Cybersecurity data science: an overview from machine learning perspective

Abstract: In a computing context, cybersecurity is undergoing massive shifts in technology and its operations in recent days, and data science is driving the change. Extracting security incident patterns or insights from cybersecurity data and building corresponding data-driven model, is the key to make a security system automated and intelligent. To understand and analyze the actual phenomena with data, various scientific methods, machine learning techniques, processes, and systems are used, which is commonly known as data science. In this paper, we focus and briefly discuss on cybersecurity data science, where the data is being gathered from relevant cybersecurity sources, and the analytics complement the latest data-driven patterns for providing more effective security solutions. The concept of cybersecurity data science allows making the computing process more actionable and intelligent as compared to traditional ones in the domain of cybersecurity. We then discuss and summarize a number of associated research issues and future directions. Furthermore, we provide a machine learning based multi-layered framework for the purpose of cybersecurity modeling. Overall, our goal is not only to discuss cybersecurity data science and relevant methods but also to focus the applicability towards data-driven intelligent decision making for protecting the systems from cyber-attacks.

The cognitive neuropsychology of delusions

Abstract: After reviewing factors implicated in the generation of delusional beliefs, we conclude that whilst a perceptual aberration coupled with a particular type of attri-butional bias may be necessary to explain the specific thematic content of a bizarre delusion, neither of these factors, whether in isolation or in combination, is sufficient to explain the presence of delusional beliefs. In contrast to bias models (theories which explain delusion formation in terms of extremes of normal reasoning biases), we advocate a deficit model of delusion formation–that is, delusions arise when the normal cognitive system which people use to generate, evaluate, and then adopt beliefs is damaged. Mere bias we think inadequate to explain bizarre delusions which defy commonsense and persist despite overwhelming rational counter-argument. In particular, we propose that two deficits must be present in the normal cognitive system to explain bizarre delusions: (1) there must be some damage to sensory and/or attentional-orient-ing mechanisms which causes an aberrant perception–this explains the bizarre content of the causal hypothesis generated to explain what is happening; and (2) there must also be a failure of normal belief evaluation–this explains why a hypothesis, implausible in the light of general commonsense, is adopted as belief. This latter deficit occurs, we suggest, when an individual is incapable of suspending the natural favoured status of direct first-person evidence in order to critically evaluate hypotheses, given equal pri-ority whether based on direct or indirect sources of information. In contrast, delusions with ‘ordinary’ content may arise when a single deficit of normal belief evaluation occurs in the context of an extreme (but normal) attentional bias, thus causing failure to critically evaluate hypotheses based on misperceptions and misintrepretations of ambiguous (but ordinary) first-person experience.

Measuring and managing sustainability performance of supply chains: review and sustainability supply chain management framework

Abstract: Purpose – The purpose of this paper is to discuss what a fully sustainable supply chain might look like and the consequences that can be drawn from this view. Also, it develops a practical approach towards sustainability supply chain performance measurement and management. The paper develops an analytical framework for the assessment of approaches for the measurement and management of sustainability performance of supply chains (SPSCs). Little research has been conducted on the issues, existing methods and possible approaches to measure and manage SPSCs. Design/methodology/approach – Literature review and conceptual development of framework. Findings – The paper develops an analytical framework for the assessment of approaches for the measurement and management of SPSCs. Existing approaches discussed in the vein of improving supply chains and increasing recycling are examined in the light of our framework, and areas to extend the research on sustainability performance measurement and management are identi...

Dragon Multinational: A New Model for Global Growth

Abstract: The conventional view of globalization sees it as a process driven by giant firms from the Triad regions of North America, Europe, and Japan, shaping the world in their own image. This book contests such a view, describing the extraordinary success of a handful of multinationals from the "Periphery" in globalizing their operations extremely rapidly. Focusing on Acer, the Taiwanese IT company; the Hong Leong hotel group of Singapore; Ispat International in steel; Cemex of Mexico in cement; and Li and Fung from Hong Kong in contract manufacturing, Matthews demonstrates that these firms have been able to utilize strategies of international linkage and leverage to accelerate their global coverage. He contends that they are pioneers of a new kind of global firm, indicators that the global business civilization being created in the 21st century is like to be pluralistic and diverse, offering unprecedented opportunities for firms that know how to enmesh themselves in global networks.
