Hilary Putnam made the claim several times that the direct reference theory (DRT) he endorsed had startling consequences for the theory of necessary truth and essentialism. If DRT was correct, so he claimed, it followed that things belonging to natural kinds had their deep structures necessarily. Inspired by Keith Donnellan, Nathan Salmon tried to spell out what Putnam seemed to have in mind when making the claim, and Salmon called the result of his analysis “the OK mechanism.” Salmon showed that (...) it was not DRT, but some other essentialism-entailing premise, that had the claimed startling consequences in the OK mechanism. In this paper, I argue that Salmon’s OK is not the right interpretation of Putnam’s intended mechanism. Instead, I present Putnam’s intention as the OK* mechanism, and show that, in OK*, DRT does have the claimed startling consequences when supplemented only with other metaphysically innocent, purely empirically verifiable premises.

The Iowa Gambling Task (IGT) simulates uncertain gains and losses in real life situations and thus is a good measure of uncertain decision making. The role of working memory (WM) in IGT performance still remains unclear. The present study aimed to examine the effect of WM on IGT performance. Three groups of participants matched on gender ratio were randomly assigned to no WM load, low WM load, and high WM load conditions. Initially the three groups did not show significant difference (...) in WM capacity. They finished a modified version of IGT and then their implicit learning effect and explicit cognition on IGT were assessed. Results indicated a linear increasing trend of IGT performance among high WM load, low WM load and no WM load groups; participants in the no WM load and low WM load groups revealed implicit learning effect, while participants in the high WM load group did not; all participants showed explicit cognition on IGT to the same level. These results suggested that participants in the high WM load group showed good explicit cognition to IGT but showed poor performance. This pattern is similar to frontal patients. Further studies should be conducted to explore this issue. (shrink)

Online discussion forums are an essential and standard setup in online courses to facilitate interactions among learners. However, learners’ inadequate participation in online discussion forums is a long-standing challenge, which necessitates instructor intervention and the design consideration of online learning platforms. This research proposes and studies the role of mandatory participation, i.e., learners’ participation in online course forums by instructors’ requirements, in fostering their voluntary participation and boosting their learning performance. This novel effect link between mandatory participation and voluntary participation (...) has not been assessed in previous research. An empirical study is conducted using a large-scale dataset of 27,767 learners from a leading massive open online course platform in China. The findings indicate that besides its direct effect on learning performance, learners’ mandatory participation has a significant positive effect on their voluntary participation in online course forums, enhancing learning performance. Moreover, the effect of mandatory participation on voluntary participation varies across learner groups, being more prominent for early registrants than late registrants and part-time learners than full-time learners. This research contributes to the online learning literature by introducing mandatory participation as a viable approach to foster voluntary participation and boost learning performance through enhanced voluntary participation. It provides evidence on the effectiveness of the novel design feature of MOOC platforms that enables and facilitates the mandatory participation mechanism in online learning. (shrink)

According to Garfield and Priest’s interpretation, the positive use of the catuskoti by Nāgārjuna in Mūlamadhyamakakārikā (MMK) shows that he endorses a four-valued semantics similar to that of Belnap’s First-Degree Entailment (FDE), while the negative use of the catuskoti by Nāgārjuna in MMK indicates that what he really has in mind is a plurivalent five-valued semantics. This paper argues that their interpretation suffers from a number of problems: adequate logic, collapse of kotis, lack of literature support, and a suitable explanation (...) of the third koti. The final part of the paper combines insights from Westerhoff, Cotnoir, Garfield and Priest together and describes the right interpretation of Nāgārjuna’s use of the catuskoti in MMK with the right semantics and the right logic of MMK. The authors argue that Nāgārjuna’s ‘rebuttal’ of all four kotis in a catuskoti should be understood as a mere denial or a mere rejection of these kotis. (shrink)

Background and aimDuring the COVID-19 pandemic, an Internet-Mindfulness-Based Stress Reduction program was delivered and may be better than an in-person approach. Our study evaluated the effects of iMBSR intervention on mental health, self-efficacy, and body image in women with breast cancer in Taiwan.Materials and methodsSixty-seven women with breast cancer were allocated to a 6-week iMBSR program or a waitlist control group, without heterogeneity between group characteristics. Patients from both groups were measured at baseline and postintervention using three scales: Depression, Anxiety, (...) and Stress Scale, General self-efficacy scale, and Body Image Scale. Descriptive dataset analysis, paired t-test, and Student’s t-test were used to evaluate the data.ResultsAlthough iMBSR did not significantly improve depression and stress between groups, iMBSR could improve anxiety with medium effect sizes. Significant benefits were found for body image and self-efficacy, with large effect sizes.ConclusionOur preliminary study supports iMBSR as a program that can improve mental health, body image, and self-efficacy in women with breast cancer. During the COVID-19 pandemic, medical professionals can use Internet-based clinical health education. (shrink)

