- Examined whether inhibition should be considered a trait dimension, or whether those who manifest extreme inhibition constitute a discrete personality type. Also examined was whether there are sex differences in stability of inhibition. These questions were addressed using mothers' ratings over 16 yrs and psychologists' ratings over 6 yrs of a longitudinal sample. Ss were 212 children (122 boys and 90 girls). From the mean of mothers' 18- and 24-mo ratings and the mean of psychologists' 18- and 24-mo ratings, later ratings through 16 yrs were predicted. Analyses were performed for children constituting the extreme 10-15% from each end of the distribution and then for children not rated as extreme. Ratings were more stable for children in the extreme groups than for those in the nonextreme groups through 6 yrs; however, only for the inhibited girls did early inhibition predict inhibition into adolescence.

- The fluoroquinolone sensitivity of Pseudomonas aeruginosa and Klebsiella pneumoniae was studied by determinations of Minimum Inhibitory Concentrations (MICs) of norfloxacin and ciprofloxacin in consecutive clinical isolates. In P. aeruginosa, resistance or reduced susceptibility (MIC > or = 8 mg/l for norfloxacin and > or = 2 mg/l for ciprofloxacin) was found in 17% (9/54) of the isolates. Reduced susceptibility (MIC > or = 2 mg/l for norfloxacin) was found in 12% (10/84) of K. pneumoniae isolates. P. aeruginosa strains isolated in 1991 had reduced susceptibility to both norfloxacin and ciprofloxacin significantly more often than isolates from 1984-85 (p = 0.02). 10/84 K. pneumoniae strains from 1991 had reduced susceptibility to norfloxacin, compared with 1/34 from 1984-85. This difference was not statistically significant (p = 0.11).

Evaluation of polymerase chain reaction, tuberculostearic acid analysis, and direct microscopy for the detection of Mycobacterium tuberculosis in sputum
- 1992

Tidskriftsartikel (refereegranskat)abstract
- Tuberculosis remains a major global cause of morbidity and mortality. There is an urgent need for improved bacteriologic diagnosis of Mycobacterium tuberculosis infection. Three methods for rapid identification of M. tuberculosis in sputum samples (direct microscopy, gas chromatography-mass spectrometry [GC-MS], and polymerase chain reaction [PCR]), were compared with culture on Lowenstein-Jensen medium. Growth of M. tuberculosis was observed in 38 of 145 sputum samples. Detection of acid-fast bacilli by direct microscopy gave a sensitivity of 66% and a specificity of 100%. Detection of tuberculostearic acid by GC-MS gave a sensitivity of 55% and a specificity of 87%. Amplification by PCR of a fragment of the insertion sequence IS6110 gave a sensitivity of 95% and a specificity of 93% compared with culture and a corrected specificity of 99% compared with both culture and clinical data. This study indicates that PCR can be adapted for clinical use and is the method of choice for rapid diagnosis of pulmonary tuberculosis.

The relationship between maternal attributes in the early life of the child and the child's future criminal behavior

Tidskriftsartikel (refereegranskat)abstract
- The relationship of various personality and behavior describing characteristics of the mother in earliest childhood (ages 1–3) and in later childhood (ages 6–8) to the child's registered criminality up to the age of 30 was investigated for a sample of 122 males. Maternal attributes were rated by psychologists and nurses. Canonical correlations, measuring the relationship between the set of maternal attributes in young age of the child and the future registered criminality of the subjects, were in the magnitudes of .40 to .50. Both in early and in later childhood, mother's mood and her perceived maturity were attributes that, controlled for socioeconomic status of the home and mother's age, were significantly related to the child's future criminal behavior. In addition, mother's affective attitude in later childhood was significantly related to registered crime among the subjects. The change in prognostic power of maternal attributes from early to later childhood was discussed.

Improved step edges on LaAlO3 substrates by using amorphous carbon etch masks

- We report a technique for the fabrication of sharp and straight step edges on LaAlO3 (LAO) substrates by ion milling. An electron beam lithography defined amorphous carbon film was used as an etch mask. It had very low ion milling rate and was easily prepared and removed. Atomic force microscopy was used to determine the step profile. YBa2Cu3O7 step edge junctions fabricated at the LAO steps show promising results. An IcRn product of 1 mV was obtained at 30 K. A Fraunhofer-like magnetic field dependence of Ic was obtained up to ±2 0. One weak link or possibly identical weak links in series for these step edge junctions were observed from the current-voltage (I-V) curves as well as from the magnetic field dependence of the I-V curves.
