Power and Influence

Like any form of human interaction and communication it is possible to view Social Media as a means for the powerful to influence and control the less powerful. But what is power on social media, how might we measure or affect it, and does it translate to the real world? In this lecture we will look at the philosophical definitions of power, and explore how it has been analysed in social networks and social media systems. We will also look at the characteristics of social networks that impact on power, including Homophily, Heterophily, CyberBalkanization and Thresholds of Collective Action. Finally we will ask what evidence there is that power in social media can affect what goes on in the real world, and explore some real and fictional examples of protest to see what the consequences of social media actually are on sometimes violent political debate.

Towards a Theoretical Understating of How to Study the State: Governmentality, Power and Governmental Regimes

Artículo teórico que se origina a partir de un proyecto más amplio que investiga la construcción del Plan Nacional del Buen Vivir 2013-2017 (PNBV 2013-2017) en Ecuador. Su primordial preocupación teórica es responder a la siguiente pregunta: cómo estudiar los procesos de formación del Estado en Ecuador desde el año 2008. El documento responde a esta amplia cuestión argumentando, a nivel general, que el Estado se reproduce en parte mediante la creación de espacios donde efectivamente puede intervenir en la sociedad. Este trabajo se refiere, por lo tanto, con el examen de las formas particulares en que los Estados penetran la sociedad a través de regímenes gubernamentales. En términos más específicos, este trabajo sostiene que los procesos de intervención del Estado pueden ser ampliamente entendidos por la observación de tres procesos complementarios e interrelacionados: a. La forma en la que el Estado busca legitimar su presencia en la sociedad; b. Prácticas gubernamentales: las formas en las que el Estado aprende, organiza, distribuye y en última instancia crea campos específicos de intervención; c. El ejercicio de diferentes y complementarias modalidades de poder. En base a los citados elementos analiza la construcción de un "régimen gubernamental".

The impact of market and supply configurations on the costs of tendering in the construction industry

The cost of tendering in the construction industry is widely suspected to be excessive, but there is little robust empirical evidence to demonstrate this. It also seems that innovative working practices may reduce the costs of undertaking construction projects and the consequent improvement in relationships should increase overall value for money. The aim of this proposed research project is to develop mechanisms for measuring the true costs of tendering based upon extensive in-house data collection undertaken in a range of different construction firms. The output from this research will enable all participants in the construction process to make better decisions about how to select members of the team and identify the price and scope of their obligations.

Subcontract and supply enquiries in the tender process of contractors

In the tender process, contractors often rely on subcontract and supply enquiries to calculate their bid prices. However, this integral part of the bidding process is not empirically articulated in the literature. Over 30 published materials on the tendering process of contractors that talk about enquiries were reviewed and found to be based mainly on experiential knowledge rather than systematic evidence. The empirical research here helps to describe the process of enquiries precisely, improve it in practice, and have some basis to support it in theory. Using a live participant observation case study approach, the whole tender process was shadowed in the offices of two of the top 20 UK civil engineering construction firms. This helped to investigate 15 research questions on how contractors enquire and obtain prices from subcontractors and suppliers. Forty-three subcontract enquiries and 18 supply enquiries were made across two different projects with average value of 7m. An average of 15 subcontract packages and seven supply packages was involved. Thus, two or three subcontractors or suppliers were invited to bid in each package. All enquiries were formulated by the estimator, with occasional involvement of three other personnel. Most subcontract prices were received in an average of 14 working days; and supply prices took five days. The findings show 10 main activities involved in processing enquiries and their durations, as well as wasteful practices associated with enquiries. Contractors should limit their enquiry invitations to a maximum of three per package, and optimize the waiting time for quotations in order to improve cost efficiency.

Market power and its effects on equilibrium in the food system

When food processors have conjectures about rival firms' responses, their profit functions can be used to estimate the degree of market power in the food system. The effects of this power are investigated analytically and through applying the results to the U.S. pork sector
