    The officers and men of the British army that defended Canada from American invasion during the War of 1812 knew they were “forgotten soldiers.” Fighting in a distant and secondary theatre, far from the gaze of a government and public pre-occupied with events on the continent, especially in Spain, they took a somewhat perverse pride in their status as outcasts. As one quipped about the Duke of Wellington—“thank God he managed to do without us” at Waterloo. But they also took a particular pride in their own local heroes including such men as Gordon of the 1st Regiment of Foot, Robinson of the 8th Foot, Glew of the 41st, Fitzgibbon of the 49th, Morrison of the 89th, Dawson and Tweeddale of the 100th, Scott of the 103rd and—perhaps most renowned of all—Lieutenant Colonel William Drummond of the 104th Foot

    Cannabis shenanigans: advocating for the restoration of an effective treatment of pain following spinal cord injury.

    Get PDF
    Cannabis is an effective treatment for pain following spinal cord injury that should be available to patients and researchers. The major argument against the rescheduling of cannabis is that the published research is not convincing. This argument is disingenuous at best, given that the evidence has been presented and rejected at many points during the political dialog. Moreover, the original decision to criminalize cannabis did not utilize scientific or medical data. There is tension between the needs of a society to protect the vulnerable by restricting the rights of others to live well and with less pain. It is clear that this 70-year war on cannabis has had little effect in controlling the supply of cannabis. Prohibition can never succeed; it is a tyranny from which every independent mind revolts. People living with chronic pain should not have to risk addiction, social stigma, restrictions on employment and even criminal prosecution in order to deal with their pain. It is time to end the shenanigans and have an open, transparent discussion of the true benefits of this much-beleaguered medicine

    Appropriate Fiscal Policy over the Business Cycle: Proper Stimulus Policies Can Work

    Get PDF
    Fiscal policy has become quite controversial in the post-Keynesian era, the debate over the Obama stimulus package being a contentious recent example. Some pundits go so far as to take the position that macroeconomic theory has failed to meaningfully progress in terms of providing useful recommendations for policy-makers, particularly in times of recession. Others take the laissez-faire view that policy reactions to the business cycle do not help in a rational expectations world and indeed do harm by increasing uncertainty. Still others, while not necessarily viewing themselves as in any sense “Keynesian,” have a nagging feeling that sometimes doing nothing must be worse than doing something…but what to do? Sensible guidance is provided here on how governments should spend taxpayer dollars and on how that spending should change under varying economic conditions. The nature of public goods, namely whether they are complements, substitutes, or neutral to private goods, is seen to be critical to such decisions.fiscal policy, business cycles, public goods, recessions, boomtimes

    Benefit-Cost Analysis of Environmental Projects: A Plethora of Systematic Biases

    Get PDF
    There are many reasons to suspect that benefit-cost analysis applied to environmental policies will result in policy decisions that will reject those environmental policies. The important question, of course, is whether those rejections are based on proper science. The present paper explores sources of bias in the methods used to evaluate environmental policy in the United States, although most of the arguments translate immediately to decision-making in other countries. There are some “big picture” considerations that have gone unrecognized, and there are numerous more minor, yet cumulatively important, technical details that point to potentially large biases against acceptance on benefit-cost grounds of environmental policies that have true marginal benefits greater than true marginal costs, both in net present value terms. It is hoped that the issues raised here will improve future conduct of benefit-cost analyses of environmental policies.benefit-cost analysis, environmental policy, decision making, choice behavior, public goods, willingness-to-pay, willingness-to-accept, precautionary principle, hedonic methods, sum of specific damages, health effects model, environmental perceptions

