The increasing demand for horticultural products for nutritional and economic purposes by lesser developed countries (LDC's) is well-documented. Technological demands of the LDC's producing horticultural products is also increasing. Pesticide use is an integral component of most agricultural production, yet chemicals are often supplied without supplemental information vital for their safe and efficient implementation. Illiteracy rates in developing countries are high, making pesticide education even more challenging. For women, who perform a significant share of agricultural tasks, illiteracy rates are even (...) higher than for men. The dilemma exists of how a developing country can improve its nutritional and economic situation without giving consideration to social and environmental consequences. (shrink)

Which are major debates in environmental ethics and why is necessary to put upside down the traditional anthropocentric/non- anthropocentric debate? Ecocentric ethic is not an anti-human position, and it has to become the global ethic: it's not a matter of economics but it's the common good, in a Socratic sense.

Here, an epidemiological model considering pro and anti-vaccination groups is proposed and analyzed. In this model, susceptible individuals can migrate between these two groups due to the influence of false and true news about safety and efficacy of vaccines. From this model, written as a set of three ordinary differential equations, analytical expressions for the disease-free steady state, the endemic steady state, and the basic reproduction number are derived. It is analytically shown that low vaccination rate and no influx to (...) the pro-vaccination group have similar impacts on the long-term amount of infected individuals. Numerical simulations are performed with parameter values of the COVID-19 pandemic to illustrate the analytical results. The possible relevance of this work is discussed from a public health perspective. (shrink)

The negative emotions generated following stressful life events can increase one’s risk of depressive symptoms and promote higher levels of perceived stress. The process model of emotion regulation can help distinguish between adaptive and maladaptive emotion regulation strategies to determine who may be at the greatest risk of worse psychological health across the lifespan. Heart rate variability may affect these relationships as it indexes aspects of self-regulation, including emotion and behavioral regulation, that enable an individual to dynamically adapt to the (...) changing demands of both internal and external environments. In this study, we expected individual differences in resting vagally mediated HRV to moderate the influence of emotion regulatory strategies among our sample of 267 adults. We found support for the hypothesis that higher vagally mediated HRV buffers against the typical adverse effects of expressive suppression when evaluating depressive symptoms and found weak support when considering perceived stress. There was no evidence for an interaction between cognitive reappraisal and vagally mediated HRV but there was a significant, negative association between cognitive reappraisal and depressive symptoms and perceived stress. Future work may determine if intervening on either emotion regulation strategies or HRV may change these within-persons over time. (shrink)

I argue that Davidson's anti-skeptical thesis can survive objections made against it by treating skepticism as logically possible, but not epistemically possible. That is, the skeptical hypothesis of massive error conflicts with what we must take ourselves to know if we are to have coherent thought and speech.

Evidence is currently mixed regarding the way in which cognitive conflict modulates the effect of emotion on task performance. The present study aimed to address methodological differences across previous studies and investigate the conditions under which interference from emotional stimuli can either be elicited or eliminated under high cognitive conflict. Four behavioural experiments were conducted with a university sample using a gender-discrimination stimulus-response compatibility task. In line with our previous findings, Experiment 1 found that when emotion and cognitive conflict conditions (...) were blocked, emotional faces increased reaction time interference during response compatible trials (low conflict) but not response incompatible trials (high conflict). However, when conflict and emotion conditions were randomised in different configurations across Experiments 2 (all trials randomised), 3 (emotion blocked, compatibility randomised) and 4 (compatibility blocked, emotion randomised), emotion interfered with task performance across both high and low conflict trials. These results suggest that predictability of both compatibility and emotion is required in order to obtain reduced emotional interference under high cognitive conflict. Consistent with prior reports, a top–down anticipatory control mechanism seems to be engaged in the presence of negative emotion when there are incompatible stimulus-response mappings. (shrink)

Uncertainties about how to achieve sustainable and reliable biobased value chains can be remedied by inclusion of local biomass producers. Such inclusion implies that the knowledge, values, interests and skills of these local producers are integrated into the set-up, design, development and associated distribution of risk and benefits of the specific value chain. To make sure that this inclusion is both fair and effective, capabilities of relevant actors need to be taken into account, i.e. the capabilities of biomass producers and (...) of companies and local governments. Building on these capabilities can lead to context sensitive design of biorefineries that allow for true inclusion of local stakeholders. We support this claim with reference to the case of sugarcane production in Jamaica. (shrink)

Jean Philiponus est un théologien monophysite du VIe siècle qui a commenté le De Anima d'Aristote. Il suit le traitement d'Aristote au sujet de la vue et de la lumière. Il se demande si l'oeil est purement un récepteur passif de lumière ou si il est un émetteur de rayons visuels en interaction avec l'objet et de ce fait rend la vision possible. Jean Philiponus en arrive à une nouvelle théorie de la vision où celle-ci apparaît comme une faculté en (...) interaction avec ce qui est vu en raison de la nature non corporelle de la lumière. On est ici au tout début de la controverse sur les images. (shrink)

Bredo C. Johnsen1 misconceives my strictures concerning acceptance of the following principle : If A both knows that p and knows that p entails q, then A can come to know that q.Johnsen seems unaware that my criticism was intended to apply only after is made to appear in its most plausible light; that is, only after its consequent is interpreted as: ’It is logically possible for A to know that q.’ Without this interpretation might be dismissed simply on the (...) grounds that A suffers from some physical or psychological disability that prevents him from drawing inferences from what he knows.Properly interpreted, remains acceptable as long as the propositions substituted for p and q are such that it is at least logically possible for A to get evidence enough to make them known. Agreement on this point is itself enough to render Johnsen's own examples irrelevant. For instance, even though it may be physically impossible for A to get adequate evidence that in the constellation Andromeda there is a planet intermediate in size between Venus and Earth, the foregoing is still a fit substitution instance for q; but since such a q does not suffice to falsify the consequent of, it does nothing to generate any skeptical argument, either.

I want to begin this paper by recalling a once-lively school of English political and legal thinking which has fallen undeservedly into neglect. I refer to the pluralists, notably the lawyer F. W. Maitland, the religious scholar J. N. Figgis, and, early in their careers, the political theorists Harold Laski and G. D. H. Cole. All were influenced by the writings of the German legal scholar Otto von Gierke, which Maitland as editor and translator had first introduced into England. The (...) pluralists' concerns were at once political and legal; virtually alone among English writers in this century until the 1970s, their work avoided the barrenness that comes of treating political theory and jurisprudence as unrelated enterprises. I shall describe the problems that preoccupied them and some of their resultant theories, and also the way in which specifically legal doctrine was both a target of their criticism and an important element in their thinking.
