In this paper, I will reread the history of molecular genetics from a psychoanalytical angle, analysing it as a case history. Building on the developmental theories of Freud and his followers, I will distinguish four stages, namely: (1) oedipal childhood, notably the epoch of model building (1943–1953); (2) the latency period, with a focus on the development of basic skills (1953–1989); (3) adolescence, exemplified by the Human Genome Project, with its fierce conflicts, great expectations and grandiose claims (1989–2003) and (4) (...) adulthood (2003–present) during which revolutionary research areas such as molecular biology and genomics have achieved a certain level of normalcy—have evolved into a normal science. I will indicate how a psychoanalytical assessment conducted in this manner may help us to interpret and address some of the key normative issues that have been raised with regard to molecular genetics over the years, such as ‘relevance’, ‘responsible innovation’ and ‘promise management’.

What role does the wild duck play in Ibsen's famous drama? I argue that, besides mirroring the fate of the human cast members, the duck is acting as animal subject in a quasi-experiment, conducted in a private setting. Analysed from this perspective, the play allows us to discern the epistemological and ethical dimensions of the new scientific animal practice emerging precesely at that time. Ibsen's play stages the clash between a scientific and a romantic understanding of animals that still constitutes (...) the backdrop of most contemporary debates over animals in research. Whereas the scientific understanding reduces the animal's behaviour, as well as its environment, to discrete and modifiable elements, the romantic view regards animals as being at one with their natural surroundings.

Friedrich Engels’ dialectical assessment of modern science resulted from his fascination with the natural sciences in combination with his resurging interest in the work of “old Hegel.” Engels became especially interested in what he saw as the molecular essence of life, namely proteins or, more specifically, albumin, seeing life as the mode of existence of these enigmatic substances. Hegelian dialectics is crucial for a dialectical materialist understanding of contemporary technoscience. The dialectical materialist understanding of technoscience as a research practice builds (...) on Engels, but also on later authors who were inspired by his writings, e.g., life scientists such as Haldane and Bernal. Considering the criticism raised against Engels’ dialectics by 20th-century Marxists, a dialectical diagnostic of contemporary technoscience can be achieved, which shifts the focus from artificial albumin as “living matter” to contemporary research on synthetic cells.

This paper analyses the technoscientific objective of building a synthetic cell from a Jungian perspective. After decades of fragmentation and specialisation, the synthetic cell symbolises a turn towards restored wholeness, both at the object pole and at the subject pole. From a Jungian perspective, it is no coincidence that visual representations of synthetic cells often reflect an archetypal, mandala-like structure. As a symbol of restored unity, the synthetic cell mandala compensates for technoscientific fragmentation via active imagination, providing a visual aid (...) for the technoscientific turn towards reintegration. Although the biotechnological desire to reconstruct life in vitro has been compared to alchemy before, a Jungian analysis allows us to make this comparison more specific and precise. The problem of archetypal images, however, is that alluring prospects of reintegration may underestimate and obfuscate the deficiencies and tensions at work in the current situation. As a projection of a future wholeness, it fosters optimism, but may also function as a misleading façade, covering up collisions and complexities. This can be averted by the conscious employment of the mandala as a symbolic scaffold fostering processes of individuation and working through. (shrink)

The Centre for Society and Genomics (CSG) was established in 2004, funded by NGI (the Netherlands Genomics Initiative). Funding was continued in 2008. This report summarises the basic outcomes of almost a decade of interactive societal research, in close collaboration with the other centres of the NGI network. There are two reasons for presenting these results. First of all, at the end of this year, the CSG Next programme (2008-2013), encompassing more than 50 research projects conducted at 10 Dutch universities, (...) will be completed. Moreover, we are currently preparing ourselves for the years to come. The network of principal investigators, together with the research communities they represent and the societal and international networks they are involved in, have agreed to continue to work together, on the basis of mutual learning, transdisciplinary collaboration and collegial support. Notably, we offer our networks, experiences and expertise to help prepare the ground for promoting Responsible Research and Innovation (RRI) in the context of Horizon2020, together with our European colleagues. This report summarises what our type of research can achieve and how we want to continue our activities in the future. After a concise sketch of the life sciences landscape as it has evolved during the past seven decades or so, we explain how CSG came about and what kind of approach we have developed. Subsequently, we list our main results, notably in the form of project vignettes, so as to make the harvest of the CSG Next programme as tangible and concrete as possible. Finally, we explain how we see our role in the future. As is already indicated by the title: this is not merely a retrospective summary of our results (CSG harvest), but an invitation to readers (from academia, industry, policy and civil society) to reassemble and to optimally prepare ourselves for things to come, by strengthening and broadening our collaborative efforts, building on what we have achieved so far.

This paper subjects Dan Brown’s most recent novel Origin to a philosophical reading. Origin is regarded as a literary window into contemporary technoscience, inviting us to explore its transformative momentum and disruptive impact, focusing on the cultural significance of artificial intelligence and computer science: on the way in which established world-views are challenged by the incessant wave of scientific discoveries made possible by super-computation. While initially focusing on the tension between science and religion, the novel’s attention gradually shifts to the (...) increased dependence of human beings on smart technologies and artificial intelligence. Origin’s message, I will argue, reverberates with Oswald Spengler’s The Decline of the West, which aims to outline a morphology of world civilizations. Although the novel starts with a series of oppositions, most notably between religion and science, the eventual tendency is towards convergence, synthesis and sublation, exemplified by Sagrada Família as a monumental symptom of this transition. Three instances of convergence will be highlighted, namely the convergence between science and religion, between humanity and technology and between the natural sciences and the humanities. (shrink)

This paper addresses the cultural impact of genomics and the Human Genome Project on human self-understanding. Notably, it addresses the claim made by Francis Collins that the genome is the language of God and the claim made by Max Delbrück that Aristotle must be credited with having predicted DNA as the soul that organises bio-matter. From a continental philosophical perspective I will argue that human existence results from a dialectical interaction between two types of texts: the language of molecular biology (...) and the language of civilisation; the language of the genome and the language of our socio-cultural, symbolic ambiance. Whereas the former ultimately builds on the alphabets of genes and nucleotides, the latter is informed by primordial texts such as the Bible and the Quran. In applied bioethics deliberations on genomics, science is easily framed as liberating and progressive, religious world-views as conservative an... (shrink)

