Why a right to life rules out infanticide: A final reply to Räsänen

Joona Räsänen has argued that pro‐life arguments against the permissibility of infanticide are not persuasive, and fail to show it to be immoral. We responded to Räsänen’s arguments, concluding that his critique of pro‐life arguments was misplaced. Räsänen has recently replied in ‘Why pro‐life arguments still are not convincing: A reply to my critics’, providing some additional arguments as to why he does not find pro‐life arguments against infanticide convincing. Here, we respond briefly to Räsänen’s critique of the substance view, and also to his most important claim: that possession of a right to life by an infant does not rule out the permissibility of infanticide. We demonstrate that this claim is unfounded, and conclude that Räsänen has not refuted pro‐life arguments against infanticide.     

A dubious defense of ‘after‐birth abortion’: A reply to Räsänen

Scholars have offered various critiques of Alberto Giubilini and Francesca Minerva's controversial article, ‘After‐birth abortion: Why should the baby live?’ My book The Ethics of Abortion: Women's Rights, Human Life, and the Question of Justice presents four such critiques. First, Giubilini and Minerva argue from the deeply controversial to the even more controversial. Second, they presuppose a false view of personal identity called body‐self dualism. Third, their view cannot secure human equality. And fourth, their account of harm cannot account for harm found in some cases of murder. In the article, ‘Pro‐life arguments against infanticide and why they are not convincing’, J. Räsänen examines and finds wanting these four critiques. This essay responds to Räsänen's defense of infanticide and argues that his responses to the four objections fail.     

A Critique of Henrik Friberg‐Fernros's Defense of the Substance View

Proponents of the substance view contend that abortion is seriously morally wrong because it is killing something with the same inherent value and right to life as you or I. Rob Lovering offers two innovative criticisms of the anti‐abortion position taken by the substance view – the rescue argument and the problem of spontaneous abortion. Henrik Friberg‐Fernros offers an interesting response to Lovering, but one I argue would be inconsistent with the anti‐abortion stance taken by most substance view theorists.     

Addiction,Heroin‐Assisted Treatment and the Idea of Abstinence: A reply to Henden

In our previous article on the question whether heroin addicts are able to give informed consent voluntarily to research on heroin‐assisted treatment, we criticized the ongoing bioethical discussion of a flawed conceptualization of heroin addicts' options. As a participant in this discussion, Edmund Henden defends the conceptualization as sufficient for determining whether heroin addicts are able to give informed consent to the research on heroin‐assisted treatment voluntarily. This discussion on research on heroin‐assisted treatment seems to go astray in several respects. In his reply to our article Henden maintains some of the biases, such as the necessity of abstinence in recovery, that seem to prevail in addiction research on a more general level as well. These biases run the danger of having implausible ethical implications on stakeholders in addiction research and treatment. In our reply to him, we will further clarify and discuss the importance of describing the relevant issues in plausible terms that do justice to the realities of the cases of informed consent in research on heroin‐assisted treatment and also raise a wider issue of the ethics of wording as well as of the narrow scope, or ‘tunnel vision’, in addiction research as currently conducted.     

Phylogenetic signals in thermal traits remain stronger in the tropics if we can believe published physiological data. A reply to McKechnie et al., “Data quality problems undermine analyses of endotherm upper critical temperatures”

Due to concerns about data quality, McKechnie, Coe, Gerson, and Wolf ( 2016 ) questioned the conclusions of our study (Khaliq et al., 2015 ) published in this journal. Here, we argue that most of the questioned data points are in fact useful for macrophysiological analyses, mostly because the vast majority of data are explicitly reported in the peer‐reviewed physiological literature. Furthermore, we show that our conclusions remain largely robust irrespective of the data inclusion criterion. While we think that constructive debates about the adequate use of primary data in meta‐studies as well as more transparency in data inclusion criteria are indeed useful, we also emphasize that data suitability should be evaluated in the light of the scope and scale of the study in which they are used. We hope that this discussion will not discourage the exchange between disciplines such as biogeography and physiology, as this integration is needed to address some of the most urgent scientific challenges.     

A novel electroconductive interface based on Fe3O4 magnetic nanoparticle and cysteamine functionalized AuNPs: Preparation and application as signal amplification element to minoring of antigen‐antibody immunocomplex and biosensing of prostate cancer

In this study, a novel electroconductive interface was prepared based on Fe₃O₄ magnetic nanoparticle and cysteamine functionalized gold nanoparticle. The engineered interface was used as signal amplification substrate in the electrochemical analysis of antibody‐antigen binding. For this purpose, biotinilated‐anti‐prostate‐specific antigen (PSA) antibody was bioconjugated with iron oxide magnetic nanoparticles (Fe₃O₄) and drop‐casted on the surface of glassy carbon electrode (GCE). Also, secondary antibody (HRP‐Ab2) encapsulated on gold nanoparticles caped by cysteamine was immobilized on the surface of GCE modified electrode. A transmission electron microscopy images shows that a sandwich immunoreaction was done and binding of Ab1 and Ab2 performed successfully. Various parameters of immunoassay, including the loading of magnetic nanoparticles, the amount of gold nanoparticle conjugate, and the immunoreaction time, were optimized. The detection limit of 0.001 μg. L^?1 of PSA was obtained under optimum experimental conditions. It is found that such magneto‐bioassay could be readily used for simultaneous parallel detection of multiple proteins by using multiple inorganic metal nanoparticle tracers and are expected to open new opportunities for early stage diagnosis of cancer in near future.
