Sull'analisi di serie spaziali non stazionarie. un metodo basato sul ricampionamento
Creators: name: Arbia, Giuseppe
Publisher: name: Dep. of Statistical Sciences "Paolo Fortunati", Università di Bologna
Year: 2013

description: In this paper we consider the problem of estimating the unknown parameters  of non-stationary spatial process when only a single replication of the process is available. The approach suggested here, to overcome the problem of estimating a number of parameters a lot larger then the number of observation, is based upon the general idea of resampling. A set of "moving subsample" are considered in the study area and the unknown parameters are estimated within them. An application of the method to some agricultural field trials data is also considered in the paper.

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

description: The work considers the problem of detecting a change (soft-failure) in the dynamic structure or in the input structure of a real input/output system. The system diagnostic is based on the ARMA representation of the real system, where only output data are available. Under the no-rupture hypothesis the statistical properties of the residuals or the so called innovation process are well known. In the present paper, through the definition of a general rupture model, the asymptotic properties of the residuals under rupture hypothesis are studied. Certain residual-based rupture tests are introduced, one of them is exact sized while the others are shown to be asymptotically normal. Their asymptotic behaviour under both hypotheses is studied by means of the introduced rupture model.

description: The seasonal behaviour of bank deposits is to a large extent influenced by interest payments. In Italy this problem is particularly serious because, in the past, interests on bank deposits were paled only once a year (in December). The seasonally of bank deposits thus changes over time and it is highly correlated with the level of interest rates. This paper shows that the standard XllARIMA procedure is unable to remove seasonally from the series of Italian bank deposits and suggests several suitable alternatives.

Mesures environnementales

description: La simulation du comportement thermique des panneaux photovoltaïques a fait l'objet de nombreuses publications ces dernières années, allant des solutions empiriques simples aux modèles numériques tridimensionnels complexes. Pour valider un modèle précis permettant d'évaluer la température des panneaux photovoltaïques en fonction des conditions environnementales, un dispositif de mesure a été mis en place. Il enregistre des données cruciales telles que la vitesse du vent, la température et l'humidité de l'air, les températures du sol, et la température radiative de la voûte céleste, la température de la face arrière des modules PV et les flux radiatifs (solaires directs et diffus -issu de la voûte céleste et réfléchi par le sol- , infrarouges intermédiaire ascendant et descendant). Cette campagne de mesure s'étale sur une année complète, avec une fréquence d'acquisition de l'ordre du Hertz et des moyennes prises par minute. La confrontation entre ces mesures et un modèle analytique simple prenant en compte le gradient thermique dans l'épaisseur du panneau montre que ce dernier permet d'obtenir la température des cellules avec une incertitude inférieure au degré Celsius lorsque les différents flux thermiques qui interviennent dans les échanges entre le panneau photovoltaïques et son environnement immédiat sont correctement pris en compte. Cette comparaison fait apparaître la pertinence du modèle pour l'intégralité de la campagne de mesure. Une comparaison avec les modèles empiriques utilisés en général pour prévoir la production des installations où la température n'est pas mesurée, montre l'apport de ce modèle simple. En conclusion, ce modèle numérique validé se révèle être un outil efficace et rapide pour analyser les différents facteurs qui influent sur l'efficacité des panneaux photovoltaïques. Il permet notamment de quantifier l'importance relative des différents flux thermiques et de prédire le comportement des panneaux en fonction de leurs constituants. Cette avancée est cruciale pour l'optimisation et l'amélioration des panneaux photovoltaïques, contribuant ainsi à une utilisation plus efficace de l'énergie solaire.

description: Approach behavior, defined as differences in behavior to an incentive event and anger at its removal, was assessed during contingency learning in 87 5-month-olds was related to maternal ratings of mastery behaviors at two years. Mothers reported on infants’ concurrent temperament, as well as the occurrence of anger and tantrums, and their own anger at 12 months. Approach behavior was expected to predict persistence with objects and persistent motor behavior, but not negative reactions to failure. Negative reactions to failure were expected to be mediated by a distress-prone temperament. The moderating effect of maternal anger on these relations was also explored using conditional process regression models. Controlling for soothability, early approach behavior predicted toddlers’ persistence, especially gross motor persistence, moderated by maternal anger. With more maternal anger, approach behavior and toddler’s persistence were more strongly related. Distress to limits, infant anger at 12 months, and maternal anger were significantly correlated, but only infant anger was related to negative reactions to failure. Prior to six months, goal-directed behavior is related to later behavioral persistence, but maternal responses to child anger are an important contributor to this relation and by 12 months, infant anger directly predicts mastery frustration at two years.

