Control cognitions and causal attributions as predictors of fatigue severity in a community sample

Control cognitions and causal attributions of fatigue were examined in relation to Weiner's Causal Attribution theory in a community sample. Participants were 97 females and 43 males, aged 18-83 years. Weiner's dimensions of stability and uncontrollability and physical and psychosocial attributions of fatigue were related to fatigue severity. Escape-avoidance coping mediated between psychosocial causal attributions of fatigue to fatigue; whereas planful problem-solving and exercise moderated between stability cognitions to fatigue and psychosocial attributions of fatigue to fatigue, respectively. This, the cause(s) of fatigue were perceived as stable, uncontrollable, and involving physical and psychosocial factors, participants reported worse fatigue. Taken together, the results suggest that fatigue treatments may be most effective when they are tailored or matched to the belief systems of the individuals with fatigue.     

Cyclists' perception of cycling infrastructure – A Repertory Grid approach

Previous research indicate that cyclists prefer safe and comfortable infrastructure. However, concepts like safety or comfort may be understood and defined in different ways by different individuals. Moreover, these concepts are so broad that it is unclear to which specific characteristics of the traffic infrastructure they are linked. Therefore, the aim of this study is to inductively examine individual evaluation criteria that cyclists use to perceive and evaluate certain route attributes. Using the Repertory Grid technique, we elicited the personal constructs of 23 participants about given route attributes and asked them to rate every attribute on every construct. The constructs were categorized and clustered resulting in five evaluation criteria, namely Mental Comfort, Physical Comfort, Interaction, Environment, and Ease of Use. Both comfort clusters were rated the most relevant for route choice, but they strengthen the suggestion of two distinct aspects of comfort, one referring to mental stress, the other referring to physical effort. Furthermore, the analyses revealed Interaction as a relatively new route criterion which also raises a new view on the negative evaluation of motor traffic and expands the concept of stress. Regarding the evaluation of route attributes, a high traffic volume and cobbled stone were rated the most negative, whereas separated cycling facilities were evaluated as most positive. Findings of this study expand existing research by qualitative insights and provide a more detailed understanding of route criteria like comfort or safety. This can be used to enhance cycling facilities and to offer preferable infrastructure for cyclists.     

Ibn al-Ṭayyib’s Trinitarian Formulation in the Islamic Milieu

This article examines a theological treatise of Abū al-Faraj ?Abd Allāh Ibn al-?ayyib, a savant of the Assyrian Church of the East. The treatise discusses the Attributes of Deity demonstrating a thematic correspondence with the dominant polemical arguments occasioned by the Christian view of the Trinity and Christology. These include the relation of the hypostases to the attributes of essence, specifically the unity of the divine essence in contrast to the plurality of the hypostases. Ibn al-?ayyib also borrows concepts from the Muslim milieu to commend his Christian formulation. Most notable among these is the Ash?arī concept of the divine attributes (?ifāt) and their categorization. The Ash?arīs had limited the attributes of essence to seven. Ibn al-?ayyib limits them to three: paternity, filiation and procession. The article considers Ibn al-?ayyib’s Christian intellectual forebears, demonstrating that he used and amended their formulations. Finally, two Muslim polemicists are considered to establish that Ibn al-?ayyib was engaging with specific objections concerning the Christian Trinity. This thematic correspondence warrants a reconsideration of Ibn al-?ayyib’s contribution to the Muslim–Christian interface. Although never an explicitly polemic theologian, the savant-priest developed an implicit apologetic through his theological treatises that provided intellectual fortification for his Christian community.     

The Third Treatise of Shaykh Abū al-Faraj ʿAbd Allāh Ibn al-Ṭayyib on Unity and Trinity

The article consists of a critical Arabic edition and English translation of the Third Treatise of Shaykh Abū al-Faraj ?Abd Allāh Ibn al-?ayyib. The introduction provides a brief, general orientation to the treatise, discussing its relation to two other treatises by the same author and suggesting a chronology. The translation accompanies an article analysing the treatise titled: ‘Ibn al-?ayyib’'s Trinitarian Formulation in the Islamic Milieu’ (Kuhn, M. 2018. “Ibn al-?ayyib’s Trinitarian Formulation in the Islamic Milieu.” Islam and Christian–Muslim Relations 29 (2): 123–143).     

The Flynn effect,group differences,and g loadings

Flynn effect gains are predominantly driven by environmental factors. Might these factors also be responsible for group differences in intelligence? Group differences in intelligence have been clearly shown to strongly correlate with g loadings. The empirical studies on whether the pattern of Flynn effect gains is the same as the pattern of group differences yield conflicting findings. We present new evidence on the topic using a number of datasets from the US and the Netherlands. Score gains and g loadings showed a small negative average correlation. The general picture is now that there is a small, negative correlation between g loadings and Flynn effect gains. It appears that the Flynn effect and group differences have different causes.     

