Menger’s precursors in the German subjective-value tradition and his advancements in the theory of wants and goods
Authors: Harper David A. , Endres Anthony M. 
Published: November 2022

AbstractMenger made wants and goods the center of economic analysis. This paper locates his theory of wants and goods in the history of economic ideas, identifying major influences from the German subjective-value tradition of the 19th century. Our survey of select German economists prior to 1871 – Hufeland, Storch, Rau, Hermann, Mischler, Stein and Schäffle – discovers insights that highlight the subjective and processual nature of the wants-goods nexus, as does Menger’s approach. Menger’s process approach to economics had several precursors – the historical record is much more nuanced than previously recognized. Menger combined existing ideas on wants and goods into a novel, more coherent and productive framework. He portrayed human wants and the desire to satisfy them as the driving force propelling economic processes. Menger’s theory about wants and goods provided the foundations for his theory of subjective value. He showed how the simple idea that people value goods in light of their wants is the key to the most fundamental problems of economic theory, including value, price formation, production, distribution and economic development, and he applied this insight to explain complex economic processes in modern market economies. Menger’s work constitutes a major synthesis that advances earlier ideas (especially of Hermann, Mischler and Schäffle) on wants, goods and their interplay, and his focus upon complementarities of consumer goods constitutes yet a further advancement on German economics.
Thalamic Aphasia: a Review
Authors: Fritsch Merve , Rangus Ida , Nolte Christian H. 
Published: November 2022

AbstractPurpose of ReviewThalamic aphasia is a rare language disorder resulting from lesions to the thalamus. While most patients exhibit mild symptoms with a predominance of lexical-semantic difficulties, variations in phenotype have been described. Overall, the exact mechanisms of thalamic aphasia await empirical research. The article reviews recent findings regarding phenotypes and possible underlying mechanisms of thalamic aphasia.Recent FindingsVariations in phenotype of thalamic aphasia may be related to different lesion locations. Overall, the thalamus’ role in language is thought to be due to its involvement in cortico-thalamic language networks with lesioning of certain nuclei resulting in the diachisis of otherwise interconnected areas. Its possible monitoring function in such a network might be due to its different cellular firing modes. However, no specific evidence has been collected to date.SummaryWhile recent findings show a more distinct understanding of thalamic aphasia phenotypes and possible underlying mechanisms, further research is needed. Additionally, as standard language testing might oftentimes not pick up on its subtle symptoms, thalamic aphasia might be underdiagnosed.
Deprivation in England, 1971–2020

Abstract
Measures of small area deprivation have played a major role in targeting resources in the UK. The English Index of Multiple Deprivation (IMD) is the official measure of small area deprivation in England and it has been used to allocate billions of pounds of government money. The success of schemes to reduce deprivation can only be assessed by measuring changes in deprivation over time. In addition, the effect of such schemes is likely to be a partly a function of the deprivation history of an area. More generally, the trajectory of deprivation, and not just its current state, is important in understanding the likely impacts of deprivation on those who live in deprived areas. This paper combines the strengths of the IMD as a broad-ranging measure based on administrative data (here, using the 2004, 2007, 2010, 2015 and 2019 indices) and the Townsend score derived from Census data for a much longer time period (1971 to 2011). In addition, benefit claimant count data are used as a proxy for unemployment following the national Covid-19 lockdowns. The paper identifies some major trends in small area deprivation and unemployment over the period 1971 to 2020 and it highlights some key similarities and differences between the Townsend score and the IMD and makes links to changes in unemployment in 2020. Areas with very long term deprivation are identified and the strong association between job losses following Covid-19 lockdown and deprivation histories is demonstrated. The analyses are used to argue that deprivation trajectories should be considered if effective strategies for reducing spatial inequalities are to be developed.

