Factor structure of the construct of adaptive behavior in children with and without intellectual disability

Although the presence of significant limitations in adaptive behavior constitutes one of the three necessary criteria for diagnosing intellectual disability, adaptive behavior structure has always been the subject of considerable controversy among researchers. The main goal of this study is to extend previous research results that provide further support to a multidimensional structure of conceptual, social, and practical skills compared to the unidimensional structure. One-factor and 3-correlated factors models as measured by 15 observable indicators were analyzed by means of confirmatory factor analysis (CFA), as well as their relationships with one second-order factor (i.e., adaptive behavior). To that end, 388 children with and without intellectual disabilities were assessed with the Diagnostic Adaptive Behavior Scale (DABS). Results of CFA indicated that the 3 first-order factors solution provides the best fit to the data. Reliability and validity of the multidimensional model were also analyzed through different methods such as the composite reliability and the average variance extracted. Finally, implications of these findings and possible directions for future research are discussed.

Differences in First Graders' School Adjustment: the Role of Classroom Characteristics and Social Structure of the Group

We examined differences among classes in academic and psychosocial aspects of school adjustment. The sample consisted of 1241 6-7-year-olds in 71 classes from 49 schools. Multilevel analyses showed that 83.5% of the variance was at the child level, 10.3% at the class level, and 6.2% at the school level. Thus, for the part of the variance that was not at the child level, differences among classes were more important than differences among schools. To identify relevant class factors, we focused on classroom characteristics and aspects of the social structure in the class such as integration and openness. Classroom and teacher variables were relatively unimportant compared to social structure indices that yielded significant correlation indicators of social interaction and intellectual competence and explained part of their variance at the class level. This suggested that the structure of the social relations contributed to differences among classes in several aspects of school adjustment.     

On the Standard and Rational Completeness of some Axiomatic Extensions of the Monoidal T-norm Logic

The monoidal t-norm based logic MTL is obtained from Hájek's Basic Fuzzy logic BL by dropping the divisibility condition for the strong (or monoidal) conjunction. Recently, Jenei and Montgana have shown MTL to be standard complete, i.e. complete with respect to the class of residuated lattices in the real unit interval [0,1] defined by left-continuous t-norms and their residua. Its corresponding algebraic semantics is given by pre-linear residuated lattices. In this paper we address the issue of standard and rational completeness (rational completeness meaning completeness with respect to a class of algebras in the rational unit interval [0,1]) of some important axiomatic extensions of MTL corresponding to well-known parallel extensions of BL. Moreover, we investigate varieties of MTL algebras whose linearly ordered countable algebras embed into algebras whose lattice reduct is the real and/or the rational interval [0,1]. These embedding properties are used to investigate finite strong standard and/or rational completeness of the corresponding logics.     

Artificial intelligence for the measurement of vocal stereotypy

Both researchers and practitioners often rely on direct observation to measure and monitor behavior. When these behaviors are too complex or numerous to be measured in vivo, relying on direct observation using human observers increases the amount of resources required to conduct research and to monitor the effects of interventions in practice. To address this issue, we conducted a proof of concept examining whether artificial intelligence could measure vocal stereotypy in individuals with autism. More specifically, we used an artificial neural network with over 1,500 minutes of audio data from 8 different individuals to train and test models to measure vocal stereotypy. Our results showed that the artificial neural network performed adequately (i.e., session-by-session correlation near or above .80 with a human observer) in measuring engagement in vocal stereotypy for 6 of 8 participants. Additional research is needed to further improve the generalizability of the approach.     

On the Meaning of Words and Dinosaur Bones: Lexical Knowledge Without a Lexicon

Although for many years a sharp distinction has been made in language research between rules and words—with primary interest on rules—this distinction is now blurred in many theories. If anything, the focus of attention has shifted in recent years in favor of words. Results from many different areas of language research suggest that the lexicon is representationally rich, that it is the source of much productive behavior, and that lexically specific information plays a critical and early role in the interpretation of grammatical structure. But how much information can or should be placed in the lexicon? This is the question I address here. I review a set of studies whose results indicate that event knowledge plays a significant role in early stages of sentence processing and structural analysis. This poses a conundrum for traditional views of the lexicon. Either the lexicon must be expanded to include factors that do not plausibly seem to belong there; or else virtually all information about word meaning is removed, leaving the lexicon impoverished. I suggest a third alternative, which provides a way to account for lexical knowledge without a mental lexicon.     

With a little help from my friends: A computational model for the role of social support in mood regulation

The growing interest in the role of social support in mental and physical health has led to the development of several intelligent systems that aim to use social mechanisms to simulate healthy behaviour. In this paper a computational model of a human agent is presented which describes the effect of social support on mood. According to the literature, social support can either refer to the social resources that individuals perceive to be available or to the support that is actually provided in problematic situations. The proposed model distinguishes between both roles of social support. The role of social network characteristics has been taken into account, as an individual can perceive or receive social support through his/her social network. In addition, the number of connections (friends), strength of ties (relationships), social isolation and social integration have been studied. Simulation experiments have been done to analyze the effect of the different types of support in different scenarios and also to analyze the role of various social network characteristics on the mood level. It is shown that support can help to reduce the induced stress and thus can contribute to healthy mood regulation and prevention of depression. The presented model provides a basis for an intelligent support system for people with mood regulation problems that take the social network of people into account.     

Embedding Logics into Product Logic

We construct a faithful interpretation of ukasiewicz's logic in product logic (both propositional and predicate). Using known facts it follows that the product predicate logic is not recursively axiomatizable.We prove a completeness theorem for product logic extended by a unary connective of Baaz [1]. We show that Gödel's logic is a sublogic of this extended product logic.We also prove NP-completeness of the set of propositional formulas satisfiable in product logic (resp. in Gödel's logic).     

Ingratiation as an adapting strategy: Its relationship with career adaptability,career sponsorship,and promotability

Guided by the Career Construction Theory (Savickas, 2013), our research model posits that individuals rely on their adaptability resources and implement adapting responses, in the form of ingratiation, to increase their promotability at work. In addition, the indirect relationship between career adaptability and promotability via ingratiation is further strengthened by high career sponsorship. The research model was tested and the translated Career Adapt-Abilities Scale (CAAS) Thailand form was validated using a cross-sectional survey of 265 subordinate–supervisor dyads. Results demonstrate adequate levels of internal consistency (ɑ = .96) and the factor structure corresponded with prior CAAS international validation. The moderated mediation model was supported and as expected: (a) ingratiation, as an adapting response, mediated the positive relationship between career adaptability and promotability, and (b) the mediated relationship between career adaptability and promotability via ingratiation was stronger for individuals with higher career sponsorship. Taken together, the findings support the cross-national measurement equivalence and utility of CAAS in non-Western and developing countries. More importantly, our study offers the groundwork for understanding adapting responses and the augmenting role of career-specific contextual support.
