The impact of training on virtual team effectiveness was assessed in five areas: communication, planning tasks and setting goals, solving problems and making decisions, resolving conflict, and responding to customer requirements. A 12-page survey was developed exploring all aspects of virtual teams. 180 surveys were distributed, 52 were returned representing 43 companies. Training led to higher effectiveness in planning tasks and setting goals, solving problems and making decisions, and conflict resolution, but not in communication and responding to customer requirements. Training may not solve all the problems that virtual teams will encounter; however, training will make the challenges easier to handle.

This dissertation is a pooled time series, cross-sectional, quantitative study of the impact of international financial transfer on the level of democracy. The study covers 174 developed and developing countries from 1976 through 1994. Through evaluating the democracy and democratization literature and other studies, the dissertation develops a theory and testable hypotheses about the impact of the international variables foreign aid and foreign direct investment on levels of democracy. This study sought to determine whether these two financial variables promote or nurture democracy and if so, how? A pooled time-series cross-sectional model is developed employing these two variables along with other relevant control variables. Control variables included the presence of the Cold War and existence of formal alliance with the United States, which account for the strategic dimension that might affect the financial transfer - level of democracy linkage. The model also includes an economic development variable (per capita Gross National Product) to account for the powerful impact for economic development on the level of democracy, as well as a control for each country's population size. By addressing and the inclusion of financial, economic, strategic, and population size effects, I consider whether change in these variables affect the level of …

The distributional properties of improvement-over-chance, I, effect sizes derived from linear and quadratic predictive discriminant analysis (PDA) and from logistic regression analysis (LRA) for the two-group univariate classification were examined. Data were generated under varying levels of four data conditions: population separation, variance pattern, sample size, and prior probabilities. None of the indices provided acceptable estimates of effect for all the conditions examined. There were only a small number of conditions under which both accuracy and precision were acceptable. The results indicate that the decision of which method to choose is primarily determined by variance pattern and prior probabilities. Under variance homogeneity, any of the methods may be recommended. However, LRA is recommended when priors are equal or extreme and linear PDA is recommended when priors are moderate. Under variance heterogeneity, selecting a recommended method is more complex. In many cases, more than one method could be used appropriately.

The purpose of the study was to investigate the perceptions of job satisfaction as defined by management and nonmanagement employees and to compare both parties' perceptions of organizational benefits to a list prepared by the organization's benefit personnel. Turnover is costly to the organization, both in money and in the impact it has on those individuals remaining with the organization. Every effort should be undertaken to reduce the amount of turnover within the organization. A contributing factor leading to turnover may be a gap between what the employees believe is important to them and what management believes is important to the employees. The boundaries of the gap need to be identified before any effort can be made to reduce or bridge the gap. Once the boundaries are identified, policies can be analyzed and the possibility of reducing the gap investigated. Management as a whole must be aware of the needs and wants of their employees before any attempt to develop a retention strategy is undertaken. This knowledge can be acquired only through two-way communication with the employee. The communication process includes the simple process of asking employees for this information and then listening to how they respond. This study suggests …

Conducting research, evaluating research, and publishing scholarly works all play an extremely prominent role for university faculty members. Tenure and promotion decisions are greatly influenced by the perceived value of publications as viewed by members of faculty evaluation committees. Faculty members seeking tenure may be limited to publishing in a limited group of journals perceived to be valuable by members of an academic committee. This study attempted to determine the value of various kinds of periodicals (journals, magazines, and e-journals), based on three principal criteria, as perceived by professionals (university faculty, K-12 practitioners, and corporate trainers) in the educational/instructional technology (E/IT) field. The criteria for journal evaluation were Academic Prestige, General Reading, and Classroom Use. The perceived value of journals based on each criterion was compared to determine any significant differences. Members of the Association for Educational Communications and Technology (AECT) were asked to rate 30 journals in the E/IT field using the three criteria. Statistically significant differences were found among ratings in 63% of the journals. The statistical analyses indicated that differences in the perceived value of journals among E/IT professionals across the three criteria (Academic Prestige, General Reading, and Classroom Use) were statistically significant. It is also noted …

