Mankind’s research on marketing has a history of hundreds of years, and it has been fruitful in continuous summary and research. Now the theory of marketing has gradually penetrated into the minds of every company and even individual. A successful marketing strategy is the inevitable result of scientific planning and effective implementation. However, the current marketing strategy has gradually failed to meet the needs of corporates. In order to find the best solution for corporate marketing strategy, we built a simulation (...) environment based on mobile computing and machine learning and compared the differences by simulating several companies of the same size in this city. The results of the study found that intelligent marketing based on machine learning is more suitable for enterprises than general marketing strategies. The efficiency of enterprises has increased by about 20%, and the income of enterprises has increased by more than 30% compared with traditional marketing strategies. This shows that the intelligent marketing strategy based on mobile computing and machine learning to build a simulated environment plays an extremely important role in the peculiarities. (shrink)

In this paper, we propose a method to design the pseudorandom number generator using three kinds of four-wing memristive hyperchaotic systems with different dimensions as multientropy sources. The principle of this method is to obtain pseudorandom numbers with good randomness by coupling XOR operation on the three kinds of FWMHSs with different dimensions. In order to prove its potential application in secure communication, the security of PRNG based on this scheme is analyzed from the perspective of cryptography. In addition, PRNG (...) has passed the NIST 800.22 and ENT test, which shows that PRNG has good statistical characteristics. Finally, an image encryption algorithm based on PRNG is adopted. In the encryption algorithm, the optimized Arnold matrix scrambling method and the diffusion processing based on XOR are used to obtain the final encrypted image. Through the evaluation of encryption performance, it is concluded that there is no direct relationship between the pristine image and encrypted image. The results show that the proposed image encryption scheme has good statistical output characteristics and security performance in line with cryptography. (shrink)

ObjectiveThis study aimed to develop a diagnostic model of multi-kinematic parameters for patients with amnestic mild cognitive impairment (aMCI).MethodIn this cross-sectional study, 94 older adults were included (33 cognitively normal, CN; and 61 aMCI). We conducted neuropsychological battery tests, such as global cognition and cognitive domains, and collected gait parameters by an inertial-sensor gait analysis system. Multivariable regression models were used to identify the potential diagnostic variables for aMCI. Receiver operating characteristic (ROC) curves were applied to assess the diagnostic accuracy (...) of kinematic parameters in discriminating aMCI from healthy subjects.ResultsMultivariable regression showed that multi-kinematic parameters were the potential diagnostic variables for aMCI. The multi-kinematic parameter model, developed using Timed Up and Go (TUG) time, stride length, toe-off/heel stride angles, one-leg standing (OLS) time, and braking force, showed areas under ROC (AUC), 0.96 [95% confidence interval (CI), 0.905–0.857]; sensitivity, 0.90; and specificity, 0.91. In contrast, a single kinematic parameter’s sensitivity was 0.26–0.95 and specificity was 0.21–0.90. Notably, the separating capacity of multi-kinematic parameters was highly similar to Montreal Cognitive Assessment (MoCA; AUC: 0.96 vs. 0.95). Compared to cognitive domain tests, the separating ability was comparable to Auditory Verbal Learning Test (AVLT) and Boston Naming Test (BNT; AUC: 0.96 vs. 0.97; AUC: 0.96 vs. 0.94).ConclusionWe developed one diagnostic model of multi-kinematic parameters for patients with aMCI in Foshan.

With the development of network technology, enterprises face the explosive growth of data every day. Therefore, to fully mine the value of massive data, big data analysis technology has become the key to developing the core competitiveness of enterprises. However, few empirical studies have investigated the influencing mechanism of the BDA capability of an enterprise on its operational performance. To fill this gap, this study explores how BDA technology capability influences enterprise operation performance, based on dynamic capabilities theory and resource-based (...) theory. It proposes the key variables, including the connectivity, compatibility, and modularization of big data analysis technical capability, enterprise's operational performance, and the fit between data and tools, to establish a model and study the correlation between the variables. The results highlight the mediating role of data-tool fit in the relationships between BDA capability and the enterprise's operational performance, which is a major finding that has not been underlined in the extant literature. This study provides valuable insight for operational managers to help them in mobilizing BDA capability for enterprises' operational management and improving operational performance. (shrink)

