Thompson, E.J. & Simon, B.K. (2012). A revision of Calyptochloa C.E.Hubb. (Poaceae), with two new species and a new subspecies. Austrobaileya 8(4): 634–652. Two new species of Calyptochloa C.E.Hubb. (Calyptochloa cylindrosperma E.J.Thomps. & B.K.Simon and C. johnsoniana E.J.Thomps. & B.K.Simon) endemic to central Queensland, and a new subspecies of Calyptochloa gracillima C.E.Hubb. (C. gracillima subsp. ipsviciensis E.J.Thomps. & B.K.Simon) endemic to southeast Queensland are described and illustrated.

Linkages of development and environment : in search of an integrated approach through sustainable development

Least developed countries (LDCs) are the primary victims of environmental changes, including present and future impacts of climate change. Environmental degradation poses a serious threat to the conservation and sustainable use of natural resources, thus hindering development in LDCs. Simultaneously, poverty is itself both a major cause and effect of global environmental problems. Against this backdrop, this essay argues that without recognition and protection of a collective right to development, genuine environmental protection will remain unachievable. Further, this essay submits that, particularly in the context of LDCs, the right to environment and the right to development are inseparable. Finally, this essay argues that the relationship between the right to environment and the right to development must fall within the paradigm of sustainable development if the promotion and protection of those rights are to be justified.

Regulating the coal industry : striking a balance between commercial and public interests - a Queensland case study

The coal industry in Queensland operates in a very complex regulatory environment with a matrix of Federal and State laws covering the environment, health and safety, taxation and royalties, tenure, and development approvals. The Queensland Government in 2012 recognised the validity of certain industry concerns and passed two Acts being the Environmental Protection (Greentape Reduction) Amendment Act 2012 (the Greentape Act) and the Mines Legislation (Streamlining) Amendment Act 2012 (the Streamlining Act). Other changes are foreshadowed in relation to overlapping tenure and in the development of common resources legislation. Accordingly there is a great level of activity and change that has occurred or which is on the horizon. This article focuses upon these regulatory changes and foreshadows other areas requiring consideration. It commences with a consideration of the changes that have already occurred, examines those regulatory amendments that are on the drawing board and concludes with suggestions as to further interventions and amendments that have the potential to enhance the efficiency and effectiveness of the legislative framework in which coal mining is conducted.

A hierarchical decomposition approach for coordinated dispatch of plug-in electric vehicles

Plug-in electric vehicles (PEVs) are increasingly popular in the global trend of energy saving and environmental protection. However, the uncoordinated charging of numerous PEVs can produce significant negative impacts on the secure and economic operation of the power system concerned. In this context, a hierarchical decomposition approach is presented to coordinate the charging/discharging behaviors of PEVs. The major objective of the upper-level model is to minimize the total cost of system operation by jointly dispatching generators and electric vehicle aggregators (EVAs). On the other hand, the lower-level model aims at strictly following the dispatching instructions from the upper-level decision-maker by designing appropriate charging/discharging strategies for each individual PEV in a specified dispatching period. Two highly efficient commercial solvers, namely AMPL/IPOPT and AMPL/CPLEX, respectively, are used to solve the developed hierarchical decomposition model. Finally, a modified IEEE 118-bus testing system including 6 EVAs is employed to demonstrate the performance of the developed model and method.

Introduction

This book explores the impacts of global economic, political and cultural shifts on various international legal frameworks and legal norms. The economic growth of states throughout Asia, South and Central America and Africa is having a profound effect on the dynamics of international relations, with a resulting impact on the operation and development of international law. This book examines the influence of emerging economies on international legal rules, institutions and processes. It describes recent and predicted changes in economic, political and cultural powers, flowing from the growth of emerging economies such as China, India, Brazil, South Africa and Russia, and analyses the influence of these changes on various legal frameworks and norms. Expert contributors drawn from a variety of fields, including international law, politics, environmental law, human rights, economics and finance, provide a broad analysis of the nature of the shifting global dynamic in its historical and contemporary contexts, and a range of perspectives on the impact of these changes as they relate to specific regimes and issues, including climate change regulation, collective security, indigenous rights, the rights of women and girls, environmental protection and foreign aid and development. The book provides a fresh and comprehensive analysis of an issue with extensive implications for international law and politics.

