Published: July 2021

Background

Assessment of MCT laxity is critical to the surgery options. Our study aimed to analyze the reliability of measuring medial canthal tendon (MCT) laxity by using a novel standardized three-dimensional lateral distraction test (3D-LDT).

Methods

Forty-eight Caucasian volunteers (25 males and 23 females, 96 eyes) between 22 and 84 years of age (55.6 ± 18.6 years old) were included in our study. From a neutral position, the lower eyelid was gently pulled laterally along a horizontal line to define the most distracted position of the lower punctum. Both in the neutral and distracted position, standardized 3D images were acquired for each subject by two observers, and each image were measured twice by two raters. Four landmarks and six corresponding linear measurements were evaluated for intra-rater, inter-rater, and inter-method reliability.

Results

Intra-rater, inter-rater and inter-method reliability analyses of 3D-LDT revealed an intraclass correlation of more than 95%, a mean absolute difference of less than 1 mm, and a technical error of measurement of less than 1 mm. Measurements of relative error (2.59–12.04%) and relative technical error (1.83–16.05%) for the inter-landmarks distance from pupil center to the lower punctum were higher than those from limbus nasal center to the lower punctum (6.13–30.39 and 4.34–26.85%, respectively).

Conclusions

This study provided high reliability of the three-dimensional lateral distraction test (3D-LDT) for assessing medial canthal tendon (MCT) laxity, which were never evaluated by digital imaging system.

Outcome-Based Assessment of the Payment for Mountain Agriculture: A Community-Based Approach to Countering Land Abandonment in Japan
Authors: Shoyama Kikuko , Nishi Maiko , Hashimoto Shizuka , Saito Osamu
Published: July 2021

Agricultural land accounts for 37% of the world’s terrestrial area, and the multiple functions of agroecosystems—providing food, soil and water retention, and various cultural services—are of great importance for sustainable land management. To ensure that multifunctionality, payment for ecosystem services (PES) schemes have been developed for heterogeneous agroecosystems. However, the effects of the schemes have not been fully measured because, in most cases, they have been implemented as action-oriented programs rather than outcome-based payments. This study examines the effect of a community-based PES (CB-PES) program on the prevention of farmland abandonment to assess the agricultural outcomes of PES implementation in hilly and mountainous areas in Japan. We interviewed farmers in enrolled communities, mapped enrolled plots, and analyzed agricultural census data on the socioeconomic characteristics and farmland management conditions of 12,261 farmers in 960 agricultural communities in a typical hilly and mountainous area of Noto Peninsula in northern Japan. The results confirm that direct payments are effective in enhancing community management and in preventing additional farmland abandonment. In addition, we found that several socioeconomic and environmental factors at both the community and farmer levels—including geographical conditions, collective management activities, absence of successors, farm scale, and off-farm income dependency—simultaneously affected the farmland abandonment process. Specifically, collective practices within and between communities is a significant factor in preventing farmland abandonment more than collaboration with outsiders. Considering the depopulation and aging of rural communities throughout Japan, intercommunity enrollment could improve the effectiveness of CB-PES by upscaling the current payment scheme to maintain community functions.

Published: July 2021

Background

RCS Eng, the Royal College of Surgeons of England, has published much information with regard to the consenting process. A majority of patients seek health information through online resources as well as discussing with the care givers. Therefore, it is necessary that online material is both of high quality and reliable for patients. We aimed to evaluate the quality and standard of the online patient information on laparoscopic cholecystectomy to help in the consenting process.

Methods

A search was carried out as per the Preferred Reporting Items for Systematic Reviews and Meta‐Analyses (PRISMA) guidelines. Sources were assessed using five validated scoring tools: Flesch–Kincaid Reading Ease Score (readability), DISCERN and IPDAS scores (quality of content) and HONcode and the Information Standard Certification (standards of accreditation).

Results

The average readability of all websites was higher than recommended for patient literature. Less than half of the sources had received HONcode or Information Standard accreditation. On grading of quality and content, across validated scoring tools, no source achieved the minimum recommended level.

Conclusion

Online patient information related to laparoscopic cholecystectomy is of poor quality. We recommend a multidisciplinary approach to participate in publishing more readable online resources of a higher standard to help patients and clinicians in consent and shared decision making.

Published: July 2021

Background

The diagnosis of sarcopenia emphasizes both, the quantity and quality of skeletal muscle. However, the impact of the combination of muscle quantity and quality on long‐term survival remains unclear. This study aimed to assess the impact of the combination of skeletal muscle quantity and quality on long‐term outcomes in patients with gastric cancer who underwent curative resection.

