Μελέτη των αναδασώσεων στο δάσος της Στροφιλιάς ΒΔ Πελ/σουΦωτόπουλος, Αθανάσιος 26 October 2007 (has links)
Η εργασία αυτή αποτελεί μελέτη του δάσους της Στροφιλιάς (Αχαϊας) με σκοπό την εξαγωγή συμπερασμάτων για τη δυνατότητα, τους τρόπους και τη χρησιμότητα της τεχνητής αναδάσωσης. Επίσης, διερευνώνται οι αλλαγές που είναι πιθανόν να προκαλέσει μια εκτεταμένη αναδάσωση στο οικοσύστημα. Παράλληλα θα αναφερθούν οι παράγοντες που υποβαθμίζουν το οικοσύστημα, οι κίνδυνοι που αντιμετωπίζει και με πιο τρόπο οι αναδασώσεις μπορούν να ωφελήσουν την περιοχή, αλλά και οι πιθανές δυσμενείς επιπτώσεις από λανθασμένες αναδασωτικές πρακτικές. Για το λόγο αυτό γίνεται αναφορά τόσο στις θεωρητικές αρχές που διέπουν τις αναδασώσεις όσο και στον τεχνικό τρόπο που αυτές οι αρχές θα εφαρμοστούν στην πράξη, προσαρμοζόμενες στις ιδιαιτερότητες της περιοχής. / This work constitutes study of forest of [Strofilias] of (Achaia) aiming at the export of conclusions on the possibility, the ways and the usefulness of artificial reforestation. Also, are investigated the changes that it is likely to cause a extensive reforestation in the ecosystem. At the same time will be reported the factors that downgrade the ecosystem, the dangers that faces also with more way the reforestations can profit the region, but also the likely unfavourable repercussions from erroneous [anadasotikes] practices. For this reason it is mentioned the theoretical aspects that condition the reforestations andin the technical way that these conditions will be applied into practice, adapted in the particularities of region.

Long-term changes in the organization of lithic technology : a case study from the Imjin-Hantan River Area, KoreaYoo, Yongwook, 1969- January 2007 (has links)
This study is intended to furnish an explicability of hunter-gather's organizational model on the lithic technology. The fieldwork area is the Imjin-Hantan River Area (the IHRA) located at the midwestern part of the Korean Peninsula. The archaeological sites included in the fieldwork are Jangsanri (ca 0.2 Mya BP), Chongokni (ca 60 Kya BP), Juwolri, and Kawolri (younger than ca 50 Kya BP). In addition, a previously excavated Upper Palaeolithic assemblage of Janghungri (ca 23 Kya BP) is included in the quantitative analysis of lithic assemblages. / For the background of the research area, chapter II is devoted to demonstrating the general environment of East Asia and current Quaternary research of Korea. Chapter III furnishes the basic knowledge on the geomorphological environment of the IHRA and the research history in this area for the last three decades was elaborated. / Chapter IV is a description on the excavation fieldworks, introduction of the discovered lithic artifacts, and new age determination based on the K-Ar, IRSL, OSL, and AMS dating methods. Chapter V is the general characteristics on the IHRA lithic assemblage. Some descriptive details on the individual artifacts are presented and technological implications of lithic types are delineated. In addition, a general reduction sequence of the IHRA assemblage is proposed. / Chapter VI is a quantitative analysis based on the exploratory data analysis (EDA); some geometric variables of artifacts were operationally defined for the purpose of acquiring more implicative analytical units. As a result of the analysis, it is revealed that the distinct interassemblage variability of raw material composition and of the morphological features of small tools and blanks constrained by differential reduction intensity can be explained in the context of the long-term-based strategic changes executed by the IHRA hominins. / Chapter VII, based on the results from the fieldwork and lithic analysis, attempted to reconstruct the geological history of the IHRA in terms of hominid's land use patterns and relevant survival strategies. As a final remark, some unsolved issues were diagnosed and future research was expected for the continual research of the IHRA.

Diagnostic flake analysis : a replication-based method for reconstructing reduction techniques, strategies, and technologiesMoore, Mark W. January 1990 (has links)
Diagnostic flake analysis is based on the concept that distinct flintknapping techniques produce distinctive flakes. Seen in this light, the information potential of flakes is enormous. Unfortunately, this information is virtually lost in analyses based upon size-grading a flake assemblage or separating flakes statistically based on a few "key" attributes. The intent of this study is to provide and apply a well-integrated analytical approach based upon the diagnostic flake concept.In order to integrate the static lithic artifacts to the dynamic behavior that produced them, a generalized flow chart model of the knapping event is developed. The flow chart model emphasizes the debitage produced during knapping, rather than finished lithic tools. The flow chart model is described in detail, and the terms"technology", "strategy", and "techniques" are defined and contrasted.A total of 30 reduction experiments were conducted in the course of this study, producing an estimated 27,000 flakes and flake fragments. Based on this sample and previous work conducted by Flenniken (n. d. ) and others, nine diagnostic flake types and three significant flake attributes are defined.An ideal methodology for a lithic analysis is developed. This ideal methodology includes: 1) assessing the types of raw materials present on a site; 2) reconstructing the technology based on negative-flake scars on finished tools; 3) flake refitting; 4) classifying flakes into the diagnostic flake categories nonstatistically and polythetically, with special emphasis placed on recognizing previously unidentified diagnostic flake types; 5) developing a flow chart model of reconstructed prehistoric technology; and 6) summarizing the flow chart i n verbal form.The methodology is applied to the Middle and Late Woodland components of the stratified All Seasons site located in central Indiana. Analysis of the Middle Woodland assemblage results in the recognition and definition of conical core flake blanks.The methodology is applied to a blind test manufactured by Donald Cochran to assess bias that may have been introduced into the flake type definitions by using debitage produced only by the author. Cochran's behavior is accurately reconstructed.Finally, the results of the study are discussed, and the study's strengths and weaknesses are determined. Diagnostic flake analysis is found to be a powerful approach that derives an optimal amount of high-quality information from a chipped stone assemblage. / Department of Anthropology

