The negative interpretation of body sensations (e.g., as sign of a severe illness) is a crucial cognitive process in pathological health anxiety (HA). However, little is known about the nature and the degree of automaticity of this interpretation bias. We applied an implicit association test (IAT) in 20 subjects during functional magnetic resonance imaging (fMRI) to investigate behavioral and neural correlates of implicit attitudes towards symptom words. On the behavioral level, body symptom words elicited strong negative implicit association effects, as indexed by slowed reaction times when symptom words were paired with the attribute “harmless” (incongruent condition) relative to a contro…

Obsessional and Eating Disorder-related Intrusive Thoughts: Differences and Similarities Within and Between Individuals Vulnerable to OCD or to EDs

2016

Unwanted intrusive cognitions constitute the normal variant of clinically significant intrusive cognitions found in disorders such as obsessive-compulsive disorder (OCD) and eating disorders (EDs). This study investigates whether individuals who are vulnerable to OCD or EDs experience more intrusions than people with no vulnerability to these disorders, and it examines the consequences of obsessional (OITs) and eating disorder (EDITs) intrusions in the same individuals, taking into account their susceptibility to OCD, EDs or neither of the two. From a sample of 922 participants, three groups were formed: risk of OCD (n = 92), risk of EDs (n = 41) and a no-risk group (n = 100). EDITs were mo…

Validation of the Weight Bias Internalization Scale for Mainland Chinese Children and Adolescents

2021

Weight stigma internalization among adolescents across weight categories leads to adverse psychological consequences. This study aims to adapt and validate a Chinese version of the Weight Bias Internalization Scale for Mainland Chinese children and adolescents(C-WBIS). A total of 464 individuals aged 9 to 15 years participated in the present study. Based on item response theory (IRT) and classical test theory (CTT), we selected the items for the C-WBIS and evaluated its reliability and validity. The item response theory yields support for the one-dimensional factor mode. All item parameters fit the IRT model (albeit within an adequate range), eight items were adopted. No evidence of signifi…

Layering of IFRS and Dual Institutionality of Accounting Standards in Belarus

2017

Submitted version of an article published in the journal Accounting in Europe. There is an ongoing debate about the applicability and efficacy of International Financial Reporting Standards (IFRS) adoption in countries with diverse institutional infrastructures. We examine financial reporting in Belarus and factors that are shaping its development. In Belarus, IFRS has been adopted through layering where it is an additional requirement to the existing reporting specified by the national accounting regulations. We explore how global standards were transposed and function in a highly specific institutional context. Based on an examination of reporting in the banking sector, we conclude that d…

Novel Distance Estimation Methods Using 'Stochastic Learning on the Line' Strategies

2018

In this paper, we consider the problem of Distance Estimation (DE) when the inputs are the $x$ and $y$ coordinates (or equivalently, the latitudinal and longitudinal positions) of the points under consideration. The aim of the problem is to yield an accurate value for the real (road) distance between the points specified by the latter coordinates. 1 This problem has, typically, been tackled by utilizing parametric functions called the “Distance Estimation Functions” (DEFs). The parameters are learned from the training data (i.e., the true road distances) between a subset of the points under consideration. We propose to use Learning Automata (LA)-based strategies to solve the problem. In par…

Asymmetry matters: Dynamic half-way points in bidirectional labeling for solving shortest path problems with resource constraints faster

2017

Abstract With their paper “Symmetry helps: Bounded bi-directional dynamic programming for the elementary shortest path problem with resource constraints” [Discrete Optimization 3, 2006, pp. 255–273] Righini and Salani introduced bounded bidirectional dynamic programming (DP) as an acceleration technique for solving variants of the shortest path problem with resource constraints (SPPRC). SPPRCs must be solved iteratively when vehicle routing and scheduling problems are tackled via Lagrangian relaxation or column-generation techniques. Righini and Salani and several subsequent works have shown that bounded bidirectional DP algorithms are often superior to their monodirectional counterparts, s…

Using Genetic Algorithms for Optimizing the PPC in the Highway Horizontal Alignment Design.

2016

Various studies have emphasized the interesting advantages related to the use of new transition curves for improving the geometric design of highway horizontal alignments. In a previous paper, one of the writers proposed a polynomial curve, called a polynomial parametric curve (PPC), proving its efficiency in solving several design problems characterized by a very complex geometry (egg-shaped transition, transition between reversing circular curves, semidirect and inner-loop connections, and so on). The PPC also showed considerable advantages from a dynamic perspective, as evidenced by the analysis of the main dynamic variables related to motion (as well as rate of change of radial accelera…

Amplitude and peculiar aspects of social inequalities in the French school

2005

05021http://www.scielo.br/pdf/ep/v31n1/a02v31n1.pdf; International audience; French sociology denounces vehemently since the end of the 1960s the important and standing social inequalities both in the access to the different levels of education and in school success stricto sensu. Such criticism has taken the form of a general theory put forward by Bourdieu and Passeron, in which such social inequalities are shown to be the necessary result of the functioning of the school institution. And this thesis, hugely influential not just among sociologists, but also more widely, has contributed to foster certain fatalism, since it establishes that the very function of school is to reproduce and leg…

Packing colorings of subcubic outerplanar graphs

2018

Given a graph $G$ and a nondecreasing sequence $S=(s_1,\ldots,s_k)$ of positive integers, the mapping $c:V(G)\longrightarrow \{1,\ldots,k\}$ is called an $S$-packing coloring of $G$ if for any two distinct vertices $x$ and $y$ in $c^{-1}(i)$, the distance between $x$ and $y$ is greater than $s_i$. The smallest integer $k$ such that there exists a $(1,2,\ldots,k)$-packing coloring of a graph $G$ is called the packing chromatic number of $G$, denoted $\chi_{\rho}(G)$. The question of boundedness of the packing chromatic number in the class of subcubic (planar) graphs was investigated in several earlier papers; recently it was established that the invariant is unbounded in the class of all sub…

An experimental study on the effect of systemic functional linguistics applied through a genre-pedagogy approach to teaching writing

2016

Abstract In the tradition of teaching English as a second language, there has been an increased interest in how functional language descriptions and understandings of genres may be used as resources for making meaning. The present study investigates what impact writing instruction that draws upon systemic functional linguistics (SFL) applied through a genre-pedagogy approach has on students’ ability to write argumentative essays. This includes explicit grammar instruction inspired by SFL, as well as instruction on text structure. The study uses a mixed-methods approach, with a quasi-experiment followed up by quantitative and qualitative analyses of the collected material. Statistical analys…