description: This presentation was part of the webinar What is Ageism? Ageism in the Social Media at University of Third Age, Scotland, 26 April 2021. In this webinar, members of the European Network EuroAgeism provided insights into current research on ageism in the media. The media (e.g. newspapers or social media sites) can be seen as one of the many institutions that contribute to the construction of stereotypical images of ageing and old age. At the same time, the media can play a crucial role in breaking stereotypes and helping to solidify the socially and culturally constructions about older people and late-life. Among other research, an example of ageist portrayal of nursing homes in newspapers during COVID-19 were discussed. During the first part of the webinar activities of the whole EUROAGEISM H2020 project in all 15 FIPs/ESRs projects were introduced
Optimal Battery Sizing for Storm-Resilient Photovoltaic Power Island Systems

Subjects: Solar array resiliency

description: Photovoltaic systems with battery storage are analyzed from the perspective that they can operate as a local power island in circumstances of storm-damage or other grid outage. The specific focus is to determine the optimal battery size for a given solar array size, taking into account reasonable day-to-day and seasonal sunlight variations as well as efficiency losses when converting from DC to AC for connection to the grid, or for provision of power during island mode. Three locations in the United States are used as case studies (Newark NJ, Boulder CO, and Tucson AZ). These provide a wide range of sunlight characteristics and illustrate variability factors that will be similar to many locations in continental North America. The analysis of the probability distributions for sunlight brightness then allow for the establishment of a 95% confidence rating for the steady-state power output from a specific combined battery and solar array configuration when faced with a grid interruption. This rating system can be used as a guide for designing systems for future installation.

Year: 2024

description: Adsorption of diastase over natural halloysite nanotubes is studied in order to evaluate the adsorption capacity of diastase. The halloysite surface characteristics were assessed using nitrogen adsorption, x-ray diffraction (XRD), thermal gravimetric analysis (TGA) and Fourier transformed infrared (FTIR). The surface area of the natural halloysite is found to be 51 m 2 •g -1 , with total pore volume of 0.106 cm 3 •g -1 . The natural halloysite has a basal spacing (d001) of 10 Å confirming the structure of the natural halloysite material. TGA results indicated that halloysite loses its interlayer water in the range of 30 to 105 °C and the dehydration in the structural layer above 150 °C. The dehydroxylation of halloysite has occurred at approximately 460 °C. The FTIR result of the thermally treated halloysite sample indicated that the bands observed are assigned to Si-O and Al-O bonds. The effects of solution pH and temperature were studied on the adsorption capacity and percent removal of diastase from the solution. The adsorption kinetic found to fit well with both the Pseudo first-order and Pseudo second-order models, and the values of the kinetic constant were found to be 0.173 min -1 and 0.00018 g•mg -1 •min -1 respectively. The Langmuir isotherm model is found to fit well to the adsorption data and a kinetic value is found to be 0.00059 m 3 •g -1 . The maximum adsorption capacity was found to be 370 mg•g -1 , indicating the potential for applications of the natural nanostructured halloysite material as an effective adsorbent for diastase.

