    Full Text Available Background. Malaria remains a major cause of mortality and morbidity in the world, and particularly in sub-Saharan Africa. Objectives. The aim of this study was to determine ownership and utilization of ITNs among households with children under five in the previous night. Methods. A community based cross-sectional study was conducted in Gursum district in Eastern Ethiopia. A total of 335 households were surveyed using a pretested structured questionnaire administered though house-to-house interviews. Results. Household ownership for at least one mosquito net and use of nets were 62.4% (95% CI 57.2–67.6% and 21.5% (95% CI 17.1–25.9%, respectively. Households who received or were told about ITN in the last 6 months were three times more likely to have used it than those who were not (OR 3.25; 95% CI 1.5–7.10. Households whose heads were engaged as a farmer (adjusted OR 0.137; 95% CI: 0.04–0.50 and housewife (OR 0.26; 95% CI: 0.08–0.82 were less likely to use ITN than those of other occupations. Conclusion. The findings indicate low ITN ownership and utilization among the households. Intensive health education and community mobilization effort should be employed to increase the possession and proper utilization of insecticide treated bed nets.

    Full Text Available Abstract Background To describe malaria knowledge, attitudes toward malaria and bed net use, levels of ownership and use of bed nets, and factors associated with ownership and use among pregnant women attending their first antenatal care (ANC visit in Kinshasa, DRC. Methods Women attending their first ANC visit at one maternity in Kinshasa were recruited to take part in a study where they were given free insecticide treated bed nets (ITNs and then followed up at delivery and 6 months post delivery to assess ITN use. This study describes the baseline levels of bed net ownership and use, attitudes towards net use and factors associated with net use Results Among 351 women interviewed at baseline, 115 (33% already owned a bed net and 86 (25% reported to have slept under the net the previous night. Cost was reported as the reason for not owning a net by 48% of the 236 women who did not own one. In multivariable analyses, women who had secondary school or higher education were 3.4 times more likely to own a net (95% CI 1.6–7.3 and 2.8 times more likely to have used a net (95% CI 1.3–6.0 compared to women with less education Conclusion Distribution of ITNs in antenatal clinics in this setting is needed and feasible. The potential for ITN use by this target population is high.

    Full Text Available Vector control, including the use of bed nets, is recommended as a possible strategy for eliminating lymphatic filariasis (LF in post-conflict countries such as the Democratic Republic of Congo (DRC. This study examined the geographical factors that influence bed net ownership in DRC in order to identify hard-to-reach communities that need to be better targeted. In particular, urban/rural differences and the influence of population density, proximity to cities and health facilities, plus access to major transport networks were investigated. Demographic and Health Survey geo-referenced cluster level data were used to map bed net coverage (proportion of households with at least one of any type of bed net or at least one insecticide-treated net (ITN, and ITN density (ITNs per person for 260 clusters. Bivariate and multiple logistic or Poisson regression analyses were used to determine significant relationships. Overall, bed net (30% and ITN (9% coverage were very low with significant differences found between urban and rural clusters. In rural clusters, ITN coverage/density was positively correlated with population density (r = 0.25, 0.27 respectively, p<0.01, and negatively with the distance to the two largest cities, Kinshasa or Lubumbashi (r = -0.28, -0.30 respectively, p<0.0001. Further, ownership was significantly negatively correlated with distance to primary national roads and railways (all three measures, distance to main rivers (any bed net only and distance to the nearest health facility (ITNs only. Logistic and Poisson regression models fitted to the rural cluster data indicated that, after controlling for measured covariates, ownership levels in the Bas-Congo province close to Kinshasa were much larger than that of other provinces. This was most noticeable when considering ITN coverage (odds ratio: 5.3, 95% CI: 3.67-7.70. This analysis provides key insights into the barriers of bed net ownership, which will help inform both LF

    Full Text Available Abstract Background Studies show that the burden of malaria remains huge particularly in low-income settings. Although effective malaria control measures such as insecticide-treated nets (ITNs have been promoted, relatively little is known about their equity dimension. Understanding variations in their use in low-income settings is important for scaling up malaria control programmes particularly ITNs. The objective of this paper is to measure the extent and causes of inequalities in the ownership and utilisation of bed nets across socioeconomic groups (SEGs and age groups in Tanga District, north-eastern Tanzania. Methods A questionnaire was administered to heads of 1,603 households from rural and urban areas. Households were categorized into SEGs using both an asset-based wealth index and education level of the household head. Concentration indices and regression-based measures of inequality were computed to analyse both vertical and horizontal inequalities in ownership and utilisation of bed nets. Focus Group Discussions (FGDs were used to explore community perspectives on the causes of inequalities. Results Use of ITNs remained appallingly low compared to the RBM target of 80% coverage. Inequalities in ownership of ITNs and all nets combined were significantly pro-rich and were much more pronounced in rural areas. FGDs revealed that lack of money was the key factor for not using ITNs followed by negative perceptions about the effect of insecticides on the health of users. Household SES, living within the urban areas and being under-five were positively associated with bed net ownership and/or utilisation. Conclusion The results highlight the need for mass distribution of ITN; a community-wide programme to treat all untreated nets and to promote the use of Long-Lasting Insecticidal nets (LLINs or longer-lasting treatment of nets. The rural population and under-fives should be targeted through highly subsidised schemes and mass distribution of

    Full Text Available Abstract Background Since 2002/03, an estimated 4.7 million nets have been distributed in the Southern Nations, Nationalities and Peoples Region (SNNPR among an at risk population of approximately 10 million people. Evidence from the region suggests that large-scale net ownership rapidly increased over a relatively short period of time. However, little is known about how coverage is being maintained given that the last mass distribution was in 2006/2007. This study sought to determine the status of current net ownership, utilization and rate of long lasting insecticide-treated nets (LLIN loss in the previous three years in the context of planning for future net distribution to try to achieve sustainable universal coverage. Methods A total of 750 household respondents were interviewed across malarious, rural kebeles of SNNPR. Households were randomly selected following a two-stage cluster sampling design where kebeles were defined as clusters. Kebeles were chosen using proportional population sampling (PPS, and 25 households within 30 kebeles randomly chosen. Results Approximately 67.5% (95%CI: 64.1–70.8 of households currently owned at least one net. An estimated 31.0% (95%CI 27.9–34.4 of all nets owned in the previous three years had been discarded by owners, the majority of whom considered the nets too torn, old or dirty (79.9%: 95%CI 75.8–84.0. Households reported that one-third of nets (33.7% were less than one year old when they were discarded. The majority (58.8% of currently owned nets had ‘good’ structural integrity according to a proportionate Hole Index. Nearly two-thirds of households (60.6% reported using their nets the previous night. The overriding reason for not using nets was that they were too torn (45.7%, 95% CI 39.1–50.7. Yet, few households are making repairs to their nets (3.7%, 95% CI: 2.4–5.1. Conclusions Results suggest that the life span of nets may be shorter than previously thought, with little

    Some of the challenges facing the emerging coal-bed methane (CBM) industry in Alberta include concerns regarding water protection, compression noise, well spacing and fracturing issues. One of the most fundamental questions regarding CBM is who in fact owns the resource and what rules oversee its production. The characteristics, development potential and origins of split title ownership of CBM in North America were examined in this paper. The history of freehold and Crown-owned land and the law regarding ownership and incidental production of petroleum, natural gas and bitumen in split-title situations were reviewed. The legal status of CBM in other jurisdictions was also examined. The issues of ownership and incidental production in Alberta were also discussed. The basic common law ownership principles regarding mineral ownership were applied to the characteristics of CBM in situ to conclude its possible owner in Alberta. The extension of established incidental mineral production principles to CBM were examined in the context of its characteristics. The official governmental position on CBM issues and the prospect of future legislative intervention were identified and the implications for industry and resource companies were also presented. The paper presented several recommendations including that Alberta should legislate to eliminate any right of recovery for historical or current venting of CBM during coal mining in order to remove a cloud of uncertainty over the industry. refs.

    Full Text Available Abstract Background Despite the extensive ownership and use of insecticide-treated nets (ITNs over the last decade, the effective lifespan of these nets, especially their physical integrity, under true operational conditions is not well-understood. Usefulness of nets declines primarily due to physical damage or loss of insecticidal activity. Methods A community based cross-sectional survey was used to determine the physical condition and to identify predictors of poor physical condition for bed nets owned by individuals from communities in Kwale County, coastal Kenya. A proportionate hole index (pHI was used as a standard measure, and the cut-offs for an ‘effective net’ (offer substantial protection against mosquito bites and ‘ineffective nets’ (offer little or no protection against mosquito bites were determined (pHI ≤88 (about ≤500 cm2 of holes surface area and pHI of >88 (≥500 cm2 of holes surface area, respectively. Results The vast majority (78% of the surveyed nets had some holes. The median pHI was 92 (range: 1–2,980. Overall, half of the nets were categorized as ‘effective nets’ or ‘serviceable nets’. Physical deterioration of nets was associated with higher use and washing frequency. Young children and older children were found to use ineffective bed nets significantly more often than infants, while the physical integrity of nets owned by pregnant women was similar to those owned by infants. Estuarine environment inhabitants owned nets with the worst physical condition, while nets owned by the coastal slope inhabitants were in fairly good physical condition. The results suggest that bed nets are optimally utilized when they are new and physically intact. Thereafter, bed net utilization decreases gradually with increasing physical deterioration, with most net owners withdrawing physically damaged nets from routine use. This withdrawal commonly happens following 1.5 years of use, making bed net use the most

    Full Text Available Abstract Background The elimination of malaria in Zanzibar is highly dependent on sustained effective coverage of bed-nets to avoid malaria resurgence. The Health Belief Model (HBM framework was used to explore the perceptions of malaria and bed-net use after a noticeable reduction in malaria incidence. Methods Nineteen in-depth interviews were conducted with female and male caretakers of children under five in North A district, Zanzibar. Deductive content analysis was used to identify meaning units that were condensed, coded and assigned to pre-determined elements of the HBM. Results Awareness of malaria among caretakers was high but the illness was now seen as easily curable and uncommon. In addition to the perceived advantage of providing protection against malaria, bed-nets were also thought to be useful for avoiding mosquito nuisance, especially during the rainy season when the malaria and mosquito burden is high. The discomfort of sleeping under a net during the hot season was the main barrier that interrupted consistent bed-net usage. The main cue to using a bed-net was high mosquito density, and children were prioritized when it came to bed-net usage. Caretakers had high perceived self-efficacy and did not find it difficult to use bed-nets. Indoor Residual Spraying (IRS, which was recognized as an additional means of mosquito prevention, was not identified as an alternative for bed-nets. A barrier to net ownership was the increasingly high cost of bed-nets. Conclusions Despite the reduction in malaria incidence and the resulting low malaria risk perceptions among caretakers, the benefit of bed-nets as the most proficient protection against mosquito bites upholds their use. This, in combination with the perceived high self-efficacy of caretakers, supports bed-net usage, while seasonality interrupts consistent use. High effective coverage of bed-nets could be further improved by reinforcing the benefits of bed-nets, addressing the seasonal

  11. Determinants of Bed Net Use in Southeast Nigeria following Mass Distribution of LLINs: Implications for Social Behavior Change Interventions.

    Cheryl L Russell

    Full Text Available Millions of long-lasting insecticide treated nets (LLINs have been distributed as part of the global malaria control strategy. LLIN ownership, however, does not necessarily guarantee use. Thus, even in the ideal setting in which universal coverage with LLINs has been achieved, maximal malaria protection will only be achieved if LLINs are used both correctly and consistently. This study investigated the factors associated with net use, independent of net ownership. Data were collected during a household survey conducted in Ebonyi State in southeastern Nigeria in November 2011 following a statewide mass LLIN distribution campaign and, in select locations, a community-based social behavior change (SBC intervention. Logistic regression analyses, controlling for household bed net ownership, were conducted to examine the association between individual net use and various demographic, environmental, behavioral and social factors. The odds of net use increased among individuals who were exposed to tailored SBC in the context of a home visit (OR = 17.11; 95% CI 4.45-65.79 or who received greater degrees of social support from friends and family (ptrend < 0.001. Factors associated with decreased odds of net use included: increasing education level (ptrend = 0.020, increasing malaria knowledge level (ptrend = 0.022, and reporting any disadvantage of bed nets (OR = 0.39; 95% CI 0.23-0.78. The findings suggest that LLIN use is significantly influenced by social support and exposure to a malaria-related SBC home visit. The malaria community should thus further consider the importance of community outreach, interpersonal communication and social support on adoption of net use behaviors when designing future research and interventions.

    Full Text Available Abstract Background Papua New Guinea (PNG is a highly malaria endemic country in the South-West Pacific with a population of approximately 6.6 million (2009. In 2004, the country intensified its malaria control activities with support from the Global Fund. With the aim of achieving 80% ownership and usage, a country-wide campaign distributed two million free long-lasting insecticide-treated nets (LLINs. Methods In order to evaluate outcomes of the campaign against programme targets, a country-wide household survey based on stratified multi-stage random sampling was carried out in 17 of the 20 provinces after the campaign in 2008/09. In addition, a before-after assessment was carried out in six purposively selected sentinel sites. A structured questionnaire was administered to the heads of sampled households to elicit net ownership and usage information. Results After the campaign, 64.6% of households owned a LLIN, 80.1% any type of mosquito net. Overall usage by household members amounted to 32.5% for LLINs and 44.3% for nets in general. Amongst children under five years, 39.5% used a LLIN and 51.8% any type of net, whereas 41.3% of pregnant women used a LLIN and 56.1% any net. Accessibility of villages was the key determinant of net ownership, while usage was mainly determined by ownership. Most (99.5% of the household members who did not sleep under a net did not have access to a (unused net in their household. In the sentinel sites, LLIN ownership increased from 9.4% to 88.7%, ownership of any net from 52.7% to 94.1%. Usage of LLINs increased from 5.5% to 55.1%, usage of any net from 37.3% to 66.7%. Among children under five years, usage of LLINs and of nets in general increased from 8.2% to 67.0% and from 44.6% to 76.1%, respectively (all p ≤ 0.001. Conclusions While a single round of free distribution of LLINs significantly increased net ownership, an insufficient number of nets coupled with a heterogeneous distribution led to overall

    Full Text Available Abstract Background There is no clear consensus on the most sustainable and effective distribution strategy for insecticide treated bed nets (ITNs. Tanzania has been a leader in social marketing but it is still not clear if this can result in high and equitable levels of coverage. Methods A cluster-randomized survey of ITN and bed net ownership and use was conducted in a rural area exposed to intense Plasmodium falciparum transmission in NE Tanzania where ITN distribution had been subject to routine delivery of national strategies and episodic free distribution through local clinics. Data were collected on household assets to assess equity of ITN coverage and a rapid diagnostic test for malaria (RDT was performed in all ages. Results Among 598 households in four villages the use of any or insecticidal bed nets in children less than five years of age was 71% and 54% respectively. However there was a 19.8% increase in the number of bed nets per person (p Conclusion Marked inequity persists with the poorest households still experiencing the highest risk of malaria and the lowest ITN coverage. Abolition of this inequity within the foreseeable future is likely to require mass or targeted free distribution, but risks damaging what is otherwise an effective commercial market.

    Full Text Available Abstract Background In April 2000, the Roll Back Malaria (RBM "Abuja Summit" set a target of having at least 60% of pregnant women and children under five use insecticide-treated nets (ITNs. Thereafter, programmes were implemented to create demand, reduce taxes and tariffs, spur the commercial market, and reach vulnerable populations with subsidized ITNs. Using national ITN monitoring data from the USAID-sponsored AED/NetMark project, this article examines the extent to which these activities were successful in increasing awareness, ownership, and use of nets and ITNs. Methods A series of surveys with standardized sampling and measurement methods was used to compare four countries at two points in time. Surveys were conducted in 2000 and again in 2004 (Nigeria, Senegal, Zambia or 2006 (Uganda. They contained questions permitting classification of each net as untreated, ever-treated or currently-treated (an ITN. Household members as well as nets owned were enumerated so that households, household members, and nets could be used as units of analysis. Several measures of net/ITN ownership, plus RBM ITN use indicators, were calculated. The results show the impact of ITN activities before the launch of massive free net distribution programmes. Results In 2000, treated nets were just being introduced to the public, but four to six years later the awareness of ITNs was nearly universal in all countries but Nigeria, where awareness increased from 7% to 60%. By any measure, there were large increases in ownership of nets, especially treated nets, in all countries. All countries but Nigeria made commensurate gains in the proportion of under-fives sleeping under a net/ITN, and in all countries the proportion of pregnant women sleeping under a net/ITN increased greatly. Conclusion A mix of demand creation, a strengthened commercial sector, reduced taxes and tariffs, and programmes making ITNs available at reduced prices resulted in impressive gains in

    Full Text Available Prior to a community-based efficacy trial of long-lasting insecticidal nets (LLINs in the prevention of visceral leishmaniasis (VL; also called kala-azar, a pilot study on preference of tools was held in endemic areas of India and Nepal in September 2005.LLINs made of polyester and polyethylene were distributed to 60 participants, who used the nets sequentially for 7 d. Acceptability and preference were evaluated via indirect indicators through questionnaires at three defined time points before and after use of the LLINs and through focus group discussions (FGDs. In the latter, preferences for color and size were also assessed. Untreated bed nets were owned by 87% of the households prior to the study. All users liked textures of both LLIN types after 7 d of use, but had a slight preference for those made of polyester if they were to recommend a LLIN to relatives or friends (p<0.05, mainly because of their relatively greater softness in comparison to polyethylene LLINs. Users reported that both net types reduced mosquito bites and number of insects, including sand fly (bhusana; genus Phlebotomus, inside the house. Side effects were minor and disappeared quickly.The large-scale intervention trial considered the preferences of the study population to decide on the best tool of intervention--light-blue, rectangular, polyester LLINs of different sizes.

    Objective: To ascertain the socio-cultural factors influencing the rate of utilization of insecticide treated bed nets (ITNs) in a malaria endemic city of Makurdi, north central Nigeria. Methods:The study was cross-sectional in nature using systematic sampling method to identify households. Both quantitative and qualitative data was generated from adult women using structured and semi structured questionnaires, and focused group discussions (FGDs) to obtain information on rate and patterns of utilization of ITNs. Information such as age, educational level, marital status, awareness or otherwise of the existence of malaria, and factors influencing rate of ownership and utilization of ITNs were obtained. FGDs were used to obtain qualitative information on rate of utilization of ITNs not captured in the questionnaires. Data obtained was analysed using Epi Info 6 statistical software. Results: Among the respondents interviewed, 97.0%(2 013/2 075) were aware of existence of malaria and 87.0%of these (1 751/2 013) would associate it with mosquitoes. The rate of ownership of any bed net, ITNs and untreated bed nets (UTNs) was 25.1%, 17.0%and 8.3%, respectively. Utilization of ITNs among children was 30.0%(112/373) and UTNs 12.9%(48/373). Positive contributors to ITNs utilization were literacy, enhanced economy, experience of marriage, and being gainfully employed (P<0.05);while negative contributors were ignorance, poverty and some cultural beliefs and values. Conclusions: A more synchronized advocacy should be carried out on the potential benefits of ITNs utilization and sustained. Also ITNs should be made available to the people of the community at minimal or no cost.

