We develop a new technique for proving concentration inequalities which relate between the variance and influences of Boolean functions. Using this technique, we 1. Settle a conjecture of Talagrand [Tal97] proving that $$\int_{\left\{ -1,1\right\} ^{n}}\sqrt{h_{f}\left(x\right)}d\mu\geq C\cdot\mathrm{var}\left(f\right)\cdot\left(\log\left(\frac{1}{\sum\mathrm{Inf}_{i}^{2}\left(f\right)}\right)\right)^{1/2},$$ where $h_{f}\left(x\right)$ is the number of edges at $x$ along which $f$ changes its value, and $\mathrm{Inf}_{i}\left(f\right)$ is the influence of the $i$-th coordinate. 2. Strengthen several classical inequalities concerning the influences of a Boolean function, showing that near-maximizers must have large vertex boundaries. An inequality due to Talagrand states that for a Boolean function $f$, $\mathrm{var}\left(f\right)\leq C\sum_{i=1}^{n}\frac{\mathrm{Inf}_{i}\left(f\right)}{1+\log\left(1/\mathrm{Inf}_{i}\left(f\right)\right)}$. We give a lower bound for the size of the vertex boundary of functions saturating this inequality. As a corollary, we show that for sets that satisfy the edge-isoperimetric inequality or the Kahn-Kalai-Linial inequality up to a constant, a constant proportion of the mass is in the inner vertex boundary. 3. Improve a quantitative relation between influences and noise stability given by Keller and Kindler. Our proofs rely on techniques based on stochastic calculus, and bypass the use of hypercontractivity common to previous proofs., Comment: 48 pages, 2 figures

Impartial selection has recently received much attention within the multi-agent systems community. The task is, given a directed graph representing nominations to the members of a community by other members, to select the member with the highest number of nominations. This seemingly trivial goal becomes challenging when there is an additional impartiality constraint, requiring that no single member can influence her chance of being selected. Recent progress has identified impartial selection rules with optimal approximation ratios. Moreover, it was noted that worst-case instances are graphs with few vertices. Motivated by this fact, we propose the study of additive approximation, the difference between the highest number of nominations and the number of nominations of the selected member, as an alternative measure of the quality of impartial selection. Our positive results include two randomized impartial selection mechanisms which have additive approximation guarantees of $\Theta(\sqrt{n})$ and $\Theta(n^{2/3}\ln^{1/3}n)$ for the two most studied models in the literature, where $n$ denotes the community size. We complement our positive results by providing negative results for various cases. First, we provide a characterization for the interesting class of strong sample mechanisms, which allows us to obtain lower bounds of $n-2$, and of $\Omega(\sqrt{n})$ for their deterministic and randomized variants respectively. Finally, we present a general lower bound of $2$ for all deterministic impartial mechanisms., Comment: 18 pages, 7 figures. A preliminary version appeared in SAGT '19.

It is of folkloric belief that the security of classical cryptographic protocols is automatically broken if the Adversary is allowed to perform superposition queries and the honest players forced to perform actions coherently on quantum states. Another widely held intuition is that enforcing measurements on the exchanged messages is enough to protect protocols from these attacks. However, the reality is much more complex. Security models dealing with superposition attacks only consider unconditional security. Conversely, security models considering computational security assume that all supposedly classical messages are measured, which forbids by construction the analysis of superposition attacks. Boneh and Zhandry have started to study the quantum computational security for classical primitives in their seminal work at Crypto'13, but only in the single-party setting. To the best of our knowledge, an equivalent model in the multiparty setting is still missing. In this work, we propose the first computational security model considering superposition attacks for multiparty protocols. We show that our new security model is satisfiable by proving the security of the well-known One-Time-Pad protocol and give an attack on a variant of the equally reputable Yao Protocol for Secure Two-Party Computations. The post-mortem of this attack reveals the precise points of failure, yielding highly counter-intuitive results: Adding extra classical communication, which is harmless for classical security, can make the protocol become subject to superposition attacks. We use this newly imparted knowledge to construct the first concrete protocol for Secure Two-Party Computation that is resistant to superposition attacks. Our results show that there is no straightforward answer to provide for either the vulnerabilities of classical protocols to superposition attacks or the adapted countermeasures., 46 pages

Market makers choose and design market rules to serve certain objectives, such as to maximize revenue from the sales in the case of a single seller and multiple buyers. Given such rules, market participants play against each other to maximize their utility function values on goods acquired, possibly by hiding or misrepresenting their information needed in the implementation of market rules. Today’s Internet economy has changed the information collection process and may make some of the assumptions of market rule implementation obsolete. Here we make a fresh review of works on this challenge on the Internet where new economic systems operate.

This paper uses a quantile fixed-effect panel data approach to investigate how environmental policy stringency affects CO2 emissions in a set of 32 OECD countries from 1990 to 2015. This approach allows us to identify the asymmetric impact of policy stringency on emissions, considering the emission level recorded in each analysed country. More precisely, we posit that the effectiveness of environmental regulations and policies is influenced by the air pollution level. Our results show that an increase in policy stringency has a negative impact on emissions. As a new contribution, we show that environmental stringency has a more powerful impact in the countries with lower level of carbon emissions. This result is also recorded for the subset of EU member countries of the OECD. Moreover, we show that policy stringency measures only become effective after the implementation of the Kyoto agreement. Finally, the policy stringency effect is stronger for EU countries at high risk of missing the 20-20-20 target in terms of greenhouse gas emissions.JEL codes: Q43, Q56, F21

