Mr. Jonathan P. Berger: Gentle Conflations
Sentimentality is a critical aspect of human existence because it is human-natural, agendered, and provides ground for gentle conflation of the domestic sphere and the roles within it. As an artist, I am able to utilize sentimentality to open possibilities and welcome, instead of molest, viewers into contemplation with the assumed norms of domesticity.
With its origins founded in the Age of Enlightenment, sentimentality was a praiseworthy endeavor, one based on intelligence and contemplation. I define sentimentality as the emotional intellect’s way of encoding or decoding the soft emotions surrounding and within objects, people, times or ideas. Soft emotions are those emotions that when positive warm us and when negative nibble away at us. Because of its foundation in our innate emotional intelligence, sentimentality is a human-natural and agendered phenomenon.
I posit that sentimentality can be strategically used to induce gentle conflation between world-representations, especially those located within the domestic. Essentially, world- representations are bundles of facts that are true in some world, be it fictional or non-fictional. Because of their quietness, soft emotions are able to linger mysteriously around and between their source world-representations, blurring their distinctions.
Within my artistic practice I contemplate concepts of labor, love and the fine line between loneliness and solitude found within the domestic sphere by utilizing sentimentality as a tool of gentle conflation
Low Cost Direction Finding with the Electronically Steerable Parasitic Array Radiator (ESPAR) Antenna
Faculty of Engineering and the Built Environment;
School of Electrical and Information System;
MSC DissertationIn this paper, the Electronically Steerable Parasitic Array Radiator (ESPAR) antenna, developed by the Advanced Telecommunications
Research Institute (ATR) in Japan was analyzed to determine its feasibility as a low cost direction finding (DF)
system. Simulations of the antenna were performed in SuperNEC and Matlab was used to determine the direction of arrival
(DOA) using the Reactance Domain multiple signal classification (MUSIC) algorithm. Results show the ideal configuration
has 6 parasitic elements with a diameter of 0.5 . Up to 5 periodic, uncorrelated signals spread 360° in azimuth and above 45°
elevation produce sharp peaks in the MUSIC spectra. Azimuth separations of only 2° at 40 dB are resolvable while signals
arriving with 25% full power are still detectable. For the DOA to be resolved the radiation pattern should be asymmetrical and
hence the reactance set should have a range of unequal values. Comparative results show that the 6 element ESPAR offers excellent
overall performance despite the reduction in cost and is comparable in performance to the 6 element uniform linear array
Heavy bottom squark mass in the light gluino and light bottom squark scenario
Restrictive upper bounds on the heavy bottom squark mass when the gluino and
one bottom squark are both light are based on the predicted reduction of
(the fraction of hadronic decays to pairs) in such a scenario.
These bounds are found to be relaxed by the process , which may partially compensate for
the reduction of . The relaxation of bounds on the top squark and the
scale-dependence of the strong coupling constant are also discussed.Comment: 9 pages, LaTeX, 2 figures, to be submitted to Phys. Lett. B, more

The rotation-magnetic field relation
Today, the generation of magnetic fields in solar-type stars and its relation
to activity and rotation can coherently be explained, although it is certainly
not understood in its entirety. Rotation facilitates the generation of magnetic
flux that couples to the stellar wind, slowing down the star. There are still
many open questions, particularly at early phases (young age), and at very low
mass. It is vexing that rotational braking becomes inefficient at the threshold
to fully convective interiors, although no threshold in magnetic activity is
seen, and the generation of large scale magnetic fields is still possible for
fully convective stars. This article briefly outlines our current understanding
of the rotation-magnetic field relation.Comment: 8 pages, splinter summary of the session "The rotation-magnetic field

Interpersonal online trust in new online social networks
This research proposed a new model for online interpersonal trust based on eight properties of new online social networks. Two elements were found to have significant contributions. These were the ability for users to create an online personal profile where their real identity is disclosed, and the ability to create connections to other online users. The user's innate propensity to trust was also validated as a moderating force on online trust. These results have significant implications for further academic research and online practitioners.Online trust has long been understood as one of the biggest barriers to e-commerce and online business. Various online trust models have been developed and a common theme is the lack of an interpersonal trust component that exists in many real world trust models. Interpersonal trust has been excluded because the internet was considered an impersonal medium. This research argues that the internet has changed to become more personal, and that interpersonal trust is now possible online.The aim of this research was to assist businesses and web designers in understanding drivers of online trust on the new social web. From an academic perspective the aim was to challenge existing online trust knowledge to include interpersonal trust. An online survey was snowball sampled to South African users of Facebook. The survey tested the contribution of eight properties of new online social networks to online trust. The data was analysed using structural equation modelling and the model was found to have a good fit to the data. Further work however is required on the measurement instrument and sampling.Dissertation (MBA)--University of Pretoria, 2012.Gordon Institute of Business Science (GIBS)unrestricte
