E-service quality of online higher education reflects the student’s perception of quality of online exchanges across four dimensions: fulfillment, efficiency, system availability and privacy.  This study links e-service quality to intentions to remain loyal as mediated by perceived value in an online higher education environment.  AMOS is used to examine the structural model based on responses to a student self-report online survey (n=127).  Results indicate a strong causal linkage between e-S-QUAL and Loyalty Intentions as mediated by Perceived Value.  Further, the direct linkage between e-S-QUAL and Loyalty Intentions was found to be insignificant, substantiating the proposed full mediation model.

The spatial and temporal variability in the fish component of the diet of Antarctic fur seals (Arctocephalus gazella (Peters, 1875)) in the Atlantic sector of the Southern Ocean was examined using diet data from 10 sites in the region including a 13-year time series from South Georgia. The fish species composition in the diet at each site showed a strong relationship with the local marine habitat / topography. The absence of formerly harvested fish species indicates a lack of recovery of stocks of Notothenia rossii Richardson, 1844 at South Georgia and Champsocephalus gunnari Lönnberg, 1905 at the South Orkney Islands. At South Georgia, Protomyctophum choriodon Hulley, 1981, Lepidonotothen larseni (Lönnberg, 1905), and C. gunnari were the most important species in the diet between 1991 and 2004. Variability in the occurrence of C. gunnari was driven mainly by annual scale processes, particularly those that influence the availability of Antarctic krill (Euphausia superba (Dana, 1852)). The occurrence of the pelagic P. choriodon was primarily influenced by shorter-term water mass changes within the foraging range of the seals. The fish composition in the diet reflects differences in marine habitat / topography, as well as variability, at a range of time scales that reflect environmental variability and harvesting.

Abstract:The interests, responsibilities and opportunities of states to provide infrastructure and resource management are not limited to their land territory but extend to marine areas as well. So far, although the theoretical structure of a Marine Administration System (MAS) is based on the management needs of the various countries, the marine terms have not been clearly defined. In order to define an MAS that meets the spatial marine requirements, the specific characteristics of the marine environment have to be identified and integrated in a management system. Most publications that address the Marine Cadastre (MC) concept acknowledge the three-dimensional (3D) character of marine spaces and support the need for MC to function as a multipurpose instrument. The Land Administration Domain Model (LADM) conceptual standard ISO 19152 has been referenced in scholarly and professional works to have explicit relevance to 3D cadastres in exposed land and built environments. However, to date, very little has been done in any of those works to explicitly and comprehensively apply LADM to specific jurisdictional MAS or MC, although the standard purports to be applicable to those areas. Since so far the most comprehensive MC modeling approach is the S-121 Maritime Limits and Boundaries (MLB) Standard, which refers to LADM, this paper proposes several modifications including, among others, the introduction of class marine resources into the model, the integration of data on legal spaces and physical features through external classes, as well as the division of law and administrative sources. Within this context, this paper distinctly presents both appropriate modifications and applications of the IHO S-121 standard to the particular marine and maritime administrative needs of both Greece and the Republic of Trinidad and Tobago.Keywords: marine administration system (MAS); marine cadastre (MC); marine information data model; land administration domain model (LADM); ISO 19152; S-121 maritime limits and boundaries (MLB); marine rights; restrictions and responsibilities (RRRs)

Many countries have seen a significant increase in the number of high-rise and multi-story buildings with strata units with the shrinking availability of horizontal land space in urban areas. Most existing cadastres record tenure and associated information in a two-dimensional format, and therefore will need to be upgraded to 3D cadastres to facilitate the recording of title information for these strata units. The geospatial aspects of implementing a 3D cadastre require cost-effective, rapid, accessible, non-labor intensive, and accurate means by which complete data may be collected to model strata units. Existing data sources such as Building Information Models (BIMs) have been used to delineate these units. However, BIMs are not easily accessible in developing countries. There is no single spatial data source that can easily fulfill all the criteria of a 3D data source for mapping urban strata boundaries. However, leveraging multi-perspective and multi-sensor data can theoretically serve this purpose. In this paper, we report on research conducted to demonstrate the feasibility of using low cost and accessible cell phone data, integrated with higher accuracy terrestrial laser scan data, and drone aerial imagery to produce a multi-perspective 3D data source. It was found that the integration of these data sets as a 3D data source, resulted in absolute accuracies within centimetres and decimetres in the horizontal plane and within millimetres in the vertical plane. Overall, the integration of these three sources of data may be appropriate in meeting the needs for a low-cost source of 3D data.
