Einsam(er) seit der Coronapandemie: Wer ist besonders betroffen? – psychologische Befunde aus Deutschland
Authors: Lippke Sonia , Keller Franziska , Derksen Christina , Kötting Lukas , Ratz Tiara , Fleig Lena
Published: March 2021

Hintergrund

Soziale Isolation ist ein Risikofaktor für Einsamkeit und damit für gesundheitliche Beeinträchtigungen. Veränderungen im Zusammenhang mit der Coronapandemie in Deutschland gilt es besser zu verstehen.

Fragestellung

Ziel der Studie war es, Einsamkeit und assoziierte Faktoren vor und während der Coronapandemie in Deutschland systematisch zu untersuchen. Die Fragestellungen waren: 1. Wie einsam fühlen sich Menschen vor und während der Coronapandemie? 2. Wie viele Menschen fühlen sich seit Beginn der Coronapandemie einsamer? 3. Wie viele Menschen berichten über gesundheitliche Belastungen während der Coronapandemie?

Material und Methoden

Im Jahr 2019 (vor der Coronapandemie) wurden 1003 und im Jahr 2020 (während der Coronapandemie) 1050 Erwachsene online befragt (51 % Frauen; 18–90 Jahre).

Ergebnisse

Es fühlten sich 10,8 % vs. 26,6 % der Befragten vor bzw. seit der Coronapandemie mehrfach pro Woche oder täglich einsam. Alleinlebende, Frauen und Jüngere fühlten sich häufiger einsam. Seit der Coronapandemie fühlten sich 30,8 % einsamer, v. a. Jüngere. Von starken gesundheitlichen Belastungen berichteten 18,9 %, dies hing mit jüngerem Alter, verschiedenen Sorgen/Ängsten und Einsamkeit zusammen.

Diskussion

Die höhere Ausprägung der Einsamkeit und Sorgen während der Coronapandemie sollte bei verhaltensbezogenen Maßnahmen zur Prävention der psychischen und körperlichen Beeinträchtigungen sowie behördlichen Maßnahmen berücksichtigt werden. Jüngere Menschen und Alleinlebende könnten profitieren, indem sie zu gezielten Bewältigungsstrategien (z. B. angemessener Nutzung digitaler Medien) ermutigt werden.
Can a dam type of an alpine lake be derived from lake geometry? A negative result
Authors: Emmer Adam , Cuřín Vojtěch
Published: March 2021

Glacial lake outburst floods (GLOFs) represent one of the most serious hazard and risk in deglaciating high mountain regions worldwide and the need for GLOF hazard and risk assessment is apparent. As a consequence, numerous region- and nation-wide GLOF assessment studies have been published recently. These studies cover large areas and consider hundreds to thousands of lakes, prioritizing the hazard posed by them. Clearly, certain simplification is required for executing such studies, often resulting in neglecting qualitative characteristics which would need manual assignment. Different lake dam types (e.g., bedrock-dammed, moraine-dammed) are often not distinguished, despite they control GLOF mechanism (dam overtopping/dam breach) and thus GLOF magnitude. In this study, we explore the potential of easily measurable quantitative characteristics and four ratios to approximate the lake dam type. Our dataset of 851 lakes of the Cordillera Blanca suggests that while variances and means of these characteristics of individual lake types differ significantly (F-test, t-test), value distribution of different geometrical properties can’t be used for the originally proposed purpose along the spectra. The only promising results are obtained for extreme values (selected bins) of the ratios. For instance, the low width to length ratio indicates likely moraine-dammed lake while the high value of ratio indicating round-shape of the lake indicates increased likelihood of bedrock-dammed lake. Overall, we report a negative result of our experiment since there are negligible differences of relative frequencies in most of the bins along the spectra.
The Influence of 3d and 4d Transition Metals on the Glass Forming Ability of Ternary FeCo-Based Alloys
Authors: Śniadecki Z.
Published: March 2021

Thermodynamic modeling was used to determine enthalpies of formation and other thermodynamic parameters describing glass forming ability of Fe-Co-TM (TM = V, Nb, Cr, Mo) alloys. FeCo-based alloys are considered as candidates for applications as high magnetic flux density materials due to their high magnetic saturation and low magnetic anisotropy. Nevertheless, mechanical properties, especially the lack of ductility, are their main weakness. Therefore, further optimization by vitrification, further heat treatment and alloying should be considered. As the most crucial step is the synthesis of amorphous precursors, discussion is concentrated on the effect of transition metal substitution on the glass forming ability. The highest glass forming ability was reported for Fe-Co-Nb alloys. It can be also noted that the driving force for vitrification can be improved by substitution of Fe by other transition elements, as glass forming ability parameter ∆P

