2020年3月18日,当美国和加拿大边境所有非必要交通因为新冠疫情而中断时,明尼苏达州西北角(也称为西北角镇)1000万美元的经济产业也画上了休止符。位于美国本土48个州最北端的西北角镇,是历史偶然因素和地理错觉的产物。东面的伍兹湖以及加拿大马尼托巴省把这里与明尼苏达州的其他地区分隔开来。

Perceptions and receipt of Cancer Screening among African Americans: A Community Networks Program Project

Open Journal of Epidemiology 2016年第4期6卷 256-270页

Objective: Minority groups constitute one of the nation’s highest cancer risk groups. Historically, these groups have not been adequately informed about cancer, its prevention and/or treatment. The purpose of this study was to examine participants’ receipt of cancer screening and to explore perceptions of barriers to and facilitators of cancer screening. Methods: A two-part study design consisting of a survey and focus group was conducted among African Americans residents of neighborhoods geographically defined as low-income areas of Chattanooga, Memphis, and Nashville in the state of Tennessee. The survey was administered to 1071 participants, and 12 focus groups were conducted with a total of 112 participants, with both sets of participants being residents of similarly defined underserved communities served by the community health centers. results: Overall, 51% of surveyed respondents were females;the majority (75%) had a yearly income of less than $25,000;and 67% reported 12 years of education or less. Most surveyed respondents had a family history of cancer. More than 30% and 64% of male respondents over 50 years old did not receive prostate cancer and colorectal cancer screening, respectively;58% of women 50 years and older were not screened for colorectal cancer;28% of women over 40 years old did not receive breast cancer screening. Barriers to cancer screening included: lack of information about cancer screening and treatments, cost of cancer treatment and fear. The need for more information about cancer and cancer treatment, as well as the involvement of churches to increase cancer screening awareness was identified as facilitators. Conclusion: This study provides information into the structural and psychological barriers in cancer screening. It describes the self-reported prevalence/frequency of screening among men and women in our target population, and the associated facilitators to screening.

resistance of Nanoclay reinforced Epoxy Composites to Hyperthermal Atomic Oxygen Attack

Due to outstanding mechanical properties, heat resistance, and relatively facile production,nanoclay reinforced epoxy composites(NCrE composites) have been suggested as candidate materials for use on external surfaces of spacecraft residing in the low Earth orbit(LEO) environment. The resistance of the NCrE composites to bombardment by atomic oxygen(AO), a dominant component of the LEO environment, has been investigated. Four types of samples were used in this study. They were pure epoxy(0 wt% nanoclay content), and NCrE composites with different loadings of nanoclay—1 wt%, 2 wt%, and 4 wt%. Etch depths decreased with increasing nanoclay content, and for the 4 wt% samples it ranged from 28% to 37% compared to that of pure epoxy. X-ray photoelectron spectroscopy(XPS) indicates that after AO bombardment, relative area of C-C/C-H peak decreased,while the area of the C-O, ketones peaks increased, and the oxidation degree of surfaces increased. New carbon-related component carbonates were detected on nanoclay containing composite surfaces. Scanning electron microscopy indicates that aggregates formed on nanoclay-containing surfaces after AO bombardment. The sizes and densities of aggregates increased with nanoclay content. The combined erosion depths, XPS and SEM results indicate that although all the studied surfaces got eroded and oxidized after AO bombardment,the nanoclay containing composites showed better AO resistance compared to pure epoxy,because the produced aggregates on surface potentially act as a physical "shield", effectively retarding parts of the surface from further AO etching.

教学促进与教师发展中心如雨后春笋一般在各大高校建立并发展,但中国在教师发展中心的建设上还存在一些亟待解决的问题。通过海外访谈,美国塔夫茨大学教师教学发展中心在人员专业化、项目专业化、管理专业化和细节专业化等方面的举措,值得我国教师教育领域加以学习和借鉴。研究认为,我国的教师发展中心建设应当以理念专业化为核心,以此加强其它方面专业化的建设。
