Full Text Available School restructuring raises questions about the role of school districts in improving student learning. Centralization by state governments and decentralization to individual schools as proposed in systemic reform leave districts' role unsettled. Empirical research on the district role in the context of ongoing reform is inadequate. This analysis of combined data from the NAEP and the Common Core of Data (CCD was intended to address the issue. We analyzed 1990, 1992, and 1996 NAEP 8th grade mathematics national assessment data in combination with CCD data of corresponding years to examine the extent to which student achievement was related to districts' control over instructional expenditure, adjusting for relevant key factors at both district and student levels. Upon sample modification, we used hierarchical linear modeling (HLM to estimate the relationships of student achievement to two district fiscal policy indictors, current expenditure per pupil (CEPP and districts' discretionary rates for instructional expenditure (DDR. Net of relevant district factors, DDR was found unrelated to districts' average 8th grade math performance. The null effect was consistent in the analysis of the combined NAEP-CCD data for 1990, 1992, and 1996. In contrast, CEPP was found related to higher math performance in a modest yet fairly consistent way. Future research may be productive to separately study individual states and integrate the findings onto the national level.

Comparing the performance of cluster random sampling and integrated threshold mapping for targeting trachoma control, using computer simulation.

Full Text Available Implementation of trachoma control strategies requires reliable district-level estimates of trachomatous inflammation-follicular (TF, generally collected using the recommended gold-standard cluster randomized surveys (CRS. Integrated Threshold Mapping (ITM has been proposed as an integrated and cost-effective means of rapidly surveying trachoma in order to classify districts according to treatment thresholds. ITM differs from CRS in a number of important ways, including the use of a school-based sampling platform for children aged 1-9 and a different age distribution of participants. This study uses computerised sampling simulations to compare the performance of these survey designs and evaluate the impact of varying key parameters.Realistic pseudo gold standard data for 100 districts were generated that maintained the relative risk of disease between important sub-groups and incorporated empirical estimates of disease clustering at the household, village and district level. To simulate the different sampling approaches, 20 clusters were selected from each district, with individuals sampled according to the protocol for ITM and CRS. Results showed that ITM generally under-estimated the true prevalence of TF over a range of epidemiological settings and introduced more district misclassification according to treatment thresholds than did CRS. However, the extent of underestimation and resulting misclassification was found to be dependent on three main factors: (i the district prevalence of TF; (ii the relative risk of TF between enrolled and non-enrolled children within clusters; and (iii the enrollment rate in schools.Although in some contexts the two methodologies may be equivalent, ITM can introduce a bias-dependent shift as prevalence of TF increases, resulting in a greater risk of misclassification around treatment thresholds. In addition to strengthening the evidence base around choice of trachoma survey methodologies, this study illustrates

The single biggest barrier for countries in sub-Saharan Africa (SSA) to scale up the necessary health services for addressing the three health-related Millennium Development Goals and achieving Universal Health Coverage is the lack of an adequate and well-performing health workforce. This deficit needs to be addressed both by training more new health personnel and by improving the performance of the existing and future health workforce. However, efforts have mostly been focused on training new staff and less on improving the performance of the existing health workforce. The purpose of this paper is to disseminate the protocol for the PERFORM project and reflect on the key challenges encountered during the development of this methodology and how they are being overcome. The overall aim of the PERFORM project is to identify ways of strengthening district management in order to address health workforce inadequacies by improving health workforce performance in SSA. The study will take place in three districts each in Ghana, Tanzania and Uganda using an action research approach. With the support of the country research teams, the district health management teams (DHMTs) will lead on planning, implementation, observation, reflection and redefinition of the activities in the study. Taking into account the national and local human resource (HR) and health systems (HS) policies and practices already in place, 'bundles' of HR/HS strategies that are feasible within the context and affordable within the districts' budget will be developed by the DHMTs to strengthen priority areas of health workforce performance. A comparative analysis of the findings from the three districts in each country will add new knowledge on the effects of these HR/HS bundles on DHMT management and workforce performance and the impact of an action research approach on improving the effectiveness of the DHMTs in implementing these interventions. Different challenges were faced during the development of

This paper investigates the groundwater quality in six major districts of Madhya Pradesh in central India, namely, Balaghat, Chhindwara, Dhar, Jhabua, Mandla, and Seoni during the 2010-2011 sampling campaign, and discusses improvements made in the supplied water quality between the years 2011 and 2017. Groundwater is the main source of water for a combined rural population of over 7 million in these districts. Its contamination could have a huge impact on public health. We analyzed the data collected from a large-scale water sampling campaign carried out by the Public Health Engineering Department (PHED), Government of Madhya Pradesh between 2010 and 2011 during which all rural tube wells and dug wells were sampled in these six districts. Eight hundred thirty-one dug wells and 47,606 tube wells were sampled in total and were analyzed for turbidity, hardness, iron, nitrate, fluoride, chloride, and sulfate ion concentrations. Our study found water in 21 out of the 228 dug wells in Chhindwara district unfit for drinking due to fluoride contamination while all dug wells in Balaghat had fluoride within the permissible limit. Twenty-six of the 56 dug wells and 4825 of the 9390 tube wells in Dhar district exceeded the permissible limit for nitrate while 100% dug wells in Balaghat, Seoni, and Chhindwara had low levels of nitrate. Twenty-four of the 228 dug wells and 1669 of 6790 tube wells in Chhindwara had high iron concentration. The median pH value in both dug wells and tube wells varied between 6 and 8 in all six districts. Still, a significant number of tube wells exceeded a pH of 8.5 especially in Mandla and Seoni districts. In conclusion, this study shows that parts of inhabited rural Madhya Pradesh were potentially exposed to contaminated subsurface water during 2010-2011. The analysis has been correlated with rural health survey results wherever available to estimate the visible impact. We next highlight that the quality of drinking water has enormously improved

The aim of this study was to analyse the impact of sharing arrangement systems to performance of beef cattle breeding. This research was conducted in Kupang Regency - East Nusa Tenggara Province, Indonesia. The study used multi stage cluster random sampling method to determine the sample area and respondents. The sample areas consisted of 2 sub-districts and 6 villages, while the total respondents were 117 people comprised 74 Participant Farmers (PF) of sharing arrangement systems (SAS) and 43 non-participant farmers (NPF). 23 investors were selected for the survey. The result of the study indicated that the performance of NPF in terms of revenue, net profit, and return on investment (ROI) was better than PF respondents. The value of ROI was between 16.69-32.23 %. This indicated that utilization of farm asset was not optimum yet. It was found that farm efficiency was 1.73 which indicated that SAS does not increase farm productivity.

There is growing interest in health system performance and recently WHO launched a report on health systems strengthening emphasising the need for close monitoring using system-wide approaches. One recent method is the balanced scorecard system. There is limited application of this method in middle- and low-income countries. This paper applies the concept of balanced scorecard to describe the baseline status of three intervention districts in Zambia. The Better Health Outcome through Mentoring and Assessment (BHOMA) project is a randomised step-wedged community intervention that aims to strengthen the health system in three districts in the Republic of Zambia. To assess the baseline status of the participating districts we used a modified balanced scorecard approach following the domains highlighted in the MOH 2011 Strategic Plan. Differences in performance were noted by district and residence. Finance and service delivery domains performed poorly in all study districts. The proportion of the health workers receiving training in the past 12 months was lowest in Kafue (58%) and highest in Luangwa district (77%). Under service capacity, basic equipment and laboratory capacity scores showed major variation, with Kafue and Luangwa having lower scores when compared to Chongwe. The finance domain showed that Kafue and Chongwe had lower scores (44% and 47% respectively). Regression model showed that children's clinical observation scores were negatively correlated with drug availability (coeff -0.40, p = 0.02). Adult clinical observation scores were positively association with adult service satisfaction score (coeff 0.82, p = 0.04) and service readiness (coeff 0.54, p = 0.03). The study applied the balanced scorecard to describe the baseline status of 42 health facilities in three districts of Zambia.

Full Text Available Abstract Background There is a growing interest in using pay-for-performance mechanisms in low and middle-income countries in order to improve the performance of health care providers. However, at present there is a dearth of independent evaluations of such approaches which can guide understanding of their potential and risks in differing contexts. This article presents the results of an evaluation of a project managed by an international non-governmental organisation in one district of Pakistan. It aims to contribute to learning about the design and implementation of pay-for-performance systems and their impact on health worker motivation. Methods Quantitative analysis was conducted of health management information system (HMIS data, financial records, and project documents covering the period 2007-2010. Key informant interviews were carried out with stakeholders at all levels. At facility level, in-depth interviews were held, as were focus group discussions with staff and community members. Results The wider project in Battagram had contributed to rebuilding district health services at a cost of less than US$4.5 per capita and achieved growth in outputs. Staff, managers and clients were appreciative of the gains in availability and quality of services. However, the role that the performance-based incentive (PBI component played was less clear--PBI formed a relatively small component of pay, and did not increase in line with outputs. There was little evidence from interviews and data that the conditional element of the PBIs influenced behaviour. They were appreciated as a top-up to pay, but remained low in relative terms, and only slightly and indirectly related to individual performance. Moreover, they were implemented independently of the wider health system and presented a clear challenge for longer term integration and sustainability. Conclusions Challenges for performance-based pay approaches include the balance of rewarding individual

The soil is a complex mixture of different compounds and rocks. In the natural environment, it is an important source of exposure to radiation due to naturally occurring, gamma emitting radionuclides which include 226 Ra, 232 Th and 40 K present in the soil. The study of distribution of these radionuclides in soil and rock is of great importance for radiation protection and measurements. The activity concentrations of 226 Ra, 232 Th, and 40 K in soil and rock samples collected in Mandya District, Karnataka state, India have been measured by gamma ray spectrometry. The average activity concentrations of 226 Ra, 232 Th, and 40 K (Bq/kg) are found to be 40.2, 62.3, and 317.5 Bq/kg, respectively, in soil samples and 30.5, 34.4, and 700.2 Bq/kg, respectively, in rock samples. The concentrations of radionuclides in soil samples are found to higher than in rock samples. The concentrations of radionuclides in soil and rock samples in the study area are slightly higher than Indian average and world average values. (author)

Fugitive dust from 18 unsurfaced roadways in Missouri were sampled using a novel cyclonic fugitive dust collector that was designed to obtain suspended bulk samples for analysis. The samples were analyzed for trace metals, Fe and Al, particle sizes, and mineralogy to characterize the similarities and differences between roadways. Thirteen roads were located in the Viburnum Trend (VT) mining district, where there has been a history of contaminant metal loading of local soils; while the remaining five roads were located southwest of the VT district in a similar rural setting, but without any mining or industrial process that might contribute to trace metal enrichment. Comparison of these two groups shows that trace metal concentration is higher for dusts collected in the VT district. Lead is the dominant trace metal found in VT district dusts representing on average 79% of the total trace metal concentration, and was found moderately to strongly enriched relative to unsurfaced roads in the non-VT area. Fugitive road dust concentrations calculated for the VT area substantially exceed the 2008 Federal ambient air standard of 0.15μgm(-3) for Pb. The pattern of trace metal contamination in fugitive dust from VT district roads is similar to trace metal concentrations patterns observed for soils measured more than 40years ago indicating that Pb contamination in the region is persistent as a long-term soil contaminant.

Myrick, Melinda D.

2007-12-01

This study examined the extent to which human sexuality topics are covered in Florida middle school science classrooms and the process by which curricular decisions are made regarding human sexuality education on a county-wide basis. Primary data included interviews with county-level administrators who oversee curricular decisions related to the middle-grades science curriculum or health curriculum in twelve school districts within the state. These districts represented four geographic locations and districts of various sizes. Administrators from four of the twelve studies in the sample chose to provide information regarding their human sexuality education curriculum. In two cases, teacher leads were identified and were interviewed to understand the implementation of the curriculum within the classroom. Additional data were collected from the district curriculum guides for human sexuality education and the adopted middle-grades science textbook for each county. The interview and documentary data were analyzed by comparison to established criteria for a comprehensive human sexuality education curriculum. The analysis revealed that the scope of human sexuality education varied considerably within the sample and that much of the curricula in place failed to include topics and activities that have been identified as important in a successful human sexuality education program. These findings are limited because few counties chose to fully participate. Additional research is clearly needed to examine the effectiveness of existing human sexuality education curricula in Florida. In addition, research is needed to understand the characteristics, values, and beliefs of successful human sexuality education instructors across the state.

The optimal integration of booster heat pumps in ultra low temperature district heating (ULTDH) was investigated and compared to the performance of low temperature district heating. Two possible heat production technologies for the DH networks were analysed, namely extraction combined heat...... temperature and the heat consumption profile. For reference conditions, the optimal return of ULTDH varies between 21 °C and 27 °C. When using a central HP to supply the DH system, the resulting coefficient of system performance (COSP) was in the range of 3.9 (-) to 4.7 (-) for equipment with realistic...... component efficiencies and effectiveness, when including the relevant parameters such as DH system pressure and heat losses. By using ULTDH with booster HPs, performance improvements of 12% for the reference calculations case were found, if the system was supplied by central HPs. Opposite results were found...

In 2003, the Uganda Ministry of Health introduced the district league table for district health system performance assessment. The league table presents district performance against a number of input, process and output indicators and a composite index to rank districts. This study explores the use of hierarchical cluster analysis for analysing and presenting district health systems performance data and compares this approach with the use of the league table in Uganda. Ministry of Health and district plans and reports, and published documents were used to provide information on the development and utilization of the Uganda district league table. Quantitative data were accessed from the Ministry of Health databases. Statistical analysis using SPSS version 20 and hierarchical cluster analysis, utilizing Wards' method was used. The hierarchical cluster analysis was conducted on the basis of seven clusters determined for each year from 2003 to 2010, ranging from a cluster of good through moderate-to-poor performers. The characteristics and membership of clusters varied from year to year and were determined by the identity and magnitude of performance of the individual variables. Criticisms of the league table include: perceived unfairness, as it did not take into consideration district peculiarities; and being oversummarized and not adequately informative. Clustering organizes the many data points into clusters of similar entities according to an agreed set of indicators and can provide the beginning point for identifying factors behind the observed performance of districts. Although league table ranking emphasize summation and external control, clustering has the potential to encourage a formative, learning approach. More research is required to shed more light on factors behind observed performance of the different clusters. Other countries especially low-income countries that share many similarities with Uganda can learn from these experiences. © The Author 2015

To achieve Universal Health Coverage (UHC), more health workers are needed; also critical is supporting optimal performance of existing staff. Integrated human resource management (HRM) strategies, complemented by other health systems strategies, are needed to improve health workforce performance, which is possible at district level in decentralised contexts. To strengthen the capacity of district management teams to develop and implement workplans containing integrated strategies for workforce performance improvement, we introduced an action-research-based management strengthening intervention (MSI). This consisted of two workshops, follow-up by facilitators and meetings between participating districts. Although often used in the health sector, there is little evaluation of this approach in middle-income and low-income country contexts. The MSI was tested in three districts in Ghana, Tanzania and Uganda. This paper reports on the appropriateness of the MSI to the contexts and its effects. Documentary evidence (workshop reports, workplans, diaries, follow-up visit reports) was collected throughout the implementation of the MSI in each district and interviews (50) and focus-group discussions (6) were conducted with managers at the end of the MSI. The findings were analysed using Kirkpatrick's evaluation framework to identify effects at different levels. The MSI was appropriate to the needs and work patterns of District Health Management Teams (DHMTs) in all contexts. DHMT members improved management competencies for problem analysis, prioritisation and integrated HRM and health systems strategy development. They learnt how to refine plans as more information became available and the importance of monitoring implementation. The MSI produced changes in team behaviours and confidence. There were positive results regarding workforce performance or service delivery; these would increase with repetition of the MSI. The MSI is appropriate to the contexts where tested and

However, due to anthropogenic activities like indiscriminant use of arsenic in disinfectants, weedicides, medicines and fertilizers, arsenic toxicity is a severe environmental issue, both at national and global level. U.S. Environmental Protection Agency and World Health Organization prescribed the permissible limit of arsenic in drinking water to be 10 µg/l. Exposure to arsenic at higher levels over a considerable period of time leads to skin lesions and cancer, disorders of cardiovascular, respiratory, gastrointestinal, hepatic and renal systems. Murshidabad is one of the severely arsenic affected districts of West Bengal. We have analyzed soil and groundwater samples from some of the highly arsenic affected blocks of Murshidabad district. Both the soil and groundwater samples have an alkaline pH, a characteristic of the presence of arsenic in the tested samples. Unfortunately, the socio-economic conditions of these villages force the residents to use groundwater as the source of drinking water. Presence of considerably high amount of total dissolved solids in water samples make them further unfit for consumption. High amount of phosphate and iron present in some of the water samples takes a toll on the detoxification and excretory system of the body, if those water samples are consumed on a regular manner. Contamination of soil by the aforesaid contaminants results in biomagnification of these pollutants in the food chain. We could also isolate certain potentially arsenic resistant bacteria from the contaminated soil and water samples. At the next level we have surveyed an arsenic affected village to analyze the clinical manifestation of arsenic poisoning. In this village subjects developed rampant skin lesions throughout the body due to exposure to arsenic

Shortage of human resources is a major problem facing Malawi, where more than 50% of the population lives in rural areas. Most of the district health services are provided by clinical health officers specially trained to provide services that would normally be provided by fully qualified doctors or specialists. As this cadre and the cadre of enrolled nurses are the mainstay of the Malawian health service at the district level, it is important that they are supported and motivated to deliver a good standard of service to the population. This study explores how these cadres are managed and motivated and the impact this has on their performance. A quantitative survey measured health workers' job satisfaction, perceptions of the work environment and sense of justice in the workplace, and was reported elsewhere. It emerged that health workers were particularly dissatisfied with what they perceived as unfair access to continuous education and career advancement opportunities, as well as inadequate supervision. These issues and their contribution to demotivation, from the perspective of both management and health workers, were further explored by means of qualitative techniques.Focus group discussions were held with health workers, and key-informant interviews were conducted with members of district health management teams and human resource officers in the Ministry of Health. The focus groups used convenience sampling that included all the different cadres of health workers available and willing to participate on the day the research team visited the health facility. The interviews targeted district health management teams in three districts and the human resources personnel in the Ministry of Health, also sampling those who were available and agreed to participate. The results showed that health workers consider continuous education and career progression strategies to be inadequate.

Soltani, Reza; Dincer, Ibrahim; Rosen, Marc A.

2015-01-01

A Rankine cycle-driven heat pump system is modeled for district heating applications with superheated steam and hot water as products. Energy and exergy analyses are performed, followed by parametric studies to determine the effects of varying operating conditions and environmental parameters on the system performance. The district heating section is observed to be the most inefficient part of system, exhibiting a relative irreversibility of almost 65%, followed by the steam evaporator and the condenser, with relative irreversibilities of about 18% and 9%, respectively. The ambient temperature is observed to have a significant influence on the overall system exergy destruction. As the ambient temperature decreases, the system exergy efficiency increases. The electricity generated can increase the system exergy efficiency at the expense of a high refrigerant mass flow rate, mainly due to the fact that the available heat source is low quality waste heat. For instance, by adding 2 MW of excess electricity on top of the targeted 6 MW of product heat, the refrigerant mass flow rate increases from 12 kg/s (only heat) to 78 kg/s (heat and electricity), while the production of 8 MW of product heat (same total output, but in form of heat) requires a refrigerant mass flow rate of only 16 kg/s. - Highlights: • A new integrated heat pump system is developed for district heating applications. • An analysis and assessment study is undertaken through exergy analysis methodology. • A comparative efficiency evaluation is performed for practical applications. • A parametric study is conducted to investigate how varying operating conditions and state properties affect energy and exergy efficiencies.

2016-09-26

In early 1990s, Tanzania like other African countries, adopted health sector reform (HSR). The most strongly held centralisation system that informed the nature of services provision including health was, thus, disintegrated giving rise to decentralisation system. It was within the realm of HSR process, user fees were introduced in the health sector. Along with user fees, various types of health insurances, including the Community Health Fund (CHF), were introduced. While the country's level of enrolment in the CHF is low, there are marked variations among districts. This paper highlights the role of decentralised health management and leadership practices in the uptake of the CHF in Tanzania. A comparative exploratory case study of high and low performing districts was carried out. In-depth interviews were conducted with the members of the Council Health Service Board (CHSB), Council Health Management Team (CHMT), Health Facility Committees (HFCs), in-charges of health facilities, healthcare providers, and Community Development Officers (CDOs). Minutes of the meetings of the committees and district annual health plans and district annual implementation reports were also used to verify and triangulate the data. Thematic analysis was adopted to analyse the collected data. We employed both inductive and deductive (mixed coding) to arrive to the themes. There were no differences in the level of education and experience of the district health managers in the two study districts. Almost all district health managers responsible for the management of the CHF had attended some training on management and leadership. However, there were variations in the personal initiatives of the top-district health leaders, particularly the district health managers, the council health services board and local government officials. Similarly, there were differences in the supervision mechanisms, and incentives available for the health providers, HFCs and board members in the two study

Von Pressentin, Klaus B; Mash, Bob J; Esterhuizen, Tonya M

2017-04-28

The supply of appropriate health workers is a key building block in the World Health Organization's model of effective health systems. Primary care teams are stronger if they contain doctors with postgraduate training in family medicine. The contribution of such family physicians to the performance of primary care systems has not been evaluated in the African context. Family physicians with postgraduate training entered the South African district health system (DHS) from 2011. This study aimed to evaluate the impact of family physicians within the DHS of South Africa. The objectives were to evaluate the impact of an increase in family physician supply in each district (number per 10 000 population) on key health indicators. All 52 South African health districts were included as units of analysis. An ecological study evaluated the correlations between the supply of family physicians and routinely collected data on district performance for two time periods: 2010/2011 and 2014/2015. Five years after the introduction of the new generation of family physicians, this study showed no demonstrable correlation between family physician supply and improved health indicators from the macro-perspective of the district. The lack of a measurable impact at the level of the district is most likely because of the very low supply of family physicians in the public sector. Studies which evaluate impact closer to the family physician's circle of control may be better positioned to demonstrate a measurable impact in the short term.

Full Text Available The various problems in regional spatial planning in Waropen District Papua shows that the Spatial Planning RTRW of Waropen District Papua drafted in 2010 has not had a positive contribution to the settlement of spatial planning problems. This is most likely caused by the inconsistency in the spatial planning. This study tried to observe the consistency of spatial planning as well as its relation to the regional development performance. The method used to observe the consistency of the preparation of guided Spatial Planning RTRW is the analysis of comparative table followed by analysis of verbal logic. In order to determine if the preparation of Spatial Planning RTRW has already paid attention on the synergy with the surrounding regions Inter-Regional Context a map overlay was conducted followed by analysis of verbal logic. To determine the performance of the regional development a Principal Components Analysis PCA was done. The analysis results showed that inconsistencies in the spatial planning had caused a variety of problems that resulted in decreased performance of the regional development. The main problems that should receive more attention are infrastructure development growth economic growth transportation aspect and new properties.

Lyngkhoi, B.; Nongkynrih, P.

2018-04-01

The Activity Concentrations of naturally occurring radionuclides such as 40K, 238U and 232Th were determined from 20 (twenty) villages of East Khasi Hills District of Meghalaya, India using gamma-ray spectroscopy. This District is adjacent to the South-West Khasi Hills District located in the same state where heavy deposit of uranium has been identified [1]. The measured activities of 40K, 238U and 232Th were found ranging from 93.4 to 606.3, 23.2 to 140.9 and 25.1 to 158.9 Bq kg-1 with their average values of 207.9, 45.6 and 63.8 Bq kg-1, respectively. The obtained value of activity concentration for 40K is lower than the world average value 400.0 Bq kg-1 while for 238U and 232Th, the average concentrations are above the world average values 35.0 and 30.0 Bq kg-1, respectively. The calculated Absorbed Dose Rate gamma-radiation of the natural radionuclides ranged from 37.4 to 186.5 nGy h-1 with an average of 71.3 nGy h-1. The outdoor Annual Effective Dose Rate received by an individual ranged from 50.0-230.0 µSv y-1 with an average value of 87.5 µSv y-1. The physical and chemical properties of the soil have no effects on the naturally occurring radionuclides concentrations. This has been revealed by the results obtained as there is no positive correlation between physical/chemical parameters and the radionuclides concentrations in the soil samples [2]. It is observed that good positive correlations among the radionuclides concentrations and with the measured dose rate prevail. The findings show that the values of external and internal hazard indices resulting from the measured activity concentrations of natural radionuclides in soil from the collected sampling areas are less than the International Recommended safety limits of 1 (unity) with the exception of Mylliem (1.12) where the External hazard index is slightly higher.

Microbial diversity of soil and water samples collected from pyrochemicals exposed areas of Virdhunagar district (Tamil Nadu, India) was studied. Soil and water samples from cultivable area, waste land and city area of the same region were also studied for a comparative acount. There is a remarkable reduction in total heterotrophic bacterial population (THB) in pyrochemicals exposed soil and water samples (42 × 10(4) CFU/g and 5.6 × 10(4) CFU/ml respectively), compared to the THB of cultivable area soil and water samples (98 × 10(7) CFU/g and 38.6 × 10(7) CFU/ml). The generic composition the THB of the pyrochemicals exposed samples too exhibited considerable change compared to other samples. Pseudomonas sp. was the predominant one (41.6%) followed by Achromobacter sp. (25%) in pyrochemical exposed soil and Pseudomonas sp. was the predominant one (25%) in pyrochemical exposed water samples followed by Bacillus sp. (25%) and Micrococcus sp. (16.6%). It was observed that Cornybacterium sp. and Micrococcus sp. were absent completely in pyrochemical exposed soil and Achromobacter sp. was missing in the pyrochemical exposed water samples, which were present in the other samples. The outcome of this study clearly demonstrates that pollutants such as chemicals used in pyrotechniques affect the microbial biodiversity and suitable measures have to be taken to control the pollution level and to save biodiversity.

To assess the performance of the National Health Insurance Authority (NHIA) in Ghana. Using a thorough case study of the Juaboso District Office of the NHIA, this study assessed the community coverage rate, the annual expenditure and income, and the trend of claims payment for the period 2009 to 2012 as well as factors influencing the level of patronage of the National Health Insurance Scheme. A self-administered structured questionnaire was used to gather data from the management of the scheme. Secondary data were also gathered from the scheme's audited financial statements. Informal discussions were held with the premium collectors and clients to throw more light on revenue generation challenges. The study found an increasing trend in the coverage rate on a yearly basis. Over the study period, the rate moved from 30.6 to 60.1, representing an increase of 96.7%. This shows that in terms of coverage rate, the Juaboso District Office of the NHIA is performing very well. The study also found that revenue has increased but the percentage rate of increase has decreased, compared with the coverage percentage rate. Expenditure has been on the rise, increasing by as much as 20.7% in 2011. Again, the study revealed a consistent year-on-year increase in the claims payment, consistent with the national trend. Constant clinical auditing of claims payments is required to ensure accountability. This would lead to transparency with regard to performance assessment of the claims. The findings have important implications for the effective management of the NHIA. Copyright © 2016 International Society for Pharmacoeconomics and Outcomes Research (ISPOR).