Red tourism, as a form of special interest tourism (SIT), becomes widespread among Chinese tourists. This study aims to explore memorable tourism experiences (MTEs) in red tourism destinations and examines how country competence affects intention to visit similar destinations through the influences on MTEs, destination image, red tourism place attachment, and overall satisfaction. The partial least squares structural equation modeling (PLS-SEM) analysis is utilized to analyze the data from 556 tourists. Empirical results reveal that country competence positively influences MTEs and (...) destination image. Furthermore, both MTEs and destination image influence overall satisfaction and red tourism place attachment, but do not influence intention to visit other similar destinations; the relationships between overall satisfaction, intention to visit other similar destinations, and place attachment are all confirmed as well. This study represents one of the few studies that classify red tourism as a form of historical-based SIT, with the purpose of promoting country competence. The outcomes provide a better understanding of both scholars and practitioners of historical-based SIT planning and businesses on how to promote destination image and country competence. (shrink)

The value–attitude–behavior and the theory of planned behavior (TPB) appear to provide limited explanation for consumer green purchase behavior. This study aims to examine the relationship between pro-environmental value, consumption value, and TPB toward green car purchasing intention among the young Chinese generation. A total of 541 student responses were collected, and the results showed that altruistic value positively influenced subjective norm (SN) and perceived behavioral control (PBC), but negatively influenced green purchase attitude (GPA). Biospheric value positively influenced GPA and (...) PBC. Function value and emotional value positively influenced GPA, respectively, and emotional value fully mediated the relationship between function value and GPA. Furthermore, GPA, SN, PBC positively influenced intention toward green car purchasing behavior, respectively, and SN mediated the relationship between GPA and intention. This study shows how pro-environmental value and consumption value can influence components of TPB in green car purchase intention. (shrink)

Previous studies have shown that the motion intention recognition for lower limb prosthesis mainly focused on the identification of performed gait. However, the bionic prosthesis needs to know the next movement at the beginning of a new gait, especially in complex operation environments. In this paper, an upcoming locomotion prediction scheme via multilevel classifier fusion was proposed for the complex operation. At first, two motion states, including steady state and transient state, were defined. Steady-state recognition was backtracking of a completed (...) gait, which would be used as prior knowledge of motion prediction. In steady-state recognition, surface electromyographic and inertial sensors were fused to improve recognition accuracy; five typical locomotion modes were recognized by random forest classifier with over 97.8% accuracy. The transient state was defined as an observation period at the initial stage of upcoming movement, in which only the sEMG signal was recorded due to the limitation of sliding window length. LightGBM classifier was validated to outperform other methods in the accuracy and prediction time of transient-state recognition. Finally, a simplified HMM model based on prior knowledge and observation result was constructed to predict upcoming locomotion. The results indicated that the locomotion prediction was over 91% accuracy. The proposed scheme implements the locomotion prediction at the initial stage of each gait and provides critical information for the gait control of lower limb prosthesis. (shrink)

Employee innovation is the cornerstone of the organization, and the motivation for employee innovative behavior largely depends on the leadership style of the leader. With the economic development of society, the traditional authoritative style of leadership can no longer adapt to the psychological characteristics of employees, who use new-era work concepts, techniques, and social rules (hereafter, new generation workers). Inclusive leadership is based on the concept of “fully inclusive and equitable” in traditional Chinese culture, and it can adapt to the (...) independent needs of new generation employees. At present, the research on the relationship between the traditional leadership style and employee innovative behavior is relatively extensive, but there is little research on the relationship between inclusive leadership style and employee innovative behavior, and this needs further exploration. This paper takes new generation employees as the sample and uses psychological capital as an intermediary variable to explore the influence of inclusive leadership style on the innovative behaviors of new generation employees. We found that inclusive leadership is significantly and positively related to new generation employees’ innovative behaviors. Theoretical and practical implications are discussed. (shrink)

