This paper probes the structure of moral feeling and reason described by Mencius's from five perspectives: (1) In view of the relationship between feeling and reason, is it better to use the expression "siduan" or the expression "sixin (Four Heart-minds)"? (2) In view of dispositional feeling, what are the four original sources? (3) In view of moral feeling, what are the structural order of the four sources and the corresponding procedure of reasoning of four heart-minds of Humanity? (4) In view of positive feeling, how does moral feeling grow out of the goodness of human nature? (5) What is the global value of Mencius's ideas on human moral feeling? The author concludes that Mencius's thought on moral feeing has a global value and cross-cultural significance, and that Chinese wisdom is more than regional but universally applicable. The structure of moral feeling and reason that Mencius identified is in accordance with the principles ofzhiliang (grasping the two poles of the beginning and the end) and yongzhong (emloying the middle). The principles ofzhiliang and yongzhong are true universal wisdoms of Confucianism, which should be rekindled today. From a practical point of view, "the Way begins from moral feelings," and Confucius and Yah Hui's seeking the simple, virtuous life is an ideal model of emotional well-being.展开更多

Doublelabeling staining was used to display the distribution of Bcl-2^+/ki-67 cells in 162 cases of GC and its matched normal mucosa and precancerous lesion.RESULTS: The positive rate of Bmi-1 expression in GC(52.5%) was significantly higher than that in normal gastric mucosa (21.6%, X^2 = 33.088, P 〈 0.05). The Bmi-1 expression in GC was closely related with the Lauren's and Borrmann's classification and clinicalstage (X^2 = 4.400, 6.122 and 11.190, respectively, P〈 0.05). The expression of ki-67 was related to the Borrmann's classification (X^2 = 13.380, P 〈 0.05).Bcl-2 expression was correlated with the Lauren's classification (Z2 = 4.725, P 〈 0.05), and the Bmi-1 expression both in GC (rk = 0.157, P 〈 0.05) and inintestinal metaplasia (rk = 0.270, P 〈 0.05).CONCLUSION: Abnormal Bmi-1 expression in GCmay be involved in cell proliferation, apoptosis andcancerization. This marker can objectively indicate theclinicopathological characteristics of GC.展开更多

Fichte's notion of the pure I (ieh) serves as the theoretical starting-point for his exposition of transcendental idealism, and in many ways this concept is analogous to Kant's notion of the transcendental unity of apperception explained in the Critique of Pure Reason. This paper argues that although Fichte and Kant agree on (1) the active nature of the pure I, (2) the distinction between pure and empirical apperception, and (3) skepticism concerning the possibility of theoretical knowledge of any positive (i.e., noumenal) content of the pure I, their respective notions of pure apperception differ in that Kant affirms the conceptual priority of the pure I to its objects while Fichte denies the same. Fichte's departure from Kant on this point foreshadows many later recognition theories of consciousness, e.g., those of Hegel and Marx.展开更多

Surveying Italian professionals, we do not only reveal typical gender differences but also detect divergence to their German counterparts. While disclosing Italian professionals' overly positive self-assessment in general, we find evidence for male overconfidence in particular--though without being accompanied by excessive control illusion of the own information level. Asset managers' risk taking reveals further differences: Italian female professionals do not only assess themselves as more risk averse than their male colleagues, they also prefer a more passive portfolio management compared to the level they are allowed to. Moreover, in a tournament scenario near the end of the investment period female asset managers do not try to become the ultimate top performer when they have outperformed their peer group so far. However, in case of underperformance, the risk of deviating from the benchmark makes especially female professionals willing to seize a chance of catching up. Overall, compared to their German counterparts, we find Italian asset managers to be slightly more risk averse. Matching bounded former results on Italian mutual funds, we discuss interdependencies as well as impact of our findings at the individual asset managers' level on trading activity, management style and performance.展开更多

