Title: The Influence of Social Media on Teenagers' Mental Health: A Cross-sectional Study

Abstract:

The rise of social media has greatly impacted the lives of teenagers, and there is growing concern about its potential effects on mental health. This cross-sectional study aims to investigate the influence of social media on the mental health of teenagers. A sample of 500 teenagers aged 13-19 years old was recruited from various schools in a metropolitan area. The participants completed a self-report questionnaire that assessed their social media usage, mental health symptoms, and perceived social support. The results showed that the majority of teenagers (85%) reported using social media platforms on a daily basis. Among them, 60% reported experiencing symptoms of depression, anxiety, or stress. The study also found a significant negative correlation between social media usage and perceived social support (r = -0.32, p < 0.001). Furthermore, multiple regression analysis revealed that social media usage significantly predicted mental health symptoms (β = 0.21, p < 0.001) after controlling for age, gender, and perceived social support. These findings suggest that excessive social media usage may have detrimental effects on the mental health of teenagers, particularly in terms of increased mental health symptoms and decreased social support. Therefore, it is crucial for parents, educators, and mental health professionals to be aware of the potential risks associated with social media use among teenagers and to develop strategies to promote healthy social media habits.

Keywords: social media, teenagers, mental health, depression, anxiety, stress, social support

Title: The Impact of Exercise on Cognitive Function in Older Adults: A Systematic Review and Meta-analysis

Abstract:

As the global population ages, maintaining cognitive function in older adults has become a significant public health concern. This systematic review and meta-analysis aim to examine the impact of exercise on cognitive function in older adults. A comprehensive search was conducted in electronic databases for randomized controlled trials (RCTs) published between 2010 and 2020. The inclusion criteria included RCTs that assessed the effects of exercise interventions on cognitive function in individuals aged 60 years and above. A total of 20 studies met the inclusion criteria and were included in the meta-analysis. The results indicated that exercise interventions significantly improved overall cognitive function (standardized mean difference = 0.56, 95% CI 0.38-0.75, p < 0.001) compared to control groups. Subgroup analysis revealed that both aerobic exercise and resistance training were effective in improving cognitive function. Additionally, longer intervention durations (>12 weeks) and higher exercise frequencies (>3 sessions per week) were associated with greater cognitive improvements. Sensitivity analysis confirmed the robustness of the findings. This systematic review and meta-analysis provide strong evidence that exercise interventions have a positive impact on cognitive function in older adults. These findings highlight the importance of incorporating regular exercise into the daily lives of older adults to promote healthy cognitive aging.

Keywords: exercise, cognitive function, older adults, systematic review, meta-analysis, aerobic exercise, resistance training

学术论文英文题名和英文摘要的写作 篇三

学术论文英文题名和英文摘要的写作

英文题名和英文摘要是学术类和技术类科技期刊论文的重要组成部分,是国际间传播、学术交流与合作的桥梁和媒介,有其特殊的意义和作用。好的英文题名和英文摘要对于增加期刊和论文的被检索和引用机会、吸引读者、扩大影响起着不可忽视的作用。为了帮助读者撰写论文英文题名和英文摘要,本文总结了英文题名和英文摘要的基本要求及注意事项,以给读者提供参考和指导。

一、论文题名

1.英文题名撰写的基本要求

题名应简明、具体、确切,能概括文章的主旨,符合编制题录、索引和检索的有关原则并有助于选择关键词和分类号。中文题名一般不超过20个汉字,必要时可加副题名。题名中应避免使用非公知公用的缩略语、字符、代号以及结构式和公式。英文题名的首字母及各个实词的首字母应大写。

2.英文题名撰写的注意事项

除了以上基本要求,我们在写英文题名时还应注意以下几个问题。

(1)英文题名的结构。英文题名以短语为主要形式,尤以名词短语最常见,即题名基本由一个或几个名词加上其前置和(或)后置定语构成。短语型题名要确定好中心词,再进行前后修饰,要注意采用正确的单词顺序,形容词应与其所修饰的名词紧密相邻。

(2)英文题名中的冠词有简化的趋势,凡可用可不用的冠词均可不用。英文题名开头第一个字不得用the, and, an和a。

(3)英文题名中的大小写有以下3种格式:全部字母大写;每个词的首字母大写,但3个或4个字母以下的.冠词、连词、介词全部小写;题名第一个词的首字母大写,其余均小写。

(4)中英文题名的一致性。同一篇论文,其英文题名与中文题名内容上应一致,但不等于说词语要一一对应。在许多情况下,个别非实质性的词可以省略或变动。

总之,题名的用词十分重要,它直接关系到读者对文章的取舍态度,务必字字斟酌。

二、论文摘要

1.摘要的定义

摘要又称概要、内容提要。摘要是论文主体的高度浓缩,它应该能提炼论文的主要观点,简明地描述论文的内容和范围,简短地进行概括和总结。摘要能让读者尽快了解论文的主要内容,以补充题名的不足,并为科技情报文献检索数据库的建设和维护提供方便。

2.摘要撰写的基本要求和注意事项

(1)不得简单重复题名中已有的信息,切忌把引言中出现的内容写入摘要,不要照搬论文正文中的小标题或论文结论部分的文字,也不要对论文内容作诠释和评价。

(2)尽量采用文字叙述,不要将文中的数据罗列在摘要中;文字要简洁,应排除本学科领域已成为常识的内容,应删除无意义的或不必要的字眼;内容不宜展开论证说明,不要列举例证,不介绍研究过程。

(3)摘要的内容必须完整,不能把论文中所阐述的主要内容、观点遗漏,应写成一篇可以独立使用的短文。

(4)摘要一般不分段,切忌条列式书写法。陈述要客观,对

(5)用第三人称。建议采用“对……进行了研究”、“报告了……现状”、“进行了……调查”等记述方式标明文献的性质和文献主题,不必使用“本文”、“作者”等作为主语。
