description: Το ελληνικό κράτος κλήθηκε να καλύψει τις εκπαιδευτικές ανάγκες μεταναστευτικών ροών πριν τέσσερις δεκαετίες περίπου, τόσο των παλινοστούντων από την πρώην Ε.Σ.Σ.Δ. όσο και των ευάριθμων ροών από την Αλβανία. Κατά τις μεγάλες μετακινήσεις στα μέσα της προηγούμενης δεκαετίας, το φαινόμενο ξεπέρασε κάθε προηγούμενο στην περιοχή της Μεσογείου, σχετικά με τους πληθυσμούς που μετατοπίσθηκαν, τα προβλήματα που προέκυψαν, αλλά και τις συνεπακόλουθες ανάγκες στο εν λόγω πεδίο. Η παρούσα εργασία επιχειρεί μια σύνοψη στη διαχείριση της ενταξιακής διαδικασίας των ανήλικων προσφύγων, εστιάζοντας στον τομέα της εκπαίδευσης, ειδικώς στους Ασυνόδευτους και Διαχωρισμένους ανήλικους. Η ανάπτυξη υλοποιείται σε πέντε κεφάλαια, κατά τα οποία, αρχικώς γίνεται μια ευρύτερη αναφορά στο τυπικό της διαδικασίας υποδοχής/προστασίας/φροντίδας και συγκεκριμένα από την στιγμή της εισόδου του Ασυνόδευτου ανήλικου πρόσφυγα ή εντοπισμού του εντός της επικρατείας της χώρας και τις πρώτες διαδικασίες που ενεργοποιούνται. Στη συνέχεια ακολουθείται η διαδρομή μέχρι τη δομή και τις συνθήκες που θα φιλοξενηθεί, ενώ κατόπιν αναπτύσσεται περαιτέρω το στάδιο της ενταξιακής διαδικασίας στην εκπαίδευση, ως το πλέον ενδεδειγμένο όχημα για την επίτευξη της κοινωνικής του ένταξης. Στα πλαίσια του εκπαιδευτικού προγράμματος έμφαση δίνεται στη σημασία της Αισθητικής Αγωγής (Εικαστικών, Θεατρικής Αγωγής και Μουσικής), ως βέλτιστης μεθόδου εξωλεκτικής επικοινωνίας και εν προκειμένω όταν εκλείπει η δυνατότητα λεκτικής, λόγω γλωσσικής διαφορετικότητας. Τέλος σταχυολογούνται πέντε συνεντεύξεις, με ειδικότητες που γνωρίζουν εκ των έσω τις πραγματικές συνθήκες της διαβίωσης και της εκπαίδευσης των Ασυνόδευτων ανηλίκων προσφύγων.
Two-way data matrix representative syntheses of a three-way data matrix

Year: 2013

description: In questo lavoro sono studiate alcune matrici individui-variabili che sono delle sintesi rappresentative della matrice a tre indici individui-variabili-occasioni. Negli ultimi anni alcuni autori hanno definito matrici individui-variabili, che nella loro terminologia , costituiscono un compromesso,una sintesi, una media della matrice a tre indici . Sebbene queste matrici abbiano lo scopo comune di riassumere le caratteristiche della matrice a tre indici data, esse possiedono differenti proprietà ed apparentemente non hanno nulla in comune fra loro. Per questa ragione è interessante: 1) definire quali proprietà devono essere necessariamente possedute dalle sintesi rappresentative  delle matrici a tre indici; 2) individuare se esistono matrici con queste proprietà. E' naturale assumere che una matrice individui-variabili è una sintesi rappresentativa di una matrice a tre indici se: a) essa minimizza lo scostamento fra se stessa e la matrice a tre indici sull'insieme delle possibili matrici individui-variabili , secondo una prefissata distanza tra una matrice a tre indici e una a due indici; b) soddisfa la proprietà di internalità che può essere definita estendendo alle matrici la proprietà di internalità di una media individuata da Cauchy. Nella sezione 3 sono indicate alcune distanze tra una matrice a tre indici ed una a tre indici; nella sezione 4 sono individuate la matrice mediana  e la matrice media aritmetica che godono delle proprietà a) e b); nella sezione 5 si mostra che la matrice di Rizzi è una sintesi rappresentativa di quella mattrice a tre indici, che si ottiene dando alcuni pesi particolari alle variabili della matrice a tre indici originaria, mentre la matrice di Escoufier, sebbene sia stata definita compromesso, non possiede le proprietà a) e b) . Utilizzando una opportuna distanza tra le matrici a tre indici e quella a due indici si può definire una nuova sintesi, che possiede anche il vantaggio di riassumere meglio quelle matrici individui-variabili che spiegano la più ampia variabilità della matrice a tre indici. Nella sezione 6 , allo scopo di comparare differenti sintesi rappresentative della matrice a tre indici e di dare delle ragioni intuitive per la scelta di una matrice anzicchè di altre , vengono presentati alcuni esempi.

