This exposition explains how Elementary Theory works and how it has been developed over the last two-and-a-half decades. Both increased scope and heightened precision are covered.

Theoretic methodology is explained. Using that method formal models are constructed analogous to empirical events. Those models predict events, design experiments, and guide applications in the field.

There is a widely held belief in sociology that theory becomes more vague and imprecise as its scope broadens. Whereas broader generalizations are more vague than narrower ones, this exposition shows that abstract theory becomes more precise as its scope broadens.

Here implications and limitations are closely connected. Regarding implications, this exposition shows that scientific explanations and predictions are viable today in sociology but only when exact theory is employed. Regarding limitations, the theory and research included in this exposition make clear why the empiricist search for regularities that dominates sociological research is so very limited in its results.

This exposition demonstrates that theory is the method of all the sciences and in particular the science of sociology.

Protests surrounding the 2004 Republican National Convention (RNC) resulted in over 1,800 arrests. Scholarship on repression is divided about the likely impacts of arrests on subsequent activism. Interviews with RNC arrestees are used to examine potential effects. Findings offer twists to social movements and socio-legal hypotheses: (1) while many arrestees were less willing to protest after their arrest, for many of these individuals deterrence was selective, not wholesale; (2) many factors that were expected to neutralize repressive impacts either resulted in deterrence or set the stage for radicalization; and (3) individuals who were radicalized shared strong preparation for their arrest experience.

The contribution of lean construction techniques in sustainable construction cannot be over emphasised, as sustainable development is now enshrined in government policy. In addition, lean construction is now faced with the challenges of sustainable development, continuous improvement, waste elimination, a stronger user focus, increased value for money along with high quality management of projects and supply chains, and improved communications. This paper presents an exploratory study from extant literature and the results of the use of questionnaire survey among construction participants to explore the contribution of implementing lean construction techniques in sustainable construction.

Surveys of UK-based construction professional were conducted. The data collected were analysed with SPSS 19.0 version software using the percentile method, Cronbach ' s α reliability test, Kruskal Wallis test, Kendall ' s coefficient of concordance and one sample t-test.

Results from this study indicate that there are several benefits associated with implementation of lean construction and sustainable construction. The overall perspective of professionals within the construction industry, according to questionnaire survey, shows that benefits such as improved corporate image and sustainable competitive advantage, improved process flow and productivity, improvement in environmental quality and increased compliance with customer ' s expectations are realised following integration of principles of lean construction and sustainable construction within construction industry. Just-in-time, visualisation tool, value analysis, daily huddle meetings and value stream mapping are the most common lean tools/techniques for enabling sustainability. This study also identified several areas of linkage between lean and sustainability such as waste reduction, environmental management, value maximisation, and health and safety improvement among others.

The originality of this paper lies in its consideration of lean construction principles to better understand its impact on sustainable construction. This research contributes to the awareness of the benefits that can be derived from the implementation of lean construction in sustainable construction within the construction industry.
