description: The heparan sulfate proteoglycan Syndecan-1, a mediator of signals between the extracellular matrix and cells involved is able to interact with OPG, one of the major regulators of osteoclastogenesis. The potential of osteoblasts to induce osteoclastogenesis is characterized by a switch of OPG (low osteoclastogenic potential) towards RANKL production (high osteoclastogenic potential). In the present study, we investigated the influence of endogenous Syndecan-1 on local bone-cell-communication via the RANKL/OPG-axis in murine osteoblasts and osteoclasts in wild type and Syndecan-1 lacking cells. Syndecan-1 expression and secretion was increased in osteoblasts with high osteoclastogenic potential. Syndecan-1 deficiency led to increased OPG release by osteoblasts that decreased the availability of RANKL. In co-cultures of Syndecan-1 deficient osteoblasts with osteoclast these increased OPG in supernatant caused decreased development of osteoclasts. Syndecan-1 and RANKL level were increased in serum of aged WT mice, whereas Syndecan-1 deficient mice showed high serum OPG concentration. However, bone structure of Syndecan-1 deficient mice was not different compared to wild type. In conclusion, Syndecan-1 could be regarded as a new modulator of bone-cell-communication via RANKL/OPG axis. This might be of high impact during bone regeneration or bone diseases like cancer where Syndecan-1 expression is known to be even more prevalent.

Prediction-based Monitoring in Sensor Networks: Taking Lessons from MPEG
Creators: name: Goel, Samir

Publisher: name: Rutgers University
Year: 2001

description: In this paper we discuss the problem of monitoring data sensed in large sensor networks. A sensor typically runs on a battery having a limited lifetime. In order to increase the lifetime of a sensor it is important that the mechanisms used in monitoring them be energy efficient. In this paper, we propose a new paradigm called Prediction-based monitoring for energy-efficient monitoring. We show that the paradigm can be visualized as a watching of a “sensor movie” and that concepts from MPEG may be applied to it. We have implemented the proposed algorithms in a testbed of Rene motes[Motes]. Experimental results show that the proposed solutions cut down the energy consumption by more than 5 times, considerably increasing sensor lifetimes, and thereby, the lifetime of the networks formed from these sensors.

description: Participation of civil society actors in the OMC process in one of dominant strands in current debate on the OMC. In this paper we aim to understand how social CSOs participate in the OMC inclusion; how participation changes the original role of CSOs in European policy making; and what kind of inter-organisational relations emerge between national and European CSOs. At the European level we study four European networks: EAPN, FEANTSA, Eurochild, and EDF. At the national level we analyse Lithuanian members of these European networks: EAPN Liyhuania, Caritas Lithuania, HRMI, and LNF. Our analysis is based on data that we obtained from interviews. In the case of European networks we also use documentary analysis on the basis of the networks’ publication on the OMC. Our findings suggest that participation of European networks in the OMC processes is not homogeneous. The latter finding is an important factor in studying relation between European networks and national CSOs, and gives a background to question the validity of the hypothesis, which is present in the literature, that national CSOs’ relations with European networks increase their mobilization around NAPs/NSR. In addition to that our findings shed light on difficulties that European networks face while participating in the OMC process, which apart from S. Kröger’s attempts, were generally ignored in the literature. At the national level we do not find any procedural shifts regarding CSOs implications of participation in NAP/NSR process. Our study confirms that European networks’ consultation and information providing role remains prevailing over collaboration and empowerment also in the OMC context. Meanwhile in the case of Lithuanian CSOs, there are signs that national OMC processes have created conditions for shaping more positive attitude on a governmental side, however they have not changed CSOs role essentially. Finally we find out that Lithuanian CSOs connection with European networks, as an important factor for mobilizing them around NAPs, was only partially true for Lithuanian case. In general terms the OMC’s contribution to Europeanise Lithuanian CSOs is limited. Our finding suggest that validty of statements regarding CSOs participation in the OMC in the ‘old’ member have limited applicability for the new member states such as Lithuania, and thus indicates a need for a new research strand on European governance-civil society relations in Central and Eastern Europe.

