Opis:
Nowadays companies concern more about how to survive and extend their own business in future in their current marketplace. However, developing and prospering a region of the country is becoming more crucial question. Successful cooperation and partnership between different sectors of economy (for instance, between companies, public and academic sectors) leads to the flourishing and prosperity of the region and consequently of a country. European Commission established smart specialization platform, which is a strategic approach to economic development of a region. By defining and developing of vision, competitive advantages and strategic preferences, region will determine knowledge-based potential. The purpose of this paper is to assign and define the collaboration/relations existed, how strong these relations are and what the expectations are between 3 sectors of economy: public, academic and business. Area of carrying out this research is Ostrobothnia region, however, connections in other regions of Finland and internationally is also presented. There have been chosen 3 industrial peaks from Ostrobothnia region: Energy, Fur and Boat industrial peaks. Analysis is conducted by implementing two core methods: Sense & Respond (S&R) and Sustainable Competitive Advantage (SCA). The goal of this research is also to use S&R method so as to allocate efficiently resources, and to define competitive priorities in cooperation. The main results show that the most tight collaboration and partnership is observed between companies and companies in all around Finland and internationally. While concerning other relationships, companies expect to have tighter cooperation especially in Ostrobothnia and other regions of Finland.

Opis:
The article presents relationship between history and management. Methodological inspirations between these disciplines have been shown and also the achievements carried out within the history of business and organizational theory have been described. The author has characterized the “historical turn” in organizational researches in the 1990s of XX century. In the subsequent part of the article, three methodological approaches have been characterized, namely: narrative research and storytelling, business history, and historical perspective in organizational research. The achievements of Polish researchers in the distinguished areas of research were taken into account. At the end, barriers to greater interest of using the historical perspective in the research of organizations, conducted by Polish researchers, have been presented. They are as follows: small share of historical knowledge in the education of management adepts, domination of a historical paradigms in organization and management research, the lack of continuity in the development of Polish organizations and scientific reflection on organizations and management in the 20th century and low historical awareness of Polish entrepreneurs and managers.

Opis:
The article considers methodological problems in the study of racist attitudes and beliefs among individuals that manifest such attitudes and beliefs and among people who experience racist behaviour. The phenomenon of racism takes different forms, but it always includes the stigmatizing traits of perceived differences in the physical appearance of a human being, leading to exclusion, discrimination and persecution. The study of racism is important because of its topicality and growing presence in various places in the world. However, the study of racism encounters serious methodological problems: firstly, related to the definition of racism, secondly, owing to the desire of respondents to be politically correct and reluctance to talk about their experiences. The situation of a researcher outsider and a researcher- insider are different, sometimes an anthropologist studying natives – both positions have advantages and disadvantages. The article concludes that the only morally transparent and efficient method for a racism researcher is the engaged study of racism.

Opis:
This research was conducted to study the adsorption of ammonium ions onto pumice as a natural and low-cost adsorbent. The physico-chemical properties of the pumice granular were characterized by X-ray diffraction (XRD), Fourier transforms infrared spectroscopy (FTIR) and scanning electron microscopy (SEM). Modeling and optimization of a NH4+ sorption process was accomplished by varying four independent parameters (pumice dosage, initial ammonium ion concentration, mixing rate and contact time) using a central composite design (CCD) under response surface methodology (RSM). The optimum conditions for maximum removal of NH4+ (70.3%) were found to be 100 g, 20 mg/l, 300 rpm and 180 min, for pumice dosage, initial NH4+ ion concentration, mixing rate and contact time. It was found that the NH4+ adsorption on the pumice granular was dependent on adsorbent dosage and initial ammonium ion concentration. NH4+ was increased due to decrease the initial concentration of NH4 and increase the contact time, mixing rate and amount of adsorbent.

