Moral Responsibility, Justice, and Freedom

Freedom, and in particular, the freedom of human beings, is a hot topic within the field of metaphysics. In this paper, instead of arguing for the truth of a particular position on freedom, I explore whether a particular position, compatibilism, might be consistent with the existence of moral responsibility and retributive justice. To alleviate ambiguity, I construct a model by which the four primary positions on freedom might be clearly understood. I then distinguish between what I call ‘common-sense’ views of moral responsibility, and ‘complex’ views of moral responsibility. I select a particular complex view, which I term the ‘virtue’ theory of moral responsibility, offer some justification for the sensibility of such a theory, and demonstrate how the virtue theory is consistent with compatibilism. Finally, I propose that retributive justice is consistent with the virtue theory of moral responsibility, and consequently, that retributive justice is consistent with compatibilism

The Moral Argument, Existential Problems of Evil, and a Non-Existential Alternative

Within this paper, it is shown that certain ethical assumptions are implicit within the claim that certain kinds of evil exist. When taken in tandem with the moral argument for the existence of God, these assumptions can be arranged in such a way as to provide a contradiction. To avoid this contradiction, I posit a non-existential alternative to direct inductive arguments from evil, but the non-existential alternative gives rise to novel objections. When considering their respective ethical implications, both the existential and non-existential variations of direct inductive arguments fail. Since any direct inductive problem of evil must be either existential or non-existential, without an adequate response to such objections, the success of direct inductive arguments is greatly diminished

Glucoregulatory and order effects on verbal episodic memory in healthy adolescents after oral glucose administration

The ingestion of oral glucose has been observed to facilitate memory performance in both elderly individuals and in young adults. However, fewer studies have investigated the effect of glucose on memory in children or adolescents. In the present study, the ingestion of a glucose laden drink was observed to enhance verbal episodic memory performance in healthy adolescents under conditions of divided attention, relative to a placebo drink. Further analyses found that this glucose memory facilitation effect was observed only in adolescents exhibiting better glucoregulatory efficiency. These findings demonstrate that the glucose memory facilitation effect can be generalised to younger individuals. The importance of controlling for treatment order in within-subjects designs investigating the glucose memory enhancement effect is also discussed

The last glacial cycle: transient simulations with an AOGCM

A number of transient climate runs simulating the last 120kyr have been carried out using FAMOUS, a fast atmosphere-ocean general circulation model (AOGCM). This is the first time such experiments have been done with a full AOGCM, providing a three-dimensional simulation of both atmosphere and ocean over this period. Our simulation thus includes internally generated temporal variability over periods from days to millennia, and physical, detailed representations of important processes such as clouds and precipitation. Although the model is fast, computational restrictions mean that the rate of change of the forcings has been increased by a factor of 10, making each experiment 12kyr long. Atmospheric greenhouse gases (GHGs), northern hemisphere ice sheets and variations in solar radiation arising from changes in the Earth's orbit are treated as forcing factors, and are applied either separately or combined in different experiments. The long-term temperature changes on Antarctica match well with reconstructions derived from ice-core data, as does variability on timescales longer than 10 kyr. Last Glacial Maximum (LGM) cooling on Greenland is reasonably well simulated, although our simulations, which lack ice-sheet meltwater forcing, do not reproduce the abrupt, millennial scale climate shifts seen in northern hemisphere climate proxies or their slower southern hemisphere counterparts. The spatial pattern of sea surface cooling at the LGM matches proxy reconstructions reasonably well. There is significant anti-correlated variability in the strengths of the Atlantic Meridional Overturning Circulation (AMOC) and the Antarctic Circumpolar Current (ACC) on timescales greater than 10kyr in our experiments. We find that GHG forcing weakens the AMOC and strengthens the ACC, whilst the presence of northern hemisphere ice-sheets strengthens the AMOC and weakens the ACC. The structure of the AMOC at the LGM is found to be sensitive to the details of the ice-sheet reconstruction used. The precessional component of the orbital forcing induces ~20kyr oscillations in the AMOC and ACC, whose amplitude is mediated by changes in the eccentricity of the Earth's orbit. These forcing influences combine, to first order, in a linear fashion to produce the mean climate and ocean variability seen in the run with all forcings

Sequential Sales As a Test of Adverse Selection in the Market for Slaves

We propose an alternative test for adverse selection using notarial records for slaves sold in New Orleans in 1830. The experiment is simple and mimics the used car example originally proposed by Akerlof (1970). When first sold in New Orleans, buyers of imported slaves were uninformed of the slaves' unobservable characteristics. In time, the new owners learned more about their slaves and the "lemons" were sold and the "peaches" retained. Because buyers anticipate that the slaves offered for sale were of lower quality on average, they reduce their bids for these slaves. Consequently, we should observe a lower price for the slaves who were resold in the market. We test this proposition by linking the sequential sales records of 833 slaves sold in New Orleans. Through a comparison of initial and resale prices, we find that prices increased which suggests that adverse selection had a relatively small effect on the prices of slaves.slavery, human capital

Salience in Quality Disclosure: Evidence from the U.S. News College Rankings

How do rankings affect demand? This paper investigates the impact of college rankings, and the visibility of those rankings, on students' application decisions. Using natural experiments from U.S. News and World Report College Rankings, we present two main findings. First, we identify a causal impact of rankings on application decisions. When explicit rankings of colleges are published in U.S. News, a one-rank improvement leads to a 1-percentage-point increase in the number of applications to that college. Second, we show that the response to the information represented in rankings depends on the way in which that information is presented. Rankings have no effect on application decisions when colleges are listed alphabetically, even when readers are provided data on college quality and the methodology used to calculate rankings. This finding provides evidence that the salience of information is a central determinant of a firm's demand function, even for purchases as large as college attendance.

Gibbs entropy and irreversible thermodynamics

Recently a number of approaches has been developed to connect the microscopic dynamics of particle systems to the macroscopic properties of systems in nonequilibrium stationary states, via the theory of dynamical systems. This way a direct connection between dynamics and Irreversible Thermodynamics has been claimed to have been found. However, the main quantity used in these studies is a (coarse-grained) Gibbs entropy, which to us does not seem suitable, in its present form, to characterize nonequilibrium states. Various simplified models have also been devised to give explicit examples of how the coarse-grained approach may succeed in giving a full description of the Irreversible Thermodynamics. We analyze some of these models pointing out a number of difficulties which, in our opinion, need to be overcome in order to establish a physically relevant connection between these models and Irreversible Thermodynamics.Comment: 19 pages, 4 eps figures, LaTeX2
