Service quality in postgraduate education
Quality Assurance in Education, 2008Co-Authors: Robert Angell, T W Heffernan, Phil MegicksAbstract:Purpose – Measuring Service quality in higher education is increasingly important for attracting and retaining tuition‐based revenues. Nonetheless, whilst undergraduates have received substantial academic exposure, postgraduate‐based research has been scant. Consequently, the objectives of this paper are threefold: first, to identify the Service Factors used by postgraduates in their quality evaluations. Second, to analyse the appropriateness of importance‐performance analysis (IPA) in the measurement of Service quality and, final, to provide a working example of IPA's application in a UK‐based university.Design/methodology/approach – Convergent interviews were used to elicit attributes of Service that were deemed important by taught postgraduate students. These findings were then tested using an online survey. Exploratory Factor analysis was used to group the Service attributes into latent “Service Factors”. Each Service Factor was then tested for Service quality using Martilla and James's IPA technique....

Service quality in postgraduate education
Quality Assurance in Education, 2008Co-Authors: Rebecca J Angell, T W Heffernan, Phil MegicksAbstract:Purpose - Measuring Service quality in higher education is increasingly important for attracting and retaining tuition-based revenues.

Design/methodology/approach - Convergent interviews were used to elicit attributes of Service that were deemed important by taught postgraduate students. These findings were then tested using an online survey. Exploratory Factor analysis was used to group the Service attributes into latent "Service Factors". Each Service Factor was then tested for Service quality using Martilla and James's IPA technique. Findings - About 20 Service attributes were educed from the qualitative stage. From these, four Service Factors emerged; being, academic, leisure, industry links and cost. Using IPA in a UK university, the findings suggest that the "academic" and "industry links" aspects of Service quality are the most critical to postgraduates. The paper's conclusions suggest that IPA is an appropriate tool for measuring Service quality in postgraduate education. Practical implications - Through the application of the IPA framework presented in this research, practitioners can successfully identify areas of Service priority and thus allocate appropriate resources to encourage continuous Service improvement. Originality/value - This research provides a valuable insight into the Service quality needs of the UK postgraduate segment and also a potential conceptual framework for policy makers to use when evaluating their Service delivery.

Service Factor assessment of a great lakes bulk carrier incorporating the effects of hydroelasticity
Marine Technology and Sname News, 2009Co-Authors: S E Hirdaris, Norbert Bakkers, Nigel White, P TemarelAbstract:This paper presents a summary of an investigation into the effects of hull flexibility when deriving an equiva- lentServiceFactorforasinglepassageofaGreatLakesBulkCarrierfromtheCanadianGreatLakestoChina. The long term wave induced bending moment predicted using traditional three-dimensional rigid body hydrodynamic methods is augmented due to the effects of springing and whipping by including allowances based on two-dimensional hydroelasticity predictions across a range of headings and sea states. The analysis results are correlated with full scale measurements that are available for this ship. By combining the long term "rigid body" wave-bending moment with the effects of hydroelasticity, a suitable Service Factor is derived for a Great Lakes Bulk Carrier traveling from the Canadian Great Lakes to China via the Suez Canal. THE number of published investigations on springing and whipping of Great Lakes bulk carriers is limited. Springing was first noticed by Matthews (1967), who highlighted that long ships of shallow draft and depth are comparatively flex- ible in longitudinal bending and become prone to two-node vertical hull vibration of periods of 2 s (or longer). The first theoretical study, presented by Goodman (1970), was based on linear strip theory. This approach did not predict success- fully the level of resonant frequencies possibly because of uncertainty in the hull internal damping and inaccuracy of the measured excitation wave spectrum. Cleary et al. (1971) carried out extensive measurements on a Great Lakes ore carrier. They recorded maximum bending stresses of 80 MPa, of which 30% were shown to entail significant springing. This phenomenon was observed in low sea states and was considered to be the main cause of fatigue cracking. The data confirmed a substantial increase in springing with increasing speed. Stiansen (1984) presented a comparison between numeri- cal predictions and full-scale measurements for three Great Lakes bulk carriers with approximate overall lengths of 305 m, 246 m, and 192 m. Although the springing contribu- tion increased with wave height for the first two ships, for the smaller vessel it was reduced in larger waves. The damp- ing ratio of the larger ship was estimated as 1.6% with a standard deviation of 0.6%. This paper presents a summary of an investigation into the effects of hull flexibility when deriving an equivalent Service Factor for a single passage of a Great Lakes bulk carrier from the Canadian Great Lakes to China. The long- term wave-induced bending moment predicted using tradi- tional three-dimensional rigid body hydrodynamic methods is increased due to the effects of springing and whipping by including allowances based on two-dimensional hydroelasti- city predictions. Including the effects of springing and whipping generates at least a double-peak response spec- trum that invalidates the standard long-term approach, as this is only valid for narrow-band Rayleigh random processes. The two-dimensional hydroelasticity analysis was used to investigate the sensitivity to whipping and springing responses across a range of headings and sea states. The analysis results were correlated with full-scale measure- ments that are available for this ship. By combining the long-term "rigid body" wave-bending moment with the effects of hydroelasticity, a suitable Service Factor was derived for a Great Lakes bulk carrier traveling from the Canadian Great Lakes to China via the Suez Canal.

Feasibility study for the estimation of Service Factors of a Great Lakes bulk carrier incorporating the effects of springing and whipping
2007Co-Authors: S E Hirdaris, Norbert Bakkers, Nigel White, P TemarelAbstract:This paper presents a summary of an investigation into the effects of hull flexibility when deriving an equivalent Service Factor for a GLBC. The long term wave induced bending moment predicted using traditional 3D rigid body hydrodynamic methods is increased for the effects of springing and whipping, based on 2D hydroelasticity predictions. The analysis results were correlated with full scale measurements that are available for this ship.