Particulate matter 10 (PM10): persistence and trends in eight European capitals
Authors: Caporale Guglielmo Maria , Gil-Alana Luis A. , Carmona-González Nieves
Published: March 2021

This paper examines the statistical properties of daily PM10in eight European capitals (Amsterdam, Berlin, Brussels, Helsinki, London, Luxembourg, Madrid and Paris) over the period 2014–2020 by applying a fractional integration framework; this is more general than the standard approach based on the classical dichotomy between I(0) stationary and I(1) non-stationary series used in most other studies on air pollutants. All series are found to be characterised by long memory and fractional integration, with orders of integration in the range (0, 1), which implies that mean reversion occurs and shocks do not have permanent effects. Persistence is the highest in the case of Brussels, Amsterdam and London. The presence of negative trends in Brussels, Paris and Berlin indicates some degree of success in reducing pollution in these capitals.
Friend or foe?—comparing party reactions to Fridays for Future in a party system polarised between AfD and Green Party
Authors: Berker Lars E. , Pollex Jan
Published: March 2021

Fridays for Future has risen as a new environmental movement pushing politicians to take action against climate change. However, its interaction with other political actors, most importantly political parties, has hardly been addressed systematically by scientific research. In this article, we take stock of party reactions to the movement on the national and subnational level in Germany. Furthermore, we investigate possible explanations for variances in these reactions in a comparison of subnational party organisations and thereby, focus on dynamics of party competition, especially on the impact of the Green Party as established contender and of the populist radical right AfD and its new role in environmental politics. We show that party reactions to the movement vary widely reflecting a clear divide on the left-right-spectrum. While centre-left parties, particularly the Green Party, support the movement, centre-right parties are utmost cautious and the populist radical right AfD stands out with a blatantly hostile attitude. Though indications for the impact of party competition dynamics were minor, we observed a strong polarisation on the climate issue that may take effect in the near future.
Development of Groundwater Irrigation in Telangana State: Challenges, Management and Way Forward
Authors: Madhnure Pandith , B. Lavanya
Published: March 2021

Groundwater based irrigation, which was started in India as early as “Indus Civilizations” got impetus during 3rd five-year plan. In India, at present 78 m ha of irrigation potential is created and 80 percent is utilized. One of the World’s highest user of groundwater is India with 63 percent of its dynamic groundwater resources. Similarly, Telangana State is also utilizing the dynamic groundwater resources up to 65 percent. Groundwater a reliable source of irrigation with high yields and brings equity among its users as ~99 % of structures are owned by individuals. In the state, well irrigation increased from ~0.46 lakh ha from 1875 to 23.35 lakh ha during 2017-18 and well density increased to ~13 wells/ km2 leading to decrease in irrigation potential under each well to < 1 ha. As a result of it many challenges like water logging & salinity in canal command areas, over-exploitation leading to de-saturation of shallow aquifers, underutilization in north eastern part, groundwater pollution (both geogenic and anthropogenic) and sustainability, etc have cropped up. The management steps taken up in water sector like water transfer through KLIP, providing protected water supply through Mission Bhagiratha, de-siltation through Mission Kakatiya, forest rejuvenation through Haritha Haram, construction of various ARS, modernization of canals, conjunctive use of surface and groundwater, user centred aquifer level groundwater management, tank management, IEC activities etc brought positive changes in water availability in the state more particularly surface water. In order to sustain these efforts, formation of WUA at watershed/village level for agricultural planning, change in cropping pattern from highly intensive paddy to ID crops more particularly from non-command areas, conjunctive use of water, warabandhi (on/off) method of releasing irrigation water, developing intercepting drains, soil treatment, declaring crop holidays, separate electric grids for agriculture and domestic supply, legally separating water and land rights and strict implementation of regulatory measures. The other measures suggested are policy interventions that involve regulatory mechanisms and linking village-based institutions to government departments that manage groundwater etc.
VSI LC filter optimized by a genetic algorithm from connected to island microgrid operation
Authors: Lopez Juan R. , Cruz Pedro Ponce , Gutierrez Arturo Molina
Published: March 2021

In microgrids (MG) with a high penetration of renewable energy sources (RES) power converters are used to regulate the produced energy to a single voltage and frequency reference value across the MG. Adequate incorporation of an LC filter at the output of power electronic devices allows the attenuation of harmful harmonics that can be introduced to the MGs energy bus. By traditional methods, LC filter values can be calculated by means of the power rating, switching frequency, cutoff frequency, and using the bode frequency domain. Nonetheless, in the transition from a connected to an autonomous MG operation, the calculated LC filter can lead to high harmonic injection. As a result, a tuning methodology capable of obtaining the right set of parameters for the LC filter for a transition event can improve the performance of the MG. This work optimizes the LC output parameters with respect to the size of the filter components, the IEEE Std 519-2014, and bandwidth of the filter, within a bounded region of values subjected to performance conditions such as voltage output, and the produced total harmonic distortion (THD) measurements during the transition from a connected to an autonomous operation. In a case study, genetic algorithm optimization is used to obtain the LC filter parameters and compared to a conventional arithmetic methodology to obtain the values of the filter. The optimization results in a set of values that lead to a higher harmonic attenuation after the transition rather than a conventional method using the switching frequency as the main design factor.
Clinical genetics in transition—a comparison of genetic services in Estonia, Finland, and the Netherlands

