Putnam says that "In one way of conceiving it, realism is an empirical theory." In the present work it is maintained that, in another way of conceiving it, realism is a grammatical thesis. That is, many of the principles taken to be definitive of realism, e.g., "Truth is objective," "Truth is mind-independent," Dummett's "a thought can be true only if there is something in virtue of which it is true," are what Wittgenstein would have called "grammatical remarks." They simply call (...) attention to certain features of the grammar of truth and related concepts. Thus, e.g., it is a feature of the way we use "is true" that statements are not spoken of as true for one person and not true for another. ;The character of grammar and of grammatical remarks in general is spelled out in some detail; it is argued in particular that Wittgenstein is not intending to provide, by means of these notions, a particular account of necessary truth. He is suggesting, rather, that looking upon certain philosophical claims as grammatical is a way of "deflating" them, stripping them of their appearance of profundity. Neither can grammatical remarks imply substantive philosophical theses. This is why realism, conceived as comprising grammatical remarks, does not imply scepticism, as is often supposed, and is not itself a controversial or exciting doctrine. ;There are of course some controversial formulations of realism, versions which are not simply underwritten by grammar. Thus some philosophers have held that, because the truth conditions of a proposition are essentially independent of any evidence we may have for the proposition, truth may not be accessible at all. I believe, however, that Putnam has shown, by means of an argument which is instructively viewed as a grammatical investigation, that truth is accessible, at least to an "ideal" theory. ;Recent expressions of idealism are argued to provide helpful accounts of language use and understanding, but fail to establish that truth is nothing but warranted assertibility, or that it must in some sense "arise within us." Such a conclusion runs afoul of the grammar of truth, of which realism is shown to provide the proper account. (shrink)

In “Risk Based Passenger Screening in Aviation Security: Implications and Variants of a New Paradigm”, Sebastian Weydner-Volkmann describes the current paradigm shift from ‘traditional’ forms of screening to ‘risk based passenger screening’ (RBS) in aviation security. This paradigm shift is put in the context of the wider historical development of risk management approaches. Through a discussion of Michel Foucault, Herfried Münkler and Ulrich Beck, Weydner-Volkmann analyses the shortcomings of such approaches in public security policies, which become especially (...) evident in the aviation security context. As he shows, the turn towards methods of RBS can be seen as an attempt to address a trade-off ‘trilemma’ between the effective provision of security, the implied costs for industry and passengers, and the ethical, legal and societal implications of the screening procedures. In order to analyse foreseeable outcomes of embracing RBS, he differentiates three prototypical variants of the new paradigm on the basis of their main referent and rationale. For each variant, he then subsequently assesses the implications for the ‘trilemma’, after having unveiled the criteria of analysis that will necessarily have to be followed within a serious appraisal of RBS methods.

Is evidential support transitive? The answer is negative when evidential support is understood as confirmation so that X evidentially supports Y if and only if p(Y | X) > p(Y). I call evidential support so understood “support” (for short) and set out three alternative ways of understanding evidential support: support-t (support plus a sufficiently high probability), support-t* (support plus a substantial degree of support), and support-tt* (support plus both a sufficiently high probability and a substantial degree of support). I also (...) set out two screening-off conditions (under which support is transitive): SOC1 and SOC2. It has already been shown that support-t is non-transitive in the general case (where it is not required that SOC1 holds and it is not required that SOC2 holds), in the special case where SOC1 holds, and in the special case where SOC2 holds. I introduce two rather weak adequacy conditions on support measures and argue that on any support measure meeting those conditions it follows that neither support-t* nor support-tt* is transitive in the general case, in the special case where SOC1 holds, or in the special case where SOC2 holds. I then relate some of the results to Douven’s evidential support theory of conditionals along with a few rival theories. (shrink)

Slater’s method is an integral part of the undergraduate experience. In actuality, Slater’s method is part of an atomic model and not simply a set of rules. Slater’s rules are a simple means for computing the effective nuclear charge experienced by an orbital. These rules are based on the shell-like structure of the Slater atom in which outer shell electrons are incapable of shielding inner electrons. Slater’s model provides a qualitative description of the valence electrons in multi-electron atoms with tremendous (...) ease. The model is useful for explaining atomic properties such as ionisation energy, electron affinity and atomic radius qualitatively. Slater’s rules also correctly reproduce the Madelung rule of filling and the ionisation sequence (4s before 3d); however, these rules are not able to reproduce the anomalous configurations of atoms such as Cr and Cu. It is found that the atomic properties that Slater’s model reproduces are all related to the exponential decay factor of the Slater orbital. We find—from estimating the polarity of a diatomic molecule using a simple model—that molecular polarity is related to the difference in the exponential decay factors of the valence orbitals of the two atoms, implying that the decay factor acts as the electronegativity of the atom.

