Resumen

Objective: To assess the prevalence of congenital defects and to investigate their maternal and perinatal associated aspects by reviewing Birth Certificates. Methods: Among all born alive infants from January 2003 to December 2007 in Maternidade da Santa Casa de Misericórdia of São Carlos, Southeast Brazil (12,199 infants), cases were identified as the newborns whose Birth Certificates registered any congenital defect. The same sex neonate born immediately after the case was chosen as a control. In total, 13 variables were analyzed: six were maternal related, three represented labor and delivery conditions and four were linked to fetal status. The chi-square and Fisher's exact tests were used to compare the variables, being significant p<0.05. Results: The prevalence of congenital defects was 0.38% and the association of two or more defects represented 32% of all cases. The number of mothers whose education level was equal or less than eight years was significantly higher among the group with birth defects (p=0.047). A higher frequency of prematurity (p<0.001) and cesarean delivery (p=0.004) was observed among children with birth defects. This group also showed lower birth weight and Apgar scores in the 1st and the 5th minute (p<0.001). Conclusions: The prevalence of congenital defect of 0.38% is possibly due to underreporting. The defects notified in the Birth Certificates were only the most visible ones, regardless of their severity. There is a need of adequate epidemiological monitoring of birth defects in order to create and expand prevention and treatment programs.

Resumen

Objective: To (a) determine the impact of Kentucky’s (KY’s) mandate requiring postmortem toxicology testing of coroner cases; (b) identify the influence of coroner experience and training, jurisdiction size, budget, and location on postmortem testing requests; (c) identify facilitators/barriers for postmortem toxicology testing requests and listing the specific drugs involved in drug-poisoning deaths on death certificates. Methods: A modified Dillman approach was used to deliver the survey to KY’s elected coroners between April and May 2016. Responses stratified by identified influence factors were compared using χ2 tests and Fisher exact tests. Results: Fifty-eight percent of coroners reported that drug overdose investigations had changed since the mandate was enacted. Statistically significant differences in responses were found when stratified. Sixty-three percent of coroners reported always using testing results to complete death certificates. Conclusions: Uptake of the mandate for postmortem toxicology testing of all decedents is not yet complete. Policy Implication: Without uptake of the mandate, surveillance efforts may result in undercounting of drug overdose deaths and the involvement of specific drugs. Mandates for enhanced training and modification of funding structure for medico-legal death investigations could facilitate uptake.

Resumen

Often---for example in war games, strategy video games, and financial simulations---the game is given to us only as a black-box simulator in which we can play it. In these settings, since the game may have unknown nature action distributions (from which we can only obtain samples) and/or be too large to expand fully, it can be difficult to compute strategies with guarantees on exploitability. Recent work (Zhang and Sandholm 2020) resulted in a notion of certificate for extensive-form games that allows exploitability guarantees while not expanding the full game tree. However, that work assumed that the black box could sample or expand arbitrary nodes of the game tree at any time, and that a series of exact game solves (via, for example, linear programming) can be conducted to compute the certificate. Each of those two assumptions severely restricts the practical applicability of that method. In this work, we relax both of the assumptions. We show that high-probability certificates can be obtained with a black box that can do nothing more than play through games, using only a regret minimizer as a subroutine. As a bonus, we obtain an equilibrium-finding algorithm with $\tilde O(1/\sqrt{T})$ convergence rate in the extensive-form game setting that does not rely on a sampling strategy with lower-bounded reach probabilities (which MCCFR assumes). We demonstrate experimentally that, in the black-box setting, our methods are able to provide nontrivial exploitability guarantees while expanding only a small fraction of the game tree.

Resumen

Modern ship simulators enable simulations of reality using available environment and ship models. When choosing a specific vessel from a catalogue, however, it is not always immediately apparent as to how true a simulation is to the original vessel. Its makers are required only to have software certificates, which does not ensure the exact modelling of a ship in the simulation. This paper presents research in continuation of previous work presenting a general methodology for the evaluation of the degree of accuracy of a simulated ship model compared to its real-world counterpart. In this paper, the results are shown of a comparative analysis based on actual measurements with the use of one of the methods of multi-criteria analysis. Furthermore, the methodology for the construction of ship models is presented. The paper concludes with a test verifying the accuracy of the assumptions.

Resumen

Abstract Construction waste makes up a large part of the waste produced in Europe. Therefore, the European Commission has developed policies to create an economic cycle and increase waste recycling. These solutions have been developed reduce the destructive effects of the environment, including various certificates such as LEED in different countries to encourage building debris management. However, not all construction waste can be recycled and reused, often buried in the environment. Although these wastes are extracted from natural resources, the process of making them changes their original nature, and it is not possible to estimate the exact time of their decomposition and reversibility of waste in nature. Thus, a large part of them is landfilled due to their Non-Recyclability. Moreover, every year, a large area of fertile and usable land is allocated for their burial. This paper aims to clarify the non-recyclable part of landfilled construction waste in the environment, highlighting the need for importance and research in this area. It can improve and preserve the sources, land, and health of the environment and human beings in EU member states threatened by landfilling.

