Neuropsychological Functioning in Non-Schizophrenic First-Degree Relatives of Schizophrenics

Description: Research has consistently shown schizophrenics to perform significantly poorer than normal controls on commonly used measures of neuropsychological functioning. Research on the neuropsychological functioning of first-degree relatives of schizophrenics who do not themselves have schizophrenia is comparatively sparse but suggests the likelihood of deficits in this group as well. A battery of standard neuropsychological tests was administered to three groups: first-degree relatives of schizophreni… more

Neuropsychological Functioning of Blind Subjects with Learning Disabilities Compared to Those with Blindness Alone

Description: It has been hypothesized that a disproportionate percentage of the blind population are learning disabled. In the past, norms and technology were not available to assess in a cost effective manner the blind client's neuropsychological functioning. Norms for the Wide Range Achievement Test - Revised (WRAT-R2) are now available for a blind population without any neuropsychological dysfunctioning. This study utilized the adapted WRAT-R2 and the Comprehensive Vocational Evaluation System (CVES), a … more

Neuropsychological Sequelae of Adult Subjects with Retinopathy of Prematurity Compared to Other Blind Populations

Description: The blind have generally been considered to be a homogeneous population whose deficits arise from an interaction of loss of vision, age of onset and socialization. Sequelae are posited to exist merely due to the limiting effects of blindness on experience. This is believed to affect all blind persons equally regardless of cause of blindness provided that independent secondary disabilities do not exist. This study investigated the possibility that different causes of blindness are related to spe… more

A New Method for Measuring the Nuclear Hexadecapole Interaction in Some Solids

Description: A new method for measuring the nuclear hexadecapole interaction (HDI) in solids based on NMR quadrupole echoes is described. Theoretical values of the shifts of the quadrupole echo times caused by the HDI are given for two pulse and three pulse echoes in a nuclear spin 5/2 system. The method is applied to 1271 in an almost strain free crystal of KI and a hexadecapole coupling frequency (e2M16m16/h) of 630 Hz was found. Here e is the electronic charge, em16 is the fourth gradient of the external… more

A New Way of Statecraft: The Career of Elton Mayo and the Development of the Social Sciences in America, 1920-1940

Description: Considered "the father of the science of human relations," Elton Mayo was instrumental in the development of industrial psychology and sociology in America. The career of Elton Mayo and his attraction to influential figures like John D. Rockefeller, Jr., provide a chronological order and interpretive force to understand this development. Mayo's concern about human behavior in the modern industrial world and management's concern over the future of industrial relations, found common ground in th… more

Night of No Exile

Description: Night of no Exile is a collection of poems preceded by a critical article entitled "‘Exile seems both a blessing and a curse': A Blissful Reading of Li-Young Lee's Poetry." That article discusses Lee's quest to achieve communication, truth, and transcendence through poetic language and concludes that he finally reaches his goal through a leap from narrative poetry to lyricism. The "exile" alluded to in the title of the article is not only geographic, but also interioran exile due to the natural… more

"Nobody knows, so still it flows"—The Discourse of Water in the Poetry of Emily Dickinson

Description: Emily Dickinson's use of water as a dominant poetic trope differs from typical religious archetypal associations with baptism, cleansing, and rebirth. Dickinson transforms rather than recapitulates established theological concepts, borrowing and adapting Biblical themes to suit her artistic purposes. Dickinson's water poems are the poet's means of initiating a discourse with God. Dickinson's poems, however, portray the poet's seeking communion and finding only a silent response to her attempts … more

Node-Link Mapping and Rational Recovery: Enhancing the Recovery Process

Description: Alcoholics Anonymous (AA) continues to be the most accepted approach for the treatment of addictions in the United States. However, due to recent evidence questioning the effectiveness of AA, the need for alternative approaches to the treatment of addictions has become clear. The following research addresses the efficacy of one such alternative, Rational Recovery (RR). Node-Link Mapping (NLM), a graphic communication technique which uses links and nodes as building blocs to facilitate and enhan… more

Nonlinear Dynamics of Semiconductor Device Circuits and Characterization of Deep Energy Levels in HgCdTe by Using Magneto-Optical Spectroscopy

Description: The nonlinear dynamics of three physical systems has been investigated. Diode resonator systems are experimentally shown to display a period doubling route to chaos, quasiperiodic states, periodic locking states, and Hopf bifurcation to chaos. Particularly, the transition from quasiperiodic states to chaos in line-coupled systems agrees well with the Curry-Yorke model. The SPICE program has been modified to give realistic models for the diode resonator systems.

Nucleotide Inhibition of Glyoxalase II

Description: The glyoxalase system mediates the conversion of methylglyoxal, a toxic ketoaldehyde, to D-lactic acid. The system is composed of two enzymes, glyoxalase I (Glo-I) and glyoxalase II (Glo-II), and exhibits an absolute requirement for a catalytic quantity of glutathione (GSH). Glo-I catalyzes the isomerization of a hemithioacetal, formed non-enzymatically from methylglyoxal and GSH, to the corresponding a -D-hydroxyacid thioester, s-D-lactoylglutathione (SLG). Glo-II catalyzes the irreversible br… more

Nucleotide Sequence Determination, Subcloning, Expression and Characterization of the xy1LT Region of the Pseudomonas putida TOL Plasmid pDK1

Description: The complete nucleotide sequence of the region encoding the DHCDH function of the pDK1 lower operon was determined. DNA analysis has shown the presence of two open reading frames, one gene consisting of 777 nucleotides encoding a polypeptide of 27.85 kDa and another gene of 303 nucleotides encoding a polypeptide of 11.13 kDa. The results of enzymatic expression studies suggest that DHCDH activity is associated only with xy1L. However although the addition of xy1T cell-free extracts to xy1L cell… more
