Humans in cyber resilience: managerial and operational opportunities
Full text linkThe hyper-connected environment of today has resulted in a substantial boost in productivity, efficiency, and system integration, but it has also raised the number of possible threats. Organizations are increasingly reliant on data and information from their interconnected systems, making them exposed to a variety of cyber attacks. Cyber threats have an impact on the continuity of their company operations, the loss of confidential information, reputational harm, and possibly the safety of their employees. Cyber attacks have become more sophisticated, raising awareness of the importance of not limiting the design of cybersecurity practices to detection and protection phases, but of considering the ability to respond, recover, and thus withstand cyber incidents as fundamental from a cyber resilience perspective.
This thesis is based on four comprehensive research objectives. First, the thesis sheds light on the definitions and topics related to cyber resilience and cyber security. These analyses set the groundwork and motivate the challenges addressed in the thesis. The second part of the thesis then focuses on the need to go beyond purely technical aspects when managing cyber resilience by integrating organizational and human aspects. The debate is developing as to which is the human role in cyber socio-technical systems. Specifically, the aim is to identify new managerial and operational opportunities to raise the positive role of humans in increasing the cyber resilience of the cyber socio-technical systems in which organizations operate today.
The thesis maps the human factors involved in cybersecurity, identifying under what circumstances they can be a driver or a barrier to it, helping practitioners prioritize and achieve cyber resilience goals. Second, tools that can be used as external leverage to improve human integration with cyber socio-technical systems are presented. Outsourcing strategies for cybersecurity management are discussed. In addition, a reference architecture and taxonomy for intelligent digital assistants is developed and a proactive agent to support employees in managing cybersecurity issues is tested.
In sum, this thesis adds both theoretical and practical contributions to the field of cyber resilience, focusing on managerial and operational opportunities. The thesis has a publication-based structure
Peritoneal sarcomatosis 5 years after laparoscopic morcellation of uterine leiomyoma
No full textIn 2011, a 40-year-old woman underwent laparoscopic myomectomy with intraabdominal morcellation. Histology report showed leiomyoma without atypia, necrosis, or mitosis. In 2016, she complained of left lower quadrant pain; ultrasound examination revealed a left hypogastric mass in the site of trocar placement. Percutaneous biopsy results showed a low-grade endometrial stromal sarcoma (LGESS). At laparoscopy, we observed: multiple nodules on uterine serosa, left annex, vesical peritoneum (Figure 1), Douglas pouch (Supplementary Video1), previous left pelvic trocar site (Figure 2), greater omentum (Figure 3), and right/left diaphragm
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Laparoscopic radical hysterectomy for malignant indications: Laparoscopic trachelectomy
No full textCervical cancer is the third most common female cancer and the fourth leading cause of female cancer death worldwide [1]. Approximately 15 % of all cervical cancers are diagnosed in women under the age of 40 years who wish to preserve their fertility [2, 3]. For these reasons, although radical hysterectomy with lymph node dissection represents the standard treatment for early-stage cervical cancer, alternative surgical approaches able to spare reproductive organs have been develope
Multigranular scale speech recognition: tehnological and cognitive view
Full text linkWe propose a Multigranular Automatic Speech Recognizer. The hypothesis is that
speech signal contains information distributed on more different time scales.
Many works from various scientific fields ranging from neurobiology to speech
technologies, seem to concord on this assumption. In a broad sense, it seems
that speech recognition in human is optimal because of a partial
parallelization process according to which the left-to-right stream of
speech is captured in a multilevel grid in which several linguistic analyses take
place contemporarily. Our investigation aims, in this view, to apply these new
ideas to the project of more robust and efficient recognizers
