The twenty-first century is arguably the century of computing. In such a world saturated by computing, Computational Thinking is now recognized as a foundational competency for being an informed citizen and being successful in STEM work. Nevertheless, how to effectively import different types of teaching methods in university courses is subjected to further evaluation. Currently, the arguments in favor of tangible robots including high interaction, great practicality, and specific operation results make themselves to be often used as a teaching medium (...) and tool for teaching activities between teachers and students. Hence, in addition to cultivating students with computational thinking ability, this paper discussed how to integrate tangible robots into project-based learning courses of thinking skills training to improve the learning performance of the computational thinking ability. This study conducted in one semester on the 105 students from three classes. Experimental results show that the project-based learning method integrated with the teaching material of robotic visual programs approach had significantly better effectiveness in improving students' learning achievements than the traditional teaching method integrated with paper practice teaching materials approach. Analysis of the questionnaire results showed that the proposed learning approach did not increase the students' cognitive burden. In sum, the proposed approach helps students' learning achievement and cognitive load. (shrink)

This paper studies a special scheduling problem under hierarchical management in nurse staff. This is a more complex rostering problem than traditional nurse scheduling. The first is that the rostering requirements of charge nurses and general nurses are different under hierarchical management. The second is that nurses are preferable for relative fair rather than absolute fair under hierarchical management. The model aims at allocating the required workload to meet the operational requirements, weekend rostering preferences, and relative fairness preferences. Two hybrid (...) heuristic algorithms based on multiobjective grey wolf optimizer and three corresponding single heuristic algorithms are employed to solve this problem. The experimental results based on real cases from the Third People’s Hospital, Panzhihua, China, show that MOGWO does not as good as it does on other engineering optimization. However, the hybrid algorithms based on MOGWO are better than corresponding single algorithms on generational distance and spacing of Pareto solutions. Furthermore, for relative fair rostering objective, NSGAII-MOGWO has more power to find the optimal solution in the dimension of relative fairness. (shrink)

This study examines the influence of three components of corporate social responsibility on team performance. In the proposed model of this study, team performance is indirectly affected by three dimensions of perceived corporate citizenship (i.e., economic, legal, and ethical citizenship) via the mediation of team efficacy and team self-esteem. Surveying members of 172 teams confirms most of our hypothesized effects. Our results show that economic citizenship influences team performance via the mediation of both team efficacy and team self-esteem. However, legal (...) citizenship influences team performance via team efficacy alone, whereas ethical citizenship influences team performance only via team self-esteem. We discuss the theoretical and managerial implications of our findings. (shrink)

Perhaps one of the most pervasive behaviours in organisations is individual silence. Although individual silence may be triggered by various motives, prior research has predominantly discussed individual silence from the dark side. Thus, individual silence has been viewed as a dysfunctional and antisocial workplace behaviour. In this article, we take a bright perspective by incorporating virtues into the discussion of individual silence. Specifically, we propose the concept of virtuous silence to capture individuals' inclination to remain silent in order to feel, (...) think, and act in ways that contribute to the common good within the organisation. Additionally, virtuous silence contains the following key characteristics: 1) it is driven by an individual's natural propensity for righteousness and collective prosperity; 2) it is a dyadic behaviour; 3) it is a communicative behaviour that focuses on engaging oneself and others in deeper thinking and reasoning. Theoretical contributions and managerial implications are discussed. (shrink)

According to the spreading hypothesis of object-based attention, a subliminal cue that can successfully capture attention to a location within an object should also cause attention to spread throughout the whole cued object and lead to the same-object advantage. Instead, we propose that a subliminal cue favors shifts of attention between objects and strengthens the between-object link, which is coded primarily within the dorsal pathway that governs the visual guidance of action. By adopting the two-rectangle method and using an effective (...) subliminal cue to compare with the classic suprathreshold cue, we found a different result pattern with suprathreshold cues than with subliminal cues. The suprathreshold cue replicated the conventional location and object effects, whereas a subliminal cue led to a different-object advantage with a facilitatory location effect and a same-object advantage with an inhibitory location effect. These results support our consciousness-dependent shifting hypothesis but not the spreading hypothesis. (shrink)

This study proposed a children’s digital art ability training system with artificial intelligence-assisted learning, which was designed to achieve the goal of improving children’s drawing ability. AI technology was introduced for outline recognition, hue color matching, and color ratio calculation to machine train students’ cognition of chromatics, and smart glasses were used to view actual augmented reality paintings to enhance the effectiveness of improving elementary school students’ imagination and painting performance through the diversified stimulation of colors. This study adopted the (...) quasi-experimental research method and designs the pre-test and post-test for different groups. The research subjects are the Grade 4 students of an elementary school in Taitung City, Taiwan. The test tools included an imagination test and an evaluation of painting performance ability. The test results of a total of 30 students before and after the experiment included the experimental group that received the children’s digital art ability training system with AI-assisted learning and 30 students in the control group that had not received the teaching were analyzed by covariance. These results were supplemented by the description and interpretation of student feedback, teachers’ reflection notes, and other qualitative data to understand the performance of the students in the experimental group in terms of imagination and painting performance.

