Rapid economic growth and urbanization in developing countries lead to extensive construction activities that generate a large amount of waste. A challenge is how to manage construction waste in the most sustainable way. In the developing world, research on construction waste management is scarce and such academic knowledge needs to be responsive to actual practices in the industry in order to be implemented. As construction projects involve a number of participants and stakeholders, their participation and commitment can have a major influence on the goals of green and sustainable construction for urban development. This study provides a significant step in conducting a very first research of this kind in Thailand by aiming to investigate the level of construction stakeholders' commitment as well as the achievement of construction waste management in order to improve short-term practices and to establish a long-term strategic construction waste management plan. In this study, a structural equation model was employed to investigate the influence of factors that are related to environmental aspects, social aspects, and economic aspect of construction waste management. Concern about health and safety was found to be the most significant and dominant influence on the achievement of sustainable construction waste management. Other factors affecting the successful management of construction waste in Thai construction projects were also identified. It is perceived that this study has potential to contribute useful guidelines for practitioners both in Thailand and other developing countries with similar contexts. © The Author(s) 2012. Source

Airport benchmarking has become a popular tool used by economists and airport managers alike. Within academic circles, a number of studies emerged assessing the productivity and efficiency of airports. This paper surveys the methods, data, and findings of empirical research in order to learn from previous research, and to gain further understanding of the airport industry. Our survey reveals that while commercialisation and restructuring contributed to efficiency increases, findings on ownership and scale effects are inconsistent. Data availability generally proved to be a serious issue. However, substantial progresses in capturing the increasing heterogeneous character of airports were made over time. Source

This paper explores coordination and cooperation between different levels of governance in the EU Marine Strategy Framework Directive and the US National Ocean Policy. Both policies aim at overcoming the previous sectoral organization of the marine policy field by establishing integrated approaches. As in the EU and the US, competencies in marine policies are shared between different levels of governance, the proper implementation of the Marine Strategy Framework Directive and the National Ocean Policy to large parts depends on the common efforts of all levels involved. In this submission, the co-management approach is used to analyze the coordinative procedures throughout the policy processes in the EU and the US. It derives four criteria for effective shared management from the literature, which are then applied to the Marine Strategy Framework Directive and the National Ocean Policy. It appears that the EU and the US promote different consensus-oriented procedures: while in the EU, they are mainly part of the decision-making phase, in the US, they are mostly subsequent to the National Ocean Policy's adoption. © 2014 Elsevier Ltd.

In a recently published paper (Abuelma'atti, Analog Integr Circuits Signal Process 65:419-428, 2010) the start-up conditions for a class of sinusoidal RC oscillators are discussed. In this context, the validity of the well known Barkhausen condition for oscillation is challenged. In this comment some of the author's conclusions are critically reviewed and the applicability of the Barkhausen criterion is demonstrated. © 2011 Springer Science+Business Media, LLC. Source

A recently published paper (Singh, Analog Integr Circuit Signal Process, 62:327-332, 2010) dealing with the relationship between the Barkhausen condition for oscillation and the well known Nyquist stability criterion for systems with feedback is highly appreciated. However, it seems to be necessary to place some comments on it. The circuit examples presented in the cited paper as well as the conclusions will be critically reviewed. Apparently, there is still no sufficient oscillation condition. Therefore, the necessity to complete the existing oscillation criterion with a sufficient condition is emphasized. © 2010 Springer Science+Business Media, LLC. Source