Much has been said about the need for improving the current definitions of scientific authorship, but an aspect that is often overlooked is how to formulate and communicate these definitions to ensure that they are comprehensible and useful for researchers, notably researchers active in international research consortia. In light of a rapid increase in international collaborations within natural sciences, this article uses authorship of this branch of sciences as an example and provides suggestions to improve the comprehensibility of the definitions (...) of authorship in natural sciences. It assesses whether the definition of authorship provided by the European Code of Conduct for Research Integrity can deal with current issues and problems of scientific authorship. Notably, problems that are experienced in project groups with researchers coming from multiple countries. Using theories developed by Jürgen Habermas and Robert Merton, a normative framework is developed to articulate ethical authorship in natural sciences. Accordingly, enriching the current definition of authorship with normative elements and using discipline-specific metaphors to communicate them are introduced as possible ways of improving the comprehensibility of the definition of authorship in international environments. Finally, this article provides a proposal to be considered in the future revisions of the European Code of Conduct for Research Integrity. (shrink)

Metaphors for describing the introduction, impacts, and management of non-native species are numerous and often quite outspoken. Policy-makers have adopted increasingly disputed metaphorical terms from scientific discourse. We performed a critical analysis of the use of strong metaphors in reporting scientific findings to policy-makers. Our analysis shows that perceptions of harm, invasiveness or nativeness are dynamic and inevitably display multiple narratives in science, policy or management. Improving our awareness of multiple expert and stakeholder narratives that exist in the context of (...) non-native species management, as well as metaphorical alternatives, is critical. (shrink)

Precision Medicine is driven by the idea that the rapidly increasing range of relatively cheap and efficient self-tracking devices make it feasible to collect multiple kinds of phenotypic data. Advocates of N = 1 research emphasize the countless opportunities personal data provide for optimizing individual health. At the same time, using biomarker data for lifestyle interventions has shown to entail complex challenges. In this paper, we argue that researchers in the field of precision medicine need to address the performative dimension (...) of collecting data. We propose the fun-house mirror as a metaphor for the use of personal health data; each health data source yields a particular type of image that can be regarded as a ‘data mirror’ that is by definition specific and skewed. This requires competence on the part of individuals to adequately interpret the images thus provided. (shrink)

Review of collection of papers, primarily concerning the Phillipines, edited by H.T. Engelhardt and introduced by E. Pellegrino.

En este texto se analiza cómo el filósofo español exiliado en México, José Gaos (1900- 1969), considera que la filosofía hispanoamericana, e incluso las propias tierras americanas, son lugares de una “utopía – aunque no ucronía-, debido a que tanto las tradiciones trascendente-religiosas como inmanente-filosóficas europeas han convertido a América, y como resultado final de una determinada filosofía de la historia, en lugar ideal del futuro del pensamiento filosófico –y, en última instancia, del hombre contemporáneo.

• Aggregates of previously isolated cells of Hydra are capable, under suitable solvant conditions, of regeneration forming complete animals. In a first stage, ecto- and endodermal cells sort out, producing the bilayered hollow structure characteristic of Hydra tissue; thereafter, heads are formed (even if the original cell preparation contained no head cells), eventually leading to the separation of normal animals with head, body column and foot. Hydra appears to be the highest type of organism that allows for regeneration of the (...) entire structure from random cell aggregates. The system is particularly useful for studying cell interactions, tissue polarity, pattern formation, and cell differentiation. (shrink)

In various documents the view emerges that contemporary biotechnosciences are currently experiencing a scientific revolution: a massive increase of pace, scale and scope. A significant part of the research endeavours involved in this scientific upheaval is devoted to understanding and, if possible, ameliorating humankind: from our genomes up to our bodies and brains. New developments in contemporary technosciences, such as synthetic biology and other genomics and “post-genomics” fields, tend to blur the distinctions between prevention, therapy and enhancement. An important dimension (...) of this development is “biomimesis”: i.e. the tendency of novel technologies and materials to mimic or plagiarize nature on a molecular and microscopic level in order to optimise prospects for the embedding of technological artefacts in natural systems such as human bodies and brains. In this paper, these developments are read and assessed from a psychoanalytical perspective. Three key concepts from psychoanalysis are used to come to terms with what is happening in research laboratories today. After assessing the general profile of the current revolution in this manner, I will focus on a particular case study, a line of research that may serve as exemplification of the vicissitudes of contemporary technosciences, namely viral biomaterials. Viral life forms can be genetically modified (their genomes can be rewritten) in such a manner that they may be inserted in human bodies in order to produce substances at specific sites such as hormones (testosterone), neurotransmitters (dopamine), enzymes (insulin) or bone and muscle tissue. Notably, certain target groups such as top athletes, soldiers or patients suffering from degenerative diseases may become the pioneers serving as research subjects for novel applications. The same technologies can be used for various purposes ranging from therapy up to prevention and enhancement. (shrink)

Animal ethicists have recently debated the ethical questions raised by disenhancing animals to improve their welfare. Here, we focus on the particular case of breeding hens for commercial egg-laying systems to become blind, in order to benefit their welfare. Many people find breeding blind hens intuitively repellent, yet ‘welfare-only’ positions appear to be committed to endorsing this possibility if it produces welfare gains. We call this the ‘Blind Hens’ Challenge’. In this paper, we argue that there are both empirical and (...) theoretical reasons why even those adopting ‘welfare-only’ views should be concerned about breeding blind hens. But we also argue that alternative views, which (for example) claim that it is important to respect the telos or rights of an animal, do not offer a more convincing solution to questions raised by the possibility of disenhancing animals for their own benefit.

