We selected 22 such breast cancer journals written by patients published after 2000 in Japan. The extracted statements related to benefit finding of patients experiencing breast cancer from the 22 journals were subjected to a qualitative analysis, and the following seven benefit finding elements were extracted: “Gratitude toward others”, “Benefits due to cancer”, “Happiness at living a normal life”, “Realization of and satisfaction with my growth”, “Awareness of the meaning of my existence”, “Hopes for life”, and “Willingness to contribute to others”. These benefit findings suggest that these particulars fulfill cultural, practical, spiritual, and social meanings, and lead to self-revaluation in daily life.展开更多

Cognitive abilities, such as selective attention and crystallized as well as fluid intelligence, have been defined as crucial factors for the acquisition of written language skills. However, it is unclear whether these abilities are necessary also for the alphabetization of adults. Before and after a one-year alphabetization course, we compared the attention and intelligence of 47 illiterate individuals to 41 matched literate controls who did not take part in the alphabetization course. Illiterate individuals improved in selective attention and crystallized intelligence from before to after the alphabetization course;however, they did not reach the same level of functioning as literate controls. In addition, the fluid intelligence of illiterates did not improve. More importantly, when controlling for attention improvement, we found that improvement in crystallized intelligence was associated with alphabetization above and beyond the influence of attention. Our results suggest that alphabetization is closely related to improvements in attention and crystallized intelligence. Specifically, socio-cultural, knowledge- specific learning processes improve during the acquisition of written language skills and may not depend on only the enhancement of the ability to attend to relevant stimuli. Alphabetization programs may, therefore, benefit from distinct considerations of attentional, intellectual, and literacy related skill acquisitions.展开更多

Photography is therefore at the heart of the new information system: the application of a new formula, a photographic formula, therefore visual, which is a novelty. The aim of our article is to highlight how the Cameroonian daily press constructs the discursive staging of this visual content. It proposes to examine the ways in which the news image in <i>Cameroon Tribune</i> is constituted in journalistic writing. In this article, we will analyse the photographic content of the daily newspaper <i>Cameroon Tribune</i>. The corpus consists of 1245 photographs from 25 issues published between 21 October and 22 November 2019. The technique used is media content analysis, which allows us to produce exhaustive descriptive statements that meet the criteria of scientific validity and reproducibility. Emancipated from its strict illustrative function, photography in the daily newspaper <i>Cameroon Tribune</i> then becomes fully a means of information and communication, in the same way as text. This translates into the construction of informative sets such as the importance of the surface area of the visual content which gives pride of place to the visual, giving an impression of abundance that is perceptible from the Front Page. One of the important features of the newspaper’s iconography is the great positivity of its images, which reinforces the closeness between the reader and the news. In total, the newspaper highlights photographs of limited informative interest: these are portraits that show the faces of the protagonists of the articles, to the detriment of current events.展开更多

Eighty-two Chinese junior students from two classes were observed in a draft-to-draft writing program.Results included error distribution and WCF's effect on the subjects' writing. Specifically, the number of localerrors dropped more significantly than that of global errors. Both direct feedback (DF) and indirect feedback (IF)worked for local errors, but they did not have noticeable effects on global errors. For some errors as wrong word,DF was almost helpless in eliminating them, but IF worked better since it could engage students in reflecting ontheir own errors. For Chinglish and word order errors, however, IF's role was very limited in revision andcorrection, due to students' inefficient syntactic knowledge. This study indicated that WCF had varying effects fordifferent types of errors and a combination of DF and IF might be more helpful. In addition, positive input andcertain amount of explicit grammar teaching are necessary for long-term improvement of accuracy in writing.展开更多

According to David Kaplan, in face-to-face communication, "I," "here," and "now" refer respectively to the agent, the place, and the time of the context of utterance. In recorded and written messages, however, the identification of pure indexical references is nontrivial, given that there is a gap between the time of utterance and that of interpretation. In the literature, four major views are proposed from a philosophical perspective. While these are theoretically competing, no empirical data or pragmatic analyses have been provided. How is the reference of "now" in written messages interpreted? Which views proposed in the literature are supported empirically? This paper investigates these questions from experimental and pragmatic perspectives.展开更多

This paper aims at providing some references and suggestions on the effective feedback types in EFL writing in China through reviewing the recent ten-year researches on teachers’ written feedback in EFL writing in China from the perspectives of feedback source, content, types and comments, and exploring the future development of the researches from research design, feedback types, and research perspectives and so on.Literature research shows that the answers remain controversial on which kind of feedback source, feedback content, feedback type, and feedback comments are the best to students in EFL writing. However, the supplementary roles of peer feedback and electronic feedback are well recognized; form-focused feedback combined with content-focused feedback is popular with the students; the demand for the degree of feedback directness and feedback comments varies with the level of students. Compared to the past, recent domestic researches on teachers’ feedback are more various in research methods, more diversified in research perspectives and extended more in research content. Future domestic research on teachers’ feedback needs to make efforts on designing the experiment, expanding the feedback content, combining different feedback types and broadening research perspectives in order to further verify the effectiveness of teachers’ written feedback.展开更多

Here we design an 'electrically written and optically read' information storage device employing BiFeO3/A u heterostruetures with strong absorption resonance. The electro- optic effect is the basis for the device design, which arises from the strong absorption resonance in BiFeO3/Au heterostructures and the electrically tunable significant birefringence of the BiFeO3 film. We first construct a sim- ulation calculation of the BiFeO3/Au structure spectrum and identify absorption resonance and electro-optical modulation characteristics. Following a micro scale partition, the surface reflected light intensity of different polarization units is calculated. The results depend on electric polarization states of the BiFeO3 film, thus BiFeO3/Au heterostructures can essentially be designed as a type of electrically written and optically read infor- mation storage device by utilizing the scanning near-field optical microscopy technology based on the conductive silicon cantilever tip with nanofabricated aperture. This work will shed light on information storage technology.展开更多
