This study applied the theory and research on ethical practices of successful managers and ethics control mechanisms to identify the ethical climates that result in ethical behaviors in the banking. 141 employees from different banks in Shanghai, China, completed measures of all scales in the survey. The results support the theorizing of the value of well-formed business ethics in the banking in China. The correlation and structural equation analysis suggests that ethical practices of successful managers and ethics control mechanisms of banks reinforce three ethical climates of ‘service’, ‘law and rules’ and ‘caring’ that promote the ethical level of employees, and the independence and instrumental climate on the contrary. This study also found that there are three ethics control mechanisms most commonly used in the banking and ethics-focused reward system is believed to be a mostly effective one by the employees of banking in China.展开更多

The so-called ＂Yellow peril theory＂ and ＂China threat theory＂ have caught on once again. Faced with such frequent trade conflicts, we fall into contemplation. Why did trade conflicts so frequently happen？ Do these conflicts merely remain at the commercial level？ Or, are there any deep-seated conflicts leading to trade conflicts？ What are the root causes of these conflicts？ How to overcome and avoid these conflicts in the future？ With these questions, this paper is designed to inquire into the root cause of trade conflicts and the constructive suggestions to settle trade conflicts from a cultural perspective.展开更多

The acceptable walking access area is determined according to the willingness of passengers to walk who prefer rail transit compared with bus and automobile. Empirical studies were conducted using the survey data of six stations from the rail transit in Nanjing, China. The results indicate that the rail transit is more preferable compared with bus and private automobile in this case when excluding the influence of individual and environmental factors. It is found that passengers tend to underestimate their willingness to walk. The acceptable walking access area of every rail transit station is different from each other. Suburban stations generally have a larger walking access area than downtown stations. In addition, a better walking environment and a scarcer surrounding traffic environment can also lead to a larger walking area. The model was confirmed to be effective and reasonable according to the model validation. This study can be of benefit to the passenger transportation demand estimation in the location planning and evaluation of rail transit stations.展开更多

As a result, many Afi＇ican American women lack knowledge about how to care for their naturally kinky hair because straightened hair has been the standard and norm. Therefore, women wearing natural hair had to seek support and education outside of their immediate community via social networking sites. Through a participatory culture framework via an Afrocentric lens, the results revealed that producers of these sites became the needed support and comfort that the natural hair community was missing. Through communication with these producers and their sites, a space was created where women began to appreciate and love their natural hair.展开更多

Reality is what it is, and it exists independent of the observer. The last Jain Tirthankar Mahaveer suggested that organisms interact with such realities for survival needs and become concerned about the consequences. He suggested a code of conduct for reality-based behaviors to address concerns. Perceptions and impressions provide measures （praman） of information in sense experience, and with other evidence guide choices and decisions to act and bear consequences. Ethical behaviors rooted in reality have desirable consequences, and inconsistent and contradictory behaviors are undesirable consequences. Omniscience （God, Brahm） is discarded as a self-referential ad hoc construct inconsistent and contradictory to real world behaviors. This article is survey of assumptions and models to represent, interpret, and validate knowledge that begins with logical deduction for inference （anuman） based on evidence from sense experience （Jain 2011）. Secular and atheistic thrust of thought and practice encourages reasoning and open-ended search with affirmed assertions and independent evidence. Individual identity （atm） emerges with consistent behaviors to overcome fallibility and unreliability by minimizing doubt （Syad-Saptbhangi Nay）. The first Tirthankar Rishabh Nath （ca. 2700 BC） suggested that the content （sat） of real and abstract objects and concerns during a change is conserved as the net balance of the inputs and outputs （Tatia 1994）. Identity and content of assertions and evidence is also conserved during logical manipulations for reasoning. Each assertion and its negation are to be affirmed with independent evidence, and lack of evidence for presence is not necessarily the evidence for either non-absence or non-existence.展开更多
