The classic English case of Williams v Eady (1893) had, for over a century, supported a teacher acting in loco parentis when inflicting punishment on a child, so long as the punishment was reasonable and given in good faith. But in response to the European Convention on Human Rights, which calls for all to respect a child’s right not to be “subject to torture or to inhumane or degrading treatment” (Article 3), many countries have banned the practice of using corporal punishment in schools. This might even include the use of reasonable force to prevent a student from injuring others or causing damage to property if it is seen as a form of discipline or punishment. Schools, therefore, have a difficult task of striking a balance between providing a safe environment for the whole school community and a child’s individual rights. This paper gives an overview of the trends in the United States, Australia, New Zealand, England, Canada and Singapore concerning corporal punishment, and then discusses the implications for employing or banning corporal punishment as a disciplinary strategy. The discussion takes on a brief jurisprudential analysis of this issue: that is, whether, corporal punishment, if carried out reasonably, is seen as a proper form of discipline, ensuring a safe and disciplined environment in which the school community, as a whole, might operate. Is the teaching profession over regulated in the area of physical discipline? If so, would the continuation or reintroduction of corporal punishment make sense, or would it make education an even riskier business?

Purpose - Recently, Colac Otway Shire in Australia released its management plan for Lake Colac, claiming over-enrichment of the lake with nutrients and degraded water quality. This paper aims to investigate these claims by establishing a correlation between key water and ecological indicators and land uses.
Design/methodology/approach - Examines the correlation between impairment and stressors in Lake Colac. This was achieved by identifying the likely sources of pollutants into Lake Colac; identifying any existing monitoring program; and characterizing the water and sediment inputs. The likely impacts of increased nutrients and sediment levels on indigenous flora and fauna were also examined. The use of meiofauna (very small benthic metazoan animals) was investigated as an indicator of degraded sites. Plankton diversity as a measure of water health was also assessed.
Findings - Water quality in Lake Colac was found to vary both temporally and spatially, and exhibited low attainment against acceptable trigger values/objectives. At current levels the lake can be classified as poorly degraded. Likely sources of pollution were identified to be related to land uses in the catchments. The biota of the lake, investigated at four study sites, yielded a sparse, benthic macrofaunal assemblage that was dominated by oligochaetes. In contrast, an abundant and taxonomically diverse meiofaunal assemblage was noted. Future meiofaunal analyses are likely to resolve suitable biotic indicator species of free-living nematodes in response to land use and waterway threats specified in the study. Originality value - This work will provide a better understanding of integrated environmental systems to enable development of best management practices, thus transforming the way the land and water are used in the future. Following the present work, other key water and ecological indicators (increased dispersion and dominance of biological species) at five additional sites were studied. Alternative management options for the effluent generated at Colac Sewage Treatment Plant and possible ecological effects of each option were also evaluated. More recently, a sediment characterization study was also carried out at sensitive sites representative of locations where build up of sediments and algae outbreaks are reported. This will enable classification of sediment and evaluation of dredging options.

Analyzing GEM 2005 data, we confirm that entrepreneurship and economic development form a U-shaped curve. We seek to understand New Zealand’s large deviation from the modeled curve by factor-analyzing all countries’ deviations from the curve. We make recommendations that would move New Zealand toward the trend line and thus aid in increasing its level of economic development. Our findings indicate that measures that overprotect workers, spoil incentives, or indulge welfare passivity can stymie economic growth even in conditions of high entrepreneurial activity.

