Opis:
Statistical analysis is a crucial step in all experimental studies, including sport sciences, because inappropriate analysis can lead to erroneous assumptions of performed experiments. Statistical analyses of the training-related data are required to make the training process more efficient. The analyses of various parameters are performed in repeated cycles, requiring appropriate statistical tests. STATISTICA software (version 10) offers a Friedman test for non-parametric analyses of more than 2 groups of repeated measures (which often takes place). Unfortunately, there is no post hoc test to verify which groups decide of the statistical significance of the results. The solution to this problem may lie in the normalization of the data with one of the most popular logarithmic transformations. It allows performing multiple comparisons for the 1-way ANOVA with repeated measures, as well as appropriate post hoc test to precisely determine which group of data is responsible for the statistical significance of the differences.

Opis:
This study aimed to verify the psychometric properties of the Polish version of the Grit-S questionnaire. Grit is understood here as the perseverance and passion for long-term goals, and it encompasses two dimensions: Consistency of Interest and Perseverance of Effort. The sample comprised N = 270 participants aged 18–34 (Mage = 20.79). We performed confirmatory factor analyses to verify the dimensional structure of grit, multi-group confirmatory factor analysis to compare the structure across gender, and correlation analysis to examine external validity (exploring the correlations between grit, procrastination, and well-being). Findings showed satisfactory parameters for Grit-S including: reliability, structural and external validity, and measurement invariance across gender groups. The results support the possibility of using the Grit-S questionnaire in research exploring the predictors of success.

Opis:
The paper applies RT to analyse an 18th century translation of a Latin text by the preeminent Romanian scholar Demetrius Cantemir. The translation diverges significantly from the original and was met with harsh criticism. Using the conceptual toolkit of RT, I argue that the differences between the original and its English translation were motivated by the translator’s desire to yield the same cognitive effect without putting the audience to unnecessary processing effort. Both effects and effort need to be evaluated by taking into account the respective cognitive environments of the source-text and the target-text audiences. The intertextual dimension of the text under scrutiny adds to the difficulty of communicating the same message in different languages and cultures.

The article reports on a device for book block spines processing that was designed and assembled on a perfect binding machine Trendbinder. The article shows workability of designed device. The authors have developed a methodology for the experimental study of the tractive effort of chain conveyors by technological load, the wireless module for data measurement and software for its processing. Extensive coverage is given to experimental research of the tractive effort of chain conveyors during book block spine processing depending on book block velocity, type of paper from which they are made and setting angle of cylindrical milling cutter relatively to direction of book blocks movement. The authors have examined the change in the tractive effort. The article experimentally confirms that sluggishness of chain drive causes vibration of the tractive effort. This effect can be observed during free-running movement of chain with carriers of perfect binding machine as well as during technological load influence. The article describes that between research parameters the setting angle of cylindrical milling cutter has the main impact relatively on the direction of book blocks movement.

priority forcing scheme
Opis:
The paper presents recent results corresponding to a new strategy for source traffic generating, named priority forcing scheme (PFS), allowing Internet users for getting better than best effort service in IP network. The concept of PFS assumes that an application, called PFS application, sends to the network a volume of additional traffic for the purpose of making the reservations for the data traffic in the overloaded router queues along the packet path in the IP network. The emitted redundant packets, named R-packets, should be rather of small size comparing to the data packets, named D-packets. The PFS scheme assumes that the R-packets waiting in a queue can be replaced by the arriving D-packets and belonging to the same flow. In this way, the D-packets can experience a prioritised service comparing to the packets produced by a non-PFS application. Notice that the proposed solution does not require any quality of service (QoS) mechanisms implemented in the network, like scheduler, dropping, marking etc., except R- and D-packets identification and replacing. We discuss the PFS efficiency for forcing priority in the overloaded conditions. Moreover simple system analysis is also presented. Finally, the profits of using PFS scheme are illustrated by examples corresponding to FTP (TCP controlled traffic) and VoIP (UDP streaming traffic) applications.

In their attempts to find the most acceptable variant to unite antiquity and modern literature and art, we see great influence of the ideas and poetry of Lecont de Lisle.