Some statistical problems related to singular spatial processes

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

description: In the literature upon the matter the problem of singularity is practically neglected.
The explanation that generally is given to this omission is that singular processes are too "pathological".
I think this is a rather partial point of view.
So in the paper I have tried to illustrate this position briefly examinating (sometime sending back to an appropriate bibliography) the ways choosen to solve the problem (even if the solution is still hard to find, as it is noted in the text). So I examine a way that should let some procedure of estimation.
In the first and second paragraphs are used existing definitions and theorems, in the third paragraph some useful properties of the L-fields are developed.
In fourth and fifth paragraph are exposed some procedures of estimations of tests.
In the last paragraph the conclusions and the open problems are enclosed.

Μία εταιρεία και ιδιαίτερα μία ναυτιλιακή εταιρεία μπορεί να θεωρηθεί ανταγωνιστική, όταν έχει σαφή αποστολή, σαφή δέσμευση ώστε να παρέχει ποιοτικές υπηρεσίες και όταν έχει επίσης τη δυνατότητα να προσαρμόζεται γρήγορα στις ανάγκες και τις ευκαιρίες του πελάτη παρέχοντας ανταγωνιστικές υπηρεσίες. Επιπλέον, μία ανταγωνιστική εταιρεία θα πρέπει να έχει την ικανότητα να δημιουργήσει ένα ανταγωνιστικό ανθρώπινο δυναμικό. Σε αυτή τη μελέτη, σκοπεύουμε να αξιολογήσουμε τις πρακτικές ανθρώπινου δυναμικού στις ναυτιλιακές εταιρείες και το θέμα της ισότητας των γυναικών στον κλάδο αυτόν. Οι παρατηρήσεις από την ναυτιλιακή εταιρεία (1) στην οποία δόθηκε το ερωτηματολόγιο αναλύθηκαν για να αναδειχθούν οι πρακτικές διαχείρισης ανθρώπινου δυναμικού που εφαρμόζονται καθώς και θέματα που άπτονται της προώθησης των γυναικών στη ναυτιλία. Τα αποτελέσματα που προέκυψαν συνεισφέρουν στην υπάρχουσα βιβλιογραφία καθώς είναι χρήσιμα για τους ναυτιλιακούς οργανισμούς προκειμένου να βελτιωθεί η ίση και αποτελεσματική πρόσβαση των γυναικών στη ναυτιλία.
Applicability of the Generalized Method of Moments to Tests of the Intertemporal capital Asset Pricing Models
Creators: name: Paruolo, P.
Publisher: name: Dep. of Statistical Sciences "Paolo Fortunati", Università di Bologna
Year: 2013

description: Since their first derivation, the continuous-time Intertemporal Capital Asset Pricing Models have encountered substantial problems in empirical tests. Hansen and Singleton (1982) have suggested to use the generalized method of moments to estimate and test the discrete-time expected utility maximization Euler equations. This method provides a test of a composite hypotesis of the model and of the specified type of preferences and strong-consistent, asim-protically normally distributed estimators.