Altres ajuts: Centre of Excellence for Children and Families over the Life Course, Australian Research Council (AU); https://doi.org/10.13039/501100001659 (LE 3612/2-1 CE140100027) ; Deutsche Forschungsgemeinschaft ; CERCA Programme/Generalitat de Catalunya Considering soaring wealth inequalities in older age, this research addresses the relationship between family life courses and widening wealth diferences between individuals as they age. We holistically examine how childbearing and marital histories are associated with personal wealth at ages 50-59 for Western Germans born between 1943 and 1967. We propose that deviations from culturally and institutionally-supported family patterns, or the stratifed access to them, associate with diferential wealth accumulation over time and can explain wealth inequalities at older ages. Using longitudinal data from the German Socio-Economic Panel Study (SOEP, v34, waves 2002-2017), we frst identifed typical family trajectory patterns between ages 16 and 50 with multichannel sequence analysis and cluster analysis. We then modelled personal wealth ranks at ages 50-59 as a function of family patterns. Results showed that deviations from the standard family pattern (i.e. stable marriage with, on average, two children) were mostly associated with lower wealth ranks at older age, controlling for childhood characteristics that partly predict selection into family patterns and baseline wealth. We found higher wealth penalties for greater deviation and lower penalties for moderate deviation from the standard family pattern. Addressing entire family trajectories, our research extended and nuanced our knowledge of the role of earlier family behaviour for later economic wellbeing. By using personal-level rather than household-level wealth data, we were able to identify substantial gender diferences in the study associations. Our research also recognised the importance of combining marital and childbearing histories to assess wealth inequalities.

Animals and humans have multiple memory systems. While both black-capped chickadees (Poecile atricapillus) and dark-eyed juncos (Junco hyemalis) are under selective pressure to remember reliable long-term spatial locations (habit memory), chickadees must additionally quickly form and rapidly update spatial memory for unique cache sites (one-trial memory). We conducted a series of three experiments in which we assessed the degree to which habit and one-trial memory were expressed in both species as a function of training context. In Experiment 1, birds failed to demonstrate habits on probe trials after being trained in the context of a biased Match-to-Sample task in which the same high-frequency target was always correct. In Experiment 2, habit strongly controlled performance when habits were learned as Discriminations, defining a specific training context. In Experiment 3, context no longer defined when to express habits and habit and one-trial memory competed for control of behavior. Across all experiments, birds preferentially used the memory system at test that was consistent with the context in which it was acquired. Although the memory adaptations that allow chickadees to successfully recover cached food might predispose them to favor one-trial memory, we found no species differences in the weighting of habit and one-trial memory. In the experiments here, context was a powerful factor controlling the interaction of memory systems.

The growing polarization of our societies and economies has been extensively studied in various disciplines and is subject to public controversy. Yet, measuring polarization is hampered by the discrepancy between how polarization is conceptualized and measured. For instance, the notion of group, especially groups that are identified based on similarities between individuals, is key to conceptualizing polarization but is usually neglected when measuring polarization. To address the issue, this paper presents a new polarization measurement based on a grouping method called “Equal Size Binary Grouping” (ESBG) for both uni- and multi-dimensional discrete data, which satisfies a range of desired properties. Inspired by techniques of clustering, ESBG divides the population into two groups of equal sizes based on similarities between individuals, while overcoming certain theoretical and practical problems afflicting other grouping methods, such as discontinuity and contradiction of reasoning. Our new polarization measurement and the grouping method are illustrated by applying them to a two-dimensional synthetic data set. By means of a so-called “squeezing-and-moving” framework, we show that our measurement is closely related to bipolarization and could help stimulate further empirical research.

Legal wiretapping has gained importance in law enforcement along with the development of information and communication technology. Understanding the language of intercepted persons is essential for the success of a police investigation. Hence, intercept interpreters, as we suggest calling them in this article, are hired. Little is known about this specific work at the interface between language and law. With this article, we desire to contribute to closing this gap by focussing particularly on the translational activity. Our study identifies a fragmented field of research due to the difficulty in accessing workers in this specific field who interpret in a highly confidential phase of criminal investigations. The findings, which are drawn from scarce studies and our empirical data derived from an online questionnaire for a pilot study in Switzerland, demonstrate the wide range of the performed activity intercept interpreting. This article is the first to present translational activity from the perspective of intercept interpreters. The activity differs in many ways from interpretation in court hearings or police interviews. Hence, we suggest categorising interlingual intercept interpretation as a translational activity sui generis and—since previous research has not done justice to the ethical and deontological questions that intercept interpretation raises—advocate for further transdisciplinary research in this field of translation.

Limited empirical evidence is available regarding the uptake and effectiveness of school-based mental health and wellbeing programs implemented in Australian schools. This study aimed to characterise the delivery of programs in primary (elementary) schools across New South Wales, Australia, and to assess this information against published ratings of program effectiveness. Delivery of programs in four health-promoting domains—creating a positive school community; teaching social and emotional skills; engaging the parent community; and supporting students experiencing mental health difficulties—were reported by 597 school principals/leaders via online survey. Although three quarters of principals reported implementing at least one program, many of these programs were supported by little or no evidence of effectiveness. There was also variability in the use of evidence-based programs across the four domains. Findings indicate a need to provide educators with improved support to identify, implement, and evaluate effective evidenced-based programs that promote student mental health.

