The Impact

This study explores how rapid industrialization alongside a lack of regulatory controls through policy and planning encourages unplanned rapid urbanization in suburban areas. Taking Konabari–Kashimpur, a rapidly growing suburban area of the Greater Dhaka Region (GDR) as a case study, data has been collected through 16 key informant interviews and a questionnaire survey of 359 households in the area. The study finds that the readymade garment industry plays a significant role in the growth of this area. Negative externalities in the core area, the availability of large land parcels at a cheaper price, abundant labour supply and good transport connectivity to the core city make it favourable for industrialization. It is further found that industrialization and the forms of development taking place have largely occurred in an unplanned manner. Low-skilled and labour-intensive industry-driven growth has produced mixed-use intense development dominated by industrial and low-class residential uses. The impact of such growth on the suburban natural environment, infrastructure and society is found to be significant. The natural environment has been destroyed to provide land for industry and housing for workers. Basic service infrastructure and urban amenities have not increased proportionately to the growth of activities and the population. Moreover, the absence of a planning authority and land use regulations has worsened the situation further. It is concluded that the provision of basic infrastructure through planned intervention is required for sustainable urbanization.

Adult Unemployment

This paper describes the distribution of registered unemployment in Com monwealth Employment Service Offices within Sydney in the years 1971-79. In 1979 adult unemployment was concentrated in the centre of the urban area and teenage unemployment in the west. The greatly increased level of un employment since 1975 had not made major changes in this spatial pattern except in the case of adult female unemployment which in the early 1970s was concentrated in the western suburbs, but in the late '70s was highest in inner Sydney. The probable reason for this change is that when unemployment rates rose married women became discouraged workers and/or did not register as unemployed. As a result cyclical changes in the locations of concentrations of unemployed women may reflect imperfect data collection rather than economic causes. Real unemployment of adult women is probably still con centrated in suburban areas as is teenage unemployment while adult male unemployment is mainly a problem in the core of Sydney.

This paper attempts to analyse the trends of urbanization based on three-decade census data during 1991, 2001, and 2011 in Nagaur city. Various dimensions of urbanization have been studied through charts and diagrams. For this purpose, the urban parameters such as the growth rate of the urban population, gender dynamics, literacy rate, density, work, and economic structure of the Nagaur city have been examined. Results show that in these last three decades the urban structure of Nagaur city has been changed due to rapid industrialization and rural to urban migration. Urbanization in Nagaur has been relatively slow compared to many developing megacities. As per data released by Govt. of India, Nagaur is an Urban Agglomeration coming under the category of Class I UAs/Towns. According to trends, Nagaur is at the acceleration stage of the process of urbanization. Rapid urbanization raises many issues that might have both positive and negative impacts on the environment. In this situation, monitoring urbanization is vital for planners, management, government, and non-government organizations for implementing policies to optimize the use of natural resources and accommodate development at the same time minimizing the impact on the environment.

The Impact

Malaysia is one of the world's most successful ‘developing’ countries. As such it provides some excellent examples of rapidly changing man–environment relationships of a type that are soon to be expected in many other Third World nations.The examples selected for this paper have been chosen to show both the degree of Man's impact on the natural environment of Peninsular Malaysia and also the changing relationships between Man and his environment. These two themes are inextricably related. The case-studies used illustrate these themes on different areal scales.The impact of oil spillage from grounded supertankers using the Straits of Malacca and Singapore illustrates the international implications of a potentially widespread ecological disaster. The need for international control is stressed. In Malaysia, effluent from palm-oil processing mills is becoming an increasingly serious water-pollution problem in many of the Peninsula's rivers. Although the effects may be confined to individual drainage-basins, the results can be catastrophic to both aquatic and marine ecosystems and to the people who obtain their livelihood from them.Land development and forest clearance have resulted in the opening up of vast areas to new rural settlements, a process paralleled by rapid urbanization. The third case-study considers Man's changing relationship to his disease environment in both rural and urban areas from the point of view of man–mosquito relationships. Finally, as a local problem, the Batu Caves situation is taken to illustrate conflicting resource demands for a unique limestone habitat. The impact of industrial pollution on the local population is emphasized.These problems are finally considered from the point of view of the quality of life and human welfare in developing countries. It is argued that raising levels of human welfare through development without giving due consideration to environmental impact may be a self-defeating process. Local issues probably make the individual aware of this paradox. Perhaps only when the cumulative environmental and individual impact of human activities is appreciated at local, regional, and national, scales will effective legislative controls be introduced.

Vegetation cover is crucial for the sustainability of urban ecosystems; however, this cover has been undergoing substantial changes in cities. Based on climate data, city statistical data, nighttime light data and the Normalized Difference Vegetation Index (NDVI) dataset, we investigate the spatiotemporal variations of climate factors, urban lands and vegetation cover in 71 large cities of China during 1998–2012, and explore their correlations. A regression model between growing-season NDVI (G-NDVI) and urban land proportion (PU) is built to quantify the impact of urbanization on vegetation cover change. The results indicate that the spatiotemporal variations of temperature, precipitation, PU and G-NDVI are greatly different among the 71 cities which experienced rapid urbanization. The spatial difference of G-NDVI is closely related to diverse climate conditions, while the inter-annual variations of G-NDVI are less sensitive to climate changes. In addition, there is a negative correlation between G-NDVI trend and PU change, indicating vegetation cover in cities have been negatively impacted by urbanization. For most of the inland cities, the urbanization impacts on vegetation cover in urban areas are more severe than in suburban areas. But the opposite occurs in 17 cities mainly located in the coastal areas which have been undergoing the most rapid urbanization. Overall, the impacts of urbanization on G-NDVI change are estimated to be −0.026 per decade in urban areas and −0.015 per decade in suburban areas during 1998–2012. The long-term developments of cities would persist and continue to impact on the environmental change and sustainability. We use a 15-year window here as a case study, which implies the millennia of human effects on the natural biotas and warns us to manage landscapes and preserve ecological environments properly.

