Kinds of Management Policies Selected AbstractsTHE NEED FOR JOINED-UP DEBT MANAGEMENT POLICYECONOMIC AFFAIRS, Issue 1 2010Tim Congdon No abstract is available for this article. [source] A Retrospective Look at the Water Resource Management Policies in Nassau County, Long Island, New York,JOURNAL OF THE AMERICAN WATER RESOURCES ASSOCIATION, Issue 5 2008Daniel J. St. Germain Abstract:, The residents of Nassau County Long Island, New York receive all of their potable drinking water from the Upper Glacial, Jameco/Magothy (Magothy), North Shore, and Lloyd aquifers. As the population of Nassau County grew from 1930 to 1970, the demand on the ground-water resources also grew. However, no one was looking at the potential impact of withdrawing up to 180 mgd (7.9 m3/s) by over 50 independent water purveyors. Some coastal community wells on the north and south shores of Nassau County were being impacted by saltwater intrusion. The New York State Legislature formed a commission to look into the water resources in 1972. The commission projected extensive population growth and a corresponding increase in pumping resulting in a projected 93.5 to 123 mgd (4.1 to 5.5 m3/s) deficit by 2000. In 1986, the New York Legislature passed legislation to strengthen the well permit program and also establish a moratorium on new withdrawals from the Lloyd aquifer to protect the coastal community's only remaining supply of drinking water. Over 30 years has passed since the New York Legislature made these population and pumping projections and it is time to take a look at the accuracy of the projections that led to the moratorium. United States Census data shows that the population of Nassau County did not increase but decreased from 1970 to 2000. Records show that pumping in Nassau County was relatively stable fluctuating between 170 and 200 mgd (7.5 to 8.8 m3/s) from 1970 to 2004, well below the projection of 242 to 321 mgd (10.6 to 14.1 m3/s). Therefore, the population and water demand never grew to projected values and the projected threat to the coastal communities has diminished. With a stable population and water demand, its time to take a fresh look at proactive ground-water resource management in Nassau County. One example of proactive ground-water management that is being considered in New Jersey where conditions are similar uses a ground-water flow model to balance ground water withdrawals, an interconnection model to match supply with demand using available interconnections, and a hydraulic model to balance flow in water mains. New Jersey also conducted an interconnection study to look into how systems with excess capacity could be used to balance withdrawals in stressed aquifer areas with withdrawals in unstressed areas. Using these proactive ground-water management tools, ground-water extraction could be balanced across Nassau County to mitigate potential impacts from saltwater intrusion and provide most water purveyors with a redundant supply that could be used during water emergencies. [source] Baseline indicators for measuring progress in preventing falls injury in older peopleAUSTRALIAN AND NEW ZEALAND JOURNAL OF PUBLIC HEALTH, Issue 5 2009Annaliese M. Dowling Abstract Objective: Over recent years, there has been increasing attention given to preventing falls and falls injury in older people through policy and other initiatives. This paper presents a baseline set of fall injury outcome indicators against which these preventive efforts can be assessed in terms of monitoring the rate of fall-related deaths and hospitalisations. Methods: ICD-10-AM coded hospital separations, Australian Bureau of Statistics (ABS) mortality and ABS population data were used to determine the rate of fall-related injury mortality and hospitalisations occurring in people aged 65+ years in New South Wales (NSW), Australia, over the six-year period from 1998/99 to 2003/04, inclusive. Results: Baseline trends for one fatality and five separations-based metrics are presented. Overall, fall mortality rates increased over the six years, with higher rates in males. Falls hospitalisation rates also increased slightly, with higher rates in females. The rates of hip fracture and pelvic fracture hospital separations generally declined over the six years and were highest in females. The level of unspecified and missing information about the place where falls occur increased by 1.5%. Conclusion: Baseline trends in fall injury outcome metrics highlight the severity and frequency of fall injuries before wide scale implementation of the Management Policy to Reduce Fall Injury Among Older People in NSW. Implications: Future use of these metrics will help to evaluate and monitor the progress of falls prevention in older people in NSW. They could also be adopted in other jurisdictions.

