Artificial light is an important and necessary part of our urban environment, but has become a threat to biodiversity. It can have substantial direct and indirect effects on populations of all kinds of organisms. While light attraction in bats and moths has been well studied other organisms such as Trichoptera have been largely neglected, despite Trichoptera being one of the most abundant insect orders in freshwater systems. The light attraction of Trichoptera was studied through seasonal data from three different locations in Sweden. The data was examined through meta- and regression analyses to compare catches in light traps and passive traps. The use of relative abundances excluded bias from the species with large populations, and the difference in individuals caught between passive traps and light traps. The results indicated that artificial light could affect Trichoptera populations. Unlike moths, female Trichoptera were more attracted to light than males and attraction to light varied between species. In both cases, size dimorphism could explain the variation. Day-, evening- and night-active species were all attracted to light, but the latter more so. Research has shown that a false flight activity can occur in day-active Trichoptera when a lamp is lit during night, which could explain the capture of day- and evening-active species in a light trap. In all, artificial light could alter Trichoptera populations, changing sex ratios and species composition. This impact should be considered when erecting light sources near waterways.

M.A. (Clinical Psychology) / Initial romantic attraction is a universal social phenomenon and can broadly be defined as the awareness for the potential of a long-term romantic relationship or the positive regard an individual has for another. In essence, it is the initial feelings an individual has toward a potential mate. Due to the significance of romantic relationships it is a well-researched topic however, most existing studies on the topic are quantitative in nature focusing on testing specific theories or principles. Consequently a qualitative study focusing on the experience of initial romantic attraction would add great value in terms of facilitating a better understanding the phenomenon. Furthermore, no qualitative studies pertaining to initial romantic attraction have been done using South African participants. Initial romantic attraction starts with an awareness of a potential partner. Previous studies have indicated that there are many different factors that influence who an individual may be attracted to once awareness of a partner has been established. The current study hopes to identify the factors leading to initial romantic attraction for white heterosexual South African men. Three white heterosexual South African men were sourced as participants. Openended interviews were conducted with each participant. The interviews were then transcribed verbatim and analysed according to specific descriptive phenomenological steps. The analyses yielded central themes pertaining to initial romantic attraction that could be organised into three broad categories namely, personal characteristics, interpersonal characteristics and external factors. Common personal characteristics leading to initial romantic attraction were physical attractiveness, hair, eyes, petiteness, slim physique, cleanliness and teeth. Common personality traits leading to initial romantic attraction were sense of humour, confidence/independence, mysteriousness, intelligence and good conversation skills and common interpersonal characteristics were reciprocal attraction, similarities, contrasting qualities and eye contact. The only common external factor that led to initial romantic attraction was novelty.It is hoped that the results of the current study will lead to a richer understanding of the factors that lead to initial romantic attraction for white heterosexual South African men.

The aim of the dissertation is to create a meeting place between the rural immigrant and the city. It is a system that recognizes the various layers in which the horizontal human meets the vertical city. The meeting place must act as a transition facility where one enters the complex mechanics of city life. It is a celebration of what city life is and can be. The function of the meeting place is to educate and orientate the user in the language and mechanics of city life. It is an archetype of the new life ahead. The catalyst of the meeting place takes the form of a market situated in between Bloed Street Taxi Station and Belle Ombre Train and Taxi Station in the north of Pretoria Central Business District. / Dissertation (MArch(Prof))--University of Pretoria, 2008. / Architecture / unrestricted

This paper digs deeper into the concept of attraction and what makes a marketing agency attractive. The authors focus on the very first stage of a business relationship before the project sets off, seeking to uncover what attraction is and which factors influence it. Through 6 semi structured interviews with companies which has been in a business relationship with marketing agencies the authors investigates what attracted them to that particular agency. As new information appeared in the interviews, the theoretical framework has been extended with more material. At the end of the paper the authors present a model which describes the components of attraction. The model is then discussed and explained.

Sexual selection shaped psychological mechanisms in both sexes to assess potential mates for evidence of mate quality (Buss, 2005). Attraction preferences are one such mechanism (Sugiyama, 2005) and physical attraction preferences are sensitive to fitness-promoting traits present in a potential mate. Physically attractive traits are thought to act as signals of good genetic quality (Neff & Pitcher, 2005) and are preferred because of the advantage such quality bestows towards reproductive success. Specifically, genetic quality is proposed to be a biological requirement necessary for physically attractive traits to develop and be maintained (Johnstone & Grafen, 1993). Furthermore, genetic quality is heritable to offspring, thereby increasing offspring reproductive success (Orr, 2009). All mating decisions inherently involve trade-offs due to costs inflicted on time and resources when choosing a long-term mate. Assessing a mate for genetic quality is imperative to ensuring one selects a quality mate with heritable fitness benefits towards offspring reproductive success (Buss, 2005). In order to minimize costs and maximize benefits when making mate selection decisions, humans use multiple and redundant signals of mate quality (Fink & Penton-Voak, 2002; Møller & Pomiankowski, 1993). Accordingly, this study supposed that siblings act as redundant signals of genetic quality that would factor into mating decisions. Because genetic quality is heritable (Houle, 1991) and visible through physical attractiveness (Thornhill & Gangestad, 1999), this study explored the possibility that knowledge of relatedness influenced attractiveness judgments of human faces. Supporting the main hypothesis of the current study, siblings affected judgments of physical attractiveness for target faces. Analyses showed this effect to be driven entirely by female raters for both male [t(62)=3.87, p<.001] and female [t(61)=2.24, p=.029] target faces. Secondary analyses examining the effects of sibling pair attractiveness differences (low vs. high) showed that relatedness significantly increased female ratings of facial attractiveness for both low and high facially attractive male and low facially attractive female target faces. Results offer two possible conclusions as to the role relatedness may serve in mate quality assessments that align with parental investment as well as kin selection assumptions.