I argue, first, that the deprived individuals whose predicaments Nussbaum cites as examples of "adaptive preference" do not in fact prefer the conditions of their lives to what we should regard as more desirable alternatives, indeed that we believe they are badly off precisely because they are not living the lives they would prefer to live if they had other options and were aware of them. Secondly, I argue that even where individuals in deprived circumstances acquire tastes for conditions that (...) we regard as bad, they are typically better off having their acquired preferences satisfied. If they are badly off it is because they cannot get what we and they, would regard as more desirable alternatives. Preference utilitarianism explains why individuals in such circumstances are badly off whether they have adapted to their deprived circumstances or not. Even if they prefer the conditions of their lives to all other available alternatives, most would prefer alternatives that are not available to them which would, on the preferentist account, make them better off. And that, on the preferentist account, is the basis for a radical critique of unjust institutions that limit people's options and prevent them from getting what they want. (shrink)

It is proposed that our memory is made up of individual, unconnected Records, to each of which is attached a Heading. Retrieval of a Record can only be accomplished by addressing the attached Heading, the contents of which cannot itself be retrieved. Each Heading is made up of a mixture of content in more or less literal form and context, the latter including specification of environment and of internal states (e.g. drug states and mood). This view of memory allows an (...) easy account of a number of natural memory phenomena as well as a variety of laboratory findings such as the differences between recall and recognition. The theory further proposes that Headed Records can neither be deleted nor modified. Data apparently against such a hypothesis can be accounted for in terms of the retrieval process. (shrink)

The doctrine that Christ is really present in the Eucharist appears to entail that Christ's body is not only multiply located but present in different ways at different locations. Moreover, the doctrine poses an even more difficult meta-question: what makes a theological explanation of the Eucharist a ‘real presence’ account? Aquinas's defence of transubstantiation, perhaps the paradigmatic account, invokes Aristotelian metaphysics and the machinery of Scholastic philosophy. My aim is not to produce a ‘rational reconstruction’ of his analysis but rather (...) to suggest a metaphysically innocent alternative that will ‘save the phenomena’ of religious belief and practice.Send article to KindleTo send this article to your Kindle, first ensure no-reply@cambridge.org is added to your Approved Personal Document E-mail List under your Personal Document Settings on the Manage Your Content and Devices page of your Amazon account.

Initial responses to questionnaires used to assess participants' understanding of informed consent for malaria vaccine trials conducted in the United States and Mali were tallied. Total scores were analyzed by age, sex, literacy (if known), and location. Ninety-two percent (92%) of answers by United States participants and 85% of answers by Malian participants were correct. Questions more likely to be answered incorrectly in Mali related to risk, and to the type of vaccine. For adult participants, independent predictors of higher scores (...) were younger age and female sex in the United States, and male sex in Mali. Scores in the United States were higher than in Mali (P = 0.005). Despite this difference participants at both sites were well informed overall. Although interpretation must be qualified because questionnaires were not intended as research tools and were not standardized among sites, these results do not support concerns about systematic low understanding among research participants in developing versus developed countries.

Presence as ordinarily understood requires spatio-temporal proximity. If however Christ’s presence in the Eucharist is understood in this way it would take a miracle to secure multiple location and an additional miracle to cover it up so that the presence of Christ where the Eucharist was celebrated made no empirical difference. And, while multiple location is logically possible, such metaphysical miracles—miracles of distinction without difference, which have no empirical import—are problematic. I propose an account of Eucharist according to which Christ (...) is indeed really and objectively present in the religiously required sense, without benefit of metaphysical miracles. According to the proposed account, which draws upon Searle’s discussion of “social ontology” in The Construction of Social Reality and The Making of the Social World, the presence of Christ in the Eucharist is an institutional fact. I argue that such an account satisfies the requirements for a real presence doctrine. (shrink)

Context: Many recent research areas such as human cognition and quantum physics call the observer-independence of traditional science into question. Also, there is a growing need for self-reflexivity in science, i.e., a science that reflects on its own outcomes and products. Problem: We introduce the concept of second-order science that is based on the operation of re-entry. Our goal is to provide an overview of this largely unexplored science domain and of potential approaches in second-order fields. Method: We provide the (...) necessary conceptual groundwork for explorations in second-order science, in which we discuss the differences between first- and second-order science and where we present a roadmap for second-order science. The article operates mainly with conceptual differentiations such as the separation between three seemingly identical concepts such as Science II, Science 2.0 and second-order science. Results: Compared with first-order science, the potential of second-order science lies in 1. higher levels of novelty and innovations, 2. higher levels of robustness and 3. wider integration as well as higher generality. As first-order science advances, second-order science, with re-entry as its basic operation, provides three vital functions for first-order science, namely a rich source of novelty and innovation, the necessary quality control and greater integration and generality. Implications: Second-order science should be viewed as a major expansion of traditional scientific fields and as a scientific breakthrough towards a new wave of innovative research. Constructivist content: Second-order science has strong ties with radical constructivism, which can be qualified as the most important root/origin of second-order science. Moreover, it will be argued that a new form of cybernetics is needed to cope with the new problems and challenges of second-order science. (shrink)

In the unfolding debate on the prospects, challenges and viability of the imminent transition towards a ‘Bio-Based Society’ or ‘Bio-based Economy’—i.e. the replacement of fossil fuels by biomass as a basic resource for the production of energy, materials and food, ‘big’ concepts tend to play an important role, such as, for instance, ‘sustainability’, ‘global justice’ and ‘naturalness’. The latter concept is, perhaps, the most challenging and intriguing one. In public debates concerning biotechnological interactions with the natural environment, the use of (...) terms such as ‘nature’ and ‘naturalness’ is both inevitable and hazardous . Indeed, various conflicting interpretations of naturalness play a role on both sides of the current debate. This paper aims to analyse and critically assess the role of ‘nature-speak’ in the BBS transition. We will begin with a concise overview of the vicissitudes of the nature-concept so far, focussing on how modern science and technology have challenged and affected our understanding of what nature is. Subsequently, we describe how ‘naturalness’ functions in the unfolding BBS debate. Finally, we will focus on a particular case study, namely the production of rubber with the help of natural latex coming from dandelion plants rather than from rubber trees. On the one hand, this is presented as a more natural and nature-friendly way of producing rubber. On the other hand, it is a sophisticated process, involving high technology and primarily focussed on competitiveness on the global market. To what extent or in what sense can dandelion latex be regarded as more natural? And what can we learn from this case study when it comes to addressing naturalness in the broader conceptual and bio-political arena? (shrink)

