AbstractWe investigate the network topology of a comprehensive data set of the world-wide population of corporate entities. In particular, we have extracted information on the boards of all companies listed in Bloomberg’s archive of company profiles in October, 2015, a total of almost 100,000 firms. We provide information on board membership overlaps at various levels, and, in particular, show that there exists a core of directors who accumulate a large number of seats and are highly connected among themselves both at the level of national networks and at the worldwide aggregated level.

AbstractFe XIV 530.3 nm coronal emission line observations have been used for the estimation of the green solar corona rotation. A homogeneous data set, created from measurements of the world-wide coronagraphic network, has been examined with a help of correlation analysis to reveal the averaged synodic rotation period as a function of latitude and time over the epoch from 1947 to 1991.The values of the synodic rotation period obtained for this epoch for the whole range of latitudes and a latitude band ±30° are 27.52±0.12 days and 26.95±0.21 days, resp. A differential rotation of green solar corona, with local period maxima around ±60° and minimum of the rotation period at the equator, was confirmed. No clear cyclic variation of the rotation has been found for examinated epoch but some monotonic trends for some time intervals are presented.A detailed investigation of the original data and their correlation functions has shown that an existence of sufficiently reliable tracers is not evident for the whole set of examinated data. This should be taken into account in future more precise estimations of the green corona rotation period.

In recent years, major steps have been taken in terms of understanding and exploiting the vast archive of Robert Boyle (1627–91), which was presented to The Royal Society in 1769. The collection was first catalogued in the 1980s; since then, it has been extensively used in preparing the definitive editions of Boyle's Works (14 vols, 1999–2000) and Correspondence (6 vols, 2001), both published by Pickering & Chatto, and the edition of his ‘workdiaries’, which has been available online since 2001. Now, thanks to a generous grant from the Heritage Lottery Fund, various steps have been taken to enhance access to the archive—particularly by electronic means, and especially through the provision of high–quality digitized images of its key components—and thus to increase understanding of Boyle and his significance for the origins of modern science. The project, entitled ‘Robert Boyle for the twenty–first century’, is a joint initiative between Birkbeck (University of London), The Royal Society and Access to Archives. It has three main components: first, the revision of the catalogue of the Boyle archive and its presentation in online, searchable form; second, the creation of digitized images of the entire content of the core volumes of the Boyle Papers and the publication of these on the World Wide Web, some as illustrations to an updated edition of the workdiaries; and third, the provision of introductory material on Boyle aimed at schools on the Boyle website at Birkbeck.

The blockchain is a registry shared among different participants intending to eliminate the need for a central authority to maintain information. The first proposal of this technology was to eliminate financial authorities in transactions of value. However, the application of the same technique for the transaction of information could facilitate trades and offer traceability and diamond tracking around the world. The consensus is at the core of the network because it orchestrates nodes to accept new information, but it operates over a data structure in an open network, consequently leading to many complex behaviours that introduce different vulnerabilities. This work aims to highlight the vulnerability within the blockchain network based on the different participant behaviours that dominate the shared registry. Moreover, different malicious behaviour can appear on the networking layer by taking advantage of the network topology.

How do autocratic ruling parties gain power? What predicts their durability and how they fall? This article introduces the Autocratic Ruling Parties Dataset, the first comprehensive data set on the founding origins, modes of gaining and losing power, ruling tenures, and other characteristics of autocratic ruling parties. It covers all ruling parties in the world from 1940 to 2015. Contrary to common assumptions, most ruling parties are not created by sitting dictators, but follow a range of paths to power that influence their style and duration of rule. To illustrate the data’s uses, the article confirms that ruling parties stabilize autocracies. Further, parties’ origins and histories matter, with revolutionary and foreign-imposed parties the most durable and parties empowered through elections the least durable. By recognizing ruling parties’ heterogeneity, histories, and potential autonomy from individual dictators, the data can contribute to open questions on autocratic politics, regime stability, and democratization.

The popularity of the World Wide Web has led to an exponential increase of the traffic generated by its users for over a decade. Such a growth, over such a long period of time, would have saturated both the content providers and the network links had Web caching not been efficiently deployed. Web caching can improve the overall performance of the World Wide Web in several ways, depending on the decisions made regarding the deployment of the corresponding caches. By placing caches in strategic positions, the core network traffic can be reduced, the load of a content provider can be scaled down, and the quality of service, as the users perceive it, can be improved. In this article we present an overview of the major design and implementation challenges in Web caching, as well as their solutions.

Graded Readers

Extensive Reading is probably one of the hottest topics in the context of second and foreign language (L2) reading instruction (Iwahori, 2008). Krashen’s Input Hypothesis (Rodrigo, Krashen, & Gribbons, 2004) theoretically supports ER in which L2 learners’ reading development and motivation to read are nurtured by exposure to a large quantity of comprehensible and interesting input. Graded Readers (GRs), lexically and syntactically graded readers, form a core of such facilitative input in ER. In this interview, Professor Richard Day, the Founding Chair Emeritus of the world-wide leading Extensive Reading Foundation, talks about the fundamental concept of L2 reading instruction. Furthermore, he gives encouraging support and input to readers of The Language Teacher who have embarked on and want to start the practice of ER. Professor Day has been tirelessly promoting ER through L2 teacher education for many years.

This article provides a comprehensive look at the area of privatization in Poland. It provides a context and discusses the two major forces that have spurred the privatization process, as well as privatizations carried out in developing countries under the auspices of the World Bank and the IMF.The article begins with an explanation of the background to privatization in the context of state central planning, a discussion of the derivative traits of the command-and-control economy, the collapse of the system in the 1990s, the actions necessitated in society in an attempt to reform and change the system, and the reform strategies that were implement as a response to both the economic and political challenges.The article includes a discussion of the core objectives of the privatization process, the requirements of the privatization process, and an important section dealing with the actions that are necessary and complementary in preparing society and individual entities for privatization. The article concludes with an analysis of the models of privatization that were adopted in the region, along with tables delineating proceeds from privatization; the number of privatizations carried out both world-wide and in the region.

Background: Superficial fungal infections are the most common skin diseases, affecting millions of people throughout the world. Aim of the study was carried out to find, the effect of seasonal variation and socio-economic status on the prevalence of dermatophytes.Methods: A total of fifty clinically suspected cases of dermatophytosis were subjected to mycological studies.Results: Out of which 32 (64%) were culture positive Tinea corporis was the most common clinical type followed by Tinea cruris. Tricophoton rubrum 17/32 (53.12%) was the most common isolate followed by T. mentagrophytes 9/32(28.12%), T. tonsurans 3/32(9.37%), T. verrrucosum 2/32(6.25%) and T. schoenleinii 1/32(3.12%). Most of the patients belonged to the middle socio-economic group (28/50) followed by lower socio-economic group (19/50) maximum cases of dermatophytosis were reported from June to August revealing the fact that hot and humid weather during the monsoons has a great impact on the occurrence of dermatophytosis.Conclusions: It may therefore be concluded that dermatophytosis is now a days a serious public health problem in view of its high occurrence in the world wide population.
