Authors: Ben Romdhane Youssra , Kammoun Souhaila , Werghi Imen 
Published: May 2022

PurposeThe purpose of this paper is to study the impact of economic factors on foreign direct investment (FDI) inflows into Asian region before and after the COVID-19 pandemic.Design/methodology/approachThe study used the generalized method of moments (GMM) technique to examine the impact of economic growth, domestic investment and trade openness on FDI in the Asian region, in two periods from 1996 to 2018 and from 2019 to 2020.FindingsIn the pre-COVID-19 period, the estimated result shows that the economic growth, domestic investment, imports and exports positively impact FDI. In the post-COVID-19 period, the FDI is influenced by the strength of the economic characteristics of the region. The main findings indicate that economic growth has a positive and significant effect on FDI inflows into Asia. The findings also show that the economic resilience to attract FDI in Asia is significantly affected by economic growth and positively affected by trade openness and government responses during the pandemic.Originality/valueThe study suggests the Asian governments increasing the domestic investment and improving the quality of trade openness.
An improved fatigue life prediction model based on loading sequence
Authors: Xue Qiwen , Du Xiuyun 
Published: May 2022

PurposeIn view of the difficulty in determining the key parameters d in the Corten-Dolan model, based on the introduction of small loads, damage degrees and stress states to the Corten-Dolan model and the existing improved model, the sequential effects of the adjacent two-stage load were further considered.Design/methodology/approachTwo improved Corten-Dolan models were established on the basis of modifying the parameter d by two different methods, namely, increasing stress ratio coefficient as well as considering the effects of loading sequence and damage degree as independent influencing factors respectively. According to the test data of the welded joints of common materials (standard 45 steel), alloy materials (standard 16Mn steel) and Q235B steel, the validity and feasibility of the above two improved models for fatigue life prediction were verified.FindingsResults show that, compared with the traditional Miner model and the existing Corten-Dolan improved model, the two improved models have higher prediction accuracy in the fatigue life prediction of welding materials whether under two-stage load or multi-stage load.Originality/valueBecause the mathematical expressions of the models are relatively simple and need no multi-layer iterative calculation, it is convenient to predict the fatigue life of welded structure in practical engineering.

Authors: Dahmani Massicilia , Seghir Abdelghani , Issaadi Nabil , Amiri Ouali 
Published: May 2022

Purpose
This study aims to propose a numerical modeling procedure for response analysis of elastic body floating in water and submitted to regular waves. An equivalent simplified mechanical single-degree-of-freedom system allowing to reproduce the heave movements is first developed, then the obtained lumped characteristics are used for elastic analysis of the floating body in heave motion.

Design/methodology/approach
First, a two-dimensional numerical model of a rigid floating body in a wave tank is implemented under DualSPHysics, an open source computational fluid dynamics (CFD) code based on smoothed particle hydrodynamics method. Then, the obtained results are exploited to derive an equivalent mechanical mass-spring-damper model. Finally, estimated equivalent characteristics are used in a structural finite element modeling of the considered body assuming elastic behavior.

Findings
Obtained results concerning the floating body displacements are represented and validated using existing experimental data in the literature. Wave forces acting on the body are also evaluated. It was found that for regular waves, it is possible to replace the complex CFD refined model by an equivalent simplified mechanical system which makes easy the use of structural finite element analysis.

Originality/value
The originality of this work lies in the proposed procedure to evaluate the mechanical properties of the equivalent elastic system. This allows to couple two different software tools and to take advantages of their features.

Published: May 2022

AbstractObjectiveA new virtual ED service was introduced into a hospital network in the northern suburbs of Melbourne in response to changing needs during the COVID‐19 pandemic. The ‘virtual ED’ utilises a telehealth model as a means of assessment for appropriately selected patients to facilitate either complete care or navigation into streamlined pathways for ongoing care, in some cases bypassing the ED entirely where appropriate. The proposed study aims to evaluate the implementation of the model and identify future improvement opportunities, assess the impact on traditional health service delivery processes and patient experience, and determine the acceptability of the ‘virtual ED’ model of care.MethodsThe present study will consist of a pre‐post‐ implementation evaluation using the RE‐AIM framework. Routine health service data will be collected for 6 months post‐implementation of the virtual ED model and compared to 24 months prior to implementation. Prospective data will be collected using routinely collected and survey data. Interviews and focus groups will be conducted to understand consumer and clinician perspectives on barriers and enablers to implementation and adoption of the virtual ED.ResultsDescriptive statistics will be used to describe the study population and key outcomes, including changes in ED presentations and length of stay. Thematic analysis will be conducted on transcribed interviews and focus group data. This will be triangulated with data collected from patient feedback surveys.ConclusionThis project will support the delivery of care to ED patients by evaluating the ‘virtual ED’ model of care.
Intermittent methionine restriction reduces IGF‐1 levels and produces similar healthspan benefits to continuous methionine restriction
Authors: Plummer Jason D. , Johnson Jay E. 
Published: May 2022