In various writings Michel Foucault has shown how, in the beginning of the 19th century, in settings such as army barracks, psychiatric hospitals and penitentiary institutions, the modern human sciences were ‹born› as an ensemble of disciplines (medical biology, psychiatry, psychology, criminology, and the like) From the beginning, the nature-nurture de- bate has been one of its key disputes. Are human individuals malleable by environmental factors (such as psychiatric treatments or disciplinary regimes), or do they rather display inborn predispositions for (...) delin- quency and other forms of antisocial behaviour? In the current era of genetic testing, in behavioural genomics and neuroscience, this issue is as controversial and topical as ever. Büchner’s unfinished drama Woyzeck (written in 1836) is a remarkable anticipation of this debate, staging the birth of the human individual as a research subject. It is the story of a destitute soldier who, according to his superiors, displays er- rant behaviour and is therefore recruited to serve as a research subject in an experiment. His army physician turns him into a ‹case›, which can be meticulously monitored and studied so as to record the genesis of a crime. In this paper, Büchner’s unsettling play is analysed in detail as one of the great anticipatory literary documents of the 19th century, ex- ploring the idea of predictive psychiatry and the quest for genetic pre- dispositions: a primal scene as it were of the nature-nurture debate as it unfolds from predictive criminology up to behavioural genomics.

The scientific community, we hold, often provides society with knowledge—that the HIV virus causes AIDS, that anthropogenic climate change is underway, that the MMR vaccine is safe. Some deny that we have this knowledge, however, and work to undermine it in others. It has been common to refer to such agents as “denialists”. At first glance, then, denialism appears to be a form of skepticism. But while we know that various denialist strategies for suppressing belief are generally effective, little is (...) known about which strategies are most effective. We see this as an important first step toward their remediation. This paper leverages the approximate comparison to various forms of philosophical skepticism to design an experimental test of the efficacy of four broad strategies of denial at suppressing belief in specific scientific claims. Our results suggest that assertive strategies are more effective at suppressing belief than questioning strategies. (shrink)

Modifying the descriptive and theoretical generalizations of Relativized Minimality, we argue that a significant subset of weak island violations arise when an extracted phrase should scope over some intervener but is unable to. Harmless interveners seem harmless because they can support an alternative reading. This paper focuses on why certain wh-phrases are poor wide scope takers, and offers an algebraic perspective on scope interaction. Each scopal element SE is associated with certain operations (e.g., not with complements). When a wh-phrase scopes (...) over some SE, the operations associated with that SE are performed in its denotation domain. The requisite operations may or may not be available in a domain, however. We present an empirical analysis of a variety of wh-phrases. It is argued that the wh-phrases that escape all weak islands (i.e., can scope over any intervener) are those that range over individuals, the reason being that all Boolean operations are defined for their domain. Collectives, manners, amounts, numbers, etc. all denote in domains with fewer operations and are thus selectively sensitive to scopal interveners—a “semantic relativized minimality effect”. (shrink)

The results are interpreted in terms of a deficit in initial rule learning and subsequent generalization of these rules to new stimuli. Negative feedback is adequately processed at a neural level but this information is not used to improve behaviour on subsequent trials. As learning is degraded, the process of error detection at the moment of the actual response is diminished. Therefore, the current study demonstrates that disturbed error-monitoring processes play a central role in the often reported learning deficits in (...) individuals with PP. (shrink)

Objective: There are benefits and risks of giving patients more granular control of their personal health information in electronic health record (EHR) systems. When designing EHR systems and policies, informaticists and system developers must balance these benefits and risks. Ethical considerations should be an explicit part of this balancing. Our objective was to develop a structured ethics framework to accomplish this. -/- Methods: We reviewed existing literature on the ethical and policy issues, developed an ethics framework called a “Points to (...) Consider” (P2C) document, and convened a national expert panel to review and critique the P2C. -/- Results: We developed the P2C to aid informaticists designing an advanced query tool for an electronic health record (EHR) system in Indianapolis. The P2C consists of six questions (“Points”) that frame important ethical issues, apply accepted principles of bioethics and Fair Information Practices, comment on how questions might be answered, and address implications for patient care. -/- Discussion: The P2C is intended to clarify whatis at stake when designers try to accommodate potentially competing ethical commitments and logistical realities. The P2C was developed to guide informaticists who were designing a query tool in an existing EHR that would permit patient granular control. While consideration of ethical issues is coming to the forefront of medical informatics design and development practices, more reflection is needed to facilitate optimal collaboration between designers and ethicists. This report contributes to that discussion. (shrink)

Throughout the biological and biomedical sciences there is a growing need for, prescriptive ‘minimum information’ (MI) checklists specifying the key information to include when reporting experimental results are beginning to find favor with experimentalists, analysts, publishers and funders alike. Such checklists aim to ensure that methods, data, analyses and results are described to a level sufficient to support the unambiguous interpretation, sophisticated search, reanalysis and experimental corroboration and reuse of data sets, facilitating the extraction of maximum value from data sets (...) them. However, such ‘minimum information’ MI checklists are usually developed independently by groups working within representatives of particular biologically- or technologically-delineated domains. Consequently, an overview of the full range of checklists can be difficult to establish without intensive searching, and even tracking thetheir individual evolution of single checklists may be a non-trivial exercise. Checklists are also inevitably partially redundant when measured one against another, and where they overlap is far from straightforward. Furthermore, conflicts in scope and arbitrary decisions on wording and sub-structuring make integration difficult. This presents inhibit their use in combination. Overall, these issues present significant difficulties for the users of checklists, especially those in areas such as systems biology, who routinely combine information from multiple biological domains and technology platforms. To address all of the above, we present MIBBI (Minimum Information for Biological and Biomedical Investigations); a web-based communal resource for such checklists, designed to act as a ‘one-stop shop’ for those exploring the range of extant checklist projects, and to foster collaborative, integrative development and ultimately promote gradual integration of checklists.

