A Four-fold Strategy for Training Parents to Teach Spiritual Formation at Home
The purpose of this project is to aid church leaders toward understanding the dynamics of family ministry: what it is and what it is not. Having written five books for Focus on the Family and David C. Cook addressing the role of the church and family, this author has successfully transitioned his church from the traditional family ministry (families in the support role of the church) to placing the church in the support role of the family: strengthening God\u27s family by strengthening theirs. Based on surveys, evaluations of each individual family\u27s health, historical and cultural documents, resources, and actual case studies, this thesis will delineate the principles and strategies that have proven effective for driving faith home. The church should then be effective in implementing a sustained ministry to parents who are intentionally passing their faith to their children
Wheat and Tares: Responding to Vande Kemp and other Revisionists
In her reaction, Hendrika Vande Kemp ( 1987) joins other critics of psychology in arguing for a new psychology. The authors believe, however, that psychology developed as a science because it was productive and that more subjective methods will gain respectability only through similar productivity. In her critique, Vande Kemp creates a circular argument by suggesting that the authors\u27 position Jacks a proper historicaVphilosophical perspective, and she underestimates the sophistication of those with whom she disagrees. Finally, the authors disagree that there is no point in arguing with the most conservative anti-psychologists, since they may be having a disproportionate influence on public perceptions of psychology
Small-sized dichroic atomic vapor laser lock
Two, lightweight diode laser frequency stabilization systems designed for
experiments in the field are described. A significant reduction in size and
weight in both models supports the further miniaturization of measurement
devices in the field. Similar to a previous design, magnetic-field lines are
contained within a magnetic shield enclosing permanent magnets and a Rb cell,
so that these DAVLL systems may be used for magnetically sensitive instruments.
The Mini-DAVLL system (49 mm long) uses a vapor cell (20 mm long), and does not
require cell heaters. An even smaller Micro-DAVLL system (9mm long) uses a
micro-fabricated cell (3 mm square), and requires heaters. These new systems
show no degradation in performance with regard to previous designs, while
considerably reducing dimensions.Comment: 13 pages, 11 figures, published versio
Itk Negatively Regulates Induction of T Cell Proliferation by CD28 Costimulation
CD28 is a cell surface molecule that mediates a costimulatory signal crucial for T cell proliferation and lymphokine production. The signal transduction mechanisms of CD28 are not well understood. Itk, a nonreceptor protein tyrosine kinase specifically expressed in T cells and mast cells, has been implicated in the CD28 signaling pathway because of reports that it becomes phosphorylated on tyrosines and associates with CD28 upon cross-linking of the cell surface molecule. To determine whether Itk plays a functional role in CD28 signaling, we compared T cells from Itk-deficient mice and control mice for their responses to CD28 costimulation. T cells defective in Itk were found to be fully competent to respond to costimulation. Whereas the CD3-mediated proliferative response was severely compromised in the absence of Itk, the calcineurin-independent CD28-mediated response was significantly elevated when compared with cells from control animals. The augmented proliferation was not due to increased production of interleukin-2. The results suggest that Itk has distinct roles in the CD3 versus the CD28 signaling pathways. By negatively regulating the amplitude of signaling upon CD28 costimulation, Itk may provide a means for modulating the outcome of T cell activation during development and during antigen-driven immune responses
Toward the Elucidation of Cytoplasmic Diversity in North American Grape Breeding Programs
Plants have an intriguing tripartite genetic system: Nuclear genome 9 Mitochondria 9 Plastids and their interactions may impact germplasm breeding. In grapevine, the study of cytoplasmic genomes has been limited, and their role with respect to grapevine germplasm diversity has yet to be elucidated. In the present study, the results of an analysis of the cytoplasmic diversity among 6073 individuals (comprising cultivars, interspecific hybrids and segregating progenies) are presented. Genotyping by sequencing (GBS) was used to elucidate plastid and mitochondrial DNA sequences, and results were analyzed using multivariate techniques. Single nucleotide polymorphism (SNP) effects were annotated in reference to plastid and mitochondrial genome sequences. The cytoplasmic diversity identified was structured according to synthetic domestication groups (wine and raisin/table gr.ape types) and interspecific-hybridization-driven groups with introgression from North American Vitis species, identifying five cytoplasmic groups and four major clusters. Fifty-two SNP markers were used to describe the diversity of the germplasm. Ten organelle genes showed distinct SNP annotations and effect predictions, of which six were chloroplast-derived and three were mitochondrial genes, in addition to one mitochondrial SNP affecting a nonannotated open reading frame. The results suggest that the application of GBS will aid in the study of cytoplasmic genomes in grapevine, which will enable further studies on the role of cytoplasmic genomes in grapevine germplasm, and then allow the exploitation of these sources of diversity in breeding

Site 503: Eastern Equatorial Pacific
Our primary objective at Site 503 (Fig. 1) was to re- cover a complete, undisturbed Neogene and Quaternary section in the eastern equatorial Pacific. Site 503 is located near Site 83 in an area that contains an almost continuous pelagic record of the past 10 m.y. (Hays et al., 1972). Unfortunately, Site 83 was only spot-cored, and the recovered sediment is so badly disturbed by rotary drilling that most of the detailed record is lost. The section has an average sedimentation rate of 2.0 to 2.5 cm/k.y. with good-to-moderate preservation of all the major microfossil groups. We returned to Site 83 to core the same section, using the Hydraulic Piston Corer (HPC) to obtain an undisturbed, continuous section for high-resolution stratigraphic studies

Site 502: Colombia Basin, Western Caribbean
Our specific objective at Site 502 was to recover an undisturbed, complete section that could be used as a Neogene and Quaternary reference section. A complete record such as this would allow intercorrelations between (1) paleomagnetic stratigraphy, (2) calcareous biostratigraphy, (3) cyclic accumulation of sediment, (4) paleoceanographic changes, (5) oxygen and carbon isotope stratigraphies, (6) the chronology of Central American volcanism, (7) the timing and effects of the emergence of the Isthmus of Panama, and (8) the timing and effects of the initiation of Northern Hemisphere glaciation
Spaghetti Shakespeare: Johnny Hamlet and the Italian Western
The Italian Western, Johnny Hamlet (1968), directed by Enzo G. Castellari, draws on the revenge story of Shakespeare’s tragedy Hamlet for plot and characterization. While international distributors of the film downplayed its connection to highbrow Shakespeare, they emphasized the movie’s violent content and action-packed revenge narrative, which was typical of the western all’italiana. Johnny Hamlet shares similarities with the brutally violent Django (1966), directed by Sergio Corbucci, whose avenging angel protagonist epitomizes the Spaghetti Western antihero. Although the filmmakers of Johnny Hamlet characterized Johnny as a vindicator, they also sought to develop the “broody” aspect of this gunfighter, one based on Shakespeare’s famously ruminating hero. Using innovative film techniques, Johnny Hamlet shows Johnny as a contemplative pistolero
