Loose One-Way Coupling of Land Use and Nutrient Emission Models to Assess Effects of Regional Development Scenarios on Catchment Water Quality
Authors: Mockler Eva M , Shahumyan Harutyun , Williams Brendan , Bruen Michael
Published: May 2020

Nutrient enrichment and eutrophication can increase when urbanisation and intensification of agriculture production occurs without accompanying mitigation measures to offset impacts from land use transitions. The identification of measures to protect or restore water quality is a challenging exercise, particularly in the context of increasing population and urbanisation. Hence, decision-makers need adequate tools to better understand and evaluate the effects of policy interventions on water management and quality control in urban regions. A model integration method was developed to assess future scenarios of urban development on water quality using land use model Monitoring Land Use/Cover Dynamics and nutrient emission model Source Load Apportionment Model. A case study application investigated how projected changes in urban land use in the most populated region of Ireland, the Greater Dublin Region, impact on water quality. Results for all scenarios indicate increasing losses to water for both phosphorus (18–25%) and nitrogen (9–12%). However, as these scenarios assume that wastewater treatment efficiencies remain static into the future, this study highlights that the magnitude and distribution of investment in urban wastewater collection and treatment will have the greatest impact on changes in future nutrient emissions to water in this urban region. The differences between the development scenarios for diffuse nutrient losses were small in comparison, even though the location of specific land uses varied broadly across scenarios. It was found that the decline of agricultural land cover and replacement with urban development in Dublin region by 2026 as represented by four modelled scenarios resulted in substantial increases in diffuse phosphorus emissions, but only slight changes in diffuse nitrogen emissions. It was shown that the scales of impact from sources of nutrients vary from scenario to scenario and that these should be considered alongside planned mitigation of point sources of nutrient emissions to water. Such information can support physical planners, catchment managers and policy makers to plan accordingly to get the best possible environmental outcomes. The case study application demonstrated that the loose one-way coupling of a land use model and a nutrient emission model can be an effective and inexpensive approach to improve understanding of the effects of urbanisation on water quality and assist in the strategic planning of catchment management and infrastructure investment.
Navigation and Indexical Thought
Authors: Stokke Andreas
Published: May 2020

This paper argues for a moderate form of essentialism about indexical thought (also known asde se, first-person, or egocentric thought). According to this moderate essentialism, there is a significant category of intentional action that necessarily involves indexical thought. This category of action is navigation, that is, intentionally moving from one location to another by using public information about the world such as a map or a set of directions. It is shown that anti-essentialists face a challenge in accounting for this kind of action without accepting the involvement of indexical thought or something equivalent. The conclusion that navigation necessarily requires indexical thought is neutral on the strong essentialist claim that there is a special class of indexical propositional attitudes that mandate rejecting standard theories of propositional attitudes. The conclusion is also neutral on the strong essentialist claim that any kind of intentional action necessarily requires indexical thought.
Easier to Say ‘Recovery’ than to Do Recovery: Employees’ Experiences of Implementing a Recovery-Oriented Practice
Authors: Kvia Aasa , Dahl Christel , Grønnestad Trond , Frahm Jensen Målfrid J.
Published: May 2020

The aim is to investigate the change towards a recovery-supporting model for health care services in a Norwegian municipality. The model is founded on the five processes identified by Leamy et al. (British Journal of Psychiatry, 199,445–452, 2011): Connectedness, Hope, Identity, Meaning and Empowerment, described as the acronym CHIME. To examine this change, we used focus groups, which provided a basis for qualitative content analysis. The participants were recruited from several departments of the Mental Health and Substance Use unit. We found three themes: reflections on attitudes and actions, patients not participating in matters regarding their situation, balancing paternalistic attitudes and patients’ autonomy. The findings suggest that workers have an understanding of recovery but do not know what to do differently. We advocate that there is a need for tools, mechanisms and structures onhowto support a recovery-oriented approach for patients needing mental health and substance use treatment.
Changes in the Expression of SNAP-25 Protein in the Brain of Juvenile Rats in Two Models of Autism
Authors: Lenart Jacek , Bratek Ewelina , Lazarewicz Jerzy W. , Zieminska Elzbieta
Published: May 2020

