To describe phenomena that occur at different time scales, computational models of the brain must incorporate different levels of abstraction. At time scales of approximately 1/3 of a second, orienting movements of the body play a crucial role in cognition and form a useful computational level embodiment level,” the constraints of the physical system determine the nature of cognitive operations. The key synergy is that at time scales of about 1/3 of a second, the natural sequentiality of body movements can (...) be matched to the natural computational economies of sequential decision systems through a system of implicit reference called deictic in which pointing movements are used to bind objects in the world to cognitive programs. This target article focuses on how deictic bindings make it possible to perform natural tasks. Deictic computation provides a mechanism for representing the essential features that link external sensory data with internal cognitive programs and motor actions. One of the central features of cognition, working memory, can be related to moment-by-moment dispositions of body features such as eye movements and hand movements. (shrink)

This paper focuses on the Korean suffix -te, which has been variously analyzed as a marker of tense, aspect, tense–aspect, mood, mood–tense, or evidentiality. I argue against all of these approaches and propose instead that -te is a spatial deictic past tense, which triggers an evidential environment. It refers to a certain past time when the speaker either observed an event or some evidence of the event within his (her) perceptual field. Thus, the denotation of -te is ‘overlap’, not (...) between the speaker's perceptual field and the event itself, but between the speaker's perceptual field and the evidence of the event at the past reference time. To account for this denotation, propose an ‘evidence trace’ function as well as a ‘speaker's perceptual trace’ function (cf. M. Faller, J Semantics 21:45–85, 2004). My analysis shows that suffixes like -ess (which is traditionally analyzed as a perfect) play two roles, as an indirect evidential and a perfect, depending on whether they appear with the spatial deictic tense -te or with a simple deictic tense. I argue that in Korean two distinct tense systems—the regular tense–aspect system and the spatial deictic tense–evidential system—exist in parallel. Thus the proposed analysis allows evidentials to be subsumed under the formal theory of tense, aspect, and mood. (shrink)

In this paper we address the issue of grounding for experiential concepts. Given that perceptual demonstratives are a basic form of such concepts, we examine ways of fixing the referents of such demonstratives. To avoid ‘encodingism’, that is, relating representations to representations, we postulate that the process of reference fixing must be bottom-up and nonconceptual, so that it can break the circle of conceptual content and touch the world. For that purpose, an appropriate causal relation between representations and the world (...) is needed. We claim that this relation is provided by spatial and object-centered attention that leads to the formation of object files through the function of deictic acts. This entire causal process takes place at a pre-conceptual level, meeting the requirement for a solution to the grounding problem. Finally we claim that our account captures fundamental insights in Putnam’s and Kripke’s work on “new” reference. (shrink)

This paper aims to analyze the deictic representations of person in the British and American media discourse, mostly focusing on such genres and subgenres as newspaper articles, interviews, letters to editors, opinions, headlines and advertisements. For this purpose, we wish to introduce a theoretical framework for the study and then we hope to present certain ways in which deictic expressions represent person. Theoretical framework for our study is based upon the socio-cognitive approach, which gives priority to individual practices (...) and subjectivity over social practices in discourse as well as the definition of discourse based on knowledge. The reason why we focus on the media discourse is obvious. The high degree of personalized conceptualization and contextualization dominated by a large number of subjective factors prevail in the above-mentioned genres and subgenres of media discourse. The deictic representations of person play the key role in this process. (shrink)

This essay introduces the concept of deictic abstraction , taking as a point of departure Husserl’s prototypical but insufficient description of the act of ideation in which a shade of color comes to givenness as an ideal object, i.e., a non-individual or abstract object, on the basis of a perceived individual object. This concept comprises not only color-ideation and ideations of universalities of the sensuous sphere , but all acts founded in perceptions in which ideal objects are directly referred (...) to by means of demonstrative expressions . This allows various types of deictic ideations or abstractions, corresponding to the degree of universality and the kind of ideal object concerned, to be brought to light through the analysis of particular cases of everyday acts of deictic abstraction, including deictic abstractions of predicative universals of the lowest level of universality ; deictic abstractions of non-predicative universals, especially of universal ways of doing something ; and deictic abstractions of individual styles of doing something . Deictic abstractions not only turn out to be constitutive for the formation of perceptual concepts of the lower and lowest levels, but also prove to be foundational for all kinds of learning in which schemata of actions are acquired from a model.