This paper focuses on the problem of target tracking using k fittest robots in a group of n mobile robots with n>k. We present centralized and distributed coordination models with all-to-all and limited communications, respectively. For the case of all-to-all communication between robots, theoretical analysis is presented to prove the exponential stability of the whole system. In real applications of robotic networks, a robot may only be allowed to exchange information with a limited number of neighbors. In such a limited (...) communication case where centralized quantity is not available, a consensus filter is used to estimate the centralized quantities in a distributed way, and a distributed competitive target tracking is thus achieved. The stability of the distributed control is also proved in theory. Finally, illustrative examples are provided and analyzed to substantiate the efficacy of the proposed models for tracking moving target in a competition manner with all-to-all communications and limited communications.

In recent years, the research of chaos theory has developed from simple cognition and analysis to practical engineering application. In particular, hyperchaotic systems with more complex and changeable chaotic characteristics are more sensitive and unpredictable, so they are widely used in more fields. In this paper, two important engineering applications based on hyperchaos pseudorandom number generator and image encryption are studied. Firstly, the coupling 6D memristive hyperchaotic system and a 2D SF-SIMM discrete hyperchaotic mapping are used as the double entropy (...) source structure. The double entropy source structure can realize a new PRNG that meets the security requirements, which can pass the NIST statistical test when the XOR postprocessing method is used. Secondly, based on the double entropy source structure, a new image encryption algorithm is proposed. The algorithm uses the diffusion-scrambling-diffusion encryption scheme to realize the conversion from the original plaintext image to the ciphertext image. Finally, we analyze the security of the proposed PRNG and image encryption mechanism, respectively. The results show that the proposed PRNG has good statistical output characteristics and the proposed image encryption scheme has high security, so they can be effectively applied in the field of information security and encryption system.

The article is devoted to the analysis of the influence of the ancient Chinese philosophy of Taiji on artistic creativity and the development of the internal evolution of artistic culture. Taoist philosophy of nature and Confucian ethics synthesized the philosophical core of the traditional Chinese worldview with its emphasis on the simplicity and naturalness of the world order, and formed the fundamental principles of Taiji. Fundamental to Taiji, the concept of Yin and Yang emphasizes the dual nature of the existence (...) of movement and variability as a balance of opposing forces of development. The Taiji philosophy of dialectical development is supplemented by the idea of ​​the genesis of renewal energy - Qi. The main research method is the method of revitalizing traditional systems on a new intellectual basis. The method of diachronic analysis of the social situation that influenced the development of Chinese neorealism in art was used. As a result of the study, the functional significance of the influence of the principles and philosophical ideas of taiji on the evolution of neorealism is described. Using the example of the work of Chinese neorealist artists Xin Dongwan and Zheng Yi, the authors come to the conclusion that there are three driving factors of artistic motivation for creativity: internal, external and subjective. The basic principles of Taiji philosophy and ethics, such as: the naturalness of change without the use of force (Wu Wei), change as the only constant in the existence of the world and its stability, gentleness - help develop the creative power of renewal. The idea is shown that in the ancient Chinese philosophical heritage, Confucianism and Taoism became two full-fledged directions, functionally complementing each other in explaining differences in cultural, political, philosophical and social environments.

This article elucidates Márkus’ new Marxist philosophy of language based on his critique of the paradigm of language represented by Popper, Wittgenstein, Lévi-Strauss, and Gadamer. His critique suggests that instrumental rationality, pure reason, alienated reason, and objective and idealistic rationality of the paradigm of language are elements that should be overcome. From his critical perspective, value rationality, practical reason, personal reason, and historical materialism are advocated instead. He not only critically develops the philosophy of language but also adds new levels (...) of meaning to Marxism. (shrink)