description: Cystinuria, a rare genetic disorder, is characterized by defective L-cystine reabsorption from the renal proximal tubule, resulting in abnormally high concentrations of l-cystine and subsequent L-cystine crystallization in urine and stone formation in the urinary tract. Inhibition of L-cystine crystallization by L-cystine diamides such as LH708 (2) represents a promising new approach to prevent stone formation in patients with cystinuria. While 2 shows promising in vivo efficacy and a good safety profile in a Slc3a1-knockout mouse model of cystinuria, further structural modification of 2 led to the discovery of 8-L-cystinyl bis(1,8-diazaspiro[4.5]decane) (LH1753, 3) incorporating a bioisosteric spiro bicyclic diamine 1,8-diazaspiro[4.5]decane for the N-methylpiperazine terminal groups in 2 as a promising candidate with 3 being about 120x more potent than l-cystine dimethyl ester (CDME, 1) and about 2x more potent than 2 in inhibiting l-cystine crystallization. Furthermore, 3 demonstrated good oral bioavailability and in vivo efficacy in preventing l-cystine stone formation in the Slc3a1-knockout mouse model of cystinuria.
Fixed point languages of deterministic generalized sequential machines are context sensitive
Creators: name: Walker, Adrian
name: Van der Mude, A.
Publisher: name: Rutgers University
Year: 1978

description: Fixed points of operators are widely studied, and they have been used to describe, for example, the semantics of recursive function definitions (Manna & Shamir [1977]), stability in discrete models for biological development (Herman and Walker [1976]), and to obtain results about cellular spaces (Takahashi [1976]). The regular languages have been characterized by Van Leewen [1975] as homomorphic images of the fixed points of monogenic functions. Herman and Walker [1976] have shown that the set of fixed points of an L-scheme, that is the set of all strings over an alphabet such that each string derives only itself under parallel replacement rules, is a regular language. This result was obtained by showing that, in a self-derivation step, a descendant sub string could only be located a bounded distance to the left or right of its parent sub string. Since the parallel replacement rules of an L-scheme can easily be encoded as a deterministic generalized sequential machine (DGSM) transduction, see e.g. Ginsburg [1966] for a description of a DGSM, - the question arises whether the fixed-point language of a DSGM is also a regular language. A related question is whether, during a DGSM transduction of a string into itself, the amount by which the output lags or leads the input is bounded by a constant. In this paper we show that such a constant bound does not exist, and that the device of defining a language as the set of fixed points of a DGSM has surprising power, namely, some of the languages so generated are not context-free. Since we show that the fixed point languages of DGSMs are accepted by deterministic LBAs, and since it has been pointed out by Ginsburg [1966] that the complement of the fixed point language of a DGSM is a context-free language, our results may suggest some new ways of studying the well known LBA problem, - whether or not there exists a language accepted by an LBA but not by any deterministic LBA.

description: The current experiment addresses the proposal by Cheng & Rooryk (2000) that wh-in-situ questions in French are marked by an obligatory rising contour, which is the result of an intonation morpheme [Q: ] in C. Twelve native French speakers participated in a production study in which they produced the target interrogatives, along with a range of similar sentences. While most participants were perceived to assign wh-in-situ questions a sentence-final rise, a minority was not. Moreover, the rise associated with wh-in-situ was smaller than the rise exhibited in yes-no questions, which C&R claim to be licensed by the same morpheme. Given that these two results are unexpected under C&R’s account, we conducted a further acoustic analysis of the productions, which revealed that for sentences lacking a sentence-final rise, the the in situ wh-word had an elevated high pitch accent. A statistical analysis shows a negative correlation between the height of the pitch accent assigned to the wh-word and the presence and height of the sentence-final rise, indicating that instead of the sentence-final rise for wh-in-situ questions being optional, it may instead be variable and predictable by focus placed on the wh-word, for discourse reasons. We discuss three possibilities for the status of the intonation morpheme concerning yes-no and wh-questions and the role of information structure in French wh-in-situ questions.

description: Sexual harassment is a serious problem that continues to affect primarily women in the United States workforce today. The modeling industry within cultural economy—which focuses on the production of goods and services chiefly for their aesthetic value—presents significant challenges in this area as predominantly young girls are working in a field dominated by powerful men. Female fashion models must engage in networking entrepreneurial labor in what I call “the party life” in order to obtain employment, keep their jobs, and secure future work. This study uses qualitative content analysis to map out how the party life leads to incidents of sexual harassment with both personal and professional consequences for fashion models using 20 distinct narratives. Implications for how the party life actually occurs in the modeling field on a daily basis and how entrepreneurial labor and gendered power relations interact to produce sexual harassment are discussed. Finally, recommendations for reform in the industry are detailed.