Ethics in Research with Children

Widespread scholarly interest in ethics in research with children, as an extant field of inquiry and practice, is a relatively new phenomenon. The discipline of ethics can be traced back to the Hippocratic school, but its contemporary applications in the everyday worlds of children and those around them are gaining greater attention from theorists, practitioners, and those involved in policy. Heightened international awareness of the United Nations Convention on the Rights of the Child (1979) gave significant impetus to increasing international awareness of children’s rights to provision, protection, and participation in everyday contexts, including those in which research occurs. Understandings of research ethics and of children’s involvement in research relate to broader understandings of children and childhood drawn from developmental science, sociology, human geography, health sciences, and children’s human rights to participation and protection. Key understandings pertain to children’s competence to participate in research, to operate as reliable informants with respect to their own lives, to provide voluntary informed consent and dissent in research, and to make meaningful decisions about the nature and extent of their participation. The field is international and interdisciplinary, although bounded by legislative, policy, and jurisdictional requirements governing research—its conduct and dissemination. So, too, the burgeoning work of ethics committees, whether in relation to health research or social research, is evidence of a sharpened focus on governance of child research. Oxford Bibliographies offers a suite of perspectives, resources, and strategies to guide the researcher, practitioner, and policymaker and serves to challenge readers to interrogate conceptual understandings, methodologies, and dissemination of research with and about children. Exploration of the suite opens up new possibilities for considering children’s rights to participation in matters that affect their lives and for children to be seen and heard in research.

Remote sensing and core data needed to support planning and policy decision making

A variety of sustainable development research efforts and related activities are attempting to reconcile the issues of conserving our natural resources without limiting economic motivation while also improving our social equity and quality of life. Land use/land cover change, occurring on a global scale, is an aggregate of local land use decisions and profoundly impacts our environment. It is therefore the local decision making process that should be the eventual target of many of the ongoing data collection and research efforts which strive toward supporting a sustainable future. Satellite imagery data is a primary source of data upon which to build a core data set for use by researchers in analyzing this global change. A process is necessary to link global change research, utilizing satellite imagery, to the local land use decision making process. One example of this is the NASA-sponsored Regional Data Center (RDC) prototype. The RDC approach is an attempt to integrate science and technology at the community level. The anticipated result of this complex interaction between research and the decision making communities will be realized in the form of long-term benefits to the public.

Wetlands : a perspective for mapping, monitoring, and modeling

Experience gained from numerous projects conducted by the U.S. Environmental Protection Agency's (EPA) Environmental Monitoring Systems Laboratory in Las Vegas, Nevada has provided insight to functional issues of mapping, monitoring, and modeling of wetland habitats. Three case studies in poster form describe these issues pertinent to managing wetland resources as mandated under Federal laws. A multiphase project was initiated by the EPA Alaska operations office to provide detailed wetland mapping of arctic plant communities in an area under petroleum development pressure. Existing classification systems did not meet EPA needs. Therefore a Habitat Classification System (HCS) derived from aerial photography was compiled. In conjunction with this photointerpretive keys were developed. These products enable EPA personnel to map large inaccessible areas of the arctic coastal plain and evaluate the sensitivity of various wetland habitats relative to petroleum development needs.

An overview of the role of goethite surfaces in the environment

Goethite, one of the most thermodynamically stable iron oxides, has been extensively researched especially the structure (including surface structure), the adsorption capacity to anions, organic/organic acid (especially for the soil organic carbon) and cations in the natural environment and its potential application in environmental protection. For example, the adsorption of heavy metals by goethite can decrease the concentration of heavy metals in aqueous solution and immobilize; the adsorption to soil organic carbon can decrease the release of carbon and fix carbon. In this present overview, the possible physicochemical properties of the goethite surface contributing to the strong affinity of goethite to nutrients and contaminants in natural environment are reported. Moreover, these chemicals adsorbed by goethite were also summarized and the suggested adsorption mechanism for these adsorbates was elucidated, which will help us understand the role of goethite in natural environment and provide some information about goethite as an absorbent. In addition, the feasibility of goethite used as catalyst carrier and the precursor of NZVI was proposed for removal of environmental pollution.

Identifying the spatial scale of land use that most strongly influences overall river ecosystem health score

Catchment and riparian degradation has resulted in declining ecosystem health of streams worldwide. With restoration a priority in many regions, there is an increasing interest in the scale at which land use influences stream ecosystem health. Our goal was to use a substantial data set collected as part of a monitoring program (the Southeast Queensland, Australia, Ecological Health Monitoring Program data set, collected at 116 sites over six years) to identify the spatial scale of land use, or the combination of spatial scales, that most strongly influences overall ecosystem health. In addition, we aimed to determine whether the most influential scale differed for different aspects of ecosystem health. We used linear-mixed models and a Bayesian model-averaging approach to generate models for the overall aggregated ecosystem health score and for each of the five component indicators (fish, macroinvertebrates, water quality, nutrients, and ecosystem processes) that make up the score. Dense forest close to the survey site, mid-dense forest in the hydrologically active nearstream areas of the catchment, urbanization in the riparian buffer, and tree cover at the reach scale were all significant in explaining ecosystem health, suggesting an overriding influence of forest cover, particularly close to the stream. Season and antecedent rainfall were also important explanatory variables, with some land-use variables showing significant seasonal interactions. There were also differential influences of land use for each of the component indicators. Our approach is useful given that restoring general ecosystem health is the focus of many stream restoration projects; it allowed us to predict the scale and catchment position of restoration that would result in the greatest improvement of ecosystem health in the regions streams and rivers. The models we generated suggested that good ecosystem health can be maintained in catchments where 80% of hydrologically active areas in close proximity to the stream have mid-dense forest cover and moderate health can be obtained with 60% cover.

