Gaussian Process Regression and Bayesian Model Averaging: An Alternative Approach to Modeling Spatial Phenomena

Abstract: Gaussian Process Regression (GPR) is a nonparametric technique that is capable of yielding reliable out-of-sample predictions in the presence of highly nonlinear unknown relationships between dependent and explanatory variables. But in terms of identifying relevant explanatory variables, this method is far less explicit about questions of statistical significance. In contrast, more traditional spatial econometric models, such as spatial autoregressive models or spatial error models, place rather strong prior restrictions on the functional form of relationships, but allow direct inference with respect to explanatory variables. In this article, we attempt to combine the best of both techniques by augmenting GPR with a Bayesian Model Averaging (BMA) component that allows for the identification of statistically relevant explanatory variables while retaining the predictive performance of GPR. In particular, GPR-BMA yields a posterior probability interpretation of model-inclusion frequencies that provides a natural measure of the statistical relevance of each variable. Moreover, while such frequencies offer no direct information about the signs of local marginal effects, it is shown that partial derivatives based on the mean GPR predictions do provide such information. We illustrate the additional insights made possible by this approach by applying GPR-BMA to a benchmark BMA data set involving potential determinants of cross-country economic growth. It is shown that localized marginal effects based on partial derivatives of mean GPR predictions yield additional insights into comparative growth effects across countries.

Attitudes towards American brands and Brand America

Abstract: A study of 556 students at colleges and universities in Australia, Hong Kong and Singapore explored the relationship between attitude towards the United States and brand attitudes and preferences. Singaporean student attitudes towards both the US Government and US people were higher than were those of the Australian and Hong Kong students. Coke, Nike and McDonald's were among both the most-liked and disliked US brands among the international students, a finding suggesting that brands may possess both a 'lovemark' status, as described in the literature, and its opposite — 'loathemark' status — within the same demographic group. US brand preference scores did not offer support for the belief that international consumers 'vote with their pocketbooks' by refusing to purchase US brands if they have a negative attitude towards the United States. Among Hong Kong and Singaporean students, favourable attitudes towards the purchase of US brands was found to be positively related to favourability towards the US Government.

Power mobility for children: a survey study of American and Canadian therapists’ perspectives and practices

Abstract: Aim To explore the views and practices of paediatric occupational therapists and physical therapists in Canada and the USA regarding the implementation of power mobility for children with mobility limitations. Method This descriptive study utilized a web-based survey that included questions pertaining to therapists' decisions to trial and use power mobility, agreement or disagreement with statements developed from published practice considerations regarding power mobility, and the frequency of performing tasks related to power mobility prescription and training. Results Most respondents reported that child characteristics (e.g. cognition, safety awareness) were important factors in decision-making about power mobility, whereas other child characteristics (e.g. communication abilities, age) were not as important. Family resources and home accessibility were also not considered important. The average age at which respondents considered power mobility for children was 2 years 3 months. The majority of respondents agreed with statements developed from published practice considerations and most frequently performed various power mobility tasks twice a year or less. Interpretation Although most respondents appeared to have positive views regarding power mobility, few appeared to actively perform power mobility tasks in their practice. Resources to support therapists in the early introduction of power mobility may be beneficial. What this paper adds Occupational and physical therapists positively view early introduction of power mobility for children with mobility limitations. Few therapists actively provide early power mobility experiences. Power mobility training and monitoring power mobility devices are important therapist roles.

The NLSY Kinship Links: Using the NLSY79 and NLSY-Children Data to Conduct Genetically-Informed and Family-Oriented Research

Abstract: The National Longitudinal Survey of Youth datasets (NLSY79; NLSY-Children/Young Adults; NLSY97) have extensive family pedigree information contained within them. These data sources are based on probability sampling, a longitudinal design, and a cross-generational and within-family data structure, with hundreds of phenotypes relevant to behavior genetic (BG) researchers, as well as to other developmental and family researchers. These datasets provide a unique and powerful source of information for BG researchers. But much of the information required for biometrical modeling has been hidden, and has required substantial programming effort to uncover-until recently. Our research team has spent over 20 years developing kinship links to genetically inform biometrical modeling. In the most recent release of kinship links from two of the NLSY datasets, the direct kinship indicators included in the 2006 surveys allowed successful and unambiguous linking of over 94 % of the potential pairs. In this paper, we provide details for research teams interested in using the NLSY data portfolio to conduct BG (and other family-oriented) research.

Stakeholder valuing: A process for identifying the interrelationships between firm and stakeholder attributes

Abstract: As firms are creating and recreating themselves as stakeholder corporations, tensions mount between a firm’s fiduciary duties to its shareholders and the broader responsibilities inherent in a stakeholder focus. Firms have employed several techniques to help resolve this tension with limited success. We suggest that the next step in reducing this tension is formally accounting for stakeholder value through changes in financial reporting. We contend that stakeholders have a financial value to the firm that can and should be accounted for through the firm’s financial reporting system. We propose a three-step process we call stakeholder valuing (SV) to begin a conversation regarding how such a method can be created. SV begins with codifying the firm’s identity as a stakeholder entity, moves to assessing stakeholder value that’s consistent with that identity, and concludes with accounting for and reporting that value. What we are suggesting will be seen by some as a radical change in accounting practices but we believe it is necessary as we move toward a consistent, reliable, verifiable, transparent, and comparable means of accounting for the true value of a stakeholder corporation.
