The hierarchical SMAA-PROMETHEE method applied to assess the sustainability of European cities
Authors: Corrente Salvatore , Greco Salvatore , Leonardi Floriana , Słowiński Roman
Published: April 2021

Measuring the level of sustainability taking into account many contributing aspects is a challenge. In this paper, we apply a multiple criteria decision aiding framework, namely, the hierarchical-SMAA-PROMETHEE method, to assess the environmental, social, and economic sustainability of 20 European cities in the period going from 2012 to 2015. The application of the method is innovative for the following reasons: (i) it permits to study the sustainability of the mentioned cities not only comprehensively but also considering separately particular macro-criteria, providing in this way more specific information on their weak and strong points; (ii) the use of PROMETHEE and, in particular, of PROMETHEE II, avoids the compensation between different and heterogeneous criteria, that is arbitrarily assumed in value function aggregation models; finally, (iii) thanks to the application of the Stochastic Multicriteria Acceptability Analysis, the method provides more robust recommendations than a method based on a single instance of the considered preference model compatible with few preference information items provided by the Decision Maker.

Published: April 2021

Annual maximum lake surface temperature influences ecosystem structure and function and, in particular, the rates of metabolic activities, species survival and biogeography. Here, we evaluated 50 years of observational data, from 1966 to 2015, for ten European lakes to quantify changes in the annual maximum surface temperature and the duration above a potentially critical temperature of 20 °C. Our results show that annual maximum lake surface temperature has increased at an average rate of +0.58 °C decade−1 (95% confidence interval 0.18), which is similar to the observed increase in annual maximum air temperature of +0.42 °C decade−1 (95% confidence interval 0.28) over the same period. Increments in lake maximum temperature among the ten lakes range from +0.1 in the west to +1.9 °C decade−1 in the east. Absolute maximum lake surface water temperatures were reached in Wörthersee, 27.5 °C, and Neusiedler See, 31.7 °C. Periods exceeding a critical temperature of 20 °C each year became two to six times longer than the respective average (6 to 93). The depth at which water temperature exceeded 20 °C increased from less than 1 to more than 6 m in Mondsee, Austria, over the 50 years studied. As a consequence, the habitable environment became increasingly restricted for many organisms that are adapted to historic conditions.

Published: April 2021

Purpose

To study the effect of stimulus size and temporal frequency on the relative contribution of luminance and L-/M-cone opponent signals in the ERG.

Methods

In four healthy, color normal subjects, ERG responses to heterochromatic stimuli with sinusoidal, counter-phase modulation of red and green LEDs were measured. By inverse variation of red and green contrasts, we varied luminance contrast while keeping L-/M-cone opponent chromatic contrast constant. The first harmonic components in the full field ERGs are independent of stimulus contrast at 12 Hz, while responses to 36 Hz stimuli vary, reaching a minimum close to isoluminance. It was assumed that ERG responses reflect L-/M-cone opponency at 12 Hz and luminance at 36 Hz. In this study, we modeled the influence of temporal frequency on the relative contribution of these mechanisms at intermediate frequencies, measured the influence of stimulus size on model parameters, and analyzed the second harmonic component at 12 Hz.

Results

The responses at all frequencies and stimulus sizes could be described by a linear vector addition of luminance and L-/M-cone opponent reflecting ERGs. The contribution of the luminance mechanism increased with increasing temporal frequency and with increasing stimulus size, whereas the gain of the L-/M-cone opponent mechanism was independent of stimulus size and was larger at lower temporal frequencies. Thus, the luminance mechanism dominated at lower temporal frequencies with large stimuli. At 12 Hz, the second harmonic component reflected the luminance mechanism.

Conclusions

The ERGs to heterochromatic stimuli can be fully described in terms of linear combinations of responses in the (magnocellular) luminance and the (parvocellular) L-/M-opponent retino-geniculate pathways. The non-invasive study of these pathways in human subjects may have implications for basic research and for clinical research.
Droplet impact onto a spring-supported plate: analysis and simulations
Authors: Negus Michael J. , Moore Madeleine R. , Oliver James M. , Cimpeanu Radu
Published: April 2021

