A method for the automated, reliable retrieval of publication-citation records.

Filter 3: vocabulary agreement. As mentioned in the introduction, name uniqueness is not a sufficiently rigorous criterion to discern the publications that belong to a given individual: many individuals share the same name, many more share the same last name and first and middle initials. In light of this fact, we require another criterion to decide which papers belonging to two or more individuals with the same name were actually authored by the individual of interest. A central insight we present in this paper is that of using domain-specific vocabulary to recognize papers belonging to a specific individual. Particularly in science and engineering, the titles of papers contain a significant amount of domain-specific vocabulary which will not appear in any other domain (e.g., names of genes, chemical compounds, and design patterns). We use an individual’s online research statement or publication webpage to define the set of domain-specific terms which will be used. Any candidate publication containing a sufficient number of these terms will be accepted as belonging to the individual’s research area and, therefore, to the individual of interest. It is important to note that this makes the strong assumption that two people who work in areas which share the same domain-specific vocabulary and share the same name are highly unlikely. We acknowledge that this is a potential source of error in our method, though in our validation and in subsequent use of the tool, we have not observed this to be a significant source of error even for very common names. Nonetheless, we identify this issue for consideration in future work.

Recommending automated extract method refactorings

Recommending automated extract method refactorings

However, despite the availability of supporting tools, recent empirical research shows that these tools, especially those supporting Extract Method refactorings, are most of the times underused [Negara et al., 2013; Kim et al., 2012; Murphy-Hill et al., 2012; Murphy-Hill and Black, 2008b]. For example, in a study including developers working in their natural environment, Negara et al. [2013] found that the number of participants who are aware of the automated support for Extract Method but still apply it manually is higher than the number of participants who predominantly apply it automatically. Moreover, a study from Murphy-Hill and Black [2008a] revealed that some users were discouraged to use the Extract Method tool of Eclipse IDE due to usability problems regarding the manual selection of valid code fragments. More im- portant, current tools focus only on automating refactoring application, but developers expend considerable effort on the manual identification of refactoring opportunities.

Testing an Automated Accuracy Assessment Method on Bibliographic Data

Testing an Automated Accuracy Assessment Method on Bibliographic Data

This study investigates automated data accuracy assessment as described in data quality literature for its suitability to assess bibliographic data. The data samples comprise the publications of two Nobel Prize winners in the field of Chemistry for a 10-year-publication period retrieved from the two bibliometric data sources, Web of Science and Scopus. The bibliographic records are assessed against the original publication (gold standard) and an automatic assessment method is compared to a manual one. The results show that the manual assessment method reflects truer accuracy scores. The automated assessment method would need to be extended by additional rules that reflect specific characteristics of bibliographic data. Both data sources had higher accuracy scores per field than accumulated per record. This study contributes to the research on finding a standardized assessment method of bibliographic data accuracy as well as defining the impact of data accuracy on the citation matching process.

Vanevar Bush in 1945, was the first author to propose the method of collection, organization and retrieval of data [7]. As a result, it has been started a project of the United States government called Welsh Project, which resulted in the organization of the National Library of Medicine the way we know it today, with the participation of Eugene Garfield [5]. This author, with this activity and knowledge of previous experience, was the creator of the IF in 1955 and founder of ISI [8]. Soon after, Genetics Citation Index was published, a publication that provided the appearance in 1961, of Science Citation Index, and from it derived the Journal Impact Factor (JIF), or simply IF, aiming at creating an instrument of selection and assessment of scientific journals, as previously described [9].

The modification process of AlSi21CuNi silumin and its effect on change of mechanical properties of the alloy

The modification process of AlSi21CuNi silumin and its effect on change of mechanical properties of the alloy

Pouring temperature belongs to very important factors in obtainment of correct results of the modification. Hypereutectoid silumins are characteristic of good castability even in temperatures close to liquidus curve, what suggests implementation of low temperature of casting. However, such method of casting creates conditions to easy coarsening of primary crystals of silicon and their non-uniform distribution on microstructure of the casting. Rate of cooling of the alloy poured into mould has also an effect on results of the modification.

Table 3 shows Spearman correlation indices between serum markers of oxidative stress. There we can see that there was a statistically significant positive correlation between serum levels of thiol groups and TAC, total peroxides (LOOH) and ALB. The serum levels of thiols were also negatively correlated with the levels of TBARs and Mg. Thiol serum levels were positively correlated with TAC (r = 0.298, p < 0.001) and negatively correlated with malondialdehyde levels, an oxidant status marker (r = - 0.33, p < 0.001). The intra-assay and inter-assay coefficients of variation to novel automated thiol measurement were 3.8% and 6.7%, respectively. When manual procedure was used, the intra-assay coefficient of variation was 8.5% and the inter-assay, 10,2%. The detection limit for automated procedure was 0.05mmol/L.

