An integrative investigation of person-vocation fit, person-organization fit, and person-job fit perceptions.

Description: Person-environment (PE) fit has been considered one of the most pervasive concepts in psychology. This study presents an integrative investigation of three levels of PE fit: person-vocation (PV) fit, person-organization (PO) fit, and person-job (PJ) fit, using multiple conceptualizations (e.g., value congruence, needs-supplies fit) of each fit level. While a trend in the PE fit literature has been the inclusion of only one fit level with a single conceptualization, researchers call for the addition of multiple conceptualizations of multiple fit levels in a single study. Traditionally, PO fit has been conceptualized as value congruence, whereas PV fit has remained untouched in the literature investigating the direct measurement of fit perceptions. Therefore, new fit perceptions scales assessing PO fit using a needs-supplies fit conceptualization and PV fit using a variety of conceptualizations were introduced. To address the limitation of employing direct measures, common method variance was modeled with a positive affect factor. The study accomplished two objectives. First, a previously supported three-factor model of fit perceptions consisting of PO value congruence (PO-VC), PJ needs-supplies (PJ-NS), and PJ demands-abilities (PJ-DA) fit was strongly replicated. Second, this model was expanded by examining additional conceptualizations (needs-supplies, demands-abilities fit, value, personality, and interest congruence) of fit levels (PV, PO, and PJ fit). Results suggested that professionals make distinctions based on both the fit level and fit conceptualization and these fit perceptions uniquely influence their attitudes and behaviors. A six-factor model (PO-VC, PJ-NS, PJ-DA, PO needs-supplies fit [PO-NS], PV demands-abilities fit [PV-DA], and general PV fit) best fit the data. Providing ample evidence of construct validity, PO fit perceptions (PO-VC and PO-NS fit) were related to the organization-focused outcome of organizational identification, whereas the profession-focused outcome of occupational commitment was exclusively predicted by PV fit perceptions (PV-DA and general PV fit). As expected, both needs-supplies fit ...

Interfacial Study of Copper Electrodeposition with the Electrochemical Quartz Crystal Microbalance (EQCM)

Description: The electrochemical quartz crystal microbalance (EQCM) has been proven an effective mean of monitoring up to nano-scale mass changes related to electrode potential variations at its surface. The principles of operation are based on the converse piezoelectric response of quartz crystals to mass variations on the crystal surface. In this work, principles and operations of the EQCM and piezo-electrodes are discussed. A conductive oxide, ruthenium oxide (RuO2) is a promising material to be used as a diffusion barrier for metal interconnects. Characterization of copper underpotential deposition (UPD) on ruthenium and RuO2 electrodes by means of electrochemical methods and other spectroscopic methods is presented. Copper electrodeposition in platinum and ruthenium substrates is investigated at pH values higher than zero. In pH=5 solutions, the rise in local pH caused by the reduction of oxygen leads to the formation of a precipitate, characterized as posnjakite or basic copper sulfate by means of X-ray electron spectroscopy and X-ray diffraction. The mechanism of formation is studied by means of the EQCM, presenting this technique as a powerful in-situ sensing device.

Knowledge management in virtual organizations: A study of a best practices knowledge transfer model.

Description: Knowledge management is a major concern for organizations today, and in spite of investments in technology, knowledge transfer remains problematic. This study sought to determine whether a relationship exists among participant group demographics (experience), implementation of an integrated knowledge transfer system (best practices model), knowledge transfer barriers, and knowledge transfer project (Web-based training) outcome in a virtual organization. The participant organization was a network of individuals and groups who practice patient advocacy in the research and treatment of cancer. These advocates volunteer in various capacities and are not collocated nor do they report to any single organizational entity. Volunteer participants were randomly assigned to a treatment or control condition. The treatment participants received a training supplement based upon a best practices knowledge transfer model. All participants reviewed a Web-based communications training module scheduled for deployment by the participant organization. Upon completion of the training program, participants were instructed to practice specific techniques from the program. At the end of this period, participants completed an online survey that measured demographics, perceived barriers to the knowledge transfer, and project outcome. Knowledge transfer barriers were defined as knowledge, source, recipient, and organizational context characteristics that inhibit the expected transfer. Project outcome was a composite score of items measuring completion time, budget, and satisfaction of the user. Multiple regression identified two significant predictor variables, source (the training program and implementation) and experience (amount of time spent in advocacy practice). Additional analyses found knowledge (causal ambiguity and unproven knowledge) and the experimental treatment condition to show a strong relationship with the explained variance of the dependent variable, knowledge transfer project outcome. Results suggest that an online training implementation is a valid tool for certain specific transfer design characteristics. Experience was a negative predictor of outcome, suggesting that participant-specific level of training material may produce improved ...

