Published incidents and their proportions of human error

The file attached to this record is the author's final peer reviewed version. The Publisher's final version can be found by following the DOI link.Purpose - The information security field experiences a continuous stream of information security incidents and breaches, which are publicised by the media, public bodies and regulators. Despite the need for information security practices being recognised and in existence for some time the underlying general information security affecting tasks and causes of these incidents and breaches are not consistently understood, particularly with regard to human error. Methodology - This paper analyses recent published incidents and breaches to establish the proportions of human error, and where possible subsequently utilises the HEART human reliability analysis technique, which is established within the safety field. Findings - This analysis provides an understanding of the proportions of incidents and breaches that relate to human error as well as the common types of tasks that result in these incidents and breaches through adoption of methods applied within the safety field. Originality - This research provides original contribution to knowledge through the analysis of recent public sector information security incidents and breaches in order to understand the proportions that relate to human erro

Strategic sustainability and financial performance: exploring abnormal returns

The ongoing empirical debate about whether SRI is associated, if anything, with subpar or surpassing financial performance is characterized by a somewhat indistinct focus and the infeasibility of tapping the full potential of existing models. By indistinct focus, we mean an analysis based on an aggregation of a myriad of SRI factors that potentially affect a firm's financial performance. The inability of taking full advantage of existing models is reflected by the fact that studies with European data have not been able to comprehensively account for systematic risk tilts. This paper presents a portfolio analysis that overcomes these issues by analyzing a distinct selection of small and innovative firms. We argue that both their strategic implementation of Corporate Social Responsibility and the general growth in socially responsible investments (SRI) lend themselves to an explanation for positive abnormal returns of this portfolio. We account for the idiosyncratic investment style of SRI by introducing a comprehensive pan-European risk-adjusted portfolio analysis based on the Carhart four-factor model. A novel propensity score matching method in conjunction with the estimation of structural models completes the conventional robustness checks in the literatur

Tsetse and human trypanosomiasis challenge in south eastern Uganda

Pièges pyramidaux (8000) ont été mis en place contre #Glossina fuscipes fuscipes afin de lutter contre la maladie du sommeil à #Trypanosoma rhodésiense dans le Busoga. Dans le but de comprendre les modalités du contact homme/mouche, la récolte des données sur la densité, la distribution spatiale et la mobilité des mouches, ont été mis en relation avec la dynamique de la transmission de la trypanosomiase humaine dans le Bugosa. Comme pour #T. gambiense$, peu de corrélations entre la densité globale de mouche et l'incidence de la maladie ont été trouvées. Cependant, des observations de terrain avec un enregistrement daté des mouvements saisonniers des hommes et des animaux dans des habitats favorables aux mouches demeure la clé de la compréhension de la transmission de la maladie.

Real-time inline monitoring of zeolite synthesis by Photon Density Wave spectroscopy

The formation process of zeolite A (Linde Type A) was monitored inline at 1.5 L scale by Photon Density Wave (PDW) spectroscopy as novel process analytical technology for highly turbid liquid suspensions. As a result, the reduced scattering coefficient, being a measure for particle number, size, and morphology, provides distinct process information, including the formation of amorphous particles and their transfer into crystalline zeolite structures. The onset and end of the crystallization process can be detected inline and in real-time. Analyses by powder X-ray diffraction and electron microscopy, based on a sampling approach, support the interpretation of the results obtained by PDW spectroscopy. In addition, the influence of the molar water content was investigated, indicating a linear increase of the time needed to reach the end of the zeolite A crystallization with increasing molar water content. Further experiments indicate a strong influence of the silica source on the course of the crystallization. The applicability of PDW spectroscopy under even more demanding chemical and physical conditions was investigated by monitoring the synthesis of zeolite L (Linde Type L)