description: Normalization of various phase functions is considered for accurately predicting radiative heat transfer. A solar absorber tube filled with anisotropic scattering working medium is used as an example. Analysis of previous normalization techniques show that while they do conserve scattered energy exactly after DOM discretization, the overall asymmetry factor of the phase function is distorted, leading to substantial changes in overall scattering effect. An innovative normalization technique which conserves asymmetry factor and scattered energy simultaneously is investigated. The impact of lack of asymmetry factor conservation is analyzed for both the Legendre polynomial and HG phase function approximations. Heat flux at the surface and energy absorbing rate inside the solar absorber tube are predicted using the new normalization technique. Variations of medium optical thickness, scattering albedo, asymmetry factor, and side wall emissivity are scrutinized to determine the effect of said parameters on wall heat flux and energy absorbing rate inside the absorber tube. Side wall heat flux is found to increase with increases in asymmetry factor, optical thickness, and wall emissivity, and with decreases in scattering albedo. Energy absorbing rate profiles are found to depend greatly on optical thickness and scattering albedo.
The Claim-making of the Islamist Hizb-ut-Tahrir and the Radical Right-wing party NPD in the Federal Republic of Germany

description: The events of September 11th 2001 increased the attention of Western public towards religious activism in Germany. In fact, this country had become a shelter for radicalized Islamic activists involved in the terrorist attacks. At the same time, the growing domestic violence performed by organized right-wing activists urged the German state to increase pressure on the German right-wing movement. In part, these attacks were related to a terrorist cell called National Socialist Underground (NSU). This cell is said to be closely related to the National Democratic Party of Germany (Nationaldemokratische Partei Deutschlands, hereinafter NPD). Since then, the public debate about migration, Islam and the German society has undergone significant changes while the government of the Federal Republic has become interested in controlling and labeling each protest movement, whichever their affiliation may be, left, right or religious. In the case of the Islamist movement Hizb-ut-tahrir (Party of Liberation), this resulted in the banning of its activities from the country. The NPD, although still legal, barely survived an authority ban attempt in 2003. The dissertation’s main research question is how repression by the state affects the Protest mobilization, in particular public communication, of the Right-wing and the Islamist movements. More specifically, the goal is to see how these movements mobilize within changing conditions of the political environment, namely in the presence, or absence, of a more or less serious possibility of legal banning, which obviously would exert a significant deal of pressure on the movement.  The claim-making that the Islamist and radical right-wing movement address to the public and their adherents constitutes the unit of analysis of this thesis. In order to define these claims, it is necessary to document protest claims and actions within the selected time frame, which covers the period between 2000 and 2011. The data set is mainly consisting of publications, articles and documents released by both movements.

description: Asthma is one of the most common medical complications of pregnancy. Control of asthma is associated with improved perinatal outcomes compared with pregnancies of women whose asthma is not controlled. Peak flow measures have been recommended to determine the status of asthma yet norms for peak flow values in women with asthma are missing from the literature. The purpose of this prospective, longitudinal study was to determine average peak flow values in pregnant women with asthma. Forty three women were recruited into the study prior to the twentieth week of pregnancy. Demographic data including age, ethnic background, and number of pregnancies were collected. Type and severity of asthma, medications used for asthma, and past hospitalizations for asthma was recorded. Peak flow values increased across the three trimesters. Significant differences were found in peak flow values between the first and third trimesters (>0.001) and the second and third trimesters (>0.007). Findings from the present study contradict those of studies on pregnant women without asthma. Since hormonal levels change during pregnancy and hormones are thought to influence the status of asthma, the interaction of hormonal changes of pregnancy and asthma warrant further study.

description: The aim of this paper is to propose a general nonparametric model to estimate latent variables with scores non indeterminate; in this paper, following other approaches (PLS, RCD, RCDR), a latent variable (LV) is conceived as a linear combination of predictors (causes) which best predicts a set of dependent variables (indicators), maximising, in this manner, all available information about a LV in the soecified model. The model is also extented to categorical variables (nominal, ordinal) by means of optimal scaling methodology and applied to the estimate of a bidimensional LV as a proxy of human capital for US families in 1983.

