THE EFFECT OF SELF-EDITING ON WRITING SKILL OF TWELFTH GRADE STUDENTS OF SMAN 1 LUBUKLINGGAU
Authors: Riansih Rismar
Published: February 2018

Self-editing has been considered an important part of writing process that helps improving writing ability and yet become a better writer. This is because by having self-editing, the students are able to recognize their own errors in their composition. Therefore, this current study was conducted to investigate the effect of self-editing on writing skill of twelfth grade students of SMAN 1 Lubuklinggau. The subject of this study consisted of 34 students of grade XII IPA 3. It was found that after experiencing the writing instruction with self-editing, the students� writing skill improved significantly. The students have been very enthusiastic towards the teaching technique. Their score in writing increased from pre-test to the end of cycle II. �The result of pre-test showed that the average was 68. From 34 students in the class, only 7 students got the score�� above 79 and 27 students got the score bellow 79. In addition, in cycle I, the students who got the score above Minimum Mastery Criteria were 12 or 35, 29% and those who got below the Minimum Mastery Criteria that were 22 or 69, 71%.� The average was 75. Finally, in cycle II, the students who got score above Minimum Mastery Criteria were 30 or 88. 24% and those who got below Minimum Mastery Criteria were 4 or 11. 76%.� The average score was 81.32. Hence, it can be concluded that self-editing is indeed effective in improving the writing performance of the students. In addition, they could make further revisions on their own errors. Through self-editing, the students were willing to provide further support to peers and learn from each other in the process of writing.Keywords: Self-editing, Discussion text, Writing
ACTIVE LEARNING STRATEGIES IN TEACHING CROSS CULTURAL UNDERSTANDING FOR ENGLISH EDUCATION STUDENTS
Authors: Pratama Ikke Dewi
Published: February 2018

Cross Cultural Understanding (CCU) is one of required courses in English Language Teaching which aims at connecting language and culture so that language learners can use foreign language appropriately, i.e. appropriate forms of language for appropriate context of situation. However, some obstacles usually occur during the course, for examples: students� lack of understanding that lead to opinions stating that this is a boring and useless course, and large number of students within a class where lecturer must teach more than 40 students in one class. Considering the importance of CCU course as well as the needs to overcome the problems during this course, this paper proposes some particular teaching strategies to help students in apprehending CCU materials through students� active participations. Active learning strategies are preferred by means of raising students� participation and critical thinking so that the class would run more effectively. Other consideration in composing the strategies is to prepare English Education students to be future English language teachers by training their ability in teaching performance as well as connecting language and culture in English Language Teaching (ELT). �Keywords: language, culture, strategies, media, ELT
�WEALTH OR LOVE, WHAT DOES A WOMAN WANT?� AN IRONIC LOOK AT THE MIDDLE CLASS NORMS IN CHARLOTTE BRONTE�S JANE EYRE
Authors: Murtiningrum Afina
Published: February 2018

Jane Eyre is a novel written in the early nineteenth century (1847). It depicts the English society of the upper, middle and lower class and their habits and attitudes towards life. The opening of the novel points to social class, wealth and marriage as its major theme. Throughout the novel, the relationship between social awareness of class and marriage, especially dealing with money or property are highlighted, the reason why society tends to consider about social class, money and property in finding a suitable partner to marry. This paper relies on the examples from the novel to show how nineteenth-century women imagined their marriage. In terms of women�s social rights and roles, Charlotte Bronte tries to open readers' eyes to the idea that women's abilities should not be limited only to the sphere of the family. Bronte�s novel does not only attack Victorian class structure but also the issue of gender. �Keywords : marriage, wealth, property, women�s roles, gender

