How are small companies in the electronics sector managing?
Abstract This study explores the use of environmental management systems for initiating and controlling environmental improvements in the context of supply chain cooperation. It examines how environmental requirements are reaching smaller companies in the electronics supply chain, especially in the light of recent legal changes such as enforcement of the RoHS Directive. It is based on qualitative interviews with environmental and purchasing managers of 21 small and medium-sized companies. The results point out a lack of significant drivers for these companies to implement proactive measures when dealing with environmental issues, owing to limited customer pressure. RoHS and legal compliance are the only environmental customer criteria to be met, while ISO 14001 works as an optional supplier selection criterion. In consequence, companies are not focusing on environmental work within their supply chains, and the potential of influencing the environmental profile of suppliers by shaping their ISO 14001 is not used.

Functional Management Competence and Growth of Young Technology-Based Firms

CREATIVITY AND INNOVATION MANAGEMENT, Issue 3 2008
Sören Salomo
Acknowledging an increased research interest into the success factors for young technology-based firms in the last decade, the present study serves two main purposes. First, we aim at developing a comprehensive concept of functional management competence in young technology-based firms. Functional management competence covers the understanding of and proficiency in managing specific functional tasks (Katz, 1974). As we focus on young technology-based firms, it is suggested that marketing, financial and technology management tasks are at the core of functional management competence. Second, we aim at delineating and validating an appropriate measurement model for functional management competence. In order to test the model's nomological validity, we investigate the impact of functional management competence on firm growth. Therefore, building on established firm development approaches, we propose a phase model for the development of young technology-based firms. Our study builds upon data from 212 young technology-based firms in the field of microtechnology, nanotechnology, electronics, optics and lasers. We use formative measurement models to establish valid and reliable constructs and a path model based on partial least squares modelling to investigate the performance effects. The results suggest that functional management competences generally are significant drivers of firm development speed. In particular, technology and marketing management competences are shown to impact development speed. While technology management competence is positively driving development speed, the marketing management competence impact on speed is mediated by competitive advantage of the new products developed by young technology-based firms. Financial management competence has no significant link to firm development speed. [source]


RECENT TRENDS IN AUSTRALIAN BANKING

ECONOMIC PAPERS: A JOURNAL OF APPLIED ECONOMICS AND POLICY, Issue S1 2006
KEITH HALL
This paper discusses the performance of Australian banks over the past decade, focusing on the forces that have shaped bank strategies and outcomes. The robust Australian economy and associated demand for credit, particularly from the household sector, have been significant drivers of bank success. Intensifying competition in lending and deposits has also played a role, manifesting itself largely as price pressure, but also spurring product innovation and the easing of lending standards. While the combination of these forces has allowed bank balance sheets to grow rapidly, the sector has remained well capitalised and has low levels of non-performing assets. [source]


Persistent effects of a discrete warming event on a polar desert ecosystem

GLOBAL CHANGE BIOLOGY, Issue 10 2008
J. E. BARRETT
Abstract A discrete warming event (December 21, 2001,January 12, 2002) in the McMurdo Dry Valleys, Antarctica, enhanced glacier melt, stream flow, and melting of permafrost. Effects of this warming included a rapid rise in lake levels and widespread increases in soil water availability resulting from melting of subsurface ice. These increases in liquid water offset hydrologic responses to a cooling trend experienced over the previous decade and altered ecosystem properties in both aquatic and terrestrial ecosystems. Here, we present hydrological and meteorological data from the McMurdo Dry Valleys Long Term Ecological Research project to examine the influence of a discrete climate event (warming of >2 °C) on terrestrial environments and soil biotic communities. Increases in soil moisture following this event stimulated populations of a subordinate soil invertebrate species (Eudorylaimus antarcticus, Nematoda). The pulse of melt-water had significant influences on Taylor Valley ecosystems that persisted for several years, and illustrates that the importance of discrete climate events, long recognized in hot deserts, are also significant drivers of soil and aquatic ecosystems in polar deserts. Thus, predictions of Antarctic ecosystem responses to climate change which focus on linear temperature trends may miss the potentially significant influence of infrequent climate events on hydrology and linked ecological processes.

