Current research on statistical topics spans a wide range of ideas and fields of application. Much is connected with the systematic theory of methods for the analysis of empirical data, especially for situations, common in many areas of science and technology, where the random or haphazard element in the data is too strong to be ignored. Modern computer technology is important in enabling large amounts of data to be explored quickly and efficiently, in allowing methods involving iterative calculations to be handled as a matter of routine and in facilitating display of the results of analysis via sophisticated graphical devices. This has allowed both the development of new methods and also the application of ideas long known in principle but until relatively recently too complicated for other than occasional use. Some of the key ideas involved go back in essence to the 19th century, for example to Gauss, and others are more strongly associated with the first half of the 20th century, in particular to the pioneering work of R. A. Fisher, although many of the detailed developments are, of course, much more recent.

This article aims to describe important points in the history of panic disorder concept, as well as to highlight the importance of its diagnosis for clinical and research developments. Panic disorder has been described in several literary reports and folklore. One of the oldest examples lies in Greek mythology - the god Pan, responsible for the term panic. The first half of the 19th century witnessed the culmination of medical approach. During the second half of the 19th century came the psychological approach of anxiety. The 20th century associated panic disorder to hereditary, organic and psychological factors, dividing anxiety into simple and phobic anxious states. Therapeutic development was also observed in psychopharmacological and psychotherapeutic fields. Official classifications began to include panic disorder as a category since the third edition of the American Classification Manual (1980). Some biological theories dealing with etiology were widely discussed during the last decades of the 20th century. They were based on laboratory studies of physiological, cognitive and biochemical tests, as the false suffocation alarm theory and the fear network. Such theories were important in creating new diagnostic paradigms to modern psychiatry. That suggests the need to consider a wide range of historical variables to understand how particular features for panic disorder diagnosis have been developed and how treatment has emerged.

Mapping Information

The article addresses one of the most pressing problems for a trading enterprise, namely the problem of routing logistics flows for efficient enterprise management. To optimize itineraries, we use state-of-the-art electronic navigation and mapping systems that can be implemented in modern computer technology, from online services available on any computer to mobile devices. Navigation and mapping systems are distributed software complexes with an array of information stored in database management systems. They involve millions of static objects and huge amounts of dynamic data around the world. To optimize the logistics flows, an algorithm for an automated routing system is described. This system solves the problems of automatic calculation of the construction and recognition of the optimal route between the specified points of its beginning and the end, tracking of movement on a given route and, in the case of congested roads, redirection of logistics flows. Based on the researches and experiments on the formation of a cognitive map in the human mind and the perception of the route description, an algorithm for storing and displaying route data is considered. This algorithm takes into account the personal psychology of perception of cartographic information. Developing an algorithm for describing the routing of trading enterprise traffic flows is creating a model of automatically found path between the predetermined points of its beginning and end. This mapping information is personalized, easy to read, fast to remember, and insensitive to user errors. The proposed algorithm is universal and can be used to solve a wide range of problems of logistic flows optimization.

The 19Th Century

Levantine immigration to Chile started during the last quarter of the 19th century. This immigration, almost exclusively male at the outset, changed at the beginning of the 20th century when women started following their fathers, brothers, and husbands to the New World. Defining the role and status of the Arab woman within her community in Chile has never before been tackled in a detailed study. This article attempts to broach the subject by looking at Arabic newspapers published in Chile between 1912 and the end of the 1920s. A thematic analysis of articles dealing with the question of women or written by women, appearing in publications such as Al-Murshid, Asch-Schabibat, Al-Watan, and Oriente, will be discussed.

Abstract The article studies the existence experience of historical cities as centers of tourism development as in the case of Elabuga. The city of Elabuga is among the historical cities of Russia. The major role in the development of the city as a tourist center is played by the Elabuga State Historical-Architectural and Art Museum-Reserve. The object of the research in the article is Elabuga as a medium-size historical city. The subject of the research is the activity of the museum-reserve which contributes to the preservation and development of the historical look of Elabuga and increases its attractiveness to tourists. The tourism attractiveness of Elabuga is obtained primarily through the presence of the perfectly preserved historical center of the city with the blocks of integral buildings of the 19th century. The Elabuga State Historical-Architectural and Art Museum-Reserve, which emerged in 1989, is currently an object of historical and cultural heritage of federal importance. Museum-reserves with their significant territories and rich historical, cultural and natural heritage have unique resources for the implementation of large partnership projects. Such projects are not only aimed at attracting a wide range of tourists, but also stimulate interest in the reserve from the business elite, municipal and regional authorities. The most famous example is the Spasskaya Fair which revived in 2008 in Elabuga. It was held in the city since the second half of the 19th century, and was widely known throughout Russia. The process of the revival and successful development of the fair can be viewed as the creation of a special tourist event contributing to the formation of new and currently important tourism products.

