The rootstock species, Solanum melongena cv Black Beauty, Solanum lycopersicum cv Akash and Solanum nigrum (bitter gumma), reportedly salt-tolerant, were evaluated for their graft compatibility with Capsicum chinense cv Scotch Bonnet. Grafted and non-grafted plants were grown for three weeks under greenhouse conditions. Graft compatibility was determined by the regeneration of vascular bundles across the graft interface and vegetative growth parameters. The results showed that the highest survival percentage (100%) was obtained in the Scotch Bonnet/Black Beauty heterografts and the lowest (16%) was obtained in the Scotch Bonnet/bitter gumma heterografts. Vascular regeneration across the graft interface was seen in Scotch Bonnet autografts and heterografts with Black Beauty. Graft incompatibility observed in heterografts on Akash and bitter gumma rootstocks could be attributed to the presence of a necrotic layer at the graft interface. In conclusion, progressive scion growth and development and the regeneration of vascular bundles across the graft interface are effective in determining graft compatibility between Scotch Bonnet and selected solanceous species. This suggests that Scotch Bonnet can be cultivated under saline growing condition.展开更多

The test has also been utilized in academia to enhance instructor's knowledge of the different learning styles and thus allows them to develop strategies to increase students' learning. The test is a forced-choice self-reporting exam comprised of 126 questions. Based on Jung's theory of personality type, the test seeks to categorize personality types into 16 discrete groups based on the four preference poles (Myers, 1962). The poles are based on the preference for: (1) introversion (I) or extroversion (E); (2) sensing (S) or intuition (N); (3) thinking (T) or feeling (F); and (4)judging (J) or perception (P). Laribee (1994) studied American accounting students and found that certain personality traits were over represented in upper-level accounting courses, while Macdaid, McCaulley, and Kainz (1986) found that the same personality trait groups were over-represented in the profession. Oswick and Barber (1998), however, found no significant relationship between the grade earned in an introductory accounting course and the personality traits as identified by the MBTI with 344 UK-based accounting students. This study investigates the relationship between a student's academic success in a financial accounting principles course and the MBTI personality type indicators. The type distribution of 59 historically black colleges and universities' (HBCU) business administration majors was analyzed and separated into two groups. The groups were then tested to determine if there was a significant difference in the mean grade of the groups in accounting principles.展开更多

This article is part of the Project "Education of the Eye" which introduces the training of the eye as a strategy to understand the architectural forms characterizing the volumetric space (architectural, urban and landscaping), through the polyhedra and their relationships.

In this context, we first present a general solution representing a Noether symmetry vector subject to differential constraints satisfied by the general plane symmetric non-static metric. We then use a class of plane symmetric non-static metrics obtained by Feroze et al. and discuss, in each case, Noether conservation laws in comparison with Killing symmetries.展开更多

Consistent individual dif ferences in behavior have been found across taxa, and have been shown to influence a range of ecological processes. The role of personalities in sexual selection has been considered, and examples exist that show selection for personality traits with both assortative and disassortative mating patterns between personality types. One overlooked aspect of the personality and sexual se lection literature is the potential for personalitysignaling interactions, specifically with complex signaling. Complex signaling is a diverse topic in itself, and in short, consists of multiple signals within one or more modalities that interact to elicit a receiver response. Research into complex signaling has been thorough, although at times studies discover complex signaling systems that fail to fit into one of the existing hypotheses in the literature. Here, we argue that personalities may interact with complex signal ing, which should be considered by researchers of both personality and sexual selection and communication. We describe several ways in which personalitycomplex signaling interactions could affect both the signaler and receiver, and the way in which they may drive personalityspecific signals as well as receiver preferences. Finally, we discuss how considering personality in com plex signaling studies may inform theory as well as improve the ability of researchers to accurately describe its function.展开更多
