Objective: The purpose of this study was to reexamine the latent structure of ADHD and sluggish cognitive tempo (SCT) due to issues with construct validity. Two proposed changes to the construct include viewing hyperactivity and sluggishness (hypoactivity) as a single continuum of activity level, and viewing inattention as a separate dimension from activity level. Method: Data were collected from 1,398 adults using Amazon’s MTurk. A new scale measuring activity level was developed, and scores of Inattention were regressed onto scores of Activity Level using curvilinear regression. Results: The Activity Level scale showed acceptable levels of internal consistency, normality, and unimodality. Curvilinear regression indicates that a quadratic (curvilinear) model accurately explains a small but significant portion of the variance in levels of inattention. Conclusion: Hyperactivity and hypoactivity may be viewed as a continuum, rather than separate disorders. Inattention may have a U-shaped relationship with activity level. Linear analyses may be insufficient and inaccurate for studying ADHD.

Purpose As a part of adaptive and complex system thinking, geographic information systems (GIS) are beneficial particularly for transportation projects, where uncertainty is frequent. Accordingly, this paper aims to examine the utilization of GIS in line with adaptive and complex system thinking, as the basis of the methodical formulation of perceived gaps within the integrated transportation planning (ITP) specifically for the mega transportation projects. Such a framework is undertaken, as the mega transportation projects although may seem straightforward, however, are problematic and require more consideration than the traditional triple bottom line factors. Using the Sydney Metro as the case study, the outcome demonstrates the significance of the fourth separate dimension of engineering into the aforementioned bottom-line factors. Design/methodology/approach The research examines the utilization of adaptive and complex system thinking, as the basis of the methodical formulation of perceived gaps within the ITP. The use of Sydney’s Metro project is a novel example of the proposed methodical formulation and its empirical assessment and provides a better understanding of the use of mapping and planning tools for mega transportation projects. Findings Aptly, using the developed conceptual framework, this research further validates the inclusion of a separate engineering dimension with the usual triple bottom line factors. Such inclusion is paramount in responding to the existing ITP gaps found within the current literature. Originality/value This research uses GIS and ITP process to support the aforementioned adaptive and complex system thinking. This, in turn, is used as the basis of a methodical formulation framework in dealing with mega rail transportation infrastructure. To support such a proposition, Sydney Metro is examined as the basis of a case study.

Factor analysis of five self-statement categories in a study of speech anxiety produced two factors, performance-based thinking and off-task thinking. The highly specific thought categories utilized in the present study, and most others, are not independent. Effective on-task, noneffective on-task, positive self-evaluation, and negative self-evaluation are all significantly inter-correlated and load together on Factor I, while off-task thinking loaded by itself on Factor II. Of the categories commonly treated as independent, only off-task thinking actually formed a separate dimension. Researchers need to reconsider the utility of separately categorizing effective on-task thoughts, noneffective on-task thoughts, positive self-evaluation, and negative self-evaluation. They do not represent independent categories.

The socio-political characteristics of the host environment influence investment decisions. The complexity of the political setup strengthens the need for advanced research in the field. The main contribution of this article is to identify the party polarization as a separate dimension of the political system. This paper examines the relationship between the foreign direct investment (FDI) inflows and the host country political factors: the party polarization and the political stability. Besides constructing the political polarization index in a traditional way, authors also formulate a novel measure, which explicitly shows the divergence of political parties on economic actions. By using the manifesto data of 50 parliamentary democracies based on fixed effects model, authors conclude that political polarization is an important socio-political factor which has been previously neglected in literature while addressing the determinants of foreign investments. The paper shows that the effect of political polarization on FDI inflows changes for country groups of different institutional and development indicators. Authors underline the importance of political instability in tackling the polarization impact on capital flows. Accounting together the two variables, the authors find a negative significant effect on FDI.