Full Text Available Abstract Background The Nias district of the North Sumatra Province of Indonesia has long been known to be endemic for malaria. Following the economic crisis at the end of 1998 and the subsequent tsunami and earthquake, in December 2004 and March 2005, respectively, the malaria control programme in the area deteriorated. The present study aims to provide baseline data for the establishment of a suitable malaria control programme in the area and to analyse the frequency distribution of drug resistance alleles associated with resistance to chloroquine and sulphadoxine-pyrimethamine. Methods Malariometric and entomology surveys were performed in three subdistricts. Thin and thick blood smears were stained with Giemsa and examined under binocular light microscopy. Blood blots on filter paper were also prepared for isolation of parasite and host DNA to be used for molecular analysis of band 3 (SAO, pfcrt, pfmdr1, dhfr, and dhps. In addition, haemoglobin measurement was performed in the second and third surveys for the subjects less than 10 years old. Results Results of the three surveys revealed an average slide positivity rate of 8.13%, with a relatively higher rate in certain foci. Host genetic analysis, to identify the Band 3 deletion associated with Southeast Asian Ovalocytosis (SAO, revealed an overall frequency of 1.0% among the 1,484 samples examined. One hundred six Plasmodium falciparum isolates from three sub-districts were successfully analysed. Alleles of the dhfr and dhps genes associated with resistance to sulphadoxine-pyrimethamine, dhfr C59R and S108N, and dhps A437G and K540E, were present at frequencies of 52.2%, 82.5%, 1.18% and 1.18%, respectively. The pfmdr1 alleles N86Y and N1042D, putatively associated with mefloquine resistance, were present at 31.4% and 2%, respectively. All but one sample carried the pfcrt 76T allele associated with chloroquine resistance. Entomologic surveys identified three potential anopheline vectors in

Full Text Available Assessment of radioactive elements in the residential area is very important from different points of view especially for human health. The aim of present survey was focused on determining the current radon exhalation rate and radium concentration in soil samples collected from some areas of the Ganderbal district, Jammu and Kashmir, India. “Can technique” has been employed for the measurement of radon exhalation rate and radium concentration in soil samples collected from under study areas. The Uranium concentration in these soil samples where estimated by using the fission track registration technique (using LR-115 plastic track detectors.The uranium concentration was found to varies between 2.03 and 3.52 ppm. The radon exhalation rate in these samples has been found to vary from 5.05 to 21.89 m Bq kg−1 h−1. Radium concentration in soil samples varies from 6.43 to 18.89 Bq kg−1. The calculated values of Uranium concentration in these soil/rock samples are quite lower than the risk level. Radon and radium values found in these samples are also lower than that of optimum value. Hence these areas can be considered as risk free zones from human health point of view.

Full Text Available Background: One promising way to improve the motivation of healthcare providers and the quality of healthcare services is performance-based incentives (PBIs also referred as performance-based financing. Our study aims to explore healthcare providers’ preferences for an incentive scheme based on local resources, which aimed at improving the quality of maternal and child health care in the Nouna Health District. Design: A qualitative and quantitative survey was carried out in 2010 involving 94 healthcare providers within 34 health facilities. In addition, in-depth interviews involving a total of 33 key informants were conducted at health facility levels. Results: Overall, 85% of health workers were in favour of an incentive scheme based on the health district's own financial resources (95% CI: [71.91; 88.08]. Most health workers (95 and 96% expressed a preference for financial incentives (95% CI: [66.64; 85.36] and team-based incentives (95% CI: [67.78; 86.22], respectively. The suggested performance indicators were those linked to antenatal care services, prevention of mother-to-child human immunodeficiency virus transmission, neonatal care, and immunization. Conclusions: The early involvement of health workers and other stakeholders in designing an incentive scheme proved to be valuable. It ensured their effective participation in the process and overall acceptance of the scheme at the end. This study is an important contribution towards the designing of effective PBI schemes.

Iodine is an essential component of the hormones produced by the thyroid gland that are essential for mammalian life. Although goiter is the most visible sequelae of iodine deficiency, the major impact of hypothyroidism as a result of iodine deficiency is impaired neurodevelopment, particularly early in life. According to the World Health Organization, it is the single most preventable cause of mental retardation and brain damage. The simplest, most effective and inexpensive preventive method is the consumption of iodized salt. The objective of the following study is to estimate the prevalence of goiter in children in the rural areas of Mysore and Coorg districts in India and estimate iodine levels in salt samples. A cross-sectional study in the age group of 6-12 years, using population proportionate to size systematic sampling method. The total sample size was 10,082: out of which 5337 was from Mysore and the rest from Coorg district. Clinical examination of the thyroid gland was done and salt samples collected for the estimation of Iodine. The total prevalence of goiter was 19.01% in children of 6-12 years in Coorg district and 8.77% in Mysore district and it was more in females than in males. It was observed that iodine deficiency disorders is endemic in both districts, with a prevalence of 19.01% in children aged 6-12 years in Coorg district and 8.77% in Mysore district. Analysis of salt samples suggested that most of the samples were inadequately iodised (73.92% in Coorg and 45.92% in Mysore).

Nithra Kitreerawutiwong

Full Text Available Poor and middle-income Thai people rely heavily on primary care health services. These are staffed by a range of professionals. However, it is unknown whether the performance of primary care varies according to the staffing and organization of local service delivery units. Tambon (sub-district health promotion hospitals (THPHs were introduced in 2009 to upgrade the services offered by the previous health centres, but were faced with continuing shortages of doctors and nurses. The Ministry of Public Health (MoPH designated three categories of THPH, defined according to whether they were regularly staffed by a medical practitioner, a qualified nurse or non-clinical public health officers. This study aimed to compare the performance of primary care offered by the three different types of primary care facilities in one public health region of Northern Thailand (Public Health Region 2.A cross-sectional survey was undertaken in 2013. Data were collected on accessibility, continuity, comprehensiveness, co-ordination and community orientation of care from 825 patients attending 23 primary care facilities. These were selected to include the three officially-designated types of Tambon (sub-district health promotion hospitals (THPHs led by medical, nursing or public health personnel. Survey scores were compared in unadjusted and adjusted analyses.THPHs staffed only by public health officers achieved the highest performance score (Mean = 85.14, SD. = 7.30, followed by THPHs staffed by qualified nurses (Mean = 82.86, SD. = 7.06. THPHs staffed by a doctor on rotation returned the lowest scores (Mean = 81.63, SD. = 7.22.Differences in overall scores resulted mainly from differences in reported accessibility, continuity, and comprehensiveness of care, rather than staff skill-mix per se. Policy on quality improvement should therefore focus on improving performance in these areas.

Full Text Available Background: Visceral leishmaniasis (VL or kala-azar is a parasitic disease caused by the species of Leishmania donovani complex. Mediterranean type of the disease is endemic in some parts of Iran and more than 95% of cases were reported in children up to 12 years of age. This study was performed to determine the seroprevalence of VL in the rural areas of the Dashti district from Bushehr province.Materials and Methods: In this cross-sectional study, a randomized cluster sampling method was used for the collection of blood samples from children up to 12 years old from rural areas of Dashti district. Before sampling; a questionnaire was filled out for each case. All the collected blood samples were examined after the serum separating by Direct Agglutination Test (DAT for detection of anti-Leishmania infantum antibodies. The cutoff titers of ≥1: 3200 with specific clinical features were supposed to be considered as VL.Results: Altogether, 24 out of 1221 (1.96% blood samples showed titers between 1:800 and 1:1600 which considered as suspicious cases. None of the suspicious cases had a history of kala-azar. None of 1221 collected blood samples showed anti Leishmania infantum (L. infantum at titer ≥1:3200.Conclusion: This study confirms the circulation of L. infantum in Dashti district and highlights the sporadic pattern of VL in the studied areas which necessitates the surveillance system to be monitored by health authorities.

Uganda is vulnerable to several natural, man-made and a hybrid of disasters including drought, famine, floods, warfare, and disease outbreaks. We assessed the district disaster team's performance, roles and experiences following the training. The disasters most commonly experienced by the district teams were epidemics of diseases in humans (7 of 12), animals (epizoonotics) (3 of 12) and crops (3 of 12); hailstorms and floods (3 of 12). The capabilities viewed most useful for management of disasters were provision of health care services (9/12) and response management (8 of 12). The capability domains most often consulted during the disasters were general response management (31%), health services (29%) and water and sanitation (17%). The skills areas perceived to be vital following the training were response to epidemics 10/12, disaster management planning 8/12, hazards and vulnerability analysis 7/12 and principles of disaster planning 7/12 respectively. Main challenges mentioned by district teams were inadequacy of finance and logistics, lack of commitment by key partners towards disaster preparedness and response. The most common disaster experienced disasters related to outbreaks of diseases in man, animals and crops. The most frequently applied capabilities were response management and provision of emergency health services. The activities most frequently implemented following disaster management teams training were conducting planning meetings, refinement of plans and dissemination of skills gained. The main challenges were related to limited budget allocations and legal frameworks for disaster management that should be addressed by both central and local governments.

Botswana has a shortage of health care workers, especially in primary healthcare. Retention and high performance of employees are closely linked to job satisfaction and motivation, which are both highest where employees' personal values and goals are realised. The aim of the study was to evaluate employees' personal values, and the current and desired organisational culture of the district health services as experienced by the primary health care workers. The study was conducted in the Ngamiland and Mahalapye health districts. This was a cross sectional survey. The participants were asked to select 10 values that best described their personal, current organisational and desired organisational values from a predetermined list. Sixty and 67 health care workers completed the survey in Mahalapye and Ngamiland districts, respectively. The top 10 prevalent organisational values experienced in both districts were: teamwork, patient satisfaction, blame, confusion, job insecurity, not sharing information and manipulation. When all the current values were assessed, 32% (Mahalapye) and 36% (Ngamiland) selected by health care workers were potentially limiting organisational effectiveness. The organisational values desired by health care workers in both districts were: transparency, professional growth, staff recognition, shared decision-making, accountability, productivity, leadership development and teamwork. The experience of the primary health care workers in the two health districts were overwhelmingly negative, which is likely to contribute to low levels of motivation, job satisfaction, productivity and high attrition rates. There is therefore urgent need for organisational transformation with a focus on staff experience and leadership development.

The forests of Burdur district for long have been subjected to over grazing and individual selection. As a result of this, majority of the forest areas in the district were degraded. In the district, afforestation efforts included majority of forestry implementations. It is well known that selecting suitable species plays an important role for achieving afforestation efforts. In this context, knowing the indicator species among the target species would be used in afforestation efforts, studies on the interrelationships between environmental factors and target species distribution is vital for selecting suitable species for a given area. In this study, Anatolian Black pine (Pinus nigra), Red pine (Pinus brutia), Crimean juniper (Juniperus excelsa) and Taurus cedar (Cedrus libani), essential tree species, were considered as target species. The data taken from 100 sample plots in Burdur district was used. Interspecific correlation analysis was performed to determine the positive and negative indicator species among each of the target species. As a result of ICA, 2 positive (Berberis crataegina, Juniperus oxycedrus), 2 negative (Phillyrea latifolia, Quercus coccifera) for Crimean Juniper, I positive (Juniperus oxycedrus), 3 negative (Onopordium acanthium, Fraxinus ornus, Phillyrea latifolia) for Anatolian black pine, 3 positive (Paliurus spina-christi, Quercus coccifer, Crataegus orientalis), 2 negative (Berberis crataegina, Astragalus nanus) for Red pine and 3 positive (Berberis crataegina, Rhamnus oleoides, Astragalus prusianus) 2 negative (Paliurus spina-christi, Quercus cerris) for Taurus cedarwere defined as indicator plant species. In this way, practical information was obtained for selecting the most suitable species, among the target species, for afforestation efforts in Burdur district.

Automatic meter reading system is capable of collecting and storing a huge number of district heating (DH) data. However, the data obtained are rarely fully utilized. Data mining is a promising technology to discover potential interesting knowledge from vast data. This paper applies data mining methods to analyse the massive data for improving energy performance of DH substation. The technical approach contains three steps: data selection, cluster analysis and association rule mining (ARM). Two-heating-season data of a substation are used for case study. Cluster analysis identifies six distinct heating patterns based on the primary heat of the substation. ARM reveals that secondary pressure difference and secondary flow rate have a strong correlation. Using the discovered rules, a fault occurring in remote flow meter installed at secondary network is detected accurately. The application demonstrates that data mining techniques can effectively extrapolate potential useful knowledge to better understand substation operation strategies and improve substation energy performance.

Full Text Available Background: Botswana has a shortage of health care workers, especially in primary healthcare. Retention and high performance of employees are closely linked to job satisfaction and motivation, which are both highest where employees’ personal values and goals are realised. Aim: The aim of the study was to evaluate employees’ personal values, and the current and desired organisational culture of the district health services as experienced by the primary health care workers. Setting: The study was conducted in the Ngamiland and Mahalapye health districts. Method: This was a cross sectional survey. The participants were asked to select 10 values that best described their personal, current organisational and desired organisational values from a predetermined list. Results: Sixty and 67 health care workers completed the survey in Mahalapye and Ngamiland districts, respectively. The top 10 prevalent organisational values experienced in both districts were: teamwork, patient satisfaction, blame, confusion, job insecurity, not sharing information and manipulation. When all the current values were assessed, 32% (Mahalapye and 36% (Ngamiland selected by health care workers were potentially limiting organisational effectiveness. The organisational values desired by health care workers in both districts were: transparency, professional growth, staff recognition, shared decision-making, accountability, productivity, leadership development and teamwork. Conclusions: The experience of the primary health care workers in the two health districts were overwhelmingly negative, which is likely to contribute to low levels of motivation, job satisfaction, productivity and high attrition rates. There is therefore urgent need for organisational transformation with a focus on staff experience and leadership development.

2009-12-01

Full Text Available Drug is one of the essential elements in healthcare that should be effectively and efficiently managed. Following thedecentralization in 2001 in Indonesia, drug management has changed in district drug management units and also in District General Hospitals. Certainly this condition influences the sustainability of drug access in primary health care such as in Community Health Center and District General Hospital, especially in drug financing policy. A cross sectional descriptive study to obtain information on drug management in public healthcare in district had been carried out between July and December 2006 in 10 District Public Drug Management Units from 10 district health offices and 9 district general hospitals as samples. Data were collected by interviewing heads of Drug Section in District Health Offices and heads of Hospital Pharmacies using structured questionnaires and observing drug storage in District Drug Management Units, Community Health Centers, and Hospital Pharmacies. Results of the study show that drug planning in District Health Offices and General Hospitals did not meet the basic real need in some districts nor District Hospitals. The minimum health service standards had no been achieved yet. Furthermore, drug procurement, storage and recording as well as reporting was not good enough either, such as shown by the existence of expired drugs. Lead time for drug delivery to community health centers in some districts was longer than the average of lead time in the past 3 years.

The aim of this study was to assess the contribution of mid-level management and support practices to the overall performance of a district healthcare system. This case study was carried out in the North Kivu Province of the Democratic Republic of the Congo. It was based on analysis of (i) preventive and curative healthcare services and (ii) management and support practices provided from 2000 to 2008. In response to recurring sociopolitical unrest since 1992, the mid-level health system (provincial level) in North Kivu has strengthened management and support practices. The main goals have been to optimize allocation of interventions by external emergency organizations and integration of specialized program activities, to harmonize intervention techniques implemented by external partners, to standardize supervision of sanitary districts with regard to care provider skills, and to adapt strategic options defined by the Ministry of Health to the provincial level. Using this comprehensive approach, the performance of the North Kivu Province in terms of curative and preventive care has exceeded the national average since 2001. Between 2001 and 2008, use of curative services progressed from 0.36 to 0.50 new cases/capita/year. Positive results have also been recorded for infrastructure coverage, essential medicine stock, health information system, and emergency preparedness. Stronger mid-level management and support practices have improved care activities in the health district while protecting the population from unstructured interventions by emergency organizations or specialized programs. A comprehensive management approach has also improved the resilience of the district and increased its contribution to Millennium Development Goals.

This report summarizes the responses to a mail survey sent to superintendents and other administrators of public school districts. The survey was part of an evaluation project for the USDOE Institutional Conservation Program (ICP). The goal of the project is to identify the most successful energy conservation measures (equipment and activities) available to the institutional buildings sector. To accomplish this goal, four specific research objectives were defined: To determine the impact of the ICP grants program on fostering energy efficiency and saving energy; to determine key characteristics of institutional conservation efforts outside the federal program; To determine the technical, organizational, and Institutional conditions that create the opportunity for energy conservation measures (ECMS) to be most effective; and to identify key technology transfer opportunities. This report focuses on those characteristics of school districts (and the schools within those districts) that might influence the identification, implementation, operation, and impacts of institutional energy conservation efforts. Information about institutional characteristics was gathered through a mail survey of public school districts and private schools. The first mailing resulted in responses from 90 of the 823 public school districts selected through a combination cluster-and-stratification sampling technique and 64 of the 1,700 private schools selected as a stratified random sample. Remaining project resources were used to collect data to achieve a statistically sound sample of a total of 250 public school districts by telephone interviews. In doing so, some questions had to be dropped. Responses from both the mall surveys and the telephone interviews of public school districts were combined into one data set. This report describes results for all 250 districts.

Performance of local information-based link prediction: a sampling perspective

Zhao, Jichang; Feng, Xu; Dong, Li; Liang, Xiao; Xu, Ke

2012-08-01

Link prediction is pervasively employed to uncover the missing links in the snapshots of real-world networks, which are usually obtained through different kinds of sampling methods. In the previous literature, in order to evaluate the performance of the prediction, known edges in the sampled snapshot are divided into the training set and the probe set randomly, without considering the underlying sampling approaches. However, different sampling methods might lead to different missing links, especially for the biased ways. For this reason, random partition-based evaluation of performance is no longer convincing if we take the sampling method into account. In this paper, we try to re-evaluate the performance of local information-based link predictions through sampling method governed division of the training set and the probe set. It is interesting that we find that for different sampling methods, each prediction approach performs unevenly. Moreover, most of these predictions perform weakly when the sampling method is biased, which indicates that the performance of these methods might have been overestimated in the prior works.

Teachers' Coping Strategies for Teaching Science in a ``Low-Performing'' School District

Science.gov (United States)

Moore, Felicia M.

2007-10-01

This study describes how teachers use their personal knowledge of a school district and their students to cope with teaching under stressful situations associated with economic, social, and institutional factors. The 3 teachers dealt with these issues in unique ways, focusing on helping students to overcome negative perceptions, value the importance of an education, and build strong relationships. A model of multicultural science professional development is proposed that complements the strengths that these teachers have. A task for science educators working with teachers and administration in schools and districts that are “critically low performing” is to support everyone in implementing pedagogical methods aimed at empowerment, social justice, and high achievement for all students.

Predicting sample size required for classification performance

Figueroa Rosa L

2012-02-01

Full Text Available Abstract Background Supervised learning methods need annotated data in order to generate efficient models. Annotated data, however, is a relatively scarce resource and can be expensive to obtain. For both passive and active learning methods, there is a need to estimate the size of the annotated sample required to reach a performance target. Methods We designed and implemented a method that fits an inverse power law model to points of a given learning curve created using a small annotated training set. Fitting is carried out using nonlinear weighted least squares optimization. The fitted model is then used to predict the classifier's performance and confidence interval for larger sample sizes. For evaluation, the nonlinear weighted curve fitting method was applied to a set of learning curves generated using clinical text and waveform classification tasks with active and passive sampling methods, and predictions were validated using standard goodness of fit measures. As control we used an un-weighted fitting method. Results A total of 568 models were fitted and the model predictions were compared with the observed performances. Depending on the data set and sampling method, it took between 80 to 560 annotated samples to achieve mean average and root mean squared error below 0.01. Results also show that our weighted fitting method outperformed the baseline un-weighted method (p Conclusions This paper describes a simple and effective sample size prediction algorithm that conducts weighted fitting of learning curves. The algorithm outperformed an un-weighted algorithm described in previous literature. It can help researchers determine annotation sample size for supervised machine learning.

District heating in Switzerland

International Nuclear Information System (INIS)

Herzog, F.

1991-01-01

District heating has been used in Switzerland for more than 50 years. Its share of the heat market is less than 3% today. An analysis of the use of district heating in various European countries shows that a high share of district heating in the heat market is always dependent on ideal conditions for its use. Market prospects and possible future developments in the use of district heating in Switzerland are described in this paper. The main Swiss producers and distributors of district heating are members of the Association of District Heating Producers and Distributors. This association supports the installation of district heating facilities where ecological, energetical and economic aspects indicate that district heating would be a good solution.

This study aims to develop assessment indicators of health education and promotion for non-communicable disease (NCD) demonstration districts in China and to identify significant factors associated with NCD health education and promotion work. Three complementary techniques were used to conduct this study in Hunan Province, China, between late 2013 and 2015. The Delphi technique was used to develop weighted assessment indicators, followed by the rank sum ratio (RSR) to normalise the weights through rank conversion. Lastly, the technique for order of preference by similarity to ideal solution was conducted to assess five randomly selected NCD demonstration districts representing five different orientations in the province. A total of 24 assessment indicators were constructed covering the following sections: organisational management, fund support, personnel supplies, health education and promotion, people's awareness of NCDs, management and control of patients with NCD, satisfaction with health education and promotion and health literacy of residents. Five districts were selected as samples for evaluation (Furong District, Ziyang District, Shaodong County, Shuangfeng County and Luxi County). Performance varied among the sites, with Furong District greatly surpassing the other sites, especially in fund support, media promotion, technical support for publicity materials, community promotion and supportive environment supplies. The latter four factors were also much greater in the second-ranked Luxi County site than those in the other sites (except Furong District). There were gaps in health education and promotion work in NCD demonstration districts in Hunan Province. The districts that performed better had obvious advantages in fund support, media promotion, technical support, community promotion and supportive environment supplies. Our study provided both a methodological reference and an assessment indicator framework for similar future studies. © Article author

In the present investigation, radon concentration and heavy metal analysis were carried out in drinking water samples in Jammu district, Jammu and Kashmir, India. The radon concentration was measured by using RAD-7, portable alpha particle detector. The values of radon concentration in drinking water samples were also compared within the safe limit recommended by different health agencies. The total annual effective dose ranged from 53.04 to 197.29 μSv y -1 . The annual effective dose from few locations from the studied area was found to be greater than the safe limit (100 μSv y -1 ) suggested by World Health Organisation (WHO) and EU Council. Heavy metal concentration was determined by atomic absorption spectrophotometer. A total of eight elements were analysed, viz. arsenic, mercury, zinc, iron, copper, chromium, manganese and cadmium. Heavy metals are considered to be the major pollutants of water sources. The results were compared with the limits of WHO, EU and Indian organisations. The trace metal analysis is not on the exceeding side of the permissible limit in all the samples. (authors)

The continuous generation of inert helium gas from uranium and its daughter products provides a potentially useful means for remote detection of uranium deposits. The practicality of conducting helium surveys in the atmosphere, soil gas, and ground water to explore for buried uranium deposits has been tested in the Grants district and in the Powder River Basin of Wyoming. No detectable helium anomalies related to buried or surface uranium deposits were found in the atmosphere. However, reproducible helium-in-soil-gas anomalies were detected spatially related to uranium deposits buried from 50 to 800 ft deep. Diurnal and atmospheric effects can cause helium content variations (noise) in soil gas that are as great as the anomalies observed from instantaneous soil-gas samples. Cumulative soil-gas helium analyses, such as those obtained from collecting undisturbed soil samples and degassing them in the laboratory, may reveal anomalies from 5 to 100 percent above background. Ground water samples from the Grants district, New Mexico, and the Powder River Basin, Wyoming, have distinctly anomalous helium values spatially related to buried uranium deposits. In the southern Powder River Basin, helium values 20 to 200 percent above background occur 2 to 18 mile down the ground-water flow path from known uranium roll-front deposits. In the Grants district, helium contents 40 to 700 percent above background levels are present in ground waters from the host sandstone in the vicinity of uranium deposits and from aquifers up to 3,000 ft stratigraphically above the deep uranium deposits. The use of helium in soil and ground-water surveys, along with uranium and radon analyses of the same materials, is strongly recommended is expensive, deep, uranium-exploration programs such as those being conducted in the Grants district

The National Socio-Economic Survey samples are designed to produce estimates of parameters of planned domains (provinces and districts). The estimation of unplanned domains (sub-districts and villages) has its limitation to obtain reliable direct estimates. One of the possible solutions to overcome this problem is employing small area estimation techniques. The popular choice of small area estimation is based on linear mixed models. However, such models need strong distributional assumptions and do not easy allow for outlier-robust estimation. As an alternative approach for this purpose, M-quantile regression approach to small area estimation based on modeling specific M-quantile coefficients of conditional distribution of study variable given auxiliary covariates. It obtained outlier-robust estimation from influence function of M-estimator type and also no need strong distributional assumptions. In this paper, the aim of study is to estimate the poverty indicator at sub-district level in Bogor District-West Java using M-quantile models for small area estimation. Using data taken from National Socioeconomic Survey and Villages Potential Statistics, the results provide a detailed description of pattern of incidence and intensity of poverty within Bogor district. We also compare the results with direct estimates. The results showed the framework may be preferable when direct estimate having no incidence of poverty at all in the small area.

Schools are in a unique position to meet the mental and behavioral health needs of children and adolescents because approximately 95% of young people aged 7-17 years attend school. Little is known, however, about policies related to counseling, psychological, and social services staffing in school districts. This study analyzed the prevalence of such policies in public school districts in the U.S. Data from four cycles (2000, 2006, 2012, and 2016) of the School Health Policies and Practices Study, a national survey periodically conducted to assess policies and practices for ten components of school health, were analyzed in 2017. The survey collected data related to counseling, psychological, and social services among nationally representative samples of school districts using online or mailed questionnaires. Sampled districts identified respondents responsible for or most knowledgeable about the content of each questionnaire. The percentage of districts with a district-level counseling, psychological, and social services coordinator increased significantly from 62.6% in 2000 to 79.5% in 2016. In 2016, 56.3% of districts required each school to have someone to coordinate counseling, psychological, and social services at the school. Fewer districts required schools at each level to have a specified ratio of counselors to students (16.2% for elementary schools, 16.8% for middle schools, and 19.8% for high schools), and the percentage of districts with these requirements has decreased significantly since 2012. Increases in the prevalence of district-level staffing policies could help increase the quantity and quality of counseling, psychological, and social services staff in schools nationwide, which in turn could improve mental and behavioral health outcomes for students.

