Responsiveness and Minimal Clinically Important Difference of the Five Times Sit-to-Stand Test in Patients with Stroke
2021
This study aimed to analyze the responsiveness of the 5STS test among stroke patients and to estimate the MCIDs (minimal clinically important differences) for different severity levels of community ambulation and stages of recovery. The 5STS and comparator instruments (gait speed and Functional Ambulatory Category (FAC)) were evaluated at baseline. These measures were repeated at 4 (Stage 1) and 8 weeks (Stage 2), together with the Global Rating of Change (GROC). The MCIDs were calculated with two anchor-based methods using the GROC as the external criterion. Responsiveness to change for the 5STS was estimated analyzing the correlation with changes in the two comparator instruments and thei…
Evaluation of geomorphometric characteristics and soil properties after a wildfire using Sentinel-2 MSI imagery for future fire-safe forest
2021
Abstract Understanding spatiotemporal geomorphological and pedological changes as a consequence of wildfires can allow stakeholders, land planners, and policymakers to design efficient fire safety-based afforestation and restoration programs of forest lands. The use of remote sensing techniques is a key tool to achieve this goal. The suitable combination of Sentinel-2 MSI data for mapping of different spectral indices related to burn severity and their relationship with other morphometric and soil properties can contribute to a better understanding of the impact of fire, and this is relevant in regions where is still scarce fire-related research such as Turkey. In this investigation, the us…
Dynamic Functional Connectivity Captures Individuals’ Unique Brain Signatures
2020
Recent neuroimaging evidence suggest that there exists a unique individual-specific functional connectivity (FC) pattern consistent across tasks. The objective of our study is to utilize FC patterns to identify an individual using a supervised machine learning approach. To this end, we use two previously published data sets that comprises resting-state and task-based fMRI responses. We use static FC measures as input to a linear classifier to evaluate its performance. We additionally extend this analysis to capture dynamic FC using two approaches: the common sliding window approach and the more recent phase synchrony-based measure. We found that the classification models using dynamic FC pa…
Foreign Language learning and teaching Enjoyment: Teachers’ Perspectives
2019
Aim. The primary objective of the present study was to investigate the level of Foreign Language learning Enjoyment and Foreign Language teaching Enjoyment experienced by foreign language teachers in Poland. The secondary aim of the study was to investigate the sources of FLE from the perspective of FL teachers.
 Methods. The informants of the study were Polish educators teaching foreign languages at different educational levels (from primary to tertiary education). To compute the obtained quantitative data, the statistical program STATISTICA was used. Standard descriptive and inferential statistics were used to report means, median and standard deviation for sociodemographic and base…
Validity and fairness of a new entry diagnostics test in higher education economics
2020
Abstract Research has been focusing increasingly on measuring students’ prior economic knowledge in higher education. However, in German-speaking countries, valid instruments are rare. A diagnostic study investigated the validity and fairness of an internationally established economic knowledge test (adapted German version of TUCE IV and TEL IV) with a representative sample of 7664 students from 46 universities across Germany. Previous findings with the dataset ( Zlatkin-Troitschanskaia et al., 2019a ) suggest that native language significantly predicts missing answers in the knowledge test. Similar effects can be found for gender. After coding missing answers as incorrect, students with a …
The hierarchical factor model of ADHD: invariant across age and national groupings?
2011
Attention-Deficit/Hyperactivity Disorder (ADHD) is characterized by problems with attention, impulsivity, and hyperactivity. The diagnosis derives from 18 symptoms indexing these behavioural domains [American Psychiatric Association (APA), DSM-IV-TR, 2000]. There is substantial continuity in maintaining a diagnosis of ADHD from childhood to adolescence (Faraone, Biederman, & Mick, 2006); however the phenotypic expression is highly variable within the diagnosed group and across time (Barkley, 2006; Nigg, 2006). Current diagnostic formulations distinguish between symptoms of inattention and those of hyperactivity-impulsivity. Three ADHD subtypes are recognized in the DSM-IV: the predominantly…
Gender-Dependent Associations of Anxiety and Depression Symptoms With Eating Disorder Psychopathology in a Representative Population Sample
2021
Background:Evidence shows that anxiety and depressive disorders play an important role in eating disorder behavior. However, given the epidemiology of eating disorders, there is a need to investigate potentially gender-specific connections.Method:This study tested the associations of anxiety and depression symptoms with eating disorder symptoms and behaviors and explored whether they differed between men and women. Within a population-representative survey (N= 2,510; ages 14–94), participants completed measures of depression symptoms (PHQ-2), anxiety symptoms (GAD-2), and eating disorder symptoms (EDE-Q8). We conducted linear regression analyses of the EDE-Q8 sum score and General Linear Mo…
Self-image and psychological distress in treatment-seeking adolescents
2017
Background: Adolescence has been recognized as a critical period for mental health during which it is fundamental to the well-being of adolescents to provide early and appropriate mental health interventions. Self-image perceptions play a particularly relevant role during adolescence since individuals are extensively involved in reorganizing their identity and relationships. Although the self-image development implies adaptive outcomes for most adolescents, some age-related tasks can be difficult to deal with and lead to psychological suffering for a minority of them. Method: This study examined how domain-specific self-image was associated with psychological distress in 128 treatment-seeki…
THE RELATIONSHIP BETWEEN FOREIGN LANGUAGE ENJOYMENT AND GENDER AMONG SECONDARY GRAMMAR SCHOOL STUDENTS
2018
In the context of second language acquisition, foreign language enjoyment (FLE) is a relatively new concept. For that reason, none of the few research carried out in the field thus far has been focused on whether gender might be an important determinant of either a high or a low level of FLE. Thus, the purpose of the present paper was to examine the influence of FLE on learning English as a foreign language, as well as to investigate this relationship from the perspective of gender. The results of this study revealed that there are no statistically significant differences between males and females in FLE, while such differences are found in terms of the sources of FLE each gender perceives …
Orientation-invariance of individual differences in three face processing tasks
2019
Numerous studies have reported impairments in perception and recognition, and, particularly, in part-integration of faces following picture-plane inversion. Whether these findings support the notion that inversion changes face processing qualitatively remains a topic of debate. To examine whether associations and dissociations of the human face processing ability depend on stimulus orientation, we measured face recognition with the Cambridge Face Memory Test (CFMT), along with experimental tests of face perception and selective attention to faces and non-face objects in a sample of 314 participants. Results showed strong inversion effects for all face-related tasks, and modest ones for non-…
