We consider the kernel-based classifier proposed by Younso (2017). This nonparametric classifier allows for the classification of missing spatially dependent data. The weak consistency of the classifier has been studied by Younso (2017). The purpose of this paper is to establish strong consistency of this classifier under mild conditions. The classifier is discussed in a multi-class case. The results are illustrated with simulation studies and real applications.

The paper aims to focus on so‐called NoSQL databases in the context of cloud computing.

Architectures and basic features of these databases are studied, particularly their horizontal scalability and concurrency model, that is mostly weaker than ACID transactions in relational SQL‐like database systems.

Some characteristics like a data model and querying capabilities of NoSQL databases are discussed in more detail.

The paper shows vary different data models and query possibilities in a common terminology enabling comparison and categorization of NoSQL databases.

This study investigates whether or not student’s performance, self‐efficacy, and satisfaction are enhanced by the use of an enterprise system as a support tool for learning business process and enterprise systems concepts. The study compares three instructional delivery methods. A traditional instruction method (lecture format plus reading/exercises) serves as the control. The second and third instructional methods are computer‐based methods. In the second method, students receive traditional lecture format with full access to hands‐on an enterprise system transaction exercise. In the third method, students receive traditional lecture format, but also have full access to simulated hands‐on an enterprise system via Web transaction exercises (i.e. ScreenCam movies). A statistically significant difference between‐instructional methods effect is found. Post hoc analysis showed that the simulated hands‐on instruction group’s performance score was significantly higher than that of the control group. There were no other statistically significant differences found, but practical considerations at this learning environment are discussed.

This paper aims to explore a new causal link between market orientation and business performance by introducing dynamic capabilities as a mediator of the relationship between market orientation and competitive advantages, which ultimately determine business performance.

The mediating roles of dynamic capabilities and competitive advantages are tested with a sample of 1,190 Portuguese firms using a structural equation model.

The results confirm the hypotheses regarding the mediating roles of the competitive advantages (differentiation and cost leadership) in the relationship between dynamic capabilities and business performance. Additionally, dynamic capabilities also mediate the relationship between market orientation and competitive advantages.

This study shows that business performance depends on the capacity of firms to collect the best market information on customers and competitors, to disseminate this information throughout their internal structure and ultimately optimize its use to respond appropriately to market challenges and trends. These will provide firms with a set of capabilities and a competitive advantage.

This study provides empirical evidence on the understanding of the relationship between market orientation and performance, through the mediating effects of both dynamic capabilities and competitive advantages.

This paper aims to explore a new causal link between learning, market and entrepreneurial orientations and firms' performance by introducing dynamic capabilities and competitive advantages as mediator variables.

The mediating role of dynamic capabilities and competitive advantages is tested using a sample of 1,190 Portuguese firms, and structural equation models.

It is shown that dynamic capabilities mediate the relationship between the three orientations–learning, market and entrepreneurial–and competitive advantages of differentiation and cost leadership, and both competitive advantages lead to firm's performance. It is also shown that learning orientation is an antecedent of market orientation and entrepreneurial orientation.

This research shows that firm's performance depends on the capacity of firms to learn, innovate, be proactive, take risks and collect the best market data. Indeed, by optimizing the internal management and knowledge dissemination, firms will develop a set of capabilities and competitive advantages that lead to an appropriate response to market challenges.

This study tests the relationship between strategic orientations and firm's performance by taking the mediating effects of dynamic capabilities and competitive advantages into account. This research was conducted in Portugal.

This study aims to investigate the influence of two critical brand extension design components

brand design consistency and category design consistency

on the formation of consumers ' product attitudes and purchase intentions. It also aims to examine the underlying mechanism for attitude formation towards new brand extensions using processing fluency theory and the moderation of brand strength.

A 2 (brand design consistency: high vs low)×2 (category design consistency: high vs low)×2 (brand strength: strong vs weak)×2 (processing fluency: conceptual vs perceptual) between subjects experiment with 642 participants was used to test the proposed hypotheses and model.

Results obtained from SEM and ANCOVA demonstrate that both brand and category design consistencies assert significant effects on new product attitude in brand extensions; however, the relative effect of category design consistency is greater. Further, the effect of category design consistency varies as a function of brand strength, and is stronger for weak brands than for strong brands.

Brand managers should maintain consistency of extension product design with both the parent brand and the new product category, and prioritize the latter for weak brands.

This study integrates brand extension and aesthetics research on prototypicality to formulate and test important research questions, previously unexamined. Further, realistically-rendered product images, allowing both conceptual and perceptual processing, were used in the experiment to provide a better imitation of real product choices – an approach different from most extant brand extension studies, which utilize verbal stimuli.

The authors expand the connotation of the research on the accounting information quality characteristics, provide empirical evidence for the factors of consistency and also help to deepen further their understanding of the economic consequences of ownership concentration and other ownership structures.

