In this paper, we propose a general copula approach to accommodate non-normal continuous mixing distributions in multinomial probit models. In particular, we specify a multivariate mixing distribution that allows different marginal continuous parametric distributions for different coefficients. A new hybrid estimation technique is proposed to estimate the model, which combines the advantageous features of each of the maximum simulated likelihood inference technique and Bhat’s maximum approximate composite marginal likelihood inference approach. The effectiveness of our formulation and inference approach is demonstrated (...) through simulation exercises and an empirical application. (shrink)

In Emotions and Reasons, Patricia Greenspan offers an evaluative theory of emotion that assigns emotion a role of its own in the justification of action. She analyzes emotions as states of object-directed affect with evaluative propositional content possibly falling short of belief and held in mind by generalized comfort or discomfort.

What is morality? Where does it come from? And why do most of us heed its call most of the time? In Braintrust, neurophilosophy pioneer Patricia Churchland argues that morality originates in the biology of the brain. She describes the "neurobiological platform of bonding" that, modified by evolutionary pressures and cultural values, has led to human styles of moral behavior. The result is a provocative genealogy of morals that asks us to reevaluate the priority given to religion, absolute rules, and (...) pure reason in accounting for the basis of morality. Moral values, Churchland argues, are rooted in a behavior common to all mammals--the caring for offspring. The evolved structure, processes, and chemistry of the brain incline humans to strive not only for self-preservation but for the well-being of allied selves--first offspring, then mates, kin, and so on, in wider and wider "caring" circles. Separation and exclusion cause pain, and the company of loved ones causes pleasure; responding to feelings of social pain and pleasure, brains adjust their circuitry to local customs. In this way, caring is apportioned, conscience molded, and moral intuitions instilled. A key part of the story is oxytocin, an ancient body-and-brain molecule that, by decreasing the stress response, allows humans to develop the trust in one another necessary for the development of close-knit ties, social institutions, and morality. A major new account of what really makes us moral, Braintrust challenges us to reconsider the origins of some of our most cherished values. (shrink)

Anydomainofscientificresearchhasitssustainingorthodoxy. Thatis, research on a problem, whether in astronomy, physics, or biology, is con- ducted against a backdrop of broadly shared assumptions. It is these as- sumptionsthatguideinquiryandprovidethecanonofwhatisreasonable-- of what "makes sense." And it is these shared assumptions that constitute a framework for the interpretation of research results. Research on the problem of how we see is likewise sustained by broadly shared assump- tions, where the current orthodoxy embraces the very general idea that the business of the visual system is to (...) create a detailed replica of the visual world, and that it accomplishes its business via hierarchical organization and by operatingessentiallyindependently of other sensorymodalitiesas well as independently of previous learning, goals, motor planning, and motor execution.

In its treatment of the role of emotion in ethics the argument of the book outlines a new way of packing motivational force into moral meaning that allows for a ...

Psychopaths are agents who lack the normal capacity to feel moral emotions (e.g. guilt based on empathy with the victims of their actions). Evidence for attributing psychopathy at least in some cases to genetic or early childhood causes suggests that psychopaths lack free will. However, the paper defends a sense in which psychopaths still may be construed as responsible for their actions, even if their degree of responsibility is less than that of normal agents. Responsibility is understood in Strawsonian terms, (...) as a question of our appropriate reactive attitudes toward an agent for what she does, and as distinct from the question of the agent's own motivating attitudes, which lead him to do what he does. The latter is the question more directly relevant to free will, though moral motivation normally depends on the capacity in early childhood to pick up motivating attitudes from others' reactive attitudes. Reactive attitudes based on hatred rather than anger (e.g. disgust or contempt) count as alternative forms of blame that may be appropriately directed toward agents manifesting bad qualities of will, even as a matter of motivational impairment. So psychopaths may still be said to deserve blame, even if they are incapable of modifying their behavior in response to blame. (shrink)

