A longitudinal study of managerial progress, begun by the present 1st author and colleagues (1978, 1980) in 1972 in a Japanese department store chain, monitored the professional and dyadic development of a cohort group of 80 newly recruited male college graduates (mean age 23.6 yrs) over their 1st 3 yrs with the company. Seven waves of data were collected from Ss, their immediate superiors, and company records. After 7 yrs with the company, Ss were promoted to their 1st management positions. The present study examined the preemployment selection test results and measured quality of vertical dyadic exchanges between S and his immediate superior over the 1st 3 yrs and the interaction of these 2 factors in predicting the speed of promotion, annual salary, and size of bonus after 7 yrs. Results show that the 1st 3 yrs were critically important to Ss; the combined effect of exchange and ability produced significant contributions to all 3 career outcomes assessed.

BACKGROUND AND PURPOSE: The objective of this study was to determine the risk factors of stroke incidence and mortality. METHODS: Our data are based on a prospective cohort study of men aged 40 to 49 years after 12 years of follow-up. RESULTS: In age-adjusted Cox proportional-hazards regression analysis of 14,403 healthy men, diastolic blood pressure was a stronger predictor for stroke incidence and mortality than systolic blood pressure. Smoking was a stronger predictor of mortality than of incidence. However, there was no dose-response relation among smokers by increased cigarette consumption. Total serum cholesterol was a significant (P < .05) risk factor for stroke mortality and of borderline significance (P = .08) for stroke incidence. Increased physical activity at leisure was associated with reduced stroke incidence but not mortality. The myocardial infarction risk score comprising systolic blood pressure, total serum cholesterol, and daily cigarette smoking was a strong predictor of mortality and incidence. Body mass index, triglycerides, blood glucose, and physical activity at work were not found to be risk factors for stroke. CONCLUSIONS: Reduction of blood pressure, cessation of smoking, lowered cholesterol, and increased physical activity at leisure are individual measures to reduce the risk of stroke.  相似文献

To determine the risk factors for suicide, 6,891 psychiatric outpatients were evaluated in a prospective study. Subsequent deaths for the sample were identified through the National Death Index. Forty-nine (1%) suicides were determined from death certificates obtained from state vital statistics offices. Specific psychological variables that could be modified by clinical intervention were measured using standardized scales. Univariate survival analyses revealed that the severity of depression, hopelessness, and suicide ideation were significant risk factors for eventual suicide. A multivariate survival analysis indicated that several modifiable variables were significant and unique risk factors for suicide, including suicide ideation, major depressive disorder, bipolar disorder, and unemployment status.

The recent elucidation of the inflammatory responses underlying asthma and allergic rhinitis has stimulated the development of new anti-asthma treatments, including numerous antileukotriene agents. These agents, which represent a new direction in targeted therapy, either antagonize the leukotriene receptor (e.g. zafirlukast) or block the synthesis of leukotrienes (e.g. zileuton). They have been used in preclinical and clinical studies involving normal subjects and patients with asthma or allergic rhinitis. These studies have generally supported the putative role of leukotrienes in the mechanisms of asthma and allergic rhinitis. With respect to asthma, the leukotrienes also appear to function as potent mediators of bronchoconstriction. The above cited results indicate that antileukotriene agents offer incremental improvements in airway caliber and may also attenuate the inflammatory response. Because they are orally administered, they should have the additional benefit of increasing patient compliance relative to other currently available treatments. In their current form, however, they may not be expected to replace the mainstays of current therapy but to act rather, as adjuvant therapy. Patients with relatively mild asthma may be able to achieve efficacy with an antileukotriene agent plus as needed beta-adrenergic agonists; patients with more significant disease might use antileukotriene agents as a supplement to another anti-inflammatory agent, such as cromolyn, nedocromil, or corticosteroids. Studies of asthma patients have confirmed the ability of antileukotriene agents to attenuate asthma-associated bronchoconstriction. Antileukotriene agents appear to significantly attenuate aspirin-, allergen-, and exercise-induced asthma, as well as the signs and symptoms of nocturnal and chronic asthma; they may have efficacy in other inflammation-associated disorders such as allergic rhinitis as well.  相似文献

Conducted a longitudinal study of 100 college students who had sought counseling and 100 who had not, 7 yrs subsequent to an earlier study and 4 yrs after graduation (or the time when graduation would have been expected). Results indicate that several differences between the 2 groups in the original study were largely attenuated with the passage of time. Ss who had sought counseling had significantly improved their former status on several measures. Implications are made concerning both student development research and the impact of counseling.