    Full Text Available Abstract Background A huge discrepancy was reported between ownership versus utilization of insecticide-treated bed nets (ITNs. To acquire the benefits of ITNs, households need to use and not merely own them. The objective of this study was to characterize the pattern of, and assess factors related to ITN use in one village in south Ethiopia. Methods A prospective cohort study involving 8,121 residents (in 1,388 households was carried out from April 2009 to April 2011 (101 weeks. Every week, individuals were asked whether they slept under an ITN the night before the interview. Descriptive statistics was used to report the availability and use of ITN. A negative, binomial, probability, distribution model was fitted to find out significant predictors of ITN use. Reasons for not using ITN were summarized. Results The total number of ITNs available at the beginning of the study was 1,631 (1.68 ITNs per household. On week 48, 3,099 new ITNs (PermaNet2.0 were distributed freely (2.3 ITNs per household. The number of households who received at least one new ITN was 1,309 (98.4%. The percentage of children Conclusions The ITN use fraction reached to a maximum of 69% despite near universal coverage (98.4% was achieved. Gender, age differences and distance from vector breeding site were associated with ITN use. Strategies may need to be designed addressing disproportions in ITN use, lack of convenient space to hang more than one ITN (for those receiving more than one, and measures to prolong usable life of ITNs.

    Full Text Available Abstract Background/Methods Qualitative studies suggest that bed nets affect the thermal comfort of users. To understand and reduce this discomfort the effect of bed nets on temperature, humidity, and airflow was measured in rural homes in Asia and Africa, as well as in an experimental wind tunnel. Two investigators with architectural training selected 60 houses in The Gambia, Tanzania, Philippines, and Thailand. Data-loggers were used to measure indoor temperatures in hourly intervals over a 12 months period. In a subgroup of 20 houses airflow, temperature and humidity were measured at five-minute intervals for one night from 21.00 to 6.00 hrs inside and outside of bed nets using sensors and omni-directional thermo-anemometers. An investigator set up a bed net with a mesh size of 220 holes per inch2 in each study household and slept under the bed net to simulate a realistic environment. The attenuation of airflow caused by bed nets of different mesh sizes was also measured in an experimental wind tunnel. Results The highest indoor temperatures (49.0 C were measured in The Gambia. During the hottest months of the year the mean temperature at night (9 pm was between 33.1 C (The Gambia and 26.2 C (Thailand. The bed net attenuated the airflow from a minimum of 27% (Philippines to a maximum of 71% (The Gambia. Overall the bed nets reduced airflow compared to un-attenuated airflow from 9 to 4 cm sec-1 or 52% (p -2 reduced airflow by 55% (mean; range 51 - 73%. A denser net (200 holes inch-2 attenuated airflow by 59% (mean; range 56 - 74%. Discussion Despite concerted efforts to increase the uptake of this intervention in many areas uptake remains poor. Bed nets reduce airflow, but have no influence on temperature and humidity. The discomfort associated with bed nets is likely to be most intolerable during the hottest and most humid period of the year, which frequently coincides with the peak of malaria vector densities and the force

Consequently, Ethiopia designed the 2011–2015, Malaria Prevention and Control Strategic Plan to fight the vector. It was discovered that most of the studies conducted on the use of insecticide-treated nets (ITNs were not in line with the strategic plan of the country. This study aimed to assess ITN ownership and utilization, and includes barriers related to its use among the target-area population at household (HH level. Materials and methods: A cross-sectional design was employed in Itang for this study. Data were collected by trained nurses through face-to-face interview and observation. A total of 845 participants were selected through multistage sampling, and the size was determined by using a single-population proportion formula. EPI Info and SPSS was used for analysis, and all necessary statistical association was computed in order to explain the outcome variable through explanatory variables of this study. Results: Among 845 HHs interviewed, 81.7% (690 had at least one ITN, while 52.3% (361 had used the ITN the night preceding the data-collection day. HH awareness of malaria prevention, number of ITNs, family size, number of family members sharing sleeping area/beds, sleeping patterns of adolescents, HH-head age, and inconvenience of using ITNs were found to be barriers to the use of ITNs in this study. Conclusion and recommendation: The study concluded that very few HHs owned ITNs and there was very low usage of ITNs. In recommendation, the regional health bureau and district health office should consider bigger nets that can accommodate family members who share the same sleeping area/bed in the area.

    Full Text Available Following recent large scale-up of malaria control interventions in Ethiopia, this study aimed to compare ownership and use of long-lasting insecticidal nets (LLIN, and the change in malaria prevalence using two population-based household surveys in three regions of the country. Each survey used multistage cluster random sampling with 25 households per cluster. Household net ownership tripled from 19.6% in 2006 to 68.4% in 2007, with mean LLIN per household increasing from 0.3 to 1.2. Net use overall more than doubled from 15.3% to 34.5%, but in households owning LLIN, use declined from 71.7% to 48.3%. Parasitemia declined from 4.1% to 0.4%. Large scale-up of net ownership over a short period of time was possible. However, a large increase in net ownership was not necessarily mirrored directly by increased net use. Better targeting of nets to malaria-risk areas and sustained behavioural change communication are needed to increase and maintain net use.

    Full Text Available Abstract Background Tanzania has a well-developed network of commercial ITN retailers. In 2004, the government introduced a voucher subsidy for pregnant women and, in mid 2005, helped distribute free nets to under-fives in small number of districts, including Rufiji on the southern coast, during a child health campaign. Contributions of these multiple insecticide-treated net delivery strategies existing at the same time and place to coverage in a poor rural community were assessed. Methods Cross-sectional household survey in 6,331 members of randomly selected 1,752 households of 31 rural villages of Demographic Surveillance System in Rufiji district, Southern Tanzania was conducted in 2006. A questionnaire was administered to every consenting respondent about net use, treatment status and delivery mechanism. Findings Net use was 62.7% overall, 87.2% amongst infants (0 to1 year, 81.8% amongst young children (>1 to 5 years, 54.5% amongst older children (6 to 15 years and 59.6% amongst adults (>15 years. 30.2% of all nets had been treated six months prior to interview. The biggest source of nets used by infants was purchase from the private sector with a voucher subsidy (41.8%. Half of nets used by young children (50.0% and over a third of those used by older children (37.2% were obtained free of charge through the vaccination campaign. The largest source of nets amongst the population overall was commercial purchase (45.1% use and was the primary means for protecting adults (60.2% use. All delivery mechanisms, especially sale of nets at full market price, under-served the poorest but no difference in equity was observed between voucher-subsidized and freely distributed nets. Conclusion All three delivery strategies enabled a poor rural community to achieve net coverage high enough to yield both personal and community level protection for the entire population. Each of them reached their relevant target group and free nets only temporarily

    Insecticide treated nets (ITNs) are a potential tool to help control sand flies and prevent Leishmaniasis. However, little is currently known about the response of Leishmania infected sand flies to ITNs. In this study, Phlebotomus duboscqi sand flies were infected with the parasite Leishmania major. Infected and noninfected sand flies were then evaluated against permethrin treated and untreated bed nets in a laboratory assay that required sand flies to pass through suspended netting material to feed on a mouse serving as an attractive host. The number of sand flies passing through the nets and blood feeding was recorded. There was not a significant difference in the ability of infected or noninfected sand flies to move through treated or untreated nets. Fewer sand flies entered the permethrin treated nets compared to the untreated nets, indicating that permethrin creates an effective barrier. The results show that in addition to reducing the nuisance bites of noninfected sand flies, ITNs also protect against Leishmania infected sand flies and therefore can play in key role in reducing the rates of Leishmaniasis. This study is important to the Department of Defense as it continues to develop and field new bed nets to protect service members.

    Full Text Available Abstract Background Use of insecticide-treated nets (ITNs continues to offer potential strategy for malaria prevention in endemic areas. However their effectiveness, sustainability and massive scale up remain a factor of socio-economic and cultural variables of the local community which are indispensable during design and implementation stages. Methods An ethnographic household survey was conducted in four study villages which were purposefully selected to represent socio-economic and geographical diversity. In total, 400 households were randomly selected from the four study villages. Quantitative and qualitative information of the respondents were collected by use of semi-structured questionnaires and focus group discussions. Results Malaria was reported the most frequently occurring disease in the area (93% and its aetiology was attributed to other non-biomedical causes like stagnant water (16%, and long rains (13%. Factors which significantly caused variation in bed net use were occupant relationship to household head (χ2 = 105.705; df 14; P = 0.000, Age (χ2 = 74.483; df 14; P = 0.000, village (χ2 = 150.325; df 6; P = 0.000, occupation (χ2 = 7.955; df 3; P = 0.047, gender (χ2 = 4.254; df 1; P = 0.039 and education levels of the household head or spouse (χ2 = 33.622; df 6; P = 0.000. The same variables determined access and conditions of bed nets at household level. Protection against mosquito bite (95% was the main reason cited for using bed nets in most households while protection against malaria came second (54%. Colour, shape and affordability were some of the key potential factors which determined choice, use and acceptance of bed nets in the study area. Conclusion The study highlights potential social and economic variables important for effective and sustainable implementation of bed nets-related programmes in Sub-Saharan Africa.

    Between 1991 and 1994, an intervention program with permethrin- and lambdacyhalothrin-impregnated bed nets was carried out over a period of nine months in each of five endemic, malarious areas of Ecuador, Peru, and Colombia. This program was evaluated through household surveys, blood sampling, in-depth longitudinal studies, and entomologic analysis. Eighty-four communities (including approximately 35,000 individuals) were paired according to malaria incidence, size, and coverage with bed nets and then randomly allocated to intervention and control groups. The results showed that peoples' acceptance of the measure was related to their perception of an immediate protective effect against insects. The effectiveness of the bed nets, measured as a reduction of malaria incidence in intervention communities as against control communities, showed large variations between and within the study areas. The protective efficacy varied between 0% and 70% when looking only at the postintervention differences between intervention and control groups. The average protection was 40.8% when considering a four-month incidence of clinical malaria attacks and 28.3% when considering a two-week malaria incidence. Important factors for the success of the bed net program were insect susceptibility to pyrethroids, high coverage with impregnated bed nets, high malaria incidence, good community participation, high mosquito densities when people go to bed, and a high proportion of Plasmodium falciparum. In one area, where DDT spraying in the control communities was executed, the effectiveness of bed net impregnation was slightly better than that of spraying.

    2011-06-01

    Full Text Available Abstract Insecticide-treated bed nets are the preeminent malaria control means; though there is no consensus as to a best practice for large-scale insecticide-treated bed net distribution. In order to determine the paramount distribution method, this review assessed literature on recent insecticide treated bed net distribution programmes throughout sub-Saharan Eastern Africa. Inclusion criteria were that the study had taken place in sub-Saharan Eastern Africa, targeted malaria prevention and control, and occurred between 1996 and 2007. Forty-two studies were identified and reviewed. The results indicate that distribution frameworks varied greatly; and consequently so did outcomes of insecticide-treated bed net use. Studies revealed consistent inequities between urban and rural populations; which were most effectively alleviated through a free insecticide-treated bed net delivery and distribution framework. However, cost sharing through subsidies was shown to increase programme sustainability, which may lead to more long-term coverage. Thus, distribution should employ a catch up/keep up programme strategy. The catch-up programme rapidly scales up coverage, while the keep-up programme maintains coverage levels. Future directions for malaria should include progress toward distribution of long-lasting insecticide-treated nets.

    Full Text Available BACKGROUND: Inexpensive and efficacious interventions that avert childhood deaths in sub-Saharan Africa have failed to reach effective coverage, especially among the poorest rural sectors. One particular example is insecticide-treated bed nets (ITNs. In this study, we present repeat observations of ITN coverage among rural Kenyan homesteads exposed at different times to a range of delivery models, and assess changes in coverage across socioeconomic groups. METHODS AND FINDINGS: We undertook a study of annual changes in ITN coverage among a cohort of 3,700 children aged 0-4 y in four districts of Kenya (Bondo, Greater Kisii, Kwale, and Makueni annually between 2004 and 2006. Cross-sectional surveys of ITN coverage were undertaken coincidentally with the incremental availability of commercial sector nets (2004, the introduction of heavily subsidized nets through clinics (2005, and the introduction of free mass distributed ITNs (2006. The changing prevalence of ITN coverage was examined with special reference to the degree of equity in each delivery approach. ITN coverage was only 7.1% in 2004 when the predominant source of nets was the commercial retail sector. By the end of 2005, following the expansion of heavily subsidized clinic distribution system, ITN coverage rose to 23.5%. In 2006 a large-scale mass distribution of ITNs was mounted providing nets free of charge to children, resulting in a dramatic increase in ITN coverage to 67.3%. With each subsequent survey socioeconomic inequity in net coverage sequentially decreased: 2004 (most poor [2.9%] versus least poor [15.6%]; concentration index 0.281; 2005 (most poor [17.5%] versus least poor [37.9%]; concentration index 0.131, and 2006 with near-perfect equality (most poor [66.3%] versus least poor [66.6%]; concentration index 0.000. The free mass distribution method achieved highest coverage among the poorest children, the highly subsidised clinic nets programme was marginally in favour of

    Full Text Available Abstract Background Insecticide-treated bed nets (ITNs, including long-lasting insecticidal nets (LLINs, play a primary role in global campaigns to roll back malaria in tropical Africa. Effectiveness of treated nets depends on direct impacts on individual mosquitoes including killing and excite-repellency, which vary considerably among vector species due to variations in host-seeking behaviours. While monitoring and evaluation programmes of ITNs have focuses on morbidity and all-cause mortality in humans, local entomological context receives little attention. Without knowing the dynamics of local vector species and their responses to treated nets, it is difficult to predict clinical outcomes when ITN applications are scaled up across African continent. Sound model frameworks incorporating intricate interactions between mosquitoes and treated nets are needed to develop the predictive capacity for scale-up applications of ITNs. Methods An established agent-based model was extended to incorporate the direct outcomes, e.g. killing and avoidance, of individual mosquitoes exposing to ITNs in a hypothetical village setting with 50 houses and 90 aquatic habitats. Individual mosquitoes were tracked throughout the life cycle across the landscape. Four levels of coverage, i.e. 40, 60, 80 and 100%, were applied at the household level with treated houses having only one bed net. By using Latin hypercube sampling scheme, parameters governing killing, diverting and personal protection of net users were evaluated for their relative roles in containing mosquito populations, entomological inoculation rates (EIRs and malaria incidence. Results There were substantial gaps in coverage between households and individual persons, and 100% household coverage resulted in circa 50% coverage of the population. The results show that applications of ITNs could give rise to varying impacts on population-level metrics depending on values of parameters governing interactions of

    This article provides an empirical multi-disciplinary strategy that enables to identify prevalence-elastic behaviours influencing the possession of mosquito nets and to assess the relative performance of health centers in promoting the possession of nets in Democratic Republic of Congo (DRC). We use a household survey conducted in 2009 in Haut Katanga, DRC. We combine these data with estimates on malaria prevalence from the Malaria Atlas project. Results show that households behave rationally with respect to the disease, meaning that the cause for a low possession of nets should be found elsewhere. They also show that health centers are not the most effective in promoting possession of bed nets, in areas where they are most needed for malaria control.

    Full Text Available Abstract Background Insecticide treated materials remain the mainstay for malaria prevention. The current study reports on the entomological impact of cyfluthrin impregnated bed nets on malaria transmission in Mbandjock, a semi urban locality in southern Cameroon. Several findings pertaining to the recent distribution of LLINs across Cameroon are discussed. Methods Malaria transmission and vector bionomics were monitored before and after impregnated net coverage. Bed nets were distributed in Mbandjock, whereas the locality of Nkoteng was free of bed nets during the entire study period. January to June 1997 represented the period before bed net coverage and September 1997 to September 1998 was the period after bed net coverage. Adult mosquitoes were collected by human landing catches. Mosquito genus and species were identified with morphological and molecular diagnostic tools. Anopheline salivary glands and ovaries were dissected to determine female infectious status and parity rates respectively. Results A total of 6959 anophelines corresponding to 6029 in Mbandjock and 930 in Nkoteng were collected in the course of the study. Seven species were recorded in both cities : Anopheles coustani, An. funestus, An. gambiae sl, An. moucheti, An. ziemanni, An. nili and An. paludis. An. gambiae s.l. (>95% An. gambiae S molecular form was the most abundant species representing 75.6% and 86.6% of the total anophelines caught in Mbandjock before and after bed net coverage respectively. The human biting rate (HBR in Mbandjock decreased from 17 bites/human/night before bed net coverage to less than 4 bites/human/night during the first 7 months following impregnated bed net coverage. A significant decrease of mosquito parity rate was recorded when comparing the period before (52% and after (46.5% bed net distribution. The average infection rate of malaria vectors significantly decreased from 5.3% before to 1.8% after bed net coverage (p  Conclusion The study

    Textile materials treated with synthetic repellents have the potential to provide protection against insect disease vectors but lack the residual activity necessary to achieve a prolonged effect or to be cost-effective. DEET MC is a formulation of DEET (N,N diethyl-m-toluamide) in which the repellent is gradually released from a capsule that binds the repellent. An experiment carried out on DEET-treated mosquito netting showed that the formulation repels, inhibits blood-feeding and kills mosquitoes for a period of at least 6 months under laboratory conditions. Such formulations may have the potential for use on nets against pyrethroid-resistant mosquitoes or on clothing or bedding materials distributed in disasters, emergencies or refugee camp situations.