description: Abdi Samatar, current African Studies Association president and professor at the University of Minnesota's Department of Geography, Environment and Society, discusses politics and piracy in Somalia. To start, he problematizes the way in which piracy has been conventionally framed by the media. He follows by reviewing comparative rates of global piracy over the past two decades, explaining conditions that typically exist in areas that experience such activity. To understand piracy in Somalia, Abdi Samatar stresses the need to understand the causes behind the collapse of the Somali government in 1991. He then categorizes the types of piracy found around Somalia and explains economic effects each type of piracy has on local, national and international scales. He closes by positing alternative solutions to decrease piracy off the Somali coast.
Storia del pensiero statistico con alcune osservazioni sull'insegnamento della statistica

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

description: Statistical thinking changed in a striking way since its birth. From the descriptive statistics, linked up the research of statistical regularity, until the investigative statistics in the first part of XX century. Successively, the change was much quicker. First of all, statisticians put sampling and inference as the central core of the matter. Fisher came up with a revolutionary idea to solve the problem of inductive reasoning, by preliminarily designing the experiments in the process of data generation. However, Fisher's inference was no longer probabilistic, involving conclusions and choices which are outside the scope of probability theory. Then, Neyman substituted inductive behavior for Fisher's inductive reasoning, who he considered as a basic concept of philosophy of science. Later on, Neyman's ideas were further developed by Wald, who, in turn, transformed statistics in decision theory. Finally, Savage logically supported the Bayesian paradigm, prominent in all Statistics. Recently, statisticians promoted some pedagogical reasons to hesitate in introducing Bayesian paradigm to beginners. In particular, they placed variability (or "variation") as the essential mark in statistical teaching and in empirical enquiry, linked up a revaluation of the causal research and even of the old investigative statistics. The present paper compares the development of statistical thinking with respect to the similar change in philosophy of science from Galileo and Bacon until nowadays. Besides, it suggests coming back in placing phenomena considered from a non-deterministic viewpoint (collective phenomena) as the study subject of the matter, with a revaluation of all phases of statistical method, from the initial definition of a phenomenon until the final decision. Likewise, the essential mark in statistical teaching should be the method of scientific research rather than the pure and simple study of variation.

description: Firm internationalisation has been enduringly related to competitiveness, while the lack of internationalisation has been used as an indicator of limited competitiveness. However, the implications of withdrawing from international markets on competitiveness have mostly remained absent from the mainstream debate in international business. This paper presents a systematic review of literature on firm de-internationalisation, particularly focussing on its motives and symptoms, in contemporary scholarly discussion. The results show that competitiveness is not adequately conceptualised in de-internationalisation research, opening a gap for further scholarly enquiry

We first present a general definition of risk as the probability of an adverse event over a random distribution and we then introduce a measure of market risk (b-VaR) that admits the traditional b of an asset in portfolio management as a special case when asset returns are normally distributed. Empirical evidences are provided by using Italian stock market data.

description: The differential diagnosis of lesions arising in the broad ligament is quite large. Many of these lesions can be clinically interpreted prior to surgery as adnexal or uterine neoplasms. While some lesions are similar to those arising in other Müllerian sites, there are unique lesions as well. The lesions are uncommon, and may prove challenging to clinicians. The purpose was to review the scope of lesions affecting the broad ligament. A literature review was conducted. A Medline search was used, using the terms broad ligament, mesosalpinx, and mesovarium. A review of the scope of broad ligament lesions is presented to assist in developing a differential diagnosis if a patient with such a lesion is encountered.

Medicine--Study and teaching

description: Medical school teaching is a skill that is very often learned on the job. The faculty comprised of researchers and clinicians are expert in many biomedical disciplines, but familiarity with learning theories and pedagogy are usually not included in their knowledge and skill sets. The pressure to see patients and acquire extramural funding leaves little time for faculty to learn how to teach. When coupled with the natural attrition of senior faculty it is necessary to start junior faculty on the correct path to being effective medical educators who are capable of lecturing and facilitating. Institutions cannot afford to have medical educators learn through trial and error. The standards set by the Liaison Committee on Medical Education (LCME) are also creating an urgency to produce competent teachers as quickly as possible. Novice teachers need to be able to use these standards to align their teaching with goals, objectives and the appropriate pedagogy. This article is designed to be a self-directed guide describing some essentials that a newly hired faculty member can quickly use to get started. An institutional faculty development program can then serve to build upon and enrich the experience for the new faculty member.
Settling human rights violations
Creators: name: Contesse, Jorge
Publisher: name: Rutgers University
Year: 2019

