Self-control is a complex and multifaceted construct that can be regarded as an individual trait that follows its own developmental trajectory. In the presented study we used NAS-50 for the assessment of self-control in adolescents and young adults. Since the questionnaire has not been used before in underage participants we tested its reliability in adolescent and adult samples. We also investigated possible age and gender differences in self-control abilities as well as relations between NAS-50 and behavioral measures of cognitive control and impulsivity. Although the sample was quite small, the reliability of the questionnaire was similar to the results achieved by its authors. According to the predictions in the literature we did not find relations between NAS-50 and behavioral measures of cognitive control and impulsivity. We also did not observe significant age differences in the assessment of self-control abilities. The theoretical relevance of our results is discussed.
O b j e c t i v e s: The aim of study was to investigate the association between anxiety, depression, stress and determinants of quality of life among Iranian students. M e t h o d s: The questionnaires were completed by 275 students. The random sampling was conducted in two phases, the stratified sampling which some classes were selected among different classes of faculty of health and at the second phase, in each class the number of students who had the requirements to enter in the study were selected randomly. the logistic regression to find out the association between demographic characteristics with the quality of life was run and according to the normality status of the distribution of data the parametric or non-parametric tests were used. R e s u l t s: In the univariable model, the students that were living in their own homes had the odds of 2.18 times more than the others to have a higher quality of life level (95% CI: 1.07–4.45). In the multi variable model the anxiety and stress were significantly related to the quality of life and for increasing each 1 unit in the amount of anxiety and stress the odds of a better quality of life decreases 0.19 and 0.03 respectively. Even after adjusting for other covariates – in the multivariable model – both anxiety and stress were associated with the quality of life. C o n c l u s i o n: It is useful for the universities to understand different aspects of the students’ lives which are under the influence of stress, anxiety and depression, and also determining the resources from which they are originated.
Virtual reality (VR) technology now provides players with immersive and realistic experiences as never before. Spatial presence plays a crucial role in the introduction of immersive experience in a VR environment. Spatial presence is a special feeling of personal and physical presence in the displayed environment. In this study, we found that the first-person perspective (1PP) was more effective in raising the sense of spatial presence that induces immersive experience compared to the third-person perspective (3PP) in a VR shooting game. Moreover, eye blink rate was significantly higher in the 1PP compared with the 3PP. The 1PP game setting was more realistic than the 3PP setting, and may have raised participants’ sense of immersion and facilitated eye blink. These results indicate that eye blink rate is increased by the sense of spatial presence, and can be a good measure of subjective immersive experience in a VR environment. Neuroscientific evidences suggest that dopaminergic system is involved in such emotional experiences and physiological responses.
Cheerleading is a new sport, practiced in 110 nations; since 2016 enjoys provisional Olympic status. Its leaders claim that it is a “happy” sport, but research on its psychological effects is lacking. In this field-study we examined core-affect, positive-affect, and negative-affect in 65 cheerleaders before, during, after, and one-hour after a cheerleading training. Core-affect was more positive during and immediately after training, but it tapered off one hour following the training when feeling states were still more positive than at baseline. Negative-affect declined linearly from baseline to one-hour following training when it became significantly lower than its previous values. Positive-affect showed quadratic dynamics, in parallel with arousal, being higher during and immediately after training than during baseline, or one-hour after training. These results demonstrate for the first time that cheerleading is a “happy” sport, which apart from the skill-development also yields positive psychological emotions both during and after training.
Studies based on the most common diagnostic categories do not bring conclusive results concerning the overlapping and distinctive features of anxiety and depression, especially in the areas of attentional functioning, structure of affect, and cognitive emotion regulation. However, a new typology has been proposed which treats anxiety and depression as personality types (Fajkowska, 2013). These types – arousal and apprehension anxiety as well as valence and anhedonic depression – are constructed based on two criteria: specific structure and functions (reactive or regulative). The present paper critically examines the empirical evidence related to this approach. The data mostly confirmed the prediction that the similarities and differences in attentional and affective functioning among the anxiety and depression types would be related to their shared and specific structural and functional characteristics. The new typology turned out to be suitable for integrating the existing research findings by relating them to the structure and functions of anxiety and depression. As a result, it is useful in explaining some of the inconsistencies in literature, as it allows to identify the overlapping and distinctive features of the anxiety and depression types. It also helps to understand the mechanisms contributing to the development and maintenance of anxiety and depression, which might be useful in diagnosis and treatment. However, even though Fajkowska’s approach is an important contribution to the understanding of anxiety and depression, it is not exhaustive. Its limitations are discussed, along with proposed modifications of the theory, as well as further research directions.