Prenatal screening for foetal abnormalities such as Down's syndrome differs from other forms of population screening in that the usual aim of achieving health gains through treatment or prevention does not seem to apply. This type of screening leads to no other options but the choice between continuing or terminating the pregnancy and can only be morally justified if its aim is to provide meaningful options for reproductive choice to pregnant women and their partners. However, this aim (...) should not be understood as maximizing reproductive choice per se. Only if understood as allowing prospective parents to avoid suffering related to living with (a child with) serious disorders and handicaps can prenatal screening be a publicly or collectively funded programme. The alternative of moving prenatal testing outside the healthcare system into the private sector is problematic, as it makes these tests accessible only to those who can afford to pay for it. New developments in prenatal screening will have to be assessed in terms of whether and to what extent they either contribute to or undermine the stated aim of providing meaningful options for reproductive choice. In the light of this criterion, this article discusses the introduction of the new non‐invasive prenatal test (NIPT), the tendency to widen the scope of follow‐up testing, as well as the possible future scenarios of genome‐wide screening and ‘prenatal personalised medicine’. The article ends with recommendations for further debate, research and analysis. (shrink)

One widely held view of prenatal screening is that its foremost aim is, or should be, to enable reproductive choice; this is the Pure Choice view. The article critiques this position by comparing it with an alternative: Public Health Pluralism. It is argued that there are good reasons to prefer the latter, including the following. Public Health Pluralism does not, as is often supposed, render PNS more vulnerable to eugenics-objections. The Pure Choice view, if followed through to its logical (...) conclusions, may have unpalatable implications, such as extending choice well beyond health screening. Any sensible version of Public Health Pluralism will be capable of taking on board the moral seriousness of abortion and will advocate, where practicable, alternative means of reducing the prevalence of disease and disability. Public Health Pluralism is at least as well-equipped as the Pure Choice model to deal with autonomy and consent issues. (shrink)

This article brings a phenomenological perspective to the question of how bodily and inter-bodily experience is involved in interacting via audio-visual media like videoconferencing platforms. Contemporary discussions in interaction studies point to a certain suspension of bodily involvement in these mediated interactions, which leads to a visible loss of function in the case of gestures. Such observations have led phenomenologists to voice concern as to whether phenomenology is indeed still suited to account for the “digital world” in general. The following (...) article addresses these concerns by first making the case for a phenomenological understanding of gestures, which develops Merleau-Ponty’s notion of intercorporeality by drawing from an intersubjective reading of Husserl’s threefold analysis of the body (aesthesiological, kinaesthetic and orientational). Subsequently, these reflections are used to describe the modifications, which occur when interacting “through” the screen in videoconferences, by showing that they are not just privative in nature.

Prenatal screening pathways, as nowadays offered in most Western countries consist of similar tests. First, a risk-assessment test for major aneuploides is offered to pregnant women. In case of an increased risk, invasive diagnostic tests, entailing a miscarriage risk, are offered. For decades, only conventional karyotyping was used for final diagnosis. Moreover, several foetal ultrasound scans are offered to detect major congenital anomalies, but the same scans also provide relevant information for optimal support of the pregnancy and the delivery. (...) Recent developments in prenatal screening include the application of microarrays that allow for identifying a much broader range of abnomalities than karyotyping, and non-invasive prenatal testing that enables reducing the number of invasive tests for aneuploidies considerably. In the future, broad NIPT may become possible and affordable. This article will briefly address the ethical issues raised by these technological developments. First, a safe NIPT may lead to routinisation and as such challenge the central issue of informed consent and the aim of prenatal screening: to offer opportunity for autonomous reproductive choice. Widening the scope of prenatal screening also raises the question to what extent ‘reproductive autonomy’ is meant to expand. Finally, if the same test is used for two different aims, namely detection of foetal anomalies and pregnancy-related problems, non-directive counselling can no longer be taken as a standard. Our broad outline of the ethical issues is meant as an introduction into the more detailed ethical discussions about prenatal screening in the other articles of this special issue. (shrink)

