Adult learners on Access to Higher Education courses struggled with institutional and social structures to attend their courses, but transformed their identities as learners through them. Although asymmetrical power relationships dominated the intentional learning communities of their courses, their work was facilitated by collaborative cultures and supportive tutors, and students gained the confidence to construct their own emergent communities of practice for learning. The students attended seven further education colleges in the East Midlands of England. Data were collected by mixed methods within a social constructivist framework from students and their tutors.

Bacterial culture methods, e.g. Plate Counting Method (PCM), are a gold standard in the assessment of microbial contamination in multitude of human industries. They are however slow, labor intensive, and prone to manual errors. Dielectrophoresis (DEP) has shown great promise for particle separation for decades; however, it has not yet been widely applied in routine laboratory setting. This paper provides an overview of a new DEP microbial capture and separation method called Fluid-Screen (FS), that achieves very fast, efficient, reliable and repeatable capture and separation of microbial cells. Method verification experiments demonstrated that the FS system captured 100% of bacteria in test samples, a capture efficiency much higher than previously reported for similar technology. Data generated supports the superiority of the FS method as compared to the established Plate Counting Method (PCM), that is routinely used to detect bacterial contamination in healthcare, pharmacological and food industries. We demonstrate that the FS method is universal and can capture and separate different species of bacteria and fungi to viruses, from various sample matrices (i.e. human red blood cells, mammalian cells).
