A new space–time multivariate approach for environmental data analysis

Air quality control usually requires a monitoring system of multiple indicators measured at various points in space and time. Hence, the use of space–time multivariate techniques are of fundamental importance in this context, where decisions and actions regarding environmental protection should be supported by studies based on either inter-variables relations and spatial–temporal correlations. This paper describes how canonical correlation analysis can be combined with space–time geostatistical methods for analysing two spatial–temporal correlated aspects, such as air pollution concentrations and meteorological conditions. Hourly averages of three pollutants (nitric oxide, nitrogen dioxide and ozone) and three atmospheric indicators (temperature, humidity and wind speed) taken for two critical months (February and August) at several monitoring stations are considered and space–time variograms for the variables are estimated. Simultaneous relationships between such sample space–time variograms are determined through canonical correlation analysis. The most correlated canonical variates are used for describing synthetically the underlying space–time behaviour of the components of the two sets.     

Parents’ Reports of Sexual Communication With Children in Kindergarten to Grade 8

We examined factors associated with parents’ reports of three aspects of parent‐child sexual communication, quality, frequency with which parents encouraged questions, and extent of communication, on each of 10 sexual health topics. Participants were 3,413 mothers and 426 fathers with children in kindergarten to grade 8. Parents’ demographic characteristics, own sexual health education, knowledge and comfort talking about sexuality with their children, and ratings of the importance of comprehensive school‐based sex education plus child gender and grade level were uniquely related to their self‐reported sexual communication with their children, although different predictors were associated with various topics. These results highlight the need to include characteristics of parents, their children, and the communication itself in research on parent‐child sexual communication.     

Jackknifed kernel quantile estimators

A new quantile estimator is obtained by jackknifing the kernel quantile estimator. The asymptotic relative deficiency of the kernel quantile estimator relative to the jackknifed quantile estimator is investigated.     

Residential Respite Care: The Caregiver's Last Resort

Understanding the beliefs that caregivers of people with dementia have in regard to the use of residential respite may inform strategies to address low service utilisation. In this article, the application of theory in qualitative research with 36 caregivers provides insight into why most delay service use. Although some believe that service use may increase caregiving longevity, others position service use in conflict with normative values, and may hold beliefs that negative outcomes will result from utilisation. To address caregivers' beliefs to support service use, improvements are required to service promotion, as well as to models of care.     

“How Can You Retire When You Still Got a Kid in School?”: Economics of Raising Grandchildren in Rural Areas

Increasingly, grandparents are being called on to rear their grandchildren when parents are unable or unwilling to fulfill their parenting role. These grandparent caregivers often find themselves in an economic bind. Financially, most are at a stage in life where they are looking toward retirement and reduced family spending and are unprepared for their new economic reality as second-time-around caregivers. Here, we use a framework of family financial well-being to examine the economic consequences of rearing grandchildren. Based on family life interviews with 26 grandfamilies residing in Montana, we explore the challenges grandparents experience generating and shifting income streams in later life, the variability in received income, and the array of expected and unexpected expenses incurred as a result of taking in their grandchildren. As custodial grandparents strive for financial well-being, there are few resources—especially in rural areas—to help them navigate these new financial waters.     

Evaluating a Measure of ‘Social Orientation’ of Chinese Students in Social Work: Developing its Reliability and Validity

This study examines the reliability and validity of a measure of ‘social orientation’ indigenously developed from Chinese students of social work in Hong Kong. By administering two tests with Chinese social work students (n = 293 and n = 304) at associate degree level, the measure achieves strong internal consistency with r>0.75 and test–retest consistency with r>0.63. The instrument also has strong validity by attempting factor analysis of items generated from qualitative data in in‐depth interviews. The development of this indigenous measure of ‘social orientation’ will contribute to an understanding of the authoritarian, relationship and ‘other’ orientation of Chinese social work students. The authors propose that this will be a crucial factor in influencing the response of Chinese students towards different teaching and learning approaches in social work education.     

Relationship satisfaction and sexual satisfaction: A longitudinal study of individuals in long‐term relationships

This study examined the association between relationship satisfaction and sexual satisfaction over time to provide evidence about possible causal explanations for the association between the two variables. Eighty‐seven individuals in long‐term relationships completed measures of sexual satisfaction and relationship satisfaction at 2 times 18 months apart. There was only limited evidence, based on exploratory analyses, to support either the hypothesis that changes in relationship satisfaction lead to changes in sexual satisfaction or the hypothesis that changes in sexual satisfaction lead to changes in relationship satisfaction. However, sexual satisfaction and relationship satisfaction were found to change concurrently. The quality of intimate communication accounted for part of the concurrent changes in relationship satisfaction and sexual satisfaction. I discuss the results in terms of the need to develop more complex models depicting the longitudinal associations between relationship satisfaction and sexual satisfaction.
