Selected AbstractsPacific Islands Families Study: behavioral problems among two-year-old Pacific children living in New ZealandTHE JOURNAL OF CHILD PSYCHOLOGY AND PSYCHIATRY AND ALLIED DISCIPLINES, Issue 5 2007Janis Paterson Background:, The aim of this study was to determine (1) the prevalence of behavioral problems among two-year-old Pacific children living in New Zealand, (2) ethnic differences in behavioral problems, and (3) relationships between maternal and socio-demographic variables and problem child behavior. Methods:, Data were gathered from the Pacific Islands Families (PIF) Study. Mothers of a cohort of 1398 Pacific infants born in Auckland, New Zealand during 2000 were interviewed when the children were two years of age. Maternal reports (1028) of child behavior were obtained using the Child Behavior Checklist (CBCL). Results:, In the PIF cohort, 15.6% of children were in the clinical range with one or more deviant scores from the seven syndrome scales, and 14% were in the borderline range. The prevalence rate of internalizing problems was 17.1% in the clinical range and 8.9% in the borderline range. The prevalence rate of externalizing problems was 6.6% in the clinical range and 13.7% in the borderline range. The prevalence rate of total problems was 14.2% in the clinical range and 9.6% in the borderline range. Discipline and maternal education were significantly associated with elevated externalizing scores. Household size, maternal education, cultural orientation, and number of years living in New Zealand were significantly associated with internalizing scores. Child ethnicity was significantly associated with internalizing, externalizing and total problem behavior scores. In the clinical range, child ethnicity and gender were significantly associated with the prevalence of problem behavior. Conclusions:, Cross-ethnicity differences in CBCL scores were found, which illustrates the diversity in the Pacific population in New Zealand. Such findings highlight the way in which preschool behavior problems may vary within specific cultural settings and underscore the need for in-depth research to explore these unique contexts. [source] Household size and residential water demand: an empirical approach,AUSTRALIAN JOURNAL OF AGRICULTURAL & RESOURCE ECONOMICS, Issue 1 2010Fernando Arbués The effectiveness of pricing policies depends on the price elasticity of consumption. It is well documented that residential demand for water is influenced by heterogeneity associated with differences in the size of the household and socioeconomic characteristics. In this paper, we focus on household size. Our initial hypothesis is that users' sensitivity to changes in price is different depending on the number of household members. To this end, we carry out an empirical estimation of urban water demand in Zaragoza (Spain) distinguishing between households with different sizes using data at the individual level. As far as we are aware, this approach to urban residential water demand is new in the literature. The analysis suggests that all households are sensitive to prices regardless of size. A more relevant finding is that small households are more sensitive to price changes. [source] A Pivotal Moment in 50 Years of Headache History: The First American Migraine StudyHEADACHE, Issue 5 2008Stewart J. Tepper MD Objective., To describe the magnitude and distribution of the public health problem posed by migraine in the United States by examining migraine prevalence, attack frequency, and attack-related disability by gender, age, race, household income, geographic region, and urban vs rural residence. Design., In 1989, a self-administered questionnaire was sent to a sample of 15,000 households. A designated member of each household initially responded to the questionnaire. Each household member with severe headache was asked to respond to detailed questions about symptoms, frequency, and severity of headaches. Setting., A sample of households selected from a panel to be representative of the US population in terms of age, gender, household size, and geographic area. Participants., After a single mailing, 20,468 subjects (63.4% response rate) between 12 and 80 Years of age responded to the survey. Respondents and nonrespondents did not differ by gender, household income, region of the country, or urban vs rural status. Whites and the elderly were more likely to respond. Migraine headache cases were identified on the basis of reported symptoms using established diagnostic criteria. Results., In total, 17.6% of females and 5.7% of males were found to have 1 or more migraine headaches per year. The prevalence of migraine varied considerably by age and was highest in both men and women between the ages of 35 to 45 years. Migraine prevalence was strongly associated with household income; prevalence in the lowest-income group (less than $10,000) was more than 60% higher than in the 2 highest-income groups (greater than or equal to $30,000). The proportion of migraine sufferers who experienced moderate to severe disability was not related to gender, age, income, urban vs rural residence, or region of the country. In contrast, the frequency of headaches was lower in higher-income groups. Attack frequency was inversely related to disability. Conclusions., A projection to the US population suggests that 8.7 million females and 2.6 million males suffer from migraine headache with moderate to severe disability. Of these, 3.4 million females and 1.1 million males experience 1 or more attacks per month. Females between ages 30 and 49 years from lower-income households are at especially high risk of having migraines and are more likely than other groups to use emergency care services for their acute condition. [source] Quality of life and depression of people living with type 2 diabetes mellitus and those at low and high risk for type 2 diabetes: