Posttranscriptional regulation with regard to cleavage factor I (CFI) associated alternative polyadenylation and methyltransferase A (MTA) assisted m6A modifications in Arabidopsis thaliana
… polyadenylation machinery. Cleavage factor I (CFI) is a complex associated with APA and well-studied in humans, but not in Arabidopsis. N6-methyladenosine (m6A) is one of the most frequently observed RNA modifications, which is established by methyltransferase A (MTA) and other m6A writer …

Evaluating modern defenses against control flow hijacking
… Integrity (CPI) and Control Flow Integrity (CFI) have their weaknesses. In this thesis, we present attacks that expose the fundamental weaknesses of CPI and CFI. CPI promises to balance security and performance by focusing memory safety on code pointers thus preventing most control-hijacking …

A feasibility study exploring the impact of practising compassion-focused imagery exercises online on eating disorder symptomatology in a community sample
… online self-compassion interventions, such as CFI-online, may be an accessible, resource-efficient and beneficial intervention for adults in the community with ED-symptoms. However, the feasibility of CFI-online would need to be explored before conducting larger research in the area. To this …

Analysis of defenses against code reuse attacks on modern and new architectures
… about the efficacy of control-flow-integrity (CFI), a defensive technique which attempts to prevent such attacks by ensuring that every control flow transfer corresponds to the original intent of the program author. Although this problem is in general undecidable, most programs running on …

Trace-based hardware control flow signature checking
… One such advancement, control-flow integrity (CFI), offers immunity to code-reuse attacks but slows down software that enforces CFI. In this work, we present a hardware monitor design that utilizes hardware support for instruction tracing to detect code-reuse attacks. The monitor is small in …

Inter-functional citizenship behaviour: A novel scale validated for the integration of Research and Development and Intellectual Property team members
… aligned and that cross-functional integration (CFI) from the process- perspective is achieved. However, findings about the benefits of CFI are still uncertain, poorly understood, arouse controversy in academia and do not capture the holistic problem of CFI in R&D processes. Only a few …

Make Some Noise: Methods for Generating Data from Imperfect Factor Models
… of fit indices like the Comparative Fit Index (CFI) should also be used. Unfortunately, the TKL, CB, and WB model-error methods do not provide a way to specify multiple target fit indices. To address this issue, I proposed an optimization procedure that allows users to specify either a target …

High-dimensional Quantum Key Distribution with Frequency Encoding
… of the conjugate-Franson interferometer (CFI). We show that the CFI visibility can certify time-energy entanglement and detect the biphoton spectral phase, which Franson interferometry and Hong-Ou-Mandel interferometry are incapable of. In the final part of this thesis, we show an …

Effects of Organizational Climate, Feedback-Seeking Environment and Innovation Characteristics on the Implementation of a 360-Degree Feedback System
… Fit Index (NNFI) = .95, Comparative Fit Index (CFI) = .96; Root Mean Square Error of Approximation (RMSEA) = .16; using maximum likelihood estimates: NNFI = .37, CFI = .48; RMSEA = .18) thus failing to provide support for the hypothesized model. Limitations of the present study and suggestions …

A systematic analysis of defenses against code reuse attacks
… enforced by proposed control flow integrity (CFI) systems. We model the behavior of these systems using a graph search. We also develop several code reuse payloads that work within the control flow graph enforced by one proposed CFI defense. Our findings illustrate that the defenses we …

Perspectives on effectiveness: what works in a juvenile fire awareness and intervention program?
… (FRI) and children’s firesetting interview (CFI). Children’s recidivism was also prospectively followed-up for 12 months. Pre and post findings on the FRI suggested that all JFAIP clients benefited from the intervention. From the parent’s perspective, lower fire-specific risk factors were …

Individualism/Collectivism, Psychological Processes, and Styles of Conflict Resolution
… styles (dominating and compromising) revealed a CFI= .96, and CFI= .94 respectively. Specifically, in support of the hypotheses, it was found that the dominating form of conflict resolution was a function of the individualist value orientation as well as the perception of controllability, while …
