Monitoring profiles in multistage processes using the multivariate multiple regression model
Authors: Park Changsoon , Lee Jaeheon 
Published: June 2022

AbstractMost recent production processes comprise multiple stages, where the final quality of products is determined by the upstream effects of output quality at each stage. Moreover, the quality of each stage is characterized by a functional relationship, referred to as a profile, between input variables and output quality variables. Therefore, the effective profile monitoring of the multiple stages is crucial in maintaining and improving the final output quality. A multistage process is separated into a series of single‐stage processes, and each single‐stage process is treated as a profile structure. In each stage, we implement the multivariate multiple linear regression (MMLR) model using the orthogonal design coding. The coefficient estimators of the MMLR are obtained as a matrix, whose column vectors indicate the coefficient vectors for given output quality variables and row vectors indicate the coefficients of output quality variables for given regression coefficients. Since the use of orthogonal design coding makes the regression coefficient estimator vectors for the intercept and the input variables mutually independent, it is possible to monitor the process using Hotelling's T2 charts separately. We explain the process of estimating and monitoring the regression coefficients from Phase I samples, and evaluate the performance of the proposed procedure in Phase II.
A linear time method for the detection of collective and point anomalies
Authors: Fisch Alexander T. M. , Eckley Idris A. , Fearnhead Paul 
Published: June 2022

AbstractThe challenge of efficiently identifying anomalies in data sequences is an important statistical problem that now arises in many applications. Although there has been substantial work aimed at making statistical analyses robust to outliers, or point anomalies, there has been much less work on detecting anomalous segments, or collective anomalies, particularly in those settings where point anomalies might also occur. In this article, we introduce collective and point anomalies (CAPA), a computationally efficient approach that is suitable when collective anomalies are characterized by either a change in mean, variance, or both, and distinguishes them from point anomalies. Empirical results show that CAPA has close to linear computational cost as well as being more accurate at detecting and locating collective anomalies than other approaches. We demonstrate the utility of CAPA through its ability to detect exoplanets from light curve data from the Kepler telescope and its capacity to detect machine faults from temperature data.
Daily expression of workaholism and family outcomes: The buffering and magnifying effects of economic resources

Published: June 2022

AbstractWorkaholism is increasingly recognized as a potential threat to occupational health. Although most research has conceptualized workaholism as a trait, some research suggests that it may also fluctuate from day to day. Moreover, the effects of the dynamic properties of workaholism on work and family outcomes may be contingent on one's economic situation. Therefore, the aim of the present study was to test the interactive effect of workday workaholism and economic resources on nightly work‐family conflict and family engagement. Using experience sampling methodology, we demonstrated that workaholism fluctuates from one day to the next and has detrimental short‐term effects on work‐family conflict. Additionally, our findings indicated that the interaction between workday workaholism and perceived income adequacy predicted both nighty work‐family conflict and family engagement. While the association between workday workaholism and work‐family conflict was stronger for those who experienced low income adequacy, the relationship between workaholism and family engagement was stronger for those who exhibited high income adequacy. Similarly, job security buffered the effect of workaholism on work‐family conflict. We discuss the theoretical and practice implications of this study as well as recommend future research directions.
Switchable and Strain‐Releasable Mg‐Ion Diffusion Nanohighway Enables High‐Capacity and Long‐Life Pyrovanadate Cathode

Published: June 2022

AbstractRechargeable magnesium batteries (RMBs) suffer from low capacity and poor cyclability of cathode materials, which is due to the sluggish Mg2+ diffusion kinetics and large lattice strain. Here, a layer‐interweaving mechanism in lamellar cathode to simultaneously facilitate Mg2+ diffusion and release Mg2+‐insertion strain is reported. In the Cu3V2O7(OH)2·2H2O (CVOH) cathode, Mg2+ diffusion highways are generated by the vertical interweaving of CVOH layers and V6O13 layers that nucleate in CVOH during discharging, which are switchable by Mg2+ insertion/extraction. These highways enhance the Mg2+ diffusion coefficient by three orders of magnitude and release 50% Mg2+‐insertion strain. This enables CVOH to exhibit a high capacity of 262 mAh g−1 at high current density of 250 mA g−1 in aqua, and extremely low capacity loss of 0.0004% per cycle in the activated carbon//CVOH cell. This work inspires designing the magnesiation phase transformation of electrodes to resolve both kinetic and strain issues for high‐performance RMBs.