description: In the past few decades, human rights courts have been widely established around the world, sparking the interest of legal scholars who devote significant attention to state accountability for human rights violations. Academic centers exclusively dedicated to the study of international courts have appeared, and conferences on the role of international adjudication now abound. International law has become a juricentric discipline. With the enormous attention afforded to the international human rights judiciary, critical aspects of non-judicial human rights decision-making are often neglected. One understudied mechanism is that of friendly settlements, whereby victims of human rights violations, acting under the “good offices” of regional human rights bodies, enter into direct negotiations with respondent states toward a consensual resolution to a human rights dispute. Despite its prolific use in regional human rights regimes, legal scholars have largely neglected the friendly settlement mechanism. This Article fills that gap. Drawing on a review of all friendly settlements executed before the Inter-American Commission on Human Rights, as well as interviews with Commission personnel (including two of its former presidents), state officials from six Latin American countries, members of non-governmental organizations, and petitioners, this Article comprehensively analyzes the general practice of settling human rights disputes. The Article identifies various motivations underlying the practice: states avoid the “naming and shaming” that comes with human rights litigiousness; victims more quickly obtain reparations; and human rights bodies alleviate their backlog. But friendly settlements also raise serious--and unnoticed--challenges. The Article unearths both normative and practical concerns with settling human rights violations and considers a novel alternative. It proposes an improved form of friendly settlement that (i) distinguishes between and affords differentiated procedural treatment to disputes concerning individual violations and those seeking structural remedies, and (ii) delegates negotiation and compliance functions to local authorities. With these improvements, the Article concludes, human rights settlements can play a critical role in holding states accountable, along with--and even more than--human rights adjudication.

Polygenic risk score
Gail model
Protein-truncating variants
Risk-based screening

description: BACKGROUND: Family history, and genetic and non-genetic risk factors can stratify women according to their individual risk of developing breast cancer. The extent of overlap between these risk predictors is not clear. METHODS: In this case-only analysis involving 7600 Asian breast cancer patients diagnosed between age 30 and 75 years, we examined identification of high-risk patients based on positive family history, the Gail model 5-year absolute risk [5yAR] above 1.3%, breast cancer predisposition genes (protein-truncating variants [PTV] in ATM, BRCA1, BRCA2, CHEK2, PALB2, BARD1, RAD51C, RAD51D, or TP53), and polygenic risk score (PRS) 5yAR above 1.3%. RESULTS: Correlation between 5yAR (at age of diagnosis) predicted by PRS and the Gail model was low (r=0.27). Fifty-three percent of breast cancer patients (n=4041) were considered high risk by one or more classification criteria. Positive family history, PTV carriership, PRS, or the Gail model identified 1247 (16%), 385 (5%), 2774 (36%), and 1592 (21%) patients who were considered at high risk, respectively. In a subset of 3227 women aged below 50 years, the four models studied identified 470 (15%), 213 (7%), 769 (24%), and 325 (10%) unique patients who were considered at high risk, respectively. For younger women, PRS and PTVs together identified 745 (59% of 1276) high-risk individuals who were not identified by the Gail model or family history. CONCLUSIONS: Family history and genetic and non-genetic risk stratification tools have the potential to complement one another to identify women at high risk.

