Abstract R&D is one of the most important sources of knowledge and economic growth worldwide, and technology transfer is the principal means to access this knowledge. Nevertheless, market imperfections, externalities, and abusive behaviors have been used by some jurisdictions to justify the enactment of regulations on different contractual categories frequently used to implement this transfer of technology.

This article uses a series of fixed-ratio projections and scenarios to explore the potential for local residential energy conservation mandates and compact growth programs to reduce locally based CO2 emissions in eleven representative US metropolitan areas. Averaged across all eleven metros, residential energy conservation mandates could reduce residential CO2 emissions in 2030 by an average of 30 percent over and above 2010 levels. In terms of implementation, residential conservation standards were found to be goal-effective, cost-effective, scale-effective, and in the case of new construction standards, reasonably resistant to local political pushback. Local compact growth programs do not perform as well. If accompanied by aggressive efforts to get drivers out of their cars, compact growth programs could reduce auto-based 2030 CO2 emissions by as much as 25 percent over and above any emissions reductions attributable to higher fuel economy standards. Unaccompanied by modal diversion programs, the stand-alone potential for local compact growth programs to reduce auto-based CO2 emissions falls into a more modest range of 0 to 7 percent depending on the metropolitan area. Based on past performance, local compact growth programs are also likely to have problems in terms of their goal- and scale-efficiency, and their potential to incur political pushback.

This editorial deals with the issue of sustainability in relation to the development of the city in the 21st century. The main goal is to make an inquiry into Piecemeal vs Grand Planning Approaches to generating sustainable cities. The focus of the city is the human settlements. The issue of sustainability has been a concern for many planners, architects, urban geographers and social scientists. “Sustainability” is an old concept but has become a new solution criteria for generating liveable cities. The role of the professional is crucial in the development of cities to become more sustainable. It seems that development of cities, especially those in developing countries, in the post-modern age require a critical evaluation and updating of their existing housing and settlement policies and practices. They seem to neglect the development dynamics in fast-growing metropoles sometimes. While the natural phenomenon of urbanisation require piecemeal approach to spatial planning and development in Developing countries, their governments tend to adopt Grand policies of developed countries. Implementation of such policies with fujrthern use of high-tech often results in large wipe-outs in the city and social disintegration, following the replacement of existing neighborhoods. Physical and social integrity, as well as slow growth of settlements is a crucial start towards sustainable cities.

With the increase of the population recently, changes have occurred in the design and construction techniques of the buildings due to the insufficient building stock. With the development of science and technology, new construction techniques have emerged in the construction and design of structures. In the global population increase, high-rise buildings were built to meet the need for shelter and these structures were built with the development of technology. However, high-rise buildings have become the symbol of technological development for countries and cities. Since the 21st century, the construction of high-rise buildings in cities with different designs and new construction techniques has provided the development of architecture and engineering. It is important to design high-rise buildings in accordance with the culture and texture of the city. In addition, high-rise buildings should be built as structures resistant to natural disasters such as earthquakes, fires and floods. For this reason, the design and construction techniques of high-rise buildings have become a research subject in the field of architecture and engineering. The aim of this study is to examine the designs and construction techniques of high-rise buildings. In the first part of the study, the concept of high rise building and its historical development are discussed. In the second part of the study, the designs and construction techniques of high-rise buildings are investigated. In addition, the study was conducted to examine the high structure by giving examples from the world and Turkey. Within the scope of the study, literature researches such as domestic and international articles, books, published theses, web resources were conducted and data were collected. As a result of the examinations made within the scope of the study, it is important to select the building materials in accordance with the characteristics of the building materials in the design and construction techniques of high-rise buildings with the development of technology. Therefore, the architect should know the properties of the materials in the design of high-rise buildings and use them in accordance with the properties of the material in the construction of the buildings. In addition, increasing the height of the building by making aerodynamic designs in high buildings reduces the effect of the wind speed.

