Natural Smooth Measures on the Leaves of the Unstable Manifold of Open Billiard Dynamical Systems
In this paper, we prove, for a certain class of open billiard dynamical systems, the existence of a family of smooth probability measures on the leaves of the dynamical system's unstable manifold. These measures describe the conditional asymptotic behavior of forward trajectories of the system. Furthermore, properties of these families are proven which are germane to the PYC programme for these systems. Strong sufficient conditions for the uniqueness of such families are given which depend upon geometric properties of the system's phase space. In particular, these results hold for a fairly nonrestrictive class of triangular configurations of scatterers. digital.library.unt.edu/ark:/67531/metadc278917/
The Rhetoric of Posthumanism in Four Twentieth-Century International Novels
The dissertation traces the trope of the incomplete character in four twentieth-century cosmopolitan novels that reflect European colonialism in a global context. I argue that, by creating characters sharply aware of the insufficiency of the Self and thus constantly seeking the constitutive participation of the Other, the four authors E. M. Forster, Samuel Beckett, J. M. Coetzee, and Congwen Shen all dramatize the incomplete character as an agent of postcolonial resistance to Western humanism that, tending to enforce the divide between the Self and the Other, provided the epistemological basis for the emergence of European colonialism. For example, Fielding's good-willed aspiration to forge cross-cultural friendship in A Passage to India; Murphy's dogged search for recognition of his Irish identity in Murphy; Susan's unfailing compassion to restore Friday's lost speech in Foe; and Changshun Teng, the Chinese orange-grower's warm-hearted generosity toward his customers in Long River--all these textual occasions dramatize the incomplete character's anxiety over the Other's rejection that will impair the fullness of his or her being, rendering it solitary and empty. I relate this anxiety to the theory of "posthumanism" advanced by such thinkers as Marx, Bakhtin, Sartre, and Lacan; in their texts the humanist view of the individual as an autonomous constitution has undergone a transformation marked by the emphasis on locating selfhood not in the insular and static Self but in the mutable middle space connecting the Self and the Other. digital.library.unt.edu/ark:/67531/metadc278990/

A Study of Differences Perceived by Information Systems Professionals in the Systems Development Job Environment Due to the Use of ICASE Technology
Information systems professionals now face the automation of their own work in integrated computer aided software engineering. Organizations need to achieve all the leverage possible from costly IT implementations to enhance competitiveness, profitability, and survival in a rapidly changing environment. ICASE technology is a part of the infrastructure necessary to meet this challenge but appears to present significant difficulties in implementation. digital.library.unt.edu/ark:/67531/metadc278966/
Effects of Frustration Tolerance Training on Young Institutionalized Retarded Children
The major problem investigated was to ascertain the extent to which a training program designed specifically to increase frustration tolerance would reduce selected behavioral problems in institutionalized mentally retarded children. Of lesser importance was the problem of examining the extent to which the prescribed training program had differential effects on brain-injured and non-brain-injured retarded children. digital.library.unt.edu/ark:/67531/metadc278989/
Convergence of Self and Other Ratings of Personality: a Structural Equation Analysis
Recently, multi-source feedback has been a popular way of providing performance-related feedback to individuals in many organizations. Many who use multi-source feedback consider Rating Convergence, others seeing target individuals as they see themselves, to be a positive outcome of this process. However, the variables that account for Rating Convergence are not known. This study investigated whether the personality factor Extroversion and Behavioral Consistency, acting as a moderator variable, could account for Self-other Rating Convergence, particularly the Convergence between self and peer Ratings. The sample consisted of 235 mid-level managers from a variety of industries who were participants in individual career development workshops. Using structural equation modeling, the results indicated that a model consisting of a single Extroversion factor could account for the convergence of self-peer ratings. This finding calls into question the significance of Rating Convergence when using multi-source rating instruments that provide feedback on trait characteristics since it may be heavily influenced by a single personality factor rather than observers' comprehensive understanding of the ratee's performance. digital.library.unt.edu/ark:/67531/metadc278950/

Korean Students' Perceptions of the Effectiveness of their Internship Experiences in the Hospitality Industry in Korea
This research study assessed Korean students' perceptions and overall satisfaction levels regarding the effectiveness of their hospitality internship experiences. Relationships with demographic characteristics were identified. The sample was comprised of 74 senior-level university students enrolled in hospitality and/or tourism management programs who were completing an internship in Korea. Generally, students exhibited low agreement levels on the internship program aspects being investigated. Previous work experience was the most common factor influencing students' perceptions of their internship experiences. Agreement levels increased with length of prior work experience. Type of internship workplace, expectation of an employment offer, age and gender were found to influence students' perceptions of the internship experiences. digital.library.unt.edu/ark:/67531/metadc278968/