description: Introduction: Universal provision of effective antiretroviral medication has been essential to reduce mortality, increase longevity, and reduce onward transmission of HIV. This study aims to illuminate persistent threats to the health and longevity of under-served PLWH in British Columbia (BC), Canada. Methods: Between 2007 and 2010, 1000 PLWH across BC were enrolled in the Longitudinal Investigation into Supportive and Ancillary health services (LISA) study and completed a cross-sectional survey on their HIV-care experiences and healthcare engagement. The sample generally reflects an under-served population of PLWH. A linkage to the provincial Vital Statistics registry is used in this analysis in order to examine overall mortality and cause-specific mortality trends; probability of death was modeled using logistic regression for participants with ongoing clinical monitoring (n = 910). Results: By June 2017, 208 (20.8%) participants had died. The majority of deaths 57 (27.4%) were attributed to drug-related complications or overdoses, 39 (18.8%) were attributed to HIV-related complications, and 36 (17.3%) to non-AIDS-defining malignancies. We observed elevated odds of death among PLWH who smoked tobacco (aOR: 2.11, 95% CI: 1.38, 3.23), were older (aOR: 1.06 per one-year increase, 95% CI: 1.04, 1.08), indicated heavy alcohol consumption (aOR: 1.57, 95% CI: 1.11, 2.22), and reported unstable housing (aOR: 1.96, 95% CI: 1.37, 2.80); while higher CD4 cell count was protective (aOR: 0.87 per 100-unit increase, 95% CI: 0.79, 0.94) as was male gender), though non-significant (aOR: 0.73, 95% CI: 0.49, 1.07). Conclusions: Overdose is - the leading cause of mortality among a cohort of under-served PLWH in BC, Canada. Public health efforts to end the HIV epidemic and support the health and well-being of PLWH are being thwarted by persistent health inequities and the enormous and persistent risks facing people who use drugs. Integrated low-barrier primary care is essential for supporting under-served PLWH, and safe drug supply is needed to support PLWH who use drugs.

His work has not to be seen only as instrumental to government activities but rather as guide to knowledge and decisions of every member of the social body: he offers a service in the form of a public good. In performing his duties, he must comply with usual norms of correctness, impartiality, respect of privacy and confidentiality, and so on, but he has also to go beyond to larger horizons. He should certainly care for professional competence in his field, but also be opened to dialogue with other experts, administrators and politicians. He should be able to understand and foresee problems, tensions,difficulties as well as material and spiritual resources of the society in which he lives  so to be capable to imagine, plan and create a relevant documentation needed for a better choice of the right way for solutions.

The fundamental theorem of prevision

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

description: We study de Finetti's "fundamental theorem of probability", reformulated in the finite case as a computable linear programming problem. The theorem is substantially extended, and shown to have important implications for the subjective theory of statistical inference. It supports an operational meaning for the partial assertion of prevision via asserted bounds. We extend the theorem to apply to quantities more general than events, to allow bounds and orderings on previsions as the input to the programming problem, and even to allow bounds on conditional previsions as the input and output. In a philosophical discussion, prevision is explicitly recognized as a completion of the notion of logical assertion, introduced by Frege. Partial prevision assertions then allow the representation of weaker forms of uncertain knowledge, spanning a range of possible numerical values for a quantity between the assertion of a precise prevision value and the mere unassertive contemplation of the quantity.