The results of genetic studies suggest a possible role for SNAP-25 polymorphism in the development of autism spectrum disorders (ASDs); however, there are no data available on whether changes in SNAP-25 expression also affect animals in rodent models of ASD. The aim of the present study was to explore this issue. The studies included 1-month-old rats representing valproic acid (VPA)- and thalidomide (THAL)-induced models of autism. Their mothers received single doses of VPA (800 mg/kg) or THAL (500 mg/kg) per os on the 11th day of gestation. SNAP-25 protein content in the cerebellum, hippocampus, and frontal lobe was determined using Western blotting, while changes of mRNA levels of Snap25 gene were determined using real-time polymerase chain reaction. Compared to controls, SNAP-25 content was decreased by approximately 35% in all brain structures tested, in both males and females, exclusively in the VPA group. In contrast to this, Snap25 expression, studied in males, was increased in the hippocampus and cerebellum in both, VPA- and THAL-treated rats. We discuss the compliance of these results with the hypothesized role of SNAP-25 in the pathophysiology of ASD and the adequacy of the experimental models used.
Verifiability and Symptom Endorsement in Genuine, Exaggerated, and Malingered Pain
Authors: Akca Y. E. Ali , Slootmaekers Lotte , Boskovic Irena
Published: May 2020

The current study has investigated whether pure malingering, in which reported symptoms are nonexistent, partial malingering, in which existent symptoms are exaggerated, and genuine symptoms could be differentiated by applying the verifiability approach (VA) and the Self-Report Symptom Inventory (SRSI). The logic behind the VA is that deceivers’ statements contain more non-verifiable information, whereas truth tellers’ accounts include more verifiable details. The SRSI taps into over-reporting by including a mix of genuine symptoms and implausible complaints (pseudosymptoms). We checked if participants (N = 167) allocated to one of three conditions (pure malingerers vs. exaggerators vs. truth tellers) can be differentiated in their pain symptom reports’ (non)verifiability and symptom endorsement. Findings revealed that deceptive reports were lengthier than truthful statements. However, this difference was not produced by a discrepancy in non-verifiable details, but rather by a higher production of verifiable information among malingerers and exaggerators. Thus, contrary to previous findings, our results indicate that pain reports rich in verifiable information should raise doubt about their veracity. Further, truth tellers endorsed less symptoms of the SRSI than exaggerators, but not than pure malingerers. Pure malingerers and exaggerators did not differ in symptom endorsement. Thus, our findings revealed that when compared with truth tellers, exaggerators exhibited stronger over-reporting tendencies than (pure) malingerers. However, due to inconsistent findings, further investigation of the efficacy of these methods in differentiation between exaggerated and malingered reports is required.

From Malthusian Disequilibrium to the Post-Malthusian Era: The Evolution of the Preventive and Positive Checks in Germany, 1730–1870
Authors: Pfister Ulrich , Fertig Georg
Published: May 2020

This study draws on a new data set of vital rates and real wages to explore short-term and long-term behavior of the preventive and positive checks in a major economy of premodern mainland Europe. Four results stand out. First, the preventive check was fairly stable throughout the period 1730–1870; its magnitude of 0.2 to 0.35 was comparable with that of England, northern and central Italy, and Sweden. Second, the eighteenth century was characterized by Malthusian disequilibrium in that there was no long-term relationship between the crude death rate and the real wage, whereas the crude death rate’s instantaneous response to income changes was a substantial –0.4. Third, the short-term positive check may have weakened over the eighteenth century and largely disappeared in the 1810s. The diversification of food risk resulting from the spread of potato cultivation, market integration, and the development of the nonagricultural sectors are potential explanations of the demise and disappearance of the positive check. Fourth, between the 1810s and the 1860s, vital rates and the real wage were stationary, which is consistent with a post-Malthusian regime in which technological progress depended on population size. The 1810s marked the time when Germany transited from a Malthusian regime in disequilibrium to the post-Malthusian era.
Self-selection of Asylum Seekers: Evidence From Germany
Authors: Guichard Lucas
Published: May 2020

I examine the pattern of selection on education of asylum seekers recently arrived in Germany from five key source countries: Afghanistan, Albania, Iraq, Serbia, and Syria. The analysis relies on original individual-level data collected in Germany combined with surveys conducted at origin. The results reveal a positive pattern of selection on education for asylum seekers who were able to flee Iraq and Syria, and the selection is neutral for individuals seeking asylum from Afghanistan and negative for asylum seekers from Albania and Serbia. I provide an interpretation of these patterns based on differences in the expected length of stay at destination, the migration costs faced by asylum seekers to reach Germany, and the size of migration networks at destination.
Approaches to Inclusion and Social Participation in School for Adolescents with Autism Spectrum Conditions (ASC)—a Systematic Research Review
Authors: Lüddeckens Johanna
Published: May 2020