Mobile Order Theory as Applied to Polycyclic Aromatic Heterocycles
Experimental mole fraction solubilities of benzil, thianthrene, trans-stilbene, thioxanthen-9-one, diphenyl sulfone and dibenzothiophene sulfone are determined in pure noncomplexing and complexing solvents. Predicted solubility values are calculated for benzil, thianthrene, trans-stilbene and thioxanthen-9-one using expressions derived from Mobile Order theory. Large deviations between experimental and predicted solubilities in alcohol solvents exist, therefore optimized solute - solvent association constants are determined. Previously measured thianthrene solubilities in five binary alkane + cyclohexane solvent mixtures are compared with values predicted from Mobile Order theory using the measured solubility in each of the pure solvents as input parameters. The experimental mole fraction solubility of benzil in eight binary alcohol + 1-octanol solvent mixtures are also measured and compared with predicted values. digital.library.unt.edu/ark:/67531/metadc278994/
Distribution and Probable Sources of Nitrate in the Seymour Aquifer, North Central Texas, USA
Access: Use of this item is restricted to the UNT Community.
This study utilized GIS and statistical methods to map the spatial variability of nitrate and related groundwater constituents in 30 counties above the Seymour Aquifer, analyze temporal patterns of nitrate pollution, identify probable sources of pollution, and recommend water development strategies to minimize exposure to nitrate and reduce future aquifer contamination. Nitrate concentrations in excess of 44 mg/L (US EPA limit) were commonly observed in the Seymour Aquifer region, especially in the central agricultural belt. Data indicated that this is an ongoing problem in the Seymour Aquifer and that agricultural activity and rural septic systems are the likely sources of the nitrate. Inconclusive results emphasized the need for a more comprehensive spatial and temporal water quality monitoring. digital.library.unt.edu/ark:/67531/metadc2759/

"Stately Temples": Consubstantiality and Consciousness in Frances E. W. Harper's Iola Leroy; or Shadows Uplifted
The purpose of this master's thesis is to examine Frances Harper's narrative strategy and moral didacticism in Iola Leroy: or Shadows Uplifted (1892) as she strives to achieve consubstantiality and a "heightened consciousness" within her characters and her audience while adhering to the literary and feminist paradigms of the late nineteenth century. Harper identifies with her African-American male audience's dilemma of "double-consciousness" and their veil of androcentrism. She also identifies with her Euro-American female audience's delicate and matriarchal roles, while also attempting to uplift their position of the "Other" to the "One." Finally, with her African-American female audience, Harper identifies with their complex situatedness of "double-consciousness" and the "Other," while also attempting to uplift them from a historically imposed position of selflessness to one of empowerment. digital.library.unt.edu/ark:/67531/metadc278228/
Relationships among and Between Alcohol Consuption Rates, Alcohol Expectancies, and Early Recollections among Three Groups of College Males
Extensive documentation exists which firmly establishes the high use rates and disastrous consequences of alcohol consumption by university students. Use rates for this population have been linked to attitudes toward alcohol consumption, especially alcohol expectancies. Research to date on alcohol expectancies has shown differences in expectancies among various groups. However much of this research has been conducted without a theoretical basis, accomplishing little in explaining how beliefs and drinking behavior are related. The investigation was designed to explore the relationships among and between early recollections and alcohol expectancies and to explore how the contents of early recollections function in relation to expectancies in terms of alcohol consumption patterns among three groups of college males (student-athletes, fraternity men, and independents). The content of individuals' early recollections was analyzed and compared to expectancies and consumption rates for each of the three groups. The study addressed seven hypotheses regarding alcohol consumption rate comparisons, comparisons of consequences experienced as a result of alcohol consumption, comparisons of alcohol expectancies, and comparisons of reported content of early recollections. Multiple regression analysis was utilized to test the extent to which select early recollections and alcohol expectancy scores contributed to the explained variance in alcohol consumption patterns. digital.library.unt.edu/ark:/67531/metadc278278/