The ability to infer intentions from observed behavior and predict actions based on this inference, known as intention attribution (IA), has been hypothesized to be impaired in individuals with autism spectrum disorder (ASD). The underlying neural processes, however, have not been conclusively determined. The aim of this study was to examine the neural signature of IA in children and adolescents with ASD, and to elucidate potential links to contextual updating processes using electroencephalography. Results did not indicate that IA or early contextual updating was impaired in ASD. However, there was evidence of aberrant processing of expectation violations in ASD, particularly if the expectation was based on IA. Results are discussed within the context of impaired predictive coding in ASD.

We propose a novel risk measure that is built on comparing high-frequency time-varying volatility and low-frequency return spillover estimates. This measure permits to identify the markets that are epidemic in their complex interdependence. We conjecture that initially a highly volatile market experiences episodes of risk transmission, but only later absorbs risk and becomes an epidemic market. Moreover, we can detect newly emerging ‘contagion’ in the system. We examine the behaviour of 30 global equity markets and compare spillover measures, which encapsulate many large and small crises episodes. Instead of relying on ex post crisis information, our model identifies crises periods. An important implication of the proposed approach is that highly interrelated markets, such as China, are less likely to transmit a global economic crisis under the current interdependence setting.

I argue that virtue reliabilism and virtue responsibilism are complementary. They do not give competing accounts of epistemic virtue. Rather they explain the excellent functioning of different parts of our cognitive apparatus. Reliabilist virtue designates the excellent functioning of fast and context-specific Type 1 cognitive processes, while responsibilist virtue means an excellent functioning of effortful and reflective Type 2 cognitive processes. This account unifies reliabilist and responsibilist virtue theory. But the virtues are not unified by designating some epistemic norm that both aim at. Instead, I unify them through their cognitive foundations. Because Type 1 and Type 2 cognition are complementary, reliabilist and responsibilist virtues are complementary. Thereby, this dual-process theory of epistemic virtue gives a naturalised account of virtues as well as an explanation of how reliabilism and responsibilism relate. This approach offers a solution for both the generality problem and the situationist challenge to virtue epistemology; additionally it preserves the epistemological autonomy of each virtue type.

International audience; In light of the ongoing agrobiodiversity erosion process, we delve into the history of crop genetic resources governing instruments to show how the international agro- biodiversity regime has evolved from a limited appreciation of the contribution of farmers/peasants to a broader recognition of the critical role indigenous peoples, local communities, and farmers play in shaping and cultivating agrobiodiversity. We explore the genesis and development of various international soft and hard law instruments that make up this international agrobiodiversity regime. We focus on the period stretching from the 1983 Food and Agriculture Organization’s Interna- tional Undertaking on Plant Genetic Resources, to the 2018 United Nations Dec- laration on the Rights of Peasants and Other People Working in Rural Areas. The reflexion is organised around three lines. First, we show the advent of the concept of “farmers’ rights” and underline its initial indeterminacy. Then, we move on to the issue of farmers/peasants in the aftermath of the Convention on Biological Diversity and analyse the crystallisation of debates around incentivising and driving on-farm maintenance of crop genetic resources. Finally, we conclude by outlining the new framework offered by biocultural approaches to rethink peasants’ rights.

Die Zahl der Krebskranken und -uberlebenden in Deutschland wird aufgrund des demografischen Wandels und der Fortschritte in der Medizin zunehmen. Im vorliegenden Beitrag wird die Epidemiologie von Krebs in hohem Alter beschrieben und auf folgende Fragen eingegangen: Welche Krebserkrankungen sind die haufigsten und wie stellen sich die Prognose und die zeitliche Entwicklung von Inzidenz und Mortalitat bei Alteren dar? Daten zu Inzidenz, Mortalitat und relativem 5‑Jahres-Uberleben wurden der interaktiven Datenbank des Zentrums fur Krebsregisterdaten entnommen; sie umfassen die Jahre 1999–2016. Berichtet wird uber Fallzahlen, altersgruppenspezifische Raten, relative Anteile fur Krebs gesamt sowie die funf haufigsten Diagnosegruppen, differenziert nach Geschlecht und nach vier Altersgruppen (AG; 40–64, 65–74, 75–84, 85+ Jahre; Uberleben: 45–54, 55–64, 65–74, 75+ Jahre). Rund 38 % aller Krebsneuerkrankungen bei Frauen und rund 37 % bei Mannern treten in der Gruppe der Hoch- und Hochstbetagten (AG 75–84 und 85+ Jahre) auf. Vorherrschende Krebserkrankungen in den oberen Altersgruppen sind Brust- bzw. Prostata‑, Darm‑, Lungen‑, Gebarmutterkorper‑, Bauchspeicheldrusen‑, Harnblasen- und Magenkrebs. Die Prognose ist abhangig von der Art der Krebserkrankung, Geschlecht und Alter bei Diagnosestellung und streut in einem weiten Bereich (relatives 5‑Jahres-Uberleben 90 % u. a. bei Brust‑, Prostatakrebs, malignem Melanom der Haut). Nicht nur die Anzahl der Krebskranken und -uberlebenden wird zukunftig steigen, sondern auch die Bedarfe im Bereich der Primarversorgung und Tertiarpravention werden zunehmen.

