We commemorate the 50th anniversary of Ball and Brown [1968] by chronicling its impact on capital market research in accounting. We trace the evolution of various research paths that post–Ball and Brown [1968] researchers took as they sought to build on the foundation laid by Ball and Brown [1968] to create a body of research on the usefulness, timeliness, and other properties of accounting numbers. We discuss how those paths often link back to the groundwork laid and questions originally posed in Ball and Brown [1968].  相似文献

被动式传感器目标跟踪是多传感器多目标跟踪领域的一个重要研究方向。针对三被动式传感器多目标定位系统全局最优数据关联的三维分配问题,在允许传感器漏检和虚警的情况下,通过分析拉格朗日松弛算法,提出一种假定真实目标的快速收敛算法。该算法通过粗关联假定真实目标并重新修改代价矩阵,然后进行细关联,使得拉格朗日松弛算法在保证关联精度的前提下有效地提高了收敛速度。理论分析和实验结果表明,该算法提高了数据关联的速度,并在一定程度上提高了关联准确率。  相似文献

This paper reviews some recent blockchain‐based applications for information capture, distribution and preservation. As part of that review, this paper examines two key concerns with current blockchain designs for accounting and supply chain transactions: data independence and multiple semantic models for the same information distribution problem. Blockchain applications typically integrate database, application and presentation tiers all in the same ledger. This results in a general inability to query information in the ledger and other concerns. Further, since most applications appear to be private blockchain applications, there is a concern of agents needing to accommodate multiple blockchains depending on who their trading partners are and what they request. Finally, this paper uses a distributed database to design a ‘blockchain‐like’ system for virtual organizations.  相似文献

Consumers often imagine what it would be like to own a new product. Does engaging in such thoughts on desired future impact consumers’ purchase intentions, and if so, what is the underlying process? This study sets out to investigate the posed questions by assessing self‐regulatory strategies consumers employ upon pondering on a desired future. Based on Oettingen’s fantasy realization model, the authors take a comparative approach of two modes on desired future—mental contrasting and indulging—en route to purchase intentions. In mental contrasting, an individual juxtaposes a desired future with his/her present reality, whereas, indulging is simply envisioning a desired future. Contingent upon the perceived likelihood of fantasy realization, consumers in the mental‐contrasting condition adjust their level—that is, high (low) for high (low) feasibility case—in goal commitment as well as in energization to achieve the desired future. In contrast, consumers in the indulging condition engage in moderate level of goal commitment—irrespective of the likelihood of fantasy realization. In a series of experiments, this study scrutinizes the fantasy realization model in context of attribute alignability/nonalignability, uncertainty in attribute meaningfulness and novelty, technological and psychological obsolescence en route to affecting the consumers’ product purchase/upgrade intentions. Conceptually, this study is the first to adapt the fantasy realization model to the marketing context, and the authors provide managerial implications of their key findings.  相似文献

Given the importance of communication in the realm of corporate associations, this study analyzes the roles that communication strategies play in the formation of corporate associations. The study examines (1) whether particular types of associations (corporate ability or corporate social responsibility associations) can be developed through CA- or CSR-based communication strategies, and (2) the relative effectiveness of these two association types at amplifying favorable consumer responses across three different industries (consumable goods, durable goods, and stigmatized goods). An experiment was conducted to test the proposed model with six Fortune 500 companies. The results demonstrate that communication strategies can effectively facilitate a particular type of association. Differing levels of association effectiveness were found within each industry. For the consumable goods industry, CA associations are found to be more effective than CSR associations. For the durable goods industry, CSR associations are more influential at enhancing consumer attitudes and purchase intent than CA associations, while CA associations have a larger impact on supportive communication intent. In the case of the stigmatized industry, CSR associations play a determinant role in fostering positive consumer responses. This study provides managers and communication specialists with more concrete guidance for choosing a particular corporate positioning and communication strategy.  相似文献

加快实施最严格水资源管理制度的重要目标是形成以节水为目标的新的社会运行机制和社会治理模式。农民在农业灌溉中自发形成的用水组织是这一变革中的重要社会力量。通过对农民用水协会特征的分析,认为在"水权配置"的视角下,发展与规范农民用水组织,变原有农业用水过程中的行政管控为社会治理,是建立农业"节水型"社会并支持其良好运行的重要保障,并就如何健全农民用水组织的内部治理结构、克服农民用水组织自身的消极因素提出了建议。  相似文献

ABSTRACT

Alumni communication is vital in sustaining the relationship between alumni and their alma maters. This research investigated four cohorts of alumni, and their intentions to use a range of traditional and digital communication channels, including social media. An online questionnaire was sent to 8060 alumni and resulted in 595 usable responses, yielding a 7% response rate. The research results showed that alumni have the highest intentions to use the alumni e-newsletter and the alumni Website and the lowest intentions to use social media, e.g., Twitter, Instagram, and YouTube. Among alumni cohorts, significant statistical differences in their intentions to use these communication channels were identified. Given our findings, alumni communication staff are encouraged to leverage different communication channels targeting alumni in different age groups.  相似文献

This paper explores the relative influence of the accounting academy and accountancy professional associations in the debate concerning the profile and quality of accounting education research. This research analyses 13 semi-structured interviews undertaken with members of key accounting professional associations in Australia, New Zealand (ANZ) and the United Kingdom and Ireland (UKI). The paper makes a theoretical contribution by the novel application of the institutional logics theory to the literature concerning professional accounting associations (PAAs) demonstrating the dominant commercial logic of the education function and the more traditional fiduciary logic of the technical function. The research finds that the primary stakeholders in the professional accounting curriculum development model are the PAAs and employers, whilst the accounting academy is relatively absent. The relative independence of the education and research and technical functions within PAAs is also identified: academic research and technical activity has little influence on professional education and vice versa. However, PAAs’ funding of academic research is common across all four countries for brand recognition and in some instances to influence policy rather than informing the professional curriculum.  相似文献

This study investigates the effect of ingredient images on implicit tasty–healthy associations for packaged products. An implicit association test (IAT) with 106 respondents reveals the impact of repeating ingredient images on the implicit healthy = tasty intuition; fewer ingredient images are linked to a stronger intuition. This study also considers explicit product packaging preferences and the number of ingredient images depicted. The implicit intuitions affect explicit preferences, such that packages depicting few ingredient images are preferred over those depicting many ingredient images for healthy products, but no significant effects emerge for unhealthy products.  相似文献

在交通场景中采用一些预警措施能够有效地减少交通事故发生。例如,对车辆轨迹进行跟踪并预测车辆的驾驶行为,就是一个常用的预警方法。在对车辆进行跟踪的过程中,数据关联是很重要的部分,它可以对车辆的观测点和轨迹进行关联,从而更新车辆的轨迹,完成跟踪过程。在此背景下,提出了一种新的数据关联算法,即k近邻联合概率数据关联算法(k Nearest Neighbor-Joint Probability Data Association,kNN-JPDA)。实验结果表明,该算法能够较好地解决在交通场景下车辆数据的数据关联问题,在精度以及运行效率方面都有所提高。  相似文献
