Abstract： Background Cognitive frailty is a prevalent clinical syndrome in the elderly，with subtypes of reversible and potentially reversible cognitive frailty. It is associated with adverse health outcomes such as falls，disability，and mortality. However，there is limited research on the current prevalence of cognitive frailty subtypes and their influencing factors in the elderly population. Objective To investigate the current status of cognitive frailty（CF） among community elderly in Beichen District in Tianjin，and to explore the influencing factors of different subtypes of cognitive frailty，so as to provide references for the early identification and intervention of reversible cognitive frailty（RCF）. Methods From June to August 2023，totally 3 916 community residents in Beichen District，Tianjin were recruited with convenience sampling，and a face-to-face questionnaire survey was conducted using the demography questionnaire，FRAIL Frailty Scale，the Brief Mental Status Examination Scale（MMSE），and the Subjective Cognitive Decline Questionnaire（SCD-Q9） to assess the incidence of different types of cognitive frailty and analyze the influencing factors among older people using a multivariate Logistic regression model. Results Among 3 916 participants，679（17.34%） with RCF and 440（11.24%） with PRCF. There were significantly differences in CF prevalence among the elderly with different genders，ages，educational backgrounds，sleep disorders，the prevalence of various types of chronic illnesses，exercise，smoking histories，drinking histories，the number of medications used for chronic illnesses，and hemoglobin levels（P<0.05）. Multifactorial Logistic regression analysis showed that with no cognitive frailty as a control，being female（OR=2.186，95%CI=1.713-2.791），age ≥ 70 years（OR=3.056，95%CI=2.519-3.708），smoking（OR=1.753，95%CI=1.431-2.146），having a sleep disorder（OR=1.275，95%CI=1.046-1.555），low hemoglobin levels（OR=1.531，95%CI=1.026-2.284），and ≥ 3 medications for a chronic condition（OR=2.168，95%CI=1.490-3.156） were associated with a higher risk of RCF，and exercise（OR=0.459，95%CI=0.382-0.551） was associated with a lower risk of RCF（P<0.05）； being female（OR=1.941，95%CI=1.465-2.573），age ≥ 70 years（OR=1.830，95%CI=1.460-2.292），drinking（OR=2.270，95%CI=1.734-2.970），having a sleep disorder（OR=1.996，95%CI=1.557-2.560），stroke（OR=2.114，95%CI=1.026-4.355），low hemoglobin levels（OR=1.991，95%CI=1.288-3.078） ，and ≥ 3 medications for a chronic condition（OR=1.626，95%CI=1.050-2.518）were associated with a higher risk of PRCF，and exercise（OR=0.522，95%CI=0.423-0.644） was associated with a lower risk of PRCF in the aged（P<0.05）. Conclusion The prevalence of reversible and potentially reversible cognitive frailty is high among the elderly in the community of Beichen District in Tianjin. It is recommended to add the assessment of CF into community physical examinations and implement multidimensional effective strategies to delay the onset and progression of CF.

Abstract： Background With the population ages，the mental health of the elderly has become a hot topic of concern for the whole society. Previous studies have shown that mental health problems in the elderly are closely related to well#2;being，while personality traits have a greater impact on subjective well-being. However，the internal relationship between the two in the elderly population is still unclear. Objective To explore the relationship between subjective well-being and personality traits of the elderly. Methods From July to August 2022，511 elderly people in Lincun，Tangxia Town，Dongguan City， Guangdong Province were selected as the subjects to conduct a site survey by using the questionnaire survey. The subjective well-being and personality traits of the elderly were evaluated by the Memorial University of Newfoundland Scale of Happiness （MUNSH）and the China Big Five Personality Scale（CBF-PI-15）respectively. Pearson correlation analysis was used to analyze the correlation between subjective well-being and personality traits of the elderly，canonical correlation analysis was used to construct a standardized canonical correlation model，canonical structure analysis，and canonical redundancy analysis， to explore the relationship between subjective well-being and the dimensions of personality traits of the elderly. Results The total score of MUNSH in the elderly was（39.72±7.74），and the scores of MUNSH in each dimension werepositive experience （9.48±3.24）， positive emotion（8.61±2.24），negative experience（1.44±2.31），and negative emotion（0.93±1.80） from high to low. The scores of CBF-PI-15 in each dimension of the elderly were agreeableness（14.04±2.60），extroversion （11.77±4.05），conscientiousness（10.75±3.57），openness（7.20±3.90）and neuroticism（6.34±3.22）. Pearson correlation analysis showed that subjective well-being was positively correlated with conscientiousness（r=0.334）and openness （r=0.219）（P<0.05）and negatively correlated with neuroticism（r=-0.223，P<0.05）. Canonical correlation analysis showed that the correlation coefficients of the first and second pairs of canonical correlation variables were 0.476 and 0.331（P<0.001）. The results of the standardized canonical correlation model construction showed that the correlation between the first canonical correlation coefficient of subjective well-being（U1）of the elderly and the first canonical correlation coefficient of personality traits（V1）mainly manifested negative correlation between positive experience and neuroticism，and positive correlation between positive experience and conscientiousness. The correlation between the standardized canonical correlation coefficient of the second canonical variable of subjective well-being（U2）and the standardized canonical correlation coefficient of the second canonical variable of personality traits（V2）of the elderly mainly manifested positive correlation of positive emotion and negative emotion with neuroticism. The results of canonical structure analysis showed that U1 was strongly correlated with positive emotion，negative emotion，positive experience，and negative experience，while U2 was strongly correlated with negative emotion and negative experience. V1 was strongly correlated with positive experience，conscientiousness，and openness. V2 was strongly correlated with neuroticism and openness. Canonical redundancy analysis showed that U1 explained 5.4% variation in personality traits and V1 explained 12.2% variation in subjective well-being，indicating that personality traits had a greater influence on subjective well#2;being than subjective well-being. Conclusion On the whole，the elderly hold a positive and optimistic attitude，with a high level of subjective well-being，which is closely related to neuroticism and conscientious personality. In the future，corresponding intervention strategies should be adopted according to different personality characteristics to improve subjective well-being， maintain the mental health of the elderly，and actively face the aging of population.