This paper proposes an approach to narrative deixis which offers a coherent analysis of the respective roles of proximal and distal deictic expressions. The paper starts by arguing that fictional narratives require an approach to deixis which modifies a number of broadly held assumptions, especially as regards the interaction between tense and other deictic forms. It then considers the widely discussed instance of the temporal adverb now in the context of Past Tense. The second part of the paper (...) gives special focus to demonstratives in narrative fiction, showing their role in temporal construals. It argues that both temporal and demonstrative expressions are primarily used to serve narrative viewpoint construction. Examples from several novels are then used to show how the proximal and distal choices of demonstratives, temporal adverbs and locative adverbs structure narrative viewpoint, including narrative representation of character experience. The paper concludes by proposing that in the context of fictional narratives the proximal/distal contrast is more relevant to meaning emergence than individual aspects of deixis, and that the construal of time can be achieved through the whole spectrum of deictic forms, not just tense and temporal adverbs such as now and then.

Many scholars continue to accord routine action a central role in social theory and defend the continuing relevance of Bourdieu's habitus. Simultaneously, most recognize the importance of reflexivity. In this article, I consider three versions of the effort to render these concepts compatible, which I term "empirical combination," "hybridization," and "ontological and theoretical reconciliation." None of the efforts is ultimately successful in analytical terms. Moreover, I argue on empirical grounds that the relevance of habitus began to decrease toward the end (...) of the 20th century, given major changes in the structures of the advanced capitalist democracies. In these circumstances, habitual forms prove incapable of providing guidelines for people's lives and, thus, make reflexivity imperative. I conclude by arguing that even the reproduction of natal background is a reflexive activity today and that the mode most favorable to producing it—what I call "communicative reflexivity"—is becoming harder to sustain.

Ballard et al. claim that fixations bind variables to cognitive pointers. I comment on three aspects of this claim: (1) its contribution to the interpretation of indexical language; (2) empirical support for the use of very few deictic pointers; (3) nonetheless, abstract pointers cannot be taken as prototypical cognitive representations.

It is unlikely that Ballard et al.'s embodiment theory has general applicability to cognition because it is based on experiments that neglect the importance of meaning, purpose, and learning in cognitive tasks. Limitations of the theory are illustrated with examples from everyday life and the results of recent experiments using cognitive and visuomotor tasks.

Berber languages use the directionals =d and =nn to specify the deictic path of motion verbs. These clitics occur with a range of verbs from other semantic classes (e.g. change of state verbs, verbs of vision and perception), with which they can be attributed different meanings. The first goal of this paper is to provide a cross-dialectal description of these meanings. The second goal is to show the role of verbal semantics in their constructions and the overall distribution of (...) the clitics. Adopting Talmy’s framework (2000) of lexicalisation of semantic concepts, linked to the domain of space and motion, I propose that the particular meaning components lexicalised by the modified verb govern the occurrence of the clitics and their particular meaning.

Much attention has been paid to ‘deictic shifts’ in Ancient Greek literary texts. In this article I show that similar phenomena can be found in documentary texts. Contracts in particular display unexpected shifts from the first to the third person or vice versa. Rather than constituting a narrative technique, I argue that such shifts should be related to the existence of two major types of stylization, called the ‘objective’ and the ‘subjective’ style. In objectively styled contracts, subjective intrusions may (...) occur as a result of the scribe temporarily assuming himself to be the deictic center, whereas in subjectively styled contracts objective intrusions may occur as a result of the contracting parties dictating to the scribe, and the scribe not modifying the personal references. There are also a couple of texts which display more extensive deictic alter­nations, which suggests that generic confusion between the two major types of stylization may have played a role. (shrink)

Walter Glannon argues that our proposal for routine recovery of transplantable cadaveric organs is unacceptable After carefully reviewing his counterarguments, we conclude that, although some of them have merit, none are sufficiently strong to warrant abandoning this plan. Below we respond to each of Glannon's concerns.

