Structure of achievement motivation dispositions in elite and non-elite track and field athletes

Achievement motivation is a distinguishing disposition in elite and non-elite athletes. Implicit theories and competence perception influence the types of achievement goals and constitute separate achievement motivation dispositions. The context of sport promotes various achievement goals and implicit theories about athletic competence. For this reason, scientific research should focus on the intrapersonal profiles of achievement motivation dispositions (achievement goals, implicit theories, and competence perception) instead of specifying only one of them. This study explores differences between elite and non-elite athletes in terms of intrapersonal profiles of achievement motivation dispositions. 54 elite and 50 non-elite track and field athletes took part in the study. The results suggest that athletes tend to perceive their competence accurately. Cluster analysis of the studied dispositions was conducted. The clusters present sets of achievement dispositions that vary in intensity. Moreover, the results present trends of the differences between elite and non-elite athletes in two of the three clusters obtained in the study

Stem photosynthesis : a key element of grass pea (Lathyrus sativus L.) acclimatisation to salinity

Grass pea (Lathyrus sativus) is a leguminous plant of outstanding tolerance to abiotic stress. The aim of the presented study was to describe the mechanism of grass pea (Lathyrus sativus L.) photosynthetic apparatus acclimatisation strategies to salinity stress. The seedlings were cultivated in a hydroponic system in media containing various concentrations of NaCl (0, 50, and 100 mM), imitating none, moderate, and severe salinity, respectively, for three weeks. In order to characterise the function and structure of the photosynthetic apparatus, Chl a fluorescence, gas exchange measurements, proteome analysis, and Fourier-transform infrared spectroscopy (FT-IR) analysis were done inter alia. Significant differences in the response of the leaf and stem photosynthetic apparatus to severe salt stress were observed. Leaves became the place of harmful ion (Na+) accumulation, and the efficiency of their carboxylation decreased sharply. In turn, in stems, the reconstruction of the photosynthetic apparatus (antenna and photosystem complexes) activated alternative electron transport pathways, leading to effective ATP synthesis, which is required for the efficient translocation of Na+ to leaves. These changes enabled efficient stem carboxylation and made them the main source of assimilates. The observed changes indicate the high plasticity of grass pea photosynthetic apparatus, providing an effective mechanism of tolerance to salinity stress

Person – job fit in students’ perspective and its consequences for career aspirations

PURPOSE: The purpose of this article is to examine the relationship between students’ dedication (S_DED) and their perception of person-job fit (P_J Fit) and investigate how it correlates with students’ career aspirations (CAREER_ASP). Additionally, the relationship between perceived P_J Fit and students’ work experience (WORK_EXP) and social support (S_SUPPORT) have been analyzed.DESIGN/METHODOLOGY/APPROACH: This study was conducted among tourism and/or hospitality students of two universities that agreed to participate in the study. They are located in cities of Poland and Croatia which are very attractive tourist destinations. The questionnaires were administered in each institution and the auditorium survey technique was applied to gather the data.FINDINGS: The findings of this study revealed that there is a positive and significant correlation between students’ dedication and their perception of person-job fit. It was also indicated that there is a positive and significant correlation between students’ work experience, students’ social support and perceived P_J Fit. Finally, it was proved that the more students perceive their skills and abilities as matching the requirements of their future work, the more they believe they can pursue a career in this field.PRACTICAL IMPLICATIONS: It is recommended that the educators pay more attention to the person-job fit of students when recruiting them for T&H courses at higher education institutions. Moreover, it is important to offer a variety of activities to increase students’ dedication to the studies undertaken. Specifically, for curriculums to be suitable and to generate enthusiasm among students, they should be customized to meet the requirements of the labor market and modern teaching techniques should be applied to actively engage students in the learning process, making it challenging.ORIGINALITY/VALUE: To the best of the authors’ knowledge, this study is one of the first to focus on identifying factors relating to students’ perception of their P_J Fit by linking it with their career aspirations in a single research model.peer-reviewe

Human Resource Management in Chain Hotels on the Example of Radisson Blu Hotel in Szczecin

Chain hotels differ from independent hotels in very many features. One of them is human resource management, what stems from the fact that personnel policy of a chain hotel is thoroughly devised. All aspects related to it have to be precisely described and rather universal since they concern employees working all around the world, that is personnel representing various nations, cultures, outlook on life, etc. The article consists of three substantive parts, an introduction and a conclusion. The first part of the article, which is theoretical, concerns human resource management and its significance in the hotel industry. The next two parts are analytical and empirical (in the form of case study) and they describe basic organizational areas of functioning of the Radisson Blu hotel in Szczecin and particular human resource management tools in the analysed hotel

Instruments for managing the EU labour market in the face of the COVID-19 crisis

Purpose: The article presents in a multifaceted manner the instruments used in the EU member states to mitigate the effects of the COVID-19 pandemic in the labour market. Design/Methodology/Approach: Theoretical issues were examined on the basis of the analysis of available source literature on labour market economics and risk management. The research methods used in this paper include, critical analysis of the source literature, the method of comparative analysis and secondary data analysis. Findings: The article identifies actions taken by the EU member states to support the labour market and to develop a model of instruments intended for EU authorities and member states to reduce the risk of labour market disturbances during the COVID-19 pandemic. Practical Implications: The analysis and evaluation carried out in the article indicated that risk management on the EU labour market during the pandemic requires integrated protective measures. The results obtained may be used to formulate a long-term strategy for the EU labour market and programmes to counter the effects of the crisis. Originality/value: The issues as presented in the article concerning the instruments used to manage the EU labour market in the era of the COVID-19 pandemic have not been studied in Polish and foreign literature.peer-reviewe

Enrichment of maternal diet with conjugated linoleic acids influences desaturases activity and fatty acids profile in livers and hepatic microsomes of the offspring with 7,12-dimethylbenz[a] antracene- induces mammary tumors

The aim of this study was to assess the influence of diet supplementation of pregnant and breastfeeding female Sprague-Dawley rats with conjugated linoleic acids (CLA) on the Δ6- and Δ5-desaturase activity in hepatic microsomes as well as on fatty acids profile and lipids peroxidation in liver and hepatic microsomes of the progeny with chemically induced mammary tumors. Rats were divided into two groups with different diet supplementation (vegetable oil (which did not contain CLA) or CLA). Their female offspring was divided within these groups into two subgroups: (1) ñ fed the same diet as mothers (K1 ñ oil, O1 ñ CLA), and (2) ñ fed the standard fodder (K2, O2). At 50th day of life, the progeny obtained carcinogenic agent (7,12- dimethylbenz[a]anthracene). Higher supply of CLA in diet of mothers resulted in lower susceptibility to chemically induced mammary tumors in their offspring (p = 0.0322). It also influenced the fatty acids profile in livers and in hepatic microsomes, especially polyunsaturated n3 and n6 fatty acids. CLA inhibited the activity of the desaturases, which confirmed that CLA can reduce the level of arachidonic acid directly, reducing linoleic acid content in membranes, or indirectly, through the regulation of its metabolism. We were unable to confirm or deny the antioxidative properties of CLA. Our results indicate that the higher supply of CLA in mothersí diet during pregnancy and breastfeeding causes their incorporation into tissues of children, changes the efficiency of fatty acids metabolism and exerts health-promoting effect in their adult life reducing the breast cancer risk