Previous research reported about high comorbidity between asthma and neurodevelopmental disorders. Recently, asthma was associated also with executive functions poorness. The current study aimed to investigate the verbal and visual memory performances among fifteen asthmatic kindergarten children compared to the performances of other fifteen healthy kindergarten children. The results showed that the asthmatic group revealed poor performances in the immediate short term verbal memory and the verbal working memory tests but not in the verbal learning test as it was compared to the healthy group. In addition, the asthmatic group revealed poor performances in the visual memory tasks compared to the healthy group. The results were explained in light of the assumption that poor executive functions might be interfere the process of managing the attentional resources which are needed through the process of memory encoding and retrieval.
It is nearly impossible to study behaviour effectively without any reference to its context. This is because it is generally known in the psychological literature that behaviour is partially a product of its environment. This suggests that many behavioural processes may be universal but there are significant variations in their manifestations. For instance, love may be a universal process but its manifestation varies from one society to another. Given that ethical decision-making is a behavioural process, it stands to reason that its manifestation will vary from one culture to another. It is against this premise that this paper seeks to demonstrate that despite the existence of the ‘universal’ normative ethical principles, ethical decisions will be expected to vary across cultural space and even evolve with time. This paper achieves this objective by employing typical ethical dilemmas that Ghanaian psychologists and other health professionals encounter to show how and why what is ethical in one culture becomes unethical in the Ghanaian context and what is unethical in the Ghanaian context becomes ethical in another culture.
Semi-structured individual in-depth interviews were conducted to explore and compare which social norms with regard to the debt-incurring process are important to Poles with various experiences of indebtedness. Thematic analysis within a constructionist framework identified the social norms important in the borrowing process for Poles and revealed, as expected, a number of differences between people with various indebtedness experiences. Model borrowers have a significantly different approach to debt than unreliable debtors and non-borrowers. Model borrowers seem to be oblivious to the negative sides of loans as well as indicate fewer reasons for justifying not repaying obligations than others. For unreliable debtors, loans are a quick way to solve financial problems. They borrow money out of necessity rather than to finance any larger, long-term investments and have their own private rules for borrowing. Non-borrowers, although aware of borrowers’ higher standard of living, emphasize that debt is associated with permanent stress and psychological burden. Model borrowers, unlike the others, declare that in their immediate vicinity are only those who use and pay their loans in a timely manner.
The aim of the present study was to explore the role of temporal intelligence in English as a Foreign Language (EFL) learners’ self-regulation and self-efficacy. To this end, a general temporal intelligence (GTI-S) scale was designed based on the subconstructs of time in the literature. The scale, along with the learning self-regulation questionnaire (SRQ-L) and the English self-efficacy scale was administered to 520 EFL learners. To validate the GTI-S, confirmatory factor analysis (CFA) was run. The results of Pearson product-moment correlations demonstrated significantly positive relationships between temporal intelligence and controlled self-regulation, automatic self-regulation and self-efficacy (p<.05). Moreover, the findings of multiple regressions revealed that Linearity of Time, Economicity of Time, and Multitasking are the most important subconstructs of time with relation to these variables.
O b j e c t i v e s: Pill-takers seem to have some deficiencies in developing problem-solving styles, in which it plays an important role in their mental health. The present study has aimed to examine the role of problem-solving styles in individuals who have suicidal behavior by taking pills. M e t h o d s: This research is a case-control study in which 100 people who had attempted to commit suicide by taking pills and had gone to the toxicity emergency room of the Razi Educational and Therapeutic center in Rasht city, were compared with 100 normal people who were selected as the control group. These two groups of people were compared with each other in terms of their problem-solving styles (which is measured using Cassidy and Long problem solving styles questionnaire). R e s u l t s: After adjusting the effects of the confounding variables, i.e. level of education, marital status, residential status, history of psychiatry and alcohol addiction, it became clear that pill-takers group in comparison with the control group scores significantly higher in the non-adaptive problem-solving styles i.e. helplessness, problem-solving control, and avoidance styles (P < 0.0001) and also lower scores in adaptive styles, i.e. creative, confidence and approach styles (P < 0.0001). The interactive effects of group membership and gender were not significant in any of the problem-solving styles (P < 0.05). C o n c l u s i o n s: Problem-solving styles are regarded as important risk factors when it comes to attempting to commit suicide by taking pills. Thus, it is essential to teach problem-solving styles to at-risk patients in order to preventing suicidal behavior.