An ascent routine (AR) allows a speaker to self-ascribe a given propositional attitude (PA) by redeploying the process that generates a corresponding lower level utterance. Thus, we may report on our beliefs about the weather by reporting (under certain constraints) on the weather. The chief criticism of my AR account of self-ascription, by Alvin Goldman and others, is that it covers few if any PA’s other than belief and offers no account of how we can attain reliability in identifying our (...) attitude as belief, desire, hope, etc., without presupposing some sort of recognition process. The criticism can be answered, but only by giving up a tacit—and wholly unnecessary—assumption that has influenced discussions of ascent routines. Abandoning the assumption allows a different account of ARs that avoids the criticism and even provides an algorithm for finding a corresponding lower level utterance for any PA. The account I give is supported by research on children’s first uses of a propositional attitude vocabulary. (shrink)

This paper considers the ethics of routine antenatal HIV testing and the role of informed consent within such a policy in order to decide how we should proceed in this area—a decision that ultimately rests on the relative importance we give to public health goals on the one hand and respect for individual autonomy on the other.A recent illuminating qualitative study by Zulueta and Boulton1 explores the practicalities of informed consent in routine antenatal HIV testing. Its results support what I (...) have argued1 is inevitable with routine testing policies of this kind: that routine antenatal testing regimes are incompatible with requirements for informed consent. It has become clear that intervention could reduce the risk of transmitting HIV from mother to child from 15–20%2 to around 8%,3 or possibly as low as 2%.4,5 The evidence of this possibility produced a general trend towards introducing routine antenatal HIV screening in developed countries worldwide.6,7,8,9,10 The aim was to dramatically reduce the rate of HIV transmission from mother to child by encouraging universal antenatal HIV testing. The UK has been no exception, and in 1999 the government instructed health authorities to implement a policy of offering and recommending an HIV test to all pregnant women.11This UK antenatal screening policy and others like it, although well-meaning, are problematic in their formulation. In order to reflect contemporary ethical and legal practice, such policies attempt to marry the public health aims of maximising uptake of testing with a commitment to respect the choices of patients by requiring informed consent before they participate in screening. Thus, in the case of UK policy, health professionals are instructed to recommend the HIV test to all pregnant women in order to achieve the target of a 90% …. (shrink)

In the current debate about the pros and cons of routine (nonreligious) neonatal circumcision (RNC), the emphasis is on medical justifications for the practice. Questions of human rights also are widely discussed. However, even if the alleged medical benefits of RNC were to outweigh the harms and risks, this is not a sufficient justification for RNC. The practice of RNC is questionable from a variety of viewpoints including not only the ideal of evidence-based medicine and human rights considerations, but also (...) the notion of respect for bodily integrity.

The paper focuses on a specific type of referring legal provisions, in which the referring phrase contains a component that indicates the position of a certain fragment of the same text of a normative act by determining the position of that fragment in relation to the fragment in which the given referring phrase is located. Despite the fact that these referrals, called deictic, may be perceived as uncomplicated in structure and as functioning correctly in legal texts, many theoretical as (...) well as practical problems arise during their drafting and legal interpretation. The article attempts to reveal, organize and name these problems basing on the conceptual grid formulated by Studnicki, Łachwa, Fall and Stabrawa as a universal, although not widely known outside Polish jurisprudence, tool for analysing and solving referring provisions as elements of various legal systems, especially continental ones. Texts of selected Polish Codes have been chosen as an illustrative material of deictic referrals which have been incorrectly formulated as leaving space for interpretative doubts in terms of place of indication and place of reference, which also causes a potential problem of the deferred ostension phenomenon noticed by Quine. The author argues that proper drafting of referring legal provisions with deictic indication requires that the legislator should have extensive pragmalinguistic knowledge and is an essential part of law-making oriented towards achieving comprehensibility of texts of normative acts, especially as important as Codes.

In the UK, it has been proposed that alongside the current advice to abstain from alcohol completely in pregnancy, there should be increased screening of pregnant women for alcohol consumption in order to prevent instances of fetal alcohol spectrum disorder. The Scottish Intercollegiate Guidelines Network published guidelines in 2019 recommending that standardised screening questionnaires and associated use of biomarkers should be considered to identify alcohol exposure in pregnancy. This was followed in 2020 by the National Institute for Health and Care (...) Excellence Draft Quality Standard, which recommended that pregnant women should have information on their alcohol consumption recorded throughout their pregnancy and this information transferred to the child’s health records. Most recently, Public Health England has stated that the alcohol intake of all women should be recorded throughout pregnancy, not just at the initial booking appointment and that tools such as blood biomarkers and meconium testing should be researched in order to determine true prevalence rates of alcohol in pregnancy. We argue that this proposed enhanced screening undermines women’s autonomy and their legal right to be sufficiently informed to consent to screening. We argue that there is no evidence that this kind of screening will result in a reduction of fetal harm and there is a danger that undermining the autonomy of women and the trust relationship between women and healthcare professionals may even increase harm to future children.