    Background: Malaria in pregnancy is a major public health concern, contributing to roughly 11% of neonatal deaths and to 25% of all maternal deaths in some parts of the world. The World Health Organization has recommended priority interventions for malaria during pregnancy, including use of insecticide-treated nets (ITNs), but net distribution has shifted recently to a universal coverage paradigm rather than one targeting vulnerable populations. Methods: To determine whether and to what extent pregnant women are prioritized within the household for ITN use, we assessed national survey data from 2009–2013 in 10 African countries. Proportion of pregnant women who slept under an ITN the previous night and 95% confidence intervals were calculated and compared between countries. Within-country logistic regression examined whether pregnancy was significantly associated with ITN use the previous night compared with other risk groups, and the predicted probability of net use for each risk group was calculated holding other covariates constant. Results: A median 58% of households reported owning at least 1 ITN. On average, across all 10 countries, 35% of pregnant women in households with at least 1 ITN used a net. Households with universal coverage (at least 1 ITN per 2 people) had higher levels of net use among all family members; for example, 79% of pregnant women, on average, used a net in such households. In all countries, the predicted probability of ITN use by pregnant women was significantly higher than the probability of net use by most other household members except non-pregnant women of reproductive age. Conclusion: These findings suggest that both pregnant women and non-pregnant women of reproductive age are being prioritized within the household for net use. However, behavior change communication strategies are needed to achieve ITN use goals for pregnant women. PMID:25276574

A small-scale exploratory study was conducted in several locations in the Niger Delta region, Nigeria, to discover barriers against the use of bed nets, in the context of a current drive to scale up net use in Nigeria.Methods: A qualitative approach with a convenience sample was used. One to one interviews with mostly male adult volunteers were undertaken which explored typical living and sleeping arrangements, and perceptions about and barriers against the use of the mosquito prevention bed net.Results: Several key issues emerged from the qualitative data. Bed nets were not reported as widely used in this small sample. The reasons reported for lack of use included issues of convenience, especially net set up and dismantling; potential hazard and safety concerns; issues related to typical family composition and nature of accommodation; humid weather conditions; and perceptions of cost and effectiveness. Most barriers to net use concerned issues about everyday practical living and sleeping arrangements and perceptions about comfort. Interviewees identified were aware of malaria infection risks, but several also indicated certain beliefs that were barriers to net use.Conclusions: Successful control of malaria and scale up of insecticide-treated net coverage relies on community perceptions and practice. This small study has illuminated a number of important everyday life issues, which remain barriers to

Vector control measures, such as indoor residual spraying (IRS and long-lasting insecticidal bed nets (LLINs are key integral components of this programme. Compliance with these interventions is dependent on their acceptability and on the socio-cultural context of the local population. These factors need to be investigated locally prior to programme implementation. Method Twelve focus group discussions (FGDs were carried out in Malaita and Temotu Provinces, Solomon Islands in 2008. These discussions explored user perceptions of acceptability and preference for three brands of long-lasting insecticide-treated bed nets (LLINs and identified a number of barriers to their proper and consistent use. Results Mosquito nuisance and perceived threat of malaria were the main determinants of bed net use.

  2. A cluster randomized controlled cross-over bed net acceptability and preference trial in Solomon Islands: community participation in shaping policy for malaria elimination

    Science.gov (United States)

    2009-01-01

    Background A key component of the malaria elimination strategy in Solomon Islands (SI) is widespread coverage of long-lasting insecticidal nets (LLINs). The success of this strategy is dependent on LLIN acceptability and compliance. There has been unresolved debate among policy makers and donors as to which type of LLIN would be most appropriate for large-scale distribution in SI, and anecdotal reports of a lack of acceptability of certain brands of LLINs. A cluster randomized controlled crossover bed net acceptability and preference trial was therefore carried out from July to September, 2008 to inform policy and to facilitate community engagement and participation in the selection of the most appropriate LLIN for use in SI. Method A three-stage sampling method was used to randomly select the study population from Malaita Province, SI. Three brands of LLINs were assessed in this study: Olyset®, PermaNet® and DuraNet®. Bed net acceptability and preference were evaluated through surveys at three defined time points after short and longer-term trial of each LLIN. Results The acceptability of PermaNet® after short-term use (96.5%) was significantly greater than Olyset® (67.3%, p < 0.001) and DuraNet® (69.8%, p < 0.001). The acceptability of DuraNet® and Olyset® after short-term use was not significantly different at the 5% level. LLINs that were perceived not to prevent mosquito bites were significantly less acceptable than LLINs that were perceived to prevent mosquito bites (OR 0.15; 95%CI 0.03 to 0.6). LLINs that allow a pleasant night's sleep (OR 6.3; 95%CI:3.3-12.3) and have a soft texture (OR 5.7; 95%CI:1.9-20.5) were considered more acceptable than those that did not. Olyset®'s acceptability decreased over time and this was due to net wrinkling/shrinkage after washing resulting in reduced efficiency in preventing mosquito bites. The increase in DuraNet® acceptability was a result of a reduction in minor adverse events following longer-term use

    Full Text Available Abstract Background A key component of the malaria elimination strategy in Solomon Islands (SI is widespread coverage of long-lasting insecticidal nets (LLINs. The success of this strategy is dependent on LLIN acceptability and compliance. There has been unresolved debate among policy makers and donors as to which type of LLIN would be most appropriate for large-scale distribution in SI, and anecdotal reports of a lack of acceptability of certain brands of LLINs. A cluster randomized controlled crossover bed net acceptability and preference trial was therefore carried out from July to September, 2008 to inform policy and to facilitate community engagement and participation in the selection of the most appropriate LLIN for use in SI. Method A three-stage sampling method was used to randomly select the study population from Malaita Province, SI. Three brands of LLINs were assessed in this study: Olyset®, PermaNet® and DuraNet®. Bed net acceptability and preference were evaluated through surveys at three defined time points after short and longer-term trial of each LLIN. Results The acceptability of PermaNet® after short-term use (96.5% was significantly greater than Olyset® (67.3%, p and DuraNet® (69.8%, p . The acceptability of DuraNet® and Olyset® after short-term use was not significantly different at the 5% level. LLINs that were perceived not to prevent mosquito bites were significantly less acceptable than LLINs that were perceived to prevent mosquito bites (OR 0.15; 95%CI 0.03 to 0.6.

    Full Text Available Abstract Background The Timor-Leste Ministry of Health has recently finalized the National Malaria Control Strategy for 2010-2020. A key component of this roadmap is to provide universal national coverage with long-lasting insecticide-treated nets (LLINs in support of achieving the primary goal of reducing both morbidity and mortality from malaria by 30% in the first three years, followed by a further reduction of 20% by end of the programme cycle in 2020 1. The strategic plan calls for this target to be supported by a comprehensive information, education and communication (IEC programme; however, there is limited prior research into household and personal usage patterns to assist in the creation of targeted, effective, and socio-culturally specific behaviour change materials. Methods Nine separate focus group discussions (FGDs were carried out in Dili, Manatuto, and Covalima districts, Democratic Republic of Timor-Leste, in July 2010. These focus groups primarily explored themes of perceived malaria risk, causes of malaria, net usage patterns within families, barriers to correct and consistent usage, and the daily experience of users (both male and female in households with at least one net. Comprehensive qualitative analysis utilized open source analysis software. Results The primary determinants of net usage were a widespread perception that nets could or should only be used by pregnant women and young children, and the availability of sufficient sleeping space under a limited number of nets within households. Both nuisance biting and disease prevention were commonly cited as primary motivations for usage, while seasonality was not a significant factor. Long-term net durability and ease of hanging were seen as key attributes in net design preference. Very frequent washing cycles were common, potentially degrading net effectiveness. Finally, extensive re-purposing of nets (fishing, protecting crops was both reported and observed, and may

    Biodegradation of naphthalene by Ralstonia eutropha (also known as Cupriavidus necator) in a packed-bed airlift reactor with net draft tube (PBALR-nd) was studied; the Kissiris pieces were the packing material. The reactor hydrodynamics has been characterized under abiotic conditions and the dependencies of the superficial gas velocity (U G) on the gas holdup (εG), liquid mixing time, and mass transfer coefficient were determined. The improving role of the net draft tube in this small column reactor (height 42 cm, ID 5 cm) was confirmed. The flow regime was described using the εG α U G (n) expression, and bubbly flow was observed in PBALR-nd at U G kinetics of biodegradation was modeled using the Haldane and Aiba equations. The fitting of the experimental results to the models were done according to the nonlinear least square regression technique. The biokinetic constants (q m, K s, and K i) were estimated and q m as the specific biodegradation rate was equaled to 0.415 and 0.24 mgnaph./mgcell h for the Haldane and Aiba equations, respectively. The goodness of fit reported as R (2) and root-mean-square error (RMSE) showed the adequate fitness of the Haldane and Aiba models in predicting naphthalene biodegradation kinetics. On the basis of the HPLC results, a hypothetical pathway for the biodegradation was presented.

  9. Biodegradation of 2,4,6-trichlorophenol in a packed-bed biofilm reactor equipped with an internal net draft tube riser for aeration and liquid circulation

    International Nuclear Information System (INIS)

    For the aerobic biodegradation of the fungicide and defoliant 2,4,6-trichlorophenol (2,4,6-TCP), a bench-scale packed-bed bioreactor equipped with a net draft tube riser for liquid circulation and oxygenation (PB-ALR) was constructed. To obtain a high packed-bed volume relative to the whole bioreactor volume, a high AD/AR ratio was used. Reactor's downcomer was packed with a porous support of volcanic stone fragments. PB-ALR hydrodynamics and oxygen mass transfer behavior was evaluated and compared to the observed behavior of the unpacked reactor operating as an internal airlift reactor (ALR). Overall gas holdup values εG, and zonal oxygen mass transfer coefficients determined at various airflow rates in the PB-ALR, were higher than those obtained with the ALR. When comparing mixing time values obtained in both cases, a slight increment in mixing time was observed when reactor was operated as a PB-ALR. By using a mixed microbial community, the biofilm reactor was used to evaluate the aerobic biodegradation of 2,4,6-TCP. Three bacterial strains identified as Burkholderia sp., Burkholderia kururiensis and Stenotrophomonas sp. constituted the microbial consortium able to cometabolically degrade the 2,4,6-TCP, using phenol as primary substrate. This consortium removed 100% of phenol and near 99% of 2,4,6-TCP. Mineralization and dehalogenation of 2,4,6-TCP was evidenced by high COD removal efficiencies (∼95%), and by the stoichiometric release of chloride ions from the halogenated compound (∼80%). Finally, it was observed that the microbial consortium was also capable to metabolize 2,4,6-TCP without phenol as primary substrate, with high removal efficiencies (near 100% for 2,4,6-TCP, 92% for COD and 88% for chloride ions)

    Full Text Available Abstract Background BRAC, an indigenous non-governmental development organization (NGO, has been implementing a programme to prevent and control malaria in the 13 malaria-endemic districts of Bangladesh since 2007. One of the critical preventive interventions is the distribution of insecticidal bed nets (long-lasting insecticide-treated nets, LLINs and insecticide-treated ordinary nets, ITNs to the community free of cost. This study aimed to assess progress in the possession, preferential use, and knowledge on use of the LLIN/ITNs including the programme's avowed pro-poor inclination one and three and half years after intervention began. Methods A convenient sampling strategy based on malaria endemicity in the districts was adopted. First, thirty upazila (sub-district, with a population around 250,000s were selected at random, with high prevalent districts contributing more upazilas; second, from each upazila, one (2008 to two (2011 villages (covered by insecticidal bed net distribution programme were selected. From each village, households that had either one under-five child and/or a pregnant woman were included in the survey, one household being included only once. Data were collected using a pre-tested structured questionnaire. Results In all, 3,760 households in 2008 and 7,895 households in 2011 were surveyed for collecting relevant information. Proportion of households with at least one LLIN, and at least one LLIN/ITN increased (22-59 to 62-67% and 22-64% to 74-76% respectively over time, including increase in the mean number of LLIN/ITNs per household (≤ 1 to 1 +. The programme achieved > 80% coverage in sleeping under an LLIN/ITN in the case of under-five children and pregnant women, especially in the high-endemic districts. Knowledge regarding critical time of hanging the net also increased over time (7-22 to 44-54%, but remained low. The pro-poor inclination of the programme is reflected in the status of relevant indicators according

    2013-01-01

    Full Text Available Abstract Background Indoor residual insecticide spraying (IRS and long-lasting insecticide treated nets (LLINs are commonly used together even though evidence that such combinations confer greater protection against malaria than either method alone is inconsistent. Methods A deterministic model of mosquito life cycle processes was adapted to allow parameterization with results from experimental hut trials of various combinations of untreated nets or LLINs (Olyset®, PermaNet 2.0®, Icon Life® nets with IRS (pirimiphos methyl, lambda cyhalothrin, DDT, in a setting where vector populations are dominated by Anopheles arabiensis, so that community level impact upon malaria transmission at high coverage could be predicted. Results Intact untreated nets alone provide equivalent personal protection to all three LLINs. Relative to IRS plus untreated nets, community level protection is slightly higher when Olyset® or PermaNet 2.0® nets are added onto IRS with pirimiphos methyl or lambda cyhalothrin but not DDT, and when Icon Life® nets supplement any of the IRS insecticides. Adding IRS onto any net modestly enhances communal protection when pirimiphos methyl is sprayed, while spraying lambda cyhalothrin enhances protection for untreated nets but not LLINs. Addition of DDT reduces communal protection when added to LLINs. Conclusions Where transmission is mediated primarily by An. arabiensis, adding IRS to high LLIN coverage provides only modest incremental benefit (e.g. when an organophosphate like pirimiphos methyl is used, but can be redundant (e.g. when a pyrethroid like lambda cyhalothin is used or even regressive (e.g. when DDT is used for the IRS. Relative to IRS plus untreated nets, supplementing IRS with LLINs will only modestly improve community protection. Beyond the physical protection that intact nets provide, additional protection against transmission by An. arabiensis conferred by insecticides will be remarkably small, regardless of

    Malaria remains a major public health problem in Africa, and its prevalence in Cameroon stands at 29%. Long Lasting Insecticide Nets (LLINs) were distributed in 2011 to reduce malaria mortality and morbidity; however, assessment of this intervention is scanty. The present study in the Tombel health district (THD) investigated the impact of this distribution on malaria prevalence. A total of 31,657 hospital records from 3 health facilities in 3 health areas for 2010–2013 were examined. Records for 2010 and 2011 provided predistribution baseline data, while those of 2012 and 2013 represented postdistribution data. 8,679 (27.4%) patients were positive for malaria. Children below 5 years had the highest prevalence (40.7%). The number of confirmed cases was highest from June to August (peak rainy season). Malaria prevalence was higher in males (25.3%) than in females (23.2%). Malaria prevalence increased in THD from 26.7% in 2010 to 30.7% in 2011 but dropped to 22.7% in 2012 and then increased in 2013 to 29.5%. There was an overall drop in the total number of confirmed malaria cases in 2012; this decrease was significant in Ebonji (p < 0.001) and Nyasoso (p < 0.015) health areas. The distribution of LLINs led to a short lived reduction in malaria prevalence in THD. LLIN distribution and other control activities should be reinforced to keep malaria prevalence low especially among the 0–5-year group.

Records for 2010 and 2011 provided predistribution baseline data, while those of 2012 and 2013 represented postdistribution data. 8,679 (27.4% patients were positive for malaria. Children below 5 years had the highest prevalence (40.7%. The number of confirmed cases was highest from June to August (peak rainy season. Malaria prevalence was higher in males (25.3% than in females (23.2%. Malaria prevalence increased in THD from 26.7% in 2010 to 30.7% in 2011 but dropped to 22.7% in 2012 and then increased in 2013 to 29.5%. There was an overall drop in the total number of confirmed malaria cases in 2012; this decrease was significant in Ebonji (p<0.001 and Nyasoso (p<0.015 health areas. The distribution of LLINs led to a short lived reduction in malaria prevalence in THD. LLIN distribution and other control activities should be reinforced to keep malaria prevalence low especially among the 0–5-year group.

  13. Traditional nets interfere with the uptake of long-lasting insecticidal nets in the Peruvian Amazon: the relevance of net preference for achieving high coverage and use.

    Koen Peeters Grietens

    Full Text Available BACKGROUND: While coverage of long-lasting insecticide-treated nets (LLIN has steadily increased, a growing number of studies report gaps between net ownership and use. We conducted a mixed-methods social science study assessing the importance of net preference and use after Olyset® LLINs were distributed through a mass campaign in rural communities surrounding Iquitos, the capital city of the Amazonian region of Peru. METHODS: The study was conducted in the catchment area of the Paujil and Cahuide Health Centres (San Juan district between July 2007 and November 2008. During a first qualitative phase, participant observation and in-depth interviews collected information on key determinants for net preference and use. In a second quantitative phase, a survey among recently confirmed malaria patients evaluated the acceptability and use of both LLINs and traditional nets, and a case control study assessed the association between net preference/use and housing structure (open vs. closed houses. RESULTS: A total of 10 communities were selected for the anthropological fieldwork and 228 households participated in the quantitative studies. In the study area, bed nets are considered part of the housing structure and are therefore required to fulfil specific architectural and social functions, such as providing privacy and shelter, which the newly distributed Olyset® LLINs ultimately did not. The LLINs' failure to meet these criteria could mainly be attributed to their large mesh size, transparency and perceived ineffectiveness to protect against mosquitoes and other insects, resulting in 63.3% of households not using any of the distributed LLINs. Notably, LLIN usage was significantly lower in houses with no interior or exterior walls (35.2% than in those with walls (73.8% (OR = 5.2, 95CI [2.2; 12.3], p<0.001. CONCLUSION: Net preference can interfere with optimal LLIN use. In order to improve the number of effective days of LLIN protection per dollar

    Full Text Available Abstract Background To reduce the intolerable burden of malaria in pregnancy, the Ministry of Health in Uganda improved the antenatal care package by including a strong commitment to increase distribution of insecticide-treated nets (ITNs and introduction of intermittent preventive treatment with sulphadoxine-pyrimethamine for pregnant women (IPTp-SP as a national policy in 2000. This study assessed uptake of both ITNs and IPTp-SP by pregnant women as well as antenatal and maternity care use with the aim of optimizing their delivery. Methods 769 post-partum women were recruited from a rural area of central Uganda with perennial malaria transmission through a cross-sectional, community-based household survey in May 2005. Results Of the 769 women interviewed, antenatal clinic (ANC attendance was high (94.4%; 417 (57.7% visiting initially during the 2nd trimester, 242 (33.5% during the 3rd trimester and 266 (37.1% reporting ≥ 4 ANC visits. About 537 (71% and 272 (35.8% received one or ≥ 2 IPTp-SP doses respectively. Only 85 (15.8% received the first dose of IPTp-SP in the 3rd trimester. ITNs were used by 239 (31.3% of women during pregnancy and 314 (40.8% delivered their most recent pregnancy outside a health facility. Post-partum women who lacked post-primary education were more likely not to have attended four or more ANC visits (odds ratio [OR] 3.3, 95% confidence interval [CI] 1.2–9.3. Conclusion These findings illustrate the need to strengthen capacity of the district to further improve antenatal care and maternity services utilization and IPTp-SP uptake. More specific and effective community health strategies to improve effective ANC, maternity services utilization and IPTp-SP uptake in rural communities should be undertaken.

