description: This report investigates the effects of an increased exploitation of shale gas reserves around the globe and the extent to which it can serve as a low-cost GHG mitigation option. We compare a scenario of global shale gas exploitation with a scenario in which shale gas use is very limited. Both scenarios are modelled with the global techno-economic POLES model and rely on a high regional disaggregation. The effects of shale gas production on the energy market and, consequently, on GHG emissions are analysed in a baseline case without additional climate policy andfor mitigation targets compatible with the 2˚C target. We find that shale gas should not be considered a cheap option to reduce global GHG emissions due to three reasons: the effects of global shale gas availability (a) are small in the short-term, (b) lead to higher baseline GHG emissions for most countries in the long-term due to lower energy prices and (c) result in higher costs of compliance with climate targets.

description: L’apprentissage de compétences en littératie demeure un défi pour plusieurs apprenants, dont les élèves ayant une déficience intellectuelle (DI). La présente recension des écrits scientifiques pointe le peu de recherches auprès d’élèves ayant une DI moyenne à sévère (DI-MS). Cette recension vise à documenter les approches, théories et programmes sur les compétences en littératie (oral, lecture, écriture et intégration numérique). La méthodologie de recension intégrative (Jackson, 1980) est privilégiée. La synthèse critique de sept recherches sur les programmes d’enseignement en littératie a permis de préciser qu’aucune de celles-ci ne traite des volets de l’oral et de l’écriture de texte. Elles ne présentent ni approche ni cadre théorique en lien avec l’acquisition du langage oral et écrit. Les contributions et les limites de ces programmes sont discutées.

Language model pretraining and fine-tuning for emotion classification tasks using Vent data
Creators: name: Francia, Allan
Publisher: name: Macquarie University
Year: 2024
Subjects: classificationCode: 460208
subject: Natural language processing

description: Emotion classification of text data has numerous potential benefits in various applications ranging from assessing the mental health of the community through to understanding customer feedback on products and services. The recent development of transformers for language modelling has raised the benchmark results for numerous tasks in natural language processing. Alongside the performance improvement, the development of transformer models also presented several challenges such as availability of pretraining data, language model size (including parameters), training time and required computing power requirements. This research project determines if there are benefits in pretraining a transformer language model called BERT using emotion specific domain data from a social media platform called Vent. It compares the output of pretraining to just fine-tuning the original model. In doing so it also determines what size is required to pretrain the BERT model to generate reasonable results as well as how the size of pretraining data scales with the results within a constrained computing power budget. This research project also benchmarks its emotion classification results against the multilabel classification GoEmotions project. Although, the pretraining results did not outperform the original BERT models both for the multi-class and multilabel tasks, the results were close.

On the central moments of the linear combinations of multidimensional random variables: a contribution to maximum and minimum values determination
Creators: name: Greco, L.
Publisher: name: Dep. of Statistical Sciences "Paolo Fortunati", Università di Bologna
Year: 2013

description: In the statistical analysis of multivariate distributions, the linear combinations for which the standardized third and fourth moments have their maximum or minimum value may by utilized, for instance, to inquire on robustness, test on multinormality or identify possible outliers or clusters.
In this note some theoretical results are shown widening the concept of a matrix eigenvalue and  eigenvector which are obtained by the author in determining such combinations. There are given explicit solutions for bivariate distributions, while an iterative method is suggested for those of greater dimensions.

Estimation of variance of sample variance in sample random sampling
Creators: name: Herzel, A.
Publisher: name: Dep. of Statistical Sciences "Paolo Fortunati", Università di Bologna
Year: 2013

description: As it is known, the general m.v.u estimator of the variance of sample variance in simple random sampling is given by a linear combination with fixed coefficients of the fourth central moment and the square of the variance observed in the sample. In this paper, the best unbiased estimator is determined when the coefficient are allowed to depend on the moments of the standardized  population. Explicit formulas are given for sapling  with repetition. The results are illustrated on ten theoretical populations of different shape. By means of a simulation exercise it is investigated what happens when in the best estimator population moment, assumed unknown, are substituted by the corresponding sample moments. In the appendix other results concerning the fourth central moment and the square of variance are given.

Maximum entropy: E.T.Jaynes and thereabout
Creators: name: Rosa, R.
Publisher: name: Dep. of Statistical Sciences "Paolo Fortunati", Università di Bologna
Year: 2013

description: The maximum entropy principle for determining probabilities is discussed. Jaynes'program concerning inductive inference and the foundations of statistical mechanics is reviewed and taken as a guide for the present paper. Attention is devoted to the historical and philosophical aspects of classical statistical mechanics, such as the assumption of equal a priori probability of microstates. The alleged subjectivity of entropy in connection with information theory and irreversible processes is also discussed. Finally, the paper deals with the birth of quantum statistics with emphasis to statistical dependence and indistinguishability in the Bose-Einstein counting procedure. The conclusions suggest that the way of counting elementary cases as assumed as equiprobable is an empirical hypothesis rather than the result of a rational a priori analysis supported by principles such as that if indifference or maximum entropy.

