Book Description
"This experiment is the sixth in a series of system studies dealing with various aspects of air traffic control. The purpose was to evaluate the performance of a one-controller system with (a) an omnipresent clock-type identity code vs. (b) the absence of identity on the radar blips. Data were recorded for a total of 1267 movements of jet-type fighter and bomber aircraft, which were accepted at four different entry rates. Four experienced USAF controllers served in the study. No conflicts (failures to achieve specified separations) and no missed approaches occurred at the slowest input rate (an average of one aircraft every 105 sec.), but a few conflicts and go-arounds (about 3%) occurred at the higher rates. This decrease in safety margin was most notable at the highest rate (60-sec. separation). Measures of fuel consumption and control time in moving aircraft through a zone of 50-mi. radius around the GCA gate showed significant superiority for the system that provided aircraft identity. An analysis of communications from controllers to pilots also showed small reductions in communications under the identity condition."--Abstract.

Book Description
"The purpose of the experiment was to determine the effect of regularization of approach traffic in time, place, and sequence upon the safety and efficiency of a terminal system. Enroute flow-control facilities were simulated by arrivals at the terminal boundary. The terminal system was manned by a two-man pattern-feeder control team. Six pairs of experienced USAF controllers participated. The control zone included two landing fields and each controller handled aircraft destined for each of these fields. Data were recorded for a total of 2880 movements of mixed types. The results and conclusions of the experiment are as follows: 1. Traffic input regularization in time, place, and sequence relative to the controller who accepted the traffic had an insignificant effect on terminal system performance. 2. Human controllers can provide the flexibility necessary to accommodate widely varying input entropy."--Abstract.

Book Description
This book examines identity theory’s centrality within social psychology and its foundations within structural symbolic interaction, highlighting its links not only to other prominent sociological subfields, but also to other theoretical perspectives within and beyond sociology. The book provides a synthetic overview outlining the intellectual lineage of identity theory within structural symbolic interactionism, and how the “Indiana School” of identity theory and research, associated especially with Sheldon Stryker, relates to other symbolic interactionist traditions within sociology. It also analyses the latest developments in response to the push to integrate identity theory, which initially focused on role identities, with the study of personal, group and social identities. Further, it discusses the relationship between identity theory and affect control theory, providing a sense of the many substantive topics within sociology beyond social psychology for which the study of identity has important, sometimes underappreciated implications. The book concludes with a chapter summarizing the interrelated lessons learned while also reflecting on remaining key questions and challenges for the future development of identity theory.

Book Description
This book explores the new politics of class in 21st century Britain. It shows how the changing shape of the class structure since 1945 has led political parties to change, which has both reduced class voting and increased class non-voting. This argument is developed in three stages. The first is to show that there has been enormous social continuity in class divisions. The authors demonstrate this using extensive evidence on class and educational inequality, perceptions of inequality, identity and awareness, and political attitudes over more than fifty years. The second stage is to show that there has been enormous political change in response to changing class sizes. Party policies, politicians' rhetoric, and the social composition of political elites have radically altered. Parties offer similar policies, appeal less to specific classes, and are populated by people from more similar backgrounds. Simultaneously the mass media have stopped talking about the politics of class. The third stage is to show that these political changes have had three major consequences. First, as Labour and the Conservatives became more similar, class differences in party preferences disappeared. Second, new parties, most notably UKIP, have taken working class voters from the mainstream parties. Third, and most importantly, the lack of choice offered by the mainstream parties has led to a huge increase in class-based abstention from voting. Working class people have become much less likely to vote. In that sense, Britain appears to have followed the US down a path of working class political exclusion, ultimately undermining the representativeness of our democracy. They conclude with a discussion of the Brexit referendum and the role that working class alienation played in its historic outcome.
