Evaluation of a high temperature solar thermal seasonal borehole storage

A solar thermal system with seasonal borehole storage for heating of a residential area in Anneberg, Sweden, approximately 10 km north of Stockholm, has been in operation since late 2002. Originally, the project was part of the EU THERMIE project ���Large-scale Solar Heating Systems for Housing Developments��� (REB/0061/97) and was the first solar heating plant in Europe with borehole storage in rock not utilizing a heat pump. Earlier evaluations of the system show lower performance than the preliminary simulation study, with residents complaining of a high use of electricity for domestic hot water (DHW) preparation and auxiliary heating. One explanation mentioned in the earlier evaluations is that the borehole storage had not yet reached ���steady state��� temperatures at the time of evaluation. Many years have passed since then and this paper presents results from a new evaluation. The main aim of this work is to evaluate the current performance of the system based on several key figures, as well as on system function based on available measurement data. The analysis show that though the borehole storage now has reached a quasi-steady state and operates as intended, the auxiliary electricity consumption is much higher than the original design values largely due to high losses in the distribution network, higher heat loads as well as lower solar gains.

Russian Arctic Ports : Problems with the development and management of tourist flows

The potential changes to the territory of the Russian Arctic open up unique possibilities for the development of tourism. More favourable transport opportunities along the Northern Sea Route (NSR) create opportunities for tourism development based on the utilisation of the extensive areas of sea shores and river basins. A major challenge for the Russian Arctic sea and river ports is their strong cargo transport orientation originated by natural resource extraction industries. A careful assessment of the prospects of current and future tourism development is presented here based on the development of regions located along the shores of the Arctic ocean (including Murmansk and Arkhangelsk oblast, Nenets Autonomous okrug (AO), Yamal-Nenets AO, Taymyr AO, Republic of Sakha, Chykotsky AO). An evaluation of the present development of tourism in maritime cities suggests that a considerable qualitative and quantitative increase of tourism activities organised by domestic tourism firms is made virtually impossible. There are several factors contributing to this. The previously established Soviet system of state support for the investments into the port facilities as well as the sea fleet were not effectively replaced by creation of new structures. The necessary investments for reconstruction could be contributed by the federal government but the priorities are not set towards the increased passenger transportation. Having in mind, increased environmental pressures in this highly sensitive area it is especially vital to establish a well-functioning monitoring and rescue system in the situation of ever increasing risks which come not only from the increased transports along the NSR, but also from the exploitation of the offshore oil and gas reserves in the Arctic seas. The capacity and knowledge established in Nordic countries (Norway, Finland) concerning cruise tourism should not be underestimated and the already functioning cooperation in Barents Region should expand towards this particular segment of the tourism industry. The current stage of economic development in Russia makes it clear that tourism development is not able to compete with the well-needed increase in the cargo transportation, which means that Russia���s fleet is going to be utilised by other industries. However, opening up this area to both local and international visitors could contribute to the economic prosperity of these remote areas and if carefully managed could sustain already existing maritime cities along the shores of the Arctic Ocean.

Reliability of GPS based traffic data: an experimental evaluation

GPS tracking of mobile objects provides spatial and temporal data for a broad range of applications including traffic management and control, transportation routing and planning. Previous transport research has focused on GPS tracking data as an appealing alternative to travel diaries. Moreover, the GPS based data are gradually becoming a cornerstone for real-time traffic management. Tracking data of vehicles from GPS devices are however susceptible to measurement errors ��� a neglected issue in transport research. By conducting a randomized experiment, we assess the reliability of GPS based traffic data on geographical position, velocity, and altitude for three types of vehicles; bike, car, and bus. We find the geographical positioning reliable, but with an error greater than postulated by the manufacturer and a non-negligible risk for aberrant positioning. Velocity is slightly underestimated, whereas altitude measurements are unreliable.

Self-reported conflict management competence among nursing students on the point of graduating and registered nurses with professional experience

Objective: It has been shown that specific competence is necessary for preventing and managing conflicts in healthcare settings. The aim of this descriptive and correlation study was to investigate and compare the self-reported conflict management competence (CMC) of nursing students who were on the point of graduating (NSPGs), and the CMC of registered nurses (RNs) with professional experience. Methods: The data collection, which consisted of soliciting answers to items measuring CMC in the Nurse Professional Competence (NPC) Scale, was performed as a purposive selection of 11 higher education institutions (HEIs) in Sweden. Three CMC items from the NPC Scale were answered by a total of 569 nursing students who were on the point of graduating and 227 RN registered nurses with professional experience. Results: No significant differences between NSPGs and RNs were found, and both groups showed a similar score pattern, with the lowest score for the item: ���How do you perceive your ability to develop the group and strengthen competence in conflict management and problem-solving, based on knowledge of group dynamics?���. RNs with long professional experience (>24 months) rated their overall CMC as significantly better than RNs with short (<24 months) professional experience did (p = .05). NSPGs who had experience of international studies during their nursing education reported higher CMC, compared with those who did not have this experience (p = .03). RNs who reported a high degree of utilisation of CMC during the previous month scored higher regarding self-reported overall CMC (p < .0001). Conclusions: Experience of international studies during nursing education, or long professional experience, resulted in higher self-reported CMC. Hence, the CMC items in the NPC Scale can be suitable for identifying self-reported conflict management competence among NSPGs and RNs

