Authors: Springer Mellanie V. , Skolarus Lesli E. , Feng Chunyang , Burke James F. 
Published: March 2022

Background
The aim of this study was to discussions about post‐stroke outcomes related to post‐stroke function and post‐acute care discharge setting.inform patient‐provider.

Methods and Results
We conducted a retrospective cohort study of Medicare beneficiaries with acute ischemic stroke or intracerebral hemorrhage in 2013. Our primary outcome was mortality within at least 1‐year post discharge. We performed multivariate logistic regression to estimate 90‐day odds ratios (ORs) and Cox proportional hazards regression to estimate post 90‐day hazard ratios on mortality, adjusting for demographics, procedures, comorbidities, discharge setting (inpatient rehabilitation facility, skilled nursing facility, or home health care agency), post‐stroke function (measured by the Functional/Pseudo‐Functional Independence Measure) and setting‐function interactions. There were 167 000 patients with a mean follow‐up of 441 days. Mortality within 90 days was associated with post‐stroke function (OR, 0.23; 95% CI, 0.19–0.27 comparing highest to lowest quintile of post‐stroke function) and discharge setting (OR, 4.05; 95% CI, 3.78–4.33 for skilled nursing facility versus inpatient rehabilitation facility). Among the highest functioning patients, those discharged to inpatient rehabilitation facility had a 1‐year mortality of 9% and those discharged with home health had 11% mortality at 1 year. The lowest functioning survivors of stroke discharged to a skilled nursing facility had 64% mortality at 1 year and those discharged to an inpatient rehabilitation facility had 29.6% mortality at 1 year.

Conclusions
Nearly two thirds of the lowest functioning survivors of stroke discharged to a skilled nursing facility die within a year. This finding should inform discussions between providers and patients/caregivers in aligning goals of care with the care survivors of stroke receive.
Insurgent Armies: Military Obedience and State Formation after Rebel Victory
Authors: Martin Philip A. 
Published: March 2022

Abstract
Why do some winning rebel groups build obedient and effective state militaries after civil war, while others suffer military defections? When winning rebels face intense security threats during civil wars, rebel field commanders are more likely to remain obedient during war-to-peace transitions. Intense security threats incentivize militants to create more inclusive leadership structures, reducing field commanders’ incentives to defect in the postwar period. Intense security threats also reduce commanders’ capacity for postwar resistance by forcing insurgents to remain mobile and adopt shorter time horizons in rebel-governed territory, reducing the likelihood that field commanders will develop local ties and independent support bases. The plausibility of the argument is examined using a new list of winning rebel groups since 1946. Two case studies—Zimbabwe and Côte d'Ivoire—probe the causal mechanisms of the theory. The study contributes to debates about the consequences of military victory in civil war, the postwar trajectories of armed groups, and the conditions necessary for civil-military cohesion in fragile states.
Parameter Identification Problem in the Hodgkin-Huxley Model
Authors: Valle Jemy A. Mandujano , Madureira Alexandre L. 
Published: March 2022

Abstract
The Hodgkin-Huxley (H-H) landmark model is described by a system of four nonlinear differential equations that describes how action potentials in neurons are initiated and propagated. However, obtaining some of the parameters of the model requires a tedious combination of experiments and data tuning. In this letter, we propose the use of a minimal error iteration method to estimate some of the parameters in the H-H model, given the measurements of membrane potential. We provide numerical results showing that the approach approximates well some of the model's parameters, using the measured voltage as data, even in the presence of noise.
Notes for a Biography: A Portrait of Isaiah Sonne (1887–1960)
Authors: Mampieri Martina 
Published: March 2022

Abstract
Isaiah Sonne (1887–1960) was a distinguished scholar, paleographer, bibliographer, librarian, book dealer, and collector whose activities spanned Habsburg Galicia, Fascist Italy, Mandatory Palestine, and the United States during the first six decades of the 20th century. Although he was a prolific author and appreciated by many individuals especially because of his paleographic skills and profound knowledge of Jewish manuscripts and early printed books, his life and scholarship have only received modest attention since his death. The portrait offered in this brief article represents the first fruits of a book project that aims to produce the very first cultural biography of this scholar.
Oceanic Rossby Waves Induced Two Types of Ocean–Atmosphere Response and Opposite Indian Ocean Dipole Phases
Authors: Zhang Yuhong , Du Yan 
Published: March 2022