Upshot: In our response we focus on five questions that point to important common themes in the commentaries: why start in wicked problems, what kind of system is a scientific perspective, what is the nature of second-order research processes, what does this mean for understanding interdisciplinary work, and how may polyocular research help make real-world decisions.

Science communication via testimony requires a certain level of trust. But in the context of ideologically-entangled scientific issues, trust is in short supply—particularly when the issues are politically ‘entangled’. In such cases, cultural values are better predictors than scientific literacy for whether agents trust the publicly-directed claims of the scientific community. In this paper, we argue that a common way of thinking about scientific literacy—as knowledge of particular scientific facts or concepts—ought to give way to a second-order understanding of science (...) as a process as a more important notion for the public’s trust of science.

Recent increases in the volume and diversity of life science data and information and an increasing emphasis on data sharing and interoperability have resulted in the creation of a large number of biological ontologies, including the Cell Ontology (CL), designed to provide a standardized representation of cell types for data annotation. Ontologies have been shown to have significant benefits for computational analyses of large data sets and for automated reasoning applications, leading to organized attempts to improve the structure and formal (...) rigor of ontologies to better support computation. Currently, the CL employs multiple is_a relations, defining cell types in terms of histological, functional, and lineage properties, and the majority of definitions are written with sufficient generality to hold across multiple species. This approach limits the CL's utility for computation and for cross-species data integration. Results: To enhance the CL's utility for computational analyses, we developed a method for the ontological representation of cells and applied this method to develop a dendritic cell ontology (DC-CL). DC-CL subtypes are delineated on the basis of surface protein expression, systematically including both species-general and species-specific types and optimizing DC-CL for the analysis of flow cytometry data. We avoid multiple uses of is_a by linking DC-CL terms to terms in other ontologies via additional, formally defined relations such as has_function. This approach brings benefits in the form of increased accuracy, support for reasoning, and interoperability with other ontology resources. Accordingly, we propose our method as a general strategy for the ontological representation of cells. DC-CL is available from http://www.obofoundry.org. (shrink)

Barry Smith, “Toward a Realistic Science of Environments”, Ecological Psychology, 2009, 21 (2), April-June, 121-130. Abstract: The perceptual psychologist J. J. Gibson embraces a radically externalistic view of mind and action. We have, for Gibson, not a Cartesian mind or soul, with its interior theater of contents and the consequent problem of explaining how this mind or soul and its psychological environment can succeed in grasping physical objects external to itself. Rather, we have a perceiving, acting organism, whose perceptions and actions are always already tuned to the parts and moments, the things and surfaces, of its external environment. We describe how on this basis Gibson sought to develop a realist science of environments which will be ‘consistent with physics, mechanics, optics, acoustics, and chemistry’. (shrink)

The Twin Earth thought experiment invites us to consider a liquid that has all of the superficial properties associated with water (clear, potable, etc.) but has entirely different deeper causal properties (composed of “XYZ” rather than of H2O). Although this thought experiment was originally introduced to illuminate questions in the theory of reference, it has also played a crucial role in empirically informed debates within the philosophy of psychology about people’s ordinary natural kind concepts. Those debates have sought to accommodate (...) an apparent fact about ordinary people’s judgments: Intuitively, the Twin Earth liquid is not water. We present results from four experiments showing that people do not, in fact, have this intuition. Instead, people tend to have the intuition that there is a sense in which the liquid is not water but also a sense in which it is water. We explore the implications of this finding for debates about theories of natural kind concepts, arguing that it supports views positing two distinct criteria for membership in natural kind categories – one based on deeper causal properties, the other based on superficial, observable properties.

We present a deductive theory of space-time which is realistic, objective, and relational. It is realistic because it assumes the existence of physical things endowed with concrete properties. It is objective because it can be formulated without any reference to cognoscent subjects or sensorial fields. Finally, it is relational because it assumes that space-time is not a thing but a complex of relations among things. In this way, the original program of Leibniz is consummated, in the sense that space is (...) ultimately an order of coexistents, and time is an order of succesives. In this context, we show that the metric and topological properties of Minkowskian space-time are reduced to relational properties of concrete things. We also sketch how our theory can be extended to encompass a Riemannian space-time. (shrink)

The biological sciences study (bio)complex living systems. Research directed at the mechanistic explanation of the "live" state truly requires a pluralist research program, i.e. BioComplexity research. The program should apply multiple intra-level and inter-level theories and methodologies. We substantiate this thesis with analysis of BioComplexity: metabolic and modular control analysis of metabolic pathways, emergence of oscillations, and the analysis of the functioning of glycolysis.

We present an axiomatization of non-relativistic Quantum Mechanics for a system with an arbitrary number of components. The interpretation of our system of axioms is realistic and objective. The EPR paradox and its relation with realism is discussed in this framework. It is shown that there is no contradiction between realism and recent experimental results.

This chapter describes the potential far‐reaching consequences of contemplative higher education for the fields of science and medicine.

