Understanding the Feature Space and Decision Boundaries of Commercial WAFs Using Maximum Entropy in the Mean.

The security of a network requires the correct identification and characterization of the attacks through its ports. This involves the follow-up of all the requests for access to the networks by all kinds of users. We consider the frequency of connections and the type of connections to a network, and determine their joint probability. This leads to the problem of determining a joint probability distribution from the knowledge of its marginals in the presence of errors of measurement. Mathematically, this consists of an ill-posed linear problem with convex constraints, which we solved by the method of maximum entropy in the mean. This procedure is flexible enough to accommodate errors in the data in a natural way. Also, the procedure is model-free and, hence, it does not require fitting unknown parameters.

What type of client do you need? The brand value co-creation in the banking sector.

Service-dominant logic established that for the success of service industries, it is vital to acknowledge the customer as an active agent in the commercial ecosystem. To carry it out, the consumer must participate in value creation. The resource integration theory exposes the importance of recognizing the customer as an agent capable of improving the company's competitive advantage. It is only necessary for the participants to perceive benefits to make their resources available and integrate them into the co-creation process. This study aims to find the key customer-based factors that influence the brand value co-creation (VCC) process in the banking sector, analyzing the dynamics in different customers across national cultures and idiosyncrasies. In this paper, we analyze the potential heterogeneous idiosyncrasy of customers and how it leads to becoming more engaged in the co-creation process. Quantitative research was performed in five countries, obtaining a total of 2,029 valid questionnaires where latent profile analyses and ANOVAs were performed to identify and describe the latent profiles (LPA) of consumer co-creators of brand value. Afterward, a PLS-SEM was performed to test the research model in each segment. The results show four different profiles of customer co-creators of brand value, from non-co-creators (detractors), skeptical and neutral, to customers committed to co-creating brand value with their banks. The results indicate that detractor customers lack the motivations and resources to carry out co-creation behaviors. On the other hand, creativity and connectedness were crucial for customers co-creators of value. To the authors' understanding, no studies have used latent segmentation to find the profiles of customer co-creators of brand value.

Purchase intention and purchase behavior online: A cross-cultural approach.

This article aims to explore the key factors on e-commerce adoption from elements of social psychology, such as attitude, subjective norms, perceived behavioral control, ease of use and perceived usefulness, introducing the study of non-traditional elements like buying impulse, compatibility, and self-efficacy in online stores, contrasting relationships in a cross-cultural environment. The proposed model is tested from quantitative research with a sample of 584 online consumers in Colombia and Spain. The following statistical analyses were conducted: CFA, structural equations, measurement instrument invariance, and multi-group analysis with EQS 6.3 software. The study reveals that self-efficacy in online stores is a key factor in adopting electronic commerce above the cultures studied. Also, there is significant evidence that proves the moderating effect of national culture on several relationships of the model proposed. Results highlight the importance of national culture to understand impulsive buying behavior. The article presents several considerations toward the main elements to generate online purchase intention among consumers in an emerging country and finds substantial differences with consumers in a developed country. Practical implications are made for companies to adopt online channels and expand internationally.
