"Biodiversity prospecting" has been touted as a mechanism for both discovering new pharmaceutical products and saving endangered ecosystems. It is unclear what values may arise from such activities, however. Evidence from transactions is incomplete and existing theoretical models are flawed. We calculate an upper bound on the value of the "marginal species." Even under favorable assumptions this bound is modest. Slightly modified assumptions lead to drastically lower estimates. We extend our findings to the value of the marginal hectare of habitat (...) and find that the incentives for habitat conservation generated by private pharmaceutical research are also, at best, very modest.

An important application of cognitive architectures is to provide human performance models that capture psychological mechanisms in a form that can be “programmed” to predict task performance of human–machine system designs. Although many aspects of human performance have been successfully modeled in this approach, accounting for multitalker speech task performance is a novel problem. This article presents a model for performance in a two-talker task that incorporates concepts from psychoacoustics, in particular, masking effects and stream formation.

The concept of ‘causal powers’ as principles of necessary change, once derided by mainstream philosophers in the thrall of David Hume, has made a dramatic comeback and seems to be here to stay. The...

This work is primarily concerned with Hume's arguments concerning the respective roles of reason and passion in moral decisions. Thus, the major part of the work deals with section I of Part I of Book III of the Treatise, where Hume argues that moral distinctions are not derived from reason. But in discussing this section, I have had to take into account most ofthe other sections of Book III, and some important ones from Book II of the Treatise and the (...) Enquiry Concerning the Principles of Morals. Omissions, however, are noticeable. While I have gone into great detail on Parts I and II ofthe Treatise of Morals, I have omitted any discussion of Part III. I have not discussed everything Hume has to say on ethics, or even everything in Book III of the Treatise. I have placed certain limits on myself in writing this work. I attempt to point out only what is central to Hume's ethics, and this I believe to be the first section of Book III, and to show how certain assumptions and conclusions of this section underlie the rest of Hume's considerations on ethics. Thus, I have tried to show that Hume's discussion of the artificial virtues necessarily follows from the assump tions and conclusions of section I. But I leave it to the reader, in his further study of Hume, to apply my points to other sections of Hume that I have not discussed. (shrink)

This article focuses on Bretherton’s treatment of Pentecostalism and Black Power and how they conceive and challenge notions of democracy, citizenship and capitalism. Recognising the ‘tensional’ relationship between democracy and Christianity, I explore his treatment of Pentecostalism and capitalism. I am sympathetic to Bretherton’s analysis of the socio-political transformation Pentecostalism offers, but point to regressive influences associated with the ‘prosperity gospel’. Relating his treatment of Black Power to the wider ‘Black radical tradition’, I conclude with reference to political activism in (...) the UK. (shrink)

The Gauḍīya Vaiṣṇava tradition emerged within the context of Muslim political dominance in Bengal. As such, perceptions of Muslims embedded within Gauḍīya literature are part and parcel of their worldview. Muslims, however, have to construct perceptions of Gauḍīya Vaiṣṇavas from the ground up, utilizing scriptural references emerging in a distinctively different milieu and putting them into conversation with scholarly methodologies for cross-cultural engagement. This paper articulates a contemporary method for Muslim engagement with Gauḍīya Vaiṣṇavas that is rooted in a decolonial (...) solidarity of respect for the internal logics of religious traditions.

Research indicates that positive relationships with fellow church members are associated with better mental health. However, far less research has focused on the relationship between negative interaction with fellow church members and mental health outcomes. The purpose of this study is to examine the relationship between church-based negative interaction and depressive symptoms with data from a nationwide sample of older Mexican Americans. Statistically significant findings were found for the following core relationships in our study model: older Mexican Americans who encounter (...) negative interaction with fellow church members experience more doubts about their faith; older Mexican Americans who experience more doubts about their faith are more likely to expect transgressors to perform acts of contrition ; and older Mexican Americans who require transgressors to perform acts of contrition are more likely to experience symptoms of depression. Subsequent empirical analyses provide support for each of these relationships. (shrink)

Some researchers maintain that one of the primary functions of religion is to help individuals develop a strong sense of connectedness with other people. However, there is little research on how a sense of connectedness arises. The purpose of this study is to examine this issue. A conceptual model is developed to test the following key hypotheses: blacks are more likely than whites to affiliate with Conservative Christian denominations; Conservative Christians attend worship services more often than individuals in other faith (...) traditions; people who go to church more often are more likely to receive informal spiritual support ; individuals who receive more spiritual support are more likely to read religious literature and watch or listen to religious programs; and people who engage in these private religious practices are more likely to feel a close sense of religiously based connectedness with others. Data from a nationwide longitudinal survey provides support for each hypothesis. (shrink)

The purpose of this study is to assess the relationship between involvement in three aspects of congregational life and spiritual growth. In addition, an effort is made to see if spiritual growth may, in turn, affect health. A latent variable model was developed to test the following hypotheses: individuals who attend worship services more often, attend Bible study and prayer group meetings more frequently, and individuals who receive more spiritual support from fellow church members will be more likely to report (...) they have experienced spiritual growth; people who experience more spiritual growth will be more likely to derive a deeper sense of meaning in life; and individuals who have developed a deeper sense of meaning in life will enjoy better health. Data from the U.S. Congregational Life Survey suggests that spiritual support has the stronger relationship with spiritual growth than either worship service attendance or involvement in formal church groups. The findings further reveal that greater spiritual growth is associated with a deeper sense of meaning in life and meaning, in turn, is associated with better health. (shrink)

The fourteen authors in this collection used phenomenology and hermeneutics to conduct deep inquiry into perplexing and wondrous events in their work and personal lives. These seasoned scholar-practitioners gained remarkable insight into areas such as health care and illness, organ donation, intercultural communications, high-performance teams, artistic production, jazz improvisation, and the integration of Tai Chi into education. All authors were transformed by phenomenology's expanded ways of seeing and being.

Do dissociations imply independent systems? In the memory field, the view that there are independent implicit and explicit memory systems has been predominantly supported by dissociation evidence. Here, we argue that many of these dissociations do not necessarily imply distinct memory systems. We review recent work with a single-system computational model that extends signal-detection theory (SDT) to implicit memory. SDT has had a major influence on research in a variety of domains. The current work shows that it can be broadened (...) even further in its range of application. Indeed, the single-system model that we present does surprisingly well in accounting for some key dissociations that have been taken as evidence for independent implicit and explicit memory systems.

The wave function of quantum mechanics can be understood in terms of the dispositional role it plays in the dynamics of a distribution of matter in three-dimensional space (or four-dimensional spacetime). There is more than one way, however, of specifying its dispositional role. This paper considers Suárez’s theory of ‘Bohmian dispositionalism’, in which the particles are endowed with their own ‘Bohmian dispositions’, and Simpson’s theory of ‘Cosmic Hylomorphism’, in which the particle configuration comprises a hylomorphic substance which has an (...) intrinsic power. I argue that Bohmian dispositionalism fails to capture intuitively correct counterfactuals about what would happen in Small Worlds which have only a small number of particles, but that this problem is avoided by Cosmic Hylomorphism, in which the cosmic power manifests a teleological process.

The third section considers the relevance of Levinas's work for reassessments of the realist novel through essays on Austen, Dickens, and George Eliot.

Three- to six-year-olds were given Heyes's proposed task and theory of mind tasks. Although they correlated, Heyes's was harder; only 50% of participants with a theory of mind reached a criterion of 75% correct. Because of the complex series of inferences involved in Heyes's task, it is possible that one could have a theory of mind and fail Heyes's version.
