The purpose of this study was to explore the effects of supervised movie appreciation on improving the life meaning sense among college students. The intervention combined by “pre-video, post counseling” was conducted on the experimental group, while the control group received no intervention. Results have shown that the scores on the subscales of will to meaning, life purpose, life control, suffer acceptance and on the total scale have improved significantly. No gender difference was found on the intervention effect, and participants receiving intervention maintained higher level on related subscales a week later, indicating that supervised movie appreciation is an effective way to improve the life meaning sense among college students.

Residual Fatigue Life Prediction of Ball Bearings Based on Paris Law and RMS

Paris law can reflect the failure mechanism of materials and is usually used to be a method to predict fatigue life or residual fatigue life.But the variable which can represent the health of machine is hardly measured on line.To a degree,the difficulty of on-line application restricts the scope of application of Paris law.The relationship between characteristic values of vibration signals and the variable in the Paris equation which can describe the health of machine is investigated by taking ball bearings as investigative objects.Based on 6205 deep groove ball bearings as a living example,historical lives and vibration signals are analyzed.The feasibility of describing that variable in the Paris equation by the characteristic value of vibration signals is inspected.After that vibration signals decomposed by empirical mode decomposition（EMD）,root mean square（RMS） of intrinsic mode function（IMF） involving fault characteristic frequency has a consistent trend with the diameter of flaws.Based on the trend,two improved Paris models are proposed and the scope of application of them is inspected.These two Paris Models are validated by fatigue residual life data from tests of rolling element bearings and vibration signals monitored in the process of operation of rolling element bearings.It shows that the first improved Paris Model is simple and plain and it can be easily applied in actual conditions.The trend of the fatigue residual life predicted by the second improved Paris model is close to the actual conditions and the result of the prediction is slightly greater than the truth.In conclusion,after the appearance of detectable faults,these improved models based on RMS can predict residual fatigue life on line and a new approach to predict residual fatigue life of ball bearings on line without disturbing the machine running is provided.

Fatigue Life Prediction of Rolling Bearings Based on Modified SWT Mean Stress Correction

The existing engineering empirical life analysis models are not capable of considering the constitutive behavior of materials under contact loads;as a consequence,these methods may not be accurate to predict fatigue lives of roll-ing bearings.In addition,the contact stress of bearing in operation is cyclically pulsating,it also means that the bear-ing undergo non-symmetrical fatigue loadings.Since the mean stress has great effects on fatigue life,in this work,a novel fatigue life prediction model based on the modified SWT mean stress correction is proposed as a basis of which to estimate the fatigue life of rolling bearings,in which,takes sensitivity of materials and mean stress into account.A compensation factor is introduced to overcome the inaccurate predictions resulted from the Smith,Watson,and Topper(SWT)model that considers the mean stress effect and sensitivity while assuming the sensitivity coefficient of all materials to be 0.5.Moreover,the validation of the model is finalized by several practical experimental data and the comparison to the conventional SWT model.The results show the better performance of the proposed model,especially in the accuracy than the existing SWT model.This research will shed light on a new direction for predicting the fatigue life of rolling bearings.

Meaning in life and well-being of older stroke survivors in Chinese communities: Mediating effects of mastery and self-esteem

The study aims to examine the role of mastery and self-esteem as a potential mediator of the relationship of meaning in life and well-being among older Chinese stroke survivors. A cross-sectional study was conducted in 214 community-dwelling older stroke survivors (128 men and 86 women), ranging from 60 years to 88 years old. The meaning in life, mastery, self-esteem and subjective well-being were measured. The results indicated that: 1) The meaning in life and subjective well-being of stroke survivors were significantly positive correlated;2) Mastery and self-esteem played partial mediating roles between existential vacuum and subjective well-being;Self-esteem played full a mediating role between suffer acceptance and subjective well-being;Mastery played a full mediating role between life control and subjective well-being;Mastery played a partial mediating role between death acceptance and subjective well-being;Self-esteem also played a partial mediating role between mastery and subjective well-being.

