Lotka's Law and Pattern of Author Productivity in the Area of Physics Research
English

K.G. Pillai Sudhier
2013 DESIDOC Journal of Library & Information Technology  
This confirms that law does not applicable to authors of the physics literature.  ...  The productivity distribution did not fit either set of data for two different author communities when Lotka's law was applied in its original form.  ...  In other words, the Price's Square Root Law of Scientific Productivity states that, N ½ sources yield a fraction ½ of the items.  ...

Biosensors—Publication Trends and Knowledge Domain Visualization

Nasrine Olson, Juhee Bae
2019 Sensors  
An examination of trends over the years indicates that in recent years, China-based authors have been more productive in this area.  ...  While the number of publications on biosensors seems to have declined in recent years in the PubMed database, this is not the case in the Web of Science database.  ...  Conflicts of Interest: The authors declare no conflict of interest.  ...

Citation analysis for measuring the value of scientific publications: quality assessment tool or comedy of errors?

Dirk Schoonbaert, Gilbert Roelants
2007 Tropical medicine & international health  
The authors conclude that citation analysis, even when based on journal impact factors, can be a worthwhile criterion for evaluating publication records of individual scientists or research units, as long  ...  The basic concepts of citation analysis and journal impact factors are discussed in the light of quality assessment of scientific publications, individual scientists and research units.  ...  As these are not counted as source items, potential citations are 'for free', and the JIF is unfairly boosted (Dubin & Arndt 1995 ).  ...

A Robust Privacy Preserving of Multiple and Binary Attribute by Using Super Modularity with Perturbation

Priya Ranjan, Raj Kumar Paul
2018 International Journal of Scientific Research in Computer Science Engineering and Information Technology  
Those rules which contain sensitive item set with minimum threshold value are considered as sensitive. Perturbation technique is used for the hiding of sensitive rules.  ...  Experiment is done on large dataset which have all kind of attribute for implementing proposed work features. The experiments showed that the proposed algorithms perform well on large databases.  ...  The count associated with each item is incremented by one on every turn the item is meets a different transaction Tn in database Db in its scanning process.  ...

Estimating the Impact of Unknown Unknowns on Aggregate Query Results

Yeounoh Chung, Michael Lind Mortensen, Carsten Binnig, Tim Kraska
2016 Proceedings of the 2016 International Conference on Management of Data - SIGMOD '16  
The key idea is that the overlap between different data sources enables us to estimate the number and values of the missing data items.  ...  Through a series of experiments, we show that estimating the impact of unknown unknowns is invaluable to better assess the results of aggregate queries over integrated data sources.  ...  In an extreme case of having a single data item per bucket, no count or proper value estimation is possible.  ...

2015 Proceedings of the 22nd ACM SIGSAC Conference on Computer and Communications Security - CCS '15  
Due to the intricacies of this kind of scam, it is exceedingly difficult to trace, stop, and return shipments, which is why reshipping scams have become a common means for miscreants to turn stolen credit  ...  We find that there exist prolific reshipping scam operations, with one having shipped nearly 6,000 packages in just 9 months of operation, exceeding 7.3 million US dollars in yearly revenue, contributing  ...  We also thank Jamie Portell and Jonathan Todd Bame of the United States Postal Inspection Service (USPIS) for their valuable insights and the many thought-provoking discussions.  ...

A century of evolution from Harris׳s basic lot size model: Survey and research agenda

Alessandro Andriolo, Daria Battini, Robert W. Grubbström, Alessandro Persona, Fabio Sgarbossa
2014 International Journal of Production Economics  
Following Harris's work, a number of researchers have devised extensions that incorporate additional considerations.  ...  Determining the economic lot size has always represented one of the most important issues in production planning.  ...  These assume that the fraction of defective items is known and constant in each production cycle.  ...

Convenient Prices and Price Rigidity: Cross-Sectional Evidence

Edward S. Knotek

Firms may wish to set convenient prices for items that (1) are typically purchased with cash; (2) are sold alone or with a few similar items; and (3) are high-traffic transactions, i.e., require queuing  ...  I collect a new data set and find broad support for the use of convenient prices in locations where making a rapid transaction is important.  ...  Most vending machine prices are multiples of quarters. The prices of items at concession stands have similar characteristics.  ...

The political economy of sales taxes and sales tax exemptions

Thomas Stratmann
2017 Public Choice  
We find that a one-unit increase in the number of exemptions is associated with an increase between 0.10 and 0.25 percent increase in the sales tax rate. JEL-Code: D720.  ...  Abstract We analyze the choice politicians face when seeking votes from groups that lobby for sales tax rate decreases or from groups that lobby for certain tax exemptions, given the constraint that politician  ...  Second, the categories have to be broad enough to accommodate a wide variety of definitions that states may have for products or transactions.  ...