Creators: name: Bhadra, Chris Mallika
Publisher: name: Swinburne
Year: 2024

description: This thesis has been primarily devoted to the investigation of three types of newly fabricated multi-dimentional bio-inspired material surfaces. These materials were: commerical purity Grade 2 titanium, black silicon and a three-dimensional poly (vinyl alcohol) (PVA) - Vinyl Pyrrolidone (VP) hydrogel.

The biomimetric and antibacterial titanium and black silicon surfaces produced in this study were shown to possess selective bactericidal activity, and the ability to enhance the attachment and proliferation of primary human fibroblasts. These smart nano-structured surfaces have excellent prospects for biomedical applications.

Optimisation énergétique

description: Cette communication est réalisée dans le cadre d'un projet qui consiste à étudier, modéliser et monitorer les interactions entre une installation aéro-photovoltaïque améliorée et un bâtiment énergétiquement performant afin d'optimiser l'utilisation des ressources renouvelables (électrique et thermique dans le cas de ces panneaux hybrides) en fonction des besoins de ce dernier. Dans le cadre de ce projet, nous avons déjà mis en avant les gains potentiels que nous pourrions obtenir par une intensification passive des échanges par générateur de vorticité dans le chenal des panneaux PV/Ta permettant d'améliorer les échanges thermiques convectifs.  Sur base des résultats de nos études préalables, nous avons développé un module de notre panneau aéro-photovoltaïque dans TRNSYS. Grâce aux simulations thermiques dynamiques (STD), nous étudions les apports d'une installation aéro-photovoltaïque améliorée sur une habitation unifamiliale à faibles besoins en chauffage située dans l'est de la Belgique. Nous comparons les résultats obtenus, tant d'un point de vue de la consommation énergétique que de la production électrique, avec la situation reprenant une installation de panneaux solaires hybrides non améliorés.  Nous présentons également une étude de sensibilité de ces mêmes consommation et production en fonction de la situation géographique, afin de déterminer les régions les plus propices à l'usage de ce type de technologie.
Stochastic and deterministic trend models
Creators: name: Bee Dagum, Estela
name: Dagum, Camilo
Publisher: name: Dep. of Statistical Sciences "Paolo Fortunati", Università di Bologna
Year: 2008

description: In this paper we provide an overview of some trend models formulated for global and local estimation. Global trend models are based on the assumption that the trend or nonstationary mean of a time series can be approximated closely by simple functions of time over the entire span of the series. The most common representation of deterministic and stochastic trend are introduced. In particular, for the former we analyze polynomial and transcendental functions, whereas for the latter we assume that the series from which the trend will be identified follows a homogeneous linear nonstationary stochastic process. Recently more attention has been oriented on the analysis of the short term trend, that includes cyclical fluctuations and is referred to as trend-cycle. At this regard, we analyze the local polynomial regression predictors developed by Henderson (1916) and LOESS due to Cleveland (1979), which are the most widely applied to estimate the short term local trend of seasonally adjusted economic indicators.

description: Camilo Dagum, one of the most prominent and noble person in the fields of Statistics and Economics died on November 5 2005 of an inescapable disease. He had just celebrated his 80th year birthday but still physically strong with great intellectual capacity for the multiple responsibilities called upon him by his prestige and fame. His scientific obligations forced him to travel all around the world, from one scientific meeting to another, in academy and university, where his contributions were always expected, admired, and discussed. During the years his work had become more intense and his projects were projected to a future where only bad luck would stop them. To read one of his pages, to discuss with him, was as to be facing a horizon of ideas and problems, of reality and propositions. Camilo Dagum had been a great mind with a great conscience; his way of living, recent and distant, is a demonstration of freedom of choice, dignity, and truth.