An investigation of aerodynamic behaviours and aerodynamic performance of a model wing formed from different profiles
Authors: Aşkan A. , Tangöz S. , Konar M. 
Published: November 2022

AbstractIn this study, the aerodynamic performances and the flow separation behaviour of the wing profiles, used in the wing of Boeing 737-Classic aircraft, and a model wing formed of these profiles were investigated at 2 × 105 Reynolds number (Re) and different angles of attack ranging from −4° to the angle, which maximum lift point obtained. The experiments were conducted in a low-speed wind tunnel in Erciyes University Faculty of Aeronautics and Astronautics Aerodynamic Laboratory. Four profiles and the model wing, which was obtained from the combination of the four profiles were produced in a rectangular shape with dimensions of 0.21m × 0.21m. In the first part of this two-part study, the wing profiles were examined individually regarding aerodynamic performance and flow separation. In the second phase of the study, the aerodynamic performance and the flow separation behaviour of the model wing were examined and the results were compared with the data obtained from each profile. The study results showed that the slopes of the numerical graphics are generally quite consistent with experimental results. In addition, the pressure and velocity distributions have followed the normal trend until the angle-of-attack (AoA) of 20°. In contrast, the negative speed values and negative pressure zones have appeared on the profile above this angle. The air flowed as laminar on the profiles and the model wing until 20°, while laminar separation bubbles are begun to take place at about 24° AoA. Finally, the best aerodynamic performance has been obtained with the model wing.

Abstract

Background:
Nowadays, the Covid-19 pandemic is 1 of the most important challenges worldwide, especially in terms of health. The most important strategy to prevent and control the Covid-19 pandemic is mass vaccination. This study aimed at developing a roadmap for the mass vaccination of COVID-19 in Iran.

Methods:
The current study was conducted using a qualitative approach with a content analysis method. In the first step, the review of literature and documents was carried out by a search in scientific databases. In the next step, the data were amassed via in-depth and semi-structured interviews with experts who were selected purposefully, including policymakers, health care workers, and managers. After this, 3 multidisciplinary expert panels for roadmap development were held.

Results:
Based on the literature review, interviews, and 3 stages of an expert panel, the final roadmap was developed with 5 dimensions. These included outcomes, planning and preparation, strategies, and preparation, implementation, monitoring, and evaluation.

Conclusions:
This roadmap was developed to improve mass vaccination during the COVID-19 pandemic. According to our findings, it is strongly recommended that the vaccination roadmap with all the above-mentioned features and comprehensive structure should be applied to mitigate the consequences of the COVID-19 pandemic.

AbstractHepatitis B virus (HBV) infection led to 66% liver deaths world-wide in year 2015. Thirty-seven per cent of these deaths were the result of chronic hepatitis B (CHB)-associated hepatocellular carcinoma (HCC). Although early diagnosis of HCC improves survival, early detection is rare. Methylation of HBV DNA including covalently closed circular DNA (cccDNA) is more often encountered in HCC cases than those in CHB and cirrhosis. Three typical CpG islands within the HBV genome are the common sites for methylation. The HBV cccDNA methylation affects the viral replication and protein expression in the course of infection and may associate with the disease pathogenesis and HCC development. We review the current findings in HBV DNA methylation that provide insights into its role in HCC diagnosis.

AbstractIn Bangladesh, only 34 % of the children aged 18–23 months old are given minimum acceptable diets of complementary foods. Objective of the study was to find the effects of complementary feeding counselling on nutritional status among 6–23 months old children of poor families. This was a community-based randomised control trial. A total of 192 children in two groups were randomly selected. Nutrition education was given for a period of 4 months with post-intervention follow-up for 2 months. After 4 months of intervention, the difference in height for age Z score, weight for height Z score and weight for age Z score were significantly higher in the intervention group than in the control group (1·01 ± 0·31 v. 0·19 ± 0·01, P =< 0·001; 1·34 ± 0·15 v 0·72 ± 0·11, P =< 0·001; 1·5 ± 0·24 v. 0·62 ± 0·04, P =< 0·001). Mid-upper arm circumference Z score also improved in the intervention group than in the control group (0·95 ± 0·03 v. 0·57 ± 0·12, P =< 0·001). Morbidity of the children in the intervention group significantly reduced than in the control group (49 % v 80·20 %, P =< 0·001). Higher feeding frequency (3–4 times) (71·9 % v. 45·8 %) and energy intake increased in the intervention group than in the control group. Promotion of complementary feeding from the family foods can improve the nutritional status of 6–23 months old children of poor families within a short period.
Endoscopic stapler versus laser diverticulotomy for Zenker's diverticulum: a systematic review and meta-analysis
Authors: Edwards D , Prades E , Thorne C , Harris A 
Published: November 2022

