Opis:
Protists are key components of marine microbial communities and hence of the biogeochemical mathematical models that are used to study the interaction between organisms, and the associated cycling of carbon and other nutrients. With increased computing power, models of microbial communities have markedly increased in complexity in the last 20 years, from relatively simple single nutrient currency, nutrient-phytoplankton-zooplankton-detritus (NPZD) models to plankton functional type (PFT) or trait based models of multiple organisms, or individual based models (IBMs) of specific organisms. However, our recognition, if not parameterisation, of the physiological processes that underpin both autotrophic and heterotrophic protist nutrition and growth arguably have increased faster than our modelling capability, generating a wealth of new modelling challenges. This paper therefore reviews historical development, current capability, and the future directions and challenges in protist based mathematical modelling.

Opis:
In this article we investigate the latest developments on life expectancy modeling. We review some mortality projection stochastic models and their assumptions, and assess their impact on projections of future life expectancy for selected countries in the EU. More specifically, using the age- and sex-specific data of 20 countries, we compare the point projection accuracy and bias of six principal component methods for the projection of mortality rates and life expectancy. The six methods are variants and extensions of the Lee-Carter method. Based on one-step projection errors, the Renshaw and Haberman method provides the most accurate point projections of male mortality rates and the method is the least biased. The Quadratic CBD model with the cohort effects method performs the best for female mortality. While all methods rather underestimate variability in mortality rates and life expectancy, the Renshaw and Haberman method is the most accurate.

Opis:
The analysis of the international transmission of the economic shocks and influence, among them the international effects of the national macroeconomic policies, constitutes a very wide and multi-aspectual field of the open economy macroeconomics. Flourishing interest in this field of theory and research, resulting from the post-war dynamic development of the international economic relations (in many facets of this issue) and more broadly − globalization, has led to improving the ”old” schemes and models considered as underlying the core of the open economies’ theory. The evolution of the thougts on international economic linkages and progress made in analysing them were marked by including into the analysis some new assumptions more adequate to the changes observed in the global economy and more perfectly reflecting new tendencies creating modern global ”reality”. All above has led to shaping so called new advanced approach to the open economy macroeconomics. In the empirical aspect, this approach is based on wide implementation of econometric modelling and panel data analysis. As to the theory we can say it is a synthesis – the effect of many years’ scientific research in the field. The aim of the article is to present the new advanced models of the global economy, in particular this part of them which refers to the international transmission of the effects of national macroeconomic (fiscal and monetary) policies and other shocks influencing modern open markets (interest rate shocks, price shocks, terms of trade shocks etc.). To realize so specified goal the following models will be briefly presented: International Monetary Fund’s Multimod, INTERLINK OECD (widely used in the global research in the 80s and the 90s) and the New Global Model OECD (currently implemented). As the background the chosen key steps of the evolution in the theoretical approach as well as empirical research in this stream of the open economy macroeconomics will be overally presented, starting from the Mundell-Fleming model being the crucial turning point of the thoughts on international linkages and macroeconomic policy influence. The author is going to underline the following aspects of the progress which has taken place in the questioned field of research: implementation of new approaches originating from the neo-classical concepts (e.g. the monetary approach to modelling the exchange rates), incorporating the monopolistic competition, monopolistic and oligopolistic economy models into the overall analysis, taking into consideration the short-term effects of the dynamic changes coming from temporary or permanent price, demand or terms of trade shocks, taking the assumption of the incomplete markets and intertemporal choice as an integral part of the analysis.

Opis:
Item response theory (IRT) is a model-based theory in which the responses to test items depend on some person and item characteristics, according to specific probabilistic rela-tions. The simplest and most popular are dichotomous IRT models that specify a single (i.e. unidimensional) latent trait under the assumption of normal distribution. This article reviews the latent class ordinal polytomous item response models (LC-IRT) and presents the compari-son with the well-known traditional IRT models (based on the assumption of a normally dis-tributed latent trait). The main goal of the article is to compare the estimation results of differ-ent kinds of ordinal polytomous IRT models with continuous and discrete latent variable in measuring job satisfaction in Poland. We analyzed data collected as part of the International Social Survey Programme using the ltm and MultiLCIRT packages of R.

