    Subjects: Medicine, Pharmacy >> Clinical Medicine submitted time 2024-03-11 Cooperative journals: 《中国全科医学》

    Abstract: Background Microalbuminuria is a sensitive indicator of early renal microvascular damage and an independent risk factor for cardiovascular diseases. Previous studies have shown that long-term chronic inflammation plays an important role in the occurrence and development of microalbuminuria. However,the correlation between blood inflammatory markers and microalbuminuria has been less frequently reported. Objective To investigate the correlation between systemic immune inflammatory index(SII)and systemic inflammatory response index(SIRI)and microalbuminuria in a middle-aged and elderly physical examination population. Methods This was a cross-sectional study in which 2,105 medical examiners over the age of 40 years who underwent health check-ups from April to July 2023 at the Department of Health Medicine,General Hospital of the Eastern Theatre of Operations were selected as study subjects. The study subjects were divided into two groups based on the urinary microalbumin/urinary creatinine ratio(UACR)values:the non-microalbuminuric group(1 857 cases, UACR<30 mg/g)and the microalbuminuric group(248 cases,UACR=30-300 mg/g). SII was divided into T1(0.09-0.27), T2(0.28-0.40)and T3(0.41-1.38)according to tertile grouping,and SIRI was divided into t1(0.11-0.41),t2(0.42-0.66) and t3(0.67-3.52). The general information and laboratory test results of the two study groups were collected and compared, and linear regression analysis was used to explore the correlation between the levels of SII and SIRI and the log-transformed value of UACR(log UACR),and multifactorial logistic regression analysis was used to explore the correlation between the levels of SII and SIRI and the risk of microalbuminuria. Results Comparison of gender,waist-to-hip ratio,total cholesterol,low density lipoprotein cholesterol,and uric acid levels between the two groups showed no statistically significant difference(P>0.05); age,BMI,systolic blood pressure,diastolic blood pressure,fasting blood glucose,2 h blood glucose,glycosylated hemoglobin,triglycerides,homocysteine,glomerular filtration rate erythrocyte sedimentation rate,SII,and SIRI levels were higher in the microalbuminuria group than those in the non-microalbuminuria group,and high density lipoprotein cholesterol level was lower than that in the non-microalbuminuria group(P<0.05). Linear regression analysis showed that the levels of SII and SIRI were positively correlated with log UACR(P<0.05). The results of binary Logistic regression analysis showed that, after correcting for each control variable,the level of SII was positively correlated with the risk of microalbuminuria(OR=1.17, 95%CI=1.01-1.35,P=0.031),and T3 was positively correlated with the risk of microalbuminuria when compared to T1(OR=1.43, 95%CI=1.01-2.03,P=0.046),and the risk of microalbuminuria tended to increase with increasing SII(P 趋势 =0.038). After correcting for each control variable,the level of SIRI was positively correlated with the risk of microalbuminuria(OR=1.18,95%CI=1.03-1.35,P=0.019);t3 was positively correlated with the risk of microalbuminuria compared to t1(OR=1.45,95%CI=1.01~2.09,P=0.046)and the risk tended to increase with increasing SIRI(P 趋势 =0.032). Conclusion SII and SIRI levels correlated positively with both log UACRand risk of microalbuminuria in middle-aged and elderly subjects who received health examination.

    Subjects: Psychology >> Medical Psychology submitted time 2024-01-18

    Abstract: Social interaction impairment is one of the core symptoms of children with Autistic Spectrum Disorders (ASD) which requires early intervention for successful social skills. The conventional approaches of psychological rehabilitation have many limitations such as time consuming, high cost, and shortage of professional rehabilitation therapists. With the development of artificial intelligence, social robots with their unique strengths are widely used in improving social interactions of children with ASD. This paper discusses the potential of social robots in the treatment of autism spectrum disorder and the current applications of social robots for the therapeutic treatment of joint attention, self-initiations, motor imitation, and other social function in ASD patients. It also analyzes the strengths and weaknesses of social robots during the intervention in terms of experimental environments and methods among other factors. It is proposed that future research can be conducted to develop new social scenarios based on the characteristics of human-robot interaction; combine multimodality and brain science and technology to reveal the psychological process of human-robot interaction; construct closed-loop systems for social robots by leveraging the advancing artificial intelligence technology.
     