Process evaluation of a knowledge translation intervention using facilitation of local stakeholder groups to improve neonatal survival in the Quang Ninh province, Vietnam

BACKGROUND: Annually, 2.8 million neonatal deaths occur worldwide, despite the fact that three-quarters of them could be prevented if available evidence-based interventions were used. Facilitation of community groups has been recognized as a promising method to translate knowledge into practice. In northern Vietnam, the Neonatal Health - Knowledge Into Practice trial evaluated facilitation of community groups (2008-2011) and succeeded in reducing the neonatal mortality rate (adjusted odds ratio, 0.51; 95��% confidence interval 0.30-0.89). The aim of this paper is to report on the process (implementation and mechanism of impact) of this intervention. METHODS: Process data were excerpted from diary information from meetings with facilitators and intervention groups, and from supervisor records of monthly meetings with facilitators. Data were analyzed using descriptive statistics. An evaluation including attributes and skills of facilitators (e.g., group management, communication, and commitment) was performed at the end of the intervention using a six-item instrument. Odds ratios were analyzed, adjusted for cluster randomization using general linear mixed models. RESULTS: To ensure eight active facilitators over 3��years, 11 Women's Union representatives were recruited and trained. Of the 44 intervention groups, composed of health staff and commune stakeholders, 43 completed their activities until the end of the study. In total, 95��% (n���=���1508) of the intended monthly meetings with an intervention group and a facilitator were conducted. The overall attendance of intervention group members was 86��%. The groups identified 32 unique problems and implemented 39 unique actions. The identified problems targeted health issues concerning both women and neonates. Actions implemented were mainly communication activities. Communes supported by a group with a facilitator who was rated high on attributes and skills (n���=���27) had lower odds of neonatal mortality (odds ratio, 0.37; 95��% confidence interval, 0.19-0.73) than control communes (n = 46). CONCLUSIONS: This evaluation identified several factors that might have influenced the outcomes of the trial: continuity of intervention groups' work, adequate attributes and skills of facilitators, and targeting problems along a continuum of care. Such factors are important to consider in scaling-up efforts.

Evaluation of the Conservation Lands of Maine Based on Presence of Habitat Suitable for Listed Species

���Conservation Lands��� include both public and private lands that are devoted to the protection of wildlife and natural resources. ���Listed Species��� include federally and state endangered and threatened animals that are in danger of extermination in the state of Maine. The purpose of this study is to determine how well conservation lands are protecting the habitats of listed species. GAP data was used for 13 terrestrial vertebrate species indicating the presence or absence of suitable habitats. This data was compiled in GIS, generating a layer showing the number of listed species an area is suitable for. The areas that were suitable for at least one habitat were compared to answer three questions: (1) Is there is a difference between the presence and absence of listed species on protected lands and lands that are not protected? (2) Is there is a difference between the presence and absence of listed species on public lands managed by the state and the federal government and private land? (3) Is there is a difference between the presence and absence of listed species on lands protected under easements and lands that are protected fee simple? We found significant differences between all three categories. Conservation lands, private lands, and lands held under easement protect the habitat of listed species most effectively. We believe that this is due to the large number of private land trusts in the state of Maine and the effective management strategies of state lands.

Model Configuration And Data Management In The Short-Term Water Information Forecasting Tools

The Short-term Water Information and Forecasting Tools (SWIFT) is a suite of tools for flood and short-term streamflow forecasting, consisting of a collection of hydrologic model components and utilities. Catchments are modeled using conceptual subareas and a node-link structure for channel routing. The tools comprise modules for calibration, model state updating, output error correction, ensemble runs and data assimilation. Given the combinatorial nature of the modelling experiments and the sub-daily time steps typically used for simulations, the volume of model configurations and time series data is substantial and its management is not trivial. SWIFT is currently used mostly for research purposes but has also been used operationally, with intersecting but significantly different requirements. Early versions of SWIFT used mostly ad-hoc text files handled via Fortran code, with limited use of netCDF for time series data. The configuration and data handling modules have since been redesigned. The model configuration now follows a design where the data model is decoupled from the on-disk persistence mechanism. For research purposes the preferred on-disk format is JSON, to leverage numerous software libraries in a variety of languages, while retaining the legacy option of custom tab-separated text formats when it is a preferred access arrangement for the researcher. By decoupling data model and data persistence, it is much easier to interchangeably use for instance relational databases to provide stricter provenance and audit trail capabilities in an operational flood forecasting context. For the time series data, given the volume and required throughput, text based formats are usually inadequate. A schema derived from CF conventions has been designed to efficiently handle time series for SWIFT.