Medical screening is justified on the strength of the assumption that the earlier disease is detected, the better it is for the patient. On examination, however, the assumption turns out to be severely flawed, and inadequate anyway, since it is not only the patient with whom we should be concerned, but healthy people as well. Instead of making assumptions about the ill, we should prove a test's overall benefit to the individual taking it before we recommend it.

Sober and Brandon et al. disagree about the role of screening-off in the appraisal of theories of natural selection. Some problems disregarded by them are unearthed in this discussion note.

Using an international sample of environmental and social firm-level ratings between 2007 and 2019, we form synthetic overlapping region-based equity portfolios to examine the impact of screening stringency on abnormal returns and specific risk. While previous literature analyzes this relationship in a bidimensional setting, inferences made in this study are additionally robust to regional levels of market efficiency. Our results suggest that (1) screening stringency displays an inverted curvilinear relationship with risk-adjusted returns and (2) the impact on specific (...) risk is strictly increasing. Thus, portfolios that employ marginal and substantial screening incur the cost of responsible investing. However, moderate screening has the benefit of increasing performance without the burden of financing the least responsible corporations. (shrink)

Develops a concept of revision, akin in spirit to AGM partial meet revision, but in which the postulate of 'success' may fail. The basic idea is to see such an operation as composite, with a pre-processor using a priori considerations to resolve the question of whether to revise, following which another operation revises in a manner that protects the a priori material.

Brandon ([1982] 1984, 1990) has argued that Salmon's (1971) concept of screening-off can be used to characterize (i) the idea that natural selection acts directly on an organism's phenotype, only indirectly on its genotype, and (ii) the biological problem of the levels of selection. Brandon also suggests (iii) that screening-off events in a causal chain are better explanations than the events they screen off. This paper critically evaluates Brandon's proposals.

This article is written in response to the idea that selective termination may be eugenic. It points out that a mixture of motives and goals may inform screening programmes and selective termination for fetal abnormality without the intention being “eugenic”. The paper locates modern genetics within the tradition of humanist medicine by suggesting that parents who choose to terminate a pregnancy because of fetal abnormalities are not making moral judgments about those who are living with these abnormalities already. Rather (...) they are making judgments about their own lives and the lives of their children in relation to this genetic disorder. It concludes by introducing several caveats about the counselling that parents receive after the results of the testing and suggests that counselling inevitably contains a directive element because of the nature of the information covered.

Whether ethical screening affects portfolio performance is an important question that is yet to be settled in the literature. This paper aims to shed further light on this question by examining the performance of a large global sample of Islamic equity funds from 1984 to 2010. We find that IEFs underperform conventional funds by an average of 40 basis points per month, consistent with the underperformance hypothesis. In line with popular media claims that Islamic funds are a safer investment, (...) IEFs outperformed conventional funds during the recent banking crisis. However, we find no such outperformance for other crises or high volatility periods. Based on fund holdings-based data, we provide evidence of a negative curvilinear relation between fund performance and ethical screening intensity, consistent with a return trade-off to being more ethical.

During the past decade, screening tests using computed tomography have disseminated into practice and been marketed to patients despite neither conclusive evidence nor professional agreement about their efficacy and cost-effectiveness at the population level. This phenomenon raises questions about physicians' professional roles and responsibilities within the setting of medical innovation, as well as the appropriate scope of patient autonomy and access to unproven screening technology. This article explores how physicians ought to respond when new screening examinations that (...) lack conclusive evidence of overall population benefit emerge in the marketplace and are requested by individual patients. To this end, the article considers the nature of evidence and how it influences decision-making for screening at both the public policy and individual patient levels. We distinguish medical and ethical differences between screening recommended for a population and screening considered on an individual patient basis. Finally, we discuss specific cases to explore how evidence, patient risk factors and preferences, and physician judgment ought to balance when making individual patient screening decisions. (shrink)