Leadership preferences of a Generation Y cohort: A mixed methods study.

Description: Presently there are four generational cohorts in the workplace. Born from 1977 to 1997, the youngest cohort group, referred to as Generation Y (or Gen Y) in this study, has 81 million members, of whom over 29 million are already in the workplace. The importance of leader-subordinate relationships in the workplace has been confirmed; in recognizing this, leaders must identify and adapt to the changing era-shaped needs of employees, who cannot fully participate in organizational life if their most urgent needs are not being met. Because Gen Y employees are only now entering the workforce, little is actually known about the workplace needs of this cohort group. This study attempted to determine leadership needs of a Gen Y cohort as a means to enhance workplace relationships in the 21st century organization. A sequential, mixed methods study was employed to explore leadership preferences of a Gen Y cohort. Initially, focus group interviews were used to generate leadership themes. Based on these themes, an instrument was designed, and Gen Y business students from three higher education institutions were surveyed. Confirmatory factor analysis using LISREL software was used to test the themes. The driving force behind this research design was to build a foundation of understanding through inductive research (qualitative) and to test and enrich the foundation through deductive means (quantitative).

Lone Star under the Rising Sun: Texas's "Lost Battalion," 2nd Battalion, 131st Field Artillery Regiment, During World War II

Description: In March 1942, the 2nd Battalion, 131st Field Artillery Regiment, 36th Division, surrendered to the Japanese Imperial Army on Java in the Dutch East Indies. Shortly after the surrender, the men of the 2nd Battalion were joined as prisoners-of-war by the sailors and Marines who survived the sinking of the heavy cruiser USS Houston. From March 1942 until the end of World War II, these men lived in various Japanese prison camps throughout the Dutch East Indies, Southeast Asia, and in the Japanese home islands. Forced to labor for their captors for the duration of the conflict, they performed extremely difficult tasks, including working in industrial plants and mining coal in Japan, and most notably, constructing the infamous Burma-Thailand Death Railway. During their three-and-one-half years of captivity, these prisoners experienced brutality at the hands of the Japanese. Enduring prolonged malnutrition and extreme overwork, they suffered from numerous tropical and dietary diseases while receiving almost no medical care. Each day, these men lived in fear of being beaten and tortured, and for months at a time they witnessed the agonizing deaths of their friends and countrymen. In spite of the conditions they faced, most survived to return to the United States at war's end. This study examines the experiences of these former prisoners from 1940 to 1945 and attempts to explain how they survived.

A magnetorheological study of single-walled and multi-walled carbon nanotube dispersions in mineral oil and epoxy resin.

Description: Single wall carbon nanotubes (SWNTs) and multi-walled carbon nanotubes (MWNTs) were dispersed in mineral oil and epoxy resin. The magnetorheological properties of these dispersions were studied using a parallel plate rheometer. Strain sweeps, frequency sweeps, magneto sweeps and steady shear tests were conducted in various magnetic fields. G', G", h* and ty increased with increasing magnetic field, which was partially attributed to the increasing degree of the alignment of nanotubes in a stronger magnetic field. The SWNT/mo dispersions exhibited more pronounced magnetic field dependence than SWNT/ep and MWNT/mo counterparts due to their much lower viscosity. The alignment of SWNTs in mineral oil increased with rising nanotube concentration up to 2.5vol% but were significantly restricted at 6.41vol% due to nanotube flocculation.

