Authors: Morikawa Mamoru , Saito Yoshihiro , Mayama Michinori , Noshiro Kiwamu , Nakagawa‐Akabane Kinuko , Umazume Takeshi , Chiba Kentaro , Watari Hidemichi
Published: July 2021

Aim

To investigate the relationship between excessive gestational weight gain during the week prior to delivery (GWG) and severe morbidity and pregnancy termination among pregnant women with preeclampsia (hypertension with proteinuria).

Methods

We compared GWG, laboratory data, and complication(s) between 94 preeclamptic women (preeclampsia group) with singleton pregnancies who delivered at ≥22 gestational weeks and 188 healthy women (control group) with singleton pregnancies undergoing elective cesarean deliveries. The gestational weeks at delivery were matched in the preeclampsia and control groups.

Results

Among 282 total participants, median of GWG was significantly higher in the preeclampsia group than in the control group (1.6 kg vs. 0.5 kg, p < 0.0001). Furthermore, the GWG cutoff value for the preeclampsia group was 1.6 kg. The odds ratio for morbidity of preeclampsia among the women with GWG ≥1.6 kg at delivery was 12.5 (95% confidence interval, 6.31–24.5). In the preeclampsia group, 47 women with GWG ≥1.6 kg had significantly higher risks of hypoproteinemia, proteinuria, and renal dysfunction than those of 47 women with GWG < 1.6 kg. While, multivariate analysis showed 1.5 kg was a GWG cutoff value for predicting maternal morbidity (p < 0.0001); preeclamptic women with GWG ≥1.5 kg had a significantly higher risk of pulmonary edema than preeclamptic women with GWG < 1.5 kg (odds ratio, 7.77; 95% confidence interval, 1.64–36.7).

Conclusion

Excessive GWG in women with preeclampsia might be a predictor for severe maternal life‐threatening complications requiring pregnancy termination.

Published: July 2021

Aim

To examine the structural and functional changes of the fetal heart in gestational diabetes mellitus (GDM) and to evaluate the power of fetal cardiac Doppler parameters in predicting adverse perinatal outcomes in this group of pregnancy.

Methods

Within the study's scope, 36 cases in the A1 GDM group, 33 cases in the A2 GDM group, and 124 cases in the control group were evaluated. The relationship between structural and functional fetal cardiac parameters and perinatal outcomes was evaluated via fetal echocardiography.

Results

Fetal left ventricular myocardial performance index (MPI) values were found to be statistically significantly higher when compared between the A1 GDM and A2 GDM groups and the control group (p= 0.000 andp= 0.000, respectively), while the E/A ratio was found to be significantly lower (p= 0.000 andp= 0.000, respectively). It was determined that the maternal blood HbA1c level showed a significant negative correlation with the fetal cardiac E/A ratio and a significant positive correlation with isovolumetric relaxation time and MPI (p= 0.000,p= 0.000, andp= 0.000, respectively). Adverse perinatal outcome rate was higher in the diabetic group (46.4%–22.6%). When the cases with GDM were examined in terms of perinatal outcomes, it was observed that there was a significant difference in HbA1c levels, E/A ratio, and MPI values between the cases in the group with adverse perinatal outcomes and the group with normal results (p= 0.001,p= 0.000, andp= 0.000, respectively).

Conclusions

The strong relationship between abnormal cardiac function and adverse perinatal outcomes suggest that cardiac Doppler may be a valuable tool for fetal monitoring and management for the GDM patient group.
Why is Distance Important for Hospital Choice? Separating Home Bias From Transport Costs*
Authors: Raval Devesh , Rosenbaum Ted
Published: July 2021

In retail and health care markets, demand declines with geographic distance to the establishment, but either transport costs or preferences correlated with distance (‘home bias’) could cause this decline. Using hospital choices for childbirth, we find that, after controlling for home bias using fixed effects, estimates of the transport cost disutility fall by 40% relative to a standard logit model. We show that referrals are a likely source of home bias. We then show that home bias matters for policy questions including a simulated hospital merger, network adequacy concerns, and the tradeoff between distance and quality.
A New Approach to Estimating State Dependence in Consumers’ Brand Choices Applied to 762 Pharmaceutical Markets*
Authors: Granlund David
Published: July 2021

