Do political factors influence public health expenditures? Evidence pre- and post-great recession.

This paper analyses whether government ideology and other political- and electoral-related factors influence country-level public healthcare expenditures, focussing on the impact of the Great Recession on that relationship. We test this hypothesis for the OECD countries in 1970-2016. Our results reveal the presence of a partisan effect, left-wing governments being more likely to raise public expenditures in the health sector. We also find that coalitions increase these expenditures, whilst minority governments and those with a high presence in the lower house decrease them. Meanwhile, the opportunistic behaviour of incumbents related to the timing of elections is not supported by our results. The percentage of public expenditures over total health expenditures is also examined, obtaining similar results regarding the partisan effect. However, the onset of the Great Recession has altered these relationships, neutralizing the impact of political factors.

Future climate scenarios for a coastal productive planktonic food web resulting in microplankton phenology changes and decreased trophic transfer efficiency.

We studied the effects of future climate change scenarios on plankton communities of a Norwegian fjord using a mesocosm approach. After the spring bloom, natural plankton were enclosed and treated in duplicates with inorganic nutrients elevated to pre-bloom conditions (N, P, Si; eutrophication), lowering of 0.4 pH units (acidification), and rising 3°C temperature (warming). All nutrient-amended treatments resulted in phytoplankton blooms dominated by chain-forming diatoms, and reached 13-16 µg chlorophyll (chl) a l-1. In the control mesocosms, chl a remained below 1 µg l-1. Acidification and warming had contrasting effects on the phenology and bloom-dynamics of autotrophic and heterotrophic microplankton. Bacillariophyceae, prymnesiophyceae, cryptophyta, and Protoperidinium spp. peaked earlier at higher temperature and lower pH. Chlorophyta showed lower peak abundances with acidification, but higher peak abundances with increased temperature. The peak magnitude of autotrophic dinophyceae and ciliates was, on the other hand, lowered with combined warming and acidification. Over time, the plankton communities shifted from autotrophic phytoplankton blooms to a more heterotrophic system in all mesocosms, especially in the control unaltered mesocosms. The development of mass balance and proportion of heterotrophic/autotrophic biomass predict a shift towards a more autotrophic community and less-efficient food web transfer when temperature, nutrients and acidification are combined in a future climate-change scenario. We suggest that this result may be related to a lower food quality for microzooplankton under acidification and warming scenarios and to an increase of catabolic processes compared to anabolic ones at higher temperatures.
