Little information is available on product use by consumers, which severely hampers exposure estimation for consumer products. This article describes actual contact with several consumer products, specifically dishwashing detergents, cleaning products, and hair styling products. How and where products are handled, as well as the duration, frequency, and amount of use were studied by means of diaries, in‐home observations, and measurements. This study addressed the question, “To what extent are frequency, duration, and amount of use associated?” Findings showed that there was a large intra‐ as well as interindividual variation in frequency, duration, and amount of use, with the interindividual variation being considerably larger. At the same time, results showed that, for a given activity, users tended to follow their own routine. Few relations were found among frequency, duration, and amount of use. It was concluded that among persons, frequency, duration, and amount of product act in practice as independent parameters. Diaries appear to be quite suitable for gaining insight into frequently used products. Observations of usage, recorded on video, were indispensable for obtaining particular information on product use. In addition, home visits enabled the collection of specific measurements. Although diaries and home visits are time‐consuming, the combination provided insight into variation as well as relations among frequency, duration, and amount of use. 相似文献

With the aim of identifying the age of onset of change in the rate of cognitive decline while accounting for the missing observations, we considered a selection modelling framework. A random change point model was fitted to data from a population-based longitudinal study of ageing (the Cambridge City over 75 Cohort Study) to model the longitudinal process. A missing at random mechanism was modelled using logistic regression. Random effects such as initial cognitive status, rate of decline before and after the change point, and the age of onset of change in rate of decline were estimated after adjustment for risk factors for cognitive decline. Among other possible predictors, the last observed cognitive score was used to adjust the probability of death and dropout. Individuals who experienced less variability in their cognitive scores experienced a change in their rate of decline at older ages than individuals whose cognitive scores varied more. 相似文献

We connect the recent medical and economic literatures on the long-run effects of early-life conditions by analyzing the effects
of economic conditions on the individual cardiovascular (CV) mortality rate later in life, using individual data records from
the Danish Twin Registry covering births since the 1870s and including the cause of death. To capture exogenous variation
of conditions early in life, we use the state of the business cycle around birth. We find significant negative effects of
economic conditions around birth on the individual CV mortality rate at higher ages. There is no effect on the cancer-specific
mortality rate. From variation within and between monozygotic and dizygotic twin pairs born under different conditions, we
conclude that the fate of an individual is more strongly determined by genetic and household-environmental factors if early-life
conditions are poor. Individual-specific qualities come more to fruition if the starting position in life is better. 相似文献

Stratification research has extensively studied country-differences in the strength of the relationship between education and labor market outcomes. This research has mostly neglected the different mechanisms that could explain why education is rewarded. In this paper we argue that not only the strength of the relationship, but also the mechanisms explaining why education is rewarded differ between countries. National institutions affect how employers see education, what it brings to the organization, and how workers signal their potential productivity. Empirically we focus on the partial effects of qualifications on top of years of education in 15 European countries. We find that strongly vocationally oriented and differentiated schooling systems have relatively strong net effects of qualifications on occupational status, which is explained by stronger signalling by qualification levels in those countries. Furthermore, in coordinated market economies we find that vocational education leads to higher status jobs relative to liberal market economies, which is explained by higher levels of closure implemented by coordination institutions. 相似文献

The Vietnamese government aims to expand the scale of Naturland certified organic production in integrated shrimp–mangrove farming systems across the coast of Ca Mau province by 2015. In doing so the division between public and private regulation has become blurred. We analyze the government's goal by examining the regulatory challenges of using organic certification as a means of linking farm-level management to the sustainability of coastal (mangrove) landscapes. The results show the importance of farmer perceptions of sustainable farm and landscape management, fair benefit sharing mechanisms in the certified value chain, and legitimate private sector-led auditing. We conclude that in order to overcome conflicts of interest and legitimate representation in organic certification, the social and economic conditions of production require regulatory intervention from provincial and local level government. To achieve benefits beyond the scale of the farm, the role of shrimp producers should be redefined as partners in rather than targets of regulation. 相似文献

In western welfare states, labour participation is increasingly considered a vital aspect of taking part in society. Vocational rehabilitation programmes are intended to support people in the process of returning to work. These programmes pay much attention to the skills that clients need to develop in order to return to work. We argue, however, that vocational rehabilitation is more than the acquirement of skills, and that further attention should be paid to clients’ ‘identity work’ processes. Based on 45 life-stories, we present an analysis of the identity work expressed by people with a work disability in the Netherlands. We describe ‘separative’, ‘integrative’, and ‘pending’ processes of identity work. The presented typology can help vocational rehabilitation professionals become more sensitive to clients’ processes, and supports more inclusive vocational rehabilitation. 相似文献

Through Brazilian publication revision on the relations amongst Ergonomics and Design, we observed the tendency towards an approach focusing on product design. However, it is our duty to question which would be the influences of ergonomics in the graphic design. As a methodology, we considered the identification that the practices derived from ergonomics as epistemic system found in the main bibliography related to graphic design. 相似文献

This paper focuses Design importance in the development of effectively inclusive products based on Design Emotional approach, allowing children with disabilities to experience playing in the childhood as an instrument for social integration. The methodology used to develop this study was based on literature review, considering the following themes: emotional design, accessibility and inclusion, emotion and development of children. As a result, we propose a new level of need to model the hierarchy of needs, of Jordan ("usability", "functionality" and "pleasure"), level with the inclusion of "dignity." 相似文献

This study analyzes Eritrean refugee women's utilization of antenatal services in Israel by means of retrospective self‐reports surveys (N = 63) targeting women's service utilization (array of services used, frequency rates, facility rates and demographic correlates) and semi‐structured interviews (N = 10) targeting women's experienced barriers for service utilization. Findings show that Eritrean women make substantive use of the full array of services, with user rates increasing over time. However, frequency rates are low, although increasing when women have more experience with the system. Facility rates are not in keeping with the recommendations of the Israeli Ministry of Health. Interviews reveal that the barriers of work and a complex system of antenatal care limit women's frequent service utilization in the right facility, while the barrier of miscommunication limits their understanding of the services they actually utilized. Findings stress the importance of analyzing different facets of utilization and their demographic correlates. 相似文献
