Livelihood diversification as key to long-term non-migration: evidence from coastal Bangladesh
Authors: Biswas Bangkim , Mallick Bishawjit 
Published: October 2020

AbstractUnderstanding how livelihood diversification contributes to long-term non-migration decisions of people at risks is innovative and timely in the context of future climate change adaptation planning. This study particularly examines this question and explores how and to what extent livelihood diversification in the face of climate change can support long-term non-migration for people living in the southwest coastal region of Bangladesh. We employed a cluster random sampling method to select the respondents and interviewed a total of 183 households by using a structured questionnaire. Analysis indicates that the tendency of livelihood diversification based on shrimp-farming has been intensified in recent years as the land use pattern also changed due to the frequent occurrence of environmental hazards. The Poisson regression model states that belonging to a religious minority and shrimp farming determines the extent of livelihood diversification, i.e., if the person belongs to a minority religion and possesses a shrimp-farm they will have more diversified sources of income compared to others living in the society. Moreover, therefore, one in every three households in these studied communities’ practices seasonal migration as an alternative livelihood strategy so that their family can stay put. The outcome of this study motivates the government and non-government organizations to take policies and programs in a direction that may reduce the dependency on seasonal migration and introduce locally adoptable diversified employment opportunities.
Threshold concepts and certainty: a critical analysis of ‘troublesomeness’
Authors: Stopford Richard 
Published: October 2020

AbstractThe threshold concept framework is a key contemporary theory in pedagogy. The core idea is that ‘threshold concepts’ are distinctively ‘troublesome’ for students and act as gatekeepers to their disciplines. No doubt the theory is compelling because there is surely something right about this. Student difficulty with conceptual material is familiar to all teaching practitioners. Furthermore, to avoid rote levels of understanding, mastery of discipline-specific conceptual material is key. However, TCF has struggled to articulate key dimensions of its theory: it is without a methodology for identifying threshold concepts. It has also faltered in explaining how student difficulty is a function of difficulties endemic to the concepts, rather than as a contingent phenomenon about individual students.I offer a novel way to think about identifying threshold concepts, and for theorising student difficulties which may arise from those concepts. I argue that there is an ‘existential’ kind of certainty which acts as a framework within which epistemic activities take place. Disciplines which theorise concepts in ways that clash with students’ existential certainties are candidates for threshold concepts and may generate ‘objective’ difficulties for students. As much as I think theorising existential certainty helps TCF overcome theoretical challenges, it would require revisions to the way that it is currently being theorised and applied. I also believe that even without attachments to TCF, ‘existential certainty’ is a real phenomenon, shaping the very possibilities of student experience, and which any pedagogical theory should be aware of.
Explicit Solution of the Generalised Langevin Equation
Authors: Di Terlizzi Ivan , Ritort Felix , Baiesi Marco 
Published: October 2020

AbstractGenerating an initial condition for a Langevin equation with memory is a non trivial issue. We introduce a generalisation of the Laplace transform as a useful tool for solving this problem, in which a limit procedure may send the extension of memory effects to arbitrary times in the past. This method allows us to compute average position, work, their variances and the entropy production rate of a particle dragged in a complex fluid by an harmonic potential, which could represent the effect of moving optical tweezers. For initial conditions in equilibrium we generalise the results by van Zon and Cohen, finding the variance of the work for generic protocols of the trap. In addition, we study a particle dragged for a long time captured in an optical trap with constant velocity in a steady state. Our formulas open the door to thermodynamic uncertainty relations in systems with memory.
The Role of Classmates’ Modeling and Reinforcement in Adolescents’ Perceived Classroom Peer Context
Authors: Mertens Esther C. A. , Deković Maja , Van Londen Monique , Reitz Ellen 
Published: October 2020

AbstractExperiences with classmates can affect adolescents’ academic, emotional, and social development. The aim was to examine whether changes in classmates’ modeling and reinforcement, induced by an intervention, affected changes in adolescents’ perceived classroom peer context and whether these associations were moderated by dyadic mutuality. Questionnaires and observations were used in a sample of 7th Grade students (N = 152; Mage = 12.37; 53.8% boys). Generally, changes in classmates’ modeling and reinforcement were unrelated to adolescents’ perceived classroom peer context, except for classmates’ prosocial modeling. Increases in prosocial modeling were related to decreases in victimization, especially for dyads with high levels of mutuality. The results suggest that classmates’ prosocial modeling may be more important for the perceived classroom peer context than classmates’ deviant modeling.
Departures and returns: cultural identities, historical traumas and personal paths in Susan R. Suleiman’s Budapest Diary
Authors: Z. Varga Zoltán 
Published: October 2020

