Opis:
The so-called ϕ-divergence is an important characteristic describing "dissimilarity" of two probability distributions. Many traditional measures of separation used in mathematical statistics and information theory, some of which are mentioned in the note, correspond to particular choices of this divergence. An upper bound on a ϕ-divergence between two probability distributions is derived when the likelihood ratio is bounded. The usefulness of this sharp bound is illustrated by several examples of familiar ϕ-divergences. An extension of this inequality to ϕ-divergences between a finite number of probability distributions with pairwise bounded likelihood ratios is also given.

Opis:
A recent study revealed that the amount of rainfall on the Kapuas River has increased over the last 30 years. The increase in rainfall increases the possibility of high discharge events, which might lead to destructive flooding of the Kapuas River and its tributaries. Hence, the ability to characterise the pattern of high discharge events is compulsory for the development and management of the Kapuas River watershed. The main objective of this study was to assess and characterise flood patterns in the Kapuas River watershed. To achieve this objective, we utilised information and complexity measures that consisted of mean information gain (MIG), effective measure complexity (EMC) and fluctuation complexity (FC) in daily water level records from 2002 to 2011 from a gauging station in Sanggau, West Kalimantan Province. The results revealed that flood events in the Kapuas River were mainly generated by the Indo-Australian monsoon, which occurred from December to March. The anomaly in 2010, when intense flood events were observed during the dry season, can be identified as the effect of a strong negative El Niño-Southern Oscillation (ENSO). Additionally, the analysis of the information and complexity measures indicates that: (i) EMC, which reflects the length of flood events, tends to increase along with greater discharge, and (ii) MIG and FC, which denote the degree of randomness and fluctuation of flood events, respectively, tended to have higher values when the number of months without high discharge was less.

Opis:
Since 1982 the term “financial econometrics” has been present in the enormous literature that covers both methodologies and empirical analyses of the processes observed on the financial markets. The purpose of the presented paper is to indicate the milestones in financial econometrics and their usefulness and to show the contribution of the research from Poland into its development. ‘Pure’ financial econometrics methods are of special interest. The paper is directed at reviewing the recent methodologies and their applications. We focused on the contribution of Polish researchers into financial econometrics over the years, considering both the methodology and the applications. Some of the indicated publications are cited quite often, including international quotations, others are not very popular due to the language of the publication or the local reach of the journal, although many of them can be considered in line with the achievements that are presented in international empirical publications.

Opis:
Objectives: Cleaning products are considered less hazardous than those used in other sectors. Suppliers and distributors are less conscientious when it comes to informing users on health risks. The aim of the study was to elaborate on the usefulness and clarity of information in the safety data sheets (SDS) for cleaning products, and considering if the use of these SDSs can be seen as a risk factor towards occupational exposure to hazardous chemicals in the sector. Material and Methods: Safety data sheets were selected based on the risk level of the product assigned in an industrial sector scheme. 320 SDSs for cleaning products were reviewed. Constituent components found in the products over a given threshold were listed and available information thereof used to assess the perceived non-hazard consideration of the chemicals. Results: The contents of the SDSs was generic and mostly incomplete. Safety measures and health information lacked sufficient specificity despite varying compositions and concentrations of components. There is generally incompatibility between mentioned sections on the suggested non-hazardous nature of the products and health effects. Not all substances used in these products have harmonized classifications, which makes them open to various classification of the products and the suggested safety measures. This results in different companies classifying similar products differently. Risk management measures and suggested personal protective equipment (PPEs) are given haphazardly. Physical properties relevant to risk assessment are not included. Conclusions: The safety data sheets are ambiguous, and they lack relevant and important information. Inadequate information and risk assessment concerning the products can lead to workers being exposed to hazardous chemicals. Underestimation of the hazard contribution of the components of the products and the insufficient, non-objective mention of appropriate control and protective measures are the major contributing elements. There is a need to test the products in order to establish health effects and product specific safety measures.

Opis:
The article refers to the measures and methods of exerting impact on the presidential elections in France and in the USA by the Russian Federation. The Russian activity clearly indicates that elections are the target and the tool of the information warfare, in which disinformation, propaganda, lobbying, manipulation, controlled crisis and blackmail are used. Elections are perceived as a good occasion to multiply operations aiming at the destabilizing of the internal situation of individual states through the initiation of violent ethnically, socially, politically and religiously-motivated conflicts, which was presented through the Internet info-psychological operations. The internal destabilization will enable the appointment of candidates of favorable attitudes towards the Kremlin on various government positions and to undermine democratic institutions and the liberal democracy model itself.
Artykuł dotyczy środków i metod wywierania wpływu przez Federację Rosyjską na wybory prezydenckie w USA i we Francji. Rosyjska praktyka wyraźnie pokazuje, że wybory stanowią cel i narzędzie walki informacyjnej, w której stosuje się dezinformację, propagandę, lobbing, manipulację, kryzys kontrolowany i szantaż. Wybory są postrzegane jako dogodna okazja do zwiększenia oddziaływania mającego na celu destabilizację sytuacji wewnętrznej poszczególnych państw przez wywołanie gwałtownych starć na tle etnicznym, społecznym, politycznym i religijnym, co zostało ukazane na przykładzie operacji informacyjno-psychologicznych w sieci Internet. Destabilizacja wewnętrzna umożliwia wprowadzenie na urzędy kandydatów sprzyjających polityce Kremla oraz podważenie instytucji demokratycznych i samego modelu demokracji liberalnej.