Methods

We retrospectively assessed 242 patients aged ≥ 65 ears who underwent curative gastrectomy between 2006 and 2015. The psoas muscle mass index (PMI) and intramuscular adipose tissue content (IMAC) were measured on preoperative computed tomography as skeletal muscle quantity and quality, respectively. The sarcopenia stage was classified by the combination of preoperative skeletal muscle quantity and quality (non‐sarcopenia, sarcopenia, and severe sarcopenia). Prognostic factors for the 5‐year overall survival (OS), non‐cancer‐specific survival (non‐CSS), and cancer‐specific survival (CSS) were evaluated by multivariable Cox regression.

Results

The median follow‐up period was 63.2 months. The non‐sarcopenia, sarcopenia, and severe sarcopenia groups comprised 88, 121, and 33 patients (36.4%, 50.0%, and 13.6%), respectively. The severe sarcopenia group was older, and had a greater depth of invasion, than the non‐sarcopenia group. Multivariable analysis revealed severe sarcopenia as an independent predictive indicator of OS (hazard ratio [HR] 4.01; 95% confidence interval [CI] 1.75 to 9.22) and non‐CSS (HR 3.27; 95% CI 1.61 to 6.67), but not CSS.

Conclusions

The combination of preoperative skeletal muscle quantity and quality was useful for predicting survival, especially death from other diseases, in elderly patients who underwent gastrectomy for gastric cancer.

Authors: Stolz Jonathan , Oguzlu Hale , Khalili Zahra , Boluk Yaman
Published: July 2021

We investigated the gelation and microstructure of cellulose nanocrystals (CNCs) in nonionic hydroxyethyl cellulose (HEC) solutions. Cellulose nanocrystals (CNCs) with a particle length of 90 nm and width of 8 nm currently produced by acid hydrolysis of wood pulp were used in this study. The microstructures of CNCs/polymer suspensions were investigated by performing linear small amplitude oscillatory shear (SAOS) and nonlinear large amplitude oscillatory shear (LAOS), in addition to constructing CNCs phase diagrams and measuring steady-state shear viscosities. Significant viscosity increases at low shear rates coupled with high shear thinning behaviors were observed in CNCs in HEC solutions above the overlapping concentration of HEC. The physical strength of CNCs/HEC solution gels increased with the increase in CNCs concentration and resembled the weakly crosslinked gels according to the scaling of linear dynamic mechanical experiments. According to LAOS analysis, CNCs/HEC mixtures showed type III behavior with intercycle stress softening, while the samples showed stress stiffening in single cycles.

Kabuki syndrome (KS) is a well-recognized disorder characterized by postnatal growth deficiency, dysmorphic facial features, skeletal anomalies, and intellectual disability. The syndrome is caused by KMT2D gene mutations or less frequently KDM6A gene mutations or deletions. We report a systematic evaluation of KS patients from Campania region of Italy; data were also compared with literature ones. We collected data of 15 subjects (8 males and 7 females with age range 10–26 years; mean age 16.9 years) with confirmed diagnosis of KS, representing the entire cohort of patients from Campania Region. Each patient performed biochemical testing and instrumental investigation. Neuro-intellectual development, cranio-facial dysmorphisms, and multisystem involvement data were collected retrospectively. For each category, type of defects and frequency of the anomalies were analyzed. Our observation shows that KS patients from Campania region have some particular and previously underscored, neurological and immunological findings. We found high prevalence of EEG’s abnormalities (43%) and MRI brain abnormalities (60%). Microcephaly resulted more common in our series (33%), if compared with major cohorts described in literature. Biochemical features of immunodeficiency and autoimmune diseases including thyroid autoimmunity, polyserositis, and vitiligo were observed with high prevalence (54.5%). Low immunoglobulins levels were a frequent finding. Lymphocyte class investigation showed significantly reduced CD8 levels in one patient.

Conclusions: These data confirm great heterogeneity of clinical manifestations in KS and suggest to introduce further clinical diagnostic criteria in order to perform a correct and precocious diagnosis.

What is Known• Kabuki syndrome is characterized by growth deficiency, dysmorphic facial features, skeletal anomalies, and intellectual disability• Immune dysfunction is a common finding but autoimmune diseases are rarely seen• Neurological features are common

What is New• Some particular facial features could help gestalt diagnosis (hypertelorism, broad nasal bridge, micrognathia, tooth agenesis, cutaneous haemangiomas and strabismus)• Higher prevalence of autoimmune disorders than previously reported• Particular neurological features are present in this cohort (EEG and MRI brain abnormalities)
Exploring the relationship among dispositional optimism, health-related quality of life, and CIPN severity among colorectal cancer patients with chronic peripheral neuropathy
Authors: Trompetter Hester.R. , Bonhof Cynthia S. , van de Poll-Franse Lonneke V. , Vreugdenhil Gerard , Mols Floortje
Published: July 2021

Purpose

Chemotherapy-induced peripheral neuropathy ((CI)PN) becomes chronic in 30% of cancer patients. Knowledge of predictors of chronic (CI)PN and related impairments in health-related quality of life (HRQoL) is lacking. We examined the role of optimism in chronic (CI)PN severity and associated HRQoL in colorectal cancer (CRC) patients up to two years after diagnosis.

