People with seafaring experience and skills are employed in the maritime sector of the UK economy in land-based jobs as well as in seagoing ones. This paper examines the balance of supply and demand in the land-based jobs market. It then considers the likely effects of a shortfall in the supply of British ships’ officers to fill net vacancies in jobs ashore, including the policy implications of...

Purpose of this paper This paper studies how companies can select a supply chain planning mechanism to improve the balance between material flow and information flow. Design/methodology/approach The methodology of the paper is an inductive case study approach. Coordination theory is used as a background for the paper. Based on a literature survey, determinants of the selection of a supply chain...

In five well-trained and five sedentary control subjects potential subendocardial blood supply was estimated from the diastolic pressure time index (DPTI) and myocardial oxygen demands from the tension time index (TTI) during a progressive near-maximal treadmill test. DPTI/TTi was used to assess the effects of training on myocardial oxygen supply/demand balance. DPTI/1TI was significantly highe...

Cerebral oxygenation is not always reflected by systemic arterial oxygenation. Therefore, regional cerebral oxygen saturation (rScO2) monitoring with near-infrared spectroscopy (NIRS) is of added value in neonatal intensive care. rScO2 represents oxygen supply to the brain, while cerebral fractional tissue oxygen extraction, which is the ratio between rScO2 and systemic arterial oxygen saturati...

This paper investigates how high-speed home Internet has impacted married women’s labor force participation. I estimate the net effect of individual Internet usage on labor supply using an instrumental variables strategy which exploits cross-state variation in supply-side constraints to residential broadband Internet access. Results indicate that married women who use the Internet are more like...

Various economic literatures address the question whether first-best prescriptions for government policy require modification because redistributive income taxation distorts labor supply and cannot achieve the distributive ideal. Perhaps second-best rules for public goods provision, corrective taxation, public sector pricing, and other government activity should reflect concerns about distribut...

In conventional wastewater treatment one of the main problems confronting the plant manager is the estimation of the organic carbon removal efficiency, from which a mass balance can be computed. This paper presents a simple, albeit approximate, solution to this problem via a soft sensor approach. The basic idea is to apply a set-point control to the dissolved oxygen in the aerated compartment, ...

Since the applications of logistics are generally positive for the efficiency of transport systems, it has been suggested that logistics are environmentally friendly, thus emerged the concept of “green logistics”. Greening supply chains aim to balance marketing requirements with environmental issues. To meet challenges, such as energy conservation and pollution abatement, enterprises have tried...

To the problem of being lack of transit network hierarchy theory, a research on public transit network hierarchy optimization based on residential transit trip distance is conducted. Firstly, the hierarchy standard of transit network is given, in addition, both simulating electron cloud model and Rayleigh distribution model are used to fit the residential transit trip distance. Secondly, from t...

With the emergence of plugin hybrid electric vehicles (PHEVs) and electric vehicles (EVs) in the automotive market, the rate of the demand for electric power supply may be higher than the projected level. Distributed power generation is a feasible solution to balance the demand and supply of the power industry. In this work, a conceptual model of a solar photovoltaic (PV) based distributed gene...
