Analysis of the land price development in the Ig municipality

In this graduation thesis there are represented some of the basic concepts in the field of real estate market and the factors that affect the price of the land property. A statistical analysis of land price on individual development stages in the Ig municipality in the period from the year 2007 to the year 2012 was made and described. The analysis is made on the basic data from the records of the property market, led by The Surveying and Mapping Authority of the Republic of Slovenia (Geodetska uprava Republike Slovenije or shorter GURS). GURS divides land property on four development stages: agricultural land, urbanized land for construction, developed land and land with building permission. During the earlier mentioned time period in Ig municipality only agricultural land, urbanized land for construction and land with building permission was traded with. Firstly the analysis results of price are made for the entire municipality, then for each of the cadastral zones and afterwards displayed in tables and graphs. In the thesis a special attention is dedicated to prices of agricultural land. I concluded they are very variable. Variability of agricultural land prices and consequently their average price is also affected by agricultural lands with known planning agendas. Prices of such agricultural lands are not considerably different from urbanized land prices for constructions. Therefore it would be sensible of GURS to add and separately monitor prices of a new development stage for agricultural lands

The Influence of Age, Gender, and Leisure on the Life Satisfaction of Widowed Older Adults

Spousal loss can be a stressful life event for older adults and a difficult experience that affects daily life and life satisfaction of older adults. Life satisfaction is considered an important part of successful aging. The purpose of this study was to examine how participation in leisure activities, a person’s gender, and time since spousal loss influence life satisfaction of widowed older adults. A sample of 222 widowed older adults selected from the Americans Changing Lives (ACL) dataset was used in order to determine the relationship and impact of predictor variables on time since spousal loss, change in physical leisure participation, and gender on changes in life satisfaction of widowed older adults. Correlation analysis showed no significant relationship between time since spousal loss and life satisfaction change; however, analyses of gender, age at time of spousal loss, and change in physical leisure participation resulted in statistically significant relationships. Further, the results of a multiple regression analysis suggest that age at time of loss, changes in physical participation, and being female are the greatest predictors of widowed older adults’ life satisfaction. Finally, gender does not seem to be a moderator between changes in physical participation and life satisfaction change. The meaningfulness of statistical significance of such results was explored and implications for these findings and suggestions for future research were discussed

Spreminjajoča se vloga učbenikov v osnovnošolskem izobraževanju v digitalni dobi: česa se lahko naučimo s pomočjo raziskav branja

Textbooks have been the primary teaching tool since the 19th century. By their nature, they contained a comprehensive compilation of the content of a particular subject with the intention of explaining it; this knowledge, in turn, was usually filtered to conform to a particular society’s expectations of elementary knowledge about the natural and social environments. There has been a great deal of research on how the content of textbooks has changed in line with changing values in different societies and over different periods. However, little research has been done on how textbook reading substrates and design have changed and how these changes have affected learning and comprehension: studies that systematically examined the effects of different reading substrates and different layouts on reading and learning comprehension did not appear until the late 20th century and early 21st century. We examine such studies and PISA 2021 results to draw five conclusions for future textbook research. These conclusions indicate that screens are worse than printed texts for some types of reading, while interactivity and dynamic design are not values per se but require coherent design to improve reading performance and higher-level thinking skills.

Application of amplitude thresholding to aid minimum energy adaptive subtraction for multiple attenuation

Model based multiple prediction approaches require an adaptive subtraction step that is able to correct for differences between the real and predicted multiples. The commonly used subtraction process derives shaping operators, in the least squares sense, to minimize the energy difference between the predicted multiples and the field record. Although the minimum energy assumption allows a computationally efficient adaptive subtraction, it can lead to attenuation of primary information. This abstract illustrates how a simple amplitude clipping approach can significantly improve the effectiveness of the least squares adaptive subtraction and minimize primary attenuation

Nickel exploration with 3D seismic - Lake Lefroy, Kambalda, WA

The first experimental 2D high resolution seismic reflection was recorded in 2005 over McLeay nickel deposits, Lake Lefroy, Kambalda, Western Australia. Seismic results indicated that these deposits may have a seismic signature. The complexity of the seismic pattern also suggested that 3D seismic may be necessary for exploration of McLeay deposits. Subsequent pilot high resolution 3D seismic survey conducted in 2007 confirmed the potential of reflection seismic for exploration at this site. Finally in 2008, a 10 Km2 high-resolution 3D seismic survey was acquired. Extreme conditions at the lake proved challenging for the application of seismic methods and required modification of the conventional seismic acquisition practice. In this paper we document and discuss acquisition and processing issues related to the specifics of the salt lake as well as the seismic signature of nickel deposits

Time-lapse borehole radar for monitoring rainfall infiltration through podosol horizons in a sandy vadose zone

The shallow aquifer on the Gnangara Mound, north of Perth, Western Australia, is recharged by winter rainfall. Water infiltrates through a sandy Podosol where cemented accumulation (B-) horizons are common. They are water retentive and may impede recharge. To observe wetting fronts and the influence of soil horizons on unsaturated flow, we deployed time-lapse borehole radar techniques sensitive to soil moisture variations during an annual recharge cycle. Zero-offset crosswell profiling (ZOP) and vertical radar profiling (VRP) measurements were performed at six sites on a monthly basis before, during, and after annual rainfall in 2011. Water content profiles are derived from ZOP logs acquired in closely spaced wells. Sites with small separation between wells present potential repeatability and accuracy difficulties. Such problems could be lessened by (i) ZOP saturated zone velocity matching of time-lapse curves, and (ii) matching of ZOP and VRP results.The moisture contents for the baseline condition and subsequent observations are computed using the Topp relationship. Time-lapse moisture curves reveal characteristic vadose zone infiltration regimes. Examples are (I) full recharge potential after 200 mm rainfall, (II) delayed wetting and impeded recharge, and (III) no recharge below 7 m depth. Seasonal infiltration trends derived from long-term time-lapse neutron logging at several sites are shown to be comparable with infiltration trends recovered from time-lapse crosswell radar measurements. However, radar measurements sample a larger volume of earth while being safer to deploy than the neutron method which employs a radioactive source. For the regime (III) site, where time-lapse radar indicates no net recharge or zero flux to the water table, a simple water balance provides an evapotranspiration value of 620 mm for the study period. This value compares favorably to previous studies at similar test sites in the region. Our six field examples demonstrate application of time-lapse borehole radar for characterizing rainfall infiltration
