It was believed of course that the system of combinated blood vessels which is economy would also influence countries which are doing well. However hardy none would presume that the crisis will be so deep and long-term. Nowadays there are more and more countries threatened by the crisis which seem to have no responsibility for the cause of the slowdown. There have begun new economic phenomena, which not all have the idea how to deal with. In this publication there are presented these  new unfavorable phenomena which occurred with the crisis. There is also an international comparison of Poland with other high developed countries according to recent macroeconomic changes. The comparison is the first step to find the answer if Poland is threatened by the crisis too and if we can feel safe in our country.
Speculative bubbles as anomaly of modern capital markets
Authors: Szumny Bartosz
Published: September 2015

Speculative bubbles are one of the main problems that modern economics is dealing with today. It is important problem because there is a straight relationship between bubbles and financial crises about which we hear everyday. From the 17th century “tulip bubble” to the “internet bubble” in which the prices of technological company’s shares surged and then collapsed, many investors have lost fortunes of money. What exactly causes so much panic and trouble in financial markets? In the understanding of these phenomena the behavioural finance can play an important role and consequently give us better knowledge of these phenomena. In the following paper, I have analyzed important behavioural aspects of a bubble, including: herd behaviour, information cascade, overconfidence and optimism, representativeness heuristics and conservatism bias. All these aspects will help to better understand structure of a bubble and suggest ways to mitigate the occurrences and collapses of it in financial markets.

Territorial marketing – thoughts and acts of local authorities
Authors: Knapik Anna
Published: September 2015

Territorial marketing is a marketing orientation created on the basis of other trade kinds of marketing, i.e. industrial marketing, service marketing and social marketing. The idea of territorial marketing assumes that local authorities direct their activities to specific target groups in order to satisfy their needs and ensure that they are provided with the most comfortable environment to live and run a business. Whilst creating a particular policy, local authorities take into consideration the creation of favorable living and working conditions, especially for inhabitants, investors, and tourists. It becomes more and more common that a territorial unit is perceived as a “company”, which has to be managed properly and requires right communication with its stakeholders and good relations with the media. On the basis of the analyses presented in the paper, it is assumed that territorial marketing, although it’s a relatively new marketing trend, is going to grow in importance as it enables territorial units to work and develop efficiently.
The concepts of market failure: theory and reality
Authors: Leszek Przemysław
Published: September 2015

The controversy over the economic activity of government is not a new phenomena, what is reflected in the multitude of publications associated with this issue. Despite the fact that even the substitute of consensus is still a long way, it seems that theorists have reached agreement on two issues, which – although not lead to further settlement – have an effect on the entire course and nature of the dispute. First, economists regardless of the school which they represent, they admit that market failure is a fact. Secondly, the need for intervention by the authorities within the confines of ‘wise and effective economic policy’ is justified because of necessity to correct imperfect market mechanisms. First, we focus on the view concerning market failures, and we attempt to determine the reason that certain facts – such features of the socio-economic system as the existence of externalities or imperfect information – are perceived and classified as failures. Then we demonstrate that even if the market is not functioning properly, this fact does not automatically justify intervention of government.
Industrial business cycle and the cyclical fluctuations of sold industrial output according to PAC
Authors: Kasperowicz Rafał
Published: September 2015

The first aim of the paper is to identify business cycle in the Polish industry and in departments of the industry according to PAC. The second aim is the re-examination of the co-variability between the calculated fluctuations. When identifying the fluctuations, first one has to purify the time-series of incidental and seasonal fluctuations. According to that the time-series underwent adjustment procedure of seasonal correction Census X11. This way Henderson’s curves which reflect trends and seasonal fluctuations at the same time were obtained. The next step was to state the values of trends. To establish these values the method of stochastic trend estimation, which is called Hodrick-Prescott’s filter was used. Dividing empirical values of Henderson’s curves by the implementation arising from a use of HP we get (after multiplying by 100) a series showing percentage deviations form the trend line, which means seasonal fluctuations.The plan of the paper is as follows: introduction, section 1 definition of business cycle and data, section 2 with econometric methodology, section 3 with empirical analysis, and the conclusions.

