Can oiled shorebirds and their nests and eggs be successfully rehabilitated? A case study involving the threatened Hooded plover Thinornis rubricollis in South-eastern Australia

Although shorebirds are detrimentally affected by marine oil spills, they are often overlooked during rescue and rehabilitation efforts. This note describes a rescue and successful rehabilitation effort of an oiled adult and a juvenile Hooded Plover (Thinornis rubricollis) in Victoria, south-eastern Australia, during an oil-spill which oiled almost 1% of the State’s population of this threatened beach-nesting species. Two birds requiring intervention were located, selectively captured, cleaned and released. Both have survived at least two years after the spill and have bred, with at least one successfully fledging young. The fledgling has also successfully bred. Two nests with eggs present during clean-up operations were protected and hatched successfully. This small case study indicates that at least some groups of breeding shorebirds, such as plovers and dotterels, can be effectively rescued and rehabilitated during oil spills, and hence should not be overlooked during such circumstances.

Pretend play, social competence and involvement in children aged 5-7 years : the concurrent validity of the child-initiated pretend play assessment

Background and aims: The aims of this study were to investigate the relationship between pretend play, social competence and involvement in school-based activities in children aged 5–7 years and to determine whether children's social competence and level of involvement could be inferred from their scores on the Child-Initiated Pretend Play Assessment.
Procedure: The pretend play skills of 41 primary school-aged children aged 5–7 years were assessed on a one-on-one basis. Classroom teachers of the children assessed the children's social competence using the Penn Interactive Peer Play Scale and their involvement in school based activities using the Leuven Involvement Scale for Young Children.
Main findings: Significant positive relationships were found between elaborate pretend play and object substitution scores, involvement scores and peer play interaction scores (P < 0.05, P < 0.01). A significant negative relationship was found between elaborate pretend play scores, and social disconnection and social disruption scores (P < 0.05). Play deficit indicators were significantly negatively related to involvement scores (P < 0.01). This suggests that children with proficient pretend play skills are socially competent with peers and are able to engage in classroom activity. Children who scored poorly on the play assessment were more likely to have difficulty interacting with their peers and engaging in school activities.
Conclusion: Social competence and involvement skills are related to a child's ability to engage in pretend play. A child's social skills and ability to engage in school activities as assessed by teachers can be inferred from their scores on the Child-Initiated Pretend Play Assessment.

Barriers to cross-fertilization between populations of a widely dispersed Polychaete species are unlikely to have arisen through gametic compatibility arms-races

Although there are theoretical reasons to suspect that gametic incompatibility may develop readily among populations of broadcast spawning marine invertebrates, there have been very few studies documenting geographic patterns of interpopulation incompatibility for any species. To address this we determined how successfully individuals of the intertidal serpulid polychaete, Galeolaria caespitosa, can cross-fertilize within and among populations from across temperate Australia. Fertilization assays revealed asymmetrical differences between very distantly located populations from different coasts, with near-complete incompatibility between eggs from Sydney with sperm from Adelaide, but the reverse cross (Adelaide eggs, Sydney sperm) was reasonably compatible. Although that pattern was congruent with a clear difference in Cytochrome B sequences between worms on the south and east coasts of Australia, we also detected some indication of interpopulation incompatibility within the genetic grouping on east coast, between two populations separated by only 220 km. We then assessed whether commonly proposed gametic compatibility arms-races could account for these patterns. Our results suggest reduced gametic compatibility may reduce a female's maximum fertilization potential, resulting in a cost to this potential mechanism for reducing polyspermy. Consequently, the apparently rapid development of reproductive barriers here seems unlikely to have been driven by arms-races involving sexual conflict over fertilization rate.

