UKERC Review of evidence for the rebound effect: Technical report 2: Econometric studies

This Working Paper examines the evidence for direct rebound effects that is available from studies that use econometric techniques to analyse secondary data. The focus throughout is on consumer energy services, since this is where the bulk of the evidence lies

UKERC Review of evidence for the rebound effect: Technical report 5: Energy, productivity and economic growth studies

This report forms part of the TPA’s assessment of evidence for a rebound effect from improved energy efficiency. Technical Report 5 focuses upon the relationship between energy, productivity and economic growth and examines the claim that improved energy efficiency will increase economy-wide energy consumption - the so-called ‘Khazzoom-Brookes postulate’

Supply chain management, 3rd party logistics & food quality & safety: evidence from Greece

The aim of this study was to examine whether or not the efficiency of the supply chain management affect the food quality & safety. We focused upon transportation, warehousing, and inventory management. We also examined why food companies choose to outsource logistics functions such as transportation and warehousing and to what extent outsourcing affected food quality & safety. We conducted a large scale quantitative survey during January to March 2005. We faxed 400 questionnaires to Greek food companies with more than 5 personnel. We got 79 usable questionnaires (response rate 19.8%). The data analysis showed that food companies have no doubt that improving food quality means increased market share and profits. Transportation & warehousing are the main cost drivers. The most significant problems of the logistics function are: (1) re-occurring failures to quality control (2) overdue expiration date (3) inefficiencies in product sorting and handling. 44% of the companies have a logistics department. 35% of companies reported that prefer to get 3rd party logistics; most of them are SMEs. 50% of Greek food companies have acquired ISO certification in production, transportation and warehousing. ISO 14001 is rarely used. Almost all companies reported that training of personnel is a factor of improving food quality

Cooperatives Quality: evidence from Greece

The study of the role and contribution of ISO 9000 QMS to the corporate strategic development and organisational change and performance improvement of the Greek Agrocoops, as well as the identification and analysis of the drivers and constraints of this system’s effective implementation and efficient use has and/or should have been the subject of increased attention in recent times, as the majority of these organisations face increasing financial and business operating problems over the last three decades, as it was identified in a collective work of Papageorgiou et al, published in “Syneteristiki Poreia” (volumes of years 2000-2003) and the re-configuration of their organisational practices and activities, referring to any management system adapted and applied – e.g. the ISO 9000 QMS, is considered a must for their business survival in the words of Arvanitoyiannis (2001). As a result of the aforementioned facts and due to his current professional status, the researcher decided to focus his DBA research on issues relating to the role and contribution of the quality management systems - and more particularly of the ISO 9000 Quality Management Systems - to the achievement of Greek Agricultural Cooperatives’ corporate strategic goals and organisational performance improvement through the improvement of their business processes. The critical examination of the ISO 9000 – QualityManagement Systems’ implementation process and use purpose by the Agricultural Cooperatives sector in Greece is the broad and general Topic of my Doctorate Research. It is mainly connected with the following two current issues: - on one hand, with the reanimation of the ongoing dialogue and debate concerning the perspectives of the Agricultural Cooperatives in Greece and the future status of the 15% of the country’s active population, which is occupied in the broader agricultural sector (Bank of Greece, 2002), and - on the other hand, with the ever increasing public concern, interest and demand for safer, healthier and quality enhanced food products and services all over the world (ICAP, 2002 and Arvanitoyiannis, 2000)

Flame Detection for Video-based Early Fire Warning Systems and 3D Visualization of Fire Propagation

Early and accurate detection and localization of flame is an essential requirement of modern early fire warning systems. Video-based systems can be used for this purpose; however, flame detection remains a challenging issue due to the fact that many natural objects have similar characteristics with fire. In this paper, we present a new algorithm for video based flame detection, which employs various spatio-temporal features such as colour probability, contour irregularity, spatial energy, flickering and spatio-temporal energy. Various background subtraction algorithms are tested and comparative results in terms of computational efficiency and accuracy are presented. Experimental results with two classification methods show that the proposed methodology provides high fire detection rates with a reasonable false alarm ratio. Finally, a 3D visualization tool for the estimation of the fire propagation is outlined and simulation results are presented and discussed.The original article was published by ACTAPRESS and is available here: http://www.actapress.com/Content_of_Proceeding.aspx?proceedingid=73

Privacy and Health Information Technology

The increased use of health information technology (health IT) is a common element of nearly every health reform proposal because it has the potential to decrease costs, improve health outcomes, coordinate care, and improve public health. However, it raises concerns about security and privacy of medical information. This paper examines some of the “gaps” in privacy protections that arise out of the current federal health privacy standard, the Health Insurance Portability and Accountability (HIPAA) Privacy Rule, the main federal law which governs the use and disclosure of health information. Additionally, it puts forth a range of possible solutions, accompanied by arguments for and against each. The solutions provide some options for strengthening the current legal framework of privacy protections in order to build public trust in health IT and facilitate its use for health reform. The American Recovery and Reinvestment Act (ARRA) enacted in February 2009 includes a number of changes to HIPAA and its regulations, and those changes are clearly noted among the list of solutions (and ARRA is indicated in the Executive Summary and paper where the Act has a relevant provision)

Video Based Flame Detection Using Spatio-Temporal Features and SVM Classification

Video-based surveillance systems can be used for early fire detection and localization in order to minimize the damage and casualties caused by wildfires. However, reliability of these systems is an important issue and therefore early detection versus false alarm rate has to be considered. In this paper, we present a new algorithm for video based flame detection, which identifies spatio-temporal features of fire such as colour probability, contour irregularity, spatial energy, flickering and spatio-temporal energy. For each candidate region of an image a feature vector is generated and used as input to an SVM classifier, which discriminates between fire and fire-coloured regions. Experimental results show that the proposed methodology provides high fire detection rates with a reasonable false alarm ratio