Authors: Santiana Santiana , Fatimah Asri Siti
Published: February 2018

This study aims at analyzing reflection of the use of prezi as instructional media for teaching English in Indonesian context. Prezi is presentation software which is not commonly used in Indonesia producing a cloud-based presentation and storytelling tool for presenting ideas on a virtual canvas. This study is conducted based on the previous survey study done by Fox et.al (2016) finding that all of the students in their study preferred prezi rather than power point as a presentation tool in the areas of ease of use, fun to use, text, graphics, and usage in future presentations. However, this study has a purpose to reflect the student-teacher�s experience when using prezi in teaching English. To obtain the data, journal writing and self-observation by using video recording are used. It deeply investigates: 1) how he creates prezi for teaching English and 2) challenges and benefits of using it for teaching. The finding revealed that prezi is a powerful tool attracting the students� attention which creates better classroom atmosphere and meaningful learning experience. On the other hand, it encourages the teacher to have high access of internet and be creative on making prezi presentation.

The Dynamic Interaction Between Institutional Pressures and Activity: An Examination of the Implementation of IEPs in Secondary Inclusive Settings
Authors: Bray Laura E. , Russell Jennifer Lin
Published: February 2018

In this qualitative comparative case study, we drew from institutional theory and cultural historical activity theory to explore how educators wrote, used, and conceptualized the role of Individualized Education Programs (IEPs) for students with specific learning disabilities within secondary inclusive settings. We found that students’ IEPs were responding to institutional pressures to educate students within inclusive settings. However, the content of the students’ IEPs offered limited guidance on the activity of providing students with special education supports and services. With this being said, the IEPs still played distinctive roles in each school’s unique activity system for educating students within inclusive classrooms. Our findings illuminate a dynamic interaction between institutional pressures and the activity of providing students with a special education.
Relocalising academic literacy
Authors: Clemensen Nana , Holm Lars
Published: February 2018

This article contributes to the continuing discussion about academic literacy in international higher education. Approaching international study programmes as temporary educational contact zones, marked by a broad diversity in students’ educational and discursive experiences, we examine the negotiation and relocalisation of academic literacy among students of the international master’s programme, Anthropology of Education and Globalisation (AEG), University of Aarhus, Denmark. The article draws on an understanding of academic literacy as a local practice situated in the social and institutional contexts in which it appears. Based on qualitative interviews with eleven AEG-students, we analyse students’ individual experiences of, and perspectives on, the academic literacy practices of this study programme. Our findings reveal contradictory understandings of internationalism and indicate a learning potential for students in allowing a more linguistically and discursively diverse dialogue on knowledge production in academia.
Heritage or hate?
Authors: Lippard Cameron D.
Published: February 2018

The Confederate flag has been a hotly debated symbol of heritage or
hate in the United States. In 2015, 54 per cent of Americans polled
saw the flag as a symbol of ‘Southern pride’ whereas 34 per cent saw
it as racist. However, 27 per cent of Whites compared to 69 per cent
of Blacks saw the flag as racist. In this article, I suggest how instructors
can better explain this controversial topic within an America
society that is ‘post-race’. First, I describe an opening activity to get
students thinking about symbolism through flags. Next, I present a
lecture that debunks myths about the flag’s meanings by presenting
its factual history. Finally, I describe an open debate activity to
complete the discussion and comprehension of the confederate flag.
Student responses suggest that these lesson plans lead to a better
understanding of its symbolism and its relationship to the continuing
significance of racism in the U.S.
Donor nerve axotomy and axonal regeneration after end-to-side neurorrhaphy in a rodent model
Authors: Wang Shiwei , Su Diya , Li Jing , Li Dezhi , Wan Hong , Schumacher Michael , Liu Song
Published: February 2018

OBJECTIVE

In this study, the authors used a surgical model of end-to-side neurorrhaphy between a nerve graft and a donor tibial nerve in adult rats to investigate the optimal conditions for axonal regeneration induced by the donor nerve. They also assessed the importance of a more favorable pathway using a predegenerated nerve graft to attract regenerating axons to regrow into the graft and then directing and improving their growth toward the target in comparison with results obtained with a fresh nerve graft.

