The influence of external stimulation on airflow detection by children with asthma

Abstract

The relevance and significance of the concept of a ‘competition of cues’ for the understanding of symptom perception in childhood asthma was investigated during detection of externally applied resistive loads on breathing. The concept predicts that subjects would respond less frequently and less accurately during external stimulation. The sample consisted of 36 children with and 36 without asthma, aged 7-18 years. Detection of airflow was measured in a neutral and in an external stimulation condition. The children breathed through a facemask and responded to changes in airflow by pressing a button. The stimulus presented and withdrawn was analogous to a decrease in lung function (Forced Expiratory Volume in one second) of 39%. Accuracy of detection of airflow was defined as correct minus false positive responses to load stimuli.

The results showed that children with and without asthma responded significantly less frequently during external stimulation than in the neutral condition. However, the accuracy of detection among non-asthmatics was not affected by external stimulation. Children with asthma responded significantly more accurately during external stimulation. The results are discussed in the light of children's accuracy to perceive actual airways obstruction.     

The Second Vatican Council 50th anniversary: visions and re-visions

On 21 November 2014, the 50th anniversary of the solemn promulgation of Lumen Gentium and Unitatis Redintegratio was celebrated. Between ‘aggiornamento’ and ‘ressourcement’ the Catholic Church had been striving to understand itself and its Tradition more precisely, in order to be newly relevant, lastingly true and authoritative in the future ? an indispensible task, if the gospel were to be proclaimed to the contemporary world, but not an easy one. It is little wonder that this completion of the Council's endeavours was preceded by its so-called ‘black week’. Questions remain as to the outcome of it all, and the articles assembled in this issue assess the reception of these two conciliar texts after 50 years. Where do the achievements lie? Where are the shortcomings? Where do questions need to be asked today that reach beyond the horizon of Vatican II?     

Do Childhood Externalizing Disorders Predict Adult Depression? A Meta-Analysis

Childhood externalizing disorders have been linked to adult affective disorders, although some studies fail to substantiate this finding. Multiple longitudinal cohort studies identifying childhood psychopathology and their association with adult psychiatric illness have been published. To examine the association between childhood externalizing symptoms or disorders and the development of adult depression across cohorts, a meta-analysis was performed. Potential studies were identified using a PubMed search through November 2013. All published, prospective, longitudinal, community-sampled cohort studies of children (≤ 13 years) with externalizing symptoms or disorders (aggression, conduct problems, oppositional defiant disorder, conduct disorder), reassessed in adulthood (≥ 18 years) for depressive disorders (major depressive disorder, depressive disorder NOS, or dysthymic disorder) were included. A random effects model was used to summarize the pooled effect sizes. Ancillary analyses considered covariates that could account for variance among studies. Ten studies representing eight cohorts of children initially assessed at age 13 or younger (N?=?17,712) were included in the meta-analysis. Childhood externalizing behavior was associated with adult depressive disorders (OR?=?1.52, 95 % confidence interval?=?1.27–1.80, p?相似文献   

The ecumenical vision of Pope Francis: journeying together as fellow pilgrims − ‘the mystery of unity has already begun’

After reviewing some of the unique ecumenical steps taken by Pope Francis, this article examines briefly the three ecumenical paragraphs in Evangelii Gaudium. It presents them in the wider context of this post-synodal exhortation, of the ecumenical gestures and testimonies of Pope Francis, the ecumenical orientation of the Catholic Church and the ecumenical movement as such. It concludes with an outlook on a newly emerging ecumenical paradigm.     

Most Precious Blood: pilgrimage and veneration of the relic in Weingarten and Mantua

This contribution reflects on the indissoluble connection between Christ and the Church which becomes tangible in his redeeming blood. It gives an overview of the papal teaching on the veneration of the Precious Blood and explores what the connections, parallelisms and differences are that exist between Mantua and Weingarten regarding the devotion to parts of the same relic.

Dating Violence Prevention: A Didactic Support Group for Young Women

The authors discuss the social problem of dating violence and present a didactic support group model designed to empower young women to see themselves as “choice makers” with the ability to make informed decisions in their own best interest. They also present research findings that support the content of the group model and articulate some of their experiences in conducting this group in both high school and college settings. Finally, they discuss the potential impact of the group according to feedback from participants.     

Tone sequences with conflicting fundamental pitch and timbre changes are heard differently by musicians and nonmusicians

An Auditory Ambiguity Test (AAT) was taken twice by nonmusicians, musical amateurs, and professional musicians. The AAT comprised different tone pairs, presented in both within-pair orders, in which overtone spectra rising in pitch were associated with missing fundamental frequencies (F0) falling in pitch, and vice versa. The F0 interval ranged from 2 to 9 semitones. The participants were instructed to decide whether the perceived pitch went up or down; no information was provided on the ambiguity of the stimuli. The majority of professionals classified the pitch changes according to F0, even at the smallest interval. By contrast, most nonmusicians classified according to the overtone spectra, except in the case of the largest interval. Amateurs ranged in between. A plausible explanation for the systematic group differences is that musical practice systematically shifted the perceptual focus from spectral toward missing-F0 pitch, although alternative explanations such as different genetic dispositions of musicians and nonmusicians cannot be ruled out.

Direct and Indirect Assessment of Gender Role Identification

Differences in gender role identification exist among both men and women. Earlier researchers have developed several instruments to measure the degree to which individuals identify with the masculine or feminine gender role. In the present study we examined a number of these measurement procedures. Undergraduate students (N?=?45) were administered three direct and two indirect measures of gender role identification. In addition, participants were exposed to a psychological stress test that was relatively masculine. Findings reveal that direct and indirect instruments tap different underlying constructs of gender role identification that are nevertheless positively correlated. Furthermore, results suggest that one of the indirect measures, the Gender Implicit Association Test (GIAT), is a promising instrument to provide an estimate of gender role identification. Of all gender role identification measures the GIAT was (a) most sensitive to sex differences and (b) the only significant predictor of systolic blood pressure responses during and after the relatively masculine stress task.     

Separate or together? Women-only public spaces and participation of Saudi women in the public domain in Saudi Arabia

Gender segregation in the public domain has become a cornerstone of the Saudi interpretation of Islam (Doumato 2009). It is a development that has led to the coming about of extensive separate public spaces that are only for women (Doumato 2009; Hamdan 2005; Le Renard 2008, 2014). In these women-only public spaces, women undertake activities that are by them and for them, therewith reinforcing the existence of these separate structures. This institutionalisation and practice of women-only public spaces, as well as its opposite phenomenon of ‘mixing’ between the two sexes (ikhtilā?) however is contested and led to a heated debate. This debate centres around the question of whether and if so, how women should participate in the public domain. Starting with an overview of the historical development of women-only public spaces and ikhtilā? in Saudi Arabia, I will show how these have evolved. Drawing on fieldwork among urban, educated Saudi women, I shed light on how attitudes and strategies of female respondents regarding women-only public spaces and ikhtilā? are related to their ideas about their presence in the public domain and notions of ‘the liberation of women’, ‘empowerment’, and ‘the rise of women’. I conclude by demonstrating how ideas about the participation of women in the public sphere are positioned as part of the construction of a local, ‘enchanted’ modernity (Deeb, 2006) that has a material and a spiritual dimension.