Using financial data of Chinese listed companies as samples, coupled with a method to calculate the consistency of the sample enterprises on the corporate level in the 2007–2019 period, the authors studied its impact of ownership concentration on consistency.

The study finds that after controlling other factors, ownership concentration could significantly reduce accounting information consistency. Further research finds that when the executives' shareholding is higher, the reduction effect of ownership concentration on consistency is weaker. After the robustness test, the conclusion remains basically unchanged.

First, maybe there is a limitation of De Franco et al. (2011) method the authors use in China. As some scholars pointed out, the systematic component of returns variation is large in emerging markets (Morck et al., 2000), so it is hard to determine to what extent market stock returns will capture the net effect of earnings. As is mentioned above, there are multiple methods for measuring comparability and consistency, but it is not easy to judge which way is the best. Maybe the authors will have a perfect process in the future. Second, in addition to the factors mentioned in this study's hypotheses, there should be other factors (these include internal factors and external factors) that play moderating role in the impact of ownership concentration on accounting information consistency. The authors have not thoroughly studied the effect of those factors. These limitations all need to be further explored in the future.

The study finds that after controlling other factors, ownership concentration could significantly reduce accounting information consistency, but the reduction will be affected by some other factors related to corporate governance. The new insights from these advances are that the conclusions provide a technical path for management of companies to improve corporate governance efficiency and the quality of accounting information, and also provide more reference and empirical evidence for information users to identify the company's accounting information quality, which contributes to creating a prerequisite for the usefulness of accounting information.

This chapter presents findings from a recently conducted process for obtaining Accounting Advisory Board (AAB) input related to Master of Accountancy curriculum of one university. Board members represent both large and small public accounting firms as well as corporate offices of Fortune 500 companies and non-profit organizations. AAB input includes perceptions of the relative importance of over 160 candidate topics for the courses making up the program’s infrastructure, as well as written comments noting other potential topics and pedagogical approaches to consider. Comparisons of topic rankings reveal a strong level of consistency among Board member types for the traditional accounting courses with structured content, as opposed to those courses involving more systems-related topics or having a wider range of specialized topics. Furthermore, the authors compare Board perceptions regarding topic necessity to those of faculty and note faculty reactions. Specifically, the authors find that faculty ranking consistency with the Board is weak, illustrating the importance of seeking curricular Board input on an ongoing basis. To “close the loop,” faculty incorporated many curriculum changes, involving both the topics to be covered and the overall approach to the course.

This study aims to enrich the current theoretical debate on the growth of start-up firms by extensively investigating the ongoing empirical studies in this research stream. Moreover, this study identifies drivers whose support roles are confirmed in the literature and recommends further research opportunities.

In this study, we analysed the results of 316 empirical studies on start-up firms and growth and also identified and categorised 66 growth drivers. We presented these drivers in three-dimensional charts: 1) the frequency of using each driver in the 316 studies, 2) the consistency of each driver as measured by the number of studies supporting its statistical significance and 3) the net effect (positive or negative) of each driver on growth.

Our analysis compares extant studies on growth drivers and shows some under-explored growth factors of start-up firms.

Both start-up managers and policymakers can benefit from this study. This study provided managers with a fine-grained tool on the main growth drivers and can guide policymakers in supporting policies for start-up firms.

This study provides a rich, fine-grained and coherent picture of several potential growth drivers of start-up firms. Moreover, we extended our analysis to various potential drivers more than previous studies on this topic, thereby providing fruitful insights into the critical growth factors for start-up firms.

Most previous studies have indicated promotional attributes separately (e.g. time pressure, giveaways, price discounts, exclusivity) and found controversial effects. This paper aims to explore how different attributes can be aligned with each other and integrated with different levels of brand strength to influence sales or purchase intention according to the fit logic.

Both field data and controlled experiments are used to understand the effectiveness of promotion configurations. This paper first conducts an exploratory study using qualitative comparative analysis, based on 625 online promotion campaigns. This paper identifies several effective configurations of promotion attributes, leading to the development of two hypotheses. Three experiments are then designed to test the validity of these two hypotheses.

The results show that strong brands should adopt nonmonetary promotion, whereas weak brands should adopt monetary promotion; exclusivity and time limitation should be used separately.

This paper provides empirical insights on how promotion elicits sales in terms of the configuration of promotional attributes and brand strength. This paper examines the integrative effect of types of giveaways, promotion duration and promotion target as well as brand strength on promotion effectiveness. Future research can explore other promotional attributes. This study is a first attempt to introduce and apply the set-theoretic approach to address strategic research issues and inform strategic decisions and managerial actions.

The findings can facilitate marketers’ understanding and predictions of deal recipients’ responses to promotions.

This paper adopts a holistic view to investigate how different promotion attributes interact with one another to stimulate sales. It explores the integrative effect from field data and finds converging evidence through a set-theoretic approach and controlled experiments.
