International teachers in the American classroom : deposing the myth of monolingualism

An international graduate teaching assistant‘s way of speaking may pose a challenge for college students enrolled in STEM courses at American universities. Students commonly complain that unfamiliar accents interfere with their ability to comprehend the IGTA or that they have difficulty making sense of the IGTA‘s use of words or phrasing. These frustrations are echoed by parents who pay tuition bills. The issue has provoked state and national legislative debates over universities‘ use of IGTAs. However, potentially productive debates and interventions have been stalemated due to the failure to confront deeply embedded myths and cultural models that devalue otherness and privilege dominant peoples, processes, and knowledge. My research implements a method of inquiry designed to identify and challenge these cultural frameworks in order to create an ideological/cultural context that will facilitate rather than impede the valuable efforts that are already in place. Discourse theorist Paul Gee‘s concepts of master myth, cultural models, and meta-knowledge offer analytical tools that I have adapted in a unique research approach emphasizing triangulation of both analytic methods and data sites. I examine debates over IGTA‘s use of language in the classroom among policy-makers, parents of college students, and scholars and teachers. First, the article "Teach Impediment" provides a particularly lucid account of the public debate over IGTAs. My analysis evidences the cultural hold of the master myth of monolingualism in public policy-making. Second, Michigan Technological University‘s email listserve Parentnet is analyzed to identify cultural models supporting monolingualism implicit in everyday conversation. Third, a Chronicle of Higher Education colloquy forum is analyzed to explore whether scholars and teachers who draw on communication and linguistic research overcome the ideological biases identified in earlier chapters. My analysis indicates that a persistent ideological bias plays out in these data sites, despite explicit claims by invested speakers to the contrary. This bias is a key reason why monolingualism remains so tenaciously a part of educational practice. Because irrational expectations and derogatory assumptions have gone unchallenged, little progress has been made despite decades of earnest work and good intentions. Therefore, my recommendations focus on what we say not what we intend.

DESIGN AND IMPLEMENTATION OF HOME USE PORTABLE SMART ELECTRONICS

The widespread of low cost embedded electronics makes it easier to implement the smart devices that can understand either the environment or the user behaviors. The main object of this project is to design and implement home use portable smart electronics, including the portable monitoring device for home and office security and the portable 3D mouse for convenient use. Both devices in this project use the MPU6050 which contains a 3 axis accelerometer and a 3 axis gyroscope to sense the inertial motion of the door or the human hands movement. For the portable monitoring device for home and office security, MPU6050 is used to sense the door (either home front door or cabinet door) movement through the gyroscope, and Raspberry Pi is then used to process the data it receives from MPU6050, if the data value exceeds the preset threshold, Raspberry Pi would control the USB Webcam to take a picture and then send out an alert email with the picture to the user. The advantage of this device is that it is a small size portable stand-alone device with its own power source, it is easy to implement, really cheap for residential use, and energy efficient with instantaneous alert. For the 3D mouse, the MPU6050 would use both the accelerometer and gyroscope to sense user hands movement, the data are processed by MSP430G2553 through a digital smooth filter and a complementary filter, and then the filtered data will pass to the personal computer through the serial COM port. By applying the cursor movement equation in the PC driver, this device can work great as a mouse with acceptable accuracy. Compared to the normal optical mouse we are using, this mouse does not need any working surface, with the use of the smooth and complementary filter, it has certain accuracy for normal use, and it is easy to be extended to a portable mouse as small as a finger ring.

Chinese Internet language: A sociolinguistic analysis of adaptations of the Chinese writing system

This paper examines the adaptations of the writing system in Internet language in mainland China from a sociolinguistic perspective. A comparison is also made of the adaptations in mainland China with those that Su (2003) found in Taiwan. In Computer-Mediated Communication (CMC), writing systems are often adapted to compensate for their inherent inadequacies (such as difficulty in input). Su (2003) investigates the creative uses of the writing system on the electronic bulletin boards (BBS) of two college student organizations in Taipei, Taiwan, and identifies four popular and creative uses of the Chinese writing system: stylized English, stylized Taiwanese-accented Mandarin, stylized Taiwanese, and the recycling of a transliteration alphabet used in elementary education. According to Coupland (2001; cited in Su 2003), stylization is “the knowing deployment of culturally familiar styles and identities that are marked as deviating from those predictably associated with the current speaking context”. Within this framework and drawing on the data in previous publications on Internet language and online sources, this study identifies five types of adaptations in mainland China’s Internet language: stylized Mandarin (e.g., 漂漂 piāopiāo for 漂亮 ‘beautiful’), stylized dialect-accented Mandarin (e.g., 灰常 huīcháng for 非常 ‘very much’), stylized English (e.g., 伊妹儿 yīmèier for ‘email’), stylized initials (e.g., bt 变态 biàntài for ‘abnormal’; pk, short form for ‘player kill’), and stylized numbers (e.g., 9494 jiùshi jiùshi 就是就是 ‘that is it’). The Internet community is composed of highly mobile individuals and thus forms a weak-tie social network. According to Milroy and Milroy (1992), a social network with weak ties is often where language innovation takes place. Adaptations of the Chinese writing system in Internet language provide interesting evidence for the innovations within a weak-tie social network. Our comparison of adaptations in mainland China and Taiwan shows that, in maximizing the effectiveness and functionality of their communication, participants of Internet communication are confronted with different language resources and situations, including differences in Romanization systems, English proficiency level, and attitudes towards English usage. As argued by Milroy and Milroy (1992), a weak-tie social network model can bridge the social class and social network. In the Internet community, the degree of diversity of the stylized linguistic varieties indexes the virtual and/or social status of its participants: the more diversified one’s Internet language is, the higher is his/her virtual and/or social status.

