Cognitive control functions in monolingual children with developmental language disorder and in typically developing bilingual children

Alexandra Rohár Klára Marton

Publication Name: Magyar Pszichologiai Szemle

Publication Date: 2020-12-01

Volume: 75

Issue: 4

Page Range: 623-638

Description:

Purpose: The goal of this study is to present the theoretical conceptions related to cognitive control, highlighting those main components that show a close relationship with language processing. Further, our goal was to review these functions in two distinct language groups: children with developmental language disorders and typically developing bilingual children. Specifically, we were interested in the way certain factors of language competence and performance interact with the cognitive control functions. Method: We compared the cognitive control functions between monolingual children with developmental language disorders and their typically developing peers, as well as between bilingual children and their monolingual peers. The following aspects were considered for our review: the target population - school-age monolingual children with developmental language disorders or school-age typically developing bilingual children; studies that employed tasks that measure response inhibition, resistance to interference, working memory updating and cognitive flexibility. Results: Overall, there are many conflicting results in the literature due to the heterogeneity of the groups and the differences across methodological approaches. Despite these inconsistencies, children's cognitive control functions are highly associated with their language skills; while the children with developmental language disorders show deficits in resistance to interference, working memory updating, and cognitive flexibility compared to their typically developing peers, the bilingual children show superior performance in these functions compared to their monolingual peers. Response inhibition was the only function that did not differ across groups. Conclusions: Based on the above, language development shows a close relationship with a number of cognitive control functions. The interaction between cognitive control and language, however, indicates different directions in the two target groups. Whereas poor cognitive control in children with developmental language disorders may contribute to their lower level of language skills, the cognitive advantage of bilingual children is the result of their bilingual language use and practice across different social contexts.

In defense of moral liberalism

John Ryder

Publication Name: Pragmatism Today

Publication Date: 2020-12-01

Volume: 11

Issue: 2

Page Range: 13-24

Description:

Though it is much maligned, liberalism remains a vital component of any viable political and social condition. This claim can be defended, though, only once the confusions concerning the meanings of liberalism are resolved. This can be done by considering the primary contemporary challenges to liberalism, of which there are five: populist nationalism, authoritarianism, elitism, traditionalism, and moral absolutism. Each of these, though in differing ways and some more than others, are sources of illiberalism. To appreciate the meaning and import of what is here called moral liberalism, it is valuable to clarify the nature of the challenges to it and the reasons we have to prefer moral liberalism over any of its illiberal alternatives. In the end, moral liberalism may serve as a viable grounding for contemporary societies and states only in so far as it rests, not on commonly held ideas or consensus, but on the recognition of the many interests that members of groups and societies hold in common.

The European Union Strategy on Central Asia: out of game?

Laszlo Vasa

Publication Name: Romanian Journal of European Affairs

Publication Date: 2020-12-01

Volume: 20

Issue: 2

Page Range: 121-130

Description:

The Council of the European Union adopted in June 2019 its new EU Strategy on Central Asia. Besides the Eastern Partnership, the Central-Asian region is one of the most relevant areas for the EU, so determining and shaping its development priorities were of paramount importance. In this study, based on the developments and feedbacks in recent months, I would like to demonstrate how the weak EU image due to this document will be strengthened and why it is not suitable for reaching the goals which are probably even not existing. My hypotheses are: 1) in fact, the EU does not have any clear and real strategy focusing on Central Asia, 2) the EU is losing out on the game of big and middle powers interested in the region, 3) the EU cannot exploit the economic potentials of the region.

Influence of Twitter activity on the stock price of soccer clubs

József Stéger Attila Sóti Alessandro Ancarani Gábor Vattay

Publication Name: Social Network Analysis and Mining

Publication Date: 2020-12-01

Volume: 10

Issue: 1

Page Range: Unknown

Description:

The interrelation between the fluctuations of stock prices of football clubs and the social media activity of their fans is of major economic interest. The results in this research provide measurable support for the suggestion that financial market activities and the number of tweets are linked in the case of big football clubs. The novelty of the research is to show which daily ratio of tweet counts and their mood can predict the stock market. Based on these findings, sport managers could use social media strategically to build better relationships with consumers and stakeholders.

Application of the spme technique for determinate the quality indicators of dairy products

E. Lakatos Székelyhidi Rita Zsolt Ajtony

Publication Name: Elelmiszervizsgalati Kozlemenyek

Publication Date: 2020-12-01

Volume: 66

Issue: 4

Page Range: 3188-3201

Description:

Solid Phase Microextraction (SPME) is a relatively new extraction technique that combines taking samples from a mixture with a simpler desorption of the components to be analyzed of the unenriched sample in its original state in the analytical instrument. Based on a large number of publications in the literature, the authors describe the possibilities of using the SPME technique in the case of dairy products. The main groups of components that can be detected by the SPME sampling procedure, such as fatty acids, aldehydes and ketones, esters, alcohols, sulfur-containing organic compounds, furans, phenols and terpenoids are presented, through examples in the literature. Due to the limited scope of the manuscript, the authors report only on the possibilities of sample preparation using the SPME technique. Instrumental analytical methods following solid state microextraction, mainly using gas or liquid chromatography, are not described. Details of instrumental analyses are available in the cited literature sources.

Model Identification Based on Sparse or Non-Uniform Datasets using Tensor Product Function Manipulations

Adam B. Csapo

Publication Name: Gpmc 2020 2nd IEEE International Conference on Gridding and Polytope Based Modeling and Control Proceedings

Publication Date: 2020-11-19

Volume: Unknown

Issue: Unknown

Page Range: 49-52

Description:

This paper presents an approach for creating tensor product (TP) models based on sparse or non-uniform samples representing arbitrary datasets, and for manipulating the resulting TP structure to further identify the models behind the datasets. Given the usefulness of TP models in merging together closed algebraic formulae and tensor representations, it is argued that the proposed approach can be applied towards understanding the underlying complexity of a given dataset, while iteratively arriving at a model for the process that generated it. The key idea behind the approach is demonstrated using a dataset on sound pressure levels generated by different-sized airfoils in a wind tunnel.