Deflation and investment activities of banks. The case of Japan in the years 1993-2008
Authors: Kozioł Waldemar
Published: September 2015

The purpose of the article is to identify determinants of investment activities of banks during deflationary process. Japanese experience suggests that the processes of long-term deflation have a substantial impact on the structure of assets and liabilities of banking institutions. In conditions of deflation and 'liquidity trap', classic, deposit-credit activities of banks do not produce adequate profits. As a result it influences negatively bank’s profitability. In this situation banks tend to look for other sources of revenue such as commissions and investment activities. Article shows causes and effects of changes in banks' balance sheets. It is also an attempt to answer the question whether there are possibilities to build an investment portfolio that help to avoid the negative effects of deflation processes.
Valuation of immovables based on an econometric models
Authors: Zbyrowski Rafał
Published: September 2015

The main purpose of this analysis is to judge the practical utility of mass-valuation methods – particularly the econometric modelling for valuation of dwellings. One of the most important part of this article is a research of value of flats in Warsaw based on a database provided by LOCUS real estate agency. The analysis have been made in three different ways. The first approach concerns the value of flats during the boom in real estate market. In this part there were verified the major factors and trends that have impact on the market value in nine Warsaw districts. Then there were showed exemplary econometric models of value of flats in Warsaw – created for sample just before the recession in real estate market. The new idea of valuation by econometric methods is to apply cross-section models. In the second part of this article database from the period of recession was analyzed. It was mentioned that statistical features of the sample had changed and the precision of the modeling had decreased. The author presents a cross-section model that would be applied for valuation of flat in current real estate market. In the third part there were presented suggestions and proposals for application of econometric models to estimate the value of flats during the recession and before. Moreover considerations have been supported by a group of practical problems connected with econometric modeling of value in real estate market.

Using the Concept of the Weighted Ishikawa Diagram for Defining the Impact of Catering Enterprises on the Environment
Authors: Malinowska Ewa
Published: September 2015

Every organization uses the various resources to achieve its aim. Among them are those that are taken from the environment, for example, energy carriers, or water. As a result of organization’s activity, some pollution is emitted to the water and atmosphere. In Poland at the moment it is seen that there is high growth rate in services in the field of institutional food that is legally obliged by polish law to implement and maintain institutional food safety system (HACCP – Hazard Analysis and Critical Control Points). The organizations that implement HACCP cause as well the environmental loads that have negative impact on environment. Concerning above mentioned issue, the article undertakes a study on the answer of the question, which environmental aspect closely connected with the maintenance of the HACCP system in an institutional food service unit, has the largest impact on the pollution of the environment. The weighted Cause and Effect Ishikawa Diagram is used as a research tool to achieve this target. Its modification that is presented in scientific literature, enables to display next to qualitative information also quantitative one. In accordance with this method “critical paths” are indicated to the most important causes that create given effect. As an effect in this article is defined – generating of environmental loads on the environment by institutional food service unit. While causes are defined as environmental aspects, characterize this organizational part of the unit that is covered by institutional food safety system. One of them is: water consumption, municipal wastes generation, energy carriers consumption: natural gas and electric energy, inorganic waste generation, cleaning supply measures consumption, the consumption of the office materials and exploitation materials to office equipment. The analysis of the quantity of particular factors that create environmental aspects show which environmental aspects have the largest impact on environment and cause its pollution. That are: water consumption, cleaning supply measures consumption and electric energy consumption.
Knowledge as a factor of development of human resources in post State Agricultural Farm areas
Authors: Wielewska Izabela
Published: September 2015