Familiarity and green image influencing travelers’ green hotel patronage have often been overlooked in previous research. The aim of this study was to examine the relationship of the two dimensions of familiarity and the two dimensions of image with the overall image, satisfaction, and loyalty. The theoretical research model used in this study was based on the stimulus–organism–response framework. The research design for this study employed a quantitative approach using a purposive sampling method involving 488 student responses. The tests of (...) the proposed hypotheses were conducted using SPSS and AMOS. The results of the study showed that experiential familiarity and informational familiarity positively influenced cognitive image and affective image, respectively, while cognitive image had a positive influence on the affective image. In addition, cognitive and affective images have a positive influence on the overall image, and the overall image is shown to have a positive impact on satisfaction and loyalty. Finally, satisfaction was found to have a positive influence on loyalty, while satisfaction plays a partial meditation role in the relationship between overall image and loyalty. (shrink)

Supporting families of people with developmental disabilities from culturally diverse backgrounds is receiving increased attention in the era of globalisation. However, there is little information about how disability policy and cultural values work together to support families. This article examined how disability policy and Chinese cultural values influence family care of children and young people with developmental disabilities. By comparing qualitative interview data from Chinese families in Taipei (15) and Sydney (10), we analysed how their expression of cultural values in (...) family care differs by policy context, relative to ethics of care claims for recognition, rights and redistribution. We found that positive expressions of Chinese culture in family care fade if policies do not complement them. Policies can alleviate potential tension with cultural values in three ways: reinforcing family capacity to care; ensuring the rights of both family caregivers and people with disabilities; and extending care choices for families. These approaches resonate with ethics of care principles. We argue that culturally responsive disability policy for families means working with cultural values to achieve ethics of care. This implies that incorporating principles of ethics of care could inform cultural responsiveness in disability policy development. (shrink)

In connection with the discussion on the problem of logic, both within our country and abroad , it has already turned from the general, comparatively abstract, and difficult-to-resolve problem of the "relationship between formal logic and dialectics" to the more concrete problem of the functional scope of formal logic. Some people have even utilized special articles to inquire about a certain law in formal logic: the functional scope of the law of identity or the law of contradiction. The purpose of (...) these philosophers or logicians is to try to define the functional scope of a certain law in formal logic as a starting point, and then to proceed to study the functional scope of formal logic in the entire thinking process of mankind. If the functional scope of formal logic in mankind's entire thinking process is clearly and precisely defined, the solution of this complicated problem of the "relationship between formal logic and dialectics" would certainly not be very difficult. The basic purpose of Comrade Chu-ko Yin-t'ung's article on the problem of "whether or not formal logic's law of contradiction can be contravened in the dialectical thinking process" of men, which appeared in issue No. 82 of the "Philosophy" supplement of Kuang-ming Daily on April 24, is like this. It should be considered as a rather practical method. But I do not quite agree with his basic points of argument and with his analysis of certain examples of dialectics. I intend to present my superficial views here and to study them with Comrade Chu-ko. (shrink)

The ideas of fixed points (Kripke in Recent essays on truth and the liar paradox. Clarendon Press, London, pp 53–81, 1975; Martin and Woodruff in Recent essays on truth and the liar paradox. Clarendon Press, London, pp 47–51, 1984) and revision sequences (Gupta and Belnap in The revision theory of truth. MIT, London, 1993; Gupta in The Blackwell guide to philosophical logic. Blackwell, London, pp 90–114, 2001) have been exploited to provide solutions to the semantic paradox and have achieved admirable (...) success. This happy situation naturally encourages one to look for other philosophical areas of their further applications where paradoxical results seem to follow from intuitively acceptable principles. In this paper, I propose to extend the use of these ideas to give two new treatments of abstract objects. Sections 1 and 2 below check several abstractionist theories and their main defects. Section 3 shows how the two ideas can be applied to generate consistent theories of abstract objects without any ad hoc restriction on any principle. (shrink)

With a focus in the financial market, stock market dynamics forecasting has received much attention. Predicting stock market fluctuations is usually challenging due to the nonlinear and nonstationary time series of stock prices. The Elman recurrent network is renowned for its capability of dealing with dynamic information, which has made it a successful application to predicting. We developed a hybrid approach which combined Elman recurrent network with factorization machine technique, i.e., the FM-Elman neural network, to predict stock market volatility. In (...) this paper, the Standard & Poor’s 500 Composite Stock Price index, the Dow Jones industrial average index, the Shanghai Stock Exchange Composite index, and the Shenzhen Securities Component Index were used to demonstrate the validity of our proposed FM-Elman model in time-series prediction. The results were compared with predictions obtained from the other two models which are basic BP neural network and the Elman neural network. Some experiments showed that the FM-Elman model outperforms others through different accuracy measures. Furthermore, the effects of volatility degree on prediction performance from different stock indexes were investigated. An interesting phenomenon had been found through some numerical experiments on the effects of different user-specified dimensions on the proposed FM-Elman neural network. (shrink)

