哈姆迪·乌鲁卡亚：酸奶界的乔布斯

一款名为乔班尼的希腊酸奶,一夜之间成为了美国街谈巷议的焦点。其迅猛的增长势头,不但使得美国国产酸奶企业评级下调,还引来了各大跨国乳品企业的群起效仿。拜托老爸,我才不想做酸奶1998年的某个下午,哈姆迪·乌鲁卡亚离开土耳其到美同学习经商,已有一年了,这天,他驱车到机场接父亲——那个仍然整天跟酸奶和奶酪打交道的老农场主。坐在机场餐厅共进午餐,老人再一次向他抱怨起美同人的酸奶口味：“糟糕透了,你膨该生产酸奶和奶酪给美国人尝尝,优质的酸奶、奶酪!”在土耳其就一直生产酸奶和奶酪,到美国来我还要做同样的事情吗？”乌鲁卡亚一笑置之。

民主党政府的“农户收入补偿制度”评析——以大米政策为例

民主党在2009年众议院选举中提出"农户收入补偿制度",是其赢得农村选票进而击败自民党的关键因素。本文以大米政策为例,详细阐述了该制度的由来及内容,并对其进行了评析,认为民主党的这一"农户收入补偿制度"带有明显的大众迎合性,但是民主党政府按承诺照办的可行性较低,坐稳政权后以国际贸易自由化压力和提高农业竞争力为理由灵活对待的可能性反而极高。

触摸凝固的永恒——贾克梅蒂艺术中的空间研究

在当代艺术领域中,瑞士艺术家阿尔贝托.贾克梅蒂的艺术地位是不可取代的。他以独一无二的视觉体验开启了具象绘画的新视点。贾克梅蒂的作品总是徘徊在真实与幻境,虚无与存在之间,艰涩深邃。研究其独特的艺术观,应以作品中体现出的内容与组成画面的各种元素为基础来阐释,这样才有可能真正剖析大师在作品中如此表达的实际意图。     

Mechanical tasting: sensory science and the flavorization of food production

The paper narrates the history of “texturometers”, devices that imitate the human biting mechanism and are used by food scientists in experiments on food texture. Two interrelated processes, characteristic of the emergence of industrialized food production in the twentieth century, are examined through this history of mechanical tasting. First, the paper surveys the pervasive project of transforming the phenomenological qualities of flavor and food texture into robust “objective” and “standardized” data. In constructing and using biomimetic texturometers, food sensory scientists attempted to translate texture qualities such as tenderness, crispness, crunch and chewiness into codified properties by producing formal definitions and graphical representations – an example of how the pursuit of objectivity and standardized knowledge coevolved with the rise of mass production and the emergence of sensory sciences. Secondly, the texturometers are related to an overall “flavorization”; that is, a historical process by which the complexes of sensory impressions became increasingly important for the production and consumption of food in late-modern industrialized societies.

Preparation of youth in congregate care for independent living

This paper reports on findings from a qualitative study that focused on the quality and adequacy of preparation of youth in congregate care for independent living. This study, conducted in New York, NY, USA, explored the extent to which youth feel prepared to leave care and the opportunities they are given to participate in planning and decision‐making regarding issues that personally affect their future. Interviews were conducted with professionals and young adults who had exited foster care after placements in congregate care settings. Both professionals and young adults stated concerns about the quality of independent living preparation. Many young adults stated that they were not ready to live independently and expressed concerns about failure of staff to begin preparing youth sufficiently in advance of their discharge dates. Young adults also reported limited opportunities to participate in the planning and decision‐making processes affecting them. Recommendations for improvement of independent living preparation are proposed.     

Social Work Students' Perceived Knowledge of and Preparation for Group-Work Practice

ABSTRACT

The purpose of this study was to identify factors relevant to social work students' perceived knowledge of and preparation for group-work practice. In addition, the experiences of students in the classroom and in the field are discussed in relationship to these variables. Although classroom and field experiences were significant, exposure to group in the field placement was a much stronger predictor of group-work knowledge. Students reported feeling most knowledgeable about the concepts of mutual aid, diversity, group culture, and group phases. Reported gaps in learning were related to research and legal issues associated with group work.

Longitudinal Effects of Economic Preparation and Social Activities on Life and Family Relationship Satisfaction among Retirees

This longitudinal study examined the long‐term effects of economic preparation and social activity on life and family relationship satisfaction among retirees, particularly baby boomers. Data was obtained from the 2009 and 2011 Korean Retirement & Income Panel Study. A fixed effects model was employed to estimate unobservable individual‐specific effects and to control for study participants’ individual characteristics. The results show that both economic preparation and social activities have long‐term effects on baby boomers’ life and family relationship satisfaction. This study reveals that multidimensional aspects of preparation increase the long‐term impact of life satisfaction for retirees.     

大分子偶联剂的制备及其在Nano-SiO2/EP材料中的应用

利用分段加入甲基丙烯酸缩水甘油酯、丙烯酸甲酯、丙烯酸丁酯和γ-甲基丙烯酰氧基丙基三甲氧基硅烷的自由基聚合方法合成了大分子偶联剂———功能性聚丙烯酸酯,并对聚合物的结构进行了表征。将大分子偶联剂———功能性聚丙烯酸酯应用到纳米二氧化硅改性环氧树脂固化物体系中,并对固化物的热性能及断裂横截面形貌进行研究。结果显示：与单纯的纳米二氧化硅改性环氧树脂固化物相比,加入大分子偶联剂———功能性聚丙烯酸酯后,固化物的玻璃化转变温度变化较小,起始热分解温度降低,断裂横截面的形貌呈现明显的韧性断裂,环氧树脂固化物的韧性得到明显提高。
