Relationship between job attitudes and two forms of withdrawal from the work situation.

Correlated attitudes concerning the job in general and specific aspects of the work situation with termination decisions and recorded frequency of absences during the year following administration of job attitude questionnaire to 160 nonsupervisory female employees. Overall satisfaction and satisfaction with several intrinsic aspects of the work situation were significantly related to the termination criterion. None of the extrinsic variables were related. For the frequency of absence criterion, attitudes toward specific aspects of the work situation showed no consistent relationships when nonattitudinal variables were partialed out, but overall satisfaction was significantly related.

Sound propagation,density, and viscosity in liquid3He

We have measured the temperature dependence of the velocity and the attenuation of sound in the range 60–700 mK. The maximum in the sound velocity observed by Abraham and Osborne is confirmed. The viscosity deduced from the attenuation measurements is in good agreement with that of Abel, Anderson, and Wheatley but differs from that of Betts, Keen, and Wilks. The sound velocity as a function of pressure at 150 mK was also measured and from this the low-temperature pressure dependence of the density was determined.Based on work performed under the auspices of the U.S. Atomic Energy Commission.     

Gas chromatographic/mass spectrometric analyses of unknown analytical response in imported Fava beans: 4-chloro-6-methoxyindole

A halogenated unidentified analytical response (UAR) was encountered in a number of imported Fava bean samples during the Food and Drug Administration's routine pesticide-monitoring program. Gas chromatographic/mass spectrometric (GC/MS) analyses identified the halogenated component as 4-chloro-6-methoxyindole, a naturally occurring promutagen in Fava beans that has been linked to incidents of gastric cancer. Data from electron impact, positive and negative chemical ionization, collision-induced dissociation, and deuteration studies of this compound are presented, along with GC retention time data.     

Production of flat top beam profiles for high energy lasers

Production of uniform (flat top) high energy laser beam profiles with relatively little beam energy loss is possible through the use of a modified kaleidoscope, multiple reflection beam scrambler.

Psychiatric disorder and disability in New Zealand long-stay psychiatric patients

A study was undertaken of the prevalence of physical disease, psychiatric disorder and deviant behaviour in a sample of 137 long stay psychiatric patients at Porirua Hospital near Wellington, New Zealand. Patients were in the main male, single, middle-aged to elderly and of European descent. Schizophrenia was the most common diagnosis. Psychiatric symptoms were moderately severe, the most common being unusual mannerisms and posturing, anxiety, blunted affect, tension, unusual thought content and somatic concerns. Known physical disorders were present in 66 patients. Levels of neuroleptic medication were high and tardive dyskinesia was observed in almost 60% of patients. Frequency of deviant behaviour was low in absolute terms but nonetheless problematic. The frequency of deviant behaviour was similar to those reported for British patients.     

Ictal and interictal technetium-99m-bicisate brain SPECT in children with refractory epilepsy

Identification of epileptogenic foci in patients with refractory epilepsy remains a significant diagnostic challenge. Magnetic resonance imaging studies frequently fail to reveal an anatomic origin for the seizures, and scalp electroencephalography is often limited to identification of the involved hemisphere. Functional imaging modalities such as PET and SPECT are more promising tools for this application because they reflect the functional pathology associated with the seizure. These changes are more pronounced ictally, but until recently, no radiopharmaceutical was available that could be used routinely for ictal SPECT. The present study was therefore undertaken to determine whether 99mTc-bicisate could be used in ictal SPECT in pediatric patients with refractory epilepsy, to compare the patterns of ictal and interictal blood flow in these patients and to compare the localization information provided by ictal SPECT with that available from other techniques. METHODS: Technetium-99m-bicisate/SPECT was compared prospectively with scalp EEG for its ability to identify a possible seizure focus in pediatric patients with refractory epilepsy. Ictal and interictal SPECT studies were performed in 10 patients (3-19 yr old, mean age 10.9 +/- 4.3 yr; 7 female, 3 male) in whom MRI scans revealed no lesions that might be responsible for the seizures. RESULTS: Ictal SPECT was performed in all patients, and all ictal studies revealed focal perfusion abnormalities. By comparison, four of the interictal SPECT studies showed regional hypoperfusion that corresponded to the regions of hyperperfusion in the ictal studies, and three showed regional hyperperfusion corresponding to the hyperperfused regions in the ictal studies. Three interictal studies revealed no abnormal perfusion. Scalp EEG provided localization information in five patients. CONCLUSION: These initial results suggest that ictal SPECT with 99mTc-bicisate is a more promising tool for the identification of epileptogenic foci than interictal SPECT or scalp EEG in patients without focal abnormalities on MRI.