AbstractThis study analyzed the downwelling Rossby waves in the south Indian Ocean (IO)-induced spring asymmetric mode and the relationship with the Indian Ocean dipole (IOD) event based on observations and reanalysis datasets. The westward downwelling Rossby waves favor significant sea surface temperature (SST) warming in the Seychelles thermocline dome that triggers atmosphere response and the asymmetric mode in spring. The zonal sea level pressure gradient causes anomalous easterly winds in the central and eastern equatorial IO, cooling the SST off Sumatra–Java. Meanwhile, the remainder of the downwelling Rossby waves reach the west coast, transform to northward coastal-trapped waves, and then reflect as eastward downwelling Kelvin waves along the equator. The downwelling Kelvin waves reach the Sumatra–Java coast during late spring to early summer, favoring SST warming in the southeastern tropical Indian Ocean. Thus, there are two types of ocean–atmosphere response almost at the same time along the equator. The final SST status depends on which process is stronger and, as a consequence, triggers a negative or a positive phase of the IOD event in the fall season. The results show four positive and three negative IOD events related to the above processes from 1960 to 2019. The strong downwelling Rossby waves are easier to induce an intense asymmetric mode and negative IOD event, usually associated with preceding strong El Niño in the Pacific. In contrast, the weak downwelling Rossby waves tend to induce a weak asymmetric mode and positive IOD event, usually associated with preceding weak El Niño or anomalous anticyclonic atmospheric circulation in the southeastern IO.

Abstract
To improve the wind speed forecasts at turbine locations and at hub height, this study develops the WRFDA system to assimilate the wind speed observations measured on the nacelle of turbines (hereafter referred as turbine wind speed observations) with both 3DVAR and 4DVAR algorithms. Results exhibit that the developed data assimilation (DA) system helps in greatly improving the analysis and the forecast of wind turbine speed. Among three experiments with no cycling DA, with 2-h cycling DA, and with 4-h cycling DA, the last experiment generates the best analysis, improving the averaged forecasts (from T + 9 to T + 24) of wind speed over all wind farms by 32.5% in the bias and 6.3% in the RMSE. After processing the turbine wind speed observations into superobs, even bigger improvements are revealed when validating against either the original turbine wind speed observations or the superobs. Taken the results validated against the superobs as an example, the bias and RMSE of the forecasts (from T + 9 to T + 24) averaged over all wind farms are reduced by 38.8% and 12.0%, respectively. Compared to the best-performed 3DVAR experiment (4-h cycling and superobs), the experiment following the same DA strategy but using 4DVAR algorithm exhibits further improvements, especially for the averaged bias in the forecasts of all wind farms, and the changing amount in the forecasts of the enhanced wind farms. Compared to the control experiment, the 4DVAR experiment reduces the bias and RMSE in the forecasts (from T + 9 to T + 24) by 54.6% (0.66 m s−1) and 12.7% (0.34 m s−1).
The appropriating subject: Cultural appreciation, property and entitlement
Authors: Cattien Jana , Stopford Richard John 
Published: March 2022

What is cultural ‘appropriation’? What is cultural ‘appreciation’? Whatever the complex answer to this question, cultural appropriation is commonly defined as ‘the taking of something produced by members of one culture by members of another’ (Young 2005: 136), whilst appreciation is typically understood as mere ‘exploration’: ‘Appreciation explores whatever is there’. (Gracyk 2007: 112). These provisional definitions suggest that there is an in-principle distinction between the two concepts that presupposes the following: what is appreciated is already available; what is appropriated was, prior to its being taken, not already there or available. Moreover, perhaps appreciation, when contrasted to appropriation, is unproblematic precisely due to this basic difference. In this paper, we argue that the exclusive disjunction – appropriation or appreciation – rests on a false distinction between the two. We also show that this distinction presupposes a false normative principle that to the extent that x is appreciation rather than appropriation, then x is not – relevant to this issue – a wrong. Against these presuppositions, we defend the view that appropriation is already built into appreciation. This does not mean that we cannot ask questions of appreciation, but that questions of appreciation do not preclude the problematics of appropriation.