[source] Designing Training Interventions: Human or Technical Skills Training?INTERNATIONAL JOURNAL OF TRAINING AND DEVELOPMENT, Issue 3 2001Eugenia N Petridou Training is seen as the key instrument in the implementation of Human Resource Management policies and practices in both the private and public sector. The choice of the type of training, focused on human or technical skills, is crucial in designing the training process. This field study investigates the personal and occupational characteristics of 444 public managers, candidates for human and technical skills training. A classification model is proposed which allows the selection and weighting of the candidate trainees' personal and occupational differences in order to participate in one of the two types of training. By means of the stepwise logistic regression method, gender, age, education, attitudes towards training, managerial level and job tenure have been identified as the significant variables associated with type of training. [source] Management Strategies and Improvement of Performance of Sewer NetworksCOMPUTER-AIDED CIVIL AND INFRASTRUCTURE ENGINEERING, Issue 7 2007Denys Breysse Even when they are conscious about the needs of maintenance to keep the system in a good condition, they lack efficient methods and tools that may help them in taking appropriate decisions. One can say that no really satisfactory and efficient tool exists, enabling the optimization of Inspection, Maintenance, or Rehabilitation (IMR) strategies on such systems. Sewer managers and researchers have been involved for many years in the French National Research Project for Renewal of Non Man Entry Sewer System (RERAU,Réhabilitation des Réseaux d'Assainissement Urbains, in French) to improve their knowledge of these systems and the management policies. During the RERAU project, a specific action has been dedicated to the modeling of asset ageing and maintenance. A special attention has been dedicated to the description of defects and dysfunctions, to the evaluation of performances and its modeling, accounting for its various dimensions (from the point of view of the manager, of the user, of the environment,). After having defined an Index of Technical Performance (ITp), we will introduce the Index of Technical and Economic Performance (ITEp) that is a combined measure of performance (including social costs) and technical costs. This index provides an objective standard tool for managers to compare different alternatives. It is used in the article to compare some simple IMR strategies. It sets the basis of a new method for no-man entry sewer system management, enabling us to analyze the profitableness of investment in terms of both technical and economic performance. [source] Robust Maintenance Policies for Markovian Systems under Model UncertaintyCOMPUTER-AIDED CIVIL AND INFRASTRUCTURE ENGINEERING, Issue 3 2006Kenneth D. Kuhn Many sources of error, some difficult to quantify, can limit the ability of asset management systems to accurately predict how built systems will deteriorate. This article introduces the use of robust optimization to deal with epistemic uncertainty. The Hurwicz criterion is employed to ensure management policies are never "too conservative." An efficient solution algorithm is developed to solve robust counterparts of the asset management problem. A case study demonstrates how the consideration of uncertainty alters optimal management policies and shows how the proposed approach may reduce maintenance and rehabilitation (M&R) expenditures. [source] Towards an autonomic approach for edge computingCONCURRENCY AND COMPUTATION: PRACTICE & EXPERIENCE, Issue 14 2007Mikael Desertot Abstract Nowadays, one of the biggest challenges for companies is to cope with the high cost of their information technologies infrastructure. Edge computing is a new computing paradigm designed to allocate on-demand computing and storage resources. Those resources are Web cache servers scattered over the ISP backbones. We argue that this paradigm could be applied for on-demand full application hosting, helping to reduce costs. In this paper, we present a J2EE (Java Enterprise Edition) dynamic server able to deploy/host J2EE applications on demand and its autonomic manager. For this, we reengineer and experiment with JOnAS, an open-source J2EE static server. Two management policies of the autonomic manager were stressed by a simulation of a worldwide ISP network.

[source] The Northwest Forest Plan as a Model for Broad-Scale Ecosystem Management: a Social PerspectiveCONSERVATION BIOLOGY, Issue 2 2006SUSAN CHARNLEY conservación y desarrollo; comunidades rurales; gestión forestal; monitoreo socioeconómico Abstract:,I evaluated the Northwest Forest Plan as a model for ecosystem management to achieve social and economic goals in communities located around federal forests in the U.S. Pacific Northwest. My assessment is based on the results of socioeconomic monitoring conducted to evaluate progress in achieving the plan's goals during its first 10 years. The assessment criteria I used related to economic development and social justice. The Northwest Forest Plan incorporated economic development and social justice goals in its design. Socioeconomic monitoring results indicate that plan implementation to achieve those goals met with mixed success, however. I hypothesize there are two important reasons the plan's socioeconomic goals were not fully met: some of the key assumptions underlying the implementation strategies were flawed and agency institutional capacity to achieve the goals was limited. To improve broad-scale ecosystem management in the future, decision makers should ensure that natural-resource management policies are socially acceptable; land-management agencies have the institutional capacity to achieve their management goals; and social and economic management goals (and the strategies for implementing them) are based on accurate assumptions about the relations between the resources being managed and well-being in local communities. One of the difficulties of incorporating economic development and social justice goals in conservation initiatives is finding ways to link conservation behavior and development activities. From a social perspective, the Northwest Forest Plan as a model for ecosystem management is perhaps most valuable in its attempt to link the biophysical and socioeconomic goals of forest management by creating high-quality jobs for residents of forest communities in forest stewardship and ecosystem management work, thereby contributing to conservation. Resumen:,Evalué el Plan Forestal del Noroeste como un modelo para la gestión de ecosistemas para alcanzar metas sociales y económicas en comunidades localizadas alrededor de bosques federales en el Pacífico Noroeste de E.U.A. Mi evaluación se basa en los resultados del monitoreo socioeconómico desarrollado para evaluar el progreso en el logro de las metas del plan durantes sus 10 primeros años. Los criterios de evaluación que utilicé se relacionan con el desarrollo económico