Despite evidence indicating that public health services are the most effective means of improving the population's health status, health care services receive the bulk of funding and political support. The recent passage of the Affordable Care Act, which focused on improving access to health care services through insurance reform, reflects the primacy of health care over public health. Although policymakers typically conceptualize health care and public health as two distinct systems, gains in health status are most effectively and cost-efficiently achieved (...) through their integration into a single health system. The Act does little to compel integration; however, there are numerous opportunities to encourage the coordination of public health and health care in the Act's implementation. (shrink)
Heath care and public health are typically conceptualized as separate, albeit overlapping, systems. Health care’s goal is the improvement of individual patient outcomes through the provision of medical services. In contrast, public health is devoted to improving health outcomes in the population as a whole through health promotion and disease prevention. Health care services receive the bulk of funding and political support, while public health is chronically starved of resources. In order to reduce morbidity and mortality, policymakers must shift their (...) attention to public health services and to the improved integration of health care and public health. In other words, health care and public health should be treated as two parts of a single integrated health system. Furthermore, in order to maximize improvements in health status, policymakers must consider the impact of all governmental policies on health. (shrink)
We present a population density and moment-based description of the stochastic dynamics of domain $${\text{Ca}}^{2+}$$ Ca 2 + -mediated inactivation of L-type $${\text{Ca}}^{2+}$$ Ca 2 + channels. Our approach accounts for the effect of heterogeneity of local $${\text{Ca}}^{2+}$$ Ca 2 + signals on whole cell $${\text{Ca}}^{2+}$$ Ca 2 + currents; however, in contrast with prior work, e.g., Sherman et al. :985–995, 1990), we do not assume that $${\text{Ca}}^{2+}$$ Ca 2 + domain formation and collapse are fast compared to channel gating. (...) We demonstrate the population density and moment-based modeling approaches using a 12-state Markov chain model of an L-type $${\text{Ca}}^{2+}$$ Ca 2 + channel introduced by Greenstein and Winslow :2918–2945, 2002). Simulated whole cell voltage clamp responses yield an inactivation function for the whole cell $${\text{Ca}}^{2+}$$ Ca 2 + current that agrees with the traditional approach when domain dynamics are fast. We analyze the voltage-dependence of $${\text{Ca}}^{2+}$$ Ca 2 + inactivation that may occur via slow heterogeneous domain [ $${\text{Ca}}^{2+}$$ Ca 2 + ]. Next, we find that when channel permeability is held constant, $${\text{Ca}}^{2+}$$ Ca 2 + -mediated inactivation of L-type channels increases as the domain time constant increases, because a slow domain collapse rate leads to increased mean domain [ $${\text{Ca}}^{2+}$$ Ca 2 + ] near open channels; conversely, when the maximum domain [ $${\text{Ca}}^{2+}$$ Ca 2 + ] is held constant, inactivation decreases as the domain time constant increases. Comparison of simulation results using population densities and moment equations confirms the computational efficiency of the moment-based approach, and enables the validation of two distinct methods of truncating and closing the open system of moment equations. In general, a slow domain time constant requires higher order moment truncation for agreement between moment-based and population density simulations. (shrink)
For years a debate has raged within the various literatures of philosophy, psychiatry, and psychology over whether, and to what degree, the concepts that characterize psychopathology are social constructions that reflect cultural values. While the majority position among philosophers has been normativist, i.e., that the conception of a mental disorder is value-laden, a vocal and cogent minority have argued that psychopathology results from malfunctions that can be described by terminology that is objective and scientific. Scientists and clinicians have tended to (...) endorse the objectivist position, with some notable exceptions. (shrink)
En este artículo se plantea una discusión con el enfoque doxástico de los delirios. A pesar de que esta línea de análisis ha hecho importantes aportes en cuanto a la comprensión del fenómeno, tiene dificultades importantes a la hora de aportar un marco explicativo completo de los delirios porque deja por fuera el aspecto total de la experiencia y sigue basándose implícitamente en la idea de que podemos estudiar de manera separada e independiente los aspectos físicos, cognitivos y experienciales de (...) un fenómeno tan complejo. Se propondrá que, más allá de la decisión acerca de si debemos considerar a los delirios como creencias irracionales o no, o de si puede concebírselos como creencias en absoluto, es necesario tener en cuenta la transformación drástica del mundo entero de experiencia que se da en el sujeto delirante, tal como lo plantea la fenomenología.

The commentaries by Contesi, Hardcastle, Pismenny, and Gallegos pose pressing questions about the nature of boredom, frustration, and anticipation. Although their questions concern specific claims that I make in Propelled, they are of broad philosophical interest for, ultimately, they pave the way for a better understanding of these three psychological states. In my responses to the commentators, I clarify certain claims made in Propelled; provide additional support for my understanding of frustration; articulate the relationship between effort and value; defend (...) the claim that boredom is an emotion and discuss its formal object; and finally, consider the relationship between boredom (ordinarily understood) and deep or profound boredom. I am grateful to the commentators for engaging with Propelled. (shrink)
Evolutionary psychologists claim that the mind contains “hundreds or thousands” of “genetically specified” modules, which are evolutionary adaptations for their cognitive functions. We argue that, while the adult human mind/brain typically contains a degree of modularization, its “modules” are neither genetically specified nor evolutionary adaptations. Rather, they result from the brain’s developmental plasticity, which allows environmental task demands a large role in shaping the brain’s information-processing structures. The brain’s developmental plasticity is our fundamental psychological adaptation, and the “modules” that result (...) from it are adaptive responses to local conditions, not past evolutionary environments. If different individuals share common environ- ments, however, they may develop similar “modules,” and this process can mimic the development of genetically specified modules in the evolutionary psychologist’s sense.