In the previous article the hermeneutical approach to ethics was outlined. In my presentation, I would like to illustrate further the methodological consequences of this approach by using two points in contemporary applied ethics. The question is: to what extent is the hermeneutical approach casuistically applicable. We start with the presupposition that the hermeneutical approach does not offer answers to the question of current applied ethics — namely, to the question of what is or is not acceptable in a particular (...) problem situation — but rather, intends to clarify our moral, i.e. normative, response to problem situations. It tries to offer a precise articulation of the normative components of a successful moral decision, without presuming its detailed result. Hermeneutical ethics harks back to conceptual possibilities from the philosophical tradition to clarify the fundamental problem posed by current moral casuistry, and this for two reasons. The first is the idea that these traditional concepts are still at work in our experience and speech, such that, in taking up the tradition, the structure of our present experience is highlighted. The second is the idea that our present experience has moved away from this tradition on certain important points, such that a confrontation with these other possibilities can reveal the recent and relative character of what seems self-evident. To start with, I would like to examine the recent discussions in the media on postmenopausal pregnancy, in particular the argument that a pregnancy resulting from a medical treatment of these ‘older mothers’ is unnatural. Appealing to nature has come into discredit in ethics and in public discussions. Yet, I will defend the position that the notion of naturalness is still part of our moral experience. In other words, when we abandon any appeal to the moral significance of our biological nature, we are no longer able to express essential aspects of our moral experience. This, however, does not deny that the moral meaning of nature needs to be rethought and more accurately articulated; the appeal to nature is not obvious. At the end of my presentation, I will show that an appeal to nature also has a role to play in the recent discussions on cloning human embryos. (shrink)

This monograph contributes to the scientific misconduct debate from an oblique perspective, by analysing seven novels devoted to this issue, namely: Arrowsmith by Sinclair Lewis (1925), The affair by C.P. Snow (1960), Cantor’s Dilemma by Carl Djerassi (1989), Perlmann’s Silence by Pascal Mercier (1995), Intuition by Allegra Goodman (2006), Solar by Ian McEwan (2010) and Derailment by Diederik Stapel (2012). Scientific misconduct, i.e. fabrication, falsification, plagiarism, but also other questionable research practices, have become a focus of concern for academic communities (...) worldwide, but also for managers, funders and publishers of research. The aforementioned novels offer intriguing windows into integrity challenges emerging in contemporary research practices. They are analysed from a continental philosophical perspective, providing a stage where various voices, positions and modes of discourse are mutually exposed to one another, so that they critically address and question one another. They force us to start from the admission that we do not really know what misconduct is. Subsequently, by providing case histories of misconduct, they address integrity challenges not only in terms of individual deviance but also in terms of systemic crisis, due to current transformations in the ways in which knowledge is produced. Rather than functioning as moral vignettes, the author argues that misconduct novels challenge us to reconsider some of the basic conceptual building blocks of integrity discourse. (shrink)

This essay considers how scholarly approaches to the development of molecular biology have too often narrowed the historical aperture to genes, overlooking the ways in which other objects and processes contributed to the molecularization of life. From structural and dynamic studies of biomolecules to cellular membranes and organelles to metabolism and nutrition, new work by historians, philosophers, and STS scholars of the life sciences has revitalized older issues, such as the relationship of life to matter, or of physicochemical inquiries to (...) biology. This scholarship points to a novel molecular vista that opens up a pluralist view of molecularizations in the twentieth century and considers their relevance to current science. (shrink)

Intra-molecular connectivity (that is, chemical structure) does not emerge from computations based on fundamental quantum-mechanical principles. In order to compute molecular electronic energies (of C 3 H 4 hydrocarbons, for instance) quantum chemists must insert intra-molecular connectivity “by hand.” Some take this as an indication that chemistry cannot be reduced to physics: others consider it as evidence that quantum chemistry needs new logical foundations. Such discussions are generally synchronic rather than diachronic —that is, they neglect ‘historical’ aspects. However, systems of (...) interest to chemists generally are metastable . In many cases chemical systems of a given elemental composition may exist in any one of several different metastable states depending on the history of the system. Molecular structure generally depends on contingent historical circumstances of synthesis and separation, rather than solely or mainly on relative energies of alternative stable states, those energies in turn determined by relationships among components. Chemical structure is usually ‘kinetically-determined’ rather than ‘thermodynamically-determined.’ For instance, cyclical hydrocarbon ring-systems (as in cyclopropene) are produced only in special circumstances. Adequate theoretical treatments must take account of the persistent effects of such contingent historical events whenever they are relevant—as they generally are in chemistry. (shrink)

O presente trabalho trata da definição de fenômenos naturais. tais como o trovão que é usada como paradigma na definição das substâncias perceptíveis em Metafísica, Z17. Procura-se mostrar como a definição do trovão implica necessariamente uma referência à substância, assim como a definição das substâncias perceptíveis parte necessariamente de um acidente, que justamente funciona como matéria. Entende-se assim trazer à tona algumas questões embaraçosas para Aristóteles, que dizem respeito ao “hiato” existente entre percepção e intelecção e ao caráter não assertivo (...) da “predicação da forma".

Women in the labor force are at a disadvantage not only because of continuing discrimination in hiring and promotion, but because of factors extrinsic to the labor market hence adjusting conditions within the labor market will not completely eliminate women's disadvantage. Because, unlike most men, most women do not have spouses to take on the major responsibility of running their homes and caring for their children, the costs of working outside the home, particularly in a professional or managerial capacity, are (...) greater for women than they are for men. Thus, even if ongoing discrimination in the labor market were eliminated, through affirmative action policies or other such remedies, women would still be as a disadvantage relative to men.For women, the costs and benefits of behaving like men are different than they are for their male counterparts. To the extent that the costs and benefits of various policies of action are not the same for women as they are for men, men and women are not equal, therefore, arguably, it is not fair to treat them equally.