The high-speed impact of a droplet onto a flexible substrate is a highly non-linear process of practical importance, which poses formidable modelling challenges in the context of fluid–structure interaction. We present two approaches aimed at investigating the canonical system of a droplet impacting onto a rigid plate supported by a spring and a dashpot: matched asymptotic expansions and direct numerical simulation (DNS). In the former, we derive a generalisation of inviscid Wagner theory to approximate the flow behaviour during the early stages of the impact. In the latter, we perform detailed DNS designed to validate the analytical framework, as well as provide insight into later times beyond the reach of the proposed analytical model. Drawing from both methods, we observe the strong influence that the mass of the plate, resistance of the dashpot, and stiffness of the spring have on the motion of the solid, which undergo forced damped oscillations. Furthermore, we examine how the plate motion affects the dynamics of the droplet, predominantly through altering its internal hydrodynamic pressure distribution. We build on the interplay between these techniques, demonstrating that a hybrid approach leads to improved model and computational development, as well as result interpretation, across multiple length and time scales.
Particle movement in a boundary layer
Authors: Jolley Ellen M. , Palmer Ryan A. , Smith Frank T.
Published: April 2021

The study here is concerned with a thin solid body passing through a boundary layer or channel flow and interacting with the flow. Relevant new features from modelling, analysis and computation are presented along with comparisons. Three scenarios of such fluid-body interactive evolution in two-dimensional settings are considered in turn, namely a long body translating upstream or downstream, a long body with little or no translation and a short body with or without translation. The main progress and findings concern predictions of the time taken by the body to traverse the flow and impact upon the underlying wall, the delicate behaviour at the onset of impact, the dependence on parameters such as the initial conditions and the mass and shape of the body, and the influence of streamwise translation of the body in the surrounding fluid flow.
Integrative hormone and transcriptome analysis underline the role of abscisic acid in seed shattering of weedy rice
Authors: Lang Hong , He Yuting , Li Fengcheng , Ma Dianrong , Sun Jian
Published: April 2021

Weedy rice is one of the most severe weeds in paddy fields, characterized by its high degree of seed shattering. Abscisic acid (ABA) serves as an abscission-accelerating signal and plays a critical role during abscission. However, mechanisms that link ABA and seed shattering remain elusive. In this study, WR04-6 (shattering) and SN9816 (non-shattering) were used to investigate the expression levels of genes involved in ABA biosynthesis and to determine the levels of ABA in tissues collected from the abscission zone (AZ) and the spikelet. ABA content in WR04-6, particularly in AZ, was significantly higher than in SN9816, significantly increasing prior to abscission. RNA-Sequencing and further expression analyses showed that the expression of OsNCED, the key gene involved in ABA biosynthesis, coincided with the increase of ABA content in the AZ and significantly increased during the seed shattering process. Additionally, the expression analysis of genes related to biosynthesis and metabolism of indole-3-acetic acid, gibberellin acid, and ethylene showed the greatest fold-change. Phytohormone levels associated with ABA co-expression-prediction revealed a potential signal transduction network among plant hormones involved in the regulation of seed abscission. Taken together, data presented in this study suggest that ABA contributes to seed shattering and transiently cooperates with other hormones, triggering a hormone imbalance that leads to the downstream activation of the AZ.
How theoretical is your (historical) syntax? Towards a typology of Verb-Third in Early Old High German
Authors: Catasso Nicholas
Published: April 2021

Verb-Third (V3) constructions, i.e. root clauses displaying more than one element in their prefield, have been attested throughout the history of German. In this paper, I discuss some methodological issues related to the investigation of this structure in Early Old High German (EOHG, eighth to ninth century). In this language stage, the linear syntax of matrix clauses is very unstable—mainly due to the not-yet complete systematization of the V2/verb-final distinction and to the considerable amount of extraposition in main clauses—which makes the detection of this construction in the available texts particularly challenging. Moreover, little substantial and reliable prose data are extant for this period. In order to get a realistic picture of the distribution of the phenomenon at stake in EOHG, it is therefore necessary to evaluate the data by means of diagnostic tests for verb movement and only consider those cases in which the verb is unambiguously located in C and the preverbal area hosts multiple (head or non-head) elements. I will show that: (1) some of the patterns that are usually assumed to be good candidates for the category of V3 in the relevant literature are never attested in the diagnostic dataset; (2) a typology consisting of five non-correlative and three correlative diagnostic V3 constructions can be identified on the basis of an approach based on replicable methods; (3) some of these patterns display historical continuity; (4) non-prose texts are inadequate for syntactic investigations.
Land use and climate change affects butterfly diversity across northern Austria
Authors: Habel Jan Christian , Teucher Mike , Gros Patrick , Schmitt Thomas , Ulrich Werner
Published: April 2021

Context

Biodiversity is severely decreasing at a global scale since several decades. There are significant changes in species community compositions, reductions of species richness and abundances of arthropods, as well as of arthropod biomass. Land use intensification and climate change are assumed to be main drivers causing biodiversity change and loss. However, proximate effects of land use, landscape configuration, topography and climate on species richness and species community composition were only rarely analysed.