In English, deictic verbs of motion, such ascomecan encode the perspective of the speaker, or another individual, such as the addressee or a narrative protagonist, at a salient reference time and location, in the form of an indexical presupposition. By contrast, Spanish has been claimed to have stricter requirements on licensing conditions forvenir(“to come”), only allowing speaker perspective. An open question is how a bilingual learner acquiring both English and Spanish reconciles these diverging language-specific restrictions. We face this question (...) head on by investigating narrative productions of young Spanish-English bilingual heritage speakers of Spanish, in comparison to English monolingual and Spanish dominant adults and children. We find that the young heritage speakers producevenirin linguistic contexts where most Spanish adult speakersdo not, but where English monolingual speakersdo, and also resemble those of young monolingual Spanish speakers of at least one other Spanish dialect, leading us to generate two mutually-exclusive hypotheses: (a) the encoding of speaker perspective in the young heritage children is cross-linguistically influenced by the more flexible and dominant language (English), resulting in a wider range of productions by these malleable young speakers than the Spanish grammar actually allows, or (b) the young Spanish speakers are exhibiting productions that are in fact licensed in the grammar, but which are pruned away in the adult productions, being supplanted by other forms as the lexicon is enriched. Given independent evidence of the heritage speakers' robust Spanish linguistic competence, we turn to systematically-collected acceptability judgments of three dialectal varieties of monolingual adult Spanish speakers of the distribution of perspective-taking verbs, to assess their competence and adjudicate between (a) and (b). We find that adultsaccept venirin contexts in which they do notproduceit, leading us to argue that (a)venirisnotobligatorily speaker-oriented in Spanish, as has been claimed, (b) adults may not producevenirin these contexts because they instead select more specific motion verbs, and (c) for heritage bilingual children, the more dominant language (English) may support the grammatically licensed but lexically-constrained productions in Spanish.

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)

Repetition dynamically shaped important modes of thought and action in early modern British and European cultures. The centrality and often problematic ambiguity of repetition as they converge in ritual, routine, and regime, however, are rarely assessed accurately because repetition is often dismissed as quaintly primitive or embarrassingly visceral. Ritual, Routine, and Regime is a collection of essays that reveals varied meanings given to and created by repetition from a range of disciplinary perspectives. The contributors reveal repetition at work in evolving (...) definitions of the self and of the emotions, in political rhetoric used to assert a nation's history, in values ascribed to musical styles, in religious verse grounded in practices of prayer, in the aesthetics created by the poetry of work and by rhyme in general, in the recreation of British classics through French translations, and in the repeated but significantly varied sculpture of the portrait bust. Edited by Lorna Clymer, Ritual, Routine, and Regime juxtaposes early modern practices with twentieth- and twenty-first century theoretical accounts of the institutions of repetition. Providing a stimulating, new perspective on early modern culture, the collection describes repetition's often peculiar demands, its surprising gratifications, and its contested interpretations.

: The Centers for Disease Control and Prevention (CDC) has recommended that HIV testing be routinely offered to certain patients in hospitals with a high prevalence of HIV infection and on all pregnant women. The CDC does not, however, offer implementation level guidelines for obtaining informed consent. We provide a moral justification for requiring informed consent for HIV testing and propose guidelines for securing such consent. In particular we argue that genuine informed consent can be secured without elaborate counseling, such (...) as that currently used at Counseling and Testing Sites, provided that sufficient written notice is given to the patients before testing and that they are specifically asked for permission.