Józefa Joteyko was the outstanding scientist in the end of the 19th and in the beginning of the 20th century. Together with Maria Skłodowska-Curie she was the most famous woman and scientist of Polish origin in Europe. She was given the right to present her lectures in the Collége de France and she was, after Adam Mickiewicz, the second Polish lecturer at this great academy. She had committed her life to scientific disciplines which included child neurology, neurophysiology, psychology and pedagogy. She had managed to develop each of them evenly with the same progress and in relation to children. Such approach was aimed at understanding the child and gathering the knowledge about its character and predisposition. These was also meant to help in determining what kind of educational and professional way the child should take. The present-day psychological and pedagogic clinics are the practical fulfilment of Józefa Joteyko’s idea and we cannot imagine the contemporary education without the support of such institutions.
The aim of this study is to design a control strategy for the angular rate (speed) of a DC motor by varying the terminal voltage. This paper describes various designs for the control of direct current (DC) motors. We derive a transfer function for the system and connect it to a controller as feedback, taking the applied voltage as the system input and the angular velocity as the output. Different strategies combining proportional, integral, and derivative controllers along with phase lag compensators and lead integral compensators are investigated alongside the linear quadratic regulator. For each controller transfer function, the step response, root locus, and Bode plot are analysed to ascertain the behaviour of the system, and the results are compared to identify the optimal strategy. It is found that the linear quadratic controller provides the best overall performance in terms of steady-state error, response time, and system stability. The purpose of the study that took place was to design the most appropriate controller for the steadiness of DC motors. Throughout this study, analytical means like tuning methods, loop control, and stability criteria were adopted. The reason for this was to suffice the preconditions and obligations. Furthermore, for the sake of verifying the legitimacy of the controller results, modelling by MATLAB and Simulink was practiced on every controller.

In 1949 the first book of the Atlas of Polish Traditional Costumes series appeared. Józef Gajek was the one who initiated the series, published by Polish Folk Association to this day. He was associated with Polish Ethnographic Atlas, which had a great impact on the character of the series. Its main objective was to describe Polish traditional costumes according to particular regions. Janusz Kamocki and Barbara Bazielich were subsequent editors of the series. Since 2011 the authors of this article have been part of the editorial staff. At their initiative ten more books of the series were published in the years 2013–2018, field research on traditional handicraft was conducted and the Traditional Costume Section was established. The article describes the circumstances accompanying this editorial series appearance and discusses both main directions in research on traditional costumes and activities for popularising knowledge of this unique cultural phenomenon.
In the Accession Treaty of 16 April 2003, Poland agreed to adopt euro as its national currency, but the date of this adoption was not specified. The financial crisis in several countries of the Eurozone, in response to the world financial crisis in 2008, reduced drastically the public support in Poland for the replacement of the zloty by the euro. This article has two objectives. One is to assess the net costs, economic and political, for Poland remaining long outside the Eurozone. In this assessment the analysis includes also two official reports by National Bank of Poland, the country’s central bank, published in 2009 and 2014. The other objective is to note and assess the reforms which have been undertaken by member states of the Eurozone in response to this crisis, in order to maintain and enhance financial stability and economic effectiveness of the rules adopted at the start of the Eurozone on 1 January 1999. The author suggests to consider and adopt additional reforms. Discussed is also the USA experience with its own monetary union, and the potential influence on policy developments in the EU of increasing global competitive pressures from China and India.
Basing on Polish experience of about 5 years (since the presence of the African swine fever (ASF) in this country, starting from February 17th, 2014) and in accordance with literature the importance of the disease in wild boar is charaterised. ASF belongs to the most dangerous, very contagious diseases occurring in domestic swine and wild boar in Eurasia. In Europe, including Russia, Ukraine, Belarus, Lithuania, Latvia, Estonia, Poland, Romania, Hungary, Bulgaria, Czech Republic and Belgium ASF is existing at present and was diagnosed for short time in the frame of the Eurasian pandemy. There is a serious concern of spreading of the virus of ASF (ASFV) to other countries of Europe, not only by wild boar. However the reservoir of ASFV in this animal is playing a very important role in the maintenance of the virus and infection of pigs. Long lasting existence of ASFV in the environmnent is connected with the very high resistance to antiviral environmental factors. Following the lack of an effective immunogenic vaccine against ASF the disease can only be controlled by administrative measures. Additionally the important and recommended procedure is the significant reduction of the wild boar population. Probability of eradication of ASFV from wild boar is increased after adding quick carcass removal simultaneously by respecting biosecurity rules. If effectively implemented, fencing is more useful to delineating zones rather than adding substantially to increased efficiency of ASF control. However, segments of fencing will be particularly usefull in theses areas, where carcasses removal or intensive hunting is difficult to implement.