From the popularity of flipped teaching in United States primary and high schools, it is thought that students have more learning control to adjust to the learning progress and are assisted in problem solving and learning guidance during class period. It is believed that flipped teaching could prompt underachieving learners’ active learning and thereby enhance learning effectiveness. A total of 386 high school students in Chungli, Taiwan, were part of an experimental study and the research results are summarized below: Students (...) who participated in the flipped teaching models demonstrated better comprehension levels with the teaching content due to this change in learning style and attitude, which in turn, enhanced learning effectiveness. To eliminate poor language performance of underachieving students, it is necessary to lay solid foundations to gradually enhance language learning effectiveness regarding this particular group of students. Films suitable for students’ individual ability could be combined with new language learned in the unit to genuinely assist underachieving learners’ language learning effectiveness. For students who care about their performance, a “system of play” style grouping should be determined in order to enable the tracking of group performance and term performance. According to the results, further developments regarding active learning ability, boosts in learning interests, enhanced learning effectiveness, and the prompting of creativity resulting in a shift from passive learner to active learner have been proposed.

The financial crisis of 2007–2008 and the COVID-19 pandemic have caused many enterprises to suffer great losses. Thus, companies have to take measures such as pays cut, furloughs, or layoffs, which caused dissatisfaction among employees and triggered labor disputes. Therefore, this study explores the service-oriented organizational citizenship behavior based on the decomposed theory of planned behavior in order to understand the behavioral intentions of employees through their mental states, job attitudes, subjective norms, and perceived behavioral control. This study conducted questionnaire (...) surveys for employees in different industries, collected 281 valid questionnaires, and applied Structural Equation Model for the analysis. The results show: employees believe organizational justice in the organization is important, and when they feel treated fairly, their job attitudes and beliefs are enhanced. Employees’ job attitudes and beliefs support service-oriented organizational citizenship behavior, in other words, they have positive job attitudes and beliefs and will actively provide better service to customers. When employees are treated reasonably and fairly by the organization and have positive job attitudes and perceived behavior control, their spontaneous service-oriented organizational citizenship behavior is stimulated, thus increasing organizational development.

Given that citizenship challenges the basis and workings of the basic institutions market, state, and civil society, organizational citizenship behaviors (OCBs) become an important moral tenet found in some codes of ethical principles. This study explores service-oriented OCBs and their determinants. Three dimensions of service-oriented OCBs (loyalty, service delivery, and participation) are hypothetically influenced by distributive justice, procedural justice, personal cooperativeness, and the need for social approval through the mediation of organizational commitment. The three dimensions of OCBs are hypothetically influenced (...) by personal cooperativeness, need for social approval, task interdependence, and outcome interdependence through the mediation of social network ties. The model is tested using data from contact employees at several financial holding companies in Taiwan. Test results reveal that the relationships between need for social approval and organizational commitment and those between task interdependence and social network ties are insignificant, whereas all other paths are significant. This study also provides managerial implications and limitations. (shrink)

Given the widespread acceptance of computational thinking in educational systems around the world, primary and higher education has begun thinking about how to cultivate students' CT competences. The artificial intelligence of things combines artificial intelligence and the Internet of things and involves integrating sensing technologies at the lowest level with relevant algorithms in order to solve real-world problems. Thus, it has now become a popular technological application for CT training. In this study, a novel AIoT learning with Augmented Reality technology (...) was proposed and explored the effect of CT skills. The students used AR applications to understand AIoT applications in practice, attempted the placement of different AR sensors in actual scenarios, and further generalized and designed algorithms. Based on the results of the experimental course, we explored the influence of prior knowledge and usage intention on students' CT competence training. The results show that proposed AIoT learning can increase students' learning intention and that they had a positive impact on problem solving and comprehension with AR technology, as well as application planning and design.