Foreign patients' perceptions of healthcare services in a private hospital in Thailand: development of an integrative model
Creators: name: Prajitmutita, Manassanan
Publisher: name: Swinburne
Year: 2024

description: The hospital industry is a lucrative business, especially when it involves foreign patients as customers. Millions of foreigners receive medical treatment outside of their home country each year, and foreign patients have become a valuable market segment of the hospital industry, as they generate huge revenue for the industry worldwide. The competitive environment of the industry is not only local but has also expanded to include international clients. Hospital marketers are therefore, forced to adapt strategies to gain a significant advantage over competitors. Factors such as Service Quality (SQ), Customer Satisfaction (SAT) and Customer Value (CV) are identified as predictors of Behavioural Intentions (BI) that enhance competitive advantage in the services literature. A number of researchers have studied the perception of patients to SQ, CV, SAT and BI; however, research focusing on foreign patients’ perceptions is rare. ‘Foreign patients’ is chosen as a sample of the study because they are an important market segment of healthcare consumers and there is little research available on foreign patients’ perception of healthcare services.

description: The paper is concerned with the problem of discriminating two ancient populations with respect to the presence of the "Istituto delle Partecipanze", a sort of collective property of the land, beginning in 125 3 in some areas of the Emilia region. A time series analysis on the marriages registered in the last four centuries has been performed and different classes of the ARIMA models have been fitted to the data. The results give evidence to the heterogeneous development that characterizes the two populations in some aspects of the their bio-demographic history.

The framing of federal domestic violence policy responses

Publisher: name: Swinburne
Year: 2024

description: This paper analyzed the Australian Government’s response to the 2010 Report on Family
Violence produced the by Australian Law Reform Commission (ALRC) which, at the time,
represented one of the most significant documents framing the problem of domestic violence in Australia (Bacchi 2009). By focusing on two specific sites of purported ‘policy reform’ in response to the Commission report, Bacchi’s (2009) problemitisation framework revealed how the Government framed their action and inaction on the issue of domestic violence. An examination of how the social problem of domestic violence was residualised (Jamrozik & Nocella 1998) found that the Government framed their response to the recommendations as behavioural and technical concerns amenable to educational and administrative solutions.
Consequently the aim of the report to improve the safety of victims has not been achieved.

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

description: The possibility of obtaining subregional estimates of different crops on the basis of a regional sample currently employed in a survey on the characteristics of Italian farms is explored. Four linear models are rested, which employ the auxiliary information coming from the individual data of the Census of Agriculture at different extents. In general, a reduction of variability, expressed by the coefficient of variation, is obtained, but the strategy to adopt is not unique: there is to consider jointly the detail of modelization, i.e. the quantity of auxiliary information to employ, the size of the subareas together with the diffusion and incidence of the particular crop.

The formalization of the intuitive idea of statistical indexes
Creators: name: Gastaldi, T.
Publisher: name: Dep. of Statistical Sciences "Paolo Fortunati", Università di Bologna
Year: 2013

