In January 2015, three terrorists killed 17 people in Paris. In a time in which fears of immigrants and Muslims are spread in Europe and right wing movements are gaining support, this event built a foundation for actors of centre right and right wing parties to use the attacks in their favor. The aim of this study was to investigate how French and German media reported on the attacks, which measures were suggested in response to the attacks by political actors and how media facilitated possible securitization moves. By conducting this case study for which French and German newspaper articles were collected through the database Lexis Nexis and analyzed through content and discourse analysis, a contribution to security studies was made. The analytical framework used, Securitization Theory with an integration of Framing Theory, proved valuable as it indicated that media, by framing the issues connected to the Paris Attacks in favor of securitizing actors, facilitated securitization moves. Securitizing actors were mainly centre right politicians in Germany and the French right wing party National Front. Furthermore, German newspaper articles on the attacks outnumbered French newspaper articles, indicating the high level of media attention to the key event. However, the role of Islam was mentioned in more French newspaper articles than it was the case in German newspapers. Overall, terrorism and Islam were portrayed as a threat to the referent objects of the West, its citizens and values, fostering an essentialist and dichotomist understanding of the West and Islam.

Silicon physical unclonable functions (PUFs) are security primitives relying on the intrinsic randomness of IC manufacturing. Strong PUFs have a very large input-output space which is essential for secure authentication. Several proposed strong PUFs use timing races to produce a rich set of responses. However, these PUFs are vulnerable to machine-learning attacks due to linear separability of the output function resulting from the additive nature of timing delay along timing paths. We introduce a novel strong silicon PUF based on the exponential current-voltage behavior in subthreshold region of FET operation. This behaviour injects strong nonlinearity into the response of the PUF. The PUF, which we term subthreshold current array (SCA) PUF, is implemented as a two-dimensional n x k transistor array with all devices subject to stochastic variability operating in subthreshold region. Our PUF is fundamentally different from earlier attempts to inject nonlinearity via digital control techniques like XORing the outputs of PUF and using feedforward structures, which could also be used with SCA-PUF. Voltages produced by nominally identical arrays are compared to produce a random binary response. SCA-PUF shows excellent security properties. The average inter-class Hamming distance, a measure of uniqueness, is 50.3%. The average intra-class Hamming distance, a measure of response stability, is 0.6%. Crucially, we demonstrate that the introduced PUF is much less vulnerable to modeling attacks. Using a machine-learning technique of support-vector machine with radial basis function kernel for optimum nonlinear learnability, we observe that the information leakage (rate of error reduction with learning) is much lower than for delay-based PUFs. Specifically, over a wide range of the number of observed challenge-response pairs, the error rate is 3-35x higher than for earlier designs. / text

South Africa, after ten years of democracy should have been a secure and peaceful place. It has however developed into a cesspool of violence. Violent crime is currently a common factor in everyday life. It is especially the severe nature of the assault and mutilation that makes violent crimes so traumatizing. The aim of this study is to identify the need for counselling of these traumatized victims of violent crimes and to design a future strategy for the possible application by pastoral counsellors and ministers to support and minister these violent crime victims. The method of approach according to which this study was done, is the practical theological model of Getz where the different perspectives was studied through lenses. From the above mentioned survey it became evident that violent crimes are still increasing and the subsequent trauma received very little attention up to now. Empirical research clearly suggested that although these victims needed pastoral counselling, they did not receive any form 293 of counselling. With the help of the pastoral counsellor these violent crime victims can overcome trauma. Pastoral counselling to the traumatized victim of violent crime is carried out by the counsellor, a called servant of God, using Scripturally founded pastoral skills in counselling, in this way creating a pastoral relationship. The aim is to lead the counselee towards growth in belief in God in order to handle this through faith. The conclusion reached after the research had been taken is that traumatized victims of violent crimes did not receive counselling from their ministers. The trauma that is caused by violent crimes has a fierce impact on victims and this research, with the aid of the pastoral model, might help victims to carry on their daily lives in honour of God. / Thesis (Ph.D. (Pastoral))--North-West University, Potchefstroom Campus, 2005.

Narcolepsy is a disabling sleep disorder that is characterized by persistent sleepiness, and cataplexy – an involuntary loss of waking muscle tone. Cataplexy and narcolepsy are caused by the loss of hypocretin containing neurons in the hypothalamus. However, it is hypothesized that dopamine is also involved in sleep and motor control and plays a role in cataplexy. This study investigated how manipulating dopamine affected sleep and cataplexy in narcoleptic mice devoid of hypocretin. We used d-amphetamine to increase endogenous dopamine levels and quinpirole (D2 agonist) to agonize D2 receptor sites. Amphetamine promoted wakefulness while decreasing sleep in wild-type mice, but was less effective in narcoleptic mice. Amphetamine also reduced cataplexy as well as sleep attacks (an indicator of sleepiness) in narcoleptic mice. Quinpirole had no effect on sleep or wakefulness; however, it potently increased cataplexy without affecting sleep attacks in narcoleptic mice.

The purpose of the study was to determine what spectator security measures have been taken by collegiate football stadium operators because of or as a direct result of the terrorist attacks on September 11, 2001. Subjects consisted of Assistant Athletic Directors, Associate Athletic Directors, Directors of Football Operations, an Associate Director, a Coordinator of Football Operations, an Executive Associate Athletic Director, and a Police Sergeant. Percentages were used to analyze the data. A self-constructed survey was designed to asses the spectator security measures that had changed within the Big Ten and MidAmerican Conference football stadiums. The survey was administered using the inQsit® program developed at Ball State University. An on-line survey was sent to 25 universities: 11 universities for the Big Ten and 14 universities in the MidAmerican Conference. Data was collected concerning one research question.With a return rate of 64%, 100% of the universities indicated changing their security measures as a direct result of September 11, 2001. Respondents reported an increase in book bag searches (56%) and body searches (25%). Respondents also identified, as security changes, an increase in law enforcement during football games (100%), restricting air space (94%), notifying ticket buyers ahead of time of security changes (81 %) and the event-operating budget was affected, and changes were made regarding items allowed to be carried into the stadium. / School of Physical Education