Published: March 2021

Genetics has traditionally enabled the reliable diagnosis of patients with rare genetic disorders, thus empowering the key role of today’s clinical geneticists in providing healthcare. With the many novel technologies that have expanded the genetic toolkit, genetics is increasingly evolving beyond rare disease diagnostics. When placed in a transition context—like we do here—clinical genetics is likely to become a fully integral part of future healthcare and clinical genetic expertise will be required increasingly outside traditional clinical genetic settings. We explore transition effects on the thinking (culture), organizing (structure), and performing (practice) in clinical genetics, taking genetic healthcare in Estonia, Finland, and the Netherlands as examples. Despite clearly distinct healthcare histories, all three countries have initially implemented genetic healthcare in a rather similar fashion: as a diagnostic tool for predominantly rare congenital diseases, with clinical geneticists as the main providers. Dynamics at different levels, such as emerging technologies, biobanks and data infrastructure, and legislative frameworks, may require development of a new system attuned with the demands and (historic) context of specific countries. Here, we provide an overview of genetic service provisions in Estonia, Finland, and the Netherlands to consider the impact of historic and recent events on prospective developments in genetic healthcare.
Failure mode analysis on compression of lattice structures with internal cooling channels produced by laser powder bed fusion

Published: March 2021

Conformal cooling coils have been developed during the last decades through the use of additive manufacturing (AM) technologies. The main goal of this study was to analyze how the presence of an internal channel that could act as a conformal cooling coil could affect compressive strength and quasi-elastic gradient of AlSi10Mg lattice structures produced by laser powder bed fusion (LPBF). Three different configurations of samples were tested in compression at 25 °C and 200 °C. The reference structures were body centered cubic (BBC) in the core of the samples with vertical struts alongZ(BCCZ) lattices in the outer perimeter, labelled as NC samples. The main novelty consisted in inserting a straight elliptical channel and a 45° elliptical channel inside the BCCZ lattice structures, labelled as SC and 45C samples respectively. All the samples were then tested in as-built (AB) condition, and after two post process heat treatments, commonly used for AlSi10Mg LPBF industrial components, a stress relieving (SR) and a T6 treatment. NC lattice structures AB exhibited an overall fragile fracture and therefore the SC and 45C configuration samples were tested only after thermal treatments. The test at 25 °C showed that all types of samples were characterized by negligible variations in their quasi-elastic gradients and yield strength. On the contrary, the general trend of stress-strain curves was influenced by the presence of the channel and its position. The test at 200 °C showed that NC, SC and 45C samples after SR and T6 treatments exhibited a metal-foam like deformation.
Exploring associations between personality trait facets and emotional, psychological and social well-being in eating disorder patients
Authors: de Vos Jan Alexander , Radstaak Mirjam , Bohlmeijer Ernst T. , Westerhof Gerben J.
Published: March 2021

Purpose

Personality functioning is strongly linked to well-being in the general population. Yet, there is a lack of scientific knowledge about the pathways between personality trait facets and emotional, psychological and social well-being in ED patients. The general aim was to examine potential associations between maladaptive personality trait facets and the three main dimensions of well-being.

Methods

Participants were 1187 female eating disorder patients who were referred for specialized treatment. Patients were diagnosed with anorexia nervosa (31.7%), bulimia nervosa (21.7%), binge eating disorder (11%) and other specified eating disorders (35.5%). The Personality Inventory for the DSM 5 (PID-5) was used to measure 25 trait facets, and well-being was measured with the Mental Health Continuum Short Form (MHC-SF). Multiple hierarchical regression analyses were applied to examine potential associations between personality and well-being while controlling for background and illness characteristics.

Results

Personality trait facets led to a statistically significant increase of the explained variance in emotional (38%), psychological (39%), and social well-being (26%) in addition to the background and illness characteristics. The personality trait facets anhedonia and depression were strongly associated with all three well-being dimensions.

Conclusion

Personality traits may play an essential role in the experience of well-being among patients with EDs. To promote overall mental health, it may be critical for clinicians to address relevant personality trait facets, such as anhedonia and depression, associated with well-being in treatment.

