Este artículo examina las diferentes conceptualizaciones del sistema cognitivo de los docentes, desde la perspectiva socioconstructivista. Aborda la cognición como una base conceptual, personal, subjetiva y dinámica que tiene un impacto significativo en la actuación docente y en el proceso de cambio en educación. El proceso de exploración de la cognición docente puede ayudar a enriquecer la conceptualización sobre el proceso didáctico, y, además, puede servir como base para la autoevaluación docente, componente importante del desarrollo profesional en la Educación Superior.
Ha sido mi interés en los últimos años reflexionar formalmente sobre la conciencia en referencia a sus fundamentos y aspectos biológicos, en especial los cerebrales y los de comportamiento. Urdiendo sobre sus aspectos fisiológicos, fenomenológicos, epistemológicos y ontológicos, he explorado la naturaleza del dolor como un estado paradigmático de conciencia en un cuento de “neurociencia ficción” (Díaz, 2002), en un trabajo publicado en Salud Mental (Díaz, 2007) y en un libro sobre la conciencia viviente (Díaz, 2007). Estos análisis utilizan al (...) dolor como un fenómeno de conciencia fértil para examinar las principales conjeturas vigentes sobre la relación mente cuerpo y el problema epistemológico del acceso científico a la conciencia. La presente comunicación es un breve repaso de las principales ideas exploradas que se especifican en un decálogo de afirmaciones sobre la naturaleza y el conocimiento del dolor. Medical Epistemology: Ten Postulates on Pain It has been my interest in recent years to formally reflect on consciousness’s biological aspects and foundations, especially the brain-related and behavioral ones. In dwelling on its physiological, phenomenological, epistemological and ontological aspects, I have explored the nature of pain as a paradigmatic state of consciousness in a “neuroscience-fiction” tale (Díaz, 2002), in a work published in Mental Health (Díaz, 2007), and in a book on living consciousness (Díaz, 2007). These analyses use pain as a fertile consciousness phenomenon in order to examine the main current conjectures on the mind-body relation and the epistemological problem of scientific access to consciousness. This work is a brief summary of the main ideas explored, specified as a Decalogue of statements on the nature and knowledge of pain. (shrink)
¿Existe una incompatibilidad estructural entre fe religiosa y logos filosófico? Así parecen darlo por supuesto diversas orientaciones filosóficas de la modernidad. Sin embargo, el cristianismo ha convivido desde siempre con la filosofía, la ha acogido y cultivado. Carlos Díaz presenta en este breve trabajo la sintonía profunda que se da en la concreción real del ser humano entre el logos filosófico y el propio de la experiencia religiosa.
Los años 80 han atraido, en los últimos tiempos, una serie de miradas nostálgicas, sobre todo hacia su música. Lejos de esa atmósfera está “ El Canto Nuevo de Chile. Un Legado Musical ”, de Patricia Díaz-Inostroza.Por el contrario, se trata de una investigación que, si bien está centrada en el movimiento llamado Canto Nuevo, abarca mucho más que eso, dejando en claro las profundas raíces históricas que afirman este tipo de música. Ese es un aporte innegable, que permite (...) al lector (o lectora) .. (shrink)
Dual aspect theory has conceptual advantages over alternative mind-body notions, but difficulties of its own. The nature of the underlying psychophysical ground, for one, remains problematic either in terms of the principle of complementarity or if mind and matter are taken to be aspects of something like energy, movement, or information. Moreover, for a dual aspect theory to be plausible it should avoid the four perils of all mind-body theories: epiphenomenalism, reductionism, gross panpsychism, and the problems of emergence. An alternative (...) dual aspect theory, patterned process theory, is introduced and defended in neurological and individuality terms. The concept is grounded in a brain model of hierarchies wherein consciousness is conceived to be a cognitive aspect of the highest emergent brain inter-module activity, which is situated in the context of a living organism coping with a changing environment. The notion of individuals as psychophysical units unfolding as patterned processes is shown to constitute an integrative approach to brain, consciousness, and behavior that can avoid the conceptual perils and meet the ontological requirements of dual aspect reality and thereby advance the foundations of an integrative mind-body science.

