediterranean region is still lacking despite its importance for the long-term forecast of climate anomalies. This study examines the month-to-month variability and predictability of cyclones, the intensity of which exceeded the 75th percentile (intense cyclones) and the 95th percentile (extreme cyclones), over the Western and Eastern Mediterranean. The locations of cyclones were obtained by applying the method of M. Yu. Bardin on the 6-hourly 1000 hPa geopotential height data from the NCEP/NCAR reanalysis for the period 1951–2017 (67 years). It was shown that annual frequencies of cyclones were higher in the Western Mediterranean due to the contribution of spring and autumn; monthly averages were higher in the Eastern Mediterranean in December/January–March for intense/extreme cyclones. In the context of global warming, no linear trends significant at the 90% confidence level were found in the variability of intense and extreme cyclones, except for a positive trend in autumn extreme cyclones over the Eastern Mediterranean. The time series of cyclones in both parts of the Mediterranean were characterized by a pronounced interannual variability with a noticeable decadal modulation. According to spectral analysis, these interannual periods were multiples of 2–3 years corresponding to the main global teleconnection patterns. Seasonally, the most energy was concentrated in winter spectra; spring and autumn spectra had lower comparable magnitudes. The correlation analysis between the frequency of cyclones and the indices of the main atmospheric patterns showed that the main synchronous patterns for intense and extreme Mediterranean cyclones in September–April were the Mediterranean Oscillation (with the opposite signs for the Western and Eastern Mediterranean), Scandinavia pattern (positive correlation), and East Atlantic Oscillation (negative correlation). Additional important synchronous teleconnection patterns for some months were the Arctic Oscillation and East Atlantic/West Russia pattern for the Western Mediterranean, and the Polar/Eurasia pattern and Tropical Northern Hemisphere pattern for the Eastern Mediterranean. The outcome of this paper was the use of an artificial neural network model with inputs of global teleconnection indices both in the atmosphere and ocean to describe the temporal variability of the frequency of intense cyclones in the Western and Eastern Mediterranean. The predictability of intense cyclones was shown with the possibility of forecasts with a lead time of 0, 2, 4, and 6 months for the Western Mediterranean in October, January, February, April, and May, and for the Eastern Mediterranean in January, February, March, April, and May. One of the applications of this model may be in forecasting the evolution of the monthly frequency of cyclones with a lead time of 2 to 6 months.
A Compact Sequentially Rotated Circularly Polarized Dielectric Resonator Antenna Array

In this study, a compact 2 × 2 circularly polarized (CP) sequentially rotated (SR) dielectric resonator antenna (DRA) array operating in the IEEE 802.11a band is presented. To acquire the CP radiation, an elliptical slot (ES) was introduced to couple a rectangular dielectric resonator (RDR). The ES generates two resonant frequencies corresponding to the dominant even and odd modes. The SR feeder is made of four quarter-wavelength microstrip transformers to reduce the input impedance of the elements and, consequently, maximize the power transferred to each element. Experimental and simulation verifications were conducted on a 54 × 50 × 0.813 mm3 prototype to evaluate the performance of the proposed antenna array, which achieved a VSWR < −10 dB bandwidth of 1 GHz (5.1–6.05 GHz) and axial ratio (AR) < 3 dB of 0.95 GHz (5.1–5.85 GHz). The agreement between the simulated and measured results confirmed the validity of the proposed design.
Energy Efficiency: The Manufacturing Sector in Indonesia