    Ecological monitoring for seagrass beds plays an important role not only in revealing the status quo, development trend, and ecological problems of seagrass resources, but also in assessing the ecological environment quality of seagrass habitats. As for seagrass monitoring and conservation, the Guangxi Beibu Gulf region and even the whole China, lag far behind Australia, USA and some regions in Europe. A niche targeting, practical and scientific ecological monitoring protocol for seagrass beds is emergently needed in this region. In this paper, according to the specific characteristics of seagrass ecosystems in Guangxi, we proposed an ecological monitoring protocol, which is based on SeagrassNet and our experiences in seagrass monitoring in past few years. It is believed that this modified SeagrassNet-based protocol is more suitable and practical when being used in this region.%海草床生态监测的作用不仅在于探讨海草资源本身的现状与发展趋势,更可通过海草监测,来评估所在海区的近海生态环境质量,或提示其它一些生态问题.在海草监测与保护方面,广西乃至中国仍远远落后于澳大利亚、美国以及欧洲一些国家和地区.对广西北部湾而言,仍缺乏具有较强针对性、可操作性和科学性的海草床生态监测方案.基于SeagrassNet监测方法,作者结合了近年来在广西开展的海草生态监测的经验,并针对广西北部湾海草生态系统的特殊性与典型性进行了部分改进,提出了适合于广西北部湾海草床的生态监测方案,是SeagrassNet在广西北部湾本土化的表现,具有较强的科学性和可操作性,以期为我国海草床的生态监测提供借鉴.

  17. Self-Ownership, World-Ownership, and Initial Acquisition

    Directory of Open Access Journals (Sweden)

    2010-11-01

    Full Text Available G.A. Cohen was perhaps libertarianism’s most formidable critic. In Self-Ownership, Freedom, and Equality he levels several strong criticisms against Robert Nozick’s theory put forth in Anarchy, State, and Utopia. In this paper, I counter several of Cohen’s criticisms. The debate operates at three stages: (1 self-ownership, (2 world-ownership, and (3 initial acquisition. At the first stage, Cohen does not attempt to refute self-ownership, but weaken its force in providing moral grounds for capitalism. Here I argue that Cohen’s attempt to overturn Nozick’s slavery argument is unsuccessful because partial-slavery, while normatively different from full-slavery, is still normatively wrong. At the second stage, Cohen argues for a joint-ownership view of the world’s resources. In particular, he claims that self-ownership is rendered merely formal in a jointly-owned world and in a capitalist world. To rebut this challenge I show that even if Cohen is right about this, libertarian self-ownership is only formal in Cohen’s peculiar case where only two people exist and one owns everything. In contrast, self-ownership in a jointly-owned world is formal in all cases. Lastly, at the third stage, Cohen argues against Nozick’s interpretation of the Lockean proviso, claiming that it is impossible to satisfy. Granting Cohen’s argument here, I go on to defend Jan Narveson’s no-proviso view of acquisition from Cohen’s thus far unanswered criticism. I show that significantly, in his critique, Cohen equivocates between positive and negative rights. Taken jointly, my responses at these three stages ground the anti-egalitarian conclusion that, in Cohen’s words, ‘[e]xtensive inequality of condition is unavoidable, or avoidable only on pain of violating people’s rights to themselves and to things.’ The sequence, then, is from self-ownership, to world-ownership, via initial acquisition.

    Full Text Available Paul J Krezanoski1–3 1Department of Medicine, 2Department of Pediatrics, Massachusetts General Hospital, 3Medicine and Pedatrics, Harvard Medical School, Boston, MA, USA Abstract: The wide-scale adoption of insecticide-treated nets (ITNs has led to significant reductions in malaria morbidity and mortality worldwide. Delivery of ITNs to the 3.2 billion people at risk of malaria requires multiple steps in diverse settings. The effectiveness of the delivery of ITNs in order to prevent malaria relies on activities that include ITN manufacturing and design, integration into national and international malaria prevention policies, supplying and distributing ITNs to households and individuals, and, finally, programs focused on spurring demand for and use of ITNs by individuals at risk. This paper reviews some recent innovative strategies for ITN delivery across these four domains, places these innovations within the context of the history of ITN deployment, and identifies opportunities to further improve the effectiveness of this ubiquitous public health tool.

    This research tests the effect of hospital ownership and size on value-based purchasing scores. Representative samples were randomly selected of short-term acute-care hospitals from across the nation and grouped into 3 categories of both ownership and size. The ownership categories are as follows: (1) for-profit, (2) nonprofit, and (3) government. The size categories are as follows: (1) small, 99 beds or fewer; (2) medium, 100 to 249 beds; (3) large, 250 beds or more. Value-based purchasing scores for the 12 process-of-care (PC) measures and the 8 patient experience-of-care (Hospital Consumer Assessment of Healthcare Providers and System [HCAHPS]) measures were calculated and combined into their single total performance score (TPS). The results reveal that for-profit controlled hospitals outperform both nonprofit and government-controlled hospitals in PC measures, HCAHPS measures, and value-based purchasing TPSs. The results also reveal that small hospitals (≤99 beds) outperform both medium hospitals (100-249 beds) and large hospitals (≥250 beds) in PC measures, HCAHPS measures, and TPS. Results are discussed. PMID:27455362

    Full Text Available This study investigates the extent and the determinants of tunnelling behaviour in five ASEAN countries (i.e. Indonesia, Malaysia, Philippines, Singapore, and Thailand. Related party transactions (RPTs in the form of loans to related parties are used as the proxy for tunnelling. With 200 firm-year observations over the period 2006-2009, this study finds a positive association between managerial ownership and the extent of tunnelling.The other important findings are that business environment (BE, foreign ownership, and independent directors are ineffective governance mechanisms to rein in tunnelling behaviour. This suggests that regulators need to evolve more effective governance mechanisms.

    Full Text Available A large number of studies have compared the performance of foreign-owned and domestic firms. However, only a limited number of studies have investigated the effect of the degree of foreign ownership on a firm's performance. We attempt to fill this gap in the literature by conducting research that distinguishes not only between domestic and foreign-owned firms, but also between wholly and partly foreign-owned firms. We also examine the possible non-linearity of the performance-ownership relationship. We divide the firms in our study into three groups by their ownership - domestic, foreign, and joint ventures. We use a regression analysis to explore whether foreign ownership influences the firms' performance, measured by several variables such as profitability, innovation performance (measured by gross expenditures on research and development activities, numbers of employees involved in research and development, production, value added, leverage and net working capital intensity. The results of our research indicate that there is a statistically significant difference in firms' performance as a result of foreign ownership in all variables except the number of research and development employees and leverage. Moreover, we show that foreign ownership and performance are linked by an inverted U-shaped relationship. A firm’s performance increases with greater foreign ownership up to the range of 61-65 %, and declines thereafter.

    Full Text Available Abstract Background Long-lasting insecticide-treated bed nets (LLITN have demonstrated a significant effect in reducing malaria-related morbidity and mortality. However, barriers on the utilization of LLITN have hampered the desired outcomes. The aim of this study was to assess the effect of community empowerment on the burden of malaria and anaemia in under-five children in Ethiopia. Methods A cluster randomized trial was done in 22 (11 intervention and 11 control villages in south-west Ethiopia. The intervention consisted of tailored training of household heads about the proper use of LLITN and community network system. The burden of malaria and anaemia in under-five children was determined through mass blood investigation at baseline, six and 12 months of the project period. Cases of malaria and anaemia were treated based on the national protocol. The burden of malaria and anaemia between the intervention and control villages was compared using the complex logistic regression model by taking into account the clustering effect. Eight Focus group discussions were conducted to complement the quantitative findings. Results A total of 2,105 household heads received the intervention and the prevalence of malaria and anaemia was assessed among 2410, 2037 and 2612 under-five children at baseline, six and 12 months of the project period respectively. During the high transmission/epidemic season, children in the intervention arm were less likely to have malaria as compared to children in the control arm (OR = 0.42; 95%CI: 0.32, 0.57. Symptomatic malaria also steadily declined in the intervention villages compared to the control villages in the follow up periods. Children in the intervention arm were less likely to be anaemic compared to those in the control arm both at the high (OR = 0.84; 95%CI: 0.71, 0.99 and low (OR = 0.73; 95%CI: 0.60, 0.89 transmission seasons.

    Full Text Available Abstract Background In Ethiopia, the utilization of long-lasting insecticide-treated bed nets (LLITN is hampered by behavioural factors such as low awareness and negative attitude of the community. The aim of this study was to present the design and baseline results of a cluster randomized trial on the effect of training of household heads on the use of LLITN. Methods This baseline survey was undertaken from February to March, 2009 as part of a randomized cluster trial. A total of 11 intervention and 11 control Gots (villages were included in the Gilgel Gibe Field Research Centre, south-west Ethiopia. House to house visit was done in 4135 households to collect information about the use of LLITN and socio-demographic variables. For the diagnosis of malaria and anaemia, blood samples were collected from 2410 under-five children and 242 pregnant women. Results One fourth of the households in the intervention and control Gots had functional LLITN. Only 30% of the observed LLITN in the intervention and 28% in the control Gots were hanged properly. Adults were more likely to utilize LLITN than under-five children in the control and intervention Gots. The prevalence of malaria in under-five children in the intervention and control Gots was 10.5% and 8.3% respectively. The intervention and control Gots had no significant difference concerning the prevalence of malaria in under-five children, [OR = 1.28, (95%CI: 0.97, 1.69]. Eight (6.1% pregnant women in the intervention and eight (7.2% in the control Gots were positive for malaria (P = 0.9. Children in the intervention Gots were less likely to have anaemia than children in the control Gots, [OR = 0.75, (95%CI: 0.62, 0.85]. Conclusion The availability and utilization of LLITN was low in the study area. The prevalence of malaria and anaemia was high. Intervention strategies of malaria should focus on high risk population and vulnerable groups.

  1. Nuclear energy center finance and ownership considerations

    International Nuclear Information System (INIS)

    Finance and ownership alternatives for a nuclear energy center (NEC) in South Carolina are analyzed in the context of the capital market and tax differences among alternatives. The ownership alternatives considered are (1) the private or private/public joint venture, (2) full public ownership and (3) a hybrid ownership form featuring federal involvement in the initial site development and permit phase, followed by a transition to private ownership. Public ownership is associated with considerably lower out-of-pocket costs than private ownership; the difference between the two, however, is related to subsidies from other parts of society to electricity customers of a publicly owned NEC. The attitudes of participating utilities on ownership forms are examined, with the finding of general strong opposition to increased federal involvement in the electric utility industry through NEC ownership. The conclusion is that the private-private/public joint venture is the preferable ownership form and that public ownership should be employed only if the private sector fails to respond to future energy demand

    Employee-owned companies are those where the broad group of employees owns the majority of shares. They have been widespread in the early transition process in Eastern Europe. This raises the question of why this type of ownership was so frequently used in some of the countries involved, and why...... there was a subsequent rapid transfer to manager ownership or outside ownership. This article gives a theoretical overview of the factors driving and hampering employee ownership, and develops hypotheses about how the transition process provided specific conditions for the development of these firms. The predictions...... employee ownership. The article concludes that privatization was the main determinant for the initial spread of employee ownership. However, other factors undermined the sustainability of employee-owned firms. No institutions created a framework for employee ownership. The long and deep production crisis...

    Previous theoretical studies on the debt shifting behavior of multinationals have assumed affiliates of multinationals to be wholly owned. We develop a model that allows a multinational firm to determine both the leverage and ownership structure in affiliates endogenously. A main finding is that affiliates with minority owners have less debt than wholly owned affiliates and therefore a less tax efficient financing structure. This is due to an externality that arises endogenously in our model,...

    Full Text Available Em 1992 foi feita uma investigação sobre o efeito protetor do uso de mosquiteiros impregnados com deltametrina, em uma população do município de Costa Marques, Rondônia, sujeita à transmissão malárica. Os mosquiteiros impregnados se comportaram de modo semelhante aos não impregnados, sem modificar os índices de infecção na época de baixa transmissão. A análise multivariada, por idade e títulos de anticorpos, mostrou uma proteção significante para o grupo com mosquiteiros impregnados contra o risco de infecção, apenas na estação de alta transmissão, quando os mosquiteiros foram usados mais regularmente. Não houve diferença no efeito de ambos os tipos de mosquiteiros na prevenção de elevadas parasitemias. Ao fim do estudo, ocorreu diminuição da prevalência de esplenomegalia em ambos os grupos, porém houve uma aparente recuperação da taxa normal de hematócrito em menores de 15 anos de idade em uso de mosquiteiros impregnados.In 1992 an investigation regarding the value of insecticide impregnated mosquito nets was conducted in the municipality of Costa Marques, Rondonia. Impregnated mosquito nets gave similar protection to those not impregnated, without modifying the incidence of infection during the season of low transmission. The multivariate analysis for age and antibody titre showed a significant protection of impregnated nets against the risk of infection only in the season of high transmission, when bed nets were used more correctly. There was no difference in the effect of both kinds of bed nets in the prevention of high parasitaemia. At the end of the study, there was a reduction of the prevalence of splenomegaly in both groups but hematocrit values rose to normal in the below 15 year olds using impregnated nets.

    2012-05-01

    Fractional Aircraft Ownership is a new concept in flight ownership management system where each individual or corporation may own a fraction of an aircraft. In this system, the owners have privilege to schedule their flight according to their needs. Fractional management companies (FMC) manages all aspects of aircraft operations, including utilization of FMC's aircraft in combination of outsourced aircrafts. This gives the owners the right to enjoy the benefits of private aviations. However, FMC may have complicated business requirements that neither commercial airlines nor charter airlines faces. Here, optimization models are constructed to minimize the number of aircrafts in order to maximize the profit and to minimize the daily operating cost. In this paper, three kinds of demand scenarios are made to represent different flight operations from different types of fractional owners. The problems are formulated as an optimization of profit and a daily operational cost to find the optimum flight assignments satisfying the weekly and daily demand respectively from the owners. Numerical results are obtained by Genetic Algorithm method.

    Full Text Available Abstract Background There has been recent large scale-up of malaria control interventions in Ethiopia where transmission is unstable. While household ownership of long-lasting insecticidal nets (LLIN has increased greatly, there are concerns about inadequate net use. This study aimed to investigate factors associated with net use at two time points, before and after mass distribution of nets. Methods Two cross sectional surveys were carried out in 2006 and 2007 in Amhara, Oromia and SNNP regions. The latter was a sub-sample of the national Malaria Indicator Survey (MIS 3R. Each survey wave used multi-stage cluster random sampling with 25 households per cluster (224 clusters with 5,730 households in Baseline 2006 and 245 clusters with 5,910 households in MIS 3R 2007. Net ownership was assessed by visual inspection while net utilization was reported as use of the net the previous night. This net level analysis was restricted to households owning at least one net of any type. Logistic regression models of association between net use and explanatory variables including net type, age, condition, cost and other household characteristics were undertaken using generalized linear latent and mixed models (GLLAMM. Results A total of 3,784 nets in 2,430 households were included in the baseline 2006 analysis while the MIS 3R 2007 analysis comprised 5,413 nets in 3,328 households. The proportion of nets used the previous night decreased from 85.1% to 56.0% between baseline 2006 and MIS 3R 2007, respectively. Factors independently associated with increased proportion of nets used were: LLIN net type (at baseline 2006; indoor residual spraying (at MIS 3R 2007; and increasing wealth index at both surveys. At both baseline 2006 and MIS 3R 2007, reduced proportion of nets used was independently associated with increasing net age, increasing damage of nets, increasing household net density, and increasing altitude (>2,000 m.

  6. WELFARE IMPLICATIONS OF TIMBERLAND OWNERSHIP CHANGES IN THE U.S. TIMBER MARKETS

    Directory of Open Access Journals (Sweden)

    Mohammad Mahfuzur Rahman

    2016-07-01

    Full Text Available In the last two decades, many forest product firms in the U.S. either divested their timberlands to timber investment management organizations (TIMOs and conservation organizations or converted their corporate structures from C corporations to real estate investment trusts (REITs. All landowners sold smaller timberland tracts for nonforestry uses. Reduced timber supplies from conservation organizations and timberland loss to other nonforestry uses have consequences on producer and consumer surpluses in the U.S. timber markets. Equilibrium displacement model has been employed to evaluate the welfare changes in U.S. timber markets attributed to timberland ownership changes. Net reduction of timber supply contributed to the reduction of social surplus by $43 million in 2006. Compared to the $33 billion plus U.S. timber markets, this welfare reduction was small. Overall, this article explains the shifts of economic surpluses among producers and net surplus reduction for the society attributed to timberland ownership changes in the United States.

    Full Text Available Orientation: Psychological ownership emerged recently as a positive psychological resource that could be measured and developed and that could affect the performance of organisations.Purpose: The purpose of this study was to develop an instrument to measure psychological ownership in a South African context.Motivation for the study: It was found that previous instruments for the measurement of psychological ownership lacked the ability to grasp the extensive reach of psychological ownership.Research design, approach and method: A quantitative cross-sectional survey was conducted on a non-probability convenience sample of 713 skilled, highly-skilled and professional employees from various organisations in both the private and public sectors in South Africa.Main findings: Although a 69-item measurement instrument was developed in order to capture the proposed seven-dimensional psychological ownership construct, it became evident when analysing the data that a four-factor model comprising 35 items was suitable.Practical/managerial implications: If a sense of psychological ownership toward an organisation could be established amongst its employees by addressing the factors as measured by the South African Psychological Ownership Questionnaire, organisations could become enhanced workplaces and, as a result, sustainable performance could be promoted and staff could be retained.Contribution/value-add: The instrument for measuring psychological ownership in a South African context could serve as a diagnostic tool that would allow human resource professionals and managers to determine employees’ sense of psychological ownership regarding their organisation and to focus specifically on weak dimensional areas that could be improved.

    2010-12-01

    Full Text Available This study documents a decline in the levels of corporate ownership concentration between 1996 and 2007. When compared to previous studies, the incidence of ownership stakes of 20% or larger has decreased form 60% to 41% of the total population of publicly listed Canadian firms. Regional disparities among provinces remain important. Ontario, Alberta, and British Columbia have the most widely-held firms, while Quebec and Atlantic Canada show the most concentrated corporate ownership patterns. The interpretation of these results requires a complex understanding of historical, demographic, cultural, political and institutional factors.

We use accounting identities to define coefficients of control, such that any (direct or indirect) control of a firm may be identified using these coefficients. This procedure is sufficient to show that under cross-ownership the voting rights associated with ownership are typically underestimated. We demonstrate b...

