Provider responses to discontinuous tariffs: evidence from Dutch rehabilitation care
Authors: Gaspar Katalin , Koolman Xander 
Published: February 2022

AbstractAbrupt jumps in reimbursement tariffs have been shown to lead to unintended effects in physicians’ behavior. A sudden change in tariffs at a pre-defined point in the treatment can incentivize health care providers to prolong treatment to reach the higher tariff, and then to discharge patients once the higher tariff is reached. The Dutch reimbursement schedule in hospital rehabilitation care follows a two-threshold stepwise-function based on treatment duration. We investigated the prevalence of strategic discharges around the first threshold and assessed whether their share varies by provider type. Our findings suggest moderate response to incentives by traditional care providers (general and academic hospitals, rehabilitation centers and multicategorical providers), and strong response by profit-oriented independent treatment centers. When examining the variation in response based on the financial position of the organization, we found a higher probability of manipulation among providers in financial distress. Our findings provide multiple insights and possible indicators to identify provider types that may be more prone to strategic behavior.

Published: February 2022

AbstractMourning constitutes an important human emotion, which might cause—among other things—major depressive symptoms when lasting for too long. To date, no study investigated whether mourning is related to specific psychophysiological activation patterns. Therefore, we examined physiological reactions induced by iconographic mourning-related stimuli in comparison to neutral and attachment stimuli in healthy adults (N = 77, mean age: 21.9). We evaluated pupillometric and eye-tracking parameters as well as heart rate variability (HRV) and skin conductance (EDA). Eye-tracking revealed a stronger dilated pupil during mourning in comparison to the neutral, but not to the attachment condition; furthermore, fixation patterns revealed less fixations on mourning stimuli. While HF HRV was reduced during mourning and attachment, we found no differences concerning EDA parameters between conditions. Results suggest specific eye-movement and pupil adaptations during representations of mourning, which might point toward inward cognition or avoidance, but no specific physiological pattern concerning HRV and EDA.

Abstract
Purpose
Measuring health-related quality of life (HRQoL) with the EQ-5D-5L might lack sensitivity for disease-specific health complaints. This cross-sectional study analyzed whether fatigue and cognitive problems are captured by the EQ-5D-5L in a Q-fever patient population with persistent fatigue/cognitive problems, and whether addition of fatigue/cognition improved the explained variance for HRQoL.

Methods
A Dutch sample of Q-fever patients filled out the EQ-5D-5L and EQ VAS, the fatigue subscale of the Checklist Individual Strength, and a cognition dimension in the EQ-5D-5L format. The extent to which fatigue and cognition were captured by the EQ-5D-5L was determined based on distributional effects, head-to-head comparisons, Spearman rank correlation coefficients, and regression analyses. Explanatory power was determined of the EQ-5D-5L for the EQ VAS with and without a fatigue and cognition dimension.

Results
Out of 432 respondents, 373(86%) reported severe fatigue, 387(90%) cognitive problems. EQ-5D-5L utility and EQ VAS scores of respondents reporting severe fatigue/cognitive problems were significantly lower. Fatigue was strongly correlated with EQ-5D-5L dimensions usual activities and pain/discomfort (r = 0.602 and r = 0.510) and moderately with other EQ-5D-5L dimensions (r = 0.305–0.476). Cognition was strongly correlated with usual activities (r = 0.554) and moderately with other dimensions (r = 0.291–0.451). Adding fatigue to the EQ-5D-5L increased explanatory power for the EQ VAS with 6%.

Conclusion
Fatigue and cognitive problems in Q-fever patients were partially captured by the EQ-5D-5L dimensions. The addition of fatigue to the EQ-5D-5L slightly improved explained variance for the EQ VAS. This potentially also accounts for patients who experience sequelae of other infectious diseases, such as COVID-19.
Factors affecting the learning curve in robotic colorectal surgery
Authors: Wong Shing Wai , Crowe Philip 
Published: February 2022

