Physical activity and sedentary lifestyle in children as time-limited functions: Usefulness of the principal component analysis method

This study was designed to examine the hourly variation in and the interplay between physical activity and sedentary behavior (SB) in order to highlight key time periods for physical activity interventions for children. Data for physical activity and SB obtained with ActiGraph in 56 boys and 47 girls aged from 8 to 11 years. These data were divided into sixty minute-time samples for moderate-to-vigorous physical activity (MVPA) and SB, and analyzed using a principal component analysis (PCA) and correlation statistics. The PCA provides 10 factors which account for 80.4% of the inertia. Only two of these factors did not display competition between MVPA and SB. Contrary to some reports, a coefficient of correlation of -.68 (p < 10(-4)) was found between daily time spent at MVPA and SB. Some salient traits of children's behaviors were shown through PCA. The results suggested that efficacy of interventions targeting the morning hours (07:00 AM-11:59 AM) and the afternoon period (02:00 PM-05:59 PM) warrants attention.     

Oral cues improve subject‐verb agreement in written French

The aim of this study was to test the impact of an audible marker on the production of subject‐verb agreements. Earlier studies have shown that educated French‐speaking adults make subject‐verb agreement errors when writing as soon as a secondary task demands their attention. One hypothesis is that these errors occur primarily because in French many of the written inflections of the verbal plural are silent. However, errors of the same type have been reported in spoken English: in configurations such as “the dog of the neighbours arrive(s)”, arrive agrees with the noun closest to the verb rather than with the subject. The current experiment compares the production of subject‐verb agreements in written French depending on whether the singular/plural opposition is audible (finit/finissent) or not (chante/chantent). After having changed the tense of the verb, adult subjects had to recall, in writing, sentences which had been read aloud to them and which shared the same start (La flamme de la bougie = the flame of the candle) but contained different verbs matched for semantic plausibility and frequency, and either possessing (éblouir = to blind) or not possessing (éclairer = to illuminate) an audible singular/plural opposition. The results show that the presence of an audible marker reduces the error frequency and makes the agreement easier to manage. A chronometric study suggests that it is the competition between concurrent markers (e.g., ‐e, ‐s, ‐ent) that causes difficulties with regular verbs and that this competition is resolved at the very last moment, at the point when the marker is transcribed.     

Symbolism in Weakness: Jesus Christ for the Postmodern Age

The postmodern emphasis on human finitude encourages the reconsideration of religious traditions, and more particularly of Christianity. The doctrine of a vulnerable God dying on a cross speaks to postmodern civilization. Jesus Christ infuses transcendence into the realm of immanence by assuming the human predicament to its bitter end. The present essay critiques the recent attempts of deconstructionist philosopher John D. Caputo and systematic theologian Roger Haight to provide postmodern expositions for the Christian doctrine on the person of Jesus Christ. With the help of the fundamental notion of agapeic love, we demonstrate that in Jesus Christ, Caputo's philosophy of the event and Haight's theology of the symbol can be meaningfully integrated and human finitude responsibly overcome.     

Can we Build on Social Movement Theories to Develop and Improve Community‐Based Participatory Research? A Framework Synthesis Review

A long‐standing challenge in community‐based participatory research (CBPR) has been to anchor practice and evaluation in a relevant and comprehensive theoretical framework of community change. This study describes the development of a multidimensional conceptual framework that builds on social movement theories to identify key components of CBPR processes. Framework synthesis was used as a general literature search and analysis strategy. An initial conceptual framework was developed from the theoretical literature on social movement. A literature search performed to identify illustrative CBPR projects yielded 635 potentially relevant documents, from which eight projects (corresponding to 58 publications) were retained after record and full‐text screening. Framework synthesis was used to code and organize data from these projects, ultimately providing a refined framework. The final conceptual framework maps key concepts of CBPR mobilization processes, such as the pivotal role of the partnership; resources and opportunities as necessary components feeding the partnership's development; the importance of framing processes; and a tight alignment between the cause (partnership's goal), the collective action strategy, and the system changes targeted. The revised framework provides a context‐specific model to generate a new, innovative understanding of CBPR mobilization processes, drawing on existing theoretical foundations.     