The use of food as a reward for good student behavior or academic performance is discouraged by many national organizations, yet this practice continues to occur in schools. Our multiyear cross-sectional study examined the use of food as a reward in elementary schools and evaluated the association between district policies and school practices. School data were gathered during the 2007-2008, 2008-2009, and 2009-2010 school years via mail-back surveys (N=2,069) from respondents at nationally representative samples of US public elementary schools (1,525 unique schools, 544 of which also participated for a second year). During every year, the corresponding district policy for each school was gathered and coded for provisions pertaining to the use of food as a reward. School practices did not change over time and as of the 2009-2010 school year, respondents in 42.1% and 40.7% of schools, respectively, indicated that food was not used as a reward for academic performance or for good student behavior. In multivariate logistic regression analyses controlling for school characteristics and year, having a district policy that prohibited the use of food as a reward was significantly associated with school respondents reporting that food was not used as a reward for academic performance (Preward than were respondents in the South and Northeast. As of 2009-2010, only 11.9% of the districts in our study prohibited the use of food as a reward. Strengthening district policies may reduce the use of food rewards in elementary schools.

Enteric parasites are the most common cause of parasitic diseases and cause significant morbidity and mortality, particularly in developing countries like Nepal. The objective of this study was to estimate the prevalence and risk factors of intestinal parasitic infections among school going children of Lalitpur district of Nepal. A total of 1392 stool samples were collected from school children of two government, two private and two community schools of the same district. The stool samples were examined for evidence of parasitic infections by direct microscopy and confirmed by concentration methods (formal ether sedimentation technique or floatation technique by using Sheather's sugar solution). Modified Ziehl-Neelsen (ZN) staining was performed for the detection of coccidian parasites. Prevalence of intestinal parasitosis was found to be 16.7%. The highest prevalence rate was seen with Giardia lamblia (7.4%) followed by Entamoeba histolytica (3.4%) and Cyclospora cayetanensis (1.6%). Children aged 11-15 years and the ones belonging to family of agriculture workers were most commonly affected. Hand washing practice and type of drinking water also showed significant difference. The burden of parasitic infections among the school children, coupled with the poor sanitary conditions in the schools, should be regarded as an issue of public health priority and demands for effective school health programs involving periodic health education and screening.

2004-01-01

Background: To eliminate Iodine Deficiency Disorders, (IDD) universal salt iodization is the widely practiced intervention. District Swat (a hilly area of NWFP, highly endemic for IDDs is selected as a first model district of the province for salt iodization program. Objectives: To find out the proportion of the families using iodized salt, iodine contents of the salts used by the families, urinary iodine levels in school children and the effect on goiter prevalence in Swat selected as a model district in 1998. Subject and Methods: The study was conducted in 960 children of both sexes, age 8-10 years in primary schools of district Swat in the year 2000. A replicate model used for base line study in 1998 was adopted. The students were clinically examined for goiter using palpation method. 960 edible salt samples for its iodine content and 240 urine samples for iodine level were analysed. Results: The overall goiter prevalence was found to be 52 and 45% in boys and girls respectively. 23% salt samples were found un-iodized, while in 25.6% the iodine content was less than 7ppm. The results revealed 18% decrease in total goiter rate and 35% increase in the use of iodized salt from the base line survey conducted in 1998, in school children of district Swat. Conclusions: The study revealed that since the area of Swat is still highly endemic for Iodine Deficiency Disorders, sustained efforts are required to ensure 100% salt iodization. (author)

More than seventy district heating (DH) plants based on biomass are operating in South Tyrol (Italy) and most of them supply heat to residential districts. Almost 20% of them are cogenerative systems, thus enabling primary energy savings with respect to the separate production of heat and power. However, the actual performance of these systems in real operation can considerably differ from the nominal one. The main objectives of this work are the assessment of the energy performance of a biomass boiler coupled with an Organic Rankine Cycle (i.e. ORC) generator under real operating conditions and the identification of its potential improvements. The fluxes of energy and mass of the plant have been measured onsite. This experimental evaluation has been supplemented with a thermodynamic model of the ORC generator, calibrated with the experimental data, which is capable to predict the system performance under different management strategies of the system. The results have highlighted that a decrease of the DH network temperature of 10 °C can improve the electric efficiency of the ORC generator of one percentage point. Moreover, a DH temperature reduction could decrease the main losses of the boiler, namely the exhaust latent thermal loss and the exhaust sensible thermal loss, which account for 9% and 16% of the boiler input power, respectively. The analysis of the plant has pointed out that the ORC pump, the flue gases extractor, the thermal oil pump and the condensation section fan are the main responsible of the electric self-consumption. Finally, the negative effect of the subsidisation on the performance of the plant has been discussed. - Highlights: • Energy performance of a biomass boiler coupled to an ORC turbine in real operation. • Potential improvements of a CHP plant connected to a DH network. • Performance prediction by means of a calibrated ORC thermodynamic model. • Influence of the DH temperature on the electric efficiency. • Impact of the

Full Text Available Coffee (Coffea spp is an important and emerging cash crop having potential to provide farmers employment and income generation opportunities. This crop is well adapted to the climatic conditions of mid-hills of Nepal. Thus, majority of the farmers are attracted towards cultivation of coffee because of demands in national and international market. Coffee is now becoming integral part of farming system in rural areas. However, information on performance of coffee and farmers response has not been well documented. Therefore, we undertook the present work to analyze demography, ethnicity, household occupation, literacy status, average land holding, coffee cultivation area, livelihood and sources of income of coffee growers, production and productivity, pricing, cropping pattern of the coffee and problesm faced by them in mid hill district of Kavrepalanchowk (hereafter ‘Kavre’ and Lalitpur Districts. All the samples were taken randomly and selected from coffee producing cooperative of Kavre and Lalitpur. Our analysis showed that the male farmer dominant over female on adopting coffee cultivation in both districts with higher value in Kavre. Brahmin and Chetri ethnic communities were in majority over others in adopting the coffee cultivation. Literate farmers were more dominant over illiterates on adopting the coffee cultivation, The mean land holding was less, ranging from 0.15 to 2.30 ha for coffee cultivation, the history of coffee cultivation in Kavre showed that highest number of farmers were engaged in coffee farming from last 16 years. The mean yield of fresh cherry was 1027.20 kg/ha in Kavre, while it was 1849.36 kg/ha in Lalitpur. The study revealed that majority of the coffee plantations were between 6-10 years old. The major problems facing by coffee farmers were diseases spread, lack of irrigation facility and drying of plants.

District nursing services in Northern Ireland face increasing demands and challenges which may be responded to by effective and efficient workforce planning and development. The aim of this paper is to critically analyse district nursing workforce planning and development methods, in an attempt to find a suitable method for Northern Ireland. A systematic analysis of the literature reveals four methods: professional judgement; population-based health needs; caseload analysis and dependency-acuity. Each method has strengths and weaknesses. Professional judgement offers a 'belt and braces' approach but lacks sensitivity to fluctuating patient numbers. Population-based health needs methods develop staffing algorithms that reflect deprivation and geographical spread, but are poorly understood by district nurses. Caseload analysis promotes equitable workloads but poorly performing district nursing localities may continue if benchmarking processes only consider local data. Dependency-acuity methods provide a means of equalizing and prioritizing workload but are prone to district nurses overstating factors in patient dependency or understating carers' capability. In summary a mixed method approach is advocated to evaluate and adjust the size and mix of district nursing teams using empirically determined patient dependency and activity-based variables based on the population's health needs.

Full Text Available In order to scientifically and reasonably evaluate water use efficiency and benefits in irrigation districts, a variable fuzzy assessment model was established. The model can reasonably determine the relative membership degree and relative membership function of the sample indices in each index's standard interval, and obtain the evaluation level of the sample through the change of model parameters. According to the actual situation of the Beitun Irrigation District, which is located in Fuhai County, in Altay City, Xinjiang Uyghur Autonomous Region, five indices were selected as evaluation factors, including the canal water utilization coefficient, field water utilization coefficient, crop water productivity, effective irrigation rate in farmland, and water-saving irrigation area ratio. The water use efficiency and benefits in the Beitun Irrigation District in different years were evaluated with the model. The results showed that the comprehensive evaluation indices from 2006 to 2008 were all at the third level (medium efficiency, while the index in 2009 increased slightly, falling between the second level (relatively high efficiency and third level, indicating an improvement in the water use efficiency and benefits in the Beitun Irrigation District, which in turn showed that the model was reliable and easy to use. This model can be used to assess the water use efficiency and benefits in similar irrigation districts.

Arsenic concentration in 13 well waters, 9 pond waters, 10 agricultural waters and a coconut juice taken in Comilla district, Bangladesh, where the problem of arsenic pollution is the most severe, was investigated. High-level arsenic is detected even in the well water which has been kept drinking by the people. Relatively high arsenic concentration was detected for some pond and farm waters even though the sampling was performed just after the rainy season and the waters were expected to be highly diluted. Clear relationship was observed in elemental compositions between the pond water and the coconut juice collected at the edge of the water. These results are expected to become the basic information for evaluating the risk of individual food such as cultured fishes, shrimps and farm products, and for controlling total intakes of arsenic. In order to solve the problem of transportation of water samples internationally, a simple method of target preparation performed at the sampling site was established and its validity was confirmed. All targets were prepared at the sampling sites in this study on the basis of this method. (author)

Full Text Available Assessment of natural radioactivity is very important from different points of view, especially for assessment of radiation exposure to human. In the present study, natural radionuclide concentrations of 238U, 232Th, and 40K were measured by gamma spectrometry using HPGe detector in soil samples collected from Southwest coast of Kanyakumari district, Tamil Nadu. The radiological index parameters due to natural radionuclides such as radium equivalent activity, absorbed dose rate, annual effective dose rate, external hazard index, internal hazard index, and gamma index were calculated for the soil samples. All the calculated radiological index values are higher than world average values and the recommended safety limits. Multivariate statistical techniques such as Pearson correlation, principal component analysis, and cluster analysis were applied to know the relation between radionuclides and radiological parameters and to study the spatial distribution of radionuclides.

Water supply network district metering theory and case study

CERN Document Server

Di Nardo, Armando; Di Mauro, Anna

2013-01-01

The management of a water supply network can be substantially improved defining permanent sectors or districts that enhances simpler water loss detection and pressure management. However, the water network partitioning may compromise water system performance, since some pipes are usually closed to delimit districts in order not to have too many metering stations, to decrease costs and simplify water balance. This may reduce the reliability of the whole system and not guarantee the delivery of water at the different network nodes. In practical applications, the design of districts or sectors is generally based on empirical approaches or on limited field experiences. The book proposes a design support methodology, based on graph theory principles and tested on real case study. The described methodology can help water utilities, professionals and researchers to define the optimal districts or sectors of a water supply network.

Performance assessment of a novel hybrid district energy system

International Nuclear Information System (INIS)

Coskun, C.; Oktay, Z.; Dincer, I.

2012-01-01

In this paper, a new hybrid system for improving the efficiency of geothermal district heating systems (GDHSs) is proposed. This hybrid system consists of biogas based electricity production and a water-to-water geothermal heat pump unit (GHPU), which uses the waste heat for both heating and domestic hot water purposes. Electricity generated by the biogas plant (BP) is utilized to drive the GDHS's pumps, BP systems and the heat pump units. Both the biogas reactor heating unit and the heat pump unit utilize the waste heat from the GDHS and use the system as a heat source. The feasibility of utilizing a hybrid system in order to increase the overall system (GDHS + BP + GHPU) efficiency is then investigated for possible efficiency improvements. The Edremit GDHS in Turkey, which is selected for investigation in this case study, reinjects 16.8 MW of thermal power into the river at a low temperature; namely at 40 °C. Such a temperature is ideal for mesophilic bacterial growth in the digestion process during biogas production. 1.45 MW of biogas based electricity production potential is obtainable from the waste heat output of the Edremit GDHS. The average overall system efficiencies through the utilization of this kind of hybridized system approach are increased by 7.5% energetically and 13% for exergetically. - Highlights: ► A new hybrid system is proposed for improving the efficiency of geothermal district heating systems (GDHSs). ► The average overall system efficiencies are increased by 7.5% for energy and 13% for exergy, respectively. ► Various energetic and exergetic parameters are studied.

Today, sustainable energy development is one of key issues on European development agenda. The article describes one of sustainable energy development promoting tool - the eco-labelling scheme for district heating and cooling systems elaborated within the framework of Intelligent Energy for Europe program project “Ecoheat4cities” and partially funded by European Agency for Competitiveness and Innovation. The scheme is based on measured energy and environmental performance data of the district heating and cooling system and considers primary non-renewable energy usage together with the share of renewable energy and carbon dioxide emissions calculated using life-cycle analysis methodology. The “power bonus” approach is used for performance indicators of the heat generated in cogeneration installations. An analysis of a number of Lithuanian district heating companies using elaborated labelling criteria shows positive trends towards fulfilling Lithuania's energy policy goals. The labelling scheme gives opportunity for policy makers and urban planners to compare different heat supply options and decide upon exploiting district heating advantages and benefits for reaching EU energy and environment policy goals. - Highlights: • Overview of Lithuania's district heating sector was performed via main sustainability criteria. • Developing to greener and more efficient state was disclosed via analysis of three years activity results. • Green labelling may help district heating companies to maintain existing and attract new potential consumers.

To examine the influence of state laws and district policies on district-wide elementary school and middle school practices related to physical education (PE) time and the percentage of moderate-to-vigorous physical activity (MVPA) time during PE. Multivariate, cross-sectional analysis of state laws, district wellness and PE policies, and district PE practices for school year 2010-2011 controlling for district-level urbanicity, region, size, race/ethnicity of students, and socioeconomic status and clustered on state. One hundred ninety-five public school districts located in 42 states. District-level PE coordinators for the included districts who responded to an online survey. Minutes and days of PE per week and percent time spent in MVPA during PE time. District PE coordinators reported significantly less PE time than national standards-82.9 and 189.6 minutes at the elementary school and middle school levels, respectively. Physical education was provided an average of 2.5 and 3.7 days per week, respectively; and the percentage of MVPA time in PE was 64.4% and 65.7%, respectively. At the elementary school level, districts in either states with laws governing PE time or in a state and district with a law/policy reported significantly more days of PE (0.63 and 0.67 additional days, respectively), and districts in states with PE time laws reported 18 more minutes of PE per week. At the middle school level, state laws were associated with 0.73 more days of PE per week. Neither state laws nor district policies were positively associated with percent MVPA time in PE. State laws and district policies can influence district-level PE practices-particularly those governing the frequency and duration of PE-although opportunities exist to strengthen PE-related laws, policies, and practices.

This report describes reconnaissance hydrogeochemical investigations of 22 mining districts on the Western Slope of Colorado in the Gunnison and Uncompahgre National Forests and adjacent public lands administered by the Bureau of Land Management. Sources and fates of contaminants from historic mines, mine waste, and mill tailings are interpreted from chemical analyses for 190 samples of surface waters; 185 samples of mined rocks, mill tailings, and altered rocks; and passive leach analyses of 116 samples of those mineralized materials. Short reaches of several headwater streams show relatively low level effects of historic mining; the headwaters of the Uncompahgre River are highly contaminated by mines and unmined altered rocks in the Red Mountain district. There is encouraging evidence that natural processes attenuate mine-related contamination in most districts.

Taber, Daniel R; Chriqui, Jamie F; Chaloupka, Frank J

2011-10-01

States and school districts nationwide have enacted policies targeting youth obesity, but many policies lack specific requirements or enforcement language. Geographic disparities in youth obesity could worsen if policies are weaker in areas with higher obesity prevalence. To determine if state or district policy strength varies with youth obesity prevalence across Census divisions. Policies in five domains related to nutrition and physical activity in schools were obtained from all states and nationally representative samples of 578 and 592 public school districts in the 2006-2007 and 2008-2009 school years, respectively. Policy language strength was rated on a 0-100 scale on both the state and district level. Regression models were used to determine if mean 2006-2007 strength scores, and changes in mean scores from 2006-2007 to 2008-2009, were associated with youth obesity prevalence across Census divisions. Analyses were conducted in 2010. State and district policies governing foods sold outside of school meal programs ("competitive foods") were stronger in 2006-2007 in the two divisions with the highest youth obesity prevalence (East South Central, West South Central). Furthermore, mean competitive food policy strength increased the most from 2006-2007 to 2008-2009 in these divisions. The West South Central had the weakest district physical education policies in 2006-2007, however, and was the only division in which average strength of district school meal policies decreased. State and districts in Census divisions with the highest youth obesity prevalence are taking steps to restrict competitive foods in schools, but many have not targeted other policy domains as aggressively.

Full Text Available In Africa, onchocerciasis and lymphatic filariasis (LF are co-endemic in many areas. Current efforts to eliminate both diseases are through ivermectin-based mass drug administration (MDA. Years of ivermectin distribution for onchocerciasis may have interrupted LF transmission in certain areas. The Kédougou region, Senegal, is co-endemic for LF and onchocerciasis. Though MDA for onchocerciasis started in 1988, in 2014 albendazole had not yet been added for LF. The objective of this study was to assess in an integrated manner the LF and onchocerciasis status in the three districts of the Kédougou region after ≥10 years of ivermectin-based MDA. The study employed an African Programme for Onchocerciasis Control (APOC onchocerciasis-related methodology. In the three districts, 14 villages close to three rivers that have Simulium damnosum breeding sites were surveyed. Convenience sampling of residents ≥5 years old was performed. Assessment for LF antigenemia by immunochromatographic testing (ICT was added to skin snip microscopy for onchocerciasis. Participants were also tested for antibodies against Wb123 (LF and Ov16 (onchocerciasis antigens. In two districts, no participants were ICT or skin snip positive. In the third district, 3.5% were ICT positive and 0.7% were skin snip positive. In all the three districts, Wb123 prevalence was 0.6%. Overall, Ov16 prevalence was 6.9%. Ov16 prevalence among children 5-9 years old in the study was 2.5%. LF antigenemia prevalence was still above treatment threshold in one district despite ≥10 years of ivermectin-based MDA. The presence of Ov16 positive children suggested recent transmission of Onchocerca volvulus. This study showed the feasibility of integrated evaluation of onchocerciasis and LF but development of integrated robust methods for assessing transmission of both LF and onchocerciasis are needed to determine where MDA can be stopped safely in co-endemic areas.

Reforming health service delivery at district level in Ghana: the perspective of a district medical officer.

Science.gov (United States)

Agyepong, I A

1999-03-01

Many countries in sub-Saharan Africa face the problem of organizing health service delivery in a manner that provides adequate quality and coverage of health care to their populations against a background of economic recession and limited resources. In response to these challenges, different governments, including that of Ghana, have been considering or are in the process of implementing varying degrees of reform in the health sector. This paper examines aspects of health services delivery, and trends in utilization and coverage, using routine data over time in the Dangme West district of the Greater Accra region of Ghana, from the perspective of a district health manager. Specific interventions through which health services delivery and utilization at district level could be improved are suggested. Suggestions include raising awareness among care providers and health managers that increased resource availability is only a success in so far as it leads to improvements in coverage, utilization and quality; and developing indicators of performance which assess and reward use of resources at the local level to improve coverage, utilization and quality. Also needed are more flexibility in Central Government regulations for resource allocation and use; integration of service delivery at district level with more decentralized planning to make services better responsive to local needs; changes in basic and inservice training strategies; and exploration of how the public and private sectors can effectively collaborate to achieve maximum coverage and quality of care within available resources.

2017-08-01

Measurement of worker exposure to a thoracic health-related aerosol fraction is necessary in a number of occupational situations. This is the case of workplaces with atmospheres polluted by fibrous particles, such as cotton dust or asbestos, and by particles inducing irritation or bronchoconstriction such as acid mists or flour dust. Three personal and two static thoracic aerosol samplers were tested under laboratory conditions. Sampling efficiency with respect to particle aerodynamic diameter was measured in a horizontal low wind tunnel and in a vertical calm air chamber. Sampling performance was evaluated against conventional thoracic penetration. Three of the tested samplers performed well, when sampling the thoracic aerosol at nominal flow rate and two others performed well at optimized flow rate. The limit of flow rate optimization was found when using cyclone samplers. © The Author 2017. Published by Oxford University Press on behalf of the British Occupational Hygiene Society.

Despite rapid and tangible progress in vaccine coverage and in premature mortality rates registered in sub-Saharan Africa, inequities to access remain firmly entrenched, large pockets of low vaccination coverage persist, and coverage often varies considerably across regions, districts, and health facilities' areas of responsibility. This paper focuses on system-related factors that can explain disparities in immunization coverage among districts in Burkina Faso. A multiple-case study was conducted of six districts representative of different immunization trends and overall performance. A participative process that involved local experts and key actors led to a focus on key factors that could possibly determine the efficiency and efficacy of district vaccination services: occurrence of disease outbreaks and immunization days, overall district management performance, resources available for vaccination services, and institutional elements. The methodology, geared toward reconstructing the evolution of vaccine services performance from 2000 to 2006, is based on data from documents and from individual and group interviews in each of the six health districts. The process of interpreting results brought together the field personnel and the research team. The districts that perform best are those that assemble a set of favourable conditions. However, the leadership of the district medical officer (DMO) appears to be the main conduit and the rallying point for these conditions. Typically, strong leadership that is recognized by the field teams ensures smooth operation of the vaccination services, promotes the emergence of new initiatives and offers some protection against risks related to outbreaks of epidemics or supplementary activities that can hinder routine functioning. The same is true for the ability of nurse managers and their teams to cope with new situations (epidemics, shortages of certain stocks). The discourse on factors that determine the performance or

Low temperature district heating with reduced network supply and return temperature provides better match of the low quality building heating demand and the low quality heating supply from waste heat or renewable energy. In this paper, a hypothetical low temperature district heating network is designed to supply heating for 30 low energy detached residential houses. The network operational supply/return temperature is set as 55 °C/25 °C, which is in line with a pilot project carried out in Denmark. Two types of in-house substations are analyzed to supply the consumer domestic hot water demand. The space heating demand is supplied through floor heating in the bathroom and low temperature radiators in the rest of rooms. The network thermal and hydraulic conditions are simulated under steady state. A district heating network design and simulation code is developed to incorporate the network optimization procedure and the network simultaneous factor. Through the simulation, the overall system energy and exergy efficiencies are calculated and the exergy losses for the major district heating system components are identified. Based on the results, suggestions are given to further reduce the system energy/exergy losses and increase the quality match between the consumer heating demand and the district heating supply. -- Highlights: ► Exergy and energy analysis for low and medium temperature district heating systems. ► Different district heating network dimensioning methods are analyzed. ► Major exergy losses are identified in the district heating network and the in-house substations. ► Advantages to apply low temperature district heating are highlighted through exergy analysis. ► The influence of thermal by-pass on system exergy/energy performance is analyzed.

2017-01-01

Highlights: •Method for utilisation potential of industrial excess heat for district heating. •Industrial excess heat from thermal processes is quantified at single production units. •Linking of industrial excess heat sources and district heating demands done in GIS. •Excess heat recovery using direct heat transfer and heat pumps. •5.1% of the Danish district heating demand could be supplied by industrial excess heat. -- Abstract: Excess heat is available from various sources and its utilisation could reduce the primary energy use. The accessibility of this heat is however dependent amongst others on the source and sink temperature, amount and potential users in its vicinity. In this work a new method is developed which analyses excess heat sources from the industrial sector and how they could be used for district heating. This method first allocates excess heat to single production units by introducing and validating a new approach. Spatial analysis of the heat sources and consumers are then performed to evaluate the potential for using them for district heating. In this way the theoretical potential of using the excess heat for covering the heating demand of buildings is determined. Through the use of industry specific temperature profiles the heat usable directly or via heat pumps is further found. A sensitivity analysis investigates the impact of future energy efficiency measures in the industry, buildings and the district heating grid on the national potential. The results show that for the case study of Denmark, 1.36 TWh of district heat could be provided annually with industrial excess heat from thermal processes which equals 5.1% of the current demand. More than half of this heat was found to be usable directly, without the need for a heat pump.

Future Services for District Heating Solutions in Residential Districts

2014-06-01

Full Text Available The underlying assumption of this study is that in order to retain the competitiveness while reaching for the EU targets regarding low-energy construction, district heating companies need to develop new business and service models. How district heating companies could broaden their perspective and switch to a more service-oriented way of thinking is a key interest of our research. The used methods in our study are house builder interviews and a questionnaire. With the help of these methods we discussed the potential interest in heating related services acquiring a comprehensive understanding of the customer needs. The results indicate the importance of certain criteria when choosing the heating system in households: easiness, comfort and affordability seem to dominate the house builders’ preferences. Also environmental awareness seems to be for many an important factor when making a decision about the heating of the house. Altogether, based on the results of this study, we suggest that the prospects of district heating could benefit from highlighting certain aspects and strengths in the future. District heating companies need to increase flexibility, readiness to adopt new services, to invest in new marketing strategies and improving the communication skills.

Uranium districts defined by reconnaissance geochemistry in South Greenland

International Nuclear Information System (INIS)

Armour-Brown, A.; Steenfelt, A.; Kunzendorf, H.

1983-01-01

A reconnaissance exploration survey over 14 000 km 2 of Precambrian terrain in South Greenland using stream-sediment and stream-water samples delineated a central uranium district of 2000 km 2 with enhanced uranium levels and smaller anomalous zones in the south of the field area. Limited follow-up work located 8 pitchblende occurrences in this extensive district. The pitchblende is in veins which contain quartz, calcite, iron oxide, fluorite and minor sulphides. The isotopic (U-Pb) age of the pitchblende, which ranges from 1180-1090 Ma, corresponds to the late stages of Gardar alkaline igneous activity. It is concluded, therefore, that the reconnaissance geochemistry reflects a district-wide hydrothermal event related to the late volatile differentiates derived from the highly fractionated alkaline magma. A combination of primary and secondary features have complemented each other in enhancing the geochemical reconnaissance data and emphasized its importance but has not materially altered the interpretation.

