Disease control efforts directed at human immunodeficiency virus are predicated on the need to reduce personal risk behaviors; that approach may not adequately reflect the complicated interplay between personal behaviors and the social setting in which they occur. Efforts to date, including the application of population ecology, the development of the core group hypothesis, and the use of compa...

OBJECTIVE To assess the effects of preventive home visits to elderly people living in the community. DESIGN Systematic review. SETTING 15 trials retrieved from Medline, Embase, and the Cochrane controlled trial register. MAIN OUTCOME MEASURES Physical function, psychosocial function, falls, admissions to institutions, and mortality. RESULTS Considerable differences in the methodological...

Article history: Received 9 November 2012 Received in revised form 27 June 2013 Accepted 28 August 2013 Available online 27 November 2013 This study focuses on the appropriation process of two public computing infrastructures in the City of Oulu, Finland, a municipalWiFi network and large interactive displays. We analyze the adoption of these technologies in public urban places with a conceptua...

In thermal characterization tests of bone cement according to the ASTM Standard Specification for Acrylic Bone Cement, time-temperature profiles of bone cement were observed to be sensitive to the thickness of the cement patty and the mold material. Due to the heat transfer from cement to the surrounding mold, such tests might underestimate the exothermic temperature of bone cement. Developing ...

In this paper, we compare two alternative design strategies for the Delta Design Game, an engineering design exercise. We first analyze these strategies using the Work Transformation Matrix, a design iteration model which shows that one of the strategies is expected to display a faster solution time. We then demonstrate experimentally the difference in development time by observing eight design...

Acknowledgements First of all, I want to thank my advisor – Dr. Starzyk, who recognized that the PicoBlaze microcontroller core is adaptable to neural network application at the very early stage after PicoBlaze was developed. And before then, I had been working on the SOLAR implementation using a kind of serial based processing in the hardware. This new design component (PicoBlaze) gave me much...

Many Western countries face the challenge of reconciling future labor demand with growing public opposition to immigration. The dynamics and underlying processes of setting immigration requirements remain unclear as research so far mainly focuses on context-specific empirical studies. We use a public good game experiment with endogenous groups to investigate how different levels of perceived mi...

in the course of this study, empirical models were developed for the pressure-density relationship in a large cubic baler for baling alfalfa and barley straw. least squares regression analysis was employed to develop the empirical model and estimate the model coefficients by minimizing the summation of the squared differences between data resulting from the developed empirical model and the cor...
