An Examination of Broadening the Engineering Curriculum in Ireland

Short Abstract: This talk will explore whether and how undergraduate engineering programs in Ireland broaden the education of students through the inclusion of non-core engineering content, such as business subjects, in their curriculum in order to develop critical thinking skills and self-knowledge of what it means to be an engineer. Full Abstract: The goal of the paper is to provide a commentary on the level of interaction between business faculty and engineering faculty, in the design and delivery of engineering programs, and the results of that interaction. To this end a taxonomy of engineering enlightenment is proposed, and this is used to discuss evidence of broadening within Irish engineering curricula. We will explore how undergraduate engineering programs in Ireland broaden the education of students through the inclusion of non-core engineering content, such as business subjects, in their curriculum in order to develop critical thinking skills and self-knowledge of what it means to be an engineer. The approach adopted reviews all relevant engineering degree programs in Ireland, based on their publicly available program information; examines the accreditation reports for these same programs; and then surveys business deans to examine whether the business school is involved in the education of engineering students in the institution or university. A number of hybrid engineering programs of study are also explored, and their apparent strengths discussed, including hybridity limits, with a focus on one particular hybrid program within DIT

Conventional versus highly cross-linked polyethylene in primary total knee replacement : a comparison of revision rates using data from the National Joint Registry for England, Wales, and Northern Ireland

There is evidence to support the use of highly cross-linked polyethylene (HXLPE) in patients undergoing total hip arthroplasty. However, the benefits for those undergoing total knee arthroplasty are uncertain, with conflicting reports based on previous cohort analyses. The purpose of the present study was to compare the revision rates following primary total knee arthroplasty with use of HXLPE as compared with conventional polyethylene (CPE) using data from the National Joint Registry (NJR) for England, Wales and Northern Ireland. We performed a retrospective analysis of primary total knee arthroplasties recorded in the NJR from 2003 to 2014. Cobalt-chromium (CoCr)-CPE and CoCr-HXLPE bearing surfaces were compared using all-cause revision, aseptic revision, and septic revision as end points. Survival analyses were conducted using rates per 100 years observed, Kaplan-Meier survival estimates, and Cox regression hazard ratios (HRs) adjusted for age, sex, American Society of Anesthesiologists (ASA) classification, body mass index (BMI), lead surgeon grade, and implant constraint. Secondary analyses compared the most commonly used HXLPEs (Zimmer Prolong, DePuy XLK, and Stryker X3) against CPE for the 3 most common total knee arthroplasty systems (NexGen, PFC Sigma, and Triathlon). In the present study of 550,658 total knee arthroplasties, the unadjusted aseptic revision rates were significantly lower following procedures performed with CPE (n = 513,744) as compared with those performed with HXLPE total knee replacements (n = 36,914) (0.29 [95% confidence interval (CI), 0.28 to 0.30] compared to 0.38 [95% CI, 0.35 to 0.42], p 35 kg/m, the "second-generation" Stryker X3 HXLPE demonstrated significantly better survival than its respective CPE, with CPE having an HR of 2.6 (95% CI, 1.2 to 5.9) (p = 0.02). Alternative bearings are marketed as having improved wear properties over traditional CoCr-CPE. This registry-based analysis demonstrated no overall survival benefit of HXLPE after a maximum duration of follow-up of 12 years. Because of their increased cost, the routine use of HXLPE bearings may not be justified. However, they may have a role in specific "higher demand" groups such as patients 35 kg/m.

Transcoding Kant: Kracauer's Weimar Marxism and after

This is the author's accepted manuscript. The final published article is available from the link below. Copyright @ Koninklijke Brill NV, Leiden, 2013.Kracauer’s rehabilitation in the 1990s sidelined his Marxist framework of the middle-to-late Weimar era in favour of the then still dominant if decaying paradigms of poststructuralism and postmodernism. It was also silent on the relationship between Kant and Marxism in Kracauer’s work. This essay addresses these weaknesses by arguing that Kracauer transcoded the structure of Kant’s ‘problematic’ around reification into a Marxist framework in the middle-to-late Weimar period. The essay considers how Kracauer conceived the mass ornament (photography and film especially) as a site of reification and critical pedagogy. It explores his strategies of de-reification and their overlap with Walter Benjamin and the ruptures and continuities between the radical Weimar work and his later Theory of Film. The essay argues that the Theory of Film can be better understood as a transcoding of Kant’s philosophy of the aesthetic in the third Critique into the film camera itself, although the Marxian framework of the Weimar period is now considerably attenuated

The effect of high dose antibiotic impregnated cement on rate of surgical site infection after hip hemiarthroplasty for fractured neck of femur : a protocol for a double-blind quasi randomised controlled trial

