The immunoenhancing effects of humor on secretory IgA and resistance to respiratory infections

Abstract

In three different studies involving exposun to two differcot humorous and comparison videotapes, it was demonstrated that humor arousal signiticantly increases S-IgA in college students. Furthermore significantly more of the subjects exposed to the humor films showed an increese in S-IgA than the subjects exposed to the comparison films. A good sense of humor, measured as a trait, was associated with higher baseline concentrations of S-IgA and with greater increases in S-IgA in response to a humor arousing film. Higher bascline kvels and gains in S-IgA in respoase to humor were associated with lower reported severity of colds in the past twelve months and in the three months following assessment. However, a good sense of humor was related to lesser cold incidence and severity only if it involved appreciation rather than production of humor. While those who actively tell jokes also show higher S-IgA levels, they show greater susceptibility to colds than those who only appreciate humor probably because they sodalize more often under conditions that expose them more to cold infections.     

Functional neuroimaging of working memory in survivors of childhood brain tumors and healthy children: Associations with coping and psychosocial outcomes

Purpose: Pediatric brain tumors are the second most common cancer diagnosis in individuals under age 20 and research has documented significant neurocognitive, psychosocial, and emotional late effects. Associations among these deficits have not been adequately considered and the role of survivors’ coping with stress in relation to deficits is unknown. Further, research has yet to examine neurobiological processes related to neurocognitive, psychosocial, and emotional difficulties in survivors through the use of functional neuroimaging. Method: Questionnaire measures and functional neuroimaging were used to examine the neurocognitive, psychosocial, and emotional functioning and coping responses of survivors of pediatric brain tumors (N = 17; age 8–16) and healthy children (N = 15). Results: Survivors experienced elevated levels of psychosocial and behavioral/emotional difficulties relative to healthy controls and normative data. Increases in brain activation in prefrontal and other anterior regions in response to a working memory task were associated with better psychosocial functioning, use of engagement coping strategies, and less use of disengagement coping strategies. Regression analyses suggest coping accounts for a significant portion of the association between brain activation and behavioral/emotional functioning. Conclusions: This study extends late-effects research by examining neurobiological processes associated with psychosocial and emotional difficulties. These findings contribute to our understanding of difficulties in survivors and provide a foundation for research exploring these associations and mediators of deficits in future longitudinal studies.     

A localist solution to the regress of epistemic justification

Guided by an account of the norms governing justificatory conversations, I propose that person-level epistemic justification is a matter of possessing a certain ability: the ability to provide objectively good reasons for one's belief by drawing upon considerations which one responsibly and correctly takes there to be no reason to doubt. On this view, justification requires responsible belief and is also objectively truth-conducive. The foundationalist doctrine of immediately justified beliefs is rejected, but so too is the thought that coherence in one's total belief system is sufficient, or indeed necessary, for justification. The problem of the regress is solved by exploiting the ‘localist’ idea that in order to possess the ability to justify any given belief, one only needs to be in a position to draw upon appropriate justified background beliefs to provide good reasons for holding the belief; one needn't be able to defend the relevant background beliefs, and so on, all at one sitting.     

Knowledge: Value on the Cheap

We argue that the so-called ‘Primary’ and ‘Secondary’ Value Problems for knowledge are more easily solved than is widely appreciated. Pritchard, for instance, has suggested that only virtue-theoretic accounts have any hopes of adequately addressing these problems. By contrast, we argue that accounts of knowledge that are sensitive to the Gettier problem are able to overcome these challenges. To a first approximation, the Primary Value Problem is that of understanding how the property of being knowledge confers more epistemic value on a belief than does the property of being true. The Secondary Value Problem is one of understanding how, for instance, the property of being knowledge confers more epistemic value on a belief than does the property of being jointly true and justified. We argue that attending to the fact that beliefs are continuing states reveals that there is no difficulty in appreciating how knowledge might ordinarily have more epistemic value than mere true belief or mere justified true belief. We also explore in what ways ordinary cases of knowledge might be of distinctive epistemic value. In the end, our proposal resembles the original Platonic suggestion in the Meno that knowledge is valuable because knowledge is somehow tied to the good of truth.     

The Curricula of Tibetan Buddhist Commentarial Schools (bshad grwa): Traditional Models and Some Recent Adaptations

This article examines commentarial schools (bshad grwa) within the non-Gelug traditions of Tibetan Buddhism, especially their normative curriculum of ‘thirteen great texts’ promoted—though not necessarily first conceived—by Khenpo Zhenpen Nangwa (1871–1927). Focused on Indian ?āstra, this ideal curriculum omits Tibetan works, tantras and texts on logic and epistemology (pramā?a), and represents the main body of an exoteric curriculum that could be preceded by basic introductory topics and augmented by advanced esoteric study. Recent adaptations of this curriculum by some of the most important non-Gelug institutions in exile depart from Zhenpen Nangwa's non-sectarian ideal in order to accommodate the texts, topics and interpretations favoured by the tradition to which the institution belongs. The article concludes by asking whether further changes to traditional curricula and pedagogy are likely, following the introduction of new qualifications adopted from the Indian university system and developments such as the creation of commentarial schools for international students.     

Improved training of football referees and the decline in home advantage post-WW2

ObjectivesResearch has identified a decline in home advantage (HA) in a number of professional leagues since World War 2 (WW2). The purpose of the current study was to identify whether the decline in HA in English and Scottish Professional Football Leagues is mirrored by the radical transformation in the training of referees post-WW2, thus providing a new insight into the cause of HA.DesignA longitudinal quasi-experimental design.MethodsHA was calculated for each team at the end of every season for the four English and the Scottish Premier League post-WW2. We also compiled a list of events, statements and quotations to illustrate the dramatic change in the way referees have been trained (physically and psychologically), and assessed over the same period.ResultsWe observed a systematic decline in HA in professional English and Scottish leagues post-WW2, but with the steepest decline observed in lower divisions with smaller crowds. Of the factors thought to influence HA, crowd support appears the most consistent with these observations. Crowds are known to influence referees' decisions to favour the home side. However we argue that improved training of referees since WW2 has contributed to an improved ability to make objective decisions and a greater resilience to crowd influence, which explains the decline in HA but also accounts for the steeper decline observed with smaller crowds.ConclusionsThe continued existence of HA, and the less steep decline observed in top leagues suggests that referees' judgements are still not immune to the influence of larger crowds.     

The Blood of Jesus in revival theology and the contemporary Church with particular reference to the East African Revival and Roy Hession

One of the most common phrases heard in testimony, preaching, and song during the East African Revival (EAR) was the phrase ‘The Blood of Jesus Christ’. Taken from a rich biblical heritage, this phrase encapsulates a wide range of ideas concerning the work of the cross and the power of forgiveness in a believer's life. Whilst, as will be noted, the use of The Blood has been common to many revivals, this article examines especially the theology behind this phrase by looking at the most prominent of the EAR authors – Roy Hession. It investigates seven different applications of The Blood in a believer's life: The Blood as a testament that sin is forgiven, The Blood as cleansing the conscience, The Blood as victory over despair, The Blood as the remover of shame, The Blood as washing away sin, The Blood as the gateway of the Holy Spirit, and finally The Blood as the source of true fellowship. The theology of The Blood has a long history of use in the Church but it also comes with difficulties. To this end the article will investigate the legitimacy of the practice often found in Africa and some Pentecostal circles of invoking The Blood as protection against the demonic. The article closes by considering the reasons why speaking of The Blood in church can be uncomfortable yet is paradoxically of vital importance to revival.