METHODS

End-to-side neurorrhaphy was performed between a nerve graft and a donor tibial nerve. The nerve graft was obtained from the left tibial nerve, which was either freshly removed or predegenerated 1 week prior to neurorrhaphy. The donor right tibial nerve was injured by epineurium removal alone, injured by epineurium removal with cross section of 20% or 50% of the total axons at the coaptation site, or left intact. The animals were followed postoperatively for a 6-week period, and outcomes were evaluated by optical microscopy and retrograde labeling to detect the regenerated primary sensory neurons located in the lumbar dorsal root ganglia and spinal motor neurons located in the lumbar spinal ventral horn.

RESULTS

At the end of the follow-up period, no regenerating axons were observed in the nerve grafts when the donor nerve was left intact, and very few axons were detected when the donor nerve was injured by epineurium removal alone. However, numerous regenerating axons appeared in the grafts when the donor nerve was axotomized, and the greatest number was achieved with a 50% cross section axotomized nerve. In the rats with a 50% cross section of the donor nerve, better nerve-like morphology of the grafts was observed, without connective adhesions. When a predegenerated nerve graft was used, more regenerating axons were attracted and elongated with a more regular shape and improved myelination.

CONCLUSIONS

Axonal regrowth into a nerve graft depends on axotomy of the donor nerve after end-to-side neurorrhaphy. More efficient attraction and an improved structure of the regenerating axons were achieved when a predegenerated nerve graft was used. Furthermore, a nerve graft may require a certain number of regenerating axons to maintain a nerve-like morphology.

Published: February 2018

OBJECTIVE

The aim of this study was to implement cumulative summation (CUSUM) analysis as an early-warning detection and quality assurance system for preclinical testing of the iSYS1 novel robotic trajectory guidance system.

METHODS

Anatomically accurate 3D-printed skull phantoms were created for 3 patients who underwent implantation of 21 stereoelectroencephalography electrodes by surgeons using the current standard of care (frameless technique). Implantation schema were recreated using the iSYS1 system, and paired accuracy measures were compared with the previous frameless implantations. Entry point, target point, and implantation angle accuracy were measured on postimplantation CT scans. CUSUM analysis was undertaken prospectively.

RESULTS

The iSYS1 trajectory guidance system significantly improved electrode entry point accuracies from 1.90 ± 0.96 mm (mean ± SD) to 0.76 ± 0.57 mm (mean ± SD) without increasing implantation risk. CUSUM analysis was successful as a continuous measure of surgical performance and acted as an early-warning detection system. The surgical learning curve, although minimal, showed improvement after insertion of the eighth electrode.

CONCLUSIONS

The iSYS1 trajectory guidance system did not show any increased risk during phantom preclinical testing when used by neurosurgeons who had no experience with its use. CUSUM analysis is a simple technique that can be applied to all stages of the IDEAL (idea, development, exploration, assessment) framework as an extra patient safety mechanism. Further clinical trials are required to prove the efficacy of the device.
Reinnervation of the rectum with transfer of the genital branch of the genitofemoral nerve to the pelvic nerve in rats
Authors: Dong Chuanjiang , Zhu Ping , Xie Zonglan , Fan Zheqi , Dong Ziqiang
Published: February 2018

OBJECTIVE

The purpose of this study was to determine the feasibility of rectum reinnervation with transfer of a primarily genitofemoral nerve to the pelvic nerve in the rat.

METHODS

Thirty-six male rats were randomly divided into 3 groups: rats in the nerve transfer group (n = 12) were subjected to rectal denervation and then bilateral genitofemoral nerve–pelvic nerve transfer; rats in the nerve resection group (n = 12) underwent rectum denervation without nerve transfer; and rats in the control group (n = 12) underwent sham surgery. Rectum denervation was achieved by transection of the L-6 spinal nerves, the spinal nerves below L-6, and the pelvic nerve. Four months postoperatively, retrograde nerve tracing, regenerative nerve morphological examination, and rectal manometry assessment were performed.