A Dialectical Approach to Studying Long-Distance Maintenance Strategies
Using both qualitative and quantitative methodology, this thesis investigates the tactics used by long-distance relational partners, the differences in use of the tactics between long-distance and proximal partners, the relationship among the maintenance tactics, and the relationship of the tactics to relational satisfaction. Seven relational maintenance strategies were identified from the investigation: affirmation, expression, high tech mediated communication, low tech mediated communication, future thought, negative disclosure, and together-time. Significant differences in the use of maintenance tactics between long-distance and proximal partners were discovered and several tactics were found to correlate with relational satisfaction for both relationship types. It is concluded that relational maintenance should be viewed from a multi-dimensional perspective that recognizes the impact relational dialectics have on relationships. digital.library.unt.edu/ark:/67531/metadc278229/

A Construct Validation Study of the Personality Inventory for Youth (PIY) Using an Incarcerated Juvenile Population
The Personality Inventory for Youth (PIY) is a recently developed, multiscale assessment instrument designed specifically for adolescents between the ages of nine and 18. The purpose of this archival study was to establish clinical correlates for the PIY scales. PIY profiles were collected from 100 juvenile files at the Gainesville State School and examined in conjunction with the Child Assessment Scale (CAS) and the Personal Attitude Scale (PAS) to provide evidence of convergent and discriminant validity. Results indicate modest to moderate convergent validity according to Campbell and Fiske's criteria for construct validity; however, discriminant results indicate considerable overlap among traits which are not expected to be highly correlated. digital.library.unt.edu/ark:/67531/metadc278298/

Intentions and Implementation of the Professional Development and Appraisal System in Texas
The purpose of this study was to describe the intentions of the designers of the Professional Development and Appraisal System (PDAS) in Texas and the perceptions of teachers regarding its implementation. Information for the study was gathered in two phases using two methodologies. The first was a semi-structured interview with four expert informants instrumental in the design and implementation of the PDAS at the state level. The second component of the study was conducted with teachers using a 37-item Likert survey. The population for this phase of the study was 150 elementary and 150 secondary teachers chosen randomly from three school districts in North Central Texas. The districts were selected to represent a variety of sizes in regard to student population and represent diverse student population characteristics and socioeconomic levels. Data from the semi-structured interviews and the returned surveys were analyzed to determine the designers' intentions and areas of emphasis and to describe the alignment the teachers' perceptions and the designers' intentions. Quantitative data gathered from the surveys were analyzed using descriptive statistics as well as a correlation and function analysis and analysis based on a Cronbach alpha coefficient. The analysis of data revealed the following: 1. Teachers perceived that the implementation of the PDAS has a high level of effect in the areas of learner-centered instruction; classroom management; support for all students; the professional growth of teachers; communication; learning application; and, TAAS improvement. 2. Teachers' perceptions were not affected by years of experience. 3. Teachers' perceptions were not affected by their field of instruction. One implication of this study is that the final design represents the intentions of designers, although the area of student achievement is not weighted as heavily in teachers' evaluations as was originally intended. Furthermore, education leaders in Texas may conclude that teachers perceive a high level of impact upon their classroom practices as a result of implementation of the PDAS instrument. If future research reveals that the perceived impact is accurate and that classroom practices of teachers did change as a result of the instrument's implementation to the degree perceived, then this is a model for policy implementation at the state level that is extremely effective. Furthermore, additional researchers may investigate the link between classroom practices and student achievement. This research study is a first step toward describing effective, replicable practices. digital.library.unt.edu/ark:/67531/metadc2721/

Women's and Men's Perceptions Regarding Perceived Speaker Sex and Politeness of Given Utterances
Women's and men's responses regarding perceived speaker sex and the politeness of given utterances were examined through the use of a questionnaire administered to 90 people, 45 men and 45 women. The questionnaire required respondents to rate the politeness of each utterance and label each as being more likely spoken by a man or by a woman. Factors possibly affecting perceptions--such as power, prestige, and the stereotypical conversational structures of both men and women--were addressed through others' research in this area. Additionally, all tested sentences were analyzed in light of linguistic politeness theory regarding on-record and off-record speech. This analysis details each utterance through examining the type of politeness strategy each utterance typifies. digital.library.unt.edu/ark:/67531/metadc277635/