Mainstream Success Following Placement in a Modified Type II Setting

Description: The topic of alternative schools is widely available in the literature; however, once a student has been labeled a "troublemaker" and has been placed in a District Alternative Education Program (DAEP), a Type II setting, there is limited information about the overall success of students upon their return to the mainstream. This study compared the success of students formerly placed in a modified disciplinary Type II setting, once they have returned to the mainstream, with their success prior to disciplinary placement. The purpose of the study was to examine if disciplinary measures that remove students from the mainstream environment negatively impact the variables that measure school success, despite legislative mandates such as No Child Left Behind, which advocates success for every student. The population for this study was 86 7th- through 11th-grade students assigned to a DAEP in Texas during the spring of 2003. A comparison of pre- and post-placement dependent variables measuring school success-attendance, passing core courses, behavioral achievement, standardized test score achievement, recidivism, and dropout rates-comprised this study. The independent variables-gender, ethnicity, grade level, socioeconomic status, and disciplinary offense-were used to compare and analyze each dependent variable. The dependent variables of attendance, passing core courses, and behavior demonstrated a decline in the measurement of school success across time. The only dependent variable that demonstrated improvement between the pre- and post-placement periods was achievement on standardized test scores. From the number of students who withdrew from the mainstream during the post-placement semesters, large recidivism and dropout rates were determined, which reflected the large percentage of students who were not successful in the district's mainstream. The comparisons of dependent variables by independent variables resulted in significance only in the analyses of attendance by grade level. This interaction was determined to be significant since p < .05. During both post-placement semesters, ...

Meta-Parenting in Parents of Infants and Toddlers

Description: Meta-parenting, defined as parents thinking about their parenting, has been identified and is a new field of research. The purposes of this study were to add to the existing knowledge of meta-parenting and to compare the influences of gender, work status, and parenting experience on meta-parenting occurring in parents of infants and toddlers. Sixty parents participated either electronically or by completing a written survey and reported engaging from "sometimes" to "usually" in four domains of meta-parenting: anticipating, assessing, reflecting, and problem-solving. Gender, work status, and parenting experience did not significantly influence participants' meta-parenting scores. Parents were found to have a higher sense of satisfaction and overall sense of competence when they engaged in higher levels of meta-parenting.

Miguel Yuste: His Works for Clarinet and His Influence on the Spanish Clarinet School of Playing in the Twentieth Century, A Lecture Recital, Together with Three Recitals of Selected Works by Bax, Mason, Khachaturian, Chausson, Bozza, Beethoven, and Others

Description: The popularity of the clarinet in Spain is second only to that of the guitar, and there is a rich tradition of clarinet playing that is accompanied by an equally rich repertoire of music for the clarinet by Spanish composers. The works for clarinet and piano by Miguel Yuste (1870-1947) are among this little known repertoire. In the early twentieth century it was thought that Miguel Yuste wrote over one hundred works for clarinet. However, current research suggests that this is incorrect. What is known is that seven works for clarinet and piano have been published. Miguel Yuste and his music are pivotal in the establishment of the strong clarinet tradition for which Spain is presently known. In his thirty years as the clarinet professor at the Real Conservatorio Superior de Música de Madrid (1910-1940), Miguel Yuste's music and pedagogical ideas became, and continue to be among the foundations of Spanish clarinet playing. This project discusses each published work and presents current research on the works composed for clarinet and piano by Miguel Yuste. After a brief history of Spain's music and social climate in which it developed (Ch. 2), this document discusses the introduction of the clarinet in Spain, clarinet pedagogy at the Madrid Conservatory (Ch. 2), and Miguel Yuste's influence within that pedagogy (Ch. 3). Establishing contact with living clarinetists whose music education was directly influenced by Miguel Yuste and/or his students provides invaluable insight into the traditional performance practice of the works and the extent to which Miguel Yuste influenced Spanish clarinetists in the twentieth century. Chapter four presents an annotated bibliography and brief discussion of the extant works for clarinet by Miguel Yuste. Each annotation includes the title of the work, publisher, date of publication, duration, and any commercially available recordings.

Molecular and biochemical characterization of phospholipase D in cotton (Gossypium hirsutum L) seedlings.

Description: N-Acylethanolamines (NAEs) are enriched in seed-derived tissues and are believed to be formed from the membrane phospholipid, N-acylphosphatidylethanolamine (NAPE) via the action of phospholipase D (PLD). In an effort to identify a functional NAPE-PLD in cotton seeds and seedlings, we have screened a cotton seedling cDNA (cotyledon mRNA from 48 h dark grown seedlings) library with a 1.2 kb tobacco partial cDNA fragment encoding the middle third of a putative PLDβ/γ (genbank accession, AF195614) isoform. Six plaques were isolated from the Uni-ZAP lambda library, excised as pBluescript SK(-) phagemids and subjected to nucleotide sequence analysis. Alignment of derived sequences with Arabidopsis PLD family members indicated that the cDNAs represent six different PLD gene products -three putative PLD β isoforms and three putative PLD δ isoforms. The PLD β isoforms, designated Ghpldβ1a, GHpldβ1b and a truncated Ghpldβ1b isoform. Both the full-length PLD β proteins contained characteristic HKxxxxD catalytic domains, a PC-binding domain, a PIP2-binding domain and a C2 domain. In addition both cotton PLD β isoforms had a N-terminal "SPQY" rich domain which appeared to be unique to these PLDs. The three PLD δ isoforms, designated Ghpldδ1a, Ghpldδ1b and Ghpldδ1b-2 encode full-length PLDδ proteins, and like the above PLDs, contained the characteristic catalytic and regulatory domains. The expression of Ghpldδ1b showed hydrolytic and transphosphatidylation activity toward radiolabelled phosphatidylcholine (PC) but it appears Ghpldδ1b does not utilize NAPE as a substrate to produce NAEs nor does it seem to be suppressed by NAEs.