The chapter presents the prototyping of a thinking routine designed to foster good inference habits in children ages 6 to 11. The prototyping was developed at Ninho, an educational project for children from underprivileged households in Brazil. The thinking routines by Ritchhart and colleagues (2006) served as our starting point. Following a Virtue Education (VE) approach, we supposed that the repeated application would conduce to habituation. In addition, to increase peer-to-peer interactions, the teacher applying the routines worked as (...) a facilitator in a Community of Inquiry (CI). After six months of application, the results were partially successful. We identified that the repeated exposition to the magic question “What makes you say that?” made children more aware of the evidence supporting their assumptions. Furthermore, the interactions between peers made them recognize different perspectives. However, we also identified some shortcomings. Most of them seemed to arise from cognitive biases. At the individual level, belief perseverance kept children too attached to their first assumptions. They preferred self-serving rationalizations instead of accepting a counter-argument. At the group level, we identified problems of social contagion such as information cascades. The effects of a first opinion rhetorically voiced were hard to efface. Since none of the steps on the previous routines addressed these biases, we prototyped a routine to start filling this gap. Following Critical Thinking (CT) theorists, we added a step of structured instruction concerning one specific reasoning technique - the inference to the best explanation. Moreover, the recommendation of cognitive psychologists motivated the inclusion of some extra features to avoid groupthink biases. For instance, a visual table that juxtaposes contrasting arguments should facilitate comparative evaluations. Also, a star-based evaluation scale should help different individuals to discuss their assessments based on a common ground. As described in the end, the prototype with elements from VE, CI and CT presented promising results. (shrink)

This qualitative cross-sectional survey, undertaken in the antenatal booking clinics of a hospital in central London, explores pregnant women’s responses to routine HIV testing, examines their reasons for declining or accepting the test, and assesses how far their responses fulfil standard criteria for informed consent. Of the 32 women interviewed, only 10 participants were prepared for HIV testing at their booking interview. None of the women viewed themselves as being particularly at risk for HIV infection. The minority of the participants (...) who declined testing differed from those who accepted, by interpreting test acceptance as risky behaviour, privileging the negative outcomes of HIV positivity and expressing an inability to cope with these, should they occur. Troublingly, only a minority of women had a broad understanding of the rationale for the test, and none fulfilled the standard criteria for informed consent. This study suggests that, although routine screening combined with professional recommendation may be successful in increasing uptake, this may be at the cost of eroding informed consent. Protecting third parties from a preventable disease may outweigh the moral duty of respecting autonomy, enshrined in Western bioethical tradition. Nevertheless, such a policy should be made transparent, debated in the public domain and negotiated with women seeking antenatal care. (shrink)

Lorsque l’individu de la surmodernité, placé dans un environnement dominé par le risque et entraîné dans le « grand dérangement », est soustrait à sa routine et confronté à un moment fatidique, c’est-à-dire lourd pour lui de conséquences mal maîtrisables a priori, il est appelé à passer d’un système expert à un autre système expert, ce que peut lui faciliter une réflexivité cognitive bien alimentée.When the individual of the late modernity, situated within an environment dominated by risk and swept along (...) by the « big disarrangement » is drawn from his/her routine and affronted with a fateful moment, i.e. filled for him/her with not easily controlled consequences, he/she is drawn from an expert system to another expert system, which can be made easier for him/her, thanks to a well-fed reflexivity.

An enduring ethical dispute accompanies prenatal screening and testing (PST) technologies. This ethical debate focuses on notions of reproductive choice. On one side of the dispute are those who have supported PST as a way to empower women’s reproductive choice, while on the other side are those who argue that PST, particularly when made a routine part of prenatal care, limits deliberate choice. Empirical research does not resolve this ethical debate with evidence both of women for whom PST enhances their (...) choices but also persistent evidence of recurrent problems between PST and women’s autonomous decision-making. While there have been attempts to remove challenges to reproductive choice, it has been argued that these challenges cannot be removed entirely. In this paper I provide a historical review of PST technologies’ development and in doing so provide a detailed insight into the root causes of this tension between the opposing sides of this debate. This historical account provides evidence that those who championed the early use of these technologies did so in order to achieve a number of wholly different goals other than women’s choice and empowerment. These different aims focus on scientific discovery and eugenic goals and, I argue, areirreconcilablewith women’s choice and empowerment. It thus may not be surprising that the resulting practice of PST continues to resist compatibility with women’s choice and empowerment. Ultimately, by understanding the historical foundations of PST we can more effectively assess how toreconcilewomen’s reproductive autonomy with routine prenatal screening. (shrink)

Defense of a non-psychological dynamics of demonstrative thoughts.

The motor system might well use deictic strategies when subjects learn a new task. However, its not clear that Ballard et al. show this. Multiple eye-fixations may have little to do with deixis and more to do with the unfamiliarity of the task. In any case, deixis does not entail embodiment, since a disembodied Cartesian brain could use deictic strategies.

