The master architect of the Ottoman era, Architect Sinan, created and left behind a wide range of structural typologies. The most numerous of Sinan’s works were his mosques. The features defining the layout plan of Sinan’s mosques are the central domed baldachin and the characteristics of the structure on which the baldachin rests. Sinan made use of multiple support systems of sometimes four, six or eight elements in his system of dome structures, planning the layouts of his mosques around the framework of these systems. Sinan handled each of his domed and multiple pillar-supported central baldachin in different ways in terms of both the foundation of the baldachin and of the side galleries, creating in this group of structures a “Sinan style.” This paper is an attempt to make a comparative analysis of the organization of the domed central baldachin constituting the main space of the mosques of Architect Sinan, which is part of a hexagonal and octagonal baldachin system with multiple supports forming the central nucleus of the mosque, and of the side galleries, addressing the relationships between baldachin, structures, dome and galleries.

Unemployment has a wide range of adverse consequences over and above the effects of the low income which people out of work receive. In the first decades after the war Britain tended to have a lower unemployment rate than most peer countries but this changed in the 1980s and 1990s, when Britain’s unemployment rate surged during the two recessions—possibly as a result of policies designed to tackle inflation. The young, those with less education, and ethnic minorities have higher risks of unemployment and these risks are cumulative. The evidence suggests that the problems facing young men with only low qualifications became relatively worse in the 1990s and 2000s. This perhaps reflects the dark side of educational expansion, young people with low qualifications being left behind and exposed in the labour market.

PurposeOrganizational capabilities are crucial to achieve the objectives. A plethora of maturity models is available to guide organizational capabilities that create a perplexing situation about what stuff to improve and what to leave. Therefore, a unified maturity model addressing a wide range of capabilities is a necessity. This paper establishes that a flexibility maturity model is an unified model containing the operational, strategic and human capabilities.Design/methodology/approachThis paper does a comparative analysis/benchmarking studies of different maturity models/frameworks widely used in the information technology (IT) sector with respect to the flexibility maturity model to establish its comprehensiveness and application in the organization to handle multiple goals.FindingsThis study confirms that the flexibility maturity model has the crucial elements of all the maturity models. If the organizations use the flexibility maturity model, they can avoid the burden of complying with multiple ones and become objective-driven rather than compliance-driven.Research limitations/implicationsThe maturity models used in information technology sectors are used. This work will inspire other maturity models to adopt flexibility phenomena.Practical implicationsThe comparative analysis will give confidence in application of flexibility framework. The business environment and strategic options across organizations are inherently different that the flexibility maturity model well handles.Social implicationsA choice is put to an organization to see the comparison tables produced in this paper and choose the right framework according to the prevailing business situation.Originality/valueThis is the first study that makes a conclusion based on comparative benchmarking of existing maturity models.

The article considers a wide range of questions pertaining to possible and applicable harmonization of business accounting and the SNA which would, if implemented, facilitate the improvement of the information base for the compilation of national accounts and consistency of analysis of economy at micro and macro levels. The authors note that total harmonization of the two systems of information cannot be achieved due to diff erences in their key objectives. The harmonization of selected indicators and classifi cation, however, is possible and useful. In this context, the views on this matter of internationally-recognized national accounts experts, such as R. Ruggles (the USA) and F. Bos (the Netherlands), are commented on. A comparative analysis of concepts and defi nitions of some indicators of both systems is presented in the article. In particular, the diff erences between the income defi nitions. For instance, it is noted that the SNA defi nition of income is based on the concept developed by J. Hiсks and it excludes income from sales of assets and holding gains, whereas in business accounting this method is not adopted. The diff erences between two systems in defi nitions of sale of output, input, profi t and methods of valuation of indicators are also described in the article. The authors substantiate the possible directions and sequence of individual steps to the harmonization of the SNA and business accounting in the Russian Federation. They emphasize the need for close interaction between Rosstat and the Ministry of Finance of Russia in carrying out this vital work, which is necessary for creating single information, statistical and methodological space in Russia, to improve the quality of statistics and accounting, analytical work in general and management decisions.