findings from the Study to Help Improve Early evaluation and management of risk factors Leading to Diabetes (SHIELD)INTERNATIONAL JOURNAL OF CLINICAL PRACTICE, Issue 4 2008S. Grandy Summary Objectives:, This study compared health-related quality of life (HRQoL) and depression among individuals with type 2 diabetes mellitus (T2D) and those at low or high risk for T2D. Methods:, Respondents in a population-based US 2004 survey reported whether they had T2D (n = 3530) or risk factors for T2D [abdominal obesity, body mass index (BMI) , 28 kg/m2, dyslipidaemia, hypertension and history of cardiovascular disease]. Respondents without T2D were stratified into low risk (0,2 risk factors, n = 5335) and high risk (3,5 risk factors, n = 5051). SF-12 version 2 (SF-12) and Patient Health Questionnaire (PHQ)-9 were used to measure HRQoL and depression. Mean scores were compared across the three groups using analysis of variance. Linear regression identified factors associated with SF-12 Physical and Mental Component Summary scores (PCS and MCS), adjusting for age, gender, race, income, geographic region, household size, BMI and group. Results:, Respondents were mostly women (60%) with mean age of 54 years. Mean PCS scores for T2D and high risk (39.5 and 41.7, respectively) were significantly lower than for low risk (50.6, p < 0.001). After adjustment, high-risk and T2D groups were associated with lower PCS and MCS scores compared with low risk group (p < 0.05). Mean PHQ-9 scores and per cent with moderate-to-severe depression were significantly higher for T2D and high risk than for low risk (p < 0.01). Conclusions:, Health-related quality of life and depression scores in T2D were similar to those at high risk, and indicated significant decrements in physical health and greater depression compared with low-risk respondents. [source] Joint estimation of information acquisition and adoption of new technologies under uncertainty,JOURNAL OF INTERNATIONAL DEVELOPMENT, Issue 4 2008Awudu Abdulai Abstract This article develops a framework to examine households' joint decision to acquire information on new technologies and the adoption of the technology in the presence of uncertainty. The empirical application involved a sample of 406 dairy farmers in Tanzania. Education, scale of production, household size, age, and liquidity constraints are hypothesized to be the determinants of information acquisition and adoption decisions. The empirical evidence indicates that information acquisition and adoption decisions are made jointly. The findings also show that human capital and scale of operation positively and significantly affect the decision to acquire information and to adopt the technology, while liquidity constraints negatively impact on the decision to adopt, as well as the extent of adoption.

Effects of Urban Spatial Structure, Sociodemographics, and Climate on Residential Water Consumption in Hillsboro, Oregon. Journal of the American Water Resources Association (JAWRA) 46(3):461-472. DOI: 10.1111/j.1752-1688.2009.00415.x Abstract:, In the Portland metropolitan area, suburban growth in cities such as Hillsboro is projected to increase as people seek affordable housing near a burgeoning metropolis. The most significant determinants for increases in water demand are population growth, climate change, and the type of urban development that occurs. This study analyzes the spatial patterns of single family residential (SFR) water consumption in Hillsboro, Oregon, at the census block scale. The following research questions are addressed: (1) What are the significant determinants of SFR water consumption in Hillsboro, Oregon? (2) Is SFR water demand sensitive to drought conditions and interannual climate variation? (3) To what magnitude do particular census blocks react to drought conditions and interannual climate variation? Using ordinary least squares multiple regression and spatial regression methods, we found that base use, representing indoor water use, is dependent on household size and that seasonal use, representing external water use is dependent on both education level and the size of the property's outdoor space. Spatial analysis techniques determined that although the water demand of the study area as a whole is not sensitive to drought conditions, certain individual census blocks do respond with a higher magnitude of water use. The most climate-sensitive census blocks tend to contain newer and larger homes, and have higher property values and more affluent and well-educated residents. [source] Mothers' citizenship status and household food insecurity among low-income children of immigrantsNEW DIRECTIONS FOR CHILD & ADOLESCENT DEVELOPMENT, Issue 121 2008Ariel Kalil Recent data have shown that children of immigrant noncitizens experience more persistent and higher levels of food insecurity than the children of citizens following welfare reform. However, little is known about the range of factors that might explain different rates of food insecurity in the different populations. In this study, the authors used national data from the Early Childhood Longitudinal Study,Kindergarten cohort to assess this question, using multivariate probit regression analyses in a low-income sample. They found that households of children (foreign and U.S.