y la justicia social. El diseño del Plan Forestal del Noroeste incorporó metas de desarrollo económico y de justicia social. Sin embargo, los resultados del monitoreo socioeconómico indican que éxito en la implementación del plan para alcanzar esas metas fue combinado. Postulé la hipótesis de que hay dos razones importantes por las que las metas socioeconómicas del plan no se cumplieron totalmente: algunas de las suposiciones clave en las estrategias de implementación fueron deficientes y la capacidad institucional de la agencia para alcanzar las metas era limitada. Para mejorar la gestión de ecosistemas a gran escala en el futuro, los tomadores de decisiones deberán asegurarse que las políticas de gestión de recursos naturales sean aceptables socialmente; que las agencias de gestión de tierras tengan la capacidad institucional para cumplir sus metas de gestión; y que las metas de gestión sociales y económicas (y las estrategias para su implementación) se basen en suposiciones precisas de las relaciones entre los recursos a gestionar y el bienestar de las comunidades locales. La manera de vincular comportamiento de conservación y actividades de desarrollo es una de las dificultades para la incorporación de metas de desarrollo económico y de justicia social en las iniciativas de conservación. Desde una perspectiva social, el Plan Forestal del Noroeste como modelo para la gestión de ecosistemas quizás es más valioso por su intento de vincular las metas biofísicas y socioeconómicas de la gestión forestal mediante la creación de empleos de alta calidad para residentes de las comunidades en labores de regulación y supervisión forestal y de gestión de ecosistemas, por lo tanto contribuye a la conservación. [source] Epidemiology of unarmed threats in the emergency departmentEMERGENCY MEDICINE AUSTRALASIA, Issue 4 2005Jonathan C Knott Abstract Objective:, To evaluate the precipitants, subject characteristics, nature and outcomes of unarmed threats in the ED. Methods:, A 12 month prospective survey of security codes precipitated by an unarmed threat (Code Grey). Results:, Data were collected on 151 subjects. The Code Grey rate was 3.2/1000 ED presentations. They were most frequent on Saturday and in the late evening/early morning. There were verbal or physical threats of violence made to staff on 104 occasions (69%, 95% confidence interval [CI] 61,76) and a perceived threat of patient self-harm on 114 occasions (76%, 95% CI 68,82). Median time to be seen by a doctor was 8 min (interquartile range [IQR]: 2,21 min) and median time from presentation to Code was 59 min (IQR: 5,222 min). Sixteen subjects (11%, 95% CI 6,17) had a history of violence, 45 (30%, 95% CI 23,38) were affected by alcohol, 25 (17%, 95% CI 11,24) had used illicit drugs and 79 (52%, 95% CI 44,60) had a significant mental illness contributing to the Code Grey. Seventy-one patients (47%, 95% CI 39,55) required psychiatric admission, 49 (79%, 95% CI 66,88) involuntarily. Conclusion:, Acutely agitated subjects pose a threat to themselves and the staff caring for them. The reason for the agitation is multifactorial and the majority arrive in a behaviourally disturbed state requiring early intervention. The times most likely to result in a Code Grey coincide with least available resources: ED and hospital risk management policies must account for this. A coherent approach by ED to this population is required to optimize patient and staff outcomes. [source] Climatic influences and anthropogenic stressors: an integrated framework for streamflow management in Mediterranean-climate California, U.S.A.FRESHWATER BIOLOGY, Issue 2010THEODORE E. GRANTHAM Summary 1. In Mediterranean and other water-stressed climates, water management is critical to the conservation of freshwater ecosystems. To secure and maintain water allocations for the environment, integrated water management approaches are needed that consider ecosystem flow requirements, patterns of human water demands and the temporal and spatial dynamics of water availability. 2. Human settlements in Mediterranean climates have constructed water storage and conveyance projects at a scale and level of complexity far exceeding those in other, less seasonal climates. As a result, multiple ecological stressors associated with natural periods of flooding and drying are compounded by anthropogenic impacts resulting from water infrastructure development. 3. Despite substantial investments in freshwater ecosystem conservation, particularly in California, U.S.A., success has been limited because the scales at which river management and restoration are implemented are often discordant with the temporal and spatial scales at which ecosystem processes operate. Often, there is also strong social and political resistance to restricting water allocation to existing consumptive uses for environmental protection purposes. Furthermore, institutions rarely have the capacity to develop and implement integrated management programmes needed for freshwater ecosystem conservation. 4. We propose an integrated framework for streamflow management that explicitly considers the temporal and spatial dynamics of water supply and needs of both human and natural systems. This approach makes it possible to assess the effects of alternative management strategies to human water security and ecosystem conditions and facilitates integrated decision-making by water management institutions. 5. We illustrate the framework by applying a GIS-based hydrologic model in a Mediterranean-climate watershed in Sonoma County, California, U.S.A. The model is designed to assess the hydrologic impacts of multiple water users distributed throughout a stream network. We analyse the effects of vineyard water management on environmental flows to (i) evaluate streamflow impacts from small storage ponds designed to meet human water demands and reduce summer diversions, (ii) prioritise the placement of storage ponds to meet human water needs while optimising environmental flow benefits and (iii) examine the environmental and social consequences of flow management policies designed to regulate the timing of diversions to protect ecosystem functions. 