We study the impact of product definition in electricity auctions. Recognizing the key role of the auction rules—pay as bid, uniform—the definition of the product itself emerges also as a critical step. Poorly designed products may impact both the market performance and the physical operation of the system. We investigate the impacts that the product definition can have on the market outcomes. A product definition implemented in some electricity markets is used to unveil critical aspects that must be considered when electricity products are defined. Our results provide guidelines for improving the product definition in electricity auctions. 相似文献

We conceptualized security-related stress (SRS) and proposed a theoretical model linking SRS, discrete emotions, coping response, and information security policy (ISP) compliance. We used an experience sampling design, wherein 138 professionals completed surveys. We observed that SRS had a positive association with frustration and fatigue, and these negative emotions were associated with neutralization of ISP violations. Additionally, frustration and fatigue make employees more likely to follow through on their rationalizations of ISP violations by decreased ISP compliance. Our findings provide evidence that neutralization is not a completely stable phenomenon but can vary within individuals from one time point to another. 相似文献

This article covers recent developments of material research in Thailand with a focus on environmental sustainability. Data on Thailand’s consumption and economic growth are briefly discussed to present a relevant snapshot of its economy. A selection of research work is classified into three topics, namely, (a) resource utilization, (b) material engineering and manufacturing, and (c) life cycle efficiency. Material technologies have been developed and implemented to reduce the consumption of materials, energy, and other valuable resources, thus reducing the burden we place on our ecological system. At the same time, product life cycle study allows us to understand the extent of the environmental impact we impart to our planet. 相似文献

ABSTRACTThe purpose of this study was to examine the influence of trust variables (trust: competence, trust: benevolence, trust: integrity) on leadership regarding the organization’s information security policy (ISP) compliance. An instrument with four constructs was used to collect data from 474 non-management subjects from various organizations in the USA. Collected data were analyzed through multiple regression procedure. Results revealed that all trust variables (trust: competence, trust: benevolence, trust: integrity) were influential in predicting the leadership regarding the organization’s ISP compliance. The findings are discussed and implications for practice are outlined. Conclusion, limitations, and recommendations for future research are drawn. 相似文献

Wave Energy Conversion (WEC) devices are at a pre-commercial stage of development with feasibility studies sensitive to uncertainties surrounding assumed input costs. This may affect decision making. This paper analyses the impact these uncertainties may have on investor, developer and policymaker decisions using an Irish case study. Calibrated to data present in the literature, a probabilistic methodology is shown to be an effective means to carry this out. Value at Risk (VaR) and Conditional Value at Risk (CVaR) metrics are used to quantify the certainty of achieving a given cost or return on investment. We analyse the certainty of financial return provided by the proposed Irish Feed-in Tariff (FiT) policy. The influence of cost reduction through bulk discount is also discussed, with cost reduction targets for developers identified. Uncertainty is found to have a greater impact on the profitability of smaller installations and those subject to lower rates of cost reduction. This paper emphasises that a premium is required to account for cost uncertainty when setting FiT rates. By quantifying uncertainty, a means to specify an efficient premium is presented. 相似文献

《Energy Policy》2015
Policy goals to transition national energy systems to meet decarbonisation and security goals must contend with multiple overlapping uncertainties. These uncertainties are pervasive through the complex nature of the system, the long term consequences of decisions, and in the models and analytical approaches used. These greatly increase the challenges of informing robust decision making. Energy system studies have tended not to address uncertainty in a systematic manner, relying on simple scenario or sensitivity analysis. This paper utilises an innovative UK energy system model, ESME, which characterises multiple uncertainties via probability distributions and propagates these uncertainties to explore trade-offs in cost effective energy transition scenarios. A linked global sensitivity analysis is used to explore the uncertainties that have most impact on the transition. The analysis highlights the strong impact of uncertainty on delivering the required emission reductions, and the need for an appropriate carbon price. Biomass availability, gas prices and nuclear capital costs emerge as critical uncertainties in delivering emission reductions. Further developing this approach for policy requires an iterative process to ensure a complete understanding and representation of different uncertainties in meeting mitigation policy objectives. 相似文献

Food waste is a significant problem and consumers’ tendency to reject misshapen produce has been identified as a key contributing factor. The current work investigates the implications of consumers incorporating aesthetic beauty into their prototypes—mental renderings—of fruits and vegetables. It is proposed that consumers have idealized prototypes for produce and this impacts the aversion to misshapen produce. The authors draw on prototype theory to predict that consumers’ personal experiences will influence the extent to which their prototypes for these foods have been biased towards aesthetic beauty and, consequently, how they respond to produce that is misshapen. Across three studies, the authors demonstrate that consumers who have direct experience with produce cultivation view produce that is low in aesthetic beauty as more prototypical, less disgusting, and more desirable. This work contributes to the food waste literature by offering novel insights into the psychological basis of the aversion to misshapen produce. These findings also present important implications for food policy. 相似文献

Housing and health issues can vary over time and between populations. The elderly population is increasing worldwide. Yet only limited information exists about housing conditions: changes over time, and the relationships between health and safety among the elderly. Based on repeated surveys (2007 and 2011), housing and health issues in Finland were assessed, especially among the elderly (more than 65 years old). From various housing factors studied, the largest differences between surveys were in thermal comfort. From the six outcomes studied – satisfaction with the dwelling, maintenance, indoor air quality (IAQ), perceived safety, general health, and sleeping difficulties – only satisfaction with the dwelling had significant temporal variation. Modelling the outcomes led to a selection of variables that were significantly associated with the outcomes. The models’ sensitivity was 65–81% for perceived safety and satisfaction with the dwelling, maintenance, and IAQ, whereas it was only 5% for sleeping difficulties and 32% for general health status. Among the elderly, higher odds ratios (ORs) were found for the associations between housing satisfaction and non-elevated radon concentrations, accessibility, dwelling size, and stuffy odour, as compared with the total population sample. The results are useful for developing policies that increase wellbeing, and for building owners wishing to increase housing satisfaction among occupants. 相似文献

结合全球倡导的营养导向型农业和功能性食品的内容,首次提出“功能性小麦品种”的概念,将其定义为“含有对人体健康有益的活性成分,可调节人体有益代谢,能给人体健康带来某种益处或满足特定人群的特殊需求,同时可以作为日常食物的口感正常、无毒副作用的小麦品种类型”;结合疫情警示和我国进入后工业时代后,人们需求必将由“吃得饱”、“吃得好”向“吃得健康”转变,因而提出继高产品种、优质品种之后培育“功能性小麦品种”的育种目标。根据多年关于小麦淀粉、蛋白、酯类和其他成分的功能研究结果,介绍新育成的“麦黄酮”、“高色素”、“高抗性淀粉”、“富锌”、“低醇溶蛋白”和“低植酸”等功能性小麦新品种(系)的营养特性和农艺产量状况;根据“健康中国2030”规划等国家战略,进行“功能性品种培育是解决我国功能性食品‘卡脖子’的关键基础,一种功能性品种可以形成一类功能性食品,多种功能性品种可以形成我国功能性面制品产业,推动我国整个食品工业的发展”的前景展望;根据功能性品种及其食品的稳定性和可靠性是产品和市场的“生命线”,从对消费者负责的高度,提出关于“功能性农作物品种审定导向和组建功能性成分检测机构;编制有关功能性品种和食品的国家或行业标准,设立功能性食品和功能性农作物品种的商业标志,保证我国功能性农作物品种及其食品健康发展”等方面的具体建议。 相似文献
