Breaking the core-envelope symmetry in p-mode pulsating stars

It has been shown that there is a potential ambiguity in the asteroseismic determination of the location of internal structures in a pulsating star. We show how, in the case of high-order non-radial acoustic modes, it is possible to remove this ambiguity by considering modes of different degree. To support our conclusions we have investigated the seismic signatures of sharp density variations in the structure of quasi-homogeneous models.Comment: 3 pages, 3 figures, accepted for publication in Astronomy and Astrophysic

Dynamical replica theoretic analysis of CDMA detection dynamics

We investigate the detection dynamics of the Gibbs sampler for code-division multiple access (CDMA) multiuser detection. Our approach is based upon dynamical replica theory which allows an analytic approximation to the dynamics. We use this tool to investigate the basins of attraction when phase coexistence occurs and examine its efficacy via comparison with Monte Carlo simulations.Comment: 18 pages, 2 figure

Optimising community development through corporate social responsibility : an examination of the tourism industry in Livingstone, Zambia : a thesis presented in fulfilment of the requirements for the degree of Doctor of Philosophy in International Development Studies at Massey University, Manawatu, New Zealand

This thesis explores the potential for corporate social responsibility (CSR) practices of hotel and lodge companies to contribute to community development. A critical review of relevant literature is followed by focused discussions of the CSR practices of these companies, their community engagement approaches for seeking community voices in CSR, and policy frameworks for promoting CSR and managing stakeholder relationships. The empirical domain is the practices of hotel and lodge companies on Mukuni community land in Livingstone, Zambia. The discussion in each of the main empirical chapters is based on the analysis of perspectives and experiences of participants. Primary data was collected by conducting document and website reviews, and interviews with senior government officials, hotel and lodge managers, the local tourism association, leaders of relevant local and international NGOs, and leaders from Mukuni communities. Data was also collected through group interviews, network mapping, and pairwise ranking and comparison analyses with community farmers and crafts traders. Site observation of some CSR projects in communities was also undertaken. Thematic analysis was applied to code and analyse data. A theoretical framework focusing on “ensuring equity in CSR through multi-stakeholder measures” was developed and applied to understand the findings. Study findings suggest that power relations are a critical issue in CSR when initiatives are carried out in poor communities. It is shown that dominant corporate power and traditional power and cultural influences of community leaders, coupled with weak policy frameworks for promoting CSR and managing stakeholder interactions, are the main factors that determine the effectiveness of CSR as a vehicle for community development. These findings show that although criticisms are justifiably targeted mainly at corporations, communities and government also fall short in a number of ways as parties in promoting CSR. In view of these findings, key stakeholders, including government, hotels and lodges and communities, are challenged to adapt their respective policies, structures, mentalities and practices to ensure equity in CSR. The study has shown that multi-stakeholder involvement in CSR can encourage equity and might be helpful in shifting CSR from reflecting company interests alone to interests and needs of communities. This argument is based on evidence that in some cases, measures that seek to encourage multi-stakeholder involvement in CSR have proved to contribute to promoting equity and to widely spreading opportunities and benefits. It has also been shown that the role of government and other stakeholders is important for improving the overall effectiveness of CSR as a vehicle for community development

Status of the Pacific Mackerel resource during 1996 management recommendations for the fishery

The California fishery for Pacific mackerel (Scomber japonicus) has declined precipitously since 1990. Statewide landings during 1995 continued the downward trend, and totaled only 9,185 short tons. During the last few years, the principal cause of reduced catches has been low biomass and poor availability on the traditional fishing grounds in southern California waters. Cannery closures since 1993 may have also affected demand. Several sources of information are available on the status of the Pacific mackerel stock, all of which suggest a decline in stock biomass compared to the late 1970's and 1980's. Landing statistics, available since 1978 for both the U.S. and Mexican fisheries, show reduced catches during recent years. Catch rates for the southern California Commercial Passenger Fishing Vessel (CPFV) fleet have also shown declining trends since the 1970's. Other fishery- independent data from spotter pilot aerial observations and California Cooperative Oceanic Fisheries Investigations (CalCOFI) ichthyoplankton surveys indicate lower abundance compared to the early 1980's. We used a tuned virtual population analysis (VPA) model called ADEPT to estimate Pacific mackerel biomass. The model finds the best statistical fit between fishery-based, age-structured biomass estimates and other data from aerial observations, plankton surveys, CPFV catch data, and a spawner-recruit relation. Based on the estimated number of fish in each year class during the last quarter of 1995 (including the 1995 year class), and using certain assumptions for expected fishing mortality during the first half of 1996, we project that the Pacific mackerel biomass will be 52,000 tons at the beginning of the 1996/97 fishing season, on July 1,1996. There is a large degree of uncertainty in our 1996 biomass estimate because the 1995 year class (fish of age one) comprises most of the biomass. The Fish and Game Code specifies that when the biomass is between 20,000 and 150,000 tons, the season's quota shall be 30 percent of the total biomass in excess of 20,000 tons. Using that formula and our projection for July 1,1996, we recommend a commercial fishery quota of 9,600 tons for the 1996/97 fishing season. (26pp.
