The Transition to Post-industrial BMI Values among US Children
Marco Sunder, Ariane Breitfelder, John Komlos
American Journal of Human Biology,
2009
Abstract
The trend in the BMI values of US children has not been estimated very convincingly because of the absence of longitudinal data. Our objective is to estimate time series of BMI values by birth cohorts instead of measurement years. We use five regression models to estimate the BMI trends of non-Hispanic US-born black and white children and adolescents ages 2-19 between 1941 and 2004. The increase in BMIZ values during the period considered was 1.3 (95% CI: 1.16; 1.44) among black girls, 0.8 for black boys, 0.7 for white boys, and 0.6 for white girls. This translates into an increase in BMI values of some 5.6, 3.3, 2.4, and 1.5 units, respectively. While the increase in BMI values started among the birth cohorts of the 1940s among black girls, the rate of increase tended to accelerate among all four ethnic/gender groups born in the mid-1950s to early-1960s. Some regional evidence leads to the conjecture that the spread of automobiles and radios affected the BMI values of boys already in the interwar period. We suppose that the changes in lifestyle associated with the labor saving technological developments of the 20th century are associated with the weight gains observed. The increased popularity of television viewing was most prominently associated with the contemporaneous acceleration in BMI gain. Am. J. Hum. Biol., 2009. © 2008 Wiley-Liss, Inc.

New Growth and Poverty Alleviation Strategies for Africa – Institutional and Local Perspectives. African Development Perspectives Yearbook, Vol. 14
Tobias Knedlik, Karl Wohlmuth, Philippe Burger, Achim Gutowski, Mareike Meyn, T. (eds) Urban, Afeikhena Jerome
,
2009
Abstract
The Volume XIV analyses the “New Growth and Poverty Alleviation Strategies for Africa“. Institutional issues and perspectives in designing new growth and poverty alleviation strategies are considered in various case studies (Cote d'Ivoire, Nigeria, Botswana and Tanzania). Other studies deal with institutional problems of resource-rich countries after conflict (Sudan) and with the institutions to enhance environmental protection parallel to economic growth and poverty reduction (Niger). Further studies deal with institutions to bridge the gap between formal and informal entrepreneurial sectors in Kenya and Tanzania. Local issues and perspectives for designing new growth and poverty alleviation strategies are considered in case studies on rural-urban development gaps in Tanzania and on microfinance as an instrument for new growth and poverty alleviation strategies (Tanzania and Eritrea). A study on small farmers in Ghana provides information on the role they can play in value chains. Two studies on Nigeria highlight the local and the sub-regional health and poverty alleviation programmes and the relation to growth. Book reviews and book notes on the theme are part of the volume. This volume builds the foundation for a comprehensive strategy of policy reforms in Africa so as to integrate new growth and poverty alleviation strategies. Complementary to Volume XIV is Volume XIII on “New Growth and Poverty Alleviation Strategies for Africa - Interational and Regional Perspectives“. Both volumes are of importance for all those who work in African countries as officials, executives, managers, researchers, and policy-makers, but also for all those who actively support Africa's development concerns at the international, regional, country, local, and project levels. They will experience this Volume XIV and also the complementary Volume XIII as indispensable sources of insight, reference, and inspiration.

Auswirkungen eines weltweiten Zinsanstiegs auf die Konjunkturentwicklung
Oliver Holtemöller, Andrej Drygalla, Axel Lindner
IWH Online,
No. 5,
2014
Abstract
Im Frühjahr und Sommer 2013 ließ die Aussicht auf eine allmähliche Abkehr der US-Notenbank von ihrem sehr expansiven Kurs die langfristigen US-Zinsen um über einen Prozentpunkt steigen. Damit wurde die Anlage von Kapital in anderen Wirtschaftsräumen weniger attraktiv. Finanzinvestoren zogen Gelder aus Schwellenländern ab, und die Währungen Brasiliens, Indiens, Indonesiens, Südafrikas und der Türkei verloren deutlich an Wert. Für diese Länder deuten gegenwärtig Frühindikatoren auf eine Abschwächung der gesamtwirtschaftlichen Aktivität hin. Zwar wird mittlerweile wieder erwartet, dass die Geldpolitik in den USA noch längere Zeit expansiv bleiben wird. Dennoch werden die zurzeit historisch niedrigen Zinsen in den fortgeschrittenen Volkswirtschaften über kurz oder lang wieder steigen. Es stellt sich deshalb die Frage, welche Effekte auf die Weltkonjunktur von einem deutlichen Zinsanstieg in den fortgeschrittenen Volkswirtschaften zu erwarten sind. Die Turbulenzen vom Sommer dieses Jahres zeigen, dass es auch dann zu einem erwartungsgetriebenen Anstieg der langfristigen Zinsen kommen kann, wenn die durch die Zentralbanken bestimmten kurzfristigen Zinsen noch unverändert niedrig sind. Ein solcher Zinsanstieg kann auf Änderungen der Langfrist-Erwartungen hinsichtlich Wachstum oder Inflation zurückgehen, er kann vorübergehend oder auch von Dauer sein.

