Analysis of growth and stable isotopes in teeth of male Australian fur seals reveals interannual variability in prey resources

To detect and monitor long-term ecosystem responses to environmental variability, managers must utilize reliable and quantitative techniques to predict future ecosystem responses. Canine teeth from 67 male Australian fur seals (aged 2-19 yr), collected at Seal Rocks, between 1967 and 1976, were measured for relative growth within the dentine growth layer groups (GLGs), as an index of body growth. Fluctuations in relative growth were apparent during 1956-1971, suggesting interannual variation in prey resources within Bass Strait. These were positively correlated with the Southern Oscillation Index and negatively with the Indian Ocean Subtropical Dipole, both on a 2 yr lag. The observed delay may reflect the time required for the nutrient cascade to filter through to the predominantly benthic prey of Australian fur seals. Stable isotope analysis (?15N/?13C) was also used to investigate whether fluctuations in growth were associated with differences in diet. Relative growth was found to be negatively correlated with ?15N, suggesting years of greater resource availability may be associated with individuals consuming proportionally more prey biomass of lower isotopic value. This study demonstrates that fluctuations in the dentine GLGs of male Australian fur seals are related to environmental parameters, suggesting variation in body growth is mediated by changes in prey resources

The experience of Singapore in raising awareness of natural and cultural resources

The city-state of Singapore has a major role in the urban development. Majority of the innovative projects are initiated by the government agencies. For this paper, I would like to highlight the two distinct themes of innovation that, I believe preoccupied the authority for its urban issues, they are innovation which concern nature and culture. Land in Singapore is scarce. Natural resources are strictly protected. At the same time they are challenged to return the maximum benefit to their own population. The water catchment area and the prime forest on the whole island is the most valuable natural resources to be preserved. The paper will demonstrate how Singapore challenges with its own resources (water and greenery) in which the holistic planning around these themes become more than just spaces of protection but integrated with the public space system and turned into more valuable spaces for the well being of its population. The second theme is the issue related to culture. Singapore's economy is the most advance compare to other Southeast Asian countries, however when it comes to culture and identity, the city state struggles with the over constructed image of branding Singapore's culture. The paper will discuss several examples around the theme of arts and culture, how the city state bench-mark itself with the world class cities. It is one of the most challenging topic in urban planning and policy making. It is worth discussing on its success and failure. We can learn form Singapore that innovation at the level of policy maker can be achieved in some urban aspects such as the management of natural resources and urban design projects related to it. However when it comes to the issue related to art and culture, the top down policy alone cannot assure the achievement of city's identity as it aspired. Tracing the historical development of the environmental and cultural policies of Singapore the paper intends to study and analyze various case studies reflecting these attempts of natural and cultural instillation. In the process of comparison of these two drastically contrasting actors and approaches, the paper will argue that it has mostly been driven by economic aims, and careful thought. The results have been limited and restrictive. Further arguing that 'creativity' is the essential factor of arts and culture, it evaluates the authenticity and the ultimate implications on cultural spirit.

Students use a 'just-in-time' approach to accessing online resources

Lecture notes and recordings, tutorial exercises, readings, study questions, revision quizzes, instructional videos and crosswords were provided online so that students who could not attend classes (flexible learners) were not disadvantaged. D2L's progress viewing tool was used to track student access to resources, class attendance was monitored, and a questionnaire asked about the value of the online resources for completing the unit. While students thought it was important to attend classes, attendance was low and centred on tutorials and practical's, rather than lectures. The main reason for non-attendance was employment. Students accessed most of the online resources immediately prior to tests rather than on a week-by-week basis. Both attenders and flexible learners indicated that lecture notes, readings, revision quizzes and study questions were the most useful resources. Attenders accessed online resources more than flexible learners. There was only a weak correlation between class attendance and successful completion of the unit.

An ontology-driven topic mapping approach to multi-level management of e-learning resources

An appropriate use of various pedagogical strategies is fundamental for the effective transfer of knowledge in a flourishing e-learning environment. The resultant information superfluity, however, needs to be tackled for developing sustainable e-learning. This necessitates an effective representation and intelligent access to learning resources. Topic maps address these problems of representation and retrieval of information in a distributed environment. The former aspect is particularly relevant where the subject domain is complex and the later aspect is important where the amount of resources is abundant but not easily accessible. Conversely, effective presentation of learning resources based on various pedagogical strategies along with global capturing and authentication of learning resources are an intrinsic part of effective management of learning resources. Towards fulfilling this objective, this paper proposes a multi-level ontology-driven topic mapping approach to facilitate an effective visualization, classification and global authoring of learning resources in e-learning.

An ontology-based learning resources management framework for exploratory e-learning

This paper presents an ontology-based conceptual framework for effectively managing exploratory e-learning resources. The proposed framework has five significant novel features including authentication of retrieved resources, automatic ontology-based query refinement, reuse-oriented management of retrieved resources, adaptive retrieval of learning resources based on the style and preference of individual learners, and synthesisation of retrieval and management activities for creating reusable learning repositories. The applicability of the framework is demonstrated using a sample fragment of an ontology developed in the database domain.

Suzhi development: Indigenous approaches to enhancing the quality of human resources

Purpose- This paper aims to examine the Chinese indigenous concept of suzhi ((ProQuest: Non US-ASCII text omitted)) by analyzing its historical evolution and its contemporary implications for human resource management (HRM) research and practice at the national and organizational levels.Design/methodology/approach- An integrated review of literatures in sinology, political science, anthropology and sociology concerned with suzhi-related research, combined with recent incidents associated with suzhi.Findings-Suzhi is an indigenous concept embedded in the centuries-long historical context of China.Suzhi development has been focused on three key dimensions, moral, physical and mental, as a way of building quality employees and citizens. Yet developing and quantifying the moral aspects ofsuzhi is more challenging than measuring its physical and mental dimensions. Linkingsuzhi development to human capital theory enriches the understanding of this indigenous concept at both organizational and national levels.Research limitations/implications- By analyzing a three-dimensionalsuzhi composite, the article offers an example of howsuzhi may be linked to human capital theory and identifies directions for future research.Originality/value- By analyzingsuzhi at organizational and national levels for HRM purposes, this article broadens thesuzhi literature from its place in the political sciences and social anthropology to encompass a theoretical analysis in HRM and development for the benefit of organizations and the society.