Authors: Di Capua Beatrice , Bellieni Andrea , Fusco Domenico , Gambacorta Maria Antonietta , Tagliaferri Luca , Villani Emanuele Rocco , Bernabei Roberto , Valentini Vincenzo , Colloca Giuseppe Ferdinando
Published: March 2021

Background

Population of oldest old will grow dramatically in the next future and cancer, physiologically related to aging, will be very prevalent among them. Lack of evidence is a huge problem to manage cancer in oldest old and will be more and more in the next years.

Aims

Our purpose was to investigate the characteristics of a population of oldest old patients with cancer treated in the Radiation Oncology Unit of Fondazione Policlinico A. Gemelli IRCCS.

Methods

We conducted a retrospective study. The primary outcome was to evaluate which characteristics of the population could influence the choice of oncological treatment (with radical or non-radical intent).

Results

We identified a total of 348 patients: 140 were on follow-up; 177 were under treatment; 31 were considered not eligible for treatments. Patients under treatment had a high comorbidity index (mean Charlson Comorbidity Index 5.4), and a high prevalence of polypharmacy (mean number of drugs 5.6). More than half (53.1%) was treated with radical intent. Patients treated with radical intent were 1 year younger (87.1 years old vs 88.1 years old), more performant (ECOG 0.7 vs 1.3), and had less prevalence of metastatic neoplasia (6.4% vs 34.9%); comorbidities and drugs did not show differences in the two groups.

Conclusion

Oldest old, usually not considered in international guidelines, are treated for oncological disease, often with radical intent. The treatment seems not to be tailored considering comorbidities but on performance status.

Published: March 2021

The proliferation of information and communication technologies (ICT) in the twenty-first century has challenged the status quo of educational setting and led to a paradigm shift in teaching and learning processes. ICT use and integration in teaching then, becomes an essential component of pedagogical processes to have an effective teacher–student interaction and to optimize learning. While past studies have already established evidence that attitude toward ICT (will), ICT skills (skill), and availability of ICT resources (tool) elements are indeed important contributors to the integration of ICT in teaching, little attention has been paid yet to differences in these elements and in this model of ICT integration between subject areas of science and mathematics. Thus, this study aims to examine the significant differences in these factors between science and mathematics (S&M) teaching guided by the Will–Skill–Tool (WST) model developed by Christensen and Knezek (2001, 2008). Using independent samples t test and multiple linear regression, results show that science teachers had higher scores in will, skill, tool, and ICT integration indices compared to mathematics teachers. Findings also revealed that WST model of ICT integration differs between science and mathematics areas, particularly in terms of which among the factors had the strongest influence on ICT integration. The study recommends distinct approaches in providing capacity training development on ICT integration for teachers considering the context of subject specific area.
Exploration on molecular dynamics simulation methods of microscopic wetting process for coal dust
Authors: Zhang Qi , Chen Xinyi , Wang Hetang , Xu Chaohang
Published: March 2021

Wet dust removal is one of the main technical measures in coal dust control, and coal dust wetting is the key factor to determine the effect of wet dust removal. In order to explore the micro-wetting process of coal dust, this paper uses molecular dynamics simulation to study the micro-wetting process of coal dust in different simulation conditions. The molecular dynamics simulation was carried out under different ensemble, thermodynamic states as well as relaxation pretreatment methods, then the H2O molecular layer and coal dust molecular layer in each simulation were quantitatively analyzed by relative concentration. The research results show that a method for establishing molecular model of lignite is proposed and the 2D periodic surface structure is more reasonable. The surface system of coal-H2O molecule is established by NVT aeration method, where the simulation result is close to the actual coal dust wetting process. The simulation effect of medium and large coal dust-H2O molecular system is better than that of small coal dust-H2O molecular system. This study provides a new solution for changing the empirical method of molecular dynamics simulation of coal system wetting and oversimplification of coal system.

Published: March 2021

Single-cell mass cytometry (SCMC) combines features of traditional flow cytometry (i.e., fluorescence-activated cell sorting) with mass spectrometry, making it possible to measure several parameters at the single-cell level for a complex analysis of biological regulatory mechanisms. In this study, we optimized SCMC to analyze hemocytes of the Drosophila innate immune system. We used metal-conjugated antibodies (against cell surface antigens H2, H3, H18, L1, L4, and P1, and intracellular antigens 3A5 and L2) and anti-IgM (against cell surface antigen L6) to detect the levels of antigens, while anti-GFP was used to detect crystal cells in the immune-induced samples. We investigated the antigen expression profile of single cells and hemocyte populations in naive states, in immune-induced states, in tumorous mutants bearing a driver mutation in the Drosophila homologue of Janus kinase (hopTum) and carrying a deficiency of the tumor suppressor gene lethal(3)malignant blood neoplasm-1 [l(3)mbn1], as well as in stem cell maintenance-defective hdcΔ84 mutant larvae. Multidimensional analysis enabled the discrimination of the functionally different major hemocyte subsets for lamellocytes, plasmatocytes, and crystal cells, and delineated the unique immunophenotype of Drosophila mutants. We have identified subpopulations of L2+/P1+ and L2+/L4+/P1+ transitional phenotype cells in the tumorous strains l(3)mbn1 and hopTum, respectively, and a subpopulation of L4+/P1+ cells upon immune induction. Our results demonstrated for the first time that SCMC, combined with multidimensional bioinformatic analysis, represents a versatile and powerful tool to deeply analyze the regulation of cell-mediated immunity of Drosophila.
Control Theory for Physicists
Authors: Bechhoefer John
Published: March 2021

