Prediction of the VDT Worker's Headache Using Convolutional Neural Network with Class Activation Mapping
Authors: Sharara Elsayed A. , Tsuji Akinori , Karungaru Stephen , Terada Kenji
Published: September 2020

A headache and drowsiness are the most common symptoms of fatigue caused by a long duration of work using a visual display terminal (VDT). A sign of the headache generally involves placing a hand on the head, eyes, nose, or face. The recognition of these gestures is a challenging problem due to the difficulty in similar skin color of hands and face. In this paper, a method for classifying six hand over face poses, which can identify the signs of headache for the VDT workers is presented. In the proposed method, a deep learning based on a convolutional neural network (CNN) for the classification of the hand poses is applied. In addition, a class activation map (CAM) to visualize the prediction of the classification network for localization of the hand over face poses was implemented. From the experimental results, the hand poses as the signs of frontal, and unilateral headaches without the classification overfitting and data biasing errors were successfully classified. Our proposed method has achieved high accuracy recognition ratio of 98.5% for classification of the hand over face poses as the prediction of headaches. © 2020 Institute of Electrical Engineers of Japan.

Adsorptive removal of heavy metals from industrial effluents using cow dung as the biosorbent: Kinetic and isotherm modeling
Authors: Saraswat Sushil Kumar , Demir Muslum , Gosu Vijayalakshmi
Published: September 2020

This article investigated an eco‐friendly technique for the removal of heavy metals using biosorbent derived from cow dung. Heavy metals bearing wastewater were collected from a common effluent treatment plant located at Sangariya, Jodhpur (Rajasthan, India) to evaluate the removal efficiency of synthesized cow dung–activated carbon. The prepared activated carbon materials have a high surface area in the range of 948–1072 m2/g and also have significant quantities of micropore and mesopore volumes. Furthermore, pore diameters were in the range of 2.24–2.33 nm. Surface morphology was improved after being treated with NaOH. The adsorbent material was found to be an efficient medium for the removal of Cr(VI) and Cd(II). The results revealed that more than 95.6% of Cr(VI) and 66.88% of Cd(II) were achieved at the optimized condition of pH12.0, initial concentration of heavy metals 10 mg/L, 300 min of contact time, and the dose of 0.2 g/L, whereas only 16.3% removal efficiency was observed for Ni(II). Equilibrium data have been analyzed by Langmuir, Freundlich, Temkin, and Redlich and Peterson (R–P) isotherm models with the help of nonlinear regression analysis. Experimental data were best fitted for Freundlich and R–P isotherms.
The evolution of Kraepelin's nosological principles
Authors: Heckers Stephan , Kendler Kenneth S.
Published: September 2020

Emil Kraepelin developed a new psychiatric nosology in the eight editions of his textbook. Previous papers have explored his construction of particular diagnoses, including dementia praecox and manic‐depressive insanity. Here we are providing a close reading of his introductory textbook chapter, that presents his general principles of nosology. We identify three phases: 1) editions 1‐4, in which he describes nosological principles in search of data; 2) editions 5‐7, in which he declares the mature version of his nosological principles and develops new disease categories; 3) edition 8, in which he qualifies his nosological claims and allows for greater differentiation of psychiatric disorders. We propose that Kraepelin's nosology is grounded in three principles. First, psychiatry, like other sciences, deals with natural phenomena. Second, mental states cannot be reduced to neural states, but science will progress and will, ultimately, reveal how nature creates abnormal mental states and behavior. Third, there is a hierarchy of validators of psychiatric diagnoses, with the careful study of clinical features (signs, symptoms and course) being more important than neuropathologic and etiological studies. These three principles emerged over the course of the eight editions of Kraepelin's textbook and were informed by his own research and by available scientific methods. His scientific views are still relevant today: they have generated and, at the same time, constrained our current psychiatric nosology.
Production of Chimeric Hepatitis B Virus Surface Antigens in Mammalian Cells
Authors: Dobrica Mihaela-Olivia , Lazar Catalin , Branza-Nichita Norica
Published: September 2020

The small (S) envelope protein of the Hepatitis B Virus (HBV), HBV-S, has the unique ability to self-assemble into highly immunogenic subviral particles (SVPs), in the absence of other viral factors, in eukaryotic cells, including those of nonhepatic origin. This feature is currently exploited for generation of SVPs exposing heterologous epitopes on their surface that can be used as vaccine candidates to target various diseases. Here, we describe a simple and robust method for production of such chimeric HBV-S protein-based SVPs in transiently transfected HEK293T cells and purification from cell supernatants by ultracentrifugation on sucrose cushion and sucrose step gradients. The SVPs obtained by this methodology have been successfully used in immunogenicity studies in animal models.
Climate Variability and Rural Livelihood Security: Impacts and Implications
Authors: Popoola Kehinde Olayinka , Jerneck Anne , Ajayi Sunday Adesola
Published: September 2020

In a typical Nigerian village, the majority of the population comprises old people who are mostly economically unproductive due to reduced or loss of physical strength brought about by ageing and ill health. Many of these rural old people still work, and do so outside the formal sector, and are particularly susceptible to the effects of climate variability and change. Few studies have reported on climate change and the rural aged and there is a research gap as regards rural elderly peoples’ perception of climate variability impact on them. Since little is known about their perception of climate variability impacts and implications on the rural aged especially in relation to their livelihood activities in Sub-Saharan Africa, this chapter therefore examined the impact of climate variability on the livelihood security of the rural aged in different ecological zones of Nigeria.

