Abstract

Analysis of the peculiar velocities of galaxies should take account of the uncertainties in both redshifts and distances. We show how this can be done by a numerical application of the action principle. The method is applied to an improved catalog of the galaxies and tight systems of galaxies within 4$h_{75}^{-1}$ Mpc, supplemented with a coarser sample of the major concentrations at 4$h_{75}^{-1}$ Mpc to 20$h_{75}^{-1}$ Mpc distance. Inclusion of this outer zone improves the fit of the mass tracers in the inner zone to their measured redshifts and distances, yielding best fits with reduced $\chi ^2$ in redshift and distance in the range 1.5 to 2. These solutions are based on the assumption that the galaxies in and near the Local Group trace the mass, and a powerful test would be provided by observations of proper motions of the nearby galaxies. Predicted transverse galactocentric velocities of some of the nearby galaxies are confined to rather narrow ranges of values, and are on the order of 100 km~s$^{-1}$, large enough to be detected and tested by the proposed SIM and GAIA satellite missions., Comment: 11 pages, 8 figures, Submitted to ApJ

21. Sri Lanka

Author

Stai, P, Schulenkorf, N, Godfrey, J, and Phelps, S

Abstract

While it is recognised that volunteers can have a significant impact on the operations of sport organisations, previous research has not focused on the motivations and experiences of overseas volunteers in sport-for-development (SFD) settings. In addressing this issue, this chapter reflects on an empirical study around motivations and experiences of international SFD volunteers in post-war Sri Lanka.

22. Fitness industry self-regulation: institutional or by choice?

Author

MacFarlane, JD, Phelps, S, Schulenkorf, N, MacFarlane, JD, Phelps, S, and Schulenkorf, N

Abstract

© 2019, Emerald Publishing Limited. Purpose: The purpose of this paper is to document and explore the perceptual motivations for voluntary and continued affiliation with a fitness industry register by its affiliates (“members”) and non-affiliates (“non-members”). The formation of fitness industry registers to impart self-regulation is a common global occurrence. Their sustainment, however, is reliant on the motivations and voluntary support of industry members. Limited work has been done in this area. Design/methodology/approach: This qualitative study uses the interpretive research paradigm, involving semi-structured interviews with 12 Auckland, New Zealand, fitness centre managers, industry associations, New Zealand Register of Exercise Professionals (Reps NZ) and Fitness New Zealand. Lenox’s (2006) participation-contingent benefits framework provides the necessary lens to explore the perceptual motivations behind participation/non-participation by fitness centres with an industry self-regulatory system (i.e. Reps NZ). Findings: Whereas participation-contingent benefits are perceived minimal, and exceeded by affiliation limitations, there is institutional congruence for industry regulation to exist, thus creating institutional pressures that encourage affiliation and retention. Whereas affiliates choose to absorb the associated inconveniences of affiliation to “support” Reps NZ, non-affiliates question the register’s regulatory form, choosing to avoid the affiliation costs and limitations. Originality/value: This study lends further support that institutional development is crucial for inclusive, substantive and sustainable self-regulatory systems. Regardless of the perceived low return on participation-contingent benefits, industry self-regulation can be sustained if there is a desire by industry members to maintain the institutional notion that the regulation needs to exist.

25. Discovering Network Legitimacy in the Fitness Industry: A Case Study of REPs NZ

Author

MacFarlane, J, Phelps, S, and Schulenkorf, N

Abstract

Fitness industry registers may strategically attempt to enhance their field’s professional legitimacy via self-imposed regulation. Incorporating a conceptual framework of organisational legitimacy, this study identifies how 12 Auckland fitness centre managers perceive register affiliation. Representatives from the New Zealand Register of Exercise Professionals (REPs NZ) and Fitness New Zealand also contributed. Findings suggest participants are aware of the industry regulation concept, but opinions are mixed and member benefits are observed as minimal. Tensions exist between affiliates and non-affiliates regarding observed substantive/symbolic affiliate behaviours and the actual/perceived role of REPs NZ. Organisations act strategically and institutionally to acquire legitimacy through affiliation.

29. Initial Expansion of C4 Vegetation in Australia During the Late Pliocene.

Author

Andrae, J. W., McInerney, F. A., Polissar, P. J., Sniderman, J. M. K., Howard, S., Hall, P. A., and Phelps, S. R.

Abstract

Abstract: Since the late Miocene, plants using the C4 photosynthetic pathway have increased to become major components of many tropical and subtropical ecosystems. However, the drivers for this expansion remain under debate, in part because of the varied histories of C4 vegetation on different continents. Australia hosts the highest dominance of C4 vegetation of all continents, but little is known about the history of C4 vegetation there. Carbon isotope ratios of plant waxes from scientific ocean drilling sediments off north‐western Australia reveal the onset of Australian C4 expansion at ~3.5 Ma, later than in many other regions. Pollen analysis from the same sediments reveals increasingly open C3‐dominated biomes preceding the shift to open C4‐dominated biomes by several million years. We hypothesize that the development of a summer monsoon climate beginning in the late Pliocene promoted a highly seasonal precipitation regime favorable to the expansion of C4 vegetation.

Abstract

The allocation of resources within a system of autonomous agents, that not only have preferences over alternative allocations of resources but also actively participate in computing an allocation, is an exciting area of research at the interface of Computer Science and Economics. This paper is a survey of some of the most salient issues in Multiagent Resource Allocation. In particular, we review various languages to represent the preferences of agents over alternative allocations of resources as well as different measures of social welfare to assess the overall quality of an allocation. We also discuss pertinent issues regarding allocation procedures and present important complexity results. Our presentation of theoretical issues is complemented by a discussion of software packages for the simulation of agent-based market places. We also introduce four major application areas for Multiagent Resource Allocation, namely industrial procurement, sharing of satellite resources, manufacturing control, and grid computing., This survey has been written in the context of the activities of the AgentLink Technical Forum Group on Multiagent Resource Allocation (TFG-MARA)

34. Initial Expansion of C4Vegetation in Australia During the Late Pliocene

Abstract

Since the late Miocene, plants using the C4photosynthetic pathway have increased to become major components of many tropical and subtropical ecosystems. However, the drivers for this expansion remain under debate, in part because of the varied histories of C4vegetation on different continents. Australia hosts the highest dominance of C4vegetation of all continents, but little is known about the history of C4vegetation there. Carbon isotope ratios of plant waxes from scientific ocean drilling sediments off north‐western Australia reveal the onset of Australian C4expansion at ~3.5 Ma, later than in many other regions. Pollen analysis from the same sediments reveals increasingly open C3‐dominated biomes preceding the shift to open C4‐dominated biomes by several million years. We hypothesize that the development of a summer monsoon climate beginning in the late Pliocene promoted a highly seasonal precipitation regime favorable to the expansion of C4vegetation. This study documents for the first time that C4vegetation initially expanded on the Australian continent in the late Pliocene, several million years later than in Asia, Africa, North America, and South America. The expansion of C4plants displaced C3open habitat vegetation. Understanding the timing and sequence of expansion of C4‐dominated biomes enables us to better constrain the key environmental and evolutionary factors in their development and provides a basis for future conservation of these widespread and important biomes. Carbon isotope ratios of plant waxes reveal the onset of C4expansion during the late Pliocene in Australia, later than other geographic regionsPalynological analysis reveals increasingly open landscapes in the lead‐up to C4expansionNorthern Australian monsoon initiation linked to East Asian winter monsoon intensification is hypothesized as a driver
