Socioeconophysics: Opinion Dynamics for number of transactions and price, a trader based model

Involving effects of media, opinion leader and other agents on the opinion of individuals of market society, a trader based model is developed and utilized to simulate price via supply and demand. Pronounced effects are considered with several weights and some personal differences between traders are taken into account. Resulting time series and probabilty distribution function involving a power law for price come out similar to the real ones.Comment: will be published in IJMPC 17 (2006

Physics of randomness and regularities for cities, languages, and their lifetimes and family trees

Time evolution of the cities and of the languages is considered in terms of multiplicative noise and fragmentation processes; where power law (Pareto-Zipf law) and slightly asymmetric log-normal (Gauss) distribution result for the size distribution of the cities and for that of the languages, respectively. The cities and the languages are treated differently (and as connected; for example, the languages split in terms of splitting the cities, etc.) and thus two distributions are obtained in the same computation at the same time. Evolutions of lifetimes and families for the cities and the languages are also studied. We suggest that the regularities may be evolving out of randomness, in terms of the relevant processes.Comment: 22 pages including all figures; for Int. J. Mod. Phys. C 18 (2007

Mass Housing and Changings in Housing Demand, Case of Diyarbakir, Turkey

The aim of this study is to analyze changings in housing demand, especially in term of house size in Diyarbakýr case, in Turkey. Though Housing in Turkey is in a free market system, there is a Mass Housing Administration (TOKÝ) has been doing mass houses for, relatively, middle class income people. Diyarbakýr, one of the cities that TOKÝ has done two thousand houses, has taken too much migration, so that the demand in housing form and structure has different alterations. This process should be under control not only for the economy but also for sustainable housing environment and for sustainable urbanism. Immigration from rural areas to cities for better living conditions has started with urbanization and resulted with overpopulation in the cities of Turkey. Mass housing fact is formed in order to satisfy shortage of housing. The quantity as well as the quality of housing has reached seriously to a high degree. There are many slums in Diyarbakýr which has density of wraped urbanization. Since 1994, Mass Houing Management has started new projects to prevent such an unhealthy settlement being consructed and to supply more houses for the homeless Iiving in the town. In this work, inhabitants in different settlements wiil be questioned to identify their economic, social and spatial needs comparing with mass housing. Besides, comparison between the people’s preferences on housing those don’t live never in mass housing and the people’s desire alterations those live in mass housing by investigation of their settlement process will be done. The level of coorelation between the function and house size will be examined for decreasing the housing ownership process and cost. The proposals about sustainable housing environment will be given. Such research is considered to be helpful for future house planing in Turkey’s cities like Diyarbakýr.

The geology and the ore mineralization in the Keban area, east Turkey

The Keban mine is one of the most important lead and zinc producers in Turkey. It is located 54 km NW of Elazig County, Eastern Turkey. The Keban metamorphic massif consists of calc-schists, dolomite marble, phyllite and marble. It forms part of the eastern Taurid belt, a prolongation of the Alpine orogenic belt. The principal structural feature of the area is the northern extension of the Malatya-Keban anticline, a major recumbent fold with a NE-SW axis. Later movements acting in different directions gave rise to N-S, E-W, NW-SE and NE-SW directed folding and faulting over the previous anticline. Small bodies of quartz-syenite porphyry, of paleocene age, intrude the metasediments. Detailed study by chemistry, petrography and x-ray techniques on sanidine accounts for a composition range between Or65 Ab35 and Or99 Ab1. The ratio of Or to Ab tends to increase outwards from the central parts of the igneous body. Skarn zones have developed in association with the intrusion of quartz-syenite porphyry. These are located mainly within the metasediments. The magnatite deposit of Zereyandere, the scheelite deposit of Kebandere and the main sulphide deposit were formed as part of the process of skarn formation. Minor amounts of some manganese minerals and the minerals vanadinite and descloizite derived from the main sulphide deposit, are also found in the district. The main sulphide deposit of economic importance chiefly incudes sphalerite, galena, iron and copper sulphides and several sulfo-salts in subordinate amounts. Of the by-products, silver comes from galena, polybasite and tennantite. Arsenopyrite in addition to chalcopyrite contains trace concentrations of gold. All the evidence suggests that the quartz- syenite porphyry is the source of mineralization. The location of ore minerals is controlled by certain rock types and by major and minor structural elements. Variation of vapour fugacity and temperature during mineralization are indicated by more than one stage of formation for certain ore minerals. The presence of different gangue minerals marks the fluctuating nature of the ore forming fluids whose last stage is believed to be alkaline rather than acidic. The main sulphide deposit is accepted as a semi-metasomatic contact deposit, while the magnetite and scheelite deposits are classified as being metamorphic. Using various methods, a temperature range of formation between 620° and 78°C is estimated for the ore minerals of the main sulphide deposit. For the ore minerals of the magnetite and scheelite deposits the range is from 743°C down to 225°C