This systematic research review identifies approaches of inclusive education concerning adolescents with autism spectrum (ASC) without intellectual disability (ID). The definitions of inclusion, whose perspectives are taken into account, approaches, and the implications suggested for best practices are reviewed in the articles included in this study. The results show how inclusion is defined as a sense of social acceptance and an approach that physical placement in a regular class can lead to social participation. Taking into account students’ perspectives is seen as important. Implications for best practice include information on how to improve school personnel’s reflections on their responsibilities and expectations of students with disabilities and points to difficulties for teachers in meeting the diversity of students in the classroom.
Which Prior Mathematical Knowledge Is Necessary for Study Success in the University Study Entrance Phase? Results on a New Model of Knowledge Levels Based on a Reanalysis of Data from Existing Studies
Authors: Rach Stefanie , Ufer Stefan
Published: May 2020

The transition from school to tertiary mathematics courses, which involve advanced mathematics, is a challenge for many students. Prior research has established the central role of prior mathematical knowledge for successfully dealing with challenges in learning processes during the study entrance phase. However, beyond knowing that more prior knowledge is beneficial for study success, especially passing courses, it is not yet known how a level of prior knowledge can be characterized that is sufficient for a successful start into a mathematics program. The aim of this contribution is to specify the appropriate level of mathematical knowledge that predicts study success in the first semester. Based on theoretical analysis of the demands in tertiary mathematics courses, we develop a mathematical test with 17 items in the domain of Analysis. Thereby, we focus on different levels of conceptual understanding by linking between different (in)formal representation formats and different levels of mathematical argumentations. The empirical results are based on a re-analysis of five studies in which in sum 1553 students of bachelor mathematics and mathematics teacher education programs deal with some of these items in each case. By identifying four levels of knowledge, we indicate that linking multiple representations is an important skill at the study entrance phase. With these levels of knowledge, it might be possible to identify students at risk of failing. So, the findings could contribute to more precise study advice and support before and while studying advanced mathematics at university.
Political corruption and the congestion of controllability in social networks
Authors: Solimine Philip C.
Published: May 2020

By viewing political and social corruption through the lens of the control theory of complex systems, this paper will provide some insight into the effects of corruption and outside control on incentives which direct the formation and evolution of social networks, and the intrinsic hierarchies which they encode. This paper proposes and tests the hypothesis that changes in the rate of competition among nodes to raise their control capacity, incentivized by the anticipation of payment through political corruption opportunities, can be identified by changes in an indicator of the controllability of the network at points where the network undergoes a structural change. A theoretical model of control input preference is formulated which leads to a testable hypothesis about the direction of correlation between controllability of a network and the presence of corruption. Results support the hypothesis that as corruption increases, the network becomes more difficult to control as all members alter their linking strategies to ensure that they get a piece of the action. We describe this novel effect as “hierarchical congestion”, to reflect the emergent phenomenon in which individuals making effort to move themselves to the top of the controllability hierarchy increase the number of driver nodes required to fully control the network.
Pharmacological Treatment of Fibrosis: a Systematic Review of Clinical Trials
Authors: Siani Alessandro
Published: May 2020

The term “fibrosis” refers to a spectrum of connective tissue disorders characterized by the excessive accumulation of extracellular matrix leading to organ dysfunction and, ultimately, failure. Fibrosis affects millions of patients worldwide and often manifests itself as a late-stage pathological condition associated with poor prognostic outcome. Although the aetiology and clinical course vary widely depending on the affected organ, fibrotic degeneration of different tissues is underpinned by similar molecular and cellular mechanisms, most notably the persistence and dysregulated activity of myofibroblasts. A systematic search of clinical trials was conducted using PubMed and Cochrane to qualitatively evaluate the effectiveness of different therapeutic approaches to the pharmacological targeting of myofibroblasts in patients affected by fibrotic disorders. The systematic search and screening returned 54 eligible clinical trials, 38 of which reported an improvement of the patients’ symptoms following treatment. The majority of the eligible articles focused on fibrotic degeneration of the respiratory system, skin, liver, and kidneys. The evaluation of clinical data unearthed commonalities between strategies that successfully ameliorated symptoms in patients affected by the same fibrotic disorder. However, none of the treatments evaluated in this study could improve symptoms across a range of fibrotic pathologies. These results indicate that, although no “one size fits all” treatment for fibrosis has yet been identified, the systematic analysis of clinical data can be used to inform the development of therapeutical strategies tailored to suit the diverse aetiology of each fibrotic condition.
Quantification of the Land Potential for Scaling Agroforestry in South Asia

