A robot exploring an unknown environmentmay need to build a world model from sensor measurements. In order to integrate all the frames of sensor data, it is essential to align the data properly. An incremental approach has been typically used in the past, in which each local frame of data

call statecharts, extend conventional state-transition diagrams with essentially three olements, dealing, respectively, with the notions of hierarchy, concurrency and communication. These transform the language of state diagrams into a highly structured' and economical description language

. Control dependence5 are introduced to analogously represent only the essential control flow relationships of a program. Control dependences are derived from the usual control flow graph. Many traditional optimizations operate more efficiently on the PDG. Since dependences in the PDG connect

Many prominent theorists have argued that accurate perceptions of the self, the world, and the future are essential for mental health. Yet considerable research evidence suggests that overly positive selfevaluations, exaggerated perceptions of control or mastery, and unrealistic optimism

Abstract. Web users ’ concerns about their privacy result in reduction of online shopping activity. Widely spread Web marketing is not possible without an appropriate protection of customers ’ privacy. The significance of privacy in electronic commerce is illustrated in this article. We present a classification of Web privacy risks and describe an evolution of privacy enhancing technologies. It includes a review of Client-side Utilities, new protocol – P3P, simple Third Party Proxy Servers and more sophisticated Chaining with Encryption technique. The possibilities of mentioned solutions and their disadvantages are specified. Effective solutions are characterized by low performance and high costs of their realization. Electronic society’s unrealized demands are highlighted against this background. Our proposal of a new method of providing versatile anonymity for Web users is included in the summary of this discussion. The solution overcomes mentioned weaknesses. 1

Our research in statistical cognition uses both qualitative and quantitative methods. A mixed method approach makes our research more comprehensive, and provides us with new directions, unexpected insights, and alternative explanations for previously established concepts. In this paper, we review four statistical cognition studies that used mixed methods and explain the contributions of both the quantitative and qualitative components. The four studies investigated concern statistical reporting practices in medical journals, an intervention aimed at improving psychologists’ interpretations of statistical tests, the extent to which interpretations improve when results are presented with confidence intervals (CIs) rather than p-values, and graduate students ’ misconceptions about CIs. Finally, we discuss the concept of scientific rigour and outline guidelines for maintaining rigour that should apply equally to qualitative and quantitative research.

As such, life is arranged hierarchically with a foundation of discrete, unblendable units (codons, and, for the most part, genes) capable of combining to create increasingly complex and virtually limitless

Given the increasing complexity of our public health and health care systems, the public health profession has a more important role to play than ever in helping consumers / patients achieve and maintain optimal health. At the population level, public health professionals are at the forefront of research and education, forging multi-disciplinary alliances as never before. As a result, graduate degrees in public health are proliferating nationally. The need for health education in community and clinical health environments is great, and growing. This includes education about personal and community health issues; strategies to reduce risk and improve health; specific resources and tools to help consumers to take appropriate pro-health actions; and support systems (access, financial assistance, health information resources, etc.) to sustain such actions. The goals of health education are two-fold: to provide information to enhance consumer or patient knowledge; and to help effect positive and long-term change in health behaviors. This article provides a brief background of health education and health promotion, including an overview of its leading professional organization, the Society for Public Health Education (SOPHE); and explores the unique and critical role of the health educator in helping individuals internalize positive behavior-change, the ultimate goal of public health education. Health education was first defined in the 1940s as “...requiring careful and thorough consideration of present knowledge, attitudes, goals, perceptions, social status, power structure, cultural traditions, and other aspects of whatever public is to be addressed.”1