description: Integrins are a family of transmembrane proteins, involved in substrate recognition and cell adhesion in cross-talk with the extra cellular matrix. In this study, we investigated the influence of integrin α2β1 on tendons, another collagen type I-rich tissue of the musculoskeletal system. Morphological, as well as functional, parameters were analyzed in vivo and in vitro, comparing wild-type against integrin α2β1 deficiency. Tenocytes lacking integrin α2β1 produced more collagen in vitro, which is similar to the situation in osseous tissue. Fibril morphology and biomechanical strength proved to be altered, as integrin α2β1 deficiency led to significantly smaller fibrils as well as changes in dynamic E-modulus in vivo. This discrepancy can be explained by a higher collagen turnover: integrin α2β1-deficient cells produced more matrix, and tendons contained more residual C-terminal fragments of type I collagen, as well as an increased matrix metalloproteinase-2 activity. A greatly decreased percentage of non-collagenous proteins may be the cause of changes in fibril diameter regulation and increased the proteolytic degradation of collagen in the integrin-deficient tendons. The results reveal a significant impact of integrin α2β1 on collagen modifications in tendons. Its role in tendon pathologies, like chronic degradation, will be the subject of future investigations.

description: Spin-on processing is used in many industries to deposit very thin coatings on flat substrates, including silicon wafers, flat-panel displays, and precision optical components. A liquid precursor solution is first dispensed onto the surface of the substrate; this fluid then spreads out very evenly over the surface due to large rotational forces caused by spinning of the substrate. When looking for an optimum coating procedure process engineers can adjust many variables including the peak spin speed, the ramping rate to reach that speed, the spinning time, as well as allowing for dynamic solution dispense before ramping up, though most protocols focus on the peak spin speed as the primary controlling variable. Engineers often construct spin-speed versus thickness correlations that enable predictable adjustment of spin-speed to achieve a desired thickness. Yet, rather little attention has been paid to the importance of the acceleration rate used to reach the desired peak speed. We show here that ramping rate is also important in helping establish the final coating thickness. We present a numerical model of the fluid flow on a spinning wafer when the spin-speed is ramping linearly up to a desired peak speed and then held constant. It is shown that the coating may “set” into its final thickness before the spin-speed reaches its peak value. In these cases then the peak spin-speed parameter is no longer the primary variable that defines the final coating thickness. This also impacts the interpretation of critical exponents found when fitting spin-speed vs. thickness data. We perform parallel experimental measurements for different ramping-up times and confirm the results from the numerical model. Both experimental and theoretical results support use of the simplified model put forth by Meyerhofer over 25 years ago (J. Appl. Phys. 49 (1978) 3993-3997).

description: BACKGROUND: Individuals with autism spectrum disorder (ASD) are at particularly high risk of suicide and suicide attempts. Presentation to a hospital with self-harm is one of the strongest risk factors for later suicide. We describe the use of a novel data linkage between routinely collected education data and child and adolescent mental health data to examine whether adolescents with ASD are at higher risk than the general population of presenting to emergency care with self-harm. METHODS: A retrospective cohort study was conducted on the population aged 11-17 resident in four South London boroughs between January 2009 and March 2013, attending state secondary schools, identified in the National Pupil Database (NPD). Exposure data on ASD status were derived from the NPD. We used Cox regression to model time to first self-harm presentation to the Emergency Department (ED). RESULTS: One thousand twenty adolescents presented to the ED with self-harm, and 763 matched to the NPD. The sample for analysis included 113,286 adolescents (2.2% with ASD). For boys only, there was an increased risk of self-harm associated with ASD (adjusted hazard ratio 2·79, 95% CI 1·40-5·57, P<0·01). Several other factors including school absence, exclusion from school and having been in foster care were also associated with a higher risk of self-harm. CONCLUSIONS: This study provides evidence that ASD in boys, and other educational, social and clinical factors, are risk factors for emergency presentation with self-harm in adolescents. These findings are an important step in developing early recognition and prevention programmes.

description: The rational interpolation can be used to correct anomalous values or to add missing values in a distribution of n points. Applying this method it is possible to identify a function passing by any n given points. The function is given by F(x)=S(x)/T(x) where S(x) and T(x) are two rational polynomials in x whose degrees depend on n. In this paper we present an interpolating method and we evaluate the statistical validity of the method here developed with specific application to economical, clinical and environmental data. The results show that the discrepancy between the actual value and the estimate of the same value obtained applying the rational interpolation is lower than 0,1 in 74,5% and 67,6% of cases using respectively economical and environmental data, while using clinical data the discrepancy is lower than 1 in 91% of cases.