6. Thematic implications: spatially explicit models that represent anthropogenic stressors (e.g. water diversions) and environmental flow needs are required to address persistent and growing threats to freshwater biodiversity. A coupled human,natural system approach to water management is particularly useful in Mediterranean climates, characterised by severe competition for water resources and high spatial and temporal variability in flow regimes. However, lessons learned from our analyses are applicable to other highly seasonal systems and those that are expected to have increased precipitation variability resulting from climate change. [source] Gender and the Limits to Diversity in the Contemporary British ArmyGENDER, WORK & ORGANISATION, Issue 1 2006Rachel Woodward This article considers equal opportunities and diversity management policies in the contemporary British Army for what they indicate, not only about policy frameworks for women's military participation, but also for what they tell us about the construction of ideas about gender and difference within that organization. The article sets out contextual information on women in the British Army and describes the research methodology on which this article is based. It looks at the evolution of equal opportunities policies and the more recent shift towards diversity management policies in the Army, focusing on their contributions towards female equity. The article examines the consequences of the shift towards the management of diversity, noting how embracing the ideas of diversity management is ultimately limited by the Army's construction of female difference. It concludes with a discussion of the issues of female and military specificity in relation to the management of diversity. [source] The Sound of Silence: Valuing Acoustics in Heritage ConservationGEOGRAPHICAL RESEARCH, Issue 3 2008PENNY O'CONNOR Abstract This paper explores the reasons behind the omission of historic acoustic values from heritage assessments in Australia. Best practice dictates that all cultural heritage values associated with significant places should be assessed in order to make informed conservation and management decisions. However, the multi-sensory nature of aesthetics has been reframed in guidance documentation in ways that run counter to the primary frame. Conventions that have developed around the way places are assessed also work against comprehensive identification of values. As a result, the consideration of aesthetics in cultural heritage is limited to contemporary visual qualities. Furthermore, because the assessment of historic value takes a diachronic rather than synchronic approach, we have little knowledge of the places past communities valued for the sounds they experienced there. Research into landscape preference and acoustic ecology highlights the importance of identifying the inherent acoustic dimension of places and the role sound plays in developing a sense of place. Two landscape areas in Western Australia's south-west with historic acoustic values, the Boranup Sand Patch and the Lower Reaches of the Blackwood River, illustrate how historic soundscapes can provide insightful contrasts and resonances with contemporary values, and how vulnerable such places are when the sound of place is overlooked in land management policies. [source] Assessing forest growth across southwestern Oregon under a range of current and future global change scenarios using a process model, 3-PGGLOBAL CHANGE BIOLOGY, Issue 1 2001N. C. Coops Summary With improvements in mapping regional distributions of vegetation using satellite-derived information, there is an increasing interest in the assessment of current limitations on forest growth and in making projections of how productivity may be altered in response to changing climatic conditions and management policies. We utilised a simplified physiologically based process model (3-PG) across a 54 000 km2 mountainous region of southwestern Oregon, USA, to evaluate the degree to which maximum periodic mean annual increment (PAI) of forests could be predicted at a set of 448 forest inventory plots. The survey data were pooled into six broad forest types (coastal rain forest, interior coast range forest, mixed conifer, dry-site Douglas-fir, subalpine forest, and pine forest) and compared to the 3-PG predictions at a spatial resolution of 1 km2. We found good agreement (r2 = 0.84) between mean PAI values of forest productivity for the six forest types with those obtained from field surveys. With confidence at this broader level of integration, we then ran model simulations to evaluate the constraints imposed by (i) soil fertility under current climatic conditions, (ii) the effect of doubling monthly precipitation across the region, and (iii) a widely used climatic change scenario that involves modifications in monthly mean temperatures and precipitation, as well as a doubling in atmospheric CO2 concentrations. These analyses showed that optimum soil fertility would more than double growth, with the greatest response in the subalpine type and the least increase in the coastal rain forests. Doubling the precipitation increased productivity in the pine type (> 50%) with reduced responses elsewhere. The climate change scenario with doubled atmospheric CO2 increased growth by 50% on average across all forest types, primarily as a result of a projected 33% increase in photosynthetic capacity. This modelling exercise indicates that, at a regional scale, a general relationship exists between simulated maximum leaf area index and maximum aboveground growth, supporting the contention that satellite-derived estimates of leaf area index may be good measures of the potential productivity of temperate evergreen forests. [source] Spatial analysis of instream nitrogen loads and factors controlling nitrogen delivery to streams in the southeastern United States using spatially referenced regression on watershed attributes (SPARROW) and regional classification frameworks,HYDROLOGICAL PROCESSES, Issue 16 2009Anne B. Hoos Abstract Understanding how nitrogen transport across the landscape varies with landscape characteristics is important for developing sound nitrogen management policies. We used a spatially referenced regression analysis (SPARROW) to examine landscape characteristics influencing delivery of nitrogen from sources in a watershed to stream channels. Modelled landscape delivery ratio varies widely (by a factor of 4) among watersheds in the southeastern United States,higher in the western part (Tennessee, Alabama, and Mississippi) than in the eastern part, and the average value for the region is lower compared to other parts of the nation. When we model landscape delivery ratio as a continuous function of local-scale landscape characteristics, we estimate a spatial pattern that varies as a function of soil and climate characteristics but exhibits spatial structure in residuals (observed load minus predicted load). The spatial pattern of modelled landscape delivery ratio and the spatial pattern of residuals coincide spatially with Level III ecoregions and also with hydrologic landscape regions. Subsequent incorporation into the model of these frameworks as regional scale variables improves estimation of landscape delivery ratio, evidenced by reduced spatial bias in residuals, and suggests that cross-scale processes affect nitrogen attenuation on the landscape. The model-fitted coefficient values are logically consistent with the hypothesis that broad-scale classifications of hydrologic response help to explain differential rates of nitrogen attenuation, controlling for local-scale landscape characteristics. Negative model coefficients for hydrologic landscape regions where the primary flow path is shallow ground water suggest that a lower fraction of nitrogen mass will be delivered to streams; this relation is reversed for regions where the primary flow path is overland flow.

