Opis:
Maritime shipping is a set of complex activities with a large number of actors involved. We focus on a subset of illegal maritime activities, such as armed robberies, maritime piracy or contraband smuggling. To fight against them and minimize their negative impact naval authorities typically introduce a number of countermeasures, such as deployed patrols or surveillance agents. Due to very high costs of countermeasures it is often beneficial to evaluate their impact using a simulation, allowing what-if analysis and evaluation of a range of scenarios before actually deploying the countermeasures. We introduce BANDIT, an agent-based computational platform, which is designed to evaluate scenarios with an accent on the modeling of different types of illegal behavior and on the interaction between agents. The platform consists of an agent behavior modeling system and a multi-agent maritime simulator. The platform allows the definition of a number of scenarios through a simple configuration and it offers the means to run these scenarios in a single or a batch mode and evaluate the results as single or aggregate data sets respectively. We demonstrate the usefulness of the platform on the scenarios of the drug smuggling problem in the seas surrounding Central America. Senario outcomes (e.g., heatmaps of activities, set of trajectories etc.) are subsequently used to help with the design of effective countermeasures, i.e., allocating naval patrols and planning their patrol routes.

Opis:
The aim of the research was to search for a family etiology of aggressive strategies for coping with a social conflict situation by adolescents, which are inherent in the aggressive model of their parents’ responses to a social conflict situation. D. Borecka-Biernat’s Questionnaire on parents’ strategies for coping with a social conflict situation (KSRwSK) and D. Borecka-Biernat’s Questionnaire on studying strategies for coping with a social conflict situation by adolescents (KSMK) were applied in our research. Empirical studies were conducted in junior high schools. They covered 893 adolescents (468 girls and 425 boys) aged 13–15 years. The analysis of the research material showed that mother and father are perceived as those who use an aggressive strategy in situations which hinder the achievement of goals and contribute to the modeling of a strategy of aggressive behavior in girls and boys, which is used by them in a social conflict situation.

Opis:
The analysis of the technogenic impact of mining on the environment was carried out. A transition to geotechnology with backfill is proposed in order to reduce the impact of mining operations. The paper presents the results of research aimed at finding the parameters of the technology for mining salt deposits with backfill and the determination of the backfilling influence on the dynamics of deformation of the undermined rock mass. The results of studies on the qualitative and quantitative assessment of the rock mass behavior (by the finite element method with the use of the FLAC3D software), extracted by the harvesters, are given. The research shows the influence of mining on the mass, changes in the maximum stresses during the cementing of the paste backfill in the stopes. It is recommended to use this approach in geotechnical assessment of the rock mass behavior in the conditions of using development systems of various classes.

Opis:
Purpose: This article deals with the problem of forming Pareto non-optimal norms of mutual behavior of investors and government in the process of decision-making related to financing designed to reduce risks in investment activity. Methodology: Considering the interdependent type (nature) of interactions between related parties, game theory tools were used to model such interactions. Much attention was directed to search for� parameters of interaction leading to certain Nash equilibriums in pure strategies. The formal results obtained with the model were verified by statistical analysis. Findings: Analysis showed that the rational behavior of related parties can lead to unexpected results. Powerful investors will aim to work in socially-oriented economies, whereas primarily small investors will operate in most liberal economies with a�minimum tax burden but with a�higher level of risk. As for governments’ behaviors, the images are the same: small economies tend to liberalize their tax systems and to secure investment faster than powerful ones. Empirical verification based on statistical data of groups of countries generally confirmed the conclusions. These formal and logical conclusions were from statistical analysis of 124 countries divided into 5 groups: OECD countries, post-socialist countries, Latin American countries, APAC countries and ACP countries. Provided that the more powerful ones are covered economies, there was stronger interdependence between the size of economies and tax burden and also between total investment and tax burden, where this dependence is positive. Originality: The results obtained used Nash equilibriums in pure strategies as models of behavioral norms to define behaviors of related parties and also to explain assumptions concerning the behaviors of investors and government.

Opis:
The aim of this article is show the concept of using of the Discrete Markov Chains to predict economic phenomena. This subject is important for two reasons. The first of them are models based on Markov chains use the statistical informations obtained during the investigation processes. Another important reason is the fact that this way of modeling is highly flexible and can be used to simulation of economic phenomenas. In this paper authors describe the idea of modeling and present the example of simply model of patient population of primary health care and show preliminary simulation results.