The current WSN is vulnerable to a variety of malicious attacks, resulting in the decline of its comprehensive performance. Multihop routing involves a number of safety and privacy issues. Problems such as snooping, sinkhole, manipulation, cloning, wormhole, spoofing, and so on affect the integrity, availability, and confidentiality of the WSNs. Therefore, this paper mainly studies the mathematical modeling of WSN multiattack behavior discrimination based on the incidence matrix. The WSN node model is used to collect relevant data and mark and (...) map the disguised data, so as to determine the characteristics of multiattack behavior and establish the WSN multiattack behavior discrimination model based on the incidence matrix. The experimental results show that the designed multiattack behavior discrimination model can distinguish the attack type according to the characteristics, has high recognition ability, can spend a short time to effectively distinguish the attack behavior, has a low false positive rate, and can effectively improve the antiattack ability of the WSN.

Individuals with high risk of internet gaming disorder showed abnormal psychological performances in response inhibition, impulse control, and emotion regulation, and are considered the high-risk stage of internet gaming disorder. The identification of this population mainly relies on clinical scales, which are less accurate. This study aimed to explore whether these performances have highly accurate for discriminating HIGD from low-risk ones. Eye tracking based anti-saccade task, Barratt impulsiveness scale, and Wong and Law emotional intelligence scale were used to evaluate psychological (...) performances in 57 individuals with HIGD and 52 matched low risk of internet gaming disorder. HIGD group showed significantly increased BIS total, attention, motor, and non-planning scores, but significantly decreased WLEIS emotion regulation score and correct rate of eye tracking anti-saccade task compared with LIGD group. BIS total score was negatively correlated with the WLEIS total and WLEIS emotion regulation scores. A combination of the WLEIS emotion regulation score and the correct rate of anti-saccade task could discriminate HIGD from LIGD with 91.23% sensitivity, 82.69% specificity, and 87.16% accuracy. Participants with higher gaming hours daily were 40 times more likely to be high risk than their counterparts. Hence, psychological performances were worse in HIGD. A combination of abnormal emotion regulation and response inhibition might be a potential marker to identify HIGD individuals. (shrink)

We present evidence that mainstream Anglophone philosophy is insular in the sense that participants in this academic tradition tend mostly to cite or interact with other participants in this academic tradition, while having little academic interaction with philosophers writing in other languages. Among our evidence: In a sample of articles from elite Anglophone philosophy journals, 97% of citations are citations of work originally written in English; 96% of members of editorial boards of elite Anglophone philosophy journals are housed in majority-Anglophone (...) countries; and only one of the 100 most-cited recent authors in the Stanford Encyclopedia of Philosophy spent most of his career in non-Anglophone countries writing primarily in a language other than English. In contrast, philosophy articles published in elite Chinese-language and Spanish-language journals cite from a range of linguistic traditions, as do non-English-language articles in a convenience sample of established European-language journals. We also find evidence that work in English has more influence on work in other languages than vice versa and that when non-Anglophone philosophers cite recent work outside of their own linguistic tradition it tends to be work in English.

Objects: With the advent of genetic technologies, many genetic/metabolic disorders can be detected asymptomatically but might be untreatable, and the benefits and risks of screening for them are not fully known. The purpose of this study is to explore current practice with regard to the parental consent process in newborn screening .Design: Staff in 23 obstetric clinics/hospitals that conduct NBS in one city of southern Taiwan were interviewed. Using content analysis, 15 interview transcripts, eight completed questionnaires, and other relevant documents (...) from the 23 clinics/hospitals were analysed to reveal the framework of the parental consent process in NBS in southern Taiwan.Main measures: Three categories—informed consent, informed dissent, and no informed/consent—were developed to analyse the parental consent process in NBS.Results: The parental consent procedures in NBS and the quality of the information provided before obtaining consent vary widely. Because the traditional NBS was incorporated into routine paediatric practices in most clinics/hospitals, the most frequently encountered consent model is “informed dissent” and “no informed/consent” ; while an “informed consent” model is the frequent model for screening rare metabolic/genetic disorders.Conclusions: Specific guidelines to regulate the parental consent process for NBS are essential. Further studies should investigate parental responses to NBS, taking these as the basis on which to establish an informed consent model in Taiwan. (shrink)