    A Note on the Design of Experiments Involving Public Goods

    Get PDF
    Concern about potential free riding in the provision of public goods has a long history. More recently, experimental economists have turned their attention to the conditions under which free riding would be expected to occur. A model of free riding is provided here which demonstrates that existing experimental approaches fail to explore a potentially important real-world dimension of free riding. In a cash-in-advance economy, free riding becomes a two-stage problem, while existing experiments only address the second stage. That is, one would expect households with high demands for public goods relative to private goods to generate less income than households preferring ordinary private goods, because the former are unable to individually increment the public good and leisure is valuable. Existing experiments start with a given number of “tokens” for each decision-maker, effectively only addressing the second stage of the free riding problem, namely, under what conditions free riding becomes a problem out of a given income. A recommended solution to this problem is to incorporate the potential to generate income prior to (or simultaneously with) the decision of how to allocate that income between private and public goods.decision making, choice behavior, public goods, experimental economics, altruism, fairness, conditional reciprocity

    Application of pop-up satellite archival tag technology to estimate postrelease survival of white marlin (Tetrapturus albidus) caught on circle and straight-shank (“J”) hooks in the western North Atlantic recreational fis

    Short-duration (5- or 10-day) deployments of pop-up satellite archival tags were used to estimate survival of white marlin (Tetrapturus albidus) released from the western North Atlantic recreational fishery. Forty-one tags, each recording temperature, pressure, and light level readings approximately every two minutes for 5-day tags (n= 5) or four minutes for 10-day tags (n= 36), were attached to white marlin caught with dead baits rigged on straight-shank (“J”) hooks (n =21) or circle hooks (n=20) in offshore waters of the U.S. Mid-Atlantic region, the Dominican Republic, Mexico, and Venezuela. Forty tags (97.8%) transmitted data to the satellites of the Argos system, and 33 tags (82.5%) transmitted data consistent with survival of tagged animals over the deployment duration. Approximately 61% (range: 19−95%) of all archived data were successfully recovered from each tag. Survival was significantly (P<0.01) higher for white marlin caught on circle hooks (100%) than for those caught on straight-shank (“J”) hooks (65%). Time-to-death ranged from 10 minutes to 64 hours following release for the seven documented mortalities, and five animals died within the first six hours after release. These results indicate that a simple change in hook type can significantly increase the survival of white marlin released from recreational fi

    Application of Markov chain theory to ASTP natural environment launch criteria at Kennedy Space Center

    Get PDF
    To aid the planning of the Apollo Soyuz Test Program (ASTP), certain natural environment statistical relationships are presented, based on Markov theory and empirical counts. The practical results are in terms of conditional probability of favorable and unfavorable launch conditions at Kennedy Space Center (KSC). They are based upon 15 years of recorded weather data which are analyzed under a set of natural environmental launch constraints. Three specific forecasting problems were treated: (1) the length of record of past weather which is useful to a prediction; (2) the effect of persistence in runs of favorable and unfavorable conditions; and (3) the forecasting of future weather in probabilistic terms

    Statistical analysis of flight times for space shuttle ferry flights

    Get PDF
    Markov chain and Monte Carlo analysis techniques are applied to the simulated Space Shuttle Orbiter Ferry flights to obtain statistical distributions of flight time duration between Edwards Air Force Base and Kennedy Space Center. The two methods are compared, and are found to be in excellent agreement. The flights are subjected to certain operational and meteorological requirements, or constraints, which cause eastbound and westbound trips to yield different results. Persistence of events theory is applied to the occurrence of inclement conditions to find their effect upon the statistical flight time distribution. In a sensitivity test, some of the constraints are varied to observe the corresponding changes in the results

    Effect of nose bluntness and afterbody shape on aerodynamic characteristics of a monoplanar missile concept with bodies of circular and elliptical cross sections at a Mach number of 2.50

    Get PDF
    The tests were performed at a Mach number of 2.50 and at angles of attack from about -4 deg to 32 deg. The results indicate that increasing nose bluntness increases zero lift drag and decreases both the maximum lift-drag ratio and the level of directional stability. The center of pressure generally moves forward with increasing nose size; however, small nose radii on the modified elliptical configurations move the center of pressure rearward. The circular bodied configurations exhibit the greatest longitudinal stability and the least directional stability. Concepts with the variable geometry afterbody contour display the most directional stability and the greatest zero lift drag