description: After a brief analysis of the concept of statistical index the author explains the general requirements which a statistical index has to satisfy. The main requirement is for the characteristics actually measured by the index to coincide with the characteristic to be quantified of which one usually has an intuitive idea. Formally this means that the total preordination which the index induces on the set D of the possible distributions must not contradict the preordination which can be defined in D on the sole basis of intuitive evidence. Another important requirement is for the value which the index takes in relation to any distribution not to be blatantly disproportionate with the intensity assumed by the characteristic under examination in that distribution. The author points out that disregarding this requirement means not to recognize interpretative meaning in the quantification produced by the index. To ignore it would be to consider the statistical index as a mere tool for comparing distributions in relation to the characteristic under examination. The opportunity of utilizing the increasing transformations of the indices that in practice have been shown to be right for quantifying a certain characteristic as indices of the same characteristic is also discussed. On the basis of this a "conservation principle for the descriptive capacity" of the index is attained. Through this the "advantages" and "disadvantages" acquired in any increasing transformation can find a global form of compensation. In conclusion it is observed that the quantification produced by the index limited though it may be due to certain instances of an intuitive nature distinguishes such an index from any other and gives it a certain peculiar "interpretation of reality". In the light of this indices may be considered as "bridges" throw down by our rational abilities between those points of solid ground where logic is backed up by the intuitive notion we have of the measured characteristic. They also represent real "artificial senses" capable of selecting only those aspects of reality through which we have rendered them perceptible this forming a "filtered" image by means of their functional structure. Each individual index contributes to the building up of an image of reality or rather of the distribution we are interested in studying in the same way that each of our ordinary senses contributes to the erection of an image of external reality.

On product estimation in simple random sampling
Creators: name: Herzel, A.
Publisher: name: Dep. of Statistical Sciences "Paolo Fortunati", Università di Bologna
Year: 2013

description: The variance and the mean square error of the biased product stimator, as well as the variance of the unbiased estimator, are computed in terms of population moments in sampling both with and without replacement. It is shown that the preferability of one or the other estimator depends on the population. Unbiased sub-optimal estimators of the variances and the mean square errors are computed in terms of sample moments. On the basis of these results, a data-adaptive estimator is proposed. Questions relative to transformations of the auxiliary variate and to multivariate product estimation are also discussed.

description: Conditional completeness is shown to provide a sufficient condition for maximal ancillarity. Using properties linking ancillarity and complete sufficient statistics, the new condition is shown to be more general than another sufficient condition given by Basu (1959). It is also of more practical interest and, under that condition, an apparent contradiction between the principle of sufficiency and the principle of conditioning is clarified.

The relevance of translating research findings into policy recommendations
Creators: name: Casal-Sanchez, Lola
Publisher: name: Zenodo
Year: 2022
Subjects: Policy; research, ageing

description: Current knowledge produced by science often fails to have real-life policy implications. To promote a real age-friendly society, which advocates for equality and helps older adults to realize their full potential, translations of research findings into policy are needed to develop and evaluate interventions to reduce ageism in different settings and spheres of life. This is where evidence-based research is most lacking, and as a result, policies to address ageism are either ineffective or absent. This presentation will approach key challenges and opportunities for translating research into impactful development programming and policy to close the gaps between knowledge, policy, and practice. A holistic policy approach is needed to support anti-discrimination legislation, broad awareness-raising and educational campaigns to build on a participatory approach and intergenerational social dialogue.
description: This presentation was part of an symposium that aimeed to vide an overview of the manifestations of ageism in international policy documents and frameworks in different fields such as technology, the media and the labor market. The presentations pursued to reveal the prevalence of ageism and the under-acknowledgement and lack of understanding of its complexity. During the symposium, presenters exposed concrete, evidence-based policy measures on the international, national, regional, and local levels to combat ageism and foster healthy and active ageing strategies employing an intersectional and diversity sensitive life-course perspective.
Forecasting with the input-output model: some econometric problems
Creators: name: Gardini, A.
Publisher: name: Dep. of Statistical Sciences "Paolo Fortunati", Università di Bologna
Year: 2013

description: The starting point of this paper is a review of the standard input-output forecasting methodology and of some of the developments in the stochastic context. This review shows the basic hypothesis and the limits of the traditional methodology. In  order to avoid these limits the problem is reformulated in the context of statistical inference, introducing the concept of estimate of the matrix of technical coefficients and deriving the variance-covariance matrix of the reduced form coefficients (Leontief-inverse) and of the prediction. In this context the traditional components of the prediction error appear as nothing else than neglected estimation problems.

