Low-carbon economy is an emerging and inevitable pathway toward sustainable development of cold chain logistics. Low-temperature transportation is the crucial link of cold chain logistics to low-carbon economy and the industry is known to have the higher energy consumption. Prior studies are lacking in involving the carbon emission cost in the optimization process. Route optimization of low-temperature transportation is conducive to the low-carbon cold chain logistics. This study aims to introduce the low-carbon economy into the cold chain logistics. There are various costs needed to be considered in cold chain logistics, and a cold chain logistics route optimization model included the carbon emission cost was developed. Ribonucleic acid computing was combined with ant colony optimization to prevent the influence of unreasonable parameter selection on algorithm performance. This novel proposed approach was applied to solve the route optimization problem of a cold chain logistics firm located in the Xiong'an, China. The results showed this method reduced the overall cost of logistics and minimized the amount of carbon emissions. The finding shed the light on the low-carbon transformational development of cold chain logistics firms. • Low-carbon economy moves toward sustainable development of cold chain logistics. • Low-temperature transportation links cold chain logistics to low-carbon economy. • The ribonucleic acid (RNA) and the ant colony optimization (ACO) are combined. • RNA–ACO offers a better solution to the route optimization of cold chain logistics.

This study aimed to develop a Chinese Mental Resilience Scale. A total of 2500 healthy participants, in two representative samples of the Chinese population, were administered the scale. Exploratory factor analysis, confirmatory factor analysis, and correlation analysis were used to obtain the relevant coefficients and verify the reliability and validity of the scale. Five factors were extracted: willpower, family support, optimism and self-confidence, problem solving, and interpersonal interaction, plus a lying subscale, which together accounted for 54 percent of the total variance. The Chinese Mental Resilience Scale demonstrated good psychometric properties. It can be used to evaluate the mental resilience level of general Chinese population. [ABSTRACT FROM AUTHOR]

Background: A devastating earthquake registering 8.0 on the Richter Scale struck Wenchuan County in Northwest Sichuan Province in China on May 12, 2008, claiming over 69,200 lives, seriously wounding more than 374,600 people, and rendering more than 18,400 people missing. The epicenter was close to Yingxiu Township in Wenchuan County. Purpose: This study aimed to investigate the psychosomatic conditions of the children and adolescents exposed to the devastating earthquake and explore the risk factors for psychosomatic symptoms. Method: A total of 1,828 participants aged 6 to 16 years, of whom 842 from the affected area and 986 from non-affected area, were administered a Psychosomatic Conditions Scale. Results: Each factor score, total somatic score, total psychological score, and total psychosomatic score of the experimental group were significantly higher than those of the control group ( P < 0.001). Positive correlation was found between the psychological state and somatic symptoms in the experimental group( r = 0.157 ~ 0.489, P < 0.01). Respiratory system, cardiovascular system, nervous system, digestive system, urogenital system, emotion, behavior, and language, combined as a panel, were significantly differentiated between the two groups, accounting for 73.4 % of the total difference. In the experimental group, the factor scores of anxiety, behavior, total psychological score, and total psychosomatic score of the girls were obviously higher than those of the boys ( P < 0.01 ~ 0.05); most somatic factors and psychological factors, total somatic score, total psychological score, and total psychosomatic score of the elder adolescents were significantly higher than those of the younger children ( P < 0.01 ~ 0.05). Conclusion: The children and adolescents exposed to 5.12 earthquake greatly suffered from terrible psychosomatic conditions, among whom the elder girls had more severe symptoms, particularly in terms of anxiety and behavior.

Judicial Interpretation about Travel Disputes" comes up with the concept of "travel auxiliary servants" for the first time. Comparing to the concept of implementing the aid-party in comparative law, its meaning is greatly limited. On the one hand, travel auxiliary servants are required to have contracts with travel operators and on the other hand, the provider of public transportation is excluded. For the instance of providing defective performances that bring up damage to tourists' rights by travel auxiliary servants, rights and obligations between the three are thus complex. Travel operators should bear the liability for the breach of contract for travelers, travel auxiliary servants should bear liability in tort for travelers and travel auxiliary servants should bear the liability for the breach of contract for travel operators. Due to the right to recover holding by travel operators, travel auxiliary servants usually undertake the final responsibility. Therefore, travel operators and travel auxiliary servants shoulder the untrue joint and several liability for travelers and travelers can only bring a lawsuit to one party. [ABSTRACT FROM AUTHOR]

This study aimed to investigate the effects of sleep deprivation on serum cortisol level and mental health and explore the correlations between them in servicemen. A total of 149 out of the 207 Chinese servicemen were randomly selected to go through 24hour sleep deprivation, leaving the rest (58) as the control group, before and after which their blood samples were drawn for cortisol measurement. Following the procedure, all the participants were administered the Military Personnel Mental Disorder Prediction Scale, taking the military norm as baseline. The results revealed that the post-deprivation serum cortisol level was positively correlated with the factor score of mania in the sleep deprivation group (rSp=0.415, p<0.001). Sleep deprivation could significantly increase serum cortisol level and may affect mental health in servicemen. The increase of serum cortisol level is significantly related to mania disorder during sleep deprivation., (Copyright © 2015 Elsevier B.V. All rights reserved.)

Objective: The primary aim of the present study was to quantitatively assess and analyze influential psychosocial factors in the mental health of new military recruits., Methods: A total of 2,734 army recruits were evaluated by using the Symptom Checklist-90 (SCL-90) and Trait Meta-Mood Scale., Results: In general, the army recruits were found to be in a good state of mental health. The SCL-90 scores of the new recruits were significantly higher than those of the normal civilian population (p < 0.01). The new recruits were similar to the normal army population, with notable exceptions in the following three scales: obsessive-compulsive, depression, and anxiety (p < 0.01 or p < 0.05). Factors that significantly influenced the SCL-90 scores included childhood environment, education level, and parental relationship. Results from the current study also revealed negative associations between the SCL-90 global severity index and the Trait Meta-Mood Scale subscale scores (p < 0.01)., Conclusion: The mental health status of army recruits is closely related to their childhood environment, education level, parental relationship, and emotional intelligence. These factors should be considered by mental health workers, to help new army recruits adapt to the new environment.