This article shows how state dependence effects can be estimated for many markets and with few assumptions by using data on how the shares of consumers buying specific products differ between those who bought the same product on their latest purchase occasion and those who did not. Using information regarding which product was cheapest when consumers made their last purchases as instrument, I estimate that state dependence increases the probability that consumers will buy the product they bought the last time by eight percentage points. This effect is larger for women and the elderly than for men and younger consumers.
Conducting a Netnography in Second Language Acquisition Research
Authors: Kessler Matt , De Costa Peter , Isbell Daniel R. , Gajasinghe Kasun
Published: July 2021

In this Methods Showcase Article, we highlight a qualitative research methodology called netnography, an adaptation of ethnography and ethnographic methods applied to researching digital/online communities. We briefly discuss how netnography has evolved from its origins in the fields of consumer research and marketing to its more recent applications in the field of second language acquisition (SLA) for exploring phenomena related to online language teaching and learning. Next, we focus on the specific methods and techniques associated with conducting a netnography, and we propose numerous considerations for SLA researchers who wish to adopt the methodology in future studies. These considerations include various issues such as the recruitment of research participants (e.g., obtaining consent), researcher positioning (e.g., emic perspectives, ethics), the analysis of online multimodal data, and general reporting practices (e.g., protecting participants’ identities). Finally, we close with specific recommendations for future research directions.
Interaction between decadal‐to‐multidecadal oceanic variability and sudden stratospheric warmings
Authors: Ayarzagüena Blanca , Manzini Elisa , Calvo Natalia , Matei Daniela
Published: July 2021

Major sudden stratospheric warmings (SSWs) are the most important phenomena of the wintertime boreal stratospheric variability. During SSWs, the polar temperature increases abruptly, and easterlies prevail in the stratosphere. Their effects extend farther from the polar stratosphere, affecting near‐surface circulation. According to observations, SSWs are not equally distributed in time, with decades experiencing very few events, while others experiencing SSWs almost every winter. Some sources of this SSW multidecadal variability can be traced back to sea surface temperature changes. Here, we investigate the effects of Pacific decadal variability (PDV) and Atlantic multidecadal variability (AMV) on SSWs. We use for the first time a large ensemble of historical experiments to examine the modulation of the frequency, tropospheric precursors, and impact of SSWs by the PDV and AMV. We find a strong impact of the PDV on the occurrence of SSWs, with a higher SSW frequency for the positive phase of the PDV. This PDV influence is mediated by constructive interference of PDV anomalies with tropospheric stationary waves. The main effect of AMV is, instead, a modulation of the tropospheric response to SSWs, a finding that can be useful for predicting the tropospheric fingerprint of SSWs.
Is Tai Chi an effective intervention for enhancing health‐related quality of life in older people with mild cognitive impairment? An interventional study
Authors: Siu Mei‐yi , Lee Diana T. F.
Published: July 2021

Background

Many neuropsychiatric symptoms in persons of MCI cause negative impacts on their HRQOL. There is limited HRQOL research investigating the effect of Tai Chi on older people with MCI.

Objective

To determine the effectiveness of a Tai Chi program in enhancing health‐related quality of life (HRQOL) among community‐dwelling older people with mild cognitive impairment (MCI) in Hong Kong.

Methods

This was a quasi‐experimental study using a nonequivalent control group (CG) design. Four social centres for older people participated in the study, of which two centres were randomised for Tai Chi intervention and the other two were treated as control. Participants in the intervention group (IG) were arranged for a 1‐hour Tai Chi class twice weekly for 16 weeks, whereas participants in the CG were advised to join various recreational activities in the social centres as usual. For outcome evaluation, the Chinese version of the Short Form‐12 Health Survey‐Standard 1 (SF‐12) was employed to assess participants’ perceived HRQOL.

Results

One hundred and sixty participants were recruited (IG = 80, CG = 80). Data were collected at baseline (T0) and 16‐week post‐intervention (T1).The IG reported significant improvement in the physical health component (PCS) (p = .036), the mental health component (MCS) (p = .014), as well as several subscales of SF‐12, namely, the role‐physical (RP) (p = .044), the bodily pain (BP) (p < .001) and the vitality (VT) (p = .004) subscales, in comparison with the CG.

Conclusion

The current study results extended our knowledge about Tai Chi of which the mind‐body exercise could enhance the physical and psychosocial well‐being in older people with MCI.

Implications for practice

The findings have the potential to inform health and social care professionals to promote Tai Chi in community settings, as it may represent a non‐intensive and age‐fitting strategy to promote HRQOL in older people with MCI.