The consciousness of a crisis of university inclines towards its reformation. In the thinking about its revival it is necessary to take into account the archetypical idea behind university, traditions to date, contemporary conditions and visions of the future. It is also getting indispensable to take into consideration such values that ought to steer the development of university in the framework of global civilization. The tasks of university are as follows: 1) to conduct research in striving for truth in the conditions of autonomy and freedom, as well as responsibility for the present day and the future of man; 2) to educate students, which introduces them in the world of science and life, as well as teaches them to be responsible; 3) to practice public science which is present in debates undertaking to solve vital social problems. The academic community and its elites should defend the conception of university against the dictate of their political and economic counterparts who attempt to impose the idea of an entrepreneurial university which produces a utilitarian knowledge and “human principles”.
One of the main human goals is to achieve the state of happiness. Almost all people ask themselves the question of how to attain this goal. For thousands of years, philosophers and spiritual leaders and, nowadays, researchers representing various disciplines of social sciences, have been searching for the right answer to this question. One of the dilemmas intertwined in the debate about the essence of happiness relates to the tension expressed by the question “to be or to have”; the tension between the spiritual and the material world; between sacrum and profanum. Can accumulation of money and material possessions make us happy? Starting with the message passed on by a German psychoanalyst Erich Fromm in his essay “To Have or to Be” and the wisdom derived from the classic philosophical and religious works, I will attempt to define the relation between the state of happiness and the attachment to money and possessions or the attachment to social and transcendent values. This difficult, yet crucial, problem will be analyzed in the context of the current psychological knowledge related to the emotional and cognitive consequences of taking a materialistic approach to life. Erich Fromm and other thinkers who had lived hundreds of years before him, suggested that greed and pursuit of material possessions did not appease the human longing for happiness. The latest experimental research, conducted by psychologists, economists and scholars representing other disciplines of science, seem to strongly confirm these assumptions.
We discus legal status of plants obtained using NBT: whether they are to be treated as GMOs or not. The conclusion may have a negative impact on the development of research on them and their practical use. The problem of the application of provisions on GMOs in relation to the products of some of the NBT has been the subject of the decision of the Court of Justice of the European Union (CJEU) in Case C-528/16 – this topic is analyzed in details.
The aim of the article is to discuss Ingmar Bergman’s film Persona in a philosophical context and analyze the problem of the identity of the main characters. During the analysis, elements of existential thought and Sartre's philosophy were used. The psychological and philosophical layer of the film combines the common theme of broadly understood existence. The focus was on the identity problems of the main characters of the film and the linguistic layer in the context of the interpersonal conflict.
The article is an invitation to discuss the way of understanding human development as an actualization of individual’s potential. I present two opposite approaches to this particular problem: human development as choosing preferable potentials and also as striving to actualization of, in some way, every potential, especially these which concern the uniqueness of an individual. In the following parts of the article I locate the problem of human potential in three main discourses regarding: 1) human nature and its origin, 2) the possibility of full experience of individual lifespan 3) the possibility of influence through people on the content and the form of their actualizing potential. To the latter and strictly practical issue I pay most attention. I formulate five thesis regarding this issue. They may, in my opinion, be a starting point to discuss the general problem mentioned above. Therefore, they encourage to think about the mechanism of human development and the future environment of his life.
This year we are celebrating 150 anniversary of the discovery of DNA by Friedrich Miescher. His finding initiated a series of discoveries that allowed to depicts life's most famous molecule with novel features with considerable biological interest. In this article we recall the biggest mile stones of 150-year history of DNA and present the context and meaning of several key observations that have brought us closer to understanding DNA. 150 years ago, people had no idea that DNA existed, and they certainly hadn’t heard of DNA structure and sequencing. We now know that DNA is a dynamic, tortuous coil, constantly shuffling and unwinding. Today DNA is all around us, in a physical sense and in a cultural sense. It is really part of our culture. We will discuss also the little known facts, often overlooked in similar discussions. We will focus particularly on Professor Richard Altmann's from Iława, whose contribution to knowledge about nucleic acids is significant, although not well recognized so far.
