Medication adherence among the elderly: A test of the effects of the Liberty 6000 technology. (open access)

Medication adherence among the elderly: A test of the effects of the Liberty 6000 technology.

Medication adherence is a formidable challenge for the elderly who may have several prescribed medications while dealing with limited incomes and declining health. The primary purpose of this study was to evaluate the Liberty 6000, an automated capsule and tablet dispenser that provides proper medication dosages and is intended to encourage and track medication adherence. Seven focus groups were assembled; these comprised 49 men and women ages 65 to 98 years of Black, Anglo, and Hispanic descent who met the following criteria: living independently or semi-independently, had suffered one or more impairments, and were taking at least three prescription medications. Each focus group session lasted 90 minutes and was tape-recorded and transcribed verbatim, resulting in about 2,600 lines of text. Each question was designed to be open-ended to avoid introducing any bias that might influence the response. The Health Belief Model conceptually guided the study that addressed perceptions of illness susceptibility and severity, barriers, benefits, and cues to action associated with medication adherence. Main benefits of taking medications included avoiding inherited illnesses (or tendencies for illnesses), and reducing illness symptoms. Barriers to taking medications included forgetting, dexterity problems, and high cost. Benefits of the proposed intervention included reminding, caregiver notification, …

Aesthetic Models and Structural Features in Concerto for Solo Percussion and Concert Band (open access)

Aesthetic Models and Structural Features in Concerto for Solo Percussion and Concert Band

Concerto for Solo Percussion and Concert Band was commissioned by Staff Sergeant Rone Sparrow, a percussionist with the West Point Military Academy Band. Funding for the project was provided by the Barlow Foundation. The piece was premiered April 13, 2005 in the Eisenhower Hall Theater at West Point, New York. Rone Sparrow performed with the USMA band, and Colonel Thomas Rotondi Jr., Commander/Conductor, conducted the piece. The concerto consists of three movements, and each movement features a different instrument: the first features marimba, the second, vibraphone, and the third movement features the drum kit together with a rhythm section (piano, bass, and drums). In addition to the piece, the dissertation paper discusses important technical detail related to the piece, including: harmony, form, rhythm, programmatic ideas as they relate to motivic strands, and the process of generating and discarding material. The paper also focuses on a number of factors that were influential to the piece, such as postmodern philosophy.

The Effect of SFAS No. 141 and SFAS No. 142 on the Accuracy of Financial Analysts' Earnings Forecasts after Mergers (open access)

The Effect of SFAS No. 141 and SFAS No. 142 on the Accuracy of Financial Analysts' Earnings Forecasts after Mergers

This study examines the impact of Statements of Financial Accounting Standards No. 141 and No. 142 (hereafter SFAS 141, 142) on the characteristics of financial analysts' earnings forecasts after mergers. Specifically, I predict lower forecast errors for firms that experienced mergers after the enactment of SFAS 141, 142 than for firms that went through business combinations before those accounting changes. Study results present strong evidence that earnings forecast errors for companies involved in merging and acquisition activity decreased after the adoption of SFAS 141, 142. Test results also suggest that lower earnings forecast errors are attributable to factors specific to merging companies such as SFAS 141, 142 but not common to merging and non-merging companies. In addition, evidence implies that information in corporate annual reports of merging companies plays the critical role in this decrease of earnings forecast error. Summarily, I report that SFAS 141, 142 were effective in achieving greater transparency of financial reporting after mergers. In my complementary analysis, I also document the structure of corporate analysts' coverage in "leaders/followers" terms and conduct tests for differences in this structure: (1) across post-SFAS 141,142/pre-SFAS 141, 142 environments, and (2) between merging and non-merging firms. Although I do not identify …

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

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

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 …

The school reform movement and high stakes standardized testing: An analysis of factors impacting the academic outcomes of students receiving special education services.

The purpose of this study was to investigate special education outcomes in relation to state standardized testing. It specifically sought to determine if a relationship existed between selected data from the Texas Academic Excellence Indicator System (AEIS) comparing district students receiving special education services TAAS scores with selected district demographic, fiscal, and special education data. The population for this study consisted of all 2001-2002 grades 3-8 and 10 public school students with the exception of charter schools, special-purpose statutory districts, and state-administered districts. The reading analysis incorporated data from 896 Texas school districts. The mathematics analysis used data from 914 school districts. Multiple linear hierarchical regression was chosen as the method for statistical analysis. Data was obtained from the Texas Education Agency (TEA) as a special data pull. For both the reading and mathematics analyses, wealth and ethnicity were statistically insignificant although ethnicity individually accounted for a large percentage of the variance for both the reading (20.3%) and mathematics (13.2%) scores as well as producing negative β weights. All other predictor variables produced varying degrees of statistical significance. Community type, socioeconomic status, instructional expenditures per students, and instructional expenditures per student receiving special education services also produced negative β weights. …

Primary revenue streams of Hispanic-serving community colleges in Texas. (open access)

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

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.

