In efforts to promote transitions to sustainability in city-regions, government and nongovernment actors throughout the world are devising comprehensive sustainability strategies and implementing a variety of environmental policies. Social actors in many city-regions view forest stewardship as an important element of this integrated approach. Generally, urban sustainability goals are guided by the principles of ecological integrity, environmental quality, social equity, social inclusion, and social justice. In other words, sustainable urban development should foster a good quality of life for all by providing equitable access to adequate economic opportunity, housing, education, public services, ecosystem services, and environmental amenities. Governance structures should pursue these goals democratically with legitimacy, transparency, and accountability. Effective sustainability planning and management depend on the reliability of land-use monitoring and modeling approaches. They also require field-based, qualitative empirical research to understand the complex social dynamics that are invisible from space. The aim of this paper is to encourage international, cross-disciplinary dialogue on the conceptual, theoretical, methodological, and practical groundwork necessary to effectively carry out metropolitan land-change science, particularly for rapidly expanding small- and medium-sized cities in developing countries. I begin by presenting the paper's central conceptual and theoretical framework. Next, I explore existing analytical and methodological approaches to the study of land-use dynamics in metropolitan regions. After a brief discussion of specific opportunities and challenges for collaborative, interdisciplinary research in support of metropolitan land-change science, I conclude by proposing a four-part agenda for coordinated investigation of tropical and subtropical forest recovery in city-regions worldwide.  相似文献

While the literature has suggested the possibility of breach being composed of multiple facets, no previous study has investigated this possibility empirically. This study examined the factor structure of typical component forms in order to develop a multiple component form measure of breach. Two studies were conducted. In study 1 (N = 420) multi-item measures based on causal indicators representing promissory obligations were developed for the five potential component forms (delay, magnitude, type/form, inequity and reciprocal imbalance). Exploratory factor analysis showed that the five components loaded onto one higher order factor, namely psychological contract breach suggesting that breach is composed of different aspects rather than types of breach. Confirmatory factor analysis provided further evidence for the proposed model. In addition, the model achieved high construct reliability and showed good construct, convergent, discriminant and predictive validity. Study 2 data (N = 189), used to validate study 1 results, compared the multiple-component measure with an established multiple item measure of breach (rather than a single item as in study 1) and also tested for discriminant validity with an established multiple item measure of violation. Findings replicated those in study 1. The findings have important implications for considering alternative, more comprehensive and elaborate ways of assessing breach.  相似文献

Contrasting approaches to assessing the performance of public services highlight important issues for policy-makers and future research. We need systematic comparisons between countries. We should use a broader range of evidence. The public ought to have a greater role in designing performance criteria, and we need to know more about the impacts of assessments.  相似文献

Both the UK and the US have rapidly ageing and increasingly diverse populations very dependent on driving. A comparative study commissioned by the UK Department for Transport found that in both the UK and the US adult children of older drivers, whilst often concerned about their parents’ continued driving, were also worried about the burden they would carry when their parents stopped driving, although there were differences by race and ethnicity. This study suggests that a policy window may be opening through which babyboomers can advocate for a range of driver training, roadway and vehicle improvements, expansion and enhancement of traditional public transportation and community transport options, improvements in accessibility and pedestrian infrastructure, and supportive land use and housing policies that would allow older people to drive safely longer, and, find meaningful mobility options when they can no longer drive. Policy responses must recognise and respond appropriately to differences by race and ethnicity.  相似文献

This paper evaluates the role of economic geography in explaining regional wages in China. It investigates the extent to which market proximity can explain the evolution of wages, and through which channels. We construct a complete indicator of market access at the provincial level from data on domestic and international trade flows; this is introduced in a simultaneous-equations system to identify the direct and indirect effect of market access on wages. The estimation results for 29 Chinese provinces over 1995–2002 suggest that access to sources of demand is indeed an important factor shaping regional wage dynamics in China. We investigate three channels through which market access might influence wages beside direct transport-cost savings: export performance, and human and physical capital accumulation. A fair share of benefits seems to come from enhanced export performance and greater accumulation of physical capital. The main source of influence of market access remains direct transport costs.  相似文献