Macronutrients, micronutrients, pH, salinity and moisture content were determined in soil samples from six farms in two farming towns in Assin North District in the Central Region of Ghana namely Assin Akonfudi and Assin Bereku. Soil samples were taken from cocoa farms, orange farms and palm oil plantations at three different depths. The nutrients determined were Primary macronutrients that was K, Secondary macronutrients that were Ca, Mg and Micronutrients that were, Cl, Co, Cu, Fe, Mn, Mo, Zn, Na and Se and Neutron Activation method and Atomic Absorption Spectrometry were used for the elemental analysis. The pHs were within the acidic range, ranging from 4.50-6.44. The top soil (0-5cm) had the higher pH followed by soil at the depth of 5-30cm and then soil at the depth of 30-40cm that is the pH decreased with depth. The salinity rather increased with depth ranging from 0.3l-2.98dS/m and the moisture content also ranged from 0.5-2.04%. For the soil samples taken from the cocoa farms, K recorded the highest concentration and Mo recorded the lowest concentration in the soil. For soil samples taken from orange farms, Ca recorded the highest concentration and Se recorded the lowest concentration in the soil and for soil samples taken from the palm oil plantations, Fe recorded the highest concentration and Mo recorded the lowest concentration in soil. The macronutrients ranged from 28591.19-6.49 mg/kg and the micronutrients ranged from <0.0004-20344.50 mg/kg. Soils in the cocoa farms were found to be more rich in nutrients and the soils in the palm oil plantations were found to be least rich in nutrients

Bonenberger, Marc; Aikins, Moses; Akweongo, Patricia; Wyss, Kaspar

2016-01-14

There is increasing evidence that good district management practices can improve health system performance and conversely, that poor and inefficient management practices have detrimental effects. The aim of the present study was to identify factors contributing to inefficient management practices of district health managers and ways to improve their overall efficiency. Nineteen semi-structured interviews were conducted with district health managers in three districts of the Eastern Region in Ghana. The 19 interviews conducted comprised 90% of the managerial workforce in these districts in 2013. A thematic analysis was carried out using the WHO's leadership and management strengthening framework to structure the results. Key factors for inefficient district health management practices were identified to be: human resource shortages, inadequate planning and communication skills, financial constraints, and a narrow decision space that constrains the authority of district health managers and their ability to influence decision-making. Strategies that may improve managerial efficiency at both an individual and organizational level included improvements to planning, communication, and time management skills, and ensuring the timely release of district funds. Filling District Health Management Team vacancies, developing leadership and management skills of district health managers, ensuring a better flow of district funds, and delegating more authority to the districts seems to be a promising intervention package, which may result in better and more efficient management practices and stronger health system performance.

Effect of sample size on bias correction performance

Science.gov (United States)

Reiter, Philipp; Gutjahr, Oliver; Schefczyk, Lukas; Heinemann, Günther; Casper, Markus C.

2014-05-01

The output of climate models often shows a bias when compared to observed data, so that a preprocessing is necessary before using it as climate forcing in impact modeling (e.g. hydrology, species distribution). A common bias correction method is the quantile matching approach, which adapts the cumulative distribution function of the model output to the one of the observed data by means of a transfer function. Especially for precipitation we expect the bias correction performance to strongly depend on sample size, i.e. the length of the period used for calibration of the transfer function. We carry out experiments using the precipitation output of ten regional climate model (RCM) hindcast runs from the EU-ENSEMBLES project and the E-OBS observational dataset for the period 1961 to 2000. The 40 years are split into a 30 year calibration period and a 10 year validation period. In the first step, for each RCM transfer functions are set up cell-by-cell, using the complete 30 year calibration period. The derived transfer functions are applied to the validation period of the respective RCM precipitation output and the mean absolute errors in reference to the observational dataset are calculated. These values are treated as "best fit" for the respective RCM. In the next step, this procedure is redone using subperiods out of the 30 year calibration period. The lengths of these subperiods are reduced from 29 years down to a minimum of 1 year, only considering subperiods of consecutive years. This leads to an increasing number of repetitions for smaller sample sizes (e.g. 2 for a length of 29 years). In the last step, the mean absolute errors are statistically tested against the "best fit" of the respective RCM to compare the performances. In order to analyze if the intensity of the effect of sample size depends on the chosen correction method, four variations of the quantile matching approach (PTF, QUANT/eQM, gQM, GQM) are applied in this study. The experiments are further

1999-01-01

A study was carried out in Central Kenya to compare the performance of dairy cattle under two different feeding systems, stall feeding in Kiambu and grazing in Nyandarua. A total of 23 dairy farmers were randomly selected, 11 from the Kiambu district with a total of 61 cows and 12 from Nyandarua district with a total of 102 cows. Data on milk production and reproduction was collected over a period of two years. Stall-fed cattle showed a significantly higher milk yield (P <0.05) than the grazed animals over a 10 month lactation period (3,150 vs 2,299 kg/lactation). In both feeding systems Ayshires performed better than the other breeds. The cross-bred animals compared well with pure-breds in the grazing system. Lactation yield increased with parity for the stall-fed animals while for grazed animals, milk yield declined from the 5th parity onwards. The calving intervals were long for both feeding systems (437 vs 513 days, stall-fed vs grazed, respectively). Services per conception were significantly lower (P <0.05) for stall-fed (1.85 vs 2.36) compared to grazed animals. Calving season did not have any significant effect on milk yield in both feeding systems but animals calving during the wet season, on average, had a slightly higher milk yield. Lactation curves for animals in both feeding systems did not show a distinct peak. Body weight and body condition score varied with the stage of lactation. (author)

District Energy Windsor

Energy Technology Data Exchange (ETDEWEB)

NONE

2002-07-01

This paper presents a summary of how District Energy Windsor operates. It includes a system site map and reasons why it is advantageous to get connected to a district heating system. District Energy Windsor is a division of the Windsor Utilities Commission. It was developed in 1996 and was the first in North America to supply both heating and cooling requirements. It supplies nearly 2 million square feet of heating and cooling for Windsor's city centre. The district energy system produces hot water or chilled water at a central plant. Energy is then piped out to buildings in the area, including the Art Gallery of Windsor, the Royal Bank Business Centre, the Windsor Justice Facility, the Windsor Casino, and Northwind Windsor. The energy, which is transferred through heat exchangers, is used for space heating, domestic hot water heating, and air conditioning. The 8 reasons for getting connected are: (1) less management costs, (2) lower energy costs, (3) lower level of risk management, (4) stable energy rates, (5) better use of building space, (6) reliable service, (7) reduced expansion costs, and (8) a cleaner environment. District heating improves air quality through reduced carbon dioxide and nitrogen oxide emissions. In addition, fuel delivery and storage are eliminated. figs.

Highlights: • Simulation of power plant, district heating network and heat users in detail and integrated. • Coupled calculation and analysis of the heat and pressure losses of the district heating network. • District heating is not preferable for very low heat load due to relatively high heat loss. • Lower design supply temperatures of the district heating network give higher system efficiency. - Abstract: Many studies have been carried out separately on combined heat and power and district heating. However, little work has been done considering the heat source, the district heating network and the heat users simultaneously, especially when it comes to the heating system with large-scale combined heat and power plant. For the purpose of energy conservation, it is very important to know well the system performance of the integrated heating system from the very primary fuel input to the terminal heat users. This paper set up a model of 300 MW electric power rated air-cooled combined heat and power plant using Ebsilon software, which was validated according to the design data from the turbine manufacturer. Then, the model of heating network and heat users were developed based on the fundamental theories of fluid mechanics and heat transfer. Finally the combined heat and power based district heating system was obtained and the system performances within multiscale scope of the system were analyzed using the developed Ebsilon model. Topics with regard to the heat loss, the pressure drop, the pump power consumption and the supply temperatures of the district heating network were discussed. Besides, the operational issues of the integrated system were also researched. Several useful conclusions were drawn. It was found that a lower design primary supply temperature of the district heating network would give a higher seasonal energy efficiency of the integrated system throughout the whole heating season. Moreover, it was not always right to relate low design

Full Text Available The purpose of this study was to assess the socioeconomic condition of maize seed and non-seed producers. A field survey was carried out in sixty households of Khanchikot VDC of Arghakhanchi district during May, 2014. The district was major seed producing district and Khanchikot was found better in seed production than other VDC in district. Simple random sampling technique was used to collect data using pre-tested interview schedule. About 57% were seed producer among the sample. The average family size of household was 5. Dependency ratio was less in seed producing households (0.41 than non-seed producers (0.72. Farmers were involved in the production of certified seed and the major (50% source of foundation seed was National Maize Research Program, Rampur, Chitwan. The external input like chemical fertilizer was used in fewer amounts in the study area. The seed test was done at regional laboratory, Bhairahawa and sold to DADO, Arghakhanchi. Decision on loan taking, business operation and bank account were taken by males whereas cropping pattern, deficit labor use, religious and social works related decision were taken by females in the household. Major problem in maize production were lack of technical assistance followed by inadequate irrigation facilities. Proper training, extension service and government support on inputs would help in better socio-economic condition and production of maize.

Full Text Available The level of education and its response to different educational opportunities vary from one spatial unit to another depending on various factors like social, economic, cultural, and institutional. It is understood that certain regions acquire relative advancements over others in terms of human resource development and human capital formation. The key purpose of this research is to examine the intra-district disparities in primary education in Bankura District one of the districts of West Bengal. It ranks 11thamong the 19 districts of West Bengal (Human Development Report, 2007.  Overall literacy rate of the district stands at 70.26% but the district scores low in terms of female literacy rates, which is 60.05%,whereas the male literacy rate is 80.05%, which is a huge gender literacy gap of 20%. There are also regional inequalities existing at block level. Kotulpur ranks first with a literacy rate of 78.01% while Saltora occupies the bottom position with literacy rate of just 61.45% (Census of India, 2011. The level of educational development is dependent on several factors—enrolment ratio, dropout and repetition rates, pupil-teacher ratio, habitations covered by educational institutions, space-student ratio, drinking water and sanitation facilities in school, etc. In this context, the present study aims at examining the issues of intra-district disparities in educational attainment with regard to various educational amenities of Bankura district, West Bengal. Ten attributes have been selected to examine the level of development in primary education. It is clear from the study that the level of development in eastern part of the district is relatively better in comparison to other regions. Economic backwardness and physical bottlenecks continue to be major issues in western blocks.

2018-06-07

State agencies play a critical role in providing school districts with guidance and technical assistance on school nutrition issues, including food and beverage marketing practices. We examined associations between state-level guidance and the policies and practices in school districts regarding food and beverage marketing and promotion. State policy guidance was positively associated with districts prohibiting advertisements for junk food or fast food restaurants on school property. Technical assistance from states was negatively associated with 2 district practices to restrict marketing of unhealthy foods and beverages, but positively associated with 1 practice to promote healthy options. These findings may help inform the guidance that states provide to school districts and help identify which districts may need additional assistance to address marketing and promotion practices.

Full Text Available This study is a serological and virological examination of the border disease virus (BDV in sheep at 1–5 years of age from private small scale production units of less than 20 sheep per unit, in the Kars District of Turkey. For this purpose, blood sera from 460 sheep were tested for antibodies against BDV using a commercial enzyme-linked immunosorbent assay (ELISA. Since BDV causes persistent infection, antigen-ELISA was also performed for this agent. Seropositivity rate was detected to be 74.57%. In addition, the BDV antigen was detected in one sample of seronegative sera (0.85%. Reverse transcription polymerase chain reaction (RT-PCR technique was used to determine the presence of pestivirus nucleic acid by using 5’UTR primer pair. Pestivirus nucleic acid was found in 2 of 117 seronegative samples (1.71% by RT-PCR. The results suggest that the infection was spreading in private small scale production units. Furthermore, recommendations for the control of BDV infection are presented. This study is the first molecular and serological study to determine viroprevalence and seroprevalence of BDV infection in sheep in the Kars District of Turkey.

Energy Neutral Districts in 2050. The Dutch Approach

Energy Technology Data Exchange (ETDEWEB)

Jablonska, B.; Roossien, B.; Ruijg, G.J.; Visser, H.; Bakker, E.J. [Energy research Centre of the Netherlands ECN, Petten (Netherlands); Willems, E. [Cauberg-Huygen Raadgevende Ingenieurs, Amsterdam (Netherlands)

According to the EPBD, from the end of 2020 on all new buildings should be built as nearly zero energy buildings. Instead of focusing on buildings only, a district approach to energy supply and consumption can be advantageous as regards the energy performance and economics. The potential of renewable energy technologies can be utilized to a larger extent while fewer energy generators are needed. An example is a so called energy-hub, in which exchange, conversion and seasonal storage of energy can lead to energy neutral districts before 2050. The Dutch study Transition in Energy and Process for a Sustainable District Development (Transep-DGO), financed largely by the AgentschapNL, has shown that this is possible. For energy neutral district development in 2050, six innovative energy concepts have been elaborated and the extent of energy neutrality in 2020, 2035 and 2050 calculated. Three concepts are based on an idea of an energy hub - bio hub, geo hub and a solar hub. Other concepts are all-electric, conventional and hydrogen concepts. Calculations show that implementation of each of the concepts can lead to energy neutral districts in 2050 or even earlier. When personal transport is included, energy neutrality in 2050 is not feasible. Based on the six general concepts, the most optimal energy concepts tailored for four Dutch cities have been elaborated as pilots, in close cooperation with municipality representatives. Solar hub has been dynamically simulated in order to show the added value of the exchange, conversion and storage of energy flows on a district scale. Energy Pattern Generator (EPG) has been applied for simulation of a virtual district with 1,000 dwellings of various categories. A solar hub with collective heat storage can reduce the demanded storage capacity by 26%, and the total required solar collector surface by 30% at maximum compared to individual seasonal heat storage capacity in dwellings that are not connected in an energy hub.

Gower, Amy L; Cousin, Molly; Borowsky, Iris W

2017-03-01

Although nearly all states in the United States require school districts to adopt anti-bullying policies, little research examines the effect of these policies on student bullying and health. Using a statewide sample, we investigated associations between the quality of school district anti-bullying policies and student bullying involvement and adjustment. School district anti-bullying policies (N = 208) were coded for their quality based on established criteria. District-level data were combined with student reports of bullying involvement, emotional distress, and school connectedness from a state surveillance survey of 6th, 9th, and 12th grade students (N = 93,437). Results indicated that policy quality was positively related to bullying victimization. Furthermore, students reporting frequent perpetration/victimization who also attended districts with high-quality policies reported more emotional distress and less school connectedness compared with students attending districts with low quality policies. Although statistically significant, the magnitude of these associations was small. Having a high-quality school district anti-bullying policy is not sufficient to reduce bullying and protect bullying-involved young people. Future studies examining policy implementation will inform best practices in bullying prevention. © 2017, American School Health Association.

Reinstating district nursing: A UK perspective.

Science.gov (United States)

Morris, Hannah

2017-09-01

As policy directives gather pace for service provision to be delivered in primary care, district nursing has not been recognised as a valuable asset to facilitate this agenda. Investment in district nursing and specialist district nursing education has fallen. This is concurrent with an ageing district nursing workforce, a lack of recruitment and growing caseloads, as district nursing adapts to meet the challenges of the complexities of contemporary healthcare in the community. The district nurse role is complex and multifaceted and includes working collaboratively and creatively to coordinate care. Redressing the shortages of specialist district nurse practitioners with increased numbers of health care support workers will not replace the skill, knowledge, experience required to meet the complex care needs of today's society. District nursing needs to be reinstated as the valuable asset it is, through renewed investment in the service, research development and in specialist practice education. To prevent extinction district nurses need to be able to demonstrate and articulate the complexities and dynamisms of the role to reinstate themselves to their commissioners as a valuable asset for contemporary practice that can meet current health and social care needs effectively.

1999-07-01

A study was carried out in Central Kenya to compare the performance of dairy cattle under two different feeding systems, stall feeding in Kiambu and grazing in Nyandarua. A total of 23 dairy farmers were randomly selected, 11 from the Kiambu district with a total of 61 cows and 12 from Nyandarua district with a total of 102 cows. Data on milk production and reproduction was collected over a period of two years. Stall-fed cattle showed a significantly higher milk yield (P <0.05) than the grazed animals over a 10 month lactation period (3,150 vs 2,299 kg/lactation). In both feeding systems Ayshires performed better than the other breeds. The cross-bred animals compared well with pure-breds in the grazing system. Lactation yield increased with parity for the stall-fed animals while for grazed animals, milk yield declined from the 5th parity onwards. The calving intervals were long for both feeding systems (437 vs 513 days, stall-fed vs grazed, respectively). Services per conception were significantly lower (P <0.05) for stall-fed (1.85 vs 2.36) compared to grazed animals. Calving season did not have any significant effect on milk yield in both feeding systems but animals calving during the wet season, on average, had a slightly higher milk yield. Lactation curves for animals in both feeding systems did not show a distinct peak. Body weight and body condition score varied with the stage of lactation. (author) 6 refs, 2 figs, 4 tabs

The assessment of global thermo-energy performances of existing district heating systems optimized by harnessing renewable energy sources

Science.gov (United States)

Şoimoşan, Teodora M.; Danku, Gelu; Felseghi, Raluca A.

2017-12-01

Within the thermo-energy optimization process of an existing heating system, the increase of the system's energy efficiency and speeding-up the transition to green energy use are pursued. The concept of multi-energy district heating system, with high harnessing levels of the renewable energy sources (RES) in order to produce heat, is expected to be the key-element in the future urban energy infrastructure, due to the important role it can have in the strategies of optimizing and decarbonizing the existing district heating systems. The issues that arise are related to the efficient integration of different technologies of harnessing renewable energy sources in the energy mix and to the increase of the participation levels of RES, respectively. For the holistic modeling of the district heating system, the concept of the energy hub was used, where the synergy of different primary forms of entered energy provides the system a high degree energy security and flexibility in operation. The optimization of energy flows within the energy hub allows the optimization of the thermo-energy district system in order to approach the dual concept of smart city & smart energy.

Prasetyo, R H

2016-03-01

The purpose of this study was to investigate the prevalence of house rat zoonotic intestinal parasites from Surabaya District, East Java, Indonesia that have the potential to cause opportunistic infection in humans. House rat fecal samples were collected from an area of Surabaya District with a dense rat population during May 2015. Intestinal parasites were detected microscopically using direct smear of feces stained with Lugol's iodine and modified Ziehl-Neelsen stains. The fecal samples were also cultured for Strongyloides stercoralis. Ninety-eight house rat fecal samples were examined. The potential opportunistic infection parasite densities found in those samples were Strongyloides stercoralis in 53%, Hymenolepis nana in 42%, Cryptosporidium spp in 33%, and Blastocystis spp in 6%. This is the first report of this kind in Surabaya District. Measures need to be taken to control the house rat population in the study area to reduce the risk of the public health problem.

ACS sampling system: design, implementation, and performance evaluation

Science.gov (United States)

Di Marcantonio, Paolo; Cirami, Roberto; Chiozzi, Gianluca

2004-09-01

By means of ACS (ALMA Common Software) framework we designed and implemented a sampling system which allows sampling of every Characteristic Component Property with a specific, user-defined, sustained frequency limited only by the hardware. Collected data are sent to various clients (one or more Java plotting widgets, a dedicated GUI or a COTS application) using the ACS/CORBA Notification Channel. The data transport is optimized: samples are cached locally and sent in packets with a lower and user-defined frequency to keep network load under control. Simultaneous sampling of the Properties of different Components is also possible. Together with the design and implementation issues we present the performance of the sampling system evaluated on two different platforms: on a VME based system using VxWorks RTOS (currently adopted by ALMA) and on a PC/104+ embedded platform using Red Hat 9 Linux operating system. The PC/104+ solution offers, as an alternative, a low cost PC compatible hardware environment with free and open operating system.

Sampling Approaches for Multi-Domain Internet Performance Measurement Infrastructures

Energy Technology Data Exchange (ETDEWEB)

Calyam, Prasad

2014-09-15

The next-generation of high-performance networks being developed in DOE communities are critical for supporting current and emerging data-intensive science applications. The goal of this project is to investigate multi-domain network status sampling techniques and tools to measure/analyze performance, and thereby provide “network awareness” to end-users and network operators in DOE communities. We leverage the infrastructure and datasets available through perfSONAR, which is a multi-domain measurement framework that has been widely deployed in high-performance computing and networking communities; the DOE community is a core developer and the largest adopter of perfSONAR. Our investigations include development of semantic scheduling algorithms, measurement federation policies, and tools to sample multi-domain and multi-layer network status within perfSONAR deployments. We validate our algorithms and policies with end-to-end measurement analysis tools for various monitoring objectives such as network weather forecasting, anomaly detection, and fault-diagnosis. In addition, we develop a multi-domain architecture for an enterprise-specific perfSONAR deployment that can implement monitoring-objective based sampling and that adheres to any domain-specific measurement policies.

This study sought to determine the influence of individual factors on active transportation to school among Danish seventh graders and whether school district factors are associated with such behaviour independently of individual factors. Mixed effects logistic regression models determined the effects of individual (gender, family affluence, enjoyment of school and academic performance) and school district factors (educational level, household savings, land use and size) on active transportation to school (by foot, bicycle or other active means) among 10 380 pupils aged 13-15 years nested in 407 school districts. Of all students, 64.4% used active transportation to school daily. Boys, those with perceived higher school performance and those with lower family affluence were more likely to use active transportation to school. After adjustment for all individual factors listed above, high household savings at the school district level was associated with higher odds of active transportation to school. As factors of land use, low level of farming land use and high proportion of single houses were associated with active transportation to school. Policies aiming at reducing social inequalities at the school district level may enhance active transportation to school. School districts with farming land use face barriers for active transportation to school, requiring special policy attention.

Calculating the marginal costs of a district-heating utility

International Nuclear Information System (INIS)

Sjoedin, Joergen; Henning, Dag

2004-01-01

District heating plays an important role in the Swedish heat-market. At the same time, the price of district heating varies considerably among different district-heating utilities. A case study is performed here in which a Swedish utility is analysed using three different methods for calculating the marginal costs of heat supply: a manual spreadsheet method, an optimising linear-programming model, and a least-cost dispatch simulation model. Calculated marginal-costs, obtained with the three methods, turn out to be similar. The calculated marginal-costs are also compared to the actual heat tariff in use by the utility. Using prices based on marginal costs should be able to bring about an efficient resource-allocation. It is found that the fixed rate the utility uses today should be replaced by a time-of-use rate, which would give a more accurate signal for customers to change their heat consumptions. (Author)

Full Text Available Moving towards the development and realization of the creative city due to the status of the city as a place of forming knowledge society contexts, and the importance of cities in economic development is very necessary and important. This paper aims to examine the components of the creative city in Zahedan and tries to move toward urban creativity. Considering the components of this research, it is an applied study, which is conducted through a descriptive-analytical method. The research includes 20 indicators for the creative city. A researcher made questionnaire is used to collect data. In addition, SPSS and GIS softwares are used to analyze the data. The statistical population is the five districts of Zahedan City, in which 383 residents were selected and studied through cluster and systematic random sampling in all districts of the city. The ranking results of districts in the creative city indicators show that district 1 is the most desirable district and district 3 is the most undesirable and the most deprived district with informal and disturbed settlements. The effectiveness of each component of the creative city indicators was studied in the regression analysis. It was found that the effectiveness of all components is not identical in the realization of the creative city in Zahedan. They act in the form of a chain and the stability of the chain depends on the planning and investment in all of the sub-indicators of these components.

Current situation of midwives in indonesia: Evidence from 3 districts in West Java Province

Science.gov (United States)

2010-01-01

Background The village midwife is a central element of Indonesia's strategy to improve maternal and child health and family planning services. Recently there has been concern that the midwives were not present in the villages to which they had been assigned. To determine the extent to which this was the case we conducted a field-based census and survey of village midwives in three districts in West Java Province, Indonesia. Findings In June 2009 we interviewed a random sample of village midwives from three districts - Ciamis, Garut and Sukabumi - in West Java Province. Trained interviewers visited all villages represented in the sample to interview the midwives. We also obtained information about the midwives and their professional activities in the last year. Thirty percent of village midwives had moved to another location in the 12 months between the end of 2008, when the sampling frame was constructed, and December 2009 when the survey was conducted; most had moved to a government health center or another village. Of those who were present, there was considerable variation between districts in age distribution and qualifications. The total number of services provided was modest, also with considerable variation between districts. The median number of deliveries assisted in the last year was 64; the amount and mix of family planning services provided varied between districts and were dominated by temporary methods. Conclusions Compared to an earlier survey in an adjacent province, the village midwives in these three districts were younger, had spent less time in the village and a higher proportion were permanent civil servants. A high proportion had moved in the previous year with most moving to a health center or another village. The decision to move, as well as the mix of services offered, seems to be largely driven by opportunities to increase their private practice income. These opportunities are greater in urban areas.

Hydrazine Determination in Sludge Samples by High Performance Liquid Chromatography

Energy Technology Data Exchange (ETDEWEB)

G. Elias; G. A. Park

2006-02-01

A high-performance liquid chromatographic method using ultraviolet (UV) detection was developed to detect and quantify hydrazine in a variety of environmental matrices. The method was developed primarily for sludge samples, but it is also applicable to soil and water samples. The hydrazine in the matrices was derivatized to their hydrazones with benzaldehyde. The derivatized hydrazones were separated using high performance liquid chromatography (HPLC) with a reversed-phase C-18 column in an isocratic mode with methanol-water (95:5, v/v), and detected with UV detection at 313 nm. The detection limit (25 ml) for the new analytical method is 0.0067 mg ml-1of hydrazine. Hydrazine showed low recovery in soil samples because components in soil oxidized hydrazine. Sludge samples that contained relatively high soil content also showed lower recovery. The technique is relatively simple and cost-effective, and is applicable for hydrazine analysis in different environmental matrices.

Uranium occurrences in the Gordonia and Kuruman districts

International Nuclear Information System (INIS)

Levin, M.

1978-11-01

This report highlights uranium occurrences discovered by the author in the Kuruman and Gordonia Districts. These discoveries are the result of follow-up work of the regional geological, hydrological and hydrochemical studies of the area, undertaken by the Geology Division of the Atomic Energy Board since 1974. A surficial uranium deposit was discovered on the farm Rus en Vrede in the Kuruman District, at the junction of a palaeo-river with the Kuruman River. Uranium occurs in carbonaceous diatomaceous earth, with surface samples assaying up to 308 ppm U 3 O 8 . As uranium is also present in calcrete 18 km south of this deposit, there is a distinct possibility that significant surficial deposits may occur under the Kalahari sand cover in this area. In the Gordonia District an interesting discovery was made on the farm Tsongnapan where four boreholes, drilled for water, intersected radioactive bands in the Dwyka Tillite Formation. These rocks, which outcrop in the northeast corner of the Tsongnapan, also proved to be radioactive. Some 35 km to the east of this occurrence, borehole logging indicated the existence of an anomalous zone near the base of the Dwyka. In some of these boreholes uranium anomalies were also found in the calcrete and gravel of the Kalahari Formation. It is evident, therefore, that the Gordonia District has the potential of becoming an economically important uranium province. A radiometric ground survey of one of the pans indicated that wind and water action is possibly responsible for the local dispersion and segregation of radioactive minerals [af

Italian industrial districts: A model of success or a weak productive system?