Methods

CRC patients from a prospective cohort study participated, with sensory peripheral neuropathy (SPN) 1 year after diagnosis (n = 142). Multivariable regression analyses examined the cross-sectional association between optimism (measured by the LOT-R) and SPN severity/HRQoL (measured by the EORTC QLQ-CIPN20 and QLQ-C30), as well as the prospective association in a subsample that completed measures 2 years after diagnosis and still experienced SPN (n = 86).

Results

At 1-year follow-up, higher optimism was associated with better global HRQoL, and better physical, role, emotional, cognitive, and social functioning (all p < .01). Optimism at year one was also prospectively associated with better global HRQoL (p < .05), and emotional and cognitive functioning at 2-year follow-up (both p < .01). Optimism was not related to self-reported SPN severity. Significant associations were retained when controlling for demographic/clinical variables, and became non-significant after controlling for depressive and anxiety symptoms.

Conclusions

Optimism and depressive and anxiety symptoms are associated with HRQoL in CRC patients with chronic (CI)PN. Future research may illuminate the mechanisms that these factors share, like the use of (non)adaptive coping styles such as avoidance and acceptance that may inform the design of targeted interventions to help patients to adapt to chronic (CI)PN.
Corona discharge of a vibrated insulating box with granular medium
Authors: Schoenau Laurent , Steinpilz Tobias , Teiser Jens , Wurm Gerhard
Published: July 2021

Corona discharges are luminous signs of strong local electric fields allowing a continuous discharge into the surrounding atmosphere. They commonly occur at the ends of conductors at high voltage. Here we report the observation of a faint glow surrounding an insulating cm-sized box filled with mm-sized basalt beads. At an ambient pressure in the mbar range two light bands occur as soon as and only if the box is vibrated and only if it is filled with a granular medium. In addition, a glow also occurs at the inside of the box. We measured periodic electric fields at the outside of the box with spatial peaks at the positions of the light bands. The period correlates to the vibration frequency. These observations imply strong alternating fields beyond atmospheric breakdown, which are generated inside and also emerge at the outside of the insulating box. The observations can be explained by tribocharging and periodic displacement of charges between grains and the inside walls of the box.
Systemic risk measurement: bucketing global systemically important banks
Authors: Brogi Marina , Lagasio Valentina , Riccetti Luca
Published: July 2021

The general consensus on the need to enhance the resilience of the financial system has led to the imposition of higher capital requirements for certain institutions, supposedly based on their contribution to systemic risk. Global Systemically Important Banks (G-SIBs) are divided into buckets based on their required additional capital buffers ranging from 1% to 3.5%. We measure the marginal contribution to systemic risk of 26 G-SIBs using the Distressed Insurance Premium methodology proposed by Huang et al. (J Bank Financ 33:2036–2049, 2009) and examine ranking consistency with that using the SRISK of Acharya et al. (Am Econ Rev 102:59–64, 2012). We then compare the bucketing using the two academic approaches and supervisory buckets. Because it leads to capital surcharges, bucketing should be consistent, irrespective of methodology. Instead, discrepancies in the allocation between buckets emerge and this suggests the complementary use of other methodologies.
Deep reinforcement learning methods for structure-guided processing path optimization
Authors: Dornheim Johannes , Morand Lukas , Zeitvogel Samuel , Iraki Tarek , Link Norbert , Helm Dirk
Published: July 2021

A major goal of materials design is to find material structures with desired properties and in a second step to find a processing path to reach one of these structures. In this paper, we propose and investigate a deep reinforcement learning approach for the optimization of processing paths. The goal is to find optimal processing paths in the material structure space that lead to target-structures, which have been identified beforehand to result in desired material properties. There exists a target set containing one or multiple different structures, bearing the desired properties. Our proposed methods can find an optimal path from a start structure to a single target structure, or optimize the processing paths to one of the equivalent target-structures in the set. In the latter case, the algorithm learns during processing to simultaneously identify the best reachable target structure and the optimal path to it. The proposed methods belong to the family of model-free deep reinforcement learning algorithms. They are guided by structure representations as features of the process state and by a reward signal, which is formulated based on a distance function in the structure space. Model-free reinforcement learning algorithms learn through trial and error while interacting with the process. Thereby, they are not restricted to information from a priori sampled processing data and are able to adapt to the specific process. The optimization itself is model-free and does not require any prior knowledge about the process itself. We instantiate and evaluate the proposed methods by optimizing paths of a generic metal forming process. We show the ability of both methods to find processing paths leading close to target structures and the ability of the extended method to identify target-structures that can be reached effectively and efficiently and to focus on these targets for sample efficient processing path optimization.
Deposition of dust with active substances in pesticides from treated seeds in adjacent fields during drilling: disentangling the effects of various factors using an 8-year field experiment