Although public law scholars have long addressed the problems of accountability generated by private decision-making and "privatization," they have largely ignored this phenomenon in the immigration context. Our ignorance is increasingly indefensible. Millions of employers - private parties - are required by law to screen their workers for unauthorized immigrants, and growing evidence suggests that they use their screening power to ignore workplace protections and to otherwise exploit these workers. This article is the first attempt to apply the insights (...) generated by the privatization literature to immigration law. It argues that our nation's employers have emerged as private immigration screeners who, like airport inspectors screening for ineligible entrants and law enforcement officers screening for criminal noncitizens, assist the Department of Homeland Security in identifying unauthorized workers for removal. More than just agents of exploitation, reframing employers as private screeners demonstrates that they are also agents of the state. Borrowing analytical concepts developing in the privatization literature, I argue that the high risk of abuse and the lack of readily available mechanisms for reducing that risk raise troubling implications over the kind of power that employers wield as private immigration screeners in the workplace. Reframing our nation's employers as private screeners gives theoretical coherence to the discretionary decision-making authority they actually wield, and explains why they have used that authority to exploit workers - as private parties carrying out public duties, they are incentivized to serve their own interests instead of verifying the immigration status of their workers in good faith. Examining the problem of private immigration screening also forces us to reconsider two aspects about immigration screening generally. First, although immigration law tends to reward unauthorized immigrants who lay low and tends to punish those who draw attention to themselves, I suggest that we ought to rethink this logic at least in the context of the workplace. Because workplace violations committed by employers are typically enforced by private parties, punishing unauthorized immigrants who attempt to assert these rights and thus draw attention to themselves, only encourages workplace violations by employers and fosters a culture of lawlessness. Second, thinking about how decision-making authority within immigration law should be allocated between the public and the private contributes to the current conversation over how similar decision-making authority should be allocated between federal entities and local entities. Although questions of accountability have lingered in the backdrop of the immigration federalism debate, I suggest that scholars would be well served to foreground these questions and answer them head-on.

Large-screen human-computer interaction technology is reflected in all aspects of daily life. The dynamic gesture tracking algorithm commonly used in recent large-screen interactive technologies demonstrates compelling results but suffers from accuracy and real-time problems. This paper systematically addresses these issues by a switching federated filter method that combines particle filtering and Mean Shifting algorithms based on a 3D sensor. Compared with several algorithms, the results show that the one-hand and two-hand large-screen gesture tracking based on the switched federated filtering algorithm (...) work well, and there is no tracking failure and loss of target. Therefore, the switching federated tracking positioning algorithm can be well applied to the design of human-computer interaction system and provide new ideas for future human-computer interaction.

Thinking on Screen: Film as Philosophy is an accessible and thought-provoking examination of the way films raise and explore complex philosophical ideas. Written in a clear and engaging style, Thomas Wartenberg examines films’ ability to discuss, and even criticize ideas that have intrigued and puzzled philosophers over the centuries such as the nature of personhood, the basis of morality, and epistemological skepticism. Beginning with a demonstration of how specific forms of philosophical discourse are presented cinematically, Wartenberg moves on to offer (...) a systematic account of the ways in which specific films undertake the task of philosophy. Focusing on the films The Man Who Shot Liberty Valance, Modern Times, The Matrix, Eternal Sunshine of the Spotless Mind, The Third Man, The Flicker , and Empire , Wartenberg shows how these films express meaningful and pertinent philosophical ideas. This book is essential reading for students of philosophy with an interest in film, aesthetics, and film theory. It will also be of interest to film enthusiasts intrigued by the philosophical implications of film. (shrink)

Prenatal screening can significantly benefit parents and the community. However, it has created a dilemma for women as it requires them to quickly decide whether to continue a pregnancy or terminate it should the test indicate a foetal abnormality. This can be psychologically traumatic for women torn between their connection to an unborn child with all its possible imperfections, and a desire to prevent its suffering as a disabled child in later life. A woman must also consider her own (...) and her family's future welfare. Extensive research into the physical aspects of prenatal screening has not explored the meaning of the experience for women or whether termination is the most appropriate option. This article examines recent qualitative studies, concluding that women who terminate a pregnancy following prenatal screening may experience an acute grief reaction or be plagued by guilt and fear that can precipitate marital breakdown. Additionally, there is a risk that through striving to eradicate congenital disability, a community risks promoting a cult of perfectionism that may have discriminatory effects on disabled people.