AbstractThis paper studiesBudapest Diary(1996), a cross-genre autobiographical work by Susan Suleiman, a renowned Hungarian-born scholar in comparative literature. Suleiman’s life writing offers particularly interesting reading possibilities; it allows us to study recent theoretical issues from historical traumas to multicultural and multi-linguistic identity constructions. My paper focuses on how Suleiman examines her past as a literary critic and expert on the modern novel, how her theoretical background as a comparatist formed and fashioned her autobiographical project. A close reading of herBudapest Diaryreveals not only the generic patterns, the narrative and poetical means borrowed from her literary formation but also theories that enable the author to analyze her past, the social, cultural and historical determinations manifested in her life story. My interpretation devotes special attention to the image of Eastern-Europe developed in Suleiman’s autobiographical work. I analyze the way the work of the author, who returned to her homeland as an adult, seeks not only to find the reasons for burying the past burdened with collective historical traumas, but also tries to discover the regional components of identity, of the cultural otherness of East-Central Europe. The paper aims to show how collective and personal stakes are intertwined in the difficult process of reacquiring her Hungarian past in the light of her relationship with her parents (especially with her mother), and that of the history of Jewish people in Eastern Europe during the 20thcentury.
Controlling transient gas flow in real-world pipeline intersection areas
Authors: Hennings Felix , Anderson Lovis , Hoppmann-Baum Kai , Turner Mark , Koch Thorsten 
Published: October 2020

AbstractCompressor stations are the heart of every high-pressure gas transport network. Located at intersection areas of the network, they are contained in huge complex plants, where they are in combination with valves and regulators responsible for routing and pushing the gas through the network. Due to their complexity and lack of data compressor stations are usually dealt with in the scientific literature in a highly simplified and idealized manner. As part of an ongoing project with one of Germany’s largest transmission system operators to develop a decision support system for their dispatching center, we investigated how to automatize the control of compressor stations. Each station has to be in a particular configuration, leading in combination with the other nearby elements to a discrete set of up to 2000 possible feasible operation modes in the intersection area. Since the desired performance of the station changes over time, the configuration of the station has to adapt. Our goal is to minimize the necessary changes in the overall operation modes and related elements over time while fulfilling a preset performance envelope or demand scenario. This article describes the chosen model and the implemented mixed-integer programming based algorithms to tackle this challenge. By presenting extensive computational results on real-world data, we demonstrate the performance of our approach.
The prospects of emotional dogmatism
Authors: Harrison Eilidh 
Published: October 2020

AbstractThe idea that emotional experience is capable of lending immediate and defeasible justification to evaluative belief has been amassing significant support in recent years. The proposal that it is myanger, say, that justifies my belief that I’ve been wronged putatively provides us with an intuitive and naturalised explanation as to how we receive epistemic justification for a rich catalogue of our evaluative beliefs. However, despite the fact that this justificatory thesis of emotion is fundamentally an epistemological proposal, comparatively little has been done to explicitly isolatewhat it isabout emotions that bestows them with justificatory ability. The purpose of this paper is to provide a novel and thorough analysis into the prospects of phenomenology-based—ordogmatist—views of emotional justification. By surveying and rejecting various instantiations of the emotional dogmatist view, I endeavour to provide an inductive case for the conclusion that emotional phenomenology cannot be the seat of the emotions’ power to immediately justify evaluative belief.
AIP variant causing familial prolactinoma