Published: July 2021

The side effects from the use of plant protection products and their potential effects on non-target arthropods (NTAs) such as honey bees, other insects within the vegetation layer and epigeic arthropods nowadays receive more attention. However, uncertainties about the factors driving the deposition of active substances (a.s.) into off-crop areas persist, in particular during sowing of treated seeds. Analysing a highly standardised 8-year field experiment, we assessed the importance of various factors potentially affecting dust drift and deposition of a.s., emitted during the sowing process of treated seeds and deposited on fields adjacent to the drilling field, i.e. on the ground, on flowers, and on nonflowering plant parts. Regarding a.s. deposition, the Heubach a.s. value has a predictive capability, which is independent from all other factors taken into account in this study, and can thus be considered as a scenario-independent measure of potential dust deposition. Petri dish samplers, an established standard method for measuring a.s. deposition, were representative of the results from the plant samplers for a given combination of drilling technique and adjacent crop type. Adjacent crop type is likely to impact on a.s. deposition. The present work will enable a more field-realistic exposure assessment for bees and other NTAs.
Von Performativität zu Generativität: Bewertung und ihre Folgen im Kontext der Digitalisierung
Authors: Mennicken Andrea , Kornberger Martin
Published: July 2021

In diesem Beitrag gehen wir zwei Fragen nach. Erstens, inwiefern kann ein Fokus auf Praktiken der Bewertung zur Klärung des Zusammenhangs zwischen Vergleich, Kategorisierung und Quantifizierung beitragen? Und zweitens, inwieweit verhilft er dazu, die Voraussetzungen und Folgen neuer digitaler Formate, wie etwa Vergleichsportale, Empfehlungssysteme oder Screening- und Scoring-Verfahren, besser zu verstehen? Im Gegensatz zur Auffassung, dass Wert im Bewusstsein des Subjekts (als Präferenz) existiert oder eine objektive Eigenschaft eines Gutes ist, argumentieren wir, dass ein Gut erst durch Bewertungspraktiken und -technologien wie Ratings, Rankings und andere evaluative Infrastrukturen als wertvoll oder als nicht wertvoll bestimmt wird. Wir entwickeln einen analytischen Rahmen für die Untersuchung interaktiver, digitalisierter Bewertungstechnologien und schlagen vor, dass sich solche Technologien besser analysieren und verstehen lassen, wenn wir den Fokus auf drei Elemente legen: erstens auf evaluative Infrastrukturen, verstanden als Bewertungsregime – und nicht als einzelne Bewertungsinstrumente, zweitens auf dasProtokollals ein evaluativen Infrastrukturen eigenes Machtinstrument, wobei Macht in diesem Fall paradoxerweise (und im Unterschied zum Disziplinarregime) zugleich verteilt und konzentriert ist, und drittens auf dasgenerative(statt nur performative) Potenzial solcher digitalisierter Bewertungsregime, also deren Fähigkeit, neue Werte und Kategorisierungen mittels evaluativer Infrastrukturen zu produzieren.
Learning from knowledge co-production research and practice in the twenty-first century: global lessons and what they mean for collaborative research in Nunatsiavut

An increasing need for novel approaches to knowledge co-production that effectively and equitably address sustainability challenges has arisen in the twenty-first century. Calls for more representative and contextual co-production strategies have come from Indigenous communities, scientific research forums, and global environmental governance networks. Despite calls to action, there are no systematic reviews that derive lessons from knowledge co-production scholarship to interpret their significance through the lens of a specific sociopolitical and cultural context. We conducted a systematic review of peer-reviewed and grey literature on knowledge co-production published from 2000 to 2020. Using a hybrid inductive and deductive thematic analysis, we identified two conceptual themes—guiding principles and approaches—to structure the synthesis and interpretation of 102 studies. We found that knowledge co-production studies often converged on four interrelated principles: recognition of contextual diversity bounding knowledge co-production, preemptive and intentional engagement with Indigenous knowledge holders, formation of shared understanding of the purpose of knowledge co-production, and empowerment of knowledge holders throughout the co-production cycle. These principles manifested in multiple approaches for interpreting, bridging, applying, and distributing power amongst diverse knowledge systems rooted in different epistemologies. We filter these findings through the social–ecological context that frames an ongoing knowledge co-production project with Inuit communities in Nunatsiavut, Canada: theSustainable Nunatsiavut Futures Project. Our review suggests that emerging forms of knowledge co-production principles and approaches yield immense potential in diverse contexts. Yet in many regions, including Nunatsiavut, principles alone may not be enough to account for systemic and contextualized issues (e.g., colonisation and data sovereignty) that can present roadblocks to equitable sustainability science in the twenty-first century if left unaddressed.
Development of Low-Yield Stress Co–Cr–W–Ni Alloy by Adding 6 Mass Pct Mn for Balloon-Expandable Stents
Authors: Yanagihara Soh , Ueki Kosuke , Ueda Kyosuke , Nakai Masaaki , Nakano Takayoshi , Narushima Takayuki
Published: July 2021