  11. Ownership Concentration, Top Management and Board Compensation

    Directory of Open Access Journals (Sweden)

    Marcos Barbosa Pinto

    2013-05-01

    Full Text Available The degree of ownership concentration may influence executive and board compensation (Bebchuk & Fried, 2003. This article analyzes this relationship. Detailed information about top management and board compensation became available starting in 2010 through new Securities Commission filings. Linear regression models applied to a sample of 315 Brazilian companies traded on the national exchange indicate a negative and statistically significant economic correlation between executive compensation and the degree of ownership concentration. Ceteris paribus, companies with a lower degree of ownership concentration pay higher compensation to top executives. Family controlled companies pay more to their chief executive, but not to the managerial team as a whole, and the compensation of directors increases with a greater proportion of control group members or their relatives on the board. There was support for the Managerial Power Hypothesis in companies with a lower degree of ownership concentration and for the extraction of private benefits in companies where it is greater.

    1981-10-01

    Ownership patterns in the coal industry are highly complex. Many producers are diversified into other lines of activity. The pattern and extent of this diversification has varied through time. In the past, steel and nonferrous metals companies had major coal industry involvement. This is still true today. However, other types of enterprises have entered the industry de novo or through merger. Those of greatest significance in recent times have involved petroleum and particularly public utility companies. This report attempts to identify, as accurately as possible, production ownership patterns in the coal industry. The audience for this Directory is anyone who is interested in accurately tracing the ownership of coal companies to parent companies, or who is concerned about the structure of ownership in the US coal industry. This audience includes coal industry specialists, coal industry policy analysts, economists, financial analysts, and members of the investment community.

By contrast, a phenomenal account of the sense of ownership holds...... that one can experience something as one's own without thinking about anything as one's own. I argue that we have no reason to favour phenomenal accounts over cognitive accounts, that cognitive accounts are plausible given that much of our mental activity has unnoticed effects on our mental life......, and that certain illusory experiences of body ownership sometimes described as thought-independent may be best explained as imaginative perceptual experiences....

    We assessed gun ownership rates in 2013 across the USA and the association between exposure to a social gun culture and gun ownership. We used data from a nationally representative sample of 4000 US adults, from 50 states and District of Columbia, aged >18 years to assess gun ownership and social gun culture performed in October 2013. State-level firearm policy information was obtained from the Brady Law Center and Injury Prevention and Control Center. One-third of Americans reported owning a gun, ranging from 5.2% in Delaware to 61.7% in Alaska. Gun ownership was 2.25-times greater among those reporting social gun culture (PR=2.25, 95% CI 2.02 to 2.52) than those who did not. In conclusion, we found strong association between social gun culture and gun ownership. Gun cultures may need to be considered for public health strategies that aim to change gun ownership in the USA.

We used data from a nationally representative sample of 4000 US adults, from 50 states and District of Columbia, aged >18 years to assess gun ownership and social gun culture performed in October 2013. State-level firearm policy information was obtained from the Brady Law Center and Injury Prevention and Control Center. One-third of Americans reported owning a gun, ranging from 5.2% in Delaware to 61.7% in Alaska. Gun ownership was 2.25-times greater among those reporting social gun culture (PR=2.25, 95% CI 2.02 to 2.52) than those who did not. In conclusion, we found strong association between social gun culture and gun ownership. Gun cultures may need to be considered for public health strategies that aim to change gun ownership in the USA. PMID:26124073

  8. The effect of managerial ownership on the demand for conservatism.

    OpenAIRE

    Eersteling, Gjalt

    2016-01-01

    In this paper the relation between managerial ownership and conservatism is examined. Managerial ownership decreases agency problems caused by the separation of ownership and control. Managerial ownership increases the time horizon of managers and decreases expropriating behaviour. Conservatism is hypothesized to have the same effect on managers due to the asymmetric timeliness of earnings. This suggest that in firms with lower managerial ownership a demand for conservatism arises to substitu...

  10. Ownership Structure and Earnings Management: Evidence from Portugal

    Directory of Open Access Journals (Sweden)

    Full Text Available This paper examines the relationship between corporate ownership structure in Portugal and earnings management. The Portuguese governance structure is characterised by the dominance ofthe largest shareholder who typically exercises significant influences on management decisions directly or indirectly. Existing literature suggests that ownership structure decreases the incentive to manage earnings but also provides the opportunity and incentive to manipulate earnings. Therefore, the main purpose of this paper is to analyse whether a firm’s ownership structure (measured with three variables: managerial ownership, ownership concentration and institutional ownershipexacerbate or alleviate earnings management. Using a sample of 34 non-financial listed Portuguese firms for years from 2002 to 2007, we find that discretionary accruals as a proxy for earnings management is negatively related both to managerial ownership and to ownership concentration. The study’s results suggest that both managerial ownership and ownership concentration improvethe quality of annual earnings by reducing the levels of earnings management.

  11. Negotiating ownership: Understanding the cultivation of student ownership in an urban science video project

    O'Neill, Tara Breckenridge

    The intention of this study is to define student ownership in an informal science learning setting in a low performing middle school in New York City, to investigate what characterizes such ownership, and to determine how to cultivate it. In addition, I am interested in investigating the effects of the students' sense of ownership on their sense of self, in relation to the study and the practice of science and the role of race in power in framing the context in which ownership is cultivated. This is a qualitative study; specifically I apply a critical ethnography framework for both data collection an analysis. This study is based in an informal science video project lasting three years in which two groups of sixth and seventh grade students, made three movies about their perceptions of science, who they felt knew science, and how science related to their lives. In chapter IV, I explain that students' expression of ownership is visible via five main themes. (1) Students viewed themselves in relation to science in ways that are positive, empowering, and full of self-awareness. (2) Students actively and purposefully chose to expend their capital. (3) Students expressed pride around the multiple contexts. (4) Students used the video project to effect positive changes in their lives. (5) Students expressed positive and realistic vision for the role that science played in their lives. In chapter V, I explain that student agency and student ownership share a dialectic relationship in which student agency must be valued to cultivate student ownership and the cultivation of student ownership expands student agency. Lastly, in chapter VII, I explore the role race and power play in framing the context in which ownership is cultivated. Specifically, I argue that in order to cultivate ownership in high-poverty urban science learning environments, the teacher in this environment must be critically reflective of her/his practice and pay particular attention to issues of race and

  12. Voluntary self-touch increases body ownership

    Directory of Open Access Journals (Sweden)

    Masayuki eHara

    2015-10-01

    Full Text Available Experimental manipulations of body ownership have indicated that multisensory integration is central to forming bodily self-representation. Voluntary self-touch is a unique multisensory situation involving corresponding motor, tactile and proprioceptive signals. Yet, even though self-touch is frequent in everyday life, its contribution to the formation of body ownership is not well understood. Here we investigated the role of voluntary self-touch in body ownership using a novel adaptation of the rubber hand illusion (RHI, in which a robotic system and virtual reality allowed participants self-touch of real and virtual hands. In the first experiment, active and passive self-touch were applied in the absence of visual feedback. In the second experiment, we tested the role of visual feedback in this bodily illusion. Finally, in the third experiment, we compared active and passive self-touch to the classical RHI in which the touch is administered by the experimenter. We hypothesized that active self-touch would increase ownership over the virtual hand through the addition of motor signals strengthening the bodily illusion. The results indicated that active self-touch elicited stronger illusory ownership compared to passive self-touch and sensory only stimulation, and indicate an important role of active self-touch in the formation of bodily self.

  13. Inducing illusory ownership of a virtual body

    Directory of Open Access Journals (Sweden)

    Mel Slater

    2009-09-01

    Full Text Available We discuss three experiments that investigate how virtual limbs and bodies can come to feel like real limbs and bodies. The first experiment shows that an illusion of ownership of a virtual arm appearing to project out of a person’s shoulder can be produced by tactile stimulation on a person’s hidden real hand and synchronous stimulation on the seen virtual hand. The second shows that the illusion can be produced by synchronous movement of the person’s hidden real hand and a virtual hand. The third shows that a weaker form of the illusion can be produced when a brain-computer interface is employed to move the virtual hand by means of motor imagery without any tactile stimulation. We discuss related studies that indicate that the ownership illusion may be generated for an entire body. This has important implications for the scientific understanding of body ownership and several practical applications.

  14. What Does Stock Ownership Breadth Measure?

    Science.gov (United States)

    Choi, James J; Jin, Li; Yan, Hongjun

    2013-07-01

    Using holdings data on a representative sample of all Shanghai Stock Exchange investors, we show that increases in ownership breadth (the fraction of market participants who own a stock) predict low returns: highest change quintile stocks underperform lowest quintile stocks by 23% per year. Small retail investors drive this result. Retail ownership breadth increases appear to be correlated with overpricing. Among institutional investors, however, the opposite holds: Stocks in the top decile of wealth-weighted institutional breadth change outperform the bottom decile by 8% per year, consistent with prior work that interprets breadth as a measure of short-sales constraints.

    2007-01-01

    The purpose of this paper is to investigate the relationship between investor protection, ownership structure and corporate valuation. La Porta showed that there existed a simple linear relationship between corporate valuation and the holding percentage of controlling shareholders. But recent empirical evidence does not support it. A nonlinear relationship is proved between ownership structure and corporate valuation by relaxing the assumption of La Porta's model in this paper. There exists a positive relation between investor protection and corporate valuation. Our empirical research shows that this relation is significantly positive indeed.

  17. Efficiency and Ranking of Indian Pharmaceutical Industry: Does Type of Ownership Matter?

    Directory of Open Access Journals (Sweden)

    Varun MAHAJAN

    2014-11-01

    Full Text Available This paper measures the technical efficiency, super-efficiency, slacks, and input/output targets for large Indian pharmaceutical firms according to ownership by applying Data Envelopment Analysis (DEA approach. The paper uses raw material, salaries & wages, advertisement & marketing and capital usage cost as input variables and net sales revenue as output variable. The super-efficiency model is applied to rank firms on the basis of efficiency scores. The paper finds that mean overall technical efficiency scores of Private Indian and Private Foreign are higher than Group-owned firms, suggesting that type of ownership affects the performance of a given firm. Further, foreign firms were found to have minimum slacks in inputs, evidently owing to their superior technology, better engineering skills and managerial practices. The study suggests that the inputs, such as, advertisement & marketing expenditure, and also the usage of labour and capital are required to be utilized far more productively in order to improve efficiency.

    2014-09-01

    To what extent do early intuitions about ownership depend on cultural and socio-economic circumstances? We investigated the question by testing reasoning about third party ownership conflicts in various groups of three- and five-year-old children (N=176), growing up in seven highly contrasted social, economic, and cultural circumstances (urban rich, poor, very poor, rural poor, and traditional) spanning three continents. Each child was presented with a series of scripts involving two identical dolls fighting over an object of possession. The child had to decide who of the two dolls should own the object. Each script enacted various potential reasons for attributing ownership: creation, familiarity, first contact, equity, plus a control/neutral condition with no suggested reasons. Results show that across cultures, children are significantly more consistent and decisive in attributing ownership when one of the protagonists created the object. Development between three and five years is more or less pronounced depending on culture. The propensity to split the object in equal halves whenever possible was generally higher at certain locations (i.e., China) and quasi-inexistent in others (i.e., Vanuatu and street children of Recife). Overall, creation reasons appear to be more primordial and stable across cultures than familiarity, relative wealth or first contact. This trend does not correlate with the passing of false belief theory of mind. PMID:24955501

    How does ownership concentration effect firm performance in emerging markets? On one hand, concentrated ownership leads to higher agency problems, and on the other hand, it minimizes agency problems by removing the free-rider problem. Using a large dataset of ownership concentration from the MENA...... region during the period between 2004 and 2008, we document that ownership concentration, as itself, may not have a significant impact on firm performance. It is, rather, the way concentrated firms govern themselves that determine their performance. We argue that concentrated ownership firms, being aware...... of the agency problems embedded in their ownership structure, appoint one of big-four auditors as their external auditor to signal the market that they are disclosing reliable information. Our results also show a significantly positive relationship between ownership concentration and the choice of auditor. We...

    Coloured Petri nets (CP-nets) can be used for several fundamentally different purposes like functional analysis, performance analysis, and visualisation. To be able to use the corresponding tool extensions and libraries it is sometimes necessary to include extra auxiliary information in the CP......-net. An example of such auxiliary information is a counter which is associated with a token to be able to do performance analysis. Modifying colour sets and arc inscriptions in a CP-net to support a specific use may lead to creation of several slightly different CP-nets – only to support the different...... uses of the same basic CP-net. One solution to this problem is that the auxiliary information is not integrated into colour sets and arc inscriptions of a CP-net, but is kept separately. This makes it easy to disable this auxiliary information if a CP-net is to be used for another purpose. This paper...

  1. Family-Concentrated Ownership in Chinese PLCs: Does Ownership Concentration Always Enhance Corporate Value?

    Directory of Open Access Journals (Sweden)

    2014-02-01

    Full Text Available In this paper we investigate the relationship between family ownership structure and corporate value across a sample of 1314 firm-year observations of China’s family publicly listed companies (PLCs, from 2004 to 2008. We find a significant inverse-U-shaped relationship between the controlling family’s ultimate cash-flow rights and corporate value; as measured by Tobin’s Q. That is, as family-ownership concentration increases, corporate value first increases and then decreases. This finding refreshes our understanding of the relationship between family-ownership concentration and corporate value in emerging economies such as found in China. We corroborate prior findings that when controlling families hold excess control over cash-flow rights, corporate value is significantly lowered, while multiple large shareholders structure is significantly associated with higher corporate value. In addition; board independence is found to significantly improve corporate value in the context of family-concentrated ownership. We also test for potential endogeneity between family ownership and corporate value and find our results to be robust.

    2012-01-01

    We used computational linguistic and content analyses to explore the concept of project ownership for undergraduate research. We used linguistic analysis of student interview data to develop a quantitative methodology for assessing project ownership and applied this method to measure degrees of project ownership expressed by students in relation to different types of educational research experiences. The results of the study suggest that the design of a research experience significantly influences the degree of project ownership expressed by students when they describe those experiences. The analysis identified both positive and negative aspects of project ownership and provided a working definition for how a student experiences his or her research opportunity. These elements suggest several features that could be incorporated into an undergraduate research experience to foster a student's sense of project ownership.

  10. Corporate Ownership, Control, and Firm Performance in Victorian Britain

    OpenAIRE

    Acheson, Graeme G.; Campbell, Gareth; Turner, John D; Vanteeva, Nadia

    2016-01-01

    Scholars have long debated whether ownership structure matters for firm performance. The standard view with respect to Victorian Britain is that family-controlled companies had a detrimental effect on operating profit and shareholder value. Here, we examine this view using a hand-collected corporate ownership dataset. Our main finding is that it was not necessarily the broad structure of corporate ownership that mattered for performance, but whether family blockholders had a governance role. ...

    2006-01-01

    The Berle-Means thesis (1932) implies that diffuse ownership adversely affects firm performance. This paper tries to investigate whether there is strong evidence to support the notion that variations across firms in observed ownership structures result in systematic variations in observed firm performance. We test this hypothesis by assessing the impact of the structure of ownership on corporate performance, measured by profitability, using data for 175 Greek listed firms. Following Demsetz a...

  12. Insider ownership and corporate performance: evidence from Germany

    In this paper we address the question whether insider ownership affects corporate performance. Evidence coming from studies dealing with Anglo-Saxon countries is rather inconclusive, especially because it seems that results are significantly affected by endogeneity. Economically, this is due to the fact that in these countries insider ownership seems to be mainly driven by management's compensation contracts. We argue that Germany is different in this regard, as insider ownership often is rel...

    We consider priced timed Petri nets, i.e., unbounded Petri nets where each token carries a real-valued clock. Transition arcs are labeled with time intervals, which specify constraints on the ages of tokens. Furthermore, our cost model assigns token storage costs per time unit to places, and firing costs to transitions. This general model strictly subsumes both priced timed automata and unbounded priced Petri nets. We study the cost of computations that reach a given control-state. In general...

    2006-07-01

    After it had ushered in the liberalisation of the energy economy through its initial enactment in 1998 the Energy Economy Law was fundamentally revised to stipulate the complete unbundling of integrated power supply companies in terms of their legal status, accounting and operations, in accordance with Directives 2003/54 and 2003/55. While this amended version has yet to take effect, the European Union has already set its sights on its next unbundling project. This is the project of maximum unbundling, also referred to as ownership unbundling. Its proponents expect of it that it will eliminate all incentives that encourage network operators to discriminate against interlinked production and distributive companies. Quite apart from a political assessment of such short-sighted energy policy this raises the question as to whether the introduction of ownership unbundling by the European legislature, and consequently also by the German government, is legally admissible at all. Any answer to this question must first clarify the precise meaning of ownership unbundling. For all the support behind it there is still no clear agreement as to what this dazzling term actually stands for. Save for few exceptions no definitions have as yet been offered for this instrument from the realm of science and politics. The present article therefore attempts to approach the concept of ownership unbundling, presenting possible options for its implementation. Based on these options it then goes on to address the legality of such measures under European and German constitutional law.

  8. The role of cross-listing, foreign ownership and state ownership in dividend policy in an emerging market

    Institute of Scientific and Technical Information of China (English)

    Kevin C.K.Lam; Heibatollah Sami; Haiyan Zhou

    2012-01-01

    In this paper, we investigate if dividend policy is influenced by ownership type.Within the dividend literature, dividends have a signaling role regarding agency costs, such that dividends may diminish insider conflicts(reduce free cash flow) or may be used to extract cash from firms(tunneling effect)- which could be predominant in emerging markets. We expect firms with foreign ownership and those that are listed in overseas markets to have different dividend policies and practices than those that are not, and firms with more state ownership and less individual ownership to be more likely to pay cash dividends and less likely to pay stock dividends. Using firms from an emerging economy(China), we examine whether these effects exist in corporate dividend policy and practice. We find that both foreign ownership and cross-listing have significant negative effects on cash dividends, consistent with the signaling effect and the notion of reduced tunneling activities for firms with the ability to raise capital from outside of China. Consistent with the tunneling effect, we find that firms with higher state ownership tend to pay higher cash dividends and lower stock dividends, while the opposite is true for public(individual) ownership.Further analysis shows that foreign ownership mediates the effect of state ownership on dividend policy. Our results have significant implications for researchers, investors, policy makers and regulators in emerging markets.

  11. Charity care in nonprofit urban hospitals: analysis of the role of size and ownership type in Washington State for 2011.