Published: October 2020

AbstractPathogenic variants in the aryl hydrocarbon receptor-interacting protein (AIP) gene are increasingly recognised as a cause of familial isolated pituitary adenoma. AIP-associated tumours are most commonly growth hormone (GH) producing. In our cohort of 175 AIP mutation positive patients representing 93 kindreds, 139 (79%) have GH excess, 19 have prolactinoma (17 familial and 2 sporadic cases) and out of the 17 clinically non-functioning tumours 4 were subsequently operated and found to be GH or GH & prolactin immunopositive adenoma. Here we report a family with an AIP variant, in which multiple family members are affected by prolactinoma, but none with GH excess. To our knowledge this is the first reported family with an AIP pathogenic variant to be affected solely by prolactinoma. These data suggest that prolactinoma families represent a small subset of AIP mutation positive kindreds, and similar to young-onset sporadic prolactinomas, AIP screening would be indicated.
Writing Philosophy from the Periphery: Lixing as Foundational Empty Signifier in Tang Junyi’s Cultural Consciousness and Moral Reason
Authors: Major Philippe 
Published: October 2020

AbstractThis article adopts Ernesto Laclau’s notion of empty signifier to discuss Tang Junyi’s uses of the concept oflixing(‘reason’ or ‘rationality’) in his seminal workCultural Consciousness and Moral Reason(文化意識與道德理性; 1958). My dual goal, in doing so, is to bring to light the relations of power constitutive of the text’s discourse onlixingand relate them to the problematic of writing philosophy from the periphery. I argue that in this work,lixing’s dual referents—as a translation of ‘reason’ and as denoting a Neo-Confucian faculty to intuit moral truths—allow Tang to inscribe himself in a philosophical field designed to exclude non-Western philosophies, while at the same time enabling him to symbolically relegate Euro-American philosophy to a peripheral position by filling in the notion oflixingwith a content that legitimizes his own agenda. Tang could thus authorize his Confucian metaphysics by presenting it as the true content oflixing, understood not only as a universal faculty enabling humanity’s access to all that is universal, but also as a condition sine qua non of for one’s inclusion in the philosophical game. By attempting to co-opt the empty signifier (lixing/reason) for his own purposes, I argue Tang employs one of two possible strategies that can be adopted by those situated at the periphery in order to oppose the hegemon; one that leaves the structure of power relations intact but working in favor of the periphery.

AbstractCarbon nanomaterials offer excellent prospects as therapeutic agents, and among them, graphene quantum dots (GQDs) have gained considerable interest thanks to their aqueous solubility and intrinsic fluorescence, which enable their possible use in theranostic approaches, if their biocompatibility and favorable pharmacokinetic are confirmed. We prepared ultra-small GQDs using an alternative, reproducible, top-down synthesis starting from graphene oxide with a nearly 100% conversion. The materials were tested to assess their safety, demonstrating good biocompatibility and ability in passing the ultrafiltration barrier using an in vitro model. This leads to renal excretion without affecting the kidneys. Moreover, we studied the GQDs in vivo biodistribution confirming their efficient renal clearance, and we demonstrated that the internalization mechanism into podocytes is caveolae-mediated. Therefore, considering the reported characteristics, it appears possible to vehiculate compounds to kidneys by means of GQDs, overcoming problems related to lysosomal degradation.
“Don’t Get Distracted!”: The Role of Social Robots’ Interaction Style on Users’ Cognitive Performance, Acceptance, and Non-Compliant Behavior

Published: October 2020

AbstractSocial robots are developed to provide companionship and assistance in the daily life of the children, older, and disable people but also have great potential as educational technology by facilitating learning. In these application areas, a social robot can take the role of a coach by training and assisting individuals also in cognitive tasks. Since a robot’s interaction style affects users’ trust and acceptance, customizing its behavior to the proposed tasks could, potentially, have an impact on the users’ performance. To investigate these phenomena, we enrolled sixty volunteers and endowed a social robot with a friendly and an authoritarian interaction style. The aim was to explore whether and how the robot’s interaction style could enhance users’ cognitive performance during a psychometric evaluation. The results showed that the authoritarian interaction style seems to be more appropriate to improve the performance when the tasks require high cognitive demands. These differences in cognitive performance between the groups did not depend on users’ intrinsic characteristics, such as gender and personality traits. Nevertheless, in the authoritarian condition, participants’ cognitive performance was related to their trust and the acceptance of the technology. Finally, we found that users’ non-compliant behavior was not related to their personality traits. This finding indirectly supports the role of the robot’s interaction style in influencing the compliance behavior of the users.