Objective

We study the effects of current land cover, landscape structures and climate on butterfly and burnet moth species diversity and community composition across northern Austria (i.e. the federal state of Salzburg).

Methods

We compiled observation data of butterflies and burnet moths for the past 40 years. We divided faunal data, land cover data and data on climate into 5 × 5 km2grid cells. We classified all lepidopterans assessed into groups according to their distribution, behaviour, ecology and life-history.

Results

We found higher species richness and temporal community shifts in higher elevations, and where topographic heterogeneity is high. Habitat connectivity has a positive impact on ecologically specialised, sedentary, and endangered species. Mean temperature and precipitation positively influenced species richness.

Conclusions

Both, land-use and climate strongly shape biodiversity structures. In particular, landscape heterogeneity promotes the diversity of ecological niches, which subsequently accelerates species diversity, including specialist species. Agricultural intensification in higher elevations and at steep slopes is more difficult and therefore less attractive, and thus the level of biodiversity is still high. In addition, climate warming might lead to the accumulation of species in higher elevations. Our study further underlines the relevance of habitat conservation at lower elevations, where not all habitat types are conserved sufficiently.

Bradley Conditionals and Dynamic Choice
Authors: Huttegger Simon M. , Rothfus Gerard J.
Published: April 2021

One of the main contributions of Richard Bradley’s book is an elegant extension of Jeffrey’s Logic of Decision that countenances the evaluation of conditional prospects. This extension offers a promising new setting in which to model dynamic choice. In Bradley’s framework, plans can be understood as conditionals of an appropriate sort, while dynamic consistency can be viewed as providing a constraint on the evaluation of conditionals across time. In this paper, we study connections between planning conditionals and dynamic consistency.
SMA micro-hand implemented in small robot for generating gestures
Authors: Takumi Ishikawa , Sumito Nagasawa
Published: April 2021

Research on robots that can be used for communication with humans has become popular in recent years. Communication robots should ideally be as small as an infant in order to reduce the user’s feeling of threat. In addition, non-verbal communication (such as gestures) is also important in facilitating smooth interactions between humans and robots. There are currently a few communication robots that are small sized and can generate hand gestures. In this paper, we propose a small robot hand, which is optimized for gesture communication by using a shape memory alloy (SMA). The SMA employed is a Ti–Ni alloy, which is used as an actuator. The SMA shrinks when it transforms into the austenite phase at temperatures higher than the transformation temperature. When it is in the martensitic phase at a lower temperature, it is expanded by an external force. Each finger of the robot hand is driven by an individual SMA wire. The specifications of the small robot including the hand size, operation angles in each finger joint, response times and power consumption were determined according to the human finger and existing small communication robots. These required specifications have been fulfilled by carefully designing the geometry and heating/cooling power control. A questionnaire-based survey was also conducted with a robot hand. The five-finger hand was successfully shown to generate recognizable symbolic gestures.
The effect of hemoadsorption on rivaroxaban blood plasma concentration in emergency cardiac surgery
Authors: Krüger Bernard , Renner Tobias , Van Hemelrijck Mathias , Sromicki Juri , Ouda Ahmed , Mestres Carlos - A.
Published: April 2021

Hemoadsorption was used in a 59-year-old patient with an acute type A aortic dissection, who was on rivaroxaban and dual antiplatelet therapy with clopidogrel and acetylsalicylic acid. Our aim was to expeditiously remove rivaroxaban preoperatively. After 8 h of hemoadsorption, the rivaroxaban blood plasma concentration (RBPC) did not decrease below 42.1 μg/l. Intraoperatively, hemoadsorption was repeated during extracorporeal circulation. Sixteen hours after surgery and a total of 13 h of hemoadsorption, the RBPC was 40.1 μg/l. Thereafter, the RBPC spontaneously decreased to 24.7 μg/l within 14 h. In our patient, hemoadsorption may have enhanced rivaroxaban removal at higher RBPC (cutoff value 40–50 μg/l). At lower RBPC, the removal of rivaroxaban may depend solely on the natural drug elimination process. The evolution of the RBPC under hemoadsorption in vivo warrants a thorough investigation. Further clinical studies are required to assess the effectiveness and limitations of hemoadsorption to preclude a fatal bleeding event in patients with rivaroxaban in need of major emergency surgery.