Opis:
On 20th of October 2009 died Leszek Nowak, one of the most creative and original Polish philosophers. Born on 7th of January 1943, Nowak studied law (Adam Mickiewicz University, Poznań) and philosophy (Warsaw University). He lived to philosophize. It is not a conventional phrase but the true description of his activities. He devoted his live to philosophy. He got professor’s title in 1976, at the age of 33. At that time he was the youngest professor in Poland and the author of the methodological conception – the idealizational theory of science. His theory was inspired by ideas he found in Marx’s writings. He made them explicit and precise by using the language of contemporary logical philosophy. The result was the theory that offered a new, detailed and systematic picture of science [10], [18]. Leszek Nowak admired Marx’s ideas and planned to reconstruct Marx’s entire philosophical system. It soon occurred to him that Marx’s social philosophy was unable to account for the functioning of the societies of so-called real socialism. Nowak retained Marx’s materialism but rejected the narrow, economic view of society. In 1977 he started to work on a new, generalized social theory, which he called the non-Marxian historical materialism [12]. In this theory real socialism occurs as the most oppressive system in the history of the hitherto known societies. One has to be bold or naïve to work on such a theory in the country of real socialism. Leszek Nowak was aware of the risk but he did not decide to accept intellectual compromise and in 1979 disseminated the typescript of his book on real socialism. During the time of Solidarność movement he spent all energy to educate union members and to reveal the oppressive nature of socialism. He was interned on 13th of December 1981 and spent a year in jail. In 1985 he was expelled from the university and in 1989 his professorship was reinstated. Extremely hard work, engagement in the Solidarność movement, and protests during internment seriously undermined his health. In the last years Leszek Nowak was not able to teach but he painstakingly worked on his new love – metaphysics. Results of his research were published in Polish in three volumes [16], [19], [20]. In our view his conception represents a non-standard approach to metaphysical problems. In Polish philosophy Nowak’s metaphysics can be only confronted with Roman Ingarden’s The controversy over the existence of the world. It is our firm conviction that Leszek Nowak’s place in Polish philosophy in the second half of the twentieth century is defined by the following qualities: a bold search for new and original idea, laborious work to present it in a systematic way, readiness to defend it against petrifying tendencies be they scientific, political, religious or ideological.

Removal of mercury(II) (Hg(II)) from aqueous media by a new biosorbent was carried out. Natural Polyporus squamosus fungus, which according to the literature has not been used for the purpose of Hg(II) biosorption before, was utilized as a low-cost biosorbent, and the biosorption conditions were analyzed by response surface methodology (RSM). Medium parameters which were expected to affect the biosorption of Hg(II) were determined to be initial pH, initial Hg(II) concentration (Co), temperature (T (°C)), and contact time (min). All experiments were carried out in a batch system using 250 mL flasks containing 100 mL solution with a magnetic stirrer. The Hg(II) concentrations remaining in filtration solutions after biosorption were analyzed using Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES). Based on the RSM results, the optimal conditions were found to be 5.30, 47.39 mg/L, 20°C and 254.9 min for pH, Co, T (°C), and contact time, respectively. Under these optimal conditions, the maximum biosorbed amount and the biosorption yield were calculated to be 3.54 mg/g and 35.37%, respectively. This result was confirmed by experiments. This result shows that Polyporus squamosus has a specific affinity for Hg ions. Under optimal conditions, by increasing the amount of Polyporus squamosus used, it can be concluded that all Hg ions will be removed.

This paper presents the results of experimental research on heat transfer distribution under the impinging jets at high jet velocity on curved surfaces. The air jets flow out from the common pipe and impinge on a surface which is cooled by them, in this way all together create a model of external cooling system of low pressure gas turbine casing. Preliminary measurement results from the flat plate case were compared with the results from the curved surface case. Surface modification presented in this paper relied on geometry change of flat surface to the form of a ‘bump’. The special system of pivoted mirrors was implemented during the measurements to capture the heat exchange on curved surfaces of the bump. The higher values of mean heat transfer coefficient were observed for all flow cases with a bump in relation to the reference flow case with a flat plate.

