A critical review of entrepreneurial ecosystems research: towards a future research agenda

The entrepreneurial ecosystem (EE) literature has attracted much attention, especially in policy circles. However, the concept suffers from a number of shortcomings: (1) it lacks a clear analytical framework that makes explicit what is cause and what is effect in an EE; (2) while being a systemic concept, the EE has not yet fully exploited insights from network theory, and it is not always clear in what way the proposed elements are connected in an EE; (3) it remains a challenge what institutions (and at what spatial scale) impact on the structure and performance of EE; (4) studies have often focused on the EE in single regions or clusters, but lack a comparative and multi-scalar perspective and (5) the EE literature tends to provide a static framework taking a snapshot of EE without considering systematically their evolution over time. For each of these shortcomings, we make a number of suggestions to take up in future research on EE.     

A review of archaeological research on sami prehistory

Abstract

The English botanist and gardener John Tradescant the Elder's diary from a voyage to northern Russia in 1618 has lately attracted attention as a potential source on early Russian sea mammal hunting on the Svalbard archipelago. This article examines the usefulness of Tradescant's diary in this respect, but comes to a negative conclusion.     

Creative class politics: unions and the creative economy

This article examines how cultural workers participate in the construction and contestation of the creative economy at the policy level. An analysis of the role unions play in the film and television industry association FilmOntario demonstrates the paradox that the creative economy, as an economic development strategy, presents to the cultural workforce. FilmOntario has succeeded in attracting a high volume of work to the province through film and television tax credit advocacy. Although FilmOntario’s success in policy advocacy is deeply tied to union resources, the unions’ decision to work within creative economy discourses, and in association with employers, has prevented core issues related to the quality of work from being articulated as a function of policy design. The argument is that the discursive and associational choices unions, as the collective voice of the (creative) working class, make as policy actors have a significant impact on the degree to which cultural labour problems are understood as cultural policy problems.     

The prehistory of Island Southeast Asia: A multidisciplinary review of recent research

Island Southeast Asia extends across both the equatorial and the intermediate tropical zones of world climate, and it also spans a region of complex and geologically unstable land and sea relationships. The Sundaland region in the west and the isolated islands of Wallacea in the east both witnessed complex trajectories of human movement and evolution during the Pleistocene. The record of human evolution in Sundaland is still affected by uncertainties over phylogeny, dates, and archaeological correlations. Initial human settlement across Huxley's Line into Wallacea cannot at present be proven to be older than the Late Pleistocene. Stone tool industries dating to within the past 40,000 years are described, including new discoveries which indicate a surprising level of technological virtuosity. Human populations of the Late Pleistocene and Holocene are also considered in terms of skeletal and genetic data, particularly with respect to the rather controversial antecedents of the present, mainly Mongoloid, population. The article terminates its coverage at about 2000 B.C., within the period characterized by the expansion of speakers of Austronesian languages and by the expansion of agriculture into a porous and often-resistant network of hunter-gatherer societies. The archaeological and ethnographic records of the region bear witness to a continuous but dwindling existence of hunting and gathering right through to the present day. While the results of archaeology occupy a central position in the reconstruction of Southeast Asian prehistory, a proper understanding can be achieved only if a multidisciplinary standpoint is adopted.     

Cross-border mergers/acquisitions: a review and research agenda

Cross-border mergers/acquisitions account for the bulk of contemporaryforeign direct investment. Their significance, which is reinforcingthe position of transnational corporations as the dominant institutionalforce in the global economy, is related to the nexus of processesimplicated in international economic restructuring. Cross-bordermergers/acquisitions are, therefore, important influences uponthe evolution of the space economy, but this perspective onmerger/acquisition activity has been neglected in academic research.This review makes connections between disparate literaturesto identify potential lines of enquiry and attempts to situatethese lines of enquiry within current research agendas in economicgeography. On a basic level, mergers/acquisitions create newcorporate geographies which represent valid objects of researchin the geography of enterprise tradition. However, these corporategeographies are set within the institutional context of social,economic, and political relations. Many of the most interestingresearch questions derive from these contextual relations whichare addressed with reference to issues of embeddedness at variousgeographical scales and also by linking these issues to aspectsof employment and territorial development.     

The neolithic and early bronze age of the Lake Baikal Region: A review of recent research

Rich settlement and burial evidence from the Baikal/Angara region in Central Siberia provides one of the most promising opportunities in the global boreal forest for studying Holocene foragers. The Neolithic and Early Bronze Age prehistory of the region is known to western scholars only through a few English translations of the works of A. P. Okladnikov. Since the publication of Okladnikov's model, the region has witnessed large-scale archaeological fieldwork that has produced abundant quantities of new evidence. Moreover, the model has been partly invalidated by extensive radiocarbon dating. Research advances over the last couple of decades have augmented the area's previous reputation but have also revealed the need for new theoretical perspectives and modern analytical techniques.

