Background:In today’s society,parental stress has become a prevalent and significant issue,impacting not only parents’mental health but also potentially profoundly affecting children’s growth and education.This topic has garnered continuous attention from scholars.The present study aims to delve into the relationship between parental stress and children’s behavior,particularly focusing on children’s conformity and discipline development during crucial stages.This study aims to explore the relationship between parental stress,child conformity,and resilience,and further examines the mediating role of resilience in the relationship between parental stress and child conformity.Methods:We used three scales:the Parental Stress Scale,the Child Conformity Scale,and the Resilience Scale,to survey 890 elementary school students(aged 6–12)and their parents in the Beijing-Tianjin-Hebei region of China.We employed SPSS 26.0 software for data analysis,conducting descriptive statistics,correlation analysis,and mediation effect tests sequentially.In the mediation effect tests,we utilized structural equation modeling(SEM)and regression analysis to examine the mediation effects,ensuring the accuracy and scientific nature of our analysis.Results:Through descriptive statistics,correlation analysis,regression models,and mediation effect tests,we found that parental stress significantly negatively predicts child conformity,while resilience shows a significant positive prediction.Further mediation analysis indicates that resilience plays a partial mediating role between parental stress and child conformity,with the mediation effect accounting for 36.67%.Conclusion:These findings highlight the importance of the family environment on child behavior and provide valuable insights and recommendations for family education practices in the Beijing-Tianjin-Hebei region.Therefore,we suggest future research should further explore the complex relationships among parental stress,child conformity,and resilience,and examine regional differences to better promote children’s overall development. 展开更多

This paper argues that the conformity-nonconformity dichotomy is a false dilemma.This study first critically reviews the basic philosophical,ethical,social psychological,and pedagogical literature related to the two concepts.It then outlines the way to overcome the phenomena of conformism and nonconformism together.The description of conformity and nonconformity as deprivation of freedom becomes stronger in 20th century philosophy and special literature from Heidegger through Fischer’s definition up to Cooley,and Crutchfield.Conformity is the sinking of the Self into the Anyone,the unprincipled alignment to the opinion of group mates,and nonconformity is the unprincipled resistance to it.But what is beyond conformity and nonconformity together as a group?There is a real community,in it the transformation of our pedagogical culture in a both useful and reasonable manner to allow the youth to accept the world by denying it and to deny the world by accepting it.The real community involves the virtue of goodness.Educate for goodness,because we possibly are the honest and humane man,who disregards the sinking of the self into the anyone and the self-contained rebellion. 展开更多

Individual decision-making processes are not solely driven by self-interest maximization but are also influenced by the pressure to conform to the group.In primary games like the prisoner's dilemma,the presence of conformity pressure may facilitate the constructive development of cooperative behavior.In this study,we investigate how conformity influences the growth of cooperation in complicated coordination games.Our findings reveal that,even in the presence of stringent game rules,conformity can promote cooperation.In fact,a certain level of conformity pressure can even eliminate the“defection basin”of deer hunting games played on regular networks.Additionally,we demonstrate that the effect of conformity on cooperative behavior is contingent upon the degree of conformity pressure,with different levels of conformity pressure producing opposite effects.These findings provide novel insights into the promotion of cooperative evolution.For instance,if increasing the reward for cooperation has proven ineffective,manipulating the proportion of initial strategy choices may be a more promising approach. 展开更多

This paper has developed a single mathematical measure for the evaluation of the shape conformity of the curved garment objects such as moulded brassiere cups. The measurements are based on the sectional analysis of the fringe pattern generated by means of moire topography. They include the area ratio, shape ratio and root mean square (RMS) of the height deviation of the moulded cup from the standard shape profile. Ultimately, the RMS was found to be a satisfactory method of assessing the shape conformity and a guideline for determining a good fit from the RMS value was then derived. 展开更多