AbstractObjectiveA literature review and meta-analysis was performed to assess for difference in rate of complications and need for revision surgery between endoscopic stapler-assisted diverticulotomy and endoscopic carbon dioxide laser diverticulotomy. The hypothesis was that endoscopic stapler-assisted diverticulotomy has a lower complication rate but endoscopic carbon dioxide laser diverticulotomy has a lower need for revision surgery.MethodThis was a systematic review of English-language studies comparing endoscopic stapler-assisted diverticulotomy and endoscopic carbon dioxide laser diverticulotomy for the treatment of Zenker's diverticulum. Meta-analysis of results with regard to rate of pharyngeal perforation, major post-operative complication and need for re-operation was performed.ResultsNine retrospective studies were included with pooled analysis of 417 endoscopic stapler-assisted diverticulotomy and 413 endoscopic carbon dioxide laser diverticulotomy cases. Meta-analysis found no significant difference in rate of pharyngeal perforation, major complication or need for re-operation between the two groups.ConclusionThis study demonstrated both endoscopic stapler-assisted diverticulotomy and endoscopic carbon dioxide laser diverticulotomy to be a safe alternative to open surgery for Zenker's diverticulum. Both appear to be similar in terms of adverse events and efficacy. The authors recommend either approach, guided by surgeon's preference and experience, where patients are unsuitable for an open surgery approach.
Monks and the Muslim Enemy: Conversion, Polemic and Resistance in Monastic Hagiography in the Age of the Crusades, c. 1000–1250
Authors: Jotischky Andrew 
Published: November 2022

AbstractAlthough most accounts of Christian encounters with Muslims in the period between the eleventh and thirteenth centuries pay particular attention to conflict and violence, a body of hagiographical texts emanating from monastic circles points to a different kind of approach. In this article I foreground three examples of Italo-Greek saints’ lives from the tenth and early eleventh centuries in which the saints in question treat Muslims whom they encounter as potential converts, and explain to them the tenets of Christian theology. These texts are examined as precursors of the Cluniac ‘dossier’ compiled about Abbot Maiolus's encounter with Muslims in the 990s. Two of the three saints’ lives were translated from Greek into Latin, one in the late eleventh, the other in the late twelfth century. The motives for and circumstances of these translations are discussed in light of growing hostility towards the Islamic world during the period of the crusades.
A four-year multi-wave prospective study on the role of parental reflective functioning and parenting stress in the development of socio-emotional problems in internationally adopted children

Published: November 2022

AbstractParental reflective functioning (PRF) plays a protective role in the development of children with histories of early adversity, including adopted children. This is the first study to investigate the developmental trajectories of PRF and children’s socio-emotional problems in the first 4 years after international adoption (N = 48 families, mean age (T1) = 20.7 months) and to examine the mediating role of parenting stress in the relation between PRF and child socio-emotional problems. Multilevel modeling indicated that age at adoption and parent gender moderated the development of PRF and child socio-emotional problems. Moreover, decreases in PRF were associated with more socio-emotional problems in the children. These relations were mediated by parenting stress, and particularly feelings of incompetence and marital dissatisfaction.

AbstractBackground:During the COVID-19 pandemic, Kentucky prohibited elective medical procedures from 3/18/2020-4/27/2020. We sought to determine if cessation of elective procedures in Kentucky during the COVID-19 pandemic resulted in a decrease in the proportion of rarely appropriate outpatient transthoracic echocardiograms interpreted at the open echocardiography lab at Norton Children’s Hospital.Methods:A retrospective chart review was conducted comparing proportions of rarely appropriate outpatient paediatric transthoracic echocardiograms performed pre-COVID (3/21/2019-4/28/2019) and during COVID (3/19/2020-4/27/2020). Transthoracic echocardiogram indication was determined by chart review and echocardiogram reports. Indication appropriateness was evaluated using paediatric appropriate use criteria for initial outpatient transthoracic echocardiogram or CHD follow-up as applicable.Results:Of transthoracic echocardiograms pre-COVID, 100 (37.7%) were rarely appropriate versus 18 (20.2%) during COVID. Pre-COVID, paediatric cardiologists tended to order fewer rarely appropriate transthoracic echocardiograms than paediatricians (35.9% versus 46.4%), although this difference was not statistically significant. Cardiologists ordered the majority of outpatient transthoracic echocardiograms during COVID (77/89, 86.5%), limiting the ability to compare transthoracic echocardiogram indications by provider type. There was no significant difference in diagnostic yield of initial outpatient transthoracic echocardiograms with (13.0%) abnormal studies pre-COVID versus 7 (15.5%) during COVID.Conclusion:While elective procedures were prohibited in Kentucky during the COVID-19 pandemic, a decrease in the proportion of rarely appropriate outpatient paediatric transthoracic echocardiograms was observed. There was no significant difference in diagnostic yield of initial outpatient transthoracic echocardiograms between time periods, suggesting that clinically significant echocardiogram findings were still detected despite more prudent utilisation of echocardiography during this time.

