Opis:
The article addresses aspects of time in the context of selected aspects of Christian spiritual life. Spirituality is associated with an identification and formation of attitudes, therefore the article is an analysis of some elements of a proper Christian attitude towards time. The first element is a Christian understanding of time as both chronos and kairos. The second dimension of a Christian attitude, defined by the biblical words ‘sleep’ and ‘watch’, relates to watchfulness or vigilance as the best form of spending one’s time. The third aspect of a Christian attitude is based on the three dimensions of time – past, present and future –   in relation to Christian spiritual life. The last part of the article is devoted to perseverance, which is the greatest challenge given to every Christian during the time allotted to them on earth. In the conclusion, the Christian experience of time shows its originality and theologically rooted wisdom.

Opis:
Recently, the persistence-based decomposition (PBD) model has been introduced to the scientific community by Rende et al. (2019). It decomposes a spread time series between two securities into three components capturing infinite, finite, and no shock persistence. The authors provide empirical evidence that the model adopts well to noisy high-frequency data in terms of model fitting and prediction. We put the PBD model to test on a large-scale high-frequency pairs trading application, using S&P 500 minute-by-minute data from 1998 to 2016. After accounting for execution limitations (waiting rule, volume constraints, and short-selling fees) the PBD model yields statistically significant and economically meaningful annual returns after transaction costs of 9.16 percent. These returns can only partially be explained by the exposure to common risk. In addition, the model is superior in terms of risk-return metrics. The model performs very well in bear markets. We quantify the impact of execution limitations on risk and return measures by relaxing backtesting restrictions step-by-step. If no restrictions are imposed, we find annual returns after costs of 138.6 percent.

Opis:
Digital games have long been investigated for links to negative influences, but they exert a range of impacts on players. A variety of factors can contribute to stressful experiences in play, including game content, player interactions, and gender. This project uses qualitative methods to better understand how players experience and perceive these stressors and why they persist despite them. There are a surprising number of ways that players’ experiences align in spite of gender. Players encounter stress with both design and social experiences, are inclined to “rage quit” if stressors are substantial enough, and are increasingly averse to toxic communities. However, there are also gender-specific experiences. Men are much more concerned with the skillsets of other players, while women worry about their own performance. Further, these experiences of stress complicate our understandings of distress and eustress, with players less motivated by stressors than they are by the anticipated future relief from distress.

Opis:
This paper refers to the historical experience of Poland in order to demonstrate the importance of former institutions on present regional differences in the norms regarding education. Previous studies revealed significant discrepancies between the scholastic achievements of students in different regions in Poland, ones that correspond to the partition of the country by its three neighbours (Austria, Prussia, and Russia), lasting from the late 18th century to the close of WWI. In particular, students in the former Austrian partition perform better than their peers in the two other regions. In this study, a self-designed survey of parents is used to operationalize different kinds of norms regarding education. As it turns out, parents from the region formerly under Austrian rule show more trust in educational institutions, more belief in the formative role of schooling, and less conviction in the material returns from education. The results show that contemporary discussions on the geography of educational achievements need to take into account the broad cultural context of education.

Opis:
The persistence of atrazine residues in soils may have an effect on the contamination of the ground water or surface water. Besides the active ingredients, pesticide formulations contain many other compounds called adjuvants. One of them is the Atpolan 80 EC which belongs to the group of oil mineral adjuvants used as lank-mix. The utilization of a fraction of paraffin oil 1113 is one of the examples of utilising waste as the component of Atpolan 80 EC in agriculture. When the Atpolan concentration comprised 1.25% (v/v), the atrazine degradation rate decreased in the sandy loam and muck soil. The half-life of atrazine increased over a period of 40 or 57 days, depending on the type of the soil. The least significant effect was caused by Atpolan concentration at 0.25 and 0.75%. This result points at the capability of limiting atrazine run-off and leaching down the soil profile. Each ingredient of the pesticide, besides having the overall ability to distribute between different phases, also demonstrates some single compound behaviour. This paper shows our current understanding of the factors that influence the adjuvant performance and their potentially complex interactions with the pesticide.

Opis:
Research background: China's economic growth, however remarkable, is due to the Harrod-Domar nature of economic growth and, therefore, limited. The main limitation lies in the extension of the neoclassical growth model and the government need to decrease regional disparities using new migration, urbanization and social policy. Purpose of the article: It is the rising regional disparity in the total factor productivity to cause the income inequality increase (measured by GINI index) in China from 1952-2017. Our paper brings new insight into the main inequality determinants and causes in China, using a fractional integration modeling framework. Methods: Using fractional integration, we find total factor productivity (TFP), real gross domestic product per capita and growth and expenditures for the social safety net and employment effort to have a statistically significant impact on GINI. Income inequality in China is of a persistent nature with the effects of the shocks affecting the GINI index enduring over time. Findings & value added: The results of this study highlight the importance for model/policy changes by the policy makers and practitioners in China to deal with the inequality issue. This involves improving the growth model through innovation and technological advancement, relaxing TFP dependence on the physical inputs (labor and capital) to reduce income inequality.

