One of the focuses of SFG is register, which is composed of field, tenor and mode. Halliday particularly developed these three main parameters, which are useful for characterizing the nature of the social transaction of the participants. In this essay, the method of tenor is used for analyzing Barack Obama's speech on Boston Marathon bombing event to explore how Obama trans fers his ideas to audience in order to achieve his goals.展开更多

METHODS Six outreach sessions were held in various community venues in the Greater Boston Area. Verbal consent was obtained from participants prior to starting each session. Each session included a pre-session questionnaire, followed by a teaching session, and then a post-session questionnaire. In person interpreters were present for translation during the teaching session and assistance for questionnaire completion when needed. The questions were developed based on the HBV clinical experience of physicians who serve largely immigrant populations. Questionnaires included Likerttype scale, open-ended, and true-false questions. All results were anonymous. RESULTS One hundred and one people participated in this study. Participants were 30% male with ages ranging from 19 to 87 years. The study population included immigrants from 21 countries, as well as seven United States-born participants. The greatest numbers of participants were from Somalia(44%), Morocco(10%), and Cameroon(8%). Pre session questionnaires revealed that 42% of participants were unaware that HBV can cause cancer, and 50% were unaware that therapies for HBV exist. Our brief teaching intervention led to improved scores on post session questionnaires. For example, at baseline, 58% of participants responded correctly to the question "HBV infection can cause scarring of the liver and liver cancer", whereas 79% of participants responded correctly after the teaching session(P = 0.01). Furthermore, the mean of total correct answers in the true or false portion of the questionnaire increased from 5.5 to 7.6(P < 0.001).CONCLUSION A teaching session targeting Boston Immigrants atrisk for HBV helped improve scores on HBV knowledge questionnaires. Outreach may empower at-risk patients to pro-actively seek HBV care.展开更多

Moreover, socioeconomic and demographic factors such as poverty and race/ethnicity may contribute to a difference in treatment setting choice as well as a delay in care seeking. In an urban metropolitan area such as Boston, the overall gonorrhea and chlamydia rates are higher than national rates, and such differences are even more marked in certain neighborhoods with greater proportions of individuals who are impoverished, young, and of color. Using a retrospective analysis of city wide data, we highlight the effects of socioeconomic and demographic variables on urban STI prevalence. High poverty rates, race/ethnicity and younger adult populations are linked to disproportionately high STI rates. Interestingly, STI rates do not appear to be influenced by the universal health care coverage offered to the whole Massachusetts’ resident populations. We examine the effects of these variables in Boston neighborhoods in conjunction to STI rates and hypothesize that the observed rates are underestimates of the true prevalence of infection. Future studies will investigate how these same socioeconomic and demographic factors influence which treatment settings are chosen and subsequently lead to a delay in treatment.展开更多
