The dry intrusion and the accompanying downward transport of air with a high value of potential vorticity (PV) are maintained during the precipitation event. As the dry air intrudes down into the warm and moist sector in the lower troposphere, the cold, dry air and the warm, moist air mix with each other, and, as a result, the atmosphere becomes non-uniformly saturated. On the basis of this non-uniform saturation, a new Brunt-Vaisaila frequency (BVF) formula is derived and applied to the precipitation event. It is shown that, compared to the conditions of either a dry or a saturated atmosphere, the BVF in a non-uniformly saturated, moist atmosphere (BVF) may be more appropriate for depicting the atmospheric instability in rainy regions.展开更多

It has received much scholarly prominence in the Western world, and perceived as an emergent art of European origin. What has been given little or no scholarly attention is the African essence of root of conceptual art movement. This article addresses the historical epochs of conceptual art in Africa and delves into the critical question of whether or not conceptual art is an emergent art in Africa. With the help of the images of African artworks, this article attempts to fmd visual answers by examining the art-historical account of the art through visual analysis in simple narrative format in telling the African side of the story. It concludes that the adoration and idolization of Marcel Duchamp as the father of conceptual art is contestable since the art was many centuries old in Africa before the twentieth century artists began to practice it in the West. Duchamp's attempt at dematerialization of art, and showing distaste to the traditional aesthetics of Western art at the time through conceptual exploration had been in practice in African art and, therefore, not an invention.展开更多

This is a positive development that resonates with the democratic dispensations. Despite of some resistance from certain quarters of the society, overall women's presence is becoming acknowledged. This increase has a potential to make a positive impact on peacekeeping missions. Their utility is enhanced by their characteristics that are lamented for their incongruence to combat operations. The constructive and reconciliatory nature of peacekeeping mission makes them an important asset. However, their optimal productivity is threatened by the incessant rape that they experience from both their adversaries and the own force. This creates a stressor that compromises their performance. The situation is aggravated by the lack of support after their ordeal. The organisational culture and leadership are not making women's presence in operations tenable. Their experience post-rape is characterised by rejection and lack of support from the salient others. This situation requires to be changed urgently to provide a sense of security and care for women. Policies and practices need to be modified to allow optimal performance from the most productive group in the military force.展开更多

Blixen-Finecke worldwide fame because the novel caused wide public concern among both critics and readers. The story unfolds a poetic picture which reveals the natural peace and harmony in Africa through the narrative angle of the heroine--Karen Blixen. In Out of Africa, the author, from multipoint viepoints, knits the legendary plot to display a picture of a community with the features of spiritual utopia, which is an ideal place for men to escape from the outside disturbance. The present paper, first, gives a brief introduction to the plot of the story. Then, it discusses the characteristics of spiritual utopian community on the African land from the following three perspectives: Karen Blixen is a pursuer to go after self-integrity so as to protect the harmony of spiritual utopian land in Africa; Africans are the paragons of self-integrity to pursue freedom on their homeland; and the western settlers are the dominators who have lost self-integrity in the spiritual utopian community because they have almost destroyed the ecological and social banlance on African land.展开更多

Catastrophe control based on catastrophe theory is a brand new area for control theory. A certain catastrophe is created at a desired location by appropriate control, which has preferred properties. Washout filter is presented and applied to preserve the original equilibrium of a system. Washout filter aided dynamic feedback controller is developed for the creation of catastrophe, and an example is given to illustrate the process. Catastrophe control may provide a new way of designing warning signals of impending collapse or catastrophe for monitoring and control purposes.展开更多

The characteristic of time structure variation index characteristic was analyzed about gas concentration sequence of three measure points in the NO. 1I 1024 working face. It was found that the value of time variation about three measure points was mostly 1〈δ≤1.5, and gas emission presented consistently strong-clustering state twice, and the value of time variation presented continuous variation state in the active stage of gas concentration. Complex characteristics of the value indicated gas emission was continuously variable in time or space and presented the complex nonlinear characteristics. So the characteristic about gas emission system was correctly depicted and analyzed to gas emission system according to the relation of its state variation and essential of nonlinear system. The result also provided reliable warranty for its continued nonlinear research on gas emission.展开更多

