The concept of "fitness" is a notion of central importance to evolutionary theory. Yet the interpretation of this concept and its role in explanations of evolutionary phenomena have remained obscure. We provide a propensity interpretation of fitness, which we argue captures the intended reference of this term as it is used by evolutionary theorists. Using the propensity interpretation of fitness, we provide a Hempelian reconstruction of explanations of evolutionary phenomena, and we show why charges of circularity which have been levelled (...) against explanations in evolutionary theory are mistaken. Finally, we provide a definition of natural selection which follows from the propensity interpretation of fitness, and which handles all the types of selection discussed by biologists, thus improving on extant definitions.

The only study of de Lubac that interprets his theology through the categories of medieval exegesis, this volume shows that the principles of spiritual exegesis provided de Lubac with the intellectual tools for thinking about a theology of history, a theology of symbol and sacrament, and a theology of the church's relationship to Christ and the Eucharist.

Unpublished counts of larceny arrests and census data for five of the largest cities in the United States are used to examine the contribution of white and nonwhite men and women in specific age groups to increases in larceny arrests from 1960 to 1980. The results suggest that nonwhite women and white men now have similar larceny arrest rates and that 77 percent of the total increase in the arrest of women for larceny from 1960 to 1980 was the result (...) of increased arrests of nonwhite women. Although 18 percent of this increase can be explained by increased numbers of nonwhite women in specific age groups in the population, the worsening economic situation of young black women in older U.S. central cities is suggested as the most plausible explanation for these trends. Implications of the findings for other theories of women's criminality are examined. (shrink)

Passionate readers both, Olivia Langdon and Mark Twain courted through books, spelling out their expectations through literary references as they corresponded during their frequent separations. Surprisingly, in the process Olivia Langdon reveals herself not as a hypochondriacal hysteric, as many twentieth-century critics have portrayed her, but as a thoughtful intellectual, widely read in literature, history and modern science. Not so surprisingly, Samuel Clemens reveals himself as a critic and a sceptic, lampooning Langdon's physics lessons and her literary heroines. He also (...) shows himself as an astute strategist, carefully manipulating Langdon and her parents. At the same time, Clemens's letters exhibit his own conservatism about women's nature and women's roles, while Langdon's show her carefully choosing from her culture's array of possible role models.

The more than fifty years of dialogue since Vatican II launched the Catholic Church into the ecumenical movement have resulted in significant convergence, but reception of these results remains slow and inconclusive despite the stunning success of the Joint Declaration on Justification signed in 1999. This presentation explores some of the challenges for reception within the ecclesial and social context of ecumenical relationships today and discusses why the ecumenical imperative is even more critical at this point in time. It also (...) suggests a model of ecclesiology for the reception of relationships of full communion. (shrink)

Although research has found that long-term mindfulness meditation practice promotes executive functioning and the ability to sustain attention, the effects of brief mindfulness meditation training have not been fully explored. We examined whether brief meditation training affects cognition and mood when compared to an active control group. After four sessions of either meditation training or listening to a recorded book, participants with no prior meditation experience were assessed with measures of mood, verbal fluency, visual coding, and working memory. Both interventions (...) were effective at improving mood but only brief meditation training reduced fatigue, anxiety, and increased mindfulness. Moreover, brief mindfulness training significantly improved visuo-spatial processing, working memory, and executive functioning. Our findings suggest that 4 days of meditation training can enhance the ability to sustain attention; benefits that have previously been reported with long-term meditators. (shrink)

This article seeks to overcome some of the greatest difficulties in generating a feminist-friendly approach to sacraments by proposing a new paradigm: sacraments as forms of energy. Several factors have hindered feminist theologians in revisioning sacramentality. For the most part sacraments were ‘done to’ women, never ‘done by’ women. A too-literal reading of the Christian scriptures blurs the fact that early Christians developed ritual patterns for Baptism and Eucharist first, and only later wrote them down. To speak of sacraments as (...) mediations may re-inscribe dualism. The static model of reality which explained sacraments in Aristotelian categories of matter and form has given way to dynamic models of matter and energy. A sacramentality of energy can be articulated from three different angles: first, in terms of the action of the Holy Spirit; second, from scientific advances in quantum thinking, and the third from new spirituality. This paradigm applies to both Baptism and Eucharist. (shrink)

