Time use studies find that employed mothers reduce their parental childcare time by much less than an hour for every hour
they spend in market work. This paper uses data from the Australian Bureau of Statistics Time Use Survey 1997 (4,059 randomly selected households) to investigate how employed mothers manage to avoid a one-for-one trade-off between
work and childcare. It compares the time allocation of employed fathers, employed mothers and non-employed mothers and finds
that parents use non-parental childcare to reschedule as well as to replace their own childcare, that employed mothers reschedule
activities from weekdays to weekends or to earlier or later in the day, and spend less time than other mothers in housework,
childfree leisure and personal care.

Assessing the effects of land use and land cover patterns on thermal conditions using landscape metrics in city of Indianapolis,United States 总被引:6,自引:0,他引:6
Direct applications of remote sensing thermal infrared (TIR) data in landscape ecological research are rare due to limitations
in the sensors, calibration, and difficulty in interpretation. Currently there is a general lack of methodology for examining
the relationship between land surface temperatures (LST) derived from TIR data and landscape patterns extracted from optical
sensors. A separation of landscapes into values directly related to their scale and signature is a key step. In this study,
a Landsat ETM+ image of Indianapolis, Unites States, acquired on June 22, 2000, was spectrally unmixed (using spectral mixture
analysis, SMA) into fraction endmembers of green vegetation, soil, high albedo, and low albedo. Impervious surface was then
computed from the high and low albedo images. A hybrid classification procedure was developed to classify the fraction images
into seven land use and land cover (LULC) classes. Using the fractional images, the landscape composition and pattern were
examined. Next, pixel-based LST measurements were correlated with the landscape fractional components to investigate LULC
based relationships between LST and impervious surface and green vegetation fractions. An examination of the relationship
between the LULC and LST maps with landscape metrics was finally conducted to deepen understanding of their interactions.
Results indicate that SMA-derived fraction images were effective for quantifying the urban morphology and for providing reliable
measurements of biophysical variables. LST was found to be positively correlated with impervious surface fraction but negatively
correlated with green vegetation fraction. Each temperature zone was associated with a dominant LULC category. Further research
should be directed to the theoretical and applied implications of describing such relationships between LULC patterns and
urban thermal conditions.

This study examines the association between individuals' educational assortative mating and time spent on child care and housework. Focus is put on hypogamous couples, or couples in which wives have more education than their husbands. Relative resources and gender revolution frameworks are considered as contexts to explain why hypogamous couples may share their time differently than other couples. A series of ordinary least squares regressions with population and sampling weights are employed using American Time Use Survey data from 2003 to 2018. Three, separate analyses using relative education, gender, and all educational pairings as the independent variables of interest are presented with child care and housework as the dependent variables. The current findings show that men in hypogamous marriages perform about 10 min more of child care per day on average than their peers in hypergamous and homogamous marriages, and that this comes primarily from basic care activities. This accounts for approximately 43% of the difference between men and women in the average amount of time spent on child care. No clear pattern of significance is apparent comparing individuals’ time spent on housework by relative education, suggesting that housework and child care have evolved differently in the context of gendered domestic responsibilities. Men in hypogamous marriages are more egalitarian in their sharing of child care. However, this is only true for couples in which men have at least a high school diploma and women are highly educated. 相似文献

Do people think individuals with Substance Use Disorder (SUD) have freewill? How does addiction science inform views on the issue? We distinguish between two senses of freewill: 1) libertarian freewill , in which freedom turns on a particular metaphysical conception of action (sometimes operationalized as “could have done otherwise”), and 2) compatibilist freewill , in which freedom depends on the relation between the actor's psychology and her actions (e.g., “was the act what she wanted to do?”). We argue that, in different ways, scientific accounts can impact conceived freewill by linking addictive behavior to mechanisms that observers view as peripheral to the actor ( motivation modularity) . While a variety of impacts on conceived compatibilist freewill are plausible, we argue that contemporary addiction science has no direct bearing on conceived libertarian freewill. Addiction science may, however, indirectly impact conceived libertarian freewill by priming an explanatory framework in which intention is superfluous (especially materialism). 相似文献