Aspects of lithic assemblage variability in the late Palaeolithic of south-east ItalyMilliken, Sarah January 1991 (has links)
This thesis concerns late Palaeolithic settlement in the region of Puglia, south-east Italy, at the close of the Pleistocene. Puglia comprises three sub-regions which contain sites of this period: the Salento peninsula, the Murge, and the Gargano promontory. The late Palaeolithic occupation must be considered in relation to the former existence of an extensive coastal plain, and to the sea-level rise which submerged it. The late Palaeolithic assemblages of the region have been studied previously by Italian archaeologists from a rigid typological stance, with various schemes put forward suggesting evolution of the assemblages through different stages of an Epigravettian tradition. In this thesis, attribute analysis is used to re-examine the principal assemblages, using published data where adequate and supplemented by samples studied by the author in Italy. The results are analyzed to seek the social and economic factors which shaped the various industries, as well as diachronic change wherever it can be demonstrated. Factors such as difficulty in obtaining raw material were clearly crucial to assemblage composition. The existing typological schemes are shown to lack real bases and to mask rather than reveal sociocultural information. Chapter 1 states the aims of the thesis and critically discusses previous theoretical approaches to the late Palaeolithic of the region. Chapters 2 and 3 describe relevant aspects of the regional palaeoenvironment. The author's own methodological approach is explained in Chapter 4, and then used for a detailed study of the assemblages from Grotta delle Cipolliane in Chapter 5. This is followed in Chapter 6 by a broader study of the late Palaeolithic assemblages in Puglia, with discussions of their possible diachronic and synchronic relationships. Chapter 7 develops this latter theme into an attempt to understand the social and economic features of the late Palaeolithic settlement of Puglia, and suggestions are made concerning future work that might improve the quality of the archaeological evidence. Chapter 8 summarizes the main conclusions of the thesis.

Landscape and technology in the Peak District of Derbyshire : the fifth and fourth millennia B.CHind, Daniel January 2000 (has links)
This thesis is concerned with two closely related themes: the inhabitation of the Peak District over the fifth and fourth millennia BC, and the procedures and principles by which we attempt to interpret the durable material traces thereof. A four stage interpretative framework is outlined. Social life is understood through its materiality. The engagement of the self with others is constrained and enabled by that materiality. Archaeologists can represent that process through a textual model. Analogical reasoning mediates each stage and must be made explicit. The Mesolithic and Neolithic, analytical objects constructed through conceptual metaphors, fail to express time and the materiality of practice as mutually constitutive. An integrated theory of landscape and technology is proposed whereby artefacts are understood in terms of relational metaphors, situating them in practice and capturing both their materiality and temporality. Prior research in the study area is critiqued on the basis that the historically specific material conditions therein cannot support models transposed from other regional contexts. A methodology for collection and analysis is developed which privileges those specific conditions in the interpretation of prehistoric technology. Artefact assemblages, it is argued, offer us no unmediated access to prehistoric settlement. No immediate functional equivalence between aggregations similar in composition should be expected. The analysis of stone tools and waste must be integrated with other categories of evidence and interpreted in terms of the potentials offered by their socio-physical context. Original data are analysed in terms of assemblage density, raw material and technological composition, chronological patterning and landscape situation. Integration into the regional corpus, through an explicitly multi-scalar approach, attends to the constitution of social life through practice and developing tradition. The role ascribed to early `monuments' by other archaeologists is particularly brought into question, with respect to the model of relational practice maintained throughout the dissertation.

Stone tool production at Cat's Eye Point, Kakanui, North Otago, New ZealandWilson, Amanda J, n/a January 1999 (has links)
This thesis examines a lithic assemblage from Cat�s Eye Point (J42/4), Kakanui, North Otago, New Zealand. This archaic site was excavated during 1996 and 1997 and the lithic assemblage was collected from 41m� excavated during these two seasons. Previous studies of lithic material from New Zealand and the Pacific are reviewed to indicate the range of information that can be gained from lithic analysis. Themes of research in the North Otago region are also examined to place Cat�s Eye Point into its regional context.
This thesis had three main areas of investigation. The first involved a descriptive and technological analysis of the debitage using mass flake analysis (MFA) and individual flake analysis (IFA). Formal artefacts, such as hammerstones, blanks, and performs, were also examined. Secondly, spatial analysis was used to determine if the lithic assemblage could be used to infer intra-site activity areas. This was conducted by analysing macro- (flakes larger than 3mm) and microdebitage (flakes less than 3mm) by examining the range of material types. The third area of investigation examined debitage recovered from 6.4mm (1/4 inch) and 3.2mm (1/8 inch) sieves to determine if any significant technological information was gained by debitage from the 3.2mm sieve.
The conclusions of this study indicate that there were two methods of basalt cobble reduction at Cat�s Eye Point for adze production. Adze production at Cat�s Eye Point was opportunistic and the non-local material curated. The results of the debitage analysis indicate that the entire sequence of adze manufacture did not occur in the excavated area of Cat�s Eye Point and the initial cobble reduction probably occurred on the adjacent beach where the cobbles are found today. Consequently, coastal rock outcrops, even without evidence of associated debitage, must be viewed as potential sources of rock for stone tool manufacture unless determined otherwise. The spatial analysis detected two activity areas and a disposal area at Cat�s Eye Point. The analysis of the 6.4mm and 3.2mm debitage found that no significant technological information was gained by examining the smaller flakes.