Coal-water slurry fuel is coming into use in heat generation facilities as an alternative to natural gas and heavy oil. The main advantage of coal slurry is its cost efficiency. Our project is devoted to improvement of heat generation using coal-water slurry fuel instead of investing in new construction of coal-burning boiler houses. As an example, we considered implementing this project in the city of Leninsk-Kuznetsky, Russia. The project implies partial burning of coal slurry along with conventional coal burning. This solution is cost efficient and environmentally friendly yet not requiring major heat generation equipment replacement or renovation. The total cost efficiency of the suggested project is estimated at least as 1.1 billion rubles per year.

A vast majority of traffic crashes in urban areas occur at signalized intersections. Roadway geometry, traffic control, adjacent land uses, and environmental factors at intersections often contribute to the high incidence of traffic crashes and injuries. A public-private partnership project to identify high-crash and high-risk locations in the city of Detroit was initiated in 1996. Eighteen candidate sites were selected, and an extensive engineering study was conducted to develop countermeasures to help alleviate the traffic crash problem at the selected sites. The Automobile Association of America, Michigan, was the private partner in this joint venture and, in partnership with the city of Detroit, was a major contributor to covering the cost of improvements. The selection of countermeasures was based on state-of-the-art methodology and analysis, and implementation of the selected countermeasures at some of the sites was undertaken as the initial phase of the project. A comprehensive before-and-after evaluation study was performed at three of the improved sites. The study revealed that the safety improvements that were implemented lowered both crash and severity experience. The differences between the before and after crash frequencies proved to be statistically significant. Additionally, a benefit-cost analysis at the study locations indicated extraordinary results. This research presents the evaluation study results and discusses the countermeasures and improvements that were the most successful in mitigating traffic crash problems at the selected study locations.

The Ichthys LNG Project is one of the most complex oil and gas developments attempted. It is three mega-projects in one: an onshore project, an offshore project, and a pipeline project. The onshore project is being developed in Darwin and involves two processing trains rated to produce a total of 8.4 million tonnes of LNG per year. Offshore, the central processing facility (CPF) will feature the world's largest semi-submersible platform. A substantial floating, production storage and offtake (FPSO) vessel, designed to hold more than one million barrels of condensate, will be stationed nearby. Both the CPF and FPSO will be permanently moored in an area notorious for cyclonic weather conditions and will be designed to withstand even the most extreme weather conditions for more than four decades. An 889 km subsea pipeline will link the Ichthys Field, 200 km off the Western Australian coast, to the onshore facilities in Darwin. This represents the longest subsea pipeline in the southern hemisphere and fifth longest in the world. A final investment decision for the project was announced in January 2012. This triggered intense construction activity and created hundreds of new construction jobs in Darwin and more globally. More than 4,000 direct jobs will be created at the peak of construction. An approved capital expenditure of $US34 billion by INPEX and the Ichthys Project joint venture participants shows a tremendous commitment to Australia. Since the discovery of the gas-condensate field in 2000, the Ichthys road has been one of identifying and overcoming geographical, political, technical, physical, financial, and commercial challenges. The Ichthys Project is a global effort, drawing on worldwide expertise to overcome these challenges and work towards first gas in late 2016.

Historians have extensively explored the topic of architecture in Mexico City in the 20th century. From the relationships between politics, public patrons, new construction technologies, and new idioms of modernism, the impressive story of architecture in this megalopolis continues to astound and captivate people’s imaginations. Architecture was a channel that politicians used to address housing, education, and health care needs in a rapidly growing city. Yet scholars have not been especially concerned with private construction projects and their influence on the process of shaping and being shaped by the visual representation of Mexico City. Private building projects reveal an alternative reality of the city—one not envisioned by politicians and public institutions. Private construction projects in the historic city center are particularly interesting due to their location. These buildings are built on ancient clay lakebeds and volcanic soil on which the Aztecs first built the city. Not only are these buildings located in the heart of the city, the buildings in the rest of the historic district are also sinking. Any building in a historic district that has withstood the test of time should be an object of interest to scholars. The Torre Latinoamericana is perhaps the only building in the historic district and the entire city that ceases to sink, and instead floats! Located on the corner of Madero and San Juan de Letrán, the building sits at the heart of history, culture, and ancient Aztec clay lakebeds. The Torre Latinoamericana was built between 1948 and 1956 and is one of the most important visual symbols of resilience and modernity in Mexico City today.