This paper approaches Husserl’s analysis of time-consciousness from a mereological perspective. Taking as inspiration Bergson’s idea that pure durée is a multiplicity of interpenetration, I will show, from within Husserlian phenomenology, that the absolute flow can indeed be described as a whole of interpenetrating parts. This mereological perspective will inform my re-consideration of the much-discussed issue of Husserl’s self-criticism concerning the schema of content and apprehension. It will also reveal a fundamental similarity between Husserl’s conception of the absolute flow and (...) Sartre’s conception of lived temporality. This paper consists of four sections. Section 2 presents the basic elements of Husserl’s mereology. Section 3 introduces the difficulty encountered by Husserl’s early account of time that makes use of the schema. I will examine Barry Dainton’s criticism of Husserl’s theory of time-consciousness against the background of the older debate between Meinong and Stern, a debate that has informed Husserl’s own account. Section 4 distinguishes two common criticisms of the schema from Husserl’s own self-criticism, which is in turn divided into two steps. It is shown how the second step of this self-criticism implies the interpenetration of the absolute flow and responds to Dainton’s criticism. Finally, Sect. 5 concludes with some comparative remarks. I will show how Husserl’s notion of absolute flow, as mereologically interpreted, anticipates Sartre’s conception of consciousness as self-transcendence, as well as how it accommodates the apparently conflicting mereological intuitions of Aristotle and Bergson.

Healthcare workers in Pakistan are still fighting at the frontline to control the spread of severe acute respiratory syndrome coronavirus-2 and have been identified as the earliest beneficiaries for COVID-19 vaccination by the health authorities of the country. Besides, the high vaccination rates of frontline healthcare workers are essential to overcome the ongoing pandemic and reduce the vaccines hesitancy among the general population. The current research employed the theory of planned behavior to investigate the COVID-19 vaccination behavior among FHWs in (...) Pakistan as well as the predictors of such behavior. Following the epidemic control and prevention policies, a sample of 680 FHWs were accessed to fill in the questionnaire evaluating the components of the TPB. Moreover, the potential role of anticipated regret and perceived susceptibility on COVID-19 vaccination behavior was also assessed. The partial least square structural equation modeling results revealed that the TPB components, as well as the AR, have positive associations with the COVID-19 vaccination behavior. The results further confirmed that PS positively affects the anticipated regret, attitude, and subjective norm to vaccinate against SARS-CoV-2. The perceived susceptibility also has a positive association with COVID-19 vaccination behavior through the mediation of anticipated regret, ATT, and SN. Our findings highlighted the importance of COVID-19 vaccination among healthcare workers, which can be applied to reduce vaccine hesitancy among the general public. (shrink)

This paper studies the feature extraction and middle-level expression of Convolutional Neural Network convolutional layer glass broken and cracked at the scene of road traffic accident. The image pyramid is constructed and used as the input of the CNN model, and the convolutional layer road traffic accident scene glass breakage and crack characteristics at each scale in the pyramid are extracted separately, and then the depth descriptors at different image scales are extracted. In order to improve the discriminative power of (...) the depth descriptor, Hellinger kernel and Principal Component Analysis are used to perform nonlinear and linear transformations. Two aggregation strategies based on depth descriptors are proposed to form a global image representation. The classification experiment of the data set shows that Hellinger kernel, PCA transformation, and two aggregation strategies are all conducive to improving the classification accuracy. In addition, the convolutional layer road traffic accident scene glass breaking and crack feature coding can obtain better classification performance than the fully connected layer feature. We conducted dynamic impact tests on plate glass and Polyvinyl Butyral- laminated glass under different boundary conditions and studied the crack propagation and failure process of the glass under different impact speeds. The results show that there are radial cracks and circular cracks on the glass specimens under the impact load; the glass specimens show partial damage under high-speed impact and the characteristics of glass breaking and cracks at the scene of road traffic accidents; the four-frame plate glass is supported by sharp dagger-like fragments. This paper compares the energy absorption of glass specimens under different boundary conditions. The results show that the energy absorption effect of the four-point supporting glass specimen is generally stronger than that of the four-frame supporting glass. (shrink)

