红砂岩地区基坑开挖对周边建筑物的影响

本文通过对衢州地区的一个深基坑工程周边的学校食堂、宿舍的建筑物沉降的监测和分析,探讨了红砂岩基坑开挖对周边建筑物产生的影响。监测结果表明,基坑开挖会引起周边建筑物不同程度的沉降变形,且主要发生在基坑开挖前的打桩阶段和基坑开挖阶段。两栋建筑物的沉降累计值基本已超过20mm,且最大的沉降量已接近40mm,较大程度超过房屋沉降监测警戒值,说明开挖的施工方案有待于进一步优化,此结论对于红砂岩地区基坑工程施工具有重要的工程意义。     

Understanding repeat playing behavior in casual games using a Bayesian data augmentation approach

With an estimated market size of nearly $18 billion in 2016, casual games (games played over social networks or mobile devices) have become increasingly popular. Because most casual games are free to install, understanding repeat playing behavior is important for game developers as it directly drives advertising revenue. Game developers are keenly interested in benchmarking their game versus the market average, and understanding how genre and various game mechanics drive repeat playing behavior. Such cross-sectional analysis, however, is difficult to conduct because individual-level data on competitors’ games are not publicly available, and that the casual gaming industry is highly fragmented with each firm making only a handful of games.I develop a Bayesian approach, based on a parsimonious Hidden Markov Model at the individual level in conjunction with data augmentation, to study repeat playing behavior using only publicly available data. After applying the proposed approach to a sample of 379 casual games, I find that the average daily attrition rate across game is around 36.5%, with an average “play” rate of 47.9%, resulting in an average ARPU (average revenue per user) across games of around 20.5 cents. Certain genres are linked to higher attrition rates and play rates. In addition, giving out a “daily bonus” or limiting the amount of time that gamers can play each day are associated with a 17.7% and 16.4% higher ARPU, respectively.     

Corporate Lobbying and Firm Performance

Corporate lobbying activities are designed to influence legislators, regulators and courts, presumably to encourage favorable policies and/or outcomes. In dollar terms, corporate lobbying expenditures are typically one or even two orders of magnitude larger than spending by Political Action Committees (PAC), and, unlike PAC donations, lobbying amounts are direct corporate expenditures. We use data made available by the Lobbying Disclosure Act of 1995 to examine this more pervasive form of corporate political activity. We find that, on average, lobbying is positively related to accounting and market measures of financial performance. These results are robust across a number of empirical specifications. We also report market performance evidence using a portfolio approach. We find that portfolios of firms with the highest lobbying intensities significantly outperform their benchmarks in the three years following portfolio formation.     

Incentives to move up: Effects of pay gaps between levels on employee performance

Employees of a certain rank are motivated by the pay gap between them and the levels above (upward comparison), and the pay gap between them and the levels below (downward comparison). In some cases, employees face multiple upward comparisons such as immediate and subsequent upward comparisons. We hypothesise that upward comparison matters more than downward comparison, and in the case of multiple upward comparisons, the immediate one matters more than the subsequent ones. We also hypothesise that the pay gap effect resulting from the upward/downward comparison ought to be non‐linear in that performance increases with pay gap size at a decreasing rate. The results from two empirical studies, namely, a longitudinal field study and a laboratory experiment, largely support our hypotheses.     

传统白族民居如何适应现代功能需求——以沙溪白族民居为个案

沙溪的传统白族民居保存较好,数量庞大,既有大理白族民居的特点又有沙溪的地方特征。民居建筑材料为土、木、石。沙溪地区太阳辐射剧烈,冬季严寒,为提升室内舒适度,需要一些现代建筑技术手段来解决这些问题。随着社会的发展,为了适应现代化的生产方式,民居的功能空间发生了改变,并且伴着旅游开发,商业也作为一个不可缺少的因素融入到了沙溪民居中。
