A Romanian Contribution to Contemporary Ecumenism

This article examines the contribution to ecumenical dialogue of Ion Bria, an important Romanian theological and ecumenical personality. The value of his approaches is demonstrated by the fact that many contemporary authors start their research from his ideas, such as the concept of the “liturgy after the liturgy,” of which he was a significant proponent, and which are still relevant to ecumenical dialogue. At the time they were first proposed, they shifted ecumenical dialogue. Bria was also a good and careful observer of ecumenical and pan‐Orthodox reality. He presented with objectivity the reality from his home space and made valuable comparisons between his spirituality and other confessional approaches, offering new topics of dialogue and creating bridges between churches.     

Mission and People with Disabilities

This article begins with a few thoughts and some historical and canonical encounters about how lay and ordained people with disabilities have been involved in Orthodox mission work in the past. It then presents two concrete contemporary situations in which people with disabilities are involved in Orthodox ordained ministry work despite the persisting tradition that disabled people not be ordained. The first example is taken from the Eritrean Orthodox Tewahedo Church, where the involvement of people with disabilities in both ordained and lay ministry provides significant support for a church that lives in a delicate situation. The second example is taken from the Romanian Orthodox Church and presents the case of Father Theophilus P?r?ian, one of the most prominent contemporary Romanian Orthodox monastic figures, who served as an ordained priest despite his disability. This article pleads for a deeper involvement of disabled people in both ordained and lay ministry in Orthodox churches.     

Fostering Diversity in the Creative Arts by Addressing Students' Capacity to Aspire

Research on young people's aspirations and their capacity to aspire to higher education has proliferated in recent decades, however, very little attention has been paid to the creative arts. Diversity in the arts remains a persistent issue in many nations, and repeated attempts to promote diversity in the Australian arts community have had limited impact, suggesting the need for new approaches. Drawing on data from a 4‐year longitudinal study of students from ages 8 to 18 (n = 6,492) in government schools, we examine school students' aspirations for careers in the arts. Arts‐related careers were popular among students, yet we found a distinct lack of diversity among those aspiring to such careers. Using logistic regression analysis we found that being female, high achieving, from an English‐speaking background, possessing high cultural capital, and attending advantaged schools were significant predictors of interest in the arts, suggesting the likely reproduction of existing patterns of participation. We argue that initiatives within schools are essential to disrupting these patterns and building the capacity of a more diverse range of students to aspire to careers in the arts.     

Tests of an indifference rule in variable‐delay and double‐reward choice procedures with humans

Four hundred and fifty participants were recruited from Amazon Mechanical Turk across 3 experiments to test the predictions of a hyperbolic discounting equation in accounting for human choices involving variable delays or multiple rewards (Mazur, 1984, 1986). In Experiment 1, participants made hypothetical choices between 2 monetary alternatives, 1 consisting of a fixed delay and another consisting of 2 delays of equal probability (i.e., a variable‐delay procedure). In Experiment 2, participants made hypothetical monetary choices between a single, immediate reward and 2 rewards, 1 immediate and 1 delayed (i.e., a double‐reward procedure). Experiment 3 also used a double‐reward procedure, but with 2 delayed rewards. Participants in all 3 experiments also completed a standard delay‐discounting task. Finally, 3 reward amounts were tested in each type of task ($100, $1000, and $5000). In the double‐reward conditions (Experiments 2 and 3), the results were in good qualitative and quantitative agreement with Mazur's model (1984, 1986). In contrast, when participants made choices involving variable delays (Experiment 1), there was relatively poor qualitative and quantitative agreement with this model. These results, along with our previous findings, suggest the structure of questions in hypothetical tasks with humans can be a strong determinant of the choice pattern.     

Determinants of memory development in childhood and adolescence

Research on the development of memory has a long history and constitutes one of the most active research areas in the field of cognitive development. In this article, we first describe major historical developments in the literature on children's memory, focusing on systematic research that began in the late 1960s. We then examine new developments in the field, describing four important lines of inquiry: (a) the development of implicit memory, (b) short‐ and long‐term memory development in infancy, (c) longitudinal research on memory strategies and metamemory, and (d) developmental cognitive neuroscience of memory. Finally, promising lines of future research on memory development are briefly discussed.     

Out-of-bag Prediction Error: A Cross Validation Index for Generalized Structured Component Analysis

Cross validation is a useful way of comparing predictive generalizability of theoretically plausible a priori models in structural equation modeling (SEM). A number of overall or local cross validation indices have been proposed for existing factor-based and component-based approaches to SEM, including covariance structure analysis and partial least squares path modeling. However, there is no such cross validation index available for generalized structured component analysis (GSCA) which is another component-based approach. We thus propose a cross validation index for GSCA, called Out-of-bag Prediction Error (OPE), which estimates the expected prediction error of a model over replications of so-called in-bag and out-of-bag samples constructed through the implementation of the bootstrap method. The calculation of this index is well-suited to the estimation procedure of GSCA, which uses the bootstrap method to obtain the standard errors or confidence intervals of parameter estimates. We empirically evaluate the performance of the proposed index through the analyses of both simulated and real data.     

A New Multilevel CART Algorithm for Multilevel Data with Binary Outcomes

The multilevel logistic regression model (M-logit) is the standard model for modeling multilevel data with binary outcomes. However, many assumptions and restrictions should be considered when applying this model for unbiased estimation. To overcome these limitations, we proposed a multilevel CART (M-CART) algorithm which combines the M-logit and single level CART (S-CART) within the framework of the expectation-maximization. Simulation results showed that the proposed M-CART provided substantial improvements on classification accuracy, sensitivity, and specific over the M-logit, S-CART, and single level logistic regression model when modeling multilevel data with binary outcomes. This benefit of using M-CART was consistently found across different conditions of sample size, intra-class correlation, and when relationships between predictors and outcomes were nonlinear and nonadditive.     

The longitudinal relationships of interpersonal openness trait,hostility, and hostile attribution bias

While the relationship between personality, hostility, and hostile attribution bias (HAB) has been explored in previous studies, their longitudinal relationship is unclear, and no related study has utilized the indigenous Chinese personality. This research explored the longitudinal relationships of interpersonal openness (IO; an indigenous Chinese personality construct), hostility, and HAB. The 942 valid participants (38.5% male, mean age = 20.83, standard deviation = 1.04) were from six different provinces in China. Measurements were completed on two separate occasions (Times 1 and 2), with a 6-month interval. Results showed that IO has longitudinal effects on hostility, after controlling for the Big Five, and HAB could be longitudinally predicted by IO and hostility as well. Moreover, hostility served as a mediator in the relationship between IO and HAB. These results suggest that IO can affect the development of hostility and HAB, and some indigenous Chinese personality factors may complement Western personality theories.
