The three delays as a framework for examining safe motherhood in Kafa zone, SNNPR, Ethiopia

The study examines delay as a crucial factor contributing to maternal mortality, using the conceptual framework of the Three Phases of Delay to explore factors that hinder the provision and utilisation of high quality, timely obstetric care in Kafa Zone, SNNPR, in Ethiopia. The Three Delays constitute the delay in deciding to seek medical care during an obstetric emergency, in reaching a medical facility, and in receiving suitable treatment in a health facility. Various aspects of the Three Delays are evaluated to examine problems of delay, transportation, and the referral system that is considered a vital element of the Ethiopian 'National Reproductive Health Strategy'.

Mother and toddler activity in the zone of proximal development for pretend play as a predictor of higher child IQ

This study investigated the pretend play of mother—toddler dyads in relation to later child IQ. Twenty-one toddlers were videotaped in monthly play sessions with their mothers, from age 8 to 17 months, and later assessed at 5 years of age on the Stanford-Binet IV. Children's and mothers' pretend play levels and frequencies were measured using Brown's (1997) Pretend Play Observation Scale. Dyadic play activity was analyzed using the conceptual frameworks of scaffolding and Vygotsky's Zone of Proximal Development (ZPD). Toddlers later assessed as having higher IQ demonstrated more rapid learning in the ZPD for pretend play and experienced earlier maternal transfer of responsibility for play. These findings support other evidence on the differential early development of high ability or gifted children and the role of caregiver interactions in that development.

Putting the Research to Use: This study provides evidence that gifted children show differential development, in this case more rapid learning, from the first year of life. It also demonstrates how responsive parental interactions can support this advanced development. For family and professional caregivers, the findings imply that optimum caregiving for the young gifted child involves interactions that are both responsive to individual potential and appropriately challenging. In regard to the methodological challenges of researching early giftedness, the study demonstrated that the constructs of the ZPD and scaffolding were useful frameworks for investigating early gifted development and caregiver influences on that development. Pretend play activity was also shown to be an effective measure and a useful context for the study of gifted development in infants and toddlers. It would be valuable for future researchers in this area to utilize similar approaches that are grounded in the unique developmental characteristics of young children, and that aim to account for the interactive contexts that are so important in children's lives. The field of gifted education, in general, would also benefit from an increased awareness and exploration of the role of play in the development of intellect, imagination and creativity.

In the green zone : 40 years with Colonel Qaddafi

Colonel Muammar Qaddafi has been the leader of Great Socialist People's Libyan Arab Jamahiriya since September 1969. After 40 years in control of his nation, Qaddafi is actually the world’s longest serving non‐monarchial head of state. This year’s anniversary makes it timely to review his four decades of rule. From being the leader of a successful military coup to being America’s bête noire of the 1980s and then the head of a much‐vilified rogue state under twenty‐seven years of UN sanctions, the mercurial Qaddafi has lately steered his nation to something of a rapprochement with the West, been elected to the chairmanship of the African Union and simultaneously had a very public falling out with some of his Arab leaders. This paper examines the highs and lows of Qaddafi’s leadership and where his small but prominent North African state may be heading.

Ecology of fish inhabiting the inter-tidal zone of Swan Bay, Victoria, Australia

Swan Bay is a shallow marine embayment of Port Phillip Bay, just north of Queenscliff, Victoria. It has been part of the Harold Holt Marine Reserves since 1977 and is a seagrass habitat. This study investigated the species of fish present in the inter-tidal zone of Swan Bay, collected information on their ecology, investigated the importance of Swan Bay compared to Port Phillip Bay as a nursery and/or breeding area and compared these results with those of similar seagrsss habitats. Field work was carried out monthly over a two year period, from April 1981 to April 1983, using beach seine nets at Swan Bay and Portarlington. Forty four species of fish were identified from Swan Bay and nineteen from Portarlington. Fish were most abundant during the summer and autumn months when seagrass growth was at a maximum and least abundant during winter due to the absence of seasonal residents and decreased numbers of permanent residents. Swan Bay was found to be an important nursery ground for two commercially-caught species: the Yellow-eye Mullet and the King George Whiting. Juvenile Yellow-eye Mullet were more numerous in Swan Bay than at Portarlington. Smell juvenile King George Whiting were more abundant at Portarlington than in Swan Bay where older juveniles were more numerous. The fish fauna of Swan Bay was found to be similar to western Port but the abundance of species varied. Atherinosome microstoma was the dominant species in terms of abundance and biomass. Diet was found to be different from that reported by Robertson (1979) at Western Port due to the different range of prey items.

