Construction Innovation Futures - Industry and Environmental Opportunities.

During the next two decades global construction investment will top $100 trillion (US). New directions in construction innovation will be driven by industry to address challenges in skills, environmental regulations and maximise the benefits of low carbon building systems. Growth productivity catalysts such as offsite construction, higher BIM levels and multi-skill operatives will be instrumental contributors in achieving some of these aims. The increasing use of timber architecture across domestic, public and commercial buildings also opens new pathways. This event will discuss some of the key changes taking place in the UK and parallels with Hong Kong’s ambitions towards delivering a sustainable legacy in this sector.

'Expanding Horizons': investigating the Glasgow 2014 legacy for young people in the East End of Glasgow

The recent staging of Glasgow 2014 drew universal praise as the ‘Best Games Ever’. Yet the substantial undertaking of hosting the Commonwealth Games (CWG) was sold to the nation as more than just eleven days of sporting spectacle and cultural entertainment. Indeed, the primary strategic justification offered by policymakers and city leaders was the delivery of a bundle of positive and enduring benefits, so-called ‘legacy’. This ubiquitous and amorphous concept has evolved over time to become the central focus of contemporary hosting bids, reflecting a general public policy shift towards using major sporting mega events as a catalyst to generate benefits across economic, environmental and social dimensions, on a scale intended to be truly transformative. At the same time, the academy has drawn attention to the absence of evidence in support of the prevailing legacy rhetoric and raised a number of sociological concerns, not least the socially unequitable distribution of purported benefits. This study investigated how young people living in the core hosting zone related to, and were impacted upon, by the CWG and its associated developments and activities with reference to their socio-spatial horizons, the primary outcome of interest. An ‘ideal world’ Logic Model hypothesised that four mechanisms, identified from official legacy documents and social theories, would alter young people’s subjective readings of the world by virtue of broadening their social networks, extending their spatial boundaries and altering their mind sets. A qualitative methodology facilitated the gathering of situated and contextualised accounts of young people’s attitudes, perceptions, beliefs and behaviours relating to Glasgow 2014. In-depth interviews and focus groups were conducted before and after the Games with 26 young people, aged 14-16 years, at two schools in the East End. This approach was instrumental in privileging the interests of people ‘on the ground’ over those of city-wide and national stakeholders. The findings showed that young people perceived the dominant legacy benefit to be an improved reputation and image for Glasgow and the East End. Primary beneficiaries were identified by them as those with vested business interests e.g. retailers, restaurateurs, and hoteliers, as well as national and local government, with low expectations of personal dividends or ‘trickle down’ benefits. Support for Glasgow 2014 did not necessarily translate into individual engagement with the various cultural and sporting activities leading up to the CWG, including the event itself. The study found that young people who engaged most were those who had the ability to ‘read’ the opportunities available to them and who had the social, cultural and economic capital necessary to grasp them, with the corollary that those who might have gained most were the least likely to have engaged with the CWG. Doubts articulated by research participants about the social sustainability of Glasgow 2014 underscored inherent tensions between the short-lived thrill of the spectacle and the anticipated longevity of its impacts. The headline message is that hosting sporting mega events might not be an effective means of delivering social change. Aspirant host cities should consider more socially equitable alternatives to sporting mega events prior to bidding; and future host cities should endeavour to engage more purposefully with more young people over longer time frames.

Effects of organic fertilizers on the vegetative, nutritional, and productive parameters of blueberries ‘Corona’, ‘Legacy’, and ‘Liberty’

Organic farming does not allow using certain inputs, such as N, which differ in nutrient release rates and dynamics. To evaluate the effect of different organic fertilizers on the vegetative, nutritional, and productive parameters of blueberries ( Vaccinium corymbosum L.), a pot experiment was conducted in three consecutive seasons in a sandy soil of south-central Chile using ‘Corona’, ‘Legacy’ and ‘Liberty’. The following fertilizers were evaluated: compost (CM), Purely Grow (PG), Purely Lysine (PL), Fertil (F), blood meal (BM), lupine meal (LM), along with a control treatment without fertilization (C) and two conventional treatments with urea (CF) and sodium nitrate (S). Results indicate that vegetative growth and leaf N concentration prior to senescence were different among cultivars in the three evaluated seasons. The highest leaf N concentration was recorded in ‘Corona’ followed by ‘Legacy’ and ‘Liberty’ while levels tended to increase in the seasons. Quick-release N sources had greater effects on these parameters but with differences among cultivars. Fruit yield and weight were higher in ‘Corona’ followed by ‘Legacy’ and ‘Liberty’. Fruit yield was generally higher when using LM and F and showed no effect on fruit weight. Leaf chlorophyll content was higher in ‘Corona’ followed by ‘Legacy’ and ‘Liberty’, which increased when using CF, LM, BM, and PG. Finally, the organic fertilizer and blueberry cultivar that obtained the highest values for most of the evaluated parameters were LM and Corona, respectively.

