Data protection: the challenges facing social networking
Get PDFThe popularity of social networking sites has increased dramatically over the past decade. A recent report indicated that thirty-eight percent of online users have a social networking profile. Many of these social networking site users (SNS users) post or provide personal information over the internet every day. According to the latest OfCom study, the average adult SNS user has profiles on 1.6 sites and most check their profiles at least once every other day. However, the recent rise in social networking activity has opened the door to the misuse and abuse of personal information through identity theft, cyber stalking, and undesirable screenings by prospective employers. Behavioral advertising programs have also misused personal information available on social networking sites. Society is now facing an important question: what level of privacy should be expected and required within the social networking environment
Facebook© goes to college: using social networking tools to support students undertaking teaching practicum
No full textThe impact of Web 2.0 and social networking tools on education has been much commented on. Teachers need to consider how to meet the needs of their students utilising Web 2.0 and other social networking tools. However, tertiary institutions are beginning to recognise that the currently enrolled undergraduate student body is also increasingly Web 2.0 proficient. The focus of undergraduate education degrees has primarily been the use of Web 2.0 tools to teach future school students. However, institutions are now realising that these same tools can be used to create pedagogically sound learning environments for pre-service teachers. This paper will explore the use of social networking tools, such as Facebook©, to support students undertaking teaching practicum. It will introduce a project that involved a cohort of business education students currently enrolled in education degrees at Queensland University of Technology. These students were habitual users of Facebook©, and a group page was created to examine their experiences and behaviours during their teaching practicum placements. This paper will suggest how the digital behaviours and habits of students enrolled in this course may be used in developing supportive tools that can be harnessed during practicum periods
Comparative Risk Predictions of Second Cancers After Carbon-Ion Therapy Versus Proton Therapy
Get PDFPurpose This work proposes a theoretical framework that enables comparative risk predictions for second cancer incidence after particle beam therapy for different ion species for individual patients, accounting for differences in relative biological effectiveness (RBE) for the competing processes of tumor initiation and cell inactivation. Our working hypothesis was that use of carbon-ion therapy instead of proton therapy would show a difference in the predicted risk of second cancer incidence in the breast for a sample of Hodgkin lymphoma (HL) patients. Methods and Materials We generated biologic treatment plans and calculated relative predicted risks of second cancer in the breast by using two proposed methods: a full model derived from the linear quadratic model and a simpler linear-no-threshold model. Results For our reference calculation, we found the predicted risk of breast cancer incidence for carbon-ion plans-to-proton plan ratio, , to be 0.75 ± 0.07 but not significantly smaller than 1 (P=.180). Conclusions Our findings suggest that second cancer risks are, on average, comparable between proton therapy and carbon-ion therapy

Coco Rebecca Edogamhe: A Very Ordinary Girl
Get PDFThe work of Coco Rebecca Edogamhe (born 2001) is unique and relevant case study due to three interdependent factors: her young age and short acting experience, which allow us to observe the construction of professional narratives and practices from scratch; her debut in a leading role without prior acting training, which led her to interpret the set as a school; her identity as an Italian of Afro-descent, which places her at the centre of the debate on diversity and representation. While acknowledging her exceptional profile, she also makes a constant shift towards the notion of 'ordinary', proposing a nuanced and everyday model of celebrity, suitable for both television and digital media. Crucial to all this was the casting process, the debut during the Covid-19 pandemic, and her mirroring in the part of summer in 'Summertime' (Netflix 2020-2022). In this essay, press interviews and an in-depth dialogue between the author and the actress will interact diachronically to capture the main trajectories through which Edogamhe negotiated her public identity and began to build her professional culture

Best Management Practices for Invasive Phragmites Control