Published: June 2022

AbstractIt remains a challenge to develop cost‐effective, high‐performance oxygen electrocatalysts for rechargeable metal–air batteries. Herein, zinc‐mediated zeolitic imidazolate frameworks are exploited as the template and nitrogen and carbon sources, onto which is deposited a Fe3O4 layer by plasma‐enhanced atomic layer deposition. Controlled pyrolysis at 1000 °C leads to the formation of high density of Fe3O4‐x few‐atom clusters with abundant oxygen vacancies deposited on an N‐doped graphitic carbon framework. The resulting nanocomposite (Fe3O4‐x/NC‐1000) exhibits a markedly enhanced electrocatalytic performance toward oxygen reduction reaction in alkaline media, with a remarkable half‐wave potential of +0.930 V versus reversible hydrogen electrode, long‐term stability, and strong tolerance against methanol poisoning, in comparison to samples prepared at other temperatures and even commercial Pt/C. Notably, with Fe3O4‐x/NC‐1000 as the cathode catalyst, a zinc–air battery delivers a high power density of 158 mW cm−2 and excellent durability at 5 mA cm−2 with stable 2000 charge–discharge cycles over 600 h. This is ascribed to the ready accessibility of the Fe3O4‐x catalytic active sites, and enhanced electrical conductivity, oxygen adsorption, and electron‐transfer kinetics by surface oxygen vacancies. Further contributions may arise from the highly conductive and stable N‐doped graphitic carbon frameworks.

Published: June 2022

AbstractBackgroundThere has been increasing provision of veterinary telemedicine consultations, particularly during the COVID‐19 pandemic; however, little evidence currently exists examining these remote consultations. The aim of this cross‐sectional study was to explore veterinary and cat owner experiences of telemedicine consultations during the pandemic.MethodsTwo questionnaires, one aimed at veterinary professionals and one at cat owners, were launched in September 2020. Questions explored the type of consultation conducted remotely, the perceived advantages and disadvantages of telemedicine, and the role of telemedicine in the future of veterinary practice.ResultsResponses were received from 242 veterinary professionals and 98 owners with experience of telemedicine. Monitoring and advice consultations were felt to be most suited to telemedicine. Reduced stress for owners/cats was seen as an advantage of telemedicine, while lack of clinical examination and risk of misdiagnosis were viewed as disadvantages. Most respondents (85.7% [n = 84/98] of owners; 67.4% [n = 163/242] of veterinary professionals) felt practices should continue to offer telemedicine consultations.ConclusionWith increasing pet ownership and practice workload, telemedicine may play a crucial role in the future of veterinary practice. Future work should focus on a strategic approach to feline telemedicine, integrating it alongside face‐to‐face visits and developing technologies to maximise its advantages.
The RGG motif proteins: Interactions, functions, and regulations
Authors: Chowdhury Mashiat N. , Jin Hong 
Published: June 2022

AbstractProteins with motifs rich in arginines and glycines were discovered decades ago and are functionally involved in a staggering range of essential processes in the cell. Versatile, specific, yet adaptable molecular interactions enabled by the unique combination of arginine and glycine, combined with multiplicity of molecular recognition conferred by repeated di‐, tri‐, and multiple peptide motifs, allow RGG motif proteins to interact with a broad range of proteins and nucleic acids. Furthermore, posttranslational modifications at the arginines in the motif extend the RGG protein's capacity for a fine‐tuned regulation. In this review, we focus on the biochemical properties of the RGG motif, its molecular interactions with RNAs and proteins, and roles of the posttranslational modification in modulating their interactions. We discuss current knowledge of the RGG motif proteins involved in mRNA transport and translation, highlight our merging understanding of their molecular functions in translational regulation and summarize areas of research in the future critical in understanding this important family of proteins.This article is categorized under:

Migration and the Nation
Authors: Triandafyllidou Anna 
Published: June 2022

AbstractDuring the last decade, we have witnessed two opposed social and political trends. On the one hand, there has been a comeback of nationalism. Examples abound from Trump’s “make America great again”, to Modi’s Hindu nationalism, to Bolsonaro’s Brazilian populist nationalism, to Orbán’s Hungary, and Le Pen’s or Salvini’s ‘patriotic’ overtones, only to name a few. These parties promote aggressive, nativist, and populist nationalism discourses which see the relations between nations and nation-states as a zero-sum game. They privilege erecting borders, both territorial and symbolic, against minorities, migrants or refugees, other nation-states and supra-national political formations like, in Europe, the European Union.
Transnationalism
Authors: Pries Ludger 
Published: June 2022

AbstractTransnationalism as a research program has emerged in the social sciences since the 1990s. It refers to studies concentrating on social relations and groups that extend across the borders of nation-states. Referring to the degree of density and durability of such social interactions, often transnational social relations, social fields, and social spaces, are distinguished. Transnational families and transnational organisations are of particular relevance. The global, and even increasing significance of economic, social, cultural, and political remittances reflect the societal reality of transnational life.
Cities of Migration
Authors: Pisarevskaya Asya , Scholten Peter 
Published: June 2022

AbstractCities are often the main hubs or portals for migration. They are the places where people leave from, and where they first arrive at, after their migration journey, either to settle or to move on. They are also the places where diversities and mobilities become the most manifest. Built into the cross-roads of ancient trade routes, cities have been the centres for encounters between many cultures since ancient times. In the past, cities attracted internal migrants from rural areas, while nowadays, many cities have been shaped by a long history of international migration. For instance, the development of cities such as New York or London cannot be understood without taking into account their long migration histories. Indeed, in developing countries like Russia, China, South Africa, and Nigeria, urbanisation is still ongoing; both internal rural-urban or periphery-centre migrants, together with international migrants, are attracted to capital city urban centres, and this magnetism in turn shapes diversity landscapes.
Gender and Migration
Authors: Kofman Eleonore , Raghuram Parvati 
Published: June 2022