[source] Japan's strategic contributions to hydro-meteorological disaster mitigation in the world: planning to establish the UNESCO,PWRI CentreHYDROLOGICAL PROCESSES, Issue 6 2006Tetsuya Ikeda Hydro-meteorological disasters such as floods are major challenges that need to be overcome in order to realize sustainable development and poverty alleviation for humankind. Devastating flood disasters have occurring in various locations throughout the world, and there has recently been rising concern that the intensity and frequency of catastrophic floods may be increasing. Being located on the eastern edge of monsoonal Asia and having climatic variations according to the seasonal and regional conditions, Japan has long suffered from numerous flood disasters, and thus has developed advanced flood management policies. This paper aims to discuss flood disasters in Japan and the recently improved flood management policies. In addition, this paper introduces a new plan attempted by the Public Works Research Institute (PWRI) of Japan that takes advantage of the wealth of long accumulated experience and knowledge in the hydro-meteorological field. The PWRI is now working toward the establishment of an International Centre on Water-related Hazard and Risk Management by acquiring UNESCO's auspices. In order to contribute to the global challenge of reducing devastating hydro-meteorological disasters all over the world, this centre aims to conduct research, capacity-building and training programmes, and information networking activities at the local, national, regional and global levels. The aim is to prevent and mitigate hydro-meteorological disasters from the viewpoint of sustainable and integrated river basin management. Copyright © 2006 John Wiley & Sons, Ltd. [source] Development of an optimization model for energy systems planning in the Region of WaterlooINTERNATIONAL JOURNAL OF ENERGY RESEARCH, Issue 11 2008Y. P. Cai Abstract In this study, a large-scale dynamic optimization model (University of Regina Energy Model, UREM) has been developed for supporting long-term energy systems planning in the Region of Waterloo. The model can describe energy management systems as networks of a series of energy flows, transferring extracted/imported energy resources to end users through a variety of conversion and transmission technologies over a number of periods. It can successfully incorporate optimization models, scenario development and policy analysis within a general framework. Complexities in energy management systems can be systematically reflected; thus, the applicability of the modeling process can be highly enhanced. Four scenarios (including a reference case) are considered based on different energy management policies and sustainable development strategies for in-depth analysis of interactions existing among energy, socio-economy and environment in the Region. Useful solutions for the planning of energy management systems have been generated, reflecting trade-offs among energy-related, environmental and economic considerations. They are helpful for supporting (a) adjustment or justification of the existing allocation patterns of energy resources and services, (b) allocations of renewable energy resources, (c) formulation of local policies regarding energy consumption, economic development and energy structure, and (d) analysis of interactions among economic cost, system efficiency, emission mitigation and energy-supply security. Results also indicate that UREM can help tackle dynamic and interactive characteristics of the energy management system in the Region of Waterloo and can address issues concerning cost-effective allocation of energy resources and services. Thus, it can be used by decision makers as an effective technique in examining and visualizing impacts of energy and environmental policies, regional/community development strategies and emission reduction measures within an integrated and dynamic framework.