Barriers to sustainable economic development : the Dallas–Fort Worth experience

This article examines the scope of existing economic development activity and the motivations and perceptions of practitioners to shed light on the barriers to sustainable practice. In contrast to related fields like urban planning, the economic development literature has minimally examined how practitioners think about sustainable development and the extent to which sustainable development principles are adopted in practice. This omission is significant because economic development policies can have a notable impact on the sustainable development goals of environmental protection and social equity alongside economic growth. To capture the extent to which economic developers engage in sustainable development and the barriers that practitioners face, we study fifteen cities in the Dallas–Fort Worth region. We find that six key barriers – a conventional economic development mindset, incentive-based practice, a lack of resources, ad hoc planning, inter-regional competition, and a lack of coordinated regional planning – impede sustainable economic development in the region.

Educating for the creative economy in emerging countries

In 1972, the United Nations (UN) Conference on the Human Environment expressed a growing realization that economic and social progress needed to be balanced with a concern for the environment and the stewardship of natural resources. The hard-to-grasp concept of "sustainable development" was first defined as "development that meets the needs of the present without compromising the ability of future generations to meet their needs" (World Commission on Environment and Development [WESDJ, 1987, p. 43). This definition contains two concepts: first, "human needs," with priority given to the world's poor, and, second, the environment's limits for meeting the state of technological and social organization (WESD, 1987, p. 43). At the 2002 World Summit on Sustainable Development (UN, 2002a), the focus on environmental protection broadened to encompass social justice and the fight against poverty as key principles of development that is sustainable. Three interdependent and mutually reinforcing "pillars" were recognized: economic development, social development, and environmental protection. These pillars must be established at local, national, and global levels. The complexity and interrelationship of critical issues such as poverty, wasteful consumption, urban decay, population growth, gender inequality, health, conflict, and the violation of human rights are addressed in all three pillars (Pigozzi, 2003, p. 3). Following the concept of sustainable development, we argue that the challenge for developing countries in contemporary society is to meet the very real need for economic development and opportunities for income generation, while avoiding the unintended and unwanted consequences of economic development and globalization. These consequences include social exclusion, loss of cultural heritage, and environmental and ecological problems.

Chinese economic development and the environment

Over the past two decades, China has become an economic powerhouse. However, as the world’s largest producer of CO2 emissions, the scale and seriousness of China’s environmental problems are clearly evident. This pioneering book provides an economic analysis of the significant environmental and energy problems facing China in the 21st century.

Mediated politics in Australia : towards a qualitative evaluation

The debate about the democratic significance of these trends—a more aggressively inquisitorial media environment, greater public participation in political communication, a more accessible and transparent (at least in appearance) political class—continues, not least in Australia. This essay was written in the first half of 2013, a time of extreme political volatility in Australia, and in the run-up to a general election following three years of minority Labor government. By that stage in the political cycle, Prime Minister Julia Gillard had survived not one but two attempts at leadership “spills”, ministers had resigned or been sacked for disloyalty to the leader, major policy initiatives had been dumped, reversed or quietly dropped, and a Coalition opposition was confidently looking forward to a landslide majority in the election of September that year. Labor’s internal party turmoil, rather than the Coalition’s policy prospectus (which remained sketchy and vague right up to the eve of the election), were widely assumed to be the cause of the former’s poor standing in the opinion polls.

Urban citizenship in a sensor rich society

Urban public spaces are sutured with a range of surveillance and sensor technologies that claim to enable new forms of ‘data based citizen participation’, but also increase the tendency for ‘function-creep’, whereby vast amounts of data are gathered, stored and analysed in a broad application of urban surveillance. This kind of monitoring and capacity for surveillance connects with attempts by civic authorities to regulate, restrict, rebrand and reframe urban public spaces. A direct consequence of the increasingly security driven, policed, privatised and surveilled nature of public space is the exclusion or ‘unfavourable inclusion’ of those considered flawed and unwelcome in the ‘spectacular’ consumption spaces of many major urban centres. In the name of urban regeneration, programs of securitisation, ‘gentrification’ and ‘creative’ and ‘smart’ city initiatives refashion public space as sites of selective inclusion and exclusion. In this context of monitoring and control procedures, in particular, children and young people’s use of space in parks, neighbourhoods, shopping malls and streets is often viewed as a threat to the social order, requiring various forms of remedial action. This paper suggests that cities, places and spaces and those who seek to use them, can be resilient in working to maintain and extend democratic freedoms and processes enshrined in Marshall’s concept of citizenship, calling sensor and surveillance systems to account. Such accountability could better inform the implementation of public policy around the design, build and governance of public space and also understandings of urban citizenship in the sensor saturated urban environment.