Background: The impact of concurrent osteoarthritis on mobility and mortality in individuals with Parkinson’s disease is unknown. Objective: We sought to understand to what extent osteoarthritis severity influenced mobility across time and how osteoarthritis severity could affect mortality in individuals with Parkinson’s disease. Methods: In a retrospective observational longitudinal study, data from the Parkinson’s Foundation Quality Improvement Initiative was analyzed. We included 2,274 persons with Parkinson’s disease. The main outcomes were the effects of osteoarthritis severity on functional mobility and mortality. The Timed Up and Go test measured functional mobility performance. Mortality was measured as the osteoarthritis group effect on survival time in years. Results: More individuals with symptomatic osteoarthritis reported at least monthly falls compared to the other groups (14.5% vs. 7.2% without reported osteoarthritis and 8.4% asymptomatic/minimal osteoarthritis, p = 0.0004). The symptomatic group contained significantly more individuals with low functional mobility (TUG≥12 seconds) at baseline (51.5% vs. 29.0% and 36.1%, p < 0.0001). The odds of having low functional mobility for individuals with symptomatic osteoarthritis was 1.63 times compared to those without reported osteoarthritis (p < 0.0004); and was 1.57 times compared to those with asymptomatic/minimal osteoarthritis (p = 0.0026) after controlling pre-specified covariates. Similar results hold at the time of follow-up while changes in functional mobility were not significant across groups, suggesting that osteoarthritis likely does not accelerate the changes in functional mobility across time. Coexisting symptomatic osteoarthritis and Parkinson’s disease seem to additively increase the risk of mortality (p = 0.007). Conclusion: Our results highlight the impact and potential additive effects of symptomatic osteoarthritis in persons with Parkinson’s disease.

Under the term “Hilfe zur Arbeit” (aid for work) the federal law of social welfare subsumes all kinds of labour disciplining instruments. First, the paper shows the historical connection of welfare and labour disciplining mechanisms in the context of different periods within capitalist development. In a second step, against the background of historical experiences, we will analyse the trends of “Hilfe zur Arbeit” during the past two decades. It will be shown that by the rise of unemployment, the impact of labour disciplining aspects of “Hilfe zur Arbeit” has increased both on the federal and on the municipal level. For this reason the leverage of the liberal paradigm would take place even in the core of social rights.

This chapter examines the impact of rapid urbanization and industrialization on food and eating out. It draws attention to the growing standardization of food and, with greater class differentiation, to the growing diversity in eating-out venues. Class, gender, and nation are again used as lenses to understand the different eating-out habits and their symbolic significance. Towards the end of the twentieth century, pubs moved more fully towards embracing dining. However, the quality of food, in general terms, began to improve significantly only towards the end of the century, and hospitality venues also moved towards selling food from diverse national origins.

Political conversation is at the heart of democratic societies, and it is an important precursor of political engagement. As society has become intertwined with the communication infrastructure of the Internet, we need to understand its uses and the implications of those uses for democracy. This chapter provides an overview of the core topics of scholarly concern around online citizen deliberation, focusing on three key areas of research: the standards of quality of communication and the normative stance on citizen deliberation online; the impact and importance of digital platforms in structuring political talk; and the differences between formal and informal political talk spaces. After providing a critical review of these three major areas of research, we outline directions for future research on online citizen deliberation.

Urban Recreation

Rapid urbanization promotes the expansion of urban tourism and recreation functions, but it also brings many problems, which affect residents’ happiness. Previous studies have emphasized the direct impact of urban recreation environment on happiness, and few have explored the indirect impact of urban recreation environment on happiness through subjective evaluation. Based on the survey data of nearly 10,000 permanent residents in 40 key tourism cities in China, this paper establishes a theoretical framework of the direct and indirect impact of urban recreation environment on happiness. The objective evaluation of natural recreation environment and sociocultural recreation environment has an important influence on happiness, but the influence of natural recreation environment is greater than that of sociocultural recreation environment. Individual subjective satisfaction with urban recreation environment mediates the relationship between urban objective environment and happiness. Urban parks have a positive effect on happiness, while tourist attractions have a negative effect. The influence of urban location on happiness is nonlinear. The high-income group is more sensitive to the recreation environment, while the low-income group is less sensitive to the recreation environment. These findings provide insights for further improving citizens’ quality of life and designing urban construction in developing countries under the conditions of rapid urbanization.

The Impact

Mechanical performance of 3d-printed polyamide sandwich beams with different type of the lattice cores is investigated. Four variants of the beams are considered, which differ in the type of connections between the elements in the lattice structure of the core. We consider the pantographic-type lattices formed by the two families of inclined beams placed with small offset and connected by stiff joints (variant 1), by hinges (variant 2) and made without joints (variant 3). The fourth type of the core has the standard plane geometry formed by the intersected beams lying in the same plane (variant 4). Experimental tests were performed for the localized indentation loading according to the three-point bending scheme with small span-to-thickness ratio. From the experiments we found that the plane geometry of variant 4 has the highest rigidity and the highest load bearing capacity in the static tests. However, other three variants of the pantographic-type cores (1–3) demonstrate the better performance under the impact loading. The impact strength of such structures are in 3.5–5 times higher than those one of variant 4 with almost the same mass per unit length. This result is validated by using numerical simulations and explained by the decrease of the stress concentration and the stress state triaxiality and also by the delocalization effects that arise in the pantographic-type cores.