Both qualitative and quantitative methods were used for data collection. Qualitative data were obtained through interviews with four aged and four aged women selected purposively in each rural community and analyzed using Content Analysis Method. Quantitative data were obtained through structured questionnaire administered to an aged male and an aged female population available in selected houses (the aged are people 60 years and over in age) in selected rural communities in selected ecological zones of Nigeria. Where there was no combination of the two (aged men and aged women), either of the two was also sufficient.

It was discovered that the ageds’ experiences of climate variability impact relate to the prevailing climate variability characteristic of each ecological zones. The impact on their livelihood in these zones is seen in terms of livestock death, lack of pastures for herds, scarcity of water, pest invasion, delayed planting crop failure, need for irrigation, water logging, drowning of small animals, human and animal illness. This means that planning decisions related to climate change issues should take cognizance of the views of the aged populations especially of those residing in rural areas as they are the most affected by the impact.

In the above poem, trans* activist and spoken word poet Yolanda Aurora Bohm Ramirez (2018) both names the ways the lives of specific groups of people in Sweden are threatened by the increasing neo-Nazi violence and illuminates the response of the majoritarian population to these threats: their demands of silence where protest and criticism is made nearly impossible.
We Were Here, and We Still Are: Negotiations of Political Space Through Unsanctioned Art
Authors: Berg Linda , Lundgren Anna Sofia
Published: September 2020

In this chapter, we examine the work of the Sámi artist Anders Sunna and the Egyptian artist Bahia Shebab in order to address strategies of artistic criticism of the relations between states and their citizens. Both artists are protesting against contemporary processes relating to space, state and nation, and they express themselves in ways that are embedded in the aesthetics of unsanctioned street art. This expression constitutes an interesting form of politics, situated somewhere in-between, or alongside, party politics and the practices of civil society. Our aim is to describe and discuss what we see as specifically effective and dynamic themes in the chosen artwork—the use of space as object and methodology, and the production of iconic imageries within fantasies of protest. The stencils and spray paintings of Shehab and Sunna offer us keys to exploring efforts to artistically reveal and dismantle national and neocolonial power.
Rainbow Flag and Belongings/Disbelongings: Öckerö Pride and Reclaim Pride in Gothenburg, Sweden 2019
Authors: Wasshede Cathrin
Published: September 2020

In spite of the rainbow flag’s importance as a symbol for transnational queer belonging and its meanings for the survival of queers all over the world, much critical queer Anglo-Saxon research and activism concerning the rainbow flag and the celebration of Pride claims that it has lost its radical potential through processes of normalisation, mainstreaming, homonationalism and commercialisation. In order to address other queer political issues, alternative Pride events are organized in parallel with conventional Pride celebrations.

This chapter will discuss two Pride events held in Gothenburg, Sweden, in 2019, Reclaim Pride and Öckerö Pride, drawing on auto-ethnographic methods. It will reflect on two connected questions: What meanings, emotions, actions and temporalities are (re)produced as a result of the relationship between the events, the rainbow flag, the concept of Pride and the activists/participants—including the author? In what ways do the rainbow flag and the concept of Pride work as co-producers of belongings as well as disbelongings—and how does the author’s position as a Swedish, middle-class, white, lesbian, feminist, mother, former activist and now sociologist affect her feelings of belonging and disbelonging?

It is shown that the rainbow flag is a very topical and heated cultural artefact in the Swedish political arena, in which racism, homophobia and Islamophobia are growing. The author’s experiences and emotions at the two Pride events reflect the ambivalent struggle that takes place at the borders of belonging and disbelonging. Temporality and space are important aspects of the contextualisation that needs to be applied in order to grasp the different effects that processes of inclusion and exclusion have on queer people in different places and situations.
Pink Porn Economy: Genealogies of Transnational LGBTQ Organising
Authors: Laskar Pia
Published: September 2020