Indonesia is involved in the global effort to alleviate the deterioration of the environment due to climate change. Given that the manufacturing industry accounts for the second-highest share of national energy consumption, efficiency energy in the industrial sector is crucial. This research examines which industrial subsector has to be prioritized to improve energy efficiency and what are the determinant factors that influence energy efficiency in Indonesia manufacturing. This study analyzes energy intensity as an approach to measure energy efficiency. Focusing on the 2010 - 2015 period, this research employs two methods, namely input-output and panel data regression analysis. The empirical finding shows that textiles and textile products; pulp, paper, paper products, printing, and publishing; and rubber and plastics sectors are the first priority subsectors that must implement green industry standards. The next priority is the subsectors at the second level but have no green industrial standards, namely electrical and optical equipment. Furthermore, there were four variables that statistically increase energy intensity, namely lagged energy intensity, technology intensity, lagged value added, and location of plant. However, other two variables, the price of electricity and company size, can reduce energy intensity.
Some heterogeneous structures in liquid crystals made of bent core molecules and their mixtures with rod-like molecules

ABSTRACT We present a broad overview of the heterogeneous structures observed in liquid crystals (LC) made of bent core (BC) molecules. In particular, nematic LCs are known to have clusters with 100s of BC molecules, and many compounds with moderate layer polarisation (P) exhibit stripes in the layers with divP distortion. Such stripes have been found in SmAPmod phase made of nontilted molecules, the B7 phase with tilted molecules and bilayer SmCgmod phase in which the BC molecules tilt with general orientation. We argue that all these phenomena arise from the conformational variety of the BC molecules, about 10–20% of which are in an excited state with a larger opening angle compared to the majority of ground state molecules with a smaller opening angle. We outline our theoretical results on these systems. We also analyse the structures found in the modulated LC phases induced in some binary mixtures of compounds made of BC and rod-like molecules. We end with some personal recollections about Sadashiva. Graphical abstract

This means that as many as 87% of farmers have a beef cattle farming business with moderate sustainability criteria and as many as 13% of farmers have a beef cattle farming business with very sustainable criteria (very sustainability).
A Relational Theory of Reputational Stability and Change

An ongoing discussion in organizational studies has focused on the path-dependent nature of organizational reputation. To date, however, there has been little explanation about when and why some constituents’ reputation judgments remain stable, whereas others are more prone to change. We contribute to this research by developing a relational theory of reputational stability and change. Our fundamental argument is that differences in constituent-organization relationships, as well as in the reputational communities that surround these relationships, affect the stability and change of reputation judgments. First, we highlight three relationship characteristics—favorability, history, and directness—and theorize that the reputation judgments of constituents with more unfavorable, longer, and more direct relationships with an organization are more stable, whereas the reputation judgments of constituents with more favorable, shorter, and more indirect relationships with the organization are less stable. We then develop the concept of reputational communities as a key source of indirect information about organizations. We highlight that the immediacy, size, and level of agreement within reputational communities affect how influential they are in changing individual constituents’ reputation judgments. Specifically, we propose that more immediate and larger reputational communities with a higher level of agreement are most likely to change individual constituents’ reputation judgments, whereas more distant and smaller reputational communities with a lower level of agreement are least likely to do so. Overall, we position constituents’ relationships with an organization and the communities that surround these relationships as central elements for understanding reputational stability and change.
Psychology Exceptionalism and the Multiple Discovery of the Replication Crisis

This article outlines what we call the “narrative of psychology exceptionalism” in commentaries on the replication crisis: many thoughtful commentaries link the current crisis to the specificity of psychology’s history, methods, and subject matter, but explorations of the similarities between psychology and other fields are comparatively thin. Historical analyses of the replication crisis in psychology further contribute to this exceptionalism by creating a genealogy of events and personalities that shares little in common with other fields. We aim to rebalance this narrative by examining the emergence and evolution of replication discussions in psychology alongside their emergence and evolution in biomedicine. Through a mixed-methods analysis of commentaries on replication in psychology and the biomedical sciences, we find that these conversations have, from the early years of the crisis, shared a common core that centers on concerns about the effectiveness of traditional peer review, the need for greater transparency in methods and data, and the perverse incentive structure of academia. Drawing on Robert Merton’s framework for analyzing multiple discovery in science, we argue that the nearly simultaneous emergence of this narrative across fields suggests that there are shared historical, cultural, or institutional factors driving disillusionment with established scientific practices.
