Attempted to learn how the Self-Directed Search (SDS) achieves its effects: Are the effects of the SDS on students due largely to its transparent structure and the large number of occupational options presented? Can these effects be enhanced if students are given an instructional booklet about the SDS and J. L. Holland's typology? These hypotheses were investigated in a Structure?×?Options?×?Instruction design with 104 high school girls randomly assigned to the 8 conditions. Ss were assessed before and 2 mo after treatment for their vocational aspirations, knowledge of the typology, and information seeking. The nonsignificant findings imply that the SDS achieves its effects partly because of its numerous occupational options and that the use of an instructional booklet may also increase the number of options. Some speculations about the influence of counselors and interest inventories are offered. (11 ref) (PsycINFO Database Record (c) 2010 APA, all rights reserved) 相似文献

A modification of Kaufman's urinary incontinence device was implanted unsuccessfully in 5 patients. This device achieved passive urinary continence in each of these patients; however, all patients continued to experience moderate to severe stress incontinence. The results of this study challenge the concept that static urethral compression can achieve total urinary continence in patients with postprostatectomy incontinence. 相似文献

Conjugation of carboxypeptidase G and arginase, two enzymes of therapeutic interest, to a soluble dextran significantly enhanced plasma persistence in normal and tumour-bearing mice. A prolonged decrease in arginine concentrations in plasma of tumour-bearing mice was demonstrated by using the dextran-linked arginase. Gel filtration of dextran-enzyme conjugate showed that enzyme activity co-chromatographed as a single peak with carbohydrate, and enzyme was shown to be covalently linked to the dextran. 相似文献

Systemic mastocytosis is uncommon. A patient is reported with many of the characteristic lesions of this disorder but with two features not before described--the occurrence of mixed pyramidal and neuromyopathic neurological signs and the demonstration of lymph nodes with abnormal architecture by lymphography. 相似文献

Although the rise in blood copper is associated with onset of the acute haemolytic crisis of chronic copper poisoning in sheep, the sudden fall in erythrocyte glutathione is apparently not due to a direct action of the copper. Moreover the reduced glutathione of the red cells is converted to some form that is not capable of regeneration by the pentose-phosphate mechanism. Only negligible inhibition of the pentose-phosphate enzymes occurs. As the haemolysis proceeds, there is a rapid recovery of erythrocyte glutathione levels, and a marked increase in pentose-phosphate enzyme activity, consistent with influx of young red cells. It seems that the release of copper into blood from liver at the haemolytic crisis is associated with an increase of the oxidative state of the blood, possibly by simultaneous release of other components from the liver. 相似文献

Last year the University of Iowa conducted an in-house study of how federal regulations, executive orders, and agency administrative policies affected the day-to-day operations of the university on all levels. This article is an analysis and reassessment of the federal impact issue based on the information uncovered in the University of Iowa survey. 相似文献

The gastric emptying rate of an isotopically labelled solid meal was compared in 29 insulin-dependent well-controlled diabetics and 18 normal controls. The diabetics were assessed for evidence of autonomic neuropathy. No significant difference in gastric emptying rate was found between controls and diabetics with or without autonomic neuropathy. Only three diabetics had greatly delayed gastric emptying, but in one of these the test had given a normal result on an earlier occasion. 相似文献

Pseudomonas cepacia or Enterobacter species or both were isolated from blood cultures of 79 patients in a community hospital between April 1971 and March 1972. No common exposures other than venipuncture correlated with positive blood cultures. Pseudomonas cepacia, Enterobacter, and other Gram-negative enteric bacteria were cultured from aqueous benzalkonium chloride used for skin antisepsis prior to ordinary and blood culture venipuncture. Contamination of blood cultures by organisms from the antiseptic most likely accounted for positive cultures in 35 to 38 patients (92%) with P cepacia. The remaining three patients had repeated blood cultures positive for P cepacia and circumstantial clinical evidence of bacteremia; they may have contracted disease through exposure to the contaminated antiseptic. Substitution of an iodine-alcohol antiseptic abruptly reduced the isolation of P cepacia and Enterobacter. 相似文献

The ventral pedal gland in the foot of the mature female whelk Buccinum undatum L. consists of a shallow pouch containing a layer of elongated cells which partially penetrate a basement membrane overlying layers of smooth muscle. This glandular epithelium contains acid mucopolysaccharide cells, ciliated and interstitial cells as well as the upper part of a new type of subepidermal gland cell. These gland cells consist of an elongated extracellular tubular duct formed by an invagination of the cell membrane and lined by numerous microvilli. Into this duct are discharged packets of a densely staining secretion. The secretion packets are produced in Golgi regions around the nuclei of the cells and are passed up through the cell to the base of the duct through or along an extensive assemblage of microtubules. The secretion packets show organized internal structure and may contain aromatic aldehydes and protein associated with the sclerotization of the egg capsules, which pass through the gland after leaving the genital tract. 相似文献