[source] Emigration from China: A Sending Country PerspectiveINTERNATIONAL MIGRATION, Issue 3 2003Xiang Biao This paper aims to provide a comprehensive overview of the policies pursued by the People's Republic of China (PRC) regarding the emigration of Chinese nationals. Most of the available literature on migration management has focused on receiving countries. With a few exceptions, little attention has been directed at migration management policies pursued in countries of origin. In the case of the PRC, policies regarding overseas Chinese have been fairly well documented and researched, but very little has been written about how the Chinese authorities manage ongoing emigration flows. This gap becomes particularly salient as the importance of the "partnership with the countries of origin" in devising migration policies is being increasingly acknowledged by receiving countries in Europe (Commission of the European Communities, 2000). Over the last 20 years, there have been significant changes in the Chinese Government's policies and perspectives on emigration. But, just like most other governments, the Chinese authorities do not have a single blanket policy covering all categories of emigrants. Emigration is normally managed on a case-by-case basis and the Government's attitude toward the same type of emigration may vary depending on different cases and circumstances. Because of this, this article examines China's major emigration-related policy spheres one by one. Specifically, six issues will be discussed: (1) exit control; (2) diaspora policy; (3) student migration; (4) labour export; (5) regulations on emigration agencies and, finally (6) the Government's response to human smuggling. This article shows both the coherence and the fragmentation in China's policies toward emigration. The coherence is due to the fact that all the policies are inherently linked to China's overall economic and social development strategy. The emigration management regime is sometimes fragmented partly because emigration consists of different streams and is handled by different Government departments, partly because some emigration issues (such as regulations on emigration agents) are very new for the Chinese Government and the authorities are still exploring them. Overall, the Chinese authorities increasingly see emigration as a means to enhance China's integration to the world and are keen to avoid conflicts with the international community over migration issues. At the same time, China's emigration policies need to be more balanced, in particular, the emigration of unskilled labour should be given more priority. [source] Portfolio selection on the Madrid Exchange: a compromise programming modelINTERNATIONAL TRANSACTIONS IN OPERATIONAL RESEARCH, Issue 1 2003E. Ballestero As a contribution to portfolio selection analysis, we develop a compromise programming approach to the investor's utility optimum on the Madrid Online Market. This approach derives from linkages between utility functions under incomplete information, Yu's compromise set, and certain biased sets of portfolios on the efficient frontier. These linkages rely on recent theorems in multi,criteria literature, which allow us to approximate the investor's utility optimum between bounds which are determined either by linear programming models or graphic techniques. Returns on 104 stocks are computed from capital gains and cash,flows, including dividends and rights offerings, over the period 1992,1997. The first step consists in normalizing the mean,variance efficient frontier, which is defined in terms of two indexes, profitability and safety. In the second step, interactive dialogues to elicit the investor's preferences for profitability and safety are described. In the third step, the utility optimum for each particular investor who pursues a buy,&,hold policy is bounded on the efficient frontier. From this step, a number of portfolios close to the investor's utility optimum are obtained. In the fourth step, compromise programming is used again to select one ,satisficing' portfolio from the set already bounded for each investor. This step is new with respect to previous papers in which compromise/utility models are employed. Computing processes are detailed in tables and figures which also display the numerical results. Extensions to active management policies are suggested. [source] 100 years of change: examining agricultural trends, habitat change and stakeholder perceptions through the 20th centuryJOURNAL OF APPLIED ECOLOGY, Issue 2 2009Martin Dallimer Summary 1The 20th century has witnessed substantial increases in the intensity of agricultural land management, much of which has been driven by policies to enhance food security and production. The knock-on effects in agriculturally dominated landscapes include habitat degradation and biodiversity loss. We examine long-term patterns of agricultural and habitat change at a regional scale, using the Peak District of northern England as a case study. As stakeholders are central to the implementation of successful land-use policy, we also assess their perceptions of historical changes. 2In the period 1900 to 2000, there was a fivefold rise in sheep density, along with higher cattle density. We found a reduction in the number of farms, evidence of a shift in land ownership patterns, and increased agricultural specialization, including the virtual disappearance of upland arable production. 3Despite previous studies showing a substantial loss in heather cover, we found that there had been no overall change in the proportion of land covered by dwarf shrub moor. Nonetheless, turnover rates were high, with only 55% of sampled sites maintaining dwarf shrub moor coverage between 1913 and 2000. 4Stakeholders identified many of the changes revealed by the historical data, such as increased sheep numbers, fewer farms and greater specialization. However, other land-use changes were not properly described. For instance, although there had been no overall change in the proportion of dwarf shrub moor and the size of the rural labour force had not fallen, stakeholders reported a decline in both. Spatial heterogeneity of the changes, shifting baselines and problems with historical data sources might account for some of these discrepancies. 