The Photovoltaic Support Scheme in Germany
Creators: name: Gawel, Erik
Publisher: name: My University
Year: 2013

description: The German Renewable Energy Sources Act (Erneuerbare-Energien-Gesetz EEG) promotes the generation of electricity from renewable energy sources by a feedin tariff scheme. In general, renewables are considered to be environment-friendly with respect to climate change and other environmental harm associated with fossil-nuclear energy provision. In fact, renewables themselves cause new environmental costs regarding space requirements, related land-use con?icts and the need for scarce raw materials. Therefore, support policies should not only take into account economic but also ecological criteria. The objective of this study is to assess whether or not environmental criteria are re?ected in the German photovoltaic support scheme stipulated by the EEG. It thereby aims to establish a connection between the economic investment stimulus of renewable electricity support schemes and the environmental performance of their supported technologies taking photovoltaic as an example.

Approaching Workforce Diversity in Care Homes
Creators: name: Casal-Sanchez, Lola
Publisher: name: Zenodo
Year: 2022

description: Despite the ageing of the population having prompted an increment demand in care home services, and the degree of cultural diversity increasing in the workforce of care homes, little is known about the implication of workforce diversity in care homes and its impact on quality care, employee’s well-being, and organisational performance in care homes.
 This presentation addresses this knowledge deficit and with the aim of gaining an understanding of the influences and implications of the cultural complexity that care homes might face due to the increasing degree of diversity in the workforce and the ageing population. The presentation is based on the scoping literature review study conducted to explore the implications of workforce diversity on the well-functioning dynamics of the care team workforce as well as on the quality of care. The outcomes of the study aim to identify gaps that might contribute to eliminate any potential disadvantages for the older age groups as well as for migrant workers or workers from minority groups.
Il metodo del bootstrap nella propagazione degli errori

description: This note illustrates, through a very simple example, the power and flexibility of the bootstrap method to assess in a straightforward and unambiguous way how the random errors in direct measurements propagate themselves into the derived quantities of interest.
Furthermore, a version of the bootstrap with the initial data set generated by Monte Carlo has proved to be suitable in situations where the standard deviations of the directly measured quantities may be considered as known, but the effect of various experimental errors on the accuracy of final results is quite obscure.

Stima dei dati su fecondità ed abortività in piccole aree
Creators: name: Dalla Zuanna, G.
Publisher: name: Dep. of Statistical Sciences "Paolo Fortunati", Università di Bologna
Year: 2013

description: The possibilities to get reliable estimates of fertility and of spontaneous and induced abortion for small areas (italian municipalities) are discussed. After a swift description of the published official statistics, two methods are explained in detail.
The own-children method is good because of its completeness. In fact, you can get estimates of age specific fertility rates (until the 15th year before the survey) using only the census micro-data (or the micro-data extracted from the municipal population registers) and without using any other female population statistics, seldom available for small areas. The own-children method is applied to the set of the most populated five towns of the Veneto (Venezia, Verona, Padova, Vicenza and Treviso), either on the census data (1971 and 1981) or on the municipal data (1986). The differences in the results are discussed, comparing estimates of the same years resulting from two different surveys (1971 vs 1981 and 1981 vs 1986), and comparing the own-children estimates with the official statistics.
Finally, the hospitalization statistics are used together with the official statistics to build detailed data on fertility and induced abortion. A general method is discussed and tested using the hospitalization data concerning the Veneto. Good fertility estimates are obtained (age specific fertility rates), while the abortion data are less sure, especially for the municipalities of the eastern side of Treviso and Venezia provinces.

description: Consider N statistical units (U), p variables (X), and K occasions or sources of data (O). Cluster analysis for three way and three mode data matrices can concern itself with many aspects. We can group the K matrices in m homogeneous clusters following the scheme
{ O; (U; X) } . In the scheme { U; (X; O) } we seek m clusters of matrices (variables per occasion) of homogeneous units. In the scheme  { X; (U; O) } the matrices (units per occasion) are grouped in function of homogeneous variables. For two mode and three way matrices
the schemes are {O; (X; X)} and {O; (U; U) }.
In this paper, after recalling the INDCLUS and ADCLUS algorithms, two more recent proposals by Bellacicco-Ronzoni and Chiodi are illustrated. At the end a new algorithm, PRINCLUS, based on the individuation of m < K principal matrices is presented.