AbstractA sustained state of methionine restriction (MR) dramatically extends the healthspan of several model organisms. For example, continuously methionine‐restricted rodents have less age‐related pathology and are up to 45% longer‐lived than controls. Promisingly, MR is feasible for humans, and studies have suggested that methionine‐restricted individuals may receive similar benefits to rodents. However, long‐term adherence to a methionine‐restricted diet is likely to be challenging for many individuals. Prompted by this, and the fact that intermittent variants of other healthspan‐extending interventions (i.e., intermittent fasting and the cyclic ketogenic diet) are just as effective, if not more, than their continuous counterparts, we hypothesized that an intermittent form of MR might produce similar healthspan benefits to continuous MR. Accordingly, we developed two increasingly stringent forms of intermittent MR (IMR) and assessed whether mice maintained on these diets demonstrate the beneficial metabolic changes typically observed for continuous MR. To the best of our knowledge, we show for the first time that IMR produces similar beneficial metabolic effects to continuous MR, including improved glucose homeostasis and protection against diet‐induced obesity and hepatosteatosis. In addition, like continuous MR, IMR confers beneficial changes in the plasma levels of the hormones IGF‐1, FGF‐21, leptin, and adiponectin. Together, our findings demonstrate that the more practicable intermittent form of MR produces similar healthspan benefits to continuous MR, and thus may represent a more appealing alternative to the classical intervention.
Shorting costs and profitability of long–short strategies
Authors: Kim Dongcheol , Lee Byeung‐Joo 
Published: May 2022

AbstractWe examine how the profitability of long–short arbitrage strategies based on anomalies is affected after adjustment for two shorting costs: implicit cost due to unavailability of stocks in the short‐leg to sell short and loan fees actually paid to stock lenders. The combined shorting cost amounts to almost 40 percent of long–short gross returns over the sample period from January 2006 to December 2017. After adjustment for these shorting costs, long–short arbitrage profits are thus reduced by almost 40 percent. Even after adjustment for risk, the proportion of shorting costs is also substantial. If other trade‐related transaction costs are considered, long–short arbitrage profits would be reduced further. Our results provide explicit evidence that casts doubt on the profitability of long‐short arbitrage strategies based on anomalies.

AbstractContarinia brassicola Sinclair (Diptera: Cecidomyiidae) is a recently described species found infesting canola (Brassica napus L. and Brassica rapa L., Brassicaceae) in western Canada. There is concern that C. brassicola could have economic impacts on canola production. To learn about its biology, distribution, natural enemies, and potential impact, we conducted a prairie‐wide survey in western Canada and field studies using emergence cages and plant dissections between 2017 and 2019. Results of a transect‐based survey conducted in Alberta, Saskatchewan, and Manitoba indicated that C. brassicola is widely distributed in western Canada. Two species of parasitic wasp were reared from C. brassicola larvae collected during the survey. We found that C. brassicola can have multiple generations per year, with the first peak of adult emergence occurring in early July with the onset of the susceptible crop stage. Adult midge and larvae may be found from June until early autumn. Midge larvae appear capable of extended diapause over multiple years. During this study, we found that C. brassicola damage was restricted to developing flowers. In the vast majority of fields surveyed, C. brassicola occurred in low population densities and was unlikely to impact yield in those fields.
The Golden Billion: Russia, COVID, Murderous Global Elites
Authors: Cherkaev Xenia 
Published: May 2022

SUMMARYThis essay tells the story of the hot, brooding summer that preceded Russia’s “special military operation” attack on Ukraine: an attack that could not legally be called a war and that many people in Russia supported even while they neither trusted the media nor cared to talk about politics. Rallying support for this undeclared war, Russian state rhetoric drew on images of WWII fascism, NATO expansion, and morally rotten transnational elites: themes resonant with long‐standing feelings of hurt national pride and personal abandonment in the face of spiraling social stratification. To many of its supporters, “the war seemed a relief after many years of stagnation,” wrote the Moscow‐based journalist Shura Burtin (2022). “Like a fire in prison: at least there’ll be some commotion.” This essay describes a high point of this pregnant stagnation. Written in August 2021, it draws on over a decade of ethnographic fieldwork in North‐Western Russia to examine the idea that a “Golden Billion” of the world’s most powerful people governs to exterminate the rest of us—at a moment when this idea seemed eminently reasonable.
Dependency and aged care in Spain: Tensions and contradictions in a society in transition

Published: May 2022

AbstractDependency and care assistance during old age has become an increasing focus of debate and change in society. Consequently, people must cope with diverse and even contradictory values and ideas about the issue. This study aimed to understand the social representations of dependency based on the dialogical approach of the Social Representations theory. Total 26 semi‐structured interviews were conducted in the Basque Country (north of Spain) with relatives, care workers, and older adult care recipients. The thematic analysis results show that social representations are articulated around seven themes, reflecting people's tensions and contradictions at cultural, organizational, and relational levels. In addition, the polyphasic and dynamic nature of social representations is discussed, addressing current public debates about the meaning of dependency in a changing sociocultural context.