Alzheimer’s electroencephalogram event scalp and source localization

Alzheimer’s disease is the most common cause of dementia which causes a progressive and irreversible impairment of several cognitive functions. The aging population has been increasing significantly in recent decades and this disease affects mainly the elderly. Its diagnostic accuracy is relatively low and there is not a biomarker able to detect AD without invasive tests. Despite the progress in better understanding the disease there remains no prospect of cure at least in the near future. The electroencephalogram (EEG) test is a widely available technology in clinical settings. It may help diagnosis of brain disorders, once it can be used in patients who have cognitive impairment involving a general decrease in overall brain function or in patients with a located deficit. This study is a new approach to improve the scalp localization and the detection of brain anomalies (EEG temporal events) sources associated with AD by using the EEG.

Modelling human behaviour and event detection from videos

Automatic analysis of human behaviour in large collections of videos is gaining interest, even more so with the advent of file sharing sites such as YouTube. However, challenges still exist owing to several factors such as inter- and intra-class variations, cluttered backgrounds, occlusion, camera motion, scale, view and illumination changes. This research focuses on modelling human behaviour for action recognition in videos. The developed techniques are validated on large scale benchmark datasets and applied on real-world scenarios such as soccer videos. Three major contributions are made. The first contribution is in the area of proper choice of a feature representation for videos. This involved a study of state-of-the-art techniques for action recognition, feature extraction processing and dimensional reduction techniques so as to yield the best performance with optimal computational requirements. Secondly, temporal modelling of human behaviour is performed. This involved frequency analysis and temporal integration of local information in the video frames to yield a temporal feature vector. Current practices mostly average the frame information over an entire video and neglect the temporal order. Lastly, the proposed framework is applied and further adapted to real-world scenario such as soccer videos. A dataset consisting of video sequences depicting events of players falling is created from actual match data to this end and used to experimentally evaluate the proposed framework.

Investigating output accuracy for a discrete event simulation model and an agent based simulation model

In this paper, we investigate output accuracy for a Discrete Event Simulation (DES) model and Agent Based Simulation (ABS) model. The purpose of this investigation is to find out which of these simulation techniques is the best one for modelling human reactive behaviour in the retail sector. In order to study the output accuracy in both models, we have carried out a validation experiment in which we compared the results from our simulation models to the performance of a real system. Our experiment was carried out using a large UK department store as a case study. We had to determine an efficient implementation of management policy in the store’s fitting room using DES and ABS. Overall, we have found that both simulation models were a good representation of the real system when modelling human reactive behaviour.

Business Process Management and Process Mining within a Real Business Environment: An Empirical Analysis of Event Logs Data in a Consulting Project

Il presente elaborato esplora l’attitudine delle organizzazioni nei confronti dei processi di business che le sostengono: dalla semi-assenza di struttura, all’organizzazione funzionale, fino all’avvento del Business Process Reengineering e del Business Process Management, nato come superamento dei limiti e delle problematiche del modello precedente. All’interno del ciclo di vita del BPM, trova spazio la metodologia del process mining, che permette un livello di analisi dei processi a partire dagli event data log, ossia dai dati di registrazione degli eventi, che fanno riferimento a tutte quelle attività supportate da un sistema informativo aziendale. Il process mining può essere visto come naturale ponte che collega le discipline del management basate sui processi (ma non data-driven) e i nuovi sviluppi della business intelligence, capaci di gestire e manipolare l’enorme mole di dati a disposizione delle aziende (ma che non sono process-driven). Nella tesi, i requisiti e le tecnologie che abilitano l’utilizzo della disciplina sono descritti, cosi come le tre tecniche che questa abilita: process discovery, conformance checking e process enhancement. Il process mining è stato utilizzato come strumento principale in un progetto di consulenza da HSPI S.p.A. per conto di un importante cliente italiano, fornitore di piattaforme e di soluzioni IT. Il progetto a cui ho preso parte, descritto all’interno dell’elaborato, ha come scopo quello di sostenere l’organizzazione nel suo piano di improvement delle prestazioni interne e ha permesso di verificare l’applicabilità e i limiti delle tecniche di process mining. Infine, nell’appendice finale, è presente un paper da me realizzato, che raccoglie tutte le applicazioni della disciplina in un contesto di business reale, traendo dati e informazioni da working papers, casi aziendali e da canali diretti. Per la sua validità e completezza, questo documento è stata pubblicato nel sito dell'IEEE Task Force on Process Mining.

Lower Aptian Comparative Stratigraphy of the Basco-Cantabrian Region (Spain) and Eastern Cordillera (Colombia): implications for local factors in the depositional record of Oceanic Anoxic Event 1a (OAE-1a)