When the Human Genome Project (HGP) was launched, our genome was presented as our ‘blueprint’, a metaphor reflecting a genetic deterministic epistemology. Eventually, however, the HGP undermined rather than strengthened the understanding of genomes as blueprints and of genes as ultimate causal units. A symbolical turning point was the discovery that the human genome only contains 22,500 genes. Initially, this was seen as a narcissistic offence. Gradually, however, it strengthened the shift from traditional genetics and biotechnology (i.e., gene-oriented approaches) to (...) genomics, i.e. genome-oriented or systems approaches, emphasizing complexity. The 20th century can be regarded as the century of biotechnology and of the gene. Its history demonstrated that the will to know (notably: to know ourselves) has never been a disinterested affair: it is driven by a will to improve (notably: to improve ourselves). In this article it is claimed that, as genomics takes us beyond a genetic deterministic understanding of life, this must have consequences for societal research and debate as well. Policies for self-improvement will increasingly rely on the use of complex interpretation. Therefore, the emphasis must shift from issues such as genetic manipulation and human enhancement to issues involved in governance of novel forms of information. (shrink)

The paper attempts to set a guideline to contemporary common morality debate. The author points out what he sees as two common problems that occur in the field of comparative cultural studies related to a common morality debate. The first problem is that the advocates and opponents of common morality, consciously or unconsciously, define the moral terms in question in a way that their respective meanings would naturally lead to the outcomes that each party desires. The second problem is that (...) the examples each party chooses as the empirical evidences may not be as simple and clear-cut as the researchers think they are, mainly because the situational contexts where the examples are located between two different cultures vastly differ. To prevent these mistakes, the author emphasizes that we should pay attention to a subtle distinction between "thick" and "thin" construed from the levels of "theoretical status" and of "material content". With the conceptual distinctions in mind, the author shows how different cultures (i.e., Western individualist society and East Asian neo-Confucian society) see the moral principles like autonomy and beneficence in different lexical orders.