RESULTS

Regenerative nerve morphological examination showed good axonal regeneration after genitofemoral nerve transfer. Nerve stimulation induced increased rectal pressures in 10 of 12 rats in the nerve transfer group. The mean rectal pressure in this group was 54.9 ± 7.1 mm Hg, which is higher than the mean value in the nerve resection group (5.5 ± 2.0 mm Hg) but lower than that in the control group (70.6 ± 8.5 mm Hg) (p < 0.05). The appearance of FluoroGold-labeled neurons in the L-1 and L-2 spinal cord segments in the nerve transfer group confirmed the formation of new neural pathways.

CONCLUSIONS

The results have demonstrated that genitofemoral nerve–pelvic nerve transfer can achieve nerve regeneration. In this animal model, the authors were able to reinnervate the rectum by nerve transfer.
High-resolution Laboratory Measurements of Coronal Lines near the Fe ix Line at 171 Å
Authors: Beiersdorfer Peter , Träbert Elmar
Published: February 2018

We present high-resolution laboratory measurements in the spectral region between 165 and 175 Å that focus on the emission from various ions of C, O, F, Ne, S, Ar, Fe, and Ni. This wavelength region is centered on the λ171 Fe ix channel of the Atmospheric Imaging Assembly on the Solar Dynamics Observatory, and we place special emphasis on the weaker emission lines of Fe ix predicted in this region. In general, our measurements show a multitude of weak lines missing in the current databases, where the emission lines of Ni are probably most in need of further identification and reclassification. We also find that the wavelengths of some of the known lines need updating. Using the multi-reference Møller–Plesset method for wavelength predictions and collisional-radiative modeling of the line intensities, we have made tentative assignments of more than a dozen lines to the spectrum of Fe ix, some of which have formerly been identified as Fe vii, Fe xiv, or Fe xvi lines. Several Fe features remain unassigned, although they appear to be either Fe vii or Fe x lines. Further work will be needed to complete and correct the spectral line lists in this wavelength region.
On Mapping Exoplanet Atmospheres with High-dispersion Spectro-polarimetry: Some Model Predictions
Authors: García Muñoz A.
Published: February 2018

Planets reflect and linearly polarize the radiation that they receive from their host stars. The emergent polarization is sensitive to aspects of the planet’s atmosphere such as the gas composition and the occurrence of condensates and their optical properties. Extracting this information will represent a major step in the characterization of exoplanets. The numerical simulations presented here show that the polarization of a spatially unresolved exoplanet may be detected by cross-correlating high-dispersion linear polarization and intensity (brightness) spectra of the planet–star system. The Doppler shift of the planet-reflected starlight facilitates the separation of this signal from the polarization introduced by the interstellar medium and the terrestrial atmosphere. The selection of the orbital phases and wavelengths at which to study the planet is critical. An optimal choice, however, will partly depend on information about the atmosphere that is a priori unknown. We elaborate on the cases of close-in giant exoplanets with non-uniform cloud coverage, an outcome of recent surveys of brightness phase curves from space, and for which the hemispheres east and west of the substellar point will produce different polarizations. With integration times of the order of hours at a 10 m telescope, the technique might distinguish among some proposed asymmetric cloud scenarios with fractional polarizations of 10 parts per million for one such planet orbiting a V-mag = 5.5 host star. Future 30–40 m telescopes equipped with high-dispersion spectro-polarimeters will be able to investigate the linear polarization of smaller planets orbiting fainter stars and look for molecular features in their polarization spectra.

