Toward a pragmatic program for critical urban ecology

Our essay responds to the critique of Dooling et al. (Urban Ecosystems in press, 2007) of our previously published article “Goal attainment in urban ecology research: a bibliometric review 1975-2004 (Young and Wolf, Urban Ecosystems, 9:179–193, 2006). We identify our critics’ concerns as rooted in a project of deconstruction of scientific inquiry and a redefinition of the boundaries separating academic disciplines from each other and science from society. While we identify important differences with our critics, we largely support this critical project, as evidenced by our previously published empirical research. In exploring the relationship between critical and positivist approaches to urban ecology research and how we might work toward an integration of nature and society in thought and action, we defend pragmatic approaches to empirical research as well as disciplinary projects as legitimate and essential elements of urban ecology research. We argue in favor of theoretical and methodological pluralism. Rather than define urban ecology through exclusionary projects that would limit the scope and significance of urban ecology research, we reaffirm our call for diverse sets of actors inside and outside university settings to engage and support each other in order to develop and strengthen analysis and pursuit of sustainability.

The development and validation of The Inquiry Science Observation Coding Sheet

Evaluation reports increasingly document the degree of program implementation, particularly the extent to which programs adhere to prescribed steps and procedures. Many reports are cursory, however, and few, if any, fully portray the long and winding path taken when developing evaluation instruments, particularly observation instruments. In this article, we describe the development of an observational method for evaluating the degree to which K-12 inquiry science programs are implemented, including the many steps and decisions that occurred during the development, and present evidence for the reliability and validity of the data that we collected with the instrument. The article introduces a method for measuring the adherence of inquiry science implementation and gives evaluators a full picture of what they might expect when developing observation instruments for assessing the degree of program implementation.     

SOGS and CGPI: Parallel Comparison on a Diverse Population

The Northern Territory of Australia, one of the most demographically and socially diverse jurisdictions in the country, conducted its first population-based gambling and problem gambling prevalence survey in 2005. Both the South Oaks Gambling Screen (SOGS) and the Canadian Problem Gambling Index (CPGI) were administered to the same sample of respondents. Using data from this survey, the current paper presents a parallel comparison of the respective screens with particular reference to gender, region, and the socio-demographic characteristics of respondents. The respective screens produced significantly different groups of problem gamblers as measured by their association with a range of socio-demographic variables. Specifically, the large number of SOGS items related to money issues may cause selective overrepresentation among low socioeconomic groups, including Indigenous people, who exist in relatively high proportions in the Northern Territory. In addition, there existed substantial gender-based differences within screens. Identified female problem gamblers were associated with household level variables (i.e. employment status, household type and marital status), while males were associated with socio-economic variables including language, education, and income. Further research is required to validate the use of problem gambling screens within the Indigenous population and to understand the role of gender in the experience and categorisation of problem gambling.     

Sequential Search and Selection Problem Under Uncertainty

This paper formulates and discusses a series of sequential decision problems of the following common structure: A decision alternative of multiple attributes‐that is, a job, an employee, or an investment alternative‐is to be selected within a certain fixed length of time. An unknown number of alternatives are presented sequentially, either deterministically or in a random manner. The decision maker can rank all the alternatives from best to worst without ties, and the decision to accept or reject an alternative is based solely on the relative ranks of those alternatives evaluated so far. The nonparametric sequential decision problem is first studied for a model involving a discrete time period and then generalized in terms of continuous time. Also considered is a variant of this problem involving a Bayesian estimation of (1) the uncertain probability of having an alternative at a given stage in the discrete‐time model and (2) the arrival rate of alternatives in the continuous‐time model. The optimal selection strategy that maximizes the probability of selecting the absolute best alternative is illustrated with the job search problem and the single‐machine job assignment problem.     

An Ecological Regional Analysis of South Carolina

This study of the counties of South Carolina introduces a limited purpose, modifiable technology that is designed to reproduce the rapid discovery strategy of the natural sciences. It uses factor analysis to identify types of communities and the threats they face, and evaluates their success in dealing with these by comparisons based on age-adjusted mortality rates. The factor analysis of mostly census indicators generated an Urbanization factor along with two measures of the interaction with the environment, Growth and Poverty. Growth was expected to predict mortality negatively while Poverty should predict positively. Regression analysis confirms both predictions but only for each race. That is, Growth predicted lower mortality, but only for African-Americans. Poverty predicted higher mortality, but only for whites. These and other puzzling findings are explored, illustrating the “rapid discovery” technology that is the central feature of this paper.     

