What constitutes a constitutional amendment culture?

Why are some constitutions amended frequently and others hardly at all? An obvious candidate determinant is constitutional rigidity, i.e., the size and number of procedural barriers to amendment. Given some demand for amendment, greater rigidity implies a smaller supply. However, measures of rigidity often do not correlate significantly (or even with the predicted sign) with amendment rates. Ginsburg and Melton (2015) argue that amendment culture – “shared attitudes about the desirability of amendment” – is a more important determinant of amendment rates. We study up to 128 constitutional episodes from 54 countries and estimate relationships between amendment rates and Hofstede cultural indices. Cultures that are more individualistic and less prone to uncertainty avoidance are associated with higher amendment rates. When cultural dimensions are controlled for, the lagged amendment rate (Ginsburg and Melton’s proxy for culture) is not a robust correlate.

政府投资工程总承包项目设计优化认定与收益归属研究

工程总承包模式以设计与施工的高度融合,日益在建筑业受到青睐。但由于政府投资项目中存在有关结余资金上缴国库等规定,容易导致政府投资工程总承包项目下设计优化产生的成果是进行分成或作为结余资金上缴界定不清。鉴于此,本文通过政策文件,并结合政府投资项目特点,分析政府投资工程总承包项目设计优化的情形认定以及在不同结算依据和合同计价方式下设计优化收益归属的界定,为有效激励总承包单位积极进行设计优化奠定基础。     

乡村森林旅游项目规划中哲学元素运用的个案分析——以宜春市月都花溪谷项目为例

以江西省宜春市"月都花溪谷"乡村森林旅游项目规划中哲学元素的应用为个案,结合哲学理论进行分析。结果表明:乡村森林旅游项目规划应有哲学的自觉,根据项目所在地自然和人文资源禀赋,因地制宜地吸收哲学元素,从而打破乡村森林旅游项目同质化和见物不见人的困局,赋予乡村森林旅游项目以特色和灵魂。因此,提出突破森林旅游项目规划中一元化的经济思维定势、以哲学思维唤起人学意义、因地制宜激发内生式哲学文化活性等启发性建议。     

Digital hostages: Leveraging ransomware attacks in cyberspace

Global institutions face costly infrastructure disruption from cyberthreats such as ransomware attacks. The global threat of ransomware attacks has continued to increase over time. Although it is important to conduct a cost-benefit evaluation and to weigh the risks prior to engaging, a new emerging option of dealing with ransomware attacks should be considered. I outline an interdisciplinary approach to cybernegotiation combining features of online dispute resolution and terrorist hostage theory. In this novel cyber-based dispute system design, the Wade and seek method is the application of traditional hostage negotiation theory used to help businesses mitigate the costs of ransomware attacks.

Fairness perception of ancillary fees: Industry differences and communication strategies

This study examines fairness perception of ancillary fees across different industries, and ways to communicate ancillary fees in a way that reduces customers' feeling that they are being unfairly treated. Through surveys and consumer experiments, we show that consumers’ perception of fairness decreases as the level of ancillary fees increases, with differences across industries. Also, when the customer is given a cue that the ancillary fees are necessary for low base prices, fairness perception increases, explained by the “dual entitlement” concept. Another effective communication strategy is early disclosure, as opposed to late disclosure which decreases fairness perception and willingness to recommend.     

An empirical examination of the effects of design elements of email newsletters on consumers’ email responses and their purchase

In this research, we empirically explore the effects of various design elements of email newsletters on consumers' email responses and their purchases. We capture the consumers' email responses using three metrics, namely email open, email click, and email reopen. We operationalize consumers' purchases as their spending on product items that are featured in email newsletters. Using a novel email marketing database, first, we model the influence of design elements of email newsletter on consumers' email responses at the individual consumer level. The email design elements constitute several email attributes, situational factors, and integrated marketing communication. Second, we quantify the effects of these three email responses, open, click, and reopen, on consumers' purchases. Our empirical results suggest a significant influence of email attributes, situational factors, and marketing communications on consumers' email responses. Furthermore, among open, click, and reopen, we find clicks tend to have the highest impact on consumers’ purchase, followed by email reopening and opening. However, email newsletters with higher opening probability are more effective in influencing purchases than those email newsletters with higher reopening probability. Furthermore, consumers who indulge in all three email responses, namely opening, clicking, and reopening, tend to purchase the most. Results from our study offer several critical insights for email marketing strategy helping managers improving the effectiveness of email campaigns by careful consideration for the design elements of email newsletters.     

基于模糊多属性群决策的维护方式选择研究

维护方式选择是维护管理中的重要工作之一,合理的维护方式既能达到保障设备的稳定运行,又能同时兼顾其它各个方面的要求。由于对维护方式的评价涉及多个部门、人员和属性,有些指标只是一个模糊的概念,因而采用模糊多属性群决策的方法对维护方式进行优先抉择。本文结合A公司的设备维护方式选择问题,尝试使用模糊多属性群决策折衷算法求解最佳的维护方式。     

Technological character,function type,and the longevity of standardized knowledge

This study seeks to determine the validity of the current de jure standards management system. The de jure standard is an important tool for innovation policy. However, its review interval has been fixed in the management system and maintained without the use of empirical analysis to guide its development. Therefore, this study (1) examines the factors that affect the longevity of the standards, and (2) outlines methods for improving how the de jure standards are managed. Results indicate that design and mark standards influence the longevity of standardized knowledge. This is notable, given that design for innovation is an emerging area of research that is commonly studied through the analysis of design patent data. Taken together, this study’s major findings are twofold. First, different technological categories have significantly different effects on longevity. Because the longevity of some technological sectors is naturally longer than others, there exists a need for a more flexible interval system. Second, the longevity of the mark and design standard is longer than the longevity of other types of standards. Both developing and developed countries utilize the de jure standard, so the policy implications of these findings are widely applicable.