Some women athletes have expressed the perceived need to be self-critical to flourish in sport; however, women athletes with higher self-compassion levels tend to have greater psychological flourishing. Athletes’ baseline levels of self-compassion (i.e., having a kind, connected, and balanced self-attitude when experiencing hardships) may be key to psychologically flourish in sport during the competitive season, yet this has not been examined over time. The purpose of this study was to examine whether women athletes’ self-compassion at the start of their competitive season predicted variance beyond self-criticism in psychological flourishing at the end of their season. Competitive women athletes (N = 78; Mage = 22.97 years) in Canada completed an online survey at the start and end of their competitive season. Self-report measures included athlete versions of self-compassion and self-criticism scales, and sport-specific proxy measures of six components of psychological flourishing (autonomy, mastery, growth, positive relatedness, purpose, and self-acceptance). Hierarchical regression analyses indicated that early season self-compassion explained 6% and 9% variance beyond self-criticism on end-of-season purpose and self-acceptance, respectively. The full models accounted for 12% and 29% of the variance. The results suggest that self-compassion may have an enduring and adaptive contribution to some dimensions of psychological flourishing in sport. Intentionally implementing self-compassion interventions at the start of women athletes’ competitive seasons may have merit on the trajectory of their well-being.

Collaborative problem solving (CPS) is widely recognized as a prominent 21st-century skill to be mastered. Until recently, research on CPS has often focused on problem solution by the individual; the interest in investigating how the theorized problem-solving constructs function as broader social units, such as pairs or small groups, is relatively recent. Capturing the complexity of CPS processes in group-level interaction is challenging. Therefore, a method of analysis capturing various layers of CPS was developed that aimed for a deeper understanding of CPS as a small-group enactment. In the study, small groups of teacher education students worked on two variations of open-ended CPS tasks—a technology-enhanced task and a task using physical objects. The method, relying on video data, encompassed triangulation of analysis methods and combined the following: (a) directed content analysis of the actualized CPS in groups, (b) process analysis and visualizations, and (c) qualitative cases. Content analysis did not show a large variation in how CPS was actualized in the groups or tasks for either case, whereas process analysis revealed both group- and task-related differences in accordance with the interchange of CPS elements. The qualitative cases exemplified the interaction diversity in the quality of coordination and students’ equal participation in groups. It was concluded that combining different methods gives access to various layers of CPS; moreover, it can contribute to a deeper articulation of the CPS as a group-level construct, providing divergent ways to understand CPS in this context.

In this paper we propose to study the dynamics of financial contagion between the credit default swap (CDS) and the sovereign bond markets through effective transfer entropy, a model-free methodology which enables to overcome the required hypotheses of classical price discovery measures in the statistical and econometric literature, without being restricted to linear dynamics. By means of effective transfer entropy we correct for small sample biases which affect the traditional Shannon transfer entropy, as well as we are able to conduct inference on the estimated directional information flows. In our empirical application, we analyze the CDS and bond market data for eight countries of the European Union, and aim to discover which of the two assets is faster at incorporating the information on the credit risk of the underlying sovereign. Our results show a clear and statistically significant prominence of the bond market for pricing the sovereign credit risk, especially during the crisis period. During the post-crisis period, instead, a few countries behave dissimilarly from the others, in particular Spain and the Netherlands.

With innovation as a third mission of universities, governments around the world have competitive funding schemes to support university-industry collaboration. Little is known about the effectiveness of these schemes compared to traditional competitive funding programs in increasing commercially valuable research outputs from universities. We explore whether university-industry targeted schemes are more effective by comparing two Australian funding programs that share the processes of how funds are awarded—one with a requirement of university-industry collaboration, the other traditional, not requiring collaboration. We use patenting activity as our measure of commercially valuable research outputs. We find that university inventors awarded university-industry targeted grants have greater patent activity compared to those awarded non-targeted grants. Analysing the dynamics, we find the effect is rather short lived, with an increase in patent activity in the year of award of grant not persisting in subsequent years. We find a similar effect on a university level. We also find that the number of new patent applications, but not patents granted, is greatest when universities achieve a mix of both types of funding.

A number of perceptual (exteroceptive and proprioceptive) illusions present problems for predictive processing accounts. In this chapter we’ll review explanations of the Müller-Lyer Illusion (MLI), the Rubber Hand Illusion (RHI) and the Alien Hand Illusion (AHI) based on the idea of Prediction Error Minimization (PEM), and show why they fail. In spite of the relatively open communicative processes which, on many accounts, are posited between hierarchical levels of the cognitive system in order to facilitate the minimization of prediction errors, perceptual illusions seemingly allow prediction errors to rule. Even if, at the top, we have reliable and secure knowledge that the lines in the MLI are equal, or that the rubber hand in the RHI is not our hand, the system seems unable to correct for sensory errors that form the illusion. We argue that the standard PEM explanation based on a short-circuiting principle doesn’t work. This is the idea that where there are general statistical regularities in the environment there is a kind of short circuiting such that relevant priors are relegated to lower-level processing so that information from higher levels is not exchanged (Ogilvie and Carruthers, Review of Philosophy and Psychology 7:721–742, 2016), or is not as precise as it should be (Hohwy, The Predictive Mind, Oxford University Press, Oxford, 2013). Such solutions (without convincing explanation) violate the idea of open communication and/or they over-discount the reliable and secure knowledge that is in the system. We propose an alternative, 4E (embodied, embedded, extended, enactive) solution. We argue that PEM fails to take into account the ‘structural resistance’ introduced by material and cultural factors in the broader cognitive system.

