Alkyl nitrates have been observed in remote oceanic regions of the troposphere and in the surface ocean. The mechanism for their production in the oceans is not known. A likely source is the reaction of ROO + NO. Steady-state laboratory experiments show that alkyl nitrates are produced in the aqueous phase via this reaction, with branching ratios of 0.23 ± 0.04, 0.67 ± 0.03, and 0.71 ± 0.04 for methyl, ethyl, and propyl nitrate respectively. The branching ratios in aqueous solution are significantly higher than in the gas phase. Irradiation of surface seawaters yield rates of alkyl nitrate production on the order of 10-18 mol cm-3 s-1, suggesting that the reaction of ROO and NO is an important source of alkyl nitrates in seawater.

In her paper, The case for physician assisted suicide: not proven, Bonnie Steinbock argues that the experience with Oregon’s Death with Dignity Act fails to demonstrate that the benefits of legalising physician assisted suicide outweigh its risks. Given that her verdict is based on a small number of highly controversial cases that will most likely occur under any regime of legally implemented safeguards, she renders it virtually impossible to prove the case for physician assisted suicide. In this brief paper, we suggest some ways that may enable us to weigh the risks and benefits of legalisation more fairly and, hopefully, allow us to close the case for physician assisted suicide.

BACKGROUND: In its recent report 'Human Reproductive Technologies and the Law', the House of Commons' Select Committee on Science and Technology called for greater efforts to establish the potential demographic impact of sex selection across all sectors of UK society. Given the well-known preference for boys over girls among some communities, there is concern that a readily available service for social sex selection may upset the balance of the sexes. Of particular interest are the gender preferences and the demand for sex selection among Pakistanis. METHODS: We conducted a social survey on gender preferences and potential demand for preconception sex selection among 301 pregnant women in Karachi, Pakistan, using a self-report questionnaire consisting of 14 questions. RESULTS: About 41.5% wish to have a family with an equal number of boys and girls; 3.3% would like to have only boys, 1.0% only girls, 27.6% more boys than girls and 4.3% more girls than boys, and 22.3% stated that they do not care about the sex composition of their family. Whereas 6.3% could imagine employing cytometric sperm separation for social sex selection, 76.1% could not and 17.6% were undecided. About 27.2% felt that social sex selection ought to be legal, 48.8% thought it ought to be illegal and 23.9% were undecided. CONCLUSIONS: Although Pakistani women do show a statistically significant preference for boys over girls, the number of women willing to subject themselves to cytometric sperm separation appears to be too small to cause a severe imbalance of the sexes. However, further research among British citizens of Pakistani origin is needed to establish whether sex selection poses a serious threat to the sex ratio of UK communities.

Erst kürzlich hat uns Papst Benedikt XVI. noch einmal an die Hölle gemahnt. Sie existiere wirklich. Und jeder, der seine Augen vor Gottes Liebe verschließe, werde sich schon bald darin wiederfinden. Mit seiner ebenso charmanten wie amüsanten Sammlung von Aphorismen zeigt uns Edgar Dahl, dass dies kein Grund zur Sorge ist. Schließlich würden wir uns in der Hölle in weit besserer Gesellschaft befinden als im Himmel. Denn wir würden dort auf Sokrates, Platon und Aristoteles, Holbach, Hume und Schopenhauer, Voltaire, Goethe und Byron, Mozart, Haydn und Beethoven sowie auf Darwin, Freud und Einstein treffen. Dieses kleine Büchlein soll auf die uns bevorstehende Begegnung mit einigen der eminentesten Geister der Menschheitsgeschichte vorbereiten und uns mit deren skeptischen und bisweilen geradezu blasphemischen Gedanken vertraut machen. In diesem Buch zeigt Edgar Dahl, dass die Hölle eine weit bessere Adresse als der Himmel ist. Hans Albert (Autor von "Das Elend der Theologie")

In its recent statement 'Sex Selection and Preimplantation Genetic Diagnosis', the Ethics Committee of the American Society of Reproductive Medicine concluded that preimplantation genetic diagnosis for sex selection for non-medical reasons should be discouraged because it poses a risk of unwarranted gender bias, social harm, and results in the diversion of medical resources from genuine medical need. We critically examine the arguments presented against sex selection using preimplantation genetic diagnosis. We argue that sex selection should be available, at least within privately funded health care.

Preconception sex selection for non-medical reasons raises serious moral, legal and social issues. The main concerns include the threat of a sex ratio distortion due to a common preference for boys over girls, the charge of sexism, the danger of reinforcing gender stereotypical behaviour in sex selected children, and the fear of a slippery slope towards creating designer babies. This paper endeavours to show that none of the objections to preconception sex selection is conclusive and that there is no justification for denying parents the right to choose the sex of their prospective children.