RELAÇÃO E EFEITOS BIOQUÍMICO-NUTRICIONAIS SOBRE A INVOLUÇÃO UTERINA RETARDADA EM VACAS -/- Emanuel Isaque Cordeiro da Silva Departamento de Agropecuária – IFPE Campus Belo Jardim emanuel.isaque@ufrpe.br ou eics@discente.ifpe.edu.br WhatsApp: (82)98143-8399 -/- 2. INVOLUÇÃO UTERINA RETARDADA -/- A involução uterina retardada é uma desordem reprodutiva parcialmente ocasionada por problemas nutricionais. Terminados os mecanismos do parto, os órgãos genitais da fêmea sofrerá alterações em seu tamanho, peso e forma, eles reduzem de tamanho até sua normalização, esse processo é conhecido como involução uterina (...) (LANDAETA-HERNÁNDEZ, et al. 2004); a sua duração pode variar entre quatro a oito semanas, embora idealmente deva ser atingida aos 30 dias, é mais rápida em vacas de primeiro parto, bem como em vacas que amamentam os seus bezerros e pode ser retardada em vacas que tiveram problemas nutricionais (mal alimentadas ou até desnutridas), partos gêmeos, distorcias e retenção placentária. A recuperação do útero pós-parto ou involução uterina depende de contrações miometriais, eliminação da possível infecção bacteriana e regeneração do endométrio. A regeneração como tal, é denominada involução microscópica e usualmente segue à involução macroscópica ou de redução de peso e tamanho. Esta última pode levar entre 2 a 4 semanas e a primeira, entre 4 a 6 semanas (FRAZER, 2005; GORDON, 1996). A eliminação dos loquios e a redução do tamanho uterino são causadas por contrações miometriais, devidas inicialmente à presença de estrogênio durante o parto e posteriormente à secreção sustentada de prostaglandinas após o parto, as quais aumentam o tônus uterino e assim promovem a involução. Quando, de forma anormal, o período de involução se prolonga além dos mecanismos fisiológicos normais, define-se a situação como retardo na involução uterina com riscos potenciais de redução da eficiência reprodutiva, pela maior probabilidade de desenvolvimento de metrite, alteração da ciclicidade pós-parto e posteriores falhas na implantação por falhas na recuperação endometrial. 2.1 Relação energia e proteína O excesso de energia antes do parto pode levar ao retardo na involução uterina por que, a acumulação em excesso de reservas, se faz na forma de tecido adiposo, o qual ao ser mobilizado, durante o periparto, em resposta à busca pelo animal de fontes de energia para a depleção do glicogênio hepático e para a redução do consumo de matéria seca, deve ativar mecanismos gliconeogênicos (ZUÑIGA, 2006). Entre os substratos para a gliconeogênese incluem-se, em primeiro lugar, o tecido adiposo. Um rápido sinal endócrino para sua mobilização provém do cortisol (em excesso durante o parto), mas na presença de grande quantidade de tecido adiposo se apresentará dois efeitos imediatos; o primeiro uma cetose aguda e o segundo a infiltração da gordura do fígado, também chamado fígado graxo. Estas duas situações alteram a homeostase, em especial do tecido uterino (que sob pouca oferta de glicose, já que a mesma está sendo utilizada por outros tecidos que na compartimentalização enérgica prevalecem sobre o tecido reprodutivo), não é abundante, assim, o miométrio não deve ter energia para manter a contractilidade induzida pelas prostaglandinas. Adicionalmente as prostaglandinas são estruturalmente um ácido graxo insaturado composto por 20 átomos de carbono (ácido araquidônico) que necessita da enzima ciclo-oxigenase que dá origem à síntese de compostos intermediários instáveis chamados endoperóxidos cíclicos (PGG e PGH) (BARRERA, 2003), indispensáveis para a formação da prostaglandina e que não podem ser sintetizados por estar alterado o mecanismo lipogênico. Da mesma forma, o fator contrário em relação ao balanço energético preparado, isto é, em casos de deficiência de energia no preparo, leva a involução uterina retarda mediante um mecanismo que finalmente se assemelha ao apresentado em excesso de energia, mas através de um processo fisiológico em alguns pontos diferentes. Dependendo da gravidade do déficit energético, o catabolismo tecidular pode atingir magnitudes exageradas e, se a ele se somam os excessos de amônio formado pelo déficit de energia a nível ruminal, é provável que fenômenos fisiológicos se convertam em patológicos. A rápida perda de condição corporal, afeta o desempenho reprodutivo devido aos efeitos da excessiva taxa de mobilização dos tecidos sobre a saúde do útero e sua motilidade, já que não se encontrará possibilidade de síntese de prostaglandinas por déficit nos precursores lípidos e tampouco haverá glicose disponível como combustível energético, além disso, o atraso na involução uterina está intimamente relacionada com o balanço energético negativo (BEN) e os seus efeitos na concentração de metabolitos que influenciam o balanço hormonal, em especial sobre os estrógenos. Igualmente, no início da lactação o balanço energético negativo é o resultado de uma alta relação entre a hormona do crescimento e a insulina no sangue, que promove a mobilização de ácidos graxos de cadeia longa do tecido adiposo (ZUÑIGA, 2006). O BEN provoca alterações nas concentrações de metabolitos e hormonas como a glicose, a insulina, a hormona do crescimento (GH) (GALVIS, et al. 2003) e o fator insulínico de crescimento tipo 1 (IGF-1)que estão envolvidos no metabolismo energético intermediário e informam do estado nutricional do hipotálamo afetando a secreção de GnRH atrasando, dessa maneira, o tempo de involução uterina. Ações bloqueadoras mediadas por opioides endógenos que freiam a liberação de FSH e dela derivada, ocorre uma menor síntese de estrogênios que ativam receptores específicos no endométrio e não promovem contractilidade endometrial. Para suprir as necessidades das fêmeas quanto a proteínas e energias, os farelos de milho, soja, arroz, algodão, girassol, amendoim, etc., suprem muito bem as quantidades necessárias. Para tanto, faz-se necessário o cálculo correto das quantidades a serem disponibilizadas na ração, bem como ao cálculo da quantidade fornecida no cocho para o animal, uma vez que a ingestão superior de determinados elementos como o molibdênio, a exemplo, podem causar diversos transtornos para além dos reprodutivos. As forrageiras podem suprir as fontes de energia e proteínas das fêmeas, como as leguminosas por exemplo, em especial a leucena, que serve como alternativa alimentar para a alimentação dos animais, porém mesmo com o fornecimento à vontade das forrageiras como os capins, é necessária uma complementação e a ração concentrada é o melhor remédio para tal. 2.2 Minerais Sabe-se que as deficiências de alguns minerais, incluindo o cálcio, fósforo, cobalto, cobre, iodo, manganês e selênio e os excessos de molibdênio afetam diretamente o sistema reprodutivo (MONCADA, 2001). Suas deficiências correm paralelas com alterações do eixo hipotálamo-hipófise-ovário. Sendo o cálcio um elemento indispensável na contractilidade do útero, seu déficit na dieta poderia ser responsável por uma involução uterina inadequada (RÚGELES, 2001). O cobalto é necessário no rúmen para a formação da vitamina B12. Quando ocorre uma deficiência de cobalto observa-se, primeiro, uma diminuição no consumo de alimentos e, com isso, uma baixa síntese de glicose, um consumo anormal de minerais (pica ou depravação do gosto) e uma queda na produção. Como consequência, pode-se afetar indiretamente, tanto a quantidade de nutrientes consumidos como seu aproveitamento refletindo-se finalmente sobre a fertilidade em forma negativa (DEHNING, 1988). As exigências nutricionais de cobalto em bovinos de corte ou leite, são escassas a nível de pesquisas, porém pode-se obter através da ingestão de matéria seca (MS) sobre um coeficiente fixo que é 0,1, esse número é o pico do fornecimento de cobalto, uma vez ultrapassado a quantidade de 0,1 mg/kg os animais serão acometidos por altos índices de toxidade, por isso o criador deve estar atento ao fornecimento desse microelemento aos animais. Porém, segundo estudos, o intervalo sugerido em quantidades desse elemento é de 0,07 e 0,11 mg/kg. Alguns cereais podem disponibilizar o cobalto em concentrações ideais, porém é melhor a prevenção, sendo assim, a deficiência de cobalto pode ser prevenida ou tratada mediante a adição de sais de cobalto às misturas minerais ingredientes da ração fornecida aos animais, ou pode-se optar pela injeção da vitamina B12 diretamente no animal. Da mesma forma que a deficiência de cálcio e fósforo, na deficiência de cobre, é observado um aumento da involução uterina retardada, calores silenciosos e ciclos estrais irregulares, uma vez que as funções deste mineral estão associadas às enzimas relacionadas com o citocromo C oxidase, transporte de albumina e ceruloplasmina, esta última de vital importância como principal oxidadora de ferro e ativadora nos processos de regulação dos mecanismos antioxidantes a nível celular. Não deve-se esquecer a estreita relação entre cobre e molibdênio. Excessos de molibdênio inibem a absorção de cobre. Em animais criados à pasto, deve-se estar atento a áreas onde as concentrações de molibdênio são mais presentes, se houver grande quantidade desse elemento nas forrageiras que o animal consumir, a melhor maneira de suplementação do cobre nesses animais é a injeção periódica de compostos a base de cobre, que evitarão a complexação do trato gastrointestinal. Os bovinos requerem 8,0 mg/kg (4 – 10 mg/kg) de cobre na dieta para corte e de 10,0 mg/kg (9 – 11 mg/kg) na dieta para bovinos leiteiros. Além da opção de ração que contenha esses níveis de cobre, o criador pode optar pelas forragens, que possuem quantidades variadas de cobre dependendo da disponibilidade do mesmo no solo, e que as leguminosas apresentam os melhores valores para que os animais possam consumir as quantidades essenciais para que não haja nem cobre demais nem cobre de menos no organismo, e que evite-se, com isso a involução uterina ou quaisquer outra doença reprodutiva ou não. A deficiência de iodo induzida pelo consumo de forragens com níveis inferiores a 2 mg/kg de Matéria Seca (MS) ou baixa suplementação mineral, induz a retenção de membranas fetais e involuções uterinas retardadas. A tiroxina (T4) e a triiodotironina (T3) estimulam a produção de ATP mitocondrial, o que, por sua vez, estimula a captação celular de oxigênio e aumenta o metabolismo energético. Em casos de deficiência de iodo, as tiroxinas não poderão ser sintetizadas (RÚGELES, 2001). -/- REFERÊNCIAS BIBLIOGRÁFICAS BARRERA, R. Las prostaglandinas: Estrategia Farmacológica.