Control theory, an interdisciplinary concept dealing with the behaviour of dynamical systems, is an important but often overlooked aspect of physics. This is the first broad and complete treatment of the topic tailored for physicists, one which goes from the basics right through to the most recent advances. Simple examples develop a deep understanding and intuition for the systematic principles of control theory, beyond the recipes given in standard engineering-focused texts. Up-to-date coverage of control of networks and complex systems, and a thorough discussion of the fundamental limits of control, including the limitations placed by causality, information theory, and thermodynamics are included. In addition it explores important recent advances in stochastic thermodynamics on the thermodynamic costs of information processing and control. For all students of physics interested in control theory, this classroom-tested, comprehensive approach to the topic with online solutions and further materials delivers both fundamental principles and current developments.

Looking at the past, present and future, the author suggests a paradigm shift starting from the common ground in order to propose a better future for environmental law in Muslim countries. As the first book to compare Shari'a and common law in field of environmental protection, it suggests a new path in comparative environmental law by recognizing the contributions of both history and spirituality.
Seeing Us in Them
Authors: Sirin Cigdem V. , Valentino Nicholas A. , Villalobos José D.
Published: March 2021

What causes some people to stand in solidarity with those from other races, religions, or nationalities, even when that solidarity does not seem to benefit the individual or their group? Seeing Us in Them examines outgroup empathy as a powerful predisposition in politics that pushes individuals to see past social divisions and work together in complex, multicultural societies. It also reveals racial/ethnic intergroup differences in this predisposition, rooted in early patterns of socialization and collective memory. Outgroup empathy explains why African Americans vehemently oppose the border wall and profiling of Arabs, why Latinos are welcoming of Syrian refugees and support humanitarian assistance, why some white Americans march in support of Black Lives Matter through a pandemic, and even why many British citizens oppose Brexit. Outgroup empathy is not naïve; rather it is a rational and necessary force that helps build trust and maintain stable democratic norms of compromise and reciprocity.
Applying Risk Management Concepts from CRM and the Outdoor Recreation Industry to Academic Archaeology Projects
Authors: White William A.
Published: March 2021

Field safety is being taken more seriously across the cultural resource management (CRM) industry as CRM companies seek to be in compliance with their clients’ health and safety programs and to keep employees safe. Many universities also have organizational health and safety programs designed to protect students and employees, but academic archaeology is routinely conducted without adequate risk management planning. Risk management will be a workplace concern for aspiring archaeologists after graduating from college, which is why it is important for academic archaeology to meet industry standards. Archaeology can learn a great deal about fieldwork risk management from the outdoor recreation industry, which emphasizes building leadership skills rather than following proscribed rules and regulations to mitigate the myriad hazards in the field. This article provides some suggestions that academic archaeologists can use to apply risk management concepts from CRM and the outdoor recreation industry to academic projects in order to comply with university requirements and the Occupational Safety and Health Administration (OSHA), as well as to teach students how to be safe in the field.
Digital Data and Data Literacy in Archaeology Now and in the New Decade
Authors: Kansa Eric , Kansa Sarah Whitcher
Published: March 2021

OVERVIEW

Digital data play an increasingly important role in how we understand the present and the past. The challenges inherent in understanding and using digital data are as intellectually demanding as any other archaeological research endeavor. For these reasons, data management cannot be regarded as a simple compliance or technical issue. For data to be meaningfully preserved and used in intellectually rigorous ways, they need to be integrated fully into all aspects of archaeological practice, including ethics, teaching, and publishing. In this review, we highlight some of the significant and multifaceted challenges involved in managing data, including documentation, training, methodology, data modeling, trust, and ethical concerns. We then focus on the importance of building data literacy broadly among archaeologists so that we can manage and communicate the data our discipline creates. This involves more than learning to use a new tool or finding a data manager for one's excavation or survey. Long-term, responsible stewardship of data requires understanding the workflows and human roles in data management. Putting effort now into thoughtful data management and broad data-literacy training means we will be able to make the most of the “bigger” data that archaeologists now produce. An important aspect of this reorientation will be to look beyond the boundaries of our own research projects and information systems. Future research, teaching, and public engagement needs will also compel us to explore how our data articulates with wider contexts—within and beyond our discipline.
Nietzsche: Metaphysician
Authors: REMHOF JUSTIN
Published: March 2021