As the world has turned into a global village, it has created many challenges for human resource departments regarding the management of a diverse workforce in satisfying the employees and creating a diverse yet safe environment for them that does not make them uncomfortable. The current study has investigated the effect of human resource practices on the diversity climate with the mediation of job satisfaction. The data has been collected from human resource personnel of multinationals in China with the help (...) of 316 participants. The study deployed SEM analysis to analyze and measure the effect of training and development along with performance appraisal on the diversity climate. The findings of the study revealed that training and growth or development do not have an impact on the diversity climate, however, performance appraisal has a strong positive impact. Similarly, the mediating role of job satisfaction has been found to ensure the relationship of training and development and performance appraisal with the diversity climate. This study has provided certain implications for the HR managers of multinationals to ensure a secure diversity climate for a diverse workforce. (shrink)

In this article, I analyze the evolution of Husserl's view on the normativity of logic and the corresponding changes in his phenomenological analysis of judgment. Initially, in the Prolegomena, Husserl claimed that the laws of pure logic are ideal and acquire normative status only as a result of application. Later, however, he revised this position and claimed that the same laws are at once ideal and normative. Sections 1 and 2 present textual evidence for attributing such a change of position (...) to Husserl, which is not generally acknowledged in the literature. Section 3 critically examines Husserl's early position, with specific attention to the model of instantiation. Sections 4–6 identify three key stages in the development of Husserl's theory of judgment that lead to the normative conception of pure logic: (1) the critique of the dissociation of ideal content and assertive force; (2) the rejection of the instantiation model of proposition and the development of a new account in terms of identification; (3) the genetic‐phenomenological interpretation of proposition and the elaboration of the three‐layer structure of pure logic.

Modern philosophy of art includes the philosophy of film as a well-established subfield. (...) Although philosophers were among the first academics to write studies of the new art form in the early decades of the twentieth century, the area did not enjoy considerable development until the 1980s, when a resurgence began. The rapid expansion of this sector can be attributed to a wide variety of factors. Let it be enough to state that the evolution of philosophy as a discipline and the growing importance of cinema in popular culture has made it crucial for philosophers to view the film as an art form on par with literature, music, and the visual arts. The overall research study found that there are negative and some positive relations between aesthetic philosophy and practical philosophy in music production.

In 1879, Wilhelm Marr coined the term ‘Antisemitismus’, which aroused extensive discussion in academic circles. With the deepening of research, scholars’ research on anti-Semitism gradually traced back to the ancient world. Texts with anti-Semitic thought appeared as early as Ptolemaic Egypt. Essentially, the main purpose of these words were self-justification, a response to the sinful image of the Egyptians in the narrative of Exodus. The early Ptolemaic Egyptian writers got rid of the charges against the Egyptians by rewriting the narrative (...) of Exodus and shifting responsibility for the entire event to the Jews. It is obvious that in the process, the image of the Jewish people has been severely vilified. Although the writers did not express a strong anti-Semitic tendency subjectively, they all expressed a certain degree of anti-Semitic thought objectively. The anti-Semitic thought was inherited by later writers in the Roman world and had a profound impact. This article focuses on the works of three Ptolemaic Egyptian writers and discusses their reasons and influences for rewriting the narrative of the Exodus in combination with their historical background. Contribution: This article discusses the origin and spread of anti-Semitic thought in the ancient world. It has important reference value for the study of ancient writers’ understanding of the Old Testament. At the same time, it has important academic value for the study of Jewish history. (shrink)