Nationalism and Its Effects On Foreign Economic Policy

Year: 2022
Subjects: subject: Trade
subject: Taiwan
subject: Nationalism
subject: Identity

description: This paper explores the impact that nationalism and national identity have on a state’s foreign economic policies and trade with other countries. In order to understand the impact that nationalism has on trade and foreign economic policy, this paper examines multiple presidential administrations from the Republic of China (Taiwan). Within each administration, this paper analyzes speeches, interviews, and policies to understand how leaders and the public utilize national identity to shape trade and economic relations. The findings of this paper demonstrate that nationalism likely does shape economic and trade policies by diverting trade away from political rivals or countries that conflict with nationalist goals. However, this only holds true when the economy is healthy. When the economy is unhealthy, nationalism has less of an impact on trade, as the direness of the economic situation prevents policies from being selective with where the state’s economic growth comes from.
The D.Currie's test on the long run dynamic properties of the autoregressive-distributed lag models
Creators: name: Binotti, A. M.
Publisher: name: Dep. of Statistical Sciences "Paolo Fortunati", Università di Bologna
Year: 2013

description: A major criticism about the autoregressive-distributed lag (AD) models is that the long run dynamic properties of  such models are often  not sensible and well-determined. These dynamic properties pose particular problems both for practical forecasting and simulation and because economic theory not always leads us to expect the presence of long run dynamic effects.
In a recent paper D. Currie (1981) suggested a  particular test which allows to examine the significance of these long run dynamic effects and to constrains such effects to zero where appropriate.
The main purpose of this paper is to examine this test procedure and to show that it can easily produce dynamic misspecification. Analysing a simple  first degree dynamic model, we are able to prove that the suggested restrictions to test are the same restrictions we test in the COMFAC analysis. We also show the relationship between these two tests in the 'general-to-specific' dynamic specification strategy.

Measuring male and female change of life expectancies in Italy
Creators: name: Gerondi, C.
Publisher: name: Dep. of Statistical Sciences "Paolo Fortunati", Università di Bologna
Year: 2013

description: This paper presents some procedures for the analysis of historical and mortality differential changes by using life expectancies.
Among the indices considered to estimate the pace of mortality of Italian male and female population in the last century, the index of relative change suggested by Arriaga is the most suitable.
In the second part of the paper two methods are outlined to determine the contribution of mortality changes in the various age-groups to total change in life expectancy. One of theme  is founded on decomposition in three components. The two components solution appears the most effective to determine exclusive age contribution.

Comparing inequality measures
Creators: name: Frosini, B. V.
Publisher: name: Dep. of Statistical Sciences "Paolo Fortunati", Università di Bologna
Year: 2013

description: Le misure di diseguaglianza, o concentrazione, esaminate in questo articolo si riferiscono alle distribuzioni del reddito e della ricchezza, visto che per altri problemi (ad esempio concentrazione industriale) sembra siano richiesti requisiti parzialmente contrastanti. Scopo del lavoro è quello di investigare sulle proprietà che una misura di diseguaglianza deve possedere perchè possa essere impiegata su diverse distribuzioni, mantenendo comunque una capacità comparativa.
Un primo passo in questa direzione consiste nell'accettare la comparabilità di più distribuzioni sulla base di un ordinamento parziale delle rispettive curve di Lorenz, che sono indipendenti dalla scala e dalla dimensione della popolazione. Dopo aver stabilito semplici proprietà operative per la comparabilità di misure di disuguaglianza, le medesime proprietà sono state verificate per numerosi indici; è stato anche riconosciuto che alcuni di essi non possono essere normalizzati esattamente tra 0 e 1 -sotto le usuali assunzioni- senza perdere la comparabilità (ad esempio l'indice di Theil e il coefficiente di variazione).
Allo scopo di liberarci in ogni caso dei problemi derivanti dalle diverse numerosità delle popolazioni, sono state seguite due procedure. La prima è basata sull'assunzione di un reddito massimo convenzionale, espresso come k volte il reddito medio. La seconda è più drastica, nel senso che viene fissato in anticipo il numero di "unità aggregate" sulle quali valutare la concentrazione. Per afferrare il reale significato di queste procedure sono state fatte due specie di applicazioni: (a) a tre recenti indagini su redditi individuali, e (b) a unità aggregate ricavate da alcune distribuzioni di Pareto e lognormali.

Examining the nature of educational inclusion for students labelled with a specific learning disability (SLD)
Creators: name: Mosen, Joanne Maree
Publisher: name: Swinburne
Year: 2024

description: This study focused on a group of students with average to above-average intelligence who experience educational barriers due to a Specific Learning Disability. This disability group is misunderstood and currently under-supported in many classrooms throughout the world including in Australia. This can result in an over-representation of individuals with this disability in negative life outcomes such as early school leaving, suicide and criminal behaviour. Findings indicate that accurate awareness of the Specific Learning Disability label improves educational inclusion, self-esteem and the provision of supports aligned with strengths, weaknesses and processing preferences for the estimated 10% of students with this disability.