Exploring crisis communication in the internal context of an organization: Examining moderated and mediated effects of employee-organization relationships on crisis outcomes

This study seeks to foster a greater understanding of effective crisis communication from the internal context of organizations. The present research conducted an online experimental study of 640 full-time employees in the United States. Results through OLS multiple regression and path analysis indicated 1) employee-organization relationships (EOR) and timing strategy of self-disclosure (stealing thunder) were positively associated with the positive internal reputation and employees’ supportive behavioral intentions, 2) the positive effects of EOR on the employees’ supportive behaviors appeared differently according to whether or not stealing-thunder was used, and 3) the effects of EOR and message strategy (accommodative response) on the positive internal reputation were varied when the negative emotions (anger and anxiety) intervened.     

Likelihood inference for dynamic linear models with Markov switching parameters: on the efficiency of the Kim filter

The Kim filter (KF) approximation is widely used for the likelihood calculation of dynamic linear models with Markov regime-switching parameters. However, despite its popularity, its approximation error has not yet been examined rigorously. Therefore, this study investigates the reliability of the KF approximation for maximum likelihood (ML) and Bayesian estimations. To measure the approximation error, we compare the outcomes of the KF method with those of the auxiliary particle filter (APF). The APF is a numerical method that requires a longer computing time, but its numerical error can be sufficiently minimized by increasing simulation size. According to our extensive simulation and empirical studies, the likelihood values obtained from the KF approximation are practically identical to those of the APF. Furthermore, we show that the KF method is reliable, particularly when regimes are persistent and sample size is small. From the Bayesian perspective, we show that the KF method improves the efficiency of posterior simulation. This study contributes to the literature by providing evidence to justify the use of the KF method in both ML and Bayesian estimations.     

Sing for the Moment: A Choral Ensemble for Persons with Dementia and Their Care Partners

Research suggests that people with Alzheimer’s disease and other dementias receive various benefits from singing. This article describes the Sing for the Moment Choir, an ensemble comprised of persons with Alzheimer’s disease or related dementias, and their care partners. The choir is sponsored by the greater Pennsylvania Chapter of the Alzheimer’s Association. As the world’s leading voluntary health organization in Alzheimer’s care, support, and research, the Alzheimer’s Association is committed to raising awareness of this fatal brain disease. The program mission statement is: “the Sing for the Moment Choir provides persons with Alzheimer’s disease and related dementia and their care partners an opportunity to socialize, connect and inspire others through singing.”     

Exploring trust and distrust as conceptually and empirically distinct constructs: Association with symmetrical communication and public engagement across four pairings of trust and distrust

Existing relationship research has interpreted low trust as being equivalent to high distrust and high trust as the evidence of low distrust, which has failed to capture the full scope of the functions of trust and distrust in organization–public relationships. Recent research in this area suggests that trust and distrust might simultaneously exist during relational interactions and might play uniquely positive and negative functions in certain social contexts. The main purpose of this study was to offer a new insight in trust–distrust research by providing distinctions in conceptualization and operationalization between trust and distrust. This study also empirically tested the functions of four pairings of trust and distrust on two core public relations concepts (i.e., symmetrical communication and public engagement). The results from the surveys (N = 704; in 20 companies) of US consumers showed sound discriminant validity of trust and distrust. Further, the statistical results revealed that symmetrical communication and public engagement were most strongly associated with the high trust and high distrust pairing, supporting the utilities of distrust in public relations and the coexistence of trust and distrust in social interactions.     

Agenda-Building role of state-owned media around the world: 2014 Hong Kong protest case

ABSTRACT

This study aimed to advance theoretical and practical knowledge of political public relations and mediated public diplomacy through analyzing the agenda-building relationships between state-owned media and foreign news coverage in 16 countries during the 2014 Hong Kong protest. The results indicated significant correlations of issues and stakeholders between the Chinese state-owned media and the English language media outlets of 16 foreign countries, thereby supporting the international agenda-building role of Chinese state-owned media. An exploratory analysis was conducted to test the role of intercultural or international relations variables in the agenda-building process.