Functional analysis of prehistoric flint tools by high-power microscopy: A review of West European research

The present paper is a review of the functional analysis of prehistoric flint tool edges by means of high-power microscopy. The article, which focuses exclusively on West European research, discusses a series of methodological issues and problems related to the development and distinctiveness of the so-called wear polishes, produced by the various materials with which prehistoric stone tools came in contact. A selection of functional observations on tool use from the Upper Paleolithic, the Mesolithic, and the Neolithic periods is presented. The archaeological part of the review is concerned with two trends in functional analysis, namely, (1) controlled site-specific studies with different levels of foci and (2) thematic studies of particular tool types, e.g., endscrapers, burins, and unmodified débitage. Finally, problems concerning the interpretation of hafting and of multiple tool use are discussed.     

Archaeological research in Lesotho: a review of 120 years

Archaeological research in Lesotho over the last 120 years is reviewed. Particular emphasis is given to P. Carter's excavation and survey project in eastern Lesotho and to contract archaeology projects in other parts of the country. Current research and projects involving the study of rock art are also considered. The archaeological potential of Lesotho for addressing a number of themes is discussed. These themes include the reconstruction of prehistoric seasonal mobility patterns, hunter-gatherer adaptations at the Last Glacial Maximum and relations between hunter-gatherer and farming populations. Lesotho's geographical situation lends itself to examining these questions across two distinct ecological gradients, but the richness of its rock art also demonstrates its potential for investigating Stone Age social relations. The importance of developing a more effective national archaeological infrastructure is stressed.

Résumé Les recherches archéologiques des 120 dernières années sont passées en revue. L'accent est mis tout particuliérement sur les fouilles et le survey conduits dans l'est du Lesotho par P. Carter ainsi que sur les contrats de recherches archéologiques dans d'autres régions du pays. Les recherches en cours et les projets comprennant l'étude de l'art rupestre sont aussi passés en revue.Le potentiel archéologique du Lesotho pour l'étude d'un certain nombre de thèmes est discuté. Ces thèmes comprennent la reconstruction des mouvements saisoniers et des adaptations des chasseurs/cueilleurs durant le dernier maximum glaciaire ainsi que les relations entre les chasseurs/cueilleurs et les populations fermières. Le Lesotho, de par sa situation géographique, permet d'examiner ces questions au travers de deux niveaux écologiques distincts, cependant que la richesse de son art rupestre démontre son potentiel pour étudier les relations sociales durant l'Age de la Pierre. L'importance du développement d'une infrastructure archéologique nationale plus poussée est soulignée.

     

Police unions and use-of-force reforms in American cities

Following the murder of George Floyd, there was widespread debate about the policies that govern the use of force by police, but municipal leaders suggested that police unions kept many of the proposed changes from being adopted. Although there is anecdotal and scholarly evidence that unions frequently oppose policing reform, the limited literature in this area actually offers somewhat mixed conclusions about the relationship between union strength and the success of previous reform efforts. In this study, we draw on Halpin's theory of interest groups as politically adaptive organizations to develop expectations about the behavior of police unions in police governance subsystems. We hypothesize that union attempts to influence policy will correlate positively with reform adoption when the political environment is conducive to victory on that front or makes the cost of opposition too high and negatively when the opposite conditions hold. Analyses of the impact of union campaign contributions on the adoption of use-of-force policies in the 100 largest U.S. cities demonstrate that the nature and direction of union influence are moderated by the political climate of the jurisdiction in which they operate.     

A review of (almost) 20 years of regional innovation systems research

ABSTRACT

The literature on regional innovation systems (RISs) has grown impressively in the last two decades. The objective of this study is to provide a comprehensive assessment of all RIS articles published in scholarly journals between 1998 and 2015. It aims to inform researchers of the empirical results obtained so far and highlight areas that need further work. This review describes how the RIS field has developed, charts the current body of RIS research and discusses recommendations for moving the RIS field forward.     

Military geography: A review

Through sixty years of chequered fortune the Magazine showed the impact of current history, notably during the 1914‐18 war when a few authors, notably Newbigin, Chisholm and Mackinder, wrote fine articles on current international problems. From 1919 many studies of geography as a whole and of its various branches appeared, a number of them given as presidential addresses to Section E of the British Association. The tradition of publishing local research studies was maintained and developed from the 1930's, both for Scotland and for areas elsewhere.     

Obsidian sources and distribution systems in Island Southeast Asia: a review of previous research

This paper summarises research on obsidian findings across the region of Island Southeast Asia (ISEA), from the first reporting of obsidian on Sumatra as a result of cave excavations in the early 1900s through to the latest published discoveries in 2009. These results are the background for the first region-wide research project focussing on obsidian characterisation and its role in prehistoric inter-island exchange. It is commonly held that distribution of obsidian in ISEA was only localised and inter-island transportation limited. The review, however, suggests that this hypothesis derives from an incomplete knowledge of obsidian distribution in the region rather than typifying prehistoric social patterns. Obsidian sourcing has been carried out only intermittently in ISEA since the 1970s and has generally been focussed only at the single site level, thus explaining this very partial understanding.