We present a multiwavelength study to probe the star formation (SF) process in the molecular cloud linked with the G35.673-00.847 site (hereafter MCG35.6), which is traced in a velocity range of 53–62 km s−1. Multiwavelength images reveal a semi-ring-like feature (associated with ionized gas emission) and an embedded face-on ring-like feature (without the NVSS 1.4 GHz radio emission, where 1σ ∼ 0.45 mJy beam−1) in MCG35.6. The semi-ring-like feature is originated by the ionizing feedback from a star with spectral type B0.5V–B0V. The central region of the ring-like feature does not contain detectable ionized gas emission, indicating that the ring-like feature is unlikely to be produced by the ionizing feedback from a massive star. Several embedded Herschel clumps and young stellar objects (YSOs) are identified in MCG35.6, tracing the ongoing SF activities within the cloud. The polarization information from the Planck and GPIPS data trace the plane-of-sky magnetic field, which is oriented parallel to the major axis of the ring-like feature. At least five clumps (having M
clump ∼ 740–1420 M
⊙) seem to be distributed in an almost regularly spaced manner along the ring-like feature and contain noticeable YSOs. Based on the analysis of the polarization and molecular line data, three subregions containing the clumps are found to be magnetically supercritical in the ring-like feature. Altogether, the existence of the ring-like feature and the SF activities on its edges can be explained by the magnetic field mediated process as simulated by Li & Nakamura.

Objective.

Exclusion of psoriatic skin/nail lesions is important in differentiating early seronegative rheumatoid arthritis (ERA) from early polyarticular psoriatic arthritis (EPsA) and such manifestations may go unnoticed in atypical or minimally expressed cases. The aim of this study is to assess the usefulness of integrated rheumatological-dermatological evaluation in highlighting dermatological lesions missed on rheumatological examination and to investigate the role of ultrasonography (US) and dermoscopy in improving the recognition of subclinical psoriatic findings.

Methods.

Patients with a new diagnosis of seropositive or seronegative ERA and EPsA with prevalent hands involvement were recruited. All were reassessed for the presence of psoriatic lesions during an integrated rheumatological-dermatological clinical evaluation and underwent hands US and proximal nailfold dermoscopy.

Results.

Seventy-three consecutive subjects were included in the study: 25 with seropositive ERA, 23 with seronegative ERA, and 25 with EPsA. One-fourth of the subjects initially diagnosed as seronegative ERA presented cutaneous or nail psoriasis on integrated rheumatological-dermatological evaluation, thereby being reclassified as EPsA. The presence of at least 1 extrasynovial feature on hand US and dotted vessels on proximal nailfold dermoscopy was significantly associated with EPsA, with a sensitivity of 68.0% and 96.0% and a specificity of 88.1% and 83.3% for US and dermoscopy, respectively. When used together, specificity for PsA diagnosis raised to 90.5%.

Conclusion.

Integrated rheumatological-dermatological clinical evaluation may be helpful in identifying patients with EPsA misclassified as seronegative ERA. Additionally, US and dermoscopy may be used as supportive tools in identifying subclinical psoriatic features, which may come in handy in distinguishing EPsA from ERA.
Les Algériennes, citoyennes à part entière ?
Authors: Bouatta Cherifa
Published: February 2018

Ce texte rend compte des luttes menées par les féministes algériennes en vue d’obtenir des lois égalitaires. Le Code de la famille – promulgué en 1984 – attribue un statut inférieur aux femmes. À travers leurs associations, les féministes algériennes rejettent ce code en s’appuyant sur la Constitution algérienne qui stipule l’égalité entre tous les citoyens et les droits universels. Ce combat est mené contre le régime algérien et contre les islamistes qui revendiquent des lois inspirées de la chari’a . Être citoyenne, c’est revendiquer les mêmes droits pour les femmes et les hommes, dans un État de droit qui promeut la justice sociale, l’égalité devant le droit et l’indépendance de la justice.
Citoyennetés, laïcités et religions, un « triangle » en permanence sous tension
Authors: Blanc Maurice
Published: February 2018

Je suis né dans une famille divisée par la religion catholique : d’un côté, une vision ritualiste et individualiste, de l’autre, une vision sociale. J’ai choisi un catholicisme social, coopérant avec des non-chrétiens et m’opposant à la droite catholique. Les discours sur les valeurs sont secondaires pour moi, l’épreuve de vérité est leur mise en pratique concrète. Je me suis éloigné des religions (y compris celle de la laïcité), passant d’une vision sociale à une vision politique : il faut agir sur les causes structurelles des défaillances du système social. Dans la vie quotidienne, la citoyenneté active admet les religions dans le débat politique, mais dans une stricte égalité avec les autres participant(e)s. Dans cette laïcité inclusive , « la loi de Dieu » est soumise à la loi de l’ensemble des hommes et des femmes. Cette dernière s’élabore collectivement, en faisant des compromis sans compromission pour parvenir au bien commun. Ce processus de transaction sociale vise, sans supprimer la tension, à concilier les valeurs et les intérêts de tous.