Opis:
Objectives Occupational stress is a common complaint in nurses, who perceived more sense of effort-reward imbalance (ERI). Suboptimal health status (SHS) is a state between health and disease. However, the correlation between ERI and SHS is unclear. Therefore, the aim of this study was to examine the prevalence of SHS and ERI and evaluate the relationship between ERI and SHS in clinical nurses by a cross-sectional study. Material and Methods The current cross-sectional study was conducted through an online survey at Dongping People’s Hospital in China. A total of 633 completed surveys were received. Effort-reward imbalance was measured by subscales of the ERI questionnaire. SHS was measured by the Suboptimal Health Status Questionnaire – 25 (SHSQ-25). The relationship between ERI and SHS in nurses was subsequently assessed by Spearman’s correlation coefficient and logistic regression model. Results The mean age of the optimal health status (OHS) group (M±SD 26.3±7.3 years) was younger than the SHS group (M±SD 30.3±6.9 years). The prevalence of SHS was 54.5% (345/633). Female nurses aged ≥30 years, a junior college or university graduate educational level, smokers, and nurses without regular exercise were at a higher risk of SHS. In Spearman’s correlation analysis, ERI reflected by the effort-reward ratio was correlated with SHSQ-25 score (r = 0.662, p < 0.001). In logistic regression, ERI was strongly associated with SHS after potential confounding factors adjusting (OR 27.924, 95% CI 22.845–34.132). Conclusions The prevalence of SHS was significantly high in clinical nurses. Administrators should pay more attention to health status of female nurses aged ≥30 years, with a junior college or bachelor’s degree, smoking, and without regular exercise to reduce the SHS and ERI.

Opis:
The main aim of this article is to submit an idea of the structural balance within the euro area fiscal surveillance framework, characterising its main methodological aspects and analysing the level of structural balance in the euro area countries in the time of recovery from the financial crisis. Since the first reform of the Stability and Growth Pact, which took place in 2005, structural balance has played the key role as an indicator of fiscal surveillance in the euro area. This balance is cyclically adjusted net of one – off and temporary measures. It enables to estimate the level of fiscal consolidation measures, which are being introduced by the euro area countries, and recognise the results of the actions taken.
Głównym celem artykułu jest przedstawienie istoty salda strukturalnego w nadzorze fiskalnym strefy euro, scharakteryzowanie jego głównych aspektów metodycznych, oraz analiza kształtowania się tego salda w krajach strefy euro w okresie wychodzenia z kryzysu. Od czasu pierwszej reformy Paktu Stabilności i Wzrostu, która miała miejsce w 2005 r., saldo strukturalne odgrywa kluczową rolę w nadzorze fiskalnym w strefie euro. Saldo to jest dostosowane cyklicznie, bez uwzględnienia środków jednorazowych i tymczasowych. Umożliwia ono oszacowanie rozmiaru działań konsolidacyjnych wprowadzanych przez kraje członkowskie oraz rozpoznanie rezultatów tych działań.

Opis:
All constructions are subject to the most compound loads and therefore a suitable effort hypothesis should be used for their calculation. For anisotropic materials, a hypothesis should be used to describe the properties of such materials. In the work have been shown the strength of the layers composite on the example of construction wood in a compound stress state. Wood composite is an orthotropic material. Wood is composed of alternating layers of soft wood and hard wood. Single layers are monotropic material. The use of a stress hypothesis, which describes the strength of an orthotropic material, requires will make an investigation. Studies is purposed to determine the tensile strength along and across the fibres. The compressive strengths along and across the fibres and the shear strength. Particularly the determination of shear strength requires special tooling so that in the case of flat samples in the measuring part it is possible to determine the shear stresses. Therefore, a research stand was designed and constructed. Known stress hypotheses for anisotropic materials have been analysed. The analysis showed that the strength of the wood composite could be described by the Tai-Wu stress hypothesis. Based on the results of the research, numerical calculations were performed. Calculations allowed determining the distribution of stresses in the sample measuring part. The results tests and numerical calculations have shown that obtaining a homogeneous stress (shear) condition for anisotropic materials is very difficult. Wood belongs to materials whose mechanical properties depend on many parameters, so the description of the effort of this material is a compound issue. Studies have shown that wood reinforcement by polymer saturation is best suited to the compressed loaded structures.

