Laboratory and Field Consumer Evaluation Relationships for Menu Items Processed in Retortable Trays for Quantity Foodservice

Problems associated with provision of food in quantity foodservices prompted the development and use of prepared food items processed in retortable trays. Consumer acceptance of such foods was required so that the items could be screened for foodservice application. Consumer tests, using small portion samples and sensory testing under laboratory conditions, gave a relatively reliable prediction of acceptability of most of the items under extended-use consumer testing during a field trial. Final field acceptance of some items was influenced by external factors not accounted for in laboratory testing.

Enterprise architecture,IT effectiveness and the mediating role of IT alignment in US hospitals

Despite the possible benefits of implementing healthcare information technologies, successful implementation of effective healthcare information technology is constrained by cultural and regulatory concerns and technical obstacles encountered when establishing or upgrading an organisation's enterprise infrastructure. In this paper, we advance Ross' four‐stage model of enterprise architecture maturity as a valuable IT resource for helping healthcare organisations sustain a competitive advantage. We use partial least squares (PLS) structural equation modelling to analyse survey data from 164 US hospitals at different stages of EA maturity. Our results provide evidence that enterprise architecture maturity directly influences the effectiveness of hospitals' IT resources for achieving strategic goals. Further, enterprise architecture maturity indirectly influences the effectiveness of IT resources when IT alignment is incorporated as a mediating variable. We discuss the implications of our findings for research and practice and suggest opportunities for future research.     

Model-guided evaluation of consumer products

An evaluation of a consumer product is presented as an example of how ergonomics models can guide data collection and interpretation by non-ergonomists. The product, a new cooking pan, was compared with its earlier counterpart on performance and safety tests for specific features. Model-guided evaluations produced data which could be well-fitted by linear relationships, and measures derived from the data could be interpreted in physical terms by engineers. This is now the standard methodology for pan evaluation in the client company.

车辆出行轨迹调查分析中的丢点轨迹还原

针对利用车牌照生成车辆出行轨迹过程中由于车牌遗漏而产生的丢点轨迹问题, 提出一种丢点轨迹还原方法。首先建立一次可达网络模型来描述调查点之间直接可达关系, 并构建轨迹还原解集; 考虑时距相符程度、路径模式匹配程度、路径曲折度指标, 构造轨迹的效用函数, 利用逼近理想解排序的TOPSIS法进行轨迹还原解集决策, 得到最优的还原解。通过一个丢点轨迹示例进行了实验分析, 结果表明, 该方法可以得到满意的丢点还原解。

CRUDi framework proposal: financial industry application

The alignment of information systems with the business goals of an organisation, although a topic of great importance, is not always properly valued or taken into consideration. In general, managers have different opinions to chief information officers (CIOs) in relation to IS, especially with regard to their importance and value to the business and also in terms of investment needs. Here, we discuss and study new approaches to methods and tools for assessing the relative importance of each information system to business, focusing on the financial sector including banks and insurance companies. We suggest the introduction of new key indicators for better decision support and to identify investment priorities, and present results regarding the relative importance of each process to support the business strategy. The primary goal for the inherent research project is to analyse the main problems and difficulties encountered by IS and IT managers, featuring different players and how they relate. The main contributions of this work are the CRUDi framework as a tool to improve alignment between business and IS strategies and the CRUDi survey and its results qualifying the financial sector's opinion regarding the relative importance of processes and investments.     

ADCP数据综合处理方法及软件系统研制

由于仪器本身的限制和水文测验的实际需要,ADCP自带的数据处理软件WinRiver需要同时解译若干个R文件,并对解译数据进行垂线时间和空间插值,才能获得整点时刻特定起点距的垂线数据。为了弥补上述不足,通过对ADCP原始文件R文件进行解译,并根据ADCP数据处理的理论,研制了ADCP数据处理软件系统。该系统在长江口水文测验的实际应用效果表明,软件在数据的预处理和后处理方面均取得了良好的效果,可以进一步推广。