  • Revisiting family motivation from the actor versus observer perspectives

    Subjects: Other Disciplines >> Synthetic discipline submitted time 2023-10-09 Cooperative journals: 《心理科学进展》

    Abstract: Family motivation describes the desire to expend effort to support one’s family. After its proposal, the construct of family motivation has promoted the progress of work motivation research and provided a new perspective for insights into employees' work behaviors. Existing research mainly emphasizes the prosocial nature of family motivation, while largely ignored its work motivation nature. Although some scholars have indicated that family motivation is a special type of extrinsic work motivation, their research has limitations in scope because of their narrow focus on employees with more controlled forms of family motivation under high family financial pressure. In fact, individuals could experience more autonomous forms of family motivation when they identify with the responsibility of raising the family or even integrate it into their own value system. In other words, individuals with the same level of family motivation might internalize their family motivation in different degrees due to their varied reasons for working to benefit their family. Therefore, based on the self-determination theory, this study defines family motivation as a special extrinsic work motivation and proposes that it has two key dimensions independent of each other. One is the extent to which an individual desires to benefit the family (i.e., level of family motivation), and the other is the extent to which the individual internalizes the goal of working for the family (i.e., internalization of family motivation). Based on this definition, this study adopts both the actor and observer perspectives to explore whether and how family motivation affects employees' organizational citizenship behaviors and the subsequent interpersonal impacts on employees. From the actor perspective, this study consults the conservation of resources theory to propose that employees with high levels of family motivation may have a stronger desire to protect and obtain more resources in the organization. As a result, they would be motivated to proactively engage in more organizational citizenship behaviors to gain additional resources. This effect would further depend on one’s internalization of family motivation. Specifically, employee who internalize their family motivation to a lesser degree (i.e., with more controlled forms of family motivation) tend to place a higher value on the resources at work and thus have a stronger motivation to engage in organizational citizenship behaviors to obtain more resources. Based on the perspective of observers, the first aim of this study is to explore observers’ (i.e., interviewers’) overall perceptions of applicants who disclose their family motivation in job interviews. Then, this research investigates how observers (i.e., leaders) attribute and react to organizational citizenship behaviors performed by employees with varied family motivation. Importantly, leaders’ perceived level of the actor’s family motivation and perceived internalization of the actor’s family motivation are both expected to play moderating roles in the attribution process. Taken together, taking both the actor and observer perspectives, this study not only clarifies the work motivation nature of family motivation but also contributes to understanding of the potential long-term impacts of family motivation on employees from an interpersonal interaction perspective, which expands the boundaries of research on family motivation to a great extent. This research also bears fundamental practical implications. Managers are encouraged to better understand how the level and internalization of family motivation would affect employees’ work behaviors, and then determine proper recruitment standards. In addition, this research enlightens employees who desire to work hard to benefit their family to realize how pivotal observers at work, such as interviewers and leaders, attribute and react to their extra-role behaviors, which helps determine whether they should disclose family motivation in the workplace.

  • Research on Evolution of Yellow River Basin Innovation Network and Cultivation of Zhengzhou-Luoyang-Xi’an Innovation Corridor

    Subjects: Other Disciplines >> Synthetic discipline submitted time 2023-03-28 Cooperative journals: 《中国科学院院刊》

    Abstract: Constructing innovation networks and cultivating innovation corridors are important to realize regional innovation development. Based on the data of patent transfer from 1987 to 2018, this paper analyzes the spatial-temporal evolution of technology transfer network at different scales in the Yellow River Basin, and proposes the cultivation path of Zhengzhou-Luoyang-Xi’an innovation corridor. Firstly, it is found that a majority of technology transfer within the basin is switching from inter-provincial transfer to intra-provincial transfer, with provincial capitals being the main source of technology. Xi’an is the primary source of technology transfer network, and cities, such as Zhengzhou, Qingdao, and Jinan, are secondary sources. Moreover, the technology sources outside the Yellow River Basin are mainly located in the Beijing-Tianjin-Hebei, Yangtze River Delta, Pearl River Delta and other developed urban agglomerations. In addition, Xi’an, Jinan, Qingdao and other high-level central cities have become the main receiving areas of technology transfer. This study concludes that the construction of inter-provincial innovation network should focus on the construction of Zhengzhou-Luoyang-Xi’an innovation corridor, in order to realize the matching and coordination of industrial technological advantages and technological demands of different cities, promote the construction of Zhengzhou-Luoyang-Xi’an high-quality development cooperation belt, and then accelerate the innovation-driven development process of the Yellow River Basin.

  • 中国儿童青少年跨期决策的发展与脑发育机制

    Subjects: Psychology >> Developmental Psychology submitted time 2023-03-28 Cooperative journals: 《心理科学进展》

    Abstract: Intertemporal decision-making refers to the phenomena that people always give less weight to future gains and losses than recent gains and losses. Although controversial, Mischel and colleagues had demonstrated that children with higher delay gratification ability had higher academic achievement later in life through the famous “Marshmallow Experiment”. Both delay gratification and inter-temporal choice deal with the decision-making behavior over time. Previous studies had discovered three neural network systems that support intertemporal decision making in the adult brain, but few evidences had been reported in children. These brain network systems were mainly located in the frontal cortex, which developed rapidly in children and adolescents. The current study aimed to provide a comprehensive survey for understanding the dynamic development of inter-temporal decision-making in children and adolescents in mainland China within the critical period of the inter-temporal decision-making by cross-sectional and longitudinal designs. Neuroimaging data will also be collected to examine the relationship between intertemporal decision-making development and brain mutation, with a special focus on the prefrontal-striatum neural network. Finally, a model with multimodal neuroimaging and behavioral fusion would be proposed to predict the inter-temporal decision-making ability. These evidences would provide services for parents, schools, as well as the society to cultivate and improve the intertemporal decision-making ability in children and adolescents.

