Introduction: A 2-year prospective study evaluated the effectiveness of a managerial training program to enhance corporate compliance with statewide worksite safety and health regulations. The program offered participants information about regulatory requirements and emphasized organizational and environmental strategies for reducing occupational injuries and illnesses. Objectives: To assess the effects of a train-the-trainer program on business managers' knowledge of statewide occupational safety and health legislation and on levels of corporate compliance with regulatory requirements. Methods: Forty-eight small- and medium-sized companies participated in the training sessions during the first year of the study. These firms were compared with 46 control companies that did not receive the training until the conclusion of the study. Results: Participation in the program was associated with higher levels of corporate regulatory compliance 12 months after the training sessions were held (controlling for baseline levels of corporate compliance with the regulations). Program effects on compliance levels were mediated by posttraining changes in managers' knowledge of regulatory requirements. Conclusions: The REACH OUT training program raised managers' awareness of and corporate compliance with statewide worksite safety and health regulations. Impact on Industry: Smaller companies face greater challenges than larger ones in developing and maintaining worksite safety and health programs. Barriers to regulatory compliance, especially in small- and medium-size companies, should be identified and removed to enhance the efficacy of these programs. 相似文献

Preeclampsia (PE), which affects about 2% of pregnancies, is a major cause of maternal and perinatal morbidity and mortality. PE can be subdivided into early onset PE with delivery <34 weeks' gestation and late onset PE with delivery ≥34 weeks. Early onset PE is associated with a higher incidence of adverse outcome. This review illustrates that effective screening for the development of early onset PE can be provided in the first-trimester of pregnancy. Screening by a combination of maternal risk factors, mean arterial pressure, uterine artery Doppler, maternal serum pregnancy-associated plasma protein-A and placental growth factor can identify about 95% of cases of early onset PE for a false-positive rate of 10%. © 2014 John Wiley & Sons, Ltd. 相似文献

We report the preparation of poly(3,4-ethylene dioxythiophene) (PEDOT)-modified polyvinylidene fluoride electrospun fibers and their use as a novel adsorbent material for the removal of the anionic dye Methyl Orange (MO) from aqueous media. This novel adsorbent material can be used to selectively remove MO on a wide pH range (3.0–10.0), with a maximum capacity of 143.8 mg/g at pH 3.0. When used in a recirculating filtration system, the maximum absorption capacity was reached in a shorter time (20 min) than that observed for batch mode experiments (360 min). Based on the analyses of the kinetics and adsorption isotherm data, one can conclude that the predominant mechanism of interaction between the membrane and the dissolved dye molecules is electrostatic. Besides, considering the estimated values for the Gibbs energy, and entropy and enthalpy changes, it was established that the adsorption process is spontaneous and occurs in an endothermic manner. The good mechanical and environmental stability of these membranes allowed their use in at least 20 consecutive adsorption/desorption cycles, without significant loss of their characteristics. We suggest that the physical-chemical characteristics of PEDOT make these hybrid mats a promising adsorbent material for use in water remediation protocols and effluent treatment systems. 相似文献
