Data associated with students’ social behaviors and identities were collected through feld notes, a questionnaire, and an interview. Norton’s theory of identity and investment served as the basis to analyze the data from a social perspective. Three main fndings emerged from the data: First, EFL learners identifed themselves as high investors and low investors in their learning, depending on their own opinions about the usefulness of English in their lives. Second, power relationships based on domination and oppression reduced productive investment in the classroom. Third, some high investors resisted unfair relationships of power by investing through collaborative learning. Consequently, participants created diverse English learners’ identities (dominant, submissive, resistant, and productive), which inﬂuenced their academic investment negatively or positively.","PeriodicalId":10484,"journal":{"name":"Colombian Applied Linguistics Journal","volume":" ","pages":""},"PeriodicalIF":0.3,"publicationDate":"2019-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47235361","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study was conducted on a group of thirty-one 7th grade students aged between 12 and 13 years and enrolled in a subsidised school in Chile. The convenience sampling method was employed to select the participating students and the participants’ manner of communication was analysed through several English speaking sessions in which they used their smartphone video recording applications. Data collection was undertaken through pre- and post-speaking tasks used in this action research. The collected data were examined using a specific analytic rubric and a focus group interview. Data analysis was accomplished via two techniques: a simple percentage analysis and a thematic examination. The findings revealed an increase in the speaking fluency of the participating students, specifically with regard to the ‘pace’ criterion identified in the analytic rubric used to assess improvement in the speaking performance of students as evidenced by video recordings. Also, the results of the focus group interview conducted with the students evidenced the participants’ positive response to the use of smartphone recording video applications in ameliorating their English communication fluency.","PeriodicalId":10484,"journal":{"name":"Colombian Applied Linguistics Journal","volume":" ","pages":""},"PeriodicalIF":0.3,"publicationDate":"2019-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43735806","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A total of 26 psychology students, aged between 19 and 26 years old, taking English classes for academic purposes, and in their fourth semester, participated in this study. This intervention was implemented for an academic semester and aimed to help learners develop their English reading skills—from literal to critical comprehension of short academic texts— through the use of infographics, which are visual tools that combine texts and graphs to help users communicate information. Teachers used students’ infographics to assess their understanding of short academic texts in English, and they interviewed students to learn their opinions on the intervention. Further, teachers implemented a colour-coding technique in interview transcripts to show relevant patterns in the student opinions. This data analysis indicated that the students clearly understood the ideas from the texts because they were able to go beyond reading to dynamise information in the infographics while using the visual aids as mediators in expressing their ideas. In conclusion, the infographics were beneficial in developing the students’ reading skills. They presented an opportunity for the students to paraphrase main ideas from the texts and represent their understanding of the readings. In addition, this pedagogical intervention was useful for teachers because it enabled them to explore reading comprehension using a new strategy that might be helpful in English classes.","PeriodicalId":10484,"journal":{"name":"Colombian Applied Linguistics Journal","volume":" ","pages":""},"PeriodicalIF":0.3,"publicationDate":"2019-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41849443","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Indoleamine 2,3-dioxygenase (IDO) is another IFNγ inducible gene that has potent immunosuppressive effects. There have been reports of IDO expression in prostate cancer; however, it is unknown whether IDO expression might similarly increase in prostate tumors following T-cell-based immunotherapy.Methods: Blood samples from normal male blood donors (n = 12) and patients with different stages of prostate cancer (n = 89), including patients with metastatic, castration-resistant prostate cancer treated with a DNA vaccine and/or pembrolizumab, were evaluated for IDO activity by kynurenine and tryptophan levels. Metastatic tissue biopsies obtained pre- and post-treatments were evaluated for IDO expression. IDO suppression of vaccine-induced T-cell function was assessed by ELISPOT.Results: Overall, IDO activity was increased in patients with more advanced prostate cancer. This activity, and IDO expression as detected immunohistochemically, increased following treatment with either a DNA vaccine encoding the prostatic acid phosphatase (PAP) tumor antigen or PD-1 blockade with pembrolizumab. Increased IDO activity after treatment was associated with the absence of clinical effect, as assessed by lack of PSA decline following treatment. Increased antigen-specific T-cell response, as measured by IFNγ release, to the vaccine target antigen was detected following in vitro stimulation of peripheral blood cells with 1-methyltryptophan.Conclusions: These findings suggest that IDO expression is a mechanism of immune evasion used by prostate cancer and that future clinical trials using T-cell-based immune strategies might best include IDO inhibition.","PeriodicalId":10484,"journal":{"name":"Colombian Applied Linguistics Journal","volume":"19 1","pages":"1661-1669"},"PeriodicalIF":5.8,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7111534/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90681042","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