This Study examines the grades of students using study skill methods and those who do not. The experiment consists of giving the treatment group the opportunity to use well- known study techniques. The Control group could only read the material. Both groups were given ten minutes to read a pre-selected text. The text consisted of an 1,807 word lesson on the, "Technical Training Management System." Each group was given five minutes to take a twenty item quiz. Fifty-five students in the control group were limited to only reading the material. Fifty-six students in the treatment group could choose between highlighting, note-taking, and underlining. The results of the test scores were compared using a t - test for dependent samples. One week later, the same students in each group were re-tested, using the same quiz they had taken earlier. Students had five minutes to review study material. Study material for the treatment group included the same material they had annotated earlier. The Results from each group wascompared. Efforts were made to avoid potential flaws in previous studies, thereby producing more viable results. Results of this study indicate there is no significant difference between the grades of students who use the aforementioned …

The Latin Mass is a musical composition in five movements, scored for large choir, standard orchestra, and two soloists. The movements are the standard parts of the Roman Catholic Mass Ordinary. The language is set mainly in Latin with two exceptions: the Kyrie movement is set in Greek (which is the standard Roman Catholic setting), and the Credo is simultaneously recited in English and sung in Latin. The work is scored using conventional notation techniques and employs rather conservative technical demands on both the choir and orchestra. No extended techniques are required of any of the performers. It is set in a modal harmonic language.

The fractal operators discussed in this dissertation are introduced in the form originally proposed in an earlier book of the candidate, which proves to be very convenient for physicists, due to its heuristic and intuitive nature. This dissertation proves that these fractal operators are the most convenient tools to address a number of problems in condensed matter, in accordance with the point of view of many other authors, and with the earlier book of the candidate. The microscopic foundation of the fractal calculus on the basis of either classical or quantum mechanics is still unknown, and the second part of this dissertation aims at this important task. This dissertation proves that the adoption of a master equation approach, and so of probabilistic as well as dynamical argument yields a satisfactory solution of the problem, as shown in a work by the candidate already published. At the same time, this dissertation shows that the foundation of Levy statistics is compatible with ordinary statistical mechanics and thermodynamics. The problem of the connection with the Kolmogorov-Sinai entropy is a delicate problem that, however, can be successfully solved. The derivation from a microscopic Liouville-like approach based on densities, however, is shown to be impossible. …

The study investigated the relative effectiveness of different proportions of time spent on physical and mental practice, in the context of a music performance of a tonal pattern over harmonic progressions of two difficulty levels. Using a sampling without replacement procedure, sixty undergraduate students were assigned to four practice groups partially blocked for musical instrument. The groups included a physical practice group, a mental practice group and two combined mental and physical practice groups in the proportions of (a) 66% physical and 33% mental, and (b) 33% physical and 66% mental. Each subject performed a pretest, a 3 minute practice session, and a posttest on both harmonic progressions. Presentation of the harmonic progressions were counterbalanced to control for practice effects All pre- and posttests were recorded and scored according to number of note errors. An ANCOVA procedure using pretest scores as covariates revealed that: (a) there were no differences between the different practice groups on the measure of note errors, (b) there was a significant difference between the two harmonic progressions on the measure of note errors, such that performance on the easy progression was significantly better than performance on the hard progression, and (c) there was a significant interaction …

Attrition rates among students in music teacher training programs have contributed to a shortage of qualified music teachers for the nation's schools. The purpose of this study was to investigate the predictive relationship of academic variables in three different learning environments and the intent of a select population of music education majors to leave the degree program. The study drew upon the work of Tinto, Bean and Astin to form a theoretical foundation for examining variables unique to student withdrawal from the music education degree plan. Variables were examined within the context of three different learning environments: (1) applied lessons, (2) ensembles and (3) non-performance courses. Participants were 95 freshmen and sophomore music education majors at a public university who were enrolled in the music education degree program during the spring semester, 2002. Data included participant responses on the Music Student Inventory (MSI), a questionnaire developed specifically for the study, and grade data from university records. Independent variables in the study included participants' perceptions of (1) Ensemble experiences, (2) Applied lesson experiences, (3) Non-performance music course experiences, (3) Course requirements, and (4) Performance growth. Additional variables included: (1) Ensemble placement, (2) Course grades for music theory, applied lessons and aural …

