Nature-based experiences can contribute to individuals’ connection to nature and intentions toward sustainable environmental behaviours. Conservation psychology can use tourism as a platform to modify tourists’ intentions and behaviours regarding key marine threats such as single-use plastics. This study examined changes to pro-environmental intentions, particularly regarding plastic use, in 267 nature-based tourists from Australia and Tonga who completed a whale watching/swim experience. A theory of planned behaviour (TPB) framework was used incorporating moral norms and environmental identity, which have been previously implicated in explaining pro-environmental actions. This study found that including moral norms in the TPB model significantly increased the ability to predict pro-environmental intentions. Further, when controlling for the TPB and moral norm variables, environmental identity explained a further 15% of tourists’ pro-environmental intentions. The findings suggest the original TPB model may be less suitable within a marine conservation context. Collectively, positive nature-based experiences, environmental identity, and moral norms are important in understanding tourist’s intentions to engage in sustainable environmental behaviours. 相似文献

This paper examines the cumulative market reaction to the events related to deferral of internal control audit requirement under the Sarbanes-Oxley Act of 2002 and its elimination under the Dodd-Frank Act of 2010 for nonaccelerated filers (small firms). We document that small firms experienced negative cumulative abnormal returns around these events; and the differences between the cumulative abnormal returns for small firms and the two control groups (accelerated and large accelerated filers) were negative and significant at the 1% level. These results support the notion that market participants value the reliability of financial information irrespective of the firm size. Within the small firms, we find no firm characteristic significantly explains the market reaction to the events considered. That is, all small firms lost market value in reaction to the events that delayed and eliminated their internal control audit requirement. 相似文献

The article titled “Defining Supply Chain Management” published in 2001 in the Journal of Business Logistics has been cited over 4,900 times in the last 17 years. In this paper, we first provide a historical review of how the article originated and the contributions the article made to both the theory and practice of supply chain management (SCM). Next, we highlight the key market and technological changes that have emerged in SCM followed by how the theory proposed in the 2001 article can still be relevant to support SCM research and practice going forward. We also propose ways of configuring a supply chain and partnering across companies to serve customers in an optimal way. We conclude with a call for research on developing new frameworks to better describe, explain, predict, and shed light on the evolving nature of SCM. 相似文献

Sensory elements are an important aspect of both offline and online retail stores and can non-consciously influence consumer judgments and purchase behavior. In offline settings, ambient factors like scent, lighting, and music have been shown to influence customers’ shopping experiences and their buying behaviors. For online retail outlets, sensory factors related to color, display patterns, and layouts can have significant effects on consumer behavior. Sensory elements have strong managerial relevance since they can non-consciously influence behaviors and because they are relatively easy to change; for example, it requires minimal effort to change the lighting or the music at a physical retail store or the display pattern for an online store. The eight papers in this special issue address theoretical and practical issues related to how different sensory elements can strongly influence retail practices. These papers focus on underexplored topic areas and also on emerging technologies, which stimulate thoughts for further research in these areas. 相似文献

This article makes use of hourly crime counts to model the relationship between events that take place at the Prudential Center in Newark, NJ and robberies, an arena that has caused local controversy regarding the costs and benefits of hosting such an entertainment venue. Results from the econometric model suggest that the NHL’s New Jersey Devils ice hockey games, concerts, and Disney-themed events are all associated with increases in robbery, while various other event categories such as the NBA basketball games played by the Nets and boxing, and mixed martial arts (MMA) matches are not associated with an increase. These findings support two complementary ecological theories of crime that focus on how events provide additional opportunities for crime by increasing the associated benefits while simultaneously decreasing the cost for economically motivated offenders to take advantage of. 相似文献

We collected 469 frontal face images of Ukrainian cabinet ministers who were in office in 2000–2020. For each image, the minister's body mass index was estimated using a computer vision algorithm. The time series of median estimated body mass index of cabinet ministers co-moves over time with two existing measures of corruption – World Bank worldwide governance indicator Control of Corruption, and the discrepancy between the quantity of luxury wristwatches exported from Switzerland to Ukraine (reported by Swiss statistics) and the corresponding quantity imported by Ukraine from Switzerland (reported by Ukrainian statistics). 相似文献

通过构建改进的知识宽度法测算企业专利质量,并以2007—2016年中国沪深A股上市公司为样本,分析自然人大股东对企业专利质量的影响以及在不同类型企业中其作用的差异性。结果表明,作为“强力监督者”,自然人大股东能够促进企业专利质量提高。但因为其角色由“强监督”转变为“搭便车”,故这种促进作用在国有企业和具有政治关联的企业中并不存在。进一步研究表明,促进作用是通过加强对经理人和研发人员的监督,减少其控制权下投机性创新策略,提升其工作努力程度实现的。研究结论为促进国有企业与民营企业创新能力提升提供相应的政策启示。 相似文献

The M5 competition uncertainty track aims for probabilistic forecasting of sales of thousands of Walmart retail goods. We show that the M5 competition data face strong overdispersion and sporadic demand, especially zero demand. We discuss modeling issues concerning adequate probabilistic forecasting of such count data processes. Unfortunately, the majority of popular prediction methods used in the M5 competition (e.g. lightgbm and xgboost GBMs) fail to address the data characteristics, due to the considered objective functions. Distributional forecasting provides a suitable modeling approach to overcome those problems. The GAMLSS framework allows for flexible probabilistic forecasting using low-dimensional distributions. We illustrate how the GAMLSS approach can be applied to M5 competition data by modeling the location and scale parameters of various distributions, e.g. the negative binomial distribution. Finally, we discuss software packages for distributional modeling and their drawbacks, like the R package gamlss with its package extensions, and (deep) distributional forecasting libraries such as TensorFlow Probability. 相似文献

How and when do prior international experiences lead to global work? A career motivation perspective
While research suggests a link between individuals' prior international experiences and their future participation in global work, we know little about how and the conditions under which this relationship occurs. Drawing on career motivation theory, we conceptualize global identity as a mediator between individuals' density of prior international experiences—defined as the extent to which time spent in culturally novel countries has provided individuals with developmental opportunities—and their global work aspirations, which in turn leads to their global work involvement. Further, this multi-stage mediation model holds mainly when individuals receive positive feedback regarding their intercultural competencies (i.e., cultural intelligence) from their peers. We test our model using a multi-wave multi-source dataset spanning 6 years. We discuss implications for the literatures on prior international experiences and global careers. 相似文献