Botanical preparations used by shamans in rituals for divination, prophecy, and ecstasy contain widely different psychoactive compounds, which are incorrectly classified under a single denomination such as “hallucinogens,” “psychedelics,” or “entheogens.” Based on extensive ethnopharmacological search, I proposed a psychopharmacological classification of magic plants in 1979. This paper re-evaluates this taxonomy in the context of consciousness research. Several groups of psychodysleptic magic plants are proposed: (1) hallucinogens—psilocybin mushrooms, mescaline cacti, dimethyltryptamine snuffs, and the synthetic ergoline lysergic acid diethylamide induce strong (...) perceptual changes, affective intensification, and cognitive enhancement. Their ethnobotanical uses include long lasting divination rituals, prophecy, and sacramental practice. (2) Trance-inducers—ergoline Convolvulaceae and South American Banisteriopsis produce quietness, abstraction, lethargy, mild sensorial and cognitive changes, and salient visual imagery changes used in trance rituals and specific divination practices. (3) Cognodysleptics—marijuana (tetrahydrocannabinol) and other terpene-containing plants induce changes in thought, imagination, and affective functions and are used in short-term divination or oneiromancy. (4) Deliriants—tropane-containing Solanaceae, wild tobacco, and Amanita muscaria (muscimol) induce a delirium characterized by dim and clouded consciousness, stupor, confusion, disorientation, perception distortion, difficulties in recollection, anxiety, irritability, excitation, and behavioral disorganization employed in sorcery, purification, or exorcism rituals. The core mental effects required for a drug to be used in shamanistic rituals include light-headedness, enhanced imagery, and experience intensification. This constellation was the reason why, in his classification of psychoactive compounds, the pioneer German psychopharmacologist Louis Lewin established in 1924 a group of drugs under the appropriate name of Phantastica.

The syllogism and the predicate calculus cannot account for an ontological argument in Descartes' Fifth Meditation and related texts. Descartes' notion of god relies on the analytic-synthetic distinction, which Descartes had identified before Leibniz and Kant did. I describe how the syllogism and the predicate calculus cannot explain Descartes' ontological argument; then I apply the analytic-synthetic distinction to Descartes’ idea of god.
Oaksford and Chater (1994) proposed to analyse the Wason selection task as an inductive instead of a deductive task. Applying Bayesian statistics, they concluded that the cards that participants tend to select are those with the highest expected information gain. Therefore, their choices seem rational from the perspective of optimal data selection. We tested a central prediction from the theory in three experiments: card selection frequencies should be sensitive to the subjective probability of occurrence for individual cards. In Experiment 1, (...) expected frequencies of the p- and the q-card were manipulated independently by concepts referring to large vs. small sets. Although the manipulation had an effect on card selection frequencies, there was only a weak correlation between the predicted and the observed patterns. In the second experiment, relative frequencies of individual cards were manipulated more directly by explicit frequency information. In addition, participants estimated probabilities for the four logical cases and of the conditional statement itself. The experimental manipulations strongly affected the probability estimates, but were completely unrelated to card selections. This result was replicated in a third experiment. We conclude that our data provide little support for optimal data selection theory. (shrink)
The societal and ethical impacts of emerging technological and business systems cannot entirely be foreseen; therefore, management of these innovations will require at least some ethicists to work closely with researchers. This is particularly critical in the development of new systems because the maximum degrees of freedom for changing technological direction occurs at or just after the point of breakthrough; that is also the point where the long-term implications are hardest to visualize. Recent work on shared expertise in Science & (...) Technology Studies (STS) can help create productive collaborations among scientists, engineers, ethicists and other stakeholders as these new systems are designed and implemented. But collaboration across these disciplines will be successful only if scientists, engineers, and ethicists can communicate meaningfully with each other. The establishment of a trading zone coupled with moral imagination present one method for such collaborative communication. (shrink)
There has been relatively little empirical research into the causes of research misconduct. To begin to address this void, the authors collected data from closed case files of the Office of Research Integrity (ORI). These data were in the form of statements extracted from ORI file documents including transcripts, investigative reports, witness statements, and correspondence. Researchers assigned these statements to 44 different concepts. These concepts were then analyzed using multidimensional scaling and cluster analysis. The authors chose a solution consisting of (...) seven clusters: (1) personal and professional stressors, (2) organizational climate, (3) job insecurities, (4) rationalizations A, (5) personal inhibitions, (6) rationalizations B and, (7) personality factors. The authors discuss the implications of their findings for policy and for future research. (shrink)