Allen Carlson has argued that a proper aesthetics of nature must judge nature for ‘what it is’, and that such judgements must be informed by a scientific understanding of nature, in particular, one shaped by the science of ecology. Carlson uses these claims to support his theory of positive aesthetics. This paper argues that there are problems in this view. First, it misunderstands ecology, thereby adopting a view of the natural world that holds it to be much more integrated than (...) it is. Second, it ignores an even more fundamental science of nature, evolution. Thus, it misunderstands both ecology and nature. An alternative to this view would be an aesthetics based on an evolutionary understanding of nature, which holds that, although there are many functional wholes in nature, there is also significant conflict, disintegration, and incongruent scales. A proper aesthetics of nature must take these conflicts into account. The paper ends with a sketch of an aesthetic theory based on the science of evolution. (shrink)

Beginning with Ronald Hepburn’s path-breaking essay, “Contemporary Aesthetics and the Neglect of Natural Beauty,” which helped establish the modern discipline of environmental aesthetics, philosophers have provided sketches of what, after Hegel, might be called “philosophical histories of the aesthetics of nature.” These histories are remarkably similar and can easily be blended together to create a “received history” of the discipline. This history has subtly influenced work in the field. Unfortunately, it is not completely accurate and, as a result, has had (...) a misleading effect. A more accurate and expanded alternative history calls into question the received history’s view both on the origins of the field in arts-based aesthetic theories and on the nature and value of the aesthetic categories, “the picturesque” and “the sublime.” These categories were not borrowed from philosophy of art and inappropriately applied to nature, but instead were developed to appraise landscapes, which unlike natural objects could only rarely be judged beautiful since they are almost never symmetrical or ordered.

More than two decades after the passage of the Civil Rights Act of 1964, the issues of racial discrimination and affirmative action are still matters of controversy. The fragile national consensus on civil rights policy has been increasingly fragmented by resistance and confusion in recent years, especially under the impact of the Reagan administration's efforts to change its direction dramatically. Similarly, since the mid-1960s, the women's rights movement has worked to end discrimination and bring about greater equality for women in (...) employment and public life. Yet, recent years have witnessed increased national ambivalence about these goals and how they should be achieved, especially on the issue of comparable worth. (shrink)

The use of high hypothetical payoffs has been justified by the realism and relevance of large monetary consequences and by the impracticality of making high cash payments. We argue that subjects may not be able to imagine how they would behave in high payoff situations.

The impact of stress and other psychological variables on Inflammatory Bowel Disease prognosis, treatment response, and functional level is well-established; however, typical IBD treatment focuses on the physiological pathology of the disease and neglects complementary stress-reducing interventions. Recent pilot studies report the benefits of mindfulness-based interventions in people living with IBD, but are limited by small sample sizes. Recruitment challenges to in-person studies may be in part due to the difficulty IBD patients often have adhering to fixed schedules and travel (...) as a result of IBD symptoms such as pain, fatigue, and incontinence. The current study aimed to address this barrier by offering participants access to online mindfulness training, allowing individuals to engage with intervention materials to fit their own schedule. Online mindfulness programs have gained popularity in recent years, as they increase access and flexibility and decrease cost to the user; however, the dropout rate tends to be high. The current study compared the rate of adherence and efficacy of mindfulness training as a function of level of support: self-guided versus supported. Analysis revealed no significant difference in the benefits received between participants in the two groups; however, a significant difference group was found in terms of rate of completion, with 44.1% of the supportive group completing the protocol compared to 11.7% of the self-guided. Common challenges to meditation were measured, but did not significantly predict adherence to the intervention, and experience of these challenges did not significantly change over the duration of the study. Implications of the current research, future directions for the use of MBI for IBD patients, and a discussion of methodological considerations are provided. (shrink)

