Creating the Ideal Digital Self: 3G Mobile Phone Content Production and Distribution as Social Communication

Mobile phone ownership presents users with the opportunity to regularly update others of their actions through the digital documentation and circulation of their experiences. There is a sense that an event is not complete until it is shared through text, voice or images. An empirical study of 35 users aged 18-30, conducted for the Smart Internet Technology CRC [3] revealed that when members of a social group cannot be together physically, circulating digitised accounts of an activity becomes an authentic way to share the event. Furthermore, the study indicated that with the convergence of 3G mobile phones, digital cameras and the Internet, users are taking advantage of the best of all three communication channels to create, circulate, distribute and archive content in new and dynamic ways. Through this process users are creating the 'ideal digital self' by which to communicate socially. However, the effectiveness of these new practices is eroded by specific design and technological limitations, thus a distinct set of user problems emerged. This paper illustrates how the Trophy Room scenario, which is a 3G phone and web application, was developed to address the user needs identified in the study

Tense or Aspect? Effects of L1 Prominence in L2 Acquisition

This study introduces a typological model of the conceptual language-specific approach to the L2 research on the acquisition of tense-aspect. The model is based on the typological notion of prominence, classifying languages into tense-prominent and aspect-prominent (Bhat 1999) and the L1 research proposal that language-specific lexicalization patterns have a role in shaping form-function mappings in child language (Berman and Slobin 1994, Slobin 1991, 1996a, 1996b). The study represents an attempt to investigate language-specific L1 effects (Odlin 2005) in the L2 acquisition of complex form-function grammatical domains, such as tense-aspect. The most influential L2 tense-aspect research has focused on the acquisition of verb morphology (form-to-function analysis) and the acquisition of temporality (function-to-form analysis, respectively (Bardovi-Harlig 2000). The research investigated the Aspect Hypothesis (Andersen 1991, Andersen and Shirai 1994, Bardovi-Harlig 1992), the Discourse Hypothesis (Bardovi-Harlig 1995), and the Prototype Hypothesis (Shirai 1991, Li and Shirai 2000). Based on Vendler (1967), these studies explore the L2 acquisition of inherent verb aspect in comparison to grammatical aspect and tense. L2 research on specific L1/L2 contexts has not been of major interests to the L2 scholars. Turning to the specific L1/L2 features of tense-aspect prominence and aspect-prominence, this bi-directional study tests the Grammatical Domain Hypothesis (GDH) with two groups of intermediate--high intermediate instructed L2 learners: L1 English (tense-prominent)/L2 Russian (N=21) and L1 Russian (aspect-prominent/L2 English (N= 11). The L2 data were elicited on two written tasks: a cloze task and a Frog Story task, with the native speaker responses as the baseline for both tasks. The results are categorized as follows: target/non-target use of tense-aspect (task 1); non-target morphological forms, tense-aspect substitutions, lexical aspectual means, and idiosyncratic clausal strategies (task 2). The findings reveal L2 tendencies supporting the GDH: L1 English/L2 Russian learners show \u27tense bias\u27, while limiting the aspectual choices. Conversely, L1 Russian/L2 English learners show \u27aspect bias\u27 while inconsistently mixing L2 tenses. Potential methodological and interpretation problems are presented in the conclusion, followed by the pedagogical implications the study may have on the instructional methods in teaching tense-aspect to L2 learners from the typologically mismatching L1\u27s

Lead in Tap Water from University District Region, Columbus, OH: Evaluation of Lead and Copper Rule and Revisions Sampling Guidance Across Service Line Compositions

Denman Undergraduate Research Forum, Third Place in Earth & BeyondLead is a potent toxin that can cause a myriad of health effects, most notably adverse effects in pregnancy and neurological changes in children. Due to the health effects of lead exposure, regulations are in place to minimize lead exposure to the public. This study focuses on lead concentrations of tap water in Columbus, OH, and how the presence or absence of a lead service line impacts household tap water lead levels. The change in sampling directives from the EPA's Lead and Copper Rule (1991) to the Lead and Copper Rule Revisions (2021) were also examined, taking both the first and fifth liters of water for analysis. Buildings were selected for sampling in north-central Columbus to include a mix of service line compositions according to published data from the Columbus Department of Public Utilities. Samples were collected using the clean hands/dirty hands technique of trace element sampling, and then analyzed for lead using an ICP-MS. Major cations and anions were also analyzed in the tap water samples. Differences in lead concentration between buildings serviced by lead lines and by non-lead lines were not significant, which may suggest that Columbus's corrosion control treatments are working. Changes in lead levels from the first to the fifth liter were significant in non-lead pipes, with liter one having higher concentrations of lead. These changes were not significant in lead pipes, though notable outliers of 1.09 μg/L and 0.38 μg/L were present in liter five. Our previous work on tap water from numerous Ohio State University campus buildings indicates low, but measurable amounts of lead in all samples with a mean concentration of 1.2 μg/L (n=20). Off-campus buildings had lower levels than the on-campus samples, with a mean concentration of 0.13 μg/L (n=31).Byrd Polar and Climate Research CenterHonors and Scholars FundSecond Year Transformational Experience ProgramSchool of Earth SciencesA one-year embargo was granted for this item.Academic Major: Environmental Scienc