AbstractLearning related to robotic colorectal surgery can be measured by surgical process (such as time or adequacy of resection) or patient outcome (such as morbidity or quality of life). Time based metrics are the most commonly used variables to assess the learning curve because of ease of analysis. With analysis of the learning curve, there are factors which need to be considered because they may have a direct impact on operative times or may be surrogate markers of clinical effectiveness (unrelated to times). Variables which may impact on operation time include surgery case mix, hybrid technique, laparoscopic and open colorectal surgery experience, robotic surgical simulator training, technology, operating room team, and case complexity. Multidimensional analysis can address multiple indicators of surgical performance and include variables such as conversion rate, complications, oncological outcome and functional outcome. Analysis of patient outcome and/or global assessment of robotic skills may be the most reliable methods to assess the learning curve.
Geoheritage in the Minett UNESCO Biosphere (Southern Luxembourg): Inventory, Evaluation, and Conservation Aspects of Representative Geosites
Authors: Weis Robert 
Published: February 2022

AbstractThe southwestern part of Luxembourg, known as Minett in the local language use, exposes an exceptionally high diversity of marine near-shore sediment rocks from the Early to Middle Jurassic, owing to its proximal position at the north-eastern margins of the Paris Basin. The iconic Minette ironstone formation is known as the worldwide largest oolitic ironstone deposit from the last 500 my and the abandoned open cast mines are nowadays protected sites with a high biodiversity, intrinsically linked to geodiversity. The schistes bitumineux unit, a lateral equivalent of the well-known Posidonienschiefer of the Holzmaden region (South Germany), is frequently studied for its exceptionally preserved fossils of marine vertebrates, cephalopods, and insect remains, deserving its status as a Fossil-Lagerstätte of international relevance. Of regional importance are the Rumelange limestones, with coral patch-reef paleo-environments. The geomorphological main feature of the region is the Cuesta of the Middle Jurassic (‘Dogger-Schichtstufe’), with several outliers (‘Zeugenberge’) that represent widely visible landmarks in the landscape. In this paper, 16 geosites, representative of the geological, palaeontological, geomorphological, and hydrogeological heritage in the Minett UNESCO biosphere, are presented and evaluated according to scientific, educational, and geotouristic criteria.

AbstractKabocha squash, Cucurbita maxima Duchesne, in delayed-start culture is one of the major cultivation systems in southwestern Japan. Honeybee introduction or hand-pollination has been practiced in this crop system, but the species composition, abundance, and pollination efficiency of major pollinators remain unclear. In the current study, we investigated which insect(s) accomplish pollination of kabocha squash. Among the total visitations to female flowers, honeybees, mostly Apis mellifera L. (Hymenoptera: Apidae), dominated at 94.4% and 85.3% at the experimental field in 2019 and 2020, respectively, followed by the bumblebee Bombus diversus diversus Smith (Hymenoptera: Apidae) and the hummingbird hawkmoth Macroglossum pyrrhosticta Butler (Lepidoptera: Sphingidae). The number of pollen grains on the body surface of B. diversus diversus individuals was significantly greater than that on honeybees, such that a single visit by B. diversus diversus deposited 5–6 times more pollen grains on a stigma than a honeybee visit, meaning that the bumblebee is a more efficient pollinator at the individual level. However, visitations by numerous honeybees compensated for their lower individual efficiency and resulted in fruit set. In addition, we report for the first time that a lepidopteran can pollinate squash: our data indicate that pollen grains deposited by several visits of M. pyrrhosticta were likely to exceed the estimated minimum number of pollen grains required for fruit set. Our survey at the experimental field and at three private farms revealed that far more pollen than is required for fruit set was deposited on the stigmas by wild pollinators and wintering honeybees. These findings indicate that kabocha squash production in delayed-start culture in this region is practicable without pollination enhancement effort, such as honeybee introduction or hand-pollination.
Understanding postgraduate students’ perceptions of plagiarism: a case study of Vietnamese and local students in New Zealand
Authors: Tran Minh Ngoc , Hogg Linda , Marshall Stephen 
Published: February 2022

AbstractDespite increasing scholarly interest in tertiary student perceptions of plagiarism, very little is known about those held by postgraduate (PG) students, although differences between undergraduate (UG) and PG students relate to both their characteristics and the demands of their studies. Furthermore, there is a dearth of research within the context of international education, where managing plagiarism is seen as a major challenge. This paper reports on a recent online survey with 207 Vietnamese (n = 72) and local (n = 135) PG students at a New Zealand university regarding their perceptions of plagiarism. The findings showed significant differences both between and within the two groups. Perception variations arose from a range of influences and prior experiences, not just the culture in which the students were initially educated. Differences related to participants’ age, gender, academic levels, disciplines, and teaching experience. This study’s findings contribute knowledge about under-researched PG students and problematize prevalent stereotypes of international students regarding plagiarism. They generate implications for higher education institutions to accommodate international and domestic PG student needs in ways that respect their diversities in detail as individuals, not as members of a homogeneous group. Further qualitative research to explore PG student perceptions in greater depth is recommended.
Sources of variability in the acquisition of Differential Object Marking by Turkish heritage language children in the United States
Authors: Coskun Kunduz Aylin , Montrul Silvina 
Published: February 2022