Resumen

The purpose of the study is to determine the actual demand for the elimination of architectural barriers among senior citizens in their place of residence and also in its immediate environment in Poland. The research covered a group of people in the post-productive age, living in the Lower Silesia voivodship in Poland. Different research methods were used in the study, primarily including the public opinion survey based on a questionnaire as well as statistical analyses. The cross-tabulation analysis of differences in quality characteristics was performed using Pearson’s chi-square test (χ2 test of independence) or Fisher’s exact test, when the expected number was lower than five. As a post hoc analysis, checking the nature of differences between the studied groups, the analyses were carried out using the method by Baesley and Schumacker. For all analyses, the maximum permissible error class I α = 0.05 was adopted, whereas p ≤ 0.05 was considered statistically significant. The research revealed that a much larger group of people aged 55 and older suffers from mobility limitations than the ones resulting from disability certificates, thus confirming the assumption that along with the respondents’ age, their mobility limitations intensify, resulting in the need for assistance while moving outside their houses/apartments.

Resumen

Examining the consequences of the First World War, it can be concluded that its impact on the demographic conditions was significant. In addition to the national data it is important to examine them on local level, too. Based on these studies interesting data have been found. Therefore, I have decided to examine the 20th century history of my hometown, Gyomaendrõd in detail. (It is important to note that during the investigated period Gyoma and Endrõd were two separate villages.) Gyoma village is a traditional lowland settlement which is located in Bekes County. Based on the 1910 census, 11 699 people lived in Gyoma. The denominational share of Gyoma in 1910 shows a Calvinistic majority (74%), Catholic (15%) and Lutheran (8,5%) minority. If the nationalities are examined, it can be noticed that 94% of the population is of Hungarian nationality, while there is a 5% German minority. In my research I set two main objectives: Firstly, I will clarify how many of the men enlisted from the settlement died, where, when and in which corps. Based on the exact war loss and official statistics it will be shown how it led to social, demographic and economic changes in the life of the village. For my research I used documents found in the Békés County Archives of Békési Branch Archives, more precisely the death certificates were used as primary resources.

Resumen

Abstract Introduction: Combination of standard chemotherapy with Rituximab led to improved disease control in pts. with B-cell lymphoma and a clearcut survival benefit in diffuse large B cell lymphoma (DLBCL) in a multitude of clinical trials. We wanted to know, if a similar benefit could be demonstrated in the routine follow-up data of the regional population-based cancer registry of the Regensburg cancer center (“Tumorzentrum Regensburg”, TUZ). The TUZ spreads evidence-based treatment recommendations, but beyond this, treatments are performed according to the discretion of individual physicians and institutions. Methods: We searched the registry for B-NHL diagnosed between 1998 and 2005 entered as DLBCL, mantle cell lymphoma (MCL), follicular lymphoma (FL), undefined low grade lymphoma and corresponding terms from the ICD-O3. Furthermore, death certificates were systematically matched to the patient data and additionally searched for the terms C82, 83, 85, 88 of the ICD-10. Using these data, we compared overall survival of patients receiving any first line chemotherapy plus rituximab and patients receiving chemotherapy alone. Results: Comparing registry data to death certificates an 85% coverage of lymphoma patients within the registry can be estimated. In the high grade lymphoma group, 450 patients have been entered into the registry. Of these, 49 were insufficiently documented, 29 patients had a delayed start of their treatment and 41 received no chemotherapy at all. 122 pts. received rituximab-containing chemotherapy resulting in a 2 year survival of 87%, whereas 209 pts. received chemotherapy alone with a significantly inferior 2 year survival of 70%, p=0,004 by log rank test (fig). 307 pts with low grade lymphoma were found. Of these, 31 were insufficiently documented. 84 pts. did not receive any therapy at all during the observation period and showed the best survival as expected (watch and wait). 69 and 123 pts. received first line chemotherapy with or without Rituximab, respectively. Regarding all low grade NHL together, no significant difference was found, however, FL pts. survived longer, when Rituximab was given (2 year survival 91% vs. 72%, p=0,046). Conclusions: A survival benefit comparable to the results within clinical trials can be observed in registry data in an unsupervised community setting for patients with DLBCL treated first line with a Rituximab containing chemotherapy. A strong trend for improved survival was also observed for FL. These data confirm the standard use of Rituximab as first line therapy in DLBCL and FL and they support the collection of an extended set of treatment data containing exact descriptions of systemic therapy in cancer registries in order to answer similar questions in the future.

