Background:
Mortality following discharge in myocardial infarction survivors remains high. Therefore, we compared outcomes in myocardial infarction survivors participating and not participating in a novel, nationwide managed care program for myocardial infarction survivors in Poland.

Methods:
We used public databases. We included all patients hospitalized due to acute myocardial infarction in Poland between October 1, 2017 and December 31, 2018. We excluded from the analysis all patients aged <18 years as well as those who died during hospitalization or within 10 days following discharge from hospital. All patients were prospectively followed. The primary end point was defined as death from any cause.

Results:

The mean follow-up was 324.8±140.5 days (78 034.1 patient-years; 340.0±131.7 days in those who did not die during the observation). Participation in the managed care program was related to higher odds ratio of participating in cardiac rehabilitation (4.67 [95% CI, 4.44–4.88]), consultation with a cardiologist (7.32 [6.83–7.84]), implantable cardioverter-defibrillator (1.40 [1.22–1.61]), and cardiac resynchronization therapy with cardioverter-defibrillator implantation (1.57 [1.22–2.03]) but lower odds of emergency (0.88 [0.79–0.98]) and nonemergency percutaneous coronary intervention (0.88 [0.83–0.93]) and coronary artery bypass grafting (0.82 [0.71–0.94]) during the follow-up. One-year all-cause mortality was 4.4% among the program participants and 6.0% in matched nonparticipants. The end point consisting of all-cause death, myocardial infarction, or stroke occurred in 10.6% and 12.0% (
P
<0.01) of participants and nonparticipants respectively, whereas all-cause death or hospitalization for cardiovascular reasons in 42.2% and 47.9% (
P
<0.001) among participants and nonparticipants, respectively. The difference in outcomes between patients participating and not participating in the managed care program could be explained by improved access to cardiac rehabilitation, cardiac care, and cardiac procedures.

Conclusions:
Managed care following myocardial infarction may be related to improved prognosis as it may facilitate access to cardiac rehabilitation and may provide a higher standard of outpatient cardiac care.
New Characteristics and Hedonic Price Index Numbers
Authors: Crawford Ian , Neary J. Peter 
Published: August 2021

Abstract
Changes in product characteristics on the extensive margin (the addition of new features and the removal of old ones) are an important and hitherto neglected dimension of quality change. Standard techniques for adjusting price indices for new goods cannot handle such changes satisfactorily, and this leads to an economically and statistically significant bias in the measurement of prices and real output. We combine insights from the theories of exact index numbers and demand for characteristics to develop a new method for incorporating changes on the extensive characteristic margin. Applied to U.K. data on new car sales, our method leads to revisions in estimated inflation rates for this commodity group that are both plausible and quantitatively important.
On the Estimation of Cross-Firm Productivity Spillovers with an Application to FDI
Authors: Malikov Emir , Zhao Shunan 
Published: August 2021

AbstractWe develop a novel methodology for the proxy variable identification of firm productivity in the presence of productivity-modifying learning and spillovers, which facilitates a unified internally consistent analysis of the spillover effects among firms. Contrary to the popular two-step empirical approach, ours does not postulate contradictory assumptions about firm productivity across the estimation steps. Instead, we explicitly accommodate cross-sectional dependence in productivity induced by spillovers, which facilitates identification of both the productivity and spillover effects simultaneously. We apply our model to study cross-firm spillovers in China's electric machinery manufacturing, with a particular focus on productivity effects of inbound FDI.
Benign Effects of Automation: New Evidence from Patent Texts
Authors: Mann Katja , Püttmann Lukas 
Published: August 2021

Abstract
We provide a new measure of automation based on patents and study its employment effects. Classifying all U.S. patents granted between 1976 and 2014 as automation or nonautomation patents, we document a strong rise in the number and share of automation patents. We link patents to their industries of use and to commuting zones. To estimate the effect of automation, we use an instrumental variables strategy that relies on innovations developed independently from U.S. labor market trends. We find that automation technology has a positive effect on employment in local labor markets, driven by job growth in the service sector.
Discrimination, Narratives, and Family History: An Experiment with Jordanian Host and Syrian Refugee Children
Authors: Barron Kai , Harmgart Heike , Huck Steffen , Schneider Sebastian O. , Sutter Matthias 
Published: August 2021

Abstract
We measure the prevalence of discrimination between Jordanian host and Syrian refugee children attending school in Jordan. Using a simple sharing experiment, we find only a small degree of out-group discrimination. However, Jordanian children with Palestinian roots do not discriminate at all, suggesting that a family history of refugee status can generate solidarity with new refugees. We also find that parents’ narratives about the refugee crisis are correlated with their children's degree of out-group discrimination, particularly among Syrian refugee children, suggesting that discriminatory preferences are being transmitted through parental attitudes.
Crisis and the Trajectory of Science: Evidence from the 2014 Ebola Outbreak
Authors: Fry Caroline Viola 
Published: August 2021

