A study is conducted to examine the costs, benefits and strategic value of the redistribution function in the industrial paper and plastics industry. Specifically, the study seeks to find out what the value-added of the redistribution channel is, how distributors should source their products, how manufacturing companies can use their channel management policies to boost their profits, and how inventory and stock control policies impact the aforementioned issues. Results offer an economic justification for the role of redistributor in the industrial paper and plastics industry. The existence of middlemen in the distribution system is found to be advantageous for all players in the industry. They boost the inventory turns of distributors and allow manufacturers to cater to small distributors. Without redistributors, the costs of distributors would soar.

This article from New Scientist discusses how mathematics can be used to wrap gifts in a precise and efficient manner. The author explains that when wrapping box-shaped gifts, measuring the length and thickness of the box can help determine the amount of paper needed. For cylindrical gifts, the paper should be slightly wider than the diameter of the gift and the length should be the sum of the diameter and the length of the gift. The article also provides instructions for wrapping equilateral triangular prism gifts and large, flat, square-ish gifts using mathematical methods. The author emphasizes the importance of aligning the pattern on the paper for maximum aesthetic appeal. [Extracted from the article]

The question is asked: If a paper has not been cited by time t after its publication, what is the probability that it will ever be cited? A stochastic model for describing the citation process in the presence of obsolescence is used to discover an answer.

Literature in cognitive psychology is used to analyze the thought processes behind the development of linear programming (LP) models. Emphasis is on understanding how the authors organize problems and models in their work. A kind of cognitive history of the early years of LP model building is thus drawn. Three hypotheses are investigated, namely, an organization of problems into categories by kinds of transformations, organization by model type and organization of problems and models by industry. Analysis of historical processes confirms that there is transfer and an underlying organization and that there are multiple dimensions forming relationships among problems and models. The three hypotheses forwarded are confirmed to varying degrees.

Seven process categories of research strategies used by operations research (OR) and management science (MS) workers are identified. These strategies are ripple, embedding, bridging, structuring, creative application, statistical modeling and transfer of technology. A sample of articles appearing in the 1992 issues of the flagship journals Operations Research, Management Science and Interfaces is analyzed to determine which of the aforementioned strategies are commonly used by OR/MS researchers. The study also aims to link these research methodologies to the types of research work found at the extremes of Reisman and Kirschnick's (1994) six-point scale for categorizing OR/MS work. The results show that the ripple process is most often applied in theoretical research, while the transfer-of-technology process is most used in true applications.

Some operations research (OR) practitioners have complained about the field's 'devolution' or 'regression.' In the past, the science was market-oriented in that researchers sought solution to real-world problems. However, current OR is input-oriented in that mathematicians search for problems that fit their models. A detailed survey of OR and management science publications is conducted to ascertain the existence of this trend. In particular, the amount of space allocated to theory relative to applications is analyzed for such flagship journals as Operations Research, Management Science and Interfaces, using a five-point classification scale. Comparison of the 1962 and 1992 editions of the first two journals, and the 1972 and 1992 editions of the last, reveal that usage of the terms 'application' and 'data' differ in degree and kind, respectively. The results suggest that OR practitioners need to reassess the profession and chart its future course.

A controversial mathematical proof known as the ABC conjecture has sparked bitter divisions among mathematicians. In 2012, Shinichi Mochizuki published a 500-page proof of the conjecture, but many found it incomprehensible. Kirti Joshi at the University of Arizona has now proposed a proof that he claims fixes the problems with Mochizuki's work, but Mochizuki and his supporters remain unconvinced. The debate centers around a part of Mochizuki's proof called Conjecture 3.12, which Joshi believes he has addressed more satisfactorily. However, the paper has not been peer-reviewed, and the controversy continues. [Extracted from the article]

A large-scale empirical analysis of journals from every field in Thomson Reuters' Web of Science database is performed to evaluative bibliometrics which is the characterization of the citation distribution of papers in the scientific literature. The results strongly suggested that the discrete lognormal distribution is a globally accurate model for the distribution of 'eventual impact' of scientific papers published in single-discipline journal in a single year that is removed sufficiently from the present date.

The science and technology activities in China are rapidly growing since 90s. This paper analyzes the production of scientific papers and the factor of increasing papers, and Japan-China relationship in co-authored papers. The growth rate of papers production became the sixth place in the world, the world share of papers increased by more than three times, and the papers production has concentrated on priority universities since the implementation of the top priority policy (211 project). And in internationally co-authored papers, Japan-China relationship rapidly deepens in the high share fields such as chemistries, materials, physics and engineering, while in mathematics in which China exceeds Japan, Japan-China relationship is not strong.