Employee resistance has long been recognized as a key constraint on the success of organizational change initiatives. However, it is only recently that employee attitudes towards working in teams has been specifically investigated as a factor influencing team effectiveness. Using data from 218 employees in 40 self-managing work teams, we examined the relationship between trust, individualism, job characteristics and team members' attitudes towards teamwork. Providing a partial test of Mayer et al.'s (1995) relational model of trust, the results indicate that the two situational forms of trust (trust in co-workers and trust in management) were stronger predictors of an employee's preference for teamwork than propensity to trust. Trust in co-workers was found to partially mediate the relationship between a person's propensity to trust strangers and their preference for working in a team. The importance of considering the dispositional variables of propensity to trust and individualism as factors that influence an employee's preference for teamwork, as well as their trust in management, trust in co-workers and their opportunity for skill utilization are discussed.  相似文献

Although previous research has underscored the significance of the personality traits of frontline employees (FLEs) in employee service behaviors, knowledge about customer preferences for FLE personality traits is lacking. This study responds to this gap in the literature, empirically assessing customers’ preferences for FLE personality traits. The main research objective is to investigate whether and how these preferences vary with the customer's own personality. The study proposes and tests a conceptual framework that reconciles two opposing theoretical perspectives—homophily and heterophily. The existing research in interpersonal psychology has only given limited support to the heterophily effect, whereas it has consistently evidenced the homophily effect. Moderator analyses indicate these effects are largely invariant across customer and service characteristics. Notwithstanding this, post hoc tests show that the level of preferred FLE traits is positively related to the level of customer traits. Equity theory helps explain these seemingly conflicting results.  相似文献

Challenges for land system science   总被引:3,自引:0,他引:3  
While considerable progress has been made in understanding land use change, land system science continues to face a number of grand challenges. This paper discusses these challenges with a focus on empirical land system studies, land system modelling and the analysis of future visions of land system change. Contemporary landscapes are contingent outcomes of past and present patterns, processes and decisions. Thus, empirical analysis of past and present land-use change has an important role in providing insights into the socio-economic and ecological processes that shape land use transitions. This is especially important with respect to gradual versus rapid land system dynamics and in understanding changes in land use intensity. Combining the strengths of empirical analysis with multi-scale modelling will lead to new insights into the processes driving land system change. New modelling methods that combine complex systems thinking at a local level with macro-level economic analysis of the land system would reconcile the multi-scale dynamics currently encapsulated in bottom-up and top-down modelling approaches. Developments in land use futures analysis could focus on integrating explorative scenarios that reflect possible outcomes with normative visions that identify desired outcomes. Such an approach would benefit from the broad and in-depth involvement of stakeholders in order to link scientific findings to political and societal decision-making culminating in a set of key choices and consequences. Land system models have an important role in supporting future land use policy, but model outputs require scientific interpretation rather than being presented as predictions. The future of land system science is strongly dependent on the research community's capacity to bring together the elements of research discussed in the paper, via empirical data collection and analysis of observed processes, computer simulation across scale levels and futures analysis of alternative, normative visions through stakeholder engagement.  相似文献

This article evaluates whether expanding Medicare to cover those between ages 55 and 64 will improve the health status of these near-elderly individuals. We compare the experiences of near-elderly and elderly women with breast cancer and pay special attention to those demographic groups traditionally thought to be disadvantaged. Using unique individual-level data from the National Cancer Institute, we find that expanding Medicare does not improve the probability that a black woman will have her cancer diagnosed early. However, if she does happen to be diagnosed early, a discretE-time hazard model of survival finds that the price effects of insurance will improve her odds of survival.  相似文献