Nodal Resistance Measurement System

Description: The latest development in the measurement techniques has resulted in fast improvements in the instruments used for measurement of various electrical quantities. A common problem in such instruments is the automation of acquiring, retrieving and controlling the measurements by a computer or a laptop. In this study, nodal resistance measurement (NRM) system is developed to solve the above problem. The purpose of this study is to design and develop a compact electronic board, which measures electrical resistance, and a computer or a laptop controls the board. For the above purpose, surface nodal points are created on the surface of the sample electrically conductive material. The nodal points are connected to the compact electronic board and this board is connected to the computer. The user selects the nodal points, from the computer, between which the NRM system measures the electrical resistance and displays the measured quantity on the computer.

Parental decision-making regarding their child's participation in a middle-school talent search.

Description: The present study sought to identify variables that predicted parental decision-making regarding their child's participation in a national gifted and talented identification program for middle school students and subsequent participation in recommended educational options. One hundred sixty-nine parents of students who qualified for either the 2001-2002 or 2002-2003 Duke Talent Identification Program participated in the study. The students were drawn from two large public school districts and six small private schools in a large metropolitan area in the southwestern United States. Both quantitative and qualitative methods were used to identify the variables predictive of parental decision-making regarding talent search participation. Each parent completed a questionnaire consisting of both multiple-choice and open-ended questions. Selected parents participated in structured follow-up interviews. The results of the study indicated that parental perception of the helpfulness of school personnel in explaining the purpose and process of the talent search was most predictive of participation in the talent search. The educational level of the father, parent's prior awareness of the purpose and process of talent search, and the number of enrichment activities in which the child had previously participated were also predictive of talent search participation. Qualitative data indicated that parents of both participants and nonparticipants had a limited understanding of the purpose, diagnostic power, and potential benefits of the talent search. Very few parents chose to seek extracurricular or curricular/instructional options following the talent search testing. Qualitative data indicated that parents did not choose these options due to cost, logistical concerns regarding the special programs, and reservations about the developmental appropriateness of such options for middle school students. Although talent searches are sponsored and administered by organizations outside the local school, this study suggests that parents mostly rely on their local school for notification of their child's nomination, information on the purpose and benefits of ...

Perceived features and similarity of images: An investigation into their relationships and a test of Tversky's contrast model.

Description: The creation, storage, manipulation, and transmission of images have become less costly and more efficient. Consequently, the numbers of images and their users are growing rapidly. This poses challenges to those who organize and provide access to them. One of these challenges is similarity matching. Most current content-based image retrieval (CBIR) systems which can extract only low-level visual features such as color, shape, and texture, use similarity measures based on geometric models of similarity. However, most human similarity judgment data violate the metric axioms of these models. Tversky's (1977) contrast model, which defines similarity as a feature contrast task and equates the degree of similarity of two stimuli to a linear combination of their common and distinctive features, explains human similarity judgments much better than the geometric models. This study tested the contrast model as a conceptual framework to investigate the nature of the relationships between features and similarity of images as perceived by human judges. Data were collected from 150 participants who performed two tasks: an image description and a similarity judgment task. Qualitative methods (content analysis) and quantitative (correlational) methods were used to seek answers to four research questions related to the relationships between common and distinctive features and similarity judgments of images as well as measures of their common and distinctive features. Structural equation modeling, correlation analysis, and regression analysis confirmed the relationships between perceived features and similarity of objects hypothesized by Tversky (1977). Tversky's (1977) contrast model based upon a combination of two methods for measuring common and distinctive features, and two methods for measuring similarity produced statistically significant structural coefficients between the independent latent variables (common and distinctive features) and the dependent latent variable (similarity). This model fit the data well for a sample of 30 (435 pairs of) images and 150 participants (&#967;2 =16.97, ...