THE CHALLENGE OF AUTOMATED CHANGE DETECTION: DEVELOPING A METHOD FOR THE UPDATING OF LAND PARCELS

THE CHALLENGE OF AUTOMATED CHANGE DETECTION: DEVELOPING A METHOD FOR THE UPDATING OF LAND PARCELS

In the first results, there are typically plenty of false alarms. Additional rules have been developed manually to further analyse changed objects and to reclassify some of them as field. These postprocessing rules are used to merge changed segments with their neighbouring field segments on the basis of spectral similarity. A changed segment can also be classified as field if it is spectrally similar to the entire field parcel (mean values compared). These rules help to avoid false alarms related to variation within fields. Attempts have also been made to define specific rules for objects that should be detected as changes (ditches, non-field vegetation such as trees or bushes) and objects that should be bypassed (shadows, stripe-like features in fields). The problem, however, is that while these rules correct the classification in many cases, they also produce new misclassifications. For example, some detected real changes are classified as shadows and thus lost. The results presented in this article were produced without object-specific rules, unless otherwise mentioned.

The Influence Of CSR Awareness On Consumer Purchase Decision Of A Telecommunication Network In Ghana A Case Of La Nkwantanag Madina Municipality

The Influence Of CSR Awareness On Consumer Purchase Decision Of A Telecommunication Network In Ghana A Case Of La Nkwantanag Madina Municipality

on overall company evaluations‖. Murray and Vogel (1997) have investigated the effect of associated CSR practices on consumers and presented similar findings. The CSR activities mentioned in the research are, for instance, environmental protection practices (energy conservation), engagement in acts to promote human welfare, corporate social marketing (electric safety education for schoolchildren), contribution to the economic development of the region, and consumer protection program. Their research found that CSR programs lead to improved customer attitudes towards the firm, including beliefs about the company‘s honesty, consumer responses, and increased support for the firm in labor or government disputes. Mohr et al. (2001) conducted a consumer interview project for investigating the impact of firms‘ CSR on consumer behavior. How well are consumers aware of the CSR level of individual firms? Are the purchase decisions of consumers affected by a firm‘s CSR, and how much? How do consumers think about firms‘ motivation for being socially responsible? Mohr et al. (2001) found that consumers are positive to business in general. It is not wrong to pursue economic interests. Consumers expect firms to be socially responsible. The attitudes of consumers toward socially responsible firms are more positive than toward irresponsible firms. Consumers are aware that socially responsible firms are helping themselves by practicing CSR. But this perception of consumers does not harm the positive consumer evaluations toward socially responsible firms. The study of Mohr et al. (2001) is enlightening for researchers, managers and policy makers. For managers specifically, it is clear that consumers do care about a firm‘s CSR and act accordingly. Some consumers are highly ethical in

From the introduced cross - section of casts from the probe TDAg, it results that it together with considerably grows up the depth of the contraction cavity with the growth of the temperature of casting, and what joins with this executed along its axis the volumetric contraction grows up, especially bronze B555 (Fig. 5a and 6). The bronze B10 is characterizes considerably smaller volumetric contraction (Fig. 5b and 6), however overheated 1180 °C above and cast to the hot plaster mould, in the conditions of the atmospheric pressure, it undergoes strong gassing with what considerable decrease of the depth of the contraction cavity joins (Fig. 5b 1200 ° C and Fig . 6). Zinc as high active metal in the relation of oxygen influences the lower- ing of the content of gases dissolved in the bronze B555. Consid- erably larger content Zn in the chemical composition of the bronze B555 (approx. 5%), in the comparison with the bronze B10 (to 0.5 %), it favours creation on the surface of the solidifica- tion bronze of the layer of oxides Zn and Cu, in the composition natural slags about the smaller mass density from the liquid bronze, making difficult chemical adsorption and dissolving the hydrogen and oxygen in the liquid bronze. Bronze B10 including first of all the admixture approx. 10% Sn, element of little active in the relation to oxygen, it absorbs from surroundings highly both the hydrogen as and the oxygen, what it brings in the conse- quence, together with the growth of the temperature of casting, to gassing the bronze.