Studying pre-2000s pink porn magazines reveals the importance of politics in-between in the development of LGBTQ transnational organising in the twentieth century. The usual historical narratives of LGBTQ politics in the North are based on medical or legislative documents or on self-identified queers’ descriptions of their own interactions with these discourses. However, these discourses and data only capture parts of how twentieth-century queers developed sexual subjectivity, became nationally and transnationally organised, and conducted sexual politics. This chapter uses Claire Colebrook’s (Understanding Deleuze. Australia: Allen and Unwin, 2002) feminist engagement in Deleuze’s and Guattari’s concept device to discuss transnational political networks that rhizomatically connected the makers, disseminators and subscribers of male same-sex porn magazines produced in Denmark and Sweden between 1960 and 1980. The concepts enable an analysis of the messy entanglement of desire, subjectivity processes, consumption, organising and activism, and of the shaping of certain queer communities of belonging while also excluding others.  The application of gender analysis to the entanglement of pink porn economies in queer transnational networks sheds a genealogical light on the historical division between the emergence of vis-à-vis lesbian and gay networks and politics—and on the tensions between them regarding so-called positive or negative sexual rights in the decades to come.
A State Affair?: Notions of the State in Discourses on Trans Rights in Sweden
Authors: Alm Erika
Published: September 2020

Departing from previous scholarly work that has studied the effects of state violence and conditional state recognition on the living conditions of gender-variant people (Beauchamp 2019; Linander 2018), this chapter explores the function of narratives of the state in discourses on trans rights in Sweden. It provides insights into the relation between state and civil society, and the practicalities of governance, through an examination of how activists interpellate the state and hold it accountable. With a critical inquiry into the hegemonic narrative that the Swedish state has a responsibility to alleviate the suffering of gender-variant citizens as a background, it addresses and situates the tension between liberal rights discourses of trans rights on the one hand and transformative politics asking for restorative justice on the other hand (Spade 2011). The argument is that the interpellation of the state can be understood as a strategy to repoliticise the violent effects of governance in times of neoliberalism.
Melancholia and the New Biological Psychiatry
Authors: Jansson Åsa
Published: September 2020

This chapter centres on the development of a neurophysiological model of melancholia, which emerged within the new academic psychiatry in the German states at mid-century, and was taken up into British literature in the 1860s and 70s. It considers Wilhem Griesinger’s model of psychological reflex action, which he used to explain the aetiology of mental disorders. Building on Griesinger’s model, Richard von Krafft-Ebing in Germany and Henry Maudsley in Britain offered two of the period’s most comprehensive descriptions of melancholia as a modern biomedical mood disorder. Finally the new neurophysiological model of melancholia is considered in relation to neurasthenia, a fashionable diagnosis in the United States in the last quarter of the century.
Conclusion: Melancholia, Depression, and the Politics of Classification
Authors: Jansson Åsa
Published: September 2020

The conclusion briefly highlights some alternative models of melancholia at the turn of the twentieth century, before turning the focus to the decline of the melancholia diagnosis and the rise of clinical depression as the new dominant mood disorder in diagnostic literature. The Conclusion considers how the developments outlined in the previous chapters have been foundational not only for the modern psychiatric concepts ‘mood disorder’ and ‘clinical depression’, but also more broadly for classification and clinical practice in twentieth- and twenty-first-century psychiatry. Finally, the book turns the spotlight to the politics of psychiatric classification, and asks what is at work, and at stake, when psychiatry tries to label, classify, and diagnose psychological distress.
S-duality and supersymmetry on curved manifolds
Authors: Festuccia Guido , Zabzine Maxim
Published: September 2020

Abstract

We perform a systematic study of S-duality for $$ \mathcal{N} $$
N
= 2 supersymmetric non-linear abelian theories on a curved manifold. Localization can be used to compute certain supersymmetric observables in these theories. We point out that localization and S-duality acting as a Legendre transform are not compatible. For these theories S-duality should be interpreted as Fourier transform and we provide some evidence for this. We also suggest the notion of a coholomological prepotential for an abelian theory that gives the same partition function as a given non-abelian supersymmetric theory.

Published: September 2020

Purpose

To evaluate the outcome of robot-assisted residual mass resection (RA-RMR) in nonseminomatous germ cell tumor (NSGCT) patients with residual tumor following chemotherapy.

Patients and methods

Retrospective medical chart analysis of all patients with NSGCT undergoing RA-RMR at two tertiary referral centers between January 2007 and April 2019. Patients were considered for RA-RMR in case of a residual tumor between 10 and 50 mm at cross-sectional computed tomography (CT) imaging located ventrally or laterally from the aorta or vena cava, with normalized tumor markers following completion of chemotherapy, and no history of retroperitoneal surgery.

