Published: April 2023

AbstractWith the development of smart downhole control devices, such as the electric flow control valve (FCV), research on completion optimization using FCV control is gaining traction for successful field production management. Applying and verifying its applicability to actual assets with uncertain production issues occur are important. This study focuses on managing downhole devices to optimize fluid production in an actual onshore oil field in Alberta, Canada. The target field has been in production operation for over 20 years, and water flooding was used in the early stages of production to maintain reservoir pressure. However, according to the flow characteristics of the field, water injection caused a high water-cut issue due to water channeling. To mitigate the problem, proactive and reactive strategies were investigated to optimize FCV control. Additionally, the effect of completion optimization was estimated considering both the field-level economic value and the fluid production behavior at the device level. In most optimization cases, the cumulative water production could be reduced compared with the base case without valve control. Notably, the flow-balancing strategy increased the revenue of the target field by approximately 23 MM$ by maximizing oil production and suppressing water production. However, reactive and streamline-balancing strategies, which directly control and delay water production, undermined the economic value due to the decrease in oil production. The findings imply that FCV control strategy of suppressing only water production for the field with high water-cut could not be the optimal solution considering the reduction in oil production and the field’s revenue. The results of this study could be used as a reference to optimize downhole devices when applying water flooding in fields where high water-cut is expected.
Design of Agricultural Field Experiments Accounting for both Complex Blocking Structures and Network Effects

Published: April 2023

AbstractWe propose a novel model-based approach for constructing optimal designs with complex blocking structures and network effects for application in agricultural field experiments. The potential interference among treatments applied to different plots is described via a network structure, defined via the adjacency matrix. We consider a field trial run at Rothamsted Research and provide a comparison of optimal designs under various different models, specifically new network designs and the commonly used designs in such situations. It is shown that when there is interference between treatments on neighboring plots, designs incorporating network effects to model this interference are at least as efficient as, and often more efficient than, randomized row–column designs. In general, the advantage of network designs is that we can construct the neighbor structure even for an irregular layout by means of a graph to address the particular characteristics of the experiment. As we demonstrate through the motivating example, failing to account for the network structure when designing the experiment can lead to imprecise estimates of the treatment parameters and invalid conclusions.Supplementary materials accompanying this paper appear online.
„Derzeit mangels geeignetem Indikator nicht messbar“

Published: April 2023

ZusammenfassungUngeachtet der Tatsache, dass Österreich sich bereits 2016 zur Umsetzung der Sustainable Development Goals der UN bekannt hat, wurden weder geeignete Indikatoren festgelegt noch in systematische Datenerhebungen einbezogen, um die Umsetzung im Bildungsbereich, bezogen auf SDG 4.7, messbar zu machen. Die Autoren beschreiben internationale und nationale Ansätze, um zu aussagekräftigen Indikatoren zu kommen und erarbeiten Vorschläge, wie entsprechende Daten im österreichischen Kontext gewonnen werden können. Schließlich wird auf die Notwendigkeit hingewiesen, neben Output‑/Outcome-Indikatoren auch Prozessindikatoren zu entwickeln, da diese eine notwendige Voraussetzung sind, um die Qualität und das Kompetenzniveau in Bezug auf Bildung für nachhaltige Entwicklung in Österreich sichtbar zu machen.

Published: April 2023

AbstractFractional delay differential equations (FDDEs) and time-fractional delay partial differential equations (TFDPDEs) are the focus of the present research. The FDDEs is converted into a system of algebraic equations utilizing a novel numerical approach based on the spectral Galerkin (SG) technique. The suggested numerical technique is likewise utilized for TFDPDEs. In terms of shifted Jacobi polynomials, suitable trial functions are developed to fulfill the initial-boundary conditions of the main problems. According to the authors, this is the first time utilizing the SG technique to solve TFDPDEs. The approximate solution of five numerical examples is provided and compared with those of other approaches and with the analytic solutions to test the superiority of the proposed method.

Published: April 2023

Abstract
Introduction
Functional status is one of the most important issues of geriatric care. Polypharmacy seems to be a modifiable factor associated with functional decline in older adults. However, the impact of pharmacotherapy optimization on the activities of daily living in patients undergoing geriatric rehabilitation has not been investigated prospectively so far.

Methods
This post hoc analysis of a subsample of the VALFORTA study included individuals only undergoing geriatric rehabilitation with a length of in-hospital stay of at least 14 days. Medication was modified according to the FORTA rules in the intervention group while in the control group standard drug treatment was applied. Both groups received comprehensive geriatric treatment.