States of the brain represent states of the world. A puzzle arises when one learns that at least some of the mind/brain’s internal representations, such as a sensation of heat or a sensation of red, do not genuinely resemble the external realities they allegedly represent: the mean kinetic energy of the molecules of the substance felt (temperature) and the mean electromagnetic reflectance profile of the seen object (color). The historical response has been to declare a distinction between objectively real properties, (...) such as shape motion and mass, and merely subjective properties, such as heat, color and smell. This hypothesis leads to trouble. A challenge for cognitive neurobiology is to characterize, in suitably general terms, the nature of the relationship between brain models and the world modeled. We favor the hypothesis that brains develop high-dimensional maps whose internal relations correspond in varying degrees of fidelity to the enduring causal structure of the world. From this perspective, the basic epistemological relation is not “single-percept to single- external-feature” but rather “background-brain-maps to causal-domain-portrayed. (shrink)

Having a decreased sense of security leads to unnecessary suffering and distress for patients. Establishing trust is critical for nurses to promote a patient's sense of security, consistent with trauma‐informed care. Research regarding nursing action, trust, and sense of security is wide‐ranging but fragmented. We used theory synthesis to organize the disparate existing knowledge into a testable middle‐range theory encompassing these concepts in hospitals. The resulting model illustrates how individuals are admitted to the hospital with some predisposition to trust or (...) mistrust the healthcare system and/or personnel. Patients encounter circumstances increasing their emotional and/or physical vulnerability to harm, leading to experiences of fear and anxiety. Without intervention, fear and anxiety lead to a decreased sense of security, increased distress, and suffering. Nurse action can ameliorate these effects by increasing a hospitalized person's sense of security or by promoting the development of interpersonal trust, also leading to an increased sense of security. Increased sense of security results in diminished anxiety and fear, and increased hopefulness, confidence, calm, sense of value, and sense of control. The consequences of a decreased sense of security are harmful to patients and nurses should know that they can intervene in ways that both increase interpersonal trust and sense of security.

Why hasn’t the Marx-inspired Left seized upon catastrophic climate change as the basis for reconceiving historical materialism and the contradictions fueling anticapitalist struggle in the twenty-first century? Defining core participants as energy users and abusers, anchored in the opposition to fossil-fueled profit and growth rather than in traditional class conflicts, the struggle to create a postcapitalist energy commons can become the leading edge of a more broadly conceived global struggle for a sustainable and just postcapitalist society. The new global movement (...) will be enabled by technologies of green energy microproduction, an energy internet for sharing energy on postcapitalist grids, and efforts to create more sustainable community relationships and practices. Catastrophic climate change can become the occasion for reigniting a Marx-inspired sense of transformative agency and solidarity that will enable us to confront transnational capitalism globally and locally in ways that are beyond the imaginative bounds of the current paper.

I was led to this clarificatory job initially by some puzzlement from a philosopher's standpoint about just why free will questions should come up particularly in connection with the genome project, as opposed to the many other scientific research programs that presuppose determinism. The philosophic concept of determinism involves explanation of all events, including human action, by prior causal factors--so that whether or not human behavior has a genetic basis, it ultimately gets traced back to _something_ true of the world (...) before our birth. The philosophic problem of free will and determinism arises because this seems to undercut moral responsibility: How can we reasonably be held responsible for something whose causes we couldn't control?

There seems to be evidence of a genetic component in criminal behavior. It is widely agreed not to be "deterministic"--by which discussions outside philosophy seem to mean that by itself it is not sufficient to determine behavior. Environmental factors make a decisive difference--for that matter, there are nongenetic biological factors--in whether and how genetic.

Popular and scientific accounts of the U.S. Human Genome Project often express concern about the implications of the project for the philosophic question of free will and responsibility. However, on its standard construal within philosophy, the question of free will versus determinism poses no special problems in relation to genetic research. The paper identifies a variant version of the free will question, free will versus internal constraint, that might well pose a threat to notions of individual autonomy and virtue in (...) connection with genetic research. Whether it does depends on the extent to which the genetic basis for behavior turns on behavioral incapacities. (shrink)