Symmetrical cage-annulated podands were synthesized via highly efficient synthetic strategies. Mechanisms to account for the key reaction steps in the syntheses are proposed; the proposed mechanisms receive support from the intermediates that have been isolated and characterized. An unusual complexation-promoted elimination reaction was studied, and a mechanism is proposed to account for the course of this reaction. This unusual elimination may generalized to other rigid systems and thus may extend our understanding of the role played by the host molecules in "cation-capture, anion-activation" via complexation with guest molecules. Thus, host-guest interaction serves not only to activate the anion but also may activate the leaving groups that participate in the complexation. Complexation-promoted elimination provides a convenient method to desymmetrize the cage while avoiding protection/deprotection steps. In addition, it offers a convenient method to prepare a chiral cage spacer by introducing 10 chiral centers into the host system in a single synthetic step. Cage-annulated monocyclic hosts that contain a cage-butylenoxy spacer were synthesized. Comparison of their metal ion complexation behavior as revealed by the results of electrospray ionization mass spectrometry (ESI-MS), alkali metal picrate extraction, and pseudohydroxide extraction with those displayed by the corresponding hosts that contain cage-ethylenoxy or cage-propylenoxy spacers reveals …

The purpose of this study was to determine if parents trained in the Landreth Filial Therapy Model could demonstrate child-centered play therapy skills as effectively as graduate play therapy students who completed an Introduction to Play Therapy course. The participants in both the parent group and the graduate student group were videotaped in play sessions with children pre- and post-training in order to measure change in adult empathic behavior as defined on the Measurement of Empathy in Adult-Child Interaction (MEACI). The specific skills measured in this study were (a) communicating acceptance to the child, (b) allowing the child to direct his or her own play during the play sessions, (c) demonstrating appropriate levels of involvement in the child's play, and (d) demonstrating empathic behavior toward the child. The Landreth Filial Therapy Model is a training system that utilizes both didactic and dynamic means to train parents and other paraprofessionals to be therapeutic agents of change with children. Parents are taught child-centered play therapy skills to use in weekly home play sessions with their children in order to strengthen the emotional bond between parent and child. The Introduction to Play Therapy course is a graduate-level counseling course at the University of …

The purpose of this study was to investigate the characteristics and means of Katinka Dániel's interpersonal influences through the perceptions of 20 selected students, protégés, and colleagues, and to study the behavioral and attitudinal changes they attributed to her influence. A case study design and structured interview questionnaire were used to study four variables coming from the social sciences' literature on influence: legitimate authority, attractiveness, expert authority, and trustworthiness. Responses were qualitatively analyzed to determine the role those variables played in Dániel's interpersonal influence. All interviewees were music teachers who used the Kodály method in their teaching and have studied or worked with Dániel. Two images of Dániel emerged from the interviews. The first, a business-like image, emanated from Dániel's work in the classroom, and the second, a maternal image, came from personal relationships with her students and associates. Attractiveness (defined as a willingness to respond positively to the requests of an influential person because one respects that individual and wants to obtain that person's approval) proved to be the principal characteristic of influence, followed by legitimate authority, then expertise. Trustworthiness played a lesser role. The greatest effect of Dániel's influence was on the interviewees' teaching. Among the factors interviewees …

The Light is a twenty-four minute composition for two narrators and chamber orchestra. The two narrators perform the roles of the Apostle John and Moses. After an overview of the piece and a brief history of pieces incorporating narrators, the essay focuses on my compositional process, describing how orchestration, drama, motive, and structure work together in the piece. The Light is organized as a series of five related scenes. In the first scene, God creates light. In the second scene, God places Adam and Eve into the Garden of Eden to tend it, allowing them to eat from any tree except the tree of the knowledge of good and evil. The serpent appears, Adam and Eve succumb to his evil influence, and God banishes them from the Garden of Eden. Many generations have passed when Scene Three begins. Moses relates a story from Israel's journey in the wilderness after leaving Egypt. The people had become frustrated with Moses and with God. When God sent serpents among them as punishment, they appealed to Moses to pray for them. God's answer was for Moses to make a bronze serpent and place it on a pole. Whoever looked at the serpent would live. …

The current study examined the effects of acculturative processes on the self-report of behavioral problems in Hispanic children ages 11-14. Acculturation was measured by the Acculturation Rating Scale for Mexican Americans-II (ARSMA-II) (ã Sage Publications, Thousand Oaks, CA, www.sagepub.com) (Cuellar, Arnold, and Maldonado, 1995) and the self-report of behavioral symptoms was assessed using the Youth Self-Report (ã T.M. Achenbach, Burlington, VT, www.aseba.com) (Achenbach, 1991). It was hypothesized that while both the linear and orthogonal categories of acculturation would account for a significant proportion of the variance in behavior problems in this age group, the orthogonal model would account for a larger proportion of variance due to its multidimensional nature. As well, it was hypothesized that the experimental Marginalization scales of the ARSMA-II would be predictive of behavioral problems. Multivariate analysis of variance was used to test these hypotheses and results were non-significant for the linear, orthogonal, and marginalization categories. The effects of the ethnic/cultural homogeneity of the region from which the sample was drawn, the buffering of social support, and the developmental aspects of ethnic identity are discussed as factors which may have influenced the potential impact of acculturative stress on psychological and behavioral functioning.