Background: Mortality following hip hemiarthroplasty is in the range of 10-40% in the first year, with much attributed to post-operative complications. One such complication is surgical site infection (SSI), which at the start of this trial affected 4.68% of patients in the UK having this operation. Compared to SSI rates of elective hip surgery, at less than 1%, this figure is elevated. The aim of this quasi randomised controlled trial (RCT) is to determine if high dose antibiotic impregnated cement can reduce the SSI in patients at 12-months after hemiarthroplasty for intracapsular fractured neck of femur. Methods: 848 patients with an intracapsular fractured neck of femur requiring a hip hemiarthroplasty are been recruited into this two-centre double-blind quasi RCT. Participants were recruited before surgery and quasi randomised to standard care or intervention group. Participants, statistician and outcome assessors were blind to treatment allocation throughout the study. The intervention consisted of high dose antibiotic impregnated cement consisting of 1 gram Clindamycin and 1 gram of Gentamicin. The primary outcome is Health Protection Agency (HPA) defined deep surgical site infection at 12 months. Secondary outcomes include HPA defined superficial surgical site infection at 30 days, 30 and 90-day mortality, length of hospital stay, critical care stay, and complications. Discussion: Large randomised controlled trials assessing the effectiveness of a surgical intervention are uncommon, particularly in the speciality of orthopaedics. The results from this trial will inform evidence-based recommendations for antibiotic impregnated cement in the management of patients with a fractured neck of femur undergoing a hip hemiarthroplasty. If high dose antibiotic impregnated cement is found to be an effective intervention, implementation into clinical practice could improve long-term outcomes for patients undergoing hip hemiarthroplasty

Antibiotic-loaded bone cement is associated with a lower risk of revision following primary cemented total knee arthroplasty

Aims Antibiotic-loaded bone cements (ALBCs) may offer early protection against the formation of bacterial biofilm after joint arthroplasty. Use in hip arthroplasty is widely accepted, but there is a lack of evidence in total knee arthroplasty (TKA). The objective of this study was to evaluate the use of ALBC in a large population of TKA patients. Materials and Methods Data from the National Joint Registry (NJR) of England and Wales were obtained for all primary cemented TKAs between March 2003 and July 2016. Patient, implant, and surgical variables were analyzed. Cox proportional hazards models were used to assess the influence of ALBC on risk of revision. Body mass index (BMI) data were available in a subset of patients. Results Of 731 214 TKAs, 15 295 (2.1%) were implanted with plain cement and 715 919 (97.9%) with ALBC. There were 13 391 revisions; 2391 were performed for infection. After adjusting for other variables, ALBC had a significantly lower risk of revision for any cause (hazard ratio (HR) 0.85, 95% confidence interval (CI) 0.77 to 0.93; p < 0.001). ALBC was associated with a lower risk of revision for all aseptic causes (HR 0.85, 95% CI 0.77 to 0.95; p < 0.001) and revisions for infection (HR 0.84, 95% CI 0.67 to 1.01; p = 0.06). The results were similar when BMI was added into the model, and in a subanalysis where surgeons using only ALBC over the entire study period were excluded. Prosthesis survival at ten years for TKAs implanted with ALBC was 96.3% (95% CI 96.3 to 96.4) compared with 95.5% (95% CI 95.0 to 95.9) in those implanted with plain cement. On a population level, where 100 000 TKAs are performed annually, this difference represents 870 fewer revisions at ten years in the ALBC group. Conclusion After adjusting for a range of variables, ALBC was associated with a significantly lower risk of revision in this registry-based study of an entire nation of primary cemented knee arthroplasties. Using ALBC does not appear to increase midterm implant failure rates

Spectral cinema from a phantom state: film aesthetics and the politics of identity in Divided Heaven and Solo Sunny

In this essay I draw on close textual analysis to consider the interface between film aesthetics and the politics of identity in Konrad Wolf’s Der geteilte Himmel / Divided Heaven (1964) and Solo Sunny (1979). Both films focus on women who have to confront painful processes of self realisa-tion in specifically East German contexts. They also show Wolf and his collaborators working in two very different modes, from a nouvelle vague-inspired mix of location shooting and self-conscious formal artifice to a more laconic style and mobile camera that borrow from documentary aesthetics. Viewed from the perspective of today, the films resist the reductive stereotyping of what Christa Wolf in 1991 called the 'phantom' East Germany, and offer a more productive haunting. As living ghosts in the post-reunification era, they are a reminder of the necessity of remembering, and so confound both a negative 'master narrative' of the GDR and a collective amnesia with no interest in this history

Reclaiming heritage: colourization, culture wars and the politics of nostalgia

This article considers the discursive continuities between a specifically liberal defence of cultural patrimony, evident in the debate over film colourization, and the culture war critique associated with neo-conservatism. It examines how a rhetoric of nostalgia, linked to particular ideas of authenticity,canonicity and tradition,has been mobilized by the right and the left in attempts to stabilize the confguration and perceived transmission of American cultural identity. While different in scale, colourization and multiculturalism were seen to create respective (postmodern) barbarisms against which defenders of culture, heritage and good taste could unite. I argue that in its defence of the ‘classic’ work of art, together with principles of aesthetic distinction and the value of cultural inheritance,the anti-colourization lobby helped enrich and legitimize a discourse of tradition that, at the end of the 1980s, was beginning to reverberate powerfully in the conservative challenge to a ‘crisis’ within higher education and the humanities. This article attempts to complicate the contemporary politics of nostalgia, showing how a defence of cultural patrimony has distinguished major and minor culture wars, engaging left and right quite differently but with similar presuppositions