Perhaps the most fundamental disagreement concerning Nietzsche's view of metaphysics is that some commentators believe Nietzsche has a positive, systematic metaphysical project, and others deny this. Those who deny it hold that Nietzsche believes metaphysics has a special problem, that is, a distinctively problematic feature that distinguishes metaphysics from other areas of philosophy. In this paper, I investigate important features of Nietzsche's metametaphysics in order to argue that Nietzsche does not, in fact, think metaphysics has a special problem. The result is that, against a long-standing view held in the literature, we should be reading Nietzsche as a metaphysician.

Published: March 2021

Background:

The effectiveness of mechanical thrombectomy (MT) in elderly stroke patients remains debated. We aimed to describe outcomes and their predictors in a cohort of patients aged ≥ 85 years treated with MT.

Methods:

Data from consecutive patients aged ≥ 85 years undergoing MT at two stroke centers between January 2016 and November 2019 were reviewed. Admission National Institutes of Health Stroke Scale (NIHSS), pre-stroke, and 3-month modified Rankin scale (mRS) were collected. Successful recanalization was defined as modified thrombolysis in cerebral ischemia score ≥ 2b. Good outcome was defined as mRS 0–3 or equal to pre-stroke mRS at 3 months.

Results:

Of 151 included patients, successful recanalization was achieved in 74.2%. At 3 months, 44.7% of patients had a good outcome and 39% had died. Any intracranial hemorrhage (ICH) and symptomatic ICH occurred in 20.3% and 3.6%, respectively. Logistic regression analysis identiﬁed lower pre-stroke mRS score (adjusted odds ratio [aOR], 0.52; 95% CI, 0.36–0.76), lower admission NIHSS score (aOR, 0.90; 95% CI, 0.83–0.97), successful recanalization (aOR, 3.65; 95% CI, 1.32–10.09), and absence of ICH on follow-up imaging (aOR, 0.42; 95% CI, 0.08–0.75), to be independent predictors of good outcome. Patients with successful recanalization had a higher proportion of good outcome (45.3% vs 34.3%, p = 0.013) and lower mortality at 3 months (35.8% vs 48.6%, p = 0.006) compared to patients with unsuccessful recanalization.

Conclusions:

Among patients aged ≥ 85 years, successful recanalization with MT is relatively common and associated with better 3-month outcome and lower mortality than failed recanalization. Attempting to achieve recanalization in elderly patients using MT appears reasonable.
More than a century of direct glacier mass-balance observations on Claridenfirn, Switzerland
Authors: Huss Matthias , Bauder Andreas , Linsbauer Andreas , Gabbi Jeannette , Kappenberger Giovanni , Steinegger Urs , Farinotti Daniel
Published: March 2021

Glacier mass-balance observations at seasonal resolution have been performed since 1914 at two sites on Claridenfirn, Switzerland. The measurements are the longest uninterrupted records of glacier mass balance worldwide. Here, we provide a complete re-analysis of the 106-year series (1914–2020), focusing on both point and glacier-wide mass balance. The approaches to evaluate and homogenize the direct observations are described in detail. Based on conservative assumptions, average uncertainties of$\pm$0.25 m w.e. are estimated for glacier-wide mass balances at the annual scale. It is demonstrated that long-term variations in mass balance are clearly driven by melting, whereas decadal changes in accumulation are uncorrelated with mass balance and can only be relevant in short periods. Mass change of Claridenfirn is impacted by dry calving at a frontal ice cliff. Considerations of ice volume flux at a cross-profile reveal long-term variations in frontal ice loss accounting for$\sim$9% of total annual ablation on average. The effect of changes in frontal ablation mostly explains$\lt$10% of the mass-balance difference relative to the period 1960–1990, but accounts for$\sim$20% in 2010–2020. Glacier mass changes are discussed in the context of observations throughout the European Alps indicating that Claridenfirn is regionally representative.
The traceback method in child language acquisition research: identifying patterns in early speech
Authors: HARTMANN STEFAN , KOCH NIKOLAS , QUICK ANTJE ENDESFELDER
Published: March 2021

abstract

This paper discusses the traceback method, which has been the basis of some influential papers on first language acquisition. The method sets out to demonstrate that many or even all utterances in a test corpus (usually the last two sessions of recording) can be accounted for with the help of recurrent fixed strings (likeWhat’s that?) or frame-and-slot patterns (like [What’sX?]) that can also be identified in the remaining dataset (i.e., the previous sessions of recording). This is taken as evidence that language learning is much more item-based than previously assumed. In the present paper we sketch the development of the method over the last two decades, and discuss its relation to usage-based theory, as well as the cognitive plausibility of its components, and we highlight both its potential and its limitations.
Turkey’s queer times: epistemic challenges
Authors: Savcı Evren
Published: March 2021

