Since 9/11 and the creation of the U.S. Patriot Act, the intrusion of government surveillance into the lives of ordinary Americans has become a topic of great concern to many citizens. While many Americans view surveillance as a necessity in the name of national security, the government is not the only organization conducting surveillance. As technological capacity increases, an increasing number of employers are implementing technologies that allow them to maintain vigilance over the actions of their employees in the workplace. Despite many attempts to implement surveillance technologies, there is little evidence that companies are any safer now than they were ten years ago. This paper demonstrates how System Dynamics modeling can be utilized to help model the insider threat as a system. It provides analysis of the non-linear affect of decision making, assessing the 2nd, 3rd, and 4th order impacts of decisions, and demonstrates the important impact of delays in the system. A mathematical model is presented and simulations are conducted to determine the likely affect of company decisions and individual agent behavior.

In recent years, a proliferation of central governmental projects has been taking place within the Chinese government bureaucracy. In order for us to understand this phenomenon, we need to examine both the bureaucracy and the project system. This article proposes three key features of the project system, which tends to be temporary, goal-oriented, and flexible, as well as innovative in institutional design. A comparison of these features with the basic elements of bureaucracy shows that underneath the superficial fusion of the two systems there is unavoidable tension. Given the fact that the Chinese bureaucracy lacks structural constraints and public participation in its decision-making process, projects seldom meet the target of an appropriate supply–demand equation. Tensions are particularly manifested in two areas: (1) projects are inter-departmental and temporary in nature while bureaucracy is always rigid and insular; and (2) projects are goal-oriented and flexible while bureaucracy is rule-oriented and hierarchical. In most cases, central governmental projects have to operate within the government bureaucracy, and thus we call the system a ‘bureaucratized project system.’ In our case study, we find that the bureaucracy resists the project integration reform because its power is being threatened even though it is apparently beneficial for project operations. We are not optimistic about the future of the project integration reform as the task has now been laid upon the already over-loaded and wrongly-motivated local governments while the state bureaucracy remains all powerful.

Abstract he construction industry is one of the industrial sectors with the lowest rates of fulfilment of contract deadlines, especially in developing countries. This fact has been the focus of considerable discussions seeking to identify the causes of the delays. The main purpose of this paper is to use factor analysis to identify the factors that are correlated with delay, contemplating exclusively residential real estate projects and using a city in the Brazilian Amazon as a case study. Based on the database from the government agency that authorises constructions in the city of Belém (City Planning Department - Secretaria Municipal de Urbanismo, SEURB) and data from construction companies, the study investigated 274 construction projects from the past 11 years. Factor analysis and work with the variables that can be identified and measured in the initial phase of the project, i.e., during the feasibility study, demonstrate that the physical characteristics of the apartments and the construction project are the primary causes for variations in construction delays; these causes have not yet been reported in the literature. We hope that the results of this study will contribute to more consistent forecasting of construction time, minimising the risk of delays.

Flooding is one of the problems that Jakarta faces every year. To handle the issue, the government took action to build the East Flood Canal. The canal construction is expected to reduce flooding, especially in the east and north region of Jakarta. However, the construction did not make the area immediately free of flood risk. Previous study (Susanti, 2017) showed that even with the existence of the East Flood Canal, potential inundations may still happen, specifically in the Cakung Lama area. In 2017, there were still several inundation points in the Sunter area, especially in Kelapa Gading. This research aims to identify the cause of inundations in the area by evaluating channel capacity in the micro drainage system in Kelapa Gading using hydrological model HEC-RAS 4.1.0 and WinTR. The simulation results showed that several channels in the system cannot accommodate the inflow, hence causing inundation in some areas in the Kelapa Gading area. According to the simulation results, it can be concluded that the micro drainage system in Kelapa Gading is not effective to accommodate the inflow.
