This study describes the incorrect use of child restraints among car drivers with young children and examines factors that may influence their misuse. A cross-sectional survey was undertaken in supermarket car parks with car drivers travelling with children under the age of 8 years. The main measure was errors in child restraint use. Short interviews were conducted with 1113 drivers with a close inspection of the child restraints used in the vehicles. Only 4% of children were unrestrained but 64% of drivers made at least one error in restraint use. Most respondents thought using a restraint was easy, but 65% of these drivers made at least one error. Child restraints are used, but many are incorrectly fitted and/or have the child incorrectly placed in them. Correct use is a moderately complex task. Restraint systems need to be designed to minimize the opportunity for error and maximize safety.  相似文献

Blockchain-based smart contracts have triggered polarised discussions. They have been applauded as a significant technological achievement, but also criticised as a dumb idea. Their application is rapidly expanding in the financial sector, public sector, supply chain management, and the automobile, real estate, insurance, and health care industries. With the growing use of smart contracts and an increasing variety of smart contracts applications, the debate over the legal implications of this phenomenon has intensified and many legal issues related to smart contracts are being examined. Legal scholars have highlighted potential legal pitfalls, controversies and incompatibilities with existing legal frameworks. Blockchain technology and smart contracts have also been fuelling an interest of legislators, who have begun to recognise regulatory uncertainties and are making the first attempts to introduce legislative solutions to address them. This paper aims to highlight the fervour of the scholarly debate surrounding smart contracts and contrast it with a rather modest response from the legislators thus far. The paper reiterates that smart contracts represent the future. Even though they challenge practitioners, scholars, and legislators, current legislative initiatives indicate that under most legal systems there are no major obstacles for smart contracts and to accommodate smart contracts within the existing legal frameworks we should expect legal evolution rather than revolution.  相似文献

This study examined the impact of inspector and operation type on restaurant inspection scores and estimated the probability of each violation found by each inspector and operation type. General linear models and a logistic regression model were employed to analyze 1,067 regular routine inspection results. The results of this study showed that inspector and operation type significantly impacted inspection scores, explaining 28.07% of the variation in scores. A significant difference was found in the prediction of the probability of each violation found by inspector and operation type. The estimated probability of each violation being found by inspector during a specific inspection of operation ranged from 0% to 47.9%. The probability of each violation occurrence by inspector and operation type was considered as specific training needs for inspectors and restaurant managers. Possible implications are suggested for training programs for inspectors and restaurant managers to improve standardized results of inspection.  相似文献

笔者通过认真分析《食品安全法》与现行出入境检验检疫法律法规之间的区别与联系,提出了自己的一些见解和观点,希望出入境检验检疫部门能够将《食品安全法实施条例》中一些原则性较强的内容在法定范围内予以细化,并且在《食品安全法》和《食品安全法实施条例》中涉及出入境检验检疫的缝隙处做出必要的立法填充,使其能够与相应的部门规章和规范性文件有机衔接。  相似文献

In this paper, the number of goods subject to inspection at European Border Inspections Post are predicted using a hybrid two-step procedure. A hybridization methodology based on integrating the data obtained from autoregressive integrated moving averages (SARIMA) model in the artificial neural network model (ANN) to predict the number of inspections is proposed. Several hybrid approaches are compared and the results indicate that the hybrid models outperform either of the models used separately. This methodology may become a powerful decision-making tool at other inspection facilities of international seaports or airports.  相似文献

In recent times, the increasing accessibility of mobile technology has led to changes in consumers’ purchasing behavior. Despite the gloom and doom hearsay about how electronic commerce is threatening the existence of brick-and-mortar stores, by some indications, however, webrooming (i.e., the practice of researching items online, and then buying them offline) may be an even more common practice among shoppers. Against this background, this study proposes and empirically validates a comprehensive research model which incorporates consumer traits (i.e., need for touch, need for interaction, and price-comparison orientation), channel-related factors (i.e., online search convenience, perceived usefulness of online reviews, perceived helpfulness of in-store salespeople, and perceived risk of buying online), and smart shopping perception as antecedents of webrooming intention. Moreover, this study examines the moderating role of product category in predicting webrooming intention. A questionnaire-based survey was conducted. A total of 280 useable responses was collected and data was analyzed using partial least square structural equation modeling. The findings revealed significant direct and/or indirect effects (through smart shopping perception) of consumer traits and channel-related factors on webrooming intention. In addition, product category was found to moderate the relationship between price-comparison orientation, online search convenience, perceived risk, and webrooming intention. Theoretical and practical implications are discussed.  相似文献

This paper explores the effects of utilitarian and hedonic benefits perceptions of discount sales promotions on consumer purchase decisions (attitude and behavioral intention). A closed-ended survey, as well as a partial least squares structural equation modeling of consumers sampling who had used discount sales promotions in their recent purchases, was utilized in this study. The findings suggest that utilitarian benefits perceptions derived from price-quality perception and hedonic benefits perceptions derived from smart shopper self-perception of using discount sales promotions positively affect consumer purchase decisions. Both utilitarian and hedonic benefits perceptions of discount sales promotions can henceforth be used to produce the desired effects on purchase decisions. Hence, this paper sheds light on the effects of utilitarian and hedonic benefits perception of discount sales promotions on purchase decisions. Though the findings are limited to discount sales promotions alone and two types of purchase decisions outcomes (attitude and behavioral intentions), this paper identified multiple avenues to extend its findings. This encourages further exploration of such promotion topics, particularly on the various perceptions of discount sales promotions as well as other sales promotion techniques among marketing academics and practitioners.  相似文献
