Business school techspectations Technology in the daily lives and educational experiences of business students
No full textBusiness School Techspectations is the second in a series of reports based on research by the DCU Leadership, Innovation and Knowledge Research Centre (LInK) at DCU Business School. With its roots in an Irish business school, it is no surprise that LInK’s mission is to strengthen the competitiveness, productivity, innovation and entrepreneurial capacity of the Irish economy. Ireland’s next generation transformation will be enabled by information and communication technologies (ICT) and digital participation by members of Irish society. As a university research centre we have an important role to play in supporting education, industry and government to accelerate this transformation

Implementing the SCAN language by neural networks
No full textThe real-time encryption of pictures is an important subject for many applications, e.g. television broadcast stations, network security, etc. The paper shows how the previously introduced SCAN encryption method can be easily implemented using binary neural network autoassociative memory
On the question of the calculation of migration volumes in ionic crystals
No full textThe migration volume vm consists of two contributions vms= - T(∂sm/∂P)|T and vhm = (∂hm/∂P)|T where ∂m, hm denote the migration entropy and enthalpy. By analysing the recent experimental data of Andeen, Hayden and Fontanella (1980) on SrF2 + Er+3, obtained by dielectric-loss techniques under various pressures, the term vsm is found to be a considerable contribution t o vm. At 330 K the ratio|vsm|vhm is 23%. Further the compressibility ∼m of the migration volume is found to exceed the bulk compressibility K by one order of magnitude. The application of a recent macroscopic model proposed by Varotsos and Alexopoulos (1978) not only explains that ∼m is appreciably larger than but it also leads t o a value of vsm/vhm appreciably different than zero. The common disagreement between the ‘static lattice’ calculations of vm and experiments lies in the fact that the contribution cannot be neglected. © 1980 Taylor & Francis Group, LLC
Effect of corrosion-induced hydrogen embrittlement and its degradation impact on tensile properties and fracture toughness of (Al-Cu-Mg) 2024 alloy
No full textAbstractIn the present work, the effect of artificial ageing of AA2024-T3 on the tensile mechanical properties and fracture toughness degradation due to corrosion exposure will be investigated. Tensile and fracture toughness specimens were artificially aged to tempers that correspond to Under-Ageing (UA), Peak-Ageing (PA) and Over-Ageing (OA) conditions and then were subsequently exposed to exfoliation corrosion environment. The corrosion exposure time was selected to be the least possible according to the experimental work of Alexopoulos et al. (2016) so as to avoid the formation of large surface pits, trying to simulate the hydrogen embrittlement degradation only. The mechanical test results show that minimum corrosion-induced decrease in elongation at fracture was achieved for the peak-ageing condition, while maximum was noticed at the under-ageing and over-ageing conditions. Yield stress decrease due to corrosion is less sensitive to tempering; fracture toughness decrease was sensitive to ageing heat treatment thus proving that the S΄ particles play a significant role on the corrosion-induced degradation
The Liturgical Book of the Oktoechos. Function, Forms, and Manuscript Tradition
No full textThis chapter offers a detailed investigation into the liturgical book known as the Oktoechos within the Byzantine tradition, focusing on its function, structure, and manuscript history. The Author clarifies the multiple meanings of the term "oktoechos" in Byzantine sources, distinguishing between the musical eight-mode system, the weekly liturgical cycle, and the book itself. The study explores the evolution of the Oktoechos from its early roots in the Jerusalem liturgical tradition, particularly through Georgian and Greek sources such as the Old and New Tropologion. The work highlights the interplay between the Oktoechos and other liturgical books like the Menaion, Triodion, and Pentekostarion, and traces the contribution of major hymnographers including John of Damascus and Andrew of Crete. Special attention is given to terminological ambiguities, manuscript variants, and regional adaptations. Overall, the chapter presents a nuanced reconstruction of the development and standardization of this central Byzantine liturgical book
Socioeconomic status and anxiety as predictors of antidepressant treatment response and suicidal ideation in older adults.
No full textBACKGROUND: Separate reports from the maintenance treatment for late-life depression (MTLD) trials have shown that low socioeconomic status (SES) and anxiety symptoms at the time of treatment initiation predict lower levels of response to antidepressant treatment and higher levels of suicidal ideation in older adults. AIM: To determine whether SES and anxiety independently contribute to worse treatment outcomes, as indicated by persistence of depressive symptoms during treatment and the persistence of suicidal ideation. Consistent with prior evidence that sociodemographic factors and clinical history are both prognostic of depression treatment efficacy, we hypothesized that SES and pre-existing anxiety symptoms will both predict lower levels of response to treatment and higher levels of suicidal ideation. METHOD: Secondary analyses of data from the MTLD trials. RESULTS: Regression analyses which controlled for comorbid anxiety indicated that residents of middle- and high-income census tracts were more likely to respond to treatment (HR, 1.63; 95%CI, 1.08-2.46) and less likely to report suicidal ideation during treatment (OR, 0.51; 95%CI, 0.28-0.90) than residents of low income census tracts. The same regression models indicated that pre-existing anxiety symptoms were independently related to lower treatment response (HR, 0.73; 95%CI, 0.60-0.89) and higher risk of suicidal ideation (OR, 1.45; 95%CI, 0.98-2.14). CONCLUSION: These findings demonstrate the importance of treating anxiety symptoms during the course of treatment for late-life depression and, at the same time, addressing barriers to treatment response related to low SES
Read All About it!! What happens following a technology shock?
No full textExisting indicators of technical change are plagued by shortcomings. I present here new measures based on books published in the field of technology that resolve many of these problems and use them to identify the impact of technology shocks on economic activity. They are positively linked to changes in R&D and scientific knowledge and capture the new technologies' commercialization dates. Changes in information technology are found to be important sources of economic fluctuations in the post-WWII period and total factor productivity, investment and, to a lesser extent, labor are all shown to increase following a positive technology shock.business cycles, technical change, information technologies