Introduction: Volition is a determinant psychological factor in the improvement of the performance of the human behavior. The aim of the study was to analyze the volitional qualities; persistence, purposefulness and expediency based on personal characteristics and disability-related characteristics. Material and methods: The participants in this study were 140 people with physical disabilities (n=107 men, and n=33 women) while 10 people did not state their gender. Their age ranging from 14 to 67 years. The participants filled the questionnaire Measure Athletes' Volition-Short (MAV-S). In addition following factors were put into analysis: gender, age, family status, education, occupational status, disability [congenital versus acquired], type of disability [spinal cord injury, brain palsy, amputation, poliomyelitis, muscular dystrophy and other type], form of exercise [sport activities - competitive versus recreational - and any activity], type of sport [team versus individual sports], type of experience [resistance, strength and skills], and form of games [Paralympic, European, National and Sectional]). Results: show that the people with physical disabilities who mainly take part in, physical activities manifest a high level volitional qualities (persistence, purposefulness, and expediency). Conclusions: Personal characteristics like form of exercise, type of sport (team, individual) and athletic experience play a moderating role in the existence of individual differences in volitional qualities.

Essential oils as alternative synthetic pesticides for pest management of foodstuffs have recently received increased attention. Controlled and slow release formulations of essential oils are used to enhance their efficiency. Two volatile essential oils of Mentha piperita L. and Salvia officinalis L. were investigated for release rate and mortality percentage by fumigant toxicity against 1st instar larvae of Plodia interpunctella. Electrospinning was used to incorporate various concentrations of essential oils in nanofibers. Th e essential oils can be released from the nanofibers for long periods of time, from several days to several weeks. Poly(lactic acid) was used as a green polymer carrier and the essential oils were incorporated into the nanofi bers (8–15v/v% PLA). Insecticidal bioassay revealed that oil-loaded nanofibers (NFOs) were more toxic than pure essential oils (PEOs) against tested larvae. Th e LC50 and LT50 of NFOs were 1.2 and 4 times, respectively, more than PEOs. Our results indicated that PEOs completely lost their insecticidal activity after 14 days, whereas at the same period, NFOs had an average of 93% mortality when applied against P. interpunctella. Therefore, it can be concluded that nanofibers improved the persistence of the oil. This study presents S. officinalis has more toxicity and M. piperita had more persistence for controlling the larvae of indian meal moth.

Opis:
In the majority of large cities in Poland there is a migration outflow, resulting mainly from suburbanisation processes. However, it should be noted that the inhabitants of large cities do not move exclusively to the suburban zone. The study below focuses on the migratory outflow of Wrocław residents. The authors characterise it by presenting the directions of population movements and determining their sustainability. The authors conclude that the target area of immigrants from Wrocław is mostly a suburban area, but there are also permanent migration flows to other rural communities in the voivodeship and other large cities in the country. The area of emigration itself goes beyond the scope of the voivodeship of which Wrocław is the capital.

Studies about the transition to university emphasise the importance of the process of adaptation in the first year as a determining persistence factor. This article presents the results of the focus groups held with students of two undergraduate degree programmes, Pedagogy and Business Management and Administration, at the Universityof Barcelona(Catalonia, Spain) that dealt with the more significant situations they experienced in the process of adapting to life at university. The results are based on the five main tasks in the process of transition to university: starting and developing new social relationships; adjusting expectations about the university and degree programme; adapting to new academic codes at university; coping with academic/exam results; and construction of the university identity. These five tasks are identified in three moments in the initial period of adaptation. This study forms part of a Research+Development project.

The paper presents an original method of calculation of the fatigue persistence based on the adoption of the load spectrum in the form of a correlation table, two-parameter fatigue characteristics and the linear hypothesis of fatigue damage summation. The calculation results by the proposed method were compared with the results of fatigue tests programmed for node-seal construction. On the basis of a comparative analysis of the test results and calculations conclusions regarding the usefulness of the proposed method to evaluate the fatigue persistence of components have been reached.

Opis:
It is God who is the subject of creatio continua; in Christianity it is a triune God. Fundamentally divine nature, Divine Persons: God the Father, God the Son and the Holy Spirit, who in the logic of the internal life of the Trinity is third and in relation to the world the most direct. The personal specificity of the Third Divine Person predestines it to activity, creativity, to stirring creative power and action in created beings. The Holy Spirit develops and unites, creates the interior of the beings, combines them and strengthens the link with the Creator. This ongoing creation is encoded in the act of creation and is in keeping with the workings of Providence, which also is a creation of the Trinity, and indirectly a creation of people: individuals and societies. Participation in the act of creation stands in proportion to the growth in holiness, which means it is proportional to becoming a person. Created beings personalize themselves through participation in creatio continua, and by participating in this act, they personalize themselves. All this is implemented though the activity of the intellect, will and emotions. It is Jesus Christ in his capacity of God and man who occupies the centre stage of the ongoing creation.

In this paper we derive a model describing the dynamics of HIV-1 infection in tissue culture where the infection spreads directly from infected cells to healthy cells trough cell-to-cell contact. We assume that the infection rate between healthy and infected cells is a saturating function of cell concentration. Our analysis shows that if the basic reproduction number does not exceed unity then infected cells are cleared and the disease dies out. Otherwise, the infection is persistent with the existence of an infected equilibrium. Numerical simulations indicate that, depending on the fraction of cells surviving the incubation period, the solutions approach either an infected steady state or a periodic orbit.
