Conclusion While Kripke's original paper on the theory of truth used a three-valued logic, we believe a four-valued version is more natural. Its use allows for possible inconsistencies in information about the world, yet contains Kripke's development within it. Moreover, using a four-valued logic makes it possible to work with complete lattices rather than complete semi-lattices, and thus the mathematics is somewhat simplified. But more strikingly, the four-valued version has a wide, natural generalization to the family of interlaced bilattices. Thus, with little more work, the theory is extended to a broad class of settings. Indeed, a result like Theorem 6.2 would not even be possible to state without the interlaced bilattice machinery. We hope the notion of interlaced bilattice will make apparent further such connections.  相似文献

Abstract. The idea of a text is reviewed and reconstructed to facilitate the application of concepts of interpretation to the objects analyzed in the natural sciences, as well as to objects analyzed in religion and literature. Four criteria—-readability, formality, material transcendence, and retrievability—-are proposed as the basis for a generalized conception of text. Objects in both religion and science, not previously thought to be texts, are shown to be included in the new definition and therefore to be potential subjects of developing methods of interpretation.  相似文献

Abstract. The roots of religious faith–and the provenance of ethical thought–may be sought in the human sciences, the physical sciences, literature, religious traditions, and deep human intuitions. Gustafson's religious stance and the author's, while different on their face, in common reflect a mingling–and tangling–of skepticism, understanding, and transcendence. Let all of us hope and believe what we can.  相似文献

We investigated the relationship between parental influences and academic outcomes for African-American students. Secondary data analysis was conducted on the National Survey of Family and Household data set. Multiple regression analysis showed that parenting style (nurture and control) and parental involvement significantly predicted academic outcomes. Research has traditionally focused on the reasons for the failure of African-American students to succeed in school. This study focused on factors that determine success. The problem of negative school outcomes may be alleviated by studying what works to promote school success rather than what does not work for African-American students.  相似文献

Traditional genetic counseling processes and principles will be extended to a new realm—complex disorders. Although it may seem like a daunting task, understanding the methodologies used to study complex genetic disorders will enable genetic counselors to critically analyze research studies involving complex disorders. In this article, we explain newly evolving methodologies for genetic research, including case-control studies and transmission disequilibrium testing (TDT). Additionally, a framework is provided for evaluating original research findings and replication studies.  相似文献

Tested the effectiveness of a youth drug prevention program in a community setting. Boys & Girls Clubs of America's Stay SMART program, adapted from a school-based personal and social competence drug prevention program, was offered, with and without a 2-year booster program, to 13-year-old members of Boys & Girls Clubs. Over 27 months, (a) 5 Boys & Girls Clubs offered the Stay SMART program, (b) 5 Boys & Girls Clubs offered the Stay SMART program with the booster programs, and (c) 4 Boys & Girls Clubs served as a control group. The Stay SMART program alone and the Stay SMART program with the booster programs showed effects for marijuana-related behavior, cigarette-related behavior, alcohol-related behavior, overall drug-related behavior, and knowledge concerning drug use. The Stay SMART program with the booster programs produced additional effects for alcohol attitudes and marijuana attitudes after each year of booster programs. Results suggest that a school-based personal and social competence program can be adapted effectively to a community setting and that booster programs might enhance program effects. Implications for alternative community models of prevention are discussed. At the time of the study, the parent organization was Boys Clubs of America.This research was supported by a grant from the Office for Substance Abuse Prevention, ADAMHA, Public Health Service, Department of Health and Human Services, Grant No. 1 H84 AD 00903-01.  相似文献

The paper outlines an expansion of object relations theory to account for fragmentation and shame. This expansion promotes a better psychodynamic perspective on the type of marital conflict escalation that occurs when each spouse turns to the other for empathic receptiveness while that other is also in a disorganized and vulnerable state of mind. Escalation occurs when spouses have different needs for safety and optimum distance and when the shame generated by continued exposure of these needs is not acknowledged. Clinical precepts promoting a focus on fragmentation and acknowledgement of shame are elaborated.  相似文献

With the increasing number of Black mothers participating in the labor force, rearing children without fathers present, and relying on extended family for support the question of the nature of role-flexibility and sharing in the family is raised. Sixty-four families participated in an examination of the relative influence of one- and two-parent Black families and the proximity of the grandmother on self-report measures of (a) household maintenance duties, (b) childcare duties, and (c) parental punishment behaviors. Parents, grandmothers, and at least one child between the ages of 7 and 14 years completed three types of self-report measures. Although the results indicated that mothers, fathers, and grandmothers were nominated as consistently participating in childcare and household maintenance duties, mothers were nominated for more than 60% of the childcare and household tasks. Moreover mothers and not fathers used the full range of discipline practices including corporal punishment. The hypothesis regarding role-sharing in Black household was not supported. Black mothers, like mothers in general, are primarily responsible for the maintenance of the house and the care of children.The preparation of this review was supported by Carter G. Woodson Institute for Afro-American and African Studies, National Science Foundation Grant PRM-8210411, Rockefeller and Spencer Foundations grants.  相似文献