Is God's foreknowledge compatible with human freedom? One of the most attractive attempts to reconcile the two is the Ockhamistic view, which subscribes not only to human freedom and divine omniscience, but retains our most fundamental intuitions concerning God and time: that the past is immutable, that God exists and acts in time, and that there is no backward causation. In order to achieve all that, Ockhamists distinguish ‘hard facts’ about the past which cannot possibly be altered from ‘soft facts’ (...) about the past which are alterable, and argue that God's prior beliefs about human actions are soft facts about the past.

An important contribution to the foundations of probability theory, statistics and statistical physics has been made by E. T. Jaynes. The recent publication of his collected works provides an appropriate opportunity to attempt an assessment of this contribution.
É bem conhecida a oposição estabelecida por Kant entre experiência possível e dialética, na medida em que esta última é caracterizada como a lógica da ilusão. Ao mesmo tempo, o modo de pensar metafísico, que ocorre dialeticamente, em sentido kantiano, é uma tendência inevitável da razão, expressa na exigência formal de completude das categorias. Como o pensar, enquanto exercício livre da razão, é em si mesmo mais amplo do que a atividade de conhecer, própria do entendimento, o pensar contém o (...) conhecimento, embora este se qualifique pelas regras e pelos limites determinantes da objetividade. A pergunta que tentaremos formular é se essa relação continente-conteúdo não poderia configurar também uma dependência da experiência em relação ao raciocínio dialético, que estaria de algum modo indicada na função reguladora das idéias da razão. Nesse caso, a oposição formal entre conhecer e pensar seria inseparável da inclusão estrutural (dependência) da experiência no âmbito da razão. Na raiz do problema estaria talvez a tensão (dialética) entre a aspiração subjetiva de totalidade e as exigências objetivas de limitação e segmentação da experiência e a forma da experiência teria de ser finalmente concebida a partir de um fundo de inteligibilidade problemática. Dialectics and experienceThe separation of possible experience as objective knowledge and dialetics as a non-objective or non-theoretical knowledge is one of the most important aspects of kantian critical philosophy. But Kant also says that the activity of reason, as a pure thinking, has more amplitude than understanding knowledge. So we could say that theoric knowledge would depend on rational ( and non-theoretical) knowledge, as something contained in it. If we accept that, the consequence would be a relation of dependence between the form of objective knowledge and the background of a problematic even doubtful inteligible knowledge. (shrink)
What is a natural kind ? As we shall see, the concept of a natural kind has a long history. Many of the interesting doctrines can be detected in Aristotle, were revived by Locke and Leibniz, and have again become fashionable in recent years. Equally there has been agreement about certain paradigm examples: the kinds oak, stickleback and gold are natural kinds, and the kinds table, nation and banknote are not. Sadly agreement does not extend much further. It is impossible (...) to discover a single consistent doctrine in the literature, and different discussions focus on different doctrines without writers or readers being aware of the fact. In this paper I shall attempt to find a defensible distinction between natural and non-natural kinds. (shrink)
Wittgenstein’s concepts shed light on the phenomenon of schizophrenia in at least three different ways: with a view to empathy, scientific explanation, or philosophical clarification. I consider two different “positive” wittgensteinian accounts―Campbell’s idea that delusions involve a mechanism of which different framework propositions are parts, Sass’ proposal that the schizophrenic patient can be described as a solipsist, and a Rhodes’ and Gipp’s account, where epistemic aspects of schizophrenia are explained as failures in the ordinary background of certainties. I argue that (...) none of them amounts to empathic-phenomenological understanding, but they provide examples of how philosophical concepts can contribute to scientific explanation, and to philosophical clarification respectively.

How could the self be a substance? There are various ways in which it could be, some familiar from the history of philosophy. I shall be rejecting these more familiar substantivalist approaches, but also the non-substantival theories traditionally opposed to them. I believe that the self is indeed a substance—in fact, that it is a simple or noncomposite substance—and, perhaps more remarkably still, that selves are, in a sense, self-creating substances. Of course, if one thinks of the notion of substance (...) as an outmoded relic of prescientific metaphysics—as the notion of some kind of basic and perhaps ineffable stuff —then the suggestion that the self is a substance may appear derisory. Even what we ordinarily call ‘stuffs’—gold and water and butter and the like—are, it seems, more properly conceived of as aggregates of molecules or atoms, while the latter are not appropriately to be thought of as being ‘made’ of any kind of ‘stuff’ at all. But this only goes to show that we need to think in terms of a more sophisticated notion of substance—one which may ultimately be traced back to Aristotle's conception of a ‘primary substance’ in the Categories , and whose heir in modern times is W. E. Johnson's notion of the ‘continuant’. It is the notion, that is, of a concrete individual capable of persisting identically through qualitative change, a subject of alterable predicates that is not itself predicable of any further subject.