Soft corals are well-known as excellent sources of marine-derived natural products. Among them, members of the genera Sarcophyton, Sinularia, and Lobophytum are especially attractive targets for marine natural product research. In this review, we reported the marine-derived natural products called cembranoids isolated from soft corals, including the genera Sarcophyton, Sinularia, and Lobophytum. Here, we reviewed 72 reports published between 2016 and 2020, comprising 360 compounds, of which 260 are new compounds and 100 are previously known compounds with newly recognized activities. The novelty of the organic molecules and their relevant biological activities, delivered by the year of publication, are presented. Among the genera presented in this report, Sarcophyton spp. produce the most cembranoid diterpenes; thus, they are considered as the most important soft corals for marine natural product research. Cembranoids display diverse biological activities, including anti-cancer, anti-bacterial, and anti-inflammatory. As cembranoids have been credited with a broad range of biological activities, they present a huge potential for the development of various drugs with potential health and ecological benefits.

Comparing online travel review platforms as destination image information agents
Authors: Guo Xinxin , Pesonen Juho , Komppula Raija
Published: April 2021

Online travel reviews have been extensively used as an important data source in tourism research. Typically, data for online travel review research is collected only from one platform. However, drawing definite conclusions based on single platform analyses may thus produce biases and lead to erroneous conclusions and decisions. Therefore, this research verifies whether or not there are discrepancies and commonalities between different travel review platforms. In this study, five native Chinese travel review platforms were selected: Ctrip; Qyer; Mafengwo; Tuniu; and Qunar. Using a mixed content analysis method, the destination image of Finland was extracted from 10,197 travel reviews in Simplified Chinese as the destination image is a popular topic in online review research. Results show Finland’s destination image representation varies between Chinese travel review platforms. This discrepancy is especially prominent in the dimension of functional and mixed functional-psychological destination attributes. Significant theoretical contributions and managerial implications for the analysis of online travel reviews and destination image research are discussed.
Adolescent Mother Maltreatment Perpetrators’ Past Experiences with Child Protective Services
Authors: Shusterman Gila R. , Nunez Juan J. , Fettig Nicole B. , Kebede Bethel K.
Published: April 2021

The experience of childhood maltreatment is associated with pregnancy during adolescence and increased risk for maltreating one’s own child or children. However, adolescent mothers who have been identified by child protective services (CPS) both as perpetrators and alleged victims carry a unique burden of trauma and are seldom the focus of retrospective studies. This study examines the extent to which adolescent mother perpetrators have prior experience with CPS as alleged victims and how their current perpetrator characteristics are associated with their prior CPS experience. We constructed a study sample of adolescent mother perpetrators reported to the National Child Abuse and Neglect Data System (NCANDS) by 27 states for federal fiscal years (FFYs) 2016–2018 (N = 8205) and determined whether they had any prior CPS experience as alleged victims since 2005. Characteristics of the participants as both perpetrators and alleged victims were examined, and associations between these were analyzed using odds ratios. Nearly two-thirds (62%) of adolescent mother perpetrators had prior experience with CPS. Analyses revealed significant associations of prior CPS experiences and perpetrator age, race, and connection with additional perpetrators. The types of maltreatment allegations that adolescent mothers experienced as children were significantly associated with the type of maltreatment they perpetrated. Key conclusions highlight the importance in understanding the link between childhood CPS experience and later maltreatment perpetration by adolescent mothers which will in turn help target prevention services to break the cycle of intergenerational maltreatment. Limitations and future research directions are discussed.
How far are the metropolitan areas in Brazil from achieving the sustainable development goals? An analysis based on SDG dashboards
Authors: Silva Martinelli Fernanda , Lindner André
Published: April 2021

Cities comprise the major challenges for sustainable development and are key contributors to sustainability indicators in a country. However, research assessing sustainability performance often focuses on the national level, overlooking the role of urban areas. To evaluate the city performance toward a sustainable pathway, this paper proposes the sustainable development goals (SDGs) Dashboard for Brazilian Cities, with a comprehensive assessment of their specific challenges based on the SDG Index methodology (UNSDSN). The 19 country’s most populous metropolitan areas (MAs) were considered, which comprises 41% of the population. From 17 SDGs, this paper evaluates 8 of the 12 SDGs defined with a social and environmental profile, covering data from 34 indicators. Results show that all MAs have a long way to achieve most of the analyzed SDGs, especially regarding inequalities (income and gender). Inequalities of performance are also observed among the country into a clear north–south distinction, where the GDP richest regions perform better toward the SDGs. However, cities with a good performance in education (SDG 4) are less unequal (SDG 10), indicating interrelations between SDGs. Despite the inequalities, MAs are doing relatively well in reducing poverty (SDG 1) and providing water and sanitation (SDG 6). The SDG Dashboards for Brazilian Cities can be used as a framework for action and help urban leaders address implementation challenges across cities.

