An Affordance Based Approach to Decision Making in Sport: Discussing a Novel Methodological Framework

Decision making is a fundamental clement of any sport, particularly open, fast, dynamic team sports such as football, basketball and rugby. At the elite level, athletes appear to consistently make good decisions in situations that are highly temporally constrained. To further understand how this is done has been the aim of researchers within the perception-action field for several decades. The purpose of this article is to present novel contributions, both theoretical and methodological, that are pushing the boundaries of this area of research. The theoretical framework (Ecological psychology) within which the work is posited will be described, followed by a description of Virtual Reality (VR) technology and how it relates to the theoretical aims. Finally, an applied example will be summarised in order to demonstrate how the theoretical approach and the methodological approach come together in practice.

The Implications of Bach's Introduction of New Fugal Techniques and Procedures in the Well-Tempered Clavier Book Two

Among the fugues of the WTC II, there are some fugal techniques and procedures that were not explored in the first book. Here, the ‘fugal techniques’ include parallel entries (as used in the fugues in D-sharp minor, G minor and B-flat minor) and double counterpoint at the tenth or twelfth as well as fifteenth (as used in the fugues in G minor and B major). The ‘fugal procedures’, on the other hand, refer to meticulously planned multi-exposition architecture (as seen in the fugues in F-sharp minor exploiting two subsidiary subjects, and B-flat minor exploiting inversion and stretto) and a form in which the appearance of the subsidiary subject is gradually predicted in the fugal discourse (viz. C-sharp minor, G-sharp minor and B major). All these new ideas helped Bach to write more dramatic, more profound fugues for WTC II. The paper will consider how Bach came to acquire the new techniques and to use them in such ways, and what motivated him to adopt these new compositional approaches. Do they offer any clues for our better understanding of why Bach compiled the WTC II?

Regional Follow up of Late Preterm Neonatal Intensive Care Graduates: Methodological Considerations.

The aim is to guide researchers who are contemplating embarking on research by discussing the methodological challenges encountered in a retrospective follow-up study of three-year-old, late preterm infants (LPIs) who received neonatal intensive care (NIC) in Northern Ireland in 2006. The importance of effective research examining the longer term outcomes of infants admitted to NIC has received increasing recognition. Follow-up cohort and longitudinal studies have grown in number globally, yet the research methodology relating to follow up of NIC graduates is unclear. This paper highlights the methodological challenges of conducting retrospective follow-up research, from the initial planning stages through to the collection of data from the children, including identification of infants from a retrospective database, ethical issues, child-safety concerns and recruitment challenges. This paper creates an awareness of potential issues that may arise in follow-up research with NIC graduates. The paper also offers practical and effective examples of dealing with these issues, helping to ensure the smooth running of an ethical, professionally conducted, methodologically sound and clinically relevant follow-up study.
