Context. The identification of the sources that reionized the Universe and their specific contribution to this process are key missing pieces of our knowledge of the early Universe. Faint star-forming galaxies may be the main contributors to the ionizing photon budget during the epoch of reionization, but their escaping photons cannot be detected directly due to inter-galactic medium opacity. Hence, it is essential to characterize the properties of faint galaxies with significant Lyman continuum photon leakage up to z 4 to (...) define indirect indicators allowing analogues to be found at the highest redshift. Aims. Long gamma-ray bursts explode typically in star-forming regions of faint, star-forming galaxies. Through LGRB afterglow spectroscopy it is possible to detect directly LyC photons. Our aim is to use LGRBs as tools to study LyC leakage from faint, star-forming galaxies at high redshift. Methods. Here we present the observations of LyC emission in the afterglow spectra of GRB 191004B at z = 3:5055, together with those of the other two previously known LyC-emitting LGRB, to determine their LyC escape fraction and compare their properties. Results. From the afterglow spectrum of GRB 191004B we determine a neutral hydrogen column density at the LGRB redshift of og =17:2 0:15, and negligible extinction. The only metal absorption lines detected are C iv and Si iv. In contrast to GRB 050908 and GRB 060607A, the host galaxy of GRB 191004B displays significant Ly emission. From its Ly emission and the non-detection of Balmer emission lines we constrain its star-formation rate to 1 SFR 4:7 M yr. 1. We fit the Ly emission with a shell model and find parameters values consistent with the observed ones. The absolute LyC escape fractions we find for GRB 191004B, GRB 050908 and GRB 060607A are of 0:35+0:10.0:11, 0:08+0:05.0:04 and :20+0:05.0:05, respectively. We compare the LyC escape fraction of LGRBs to the values of other LyC emitters found from the literature, showing that LGRB afterglows can be powerful tools to study LyC escape for faint high-redshift star-forming galaxies. Indeed we could push LyC leakage studies to much higher absolute magnitudes. The host galaxies of the three LGRB presented here have all M1600 >.19:5 mag, with the GRB 060607A host at M1600 >.16 mag. LGRB hosts may therefore be particularly suitable for exploring the ionizing escape fraction in galaxies that are too faint or distant for conventional techniques. Furthermore the time investment is very small compared to galaxy studies. (shrink)

Heintz & Scott-Phillips propose that the partner choice ecology of our ancestors required Gricean cognitive pragmatics for reputation management, which caused a tendency toward showing and expecting prosociality that subsequently scaffolded language evolution. Here, we suggest a cognitively leaner explanation that is more consistent with comparative data and posits that prosociality and eventually language evolved along with cooperative breeding.

Whether or not intellectual property rights ought, as a matter of political morality, to be protected by the law surely depends on what kinds of interests the various parties have in intellectual content. Although theorists disagree on the limits of morally legitimate lawmaking authority, this much seems obvious: the coercive power of the law should be employed only to protect interests that rise to a certain level of moral importance. We have such a significant interest in not being lied to, (...) for example, that ordinary unilateral lies are morally wrong, but the wrongness of lying does not rise to the level of something the state should protect against by coercive criminal prohibition. Indeed, it would clearly be wrong for the law to coercively restrict behaviors in which no one has any morally significant interests whatsoever. Using the coercive power of the law to restrict freedom is not justified unless the moral benefits of restricting the behavior outweigh the moral costs involved in using force to restrict human autonomy and freedom.

Over one hundred genes have been isolated from the human genome and shown to be causally related to specific human genetic diseases. Studies with gene‐specific probes have demonstrated that the mutations resulting in a particular phenotype are highly heterogeneous as a group, ranging from alterations in transcription or RNA processing in the nucleus, through to errors in mRNA translation in the cytoplasm. Even where the gene‐specific probe is not available, defects have been localized to chromosomal regions by family studies. Recently (...) developed methods for moving along the chromosome from a linked marker to the mutation are resulting in rapid advances in the understanding of many monogenic disorders. (shrink)

In this paper I have tried to clarify the meaning of two very different sets of characteristics which philosophers have had in mind when they claimed that ethical terms were objective. I gave a very tentative answer to the question whether it is true to say that, in any of the distinguished senses, ethical statements are objective. Lastly, I indicated how the failure to make the distinction I draw was responsible for a number of confusions and unnecessary difficulties. More precisely, (...) in (1) I defined the first set of the characteristics in question, which together I have called solidity ; in (2) I give reasons why it is misleading to claim that ethical statements are solid and also misleading to claim they are not; in (3) I defined the second set of these characteristics, namely, proper contentiousness and proper complexity; in (4) I explained what I thought were the fundamental differences between these two sets of characteristics; in (5) I suggested that the solidity of an expression is normally a good reason for holding that the expression is properly contentious and properly complex; in (6) I claim that the failure to understand (4) and, therefore, also (5) leads to the following errors: (a) that, if an expression is solid , it must be properly contentious and properly complex ; that, if an expression is non-solid , it must be either properly contentious and properly simple , or properly non-contentious . (5) That, if an expression is properly contentious and properly complex , it must be solid ; if it is properly contentious and properly simple or if it is properly non-contentious , then it must be non-solid ; and lastly in (7) I have mentioned some common reasons for holding that ethical expressions have one or the other of the above-mentioned characteristics.