Ecological value of riparian zones to birds in forest landscapes

Riparian zones are a characteristic component of many landscapes throughout the world and increasingly are valued as key areas for biodiversity conservation. Their importance for bird communities has been well recognised in semi-arid environments and in modified landscapes where there is a marked contrast between riparian and adjacent non-riparian vegetation. The value of riparian zones in largely intact landscapes with continuous vegetation cover is less well understood. This research examined the importance of riparian habitats for avifauna conservation by investigating the ecological interactions contributing to the pattern of bird assemblages in riparian and adjacent non-riparian habitats. Specifically, the focus is on the bird assemblages of riparian zones and those of adjacent non-riparian vegetation types and the influence that associated differences in resource availabilities, habitat structure and conditions have on observed patterns. This study was conducted in the foothill forests of the Victorian Highlands, south-east Australia. Mixed-species eucalypt (genus Eucalyptus) forests dominate the vegetation of this region. Site selection was based on the occurrence of suitable riparian habitat interspersed within extensive, relatively undisturbed (i.e. no recent timber harvesting or fire events) forest mosaics. A series of 30 paired riparian and non-riparian sites were established among six stream systems in three forest areas (Bunyip State Park, Kinglake National Park and Marysville State Forest). Riparian sites were positioned alongside the stream and the non-riparian partner site was positioned on a facing slope at a distance of approximately 750 m. Bird surveys were carried out during 29 visits to each site between July 2001 and December 2002. Riparian sites were floristically distinct from non-riparian sites and had a more complex vegetation structure, including a mid-storey tree layer mostly absent from non-riparian sites, extensive fine litter and coarse woody debris, and dense ground-layer vegetation (e.g. sedges and ground ferns). The characteristic features of non-riparian habitats included a relatively dense canopy cover, a ground layer dominated by grasses and fine litter, and a high density of canopy-forming trees in the smaller size-classes. Riparian zones supported a significantly greater species richness, abundance and diversity of birds when compared to non-riparian habitats. The composition of bird assemblages differed significantly between riparian and non-riparian habitats, with riparian assemblages displaying a higher level of similarity among sites. The strongest contributors to observed dissimilarities between habitat types included species that occurred exclusively in either habitat type or species with large contrasts in abundance between habitat types. Much of the avifauna (36%) of the study area is composed of species that are common and widespread in south-east Australia (i.e. forest generalists). Riparian habitats were characterised by a suite of species more typical of wetter forest types in south-east Australia and many of these species had a restricted distribution in the forest mosaic. Some species (7%) occurred exclusively in riparian habitats (i.e. riparian selective species) while others (43%) were strongly linked to these habitats (i.e. riparian associated species). A smaller proportion of species occurred exclusively (2%) in non-riparian habitats (i.e. non-riparian selective species) or were strongly linked to these habitats (10%; i.e. non-riparian associated species). To examine the seasonal dynamics of assemblages, the variation through time in species richness, abundance and composition was compared between riparian and non-riparian sites. Riparian assemblages supported greater richness and abundance, and displayed less variation in these parameters, than non-riparian assemblages at all times. The species composition of riparian assemblages was distinct from non-riparian assemblages throughout the annual cycle. An influx of seasonal migrants elevated species richness and abundance in the forest landscape during spring and summer. The large-scale movement pattern (e.g. coastal migrant, inland migrant) adopted by migrating species was associated with their preference for riparian or non-riparian habitats in the landscape. Species which migrate north-south along the east coast of mainland Australia (i.e. coastal migrants) used riparian zones disproportionately; eight of eleven species were riparian associated species. Species which migrate north-south through inland Australia (i.e. inland migrants) were mostly associated with non-riparian habitats. The significant differences in the dynamics of community structure between riparian and non-riparian assemblages shows that there is a disproportionate use of riparian zones across the landscape and that they provide higher quality habitat for birds throughout the annual cycle. To examine the ecological mechanisms by which riparian assemblages are richer and support more individual birds, the number of ecological groups (foraging, nest-type and body mass groups) represented, and the species richness of these groups, was compared between riparian and non-riparian assemblages. The structurally complex vegetation and distinctive habitat features (e.g. aquatic environments, damp sheltered litter) provided in the riparian zone, resulted in the consistent addition of ecological groups to riparian assemblages (e.g. sheltered ground – invertebrates foraging group) compared with non-riparian assemblages. Greater species richness was accommodated in most foraging, nest-type and body mass groups in riparian than non-riparian assemblages. Riparian zones facilitated greater richness within ecological groups by providing conditions (i.e. more types of resources and greater abundance of resources) that promoted ecological segregation between ecologically similar species. For a set of commonly observed species, significant differences in their use of structural features, substrates and heights were registered between riparian and non-riparian habitats. The availability and dynamics of resources in riparian and non-riparian habitats were examined to determine if there is differential availability of particular resources, or in their temporal availability, throughout the annual cycle. Riparian zones supported more abundant and temporally reliable eucalypt flowering (i.e. nectar) than non-riparian habitats throughout the annual cycle. Riparian zones also supported an extensive loose bark resource (an important microhabitat for invertebrates) including more peeling bark and hanging bark throughout the year than at non-riparian sites. The productivity of eucalypts differed between habitat types, being higher in riparian zones at most times for all eucalypts combined, and for some species (e.g. Narrow-leaved Peppermint Eucalyptus radiata). Non-riparian habitats provided an abundant nectar resource (i.e. shrub flowering) at particular periods in the annual cycle. Birds showed clear relationships with the availability of specific food (i.e. nectar) and foraging resources (i.e. loose bark). The demonstration of a greater abundance of resources and higher primary productivity in riparian zones is consistent with the hypothesis that these linear strips that occupy only a small proportion of the landscape have a disproportionately high value for birds. Riparian zones in continuous eucalypt forest provide high quality habitats that contribute to the diversity of habitats and resources available to birds in the forest mosaic, with positive benefits for the landscape-level species pool. Despite riparian and non-riparian habitat supporting distinct assemblages of birds, strong linkages are maintained along the riparian-upslope gradient. Clearly, the maintenance of diverse and sustainable assemblages of birds in forest landscapes depends on complementary management of both riparian and non-riparian vegetation.