A pyruvate kinase deficiency child with novel PK‐LR gene mutations was successfully cured by matched unrelated donor peripheral blood stem cell transplantation
Authors: Zhan Li‐ping , Que Li‐ping , Wu Zheng‐zhou , Liu Dian‐dian , Wang Kai‐mei , Xu Hong‐gui , Fang Jian‐pei , Huang Ke
Published: July 2021

Background

Pyruvate kinase deficiency (PKD) is an autosomal recessive disorder caused by a PK‐LR gene mutation. Allogeneic hematopoietic cell transplantation (HCT) is an effective cure for PKD. However, the experience of applying HCT in PKD is limited.

Methods

We present a child with novel PK‐LR gene mutations who was successfully cured by matched unrelated donor peripheral blood stem cell transplantation (MUD‐PBSCT).

Results

A 4‐year‐old, male patient suffered severe hemolytic anemia and jaundice 5 h after birth. Gene sequencing showed that the pyruvate kinase‐liver and RBC (PK‐LR) gene had a nonsense mutation in exon 5: c.602G>A (p.W201X), and large deletions in exons 3–9. Both of them were novel pathogenic mutations of the PK‐LR gene. After transplantation, the hemoglobin level became normal and the nonsense mutation was undetectable. Grade Ⅳ acute graft‐versus‐host disease (aGVHD) and extensive chronic graft‐versus‐host disease (cGVHD) occurred in the patient. However, the GVHD was controlled effectively. The patient is alive and has good quality of life 22 months post‐transplant, but has mild oral lichen planus‐like lesion.

Conclusion

Gene sequencing contributes to the diagnosis of PKD. HCT is an effective method for curing PKD, but we should explore how to reduce severe GVHD.
Early postnatal growth and subsequent neurodevelopment in children delivered at term: The ELFE cohort study
Authors: Taine Marion , Forhan Anne , Morgan Andrei S. , Bernard Jonathan Y. , Peyre Hugo , Dufourg Marie‐Noëlle , Martin Laetitia Marchand , Charles Marie‐Aline , Botton Jérémie , Heude Barbara
Published: July 2021

Background

Despite the limited evidence, accelerated early postnatal growth (EPG) is commonly believed to benefit neurodevelopment for term‐born infants, especially those small for gestational age.

Objectives

To investigate the existence of critical time windows in the association of EPG with neurodevelopment, considering birth size groups.

Study design

In the French ELFE birth cohort, 12,854 term‐born neonates were classified as small, appropriate or large for gestational age (SGA, AGA, LGA, respectively). Parents reported their child's development by using the Child Development Inventory (CDI‐score) at age 12 months and the MacArthur‐Bates Development Inventory (MAB‐score; 100 score units) assessing language ability at age 24 months. Predictions of individual weight, body mass index (BMI), length, and head circumference (HC) from birth to age 24 months were obtained from repeated measurements fitted with the Jenss‐Bayley mixed‐effects model. For each infant, conditional gains (CG) in these growth parameters were generated at four‐time points (3, 6, 12 and 24 months) representing specific variations in growth parameters during 0–3, 3–6, 6–12, 12–24 months, independent of previous measures. Using multivariable linear regression models, we provided the estimate differences of the neurodevelopmental scores according to variation of each growth parameter CG, by birth size group.

Results

For SGA infants, the MAB‐score differed by 5.8 (95% confidence interval [CI] −0.2, 11.8), 6.7 (95% CI −0.1, 13.3), and 9.7 (95% CI 1.9, 17.5) score units when CG in BMI, weight, and HC at 3 months varied from −2 to 1 standard deviation, respectively. For all infants, MAB‐score was linearly and positively associated with length conditional gains at 12 months, with stronger magnitude for SGA infants. Results for the CDI‐score were overall consistent with those for MAB‐score.

