AbstractThe promise of digitalization is enormous and nowhere is it more critical than in its potential to transform food supply chain. Consumers have become more educated and are demanding real-time updated information on foods they consumed through digital media. They are also increasingly demanding to know if the foods they consume are environmentally and socially sustainable or not. As a result, food product traceability, safety, and sustainability issues have become crucial concerns to food retailers, distributors, processors, and farmers. Digitalization allows food supply chains to be highly connected, efficient, and responsive to customer needs and regulation requirements. However, digitalizing a traditional food supply chain is challenging and resource demanding. This is more so for developing countries where moving food from farms to consumers can take months as it travels through an array of middlemen. Unfortunately, little is available in the existing literature on food supply chain digitalization. So far, current researchers mainly explore the benefits of digitalization. Using cases in three companies, this paper explores the practices, challenges, and opportunities faced by Thailand food manufacturers in digitalizing their food supply chains. A framework for food supply chain digitalization is proposed and its implications for research and practices are discussed. 相似文献

A screening approach is developed for volatile organic compounds (VOCs) to estimate exposures that correspond to levels measured in fluids and/or tissues in human biomonitoring studies. The approach makes use of a generic physiologically-based pharmacokinetic (PBPK) model coupled with exposure pattern characterization, Monte Carlo analysis, and quantitative structure property relationships (QSPRs). QSPRs are used for VOCs with minimal data to develop chemical-specific parameters needed for the PBPK model. The PBPK model is capable of simulating VOC kinetics following multiple routes of exposure, such as oral exposure via water ingestion and inhalation exposure during shower events. Using published human biomonitoring data of trichloroethylene (TCE), the generic model is evaluated to determine how well it estimates TCE concentrations in blood based on the known drinking water concentrations. In addition, Monte Carlo analysis is conducted to characterize the impact of the following factors: (1) uncertainties in the QSPR-estimated chemical-specific parameters; (2) variability in physiological parameters; and (3) variability in exposure patterns. The results indicate that uncertainty in chemical-specific parameters makes only a minor contribution to the overall variability and uncertainty in the predicted TCE concentrations in blood. The model is used in a reverse dosimetry approach to derive estimates of TCE concentrations in drinking water based on given measurements of TCE in blood, for comparison to the U.S. EPA's Maximum Contaminant Level in drinking water. This example demonstrates how a reverse dosimetry approach can be used to facilitate interpretation of human biomonitoring data in a health risk context by deriving external exposures that are consistent with a biomonitoring data set, thereby permitting comparison with health-based exposure guidelines. 相似文献

Nowadays, it is popular that the dealer makes profits by selling a kind of discount coupons, which can be used as money to
purchase commodities with total cost less than or equal to the face value of the coupon. We can purchase a coupon at a price
of 0<s≤1 times its face value and the number of potential purchasable coupons is a given integer l. The customer has the option to buy the goods by cash completely or by a discount coupon. However, each piece of goods can
only use one coupon and the coupon used must have enough balance for the goods. The objective is to minimize the total cost
for purchasing all the goods. In this paper, we reduce the problem to a special bin packing model. We consider the online
problems for all 0<s≤1 and 1≤l≤∞. We present optimal online algorithms for all 0<s≤1 when l=∞ and l=1. For 2≤l<∞, we give both a lower bound and an algorithm, and show the algorithm is optimal for l=2.

明代冯梦龙编辑的民歌集<挂枝儿>保留了相当数量的新兴的口语成分原貌,是研究明代词语的宝库.这些材料虽经学者发明,但仍有新词新义值得作进一步梳理.例如"波""一向""的当""寡茶""闯寡门""统口""一丢"等等.这些词语不仅大型语言词典失收,其他论文论著也少提及.此文训释词语10条. 相似文献

《烽火田园》和《光荣》都是好莱坞以美国内战作为题材和背景摄制的影片,但前者反对战争、饱含人性色彩,后者支持战争、赞颂黑人历史功绩,主题思想大相径庭。这是什么原因?该文通过对两片制作时期的历史背景进行分析得出结论:它们都是在借用内战的某些事件反映制作时期的社会状况和文化氛围,表达的是制作时期的社会舆论趋向。 相似文献

抗战胜利后 ,国民党抢夺抗战胜利果实的“抢夺”应称为“独占”。台湾回归祖国的“回归”用法不当 ,台湾不存在“回归”问题 ,应改称“统一”等。国民党政权在大陆覆灭的标志不应是 1949年4月 2 3日南京解放 ,而应是 1949年 10月 1日中华人民共和国成立 相似文献
