Investigation of plyometric and endurance training on athletic performance in female elite rowers(مقاله علمی وزارت علوم)
حوزههای تخصصی:
Background: Plyometric training is defined as a quick, powerful movement involving a system of reactive exercises and an eccentric contraction, followed immediately by an explosive concentric contraction.
Aim : This study aimed to determine the effect of plyometric and aerobic training on peak power and performance in female elite rowers.
Materials and Methods: Sixteen female elite rowers with a minimum of 1 year’s competitive rowing experience were recruited to perform six weeks of plyometric or cycling endurance training for 30 min before practice on the water three days per week. Rowing performance was assessed through a 500-m rowing time trial (TT), while peak rowing power (PR) was evaluated by over three maximal trials of 15 s on the rowing ergometer. The recorded value for peak power was the highest wattage observed during the 15-s period. All statistics were performed using commercially available software (SPSS v. 23, Armonk, NY). Pre-planned t-test comparisons were used to determine significance at baseline in changes within both groups.
Results: The results showed 500-m TT performance significantly improved for the plyometric group ( P < 0.05) but not for the endurance group ( P > 0.05). Moreover, PR was considerably higher in the plyometric group in post-test than endurance training.
Conclusion: These results suggest that plyometric can improve rowing performance in female elite rowers, and rowing coaches should continue using this form of training. Coaches can perform plyometrics in conjunction with other strength training methods or as a warm-up before beginning rowing-specific training.
The Effects of Audience Behaviour on Football Players’ Performance(مقاله علمی وزارت علوم)
حوزههای تخصصی:
Audience behaviour is an external factor which could influence an athlete’s performance during a match due to the evaluative attitude which it might convey. One of the most common positive influences on a team’s motivation can be attributed to a supportive and cheering audience. Contrastingly, jeering can be interpreted as negative influence. High emotions exchanged between the spectators and the players may also show the important ties which bind them together, and this can affect the players’ behaviour on the field of play. This study focuses on how crowd behaviour in Maltese football influences the players’ performance in the game. The influence of spectator behaviour on the psychological state of six male national senior football team members and six male national team youth players was analysed through data gathered from individual semi-structured interviews. Results show that both senior and youth players are influenced by variables of audience behaviour and feel pressured and anxious throughout matches. Incentives for positive behaviour need to be introduced, together with sanctions for the breaking of rules, as well as slogans and placards placed in the stands for further awareness need to become the norm. If we are to curb societal issues such as racism and violence, the need for educational strategies is clear.

حوزههای تخصصی:
In addition to its functional aspects, architecture holds a deeper significance that communicates with the observer or user of the architectural work. Perception plays a crucial role in various fields, as an individual's perceptions, emotions, and mental states, alongside visual characteristics, can lead to diverse or multiple interpretations, allowing the landscape to be understood in myriad ways. Every architectural design maintains a connection with its surroundings through its distinct visual attributes. Aligning with this notion, the present study aims to elucidate the visual aspects of workplace architecture and its impact on the performance of private bank employees in Rafsanjan city. This research adopts an applied developmental goal and employs a descriptive-analytical methodology. Data collection utilized both field methods (public questionnaires) and a combined approach (quantitative-qualitative) for data analysis. Descriptive and inferential statistical techniques were applied using SPSS software. The findings revealed a direct correlation between the visual characteristics of workplace architecture and job performance in private bank branches in Rafsanjan. Thus, emphasizing visual elements in bank architecture holds significant importance, as these factors can influence employee performance, alertness levels, and concentration at work. The visual features of workplace architecture directly impact visual and psychological needs. Therefore, to enhance the performance quality of banks, these characteristics must be regarded as pivotal factors in workplace environments.

حوزههای تخصصی:
Novel viewpoints see the façade as a multi-functional component that should simultaneously meet functional and aesthetic requirements. These requirements need to be evaluated using a state-of-the-art approach. Although façade performance assessments are seen in the literature, studies that investigate the aesthetics and performance of façades rarely can be found together. Reviewing the approaches, methodologies, and criteria utilized to assess façades can draw a vision of the background for those who intend to develop a method for façade evaluation based on a novel perspective. This study aims to investigate recent research to discover approaches to façades. An exploratory case study methodology was applied to implement this aim, while the data collection method was library-based. Content analysis was employed via logical reasoning to determine the approaches, methods, and criteria of façade evaluations. Also, open and axial coding was used to organize the criteria extracted. The found approaches were "sustainability," "buildability," "life cycle assessment," "competing objectives," "performance," and "general," while the most frequent ones were "performance" and "sustainability" after "general." Previous façade-focused research methodologies were concentrated on five methodologies: multicriteria decision-making (MCDM), simulation, optimization, library-based, and hybrid. The most popular method was MCDM. Extraction of criteria demonstrated that "Costs," "Thermal performance," “Environmental impacts,” and “Durability” are respectively the trend ones with the highest frequency of presentation. To conclude, the façade as a multi-functional element needs to be assessed with state-of-the-art methods that consider all the required functions of a façade, including aesthetics. In contrast, Conventional methods cannot provide such a service.
Economic Policy Uncertainty, Credit Risk, and Lending Decisions: Banks Listed on the Tehran Stock Exchange
حوزههای تخصصی:
This research investigates the relationship between Economic Policy Uncertainty (EPU), credit risk, and lending decisions using the Generalized Method of Moments (GMMs)over the period from2019 to 2023 for12banks listed on the Tehran Stock Exchange. The study employs three regression models to analyze the dynamics of Non-Performing Loans (NPLs), Loan-To-Deposit Ratios(LTDRs), and Return onAssets (ROAs)within the banking sector. Findings reveal a significant persistence in NPLs, indicating that banks with higher past NPLs face ongoing challenges that adversely affect their financial health. A notable negative relationship between Leverage(Lev) and Non-Performing Loan Ratio (NPLR)suggests that more leveraged banks may implement effective risk management strategies, reducing their exposure toNPLs. Additionally, capital adequacy emerges as a critical factor, with higher capital ratios correlating with lower NPLs. The analysis of LTDR indicates thatLevand capital adequacy significantly influence lending practices, while a marginally significant relationship between EPU and LTDR suggests external uncertainties may slightly impact lending decisions. Model results further demonstrate strong persistence in profitability, with historical ROA positively predicting current ROA. Overall, this study underscores the importance of effective risk management practices in banking and highlights ongoing challenges posedbyNPLs, particularly for larger institutions. Recommendations include prioritizing capital buffers and monitoring lending practices to mitigate risks while fostering sustainable profitability growth. Future research should explore additional variables to elucidate the complexities of banking performance metrics
