In this paper we argue for a naturalistic solution to some of the methodological controversies in regulatory science, on the basis of two case studies: toxicology and health claim regulation. We analyze the debates related to the scientific evidence that is considered necessary for regulatory decision making in each of those two fields, with a particular attention to the interactions between scientific and regulatory aspects. This analysis allows us to identify two general stances in the debate: a) one that argues (...) for more permissive standards of evidence and for methodological pluralism, and b) an opposing one that not only defends strict evidence requirements but also stipulates the use of one particular scientific methodologies for data generation. We argue that the real-world outcomes produced by alternative regulatory options are a vital piece of information that allows for the empirical assessment of these two stances. In particular, this information on outcomes makes it possible to analyze which standards of evidence and scientific methods generate the most useful knowledge as input for regulatory decision making. Our conclusion is that instead of an a priori selection of methodologies and standards, such decisions ought to be based on empirical evidence related to real-world outcomes. (shrink)

Le débat sur le rôle des valeurs en science survient également dans les sciences appliquées, en particulier dans les sciences régulatives. Nous proposons une analyse, sous l’angle des valeurs, des controverses récentes sur le rôle de la connaissance scientifique dans la régulation des risques technologiques. Nous distinguons trois perspectives sur les valeurs cognitives et non-cognitives, dans le contexte de l’évaluation et de la gestion du risque. Notre analyse montre que les deux types de valeurs interagissent au sein du processus de (...) génération de connaissances dans les sciences régulatives, et que des propositions de changements méthodologiques dépendent de la reconnaissance explicite du rôle opérant des valeurs. Notre contribution indique que l’analyse philosophique des valeurs peut aider à clarifier les controverses actuelles sur les risques technologiques. (shrink)

The relevance of scientific knowledge for science and technology policy and regulation has led to a growing debate about the role of values. This article contributes to the clarification of what specific functions cognitive and noncognitive values adopt in knowledge generation and decisions, and what consequences the operation of values has for policy making and regulation. For our analysis, we differentiate between three different types of decision approaches, each of which shows a particular constellation of cognitive and noncognitive values. Our (...) objectives are to present a structured analysis of the varying functions that different kinds of values can adopt, as well as the value-related tensions and trade-offs they give rise to. We argue that the operation of noncognitive values in scientific knowledge generation, policy, and regulatory decision making can be understood as an enabling factor, rather than a limiting one.

En este trabajo analizamos una de las propuestas recientes que defienden modificaciones metodológicas en la evaluación de riesgos respecto a los estándares de prueba: el enfoque basado en el peso de las pruebas (weight of evidence). Este enfoque puede interpretarse como un caso de ciencia precautoria en la investigación sobre riesgos. Esto es, se trata de una metodología que pretende proporcionar resultados más protectores de la salud pública y del entorno que las metodologías usuales en la evaluación de riesgos. Sin (...) embargo, existe la posibilidad de que quienes se muestran en contra de la regulación de ciertas aplicaciones tecnológicas introduzcan artificialmente incertidumbre en el cuerpo de la evidencia. En consecuencia, la metodologia del peso de las pruebas no conduce de manera automática a una mayor protección de la salud pública y del ambiente. Por ello es necesario analizar cada innovación valorando los posibles riesgos y los posibles beneficios sociales, y decidir en cada caso cuál de las dos posibilidades, la subregulación o la sobrerregulación, es más aceptable. El conocimiento científico es un elemento necesario para llevar a cabo esta valoración, pero no la determina.This paper analyzes one recent proposal for modifying the metodologies used in risk assessment: the Weight-Of-Evidence (WOE) approach. This approach is an example of precautionary science in risk research, i.e. a methodology which aims at a better protection of human health and the environment. However, some groups opposed to the regulation of certain technologies have started artificially introducing uncertainties into the body of evidence. This means that the WOE approach does not automatically lead to a higher level of health or environmental protection. It is therefore necessary to analyze each innovation on a case-by-case basis in order to evaluateits risks and benefits, and decide if to accept lower or, on the contrary, higher standards for its regulation. Scientific knowledge is a necessary element in this assessment, but not the decisive one. (shrink)

Is there such a thing as a “best scientific methodology” in regulatory science? By examining cases from varying regulatory processes, we argue that there is no best scientific method for generating decision-relevant data. In addition, in regulatory science, the most suitable methodologies often differ from what is considered best practice in knowledge-oriented science. In data generation for regulatory purposes, we are faced with a wide spectrum of preferred methodologies as well as controversy as to methodological choice. What goes by the (...) most adequate scientific method can and will—justifiably and rationally—vary significantly according to context and use. In order to make this argument, we analyze four case studies, two from risk assessment and two from benefit assessment. Our analysis shows that it is the noncognitive objectives of a particular regulatory process that determine what counts as the most appropriate scientific method. We use the concept of bounded rationality to indicate that those methodological choices, despite being context-dependent, can be interpreted as rational. (shrink)

Regulatory science, which generates knowledge relevant for regulatory decision?making, is different from standard academic science in that it is oriented mainly towards the attainment of non?epistemic (practical) aims. The role of uncertainty and the limits to the relevance of academic science are being recognized more and more explicitly in regulatory decision?making. This has led to the introduction of regulation?specific scientific methodologies in order to generate decision?relevant data. However, recent practical experience with such non?standard methodologies indicates that they, too, may be (...) subject to important limitations. We argue that the attainment of non?epistemic values and aims (like the protection of human health and the environment) requires not only control of the quality of the data and the methodologies, but also the selection of the level of regulation deemed adequate in each specific case (including a decision about which of the two, under?regulation or over?regulation, would be more acceptable).