Response surface modelling of thermo-mechanical fatigue in hot forging

Publisher: name: Dep. of Statistical Sciences "Paolo Fortunati", Università di Bologna

description: Investigation of thermo-mechanical fatigue (TMF) phenomena usually involves complex experimentation and long testing runs, as well as difficulties in specifying and fitting appropriate models. Moreover, the experimental techniques usually consider temperature in the specimen to be constant, or slowly varying, often with a uniform distribution of temperature in the cross section of the specimen but it is not a plausible assumption.
Aimed at extending the investigation to hot forging dies, where the variation of some hundreds of °C is operated in a few seconds and thermal gradient (some tens of °C per mm) is present, the experimental configuration become more complex.
The present paper focuses on a recently proposed experiment for a TMF investigation of hot forging dies where Design of Experiments techniques are used to fit a model for
TMF lives. This study allows to detect which factors are more important in affecting the TMF, to “describe” the relationship between TMF and these factors and to predict TMF lives. Experimental data are analyzed using Response Surface Modelling (RSM) in order to fit an empirical linear model.

description: In this paper we study the family of distributions termed as exponentiated Weibull distribution. The distribution has three parameters (one scale and two shape) and the Weibull distribution and the exponentiated exponential distribution, discussed by Gupta,
et al. (1998), are particular cases of it. The survival function, failure rate and moments of the distributions have been derived using certain special formulas. The behavior of the failure rate has been studied and compared with those of the Weibull and Gamma distributions. The distribution has been fitted to a real life data set and the fit has been found to be very good.

End of the road? Why it might be time to ditch your car
Creators: name: James, Anthony
Publisher: name: Swinburne
Year: 2024

description: The average car is stationary 96% of the time. That's a fairly consistent finding around the world, including in Australia. A car is typically parked at home 80% of the time, parked elsewhere 16% of the time, and on the move just 4% of the time. And that doesn’t include the increasing time we spend at a standstill in traffic. Bill Ford, executive chair of the Ford Motor Company, says we're heading for "global gridlock". And he's not alone in saying we cannot simply keep adding more cars to our roads.
The funny thing is that while we own more cars than ever, we're actually using them less. You might think that's a good thing; that we’re responding to worsening congestion and health, debt and environmental damage by opting to drive fewer kilometres. But the problem is, we're still choking our cities and harming our health, finances and environment by continuing to waste our resources on these increasingly dormant vehicles.

A evolução tecnológica viabilizou novas formas de interação do ser humano, criando uma relação de colaboração e descentralização entre homem e máquina, existindo, assim, uma visível transformação da relação entre o homem e o trabalho.Com a abundância da informação, as tecnologias digitais são a base para a construção de novos processos oportunizando a reestruturação global da economia, da educação e da sociedade como um todo. Observa-se um dos efeitos da tecnologia sobre a saúde, quando se considerando o estresse como uma situação que resulta da interação entre o indivíduo e o meio ambiente. No campo da educação, compreender como será possível para educação, diante do avanço tecnológico, cumprir seu papel de formação e as possíveis consequências. Diante do exposto, o GP ET&S apresenta esta proposta, com o objetivo de realizar uma revisão sistemática com ou sem metanálise para verificar as consequências do avanço tecnológico sobre a educação, trabalho e saúde.
On the computation of upper approximations to ultimate ruin probabilities in case of DFR claimsize distributions
Creators: name: Barzanti, L.

Publisher: name: Dep. of Statistical Sciences "Paolo Fortunati", Università di Bologna
Year: 2007

description: In the present note we consider the classical continuous time model of the collective theory of risk under the assumption that the claimsize distribution is DFR (decreasing failure rate) so that, according to well known queueing results, the ultimate ruin probability turns out to be convex. This property is exploited to develop a stable recursive formula for the calculation of a numerical upper approximation to the ultimate ruin probability with a remarkable improvement over analogous existing algorithms. Numerical results are reported to show the merits of the proposed approach.

description: This paper is contemplated to propose a class of shrunken estimators which is further used in constructing a class of preliminary test estimators for amount of information in complete samples from normal population when some ‘apriori’ or guessed value of amount of information is available and analyses their characteristics. The proposed classes of shrunken estimators and preliminary test estimators are compared with the usual unbiased estimator and MMSE estimator. Eventually, empirical study is carried out to demonstrate the performance of some shrunken estimators and preliminary test estimators of the proposed classes over the MMSE estimator. The suggested class of estimators is found to give gratifying results. Subsequently, the usage of proposed classes of estimators in estimating the precision of sample mean has been exclusively discussed followed by an example.