-born) with noncitizen mothers are at substantially greater risk of food insecurity than their counterparts with citizen mothers and that demographic characteristics such as being Latina, levels of maternal education, and large household size explain about half of the difference in rates. © 2008 Wiley Periodicals, Inc. [source] Labour migration and change in older people's living arrangements: the case of Kanchanaburi Demographic Surveillance System (KDSS), ThailandPOPULATION, SPACE AND PLACE (PREVIOUSLY:-INT JOURNAL OF POPULATION GEOGRAPHY), Issue 5 2008Min Qin Abstract This study involves an investigation of changes in older people's living arrangements in the context of a 4-round panel design from the Kanchanaburi Demographic Surveillance System (KDSS), Thailand. The respondents were 2320 persons aged 60 and above, who were co-residing with family members in addition to, or other than, their spouse at the time of the first round of the census. Survival analysis is used to interpret the data. Results indicate that labour migration plays an important role in changes in the living arrangements of older people. Migration increases the risk of living alone. Other demographic and socio-economic factors of importance include the marital status of older people, economic security, household assets, household size, and household members living nearby. The paper concludes by discussing policy implications of the findings. Copyright © 2008 John Wiley & Sons, Ltd. [source] Employment Polarisation in Australia,THE ECONOMIC RECORD, Issue 255 2005PETER DAWKINS Although employment levels in Australia are healthy when compared to those 20 years ago, the distribution of work across households has become more unequal. The present paper measures any polarisation of employment that has taken place in Australian households between 1982 and 2000/01. We find that employment has indeed become polarised across Australian households with most of the polarisation within-household types and not entirely reflecting changes in household size. Particularly worrying is the polarisation found in households with children. This is likely to have consequences for the well-being of future generations. [source] Vulnerability to Poverty in Papua New Guinea in 1996ASIAN ECONOMIC JOURNAL, Issue 3 2010Raghbendra Jha C21; C23; C26; I32 This paper uses cross-section data from the 1996 Papua New Guinea Household Survey to assess household vulnerability to poverty in Papua New Guinea. Vulnerability varies across regions, household size, gender and level of education of households. We use a simple empirical model that permits estimation of vulnerability to poverty assuming that households have the same conditional distribution of consumption in a stationary environment. Although this approach does not capture all dimensions of vulnerability, it at least raises the policy interest that vulnerability should be considered alongside poverty. [source] DEMOGRAPHIC DEMAND SYSTEMS WITH APPLICATION TO EQUIVALENCE SCALES ESTIMATION AND INEQUALITY ANALYSIS: THE AUSTRALIAN EVIDENCEAUSTRALIAN ECONOMIC PAPERS, Issue 3 2010PAUL BLACKLOW This paper proposes and applies an alternative demographic procedure for extending a demand system to allow for the effect of household size and composition changes, along with price changes, on expenditure allocation. The demographic procedure is applied to two recent demand functional forms to obtain their estimable demographic extensions. The estimation on pooled time series of Australian Household Expenditure Surveys yields sensible and robust estimates of the equivalence scale, and of its variation with relative prices. Further evidence on the usefulness of this procedure is provided by using it to evaluate the nature and magnitude of the inequality bias of relative price changes in Australia over a period from the late 1980s to the early part of the new millennium.

[source] Determinants of price mark-up tolerance for green electricity , lessons for environmental marketing strategies from a study of residential electricity customers in GermanyBUSINESS STRATEGY AND THE ENVIRONMENT, Issue 5 2010Torsten J. Gerpott Abstract This paper develops hypotheses on the effects of various attitudinal and perceptual variables as well as socio-demographic characteristics of residential electricity customers on an individual's willingness to pay a mark-up for electricity generated from renewable energy sources compared with the price due for electricity from conventional sources. The hypotheses are tested with data from a standardized telephone survey of 238 household electricity consumers in Germany. 53.4% of the participants are willing to pay a mark-up for green electricity. 26.1% report a price tolerance equal to a 5,10% increase in their current electricity bill. Binary logistic and ordinal regression analyses indicate that price tolerance for green electricity is particularly influenced by attitudes (1) towards environmental issues and (2) towards one's current power supplier, (3) perceptions of the evaluation of green energy by an individual's social reference groups, (4) household size and (5) current electricity bill level. The findings are used to derive suggestions for energy related informational activities of public institutions, green marketing strategies of energy companies and future consumer research regarding demand for pro-environmental goods.

[source] Household Epidemics: Modelling Effects of Early Stage VaccinationBIOMETRICAL JOURNAL, Issue 3 2009Nyimvua Shaban Abstract A Markovian susceptible , infectious , removed (SIR) epidemic model is considered in a community partitioned into households. A vaccination strategy, which is implemented during the early stages of the disease following the detection of infected individuals is proposed. In this strategy, the detection occurs while an individual is infectious and other susceptible household members are vaccinated without further delay. Expressions are derived for the influence on the reproduction numbers of this vaccination strategy for equal and unequal household sizes. We fit previously estimated parameters from influenza and use household distributions for Sweden and Tanzania census data. The results show that the reproduction number is much higher in Tanzania (6 compared with 2) due to larger households, and that infected individuals have to be detected (and household members vaccinated) after on average 5 days in Sweden and after 3.3 days in Tanzania, a much smaller difference.