The Centers for Disease Control and Prevention (CDC) recently recommended that HIV screening should become routine for all adults in the United States. Implicit in the CDC proposal is the notion that pre-test counseling would be more limited than at present, and that written informed consent to screening would no longer be required. If widely implemented, routine testing would mark a tremendous shift in the US HIV screening strategy. There are a number of considerations used to determine (...) what screening tests should be routine, and HIV fits the bill in almost every regard. Yet the stigma associated with HIV infection remains, making the CDC's recommendation highly controversial. Will minimizing requirements for pre-test counseling and special written informed consent lead to unexpected or unwanted HIV testing, or do these stringent counseling and consent requirements needlessly scare people away? Will widespread and routine testing be associated with declining stigmatization, or will it drive some patients away from seeking desperately needed health care? These are high stakes questions, and we're about to find out the answers. (shrink)

Although prenatal screening is routinely undertaken as part of a woman's antenatal care, the ethics surrounding it are complex. In this paper, the author examines the Jewish position on the permissibility of several tests, including those for Down's syndrome and Tay-Sachs disease, the latter being especially common in the Jewish community. Clearly, the status of the tests depends on whether termination of affected pregnancies is allowed, and contemporary rabbinical authorities are themselves in dispute as to the permissibility of terminating (...) affected pregnancies. The nature of these arguments is examined and the author concludes that there are grounds on which the full range of prenatal screening is permitted in Jewish law. (shrink)

In the 21st century, the screen - the Internet screen, the television screen, the video screen and all sorts of combinations thereof - will be booming in our visual and infotechno culture. Screen-based art, already a prominent and topical part of visual culture in the 1990s, will expand even more. In this volume, digital art - the new media - as well as its connectedness to cinema will be the subject of investigation. The starting point is a two-day symposium organized (...) by the Netherlands Media Art Institute Montevideo/TBA, in collaboration with the _L&B _ series and the Amsterdam School of Cultural Analysis. Issues which emerged during the course of investigation deal with questions such as: How could screen-based art be distinguished from other art forms? Could screen-based art theoretically be understood in one definite model or should one search for various possibilities and/or models? Could screen-based art be canonized? What are the physical and theoretical forms of representation for screen-based art? What are the idiosyncratic concepts geared towards screen-based art? This volume includes various arguments, positions, and statements by artists, curators, philosophers, and theorists. The participants are Marie-Luise Angerer, Annette W.

In The Flesh of Images, Mauro Carbone analyzed Merleau-Ponty's interest in film as it relates to his aesthetic theory. Philosophy-Screens broadens the work undertaken in this earlier book, looking at the ideas of other twentieth-century thinkers concerning the relationship between philosophy and film, and also extending that analysis to address the wider proliferation of screens in the twenty-first century. In the first part of the book, Carbone examines the ways that Sartre, Merleau-Ponty, Lyotard, and Deleuze grappled with the philosophical significance (...) of cinema as a novel aesthetic medium unfolding in the twentieth century. He then considers the significance of this philosophical framework for understanding the digital revolution, in particular the extent to we are increasingly and comprehensively connected with screens. Smart phones, tablets, and computers have become a primary referential optical apparatus for everyday life in ways that influence the experience not only of seeing but also of thinking and desiring. Carbone's Philosophy-Screens follows Deleuze's call for "a philosophy-cinema" that can account for these fundamental changes in perception and aesthetic production, and adapts it to twenty-first century concerns.