description: This study examines the asymptotic properties of a class of conditionally heteroscedastic location-scale time series models with innovations following a generalized asymmetric Student-t distribution (ASTD) or an asymmetric exponential power distribution (AEPD). We first show the consistency and asymptotic normality of the conditional maximum likelihood estimator of the model parameters under certain regularity conditions. Then, based on the maximum likelihood estimator, we estimate conditional value-at-risk (VaR) and expected shortfall (ES) by using their closed forms induced from the model. Their performance is finally compared with that of conditional autoregressive VaR and expectile methods. A simulation study and real data analysis are provided as an illustration.
Variance estimation using multiauxiliary information for random non-response in survey sampling

description: The goal of this paper is to study the properties of a class of estimators of population variance based on multi-auxiliary variables proposed by Srivastava and Jhajj (1980), under the two different situations of random non-response advocated by Tracy and Osahan (1994). The results are obtained under the assumption that the number of sampling units on which information could not be obtained due to random non-response, follows some distribution; for instance, see Singh and Joarder (1998), Singh, Joarder and Tracy (2000), Singh (2003).

Caught between the base and electoral reality

description: Malcolm Turnbull's position is terminal. He won't be prime minister by the next election. Last fortnight's much-reviewed excoriation of opposition leader Bill Shorten during question time all but sealed his demise. It wasn’t the content of that tirade that did it, rather the fact that he felt the need to put on such a show. That explosion was first and foremost a symptom of the prime minister's insecure standing among Liberal MPs. In the short term, it was a reaction to a Newspoll showing the government trailing Labor by eight points in voting intentions, the latest in a long line of bad polls.
Tony Abbott and Julia Gillard illustrated how a weak grip on the leadership can drive increasingly desperate behaviour designed to appeal to that tiny portion of Australians known as the party base. All it really does is further repel the bulk of voters and hasten the leader's demise.
A double-sampling approach for maximum likelihood estimation for a Poisson rate parameter with visibility-biased data

description: We propose a Poisson-based model that uses both infallible data and fallible data subject to misclassification in the form of false negatives that yield visibility bias. We than derive maximum likelihood estimators for the Poisson rate parameter of interest and the misclassification parameter under two different sampling scenarios. We also derive expressions for the information matrices and the asymptotic variances of the maximum likelihood estimators for the rate parameter and the maximum likelihood estimators for the false-negative parameter. Finally, we also study our new models via a simulation experiment and then apply our new estimation procedures to a real data set.

description: The use of longitudinal finite mixture models (FMMs) to identify latent classes of individuals following similar paths of temporal development is gaining traction in applied research. However, FMM’s users may be unaware of how data features as well as the inappropriate specification of the model’s covariance structure impacts class enumeration. To elucidate this, we investigated model fit-criteria curve behaviour across an array of data conditions and covariance structures. Fit statistic patterns were variable among the fit criteria and across a range of data conditions. This variability was greatly attributable to the level of class separation and the presence/absence of random effects. Our findings support some widely held notions (e.g. BIC outperforms other criteria) while debunking others (adding random effects is not always the solution). Based on the obtained results, we present guidelines on how the behaviour of fit criteria curves can be used as a diagnostic aid during class enumeration.

description: The movements of students between the faculties of the University of Bologna represent a complex evolving network. By mapping the electronic database containing all relevant data about the students, named “datawarehouse”, for three academic years (2004-2007), we aim to infer on the dynamics and the structural mechanisms that lead the evolution and topology of this complex system. Empirical measurements allow us to discover the topological characteristics of the network at a given moment, as well as their evolution in time. The results highlight stable ‘attraction’ and ‘escape’ nodes within the University network, and provide a simple description of the student movements and preferences.

The effects of correlation among observations on the consistency property of sample mean

Publisher: name: Dep. of Statistical Sciences "Paolo Fortunati", Università di Bologna
Year: 2013

description: E' noto che anche se le osservazioni campionarie sono correlate e non-normali la media campionaria converge in probabilità alla media della popolazione. Ma gli effetti della correlazione fra le osservazioni su questo tasso di convergenza sono incogniti, ed è proprio di questi effetti che tratta l'articolo. Si mostra che la media campionaria converge alla media della popolazione più velocemente se la correlazione è negativa, di quanto non faccia se le osservazioni sono indipendenti, e analogamente più lentamente se la correlazione è positiva. Così in presenza di correlazione negativa tra le osservazioni la consistenza della media campionaria è raggiunta con un numero di osservazioni uguale (o anche minore) di quello necessario nell'ipotesi di indipendenza. Ma se la correlazione è positiva la numerosità campionaria dipende dall'intensità della correlazione, e può essere estremamente grande per livelli elevati di correlazione positiva.