Youths’ experiences in seeking and accessing help for mental health problems can have pervasive and lasting effects on personal and interpersonal functioning. In particular, youth who experience validating experiences presumably persevere in seeking help and generally have positive treatment outcomes, whereas youth who experience invalidation are also likely to experience, at least in the short term, ruptures in therapeutic relationships, shame, and reluctance to seek services. The goal of the current study was to expand on previous research assessing youths’ interactions with mental health providers, allied professionals, family members, and peers, with a focus on subjective experiences of validation and invalidation. The current study investigated both validating and invalidating experiences in seeking, accessing, and maintaining professional services among 31 Canadian youth (n = 20 girls, n = 11 boys; 12 to 21 years old [M = 16.97, SD = 2.01]) who were diagnosed or self-identified with at least one of five conditions: depression (n = 26), anxiety (n = 22), eating disorders (n = 9), autism spectrum disorder (n = 2), or conduct disorder or oppositional defiant disorder (n = 2). Youth were recruited using convenience (e.g., posted advertisements in mental health clinics) and snowball sampling methods. Journey mapping methodology (i.e., participants created visual representations of milestones of their mental health journeys) was employed accompanied by semi-structured interviews to prompt youth to expand on their experiences (e.g., “Could you describe what was happening in your life when you first felt you would need support for your mental health?”). Four themes emerged using inductive thematic analysis, marked by the presence (validation) or lack (invalidation) of: feeling heard, feeling seen, feeling understood, and receiving helpful actions. Participants also reported key consequences of validation and invalidation. Findings broaden a conceptualization of validation across supportive relationships and an understanding of factors that enhance or impede the formation or maintenance of therapeutic relationships with youth. Clinical implications and limitations are discussed.

Sensorimotor brain areas have been implicated in the recognition of emotion expressed on the face and through nonverbal vocalizations. However, no previous study has assessed whether sensorimotor cortices are recruited during the perception of emotion in speech—a signal that includes both audio (speech sounds) and visual (facial speech movements) components. To address this gap in the literature, we recruited 24 participants to listen to speech clips produced in a way that was either happy, sad, or neutral in expression. These stimuli also were presented in one of three modalities: audio-only (hearing the voice but not seeing the face), video-only (seeing the face but not hearing the voice), or audiovisual. Brain activity was recorded using electroencephalography, subjected to independent component analysis, and source-localized. We found that the left presupplementary motor area was more active in response to happy and sad stimuli than neutral stimuli, as indexed by greater mu event-related desynchronization. This effect did not differ by the sensory modality of the stimuli. Activity levels in other sensorimotor brain areas did not differ by emotion, although they were greatest in response to visual-only and audiovisual stimuli. One possible explanation for the pre-SMA result is that this brain area may actively support speech emotion recognition by using our extensive experience expressing emotion to generate sensory predictions that in turn guide our perception.

There are two commonly encountered problems in survival analysis: (a) recurrent event data analysis, where an individual may experience an event multiple times over follow-up; and (b) joint modeling, where the event time distribution depends on a longitudinally measured internal covariate. The proportional hazards (PH) family offers an attractive modeling paradigm for recurrent event data analysis and joint modeling. Although there are well-known techniques to test the PH assumption for standard survival data analysis, checking this assumption for joint modeling has received less attention. An alternative framework involves considering an accelerated failure time (AFT) model, which is particularly useful when the PH assumption fails. Note that there are AFT models that can describe data with wide ranging characteristics but have received far less attention in modeling recurrent event data and joint analysis of time-to-event and longitudinal data. In this paper, we develop methodology to analyze these types of data using the AFT family of distributions. Fitting these models is computationally and numerically much more demanding compared to standard survival data analysis. In particular, fitting a joint model is a computationally intensive task as it requires to approximate multiple integrals that do not have an analytic solution except in very special cases. We propose computational algorithms for statistical inference, and develop a software package to fit these models. The proposed methodology is demonstrated using both simulated and real data.

Laterality patterns of resting state networks (RSN) change in various neuropsychiatric conditions. Multiple sclerosis (MS) causes neuro-cognitive symptoms involving dysfunctional large-scale brain networks. Yet, whether healthy laterality patterns of RSNs are maintained in MS and whether altered laterality patterns explain disease symptoms has not been explicitly investigated. We analysed functional MRI and diffusion tensor imaging data from 24 relapsing–remitting MS patients and 25 healthy participants. We performed group-level independent component analysis and used dual regression to estimate individual versions of well-established RSNs. Voxelwise laterality indices were calculated for each RSN. Group differences were assessed via a general linear model-based approach. The relationship between functional laterality and white matter microstructural asymmetry was assessed using Tract-Based Spatial Statistics. Spearman’s correlation was calculated between laterality indices and Brief International Cognitive Assessment for Multiple Sclerosis scores. Functional laterality of the dorsal attention network showed a significant leftward shift in the MS group in the posterior intraparietal sulcus (p

This study examined reasons for romantic and sexual relationships with adult partners among men with pedohebephilic preferences (N = 125). We also explored whether age sexual orientation impacted reasons for engaging in sex with adult partners. Pedohebephilic men endorsed both non-sexual and sexual reasons for engaging in adult-partnered relationships. The top reasons for sexual relationships with adult partners were pleasure, love and commitment, physical desirability, experience seeking, and practicality. The top reasons for romantic relationships with adult partners were to gain companionship, love toward romantic partner, to escape loneliness, to engage in sexual activities, and it seemed natural. The exclusivity of attraction to children was found to be significantly related to some of the factors. These findings support differential reasons for pedophilic men engaging in adult-partnered relationships. Professionals should seek to understand the nature of their clients’ relationships and age sexual orientation to determine whether such factors are relevant. Professionals can then support clients in their search for meaningful relationships.

Alterations in social cognition, a broad term indicating our ability to understand others and adapt our behavior accordingly, have been the focus of growing attention in the past years. Some neurological conditions, such as those belonging to the frontotemporal lobar degeneration (FTLD) spectrum, are associated to varying degrees with social cognition deficits, encompassing problems with theory of mind (ToM), empathy, perception of social stimuli, and social behavior. In this review, we outline a clinical framework for the evaluation of social cognition and discuss its role in the assessment of patients affected by a range of FTLD conditions.

