In this position paper we present a set of best practices for workflow design to prevent workflow decay and increase reuse and re-purposing of scientific workflows. MyExperiment provides access to a large number of scientific workflows. However, scientists find it difficult to reuse or re-purpose these workflows for mainly two reasons: workflows suffer from decay over time and lack sufficient m...

This study formulates a two-objective model by individually minimizing shipping costs and inventory costs to decide whether to route a shipment through a hub or directly to its destination. First, shipping and inventory cost functions are formulated for a multi-port calling route. Shipping costs include capital and operating cost, fuel cost and port charge, while inventory costs include waiting...

People often tacitly assume an egocentric perspective when describing spatial scenes, and then use ambiguous descriptions (e.g., “The bottle is on the left.”). However, they can also take an alternative perspective, for instance referencing an agent that is present in the scene to reduce ambiguity (e.g., “The bottle is on your right.”). In this experiment, participants viewed a computer screen ...

Ethics is a concept used by people in everyday life. Apart from ethics existing in the wider social environment (secular ethics), another form of ethics found in a specific environment has been supported, that of Christian Ethics. While secular ethics has been studied quite intensely through a variety of theories, the issue of Christian Ethics especially within the framework of Orthodox Church ...

Recent works have highlighted that civil wars can have transnational dimensions and diffuse through spatial patterns. Other authors have investigated the relationship between polities and civil peace. The aim of this paper is to study whether the study of civil peace can be linked with state capacity and its interactions with spatial and temporal dynamics. Though some authors have suggested tha...

The growth of the e-commerce sector has highlighted the importance of shipping fees. We empirically study the effects of shipping fees and marketing activities on customer acquisition, customer retention, and average expenditures using data from an online grocer. We find that shipping fees greatly influence order incidence rates and graduated shipping fees significantly affect average expenditu...

Mismanagement of routing and deliveries between sites of the same company or toward external sites leads to consequences in the cost of transport. When shipping alternatives exist, the selection of the appropriate shipping alternative (mode) for each shipment may result in significant cost savings. In this paper, the authors examine a class of vehicle routing in which a fixed internal fleet is ...

noise is one of the main parameters to be considered to achieve a healthy indoor ambience in ferries. therefore, the noise standards need to be more specialized and specifically based on real sampled data and case studies. in the present research, the noise levels in a ship, under different working conditions, were sampled and compared with those specified in the new and old standards. an initi...

What is a fiscal consequence of legislative term limits? We develop a legislative bargaining model that predicts a u-shaped relationship between the level of seniority within a legislature and government spending. The size of government spending decreases as the level of seniority increases from low tomoderate, while it increases as the level of seniority increases from moderate to high. The mo...