Preconception sex selection is one of the most controversial issues in bioethics today. There is a widespread fear that a technology that allows parents to choose the sex of their children will have disastrous social effects. In its article “Gendercide: The Worldwide War on Baby Girls,” The Economist claimed that the advent of preconception sex selection will lead to a socially disruptive imbalance of the sexes in Asian and Arab countries. While it is true that prenatal diagnosis and selective abortions have led to a distorted sex ratio in countries such as India and China, it is unjustified to blame science for Asia’s social problems. It is religion not science that is responsible for the problems arising from new reproductive technologies, such as preimplantation genetic diagnosis or preconception sex selection.

Many people look to religion to help resolve the serious moral and legal issues associated with assisted reproductive technologies. Doing so presupposes that religion is the cornerstone of ethics, but this assumption is not well founded. While various faiths are entitled to articulate their views on matters of human reproduction, the contradictions involved in doing so make it unwise to rely on religion in the formulation of law and policy. These contradictions – such as the indeterminacy about what revealed truths means – make moral secular philosophy a better guide for the protection of human welfare.

Within the next parliamentary term, the German government is expected to replace the current Embryo Protection Act with a new Human Reproductive Technology Act. Before introducing new legislation, policy makers may want to survey public attitudes towards novel applications of reproductive technology. In order to assess opinions and concerns about preconception sex selection for non-medical reasons, a social survey has been conducted in Germany. As a representative sample of the German population, 1005 men and women 18 years and older were asked whether or not preconception sex selection should be made available. Of the respondents, 32% held that sex selection should be strictly prohibited, be it for medical or non-medical reasons, and 54% accepted the use of preconception sex selection for medical purposes. Only a minority of 11% approved of the use of preconception sex selection for non-medical reasons. The widespread opposition to a freely available service for non-medical sex selection is based on several claims: 87% of respondents hold that 'children are a gift and deserve to be loved regardless of any characteristics such as beauty, intelligence or sex'; 79% argue that choosing the sex of children is 'playing God'; 76% are opposed because it is seen as 'unnatural'; 49% are afraid that it is 'skewing the natural sex ratio'; and 40% consider it to be 'sexist'.

In a recent comment on the HFEA’s public consultation on sex selection, Soren Holm claimed that proponents of family balancing are committed to embrace a laissez faire approach. Given that arguments in support of sex selection for family balancing also support sex selection for other social reasons, advocates of family balancing, he asserts, are simply inconsistent when calling for a limit on access to sex selection. In this paper, I argue that proponents of family balancing are in no way inconsistent. Provided their advocacy of family balancing is aimed at preventing a severe distortion of the natural sex ratio, they are entirely justified in insisting on restrictions to sex selection. The real question is whether a concern for the sex ratio does indeed call for a limit on sex selection. Based on a recent survey on gender preferences and data from several Gender Clinics, I argue that a restriction on sex selection to family balancing is unwarranted. In the absence of any evidence for a pending sex ratio distortion, we are actually required to adopt a laissez faire approach to sex selection.

BACKGROUND Preconception sex selection for non-medical reasons is a controversial issue in bioethics. Little research has described preferences for preconception sex selection among Arab populations. This study describes the sex preference and interest in employing sex selection techniques among pregnant women in northern Jordan. METHODS A self-reported questionnaire was administered to 600 pregnant women in Irbid, Jordan. χ2 test and binary logistic regression were used to examine the factors associated with interest in preconception sex selection. RESULTS In general, the interest in using sex selection was low. Women who preferred boys were more likely to be interested in sex selection, if paid for by the couple [odds ratio (OR) = 4.40, 95% confidence interval (CI): 1.75–11.11] or by health insurance (OR = 3.42, 95% CI: 1.94–6.06), or, if feasible, administered through oral medication (OR = 8.84, 95% CI: 5.05–15.63). Women with lower education were more likely to be interested in sex selection, if paid by health insurance (OR = 1.96, 95% CI: 1.10–3.45) and were more likely to believe that sex selection is legal (OR = 1.79, 95% CI: 1.06–2.86). Women who had no boys were more likely to be interested in sex selection, if paid by health insurance (OR = 1.94, 95% CI: 1.10–3.42) or, if feasible, through medication (OR = 3.03, 95% CI: 1.82–5.00). CONCLUSIONS The majority of participants were not in favor of using preconception sex selection. Those with a preference to have boys, with lower education, and those with an imbalanced family were more likely to be interested in using sex selection technology.

In its recent report Human Reproductive Technologies and the Law, the House of Commons’ Select Committee on Science and Technology insisted that the United Kingdom ‘does not take a purely insular view’ on sex selection but to carefully consider the impact on other countries before allowing changes to current legislation. True, no country is an island, not even the British Isles. Still, outlawing a harmless practice in Great Britain because of its alleged harmful effects in other countries is bad public policy.
