Optical and infrared emission from discs, jets and nebulae associated with X-ray binaries
X-ray binaries are binary star systems in which a compact object (a neutron star or a black hole) and a relatively normal star orbit a common centre of mass. Since the discovery of X-ray binaries with the first X-ray telescopes in the 1960s, astronomers have tried to understand how these bizarre objects behave, and why. Some change in X-ray luminosity by eight orders of magnitude on timescales of days to months due to an increased transfer of mass from the star towards the compact object. Many X-ray binaries are detected at all observable frequencies, from radio to ,-rays. It has been found that many different sources of emission, which peak at different frequencies, are present in X-ray binary spectra and together they produce the observed broadband spectrum. However, disentangling these components has proved challenging. Much of the work in this thesis concerns disentangling the components that occupy the optiCal and near-infrared (NIR) region of the spectrum of X-ray binaries; possibly the region in which the relative contributions of the different components are least certain. In particular one component, the synchrotron emission from jets of outflowing matter, is found in this work to contribute ubiquitously to the optical and NIR light of X-ray binaries with relatively faint stars. These results confirm that the jets are powerful and in some of this work, observations of the jets interacting with the surrounding matter are used to infer their power. An introduction to the subject matter is presented in Chapter 1. Attention is given to the current thinking of the dominating optical and NIR emission processes, and to X-ray binaries that produce jets. In Chapters 2-6 I present a number of investigations into optical and infrared observations of X-ray binaries. Relations, patterns and general trends are discovered that have implications for not only the dominating emission processes but also for .the physical conditions and general behaviour of the inflowing and outflowing matter. In Chapter 7 I summarise the results and discuss follow-up work that could further our understanding of these objects.EThOS - Electronic Theses Online ServiceGBUnited Kingdo

Going Beyond Counting First Authors in Author Co-citation Analysis
The present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship

Designing R&D systems for mutual benefit
The aim of this final chapter is to provide the reader/practitioner with the requisite fundamentals to fashion a researching/learning/action system designed to meet the needs of different and often conflicting stakeholders. It is justifiably an action system because it has its foundations embedded in the world of experience. It is a learning system because it has the built-in capacity for reflection on experience and the wherewithall to recognise change or learning when it has occurred. It is a researching sytem because it offers contestable knowledge, knowledge which is open to robust and critical appraisal

Enthusiasm: developing critical action for second-order R&D
We were on a dust choked road somewhere between Wirrinya and Forbes in central western New South Wales. It was getting towards the end of an intense but absorbing week in which we were conducting the first ever 'rapid rural appraisal' (RRA) in Australia. This had involved visits to many farms and spending time with the farm families to hear about their histories of farming and the concerns and issues they now confronted. The impetus for the RRA had come from concerns about how and why particular research questions were asked and a strong feeling we held that the supposed clients of research, in this case farmers, were rarely active participants in formulating the research questions