Abstract
When crises such as disease outbreaks occur in low-income countries, the global response can influence the output of researchers in the most affected locations. This paper investigates the impact of the 2014 West African Ebola epidemic on publication outcomes of endemic country scientists. Driven by collaborations with high-income country scientists in Ebola publications, endemic country scientists with relevant experience increase their publication output. However, the productivity of scientists without relevant experience falls, driving a reduction in non-Ebola publications. Any benefits arising from increased visibility during the epidemic does not appear to spill over to non-Ebola or Africa-led research in the long run.
The Speed of Justice
Authors: Kondylis Florence , Stein Mattea 
Published: August 2021

Abstract
Can procedural reforms improve judicial efficiency? And do improvements in judicial efficiency benefit firms? We combine the staggered rollout of a reform that required judges in Senegal to complete pretrials within four months with high-frequency caseload data and firm tax filings. The reform improved judicial efficiency, with no effect on quality. Firm monthly revenues drop by 8–11% upon entering pretrial and decline by on average 3.2–5.0% for every hundred days a case spends in pretrial. Survey results show firms are willing to pay higher legal fees to achieve postreform speed, suggesting positive benefits of the reform on firms.
Do We or Don’t We? Muslim Women Wearing the Hijab in the South African Work Environment
Authors: Carrim Nasima MH , Paruk Zeenat 
Published: August 2021

Abstract
This article examines the experiences of Muslim women who wear hijab in corporate South Africa. Muslim women from diverse organisations wearing hijab were interviewed. The study produced mixed results. While women who don the hijab were discriminated against in some organisations, in the majority of organisations religious pluralism is embraced. The results further indicate that although South Africa is a secular country, there are various pieces of legislation that protect employees from religious discrimination in the workplace. Employees who don the hijab at lower levels experienced more discrimination compared to those at higher levels. The study further revealed that donning the hijab for Muslim women is viewed from a holistic perspective which includes behaving appropriately and not attending social functions where their religious convictions are jeopardized. The results indicate that wearing the hijab does not impede their career advancement although it does have a negative impact when they attend job interviews in organisations other than their own.
Questioning Growth: Christianity, Development, and the Perils of Wealth in Southern Ethiopia
Authors: Sommerschuh Julian 
Published: August 2021

Abstract
Research on the economic effects of African Christianity has mainly focused on Pentecostalism. The dominant opinion of this literature is that Pentecostalism stimulates economic activity and supports economic development. This article looks beyond Pentecostalism by discussing the case of an Evangelical church in southern Ethiopia. Covering a period of two decades, I trace a shift in the relation between Evangelicalism and local aspirations for economic development. Initially seen as a means to achieve religious ends, the pursuit of development has recently been problematized as a source of social and spiritual ills. The church now discourages excessive participation in the commercial economy, and dedicated Evangelicals relinquish economic opportunities that they fear could lead them into sin. This shows that while Christianity can stimulate processes of economic development it can also constrain these, motivating people to renounce the quest for wealth in favour of other values.
The Vetting Impasse: The ‘Churches Law’ and Kenya’s Religious Regulation Debate
Authors: Gez Yonatan N. 
Published: August 2021

Abstract
Over the last decade Kenya has been seeing a lively debate over the regulation of its ever-expanding religious market and demands for a new ‘Churches Law’. Tales of hypocritical abuse of power and of emerging cults coalesced with security concerns regarding religious extremism, leading to the proposal to tighten regulatory control over the religious market, which expanded rapidly since the 1990s. Despite widespread recognition of the problem, new legislative steps have failed so far, notably even leading to a controversial 2014 moratorium on the registration of new religious denominations. This article analyzes this legislative impasse and offers an explanation in terms of the ambivalent yet symbiotic relations between religion and state in Kenya.
The Three-Cornered Hat Method for Estimating Error Variances of Three or More Atmospheric Data Sets – Part II: Evaluating Radio Occultation and Radiosonde Observations, Global Model Forecasts, and Reanalyses
Authors: Rieckh Therese , Sjoberg Jeremiah P. , Anthes Richard A. 
Published: August 2021