The aim of the research was to gain information on the structure of the knowledge deposit among residents of post-SAF areas. It is the level of engagement of the worker in broadening his own knowledge that frequently determines the survival of the organization on the market and its development. The research was carried out among residents of post-SAF areas in Pomorskie province, in August 2009. The method employed was diagnostic survey. Thirty questions were asked to 185 interviewees in various age. The survey included 24 merit questions and 6 personal questions. The participants of the survey were residents of 5 post-SAF villages in Pomorskie province. The majority of the interviewees were women (55,1%). The age of the interviewees – 18-60 years old. The results of the survey show that there is a high dependence between the age of the surveyed and the level of their education. Persons under 35 had much higher education than those between 36 and 60 years old. This shows an increase in the significance of possessed education. Persons with university degrees usually have a steady source of income or regular odd jobs. Those residents with a lower level of education have problems finding jobs. Some of them attend qualification courses organized by local Job Offices. They have exhausted all due unemployment benefits and finally understood that without new skills and deepening their knowledge they have serious problems finding jobs. Also, young persons admitted that it was worth attending courses and trainings, which are organized with the use of activating methods or as workshops. They allow the participants to present themselves in practice. Continuous improvement in competence and qualifications is conducive to the development of human resources in rural areas.
Financial liquidity of the horticultural enterprise PPO Siechnice in Poland
Authors: Kropsz Irena
Published: September 2015

One of the key issues in evaluating the financial condition of a company is the analysis of assets in relation to the due indebtedness, i.e. short-term obligations. Liquidity ratios calculated in such a manner help in the drawing of conclusions on the liquidity of the enterprise and its ability to pay its short-term liabilities. This paper examines the financial liquidity in 2005-2007 of a horticultural enterprise, producing and selling food, based on information available in the balance sheet, income statement, and the cash flow statement, as published in the company's financial reports. The company was selected using the following criteria: location in Lower Silesia, Poland, in a municipal-rural commune, and operating in the agricultural-food sector. The study was based on business books of the examined company. The economic analysis involved mainly the financial liquidity ratios. Additionally, descriptive and comparative methods were used to characterize and interpret the results. The results of the study show that the company had a good financial situation and had no problems with payment of current obligations without waiting for accounts receivable or de-stocking. Additionally, liquidity analysis based on transfers from its operating activity showed that the obligations of the examined company could be covered by money obtained during its operating activities.
Fertility rebound and economic growth. New evidence for 18 countries over the period 1970–2011
Authors: Dominiak Piotr , Lechman Ewa , Okonowicz Anna
Published: September 2015

Long-run impact of economic growth on fertility trends is ambiguous and sensitive for in-time variations. Noticeably, over last decades, economic growth has led to significant falls in total fertility rates in many countries. However, recently, in high-income economies a kind of ‘fertility rebound’ emerged (Goldstein, 2009; Luci and Thevenon, 2011; Day, 2012), which supports the hypothesis that reversal trends in total fertility rates are mainly attributed to economic growth. The paper unveils the relationship between total fertility rate changes and economic growth in 18 selected countries with fertility rebound observed, over the period 1970–2011, and detects the GDP-threshold at which the fertility rebound emerged. To report on the relationship we deploy longitudinal data analysis assuming non-linearity between examined variables. The data applied are exclusively derived from World Development Indicators 2013. Our main findings support the hypothesis on U-shaped relationship between the total fertility rate and economic growth in analyzed countries in 1970-2011. Along with the previous, we project the minimum level of GDP per capita (GDP-threshold) when the fertility rebound takes place.

Published: September 2015

The article focuses on regional diversity of the Polish Labor Market from institutional perspective. The Polish Labor Market is geographically diverse in terms of unemployment and employment rates, and also in terms of economic development. At the end of 2013 the difference between the lowest and the highest unemployment rate in the Polish regions was 12.1% (Wielkopolska located in the West Poland has unemployment rate of 9.6% and Warmia - Mazury in the East has unemployment of 21.7%). The question arises whether this difference comes from the structural or institutional sources. The paper describe the character of Polish Labor Market, whereas in the second part, it traces the impact of institutional variables such as real wage, Kaitz index and Gender gap on the regional unemployment rate in 2002–2012 in Poland.
The review of theories of mainstream economics on the example of economic models
Authors: Wolska Grażyna
Published: September 2015