AbstractA 40‐year‐old woman underwent right lobe thyroidectomy for thyroid nodules that increased in size from 17 mm to 33.5 mm within 1 year. Identification of arteria lusoria using computed tomography suggested the presence of a right nonrecurrent laryngeal nerve (RNRLN). Endoscopic thyroidectomy was performed under general anesthesia. The right vagal nerve was first identified between the common carotid artery and jugular vein. A positive response was confirmed via intraoperative neuromonitoring (IONM), implying that the RNRLN did not branch from the central side of the stimulated point of the vagal nerve. The RNRLN was confirmed using IONM around the middle to lower pole of the right thyroid gland. The right thyroid lobe was successfully removed, with meticulous preservation of the RNRLN. The motion of the vocal cord, examined by an ear‐nose‐throat doctor postoperatively, was intact. We demonstrated the efficacy of IONM in patients with RNRLN who underwent endoscopic thyroidectomy.
Comparison of the effects of perineural or intravenous dexamethasone on thoracic paravertebral block in Ivor‐Lewis esophagectomy: A double‐blind randomized trial

Published: May 2022

AbstractEfforts to prolong thoracic paravertebral block (TPVB) analgesia include local anesthetic adjuvants, such as dexamethasone (Dex). Previous studies showed that both perineural (PN) and intravenous (i.v.) routes could prolong analgesia. As PN Dex is an off‐label use, anesthesiologists should be fully informed of the clinical differences, if any, on block duration. This study was designed to evaluate the two administration routes of Dex for duration of analgesia in TPVB. Ninety‐five patients scheduled for Ivor‐Lewis esophagectomy were randomized to receive TPVB (0.5% ropivacaine 15 ml), PN or i.v. Dex 8 mg. The primary end point was the duration of analgesia. The secondary end points included pain scores, analgesic consumption, adverse effects rate, and incidence of chronic pain at 3 months postoperatively. The PN‐Dex group showed better analgesic effects than the i.v.‐Dex group (p < 0.05). Similarly, the visual analogue scale scores in patients at 2, 4, 8, and 12 h postoperatively were lower in the PN‐Dex group than the i.v.‐Dex group (p < 0.05). The analgesic consumption in both the PN‐Dex and i.v.‐Dex groups was significantly lower than that in the control group (p < 0.05). Regarding the incidence of chronic pain, regardless of route, Dex decreased the incidence of chronic postsurgical pain and neuropathic pain at 3 months after surgery (p < 0.05), but there were no clinical differences between the i.v.‐Dex and PN‐Dex groups. Perineural dexamethasone improved the magnitude and duration of analgesia compared to that of the i.v.‐Dex group in TPVB in Ivor‐Lewis esophagectomy. However, there were no clinically significant differences between the two groups in the incidence of chronic pain.
Causal inference on the engagement effects of athletic participation from within‐student variation
Authors: DiSalvo Richard W. , Che Jing 
Published: May 2022

AbstractWe study how athletic participation relates to two measures of engagement, school attendance and disciplinary suspension, among students in an urban school district. Following one strand of the literature, we study within‐student variation, comparing the same student when playing sports versus not. To this literature, we contribute a microeconomic model to better interpret estimates obtained using such variation, and we propose and employ novel instrumental variables based on lagged season‐specific sports choices and the sports‐specific participation trajectories of other students. Our most rigorous models suggest positive effects of athletics on student attendance, but no significant effects on disciplinary suspension.