AbstractDifferential object marking (DOM) is an area of vulnerability in adult heritage speakers. This study traces such vulnerability to childhood by examining Turkish DOM in child Turkish heritage speakers in the U.S and the parental generation, who are the main input providers. Twenty first-generation immigrants, 20 adult and 20 child (aged 7–14) Turkish heritage speakers, and the monolingual group including 20 Turkish-speaking adults, 20 7–14-year-old and 20 3–6-year-old Turkish-speaking children in Turkey completed a story retelling task and a picture selection task. Results showed that the first-generation immigrants patterned with the monolingual adults. However, the heritage speakers (children and adults) omitted DOM in both tasks, showing more variable performance than the monolingual groups. These findings suggest that instability of DOM in heritage grammars is more likely due to insufficient input in the early years of heritage language development than to changes in parental input or attrition in later years.

Published: February 2022

Was ist bereits zu diesem Thema bekannt? Der Einsatz von EX-IN-Genesungsbegleiter_innen (GB) in der Psychiatrie erfolgt zwar schon seit einigen Jahren, ist aber noch längst nicht flächendeckend eingeführt. Wie wird eine neue Perspektive eingebracht? Durch eine Befragung von Pflegeteams der LWL-Klinik Dortmund bei denen GB zum Einsatz kommen, werden Erfahrungen und Erkenntnisse der Pflegefachpersonen in der Zusammenarbeit zusammengefasst. Was sind die Auswirkungen für die Praxis? Gelingt die Integration von GB in die Behandlungsteams profitiert man durch die Ausweitung der Angebote, welche durch herkömmliche Fachpersonen nicht übernommen werden kann. GB können zu einer Haltungsänderung bei Pflegefachpersonen im Umgang mit Patient_innen beitragen, die von der professionellen Distanz hin zur professionellen Nähe führt.

Published: February 2022

Abstract: Research in psychology and social neuroscience distinguishes between dispositional and situational empathy for the cognitive and affective aspects of empathy. Yet, the Pictorial Empathy Test (PET) is one of the few brief tests focusing on situational affective empathy. This paper describes the adaptation of PET in a two-stage process, consisting of instrument translation and exploratory analysis of the construct in a university student sample, followed by confirmatory factor analysis and psychometric validation in a general population sample (Study 1, N = 79 and Study 2, N = 580). Our results indicate that the Spanish PET version constitutes a single factor structure with high internal consistency as well as high construct stability across genders and across in-person and online test administration setups. We report satisfactory convergent, discriminant, and nomological validity of the Spanish PET, as reported for the original version, in addition to when explored across new dimensions, like the Interpersonal Reactivity Index or in relation to age and prosocial tendencies. Based on the above, we discuss delineation of the distinct components of emotional empathy as measured by the instrument. The work presented supports the use of the Spanish PET version as a brief screening tool for state affective (emotional) empathy.

Abstract. Background: Coping is considered to have an important influence on well-being, especially in adolescent refugees dealing with a high amount of stress. In addition, gender differences in coping are a common topic for research and are often attributed to differences in socialization between boys and girls. Aims: The study aims at clarifying the gender differences in coping strategies used by non-Western adolescents. Additionally, associations with aspects of socialization, in particular Gender Role Attitudes (GRA), on gender differences are investigated. Method: Refugees from Syria, Iraq, and Afghanistan ( N = 106, 55% male) aged 11–18 years completed questionnaires in schools or housing facilities. Associations between gender, GRA, coping strategies, and well-being were investigated using moderation and regression analyses. Results: Gender differences found in previous literature could, in part be replicated. Refugee girls reported more anger-related emotion regulation than boys did. However, GRA did not show any connections to coping strategies. Limitations: Most limitations result from low reliabilities and possible biases due to the use of self-reports. Conclusion: The more frequent use of anger-related emotion regulation as the only gender difference replicated in this study highlights the importance of research with refugee samples to prevent over-generalization of previous results from Western cultures.
Scaling Behavior of Thermally Driven Fractures in Deep Low‐Permeability Formations: A Plane Strain Model With 1‐D Heat Conduction
Authors: Chen Bin , Zhou Quanlin 
Published: February 2022