This article suggests that Turkey’s queer times are co-constitutive with Jasbir Puar’s queer times of homonationalism. If the queer times of homonationalism correspond to a folding of some queers into life and respectability at the cost of rising Islamophobia in the “West,” Turkey’s queer times witnessed the increasing marginalization and “queering” of variously respectable subjects in the name of Islam and strong LGBT organizing against such marginalization. It discusses the epistemic challenges of studying Turkey’s queer times that stem from a theoretical suspicion that “queer” operates as a tool of colonial modernity when it spreads to the “non-West,” a suspicion that is due both to a perception of Islam as a target and victim of Western neocolonialism and to an ahistorical and rigidly discursive understanding of language. In turn, scholarship on Turkey’s queer times has the potential to truly transnationalize queer studies, both getting us out of the binaries of global–local, colonial–authentic, and West–East and reminding scholars that hegemonies are scattered.
Out on the fringe: Wales and the history of science
Authors: Morus Iwan Rhys
Published: March 2021

Imagine a scene sometime in the 1750s in the depths of west Wales. This was wild country. Even a century later, George Borrow called it a ‘mountainous wilderness … a waste of russet-coloured hills, with here and there a black craggy summit’. Through this desolation rides the Reverend William Williams. As he rode, he read – and the book in his saddlebags on this occasion was William Derham'sAstro-Theology, first published some twenty years earlier. Williams was a leading figure in the Methodist revolution that had been sweeping through Wales for the past two decades. Disenchanted with an Anglican Church that seemed increasingly disconnected – culturally and linguistically – from their everyday lives, and attracted by powerful and charismatic preachers like Williams himself, men and women across Wales turned to Methodism. They organized themselves into local groups worshipping in meeting houses rather than in their parish churches. Leaders like Williams usually had a number of such groups under their care, and spent much of their time on horseback, travelling between widely scattered communities to minister to their congregations. That Williams read in the saddle is well known. As shall become clear, he had certainly read Derham's book as well. It is not too much of an imaginative leap, therefore, to picture him reading about God's design of the cosmos as he rode through the Welsh hills – and it is a good image with which to begin a discussion about Wales, science and European peripheries.

We record for the first time a nominal species of the genusMicrosclerodermain the Western Atlantic, and the first record of the genusAmphibleptulain Mexico. Two new species of ‘lithistid’ Tetractinellida are described:Microscleroderma mexicasp. nov. from crevices of two reefs in Veracruz, Mexico, andAmphibleptula aaktunsp. nov. from the anchialine cave El Aerolito, Cozumel Island, Mexico.Microscleroderma mexicasp. nov. is characterized by its tubular and cup-shaped to wavy laminar habitus, hirsute surface and two size categories of oxea diactines.Amphibleptula aaktunsp. nov. is characterized by its ficiform or lobular habitus with an exhalant area at the flat top of the body, divided into numerous vertical septa-like structures; its desmas have thinner epirhabds, and thinner oxea than those ofAmphibleptula madrepora. This is the second species ofAmphibleptulathat has been described; hence, we propose the redefinition of the genus. Both species described have a shallow distribution (≤21 m depth); they are differentiated from each other by the disjunction between their habitats as well as by their morphology.

Background

Individuals diagnosed with psychiatric disorders who are prescribed antipsychotics have lower rates of violence and crime but the differential effects of specific antipsychotics are not known. We investigated associations between 10 specific antipsychotic medications and subsequent risks for a range of criminal outcomes.

Methods

We identified 74 925 individuals who were ever prescribed antipsychotics between 2006 and 2013 using nationwide Swedish registries. We tested for five specific first-generation antipsychotics (levomepromazine, perphenazine, haloperidol, flupentixol, and zuclopenthixol) and five second-generation antipsychotics (clozapine, olanzapine, quetiapine, risperidone, and aripiprazole). The outcomes included violent, drug-related, and any criminal arrests and convictions. We conducted within-individual analyses using fixed-effects Poisson regression models that compared rates of outcomes between periods when each individual was either on or off medication to account for time-stable unmeasured confounders. All models were adjusted for age and concurrent mood stabilizer medications.

