    The incentives for governments to impose subsidies and tariffs on R&D and output is analyzed in a differentiated good industry where firms invest in a cost saving technology. When government commitment is credible, subsidies to R&D and output are positive both under Bertrand and Cournot competition. In the absence of government commitment the policy instrument is a tariff under Bertrand, and a subsidy under Cournot, competition. However, welfare under free trade is always greater than imposing a tariff unilaterally, or bilaterally, and hence non-committal under price competition is never an equilibrium. If a government has to choose either a subsidy on R&D (or on output) then, independent of price or quantity competition, it subsidies R&D for low levels of product substitutability and output for higherlevels of substitutability.Product differentiation; Trade policies; Commiment; Tariffs; Subsidies;

    Searching for improvements in semen cryopreservation, natural substances are commonly studied focusing to improve the sperm quality. The aim of this study were evaluated the effect of adding orange, pineapple, and beet juices in different concentrations and combinations to the ram semen cryopreservation extender. Five ejaculates from five adult rams were used. The semen pool was diluted in egg yolk-based extender and mixed with the following 15 treatments (at a final concentration of 400.10⁶ sptz/mL): orange 10% (O10) and 15% (O15); pineapple 10% (P10) and 15% (P15); beet 10% (B10) and 15% (B15); pineapple + orange 10% (PO10) and 15% (PO15); pineapple + beet 10% (PB10) and 15% (PB15); beet + orange 10% (BO10) and 15% (BO15); pineapple + beet + orange 10% (PBO10) and 15% (PBO15); and the control group (CON). Post-thaw in 0.25 mL straws semen quality analysis of cryopreserved semen was performed by CASA and flow cytometry. Analysis of variance (PROC GLM) was carried out and the averages were compared using the SNK test. Pearson's correlation test was also performed. No effect was noted in the addition of juices to the semen extender prior to cryopreservation. Post-thawed, although, statistically similar to the control group, the total motility of the B10 group reached acceptable standards of total motility. In addition, B10 group showed the highest values (p<0.05) of progressive motility than control group or other treatments. The addition of 10% beet juice to the ram semen extender can improve the cryopreservation of sperm motility. Keywords: antioxidant; freezing; sperm; semen extender

    Funder: European Society of Intensive Care Medicine; doi: http://dx.doi.org/10.13039/501100013347Funder: Flemish Society for Critical Care NursesAbstract: Purpose: Intensive care unit (ICU) patients are particularly susceptible to developing pressure injuries. Epidemiologic data is however unavailable. We aimed to provide an international picture of the extent of pressure injuries and factors associated with ICU-acquired pressure injuries in adult ICU patients. Methods: International 1-day point-prevalence study; follow-up for outcome assessment until hospital discharge (maximum 12 weeks). Factors associated with ICU-acquired pressure injury and hospital mortality were assessed by generalised linear mixed-effects regression analysis. Results: Data from 13,254 patients in 1117 ICUs (90 countries) revealed 6747 pressure injuries; 3997 (59.2%) were ICU-acquired. Overall prevalence was 26.6% (95% confidence interval [CI] 25.9–27.3). ICU-acquired prevalence was 16.2% (95% CI 15.6–16.8). Sacrum (37%) and heels (19.5%) were most affected. Factors independently associated with ICU-acquired pressure injuries were older age, male sex, being underweight, emergency surgery, higher Simplified Acute Physiology Score II, Braden score 3 days, comorbidities (chronic obstructive pulmonary disease, immunodeficiency), organ support (renal replacement, mechanical ventilation on ICU admission), and being in a low or lower-middle income-economy. Gradually increasing associations with mortality were identified for increasing severity of pressure injury: stage I (odds ratio [OR] 1.5; 95% CI 1.2–1.8), stage II (OR 1.6; 95% CI 1.4–1.9), and stage III or worse (OR 2.8; 95% CI 2.3–3.3). Conclusion: Pressure injuries are common in adult ICU patients. ICU-acquired pressure injuries are associated with mainly intrinsic factors and mortality. Optimal care standards, increased awareness, appropriate resource allocation, and further research into optimal prevention are pivotal to tackle this important patient safety threat

    Incentives for Cost Reducing Innovations under Quantitative Import Restraints

    The effect of trade quotas on firms' incentive to invest in cost-reducing R&D is studied in a two-stage price-setting duopoly game. A domestic and foreign firm first choose R&D levels and then set the prices of their differentiated products in the domestic market. With a quota imposed at, or close to, the free-trade level of imports, the domestic firm faces less competition than under free-trade and invests less in R&D. Contrarily, the constrained foreign firm invests more in R&D as the negative strategic effect of a reduction in its cost is now absent. These results differ partially from the Cournot duopoly case in which R&D expenditures are lower for both the firms. As the quota becomes more restrictive, the domestic firm increases and the foreign firm decreases its expenditures on R&D. Domestic welfare is always higher under free-trade than under any quota regardless of the degree of product substitutability.
