Watch, listen and learn: Observing children’s social conduct through their communication
No full textThis paper argues for the use of conversation analysis (CA) and membership categorisation analysis (MCA) (Sacks, 1992) to investigate children’s social conduct. A majority of prior research in this area has tended to focus on limited theoretical perspectives situated in developmental psychology, resulting in a dichotomous presentation of either prosocial or antisocial behaviour (see Bateman & Church, 2008 for an overview). Although the use of predefined categories “antisocial” and “prosocial” may be helpful for the organisation of data, there is a concern that these pre-defined classifications lead to children themselves being categorised as either consistently prosocial or antisocial (for example Nelson & Crick, 1999). This view encourages stigma and the labeling of children rather than offering further insight into children’s social worlds (Bateman & Church, 2008). This problem represents a shortfall in information regarding the complexity of peer interactions and how they are locally managed by the children themselves, disregarding the range of social competencies engaged in by the participants.
Therefore a shift in theoretical approach is argued for here as this informs of how social order is produced through verbal and non-verbal communications between the participants themselves (Butler, Fitzgerald & Gardner, 2009; Sacks, 1992a; 1992b;). Analyzing children’s social conduct through observing their communication offers an innovative, theoretical shift which is becoming more valued in many different areas of early childhood and particularly for the study of social relationships in education. This paper will outline the concept of communication as perceived from an ethnomethodological (EM) perspective, provide a background to EM and conversation analysis (CA), discuss some findings from research and then discuss the practical application of these findings for practice
Bateman gradients from first principles
No full textIn 1948, Angus Bateman presented experiments and concepts that remain influential and debated in sexual selection. The Bateman gradient relates reproductive success to mate number, and Bateman presented this as the cause of intra-masculine selection. A deeper causal level was subsequently asserted: that the ultimate cause of sex differences in Bateman gradients is the sex difference in gamete numbers, an argument that remains controversial and without mathematical backup. Here I develop models showing how asymmetry in gamete numbers alone can generate steeper Bateman gradients in males. This conclusion remains when the further asymmetry of internal fertilisation is added to the model and fertilisation is efficient. Strong gamete limitation can push Bateman gradients towards equality under external fertilisation and reverse them under internal fertilisation. Thus, this study provides a mathematical formalisation of Bateman’s brief verbal claim, while demonstrating that the link between gamete number and Bateman gradients is not inevitable nor trivial

John Frederic Latrobe Bateman
No full textDurant la segona meitat del segle XIX, els treballs de l'enginyer anglès John Frederic Latrobe Bateman, especialista en obres hidràuliques, permetien fer efectiva la dessecació i la posada en conreu de les terres de S'Albufera, la major zona humida de Mallorca. Entre 1863 i 1896, la "New Majorca Land Company", la dessecació de S'Albufera i la fundació de la colònia agrícola de Gatamoix i Sant Lluis són el llegat de la colonitzacio anglesa a l'illa de Mallorca.It was during the second half of the XIX century that the accomplishment of the English engineer John Frederic Latrobe Bateman, a specialist in hydraulics, enabled the draining and cultivation of the Albufera lands, the largest wetland of Majorca. The "New Majorca Land Company", the draining of the Albufera and the founding of the agricultural settlements of Gatamoix and Sant Lluis are milestones of an era of British colonization on the island of Majorca between 1863 and 1896

Novel schemes for the optical manipulation of atoms and molecules
No full textThe range of atoms which can be cooled by lasers is limited to those which have a closed two level structure. Several schemes have been proposed which aim to extend this range by using coherent control of the particle momenta, but none have yet been demonstrated. We hope to implement these and other coherent manipulation schemes, and we begin with a system which is well understood and over which we can exert precise control. This thesis covers the design and construction of an experiment to demonstrate coherent manipulation of cold rubidium atoms collected in a magneto-optical trap. The lower hyperfine levels of these cold atoms very closely mimic the ideal two-level atom, and we use carefully crafted laser pulses to prepare, manipulate, and read their quantum state. The hyperfine levels are coupled using two fields whose frequency difference is equal to the hyperfine splitting. The way in which these Raman coupled levels can be used to emulate a two-level atom is explored, and the experimental apparatus used to create and control the driving fields is described in detail. The amplitude, frequency and phase of these fields is programmable, and complex manipulation schemes can be implemented merely by programming a computer. We have observed Raman transitions in the cold rubidium atoms, and the experimental methods used to detect these features amidst large experimental noise are discussed. Although we have not yet seen Rabi oscillations, we are confident that we can now have sufficient control to begin to implement simple interferometric sequences. However, there remain significant challenges if we are to coherently manipulate the momentum, and the prospects for such manipulation are discussed
Hanging in the balance: KIR and their role in disease
No full textThe killer cell immunoglobulin-like receptors (KIR) are a recently discovered family of activating and inhibitory receptors that control natural killer (NK) cell function. KIR exist as a diverse family of receptors that have evolved rapidly by both gene duplication and recombination events. These findings were unexpected for a family of genes involved primarily in the innate immune response. These findings together with the observation that several of these genes have human leukocyte antigen (HLA) class I ligands, have led to a flurry of investigation into how KIR participate in viral infections, autoimmune diseases and malignancies. This review summarizes the major features of these genes and discusses how they may be involved in both disease pathogenesis and its amelioration