Abstract The purpose of this study was to identify place-specific dimensions of service quality in spectator sport settings and determine if the importance of these dimensions differed across cultures. The study was limited to the soccer industry and involved the collection of responses from identified soccer spectators to a range of items presented in a survey instrument. The survey was distributed to respondents face-to-face on a match day of the club they supported, or mailed to their home address. Responses were obtained from spectators from two clubs from Australia (n=277), one club from the USA (n=199), one club from the Netherlands (n=245) and one federation from Malaysia (n= 100). Based on the findings of a number of authors, six categories of potential place-specific dimensions of service quality in spectator sport settings were created and the research instrument contained a number of items that could be categorised under one of these headings. These categories were Home, Religion, Social facilitation, Sensory, Uncertainty of outcome, and Personal attention. In this thesis it was assumed that place-specific service quality issues are similar for sport spectators of different cultures, although differences in degree of importance of these dimensions (etic approach) were likely to emerge. In other words, although it was expected dimensions per country to be similar, differences in degree of importance of these dimensions were expected. Given the lack of confirmatory statistical evidence pertaining to the specific country samples, it was concluded that differences per country are likely to be more than just differences in degree. Both the overall structure and structures per country could not be confirmed, and hence the conclusion was drawn that differences in nature between the countries were present. In other words, what is a dimension of place-specific service quality in one country is not necessarily a dimension in another country. The results of a content analysis of ‘core component’ structures per country compared with a (full sample) core component structure delivered six components (referred to as place-specific dimensions of service quality) that were defined as Home, Hedonist, Religious follower, Safe atmosphere, Hospitality and Personal Attention. It was found that in most cases the cultural orientation of soccer spectators reflects the cultural orientation of the country as a whole as proposed by Hofstede (1991). However, in line with Huntington (1997), it was also argued that grouping people based on their country of origin as a proxy for their cultural orientation, will increasingly lead to flawed and incomplete research findings. As noted by Yoo etal. (1999), the identification of a person's cultural orientation is likely to deliver more direct results when measured at the individual level In that regard it is concluded that it may seem prudent to view Hofstede's dimensions of culture with increased conceptual scrutiny. Although having been replicated in multiple studies, it becomes increasingly unlikely that Hofstede's dimensions cover the complete spectrum of an individual person's cultural orientation. In conclusion, this study identified that soccer spectators (from a number of clubs) from Australia, the USA, the Netherlands and to a lesser extent Malaysia, perceive a range of place-specific service quality dimensions in spectator spoil settings to be important when visiting a soccer match. Before research into satisfaction with and value of place-specific dimensions of the spectator sport service product is initiated, it is pertinent the identified dimensions are further explored and confirmed in different country (culture) settings. The confusion that still exists about the place of the value concept (in relation to quality and satisfaction), where Holbrook (1994) defines quality as a type of value and Chelladurai and Chang (2000) argue that value is a type of quality, further underpins this necessity. It needs to be clear what are the targets of service quality before this information is integrated in larger holistic research frameworks. In the final section of the thesis a conceptual model for international services marketing research in the sport industry was presented as a first attempt to integrate the findings of this research and other researchers.

Routine sand dredging for alluvial diamonds at Oranjemund on the southern coast of Namibia exposed remnants of a long forgotten Portuguese merchant ship believed to have wrecked in the 1530s. The rescue excavations yielded over 40 tons of cargo consisting of thousands of gold and silver coins, tons of copper and lead ingots, and large quantities of ivory together with food refuse, part of personal possessions and the superstructure of the ship. This paper discusses the cargo from the shipwreck. The varying provenances show that overland inter-and intra-regional networks fed into the maritime trade between Europe and the Indian sub-continent. As such, the wreck is a lens through which we can view what was happening on the seas as well as on land. Finally we consider wider issues raised by this discovery relating to the protection and management of such material wherever it may be found in future.

Marine inshore communities, including biogenic habitats have undergone dramatic changes as a result of exploitation, pollution, land-use changes and introduced species. The Firth of Forth on the east coast of Scotland was once home to the most important oyster (Ostrea edulis Linnaeus, 1758) beds in Scotland. 19th and early 20th century fisheries scientists documented the degradation and loss of these beds, yet transformation of the wider benthic community has been little studied. We undertook archival searches, ecological surveys and shell community analysis using radioisotope dated sediment cores to investigate the history of decline of Forth oyster beds over the last 200 years and the changes to its wider biological communities. Quadrat analysis of the present day benthos reveal that soft-sediment communities dominate the Firth of Forth, with little remaining evidence of past oyster beds in places where abundant shell remains were picked up by a survey undertaken in 1895. Queen scallops (Aequipecten opercularis Linnaeus, 1758) and horse mussels (Modiolus modiolus Linnaeus, 1758) were once common within the Forth but have also markedly decreased compared to the earlier survey. Ouranalyses of shell remains suggest that overall mollusc biomass and species richness declined throughout the 19th century and early 20th century, suggesting broader-scale community change as human impacts increased and as habitats degraded. Inshore communities in the Firth of Forth today are less productive and less diverse compared to past states, with evidence suggesting that most of the damage was done by early bottom trawling and dredging activities. Given the pervasive nature of intensive trawling over the past 150 years, the kind of degradation we document for the Firth of Forth is likely to be commonplace within UK inshore communities.