Results

A total of 45 patients were included in the analysis. The Royal Marsden stage before chemotherapy was IIA in 13 (28.9%), IIB in 16 (35.6%), IIC in 3 (6.7%) and IV in 13 patients (28.9%). The median residual tumor size was 1.9 cm (interquartile range [IQR] 1.4–2.8; range 1.0–5.0). Five procedures (11.1%) were converted to an open procedure due to a vascular injury (n = 2), technical difficulty (n = 2) or tumor debris leakage (n = 1). A postoperative adverse event occurred in two patients (4.4%). Histopathology showed teratoma, necrosis and viable cancer in 29 (64.4%), 14 (31.1%), and two patients (4.4%), respectively. After a median follow-up of 41 months (IQR 22–70), one patient (2.2%) relapsed in the retroperitoneum. The one- and 2-year recurrence-free survival rate was 98%.

Conclusion

RA-RMR is an appropriate treatment option in selected patients, potentially providing excellent cure rates with minimal morbidity. Long-term outcome data are needed to further support this strategy and determine inclusion and exclusion criteria.
The production of fuels and chemicals in the new world: critical analysis of the choice between crude oil and biomass vis-à-vis sustainability and the environment
Authors: Yadav Vikramaditya G. , Yadav Ganapati D. , Patankar Saurabh C.
Published: September 2020

Energy and the environment are intimately related and hotly debated issues. Today’s crude oil-based economy for the manufacture of fuels, chemicals and materials will not have a sustainable future. The over-use of oil products has done a great damage to the environment. Faced with the twin challenges of sustaining socioeconomic development and shrinking the environmental footprint of chemicals and fuel manufacturing, a major emphasis is on either converting biomass into low-value, high-volume biofuels or refining it into a wide spectrum of products. Using carbon for fuel is a flawed approach and unlikely to achieve any nation’s socioeconomic or environmental targets. Biomass is chemically and geographically incompatible with the existing refining and pipeline infrastructure, and biorefining and biofuels production in their current forms will not achieve economies of scale in most nations. Synergistic use of crude oil, biomass, and shale gas to produce fuels, value-added chemicals, and commodity chemicals, respectively, can continue for some time. However, carbon should not be used as a source of fuel or energy but be valorized to other products. In controlling CO2emissions, hydrogen will play a critical role. Hydrogen is best suited for converting waste biomass and carbon dioxide emanated from different sources, whether it be fossil fuel-derived carbon or biomass-derived carbon, into fuels and chemicals as well as it will also lead, on its own as energy source, to the carbon negative scenario in conjunction with other renewable non-carbon sources. This new paradigm for production of fuels and chemicals not only offers the greatest monetization potential for biomass and shale gas, but it could also scale down output and improve the atom and energy economies of oil refineries. We have also highlighted the technology gaps with the intention to drive R&D in these directions. We believe  this article will generate a considerable debate in energy sector and lead to better energy and material policy across the world.

A longitudinal study of static analysis warning evolution and the effects of PMD on software quality in Apache open source projects
Authors: Trautsch Alexander , Herbold Steffen , Grabowski Jens
Published: September 2020

Automated static analysis tools (ASATs) have become a major part of the software development workflow. Acting on the generated warnings, i.e., changing the code indicated in the warning, should be part of, at latest, the code review phase. Despite this being a best practice in software development, there is still a lack of empirical research regarding the usage of ASATs in the wild. In this work, we want to study ASAT warning trends in software via the example of PMD as an ASAT and its usage in open source projects. We analyzed the commit history of 54 projects (with 112,266 commits in total), taking into account 193 PMD rules and 61 PMD releases. We investigate trends of ASAT warnings over up to 17 years for the selected study subjects regarding changes of warning types, short and long term impact of ASAT use, and changes in warning severities. We found that large global changes in ASAT warnings are mostly due to coding style changes regarding braces and naming conventions. We also found that, surprisingly, the influence of the presence of PMD in the build process of the project on warning removal trends for the number of warnings per lines of code is small and not statistically significant. Regardless, if we consider defect density as a proxy for external quality, we see a positive effect if PMD is present in the build configuration of our study subjects.
Welding thermal stress diagrams as a means of assessing material proneness to residual stresses
Authors: Mishchenko Andrii , Scotti Américo
Published: September 2020

In this work, the proposal and appraisal of a method to describe in a quantitative manner the phenomenon of thermal stresses formation in welding at different heat-affected zone (HAZ) regions and under different cooling rates, by means of physical simulation, are explained. Under the denomination of welding thermal stress diagrams (WTSD), initially the concept and experimental arrangements needed to use the idea, based on a Gleeble simulator, are revealed. An approach to determine more realistic thermal cycles (peak temperature and heating/cooling rates) is introduced and applied. The method assessment was carried out by using specimens of a HSLA quenchable steel subjected to different cooling rates (covering a wide range of typical welding heat inputs) and peak temperatures (representing regions progressively farther away from the fusion line). The different thermal stress (TS) curves proved the concept based on the justification of the results. In addition, it was physically demonstrated that TS curves are governed mainly by two complex concurrent phenomena, namely contraction under restriction of heated areas and the expansibility of phase transformation. It was concluded that due to this balance, the highest residual stress (RS) does not occur either at slowest cooling rate or at fastest cooling rate. Nevertheless, the highest RS may not occur at the coarse grain zone either. TS progressively drops along the HAZ regions away from critical regions, and even at sub-critical regions there is tensile RS. Complementarily, it was also concluded that WTSD by physical simulation allows one to determine the deformation behaviour of a material as a function of temperature. This information can be used as input or calibration in modelling for thermal stress generation in steels.
Red Cell Distribution Width is Associated with 30-day Mortality in Patients with Spontaneous Intracerebral Hemorrhage
Authors: Pinho João , Silva Lénia , Quintas-Neves Miguel , Marques Leandro , Amorim José Manuel , Reich Arno , Ferreira Carla
Published: September 2020

