Experiences relating to the InternationalMasters in Rural Development from the Technical University of Madrid (Universidad Politécnica de Madrid, UPM), the first Spanish programme to receive a mention as a Registered Education Programme by InternationalProject Management Association (IPMA) are considered. Backed by an educational strategy based on Project-Based Learning dating back twenty years, this programme has managed to adapt to the competence evaluation requirements proposed by the European Space for Higher Education (ESHE). In order to do this the training is linked to the professional qualification using competences as a reference leading to the qualification in project management as established by the IPMA.

Recent research has shown large differences between the expected and the actual energy consumption in buildings. The differences have been attributed partially, to the assumptions made during the design phase of buildings when simulation methods are employed. More accurate occupancy profiles on building operation could help to carry out more precise building performance calculations. This study focuses on the post-occupancy evaluation of two apartments, one renovated and one non renovated, in Madrid within the same building complex. The aim of this paper is to present an application of the mixed-methods methodology (Creswell, 2007) to assess thermal comfort and occupancy practices used in the case studies, and to discuss the shortcomings and opportunities associated with it. The mixed-methods methodology offers strategies for integrating qualitative and quantitative methods to investigate complex phenomena. This approach is expected to contribute to the growing knowledge of occupants’ behaviour and building performance by explaining the differences observed between energy consumption and thermal comfort in relation to people’s saving and comfort practices and the related experiences, preferences and values.

Eukaryotic gene expression, reflected in the amount of steady-state mRNA, is regulated at the post-transcriptional level. The 5'-untranslated regions (5'-UTRs) of some transcripts contain cis-acting elements, including upstream open reading frames (uORFs), that have been identified as being fundamental in modulating translation efficiency and mRNA stability. Previously, we demonstrated that uORFs present in the 5'-UTR of cystic fibrosis transmembrane conductance regular (CFTR) transcripts expressed in the heart were able to modulate translation efficiency of the main CFTR ORF. Here, we show that the same 5'-UTR elements are associated with the differential stability of the 5'-UTR compared to the main coding region of CFTR transcripts. Furthermore, these post-transcriptional mechanisms are important factors governing regulated CFTR expression in the heart, in response to developmental and pathophysiological stimuli.

The black tern (Anous minutus) uses a semi-precocial growth strategy. Terrestrial locomotor capacity occurs soon after hatching, but pectoral limb development is delayed and flight is not possible until about post-hatching day 50. A growth series (hatchlings to fledglings) was used to explore how limb musculoskeletal development varied with body mass. In the pelvic limb, bone lengths scaled isometrically or with negative allometry. Gastrocnemius muscle mass and the failure load and stiffness of the tibiotarsus scaled isometrically. In the pectoral limb, pectoralis and supracoracoideus muscle masses increased with strong positive allometry that was mirrored by increases in wing bone strength and stiffness. Bending strength (σult) and modulus (E) remained fairly constant throughout development to fledging for all limb bones. The moment of inertia (I) scaled with negative allometry for the tibiotarsus and with strong positive allometry in the wing bones. Differences in σult and E of the tibiotarsus between pre-fledged chicks and adults was due, primarily, to increases in bone density rather than increases in the moment of inertia of the skeletal elements, whereas σult of wing bones was a function of increases in both bone density and I. Early development of functional pelvic limbs in tree-nesting birds is relatively unusual, and presumably reflects a familial trait that does not appear to compromise breeding success in this species.

Post‐colonial theories about liminality, hybridity, unhomeliness, and identity form a novel lens through which to re‐theorise educational development work. Applying these conceptual frameworks allows practitioners and the academics they work with the opportunity to problematise some of educational development’s colonial underpinnings and assumptions. They also enable an exploration of the states of betweenness that form educational developers’ identities and impact implicitly and explicitly upon the nature of their changing practices. This paper seeks to read educational development and research supervisor development in particular “against the grain”. It also seeks to illustrate these concepts through some vignettes of my academic development practice.

Objective: Mitral repair is increasingly performed in asymptomatic mitral regurgitation (MR). Previous work showed that pre-operative documentation of loss of contractile reserve (Cr) by exercise echo (ExE) may predict LV dysfunction early after repair. We sought the value of Cr in predicting late post-op LV dysfunction and clinical outcome. Methods: Pre-op ExE was performed in 41 pts with isolated MR without coronary disease undergoing repair. LV end-systolic and end-diastolic volumes were measured at rest and post-stress and EF was calculated using modified Simpson’s rule. Intact Cr was defined by >4% increment of stress compared with rest EF. During follow up (3±1 years), EF was serially assessed and occurrence of cardiac events was documented. Results: Cr was present in 19 pts (Cr+)(peak EF 76±7%) and absent in 22 pts (Cr-)(peak EF 56±11%, p