Published: May 2020

Trees are an integral part of the sustainable farming practices that can withstand extreme weather events, pest risks, and optimize land and water productivity to achieve food, fuel, fodder and nutritional security while safeguarding the environmental flows. This study was undertaken to analyze the landscape potential for the South Asian region in the geospatial domain utilizing the FAO’s land suitability criteria. The key datasets were derived from satellite remote sensing at a global and regional scale for land, soil, climate, and topography and were used to model the agroforestry suitability across South Asia. Furthermore, the agroforestry suitability categories and tree cover dominance were investigated with respect to the total geographical area, agriculture land cover and with climate variables to understand the present and future trends. The comprehensive analysis revealed that 69% of the total geographical area retains 55% and greater suitability for agroforestry. The analysis revealed that nearly 73.4% of the landscape is absent (0%) of tree cover, 7.1%, shows 1–10% and 19.5% area having more than 10% tree cover. The tree dominance/hotspot analyses in the agriculture land were found notably high in the multiple farming components such as home gardens. The single crop of irrigated and rain-fed croplands showed high land suitability towards agroforestry. Such land can be utilized to enhance the tree cover that suits locally as per the farmer's need based on a community-driven participatory approach to bring the sustainability and resilience in degraded landscapes (FAO in Agroforestry for landscape restoration, 2017). The future climate data analysis showed a significant change in the distribution of temperature and precipitation that will influence future farming practices in South Asia. The agroforestry suitability and tree cover mapping results/analysis will assist crucially the agroforestry policymakers/planners in the various South Asian countries to implement and extend it to the new area. The analysis clearly shows that the advent of big data, remote sensing and GIS provide insights into the agroforestry interventions and scaling which further helps in building resilient landscapes for sustainable agri-food systems, livelihoods, safeguarding the environmental security and supporting some of the important sustainable development goals (SDGs).

Authors: Lai Xue‐Li , Wang Hai‐Yan , Guo Zhi‐Yong
Published: May 2020

The World Health Organization characterized coronavirus disease (COVID‐19) as a pandemic on March 11, 2020. Peritoneal dialysis patients have a weakened immune system that is associated with a high morbidity of infection. Thus, COVID‐19 prevention measures and management for patients on peritoneal dialysis are urgent and critical. Based on published research on COVID‐19 and previous clinical practices for similar coronavirus outbreaks, we aimed to make recommendations to manage patients undergoing peritoneal dialysis.
Evidence for the management of challenging behaviours in patients with acute traumatic brain injury or post-traumatic amnesia: An Umbrella Review
Authors: Block Heather , George Stacey , Milanese Steve , Dizon Janine , Bowen-Salter Holly , Jenkinson Felicity
Published: May 2020

Objective:

To synthesise the current best evidence on both pharmacological and non-pharmacological behaviour management interventions for adult patients in the acute hospital setting with traumatic brain injury (TBI) or post-traumatic amnesia (PTA).

Data Sources:

A comprehensive search of 10 electronic databases was completed.

Study Selection:

Systematic reviews (SRs) published in English before September 2018 were included. Initial search resulted in 4604 citations, 2916 for title and abstract screening with duplicates removed, and 2909 articles failed to meet the inclusion criteria leaving seven reviews for inclusion. Five reporting pharmacological management approaches, two reporting non-pharmacological management approaches, and one reporting both pharmacological and non-pharmacological management approaches.

Data Extraction:

Methodological quality was assessed independently by two reviewers using the Critical Appraisal Skills Programme Tool for SRs. Data were extracted from the studies based on the recommendations of the Joanna Briggs Institute (JBI) Methodology for JBI Umbrella Reviews.

Data Synthesis:

The SRs were of low-to-moderate quality overall. High-quality SRs were characterised by low numbers of studies and significant biases. The evidence relating to pharmacological interventions demonstrates low level and variable quality. The evidence relating to non-pharmacological interventions was limited and of low quality.

Conclusions:

The current evidence for the management of challenging behaviours in patients with acute TBI/PTA is generally equivocal, potentially reflecting the heterogeneity of patients with TBI and their clinical behaviours. More studies with rigorous methodologies are required to investigate the most suitable pharmacological and non-pharmacological behavioural interventions for the acute phase of TBI or PTA.
Ethical, Legal, and Social Challenges in the Development and Implementation of Disaster Telemedicine
Authors: Tedeschi Christopher
Published: May 2020

In recent years, advances in communications technology and market factors have led to a substantial expansion of telemedicine practice. One potential use of telemedicine is in disaster response, both as a resource for responders as well as a direct link to patients. The advantages of using telehealth to assist in disaster response are accompanied by important questions related to social impact, ethical implications, and regulatory oversight. A narrative review of several of these issues is presented here. The next steps in the development of a robust disaster telemedicine system will include the development of best practices and ethical guidelines agreed upon by all stakeholders, as well as the development of public-private partnerships geared at providing the highest quality disaster telemedicine to the greatest possible number of patients.

