United States public health experts have long expressed concern about the prevalence of the human immunodeficiency virus among injection drug users. The United States has the largest reported IDU population in the world: 1.1 to 1.5 million. Recent estimates from the Centers for Disease Control and Prevention suggest that 50 percent of incident HIV infections occur among IDUs, with additional infections occurring among their sex partners and offspring. More than 33 percent of new AIDS cases occur in IDUs, their sexual (...) partners, and their children. Almost one half of all women diagnosed with AIDS in the United States are IDUS. Many of the remaining infected women were infected as a result of sex with a male IDU.While public health agencies, legislators, community leaders, and religious groups have engaged in vigorous debate over the merits of needle exchange programs as an intervention to reduce HIV transmission, the programs, some legal and some illegal, have been implemented in fifty-five cities across the country.

In this essay an ‘objective’ account of intrinsic value is proposed and partly defended. It is claimed that a kind of value exists which is, or may reasonably be supposed to be, a property of certain objects. The presence of such value is not to be wholly accounted for as the ‘projection’ of certain human feelings elicited by the object thought to be of value, nor by the object's meeting certain operative human conventions prescribing what is to be admired, nor (...) by its being conformable, in some way, to human needs or desires. Hume, of course, would have none of this. It is hoped to show that if one adopts Hume's account, then his attempt to show that there nevertheless will be convergence in the long run as to what is of aesthetic value is forced and unsuccessful. By contrast, on the ‘objective’ account convergence is to be expected. This, of course, only shows the superiority of the ‘objective’ account so long as there is an expectation of long-term convergence. This is not an expectation of most contemporary value ‘subjectivists’, and therefore the argument will not be directly relevant to their positions. (shrink)

Mill says that the object of his essay On Liberty is to defend a certain principle, which I will call the ‘liberty principle’, and will take to say the following: ‘It is permissible, in principle, for the state or society to control the actions of individuals “only in respect to those actions of each, which concern the interest of other people”’. The liberty principle is a prescription of intermediate generality. Mill intends it to support more specific political prescriptions, such as (...) liberty of conscience, of expressing and publishing opinions, of framing a plan of life to suit our own character, and of combination for any purpose not involving harm to others. The liberty principle is more general than these prescriptions but less general than its possible moral foundations, such as utilitarianism. My concern will be with attempts to defend the liberty principle by showing it to be supported by an acceptable moral position. (shrink)

If the world were wholly just, the following inductive definition would exhaustively cover the subject of justice in holdings.1. A person who acquires a holding in accordance with the principle of justice in acquisition is entitled to that holding.2. A person who acquires a holding in accordance with the principle of justice in transfer, from someone else entitled to the holding, is entitled to the holding.3. No one is entitled to a holding except by applications of i and 2.The complete (...) principle of distributive justice would say simply that a distribution is just if everyone is entitled to the holdings they possess under the distribution.

I begin by examining perception of photographs from two directions: what we think photographs are, and the aspects of mind involved when viewing photographs. Traditional photographs are shown to be mnemonic tools, and memory identified as a key part of the process by which photographs are fully perceived. Second, I describe the metamorphogram; a non-traditional photograph which fits specific, author-defined criteria for being memory. The metamorphogram is shown to be analogous to a composite of all an individual’s episodic memories. Finally, (...) using the metamorphogram in artistic works suggests a bi-directional relationship between individual autobiographical memory and shared cultural memory. A model of this relationship fails to align with existing definitions of cultural memory, and may represent a new form: sociobiographical memory. I propose that the experiences documented here make the case for promoting a mutually beneficial relationship between philosophy and other creative disciplines, including photography. (shrink)

Successful prototype marine chronometers, developed by Harrison and others in the eighteenth century, stimulated a sector of the British watchmaking industry to supply Admiralty and commercial demand for this instrument. Chronometers, like other British-made timepieces, were constructed by an elaborate pre-industrial method of production. The instrument's static technology and extreme durability meant replacement demand was minimal, and new demand was low relative to existing stock and the industry's capacity. The First World War created a final surge of demand that left (...) supplies far in excess of peacetime needs; and a new technology—radio transmissions of time signals—offered an alternative method of determining Greenwich time, and thus longitude, at sea.