AbstractInjection of cold fluids through/into deep formations may cause significant cooling, thermal stress, and possible thermal fracturing. In this study, the thermal fracturing of low‐permeability formations under one‐dimensional heat conduction was investigated using a plane strain model. Dimensionless governing equations, with dimensionless fracture length , aperture , spacing , time , and effective confining stress , were derived. Solution of single thermal fracture was derived analytically, while solution of multiple fractures with constant (or dynamic) spacing were obtained using the displacement discontinuity method (and stability analysis). For single fracture, increases nonlinearly with and then transitions to scaling law , indicating that late‐time fracture length increases linearly with the square root of cooling time. For constantly spaced fractures, deviates from the single‐fracture solution at a later for a larger , showing slower propagation under inter‐fracture stress interaction. For dynamically spaced fractures, fracture arrest induced by stress interaction was determined by the stability analysis; the fully transient solution provides evolution of dimensionless fracture length, spacing, aperture, and pattern; a similar scaling law, with , obtained shows the effect of both stress interaction and fracture arrest. The solution and scaling law provide fast predictions for all reservoir and cooling conditions using (single) model parameter . Application to a geothermal site with demonstrates that thermal fractures reach 0.67, 6.25, and 78.00 m in length, 0.49, 2.30, and 13.00 m in spacing, and 0.43, 2.09, and 12.19 mm in aperture at 1, 100, and 10,000 days.

AbstractPlant canopy temperature (Tc) is partly regulated by evaporation and transpiration from the canopy surface and can be used to infer changes in stomatal regulation and vegetation water stress. In this study, we used a thermal Unmanned Aircraft Systems in conjunction with eddy covariance, sap flow, and spectral reflectance data to assess the diurnal characteristics of Tc and water stress status over a semiarid mixed conifer forest in Arizona, USA. Diurnal Tc dynamics were closely related to tree sap flow and changes in spectral reflectance associated with stomatal regulation. Consistent with previously reported deviations, we found that on average Tc was 1.8°C lower than the above canopy air temperature (Ta). However, the relationship between Tc and Ta varied significantly according to tree density and tree height classes, with taller and denser trees exhibiting relatively low |Tc‐Ta| (2.4 and 2.1°C cooler canopies, respectively) compared to shorter and less‐dense tree stands (1.7 and 1.5°C cooler canopies, respectively). We used these data to evaluate space‐borne diurnal measurements of Tc and water stress from the ECOsystem Spaceborne Thermal Radiometer Experiment on Space Station (ECOSTRESS) mission. We found that ECOSTRESS observations of Tc accurately tracked seasonal shifts in diurnal surface temperatures and vegetation water stress, and that site‐level observations of heterogeneity in forest composition and structure could be applied to separate the processes of canopy transpiration and soil evaporation within the ECOSTRESS footprint. This study demonstrates how proximal and satellite remote sensing approaches can be combined to reveal the diurnal and seasonally dynamic nature of Tc and water stress.

AbstractEpstein–Barr virus (EBV) was the first oncogenic virus identified in humans. It is primarily associated with multiple lymphoid and epithelial cancers, including nasopharyngeal carcinoma (NPC). However, its association with ferroptosis and its role in cancer therapy resistance have not been fully elucidated. Here, we show that EBV infection reduces the sensitivity of NPC cells to ferroptosis by activating the p62-Keap1-NRF2 signaling pathway in conjunction with upregulation of SLC7A11 and GPX4 expression. Knockdown of endogenous GPX4 or blockade of GPX4 using a specific inhibitor enhanced the chemosensitivity of EBV-infected NPC cells. Functional studies revealed that GPX4 knockdown suppresses the proliferation and colony formation of NPC cells. Mechanistically, GPX4 interacts with the TAK1-TAB1/TAB3 complex, regulates TAK1 kinase activity, and further activates downstream MAPK-JNK and NFκB pathways. High GPX4 expression is correlated with poor clinical outcomes in patients with NPC and other cancer types. Taken together, our findings suggest that EBV infection has important effects on redox homeostasis, revealing a previously unappreciated role for GPX4 in tumor progression. This novel mechanism provides a potential new target for the treatment of EBV-related tumors.