Telephonic communication produced superior acceptance rates overall and when analyzed by intervention type and provider.
Records for time-dependent stationary Gaussian sequences
Authors: Falk Michael , Khorrami Chokami Amir , Padoan Simone A.
Published: May 2020

For a zero-mean, unit-variance stationary univariate Gaussian process we derive the probability that a record at the time n, say
$X_n$
, takes place, and derive its distribution function. We study the joint distribution of the arrival time process of records and the distribution of the increments between records. We compute the expected number of records. We also consider two consecutive and non-consecutive records, one at time j and one at time n, and we derive the probability that the joint records
$(X_j,X_n)$
occur, as well as their distribution function. The probability that the records
$X_n$
and
$(X_j,X_n)$
take place and the arrival time of the nth record are independent of the marginal distribution function, provided that it is continuous. These results actually hold for a strictly stationary process with Gaussian copulas.
A unifying approach to branching processes in a varying environment
Authors: Kersting Götz
Published: May 2020

Branching processes $(Z_n)_{n \ge 0}$ in a varying environment generalize the Galton–Watson process, in that they allow time dependence of the offspring distribution. Our main results concern general criteria for almost sure extinction, square integrability of the martingale $(Z_n/\mathrm E[Z_n])_{n \ge 0}$, properties of the martingale limit W and a Yaglom-type result stating convergence to an exponential limit distribution of the suitably normalized population size $Z_n$, conditioned on the event $Z_n \gt 0$. The theorems generalize/unify diverse results from the literature and lead to a classification of the processes.
On first passage times of sticky reflecting diffusion processes with double exponential jumps
Authors: Song Shiyu , Wang Yongjin
Published: May 2020

We explore the first passage problem for sticky reflecting diffusion processes with double exponential jumps. The joint Laplace transform of the first passage time to an upper level and the corresponding overshoot is studied. In particular, explicit solutions are presented when the diffusion part is driven by a drifted Brownian motion and by an Ornstein–Uhlenbeck process.
Optimal stopping for the exponential of a Brownian bridge
Authors: de Angelis Tiziano , Milazzo Alessandro
Published: May 2020

We study the problem of stopping a Brownian bridgeXin order to maximise the expected value of an exponential gain function. The problem was posed by Ernst and Shepp (2015), and was motivated by bond selling with non-negative prices.

Due to the non-linear structure of the exponential gain, we cannot rely on methods used in the literature to find closed-form solutions to other problems involving the Brownian bridge. Instead, we must deal directly with a stopping problem for a time-inhomogeneous diffusion. We develop techniques based on pathwise properties of the Brownian bridge and martingale methods of optimal stopping theory, which allow us to find the optimal stopping rule and to show the regularity of the value function.
Association between overall fruit and vegetable intake, and fruit and vegetable sub-types and blood pressure: the PRIME study (Prospective Epidemiological Study of Myocardial Infarction)

Increased fruit and vegetable (FV) intake is associated with reduced blood pressure (BP). However, it is not clear whether the effect of FV on BP depends on the type of FV consumed. Furthermore, there is limited research regarding the comparative effect of juices or whole FV on BP. Baseline data from a prospective cohort study of 10 660 men aged 50–59 years examined not only the cross-sectional association between total FV intake but also specific types of FV and BP in France and Northern Ireland. BP was measured, and dietary intake assessed using FFQ. After adjusting for confounders, both systolic BP (SBP) and diastolic BP (DBP) were significantly inversely associated with total fruit, vegetable and fruit juice intake; however, when examined according to fruit or vegetable sub-type (citrus fruit, other fruit, fruit juices, cooked vegetables and raw vegetables), only the other fruit and raw vegetable categories were consistently associated with reduced SBP and DBP. In relation to the risk of hypertension based on SBP >140 mmHg, the OR for total fruit, vegetable and fruit juice intake (per fourth) was 0·95 (95 % CI 0·91, 1·00), with the same estimates being 0·98 (95 % CI 0·94, 1·02) for citrus fruit (per fourth), 1·02 (95 % CI 0·98, 1·06) for fruit juice (per fourth), 0·93 (95 % CI 0·89, 0·98) for other fruit (per fourth), 1·05 (95 % CI 0·99, 1·10) for cooked vegetable (per fourth) and 0·86 (95 % CI 0·80, 0·91) for raw vegetable intakes (per fourth). Similar results were obtained for DBP. In conclusion, a high overall intake of fruit, vegetables and fruit juice was inversely associated with SBP, DBP and risk of hypertension, but this differed by FV sub-type, suggesting that the strength of the association between FV sub-types and BP might be related to the type consumed, or to processing or cooking-related factors.
Deprivation in the Midst of Plenty: Citizen Polarization and Political Protest
Authors: Griffin John D. , Kiewiet de Jonge Chad , Velasco-Guachalla Vania Ximena
Published: May 2020

