文化研究视野下的成人消费教育研究     

吕关心 《湖北大学成人教育学院学报》2013,(4):53-56

成人教育是在消费资本主义的环境中存在的。传统的成人消费教育普遍关注消费技巧,因而被置于社会、政治和文化领域之外。从文化研究的视野解读消费教育,可以发现,消费教育是一种政治领域。不同内容消费教育下的成人会对消费文化产生不同的态度。从文化研究的视野审视消费教育,为丰富成人教育的内涵和功能提供了可能。  相似文献   

我国成人学习基本状况调查     

何光全 《现代远程教育研究》2013,(6):58-69

成人学习是一个涉及心理、教育、文化、社会、政治、经济等诸多因素的复杂问题,对成人学习基本信息的采集,是科学规划与实施全民学习项目的前提。我国大陆（不包括港澳台地区）16岁及以上各类成人群体的随机调查显示：我国成人学习的范围和领域十分广泛,学习需求涵盖工作、职业、自我发展以及正在或者将要扮演的社会角色等诸多方面。工学矛盾是影响我国成人学习参与的首要因素,其次是社会角色及其承担的相应责任,再次是当地能否提供适当的学习机会、学习信息、学习时间和地点。学习费用、性别、年龄、地理环境’与地区经济社会发展的不平衡,也是影响成人学习参与的重要因素。总之,我国继续教育和终身学习条件及环境营造等方面还存在诸多不足,成人学习支持服务体系建设情况不容乐观。为了进一步改进成人学习规划与实施工作,相关管理部门、用人单位和教育培翻I机构,应组建或委托专门机构,对我国成人学习状况相关问题展开定期调查;同时,充分考量性别、年龄、地理环境与地区经济社会发展的差异,重视成人工学矛盾和社会角色,兼顾成人多方面学习需求,积极营造有利于成人深度参与的学习环境,建立健全成人学习费用分担机制和成人学习支持服务体系,进一步提高各行各业从业人员继续教育和学习的参与率。  相似文献

Impact of age on host responses to diet-induced obesity:Development of joint damage and metabolic set points     

Kelsey H.Collins  Graham Z.MacDonald  David A.Hart  Ruth A.Seerattan  Jaqueline L.Rios  Raylene A.Reimer  Walter Herzog 《运动与健康科学(英文)》2020,9(2):132-139,197

Background:Osteoarthritis is one of the leading causes of pain and disability worldwide,and a large percentage of patients with osteoarthritis are individuals who are also obese.In recent years,a series of animal models have demonstrated that obesity-inducing diets can result in synovial joint damage(both with and without the superimposition of trauma),which may be related to changes in percentage of body fat and a series of low-level systemic inflammatory mediators.Of note,there is a disparity between whether the dietary challenges commence at weaning,representing a weanling onset,or at skeletal maturity,representing an adult onset of obesity.We wished to evaluate the effect ofthe dietary exposure time and the age at which animals are exposed to a high-fat and high-sucrose(HFS) diet to determine whether these factors may result in disparate outcomes,as there is evidence suggesting that these factors result in differential metabolic disturbances.Based on dietary exposure time,we hypothesized that rats fed an HFS diet for 14 weeks from weaning(HFS Weanling) would demonstrate an increase in knee joint damage scores,whereas rats exposed to the HFS diet for 4 weeks,starting at 12 weeks of age(HFS Adult) and rats exposed to a standard chow diet(Chow)would not display an increase in knee joint damage scores.Methods:Male Sprague-Dawley rats were fed either an HFS diet for 14 weeks from weaning(HFS Weanling) or an HFS diet for 4 weeks,starting at 12 weeks of age(HFS Adult).At sacrifice,joints were scored using the modified Mankin Criteria,and serum was analyzed for a defined subset of inflammatory markers(Interleukin-6,leptin,monocyte chemoattractant protein-1,and tumor necrosis factorα).Results:When the HFS Weanling and HFS Adult groups were compared,both groups had a similar percent of body fat,although the HFS Weanling group had a significantly greater body mass than the HFS Adult group.The HFS Weanling and HFS Adult animals had a significant increase in body mass and percentage of body fat when compared to the Chow group.Although knee joint damage scores were low in all 3 groups,we found,contrary to our hypothesis,that the HFS Adult group had statistically significant greater knee joint damage scores than the Chow and HFS Weanling groups.Furthermore,we observed that the HFS Weanling group did not have significant differences in knee joint damage scores relative to the Chow group.Conclusion:These findings indicate that the HFS Weanling animals were better able to cope with the dietary challenge of an HFS diet than the HFS Adult group.Interestingly,when assessing various serum proinflammatory markers,no significant differences were detected between the HTS Adult and HFS Weanling groups.Although details regarding the mechanisms underlying an increase in knee joint damage scores in the HFS Adult group remain to be elucidated,these findings indicate that dietary exposure time maybe less important than the age at which an HFS diet is introduced.Moreover,increases in serum proinflammatory mediators do not appear to be directly linked to knee joint damage scores in the HFS Weanling group animals but may be partially responsible for the observed knee joint damage in the adults over the very short time of exposure to the HFS diet.  相似文献   

