Reorganization and Risk: Environmental Change and Tribal Land Use in Marginal Landscapes of Southern Jordan
No full textabstract: This research on the early metal ages of the Wadi el-Hasa focuses on the
settlement systems and attempts to explain how social, economic and political
adjustments helped tribal groups survive under natural (i.e., climatic) and anthropogenic
(i.e., land degradation, erosion) stress factors. The shifting of subsistence base from
agropastoral to pastoral their reflections in site and population densities, diversity of site
types, levels of internal complexity and levels of social organization via the presence of
large settlements, like villages, which acted as economic and administrative centers
emerge as risk reduction mechanisms. The cycles of abandonment and resettlement are
evaluated within the concept of social reorganization and such changes are assessed as
parts of economic revitalization attempts. The social changes that emerge from such
shifts are evaluated from the perspective of the scale-free networks model and tested
through statistical methods, such as ANOVA, for spatial and temporal patterns while
patterns of land use and the impacts of changing climate and anthropogenic activities are
evaluated with GIS. Following the dimorphic society and heterarchic social organization
concepts, the discussion emphasizes that tribal groups adjust population density, range
and intensity of activities in marginal landscapes, like the Hasa, in order to prevent
environmental degradation. These patterns may change once these marginal landscapes
are integrated to more complex social organizations. Although this takes place in the
Hasa during the Iron Age, the research results imply that environmental degradation did
not take place possibly due to the continuation of extensive subsistence patterns, along
with the emergence of the long-distance caravan trade as a major economic incentive

Spatial dependence-based fuzzy regression clustering
No full textFuzzy clustering based regression analysis is a novel hybrid approach to capture the linear structure while considering the classification structure of the measurement. Using the concept that weights provided via the fuzzy degree of clustering, some regression models have been proposed in literature. In these models, membership values derived from clustering or some weights obtained from geometrical functions are employed as the weights of regression system. This paper addresses a weighted fuzzy regression analysis based on spatial dependence measure of the memberships. By the methodology presented in this paper, the relative weights are used in fuzzy regression models instead of direct membership values or their geometrical transforms. The experimental studies indicate that the spatial dependence based analyses yield more reliable results to show the correlation of the independent variables into the dependent variable. In addition, it has been observed that spatial dependence based models have high estimation and generalization capacities. (C) 2011 Elsevier B.V.

Eco-Urban Futures: A More-than-human Approach to Multi-Agent Simulation for the Digital Twin of Urban Forests
No full textUrban forests are now digitalized as smart green infrastructures to mitigate environmental change. Cities are proactively planting and replacing trees considering their future ecosystem benefits, such as carbon sequestration, urban heat reduction, and water retention. Digital twin simulation is a key technology enabling this particular mode of governance, which generates future scenarios under various management schemes. These data inform decisions on tree selection and placement, thereby shaping forests into uniquely efficient and responsive urban organisms. Despite its positive prospects, however, the underlying ontologies of these digital forests are rarely questioned, often lacking consideration for the flora and fauna inhabiting the forests. The models built upon anthropocentric biases and values pose a risk of selectively consolidating futures where the forests are optimized only for humans, which does not always guarantee the same good future for multi-species.Acknowledging that humans coexist with other forms of life, Eco-Urban Futures takes a more-than-human approach in designing the computational model and a simulation platform. The notion of more-than-human bodies was constructed as a strong concept to explore alternative modes of making sense of and acting upon data toward more-than-human forest governance. The designed interface enables users to navigate the forest data across diverse temporal, spatial, and agential scales, thereby urging policymakers, urban planners, and citizens to reimagine healthier futures for us-with-the-forest.Design for Interactio

Individual cognitive structures and collaboration patterns in academia
No full text13th International Conference on Scientometrics and Informetrics -- JUL 04-07, 2011 -- Univ Zululand, Durban, SOUTH AFRICAThis article, elaborating on mutuality of knowledge and social structure theory borrowed from sociology of knowledge literature, where knowledge is perceived as an essentially social and societal category, develops a coherent research framework which relates cognitive structure and the collaboration patterns into an integrated socio-knowledge analysis of a given scientific community. The framework extends co-word analysis combining it with social network analysis. The framework is enhanced by introducing a novel model. The new model maps actors from co-authorship networks into a strategic diagram of scientists. The mapping is based on cohesiveness and pervasiveness of issues each author has published in the field. The exemplary longitudinal case from Turkey covers scientific publication activities in Turkish management academia spanning the years from 1922 until 2008. It is seen that, while within local community diffusion of management knowledge is lead by academicians with certain socio-cognitive properties, academicians publishing at international arena do not show any significantly differing socio-cognitive properties, instead, they are merely embedded in strongly connected groups. Leading academicians within local community, however, exhibit a common socio-cognitive structure relative to the rest of the community. They have more social ties and more diversified disseminated knowledge compared to the rest. Knowledge they disseminate is distinct compared to their peers in the network, they hold certain part of their knowledge exclusively, thus knowledge-wise they don't resemble the rest, but they keep a level of common knowledge with the rest of the community.Int Soc Scientometr & Informetr (ISSI),Durban Univ Techno
Electric field analysis of 66 kV and 110 kV SiR insulators under combined AC-DC voltages
No full textInsulators are the most crucial part of power systems. The insulation performance of insulators is vital for the sustainability of power systems. Recently, silicone rubber (SiR) insulators are used frequently in all sections of the power systems. In this paper, a SiR insulator currently used in power transmission systems has been analyzed under combined AC-DC voltage using the finite element method. In the analysis, positive and negative DC voltages in different amplitude ratios were superimposed over the phase-earth operating voltage of the insulator. Analyses in the study were made in time-dependent. Only DC voltage was applied to the insulator for the first 60 s, AC + DC voltage was applied between 60 to 120 s. Thus, the electric field behavior of the SiR insulator under combined AC-DC voltage has been obtained. The change of electric field based on positive and negative DC components was investigated. As a result of the study, the effect of the polarity of the DC component in the combined voltage was observed. As a result, effect of the polarity of the DC component in the combined voltage on the maximum electric field intensity was observed. (C) 2021 The Author(s). Published by Elsevier Ltd
Turbulent drag reduction through spanwise wall oscillation: An experimental investigation by Tomographic PIV
No full textTurbulent boundary layers are responsible for up to 89 % of the skin friction drag of civil aircraft. This shows that in regard to the current social sensitivity towards climate friendly aviation a reduction of tur- bulent skin friction could have a large impact. On the one side greenhouse gas emissions by aviation could be reduced and on the other hand fuel costs could be saved, an important consideration for air- lines. The research on turbulent drag reduction distinguishes between passive and active techniques. Passive techniques have the advantage that no energy input is necessary. Prominent examples are riblets and dimples which have shown turbulent drag reductions up to 10 %. Active techniques reach turbulent drag reduction percentages of up to 45 %, however it is in doubt if the energy savings are larger than the energy required to operate the control technique. One promising active technique which has proven to partially generate a positive energy effect is spanwise wall oscillation. However, researchers have opposing opinions of the mechanism which leads to the drag reduction. As turbulent boundary layers are strongly three-dimensional, the work of this thesis investigates three-dimensional flow fields of turbulent boundary layers subjected to spanwise wall oscillation by means of tomographic PIV. These are used to study the changes in pointwise statistics and coherent structures in order to derive a descriptive model of the drag reducing mechanism.Aerospace Engineerin
