What do muscle marker ruggedness scores actually tell us?

Musculoskeletal stress markers (MSM) have been used to reconstruct activity patterns and labour intensity of past populations. Age and size have been found to correlate with MSM, and these aspects should be considered in activity reconstructions. The aim of this study was to find out the nature and the effects of labour intensity, age and size on MSM. Study material were skeletons (N = 108) of individuals of known age, sex and occupation housed at the Natural History Museum, Finland. MSM were scored for Pectoralis major, Deltoid, Teres major and Biceps brachii. These scores were combined to reflect total activity of an individual. Geometric mean of humeral measurements was used as a size indicator and radial tuberosity size was used as a muscle size indicator. Factors explaining MSM were studied using ANCOVA. This included age, size, muscle size, sex, labour intensity, and their interactions. Age and muscle size were the most significant factors explaining MSM, where muscle attachment areas and MSM grow with advancing age. Muscle attachment areas and skeletal frame size were also found to correlate. Least squares regression parameter estimates were used to study the effects of labour intensity, sex and side on MSM. It was found that in early life scores are higher in heavy labour group, but there is less age‐related increase in these scores. This could mean that bone is unable to respond to heavy and continuous loading with surface structure. Therefore labour intensity cannot be reliably recorded in old individuals. Also age and size (as reflected in muscle attachment area) affect MSM and these aspects should be considered before making assumptions on labour intensity.

Knowledge Networks as a Regional Development Resource: A Network Analysis of the Interlinks between Scientific Institutions and Regional Firms in the Metropolitan region of Hanover,Germany

The debate on regional innovation potentials has concentrated in recent times upon the topic of regional knowledge networking. This article presents the findings of the first phase of a detailed network analysis of the cooperation relations between scientific institutions and firms in the “metropolitan region Hanover-Brunswick-Göttingen”. The research concentrated on the regional and supra-regional cooperation relations of approximately 500 science establishments of the region, including their interlinks with private sector firms. This analysis of a polycentric metropolitan region's knowledge networks in different fields of competence produced detailed information on the density of knowledge interlinking within the region, on the degree of connectivity between the region's scientific institutions and private sector firms, and on central network nodes within the regional innovation networks. The case study exemplifies the methodical approach of a regional network analysis and emphasizes the role of knowledge networks as a development resource which is of particular relevance to the region's innovation capacities.     

Abortion law reforms in Colombia and Nicaragua: issue networks and opportunity contexts

This article analyses two instances of abortion law reform in Latin America. In 2006, after a decades-long impasse, the highly controversial issue of abortion came to dominate the political agenda when Colombia liberalized its abortion law and Nicaragua adopted a total ban on abortion. The article analyses the central actors in the reform processes, their strategies and the opportunity contexts. Drawing on Htun's (2003) framework, it examines why these processes concluded with opposing legislative outcomes. The authors argue for the need to understand the state as a non-unitary site of politics and policy, and for judicial processes to be seen as a key variable in facilitating gender policy reforms in Latin America. In addition, they argue that ‘windows of opportunity’ such as the timing of elections can be critically important in legislative change processes.