Published: March 2022

Background: Labral augmentation has emerged as an essential procedure to address a deficient or irreparable labrum while preserving native labral tissue and restoring the hip suction seal mechanism. Purpose: To evaluate midterm outcomes of arthroscopic hip labral augmentation for labral insufficiency after previous hip arthroscopy. Study Design: Case series; Level of evidence, 4. Methods: Patients were identified from a prospectively collected database who underwent arthroscopic hip labral augmentation between January 2011 and January 2017 with a minimum 3-year follow-up. Pre- and postoperative patient-reported outcome scores were compared and included the 12-Item Short Form Health Survey physical and mental component summaries, Western Ontario and McMaster Universities Osteoarthritis Index, modified Harris Hip Score (mHHS), and Hip Outcome Score (HOS) (Activities of Daily Living [ADL] and Sport). Postoperative Tegner Activity Scale and patient satisfaction (1-10) scores were also evaluated. The minimal clinically important difference (MCID) and Patient Acceptable Symptom State (PASS) between the preoperative and minimum 3-year follow-up scores were calculated. Results: A total of 88 patients (39 men, 49 women) underwent revision hip arthroscopy with labral augmentation. The average age was 32.8 ± 11 years. Of these, 77 patients (88%) were available for the minimum 3-year follow-up. The survivorship (absence of conversion to total hip arthroplasty) at 3 years and 5 years was 93% at both time points, with a mean survival time of 8.5 years (95% CI, 8.0-8.9). Eleven patients (14%) required revision arthroscopic surgery for continued pain. Revisions occurred at a mean of 2.6 ± 1.4 years after augmentation. The mean follow-up was 5.2 ± 1.2 years (range, 3-9 years). For patients not requiring subsequent surgery (n = 61), all patient-reported outcome measures significantly improved, which included a 20-point increase in HOS-ADL (MCID, 82%; PASS, 72%) and mHHS (MCID, 78%; PASS, 70%). The median postoperative Tegner score was 4 (range, 1-10). The median postoperative patient satisfaction score was 9 out of 10 (range, 1-10). Conclusion: Arthroscopic hip labral augmentation is a successful treatment option for patients with labral insufficiency after previous hip arthroscopy, demonstrating improved patient-reported outcomes and survivorship of 93% at 3 years and 5 years. This technique provides a valuable labral preservation option when addressing hip labral pathology when viable native labral tissue remains.

Published: March 2022

Objectives Using data from a large random sample of U.S. older adults ( N = 7982), the effect of loneliness and social isolation on all-cause mortality was examined considering their separate and combined effects. Methods The UCLA-3 Loneliness Scale and the Social Network Index (SNI) were used to define loneliness and social isolation. Cox proportional hazards regression models were performed. Results Among study participants, there were 548 deaths. In separate, adjusted models, loneliness (severe and moderate) and social isolation (limited and moderate social network) were both associated with all-cause mortality. When modeled together, social isolation (limited and moderate social network) along with severe loneliness remained significantly associated with mortality. Discussion Results demonstrate that both loneliness and social isolation contribute to greater risk of mortality within our population of older adults. As the COVID-19 pandemic continues, loneliness and social isolation should be targeted safely in efforts to reduce mortality risk among older adults.

Published: March 2022

Continuous drive friction welding (CDFW) is an economical and productive method for joining similar metals. In this study, 45 # steel was joined via CDFW, and the material heat distribution, flow behaviour, flash formation and fracture mode were investigated via experiments and simulations. The bar was divided into three zones in the direction of radius (R), the R zone near the axis, the edge zone at the edge of the R and the 0.5 R zone between the R zone and edge zone. The maximum flow velocity and temperature of the joint first appeared in the 0.5 R zone, and as the friction continued, the maximum temperature moved to the edge zone, followed by flash. When the friction time was 9 s, the maximum tensile strength was 674 MPa, the fracture mode was the coexistence of ductile and brittle and the fracture location had an obvious boundary. Ductile fracture occurred in the R zone, and the flash took a lot of heat, brittle fracture occurred in the 0.5 R and edge zones. The maximum microhardness of the joint is 295 HV in the weld zone, and the microhardness decreased in the partially deformed zone. When the friction time was appropriate, the heat distribution was uniform and sufficient, and the grains exhibited a significant degree of dynamic recrystallisation refinement.

Published: March 2022

Objective: To explore the mechanism by which electroacupuncture (EA) upregulates triggering receptor expressed on myeloid cells 2 (TREM2) protein in the hippocampus of Alzheimer’s disease (AD) model animals from the perspective of TREM2 DNA methylation. Methods: In total, 24 eight-month-old senescence-accelerated mouse prone 8 (SAMP8) mice were divided into an (untreated) AD group (n = 8), donepezil group (receiving donepezil treatment, n = 8) or EA group (receiving an EA intervention, n = 8). A healthy control group comprising 8-month-old senescence-accelerated mouse resistant 1 (SAMR1) mice (n = 8) was also included. Western blotting, bisulfite sequencing, and oxidative bisulfite sequencing were applied to test the relative expression of TREM2 protein and the methylation levels of the TREM2 gene. Results: EA significantly upregulated the relative expression of TREM2 protein (p < 0.01), downregulated the 5-methylcytosine level (p < 0.01) and upregulated the 5-hydroxymethylcytosine level (p < 0.05) in the hippocampus. Conclusion: Downregulation of 5-methylcytosine levels and upregulation of 5-hydroxymethylcytosine levels in the TREM2 gene might be the mechanism by which EA promotes the expression of TREM2 protein.

