Environmental Risks and Agricultural Commodities
No full textAs natural disasters are expected to increase both in severity and frequency, their impact on agricultural commodities and the food supply chain is likely to rise in tandem. We use a unique data set of natural disasters that occurred globally between 1970 and 2015 and study their impact on the price and price volatility of eight globally traded agricultural commodities that account for more than 75% of the food supply in the world. Our results show that price and the price volatility of commodities are impacted around the occurrence of a natural disaster in producing countries. In addition, we find that the affected country’s production shares, the total damage caused by a natural disaster relative to the affected country’s GDP, and the demand pressure for the commodity have an impact on the magnitude of price and price volatility changes of a given commodity around the occurrence of a natural disaster
The Soul and Its Powers: Aquinas Contra Aristotle
No full textThe Aristotelian view on the relation of the soul to its powers, as presented in De Anima, holds that the forms of organic beings are actualities in potential to further actualities. This view seems to conflict with his treatment of form in Metaphysics and other parts of De Anima, and so leaves us with the problem of the unity and actuality of the soul as form. Thomas Aquinas in his Summa Theologica holds a view on this topic differing from that of Aristotle. We see that Aquinas says powers are proper attributes of the soul. This view preserves the unity and causality of form. Aquinas is defended, especially through an elucidation of how proper attributes relate to the substantial form giving rise to them
Effects of Resistance Training on Mental Health and Sleep Outcomes among Women with Posttraumatic Stress Disorder
No full textWomen living with posttraumatic stress disorder (PTSD) face significant co-occurring mental health concerns and behavioral risk factors (e.g., poor sleep). Increasing evidence demonstrates that exercise can positively impact diverse health-related domains among populations with PTSD, yet analyses which examine these conditions among women are rare. To address this gap, this analysis examined the effects of a 3-week resistance training program on depression, anxiety, sleep, and PTSD among women who screened positive for PTSD. This investigation analyzed pooled data from two methodologically similar randomized controlled trials (i.e., a pilot and a replication study). Participants (n = 40) were randomly assigned to exercise (n = 20) or non-exercise time-matched control (n = 20). Data were analyzed with repeated-measures analysis of variance (ANOVA). Results revealed significant improvements in depression, F(1, 32) = 5.47, p = .02; anxiety, F(1, 32) = 7.75, p = .009; and sleep, F(1, 32) = 12.62, p = .001, from pre-post intervention in the intervention group relative to controls. Significant improvements were also found pre-post intervention in PTSD symptoms in both exercise and control groups, F(1, 32) = 52.63, p \u3c .001. Findings suggest that exercise improves mental health and sleep among women with PTSD. Taken together, these results suggest that exercise may be used as a therapeutic treatment option for women with PTSD
