Mobile diaries – Benchmark against metered measurements: An empirical investigation

Researchers seeking to study the relationships between consumers' communications, attitudes, and behaviors could benefit from monitoring consumers over time, across multiple locations and channels, and in a way that reflects consumers' subjective perceptions. Diaries on smartphones (mobile diaries) can be used as a research tool for such purposes. A mobile diary is a self-report instrument whereby people use their mobile handset to repeatedly report experiences of interest. Mobile diaries are increasingly used in psychology, geography, medicine, and commercial marketing. Yet they have rarely been used for quantitative marketing research, and were not benchmarked against best-practice metrics in marketing.In this study, we aim to set the ground for using mobile diaries in quantitative marketing research. We first lay out the theoretical infrastructure for the usage of mobile diaries, and describe possible respondent reporting concerns, including concerns related to non-reporting, reporting over time, and concerns stemming from individual-level heterogeneity.We demonstrate the potential of mobile diaries, as well as the importance of the various concerns, using a benchmark test case in the context of primetime TV viewing. Our benchmark uses a sample of respondents with both mobile diary viewing reports and Nielsen People Meter (NPM) records. Our analysis reveals that averaging across all conditions, 47.4%–64.7% of the NPM records are reported by the diary. The major sources for mismatch are random time periods without alarms, short viewings, and periodic reporting inactivity (pulsing). Concerns such as a decrease in reporting rates over time (e.g., fatigue), smartphone ownership, and demographic variation across individuals have relatively small effects on reporting likelihood. Analyzing the cases in which diary reports do not have a matching NPM record, we find many of them can be attributed to out-of-home viewing and viewing on non-metered devices. This finding demonstrates how mobile diaries can complement metered measurements. Overall, aggregate diary-based ratings have a 0.90 correlation with NPM ratings.We discuss implications for designing and using mobile diary studies in marketing.     

清徐县优势农业与旅游业协调发展研究

[目的]发展优势农业是改造传统农业,加快农业现代化的有效途径之一,旅游业作为国民经济新的增长点,两者协调发展更有利于增加农民收入,促进新农村建设,同时也是农村社会经济可持续发展的必然要求。[方法]文章通过文献查阅法了解清徐县优势农业葡萄及葡萄文化旅游业等方面的相关研究及研究成果,结合实证分析法通过协调发展度函数构建模型对清徐优势农业协调旅游业发展进行定量分析。[结果]清徐县优势农业和旅游业的综合评价指数从2004年的0.118 6上升到2016年的0.985 8,总体呈上升趋势,同时协调度13年间,2004~2008年介于0.221 5~0.490 5之间,处于失调发展阶段,2009年为过渡阶段,协调度为0.524 3,2010~2015年协调度介于0.626 7~0.685 8之间,处于初级协调发展水平,2016年协调度为0.701 7,发展到中级协调发展水平。优势农业与旅游业协调发展有利于区域经济水平的提高和农业收入的增加。[结论]推动优势农业与旅游业协调发展,清徐县需加大散户经营管理力度,切实有效地解决散户存在的实际问题,夯实优势农业的基础,为旅游业发展提供更大的发展空间。     

基于西门子PLC除尘器粉尘防爆危险源信号检测及预警系统的研究

研发适用于滤袋式除尘器粉尘爆炸危险源信号的实时检测及预警系统。该系统综合应用工业控制、PLC控制、智能测控终端无线传输、云平台数据管理等技术。采用传感器分别监测除尘器运行时的进出风口压差、除尘器运行状态、高压脉冲喷吹压力和箱体温度。当监测信号不在系统预设的合理范围时,PLC输出就地预警信号,监测信号也可通过无线传输模块上传到云平台。运用云平台的数据分析功能,实现除尘器运行状态系统化监测和综合管理。     

广东湖北碳排放权市场动态相依性分析与风险测度

选择具有代表性的湖北和广东碳排放权交易市场为研究对象,利用GARCH-POT-Copula模型对这两个市场的动态相依性与组合风险度量进行分析。研究结果表明:广东和湖北碳排放权市场之间的相依度较小,两个碳排放权市场价格波动不能给对方市场带来较大的影响,两市场近似于独立存在。提出了要从配额指标、基础设施建设、报送系统、市场交易主体等方面建立健全和完善全国统一的碳排放权交易市场的建议。     

Can welfare be measured with a preference-satisfaction index?

Welfare in economics is generally conceived of in terms of the satisfaction of preferences, but a general, comparable index measure of welfare is generally not taken to be possible. In recent years, in response to the usage of measures of subjective well-being as indices of welfare in economics, a number of economists have started to develop measures of welfare based on preference-satisfaction. In order to evaluate the success of such measures, I formulate criteria of policy-relevance and theoretical success in the context of preference-satisfaction measures of welfare. I present a detailed case study of the methodological choices put forward in a prominent generalized proposal for measuring welfare through preferences recently published in the American Economic Review. I contrast this with an alternative welfare measure which also uses preferences to weight aspects of welfare: the ICECAP-A measure. I assess the methodology of both approaches in detail and argue that the two goals of a preference measure of welfare can only be satisfied at the expense of making a measure prohibitively costly.     

中国城镇化包容性发展中的公共投资支持影响研究

本文通过构建城镇化包容性发展指标体系，测度出中国2003—2015年30个省级区域的城镇化包容性发展指数，经莫兰指数检验发现其具有显著的空间正相关性。进而采用空间计量模型，基于户籍制度改革背景，从生产性公共投资、社会性公共投资与环保性公共投资三个方面研究公共投资对城镇化包容性发展的影响。研究结果表明，生产性公共投资与社会性公共投资对城镇化包容性发展均存在显著的正向支持作用，且户籍制度改革变量与二者产生了正向的交互作用，说明随着对人口流动限制的放松，生产性公共投资与社会性公共投资对城镇化包容性发展的支持作用有所增强，但环保性公共投资未能表现出显著的支持作用。在未来城镇化进程中，应当优化调整中国公共投资的行业结构与区域结构，从而更好地提升城镇化包容性发展水平。     

The Role of Green Collaborative Strategies in Improving Environmental Sustainability in Supply Chains: Insights from a Case Study

This article aims to quantify to what extent collaborative strategies are more effective than internal or organization‐level actions to green supply chains. In this regard, the impact of decisions made at different stages of a supply chain in a product's carbon footprint is quantified. Organizational and product carbon footprints are calculated using the Compound Method Based on Financial Accounts (MC3). The results underline that concentrating reduction efforts in some stages of the supply chain is more effective than implementing individual actions by the participants. Collaboration among the participants is needed to decide what practices are implemented, at what stage they are needed and how they are to be implemented. This article adds to the literature on supply chains and sustainability. Previous research suggests that collaborative strategies have great potential for reducing the carbon footprint of products, while indicating the need for empirical research to support this statement.