This article elaborates relative deprivation theory to a societal level to argue that political unrest is rooted in the polarization of citizens' grievance judgments, rather than the mean level of societal grievance. Using data from twelve cross-national survey projects, it examines the relationship between citizen polarization and political protest in eighty-four democracies and semi-democracies from 1977 to 2010. The study finds that countries with more polarized citizens are more likely to experience nonviolent protest. Protests are most likely in countries where average citizen grievances are low but citizens are polarized, which is consistent with the elaborated theoretical expectations of relative deprivation theory.
The characteristic signs and symptoms of mania and depression according to Kraepelin circa 1905: a comparison with DSM-III
Authors: Kendler Kenneth S.
Published: May 2020

Although the rise of operationalized diagnostic criteria and the creation of DSM-III were influenced in the USA by a neo-Kraepelinian ‘revival’ of interest in psychiatric nosology, Kraepelin was only a distal influence on the specific diagnostic criteria proposed. The historical origins of the DSM-III criteria for mania and major depression (MD) are traceable back to the 1950s and contain no direct link to Kraepelin's writings. George Dreyfus, a student and assistant to Kraepelin, authored in 1907 a monograph on Involutional Melancholia which reviewed cases seen by Kraepelin in Heidelberg. In this monograph, Dreyfus presents the ‘characteristic’ symptoms for mania and depression ‘as described by Kraepelin.’ This historical finding provides the unprecedented opportunity to examine the resemblance between the criteria proposed for mania and depression in DSM-III, inspired by Kraepelin's nosologic vision, and those specifically suggested by Kraepelin 73 years earlier. Kraepelin's symptoms and signs for mania paralleled seven of the eight DSM-III criteria (except the decreased need for sleep), with two not included in DSM-III (increased mental activity and short bursts of sadness). Kraepelin's signs and symptoms paralleled six of the nine DSM-III criteria for MD, lacking suicidal ideation and changes in appetite/weight and sleep but including obsessions, reduced expressive movements, and decreased mood responsiveness. Although Kraepelin's overall approach to mania and depression emphasized their close inter-relationship in the cyclic course of manic-depressive illness, it is noteworthy Kraepelin's ‘characteristic’ symptoms for mania and depression as described by Dreyfus, bear substantial but incomplete resemblance to the criteria proposed in DSM-III.
Returning to the root: Radical feminist thought and feminist theories of International Relations
Authors: Duriesmith David , Meger Sara
Published: May 2020

Feminist International Relations (IR) theory is haunted by a radical feminist ghost. From Enloe's suggestion that the personal is both political and international, often seen as the foundation of feminist IR, feminist IR scholarship has been built on the intellectual contributions of a body of theory it has long left for dead. Though Enloe's sentiment directly references the Hanisch's radical feminist rallying call, there is little direct engagement with the radical feminist thinkers who popularised the sentiment in IR. Rather, since its inception, the field has been built on radical feminist thought it has left for dead. This has left feminist IR troubled by its radical feminist roots and the conceptual baggage that feminist IR has unreflectively carried from second-wave feminism into its contemporary scholarship. By returning to the roots of radical feminism we believe IR can gain valuable insights regarding the system of sex-class oppression, the central role of heterosexuality in maintaining this system, and the feminist case for revolutionary political action in order to dismantle it.
A blockchain-based decentralized booking system
Authors: Dong Naipeng , Bai Guangdong , Huang Lung-Chen , Lim Edmund Kok Heng , Dong Jin Song
Published: May 2020