The Influence of Small Amounts of Aluminium on the Spheroidization of Cast Iron with Cerium Mischmetal

The Influence of Small Amounts of Aluminium on the Spheroidization of Cast Iron with Cerium Mischmetal

The work was aimed to determine the influence of aluminium in the amount from about 0.6% to about 2.8% on the structure of cast iron treated with cerium mischmetal and subjected to graphitizing modification with 75% ferrosilicon. Four experimental melts were held during the investigation. The charge was composed of the specially prepared grey iron, containing the basic elements within the presumed limits. While determining the desirable quantity of carbon in the charge cast iron, two contradicting conditions were taken into account, i.e. that the purpose is to achieve the nodular cast iron (which means that the relatively large carbon amount would be demanded) and that introducing aluminium to the melt results in the decreased solubility of carbon in cast steel. Taking this into account, it was stated that the quantity of carbon in the charge cast iron should be maintained within the range of 3.2÷3.4%. It has been assumed that the silicon content in the charge material should fall within 0.7÷1.0%, as it was during the former investigations. Manganese content was restricted to 0.1% maximally in order to achieve the desired structure with ferrite fraction as high as possible. It has been also assumed that the content of both sulphur and phosphor should be at the possible lowest level.

Secondary publication may be acceptable for certain kinds of papers such as guidelines, articles in different languages or in commemorative journal issues. How- ever, certain requirements have to be met, including approval from the editors of both journals, prominent citation of the primary publication, obviously distinct readerships, and accurate reflection of data and inter- pretations of the primary version. The ICMJE recom- mends that a footnote on title page of the secondary version should state the primary reference such as “This article is based on a study first reported in the J. …” Sibling publications are related papers submitted to different journals with no cross citation. They are of- ten the result of a researcher dividing up the results of a study into as many papers as possible with a view to increasing publication counts - also called “salami” publication. This practice is also unethical as it frag- ments the scientific record and is unhelpful to readers. Editors can largely prevent this problem by asking authors to provide all related papers, including those in press and under review, when submitting a manu- script. Journals generally expect authors to furnish copies of any papers that overlap by more than 10% with the current submission. Editors can educate their authors that good publication practice is to provide full disclosure, full citation and full discussion of their related work. 11 It is also unacceptable to dupli-

The comparison of the structure and microhardness of the tool steel C90 and HS 6-5-2 remelted with the electric arc

Machine and tools elements made of the steel C90 and HS 6-5-2 immediately after the conventional hardening, need the tempering process. During the tempering, there is a transforma- tion of retained austenite into martensite and carbides release in martensite, what leads to the increase hardness of the high-speed steel, whereas in non-alloy steels tempering cause decrease the hardness.

PROPEC-Programa de Pós Graduação em Engenharia Cívil :: APPROACHES FOR AUTOMATED DAMAGE DETECTION IN STRUCTURAL HEALTH MONITORING

PROPEC-Programa de Pós Graduação em Engenharia Cívil :: APPROACHES FOR AUTOMATED DAMAGE DETECTION IN STRUCTURAL HEALTH MONITORING

Over the last decades, several techniques have been developed in the context of Structural Health Monitoring (SHM) programs. However, when it comes to novelty (or damage) detection, these methods are inevitably based on human decisions. Moreover, most of the strategies already published in this topic mainly focus on modal identification procedures and tracking their outputs i.e., structural modal parameters. Such approaches usually lead to high computational costs and can still be insensitive to minor changes in structural behavior, thus missing crucial damage scenarios in their initial manifestations. To circumvent these drawbacks, recent researches showed that the use of symbolic representations derived directly from raw time-domain data (e.g. acceleration measurements) could provide more damage- sensitive responses with lower computational effort. Indeed, good results have been achieved by representing raw measurements in terms of their statistical distributions over time. Nevertheless, the lack of information regarding the frequency spectrum represents a decisive drawback. Therefore, this paper presents a novel symbolic object, which considers both time and frequency responses of structural dynamic measurements. Then, the proposed methodology employs a k-medoids clustering over such objects within a moving time- window framework and uses a single-valued index to indicate whether a novelty is present in the acquired data. Two practical studies – a 3D frame tested in laboratory and a motorway bridge – show that the proposed approach provide an unsupervised and adaptive scheme for SHM applications.

Citability of original research and reviews in journals and their sponsored supplements.

Citability of original research and reviews in journals and their sponsored supplements.

