The major focus of this study is to identify the potentials and obstacles involved in establishing a permaculture in an existing suburban community in Muncie, Indiana.Permaculture is, briefly, a design concept of human settlements which strives to bring about an attitude of ecology and humanity in society as a whole. The physical of the earth by involving design stresses energy conservation and production of renewable natural resources, ecological food production techniques, and the recovery of a genuine sense of community and a sense of the sacredness of the earth by involving people with people and people with the landscape.The First Presbyterian Church site and congregation in Muncie has been chosen for this study. A permaculture proposal has been developed for and presented to the community. Initial reactions to this proposal have been obtained in order to identify the potentials and obstaclespresent toward implementing the permaculture proposal in this unique suburban setting. / Department of Landscape Architecture

There is an increasing awareness that human beings are disconnected from nature. Physical disconnectedness from nature may lead to psychological and spiritual malfunctioning. Those who are aware of this disconnectedness try to compensate by spending leisure time in nature. The urge to go 'back to nature' was the start of ecotourism. The increase in tourist traffic and the concomitant development brings about negative effects, subjecting tourists to disappointment. Development has destroyed the specific experience which the people came for in the first place. Should environmental degradation continue the enriching experiences people have in nature will no longer exist. The preferred outcome for eco tourists is to acquire a sense of spiritual sustenance that could enhance their optimal functioning after experimenting a natural environment. A disregard for sound principles of responsible ecotourism development could result in lost opportunities. The research problem is located in the fact that individuals are seldom aware of their disconnectedness from the natural environment. Secondly, there is a need for more pristine, natural environments where humans can restore their encounters with the nature. Ecotourism development should be sensitive to the tastes of tourists who have as their objectives memorable experiences in natural environments. During this exploratory study, interviews, questionnaires and field observations were used to collect qualitative and limited quantitative data. Findings confirm that human beings are part of nature. Technological progress has led to an indoor lifestyle that causes humans to become disconnected from nature. Disconnectedness also involves a spiritual dimension. To restore a sense of connectedness between human beings and nature, people need to spend time in nature. Ecotourism originated from and exists because of the desire of individuals to reconnect to nature. They fulfil this desire by experiencing unspoilt natural environments, both physically and spiritually. Although a pattern of phases in a nature experience can be distinguished, every individual attaches a personal meaning to the experience. People have satisfying nature experiences in any natural environment. The intensity or fulfilment of such experiences depends on personal perceptions as well as external disturbances, such as litter and inappropriate behaviour. People attach meaning to experiences by structuring them into stories. The more we talk about the nature experience, the more knowledge is added to it. Consequently the experience becomes powerful, adding quality to people's lives and relationships. In this regard, aspects of rituals, metaphors and symbols, as well as spiritual experiences, play a significant role in the meaning people find in natural environments. / Thesis (Ph.D. (History))--North-West University, Vaal Triangle Campus, 2005

Palestine has one of the longest histories of archaeological exploration in the Near East "because the recovery of its material remains has "been of great value in interpreting biblical literature, which in turn has shed much light on the ancient history of the Levant in general. In order to establish the chronological setting, Sir Flinders Petrie was the first Near Eastern archaeologist to devise a system of sequence dating based upon the scientific study of pottery in its stratigraphical position within a mound. As a result of his researches in Palestine, the first systematic attempt was made to record a corpus of pottery representing all periods of occupation during which pottery occurred. The result was the publication by Duncan of the Corpus of Palestinian Pottery (London, 1930). Since 1930, the study of pottery types has been greatly refined and enlarged so that at least the general periods of Palestine's history can now be defined in some detail by known pottery types. The best modern compilation of the pottery from its beginnings in the Neolithic period to the end of the Iron Age is Amiran's Ancient Pottery of the Holy Land (Jerusalem, 1969). Many special studies of pottery, the latest being Franken's In Search of the Jericho Potters (Leiden, 1975), employ both old and new methods of typology in ceramic studies in an effort to understand more completely the cultural and chronological changes within the various periods of Palestinian history ...