La connessione e la correlazione tra due matrici dei dati componenti una matrice a tre indici

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

description: In this work, starting from the statistical knowledge about connection and correlation between couples of variables, the author carries out a systematic study and a critical examination on these two relations among couples of data matrices belonging to a three-way data matrix.
Analogously to linear measures among variables, the measures of correlation between two matrices have to indicate the "direction" of dependence of the whole variables set of a data matrix with that of the other data matrix. In other words measures of correlation between couples of matrices have to evaluate whether all variables of a matrix are more frequently concordant or discordant with all variables of the other matrix.
After defining the mathematical notation for the three-way data matrix, two different ways to measure the correlation between couples of matrices are examined and also conditions necessary to define it are given.
The covariance and correlation between couples of matrices are matrices are introduces . These indices  have two main requirements they become well-known measures of correlation among couples of variables when matrices degenerate into vectors; they measure the correlation among couples of matrices as a function of the measures of correlation among couples of variables, these last in the couple each one belonging to a matrix.
The statistical meaning about connection between a couple of matrices can be explained according to the well-known meaning of this relation among variables. Two matrices are not connected with each other if any variable of one matrix is not connected with any variable of the other matrix.
Also the measures of connection between couples of data matrices have two main properties they become well-known measures of connection between couples of variables when matrices degenerate into vectors; they measure the connection between two matrices as a function of measures of connection between couples of variables, these last each one belonging to a matrix.

description: BACKGROUND: Animal African Trypanosomiasis (AAT) is one of the most economically important diseases affecting livestock productivity in sub-Saharan Africa. The disease is caused by a broad range of Trypanosoma spp., infecting both wild and domesticated animals through cyclical and mechanical transmission. This study aimed to characterize trypanosomes present in cattle at regular intervals over two years in an AAT endemic and a non-endemic region of Ghana. METHODOLOGY/PRINCIPAL FINDINGS: Groups of cattle at Accra and Adidome were selected based on their geographical location, tsetse fly density, prevalence of trypanosomiasis and the breed of cattle available. Blood for DNA extraction was collected at approximately four to five-week intervals over a two-year period. Trypanosome DNA were detected by a sensitive nested PCR targeting the tubulin gene array and massively parallel sequencing of barcoded amplicons. Analysis of the data was a semi-quantitative estimation of infection levels using read counts obtained from the sequencing as a proxy for infection levels. Majority of the cattle were infected with multiple species most of the time [190/259 (73%) at Adidome and 191/324 (59%) at Accra], with T. vivax being the most abundant. The level of infection and in particular T. vivax, was higher in Adidome, the location with a high density of tsetse flies. The infection level varied over the time course, the timings of this variation were not consistent and in Adidome it appeared to be independent of prophylactic treatment for trypanosome infection. Effect of gender or breed on infection levels was insignificant. CONCLUSIONS/SIGNIFICANCE: Most cattle were infected with low levels of several trypanosome species at both study sites, with T. vivax being the most abundant. The measurements of infection over time provided insight to the importance of the approach in identifying cattle that could suppress trypanosome infection over an extended time and may serve as reservoir.

