This research is about the relationship between Nigerian home videos production, women and cultural ideologies. It is general agreed that there is a sexist problem which has dominated the entire mass media. The study researches that an impact assessment of the images of women in Nigerian home videos is designed to examine the sway Nigerian home videos portrayal of women have on women's position and status in the society. The study also investigates the influence of home videos on women's and girl's perception of themselves and its effect on their development potentials. With 300 respondents drawn from a select range of home videos viewers, a survey research was designed using Awka-urban, Capital of Anambra State, Nigeria as the research area and finds a negative perception of women as regards their image portrayal in the home videos by the viewers. However, this image portrayal has a negative effect on the development potentials of women and that of girl child and as well reflects on how women are seen and treated in Nigerian society. 展开更多

The basic concepts about the active structures and some attributes of the modes were presented in paper “Liner Active Structures and Modes]( I) ". The characteristics of the active discrete systems and active beams were discussed, especially, the stability of the active structures and the orthogonality of the eigenvectors. The notes about modes were portrayed by a model of a seven-storeyed building with sensors and actuators. The concept of the adjoint active structure was extended from the discrete systems to the beams that were the representations of the continuous structures. Two types of beams with different placements of the measuring and actuating systems were discussed in detail. One is the beam with the discrete sensors and actuators, and the other is the beam with distributed sensor and actuator function. The orthogonality conditions were derived with the modal shapes of the active beam and its adjoint active beam. An example shows that the variation of eigenvalues with feedback amplitude for the homo-configuration and non-homo-configuration active structures. 展开更多

When painters do self-portraits they often use a photo, a mirror, a portrait done by someone else, or a memory of their own image. Photos are commonly used, and while they make it possible to get the broad outlines, it is difficult to imbue the portrait with life. Jiang’s self- 展开更多