Background

Red cell distribution width (RDW) has been associated with mortality and outcome in a wide variety of non-neurological and neurological diseases, namely in myocardial infarction and acute ischemic stroke, and the reason for this is not completely understood. We aimed to investigate RDW as a potential prognostic marker in patients with intracerebral hemorrhage (ICH).

Methods

This is a retrospective study of consecutive patients with acute non-traumatic ICH admitted to a single center during a 4-year period. We reviewed individual clinical records to collect demographic and baseline information, including RDW at admission, 3-month functional status, and incidence of death during follow-up. Baseline computed tomography imaging was reviewed to classify the location of ICH, and to measure ICH volume and perihematomal edema volume. Patients were divided according to quartile distribution of RDW (RDW-Q1-4).

Results

The final study population consisted of 358 patients, median age 71 years (interquartile range [IQR] 60–80), 55% were male, and median Glasgow Coma Scale was 14 (IQR 10–15), with a mean follow-up of 17.6 months. Patients with higher RDW values were older (p = 0.003), more frequently presented with an active malignancy (p = 0.005), atrial fibrillation (p < 0.001), intraventricular hemorrhage (p = 0.048), and were anticoagulated (p < 0.001). Three-month functional independence was similar throughout RDW quartiles. RDW-Q4 was independently associated with increased 30-day mortality (adjusted odds ratio = 3.36, 95%CI = 1.48–7.62, p = 0.004), but not independently associated with increased mortality after 30 days (adjusted hazards ratio = 0.71, 95%CI = 0.29–1.73, p = 0.448).

Conclusions

RDW is a robust and independent predictor of 30-day mortality in non-traumatic ICH patients, and further studies to understand this association are warranted.

Published: September 2020

Background

Multiple scores have been proposed to guide risk stratification after percutaneous coronary intervention. This study assessed the performance of the PRECISE-DAPT, PARIS and CREDO-Kyoto risk scores to predict post-discharge ischaemic or bleeding events.

Methods

A total of 1491 patients treated with latest-generation drug-eluting stent implantation were evaluated. Risk scores for post-discharge ischaemic or bleeding events were calculated and directly compared. Prognostic performance of both risk scores was assessed with calibration, Harrell’s c‑statistics net reclassification index and decision curve analyses.

Results

Post-discharge ischaemic events occurred in 56 patients (3.8%) and post-discharge bleeding events in 34 patients (2.3%) within the first year after the invasive procedure. C‑statistics for the PARIS ischaemic risk score was marginal (0.59, 95% confidence interval (CI) 0.51–0.68), whereas the CREDO-Kyoto ischaemic risk score was moderate (0.68, 95% CI 0.60–0.75). With regard to post-discharge bleeding events, CREDO-Kyoto displayed moderate discrimination (c-statistic 0.67, 95% CI 0.56–0.77), whereas PRECISE-DAPT (0.59, 95% CI 0.48–0.69) and PARIS (0.55, 95% CI 0.44–0.65) had a marginal discriminative capacity. Net reclassification index and decision curve analysis favoured CREDO-Kyoto-derived bleeding risk assessment.

Conclusion

In this contemporary all-comer population, PARIS and PRECISE-DAPT risk scores were not resilient to independent testing for post-discharge bleeding events. CREDO-Kyoto-derived risk stratification was associated with a moderate predictive capability for post-discharge ischaemic or bleeding events. Future studies are warranted to improve risk stratification with more focus on robustness and rigorous testing.