In this paper, I explore the concept conduct of everyday life, namely routines and real life, as they are confronted with empirical observations. The observations are from a study of changes in the conduct of everyday life for individuals who attended a patient education course. The course was a part of their treatment after a hospitalisation with depression in a psychiatric ward. I use analysis of the main individual, Steven’s, conduct of everyday life and illustrate my points with models (...) of conduct of everyday life made using beads. The conceptualisation of conduct of everyday life is expanded through three points. Firstly, cyclic routines can matter and fulfill life, which can support the ongoing discussion about the concept conduct of everyday life. Secondly, I show that, from a first person perspective, what matters in conduct of everyday life is more complex than what is possible to grasp analytically through a dualistic opposition between cyclic everyday conduct and the particular meaningful conduct of everyday life. Thirdly, I expand on the notion of timeouts/breaks as solely something that lifts us out of mundane everyday life. I conclude that it makes a more comprehensive analysis to perceive all conduct of everyday life as having profound personal meaning and to analyse the individuals' concerns in relation to their social self-understanding and localisation at a certain time.

The religious justification for male circumcision proffered by Jewish and Islamic parents is frequently overlooked in current secular (medical/hygienic) discussions that (1) challenge the moral justification of this ancient practice, and (2) question the decisions of today's parents who are committed, on the basis of their religious beliefs, to continue this practice.

This special issue of Science, Technology, & Human Values contains articles concerned with ethics in and around scientific practice. These articles ask how organizational routines both produce and diffuse concerns about the risks and benefits of scientific research and products, and why context remains elusive in formal ethical analysis.

Each article describes in some way how cultural and institutional configurations shape (...) ethical thinking and the distribution of goods and harms in science. (shrink)

There is a debate over whether actions that resist devaluation are primarily habit- or goal-directed. The incentive habit account of compulsive actions has received support from behavioral paradigms and brain imaging. In addition, the self-reported Creature of Habit Scale has been proposed to capture inter-individual differences in habitual tendencies. It is subdivided into two dimensions: routine and automaticity. We first considered a French version of this questionnaire for validation, based on a sample of 386 undergraduates. The relationship between two dimensions (...) of habit and the risk of substance use disorder and impulsive personality traits was also investigated. COHS has good psychometric properties with both features of habits positively associated with an Obsessive-Compulsive Inventory score. Besides, the propensity to rely more on routines was associated with lower levels of alcohol abuse and nicotine use, suggesting that some degree of routine might act as a protective factor against substance use. In contrast, a high automaticity score was associated with an increased risk of harmful alcohol use. These results demonstrate that the COHS is a valid measure of habitual tendencies and represents a useful tool for capturing inter-individual variations in drug use problems in undergraduates.

Animal health is a key factor affecting the economic efficiency of the dairy industry. Improvements in animal health are also of relevance to society more broadly, given important implications for animal welfare, food safety and quality. Although the economic gains of best practice with regard to animal health have been well documented, many farmers are not adopting optimal herd management techniques. This paper utilises nationally representative farm-level data from Ireland for 2013 to identify drivers and barriers to the adoption of (...) best practice with regard to on-farm mastitis management. Exploratory factor analysis is used to derive measures of farmers’ attitudes towards animal health and mastitis and econometric techniques are employed to empirically assess the influence of these on the uptake of beneficial herd health management practices. A number of focus groups were also undertaken to complement the analysis. This paper concludes that farmers’ attitudes towards animal health are not a key driver in the uptake of best practice, although perceived disease risk is of relevance. A number of interesting issues arise in identifying barriers to the uptake of best practice, these include the possibility of routine inertia, i.e., farmers do not deviate from the routine developed around mastitis prevention until there is an indication of infection, as well as constraints around the availability of labour and time. Farmer behaviour with respect to mastitis management can thus be considered as reactionary as opposed to precautionary. This research highlights the valuable role of the extension agent but concludes that engagement around knowledge transfer and technology adoption is particularly complex. (shrink)

I offer a critique of how we have gotten to the point of considering xenografts into humans through a kind of moral failure to generate an efficient system of organ harvesting from human cadavers. I consider several proposals for increasing the supply of transplantable human organs, including one recently proposed in detail by James Lindemann Nelson of the Hastings Center for routine retrieval with an opt-out option.