À partir de Kamel Daoud : essentialisme et universalisme contre désir de citoyenneté figée
Authors: Bouatta Cherifa
Published: February 2018

Kamel Daoud est un chroniqueur algérien qui soulève les questions les plus épineuses et les plus sensibles, voire les tabous, de la société algérienne. Il s’autorise à critiquer le religieux, à s’exprimer sur la sexualité et l’hypocrisie qui l’entoure, ainsi que sur les frustrations qui en découlent. Il a écrit une chronique ( Le Monde , 31 janvier 2016) sur ce qu’on a appelé « les événements de Cologne » où il dénonce les comportements des migrants soupçonnés d’être les auteurs des agressions sexuelles contre des femmes occidentales. Il a été vilipendé, accusé d’essentialisme par des intellectuels occidentaux bien-pensants et voué aux gémonies par des intellectuels algériens, l’accusant de trahison. Ce texte discute les thèses développées par Kamel Daoud et celles des tenants de la morale dominante, tout en contextualisant leurs propos et en ouvrant des pistes de réflexion sur l’essentialisme et l’universalisme (ou l’universalisable).
L’islam dans une France et une Europe laïques : comment déjouer les pièges de l’extrémisme prétendu musulman ?
Authors: Blanc Maurice
Published: February 2018

Ce texte analyse la place de l’islam en France et en Europe. Il distingue ses formes pacifiques et ses tendances extrémistes et meurtrières. Il soutient que l’islam devrait avoir les mêmes droits et les mêmes devoirs que les religions chrétiennes, en France et dans l’Union européenne (UE). Il considère que les explications de l’extrémisme islamiste par les conditions socio-économiques locales, par les séquelles de la colonisation, ou par l’islam, sont complémentaires et ne s’excluent pas mutuellement. L’extrémisme islamiste est à la fois exogène et endogène à la France et à l’UE. Il y a beaucoup à faire en matière de dés-endoctrinement et le système carcéral est inadapté, particulièrement en France. La collaboration de tous les échelons de l’État avec la société civile est requise, dans une démocratie participative repensée et élargie.
The Effects of Platelet-Rich Plasma and Activated Collagen on Wound Healing in Primary Total Joint Arthroplasty
Authors: Evans David C. , Evans Bruce G.
Published: February 2018

Wound healing remains a concern in primary total joint arthroplasty, given the risk of deep infections arising from hematomas, wound separations, and superficial infections. If wound additives can prevent these early complications, their universal application would be cost-effective. This study examined whether 2 wound additives, platelet-rich plasma (PRP) and activated collagen, would improve postoperative wound healing and reduce complications in primary total joint arthroplasty. A prospective, randomized controlled study was conducted using 3 cohorts with 30 patients each (group 1: PRP; group 2: activated collagen; and group 3: control). These patients were examined at 2 and 6 weeks postoperatively, at which time the following data were recorded: 6 wound measurements, total postoperative blood loss, complications of superficial infections, and reoperations. The PRP and the activated collagen groups showed early improvement in 3 of the 6 wound scores at 2 weeks, but these early results were not present at 6 weeks. In addition, there was a statistically significant reduction in blood loss in both the PRP and the activated collagen groups, as compared with the control group. Furthermore, high-risk patients had a statistically significant reduction in total complication rates in both the PRP and the activated collagen groups, as compared with the control group. On the basis of this study, these additives are not recommended for routine primary joint arthroplasty; however, the data suggest possible benefits for high-risk patients and those for whom blood loss may be an issue.