Directory of Open Access Journals (Sweden)

Daniele Schilirò

2012-10-01

Full Text Available The present contribution focuses on two issues. The first one concerns the characteristics of industrial districts and the increasing weight of these districts in the Italian system of production. The second issue is about the competitiveness of the Italian industrial districts, if they represent a model of success or rather a weak system of production. Thus, the transformation of the industrial districts is examined and the strengths and weaknesses are highlighted. One argument that comes out of this investigation is that industrial districts are strongly influenced by institutions, territory, and also by the social and cultural environment. The second argument regards the competitiveness of this Italian industrial development model, based on SMEs, which is founded on the specialization of productions, on innovation and internationalization. The paper argues that this model, which represents the ``Made in Italy'', is still a strong and dynamic system which has shown good performances and it represents a paradigm of lasting competitiveness, even if it is restrained by many external chronic constraints.

Boitsov, A.V.; Nikolsky, A.L.

2001-01-01

Uranium deposits are discovered in 15 ore districts of the Russian Federation. They are subdivided into four groups: Streltsovsky district with existing production centre, Stavropolsky district with depleted deposits, three prospective districts and ten reserve districts. The overview of new data on these districts is presented. Streltsovsky district with Priargunsky Production Centre include 19 molybdenum-uranium deposits of structure-bound volcanic type in caldera. The main activities in Stavropolsky district with two depleted uranium deposits are connected with restoration works and wastes rehabilitation. Except Streltsovsky district there are no more deposits in the Russian Federation prepared for uranium production. At the same time some uranium deposits of Vitimsky, Zauralsky, and West-Siberian districts are prospective for new development of production centres. They belong to the sandstone type, related to paleovalley or basal channel, and are suitable for ISL operation. The deposits of the other districts are considered to be reserve and considered unprofitable for uranium production at present and in the nearest future. The biggest of them is Aldansky district with gold-uranium deposits in potassium metasomatites in areas of Mesozoic activation of Archean cratons. Central Transbaikalsky, Yeniseisky, Yergeninsky, Onezhsky, Ladozhsky, Bureinsky, Khankaisky, Volgo-Uralsky reserve districts include mainly small-size deposits of vein, volcanic, surficial and metasomatite types with low uranium grades.

2009-03-01

To estimate the yellow fever (YF) vaccine coverage for the endemic and non-endemic areas of Bolivia and to determine whether selected districts had acceptable levels of coverage (>70%). We conducted two surveys of 600 individuals (25 x 12 clusters) to estimate coverage in the endemic and non-endemic areas. We assessed 11 districts using lot quality assurance sampling (LQAS). The lot (district) sample was 35 individuals with six as decision value (alpha error 6% if true coverage 70%; beta error 6% if true coverage 90%). To increase feasibility, we divided the lots into five clusters of seven individuals; to investigate the effect of clustering, we calculated alpha and beta by conducting simulations where each cluster's true coverage was sampled from a normal distribution with a mean of 70% or 90% and standard deviations of 5% or 10%. Estimated coverage was 84.3% (95% CI: 78.9-89.7) in endemic areas, 86.8% (82.5-91.0) in non-endemic and 86.0% (82.8-89.1) nationally. LQAS showed that four lots had unacceptable coverage levels. In six lots, results were inconsistent with the estimated administrative coverage. The simulations suggested that the effect of clustering the lots is unlikely to have significantly increased the risk of making incorrect accept/reject decisions. Estimated YF coverage was high. Discrepancies between administrative coverage and LQAS results may be due to incorrect population data. Even allowing for clustering in LQAS, the statistical errors would remain low. Catch-up campaigns are recommended in districts with unacceptable coverage.

2017-01-01

ABSTRACT Background: Poor quality of care and access to effective and affordable interventions have been attributed to constraints and bottlenecks within and outside the health system. However, there is limited understanding of health system barriers to utilization and delivery of appropriate, high-impact, and cost-effective interventions at the point of service delivery in districts and sub-districts in low-income countries. In this study we illustrate the use of the bottleneck analysis approach, which could be used to identify bottlenecks in service delivery within the district health system. Methods: A modified Tanahashi model with six determinants for effective coverage was used to determine bottlenecks in service provision for maternal and newborn care. The following interventions provided during antenatal care were used as tracer interventions: use of iron and folic acid, intermittent presumptive treatment for malaria, HIV counseling and testing, and syphilis testing. Data from cross-sectional household and health facility surveys in Mayuge and Namayingo districts in Uganda were used in this study. Results: Effective coverage and human resource gaps were identified as the biggest bottlenecks in both districts, with coverage ranging from 0% to 66% for effective coverage and from 46% to 58% for availability of health facility staff. Our findings revealed a similar pattern in bottlenecks in both districts for particular interventions although the districts are functionally independent. Conclusion: The modified Tanahashi model is an analysis tool that can be used to identify bottlenecks to effective coverage within the district health system, for instance, the effective coverage for maternal and newborn care interventions. However, the analysis is highly dependent on the availability of data to populate all six determinants and could benefit from further validation analysis for the causes of bottlenecks identified.

Extensive studies on the rationale, the potential and the technology of nuclear district heating have been performed in Switzerland. Beside economics the safety aspects were of primary importance. Due to the high costs to transport heat the heating reactor tend to be small and therefore, minimally staffed and located close to population centers. Stringed safety rules are therefore applying. Gas cooled reactors are well suited as district heating reactors since they have due to their characteristics several inherent features, significant safety margins and a remarkable radioactivity retention potential. Some ways to mitigate the effects of water ingress and graphite corrosion are under investigation. (author). 5 refs, 3 figs

The Bribery Act 2010: an overview for district nurses.

Science.gov (United States)

Griffith, Richard; Tengnah, Cassam

2012-10-01

The Bribery Act 2010 has been in force for a little over a year and has already served to reinforce the need for NHS organisations to adopt a proactive approach to preventing any suggestion that their staff are accepting inducements, in the form of gifts or hospitality, that could influence their performance. The robust policies on the acceptance of gifts and hospitality demanded by the 2010 Act require district nurses to be very cautious when offered a gift by a patient or commercial organisation. This article considers the implications of the Bribery Act 2010 on district nurse practice and the implications of failing to meet its provisions.

Full Text Available In this study Tehran’s drinking water was evaluated for the presence of chlorinated hydrocarbons during spring and summer of 2009. Chlorinated hydrocarbons are an important class of environmental pollutants that cause adverse health effects on human’s kidney, liver and central nervous systems. In this study six water districts were selected for taking drinking water samples in the city of Tehran as well as one location outside the city limits. The samples were analyzed by GC/MS using EPA method 8260. The average concentrations of 1,1-dichloroethylene, 1,2 Dichloromethane, Tetra chloromethane, Trichloroethylene and tetra chloroethylene were determined during a 7 month period and the results were 0.04ppb, 0.52ppb, 0.01ppb, 0.24ppb, 0.03ppb respectively. The highest concentration of chlorinated hydrocarbon observed in Tehran’s drinking water was Trichloroethylene and the lowest concentration was Tetra chloromethane. Districts 5 and 6 showed the highest concentrations of chlorinated hydrocarbons in the city of Tehran.

The optimal management of resources within South African state hospitals has been hampered by a paucity of data due to a lack of robust auditing information systems. This study reviews the use of a Hybrid Electronic Medical Record (HEMR) system to capture and aggregate data pertaining to the inpatient service demands on a South African tertiary surgical service. This dataset was used to analyse the appropriateness of tertiary surgical resource utilisation. The HEMR system was implemented at Greys Hospital, in the city of Pietermaritzburg, Kwa-Zulu Natal, South Africa on 1 January 2013. Inpatient data pertaining to surgical admissions and operative interventions were captured prospectively. Following an 18-month study period, the data were extracted, aggregated and analysed. The district referral hospitals were mapped, and district surgical procedures performed within the tertiary center were identified and quantified. Results: 7314 patients were admitted and managed by the tertiary surgical service during the study period. The median patient age was 33 years (IQR 6.5-42.4 years). 59.7% were male and 40.3% were female. General, trauma and paediatric surgical admissions constituted 54.8%, 28.6% and 16.6% respectively. Emergency admissions constituted 62.4% and elective admissions 37.6%. Referral sources were captured for 6653 (91%) of the cohort. 4338 (65.2%) patients were referred from district hospitals. The district hospital (Northdale) closest to Greys Hospital was responsible for 1675 (25.2%) of surgical referrals. 4174 operative procedures were performed during the study period, 54.7% performed as an emergency, 34.1% electively and 11.2% semi-electively. The median waiting time for emergency operative intervention was 535 minutes (IQR 130-663). A total of 1272 (30.5%) operative procedures performed were assessed as district-level operations. The time intervals of 07:00-07:59 and 17:00-17:59 were identified as the time periods during which the least number of

Foods and beverages marketed in schools are typically of poor nutritional value. School districts may adopt policies and practices to restrict marketing of unhealthful foods and to promote healthful choices. Students' exposure to marketing practices differ by school demographics, but these differences have not yet been examined by district characteristics. We analyzed data from the 2012 School Health Policies and Practices Study to examine how food and beverage marketing and promotion policies and practices varied by district characteristics such as metropolitan status, size, and percentage of non-Hispanic white students. Most practices varied significantly by district size: a higher percentage of large districts than small or medium-sized districts restricted marketing of unhealthful foods and promoted healthful options. Compared with districts whose student populations were majority (>50%) non-Hispanic white, a higher percentage of districts whose student populations were minority non-Hispanic white (≤50% non-Hispanic white) prohibited advertising of soft drinks in school buildings and on school grounds, made school meal menus available to students, and provided families with information on school nutrition programs. Compared with suburban and rural districts, a higher percentage of urban districts prohibited the sale of soft drinks on school grounds and used several practices to promote healthful options. Preliminary findings showing significant associations between district demographics and marketing policies and practices can be used to help states direct resources, training, and technical assistance to address food and beverage marketing and promotion to districts most in need of improvement.

The technology of DEHP and DBP detection by high performance liquid chromatography coupled with ultraviolet detection (HPLC-UV) was developed and applied in analysis of local water sources from agriculture, industrial and residential areas. Under the optimized sample pretreatment and detection conditions, DEHP and DBP were well separated and detected in 4 mins. The detection limit of DBP was 0.002 mg/L and DEHP was 0.006 mg/L, and it meets the Chinese National Standard limitations for drinking water quality. The linear correlation coefficient of DBP and DEHP standard calibration curves was 0.9998 and 0.9995. The linear range of DBP was 0.020 mg/L ∼20.0 mg/L, with the standard deviation of 0.560% ∼5.07%, and the linear range of DEHP was 0.060 mg/L ∼15.0 mg/L, with the standard deviation of 0.546% ∼5.74%. Ten water samples from Jinwan district of Zhuhai in Guangdong province of China were analyzed. However, the PAEs amounts found in the water sources from industrial areas were higher than the agriculture and residential areas, industries grow incredibly fast in the district in recently years and more attention should be paid to the increasing risks of water sources pollution.

Uranium districts in South Greenland

International Nuclear Information System (INIS)

Armour-Brown, A.; Tukiainen, T.; Wallin, B.

1981-01-01

A short review is given of reconnaissance work in South Greenland. The work has demonstrated that there are areas in the Motzfeldt centre of at least 1 km 2 with continuously high radioactivity. If the uranium content of these radioactive zones are sufficiently high, then potential ore tonnages could prove to be substantial. The reconnaissance exploration has proved that uranium mineralization is widely distributed in the Narssaq-Narssarssuaq district. It is, no doubt, responsible for the high uranium values in the exploration geochemical samples. Although the size of the pitchblende occurences which have been found so far are small, the high grade of the mineralisation, the great frequency of the fracturing and the evidence for an all pervasive mineralising event over a wide area indicate that there is a good possibility of finding economic mineralisation within the Narssaq-Narssarssuaq area. The area as a whole may, perhaps, be termed a ''uranium mineral district''. As the potential targets are small, only detailed follow-up exploration will establish this. At the same time more detailed work on individual showings, and geological mapping to demonstrate the relative ages of the various petrological and mineralising events, will establish the possible origin of this uranium mineralisation.

Mujasi, Paschal N; Puig-Junoy, Jaume

2015-01-01

A key policy question for the government of Uganda is how to equitably allocate primary health care pharmaceutical budgets to districts. This paper seeks to identify variables influencing current primary health care pharmaceutical expenditure and their usefulness in allocating prospective pharmaceutical budgets to districts. This was a cross sectional, retrospective observational study using secondary administrative data. We collected data on the value of pharmaceuticals procured by primary health care facilities in each district from National Medical Stores for the financial year 2011/2012. The dependent variable was expressed as per capita district pharmaceutical expenditure. By reviewing literature we identified 26 potential explanatory variables. They include supply, need and demand, and health system organization variables that may influence the demand and supply of health services and the corresponding pharmaceutical expenditure. We collected secondary data for these variables for all the districts in Uganda (n = 112). We performed econometric analysis to estimate parameters of various regression models. There is a significant correlation between per capita district pharmaceutical expenditure and total district population, rural poverty, access to drinking water and outpatient department (OPD) per capita utilisation.(P Uganda (Adjusted R(2) = 0.528). All variables in the model are significant (p Uganda are: district outpatient department attendance per capita, total district population, total number of government health facilities in the district and the district human poverty index.

This is a descriptive qualitative research with population sample of the Office of Settlement and Regional Infrastructure of Pekanbaru City, Senapelan District Government, NGOs, community leaders, and private parties. Data are collected through interview, observation and documentation, which is then analyzed using qualitative analysis technique. This research finds that the policy of the development of Water Front City at Village Kampung Baru sub-district Senapelan Pekanbaru is not implemented optimally. This situation can be seen through a variety of indicators related to the implementation of development policies of Water Front City at Village Kampung Baru sub-district Senapelan Pekanbaru in that the effect of interest policies, benefits, desire for change, the process of decision-making, implementing programs and supporting resources have not been implemented effectively. The curbing factors in implementing development policies in the District Water Front City Senapelan Pekanbaru are mostly due to the lack of human resources, process of compensation and other inadequate financing, and managerial instruments that are unsupported to the implementation of development programs of Water Front City at Village Kampung Baru sub-district Senapelan Pekanbaru.

Oshamanbe district is on the northern extension of the so-called green tuff district in northeastern Japan, and the sedimentary rocks in a sea area and volcanic rocks from Miocene to Pleistocene widely distribute. The authors carried out the geological survey of this district, and published the results as the geological features in Oshamanbe district. The volcanic rocks distributing in this district range from andesite to dacite and rhyolite. Their lithofacies are mostly volcanic breccia and tuff breccia, accompanied by lava and dikes. This time, the measurement of the age of these volcanic rocks was carried out, and the stratigraphical table made by the authors was investigated. It is considered that those age values offer important information for determining the age of the Setana formation. The outline of the geological features, the samples for the measurement, the method of measurement of Ar isotopic ratio and K, and the results of measurement are reported. As the results, 4.38 - 4.47 Ma were obtained for Garogawa volcanic rocks, and 2.59 Ma for Shamanbesan volcanic rocks. The period of sedimentation of the Setana formation was from the latter period of Pliocene to pleistocene. (Kako, I.)

For most of the population in Africa, district hospitals represent the first level of access for emergency and essential surgical services. The present study documents the number and availability of surgical and obstetrical care providers as well as the types of surgical and obstetrical procedures being performed at 10 first-referral district hospitals in Ghana. After institutional review board and governmental approval, a study team composed of Ghanaian and American surgeons performed on-site surveys at 10 district hospitals in 10 different regions of Ghana in August 2009. Face-to-face interviews were conducted documenting the numbers and availability of surgical and obstetrical personnel as well as gathering data relating to the number and types of procedures being performed at the facilities. A total of 68 surgical and obstetrical providers were interviewed. Surgical and obstetrical care providers consisted of Medical Officers (8.5%), nurse anesthetists (6%), theatre nurses (33%), midwives (50.7%), and others (4.5%). Major surgical cases represented 37% of overall case volumes with cesarean section as the most common type of major surgical procedure performed. The most common minor surgical procedures performed were suturing of lacerations or episiotomies. The present study demonstrates that there is a substantial shortage of adequately trained surgeons who can perform surgical and obstetrical procedures at first-referral facilities. Addressing human resource needs and further defining practice constraints at the district hospital level are important facets of future planning and policy implementation.

Experimental performance evaluation of two stack sampling systems in a plutonium facility

International Nuclear Information System (INIS)

Glissmeyer, J.A.

1992-04-01

The evaluation of two routine stack sampling systems at the Z-Plant plutonium facility operated by Rockwell International for USERDA is part of a larger study, sponsored by Rockwell and conducted by Battelle, Pacific Northwest Laboratories, of gaseous effluent sampling systems. The gaseous effluent sampling systems evaluated are located at the main plant ventilation stack (291-Z-1) and at a vessel vent stack (296-Z-3). A preliminary report, which was a paper study issued in April 1976, identified many deficiencies in the existing sampling systems and made recommendations for corrective action. The objectives of this experimental evaluation of those sampling systems were as follows: Characterize the radioactive aerosols in the stack effluents; Develop a tracer aerosol technique for validating particulate effluent sampling system performance; Evaluate the performance of the existing routine sampling systems and their compliance with the sponsor's criteria; and Recommend corrective action where required. The tracer aerosol approach to sampler evaluation was chosen because the low concentrations of radioactive particulates in the effluents would otherwise require much longer sampling times and thus more time to complete this evaluation. The following report describes the sampling systems that are the subject of this study and then details the experiments performed. The results are then presented and discussed. Much of the raw and finished data are included in the appendices

Accountability in district nursing practice: key concepts.

Science.gov (United States)

Griffith, Richard

2015-03-01

Public trust and confidence in district nurses is essential to the nurse-patient relationship that underpins effective care and treatment. That trust and confidence has even greater focus for district nurses who care for patients in their own homes. Those patients need to be able to count on the professionalism and probity of their district nurses. The professionalism and probity of district nurses is based on their accountability, which protects the public by imposing standards on district nurses and holds them answerable for their acts and omissions. This is the first of a series of articles on accountability in district nursing practice to mark the introduction of the revised Nursing and Midwifery Code on the 31 March 2015. This month's article considers the key concepts of accountability.

Interim district energy implementation

Energy Technology Data Exchange (ETDEWEB)

Fearnley, R.; Susak, W. [City of Vancouver, BC (Canada); Johnstone, I. [BCG Services Inc., Vancouver, BC (Canada)

2001-07-01

The concept of district energy was introduced in the City of North Vancouver, a city of 45,000, in 1997. A preliminary study was completed in 1997, followed by a tour of some district energy facilities in Finland in the same year. In 1999 a large district energy study was completed by a consultant. The study indicated the need for an investment of $15 million to implement district heating in the City. Lack of sufficient financial resources and immediately connectable heat load, the project was considered a non-starter. Some of the other factors leading to shelving the project included no current significant pricing advantages over competing energy sources and no current opportunity for cogeneration, given the low price that BC Hydro is willing to pay for independently produced power. The project, although shelved for the moment, has not been discarded. Planning and exploration are continuing, aided by the City's commitment to energy efficiency and conservation, its long term planning horizon and its significant influence over the development of some prime real estate.

Energy supply and urban planning projects: Analysing tensions around district heating provision in a French eco-district

International Nuclear Information System (INIS)

Gabillet, Pauline

2015-01-01

Through the analysis of energy supply choices, this article explores the way in which energy priorities and their climate-related features are incorporated into urban public policy. These choices must take account of different factors, as is the case with district heating, which is justified as a vehicle of renewable energy while subject to pressure in eco-districts because its techno-economic balances are destabilised by falls in demand. Our study focuses particularly on the city of Metz (France), which has chosen district heating as the primary source for provision for the municipal area and for its first eco-district. We analyse the tensions within these choices, with particular attention to the way in which they are negotiated inside municipal departments and with the local energy operator. This enables us to explore the tensions in defining the scale that governs decisions and the linkages between energy-related and urban priorities. - Highlights: • Analyses of tensions in the choice of energy supplies for eco-districts. •District heating networks can be vehicles of renewable energy. • District heating networks are threatened by drops in energy consumption. • Energy supply issues oppose urban planning and energy policy in municipal departments. • Technical and financial adjustments can be made by the municipality to justify its energy choices

Full Text Available The purpose of this research is to provide feasibility analysis of a long-term sustainable development concept for district heating based on wood residues. In this paper, the experimental study has been conducted starting from the data collected by field researches in municipality of Trstenik (town in Serbia with district heating system currently based on heavy fuel oil and lignite. Using the method of Financial Cost-Benefit Analysis, this study evaluates financial efficiency of investment in district heating plant based on wood residues and energy savings in district heating system. Findings show that such investment could be profitable from the financial point of view: Net Present Value of investment is positive, Financial Rate of Return is high (30.69%, and the pay-back period is relatively favourable (7 years. Moreover, the presented SWOT indicates that there are realistic prospects of implementation of district heating based on wood residues. However, this does not mean everything will go smoothly and easily, keeping in mind a number of challenges that each new concept of district heating contains immanently. Nevertheless, the results of this research could provide useful inputs for the decision makers when selecting appropriate models for improving performance of municipal district heating systems.

Energy, economy and exergy evaluations of the solutions for supplying domestic hot water from low-temperature district heating in Denmark

International Nuclear Information System (INIS)

Yang, Xiaochen; Li, Hongwei; Svendsen, Svend

2016-01-01

Highlights: • Provided domestic hot water configurations for low-temperature district heating. • Various building typologies and district heating supply temperatures were included. • Different scenarios were evaluated from the energy, economy and exergy aspects. • The benefits of lower return temperature to district heating were investigated. - Abstract: District heating in Denmark is going through the transition from 3rd generation (80/40 °C) to 4th generation (50–55 °C/25 °C) systems in preparation for district heating based completely on renewable fuels by 2035. However, concern about Legionella growth and reduced comfort with low-temperature domestic hot water supply may be discouraging the implementation of low-temperature district heating. Aimed at providing possible solutions, this study modelled various proposals for district heating systems with supply temperatures of 65 °C, 50 °C and 35 °C and for two different building topologies. Evaluation models were built to investigate the energy, economy and exergy performances of the proposed domestic hot water systems in various configurations. The configurations of the devised domestic hot water substations were optimised to fit well with both low and ultra-low-temperature district heating and to reduce the return temperature to district heating. The benefits of lower return temperatures were also analysed compared with the current district heating situation. The evaluation results show that the decentralized substation system with instantaneous heat exchanger unit performed better under the 65 °C and 50 °C district heating scenarios, while the individual micro tank solution consumed less energy and cost less in the 35 °C district heating scenario.

Full Text Available The Lao PDR (Laos is one of the least developed countries in Asia with an estimated 25% of the population living in poverty. It is the habitat of some highly venomous snakes and the majority of the population earns their living from agricultural activities. Under these circumstances the incidence of snakebites is expected to be high.Two cross-sectional, community-based surveys were performed in Champone and Phin district, Savannakhet province, Lao PDR to estimate snakebite incidence. Multistage random sampling was used. In the first stage approximately 40% of all villages in each district were randomly selected. In the second stage 33% of all households in each village were randomly chosen. Members of the selected households were interviewed about snakebites during the previous 12 months.Thirty-five of 9856 interviewees reported a snakebite in a 12 month period in Champone district and 79 of 7150 interviewees in Phin district. The estimated incidence is 355 snakebites per 100,000 persons per year and 1105 per 100,000 in Champone and Phin district respectively. All snakebite victims received treatment by traditional healers or self-treatment at home and nobody went to a hospital. Incidence of snakebites, calculated on the basis of hospital records of 14 district hospitals and Savannakhet provincial hospital, ranged from 3 to 14 cases per 100,000 persons per year between 2012 and 2014.Incidence of snakebites is high in rural communities in Laos with significant regional differences. Poverty most likely contributes significantly to the higher number of snakebites in Phin district. Hospital statistics profoundly underestimates snakebite incidence, because the majority of snakebite victims receive only treatment by traditional healers or self-treatment in their village. There is an urgent need to train medical staff and students in management of snakebite patients and make snake antivenom available to cope effectively with this important public

District heating in Flensburg

Energy Technology Data Exchange (ETDEWEB)

Prinz, W.

1981-01-01

The majority of our population, but also of our authorities, are still skeptical or even disapproving towards district heating. The reasons of this negative attitude are partly psychological - e.g. the individualism of the Swiss and their dislike for too centralised structures and ''forced connections'' - but also the existence of finished gas supply networks and the fear of considerable pre-investments and torn streets over years. The following article - held as a speech on the information meeting ''District heating and the possible contribution of nuclear energy'' organised by the Swiss Association for Atomic Energy in Bern shows a practical problem solving at the example of the district heating in Flensburg and deals with these questions.

Shortage of energy increases profitability of district heating

International Nuclear Information System (INIS)

2003-01-01

Increased demand will cause the price of district heating to increase, but not to the level of the price of electricity. The cheapest heating alternative in Denmark, Norway and Sweden is district heating. In Norway, district heating is developed primarily for commercial buildings and housing cooperatives. Thirty per cent of all buildings under construction are prepared for district heating and the percentage will increase strongly in the coming time. The total net production of district heating in Norway in 2001 was 2000 GWh, which is only a small part of the total potential for district heating

Powell, Brian F.; Halvorson, William L.; Schmidt, Cecilia A.