Effects of Ambient Temperature and Shaft Power Variations on Creep Life Consumption of Industrial Gas Turbine Blades

The effects of ambient temperature and shaft power variations on creep life consumption of compressor turbine blades of LM2500+ industrial gas turbine engine are investigated in this work. An engine model was created in PYTHIA (Cranfield University’s gas turbine software) for the analysis. Blade thermal and stress models were developed and used together with Larson-Miller Parameter method for life analysis. Mean life reduction index, which is the propensity of a given effect to reduce engine life by half, is developed for each effect and applied in this research to compare the impacts of the different effects on the blade creep life. It was observed that blade life will be halved when ambient temperature is increased by 8.11 units while 13.64% increase in shaft power reduces blade life by a factor of 2. The results of this work will guide engine operators in making decisions concerning operating at part loads.

Mindfulness Associates Life Satisfaction:The Mediating Role of Internal Control and the Presence of Meaning in Life

This study explored the internal mechanism of the effect of mindfulness on life satisfaction from the perspective of logotherapy theory and achievement attribution theory.We recruited 1021 college students using a combination of random sampling and cluster sampling.They completed the relevant questionnaire.The results showed that,from the perspective of logotherapy theory,wefind that the presence of meaning in life is an important intermediary between mindfulness and life satisfaction.From the perspective of achievement attribution theory,we found that internal control was an important intermediary between mindfulness and life satisfaction.In addition,we also found the chain mediating path that mindfulness positively predicted life satisfaction by influencing internal control and then influencing the presence of meaning in life.This study proves for thefirst time that the theory of logotherapy and achievement attribution explain the internal mechanism of the relation of mindfulness on life satisfaction.This study provides an important reference for how to effectively improve life satisfaction from the perspective of mindfulness.

Depression by the Theory of Breathing and Finding Meaning of Life

This study aimed to examine the relationship of finding meaning to life with the level of depression and investigates the effect of using breathing theory in treating or reducing depression in a sample of individuals suffering from depression in the Kuwait Mental Health Center.

Meaning in Life and Mental Health Issues in Older Adults:A Meta-Analysis

This study aims to be the first to use meta-analysis to explore the relationship between meaning in life(MIL)and mental health issues among older adults.A meta-analysis was conducted using six databases,resulting in 16 studies with 5,074 participants in total.The“metacor”and“forestplot”packages in R-Studio were used for data analysis.The total effect was calculated using a random-effects model,with I2=86%in the heterogeneity test.The results showed a moderate negative correlation between MIL and mental health issues among older adults,with an average effect of−0.37.Five potential moderating variables were examined:the conceptualization of MIL(value vs.purpose),region(Asian vs.Western countries),residence status(community vs.nursing home vs.hospital),types of mental health issues,and evaluation methods(clinical vs.non-clinical).The first four had no significant moderating effect.The mean correlation coefficients between mental health issues and value/purpose were−0.49/−0.33;the mean correlation coefficients in Asian countries and Western countries were−0.48 and−0.34;the mean correlation coefficients among participants living in community/nursing home/mixed status were−0.33/−0.40/−0.40;the mean correlation coefficients between MIL and depression/others were−0.37/−0.35;however,the negative relationship between MIL and mental health issues was stronger when non-clinical evaluations(self-report only)were used.Specifically,the mean correlation coefficient for non-clinical evaluations was−0.42 and for clinical evaluations was−0.29.This study is the first meta-analysis to identify the negative correlation between older adults’MIL and mental health issues.Significant moderating effects of evaluation methods were found.

