Development and validation of a questionnaire assessing volitional competencies to enhance the performance of physical activities in chronic low back pain patients

BACKGROUND: Motivation has long been emphasized as the most important determinant of action. However, there is a substantial gap between people's goals and their attainment. Patients may be motivated and yet unable to take action if their volitional competencies are insufficient. One of the important tasks of volition is goal-maintenance. Research has stressed the importance of a volitional tool, the implementation intentions. Implementation intentions indicate where, when, and how the action leading to the goal will be performed. Forming implementation intentions favours the execution of goal-directed efforts, and reinforces the relationship between intentions and behaviours. Results from various studies clearly suggest that volitional competencies and implementation intentions could play a role in low back pain (LBP) patients. However, there is at present no questionnaire allowing assessing the capacity of implementation intentions of physical activities in LBP patients. METHODS/DESIGN: This study will develop such a questionnaire, using a 3-step approach. A first qualitative step to build categories and generate items; 30 patients suffering chronic LBP will be invited to participate in semi-structured interviews; verbatim and derived items will then be submitted to a panel of experts, using a Delphi method; a second quantitative step to examine the properties of items, and determine the factorial structure of the questionnaire; 100 patients suffering chronic LBP will be recruited to respond to this phase; and third, preliminary psychometric analyses (item-scale correlations, construct validity, reliability); 180 chronic LBP patients will be recruited for this phase of the study. The relationships between implementation intentions and variables affecting physical activity on chronic LBP patients, i.e. pain, physical capacities, fear-avoidance beliefs, kinesiophobia, work status, and level of physical activity will be considered. DISCUSSION: Developing a questionnaire to assess implementation intentions would allow investigating the role of these intentions in the transition from acute to chronic LBP. The results of this study should contribute to the understanding of the psychological processes at stake in the development of chronic LBP, and in particular to the identification of factors eventually favouring patients' participation in and adherence to active physical treatments

Redefining professional identity: the voice of a language teacher in a context of collaborative learning

Following a narrative and biographic approach, in this study, we present the case of an in-service language teacher and her professional learning trajectory in the context of the project ‘Languages and education: constructing and sharing train- ing’. This project aimed at the construction of a collaborative teacher education context for learning and transformation of experiences, views and practices in language education, and involved teachers, teacher educators and researchers. Based on a single case study, the analysis tries to disclose the teacher’s discur- sive displacements as hints of professional transformation while she reinterprets the learning taking place in the collaborative education process. The signs of change are visible in the way she constructs meanings regarding her professional identity, re-identifies her mission as a language teacher and reconsiders her pro- fessional identity. Finally, we reflect upon how collaborative teacher education scenarios may foster teachers’ personal professional learning and renewed self- images

Can sclerotium size of Sclerotinia sclerotiorum be used as a predictor of susceptibility to Coniothyrium minitans ?

Here, we investigated a possible relationship between the level of in vitro susceptibility of the strains and the morphological traits of their sclerotia, with the aim of providing a simple predictive tool for field assessment. We focused on the average thickness of whole sclerotia and on that of the melanised cortical tissue that the mycoparasite needs to penetrate to colonize the medullar tissue. Significant differences were found among strains, with ranges of 0.80-1.72 mm and 51-84 μm, respectively, for sclerotium size (P 0.26; R² C. minitans in inoculated sclerotia but not to other susceptibility indices. These results suggest that other factors (possibly related to the biochemical composition of the tissues) play a determinant role in susceptibility of sclerotia to C. minitans. As a high level of intra-strain variability was observed (both in terms of morphological traits and susceptibility of sclerotia), work is under way to characterize individually larger numbers of sclerotia for selected strains

POLTERGEIST PHENOMENA IN CONTEMPORARY FOLKLORE

The article deals with instances of the supernatural in Romanian urban legends, namely what we call the strigoi , or poltergeist. Usually, folklorists tend to exclude the supernatural f rom the category of urban legends, however we have decided to take these accounts into consideration based on the fact that the transmitter, the narrators do not distinguish between these elements and the rest of contemporary legends and today’s popular cu lture abounds in such accounts
