Abstract The quality of a dataset used for evaluating data linking methods, techniques, and tools depends on the availability of a set of mappings, called reference alignment, that is known to be correct. In particular, it is crucial that mappings effectively represent relations between pairs of entities that are indeed similar due to the fact that they denote the same object. Since the reliability of mappings is decisive in order to perform a fair evaluation of automatic linking methods and tools, we call this property of mappings as mapping fairness. In this article, we propose a crowd-based approach, called Crowd Quality (CQ), for assessing the quality of data linking datasets by measuring the fairness of the mappings in the reference alignment. Moreover, we present a real experiment, where we evaluate two state-of-the-art data linking tools before and after the refinement of the reference alignment based on the CQ approach, in order to present the benefits deriving from the crowd assessment of mapping fairness.

Guided by the lens of psychodynamic theory, Ford (2015) investigated the challenges faced by adoptive families of traumatized children. Fifteen families were randomly selected to participate in this study from a group of 30 parents who adopted traumatized children in Arizona. Thematic categories were drawn and summarized. Textual descriptions evolved from the thematic groups acknowledging their experiences and how these lived experiences guided their decision to adopt a traumatized child. Verification techniques, data mining, journaling, clustering, brainstorming, and peer reviews were used to ensure the quality of data. Emergent themes emphasized the need for adoption-focused training specific to traumatized children. Ford's (2015) study revealed that these adoptive families desired to be equipped with specialized therapeutic training before and after their adoptions.

AbstractIn 2002 the International Virtual Observatory Alliance (IVOA) has been created in order to gather efforts on data standardization and dissemination. Since then, the virtual Observatory allowed to spread validated data all over the world and to use data from everywhere from earth. From the standards definitions to development of tools, developers have set up a technical infrastructure used by astronomers to easily search for data and make science with all available products, more tools and more confidence on the quality of data. The goal of this review is to present the state of the art of the VO data, standards and tools. This review focuses on basic astronomer's questions : what kind of data are accessible, how to deal with these data and how to use them.

Background. Universal access to antiretroviral therapy (ARVT) started in Mexico in 2001; no evaluation of the features of ARVT prescriptions over time has been conducted. The aim of the study is to document trends in the quality of ARVT-prescription before and after universal access.Methods. We describe ARVT prescriptions before and after 2001 in three health facilities from the following subsystems: the Mexican Social Security (IMSS), the Ministry of Health (SSA), and National Institutes of Health (INS). Combinations of drugs and reasons for change were classified according to current Mexican guidelines and state-of-the-art therapy. Comparisons were made usingχ2tests.Results. Before 2001, 29% of patients starting ARVT received HAART; after 2001 it increased to 90%. The proportion of adequate prescriptions decreased within the two periods of study in all facilities (Pvalue < 0.01). The INS and SSA were more likely to be prescribed adequately (Pvalue < 0.01) compared to IMSS. The distribution of reasons for change was not significantly different during this time for all facilities (Pvalue > 0.05).Conclusions. Universal ARVT access in Mexico was associated with changes in ARVT-prescription patterns over time. Health providers’ performance improved, but not homogeneously. Training of personnel and guidelines updating is essential to improve prescription.

This study describes the current state of the art related to the assessment of the positional accuracy of spatial databases based on lines. The use of this type of element of spatial databases has increased in recent years because of the current possibilities of acquisition and sharing data of routes, roads, etc. Nowadays, users are also contributors and this supposes that the spatial quality of data acquired and shared by non-experts must be assessed as is the case with data produced by institutions and enterprises. In this context, several methods based on lines have been developed up to this time for several purposes. This study reviews these methods, analyzing their characteristics, measures, etc. In addition, more than 30 applications of these methods are also summarized. These applications include control of generalized and digitized lines, control of spatial databases, analysis of the displacement of lines between dates, etc

This paper describes the results of calculating hospital admission dates by computer using a relatively simple scheduling process. The scheduling process was developed as an extension to an existing computer-assisted waiting list system being used in a department of Urology. Results were obtained by observing the behaviour of the system over periods of 6 months before and after extension, and by running the extended system as part of a simulation model. It is shown that the relatively simple computer scheduling process can be used to satisfactorily replace a substantial part of the former manual scheduling, and that the quality of data present in the computer-assisted waiting list system prior to extension was adequate to support the new process. The extension results in a significant saving of clinicians' time with negligible increase in running costs.

Improve Sleep Quality

Objective: The primary aim of the present study was to compare sleep characteristics pre- and post-move into a state-of-the-art mental health facility, which offered private sleeping quarters. Background: Significant evidence points toward sleep disruption among psychiatric inpatients. It is unclear, however, how environmental factors (e.g., dorm-style rooms) impact sleep quality in this population. Methods: To assess sleep quality, a novel objective technology, actigraphy, was used before and after a facility move. Subjective daily interviews were also administered, along with the Horne–Ostberg Morningness–Eveningness Questionnaire and the Pittsburgh Sleep Quality Index. Results: Actigraphy revealed significant improvements in objective sleep quality following the facility move. Interestingly, subjective report of sleep quality did not correlate with the objective measures. Circadian sleep type appeared to play a role in influencing subjective attitudes toward sleep quality. Conclusions: Built environment has a significant effect on the sleep quality of psychiatric inpatients. Given well-documented disruptions in sleep quality present among psychiatric patients undergoing hospitalization, design elements like single patient bedrooms are highly desirable.

One goal in electron microscopy of biological specimens is to improve the quality of data to equal the resolution capabilities of modem transmission electron microscopes. Radiation damage and beam- induced movement caused by charging of the sample, low image contrast at high resolution, and sensitivity to external vibration and drift in side entry specimen holders limit the effective resolution one can achieve. Several methods have been developed to address these limitations: cryomethods are widely employed to preserve and stabilize specimens against some of the adverse effects of the vacuum and electron beam irradiation, spot-scan imaging reduces charging and associated beam-induced movement, and energy-filtered imaging removes the “fog” caused by inelastic scattering of electrons which is particularly pronounced in thick specimens.Although most cryoholders can easily achieve a 3.4Å resolution specification, information perpendicular to the goniometer axis may be degraded due to vibration. Absolute drift after mechanical and thermal equilibration as well as drift after movement of a holder may cause loss of resolution in any direction.

Better Than

The purpose of this study is (1) to analyze public perception on urban services before and after the expansion of the region, (2) analyze the level of people's satisfaction with urban services, and (3) analyze the determinants of the variables that determine what level of people's satisfaction urban services. This study concluded that first, after the expansion, the quality of urban services in South Tangerang City is better than before. Secondly, however, public satisfaction with the services only reached 48.53% (poor scale). Third, by using a Cartesian Diagram, the second priority that must be addressed are: (1) clarity of service personnel, (2) the discipline of service personnel, (3) responsibility for care workers; (4) the speed of service, (5) the ability of officers services, (6) obtain justice services, and (7) the courtesy and hospitality workers.