Published: April 2021

Crime Prevention: Principles, Perspectives and Practices introduces readers to the theory and practice of crime prevention. Now in its third edition, this book argues for a combination of social and situational/environmental crime prevention strategies as more effective alternatives to policing, criminal justice and 'law and order' approaches. Contending that the principles of prevention can be applied to persistent crime problems such as alcohol-related violence and family and domestic violence, the book explores the prevention of other broad societal harms including terrorism, cybercrime and threats to the environment. The book features useful pedagogy such as case studies, discussion questions and extension topics, as well as new chapters on environmental crime and counter-terrorism. Written by a team of experts in the field of criminology, Crime Prevention remains an authoritative introduction to crime prevention in Australia, and is an invaluable resource for criminology students.
The Second Cold War
Authors: Donaghy Aaron
Published: April 2021

Towards the end of the Cold War, the last great struggle between the United States and the Soviet Union marked the end of détente, and escalated into the most dangerous phase of the conflict since the Cuban Missile Crisis. Aaron Donaghy examines the complex history of America's largest peacetime military buildup, which was in turn challenged by the largest peacetime peace movement. Focusing on the critical period between 1977 and 1985, Donaghy shows how domestic politics shaped dramatic foreign policy reversals by Presidents Jimmy Carter and Ronald Reagan. He explains why the Cold War intensified so quickly and how - contrary to all expectations - US-Soviet relations were repaired. Drawing on recently declassified archival material, The Second Cold War traces how each administration evolved in response to crises and events at home and abroad. This compelling and controversial account challenges the accepted notion of how the end of the Cold War began.
Ed Ruscha, Streets of Los Angeles project: developing collaborations to support digital art history
Authors: Pugh Emily , Sallabedra Megan
Published: April 2021

For the past four years, the team working on the “Ed Ruscha, Streets of Los Angeles” project at the Getty Research Institute has worked to establish a framework for leveraging the benefits of collaboration and conversation between groups of people who work in different areas of expertise and communities of practice. Facilitating sustained conversations among art historians, art librarians, and technical specialists has proved a successful framework of mutual consultation between Getty staff and external collaborators. These conversations helped external collaborators better understand the kinds of metadata generated through the archival process and how it might be useful for investigating their particular research questions. In turn, Getty staff gained a better understanding of the kinds of metadata helpful to researchers, which helped determine our own priorities for this work. Moreover, new avenues of inquiry emerging from this collaborative project have outlined a path for articulating best practices in digital art history projects to come.
Systematic development of load-path dependent FLM-FRP lightweight structures
Authors: Voelkl Harald , Wartzack Sandro
Published: April 2021

Additive manufacturing offers a high degree of design freedom. When Design for Additive Manufacturing is conducted properly, lightweight potential can be exploited. This contribution introduces a novel design approach for the widespread fused layer modelling (FLM) technology when using orthotropic Fibre Reinforced Polymer filament. Its objective is to obtain stiff and strong load-path optimized FLM structures in a structured and algorithmic way. The approach therefore encompasses (1) build orientation optimization to consider weaker bonding between layers than intralayer; (2) topology optimization with orthotropic material properties to obtain favourable overall geometry and inner structure; (3) direct build path generation from optimized material orientation and alternatives to the direct generation and (4) simulation. The approach is demonstrated using a lift arm under multiple load cases and further demonstrator parts to show its general applicability. Lightweight potential of individual optimization steps and the influence of modifications contrasting general non-FLM-specific optimization are studied and discussed.
Ultra-processed food consumption in Barbados: evidence from a nationally representative, cross-sectional study
Authors: Harris Rachel M. , Rose Angela M. C. , Soares-Wynter Suzanne , Unwin Nigel
Published: April 2021

Our objective was to describe, for the first time in an English-speaking Caribbean country, the contribution of ultra-processed foods (UPFs) to nutrients linked to non-communicable disease. Using a cross-sectional study design, dietary data were collected from two non-consecutive 24-h dietary recalls. Recorded food items were then classified according to their degree of processing by the NOVA system. The present study took place in Barbados (2012–13). A representative population-based sample of 364 adult Barbadians (161 males and 203 females) aged 25–64 years participated in the study. UPFs represented 40⋅5 % (838 kcal/d; 95 % CI 791, 885) of mean energy intake. Sugar-sweetened beverages made the largest contribution to energy within the UPF category. Younger persons (25–44 years) consumed a significantly higher proportion of calories from UPF (NOVA group 4) compared with older persons (45–64 years). The mean energy shares of UPF ranged from 22⋅0 to 58⋅9 % for those in the lowest tertile to highest tertile. Within each tertile, the energy contribution was significantly higher in the younger age group (25–44 years) compared with the older (45–64 years). One-quarter of persons consume ≥50 % of their daily calories from UPF, this being significantly higher in younger persons. The ultra-processed diet fraction contained about six times the mean of free sugars and about 0⋅8 times the dietary fibre of the non-ultra-processed fraction (NOVA groups 1–3). Targeted interventions to decrease the consumption of UPF especially in younger persons is thus of high priority to improve the diet quality of Barbadians.
HD 76920 b pinned down: A detailed analysis of the most eccentric planetary system around an evolved star