This essay is a study of Non-actualism, the thesis that there are objects which do not exist. There are several difficulties surrounding this thesis. First, there is the question about how to make sense of this very thesis. Second, there is the problem about what evidences there are for such a thesis. Third, there is a serious doubt about whether such thesis can be held consistently. ;The first question is usually claimed to be answered by Non-actualists by distinguishing two kinds (...) of quantifiers: existential quantifiers and a "broader" sort of quantifiers. My suggestion in this essay is, however, that there is a more ordinary use of the phrase "there is" which makes the Non-actualist thesis perfectly intelligible. After clarifying what I mean by "Non-actualism", especially after clarifying what the phrase "there is" is used to mean, I go on to check what evidences there are for such a doctrine. In the literature, three different sorts of evidences are usually cited by Non-actualists to defend their positions: fictional talk, modal talk, and our experiences about things not existing. I reject the first two but endorse the last one mainly on the ground that non-actual talk is subject to different interpretations and is only remotely related to ontological issues. However, there still is a threat of inconsistency for those Non-actualists who want to defend their positions from the empirical or phenomenological aspect. In this essay, I distinguish three kinds of paradoxes that a Non-actualist has to solve, and show their independence. I call them, separately, the Sosein Paradox, the Sein Paradox and the Cardinality Paradox. Further, I show that most Non-actualist theories which are designed mainly to solve these paradoxes do not really accomplish their task. But, to our surprise, there is a Meinongian thought which solves these paradoxes quite naturally, even though it did not aim at such a solution when it was developed. And I attribute this theory to Butchvarov. (shrink)

Disagreeing with most authors on vagueness, the author proposes a solution that he calls ‘three-valued semantic pluralism’ to the age-old sorites paradox. In essence, it is a three-valued semantics for a first-order vague language with identity with the additional suggestion that a vague language has more than one correct interpretation. Unlike the traditional three-valued approach to a vague language, three-valued semantic pluralism can accommodate the phenomenon of higher-order vagueness and the phenomenon of penumbral connection when equipped with ‘suitable conditionals’. The (...) author also shows that three-valued semantic pluralism is a natural consequence of a restricted form of the Tolerance principle ) and a few related ideas, and argues that ) is well-motivated by considerations about how we learn, teach, and use vague predicates.

Pain has not only sensory, but also emotional and cognitive, components. Some studies have explored the effect of pain on time perception, but the results remain controversial. Whether individual pain-related emotional and cognitive factors play roles in this process should also be explored. In this study, we investigated the effect of electrical stimulation–induced pain on interval timing using a temporal bisection task. During each task session, subjects received one of five types of stimulation randomly: no stimulus and 100 and 300 (...) ms of non-painful and painful stimulation. Pain-related emotional and cognitive factors were measured using a series of questionnaires. The proportion of “long” judgments of a 1,200-ms visual stimulus duration was significantly smaller with 300 ms painful stimulation than with no stimulus and 100 ms and 300 ms non-painful stimulation. The point of subjective equality did not differ among sessions, but the average Weber fraction was higher for painful sessions than for no-stimulus session. The pain fear score correlated positively with the PSE under 100 ms non-painful and painful and 300 ms painful stimulation. Pain catastrophizing and pain anxiety scores correlated significantly with the WF under no stimulus and 100 ms non-painful stimulation, respectively. These results suggest that electrical stimulation–induced pain affects temporal sensitivity, and that pain-related emotional and cognitive factors are associated with the processing of time perception.

We identify the \-ideals of a distributive demi-pseudocomplemented algebra L as the kernels of the boolean congruences on L, and show that they form a complete Heyting algebra which is isomorphic to the interval \ of the congruence lattice of L where G is the Glivenko congruence. We also show that the notions of maximal \-ideal, prime \-ideal, and falsity ideal coincide.

