Policy Bubbles

We develop the concept of a policy bubble to capture the notion of long‐term overinvestment in a policy. In sketching the relation of policy bubbles to economic bubbles, we describe how these two concepts have similar origins but different trajectories because they are filtered by different institutions. We examine in some detail three likely instances of ongoing policy bubbles: crime policy, school reform (charter schools and private education vouchers), and the contracting and privatization of public services. We show how these cases differ from the housing bubble of 1997–2007, how they differ from each other, and the extent to which they can be considered policy bubbles. Last, we suggest this concept can help unify the policy process literature with the practice of policy evaluation and outline testable hypotheses for future research.     

The Importance of Attention Diversity and How to Measure It

Studies of political attention often focus on attention to a single issue, such as front‐page coverage of the economy. However, examining attention to a single issue without accounting for the agenda as a whole can lead to faulty assumptions. One solution is to consider the diversity of attention; that is, how narrowly or widely attention is distributed across items (e.g., issues on an agenda or, at a lower level, frames in an issue debate). Attention diversity is an important variable in its own right, offering insight into how agendas vary in their accessibility to policy problems and perspectives. Yet despite the importance of attention diversity, we lack a standard for how best to measure it. This paper focuses on the four most commonly used measures: the inverse Herfindahl Index, Shannon's H, and their normalized versions. We discuss the purposes of these measures and compare them through simulations and using three real‐world datasets. We conclude that both Shannon's H and its normalized form are better measures, minimizing the danger of spurious findings that could result from the less sensitive Herfindahl measures. The choice between the Shannon's H measures should be made based on whether variance in the total number of possible items (e.g., issues) is meaningful.     

Recent research into oldowan hominin activities at Kanjera South, Western Kenya

This paper presents the initial results of excavations at Kanjera South, located on the Homa Peninsula in Western Kenya. Since 1995, our exploration of this locality has yielded a combination of artefacts and well preserved faunal remains in a sedimentary context that also allows for environmental reconstruction. Here we examine the history of exploration of Kanjera and its significance in the development of palaeoanthropological research in East Africa. We also summarise our findings from the recently discovered Oldowan site. Taphonomic analyses suggest that the archaeological layers were formed at least partially by hominin activity. Artefacts made from a wide variety of raw materials are abundant, as are animal bones. Results of our first analyses confirm that Oldowan hominins had considerable behavioural flexibility and occupied a range of habitats.Cet article présente des résultats préliminaires de nos fouilles au site de Kanjera South, situé sur la péninsule de Homa au Kenya occidental. Depuis 1995 nos explorations à cette localité ont produit une combinaison des outils lithiques et des restes fossils dans un bon état de conservation venant d’un contexte sédimentaire qui permet également les reconstitutions paleoenvironnementaux. Ici nous examinons l’histoire de l’exploration de Kanjera et de son importance dans le développement de la recherche paleoanthropologique en Afrique de l’Est. Nous récapitulons également nos résultats du gisement récemment découvert d’Oldowan. L’étude taphonomique suggère que les couches archéologiques ont été formées au moins partiellement par l’activité des hominins. Les objets fabriqués faits à partir d’une grande variété de matières lithiques sont abondants, de même que les os animaux. Les résultats de nos premières analyses confirment que les hominins d’Oldowan ont eu une flexibilité de comportement considérable et ont occupé une gamme d’habitats différents.     

Wirtschaftsförderung und Immobilienwirtschaft

Abstrakt Immobilienwirtschaft als Partner der Stadtentwicklung? Zugegeben eine Sichtweise, die oftmals in der Ausbildung von Planern oder Geographen etwas zu kurz kommt. Dabei w?re es oft sinnvoll, bei der Planung auch die Sicht der Immobilienwirtschaft respektive der künftigen Nutzer zu berücksichtigen. Seit jeher haben sich St?dte auch und vor allem durch die Baut?tigkeit von Privaten entwickelt. Investitionen der Kommunen und des Staates beschr?nkten sich in der Regel auf technische und soziale Infrastruktureinrichtungen und das eine oder andere Renommierobjekt, wie beispielsweise Museen, Theater, Opern. In Zeiten knapper ?ffentlicher Kassen werden selbst dafür zunehmend private Investitionen ben?tigt. In dem sich aktuell versch?rfenden Wettbewerb der St?dte und Regionen sind Investoren, die zur baulichen und wirtschaftlichen Entwicklung beitragen, wichtiger denn je. Wie sich das Zusammenspiel von Immobilienwirtschaft und Wirtschaftsf?rderung in der Praxis darstellt, schildern die Autoren beispielhaft anhand ihrer Erfahrungen aus der kommunalen Wirtschaftsf?rderung.     