Published: April 2021

We present 63 new multi-site radial velocity (RV) measurements of the K1III giant HD 76920, which was recently reported to host the most eccentric planet known to orbit an evolved star. We focused our observational efforts on the time around the predicted periastron passage and achieved near-continuous phase coverage of the corresponding RV peak. By combining our RV measurements from four different instruments with previously published ones, we confirm the highly eccentric nature of the system and find an even higher eccentricity of

$e=0.8782 \pm 0.0025$

, an orbital period of

$415.891^{+0.043}_{-0.039}\,\textrm{d}$

, and a minimum mass of

$3.13^{+0.41}_{-0.43}\,\textrm{M}_{\textrm{J}}$

for the planet. The uncertainties in the orbital elements are greatly reduced, especially for the period and eccentricity. We also performed a detailed spectroscopic analysis to derive atmospheric stellar parameters, and thus the fundamental stellar parameters (

$M_*, R_*, L_*$

), taking into account the parallax from Gaia DR2, and independently determined the stellar mass and radius using asteroseismology. Intriguingly, at periastron, the planet comes to within 2.4 stellar radii of its host star’s surface. However, we find that the planet is not currently experiencing any significant orbital decay and will not be engulfed by the stellar envelope for at least another 50–80 Myr. Finally, while we calculate a relatively high transit probability of 16%, we did not detect a transit in the TESS photometry.
Computing the shape gradient of stellarator coil complexity with respect to the plasma boundary
Authors: Carlton-Jones Arthur , Paul Elizabeth J. , Dorland William
Published: April 2021

Coil complexity is a critical consideration in stellarator design. The traditional two-step optimization approach, in which the plasma boundary is optimized for physics properties and the coils are subsequently optimized to be consistent with this boundary, can result in plasma shapes which cannot be produced with sufficiently simple coils. To address this challenge, we propose a method to incorporate considerations of coil complexity in the optimization of the plasma boundary. Coil complexity metrics are computed from the current potential solution obtained with the REGCOIL code (Landreman,Nucl. Fusion, vol. 57, 2017, 046003). While such metrics have previously been included in derivative-free fixed-boundary optimization (Drevlaket al.,Nucl. Fusion, vol. 59, 2018, 016010), we compute the local sensitivity of these metrics with respect to perturbations of the plasma boundary using the shape gradient (Landreman & Paul,Nucl. Fusion, vol. 58, 2018, 076023). We extend REGCOIL to compute derivatives of these metrics with respect to parameters describing the plasma boundary. In keeping with previous research on winding surface optimization (Paulet al.,Nucl. Fusion, vol. 58, 2018, 076015), the shape derivatives are computed with a discrete adjoint method. In contrast with the previous work, derivatives are computed with respect to the plasma surface parameters rather than the winding surface parameters. To further reduce the resolution required to compute the shape gradient, we present a more efficient representation of the plasma surface which uses a single Fourier series to describe the radial distance from a coordinate axis and a spectrally condensed poloidal angle. This representation is advantageous over the standard cylindrical representation used in the VMEC code (Hirshman & Whitson,Phys. Fluids, vol. 26, 1983, pp. 3553–3568), as it provides a uniquely defined poloidal angle, eliminating a null space in the optimization of the plasma surface. In comparison with previous spectral condensation methods (Hirshman & Breslau,Phys. Plasmas, vol. 5, 1998, p. 2664), the modified poloidal angle is obtained algebraically rather than through the solution of a nonlinear optimization problem. The resulting shape gradient highlights features of the plasma boundary that are consistent with simple coils and can be used to couple coil and fixed-boundary optimization.
Estimating the conservation cost of the projected new international Lisbon airport for migratory shorebirds of the Tagus estuary, Portugal