A double-blind, placebo-controlled study was carried out to test the clinical efficacy and safety of local nasal immunotherapy (LNIT) in powder form. Twenty-two patients suffering from allergic rhinitis strictly associated with early spring symptoms, with positive skin prick tests and RAST for birch-alder, all responders to a specific nasal provocation test (NPT), received randomly active or placebo treatment for 4 months. Immunotherapy consisted of administration of a set of capsules containing progressively increasing amounts of birch (Betula pendula) and speckled alder (Alnus incana) allergens in powder form with controlled granulometry. The active (birch-alder) and placebo (lactose) group completed the treatment according to a similar schedule. During the pollen season (March-April), the patients who took the active treatment reported less sneezing and rhinorrhea than the placebo group, on the basis of a symptoms score, and the differences were statistically significant; the need for drugs (terfenadine) was also significantly reduced. These findings agreed well with the results of specific NPT after the treatment; only patients in the active group had a higher threshold dose of nasal specific reactivity to birch-alder allergens than in tests before the LNIT.  相似文献

BACKGROUND: Laparoscopic splenectomy is a novel approach for the treatment of idiopathic thrombocytopenic purpura (ITP) in patients requiring surgical intervention. This technique was used for treatment in 16 consecutive patients. Follow-up was initiated at a median of 13.5 months after surgery to determine whether or not laparoscopic splenectomy is a safe and successful procedure that should be used in all patients requiring splenectomy for ITP. METHODS: Sixteen patients underwent laparoscopic splenectomy for ITP between May 1994 and September 1996. They were evaluated prospectively prior to surgery, immediately following surgery, at discharge, and at 13.5 months following surgery (n = 14) to determine the short- and long-term results of the procedure. RESULTS: Mean operation time was 123.4 +/- 12.1 min, and there were no significant intra- or postoperative complications. Mean intraoperative blood loss was 437.5 +/- 73.5 ml. Autologous blood transfusion was necessary in one patient (6.3%). Mean organ weight was 202.2 +/- 47.3 g. Mean postoperative hospital stay was 4.6 +/- 0. 4 days. Before discharge, mean platelet count rose by 100.7%. At follow-up (13.5 months postoperatively), it was 77.7% above preoperative values. No additional surgery was necessary in any of the patients undergoing laparoscopic splenectomy, and hematologic success was achieved in 12 patients (85.7%). CONCLUSIONS: Our results clearly indicate that laparoscopic splenectomy is a safe and successful procedure in patients suffering from ITP. It offers the well-known advantages of minimal invasive surgery as well as the surgical effectiveness of the open approach. This surgical technique should therefore be considered in all patients requiring splenectomy for the treatment of ITP.  相似文献

The intermediate filament nestin is highly expressed in multipotential stem cells of the developing central nervous system (CNS). During neuro- and gliogenesis, nestin is replaced by cell type-specific intermediate filaments, e.g. neurofilaments and glial fibrillary acidic protein (GFAP). In this study, we demonstrate that nestin expression is re-induced in reactive astrocytes in the lesioned adult brain. Following ischaemic and mechanical lesioning, a strong and sustained expression of nestin was noted in GFAP-positive cells surrounding the lesion site. Lesion experiments in transgenic mice carrying the lacZ gene under control of regulatory sequences from the nestin gene suggested that the upregulation of nestin in reactive astrocytes is mediated via the same sequences that control nestin expression during CNS development. These observations and recent data on the co-expression of glial and neuronal marker antigens in reactive astrocytes point to a close relationship between proliferating astrocytes and neuroepithelial precursor cells.  相似文献

We have reviewed 11 patients with congenital absence of the thumb, treated by pollicisation of the index finger, after follow-up for 20 to 38 years. Seven of the hands also had an associated radial club-hand deformity. Function as assessed by the Percival score was excellent in six, good in three, fair in two and poor in four; three of the poor results were in patients with radial club hand. Ten of the 15 transfers were used as normal thumbs, but in five hands function required trick movements. Of the seven unilateral cases, two transplants were used as the dominant hand, and in another two thumb strength was more than 50% of that on the opposite side. For patients with isolated congenital absence of the thumb, pollicisation of the index finger gives good functional and cosmetic results which are maintained. The results are less reliable for those with radial club hand.  相似文献