5Synthesis and applications. A marked increase in sheep numbers, combined with general agricultural intensification, have been the dominant land-use processes in the Peak District during the 20th century. Stakeholders only correctly perceived some land-use changes. Policy and management objectives should therefore be based primarily on actual historical evidence. However, understanding stakeholder perceptions and how they differ from, or agree with, the available evidence will contribute to the successful uptake of land management policies and partly determine the costs of policy implementation. [source] The potential use of scales for estimating age and growth of Mediterranean albacore (Thunnus alalunga)JOURNAL OF APPLIED ICHTHYOLOGY, Issue 4 2003P. Megalofonou Summary The ability to accurately estimate the age of fishes is critical for conducting stock assessments and developing fishery management policies. Scales were collected from albacore, Thunnus alalunga, caught in the Mediterranean Sea during the years 1989,1995 to estimate their age and growth. Ages, which ranged from 1+ to 6+ years, were estimated from the interpretation of the concentric rings on the scales of 473 individuals that ranged in fork length from 55.5 to 89 cm. Males reached a greater size and age than females. The relatively close agreement in the mean lengths at ages estimated by scales and other techniques constituted a preliminary verification of the method. The von Bertalanffy growth model was fitted to mean lengths at estimated ages, resulting in the following growth parameters for the combined sexes: L, = 86 cm, K = 0.4, to = ,0.8 years. Parameter estimates were in agreement with what is known about life history of the species in the Mediterranean. Moreover, the growth rates were consistent with length increment observations from five tag returns, which lend support to our working hypothesis that the scale-rings are annual structures. When the Mediterranean albacore growth parameters were compared with those of Atlantic Ocean albacore using scale age estimates, there were significant differences between the two populations, and Mediterranean albacore remain significantly smaller than Atlantic Ocean albacore. [source] AN EMPIRICAL SURVEY OF RESIDENTIAL WATER DEMAND MODELLINGJOURNAL OF ECONOMIC SURVEYS, Issue 5 2008Andrew C. Worthington Abstract The increased reliance on demand-side management policies as an urban water consumption management tool has stimulated considerable debate among economists, water utility managers, regulators, consumer interest groups and policymakers. In turn, this has fostered an increasing volume of literature aimed at providing best-practice estimates of price and income elasticities, quantifying the impact of non-price water restrictions and gauging the impact of non-discretionary environmental factors affecting residential water demand. This paper provides a synoptic survey of empirical residential water demand analyses conducted in the last 25 years. Both model specification and estimation and the outcomes of the analyses are discussed.

A comparison of the influence of the various forms of urban containment and growth management policies with other "natural evolution,""flight from blight," and "fiscalization of land use" factors that also influence the square mile size of an urban area is made, and policy implications are offered.

MARTÍNEZ-CRUZ Abstract The fragmentation of a population may have important consequences for population genetic diversity and structure due to the effects of genetic drift and reduced gene flow. We studied the genetic consequences of the fragmentation of the Spanish imperial eagle (Aquila adalberti) population into small patches through a temporal analysis. Thirty-four museum individuals representing the population predating the fragmentation were analysed for a 345-bp segment of the mitochondrial control region and a set of 10 nuclear microsatellite loci. Data from a previous study on the current population (N = 79) were re-analysed for this subset of 10 microsatellite markers and results compared to those obtained from the historical sample. Three shared mitochondrial haplotypes were found in both populations, although fluctuations in haplotype frequencies and the occurrence of a fourth haplotype in the historical population resulted in lower current levels of haplotype and nucleotide diversity. However, microsatellite markers revealed undiminished levels of nuclear diversity. No evidence for genetic structure was observed for the historical Spanish imperial eagle population, suggesting that the current pattern of structure is the direct consequence of population fragmentation. Temporal fluctuations in mitochondrial and microsatellite allelic frequencies were found between the historical and the current population as well as for each pairwise comparison between historical and current Centro and historical and current Parque Nacional de Doñana nuclei. Our results indicate an ancestral panmictic situation for the species that management policies should aim to restore. A historical analysis like the one taken here provides the baseline upon which the relative role of recent drift in shaping current genetic patterns in endangered species can be evaluated and this knowledge is used to guide conservation actions. [source] REBUILDING THE EASTERN BALTIC COD STOCK UNDER ENVIRONMENTAL CHANGE (PART II): TAKING INTO ACCOUNT THE COSTS OF A MARINE PROTECTED AREANATURAL RESOURCE MODELING, Issue 1 2009CHRISTINE RÖCKMANN Abstract This study adds a cost analysis of the Eastern Baltic cod fishery to the existing model presented in Röckmann et al. [2007a]. As cost data on this international fishery do not exist, data from Denmark are extrapolated to the whole international fishery. Additionally, unit and total variable costs are simulated, and the sensitivity to a set of different cost,stock and cost,output elasticities is tested. The study supports preliminary conclusions that a temporary marine reserve policy, which focuses on protecting the Eastern Baltic cod spawning stock in the International Council for the Exploration of the Sea (ICES) subdivision 25, is a valuable fisheries management tool to (i) rebuild the overexploited Eastern Baltic cod stock and (ii) increase operating profits. The negative effects of climate change can be postponed for at least 20 years,depending on the assumed rate of future climate change. Including costs in the economic analysis does not change the ranking of management policies as proposed in the previous study where costs were neglected. [source] Irrigation water management policies: Allocation and pricing principles and implementation experienceNATURAL RESOURCES FORUM, Issue 2 2004Ariel Dinar Abstract Food security and sustainable development