In bodybuilding, the physical training takes different aspects, in particular the relationship with a specific diet and a substantial contribution of nutritional supplements. The diet for amateur bodybuilders is usually poor, having a negative impact in achieving sportive performance, because the muscle strengthening is closely bounded to vitamins, proteins, carbs, minerals, etc. In this study we have tested the hypothesis according to which in bodybuilding, achieving a good physique and sportive performance is not possible without nutritional supplementation. The study revealed that the athletes manifest a great interest into diet, corroborated with a protein supplementation in different concentrations.

Our study investigated racial profiling of Black youth in Toronto and linked this racial profiling to urban disadvantage theory, which highlights neighbourhood-level processes. Our findings provide empirical evidence suggesting that because of racial profiling, Black youth are subject to disproportionately more stops for gun-, traffic-, drug-, and suspicious activity-related reasons. Moreover, they show that drug-related stop-and-searches of Black youth occur most excessively in neighbourhoods where more White people reside and are less disadvantaged, demonstrating that race-and-place profiling of Black youth exists in police stop-and-search practices. This study shows that the theoretical literature in sociology on neighbourhood characteristics can contribute to an understanding of the relationship between race and police stops in the context of neighbourhood. It also discusses the negative impact of racial profiling on Black youth.

Background: The use of nutritional supplementation of the brewer&#039;s wort can be an interesting option to increase cell viability and yeast fermentability. </P><P> Objective: This study aims to evaluate the effects of the variables wort concentration and nutritional supplementation with palm oil in the production of beer in high-density wort. </P><P> Methods: The process effects were evaluated through the central composite rotational design of type 22 associated with the Response Surface Methodology (RSM). The fermentations were carried out using the commercial Saccharomyces cerevisiae yeast, lager type, at 15&#176;C. </P><P> Results: The mathematical models and RSM obtained were an efficienct strategy to determine the optimum fermentation point for the ethanol volumetric productivity (wort concentration of 20.90 &#176;P and palm oil content of 0.19 % v/v) and for the apparent degree of fermentation (wort concentration of 16.90 &#176;P and palm oil content of 0.22% v/v). There was a good correlation between the experimental values observed and predicted by the model, indicating that the fit of the model was satisfactory and it can be inferred that the increase of the wort concentration and the nutritional supplementation with the palm oil reached an ethanol volumetric productivity of 0.55 g/L.h and an apparent degree of fermentation of 50.20 %. </P><P> Conclusion: Therefore, it can be concluded that our study demonstrates that nutritional supplementation with palm oil is an alternative and promising option for the breweries to increase productivity. There are recent patents also suggesting the advantages of using alternative nutritional supplements in beverage production.

Abstract Apolygus lucorum (Meyer-Dür) (Hemiptera: Miridae) tends to feed on young plant tissues. To explore the relationship between stylet probing behaviors of adult A. lucorum and conditions of cotton leaves, we conducted an experiment using electropenetrography (EPG). Behaviors were recorded on four cotton varieties, in relation to thickness and biochemical traits of differently-aged leaves. Cotton leaf age had a significant effect on the probing behavior of A. lucorum but cotton variety did not. One-day-old leaves of A. lucorum received the highest mean number of stylet probes (penetrations) per insect, and longest mean durations per insect of combined stylet probing or its components, cell rupture and ingestion behaviors. All of the leaf traits (thickness and biochemical substances) were similar among these four cotton varieties. Leaf thickness had a significantly negative effect on the same four variables above. Gossypol and tannin also had a negative impact on combined probing duration. Redundancy analysis showed that the four EPG variables were closely related to nutrient substances (amino acids, sugar, and water) while they had the opposite relationship with plant defense substances (gossypol and tannin). On cotton in the seedling stages, A. lucorum fed more readily on the youngest, thinnest leaves in our no-choice EPG experiments. Nutrients and chemical resistance substances determined the probing duration of A. lucorum. Our findings can contribute to better understanding of patterns of feeding and host consumption by A. lucorum, ultimately improving cotton resistance to A. lucorum.

The aim of this study was to analyze athletes’ quality of life during the COVID-19 pandemic. The study involved 249 athletes between 15 and 35 of age, M = 21.22, SD = 5.12. The sample was composed of eight Olympic Games medalists, three European medalists, 67 international medalists, and 63 national medalists. The instruments used were: (1) COVID-19 Anxiety Scale, (2) Athlete Quality of Life Scale, (3) Impact of Pandemic on Athletes Questionnaire, and (4) International Personality Item Pool (IPIP Anxiety, Depression, and Vulnerability Scales). The results indicate significant differences in COVID-19 anxiety depending on the sport practiced, F (9239) = 3.81, p < 0.01, showing that there were significant differences between sports. The negative impact of the COVID-19 pandemic mediates the relationship between trait anxiety and the athletes’ quality of life. The percentage of mediation was 33.9%, and the indirect effect was −0.11, CI 95% (−0.18, −0.03), Z = −2.82, p < 0.01. Trait anxiety has an increasing effect on the intensity of the negative impact of the COVID-19 pandemic, 0.23, CI 95% (.10, 0.35), Z = 3.56, p < 0.01, and the negative impact of the COVID-19 pandemic has a decreasing effect on quality of life, −0.47, CI 95% (−0.67, −0.27), Z = −4.62, p < 0.01. Gender and age did not moderate the relationship between the negative impact of COVID-19 and athletes’ quality of life. The results of the study highlighted the impact that social isolation and quarantine have on athletes’ affective well-being.