Initially, it is felt as unlimited and indeterminate will power, with the potentiality of multiple choices. Thereafter, reductive deliberation is led by determinism to the final decision, which realises only one of the potential choices. The reductive deliberation phase tries to find out the best alternative and simultaneously satisfying vague motivations, contextual conditions and personal preferences. The essential sense of free will is the introduction of personal preferences, which allows a higher diversity of reactions to vague motivations. With an oversimplified model of determinism as a chain of events, incompatibilists define "free" as "undetermined" so that determinism becomes incompatible with any free choice between alternatives. In consciousness, free will requires a more complex model of network determinism as well as the consideration of unconsciousness as a causal factor. When "free" defined as "undetermined" is applied to the context of consciousness, it should be reinterpreted as "unconscious of being determined" or not aware of underlying determinism. Lacking information on determinism generates a feeling of "free" in consciousness and, therefore, gives the impression of indeterminism. Lacking information may be induced by an uncertain future without determined events--an unconscious past with biological reactions suddenly emerging from the unconsciousness or an unknown present unable to distinguish determinism of complex events. Therefore, at the level of human consciousness, the experience of free will is associated with apparent indeterminism although it is based on unconscious determinism. The concepts of compatibilism and incompatibilism are only two different aspects of the same phenomenon and correspond to consciousness and unconsciousness. Nevertheless, they can be considered together with a free will concept based on relativity depending on two different reference frames--the first person's experience frame or the Laplace's demon frame with knowledge on every molecule of the universe. Only relativity of the free will concept avoids the contradiction between "free" and "unfree" for the same phenomenon and could be a compromise for considering compatibilism and incompatibilism equally.展开更多

This paper explored the narratives of 10 sex trafficked women from a major non-government organization in New Delhi. Qualitative methodology was adopted and data were collected through open-ended unstructured interviews. The victimological paradigm including the Lifestyle Risk Model (LRM) by Van der Hoven and Maree provided the framework to discuss the key issues related to sex trafficking. Psychological experiences such as being abused by husbands, and in some cases, victims' own families; social conditions such as poverty and education; cultural practices such as vulnerability of women and marginalization; and lifestyle risk factors were observed throughout the stories of the victims. Furthermore, shame was found to be the core emotion in the stigmatization process. Limitations and future directions are also discussed.展开更多

The conditions of the CNOP-type precursors are highly likely to evolve into El Nino events in the Zebiak-Cane model. By exploring the dynamic behaviors of these nonlinear El Nino events caused by the CNOP-type precursors, we find that they, as expected, tend to phase-lock to the annual cycles in the Zebiak-Cane model with the SSTA peak at the end of a calendar year. However, E1 Nino events with CNOPs as initial anomalies in the linearized Zebiak-Cane model are inclined to phase-lock earlier than nonlinear E1 Nino events despite the existence of annual cycles in the model. It is clear that nonlinearities play an important role in El Nino's phase-locking. In particular, nonlinear temperature advection increases anomalous zonal SST differences and anomalous westerlies, which weakens anomalous upwelling and acts on the increasing anomalous vertical temperature difference and, as a result, enhances E1 Nino and then delays the peak SSTA. Finally, we demonstrate that nonlinear temperature advection, together with the effect of the annual cycle, causes El Nino events to peak at the end of the calendar year.展开更多

In the application of plea bargaining, comprehensive consideration should be given to multiple values, including efficiency, justice, harmony, and tempering severity with leniency, Plea bargaining should be applied in cases that do not involve a felony, should be based on a determination of the nature of the crime, and should be limited to bargaining over penalties. Plea bargaining agreements are entered into by the procurator and the defendant, and do not extend to the judge.展开更多