AbstractWe apply the three-cornered hat (3CH) method to estimate refractivity, bending angle, and specific humidity error variances for a number of data sets widely used in research and/or operations: radiosondes, radio occultation (COSMIC, COSMIC-2), NCEP global forecasts, and nine reanalyses. We use a large number and combinations of data sets to obtain insights into the impact of the error correlations among different data sets that affect 3CH estimates. Error correlations may be caused by actual correlations of errors, representativeness differences, or imperfect co-location of the data sets. We show that the 3CH method discriminates among the data sets and how error statistics of observations compare to state-of-the-art reanalyses and forecasts, as well as reanalyses that do not assimilate satellite data. We explore results for October and November 2006 and 2019 over different latitudinal regions and show error growth of the NCEP forecasts with time. Because of the importance of tropospheric water vapor to weather and climate, we compare error estimates of refractivity for dry and moist atmospheric conditions.
Influence of the Saharan Air Layer on Hurricane Nadine (2012). Part I: Observations from the Hurricane and Severe Storm Sentinel (HS3) Investigation and Modeling Results

Published: August 2021

AbstractThis study uses a model with aerosol–cloud–radiation coupling to examine the impact of Saharan dust and other aerosols on Hurricane Nadine (2012). To study aerosol direct (radiation) and indirect (cloud microphysics) effects from individual, as well as all aerosol species, eight different NU-WRF Model simulations were conducted. In several simulations, aerosols led to storm strengthening, followed by weakening relative to the control simulation. This variability of the aerosol impact may be related to whether aerosols are ingested into clouds within the outer rainbands or the eyewall. Upper-tropospheric aerosol concentrations indicate vertical transport of all aerosol types in the outer bands but only vertical transport of sea salt in the inner core. The results suggest that aerosols, particularly sea salt, may have contributed to a stronger initial intensification but that aerosol ingestion into the outer bands at later times may have weakened the storm in the longer term. In most aerosol experiments, aerosols led to a reduction in cloud and precipitation hydrometeors, the exception being the dust-only case that produced periods of enhanced hydrometeor growth. The Saharan air layer (SAL) also impacted Nadine by causing a region of strong easterlies impinging on the eastern side of the storm. At the leading edge of these easterlies, cool and dry air near the top of the SAL was being ingested into the outer-band convection. This midlevel low-equivalent-potential-temperature air gradually lowered toward the surface and eventually contributed to significant cold-pool activity in the eastern rainband and in the northeast quadrant of the storm. Such enhanced downdraft activity could have led to weakening of the storm, but it is not presently possible to quantify this impact.
Tracking Greenfield FDI During the COVID-19 Pandemic: Analysis by Sectors

Published: August 2021

We study the trends and fluctuations in greenfield foreign direct investment (GFDI) during the first wave of the COVID-19 pandemic crisis on a global scale. We analyse the data of a data set of GFDI provided by fDi Markets ( Financial Times) to understand the contraction of GFDI during the first three quarters of the year 2020, taking into account the sector of the investment and the host and home country. We analyse both the long-run trends and the quarter-over-quarter changes in GFDI to capture its fluctuations before and during the first wave of the COVID-19 crisis and the 2008 global financial crisis. Our findings cast light on which countries’ and industries’ GFDIs were most affected by the pandemic crisis and draw a comparison to the global financial crisis. To our surprise, many services industries have shown unexpected resilience of GFDI due to the flexibility for remote work. On the contrary, GFDI in the manufacturing industries, as well as the extractives and the utility industries, has shown a dramatic decline during the pandemic. These contractions raise questions of stability and resilience of the global supply chains these industries are a part of. JEL Codes: F21

Published: August 2021

Background Open globe injury (OGI) is a serious condition that can lead to visual impairment and lifelong sequelae, brain activity of some brain regions would change in patients with OGI. Purpose To evaluate changes in brain activity associated with unilateral OGI by resting-state functional magnetic resonance imaging (rs-fMRI) and analysis of percentage amplitude of fluctuation (PerAF). Material and Methods A total of 22 patients with OGI (12 men, 10 women) and 22 healthy controls (HCs) matched for sex, age, and body weight were enrolled. All patients underwent rs-fMRI scans. Brain activity in the relevant brain regions was assessed with the PerAF method. The ability of PerAF to distinguish patients with OGI from HCs was assessed by receiver operating characteristic (ROC) curve analysis. We also examined the relationship between Hospital Anxiety and Depression Scale (HADS) scores and PerAF signals by Pearson’s correlation analysis. Results PerAF values in amygdala_R and Frontal_Inf_Orb_L/Frontal_Inf_Oper_L were increased whereas that in Cerebellum Anterior Lobe/Cerebelum_8_L was decreased in patients with OGI compared to HCs. The areas under the ROC curve showed that these brain regions could distinguish between patients with OGI and HCs. The PerAF value of amygdala_R was positively correlated with HADS scores. Conclusion Changes in PerAF in the amygdala_R, Frontal_inferior_Orb_L/Frontal_Inf_Oper_L, and Cerebellum Anterior Lobe/Cerebelum_8_L in patients with OGI may be related to an increased risk of developing psychiatric disorders such as anxiety and depression. PerAF can be used to investigate the neural basis of complications associated with OGI and monitor disease progression.

