In this article I critically examine the theoretical and empirical relationship between world society, whereby global civil society is taken to be its physical or empirical counterpart, and the society of states. This relationship is typically portrayed as contradictory or confrontational, and I contend that this mainstream perspective is reliant on a superficial analysis of the relationship. If one examines the deeper dynamics, viewed in their contemporary international normative context, then one can identify the more constructive and permissive aspects of the relationship. Rather than being wholly incompatible I argue that world society and international society are mutually constitutive and mutually dependent regimes, whose relationship is more often marked by cooperation than by conflict. English School theory provides the conceptual framework for this analysis. The relationship between international and world society presents a core ontological tension within this theory, and again they tend to occupy polarised positions. A synthesis of four international theories - pluralist international society theory, solidarist international society theory, critical international theory, and the discourse of global civil society - informs the hypothesis that the relationship can be normatively and empirically reconciled. In order to empirically support this explanation I analyse two phenomena in world politics - transnational advocacy networks and humanitarian intervention - where there is an apparent tension between international and world society.

1. Protein utilisation and turnover were measured in male chickens sampled from a line selected for high breast yield and a randombred control line (lines QL and CL, experiment 1) and in male chickens sampled from lines selected for either high or low abdominal fatness (lines FL and LL, experiment 2). In each experiment, 18 birds per line were given iso-energetic (12.9 MJ ME/kg) diets containing either 120 or 220 g CP/kg from 21 to 29 d (experiment 1) and 33 to 43 d (experiment 2). 2. Measurements were made of growth rate, food intake, body composition, excreta production and N-tau-methylhistidine excretion as a measure of myofibrillar protein breakdown, and fractional rates (%/d) of protein deposition, breakdown and synthesis were calculated. 3. In experiment 1, there were no significant differences between the line means for the fractional measures of protein turnover, but there was marked differential response in the two lines in the fractional rates of protein deposition, breakdown and synthesis, to increase in protein intake. The positive slope of the regressions of fractional (%/d) protein deposition and synthesis rates on protein intake (g/d/kg BW) were approximately 1.4- and 2.0-fold higher respectively in the QL than the CL line birds, and the negative slope of the regression of fractional breakdown rate on protein intake was approximately threefold greater in the CL than the QL line birds. 4. In experiment 2, fractional deposition rate was 6.2% lower, but fractional breakdown rate 9.4% higher in the LL than the FL birds, whilst there was essentially no difference in response of the FL and LL birds in the components of protein turnover to increase in protein intake. Line differences in deposition and breakdown rates were thus a reflection of the considerably higher (20%) food and hence protein intake in the FL than the LL birds. 5. The differential line responses in protein turnover in the two experiments suggest that selection for increased breast muscle yield and for reduced body fatness manipulate different physiological pathways in relation to protein turnover, but neither selection strategy results in an improvement in net protein utilisation at typical levels of protein intake by birds on commercial broiler diets, through a reduction in protein breakdown rate.

Inglehart’s thesis of postmaterial value change is one of the most influential accounts of social and political change in advanced Western nations. This paper uses data from the World Values Survey and the Australian Election Surveys to reexamine the relationship between age and values in 19 advanced industrial nations. We find evidence of a monotonic age structuring of values in a number of countries, but in others, the relationship between age and values is not as Inglehart would predict. In addition, the impact of birth cohort on values differs between countries that are dominated by two major parties and those where there are many smaller parties. The presence of successful Green parties is also important for enhancing the uptake of postmaterialist values. These findings suggest that Inglehart’s arguments about generational value change should be modified to take into account national political institutions and political cultures that might enhance or impede generational-based values change.