Resumen

By the 1930s, the power of birth certificates to determine the facts of a person’s identity (name, parentage, exact age, sex, and race) was well-established. The increased use of birth certificates as instruments of identification coincided with the administrative use of blood-quantum to distribute (and block) access to the goods of citizenship. This was true both in federal Indian policy and state-based Jim Crow segregation. This made vital documents attractive to the architects of a racial order who sought not only to enforce segregation but also to impose a black-white order on the racially ambiguous, racially-mixed communities scattered throughout the South. Because state Bureaus of Vital Statistics possessed the ability to racially classify individuals on their birth documents, they were able to redefine the racial landscape. In the case of Jim Crow-era Virginia, state officials did this by denying babies and their parents access to the racial category of “Indian” and foreclosing all the state and federal recognition that entailed.

Resumen

Marvell held on to his poetic manuscripts more tightly than even the most print-shy of early modern poets. We would not know most of them now but for the seeming happenstance of their being printed in 1681, as Mary Marvell puts it in her prefixed certificate, ‘according to the exact Copies of my late dear Husband, under his own Hand-Writing, being found since his Death among his other Papers’. This chapter considers anew the transmission of Marvell’s poetry, asking what can be inferred about those ‘exact Copies’ (which did not survive the printing process) from two artefacts in particular. The first is Miscellaneous Poems (1681) itself. The other is MS Eng. Poet. d. 49, an annotated and supplemented copy of Miscellaneous Poems better known today as the ‘Popple’ manuscript. What do they tell us about what lay behind them? Are any traces of Marvell’s autograph verse visible notwithstanding printing house interventions? And to what extent does d. 49 replicate the Marvellian archive from which it was being prepared? In the absence of Marvell’s literary autographs, scholars have no alternative but to undertake such conjectural reconstructions.

Resumen

This chapter provides data regarding Cornelius Hodges’s birth and traces his family history to his grandparents’ generation. Confusion as to the exact spelling of his last name (“Hodges,” not “Hodge”) is resolved by reference to his birth certificate. Census records reveal that, contrary to prior accounts of his life, he had not one sister but three, all older. The change in his name from “Cornelius” to “Johnny” is discussed, along with the seven nicknames that he was given by colleagues. The chapter also details the history of the Cambridge, Massachusetts, neighborhood where he was born—Cambridgeport—and of the South End of Boston, to which the family would move when he was twelve, after a stop in North Cambridge that has been overlooked in prior accounts of his life.

Resumen

Security is a critical issue in modern power system operation. With the aid of analytic tools for large-scale and hybrid systems, this paper proposes two new safety verification methods for power systems. The first method is based on barrier certificates and passivity. This method provides a general safety verification framework for power systems with the port-Hamiltonian structure. The energy shaping technique is also exploited to attain safety conditions for controlled port-Hamiltonian systems. The second method, based on positive invariance, yields exact safety verification for power systems based on linearized models, particularly linear Hamiltonian systems. Decidability of exact safety verification is established via algebraic and positive invariance approaches; other analytic and numerical issues are addressed from the positive invariance perspective.

Resumen

The everyday consumption of household goods is a significant source of environmental pollution. The increase of online shopping affords an opportunity to provide consumers with actionable feedback on the social and environmental impact of potential purchases, at the exact moment when it is relevant. Unfortunately, consumers are inundated with ambiguous sustainability information. For example, greenwashing can make it difficult to identify environmentally friendly products. The highest-quality options, such as Life Cycle Assessment (LCA) scores or tailored impact certificates (e.g., environmentally friendly tags), designed for assessing the environmental impact of consumption, are ineffective in the setting of online shopping. They are simply too costly to provide a feasible solution when scaled up, and often rely on data from self-interested market players. We contribute an analysis of this online environment, exploring how the dynamic between sellers and consumers surfaces claims and concerns regarding sustainable consumption. In order to better provide information to consumers, we propose a machine learning method that can discover signals of sustainability from these interactions. Our method, SustainableSignals, is a first step in scaling up the provision of sustainability cues to online consumers.

Texto completo

Resumen

In many cases, the declaration of compliance of a result of measurement is not clear. This is observed when there is a partial superposition of the expanded uncertainty of a quantity with its limit of specification. In these cases, a judgment is required based in pre-established criteria between the client and the supplier. The consequences of an inadequate decision may be disastrous. Either the supplier will have financial losses or it will lose credibility with its client. This work demonstrates how to calculate the probability, for an appropriate confidence level, that the uncertainty associated with the measurement is within the limits that were established in a contract, declaring the compliance or non-compliance relative to the specification, and study two methodologies for helping the claimer to take the decision of compliance or non-compliance, using as example the heat capacity of natural gas, calculated from its gas chromatography. This approach encourages the client/supplier relationship. This occurs because the results are reported to both parts with a probability of compliance instead of a single value. The first methodology is based on the increase in the size of the sample. The second proposal is based in the calibration of the chromatograph against certificate reference materials with more exact and precise uncertainty values.