AbstractGlobalization has led to the introduction of thousands of alien species worldwide. With growing impacts by invasive species, understanding the invasion process remains critical for predicting adverse effects and informing efficient management. Theoretically, invasion dynamics have been assumed to follow an “invasion curve” (S‐shaped curve of available area invaded over time), but this dynamic has lacked empirical testing using large‐scale data and neglects to consider invader abundances. We propose an “impact curve” describing the impacts generated by invasive species over time based on cumulative abundances. To test this curve's large‐scale applicability, we used the data‐rich New Zealand mud snailPotamopyrgus antipodarum, one of the most damaging freshwater invaders that has invaded almost all of Europe. Using long‐term (1979–2020) abundance and environmental data collected across 306 European sites, we observed thatP. antipodarumabundance generally increased through time, with slower population growth at higher latitudes and with lower runoff depth. Fifty‐nine percent of these populations followed the impact curve, characterized by first occurrence, exponential growth, then long‐term saturation. This behaviour is consistent with boom‐bust dynamics, as saturation occurs due to a rapid decline in abundance over time. Across sites, we estimated that impact peaked approximately two decades after first detection, but the rate of progression along the invasion process was influenced by local abiotic conditions. The S‐shaped impact curve may be common among many invasive species that undergo complex invasion dynamics. This provides a potentially unifying approach to advance understanding of large‐scale invasion dynamics and could inform timely management actions to mitigate impacts on ecosystems and economies.
Characterisation of a New Delta‐Zero Natural Mg Solution Alfa‐Mg for Isotope Ratio Measurement and Mg Isotopic Values in Fourteen Matrix Reference Materials
Authors: Liu Jinke , Han Guilin 
Published: May 2022

The Mg isotope system helps constrain a variety of geochemical processes in the hydrosphere, lithosphere and biosphere. DSM3 is commonly used as delta‐zero material for relative Mg isotopic measurements. In this study, we have characterised the Mg isotopic composition of a new pure Mg solution (Alfa‐Mg). This solution could potentially be used as a secondary delta‐zero reference material, or as an alternative primary reference material when DSM3 is depleted. The Alfa‐Mg solution has been checked for homogeneity and stability and is available free of charge upon request. The certified δ26/24Mg value relative to DSM3 of the Alfa‐Mg solution is −1.40‰, with an expanded (k = 2) uncertainty of 0.05‰. We also characterised a range of existing Earth‐surface reference materials including soils, riverine sediments and plants. The δ26/24Mg values (relative to DSM‐3) of plant materials range between −1.06 ± 0.03‰ (2s, n = 12) and −0.75 ± 0.03‰ (2s, n = 12). The δ26/24Mg values of soil materials vary from −0.72 ± 0.11‰ (2s, n = 12) to 0.17 ± 0.05‰ (2s, n = 12). The δ26/24Mg values of riverine sediment materials range between −0.66 ± 0.01‰ (2s, n = 12) and −0.17 ± 0.03‰ (2s, n = 12). These data could serve as a reference for inter‐laboratory calibration and quality control, as well as for potential applications in geological and biological fields.

Published: May 2022

AbstractIntroductionPerioperative dosing recommendations vary across Nordic haemophilia treatment centres (HTCs) for extended half‐life (EHL) factor concentrates in haemophilia A/B (HA/HB) patients.AimTo summarise Nordic real‐world surgical experiences with EHL recombinant factor VIII/IX Fc (rFVIIIFc/rFIXFc) fusion proteins using retrospective data from clinical records at four HTCs in Finland, Sweden and Norway.MethodsFactor dosing and surgical outcomes were recorded from HA/HB patients who underwent surgery and were treated with rFVIIIFc/rFIXFc. Perioperative factor dosing regimens were clinician‐determined based on local practises.ResultsTwenty five surgeries were performed on 20 patients, all covered by bolus injections except one minor HA surgery; eight minor surgeries were in paediatric patients. Median preoperative rFVIIIFc dose for major HA surgeries (n = 8) was 48 IU/kg (range: 35–57), with total consumption up to Day 14 of 427 IU/kg (196–568). For the two major HB surgeries (in one patient), preoperative rFIXFc doses were 50 IU/kg and 20 IU/kg; total consumption up to Day 14 was 130 IU/kg and 40 IU/kg. Median preoperative rFVIIIFc/rFIXFc bolus doses for minor HA (n = 10) and HB (n = 4) surgeries were 50 IU/kg (24–79) and 47 IU/kg (40–71), with total consumption up to Day 5 of 138 IU/kg (49–404) and 100 IU/kg (43–125), respectively. Intraoperative and postoperative haemostatic responses were rated as at least good/excellent for 24/25 surgeries, with bleeding episodes reported in only three surgeries.ConclusionNordic real‐world experiences suggest that EHL products can be used safely and effectively for peri‐operative haemostasis. Further research is required to develop local dosing guidelines for optimised treatment schedules.
Bone marrow and peripheral blood involvement of relapsed diffuse large B‐cell lymphoma after prior cold agglutinin disease
Authors: Chang Soon Hee 
Published: May 2022

AbstractThe author report an interesting case of relapsed diffuse large B‐cell lymphoma (DLBCL) with bone marrow (BM) and peripheral blood (PB) involvement after prior cold agglutinin disease (CAD). A minority of patients with DLBCL present with CAD, and BM or PB involvement with CAD are quite rare. Differential diagnosis of patients with CAD should include DLBCL, considering the possibility of BM or even PB involvement.