Results
The intervention and control groups consisted of 96 and 93 individuals respectively. They did not differ according to basic data except for age and Charlson Comorbidity Index (CCI) on admission. On discharge, activities of daily living (Barthel index, BI) were improved in both groups. An increase of at least 20 points of the BI was observed in 40% of patients in the intervention group and in 12% of patients in the control group (p< 0.001). Logistic regression analysis with an increase of at least 20 BI-points was significantly and independently associated with patient group (2.358, p< 0.02), BI on admission (0.957, p< 0.001), and the CCI (0.793, p< 0.041).

Conclusion
This post hoc analysis of a subsample of older individuals hospitalized for geriatric rehabilitation demonstrates a significant additional improvement in activities of daily living by modification of medication according to FORTA.

Published: April 2023

AbstractHot dip galvanizing is a surface treatment used to form a corrosion-resistant layer on the surface of steel by dipping it in a liquid zinc bath. However, a lot of structures used for hanging or containing the parts during the process are made of steel and suffer from liquid zinc corrosion. Furthermore, Fe–Zn intermetallics formed on the surface induce an additional pickling and zinc consummation, therefore generating supplementary economic and environmental costs. In this article, two Fe-Cr-Ni-Si coatings synthetized by the slurry process on carbon steel (C22) were characterized by XRD, EDX, EPMA and EBSD analyses. Their corrosion protective properties were studied in the process imitating cyclic batch galvanizing and compared to those of uncoated carbon steel (C22) and stainless steel (316 L). The coatings were verified to be more efficient than the 316 L steel usually used for this application. After 9 cycles of no weight loss, molten zinc corrosion was linear and the same for Fe-Cr-Ni-Si coatings as for the stainless steel.

AbstractMaize (Zea mays L.) is the most produced field crop all over the world. One of its most critical diseases that results in economic loss is ear rot caused by various Fusarium species. Previous researches have shown that polyamines, found in all living cells, play crucial role in biotic stress responses. At the same time, biosynthesis of polyamines is of paramount importance not only for plants but also for their pathogens to promote stress tolerance and pathogenicity. In our study, we investigated the polyamine content changes induced in the seedlings of two maize genotypes of different susceptibility by isolates of Fusarium verticillioides and Fusarium graminearum, two Fusarium species of different lifestyles. Apart from that, it was examined how infection efficiency and changes in polyamine contents were modified by salicylic acid or putrescine seed soaking pre-treatments. Our observations confirmed that initial and stress-induced changes in the polyamine contents are not directly related to tolerance in either coleoptile or radicle. However, the two pathogens with different lifestyles induced remarkably distinct changes in the polyamine contents. The effect of the seed soaking pre-treatments depended on the pathogens and plant resistance as well: both salicylic acid and putrescine seed soaking had positive results against F. verticillioides, while in the case of infection with F. graminearum, seed soaking with distilled water alone affected biomass parameters positively in the tolerant genotype.
Evolution of zinc coatings during drawing process of steel wires
Authors: Suliga Maciej , Wartacz Radosław , Hawryluk Marek 
Published: April 2023

Abstract
The paper shows a significant influence of the multi-stage wire drawing technology on deformability and phase transformations in the zinc coating. SEM tests proved that the coating after hot-dip galvanizing consists of a number of thin layers, ranging from 1 to 5 µm, and differing in thickness, chemical composition and properties. When pulled through the drawing die the zinc coating heats up (as a result of friction between the material and the tool) and its dynamic plastic deformation. It resulted in the fracture and partial crushing of the hard-intermetallic phases. It has been proven that as the wire passes through successive drawing dies, the coating is thinned and diffusion as well as phase remodelling of individual structural components occurs; in the place of phase ζ, the intermetallic phase δ1 develops, increasing its share in the diffusion layer. The crystals of intermetallic phases located on the border of the diffusion and outer layers break up and remain dispersed in the zinc. An analysis of the microhardness of the coating has proven that the level of the increase in the microhardness of the zinc coating is contingent on percentage of iron in particular layers of coating.
Intelligent Medicine on the Regulation Effect of Weekend Catch-Up Sleep on the Relationship Between Hypertension and All-Cause Mortality
Authors: Li Hui , Yang Min , Bao Yanchun 
Published: April 2023

