Peripheral control of drinking: gastrointestinal filling as a negative feedback signal, a theoretical and experimental analysis.

The studies described here investigated the hypothesis that the osmotic postingestional satiety signal proposed by McCleary operates through a mechanism related to gut filling rather than by osmotically induced shifts of fluid from osmoreceptors in the brain. A control theory model is presented, which was designed to make quantitatively explicit the hypothesis under question. The results showed that when mannitol, which is not absorbed from the intestine, is added to a highly palatable saccharin-glucose mixture, the amount of fluid consumed decreased in inverse proportion to the mannitol concentration. Mannitol was also shown to block fluid absorption from the intestine at a low concentration (approximately .070 M) and at higher concentrations to lead to a net flux of fluid into the intestinal lumen. It was also shown that mannitol in concentrations that reduced the intake of the palatable solution did not induce thirst when the animals were in water balance. It did induce thirst, however, when the animals were tested in a state of negative water balance. The results of these studies, considered as a whole, support the view that McCleary's osmotic postingestional satiety signal acts as an intestinal distention signal rather than by inducing thirst. The model is found to be reasonably accurate as a first approximation, and suggestions are made for improvements.     

Audience reaction as a determinant of the speaker's self-persuasion

This paper tests effects of audience feedback on speaker attitudes. One hundred and seven male subjects with initial beliefs on both sides of an issue (women's role) were assigned to speak for or against their own position; then an “audience” provided one of three types of feedback (speaker was sincere, speaker was insincere, no feedback) in a 2 × 2 × 3 design. Subjects who received sincere feedback showed greater change in the direction of their speech than did those who received insincere feedback. No feedback treatments resulted in intermediate change. This sincere > no feedback > insincere ordering of means held for both pro- and counterattitudinal speakers and for both pretest attitudes. A main effect for pretest attitude was also obtained. Two additional control groups allow for a separate analysis of the effects of (1) preparing and delivering the speech, and (2) audience reaction to the speech.     

Examination of efficacious,efficient, and socially valid error‐correction procedures to teach sight words and prepositions to children with autism spectrum disorder

Prior research shows that learners have idiosyncratic responses to error‐correction procedures during instruction. Thus, assessments that identify error‐correction strategies to include in instruction can aid practitioners in selecting individualized, efficacious, and efficient interventions. The current investigation conducted an assessment to compare 5 error‐correction procedures that have been evaluated in the extant literature and are common in instructional practice for children with autism spectrum disorder (ASD). Results showed that the assessment identified efficacious and efficient error‐correction procedures for all participants, and 1 procedure was efficient for 4 of the 5 participants. To examine the social validity of error‐correction procedures, participants selected among efficacious and efficient interventions in a concurrent‐chains assessment. We discuss the results in relation to prior research on error‐correction procedures and current instructional practices for learners with ASD.     

The role of anxiety sensitivity in the relationship between posttraumatic stress symptoms and negative outcomes in trauma-exposed adults

Background: The development of posttraumatic stress symptoms (PTSs) following a trauma is related to impairment, diminished quality of life, and physical health issues. Yet it is not clear why some trauma-exposed individuals experience negative outcomes while others do not. The purpose of this study was to determine the role of several influential factors related to PTS severity and negative outcomes. Methods: One hundred and twenty-two trauma-exposed adults were administered the following self-report measures: the Posttraumatic Stress Disorder Checklist-Civilian, the Trauma History Questionnaire-Short, the Anxiety Sensitivity Index-3, Depression and Anxiety Stress Scale 21, Sheehan Disability Scale, World Health Organization Quality of Life-BREF, and an abbreviated Patient Health Questionnaire. Primary Results: PTS severity was positively correlated with depressive symptom severity (r = 0.54, p < 0.001), chronicity of the most distressing trauma (r = 0.21, p = 0.017), and number of traumas (r = 0.22, p = 0.012). Main effects were found for PTS severity (β = ?0.38, p < 0.01) and anxiety sensitivity (AS; β = ?0.39, p < 0.01) on quality of life. No interaction was found between PTS severity and AS with any negative outcome. PTS severity mediated the relationship between AS and physical health issues (0.05; 95% CI: 0.02–0.08). Conclusion: This study helps clarify the role of various factors in the relationship between trauma and negative outcomes. Clinical and research implications are discussed.     

Identity Styles and Religiosity: Examining the Role of Identity Commitment

This study observed the role of identity styles, identity commitment, and identity statuses in predicting religiosity in a sample of undergraduate students attending a Seventh-day Adventist university (N = 138). Two structural models were evaluated via path analysis. Results revealed two strong models for the prediction of religiosity. Identity styles explained 24% of the variance in religiosity, with the relationship mediated by identity commitment. Religious identity status explained 56% of the variance in religiosity, with the relationship not mediated by identity commitment. Implications of these interactions for understanding religious identity development are discussed.     

A Multi-Study Examination of Well-Being Theory in College and Community Samples

Well-being theory (WBT) proposes five indicators of well-being [i.e., positive emotion, engagement, relationships, meaning, achievement (PERMA)] that are, independently, empirically supported predictors of flourishing (i.e., an optimal level of well-being; Seligman in Flourish: a visionary new understanding of happiness and well-being. Free Press, NY, 2011). However, there is limited empirical support for the multidimensional model suggested by WBT. Two studies sought to test and validate the higher-order factor structure of the five components of PERMA and PERMA’s ability to predict concurrent and prospective flourishing outcomes (e.g., physical health, college success). In Study 1, a longitudinal examination of college students, participants completed measures of well-being (including four of the five PERMA indicators), physical health, and college success at the end of their sophomore, junior, and senior years. In Study 2, a larger, cross-sectional study was conducted online to further validate the PERMA model with a broader sample and all five PERMA indicators. Participants completed measures similar to those administered at Study 1 and other measures used to validate Study 1 measures. Results from Study 2 further validated the PERMA model by comparing Study 1 measures to established measures and by adding meaning to the model. Study 1 and Study 2 PERMA models predicted markers of well-being (e.g., vitality, life satisfaction) and flourishing (e.g., physical health). The two studies reported here provide cross-sectional and longitudinal support that WBT is useful for predicting flourishing.     

The 2014 Agreed Statement on Christology of the Churches of the Anglican Communion and the Oriental Orthodox Churches: a Catholic review

This article discusses the sources of the 2014 Agreed Statement on Christology, which include not only the 433 Formula of Union and the teaching of St Cyril of Alexandria but also some language from the Council of Chalcedon (451), the Second Council of Constantinople (553), and the Third Council of Constantinople (680–681). It also examines the rejection of Eutychianism and Nestorianism, as well as the Anglican Christology represented by Richard Hooker and the firm connection drawn between the hypostatic union and Christ’s work of salvation. The article also presents the text in comparison and contrast with two Christological declarations shared by the Roman Catholic Church and the Coptic Pope Shenouda III (1973) and the Assyrian Church of the East (1994).