In this paper, I argue that Herbert Simon's notion of "satisficing" provides a formally well-developed and empirically well-established theory of rationality that fits well with Kuhn's general characterization of science. I start by considering two rival interpretations of the problem of Kuhnian rationality and introduce Simon's notion of satisficing. In Section 3, I show how satisficing can be used to interpret paradigm, change, rational theory-choice, relativism, and progress. On this account, Kuhnian scientists are not irrational. Rather they employ the same computational mechanism which allows humans to play chess.展开更多

Their work has served to connect familiar empiricist approaches to thought and reason with contemporary cognitive psychology and neuroscience. The work of Prinz is of special philosophical significance since it aims to bring together the work of neo-empirically minded theorists in the cognitive and neuro-sciences with main themes found in contemporary philosophical theories of intentionality and reference. In this paper, I examine Prinz's efforts to synthesize a neo-empiricist theory of concepts with contemporary semantic theories of reference and intentionality. In part one, I analyze Prinz's approach in some depth. In part two, I raise a question concerning the origins of intentionality.

Individual differences among patients in terms of their health, illness, social classes and cultural background which lead to different needs emphasize on providing individualized care. And it is strongly related to postoperative care satisfaction. In fact, it tailored nm,ning activities with unique peculiarity of each patient. Actually, it changes all standardized nursing procedures and activities. We aimed to look into the differences between those two types of nursing application in postanesthesia care unit (PACU), affect postoperative care satisfaction in the research. Methods: We conducted a prospective control study that included 325 patients ,randomly divided into two groups: Individualized nursing care group and ordinary nursing care group, undergoing general anesthesia. The 2 groups of patients were similar in respect to gender distribution, age, and type of surgery and had been admitted into the PACU after elective surgery. Data was collected by interviewing with patients using Satisfaction Questionnaire (North Health Service Hospital Consumer Assessment Works by and service systems (H C A H P S) in patients over Meaning of the questionnaire Chinese Translation Version ) , after assessing its content validity and reliability with Chronbach's alpha method. Using SPSS ver. 17 to analysis data .Results: General information on the two groups were no statistically significant differences (P〉 0. 05). Individualized nursing care group (98.2%) compared with the ordinary nursing care group satisfaction (92%) significantly increased (P 〈0. 01). Conclusions: Deployment of individualized nursing care in PACU can significantly improve postoperative satisfaction compared to ordinary nursing care.展开更多

It is found that the ideal number of children for the Chinese trended downwards from 1980, but since 2000 the average number has remained basically stable at 1.6 to 1.8. In the 1980s, people's fertility levels were higher than their fertility intentions. With economic and educational progress in China, both fertility levels and fertility intentions showed a downward trend, with the former declining faster than the latter. Since 1990, people's fertility levels have been lower than their fertility intentions; that is, their actual number of children has been less than their ideal number. This provides an empirical basis for examining the changes in China's fertility intentions and fertility levels.展开更多

Even a s...Recent studies have shown that major nominally anhydrous minerals in the Earth's mantle, such as olivine, pyroxene and garnet, can incorporate considerable amounts of water as structurally bound hydroxyl. Even a small amount of water is present in mantle minerals, it can strongly affect a number of physical properties, including density, sound velocity, melting temperature, and electrical conductivities. The presence of water can also influence the dynamic behavior, lead to lateral velocity heterogeneities, and affect the material circulation of the Earth's deep interior. In particular, seismic studies have reported the existence of low-velocity zones in various locations of the Earth's upper mantle and transition zone, which has been expected to be associated with the presence of water in the region. In the past two decades, the effect of water on the elasticity and sound velocities of minerals at relevant pressure-temperature(P-T) conditions of the Earth's mantle attracted extensive interests. Combining the high P-T experimental and theoretical mineralogical results with seismic observations provides crucial constraints on the distribution of water in the Earth's mantle. In this study, we summarize recent experimental and theoretical mineral physics results on how water affects the elasticity and sound velocity of nominally anhydrous minerals in the Earth's mantle, which aims to provide new insights into the effect of hydration on the density and velocity profile of the Earth's mantle, which are of particular importance in understanding of water distribution in the region.展开更多

