The market behaviors of the supply and demand sides in the power market are the issues that market participants, operators and regulators are most concerned about. This article starts from the two dimensions of power generation market behavior and demand market behaviour, analyzes the impact of power transaction behavior on supply and demand trend changes, and then studies the function of big data technology in correlation analysis. The qualitative data is converted into quantitative data, and then gray rule analysis and correlation coefficient analysis are used to mine association rules. The results show that demand response is the key factor that affects the change of load trend.

In this study, the two key factors affecting the thermal performance of the insert rubber and stress distribution on the tire sidewall were analyzed extensively through various performance tests and simulations to promote the development of run-flat tires. Four compounds and two structures of insert rubber were designed to investigate the effects of heat accumulation and stress distribution on durability testing at zero pressure. It was concluded that the rigidity and tensile strength of the compound were negatively correlated with temperature. The deformation was a key factor that affects energy loss, which could not be judged solely by the loss factor. The stress distribution, however, should be considered in order to avoid early damage of the tire caused by stress concentration. On the whole, the careful balance of mechanical strength, energy loss, and structural rigidity was the key to the optimal development of run-flat tires. More importantly, the successful implementation of the simulations in the study provided important and useful guidance for run-flat tire development.

The Impact

Vaccination against the COVID-19 virus began in December 2020 in the UK and is now running at 5% population/week. High Levels of social restrictions were implemented for the third time in January 2021 to control the second wave and resulting increases in hospitalisations and deaths. Easing those restrictions must balance multiple challenging priorities, weighing the risk of more deaths and hospitalisations against damage done to mental health, incomes and standards of living, education outcomes and provision of non-Covid-19 healthcare. Weekly and monthly officially published values in 2020/21 were used to estimate the impact of seasonality and social restrictions on the spread of COVID-19 by age group, on the economy and healthcare services. These factors were combined with the estimated impact of vaccinations and immunity from past infections into a model that retrospectively reflected the actual numbers of reported deaths closely both in 2020 and early 2021. It was applied prospectively to the next 6 months to evaluate the impact of different speeds of easing social restrictions. The results show vaccinations are significantly reducing the number of hospitalisations and deaths. The central estimate is that relative to a rapid easing, the avoided loss of 57,000 life years from a strategy of relatively slow easing over the next 4 months comes at a cost in terms of GDP reduction of around £0.4 million/life-year loss avoided. This is over 10 times higher than the usual limit the NHS uses for spending against Quality Adjusted Life Years (QALYs) saved. Alternative assumptions for key factors affecting give significantly different trade-offs between costs and benefits of different speeds of easing. Disruption of non-Covid-19 Healthcare provision also increases in times of higher levels of social restrictions. In most cases, the results favour a somewhat faster easing of restrictions in England than current policy implies.

This chapter discusses the complexity and challenges of exploring the impact of gender on women's ability to realise their potential in Nepal. It demonstrates the limitations of using binary divisions to exploring ‘gender' as a key factor that impacts upon women's lives. By analysing interviews with ‘inspirational' women in Nepal conducted between 2009 and 2012 the chapter highlights the importance of exploring intersectional factors that also influenced women's life experiences. Based on interviews with 34 ‘inspirational' women in Nepal the chapter explores how the term ‘inspirational' is defines and discusses the range of work being done by so many women in Nepal that is truly inspiring. Through a discourse analysis of their stories of childhood and education we can see what key factors have played a role in enabling these women to realise their potential and to overcome intersectional barriers to work in a range of diverse positions, from the first female District Development Officer to the first women to gain her doctorate from overseas, to women who have set up NGOS working towards a more equitable and just society to others who have set up their own businesses or becoming leading academics. The conclusion draws together some key recommendations for future research and policy makers as well as those seeking to promote more equitable sustainable development that truly includes women in the process as autonomous, heterogeneous actors in the development process

Customer relationship management (CRM) is a strategy that integrates concepts of knowledge management, data mining, and data warehousing in order to support an organization’s decision-making process to retain long-term and profitable relationships with its customers. Key factors for successfully implementing CRM (e.g., data quality issues, organizational readiness, customer strategies, selection of appropriate KPIs, and the design of the data warehouse model) are discussed with the main thrust of the chapter focusing on CRM analyses and the impact of those analyses on CRM data warehousing design decisions. This chapter then presents a robust multidimensional starter model that supports CRM analyses. Additional research contributions include the introduction of two new measures, percent success ratio and CRM suitability ratio by which CRM models can be evaluated, the identification/ classification of CRM queries, and a preliminary heuristic for designing data warehouses to support CRM analyses.

Topcoat paint is mainly composed of resin and pigment and hence its quality highly depends on the type and proportion of these two ingredients. This study aims at testing the formula of the topcoat paint for finding one that can achieve better quality for anti-aging. Various formulas of paint are applied on boards that will be put into ultraviolet accelerated test machines to simulate weathering tests. The gloss and color, before and after the tests, are collected and numerical prediction method M5P is used to grow model trees for discovering the key factors affecting aging. Based on the structure and the linear regression models in the trees, a better topcoat paint should be composed of a high proportion of resin and generally a low proportion of pigment. Good types of resin and pigment are also identified for keeping color and gloss.

The Impact

As academic activities and research performances become important criteria in evaluating the quality of a university, research activities have received a special concern from universities. The key questions are what prompts faculty members to do research and how to motivate them. In order to answer these questions, it is necessary to examine the factors affecting the research motivation, then measure the impact of these factors on the faculty members' research motivation. In this study, the authors employed the expansive expectancy theory proposed by Chiang & Jang to investigate key factors that motivate faculty members to conduct research. The regression results on data collected from a survey on 475 faculty members at universities in Hanoi showed that faculty members are motivated by the intrinsic instrumentality factor (INTIN), financial value factor (FINVA) and expectancy factor (EXPECT – the factor that yields controversial results in previous studies). These findings suggest that the research motivation of lecturers has a positive correlation with academic degree, administrative position and has no relationship with age and gender.

This research is written for travel lodging online marketplaces (like Airbnb and HomeAway) and academics in e-commerce and travel industries. Lodging offered through online marketplaces is rapidly growing in popularity among travelers, yet the beliefs about these services and the motivations for using them are not well understood. This study explored key factors associated with lodging marketplace transactions, as well as traveler motivations. More specifically, the research focused on answering the following questions: What beliefs impact consumers' intention to reserve lodging through online lodging marketplaces such as Airbnb? and How does the motivation to travel for pleasure moderate the impact of online lodging marketplace beliefs on intention? It appears that motivation for travel is a key factor in the acceptance and use of online lodging marketplaces. Also, the four factors of novelty seeking—alleviation from boredom, change from routine, surprise, and thrill—extend the applicability of TPB to the sharing economy. Implications for tourism are discussed.