Treatment Outcomes Related to EEG-Biofeedback for Chemical Dependency: Changes in MMPI-2™ (University of Minnesota) Personality Measures and Long Term Abstinence Rates (open access)

Treatment Outcomes Related to EEG-Biofeedback for Chemical Dependency: Changes in MMPI-2™ (University of Minnesota) Personality Measures and Long Term Abstinence Rates

Peniston and Kulkosky (1989, 1990) demonstrated the effectiveness of alpha-theta EEG-Biofeedback (EEG-BFB) in treating inpatient alcoholics noting significant improvements in depression, psychopathology, serum β-endorphin levels, and abstinence rates. The present study is an extension of a previously unpublished replication of the Peniston EEG-BFB protocol with 20 chemically dependent outpatients (Bodenhamer-Davis, Callaway, & DeBeus, 2002). Fifteen subjects were "high risk for re-arrest" probationers. Data for the EEG-BFB group was collected from archival records. Subjects completed an average of 39 sessions (SD = 6.096), with 33 of those being EEG-BFB. Pre/post-treatment MMPI-2s™ (University of Minnesota) were collected and follow-up (4-11 years) data obtained (abstinence rates, re-arrests in some cases). Treatment effects were evaluated by comparing assessment data (pre/post) and documenting abstinence rates. Post-treatment MMPI-2 results were within normal limits, with several scales significantly reduced from baseline suggesting less psychopathology. Results were then compared to 20 subjects receiving standard addiction treatment (OT-CD group), but not EEG-BFB. OT-CD subjects completed a 2-week inpatient program followed by 18 outpatient sessions. Pre/post assessment and follow-up data was collected on the OT-CD group. The OT-CD group's post-assessment results showed three elevations (MMPI-2 scales 4/6/8), suggestive of characteriological problems. Post-MMPI-2 results of the two groups were compared via …

Charge Interaction Effects in Epoxy with Cation Exchanged Montmorillonite Clay and Carbon Nanotubes. (open access)

Charge Interaction Effects in Epoxy with Cation Exchanged Montmorillonite Clay and Carbon Nanotubes.

The influence of charge heterogeneity in nanoparticles such as montmorillonite layered silicates (MLS) and hybrid systems of MLS + carbon nanotubes was investigated in cured and uncured epoxy. Epoxy nanocomposites made with cation-exchanged montmorillonite clay were found to form agglomerates near a critical concentration. Using differential scanning calorimetry it was determined that the mixing temperature of the epoxy + MLS mixture prior to the addition of the curing agent critically influenced the formation of the agglomerate. Cured epoxy samples showed evidence of the agglomerate being residual charge driven by maxima and minima in the concentration profiles of thermal conductivity and dielectric permittivity respectively. A hybrid nanocomposite of MLS and aniline functionalized multi walled nanotubes indicated no agglomerates. The influence of environmentally and process driven properties on the nanocomposites was investigated by examination of moisture, ultrasound, microwaves and mechanical fatigue on the properties of the hybrid systems. The results point to the importance of charge screening by adsorbed or reacted water and on nanoparticulates.

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

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

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 …

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

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.

Character Education Programs and Student Suspension Rates from School: Do Character Education Programs Decrease Student Suspensions from Regular Instructional Public Elementary Schools in Texas?

The purpose of this study was to determine if character education programs impact the suspension rates of students from regular instructional public elementary schools in Texas. The data was also examined to determine if the number of years since a school's implementation of a character education program has an impact on the effectiveness of the programs as measured by the suspension rates of students from school. Finally, the study sought to determine if the socio-economic status of the schools has an impact on the effectiveness of character education programs as measured by the student suspension rates. A random sample of 135 regular instructional public elementary schools in Texas was collected. The principal of each school completed a questionnaire that was used to sort schools into three groups: schools with "direct" character education programs, schools with "indirect" character education programs, and schools that have implemented no type of character education program. A two-year history of suspensions was obtained for each school. The data was analyzed using one-way and two-way ANOVAs. The results of the analyses indicated that the implementation of character education programs, no matter what type, did not produce statistically significant differences in student suspension rates from school.

