Quantum private queries (QPQ) is an important cryptography protocol aiming to protect both the user's and database's privacy when the database is queried privately. Recently, a variety of practical QPQ protocols based on quantum key distribution (QKD) have been proposed. However, for QKD-based QPQ the user's imperfect detectors can be subjected to some detector- side-channel attacks launched by...

Food and nutrition security are intimately interconnected, since only a food based approach can help in overcoming malnutrition in an economically and socially sustainable manner. Food production provides the base for food security as it is a key determinant of food availability. This paper deals with different aspects of ensuring high productivity and production without associated ecological h...

We examine the proper scope of public-private partnerships in the context of a project consisting of two tasks, building and operation of a facility. We investigate the optimal arrangement regarding bundling versus unbundling and private ownership versus public ownership. Like Bennett and Iossa (2006), we assume that the innovative activity in the building stage has impacts on, among other thin...

This paper contributes to the pursuit of socially sustainable water and sanitation infrastructure for all people by discovering statistically robust relationships between Hofstede's dimensions of cross-cultural comparison and the choice of contract award types, project type, and primary revenue sources. This analysis, which represents 973 projects distributed across 24 low- and middle-income na...

objectives this study is the first of its kind to determine the framework, advantages, and limitations of bot contracts for health care projects in selected countries. background advantages and limitations of build-operate-transfer (bot) contracts in various forms of public-private partnership (ppp) arrangements have not been studied. conclusions this study suggests that more information transp...

Public Administrative Review's Theory to Practice features exchanges among scholars and practitioners assessing what prominent theories and research in their areas of expertise have to say about the challenges, choices, and opportunities facing public administration today. This article summarizes 15 years of CTG research into the challenges of cross-boundary knowledge and information sharing in...

The education system in Pakistan is languishing in an abysmal condition. In the absence of appropriate and consistent policy, the continued depreciation of facilities and erosion of public credibility in the state system many parents are opting out of the state system and moving to the growing private sector. The growth of the non-state sector in education has been steady since denationalizatio...

In this contribution, we analyse the pattern of the so-called PIP (Partnerships and Public Initiatives) that have been approved between 2000 and mid-2003 in the POE framework. In particular, we will evaluate the extent of decentralisation that this new instrument has generated in competitiveness policy. Partnership approaches are a relatively recent phenomenon, but partnerships have received wi...