The dose-response calculation for radio assay of vitamin B12 is carried out using a straight line and a third degree curve to fit the experimentally obtained calibration points. It is shown that high dispersion of the calibration points with respect to the regression line can lead to errors in the calculation of the response. The calculation of the mean dispersion sx with respect to the regression line turns out to be a good criterion for checking the accuracy of the results.  相似文献

We reviewed 59 hips in 44 children with slipped capital femoral epiphysis (SCFE), all treated by in situ pinning. The average clinical and radiographic follow-up was 11.4 years. Fifty-three hips (90%) were rated as either excellent or good. Osteonecrosis or chondrolysis developed in five patients. Postoperative remodeling was noted, not only by a process of local resorption and apposition of bone, but also by correction of the disturbed anatomic axes, in proportion to the severity of the slip, together with global thickening of the femoral neck. We believe that the good long-term results after in situ pinning are the consequence of this important remodeling process.  相似文献

This three-wave 35-year prospective study used the Job Demands-Resources model and life course epidemiology to examine how life conditions in adolescence (1961–1963) through achieved educational level and working conditions in early adulthood (1985) may be indirectly related to job burnout 35 years later (1998). We used data (N = 511) from the Finnish Healthy Child study (1961–1963) to investigate the hypothesized relationships by employing structural equation modeling analyses. The results supported the hypothesized model in which both socioeconomic status and cognitive ability in adolescence (1961–1963) were positively associated with educational level (measured in 1985), which in turn was related to working conditions in early adulthood (1985). Furthermore, working conditions (1985) were associated with job burnout (1998) 13 years later. Moreover, adult education (1985) and skill variety (1985) mediated the associations between original socioeconomic status and cognitive ability, and burnout over a 35-year time period. The results suggest that socioeconomic, individual, and work-related resources may accumulate over the life course and may protect employees from job burnout.

Two multitrait-multimethod studies of academic and social intelligences show that cognitive and behavioral aspects of social intelligence (Experiment 1) and several cognitive aspects of social intelligence (i.e., social perception, social knowledge, and social insight; Experiment 2) can be discriminated. Verbal, nonverbal, self-, and other-report measures were administered to 134 female college students (Experiment 1) and to 227 male and female college students (Experiment 2). Convergent and discriminant validities were established for cognitive and behavioral dimensions of social intelligence (Experiment 1) and for two dimensions of cognitive social intelligence (social knowledge and social perception; Experiment 2). In both studies, the cognitive social intelligence factors had poor convergent validities, and research participants were college students attending a highly selective university.

In this study we examined the nature of college-student depression and its relation to personality variables and to experiences unique to college life. Thirty-five depressed and 39 nondepressed students completed a depression inventory, a series of personality scales, and a survey developed to investigate the impact of potentially distressing components of college life. Results revealed that college-student depression, though mild in intensity, represents a serious problem: Three quarters of depressed students had been depressed for more than 3 months, and half had contemplated suicide. Both personality characteristics and experiential variables were found to be significantly related to depression, together accounting for approximately half the variance. We examined individual personality traits and experiential variables that were found to differ between depressed and nondepressed subjects, and we discuss the implications of the findings for counseling and for future research.

College students from 2 Minnesota universities were surveyed about their gambling involvement. Gambling was reported to be a common experience, with 87% having participated at least once in the previous year. Most students reported gambling at fairly infrequent levels, and few identified financial, social, or personal consequences as a result of gambling. The odds of being identified as a probable pathological gambler was high for men, those indicating a positive parental history for gambling problems, regular (weekly plus) users of illicit drugs, and those with poor grades.

Using the predictors available from a study of academic success, how well can future occupational success be predicted? 19 students reported in the Barthol and Kirk study (see 31: 6666) were used as Ss here. The predictors included standardized tests such as the SVIB, MMPI, Concept Mastery Test plus academic rankings. The criterion of job success was psychologists rankings based on a study of work records of the Ss. Although those with the best preparation and MMPI profiles did the best on the ratings for vocational success. Ratings of 3 faculty judges of the academic success of the Ss predicted vocational success most accurately. From Psyc Abstracts 36:04:4LB40G.
