Critical analysis of blogging in public relations

This essay conducts an analysis of blogs as public relations tools. Following an overview of blogs, attention is given to how blogs can be used more effectively by public relations professionals, and how blogs are favored by communication firms and consultants as essential public relations tools. The essay concludes that while blogs have incredible potential as research, framing, and persuasion tools, their utility as a public relations tool is currently limited.     

Family Therapy with the Elderly

This article outlines health and lifestyle challenges to elderly persons and associated changes in their family systems. Flexibility, related to attachment patterns, is considered central to healthy adaptation. Family therapy approaches and relevant systemic and cultural factors influencing psychotherapy with the elderly are discussed. Key family therapy concepts and strategies (genograms, transmission of family histories and circular patterns of interaction), are reviewed and exemplified. Four types of family therapy presentations are elucidated by composite case examples. Firstly, the elderly person can be the identified patient. Secondly, another family member can seek help for him/herself in relation to the elderly person. Thirdly, another family member can be the identified patient without direct reference to the elderly person. Finally, the wider health care system involved with the elderly person and family can be the focus of therapy. Family therapy offers important conceptual and strategic advantages in working with the elderly and their systems.     

An Interagency Comparison of Screening-Level Risk Assessment Approaches

Approaches to risk assessment have been shown to vary among regulatory agencies and across jurisdictional boundaries according to the different assumptions and justifications used. Approaches to screening-level risk assessment from six international agencies were applied to an urban case study focusing on benzo[a]pyrene (B[a]P) exposure and compared in order to provide insight into the differences between agency methods, assumptions, and justifications. Exposure estimates ranged four-fold, with most of the dose stemming from exposure to animal products (8-73%) and plant products (24-88%). Total cancer risk across agencies varied by two orders of magnitude, with exposure to air and plant and animal products contributing most to total cancer risk, while the air contribution showed the greatest variability (1-99%). Variability in cancer risk of 100-fold was attributed to choices of toxicological reference values (TRVs), either based on a combination of epidemiological and animal data, or on animal data. The contribution and importance of the urban exposure pathway for cancer risk varied according to the TRV and, ultimately, according to differences in risk assessment assumptions and guidance. While all agency risk assessment methods are predicated on science, the study results suggest that the largest impact on the differential assessment of risk by international agencies comes from policy and judgment, rather than science.     

New Trends in Measuring Environmental Attitudes: Measuring Endorsement of the New Ecological Paradigm: A Revised NEP Scale

Dunlap and Van Liere's New Environmental Paradigm (NEP) Scale, published in 1978, has become a widely used measure of proenvironmental orientation. This article develops a revised NEP Scale designed to improve upon the original one in several respects: (1) It taps a wider range of facets of an ecological worldview, (2) It offers a balanced set of pro- and anti-NEP items, and (3) It avoids outmoded terminology. The new scale, termed the New Ecological Paradigm Scale, consists of 15 items. Results of a 1990 Washington State survey suggest that the items can be treated as an internally consistent summated ratingscale and also indicate a modest growth in pro-NEP responses among Washington residents over the 14 years since the original study.     

Taxonomy of mediated crisis responses

This paper examines how organizations integrate the Internet into crisis communication. The findings of a 7-year longitudinal study provide a taxonomy explaining how mediated communication creates new possibilities for crisis response. We translate the study findings into suggestions for how public relations managers can integrate new communication media into their mix of communication tactics in crisis and risk management.

Model fitting and inference under latent equilibrium processes

This paper presents a methodology for model fitting and inference in the context of Bayesian models of the type f(Y | X,θ)f(X|θ)f(θ), where Y is the (set of) observed data, θ is a set of model parameters and X is an unobserved (latent) stationary stochastic process induced by the first order transition model f(X ^(t+1)|X ^(t),θ), where X ^(t) denotes the state of the process at time (or generation) t. The crucial feature of the above type of model is that, given θ, the transition model f(X ^(t+1)|X ^(t),θ) is known but the distribution of the stochastic process in equilibrium, that is f(X|θ), is, except in very special cases, intractable, hence unknown. A further point to note is that the data Y has been assumed to be observed when the underlying process is in equilibrium. In other words, the data is not collected dynamically over time. We refer to such specification as a latent equilibrium process (LEP) model. It is motivated by problems in population genetics (though other applications are discussed), where it is of interest to learn about parameters such as mutation and migration rates and population sizes, given a sample of allele frequencies at one or more loci. In such problems it is natural to assume that the distribution of the observed allele frequencies depends on the true (unobserved) population allele frequencies, whereas the distribution of the true allele frequencies is only indirectly specified through a transition model. As a hierarchical specification, it is natural to fit the LEP within a Bayesian framework. Fitting such models is usually done via Markov chain Monte Carlo (MCMC). However, we demonstrate that, in the case of LEP models, implementation of MCMC is far from straightforward. The main contribution of this paper is to provide a methodology to implement MCMC for LEP models. We demonstrate our approach in population genetics problems with both simulated and real data sets. The resultant model fitting is computationally intensive and thus, we also discuss parallel implementation of the procedure in special cases.     

Film Portrayals of Social Workers Doing Child Welfare Work

This article reports on research that investigated the images of social workers engaged in child welfare work as portrayed in movies, a major medium of popular culture. Findings from an analysis of 27 movies spanning from 1938 to 1999 are presented with particular attention to themes about how children are depicted as recipients of child welfare services and how child welfare worker activities and interventions are portrayed. Ways that the results of the research can guide intervention efforts that more accurately and more completely portray the activities, values, and knowledge base of the profession of social work are suggested.
