Spear-Phishing Susceptibility Stemming From Personality Traits
This study explores the psychological aspects of social engineering by analyzing personality traits in the context of spear-phishing attacks. Phishing emails were constructed by leveraging multiple vulnerable personality traits to maximize the success of an attack. The emails were then used to test several hypotheses regarding phishing susceptibility by simulating a series of spear-phishing campaigns inside a software development company. The company’s employees underwent a standard Big Five personality test, four different phishing emails over four weeks, and cybersecurity training. The results were aggregated before and after the cybersecurity course, and binary logistic regression analyses were performed at each phase of the phishing attack. The results show that personality traits correlate with phishing susceptibility under certain circumstances and pave the way for new methods of protecting individuals from phishing attacks
Aberrant cell divisions in root meristeme of maize following exposure to X-rays low doses compared to similar effects of 50 Hz electromagnetic exposure
The response of maize to radiation exposure was investigated by two cytogenetic methods considering the importance of the geno-toxic effect for environmental and agricultural purposes. Uniform genophond seeds, freshly germinated, were exposed to relatively low radiation doses using a radiotherapy X-ray applicator from a hospital irradiation device and to a 50 Hz electromagnetic field with about 10 mT magnetic induction (generated within laboratory assembled electromagnetic coils). Radicular meristeme tissue aliquots were prevailed for cytogenetic investigation based on microscopic observations and cell counting. Microscope slides were prepared following a specific procedure (squash technique and Feulgen method based on modified Carr reactive coloration). Mitotic index as well as chromosomal aberration percentage were calculated for more than 30,000 cells taken into account. From a qualitative viewpoint, chromosomal aberrations such as interchromatidian bridges, lagging and expelled chromosomes and multipolar divisions were evidenced - no distinct situation for either ionizing radiation or electromagnetic field being identified. The main quantitative difference consisted in the increased mitotic index for electromagnetic exposure increased times compared with the diminished mitotic index in the case of low X-ray doses
Techniques of Aquisition, Processing and Validation of Satellite Images
Within the European Politics for Geographic Information, geographic information represents a complex part in continuous development of informational society having a wide range of applicability. This can be categorized into: spatial, geographic information and descriptive, qualitative information. These two types of data can be integrated in the same information management system by a Geographic Informational System. (GIS)