description: Les moteurs électriques à grande vitesse présentent une densité de puissance massique très élevée, avec des contraintes thermiques sévères. De plus, les conditions d'alimentation du moteur électrique par le convertisseur de puissance ainsi que sa commande influent considérablement sur les pertes Joule dans le bobinage, les pertes fer et les pertes dans les aimants permanents. L'analyse du comportement thermique d'un moteur, permettant l'évaluation des températures maximales atteintes par les matériaux, s'avère cruciale pour garantir ses performances et sa fiabilité. Le comportement thermique du moteur électrique peut être évalué à l'aide de méthodes numériques de type CFD (Computational Fluid Dynamics). Ces modèles, bien que puissants, présentent une complexité dans leur implémentation, nécessitent des ressources de calcul importantes, et sont généralement restreints aux phases de développement préliminaires. Cette étude présente le développement d'un circuit équivalent thermique en 2D et son application à une encoche statorique de moteur électrique. Le modèle permet de créer une géométrie en décomposant cette dernière en plusieurs régions. Les matériaux qui les composent sont considérés comme anisotropes et indépendants de la température, tandis que les sources de chaleur sont constantes et uniformes. Les transferts radiatifs sont négligés. Les conditions limites imposées aux frontières de l'ensemble peuvent être de différents types, telles qu'une température imposée, une convection avec un coefficient d'échange h et une température ambiante, ou une densité de flux. L'apport de ce modèle réside dans l'intégration des résistances de contact thermiques bidimensionnelles (r, $ heta$) qui peuvent être utilisées pour simuler un élément de faible épaisseur, permettant ainsi de réduire le maillage et donc le temps de calculs. Ces résistances peuvent également être utilisées pour introduire des lames d'air sur des surfaces de contact entre différentes régions, afin de se rapprocher de conditions expérimentales remettant en question l'hypothèse du contact parfait. L'un des cas présentés dans l'article concernera la simulation d'une fine couche isolante autour de la bobine par le biais de l'analogie des résistances de contact. Les résultats obtenus seront comparés à ceux issus d'une modélisation CFD en 3D simulant réellement cette couche isolante.

Projekti koski korkeakouluopiskelijoiden ajankäyttöä ja kuormittuneisuutta opinnoissa, sekä opetushenkilöstön näkemyksiä opintojen mitoittamisesta opintojaksoillaan.Tätä kyselyä käytettiin opetushenkilöstön opintojen mitoituskäytäntöjen ja kokemusten kartoittamiseen esimerkiksi koskien kurssitehtävien sopivaa määrää, sisältöä, sekä opintojaksoille varattua opiskeluaikaa. Taustamuuttujina käytettiin opettajien affiliaatiota, opetustehtävien määrää, opetusalaa, koulutustaustaaa, pedagogista koulutustaustaa, sekä akateemista opetuskokemusta vuosina.Kysely on uudelleenkäytettävissä myöhempiin tutkimuksiin. Viittaamista alkuperäiseen työhön odotetaan.
Mitigating transmission control protocol Incast congestion collapse with adaptive resolution round trip time measurement
Creators: name: Stewart, Lawrence A.
Publisher: name: Swinburne

description: Data-driven services delivered while the consumer waits are intrinsically sensitive to service delays impacting consumer experience. This can transfer to the financial bottom line when commercial interests are involved, such as with Internet web search and e-commerce. This thesis grows the body of knowledge regarding Incast congestion, a source of significant variable delay in delivering such services that rely on distributed computation. By developing free tools and using them to analyse the Incast phenomenon, a novel mitigation algorithm was developed which can improve service delivery times for Incast affected transactions, sometimes by more than an order of magnitude.
Estimation of Frechet disribution parameters by joint distribution of ' m ' extremes

description: By using three medians a quick method of estimation of the parameters of the Fréchet distribution was given by Gumbel (1965). Tiago de Oliveira (1972) estimated the parameters of the distribution using the maximum likelihood method. Recently Singh (1987) proposed the maximum likelihood estimates based on m extremes of several samples. However, the joint information of the lower extremes should be used because the information is necessary to be recorded to achieve the first extremes. In this paper the maximum likelihood estimates using the joint asymptotic distribution function of m extremes of several samples are derived. The variances and covariances of the estimates for every additional lower order extreme (up to the 20-th lower extreme) and for different values of the shape parameter are computed in order to examine the increase in the efficiency of the estimates due to the additional information of the lower order extremes.

La classe delle densità normali sghembe: aspetti inferenziali da un punto di vista Bayesiano
Creators: name: Liseo, B.
Publisher: name: Dep. of Statistical Sciences "Paolo Fortunati", Università di Bologna
Year: 2013

description: The Skew-Normal (SN) class of densities was introduced by A. Azzalini in 1985. His aim was to determine a statistical model, including normal densities, for handling a precise kind of departure from normality the skewness. In this paper we show the "strange" behaviour of the SN class from the point of view of likelihood based inference. Finally we compare the usual frequentist approach with a Bayesian analysis proving that the former corresponds to a "strange" prior distribution of the parameters of the SN densities.

