Effects of Oxygen on Nodule Physiology and Expression of Nodulins in Alfalfa1

Early nodulin 2 (ENOD2) transcripts and protein are specifically found in the inner cortex of legume nodules, a location that coincides with the site of a barrier to O2 diffusion. The extracellular glycoprotein that binds the monoclonal antibody MAC236 has also been localized to this site. Thus, it has been proposed that these proteins function in the regulation of nodule permeability to O2 diffusion. It would then be expected that the levels of ENOD2 mRNA/protein and MAC236 antigen would differ in nodules with different permeabilities to O2. We examined the expression of ENOD2 and other nodule-expressed genes in Rhizobium meliloti-induced alfalfa nodules grown under 8, 20, or 50% O2. Although there was a change in the amount of MAC236 glycoprotein, the levels of ENOD2 mRNA and protein did not differ significantly among nodules grown at the different [O2], suggesting that neither ENOD2 transcription nor synthesis is involved in the long-term regulation of nodule permeability. Moreover, although nodules from all treatments reduced their permeability to O2 as the partial pressure of O2 (pO2) was increased to 100%, the levels of extractable ENOD2 and MAC236 proteins did not differ from those measured at the growth pO2, further suggesting that if these proteins are involved in a short-term regulation of the diffusion barrier, they must be involved in a way that does not require increased transcription or protein synthesis.

German macro: how it's different and why that matters. EPC Discussion Paper, May 2016

Do the macroeconomics of the German political establishment really differ from standard western macroeconomics? That question was the starting point for the seminar on ‘German macro: How it’s Different and Why that Matters’, which was held at Heriot-Watt University in December 2015, with financial support from the Scottish Institute for Research in Economics (SIRE) and the Money, Macro & Finance Research Group (MMF). This ebook, edited by George Bratsiotis and David Cobham, is the result of that exercise; six of the papers were presented at the seminar in earlier versions, and the editors sought some additional papers to complete the range of perspectives offered. The authors all sought out to discover whether or not there is something unique about German macroeconomics, and in what ways it differs from standard western macroeconomics; is it true that the former neglects demand management (although it may be quite interventionist in other ways), rejects debt relief and emphasises structural reform designed to improve competitiveness as the (only) key to economic growth? How much of whatever difference exists is due to a well worked out set of ideas in the form of Ordoliberalism? In what way does it relate to Germany’s own experiences in different periods? And how far is this the result of political preferences and how much do the idiosyncrasies of these German views matter, for the development of the Eurozone and indeed the health of the German economy?

Effects of phosphorus on the growth and nitrogen fixation rates of Lyngbya majuscula: implications for management in Moreton Bay, Queensland

Significant acetylene reduction and therefore N-2 fixation was observed for Lyngbya majuscula only during dark periods, which suggests that oxygenic photosynthesis and N-2 fixation are incompatible processes for this species. Results from a series of batch and continuous-flow-culture reactor studies showed that the specific growth rate and N-2 fixation rate of L, majuscula increased with phosphate (P-PO4) concentration up to a maximum value and thereafter remained constant. The P-PO4 concentrations corresponding to the maximum N-2 fixation and maximum growth rates were -0.27 and -0.18 muM respectively and these values are denoted as the saturation values for N-2 fixation and growth respectively. Regular monitoring studies in Moreton Bay, Queensland, show that concentrations Of P-PO4 generally exceed these saturation values over a large portion of the Bay and therefore, the growth of the bloom-forming L, majuscula is potentially maximised throughout much of the Bay by the elevated P-PO4 concentrations. Results from other studies suggest that the elevated P-PO4 concentrations in the Bay can be largely attributed to discharges from waste-water treatment plants (WWTPs), and thus it is proposed that the control of the growth of L. majuscula in Moreton Bay will require a significant reduction in the P load from the WWTP discharges. If the current strategy of N load reduction for these discharges is maintained in the absence of substantial P load reduction, it is hypothesised that the growth of L, majuscula and other diazotrophs in Moreton Bay will increase in the future.

The effects of caffeine consumption on direct and indirect majority and minority influence

A study is reported that examines the effect of caffeine consumption on majority and minority influence. In a double blind procedure, 72 participants consumed an orange drink, which either contained caffeine (3.5mg per kilogram of body weight) or did not (placebo). After a 40-minute delay, participants read a counter-attitudinal message (antivoluntary euthanasia) endorsed by either a numerical majority or minority. Both direct (message issue, i.e., voluntary euthanasia) and indirect (message issue-related, i.e., abortion) change was assessed by attitude scales completed before and after exposure to the message. In the placebo condition, the findings replicated the predictions of Moscovici's (1980) conversion theory; namely, majorities leading to compliance (direct influence) and minorities leading to conversion (indirect influence). When participants had consumed caffeine, majorities not only led to more direct influence than in the placebo condition but also to indirect influence. Minorities, by contrast, had no impact on either level of influence. The results suggest that moderate levels of caffeine increase systematic processing of the message but the consequences of this vary for each source. When the source is a majority there was increased indirect influence while for a minority there was decreased indirect influence. The results show the need to understand how contextual factors can affect social influence processes.

Effects of government regulations, market orientation and ownership structure on corporate social responsibility in China:an empirical study

Previous research on corporate social responsibility mainly focuses on its nature and impact on business performance. This paper reports on a study that contributes to our understanding of the determinants of corporate social responsibility by focusing specifically on the role played by three strategically important variables, namely government regulation, ownership structure and market orientation. Results of a survey of 586 general managers of hotels in China suggest that the market orientation is the most significant predicator of corporate social responsibility followed by government regulation. In contrast, the ownership structure is found to have little effect. The implications of the findings for managers in China are discussed.