The notion of probabilistic support is beset by well-known problems. In this paper we add a new one to the list: the problem of transitivity. Tomoji Shogenji has shown that positive probabilistic support, or confirmation, is transitive under the condition of screening off. However, under that same condition negative probabilistic support, or disconfirmation, is intransitive. Since there are many situations in which disconfirmation is transitive, this illustrates, but now in a different way, that the screening-off condition is too (...) restrictive. We therefore weaken this condition to what we call ‘partial’ screening off. We show that the domain defined by partial screening off comprises two mutually exclusive subdomains. In one subdomain disconfirmation is indeed transitive, but confirmation is then intransitive. In the other, confirmation is transitive, but here disconfirmation is once more intransitive. (shrink)

In this paper, we discuss the problem of communist power in so called totalitarian regimes. Inspired by strategies of explanation in contemporary science studies and by the ethnomethodological conception of social order, we suggest that the power of communists is not to be taken as an unproblematic source of explanation; rather, we take this power as something that is itself in need of being explained. We study personal narratives on political screenings that took place in Czechoslovakia in 1970 and analyze (...) how the power of communists obtained its strength from ordinary and “unremarkable” interactions between participants. The screenings are interpreted, in the terms of Bruno Latour, as “trials of strength.” We show that it was crucial for all the participants that associations, translations or mobilizations involved in making the regime real, remained partial and multiple, and not exclusive and “total” as is often assumed within dominant discourses on totalitarianism.

The discrepancy between children’s actual amount of viewing time and parents’ accounts of their concerns, rules, and parental mediation choices has been documented in empirical research, and typically interpreted through the lens of the Uses and Gratifications theory – showing how parents change their attitudes towards screen media in order to satisfy their own needs. Based on a qualitative longitudinal research project, including app-based media diaries, with 20 families with at least one child aged eight or younger, we aim to (...) make two contributions to the literature. With regard to theory, we aim to highlight the heterogeneous and contingent ways of balancing the place of digital media in children’s lives that arise from parents navigating screen time discourses, social pressures, and daily schedules. With regard to methods, we argue for the combination of qualitative data and app-based media diaries to contextualise and interpret potential discrepancies between reported screen time and parental anxieties or hopes about digital media.

According to Hugo Münsterberg, the direct application of experimental psychology to the practical problems of education, law, industry, and art belonged by definition to the domain of psychotechnics. Whether in the form of pedagogical prescription, interrogation technique, hiring practice, or aesthetic principle, the psychotechnical method implied bringing the psychological laboratory to bear on everyday life. There were, however, significant pitfalls to leaving behind the putative purity of the early psychological laboratory in pursuit of technological utility. In the Vocation Bureau, for (...) example, psychological instruments were often deemed too intimidating for a public unfamiliar with the inner workings of experimental science. Similarly, when psychotechnical means were employed by big business in screening job candidates, ethical red flags were raised about this new alliance between science and capital. This tension was particularly evident in Münsterberg's collaboration with the Paramount Pictures Corporation in 1916. In translating psychological tests into short experimental films, Münsterberg not only envisioned a new mass medium for the dissemination of psychotechnics, but a means by which to initiate the masses into the culture of experimental psychology.

With the new and highly accurate noninvasive prenatal test, new options for screening become available. I contend that the current state of the art of NIPT is already in need of a thorough ethical investigation and that there are different points to consider before any chromosomal or subchromosomal condition is added to the screening panel of a publicly funded screening program. Moreover, the application of certain ethical principles makes the inclusion of some conditions unethical in a privately (...) funded scheme, even if such screening would enhance a woman’s reproductive autonomy. On the one hand, a screening program aimed solely at the detection of Down syndrome is subject to the technological imperative and should be reassessed in the light of technologies that allow for the detection of conditions that are at least as severe. On the other hand, some chromosomal conditions should not be included in any screening programs, because this would violate certain ethical principles, such as the right of the future child to genetic privacy.

Thus, the DNA chip may be the key technology for a refined (...) preventive medicine as well as a new dimension of eugenics. The forthcoming introduction of the DNA chip technology into medical practice urgently requires an internationally consistent framework of ethical standards and legal limitations if we do not want it to become a new Pandora's box.

In the years following World War II, and increasingly during the 1960s and 1970s, professional scientific societies developed internal sub-committees to address the social implications of their scientific expertise. This article explores the early years of one such committee, the American Society of Human Genetics’ “Social Issues Committee,” founded in 1967. Although the committee’s name might suggest it was founded to increase the ASHG’s public and policy engagement, exploration of the committee’s early years reveals a more complicated reality. Affronted by (...) legislators’ recent unwillingness to seek the expert advice of human geneticists before adopting widespread neonatal screening programs for phenylketonuria, and feeling pressed to establish their relevance in an increasingly resource-scarce funding environment, committee members sought to increase the discipline’s expert authority. Painfully aware of controversy over abortion rights and haunted by the taint of the discipline’s eugenic past, however, the committee proceeded with great caution. Seeking to harness interest in and assert professional control over emerging techniques of genetic diagnosis, the committee strove to protect the society’s image by relegating ethical and policy questions about their use to the individual consciences of member scientists. It was not until 1973, after the committee’s modest success in organizing support for a retrospective public health study of PKU screening and following the legalization of abortion on demand, that the committee decided to take a more publicly engaged stance.