Volunteered Geographic Information For Water Management: A Prototype Architecture

Driven by Web 2.0 technology and the almost ubiquitous presence of mobile devices, Volunteered Geographic Information (VGI) is knowing an unprecedented growth. These notable technological advancements have opened fruitful perspectives also in the field of water management and protection, raising the demand for a reconsideration of policies which also takes into account the emerging trend of VGI. This research investigates the opportunity of leveraging such technology to involve citizens equipped with common mobile devices (e.g. tablets and smartphones) in a campaign of report of water-related phenomena. The work is carried out in collaboration with ADBPO - Autorit�� di bacino del fiume Po (Po river basin Authority), i.e. the entity responsible for the environmental planning and protection of the basin of river Po. This is the longest Italian river, spreading over eight among the twenty Italian Regions and characterized by complex environmental issues. To enrich ADBPO official database with user-generated contents, a FOSS (Free and Open Source Software) architecture was designed which allows not only user field-data collection, but also data Web publication through standard protocols. Open Data Kit suite allows users to collect georeferenced multimedia information using mobile devices equipped with location sensors (e.g. the GPS). Users can report a number of environmental emergencies, problems or simple points of interest related to the Po river basin, taking pictures of them and providing other contextual information. Field-registered data is sent to a server and stored into a PostgreSQL database with PostGIS spatial extension. GeoServer provides then data dissemination on the Web, while specific OpenLayers-based viewers were built to optimize data access on both desktop computers and mobile devices. Besides proving the suitability of FOSS in the frame of VGI, the system represents a successful prototype for the exploitation of user local, real-time information aimed at managing and protecting water resources.

Evaluation Of Reservoir Model Integration With Deterministic And Probabilistic Streamflow Forecasts

Due to the increase in water demand and hydropower energy, it is getting more important to operate hydraulic structures in an efficient manner while sustaining multiple demands. Especially, companies, governmental agencies, consultant offices require effective, practical integrated tools and decision support frameworks to operate reservoirs, cascades of run-of-river plants and related elements such as canals by merging hydrological and reservoir simulation/optimization models with various numerical weather predictions, radar and satellite data. The model performance is highly related with the streamflow forecast, related uncertainty and its consideration in the decision making. While deterministic weather predictions and its corresponding streamflow forecasts directly restrict the manager to single deterministic trajectories, probabilistic forecasts can be a key solution by including uncertainty in flow forecast scenarios for dam operation. The objective of this study is to compare deterministic and probabilistic streamflow forecasts on an earlier developed basin/reservoir model for short term reservoir management. The study is applied to the Yuvac��k Reservoir and its upstream basin which is the main water supply of Kocaeli City located in the northwestern part of Turkey. The reservoir represents a typical example by its limited capacity, downstream channel restrictions and high snowmelt potential. Mesoscale Model 5 and Ensemble Prediction System data are used as a main input and the flow forecasts are done for 2012 year using HEC-HMS. Hydrometeorological rule-based reservoir simulation model is accomplished with HEC-ResSim and integrated with forecasts. Since EPS based hydrological model produce a large number of equal probable scenarios, it will indicate how uncertainty spreads in the future. Thus, it will provide risk ranges in terms of spillway discharges and reservoir level for operator when it is compared with deterministic approach. The framework is fully data driven, applicable, useful to the profession and the knowledge can be transferred to other similar reservoir systems.

Performance Management for Faculty and Staff

This report examines the process used to evaluated faculty and staff, including the evaluation timeline, administrative oversight, technological tools, and performance management trainings for faculty and staff managers. Additionally, this report describes how administrators use annual performance evaluations to award merit-based pay.

Optimizing the Performance Evaluation Process for Non-Academic Staff

If conducted poorly and without support from all employee levels, performance management programs at institutions may devolve into annual evaluations that represent a staff burden rather than an ongoing career development opportunity. This brief analyzes the key components of successful performance evaluation systems for non-academic staff, incorporating insights from employers outside of the higher education sector as well. It examines the importance of midyear check-in meetings; employee goal-setting; simplified rating scales on evaluation forms; and core staff competencies that reflect institutional priorities. It also describes how institutions communicate modifications to the evaluation system and offers recommendations for the implementation of process change.