In this paper an easy to implement method of stochastically weighing short and long-memory linear processes is introduced. The method renders asymptotically exact size confidence intervals for the population mean which are significantly more accurate than their classic counterparts for each fixed sample size n. It is illustrated both theoretically and numerically that the randomization framework of this paper produces randomized (asymptotic) pivotal quantities, for the mean, which admit central limit theorems with smaller magnitudes of error as compared to those of their leading classic counterparts. An Edgeworth expansion result for randomly weighted linear processes whose innovations do not necessarily satisfy the Cramer condition, is established. Numerical illustrations and applications to real world data are also included.

An awareness of school-related antecedents of children’s physiological stress at the beginning of school helps educators to prevent and mitigate children’s stress, the one of the major obstacles to their well-being and academic progress. We aimed to study the effect of reading skills and social competence on first-grade students’ salivary cortisol levels in natural settings. Based on previous results of the effects of everyday situations on children’s stress according to gender, we expected that both academic and social skills would affect girls’ physiological stress more, compared to boys. Our sample consisted of 277 students (7–8 years old, 50.2% girls). We used the highest salivary cortisol level of three morning samples and a cortisol level from the middle of the school day as physiological stress indicators. Reading skills were assessed by group-administered tests and social competence by teacher ratings. We found that lower reading comprehension skills and lower disruptiveness were related to higher cortisol levels for girls but not for boys. Higher empathy and lower disruptiveness moderated the effect of better reading comprehension on higher psychological stress in the middle of the school day only for girls. By recognizing the antecedents of children’s stress and supporting their academic and social skills, children’s, especially girls’, physiological self-regulation and coping skills in the primary grades will benefit.

The Donaldson-Fujiki K\"ahler reduction of the space of compatible almost complex structures, leading to the interpretation of the scalar curvature of K\"ahler metrics as a moment map, can be lifted canonically to a hyperk\"ahler reduction. Donaldson proposed to consider the corresponding vanishing moment map conditions as (fully nonlinear) analogues of Hitchin's equations, for which the underlying bundle is replaced by a polarised manifold. However this construction is well understood only in the case of complex curves. In this paper we study Donaldson's hyperk\"ahler reduction on abelian varieties and toric manifolds. We obtain a decoupling result, a variational characterisation, a relation to $K$-stability in the toric case, and prove existence and uniqueness under suitable assumptions on the ``Higgs tensor''. We also discuss some aspects of the analogy with Higgs bundles., Comment: 43 pages. Accepted version. Upgraded the previous results to consider uniform toric K-stability

This paper proposes a method for estimating consumer preferences among discrete choices, where the consumer chooses at most one product in a category, but selects from multiple categories in parallel. The consumer's utility is additive in the different categories. Her preferences about product attributes as well as her price sensitivity vary across products and are in general correlated across products. We build on techniques from the machine learning literature on probabilistic models of matrix factorization, extending the methods to account for time-varying product attributes and products going out of stock. We evaluate the performance of the model using held-out data from weeks with price changes or out of stock products. We show that our model improves over traditional modeling approaches that consider each category in isolation. One source of the improvement is the ability of the model to accurately estimate heterogeneity in preferences (by pooling information across categories); another source of improvement is its ability to estimate the preferences of consumers who have rarely or never made a purchase in a given category in the training data. Using held-out data, we show that our model can accurately distinguish which consumers are most price sensitive to a given product. We consider counterfactuals such as personally targeted price discounts, showing that using a richer model such as the one we propose substantially increases the benefits of personalization in discounts.

The use of mindfulness interventions have increased in schools with little knowledge of how dispositional mindfulness affects cognitive processes in the developing brain. The primary objective of this research was to investigate the association between dispositional mindfulness and the neural correlates of working memory in adolescents. A secondary objective was to examine the link between adolescent dispositional mindfulness and working memory performance. Adolescents aged 11–18 (M = 13.75, SD = 1.56, n = 83) completed the Adult and Adolescent Mindfulness Scale and a functional magnetic resonance imaging N-back task. The blood oxygen level–dependent signal as well as functional connectivity of the right dorsolateral and ventrolateral prefrontal cortex was contrasted between 2-back versus 0-back conditions. Lower blood oxygen level–dependent signal in the right ventrolateral prefrontal cortex was correlated to higher Attention and Awareness scores, controlling for participants’ experience with a mindfulness practice (k = 112, FWEp = .011). Reduced functional connectivity between right ventrolateral prefrontal cortex and right dorsomedial prefrontal cortex/supplementary motor area during the 2-back compared to 0-back task was associated with higher Nonreactivity, although this did not survive correction for multiple comparisons. Dispositional mindfulness did not correlate to working memory performance. Adolescents with higher levels of Attention and Awareness and Nonreactivity may require less cognitive effort to inhibit distractors for the same level of working memory performance.

Modern virtual reality (VR) technology has garnered significant attention in the geographic visualization community for its ability to immerse users within geospatial data sets. While immersion within one-to-one models of reality offers unique and powerful perspectives from which to view spatial data, VR also allows users to transcend the physical limitations of the real world, thereby allowing them to visualize, experience, and interact with spatial data at any scale, in any virtual environment, at any time. This paper presents a collection of 3D data-driven geovisualization case studies, implemented in an immersive virtual GIScience data visualization space (IVEVA). IVEVA was purposefully designed and developed to highlight the differences in spatial data type, the challenges associated with spatial data visualization in an immersive virtual environment, and the importance of adhering to the established design heuristics of cartography, human–computer interaction, and extended reality (XR) development. Through this process, we offer our observations on how well each data type fits this medium of visualization and interpretation, and how the design heuristics play out for an immersive virtual environment that extends the practicable space in which GIScience and visual analytics are performed. Finally, we offer our perspectives, from designing and developing this prototype, on the future for immersive interface-based GIScience.