A well-known thought experiment has us ponder a lottery system that selects one person as the source of transplantable organs for two others. The organs are forcibly harvested and the “donor” dies, whereas the other two patients live. The Survival Lottery is supposed to get at the distinction between killing and letting die, but it is also a challenge to beliefs about moral duties: what are my obligations if my life could be used to save yours and another person's as (...) well? A less extreme version of this thought experiment might have us imagining that officials of the public healthcare system would devise a similar lottery in the aftermath of a large-scale medical emergency. We could imagine that a natural disaster or an attack using biological weapons, for example, has so diminished the ability to provide public health care that in some communities, officials might consider implementing a lottery. To avoid the concerns about outright killing of selectees, officials might offer a wide range of participation in medical practice and research, not just organ allocation. Officials could ensure that no significant risks are involved, and selectees could in various ways be compensated. Would it be possible to ethically justify this “Healthcare Lottery” on the grounds that it was a temporary, yet necessary, infringement on autonomy? (shrink)
Burning fossil fuel in the North American continent contributes more to the CO2 global warming problem than in any other continent. The resulting climate changes are expected to alter food production. The overall changes in temperature, moisture, carbon dioxide, insect pests, plant pathogens, and weeds associated with global warming are projected to reduce food production in North America. However, in Africa, the projected slight rise in rainfall is encouraging, especially since Africa already suffers from severe shortages of rainfall. For all (...) regions, a reduction in fossil fuel burning is vital. Adoption of sound ecological resource management, especially soil and water conservation and the prevention of deforestation, is important. Together, these steps will benefit agriculture, the environment, farmers, and society as a whole. (shrink)
Despite the prominence of healthcare-relatedconcerns in public debate, the ground remainsinfertile for the idea of conscripting citizensinto medical research. Reluctance to entertainthe thought of a system where nearly everyonecould be selected for service might reflectuncertainty about what the project wouldinvolve. There might also be a fear that themore crucial issue is how to protect researchsubjects within current, voluntary systems. Nodoubt reluctance to explore a system ofuniversal service results from the common hopethat each of us might avoid research in anycapacity besides (...) researcher. A system of fullcivic participation might, however, avoid manyof the usual objections. Ethics regulations,including informed-consent guidelines, couldfor the most part remain in force. Though thesystem would compel people to serve, it couldremain responsive to principles of autonomy andjustice if it centered on broad publiceducation, community representation, and alottery-type selection process. The systemcould draw from the largest possiblecross-section of society, and offer conscriptsthe widest possible range of service. In thisway, a compulsory system might reconcile theexpectations about healthcare with researchneeds. (shrink)
Scientific-technological innovation (particularly in the field of transgenic foods and cloning), scientific journalism and public opinion all share a complex relationship. The rupture of internal consensus among the scientific community, the role played by scientific journalists as "mediators" and the differentiation between what can be referred to as the "informed public" or "epistemological leaders" and the rest of the population were the starting point for our research on the impact of news related to biotechnological advances. In this paper we will (...) show the principal characteristics of the discourse on this type of news among what we can call the "informed public". From there, we will establish a set of strategies for improving the level of scientific-technological alphabetisation in our complex societies. (shrink)
The current ethical structure for collaborative international health research stems largely from developed countries' standards of proper ethical practices. The result is that ethical committees in developing countries are required to adhere to standards that might impose practices that conflict with local culture and unintended interpretations of ethics, treatments, and research. This paper presents a case example of a joint international research project that successfully established inclusive ethical review processes as well as other groundwork and components necessary for the (...) conduct of human behavior research and research capacity building in the host country.