An important episode of carbon sequestration, Oceanic Anoxic Event 1a (OAE-1a), characterizes the Lower Aptian worldwide, and is mostly known from deeper-water settings. The present work of two Lower Aptian deposits, Madotz (N Spain) and Curití Quarry (Colombia), is a multiproxy study that includes fossil assemblages, microfacies, X-ray diffraction bulk and clay mineralogy, elemental analyses (major, minor, trace elements), Rock-Eval pyrolysis, biomarkers, inorganic and organic carbon content, and stable carbon isotopes. The results provide baseline evidence of the local and global controlling environmental factors influencing OAE-1a in shallow-water settings. The data also improve our general understanding of the conditions under which organic-carbon-rich deposits accumulate. The sequence at Madotz includes four intervals (Unit 1; Subunits 2a, 2b and 2c) that overlap the times prior to, during and after the occurrence of OAE-1a. The Lower Unit 1(3m thick) is essentially siliciclastic, and Subunit 2a (20m) contains Urgonian carbonate facies that document abruptly changing platform conditions prior to OAE-1a. Subunit 2b (24.4 m) is a mixed carbonate-siliciclastic facies with orbitolinid-rich levels that coincides with OAE-1a δ13C stages C4-C6, and is coeval with the upper part of the Deshayesites forbesi ammonite zone. Levels with pyrite and the highest TOC values (0.4-0.97%), interpreted as accumulating under suboxic conditions, and are restricted to δ13C stages C4 and C5. The best development of the suboxic facies is at the level representing the peak of the transgression. Subunit 2c, within δ13C stage C7, shows a return of the Urgonian facies. The 23.35-m section at Curití includes a 6.3-m interval at the base of the Paja Formation dominated by organic-rich marlstones and shales lacking benthic fossils and bioturbation, with TOC values as high as 8.84%. The interval overlies a level containing reworked and phosphatized assemblages of middle Barremian to lowest Aptian ammonites. The range of values and the overall pattern of the δ13Corg (-22.05‰ to -20.47‰) in the 6.3m-interval is comparable with Lower Aptian δ13C stage C7. Thus, conditions of oxygen depletion at this site also occurred after Oceanic Anoxic Event-1a, which developed between carbon isotope stages C3 and C6. Both sites, Madotz and Curití, attest to the importance of terrigenous and nutrient fluxes in increasing OM productivity that led to episodic oxygen deficiency.

Jointly event extraction and visualization on Twitter via probabilistic modelling

Event extraction from texts aims to detect structured information such as what has happened, to whom, where and when. Event extraction and visualization are typically considered as two different tasks. In this paper, we propose a novel approach based on probabilistic modelling to jointly extract and visualize events from tweets where both tasks benefit from each other. We model each event as a joint distribution over named entities, a date, a location and event-related keywords. Moreover, both tweets and event instances are associated with coordinates in the visualization space. The manifold assumption that the intrinsic geometry of tweets is a low-rank, non-linear manifold within the high-dimensional space is incorporated into the learning framework using a regularization. Experimental results show that the proposed approach can effectively deal with both event extraction and visualization and performs remarkably better than both the state-of-the-art event extraction method and a pipeline approach for event extraction and visualization.

Review of Two Issues at the Long-Term Commitment Facilities, Department of Juvenile Justice: 1)Safety Threat to Employees & Juveniles; and 2)Event Reporting Process Integrity Allegations

The Legislative Oversight Committee of the South Carolina House of Representatives, referred allegations pertaining to the Department of Juvenile Justice (DJJ) which were generated during its ongoing oversight study of DJJ. Specifically, the safety issues focused on lack of control; lack of trust; and lack of adequate staffing. This review’s scope and objectives were: Investigate specific complainant allegations of DJJ employees underreporting, misreporting, or destroying ERs; Review the efficiency and effectiveness of DJJ’s event reporting process and follow-up on anomalies or potential patterns of systemic underreporting, misreporting, or missing ERs; and Assess juvenile and employee safety conditions through interviewing a cross-section of relevant employees, record review, and possibly an employee survey.

The Legacy of Frankenstein’s Creature: Monstrosity and Female Grotesque in Mary Shelley, Angela Carter and Jeanette Winterson

This English Literature thesis (European PhD EDGES – Women’s and Gender Studies – 34th cycle) is an investigation into the representation of the monstrous body according to the British writers Mary Shelley, Angela Carter and Jeanette Winterson. The main objective is to observe how the representation of the categories of monstrous, abject and grotesque in Western cultural imagination have been influenced across time and literary genres. In the novels of Shelley, Carter and Winterson, the monstrous subject is configured as an alternative to the anthropocentric ideal embodied by the normative subject, of which Victor Frankenstein is the paradigmatic exponent. Plus, there are places considered anti-topoi within which the monster acquires a situatedness and claims a voice, generating an opposed counter-narrative to the imaginary conveyed by the normative subject. Monstrosity outlined by Shelley in the novels Frankenstein and The Last Man constitutes the starting point of my research, aiming to observe how the discourse of the normative body vs. the anti-normative body intersects with the discourse of the spaces of the centre vs. the spaces of the margin. In Carter's novels The Passion of New Eve and Nights at the Circus, the monstrous female constitutes the embodiment of wills, desires and claims challenging the heteronormative system. The space of otherness in which Carter's monster-woman is confined becomes a possibility of reshaping identity for the Subject, deconstructing the logic of power that moulded her within society. Finally, Winterson creates two monstrous women in Sexing the Cherry and The Passion who move through urban spaces, going from the centre to the margins and testifying to the arbitrariness of the system and its weaknesses. Similarly, in Frankissstein, Winterson recovers Shelley's original novel and transforms it into a parodic and intertextual speculation on the fluidity of identity and the limits of transhumanism.