Regardless of the fact that economics distinguishes itself from other social sciences by a high level of formal deductive modelling, it is a social science due to the essence of the economic process where a human is a subject and an object at the same time. In recent years this issue has been more frequently emphasized by economists in ongoing discussions. In the discussions, a good deal of time is devoted to economic models and, mainly, their relations with the socioeconomic reality and coherence of empirical evidence. The article presents a thesis that some mainstream economic theories have not always constituted the background to their practical applications, which led - and still can lead- to the dogmatic and inflexible use of model solutions for economic phenomena which are difficult to forecast in a non-variant rigid model. The aim is to critically analyse the beliefs about the usefulness of universal economic models in the economic reality advocated by mainstream economists, and to prove that not all economic models have constituted the background to their practical applications.

Managing commercialised media attention in complex governance networks: positive and negative effects on network performance
Authors: Klijn Erik Hans
Published: September 2015

Despite the importance of the media and the considerable literature on media logic and the mediatisation of politicians, there is very little research on effects of – as conceptualised here – commercialised media attention on network performance. To address this lacuna, the article draws on a survey of project managers involved in complex spatial projects in the four largest cities in The Netherlands (Amsterdam, Rotterdam, Utrecht and The Hague) and managers from two consultancy firms involved in similar projects (n=141). Quantitative analysis shows that perception of commercialised media attention has negative effects on network performance but that these effects are reduced considerably by network management activities.
Researching surviving cancer and sexuality using visual methods: a reflection on research rationale and negotiating ethical issues
Authors: Hammond Natalie , Cheeseman Matthew , Chantry Andrew , Peng Guo Chao Alex
Published: September 2015

This article offers an account of incorporating visual methods into a research framework inspired by graphic medicine, where comics are used in patient care. We conducted interviews, focused on sexual wellbeing, with 12 leukaemia survivors. The findings from these interviews were transformed into visual representations. We outline how our study was guided by feminist research principles and reflect on the tension between the flexibility that visual methods require and the rigidity of National Health Service ethical regulations
Do espiritococus à fábrica de loucos: o espiritismo sob a retórica da aniquilação na imprensa católica cearense
Authors: Silva Marcos José Diniz
Published: September 2015

O artigo se propõe a analisar os embates religiosos entre católicos e espíritas no Ceará das primeiras décadas do século XX, a partir dos discursos veiculados pela imprensa católica local, tomando como referencial teórico central a proposta de existência de uma “retórica da aniquilação”, inspirada por sua vez nos estudos sociológicos da “estratégia da aniquilação”, próprios de ambientes competitivos e conflituosos, onde instâncias dominantes, detentoras de poder de definição, voltam-se contra as ameaças às definições sociais estabelecidas, atribuindo-lhes definições com status ontológicos e cognoscitivos desqualificadores.

História das Ideias: abordagens sobre um domínio historiográfico.
Authors: Silva Ricardo Oliveira da
Published: September 2015

O artigo apresenta uma breve visão panorâmica sobre o debate epistêmico ocorrido no domínio historiográfico conhecido como História das Ideias ao longo do século XX. Para isto destacamos a proposta das “ideias-unidade” de Arthur Lovejoy, o “contextualismo linguístico” de Quentin Skinner e a “abordagem dialógica” de Dominick LaCapra. Cada uma destas abordagens contribuiu para enriquecer a reflexão teórica e metodológica e tornar a História das Ideias uma área de conhecimento profícua para o desenvolvimento da pesquisa histórica.
Prematuridade dos recém-nascidos em Porto Alegre e seus fatores associados.
Authors: Silva Talu Haubert da , Fensterseifer Lísia Maria
Published: September 2015