require efficient use of water resources, especially in irrigation. Economic pricing can be an effective tool to achieve more efficient water use, provided it is supported by other policies in implementation. Applying various water pricing and cost recovery arrangements is suggested for efficient allocation. Any adverse impact on farmers' incomes must be addressed and more reliable service must accompany higher prices. Experience from several countries suggests a variety of implementation issues. Essential complements to water pricing are water distribution rules and technological choices at critical nodes in the delivery system that allow farmers flexibility in conserving water in response to higher prices. Among supporting institutions, water users associations seem a higher priority than water markets. [source] Exomphalos , a major or minor problem?PEDIATRIC ANESTHESIA, Issue 9 2002T. O'Neill Introduction The mortality and morbidity statistics associated with exomphalos major remain discouraging despite advances in management techniques (1). Congenital lung pathology, in particular pulmonary hypoplasia, and thoracic maldevelopment, have been strongly allied to this condition, accounting for the high incidence of pulmonary insufficiency necessitating prolonged ventilatory support in these infants (2). We discuss the respiratory issues in an infant with a particularly severe form of exomphalos major, and the impact of a comprehensive parental website devoted to the infants' management and progress. Case Report A female infant, born at 38 weeks' gestation, was referred for management of exomphalos major. Due to the extensive nature of the abdominal wall defect, primary surgical closure was impossible and initial management consisted of staged reduction by external compression of the exomphalos. This resulted in escalating cardiovascular and respiratory embarrassment, and was abandoned in favour of conservative treatment, whereby the sac was dressed and allowed to epithelialise. Thereafter the clinical course was characterised by chronic pulmonary insufficiency requiring prolonged ventilatory support. Ventilator dependence did not significantly decrease until lung growth occurred and the sitting position was adopted, enabling weaning from conventional ventilation to genuine BIPAP at 6 months. Currently, after 11 months, we are preparing her for entry into a home ventilation programme. Throughout this period, progress and realistic goals were discussed at multidisciplinary case conferences involving the parents. The interpreted medical management has subsequently been displayed by the parents on an elaborate, up-to-date website, which is part of a larger ,Mother Of Omphalocele' network. Although innovative, this highlights the fact that we the medical profession, should be vigilant with regard to potential public exposure of patient management. Whilst the Internet has become an integral part of our own continuing education, this case highlights a new aspect of how it may be used by our patients and their relatives to compare and contrast management policies in various institutions. [source] Managing Diversity in U.S. Federal Agencies: Effects of Diversity and Diversity Management on Employee Perceptions of Organizational PerformancePUBLIC ADMINISTRATION REVIEW, Issue 1 2010Sungjoo Choi Diversity in the workplace is a central issue for contemporary organizational management. Concomitantly, managing increased diversity deserves greater concern in public, private, and nonprofit organizations. The authors address the effects of diversity and diversity management on employee perceptions of organizational performance in U.S. federal agencies by developing measures of three variables: diversity, diversity management, and perceived organizational performance. Drawing from the Central Personnel Data File and the 2004 Federal Human Capital Survey, their findings suggest that racial diversity relates negatively to organizational performance. When moderated by diversity management policies and practices and team processes, however, racial diversity correlates positively with organizational performance. Gender and age diversity and their interactions with contextual variables produce mixed results, suggesting that gender and age diversity reflect more complicated relationships. This article provides evidence for several benefits derived from effectively managing diversity. [source] Responsibility Budgeting at the Air Force Materiel CommandPUBLIC ADMINISTRATION REVIEW, Issue 1 2006Michael Barzelay The case study reported here challenges conventional wisdom about the feasibility of implementing responsibility budgeting and accounting practices in U.S. government. A variant of this practice took root and operated effectively in a large federal agency,the Air Force Materiel Command,during the period of study. Contrary to conventional wisdom, implementing a meaningful form of responsibility budgeting and accounting does not require changes in public management policies or systemic institutional reform. However, the evidence shows that instituting practices of responsibility budgeting and accounting may require considerable administrative ingenuity in adapting the generic practice to the situation at hand. [source] Treating water as an economic good: policies and practices in irrigation agriculture in Xinjiang, ChinaTHE GEOGRAPHICAL JOURNAL, Issue 2 2010SHEN YULING Since the 1990s, the idea that water should be treated as an economic good has become a widely acclaimed but also disputed principle. In Xinjiang, a dry region in north-west China, the idea has been translated into government water management policies and practices. Based on investigations in the Kaidu-Kongque River Basin, this paper describes how the idea is interpreted in concrete water fee policies and practices in local water management in irrigation agriculture, and discusses what problems exist in current water fee collection practices and expenditure, as well as in water management in irrigation agriculture. The main argument is that water management is deeply tied to the political, social and economic conditions of the state, and water pricing is part of the complex, diverse and changing social reality. In the study area, the interpretation of treating water as an economic good has not contributed to a fairer and more efficient use of scarce water resources, but rather it has been applied to achieve other political and economic goals as well as to strengthen a powerful and rapidly growing bureaucracy.
