This report summarizes the results of a herpetofauna (reptile and amphibian) survey at Naval Station Rota (NAVSTA Rota), Spain conducted during June and October 2008, March 2009 and July 2010. The main objective of this investigation was to develop an inventory of herpetofauna, including their base-wide distribution and habitat use. Data from these surveys was used to supplement information in the 2010 Cultural/Natural Resources Management User's Guide and can also be used for environmental planning, natural resource management and conservation. Prior to this survey, only cursory field work had been conducted on the station for herpetofauna with the exception of the common chameleon (Chamaleo chamaeleon). A comprehensive population count and habitat assessment for the common chameleon was conducted in September 2001.

Species extinctions and the deterioration of other biodiversity features worldwide have led to the adoption of systematic conservation planning in many regions of the world. As a consequence, various software tools for conservation planning have been developed over the past twenty years. These, tools implement algorithms designed to identify conservation area networks for the representation and persistence of biodiversity features. Budgetary, ethical, and other sociopolitical constraints dictate that the prioritized sites represent biodiversity with minimum impact on human interests. Planning tools are typically also used to satisfy these criteria. This chapter reviews both the concepts and technical choices that underlie the development of these tools. Conservation planning problems can be formulated as optimization problems, and we evaluate the suitability of different algorithms for their solution. Finally, we also review some key issues associated with the use of these tools, such as computational efficiency, the effectiveness of taxa and abiotic parameters at choosing surrogates for biodiversity, the process of setting explicit targets of representation for biodiversity surrogates, and

Over 50% of the world's population live within 3. km of rivers and lakes highlighting the on-going importance of freshwater resources to human health and societal well-being. Whilst covering c. 3.5% of the Earth's non-glaciated land mass, trends in the environmental quality of the world's standing waters (natural lakes and reservoirs) are poorly understood, at least in comparison with rivers, and so evaluation of their current condition and sensitivity to change are global priorities. Here it is argued that a geospatial approach harnessing existing global datasets, along with new generation remote sensing products, offers the basis to characterise trajectories of change in lake properties e.g., water quality, physical structure, hydrological regime and ecological behaviour. This approach furthermore provides the evidence base to understand the relative importance of climatic forcing and/or changing catchment processes, e.g. land cover and soil moisture data, which coupled with climate data provide the basis to model regional water balance and runoff estimates over time. Using examples derived primarily from the Danube Basin but also other parts of the World, we demonstrate the power of the approach and its utility to assess the sensitivity of lake systems to environmental change, and hence better manage these key resources in the future.

This paper explores city dweller aspirations for cities of the future in the context of global commitments to radically reduce carbon emissions by 2050; cities contribute the vast majority of these emissions and a growing bulk of theworld's population lives in cities. The particular challenge of creating a carbon reduced future in democratic countries is that the measures proposed must be acceptable to the electorate. Such acceptability is fostered if carbon reduced ways of living are also felt to bewellbeing maximising. Thus the objective of the paper is to explore what kinds of cities people aspire to live in, to ascertain whether these aspirations align with or undermine carbon reduced ways of living, as well as personal wellbeing. Using a novel free associative technique, city aspirations are found to cluster around seven themes, encompassing physical and social aspects. Physically, people aspire to a city with a range of services and facilities, green and blue spaces, efficient transport, beauty and good design. Socially, people aspire to a sense of community and a safe environment. An exploration of these themes reveals that only a minority of the participants' aspirations for cities relate to lowering carbon or environmental wellbeing. Far more consensual is emphasis on, and a particular vision of, aspirations that will bring personal wellbeing. Furthermore, city dweller aspirations align with evidence concerning factors that maximise personal wellbeing but, far less, with those that produce lowcarbonways of living. In order to shape a lower carbon future that city dwellers accept the potential convergence between environmental and personal wellbeing will need to be capitalised on: primarily aversion to pollution and enjoyment of communal green space.

It has long been lamented that, although several disciplines contribute to career scholarship, they work in isolation from one another, thus denying career theory, research, and practice the benefits that multidisciplinary collaboration would bring. This constitutes a lost opportunity at a time when new understandings and approaches are needed in order to respond effectively to global changes in society and work. This book takes a major step towards remedying this situation by bringing together two key perspectives on career, the vocational psychological and the organisational (interpreted broadly to include organisation behaviour and human resource management). Written by international experts, the book opens by identifying some of the “tributaries” that flow into the “great delta of careers scholarship”, and noting the need to link what are at present separate “islands” of scholarship. It is structured to allow comparison between the ways in which the two perspectives address career development and career management theory, research and interventions. It concludes by pointing to the possibilities for dialogue, and even collaboration, between these perspectives, and suggesting ways in which these could be brought about. The book will be essential reading for career scholars because, with its potential to stimulate new thinking and developments in theory and research and also, importantly, in practice (with beneficial spin-offs for policy-makers), this dialogue could open a new phase in career scholarship. With its overviews of the history, theory, research and practice of both perspectives, the book will also be a valuable resource for students of both perspectives.