A quasiconvex function f being given, does there exist an increasing and continuous function k which makes $$k\circ f$$ convex? How to build such a k? Some words on least convex (concave) functions. The ratio of two positive numbers is neither locally convexifiable nor locally concavifiable. Finally, some considerations on the approximation of a preorder from a finite number of observations and on the revealed preference problem are discussed.

We revisit the classical Schmitter problem in ruin theory and consider it for randomly chosen initial surplus level U. We show that the computational simplification that is obtained for exponentially distributed U allows to connect the problem to m-convex ordering, from which simple and sharp analytical bounds for the ruin probability are obtained, both for the original (but randomized) problem and for extensions involving higher moments. In addition, we show that the solution to the classical problem with deterministic initial surplus level can conveniently be approximated via Erlang(k)-distributed U for sufficiently large k, utilizing the computational advantages of the advocated randomization approach.

In this study, we explore the impact of Machiavellian rhetoric on fundraising within the increasingly important context of online crowdfunding. The “all-or-nothing” funding model used by the world’s largest crowdfunding platform, Kickstarter, may be an attractive context in which entrepreneurs can utilize Machiavellian rhetoric to reach their funding goal, lest they get no funding at all. This study uses data from 76,847 crowdfunding projects posted on kickstarter.com and develops a dictionary for computer-aided text analysis (CATA) of Machiavellian rhetoric to measure the relationship between the frequency of Machiavellian rhetoric use and crowdfunding performance, operationalized as either reaching a funding goal or the number of backers who funded the project. Machiavellian rhetoric is segregated into eight facets, which are categorized into hard and soft influence tactics. Hard tactics include revenge, intimidation, betrayal, and manipulation. Soft tactics include ingratiation, supplication, self-disclosure, and persuasion. Results reveal that signals of revenge, self-disclosure, and intimidation have negative effects, whereas signals of ingratiation and persuasion have mixed positive effects on crowdfunding performance. Ingratiation is found to increase the number of backers, but not funding success. Conversely, persuasion is found to increase funding success, but not the number of backers. Surprisingly, betrayal rhetoric is positively related to both measures of crowdfunding performance. Thus, this article complements the literature on backer decision-making, entrepreneurial methods, reward-based crowdfunding, and ethics in entrepreneurship by demonstrating how the displays of potentially negative phenomena, such as Machiavellianism, have complex consequences for entrepreneurial outcomes.

Shorter telomeres mark cellular aging and are linked to chronic stress exposure as well as negative physical and psychological outcomes. However, it is unclear whether telomere length mediates associations between early stress exposure and later externalizing problems, or whether boys and girls differ in pathways to these concerns. We therefore examined associations between telomere length, early stress via negative caregiving, and children's externalizing symptom development over time in 409 three-year-old children and their parents. Telomere length mediated the association between early parental intrusiveness and later rule-breaking behavior; however, this association was moderated by children's biological sex such that parent intrusiveness was related only to boys' rule-breaking. Findings support the notion that children's telomere length may mark individual differences in responses to negative early caregiving, and highlight a potential mechanism contributing to the development of rule-breaking problems in boys.

We explain how effective automatic probability density function estimates can be constructed using contemporary Bayesian inference engines such as those based on no-U-turn sampling and expectation propagation. Extensive simulation studies demonstrate that the proposed density estimates have excellent comparative performance and scale well to very large sample sizes due a binning strategy. Moreover, the approach is fully Bayesian and all estimates are accompanied by pointwise credible intervals. An accompanying package in the R language facilitates easy use of the new density estimates.

Although people are generally motivated to perform well at work, there is often ambiguity regarding whether they are meeting their organization’s standards. As such, people often seek feedback from others. To date, feedback-seeking research has emphasized the feedback seeker, identifying traits and circumstances associated with feedback seeking, whereas far less is known about this process from the feedback source’s point of view. However, we expect that feedback sources will vary in their willingness to allocate effort toward delivering feedback. Specifically, integrating the cost-value framework of feedback with self-regulatory theories of goal prioritization, we predict that effort allocated toward a feedback episode is determined by the feedback source’s perceptions of the feedback seeker’s motives for seeking feedback. Across two complementary studies, we found perceived instrumental motives (i.e., a desire to improve one’s performance) to be positively related to the amount of effort put toward delivering feedback, and perceived image enhancement motives (i.e., a desire to impress the feedback source) to be negatively related to effort allocation. Importantly, Study 1 was a field study in which managers were asked to report on a recent episode in which a subordinate had sought their feedback, and Study 2 used an experimental design in which feedback-seeking motives were manipulated. Thus, the current research makes an important contribution to the literature by considering the often overlooked role that the feedback source plays in the feedback process. Moreover, triangulation of both field and experimental data enhances both the external and internal validity of our conclusions.

