Repetitive Emissions of Rising‐Tone Chorus Waves in the Inner Magnetosphere

Chorus waves in the inner magnetospheres of the Earth and other magnetized planets typically occur in the form of discrete and repetitive quasi‐monochromatic emissions with a frequency chirping, which was discovered more than 50 years ago. However, until now there is still no satisfactory explanations for repetitive emissions of chorus waves. In this Letter, chorus emissions excited by energetic electrons with a temperature anisotropy are studied by a one‐dimensional PIC‐ δf simulation in a dipole magnetic field, and it is demonstrated that a continuous injection of energetic electrons caused by an azimuthal drift is essential for the repetitive emissions of chorus waves. Consistent with satellite observations, both discrete and continuous spectra can be reproduced. An intense injection of energetic electrons will lead to a decrease of the time separation between the chorus elements, and the chorus emissions evolve from a discrete to a continuous spectrum when the injection is sufficiently strong.
(Non)Environmental Alternative Action Organizations under the Impacts of the Global Financial Crisis: A Comparative European Perspective

Hard economic times have been considered obstacles for environmental activism by many environmental scholars, yet works, mostly based on case studies, on alternative action organizations (AAOs) during times of increasing livelihood vulnerability show considerable environmental activism. We explain this inconsistency by arguing that AAOs mobilizing at times of crisis opt for direct action, using strategies of citizens’ solidarity initiatives centering on meeting basic needs and sustainability goals and thereby carry on the environmental claim-making in a new way. To this end, we compare environmental AAOs (EAAOs) with non-environmental ones using a cross-national dataset of 4157 hubs-retrieved AAOs active during the economic crisis (2007–2016), in France, Greece, Germany, Italy, Poland, Spain, Sweden, Switzerland, and the UK. Given that EAAOs constitute more than one-third of all AAOs, it is clear that environmental protection or sustainable development are not neglected even at times of economic hardships. Instead, the crisis provides an opportunity to broaden the scope of action for existing organizations that can adopt sustainability activities focusing on alternative practices and lifestyles, improving societal resilience. We further show that EAAOs tend to be informal and, to an extent, more concentrated on contention and protests than non-environmental organizations.
Computational analysis of reinforced concrete structures subjected to fire using a multilayered finite element formulation

Fire is a critical risk in reinforced concrete (RC) structures and appropriate structural resistance against it has to be ensured. In this contribution, an approach using corotational layered beam finite elements is employed in which the cross-section temperature is derived from a low-cost closed form model, as opposed to the more commonly used fully computational thermal analysis. The effect of geometrical and material nonlinearities (constitutive behavior fitted to experimental data for concrete and steel), material degradation as a function of temperature rise, and the contributions of thermal, transient, and creep strains are incorporated in the structural analysis. The computational results are favorably compared to experimental data from the literature for an RC beam and for a larger RC frame. Taking benefit of the layered beam formulation offering local insight into the cross-sectional and material behavior, the relationship between the structural degradation and data extracted from the cross-sectional behavior is successfully established. Noteworthy originalities of the contribution are the use of ultimate strain and its evolution as a function of temperature for both materials and the explanation of the observed structural response in fire conditions from cross-sectional data.
School readiness of five-year-old children from socio-economically disadvantaged areas: evidence from the Preparing for Life evaluation

Being school-ready when transitioning to the primary school system has been associated with favourable outcomes during schooling and adult life. While children living in socio-economically disadvantaged areas may be at a higher risk of being less school-ready, research in the area has highlighted that not all children experience such a delay. This study examined a range of factors that may account for differences in outcomes across five school readiness domains (physical health and well-being, social competence, emotional maturity, language and cognitive development, and communications skills and general knowledge) within a sample of children living in socio-economically disadvantaged areas. Drawing on data from a sample of five-year-old children involved in the Preparing for Life (PFL) evaluation in Ireland, this study explored the role of child and early environmental factors in facilitating or hindering children’s development across these school readiness domains. Statistical analysis identified child’s sex, parental involvement and learning materials at home, parent–child interactions, mother’s attempt to breastfeed, and mother–child attachment as significant predictors of school readiness after accounting for other factors. Findings contribute to the Irish and international literature on the role of early demographical and environmental factors in shaping school readiness, especially for children from socio-economically disadvantaged areas.
Travelers’ Adoption Behavior towards Electric Vehicles in Lahore, Pakistan: An Extension of Norm Activation Model (NAM) Theory