Body waves in poroelastic media saturated by two immiscible fluids

A study of body waves in elastic porous media saturated by two immiscible Newtonian fluids is presented. We analytically show the existence of three compressional waves and one rotational wave in an infinite porous medium. The first and second compressional waves are analogous to the fast and slow compressional waves in Biot's theory. The third compressional wave is associated with the pressure difference between the fluid phases and dependent on the slope of capillary pressure-saturation relation. Effect of a second fluid phase on the fast and slow waves is numerically investigated for Massillon sandstone saturated by air and water phases. A peak in the attenuation of the first and second compressional waves is observed at high water saturations. Both the first and second compressional waves exhibit a drop in the phase velocity in the presence of air. The results are compared with the experimental data available in the literature. Although the phase velocity of the first compressional and rotational waves are well predicted by the theory, there is a discrepancy between the experimental and theoretical values of attenuation coefficients. The causes of discrepancy are explained based on experimental observations of other researchers

Exploring the Intersection of Digital Virtual Consumption and Family Rituals

Since Rook (1985) first described important linkages between rituals and consumer behavior, scholars have examined consumer rituals from the perspectives of the individual consumer, marketers, marketing exchanges, and cultural institutions. New modes of communication and expression (e.g., digital media), and globalization calls for a thorough understanding of the consumption-related ritual topics, and what areas they should explore in the future. In this paper, we systematically review articles in the top marketing and consumer behavior journals to provide an overview of the current composition of ritual scholarship, and of prospective areas for future research. In so doing, we hope to categorize ritual scholarship into broad conceptual domains and evaluate our current understanding of rituals in each, identify gaps in our understanding based on the changing market environment, and suggest areas of inquiry to address these gaps. We examined articles in the top twelve marketing journals identified in the SCImago Journal Rank of all marketing journals, each with an impact factor of at least 2.5. We searched for articles pertaining to consumption rituals in the twelve journals by consulting the three business databases included in the EBSCO database. Of these journals, five included pertinent articles: Journal of Marketing, Journal of Consumer Research, Journal of the Academy of Marketing Science, Journal of Consumer Psychology, and the Journal of Retailing. We determined that the authors’ foci led to an emergent partition of the literature into five domains (albeit with a few overlaps). The research team engaged in close reads and iterative discussion of articles, identifying various themes and research extensions within each domain. The themes are: foundational, macro-level, meso-level, marketplace-level, and micro-level

Consumers\u27 Management of Risk in Daily Life through Digital Virtual Consumption

The term “risky consumption” elicits visions of extreme contexts, such as leaping from a moving airplane at 30,000 feet above ground or using illicit hallucinogenic drugs. However, this study aims to answer the call for understanding risk that is inherent in consumers’risk-laden life events. Specifically, we examine the process by which consumers use digital virtual consumption (DVC) to negotiate tensions related to risk and the implications that this process holds for consumers’ identity narratives. Findings demonstrate how consumers, upon a triggering risk-laden life event, can turn to DVC to both cope with risk, as well as to engage in pleasurable risk. The research extends the theoretical understandings of risk and identity as intertwined with DVC. Managerial and social welfare implications are also offered

Astronomical Site Selection for Turkey Using GIS Techniques

A site selection of potential observatory locations in Turkey have been carried out by using Multi-Criteria Decision Analysis (MCDA) coupled with Geographical Information Systems (GIS) and satellite imagery which in turn reduced cost and time and increased the accuracy of the final outcome. The layers of cloud cover, digital elevation model, artificial lights, precipitable water vapor, aerosol optical thickness and wind speed were studied in the GIS system. In conclusion of MCDA, the most suitable regions were found to be located in a strip crossing from southwest to northeast including also a diverted region in southeast of Turkey. These regions are thus our prime candidate locations for future on-site testing. In addition to this major outcome, this study has also been applied to locations of major observatories sites. Since no goal is set for \textit{the best}, the results of this study is limited with a list of positions. Therefore, the list has to be further confirmed with on-site tests. A national funding has been awarded to produce a prototype of an on-site test unit (to measure both astronomical and meteorological parameters) which might be used in this list of locations.Comment: 17 pages, 10 figures, accepted by Experimental Astronom

Exploring Patient-Provider Relationships in Preference-Based Health Care Choices

Patient-physician relationship models previously identified in research do not always capture the full range of consumers’ experiences as they engage in difficult, preference-based decisions. Examining the context of individuals seeking infertility treatment, we identify a new Peripheral Model of patient-physician relationship, whereby the physician’s role is perceived as rather inconsequential
