Does modality matter? A latent profile and transition analysis of sedentary behaviours among school-aged youth: The UP&DOWN study

ABSTRACT

The aims of this study were to identify profiles of sedentary behaviour (SB) patterns, based on leisure-time self-reported SB modalities (screen, educative, social, and relaxing) and to evaluate changes in these profiles over 2 years among Spanish youth aged 8–18 years. Latent profile analysis (LPA), a data-driven analytic approach, was used to identify groups of boys and girls (n = 1553; 48% girls; mean±SD age: 12.56 ± 2.49 y) with distinct SB profiles using the SB modalities (time/d) as input variables. Latent transition analysis, an extension of LPA that uses longitudinal data, was used to analyse 2-year changes in these profiles. At baseline, four and three SB profiles were found among boys (labelled: screen, educative, social, and relaxing) and girls (labelled: screen/social, educative, and relaxing), respectively. Overall, more girls (range: 48%-67%) had the same profile over time, than boys (40%-52%). Participants with a screen or relaxing SB profile at baseline were more likely to have an educative profile after 2 years. Youth with a social and an educative SB profile at baseline were more likely to transition to profiles characterized by higher screen and social SB, respectively. Using a novel and person-centered approach, this study identified gender-specific SB profiles that were moderately stable over time.     

Syllable-based reading improvement: Effects on word reading and reading comprehension in Grade 2

This study examined the effects of a syllable-based reading intervention for German second graders who demonstrated difficulties in the recognition of written words. The intervention focused on fostering word reading via syllable segmentation. The materials consisted of the 500 most frequent syllables typically read by 6- to 8-year-old children. The aims were to practice phonological recoding, consolidate orthographic representations of syllables, and routinize the access to these representations. Compared to children randomly assigned to a wait-list group, poor readers in the treatment condition showed significant improvements in standardized measures of phonological recoding, direct word recognition, and text-based reading comprehension after the 24-session intervention. Poor readers in the treatment condition also showed greater improvements in development of word recognition compared to children with efficient word recognition skills. The results provide evidence that a syllable-based reading intervention is a promising approach to increase struggling readers’ word recognition skills, which in turn will improve their reading comprehension.     

‘I would say nine times out of 10 they come to the LSA rather than the teacher’. The role of teaching assistants in supporting children's mental health

This research explored how seven primary school teaching assistants (TAs) experienced their role in supporting children's mental health. Interviews were analysed using Interpretative Phenomenological Analysis (IPA). The participants believed that they supported children's mental health and particularly referenced the close relationships that they formed with children. Throughout their accounts of supporting children, the TAs referenced helpful factors (e.g. support from other staff) and challenges (e.g. hierarchy) within the school system. Supporting children’s mental health was an emotional experience for the TAs; they discussed the rewarding element, however, the topic also elicited fear. The findings provide several implications for school staff and external professionals about how TAs can be supported in their role. These include involving TAs in training opportunities, providing TAs with supervision, considering communication systems in schools, and introducing a mental health policy.

幼儿乳酸阈值及无氧阈心率的初步研究

对33名幼儿乳酸阈及其心率值进行测定,结果显示:3～5岁幼儿AT时血乳酸水平显著低于成人及青少年;幼儿亚极量强度运动后乳酸峰值大多出现在负荷后1min,反映了幼儿机体代谢的特异性.此实验结果可为幼儿有关生理机能和能量代谢的研究提供参数,所测得的乳酸阈心率值将为幼儿健身、减肥、增高等运动处方中运动强度控制提供科学依据.     

议广告中被物化了的女性形象

女性形象在现代广告中占有极高的比例,这种现象恰恰表明了社会处于男性文化的象征秩序,以男性话语作为尺度和标准,偏执地体现着男性话语的霸权地位,反映出男人对女性形象的价值取向和审美追求,从中我们也可以看到女性的现实社会和文化状况的某些侧面。

Should Children Attend Their Parent's Funerals?

The paper discusses elements of the findings of 'Iceberg', a doctoral study at the University of York addressing many issues of child bereavement through a retrospective study of nearly one hundred individuals who had either experienced the death of a parent when they were at school, or were the surviving parent of such a child. The research revealed issues of lack of control and information for children after a parental death. Forty-seven per cent of those in the study attended the funeral of their parent. There was correlation between the age of children and attendance at the funeral. Of the fifty-three per cent of children not attending, twenty-four per cent of them were forbidden to attend, whilst eleven per cent of them were distracted from attending the funeral, such as being sent to school or a neighbours and being unaware that it was taking place. None of the children attending the funeral reported any negative experiences, and two thirds of them reported it as a positive or helpful event. In contrast, over three-quarters of those not attending later wished that they had. Over a third had feelings of regret, others feeling that they had been excluded from the family at the time of the death, and felt anger, hurt, and frustration. The conclusion was that the best strategy is to give children informed choice about whether or not to attend. If children do attend a negative outcome seems unlikely, but it would be prudent to prepare them as to what to expect at the ceremony.     

普世伦理广告心态刍议

广告的巨大影响使许多事物都带上了重在宣传的“广告心态” ,走出神学院和象牙塔进行普世化的普世伦理也未能免俗。内在逻辑上的填补缺失 ,方法手段上的化繁复为简约 ,社会功能上的灵魂麻醉 ,最终目的上的推销自己的主张 ,作为“沉默的大多数”的普世对象 ,所有这一切都使普世伦理和广告如出一辙 ,而这种将普世伦理等同于广告宣传的做法极易降低人们的思想水平 ,是不可取的。
