Assessing local differences between the spatio-temporal second-order structure of two point patterns occurring on the same linear network

2021

Abstract We introduce Local Indicators of Spatio-Temporal Association (LISTA) functions on linear networks and use them to build a statistical test for local second-order structure. This allows to identify differences in the spatio-temporal clustering behaviour of two point patterns, a point pattern of interest and a background one, both occurring on the same linear network. We assess the performance of the testing procedure for local second-order structure through simulation studies under a variety of scenarios that also account for different generating point processes. We show that the proposed local test is able to correctly identify the spatio-temporal difference in the local second-ord…

Synthesis and Dopamine Receptor Selectivity of the Benzyltetrahydroisoquinoline, (R)-(+)-nor-Roefractine

1998

(R)-(+)-nor-Roefractine (1) was synthesized by the Bischler-Napieralski route, using asymmetric reduction of the 1, 2-didehydro precursor imine with sodium (S)-N-CBZ-prolinyloxyborohydride. Compound 1 was able to displace [3H]-raclopride (a D2 dopamine receptor-selective ligand) from its specific binding sites in rat striatum with selectivity vs [3H]-SCH23390 (D1 dopamine receptor-selective ligand).

The subjective and objective evaluation of accomodation in Latvia in the aftercrisis period

2021

The most important wishes of people concentrate on the tendency to reach vitally significant factors (well-being, security, sustainability) that are realized through various channels – education, employment, family, material prosperity a.o.). One of the basic needs of an individual is a need for a physical shelter or a dwelling, yet, a dwelling is not only a roof over the head - it is also an indicator of the life quality. In its turn, it includes also the location of the dwelling, its technical conditions, as well as the living space – all influences the quality of life. Thereby the satisfaction with the dwelling can be linked with the satisfaction with life and well-being. On the side of …

Sustainable tourism: Measures, evidence and future prospects.

2021

The Chapter aims to provide a critical review of the quantitative approaches so far introduced in literature to measure the sustainable tourism. We focus on both variables and methods employed to obtain synthetic indicators of sustainable tourism and aim to provide some critical insights on potential new challenges caused by the current pandemic. For example, some dimensions of tourism sustainability may become more relevant in future due to the increasing attention by people on health and safety. Finally, a focus on the studies on measurement of sustainable tourism in the Mediterranean area will be provided.

The Study, From Romanian Perspective, Regarding the Reform Priorities of the Cohesion Policy

2013

This paper analyses the targets of the Romanian state according to Europe’s 200 Strategy. Being a new Member State, Romania’s targets for 2020 are lower than those of the older members. Even like this, using Eurostat indicators and the Report of World Economic Forum, my purpose is to present a comprehensive view of these differences in target levels and to explain why Romania can’t catch up with its older counter parts until 2020.

A framework for defining a sustainability rating system for railway track-beds

2017

Railways perform a significant role in the transportation system and they have relevant environmental, economic and social impacts. They are currently engineered optimizing every singular aspect rather than considering a broader system for improving the sustainability of the overall infrastructure. Thus, it is necessary to promote an effort to define a global sustainability framework for conceiving the design, construction and management of railway infrastructure. The Sustainable Rating System (SRS) proposed in this paper is a tool under development that evaluates different alternatives of railway track-bed structure. Inspired by similar efforts in the field of road engineering such as Gree…

How can we apply the models of the quality of life and the quality of life management in an economy based on knowledge?

2017

The scientific substantiations of quality have been applied to models that pertain to mathematical statistics, the probability theory, the information theory, fuzzy systems, graphic methods, time series, and algebraic and numerical methods. To these, this article aims to present a new method of applying mathematical modelling in an economy based on knowledge, by using the concept of the definite integral, the composite function, and mathematical optimisation. The research methods used in the realisation of this article are bibliographic research, creation of new models, and problem-solving. Mathematical modelling, the simulation of the quality of life, etc. are methods and techniques of bot…

Sustainable Development Model of EU Cities Compliant with UN Settings

2021

Nowadays, the globally accepted UN concept of sustainable development (SD) is gradu®ally transferred to the city level, including small and medium-sized cities. The implementation of SD settings requires regular measurement of developmental progress to monitor the level achieved in statics and dynamics, and to make strategic decisions for the next period. The existing urban SD indicator systems and indices are not well-suited for the monitoring of specific cities. Benchmarking algorithms and mathematical modelling procedures were applied to create a methodology and mathematical model for measuring the achieved urban SD level and to ensure the most objective selection and proportions of key …

An innovative model for a sustainability report in no-profit organizations

2016

After a review of the literature, the research aims to build a sustainability report for NPOs through a set of economic, environmental and social indicators based on best international practice. Then the report will be applied to a voluntary service centre (CSV) which, in terms of function and organisation, over a wide range, contains all the social and economic environmental variables to be monitored in any NPOs. The findings appear to suggest an innovative model of sustainability report for NPOs with a significant set of indicators that offer a new disclosure of the activity carried on by the organisation. The work is tested only on a limited number of NPOs which can be extended in the fu…