Mechanistic information is used in the field of risk assessment in order to clarify two controversial methodological issues, the selection of inference guides and the definition of standards of evidence. In this paper we present an analysis of the concept of mechanistic information in risk assessment by recurring to previous philosophical analyses of mechanistic explanation. Our conclusion is that the conceptual analysis of mechanistic explanation facilitates a better characterization of the concept of mechanistic information. However, it also shows that the (...) use of this kind of information in risk assessment is heavily influenced by pragmatic factors, which have not been sufficiently taken into account in philosophical analysis. Mechanistic models are like hypothesis that have to be validated empirically. Due to their dependence on the standards of evidence, they are subject to the same pragmatic factors. Therefore, recurring to mechanistic information does not lead to closure of the methodological controversies in risk assessment. (shrink)

The function and legitimacy of values in decision making is a critically important issue in the contemporary analysis of science. It is particularly relevant for some of the more application-oriented areas of science, specifically decision-oriented science in the field of regulation of technological risks. Our main objective in this paper is to assess the diversity of roles that non-cognitive values related to decision making can adopt in the kinds of scientific activity that underlie risk regulation. We start out, first, by (...) analyzing the issue of values with the help of a framework taken from the wider philosophical debate on science and values. Second, we study the principal conceptualizations used by scholars who have applied them to numerous case studies. Third, we appraise the links between those conceptualizations and learning processes in decision-oriented science. In this, we recur to the concept of methodological learning, i.e., learning about the best methodologies for generating knowledge that is useful for science-based regulatory decisions. The main result of our analysis is that non-cognitive values can contribute to methodological improvements in science in three principal ways: as basis for critical analysis, for contextualizing methodologies, and for establishing the burden of proof.

The issue of internalism and externalism in historiography of science was intensely debated two decades ago. The conclusions of such debate on the ‘context of science’ appear to be a reinstatement of the positivist view of the ‘content of science’ as comprising only ideas and concepts uninfluenced by extra-scientific factors. The description of the roles of politics, economy, and socio-cultural factors in science was limited only within the ‘context of science’. This article seeks to resituate the ‘content of science’ debate (...) within the historical accounts of the Scientific Revolution to illustrate that their resort to historicism indicates that such content does not emerge from the void. It argues that, though some historicist accounts like Alexandre Koyré’s reinstate the positivist argument on the nature of the ‘content of science’, such historicist internalism greatly differs from positivist internalism, largely due to its acceptance of metaphysics in science. Therefore, as long as historicism is relied on to describe the content of science, a clear-cut distinction of the historicist internalism and externalism will be difficult to establish. (shrink)

En el primer capítulo de su libro Duchesneau aborda la cuestión de lo que es una especie, algo de difícil solución porque el de especie es un concepto de una potencia heurística inmensa y, a la vez, está lleno de agujeros que se hacen patentes en cuanto se pretende hilar fino para definirlo. Las alternativas entre la especie como grupo reproductivo -la "especie biológica"- y como secuencia evolutiva -la "especie filogenética"-, con sus respectivas precisiones internas, están bien planteadas por el (...) autor. También lo está la más reciente "especie ecológica", de talante adaptacionista. Duchesneau no pretende argumentar en favor de uno u otro concepto, sino indicar que existen, y de su postura aséptica se deduce que, probablemente, es imposible reducir ninguno de esos conceptos al otro. Pero esa conclusión tropieza de inmediato con el asunto que aborda Duchesneau en el epígrafe siguiente de su libro: la taxonomía. Porque en algo coinciden al menos quienes emplean especies biológicas, filogenéticas y ecológicas: en darles un nombre. No es raro, pues, que la sistemática sea en estos momentos una de las disciplinas que tenga más interrogantes por resolver. (shrink)

School tourism constitutes a source of learning to strengthen the cultural identity of students. The objective was to compare the development of school tourism in the educational institutions San Pedro Chanel and Carlos Augusto Salaverry. The Leiper space approach was used. The exhibition was constituted by 200 high school students and 20 teachers. The results show that there is statistically significant differences regarding the knowledge of the tourist resources of the province of Sullana. It was concluded that educational tourism is (...) a strategy that tries to bring the student closer to knowledge, awareness and assessment of tourist resources. (shrink)

This paper argues for the theoretical and practical validity of similarity as a useful epistemological tool in scientific knowledge generation, specifically in chemistry. Classical analyses of similarity in philosophy of science do not account for the concept’s practical significance in scientific activities. We recur to examples from chemistry to counter the claim of authors like Quine or Goodman to the effect that similarity must be excluded from scientific practices . In conclusion we argue that more recent conceptualizations of the notion (...) of similarity, particularly Giere’s one, are appropriate for a philosophical analysis that considers scientific practices on equal terms with scientific theory.

