This article reviews the New Public Management (NPM) literature in Central and Eastern Europe with the aim of assessing whether reforms have ‘worked’. Increasingly academics have tended to argue against the suitability of NPM instruments in this region. To understand the impact of this much-debated policy, we first propose a classification of the impacts of NPM geared to the realities of Centra...

People rely on online reviews to guide their purchasing behavior. According to industry research reports, a big proportion of consumers claim that their purchasing decision is largely influenced by online reviews (Deloitte 2007). In addition, consumers share these reviews with their family, friends or colleagues to make sense of their shopping experiences and deepen social connections (Peters a...

We build upon previous work out of UC Berkeley’s energy, controls, and applications laboratory (eCal) that developed a model for price prediction of the energy day-ahead market (DAM) and a stochastic load scheduling for distributed energy resources (DER) with DAM based objective [3]. In similar fashion to the work of Travacca et al., in this project we take the standpoint of a DER aggregator po...

This chapter focuses on an important, challenging and yet largely unaddressed problem in Wireless Sensor Networks (WSN) data communication: detecting cheating aggregators and malicious/selfish discarding of data reports en route to the Base Stations (BSs). If undetected, such attacks can significantly affect the performance of applications. The goal is to make the aggregation process tamper-res...

Background: Quality control for real-time spatio-temporal data is often presented from the perspective of the original owner and provider of the data, and focuses on general techniques for outlier detection or uses domain-specific knowledge and rules to assess quality. The impact of quality control on the data aggregator and redistributor is neglected. As sensor networks proliferate, multiple p...

The existing retail market arrangements for investment in distributed energy technologies, including household solar PV systems, are not well aligned with the economic value that these technologies can provide within the electricity industry. In particular, these commercial arrangements fail to account for temporal and spatial variations in costs and benefits across market participants. The stu...

Continuous aggregation queries over dynamic data are used for real time decision making and timely business intelligence. In this paper we consider queries where a client wants to be notified if the ratio of two aggregates over distributed data crosses a specified threshold. Consider these scenarios: a mechanism designed to defend against distributed denial of service attacks may be triggered w...

Federal energy regulatory commission (FERC) Order #2222 prescribes that distributed resources (DERs) with 100 kW or more capacity in aggregate should be allowed to participate organized electricity markets. Most aggregation is via a combination of disparate DER technologies such as solar, wind, storage, electric vehicles, and smart load units. Another stumbling block enabling participation DERs...

In online platforms, recommender systems are responsible for directing users to relevant content. order enhance the users’ engagement, adapt their output reactions of users, who are, in turn, affected by recommended this article, we study a tractable analytical model user that interacts with an news aggregator, purpose making explicit feedback loop between evolution user’s opinion and personali...

Promoting the development of renewable energies and the efficient and intelligent use of energy could be achieved through making adaptive consumer demands to energy supply. In this paper, we propose a mechanism based on three time scales, year, day and hour and three sets of agents, consumers, aggregators and providers to adapt consumption to production. We propose to use in this model the brea...