The aim of the study is to assess the methodology of 2011 Population and Housing Census in terms of ethnic questions. The study focused on questions concerning national minorities and ethnic and regional dialects aside from issues of religion. Assessing census methodology legal regulations were discussed, including relation between census estimates and statutory rights of national minorities. In this topic, attention was paid to the protection of “privacy” and the confidentiality of personal data, the reliability of ethnic data obtained in censuses and the need for their acquisition. Afterwards relationship between international recommendations and the way the recognition of ethnic questions in 2011 census was presented. With regard to methodological issues, first methods of conducting population censuses were discussed. Comparing the traditional method, and the one based on administrative records, the attention was drawn to the fulfillment of the UN Recommendations as concerns basic characteristics of the census. Focused on register-based approach, the possibilities of estimating information relating to national and ethnic minorities were discussed. Attention was paid to the consequences of defining different categories of the census population and sample survey conducted within the 2011 census. Possibilities of small area statistics and calibration were presented. Particular attention was paid to the possibility of estimating information on national and ethnic minorities.

Opis:
The AISI 430 stainless steel with ferritic structure is a low cost material for replacing austenitic stainless steel because of its higher yield strength, higher ductility and also better polarisation resistance in harsh environments. The applications of AISI 430 stainless steel are limited due to insignificant ductility and some undesirable changes of magnetic properties of its weld area with different microstructures. In this research, a study has been done to explore the effects of parameters of laser welding process, namely, welding speed, laser lamping current, and pulse duration, on the coercivity of laser welded AISI 430 stainless steel. Vibrating sample magnetometery has been used used to measure the values of magnetic properties. Observation of microstructural changes and also texture analysis were implemented in order to elucidate the change mechanism of magnetic properties in the welded sections. The results indicated that the laser welded samples undergo a considerable change in magnetic properties. These changes were attributed to the significant grain growth which these grains are ideally oriented in the easiest direction of magnetization and also formation of some non-magnetic phases. The main effects of the above-mentioned factors and the interaction effects with other factors were evaluated quantitatively. The analysis considered the effect of lamping current (175-200 A), pulse duration (10-20 ms) and travel speed (2-10 mm/min) on the coercivity of laser welded samples.

Measurements of performance have always been crucial for the evaluation of telecommunication systems, especially for implementation of network control elements responsible for connection handling which regards to bandwidth reservation, modification and release. That problem also arises in the Automatically Switched Optical Network/Generalized Multiprotocol Label Switching (ASON/GMLPS) architecture, which is considered as one of the components of Next Generation Network (NGN). The European Telecommunications Standards Institute (ETSI) proposed a universal methodology of telecommunication control elements performance measurements, which can be also adopted to investigation of an ASON/GMPLS connection control layer. In this paper the application of the ETSI measurements methodology with regard to ASON/GMPLS performance is described. The implementation of a laboratory testbed as well as executed performance measurements according to the ETSI methodology and their results are presented.

This article presents selected aspects of the discussion on the cognitive status of explanatory hypotheses that were formulated at the end of the 20th century in cardiology in relation to abnormal phenomena observed in clinical practice. The aim is to provide a critical analysis of the validation process for such hypotheses. We are going to point out how their formulation contributed to the creation of three dimensions of the dispute: methodological, ontological and pragmatic. We will argue for the two theses. Firstly, due to the non-falsifiability of formulated explanatory hypotheses an instrumental attitude was adopted. Secondly, it will be demonstrated that adopted cognitive attitudes influenced the evaluation of clinical situations, and as a result, they had an impact on the decision-making process.

Opis:
The aim of this paper is to present methods of digitally synthesising the sound generated by vibroacoustic systems with distributed parameters. A general algorithm was developed to synthesise the sounds of selected musical instruments with an axisymmetrical shape and impact excitation, i.e., Tibetan bowls and bells. A coupled mechanical-acoustic field described by partial differential equations was discretized by using the Finite Element Method (FEM) implemented in the ANSYS package. The presented synthesis method is original due to the fact that the determination of the system response in the time domain to the pulse (impact) excitation is based on the numerical calculation of the convolution of the forcing function and impulse response of the system. This was calculated as an inverse Fourier transform of the system’s spectral transfer function. The synthesiser allows for obtaining a sound signal with the assumed, expected parameters by tuning the resonance frequencies which exist in the spectrum of the generated sound. This is accomplished, basing on the Design of Experiment (DOE) theory, by creating a meta-model which contains information on its response surfaces regarding the influence of the design parameters. The synthesis resulted in a sound pressure signal in selected points in space surrounding the instrument which is consistent with the signal generated by the actual instruments, and the results obtained can improve them.
