AbstractAimTo 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.MethodsWithin 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.ResultsFetal 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).ConclusionsThe 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.

Published: July 2021

AbstractIn 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

Published: July 2021

AbstractMajor 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

AbstractBackgroundMany 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.ObjectiveTo 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.MethodsThis 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.ResultsOne 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.ConclusionThe 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 practiceThe 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.Trial registration: NCT03404765 (Retrospectively registered January 19, 2018).

AbstractBackgroundPyruvate 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.MethodsWe present a child with novel PK‐LR gene mutations who was successfully cured by matched unrelated donor peripheral blood stem cell transplantation (MUD‐PBSCT).ResultsA 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.ConclusionGene sequencing contributes to the diagnosis of PKD. HCT is an effective method for curing PKD, but we should explore how to reduce severe GVHD.

AbstractBackgroundDespite the limited evidence, accelerated early postnatal growth (EPG) is commonly believed to benefit neurodevelopment for term‐born infants, especially those small for gestational age.ObjectivesTo investigate the existence of critical time windows in the association of EPG with neurodevelopment, considering birth size groups.Study designIn 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.ResultsFor 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.ConclusionsFor 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

AbstractWhile 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

AbstractThe 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

AbstractIntroductionTransgender 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.MethodsWe 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.ResultsA 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.ConclusionThe 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

Published: July 2021

AbstractDespite 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

AbstractHow 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.
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.

Abstract
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.

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.
Civilizing the Past: Egyptian Irrigation in the Colonial Imagination
Authors: Haug Brendan 
Published: July 2021

Abstract
Reviews of the historiography of irrigation regularly single out Karl August Wittfogel’s “hydraulic hypothesis” as a uniquely deleterious contribution to the study of ancient water management. His errors notwithstanding, this article argues that the ideological misshaping of Western scholarship on irrigation instead emerged from Egypt’s long colonial experience. First articulated in the Napoleonic Description de l’Égypte, the theory of a centralized, ancient Egyptian “hydraulic state” was crafted to justify French attempts to reshape Egypt’s irrigated landscape. British hydraulic engineers later received and refined this narrative during the British colonial period. Their popularizing discourse retrojected the technocratic character of modern irrigation into antiquity, defining the Egyptian “irrigation system” as a static and unchanging fusion of hydraulic expertise and state power. Widely disseminated in specialist and popular fora, this tendentious argument had become received wisdom by the beginning of the twentieth century and subtly shaped early Egyptological descriptions of irrigation in antiquity.
The Riddle of the Tachat Family
Authors: Bělohoubková Dana 
Published: July 2021

Abstract
At the end of the Eighteenth and beginning of the Nineteenth Dynasty, several attestations of women named Tachat with the title wr.t ḫnr n jmn are possible to observe. These women all had a family background associated with service in the temple, mainly with the cult of Amun. This article brings these women together, and shows that the line of holders of this post in the Amun temple could imply the continuation of possible family ties among these female temple personnel. The family tree covers a rather long period of time for the women in question, who held this post in the cult of Amun even during the Amarna Period, demonstrating that some officials in Thebes were able to worship Amun even during the Amarna Period.