Conclusions

For term‐born SGA infants, moderate catch‐up in HC, BMI and weight within the first 3 months of life may benefit later neurodevelopment, which could guide clinicians to monitor EPG.
A Systematic Literature Review of Empirical Research on the Impacts of e‐Government: A Public Value Perspective
Authors: MacLean Don , Titah Ryad
Published: July 2021

While government organizations continue to invest in e‐Government systems, there is still uncertainty as to the benefits that can be generated. Without clear expectations, it will be impossible for managers to measure and evaluate outcomes. This systematic literature review examines 60 empirical studies on the impacts of e‐Government published in the leading public administration and information systems journals. The impacts are classified using public value theory, first, by the role for whom value is generated and, second, by the nature of the impact. The results show that the most commonly studied impacts are productivity for the taxpayers and clients, client satisfaction and service quality for clients, and improved trust and communications for citizens. There are many areas where limited research has been conducted. We maintain that there is a complex network of immediate and indirect impacts that must be considered by public managers in their analysis of potential investments.
Exposing the Unfinished Business of Building Public Administration in Late Democracies: Lessons from the COVID‐19 Response in Brazil
Authors: Puppim de Oliveira Jose A. , Berman Evan M.
Published: July 2021

The COVID‐19 pandemic has exposed fundamental flaws in the design of public administration in late democracies. While much writing to date focuses on the initial and vital responses to COVID‐19, the magnitude of this event also furthers insights into the risks of incomplete institutional designs and practices, such as the case of Brazil, an example of the administrative flaws in late democracies. This article is not a critique of responses to COVID‐19 per se, but an examination of these considering democratization processes that include state‐building and the need for another push in administrative and political reforms. Shortcomings in state‐building, which existed before COVID‐19, inflict heavy costs on society and, if left unaddressed, add to the costs of future disasters and unraveling of support for state and democratic institutions.
Proximal correlates of suicidal ideation among transgender and gender diverse people: A preliminary test of the three‐step theory
Authors: Wolford‐Clevenger Caitlin , Flores Leticia Y. , Stuart Gregory L.
Published: July 2021

Introduction

Transgender and gender diverse (TGD) people experience higher rates of suicidal ideation than their cisgender peers; however, very little is known about factors that proximally relate to suicidal ideation in this population. This limited understanding may be due to the lack of theory‐guided studies that are capable of testing proximal correlates of suicidal ideation among TGD people.

Methods

We tested the first two steps of the three‐step theory (3ST) of suicide using daily survey data from a sample of 38 TGD people over 30 days.

Results

A total of 836 daily surveys were collected (73.3% compliance). Multilevel modeling supported the first and second step of the 3ST. Psychological pain and hopelessness interacted to predict same‐day suicidal ideation, with psychological pain positively associating with ideation only at average and high levels of hopelessness. Furthermore, psychological pain that outweighed connectedness was moderately associated with suicidal ideation among those with high levels of hopelessness and psychological pain.

Conclusion

The 3ST of suicide shows promise for explaining and guiding interventions to reduce suicidal ideation in this vulnerable population.
Peer persuasion strategies during rule following in 4‐ to 6‐year‐olds
Authors: Şen Hilal H. , Küntay Aylin C. , Kumkale Tarcan G.
Published: July 2021

Despite being a ubiquitous form of communication, persuasive communication between children received relatively scant research attention. We used a novel approach to study children's persuasive interactions in a semi‐naturalistic paradigm where dyads of 4‐ to 6‐year‐old children were asked to follow a rule together. In this context, we observed (a) the frequency and types of strategies children spontaneously used to persuade their partners to abide by the rule, (b) compliance behavior following the persuasion attempt, and (c) strategy change following a failed attempt to persuade. We coded children's persuasive strategies as gentle control, negative control, and non‐engagement. Children tended to use gentle control and negative control strategies to a greater extent than non‐engagement strategies to prevent their partner's potential rule violation. However, after a violation occurred, children most frequently displayed non‐engagement. Gentle control brought about more compliance than the other strategies. Children tended to maintain their persuasive strategy of negative control and non‐engagement, even though these were mostly ineffective in achieving compliance. These results show that 4‐ to 6‐year‐old children spontaneously and flexibly utilized persuasive strategies with peers to abide by a rule.
Frontline social service as a battlefield: Insights from street‐level bureaucrats' interactions with violent clients
Authors: Davidovitz Maayan , Cohen Nissim
Published: July 2021

How do different types of social service providers experience and respond to violent clients? The street‐level social service environment is a fertile ground for manifestations of violence by dissatisfied clients. This study examines the violence, verbal, and physical, to which street‐level bureaucrats are exposed, and the different coping strategies they adopt. We explore these issues using interviews with 71 Israeli social service providers. Our results indicate that while some street‐level bureaucrats are tolerant of client violence, others refuse to accept it. The former weigh their words, express empathy and seek to satisfy demands. The latter recruit the support of additional players and server relationships.

