Analysing consumers' perceived differences in wild and farmed fish
(2015)Purpose - The purpose of this paper is to investigate consumers' attitudes and behaviours towards wild and farmed fish, in order to identify possible distinct consumer groups, and to examine potential linkages between ... -
Comparative modelling of multi-stage production-inventory control policies with lot sizing
(2003)We propose a unified modelling framework, based on a queuing network representation, for describing, comparing and contrasting classical and new multi-stage production-inventory control policies with lot sizing. The classical ... -
Convex Approximation Algorithms for Back-Pressure Power Control
(2012)Throughput-optimal multihop wireless network operation entails a key physical-layer optimization problem: maximizing a weighted sum of link rates, with weights given by the differential queue backlogs. This emerges in joint ... -
Corporate philanthropy in the US stock market: Evidence on corporate governance, value relevance and earnings manipulation
(2015)This study examines the financial attributes of corporate philanthropy derived from the agency motives for corporate giving. Further, this study assesses the value relevance of corporate giving and investigates the impact ... -
Cost of capital, audit and earnings quality under financial crisis: A global empirical investigation
(2015)This paper investigates the cost of capital and the changes of audit quality and earnings management influencing on it due to financial crisis of 2008. Using linear regression analysis, 137,091 firm-year observations from ... -
Duplicate record detection: A survey
(2007)Often, in the real world, entities have two or more representations in databases. Duplicate records do not share a common key and/or they contain errors that make duplicate matching a difficult task. Errors are introduced ... -
Dynamic Wireless Network Coding With Overhearing and Variable Channel Rates
(2015)We study a one-hop broadcast channel with two receivers. The receivers have side information obtained by overhearing wireless channels. The relay takes control decisions by coding transmissions based on its knowledge of ... -
Estimating the optimal order quantity and the maximum expected profit for single-period inventory decisions
(2010)The paper considers the classical single-period inventory model, also known as the Newsboy Problem, with the demand normally distributed and fully observed in successive inventory cycles. The extent of applicability of ... -
Evaluating alternative Frequentist inferential approaches for optimal order quantities in the newsvendor model under Exponential demand
(2013)Three estimation policies for the optimal order quantity of the classical newsvendor model when the demand is Exponentially distributed are evaluated in this paper. The evaluation is performed analytically for different ... -
gpDB: a database of GPCRs, G-proteins, effectors and their interactions
(2008)gpDB is a publicly accessible, relational database, containing information about G-proteins, G-protein coupled receptors (GPCRs) and effectors, as well as information concerning known interactions between these molecules. ... -
Impact of Hardy-Weinberg equilibrium deviation on allele-based risk effect of genetic association studies and meta-analysis
(2010)Deviations from Hardy-Weinberg equilibrium (HWE) in control subjects may bias the estimates of genetic effects in genetic association studies (GAS) and meta-analysis. A large empirical evaluation was carried out to evaluate ... -
Investigating Greek consumers' attitudes towards low-fat food products: a segmentation study
(2003)The present study aims at gaining a first insight into Greek consumers' attitudes towards low-fat food products. Although Greece, and in particular Crete, have enjoyed a great popularity in terms of the Mediterranean diet, ... -
Key challenges for the creation and maintenance of specialist protein resources
(2015)As the volume of data relating to proteins increases, researchers rely more and more on the analysis of published data, thus increasing the importance of good access to these data that vary from the supplemental material ... -
Marine invertebrate diversity in Aristotle's zoology
(2007)The aim of this paper is to bring to light Aristotle's knowledge of marine invertebrate diversity as this has been recorded in his works 25 centuries ago, and set it against current knowledge. The analysis of information ... -
A modular framework for implementing joint wireless network coding and scheduling algorithms
(2013)Intersession network coding (NC) can provide significant performance benefits via mixing packets at wireless routers; these benefits are especially pronounced when NC is applied in conjunction with intelligent scheduling. ... -
Novel Virtual User Models of Mild Cognitive Impairment for Simulating Dementia
(2015)Virtual user modeling research has attempted to address critical issues of human-computer interaction (HCI) such as usability and utility through a large number of analytic, usability-oriented approaches as cognitive models ... -
On the tradeoff between optimal order-base-stock levels and demand lead-times
(2008)We investigate the tradeoff between finished-goods inventory and advance demand information for a model of a single-stage make-to-stock supplier who uses an order-base-stock replenishment policy to meet customer orders ... -
Optimal overload response in sensor networks
(2006)A single commodity network that models the information flow in an arbitrary topology sensor field that collects and forwards information to a backbone through certain designated gateway nodes is considered. Resilient ... -
Towards the Adoption of Open Source and Open Access Electronic Health Record Systems
(2012)As the Electronic Health Record (EHR) systems constantly expand to support more clinical activities and their implementations in healthcare organizations become more widespread, several communities have been working ... -
The Use of Nutritional Supplements Among Recreational Athletes in Athens, Greece
(2011)Although the use of nutritional supplements by professional athletes and the benefits thereof have been extensively studied, information on recreational athletes' use of supplements is limited. This study investigated the ...
