The addition of spices and herbs to vegetables in the National School Lunch Program increased vegetable intake at an urban,economically-underserved,and predominantly African-American high school

Vegetable intake is far below recommendations among African-American adolescents living in economically-underserved urban areas. While the National School Lunch Program (NSLP) helps overcome access barriers, vegetable intake remains challenging and novel interventions are required. A two-year, multi-phase, school-based intervention was conducted at an urban, economically-underserved, and predominantly African-American high school in Baltimore, Maryland to determine whether stakeholder-informed addition of spices and herbs to NSLP vegetables would increase intake. The stakeholder engagement phase included assessment of NSLP vegetable attitudes/preferences among 43 school stakeholders and subsequent student sensory testing. The second phase was conducted in the school cafeteria and consisted of eight weeks comparing student intake of typical vegetable recipes versus otherwise-identical recipes with spices and herbs. 4570 student lunch plates were included in the vegetable intake comparison. Vegetable intake was measured by lunch tray plate waste. Willingness to try vegetables was assessed by the difference between plate waste and estimated mean vegetable served weight. Intake of typical vegetable recipes and vegetable recipes with spices and herbs was compared with student’s t-test. Chi-square test was used to compare willingness to try vegetables. Total vegetable intake was 18.2% higher (8.22 g per meal, p < 0.0001) with spices and herbs than with typical recipes. There were no differences in trying vegetables with spices and herbs, although student-led advocacy was associated with increased trying vegetables with spices and herbs (78.8% with advocacy, 67.5% without advocacy, p < 0.0001). The addition of spices and herbs to vegetables in the NSLP was feasible and associated with small increases in vegetable intake at an urban, economically-underserved, and predominantly African-American high school.     

Investigation of bacterial and fungal communities in indoor and outdoor air of elementary school classrooms by 16S rRNA gene and ITS region sequencing

The advent of high-throughput sequencing methods allowed researchers to fully characterize microbial community in environmental samples, which is crucial to better understand their health effects upon exposures. In our study, we investigated bacterial and fungal community in indoor and outdoor air of nine classrooms in three elementary schools in Seoul, Korea. The extracted bacterial 16S rRNA gene and fungal ITS regions were sequenced, and their taxa were identified. Quantitative polymerase chain reaction for total bacteria DNA was also performed. The bacterial community was richer in outdoor air than classroom air, whereas fungal diversity was similar indoors and outdoors. Bacteria such as Enhydrobacter, Micrococcus, and Staphylococcus that are generally found in human skin, mucous membrane, and intestine were found in great abundance. For fungi, Cladosporium, Clitocybe, and Daedaleopsis were the most abundant genera in classroom air and mostly related to outdoor plants. Bacterial community composition in classroom air was similar among all classrooms but differed from that in outdoor air. However, indoor and outdoor fungal community compositions were similar for the same school but different among schools. Our study indicated the main source of airborne bacteria in classrooms was likely human occupants; however, classroom airborne fungi most likely originated from outdoors.

Promoting or prohibiting: Understanding the influence of social media on international students’ acculturation process,coping strategies,and psychological consequences

Although the unprecedented prevalence of social media has infiltrated into international students’ daily trajectories and become an indispensable component of their intercultural communication, yet surprisingly few attempts have been implemented to systematically unpack how the innovative technology could play a role in these sojourners’ acculturation experiences and the consequences of migration and cross-cultural adaption. In order to address such research gap, the objective of this present article is to provide a review of academic, peer-reviewed journal studies that examined the potential effect of social media engagement on international university students’ acculturation process, coping strategies, and psychological adjustments during the period from 2010 to 2019. Moreover, building upon conceptualizations from new media and transcultural research literature, a conceptual framework was developed to classify the relevant studies for further analysis. Overall, these theories and studies synthesized in this paper emphasize the vital role of social media in the acculturation, coping behaviors and mental health for ethnic minorities in the host country. Additionally, certain dimensions of attitudes and behaviors through social media could exert the important influence on the psychological adaption. Therefore, conclusions of the research may assist to further inform practitioners who may encounter newcomers’ experiencing intercultural adjustments and psychological issues in the digital media age. Furthermore, this current review may also help educators determine certain barriers that have not been resolved in campus tactics which may influence the acculturation of sojourning populations.     

北京中学生营养知识现况及其影响因素分析

目的:了解北京市中学生营养知识掌握现况并探讨影响因素。方法:采用整群典型抽样,抽取北京核心城区和郊县城区数所代表性中学学生,开展现场问卷调查。结果:北京市6所中学1192名学生参与问卷调查,其中初中生789人、高中生392人,男生600人(50.80%)、女生581人(49.20%),平均年龄13.72±1.58岁(最小11岁、最大19岁);中学生营养知识平均得分为59.37,初中生59.78,高中生58.53;女生61.08,男生57.71;学生对不同类别营养知识的知晓率差异显著(P<0.05);女性学生、与父母同住、父母学历高与学生营养知识得分存在正相关关系。结论:北京市中学生营养知识得分处于不及格水平,对不同知识类别的知晓度差异显著,学生在初高中阶段学习和掌握营养知识缺乏系统连贯性。学校课程设置、年级、性别、父母学历、居住状况等影响学生营养知识掌握状况。学校应考虑家庭和社会参与,衔接初高中阶段课程教学,加强系统、综合和连贯性的学生营养教育。     

基于学生群体心理测试系统的设计

心理测试的根本目的是为了让人们在测试过程中，产生某些特定行为，即个体对测试题目的反应，并根据这些行为反应来推论其相应的心理特性。在一定程度上帮助我们了解人类的心理活动，并从中得到帮助。因此，本文对基于学生群体心理测试系统的设计进行深入研究。     

Facebook use and academic performance among college students: A mixed-methods study with a multi-ethnic sample

This paper uses a mixed-methods approach to examine the relation between online academic disclosure and academic performance. A multi-ethnic sample of college students (N = 261; male = 66; female = 195; M age ≈ 22 years) responded to open-ended questions about their Facebook use. Thematic analysis revealed that over 14% of the Facebook wall posts/status updates (N = 714) contained academic themes; positive states were more frequent than negative and neutral states and students with lower GPAs expressed negative states more often. A path analysis suggested that academic performance may determine college students’ Facebook use, rather than the reverse. Implications for student support services are discussed.     

Learning effectiveness of applying automated music composition software in the high grades of elementary school

The paper is mainly to explore the automated music composition experiences for the students in the high grades of elementary school who are unfamiliar with the professional music theory. The proposed Automated Composition for Music Education (ACME) software was developed to help the students to compose the rhythm and melody themselves, while chord configuration and arrangement are automatically generated. Subsequently, sixth-year students of a non-experimental school were recruited to use the software for the completion of its development. Analysis of learning effectiveness at the reaction level, analysis of learning-level learning effectiveness, correlation analysis of the reaction- and learning-levels learning effectiveness has been performed with a significant result. The correlations between each component of learning effectiveness at the reaction and learning levels were also found. Finally the students in the experimental group using the ACME teaching materials showed a better learning effectiveness at both reaction level and learning level, than those of the students in the comparison group.
