The zero-inflated regression models such as zero-inflated Poisson (ZIP), zero-inflated negative binomial (ZINB) or zero-inflated generalized Poisson (ZIGP) regression models can model the count data with excess zeros. The ZINB model can handle over-dispersed and the ZIGP model can handle the over or under-dispersed count data with excess zeros as well. Moreover, the count data may be correlated because of data collection procedure or special study design. The clustered sampling approach is one of the examples in which the correlation among subjects could be defined. In such situations, a marginal model using generalized estimating equation (GEE) approach can incorporate these correlations and lead up to the relationships at the population level. In this study, the GEE-based zero-inflated generalized Poisson regression model was proposed to fit over and under-dispersed clustered count data with excess zeros. 相似文献

Companies around the world have had mixed results in their efforts to reach customers at the base of the economic pyramid (BoP). GrameenPhone, the leading telecommunications firm in Bangladesh, has expanded its market reach while reducing poverty through an initiative that empowers the rural poor with access to the information and resources they need to start their own businesses. An outgrowth of the company's corporate social responsibility program, the GrameenPhone Community Information Centre offers an entrepreneurship business model well suited to the needs of those living and doing business in developing countries. ©2014 Wiley Periodicals, Inc. 相似文献

ABSTRACTUrinary incontinence (UI) is a common condition, especially in middle-aged and older women. UI is known to affect sexual function. Many women with UI do not consult a doctor about their condition. The aim of this study was to determine the relationship of sexual function and help seeking in postmenopausal women with urinary incontinence. This cross-sectional correlation study took place from March to May 2012. The subjects were selected by a clustered sampling method from various zones of Rasht (North of Iran). The data were collected using personal data forms, Questionnaire for Urinary Incontinence Diagnosis, Incontinence Severity Index, and Incontinence Quality of Life questionnaire. Data were analyzed by SPSS17 at the significant level of P < .05 and then were compared by parametric and nonparametric tests. A total of 313 menopausal women aged 45 to 60 years (mean 52.9) were recruited for the study. The mean sexual function score was 31.07 ± 7.52. Only 27.3% of subjects seek care for urinary incontinence. There was a significant correlation between sexual function and help seeking. The results of this study indicate that there is a significant correlation between sexual function and help seeking in postmenopausal women who participated in the present study. Health-care professionals should pay more attention to sexual symptoms of UI and make patients aware of available treatments. 相似文献

The reported ability of cysteine and cystine to bind typical arsenic oxy‐ions in water is used as a basis for a study of the potential for using a surfactant with a cysteine head‐group for selective arsenic binding and removal in an ion flotation process. Several different head‐group attachment methods are studied with cysteine and cystine and with single‐ and double‐chain surfactants. A comparison of the properties of these surfactants with some other surface‐active compounds, with groups like those on cysteine, suggest that few compounds have suitable characteristics for the efficient removal of low levels of arsenic from drinking water. An amino‐acid‐based single‐chain surfactant is synthesized by reacting cysteine with octanoyl chloride to obtain octanoyl cysteine, which is then used in a study of selective ion flotation for the removal of low levels of arsenic from drinking water. This compound has high water solubility and causes extensive foaming in a typical flotation chamber and removed 99.4–99.9% of the 5 mg L−1 arsenic present in the contaminated water in a simple, single‐stage ion flotation process, using either air or nitrogen gas. These laboratory results indicate that these surfactants can be useful in the large‐scale treatment of low‐level arsenic‐contaminated water. 相似文献

Iranian women have never represented more than 5.9% of sitting parliamentarians in the Islamic Republic of Iran. This compares poorly with relevant regional and global averages. In the lead up to the 2016 parliamentary elections, the women’s movement took action to address the low representation of women in the legislature by launching the ‘Campaign to Change the Male Face of Parliament’. The Campaign did not reach its goal of achieving 50 seats for women in the 2016–2020 Parliament. It was also subject to some criticism for effectively (or apparently) legitimising what many women view as a broken form of government unable to promote and protect women’s rights in any meaningful sense. However, the Campaign was an important exercise in democracy and had significant higher-order impacts on voter behaviour and women’s capacities. Through personal communication with three Campaign activists, this profile provides an authoritative account of the Campaign experience and its impact and significance for the future of women’s empowerment in Iran. 相似文献

The main objective of the present study is to investigate energy consumption, exergy and greenhouse gas (GHG) emissions from prune production in both the garden and plant sectors. Both energy and exergy analysis methods are used while some sustainability indicators such as the cumulative degree of perfection (CDP) and the renewability indicator (RI) as well environmental aspects are considered. The analysis is based on the actual operational data. The high energy consumption, exergy and GHG emissions are related to the post-harvest and the factory operations. Natural gas is determined to be the most effective input to energy consumption, exergy and GHG emissions in the whole process of producing prunes. Based on the sustainability indicators used, the agricultural operation of the plum production process is partially renewable while the factory operation of the prune production process is highly non-renewable. In cases where the production process of prunes includes the use of renewable energy and plum waste, CDP increases from 0.32 to 2.88 and RI from -2.16 to 0.65. The use of renewable sources in producing one ton of prune annually reduces GHG emissions by 362.55 tons and energy consumption by 7.45 TJ worldwide. The use of plum waste would also produce 402.8 TJ of energy per year. 相似文献

Since abuse screening is difficult among the elderly with dementia, detection of elder abuse is a serious issue; meanwhile, the number of available tools to assess elder abuse by caregivers is limited. The aim was to evaluate validity and reliability of the Iranian version Caregiver Abuse Screen (CASE) tool. After the translating process of the tool to the Farsi language for 236 dementia participants ≥60 years old and their informal caregivers’ from outpatient’ clinics, in a cross-sectional method then the validity, reliability and factorial structure of the CASE was evaluated. The translated Iranian version CASE reveals a good psychometric property (α = 0.868) with strong internal consistency and reliability. Some variables (depression, burden, dementia intensity, and ADLs) were associated with abuse in dementia elderly. The two-factor structure was obtained in exploratory factor analysis labeled interpersonal abuse and neglect. Generally, the Iranian version of CASE approved with sufficient validity and reliability as a suitable instrument to find the risk of elder abuse among dementia caregivers. 相似文献

AbstractAnalysis capability indices for symmetric process in normal case is obtained via maximum entropy approach of distribution function of the data. In view of it, we have perused on production processes to be in statistical control. Generally a process is capable based on capability indices when its reasonable index was more than a known threshold value. Thus by conditioning on indices, the most general distribution is found out whose parameters can be approximated by using the data of process. Also analysis via Kullback-Leibler information measure based on the above arguments is obtained in the last part of the paper. 相似文献