Regional innovation systems and the foundation of knowledge intensive business services. A comparative study in Bremen,Munich, and Stuttgart,Germany

Knowledge intensive business services (KIBS) are believed to be one of the main drivers of technological change, innovation, and economic progress. Although firm foundations play a crucial role among KIBS, entrepreneurship research has hardly ever investigated the sector. As firm founders in early stages of their firms' development mostly draw on regional resources, and as the provision of the services is an interactive process, “proximity” between the different actors of the particular territorial innovation and production system clearly matters. This contribution analyses the interrelationships between KIBS foundations and their respective innovation and production systems by performing qualitative and conceptual in-depth studies of three German metropolitan regions.     

Kommunikation und Veränderung—aktuelle Herausforderungen in der Kommunalberatung

Die Herausforderung und das Ziel eines jeden kommunalen Beratungsprojektes ist die konsensorientierte und zielführende Kommunikation von notwendigen Veränderungen. Nicht unterschiedliche Städte und Gemeinden mit ähnlichen Problemlagen stehen im Vordergrund der Bearbeitung, sondern das höchst individuelle Angebot alternativer Kommunikationsverfahren. Auch der Kommunalberater aus der Geographie überzeugt vor allem durch seine persönliche Ansprache und seine beruflichen Erfahrungen. Die Perspektiven in diesem weiten Berufsfeld sind grundsätzlich nicht schlecht, wenn Geographen es heute und zukünftig verstehen, ihre fachlichen Vorzüge entsprechend darzulegen. Dieser Artikel soll Mut machen für die Herausforderungen vor Ort und Perspektiven aufzeigen!     

‘Partner in his Calamities’: Pastors' Wives,Married Nuns and the Experience of Clerical Marriage in the Early German Reformation

This essay examines what factors led the first clerical wives to marry former Catholic clergy and nuns to marry in the first decade of the Reformation in Germany and seeks to explain the difference that social class, geography and gender made in those decisions. In contrast to the later Reformation, when pastors married same or higher social status women, the majority of women who married former priests and monks during the 1520s were often lower or, in the case of nuns, significantly higher social status than their husbands. Women married clergy for a variety of reasons that were counterintuitive to typical marital strategies for economic security and social networking, since clergy had neither in the 1520s. While sharing a common experience, clerical wives' reasons for marriage to a pastor varied greatly depending on class, local decision about the Reformation and numerous personal factors. Using a variety of sources including letters, civic records, court testimony and published pamphlets, this article demonstrates that these women did exhibit a limited agency that ultimately helped shape larger social and political acceptance of clerical marriage.     

Oldowan behavior and raw material transport: perspectives from the Kanjera Formation

The archaeological record of Oldowan hominins represents a diverse behavioral system. It has been suggested that exploitation of lithic resources by Oldowan hominins was simplistic and represented mostly use of local sources of stone. Here we investigate the raw material selection and transport behaviors of Oldowan hominins reflected in the stone artifact assemblages from the Kanjera South Formation, South Rachuonyo District, Kenya. Using geochemical methods (ED-XRF) artifacts are linked to primary and secondary source outcrops throughout southwestern Kenya. These data show that hominins selected raw materials for transport at frequencies that are significantly different from their availability on ancient landscapes. Furthermore, a substantial proportion of the assemblage represents transport over relatively long distances (>10 km). Our study further suggests that in the early stages of stone tool use hominins used a wide variety of raw materials and selected these materials at some distance from their eventual discard locations. Early hominin behavior may have incorporated an understanding of raw material source distributions across a more extensive landscape than has been previously documented. This supports the growing perspective that Oldowan technology represents a more complex behavioral pattern than is usually associated with the beginnings of hominin tool use.