Blockchain technology has rapidly emerged as a decentralized trusted network to replace the traditional centralized intermediator. Especially, the smart contracts that are based on blockchain allow users to define the agreed behaviour among them, the execution of which will be enforced by the smart contracts. Based on this, we propose a decentralized booking system that uses the blockchain as the intermediator between hoteliers and travellers. The system enjoys the trustworthiness of blockchain, improves efficiency and reduces the cost of the traditional booking agencies. The design of the system has been formally modelled using the CSP# language and verified using the model checker Process Analysis Toolkit. We have implemented a prototype decentralized booking system based on the Ethereum ecosystem.
Category, process, and recommendation of design in an interactive evolutionary computation interior design experiment: a data-driven study
Authors: Huang Weixin , Su Xia , Wu Mingbo , Yang Lijing
Published: May 2020

Design is a complicated and sophisticated process with numerous existing theories trying to describe it. To verify theories and quantitatively describe the design process, design experiment, and data analysis are crucial and inevitable. However, applying data analysis in the design experiment is tricky and design data is not fully utilized in many aspects. To explore the potential of design experiment data, this paper introduces data-driven research based on an interior design experiment, aiming to reveal the category and process of design by conducting data analysis, visualization, and recommendation. We introduce an interactive evolutionary computation (IEC) design experiment that deals with a simplified interior design task and has already been tested on 230 subjects. Using the data gathered during the experiment, we conduct data analysis and visualization involving methods including Holistic color interval and K-means clustering to show categories and processes in design. Additionally, we train a content-based recommendation system with experiment data to capture user preference and make the IEC system more efficient and intelligent. The analysis and visualization show clear design categories and capture an evident trend towards the final design outcome. The application of the recommendation system brings a prominent improvement to the IEC system. This research shows the great potential of the various data-driven methods in design research.
A novel dual-band dual-polarized shared-aperture antenna with high isolation
Authors: Xu Jiachen , Lan Bozhang , Zhang Jiakai , Guo Chenjiang , Ding Jun
Published: May 2020

This paper presents a novel dual-band (DB) dual-polarized (DP) shared aperture antenna with high isolation by using a combination of microstrip dipoles and dielectric resonator antennas (DRAs) for S and C bands, respectively. In the S band, two sets of proximity coupled stacked microstrip dipoles which crossed at the center are employed to achieve dual-linear polarization (DLP) and obtain desired bandwidth (BW), isolation, and pure polarization. The rectangle DRA with hybrid feed is selected as the C band element for its advantages of small base area and high isolation, and a 2 × 2 array is presented with the “pair-wise” anti-phase feed technique to achieve a low cross-polarized level. Moreover, benefited from the back feed scheme, the proposed antenna has a symmetrical structure and has the potential of expanding into a larger aperture. The proposed antenna has been manufactured and measured, and the results agree well with simulations, which prove the validity of the proposed design.
Calf deep vein thrombosis – clinical relevance, diagnostic approaches and therapeutic options
Authors: Elmi Giovanna , Rinaldi Elisa Rebecca , Domanico Andrea , Aluigi Leonardo
Published: May 2020

Summary. Isolated distal deep vein thromboses (IDDVT) represent up to 50 % of legs deep vein thromboses (DVT). However, since their natural history is to date unknown, the need to diagnose and treat them is a matter of debate. The diagnostic strategy based on the assessment of pre-test probability and D-dimer demonstrated a scarse efficiency for IDDVT. The choice between a proximal and a complete ultrasonographic approach should be guided by the clinical context, the local expertise and the patient characteristics. Randomized and observational studies have analyzed the need of therapy and compared different regimens of anticoagulation, with conflicting results. Systematic reviews and meta-analyses tend to support the usefulness of an anticoagulant treatment, even if the optimal dose and duration are not still defined. A careful stratification of the patient’s profile, taking into account risk factors for proximal extension, recurrence and bleeding should address the therapeutic approach, which must always be discussed with an adequately informed patient. Further studies aimed to clarify the natural history of IDDVT, and to assess safety and efficacy of lower intensity and shorter duration protocols are urgently needed.

We simulated the impact of long‐term changes in the geomagnetic field on the spatial pattern of the Weddell Sea Anomaly (WSA). The Weddell Sea Anomaly, belonging to the region near the tip of the Antarctic Peninsula, Falklands, and surrounding seas, is the best‐known example of ionospheric reversed diurnal cycle. This paper investigates whether and to what extent long‐term changes in the geomagnetic field influence spatial morphology of the WSA. The major concept centers on a normalized density difference index, serving as a measure of difference between dayside and nightside ionospheric density. Through combined analysis of in situ ionospheric electron density data from past mission CHAMP, ongoing ESA mission Swarm, and simulations based on the NCAR TIEGCM model, we examine changes in the spatial pattern of the WSA‐like anomalies, which could be linked to long‐term changes in the geomagnetic field. A series of simulations provides theoretical analysis of changes in the morphology of the WSA on time scales longer than several decades. Numerical analysis shows that from the time when the WSA was discovered (around 1960) till present, maximum of the WSA has migrated by approximately 7° in longitude towards the Pacific Ocean, showing clear westward drift, consistent with temporal evolution of the geomagnetic dipole component.