Abstract： This study aims to examine the spatiotemporal variation characteristics of grassland vegetation coverat the regional scale and analyze its driving factors. The findings will provide a scientific reference and decisionmakingbasis for the scientific formulation of protection and restoration models, treatment measures, and thesustainable management of the grassland ecosystem in Ningxia, which are crucial for maintaining the balance ofthe regional grassland ecosystem and promoting ecological protection and high- quality development in theYellow River Basin. In this study, the NDVI time series dataset of SPOT/VEGETATION (2000-2019) was usedas the data source. The annual mean method, Theil- Sen Median trend analysis, and Mann- Kendall test wereemployed to study the spatiotemporal distribution and variation characteristics of grassland vegetation cover inNingxia. Furthermore, the Hurst index method was used to analyze the sustainability characteristics and futuredevelopment trends of grassland vegetation cover. Simultaneously, the influence of 13 factors, such as averageprecipitation, altitude, and gross domestic product, on the spatiotemporal distribution was quantified based on thegeographical detectors approach. The results show that from 2000 to 2019, the average annual NDVI ofvegetation in Ningxia grassland showed a fluctuating growth trend, with a growth rate of 0.005 per year. Theregional fluctuation was quite different, with extremely high and high vegetation cover areas concentrated in theLiupan Mountains and the irrigation area along the Yellow River. Overall, the NDVI change showed a low tomedium fluctuation trend, and the regional fluctuation was quite different. The vegetation cover conditionimproved significantly over the 20-year period, with a small degradation area and a favorable overall changetrend. However, 59.341% of the grasslands are projected to face potential risks of continuous degradation ortransformation from improvement to degradation in the future. The most sensitive environmental factorinfluencing grassland vegetation distribution response was precipitation, and climate and soil had the strongestinteraction explanatory power overall. The relationship between the factors affecting the distribution andvariation characteristics of grassland vegetation primarily manifested as mutual reinforcement or nonlinearenhancement, with no independent relationship between the factors. This study provides a scientific reference anddecision-making basis for the sustainable management of the grassland ecosystem in Ningxia.

Abstract： [Purpose/significance] In view of the problem that it's difficult for researchers to find valuable information from large amounts of scientific and technological information in the Web, this paper constructs a comprehensive calculation method for information value. It can calculate the information value of Web technology information and help researchers find Web technology information of information value quickly and accurately.[Method/process] Taking overall consideration of the external feature and textual semantic feature of the information, this paper used deep learning (pretrained language model) BERT to construct information value calculation model based on the textual semantic feature, used the predictive output of the deep learning model to complete the scoring, and combined the original calculation method of the external feature of the information to get the final information value score.[Result/conclusion] The experimental results show that the information value calculation model based on the textual semantic feature can rank the information to different levels according to their information value score, which makes up for the problem of poor star differentiation in the original calculation method only based on the external feature of the information. And the final comprehensive evaluation results show that the information value calculation model proposed in this paper can also meet the needs of researchers in the practical application.

Abstract： Richard Thaler was awarded the 2017 Bank of Sweden Prize in Economic Sciences in Memory of Alfred Nobel for his contributions to behavioral economics. Based on bounded rationality, procrastination, loss aversion, and self-control, Thaler proposed the “Save More Tomorrow” plan that nudge employees to save more for their retirement by increasing the amount saved with every salary raised. Starting at the beginning, Thaler suggested that automatic enrollment can be used as the default option for employees to increase 401(k) participation. At the later stage, automatic escalation, which automatically allocates a fraction of the employees’ future pay increase to 401(k) contribution, is proposed to nudge the increase of contribution rates. The SMarT program, which was labeled as libertarian paternalism, can result in not only increased participation and contribution rates, but also the broad diversification of portfolios. The SMarT program profoundly affected policy in England, New Zealand, and other countries in which governments have established policies to make automatic enrollment the default option for employees to participate in retirement savings plan. Researchers have also been inspired to investigate the mechanism of retirement savings behavior. We first analyze the present status given that the three primary sources of retirement income are disproportionate in China. Then, we discuss and suggest nudge methods to incorporate behavioral economic insights, such as default option, framing effect, mental account and manipulating the “two-route loss” to “one-route loss” to promote retirement savings. Improvements to the participation and contribution rates can also be nudged by designing a plan and formulating a policy on retirement savings in China.

