The area around Krakow airport is an attractive developmental urban area. The concentration of passenger traffic and the flow of goods is conducive to new development projects. These projects are associated with the operation of airports, as well as new uses which see the proximity of an airport as an additional asset in operating a business based on access to a form of high-speed transport. This paper presents the findings of research concerning the existing spatial structure, transport accessibility and compositional determinants within an area around Krakow Airport, which can be used to assess the phenomena present and formulate principles and trajectories of shaping them in the future. The study was based on an analysis of selected elements of the existing functio-spatial structure, as well as available materials and subject-specific planning documents. Due to the specificity of areas around airports, which undergo dynamic change, it appears key to determine the individual form of development and land cover, that skilfully combines modernity and comfort of use with meshing with the local landscape, featuring a network of linkages and the character of suburban space. The issues present in this area are distinctive of many cities and require coherent land development proposals.

Purpose – The purpose of this paper is to analyze the effects on urban flood from rapidly growing land and housing development projects in flood zones and water bodies in and around Dhaka. The paper further extends the analysis to generate an insight into Dhaka’s urban flood due to possible climate change effects on top of land and housing development projects effects. Design/methodology/approach – A mixed method was applied for this research comprising qualitative techniques for analyzing the date gathered from reviewing the policies including the Dhaka Metropolitan Development Plan reports, interviews, discussions and maps, whereas quantitative analysis was used to interpret the data gathered from the global positioning system (GPS) survey and questionnaire survey among the resident of the selected housing projects. Findings – Findings show that a large number of the projects have encroached flood-flow zones and ditches and drainage channels through massive land filling, which resulted in quick changes of land use with wide range of impacts on environment and habitat quality. This study highlighted that the potential climate change impact involves increasing rainfall and subsequent increase flooding. Besides, vast area will be submerged under water and increased warming in the city from high speed built-up area by unauthorized land development. Originality/value – The results of the research can be taken into consideration when making political decisions concerning adaptation to climate change.

Abstract Radial tires for automobiles were subjected to high speed rolling under load on a testing wheel to determine the critical speeds at which standing waves started to form. Tires of different makes had significantly different critical speeds. The damping coefficient and mass per unit length of the tire wall were measured and a correlation between these properties and the observed critical speed of standing wave formation was sought through use of a circular membrane model. As expected from the model, desirably high critical speed calls for a high damping coefficient and a low mass per unit length of the tire wall. The damping coefficient is particularly important. Surprisingly, those tire walls that were reinforced with steel cord had higher damping coefficients than did those reinforced with polymeric cord. Although the individual steel filaments are elastic, the interfilament friction is higher in the steel cords than in the polymeric cords. A steel-reinforced tire wall also has a higher density per unit length. The damping coefficient is directly related to the mechanical loss in cyclic deformation and, hence, to the rolling resistance of a tire. The study shows that, in principle, it is more difficult to design a tire that is both fuel-efficient and free from standing waves when steel cord is used than when polymeric cords are used.

The Impact

This article begins by discussing the specific industrial relations challenges of the highly competitive aviation industry. It then reflects on the outcome of the recent intense national debate over industrial relations, exploring the consequences of that debate for practice and policy, and discusses some key issues that remain in play. Although the Fair Work Act 2009 may have come about as a reaction to what many perceive as the ‘excesses’ of Work Choices, the new Act does not so much ‘wind back the clock’ as represent a significant new development in Australia’s long and unique industrial relations history. This article will discuss the impact of the changes, to date, made by the Fair Work Act on one organization, including the expansion of the ‘safety net’, and how the new compromise between the role of the ‘collective’ and the role of the ‘individual’ struck by the Act has the potential to fundamentally change the nature and structure of bargaining. We offer these comments as practitioners who have worked under successive industrial relations regimes since the early 1980s.

AbstractThe article approaches the topic of social trust from an evolutionary perspective. It begins by summarising the most influential approaches that have defined specific and social trust and ascertains what causes differences in degrees of trust and how the potential risk of deception might be lowered. It then notes that the basis of morality had already been formed during the era of prehistoric man, who was able to create coalitions against aggressors and to socially control the behaviour of deviants. It points out, however, that having a certain predisposition to behaving cooperatively or an increased sensitivity to recognising and not tolerating behaviour aimed at abusing cooperation is not a sufficient guarantee of the fact that people will always (or at least in the majority of situations) favour cooperation over deception. One of the reasons for this is a tendency to favour short-term gains over long-term ones. The article argues that establishing norms (moral, social and legal) produces a higher level of social trust because it not only “encourages” individuals to behave in certain ways in particular situations but also works as a sanction which “discourages” the individual from socially deviant behaviour. The article then focuses on a debate about the causal relationship between social trust and social capital. It discusses the suggestion that political institutions, government and the judiciary may reduce rather than raise levels of social capital and consequently also the level of social trust. This is partly because of their powerful position and the consequent scope for corruption and partly because of the fact that even when attempting to act honestly, representatives of these institutions cannot sufficiently reflect upon dynamic change at the local level. Finally, the article ends by adopting the position that social trust is built primarily from bottom up and so it is risky to continually doubt the very existence and usefulness of social norms and morality and to be governed simply by legal norms.

Land Cover Data

Soil loss due to surface erosion has been a global problem not just for developing countries but also for developed countries. One of the factors that have greatest impact on soil erosion is land cover. The purpose of this study is to estimate the long-term average annual soil erosion in the Lam Phra Phloeng watershed, Nakhon Ratchasima, Thailand with different source of land cover by using the Universal Soil Loss Equation (USLE) and GIS (30 m grid cells) to calculate the six erosion factors (R, K, L, S, C, and P) of USLE. Land use data are from Land Development Department (LDD) and ESA Climate Change Initiative (ESA/CCI) in 2015. The result of this study show that mean soil erosion by using land cover from ESA/CCI is less than LDD (29.16 and 64.29 ton/ha/year respectively) because soil erosion mostly occurred in the agricultural field and LDD is a local department that survey land use in Thailand thus land cover data from this department have more details than ESA/CCI.

And Diffusion

The rapid development of high-speed rail (HSR) and station areas has shortened the spatial and temporal distances among cities, improved the accessibility of cities, and affected the spatial agglomeration and diffusion of populations and of social and economic activities. This has led to spatial reconfiguration of production factors within cities, which has the potential to drive the reconstruction of urban spatial structures. Based on POI and land-use data, this paper defines the spatial scope of the HSR station area and explores the characteristics and influencing factors of its spatial structure from the perspective of industry. The study area i is set at 2000 m. Since the opening of the HSR, the industrial distribution has exhibited a significant circular, multi-core, and axial belt spatial structure. The spatial structure of each sub-industry is different. On the whole, internal and external transport and agglomeration economies have significant impacts on the industrial spatial distribution, and land rent has gradually decreased in importance with the development of HSR station areas. The intensity of the effects of different factors varies among different industries. The mechanisms by which the spatial structure of the station area is formed are discussed and include location accessibility, micro-market factors, node station attributes, the availability of a sufficient amount of undeveloped land, the characteristics and needs of HSR passengers, and policies and systems.