Biomedical moral enhancement, or BME for short, aims to improve people’s moral behaviors through augmenting, via biomedical means, their virtuous dispositions such as sympathy, honesty, courage, or generosity. Recently, it has been challenged, on particularist grounds, however, that the manifestations of the virtuous dispositions can be morally wrong. For instance, being generous in terrorist financing is one such case. If so, biomedical moral enhancement, by enhancing people’s virtues, might turn out to be counterproductive in terms of people’s moral behaviors. In (...) this paper, we argue, via a comparison with moral education, that the case for the practice of biomedical moral enhancement is not weakened by the particularists’ stress on the variable moral statuses of the manifestations of our virtues. The real challenge from the particularists, we argue, lies elsewhere. It is that practical wisdom, being essentially context-sensitive, cannot be enhanced via biomedical means. On the basis of this, we further argue that BME ought to be used with great caution, for it may wrongly enhance, for instance, a terrorist financier’s generosity, a robber’s courage, or an undercover detective’s honesty. Finally, we sketch how boundaries can be set on the use of BME, and address some potential objections to our position. (shrink)

If philosophical moral reflection tends to promote moral behavior, one might think that professional ethicists would behave morally better than do socially comparable non-ethicists. We examined three types of courteous and discourteous behavior at American Philosophical Association conferences: talking audibly while the speaker is talking (versus remaining silent), allowing the door to slam shut while entering or exiting mid-session (versus attempting to close the door quietly), and leaving behind clutter at the end of a session (versus leaving one's seat tidy). (...) By these three measures, audiences in ethics sessions did not appear to behave any more courteously than did audiences in non-ethics sessions. However, audiences in environmental ethics sessions did appear to leave behind less trash. (shrink)

Organoids and specifically human cerebral organoids (HCOs) are one of the most relevant novelties in the field of biomedical research. Grown either from embryonic or induced pluripotent stem cells, HCOs can be used as in vitro three-dimensional models, mimicking the developmental process and organization of the developing human brain. Based on that, and despite their current limitations, it cannot be assumed that they will never at any stage of development manifest some rudimentary form of consciousness. In the absence of behavioral (...) indicators of consciousness, the theoretical neurobiology of consciousness being applied to unresponsive brain-injured patients can be considered with respect to HCOs. In clinical neurology, it is difficult to discern a capacity for consciousness in unresponsive brain-injured patients who provide no behavioral indicators of consciousness. In such scenarios, a validated neurobiological theory of consciousness, which tells us what the neural mechanisms of consciousness are, could be used to identify a capacity for consciousness. Like the unresponsive patients that provide a diagnostic difficulty for neurologists, HCOs provide no behavioral indicators of consciousness. Therefore, this article discusses how three prominent neurobiological theories of consciousness apply to human cerebral organoids. From the perspective of the Temporal Circuit Hypothesis, the Global Neuronal Workspace Theory, and the Integrated Information Theory, we discuss what neuronal structures and functions might indicate that cerebral organoids have a neurobiological capacity to be conscious.

Introduction: Few studies are available on the prevalence and sleep-related factors of dementia with Lewy bodies (DLB) in Chinese older adults, aiming to explore the associations between sleep characteristics and DLB.Methods: A cross-sectional study with 7,528 individuals aged ≥65 years in 106 communities in Northern China was conducted from April 2019 to January 2020. Questionaries (including demographic characteristics, comorbidities, lifestyles, and sleep characteristics) were administered, and neuropsychological assessments and physical examination were conducted in phase I; screening for probable DLB was (...) done in phase II. Logistic regressions were used to assess associations.Results: A total of 919 (12.2%, 919/7,528) participants had dementia, and 101 (1.3%, 101/7,528) participants were diagnosed with DLB. The prevalence of dementia and DLB were slightly higher or equal in women, increased with age, and roughly decreased with nighttime sleep duration. Of the 101 participants, all of them (100.0%) had cognitive impairment, 46 (44.54%) displayed fluctuating cognition, 72 (71.29%) of them showed visual hallucination, 22 (21.78%) individuals reported RBD, and 27.71% showed Parkinsonism. Sleeping for 8 h had combined diagnostic value for DLB (AUC = 0.783, 95%CI: 0.734–0.831, p < 0.001).Conclusions: The current prevalence of DLB is 1.3% in Northern China. Short or long nighttime sleep duration is independently associated with the occurrence of dementia and DLB. (shrink)