In this master thesis the reasons, tendencies and outcomes of the labour migration in Lithuania have been analysed. According the data of different researches carried out in Lithuania, almost 90% of people depart abroad due to financial reasons. This research may contribute to revealing the deep reasons and motives of labour migration, and its founding might be used dealing with the problem how to recapture the emigrants to Lithuania, and how to suppress a flow of emigrants from our country.

Transposable elements (TEs) are mobile DNA sequences that can move from one location to another in the genome. These elements encode regulatory features including transcriptional promotion and termination signals facilitating the production of new transcripts (or elements). The elements thus produced are inserted back into the genome. Due to their insertional capacity and encoded regulatory features, TEs have, in recent years, been recognized as significant contributors to regulatory variation both within and between species. In comparing the human and chimpanzee genomes it has been hypothesized that the genetic basis of the phenotypic differences that distinguish them may be the result of regulatory differences existing between the two species. Since TEs inserted in proximity to genes can significantly alter gene expression patterns, this research aims at exploring the influence of TE sequences and retrotransposons in particular in the evolution of gene regulation between humans and chimpanzees. A first systematic search of one particular class of retrotransposons - endogenous retroviruses (ERVs) was carried out in the chimpanzee genome. Forty two families of ERVs were identified in the chimpanzee genome including the discovery of 9 previously unknown families in humans. The vast majority of these families were found to have orthologs in the human genome except for two (CERV 1/PTERV1 and CERV 2) families. The two CERV families without orthologs in the human genome display a patchy distribution among primates. Nine families of chimpanzee ERVs have been transpositionally active since the human-chimpanzee divergence, while only two families have been active in the human lineage. The genomic differences [INDEL variation (80-12,000 bp in length)] between humans and chimpanzees are laid out. The INDEL variation located in or near genes is categorized in detail and is correlated with differences in gene expression patterns in a variety of organs and tissues. Results indicate that the majority of the INDEL variation between the two species is associated with retrotransposon sequences and that this variation is significantly correlated with differences in gene expression most notably in brain and testes. These findings are consistent with the hypothesis that retrotransposon mediated regulatory variation may have been a significant factor in human/chimpanzee evolution.

It is widely believed that Australian Aboriginals utilised fire to manage various landscapes however to what extent this impacted on Australia???s ecosystems remains uncertain. The late Pleistocene/Holocene fire history from three sites within the Sydney Basin, Gooches Swamp, Lake Baraba and Kings Waterhole, were compared with archaeological and palaeoclimatic data using a novel method of quantifying macroscopic charcoal, which is presented in this study. The palynology and other palaeoecological proxies were also investigated at the three sites. The Gooches Swamp fire record appeared to be most influenced by climate and there was an abrupt increase in fire activity from the mid-Holocene perhaps associated with the onset of modern El Ni??o dominated conditions. The Kings Waterhole site also displayed an abrupt increase in charcoal at this time however there was a marked decrease in charcoal from ~3 ka. Lake Baraba similarly had displayed low levels of charcoal in the late Holocene. At both Kings Waterhole and Lake Baraba archaeological evidence suggests intensified human activity in the late Holocene during this period of lower and less variable charcoal. It is hence likely that at these sites Aboriginal people controlled fire activity in the late Holocene perhaps in response to the increased risk of large intense fires under an ENSO-dominated climate. The fire history of the Sydney Basin varies temporally and spatially and therefore it is not possible to make generalisations about pre-historic fire regimes. It is also not possible to use ideas about Aboriginal fire regimes or pre-historic activity as a management objective. The study demonstrates that increased fire activity is related to climatic variation and this is likely to be of significance under various enhanced Greenhouse scenarios. There were no major changes in the composition of the flora at all sites throughout late Pleistocene/Holocene although there were some changes in the relative abundance of different taxa. It is suggested that the Sydney Sandstone flora, which surrounds the sites, is relatively resistant to environmental changes. Casuarinaceae was present at Lake Baraba during the Last Glacial Maximum and therefore the site may have acted as a potential refugium for more mesic communities. There was a notable decline in Casuarinaceae during the Holocene at Lake Baraba and Kings Waterhole, a trend that has been found at a number of sites from southeastern Australia.
