Abstract

The area of the Bjelovar Subdepression in Northern Croatia, which represents the southwestern part of Drava’s depression, has been analysed. More than 700°depth data were collected in a regular grid covering the existing structural maps of e-log markers Rs5, Z’ and Δ, with cells 2 x 2 km in size. For zonal assessment, Thiessen polygon method was used as introductory analysis preceding Kriging interpolation on regional scale. The emphasis was on OK and UK interpolation, their comparison and selection of most appropriate method for mapping. Crossvalidation results proved UK technique to be the most appropriate in mapping of e-log markers Rs5 and Δ, thus acquiring the most accurate maps so far of the analysed Neogene area.

Abstract

The suburbanisation of poverty has been noted in the cities of a large number of countries, including the UK. The main drivers are labour market restructuring on the one hand, and market-driven change in the housing system on the other although social and housing policies are also factors. This paper explores the possible consequences for the welfare of low-income groups in relation to two dimensions: exposure to air pollution and access to good quality schools. Results show that, for these groups, suburbanisation has had mixed impacts on welfare. In most cities, suburbanisation is likely to bring improvements in air quality but there are only a minority where it improves access to good quality schools. Overall, it is clear that suburbanising low income households enjoy fewer of the benefits of suburban locations than middle class households.

Abstract

The aim of the study was to evaluate the effect of different levels of dietary hybrid rye on eggs laid by Isa Brown laying hens and their quality, such as physical parameters and nutritional value (basic chemical composition, cholesterol content, fatty acid profile). A total of 72 Isa Brown hens aged 26 weeks were allocated to 3 groups fed with 0%, 15% and 25% levelsof hybrid rye in their diet up to week 50. At week 50, 72 eggs per group were collected for analysis. The 25% rye level had no significant effect on most of the examined physical parameters; however, a tendency to heavier eggs in this group was noted. An increased rye level resulted in lighter yolks with a lowered share of redness and yellowness compared to those obtained from hens fed a control diet. The administration of 25% of rye in the diet influenced the basic chemical composition of the yolks by increasing the water content and reducing the fat content, but with no significant effect on the contents of ash, chlorides and cholesterol. The sum of saturated fatty acids in yolks decreased along with the increase in dietary rye level while the sum of mono- and polyunsaturated fatty acids increased. Moreover, a lowered ratio of ω-6: ω-3 fatty acids was found with dietary rye level increases.

Abstract

Gentrification is no-longer, if it ever was, a small scale process of urban transformation. Gentrification globally is more often practised as large scale urban redevelopment. It is state-led or state-induced. The results are clear – the displacement and disenfranchisement of low income groups in favour of wealthier in-movers. So, why has gentrification come to dominate policy making worldwide and what can be done about it?

Abstract

This article presents the theory of focal locus applied to the hypersurfaces in the projective space which are (finitely) covered by linear spaces and such that the tangent space is constant along these spaces.

Summary

Results of ecological studies that involve the use of multivariate analysis of variance techniques for testing various hypotheses, interesting from the point of view of comparing the linear functions of parameters, were considered. For testing the most interesting hypotheses on a variety of interaction effects and on contrasts of class means, the application of a multivariate test statistic is recommended. Canonical variate analysis is used for graphical presentation of the results of multidimensional experiments. In this paper it is shown how a generalized form of canonical variate analysis can be useful to reveal which parametric functions of a multivariate analysis of variance model are responsible for rejecting the linear hypothesis. As an example, an analysis was made of an ecological study of trace element accumulation in plants of Italian ryegrass as a method of biomonitoring of air pollution.

Abstract

Based on fieldwork among Kurds in Norway, this article explores how participants described the presence of female genital cutting (FGC) in Kurdistan as a difficult topic to address in public. Perceptions of how FGC should be addressed ranged from acknowledging and directly confronting it to silencing and rejecting it as a Kurdish practice. The participants associated FGC with a “traditional mindset” and perceptions of female sexuality that did not readily fit into new ideologies of women’s liberation. Based on literature on how to manage a “difficult” characteristic in national identity construction, we argue that the participants’ negotiation of “modern” and “traditional” aspects of national identity is one strategy for dealing with FGC. FGC has the potential for spoiled national identity. However, we find reason to suggest that a condemnation of the practice based on women’s liberation may strengthen the aspects of Kurdish national aspirations that are grounded in human rights and gender equality.

Abstract

A comprehensive piece of research on the tools and methods available for public participation in urban development was carried out as part of the U_CODE Urban Collective Design Environment H2020-ICT Project, the results of which are presented in this paper. Approximately 70 methods and a range of participation goals were identified by investigating the publications of 20 cities and participation networks in Germany plus a number of online participation platforms. In the descriptions a general distinction was made between the level of involvement and the objective of participation. For most of the goals on informational or cooperation level, several (especially offline) tools were found to be available. For more ambitious objectives, e.g. massive co-design, no appropriate tools are currently market-ready, yet several research and development projects are targeting the development and testing of such means. The strong development of more complex methods and tools can be expected within the next few years. Often these instruments are designed in cooperation with urban authorities, however their broad application in German municipalities may take a couple of years yet.

Abstract

A significant workforce shortage of urologists available to serve the US population has been projected to occur over the next decade. Accordingly, much of the management of urologic patients will need to be assumed by other specialties and practitioners. Since primary care physicians are often first evaluate common urologic complaints, it makes sense that these physicians are in an excellent position to intervene in the management of these patients when appropriate. One of the most common complaints in urology is voiding dysfunction. The incidence of voiding dysfunction increases with age, with conservative estimates showing that over 50% of elderly patients suffer. Despite this high prevalence and its negative impact on quality of life, however, few seek or receive treatment, as many do not readily disclose these impactful yet personal symptoms. We sought to summarize the typical presentation, evaluation, assessment and therapeutic options for both male and female patients presenting with voiding dysfunction.

Abstract

The aim of this article is to provide the local convergence analysis of two novel competing sixth convergence order methods for solving equations involving Banach space valued operators. Earlier studies have used hypotheses reaching up to the sixth derivative but only the first derivative appears in these methods. These hypotheses limit the applicability of the methods. That is why we are motivated to present convergence analysis based only on the first derivative. Numerical examples where the convergence criteria are tested are provided. It turns out that in these examples the criteria in the earlier works are not satisfied, so these results cannot be used to solve equations but our results can be used.