Opis:
Aim/purpose – The study was based on social exchange theory and addressed the effects of firm-based organizational citizenship behavior (OCB) on normative and continuance organizational commitment (OC). Multigroup behavioral differences among pharmaceutical executives were also evaluated. Design/methodology/approach – This study employed an empirical, explanatory cross-sectional study with online questionnaires administered to four hundred and one randomly selected pharmaceutical executives in Nigeria. The covariance-based structural equation modeling technique was used for testing hypotheses. Firm-based OCB domains –conscientiousness, sportsmanship, and civic virtue were regressed on OC domains of continuance, and normative. The hypothesized effects of firm-based OCB on the domains of OC were examined using Analysis of Moment Structures (AMOS). Findings – The structural model had acceptable fit measures. Conscientiousness and sportsmanship behaviors were negatively related to normative OC while civic virtue had a positive significant relationship with normative OC. Multigroup comparisons based on gender, profession, and type of organization revealed significant effects on the relations between civic virtue and normative OC. Employees highly vested with enhancing and representing their company’s image, tend to be more obligated to continue and remain with the organization. The more self-directed, and less-complaining employees are, the lower the tendency to remain with the organization. The nuances of group differences among employees had an impact on examined relationships. Research implications/limitations – Human resource managers should adequately stimulate and motivate employees to be ambassadors of the organization. This is achievable by instilling a sense of ownership and loyalty in employees. Further implications are discussed. Originality/value/contribution – The study disentangled the relations between OCB and OC in the context of pharmaceutical executives in a developing country. The study highlighted the essence of group-specific differences in behavioral evaluation among pharmaceutical executives.

Opis:
Research background: This paper integrates the marketing and corporate social responsibility concepts by investigating how the previous studies debated CSR as a business strategy. This discussion extended from academics to business practices. Hence, this study investigated the concept of CSR as a business strategy in a multifactorial fashion in the marketing field. Purpose of the article: This study evaluates the modified model of CSR initiatives as business and marketing strategy and their impact on customers' buying behavior. For this purpose, we have taken dimensions of Carroll's pyramid of CSR as marketing strategies. We have also examined the influence of brand loyalty and cause-related marketing as mediating variables and technology as a moderator between dimensions of Carroll's pyramid and customers' buying behavior. Methods: We employed modified theoretical & conceptual model for evaluating the direct and indirect hypothesized relationship. We have collected 693 responses from the structured and adapted questionnaire. The survey was done among marketing and senior managers of the Asian pharmaceutical industry. We employed SEM-based multivariate modeling to examine the hypothesized relationship. Findings & value added: The finding of this research exhibited that dimensions of Carroll's pyramid of CSR have a positive and significant impact on customers' buying behavior. The results further demonstrated that brand loyalty and cause-related marketing positively and significantly impact mediators between CSR dimensions and customers' buying behavior. Finally, the technology has a significant influence as a moderator between exogenous and endogenous factors. The undertaken study demonstrated important theoretical and practical implications. The modified conceptual framework has provided several new dimensions for future researchers to use and replicate in different economic sectors. On the other hand, practitioners of the pharmaceutical industry should incorporate Carroll's CSR pyramid as business strategies to gain the trust and respect of their customers.

Opis:
In counter-terrorism actions, commanders are confronted with difficult and important challenges. Their decision-making processes follow military instructions and must consider the humanitarian aspect of the mission. In this paper, we aim to respond to the question: What would the casualties be if governmental forces reacted in a given way with given resources? Within a similar context, decision-support systems are required due to the variety and complexity of modern attacks as well as the enormous quantity of information that must be treated in real time. The majority of mathematical models are not suitable for real-time events. Therefore, we propose an analytical model for a time-dependent prediction of terrorist attacks (ATiPreTA). The output of our model is consistent with casualty data from two important terrorist events known in Tunisia: Bardo and Sousse attacks. The sensitivity and experimental analyses show that the results are significant. Some operational insights are also discussed.

Opis:
This paper studies the solution space of systems of algebraic and difference equations, given as auto-regressive (AR) representations A(σ) β (k) = 0, where σ denotes the shift forward operator and A(σ) is a regular polynomial matrix. The solution space of such systems consists of forward and backward propagating solutions, over a finite time horizon. This solution space can be constructed from knowledge of the finite and infinite elementary divisor structure of A(σ) . This work deals with the inverse problem of constructing a family of polynomial matrices A(σ) such that the system A(σ) β (k) = 0 satisfies some given forward and backward behavior. Initially, the connection between the backward behavior of an AR representation and the forward behavior of its dual system is showcased. This result is used to construct a system satisfying a certain backward behavior. By combining this result with the method provided by Gohberg et al. (2009) for constructing a system with a forward behavior, an algorithm is proposed for computing a system satisfying the prescribed forward and backward behavior.