This study aims to identify the travelers’ adoption behavior towards electric vehicles (EVs) using the theoretical background of the Norm Activation Model (NAM) theory. A questionnaire was designed and conducted in Lahore, Pakistan. A total of 402 usable samples were obtained. The collected data were analyzed using factor analysis and Structural Equation Modeling methods. The factor analysis confirmed the hypothesis of the statements designed according to the NAM theory, that is, awareness of consequences (AC), ascription of responsibility (AR), and personal norm (PN). Other factor analyses resulted in the following reliable factors: social and economic values (SEV), personal preferences (PP), willingness to buy (Buy), and willingness to use (Use) of an EV. The results of SEM revealed that the AC, AR, and SEV are significant predictors of PN, whereas the PN and PP are also positive predictors of travelers’ willingness to buy and use. The young travelers (≤30 years), motorcycle users, employees, and trip distance (>10 km) have significant and positive correlations with the PN. The car ownership status of travelers has a positive correlation with the ownership and usage of EVs. Suitable behavioral intervention techniques were derived to promote the ownership and usage of EVs in the context of developing regions.
The growth impact of trade openness: A comparative analysis of the USA and China

Given the continuum of views regarding the impact of trade openness on the growth of economies in our globalised world, this paper investigates the comparative case of the USA and China, two of the world’s largest economies and power houses, for the period 1985–2020. We find contradicting growth effects of trade in the US and China, with trade having a mixed or negative effect on the former but a consistently positive effect on the latter, both in the short and long run. We provide some commentary in light of the recent global debates on trade and propose policy recommendations in the context of these countries.
Determining Stock Return movements of Banking Sector during Global Financial Crisis: An Examination on Emerging Markets of Bangladesh

The objective of the study is to explore various micro and macro variables that affect stock returns of the Dhaka Stock Exchange surrounding the global financial crisis. We collect a sample of 30 listed banks covering the period of 9 years (2009 – 2017) for our study. The results indicate that debt to asset ratio (D/A), market capitalization (MKT CAP), interest rate, and foreign exchange rate (ForEx Rate) have positive and significant relationships with stock returns. On the other hand, inflation and leverage have negative and significant influence on stock returns among the eight micro variables and four macroeconomic variables that were used in our analyses.
COVID-19 vaccine confidence and tourism at the early stage of a voluntary mass vaccination campaign: a PMT segmentation analysis

ABSTRACT Restarting the mass tourism industry relies on the success of the COVID-19 vaccination campaign which requires individuals’ voluntary participation to reduce health risks to hosts and visitors. This study identifies segments of Italian residents based on vaccine confidence at the early stage of a voluntary mass vaccination programme. Using a survey held with 3893 Italian residents, two COVID-19 vaccine confidence clusters were identified. These clusters were compared and revealed significant differences in response and self-efficacy, vaccine adoption, travel behaviour and involvement in the tourism industry.

Novel Consistency Check For Fast Recursive Reconstruction Of Non-Regularly Sampled Video Data

Quarter sampling is a novel sensor design that allows for an acquisition of higher resolution images without increasing the number of pixels. When being used for video data, one out of four pixels is measured in each frame. Effectively, this leads to a non-regular spatio-temporal sub-sampling. Compared to purely spatial or temporal sub-sampling, this allows for an increased reconstruction quality, as aliasing artifacts can be reduced. For the fast reconstruction of such sensor data with a fixed mask, recursive variant of frequency selective reconstruction (FSR) was proposed. Here, pixels measured in previous frames are projected into the current frame to support its reconstruction. In doing so, the motion between the frames is computed using template matching. Since some of the motion vectors may be erroneous, it is important to perform a proper consistency checking. In this paper, we propose faster consistency checking methods as well as a novel recursive FSR that uses the projected pixels different than in literature and can handle dynamic masks. Altogether, we are able to significantly increase the reconstruction quality by + 1.01 dB compared to the state-of-the-art recursive reconstruction method using a fixed mask. Compared to a single frame reconstruction, an average gain of about + 1.52 dB is achieved for dynamic masks. At the same time, the computational complexity of the consistency checks is reduced by a factor of 13 compared to the literature algorithm.
Rebirth of the cool: the modern renaissance of low titer group O whole blood for treating massively bleeding civilian patients

