Background: Athletes, coaches, sport psychology practitioners, and researchers suggest that mental toughness represents an important construct that is associated with athletic performance. Unfortunately, the absence of real-world performance as a dependent variable has limited our ability to substantiate this claim. The concern of a lack of ecologically valid measures of sports performance might be addressed by examining the relationship between mental toughness and sports performance using a standardized measure of personal best(PB) triathlon time and a validated unidimensional measure of mental toughness.Methods: Three hundred and sixteen triathletes completed the 8-item mental toughness index(MTI), reported their age, and provided a PB Olympic distance triathlon time and the total number of triathlons they had completed to date. Given that males are typically quicker than females, a standardized time was calculated by dividing the PB by the current Olympic record for gender; we also hypothesized that more experienced triathletes would report quicker PB times because of greater frequency and duration of training. Once we had controlled for gender and experience,we predicted that mental toughness would be negatively associated with triathlon time and the size of the relationship would be of a moderate magnitude.Results: Results revealed small-to moderate-sized negative relationships between both completed number of triathlons and mental toughness with standardized PB time.Conclusion: The hierarchical regression analysis showed that mental toughness provided a unique contribution to the variability in standardized Olympic triathlon PB after controlling for the total number of triathlons completed. 展开更多

Background: Pharmacists must adjust their distance from patients to facilitate communication during interviews and gain their trust. The distance between the patients and the pharmacists varies depending on many factors, such as gender, posture and the patients’ mood. Only a few of these papers have actually measured and validated distance with patients. In this study, we validated our method of assessing mood and measuring distance before beginning a survey with patients. Methods: We measured comfortable interpersonal distance among men and women using an ecological scenario, in which a pharmacist approaches the subject, and the subject is asked to stop the pharmacist at the distance he/she feel comfortable with. Five pharmacists and 33 subjects participated in the study. The Japanese version of the Brief Mood Questionnaire Checklists (BMC-J) was used to quantify the subject’s mood for the day, and then the distance from the pharmacist that the subjects considered comfortable was measured at the bedside. The relationship between the mood and distance obtained was examined. Results: The comfortable distance of subjects was influenced by gender, posture, and mood. The shortest distance was 94.7 ± 11.1 cm (mean ± SD), for the male subjects versus the female pharmacists in the sitting position. The distance of male subjects shorted when they had positive emotions and lengthened when they were worried. Female subjects maintained a long distance from both male and female pharmacists when they had positive emotions and a short distance when they were worried. Conclusion: Findings show that the distance changes depending on the subjects’ mood at the time of measurement. It was found that the present measurement method can be used to determine the psychological state of the patient and measure the comfort distance at that time, and can be used as a simple method to examine these relationships. Therefore, it is also considered a practical method for the next step, which is a clinical study on patients. 展开更多

As the second bestseller of Khaled Hosseini' s novels that spread all over the world,A Thousand Splendid Suns embodies the quite impressive and infective writing techniques and narrative power of its writer and it also shows the unique language style of Hosseini.This paper gives an explanation of the narrative point of view and analyses the specific examples in the text.Through deepening the transition of third-person point of view between the two characters,the paper demonstrates its stylistic effects in arranging the textual structure as well as building the characters,thus deepen the theme of the whole story. 展开更多

The goal is to utilize the observed data. The way that we have used in this paper is based on two observational data in Iran (Mashhad 36°31′ N, 59°48′ E) and Canada (Yukon Territory 69°27′ N, 33°2′ E). It is required to mention that in Mercury transition 2016, I had personally collected the first place, Mashhad. In measuring the distance between Mercury and the Sun we have utilized the trigonometry terms and the related formulas. Using all the collected data and studying on the contacts of the mercury, has helped us to reach the best results. 展开更多

It is known to all that distinct choices of deixis can reflect various meanings underlying the surface level. In addition to conveying a specific reference and inference, it can reflect the people's mental activities. From the perspective of psychological distance, this thesis tends to interpret the connotation underlying the the deixis chosen by those teachers in a thesis defense interview so as to help them better understand their self-identity and psychological. Besides, through this study, the students, who attend the thesis defense interview, are able to improve their capability dealing with those teachers' questions. 展开更多

The aim for this research is to analyze the person deictic expressions in advertising English and to find out their characteristics and possible functions.Advertising has become a very specialized activity in modern times.During the period of development,advertising has performed its own language style,which is quite different from other types of languages.The proper interpretation and use of the language is dependent on its specific situation or context.Person deixis puts the text in a specific situation;the selection of person deixis not only can reflect the physical distance but also indicate the psychological distance between the advertiser and the public.Three categories of person deictic expressions in the advertisements are analyzed to find out frequency of appearance.Statistical results show that more first person and second person pronouns like I,we,and you are used than third person pronouns he,she,they and it,among which the second person pronouns take up the highest rank.On the basis of the frequency of person deictic expressions,this study finds that through the proper use of the person deictic expressions,the advertiser can attract a large number of people in an interactive communication and at the same time,make the advertisement become more cordial,thus greatly shorten the psychological distance between the advertiser and the audience. 展开更多

Faced with many problems (practically insoluble) that call them politicians lie (to save their careers), claiming that they are resolutely interested to earth’s environment protection. Unnecessary (for some) and outrageously expensive (for others) organization of COP21 is part of this logic of distracting the “international community” by (for example) making believe that the reduction of CO<sub>2</sub> emissions is something reachable for humans and that this reduction can weaken the harmful effects of global warming such as: floods, endless droughts, melting glaciers, upsurge of hurricanes or tornadoes, etc. Can the “binding” commitments taken during COP21 be effective? Our objective and immediate answer is: No. Because those who have made commitments, ignore completely how the CO<sub>2</sub> (main object of their attentions) or sulfur dioxide (SO<sub>2</sub>) behave with respect to some predominant elements of the atmosphere such as clouds. Moreover, a significant number of the propaganda forums’ stakeholders ignores that earth’s atmosphere is considerably affected by the radiation from the sun and that the intensity of solar radiation received at the surface of the earth mainly depends on the Earth-Sun distance and the precession angle of the earth relative to its orbit. Earth-Sun distance and precession angle of the Earth’s orbit vary in space and time: this Physical law must be constantly present in our minds. Teaching the fundamentals of Atmospheric Physics allows solar radiation and its derivative forms (e.g.: winds, snow or rains) to cease to be a mystery in the mind of the international community. 展开更多
