The ideal triple pattern is composed of an equatorially symmetric heat source in the middle and equatoriaUy asymmetric cold forcing in the southeast and northwest. The equatorially symmetric heat source excites low-level cyclonic circulation anomalies associated with Rossby waves in both hemispheres, while the northwest- ern and southeastern equatorially asymmetric cold sources induce low-level anomalous anticyclones associated with Rossby waves in the hemisphere where the forcing source is located. Low-level zonal winds converge toward the heat sources associated with Kelvin and Rossby waves. Due to unequal forcing intensity in the northwest and southeast, atmospheric responses around the equatorially symmetric forcing become asymmetric, and low-level cyclonic circulation anomalies in the Southern Hemisphere become greater than those in the Northern Hemisphere. Ascending (descending) flows coincide with heat (cold) sources, resulting in a double-cell structure over the regions of forcing sources. Ideal triple patterns similar to SSTA patterns associated with La Nina Modoki produce opposite atmospheric responses. The theoretical atmospheric responses are consistent with observed circulation anomalies associated with ENSO Modoki. Therefore, the theoretical solutions can explain the dynamics responsible for atmospheric circulation anomalies associated with ENSO Modoki events.展开更多

The modem universities are the formal social organizations, and that the universities implement the bureaucratic administration has its own rationality which is not negligible. However, the universities are the academic organizations, and their intrinsic attributes, that is, the ambiguity of their goals, the diversified values, and the uncertainty of the processes of their activities and the effects, result in the inevitable limitations in the bureaucratic administration of the universities. Therefore, the improvement of the university bureaucratic administration systems should be implemented based on the inherent logic of the universities.展开更多

Through content analysis, this study examines general requirements, core public relations courses, requirements of public relations programs and strategic communication programs, and optional public relations courses offered by the colleges. The findings of this study reveal that very few public relations programs offer courses involving new media, crisis communication, and PR ethics. In order to keep in touch with the fast-changing public relations landscape, more PR programs should require and integrate new media, crisis communication and ethics courses.展开更多

Of course, exist the sounding to make this work, but not always it is possible to access to sounding data when is necessary, so then, it is important to has others alternatives methods in order to replace it. The troposphere is basically a fluid, susceptible to be studied under the fluid mechanics and thermodynamics of the ideals gases without loss generalities. So, it is possible to study of the atmospheric air like as a continuous perfect gas. These facts are important questions to study the troposphere under the laws and beginning Physics, using its respective equations, in order to get a theoretical model to simulate the behavior of its thermodynamics variables and parameters. Working on this line, it was developed a model in order to simulate the tropospheric pressure variation on the height from its measure on surface data.展开更多

This present study examines how Roberto Rossellini's early neorealist films, Rome, Open City (1945) and Paisan (1946), utilize the emotion of compassion to examine the social and historical significance of women in the postwar Italy. Furthermore, it also focuses on the role of the female protagonists and the compassionate responses they suggest to clarify their position in society. In fact, by depicting the female protagonists as modest dissenter that attempt to perform traditional domestic roles, the director proposes a unique perspective on the conditions and social involvement of women in Italy during that time. Additionally, this study will propose interesting observations on the emotion of compassion itself, and its mechanisms that produce an image of idealized womanhood.展开更多

"China Dream", was the sublimation of university ideological and political education, ever advancing with the time, the "China Dream" tightly integrated into the university ideological and political education, strives to cultivate the endeavor of having both ability and political integrity, and having the national feelings of dedication. Therefore, college ideological and political education work is to "China Dream" as the guider, actively promotes the educational model innovation.展开更多

The talents should qualified with strong professional ability as well as good psychological quality to adapt to the growing challenges, College students, a new generation of young people shouldering the historical mission and the important responsibility of the country, are under the great pressure from family, school and society. All of these will aggravate their negative psychological emotions with the formation of complicated personality, which not only go against the growth of young talent, but also drive hidden troubles to the stability and harmony of the social. Plunging into the students' life and deeply analyzing their psychological characteristics with timely manners of solving psychological problems will accelerate the ideological and political education and promote talents cultivation with more modem intellectuals for our country.展开更多

Without a comprehensive study on the cause of this problem, any prescriptive suggestion or discussion on how to go beyond radicalism is no more than an idealistic path for China's political reconstruction.展开更多