Published: October 2020

AbstractTrisomy 21 is the most common aneuploidy in liveborn infants. Most of the soft markers for trisomy 21 are non-specific and transient. We present 2 cases which had abnormalities which are very rarely associated with Down’s syndrome. In the first case, the patient had bilateral congenital cataract along with an absent nasal bone. In the second case, the patient had severe asymmetric fetal growth restriction at 20 weeks with other multi-system abnormalities. With detailed ultrasound scanning and thorough investigation, we could diagnose trisomy 21 even with such unusual presentations.
Activity patterns in a feline assemblage in south-west Mexico, and their relationship with prey species
Authors: Hernández-Sánchez Alejandro , Santos-Moreno Antonio 
Published: October 2020

AbstractSeveral species of neotropical felines are morphologically and ecologically similar, and are sympatric along large areas of their distribution. This requires mechanisms to allow their coexistence, such as temporal segregation of their activities. The aim of this study was to evaluate the relation between activity patterns of felines and their prey using camera trapping data and their seasonal variation in two tropical environments in south-western Mexico. ExceptingPuma concolor, activity patterns for each feline species did not differ significantly between seasons nor between vegetation types. Activity patterns did not differ significantly between species of similar size: mid-sized species had high activity pattern overlaps in the medium forest while large-sized species overlapped to a lesser extent in the cloud forest.Leopardus wiediidiffered from large-sized predators in its activity patterns. We recorded a relatively high temporal overlap between felines and their main prey species, particularly in the periods of maximum activity. We found no evidence of temporal segregation between the felines of the Sierra Norte region of Oaxaca and we suggest their coexistence is mediated by the selection of prey with different activity patterns.
Information brokerage in Caribbean coral reef governance networks

Published: October 2020

SummaryPoor connectivity between diverse resource users and complex wider governance networks is a challenge in environmental governance. Organizations that ‘broker’ interactions among these relationships are expected to improve governance outcomes. Here, we used semi-structured interviews and social network analysis to identify actors in positions to broker coral reef-related information to and from resource users and to assess the performance of these brokers. Representatives (n = 262) of actor groups were interviewed, including local and national government, non-governmental organizations (NGOs), community organizations and resource user groups from 12 communities across four Caribbean countries, to map information-sharing networks and to identify brokers. Broker performance was assessed through separate interviews with coral reef resource users (n = 545). The findings show that marine NGOs were the highest-functioning brokers. Where such local-level organizations were absent, government agencies in reef management roles acted as brokers, but their performance was lower. Actors in brokerage positions did not always effectively share information, with broker performance being positively correlated with network brokerage scores. The results further our understanding of the roles of brokers in different governance contexts. Identifying those in brokerage positions and supporting their roles in connecting local resource users to wider governance networks could encourage functional brokerage and enhance reef management outcomes.

AbstractObjective:To examine the impact of front-of-package (FOP) labels on perceived healthfulness, purchasing intentions and understanding of common FOP systems.DesignA parallel, open-label design randomised participants to different FOP labelling conditions: ‘high in’ warning labels (WL), multiple traffic light labelling (TLL), health star ratings (HSR) (all displayed per serving) or control with no interpretive FOP labelling. Participants completed a brief educational session via a smartphone application and two experimental tasks. In Task 1, participants viewed healthy or unhealthy versions of four products and rated healthiness and purchasing intention on a seven-point Likert-type scale. In Task 2, participants ranked three sets of five products from healthiest to least healthy.SettingOnline commercial panel.ParticipantsCanadian residents ≥ 18 years who were involved in household grocery shopping, owned a smartphone and met minimum screen requirements.ResultsData from 1997 participants (n 500/condition) were analysed. Task 1: across most product categories, the TLL and HSR increased perceived healthiness of healthier products. All FOP systems decreased perceived healthiness of less healthy products. Similar, albeit dampened, effects were seen regarding purchasing intentions. Task 2: participants performed best in the HSR, followed by the TLL, WL and control conditions. Lower health literacy was associated with higher perceived healthiness and purchasing intentions and poorer ranking task performance across all conditions.ConclusionsAll FOP labelling systems, after a brief educational session, improved task performance across a wide spectrum of foods. This effect differed depending on the nutritional quality of the products and the information communicated on labels.Trial Registration: NCT03290118.