Opis:
By ustalić przydatność katecholamin w ślinie do badania stresu, pobrano próbki od 30 studentów przed egzaminem oraz w dniu pozbawionym stresorów. Następnie aby zbadać wpływ wysiłku poznawczego na poziomy katecholamin, przebadano 31 ochotników, którzy uczestniczyli w dwóch spotkaniach poświęconych realizacji różnych testów poznawczych. Za pomocą HPLC-ED zmierzono poziomy noradrenaliny, dopaminy i adrenaliny w ślinie. W grupie przed egzaminem zaobserwowano wyłącznie obniżony poziom dopaminy w porównaniu do dnia nieobciążonego stresorami. W drugiej grupie wysiłek poznawczy wywołał podwyższenie poziomów wszystkich trzech katecholamin. Zważywszy na niejednoznaczne wyniki z dotychczasowych badań wydaje się, iż adrenalina i noradrenalina w ślinie mogą być stosowane jako markery aktywności współczulnej w badaniach psychologicznych.
In order to determine utility of salivary catecholamines in stress studies, samples were collected from 30 students before an exam and on an ordinary day. Subsequently, to examine the effect of cognitive effort on catecholamines, 31 volunteers, on two days, performed two sets of different cognitive tasks. Noradrenaline, adrenaline and dopamine levels were examined with HPLC-ED. Stressed group shown alleviated levels of dopamine, while levels of other substances remained unchanged. In the second group cognitive effort elicited elevated excretion of all three catecholamines. Given conflicting results from previous literature it appears that salivary adrenaline and noradrenaline might be useful as non-invasive markers of sympathetic activity in psychological research.

Opis:
Objective: Personality dispositions may influence perceptions of work stress. The paper examines the relationship between temperament in terms of Strelau's Regulative Theory of Temperament and the effort-reward imbalance and its components. Material and Methods: There were 890 participants (360 men) aged 37.9 years on average. Temperament traits of briskness and perseveration (temporal characteristics of behavior), sensory sensitivity, emotional reactivity, endurance and activity (energetic characteristics of behavior) were measured by Strelau & Zawadzki's Formal Characteristics of Behavior-Temperament Inventory (FCB-TI) in 1997 and 2001. Effort and reward at work were assessed with the original effortreward imbalance (ERI) questionnaire of 2007. Results: Higher ERI at work was predicted by higher emotional reactivity, higher perseveration, lower briskness, and lower endurance. Higher effort and lower rewards at work were predicted by higher perseveration and lower endurance. The FCB-TI temperament characteristics accounted for 5.2%, 4.8% and 6.5% of the variance in the ERI, effort and reward, respectively. Lower emotional reactivity, lower perseveration, higher briskness and higher endurance predicted higher esteem at work, job promotion and job security. Conclusions: Individual differences in arousability, reflected in temporal and energetic characteristics of behavior, may predispose to or to protect from an effort-reward imbalance at work. Individual differences should be acknowledged in work stress prevention and developing interventions.

Opis:
The paper reports experimental research on torques during cardboard cutting in the die-cutting press with eccentrics in the drive of the movable pressure plate. To conduct the research, an experimental bench with eccentrics in the drive of the die-cutting press is designed and manufactured. The manufactured experimental device for the research on cardboard blanks provides the possibility of getting dependencies of loadings at different parameters of the die-cutting process. The experimental approach envisages the use of the strain gauge measurement method and the wireless module for data collecting, as well as the software for its processing, for getting trustworthy results with minimum faults. The method gives an opportunity to study the torque values during the cardboard-cutting efforts on the drive shaft. The paper shows changes in the torque value on the drive shaft during the kinematic cycle with and without the use of cardboard blank. The angle of the drive shaft rotation during the cutting process was evaluated at selected values of the cardboard thickness. The relationship between the linear cutting efforts and the cardboard thickness, its fibre direction, cutting rule type and rotational speed of the drive shaft is elaborated. This kind of data is approximated by a logarithmic function (logarithmic curve), at R2 from 0.90 to 0.98. The thickness of the cardboard significantly influences the value of the linear cutting effort at all the studied parameters.