Protecting Commodity Operating System Kernels from Vulnerable Device Drivers

description: Device drivers on commodity operating systems execute with kernel privilege and have unfettered access to kernel data structures. Several recent attacks demonstrate that such poor isolation exposes kernel data to exploits against vulnerable device drivers, for example through buffer overruns in packet processing code. Prior architectures to isolate kernel data from driver code either sacrifice performance, execute too much driver code with kernel privilege, or are incompatible with commodity operating systems. In this paper, we present the design, implementation and evaluation of a novel security architecture that better isolates kernel data from device drivers without sacrificing performance or compatibility. In this architecture, a device driver is partitioned into a small, trusted kernel-mode component and an untrusted user-mode component. The kernel-mode component contains privileged and performance-critical code. It communicates via RPC with the user-mode component which contains the rest of the driver code. A RPC monitor mediates all control and data transfers between the kernel- and user-mode components. In particular, it verifies that all data transfers from the untrusted user-mode component to the kernel-mode component preserve kernel data structure integrity. We also present a runtime technique to automatically infer such integrity specifications. Our experiments with a Linux implementation of this architecture show that it can prevent compromised device drivers from affecting the integrity of kernel data and do so without impacting common-case performance.
Ker-I Ko and the study of resource-bounded Kolmogorov complexity

Minimum circuit size problem

description: Ker-I Ko was among the first people to recognize the importance of resource-bounded Kolmogorov complexity as a tool for better understanding the structure of complexity classes. In this brief informal reminiscence, I review the milieu of the early 1980’s that caused an up-welling of interest in resource-bounded Kolmogorov complexity, and then I discuss some more recent work that sheds additional light on the questions related to Kolmogorov complexity that Ko grappled with in the 1980’s and 1990’s. In particular, I include a detailed discussion of Ko’s work on the question of whether it is NP-hard to determine the time-bounded Kolmogorov complexity of a given string. This problem is closely connected with the Minimum Circuit Size Problem (MCSP), which is central to several contemporary investigations in computational complexity theory.
Fast and Accurate Semi-Supervised Protein Homology Detection with Large Uncurated Sequence Databases

description: Establishing structural and functional relationship between sequences in the presence of only the primary sequence information is a key task in biological sequence analysis. This ability is critical for tasks such as inferring the superfamily membership of unannotated proteins (remote homology detection) when no secondary or tertiary structure is available. Recent methods such as profile kernels and mismatch neighborhood kernels have shown promising results by leveraging unlabeled data and explicit modeling mutations using mutational neighborhood. However, the size of such neighborhood exhibit exponential dependency on the cardinality of the alphabet set which incurs expensive cost for kernel evaluation and hence hinders the use of such powerful tools. Moreover, another missing component in previous studies for large-scale semi-supervised protein homology detection is a systematic and biologically motivated approach for leveraging the unlabeled data set. In this study, we propose a systematic and biologically motivated approach for extracting relevant information from unlabeled sequence databases. We also propose a method to remove the bias caused by overly represented sequences which are commonly seen in the unlabeled sequence databases. Combining these approaches with a class of kernels (sparse spatial sampling kernels, SSSK) that effectively model mutation, insertion, and deletion, we achieve fast and accurate semisupervised protein homology detection on three large unlabeled databases. The resulting classifiers based on our proposed methods significantly outperform previously published state-of-the-art methods in performance accuracy and exhibit order-of-magnitude differences in experimental running time.

description: We present improved uniform TC 0 circuits for division, matrix powering, and related problems, where the improvement is in terms of “majority depth” (as studied by Maciel and Therien). As a corollary, we obtain improved bounds on the complexity of certain problems involving arithmetic circuits, which are known to lie in the counting hierarchy.

description: The use of empirical indicators and composite indices for the measurement of multidimensional phenomena (i.e. quality of life, health, social welfare, etc.) implies a series of conceptual and methodological problems here analysed in view to construct composite indices statistically significant i.e. valid and reliable.
In applied research in different domains one needs only one measure, an index of a multidimensional phenomenon to compare it with others and put it in complex statistical models. After a statistical definition of index (composite indicator) the A. describes with examples
and discusses in detail four different methods of constructing composite indices.
At the end advantages and disadvantages of the four methods are briefly examined.