Target subsurface reservoirs for emerging low‐carbon energy technologies and geologic carbon sequestration typically have low permeability and thus rely heavily on fluid transport through natural and induced fracture networks. Sustainable development of these systems requires deeper understanding of how geochemically mediated deformation impacts fracture microstructure and permeability evolution, particularly with respect to geochemical reactions between pore fluids and the host rock. In this work, a series of triaxial direct shear experiments was designed to evaluate how fractures generated at subsurface conditions respond to penetration of reactive fluids with a focus on the role of mineral precipitation. Calcite‐rich shale cores were directly sheared under 3.5 MPa confining pressure using BaCl2‐rich solutions as a working fluid. Experiments were conducted within an X‐ray computed tomography (xCT) scanner to capture 4‐D evolution of fracture geometry and precipitate growth. Three shear tests evidenced nonuniform precipitation of barium carbonates (BaCO3) along through‐going fractures, where the extent of precipitation increased with increasing calcite content. Precipitates were strongly localized within fracture networks due to mineral, geochemical, and structural heterogeneities and generally concentrated in smaller apertures where rock:water ratios were highest. The combination of elevated fluid saturation and reactive surface area created in freshly activated fractures drove near‐immediate mineral precipitation that led to an 80% permeability reduction and significant flow obstruction in the most reactive core. While most previous studies have focused on mixing‐induced precipitation, this work demonstrates that fluid–rock interactions can trigger precipitation‐induced permeability alterations that can initiate or mitigate risks associated with subsurface energy systems.
The Mechanism of the Freshwater Outflow Through the Ganges‐Brahmaputra‐Meghna Delta

The Ganges‐Brahmaputra‐Meghna (GBM) delta is a major source of freshwater for the Bay of Bengal. The flow through this megadelta is complex because of its large size and numerous river networks, making the region a challenging area for river‐routing models. This study investigates the dynamics of the riverine outflow across the GBM delta and its interaction with the ocean on monthly to seasonal time scales, using a two‐layer model that represents the riverine water and the oceanic water. The model simulates a seasonal increase and decrease of discharge and sea surface height (SSH) at both the main stem and the distributaries. Although discharge through the main stem is driven by that propagating from the upstream, model experiments show that the distributaries are an active region of river‐ocean interactions as a result of a river plume established on the oceanic side of the river mouth. This river plume is induced by river discharge in the presence of the Coriolis force and is associated with an increase in SSH along the coast. Backwater is induced at the river mouth, resulting in convergence and higher SSH in distributaries. The narrow, meandering, and shallow paths of the distributaries enhance the role of friction on the flow from the upstream, making their river mouths more sensitive to oceanic variability. The results of our study demonstrate that river plumes may play a central role in the dynamics of megadelta flow by connecting the dynamics at the main stem and the distributaries with ocean dynamics.
Understanding Spacecraft Trajectories Through Detached Magnetotail Interchange Heads

The kinetic ballooning/interchange instability (BICI) was recently found to produce azimuthally narrow interchange heads extending into the dipole region from a reversed radial gradient of BZ in the near‐Earth magnetotail. In their nonlinear evolution individual heads were predicted to detach from the reversed BZ gradient and grow into transient earthward moving northward magnetic field intensifications (dipolarization fronts; DFs). The distinguished signatures of such fronts would be their oblique propagation and cross‐tail localization due to the finite ky structure of the BICI modes. Simultaneous conjugate observations of DFs by the Time History of Events and Macroscale Interactions during Substorms probes at 11 Earth's radii (RE) downtail and of sudden brightening and growth of individual auroral beads by the all‐sky imagers on the ground have been suggested to be ionospheric signature of detached magnetotail interchange heads (Panov et al., 2019, https://doi.org/10.1029/2019GL083070). Here we compare such DFs with a simulated interchange head during later(detachment)‐stage BICI head development. The comparison reveals similarly structured leading edges and trailing tails in both the observed DFs and the simulated BICI head. We further identify Time History of Events and Macroscale Interactions during Substorms trajectories through the DFs and find that the trajectories were due to oblique (earthward and dawnward) DF propagation. This analysis further supports the idea that BICI indeed releases obliquely propagating azimuthally localized dipolarization fronts in the Earth's magnetotail.