This study created a motion graphic animation about the danger of snakes within a story telling structure, which is different from a traditional science animation that relies on explanatory language to explain the scientific concept. The effects of the two types of animations on children’s attentional perception on snakes were compared by an inattentional blindness task. Three groups of children undertook the IB task with one control group who did not watch the animation and the other two groups who watched (...) the MG and the traditional styled animation, respectively in advance. The results showed that: Children who watched the animation were significantly more likely to detect the unexpected snake images in the IB task than those who did not watch the animation; Children who watched the MG animation showed a higher detection rate on the snake images than those who watched the traditional animation. The findings indicate that the intervention of animation would increase children’s attentional perception on the key concepts significantly. The MG animation has more impact than the traditional animation on children’s attentional perception on the key information. This study demonstrates that MG animation may have a significant value in promoting science education for young children that merits further explorations in depth. (shrink)

In this note we shall show that if L is a balanced pseudocomplemented Ockham algebra then the set ${\fancyscript{I}_{k}(L)}$ of kernel ideals of L is a Heyting lattice that is isomorphic to the lattice of congruences on B(L) where ${B(L) = \{x^* | x \in L\}}$ . In particular, we show that ${\fancyscript{I}_{k}(L)}$ is boolean if and only if B(L) is finite, if and only if every kernel ideal of L is principal.

Objectives: Posttraumatic stress disorder symptoms (PTSD) following past trauma could lead to psychological distress. Little is known, however, about the roles of defense mechanisms and alexithymia may play in the process. The current study aimed to examine the potential impact of alexithymia and defense mechanisms on the relationship between past trauma and distress among Chinese university students. Method: 455 university students completed a set of questionnaires: PTSD Checklists for DSM-5, Toronto Alexithymia Scale, Defense Style Questionnaire, and General Health Questionnaire-28. Results: (...) PTSD following past trauma was associated with increased psychological distress. Alexithymia and defenses (especially immature defense) mediated the path between PTSD and psychological co-morbidities. Conclusions: Following past trauma, people developed PTSD and other psychological symptoms. The severity of these distress symptoms was influenced by the way people defended themselves psychologically, as well as their ability to identify, express, and process distressing emotions.

PurposeThis study aimed to explore current developments and trends in the field of subjective well-being of older adults at a macro level and identify research hotspots.MethodsWe included reviews and articles on the SWB of older adults in the Web of Science Core Collection published from 2002 to 2021. We used CiteSpace to draw a knowledge map of the authors, institutions, countries, references, and keywords for visual analysis and used Microsoft Excel tables to count basic information details.ResultsA total of 354 papers (...) were included, and the number of papers published over the past two decades showed a pattern of growth. The core force of publications was primarily attributed to studies conducted in Europe, North America, Asia, and Oceania, which have relatively major issues of aging and good economic strength. However, links between states, institutions, and authors were relatively weak. Cluster analysis showed that the research field could be divided into eight topics: the application of social psychology in the study of the SWB of older adults, aging in older adults, health condition of older adults, achieving successful aging, interventions for SWB, age differences in SWB research, an economic perspective of SWB research and social support for older adults. Current research frontiers are socioeconomic status, community, intervention, participation, adjustment, validation, and personality.ConclusionThe results of the present study provided a comprehensive picture in the research field of SWB of older adults. It showed that the mechanism, especially the bidirectional effect, between the SWB of older adults and its influencing factors is still worthy of further exploration. More research on evidence-based and intervention strategies should be conducted in the future. (shrink)

This paper investigates the stabilization and trajectory tracking problem of wheeled mobile robot with a ceiling-mounted camera in complex environment. First, an adaptive visual servoing controller is proposed based on the uncalibrated kinematic model due to the complex operation environment. Then, an adaptive controller is derived to provide a solution of uncertain dynamic control for a wheeled mobile robot subject to parametric uncertainties. Furthermore, the proposed controllers can be applied to a more general situation where the parallelism requirement between the (...) image plane and operation plane is no more needed. The overparameterization of regressor matrices is avoided by exploring the structure of the camera-robot system, and thus, the computational complexity of the controller can be simplified. The Lyapunov method is employed to testify the stability of a closed-loop system. Finally, simulation results are presented to demonstrate the performance of the suggested control. (shrink)

Policies to promote the usage of energy-saving vehicles, such as electric vehicles and hybrids, were introduced and implemented in many countries due to increasing awareness of the potential benefits of such vehicles on environmental and energy conservation. However, despite consumers’ claims of their concerns and positive attitudes toward environmental issues, those claims have not been translated into energy-saving vehicles’ purchasing behavior. Prior studies neglected the interrelationship between consumer ethnocentrism, perceived value, and consumer knowledge in influencing consumer behavior, including pro-environmental behavior. (...) This study examines the relationship between CE, PV, CK, perceived usefulness, perceived ease of use, attitude and intention to purchase domestic energy-saving vehicles. A total of 396 completed questionnaires were collected through convenience sampling in Xuzhou, China. The survey data were subjected to descriptive analysis and analysis of variance using SPSS. In addition, confirmatory factor analysis and structural equation modeling were utilized for the hypotheses testing. The results revealed that CE positively influenced PV and CK; PV and CK positively influenced PU and PEU. CK positively influenced PV, while PU and PEU positively influenced attitude and intention, and PEU was shown to influence PU. Furthermore, attitude was shown to significantly influence intention to purchase domestic energy-saving vehicles. Lastly, the theoretical and practical implications of the outcomes were discussed, including the limitations of the research. (shrink)

