论思想政治教育价值的关系结构

当前 ,在关于思想政治教育价值的中坚核心之一———思想政治教育价值结构的研究中 ,比较缺乏对思想政治教育价值的关系结构的研究 ,即从思想政治教育价值的相关实体中去发现价值生成的一般机理 ,寻求思想政治教育价值何以可能和以何可能的缘起。从一般意义上说 ,思想政治教育价值是由社会和人对思想政治教育的需要程度和思想政治教育在多大程度上能满足社会进步和人的发展的需要决定的 ,而思想政治教育价值关系结构的研究正在于以思想政治教育的价值主体为尺度 ,从价值客体中去发现价值、揭示价值、最终实现价值。     

The Ethnicity of Adolescent Research

The study of adolescence may have come of age, but it remains debatable whether research appropriately considers the ethnic diversity of adolescence. Given a heightened interest in supporting a more inclusive approach to adolescent research, this study takes stock of how seriously we actually are pursuing a more inclusive study of adolescence. To do so, this study examines the extent to which six leading journals dedicated to the study of adolescence publish articles that include ethnic participants, report the nature of that inclusion, and present findings that consider the ethnic dimensions of their samples. Although results reveal some diversity among journals, trends do emerge. For example, the study of adolescence is quite international: overall, more than 40% of 1283 empirical articles (published from 2000 to and including 2006) report findings from non-U.S. samples. If we remove international studies from our analyses, we find that the vast majority of studies (93%) describe the ethnic composition of their samples. That finding diverges considerably from reports from other fields of research. Also unlike other fields of research, studies from journals on adolescence do tend to include ethnic groups. The majority (68%) of articles actually do not have samples with a majority of participants from European American groups. Over 40% of articles present empirical analyses relating to identified ethnic groups, and at least 19% present findings that focus on one ethnic group (rather than comparing one to another). We do, however, find relatively ignored groups (such as Native and Asian Americans) and a tendency to lump diverse groups into five dominant ethnic groups or into “other” groups. We place these findings in the context of research on adolescence and explore their significance. Roger J.R. Levesque is Professor of Criminal Justice, Indiana University.

浅谈社会主义和谐社会的科学内涵

中国共产党多次提出了“构建社会主义和谐社会”这一重大论题。构建社会主义和谐社会,对于巩固党的执政地位,推进社会主义事业,具有十分重大的理论和实践意义。社会主义和谐社会包括人与自然的和谐、人与社会的和谐、社会阶层之间的和谐等几方面内容。     

The Image is the Message: Instagram Marketing and the 2016 Presidential Primary Season

The 2016 presidential primary candidates expanded their social media marketing campaigns to include the image- and video-centered social network platform Instagram. To explore the role that images play in framing political character development and to identify which images received higher levels of engagement, content analyses were performed on the top seven primary candidates’ Instagram accounts. Results indicate that candidates most frequently employ the ideal candidate frame in their images, which also garnered the highest number of user likes and comments. Results also reveal that among Instagram image attributes, candidates frequently and successfully used text within their images, but filters were inconsistently applied across the candidates.     

The Symbolic Construction of Rival Nations: Radio Japan's Coverage of U.S.-Japanese Trade Disputes

Although there is an extensive research literature on the ideological uses of news particularly during times of war there has been little investigation of how media present news in support of their nations' position in international economic conflicts This study analyzes the newscasts of Radio Japan during a period of major trade disputes between Japan and the United States It identi fies the way in which a clear and serviceable image of an international trade rival can be constructed as a cumulative product over an extended period of newscasts     

不同加工方式亳白芍的高效液相指纹图谱及多成分含量比较

目的 评价不同加工方式亳白芍饮片质量,验证亳白芍产地加工与炮制一体化工艺应用的可行性。方法 采用高效液相色谱法建立不同加工方式亳白芍饮片标准煎液的指纹图谱,同时对没食子酸等7种成分含量进行测定,并以指纹图谱共有峰相对峰面积对所有样品进行聚类分析。结果 亳白芍趁鲜片标准煎液指纹图谱相似度较亳白芍生斜片标准煎液相似度高;不同加工方式白芍饮片标准煎液中没食子酸等7种成分含量有一定差异;聚类分析结果将白芍趁鲜片与白芍传统片聚为一类,而白芍生斜片自成一类。结论 产地加工与炮制一体化加工的亳白芍趁鲜片质量与传统片差异较小,可与传统片一并应用,生斜片质量差异略大,能否作为白芍饮片在临床进行应用还需进一步研究。     

五叶木通藤茎三萜皂苷类成分分布规律研究

目的 探究五叶木通藤茎中三萜皂苷类成分的分布积累规律,为进一步研究五叶木通提供依据。方法 采用植物解剖学和组织化学定位方法,对五叶木通藤茎中三萜皂苷类成分进行显色反应;以木通苯乙醇苷B、齐墩果酸、常春藤皂苷元作为活性成分指标,采用高效液相色谱法测定五叶木通不同组织、不同直径中3种活性成分含量。结果 五叶木通藤茎的次生维管组织所占比例与直径成正比,各组织中均有三萜皂苷类成分分布,活性成分在直径小于0.9 cm的藤茎中分布较多,主要集中在次生木质部、皮层及次生韧皮部。结论 五叶木通藤茎中三萜皂苷类成分的分布具有一定规律,可作为五叶木通质量评价的依据。