    Science.gov (United States)

    Coyne, Joseph S; Ogle, Natalie M; McPherson, Sterling; Murphy, Sean; Smith, Gary J; Davidson, Gregg Agustín

    2014-01-01

    Nonprofit hospitals are expected to serve their communities as charitable organizations in exchange for the tax exemption benefits they receive. With the passage into law of the Affordable Care Act, additional guidelines were generated in 2010 to ensure nonprofit hospitals are compliant. Nonetheless, the debate continues on whether nonprofit hospitals provide adequate charity care to their patient population. In this study, charity care provided by 29 Washington State nonprofit urban hospitals was examined for 2011 using financial data from the Washington State Department of Health. Charity care levels were compared to both income tax savings and gross revenues to generate two financial ratios that were analyzed according to hospital bed size and nonprofit ownership type. For the first ratio, 97% of the hospitals (28 of 29) were providing charity care in greater amounts than the tax savings they accrued. The average ratio value using total charity care and total income tax savings of all the hospitals in the study was 6.10, and the median value was 3.46. The nonparametric Kruskal-Wallis test results by bed size and nonprofit ownership type indicate that ownership type has a significant effect on charity care to gross revenue ratios (p = .020). Our analysis indicates that church-owned hospitals had higher ratios of charity care to gross revenues than did the other two ownership types--government and voluntary--in this sample. Policy implications are offered and further studies are recommended to analyze appropriate levels of charity care in nonprofit hospitals given new requirements for maintaining a hospital's tax-exempt status.

  13. The Importance of Fostering Ownership During Medical Training.

    2016-09-01

    There is a need to consider the impact of the new resident-hours regulations on the variety of aspects of medical education and patient care. Most existing literature about this subject has focused on the role of fatigue in resident performance, education, and health care delivery. However, there are other possible consequences of these new regulations, including a negative impact on decision ownership. Our main assumption of is that increased shift work in medicine can decrease ownership of treatment decisions and impact negatively on quality of care. We review some potential components of decision ownership in treatment context and suggest possible ways in which the absence of decision ownership may decrease the quality of medical decision making. The article opens with the definition of decision ownership and the overview of some contextual factors that may contribute to the development of ownership in medical residency. The following section discusses decision ownership in medical care from the perspective of "diffusion of responsibility." We question the quality of choices made within narrow decisional frames. We also compare isolated and interrelated choices, assuming that residents make more isolated decisions during their shifts. Lastly, we discuss the consequences of decreased decision ownership impacting the delivery of health care. PMID:27471927

    2011-09-01

    Full Text Available This study examines the association between ownership structure and voluntary disclosure levels in the 2007 annual report of 94 samples of Bangladeshi listed companies. Ownership structure is provided by management ownership and institutional ownership. Using agency theory, it is argued that firms with higher management ofownership structure may disclose less information and higher institutional of ownership structure may disclose more information to shareholders through voluntary disclosure. It is because the determined ownership structure provides firms lower incentives tovoluntarily disclose information to meet the needs of non-dispersed shareholders .Agency theory is utilized as the underlying theoretical framework of voluntary disclosure. Using a unweighted relative disclosure index for measuring voluntary disclosure. The extent of voluntary disclosure level is measured using 68 items recommended by those who have professional qualifications. The result shows that the extent of corporate voluntary disclosures is negatively associated with a higher management of ownership structure and the extent of corporate voluntary disclosures is positively associated with a higher institutional ownership structure.

  5. Ownership of heritage resources in South Africa: challenges and opportunities

    Directory of Open Access Journals (Sweden)

    Ndukuyakhe Ndlovu

    2013-03-01

    Full Text Available The concept of ownership is highly political. Ownership provides power to the one legally seen as an owner or those tasked with the responsibility to protect and preserve heritage resources. This is no different when it comes to heritage resources, whose ownership is always contentious. The main reason for such contention is because ownership impacts on those who value objects in different ways. For example, the nature of access to heritage resources approved for people who may still attach spiritual values. As a direct result, the relevance of such heritage resources to such people may be brought into question, as the need to have them available to all citizens gain momentum. Heritage resources in South Africa have been subject to legislation since 1911, when the Bushmen Relics Act was passed. Since then, much other legislation and amendments have been passed over the years. They all aim to protect different kinds of heritage resources. Central to protection efforts is a decision to have the ownership of heritage resources put under the national estate. Ownership of heritage under South African heritage legislation will be discussed in this article. Drawing on case studies from southern Africa, the main aim of the article is to identify the challenges and opportunities attached to such a form of ownership. Opinions relating to the best approach to ownership of heritage resources are offered.

    1998-11-01

    Inauguration of the new political dispensation in South Africa, initiated a dynamic period in the historical development of its minerals policy. The process of substituting the current South African mineral policy framework with an acceptable `post apartheid` system, started soon after the 1994 election of the African National Congress (ANC) government. The Green Paper on a Minerals and Mining Policy for South Africa released for public discussion in February 1998, calls for radical transformation in mineral rights ownership. A shift towards exclusive state ownership of mineral rights, away from the present dual system of private and state ownership, is the most significant proposal. The current holders of mineral rights, or their nominees, who lawfully enjoyed security of tenure under past and present mineral laws are opposed to this transformation because mineral rights were often acquired at considerable cost. The situation is compounded by poor public record-keeping and passive mineral rights administration over a very long period. This paper represents a summary of the historical developments leading to the current legislative environment and forms the basis for any discussion on which future sculpturing of South Africa`s policy regarding mineral rights can take place. One cannot plan for the future without considering the past. 21 refs.

  19. Bringing indigenous ownership back to the private sector

    DEFF Research Database (Denmark)

    Kragelund, Peter

    Driven by across-the-board liberalizations and the commodity price boom, Zambia has recently experienced an upsurge in foreign ownership over key parts of its economy. Albeit investors from all over the world have sought to make the most of the current situation in Zambia, Chinese investors have...... been particularly present in all sectors of the Zambian economy. Foreign ownership, however, is not new to African societies and several African countries pursued indigenisation policies in the wake of independence to bring ownership back to their own citizens. Now indigenisation policies thrive again...

  20. Land market in Albania: Unresolved property ownership rights

    Directory of Open Access Journals (Sweden)

    Oltiana Muharremi

    2010-10-01

    Full Text Available After the Independence of Albania in 1912, property ownership has gone through major reforms. During communism many agricultural lands were seized by the Agrarian Reform Law. In 1990, with the fall of communism there was a huge demographic movement of people from villages to urban areas, where they settled in lands that were used by the Cooperatives. This created a lot of problems with previous land owners whose land was seized and given to the Cooperativa. Today there is a problem with the rights to property ownership, and legal certificates of ownership.

  16. Ownership Concentration and Market Value of European Banks

    DEFF Research Database (Denmark)

    2014-01-01

    This paper investigates the relationship between ownership concentration and market value of European banks, and the role of the institutional environment in shaping this relationship. Using GMM dynamic estimator on a sample of European banks over a 13-year period (1993–2005) we find on average...... a negative effect of ownership concentration on bank value, measured by Tobin's Q. However, this effect varies across different institutional settings; while higher ownership concentration results in a lower bank value particularly in the countries belonging to German legal family, the impact of ownership...... in Scandinavia. This in turn implies that restrictions of shareholdings in banks could alleviate governance problems in some countries, but lower bank valuation in others....

  19. Gun utopias? Firearm access and ownership in Israel and Switzerland.

    Science.gov (United States)

    Rosenbaum, Janet E

    2012-02-01

    The 2011 attempted assassination of a US representative renewed the national gun control debate. Gun advocates claim mass-casualty events are mitigated and deterred with three policies: (a) permissive gun laws, (b) widespread gun ownership, (c) and encouragement of armed civilians who can intercept shooters. They cite Switzerland and Israel as exemplars. We evaluate these claims with analysis of International Crime Victimization Survey (ICVS) data and translation of laws and original source material. Swiss and Israeli laws limit firearm ownership and require permit renewal one to four times annually. ICVS analysis finds the United States has more firearms per capita and per household than either country. Switzerland and Israel curtail off-duty soldiers' firearm access to prevent firearm deaths. Suicide among soldiers decreased by 40 per cent after the Israeli army's 2006 reforms. Compared with the United States, Switzerland and Israel have lower gun ownership and stricter gun laws, and their policies discourage personal gun ownership.

    It was suggested some years ago that Petri nets might be well suited to modeling metabolic networks, overcoming some of the limitations encountered by the use of systems employing ODEs (ordinary differential equations). Much work has been done since then which confirms this and demonstrates the usefulness of this concept for systems biology. Petri net technology is not only intuitively understood by scientists trained in the life sciences, it also has a robust mathematical foundation and provides the required degree of flexibility. As a result it appears to be a very promising approach to mode

  6. Genetic resources, biotech patents and gene ownership.

    Science.gov (United States)

    Lucchi, Nicola

    2014-01-01

    Human genetic resources are increasingly considered as ordinary commercial goods, but their value and utility go beyond the simple and immediate private profit. In contrast to other biological resources, commercial use does not focus upon the material itself but rather upon the genetic information it contains. Information goods are then usually subject to intellectual property rights, but in the biological and life science domains, property rights can have a negative influence upon the proper allocation of several goods, including genetic material or goods that are related to it. This scenario reflects the facts of recent litigations in the United States and Europe. In particular, these lawsuits have revived the debate over private ownership and control over genes. Within this context, the objective of the paper is to discuss how to recast the traditional right to access to and use of biochemical and human genetic material currently considered as part of the market framework. Looking beyond the protection of traditional public goods, the paper emphasizes the debate around the progressive commodification of human genetic resources facilitated by an improper use of intellectual property rights. Different scenarios are analyzed to evaluate alternative instruments and new regulatory approaches to avoid the private appropriation of human genetic resources and other natural assets.

  7. Disrupting Vestibular Activity Disrupts Body Ownership.

    2015-01-01

    People are more sensitive at detecting asynchrony between a self-generated movement and visual feedback concerning that movement when the movement is viewed from a first-person perspective. We call this the 'self-advantage' and interpret it as an objective measure of self. Here we ask if disruption of the vestibular system in healthy individuals affects the self-advantage. Participants performed finger movements while viewing their hand in a first-person ('self') or third-person ('other') perspective and indicated which of two periods (one with minimum delay and the other with an added delay of 33-264 ms) was delayed. Their sensitivity to the delay was calculated from the psychometric functions obtained. During the testing, disruptive galvanic vestibular stimulation (GVS) was applied in five-minute blocks interleaved with five minutes of no stimulation for a total of 40 min. We confirmed the self-advantage under no stimulation (31 ms). In the presence of disruptive GVS this advantage disappeared and there was no longer a difference in performance between perspectives. The threshold delay for the 'other' perspective was not affected by the GVS. These results suggest that an intact vestibular signal is required to distinguish 'self' from 'other' and to maintain a sense of body ownership. PMID:26595957

  8. Robust copyright protection using multiple ownership watermarks.

    Science.gov (United States)

    Li, Xiao-Wei; Lee, In-Kwon

    2015-02-01

    Generally, conventional transform (DWT and DFT, etc.) -based watermarking techniques provide only one spectrum plane for embedding the watermark, thus the embedding watermark information can be easily removed. To solve this problem, we propose an efficient cellular automata (CA) based watermarking method that CA transform (CAT) with various gateway values can provide many transform planes for watermark embedding according to various CA rules. In this paper, multiple ownership watermarks are first recorded in the form of an elemental image array (EIA), simultaneously, and then the recorded EIA as the watermark data is embedded into the CAT coefficient. An additional advantage of this proposed method is that EIA is composed of many elemental images and each elemental image has its own property of watermarks. Even though most data of elemental images are lost, the watermarks can be reconstructed from the remaining elemental images successfully. Experimental results show that the proposed technique provides good image quality and is robust in varying degree to some image processing attacks.

  9. Mask cost of ownership for advanced lithography

    Science.gov (United States)

    Muzio, Edward G.; Seidel, Philip K.

    2000-07-01

    As technology advances, becoming more difficult and more expensive, the cost of ownership (CoO) metric becomes increasingly important in evaluating technical strategies. The International SEMATECH CoC analysis has steadily gained visibility over the past year, as it attempts to level the playing field between technology choices, and create a fair relative comparison. In order to predict mask cots for advanced lithography, mask process flows are modeled using bets-known processing strategies, equipment cost, and yields. Using a newly revised yield mode, and updated mask manufacture flows, representative mask flows can be built. These flows are then used to calculate mask costs for advanced lithography down to the 50 nm node. It is never the goal of this type of work to provide absolute cost estimates for business planning purposes. However, the combination of a quantifiable yield model with a clearly defined set of mask processing flows and a cost model based upon them serves as an excellent starting point for cost driver analysis and process flow discussion.

    International Nuclear Information System (INIS)

    Gas-cooled reactors, using packed beds of small diameter coated fuel particles have been proposed for compact, high-power systems. The particulate fuel used in the tests was 800 microns in diameter, consisting of a thoria kernel coated with 200 microns of pyrocarbon. Typically, the bed of fuel particles was contained in a ceramic cylinder with porous metallic frits at each end. A dc voltage was applied to the metallic frits and the resulting electric current heated the bed. Heat was removed by passing coolant (helium or hydrogen) through the bed. Candidate frit materials, rhenium, nickel, zirconium carbide, and zirconium oxide were unaffected, while tungsten and tungsten-rhenium lost weight and strength. Zirconium-carbide particles were tested at 2000 K in H2 for 12 hours with no visible reaction or weight loss

    Full Text Available Existi ng literature has not yet defi ned a clear-cut relati onship between ownership structure and capital structure. This study aims to contribute to this controversial argument by examining the impact of internal (managerial ownership and external ownership on fi nancing preferences using the case of non-fi nancial fi rms listed on Karachi stock exchange during the period of 2008-2012. Our results suggest that the external ownership has a signifi cant eff ect on capital structure in accordance with the presence of blockholders. In contrast, the internal ownership has a complicated eff ect; it shows signifi cant positi ve and negati ve relati onship to leverage at lower and certain higher proporti on of managerial shareholding respecti vely. Besides, the combined analyses suggest that the presence of blockholders negates the impact of managerial ownership on capital structure. This implies that the presence of large and dominant shareholders in Pakistani fi rms may have caused a bias for debt fi nancing to protect their voti ng power and returns.

    2014-02-01

    Full Text Available The article analyses impact of the ownership structure on corporate management in the engineering industry of Ukraine. In order to detect impact of the structure of corporate ownership on corporate management the article uses general scientific and special methods of study: method of critical analysis and generalisation of theoretical studies, comparison method and statistical method. Analysis of engineering enterprises confirmed availability of impact of the structure of corporate ownership on corporate management. The article also shows that the engineering industry of Ukraine is characterised with the concentrated ownership structure, which has the following features: restriction of rights of minority shareholders with respect to management and control in a joint stock company; availability of corporate conflicts between majority and minority shareholders; availability of intense control of owners over management, which influences efficiency of making managerial decisions; hired managers and enterprise employees have no possibility to acquire stock of a joint stock company including in the form of bonuses and incentives; the controlling owner is interested in efficient activity of the enterprise and tries to create necessary conditions for this. The conducted studies give a possibility to establish that a share of stock that belongs to a hired executive body is smaller in those joint stock companies in which concentration of ownership is higher. The article also shows that the higher ownership concentration the higher is the probability that the owner would be a part of controlling bodies.

    Bargaining often occurs between parties with some shared interest. Partnerships, joint ventures, and cross ownership are examples. We extend standard bargaining models to allow for joint ownership. Joint ownership reduces costly bargaining disputes, as bargainers’ interests are more aligned. We then test the theory with collective bargaining data, where employee stock ownership plans (ESOPs) are the source of joint ownership. The theory predicts that ESOPs will lead to a reduction in strike i...

    2007-02-01

    Space flight has been shown to result in altered immune responses. The current study was designed to investigate this possibility by using the bed rest model of some space flight conditions. A large number of women are included as subjects in the study. The hypothesis being tested is: 60 days head-down tilt bed rest of humans will affect the immune system and resistance to infection. Blood, urine and saliva samples will be obtained from bed rest subjects prior to, at intervals during, and after completion of 60 days of head-down tilt bed rest. Leukocyte blastogenesis, cytokine production and virus reactivation will be assessed. The ability of the subjects to respond appropriately to immunization with the neoantigen bacteriophage φX-174 will also be determined. Bed rest is being carried out at MEDES, Toulouse France, and the University of Texas Medical Branch, Galveston, TX. The studies to be carried out in France will also allow assessment of the effects of muscle/bone exercise and nutritional countermeasures on the immune system in addition to the effects of bed rest.

  18. On the structure of turbulent gravel bed flow: Implications for sediment transport

    Mohajeri, Seyed Hossein; Righetti, Maurizio; Wharton, Geraldene; Romano, Giovanni Paolo

    2016-06-01

    The main objective of this study was to examine the turbulent flow field over gravel particles as a first step towards understanding sediment transport in a gravel bed river. Specifically, the vertical momentum flux in gravel bed turbulent flow was investigated with particular attention to the near-bed region. Spatial organization of vertical momentum flux was studied with stereoscopic Particle Image Velocimetry (PIV) measurements in a horizontal layer 1mm above the gravel crests. The vertical momentum flux through the water column was described with digital PIV measurements in three vertical planes. The data showed that near the gravel bed, net turbulent momentum flux spatially varies with respect to bed topography. Analysis of the vertical velocity data revealed that near the gravel particle crests, there is a significant net vertical form-induced momentum flux approximately with the same order of magnitude as the net vertical turbulent momentum flux. Above the crests, total net vertical momentum flux is positive. However, below the crests, despite noticeable positive form-induced momentum flux, total net vertical momentum flux is negative. Results of quadrant analysis show that variation of turbulent net vertical momentum flux through water column is in agreement with prevalence of upward movement of low velocity flow (known as ejection) above gravel crests and downward movement of high velocity flow (known as sweep) below gravel crests. Below gravel crests (- 0.1 particles but their contribution is not sufficient to move fine particles in the longitudinal direction.

  6. A study of the antecedents and consequences of psychological ownership in organizational settings.

    Science.gov (United States)

    Mayhew, Melissa G; Ashkanasy, Neal M; Bramble, Tom; Gardner, John

    2007-10-01

    Psychological ownership is a feeling of possession in the absence of any formal or legal claims of ownership. In this study, the authors aimed to extend previous empirical testing of psychological ownership in work settings to encompass both job-based and organization-based psychological ownership as well as related work attitudes and behavioral outcomes. Questionnaire data from 68 employees and their managers revealed that job-based psychological ownership and organization-based psychological ownership are distinct work attitudes that are distinguishable from job satisfaction and organizational commitment. Psychological ownership predicted job satisfaction and organizational commitment and mediated the relationship between autonomy and these work attitudes. There was no support for a relationship between psychological ownership and behavioral outcomes. The authors discuss the limitations of the study and the implications of psychological ownership.