Effect of Strain Ratio on Fatigue Model of Ultra-fine Grained Pure Titanium

The ultra-fine grained(UFG)pure titanium was prepared by equal channel angular pressing(ECAP)and rotary swaging(RS).The strain controlled low cycle fatigue(LCF)test was carried out at room temperature.The fatigue life prediction model and mean stress relaxation model under asymmetrical stress load were discussed.The results show that the strain ratio has a significant effect on the low cycle fatigue performance of the UFG pure titanium,and the traditional Manson-coffin model can not accurately predict the fatigue life under asymmetric stress load.Therefore,the SWT mean stress correction model and three-parameter power curve model are proposed,and the test results are verified.The final research shows that the threeparameter power surface model has better representation.By studying the mean stress relaxation phenomenon under the condition of R≠-1,it is revealed that the stress ratio and the strain amplitude are the factors that significantly afiect the mean stress relaxation rate,and the mean stress relaxation model with the two variables is calculated to describe the mean stress relaxation phenomenon of the UFG pure titanium under different strain ratios.The fracture morphology of the samples was observed by SEM,and it was concluded that the final fracture zone of the fatigue fracture of the UFG pure titanium was a mixture of ductile fracture and quasi cleavage fracture.The toughness of the material increases with the increase of strain ratio at the same strain amplitude.

The Ethics and the Meaning of Life among College Students

The concern of the ethics and the meaning of life in young adults became universal and are present in all contexts of human life. Such universality is due to the development of modern rationality, to establish a relationship between the intrinsic theoretical dimensions (scientific) and practical dimensions (ethical), originated that are present in the own array of knowledge. This descriptive cross-sectional study, aims to identify the values of the ethical dimension and meaning of life defended by the college students of the Universities of Madeira, Portugal and Fortaleza, Brazil. The sample consists of 605 University students (Madeira = 225 and Fortaleza = 380), with an average age of 21 years and a standard deviation of 2. We used the questionnaire on values (adapted from the European Values Survey). Most of the young people referred to have a religion (60% wood and 78.4% stronghold), being the most Catholic, however, present in your frequency disinterest and, yet, in Brazil there is a greater diversity of religions. Supporting the intervention of religious institutions in situations of everyday life is accepted mostly by Brazilians, with the exception of politics (35.5%). On the other hand, the university students of the University of Madeira understand that Religious Institutions should only give their opinion on racial discrimination (76.6%). Believe in God (90.8% and 55.1% Stronghold) and Soul (80.3% and 66.4% Stronghold) are beliefs more referred to by college students. These results are intended to contribute in the field of research on ethical values and meaning of life in young people. This study contributes to future comparative research among university students and to developing strategic programs in education and health, increasing the success and excellence in the formation of a full citizenship, preventing the fanaticisms and the social discrimination that today devastate the collective globally.

Time is Not Money!——It Is a Providence of Opportunities

The essay discusses the interrelations between Time and Money and the right ways for managing them.Additionally it discusses other aspects of life and time,such as:definition of time,smart use of time,use of time as distincting between men and animals,time,age and responsibility,time and the“meaning of life”,quality and quantity of lifetime,social aspects of time and science,technology and time.The author clearly expresses his opinion,that Time is a neutral abstract entity,exists in free democratic regimes and in less-liberatated autocracies.It is the explicit responsibility of every man and woman,anywhere,and everywhere,to prepare and train themselves for a smart use of the time awarded to them.On the other hand,Time is available for everyone and everything.The busy diligent hard-working person always seeks more challenging missions,while the less-energetic idle person,is always busy and tire of doing nothing.The author also claims that Time is an opportunity.It is available and inviting every active person,a thinker,a doer,and an entrepreneur to use and have it to achieve their goals.The author advises:Do not complain I have no time-dare to make the first step and“the other will come,tumbling after”.Active individuals have time for every challenging initiative;passive ones have no time for anything.

生命叙事视角下纪录片的主体互动、故事生成与意义流动

纪录片如何以“人”为核心讲述“生命”的故事是其作为一种生命叙事文本的现实关切,也是基于纪录片研究回归人的主体意识与话语建构的理论拓展。纪录片生命叙事中的双重主体,即作为他者化的“自我”的创作者与作为“自我化”的他者的被摄者,呈现出主体间互动的“对话性”。纪录片通过将个体生命经验进行一系列梳理、提取与整合,再与社会的汇流中经由连贯性生产进而形成具有结构性和启发性的生命故事。在纪录片中,生命叙事通过“表现性话语”完成意义的建构,并以反身性认知的形式推动意义的再生产与流动。