Get PDFThe invasion of European Phragmites australis in North America has altered resident species plant assemblages in wetlands and created large monotypic patches. As a response, North American land managers control this invasive species through a combination of herbicide (often glyphosate-based) and mechanical treatments. The impact of glyphosate herbicides and the density of P. australis patches on wetland seedbanks remains unclear, and the mechanical removal of P. australis biomass requires appropriate disposal to avoid further spreading the invasion. I tested the effect of the glyphosate herbicide WeatherMAX® and examined the effect of P. australis stem density on the number and richness of germinating seeds in wetland seedbanks. I also examined the utility of burial as a simple disposal method for P. australis biomass during excavation projects. I found that neither the use of glyphosate herbicide nor the density of P. australis stems significantly affected the number or richness of germinated seeds. Additionally, I observed that the application of herbicide prior to P. australis seed set can reduce the number of viable P. australis seeds added to the local seedbank. After testing the burial method with a mesocosm study, no regrowth of P. australis was observed in units buried 0.7 m or more. My results indicate that a viable seedbank survives herbicide application and high density P. australis invasions. Although my study suggests that 0.7 m is a sufficient burial depth, I recommend 1 m be the minimum burial depth in practice to provide a margin of safety that reflects the invasive potential of P. australis. My research contributes to the body of work related to the control and disposal of P. australis, and the restoration of areas that P. australis has invaded
"He hath Mingled with the Ungodly": The Life of Simeon Solomon After 1873, with a Survey of the Extant Works
Get PDFThis thesis focuses on the life and work of the marginalized British Pre-Raphaelite and Aesthetic homosexual Jewish painter Simeon Solomon (1840-1905) after 1873.This year was fundamental in the artist’s professional and personal life, because it is the year that he was arrested for attempted sodomy charges in London.
The popular view that has been disseminated by the early historiography of Solomon, since before and after his death in 1905, has been to claim that, after this date, the artist led a life that was worthless, both personally and artistically. It has also asserted that this situation was self-inflicted, and that, despite the consistent efforts of his family and friends to return him to the conventions of Victorian middle-class life, he resisted, and that, this resistant was evidence of his ‘deviancy’.
Indeed, for over sixty years, the overall effect of this early historiography has been to defame the character of Solomon and reduce his importance within the Aesthetic movement and the second wave of Pre-Raphaelitism. It has also had the effect of relegating the work that he produced after 1873 to either virtual obscurity or critical censure. In fact, it is only recently that a revival of interest in the artist has gained momentum, although the latter part of his life from 1873 has still remained under-researched and unrecorded.
Therefore, the function of this thesis is to re-evaluate Solomon’s life after his arrest in 1873 and reveal what actually happened to the artist during the final thirty-three years of his life. It does this primarily through a unique study and examination of newly identified archival documents and information. By examining, in particular, the original nineteenth-century records that relate to his arrest in London, and those that record a virtually unknown arrest in Paris in 1874, and putting this in the context of nineteenth-century sodomy law and male homosexual society, it is possible to re-consider Solomon’s previously misunderstood resistance to sexual and societal rehabilitation. It makes use of a new critical understanding, which now suggests the non-repentance of the previously seen tragic figure of the homosexual male in Victorian society, which was promoted in part by the Oscar Wilde trials of 1895. The study of the detail of Solomon’s later life within this thesis will support these new ideas by promoting the suggestion of the artist as self-consciously queer and unapologetic.
In addition, this thesis includes, for the first time, a survey of Solomon’s works produced after 1873, which help to provide an approximation of how active Solomon was artistically; suggest what kind of media he was using during certain periods; record who was continuing to buy Solomon’s work at this time, and to make the images of Solomon’s extant work available to future researchers. These extant images appear in Volume II of this thesis
Brill-Noether-type theorems with a movable ramification point
Get PDFThesis (Ph. D.)--Massachusetts Institute of Technology, Dept. of Mathematics, 2007.This electronic version was submitted by the student author. The certified thesis is available in the Institute Archives and Special Collections.Includes bibliographical references (p. 79-81).The classical Brill-Noether theorems count the dimension of the family of maps from a general curve of genus g to non-degenerate curves of degree d in projective space Pr. These theorems can be extended to include ramification conditions at fixed general points. This thesis deals with the problem of imposing a ramification condition at an unspecified point. We solve the problem completely in dimension 1, prove a closed-form existence criterion and a finiteness result in dimension 2, and provide an existence test and bound the dimension of the family in the general case.by Rebecca C.