Reliability and Validity of the Current Anxiety Level Measure

Professionals interested in assessing state anxiety (in the moment) levels before and after brief activity-based treatments would find limited evidence-based assessments. The purpose of this study was to develop and test the current anxiety level measure, a free, valid, and reliable state anxiety assessment. To establish concurrent validity, the current anxiety level measure was administered (n?=?98) alongside the State-Trait Anxiety Inventory. Results found a strong relationship (r?=?.904, p?r?=?.702, p?n?=?102). Both samples showed the current anxiety level measure to be reliable and valid.     

BIOLOGY TEACHERS’ CONCEPTIONS ABOUT THE ORIGIN OF LIFE IN BRAZIL,ARGENTINA, AND URUGUAY: A COMPARATIVE STUDY

Teachers’ conceptions about the origin of life in three Latin American countries with contrasting levels of secularism were analyzed: Argentina (Catholic constitution), Brazil (formally secular but not in practice), and Uruguay (consolidated secularism). A European survey questionnaire was used and the interpretation of the results drew on Barbour's four categories concerning the relationships of science and religion. A large majority of Argentinian and Uruguayan teachers were clearly evolutionist, even when believing in God (Independence or Dialogue category), with no difference between Argentina and Uruguay. The majority of Brazilian teachers assumed a religious position about the origin of life, being creationist (Conflict or Independence categories) or evolutionary creationist (Dialogue or Integration categories). Differences of Brazilian teachers’ conceptions may result from the higher percentage of evangelicals and lower proportion of agnostics/atheists. Brazilian Catholic teachers were more creationist than their Catholic colleagues in Argentina and Uruguay. Distinct patterns were found, but further research is needed to understand possible classroom impacts.     

Knowledge before Gettier

According to a historical claim oft-repeated by contemporary epistemologists, the ‘traditional’ conception of knowledge prevailed in Western philosophy prior to the publication in 1963 of Edmund’s Gettier’s famous three-page article ‘Is Justified True Belief Knowledge?’. On this conception, knowledge consists of justified true belief. In this article, I critically consider evidence for and against this historical claim, and conclude with a puzzle concerning its widespread acceptance.     

Association between obesity and suicide in woman,but not in man: a population-based study of young adults

The relationship between obesity and suicide risk is still unclear with controversial research results. The aim of this study is to investigate the relationship between obesity and suicide risk for men and women in a population-based study of young adults. This is a cross-sectional population-based study that identified young adults between 18 and 35 years of age. Suicide risk was investigated through the structured clinical interview Mini. Weight and height were assessed, and participants were classified as normal-weight body mass index (BMI < 30) or obese (BMI > 30). The prevalence of obesity was of 19.9% of the total sample (n = 1953). Obesity was more prevalent among women and participants between 27 and 35 years of age. Suicide risk was present in 13.0% of the sample and more prevalent among women. In our study we found an association between obesity and suicide risk for women, but not for men. Obesity was associated with a higher prevalence of suicide risk in women. Given the strength of the relationship between BMI and suicide, identifying the mechanisms associated with obesity, especially for women, can lead to new insights into the prevention of suicide risk     

Saccadic eye movements: what do they tell us about aging cognition?

Although the relationship between age-related cognitive decline and saccadic eye movement (SEM) deficits has been outlined, specific cognitive alterations underlying age-related changes in saccadic performance remain unclear. This study attempted to better understand the nature of aging effects on SEMs. We compared SEMs in younger and older adults in prosaccade (PS) and antisaccade (AS) tasks under gap, step, and overlap conditions. We also examined relationships between these performances and several neuropsychological scores. Twenty-eight younger adults (YA), 24 older adults under 65 years (OA_<65) and 24 over 65 years (OA_>65) of age completed a neuropsychological evaluation, PS and AS tasks. Our results showed that latencies, AS cost, time to correct AS errors, and uncorrected AS, increased with aging. YA showed higher overlap effects than OA_>65 and OA_<65. Importantly, correlations and regressions revealed close relationships not only between latencies and processing speed measures but also between the AS cost and the inhibition process measures. Correct saccades and the time to correct AS errors were closely related to the inhibition process and cognitive flexibility measures. These findings suggest that the progressive age-related decline of processing speed and executive attention are associated with, and can be highlighted though SEMs in PS and AS tasks.