Improving psychological critical thinking in Australian university students

This study tested the psychological critical thinking attributes of students undertaking an Australian Psychology Accreditation Council (APAC) approved course. It also assessed an instructional based teaching practice designed to improve psychological critical thinking skills. The participants were 84 second year and 60 fourth year psychology students enrolled at the University of Western Sydney, Australia. Participants were tested at the beginning and end of the semester with the Psychological Critical Thinking Exam (PCTE) ( Lawson, 1999 ) and only the second year group received specific critical thinking instructions. The results revealed a significant (p < .001) increase in mean PCTE score for the second year group, but no significant increase for the fourth year group. These results confirm the value of the instructional based teaching practice and support the graduate attributes expected by the APAC.     

Preferences for multi-attributed alternatives: Traces, dominance, and numerical representations

This paper analyzes conjoint measurement models allowing for intransitive and/or incomplete preferences. This analysis is based on the study of marginal traces induced on coordinates by the preference relation and uses conditions guaranteeing that these marginal traces are complete.Within the framework of these models, we propose a simple axiomatic characterization of preference relations compatible with the notion of dominance. We show that all such relations have a nontrivial numerical representation.Our results allow us to establish useful connections between two lines of thought in the area of decision analysis with multiple attributes that have largely remained unrelated: the one based on conjoint measurement and the one emphasizing the idea of dominance.     

Differential brain responses when applying criterion attribute versus family resemblance rule learning

Subsystems of category learning have been identified on the basis of general domains of content (e.g., tools, faces). The present study examined categories from the standpoint of internal structure and determined brain topography associated with expressing two fundamentally different category rule structures (criterion attribute, CA, and family resemblance, FR). CA category learning involves processing stimuli by isolated features and classifying by properties held by all members. FR learning involves processing stimuli by integral wholes and classifying on overall similarity among members without sharing identical features. fMRI BOLD response to CA and FR categorization was measured with pseudowords as stimuli. Category knowledge for both tasks was mastered prior to brain imaging. Areas of activation emerged unique to the structure of each category and followed from the nature of the rule abstraction procedure. CA categorization was implemented by strong target monitoring and expectation (medial parietal), rule maintenance in working memory, feature selection processes (inferior frontal), and a sensitivity to high frequency components of the stimulus such as isolated features (anterior temporal). FR categorization, consistent with its multi-featural nature, involved word-level processing (left extrastriate) that evoked articulatory rehearsal (medial cerebellar). The data suggest category structure is an important determinant of brain response during categorization. For instance, anterior temporal structures may help attune visual processing systems to high frequency components to support the learning of criterial, highly predictive rules.     

Simulating correlated multivariate nonnormal distributions: Extending the fleishman power method

A procedure for generating multivariate nonnormal distributions is proposed. Our procedure generates average values of intercorrelations much closer to population parameters than competing procedures for skewed and/or heavy tailed distributions and for small sample sizes. Also, it eliminates the necessity of conducting a factorization procedure on the population correlation matrix that underlies the random deviates, and it is simpler to code in a programming language (e.g., FORTRAN). Numerical examples demonstrating the procedures are given. Monte Carlo results indicate our procedure yields excellent agreement between population parameters and average values of intercorrelation, skew, and kurtosis.     

Interrelations that foster learning: An investigation of two correlational studies

The theoretical tenets of academic engagement, as outlined by Schaufeli and colleagues, have received limited attention. There is credence to indicate that Schaufeli et al.'s conceptualization has educational implications. Extending this avenue of inquiry, we report two longitudinal studies that explore the motivation‐related attributes of engagement within the framework of self‐efficacy. A number of research questions were developed for examination—for example, does enactive learning experience influence academic achievement, via students' engrossment (i.e. absorption) of a subject matter? Does students' sense of resilience and persistence (i.e. vigor) heighten their self‐efficacy beliefs for academic learning? For the two studies (Study 1: 311 Year 11 students; Study 2: 249 Year 12 students), utilizing different cohorts, we measured these constructs at multiple time points. Existing Likert‐scale inventories were administered repeatedly, and data collected were analysed using causal modeling procedures. MPlus 7.2 yielded a number of key findings—for example: (a) the positive impact of Time 1 enactive learning experience on Time 2 absorption and vigor, (b) the positive impact of Time absorption on Time 3 self‐efficacy, (c) the positive impact of Time 2 absorption on Time 4 achievement and (d) the positive impact of Time 1 self‐efficacy on Time 2 absorption and vigor.