jn4.gesture is an interactive multimedia composition for dancer and computer designed to extend the possibilities of artistic expression through the use of contemporary technology. The software produces the audiovisual materials, which are controlled by the movement of the dancer on a custom rug sensor. The software that produces the graphic and sonic material is created using a modular design. During run-time, the software's modules are directed by a scripting language developed to control and adjust the audiovisual production through time. The visual material provides the only illumination of the performer, and the projections follow the performer's movements. The human form is isolated in darkness and it remains the focal point in the visual environment. These same movements are used to create the sonic material and control the diffusion of sound in an eight channel sound system. The video recording of the performance was made on April 22, 2002. The work was produced in a specialized performance space using two computer projectors and a state of the art sound system. Arleen Sugano designed the costumes, choreographed and performed the composition in the Merrill Ellis Intermedia Theatre (MEIT) at the University of North Texas. The paper focuses on the design of the …

Nanocomposites with expandable smectites such as montmorillonite layered silicates (MLS) in polymer matrices have attracted extensive application interest. Numerous MLS concentrations have been used with no particular justification. Here, we investigate the effects of MLS dispersion within the matrix and on mechanical performance. The latter is resolved through a three-prong investigation on rate dependent tensile results, time dependent creep results and the influence of a sharp notch in polypropylene (PP) nanocomposites. A fixed concentration of maleated polypropylene (mPP) was utilized as a compatibilizer between the MLS and non-polar PP. Analysis of transmission electron micrographs and X-ray diffraction patterns on the surface and below the surface of our samples revealed a unique skin-core effect induced by the presence of clay. Differential scanning calorimetric and polarized optical microscopic examination of spherulites sizes showed changes in nucleation and growth resulting from both the maleated PP compatibilizer and the MLS. These structural changes resulted in a tough nanocomposite, a concept not reported before in the PP literature. Nonlinear creep analysis of the materials showed two concentrations 3 and 5 % wt of PP, which reduced the compliance in the base PP. The use of thermal wave imaging allowed the identification of ductile failure among …

It is known that there are nonlinear wave equations with localized solitary wave solutions. Some of these solitary waves are stable (with respect to a small perturbation of initial data)and have nonzero spin (nonzero intrinsic angular momentum in the centre of momentum frame). In this paper we consider vector-valued solitary wave solutions to a nonlinear Klein-Gordon equation and investigate the behavior of these spinning solitary waves under the influence of an externally imposed uniform magnetic field. We find that the only stationary spinning solitary wave solutions have spin parallel or antiparallel to the magnetic field direction.

Robert Schumann's D-minor Symphony endured harsh criticism during the second half of the nineteenth century because of misunderstandings regarding his compositional approach to the genre of the symphony; changes in performance practices amplified the problems, leading to charges that Schumann was an inept orchestrator. Editions published by Clara Schumann and Alfred Dörffel as well as performing editions prepared by Woldemar Bargiel and Gustav Mahler reflect ideals of the late nineteenth century that differ markedly from those Schumann advanced in his 1851 autograph and in the Symphony's first publication in 1853. An examination of the manuscript sources and the editions authorized by Schumann reveals that he imbued the Symphony with what he called a "special meaning" in the form of an implied narrative. Although Schumann provided no written account of this narrative, it is revealed in orchestrational devices, particularly orchestration, dynamics, and articulation, many of which have been either altered or suppressed by later editors. A reconsideration of these devices as they are transmitted through the authorized sources permits a rediscovery of the work's special meaning and rectifies long-standing misperceptions that have become entrenched in the general literature concerning Schumann in general and the D-minor Symphony in particular.