Philosophical Implications on Trombone Performance and Pedagogy in Andre Lafosse's Curriculum at the Paris Conservatory

Description: During his tenure as the professor of trombone at the Paris Conservatory, Andre Lafosse wrote the Traite de Pedagogie du Trombone a Coulisse addressing trombone pedagogy that was to be studied in conjunction with his method and etude books, Methode Complete de Trombone and Vade Mecum du Tromboniste. The pedagogic philosophy reflects Lafosse's own experiences as an orchestral musician in France in the early 20th century. Lafosse designed and used his treatise to prepare students to be effective teachers after their graduation from the Conservatory. The scope of preparation for Lafosse's trombone class, however, was limited. He did not attempt to provide a text or tutor that would prepare trombonists for any career in music: Lafosse was primarily concerned with orchestral trombone playing, as reflected in musical exercises, instrument designation, and repertoire references. Solo performance skills are also explained at length in his treatise, and Lafosse includes his own solo transcriptions in the curriculum. This emphasis placed on performing as a soloist appears to oppose Lafosse's implied preference for orchestral performance. Throughout his career as a trombone professor Andre Lafosse compiled and wrote music that emphasized elements of trombone technique based on the French solo and orchestral repertoire. His primary concern as a teacher was developing the skills for an orchestral career in France, but his method was to use exercises that focused on certain technical aspects of trombone performance. The exercises and etudes chosen were all influenced by French music regarding the skills deemed important by Lafosse (i.e. those required by the French orchestral and solo repertoire) and the acoustic design of the trombone in France in the early 20th century. Considering the holistic context of Lafosse'ss role at the Paris Conservatory, Lafosse's curriculum and methodology should be deemed appropriately designed for the best interest of the students.

Piano Concerto No. 4 in D Minor, Op. 70 by Anton Rubinstein: An analytical and historical study.

Description: Anton Rubinstein was primarily recognized as one of the greatest pianists of his time. However, Rubinstein yearned for recognition as a composer and worked prodigiously to realize that goal. Unfortunately, Rubinstein's works were virtually unknown today. One of Rubinstein's finest compositions, the Piano Concerto in D Minor, op. 70 has been the most frequently performed. It is one of the first "Russian" concertos that was written by a Russian composer, and was performed in Russian concert halls instead of the homes of Russian aristocracy. It is also considered the most successful and harmonious convergent of various musical styles which influenced Rubinstein. However, there is no formal, detailed analysis of the Concerto in the entire music literature. Therefore, the main purpose of this dissertation is to provide a thorough study of the Concerto from an analytical and historical standpoint. Rubinstein was also one of the most eminent educators in Russia. The St. Petersburg Conservatory of Music, which Rubinstein helped found in 1862, has to this day produced some of the most influential musicians in Russia. The other purpose of this dissertation is to evaluate Rubinstein's role as music educator. An overview of Rubinstein's works for piano and orchestra offers a general idea of his compositional style. Literature on Anton Rubinstein currently available is limited. The two most valuable primary sources are Rubinstein's Autobiography of Anton Rubinstein, and Rubinstein's A Conversation on Music. Jeremy Norris's The Russian Piano Concerto, Volume I: The Nineteenth Century provides an insightful but short analysis on the Concerto. Sources discussing Anton Rubinstein as a pianist and an educator are relatively plentiful. Larry Sitsky's Anton Rubinstein: Annotated Catalog of Piano Works and Biography is an excellent work on Rubinstein's piano works. This dissertation includes four chapters: Chapter 1 - Introduction Chapter 2 - Rubinstein's works for piano and ...

Poetry and Patronage: Alessandro Scarlatti, The Accademia Degli Arcadia, and the Development of the Conversazione Cantata in Rome 1700-1710

Description: The special relationship of patrons, librettists, and composers, in the Accademia degli'Arcadia in Rome from 1700-1710 appears in Alessandro Scarlatti's settings of Antonio Ottoboni's cantata librettos in the anthology GB Lbm. Add. 34056. An examination of Arcadian cantatas and their texts reveals the nature of their audience, function, and their place within the historical development of the genre. The conversazione cantata did not exist outside of Rome and was popular for only a brief period in the early eighteenth century. Critical examination of primary sources, including minutes from the Arcadian Academy meetings as well as household documents regarding the Cardinals Ottoboni and Pamphili, Prince Ruspoli, and other noble families, sheds light on the culture of the Arcadian Academy and the cantata within it, broader study clarifies the individuality of the conversazione cantata within Rome, and closer study of the contribution of the greatest cantata composer 1700-1710, Alessandro Scarlatti.

