Graphs in Scientific Publications

Graphical communication in scientific publications can be improved; a detailed analysis of all graphs in one volume of Science revealed that 30% had errors. Graphs are used more in some disciplines than in others; a survey of 57 journals revealed natural science journals use far more graphs than mathematical or social science journals. Usage studies such as these provide important information for developing four other areas: new graphical methods for data presentation, guidelines, software, and human graphical perception.     

Norm-preserving constraint in the Fisher–Rao registration and its application in signal estimation

Registration of temporal observations is a fundamental problem in functional data analysis. Various frameworks have been developed over the past two decades where registrations are conducted based on optimal time warping between functions. Comparison of functions solely based on time warping, however, may have limited application, in particular when certain constraints are desired in the registration. In this paper, we study registration with norm-preserving constraint. A closely related problem is on signal estimation, where the goal is to estimate the ground-truth template given random observations with both compositional and additive noises. We propose to adopt the Fisher–Rao framework to compute the underlying template, and mathematically prove that such framework leads to a consistent estimator. We then illustrate the constrained Fisher–Rao registration using simulations as well as two real data sets. It is found that the constrained method is robust with respect to additive noise and has superior alignment and classification performance to conventional, unconstrained registration methods.     

FAMILY SYSTEMS THERAPY IN A PRIMARY CARE MEDICAL SETTING: THE ROCHESTER EXPERIENCE

Collaboration between family therapists and physicians has attracted increasing attention in the field of family therapy. Family therapists practicing in medical settings encounter many stimulating oppoutunities and challenges. This paper focuses on the experience of the authors providing family therapy in a primary care medical setting which is also a family medicine residency program. The authors discuss the role of physician and patient expectations in treatment as well as the influence of the medical context on the development of family therpists.     

Cognitive Style and its Relevance for Management Practice

This review paper addresses some of the semantic issues associated with the nature of cognitive style, identifies some of the most often cited dimensions of cognitive style, examines ways in which these styles can be classified and considers the implications of cognitive style for management practice.     

Neighborhood influences on physical activity in middle-aged and older adults: a multilevel perspective

Over the past few years, attention has been drawn to the importance of neighborhood influences on physical activity behavior and the need to consider a multilevel analysis involving not only individual-level variables but also social- and physical-environment variables at the neighborhood level in explaining individual differences in physical activity outcomes. This new paradigm raises a series of issues concerning systems of influence observed at different hierarchical levels (e.g., individuals, neighborhoods) and variables that can be defined at each level. This article reviews research literature and discusses substantive, operational, and statistical issues in studies involving multilevel influences on middle-aged and older adults' physical activity. To encourage multilevel research, the authors propose a model that focuses attention on multiple levels of influence and the interaction among variables characterizing individuals, among variables characterizing neighborhoods, and across both levels. They conclude that a multilevel perspective is needed to increase understanding of the multiple influences on physical activity.