The Underappreciated Effects of Unreliability on Multiple Regression and Mediation
Authors: Trafimow David
Published: July 2021

There is an increasing trend for researchers in the social sciences to draw causal conclusions from correlational data. Even researchers who use relatively causally neutral language in describing their findings, imply causation by including diagrams with arrows. Moreover, they typically make recommendations for intervention or other applications in their discussion sections, that would make no sense without an implicit assumption that the findings really do indicate causal pathways. The present manuscript commences with the generous assumption that regression-based procedures extract causation out of correlational data, with an exploration of the surprising effects of unreliability on causal conclusions. After discussing the pros and cons of correcting for unreliability, the generous assumption is questioned too. The conclusion is that researchers should be more cautious in interpreting findings based on correlational research paradigms.
Redención americana: esquirlas del imaginario paradisiaco en la representación del Nuevo Mundo y sus habitantes “originarios”
Authors: Torres Jorge Esteban
Published: July 2021

En el presente texto indago sobre la incidencia del imaginario del paraíso terrenal, propio de la tradición judeocristiana, en el proceso colonizador de América. La aseveración de un Edén en tierras americanas se decantó en la intención – acción de los colonizadores que varía constantemente según la línea ideológica desde la que estos se acercan al paraíso. En consecuencia, al tratarse de un problema propio del imaginario, se abordarán las fuentes tanto de la cultura visual como de la cultura literaria de la época buscando recrear la atmósfera de credulidad y fe en que se gestó el proceso colonizador.

Es de mi particular interés desentrañar tres consecuencias de estar siendo el paraíso que se encuentran vigentes en el territorio americano, a saber: La ideología del paisaje, la decantación de las condiciones del territorio en sus habitantes (siguiendo a Norton, 1993) y la tensión entre ser un lugar del hedonismo (abundante y abierto) y, a la vez, un lugar de la dificultad (salvaje y riesgoso). Considero que indagar las implicaciones del paraíso en el territorio americano y en sus habitantes, podría contribuir a la revisión crítica sobre la representación, conceptualización y narración que nos identifica hasta el día de hoy. Vernos tal cuál somos, continuando con la pregunta que inicia Gayatri Spivak en ¿Puede hablar el subalterno? (1988), es mi principal intención en las páginas que usted está por leer y en la investigación en curso.
Shekuita o el mal trueno: documental performativo, conflictos ontológicos y descolonización de lo real
Authors: Valencia Rincón Juan Carlos , Restrepo Hoyos Paula Andrea
Published: July 2021

Este artículo analiza las implicaciones ontológicas y el carácter performativo del documental Shekuita o el mal trueno, lanzado en 2017 por un colectivo de producción audio- visual indígena wiwa en la Sierra Nevada de Santa Marta en Colombia. El documental explora las causas, dudas y consecuencias de un triste incidente ocurrido tres años antes: la caída de un rayo sobre una edificación ceremonial de los wiwas, que causó la muerte a casi una docena de líderes. A partir del contraste entre las explicaciones científicas de la tragedia y las que han investigado las autoridades espirituales de la comunidad desde sus ontologías relacionales, y basándonos en un trabajo de campo cuasietnográfico durante el proceso de filmación, buscamos dar cuenta de un caso específico de descolonización de lo real y de los esfuerzos de una comunidad indígena por la libre expresión y la representación autónoma. Encontramos que este documental abre puertas de forma artística a mundos otros, contados en clave insumisa desde una indigenidad que nos interpela. Concluimos que los wiwas performan un realidad que no necesariamente es la que vivieron, sino una que les permite estratégicamente alcanzar más fácilmente la realidad que quieren recuperar. El artículo intenta contribuir a la visibilización de otras ontologías distintas de la naturalista, a mostrar las autocríticas de esta y a manifestar cómo el audiovisual es un espacio propicio para descolonizar lo real.