AbstractIn the past few decades,genderhas become one of the most significant optics through which to view and analyse migration. Migration has moved up the political agenda and women and men have become differentially entangled within these discussions. In this chapter we review some of the ways in which gender appears in migration debates, the different arguments around gender and on the forms of migration through which these have been routed, and some questions for future research agendas. This chapter is therefore necessarily selective and unable to provide a comprehensive review of the rich literature on the topic.
Migration and Development
Authors: Ullah Akm Ahsan 
Published: June 2022

AbstractAcademically speaking, migration has not been discussed intensely within a development framework until recently (Ullah & Haque, 2020). The seasonal flights of Siberian birds have long been associated with migration. When it comes to human mobility, however, migration has traditionally been viewed as a means of escaping unwanted situations in search of a more welcoming environment. Migration has existed since the dawn of time, but it has never occupied a substantial place in academe or policy spheres until today. Some countries formalised migration only recently. China, for example, did not allow people to move internally and internationally until 1979 (Xiang, 2016; Skeldon, 1996; Ullah & Hossain, 2014).
Migration Histories
Authors: Schrover Marlou 
Published: June 2022

AbstractIt is impossible to cover the history of global migrations in one chapter. The literature on global migration has increased rapidly since the 1980s. This increase is more-or-less in line with the increase in publications on migration control and migration management. The number of publications about global migrationhistoryis much less. This chapter will and cannot not cover the global migrations in the past 2000 years, but rather it will look critically at data collections, present biases inmigration history, and will give a helicopter view of major migrations.
Digital Migration Infrastructures
Authors: Preiss Carlotta 
Published: June 2022

AbstractDigitalisation has fundamentally shaped the way people migrate. On the one hand, refugees rely on digital services to navigate, access information, contact smugglers and stay in touch with their families and other refugees. On the other hand, marriage migration, labour migration and student mobility are facilitated by online matchmaking, recruitment and advertisements. This chapter conceptualises the ensemble of digital technologies facilitating migration as Digital Migration Infrastructures. It also provides an overview over the literature and highlights the growing impact of digital technologies on migration processes whilst identifying the remaining research gaps.
Labour Migration
Authors: Oso Laura , Kaczmarczyk Paweł , Salamońska Justyna 
Published: June 2022

AbstractThis chapter will focus on labour migration, that is the movement of persons with the aim of employment or income-bringing activities (e.g., entrepreneurship), developing the topic which was also touched upon in Chap. 3 on conceptual understanding of migration drivers. Research on labour migration has developed across various disciplines (e.g., sociology, anthropology, and geography), but most prominently in economics. It has resulted in a range of theoretical frameworks, starting with neoclassical economic theories and advancing through the New Economics of Labour Migration (NELM), dual labour market theory, and social network theory, to more recent transnational approaches or theories dedicated to particular forms of labour migration. These diverse approaches offer insights into labour migration on macro-, meso- and micro-levels. Although a dichotomy based on skills (high-skilled vs. low-skilled workers) can be seen as controversial or misleading as a division between workers representing these two types of skills is often vague or difficult to determine, the distinction does reflect recent debates on labour migration. Thus, a high−/low-skills dichotomy serves as a guide to the structure of this chapter.

AbstractCiguatoxins are marine compounds that share a ladder-shaped polyether structure produced by dinoflagellates of the genus Gambierdiscus and Fukuyoa, and include maitotoxins (MTX1 and MTX3), ciguatoxins (CTX3C) and analogues (gambierone), components of one of the most frequent human foodborne illness diseases known as ciguatera fish poisoning. This disease was previously found primarily in tropical and subtropical areas but nowadays, the dinoflagellates producers of ciguatoxins had spread to European coasts. One decade ago, the European Food Safety Authority has raised the need to complete the toxicological available data for the ciguatoxin group of compounds. Thus, in this work, the in vivo effects of ciguatoxin-related compounds have been investigated using internationally adopted guidelines for the testing of chemicals. Intraperitoneal acute toxicity was tested for maitotoxin 1 at doses between 200 and 3200 ng/kg and the acute oral toxicity of Pacific Ciguatoxin CTX3C at 330 and 1050 ng/kg and maitotoxin 1 at 800 ng/kg were also evaluated showing not effects on mice survival after a 96 h observation period. Therefore, for the following experiments the oral subchronic doses were between 172 and 1760 ng/kg for gambierone, 10 and 102 ng/kg for Pacific Ciguatoxin CTX3C, 550 and 1760 ng/kg for maitotoxin 3 and 800, 2560 and 5000 ng/kg for maitotoxin 1. The results presented here raise the need to reevaluate the in vivo activity of these agents. Although the intraperitoneal lethal dose of maitotoxin 1 is assumed to be 50 ng/kg, without chemical purity identifications and description of the bioassay procedures, in this work, an intraperitoneal lethal dose of 1107 ng/kg was obtained. Therefore, the data presented here highlight the need to use a common procedure and certified reference material to clearly establish the levels of these environmental contaminants in food.