Present tense marking as a synopsis of Southern American English: Plural verbal -s and zero 3rd singular.

Description: This thesis explores the evolution plural verbal -s ("People thinks he is guilty") and zero 3rd singular ("He think he is guilty") in data from two sources on Southern English: The Linguistic Atlas of the Gulf States (LAGS) and The Linguistic Atlas of the Middle and South Atlantic States (LAMSAS). The research questions that underlie this study consider (1) the demographic association of plural verbal -s and zero 3rd singular, (2) the maintenance of each form, (3) the constraints on their use, and (4) the origins of -s variability. The atlas data suggest the following for plural verbal -s: (1) it has a British source, (2) it was present in both African American Vernacular English (AAVE) and early Southern White English (SWE), and (3) there were different grammatical constraints on its use in AAVE and SWE. Data for zero 3rd singular -s suggest this form (1) did not have a British source and (2) that it has historically been an AAVE feature.

Primary revenue streams of Hispanic-serving community colleges in Texas.

Description: This study examined the extent and sources of primary revenue for Hispanic-, African-American-, and Caucasian-serving public community colleges in Texas. The study also examined differences between and among primary revenue streams for these institutions. The public community colleges were identified as Hispanic-, African-American-, and Caucasian-serving based upon the percentage of enrollments for each ethnic classification. A comparative model was developed for the primary revenue streams of in-district student tuition, out-of-district student tuition differentials, out-of-state student tuition differentials, ad valorem property tax revenue per in-district contact hour, and state appropriations. Statistical Packages for the Social Sciences (SPSS) was utilized to conduct multiple-factor analysis of variance (ANOVA) on the data set to examine differences between and among the several variables. Post hoc tests were performed where necessary. Difference was identified in in-district student tuition. Post hoc analysis demonstrated that difference existed between Hispanic-serving and African-American-serving community colleges. No difference was identified in the remaining primary revenue streams.

Privacy Concerns and Personality Traits Influencing Online Behavior: A Structural Model

Description: The concept of privacy has proven difficult to analyze because of its subjective nature and susceptibility to psychological and contextual influences. This study challenges the concept of privacy as a valid construct for addressing individuals' concerns regarding online disclosure of personal information, based on the premise that underlying behavioral traits offer a more reliable and temporally stable measure of privacy-oriented behavior than do snapshots of environmentally induced emotional states typically measured by opinion polls. This study investigated the relationship of personality characteristics associated with individuals' general privacy-related behavior to their online privacy behaviors and concerns. Two latent constructs, Functional Privacy Orientation and Online Privacy Orientation, were formulated. Functional Privacy Orientation is defined as a general measure of individuals' perception of control over their privacy. It was measured using the factors General Disclosiveness, Locus of Control, Generalized Trust, Risk Orientation, and Risk Propensity as indicator variables. Online Privacy Orientation is defined as a measure of individuals' perception of control over their privacy in an online environment. It was measured using the factors Willingness to Disclose Online, Level of Privacy Concern, Information Management Privacy Concerns, and Reported Online Disclosure as indicator variables. A survey questionnaire that included two new instruments to measure online disclosure and a willingness to disclose online was used to collect data from a sample of 274 adults. Indicator variables for each of the latent constructs, Functional Privacy Orientation and Online Privacy Orientation, were evaluated using corrected item-total correlations, factor analysis, and coefficient alpha. The measurement models and relationship between Functional Privacy Orientation and Online Privacy Orientation were assessed using exploratory factor analysis and structural equation modeling respectively. The structural model supported the hypothesis that Functional Privacy Orientation significantly influences Online Privacy Orientation. Theoretical, methodological, and practical implications and suggestions for analysis of privacy concerns and behavior are presented.

Procedural content creation and technologies for 3D graphics applications and games.

