Cognitive impairment is increasingly recognized as an important aspect of schizophrenia. Since cognitive impairment has many features in common with the negative symptoms of the illness, it is possible that some of the characteristics attributed to negative symptoms are due to an association with cognitive impairments. In order to test this hypothesis, 174(More)
OBJECTIVE This study used a cross-sectional design to examine the frequency of occurrence and severity of 10 different signs of thought disorder in schizophrenic patients across the lifespan. METHOD Schizophrenic patients, who ranged in age from 19 to 96 years (N = 392), were examined with the Scale for Assessment of Thought, Language, and Communication.(More)
This study investigated the use of the immediacy theory to explain the existence of auditory hallucinations and delusions in individuals with schizophrenia and to develop treatment strategies. In a 2-phase approach, a therapist trained 6 individuals with schizophrenia to stop responding to the immediate stimuli ostensibly evoking their symptoms and instead(More)
This study examined age-related differences and correlates of deficits on phonological and category fluency tasks performed by schizophrenic patients. Equal numbers (n = 41) of geriatric (age > 64) and nongeriatric chronically hospitalized schizophrenic patients were examined with tests of phonological and category fluency, verbal learning and delayed(More)
Plant-microbe interactions involve numerous regulatory systems essential for plant defense against pathogens. An ethylene-inducing xylanase (Eix) of Trichoderma viride is a potent elicitor of plant defense responses in specific cultivars of tobacco (Nicotiana tabacum) and tomato (Solanum lycopersicum). We demonstrate that tomato cyclopropyl isomerase(More)
Post-translational modification of target proteins by the small ubiquitin-like modifier protein (SUMO) regulates many cellular processes. SUMOylation has been shown to regulate cellular localization and function of a variety of proteins, in some cases affecting nuclear import or export. We have previously characterized two EHDs (EH domain containing(More)
Endocytosis is a crucial process in all eukaryotic organisms including plants. We have previously shown that two Arabidopsis proteins, AtEHD1 and AtEHD2, are involved in endocytosis in plant systems. Knock-down of EHD1 was shown to have a delayed recycling phenotype in mammalians. There are many works in mammalian systems detailing the importance of the(More)
Three elements are essential to an effective incentive strategy: various reinforcers, the employee's motivational needs and the organization's business goals. When these factors are integrated into a coherent incentive policy, employees can focus their attention on the company's business goals.
