Ultrasonic excitation has been widely used in the detection of microcracks on metal surfaces, but there are problems such as poor excitation effect of ultrasonic pulse, long time to reach the best excitation, and difficult to find microcracks. In this paper, an adaptive ultrasonic pulse excitation device and infrared thermal imaging technology have been combined, as well as their control method, to solve the problem. The adaptive ultrasonic pulse excitation device adds intelligent modules to realize automatic adjustment of detection parameters, (...) which can quickly obtain reliable excitation; the multidegree-of-freedom base realizes the three-dimensional direction change of the ultrasonic gun to adapt to different excitation occasions. When the appropriate ultrasonic excitation makes microcracks in the resonance state, the microcracks can be frictionated, which produce heat rise with the temperature. Then, the microcrack defect can be detected by the infrared thermal instrument through the different surface temperatures with imaging recognition method. Our detection experiments of the titanium alloy plates and the aluminum alloy profiles of marine engineering show that the method can get reliable detection parameters in a short time and measure the crack length effectively. It can be used in many aspects such as crack detection in mechanical structures or complex equipment operating conditions and industrial production processes. (shrink)

Frustration is often seen as negative, but as to whether it may have a positive impact on the individual is still undecided. This research was conducted to explore the influence of frustration on altruistic tendency and altruistic level in college students. By presenting a highly difficult task combined with negative feedback, we effectively induced frustration in Experiment 1. By assessing the donation behavior of participants in a real-life scenario following the experimental manipulation of frustration, we examined the relationship between frustration (...) and altruism in Experiment 2. Results showed that frustrating situations could, on some level, improve altruistic behavior [t = 3.013, p = 0.015]. More specifically, among participants who donated, the amount donated was higher in the frustration group compared to the control group; the proportion of people who donated did not differ by group.

Cognitive and neural processes underlying visual creativity have attracted substantial attention. The current research uses a critical time point analysis to examine how spontaneous activity in the primary visual area is related to visual creativity. We acquired the functional magnetic resonance imaging data of 16 participants at the resting state and during performing a visual creative synthesis task. According to the CTPA, we then classified spontaneous activity in the PVA into critical time points, which reflect the most useful and important (...) functional meaning of the entire resting-state condition, and the remaining time points. We constructed functional brain networks based on the brain activity at two different time points and then subsequently based on the brain activity at the task state in a separate manner. We explore the relationship between resting-state and task-fMRI functional brain networks. Our results found that: the pattern of spontaneous activity in the PVA may associate with mental imagery, which plays an important role in visual creativity; in comparison with the RTPs-based brain network, the CTP-network showed an increase in global efficiency and a decrease in local efficiency; the regional integrated properties of the CTP-network could predict the integrated properties of the creative-network while the RTP-network could not. Thus, our findings indicated that spontaneous activity in the PVA at CTPs was associated with a visual creative task-evoked brain response. Our findings may provide an insight into how the visual cortex is related to visual creativity. (shrink)

In four experiments, we explored the inferences people make when they learn that counterfactual thinking has occurred. Experiment 1 showed that knowing that a protagonist had engaged in counterfactual thinking resulted in participants inferring that the past event was closer in time to the protagonist, but there was no difference in inferring how close the past event was between knowing that a protagonist made many or a single counterfactual statement. Experiment 2 confirmed that participants were not affected by the number (...) of counterfactual statements they read when inferring temporal closeness. Experiment 3 demonstrated that participants who learned that a protagonist had engaged in counterfactual thinking were more likely to infer that the protagonist experienced the controllable event. Experiment 4 indicated that participants who learned that a protagonist had engaged in counterfactual thinking were more likely to infer that the protagonist experienced the exceptional event. We concluded that the existence of counterfactual thoughts can lead people to infer that events were close, exceptional, and controllable, which suggests that the relations between closeness/controllability/exceptionality and counterfactual thinking are bidirectional. These results showed that as well as making inferences based on facts about the real world, people also make inferences about the real world based on hypothetical worlds. (shrink)

Despite China’s recent remarkable performance in high-quality research, the number of students going abroad to pursue doctoral degrees in STEM fields has been rising rapidly. This study investigates the motivations of Chinese international doctoral students in STEM fields for undertaking a PhD abroad, and the external factors influencing this major life decision. Based on in-depth interviews with 35 CIDS from seven universities in four Australian states, the findings show that for the current generation, enriching life experiences and self-cultivation emerged as (...) most prominent personal motivations. The choice to study abroad, though ultimately a personal decision, was influenced by a range of factors and particularly long-term cooperation between host and home institutions. Both academic and personal reputation of supervisors played important roles in the selection of host institutions. This study may be of value to supervisors and higher education policy-makers, at institutional and govern... (shrink)