This is the first report presenting the development of a Co–Cr–W–Ni–Mn alloy by adding 6 mass pct Mn to ASTM F90 Co–20Cr–15W–10Ni (CCWN, mass pct) alloy for use as balloon-expandable stents with an excellent balance of mechanical properties and corrosion resistance. The effects of Mn addition on the microstructures as well as the mechanical and corrosion properties were investigated after hot forging, solution treatment, swaging, and static recrystallization. The Mn-added alloy with a grain size of ~ 20 µm (recrystallization condition: 1523 K, 150 seconds) exhibited an ultimate tensile strength of 1131 MPa, 0.2 pct proof stress of 535 MPa, and plastic elongation of 66 pct. Additionally, it exhibited higher ductility and lower yield stress while maintaining high strength compared to the ASTM F90 CCWN alloy. The formation of intersecting stacking faults was suppressed by increasing the stacking fault energy (SFE) with Mn addition, resulting in a lower yield stress. The low-yield stress is effective in suppressing stent recoil. In addition, strain-induced martensitic transformation during plastic deformation was suppressed by increasing the SFE, thereby improving the ductility. The Mn-added alloys also exhibited good corrosion resistance, similar to the ASTM F90 CCWN alloy. Mn-added Co–Cr–W–Ni alloys are suitable for use as balloon-expandable stents.
Diachronic Tendency and Thinking Style Across the Broader Autism Spectrum: Sources of Individual Differences?
Authors: Orm Stian , Holmberg Ella Holt , Harris Paul L. , Nunez Maria , Pons Francisco
Published: July 2021

Objectives

First, to see whether previous studies showing a limited capacity to spontaneously evoke the past and the future of a present moment (diachronic tendency) and a prevalence of mental images over inner speech (thinking style) in individuals with autism spectrum disorder could be replicated in individuals belonging to the broader autism phenotype. Second, to test the hypothesis that individuals thinking with mental images have a more limited diachronic tendency compared with individuals thinking with inner speech.

Methods

Adults (N = 309, Mage = 31.5 years, 76% women) with at least a high school degree were assessed with the Autism Spectrum Quotient, a test of diachronic tendency comprising four pictures varying in social interactivity and dynamicity, and a thinking style scale comprising three items representing three different everyday situations.

Results

The results showed that adults with many autistic traits have a limited diachronic tendency but only when the situation is socially interactive and dynamic, think more in mental images than individuals with no or few autistic traits but nevertheless still think more with inner speech than with mental images, and the more the participants reported thinking in inner speech, the more they evoked past and future events when describing a socially interactive and dynamic situation.

Conclusions

More autistic traits are associated with a limited diachronic tendency in socially interactive and dynamic situations and more thinking in mental images, and thinking style could be one of the determinants of diachronic tendency in socially interactive and dynamic situations.

Measuring business-level expectations and uncertainty: survey evidence and the COVID-19 pandemic
Authors: Chen Cheng , Senga Tatsuro , Zhang Hongyong
Published: July 2021

Utilizing a unique firm-level survey in Japan that contains five-bin forecasts for sales, we document three findings. First, firm-level subjective uncertainty is highly and positively related to volatility of past firm growth. Second, there are substantial variations in subjective uncertainty across firms, with a long right tail with extremely high subjective uncertainty. In addition, firms that have exposure to international businesses either through international trade or foreign direct investment have both higher average expected sales and subjective uncertainty. Finally, the sudden escalation of the COVID-19 pandemic in January–February 2020 led to a substantial increase in firms’ subjective uncertainty. Our triple-difference estimation results show that this effect is especially large for firms that have direct exposure to China through international trade and foreign direct investment.
The Cycle of Coalition
Authors: Fortunato David
Published: July 2021

How does coalition governance shape voters' perceptions of government parties and how does this, in turn, influence party behaviors? Analyzing cross-national panel surveys, election results, experiments, legislative amendments, media reports, and parliamentary speeches, Fortunato finds that coalition compromise can damage parties' reputations for competence as well as their policy brands in the eyes of voters. This incentivizes cabinet partners to take stands against one another throughout the legislative process in order to protect themselves from potential electoral losses. The Cycle of Coalition has broad implications for our understanding of electoral outcomes, partisan choices in campaigns, government formation, and the policy-making process, voters' behaviors at the ballot box, and the overall effectiveness of governance.
Art and the Arab Spring
Authors: Shilton Siobhan
Published: July 2021