<p>Subduction is responsible for surface displacements and deep mass redistribution. This rearrangement generates density anomalies in a wide spectrum of wavelengths which, in turn, causes important anomalies in the Earth's gravity field that are visible as lineaments parallel to the arc-trench systems. In these areas, when the traditional analysis of the deformation and stress fields is combined with the analysis of the perturbation of the gravity field and its slow time variation, new information on the background environment controlling the tectonic loading phase can be disclosed.</p><p>Here we present the results of a comparative analysis between the geodetically retrieved gravitational anomalies, based on the EIGEN-6C4 model, and those predicted by a 2D thermo-chemical mechanical modeling of the Sumatra and Mariana complexes.</p><p>The 2D model accounts for a wide range of parameters, such as the convergence velocity, the shallow dip angle, the different degrees of coupling between the facing plates. The marker in cell technique is used to compositionally differentiate the system. Phase changes in the crust and in the mantle and mantle hydration are also allowed. To be compliant with the geodetic EIGEN-6C4 gravity data, we define a model normal Earth considering the vertical density distribution at the margins of the model domain, where the masses are not perturbed by the subduction process.</p><p>Model predictions are in good agreement with data, both in terms of wavelengths and magnitude of the gravity anomalies measured in the surroundings of the Sumatra and Marina subductions. Furthermore, our modeling supports that the differences in the style of the gravity anomaly observed in the two areas are attributable to the different environments – ocean-ocean or ocean-continental subduction – that drives a significantly different dynamic in the wedge area.</p>

Identification of names of plant curatives and substances in folk and fiction texts shows close interactions between man and the world, attitudes of people towards nature. Research in phytonyms and medicinal plant names proper is most essential for the understanding of a nation’s cultural heritage. The paper examines the lexeme балтырған in Bashkir discourse. Materials. The analyzed materials include linguistic dictionaries, folklore and fiction texts of the Machine Fund of the Bashkir Language, and etymological dictionaries of Altaic languages. Goals. The study aims at a comparative investigation of the lexeme балтырған ‘hogweed’. Results. The term proves a widespread phytonym in Bashkir discourse, which is attested by that it denotes a wide range of plant species in Bashkir and has parallels in other Turkic and Mongolic languages. The lexeme is included in academic, explanatory, dialectal, phrasal, and mythological dictionaries of the Bashkir language. The comparative analysis shows that baltyrγan ‘hogweed’ usually denotes a plant of the order Apiales, a medicinal herb. Baltyrγan~ baltirγana contains the initial bal / baltïr / baldïr with the meaning ‘green, young, fresh’.

Where are the girls who made history? What evidence have they left behind? Are there places and spaces that bear witness to their memory? Girl Museum was founded in 2009 to address these questions, among many others. Established by art historian Ashley E. Remer, whose work revealed that most, if not all, museums never explicitly discuss or center girls and girlhood, Girl Museum was envisioned as a virtual space dedicated to researching, analyzing, and interpreting girl culture across time and space. Over its first ten years, we produced a wide range of art in historical and cultural exhibitions that explored conceptions of girlhood and the direct experiences of girls in the past and present. Led by an Advisory Board of scholars and entirely reliant on volunteers and donations, we grew from a small website into a complex virtual museum of exhibitions, projects, and programs that welcomes an average 50,000 visitors per year from around the world.

Cycloid reducers are gear trains which can be classified as planetary transmissions. These transmissions have a very wide range of uses in industry in transporters, robots, satellites, etc. This research presents a comparative analysis of three analytical methods for determining cycloid drive efficiency. The paper explores every mathematically formulated method and compares them to experimental results from literature. The presented methods for determining efficiency have a common property, in that they all determine losses due to friction on the bearing cam surface of the shaft, the rollers of the central gear and the output rollers. The calculation of efficiency values is done for standard power values. The methods differ primarily in the way they calculate losses. For each method of calculating efficiency there is an analysis of pros and cons. The paper concludes with suggestions as well as possible directions for further research.