Published: March 2022

Objective: The objective of this study is to evaluate the efficacy and safety of electroacupuncture (EA) treatment for post-stroke depression (PSD). Methods: This study was a single-center, single-blinded, parallel-arm randomized controlled trial. In total, 65 patients with PSD were randomly allocated into EA and sham EA groups. Treatment was administered at GV20, Sishencong, SP6, LR3 and BL18 in both groups. The EA group received EA treatment, while the sham EA group received sham EA treatment using the Park device. Treatment was given three times a week for 4 weeks. The primary outcome was the Hamilton Rating Scale for Depression (HRSD). Secondary outcomes included the Zung Self-Rating Depression Scale (SDS), National Institutes of Health Stroke Scale (NIHSS), Barthel Daily Living Index (BI) and depression scale of traditional Chinese medicine (TCM). Primary and secondary outcomes were assessed at baseline, week 2 after treatment, week 4 after treatment and week 8 of follow-up. Safety assessment was conducted at each visit for 4 weeks of treatment. Results: Significant differences in HRSD, SDS, NIHSS, BI and TCM scale scores were found in the EA group before and after acupuncture treatment (all p < 0.001). Compared with the sham EA group, HRSD scores improved significantly in the EA group at the end of week 2 (F = 31.33, p < 0.001), week 4 (F = 35.58, p < 0.001) and week 8 after treatment onset (F = 25.03, p < 0.001). Similarly, significant improvements were observed in SDS, NIHSS and BI scores. Two participants in the EA group suffered a local hematoma, while no adverse events were reported in the sham EA group. Conclusion: EA appears to be an efficacious and safe treatment for PSD. According to our results, EA may alleviate depressive symptoms, and improve neurological function and capabilities with respect to activities of daily living (ADLs).

Dividend policy from the perspective of social system theory
Authors: Wechta Przemysław 
Published: March 2022

AbstractThe aim of the article is to analyse the functions that dividends perform in contractual relationships between public companies’ executives and shareholders. The author analyses the income function of dividend, but also considers its sociological aspects. Talcott Parsons' social system theory is the main point of reference, especially, the concept of contract institution. The article justifies the thesis on the relevance of dividends in shaping the equilibrium of power, information policy and the composition of shareholders in a joint-stock company. Dividend policy has a great regulatory potential, which is important in the face of various crises occurring in contemporary capitalism.
Uneven domestic tourism demand in times of pandemic
Authors: Falk Martin , Hagsten Eva , Lin Xiang 
Published: March 2022

This study investigates the short-run impact of the COVID-19 pandemic on the number of domestic overnight stays at the regional level in the summer season 2020. Official data for 65 regions in four countries are used for the analysis (Austria, the Czech Republic, Germany and Switzerland). Dynamic panel data models are employed to estimate a tourism demand equation (real GDP and price fluctuations) augmented by average temperatures. Estimation results reveal that domestic overnight stays evolve unevenly in the first summer after the outbreak of the COVID-19 pandemic. The short-run effects show that the number of domestic overnight stays in densely populated regions decreases by 27% in July as well as in August 2020, in comparison with the same months in previous years, ceteris paribus. To the contrary, there is a surge of 27 and 10%, respectively, for sparsely populated areas in the same months. JEL: Z3, R11 and R12.
A culturally grounded autism parent training program with Black parents

Published: March 2022

Parent training (i.e. group-based supports and psychoeducation aimed at parent as primary agent of change) in Autism Spectrum Disorders (autism) is well-documented as an Evidence-Based Intervention designed to increase advocacy, knowledge, and empowerment. While research on Parent Training acknowledges the cultural limitations, the field lacks culturally grounded models. Furthermore, barriers in diagnosis, service acquisition, and inclusion of under-represented populations including Black families have been established; however, research programs have traditionally failed to include these families. This study aims to provide a first toward addressing the lack of inclusion. We describe the practice-based implementation of a culturally concordant Parent Training program (Spectrum of Care) developed by a community organization (the Color of Autism) as well as feedback from parents after the implementation process. The findings indicate that culturally grounded strategies could promote engagement and empowerment of Black families. There, however, is still a need for research that attends to parental mistrust and examines culturally grounded strategies more closely. Lay abstract Parent training programs have been well-studied in Autism Spectrum Disorders and shown to increase a parent’s feeling of empowerment, advocacy skills, and treatment enrollment for their child. The majority of parent training interventions have been developed without considering the unique needs of under-represented communities, such as the Black community. Black children with autism are not only misdiagnosed or not diagnosed at all, but are not accessing services equally compared to their White peers. There is an urgent need for culturally adapted interventions in order to decrease the disparity gap. The Color of Autism Foundation developed and ran a parent training program for Black parents of children with autism. The program was grounded in two key features: (1) creating a circle of support for parents to connect and heal from ongoing and historical racial trauma and (2) using parents of Black children with autism as the main facilitators. We believe this increased parent’s ability to engage in the educational aspects of the training. Overall, parents reported high levels of satisfaction with the training were highly engaged (attended an average of five of six sessions) and reported high levels of empowerment. Parents also reported continued mistrust in the medical and research community and a need for more Black providers. Further work should examine the relationship of the parent and provider in autism treatment and study the impact of circles of healing for Black families.