The revolutions that began to sweep across countries in North Africa and the Middle East in December 2010 – like other revolutions in diverse modern historical contexts – have often been articulated, internally and externally, in black and white terms of success or failure, liberation or constraint, for or against, friend or enemy. These internal and external clichés are perpetuated by what Jellel Gasteli has called 'icons of revolutionary exoticism'. Paying particular attention to works from the Tunisian Revolution of 2011, this book examines a diverse body of art including photography, sculpture, graffiti, performance, video and installation by over twenty-five artists. Examining how art can evoke the idea of revolution, Art and the Arab Spring reveals a new way of understanding these revolutions, their profound cultural impact, and of the meaning of the term 'revolution' itself.
“Safe but Frozen Camps”: Syrian and Palestinian Refugees around a Football Field in Beirut
Authors: Fogliata Stefano
Published: July 2021

Palestinian camps in Lebanon have turned once more into “transitional zones of emplacement” for thousands of people recently fleeing the Syrian conflict. In this context, the plural subjectivities emerging within the camps highlight a further connection between spatial marginalization and precarious legal statuses. My research hinges on the interconnectivities evolving around the Palestinian Bourj el Barajneh camp and Hezbollah-controlled Beirut southern suburbs moving from an ethnographic insight of the Palestinian football society. Inside the “Refugee Football Leagues,” Palestinians, Syrians and Lebanese players find a space in leagues whose matches are mostly disputed within the numerous refugee camps scattered throughout the national territory. Moving from newcomers’ strategies for protection, the essay investigates how refugees living in camps experience different scales of mobility and develop a wide range of practices that extend beyond the camp's boundaries, exploring how imperceptible and hyper-mobile tactics of existence re-elaborate Palestinian refugee camps into meaningful places of elusive contestation.
The Deutschland Series: Cold War Nostalgia for Transnational Audiences
Authors: Gumbert Heather
Published: July 2021

How do you explain the Cold War to a generation who did not live through it? For Jörg and Anna Winger, co-creators and showrunners of the Deutschland series, you bring it to life on television. Part pop culture reference, part spy thriller, and part existential crisis, the Wingers’ Cold War is a fun, fast-paced story, “sunny and slick and full of twenty-something eye candy.” A coproduction of Germany's UFA Fiction and Sundance TV in the United States, the show premiered at the 2015 Berlinale before appearing on American and German television screens later that year. Especially popular in the United Kingdom, it sold widely on the transnational market. It has been touted as a game-changer for the German television industry for breaking new ground for the German television industry abroad and expanding the possibilities of dramatic storytelling in Germany, and is credited with unleashing a new wave of German (historical) dramas including Babylon Berlin, Dark, and a new production of Das Boot.
Improving perinatal sleep via a scalable cognitive behavioural intervention: findings from a randomised controlled trial from pregnancy to 2 years postpartum
Authors: Bei Bei , Pinnington Donna M. , Quin Nina , Shen Lin , Blumfield Michelle , Wiley Joshua F. , Drummond Sean P. A. , Newman Louise K. , Manber Rachel
Published: July 2021

Background

Sleep disturbance is common in gestational parents during pregnancy and postpartum periods. This study evaluated the feasibility and efficacy of a scalable cognitive behavioural therapy (CBT) sleep intervention tailored for these periods.

Methods

This is a two-arm, parallel-group, single-blind, superiority randomised controlled trial. Nulliparous females without severe medical/psychiatric conditions were randomised 1:1 to CBT or attention- and time-matched control. All participants received a 1 h telephone session and automated multimedia emails from the third trimester until 6 months postpartum. Outcomes were assessed with validated instruments at gestation weeks 30 (baseline) and 35 (pregnancy endpoint), and postpartum months 1.5, 3, 6 (postpartum endpoint), 12 and 24.

Results

In total, 163 eligible participants (age M ± s.d. = 33.35 ± 3.42) were randomised. The CBT intervention was well accepted, with no reported adverse effect. Intention-to-treat analyses showed that compared to control, receiving CBT was associated with lower insomnia severity and sleep disturbance (two primary outcomes), and lower sleep-related impairment at the pregnancy endpoint (p values ⩽ 0.001), as well as at 24 months postpartum (p ranges 0.012–0.052). Group differences across the first postpartum year were non-significant. Participants with elevated insomnia symptoms at baseline benefitted substantially more from CBT (v. control), including having significantly lower insomnia symptoms throughout the first postpartum year. Group differences in symptoms of depression or anxiety were non-significant.

