Challenges for land system science

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.     

The ten commandments of legal risk management

Effective legal risk management is not a separate field of endeavor. Rather, it is inextricably linked with good management and with ethical management; managers who behave professionally and according to ethically defensible principles of action are quite unlikely to find themselves and their organizations stuck in a legal and/or ethical quagmire. Behavioral decision theory offers some explanations for why those managers who go astray do so, but explaining how basic human tendencies, uncorrected, may incline us to questionable decisions is not to justify such decisions. Managers who follow the guidelines set forth in this article may nonetheless find themselves or their companies under assault in the law courts or the court of public opinion, but should such an unlikely event occur, they will be far more likely to be able to successfully defend themselves.     

Combining biodiversity modeling with political and economic development scenarios for 25 EU countries

In the EURURALIS project, a chain of models was used to predict the changes in sustainable development indicators for European human well-being, ecology and economy issues, for four alternative scenarios of the future socio-economic development. This paper describes the biodiversity analysis of the project. Models based on general relationships between environmental factors and biodiversity loss were combined with socio-economic, land-use and environmental models to derive data that were integrated into an interactive tool for policy makers. The biodiversity analysis takes into account the effects of land-use change, climate change, fragmentation by major roads, area of unfragmented patches, nitrogen deposition, forestry and disturbance. Results show that biodiversity is projected to decrease between now and 2030 in most countries for all scenarios, indicating that it is unlikely that the EU will be able to fulfill its commitment to stop biodiversity loss by 2010. This is mainly due to urbanization and increase in stress factors, and outweighs the area increase of nature arising from land abandonment. Merits, limitations and uncertainties of this approach to biodiversity assessment are discussed.     

Examining the Decision Process of Students' Cheating Behavior: An Empirical Study

This research examines the association between attitudes on cheating and cognitive moral development. In this research, we use Rest's (1979a) Defining Issues Test, the Attitudes on Honesty Scale (Authors) and Academic Integrity Index (Authors); the last two are adaptations of the DIT. A total of 220 students from three universities participated in the study (66 psychology majors and 154 business majors). The data indicate that 66.4 percent of the students reported that they cheated in high school, college, or both high school and college. Psychology majors scored higher than business majors on both the Defining Issues Test (Rest, 1979a) and the Attitudes on Honesty Scale (AHS, Authors). Using factor analysis, we found significant associations between students' ratings of the importance considerations present in the three cheating scenarios and their estimates of whether cheating would occur (i.e., the Academic Integrity Index). Finally, using logistic regression, we found that the scores on the Attitudes on Honesty Scale and Academic Integrity Index associate with the self-reported cheating behavior of college students.     

Measuring physician contribution to the healthcare safety net

There are an estimated 46 million Americans without health insurance and an even larger number for whom health insurance does not cover all needed medical services. These individuals and families have to rely more and more on government programs and physicians’ willingness to provide uncompensated services, most often described by providers as charity care. Previous studies have shown a downward trend in the percent of physicians willing or able to provide charity care. We extend this research by examining the results of the Medical Group Management Association's Cost Survey of Medical Group Practices for 2005, 2006, and 2007. It is important to examine the uncompensated care reported by medical groups because groups have policies that may govern how much, if any, charity care their physicians provide. This survey data shows that, overall, the number of medical practices providing charity care continues to decline. The results and analysis of the survey data indicate that uncompensated (charity) care is being offered by less than half of medical practices, and at less than 2% of total gross charges. We examined the results by potential explanatory variables: population density, practice size, physician practice specialty, practice ownership structure, payer mix, and practice financial performance. Results were consistent across all categories; charity care is declining. These results have major policy implications for both the federal government and all state governments, especially in light of the current recession and proposed healthcare reform legislation.     

A rural typology for strategic European policies

The role that the agricultural sector plays in rural areas has considerably changed in the last five decades, and is reflected in a major shift towards multi-dimensional, multi-sectoral land use. Existing European rural typologies are mostly one-dimensional, based on a rather coarse administrative scale data and are unable to define adequately the diversity of the regions involved. The rural typology presented in this paper has been produced as a response to a new policy need for typologies addressing the diversity in regional rurality. This paper describes the method developed and explores the relevance of the results for future rural policies. This new rural typology incorporates two dimensions identified by statistical screening of a range of geographical and socioeconomic data related to the territorial variation of European rural land. The use of high-resolution raster data at 1 km² resolution provides large flexibility for the construction of individual classifications, with a variable number of classes for a variety of objectives. In the example presented, nine divisions were produced, which were subsequently summarised into three rural classes termed Peri-urban, Rural and Deep Rural. The rural typology enables the consistent identification of comparable rural areas and intergradations with urban land in the European territory, and describes the degree of generalisation that is possible. In addition, it provides a spatially explicit framework for scientific analysis and communication to both European policy makers and local stakeholders.     

Corporate Philanthropy in the U.K. 1985–2000 Some Empirical Findings

This paper briefly reviews the theories that seek to explain the phenomenon of corporate charitable donations and then provides a review of the empirical issues that have arisen in previous studies in this area. The findings of an analysis of charitable donations data from the entire U.K. FTSE index for the years 1985–2000 are then reported. These findings include the observation of a time-related increase in charitable donations, which is compared with an earlier study to give a 24 year history of charitable donations in the U.K. The findings note little responsiveness of the monetary value of charitable donations to the economic performance of firms. An international comparison over time against U.S. trends is also reported and shows how U.S. corporations have traditionally been more generous than U.K. firms, but that the trend in the U.S. is downwards. Membership of a U.K.-based "tithing" club (the PerCent Club) is shown to be associated with higher profit performance against non-members. Members' charitable contributions against profit are shown to be higher than the FTSE mean although short of the 0.5% target figure in "cash" terms. The paper concludes with a brief discussion of these findings in relation to the theoretical positions advanced for corporate philanthropy.