Authentication and authorisation in entrusted unions

This paper reports on the status of a project whose aim is to implement and demonstrate in a real-life environment an integrated eAuthentication and eAuthorisation framework to enable trusted collaborations and delivery of services across different organisational/governmental jurisdictions. This aim will be achieved by designing a framework with assurance of claims, trust indicators, policy enforcement mechanisms and processing under encryption to address the security and confidentiality requirements of large distributed infrastructures. The framework supports collaborative secure distributed storage, secure data processing and management in both the cloud and offline scenarios and is intended to be deployed and tested in two pilot studies in two different domains, viz, Bio-security incident management and Ambient Assisted Living (eHealth). Interim results in terms of security requirements, privacy preserving authentication, and authorisation are reported

NATIONALISM DURING ARMED CONFLICT: A STUDY OF IDEOLOGY AND IDENTITY IN THE BOSNIAN WAR, 1992-1995

This dissertation asks when and why leaders and members of ethno-religious groups choose to express one type of nationalist ideology and ethnic identity during armed conflict instead of another. It argues that patterns of wartime violence and external actors play direct and indirect roles in making certain forms of nationalism and ethnic identity more useful for dealing with wartime circumstances. The dissertation advances this argument by joining together four independent empirical chapters. Each empirical chapter has its own research question, its own dependent variable, and its own theoretical argument. All four chapters focus on one ethno-religious group in conflict: the Bosnian Muslims during the 1990s war in Bosnia. Methodologically, I apply statistical analysis to an original dataset of over 3,700 speech acts by Bosnian Muslim leaders of the wartime Bosnian government in order to explain why the frequency and form of their wartime nationalist rhetoric varied. I also employ historical evidence and qualitative text analysis to reveal the mechanisms underlying the statistical relationships. In addition, one of the empirical chapters analyzes survey data to explain why, following the war, some Bosnian Muslims supported politicians that made religious appeals. Using this approach, the dissertation finds the following results. First, intense violence against the predominantly Bosnian Muslim population of wartime Sarajevo prompted the Bosnian Muslim leaders of the Bosnian government to use nationalist ideological claims more frequently in domestic media. Second, contingent wartime events spurred these leaders to shift their rhetoric in domestic media from civic to ethnic nationalism in the second year of the war. Specifically, internal power struggles and external peace proposals increased the usefulness of making ethnic nationalist claims to domestic audiences. Third, Bosnian leaders’ need for external aid combined with their uncertain likelihood of receiving Western military support led them to use both civic and religious nationalist rhetoric in foreign media. Fourth, Bosnian Muslims who experienced internal displacement during the war became more religious as a means of coping with the trauma of displacement, which in turn made them more likely to vote for religiously oriented politicians after the conflict

The translational regulator dFMRP interacts with epidermal growth factor receptor to regulate apoptosis in Drosophila

poster abstractPosttranscriptional gene regulation is required for all aspects of cellular and tissue development and is a major mechanism underlying many diseases ranging from neurological disorders to cancer. The translational repressor fragile x mental retardation protein (FMRP) is ubiquitously expressed throughout development but is silenced in Fragile X Syndrome, an autism spectrum disorder. Interestingly, high levels of FMRP have recently been identified in human metastatic breast cancer. FMRP overexpression in these patients is directly correlated with increased lung metastasis suggesting a direct role for translational regulation both in cell proliferation and in invasive cell migration. Interestingly, however, FMRP can promote both proliferation and apoptosis. To dissect FMRP’s role in cancer development and progression, we are exploiting the powerful genetic system of Drosophila. Drosophila is an excellent model organism for human diseases associated with FMRP due to the strong evolutionary conservation of the fragile x mental retardation gene 1 which encodes this protein. dFMRP was overexpressed in the Drosophila imaginal wing disc, an epithelial tissue model. Contrary to a role in proliferation, overexpression of dFMRP leads to obvious cell loss in the adult wing and an increase in apoptotic markers. Using a combinatorial genetic screen, we have identified genes which are able to suppress this apoptotic phenotype and thus may be important for FMRP-­‐dependent tumorigenesis. Our focus is now on the epidermal growth factor receptor (EGFR) signaling pathway since blocking this mechanism is able to completely rescue the dFMRP-­‐overexpression wing defects. Clonal analysis reveals that dFMRP overexpressing cells survive their dFMRP-­induced apoptotic programming when co-­‐expressing a dominant negative form of EGFR. Additional clonal analyses are being used to explore the potential significance of this survival on tumor formation and metastasis