Background: Studies have shown that there are striking variations in knee morphology between Asian and Western population. However, most of the existing total knee arthroplasty (TKA) implants are designed to suit the anatomy of Western population. Our study investigated anthropometry of Indian arthritic knees and compared them to international ethnic groups. Methods: Computed tomography was used to create 3D knee models and obtain anthropometric data of distal femur and proximal tibia of Indian arthritic knees. Femoral measurements included mediolateral length, medial and lateral anteroposterior length, medial and lateral condylar width and aspect ratio. Tibial measurements included mediolateral length, medial, lateral and central anteroposterior length and aspect ratio. A preoperative virtual implantation using Western TKAimplants was carried out to visualize anatomical conformity. Results: Statistical analysis results showed that Indian males had significantly larger femoral and tibial mediolateral and anteroposterior width than Indian females;however, femoral and tibial aspect ratio was similar for both. In case of females, significant difference was observed between medial and lateral condylar widths. When compared to knee anthropometry of other ethnic groups, femoral and tibial aspect ratio of Indian knees was found to be similar to the Asian population and different from the Western population. The virtual implantation showed overhang of the femoral component in both lateral and medial regions. Conclusion: Morphological mismatch between Western and Indian knees established the fact that Western implants have drawbacks when implanted in Indian patients. The study also provided a basis for designing gender-specific TKA implants for the Indian population. 展开更多

This paper presents an approach for extending the constraint model defined for conformity testing of a given method of class to its overriding method in subclass using inheritance principle. The first objective of the proposed work is to find the relationship between the test model of an overriding method and its overridden method using the constraint propagation. In this context the approach shows that the test cases developed for testing an original method can be used for testing its overriding method in a subclass and then the number of test cases can be reduced considerably. The second objective is the use of invalid data which do not satisfy the precondition constraint and induce valid output values for introducing a new concept of test called secure testing. The implementation of this approach is based on a random generation of test data and analysis by formal proof. 展开更多

From birth to adulthood,we often align our behaviors,attitudes,and opinions with a majority,a phenomenon known as social conformity.A seminal framework has proposed that conformity behaviors are mainly driven by three fundamental motives:a desire to gain more information to be accurate,to obtain social approval from others,and to maintain a favorable self-concept.Despite extensive interest in neuroimaging investigation of social conformity,the relationship between brain systems and these fundamental motivations has yet to be established.Here,we reviewed brain imaging findings of social conformity with a componential framework,aiming to reveal the neuropsychological substrates underlying different conformity motivations.First,information-seeking engages the evaluation of social information,information integration,and modification of task-related activity,corresponding to brain networks implicated in reward,cognitive control,and tasks at hand.Second,social acceptance involves the anticipation of social acceptance or rejection and mental state attribution,mediated by networks of reward,punishment,and mentalizing.Third,self-enhancement entails the excessive representation of positive self-related information and suppression of negative self-related information,ingroup favoritism and/or outgroup derogation,and elaborated mentalizing processes to the ingroup,supported by brain systems of reward,punishment,and mentalizing.Therefore,recent brain imaging studies have provided important insights into the fundamental motivations of social conformity in terms of component processes and brain mechanisms. 展开更多

The New Curriculum Standard(NCS)is the norm and quality requirement of the Chinese national educational curriculum as well as the basis of teaching management,curriculum evaluation,and textbook compilation.In textbook design,the selection of textbook materials should meet the objectives and requirements of the NCS.Since appropriate teaching materials are essential to curriculum standards and effective teaching,we must follow the consistency between textbook materials and curriculum standards to achieve an ideal degree of conformity with the textbook system and teaching objectives and promote the sustainable development of the English curriculum reform.However,the current primary school English textbooks fall short of the NCS,which leads to difficulties in implementing teaching tasks and achieving teaching goals.Given these difficulties,we should analyze the causes from three dimensions:linguistic knowledge,cultural awareness,and learning strategies.In addition,a high recurrence of phonetic knowledge,systematic grammar presentation,diversified learning styles,level grading,and in-depth involvement of cultural factors are keys to the perfect conformity of the NCS and English textbooks. 展开更多