The article describes problems related to intensiﬁcation of energy production at a sewage treatment plant. The authors analyze anaerobic co-digestion of sludge from a water treatment plant and sewage treatment plant. The authors proposed a methodology of the research and analyzed the preliminary results, which showed that co-digestion of sewage and water sludge enhanced biogas production. The authors hope that the results of the study will provide a basis for development of methodology for sludge control and disposal.
Multidimensional exploratory techniques, such as the Principal Component Analysis (PCA), have been used to analyze long-term changes in the ﬂow regime and quality of water of the lowland dam reservoir Turawa (south-west Poland) in the catchment of the Mała Panew river (a tributary of the Odra). The paper proves that during the period of 1998–2016 the Turawa reservoir was equalizing the river’s water ﬂow. Moreover, various physicochemical water quality indicators were analyzed at three measurement points (at the tributary’s mouth into the reservoir, in the reservoir itself and at the outﬂow from the reservoir). The water quality assessment was performed by analyzing physicochemical indicators such as water temperature, TSS, pH, dissolved oxygen, BOD5, NH4+, NO3-, NO2-, N, PO43-, P, electrolytic conductivity, DS, SO42- and Cl- . Furthermore, the correlations between all these water quality indicators were analyzed statistically at each measurement point, at the statistical signiﬁ cance level of p ≤ 0.05. PCA was used to determine the structures between these water quality variables at each measurement point. As a result, a theoretical model was obtained that describes the regularities in the relationships between the indicators. PCA has shown that biogenic indicators have the strongest inﬂuence on the water quality in the Mała Panew. Lastly, the differences between the averages of the water quality indicators of the inﬂowing and of the outﬂowing water were considered and their signiﬁcance was analyzed. PCA unveiled structure and complexity of interconnections between river ﬂow and water quality. The paper shows that such statistical methods can be valuable tools for developing suitable water management strategies for the catchment and the reservoir itself.
The essence of the methane fermentation course is the phase nature of changes taking place during the process. The biodegradation degree of sewage sludge is determined by the effectiveness of the hydrolysis phase. Excess sludge, in the form of a ﬂocculent suspension of microorganisms, subjected to the methane fermentation process show limited susceptibility to the biodegradation. Excess sludge is characterized by a signiﬁcant content of volatile suspended solids equal about 65 ÷ 75%. Promising technological solution in terms of increasing the efﬁciency of fermentation process is the application of thermal modiﬁcation of sludge with the use of dry ice. As a result of excess sludge disintegration by dry ice, denaturation of microbial cells with a mechanical support occurs. The crystallization process takes place and microorganisms of excess sludge undergo the so-called “thermal shock”. The aim of the study was to determine the effect of dry ice disintegration on the course of the methane fermentation process of the modiﬁed excess sludge. In the case of dry ice modiﬁcation reagent in a granular form with a grain diameter of 0.6 mm was used. Dry ice was mixed with excess sludge in a volume ratio of 0.15/1, 0.25/1, 0.35/1, 0.45/1, 0.55/1, 0.65/1, 0.75/1, respectively. The methane fermentation process lasting for 8 and 28 days, respectively, was carried out in mesophilic conditions at 37°C. In the ﬁrst series untreated sludge was used, and for the second and third series the following treatment parameters were applied: the dose of dry ice in a volume ratio to excess sludge equal 0.55/1, pretreatment time 12 hours. The increase of the excess sludge disintegration degree, as well as the increase of the digestion degree and biogas yield, was a conﬁrmation of the supporting operation of the applied modiﬁcation. The mixture of reactant and excess sludge in a volume ratio of 0.55/1 was considered the most favorable combination. In relation to not prepared sludge for the selected most favorable conditions of excess sludge modiﬁcation, about 2.7 and 3-fold increase of TOC and SCOD values and a 2.8-fold increase in VFAs concentration were obtained respectively. In relation to the effects of the methane fermentation of non-prepared sludge, for modiﬁed sludge, about 33 percentage increase of the sludge digestion degree and about 31 percentage increase of the biogas yield was noticed.