Problemi relativi alla definizione e alla stima di una funzione del consuno regionale

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

description: A consumption function at the regional level is proposed and estimated on the basis of data of Sicily in the period 1951-85. The proposed function contains as specific variables both the regional income and the current transfers. An error correction model was used to account for short and long run effects as well as to get estimates in agreeement with the theory. The results are quite encouraging and allow us to draw some interesting conclusions, with respect to the role of current transfers in sustaining both the regional income and the aggregate consumption in the Sicilian economy.

Comparison of some Bayesian heteroscedastic error models

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

description: Heteroscedastic error models, with variance of the error term as proportional to the square of its expectation, have been considered. The distribution of the error term is assumed to follow either Normal, Lognormal or Gamma distribution. We estimate and compare these three different heteroscedastic error models from a Bayesian point of view using non-informative priors. A practical example which utilises expenditure data favours the Lognormal distribution to Gamma and Normal distributions.

Multi-omic analysis reveals phenotypic plasticity in colorectal cancer

description: Plasticity is a cell's ability to rapidly and reversibly alter its phenotype, typically without significant epigenetic remodeling. While plasticity is known to play an important role in many human systems, such as colon crypt maintenance, it may also help to explain how a single progenitor cell can give rise to a tumor with many different cellular phenotypes. We found evidence of phenotypic plasticity by examining DNA methylation profiles and single-cell RNA-Seq data from both normal colon crypts and colorectal cancers. Specifically, we found that genes with higher expression variability tended to have more conserved, or less variable, methylation profiles. However, many existing quantitative methods for the analysis of multi-omic data are designed to identify correlation or covariance between epigenetic features and gene expression. Such methods may not be well-calibrated to detect phenotypic plasticity, in which conservation, not variability, of the epigenome plays an important role.
Le rappresentazioni grafiche nel quadro della evoluzione della statistica in Italia nel XIX secolo

Year: 2013

description: The graphical representations in the context of the evolution of Statistics in Italy throughout the 19-th century are described. The article offers an excursus on the production of statistical graphs in Italy throughout the 19-th century. It is divided into two main parts. The first one refers to the situation prior to the reunification of the country, and the emphasis is placed upon authors such as Gioia, Romagnosi, Cattaneo, Messedaglia, Baldi (the author of one of the first examples of statistical charts together with Guerry), Giulio, Correnti and Maestro In the second part, the main graphic production of the period from the Unification of Italy up to the end of the century is covered; this period sees the "Direzione Generale della Statistica", under Luigi Bodio, as the main reference point of this production. Besides Bodio, the figure of Quintino Sella, Finance Minister of the period, must be recalled. He gave a contribution that was by no means negligible to the utilization of statistical graphs in Italy.

description: The worldwide initiative for citizen participation ̮World Wide ViewsŁ, which was first cooperatively led by Denmark and France in 2009, was the first opportunity to give the non-organized civil society a platform and a voice. In the year 2015, the citizen participation was organised on climate and energy questions in regards to the international climate conferences. In Germany, the civil dialogue included more than 70 randomly selected persons and took place on the 6th of July 2015. At the beginning, the citizens were informed about the present situation of the international climate conferences. After that, the citizens had the opportunity to discuss the questions pertinent to climate change negotiations in small groups. At the very same day of the consultation process the results of the German and the other participating countries were disclosed. Thus, opinions from almost 10,000 representatives of the civil society from 76 countries were captured. With the objective to feed in the results in the international negotiation process, inter alia, the German results, were presented into different fora international climate politics, for example the climate change conference in Paris in order to make them available to the climate change diplomats from all over the world.

description: Any statistical observational unit is probabilistic. The probability of such a unit has to be computed on the basis of homogeneous data if we do not want to violate the basic principle of the calculus of probability. The model of the homogeneous representativeness can be employed to test data for homogeneity.
