Making ecological science policy relevant: issues of scale and disciplinary integration

In this paper, we ask why so much ecological scientific research does not have a greater policy impact in the UK. We argue that there are two potentially important and related reasons for this failing. First, much current ecological science is not being conducted at a scale that is readily meaningful to policy-makers. Second, to make much of this research policy-relevant requires collaborative interdisciplinary research between ecologists and social scientists. However, the challenge of undertaking useful interdisciplinary research only re-emphasises the problems of scale: ecologists and social scientists traditionally frame their research questions at different scales and consider different facets of natural resource management, setting different objectives and using different language. We argue that if applied ecological research is to have greater impact in informing environmental policy, much greater attention needs to be given to the scale of the research efforts as well as to the interaction with social scientists. Such an approach requires an adjustment in existing research and funding infrastructures.

The People’s Republic of China and Latin America: the impact of Chinese economic growth on Latin American exports

The role of the People’s Republic of China in the world economy has grown substantially in recent decades, turning it into a strategic foreign trading partner for much of Latin America. Bilateral trade between the region and China totalled US$ 120 billion in 2009. This study analyses the income elasticity of the region’s exports to the country. The findings show that, assuming real gross domestic product (gdp) growth in China of about 7% a year, the value of Latin American exports to China (at 2005 prices) can be expected to increase by an average of about 10% a year between 2014 and 2019. In a more conservative scenario of 4.5% average annual growth in the Chinese economy over the period, exports would rise by about 7% a year.

Environmental weathering of natural and artificial stones used in historical architecture: influence of microstructure and new restoration methods

For some study cases (the Cathedral of Modena, Italy, XII-XIV century; the Ducal Palace in Mantua, Italy, XVI century; the church of San Francesco in Fano, Italy, XIV-XIX century), considered as representative of the use of natural and artificial stones in historical architecture, the complex interaction between environ-mental aggressiveness, materials’ microstructural characteristics and degradation was investigated. From the results of such analyses, it was found that materials microstructure plays a fundamental role in the actual extent to which weathering mechanisms affect natural and artificial stones. Consequently, the need of taking into account the important role of material microstructure, when evaluating the environmental aggressiveness to natural and artificial stones, was highlighted. Therefore, a possible quantification of the role of microstructure on the resistance to environmental attack was investigated. By exposing stone samples, with significantly different microstructural features, to slightly acidic aqueous solutions, simulating clean and acid rain, a good correlation between weight losses and the product of carbonate content and specific surface area (defined as the “vulnerable specific surface area”) was found. Alongside the evaluation of stone vulnerability, the development of a new consolidant for weathered carbonate stones was undertaken. The use of hydroxya-patite, formed by reacting the calcite of the stone with an aqueous solution of di-ammonium hydrogen phosphate, was found to be a promising consolidating tech-nique for carbonates stones. Indeed, significant increases in the mechanical prop-erties can be achieved after the treatment, which has the advantage of simply con-sisting in a non-hazardous aqueous solution, able to penetrate deeply into the stone (> 2 cm) and bring significant strengthening after just 2 days of reaction. Furthermore, the stone sorptivity is not eliminated after treatment, so that water and water vapor exchanges between the stone and the environment are not com-pletely blocked.

Comparative study about the use of two and three-dimensional methods in surface finishing characterization

The increasing number of works related to the surface texture characterization based on 3D information, makes convenient rethinking traditional methods based on two-dimensional measurements from profiles. This work compares results between measurements obtained using two and three-dimensional methods. It uses three kinds of data sources: reference surfaces, randomly generated surfaces and measured. Preliminary results are presented. These results must be completed trying to cover a wider number of possibilities according to the manufacturing process and the measurement instrumentation since results can vary quite significantly between them.

Human Rights in the Democratic People's Republic of Korea and the Future of the Troubled State after Kim Jong-Il

Since 2008, international speculation about the viability of Kim Jong-Il's leadership in North Korea has been at the forefront of diplomatic discussions. North Korea is known to be a secretive state where human rights violations abound. This paper discusses the history of leadership and government in North Korea since World War II, the current human rights situation in the country, the role of China, and potential successors to Kim Jong-Il. The ramifications of impending regime change are discussed in terms of North Korea's human rights issues and economic problems. While current efforts at diplomacy have proved ineffective, the need for concerned nations, intergovernmental organizations, and non-governmental organizations to be prepared to engage North Korea after Kim Jong-Il is imperative.
