Researchers have proposed that work-family policy use may either reinforce or challenge the existing gendered division of
labor within couples, but results from prior studies have been inconclusive. Using data from a regional survey of work and
family life, we extend this research by focusing on how housework is divided within couples and by differentiating between
traditionally female- and male- typed housework tasks. Results show that among dual-earning women, policy use is not related to share of female- or male-typed
tasks. Among dual-earning men, policy use is positively related to share of female-typed tasks and negatively related to share
of male-typed tasks. These findings suggest that work-family policy use does not reinforce the gendered division of housework.

Communities across the nation have become increasingly concerned about inhalant use and use of harmful legal products among youth because of increasing prevalence rates and deleterious health consequences from abusing these products. The increasing concern of communities about inhaling and ingesting legal products has been coupled with increasing awareness and concern about ability of youth to access and abuse a variety of other legal retail products. There are few examples of scientifically designed community prevention projects that seek to reduce youth abuse of such legal products. This article describes a community prevention trial that is designed to reduce sales of inhalants and other harmful legal products to youth and demonstrates how the retailer component of the trial can be rigorously evaluated. It also shows how data from youth purchase attempts can complement survey data from retailers. 相似文献

江南名山是中国名山文化的重要组成部分,其形象的开发和利用为古代文人和知识分子所主导,是当前完善名山风景建设的关键因素,而诗词文本则是江南名山形象构建的见证。本文以江南名山茅山为研究案例,结合元代刘大彬所著《茅山志·金薤篇》中记载的茅山相关诗词及网络搜集的补充诗词为文本材料,运用扎根理论对文本内容进行三级编码,归纳形成包括山地、生物、天象、气象资源等在内的十五个初始范畴和自然资源、文化特征、审美活动、行为互动、建筑设施五个主范畴,进而利用文本分析软件ROST CM6进行词频分析、社会网络与语义网络分析、情感意象分析。分析发现诗词文本中自然资源构成了茅山风景区核心景观资源。情感意象分析发现,中性情感比重最大,"归隐"频次最高,反映出诗人普遍以茅山寄托隐居志向,积极情感多表达诗人对自然资源的由衷喜爱。最后构建江南名山形象塑造过程的模型,认为永嘉之乱后江南名山得到了发展,优越的自然条件作为风景要素,是形象认知的起点和自然供给力。宗教文化的发展进一步推动了山岳诗文的创作,二者构成重要的文化供给力。隐居和游观活动的兴盛则是江南名山文化吸引力的重要体现。总结得出了茅山江南名山形象,为后续江南名山形象认知的研究打下基础。 相似文献

A knowledge-based system supporting managerial problem diagnosis is described. The system provides the capability to monitor values of selected variables for problem situations. When problems are located, a list of problem symptoms is delivered to a problem processor for structuring and diagnosis. Problem structuring is based on a combination of concepts from expert systems and structural modeling. User assertions about cause-effect relationships between pairs of variables are maintained in a semantic network. Problem diagnosis uses the relationships in the semantic network to construct causation trees, the branches of which represent potential explanations of the problem symptoms. Mathematical models are constructed based on causation-tree branches, and values from the data base are used to test whether the model confirms the diagnosis. If so, the source of the problem has been located and it is then up to the user to resolve the problem. If the model fails to explain the problem, the model apparently is deficient and the user may perform “what if…” type scenarios in attempts to improve the model and search for problem causes. Realistic applications in the accounting and health care areas are discussed. 相似文献

Multiple-predictor empirical and single-predictor judgment-based models represent the two basic types of sales-force decision models (SDMs). The important similarities and differences between the two modeling approaches are identified and discussed. The SDM literature is reviewed to determine how each model type has been applied and to evaluate previous attempts at model validation. A research study designed to compare the normative sales-call allocations generated from each modeling approach is presented. Study results indicate that empirical and judgment-based SDMs would produce similar normative guidelines. The implications of this finding are discussed. 相似文献