The article aims the conceptualization and operationalization of the sophistication of ICT use at firm level focusing on selection of indicators and measurement methods. Due to complexity of ICT implementation and adoption process, for constructive and detailed assessment, it is necessary to get many indicators analysed. However multi-indicator approach can be unintelligible for non-professionals. Therefore, authors have decided to employ composite indicator that can be synthetic form of enterprise ICT advancement measure as well as evaluation and comparison tool.

Opis:
A discrete-time stochastic control problem for general (nonlinear in state, control, observation and noise) models is considered. The same noise can enter into the state and into the observation equations, and the state/observation does not need to be affine with respect to the noise. Under mild assumptions the joint distribution function of the state/observation processes is obtained and used for computing the Gateaux and Frechet derivatives of the cost function. Under partial observation the control actions are restricted by the measurability requirement and we compute the Lagrange multiplier associated with this "information constraint". The multiplier is called a "dual", or "shadow" price, and in the literature of the subject is interpreted as an incremental value of information . The present and the future are two factors appearing in the multiplier and we study how they are balanced as time goes on. An algorithm for computing extremal controls in the spirit of R. Rishel (1985) is also obtained.

This paper analyses how different types of technical barriers to trade (TBTs) imposed on imports of information and communications technology (ICT) goods globally affected the value and volume of imported goods during the period of 1996–2018. Key words cited in the TBTs give an indication of the aims behind the imposition of TBTs. The results indicate that TBTs have a strong positive impact on the value of imports. While many key words cited in TBTs notified to the World Trade Organization (WTO) affect the value and volume of imports in a positive way, certain other TBTs function as trade barriers.

Opis:
The military cooperation between Poland and the USA so far has undoubtedly influenced the shape of the external security. The tangible expression of this cooperation is, among others, the signing of an agreement between Poland and the USA for the purchase of the Patriot system in July 2017. As a result, Poland joined the elite group of countries possessing weapons capable of countering enemy ballistic and maneuvering missiles. It also adjusts the domestic armed forces to the NATO standards and the requirements of the modern battle-field. An additional aspect of the existing cooperation between Poland and the USA is the agreement on the protection of classified information in the military sphere. In this context, the aim of this article is to identify the scope of cooperation between Poland and the USA in the area of security measures, which should guarantee the protection of classified information considering the interests of both countries. During the considerations, two basic research methods were used: analysis and synthesis. The former method was used in relation to the content of the concluded contract and the opinions presented in the literature on the subject. The latter method was used to formulate conclusions resulting from the conducted analysis. The considerations undertaken proved that there is an area of mutual cooperation in the field of protection of classified information between Poland and the USA. They also made it possible to obtain an answer to the question of what security measures determine the effectiveness of the protection of classified information in the military sphere between the contracting states.

Abstract: The Presidential Commission of the Russian Federation to Counter Attempts to Falsify History to the Detriment of Russia’s Interests (Комиссия при президенте Российской Федерации по противодействию попыткам фальсификации истории в ущерб интересам России), established in 2009, was intended to serve as Russia’s response to similar attempts at institutionalisation in the Central and Eastern Europe region (such as the historical commissions in the Baltic states, and the Institutes of National Remembrance in Poland and Ukraine). At the same time, its activities showed a multidimensional approach, combining elements of security policy with education, culture and media, public and non-public memory policy, and formal and informal activities. Although the official emphasis was mainly on the external (foreign) determinants of the Commission’s genesis, it also became an important element of domestic policy. The Commission only operated for three years (2009–2012), but its importance as a tool of Kremlin policy cannot be overestimated. It turned difficult historical issues into “historical weapons”; introduced international public discourse to the Russian narrative, which was constructed in a spirit of confrontation with the memories of its neighbours; coordinated the activities of formal state organisations, as well as those which operated as nominally non-state bodies but were financed by the state; expanded the community of expert research which argued the Russian narrative while undermining others from abroad; and examined the options for transmitting the desired attitudes and opinions to wider audiences, creating systemic mechanisms of what has been called “counteracting the falsification of history.” The aim of this article is to show the institutional and organisational aspect of this phenomenon.