Driver behavior has been considered as heterogeneous and inconsistent. Most traffic papers in the literature just discussed heterogeneous driver behavior, to our best knowledge. Two truncated Caussian distributions are used to model heterogeneous and inconsistent driver behavior, respectively. The physical meanings of two truncated distributions are indicated. This method may help enhance a better understanding of driver behavior at roundabout traffic, and even possibly provide references for roundabout design and management.展开更多
文摘Amid the recent global upsurge of studies on the philosophy of emotion, a reinterpretation of traditional Confucian philosophy, especially Mencius's ideas on the siduan (Four Original Sources) of morality, may shed new light on the subject in comparative philosophy. This paper probes the structure of moral feeling and reason described by Mencius's from five perspectives: (1) In view of the relationship between feeling and reason, is it better to use the expression "siduan" or the expression "sixin (Four Heart-minds)"? (2) In view of dispositional feeling, what are the four original sources? (3) In view of moral feeling, what are the structural order of the four sources and the corresponding procedure of reasoning of four heart-minds of Humanity?

The author concludes that Mencius's thought on moral feeing has a global value and cross-cultural significance, and that Chinese wisdom is more than regional but universally applicable. The structure of moral feeling and reason that Mencius identified is in accordance with the principles ofzhiliang (grasping the two poles of the beginning and the end) and yongzhong (emloying the middle). The principles ofzhiliang and yongzhong are true universal wisdoms of Confucianism, which should be rekindled today. From a practical point of view, "the Way begins from moral feelings," and Confucius and Yah Hui's seeking the simple, virtuous life is an ideal model of emotional well-being.

文摘Fichte's various articulations of the Wissenschaftslehre ("theory of scientific knowledge") are self-conscious attempts to systematize Kant's critical philosophy.

It is found that the ideal number of children for the Chinese trended downwards from 1980, but since 2000 the average number has remained basically stable at 1.6 to 1.8. In the 1980s, people's fertility levels were higher than their fertility intentions. With economic and educational progress in China, both fertility levels and fertility intentions showed a downward trend, with the former declining faster than the latter. Since 1990, people's fertility levels have been lower than their fertility intentions; that is, their actual number of children has been less than their ideal number. This provides an empirical basis for examining the changes in China's fertility intentions and fertility levels.

文摘Recent studies have shown that major nominally anhydrous minerals in the Earth's mantle, such as olivine, pyroxene and garnet, can incorporate considerable amounts of water as structurally bound hydroxyl. Even a small amount of water is present in mantle minerals, it can strongly affect a number of physical properties, including density, sound velocity, melting temperature, and electrical conductivities. The presence of water can also influence the dynamic behavior, lead to lateral velocity heterogeneities, and affect the material circulation of the Earth's deep interior. In particular, seismic studies have reported the existence of low-velocity zones in various locations of the Earth's upper mantle and transition zone, which has been expected to be associated with the presence of water in the region. In the past two decades, the effect of water on the elasticity and sound velocities of minerals at relevant pressure-temperature(P-T) conditions of the Earth's mantle attracted extensive interests. Combining the high P-T experimental and theoretical mineralogical results with seismic observations provides crucial constraints on the distribution of water in the Earth's mantle. In this study, we summarize recent experimental and theoretical mineral physics results on how water affects the elasticity and sound velocity of nominally anhydrous minerals in the Earth's mantle, which aims to provide new insights into the effect of hydration on the density and velocity profile of the Earth's mantle, which are of particular importance in understanding of water distribution in the region.

文摘In this paper a cellular automaton model is proposed to describe driver behavior at a single-lane urban roundabout. Driver behavior has been considered as heterogeneous and inconsistent. Most traffic papers in the literature just discussed heterogeneous driver behavior, to our best knowledge. Two truncated Caussian distributions are used to model heterogeneous and inconsistent driver behavior, respectively. The physical meanings of two truncated distributions are indicated. This method may help enhance a better understanding of driver behavior at roundabout traffic, and even possibly provide references for roundabout design and management.
