Understanding Community: A Comparison of Three Late Neolithic Pottery Assemblages from Wadi Ziqlab, Jordan

Gibbs, Kevin Timothy 19 January 2009 (has links)
This study presents the results of an analysis of three Late Neolithic pottery assemblages from Wadi Ziqlab, northern Jordan. These sites were occupied during the 6th millennium BC (calibrated) and are therefore contemporary with sites in other parts of the southern Levant that are attributed to the Wadi Rabah culture. The assemblages are analyzed from a stylistic perspective, broadly defined, which includes an examination of technological style in addition to a more traditional examination of vessel form and surface treatment. Different stages in the pottery production sequence are investigated using a range of analytical techniques, including thin-section petrography and xeroradiography. While there are some similarities between the assemblages, there are also some noticeable differences. The results of the pottery analysis are used to explore the nature of community in the context of the Late Neolithic. A critique of more traditional archaeological approaches to prehistoric communities leads to a re-conceptualization of community that combines interactional and ideational perspectives. Similarities in pottery among the sites, especially technological similarities, suggest that pottery producers may have comprised a dispersed community of practice. At the same time, pottery may have also been a symbolic marker of community boundaries. Differences in pottery among the sites, including surface treatment, may reflect the flexibility of these boundaries as different parts of the dispersed community negotiated their place in it. The presence of variation among contemporary pottery assemblages in a localized area suggests that social organization during the 6th millennium may have been more complex than is normally assumed for the Late Neolithic in the southern Levant. A dispersed community, with its members spread throughout the wadi, would require a sufficiently complex and flexible system of relationships to maintain it. Failing to acknowledge this has contributed to the difficulties archaeologists have encountered when trying to understand the culture-history of the 6th millennium BC in and east of the Jordan Valley.

STRATIGRAPHIC REEVALUATION OF MOLLIES NIPPLE, KANE COUNTY, UTAH, USA TO BETTER UNDERSTAND THE ORIGIN OF ALUNITE AND JAROSITE CEMENTS

Walker, Jordan Thomas 01 August 2022 (has links)
Mollies Nipple is a butte located in Kane County, Utah and is part of Grand Staircase-Escalante National Monument (GSENM). Mollies Nipple is now of particular interest to the Mars research community because of the presence of unusual diagenetic alunite and jarosite minerals. These minerals are present in sedimentary environments on Mars and have been used to interpret the diagenetic and depositional environments as acidic and/or arid. On Earth, these minerals are present in modern acid saline lakes, fumaroles, or acid mine drainage, but not commonly as diagenetic cements. The butte was mapped as Navajo Sandstone via photogeologic mapping, but the apex is 200 m higher than the surrounding upper extent of that unit in adjacent areas and there are some lithological inconsistencies that suggest the caprock may be a different overlying formation. Correctly understanding the diagenetic and depositional history of Mollies Nipple will inform future studies on Mars and has the potential to change the paradigm of these interpreted jarosite-bearing Martian environments. Stratigraphic sections were measured in the field and samples were collected for laboratory analysis. The dominant lithofacies is a cross-bedded quartz arenite. Structureless quartz arenite to wacke with lenticular green-gray quartz wacke (ash) is also present. Jarosite cement is common in upper sections of Mollies Nipple and is present, but sparse, in lower section of Mollies Nipple. Alunite is present in the upper section of Mollies Nipple. ANOVA conducted on point count data from samples collected from Nipple and representative samples of potential formations at Mollies Nipple do not differentiate between the possible formation candidate and Navajo Sandstone. Based on distribution of lithofacies, comparison with adjacent outcrops of Temple Cap Formation, Page Sandstone, and Carmel Formation, we conclude that the caprock at Mollies Nipple is most likely the Temple Cap Formation.

Rainfall Data Analysis and Rainfall – Runoff Modeling: Rainfall – Runoff Modelling for the upper Catchment area of Wadi Ma’awil (Gauge near to Afi’) in the Sultanate of Oman

Abraha, Zerisenay Tesfay, Hossain, Sazzad 04 March 2021 (has links)
Within the frame work of the International Water Research Alliance Saxony (IWAS), project “Middle East” a complex integrated water management system is developed and tested in the project region of Middle East (Oman and Saudi-Arabia). Hence, new solutions for a sustainable management of the scarce water resources in (semi-) arid regions are explored within IWAS in the sultanate of Oman on which this study work is carried out. Rainfall runoff models are established to estimate the “water yield” of the catchments in the project region. Modeling is a very important tool that enables hydrologists to make more comprehensive use of rainfall time series. Rainfall-runoff modeling is also useful for water resources assessment as these models can generate a long representative time series of stream flow volumes from which water supply schemes can be designed (D.A. Hughes, 1995). Therefore, this study project mainly focuses on the following main tasks such as data analysis, data processing and statistical evaluation; Model selection and model setup; Model adaptation test and verification. As part of the common modeling protocol, sensitivity analysis of a Rainfall-Runoff Modeling Toolbox (RRMT) is carried out in this study with the aim to identify sensitive model parameters. RRMT has been developed in order to produce parsimonious, lumped model structures with a high level of parameter identifiability. Such identifiability is crucial if relationships between the model parameters representing the system and catchment characteristics are to be established. RRMT is a modular framework that allows its user to implement different model structures to find a suitable balance between model performance and parameter identifiability. The study is carried out in the upper catchment part of Wadi Ma’wil (gauge near to Afi’), Batinah Region of the Sultanate of Oman. Arid and semi-arid zones are characterized by rainfall which is highly variable in space, time, quantity and duration (Noy-Meir, 1973). The Sultanate of Oman is characterized by hyper-arid (<100 mm rainfall), through the arid (100–250 mm rainfall) and semi-arid (250–500 mm rainfall) environments that are experienced in different parts of the country. Furthermore, arid areas have distinctive hydrological features substantially different from those of humid areas. The high temporal and spatial distribution of the rainfall, flash floods, absence of base flow, sparsity of plant cover, high transmission losses, high amounts of evaporation and evapotranspiration and the general climatologies are examples of such differences.:Acknowledgments i Abstract ii List of Figures and Photos v List of Tables and Plots v 1.

Riwaya Teule za Karne ya Ishirini na Moja na Udurusu wa Nadharia za Fasihi

Mwamzandi, Issa 27 March 2014 (has links) (PDF)
Literary theory represents a way of thinking and a body of writing that is dedicated to the analysis of literary texts. It is a means through which literary critics come to appreciate the nature of the literary texts they seek to analyze and the methodology that informs their practice. Analyzing three 21st Century Swahili novels, this paper examines a paradigm shift: literary theory becomes the sub¬ject under examination as opposed to its conventional role where it would ideally offer systematic views of what such texts would mean. Said Ahmed Mohamed’s Dunia Yao (2006) and Nyuso za Mwanamke (2010) on the one hand, and Kyallo Wadi Wamitila’s Musaleo! (2004), on the other, represent a new kind of writing that experiments on literary theory as a subject for criticism. In these texts, we read about the tenets and practice of a variety of literary theories including Russian formalism, Saussurean and Jakobsonian structuralism, Derrida’s deconstruction, Edward Said’s post-colonial theory, and Carl Gustav Jung’s psychoanalytical theory. While this experiment that the two novelists engage in may appear elitist for the average reader at first, the paper contends that this form of writing will in the long term assist in the domestication of literary theory. Further, the three texts could greatly assist in pedagogical issues if read alongside other mandatory course books on literary theory.