  9. Inclusion or Exclusion? Local Ownership and Security Sector Reform

    Directory of Open Access Journals (Sweden)

    Timothy Donais

    2009-10-01

    Full Text Available This paper explores the dynamics of security sector reform (SSR, a term used to refer to efforts made to reform the security structures of states emerging from conflict or authoritarianism. While "local ownership" is increasingly viewed as a necessary element of any sustainable SSR strategy, there remains a significant gap between international policy and practice in this area. In practice, the SSR agenda continues to be driven largely by international actors, with minimal input, let alone ownership, on the part of either governments or civil society within reforming states. Indeed, the notion of local ownership has come to serve as much as a disciplining mechanism as a tool to overcome exclusion in the making and execution of security policy, and the effectiveness and sustainability of SSR programming have suffered as a result. In light of this, the paper will explore both the potential for, and the limits of, rehabilitating the notion of local ownership to enable more participatory forms of SSR, and argues that any practical local ownership strategy requires a dual policy of negotiating with state actors and engaging with non-state actors.

    Full Text Available Abstract A recent study in BMC Biology has determined that the immature stage of the bed bug (the nymph signals its reproductive status to adult males using pheromones and thus avoids the trauma associated with copulation in this species. The success of this nymphal strategy of deterrence is instructive. Against the background of increasing problems with bed bugs, this research raises the question whether pheromones might be used to control them.

    Full Text Available Samples of active coke, fresh and spent after cleaning flue gases from communal waste incinerators, were investigated. The outer layers of both coke particles were separately removed by comminution in a spouted bed. The samples of both active cokes were analysed by means of densities, mercury porosimetry, and adsorption technique. Remaining cores were examined to determine the degree of consumption of coke by the sorption of hazardous emissions (SO2, HCl, and heavy metals through its bed. Differences in contamination levels within the porous structure of the particles were estimated. The study demonstrated the effectiveness of commercial active coke in the cleaning of flue gases.

    Full Text Available We examine how the level deposit insurance coverage affects bank liquidity. We also test the role of ownership in the relationship between deposit insurance coverage and bank liquidity. This study uses quarterly data of Indonesian banks from Q1:2002 - Q2:2008. We argue that the presence of explicit deposit insurance changes a bank‘s behavior in liquidity management in the form of decreasing asset liquidity. We find some evidence on the negative impact of deposit insurance coverage on bank liquidity. However, little is found on the role of ownership structure. The credibility of deposit insurance system and implicit guarantee are the main policy implications.

    Experimental study on the maximum spoutable bed height of a spout-fluid bed (cross-section of 0.3 m x 0.03 m and height of 2 m) packed with Geldart group D particles has been carried out. The effects of particle size, spout nozzle size and fluidizing gas flow rate on the maximum spoutable bed height were studied. Experimental data were compared to some published experiments and predictions. The results show that the maximum spoutable bed height of spout-fluid bed decreases with increasing particle size and spout nozzle size, which appears the same trend to that of spouted beds. The increasing of fluidizing gas flow rate leads to a sharply decrease in the maximum spoutable bed height. The existent correlations of the maximum spoutable bed height in the literature were observed to involve large discrepancies. Additionally, the flow characteristics when bed materials deeper than the maximum spoutable height were summarized. Under this condition, the spout-fluid bed operated without a stable and coherent spout or fountain assembles the characteristics of jetting fluidized bed. Besides, the mechanisms of spout termination were investigated. It was found that slugging in the spout and growth of instabilities would cause the spout termination in spout-fluid bed.

    Full Text Available The aim of this paper was to investigate the radiometric properties of coloured nets used to protect a peach cultivation. The modifications of the solar spectral distribution, mainly in the R and FR wavelength band, influence plant photomorphogenesis by means of the phytochrome and cryptochrome. The phytochrome response is characterized in terms of radiation rate in the red wavelengths (R, 600-700 nm to that in the farred radiation (FR, 700-800 nm, i.e. the R/FR ratio. The effects of the blue radiation (B, 400-500 nm is investigated by the ratio between the blue radiation and the far-red radiation, i.e. the B/FR ratio. A BLUE net, a RED net, a YELLOW net, a PEARL net, a GREY net and a NEUTRAL net were tested in Bari (Italy, latitude 41° 05’ N. Peach trees were located in pots inside the greenhouses and in open field. The growth of the trees cultivated in open field was lower in comparison to the growth of the trees grown under the nets. The RED, PEARL, YELLOW and GREY nets increased the growth of the trees more than the other nets. The nets positively influenced the fruit characteristics, such as fruit weight and flesh firmness.

    In collaboration with ANSALDO and within the frame of the European Fusion Tecnology Task N1 (Plasma Facing Components Design Studies), ENEA has performed a design an manufacturing feasibility study for the first wall of the Next European Torus (NET) during its ''physics'' operation phase. The main design specifications are average neutron wall load=1 MW/m2, peak surface heat flux=0.4 MW/m2, total number of burn pulses=1*104, average burn pulse duration=100 s, average neutron fluence=0.03 MWy/m2, structure material=AISI 316L SA, coolant=H2O at 50/100 centigrates (in/out). The reference ENEA-ANSALDO design is based on the use of flat plates coupled by microbrazing to poloidal cooling tubes. The technological development work has led to the design and manufacturing of a representative NET first wall box segment (0.65x 0.25x0.15 m) mockup which will be tested in the 190 kW Thermal Fatique Test Facility at JRC-Ispra. In this paper, we report on the various aspects of the basic experimental and theoretical investigations on the plasma-wall interactions for adequate protection of the first wall against erosion, global stress analysis of the first wall box, thecnological tests on brazed joints, and disign and manufacturing of the first wall mockup

    Logic Petri nets (LPNs) can describe and analyze batch processing functions and passing value indeterminacy in cooperative systems. Logic Petri workflow nets (LPWNs) are proposed based on LPNs in this paper. Process mining is regarded as an important bridge between modeling and analysis of data mining and business process. Workflow nets (WF-nets) are the extension to Petri nets (PNs), and have successfully been used to process mining. Some shortcomings cannot be avoided in process mining, such as duplicate tasks, invisible tasks, and the noise of logs. The online shop in electronic commerce in this paper is modeled to prove the equivalence between LPWNs and WF-nets, and advantages of LPWNs are presented. PMID:25821845

  18. ContainerProbe-Net

    International Nuclear Information System (INIS)

    ContainerProbe-Net is a global system concept for high throughput Risk Screening of inter-modal containers while they are in motion. It will have the following detection capabilities: 1. Mis-declared hazardous materials: - illegal waste exports or imports; - hazardous materials causing many annual maritime insurance claims; - accumulated pest poisons. 2. Contraband materials: - smuggled and counterfeit goods to avoid import duties and restrictions; - narcotic drugs; - weapons for criminals; - illegal immigrants. 3. Terrorism materials: - explosives and precursors - Weapons of Mass Destruction - fissile materials. The demand for this type of detection capability with high throughput has been declared by the EU, USA and other nations as a consequence of the rising policy of Civil Security. Efforts to advocate ContainerProbe-Net to both U.S.A. and EU security research administrators are progressing as the private investment base grows. ContainerProbe-Net directly addresses the 100% Risk Screening of containers requirement. Neutron interrogation of each container on a train or on an automated vehicle passing through the ContainerProbe portal will provide information about the bulk elemental composition of the contents. A burst of pulsed neutrons for a combination of prompt γ and secondary neutron emissions can provide a measured 'fingerprint' which will remain constant from the start to the end of the container's journey. A period of two seconds is available per container in order to capture data for each container on a moving train. Contents of containers are already, to some extent, registered in the export logistics databases. However these disparate systems have evolved with computer science and the needs of ports and customs authorities. Today such systems are far from complete. The global access to such registered container data and the fusion of this information with actual physical measurement data is the Network part of the concept. Risk screening implies

  1. Alternative windpower ownership structures: Financing terms and project costs

    Energy Technology Data Exchange (ETDEWEB)

    Wiser, R.; Kahn, E.

    1996-05-01

    Most utility-scale renewable energy projects in the United States are developed and financed by private renewable energy companies. Electric output is then sold to investor-owned and public utilities under long-term contracts. Limited partnerships, sale/leaseback arrangements, and project-financing have historically been the dominant forms of finance in the windpower industry, with project-finance taking the lead more recently. Although private ownership using project-finance is still the most popular form of windpower development, alternative approaches to ownership and financing are becoming more prevalent. U.S. public and investor-owned electric utilities (IOUs) have begun to participate directly in windpower projects by owning and financing their own facilities rather than purchasing windpower from independent non-utility generators (NUGs) through power purchase agreements (PPAs). In these utility-ownership arrangements, the wind turbine equipment vendor/developer typically designs and constructs a project under a turnkey contract for the eventual project owner (the utility). The utility will also frequently sign an operations and maintenance (O&M) contract with the project developer/equipment vendor. There appear to be a number of reasons for utility involvement in recent and planned U.S. wind projects. One important claim is that utility ownership and self-finance provides substantial cost savings compared to contracting with private NUGs to supply wind-generated power. In this report, we examine that assertion.

Despite strong farmer and investor demand, most land owners, especially aging farmers are reluctant to sell farmland. Generally, current land economic fundamentals are strong and highly volatile market conditions will influence farmland values and farm ownership trends.

    2006-01-01

    With regard to rural land ownership,there exist many problems,such as absence of the subject of right,ambiguity of the def'mition of right quality,and imperfection of the taking system.To perfect the rural land ownership system in China,we should continuously take villagers' groups and villages as the subject of collective ownership and affirm the right of the members of collective organizations.In order to promote the development of the rural economy and realize the value of land,the contractual management right should be deemed as a property right and allowed to be transferred.The transferability of collective land ownership should be gradually established and the process of taking should be further normalized.Meanwhile,the farmers must receive sufficient compensation.The house site usage right is a special form of right of usufruct.To follow the principle that property should be made best use of,the house site usage right should also be transferable.

    2012-06-15

    Two net zero apartment buildings with basically similar architecture have been built in Finland, in Kuopio (latitude 62.90) and in Jaervenpaeae (latitude 60.50). The aim was to test the possibilities to build zero energy buildings at high latitudes. The Kuopio case is a student hostel and the Jaervenpaeae case a home for elderly people. The total energy demand in the buildings are 102 MWh for Kuopio and 94.3 for Jaervenpaeae corresponding to 48 and 45 and kWh/gross-m2. The buildings utilise district heat and are connected to the local grid. The renewable energy production bases in the Kuopio case on solar heat and photovoltaics. The Kuopio building has been finished in 2010 and the Jaervenpaeae building in 2011. (orig.)

  1. Drift and ownership towards a distant virtual body

    Directory of Open Access Journals (Sweden)

    Ausias ePomes

    2013-12-01

    Full Text Available In body ownership illusions participants feel that a mannequin or virtual body (VB is their own. Earlier results suggest that body ownership over a body seen from behind in extra-personal space is possible when the surrogate body is visually stroked and tapped on its back, while spatially and temporal synchronous tactile stimulation is applied to the participant’s back. This result has been disputed with the claim that the results can be explained by self-recognition rather than somatic body ownership. We carried out an experiment with 30 participants in a between-groups design. They all saw the back of a VB 1.2m in front, that moved in real-time determined by upper body motion capture. All felt tactile stimulation on their back, and for 15 of them this was spatially and temporally synchronous with stimulation that they saw on the back of the VB, but asynchronous for the other 15. After 3 minutes a revolving fan above the VB descended and stopped at the position of the VB neck. A questionnaire assessed referral of touch to the VB, body ownership, the illusion of drifting forwards towards the VB, and the VB drifting backwards. Heart rate deceleration (HRD and the amount of head movement during the threat period were used to assess the response to the threat from the fan. Results showed that although referral of touch was significantly greater in the synchronous condition than the asynchronous, there were no other differences between the conditions. However, a further multivariate analysis revealed that in the visuotactile synchronous condition HRD and head movement increased with the illusion of forward drift and decreased with backwards drift. Body ownership contributed positively to these drift sensations. Our conclusion is that the setup results in a contradiction - somatic feelings associated with a distant body - that the brain attempts to resolve by generating drift illusions that would make the two bodies coincide.

    International Nuclear Information System (INIS)

    This guidebook is the first of its kind: A focused look at coal-bed methane in a large Rocky Mountain Laramide basin. The papers in this volume cover every aspect of coal-bed methane in the San Juan Basin, including: The geology, environments of deposition, and geometry of the coal beds that contain the resource; the origin and migration history of the gas; basin-wide resource estimates; the engineering aspects of getting the gas out of the ground; the marketing and economics of producing coal-bed methane in the San Juan Basin; the legal ownership of the gas; state regulations governing well spacing and field rules; disposal of produced water; and land and mineral ownership patterns in the northern part of the basin. Also included are detailed papers on all of the major coal-bed methane fields in the basin, and in a paper on the history of Fruitland gas production, a discussion of most of the not-so-major fields. A small section of the book deals with geophysical methods, as yet still experimental, for surface detection of underground hydrocarbon resources.

  5. Bed Rest Muscular Atrophy

    Science.gov (United States)

    Greenleaf, John E.

    2000-01-01

    A major debilitating response from prolonged bed rest (BR) is muscle atrophy, defined as a "decrease in size of a part of tissue after full development has been attained: a wasting away of tissue as from disuse, old age, injury or disease". Part of the complicated mechanism for the dizziness, increased body instability, and exaggerated gait in patients who arise immediately after BR may be a result of not only foot pain, but also of muscular atrophy and associated reduction in lower limb strength. Also, there seems to be a close association between muscle atrophy and bone atrophy. A discussion of many facets of the total BR homeostatic syndrome has been published. The old adage that use determines form which promotes function of bone (Wolff's law) also applies to those people exposed to prolonged BR (without exercise training) in whom muscle atrophy is a consistent finding. An extreme case involved a 16-year-old boy who was ordered to bed by his mother in 1932: after 50 years in bed he had "a lily-white frame with limbs as thin as the legs of a ladder-back chair". These findings emphasize the close relationship between muscle atrophy and bone atrophy. In addition to loss of muscle mass during deconditioning, there is a significant loss of muscle strength and a decrease in protein synthesis. Because the decreases in force (strength) are proportionately greater than those in fiber size or muscle cross-sectional area, other contributory factors must be involved; muscle fiber dehydration may be important.

  6. Coal Bed Methane Primer

    Energy Technology Data Exchange (ETDEWEB)

    Dan Arthur; Bruce Langhus; Jon Seekins

    2005-05-25

    During the second half of the 1990's Coal Bed Methane (CBM) production increased dramatically nationwide to represent a significant new source of income and natural gas for many independent and established producers. Matching these soaring production rates during this period was a heightened public awareness of environmental concerns. These concerns left unexplained and under-addressed have created a significant growth in public involvement generating literally thousands of unfocused project comments for various regional NEPA efforts resulting in the delayed development of public and fee lands. The accelerating interest in CBM development coupled to the growth in public involvement has prompted the conceptualization of this project for the development of a CBM Primer. The Primer is designed to serve as a summary document, which introduces and encapsulates information pertinent to the development of Coal Bed Methane (CBM), including focused discussions of coal deposits, methane as a natural formed gas, split mineral estates, development techniques, operational issues, producing methods, applicable regulatory frameworks, land and resource management, mitigation measures, preparation of project plans, data availability, Indian Trust issues and relevant environmental technologies. An important aspect of gaining access to federal, state, tribal, or fee lands involves education of a broad array of stakeholders, including land and mineral owners, regulators, conservationists, tribal governments, special interest groups, and numerous others that could be impacted by the development of coal bed methane. Perhaps the most crucial aspect of successfully developing CBM resources is stakeholder education. Currently, an inconsistent picture of CBM exists. There is a significant lack of understanding on the parts of nearly all stakeholders, including industry, government, special interest groups, and land owners. It is envisioned the Primer would being used by a variety of

    Full Text Available The complexity of the study of tropospheric ozone lies in the fact that it is a secondary pollutant. It is not emitted by a source, instead its concentration in the air depends on other compounds (especially the nitrogen oxides emitted by motor vehicles and the volatile organic compounds emitted by the industry and the vegetation and meteorological factors (especially solar radiation and temperature. The European legislation compells to make measurements of the tropospheric ozone due to its effects on people (fatigue, irritation of the mucous membranes, aggravation of asthma ... and on environment (decrease of the production of cereals, synergy with plagues .... The measuring net in Catalonia belongs to the Department of Environment and Housing (DMAH. It has a pyramidal structure and it allows a surveillance to notify in case of exceeding a certain threshold. From the registered data of last years it is shown that the number of incidences is related to meteorology. They are more frequent during afternoon and the behaviour of this pollutant is different according to the proximity of the point of measurement to the sources of its precursors.

  12. A Small Universal Petri Net

    Directory of Open Access Journals (Sweden)

    Dmitry A. Zaitsev

    2013-09-01

    Full Text Available A universal deterministic inhibitor Petri net with 14 places, 29 transitions and 138 arcs was constructed via simulation of Neary and Woods' weakly universal Turing machine with 2 states and 4 symbols; the total time complexity is exponential in the running time of their weak machine. To simulate the blank words of the weakly universal Turing machine, a couple of dedicated transitions insert their codes when reaching edges of the working zone. To complete a chain of a given Petri net encoding to be executed by the universal Petri net, a translation of a bi-tag system into a Turing machine was constructed. The constructed Petri net is universal in the standard sense; a weaker form of universality for Petri nets was not introduced in this work.

  15. The birthdate effect: an extension of the Mere Ownership Effect.

    Science.gov (United States)

    Nickell, Gary; Pederson, Katie; Rossow, Cassie

    2003-02-01

    Studies have shown that attributes or variables associated with oneself are liked or preferred more compared to similar attributes unrelated to the self. Nuttin found in 1985 that people tend to prefer the letters that occur in their own names more than the letters that do not occur in their names. This name-letter-effect was later explained as a more general "mere ownership effect." The present purpose was to test whether the Mere Ownership Effect generalizes to a person's evaluation of their birthdate (month and year). 83 participants evaluated a variety of dates and objects. As expected, participants showed a significantly more positive evaluation of their own birth month and year than to their nonbirth months and years.

