New data on biogeography, classification and phylogeny of Рhysidae (Gastropoda: Hygrophila) = Новые данные биогеографии, классификации и филогении Рhysidae (Gastropoda: Hygrophila)

Physidae are a family of freshwater pulmonate gastropods with about 90-100 named species, newly divided among 23 genera in seven tribes and four clades. Morphological studies resulted in discovery of many new characters, some of them progressive, yielding criteria for primitive versus advanced states. Thus it is possible to assert that primitive groups are concentrated on the Pacific coast from Mexico to Costa Rica, and to trace the spread of lineages from this region to other parts of the world

Semicompatibilism and Moral Responsibility for Actions and Omissions: In Defence of Symmetrical Requirements

Although convinced by Frankfurt-style cases that moral responsibility does not require the ability to do otherwise, semicompatibilists have not wanted to accept a parallel claim about moral responsibility for omissions, and so they have accepted asymmetrical requirements on moral responsibility for actions and omissions. In previous work, I have presented a challenge to various attempts at defending this asymmetry. My view is that semicompatibilists should give up these defenses and instead adopt symmetrical requirements on moral responsibility for actions and omissions, and in this paper I highlight three advantages of doing so: first, it avoids a strange implication of the truth of determinism; second, it allows for a principled reply to Philip Swenson’s recent ‘No Principled Difference Argument’; third, it provides a reason to reject a crucial inference rule invoked by Peter van Inwagen’s ‘Direct Argument’ for the incompatibility of moral responsibility and determinism

Manipulation Arguments and Libertarian Accounts of Free Will

In response to the increasingly popular manipulation argument against compatibilism, some have argued that libertarian accounts of free will are vulnerable to parallel manipulation arguments, and thus manipulation is not uniquely problematic for compatibilists. The main aim of this article is to give this point a more detailed development than it has previously received. Prior attempts to make this point have targeted particular libertarian accounts but cannot be generalized. By contrast, I provide an appropriately modified manipulation that targets all libertarian accounts of freedom and responsibility—an especially tricky task given that libertarian accounts are a motley set. I conclude that if manipulation arguments reveal any theoretical cost then it is one borne by all accounts according to which we are free and responsible, not by compatibilism in particular

Slot configuration for axial-flow turbomachinery blades

Machining of slot in turbine blades of axial flow turbines to provide flow path between pressure and suction surfaces is discussed. Slot configuration and improvements in blade performance are described. Diagram of blade slot to show geometry of modification is included

[Review of] Michael P. Johnson and James P. Roark, eds. No Chariot Let Down: Charleston\u27s Free People of Color on the Eve of the Civil War

In an overgrown cemetery in the old village of Stateburg, South Carolina, a hundred miles north of Charleston lies the body of William Ellison (1790-1860), patriarch of a remarkable clan of free blacks whose achievements belie the myth of the Old South as a society of wealthy white masters and poor black slaves. Born a slave and perhaps the son of his master, Ellison early learned to make cotton gins and at age twentysix purchased his freedom and went into business in Stateburg. Riding the crest of the cotton boom, in 1835 he bought the handsome home of former governor Stephen D. Miller and by 1851 had also become a large cotton planter owning 800 acres of land and sixty-three slaves, more than any other free black except in Louisiana. He moved on an equal footing with white planters, eventually coming down from the colored balcony of Holy Cross Episcopal Church to sit with them

The Parallel Manipulation Argument

Matt King has recently argued that the manipulation argument against compatibilism does not succeed by employing a dilemma: either the argument infelicitously relies on incompatibilist sourcehood conditions, or the proponent of the argument leaves a premise of the argument undefended. This article develops a reply to King’s dilemma by showing that incompatibilists can accept its second horn. Key to King’s argument for the second horn’s being problematic is “the parallel manipulation argument.” I argue that King’s use of this argument is problematic, but I suggest that a (modified) parallel manipulation argument is effective for a different, though more restricted, purpose

Program to determine radiating, nonadiabatic, inviscid flow over a blunt body by the method of integral relations

Computer program performs the many calculations necessary for solving radiating, nonadiabatic flow of air in chemical equilibrium. Solution method provides accurate description of blunt body flow field in subsonic region

Atemporalism and dependence

It is widely thought that Atemporalism—the view that, because God is “outside” of time, he does not foreknow anything —constitutes a unique solution to the problem of freedom and foreknowledge. However, as I argue here, in order for Atemporalism to escape certain worries, the view must appeal to the dependence of God’s timeless knowledge on our actions. I then argue that, because it must appeal to such dependence, Atemporalism is crucially similar to the recent sempiternalist accounts proposed by Trenton Merricks, Philip Swenson, and Jonathan Westphal, and I conclude by briefly sketching some implications of this result
