远视近视自动切换的眼镜

正现代人因为过度使用电子产品,近视人群越来越多,所以无论是框架眼镜还是隐形眼镜都很畅销。但畅销不代表能完全满足人们的视觉需求,比如近视的人看不清远处,远视的人看不清近处,这种情况会加速眼睛的疲劳度。那么,有没有一款黑科技眼镜让远视近视自动     

Critical Discourse,Applied Inquiry and Public Health Action with Urban Middle School Students: Lessons Learned Engaging Youth in Critical Service-Learning

The Nuestro Futuro Saludable partnership designed a critical service-learning intervention focused on health equity and action. The 10-week afterschool intervention was implemented in a Boston middle school. Youths who took part in the intervention were knowledgeable about the social determinants of health in their communities, as well as to the barriers to health. Our findings indicate that engaging young people in a meaningful way will be critical if health improvement efforts are to be realized. We found that a critical service-learning framework that incorporates elements of applied inquiry and critical pedagogy was effective as a health intervention and provided opportunities for action.     

A decision support system for banks

Just recently, information systems with rather unique characteristics have begun to emerge. These systems usually referred to as Decision Support Systems, feature decision models, a data base and the decision maker as subsystems and are specifically oriented to supporting decision making. This article examines Decision Support Systems and their application to banks.     

Getting your supervisors and managers on the right team

They do a great job. So we promote them. Now they supervise people who don't do the job as well as they did. We give them a big raise. But because they're exempt they make less than their leads. They have the toughest job in the company—managing people. So we grant them an entire day of training to prepare. We ask them to mentor, coach, and have close relationships with their direct reports—all 132 of them. Then when the stock dips, we blame “middle management” and lay a bunch of them off.     

The impact of child and parental age on protective factors against child maltreatment

Although young age for both the parent and child is implicated in incidences of maltreatment, little is known about the association between parent or child age and protective factors related to child maltreatment prevention. With a sample of parents receiving child maltreatment prevention services in Kansas ( N  = 1993), we used regression analyses to examine whether the interaction of child and parent age influences family‐level protective factors over time. We found mixed support for each hypothesis, indicating that the age of parents and children differentially impacts family‐level protective factors. Implications for the Strengthening Families approach and child maltreatment prevention are discussed.     

An Application of Bayesian Methods to Small Area Poverty Rate Estimates

Efforts to estimate various sociodemographic variables in small geographic areas are proving difficult with the replacement of the Census long-form with the American Community Survey (ACS). Researchers interested in subnational demographic processes have previously relied on Census 2000 long-form data products in order to answer research questions. ACS data products promise to begin providing up-to-date profiles of the nation’s population and economy; however, unit- and item-level nonresponse in the ACS have left researchers with gaps in subnational coverage resulting in unstable and unreliable estimates for basic demographic measures. Borrowing information from neighboring areas and across time with a spatiotemporal smoothing process based on Bayesian statistical methods, it is possible to generate more stable and accurate estimates of rates for geographic areas not represented in the ACS. This research evaluates this spatiotemporal smoothing process in its ability to derive estimates of poverty rates at the county level for the contiguous United States. These estimates are then compared to more traditional estimates produced by the US Census Bureau, and comparisons between the two methods of estimation are carried out to evaluate the practical application of this smoothing method. Our findings suggest that by using available data from the ACS only, we are able to recreate temporal and spatial patterns of poverty in US counties even in years where data are sparse. Results show that the Bayesian methodology strongly agrees with the estimates produced by the SAIPE program, even in years with little data. This methodology can be expanded to other demographic and socioeconomic data with ease.     

Male homosexuality in western culture: the dilemma of identity and subculture in historical research

This article examines recent historical literature dealing with concepts of homosexual identity and subculture. It focuses on the current historiographical debate between the essentialists and the social constructionists. Historians are searching for the origins of the modern homosexual and for ways to explain the unique development of homosexual identities and subcultures in western societies. The distinction is drawn between macroanalysis and microanalysis. After critically examining their efforts, the article suggests the need to avoid focusing on global historical forces, which might account for the emergence of a homosexual identity (macroanalysis), and, instead, to analyze carefully particular homosexual subcultures (microanalysis). This latter approach can provide insights into the variety of homosexual social roles and identities that have existed in history.
