Introduction. Pedestrian communications are not a single (elementary) entity; first, they are a set of elements that are interconnected, interact with each other and the external environment, have one common goal and measurable result, that is, width. Moreover, whether it is a large transport hub, a small stopping point within a land-based urban passenger transport system, or even a pedestrian path along a motor road, its space-planning solution must comply with three basic rules. They are safety, comfort and accessibility. Pedestrian communications are a set of elements whose parameters result from the proper process organization, or represent a system. The approach to the study, management, creation and development of pedestrian communications must be akin to the one applicable to a system. The purpose of the method is to develop a procedure for calcula­ting the main parameter of pedestrian communications — its total width b, in meters, and identify the conditions for a transition between various types of pedestrian communications. Materials and methods. The system approach allows to represent one complex problem as a set of simple problems that are solved faster and easier using mathematical modelling. Results. Thanks to mathematical modelling, a procedure was developed for calculating the main parameter of pedestrian communications, that is, width, with regard for low-mobility population groups in a pedestrian flow. Conclusions. Low-mobility population groups must be addressed when pedestrian communications are designed to ensure the safe and comfortable operation of transport hubs. This algorithm can also be used to analyze other directed linear pedestrian spaces.

Since the advent of modern-day screening collections in the early 2000s, various aspects of our knowledge of good handling practices have continued to evolve. Some early practices, however, continue to prevail due to the absence of defining data that would bust the myths of tradition. The lack of defining data leads to a gap between plate-based screeners, on the one hand, and compound sample handling groups, on the other, with the latter being the default party to blame when an assay goes awry. In this paper, we highlight recommended practices that ensure sample integrity and present myth busting data that can help determine the root cause of an assay gone bad. We show how a strong and collaborative relationship between screening and sample handling groups is the better state that leads to the accomplishment of the common goal of finding breakthrough medicines.

Little more than a decade after Constantine's conversion to Christianity the ancient gods and goddesses of the Graeco-Roman pantheon ceased to appear upon the official coinage and public monuments of the Empire. The personifications—Victoria, Virtus, Pax, Libertas, Securitas, etc., and the ‘geographical’ figures of Res Publica, Roma, Tellus, cities, countries, and tribes—remained. Yet some of these had, up to that very time, received, like the Olympians, their shrines and altars and other honours associated with pagan cultus; and we ask ourselves how it was that a Christian State, while rejecting the one, could retain and ‘baptize’ the other. The answer to this question, which involves the whole complex problem of the nature of pagan religious belief under the later Empire, can only be tentatively suggested here. The pantheon had eventually to go because its denizens had possessed, for the great majority of pagans, a real, objective, and independent existence.

With the growing car population in big cities, the problem of its keeping in conditions of a compact urban area has happened. The organisation of parking space in a different way has resolved this issue. Underground parking was in demand in many countries even in the XX century. By the way, they are becoming more and more popular now. The design of car parking is based on legal documents, which regulate the size of car parking seats and the width of the passage inside the garage. It is expedient to use evolutionary algorithms as one of the tools of algorithmic modelling for automation of design the car parking lots and for identifying the most effective and profitable way of the car parking space planning. So, the process of looking for the most optimal solution in underground car parking designing.

Modelling Task

In this study, we adapted the school sports day to provide opportunities to relate real-life situations with mathematical knowledge and skills. The purpose of this study was to describe the way that the teachers interact with their students and the students’ responses during mathematical modelling processes. The designing of the modelling task was inspired by the Realistic Fermi Problems about the bleacher in the school sports day. The modelling task was designed by a collaboration of mathematics teachers and educators and experimented with 10th-grade students. Each experiment lasted for 45 minutes and was conducted in the one-day camp with 45 students. The results showed that the students who had no previous experience of mathematical modelling engaged in mathematical modelling processes with their friends under the guidance and supporting of the teacher. Most of them were able to think, make assumptions, collect data, observe, make conjectures and create mathematical models to understand and solve the modelling task.

This chapter provides an overview of two different ways of working towards racial justice and regional equity. The two approaches are integration efforts on the one hand and community development efforts on the other. The tension between these two approaches is described as a conflict among groups that are generally allied on issues of social justice. It is argued that this debate is a tension within a race-conscious policy alliance, and represents a disagreement about how best to achieve the common goal of racial equity.

