Comparing the conditions for small business and entrepreneurship in Sweden and Australia: Lessons for the European Charter for Small Enterprises

A growing body of literature is concerned with explaining cross-national performance of small business and entrepreneurs in advanced economies. This literature has considered a range of policy and institutional variables which create an environment supportive of small firms and entrepreneurial activities including macroeconomic variables such as taxation, labour market regulation, social security and income policy; regulatory factors such as establishment legislation, bankruptcy policy, administrative burdens, compliance costs, deregulation and competition policy; and cultural factors such as social and cultural norms that support entrepreneurship. However, this literature has not always distinguished between the policy environment of small firms operating in different industry sectors. The purpose of this paper is to examine the institutional and policy environment of small firms in knowledge intensive sectors. The characteristics of the business environment of particular relevance to knowledge intensive firms are somewhat different from the conditions for entrepreneurship and small business success more generally. This paper compares the science, technology and industry infrastructure of Australia, Denmark, Sweden with other OECD countries. The purpose of the paper is to identify cross-national differences in the business environment of small knowledge intensive firms. The paper seeks to explore whether particular institutional environments appear to be more supportive of small firms in knowledge intensive sectors.

The social identity perspective - Intergroup relations, self-conception, and small groups

The historical development, metatheoretical background, and current state of the social identity perspective in social psychology are described. Although originally, an analysis mainly of intergroup relations between large-scale social categories, and more recently an analysis with a strong social cognitive emphasis, this article shows that the social identity perspective is intended to be a general analysis of group membership and group processes. It focuses on the generative relationship between collective self-conception and group phenomena. To demonstrate the relevance of the social identity perspective to small groups, the article describes social identity research in a number of areas: differentiation within groups; leadership; deviance; group decision making; organizations; computer mediated communication; mobilization, collective action, and social loafing; and group culture. These art the areas in which most work has been done and which arc therefore best placed for further developments in the near future.

The challenges of abundance: epithelial junctions and small GTPase signalling

Small GTPases of the Ras superfamily play critical roles in epithelial biogenesis. Many key morphogenetic functions occur when small GTPases act at epithelial junctions, where they mediate an increasingly complex interplay between cell-cell adhesion molecules and fundamental cellular processes, such as cytoskeletal activity, polarity and trafficking. Important recent advances in this field include the role of additional members of the Ras superfamily in cell-cell contact stability and the capacity for polarity determinants to regulate small GTPase signalling. Interestingly, small GTPases may participate in the cross-talk between different adhesive receptors: in tissues classical cadherins can selectively regulate other junctions through cell signalling rather than through a global influence on cell-cell cohesion.

Analytical solutions of linear finite- and small-strain one-dimensional consolidation

Analytical solutions are presented for linear finite-strain one-dimensional consolidation of initially unconsolidated soil layers with surcharge loading for both one- and two-way drainage. These solutions complement earlier solutions for initially unconsolidated soil layers without surcharge and initially normally consolidated soil layers with surcharge. Small-strain solutions for the consolidation of initially unconsolidated soil layers with surcharge loading are also presented, and the relationship between the earlier solutions for initially unconsolidated soil without surcharge and the corresponding small-strain solutions, which was not addressed in the earlier work, is clarified. The new solutions for initially unconsolidated soil with surcharge loading can be applied to the analysis of low stress consolidation tests and to the partial validation of numerical solutions of non-linear finite-strain consolidation. They also clarify a formerly perplexing aspect of finite-strain solution charts first noted in numerical solutions. Copyright (C) 2004 John Wiley Sons, Ltd.

Brain maps, great and small: lessons from comparative studies of primate visual cortical organization

In this paper, we review evidence from comparative studies of primate cortical organization, highlighting recent findings and hypotheses that may help us to understand the rules governing evolutionary changes of the cortical map and the process of formation of areas during development. We argue that clear unequivocal views of cortical areas and their homologies are more likely to emerge for 'core' fields, including the primary sensory areas, which are specified early in development by precise molecular identification steps. In primates, the middle temporal area is probably one of these primordial cortical fields. Areas that form at progressively later stages of development correspond to progressively more recent evolutionary events, their development being less firmly anchored in molecular specification. The certainty with which areal boundaries can be delimited, and likely homologies can be assigned, becomes increasingly blurred in parallel with this evolutionary/developmental sequence. For example, while current concepts for the definition of cortical areas have been vindicated in allowing a clarification of the organization of the New World monkey 'third tier' visual cortex (the third and dorsomedial areas, V3 and DM), our analyses suggest that more flexible mapping criteria may be needed to unravel the organization of higher-order visual association and polysensory areas.

Molecular motors-based micro- and nano-biocomputation devices

Protein molecular motors, which are natural nano-machines that convert the chemical energy into mechanical work for cellular motion, muscle contraction and cell division, have been integrated in the last decade in primitive nanodevices based on the motility of nano-biological objects in micro- and nano-fabricated structures. However, the motility of microorganisms powered by molecular motors has not been similarly exploited. Moreover, among the proposed devices based on molecular motors, i.e., nanosensors, nano-mechanical devices and nano-imaging devices, biocomputation devices are conspicuously missing. The present contribution discusses, based on the present state of the art nano- and micro-fabrication, the comparative advantages and disadvantages of using nano- and micro-biological objects in future computation devices.

Towards an understanding of creativity and innovation within professional services and marketing

Greatly increased competition in the professional services and marketing sectors has reinforced the need for firms to develop an organisational culture that facilitates adaptation to changing conditions and competitive threats. More generally, competitive changes within business environments require new and creative ways of organising and managing firms. In order for marketing practitioners to be ahead of competitors in identifying and meeting customer needs, creative thought is essential. An organisational culture that supports creativity and facilitates the adoption of innovative practices, products and services, improves a firm’s ability to remain competitive within an uncertain environment. This paper presents a conceptual model of an organisational culture supporting creativity and innovation. The model posits relationships between creativity and innovation and organisational performance. The main contribution of the paper is to build a foundation for future research directed primarily towards exploring the relationships in the theoretical model of interest. Implications for marketing practitioners are also considered.

Explaining variations in the knowledge economy in three small wealthy countries

At a broad level, it has been shown that different institutional contexts, policy regimes and business systems affect the kinds of activities in which a nation specialises. This paper is concerned with the way in which different national business systems affect the nature of participation of a nation in the knowledge economy. The paper seeks to explain cross-national variations in the knowledge economy in the Australia, Denmark and Sweden with reference to dominant characteristics of the business system. Although Australia, Denmark and Sweden are all small wealthy countries, they each have quite distinctive business systems. Australia has been regarded as a variant of the competitive business system and has generally been described as an entrepreneurial economy with a large small firm population. In contrast Sweden has a coordinated business system that has favoured large industrial firms. The Danish variant of the coordinated model, with its well-developed vocational training system, is distinguishable by its large population of networked small and medium size enterprises. The three countries also differ significantly on two dimensions of participation in the knowledge economy. First, there is cross-national variation in patterns of specialisation in knowledge intensive industries and services. Second, the institutional infrastructure of the knowledge economy (or the existing stock of knowledge and competence in the economy, the potential for generation and diffusion a new knowledge and the capacity for commercialisation of new ideas) differs across the three countries. This paper seeks to explain variations in these two dimensions of the knowledge economy with reference to characteristics of the business system in the three countries.