Informatiza����o da opera����o e da gest��o de uma unidade de sa��de de alta complexidade do sistema ��nico de sa��de (SUS): estudo de caso do instituto de medicina integral Prof. Fernando Figueira (Imip) sob o enfoque do isomorfismo institucional

O trabalho buscou identificar e avaliar a escolha do Imip �� luz da teoria neoinstitucional, mediante os mecanismos isom��rficos que caracterizam o campo das organiza����es de sa��de. Trata-se de um estudo de caso, tendo o Imip como objeto de an��lise, voltado especificamente para dois modelos de informatiza����o da opera����o e da gest��o, a fim de verificar qual o mais adequado para as especificidades da institui����o, incluindo o aspecto financeiro, custo/benef��cio. O primeiro modelo se refere a um sistema pr��prio de informatiza����o; o segundo a um modelo de sistema de gest��o j�� existente, comercializado por empresa especializada nesta tecnologia. A metodologia abrangeu pesquisas bibliogr��ficas, documentais e de campo. O referencial te��rico foi a teoria neoinstitucional e o trabalho de campo constou de uma pesquisa incluindo observa����o simples, visando compor vari��veis dos dois modelos avaliados, e coleta de dados realizada por meio da aplica����o de dois question��rios: um question��rio aberto, com os dirigentes do Imip, e um question��rio misto, com cem colaboradores, utilizadores do sistema, escolhidos aleatoriamente, por sorteio. Entre os achados se identificou claras refer��ncias ao isomorfismo, principalmente o mim��tico, nas percep����es dos indiv��duos respondentes. Ao final da pesquisa, foi poss��vel concluir que a contrata����o de um sistema de gest��o hospitalar, j�� existente no mercado, concebido e comercializado por empresa de tecnologia especializada no segmento da sa��de, justificou-se como a melhor escolha para a organiza����o, pois, as semelhan��as existentes entre os processos do Instituto e aqueles contidos no sistema eram muito mais relevantes que suas particularidades. Outro fator relevante levou em considera����o os elevados custos para uma ��nica institui����o desenvolver e manter sozinha um sistema atualizado segundo as exig��ncias normativas e t��cnicas necess��rias ��s organiza����es de sa��de e os padr��es de qualidade da informa����o estabelecidos pelo SUS.

Avalia����o do novo modelo de a����o fiscal de Secretaria da Fazenda do Estado de Pernambuco

N��o �� tarefa f��cil abordar um tema como o de tributos, principalmente em um pa��s como o Brasil, com grandes e hist��ricas d��vidas sociais, que permanece com uma das cargas tribut��rias mais elevadas do Mundo e com uma qualidade na oferta de servi��os p��blicos que, na maioria das vezes, deixa a desejar. Pior ainda �� discutir a efic��cia do papel do Auditor Fiscal, j�� que temos a miss��o de prover o Estado de recursos p��blicos para a implementa����o e manuten����o de pol��ticas necess��rias para a sociedade. Nem sempre para cumprir esse papel conta-se com o apoio integral da classe pol��tica e da popula����o. Para compensar tal desafio, a maior motiva����o e certeza �� que h�� na Secretaria da Fazenda do Estado de Pernambuco verdadeiros empreendedores com capacidade t��cnica e vontade de mudar algumas realidades, j�� n��o t��o sintonizadas com os desafios dos tempos modernos. Partindo da premissa que a introdu����o do Planejamento, por meio da cria����o da Diretoria de Planejamento e Controle da A����o Fiscal no in��cio de 2002 na estrutura organizacional da Administra����o Tribut��ria, resultou em um salto de qualidade no resultado da a����o fiscal, esse estudo apresenta uma avalia����o dos processos fiscais comparando-se a partir de 1998 at�� o in��cio de 2002 e da�� at�� o ano de 2006. Percebe-se que n��o houve incremento em rela����o �� efetividade da a����o fiscal, constatando-se correla����o estat��stica entre os valores recuperados pelo Fisco quando comparados o per��odo posterior �� mudan��a organizacional com o anterior, verificado pelo Teste de Wilcoxon. Ao mesmo tempo, percebeu-se uma necessidade clara do Estado rever suas leis, prazos e condi����es de trabalho no que se refere �� execu����o fiscal, sob pena de n��o conseguir reaver parcela de tributo sonegado em tempo h��bil, j�� que 84,9% dos processos n��o tiveram suas defesas administrativas apresentadas ou saldos devedores regularizados. Na pesquisa dirigida aos gerentes da Diretoria de Planejamento, suas respostas indicam que o caminho precisa ser mantido, buscando cont��nua evolu����o e coer��ncia do planejamento estrat��gico e permanente aperfei��oamento do modelo de gest��o adotado em busca de resultados, com sensibilidade social e respeito profissional a cada integrante do ��rg��o.