The Journal of Clinical Psychiatry (JCP) was selected as the prototypical biomedical journal that regularly publishes supple- ments. JCP is a peer-reviewed psychiatry specialty journal published monthly by Physicians Postgraduate Press, Inc. [27]. JCP is the official publication of the American Society of Clinical Psychopharmacology [28] and is provided to its members as a benefit; however the only regular content that is directly attributable to activities of this society is a column, the ‘‘ASCP Corner.’’ According to JCP’s information for media planners [29], the journal has 35,613 subscribers and is the 3rd most cited psychiatric journal in the world with a journal impact factor of 5.533 as of December 2008, and ranks highest in the mean total number of office- and hospital-based issue readers of psychiatric journals according to a June 2008 FocusH Readership Study. Most subscribers receive the journal free of charge if they are designated as psychiatric clinicians in provider databases such as the American Medical Association’s Masterfile. Reprints of individual articles and supplements can also be widely distributed as part of marketing and informational campaigns conducted by the pharmaceutical industry. JCP’s masthead reads ‘‘Our primary mission is to provide lifelong learning for the physician through evidence-based, peer-reviewed scientific information about the diagnosis and treatment of behavioral health and neuropsychiatric disorders’’ [30]. Articles in the parent journal are a mixture of research reports, including reports of randomized controlled trials, and reviews. Articles in the supplements are usually reviews. Articles are indexed in MEDLINE/PubMed, EMBASE/Excerpta Medica, Psychological Abstracts, Current Contents, Science Citation Index, Hospital Literature Index, Biological Abstracts, Cumulative Index to Nursing and Allied Health Literature, International Nursing, PsycINFO, Chemical Abstracts, Adolescent Mental Health Abstracts, Alcohol and Alcohol Science Problems Database, and the Social Sciences Citation Index. Papers submitted to JCP undergo the usual and customary peer review process by expert consultants [31], i.e., typically two or more independent reviewers are charged with examining the quality of the study or review and its potential importance to the field. Supplements to JCP undergo a different review process as disclosed in the supplement, and include a planning session (telephone or live) at which the authors have the opportunity to comment on each other’s presentations/submissions, a prepubli- cation review by the pre-designated Chair of the activity for accuracy and fair balance (the Chair often writing an introduction as well as one or more articles in the supplement), and a prepublication review for fair balance by a reviewer from the CME Institute of Physicians Postgraduate Press, Inc [32]. The role of the journal editor in the production of the supplement is not explicitly stated.

REPOSITORIO INSTITUCIONAL DA UFOP: Improving author name disambiguation with user relevance feedback.

REPOSITORIO INSTITUCIONAL DA UFOP: Improving author name disambiguation with user relevance feedback.

To the best of our knowledge, in the author name disambiguation task, the only other work to explore some type of user feedback is ADANA (standing for Active Name Disambiguation) [Wang et al. 2011]. ADANA works in an interactive mode actively choosing only a few potentially erroneous disambiguated results, after a disambiguation process has been run, in order to ask the user for corrections, instead of passively waiting for user inputs. The active selection aims to minimize the number of interactions needed to maximize effectiveness. Notice that in order to obtain good results, the authors make use of a lot of additional information such as affiliation, bibliographic references, etc., that is usually not available in most cases. Differently, we here focus on the most common case when we have only the minimum amount of information in a citation (i.e., author and coauthor names, publication and venue titles). Another important differences are that ADANA can be considered as an author grouping method, while ours lies in the author assignment class of methods and that the users in ADANA are required to “correct” potentially incorrectly made decisions while we defer this decision to the end of the process and exploit the relevance feedback in some uncertain cases to help to solving the remaining ones.

Effect of Annealing Time for Quenching CuAl7Fe5Ni5W2Si2 Bronze on the Microstructure and Mechanical Properties

Effect of Annealing Time for Quenching CuAl7Fe5Ni5W2Si2 Bronze on the Microstructure and Mechanical Properties

At this scale of temperature and time (Fig. 9) it is difficult to identify the characteristic changes of the sample temperature, respectively, during the annealing (stage T2 - isothermal annealing), hyperquenching and quenching bronze (stage T3 - cooling in ambient air and T4 stage - cooling in 10% NaCl solution in water). Figure 10 shows representative characteristics of temperature changes during the isothermal annealing bronze sample at a constant temperature of t=1000 °C for 3600 s. There was a decrease of the temperature characteristic bronze samples during the annealing process in the studied range of isothermal annealing time (30, 60 and 120 min.). The presented characteristics t=f(τ) for a sample of bronze in the furnace that, after heating the furnace and the sample to a temperature of 1000 °C, there was a gradual decrease in temperature of the sample to about 996°C. Decrease of the temperature of the sample is associated with absorption of heat by the phase existing in bronze at 1000 °C, necessary for the occurrence of the following diffusion processes:

Introduction: The reticulocyte count by low cytometry (FC) – an automated counting method – can present errors due to the presence of interfering factors, contributing to a slight increase in results. However, automated methods have large advantages over the manual method, taken as reference, what justiies efforts to improve their quality. Objective: Evaluate platelet interference with the reticulocyte count by FC, using thiazole orange (TO) (FC/TO). Materials and methods: The method of reticulocyte count by FC/TO and a modiied automated equivalent method, which excluded CD61-positive cells (platelets) from analysis (FC/TO/MOD), were compared to the manual method. Conclusion: Results were analyzed according to the recommendations of the Clinical and Laboratory Standards Institute (CLSI) to assess interchangeability between the methods, by linear regression analysis and paired t-test. The exclusion of interfering fragments from result analysis by the modiied method produced results in closer proximity to those of the reference method.