Abstract： The accurate estimation of grassland net primary productivity (NPP) is crucial to understanding the carbon cycle of grassland ecosystems and their adaption to climate change. Based on 1788 grassland biomass data and 19 environmental factors (climate, vegetation, soil, and topographic factors), we simulated the spatiotemporal dynamics of grassland NPP in the Loess Plateau from 2002 to 2020 using the random forest (RF) model. The future trends of grassland NPP under four future climate scenarios of shared socioeconomic pathways were estimated. Results showed that (1) the RF model had a good accuracy, which indicated that RF can be used to estimate grassland NPP in the Loess Plateau; (2) grassland NPP in the Loess Plateau exhibited a“high in southeastern and low in northwestern”pattern, with a mean value of 276.55 g C·m−2·a−1. The highest grassland NPP was observed in Guanzhong Plain of Shaanxi; (3) the grassland NPP in the Loess Plateau showed an overall increasing trend during 2002-2020. Regions experiencing an increase in grassland NPP accounted for 55.01% of the total land area, which is mainly located in Guanzhong Plain, western Gansu, and northern Shanxi; (4) under the wetter and warmer climate, grassland NPP in the Loess Plateau will continually increase by the end of this century. Grassland NPP will increase the most under the SSP585 scenario and the least under the SSP126 scenario. RF can be used to simulate the temporal and spatial trends of grassland NPP in the Loess Plateau. The results provide data support for the protection and sustainable development of grassland ecosystem in the Loess Plateau.

Abstract： The suitable reference genes is a prerequisite for real-time quantitative PCR (RT-qPCR). In order to provide a suitable reference gene for gene expression analysis using RT-qPCR in Euphorbia maculata, the GAPDH, EF-1α, act, UBQ, TUB-α, eIF-4A, and CYP gene fragments were cloned with the method of homologous cloning. Subsequently, the expression patterns of the seven candidate reference genes were obtained by RT-qPCR in E. maculata, and the expression stability was assessed by geNorm, NormFinder, and BestKeeper. The results suggested that the fragment sequences of GAPDH, EF-1α, act, UBQ, TUB-α, eIF-4A and CYP contained 729 bp (encoding 242 amino acids), 808 bp (encoding 269 amino acids), 753 bp (encoding 250 amino acids), 422 bp (encoding 140 amino acids), 233 bp (encoding 77 amino acids), 656 bp (encoding 218 amino acids), and 313 bp (encoding 103 amino acids), respectively. And the seven amino acid sequences shared over 85% identity with other GAPDH, EF-1α, act, UBQ, TUB-α, eIF-4A, CYP by Blastp in GenBank. On the other hand, the order of expression stability was UBQ>EF-1α>TUB-α>eIF-4A>GAPDH>CYP>act by GeNorm, NormFinder, and BestKeeper. Therefore, UBQ could be selected as a reference gene for RT-qPCR in E. maculata using for gene expression analysis in various plant tissues at different growth stages.

Abstract：在生活中，我们时常会选取或接受一个导致明显损失的选项（如，无酬加班）。主流决策理论不会将此选择预测或解释为我们主动做出的行为选择，反倒是中国古语“吃亏是福”这一信条不仅对此进行了阐释，而且还大力推崇这类行为。为了探索“吃亏是福”信条起作用的机制，我们自创了一个基于成功人士吃亏轶事的量表，用于测量“吃亏似然性”。考虑到“福”可分为“主观”与“客观”之福；“报”可分为“现报”与“后报”，我们发现（1）当下吃亏似然性分数越高的人，当下拥有的社会经济地位指数（SEI）越高、主观幸福感（SWB）越强；（2）真金白银的当前社会经济地位指数（SEI）既可以被当下的吃亏似然性所预测，也可以被想象的多年前吃亏似然性所预测（即以前吃的亏能预测现在受的福），且想象以前吃亏的年代越久远，预测的效果越佳。我们的发现提示“吃亏是福”不是传说而是现实。

Abstract：理解并有效评估我国的城镇化建设对推进我国长期可持续发展至关重要。然而，人们对城镇化的评估结果却似乎与其所采用的评估方法（客观指标或主观指标）有关。通过对以往研究的综述，该研究发现，尽管评估地区的客观指标（如，文盲率）随着城镇化程度的升高而阶梯状改善，但是民众的主观指标却并没有随着中国城镇化水平的提高而上升。城市居民和农村居民在住地依恋的得分上大致相当，而原本预期得分介于两者之间的城镇居民则在住地依恋的得分上最低，该研究称这一“V形”现象为“城镇位错效应”。进一步的文献综述与调查分析显示，民众的住地依恋主要受到人口统计学指标、人际关系与物理环境的影响。建议在城镇化的评估中，结合使用客观指标与主观指标。