Adolescents' community violence exposure has been demonstrated with a range of behavioral and psychological problems, but the processes that explain these correlations are not clear. In our 2017 study, the mediating role of deviant peer affiliation in the relationship between CVE and externalizing problem behaviors has been confirmed. However, the moderating effect of parental factors is still unclear. Therefore, a new group was adopted in this study to further explore the moderating effect of parental knowledge based on also confirming the (...) mediating effect of deviant peer affiliation. Stratified-cluster sampling was used to recruit 1,797 volunteers who completed questionnaires on CVE, deviant peer affiliation, parental knowledge, and externalizing problem behaviors. The results of the structural equation modeling were: on the basis of our previous research, we further analyzed the mediating role of deviant peer affiliation, and the mediated association was moderated by parental knowledge. Especially when the school climate is added as a covariate, the moderating effect of parental knowledge has changed, that is, the positive association between CVE and externalizing problem behaviors was much stronger for adolescents who reported lower levels of parental knowledge than for those who reported higher levels of parental knowledge. The results support the assumptions of social learning theory and have implications for interventions of community violence. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Journal of the History of Ideas 63.1 (2002) 1-17 [Access article in PDF] What if the Father Commits a Crime? Rui Zhu Apparently, Socrates and Confucius respond similarly to the question if a son should turn in his father in the case of the father's misdemeanor. When Euthyphro, flaring his pride of his moral impartiality, tells Socrates that he is on his way to report his father because he (...) has thrown one of the household slaves into a ditch and left him bound there until he was dead, Socrates says, "Good Heaven! Certainly, Euthyphro, most men would not know how they could do this and be right. It is not the part of anyone to do this, but of one who is far advanced in wisdom." 1According to Socrates, only a man of high wisdom knows how to prosecute his father righteously, but Euthyphro does not appear to have this wisdom. When his interlocutor observes that an upright man in his state would bear witness against his father if he misappropriates a sheep, Confucius contradicts the interlocutor's understanding of uprightness by speaking in a matter-of-fact tone: "In my country the upright men are of quite another sort. A father will cover up for his son, and a son his father—which incidentally does involve a sort of up—rightness." 2Confucius stands on the same line with Socrates but seems the more radical of the two. Socrates does not directly refute Euthyphro and only suggests that he make sure he understands what he is doing before going any further. Socrates is not only typically Socratic—indirect and suggestive—but also sounds so reasonable that Euthyphro appears in contrast to be a reckless youth who harbors [End Page 1] only a faint understanding of morality. Confucius's response is more rigid, for he categorically dismisses an act of the Euthyphroian kind. He demands that father and son cover up for each other in the case of either one's guilt. Compared to Socrates, Confucius advocates the position that seems a little too strong and leaves no room for justice, while Socrates does not have that problem with justice. This is how we feel about Socrates and Confucius on our first impression. The prima facie observations that we make from the remarks of Socrates and Confucius seem both plain and unproblematic.By embedding these remarks into their respective social or philosophical cultures, this paper will show that our previous observations are not quite accurate. The apparent affinity of the Socratic and Confucian stances belies different underlying moral philosophies. We want to use their comments as bridges to explore the early Greek and Confucian ethics and show how different a picture we see after things are examined within their traditions.The issue of a possible father-son conflict may be treated as a case study of the early Greek (the Heroic era until the age of Socrates) and early Confucian (Confucius and Mencius) morals. There is a strong theme in the early Greek morals that allows, or sometimes demands, a son such as Euthyphro to prosecute his father for the sake of justice, because justice, instead of love (philein) or filial piety, is the governing principle in the early Greek ethics. Confucian ethics is founded on love (human-heartedness), which in turn is extended from the love between father and son. All moral principles including justice are derived from this extension of love. The mutual love of father and son then becomes the governing principle in the case of Confucianism. A Guilty Father: The Greek Motif The question, "What if the father commits a crime?" has a certain realistic aroma to a boy coming of age in the Hesiodic Greek world. That father has to be overcome by son before some relief from strife becomes possible is a familiar theme in Greek literature. In Hesiod's Theogony, Uranus (the sky) incurs hatred from all his newborn children since he hides them in their mother Gaia's womb and does not let them return to the light, for no reason...

ObjectiveThe level of health literacy is one of the important factors affecting health outcomes. Family is an important place to shape personality traits, and people with different personalities will adopt different lifestyles, which will lead to variations in health outcomes. Therefore, this article aims to explore the relationship between health literacy and personality and its influencing factors in different family structures.MethodsThis was a cross-sectional study with 1,406 individuals. A questionnaire was utilized to measure health literacy, personality and demographic variables, including (...) family structure. Canonical correlation analysis and hierarchical multiple regression analysis were used to examine the relation between health literacy and personality traits between two types of family structure.ResultsCCA showed that the canonical correlation coefficients were 0.309 and 0.347, in two-parent family and single-parent family, respectively. The openness of personality traits exhibited the highest correlation with health literacy. Compared with the remaining personality traits, openness yielded the strongest effect in two types of family structure, respectively. Education and monthly income were significantly associated with health literacy.ConclusionOur results support the relation between health literacy and personality traits in two types of family structure.

In nontheistic moral traditions, there is a typical ethical conundrum concerning the relation between cosmic order and human agency. Within those traditions, it is generally recognized that the universe has its own order and history that are independent of human will. A moral discourse has to find space to accommodate human agency in the midst of the iron grid of cosmic law. Both Confucius and Aurelius use the concept of timeliness (kairos) to resolve the difficult issue. But their philosophies take (...) on divergent paths. By studying their resolutions of the issue, we will be able to appreciate the distinctive nature of their nontheistic moral narratives. (shrink)

As one of the three systems of China's traditional culture, Daoism has an important place in the history of Chinese philosophy. Based on the ideas of inaction performing all, the Way modeling spontaneity, and the dialectic of you [having, being] and wu [lacking, nonbeing], this article is a systematic exploration of Laozi's philosophy of denial, spontaneity, and atheism, as well as of the deep and lasting influence of his metaphysical principles on all schools of traditional Chinese philosophy.

Abstract In ?On Making an Effort? E. J. Coffman develops what he takes to be a fairly serious problem for Robert Kane's positive theory of free choice, where the concept of efforts of will is pivotal.1 Coffman argues that the plausibility of Kane's libertarian account of free choice ?is inversely proportional to the plausibility of a certain principle of agency? (p. 12). And since the latter is quite plausible, the former is therefore ?at best fairly implausible? (p. 12). In what (...) follows I will show that Coffman's objection is in fact misplaced. Kanean libertarianism not only is in accordance with the essence of the principles of personal responsibility that Coffman advocates, it also affords a more plausible and intelligible account of the sources of personal responsibility superior to the proposed principles.