Influence of land cover on water resources

The influence of land cover on water quality and quantity was examined using a multidisciplinary approach that integrated land use maps, historical databases, and statistical modelling. Systematic changes in the Glenelg Hopkins landscape were identified, in addition to a relationship between greater proportions of vegetation and better water quality.

Entrepreneurship education at university : the plus-zone challenge

The paper discusses the contrast between what is being done and what ought to be done about entrepreneurship education at university level. Research from the Global Entrepreneurship Monitor program demonstrates that entrepreneurship education is an issue of worldwide economic and social significance. It has major policy implications for every nation. The paper briefly discusses the network of entrepreneurship education and experiential learning of which the university is only one component – and not necessarily the most important. The strategic and organizational context of the movement towards more entrepreneurial universities is distinguished from the purely content issue of curriculum designed for aspiring entrepreneurial practitioners. An overview of actual curricula, worldwide, is contrasted with the normative entrepreneurship education framework posited by McMullan and Long (1987). Following consideration of the problems involved in measuring the success of entrepreneurship education programs, a broad, generic template for integrated program development is presented and compared with the approach usually employed in most MBA programs at university business schools. The hierarchical, functionalist approach, symbolized by a pyramid, is contrasted with a more fluid, organic and boundary-crossing approach, symbolized by a wheel. Its central hub is a ‘plus zone’ where lies the deepest challenge for development of entrepreneurship education in a university context.

Birth of a biome : insights into the assembly and maintenance of the Australian arid zone biota

