Are the most productive regions necessarily the most successful? Local effects of productivity growth on employment and earnings

Economists typically celebrate productivity growth as the chief way to improve living standards. Productivity growth may reduce costs, improve quality, or lead to innovation and new products, but if demand is insufficiently elastic, productivity growth can lead to weakening of labor markets. We study county‐level effects of productivity growth and productivity levels on growth in employment, income, and earnings. The results suggest that productivity growth generally suppresses job growth but has boosting effects on earnings and, to a lesser degree, on per‐capita income, although there is considerable variation across geographies and specific outcomes.     

Using 3D scanning in the investigation of Upper Palaeolithic engravings: first results of a pilot study

This paper deals with the reinvestigation of selected engravings on slate plaquettes from the Late Upper Palaeolithic site of Gönnersdorf, Germany, by applying new 3D scanning methods for the first time. The aim of this method is to obtain further information about stylistic aspects of the depictions as well as to identify an inner chronology and interrelationship of the lines. In addition new options of 3D photography are tested as a further visual support of investigation and documentation. Previously analyses were subjective whereas the new interpretation uses impartial metric methods. In the future the more objective results will allow the comparison of engravings and their details, with the aim of discerning different artists as well as obtaining a better understanding of the art of former hunter- gatherer societies.     

High-throughput mass spectrometric analysis of 1400-year-old mycolic acids as biomarkers for ancient tuberculosis infection

The cell wall of mycobacteria includes an unusual outer membrane of extremely low permeability. This cell envelope consists of a characteristic cell wall skeleton, a mycoloyl arabinogalactan peptidoglycan complex, and related hydrophobic components that contribute to the cell surface properties. In this study 1400-year-old mycolic acids as unique tuberculosis biomarkers have been extracted and identified for the first time by using matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI TOF MS) and Fourier transform infrared spectroscopy (FT-IR). The data suggest that the MALDI TOF MS has potential as a rapid and reproducible technique for the detection and identification of ancient mycobacterial infections.     

Die „Vergleichende Kurortanalyse“ (VKA)

Kein touristisches Segment ist derzeit durch eine so massive Angebotsexpansion gekennzeichnet wie der Gesundheitstourismus. Allein in Deutschland versuchen sich heute mehr als 350 Heilbäder und Kurorte auf dem Markt der heiß umworbenen Selbstzahler zu positionieren. Aber auch außerhalb der Kurorte entwickelt sich das kur- und gesundheitstouristische Angebot dynamisch. Der nachfrageseitige Markt für gesundheitstouristische Dienstleistungen ist vielversprechend und hat eine weltweite Mobilisierung um den gesundheitsbewußten Touristen in Gang gesetzt. Um in diesem stark wachsenden Markt überhaupt wahrgenommen zu werden, müssen Anbieter mit einem klaren Profil erscheinen, vor allem Heilbäder und Kurorte, die ein eher traditionelles Image aufweisen. Zudem verlangen Investitionsvorhaben oder Wirtschaftsförderungen klare Entscheidungsgrundlagen der langfristigen Positionierung und Spezialisierung. Nicht zuletzt stellt sich die Frage, wie Heilbäder und Kurorte auf Destinations- bzw. Landesebene am Markt präsentiert werden müssen, um sich von anderen Bäderdestinationen zu unterscheiden. Für diese komplexe Aufgabenstellung hat das Europäische Tourismus Institut (ETI) ein abgestimmtes Erhebungs-, Bewertungs- und Analyseinstrument entwickelt, das konsequente Produkt- und Positionierungsentscheidungen für den einzelnen Kurort wie auch das Landes- oder Regionalmarketing ermöglicht. Die Vergleichende Kurortanalyse (VKA) berücksichtigt dabei sowohl die Bedürfnisse des Marktes als auch die spezifische Angebotsausstattung bzw. -attraktivität in den Orten.     

Immigrant Inclusion in the Safety Net: A Framework for Analysis and Effects on Educational Attainment

Across states, there is substantial variation in the degree to which immigrants and their children are offered public assistance. We present a theoretical framework for analyzing the effects of policy decisions about immigrant inclusion. We apply the framework to investigate the effect of the state safety net on educational attainment. We focus on the years following welfare reform in 1996, when states gained considerable autonomy over welfare policy, including decisions about the eligibility of immigrant residents. Leveraging state‐level data from before and after reform, we estimate a difference‐in‐difference model to identify the effect of variation in immigrant inclusivity on educational attainment. We find that when states broaden the inclusivity of the social safety net to immigrants, young Latinos are more likely to graduate from high school. This effect is present beyond the group of Latino residents who receive additional benefits, suggesting that policy decisions about immigrants spill over to broader communities and communicate broader messages about social inclusion to racial and ethnic groups. We find similar patterns among Asian youth, but not among black and non‐Hispanic white youth. We conclude that immigrant inclusion has consequences for the life prospects of the growing population of youth in high‐immigrant ethnic groups.     

Psychological components of middle paleolithic technology: The proceduralization of lithic core reduction

Exploring the evolution of human cognition has been as methodologically problematic as it has been a vital area of study over the last couple of decades. In particular, the integration of archaeology and psychology, while fundamental to many such studies, has suffered from a difficulty by many researchers to effectively link models from the cognitive sciences with the archaeological data ( [Wynn, 2009] and [Wynn and Coolidge, 2010] ). In the current study one psychological process, proceduralization is used to examine the technological strategies that underpin the sequential nature of lithic core reduction. This is done via the application of sequential lithic information analysis (SLIA), a method developed by the author for the concurrent study of qualitative and quantitative sequential information. In the present context SLIA helps elucidate both the micro- and macro-level dynamics that underlie the reduction of a sample of Middle Paleolithic refitted Levallois cores from the site of Taramsa-1, Upper Egypt. The results of this study provide an explanation for the variability recognised within the Levallois technology and also speak to the existence of certain aspects of modern cognition by ca. 70,000 years before present.     

Response to the Commentaries by Vessuri, Elzinga and Fouch��

The Matthew and Matilda Effects in science were coined in 1968 (Robert K. Merton) and in 1993 (Margaret W. Rossiter) respectively, as tools to analyse the reward systems of science. By proposing the African Eve Effect in science as a third effect, the original scope for analysis of these systems is broadened from the social structure of science to the anthropological dimension of science. Similarly, the ‘psychosocial processes’ that were considered as affecting the reward systems (Merton, Science 159:56–63, 1968) are extended to include discursive practices. The African Eve Effect refers to the scientific notion of the ‘African Eve’ (or mitochondrial (mtDNA) Eve), a concept put forward by scientists to designate the genetic mother of all modern humans. Three discursive conventions constitute the African Eve Effect and together shape patterns of the distribution of recognition for scientific work: projecting imaginative geographies of otherness onto the frontiers of science; collecting, transporting and enframing material and ideas according to a Western epistemological order; and ‘evolutionising’ nature and the human in science. The objective of this paper is to specify and illustrate an experimental tool for analysing the entanglement of the reward system in science with culturally fashioned imaginaries and agendas.