Conclusions

A scalable CBT sleep intervention is efficacious in buffering against sleep disturbance during pregnancy and benefitted sleep at 2-year postpartum, especially for individuals with insomnia symptoms during pregnancy. The intervention holds promise for implementation into routine perinatal care.
Objective and subjective neighbourhood characteristics and suicidality: a multilevel analysis
Authors: Dykxhoorn Jennifer , Hayes Joseph , Ashok Kavya , Sörberg Wallin Alma , Dalman Christina
Published: July 2021

Background

Characteristics of the neighbourhood environment, including population density, social fragmentation, and trust, have been linked to mental health outcomes. Using a longitudinal population-based cohort, we explored the relationship between objective and subjective neighbourhood characteristics and the odds of suicidal thoughts and attempts.

Methods

We conducted a longitudinal study of 20764 participants living in Stockholm County who participated in the Stockholm Public Health Survey. We used multilevel modelling to examine if suicidal thoughts and attempts were associated with neighbourhood characteristics, independent of individual associations. We included objective and subjective measures to explore if there was a different relationship between these measures of the neighbourhood environment and suicidality.

Results

Associations between neighbourhood factors and suicidality were predominantly explained by individual characteristics, with the exception of neighbourhood-level deprivation and average residential trust. Each unit increase of deprivation was linked to increased odds of suicidal thoughts [Odds ratio (OR) 1.04, 95% confidence interval (CI) 1.00–1.07] and attempts (OR 1.11, 95% CI 1.06–1.17). Decreasing residential trust was associated with increased odds of suicide attempts (OR 1.09, 95% CI 1.02–1.17). There was no evidence that neighbourhood-level fragmentation or average trust in public and political institutions had an independent effect on suicidality once individual and sociodemographic factors were accounted for.

Conclusions

This study showed that much of the neighbourhood-level variation in suicidal thoughts and attempts could be explained by compositional factors, including sociodemographic clustering within neighbourhoods. The independent effect of neighbourhood-level deprivation and average residential trust provide evidence that the neighbourhood context may exert an independent effect on suicidality beyond the impact of individual characteristics.
Public Pension Generosity and Old-Age Poverty in OECD countries

Published: July 2021

Pension adequacy is gaining importance as old-age poverty remains a pressing problem. In many advanced welfare states, the population is ageing rapidly and recent pension reforms have led to cuts in public pension provision. There are, however, few comparative longitudinal studies on the relationship between pension generosity and old-age poverty. This study provides a comparative empirical assessment of how the prevalence and depth of old-age poverty relates to generosity of public pension benefits in 14 advanced OECD welfare states from 1980-2010. We focus on the role of mandatory public pension provision of mainly first tier schemes that grant the major share of retirees’ income in most countries. We use data on theoretical pension replacement rates for retirees who had different working-age incomes. In order to address endogeneity issues, we adopt an instrumental-variable approach. Our main finding shows that pensions systems and earnings-related schemes, in particular, are quite efficient in reducing the risk of old-age poverty. Yet they still do very little to alleviate poverty among those pensioners in the most disadvantaged situations. We also found that redistribution within the pension system does not substantially contribute to poverty alleviation.
HYPERLEXIS AND THE RULE OF LAW
Authors: Chiao Vincent
Published: July 2021

On a popular understanding, the rule of law is valuable because it enables people to plan their lives. However, planning conceptions of the rule of law are undermined by the sheer quantity of legal rules, regulations, and policies characteristic of modern administrative states. Under conditions of hyperlexis, people cannot reasonably be expected to reliably use the law as a guide to conduct. Rather than conclude that the rule of law is inimical to the administrative state, however, I defend an alternative conception of the rule of law. On what I term a contestatory conception, the rule of law requires an adequate opportunity to challenge decisions made by officials in the exercise of their legal powers. The animating idea of a contestatory conception of the rule of the law is that officials should relate to citizens in the space of reasons rather than merely through the exercise of power.
Barren lives: drought shocks and agricultural vulnerability in the Brazilian Semi-Arid

This paper studies the effects of drought shocks in a vulnerable environment – the Brazilian Semi-Arid. We analyze the impact of drought shocks, measured as deviations from long-run historical averages, on agricultural outcomes in a region that suffers recurrently from drought. After controlling for municipality and year fixed effects, we use weather shocks to exactly identify outcomes. Our benchmark results show substantial effects on the loss of crop area and on the value of agricultural output, as well as on crop yields. As we investigate distributional effects, our results show that crops related to familiar agriculture suffer more from drought shocks. We follow our investigation by testing heterogeneity effects and show that adequate water provision and maintenance of forest cover help in reducing the impact of drought shocks.
Markets and communities: the social cost of the meritocracy
Authors: Carvalho Jean-Paul
Published: July 2021