  16. For the greater goods? Ownership rights and utilitarian moral judgment.

    Science.gov (United States)

    Millar, J Charles; Turri, John; Friedman, Ori

    2014-10-01

    People often judge it unacceptable to directly harm a person, even when this is necessary to produce an overall positive outcome, such as saving five other lives. We demonstrate that similar judgments arise when people consider damage to owned objects. In two experiments, participants considered dilemmas where saving five inanimate objects required destroying one. Participants judged this unacceptable when it required violating another's ownership rights, but not otherwise. They also judged that sacrificing another's object was less acceptable as a means than as a side-effect; judgments did not depend on whether property damage involved personal force. These findings inform theories of moral decision-making. They show that utilitarian judgment can be decreased without physical harm to persons, and without personal force. The findings also show that the distinction between means and side-effects influences the acceptability of damaging objects, and that ownership impacts utilitarian moral judgment. PMID:24972369

  17. Pet Ownership and Evacuation Prior to Hurricane Irene.

    Hunt, Melissa G; Bogue, Kelsey; Rohrbaugh, Nick

    2012-01-01

    Pet ownership has historically been one of the biggest risk factors for evacuation failure prior to natural disasters. The forced abandonment of pets during Hurricane Katrina in 2005 made national headlines and led to the passage of the Pet Evacuation and Transportation Standards Act (PETS, 2006) which mandated local authorities to plan for companion animal evacuation. Hurricane Irene hit the East Coast of the United States in 2011, providing an excellent opportunity to examine the impact of the PETS legislation on frequency and ease of evacuation among pet owners and non-pet owners. Ninety pet owners and 27 non-pet owners who lived in mandatory evacuation zones completed questionnaires assessing their experiences during the hurricane and symptoms of depression, PTSD, dissociative experiences, and acute stress. Pet ownership was not found to be a statistical risk factor for evacuation failure. However, many pet owners who failed to evacuate continue to cite pet related reasons. PMID:26487162

  19. First possession, history, and young children's ownership judgments.

    Friedman, Ori; Van de Vondervoort, Julia W; Defeyter, Margaret A; Neary, Karen R

    2013-01-01

    It is impossible to perceive who owns an object; this must be inferred. One way that children make such inferences is through a first possession bias--when two agents each use an object, children judge the object belongs to the one who used it first. Two experiments show that this bias does not result from children directly inferring ownership from first possession; the experiments instead support an alternative account according to which the first possession bias reflects children's historical reasoning. In Experiment 1, eighty-five 3- to 5-year-olds only based inferences on first possession when it was informative about the past. In Experiment 2, thirty-two 5-year-olds based ownership judgments on testimony about past contact, while disregarding testimony about future contact.

  20. Interpreting cost of ownership for mix-and-match lithography

    Science.gov (United States)

    Levine, Alan L.; Bergendahl, Albert S.

    1994-05-01

    Cost of ownership modeling is a critical and emerging tool that provides significant insight into the ways to optimize device manufacturing costs. The development of a model to deal with a particular application, mix-and-match lithography, was performed in order to determine the level of cost savings and the optimum ways to create these savings. The use of sensitivity analysis with cost of ownership allows the user to make accurate trade-offs between technology and cost. The use and interpretation of the model results are described in this paper. Parameters analyzed include several manufacturing considerations -- depreciation, maintenance, engineering and operator labor, floorspace, resist, consumables and reticles. Inherent in this study is the ability to customize this analysis for a particular operating environment. Results demonstrate the clear advantages of a mix-and-match approach for three different operating environments. These case studies also demonstrate various methods to efficiently optimize cost savings strategies.

  1. NET remote workstation

    International Nuclear Information System (INIS)

    The goal of this NET study was to define the functionality of a remote handling workstation and its hardware and software architecture. The remote handling workstation has to fulfill two basic functions: (1) to provide the man-machine interface (MMI), that means the interface to the control system of the maintenance equipment and to the working environment (telepresence) and (2) to provide high level (task level) supporting functions (software tools) during the maintenance work and in the preparation phase. Concerning the man-machine interface, an important module of the remote handling workstation besides the standard components of man-machine interfacing is a module for graphical scene presentation supplementing viewing by TV. The technique of integrated viewing is well known from JET BOOM and TARM control using the GBsim and KISMET software. For integration of equipment dependent MMI functions the remote handling workstation provides a special software module interface. Task level support of the operator is based on (1) spatial (geometric/kinematic) models, (2) remote handling procedure models, and (3) functional models of the equipment. These models and the related simulation modules are used for planning, programming, execution monitoring, and training. The workstation provides an intelligent handbook guiding the operator through planned procedures illustrated by animated graphical sequences. For unplanned situations decision aids are available. A central point of the architectural design was to guarantee a high flexibility with respect to hardware and software. Therefore the remote handling workstation is designed as an open system based on widely accepted standards allowing the stepwise integration of the various modules starting with the basic MMI and the spatial simulation as standard components.

    Hospitals often incur substantial hidden costs associated with service agreements that they enter into with original equipment manufacturers at the time of equipment purchase. Hospitals should perform an analysis of the total cost of ownership (TCO) of their organizations' medical equipment to identify opportunities for performance improvement and savings. The findings of the TCO analysis can point to areas where clinical engineering service management can be improved through investments in technology, training, and teamwork. PMID:24968636

  7. Efficiency, ownership, and financing of hospitals: the case of Austria.

    Science.gov (United States)

    Czypionka, Thomas; Kraus, Markus; Mayer, Susanne; Röhrling, Gerald

    2014-12-01

    While standard economic theory posits that privately owned hospitals are more efficient than their public counterparts, no clear conclusion can yet be drawn for Austria in this regard. As previous Austrian efficiency studies rely on data from the 1990s only and are based on small hospital samples, the generalizability of these results is questionable. To examine the impact of ownership type on efficiency, we apply a Data Envelopment Analysis which extends the existing literature in two respects: first, it evaluates the efficiency of the Austrian acute care sector, using data on 128 public and private non-profit hospitals from the year 2010; second, it additionally focusses on the inpatient sector alone, thus increasing the comparability between hospitals. Overall, the results show that in Austria, private non-profit hospitals outperform public hospitals in terms of technical efficiency. A multiple regression analysis confirms the significant association between efficiency and ownership type. This conclusive result contrasts some international evidence and can most likely be attributed to differences in financial incentives for public and private non-profit hospitals in Austria. Therefore, by drawing on the example of the Austrian acute care hospital sector and existing literature on the German acute care hospital sector, we also discuss the impact of hospital financing systems and their incentives on efficiency. This paper thus also aims at providing a proof of principle, pointing out the importance of the respective market conditions when internationally comparing hospital efficiency by ownership type.

  8. Market risks and oilfield ownership - Refining oil and gas disclosures

    International Nuclear Information System (INIS)

    Market risk exposures of balance sheet asset values are becoming an increasingly important accounting issue. In oil and gas, oilfield exposures to oil prices are specific and contractual, presenting a contingency problem for investors, financial analysts, standard setting bodies and government agencies. Our paper uses an extensive sample of 292 oilfields to provide evidence that the US Securities and Exchange Commission (SEC) supplementary disclosures do not capture the price sensitivities of oil and gas disclosures implicit in the two main forms of oilfield ownership, concession and production sharing contracts (PSCs). Current asset disclosures neither distinguish between global variations in oilfield ownership terms, nor on market risk implications for the value of oilfield assets. Importantly, we show that unlike concessions, reserve and production disclosures vary in response to oil price movements for PSC regimes. Our results highlight the need to differentiate PSC disclosures from concession fields, and to fully reflect price risks implicit in oilfield ownership contracts. We extend findings by Rajgopal [1999. Early evidence on the informativeness of the SEC's market risk disclosures: the case of commodity price risk exposure of oil and gas producers. The Accounting Review 74, 251-280] and propose refinements to capture market risk in financial reporting. (author)

  9. Variability of bed drag on cohesive beds under wave action

    Science.gov (United States)

    Safak, Ilgar

    2016-01-01

    Drag force at the bed acting on water flow is a major control on water circulation and sediment transport. Bed drag has been thoroughly studied in sandy waters, but less so in muddy coastal waters. The variation of bed drag on a muddy shelf is investigated here using field observations of currents, waves, and sediment concentration collected during moderate wind and wave events. To estimate bottom shear stress and the bed drag coefficient, an indirect empirical method of logarithmic fitting to current velocity profiles (log-law), a bottom boundary layer model for combined wave-current flow, and a direct method that uses turbulent fluctuations of velocity are used. The overestimation by the log-law is significantly reduced by taking turbulence suppression due to sediment-induced stratification into account. The best agreement between the model and the direct estimates is obtained by using a hydraulic roughness of 10  m in the model. Direct estimate of bed drag on the muddy bed is found to have a decreasing trend with increasing current speed, and is estimated to be around 0.0025 in conditions where wave-induced flow is relatively weak. Bed drag shows an increase (up to fourfold) with increasing wave energy. These findings can be used to test the bed drag parameterizations in hydrodynamic and sediment transport models and the skills of these models in predicting flows in muddy environments.

  10. Analysis of Product Sampling for New Product Diffusion Incorporating Multiple-Unit Ownership

    Directory of Open Access Journals (Sweden)

    Zhineng Hu

    2014-01-01

    Full Text Available Multiple-unit ownership of nondurable products is an important component of sales in many product categories. Based on the Bass model, this paper develops a new model considering the multiple-unit adoptions as a diffusion process under the influence of product sampling. Though the analysis aims to determine the optimal dynamic sampling effort for a firm and the results demonstrate that experience sampling can accelerate the diffusion process, the best time to send free samples is just before the product being launched. Multiple-unit purchasing behavior can increase sales to make more profit for a firm, and it needs more samples to make the product known much better. The local sensitivity analysis shows that the increase of both external coefficients and internal coefficients has a negative influence on the sampling level, but the internal influence on the subsequent multiple-unit adoptions has little significant influence on the sampling. Using the logistic regression along with linear regression, the global sensitivity analysis gives a whole analysis of the interaction of all factors, which manifests the external influence and multiunit purchase rate are two most important factors to influence the sampling level and net present value of the new product, and presents a two-stage method to determine the sampling level.

    We describe an efficient mix-net. Its efficiency is based on a novel method, double encryption. We use a variant of "repetitive robustness", introduced by Jakobsson, to achieve robustness. The notion of double encryption enables us to avoid the large number of proofs of knowledge required in most mix-net constructions. For a large number n of senders each mix-center in our mix-net computes approximately 25n exponentiations in real time, which also gives the approximate execution time of t...

  14. Numerical Simulations of the Effects of a Tidal Turbine Array on Near-Bed Velocity and Local Bed Shear Stress

    Directory of Open Access Journals (Sweden)

    Philip A. Gillibrand

    2016-10-01

    Full Text Available We apply a three-dimensional hydrodynamic model to consider the potential effects of energy extraction by an array of tidal turbines on the ambient near-bed velocity field and local bed shear stress in a coastal channel with strong tidal currents. Local bed shear stress plays a key role in local sediment dynamics. The model solves the Reynold-averaged Navier-Stokes (RANS equations on an unstructured mesh using mixed finite element and finite volume techniques. Tidal turbines are represented through an additional form drag in the momentum balance equation, with the thrust imparted and power generated by the turbines being velocity dependent with appropriate cut-in and cut-out velocities. Arrays of 1, 4 and 57 tidal turbines, each of 1.5 MW capacity, were simulated. Effects due to a single turbine and an array of four turbines were negligible. The main effect of the array of 57 turbines was to cause a shift in position of the jet through the tidal channel, as the flow was diverted around the tidal array. The net effect of this shift was to increase near-bed velocities and bed shear stress along the northern perimeter of the array by up to 0.8 m·s−1 and 5 Pa respectively. Within the array and directly downstream, near-bed velocities and bed shear stress were reduced by similar amounts. Changes of this magnitude have the potential to modify the known sand and shell banks in the region. Continued monitoring of the sediment distributions in the region will provide a valuable dataset on the impacts of tidal energy extraction on local sediment dynamics. Finally, the mean power generated per turbine is shown to decrease as the turbine array increased in size.

  15. The use of mosquito nets and the prevalence of Plasmodium falciparum infection in rural South Central Somalia.

    Directory of Open Access Journals (Sweden)

    Abdisalan M Noor

    Full Text Available BACKGROUND: There have been resurgent efforts in Africa to estimate the public health impact of malaria control interventions such as insecticide treated nets (ITNs following substantial investments in scaling-up coverage in the last five years. Little is known, however, on the effectiveness of ITN in areas of Africa that support low transmission. This hinders the accurate estimation of impact of ITN use on disease burden and its cost-effectiveness in low transmission settings. METHODS AND PRINCIPAL FINDINGS: Using a stratified two-stage cluster sample design, four cross-sectional studies were undertaken between March-June 2007 across three livelihood groups in an area of low intensity malaria transmission in South Central Somalia. Information on bed net use; age; and sex of all participants were recorded. A finger prick blood sample was taken from participants to examine for parasitaemia. Mantel-Haenzel methods were used to measure the effect of net use on parasitaemia adjusting for livelihood; age; and sex. A total of 10,587 individuals of all ages were seen of which 10,359 provided full information. Overall net use and parasite prevalence were 12.4% and 15.7% respectively. Age-specific protective effectiveness (PE of bed net ranged from 39% among <5 years to 72% among 5-14 years old. Overall PE of bed nets was 54% (95% confidence interval 44%-63% after adjusting for livelihood; sex; and age. CONCLUSIONS AND SIGNIFICANCE: Bed nets confer high protection against parasite infection in South Central Somalia. In such areas where baseline transmission is low, however, the absolute reductions in parasitaemia due to wide-scale net use will be relatively small raising questions on the cost-effectiveness of covering millions of people living in such settings in Africa with nets. Further understanding of the progress of disease upon infection against the cost of averting its consequent burden in low transmission areas of Africa is therefore required.

    Although several alternative definitions exist, a Net-Zero Energy Building (Net ZEB) can be succinctly described as a grid-connected building that generates as much energy as it uses over a year. The “net-zero” balance is attained by applying energy conservation and efficiency measures...... and by incorporating renewable energy systems. While based on annual balances, a complete description of a Net ZEB requires examining the system at smaller time-scales. This assessment should address: (a) the relationship between power generation and building loads and (b) the resulting interaction with the power grid....... This paper presents and categorizes quantitative indicators suitable to describe both aspects of the building’s performance. These indicators, named LMGI - Load Matching and Grid Interaction indicators, are easily quantifiable and could complement the output variables of existing building simulation tools...

  5. Ownership Structure, Financial Decisions, and Institutional Setting: An International Analysis through Simultaneous Equations

    Directory of Open Access Journals (Sweden)

    Félix J. López-Iturriaga

    2012-01-01

    Full Text Available We analyze the mutual relations among firms’ capital structure, ownership structure, and valuation. Through the estimation of a system of simultaneous equations for a sample of 1,130 firms from 16 countries from both the common law and the civil law environments, our results confirm the differential effect of ownership structure on firms’ value in each setting. Whereas in civil law firms the higher ownership concentration results in an entrenchment and an alignment effect, in the common law firms higher ownership concentration increases the value of the firm. Second, we corroborate the endogeneity of ownership structure since we find that ownership structure is affected by the value of the firm and by the capital structure. Third, our results suggest that corporate finance decisions are taken simultaneously with other mechanisms of corporate governance and conditional on firms’ valuation.

    Full Text Available This paper investigates the impacts of Taipei Mass Rapid Transit (MRT system on household car ownership and analyses how socioeconomic characteristics affect household car ownership. We employ a difference-in-difference (DID strategy integrated with generalized Poisson regression models to examine the effects of MRT. The results are as follows: first, the establishment of Taipei MRT significantly reduced the level of household car ownership. Expanding the network of MRT system can be a feasible policy to control car ownership. Second, the levels of household car ownership are related to household’s socioeconomic characteristics. Third, households with high dependence on public transport own fewer cars after Taipei MRT began operation. Hence, the traffic authority should adopt more effective methods to encourage public transit use in order to decrease household car ownership.

    2015-01-01

    In undergraduate research experiences, student development of an identity as a scientist is coupled to their sense of ownership of their research projects. As a a first step towards studying similar connections in physics laboratory courses, we investigate student ownership of projects in a lasers-based upper-division course. Students spent the final seven weeks of the semester working in groups on final projects of their choosing. Using data from the Project Ownership Survey and weekly student reflections, we investigate student ownership as it relates to students' personal agency, self-efficacy, peer interactions, and complex affective responses to challenges and successes. We present evidence of students' project ownership in an upper-division physics lab. Additionally, we find that there is a complex relationship between student affect and their sense of ownership.

  8. Wall-to-bed heat transfer in circulating fluidized beds

    Fox, W.B.; Grewal, N.S.; Moen, D.A. [Univ. of North Dakota, Grand Forks, ND (United States). Mechanical Engineering Dept.

    1999-05-01

    Circulating fluidized beds (CFBs) have become increasingly important in recent years for coal combustion and gas-solid reactions. Here, heat transfer from the wall of a circulating fluidized bed to the fast bed suspension has been investigated for several materials. The range of investigation includes dense and dilute phase fast fluidization and pneumatic transport. The overall heat transfer coefficient was found to be a function mainly of cross-sectional average suspension density. Effects of superficial velocity and solids mass flux were obscured by their interrelationship to the suspension density. Two models from the literature are evaluated using present and published data.

    We analyze how ownership concentration and type, and board independence are related to corporate social performance (CSP). Drawing from agency and team production theories, we argue that the distribution of costs and benefits to shareholders and other stakeholders is crucial to understand what drives CSP. We analyze an international panel of listed firms and reveal that CSP is negatively related to ownership concentration, but positively to board independence. Furthermore, the ownership type ...

    This paper offers empirical evidence for the Spanish case on the hypothesis that public ownership may be a determinant of a firm's performance. Two alternative definitions of efficiency are proposed: relative productivity and profitability. The role of ownership is tested, conditioning for the degree of competition, the financial position of the firm and labour quality. The data used is a sample of Spanish manufacturing firms for the period 1983-1996. The results show that ownership is not a ...

  18. Bank Regulatory Capital Adjustment and Ultimate Ownership Structure: Evidence from European Commercial Banks

    OpenAIRE

    Lepetit, Laetitia; Tarazi, Amine; Zedek, Nadia

    2012-01-01

    We empirically investigate whether a bank's decision to recapitalize is influenced by its ownership characteristics, particularly the separation between voting and cash-flow rights of the bank's ultimate owner. We use a novel hand-collected dataset on bank ultimate control and ownership structure of 442 European commercial banks to estimate an ownership- augmented capital adjustment model. We find that when the ultimate owner's voting and cash-flow rights are identical, banks actively (as opp...

  19. Ownership, Dividends, R&D and Retained Earnings - are institutional owners short-term oriented?

    OpenAIRE

    Wiberg, Daniel

    2008-01-01

    This paper investigates the link between institutional ownership and dividend policy. Utilizing a dividend payout model, which accounts for earnings trends and partial adjustments of dividends, a positive but marginally diminishing relation is found between institutional ownership and dividends. This result holds when ownership is retained through the use of control enhancing mechanisms such as vote-differentiation, instruments that induce investors to demand higher payout ratios. A positive ...

  20. French connection: interlocking directorates and the ownership-control nexus in an insider governance system

    OpenAIRE

    2013-01-01

    We reveal the non-separation of ownership and control for multiple blockholders in the French insider governance system. We show that overlapping directorships of large listed corporations are explained by their ownership connections. Both large and small stakes, from 20% to 1% of cash-flow rights or voting rights, have high explanatory power. Some shareholdings are control rather than monitoring related. We provide evidence also that cross-ownership allows CEOs to entrench themselves. Finall...