Facebook’s Real Name Policy: Bye-Bye, Max Mustermann?

Facebook requires all members to use their real names and email addresses when joining the social network. Not only does the policy seem to be difficult to enforce (as the prevalence of accounts with people’s pets or fake names suggests), but it may also interfere with European (and, in particular, German) data protection laws. A German Data Protection Commissioner recently took action and ordered that Facebook permit pseudonymous accounts as its current anti-pseudonymous policy violates § 13 VI of the German Telemedia Act. This provision requires telemedia providers to allow for an anonymous or pseudonymous use of services insofar as this is reasonable and technically feasible. Irrespective of whether the pseudonymous use of Facebook is reasonable, the case can be narrowed down to one single question: Does German data protection law apply to Facebook? In that respect, this paper analyses the current Facebook dispute, in particular in relation to who controls the processing of personal data of Facebook users in Germany. It also briefly discusses whether a real name policy really presents a fix for anti-normative and anti-social behaviour on the Internet.

Virtues and Perils of Anonymity: Should Intermediaries Bear the Burden?

On October 10, 2013, the Chamber of the European Court of Human Rights (ECtHR) handed down a judgment (Delfi v. Estonia) condoning Estonia for a law which, as interpreted, held a news portal liable for the defamatory comments of its users. Amongst the considerations that led the Court to find no violation of freedom of expression in this particular case were, above all, the inadequacy of the automatic screening system adopted by the website and the users’ option to post their comments anonymously (i.e. without need for prior registration via email), which in the Court’s view rendered the protection conferred to the injured party via direct legal action against the authors of the comments ineffective. Drawing on the implications of this (not yet final) ruling, this paper discusses a few questions that the tension between the risk of wrongful use of information and the right to anonymity generates for the development of Internet communication, and examines the role that intermediary liability legislation can play to manage this tension.

Although several validation studies have been performed on specific anatomical sites and load cases, this study aims to review the predictability of human bone strength at the three major osteoporotic fracture sites quantified in recently completed in vitro studies at our former institute. Specifically, the performance of FE analysis based on clinical computer tomography (QCT) is compared with the ones of the current densitometric standards, bone mineral content, bone mineral density (BMD) and areal BMD (aBMD). Clinical fractures were produced in monotonic axial compression of the distal radii, vertebral sections and in side loading of the proximal femora. QCT-based FE models of the three bones were developed to simulate as closely as possible the boundary conditions of each experiment. For all sites, the FE methodology exhibited the lowest errors and the highest correlations in predicting the experimental bone strength. Likely due to the improved CT image resolution, the quality of the FE prediction in the peripheral skeleton using high-resolution peripheral CT was superior to that in the axial skeleton with whole-body QCT. Because of its projective and scalar nature, the performance of aBMD in predicting bone strength depended on loading mode and was significantly inferior to FE in axial compression of radial or vertebral sections but not significantly inferior to FE in side loading of the femur. Considering the cumulated evidence from the published validation studies, it is concluded that FE models provide the most reliable surrogates of bone strength at any of the three fracture sites.