Dynamics, Thermodynamic formalism and Perturbations of Transcendental Entire Functions of Finite Singular Type (open access)

Dynamics, Thermodynamic formalism and Perturbations of Transcendental Entire Functions of Finite Singular Type

In this dissertation, we study the dynamics, fractal geometry and the topology of the Julia set of functions in the family H which is a set in the class S, the Speiser class of entire transcendental functions which have only finitely many singular values. One can think of a function from H as a generalized expanding function from the cosh family. We shall build a version of thermodynamic formalism for functions in H and we shall show among others, the existence and uniqueness of a conformal measure. Then we prove a Bowen's type formula, i.e. we show that the Hausdorff dimension of the set of returning points, is the unique zero of the pressure function. We shall also study conjugacies in the family H, perturbation of functions in the family and related dynamical properties. We define Perron-Frobenius operators for some functions naturally associated with functions in the family H and then, using fundamental properties of these operators, we shall prove the important result that the Hausdorff dimension of the subset of returning points depends analytically on the parameter taken from a small open subset of the n-dimensional parameter space.

Assessing Allied Health and Nursing Post-Secondary Career and Technical Education Teacher Attitudes and Beliefs About Reading (open access)

Assessing Allied Health and Nursing Post-Secondary Career and Technical Education Teacher Attitudes and Beliefs About Reading

This study examined allied health and nursing career and technical education (CTE) teacher beliefs and attitudes about reading. Since beliefs and attitudes influence the way teachers teach, it is important to understand what those beliefs and attitudes are, especially in relationship to reading in subject matter classrooms. One hundred twelve individuals responded to a written survey concerning their attitudes and beliefs about reading. A four-factor solution was achieved with a principal components factor analysis. A significant number of variables were associated with the factor labeled Reading Apathy, which appears to be indicative of the condition known as aliteracy among faculty who participated in the study. Professional development activities grounded in novice-to-expert theory are suggested as a way of overcoming the phenomenon. Recommendations for future research involve a more detailed study to further characterize the condition of aliteracy and its impact on student learning.

Chemistry, Detection, and Control of Metals during Silicon Processing

This dissertation focuses on the chemistry, detection, and control of metals and metal contaminants during manufacturing of integrated circuits (ICs) on silicon wafers. Chapter 1 begins with an overview of IC manufacturing, including discussion of the common aqueous cleaning solutions, metallization processes, and analytical techniques that will be investigated in subsequent chapters. Chapter 2 covers initial investigations into the chemistry of the SC2 clean - a mixture of HCl, H2O2, and DI water - especially on the behavior of H2O2 in this solution and the impact of HCl concentration on metal removal from particle addition to silicon oxide surfaces. Chapter 3 includes a more generalized investigation of the chemistry of metal ions in solution and how they react with the silicon oxide surfaces they are brought into contact with, concluding with illumination of the fundamental chemical principles that govern their behavior. Chapter 4 shows how metal contaminants behave on silicon wafers when subjected to the high temperature (≥ 800 °C) thermal cycles that are encountered in IC manufacturing. It demonstrates that knowledge of some fundamental thermodynamic properties of the metals allow accurate prediction of what will happen to a metal during these processes. Chapter 5 covers a very different but …

The implementation of international education in colleges and universities in the state of Texas: A follow-up study.

This study is a follow-up to a study completed by Dr. Thomas Barker in 1994 entitled The Status of the Implementation of International Education in Texas Four-year Colleges and Universities: A Comprehensive Study. A survey of 35 Texas universities and 6 out-of-state benchmark universities revealed information regarding the international programs at these universities in four areas. The four areas surveyed include: (a) administrative, (b) instructional, (c) international student support services, and (d) outreach. A summary of the survey results includes 34 tables detailing the university responses for the 2004 survey compared with the responses obtained from the original, Barker (1994). The results from the 2004 participating benchmark institutions were also reviewed. Texas universities continue to work toward the internationalization of the curriculum with increased numbers supporting an international focus in their mission statements and staffing patterns. Benchmark institutions continue to lead Texas institutions in a majority of areas surveyed. Funding for international education continues to be an issue for both the benchmark and Texas institutions. Changes in attitudes and immigration policies continue to affect the implementation of international programs on the university level. While universities continue to provide support to community and businesses in the area of international education, the …

Quality of work environment for counselor education faculty.