  • 学龄前儿童社会善念理解的发展与心理理论的关系

    Subjects: Psychology >> Social Psychology submitted time 2023-03-27 Cooperative journals: 《心理学报》

    Abstract: We live in a highly interdependent world. Even if we do not directly interact with others, our own behaviors can have an indirect impact on others. Such behaviors that indirectly bring benefits to others are defined as considerate, socially-mindful actions. In this study, we examined preschoolers’ evaluation of considerate socially-mindful actions; importantly, we also explored the underlying developmental mechanisms by examining its potential relationship to the development of theory-of-mind abilities. A total of 100 children aged 4~6 were recruited in this study. In the social mindfulness task, children were asked to compare two story characters, both of whom were to choose snack at snack time. One of the characters leaves a choice for the person waiting behind when she took a piece of fruit for herself (i.e., acts socially mindful), while the other character in a similar situation leaves no choice for the person waiting behind (i.e., does not act socially mindful). Children were then asked 1) which of these two characters was nicer and 2) who they would prefer to choose as a friend. In addition, children were also administered theory-of-mind tasks (including the content false belief task, location false belief task, and hidden emotion task). We also measured children’s prosocial orientation (by a sharing task) and executive functioning capacity (by a Day/Night Stroop task) as controlling variables. We found that, first, with age, children increasingly rated the socially-mindful character as nicer than the character who left no choice, and increasingly selected the socially-mindful character as a friend. Second, when controlling for age, children's evaluations and friend preference in the social mindfulness task was significantly positively correlated with their theory-of-mind, but was not correlated with their sharing behaviors or executive functioning. Such correlation remained significant when controlling for sharing and executive functioning. In summary, between the ages 4 and 6, children gradually develop an understanding and evaluation of social mindfulness, and such development is correlated with the development of theory-of-mind abilities. These findings provide insights for our understanding of children's social and moral evaluation and its underlying developmental mechanism.

    The construct of family motivation has promoted the progress of work motivation research to a large extent and provided a new perspective for insights into employees’ work behaviors. However, existing research mainly focuses on the prosocial nature of family motivation, while ignored its work motivation nature. Therefore, from a work motivation perspective, this study proposes that family motivation has two independent dimensions (i.e., level and internalization) and focuses on the effect of family motivation on organizational citizenship behaviors (OCBs) and its subsequent interpersonal influences. This study first examines how family motivation predicts employees’ OCBs from the actor perspective, and then explores observers’ (i.e., interviewers’) overall perception of applicants with varied family motivation in job interviews and how observers (i.e., leaders) attribute and react to OCBs performed by employees with varied family motivation from the observer perspective. Taking both the actor and observer perspectives, this research attempts to gain a comprehensive insight into the work motivation nature of family motivation, its impact on employees’ extra-role work behaviors and to provide guidance for managerial practices.

    Abstract: The existing evaluation methods for node importance in complex network mainly focus on un-directed and un-weighed networks, and can’t describe the real-world network completely. For example, most centrality measures only consider a single indicator, ignoring the difference between out-degree and in-degree of the node, and neglecting the importance of weight. Based on the directed-weighted complex network, this paper proposes a center node recognition algorithm, cw-shell decomposition method, which is based on out-degree, in-degree and weight, considering the difference between out-degree and in-degree of the node, and the practical importance of weight in real network. In order to verify the effectiveness of the new index, the weighted-susceptible-infectious-recovered model is used to simulate spreading process on real-world networks. The results show that the cw-shell decomposition method can rank the nodes efficiently, and identify the nodes with higher diffusion ability.

    Abstract: [Objective] This study aims to identify the key nodes of public opinion spread and evolution based on the semantic social network model. [Methods] We first built model for Weibo semantic social network with the help of hypernetwork theory, and then used emotion Ontology and LDA model to quantify nodes. Finally, we established the hyper edge sorting algorithm to identify the key nodes. [Results] The proposed model could effectively and acturately quantify those nodes from real Weibo data. [Limitations] We did not explore the results of the proposed method’s real-time performance, and new ways of leading the public opinion after identifying those key nodes. [Conclusions]This study provides a solution for the government to identify the key nodes in the social network systems, and then reduce the impacts of negative contents to the healthy development of the Internet.
