Urban trees are an essential component of urban ecosystems, and management of this resource constitutes an essential element of urban open space management. However, municipal tree inventories in Sweden and elsewhere have received limited attention. It is unknown how common municipal tree inventories are in Sweden, factors governing whether a municipality has an inventory and what the inventories are used for. This study therefore sought to: Create an overview of the state of Swedish municipal tree inventories and determine how municipality size, green space budget and management organisation affect the presence and scope of municipal tree inventories. The research questions examined were: What is the current state of Swedish municipal tree inventories? and what affects the status of these municipal tree inventories? A survey with questions related to strategic and operational perspectives of municipal tree inventories, e.g. how they are conducted and used, together with questions relating to budget and potential use of consultants, was sent to all 290 Swedish municipalities. The response rate was 55.5%. The main findings were that municipality size affects whether a municipality has an urban tree inventory and that the municipal organisation form affects how inventories are used. The existence of an inventory also increased the probability of the municipality having a tree management plan. Based on these results we recommend further research related to strategic management perspectives of tree inventories. 相似文献

Consequences of governance restructuring for quality of urban living in the transformation era in Beijing: A view of job accessibility 总被引:2,自引:0,他引:2
One of the major issues concerning present-day public policy in a transitional and developing country is its ability to enhance the quality of urban living and individual social well-being in the context of rapid urban growth. A dramatic decline in overall job accessibility due to increases in commuting time is already a serious problem affecting the quality of urban living in Beijing. Understanding the impact of governance restructuring on overall job accessibility is of primary importance if politicians are to make policy innovations in development management. This paper applies the institutionalist approach to analyse the impact of governance restructuring on job accessibility. The analysis shows that current governance restructuring has a negative effect on overall job accessibility due to competition between different local governments increasing the degree of spatial fragmentation; revenue-enhancing development introducing constraints affecting the local jobs-housing balance; and the coexistence of the old planning system alongside the new market system leading to a fragmented land-use right transfer mechanism, intensifying scattered and low-density development. With respect to future policy, stronger municipal development management might be one direction in implementing public policy to enhance overall job accessibility, insofar as it addresses the negative impact of fragmented development management in the current transformation process. 相似文献

In this study, we construct a feasible region, in which we maximize the likelihood function, by using Shapiro–Wilk and Bartlett's test statistics to obtain Box–Cox power transformation parameter for solving the issues of non-normality and/or heterogeneity of variances in analysis of variance (ANOVA). Simulation studies illustrate that the proposed approach is more successful in attaining normality and variance stabilization, and is at least as good as the usual maximum likelihood estimation (MLE) in estimating the transformation parameter for different conditions. Our proposed method is illustrated on two real-life datasets. Moreover, the proposed algorithm is released under R package AID under the name of “boxcoxfr” for implementation. 相似文献

Previous research suggests that diverse factors predict gender differences in entrepreneurial intent. Our paper integrates and expands on previous findings using the Theory of Planned Behavior (TPB), including the deeper-level measurement model, allowing for a better understanding of the origin of differences. The results of a survey with business students indicate that the effect of gender on entrepreneurial intentions is mediated via personal attitudes and perceived behavioral control but not social norms. More precisely, vis-à-vis their male counterparts, women are more driven toward entrepreneurship by motives to ‘get organized’ (balance) that are less dominant in predicting personal attitude. Moreover, female students are somewhat less driven toward entrepreneurship by beliefs of internal control that are more dominant in predicting perceived control. Finally, while female students are also more motivated to comply with normative role models, this did not influence their entrepreneurial intentions over and above perceived behavioral control and personal attitude. We discuss both practical and theoretical implications of our findings. 相似文献

Some maintain that environmental factors are unimportant for infant and child survival once mother's education and other characteristics have been taken into account. However, an analysis of survival of African and Coloured children based on the 1994 October Household Survey supports the importance of environmental factors in relatively high mortality populations. Among African households, the source of domestic water is important, but for Coloured households, almost all of which have safe water, the type of sanitation is important. If safe drinking water is available, the type of sanitation influences survival; if safe drinking water is not available, sanitation seems to matter little. 相似文献

In the absence of a universally accepted method of calculating poverty, household expenditure can be used to provide an indication of inequality of wealth and serve as an indicator of poverty. Household expenditure comprises expenditure of private households on goods and services, irrespective of their durability. The portion of household budgets allocated to different types of goods and services provides an indication of the material standard of living of a population. The article discusses different definitions of poverty and compares the state of poverty according to these definitions in selected countries. This is followed by an analysis of South Africa’s economic position in the world and a comparison of the household budgets and demographic profile of South African households that fall into different income groups in order to identify the differences between the poorest and the wealthiest households in South Africa. Income inequality in South Africa is further elucidated by means of the Gini coefficient. A comparison is also made between the household budgets of the poorest households with the minimum financial living level requirements in South Africa to maintain their health and have acceptable standards of hygiene and sufficient clothing for their needs. 相似文献