2007-01-01

This report summarizes the results of the first comprehensive inventory of plants and vertebrates at the Tucson Mountain District (TMD) of Saguaro National Park, Arizona. From 2001 to 2003 we surveyed for vascular plants and vertebrates (amphibians, reptiles, birds, and mammals) at the district to document the presence of species within its boundaries. Park staff also carried out extensive infrared-triggered camera work for medium and large mammals from 2002-2005 and results from that effort are reported here. Our spatial sampling design for all taxa employed a combination of random and nonrandom survey sites. Survey effort was greatest for medium and large mammals and herpetofauna. Because we used repeatable study designs and standardized field methods, these inventories can serve as the first step in a biological monitoring program for the district. We also provide an overview of previous survey efforts in the district. We use data from our inventory and other surveys to compile species lists and to assess inventory completeness. The survey effort for herpetofauna, birds, and medium and large mammals was the most comprehensive ever undertaken in the district. We recorded a total of 320 plant and vertebrate species, including 21 species not previously found in the district (Table 1). Based on a review of our inventory and past research at the district, there have been a total of 723 species of plants and vertebrates found there. We believe inventories for most taxonomic groups are nearly complete. Based on our surveys, we believe the native plant and vertebrate community compositions of the district are relatively intact, though some species loss has occurred and threats are increasing, particularly to herpetofauna and larger mammals. Of particular note is the relatively small number of non-native species and their low abundance in the district, which is in contrast to many nearby natural areas. Rapidly expanding development on the west, north, and east sides of

Full Text Available This study aimed to investigate the influence of reciprocal interactions in the family on academic performance among secondary school students in Siaya District. Stratified and purposive sampling techniques were used to select the study participants. The sample comprised of a total of 243 students (154 boys and 89 girls drawn from 27 public coeducational schools in the district.  Data was collected using student questionnaires. The researchers’ judgment of the representativeness of the items in the questionnaire to the study topic was used to determine content validity of the instrument while Cronbach’s alpha coefficient was used to ascertain validity and reliability of the instrument. Linear regression analysis and one way Analysis of Variance were used to analyze data. The results revealed significant relationship between reciprocal interactions in the family and academic performance of students. There was positive correlation between parental expectation, autonomy granting, cross-sex behaviour and students’ academic performance. Siblings’ sex dyads and birth order were also found to correlate with students’ academic performance. The findings may be used by policy makers to sensitize parents and students on the significance of specific interactions in the family on academic performance.

Maregesi, Sheila M; Messo, Charles W; Mathias, Juma

2017-01-01

This study aimed at documenting products used as traditional eye medicine (TEM) in Misungwi district, Tanzania, and performing preliminary analysis on safety status. Ethnomedical study was conducted in Misungwi district. Information was sourced by face-to-face interview with traditional healers, traditional medicine vendors, and knowledgeable people guided by a well-structured questionnaire. Safety was evaluated by determining pH using pH meter and mineral analysis using the Delta, Portable X-ray fluorescence equipment, and qualitative chemical tests. A total of 23 TEM products were recorded from botanical (79%) and zoological (21%) sources including animal excreta. Liquid preparation ranked highest among dosage forms. Safety evaluation showed that only one product possessed the pH value of 7.4 as recommended for topical ophthalmic medicines. Fourteen minerals were detected and quantified in three samples; some of these minerals are known for their negative effects to the eyes, of medical interest is strontium used for the management of benign eye tumors. Information providers were unaware of health risks associated with the use of TEM. This study has revealed the common use of TEM in Misungwi district. The majority of the products are from the botanical source. Although literature provides supporting data for the application to some of the recorded TEM, safety evaluation by pH and mineral analysis in this study have indicated possible ophthalmological medical problems that could result from using such products. Extensive scientific studies including animal experiments and identification of bioactive compounds are essential to develop safe TEMs.

Full Text Available Good life cannot be achieved without having good living conditions. Living conditions are the most important factor in people’s lives. In the Beijing Fengtai District, the second largest district in Beijing (area: 306 km2; population: 1,360,000, there were three types of housing that had been chosen for the survey: apartment, traditional house and terrace house. The objectives contained in this research are to study residents’ perspectives and preferences of future living conditions in Beijing’s Fengtai District. Also, the study is to know the government’s opinion on living conditions and for future housing development. The close-ended questionnaire with the five-point Likert scale is used as the study methodology. It includes eight attributes of living conditions, residents’ opinion on living conditions now and preferences in the future. A random sample was selected in order to choose the potential respondents for the survey purposes. Additionally, residents’ positive satisfaction can also produce the high return rate to housing development. Based on this research, residents’ in Beijing Fengtai District showed their high aspirations regarding future housing and desired good living conditions. Therefore, to improve the living conditions of their houses, the government, developers and residents should cooperate together to contribute to housing development in the Beijing Fengtai District. Finally, it is hoped that this research could give some suggestions to the other areas in housing development.

Rural district hospitals - essential cogs in the district health system - and primary healthcare re-engineering.

2015-06-01

The re-engineering of primary healthcare (PHC) is regarded as an essential precursor to the implementation of National Health Insurance in South Africa, but improvements in the provision of PHC services have been patchy. The authors contend that the role of well- functioning rural district hospitals as a hub from which PHC services can be most efficiently managed has been underestimated, and that the management of district hospitals and PHC clinics need to be co-located at the level of the rural district hospital, to allow for proper integration of care and effective healthcare provision.

STATISTICAL EVALUATION OF SMALL SCALE MIXING DEMONSTRATION SAMPLING AND BATCH TRANSFER PERFORMANCE - 12093

Energy Technology Data Exchange (ETDEWEB)

GREER DA; THIEN MG

2012-01-12

The ability to effectively mix, sample, certify, and deliver consistent batches of High Level Waste (HLW) feed from the Hanford Double Shell Tanks (DST) to the Waste Treatment and Immobilization Plant (WTP) presents a significant mission risk with potential to impact mission length and the quantity of HLW glass produced. DOE's Tank Operations Contractor, Washington River Protection Solutions (WRPS) has previously presented the results of mixing performance in two different sizes of small scale DSTs to support scale up estimates of full scale DST mixing performance. Currently, sufficient sampling of DSTs is one of the largest programmatic risks that could prevent timely delivery of high level waste to the WTP. WRPS has performed small scale mixing and sampling demonstrations to study the ability to sufficiently sample the tanks. The statistical evaluation of the demonstration results which lead to the conclusion that the two scales of small DST are behaving similarly and that full scale performance is predictable will be presented. This work is essential to reduce the risk of requiring a new dedicated feed sampling facility and will guide future optimization work to ensure the waste feed delivery mission will be accomplished successfully. This paper will focus on the analytical data collected from mixing, sampling, and batch transfer testing from the small scale mixing demonstration tanks and how those data are being interpreted to begin to understand the relationship between samples taken prior to transfer and samples from the subsequent batches transferred. An overview of the types of data collected and examples of typical raw data will be provided. The paper will then discuss the processing and manipulation of the data which is necessary to begin evaluating sampling and batch transfer performance. This discussion will also include the evaluation of the analytical measurement capability with regard to the simulant material used in the demonstration tests. The

Probability sampling design in ethnobotanical surveys of medicinal plants

2012-07-01

Full Text Available Non-probability sampling design can be used in ethnobotanical surveys of medicinal plants. However, this method does not allow statistical inferences to be made from the data generated. The aim of this paper is to present a probability sampling design that is applicable in ethnobotanical studies of medicinal plants. The sampling design employed in the research titled "Ethnobotanical knowledge of medicinal plants used by traditional communities of Nossa Senhora Aparecida do Chumbo district (NSACD, Poconé, Mato Grosso, Brazil" was used as a case study. Probability sampling methods (simple random and stratified sampling were used in this study. In order to determine the sample size, the following data were considered: population size (N of 1179 families; confidence coefficient, 95%; sample error (d, 0.05; and a proportion (p, 0.5. The application of this sampling method resulted in a sample size (n of at least 290 families in the district. The present study concludes that probability sampling methods necessarily have to be employed in ethnobotanical studies of medicinal plants, particularly where statistical inferences have to be made using data obtained. This can be achieved by applying different existing probability sampling methods, or better still, a combination of such methods.

This research provides the initial information to local sanitation to the distribution pattern of E. coli within the dense residential area.

Energy Assessment of Automated Mobility Districts

Energy Technology Data Exchange (ETDEWEB)

Chen, Yuche [National Renewable Energy Laboratory (NREL), Golden, CO (United States)

2017-08-03

Automated vehicles (AVs) are increasingly being discussed as the basis for on-demand mobility services, introducing a new paradigm in which a fleet of AVs displace private automobiles for day-to-day travel in dense activity districts. This project examines such a concept to displace privately owned automobiles within a region containing dense activity generators (jobs, retail, entertainment, etc.), referred to as an automated mobility district (AMDs). The project reviews several such districts including airport, college campuses, business parks, downtown urban cores, and military bases, with examples of previous attempts to meet the mobility needs apart from private automobiles, some with automated technology and others with more traditional transit based solutions. The issues and benefits of AMDs are framed within the perspective of intra-district, inter-district, and border issues, and the requirements for a modeling framework are identified to adequately reflect the breadth of mobility, energy, and emissions impact anticipated with AMDs.

The Influence of Scale on School Performance

Directory of Open Access Journals (Sweden)

Robert Bickel

2000-05-01

Full Text Available In this study, we investigate the joint influence of school and district size on school performance among schools with eighth grades (n=367 and schools with eleventh grades in Georgia (n=298. Schools are the unit of analysis in this study because schools are increasingly the unit on which states fix the responsibility to be accountable. The methodology further develops investigations along the line of evidence suggesting that the influence of size is contingent on socioeconomic status (SES. All previous studies have used a single-level regression model (i.e., schools or districts. This study confronts the issue of cross-level interaction of SES and size (i.e., schools and districts with a single-equation-relative-effects model to interpret the joint influence of school and district size on school performance (i.e., the dependent variable is a school-level variable. It also tests the equity of school-level outcomes jointly by school and district size. Georgia was chosen for study because previous single-level analysis there had revealed no influence of district size on performance (measured at the district level. Findings from this study show substantial cross-level influences of school and district size at the 8th grade, and weaker influences at the 11th grade. The equity effects, however, are strong at both grade levels and show a distinctive pattern of size interactions. Results are interpreted to draw implications for a "structuralist" view of school and district restructuring, with particular concern for schooling to serve impoverished communities. The authors argue the importance of a notion of "scaling" in the system of schooling, advocating the particular need to create smaller districts as well as smaller schools as a route to both school excellence and equity of school outcomes.

A good year for district heating

In Norway, high prices on electric power have caused economic progress for the district heating companies. The price of district heating is determined by the prices of power and fuel oil. However, the government wants to remove the tax on electricity to the industry, which is the district heating companies' major group of customers, along with public buildings. This is likely to entail a great loss of income

District heating in sequential energy supply

2012-01-01

Highlights: ► European excess heat recovery and utilisation by district heat distribution. ► Heat recovery in district heating systems – a structural energy efficiency measure. ► Introduction of new theoretical concepts to express excess heat recovery. ► Fourfold potential for excess heat utilisation in EU27 compared to current levels. ► Large scale excess heat recovery – a collaborative challenge for future Europe. -- Abstract: Increased recovery of excess heat from thermal power generation and industrial processes has great potential to reduce primary energy demands in EU27. In this study, current excess heat utilisation levels by means of district heat distribution are assessed and expressed by concepts such as recovery efficiency, heat recovery rate, and heat utilisation rate. For two chosen excess heat activities, current average EU27 heat recovery levels are compared to currently best Member State practices, whereby future potentials of European excess heat recovery and utilisation are estimated. The principle of sequential energy supply is elaborated to capture the conceptual idea of excess heat recovery in district heating systems as a structural and organisational energy efficiency measure. The general conditions discussed concerning expansion of heat recovery into district heating systems include infrastructure investments in district heating networks, collaboration agreements, maintained value chains, policy support, world market energy prices, allocation of synergy benefits, and local initiatives. The main conclusion from this study is that a future fourfold increase of current EU27 excess heat utilisation by means of district heat distribution to residential and service sectors is conceived as plausible if applying best Member State practice. This estimation is higher than the threefold increase with respect to direct feasible distribution costs estimated by the same authors in a previous study. Hence, no direct barriers appear with

little increase in the potential for discretion at the district level in managing public funds for health - this is likely to be an important reason for the lack of improvement in publicly funded health services. Key decisions about money are still made by the central government, and no one is held accountable for the performance of the sector - the district blames the center and the central ministries (and their ministers) are not accountable to district populations.

Full Text Available Voluntary medical male circumcision (VMMC reduces the acquisition of human immunodeficiency virus (HIV in heterosexual men by up to 60%. One HIV infection is averted for every 5 to 15 VMMCs. To conduct VMMCs in large populations, large numbers of trained healthcare professionals are needed. Countries in Sub-Saharan Africa have a high burden of HIV and a shortage of healthcare professionals, creating a healthcare conundrum. To bridge this gap, South Africa launched a new cadre of mid-level medical worker called Clinical Associates (CA. We assessed the ability of CAs to perform circumcisions of adequate quality and their subsequent usefulness to meet the demands of VMMCs in a population with a high HIV burden.We conducted a retrospective analysis, reviewing patient files (n = 4850 of surgical VMMCs conducted over a 16-month period. Patient files were sourced from clinics and hospitals that provided free VMMCs in Tshwane district in South Africa.Clinical associates performed 88.66% of the circumcisions and doctors performed the remaining 11.34% (p < 0.001. The number of adverse events did not differ between the two groups. Data on intra-operative adverse events were available for 4 738 patients. Of these, 341 (7.2% experienced intra-operative adverse events. For the whole sample, 44 (8.1%, n = 543 adverse events occurred during circumcisions done by doctors and 297 (7.1%, n = 4195 occurred during circumcisions done by CAs (p = 0.385. Clinical associates performed circumcisions in shorter times (duration: 14.63 minutes compared to doctors (duration: 15.25 minutes, t = -7.46; p < 0.001. Recorded pain, bleeding, swelling, infection and wound destruction did not differ between clients circumcised by CAs and doctors. This study is limited by the use of data from a single district.Clinical associates contribute to the demands for high numbers of VMMCs in Tshwane district, South Africa.

Full Text Available Historically the western sahelian dry regions of Mali are known to be highly endemic for cutaneous leishmaniasis (CL caused by Leishmania major, while cases are rarely reported from the Southern savanna forest of the country. Here, we report baseline prevalence of CL infection in 3 ecologically distinct districts of Mali (dry sahelian, north savanna and southern savanna forest areas. We screened 195 to 250 subjects from 50 to 60 randomly selected households in each of the 6 villages (four from the western sahelian district of Diema in Kayes region, one from the central district of Kolokani and one from the southern savanna district of Kolodieba, region of Sikasso. The screening consisted of: 1] A Leishmanin Skin Test (LST for detection of exposure to Leishmania parasites; 2] clinical examination of suspected lesions, followed by validation with PCR and 3] finger prick blood sample to determine antibody levels to sand fly saliva. LST positivity was higher in the western district of Diema (49.9% than in Kolokani (24.9% and was much lower in Kolondieba (2.6%. LST positivity increased with age rising from 13.8% to 88% in Diema for age groups 2-5 years and 41-65 years, respectively. All eight PCR-confirmed L. major CL cases were diagnosed in subjects below 18 years of age and all were residents of the district of Diema. Exposure to sand fly bites, measured by anti-saliva antibody titers, was comparable in individuals living in all three districts. However, antibody titers were significantly higher in LST positive individuals (P<0.0001. In conclusion, CL transmission remains active in the western region of Mali where lesions were mainly prevalent among children under 18 years old. LST positivity correlated to higher levels of antibodies to sand fly salivary proteins, suggesting their potential as a risk marker for CL acquisition in Mali.

The situation of district heating, district cooling and energy supply in Hungary

International Nuclear Information System (INIS)

Sigmond, Gy.

2009-01-01

District heating represents with 650.000 heated dwellings approximately 15% of the Hungarian residential heating market. Since 1990 there is stagnation at the number of connected dwellings because erection of large settlements with prefab buildings has been stopped, and latter ones represent more than 75% of the dwelling heating market. During the same period, residential heat demand shrunk by 33%, because metering of hot water consumption resulted in changing consumer habits, and because of slowly but step by step refurbishment of buildings and heating systems. In Hungary district heating is present in all large and most of the medium size cities, in 92 cities together. Out of them, there is also a single village with a local district heating system, which heats more than 60% of cottages. The capacity os systems is spreading to a large extent. Approximately 36-36% of all heated dwellings are in Budapest and in 10 large cities in the country, while 148 of the total 202 systems have less than 10 MW capacities. In the fuel structure of district heating it is characteristic the overwhelming role of natural gas consumption, which has exceeded 80% already. Only a few numbers of heating power plants are fuelled by crown coal. The use of renewables is growing continuous, but, together with waste and waste energy, it amounts merely 8% of the total fuel use. Oil consumption is negligible. Currently the most promising DH-market is the service sector (public buildings and commercial consumers). DH-companies can sell their surplus supply capacities on the competitive market. Residential market can be preserved only with better legal conditions and with improving of demand side management. The industrial heat market can be gained when the erection of new power plants will be harmonized with industrial development in the frame of territorial planning. District cooling is just at the beginning in Hungary. Many new commercial and office buildings are erected with air conditioning

The Role of School District Science Coordinators in the District-Wide Appropriation of an Online Resource Discovery and Sharing Tool for Teachers

2014-06-01

When introducing and implementing a new technology for science teachers within a school district, we must consider not only the end users but also the roles and influence district personnel have on the eventual appropriation of that technology. School districts are, by their nature, complex systems with multiple individuals at different levels in the organization who are involved in supporting and providing instruction. Varying levels of support for new technologies between district coordinators and teachers can sometimes lead to counterintuitive outcomes. In this article, we examine the role of the district science coordinator in five school districts that participated in the implementation of an online resource discovery and sharing tool for Earth science teachers. Using a qualitative approach, we conducted and coded interviews with district coordinators and teachers to examine the varied responsibilities associated with the district coordinator and to infer the relationships that were developed and perceived by teachers. We then examine and discuss two cases that illustrate how those relationships could have influenced how the tool was adopted and used to differing degrees in the two districts. Specifically, the district that had high support for online resource use from its coordinator appeared to have the lowest level of tool use, and the district with much less visible support from its coordinator had the highest level of tool use. We explain this difference in terms of how the coordinator's promotion of teacher autonomy took distinctly different forms at those two districts.

2015-07-01

Full Text Available In this study, five numerical Weibull distribution methods, namely, the maximum likelihood method, the modified maximum likelihood method (MLM, the energy pattern factor method (EPF, the graphical method (GM, and the empirical method (EM were explored using hourly synoptic data collected from 1985 to 2013 in the district of Maroua in Cameroon. The performance analysis revealed that the MLM was the most accurate model followed by the EPF and the GM. Furthermore, the comparison between the wind speed standard deviation predicted by the proposed models and the measured data showed that the MLM has a smaller relative error of -3.33% on average compared to -11.67% on average for the EPF and -8.86% on average for the GM. As a result, the MLM was precisely recommended to estimate the scale and shape parameters for an accurate and efficient wind energy potential evaluation.

Doctors especially house officers are under a great deal of stress related to a variety of occupational stressors. Occupational stressors contribute to organizational inefficiency, high staff turnover, absenteeism due to sickness, decreased quality, and quantity of practice, increased costs of health care, and decreased job satisfaction. One of the organizational outcomes that affected by occupational stress is job performance. The purpose of the present study was to investigate the effect of job stress on job performance. The universe of the study is District Abbottabad and the complete population of house officers was targeted which were present at that time were 55. The data obtained through questionnaire was analyzed using the statistical methods including descriptive statistics, Spearman's correlation and multiple regression. The analysis showed strong support for the hypothesis that there is an inverse relationship between job stress and job performance indicating that there is high job stress in the house officers, resulting in low job performance. Correct stress management should start from improved health and good intrapersonal relationships. The prevention and management of workplace stress requires organizational level interventions, because it is the organization that creates the stress. Success in managing and preventing stress will depend on the culture in the organization. A culture of openness and understanding, rather than of criticism, is essential. Those house officers who had high level of job stress had low job performance. All the factors affected male house officers more than the female house officers.

Madsen, Wendy

2013-06-01

The history of district nursing in Australia explored in this paper reveals a continuity in the essential values held by district nurses for over a century. These nurses practised holistic, family-centred nursing from the very origins of district nursing service. The events surrounding the establishment of Community Health Centres in the 1970s challenged district nurses to reconsider their role, while at the same time reconfirming their essential ethos. These values that underpinned district nursing practice and challenges to these values are examined in this paper.

Performance investigation of the Turkish geothermal district heating systems (GDHSs). Paper no. IGEC-1-066

Ozgener, L.; Hepbasli, A.; Dincer, I.

2005-01-01

Various energy and exergy modeling techniques have been used by many investigators for energy-utilization assessments to minimize losses and maximize energy savings and hence financial savings. Furthermore, performance indices are employed to detect and to evaluate quantitatively the causes of the thermodynamic imperfection of the process under consideration such as exergy analysis. The present study evaluates the performances of the two geothermal district heating systems (GDHSs) installed in Turkey. The GDHSs considered are the Balcova GDHS in Izmir and Salihli GDHS in Manisa, while the exergetic improvement potential (ExIP) and specific exergy index (SExI) are used for the modeling of the entire systems and their essential components for performance evaluations and comparisons as well as possible energy and exergy efficiency improvements. The SExI is found to be 0.07 and 0.049 for the Balcova and Salihli GDHSs, respectively, representing that Balcova and Salihli geothermal fields fall into the medium and low quality geothermal resources according to the Lee's classification, respectively. The values for the ExIP are also obtained as follows: For the BGDHS with thirteen plate-type heat exchangers, fourth heat exchanger has the largest ExIP rate as 69.96 kW, followed by the first, second, and third heat exchangers at 20.07, 11.71, and 4.05 kW capacities, respectively, with the remaining ones under 3 kW, which does not present much potential for improvement. For the SGDHS, the ExIP rate is found to be 106.04 kW for the plate-type heat exchanger. On the other hand, in order to improve the system efficiency, water leaks in the distribution network should be prevented. (author)

Cognitive potential and its predictors in children from a rural district of pakistan

International Nuclear Information System (INIS)

Gilani, I.

2017-01-01

Effective interventions are available to reduce cognitive deficit currently estimated to affect more than 200 million children under 5 years of age in developing countries. However, developing world's investment is negligible in this regard mainly because of non-existent global indicators to monitor progress with respect to the childhood cognitive development. Intelligence Quotient (IQ) or Full Scale Intelligence Quotient (FSIQ) is an indicator of the cognitive development. This study was designed to assess cognitive potential of 6-7 years old children from a rural district of Pakistan by calculating their FSIQ. Predictors of the FSIQ were also determined. Method: This cross-sectional research was carried out in 40 rural Union Councils (UCs) of 2 sub-districts in district Rawalpindi utilizing simple random sampling technique. Wechsler Pre-school and Primary Scale of Intelligence (WPPSI-IV) was administered to 6-7 years old children (n=300) for measuring their FSIQ. Results: FSIQ of rural Pakistani children, relative to the normative sample, was found to be in the category of low-average. Findings of multiple regression analysis concluded grade/class of the child as the most influential predictor of the FSIQ followed by the level of mother's and then father's education. Conclusion: FSIQ of the rural Pakistani children, relative to the normative sample, was found to be in the category of low-average. Predictors of the FSIQ, seen in this research, were school grades and non-educated parents of the children warranting future research on the contribution of environmental influences to the variability in cognitive potential.

A district heating substation is a demanding process for fault diagnosis. The process is nonlinear, load conditions of the district heating network change unpredictably and standard instrumentation is designed only for control and local monitoring purposes, not for automated diagnosis. Extra instrumentation means additional cost, which is usually not acceptable to consumers. That is why all conventional methods are not applicable in this environment. The paper presents five different approaches to fault diagnosis. While developing the methods, various kinds of pragmatic aspects and robustness had to be considered in order to achieve practical solutions. The presented methods are: classification of faults using performance indexing, static and physical modelling of process equipment, energy balance of the process, interactive fault tree reasoning and statistical tests. The methods are applied to a control valve, a heat excharger, a mud separating device and the whole process. The developed methods are verified in practice using simulation, simulation or field tests. (orig.) (25 refs.)

High levels of arsenic contamination in drinking water of two villages, Badarpur and Ibrahimabad of district Kasur, central Punjab, Pakistan is reported first time in present studies. Groundwater quality situation was found to be impaired when samples of different rural areas of district Kasur were monitored according to Pakistan Standards and Quality Control Authority (PSQCA) for all significant water quality constituents and analyzed for trace elements, physico-chemical, and microbiological parameters. Out of 35water sources, 97 % were found unsafe and only 3 % of the sources were within safe limits. High concentrations of arsenic, fluoride, and bacteria were found in 91, 74, and 77 % sources of drinking water, respectively. Very high concentrations of arsenic ranging 58-3800 μg/L were found in the water samples obtained from Badarpur and Ibrahimabad. A decrease in water contamination was observed with increase in source depth. The health issues like arsenicosis and skeletal/dental flourosis were observed in the residents of the monitored areas. Drinking water quality conditions of some rural areas of northen and southern districts of Punjab was also analyzed and compared with Kasur district. High levels of nitrates were found in the samples of Islamabad and Rawalpindi, while high levels of arsenic, iron, fluoride, and TDS were found in Bahawalpur district. Graphical abstract ᅟ.

Mapping species distributions with MAXENT using a geographically biased sample of presence data: a performance assessment of methods for correcting sampling bias.

Fourcade, Yoan; Engler, Jan O; Rödder, Dennis; Secondi, Jean

2014-01-01

MAXENT is now a common species distribution modeling (SDM) tool used by conservation practitioners for predicting the distribution of a species from a set of records and environmental predictors. However, datasets of species occurrence used to train the model are often biased in the geographical space because of unequal sampling effort across the study area. This bias may be a source of strong inaccuracy in the resulting model and could lead to incorrect predictions. Although a number of sampling bias correction methods have been proposed, there is no consensual guideline to account for it. We compared here the performance of five methods of bias correction on three datasets of species occurrence: one "virtual" derived from a land cover map, and two actual datasets for a turtle (Chrysemys picta) and a salamander (Plethodon cylindraceus). We subjected these datasets to four types of sampling biases corresponding to potential types of empirical biases. We applied five correction methods to the biased samples and compared the outputs of distribution models to unbiased datasets to assess the overall correction performance of each method. The results revealed that the ability of methods to correct the initial sampling bias varied greatly depending on bias type, bias intensity and species. However, the simple systematic sampling of records consistently ranked among the best performing across the range of conditions tested, whereas other methods performed more poorly in most cases. The strong effect of initial conditions on correction performance highlights the need for further research to develop a step-by-step guideline to account for sampling bias. However, this method seems to be the most efficient in correcting sampling bias and should be advised in most cases.