Published: July 2021

The application of the oxy-fuel combustion technique could tackle the combustion process's environmental issues. Experiments were conducted on partially premixed air- and oxy-methane combustion flames stabilized over a novel perforated burner in the present work. The burner has a premixing ratio of 7.0. In oxy-fuel combustion, the experiments were performed at oxygen fractions (OF%: volumetric percentage of O2 in the oxidizer mixture) of 29%, 32%, and 36% and over a range of operating conditions necessary for a stable flame. The results of oxy-combustion flames were compared with the corresponding air-combustion flames at the same operating conditions. Two sets of statistical analyses were performed for further confirmation of the experimental results. The first set investigated the operating parameters’ effect, including OF and oxidizer Reynolds number (Re), on the upper flammability limits (UFL). Simultaneously, the second set studied the impact of OF and equivalence ratio on flame length. The experimental results revealed that the flammability limits get wider as the OF increases due to the resulting flame speed rise with O2-enrichment. The statistical analysis is conducted by analysis of variance (ANOVA) technique, which carries innovation and confirms that OF and Re significantly impacted the UFL. The visual flame length of oxy-flames was longer than its correspondents of air-flames due to the reduction of flame speed associated with the negative influence of CO2 dilution in oxy-flames. The statistical analysis showed a significant effect of OF and equivalence ratio on the visible flame appearance.
A piezoelectric micro-cantilever acoustic vector sensor designed considering fluid–structure interaction
Authors: Kim Junsoo , Yang Seongkwan , Oh Keunha , Moon Wonkyu
Published: July 2021

We developed a piezoelectric micromachined cantilever acoustic vector (PEMCAV) sensor. We modeled the device using a “lumped” approach that considers fluid–structure interaction, the piezoelectric effect, and the mechanical impedance of the cantilever. Due to the high flexibility, the influence of the medium is significant, so fluid–structure interaction must be considered in theoretical modeling. We compared the model data to experimental results. The design parameters optimized using the derived analytical open-circuit sensitivity equation are presented, and the physical characteristics of the sensor are discussed. We used a micromachining technique to fabricate the sensor, added a preamplifier, and tested it using a reference hydrophone under a frequency range of 100 Hz–1 kHz. The analytical predictions and experimental results were in good agreement with respect to frequency response and the directivity of the sensor. Even when the sensor was much smaller than the wavelength (ka≪1), the proposed sensor exhibited a typical cosine directivity pattern, and the measured sensitivity at 100 Hz was −194 dBV/μPa.

Published: July 2021

Coaching in elite sports can be a highly volatile and stressful profession. Nevertheless, limited knowledge is available on how coach stressors impact elite-level coaches’ mental health. The present study therefore aimed to assess the self-perceived impact of coach stressors on coaches’ mental health, in terms of psychological and social well-being, as well as the prevalence of symptoms of a number of common mental disorders. Furthermore, the role of resilience was examined as a potential protective resource against mental health issues in coaches. Data were collected cross-sectionally, using an online survey with 119 elite-level coaches from the Netherlands and Belgium. Results showed that, although coach stressors were commonly experienced, the self-perceived impact on mental health was low to moderate. Nevertheless, symptoms of common mental disorders were prevalent within the coaches, ranging from 39% for depression/anxiety to 19% for distress and adverse alcohol use. Furthermore, organizational stressors were found to be a positive predictor for symptoms of depression/anxiety, whereas resilience was a negative predictor. The results highlight the need for more research and attention to the mental health of coaches in elite sports.

Published: July 2021

There is an increasing awareness of the importance of the environment in academy players’ development, yet limited research has investigated players’ perceptions of their talent development environments (TDEs). This study focused on academy soccer players’ perceptions of their TDE and compared perceptions across the English soccer academy categorization (CAT) system. A total of 136 U.K.-based male soccer players (Mage = 17.7,SD = 1.03 years) representing all four categories (1 = highestto 4 = lowest) of soccer academies aligned to professional soccer clubs completed the TDE Questionnaire-5 (TDEQ-5). The players within the CAT1 academies had significantly more positive perceptions of their support network (p = .01) and holistic quality preparation (p = .03) than their CAT3 counterparts. Across CAT2–CAT3, holistic quality preparation was the least positively perceived subscale within the TDEQ-5, suggesting the need for additional coach education in this area. Soccer academies should consider how they ensure that all areas of their service are associated with optimal TDEs by offering a well-communicated and holistic development experience for their players to enhance effective personal and player development. The findings may have implications for player experience and associated progression rates of lower categorized soccer academies.