The E-Learning Outreach Program (ELOP) is a multisectoral, collaborative, and commitment-driven action research that focuses on providing relevant and useful computer and Internet literacy short courses for public elementary students. This study presents the critical action plans of setting up a pilot e-Learning station in Hen. Pio del Pilar Elementary School in Makati City and in Pulo Elementary School in Cabuyao City, Laguna, Philippines. The school’s computer laboratory was converted to an E-Learning station with additional devices and technical support from De La Salle University (DLSU). The study aims to account for a process-based heuristic approach in laying down the different phases of the program, specifically to: (1) coordinate and orient parents, pupils, teachers and school administrators, (2) set-up an e-Learning environment (3) design and write course modules (4) assess learning skills and experience of pupils, and (5) evaluate the program based on research team’s observation and results of the focus group discussion (FGD) with teachers and student-participants. In Pulo Elementary School, a pretest and posttests were conducted with results showing that the program has improved participants’ e-Learning knowledge and skills except for advance skills in hardware utilization. The participants also showed a strong positive attitude towards the ELOP. 相似文献

ABSTRACT The aim of this study was to explore the effectiveness of Methadone Maintenance Treatment (MMT) from the perspective of drug users and their families. For this qualitative content analysis study, 15 participants were selected via purposive sampling. Data collection was done using deep and semi-structured interviews, which were then analyzed. The results showed that MMT can bring favorable impacts into the patients’ lives and help them with the process of treatment and rehabilitation despite the medical side effects. 相似文献

两周金文共有的第二人称代词有"女"、"乃"、"尔",它们的语法功能一直比较稳定。"余、朕、女、乃"和"我、尔"在殷商以前可能属于不同方言,后者之进入前者所在方言,可能就是为了补前者不表复数之不足。第二人称代词在殷商西周时可通用于各种身份的人之间,到东周春秋时期逐渐有了限制。从殷商西周到春秋战国,随着称谓礼仪的发展,称谓系统也发展得愈益丰富完善。 相似文献

Multisite evaluation has been cited as a strategy for building knowledge about a program's success and enhancing evaluation capacity and evaluation use. Even so, the extent to which data from these efforts are made available to individual project participants varies. This article describes a community-created multisite evaluation that was designed to overcome this limitation. Based on the negotiated centralized evaluation model and implemented within the context of a community of practice, the EvalFest community-created multisite evaluation has used shared measures to collect data from 30,000 participants from partner sites across the community over three years. This article describes the design characteristics of the community-created multisite approach, and presents results related to partners’ evaluation use that demonstrate the early success of this method. We conclude by considering how this strategy might be applied to other sectors. 相似文献

Objective: The objective of this study was to understand substance use patterns of alcohol, marijuana, and simultaneous alcohol and marijuana (SAM) use among 2- and 4-year college students. Participants: Participants were 526 young adults aged 18–23 (n?=?355 4-year students; n?=?171 2-year students) recruited from February 2015 to January 2016 who were participating in a larger longitudinal study. Methods: Latent class analysis (LCA) was used to identify past-month classes of alcohol, marijuana, and SAM use. Results: Among both 2- and 4-year students, a four-class solution yielded the best-fitting model, with 2-year classes tending to include greater marijuana use and less alcohol use and 4-year classes tending to include heavy alcohol use. Demographic characteristics were largely similar across classes. Conclusions: Classes of alcohol, marijuana, and SAM use differed by education status. Screening and prevention efforts for 4-year students may need to be tailored for the needs of 2-year students. 相似文献

Objective: Despite declining cigarette smoking rates in the US, there is a continued need for tobacco prevention education campaigns to reach young adults. Recognizing the need for improved tobacco control messaging, the University of Texas (UT) System engaged The University of Texas at Austin Center for Health Communication to develop a brand and message that would strengthen tobacco control efforts at its 14 institutions. Methods: This article describes the iterative process involved in creating a brand for tobacco control, including an environmental scan, identifying potential message themes, and creating and refining logos. Results: This article highlights the process of developing a system-wide tobacco control brand. Specifically, the process included coordinating an interdisciplinary team with content and design experts, and presenting ideas to stakeholders for serial feedback and refinement, among others. Conclusions: Ultimately, this project offers a model for other systems of higher education interested in pursuing similar initiatives. 相似文献