: The use of whole blood for the resuscitation of trauma patients is not a new concept, but rather it traces its history to the first world war. Whole blood is currently experiencing a renaissance given the modern appreciation for the need for balanced resuscitation and the survival benefits of the early intervention of blood products. According to the AABB Standards, when used in an uncrossmatched manner, the whole blood must be group O and contain low titer anti-A and -B; this product is known as low titer group O whole blood (LTOWB). The serological safety of using LTOWB in the civilian adult and pediatric settings have been demonstrated, and the Standards require each institution to determine the maximum number of units that each patient can receive, the titer threshold, and to set a policy about which patients can receive LTOWB. Unresolved questions surrounding the use of LTOWB include for how long the platelets are active during cold storage, whether leukoreduction affects platelet function, a titer threshold that optimizes patient safety and LTOWB inventory management, and whether LTOWB provides a mortality benefit compared to using conventional components. Another question that needs to be answered is whether RhD-positive red blood cell (RBC) containing products should be administered to females of childbearing potential whose RhD-type is unknown during the pre-hospital phase of the resuscitation. 15 of other so that blood collectors that are considering implementing an LTOWB program can estimate the impact of the program on their group O RBC collections using their local data.
Utilization of Carrot Pomace to Grow Mealworm Larvae (Tenebrio molitor)

Edible insects are a sustainable food source to help feed the growing population. Mealworms (Tenebrio molitor) can survive on a variety of food wastes and alter their composition based on the feed source. Commercial carrot production produces an abundance of carotenoid-rich carrot pomace, which may be beneficial for mealworm larvae growth. This study uses an I-optimal response surface design to assess the effect of dehydrated carrot pomace concentrations (made up with wheat bran as the control) in the substrate and wet carrot pomace as the moisture source (potato and carrot as control moisture sources) in a mealworm-larvae-growing system. Using this design, statistical models were fit to determine the relationship between the substrate and moisture and dependent variables, which include mealworm larvae mortality, days to maturity, weight, protein content, fat content, moisture content, ash content, and total carotenoid content. An optimum diet was proposed, in which the best diet for improving commercial mealworm growth was found to contain 36% dehydrated carrot pomace in the substrate, with wet carrot pomace as the moisture source. This research provides an application for a commercial waste stream and provides insight to help improve the growth of a sustainable protein source.
Privacy-Aware Fuzzy Skyline Parking Recommendation Using Edge Traffic Facilities

Drivers have always been confronted with real-time parking difficulties when driving on urban roads, especially in crowded downtown or beauty spots. On the other hand, privacy leakage risks on users’ private parking preferences and the sensitive data of parking lots have triggered increasing worries. Some literatures endeavor to improve parking service qualities through multi-consideration parking decision optimization on edge sides or cloud computing based on outsourced data storage. And some other literatures propose a number of privacy-preserving methods, such as cryptography and authentication, but these privacy strategies are at the expense of other qualities of parking services, especially the real-time performance. In this paper, we propose a fuzzy skyline parking recommendation scheme for real-time parking recommendation based on roadside traffic facilities. Linguistic parking information instead of raw parking-related data is used in fuzzy skyline fusion. We evaluated our solution with real-world data sets collected from parking facilities in Wulin downtown, Hangzhou city, China. The evaluation results show that our approaches achieve an average accuracy of parking recommendation over 91%, low communication cost, and quick response time with privacy protection.
Capsule Vehicle Dynamics Based on Levitation Coil Design Using Equivalent Model of a Sidewall Electrodynamic Suspension System

A levitation system based on sidewall electrodynamic suspension (EDS) is considered for a capsule vehicle, which is a next-generation high-speed transportation system currently being studied. This levitation system does not require controlling of the gap between the guideway and the vehicle on which the superconducting electromagnet is mounted. However, when the vehicle is operated in a levitated state, the ride comfort is worse than that of the levitation system based on electromagnetic suspension (EMS), making it necessary to develop methods that can ensure good riding comfort. In addition, because the EDS system is complex and nonlinear with a combination of electromagnetics and mechanical dynamics, it is complicated to analyze the dynamic characteristics of the capsule vehicle, and the corresponding numerical analysis is time-consuming. Therefore, to easily understand the running dynamics of a capsule vehicle in the sidewall EMS system, the magnetic suspension characteristics corresponding to the primary suspension are simply modeled by considering the levitation stiffness in the vertical direction and the guidance stiffness in the lateral direction, similar to that in the case of the mechanical suspension. In this study, mathematical models of the levitation and guidance stiffnesses with respect to the speed and position of a vehicle body running at high speeds in a levitated state in the sidewall EDS system were derived for three design proposals of the levitation coil. The dynamic behavior of the vehicle based on the three design proposals was investigated by simulating a capsule vehicle model with 15 degrees of freedom.
Supply chain redesign in the aquaculture supply chain: a longitudinal case study