Published: September 2020

Intracerebral hemorrhage (ICH) prognostication during the acute phase is often subjective among physicians and often affects treatment decisions. The present study explores objective imaging parameters using quantitative corticospinal tract (CST) fiber reconstruction during the acute phase of ICH and correlates these parameters with functional outcome and patient recovery. We prospectively enrolled nonsurgical spontaneous supratentorial ICH patients and obtained an MRI scan on day 5 ± 1. Q-space diffeomorphic reconstruction was performed using DSI Studio, and quantitative anisotropy (QA) was calculated. The CST was reconstructed based on QA. The dichotomized modified Rankin Scale score on day 90 (favorable outcome = 0–2) and Barthel Index (favorable recovery = 100 on day 90 or improvement between discharge and day 90 > 60%) were assessed. Thirty-three patients, median age 72 years (interquartile range (IQR) 64–83), 21 female (64%), 21 (64%) with lobar hemorrhage, median ICH volume on admission 15.0 (IQR 7.0–27.4) mL, were included. Sixteen patients (48%) had a favorable outcome and 24 (73%) had a favorable recovery. The mean number of ipsilesional reconstructed CST fiber pathways was higher in patients with favorable outcomes (153 (standard deviation (SD) 103) vs. 60 (SD 39), p = 0.003) and predicted outcome after adjustment (Exp(B) = 1.016 (95% CI = 1.002–1.030)). QA in the ipsilesional posterior limb of the internal capsule showed a trend towards an association with favorable outcome (Exp(B) = 1.194 (95% CI = 0.991–1.439 (adjusted))). The total (ipsilesional + contralesional) number of reconstructed fiber pathways was associated with favorable recovery (Exp(B) = 1.025 (95% CI = 1.003–1.047 (adjusted))). Quantitative tractography parameters assessed in the acute phase of ICH may represent a promising predictor of long-term outcome and recovery. This might facilitate prognostic evaluation and organization of rehabilitation.
Importance and Feasibility of Animal Welfare Measures from a Consumer Perspective in Germany
Authors: Winkel Carolin , Schukat Sirkka , Heise Heinke
Published: September 2020

The subject animal welfare is increasingly in the public discourse. Consumers and policymakers are increasingly demanding products that are produced under increased animal welfare standards. The profession of the farmer involuntarily gets into disrepute. Many consumers want fundamental changes in pig farming, but are not aware of the consequences of implementation. In this representative study, consumers (n = 1101) were asked about their assessment of 33 animal welfare measures with regard to their importance and the feasibility of implementing those measures. With the help of a four-field matrix, both the perceived importance and the feasibility of the animal welfare measures surveyed were brought together. The results show four possibilities: important and easy to implement, important and not feasible, not important and easy to implement as well as not important and not feasible. The results show that any outdoor access to pasture ranks first, followed by any outdoor access to straw bedding. The results can make a significant contribution to future communication with critical consumers concerning the implementation of higher animal welfare levels, as it becomes clearer how realistic consumers are about the feasibility of several animal welfare measures. Furthermore, the results could prove useful for the design of animal welfare programs and could help famers making targeted decisions concerning stable construction and management.
Spatial winding: cooperative heterogeneous multi-robot system for fibrous structures
Authors: Duque Estrada Rebeca , Kannenberg Fabian , Wagner Hans Jakob , Yablonina Maria , Menges Achim
Published: September 2020

This research presents a cooperative heterogeneous multi-robot fabrication system for the spatial winding of filament materials. The system is based on the cooperation of a six-axis robotic arm and a customized 2 + 2 axis CNC gantry system. Heterogeneous multi-robot cooperation allows to deploy the strategy of Spatial Winding: a new method of sequential spatial fiber arrangement, based on directly interlocking filament-filament connections, achieved through wrapping one filament around another. This strategy allows to create lightweight non-regular fibrous space frame structures. The new material system was explored through physical models and digital simulations prior to deployment with the proposed robotic fabrication process. An adaptable frame setup was developed which allows the fabrication of a variety of geometries within the same frame. By introducing a multi-step curing process that integrates with the adaptable frame, the iterative production of continuous large-scale spatial frame structures is possible. This makes the structure’s scale agnostic of robotic reach and reduces the necessary formwork to the bare minimum. Through leveraging the capacities of two cooperating machines, the system allows to counteract some of their limitations. A flexible, dynamic and collaborative fabrication system is presented as a strategy to tailor the fiber in space and expand the design possibilities of lightweight fiber structures. The artifact of the proposed fabrication process is a direct expression of the material tectonics and the robotic fabrication system.
The future of design cognition analysis
Authors: Hay Laura , Cash Philip , McKilligan Seda
Published: September 2020

‘Design cognition’ refers to the mental processes and representations involved in designing, and has been a significant area of interest since the emergence of design research in the 1960s. The field now faces significant challenges moving into the future, with major change required to overcome stagnation in research topics and methodologies. Tackling these challenges requires us to understand the past and present of design cognition research, and open fresh discussions on its future. This thematic collection aims to address this need by taking stock of current approaches, exploring emerging topics and methodologies, and identifying future directions for enquiry. In this editorial, we examine key issues regarding bothwhatwe investigate andhowwe conduct this research. We present a vision formed from a structured literature review, the work of authors in the collection, and the views of a broad cross-section of the design cognition community. This vision is formalized in a roadmap from the present to the near and far future, highlighting key topics and research questions for the field. Ultimately, ecological measurement, new applications of artificial intelligence, and a move towards theory construction and research maturation constitute key long term challenges for the design cognition community.