This is the first large-scale, quantitative study of the evaluative dimensions and potential predictors of Quebec-based parents’ attitudes towards childhood multilingualism. Such attitudes are assumed to constitute a determinant of parental language choices, and thereby influence children’s multilingual development. The newly-developed Attitudes towards Childhood Multilingualism Questionnaire was used to gather data from 826 participants raising an infant/toddler aged 0-4 years with multiple languages. The results reveal three separate dimensions: status and solidarity (the same dimensions found in attitudes towards individual languages) as well as cognitive development (not previously attested as a separate dimension). The study thus advances knowledge regarding the dimensionality of attitudes. Participants’ approach to promoting multilingualism and the combination of languages transmitted – and specifically, whether this included a heritage language – correlated significantly with parental attitudes towards childhood multilingualism. Parents’ linguistic background and location within Quebec were not significant predictors of attitudes. The paper discusses directions for further research.

Since the discovery, research on iron-based superconductivity (SC) has become one of the main streams in condensed matter physics [1]. The interplay between structure, magnetism and SC is one of most intriguing subjects of this field. The common structural feature is the presence of square planar sheets of Fe atoms coordinated tetrahedrally by pnictogens or chalcogens. They have been, at the early stage, realized in the ZrCuSiAs (1111), ThCr2Si2 (122), anti-PbO (11) and Cu2Sb (111) structures. To gain further insight into the mechanism of the SC and variation of magnetic orders, investigation of Fe-based compounds with a separate spatial dimension is important. This is because the dimensionality should influence magnetism and can control itinerancy of electrons by changing Fermi surface topology. As spin ladders in copper oxides shed a new light on the mechanism of SC, a study on an analogue with ladder geometry among Fe-based compounds is highly desired. Here we report our recent studies of iron-based ladder compounds AFe2X3 (A = K, Rb, Cs, Ba; X = S, Se, Te) [2,3]. Crystal structure is novel, comprising of FeX4 tetrahedra with channels which host A atoms, and four-fold coordinated Fe2+ ions form two-leg ladder geometry. Unlike most of parent compounds of the Fe-based SCs, the ladder compounds are insulating down to the lowest measured temperature. Through bulk properties and neutron diffraction measurements, a variety of magnetic structures and low dimensional characteristics were elucidated. These would provide a clue of the SC realized in a separate dimension systems. The description of theory that accounts for the observed magnetic structures will be also presented.

AbstractSeveral studies have attempted to understand the dimensions of psychiatric symptoms in manic episodes, but only a few have been able to model the latent structure of mania in bipolar disorder patients using confirmatory factor analysis. The objective of the present study was to search for the best model of the symptomatology of hospitalized manic patients. To achieve this goal, 117 manic inpatients during a manic crisis participated in this research. Exploratory factor analysis was conducted followed by confirmatory factor analysis using an exploratory factor analysis solution and three other theory-based models. The exploratory factor analysis results revealed a six-factor structure: depression, suicide, insomnia, mania, psychosis, and anxiety. This solution also presented the best fit to the data when tested with confirmatory factor analysis. A five-factor solution, without suicide as a separate dimension, appeared to be more theoretically suitable. Another important finding was that anxiety was an independent dimension in mania. Some hypotheses are discussed in light of contemporary theories, and future studies should investigate this aspect further.

Approximately 1 billion slum dwellers worldwide are exposed to increased health risks due to their spatial environment. Recent studies have therefore called for the spatial environment to be introduced as a separate dimension in medical studies. Hence, this study investigates how and on which spatial scale relationships between the settlement morphology and the health status of the inhabitants can be identified. To this end, we summarize the current literature on the identification of slums from a geographical perspective and review the current literature on slums and health of the last five years (376 studies) focusing on the considered scales in the studies. We show that the majority of medical studies are restricted to certain geographical regions. It is desirable that the number of studies be adapted to the number of the respective population. On the basis of these studies, we develop a framework to investigate the relationship between space and health. Finally, we apply our methodology to investigate the relationship between the prevalence of slums and different health metrics using data of the global burden of diseases for different prefectures in Brazil on a subnational level.