A popular explicit analytic Borowy 2C PV module model is proposed for power generation prediction.The maximum power point and the open-circuit point which are calculated in this model cannot be equal to the data given by manufacturers under standard test condition(STC).The derivation of this model has never been mentioned in any literatures.The parameter forms of 2C model in this paper are more simplified,and the model is decomposed into a STC sub-model and an incremental sub-model.The STC model is derived successfully from an ideal single-diode circuit model.Relative error estimations are developed to do the conformity error measurements.The analysis results showed that though the biases at those critical points are very small,the conformity will depend on both of the two ratio values I_(m)/I_(sc) and V_(m)/V_(oc),which can be used to verify whether 2C model is applicable for the PV module produced by a particular manufacturer. 展开更多

Electromagnetic interference shielding(EMI SE)modules are the core com-ponent of modern electronics.However,the tra-ditional metal-based SE modules always take up indispensable three-dimensional space inside electronics,posing a major obstacle to the integra-tion of electronics.The innovation of integrating 3D-printed conformal shielding(c-SE)modules with packaging materials onto core electronics offers infinite possibilities to satisfy ideal SE func-tion without occupying additional space.Herein,the 3D printable carbon-based inks with various proportions of graphene and carbon nanotube nanoparticles are well-formulated by manipulating their rheological peculiarity.Accordingly,the free-constructed architectures with arbitrarily-customized structure and multifunctionality are created via 3D printing.In particular,the SE performance of 3D-printed frame is up to 61.4 dB,simultaneously accompanied with an ultralight architecture of 0.076 g cm^(-3) and a superhigh specific shielding of 802.4 dB cm3 g^(-1).Moreover,as a proof-of-concept,the 3D-printed c-SE module is in situ integrated into core electronics,successfully replacing the traditional metal-based module to afford multiple functions for electromagnetic compatibility and thermal dissipa-tion.Thus,this scientific innovation completely makes up the blank for assembling carbon-based c-SE modules and sheds a brilliant light on developing the next generation of high-performance shielding materials with arbitrarily-customized structure for integrated electronics. 展开更多

The application of thermoelectric devices(TEDs)for personalized thermoregulation is attractive for saving energy while balancing the quality of life.TEDs that directly attach to human skin remarkably minimized the energy wasted for cooling the entire environment.However,facing the extreme dynamic geometry change and strain of human skin,conventional TEDs cannot align with the contour of our bodies for the best thermoregulation effect.Hence,we designed a kirigami-based wearable TED with excellent water vapor permeability,flexibility,and conformability.Numerical analysis and experimental results reveal that our product can withstand various types of large mechanical deformation without circuit rupture.The stated outcome and proposed facile approach not only reinforce the development of wearable TEDs but also offer an innovative opportunity for different electronics that require high conformability. 展开更多

Implantable hydrogel-based bioelectronics(IHB)can precisely monitor human health and diagnose diseases.However,achieving biodegradability,biocompatibility,and high conformality with soft tissues poses significant challenges for IHB.Gelatin is the most suitable candidate for IHB since it is a collagen hydrolysate and a substantial part of the extracellular matrix found naturally in most tissues.This study used 3D printing ultrafine fiber networks with metamaterial design to embed into ultra-low elastic modulus hydrogel to create a novel gelatin-based conductive film(GCF)with mechanical programmability.The regulation of GCF nearly covers soft tissue mechanics,an elastic modulus from 20 to 420 kPa,and a Poisson’s ratio from-0.25 to 0.52.The negative Poisson’s ratio promotes conformality with soft tissues to improve the efficiency of biological interfaces.The GCF can monitor heartbeat signals and respiratory rate by determining cardiac deformation due to its high conformability.Notably,the gelatin characteristics of the biodegradable GCF enable the sensor to monitor and support tissue restoration.The GCF metamaterial design offers a unique idea for bioelectronics to develop implantable sensors that integrate monitoring and tissue repair and a customized method for endowing implanted sensors to be highly conformal with soft tissues. 展开更多