AbstractHyperandrogenism is the most common endocrine disorder in women, characterized by an imbalance in normal estrogen and androgen levels in the blood. Androgens influence bone mineral density, body mass composition, muscle mass, mental state, and the regulation of sexual function.. The aim of the study was to assess the effect of estrogen receptor α gene (ESR1) polymorphisms on selected markers of bone metabolism and hormonal parameters in women with hyperandrogenism. The study group included 80 young women with hyperandrogenism who underwent measurements of bone mineral density (BMD), and determination of hormonal and metabolic parameters. Enzyme immunoassays were used to measure leptin, sRANKL (soluble receptor activator of nuclear factor-kB ligand), osteoprotegerin and 25-OH vitamin D total levels. An analysis of ESR1 gene polymorphisms was performed using the real-time PCR method. A relationship was demonstrated between the concentration of free estradiol (FEI) and the concentration of 17-OH-progesterone, and the ESR1 gene polymorphisms: rs3020314 (p = 0.031, p = 0.026 respectively) and rs1884051 (p = 0.033, p = 0.026 respectively). In conclusion, the ESR gene polymorphisms may be associated with hormonal disturbances in the concentration of estrogens and androgens, in hyperandrogenism in young women which may indirectly affect bone mineral density. However, no statistically significant relationships between the studied polymorphisms and the selected parameters of mineral metabolism have been demonstrated..

AbstractIn the scenario of global warming and pollution, the green synthesis and use of biodiesel has acquired utmost priority. Due to several limitations of homogeneous catalysis, organobase immobilized heterogeneous catalyzed production of biodiesel has come out as a favored route. The present report demonstrates the design and synthesis of Peganum harmala spice seed extract modified GO-CuFe2O4 (SSE@GO-CuFe2O4) nanocomposite as an organobase functionalized high surface area magnetic nanocatalyst. Pistachio leaves were used in the green reduction of precursor salts to synthesize CuFe2O4 NPs. The as-synthesized nanomaterial was characterized physicochemically by Fourier-transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), energy dispersive X-Ray analysis (EDX), elemental mapping, transmission electron microscopy (TEM), X-Ray diffraction (XRD), thermogravimetric analysis (TGA) and vibrating sample magnetometer techniques (VSM). Subsequently, the catalyst was explored in the efficient synthesis of biodiesels by trans-esterification of two substrates, the rapeseed oil and waste corn oil. The optimum conditions for biodiesel production were determined through response surface methodology based on Box–Behnken design including the study of calibration curves and 3D contour plots. Easy separation and workup, use of green medium, excellent reused for several times and short reaction time are outstanding benefits of this study.
Correlates of quality of life in South Korean patients undergoing hematopoietic stem cell transplantation based on the symptom management model

Published: November 2022

AbstractWhile hematopoietic stem cell transplantation (HSCT) has led to higher survival rates, the number of patients experiencing adverse reactions is also increasing. Based on the symptom management model, we aimed to analyze the relationships between symptom experience, symptom management strategies, self-management behavior, and quality of life among patients undergoing HSCT in South Korea and to identify the factors affecting their quality of life. The data of 67 conveniently sampled patients undergoing HSCT at a university-affiliated hospital, for the period from March 23 to June 7, 2016, were collected using a self-reported structured questionnaire. Data were analyzed using Pearson’s correlations and multiple regression analysis. Quality of life showed a significant negative correlation with symptom experience and significant positive correlations with symptom management strategies. Factors influencing quality of life included symptom distress, symptom management strategies, and self-management behavior; these explained 39.4% of the variance. To improve quality of life in patients undergoing HSCT, the efficient management of multiple co-existing symptoms is important. There is a need for tailored nursing interventions based on a patient-focused and person-centered approach for patients undergoing HSCT.
