Companions in Presence: Animal Assistants and Eldercare

Honoring the scholarship and teaching of Professor William M. Clements, this critically reflective essay expands the possibilities for a ministry of presence. The paper argues that animals can be helpful companions in care with elderly adults. The author draws from experiential stories, object relations theory, process theology, and empirical studies, to argue the beneficial aspects of animal assistants for human care receivers and caregivers. A creation-inclusive relational theology informs strategies for care.     

Very brief exposure II: the effects of unreportable stimuli on reducing phobic behavior

This experiment compared the effects of exposure to masked phobic stimuli at a very brief stimulus-onset asynchrony on spider-phobic and non-phobic individuals. Participants were identified through a widely used questionnaire and a Behavioral Avoidance Test (BAT) with a live, caged tarantula to establish baseline levels of avoidance. One week later, they were individually administered one of two continuous series of masked images: spiders or flowers. Preliminary masking experiments showed that independent samples of participants from the same populations failed to recognize these stimuli. Participants in the main experiment reported ratings of subjective distress immediately before and after the exposure manipulation. Then they engaged in the BAT once again. Very brief exposure to images of spiders reduced phobic participants' avoidance of the tarantula. No effects were evidenced on subjective distress, or on non-phobic participants. Theoretical implications for the non-conscious basis of fear are discussed.     

The things that aren’t actually there

The standard Kripkean semantic theories for quantified modal logic allow the individuals that exist at other worlds to vary from those that exist at the actual world. This causes a problem for those who deny the existence of non-actual individuals. I focus on two prominent strategies for solving this problem, due respectively to Bernard Linsky and Edward Zalta (who identify the possible individuals with the actual individuals) and Alvin Plantinga (who identifies the possible individuals with the individual essences). I argue, contra various commentators, that both of these solutions are acceptable by the lights of those who deny the existence of mere possibilia.     

The Unity of Self at the Interface of the Animal Body and the Cultural System

The self is defined by unity, which must be constructed from multiple inner processes and representations. The unity is more a requirement of social life than of brain activities. The self exists at the interface between the physical body and the social system, which for humans includes culture. The three main aspects of the self are a network of information (sometimes called the self-concept), an interpersonal being (e.g., member of a group or relationship), and executive function (e.g., making decisions). For each of these, multiple inner processes and representations must be integrated to produce the unity of self. Conscious processing plays a key role in this integrative process, because it is a vital means by which different areas of brain and mind exchange information.     

Kullback–Leibler Information and Its Applications in Multi-Dimensional Adaptive Testing

This paper first discusses the relationship between Kullback–Leibler information (KL) and Fisher information in the context of multi-dimensional item response theory and is further interpreted for the two-dimensional case, from a geometric perspective. This explication should allow for a better understanding of the various item selection methods in multi-dimensional adaptive tests (MAT) which are based on these two information measures. The KL information index (KI) method is then discussed and two theorems are derived to quantify the relationship between KI and item parameters. Due to the fact that most of the existing item selection algorithms for MAT bear severe computational complexity, which substantially lowers the applicability of MAT, two versions of simplified KL index (SKI), built from the analytical results, are proposed to mimic the behavior of KI, while reducing the overall computational intensity.     

The <Emphasis Type="Italic">γ</Emphasis>-admissibility of Relevant Modal Logics I — The Method of Normal Models

The admissibility of Ackermann’s rule γ is one of the most important problems in relevant logic. While the γ-admissibility of normal modal logics based on the relevant logic R has been previously discussed, the case for weaker relevant modal logics has not yet been considered. The method of normal models has often been used to prove the γ-admissibility. This paper discusses which relevant modal logics admit γ from the viewpoint of the method of normal models.     

Civic Friendship

This paper seeks to examine the plausibility of the concept of ‘Civic Friendship’ as a philosophical model for a conceptualisation of ‘belonging’. Such a concept, would hold enormous interest for educators in enabling the identification of particular virtues, attitudes and values that would need to be taught and nurtured to enable the civic relationship to be passed on from generation to generation. I consider both of the standard arguments for civic friendship: that it can be understood within the Aristotelian typology as either a form of utility friendship or as a form of virtue friendship. I argue that civic friendship may not be the most appropriate model and that attempts to resolve the problems through looking on it as a political metaphor leave it unable to fulfil the function for which it was originally designed in Ancient Greece. Finally, I emphasize the need to carefully consider which particular metaphors we choose for civic relationships and how we subsequently use them.