description: Endometrial stromal tumor with sex cord- like elements (ESTSCLE) is a rare entity which shares similar histological features with uterine tumors resembling ovarian sex cord tumors (UTROSCT). Differentiating the two entities involves ample sampling of the tissue to distinguish the percentage of sex- cord components within the tissue, genetic studies and immunohistochemical staining. Frozen section provides limited information for exclusion of either tumor; and the tumor is rare enough that the diagnosis may not be considered with the limited sampling; therefore deferral of diagnosis to permanent sections may be appropriate.
Un teorema di rappresentazione per lo stimatore vincolato

description: A recent result in partitioned inversion (Faliva and Zoia, 2000) paves the way to shed some more light on constrained estimation, as the paper shows for the linear model. Indeed, a novel closed-form expression for the restricted least-squares(RLS) estimator is derived, which reads as a mirror image of the well-known Theil's(1961) solution and actually turns out to cover the latter as a special case. This leads eventually to an elegant representation theorem for the RLS estimator which combines classical and new results as well.

Publisher: name: Rutgers University
Year: 1995

description: Determining the type of an object to which a pointer may point at a statement during execution is the goal of static type determination. We prove NP-hardness of type determination and aliasing for C++. We show the interdependence of the two problems for general-purpose pointers and present a polynomial approximation algorithm to solve the combined problem. We include empirical results to demonstrate the feasibility of our analysis.
Tessellation automata with group transformations
Creators: name: Ostrand, Thomas J.
name: Weyuker, Elaine J.
Publisher: name: Rutgers University
Year: 1973

description: A group tessellation automaton (TA) is one whose state alphabet consists of the elements of a group, and whose local transformation is defined in terms of the group's composition rule. If the domain and range of a group TA mapping are restricted to finite configurations, the mapping is one-to-one. On the set of all configurations (including infinite ones), group mappings are onto, but not one-to-one. Questions about the existence of predecessors and successors of configurations, are undecidable for general TA, are constructively solvable for group TA. It is shown that every finite configuration of an arbitrary group TA is self-reproducing. A method of calculating successive generations of abelian group TA configurations is presented, and then used to demonstrate a self-reproduction theorem for abelian group TA. The arithmetical numbers, a generalization of binomial coefficients, are used to derive this result.
Victoria: the natural single-term state?
Creators: name: Rodan, Paul
Publisher: name: Swinburne

description: Victoria could experience two shortlived governments in a row unless Labor can lift its performance in key areas. With an election due in November 2018, the recent downturn in the opinion poll performance of Daniel Andrews’s Labor government might seem like just a blip on Victoria's electoral radar. But if a downward trend were to set in, it wouldn’t be altogether surprising. While Victoria has been a "natural" Labor state for several decades - as reflected in state and national elections – Daniel Andrews’s government has struggled on a number of fronts. It no doubt expects credit for its high-profile investment in infrastructure, but even here the nitty-gritty of choosing and implementing projects invariably produces winners and losers, with the media providing the latter with an abundance of venting opportunities. In the case of one of the biggest-ticket items - the removal of a number of congested road–rail level crossings, with initial focus on the electorally sensitive Frankston corridor - the government will be hoping that memories of temporary inconvenience will have faded by election day, and be replaced by gratitude for a smoother journey. Small businesses devastated by loss of easy customer access to their premises, however temporary, may be less grateful, although Labor cynics might observe that annoyance among this core conservative constituency is unlikely to upset previous voting patterns.
Military electoral authoritarianism in Egypt
Creators: name: Aziz, Sahar F.
Publisher: name: Rutgers University
Year: 2017
Subjects: Egypt--Politics and government

description: This Article begins by providing a theoretical framework for examining the specific ways in which Egypt under Sadat and Mubarak experienced electoral authoritarianism. It then analyzes how election laws and the electoral system were changed after the mass uprisings of January 2011 to liberalize Egypt’s political system. Finally, it focuses on the Sisi era to demonstrate the specific ways election laws have been manipulated to produce a military electoral authoritarian state. Despite the elimination of the dominant National Democratic Party (NDP) from political life, the executive in Egypt continues to control the political system. But now, the military is overtly at the helm of the ruling elite.

