The objective of this work is to establish the reliability of the measurement system by attributes in the color characteristic for the galvanized parts as final product. Six operators were evaluated with 30 samples of galvanized metal parts cold and hot rolled in a proportion of 50% of accepted parts and 50% rejected by the quality staff of the Techengineering plant in the city of Aguascalientes, Aguascalientes, under a criterion of passes-does not pass. To carry out the study, the attribute agreement analysis tool of Minitab®16 was used. According to the Fleiss Kappa coefficient and confidence intervals generated in the report, it was established that the accuracy of the system is valued between excellent and good and the accuracy as good marginally, with this information it was possible to establish strategies to improve the measurement system.

Threshold Measurement

Background: Accurate prescriptive gain results in a more accurate fit, lower return rate in hearing aids, and increased patient satisfaction. In situ threshold measurements can be used to determine required gain. The Widex Corporation uses an in situ threshold measurement strategy, called the Sensogram. Real-ear measurements determine if prescriptive gain targets have been achieved. Starkey Laboratories introduced an integrated real-ear measurement system in their hearing aids. Purpose: To determine whether the responses obtained using the Widex Sensogram were equivalent to those obtained using current clinical threshold measurement methods. To determine the accuracy of the Starkey IREMS™ (Integrated Real Ear Measurement System) in measuring RECD (real-ear to coupler difference) values compared to a dedicated real-ear measurement system. Research Design: A verification design was employed by comparing participant data measured from standard, benchmark equipment and procedures against new techniques offered by hearing-aid manufacturers. Study Sample: A total of 20 participants participated in this study. Ten participants with sensorineural hearing loss were recruited from the Ohio University Hearing, Speech, and Language Clinic participated in the first experiment. Ten participants with normal hearing were recruited from the student population at Ohio University participated in both experiments. The normal-hearing group had thresholds of 15 dB HL or better at the octave frequencies of 250–8000 Hz. The hearing-impaired group had thresholds of varying degrees and configurations with thresholds equal to or poorer than 25 dB HL three-frequency pure-tone average. Data Collection and Analysis: The order of measurement method for both experiments was counterbalanced. In Experiment 1, thresholds obtained via the Widex Sensogram were compared to thresholds obtained for each participant using a clinical audiometer and ER-3A insert ear phones. In Experiment 2, RECD values obtained via the Starkey IREMS were compared to RECD values obtained via the Audioscan Verifit™. A repeated-measures analysis of variance (ANOVA) was used for statistical analysis, and a Fisher's LSD (least significant difference) was used as a post hoc analysis tool. Results: A significant difference between Sensogram thresholds and conventional audiometric thresholds was found with the Sensogram method resulting in better threshold values at 0.5, 1.0, and 2.0 kHz for both groups. In Experiment 2, a significant difference between RECD values obtained by the Starkey IREMS and the Audioscan Verifit system was found with significant differences in RECD values found at 0.25, 0.5, 0.75, 1.5, 2.0, and 6.0 kHz. Conclusions: The Sensogram data differ significantly from traditional audiometry at several frequencies important for speech intelligibility. Real-ear measures are still required for verification of prescribed gain, however, calling into question any claims of shortened fitting time. The Starkey IREMS does perform real-ear measurements that vary significantly from benchmark equipment. These technologies represent a positive direction in prescribing accurate gain during hearing-aid fittings, but a stand-alone system is still the preferred method for real-ear measurements in hearing-aid fittings.

The percentual distributions of selected sites of cancer cases according to origin, sex and age are compared. Data were obtained from the Registry of Cancer of S. Paulo (School of Public Health of the University of S. Paulo, Brazil). The reference period for inhabitants of Japanese descent was 1969/78 and for those of Brazilian descent, the period was 1969/75. Standardized Proportionate Incidence Ratios (SPIR) with approximate 95% Confidence Intervals (CI) were evaluated using age specific Incidence Ratios of S. Paulo, 1973, as standards. The results agree with findings of previous works on mortality, but show different patterns according to origin. The well known fact that some sub-groups of a population may be different from the overall group is once again brought to the fore. Attention should be drawn to the differences detected for stomach, skin and prostate, in males, and for stomach, skin, cervix and uterus in females.

Information about the land use of built-up areas is required for the comprehensive planning and management of cities. However, due to the high cost of the land use surveys, land use data is out-dated or not available for many cities. Therefore, we propose the reuse of up-to-date and low-cost place data from social media applications for land use mapping purposes. As main case study, we used Foursquare place data for estimating nonresidential building block use in the city of Amsterdam. Based on the Foursquare place categories, we estimated the use of 9827 building blocks, and we compared the classification results with a reference building block use dataset. Our evaluation metric is the kappa coefficient, which determines if the classification results are significantly better than a random guess result. Using the optimal set of parameter values, we achieved the highest kappa coefficient values for the land use categories “ hotels, restaurants and cafes” (0.76) and “ retail” (0.65). The lowest kappa coefficients were found for the land use categories “ industries” and “ storage and unclear”. We have also applied the methodology in another case study area, the city of Varese in Italy, where we had similar accuracy results. We therefore conclude that Foursquare place data can be trusted only for the estimation of particular land use categories.