Studies of the association between wealth and fertility in industrial populations have a rich history in the evolutionary literature, and they have been used to argue both for and against a behavioral ecological approach to explaining human variability. We consider that there are strong arguments in favor of measuring fertility (and proxies thereof) in industrial populations, not least because of the wide availability of large-scale secondary databases. Such data sources bring challenges as well as advantages, however. The purpose of this (...) article is to illustrate these by examining the association between wealth and reproductive success in the United States, using the National Longitudinal Study of Youth 1979. We conduct a broad-based exploratory analysis of the relationship between wealth and fertility, employing both cross-sectional and longitudinal approaches, and multiple measures of both wealth (income and net worth) and fertility (lifetime reproductive success and transitions to first, second and third births). We highlight the kinds of decisions that have to be made regarding sample selection, along with the selection and construction of explanatory variables and control measures. Based on our analyses, we find a positive effect of both income and net worth on fertility for men, which is more pronounced for white men and for transitions to first and second births. Income tends to have a negative effect on fertility for women, while net worth is more likely to positively predict fertility. Different reproductive strategies among different groups within the same population highlight the complexity of the reproductive ecology of industrial societies. These results differ in a number of respects from other analyses using the same database. We suggest this reflects the impossibility of producing a definitive analysis, rather than a failure to identify the “correct” analytical strategy. Finally, we discuss how these findings inform us about (mal)adaptive decision-making. (shrink)

This co-edited volume compares Chinese and Western experiences of engineering, technology, and development. In doing so, it builds a bridge between the East and West and advances a dialogue in the philosophy of engineering. Divided into three parts, the book starts with studies on epistemological and ontological issues, with a special focus on engineering design, creativity, management, feasibility, and sustainability. Part II considers relationships between the history and philosophy of engineering, and includes a general argument for the necessity of dialogue (...) between history and philosophy. It continues with a general introduction to traditional Chinese attitudes toward engineering and technology, and philosophical case studies of the Chinese steel industry, railroads, and cybernetics in the Soviet Union. Part III focuses on engineering, ethics, and society, with chapters on engineering education and practice in China and the West. The book’s analyses of the interactions of science, engineering, ethics, politics, and policy in different societal contexts are of special interest. The volume as a whole marks a new stage in the emergence of the philosophy of engineering as a new regionalization of philosophy. This carefully edited interdisciplinary volume grew out of an international conference on the philosophy of engineering hosted by the University of the Chinese Academy of Sciences in Beijing. It includes 30 contributions by leading philosophers, social scientists, and engineers from Australia, China, Europe, and the United States. (shrink)

The Commission on the Accreditation of Law Enforcement employs rigorous evaluation techniques. Objective accreditation, such as made possible by CALEA, is important from the public’s perspective and in the national community of law enforcement.To counteract a general distrust of law enforcement agencies, the Law Enforcement Assistance Administration developed a grant to develop standards by which the quality and performance of law enforcement could be measured. LEAA developed 107 standards and, though well received by the law enforcement community, no single group (...) or agency took the initiative to begin a program to evaluate and implement the standards. In 1979, the Department of Justice established an additional grant that effectively organized the four major law enforcement groups: the International Association of Chiefs of Police, the National Sheriff’s Association, the National Organization of Black Law Enforcement Executives, and the Police Executive Research Forum.

No consensus yet exists on how to handle incidental fnd-ings in human subjects research. Yet empirical studies document IFs in a wide range of research studies, where IFs are fndings beyond the aims of the study that are of potential health or reproductive importance to the individual research participant. This paper reports recommendations of a two-year project group funded by NIH to study how to manage IFs in genetic and genomic research, as well as imaging research. We conclude that researchers (...) have an obligation to address the possibility of discovering IFs in their protocol and communications with the IRB, and in their consent forms and communications with research participants. Researchers should establish a pathway for handling IFs and communicate that to the IRB and research participants. We recommend a pathway and categorize IFs into those that must be disclosed to research participants, those that may be disclosed, and those that should not be disclosed. (shrink)