Results

The relative risks of all crime outcomes were substantially reduced [range of adjusted rate ratios (aRRs): 0.50–0.67] during periods when the patients were prescribed antipsychotics v. periods when they were not. We found that clozapine (aRRs: 0.28–0.44), olanzapine (aRRs: 0.46–0.72), and risperidone (aRRs: 0.53–0.64) were associated with lower arrest and conviction risks than other antipsychotics, including quetiapine (aRRs: 0.68–0.84) and haloperidol (aRRs: 0.67–0.77). Long-acting injectables as a combined medication class were associated with lower risks of the outcomes but only risperidone was associated with lower risks of all six outcomes (aRRs: 0.33–0.69).

Conclusions

There is heterogeneity in the associations between specific antipsychotics and subsequent arrests and convictions for any drug-related and violent crimes.
NEITHER ABSOLUTISM NOR NEGOTIATION: SPANISH EMPIRE BUILDING AND POLITICAL ECONOMY IN THE 18THCENTURY CARIBBEAN
Authors: Bohorquez J.
Published: March 2021

This paper revisits the political economy during Spanish rule in America by reappraising the allegedly positive impact that intra-imperial transfers (situados) had on the Caribbean economy. It raises concerns concerning categories such as bargaining and absolutism and their accuracy in accounting for the nature of Spanish imperial rule. Three main findings are reported. Firstly, it seems inaccurate to hold that all remittances were injected into the economy with positive effects. Liquidity apparently provoked a real estate bubble. Secondly, the local market was not necessarily sensitive to the arrival of bullion. Finally, jurisdictional fragmentation allowed the king to issue debt in a disorderly fashion and with no constraints, and local officials and groups of interests to behave as free riders.
Escaping theTrap: Losing the Northern Cities Shift in Real Time
Authors: Thiel Anja , Dinkin Aaron J.
Published: March 2021

We examine the loss of the Northern Cities Shift raising oftrapin Ogdensburg, a small city in rural northern New York. Although data from 2008 showed robusttrap-raising among young people in Ogdensburg, in data collected in 2016 no speakers clear the 700-Hz threshold for NCS participation in F1 oftrap—a seemingly very rapid real-time change. We find apparent-time change in style-shifting: although older people raisetrapmore in wordlist reading than in spontaneous speech, younger people do the opposite. We infer that increasing negative evaluation of the feature led Ogdensburg speakers to collectively abandon raisingtrapbetween 2008 and 2016. This indicates a role for communal change in the transition of a dialect feature from an indicator to a marker.
Extracting possessions from text: Experiments and error analysis
Authors: Chinnappa Dhivya , Blanco Eduardo
Published: March 2021

This paper presents a corpus and experiments to mine possession relations from text. Specifically, we target alienable and control possessions and assign temporal anchors indicating when a possession relation holds between the possessor and possessee. We work with intra-sentential possessor and possessees that satisfy lexical and syntactic constraints. We experiment with traditional classifiers and neural networks to automate the task. In addition, we analyze the factors that help to determine possession existence and possession type and common errors made by the best performing classifiers. Experimental results show that determining possession existence relies on the entire sentence, whereas determining possession type primarily relies on the verb, possessor and possessee.
Regulators and environmental groups: better together or apart?
Authors: Espinola-Arredondo Ana , Stathopoulou Eleni , Munoz-Garcia Felix
Published: March 2021

This paper examines green alliances between environmental groups (EGs) and polluting firms, which have become more common in the last decades, and analyzes how they affect policy design. We first show that the activities of regulators and EGs are strategic substitutes, giving rise to free-riding incentives on both agents. Nonetheless, the presence of the EG yields smaller welfare benefits when firms are subject to regulation than when they are not. In addition, the introduction of environmental policy yields large welfare gains when the EG is absent but small benefits when the EG is already present.
Evaluation of the surface dose for total body irradiation (TBI) technique with parallel-opposed anterior posterior geometry
Authors: Elham Hoseinnezhadzarghani , Ghazale Geraily , Sarmadi Sarvin
Published: March 2021

Aim:

Total body irradiation (TBI) is an external radiotherapy technique in which the whole body including the superficial regions is required to receive the therapeutic dose. The purpose of this study is to evaluate the received surface dose during TBI technique.

Methods and materials:

The anterior/posterior (AP/PA) TBI was implemented with 18-MV photon beam at 312-cm treatment distance for human-like phantom. The GAFCHROMIC-EBT3 films were used for superficial dose measurements.

Results and discussion:

The percentage of surface-absorbed dose relative to the prescription point for 8 points of measurements was between 102·78–121·48% and 104·51–127·43% at 5 and 10 mm depth, respectively. In the chest wall region due to the presence of lung blocks, the absorbed dose was below the acceptable level, so an electron boost was required to increase the chest wall absorbed dose.

Conclusions:

According to the results, the implemented technique was able to deliver sufficient dose to the shallow surface of phantom’s body.
