What Is and Why Do We Need Philosophy of Physics?

Philosophy of physics is a small but thriving research field situated at the intersection between the natural sciences and the humanities. However, what exactly distinguishes philosophy of physics from physics is rarely made explicit in much depth. We provide a detailed analysis in the form of eleven theses, delineating both the nature of the questions asked in philosophy of physics and the methodology with which they are addressed.     

Response: How Do We Know What We Know About the Amish and Other Minorities?

The appraisal by Cory Anderson, Joseph Donnermeyer, Jeffrey Longhofer, and Steven Reschly (hereafter, appraisers) highlights a methodological divide that is important to the study of the Amish and other ethnic or religious minorities. In my reply, I discuss how my work is rooted in a cultural analytic paradigm that differs from the appraisers’ methodological orientation. My reply includes a deconstruction of the appraisal and a discussion of its “shortcomings.” I conclude by showing how the discourse surrounding this appraisal raises important epistemological questions of how we understand human societies.     

Coparenting Interventions for Fragile Families: What Do We Know and Where Do We Need To Go Next?

With a large and growing share of American families now forming outside of marriage, triangular infant–mother–father relationship systems in “fragile families” have begun to attract the interest of family scholars and clinicians. A relatively novel conceptualization has concerned the feasibility of intervening to support the development of a sustained and positive coparenting alliance between mothers and fathers who have not made an enduring relationship commitment to one another. At this point in time, there are very few published outcome studies of programs explicitly conceived to help build coparenting alliances in such families. This article reviews what we currently know from this evolving field of study, and from those related responsible fatherhood and marriage and relationship enhancement (MRE) initiatives that included any explicit targeting, strengthening, and assessment of fragile family coparenting in their designs. We summarize lessons learned thus far from Access and Visitation (AV) programs for non‐residential fathers, from MRE programs for low‐income, unmarried couples, and from newer programs for fragile families directly designed to target and support coparenting per se. We close with recommendations for charting this important new family process terrain.     

Why Do Theologians Need to be Scientists?

The postmodern situation has given rise to a quest for new understandings of the relationship between theology and science. Drawing illustrative material from an episode of Star Trek: Voyager, I look at three paradigmatic answers to the questionn posed in the title—th modern empirical scientific, the renewed medieval, and the post-modern—with the goal of outlining a methodological approach for an engagement between Christian theology and sciencein the post-modern context. Drawing insight from post-empirical philosophy of science and the sociology of knowledge, I argue that both science and theology engage in the task of constructing a world for human habitation.     

Do We Need Grounding?

Many have been tempted to invoke a primitive notion of grounding to describe the way in which some features of reality give rise to others. Jessica Wilson argues that such a notion is unnecessary to describe the structure of the world: that we can make do with specific dependence relations such as the part–whole relation or the determinate–determinable relation, together with a notion of absolute fundamentality. In this paper I argue that such resources are inadequate to describe the particular ways in which some parts of reality give rise to others, and thus that we do in fact need grounding.     

What Do We Know About Gay and Lesbian Couples?

Abstract— Research on gay and lesbian couples is highlighted with regard to household labor, conflict, satisfaction, perceived social support, stability, and the variables that predict relationship quality. Relative to partners from married heterosexual couples, partners from gay and lesbian couples tend to assign household labor more fairly, resolve conflict more constructively, experience similar levels of satisfaction, and perceive less support from family members but more support from friends. The limited data available indicate that gay and lesbian couples may be less stable than married heterosexual couples. The factors that predict relationship quality tend to be the same for gay, lesbian, and heterosexual married couples. Overall, research paints a positive picture of gay and lesbian couples and indicates that they tend to be more similar to than different from heterosexual couples.     

Integrity and Honesty Testing: What Do We Know? How Do We Use It?

This selective review of integrity and honesty testing addresses two primary questions: ‘What do we know about honesty testing?’ and ‘How do we use what we know?’ Up-to-date information about test reliability, validity, and construct definition from recent reviews of the research literature in the USA is presented and interpreted. Relationships to other selection devices and personality measures are discussed, as well as how integrity tests fit into a multiple assessment selection system.     

What Do We Know About Neuropsychological Aspects Of Schizophrenia?

Application of a neuropsychological perspective to the study of schizophrenia has established a number of important facts about this disorder. Some of the key findings from the existing literature are that, while neurocognitive impairment is present in most, if not all, persons with schizophrenia, there is both substantial interpatient heterogeneity and remarkable within-patient stability of cognitive function over the long-term course of the illness. Such findings have contributed to the firm establishment of neurobiologic models of schizophrenia, and thereby help to reduce the social stigma that was sometimes associated with purely psychogenic models popular during parts of the 20th century. Neuropsychological studies in recent decades have established the primacy of cognitive functions over psychopathologic symptoms as determinants of functional capacity and independence in everyday functioning. Although the cognitive benefits of both conventional and even second generation antipsychotic medications appear marginal at best, recognition of the primacy of cognitive deficits as determinants of functional disability in schizophrenia has catalyzed recent efforts to develop targeted treatments for the cognitive deficits of this disorder. Despite these accomplishments, however, some issues remain to be resolved. Efforts to firmly establish the specific neurocognitive/neuropathologic systems responsible for schizophrenia remain elusive, as do efforts to definitively demonstrate the specific cognitive deficits underlying specific forms of functional impairment. Further progress may be fostered by recent initiatives to integrate neuropsychological studies with experimental neuroscience, perhaps leading to measures of deficits in cognitive processes more clearly associated with specific, identifiable brain systems.     

Aging and Spatial Navigation: What Do We Know and Where Do We Go?

Spatial navigation is a complex cognitive skill that is necessary for everyday functioning in the environment. However, navigational skills are not typically measured in most test batteries assessing cognitive aging. The present paper reviews what we know about behavioral differences between older and younger adults in navigational skill and reviews the putative neural mechanisms that may underlie these behavioral differences. Empirical studies to date clearly identify navigation as an aspect of cognitive function that is vulnerable to the aging process. The few functional and structural neuroimaging studies that speak to neurological correlates of these age-related differences point to the hippocampus, parahippocampal gyrus, posterior cingulate gyrus (retrosplenial cortex), parietal lobes and pre-frontal cortex as structures critically involved in age effects on navigation. Outstanding issues in the field are addressed and productive avenues of future research are suggested. Among these outstanding issues include the necessity of performing longitudinal studies and differentiating between hippocampal and extra-hippocampal contributions to aging in navigation. The field may also be advanced by empirical assessment of navigational strategies and investigations into the multisensory nature of navigation including assessing the relative contributions of visual, vestibular, and proprioceptive function to age differences in navigational skill.
