Demographic, health, cognitive, and sensory variables as predictors of mortality in very old adults

Cognitive and sensorimotor predictors of mortality were examined in the Australian Longitudinal Study of Ageing, controlling for demographic and health variables. A stratified random sample of 1,947 males and females aged 70 and older were interviewed, and 1,500 were assessed on measures of health, memory. verbal ability, processing speed, vision, hearing, and grip strength in 1992 and 1994. Analyses of incident rate ratios for mortality over 4- and 6-year periods were conducted using Cox hierarchical regression analyses. Results showed that poor performance on nearly all cognitive variables was associated with mortality, but many of these effects were explained by measures of self-rated health and disease. Significant decline in hearing and cognitive performance also predicted mortality as did incomplete data at Wave 1. Results suggest that poor cognitive performance and cognitive decline in very old adults reflect both biological aging and disease processes.     

An Introduction to Kristof’s Theorem for Solving Least-Square Optimization Problems Without Calculus

Kristof’s Theorem (Kristof, 1970 Kristof, W. (1970). A theorem on the trace of certain matrix products and some applications. Journal of Mathematical Psychology, 7(3), 515–530. https://doi.org/10.1016/0022-2496(70)90037-4[Crossref], [Web of Science ®] , [Google Scholar]) describes a matrix trace inequality that can be used to solve a wide-class of least-square optimization problems without calculus. Considering its generality, it is surprising that Kristof’s Theorem is rarely used in statistics and psychometric applications. The underutilization of this method likely stems, in part, from the mathematical complexity of Kristof’s (1964 Kristof, W. (1964). Die beste orthogonale Transformation zur gegenseitigen Uberfiihrung zweier Faktorenmatrizen. Diagnostica, 10, 87–90. [Google Scholar], 1970 Kristof, W. (1970). A theorem on the trace of certain matrix products and some applications. Journal of Mathematical Psychology, 7(3), 515–530. https://doi.org/10.1016/0022-2496(70)90037-4[Crossref], [Web of Science ®] , [Google Scholar]) writings. In this article, I describe the underlying logic of Kristof’s Theorem in simple terms by reviewing four key mathematical ideas that are used in the theorem’s proof. I then show how Kristof’s Theorem can be used to provide novel derivations to two cognate models from statistics and psychometrics.

Landmarks as beacons and associative cues: Their role in route learning

Relatively little is known about how people use the landmarks in their environment to learn routes. Landmarks are commonly regarded as associative cues--stimuli that enable recall of directional responses that lead closer to the navigator's goal. We contrast the function of landmark as associative cue with that of a beacon-a landmark near enough to a goal that moving toward it leads the navigator closer to his or her goal. In five experiments, participants learned a route through a simple desktop virtual environment. In the first three experiments, routes were learned better when their landmarks served as beacons than as associative cues. Two additional experiments showed that the acquired route knowledge depends on the function that landmarks serve during learning. Beacon-based route knowledge is less enduring and relatively less likely to involve knowledge of directions in the environment than is the route knowledge formed from landmarks that serve as associative cues.     

The Psychology of News Influence and the Development of Media Framing Analysis

How precisely do media influence their readers, listeners and viewers? In this paper, we argue that any serious study of the psychology of media influence must incorporate a systematic analysis of media material. However, psychology presently lacks a methodology for doing this that is sensitive to context, relying on generalised methods like content or discourse analysis. In this paper, we develop an argument to support our development of a technique that we have called Media Framing Analysis (MFA), a formal procedure for conducting analyses of (primarily news) media texts. MFA draws on elements of existing framing research from communication and other social scientific research while at the same time incorporating features of particular relevance to psychology, such as narrative and characterisation.     

The marketing of industrial real estate: application of Taguchi loss functions

The marketing of industrial real estate is a resource‐consuming endeavour for all parties involved consisting of many objectives that, in many cases, may be in conflict with one another. One method of minimizing resource requirements, especially time, while increasing the probability of a successful match is to select properties for presentation that maximizes buyer utility. Zionts (1992) indicated one area for future research in multiple criteria decision‐making (MCDM) is in the development of ‘Eclectic Approaches’ using old ideas in a new way to help develop MCDM approaches. In this paper Taguchi loss functions, a procedure commonly used in quality control, is proposed as a tool that can be used by industrial real estate professionals to more efficiently determine the property that most closely matches the buyer's needs.

Validity of a Brief Measure of Parental Affective Attitudes in High-Risk Preschoolers

The current study investigated psychometric properties of the Family Affective Attitude Rating Scale (FAARS) for assessing parents' thoughts and feelings about their child, coded from a 5-min speech sample. Parental affective attitudes derive from previous experiences of parenting and child behavior, representations of the parent-child relationship and broader parental characteristics. Data were collected from mother-child dyads at ages 2 and 3 (N?=?731; 49?% female) from a multi-ethnic and high-risk community sample. Multi-informant observations of parenting and questionnaire measures were used to test construct and discriminant validity. FAARS showed good internal consistency and high inter-rater agreement. Affective attitudes were related to mothers' perceptions of their daily hassles, their reports of conflict with their child, and observed measures of positive and harsh parenting. Negative affective attitudes uniquely predicted later child problem behavior, over and above maternal reports of and observed measures of parenting. Overall, results support the validity of FAARS coding in mothers of preschoolers, a previously untested group. FAARS is a novel measure, directly assessing maternal perceptions of the parent-child relationship, and indirectly providing an index of maternal affect, stress, and depressive symptoms. Its brevity and cost-effectiveness further enhance the potential use of the FAARS measure for clinical and research settings.     

Ethnic Identity Gratifications Selection and Avoidance by African Americans: A Group Vitality and Social Identity Gratifications Perspective

Abstract

This study explores the relatively new idea that individuals engage with media in an effort to meet their social identity needs. Specifically, the study broadens the social identity gratifications (SIG) approach to the domain of ethnicity by examining how African Americans’ ethnic identity gratifications selection and avoidance are related to their perceptions of ingroup vitality. Two mediation models involving level of ethnic identification are proposed. Although the model of television selection is not supported, the model of television avoidance is supported. Implications and future research are discussed.     

Twelve steps to heaven: Successfully managing change through developing innovative teams

In this article we propose that work teams implement many of the innovative changes required to enable organizations to respond appropriately to the external environment. We describe how, using an input?–?process?–?output model, we can identify the key elements necessary for developing team innovation. We propose that it is the implementation of ideas rather than their development that is crucial for enabling organizational change. Drawing on theory and relevant research, 12 steps to developing innovative teams are described covering key aspects of the team task, team composition, organizational context, and team processes.
