Corporate risk disclosure by UK firms: trends and determinants

Abstract: This study explores risk disclosure practice using content analysis of 156 annual reports prepared by 52 UK listed companies in three different periods (1998, 2001 and 2004). The study relates the extent of risk disclosure to firm-specific characteristics. The study found, a trend of increasing amounts of risk disclosure in the annual report over the six-year period influenced by accounting regulation and accounting institutes' recommendations. US dual listing and involvement in heavy industry are significantly and positively correlated with the level of risk information disclosed by the sampled companies. Risk disclosure is not related to size or leverage.

Lightweight cryptography methods

Abstract: While our conventional cryptography methods, such for AES (encryption), SHA-256 (hashing) and RSA/Elliptic Curve (signing), work well on systems which have reasonable processing power and memory capabilities, these do not scale well into a world with embedded systems and sensor networks. Thus lightweight cryptography methods are proposed to overcome many of the problems of conventional cryptography. This includes constraints related to physical size, processing requirements, memory limitation and energy drain. This paper outlines many of the techniques that are defined as replacements for conventional cryptography within an Internet of Things (IoT) space and discuss some trends in the design of lightweight algorithms.

Organizational culture in knowledge creation, creativity and innovation: Towards the Freiraum model

Abstract: This paper draws on findings from an in-depth case study of practices related to the meeting of organizational goals pertinent to knowledge creation, creativity and innovation performance. Overall a mixed methods approach that used both quantitative and qualitative data was adopted in empirical research conducted within a large German manufacturing firm. A quantitative analysis of survey data highlighted factors necessary to nurture an environment conducive to knowledge creation, creativity and innovation. The organization should: be open to change; encourage and value free communication and new and/or unusual ideas; tolerate mistakes; and nurture intrinsically motivated staff. It should be supported by leaders who promote these characteristics as shared values, while challenging and empowering their staff to generate new ideas in a drive to further innovation. Further analysis of focus group and interview data in the same case study identified three main determinants that underpin knowledge creation and creativity: (1) structured 'space' that creates expertise and experience of individuals while working in routine; (2) willingness to innovate - individuals' propensity to experiment with ideas, even at risk of failure; and (3) authorized and dedicated 'space' designated specifically for individuals to explore new ideas ('Freiraum'). These findings have contributed to the development of a new articulation of the organization of creativity and innovation. It draws on established concepts from the domain of knowledge and creativity management, and extends these to deepen our understanding of how aspects of organizational culture, including leadership and social conditions, influence organizational performance in terms of (1) improving knowledge creation processes related to creativity, and (2) fostering innovation.