Scarce data exist about the coinfection of SARS‐CoV‐2 andMycobacterium tuberculosis(MTB). A young woman who was undergoing treatment for multiple sclerosis was brought to our hospital with a COVID-19 positive status. On further evaluation, her chest X-ray showed right upper and mid-zone opacity, which lead to the suspicion of MTB. Her sputum came positive for acid-fast bacilli (AFB) staining and cartridge-based nucleic acid amplification test (CBNAAT) confirmed it, and rifampicin resistance was not detected. She was started on an antitubercular regimen. She was discharged, and by the end of the intensive phase of treatment, her symptoms subsided, but her sputum CBNAAT still showed the presence of TB bacillus.
Diagnostic dilemma of isolated fallopian tube torsion

Paratubal cysts are fluid-filled sacs that grow adjacent to the fallopian tube which can rarely result in torsion. Isolated fallopian tube torsion (IFTT) is a gynaecological emergency that warrants urgent laparoscopic detorsion to salvage the affected tube. IFTT has a proclivity to affect adolescents between the ages of 12 and 15 years and is rarely seen in premenarchal or perimenopausal women. Due to a lack of pathognomonical features, IFTT is difficult to diagnose. Adnexal torsion, including IFTT is a surgical diagnosis and no clinical or imaging criteria is sufficient to diagnose IFTT. Urgent laparoscopy and detorsion are required for preservation of the affected fallopian tube. However, given the diagnostic ambiguity, IFTT diagnosis is often delayed. IFTT should be included in the differential diagnoses for adolescent patients with acute abdomen when imaging demonstrates a normal appendix and ovaries. We report a 15-year-old girl with a 4-day history of abdominopelvic pain and bilateral paratubal cysts resulting in right IFTT.
Unique triad of shunts in a patient with paroxysmal palpitations!

Published: July 2021

We present the case of a 34-year-old woman with a rare constellation of congenital cardiovascular defects. She presented with new-onset dyspnoea on exertion and intermittent palpitations. Extensive cardiac workup revealed anomalous drainage of the inferior vena cava and a large secundum atrial septal defect. She underwent surgical repair. Intraoperatively, an additional congenital venous anomaly was discovered, a partial anomalous pulmonary venous connection. Specifically, the right inferior pulmonary vein connected to the inferior vena cava, and together, they drained into the left atrium. On conducting a thorough literature review, we believe this is the first reported case in an adult female.

Atlantic salmon (Salmo salar) are increasingly being released after capture by anglers. Yet, there are still unknown effects on the fish being subjected to the process of catch and release. Capture too close to spawning could have adverse effects on fish, and such data are important for setting appropriate closed seasons. This study examines how stressors related to catch and release experienced shortly before spawning affects adult mortality, vulnerability to Saprolegnia spp., and reproductive traits. Adult salmon were collected from the river Blackwater, Scotland, towards the end of their migration and were exposed to one of four protocols comprising exercise and air exposure of different durations. The experimental stressors increased the growth rate of the fungus Saprolegnia spp. over the body of the fish. Moreover, male salmon from the most disturbed group exhibited an increase in the maximum duration of their sperm motility. Lastly, females that experienced exercise and (or) air exposure spawned at the usual time but with fewer eggs. These suggest that there may be benefits from preventing angling close to the time of spawning.
Effect of Hall current on the flow and heat transfer of non-Newtonian power-law nanofluid in the presence of Cattaneo–Christov heat flux and free stream
Authors: El-Aziz Mohamed Abd , Aly Abdelraheem M.
Published: July 2021

The nanofluids are a recent challenging task in a nanotechnology field used in heat transfer enhancement for base fluids. The major purpose of this research is to examine the influences of Hall current on the non-Newtonian power-law nanofluid on an exponentially extending surface. Implementation in the Cattaneo–Christov heat flux and the free stream is performed to analyze the thermal relaxation features. Entropy generation evaluation and Bejan number during the convection flow are investigated. The Runge–Kutta–Fehlberg method is employed to resolve the transformed governing nonlinear equations. The impacts of the key physical factors on the profiles of primary and secondary velocities, temperature and entropy generation are discussed across the graphs. The local skin-friction coefficients, Nusselt and Sherwood numbers are demonstrated in a tabular form under the impacts of key physical parameters. Two different types of power-law indicators including pseudoplastic fluid [Formula: see text] and dilatant fluid [Formula: see text] are conducted. The results indicated that the flow speed decreases at dilatant fluid compared to pseudoplastic fluid due to higher viscosity. Increasing Hall current parameter powers the axial and secondary velocity profiles. Thermophoresis parameter powers the profiles of the temperature, nanoparticle volume fraction and local entropy generation. The dilatant fluid [Formula: see text] gives higher values of [Formula: see text] and [Formula: see text] compared to the pseudoplastic fluid [Formula: see text].
LICENSING BY OUTSIDE INNOVATOR IN HOTELLING MODEL REVISITED