Polish Spaces and Analytic Sets
A Polish space is a separable topological space that can be metrized by means of a complete metric. A subset A of a Polish space X is analytic if there is a Polish space Z and a continuous function f : Z —> X such that f(Z)= A. After proving that each uncountable Polish space contains a non-Borel analytic subset we conclude that there exists a universally measurable non-Borel set. digital.library.unt.edu/ark:/67531/metadc277605/
Circumfusion: a Composition for Real-Time Computer Music Spatialization System
Two of the leading methodologies for spatializing audio over multiple channels include non-real-time multi-track tape and variations of real-time systems that often involve complex configurations of hardware. Of the latter, composers relying on MIDI as a control source have used pairs of sound modules, effects units and automation capable mixers to achieve spatialization over four loudspeakers. These systems typically employ intensity panning, Doppler shifts and reverberation. The present research details the development of a compact spatialization system using a MAX patch controlling a Kurzweil K2500 sampler. This system supports real-time diffusion of up to six simultaneous sound files over eight loudspeakers while incorporating intensity panning, Doppler shifts, delays and filtering. The MAX patch allows composers to choose from several automatic sound spatialization trajectories or to use the mouse to draw and store their own trajectories for later playback. The piece, Circumfusion, is an eighteen-minute composition of electroacoustic music utilizing this spatialization system. digital.library.unt.edu/ark:/67531/metadc277632/
Entering the Circle: The Only Viable Hermeneutic for a Biblical Response to Ecocrisis
A paradox exists in attempting to resolve ecocrisis: awareness of ecological concerns is growing, but the crisis continues to escalate. John Firor, a well-known scientist, suggests that to resolve the paradox and hence ecocrisis, we need an alternative definition of "human beingness"--that is, a human ontology. digital.library.unt.edu/ark:/67531/metadc277659/

An Investigation of Psychopathy in a Female Jail Sample: a Study of Convergent and Discriminant Validity
The present study was designed to assess both the construct of psychopathy in a female jail sample as well as the quality of the measures that have been employed to assess this personality style. Utilizing the multitrait-multimethod matrix proposed by Campbell and Fiske (1959), the construct of psychopathy was measured via three instruments: (a) the Antisocial Scale of the Personality Assessment Inventory, (b) the Psychopathy Checklist - Revised, and (c) the Antisocial Scale of the Personality Disorder Examination. In addition, the predictive validity of each of these measures of psychopathy was evaluated to determine their ability to predict institutional violence and non-compliance. The results revealed significant convergence and divergence across the three instruments supporting the construct of psychopathy in a female jail sample. In addition, the measures of psychopathy demonstrated moderate predictive validity. digital.library.unt.edu/ark:/67531/metadc277640/
Hemispheric Interactions and Event-Related Potentials in Lateralized Stroop and Stroop Analog Tasks
Classical Stroop stimuli and newly developed face/word Stroop analog stimuli were used to investigate hemispheric interactions in Stroop interference effects (SEs) and corresponding event-related potentials (ERPs). Lateralized stimuli were presented unilaterally and bilaterally as congruent or incongruent color strip-word or face-word pairs (to invoke right hemisphere (RH) and left hemisphere (LH) specialization, respectively, in the latter case). The common finding for such tasks is that responses for the congruent condition are faster and more accurate than for the incongruent condition (i.e., the SE). A primary prediction is that the SE will be maximized when both the distractor and target components, or distractor alone, are presented to the specialized hemisphere (i.e., LH for words and RH for faces). A total of 88 right-handed University of North Texas students participated in one of four experiments. Participants manually responded to one component of the stimuli (i.e., color, face, or word), while ignoring the other. Behaviorally, participants showed a robust SE across all experiments, especially for the face/word task with word targets. Findings from the face/word Stroop analog tasks also indicated that SEs were produced by selective attention to either faces or words, implicating a role for top-down (controlled) processes. Hemispheric asymmetries were observed only for bilateral presentations of the face/word Stroop analog stimuli and did not differ for word versus face targets. The results suggest that the LH is less susceptible to interference from the RH than vice versa. Electrophysiologically, anterior N1 and P1, posterior P1 and N1, N2, and P3 components were identified. A SE was found for P3 amplitudes, but not latencies, across all four experiments such that the congruent condition generated greater amplitudes than the incongruent condition, suggesting that the P3 is an index of task difficulty. Surprisingly, SEs were also observed for the early ERP components, albeit embedded in higher order interactions. Taken together, the ERP evidence suggests that there is no single locus of the SE, and instead, the SE appears to be distributed over several stages of information processing. digital.library.unt.edu/ark:/67531/metadc277627/