Within the Palaearctic taxa belonging to the genus Parus s.l. there are sympatric species at all levels of similarity. However, during the entire 20th Century no other sympatric cryptospecies were discovered, despite the progressive refinement of comparative methods. All the taxonomic changes introduced were related to determining the status of allopatric and parapatric taxa, in particular with respect to either 1. the subspecies or species status or, more rarely, 2. direct systematic relationships in the cases of Parus superciliosus, P. lugubris hyrcanus and P. davidi. This taxonomic survey of Palaearctic titmouse species aims at a synthesis of the results of both classical morphological methods on the one hand and the more recent bioacoustic and molecular studies on the other. Under the assumptions of the biospecies concept 22 Palaearctic titmouse species are distinguished, which at a higher taxonomic level belong to fourteen geospecies. Most species embrace different “population groups”, which represent the smallest bundling of taxa on a morphological-geographical basis. Within Palaearctic Paridae each of the 44 population groups presented in this paper is distinguished by a distinct morphological character set. Mean values of several morphometric measurements, such as wing length, tail length and relative tail length are provided for each population group in the species list (Section VI).

Abstract: The one of the crucial issues in the Islamic family law in Indonesia is the issue of gender equity including tug of love. It is caused by historical and empirical of Islamic family law which still put unequal status and unequal roles between men and women. That Islamic family law is law that has become the positive law or has become law and regulation in Indonesia. This article will discuss about the provision of tug of love dispute in Islamic family law in Indonesia, and the renewal of provision of tug of love dispute from a gender justice perspective. Based on the review and analysis can be concluded that the provision of tug of love dispute in Islamic family law in Indonesia (particularly Article 105 and 156 KHI) is not gender equitable and should be revised by adding the aspect of morality, aspect of health, the ability to educate and the ability to take care of children as the main parameter in determining the right parent who will possess the custody of the children.Abstrak: Salah satu persoalan krusial dalam hukum keluarga di Indonesia yang perlu mendapat pembaharuan dewasa ini adalah persoalan keadilan jender dalam hukum keluarga, termasuk hak asuh anak. Hal ini dikarenakan kenyataan historis-empiris hukum keluarga masih menempatkan status dan peran yang tidak setara antara laki-laki dan perempuan. Hukum keluarga yang dimaksud adalah hukum keluarga yang sudah menjadi hukum positif atau menjadi peraturan perundang-undangan di Indonesia. Artikel ini akan membahas tentang bagaimana ketentuan sengketa hak asuh anak dalam hukum keluarga Islam di Indonesia, serta bagaimana pembaruan ketentuan sengketa hak asuh anak dalam perspektif keadilan jender. Berdasarkan kajian artikel ini, dapat disimpulkan; Pertama, ketentuan hukum tentang sengketa hak asuh anak yang diatur dalam pasal 105 dan 156 KHI tidak responsif jender. Kedua, aspek moralitas, kesehatan dan kemampuan mendidik dan memelihara anak tidak bisa dimonopoli oleh jenis kelamin tertentu akan tetapi semua aspek tersebut sama-sama bisa dimiliki baik oleh kaum perempuan (ibu) maupun oleh kaum laki-laki (bapak).

Decrease in risk of catastrophic consequences of the geodynamic phenomena of phylum of rock bursts or earthquakes demands the development of prognosis base of these events. Research of laws of formation and development of mesocracking structures on rocks samples is the most effective path of dilating of representations about mechanisms of the geodynamic phenomena and working out of methods of reduction of risks of their catastrophic exhibitings. Mathematical modelling of mesocracking structures of various hierarchical level of geomedium demands, in turn, development of theoretical base of modelling, to transferring to calibrating models of mesomechanics. In this case, of the geomedium is represented as a thermodynamically open hierarchical-block system. Addition of such models with system of strength criteria reflecting mechanisms of shear-tension of destruction at strong compression, should become the forecasting base of preparation of the geodynamic phenomena. The methods of detection of the precursors including as precursors developed on the basis of these representations, falling into source, and to near the source areas, have multichannel character. It is defined by conditions, on the one hand, independence of such systems of precursors, and, with another one – a simultaneity and synchrony of the submitted signals serving by precursors.

The departments of political science in America's colleges and universities are now numbered in the hundreds, their students in the tens of thousands. The variety of these departments is bewildering, differing as they do in size, curriculum, teaching methods, political complexion, aspirations, and even in name. It is no easy matter to discover what the fifty-man faculty in political science at Columbia and the one-man department of government at a California junior college have in common; yet one thing in common they certainly do have: the introductory course, and the complex problem which it presents.That the introductory course does present a major problem to departments of political science everywhere was clearly acknowledged by the program committee of the 1947 meeting of the American Political Science Association, when it scheduled a panel entitled “The Beginning Course in Political Science.” The problem was further acknowledged by the panel itself; hardly a person of the many who took part in its proceedings, whether seated at the round-table or holding forth extemporaneously from the audience, failed to show some degree of candid dissatisfaction with the introductory course as presently conducted at his institution. Rare indeed is the department of political science which is willing to let its introductory course ride along through 1948 in the exact shape it assumed through 1947. The urge for improvement is nation-wide, and several prominent departments have gone so far as to relieve instructors of part of their normal teaching burden and commission them to work out definite programs of radical revision.