AbstractThe current studies did not take into consideration the significant differences in sleep duration between weekdays and weekends, and the evidence on weekend catch-up sleep and the risk of cardiovascular/metabolic-related diseases was limited. This study was aimed to explore whether weekend catch-up sleep could modify the association between hypertension and all-cause mortality. This cohort study extracted the data of 5344 participants aged > 18 years in NHANES database. Demographic and clinical variables were included, and univariable and multivariable Proportional Hazards Model regression models were utilized to screen the potential confounding factors. The regulation role of mean weekend catch-up sleep on the association between hypertension and all-cause mortality was explored via the interactive product terms including mean weekend catch-up sleep, hypertension and mean weekend catch-up sleep × hypertension. In total, there were 3157 participants had hypertension. The mean follow-up time was 24.45 ± 1.51 months, and 5235 (98.57%) people were alive at the end of the follow-up. The mean weekend catch-up sleep was 0.71 h in alive people and 0.60 h in people with hypertension. After adjusting for age, gender, race, income, body mass index (BMI), depression, respiratory disease, and diabetes, hypertension was associated with an increased risk of all-cause mortality [hazard ratio (HR) = 2.17, 95% confidence interval (CI) 1.19–3.96]. The interaction between hypertension and mean weekend catch-up sleep was statistically significant in the adjusted model (P = 0.048). When we examined the HR for different mean weekend catch-up sleep groups, we observed that in people with mean weekend catch-up sleep ≤ 1 h, the HR of all-cause mortality associated with hypertension was 3.06 (95% CI 1.44–6.47) after adjusting for age, gender, race, income, BMI, depression, respiratory disease, and diabetes. Mean weekend catch-up sleep modified the association between hypertension and all-cause mortality, which suggested that weekend catch-up sleep might be important for people with hypertension. The findings might provide evidence in the management of sleep and hypertension for intelligent medical information system.
Student Anxiety and Its Impact: A Recent American History
Authors: Stearns Peter N. 
Published: April 2023

AbstractThis article traces the rise of anxiety among American high school and college students since the late 1950s, with particular focus on the decades before 2000. Evidence for rates of change comes from anxiety tests administered during the period, as well as a variety of psychological studies. The article also takes up the issue of causation, highlighting the extension of counseling services and psychological vocabulary that affected evaluations of nervousness; the impact of negative developments like crime rates and growing family instability; and the results both of changes in educational patterns—such as more frequent examinations—and significant shifts in student goals and expectations. Finally, the article touches on efforts to mitigate anxiety, such as expanding student services, and also their limited impact.
Soft Power, Modernization, and Security: US Educational Foreign Policy Toward Authoritarian Spain in the Cold War
Authors: Martín García Óscar José 
Published: April 2023

AbstractCold War strategic priorities led the United States to establish an enduring military alliance with General Francisco Franco's dictatorship in Spain between 1953 and 1975. This article examines the educational diplomacy carried out by the US government during the 1960s and early 1970s to foster Spain's stable modernization through the training of national development elites and the dissemination of US educational ideas. The work surveys US educational, informational, and cultural programs aimed at shaping an educational framework conducive to the expansion and legitimization of a US-oriented socioeconomic liberalization in Spain. On the one hand, this US soft power strategy sought to attract those groups who could play an important role in the capitalist modernization of the educational and economic structures of the Iberian country. On the other hand, it sought to reduce the identification of the United States with Franco's dictatorship and to link the image of the American superpower to the hopes for progress of the Spanish people. All of this was pursued in order to preserve US defensive interests in Spain. The piece also discusses US assistance to the crucial 1970 Spanish General Education Law, which allows us to explore how the US ideology of development and education was received by Spanish educational audiences. Thus, by delving deeper into the intersection between cultural diplomacy, international development, and the history of education, we aim to contribute to the integration of education into the histories of modernization and to deepen our understanding of US educational foreign policy in the Cold War.
Career calling climate: The development and validation of a scale for a new construct

Published: April 2023

Abstract
Having a sense of calling toward one's work has key benefits for both the employee and the employer. Yet, little is known about whether and what kind of work climate facilitates employees' senses of calling, hindering efforts toward positive changes from managers and organizations. This research introduces the concept of ‘career calling climate’ and describes the development of a scale (i.e., Career Calling Climate Scale) to measure the level of support that a work unit provides for its employees' pursuit of a calling. We established the scale's validity and reliability using survey responses from participants of various occupations and age. To provide evidence of its predictive validity, we examined career calling climate's relation with career callings using a sample of 189 healthcare employees nested in 34 work units. Results suggested that career calling climate predicted individuals' career callings. Implications for theory and practice are discussed.
Acculturation, Hispanic ethnicity, and trust: Verifying and explaining racial/ethnic differences in trust in health providers in North Carolina Medicaid
Authors: Smith Galen H. , Hampton Cicily , Tripp Hollie L. , Brandon William P. 
Published: April 2023