Published: April 2021

The increasing pressure of anthropogenic development in areas with high natural value poses a huge challenge for wildlife conservation worldwide. The Tagus estuary in southern Portugal is among the most important wetlands for migratory shorebirds in the East Atlantic Flyway (EAF). However, in 2020 the Portuguese government approved the construction of the new Lisbon international airport at the heart of the Tagus estuary. Intense aircraft traffic, flying at low altitudes during both approach and take-off, is expected to cross the estuary, overlapping to a great extent the important intertidal foraging areas. Here, we aim to quantify the potential loss of conservation value of the intertidal areas of the Tagus estuary for shorebirds resulting from the disturbance (noise) caused by overflying aircraft. Using a comprehensive dataset of wintering shorebird abundance and distribution in the whole intertidal estuarine area we first identified priority areas for conservation using a spatial prioritization approach. We then performed a replacement cost analysis by excluding the areas likely to become unsuitable or severely underused by birds due to intense air traffic noise. Our results suggest that the implementation of the new Lisbon airport may lead to a loss of up to 30% of the conservation value of the Tagus estuary in terms of intertidal feeding areas of wintering birds alone. The global impact will likely be greater when effects on supratidal roosts, as well as on passage birds, are also considered. The Tagus estuary, which is internationally important for six of the 10 species included in our analysis, is just one of a network of already depleted sites along the EAF. Thus, negative impacts on bird populations on the Tagus estuary will have repercussions and undermine conservation efforts elsewhere. The plight of shorebirds at the Tagus estuary is thus a matter of international conservation concern.
Evaluation of set-up errors and estimation of set-up margin during external beam radiation therapy of prostate cancer using electronic portal imaging device (EPID)

Aim:

In radiation therapy, accurate dose distribution in target volume requires accurate treatment setup. The set-up errors are unwanted and inherent in the treatment process. By achieving these errors, a set-up margin (SM) of clinical target volume (CTV) to planning target volume (PTV) can be determined. In the current study, systematic and random set-up errors that occurred during prostate cancer radiotherapy were measured by an electronic portal imaging device (EPID). The obtained values were used to propose the optimum CTV-to-PTV margin in prostate cancer radiotherapy.

Materials and methods:

A total of 21 patients with prostate cancer treated with external beam radiation therapy (EBRT) participated in this study. A total of 280 portal images were acquired during 12 months. Gross, population systematic (Σ) and random (σ) errors were obtained based on the portal images in Anterior–Posterior (AP), Medio-Lateral (ML) and Superior–Inferior (SI) directions. The SM of CTV to PTV were then calculated and compared by using the formulas presented by the International Commission on Radiation Units and Measurements (ICRU) 62, Stroom and Heijmen and Van Herk et al.

Results:

The findings showed that the population systematic errors during prostate cancer radiotherapy in AP, ML and SI directions were 1·40, 1·95 and 1·94 mm, respectively. The population random errors in AP, ML and SI directions were 2·09, 1·85 and 2·29 mm, respectively. The SM of CTV to PTV calculated in accordance with the formula of ICRU 62 in AP, ML and SI directions were 2·51, 2·68 and 3·00 mm, respectively. And according to Stroom and Heijmen, formula were 4·23, 5·19 and 5·48 mm, respectively. And Van Herk et al. formula were 4·96, 6·17 and 6·45 mm, respectively.

Findings:

The SM of CTV to PTV in all directions, based on the formulas of ICRU 62, Stroom and Heijmen and van Herk et al., were equal to 2·73, 4·98 and 5·86 mm, respectively; these values were obtained by averaging the margins in all directions.

Aim:

This study evaluates a healthcare walk-in centre in an immigrant-dense area from the perspective of Swedish-born patients.

Background:

The studied healthcare centre started a walk-in centre to increase healthcare accessibility for immigrants. This form of care is not primarily for Swedish-born patients although everyone is welcome. For this reason, it is important to evaluate the walk-in centre from different perspectives: the healthcare workers, the immigrant patients, and in this study focusing on the Swedish-born patients.

Method:

This qualitative exploratory study used content analysis to analyse data collected from semi-structured interviews. Semi-structured interviews were held with 12 purposively sampled Swedish-born patients visiting a healthcare centre in Sweden.

Findings:

Most informants characterised the care they received as professional and timely and noted that accessibility was the main reason they sought care at the walk-in centre. In addition, they noted that being able to seek care on the day they want creates a feeling of security. However, Swedish-born informants seemed to prefer a traditional healthcare centre, although they viewed the walk-in centre as legitimate because everyone has access to it.