Effectiveness is a key criterion in assessing the justification of antibiotic resistance interventions. Depending on an intervention’s effectiveness, burdens and costs will be more or less justified, which is especially important for large scale population-level interventions with high running costs and pronounced risks to individuals in terms of wellbeing, integrity and autonomy. In this paper, we assess the case of routine hospital screening for multi-drug-resistant Gram-negative bacteria (MDRGN) from this perspective. Utilizing a comparison to screening programs for Methicillin-Resistant (...) Staphylococcus aureus (MRSA) we argue that current screening programmes for MDRGN in low endemic settings should be reconsidered, as its effectiveness is in doubt, while general downsides to screening programs remain. To accomplish justifiable antibiotic stewardship, MDRGN screening should not be viewed as a separate measure, but rather as part of a comprehensive approach. The program should be redesigned to focus on those at risk of developing symptomatic infections with MDRGN rather than merely detecting those colonised. (shrink)

Dental caries is the main oral health challenge for children in Nigeria. Concern about its negative impact makes screening for caries in children an attractive public health strategy. The ability to detect the preclinical phase of caries, the availability of screening tools with high accuracy, and the possibility of treatment before onset of clinical symptoms with significant cost and health benefits, makes it appropriate for screening. However in Nigeria, the poor availability of highly specific and sensitive (...) class='Hi'>screening tools, poor access to oral health care and concerns with pre-screening consent, raise the question of the appropriateness of conducting screening programmes for children. We argue that a number of structural challenges associated with poor uptake of oral health care services need to be addressed before screening for caries can be considered ethically appropriate. These include facilitating access of children to quality oral health care and a systematic national approach to oral health impl... (shrink)

Screen time has become a hot button issue in psychology with researchers fiercely debating its mental effects. If we want to understand the psychological dynamics of technology use, however, a numerical conceptualization of screen time will lead us to gloss over crucial distinctions. To make this point, the present article takes a hermeneutic approach to a negative form of screen time known as ‘phubbing’, which is the practice of snubbing conversational partners in favor of one’s phone. Using interview data, it (...) is demonstrated that whether or not phone use amounts to phubbing, that is, whether or not it tips over and becomes harmful, depends on a host of contextual factors such as relation (who), content (what), purpose (why), timing (when), and communication (how). These findings demonstrate that not all screen time is created equal: what is harmful and inappropriate in one context is benign in another, and vice versa. Simply put, screen time is not a numerical entity whose causal effects we can measure and explain, but a meaningful activity that we must try to understand. (shrink)

Eells and Sober proved in 1983 that screening off is a sufficient condition for the transitivity of probabilistic causality, and in 2003 Shogenji noted that the same goes for probabilistic support. We start this paper by conjecturing that Hans Reichenbach may have been aware of this fact. Then we consider the work of Suppes and Roche, who demonstrated in 1986 and 2012 respectively that screening off can be generalized, while still being sufficient for transitivity. We point out an (...) interesting difference between Reichenbach’s screening off and the generalized version, which we illustrate with an example about haemophilia among the descendants of Queen Victoria. Finally, we embark on a further generalization: we develop a still weaker condition, one that can be made as weak as one wishes. (shrink)

Newborn screening has evolved to include an increasingly complex spectrum of diseases, raising concerns that screening should be optional and require parental consent. Early detection of disorders like PKU and MCAD is essential to prevent serious disability and death in affected children. These are examples of high benefit-risk ratio disorders because of the irrefutable health benefits of early detection, coupled with the low risks of treatment. The dire consequences of not diagnosing an infant with a treatable disorder because (...) of parental refusal to screen are wholly unacceptable. Thus, we believe that newborn screening for disorders with high benefit-risk ratios should continue to be mandatory. (shrink)