In recent years, there have been significant developments in climate science relevant to agriculture and natural resource management. Assessing impacts of climate variability and use of seasonal climate forecasts have become increasingly important elements in the management "toolkit" for many Australian farmers. Consideration of climate change further increases the need for improved management strategies. While climate risk extension activities have kept pace with advances in climate science, a national review of the Vocational Education and Training system in Australia in relation to "weather and climate" showed that these topics were "poorly represented" at the management level in the Australian Qualifications Framework, and needed increased emphasis. Consequently, a new Unit of Competency concerning management of climatic risk was developed and accredited to address this deficiency. The objective of the unit was to build knowledge and skills for better management of climate variability via the elements of surveying climatic and enterprise data; analysing climatic risks and opportunities; and developing climatic risk management strategies. This paper describes establishment of a new unit for vocational education that is designed to harness recent developments in applied climate science for better management of Australia's highly variable climate. The main benefits of the new unit of competency, "Developing climatic risk management strategies,"were seen as improving decisions in climate and agriculture, and reducing climate risk exposure to enhance sustainable agriculture. The educational unit is now within the scope of agricultural colleges, universities, and registered training organisations as an accredited unit.

Soils with high levels of chloride and/or sodium in their subsurface layers are often referred to as having subsoil constraints (SSCs). There is growing evidence that SSCs affect wheat yields by increasing the lower limit of a crop's available soil water (CLL) and thus reducing the soil's plant-available water capacity (PAWC). This proposal was tested by simulation of 33 farmers' paddocks in south-western Queensland and north-western New South Wales. The simulated results accounted for 79% of observed variation in grain yield, with a root mean squared deviation (RMSD) of 0.50 t/ha. This result was as close as any achieved from sites without SSCs, thus providing strong support for the proposed mechanism that SSCs affect wheat yields by increasing the CLL and thus reducing the soil's PAWC. In order to reduce the need to measure CLL of every paddock or management zone, two additional approaches to simulating the effects of SSCs were tested. In the first approach the CLL of soils was predicted from the 0.3-0.5 m soil layer, which was taken as the reference CLL of a soil regardless of its level of SSCs, while the CLL values of soil layers below 0.5 m depth were calculated as a function of these soils' 0.3-0.5 m CLL values as well as of soil depth plus one of the SSC indices EC, Cl, ESP, or Na. The best estimates of subsoil CLL values were obtained when the effects of SSCs were described by an ESP-dependent function. In the second approach, depth-dependent CLL values were also derived from the CLL values of the 0.3-0.5 m soil layer. However, instead of using SSC indices to further modify CLL, the default values of the water-extraction coefficient (kl) of each depth layer were modified as a function of the SSC indices. The strength of this approach was evaluated on the basis of correlation of observed and simulated grain yields. In this approach the best estimates were obtained when the default kl values were multiplied by a Cl-determined function. The kl approach was also evaluated with respect to simulated soil moisture at anthesis and at grain maturity. Results using this approach were highly correlated with soil moisture results obtained from simulations based on the measured CLL values. This research provides strong evidence that the effects of SSCs on wheat yields are accounted for by the effects of these constraints on wheat CLL values. The study also produced two satisfactory methods for simulating the effects of SSCs on CLL and on grain yield. While Cl and ESP proved to be effective indices of SSCs, EC was not effective due to the confounding effect of the presence of gypsum in some of these soils. This study provides the tools necessary for investigating the effects of SSCs on wheat crop yields and natural resource management (NRM) issues such as runoff, recharge, and nutrient loss through simulation studies. It also facilitates investigation of suggested agronomic adaptations to SSCs.

Concerns about excessive sediment loads entering the Great Barrier Reef (GBR) lagoon in Australia have led to a focus on improving ground cover in grazing lands. Ground cover has been identified as an important factor in reducing sediment loads, but improving ground cover has been difficult for reef stakeholders in major catchments of the GBR. To provide better information an optimising linear programming model based on paddock scale information in conjunction with land type mapping was developed for the Fitzroy, the largest of the GBR catchments. This identifies at a catchment scale which land types allow the most sediment reduction to be achieved at least cost. The results suggest that from the five land types modelled, the lower productivity land types present the cheapest option for sediment reductions. The study allows more informed decision making for natural resource management organisations to target investments. The analysis highlights the importance of efficient allocation of natural resource management funds in achieving sediment reductions through targeted land type investments. © 2012.