description: Maternal immune activation (MIA) is mediated by activation of inflammatory pathways resulting in increased levels of cytokines and chemokines that cross the placental and blood-brain barriers altering fetal neural development. Maternal viral infection is one of the most well-known causes for immune activation in pregnant women. MIA and immune abnormalities are key players in the etiology of developmental conditions such as autism, schizophrenia, ADHD, and depression. Experimental evidence implicating MIA in with different effects in the offspring is complex. For decades, scientists have relied on either MIA models or human epidemiological data or a combination of both. MIA models are generated using infection/pathogenic agents to induce an immunological reaction in rodents and monitor the effects. Human epidemiological studies investigate a link between maternal infection and/or high levels of cytokines in pregnant mothers and the likelihood of developing conditions. In this review, we discuss the importance of understanding the relationship between virus-mediated MIA and neurodevelopmental conditions, focusing on autism and schizophrenia. We further discuss the different methods of studying MIA and their limitations and focus on the different factors contributing to MIA heterogeneity.
Verifica empirica ed analisi critica del modello mistura bivariata

description: Bivariate mixture models, introduced by Tauchen-Pitts, try to esplain the relationship between return volatility and trading volume in financial markets, by stochastic changes in a single latent variable, representing the number of information arrivals. In this article, dynamic bivariate mixture models that allow for autocorrelation in the latent variable are represented by nonlinear state space systems, nonlinearity being due to the measurement equation. The parametres are estimated by simulated maximum likelihood and the latent variable by simulated non linear filter, both being based on the same rejection sampling algorithm. The results, based on italian daily stock market data, reveal that dynamic bivariate mixture models neither can explain the autocorrelation, nor can account for the persistence in return variance.

La stima della media nel campionamento per centri

Year: 2007

description: The "aggregation points" sampling design applies, for instance, in survey of irregular immigrants i.e. of populations composed by a finite but unknown number of units which do not consent labelling and that can be reached only through a set of known but overlapping frames called "aggregation points". Dealing with the "aggregation points" sampling design, the problem of estimating the mean of a quantitative character is concerned; an estimate of the estimator's variance is also proposed. Some results from a simulation study are presented. Simulations indicate that estimators proposed perform better in case of not too large number of aggregation points but extensively overlapping.

Year: 2007

description: This paper outlines some issues in fit assessment and in selection between competitive models in Structural Equation Models(SEM). The theory on chi-square statistic and the results of some simulation studies are reviewed and the methodological consequences are discussed. Several goodnees-of-fit indices are discussed and their employment in fit assessment and in the selection between competitive models are taken into consideration. A Monte Carlo study was used to point out the difficulties connected with model selection in SEM under misspecification. Keywords: structural equation models, LISREL, fit assessment, competitive models, misspecification.

Berry, Wendell, 1934-

description: Rhyme and meter have certainly known their ups and downs in this century... Wendell Berry is part of this generation, and for most of his career he has followed its predilections as to form. It is of some present interest, therefore, that in his most recent book of poems, Sabbaths, he has made a major investment in traditional forms. It is worth considering just what Berry expects to get from formal verse that he could not have gotten from his earlier, free verse forms. Could this be simply a nostalgia for the poetry of his student days, the poetic equivalent of the recent revival of “Greek” life on college campuses, or does it suggest something new and necessary in his expression?

description: This paper explores the behaviour of the ubiquitous twisted pairs at high frequencies and wideband excitation of twisted pairs up to 12 GHz. Higher carrier frequencies on twisted pairs can enable the data rates required by the future communication networks; hence, the existing copper infrastructure can be utilised on the last mile complementing the fibre networks. In this paper, we show a fundamental limit on the operating frequency of twisted pairs beyond which twisted pairs start to radiate and behave like an antenna. To validate our theoretical derivations through measurements, we designed a microstrip balun to excite the differential mode on the twisted pairs. At the end, we demonstrate that the standard twisted pairs used in the UK can be used up to 5 GHz carrier frequency without any radiation effect and this upper-bound can be moved to higher frequencies by decreasing the twist lengths.