Opis:
The goal of the paper was to verify the stability of Taylor rule parameters. The empirical analysis was performed for Poland; using 1996-2016 monthly data. More specifically, we verify two hyphotheses: (1) the behaviour of interest rate can be described using Taylor rule; (2) the Taylor rule with parameters subject to Markov switching performs better than the one with constant parameters. We take a system approach, where a Taylor rule is a part of small scale DSGE model. The bayesian inference is used to estimate the model and compare the specifications. The results indicate that models with switching parameters are better in terms of marginal data density. The best model is based on forward looking Taylor rule, where the parameters expressing the magnitude of the reaction to inflation and output gap were subject to Markov switching, while interest rate smoothing was constant. The identified regime switching can be interpreted as not responsing for inflation below the tar-get (opportunistic disinflation declared for 2001-2002 by Polish monetary authorities) or not responding to inflation driven mostly by EU accression (2004-2005) or increased VAT (2004-2005, 2011).

Opis:
Projection Pursuit Regression (PPR) was introduced by J. Friedman and W. Stuetzle in 1981. It is one of the nonparametric regression methods. The benchmark studies show very often the superiority of PPR models over other nonparametric or classical regression models in terms of the test error. PPR produces a "black-box" prediction machine and it suffers from the lack of interpretation. Thus it seems to be an important issue to find the method for evaluating the influence of the predictor variables on the response. We present the procedure that might be used to examine the strength of the influence of every predictor variable on the response variable in Projection Pursuit Regression models.

Opis:
The study examines the development of the Polish economy as well as the economies of selected European Union countries in the period from 1949 to 2006. Much space is devoted to a comparative analysis of the development economies in the countries concerned. Based on statistical data appropriate synthetic variables were set. Much space is devoted to the theory of the Johansen's method, to present the dependencies occurring in the dynamics of economic development in subsequent subperiods. The method allows for a comparative assessment of the dynamics of time series. The methods are adopted to examine the level of economic development, to determine the period of long-term equilibrium and stability.

Opis:
Today, the role of digital signatures becoming more and more significant. The signature provides authentication and integrity of a message but quite often other features like additional functionality is required from the signature. Because of that the algorithms used in ordinary signing are not sufficient, they need to be special algorithms with some additional characteristics. Undeniable signatures are a form of digital signature that have two distinctive features: the verification process is interactive (the signatures cannot be verified without signer's cooperation), a disavowal protocol allows to determine whether a given signature is a forgery. These signatures can be used, for example, to protect a software against unauthorized persons. The safety of these signatures is guaranteed by techniques of modern cryptography which is based on advanced mathematical tools and computer technology. The purpose of the article is to present selected schemes (protocols) of undeniable signatures (based on discrete log systems) such as Chaum-van Antwerpen protocol, Chaum-van Antwerpen protocol protecting against disavowal and a convertible undeniable signature protocol. Main definitions and theorems are presented and all described protocols are illustrated with examples.

Artykuł podejmuje temat stosowania modeli we współczesnej teologii. Pierwsza część rozważań dotyczy metodologicznych kwestii związanych z organizowaniem wiedzy w formie modeli. Szczególną uwagę zwrócono na podobieństwa i różnice pomiędzy teologią i innymi naukami. Druga część artykułu odnosi te rozważania o ogólniejszym charakterze do konkretnych rodzajów modeli teologicznych. Kolejno: modele trynitarne, modele soteriologiczne oraz model nupcjalny zostały scharakteryzowane z perspektywy metodologicznych wyzwań jakie ze sobą niosą. Przeprowadzona analiza pozwoliła dostrzec zarówno zalety, jak i ograniczenia stosowania tych modeli w teologii, widząc jednak ich potencjał. Ich porównanie dało także wstępną perspektywę odpowiedzi na wyzwania metodologicznej współczesnej teologii – przede wszystkim w aspekcie organizowania i wyrażania wiedzy teologicznej.
The article deals with the use of models in contemporary theology. The first part of the considerations concerns the methodological issues of organizing knowledge in the form of models. Particular attention was paid to the similarities and differences between theology and other sciences. The second part of the article relates the general considerations to specific types of theological models. In turn: models of the Trinity, soteriological models and the nuptial model have been characterized from the perspective of their methodological challenges. The conducted analysis made it possible to notice both the advantages and limitations of the use of these models in theology, seeing, however, the potential for development. Their comparison also provided an initial perspective of responding to the methodological challenges of contemporary theology - primarily in the aspect of organizing and expressing theological knowledge.

This paper contains two main parts. Section 2 defines the relationship between rules, processes, and process models (the relationship between process models and processes is clear, so we omit it). Section 3 reviews some existing research on various facets of that relationship.