Applying user analytics to uses and effects of social media in China     

Jonathan J. H. Zhu  Yixin Zhou  Lu Guan  Lei Hou  Anqi Shen  Heng Lu 《亚洲交流杂志》2019,29(3):291-306

ABSTRACT

We introduce what user analytics can do in the first half of the paper and then illustrate how to do user analytics in the second half. In the current context, user analytics refers to a set of diverse communication research methods on uses and effects of social media. User analytics has evolved from TV ratings research to online user research. The history illustrates what data sources, measures, and analyses can be used for what types of research questions under user analytics. We discuss the similarities of and differences between user analytics and other methods of computational communication research (e.g. content mining and online experiments), and compare the strengths and weaknesses of user analytics with traditional quantitative methods (e.g. survey). Finally, we present an application study of Chinese bloggers to demonstrate how to employ user analytics methods to study the production, consumption, and effects of user-generated content.  相似文献   

Effects of purposeful soccer heading on circulating small extracellular vesicle concentration and cargo

BackgroundConsidering the potential cumulative effects of repetitive head impact (HI) exposure, we need sensitive biomarkers to track short- and long-term effects. Circulating small extracellular vesicles (sEVs) (<200 nm) traffic biological molecules throughout the body and may have diagnostic value as biomarkers for disease. The purpose of this study was to identify the microRNA (miRNA) profile in circulating sEVs derived from human plasma following repetitive HI exposure.MethodsHealthy adult (aged 18–35 years) soccer players were randomly assigned to one of 3 groups: the HI group performed 10 standing headers, the leg impact group performed 10 soccer ball trapping maneuvers over 10 min, and the control group did not participate in any soccer drills. Plasma was collected before testing and 24 h afterward, and sEVs were isolated and characterized via nanoparticle tracking analysis. Next-generation sequencing was utilized to identify candidate miRNAs isolated from sEVs, and candidate microRNAs were analyzed via quantitative polymerase chain reaction. In silico target prediction was performed using TargetScan (Version 7.0; targetscan.org) and miRWalk (http://mirwalk.umm.uni-heidelberg.de/) programs, and target validation was performed using luciferase reporter vectors with a miR-7844-5p mimic in human embryonic kidney (HEK) 293T/17 cells.ResultsPlasma sEV concentration and size were not affected across time and group following repetitive HI exposure. After 24 h, the HI read count from next-generation sequencing showed a 4-fold or greater increase in miR-92b-5p, miR-423-5p, and miR-24-3p and a 3-fold or greater decrease in miR-7844-5p, miR-144-5p, miR-221-5p, and miR-22-3p. Analysis of quantitative polymerase chain reaction revealed that leg impact did not alter the candidate miRNA levels. To our knowledge, miR-7844-5p is a previously unknown miRNA. We identified 8 miR-7844-5p mRNA targets: protein phosphatase 1 regulatory inhibitor subunit 1B (PPP1R1B), LIM and senescent cell antigen-like domains 1 (LIMS1), autophagy-related 12 (ATG12), microtubule-associated protein 1 light chain 3 beta (MAP1LC3B), integrin subunit alpha-1 (ITGA1), mitogen-activated protein kinase 1 (MAPK1), glycogen synthase kinase 3β (GSK3β), and mitogen-activated protein kinase 8 (MAPK8).ConclusionCollectively, these data indicate repetitive HI exposure alters plasma sEV miRNA content, but not sEV size or number. Furthermore, for the first time we demonstrate that previously unknown miR-7844-5p targets mRNAs known to be involved in mitochondrial apoptosis, autophagy regulation, mood disorders, and neurodegenerative disease.  相似文献   

The influence of childhood polyvictimization on disordered eating symptoms in emerging adulthood     

《Child abuse & neglect》2017

Children who endure multiple victimization experiences, or “polyvictims," are vulnerable to maladaptive outcomes. Yet, little research exists evaluating the relationship between childhood polyvictimization and disordered eating symptoms (DES) in emerging adulthood. The current study examines the relationship between childhood polyvictimization and DES in emerging adults. Data were collected from 288 participants across two universities using online self-report measures. Hierarchical regression analyses revealed a significant positive relationship between number of childhood victimization experiences and DES in young adulthood (ß = 0.14; p = 0.016). Female participants were more likely to demonstrate DES (ß = 0.14; p = 0.008). Further, high levels of emotion dysregulation during young adulthood were associated with more DES (ß = 0.33; p < 0.001). Findings suggest that exposure to victimization experiences in childhood increases individuals’ risk for exhibiting DES in young adulthood. Results also highlight the strong relationship between individuals’ emotion regulation abilities and the presence of DES. Findings align with the theory that children who have endured high levels of victimization often feel overwhelmed by their emotions and circumstances, demonstrate emotion regulation difficulties, and may rely on maladaptive coping strategies, including disordered eating, to manage adversities. Study results emphasize the importance of considering victimization history when working with emerging adults displaying disordered eating symptomatology.  相似文献