One of the most celebrated findings in complex systems in the last decade is that different indexes y (e.g. patents) scale nonlinearly with the population x of the cities in which they appear, i.e. y ∼ x β , β ≠1. More recently, the generality of this finding has been questioned in studies that used new databases and different definitions of city boundaries. In this paper, we investigate the existence of nonlinear scaling, using a probabilistic framework in which fluctuations are accounted for explicitly. In particular, we show that this allows not only to (i) estimate β and confidence intervals, but also to (ii) quantify the evidence in favour of β ≠1 and (iii) test the hypothesis that the observations are compatible with the nonlinear scaling. We employ this framework to compare five different models to 15 different datasets and we find that the answers to points (i)–(iii) crucially depend on the fluctuations contained in the data, on how they are modelled, and on the fact that the city sizes are heavy-tailed distributed.

The purpose of this study was to conduct an assessment of Allan Gardens' urban forest and to investigate the value of environmental and aesthetic benefits it provides the City of Toronto. This project used the Street Tree Resource Analysis Tool for Urban Forest Managers (STRATUM) model to assess forest structure, function, and monetary value of benefits. Soil in Allan Gardens was also investigated to determine the growing conditions for park trees. Results indicate that Allan Gardens maintained 309 trees that provide $60,407 annually in net annual environmental and property value benefits to the City of Toronto. Soil conditions in the park were found to be highly variable, where some locations were highly compacted and may be restricting tree root growth. To sustain and enhance these benefits in the future, Toronto's urban forest requires dedicated management and maintenance that includes new plantings, but prioritized protection and maintenance of existing trees and soil.

Introducción: Esta investigación ajusta un modelo para la prevalencia del Síndrome Metabólico y, evalúa el nivel de acuerdo en la clasificación de la población general, área metropolitana, municipio Libertador de la ciudad de Mérida, Venezuela, 2005, según las variables PREV1 y PREV2, diseñadas empleando criterios de NCPE-ATP III. Materiales y Métodos: Se propone el uso del coeficiente kappa de Cohen para medir dicho acuerdo. Se emplea el procedimiento propuesto por Nava y Sinha (2007), para ajustar un modelo de regresión logística que relaciona la prevalencia de Síndrome Metabólico (SM), también conocido como Síndrome X, con las variables sexo, talla, peso, índice de masa corporal (IMC), alcohol, tabaco, sedentarismo, glucosa, HDL, triglicéridos, obesidad, clase social, edad y estado civil; considerando información referente a un grupo de 275 habitantes. Resultados discusión: Los resultados indican que las variables relacionadas en forma significativa con la presencia de SM son sexo, IMC, glucosa, HDL, triglicéridos y edad. Glucosa, HDL, triglicéridos e índice de masa corporal corregido, son variables que incrementan en forma significativa las posibilidades de prevalencia de SM. Conclusiones: Se concluye, que las mujeres tienen mayores posibilidades que los hombres de presentar SM; el valor obtenido para el coeficiente kappa de Cohen, indica que existe un alto acuerdo en la clasificación de los individuos considerados en la investigación según las variables PREV1 y PREV2, es decir, cualquiera de esas variables puede usarse para determinar la prevalencia de SM.Introduction: This research sets a model for the prevalence of Metabolic Syndrome and evaluates the level of agreement in the classification of the general population, metropolitan area, Libertador municipality of the city of Mérida, Venezuela, 2005, according to variables PREV1 and PREV2, designed using the criteria of theNCPEATPIII. Materials and methods: We propose the use of Cohen’s kappa coefficient to measure this deal. This paper uses the proposed procedure by Nava and Sinha (2007), to fit a logistic regression model that relates the prevalence of metabolic syndrome (MS) or syndrome X, with the variables sex, height, weight, CBMI, alcohol, snuff, sedentary lifestyle, glucose, HDL, triglycerides, obesity, social class, age and marital status, considering information on a group of 275 people. Results and discussion: Results shows that the variables significantly associated with the presence of MS are sex, CBMI, glucose, HDL, triglycerides and age. Glucose, HDL, triglycerides and CBMI, are variables that increases significantly the chances of prevalence of MS. Conclusions: We conclude that women are more likely than men to have SM; the value obtained for the Cohen kappa coefficient, indicate a high agreement on the classification of individuals considered in the investigation according to the variables PREV1 and PREV2, i.e. any of these variables can be used to determine the prevalence of MS.

Representative Samples

The present article analyses a classic in the methodology on the analysis of the social variation of languages: the application of the ratio of 0'0025 % to obtain a representative sample of the population of a speaking community. This ratio, established empirically by Labov in 1966 for New York City, nevertheless presents important limitations when moving to communities with smaller populations. Replicating the empirical experimentation in four Spanish populations of different demographic size, it is shown that the empirically representative samples correspond to the confidence intervals already provided by the general statistics. Likewise, it is shown that these were the parameters between which 0,0025 % in the city of New York was developed. Consequently, the problem was not in the formulation of the ratio by Labov (1966), but in the subsequent indiscriminate application that has been made of it.