Este estudo tem o objetivo de encontrar os fatores associados à prematuridade nos nascidos vivos em Porto Alegre, no ano de 2008, e estimar a prevalência da prematuridade nos anos de 2001 a 2008. Trata-se de um estudo transversal utilizando os dados do SINASC (Sistema de Informações sobre Nascidos Vivos) de Porto Alegre. Foram realizados os testes qui-quadrado e de tendência linear de Wald entre a variável dependente (prematuridade) e as independentes. Para verificar a associação dos fatores estudados à prematuridade, realizou-se a análise de regressão de Poisson. Verificou-se que a prematuridade, em Porto Alegre, vem aumentando e, em 2008, foi de 9,9%. O risco de nascimento prematuro aumentou, em proporção inversa à do número de consultas de pré-natal (quanto menos consultas, maior o risco da prematuridade), e em mães com idade superior a 40 anos e naquelas submetidas ao parto cesáreo. Assim é possível indicar que o incentivo ao pré-natal e o desestímulo ao parto cesariano eletivo podem diminuir a prematuridade. Ainda é importante realizar mais pesquisas utilizando os bancos de dados disponíveis para indicar suas limitações e melhorar a qualidade dessas informações.
Finding Pareto optimal groups
Authors: Liu Jinfei , Xiong Li , Pei Jian , Luo Jun , Zhang Haoyu
Published: September 2015

Skyline computation, aiming at identifying a set of skyline points that are not dominated by any other point, is particularly useful for multi-criteria data analysis and decision making. Traditional skyline computation, however, is inadequate to answer queries that need to analyze not only
individual
points but also
groups
of points. To address this gap, we generalize the original skyline definition to the novel group-based skyline (G-Skyline), which represents Pareto optimal groups that are not dominated by other groups. In order to compute G-Skyline groups consisting of
k
points efficiently, we present a novel structure that represents the points in a directed skyline graph and captures the dominance relationships among the points based on the first
k
skyline layers. We propose efficient algorithms to compute the first
k
skyline layers. We then present two heuristic algorithms to efficiently compute the G-Skyline groups: the point-wise algorithm and the unit group-wise algorithm, using various pruning strategies. The experimental results on the real NBA dataset and the synthetic datasets show that G-Skyline is interesting and useful, and our algorithms are efficient and scalable.

MapReduce and Spark are two very popular open source cluster computing frameworks for large scale data analytics. These frameworks hide the complexity of task parallelism and fault-tolerance, by exposing a simple programming API to users. In this paper, we evaluate the major architectural components in MapReduce and Spark frameworks including: shuffle, execution model, and caching, by using a set of important analytic workloads. To conduct a detailed analysis, we developed two profiling tools: (1) We correlate the task execution plan with the resource utilization for both MapReduce and Spark, and visually present this correlation; (2) We provide a break-down of the task execution time for in-depth analysis. Through detailed experiments, we quantify the performance differences between MapReduce and Spark. Furthermore, we attribute these performance differences to different components which are architected differently in the two frameworks. We further expose the source of these performance differences by using a set of micro-benchmark experiments. Overall, our experiments show that Spark is about 2.5x, 5x, and 5x faster than MapReduce, for Word Count, k-means, and PageRank, respectively. The main causes of these speedups are the efficiency of the hash-based aggregation component for combine, as well as reduced CPU and disk overheads due to RDD caching in Spark. An exception to this is the Sort workload, for which MapReduce is 2x faster than Spark. We show that MapReduce's execution model is more efficient for shuffling data than Spark, thus making Sort run faster on MapReduce.
Towards maximum independent sets on massive graphs

Maximum independent set (MIS) is a fundamental problem in graph theory and it has important applications in many areas such as social network analysis, graphical information systems and coding theory. The problem is NP-hard, and there has been numerous studies on its approximate solutions. While successful to a certain degree, the existing methods require memory space at least linear in the size of the input graph. This has become a serious concern in view of the massive volume of today's fast-growing graphs.

In this paper, we study the MIS problem under the
semi-external
setting, which assumes that the main memory can accommodate all vertices of the graph but not all edges. We present a greedy algorithm and a general
vertex-swap
framework, which swaps vertices to incrementally increase the size of independent sets. Our solutions require only few sequential scans of graphs on the disk file, thus enabling in-memory computation without costly random disk accesses. Experiments on large-scale datasets show that our solutions are able to compute a large independent set for a massive graph with 59 million vertices and 151 million edges using a commodity machine, with a memory cost of 469MB and a time cost of three minutes, while yielding an approximation ratio that is around 99% of the theoretical optimum.
