SINCE the publication in 1952 of Douglas McKie's Antoine Lavoisier, the standard biography which is of great value to all students of eighteenth-century science, there has been a steady increase in knowledge of most aspects of Lavoisier's life and work. This survey will be concerned ,mainly with monographs and papers in scientific and historical journals, but several important books may first be noted.

SummaryIn scientific circles in Paris and London large burning lenses were used in the eighteenth century as a means of reaching very high temperatures. However, their great expense proved to be unjustified, for chemists found that even in good weather they did not give reproducible results. This paper is concerned only with chemical applications of the lenses, and not with theoretical discussions of the means of eliminating aberration or calculating the temperatures attained.

In 1768 H. B. de Saussure studied chemistry with Baumé in Paris, and subsequently, using precise quantitative methods, he analysed minerals collected during his alpine journeys. He began to use the blowpipe in 1784, and later adapted it so that with a microscope and micrometer he could examine the effects of high temperatures on minute specimens of minerals. Analyses of air carried out with a portable eudiometer convinced him that air from alpine valleys contained more oxygen, and was therefore healthier, (...) than air from either mountain tops or plains. In 1788 he accepted the antiphlogistic theory after reading the annotated French translation of Kirwan's Essay on Phlogiston; he announced his conversion in a letter to the translator, Madame Lavoisier, whose reply is discussed and published here for the first time.

Ambient assisted living technologies can provide assistance and support to persons with dementia. They might allow them the possibility of living at home for longer whilst maintaining their comfort and security as well as offering a way towards reducing the huge economic and personal costs forecast as the incidence of dementia increases worldwide over coming decades. However, the development, introduction and use of AAL technologies also trigger serious ethical issues. This paper is a systematic literature review of the on-going scholarly (...) debate about these issues. More specifically, we look at the ethical issues involved in research and development, clinical experimentation, and clinical application of AAL technologies for people with dementia and related stakeholders. In the discussion we focus on: the value of the goals of AAL technologies, the special vulnerability of persons with dementia in their private homes, the complex question of informed consent for the usage of AAL technologies.

The eighteenth century saw the publication of many scientific and technical dictionaries, particularly in France, one of the most important being P. J. Macquer's Dictionnaire de chymie. Both the original text of 1766 and the revised and enlarged version of 1778 were translated into several languages, sometimes with authoritative notes and additions by the translators. No mere list of definitions, Macquer's work contained long articles that made it a comprehensive treatise on chemistry, and it set the pattern for many subsequent (...) chemical dictionaries. We have endeavoured to give an account of the circumstances in which the various editions, reprints and translations were published, and we add detailed bibliographical descriptions of them. Bibliographical purists consider that all the copies of a book printed from the same setting of type constitute an ‘edition’, and that there is a new edition when all or most of the type has been reset. However, Macquer described his revised and expanded text of 1778 as the ‘second edition’ and this designation has been adopted by subsequent writers, even though the original text was reprinted several times from different settings of type before 1778. In order to avoid confusion we therefore refer to all versions of the 1766 and 1778 editions as ‘issues’, ‘printings’ or ‘reprints’ of the first and second edition respectively. (shrink)

Autonomy seems to be a core issue for lifelogging technology as it can influence our understanding as well as our personal freedom but a comprehensive discussion on the effect of it on the autonomy of the lifelogger and others affected seems still missing in the current academic debate. In this article we provide a preliminary inquiry into this topic. First, the concept of lifelogging will be briefly clarified. In a lifelog, different data sources are combined in an archive that can (...) be used to retrieve information about the lifelogger and the environment in which the lifelogger is situated. Second, we will discuss the effect of lifelogs on an element of autonomy, namely understanding. Lifelogs can both advance understanding as well as hinder it. Information of lifelogs is the result of social processes that can bias information and can be used to manipulate lifeloggers. Third, we will discuss another aspect of autonomy, namely being free from controlling influences. Also on this level the effect of lifelogs is ambiguous. Fourth, we will discuss the conditions under which prospective lifelogger become lifeloggers. By discussing both the effect of lifelogs on autonomy as well as joining the community of lifeloggers we aim to show the many ways in which lifelogs can compromise and advance autonomy. Fifth, some recommendations are provided that aim to address the above mentioned concerns. (shrink)

In a lifelog, data from various sources are combined to form a record from which one can retrieve information about oneself and the environment in which one is situated. It could be considered similar to an automated biography. Lifelog technology is still at an early stage of development. However, the history of lifelogs so far shows a clear academic, corporate and governmental interest. Therefore, a thorough inquiry into the ethical aspects of lifelogs could prove beneficial to the responsible development of (...) this field. This article maps the main ethically relevant challenges and opportunities associated with the further development of lifelog technologies as discussed in the scholarly literature. By identifying challenges and opportunities in the current debate, we were able to identify other challenges and opportunities left unmentioned. Some of these challenges are partly explained by a blind spot in the current debate. Whilst the current debate focuses mainly on lifelogs held by individuals, lifelogs held by governmental institutions and corporations pose idiosyncratic ethical concerns as well. We have provided a brief taxonomy of lifelog technology to show the variety in uses for lifelogs. In addition, we provided a general approach to alleviate the ethical challenges identified in the critical analysis. (shrink)

But Srhas a relative angular velocity round the sun of l"-54 per minute (see Example 3); therefore, the relative angular velocity of A V round A is greater than this in the ratio of 7: 3, which gives an approximate result of 3"-6 per minute, the true rate being about 4" per minute. Annual ParaUax. 95. We have already seen that no displacement of the observer due to a change of position on the earth's surface could apparently affect the direction of a fixed star. However, as the earth in its annual motion describes an orbit of about 92 million miles radius round the sun, the different positions in space from which an observer views the fixed stars from time to time throughout the year must be separated...

The most remarkable fact about the universe is that certain parts of it are conscious. Somehow nature has managed to pull the rabbit of experience out of a hat made of mere matter. Making its own contribution to the current, lively debate about the nature of consciousness, Theories of Consciousness introduces variety of approaches to consciousness and explores to what extent scientific understanding of consciousness is possible. Including discussion of key figures, such as Descartes, Foder, Dennett and Chalmers, the book (...) covers identity theories, representational theories, intentionality, externalism, and the new information-based theories.

We show that as a chain of confirmation becomes longer, confirmation dwindles under screening-off. For example, if E confirms H1, H1 confirms H2, and H1 screens off E from H2, then the degree to which E confirms H2 is less than the degree to which E confirms H1. Although there are many measures of confirmation, our result holds on any measure that satisfies the Weak Law of Likelihood. We apply our result to testimony cases, relate it to the Data-Processing Inequality (...) in information theory, and extend it in two respects so that it covers a broader range of cases. (shrink)