This dissertation addresses the delicate problem of establishing the statistical mechanical foundation of complex processes. These processes are characterized by a delicate balance of randomness and order, and a correct paradigm for them seems to be the concept of sporadic randomness. First of all, we have studied if it is possible to establish a foundation of these processes on the basis of a generalized version of thermodynamics, of non-extensive nature. A detailed account of this attempt is reported in Ignaccolo and Grigolini (2001), which shows that this approach leads to inconsistencies. It is shown that there is no need to generalize the Kolmogorov-Sinai entropy by means of a non-extensive indicator, and that the anomaly of these processes does not rest on their non-extensive nature, but rather in the fact that the process of transition from dynamics to thermodynamics, this being still extensive, occurs in an exceptionally extended time scale. Even, when the invariant distribution exists, the time necessary to reach the thermodynamic scaling regime is infinite. In the case where no invariant distribution exists, the complex system lives forever in a condition intermediate between dynamics and thermodynamics. This discovery has made it possible to create a new method of analysis …

The purpose of this study was to determine the core skills/methods and practicum experiences play therapy experts and professors believe to be essential in the education of the beginning play therapist in the specific areas of theory and history, terms, organizations, authors who have contributed to the field, methods, skills, training in special populations, practicum experience, and advanced skills. Two questionnaires were used to obtain opinions from play therapy experts and play therapy instructors. The first questionnaire was sent to twelve play therapy experts to obtain their opinions on the core curriculum and experiences necessary for training a play therapist in an introductory play therapy class, practicum experience, and advanced play therapy training. Frequencies and means were obtained and used to delete and add items for Questionnaire II. Questionnaire II was sent to 180 play therapy professors. Fifty play therapy professors returned the instrument. The ratings on Questionnaire II given by the professors were used to provide curriculum guidelines for developing a play therapy program. This program includes an introduction to play therapy course, play therapy practicum experiences, and advanced skills and advanced practicum experiences.

This study was designed to determine the effectiveness of short-term child-centered play therapy training with school counselor and teachers in Israel. A short-term child-centered play therapy course is an intervention that focuses on changing trainees attitudes and beliefs towards children while teaching them child-centered play therapy theory and skills. The experimental group, consisting of 18 volunteer school counselors and teachers in Israel received a total of 15 hours of child-centered play therapy didactic training with a variety of learning experiences. The control group consisted of 15 volunteer school counselors and teachers in Israel. The control group did not receive any training. All participants completed the Play Therapy Attitude-Knowledge-Skill Survey (PTAKSS) before and after the training as a means of measuring change in attitude, knowledge and skill. A second purpose of this study was to compare the effectiveness of short-term child-centered play therapy training with a comparison group semester long child-centered play therapy training course at the University of North Texas. An analysis of covariance revealed statistically significant positive increase in Knowledge subscale as compared to the control group. However the differences between the experimental and the control group were not significant on the participant's total score on the PTAKSS, their …

The purpose of this study was to assess the benefits that selected adult piano students reported receiving from their study. Adult piano students (N = 711) from 24 states representing all geographic regions of the U.S. each completed a questionnaire containing 31 individual benefit items. These benefits were organized into 3 categories: Personal, Skill, and Social/Cultural. The demographic characteristics of the study population were consistent with the findings of other adult music research. Students indicated the existence (yes or no) of each benefit and rated the importance of existing benefits on a scale of 1-10. The category of Skill Benefits was the most agreed upon and highest rated category in the study, with over 90% agreement for each of the 7 Skill Benefits. The 14 Personal Benefits were also rated highly, particularly benefits related to self-actualization and fun. Self-related Personal Benefits were rated moderately, while more introverted Personal Benefits such as Imagination/Creativity, Spirituality, and Aesthetic Appreciation were lower rated benefits. The 10 Social/Cultural benefits were the lowest rated and least important benefits in the study. The most agreed upon benefits were Skill Improvement, Musical Knowledge, Musicianship, Accomplishment, Skill Refinement, Technique, Play/Fun, Escape from Routine, and Music Listening. The highest rated …

Walt Whitman's poetry continues to inspire composers of choral music, and the growing collection of musical settings necessitates development of a standard evaluative tool. Critical evaluation of the musical settings of Whitman's work is difficult because the extensive body of verse is complex and of uneven quality, and lack of common text among compositions makes comparison problematical. The diversity of musical styles involved further complicates the issue. Previous studies have focused on either ideology or style, but none have united the two critical approaches, thus restricting potential for deeper understanding of the music. This study proposes an approach to critical evaluation of Whitman settings that applies hermeneutics, or a blend of analysis and criticism, to the process. The hermeneutic approach includes an examination of the interrelationship between musical form and style and the composer's ideology, which is revealed through his/her treatment of Whitman's poetry and analyzed in light of cultural influences. Lowell Liebermann (b. 1961) has composed a large scale choral/orchestral setting of Whitman texts in his Symphony No. 2, opus 67 (1999). The selection, placement, and treatment of poetry in Symphony No. 2 provide a window into the composer's mind and his place in the current musical climate. Liebermann's …