This study focuses on learning effects between firms connected by common ownership. We explore the learning effects in a certain setting that how decision-makers in focal firms learn from punishments for fraudulent disclosure in their co-owned firms. Baseline results show that punishments for fraudulent disclosure in co-owned firms reduce information disclosure fraud in focal firms. The effects still exist after excluding other potential channels of learning. In mechanism analyses, similarities between focal firms and their co-owned firms and influential common shareholders (...) enhance the learning effects. Further, after the events in co-owned firms, there is improvement in internal control in focal firms, which contributes to the reduction of fraudulent disclosure. Additionally, empirical results mitigate the concern that the reduction of fraud is not driven by the learning argued in this paper but decision-makers alternatively conducting more other unethical behaviors such as real earnings management. In sum, empirical results support the existence of learning effects. As common ownership is an important but highly underexplored linkage between firms, future research can study learning effects between firms connected by common ownership in other suitable settings.

Previous research on the INTRODUCTORY IT PATTERN unveiled various lexical and grammatical aspects of its use as a grammatical stance device, including the range of the most frequently used adjectival and verbal stance lexemes, associated stance meanings, the most frequent sub-patterns, and the distinct uses in various contextual settings of the pattern. However, the stance meanings of the pattern, which are deeply rooted in the associated lexical resources, are still understudied. This study explores the meanings of the INTRODUCTORY IT PATTERN (...) by referring to the stance meanings of the pattern associated with the adjectival and verbal lexemes that are statistically attracted to the pattern. The research samples were extracted from the British component of the International Corpus of English. The samples were manually annotated for different stance types and a collexeme analysis was performed to identify the full range of stance lexemes statistically associated with the INTRODUCTORY IT PATTERN. The results show that both adjectival and verbal collexemes are statistically and functionally significant for the delivery of discrete stance types/subtypes. Adjectival collexemes are frequently deployed for all four stance types: Epistemic stance, Evaluation stance, Dynamic stance, and Deontic stance, while verbal collexemes are valuable lexical resources for the Epistemic stance, as their use entails modalized evidentiality, pointing to epistemic judgment of the writer-speaker toward events/propositions. Close examination of the use of adjectival and verbal collexemes identified three fundamental meanings of the INTRODUCTORY IT PATTERN. First, the pattern is inherently evaluative as it tends to attract more lexemes with evaluative meanings and associates evaluative meanings with superficially non-evaluative lexemes. Second, it features a scalarized expression of diversified stance types/subtypes, thus, especially reflective of the scalarized semantic feature of stance expression. Third, it connotates an overwhelmingly positive likelihood judgment. The article concludes by discussing the limitations of this study. (shrink)

This paper provides an in-depth analysis and discussion of the key issues of quality management, evaluation, and detection contained in big data for automotive application scenarios. A generalized big data quality management model and programming framework are proposed, and a series of data quality detection and repair interfaces are built to express the processing semantics of various data quality issues. Through this data quality management model and detection and repair interfaces, users can quickly build custom data quality detection and repair (...) tasks for different data quality requirements. To improve the operational efficiency of complex data quality management algorithms in large-scale data scenarios, corresponding parallelization algorithms are studied and implemented for detection and repair algorithms with long computation time, including priority-based multiconditional function-dependent detection and repair algorithms, entity detection, and extraction algorithms based on semantic information and chunking techniques, and plain Bayesian-based missing value filling algorithms, and this paper proposes a data validity evaluation algorithm and enhances the validity of the original data in practical applications by adding temporal weights, and finally it passed the experimental validation. Through the comprehensive detection process of data importance, network busyness, duration of transmission process, and failure situation, the efficiency has been increased by 20%, and an adaptive data integrity detection method based on random algorithm and encryption algorithm is designed. After experimental verification, this method can effectively detect the integrity of the data transmission process and improve the application of data value, and the final effect is increased by 30.5%.