Two new families and three new genera and species of Crinoidea from the Icla and Belén formations, Bolivian Devonian, are described. The material is identified asMeperocrinus angelinan. gen. n. sp., from the Icla Formation of the Sub-Andina region,Tuberocrinus lapazensisn. gen. n. sp. andAenigmaticumcrinus rochacamposin. gen. n. sp., both from the Belén Formation of the Bolivian Altiplano.Meperocrinus angelinan. gen. n. sp. is an Emperocrinidae, a family described from the Silurian of the United States of America.Tuberocrinus lapazensisn. gen. n. sp. is assigned to a new family of Dimerocrinitacea, the Tuberocrinidae n. fam., which is closely related to Pterinocrinidae that already has representatives in Bolivia (Apurocrinus sucreiMcIntosh), Argentina (Pterinocrinus?australisHaude), and Colombia (Bogotacrinus scheibeiMcIntosh).Aenigmaticumcrinus rochacamposin. gen. n. sp. is also as assigned to a new family of Dimerocrinitacea, the Aenigmaticumcrinidae n. fam.; a family with very distinctive features. These data demonstrate that the Malvinokaffric crinoid fauna in Bolivia has a mixed origin, with forms that arrived in South America from Europe (Old World Realm) and United States of America (Eastern America Realm) during the late Silurian or earliest Devonian, as well as a local stock, which evolved to highly endemic lineages.

Toward an understanding of cosmopolitanism in deep time: a case study of ammonoids from the middle Permian to the Middle Triassic
Authors: Dai Xu , Song Haijun
Published: September 2020

Cosmopolitanism occurred recurrently during the geologic past, especially after mass extinctions, but the underlying mechanisms remain poorly known. Three theoretical models, not mutually exclusive, can lead to cosmopolitanism: (1) selective extinction in endemic taxa, (2) endemic taxa becoming cosmopolitan after the extinction and (3) an increase in the number of newly originated cosmopolitan taxa after extinction. We analyzed an updated occurrence dataset including 831 middle Permian to Middle Triassic ammonoid genera and used two network methods to distinguish major episodes of ammonoid cosmopolitanism during this time interval. Then, we tested the three proposed models in these case studies. Our results confirm that at least two remarkable cosmopolitanism events occurred after the Permian–Triassic and late Smithian (Early Triassic) extinctions, respectively. Partitioned analyses of survivors and newcomers revealed that the immediate cosmopolitanism event (Griesbachian) after the Permian–Triassic event can be attributed to endemic genera becoming cosmopolitan (model 2) and an increase in the number of newly originated cosmopolitan genera after the extinction (model 3). Late Smithian cosmopolitanism is caused by selective extinction in endemic taxa (model 1) and an increase in the number of newly originated cosmopolitan genera (model 3). We found that the survivors of the Permian–Triassic mass extinction did not show a wider geographic range, suggesting that this mass extinction is nonselective among the biogeographic ranges, while late Smithian survivors exhibit a wide geographic range, indicating selective survivorship among cosmopolitan genera. These successive cosmopolitanism events during severe extinctions are associated with marked environmental upheavals such as rapid climate changes and oceanic anoxic events, suggesting that environmental fluctuations play a significant role in cosmopolitanism.

Variations in temperature can affect the development of nematophagous fungi, especially when they are used in the biological control of parasitic nematodes in the pastures where cattle are reared. The aim of this work was to evaluate the effects of temperature on the performance of nematophagous fungi in the biological control of bovine parasitic nematodes. The mycelial growth, chlamydospore production and nematicidal activity ofDuddingtonia flagrans, Arthrobotrys cladodesandPochonia chlamydosporiawere evaluated at 15, 20, 25, 30 and 35°C. The fungal strains achieved mycelial growth, chlamydospore production and nematicidal activity on parasitic nematodes under all temperature conditions tested. The fungi showed higher growth at intermediate temperatures (20, 25 and 30°C) than at the extremes of 15 and 35°C. At 25 and 30°C,D. flagransrealized 96.8 and 94.5% nematicidal activity on bovine parasitic nematodes, respectively.Arthrobotrys cladodeseffected nematicidal activity of 85.3 and 83.5%, at 20 and 25°C, respectively. At 20 and 30°C,P. chlamydosporiaachieved nematicidal activity of 81.3 and 87.4%, respectively. The maximum chlamydospore production was reached at 20, 25 and 30°C forD. flagrans, at 20 and 25°C forA. cladodesandP. chlamydosporia.The results of this study demonstrated that the tested fungal strains ofD. flagrans, A. cladodesandP. chlamydosporia,when used in the biological control of bovine parasitic nematodes, were not limited byin vitrotemperature variations. Therefore, the use of these strains of fungi as biological control agents of parasitic nematodes is promising.

