If only consumers knew: How sampling impacts wine innovation diffusion in the U.S. foodservice industry

A survey (n = 151) explored consumers’ experiences with wine-on-tap, a current trend in the U.S. foodservice industry. Wine consumers’ innovativeness (R² = .49) was explained by wine involvement, opinion leadership, and usage of information sources. Those who recently tried wine-on-tap (n = 43) were significantly more innovative (innovators) than those who never tried it (noninnovators). Furthermore, noninnovators expected to pay significantly less for a glass of wine-on-tap when compared with wine poured from a bottle. Contrary to expectations, the driving force for noninnovative behavior is lack of availability and awareness as opposed to a lack of interest in wine-on-tap.     

The coevolutionary process of restaurant CSR in the time of mega disruption

This study investigates how US foodservice conglomerates have embarked on corporate social responsibility (CSR) measures to circumvent dire situations during the COVID-19 pandemic. It explores the evolution of CSR practices from restaurant enterprises to rescue and salvage their stakeholders. By analyzing press releases from ten restaurant chains in three different crisis phases (incubation, acceleration, and climax) through corpus linguistics, we identify a CSR progression mechanism that coevolves with the aftermath of the crisis among their stakeholders. This study improvises the CSR- as-process view to highlight the time-variant dynamic nature of CSR development over the course of major disruption.     

How does the effect of pre-play suggestions vary with group size? Experimental evidence from a threshold public-good game

Numerous studies have examined factors influencing the likelihood of cooperative outcomes in nonzero-sum games, but there has been little study of the interaction between two of the most important: group size and pre-play cheap talk. We report results from an experiment in which groups of size between 2 and 15 play a one-shot multi-player threshold public-good game. In our random leader treatment, all group members select a suggestion (e.g., “Everyone should choose X”), with one randomly chosen to be broadcast to the group. In a choice only treatment, subjects choose suggestions but none is sent, and in a baseline treatment, there are no suggestions at all. We find a negative interaction between group size and this kind of communication: the beneficial effect of both suggestions overall and cooperative suggestions on cooperation, cooperative outcomes, and payoffs decreases sharply as the group size increases. We find a similar negative interaction in a follow-up treatment in which all group members’ suggestions are broadcast to the group. Our results suggest that care should be taken in generalising conclusions from small-group experiments to large groups.     

一种改进的CPFSK信号频率估计方法

针对突发信号解调中多普勒频偏大的问题，提出了一种改进的连续相位移频键控信号(CPFSK)频率估计方法。首先接收信号平方运算使信号的调制指数加倍，再通过一次离散傅里叶变换(DFT)，用搜索信号平方谱谱峰的方法实现突发信号频率估计。仿真实验表明，在低信噪比条件下，该算法的频率估计精度比经典的相位差频率估计算法提高了20%；该算法与广泛用于高动态突发信号的频率插值估计算法相比，同道干扰信道下信干比改善可达4 dB，DFT长度缩短约1/3。     

The effects of the visual presentation of an Influencer's Extroversion on perceived credibility and purchase intentions—moderated by personality matching with the audience

Influencers are ordinary individuals who have amassed large followings by demonstrating expertise in various niches on social media sites. We aim to propose (1) the visual presentation of an Influencer's extroversion as an antecedent to source credibility and purchase intentions and (2) personality matching in terms of extroversion between an Influencer and their audience as a moderator of such relationships. We chose the source credibility model and the similarity-attraction model as our theoretical frameworks. In our controlled online experiment (n = 165), the profile of a brand ambassador of a fashion brand was curated to create two levels of extroversion (i.e. low vs. high extroversion). Participants' self-reported extroversion levels were counterbalanced in these two conditions to create a personality match with the Influencer, entitled “extroversion congruence.” Our results suggest that the visual presentation of an Influencer's extroversion increases the perceived credibility of the Influencer and subsequent purchase intentions. Additionally, our findings show that these relationships were asymmetrically moderated by extroversion congruence: the positive effects of extroversion increase in the case of high extroversion among both the Influencer and their audience but decrease in the case of low extroversion.     

The repercussions and challenges of COVID-19 in the hotel industry: Potential strategies from a case study of Indonesia

The COVID-19 pandemic has hit the tourism and hospitality sector hard. Hotel managers face uncertainty in this environment in order to survive. This study explores the impact of COVID-19 on the hospitality industry, particularly hotels in Indonesia, one of the largest developing countries. It examines the challenges faced by hotel managers and the strategies used to survive. Through the lens of complexity theory, we discuss whether the strategies being deployed are beneficial, redundant, or detrimental for hospitality businesses. Based on semi-structured interviews with 13 hotel managers in Jakarta, Bandung, and Bali, the findings shed light on the various challenges to hotels. We also highlight which challenges could turn into opportunities. The findings show that the strategies that managers are deploying could be detrimental in the future. Potential future research directions are also discussed.     

变革中多渠道信息传递对员工绩效的影响机制

面对日趋复杂的外部环境,组织变革成为企业获得竞争力的重要方式。员工参与是组织变革成败的关键,充足的组织变革信息有利于员工积极投入变革。本文以社会信息加工理论为基础,对来自被兼并企业的36个工作团队185名员工进行研究,探索多渠道变革信息传递对员工的影响机制。基于多层次线性模型的数据分析结果表明:(1)变革情境下,组织正式渠道进行信息沟通和变革氛围包含的非正式信息,均能正向促进员工变革绩效;(2)员工所持有的积极变革期望,在多渠道信息传递和变革绩效间起到中介作用;(3)变革氛围跨层调节变革信息沟通对员工积极变革期望的正向作用,相比于低变革氛围情景,具有高变革氛围的团队,通过变革信息沟通更能显著提升员工对变革的积极期望。研究结论对企业变革实践中信息传递和沟通工作具有现实指导意义。     

Subprime cohorts and loan performance

Loan performance of subprime originations during the boom years of 2004–2006 is contrasted with that of subprime originations during the early period of 2000–2002. A counterfactual technique is developed to determine how originations during the early period would perform in a different environment, namely, the environment faced by originations of 2004, 2005, and 2006. In an environment where house prices are increasing rapidly, low credit score originations do not show high rates of default—as was witnessed for 2000–2002 cohorts. However, in an environment of stagnant or deteriorating home prices, low credit score originations show significantly higher rates of default than high credit score originations. With a greater proportion of low credit score originations, earlier cohorts of 2000–2002 were no less vulnerable to the environment faced by cohorts of 2004–2006. In essence, these results raise concerns about the viability of all cohorts of subprime originations because of their reliance on the appreciation of the underlying collateral rather than the creditworthiness of the borrower.
