USING A GENRE-BASED APPROACH TO IMPROVE THE ENGLISH WRITING COMPETENCE OF VIIIA STUDENTS OF SMPN 3 METRO LAMPUNG IN THE ACADEMIC YEAR 2011/2012
This research is a collaborative classroom action research, and the subject
is VIIIA students of SMPN 3 Metro–Lampung in the academic year 2011/2012
and English teacher who teaches the eight grade of SMPN 3 Metro Lampung. The
method of Kemmis & McTaggart was used in this research, consisting four steps:
(1) planning, which prepared components of the cycle in genre-based approach
including building knowledge of the field, modeling of text, joint construction of
text, and independent construction of text; (2) action, which was the
implementation of each cycle in the genre-based approach; (3) observation,
observing which implemented the genre-based approach; and (4) reflection,
which was a discussion between the researcher and collaborator about the findings
in the observation and action phases. The research instruments were students
observation guide, field note guide, and writing assessment guide. The data were
qualitative and quantitative. The qualitative data were obtained from the results of
classroom observation and field notes, and the quantitative data were the students’
pretest scores, scores in the independent construction of text in each cycle, and
posttest scores. The reliability of the data was obtained by using the triangulation
technique which combined the result of the observation, field note, and the result
of the students’ writing.
The result of the research shows that the improvement was achieved in
every cycle. At the building knowledge of the field phase, the students
competence in expressing vocabulary improved, at modeling of text phase, the
students were able to understand the teachers’ explanation about genre, at the joint
construction of text phase, the students were able to interact with their peers, and
at the independent construction of text phase, the students were able to compose a
text without the teacher’s guide and friends’ help. The result of the improvement
can be seen from the comparation of the pretest result, each cycle result, and
posttest result. The mean score of the students pretest result is 55.05, the result of
the first cycle is 70.08, and the second cycle is 74.63, while the posttest result is
76.1. From those results, it can be concluded that the genre-based approach can
improve the students’ writing competence.

A grammar for a text based music scoring program
The grammar for a text-based music scoring software package and a short example is presented. The computer program developed using this language (available from the author's website) will form the basis for future research into a variety of different input methods for creating music scores
Cognitive support for older people from multimedia options
If older users of multimedia displays could select among presentation options, would they choose display combinations that supported their performance? After three short touch-screen tasks which measured the perceptual and cognitive abilities of 50 older adults, they answered questions about a route on an online map that could be accompanied by written and/or spoken text. Half the participants saw animated routes; and they were less accurate answering questions than those who saw static routes but this did not affect people’s multimedia choices which, although diverse, were systematic. Spoken text was more often selected by people who had lower scores on the spatial working memory task, than by the older adults with higher scores. This suggests that older people with cognitive limitations recognise ways in which multimedia information can be supportive
Comparing the use of edited and unedited text in parser self-training
We compare the use of edited text in the form of newswire and unedited text in the form of discussion forum posts as sources for training material in a self-training experiment involving the Brown reranking parser and a test set of sentences from an online sports discussion forum. We find that grammars induced from the two automatically parsed corpora achieve similar Parseval f-scores, with the grammars induced from the discussion forum material being slightly superior. An error analysis reveals that the two types of grammars do behave differently
The SLS-Berlin: Validation of a German Computer-Based Screening Test to Measure Reading Proficiency in Early and Late Adulthood
Reading proficiency, i.e., successfully integrating early word-based information and utilizing this information in later processes of sentence and text comprehension, and its assessment is subject to extensive research. However, screening tests for German adults across the life span are basically non-existent. Therefore, the present article introduces a standardized computerized sentence-based screening measure for German adult readers to assess reading proficiency including norm data from 2,148 participants covering an age range from 16 to 88 years. The test was developed in accordance with the children’s version of the Salzburger LeseScreening (SLS, Wimmer and Mayringer, 2014). The SLS-Berlin has a high reliability and can easily be implemented in any research setting using German language. We present a detailed description of the test and report the distribution of SLS-Berlin scores for the norm sample as well as for two subsamples of younger (below 60 years) and older adults (60 and older). For all three samples, we conducted regression analyses to investigate the relationship between sentence characteristics and SLS-Berlin scores. In a second validation study, SLS-Berlin scores were compared with two (pseudo)word reading tests, a test measuring attention and processing speed and eye-movements recorded during expository text reading. Our results confirm the SLS-Berlin’s sensitivity to capture early word decoding and later text related comprehension processes. The test distinguished very well between skilled and less skilled readers and also within less skilled readers and is therefore a powerful and efficient screening test for German adults to assess interindividual levels of reading proficiency
Comparing computer-generated and pathologist-generated tumour segmentations for immunohistochemical scoring of breast tissue microarrays
BACKGROUND: Tissue microarrays (TMAs) have become a valuable resource for biomarker expression in translational research. Immunohistochemical (IHC) assessment of TMAs is the principal method for analysing large numbers of patient samples, but manual IHC assessment of TMAs remains a challenging and laborious task. With advances in image analysis, computer-generated analyses of TMAs have the potential to lessen the burden of expert pathologist review. METHODS: In current commercial software computerised oestrogen receptor (ER) scoring relies on tumour localisation in the form of hand-drawn annotations. In this study, tumour localisation for ER scoring was evaluated comparing computer-generated segmentation masks with those of two specialist breast pathologists. Automatically and manually obtained segmentation masks were used to obtain IHC scores for thirty-two ER-stained invasive breast cancer TMA samples using FDA-approved IHC scoring software. RESULTS: Although pixel-level comparisons showed lower agreement between automated and manual segmentation masks (κ=0.81) than between pathologists' masks (κ=0.91), this had little impact on computed IHC scores (Allred; [Image: see text]=0.91, Quickscore; [Image: see text]=0.92). CONCLUSIONS: The proposed automated system provides consistent measurements thus ensuring standardisation, and shows promise for increasing IHC analysis of nuclear staining in TMAs from large clinical trials