About the marshallian industrial district and the theory of the contemporary district. A brief critical reconstruction

Directory of Open Access Journals (Sweden)

Giacomo Becattini

2002-01-01

Full Text Available As a departing point, the paper presents the historical genesis of the concept of industrial district focusing on the scientific views of the pioneer of this field, Alfred Marshall. The concept has its origins in the observation of the current industrial reality, mainly of the British one. The purpose is to give an explanation to the difficulties of the classic theory and to study the challenges of the class conflicts. The economic conditions which launched British industrial districts were present, grosso modo, in Italy after the second World War. Some contributions have dealt with the little industrialisation of some Italian regions and using Marshallian thoughts have rediscovered the industrial districts phenomenon. This is the starting point of a high number of scientific contribution in Italy and abroad. Some of these international studies, particularly the ones made by Spanish experts, are quoted. The text analyses the link between districts-made in Italy with the competitive advantages of Italian products in many economic activities (i.e. clothing, shoes, furniture, etc.. Finally, in the third part the paper reviews some new contributions on the industrial district in Italy.

Survey of [i]Toxoplasma gondii [/i]antibodies in meat juice of wild boar ([i]Sus scrofa[/i] in several districts of the Czech Republic

Karol Račka

2015-05-01

Full Text Available Introduction and objective. The aims of the study were: 1 to detect antibodies against T[i]oxoplasma gondii[/i] from wild boar meat; 1 establish seroprevalence of toxoplasmosis in the wild boar population; 3 establish risk factors concerned in higher possible seroprevalence; 4 to estimate the usefulness of meat juice for detection of [i]T. gondii[/i] antibodies in wild boar. Material and methods. Diaphragm meat juice samples from 656 wild boar ([i]Sus scrofa[/i] were collected during the hunting seasons between September 2008 – October 2010 from 9 districts of the Czech Republic. The samples were stratified per age category into 2 groups: piglets (n = 279 and yearlings together with adults (n = 377. The in-house ELISA test was used for the detection of antibodies against [i]T. gondii [/i]from the meat juice samples. Results. Antibodies against [i]T. gondii [/i]were detected by in-house ELISA in 260 of 656 wild boars (40% with 26% prevalence in piglets (72/279 and 50% prevalence in yearlings and adults (188/377. The district total seroprevalences ranged between 32% – 59%, with a significantly higher prevalence in the district of Havlíčkův Brod (59%. Statistically significant differences (p-value < 0.05 were found between 2 age categories, and between 9 districts, with a significant variability in the district of Havlíčkův Brod. Seroprevalence correlated positively with farm density, but without any statistical significance. Conclusion. The obtained results indicate that consumption of raw or undercooked meat from wild boars can carry an important risk of toxoplasma infection. Post mortem detection of antibodies in meat juice samples using ELISA is a useful alternative to blood serum examination. In addition, a diaphragm sample has been well-proven as a matrix sample for the contemporaneous diagnostics of trichinellosis and toxoplasmosis.

The Euganean Hills of North East Italy have long been recognised as an area characterized by a higher than average natural radiation background. This is due to two main reasons: a) primary lithogenic radiation due to rhyolitic and trachytic outcrops, which are "acidic alkaline" magmatic rocks potentially enriched in uranium and thorium; b) secondary sources related to a geothermal field - widely exploited for spa tourism in the area since the Roman age - producing surface release of radon-enriched fluids. Though radioactivity levels in the Euganean district have been often investigated in the past - including recent works aimed at assessing the radiation doses from radon and/or total gamma radiation - no effort has been put so far into producing a thorough assessment linking radiation protection data to geological-structural features (lithology, faults, water, organic matter content, etc.). This work represents the first part of the interdisciplinary project "Geological and geochemical control on Radon occurrence and natural radioactivity in the Euganean Hills district (North-Eastern Italy)", aimed at producing detailed results of the actual radiation levels in connection mainly with lithological parameters. A detailed sampling strategy, based on lithostratigraphy, petrology and mineralogy, has been adopted. The 151 rock samples collected were analyzed by high resolution γ-ray spectrometry with ex situ HPGe detectors. Statistical and geostatistical analyses were performed, and outlier values of U and Th - possibly associated with anomalies in the geological formation - were identified. U, Th and K concentration maps were developed using both the entire database and then again after expunging the outliers; the two were then compared. In all maps the highest values can be associated to trachyte and rhyolite lithologies, and the lowest ones to sedimentary formations.

The ceramic industry is an important area of economic activity in the Ayacucho Region, in particular in the District of Quinua. As a consequence, there is a huge demand for clay to produce ceramic pastes in that region. This paper reports on results concerning the mineralogical characterization of four clayey samples, which were collected MAA and SPQA from the area Pampa de La Quinua with geographic coordinates 13 Degree-Sign 02 Prime 49 Double-Prime S 74 Degree-Sign 08 Prime 03 Double-Prime W, CE1M and CE2M from the Quinua locality 13 Degree-Sign 03 Prime 07 Double-Prime S 74 Degree-Sign 08 Prime 31 Double-Prime W, both in the District of Quinua, Province of Huamanga, Ayacucho, Peru. The chemical and mineralogical characterization of these samples was carried out with powder X-ray diffraction detecting quartz, albite, montmorillonite, kaolinite and glauconite mineral phases, Moessbauer spectroscopy detected iron in kaolinite, glauconite and montmorillonite minerals. Chemical analysis was performed through scanning electron microscopy and energy dispersive X-ray spectroscopy. Data obtained from the combination of these techniques provided relevant information about the morphology, chemical composition, and the mineralogy of samples.

Karimnagar District has consistently achieved highest rates of no-scalpel vasectomy (NSV) in the past decade when compared to state and national rates. This study was conducted to elucidate the underlying causes for higher acceptance of NSV in the district. A community-based, case control study was conducted. Sampling techniques used were purposive and simple random sampling. A semi-structured questionnaire was used to evaluate the socio-demographic, family characteristics, contraceptive history and predictors of contraceptive choice in 116 NSV acceptors and 120 other contraceptive users (OCUs). Postoperative complications and experiences were ascertained in NSV acceptors. Age (χ(2)=11.79, P value = 0.008), literacy (χ(2)=17.95, P value = 0.03), duration of marriage (χ(2)=14.23, P value = 0.008) and number of children (χ(2)=10.45, P value = 0.01) were significant for acceptance of NSV. Among the predictors, method suggested by peer/ health worker (OR = 1.5, P value = 0.01), method does not require regular intervention (OR = 1.3, P value = 0.004) and permanence of the method (OR = 1.2, P value = 0.031) were significant. Acceptors were most satisfied with the shorter duration required to return to work and the most common complication was persistent postoperative pain among 12 (10.34%) of the acceptors. Advocating and implementing family planning is of high significance in view of the population growth in India and drawing from the demographic profile, predictors, pool of trainers and experiences in Karimnagar District, a similar achievement of higher rates of this simple procedure with few complications can be replicated.

Meyer Swanepoel

2014-12-01

Full Text Available Background: In 2007, South Africa made family medicine a new speciality. Family physicians that have trained for this new speciality have been employed in the district health system since 2011. The aim of the present study was to explore the perceptions of district managers on the impact of family physicians on clinical processes, health system performance and health outcomes in the district health system (DHS of the Western Cape. Methods: Nine in-depth interviews were performed: seven with district managers and two with the chief directors of the metropolitan and rural DHS. Interviews were recorded, transcribed and analysed using the ATLAS-ti and the framework method. Results: There was a positive impact on clinical processes for HIV/AIDS, TB, trauma, noncommunicable chronic diseases, mental health, maternal and child health. Health system performance was positively impacted in terms of access, coordination, comprehensiveness and efficiency. An impact on health outcomes was anticipated. The impact was not uniform throughout the province due to different numbers of family physicians and different abilities to function optimally. There was also a perception that the positive impact attributed to family physicians was in the early stages of development. Unanticipated effects included concerns with their roles in management and training of students, as well as tensions with career medical officers. Conclusion: Early feedback from district managers suggests that where family physicians are employed and able to function optimally, they are making a significant impact on health system performance and the quality of clinical processes. In the longer term, this is likely to impact on health outcomes.

The PHMC will provide Low Activity Wastes (LAW) tank wastes for final treatment by a privatization contractor from double-shell feed tanks, 241-AP-102 and 241-AP-104, Concerns about the inability of the baseline ''grab'' sampling to provide large volume samples within time constraints has led to the development of a conceptual sampling system that would be deployed in a feed tank riser, This sampling system will provide large volume, representative samples without the environmental, radiation exposure, and sample volume impacts of the current base-line ''grab'' sampling method. This test plan identifies ''proof-of-principle'' cold tests for the conceptual sampling system using simulant materials. The need for additional testing was identified as a result of completing tests described in the revision test plan document, Revision 1 outlines tests that will evaluate the performance and ability to provide samples that are representative of a tanks' content within a 95 percent confidence interval, to recovery from plugging, to sample supernatant wastes with over 25 wt% solids content, and to evaluate the impact of sampling at different heights within the feed tank. The test plan also identifies operating parameters that will optimize the performance of the sampling system

Smoking among adolescent is a public health concern in Malaysia. Multiple studies on smoking prevalence and its related factors have been conducted in Malaysia, however, they were specific to either urban or rural areas alone. Studies in mixed settlement areas (urban, rural, land development area) had not been intensively investigated. This study reports the prevalence, demographic and factors related to smoking amongst form four students in the district of Kota Tinggi, Johor. A cross-sectional study of 16-year old secondary school students in Kota Tinggi district was conducted using two-stage stratified, proportionate sampling in July 2005. The study instrument used was a validated structured questionnaire on smoking and its related factors. Smoking prevalence was found to be 29.7%. More than 50% of male students were smokers. Prevalence was highest in FELDA (Federal Land Development Authority) settlement areas. Smoking was associated with having a brother or friend who smokes and poor academic performance. The study revealed that smoking prevalence was high, especially among male students in land development schemes. This situation will contribute to high smoking-related health problems in the future if proper preventive measures are not taken accordingly.

District-level variations in childhood immunizations in India: The role of socio-economic factors and health infrastructure.

Rammohan, Anu; Awofeso, Niyi

2015-11-01

Routine childhood immunizations against measles and DPT are part of the World Health Organization's (WHO) Expanded Program on Immunization (EPI) set up in 1974, with the aim of reducing childhood morbidity and mortality. Despite this, immunization rates are sub-optimal in developing countries such as India, with wide heterogeneity observed across districts and socio-economic characteristics. The aim of this paper is to examine district-level variations in the propensity to vaccinate a child in India for measles and DPT3, and analyse the extent to which these immunizations are given age-inappropriately, either prematurely or delayed. The present study uses data from the Indian District Level Household Survey (DLHS-3) collected in 2008, and the final sample contains detailed information on 42157 children aged between 12 and 60 months, across 549 Indian districts for whom we have complete information on immunization history. Our empirical study analyses: (i) the district-level average immunization rates for measles and DPT3, and (ii) the extent to which these immunizations have been given age-appropriately. A key contribution of this paper is that we link the household-level data at the district level to data on availability and proximity to health infrastructure and district-level socio-economic factors. Our results show that after controlling for an array of socio-economic characteristics, across all our models, the district's income per capita is a strong predictor of better immunization outcomes for children. Mother's education level at the district-level has a statistically significant and positive influence on immunization outcomes across all our models. Copyright © 2015 Elsevier Ltd.

Despite recurring outbreaks of cholera in Ghana, very little has been reported on assessments of outbreak response activities undertaken in affected areas. This study assessed the response activities undertaken in two districts, Akatsi District in Volta Region and Komenda-Edina-Eguafo-Abirem (KEEA) Municipal in Central Region during the 2012 cholera epidemic in Ghana. We conducted a retrospective assessment of the events, strengths and weaknesses of the cholera outbreak response activities in the two districts making use of the WHO cholera evaluation tool. Information sources included surveillance and facility records, reports and interviews with relevant health personnel involved in the outbreak response from both district health directorates and health facilities. We collected data on age, sex, area of residence, date of reporting to health facility of cholera cases, district population data and information on the outbreak response activities and performed descriptive analyses of the outbreak data by person, time and place. The cholera outbreak in Akatsi was explosive with a high attack rate (AR) of 374/100,000 and case fatality rate (CFR) of 1.2 % while that in KEEA was on a relatively smaller scale AR of 23/100,000 but with a high case fatality rate of 18.8 %. For both districts, we identified multiple strengths in the response to the outbreak including timely notification of the district health officials which triggered prompt investigation of the suspected outbreak facilitating confirmation of cholera and initiation of public health response activities. Others were coordination of the activities by multi-sectoral committees, instituting water, sanitation and hygiene measures and appropriate case management at health facilities. We also found areas that needed improvement in both districts including incomplete surveillance data, sub-optimal community based surveillance considering the late reporting and the deaths in the community and the inadequate

District managers are playing an increasingly important role in determining the performance of health systems in low- and middle-income countries as a result of decentralization. To assess the effectiveness of interventions to hire, retain and train district health systems managers in low- and middle-income countries. We searched a wide range of international databases, including the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE and EMBASE. We also searched online resources of international agencies, including the World Bank, to find relevant grey literature. Searches were conducted in December 2011. District health systems managers are those persons who are responsible for overseeing the operations of the health system within a defined, subnational geographical area that is designated as a district. Hiring and retention interventions include those that aim to increase the attractiveness of district management positions, as well as those related to hiring and retention processes, such as private contracting. Training interventions include education programs to develop future managers and on-the-job training programs for current managers. To be included, studies needed to use one of the following study designs: randomized controlled trial, nonrandomized controlled trial, controlled before-and-after study, and interrupted time series analysis. We report measures of effect in the same way that the primary study authors have reported them. Due to the varied nature of interventions included in this review we could not pool data across studies. Two studies met our inclusion criteria. The findings of one study conducted in Cambodia provide low quality evidence that private contracts with international nongovernmental organizations (NGOs) for district health systems management ('contracting-in') may improve health care access and utilization. Contracting-in increased use of antenatal care by 28% and use of public facilities by 14%. However, contracting

Buchanan, Donald G.

This study evaluated selected demographic, pre-enrollment, and economic status variables in comparison to college-level performance factors of GPA and course completion ratios for gateway math and science courses. The Transfer and Retention of Urban Community College Students (TRUCCS) project team collected survey and enrollment data for this study in the Los Angeles Community College District (LACCD). The TRUCCS team surveyed over 5,000 students within the nine campus district beginning in the fall of 2000 and spring of 2001 with follow-up data for next several years. This study focused on the math and science courses; established background demographics; evaluated pre-enrollment high school self-reported grades; reviewed high school and college level math courses taken; investigated specific gateway courses of biology, chemistry and physics; and compared them to the overall GPAs and course completion ratios for 4,698 students. This involved the SPSS development of numerous statistical products including the data from frequency distributions, means, cross-tabulations, group statistics t-tests, independent samples t-tests, and one-way ANOVA. Findings revealed demographic and economic relationships of significance for students' performance factors of GPA and course completion ratios. Furthermore, findings revealed significant differences between the gender, age, ethnicity and economic employment relationships. Conclusions and implications for institutions of higher education were documented. Recommendations for dissemination, intervention programs, and future research were also discussed.

2017-10-01

The level of radon concentration has been assessed using the Advanced SMART RnDuo technique in 30 drinking water samples from Jammu district, Jammu and Kashmir, India. The water samples were collected from wells, hand pumps, submersible pumps, and stored waters. The randomly obtained 14 values of radon concentration in water sources using the SMART RnDuo technique have been compared and cross checked by a RAD7 device. A good positive correlation (R = 0.88) has been observed between the two techniques. The overall value of radon concentration in various water sources has ranged from 2.45 to 18.43 Bq L, with a mean value of 8.24 ± 4.04 Bq L, and it agreed well with the recommended limit suggested by the European Commission and UNSCEAR. However, the higher activity of mean radon concentration was found in groundwater drawn from well, hand and submersible pumps as compared to stored water. The total annual effective dose due to radon inhalation and ingestion ranged from 6.69 to 50.31 μSv y with a mean value of 22.48 ± 11.03 μSv y. The total annual effective dose was found to lie within the safe limit (100 μSv y) suggested by WHO. Heavy metal analysis was also carried out in various water sources by using an atomic absorption spectrophotometer (AAS), and the highest value of heavy metals was found mostly in groundwater samples. The obtained results were compared with Indian and International organizations like WHO and the EU Council. Among all the samples, the elemental analysis is not on the exceeding side of the permissible limit.

Malaria is endemic in 13 districts of Bangladesh. A baseline malaria prevalence survey across the endemic districts of Bangladesh was conducted in 2007, when the prevalence was reported around 39.7 per 1000 population. After two rounds of Global Fund to Fight AIDS, Tuberculosis and Malaria (GFATM)-funded intervention by the National Malaria Control Programme (NMCP) and a BRAC-led NGO consortium, a follow-up survey was conducted across the malaria-endemic districts of Bangladesh to measure the change in prevalence rate and in people's knowledge of malaria. The survey was carried out from August to November 2013 in 70 upazilas (sub-districts) of 13 malaria-endemic districts of Bangladesh, following the same multi-stage cluster sampling design and the same number of households enrolled during the baseline prevalence survey in 2007, to collect 9750 randomly selected blood samples. For on-the-spot diagnosis of malaria, a rapid diagnostic test was used. The household head or eldest person available was interviewed using a pre-coded structured questionnaire to collect data on the knowledge and awareness of malaria in the household. Based on a weighted calculation, the overall malaria prevalence was found to be 1.41 per 1000 population. The proportion of Plasmodium falciparum mono-infection was 77.78% while both Plasmodium vivax mono-infection and mixed infection of the two species were found to be 11.11%. Bandarban had the highest prevalence (6.67 per 1000 population). Knowledge of malaria signs, symptoms and mode of transmission were higher in the follow-up survey (97.26%) than the baseline survey. Use of bed nets for prevention of malaria was found to be high (90.15%) at respondent level. People's knowledge of selected parameters increased significantly during the follow-up survey compared to the baseline survey conducted in 2007. A reduced prevalence rate of malaria and increased level of knowledge were observed in the present malaria prevalence survey in Bangladesh.

Assessment of nurses’ cardiopulmonary resuscitation knowledge and skills within three district hospitals in Botswana

Science.gov (United States)

2018-01-01

Background Nurses are usually the first to identify the need for and initiate cardiopulmonary resuscitation (CPR) on patients with cardiopulmonary arrest in the hospital setting. Cardiopulmonary resuscitation has been shown to reduce in-hospital deaths when received from adequately trained health care professionals. Aim We aimed to investigate nurses’ retention of CPR knowledge and skills at district hospitals in Botswana. Methods A quantitative, quasi-experimental study was conducted at three hospitals in Botswana. A pre-test, intervention, post-test, and a re-test after 6 months were utilised to determine the retention of CPR knowledge and skills. Non-probability, convenience sampling technique was used to select 154 nurses. The sequences of the test were consistent with the American Heart Association’s 2010 basic life support (BLS) guidelines for health care providers. Data were analysed to compare performance over time. Results This study showed markedly deficient CPR knowledge and skills among registered nurses in the three district hospitals. The pre-test knowledge average score (48%) indicated that the nurses did not know the majority of the BLS steps. Only 85 nurses participated in the re-evaluation test at 6 months. While a 26.4% increase was observed in the immediate post-test score compared with the pre-test, the performance of the available participants dropped by 14.5% in the re-test 6 months after the post-test. Conclusion Poor CPR knowledge and skills among registered nurses may impede the survival and management of cardiac arrest victims. Employers and nursing professional bodies in Botswana should encourage and monitor regular CPR refresher courses. PMID:29781687

 Nurses are usually the first to identify the need for and initiate cardiopulmonary resuscitation (CPR) on patients with cardiopulmonary arrest in the hospital setting. Cardiopulmonary resuscitation has been shown to reduce in-hospital deaths when received from adequately trained health care professionals.  We aimed to investigate nurses' retention of CPR knowledge and skills at district hospitals in Botswana.  A quantitative, quasi-experimental study was conducted at three hospitals in Botswana. A pre-test, intervention, post-test, and a re-test after 6 months were utilised to determine the retention of CPR knowledge and skills. Non-probability, convenience sampling technique was used to select 154 nurses.The sequences of the test were consistent with the American Heart Association's 2010 basic life support (BLS) guidelines for health care providers. Data were analysed to compare performance over time.  This study showed markedly deficient CPR knowledge and skills among registered nurses in the three district hospitals.

The ceramic industry is an important area of economic activity in the Ayacucho Region, in particular in the District of Quinua. As a consequence, there is a huge demand for clay to produce ceramic pastes in that region. This paper reports on results concerning the mineralogical characterization of four clayey samples, which were collected MAA and SPQA from the area Pampa de La Quinua with geographic coordinates 13° 02' 49″ S 74° 08' 03″ W, CE1M and CE2M from the Quinua locality 13° 03' 07″ S 74° 08' 31″ W, both in the District of Quinua, Province of Huamanga, Ayacucho, Peru. The chemical and mineralogical characterization of these samples was carried out with powder X-ray diffraction detecting quartz, albite, montmorillonite, kaolinite and glauconite mineral phases, Mössbauer spectroscopy detected iron in kaolinite, glauconite and montmorillonite minerals. Chemical analysis was performed through scanning electron microscopy and energy dispersive X-ray spectroscopy. Data obtained from the combination of these techniques provided relevant information about the morphology, chemical composition, and the mineralogy of samples.

Full Text Available A carbon dioxide emission on peatland under oil palm plantation was highly varied due to many factors involved. The objectives of the research were to evaluate the effect of sampling distance from center of oil palm tree on Carbon dioxide flux, and to study the factors that cause variability of carbon dioxide flux on peatland under oil palm plantation. The study was conducted on peatland at Arang-Arang Village, Kumpek Ulu Sub-District, Muaro Jambi District, Jambi Province, on six-years old oil palm plantation. The study was conducted in the form of observational exploratory. Emission measurements were performed on 5 selected oil palm trees at points within 100, 150, 200, 250, 300, 350, and 400 cm from the center of trunk. Carbon dioxide flux was measured using (IRGA, Li-COR 820. The results showed that there was significant correlation between the distance of sampling from center of oil palm tree and Carbon dioxide flux. The farther distance from the tree, the more decreased of Carbon dioxide flux . Before applying fertilizer, variability of soil fertility was not significantly correlated with the flux of Carbon dioxide, so the difference of Carbon dioxide flux based on distance sampling can be caused by root distribution factor. After fertilizer application, variability of Carbon dioxide flux under the oil palm tree were not only affected by differences in root distribution but also greatly influenced by fertilization.

OBJECTIVE Carbapenem-resistant Enterobacteriaceae (CRE) are a significant clinical and public health concern. Understanding the distribution of CRE colonization and developing a coordinated approach are key components of control efforts. The prevalence of CRE in the District of Columbia is unknown. We sought to determine the CRE colonization prevalence within healthcare facilities (HCFs) in the District of Columbia using a collaborative, regional approach. DESIGN Point-prevalence study. SETTING This study included 16 HCFs in the District of Columbia: all 8 acute-care hospitals (ACHs), 5 of 19 skilled nursing facilities, 2 (both) long-term acute-care facilities, and 1 (the sole) inpatient rehabilitation facility. PATIENTS Inpatients on all units excluding psychiatry and obstetrics-gynecology. METHODS CRE identification was performed on perianal swab samples using real-time polymerase chain reaction, culture, and antimicrobial susceptibility testing (AST). Prevalence was calculated by facility and unit type as the number of patients with a positive result divided by the total number tested. Prevalence ratios were compared using the Poisson distribution. RESULTS Of 1,022 completed tests, 53 samples tested positive for CRE, yielding a prevalence of 5.2% (95% CI, 3.9%-6.8%). Of 726 tests from ACHs, 36 (5.0%; 95% CI, 3.5%-6.9%) were positive. Of 244 tests from long-term-care facilities, 17 (7.0%; 95% CI, 4.1%-11.2%) were positive. The relative prevalence ratios by facility type were 0.9 (95% CI, 0.5-1.5) and 1.5 (95% CI, 0.9-2.6), respectively. No CRE were identified from the inpatient rehabilitation facility. CONCLUSION A baseline CRE prevalence was established, revealing endemicity across healthcare settings in the District of Columbia. Our study establishes a framework for interfacility collaboration to reduce CRE transmission and infection. Infect Control Hosp Epidemiol 2017;38:921-929.

Roll-out and implementation of antiretroviral therapy (ART) necessitated many countries in Sub-Saharan Africa to strengthen their national health laboratory systems (NHLSs) to provide high quality HIV diagnostic and supportive services. This study was conducted to assess the performance of health laboratories in provision of HIV diagnostic and supportive services in eight districts (from four regions of Iringa, Mtwara, Tabora and Tanga), after nine years of implementation of HIV/AIDS care and treatment plan in Tanzania. In this cross-sectional study, checklists and observations were utilized to collect information from health facilities (HFs) with care and treatment centres (CTCs) for HIV/AIDS patients; on availability of laboratories, CTCs, laboratory personnel, equipment and reagents. A checklist was also used to collect information on implementation of quality assurance (QA) systems at all levels of the NHLS in the study areas. The four regions had 354 HFs (13 hospitals, 41 Health Centres (HCs) and 300 dispensaries); whereby all hospitals had laboratories and 11 had CTCs while 97.5 and 61.0% of HCs had both laboratories and CTCs, respectively. Of the dispensaries, 36.0 and 15.0% had laboratories and CTCs (mainly in urban areas). Thirty nine HFs (12 hospitals, 21 HCs and six dispensaries) were assessed and 56.4% were located in urban areas. The assessed HFs had 199 laboratory staff of different cadres (laboratory assistants = 35.7%; technicians =32.7%; attendants = 22.6%; and others = 9.1%); with >61% of the staff and 72.3% of the technicians working in urban areas. All laboratories were using rapid diagnostic tests for HIV testing. Over 74% of the laboratories were performing internal quality control and 51.4% were participating in external QA programmes. Regional and district laboratories had all key equipment and harmonization was maintained for Fluorescence-Activated Cell Sorting (FACS) machines. Most of the biochemical (58.0%) and haematological

The performance of community health service centers (CHSCs) has not been well monitored and analysed since China's latest community health reforms in 2009. The aim of the current investigation was to evaluate the performing trends of the CHSCs and to analyze the main factors that could affect the performance in Pudong new district of Shanghai, China. A regional performance assessment indicator system was applied to the evaluation of Pudong CHSCs' performance from 2011 to 2013. All of the data were sorted out by a panel, and analyzed using descriptive statistics and a generalized estimating equation model. We found that the overall performance increased annually, with a growing number of CHSCs achieving high scores. Significant differences were observed in institutional management, public health services, basic medical services and comprehensive satisfaction during the period of three years. However, we found no differences in the service scores of Chinese traditional medicine (CTM). The investigation also demonstrated that the key factors affecting performance were the location, information system level, family GP program and medical association program rather than the size of the center. However, the medical association participation appeared to have a significant negative effect on performance. It can be concluded from the three-year investigation that the overall performance was improved, but that it could have been further enhanced, especially in institutional management and basic medical service; therefore, it is imperative that CHSCs undertake approaches such as optimizing the resource allocation and utilization, reinforcing the establishment of the information system level, extending the family GP program to more local communities, and promoting the medical association initiative.