Authors: Wang Nengmin , Tang Guwen , Jiang Bin , He Zhengwen , He Qidong 
Published: August 2021

Being a greener enterprise is the final goal of obtaining sustainable supply chain management, achieving environmental management (EM) and ensuring environmental performance. To provide scholars with knowledge of research trends of green enterprises, we carried out this research project, took 1142 articles as research objects and three methods to review the whole picture of green enterprises research. We found that this field is mainly concentrated in three areas. While small and medium-sized enterprises’ (SMEs) greening, EM and pollution emissions have been the enduring topics, green innovation has received the most attention from researchers. Furthermore, we found that scholars pay a great amount of attention to China-related research and Italian scholars have played a leading role in the future green enterprise research.JEL classification: Q57
Numerical prediction of noise generated from airfoil in stall using LES and acoustic analogy
Authors: Aihara Aya , Goude Anders , Bernhoff Hans 
Published: August 2021

This article presents the aerodynamic noise prediction of a NACA 0012 airfoil in stall region using Large Eddy Simulation and the acoustic analogy. While most numerical studies focus on noise for an airfoil at a low angle of attack, prediction of stalled noise has been made less sufficiently. In this study, the noise of a stalled airfoil is calculated using the spanwise correction where the total noise is estimated from the sound source of the simulated span section based on the coherence of turbulent flow structure. It is studied for the airfoil at the chord-based Reynolds number of 4.8 × 105 and the Mach number of 0.2 with the angle of attack of 15.6° where the airfoil is expected to be under stall condition. An incompressible flow is resolved to simulate the sound source region, and Curle’s acoustic analogy is used to solve the sound propagation. The predicted spectrum of the sound pressure level observed at 1.2 m from the trailing edge of the airfoil is validated by comparing measurement data, and the results show that the simulation is able to capture the dominant frequency of the tonal peak. However, while the measured spectrum is more broadband, the predicted spectrum has the tonal character around the primary frequency. This difference can be considered to arise due to insufficient mesh resolution.

Published: August 2021

In the present study, chitosan oligomer was modified to sulfated chitosan oligomer (ShCsO) to mimic heparin. Its chemical structure was determined by infrared spectroscopy (FT-IR), X-ray diffractometry (XRD), differential scanning calorimetry (DSC), and thermogravimetric analysis. The results showed that the FT-IR spectrum band at 799 cm−1 corresponds to C–O–S and that at 1212 cm−1 corresponds to S=O bond stretching, which prove that the sulfate groups are incorporated into chitosan oligomer successfully. The antimicrobial activity of ShCsO against to Bacillus subtilis in 1% concentration was 89.1 ± 1.7% . The IC50 (μg/ml) of ShCsO was 67.75, 56.07, 85.47, and 84.68 for A2780, MCF-7, DU-145, and HepG2, respectively. The results show that this newly synthesized material is a potential candidate to heparin-like chitosan derivatives. According to the literature, it was the first time that chitosan oligomer was modified to mimic heparin.

Objective Nonsyndromic cleft lip and/or cleft palate (NSCL/P) have multifactorial etiology where genetic factors, gene–environment interactions, stochastic factors, gene–gene interactions, and parent-of-origin effects (POEs) play cardinal roles. POEs arise when the parental origin of alleles differentially impacts the phenotype of the offspring. The aim of this study was to identify POEs that can increase risk for NSCL/P in humans using a genome-wide dataset. Methods The samples (174 case-parent trios from Ghana, Ethiopia, and Nigeria) included in this study were from the African only genome wide association studies (GWAS) that was published in 2019. Genotyping of individual DNA using over 2 million multiethnic and African ancestry-specific single-nucleotide polymorphisms from the Illumina Multi-Ethnic Genotyping Array v2 15070954 A2 (genome build GRCh37/hg19) was done at the Center for Inherited Diseases Research. After quality control checks, PLINK was employed to carry out POE analysis employing the pooled subphenotypes of NSCL/P. Results We observed possible hints of POEs at a cluster of genes at a 1 mega base pair window at the major histocompatibility complex class 1 locus on chromosome 6, as well as at other loci encompassing candidate genes such as ASB18, ANKEF1, AGAP1, GABRD, HHAT, CCT7, DNMT3A, EPHA7, FOXO3, lncRNAs, microRNA, antisense RNAs, ZNRD1, ZFAT, and ZBTB16. Conclusion Findings from our study suggest that some loci may increase the risk for NSCL/P through POEs. Additional studies are required to confirm these suggestive loci in NSCL/P etiology.