Internetbasierte geleitete Selbsthilfeansätze bei Angststörungen und Depressionen

Das Spektrum internetbasierter psychologischer Behandlungsangebote bei psychischen Problemen und Erkrankungen bewegt sich zwischen webbasierten Selbsthilfeprogrammen, die das Internet als Informationsmedium verwenden, und Email-, Chat- und Video-Therapien, in welchen das Internet zu Kommunikationszwecken zwischen Hilfesuchenden und Professionellen genutzt wird. Dieser Beitrag fokussiert auf eine Beratungs- und Therapieform, die die Möglichkeiten des Internets als Informations- und Kommunikationsmedium in sogenannten geleiteten Selbsthilfeansätzen kombiniert. Internetbasierte geleitete Selbsthilfeansätze, in welchen Klienten während der Bearbeitung eines Selbsthilfeprogramms von Therapeuten via Internet (z.B. Email) unterstützt werden, wurden in den letzten Jahren intensiv erforscht. Im Bereich von Angststörungen und Depressionen liegen besonders viele Studien vor. Verschiedene Forschergruppen haben hier in der Regel große Behandlungseffekte gefunden, die mit der Wirkung von Face-to-Face-Therapien vergleichbar sind. In diesem Beitrag wird der geleitete Selbsthilfeansatz dargestellt und die empirische Evidenz diskutiert.

Internetbasierte geleitete Selbsthilfe bei verschiedenen Angststörungen: Eine randomisiert kontrollierte Studie zum Vergleich eines individualisierten vs. standardisierten Ansatzes

Hintergrund und Ziel: Internetbasierte psychotherapeutische Interventionen wurden in den letzten Jahren intensiv erforscht. Als besonders vielversprechend haben sich therapeutengeleitete Selbsthilfeprogramme bei verschiedenen Angststörungen erwiesen. Eine neue Entwicklung sind transdiagnostische und individualisierte Ansätze, in welchen auch komorbide Probleme und Störungen, und breitere Patientengruppen angesprochen werden. Beim individualisierten Ansatz werden dem Selbsthilfeprogramm in Abhängigkeit der Probleme der Patienten unterschiedliche Inhalte zugeschaltet. Das Ziel dieser Studie ist die Evaluation einer internetbasierten, individualisierten, geleiteten Selbsthilfeintervention für verschiedene Angststörungen. Methode: In einer kontrolliert-randomisierten Studie wurde der individualisierte Ansatz mit einer standardisierten Intervention, die sich nur auf die primäre Störung der Klienten bezieht, verglichen. 132 StudienteilnehmerInnen, diagnostiziert mit einer Sozialen Angststörung, Panikstörung mit oder ohne Agoraphobie, und/ oder einer Generalisierten Angststörung wurden randomisiert einer der beiden Behandlungsbedingungen oder einer Warteliste zugeteilt. Die Selbsthilfebehandlung dauerte 8 Wochen und wurde von Therapeuten via Email unterstützt. Erhebungszeitpunkte waren Prä, Post und 6 Monate nach Ende der Behandlung. Primäre Ergebnismasse sind störungsübergreifende Masse wie das Beck Angstinventar (BAI) und Daten aus einem diagnostischen Interview. Sekundäre Ergebnismasse sind störungsspezifische Fragebogen. Ergebnisse: Beide Behandlungsgruppen zeigten gegenüber der Warteliste-Kontrollgruppe signifikante Veränderungen auf allen Ergebnismassen. Auf der Basis der Intent-to-treat-Stichprobe betrugen die über die verschiedenen Ergebnismasse gemittelten Effektstärken im Vergleich zur Warteliste-Kontrollgruppe d=.80 für die individualisierte und d=.82 für die standardisierte Behandlungsbedingung. Die Symptomreduktion wurde bis zum 6-Monats-Follow-Up aufrechterhalten. Zwischen den beiden aktiven Behandlungsbedingungen wurden keine Unterschiede gefunden. Diskussion: Die Ergebnisse zeigen, dass sowohl individualisierte wie auch standardisierte internetbasierte Ansätze zur Behandlung verschiedener Angststörungen vielversprechend sind

International standards for programmes of training in intensive care medicine in Europe.

PURPOSE To develop internationally harmonised standards for programmes of training in intensive care medicine (ICM). METHODS Standards were developed by using consensus techniques. A nine-member nominal group of European intensive care experts developed a preliminary set of standards. These were revised and refined through a modified Delphi process involving 28 European national coordinators representing national training organisations using a combination of moderated discussion meetings, email, and a Web-based tool for determining the level of agreement with each proposed standard, and whether the standard could be achieved in the respondent's country. RESULTS The nominal group developed an initial set of 52 possible standards which underwent four iterations to achieve maximal consensus. All national coordinators approved a final set of 29 standards in four domains: training centres, training programmes, selection of trainees, and trainers' profiles. Only three standards were considered immediately achievable by all countries, demonstrating a willingness to aspire to quality rather than merely setting a minimum level. Nine proposed standards which did not achieve full consensus were identified as potential candidates for future review. CONCLUSIONS This preliminary set of clearly defined and agreed standards provides a transparent framework for assuring the quality of training programmes, and a foundation for international harmonisation and quality improvement of training in ICM.