The Relationship Between State and District Content Standards:Issues of Alignment, Influence and Utility

Directory of Open Access Journals (Sweden)

Elizabeth Dutro

2004-08-01

Full Text Available At the core of standards-based reform are content standards--statements about what students should know and be able to do. Although it is state standards that are the focus of much public attention and consume substantial resources, many local school districts have developed their own content standards in the major subject areas. However, we know very little about the role state standards have played in local standards efforts. In this article we report on a study of the relationship between state and local content standards in reading in four states and districts. Through interviews with key personnel in each state, and district and analyses of state and local content standards in reading, we explored the alignment between state and district content standards, the path of influence between the two, and the role of high-stakes tests in state and districts reform efforts. Our findings suggest that alignment had multiple meanings and that state standards had differential utility to districts, ranging from helpful to benign to nuisance. This wide variability was influenced by the nature of the standards themselves, the state vision of alignment and local control, districts’ own engagement and commitment to professional development, and student performance on high-stakes tests. We explore implications for the future of content standards as the cornerstone of standards-based reform and argue that states must promote district ownership and expand accountability if state content standards are to have any relevance for local efforts to reform teaching and learning.

Overestimation of test performance by ROC analysis: Effect of small sample size

New imaging systems are often observer-rated by ROC techniques. For practical reasons the number of different images, or sample size (SS), is kept small. Any systematic bias due to small SS would bias system evaluation. The authors set about to determine whether the area under the ROC curve (AUC) would be systematically biased by small SS. Monte Carlo techniques were used to simulate observer performance in distinguishing signal (SN) from noise (N) on a 6-point scale; P(SN) = P(N) = .5. Four sample sizes (15, 25, 50 and 100 each of SN and N), three ROC slopes (0.8, 1.0 and 1.25), and three intercepts (0.8, 1.0 and 1.25) were considered. In each of the 36 combinations of SS, slope and intercept, 2000 runs were simulated. Results showed a systematic bias: the observed AUC exceeded the expected AUC in every one of the 36 combinations for all sample sizes, with the smallest sample sizes having the largest bias. This suggests that evaluations of imaging systems using ROC curves based on small sample size systematically overestimate system performance. The effect is consistent but subtle (maximum 10% of AUC standard deviation), and is probably masked by the s.d. in most practical settings. Although there is a statistically significant effect (F = 33.34, P<0.0001) due to sample size, none was found for either the ROC curve slope or intercept. Overestimation of test performance by small SS seems to be an inherent characteristic of the ROC technique that has not previously been described

Swedish district heating - owners, prices and profitability

International Nuclear Information System (INIS)

Andersson, Sofie; Werner, S.

2001-01-01

Owners, prices and profitability are examined in this report for 152 Swedish district heating companies during 1999. Only public information available has been used: Prices from a national annual consumer study, energy supplied, lengths of district heating pipes installed, and average prices for energy supplied. These companies are responsible for 96 % of all district heat supplied in Sweden. District heating systems owned by municipalities were responsible for 65 % of all district heat supply, while the share of power companies was 34 %. Other private owners accounted for 1 %. Only 12 % of the board members are women and more than 40 % of the companies have no woman in the board. The prices gathered by the annual consumer study are good estimates of the price level of district heating in Sweden. The average revenues are only 4,1 % lower than the effective average of prices gathered. Price of district heating decrease with size and market share. Use of combined heat and power plants decrease prices slightly. Lower prices with size can mainly be explained by lower energy supply costs. Calculated rates of return in relation to calculated replacement values increase slightly by size and are almost independent of age and market share. The purport of these conclusions is that the district heating companies share the cost reduction from size with their customers, while the whole benefit from high market shares is repaid to the customers. Calculated rates of return vary among the owner groups examined. Lower rates are accepted by municipalities, while power companies have higher rates at the average costs used. Total replacement costs for the 152 companies has been estimated to 89 billion Swedish crowns or 10 billion Euro. Only correlation analyses using one dimension have been used in this study. A higher degree of quality can be obtained by using multi-dimensional analyses

Full Text Available Background. This ecological study examines the relationship between food desert prevalence and academic achievement at the school district level. Design and methods. Sample included 232 suburban and urban school districts in New York State. Multiple open-source databases were merged to obtain: 4th grade science, English and math scores, school district demographic composition (NYS Report Card, regional socioeconomic indicators (American Community Survey, school district quality (US Common Core of Data, and food desert data (USDA Food Desert Atlas. Multiple regression models assessed the percentage of variation in achievement scores explained by food desert variables, after controlling for additional predictors.Results. The proportion of individuals living in food deserts significantly explained 4th grade achievement scores, after accounting for additional predictors. School districts with higher proportions of individuals living in food desert regions demonstrated lower 4th grade achievement across science, English and math. Conclusions. Food deserts appear to be related to academic achievement at the school district level among urban and suburban regions. Further research is needed to better understand how food access is associated with academic achievement at the individual level.

Edwards, Jane U; Mauch, Lois; Winkelman, Mark R

2011-02-01

To support curriculum and policy, a midwest city school district assessed the association of selected categories of nutrition and physical activity (NUTR/PA) behaviors, fitness measures, and body mass index (BMI) with academic performance (AP) for 800 sixth graders. Students completed an adapted Youth Risk Behavior Surveillance Survey (NUTR/PA behaviors), fitness assessments (mile run, curl-ups, push-ups, height, and weight) with results matched to standardized scores (Measures of Academic Progress [MAP]), meal price status, and gender. Differences in mean MAP scores (math and reading) were compared by selected categories of each variable utilizing 1-way analysis of variance. Associations were determined by stepwise multiple regression utilizing mean MAP scores (for math and for reading) as the dependent variable and NUTR/PA behaviors, fitness, and BMI categories as independent variables. Significance was set at α = 0.05. Higher MAP math scores were associated with NUTR (more milk and breakfast; less 100% fruit juice and sweetened beverages [SB]) and PA (increased vigorous PA and sports teams; reduced television), and fitness (higher mile run performance). Higher MAP reading scores were associated with NUTR (fewer SB) and PA (increased vigorous PA, reduced television). Regression analysis indicated about 11.1% of the variation in the mean MAP math scores and 6.7% of the mean MAP reading scores could be accounted for by selected NUTR/PA behaviors, fitness, meal price status, and gender. Many positive NUTR/PA behaviors and fitness measures were associated with higher MAP scores supporting the school district focus on healthy lifestyles. Additional factors, including meal price status and gender, contribute to AP. © 2011, Fargo Public School.

With the implementation of heat reforms in China, the application of thermostatic radiator valves (TRVs) has been gaining popularity in the new-style district heating systems (DHSs). The objective of this study was to investigate consumer behavior (including regulation of TRVs and opening of windows) and its influences on the hydraulic performance and energy consumption of individuals and the whole system. The concurrence rate of individual behaviors and hydraulic interactions between individuals were analyzed. This study should be helpful to gain a comprehensive understanding of the new DHSs in China and consider a proper design/control strategy for these systems. Questionnaires and field observations of consumer behavior, tests of hydraulic performance, and surveys of energy consumption were carried out in a DHS in Tianjin, which was one of the heat metering and billing demonstration projects in China. The main results of the tests were as follows: water flow performance in apartment-level heating systems were diverse because consumers' behavior was varied and unpredictable, and the hydraulic interaction between consumers living along the line of a vertical pipe was obvious, and was stronger for terminal consumers with their TRVs set to higher values; however, flow variations in the whole DHS, which included 910 households, were relatively constant. A probability analysis was carried out to explain this phenomenon, and the conclusion was drawn that when there were more than 200 consumers, the stochastic consumer regulation behavior would bring less than 10% of total flow variations. Finally, the power consumption of the circulation pump, heat consumption and energy-saving potential of this type of DHS were discussed and some suggestions for TRV regulation and pump operation were made.

Full Text Available Introduction: Karimnagar District has consistently achieved highest rates of no-scalpel vasectomy (NSV in the past decade when compared to state and national rates. This study was conducted to elucidate the underlying causes for higher acceptance of NSV in the district. Materials and Methods: A community-based, case control study was conducted. Sampling techniques used were purposive and simple random sampling. A semi-structured questionnaire was used to evaluate the socio-demographic, family characteristics, contraceptive history and predictors of contraceptive choice in 116 NSV acceptors and 120 other contraceptive users (OCUs. Postoperative complications and experiences were ascertained in NSV acceptors. Results: Age (χ2 =11.79, P value = 0.008, literacy (χ2 =17.95, P value = 0.03, duration of marriage (χ2 =14.23, P value = 0.008 and number of children (χ2 =10.45, P value = 0.01 were significant for acceptance of NSV. Among the predictors, method suggested by peer/ health worker (OR = 1.5, P value = 0.01, method does not require regular intervention (OR = 1.3, P value = 0.004 and permanence of the method (OR = 1.2, P value = 0.031 were significant. Acceptors were most satisfied with the shorter duration required to return to work and the most common complication was persistent postoperative pain among 12 (10.34% of the acceptors. Conclusion: Advocating and implementing family planning is of high significance in view of the population growth in India and drawing from the demographic profile, predictors, pool of trainers and experiences in Karimnagar District, a similar achievement of higher rates of this simple procedure with few complications can be replicated.

Is Swedish district heating operating on an integrated market? – Differences in pricing, price convergence, and marketing strategy between public and private district heating companies

International Nuclear Information System (INIS)

Åberg, M.; Fälting, L.; Forssell, A.

2016-01-01

The deregulation of the Swedish electricity market in 1996 made it possible to operate municipal district heating commercially. Until that time district heating had been organized mainly as municipal utilities. After 1996 district heating is instead expected to function on a market. In competitive and integrated markets, prices are expected to be equal, or converging. To find out if district heating operates on an integrated market the differences in price levels, price convergence, price strategy, and business goals, among municipal, private and state owned district heating companies are investigated. Price statistics was used along with results from a questionnaire that was answered by representatives for 109 Swedish district heating companies. The results show that prices among district heating systems do not converge significantly and that variations in prices among municipal systems are larger than among private and state owned systems. Furthermore, despite the fact that district heating is supposed to be commercial, a vast majority of district heating companies apply cost-based pricing and not market pricing. The municipal companies give priority to political goals before financial goals. The conclusion is that a Swedish integrated market for heat has not yet evolved, and some district heating price-controlling mechanism is necessary. - Highlights: • Price statistics and owner type data were used along with results from a questionnaire. • Results show that prices among district heating systems do not converge. • Municipal district heating companies still apply cost-based pricing to a large extent. • District heating companies are not operating on an integrated market for heat. • Some price-controlling mechanism for district heating is necessary.

In 2005, only about 8% of the Swedish detached houses had district heating system. The expansion of such systems largely depends on homeowners' adoption decisions. And, to motivate homeowners to adopt district heating, it is essential to understand their decision-making process. In this context, in June 2005 we carried out a questionnaire survey of about 700 homeowners who lived in the city of Oestersund in houses with resistance heaters (baseline survey). About 84% of the respondents did not intend to install a new heating system. Since then these homeowners were influenced by (a) an investment subsidy by the Swedish government to replace resistance heaters with district heating, a brine/water-based heat pump, or a biomass-based heating system and (b) a marketing campaign by the municipality-owned district heating company. This paper analyses how these two measures influenced about 78% of the homeowners to adopt the district heating system. For this purpose we carried out a follow-up survey of the same homeowners in December 2006 (resurvey). Results showed that the investment subsidy and the marketing campaign created a need among the homeowners to adopt a new heating system. The marketing campaign was successful in motivating them to adopt the district heating system. The marketing strategy by the district heating company corresponds to the results obtained in the baseline survey. (author)

A vast amount of the annual/national budget has been spent on the National Health Insurance program in Taiwan. However, the market for district hospitals has become increasingly competitive, and district hospitals are under pressure to optimize the use of health service resources. Therefore, we employed a clustering method to explore variations in input and output service volumes, and investigate resource allocation and health care service efficiency in district hospitals. Descriptive and cluster analyses were conducted to examine the district hospitals included in the Ministry of Health and Welfare database during 2007-2011. The results, according to the types of hospital ownership, suggested that the number of public hospitals has decreased and that of private hospitals increased; the largest increase in the number of district hospitals occurred when Taichung City was merged into Taichung County. The descriptive statistics from 2007 to 2011 indicated that 43% and 36.4% of the hospitals had 501-800 occupied beds and 101-200 physicians, respectively, and > 401 medical staff members. However, the number of outpatients and discharged patients exceeded 6001 and 90,001, respectively. In addition, the highest percentage of hospitals (43.9%) had 30,001-60,000 emergency department patients. In 2010, the number of patients varied widely, and the analysis of variance cluster results were nonsignificant (p > 0.05). District hospitals belonging to low-throughput and low-performance groups were encouraged to improve resource utilization for enhancing health care service efficiency. Copyright © 2015.

Breaking Free of Sample Size Dogma to Perform Innovative Translational Research

Science.gov (United States)

Bacchetti, Peter; Deeks, Steven G.; McCune, Joseph M.

2011-01-01

Innovative clinical and translational research is often delayed or prevented by reviewers’ expectations that any study performed in humans must be shown in advance to have high statistical power. This supposed requirement is not justifiable and is contradicted by the reality that increasing sample size produces diminishing marginal returns. Studies of new ideas often must start small (sometimes even with an N of 1) because of cost and feasibility concerns, and recent statistical work shows that small sample sizes for such research can produce more projected scientific value per dollar spent than larger sample sizes. Renouncing false dogma about sample size would remove a serious barrier to innovation and translation. PMID:21677197

Pressure Separators for District Cooling; Tryckvaexlare foer fjaerrkyla - Teknik och funktion

Energy Technology Data Exchange (ETDEWEB)

Gustafson, Bror-Arne [Fludex AB, Goeteborg (SE)] [and others

2003-07-01

About 10 pressure separators run today in commercial operation in district heating networks. Undoubtedly, the pressure separator has become a new tool for more efficient operation of district heating systems. The pressure separator makes it possible to keep different parts of the pipe network at different pressure levels without the unavoidable temperature losses of heat exchangers. The objectives of this project are to find the answers of two questions. The first question is: Will the pressure separator function in district cooling systems if it is designed in the same way as for district heating? The only difference should then be the temperatures of operation. The second question is: Is there a modified design that will perform better in district cooling systems? To find the answers of the two questions, a test rig was built in Rosenlund Power Station in Goeteborg. Also computer simulations were carried out to clarify actual phenomena. The answer to the first question is: Yes/no. Measurements show that the original design of the pressure separator can be made working at temperatures of operation typical for district cooling. It will, however, be very sensitive and is not recommended for practical applications. The answer to the second question is: Yes, there is. This makes the details of the original design less interesting. The modified design is characterized by 'Differential pressure control' instead of temperature layer control'. This means a working principle that is completely independent of operational temperatures. The TVX-tank is replaced by a 'short cut' with a spring loaded checkvalve. One of the control valves creates a differential pressure that is too low to open the check valve but high enough to keep the next checkvalve in the next short cut closed. Measurements and computer simulations show that the pressure separator in the modified design works very well in district cooling applications. The temperature losses of heat

Measurement of environmental radioactivity in Toki district

International Nuclear Information System (INIS)

1981-11-01

When the Institute of Plasma Physics, Nagoya University, expressed the hope to move into Toki district, the environmental problems accompanying the movement were discussed. The effect of the radioactivity leaking from the nuclear facility on human bodies must be far smaller than that of natural radiation, and for the purpose, the amount and fluctuation range of the natural radiation in the district must be known. The initial objectives of this cooperative research were to study on environmental radiation and to make a Geiger counter for the measurement. In 1981, a scintillation counter will be completed, and using a multi-channel pulse height analyzer, the nuclides which are the source of environmental radiation emission will be identified, and the tritium in natural water will be detected. Thus, the evaluation of environmental radiation can be carried out, and the situation before the movement of the research facility can be grasped. In this paper, the natural radioactivity in earth, atmosphere and water and cosmic ray, artificial radioactivity, and environmental radiation exposure dose are reported. Also, the manufacture of a GM counter measuring instrument and the measurements of cosmic ray background, typical earth samples and environmental radioactivity with the GM counter are reported. The related data are attached. (Kako, I.)

Full Text Available A part of our traditional culture, local clothing is style of clothing that reflects, from past to present, the cultures of the societies, out of today’s fashion. Such local pieces of clothing as bindallı, peştemal, holta, salta and üç etek are in constant change and are forgotten in time because of the industrial development and modern life style. Called üç etek as it is composed of three pieces of skirt, this local clothing has been a special piece, both in ancient times and today, that is the most common, the most accepted in Turkish women clothing. It is necessary to detect, introduce, and carry to the future the pieces of clothing that are on the verge of disappearing. Being a piece of local clothing in Serinhisar District, Denizli, üç etek is worn in wedding ceremonies and kept in boxes. In Serinhisar District, women wear şalvar, out of the fabric of üç etek knotted in wrist and waist, underneath üç etek, and they wear, inside üç etek, loose, drapable göynek made of satin or tulle (crimped fabric. Woven belt is wrapped around the waist of üç etek, tel kırma veil covers the head, and wool sock is worn on the feet and in this way traditional local clothing style is formed. During the interviews conducted with local women, üç eteks used in the past and used today were found. In terms of sewing properties, technical drawings of üç eteks were performed, and the properties of colour, pattern, fabric, shape, model and ornament are examined and they were recorded by photographs. Out of the 21 üç etek samples found, it was concluded that 6 of them can be archived and the details were mentioned in the article.

Groundwater quality is important as it is the main factor determining its suitability for drinking, domestic, agricultural and industrial purposes. The suitability of groundwater for drinking and irrigation has been assessed in north and eastern part of Krishnagiri district, South-western part of Vellore district and contiguous with Andhra Pradesh states, India. A total of 31 groundwater samples were collected in the study area. The groundwater quality assessment has been carried out by evaluating the physicochemical parameters such as pH, EC, TDS, {HCO}3^{ - }, Cl-, {SO}4^{2 - }, Ca2+, Mg2+, Na+ and K+. The dominant cations are in the order of Na+ > K+ > Ca2+ > Mg2+ while the dominant anions have the trends of Cl- > {HCO}3^{ - } > {SO}4^{2 - } > CO3. The quality of the water is evaluated using Wilcox diagram and the results reveals that most of the samples are found to be suitable for irrigation. Based on these parameters, groundwater has been assessed in favor of its suitability for drinking and irrigation purpose.

Uranium gets into drinking water when the minerals containing uranium are dissolved in groundwater. Uranium and radon concentrations have been measured in drinking water samples from different water sources such as hand pumps, tube wells and bore wells at different depths from various locations of four districts (Jind, Rohtak, Panipat and Sonipat) of Haryana, India, using the LED flourimetry technique and RAD7, electronic silicon solid state detector. The uranium (238U) and radon (222Rn) concentrations in water samples have been found to vary from 1.07 to 40.25 µg L-1 with an average of 17.91 µg L-1 and 16.06 ± 0.97 to 57.35 ± 1.28 Bq L-1 with an average of 32.98 ± 2.45 Bq L-1, respectively. The observed value of radon concentration in 43 samples exceeded the recommended limits of 11 Bq L-1 (USEPA) and all the values are within the European Commission recommended limit of 100 Bq L-1. The average value of uranium concentration is observed to be within the safe limit recommended by World Health Organization (WHO) and Atomic Energy Regulatory Board. The annual effective dose has also been measured in all the water samples and is found to be below the prescribed dose limit of 100 µSv y-1 recommended by WHO. Risk assessment of uranium in water is also calculated using life time cancer risk, life time average daily dose and hazard quotient. The high uranium concentration observed in certain areas is due to interaction of ground water with the soil formation of this region and the local subsurface geology of the region.

Soil salinity analysis on a regional scale is of great significance for protecting agriculture production and maintaining eco-environmental health in arid and semi-arid irrigated areas. In this study, the Hetao Irrigation District (Hetao) in Inner Mongolia Autonomous Region, with suffering long-term soil salinization problems, was selected as the case study area. Field sampling experiments and investigations related to soil salt contents, crop growth and yields were carried out across the whole area, during April to August in 2015. Soil salinity characteristics in space and time were systematically analyzed for Hetao as well as the corresponding impacts on crops. Remotely sensed map of soil salinity distribution for surface soil was also derived based on the Landsat OLI data with a 30 m resolution. The results elaborated the temporal and spatial dynamics of soil salinity and the relationships with irrigation, groundwater depth and crop water consumption in Hetao. In addition, the strong spatial variability of salinization was clearly presented by the remotely sensed map of soil salinity. Further, the relationship between soil salinity and crop growth was analyzed, and then the impact degrees of soil salinization on cropping pattern, leaf area index, plant height and crop yield were preliminarily revealed. Overall, this study can provide very useful information for salinization control and guide the future agricultural production and soil-water management for the arid irrigation districts analogous to Hetao.

Enhanced Performance of Community Health Service Centers during Medical Reforms in Pudong New District of Shanghai, China: A Longitudinal Survey.

Xiaoming Sun

Full Text Available The performance of community health service centers (CHSCs has not been well monitored and analysed since China's latest community health reforms in 2009. The aim of the current investigation was to evaluate the performing trends of the CHSCs and to analyze the main factors that could affect the performance in Pudong new district of Shanghai, China.A regional performance assessment indicator system was applied to the evaluation of Pudong CHSCs' performance from 2011 to 2013. All of the data were sorted out by a panel, and analyzed using descriptive statistics and a generalized estimating equation model.We found that the overall performance increased annually, with a growing number of CHSCs achieving high scores. Significant differences were observed in institutional management, public health services, basic medical services and comprehensive satisfaction during the period of three years. However, we found no differences in the service scores of Chinese traditional medicine (CTM. The investigation also demonstrated that the key factors affecting performance were the location, information system level, family GP program and medical association program rather than the size of the center. However, the medical association participation appeared to have a significant negative effect on performance.It can be concluded from the three-year investigation that the overall performance was improved, but that it could have been further enhanced, especially in institutional management and basic medical service; therefore, it is imperative that CHSCs undertake approaches such as optimizing the resource allocation and utilization, reinforcing the establishment of the information system level, extending the family GP program to more local communities, and promoting the medical association initiative.

HMIS and decision-making in Zambia: re-thinking information solutions for district health management in decentralized health systems.

Science.gov (United States)

Mutemwa, Richard I

2006-01-01

At the onset of health system decentralization as a primary health care strategy, which constituted a key feature of health sector reforms across the developing world, efficient and effective health management information systems (HMIS) were widely acknowledged and adopted as a critical element of district health management strengthening programmes. The focal concern was about the performance and long-term sustainability of decentralized district health systems. The underlying logic was that effective and efficient HMIS would provide district health managers with the information required to make effective strategic decisions that are the vehicle for district performance and sustainability in these decentralized health systems. However, this argument is rooted in normative management and decision theory without significant unequivocal empirical corroboration. Indeed, extensive empirical evidence continues to indicate that managers' decision-making behaviour and the existence of other forms of information outside the HMIS, within the organizational environment, suggest a far more tenuous relationship between the presence of organizational management information systems (such as HMIS) and effective strategic decision-making. This qualitative comparative case-study conducted in two districts of Zambia focused on investigating the presence and behaviour of five formally identified, different information forms, including that from HMIS, in the strategic decision-making process. The aim was to determine the validity of current arguments for HMIS, and establish implications for current HMIS policies. Evidence from the eight strategic decision-making processes traced in the study confirmed the existence of different forms of information in the organizational environment, including that provided by the conventional HMIS. These information forms attach themselves to various organizational management processes and key aspects of organizational routine. The study results point

Vascular Plant and Vertebrate Inventory of Saguaro National Park, Rincon Mountain District

Powell, Brian F.; Halvorson, William Lee; Schmidt, Cecilia A.

2006-01-01

Executive Summary This report summarizes the results of the first comprehensive inventory of plants and vertebrates at the Rincon Mountain District (RMD) of Saguaro National Park, Arizona. From 2001 to 2003 we surveyed for vascular plants and vertebrates (amphibians, reptiles, birds, and mammals) at the district to document the presence of species within its boundaries. Park staff also surveyed for medium and large mammals using infrared-triggered cameras from 1999 to 2005. This report summarizes the methods and results of these two efforts. Our spatial sampling design was ambitious and was one of the first of its kind in the region to colocate study sites for vegetation and vertebrates using a stratified random design. We also chose the location of some study sites non-randomly in areas that we thought would have the highest species richness. Because we used repeatable study designs and standardized field methods, these inventories can serve as the first step in a biological monitoring program for the district. We also provide an important overview of most previous survey efforts in the district. We use data from our inventory and other surveys to compile species lists and to assess inventory completeness. With the exception of plants, our survey effort was the most comprehensive ever undertaken in the district. We recorded a total of 801 plant and vertebrate species, including 50 species not previously found in the district (Table 1) of which five (all plants) are non-native species. Based on a review of our inventory and past research at the district, there have been a total of 1,479 species of plants and vertebrates found there. We believe inventories for all taxonomic groups are nearly complete. In particular, the plant, amphibian and reptile, and mammal species lists are the most complete of any comparably large natural area of the 'sky island' region of southern Arizona and adjacent Mexico. For each taxon-specific chapter we discuss patterns of species

In this study, it was aimed to determine the prevalence of E. granulosus in the Aydın district. Clean and fresh faeces samples were collected off the ground from owned dogs (n=100; 25 female, 75 male) with the range of 6-16 months old. These faeces samples were obtained in 13 villages from five different locations (Centre, Söke, Çine, Bozdoğan and Kuyucak) of the Aydın district. The prevalence of E. granulosus was investigated with PCR and prior to applications of molecular techniques, faeces samples were investigated with macroscopic and floatation methods E. granulosus was determined in only one dog (1%; 1/100) and Toxocara canis (11%), Ancylostoma caninum (%3), Taenia spp. (2%) and Capillaria spp. (1%) eggs were also identified. Current prevalence (1%) of E. granulosus in this study is lower than the other studies conducted in different parts of Turkey. Determination of E. granulosus with PCR in faeces without determining any parasites with either macroscopic or microscopic examinations could indicate the potential risk of dog faeces for animal owners, veterinarians and parasitology laboratory technicians.