A discussão sobre a gestão é recente no Brasil, particularmente no âmbito da administração pública. As diretrizes do SUS são importantes instrumentos indutores de mudanças e modernização da gestão, incluindo aspectos relativos à organização da assistência, como sua humanização e também a busca de maiores níveis de desempenho e responsabilidade institucional para com os resultados alcançados. Diversos autores vêm se debruçando sobre o tema gestão, porém qual o modelo de gestão que conseguiria combinar um papel ativo, de liderança e de coordenação para gestores com autonomia? O presente trabalho tem por objetivo analisar a prática gerencial nos serviços de saúde do município de Piraí, buscando compreender as dimensões sociais e intersubjetivas de tais práticas, tendo como principal fonte as narrativa de seus gerentes. O município possui um contexto político peculiar, com uma continuidade política desde 1993, adota uma política de gestão participativa na saúde com várias instâncias formais e pratica um investimento em saúde acima do preconizado pela Constituição Federal o que permite um investimento em estruturação e oferta de serviços públicos. Do ponto de vista metodológico, o estudo adotou a abordagem de narrativas de vida, focalizando a gestão como um mundo social e expressão dos processos presentes nas organizações e que atravessam o relato dos entrevistados. Foram entrevistados quatro gerentes de unidades de saúde do município de Piraí. A análise do material empírico teve como um de seus eixos o estudo do percurso profissional dos gerentes, especialmente os processos que os levaram à função gerencial. A contingência marca essas trajetórias que se desenrolam em um contexto em que não existe qualquer exigência quanto à formação gerencial. Outro eixo abordado são as práticas gerenciais onde são examinados os sentidos que o exercício da função gerencial tem para os sujeitos, como também as suas estratégias de trabalho. O exame das práticas gerenciais norteia-se pela análise das possibilidades e limites para desencadear processos de mudança. Os depoimentos apontam as características destas experiências de gestão, que procuram construir condições para processos de mudança, seja através das experiências anteriores dessas gerentes ou das estratégias de trabalho e do sistema gerencial que procuram desenvolver. Os projetos profissionais de três das quatro entrevistadas vão claramente se definindo no âmbito da gestão: se veem, não mais como profissionais de sua área de formação original (enfermeira, médica), mas acima de tudo como gestores, alimentados pelo reconhecimento de suas capacidades de mobilização e de desenvolvimento de mudanças relativas a outras realizações no campo da gestão.

The purpose of this output was to use the results of the baseline and participatory diagnostics analysis to develop alternative innovations for agricultural production, natural resource management and food security. The farming systems in the project areas were analysed to identify the innovations that communities had been using for agricultural production, natural resource management and food security. The innovative strategies were examined for their contribution to sustainable agriculture, food security and natural resource management. Comparative analysis of the agricultural productivity, food security and natural resource management in the different areas where the innovations have been put in place was undertaken. The best practices would be identified, which should be scaled-up, modified or sustained. The willingness and perceptions of the farmers to adopt the innovations would then be assessed.

In this article, we argue that the history of bail foretells the future of parole. Under a plancalled the Conditional Post-Conviction Release Bond Act (recently passed into law inthree states), US prisoners can secure early release only after posting ‘post-convictionbail’. As with pre-trial bail, the fledgling model would require prisoners to pay a percent-age of the bail amount to secure their release under the contractual responsibility of acommercial bail agency. If release conditions are breached, bounty hunters are legallyempowered to seize and return the parolee to prison. Our inquiry outlines the origins of this post-conviction bond plan and the research upon which it is based. Drawing on the‘new penology’ framework, we identify several underlying factors that make for a ripeadvocacy environment and set the stage for widespread state-level adoption of this planin the near future. Post-conviction bail fits squarely within the growing policy trendstoward privatization, managerialism, and actuarial justice. Most importantly, though,advocates have the benefit of precedent on their side, as most US states have longrelied on a system of commercial bail bonding and private bounty hunting to manageconditional pretrial release.

Cette thèse comprend trois essais en économie de l’environnement et des ressources naturelles sous incertitude. Le premier essai propose un modèle de jeu différentiel qui analyse la pollution globale à travers la quête à l’hégémonie politique entre pays. Le second essai utilise des données boursières pour estimer une version stochastique de la règle de Hotelling et ainsi inférer sur le rôle des ressources naturelles non renouvelables dans la diversification du risque. Le troisième essai montre comment la prise en compte des perspectives futures modifie la règle de Hotelling dans un contexte de diversification du risque.