Abiotic and biotic drivers of seedling survival in a hurricane-impacted tropical forest

JOURNAL OF ECOLOGY, Issue 6 2009
Liza S. Comita
Summary 1. ,Many forests experience periodic, large-scale disturbances, such as hurricanes and cyclones, which open the forest canopy, causing dramatic changes in understorey light conditions and seedling densities. Thus, in hurricane-impacted forests, large variations in abiotic and biotic conditions likely shape seedling dynamics, which in turn will contribute to patterns of forest recovery. 2. ,We monitored 13 836 seedlings of 82 tree and shrub species over 10 years following Hurricane Georges in 1998 in a subtropical, montane forest in Puerto Rico. We quantified changes in the biotic and abiotic environment of the understorey and linked seedling dynamics to changes in canopy openness and seedling density, and to spatial variation in soil type, topography and tree density. 3. ,Canopy openness was highest when first measured after Hurricane Georges and dropped significantly within c. 3 years, while seedling densities remained high for c. 5 years post-hurricane. When all species and census intervals were analysed together, generalized linear mixed effects models revealed that canopy openness, seedling and adult tree densities were significant drivers of seedling survival. 4. ,The relative importance of abiotic and biotic factors changed over time. Separate analyses for each census interval revealed that canopy openness was a significant predictor of survival only for the first census interval, with lower survival at the highest levels of canopy openness. The effect of conspecific seedling density was significant in all intervals except the first, and soil type only in the final census interval. 5. ,When grouping species into life-history guilds based on adult tree susceptibility to hurricane damage, we found clear differences among guilds in the effects of biotic and abiotic factors on seedling survival. Seedlings of hurricane-susceptible and intermediate guilds were more strongly influenced by canopy openness, while seedlings of the hurricane-resistant group were less affected by conspecific seedling density. Individual species-level analyses for 12 common species, however, showed considerable variation among species within guilds. 6. ,Synthesis. Our results suggest that hurricanes shape species composition by altering understorey conditions that differentially influence the success of seedlings. Thus, predicted increases in the intensity and frequency of hurricanes in the Caribbean will likely alter seedling dynamics and ultimately the species composition in hurricane-impacted forests.

The influence of multi-scale environmental variables on the distribution of terricolous lichens in a fog desert

JOURNAL OF VEGETATION SCIENCE, Issue 6 2006
Jennifer S. Lalley
Abstract Question: How do environmental variables in a hyper-arid fog desert influence the distribution patterns of terricolous lichens on both macro- and micro-scales? Location: Namib Desert, Namibia. Methods: Sites with varying lichen species cover were sampled for environmental variables on a macro-scale (elevation, slope degree, aspect, proximity to river channels, and fog deposition) and on a micro-scale (soil structure and chemistry). Macro-scale and micro-scale variables were analysed separately for associations with lichen species cover using constrained ordination (DCCA) and unconstrained ordination (DCA). Explanatory variables that dominated the first two axes of the constrained ordinations were tested against a lichen cover gradient. Results: Elevation and proximity to river channels were the most significant drivers of lichen species cover in the macro-scale DCCA, but results of the DCA suggest that a considerable percentage of variation in lichen species cover is unexplained by these variables. On a micro-scale, sediment particle size explained a majority of lichen community variations, followed by soil pH. When both macro and micro-scale variables were tested along a lichen cover gradient, soil pH was the only variable to show a significant relationship to lichen cover. Conclusion: The findings suggest that landscape variables contribute to variations in lichen species cover, but that stronger links occur between lichen growth and small-scale variations in soil characteristics, supporting the need for multi-scale approaches in the management of threatened biological soil crust communities and related ecosystem functions.