Evaluation of MPLS Enabled Networks
Access: Use of this item is restricted to the UNT Community.
Recent developments in the Internet have inspired a wide range of business and consumer applications. The deployment of multimedia-based services has driven the demand for increased and guaranteed bandwidth requirements over the network. The diverse requirements of the wide range of users demand differentiated classes of service and quality assurance. The new technology of Multi-protocol label switching (MPLS) has emerged as a high performance and reliable option to address these challenges apart from the additional features that were not addressed before. This problem in lieu of thesis describes how the new paradigm of MPLS is advantageous over the conventional architecture. The motivation for this paradigm is discussed in the first part, followed by a detailed description of this new architecture. The information flow, the underlying protocols and the MPLS extensions to some of the traditional protocols are then discussed followed by the description of the simulation. The simulation results are used to show the advantages of the proposed technology. digital.library.unt.edu/ark:/67531/metadc5797/
Carbon nanotube/microwave interactions and applications to hydrogen fuel cells.
Access: Use of this item is restricted to the UNT Community.
One of the leading problems that will be carried into the 21st century is that of alternative fuels to get our planet away from the consumption of fossil fuels. There has been a growing interest in the use of nanotechnology to somehow aid in this progression. There are several unanswered questions in how to do this. It is known that carbon nanotubes will store hydrogen but it is unclear how to increase that storage capacity and how to remove this hydrogen fuel once stored. This document offers some answers to these questions. It is possible to implant more hydrogen in a nanotube sample using a technique of ion implantation at energy levels ~50keV and below. This, accompanied with the rapid removal of that stored hydrogen through the application of a microwave field, proves to be one promising avenue to solve these two unanswered questions. digital.library.unt.edu/ark:/67531/metadc5796/
An exploration of parental sensitivity and child cognitive and behavioral development.
The current study attempted to show the relationship of paternal sensitivity and maternal sensitivity and their possible influences on child cognitive and behavioral development. This study used data collected as part of the National Institute for Child Health and Human Development (NICHD) Study of Early Child Care, which is a longitudinal, multi-site study. Correlation and regression analyses were computed to examine relationships between the variables at child age 6 and 36 months. Results indicated paternal sensitivity was a significant positive predictor of child cognitive abilities and a negative predictor of both fathers' reports of children's externalizing and internalizing behaviors. Maternal sensitivity was a significant negative predictor of mothers' reports of children's externalizing behaviors. Interpretations of these results and directions for future research are discussed. digital.library.unt.edu/ark:/67531/metadc5794/
Populism and the Poll Tax: the Politics and Propaganda of Suffrage Restriction in North Texas, 1892-1904
This thesis challenges the traditional interpretation of the history of Populism in America through the use of an intensive regional study. Using precinct-level returns, this thesis proves that, contrary to the conclusions of more general studies, voters from predominately Populist areas in North Texas did not support the poll tax amendment that passed in November 1902. The Populists within this region demonstrated their frustration and distrust of the political process by leaving the polls in higher percentages than other voters between 1896 and 1902. The Populists that did participate in 1902 reentered the Democratic Party but did not support the poll tax, which was a major plank within the Democratic platform. This thesis also proves that the poll tax had a significant effect in reducing the electorate in North Texas. digital.library.unt.edu/ark:/67531/metadc278757/
Dark Houses: Navigating Space and Negotiating Silence in the Novels of Faulkner, Warren and Morrison
Poe's "The Fall of the House of Usher," as early as 1839, reveals an uneasiness about the space of the house. Most literary scholars accept that this anxiety exists and causes some tension, since it seems antithetical to another dominant motif, that of the power of place and the home as sanctuary. My critical persona, like Poe's narrator in "The House of Usher," looks into a dark, silent tarn and shudders to see in it not only the reflection of the House of Usher, but perhaps the whole of what is "Southern" in Southern Literature. Many characters who inhabit the worlds of Southern stories also inhabit houses that, like the House of Usher, are built on the faulty foundation of an ideological system that divides the world into inside(r)/outside(r) and along numerous other binary lines. The task of constructing the self in spaces that house such ideologies poses a challenge to the characters in the works under consideration in this study, and their success in doing so is dependant on their ability to speak authentically in the language of silence and to dwell instead of to just inhabit interior spaces. In my reading of Faulkner and Warren, this ideology of division is clearly to be at fault in the collapse of houses, just as it is seen to be in the House of Usher. This emphasis is especially conspicuous in several works, beginning with Faulkner's Absalom, Absalom! and its (pre)text, "Evangeline." Warren carries the motif forward in his late novels, Flood and Meet Me in the Green Glen. I examine these works relative to spatial analysis and an aesthetic of absence, including an interpretation of silence as a mode of authentic saying. I then discuss these motifs as they are operating in Toni Morrison's Beloved, and finally take Song of Solomon as both an end and a beginning to these texts' concerns with collapsing structures of narrative and house. digital.library.unt.edu/ark:/67531/metadc2732/
