A remote-controlled device for long-term blood collection from freely moving, socially housed animals

A remote-controlled device was developed for injection of fluids and collection of blood samples from freely moving, socially housed animals via an indwelling catheter. Samples are collected at times chosen by the investigator, and the animal is not aware that sampling is occurring. This technique allows measurement of plasma catecholamines and other substances that fluctuate rapidly, are affected by psychosocial stimuli, and are altered by capture and other stressful activities that often accompany sample collection. Rapid retrieval of samples is facilitated by remote-controlled injection of an anesthetic. The device has been used to collect blood from dominant and subordinate male baboons before and during events such as chases and presentation of food treats. Heart rate and blood pressure were measured via radio telemetry, and behavior was recorded on videotapes. This technique allowed construction of multifaceted physiological profiles of social roles and behaviors.     

Afterword: some reflections on implicit religion and ordinary theology

This brief piece relates Edward Bailey's concept of implicit religion, together with some themes from the papers published in this special issue, to Astley's concept of ordinary theology. In particular, it attends to their different, but overlapping, focal concerns and their shared emphasis on a spiritual core of personal meaningfulness.     

Teaching Theology to Undergraduates: Are mature students easier to please?

A total of 1,687 course evaluation questionnaires, submitted by students attending undergraduate programmes in theology, indicated some significant age-related differences in responses. Overall, mature students displayed a higher level of appreciation for the lecturers, although they tended to be more critical when opportunities were not given for an interactive learning experience.     

Superordinate category formation in pigeons: association with a common delay or probability of food reinforcement makes perceptually dissimilar stimuli functionally equivalent.

Training associated pairs of perceptually dissimilar stimulus classes with a common delay or probability of food reinforcement in pigeons. Then, different choice responses were trained to 1 component class in each pair. In a choice test, the untrained class in each pair occasioned the same response as did the choice-trained class. In a 3rd experiment, 2 classes had reinforcement delays of 1 s and 15 s, respectively, and 2 other classes had reinforcement probabilities of 0.1 and 0.9. Then, 1 choice response was reinforced to a class previously associated with a better condition of reinforcement (e.g., 1-s delay or 1.0 probability), and a different response was reinforced to a class previously associated with a worse condition of reinforcement (0.1 probability or 0-s delay). Testing with all classes suggested that categorization was based on the relative reinforcement or hedonic value and not on the parametric details of reinforcement.     

Introducing the Astley–Francis Theology of Religions Index: construct validity among 13- to 15-year-old students

The ‘theology of religions’ is concerned with the interpretation and evaluation of the divergent truth-claims and views of salvation that are asserted or implied by different religious traditions. This study proposes a new multi-choice index that distinguishes between six current positions within the theology of religions, characterised as Atheism, Agnosticism, Exclusionism, Inclusivism, Pluralism, and Interreligious perspective, with a further subdivision between two expressions of the pluralism perspective. The construct validity of this new measure is supported by the performance of the instrument in respect of a network of theories (regarding how these different positions may relate to the factors of sex, age, personal religiosity and attitude toward religious diversity) among a sample of 10,754 13- to 15-year-old students from England, Northern Ireland, Scotland and Wales.     

Doubts on Spirituality: Interpreting Waldorf ritual

To investigate whether some kinds of kindergartens are better than others at bringing order, calm and stability to children's lives is, though not without its problems, fairly straightforward: the kinds of behaviour that count as evidence are relatively uncontroversial. Researchers can apply themselves, without too many qualms, to figuring out how kindergartens do it. Where spiritual development is concerned, because many kindergartens are already differentiated by religious or spiritual orientation - Jewish, Roman Catholic, Muslim, Waldorf, etc. - there is a temptation similarly to focus on how it is achieved. Relationships between the approaches and distinctive methodologies are prime areas for investigation. But such research might be premature. Any answer to the question 'To what extent have children been spiritually changed?' needs some agreement on the kinds of things we take as evidence of spiritual change. There are few signs of such agreement. This presents researchers, and also teachers, with a problem in proving their claims. In this article we try to substantiate this doubt by reflecting on some of our own research on Waldorf education. It too focused on 'how' and identified 'ritual' as a crucial factor in the Waldorf approach but we gradually realized that the epistemological issue was prior and had to be addressed.     

Superordinate categorization via learned stimulus equivalence: quantity of reinforcement, hedonic value, and the nature of the mediator

Three experiments examined superordinate categorization via stimulus equivalence training in pigeons. Experiment 1 established superordinate categories by association with a common number of food pellet reinforcers, plus it established generalization to novel photographic stimuli. Experiment 2 documented generalization of choice responding from stimuli signaling different numbers of food pellets to stimuli signaling different delays to food reinforcement. Experiment 3 indicated that different numbers of food pellets did not substitute as discriminative stimuli for the photographic stimuli with which the food pellets had been paired. The collective results suggest that the effective mediator of superordinate categories that are established via learned stimulus equivalence is not likely to be an accurate representation of the reinforcer, neither is it likely to be a distinctive response that is made to the discriminative stimulus. Motivational or emotional mediation is a more likely account.