Physical reasoning appears central to understanding how the world works, suggesting adaptive function across the animal kingdom. However, conclusive evidence for inferential reasoning about physical objects is limited to primates. We systematically tested a central feature—understanding of solidity—in domestic dogs, by adapting a validated procedure (the shelf task) previously used to test children and non-human primates. Dogs watched a treat dropped into an apparatus with a shelf either present (treat landing on the shelf) or absent (treat landing on the bottom surface) and chose where to search for it (above or below the shelf). Across four studies (N=64), we manipulated visual access to the treat trajectory and apparatus interior. Dogs correctly inferred the location of treats using physical cues when the shelf was present (Study 1), and learned rapidly when visual cues of continuity were limited (Study 2), and when the shelf was absent (Study 3). Dogs were at chance when the apparatus was fully occluded, and the presence and absence of the shelf varied across trials within subjects, and showed no evidence of learning (Study 4). The findings of these four studies suggest that dogs may be able to make some inferences using solidity and continuity and do not exhibit proximity or gravity biases. However, dogs did not always search correctly from Trial 1, and failed to search correctly when the rewarded location varied within-subjects, suggesting a role for learning, and possible limits to their ability to make inferences about physical objects.

It is tempting to think that zebras, goats, lions, and similar animals matter morally, but not in quite the same way people do. This might lead us to adopt a hybrid view of animal ethics such as ‘Utilitarianism for Animals; Deontology for People’. One of the core commitments of deontology is the Doctrine of Doing and Allowing (DDA): the view that doing harm is harder to justify than allowing harm. I explore how this core tenant of deontology applies to non-person, non-human animals and whether hybrid views of animal ethics can accept it. In doing so, I aim to do three things. First, to show that my defence of the DDA can solve a problem surrounding our duties to wild animals, while making only minimal claims about animal moral status. Second, to offer an argument that for many non-person, non-human animals, we should recognise deontological constraints on their treatment, but also see those constraints as importantly different from the constraints against doing harm to persons. Third, to get clearer on how we should understand Utilitarianism for Animals and Nozickian hybrid approaches to animal ethics.

The current generation of virtual reality (VR) technologies has improved substantially from legacy systems, particularly in the resolution and latency of their visual display. The presentation of haptic cues remains challenging, however, because haptic systems do not generalise well over the range of stimuli (both tactile and proprioceptive) normally present when interacting with objects in the world. This study investigated whether veridical tactile and proprioceptive cues lead to more efficient interaction with a virtual environment. Interaction in the world results in spatial and temporal correlation of tactile, proprioceptive and visual cues. When cues in VR are similarly correlated, observers experience a sense of embodiment and agency of their avatars. We investigated whether sensorimotor performance was mediated by embodiment of the avatar hands. Participants performed a Fitts’ tapping task in different conditions (VR with no haptics, active haptics, passive haptics, and on a real touchscreen). The active-haptic condition provided abstract tactile cues and the passive haptic condition provided veridical tactile and proprioceptive cues. An additional (hybrid haptics) condition simulated an ideal passive haptic system. Movement efficiency (throughput) and embodiment were higher for the passive than for the active and no-haptics conditions. However, components of embodiment (perceived agency and ownership) did not predict unique variance in throughput. Improved sensorimotor performance and ratings of presence and realism support the use of passive haptics in VR environments where objects are in known and stable locations, regardless of whether performance was mediated by the sense of embodiment.

The aim of this study was to present a method of interpretative sociology for studying the formation and development of national public diplomacy institutions. Our goal was to apply cognitive analysis to public policy and to use a historical-discursive method to interpret the institutionalization of public diplomacy by a government. For us, cognitive analysis of public policy coordinates new perspectives and methods, especially the fruits of historical and discursive institutionalism, both to identify the cognitive and normative frames of policy formulation and to outline the dynamic relationships among institutions and political actors. By conducting an illustrative case study of China’s public diplomacy institutionalization, we demonstrated the potential of historical–discursive analysis to shed light on public diplomacy institutional change and various social and rhetorical phenomena related to Beijing’s efforts to rationalize and legitimize its foreign policy.

In this contribution, we analyze the recently adjudicated Milica van Doorn rape and murder case. In this case, committed in 1992, no suspect could be identified until investigatory actors employed familial DNA searching in 2017. Crucially, familial DNA typing raised the possibility of ethnic and racial stereotyping and profiling, particularly against the background of the first case in which familial DNA typing was used in the Netherlands: the Marianne Vaatstra case, which from the start had been marred by controversy about the ethnicity of the unknown perpetrator. In our analysis, we show how criminal justice actors managed this potential for racialization through strategically mobilizing and carefully managing multiple collectives. Drawing on the notions of multiplicity and non-coherence, we show we do not only empirically trace the situated ethics and pragmatics of familial DNA research in this specific case, but we also develop a theoretical argument on the multiple and non-coherent character of race itself and its attendant ethical, political, and methodological possibilities and obligations.

This article argues that political realists have at least two strategies to provide distinctively political normative judgements that have nothing to do with morality. The first ground is instrumental normativity, which states that if we believe that something is a necessary means to a goal we have, we have a reason to do it. In politics, certain means are required by any ends we may intend to pursue. The second ground is epistemic normativity, stating that if something is (empirically) true, this gives us a reason to believe it. In politics, there are certain empirical regularities that ought to be acknowledged for what they are. Both sources are flawed. Instrumental normativity only requires coherence between attitudes and beliefs, and one can hang on to false beliefs to preserve attitudes incompatible with reality. I may desire to eschew power relations, and accordingly I may imagine politics to be like a camping trip. Epistemic normativity, on the other hand, operates critically, striking down existing normative claims. It shows us that politics is nothing like a camping trip, but it doesn’t tell us what we should do about it (beyond abandoning some false beliefs). We conclude by showing that if the two are taken together, they remedy each other’s flaws.