An investigation on the risk perceptions of Australian property fund Managers

Recent empirical and analytical studies have demonstrated that downside risk appears as an intuitively appealing risk measure in which it is more consistent with investors’ behaviour. Conversely, qualitative studies into the behaviour of investors, particularly real estate investors, have been relatively limited. This study seeks to address this shortfall and aims to examine the perceptions of property fund managers towards risk. A survey was conducted to investigate the risk perceptions of property fund managers and determine whether they only require compensation for bearing with higher downside risk. The acceptance level of downside risk is also examined. The findings reveal that downside risk is more consistent with how investors individually perceive risk. However, there is also a gap between theoretical assertions and practice in which downside risk is not commonly used in the practice. The results give an insight into the knowledge base of property investors towards risk, particularly downside risk.

Sustainable property - the future of the New Zealand market

The New Zealand property industry has recently been introduced to the concept of sustainability. Even though targeted measures have been taken by the New Zealand Green Building Council and government, there is considerable hesitation and scepticism existing in the property market from both an investor’s and a building owner’s perspective. This paper discusses the results of an investigation into market perception of sustainable buildings from the investment community in New Zealand. Property investors from New Zealand were surveyed about their perception of sustainable buildings in New Zealand and their actions with regards to their own commercial portfolios, as well as the relationship between sustainability and property investment decisions.

Investor perception of the business case for sustainable office buildings : evidence from New Zealand

Over recent years the global market for sustainable commercial property has been growing in importance, with rapid growth occurring overseas that has led to substantial changes in the property markets. The New Zealand property industry has been recently introduced to the concept of sustainability, and although still at an early stage is already noticing the accelerating uptake of sustainability in the industry. Although certain measures have been taken by the New Zealand Green Building Council and government mandates, there remains still a common assumption that there is considerable hesitation and skeptism in the market from both an investor’s and a building owner’s perspective.

The research presented in this paper reports on the results of an investigation into the market perception toward sustainable buildings from the investment community in New Zealand. Property developers and investors from New Zealand were surveyed about their perception of sustainable buildings in New Zealand and their actions with regards to their own commercial portfolios, as well as the impact sustainability is having upon investment decisions. This paper presents the results of research conducted into the relationship between the elements of sustainability and the market value of an office building. The paper provides an insight into the rapidly evolving area of sustainability and office buildings, with the emphasis placed on the valuation process that seeks to assess a hypothetical purchaser’s perspective of this relationship.

The role of the online teacher in supporting student learning: A case study

As teaching and learning environments for many tertiary courses move to online delivery, it is important to ensure effective student learning is still taking place. This paper presents a review of the current literature on the roles of the teacher and e-tutor in e-learning environments. The research presented here is a case study of a wholly online course in which the role of the etutors was examined. This was achieved through analysis of their online interactions with students from two separate offerings of the course. The study found that in this environment the main role undertaken by all e-tutors was a managerial one. Differences were also noted between the roles undertaken by casual e-tutors and faculty staff.

Listed property trusts and downside systematic risk sensitivity

Purpose: This paper aims to identify and examine the determinants of downside systematic risk in Australian listed property trusts (LPTs).

Design/methodology/approach: Capital asset pricing model (CAPM) and lower partial moment-CAPM (LPM-CAPM) are employed to compute both systematic risk and downside systematic risk. The methodology of Patel and Olsen and Chaudhry et al. is adopted to examine the determinants of systematic risk and downside systematic risk.

Findings: The results confirm that systematic risk and downside systematic risk can be individually identified. There is little evidence to support the existence of linkages between systematic risk in Australian LPTs and financial/management structure determinants. On the other hand, downside systematic risk is directly related to the leverage/management structure of a LPT. The results are also robust after controlling for the LPTs' investment characteristics and varying target rates of return.

Practical implications: Investors and real estate analysts should conscious with the higher returns from high leverage and internally managed LPTs. Although there is no evidence that these higher returns are related to higher systematic risk, there could be the compensation for higher downside systematic risk.

Originality/value: This study provides invaluable insights into the management of real estate risk in Australian LPTs with implications for REITs in other countries. Unlike previous studies of systematic risk in REITs or LPTs, this is the first study to assess downside systematic risk and explore the determinants of downside systematic risk in LPTs.
