The physiology of the tunnel

Several theories to account for the origin of tunnel hallucinations and tunnel experiences near death are considered: (1) the idea of a real tunnel; (2) representations of transition; (3) reliving birth memories; (4) imagination; and (5) physiological origins. Three different physiological theories are considered that related the tunnel form to the structure of the visual cortex. All can account for much of the phenomenology of the tunnel experience, and all lead to testable predictions. It is argued that the tunnel experience involves a change in the mental model of the self in the world. Because of this, an experience of purely physiological origin, with no implications for other worlds or for survival, can nevertheless produce lasting changes in the sense of self and reduce the fear of death.     

Paternalism in the neonatal intensive care unit

Two factors are discussed which have important implications for the issue of paternalism in the neonatal intensive care unit (NICU): the physician's role as advocate for the patient; and the range of typical responses of parents who learn that their neonate has a serious illness. These factors are pertinent to the task of identifying those actions which are paternalistic, as well as to the question of whether paternalism is justified. It is argued that certain behavior by physicians which is often thought to be paternalistic is not in fact so. Furthermore, an argument in defense of paternalism which has largely been overlooked is presented. Examples are given to illustrate how paternalism actually arises in the NICU, and it is argued that paternalism is justified in some cases.     

IS THERE A DISTINCTIVE QUANTUM THEOLOGY?

Quantum mechanics (QM) is a favorite area of physics to feature in “science and religion” discussions. We argue that this is at least partly because the arcane results of QM can be deployed to make big theological claims by the linguistic sleight of hand of “register switching”—sliding imperceptibly from technical into everyday language using the same vocabulary. We clarify the discussion by deploying the formal mapping of QM into classical statistical mechanics (CSM) via the mathematical device of “Wick rotation.” This equivalence between QM and CSM suggests caution in claiming distinctiveness for quantum theologizing. After outlining two areas in which quantum insights nevertheless resonate with longstanding themes in theological reflection (hiddenness and visualizability), we suggest that both QM and CSM point to a theology of science in which scientists participate in the divine gaze on creation as imago Dei.     

SUBLIMINAL EXPOSURE TO DEATH-RELATED STIMULI INCREASES DEFENSE OF THE CULTURAL WORLDVIEW

Abstract— Three experiments reported here provide empirical support for the hypothesis derived from terror management theory that unconscious concerns about death motivate allegiance to cultural beliefs, Study 1, contrasted exposure to a subliminal death-related stimulus, a standard mortality-salience treatment, and a neutral subliminal stimulus, and found that both the subliminal and the standard reminder of mortality led to more favorable evaluations of people who praised subjects' cultural worldview and more unfavorable evaluations of those who challenged it Study 2, replicated this finding by comparing the effects of exposure to subliminal death stimuli and subliminal pain stimuli. Study 3, contrasted subliminal death stimuli, supraliminal death stimuli, and subliminal pain stimuli and found that only subliminal death stimuli produced these effects.     

Nurses' Anxieties about Biohazards as a Function of Context and Knowledge1

Final-year nursing students (N= 96) described their anxieties about biohazards, not only in relation to the occupational context of a hospital ward, but also in relation to their general life context. These contexts were reported to vary in the extent to which they permitted control over exposure to the two particular biohazards chosen for study: human immunodeficiency virus (HIV) and hepatitis B virus (HBV). The data showed that nurses' anxiety about contracting HIV infection varied significantly across the two contexts, while anxiety about contracting HBV infection did not. In the general life context, anxiety about HIV was greater than anxiety about HBV for all subjects. This difference was significantly greater for those with incorrect knowledge about objective HIV seroconversion rates than for those with correct knowledge.
