This paper presents and responds to On the Heels of Ignorance, a sociological study which identifies five fundamental epistemological paradigm changes in American psychiatry in the service of its survival and details several tactics that have been employed to facilitate these professional reinventions. Issues raised in this presentation include the relationship between psychiatry, society and the state, and the nature and significance of psychiatric expertise. The dynamic of these relationships and the complexities of the required expertise create their own challenges for the advancement and professional accountability of the specialty. The conclusion suggests some future imperatives. [ABSTRACT FROM AUTHOR]

Like other scientific disciplines, sociology can be observed as a social system made up of researchers, institutions, journals and publishers. These relationships are established via conceptual communications which form networks that establish the way in which disciplined are organized. At present, the big data phenomena offers the capacity to use large data collections to analyse social processes. Big scholarly data sources offer sociology immense quantities of data useful to describe and study the evolution of scientific disciplines in detail. In this article we characterised the last thirty years of sociology through its publications in impact factor journals. To do this, we use data about the sociology journals from Journal Citation reports augmented with article information from Microsoft Academic Graph. The analysis starts by describing the journals, countries of origin, languages, publishers, the decades in which they appeared and their impact factor. After this, we evaluate the evolution of numbers of articles and citations as well as co-authorship and gender proportion. Subsequently, we establish four groups of journal types and study their differences in the previous dimensions using hypothesis tests. Finally, we represent the relationships between authors and journals using an affiliation network that allows us to detect groups of journals that form interesting thematic and geographic communities. The novelty of the work consists in having used a data source of the so called big scholarly data with more than 300 million publications. The paper also provides several strategies to select the data of interest among the millions of publications to reduce their dimensionality in order to represent them in the form of a network. The results show a discipline dominated by Anglo-Saxon countries and large publishing conglomerates. The most prominent journals dominate citations whilst methodological journals have a higher degree of co-authorship and thematic journals have the lowest gender bias. The affiliation network between authors and journals contains two large groups, one formed by the pioneering American journals together with quantitative methodological journals and another one made up of English and qualitative methodological journals.

The control of rail signalling is known to be highly dependent on local knowledge and local factors. It is also known to be highly cognitive in its nature involving a constant balancing of system performance within the constraints of safety. In the current paper, data generated through field work with signallers were used to understand the role of local knowledge, set against the background of an existing Local Knowledge Framework (Pickup et al., 2013) that was proposed to help determine the contents and mechanisms behind local knowledge in rail signalling. The field work included interviews with signallers and operations managers along with observations of signaller work. The results showed that the local knowledge framework needs to be expanded to include aspects related to the general public at user worked crossings and level crossings. In addition, the analysis highlights some of the issues with the transmission of local knowledge. The paper then discusses some of the gaps in the current framework, highlighting the importance not only of local knowledge for specific functions of signalling, but how these interact to support trade-offs to balance performance with safety. The implications for the design of signaller work are discussed. [ABSTRACT FROM AUTHOR]