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.

A Comparative Analysis of Style of User Interface Look and Feel in a Synchronous Computer Supported Cooperative Work Environment

The purpose of this study is to determine whether the style of a user interface (i.e., its look and feel) has an effect on the usability of a synchronous computer supported cooperative work (CSCW) environment for delivering Internet-based collaborative content. The problem motivating this study is that people who are located in different places need to be able to communicate with one another. One way to do this is by using complex computer tools that allow users to share information, documents, programs, etc. As an increasing number of business organizations require workers to use these types of complex communication tools, it is important to determine how users regard these types of tools and whether they are perceived to be useful. If a tool, or interface, is not perceived to be useful then it is often not used, or used ineffectively. As organizations strive to improve communication with and among users by providing more Internet-based collaborative environments, the users' experience in this form of delivery may be tied to a style of user interface look and feel that could negatively affect their overall acceptance and satisfaction of the collaborative environment. The significance of this study is that it applies the technology …

An integrative investigation of person-vocation fit, person-organization fit, and person-job fit perceptions. (open access)

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

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 …

A Comparison of Academic Achievement of Economically Disadvantaged Elementary Students Served in Title I Part A Programs: Targeted Assistance Versus Schoolwide Models

This study analyzed test scores of economically disadvantaged students who attended two elementary schools implementing different types of Title I models from 1999-2001. Test scores from the Texas Assessment of Academic Skills (TAAS), the Iowa Test of Basic Skills (ITBS) and the Stanford Achievement Test (SAT-9) were analyzed. One school implemented the targeted assistance model (less than 50% poverty), which focused resources on students were identified as failing or at risk of failing. The other a schoolwide model (95% poverty), which used resources to help all students in a school regardless of whether they ware failing, at risk of failing, or economically disadvantaged. The quantitative approach was used with a causal comparative design. A cohort of continuously enrolled students was identified for the TAAS (n=169 and 189) and the ITBS/SAT-9 (n=49 and 87). Descriptive statistics such as the frequency, mean, and standard deviation, were used to measure differences on the Texas Learning Index (TLI) for the TAAS, and Normal Curve Equivalent (NCE) on the ITBS/SAT-9. Analysis of covariance (ANCOVA) was used to partially adjust for preexisting differences among the groups and because randomization was not possible. The independent variable was type of Title I model, targeted assistance or schoolwide. The …

This study had two primary purposes. The first goal was to bring the 1993/1996 Katsinas-Lacey two-year college classification system into the 21st century using data from the 2000 United States Census and the National Center for Education Statistics' Integrated Postsecondary Educational Data System (IPEDS) surveys for the 2000-2001 and 2001-2002 academic years. The second goal was to create a descriptive portrait of the universe of two-year, publicly controlled institutions that primarily offer the associate's degree mapped against the updated classification system and to describe and discern similarities and differences within this particular population by class and subclass in terms of multiple measurable characteristics for which IPEDS data were available. The study, based upon classification theory utilized in social science and management sciences - particularly the work of Bailey and McKelvey - assessed the efficacy of a number of other recent proposed community college classification systems, the original Katsinas-Lacey system and the revised version of Katsinas-Lacey created through the current research. It found both the original Katsinas-Lacey system and the revised version to meet the criteria for a well-made classification model.

The Improvisational Vocabulary of Pepper Adams: A Comparison of the Relationship of Selected Motives to Harmony in Four Improvised Solos

Park "Pepper" Adams, III (1930-1986) is one of the most influential baritone saxophonists in the history of modern jazz. In addition to his time feel, his timbre, and other conceptual techniques, a great deal of Adams's improvisational style and vocabulary can be illustrated by his use of three motivic devices. These three motivic devices are: (1) his utilization of the sixth degree of the major scale as an important melodic pitch; (2) his use of a paraphrased portion of the melody of the popular song "Cry Me a River;" and (3) his use of the half-whole octatonic scale when the rhythm section sounds a dominant chord. This dissertation traces the way in which Adams applies these three motivic devices through four of his original compositions, "Enchilada Baby," "Bossallegro," "Lovers of Their Time," and "Rue Serpente." All four of these compositions were recorded by Adams on his 1980 album, The Master. In addition to the motivic analysis, a biography of Adams is included. Complete transcriptions by the author of Adams's improvised solos on the four compositions are included in the appendices.

Privacy Concerns and Personality Traits Influencing Online Behavior: A Structural Model (open access)

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

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.

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

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) …