AbstractThree North Carolina Medicaid surveys conducted from 2000 to 2012 reported increasing numbers of Hispanic children enrolled in Medicaid and much lower trust in providers expressed by their adult caregiver respondents compared with responses for non-Hispanic Black and White children. To verify and explain this apparent trust chasm, we used bivariate and regression analyses. The variables employed included trust (dependent variable); child’s race/ethnicity, age, and sex; satisfaction and health status scales; two utilization measures; respondent’s age, sex, and education; geographical region; and population density of county of residence. Race/ethnicity was strongly associated with trust (p < .001), controlling for other independent variables. Access, satisfaction, and respondent’s age and education were also significant. Our results fit the Behavioral Model for Vulnerable Populations, which maps the role of significant variables in health-seeking behavior. After analyzing the concept of trust, we argue that lower acculturation explains lower Hispanic trust compared with non-Hispanic Blacks. We suggest policies to improve acculturation.
The new Cypriot music curriculum: teachers’ interpretation and implementation of differentiation
Authors: Hadjikou Chryso , Creech Andrea 
Published: April 2023

AbstractDifferentiation is a key concept in the Cypriot music curriculum, last revised in 2010. This paper aims to investigate teachers’ interpretation and implementation of differentiation in their music classrooms. Interviews with Cypriot classroom music teachers and focus groups with their students took place within the context of a larger research project that investigated how elements of the Cypriot music curriculum were interpreted and applied by teachers and how this pedagogy in turn influenced students’ motivation. Interviews were carried out with eight music teachers. Differentiation, as understood and implemented by these Cypriot music teachers, differed in fundamental ways to differentiation as conceptualised in academic literature concerned with this concept. These findings may serve as a point of reflection for future professional development in Cyprus relating to differentiation and its implementation.
The big picture: Reassessing population estimates and socio-spatial structure at the Zacapu Malpaís urban settlements using LiDAR
Authors: Forest Marion 
Published: April 2023

AbstractRecent research conducted in northern Michoacan, west Mexico, has yielded significant new datasets that can be used to reconsider the occupation of this region in the Postclassic period (a.d. 900–1541), prior to and during the rise of the Tarascan state. LiDAR data, in particular, has facilitated reassessment of the archaeological record and its implications concerning the population and social dynamics of this region. In this article, I combine data collected through traditional field-based research with LiDAR-derived data to reassess the population aggregation that occurred during a.d. 1250–1450 in the Zacapu Basin, resulting in the formation of a large urban system. Compared to prior population estimates and interpretations regarding the urban structure of the Zacapu Malpaís sites, the integration of these datasets enables both an increased scale of analysis and finer resolution, thus providing a clearer picture of one of the earliest episodes of urbanization in west Mexico.
Evolution of ancient farming systems and demography in the volcanic highlands of Zacapu: A model drawn from Geoarchaeology and archaeogeography
Authors: Dorison Antoine , Siebe Christina 
Published: April 2023

AbstractAmong the numerous archaeological remains that recent LiDAR flights revealed in Guatemala and Mexico, agrarian features are the most abundant. Archaeologists today are compelled to revise their paradigms in terms of methodology and assessment of environmental appropriation for agriculture. The Malpaís de Zacapu in west Mexico is one example. Besides the discovery of a substantial Epiclassic occupation near the well-documented Postclassic urban centers of the area, LiDAR imagery brought to light a deeply modified agrarian landscape and thereby dramatically changed our understanding of human settlement in this lava flows complex.Focusing on the northern part of the Malpaís, this study uses archaeogeographical and soil science methods to assess ancient farming systems and their evolution. We updated the archaeological and soil maps of the area, combining traditional field survey techniques and LiDAR-derived data interpretation. This allowed us to identify residential zones and a wide range of associated agrarian features adapted to the variety and agronomic challenges of volcanic soils. We further implemented a production-consumption model to reconstruct agricultural strategies from the Epiclassic to the Middle Postclassic period, from self-reliance to the necessity of supra-local agricultural inputs, possibly foreshadowing the Tarascan state tribute system.