The integration of phylogenetics, phylogeography and palaeoenvironmental studies is providing major insights into the historical forces that have shaped the Earth’s biomes. Yet our present view is biased towards arctic and temperate/tropical forest regions, with very little focus on the extensive arid regions of the planet. The Australian arid zone is one of the largest desert landform systems in the world, with a unique, diverse and relatively well-studied biota. With foci on palaeoenvironmental and molecular data, we here review what is known about the assembly and maintenance of this biome in the context of its physical history, and in comparison with other mesic biomes. Aridification of Australia began in the Mid-Miocene, around 15 million years, but fully arid landforms in central Australia appeared much later, around 1–4 million years. Dated molecular phylogenies of diverse taxa show the deepest divergences of arid-adapted taxa from the Mid-Miocene, consistent with the onset of desiccation. There is evidence of arid-adapted taxa evolving from mesicadapted ancestors, and also of speciation within the arid zone. There is no evidence for an increase in speciation rate during the Pleistocene, and most arid-zone species lineages date to the Pliocene or earlier. The last 0.8 million years have seen major fluctuations of the arid zone, with large areas covered by mobile sand dunes during glacial maxima. Some large, vagile taxa show patterns of recent expansion and migration throughout the arid zone, in parallel with the ice sheet-imposed range shifts in Northern Hemisphere taxa. Yet other taxa show high lineage diversity and strong phylogeographical structure, indicating persistence in multiple localised refugia over several glacial maxima. Similar to the Northern Hemisphere, Pleistocene range shifts have produced suture zones, creating the opportunity for diversification and speciation through hybridisation, polyploidy and parthenogenesis. This review highlights the opportunities that development of arid conditions provides for rapid and diverse evolutionary radiations, and re-enforces the emerging view that Pleistocene environmental change can have diverse impacts on genetic structure and diversity in different biomes. There is a clear need for more detailed and targeted phylogeographical studies of Australia’s arid biota and we suggest a framework and a set of a priori hypotheses by which to proceed.

Stakeholder involvement and interplay in coastal zone management and marine protected area planning

Most of Australia’s coastline and marine waters are crown ‘land’ and can be accessed by the public. As a result, many different users and stakeholder groups have an interest in coastal and marine planning and management decisions. As a way of analysing stakeholder involvement and interplay in coastal zone management and marine protected area (MPA) development in Australia, three case studies are presented to dissect the issues and explore common themes. The three themes are 1) Stakeholder involvement in implementing the oceans policy, 2) Stakeholder involvement in marine protected area network identification and 3) Stakeholder involvement in coastal land issues.

Australian universities, government research and the application of climate change knowledge in Australian coastal zone management

One of the key issues in Australia for sustainable management of the coastal zone is that the science of climate change has not been widely used by decision-makers to inform coastal governance. There exist opportunities to enhance the dialogue between knowledge-makers and decision-makers, and universities have a key role to play in researching and fostering better linkages. At the heart of these linkages lies the principle of more informed engagement between historically disparate groups. In Australia, the new ‘Flagship’ research programme, funded by the Commonwealth Scientific and Industrial Research Organization (CSIRO), emphasizes their partnering with universities in a more systematic and collaborative manner than previously achieved in such research projects. In order to address sustainability in general and coastal adaptation to climate change in particular, interdisciplinary learning needs to occur between the social and natural sciences; also, transdisciplinary understanding of that interaction needs to be fully developed. New methods of communicative engagement such as computer visualizations and animations, together with deliberative techniques, can help policy-makers and planners reach a better understanding of the significance of the science of climate change impacts on the coast. Deeper engagement across historically disparate groups can lead to the development of epistemological and methodological synergies between social and natural scientists, adaptive learning, reflexive governance, and greater analytical and deliberative understanding among scientists, policymakers and the wider public. This understanding can lead in turn to enhance coastal governance for climate adaptation on the coast.

Implementing climate change policies consistent with integrated coastal zone management : a case study of Victoria, Australia

Whilst the proliferation of publications on climate change science is remarkable and makes the updating of responses to impacts of climate change on coastal environments daunting, the area of policy responses is even more confusing and complex. This is because policy responses do not need to consider the science of climate change alone but also have to weigh up the social and economic implications of the impact of climate change on coastal communities. In a federated nation such as Australia this has the added complication of three tiers of Government (Federal, State and local) having to interact in order to co-ordinate any policy responses. These complications should be aided by the internationally accepted concept of Integrated Coastal Zone Management (ICZM) which has been prevalent in Australian coastal planning and management for several decades. This paper uses the State of Victoria, Australia as a case study of how Governments are responding to these challenges through using the principles of ICZM. The paper will review recent inquires and investigations in Australia and canvas the policy responses to these reviews, concentrating on the State of Victoria. The paper analyses how consistent these evolving policy responses are with ICZM and suggests lessons for other jurisdictions arising from the Victorian experience.