Abstract This presentation describes a supportive mindfulness practice for caregivers of older adults based on the principles of Won Buddhism (an integrative, a modernized Buddhism). As the aging population grows, there is a significant increase in recognition of the negative impact of caregiver stress on older adults’ quality of life. The ability for caregivers to deal compassionately with stress is essential, as caring for older adults can awaken feelings about one’s own vulnerability and mortality. The ‘Mindful Gratitude Practice’ offers a way to cope with stress, cultivate self-care, and improve the care of others. Relevant research will be summarized, which shows mindfulness and gratitude practice respectively benefit positive influence in both physical and emotional well-being. Mindful Gratitude Practice as a spiritual approach that fosters caregivers' emotional stability, reduces their stress and improves the relationship between older adults and their caregivers. In this presentation, three processes of Mindful Gratitude Practice will be described: 1. Understanding a mindfulness practice by establishing intention, attention, and attitude, 2. Learning the principles of a gratitude practice and implementation, and 3. Incorporating mindfulness into a gratitude practice. Research results have demonstrated that through this learning process, caregivers have acquired the concept of interconnectedness, experience grateful moments, and a deep feeling of appreciation in their caregiving relationships. The presenter will guide participants in a short experience of Mindfulness Gratitude Practice. Further readings and resources will be provided for those who are interested.

Purpose This paper aims to clarify the mechanism by which heuristics influences the investment decisions of individual investors, actively trading on the Pakistan Stock Exchange (PSX), and the perceived efficiency of the market. Most studies focus on well-developed financial markets and very little is known about investors’ behaviour in less developed financial markets or emerging markets. The present study contributes to filling this gap in the literature. Design/methodology/approach Investors’ heuristic biases have been measured using a questionnaire, containing numerous items, including indicators of speculators, investment decisions and perceived market efficiency variables. The sample consists of 143 investors trading on the PSX. A convenient, purposively sampling technique was used for data collection. To examine the relationship between heuristic biases, investment decisions and perceived market efficiency, hypotheses were tested by using correlation and regression analysis. Findings The paper provides empirical insights into the relationship of heuristic biases, investment decisions and perceived market efficiency. The results suggest that heuristic biases (overconfidence, representativeness, availability and anchoring) have a markedly negative impact on investment decisions made by individual investors actively trading on the PSX and on perceived market efficiency. Research limitations/implications The primary limitation of the empirical review is the tiny size of the sample. A larger sample would have given more trustworthy results and could have empowered a more extensive scope of investigation. Practical implications The paper encourages investors to avoid relying on heuristics or their feelings when making investments. It provides awareness and understanding of heuristic biases in investment management, which could be very useful for decision makers and professionals in financial institutions, such as portfolio managers and traders in commercial banks, investment banks and mutual funds. This paper helps investors to select better investment tools and avoid repeating expensive errors, which occur due to heuristic biases. They can improve their performance by recognizing their biases and errors of judgment, to which we are all prone, resulting in a more efficient market. So, it is necessary to focus on a specific investment strategy to control “mental mistakes” by investors, due to heuristic biases. Originality/value The current study is the first of its kind, focusing on the link between heuristics, individual investment decisions and perceived market efficiency within the specific context of Pakistan.

The Relationship

Teaching is one of the professions with the highest levels of stress and disquiet at work, having a negative impact on teachers’ well-being and performance. Thus, well-being is one of the priorities in human resource management (HRM) in schools. In this regard, this paper studies the relationship between HRM, well-being and performance, observing the incidence of leadership and innovation in these relationships. The objective is to measure the extent to which it is necessary to encourage sustainable environments that promote the well-being of teachers and, by extension, students. The study used the methodology of structural equations and a sample of 315 secondary school teachers. The work validates the influence of leadership by example and information management on HRM and performance. In addition, we confirm the significant effect of human resource management on educational performance. The relationship is observed both directly and through the mediating effect on the improvement of well-being. On the other hand, the positive influence of innovation on performance, both in schools and in the classrooms, is reaffirmed. These results suggest the need to zero in on the human resources policies in schools linked to the improvement of teacher well-being and educational performance. They also highlight the role of school and classroom innovation as a key element in maintaining educational quality.