Against the backdrop of economic internationalization and market globalization, the world has witnessed faster competitive contents with a more dynamic market environment, a more rapid technological innovation, and more diverse customer needs. Thus, for every enterprise especially led by entrepreneurs, the focus is to maintain the sustainability of competitive advantages and dynamically transform core capacity to avoid rigidity. This paper introduces the process of the deepened rigidity in WS Co. Company, which occurs due to the wrong cognition of Dr. S (...) and his teams who managed or failed to respond to the rigidity encountered by the company during different periods. The rigidity of its capacity is believed to be caused by the cognitive errors of the entrepreneur and his team facing every period of potential rigidity, which makes them fail to deal with it, thus leading to complete rigidity. This paper intends to explain how rigidity takes shape from the cognitive aspect of senior managers, which may serve as illuminations for the similar enterprises led by entrepreneurs. (shrink)

The objective of this study is to investigate the effects of emotional labor on job performance and satisfaction, as well as to examine the mediating effect of sleep problems and the moderating effects of personality traits. A time-lagged study was conducted on 864 health professionals. Scales for emotional labor, sleep, personality traits, and job satisfaction were used and job performance data was obtained from records maintained by human resources. Structural equation modeling was performed to investigate the relations. Sleep problems only (...) partially mediated the relationship between surface acting and job satisfaction but completely mediated the relationship between surface acting and job performance. Several personality traits were shown to moderate the relationship between surface acting and sleep problems. The effects were stronger for people with low agreeableness and high neuroticism. The relationship between high levels of deep acting and low levels of sleep problems was more pronounced in individuals with low extraversion. Supervisors should be conscious of emotional labor in the work context and provide necessary deep acting training to facilitate emotional regulation. (shrink)

Lü-shih ch'un-ch'iu [Spring and Autumn of the House of Lü] appeared on the scene in 239 B.C. This was the latter part of the Warring States period. Our country's transition from slavery to feudalism had already been basically completed, but chaotic wars of secession among the feudal princes still occurred. Remnant forces of the slave system were still quite strong, and the restoration-counterrestoration struggle between the declining slave-owning class and the newly emerging landlord class was proceeding violently. Lü Pu-wei (...) was a careerist and plotter of the declining slave-owning class and a representative of the Confucians. In response to the needs of the slave-owning class's counterrevolutionary restoration, Lü adopted the tactic of "attacking the mind." He sneaked into the government of the newly emerging landlord class in the state of Ch'in and played the role of an ardent vanguard for restoration. This big commercial slave owner, who had originally run around among Ch'in, Chao, and other states, had amassed thousands of gold pieces at home and possessed more than ten thousand slaves. He played around with political conspiracies and became chancellor of the state of Ch'in. Before King Ying Cheng of Ch'in personally took power in 238 B.C., political power fell for a time into Lü's hands. Lü Pu-wei worked in collusion with Lao Ai, a eunuch he sponsored, and joined the industrial and commercial slave owners and the aristocratic slave owners to form a frenzied restorationist force. On the one hand, they formed factions to strengthen private interests, expanded their power, and prepared for an armed coup d'état. On the other hand, they took in riff-raff [literally, people who had surrendered and rebelled], assembled Confucian scholars, set to work on ideology, and grandly created public opinion for the restoration of the slave system. At that time, a reactionary adverse current favoring the restoration of the slave system hung over the state of Ch'in. Lü-shih ch'un-ch'iu, which was compiled under Lü's direction by his retainers, was the product of this adverse current. (shrink)

BackgroundBreast cancer patients are at elevated risk of depression during treatment, thus provoking the chance of poor clinical outcomes. This retrospective cohort study aimed to investigate whether integrating Chinese herbal medicines citation into conventional cancer therapy could decrease the risk of depression in the long-term breast cancer survivors.MethodsA cohort of patients aged 20–70 years and with newly diagnosed breast cancer during 2000–2008 was identified from a nationwide claims database. In this study, we focused solely on survivors of breast cancer at (...) least1 year after diagnosis. After one-to-one matching for age, sex, and baseline comorbidities, breast cancer patients who received and did not receive CHM treatment were enrolled. The incidence rate and hazard ratio citation for depression between the two groups was estimated at the end of 2012. A Cox proportional hazard model was constructed to examine the impact of the CHM use on the risk of depression.ResultsDuring the study period, the incidence rate of depression was significantly lower in the treated cohort than in the untreated cohort [8.57 compared with 11.01 per 1,000 person-years citation], and the adjusted HR remained significant at 0.74 in a Cox proportional hazards regression model. The corresponding risk further decreasing to 43% among those using CHM for more than 1 year.ConclusionFinding from this investigation indicated that the lower risk of depression observed in breast cancer patients treated with CHM, suggesting that CHM treatment should be considered for disease management toward breast cancer. Yet, the optimal administered dose should be determined in further clinical trials. (shrink)

The philosophical thought of the Ch'un-ch'iu period was derived and developed from the thought of the Yin dynasty and the Western Chou , there being an inseparable relationship of succession and transformation between them. Thus, in studying the philosophical thought of the Ch'un-ch'iu period, it is necessary to refer back to Yin-Chou thought. The courage and resolve evidenced by an attitude of so-called "cutting off the miscellaneous streams" in order to start with Lao Tzu or Confucius is really (...) a very awkward way of dissecting history.