Description: The recent transformation of consumer graphics (CG) cards into powerful 3D rendering processors is due in large measure to the success of game developers in delivering mass market entertainment software that feature highly immersive and captivating virtual environments. Despite this success, 3D CG application development is becoming increasingly handicapped by the inability of traditional content creation methods to keep up with the demand for content. The term content is used here to refer to any data operated on by application code that is meant for viewing, including 3D models, textures, animation sequences and maps or other data-intensive descriptions of virtual environments. Traditionally, content has been handcrafted by humans. A serious problem facing the interactive graphics software development community is how to increase the rate at which content can be produced to keep up with the increasingly rapid pace at which software for interactive applications can now be developed. Research addressing this problem centers around procedural content creation systems. By moving away from purely human content creation toward systems in which humans play a substantially less time-intensive but no less creative part in the process, procedural content creation opens new doors. From a qualitative standpoint, these types of systems will not rely less on human intervention but rather more since they will depend heavily on direction from a human in order to synthesize the desired content. This research draws heavily from the entertainment software domain but the research is broadly relevant to 3D graphics applications in general.

A Qualitative Research Study of How Extended Field Experience Prepares Special Education Teachers of Students with Emotional and Behavioral Disorders

Description: A well-prepared and qualified special education teacher is crucial to the performance of students with emotional and behavioral disorders (EBD). The prominent educators and federal government encourage the use of extended field experiences in preparing qualified special education teachers. The study examined the strengths and weaknesses of extended field experience in terms of the perceptions of the prospective teachers and teachers of students with EBD. Both individual interviews and a focus group were used to collect data. The results revealed that extended field experience benefits prospective teachers in showing the reality of the teachers' world, self-motivation assessment, and professional development. However, there were some improvements that could be made, including more placement selections and more practical knowledge.

Quality Management in Museum Information Systems: A Case Study of ISO 9001-2000 as an Evaluative Technique

Description: Museums are service-oriented information systems that provide access to information bearing materials contained in the museum's collections. Within museum environments, the primary vehicle for quality assurance and public accountability is the accreditation process of the American Association of Museums (AAM). Norbert Wiener founded the field of cybernetics, employing concepts of information feedback as a mechanism for system modification and control. W. Edwards Deming applied Wiener's principles to management theory, initiating the wave of change in manufacturing industries from production-driven to quality-driven systems. Today, the principles are embodied in the ISO 9000 International Standards for quality management systems (QMS), a globally-recognized set of standards, widely employed as a vehicle of quality management in manufacturing and service industries. The International Organization for Standardization defined a process for QMS registration against ISO 9001 that is similar in purpose to accreditation. This study's goals were to determine the degree of correspondence between elements of ISO 9001 and quality-related activities within museum environments, and to ascertain the relevance of ISO 9001-2000 as a technique of museum evaluation, parallel to accreditation. A content analysis compared museum activities to requirements specified in the ISO 9001-2000 International Standard. The study examined museum environment surrogates which consisted of (a) web sites of nine museum studies programs in the United States and (b) web sites of two museum professional associations, the AAM and the International Council of Museums (ICOM). Data items consisted of terms and phrases from the web sites and the associated context of each item. Affinity grouping of the data produced high degrees of correspondence to the categories and functional subcategories of ISO 9001. Many quality-related activities were found at the operational levels of museum environments, although not integrated as a QMS. If activities were unified as a QMS, the ISO 9001 Standard has potential for application as ...

Description: Though counselor education has always acknowledged the importance of work in the lives of individuals, there is a dearth of information concerning the worklives of counselor education faculty. The purpose of this study was to explore work and life variables that impact the work experiences of faculty members in counselor education. This study examined demographic or life variables including gender, age, ethnicity, sexual orientation, relationship status, and parenting status; and work-related variables including rank, sexual harassment, gender discrimination, salary equity, mentoring, teaching activities, service activities, publication for collaboration, and decision-making representation. Three hundred and twenty-eight counselor education faculty members across the United States participated in the study. Participants completed a mailed questionnaire including demographic information, quantitative survey questions, and related qualitative items designed to investigate work and life factors impacting the subjective work experiences of counselor educators. Chi-square analyses and analysis of qualitative responses related to four research hypotheses indicated that experience of the work environment for counselor educators is impacted by gender, tenure rank, age, and relationship status. Post-hoc analysis indicated that work experiences are also impacted by ethnicity, sexual orientation, and parenting status. Results also indicated a need for continuing attention to the effects of rank, salary equity, sexual harassment, gender discrimination, and decision-making representation in counselor education programs. Results of this study suggested implications for future research in counselor education and counseling.
