As the title of the work suggests, Burn brings to mind the qualities, characteristics and properties of fire: its volatile, destructive and unpredictable nature, and its often-overlooked sublime and evanescent states. Although I did not set out to programmatically depict the element in Burn, fire provides a metaphor for the compositional process. My objective was to compose a work that is harmonically and motivically rich, and where colour and character are of absolute importance. In turn, the work is explosive and unrelenting, with contrasting moments of subtler music. The complex and volatile personality of fire takes form right from the dramatic and combustible opening of Burn, through to the kaleidoscopic and mercurial textures of its developmental sections, its slow but catastrophic middle section, and its remorseless ending. And like the prodigiously agile nature of this element, I wanted to write a work that is engaging and virtuosic for its players. Burn is a single-movement work cast in three dramatic sections. The opening, spanning from mm. 1-24, establishes the musical material and sets the tone for the work. The music of the introduction gives way, at m. 25, to a developmental section, where varied forms of the introduction appear as structural delineators: mm. 68-71 to close the first part of the development, mm. 98-106 and mm. 131-136. The outer sections of Burn, mm. 1-136 and mm. 188-291, are fast and furious, colourful and nimble, and are similar to each other in character and content. The contrasting middle section, mm. 137-187, gives way to a different music, one that is slow and intense but shares motivic and harmonic attributes with the outer sections. The music climaxes at the return of the Tempo Primo, mm.166-187, with the defining motif of the outer sections superimposed at its original speed over the broad music of the middle section. Burn closes at the end of the third section with a varied return of the introduction.

Recombined Forces, for full orchestra, provides contrast by changing the inner divisions of the whole. These divisions include the gradual separation of the orchestra into different choirs, evolving rhythmic and contrapuntal roles, and the harmonic reordering of one central recurring chord into smaller chords with contrasting characters. The orchestra begins as a whole divided into the traditional choirs, grouped by their physical similarities, and ends as a whole grouped by timbral characteristics. Grouped instruments enter and cutoff together, and play the same contrapuntal lines. Harmonically, the piece progresses through four stages. The recurring total sonority, set class [01234578t], begins as three members of set class [013], becomes three of [016], three of [025], an finally three of [037]. The piece develops by recycling materials rather than by replacing materials, and reveals how subtle changes in organization can lead to vastly different results.

This paper examines the relationship between immigrant-composition and wages of different occupations and different industries in Canada. It reports the effects of change in proportion of immigrants on the wage level in 1996 for both male and female Canadians and immigrants. First all immigrants are considered homogeneous and thereafter they are distinguished according to a wide array of criterion and a full spectrum of results are presented. These results suggest that for immigrants the aggregate relationship of income with immigrant composition is fairly small, unless they are subcategorised into specific groups (e.g. non-white immigrants, immigration after 1990). The corresponding wage penalties for Canadians are more uniform across the different subgroup specifications and decomposition of the data.

Let £f be a complex number in the closed unit disk D , And H be a separable Hilbert space with the orthonormal basis , say ,£`= {e_n:n=0,1,2,¡K}. A bounded operator T on H is called a £f- Toeplitz operator if <Te_(n+1) ,e_(m+1) >=£f<Te_n ,e_m > (where < , > is inner product on H) The L^2 function £p~ £Ua_n e^in£c with a_n=<Te_0 ,e_n> for n>=0 , and a_n=<Te_n ,e_0 > for n<0 is , on the other hand , called the symbol of T The subject arises naturally from a special case of the operator equation S^* AS=£fA+B where S is a shift on H , which plays an essential role in finding bounded matrix (a_ij ) on L^2 (Z) that solves the system of equations {((a_(2i,2j) =p_ij+aa_ij@a_(2i,2j-1) =q_ij+ba_ij )@a_(2i-1,2j) =£h_ij+ca_ij@a_(2i-1,2j-1) =£s_ij+da_ij ) ¢t, for all i ,j belong Z , where (p_ij ) ,(q_ij ) ,(£h_ij ) ,(£s_ij ) are bounded matrices on l^2 (Z) and a ,b ,c ,d belong C . It is also clear that the well-known Toeplitz operators are precisely the solutions of S^* AS=A , when S is the unilateral shift . In this paper , we will determine the spectra of £f- Toeplitz operators with |£f|=1 of finite order, and when the symbols are analytic with C^1 boundary values.

The purpose of this study was to investigate the differences in the academic performance of economically disadvantaged African-American students attending schools with distinct racial composition in selected inner-city Texas high schools based on the information available in the Academic Excellence Indicator System (AEIS) database. The degree to which certain schools’ racial compositions may impact the achievement of economically disadvantaged African-American students was explored. The study was conducted in order examine the academic performance of economically disadvantaged African-American student groups in three large, comprehensive high schools with distinct ratios of school racial compositions. The analyses of student performance data in these three educational settings over three years offers insight into whether school racial composition affects the academic achievement of economically disadvantaged African-American students. A quantitative, two factor factorial (with repeat on the last factor) design was used to answer the questions posed. A mixed-model analysis of variance (ANOVA) was employed to analyze school and student level differences between the percentage of minority students in a school and the academic outcomes. Specifically, the reading and mathematics TAKS scores of economically disadvantaged African-American students from three high schools with distinct ratios of school racial composition were compared and analyzed. The final sample included 428 African-American students. The first school had a racial composition of 80/20, with African-Americans being the minority. The second school had a balanced racial composition (defined as “30/30/30”), and the third school’s racial composition was 30/70, with African-Americans being the majority. The most important finding in this study is that the differences in the reading and math performance of economically disadvantage African-American high school students attending schools with different racial composition are statistically significant. The researcher observed an increase in the average academic performance of African- American students as the concentration of minority students in the schools was reduced. Although the effect of school racial composition was minimal, the findings indicate that (even after controlling the effects of schools and students’ demographic factors by holding these variables constant) reading and math TAKS scores were consistently higher in the 80/20 school than in the 30/30/30 school, followed by the 30/70 school.

The objective of this study was to investigate the role of team sex composition in team training performance and team processes in the context of a complex, psychomotor, information–processing task. With the growing number of women in the workplace, the role of, and implications for, team sex composition is an important research question because there are performance domains, such as psychomotor tasks, where replicable sex differences have been documented. We used 92 four–person teams to investigate the relationship between team sex composition, team declarative knowledge, team–efficacy, team communication, team cohesion, and team performance on a complex, psychomotor, information–processing task. The results indicate that team sex composition was significantly related to team performance and team declarative knowledge. Furthermore, team performance and team declarative knowledge showed significant mean differences across the levels of team sex composition, such that teams with a larger proportion of males had higher scores on each of the variables. As hypothesized, team communication showed an opposite effect where teams with higher proportions of females reported larger amounts of communication, but none of the team sex composition pairwise comparisons were significantly different. The posited relationship between team cohesion and team homogeneity was not supported. Finally, there was no evidence for any of the process variables moderating the relationship between team sex composition and team performance. Team sex composition may be an important variable in training situations where past sex differences have been demonstrated on the performance task of interest. The findings suggest the need to consider instructional design strategies that may mitigate the negative effects of team sex composition on team performance. Future research is needed to determine the extent to which findings from this single study generalize to other psychomotor task domains and how all–female teams will perform under similar circumstances.

Design reuse and effective design integration is an important ways to increase design productivity. It is thus an important subject to develop, integrate and reuse design libraries provided by different designers. In this thesis, we developed software design of an instance graph expansion that can expand attribute composition graph instance from attribute composition graph schema. Designer can then effectively construct design organizations for application designs, and perform design reuse in real designs.