Is There Justice in Mercy? the Retributive Philosophies of Executive Clemency
Executive clemency is assumed to be a mechanism to correct miscarriages of justice brought about by the criminal justice system, yet little empirical research exists to confirm this assumption. This research study examined the types of rationales cited in 799 cases of executive clemency from six states from 2005 to 2012. Rationales based upon retributive philosophies, in which a miscarriage of justice was cited, were further analyzed. This analysis revealed that only seven percent of all clemency decisions from the examined states cited retributive rationales. Of the fifty-six grants of clemency that cited retributive rationales, most were granted in the forms of pardons. The analysis indicated that executive clemency is utilized as a mechanism to correct injustices, specifically in cases of innocence. This study concludes with a discussion of policy implications and the reliance on executive clemency as a fail-safe to the criminal justice system. digital.library.unt.edu/ark:/67531/metadc271818/
Novice Teachers' Stories Represented As a Graphic Narrative
The issue of alternative certification teacher training has greatly affected art education over three decades. As a result of training through alternative certification, many art educators enter the profession unprepared and unable to cope with the realities of teaching. This study attempts to understand and represent the experiences and struggles of four alternatively certified art teachers, including myself. By reading these stories, others within the education community can empathize with and provide support for struggling novice teachers. This creative thesis uses a graphic novel format to represent participants' stories. By combining text and imagery, the graphic novel format provides different meanings, interpretations, and insights into the teachers' lives. This medium offered a unique and rich perspective on the stories of what it is like being an alternatively certified art teacher. digital.library.unt.edu/ark:/67531/metadc271802/
Data Transmission in Quantized Consensus
In the world of networked system, average consensus is an important dimension of co-ordinate control and cooperation. Since the communication medium is digital, real value cannot be transmitted and we need to perform quantization before data transmission. But for the quantization, error is introduced in exact value and initial average is lost. Based on this limitation, my 16 bit quantization method (sending MSB in 1-4 cycle and MSB+LSB in 5th cycle) reduces error significantly and preserves initial average. Besides, it works on all types of graphs (star, complete, ring, random geometric graph). My other algorithm, distributing averaging algorithm (PQDA) with probabilistic quantization also works on random geometric graph, star, ring and slow co-herency graph. It shows significant reduced error and attain strict consensus. digital.library.unt.edu/ark:/67531/metadc271874/
Leader Developmental Readiness of Generation Y in the Training Industry
Members of Generation Y in the training and development industry will be required to assume leadership roles as Baby Boomers retire, yet little empirical research exists regarding how best to prepare them for leadership. The purpose of this study was to examine differences in leader developmental readiness between generational cohorts in the training industry, specifically Baby Boomers, Generation X, and Generation Y. Leader developmental readiness provided a definition of developmental readiness for leaders using the five constructs (learning goal orientation, developmental efficacy, self-awareness, leader complexity, and metacognitive ability). A volunteer sample was compiled from members of the ASTD National LinkedIN group (n = 636). Results were analyzed using structured means analysis with maximum likelihood (ML) estimation. Generational cohorts demonstrated differences in leader developmental readiness. Baby Boomers indicated statistically and practically higher metacognitive ability and developmental efficacy than Generation Y. Results demonstrated statistically and practically higher leader complexity in Generation Y and both Generation X and Baby Boomers. These results should inform leader development practitioners as they continue to use existing methods in preparing the different generations for leader development interventions while pointing to possible needs to increase the metacognitive ability and developmental efficacy in Generation Y and ensure accurate perception of leader complexity in those individuals. Further research would be helpful to confirm or refute findings and expand on the target population for enhanced generalizability. digital.library.unt.edu/ark:/67531/metadc271816/