In their recent book The Inessential Indexical Herman Cappelen and Josh Dever take issue with what has become close to philosophical orthodoxy – the view, most often associated with John Perry and David Lewis, that psychological explanations are essentially indexical. Cappelen and Dever claim that claims of essential indexicality are typically driven by intuitions rather than supported by arguments. They issue a challenge to supporters of essential indexicality: Produce an argument to back up the intuitions. This paper answers their (...) challenge. (shrink)

This volume features essays that detail the distinctive ways authors and researchers in Spanish speaking countries express their thoughts on contemporary philosophy of technology. Written in English but fully capturing a Spanish perspective, the essays bring the views and ideas of pioneer authors and many new ones to an international readership. Coverage explores key topics in the philosophy of technology, the ontological and epistemological aspects of technology, development and innovation, and new technological frontiers like nanotechnology and cloud computing. In addition, (...) the book features case studies on philosophical queries. Readers will discover such voices as Miguel Ángel Quintanilla and Javier Echeverría, who are main references in the current landscape of philosophy of technology both in Spain and Spanish speaking countries; José Luis Luján, who is a leading Spanish author in research about technological risk; and Emilio Muñoz, former head of the Spanish National Research Council and an authority on Spanish science policy. The volume also covers thinkers in American Spanish speaking countries, such as Jorge Linares, an influential researcher in ethical issues; Judith Sutz, who has a very recognized work on social issues concerning innovation; Carlos Osorio, who focuses his work on technological determinism and the social appropriation of technology; and Diego Lawler, an important researcher in the ontological aspects of technology.

RésuméLe conventionnalisme social — selon lequel les conventions sociales régissant l'usage de la langue déterminent ou constituent le sens de nos mots — s'est heurté à deux problèmes majeurs. Le premier est le problème de l'accord : comment des locuteurs peuvent-ils accepter d'utiliser des mots d'une certaine manière s'ils ne parlent pas déjà de manière significative? Le deuxième est le problème de la nouveauté : comment les conventions peuvent-elles fixer le sens des usages innovants des mots? La solution de David (...) Lewis au problème de l'accord est bien connue, mais son analyse ne résout pas le problème de la nouveauté. Josh Armstrong modifie cette analyse afin de résoudre ce dernier. Je soutiens que la correction d'Armstrong échoue et que ni lui ni Lewis n'offrent de réponse adéquate au problème de l'accord. (shrink)

Para comprender qué fue la Monarquía de los Reyes Católicos -Monarquía Católica española, como la denominaría Tommasso Campanella un siglo más tarde- tenemos que desprendernos de muchas opiniones de nuestros días e intentar referirnos a los valores, ideas y opiniones que conformaban la sociedad europea de aquel tiempo. En el tránsito de la Edad Media a la Modernidad no existía ningún valor comparable al de la fe, fundamento de toda sociedad a la que definía, haciéndola cristiana, judía o musulmana. Un (...) judío o musulmán que se convertía dejaba automáticamente de pertenecer a su sociedad pasando a integrarse en la cristiana.…. (shrink)

The presence of ibuprofen in wastewater is a topic of global interest, and the mechanisms and behavior of its correlation with its elimination in ecological systems, such as constructed wetlands, is a little known topic. The objective of this study was to perform a correlational analysis of the behavior of the emerging contaminant ibuprofen in a horizontally constructed wetland in a tropical climate planted with the ornamental plant Spathiphyllum blandum. 10 experimental units were used at the mesocosm level of 20 (...) L, 5 planted with Spathiphyllum B., and 5 without plants. The elimination of ibuprofen was measured and the correlation was analyzed using computational methods and neural networks. Spathiphyllum blandum was used in this study. The removal of ibuprofen in HC was significantly improved by up to 23% compared with that in non-planted systems. Based on the prediction obtained from ibuprofen in the effluent, it can be concluded that it has an exponential decay behavior tending to zero, and the model obtained explains in an acceptable way the relationship between the height of the plant and the concentration of ibuprofen in the effluent, reaffirming that this relationship is inverse. Further studies should be conducted to understand the behavior of these compounds in relation to different species of tropical plants. (shrink)

In recent years, some scholars and prominent political figures have advocated the deepening of North American integration on roughly the European Union model, including the creation of new political institutions and the free movement of workers across borders. The construction of such a North American Union, if it included even a very thin trans-state citizenship regime, could represent the most significant expansion of individual entitlements in the region since citizenship was extended to former slaves in the United States. With such (...) a possibility as its starting point, this article explores some striking parallels between the mass, legally prohibited movement across boundaries by fugitive slaves in the pre-Civil War period, and that by current unauthorized migrants to the United States. Both were, or are, met on their journeys by historically parallel groups of would-be helpers and hinderers. Their unauthorized movements in both periods serve as important signals of incomplete entitlements or institutional protections. Most crucially, moral arguments for extending fuller entitlements to both groups are shown here to be less distinct than may be prima facie evident, reinforcing the case for expanding and deepening the regional membership regime.