Accounting has always been utilitarian in nature. It adapts to the changes in the business environment by meeting the need for new types of information. The change in waterborne transportation in the U.S. during the 19th century provides an example of such an environmental change that led to a need for accounting adaptation. With the advent of the steamboat, old accounting methods were modified and new ones created to meet the changes in the business environment. In the process, a standardized ships-accounting model was developed. The model can be seen in the accounting records of three ships that sailed at the beginning of the 20th century.

The revised catalogue of primatological material stored in the Museo Regionale di Scienze Naturali of Torino and in the Dipartimento di Scienze della Vita e Biologia dei Sistemi of the Università degli Studi di Torino and belonging to the historical material of the Torino University is introduced. The material, 494 specimens belonging to 399 individuals of 122 taxa, is of particular importance since specimens were mainly obtained during the 19th Century and the beginning of the 20th Century. A relevant part of the collection was created by the collaborators of the Museum, among which it is worth to mention F. De Filippi, A. Borelli and E. Festa, while other material came from purchases and donations from private people or the Royal Zoological Garden of Torino. Great part of the specimens is stuffed but also the osteological materials are of particular importance, as many of them derived from the specimens before being prepared and consisting of skulls or more or less complete skeletons. After this revision, the Lectotype and Paralectotypes of <em>Alouatta</em> <em>palliata</em> <em>aequatorialis</em> have been selected, and the type-specimen of the <em>brunnea</em> variety of <em>Cebus</em> <em>albifrons</em> <em>cuscinus</em> has been recognized. In addition, some specimens of particular historical-scientific importance have also been identified and here presented for the first time.

Basic Prerequisite

An urban residential building from the second half of the 19th century and the start of the 20th century, the so-called tenement house, is a significant representative of the architecture of the developing urban fabric in Central Europe. The vertical and horizontal load-bearing structures of these houses currently tend to show characteristic, repeated defects and failures. Their knowledge may, in many cases, facilitate and speed up the design of the historic building’s restoration without compromising its heritage value in this process. The article presents the summary of the most frequently occurring defects and failures of these buildings. The summary, however, is not an absolute one, and, in the case of major damage to the building, it still applies that, first of all, a detailed analysis of the causes and consequences of defects and failures must be made as a basic prerequisite for the reliability and long-term durability of the building’s restoration and rehabilitation. An integral part of the rehabilitation of buildings must be the elimination of the causes of the appearance of their failures and remediation of all defects impairing their structural safety, health safety and energy efficiency.

Fourth Position

AbstractThe origins of syncopation in 20th-century American popular music have been a source of controversy. I offer a new account of this historical process. I distinguish between second-position syncopation, an accent on the second quarter of a half-note or quarter-note unit, and fourth-position syncopation, an accent on the fourth quarter of such a unit. Unlike second-position syncopation, fourth-position syncopation tends to have an anticipatory character. In an earlier study I presented evidence suggesting British roots for second-position syncopation. in contrast, fourth-position syncopation – the focus of the current study – seems to have had no presence in published 19th-century vocal music, British or American. It first appears in notation in ragtime songs and piano music at the very end of the 19th century; it was also used in recordings by African-American singers before it was widely notated.

The Welfare State

AbstractThis paper attempts to trace the construction of the standard employment contract in Germany from the beginning of the 19th century onwards. In 20th century Germany, it was reinforced alongside with the consolidation of the welfare state and developed into the modern concept of the standard employment contract. Due to globalization forces and dynamics of capitalist market economies, the standard employment contract has turned into an obstacle in the way of modern economy’s progress. The future might be determined by increasing work flexibility, rising working hours, falling income and increasing unemployment rates, rendering the standard employment contract anachronistic and obsolete.

The 19Th Century

The great promises that "Statistik" yielded in the 19th century in Belgium, did  not materialise. At least as far as political statistics are concerned. In the second half of the 20th century the output was rather limited and thus very incomplete, not very professionally conceived and elaborated, disorderly provided, strongly related to an outrunned institutional approach and thus quite conservative in its orientation, veiled in inaccurate categories with the static view rather dominant. Therefore, starting from a global approach of the 3 P's (=polity, politics and policy), a rebuilding is necessary. This should provide for an inventory of existing statistical data and -above all -a masterplan to achieve a straightforward view on the 3 P's in Belgium: polity, politics and policy. A polyarchy has the right and the need to in depth information that is as complete as feasible. Statistics are very handy tools to provide this information to both policymakers and citizens.