Abstract Companies aiming to upgrade their supply chains to meet operational and sustainability objectives are often required to redesign their supply networks. However, there is scarce empirical evidence on how to redesign existing supply chains, especially global supply chains. This longitudinal case study examined the aquaculture supply chain redesign process with the aim of improving market, operational, and sustainability performance. Aquaculture, although characterized as the blue revolution, has received little attention in management studies. Action research collected evidence via informal interviews, participant observation, on-site visits, and secondary data selection. The redesign process included three phases: (i) physical distribution network mapping, risk-uncertainty analysis, and hierarchical goal setting, (ii) implementation of physical network re-design, and (iii) performance monitoring, control, and continuous improvement. The company achieved significant lead time reduction and fast response to the markets while, at the same time, reducing environmental pollution and meeting sustainable targets. The study uncovers that supply chain redesign should not be limited to physical network restructuring but also include facilities value extension and integrated information management. It shows how companies can mitigate different types of risks (supply, production, logistics, demand) via specific supply chain redesign interventions.
Remembering the coup, celebrating the revolution: securitization of memory and mnemonical disputes in Brazil

ABSTRACT Led by the Armed Forces, the 1964 coup inaugurated a dark time in Brazil, with suspension of political rights, censorship, and human rights violations in the context of the Cold War. Although the 2011 National Truth Commission was able to produce a report on the human rights violations, it seems many Brazilians prefer to forget the years of lead. While the military regime remains a scar in Brazil's history, the 2018 election of Jair Bolsonaro, a retired Army Captain who had previously called the military regime a glorious period, has produced a cabinet mostly occupied by retired military officers who do not feel they should be apologetic towards the coup. The aim of this article is to highlight the dynamics of an on-going mnemonic war over the very meaning of 1964 as a historical event of political rupture in Brazil, which points to the securitization of memory in Bolsonaro's regime.
Home in question: Uncovering meanings, desires and dilemmas of non-home

What is the opposite of home? Is it necessarily something ‘negative’? Similar questions, far from having a self-evident answer, make for a fruitful entry point for research into the social experience of home. Central to this article is a novel conceptualization of non-home, against the background of the pre-existing criticisms of the normative, romanticized and depoliticized understandings of home. This article draws from fieldwork on the everyday dwelling experience of migrants and asylum seekers to illustrate the volitional dimension of non-home. Not attaching a sense of home to a dwelling place or set of relationships is not merely a consequence of poor housing conditions. It may also involve an active choice – at least at some points of the life course, in certain household conditions. In this sense, non-home is more than a matter of absence, dispossession, reconfiguration or implosion of home. In questioning the normative view of home as inherently positive and desirable, this conceptualization highlights the reciprocal interaction between home and non-home as mutually interdependent constructs.
Tropical cyclone climatology change greatly exacerbates US joint rainfall-surge hazard

Tropical cyclones (TCs) are among the largest drivers of extreme rainfall and surge, but current and future TC joint hazard has not been well quantified. We utilize a physics-based approach to simulate TC rainfall and storm tides and quantify their joint hazard under historical conditions and a future (SSP5 8.5) climate projection. We find drastic increases in the frequency of exceeding joint historical 100-yr hazard levels by 2100, with a 10–36 fold increase along the southern US coast and 30–195 fold increase in the northeast. The joint hazard increase is induced by sea-level rise and TC climatology change; the relative contribution of TC climatology change is higher than that of sea-level rise for 96% of the coast due to large increases in rainfall. Increasing storm intensity and decreasing translation speed are the main TC change factors that cause higher rainfall and storm tides and up to 25% increase in their dependence.
Synthesis, characterization, and antimicrobial activity of novel N-acetyl,N’-chitosanacetohydrazide and its metal complexes

Abstract A new modified chitosan derivative (N-acetyl,N’-chitosanacetohydrazide, ACsAH) and its cobalt(II), nickel(II), manganese(II), and copper(II) complexes were successfully prepared. Their structures were proven using elemental analysis, FTIR, 1H-NMR and electronic spectroscopy, magnetic moment, and molar conductance. An octahedral stereochemistry for all the synthesized ACsAH–metal complexes was proposed. Their activity against the tested microbes can be arranged as follows: ACsAH–Mn(II) complex > ACsAH–Co(II) complex > ACsAH–Ni(II) complex > ACsAH–Cu(II) complex > ACsAH > chitosan. The ACsAH–Mn(II) complex exhibited a greater potency in inhibition of the growth of some of the tested microbes than that of the used standard drugs. Graphical Abstract