Critiques of the meritocracy have centered on its narrow definition and biased assessment of merit, its stigmatization of the unsuccessful, and excessive competition. This paper identifies a different mechanism that could have pernicious social and political consequences. Economic mobility sorts people based on certain ‘productive’ traits, separating them into classes, and thus alters social externalities. This sorting–separation–externalities mechanism can produce between-class polarization in social outcomes (e.g. alcoholism and drug abuse) and worsen aggregate outcomes over all classes, consistent with rising ‘deaths of despair’ in the United States (Case and Deaton, 2020,Deaths of Despair and the Future of Capitalism. Princeton University Press). When traits are endogenous, transition out of a caste-based society produces an initial burst of economic mobility which dissipates over time. Thus, a dynamic meritocratic society devolves into a static class-based society. I set out an alternative model called the ‘experimental society’, which is less susceptible to these problems.
Frank Knight, uncertainty and knowledge spillover entrepreneurship
Authors: Audretsch David B. , Belitski Maksim
Published: July 2021

In his seminal 1921 book,Risk, Uncertainty, and Profit, Frank Knight distinguished uncertainty and risk. This paper applies Knight's concept of uncertainty to knowledge generated in incumbent organizations to explain the inherent difficulty in assessing potential innovations along with the key role played by knowledge spillover entrepreneurship as a conduit for transforming new knowledge created by an incumbent organization but ultimately commercialized through the creation of a new firm and innovation. Knowledge is inherently uncertain and constitutes what is characterized as the knowledge filter impeding innovative activity in the context of incumbent firms and organizations. The organizational and institutional context and market uncertainty can either facilitate or impede the spillover of knowledge from the firm where it was created to the entrepreneurial startup where it is transformed into innovation. The empirical evidence based on a large, unbalanced panel of 9,126 UK firms constructed from six consecutive waves of a community innovation survey and annual business registry survey during 2002–2014. Implications for managers, scholars, and policymakers are provided.
CME-Sonografie 99/Antworten: Veränderungen der Nierenechogenität
Authors: Tuma Jan
Published: July 2021

Zusammenfassung. Normale Nieren haben eine glatte Kontur, Nierenlänge 9–12 cm, Volumen 90–180 ml/1,73 m2 Körperoberfläche, Parenchymbreite 13–18 mm sowie eine Echogenität der Rinde, die im Vergleich zu Leber und Milz echoärmer ist, sowie Markpyramiden, die gegenüber der Rinde erneut echoärmer sind. Digitale Ultraschallbilder ermöglichen eine Messung der Echogenität (Luminanz) zwischen 0 (schwarz) und 255 (weiss). Ein normaler Quotient zwischen der Echogenität der Leber und der Nierenrinde beträgt 1,0–1,4. Ein normaler Quotient zwischen Milz und Nierenrinde ist >1,0. Zwischen Nierenrinde und Nierenmark ist der normale Quotient >1,0. Bei diffusen Nierenparenchymerkrankungen werden Veränderungen der Echogenität beobachtet. Es gibt Nieren mit erhöhter Echogenität der Rinde und einem Quotienten gegenüber Leber und Milz von <1,0 sowie Nieren mit echoreichem Nierenmark und dem Quotienten zwischen Nierenrinde und Nierenmark <1,0.
Structural Controls Over the 2019 Ridgecrest Earthquake Sequence Investigated by High‐Fidelity Elastic Models of 3D Velocity Structures

Published: July 2021

We develop finite element models of the coseismic displacement field accounting for the 3D elastic structures surrounding the epicentral area of the 2019 Ridgecrest earthquake sequence containing two major events of Mw7.1 and Mw6.4. The coseismic slip distribution is inferred from the surface displacement field recorded by interferometric synthetic aperture radar. The rupture dip geometry is further optimized using a novel nonlinear‐crossover‐linear inversion approach. It is found that accounting for elastic heterogeneity and fault along‐strike curvilinearity improves the fit to the observed displacement field and yields a more accurate estimate of geodetic moment and Coulomb stress changes. We observe spatial correlations among the locations of aftershocks and patches of high slip, and rock anomalous elastic properties, suggesting that the shallow crust's elastic structures possibly controlled the Ridgecrest earthquake sequence. Most of the coseismic slip with a peak slip of 7.4 m at 3.6 km depth occurred above a zone of reduced S‐wave velocity and significant post‐Mw7.1 afterslip. This implies that viscous materials or fluid presence might have contributed to the low rupture velocity of the mainshock. Moreover, the zone of high slip on the northwest‐trending fault segment is laterally bounded by two aftershock clusters, whose location is characterized by intermediate rock rigidity. Notably, some minor orthogonal faults consistently end above a subsurface rigid body. Overall, these observations of structural controls improve our understandings of the seismogenesis within incipient fault systems.