Published: September 2020

Background

Peri-orbital surgical emphysema is a rare complication that can occur after lacrimal surgery. It has only been described in isolated cases, following external dacryocystorhinostomy (n = 2) and Lester Jones tube insertion (n = 1).

Method

A retrospective, non-comparative case series was conducted of patients who developed surgical emphysema following endoscopic dacryocystorhinostomy.

Results

A total of 356 endoscopic dacryocystorhinostomy cases (primary, n = 316; revision, n = 40) were performed over a six-year period. Seven cases of post-operative surgical emphysema were identified, all of which were preceded by uncontrolled sneezing, nose-blowing or coughing within the first week of surgery. The occurrence of surgical emphysema post-endoscopic dacryocystorhinostomy in our centre was 7 in 356, or 2 per cent, over six years.

Conclusion

This is the first study to report the occurrence of surgical emphysema post-endoscopic dacryocystorhinostomy. Clinicians may wish to suggest patients stifle the aforementioned triggers within the first week to reduce the potential for surgical emphysema.
‘The words has been immigrate’: Chronotopes in context-shaping narrative co-construction about Taiwanese loanwords with Taiwanese Americans
Authors: Wang Ping-Hsuan
Published: September 2020

This study argues for the analytical validity of the chronotope in research on context by examining a conversational narrative between Taiwanese and Taiwanese Americans. It offers an endogenous view of context in the sense that chronotopes are anchored by how participants invoke specific time-space representations relevant to the active shaping of context. Furthermore, it adds a historical dimension to the understanding of context as multi-layered in meaning. In the data, participants’ discussion of Taiwanese loanwords creates three connected chronotopes that draw on Taiwan's transnational history for the narrative co-construction. Finally, the chronotopic analysis demonstrates how identities emerge as time-space coordinates—seventeenth-century Dutch in Taiwan and twenty-first-century Taiwanese in the US—and are used as resources to map a shared background with a Taiwanese origin. The study applies the notion of the chronotope outside of the interview setting and contributes to a more laminated theorization of context in naturally occurring conversation.

The decentralisation of death? Local budgets and organised crime violence
Authors: Arends Helge
Published: September 2020

Fiscal decentralisation theory calls for enhanced local revenue and spending responsibilities to promote the efficiency of public service delivery. However, some have pointed to the danger of local capture cancelling out these effects. I examine the argument that organised crime violence (OCV) intensifies as mafias fight for access to local government resources, which they consider an attractive income source. I regress violence on local spending (LS) in Mexican municipalities over the period 1995–2015. I find a significant relationship between LS and the intensity of violence: higher levels of LS per capita are strongly related to higher homicide rates, conditional on them being positive. However, LS does not determine the probability of OCV taking place in the first place. The results suggest that caution should be exercised when initiating decentralisation reforms in the context of local capture and OCV.
‘Behind the Digi-God's back’: social representations of older people's digital competences and internet use in regional Finnish newspapers
Authors: Rasi Päivi
Published: September 2020

This article discusses how three Finnish regional newspapers represented older people's digital competences and internet use in their daily coverage. The study explored media representations from the perspective of social representations and sought to answer the following questions: In what kind of internet user roles do the articles portray older people? How and with what kind of images do the articles portray older people's digital competences in various internet user roles? How are older people positioned at a societal level in the articles? The analysis revealed that older people were portrayed as incompetent outcasts of a digitalised society. However, there was a clear difference according to whether older people were portrayed as recipients of public services or as consumers of private services. As targets of public services, older people were predominantly portrayed as happy targets, who welcomed the services provided for them. This result can be interpreted as part of the promotion of government digitalisation policies.
On the Semantics of Abstract Argumentation Frameworks: A Logic Programming Approach
Authors: Alfano Gianvincenzo , Greco Sergio , Parisi Francesco , Trubitsyna Irina
Published: September 2020

Recently there has been an increasing interest in frameworks extending Dung’s abstract Argumentation Framework (AF). Popular extensions include bipolar AFs and AFs with recursive attacks and necessary supports. Although the relationships between AF semantics and Partial Stable Models (PSMs) of logic programs has been deeply investigated, this is not the case for more general frameworks extending AF.

In this paper we explore the relationships between AF-based frameworks and PSMs. We show that every AF-based framework Δ can be translated into a logic program PΔ so that the extensions prescribed by different semantics of Δ coincide with subsets of the PSMs of PΔ. We provide a logic programming approach that characterizes, in an elegant and uniform way, the semantics of several AF-based frameworks. This result allows also to define the semantics for new AF-based frameworks, such as AFs with recursive attacks and recursive deductive supports.