Published: July 2021

This paper extends Banerjee and Poddar [Banerjee, S and S Poddar (2019). ‘To sell or not to sell’: Licensing versus selling by an outside innovator. Economic Modelling, 76, 293–304] by lifting the cap on per unit royalty rates in the cases of royalty licensing and two-part tariff licensing. We reconsider the optimal technology licensing contract by an outside innovator facing two heterogeneous licensees in a standard Hotelling framework. Our findings show that the optimal licensing policy could be fixed fee to the efficient firm, or two-part tariff to both firms (pure royalty to both firms), or two-part tariff to the efficient firm, depending upon the cost differentials between the firms and the size of innovation.
EDPANs: Enhanced Dual Path Attention Networks for Single Image Super-Resolution
Authors: Cheng Guoan , Matsune Ai , Zang Huaijuan , Kurihara Toru , Zhan Shu
Published: July 2021

In this paper, we propose an enhanced dual path attention network (EDPAN) for image super-resolution. ResNet is good at implicitly reusing extracted features, DenseNet is good at exploring new features. Dual Path Network (DPN) combines ResNets and DenseNet to create a more accurate architecture than the straightforward one. We experimentally show that the residual network performs best when each block consists of two convolutions, and the dense network performs best when each micro-block consists of one convolution. Following these ideas, our EDPAN exploits the advantages of the residual structure and the dense structure. Besides, to deploy the computations for features more effectively, we introduce the attention mechanism into our EDPAN. Moreover, to relieve the parameters burden, we also utilize recursive learning to propose a lightweight model. In the experiments, we demonstrate the effectiveness and robustness of our proposed EDPAN on different degradation situations. The quantitative results and visualization comparison can sufficiently indicate that our EDPAN achieves favorable performance over the state-of-the-art frameworks.
Spatial Distribution of Ink at Keypoints (SDIK): A Novel Feature for Word Spotting in Arabic Documents

Published: July 2021

This paper addresses the challenging task of word spotting in Arabic handwritten documents. We proposed a novel feature that we called Spatial Distribution of Ink at Keypoints (SDIK). The proposed feature captures the characteristics of Arabic handwriting concentrated at endpoints and branch points. SDIK feature quantizes the spatial repartition of ink pixels in the neighborhoods of keypoints. The resulting SDIK features are very fast to match, we take this advantage to match a query word with lines images rather than words images. By this matching mechanism, we overcome the hard task of segmenting an Arabic document into words. The method proposed in this study is tested on historical Arabic document with IBN SINA dataset and on modern handwriting with IFN/ENIT database. The obtained results are great of interest for retrieving query words in an Arabic document.
Injective and projective semimodules over involutive semirings
Authors: Jipsen Peter , Vannucci Sara
Published: July 2021

We show that the term equivalence between MV-algebras and MV-semirings lifts to involutive residuated lattices and a class of semirings called involutive semirings. The semiring perspective leads to a necessary and sufficient condition for the interval [Formula: see text] to be a subalgebra of an involutive residuated lattice, where [Formula: see text] is the dualizing element. We also import some results and techniques of semimodule theory in the study of this class of semirings, generalizing results about injective and projective MV-semimodules. Indeed, we note that the involution plays a crucial role and that the results for MV-semirings are still true for involutive semirings whenever the Mundici functor is not involved. In particular, we prove that involution is a necessary and sufficient condition in order for projective and injective semimodules to coincide.
Thermodynamics of traversable wormholes in f(R,T) gravity
Authors: Rehman Mudassar , Saifullah Khalid
Published: July 2021

In this paper, we discuss thermodynamics for spherically symmetric and static traversable wormholes which include Morris–Thorne wormholes and charged wormholes in the background of [Formula: see text] gravity. The local coordinates have been used to find trapping horizons of these objects and generalized surface gravity has been worked out on the trapping horizons. The expression for the unified first law has also been derived from the gradient of Misner–Sharp energy with the help of gravitational field equations and from this law the first law of wormhole dynamics has been obtained. We have done this analysis for the simplest case of [Formula: see text] gravity where [Formula: see text], [Formula: see text] and [Formula: see text] being the traces of the Ricci and stress–energy tensors. Also, we have extended these thermodynamic results to non-minimal curvature-matter coupling.