In pseudo-patient study (PPS), fieldworkers cloak their identities and intentions and pose as This enables them to observe the practice of healthcare from within a naturalistic, nonreactive research setting. Rosenhan and his assistants conducted the most famous PPS, where they faked symptoms of schizophrenia so that they could gain admittance to a mental-health facility and observe the treatment that genuine patients were receiving. More subtle pseudo-patients might arrange over the phone, after reporting varying levels of health insurance. Others might provide (...) dummy lab specimens or test a physician's response to technical questions. A few genuine patients have transformed their legitimate stays in the hospital into fieldwork, transforming themselves into disguised participant-observers. (shrink)
A focus of criticism on methodological and ethical grounds, the undercover or `covert' approach to fieldwork persists as a useful technique in certain settings. Questions remain about the credibility of the published findings from such work. Covert researchers nearly always protect the anonymity of their subjects and locations. Other researchers cannot validate the covert researcher's claims, yet ethical guidelines often insist that researchers demonstrate the benefits that derive from a covert study. If researchers cannot show that their studies will prove (...) beneficial, ethical standards will weigh against the study, on the presumption that the omission of informed consent should be counterbalanced by the scientific rewards of the research. An attempt to open the results to greater peer investigation might place subjects at risk of unwanted notoriety or even danger. There does not seem to be a way that covert research can meet ethical guidelines unless we adjust our conceptions of research, ethics, or both. Key Words: fieldwork ethnography research ethics informed consent. (shrink)
The architecture of brain, consciousness, and behavioral processes is shown to be formally similar in that all three may be conceived and depicted as Petri net patterned processes structured by a series of elements occurring or becoming active in stochastic succession, in parallel, with different rhythms of temporal iteration, and with a distinct qualitative manifestation in the spatiotemporal domain. A patterned process theory is derived from the isomorphic features of the models and contrasted with connectionist, dynamic system notions. This empirically (...) derived formulation is considered to be optimally compatible with the dual aspect theory in that the foundation of the diverse aspects would be a highly structured and dynamic process, the psychophysical neutral “ground” of mind and matter posed (but not properly determined) by dual aspect and neutral monist theories. It is methodologically sound to approach each one of these processes with specific tools and to establish concurrences in real time between them at the organismic level of analysis. Such intra-level and inter-perspective correlations could eventually constitute psychophysical bridge-laws. A mature psychology of consciousness is necessary to situate and verify the bridges required by a genuine mind-body science. (shrink)
Drawing on the work of John Rawls and Thomas Pogge, I argue that the U.S. is in part responsible for the immigration of Mexicans and Central Americans into the U.S. By seeking to further its national interests through its foreign policies, the U.S. has created economic and politically oppressive conditions that Mexican and Central American people seek to escape. The significance of this project is to highlight the role of the U.S. in illegal immigration so that we may first acknowledge (...) our responsibility in order to seek lasting humane solutions.

The article approaches Salomon Maimon’s reinterpretation of the notions of the thing in itself and the given within the framework of criticism. For Maimon they do not refer to a transcendence that is directly unattainable by knowledge. In this attempt, he tries to explain the given on the basis of the action of constitutive understanding. With this, he triggers the passage from transcendental Kantian philosophy to the idealism of Fichte. Nonetheless, his position faces the subsequent problem of explaining how the (...) constitution of the given from understanding (infinite) can become compatible with the criticism it takes on. On affirming that an uncognoscible item is the basis of knowledge, namely, infinite understanding, he set aside the explanation of knowledge in terms of what is revealed in it and in doing so would be resorting to external uncognoscible conditions.

This essay represents a critical reading, appreciation and assessment of responses written by Susan Abraham, Conrad T. Gromada, and Michael Barnes to my book On Being Human: U.S Hispanic and Rahnerian Perspectives (Orbis Books, 2001). The essay addresses the following three themes: 1) Rahner’s Ignatian heritage and its relation to the U.S. Hispanic appropriation of the preferential option for the poor and marginalized, 2) Rahner’s understanding of one mediator and many human mediations, and 3) Rahner’s transcendental theological approach in relation (...) to the experience of contemporary manifestations of atheism in the U.S. These themes highlight aspects of my book that Abraham, Gromada, and Barnes found fertile ground for engaging in theological conversation. First, with respect to Rahner’s Ignatian spirituality, I argue that the Ignatian understanding of indiferencia can be correlated with the preferential option for the poor and marginalized. Second, with respect to Rahner’s understanding of one mediator and many mediations, I explore other ways in which my book could contextualize Rahner’s approach. Finally, I underscore the historical moment in Rahner’s transcendental theological approach (the mystery of God encountered in, with, and under historical realities) and point to a contemporary implication of this understanding (e.g., practical atheism).

Purpose: This study explores social networkers' interest in and attitudes toward personal genome testing (PGT), focusing on expectations related to the clinical integration of PGT results. Methods: An online survey of 1,087 social networking users was conducted to assess 1) use and interest in PGT; 2) attitudes toward PGT companies and test results; and 3) expectations for the clinical integration of PGT. Descriptive statistics were calculated to summarize respondents' characteristics and responses. Results: Six percent of respondents have used PGT, 64% (...) would consider using PGT, and 30% would not use PGT. Of those who would consider using PGT, 74% report they would use it to gain knowledge about disease in their family. 34% of all respondents consider the information obtained from PGT to be a medical diagnosis. 78% of those who would consider PGT would ask their physician for help interpreting test results, and 61% of all respondents believe physicians have a professional obligation to help individuals interpret PGT results. Conclusion: Respondents express interest in using PGT services, primarily for purposes related to their medical care and expect physicians to help interpret PGT results. Physicians should therefore be prepared for patient demands for information and counsel on the basis of PGT results. (shrink)