Conclusion:

As the walk-in centre was perceived as having good accessibility, participants experienced that they could easily receive help for minor health problems. However, they also identified several ways the walk-in centre could be improved. For example, some participants preferred to remain outside while awaiting their turn to see a healthcare provider and wanted immigrant patients to leave their relatives at home when possible to minimise the risk of spreading infection. In addition, some participants thought a triage system could be implemented so that more severe cases could advance more quickly in the queue. The homogeneous sample of informants raises questions about whether this healthcare model is indeed accessible to everyone.
“Their New Jerusalem”: Representations of Jewish Immigrants in the American Popular Press, 1880–1903
Authors: Varat Deborah
Published: April 2021

Millions of immigrants arrived in the United States during the Gilded Age, drastically altering the ethnic character of the American citizenry. This dramatic social change was met with mixed reactions from the native-born population that were vividly communicated in the popular press. Cartoonists for newspapers and magazines across the country developed a language of caricature to identify and distinguish among ethnic groups and mocked new arrivals in imagery that ranged from mild to malicious. One might assume that the masses of Eastern European Jews flooding into the country (poor, Yiddish-speaking, shtetl-bred) would have been singled out for anti-Semitic attack, just as they were in Europe at the time. However, Jews were not the primary victims of visual insults in America, nor were the Jewish caricatures wholly negative. Further, the broader scope of popular imagery, which, in addition to cartoons, includes a plethora of illustrations as well as photographs, presents a generally positive attitude toward Jewish immigrants. This attitude aligned with political rhetoric, literature, newspaper editorials, and financial opportunity. This article will propose a better alignment of the visual evidence with the scholarly understanding of the essentially providential experience of Jews in America during this period.
From Native Sovereignty to an Oilman’s State: Land, Race, and Petroleum in Indian Territory and Oklahoma
Authors: Boxell Mark
Published: April 2021

During the first two decades of the twentieth century, Indian Territory and the State of Oklahoma experienced one of the world’s largest petroleum booms, with much of the oil extracted from the territory and state produced on land owned by Indigenous, Black, and mixed-race peoples. White settlers, backed by governing institutions and cultures rooted in settler colonialism, anti-Black racism, and anti-monopolism, struggled to seize control of oil-rich land amid the allotment of Native-owned property. These latter elements insisted that non-whites could not grasp the value of petroleum nor be trusted with the control of such a vital resource, especially in the shadow of ever-looming oil monopolies. Settlers and wildcat prospectors built a white-supremacist oil-field politics that elevated the rights of small-scale, proprietary "independent" oilmen and worked to ensure that the latter controlled flows of crude vis-à-vis non-white property holders and “outside” corporations. For white settlers in Indian Territory and Oklahoma, oil rose to the top of collective imaginaries about race, property, and wealth, encouraging the creation of both legal and often violent extralegal strategies for dispossessing unworthy landowners of their hydrocarbon inheritance.
Publish the Picture at Your Peril: Visual Ideas and the Commercial Apparatus of Life Magazine
Authors: Schwartz Joshua S.
Published: April 2021

In the early years of the twentieth century, Life magazine had only approximately one hundred thousand subscribers, yet its illustrated images (like the Gibson Girl) significantly influenced fashion trends and social behaviors nationally. Its outsized influence can be explained by examining the magazine’s business practices, particularly the novel ways in which it treated and conceptualized its images as intellectual property. While other magazines relied on their circulation and advertising revenue to attain profitability, Life used its page space to sell not only ads, but also its own creative components—principally illustrations—to manufacturers of consumer goods, advertisers, and consumers themselves. In so doing, Life’s publishers relied on a developing legal conception of intellectual property and copyright, one that was not always amenable to their designs. By looking at a quasi-litigious disagreement in which a candy manufacturing company attempted to copy one of the magazine’s images, this article explores the mechanisms behind the commodification and distribution of mass-circulated images.
It’s All About Power

Abstract. The present research was aimed at providing a German version of the Personal Sense of Power Scale (GPSPS; Anderson et al., 2012 ) and testing its psychometric properties. A personal sense of power describes the perception of one’s ability to influence others. Probably every human relationship can be characterized by differences in power, which means that the measurement of experienced power is highly relevant. The availability of appropriate measures in different languages will help improve research and cross-cultural comparisons. Five studies were conducted. Internal consistency was high across all studies. Stability across 6 and 12 weeks was also high. A good fit was observed for a 6-item unidimensional version. Correlations with a variety of psychological and sociodemographic variables were in the expected directions, supporting nomological and criterion validity (Study 1). Measurement invariance across gender was demonstrated. In support of construct validity, a clinical sample scored significantly lower than others. Finally, two studies showed the sensitivity of a state version of the scale. We encourage researchers to use this scale as a reliable and valid instrument for assessing trait and state power.