The Danish theologian-philosopher K. E. Løgstrup is second in reputation in his homeland only to Søren Kierkegaard. He is best known outside Europe for his _The Ethical Demand_, first published in Danish in 1956 and published in an expanded English translation in 1997. _Beyond the Ethical Demand_ contains excerpts, translated into English for the first time, from the numerous books and essays Løgstrup continued to write throughout his life. In the first essay, he engages the critical response to _The Ethical (...) Demand,_ clarifying, elaborating, or defending his original positions. In the next three essays, he extends his contention that human ethics “demands” that we are concerned for the other by introducing the crucial concept of “sovereign expressions of life.” Like Levinas, Løgstrup saw in the phenomenon of “the other” the ground for his ethics. In his later works he developed this concept of “the sovereign expressions of life,” spontaneous phenomena such as trust, mercy, and sincerity that are inherently other-regarding. The last two essays connect his ethics with political life. Interest in Løgstrup in the English-speaking academic community continues to grow, and these important original sources will be essential tools for scholars exploring the further implications of his ethics and phenomenology. “K. E. Løgstrup’s work undoubtedly made in his time an original contribution to the field of moral philosophy and philosophy of religion. This translation makes extracts from his later publications on moral philosophy accessible to an English-speaking audience. I am again impressed by the depth of his ideas, which are certainly not outdated and still relevant for contemporary debates in moral philosophy.” —_Bert Musschenga, Vrije Universiteit, Amsterdam _ “Making a large part of Knud Løgstrup’s legacy accessible to the English-speaking public is an event of enormous cultural, philosophical and political importance—and we are all in debt to his disciple, Kies van Kooten Niekerk, and the University Press of Notre Dame, for making it happen. Løgstrup, alongside few other giants of 20th Century ethical thought, like Emmanuel Levinas or Hans Jonas, anticipated and articulated all the major challenges and urgent tasks with which the coming century is likely to confront the moral self. Our ethical discourse was all the poorer so far for being barred access to his findings and proposition. This will no longer be the case.” —_Zygmunt Bauman, emeritus, University of Leeds_ “The publication of an English translation of Knut Eljert Løgstrup's later works in ethics provides a wider readership with the opportunity to better understand his important contribution to ethics in the second half of the last century. With his notion of the _Sovereign Expressions of Life_ Løgstrup articulates his rejection of moral atomism that has become influential in recent times. The introduction and annotation by Kees van Kooten Niekerk are very helpful to see how Løgstrup's thought developed beyond _The Ethical Demand.” —__Hans S. Reinders, Vrije Universiteit, Amsterdam_.

The editor of the Russell journal summed up Modernist Heresies: British Literary History, 1883–1924z with his usual brevity during a (...) recent conversation : “The Wrst part is about Russell and the rest of it isn’t.” In fact the Wrst two chapters are only somewhat concerned with Russell, since he Wgures as part of the Heretical Cambridge scene with which Damon Franke opens this study, but, September 27, 2008 (1:09 pm) G:\WPData\TYPE2801\russell 28,1 048RED.wpd 90 Reviews after a Xeeting appearance of both Russells, Bertie and Dora, in the opening pages of Chapter 3, Bertie is not heard from again. Franke, who teaches English at the University of Southern Mississippi, has set himself an ambitious task, the scope of which is not fully captured in this book’s title. The selection of no fewer than ten subject headings in the cataloguing data for this studyz—zheadings ranging from “Modernism (Literature)” through “English Literature”, “Religion and Literature”, “Heresies, Christian”, and “Paganism in Literature”z—zprovides the wary reader withsome forewarning of its breadth. The author’s focus is on nothing less than the emergence and development of modernism in England, using the rise and demise of what Franke terms “heresy” as his barometer. Nor does the ascribed date range, 1883– 1924, prove much more accurate; in one of the most persuasive segments of the book, the After Words, Franke extends his examination, Wrst into the 1930s and then as far as 1949, the year that Orwell’s novel Nineteen Eighty-Fourz was published. Selecting as his starting point the 1883 blasphemy trial of G.yW. Foote, the editor of The Freethinker, at which the right to attack “even the fundamentals of religion” was enshrined in English law, providing that “the decencies of controversy” are observed (p. 10), Franke argues that this decision made possible “intellectual and literary forms of heresy which questioned the principles of religion ” (ibid.). His use of the term “heresy” for his wide ranging survey of philosophical and linguistic as well as literary opinion, provoked pause in this reader. The Oxford English Dictionary, the Wrst edition of which appeared the year after Foote’s heresy trial, provides a primary deWnition of heresy as follows: Theological or religious opinion or doctrine maintained in opposition, or held to be contrary, to the “catholic” or orthodox doctrine of the Christian Church, or, by extension, to that of any church, creed, or religious system, considered as orthodox. It is only through an extended deWnition of heresy that the door opens to allow Franke’s highly variable use of the term: “Opinion or doctrine in philosophy, politics, science, art, etc., at variance with those generally accepted as authoritative ” (OED Online, 2008). As will be demonstrated, aspects of thought which the less adventurous might prefer to call agnosticism, paganism or even atheism, are subsumed into the wide-ranging scope of this provocative study. The Cambridge Heretics, the group of which Russell was an Honorary Member, provides Franke with both his heretical cornerstone and his book’s opening chapters. In a skilfully contextualized examination, Franke documents the group’s Michaelmas 1909 genesis in the shadow, or perhaps in the intellectual light, of the Chawner ATairz—zthe Master of Emmanuel’s public expression of his personal loss of religious faith.