The Structure and Evolution of Inter-sectoral Technological Complementarity in R&D in Germany from 1990 to 2011
T. Broekel, Matthias Brachert
Journal of Evolutionary Economics,
No. 4,
2015
Abstract
Technological complementarity is argued to be a crucial element for effective R&D collaboration. The real structure is, however, still largely unknown. Based on the argument that organizations’ knowledge resources must fit for enabling collective learning and innovation, we use the co-occurrence of firms in collaborative R&D projects in Germany to assess inter-sectoral technological complementarity between 129 sectors. The results are mapped as complementarity space for the Germany economy. The space and its dynamics from 1990 to 2011 are analyzed by means of social network analysis. The results illustrate sectors being complements both from a dyadic and portfolio/network perspective. This latter is important, as complementarities may only become fully effective when integrated in a complete set of different knowledge resources from multiple sectors. The dynamic perspective moreover reveals the shifting demand for knowledge resources among sectors at different time periods.

Universities, Innovation, Region: Knowledge Transfer in a Spatial Context
Tobias Henning, Michael Fritsch, Viktor Slavtchev, N. Steigenberger, Tobias Henning
Forschung aus der Hans-Böckler-Stiftung, Bd. 82,
2007
Abstract
Innovationen sind der Motor regionaler Entwicklung. Hochschulen werden zunehmend als wichtige Akteure in regionalen Innovationsprozessen angesehen. Dieses Buch untersucht die Bedeutung von Hochschulen für Innovationsaktivitäten und für eine regional orientierte Innovationspolitik am Beispiel von vier ostdeutschen Regionen. Im Mittelpunkt steht die Frage, wie das Wissen der Hochschulen in die private Wirtschaft gelangt. Dabei kommt im Rahmen verschiedener empirischer Erhebungen dem Wissenstransfer in Form der direkten Zusammenarbeit zwischen Hochschulen und privaten Unternehmen zentrale Bedeutung zu. Die Autoren untersuchen die Motive für und die spezifischen Probleme von solchen Kooperationen sowie die Frage, inwieweit hiermit positive Wirkungen für das regionale Umfeld der Hochschulen verbunden sind. Weitere Schwerpunkte der Analyse liegen bei der Bedeutung von Hochschulpatenten für den Innovationstransfer sowie den Möglichkeiten und Grenzen der Wirksamkeit von Patentverwertungsagenturen und Technologietransferstellen. Die Handlungsempfehlungen zur Intensivierung des Wissenstransfers richten sich sowohl an die Politik als auch an die Hochschulen selbst.

Industry Specialization, Diversity and the Efficiency of Regional Innovation Systems
Michael Fritsch, Viktor Slavtchev
Jena Economic Research Papers, Nr. 2007-018,
No. 18,
2007
Abstract
Innovation processes are characterized by a pronounced division of labor between actors. Two types of externality may arise from such interactions. On the one hand, a close location of actors affiliated to the same industry may stimulate innovation (MAR externalities). On the other hand, new ideas may be born by the exchange of heterogeneous and complementary knowledge between actors, which belong to different industries (Jacobs’ externalities). We test the impact of both MAR as well as Jacobs’ externalities on innovative performance at the regional level. The results suggest an inverted u-shaped relationship between regional specialization in certain industries and innovative performance. Further key determinants of the regional innovative performance are private sector R&D and university-industry collaboration.
