The effects of multiple interventions in organizational development change were studied in a comprehensive meta-analytic review. Thirteen organizational interventions were assessed on five outcome variables based upon previous research of six major meta-analytic reviews. Findings based on 138 studies indicated that there were no significant effects of multiple interventions on positive organizational change as opposed to individually implemented interventions. The findings are not congruent with previous findings of organizational development change, and possible issues surrounding these differences are discussed.

Organizational change and development (OCD) has been studied by researchers to identify the effectiveness of change initiatives. Because of the broad scope of interventions in OCD, these studies have covered a range of areas including multiple interventions and the methodological rigor used by researchers. However, few have looked at organizational versus individual change within an organization, to examine whether individual change is more effective than organizational change. The purpose of this study is to determine if organizational change occurs in a top down or bottom up manner. A meta-analysis was conducted using 238 field experiments. Each study was coded for intervention and organizational outcome and for individual or organizational level variables. Effect sizes were calculated for each study, each level, and each level by intervention and outcome measure. Results indicate that while OCD interventions overall had a moderate effect size, the level of intervention or outcome was not a moderating variable.

This study investigated if the use of a team feedback system resulted in peers perceiving a change in behavior. Personality variables such as conscientiousness, agreeableness, and extraversion were examined as possible moderators. Self-ratings and peer ratings were collected from 164 individuals through the use of the Center for Collaborative Organizations' Team Feedback System. Using polynomial regression, it was determined that time 1 peer ratings predicted behavior change and the combination of conscientiousness variables moderated peer perceived behavior change.

Six serial focus groups were used to explore the perceptions of postpartum depression among nine adolescent mothers. The discussions were tape recorded, transcribed and analyzed using symbolic interaction theory, specifically Goffman's concept of stigma. Participants identified major stigma themes in relation to postpartum depression, teenage pregnancy and motherhood, all of which were portrayed negatively in the media. Several key causes of adolescent postpartum depression were also found including self esteem relating to poor body image and social support. The findings indicate a much needed change in the way adolescent mothers are identified and treated for postpartum depression. Additionally, the importance of social support in preventing and treating adolescent postpartum depression is highlighted and programs addressing such concerns must be implemented.

Award-winning composer John Musto stands at the forefront of modern American art-song composition. Many of his songs, such as "Litany" from Shadow of the Blues, have already achieved a place in the standard contemporary repertory for singers. His compositional technique weaves influences of jazz, blues, ragtime, and popular music with classical technique to make music that is decidedly modern but accessible and well liked both by critics and audiences. Unfortunately, though he is still actively composing, very little has been written about Musto and there is a lack of information available about his more recent compositions. This performance guide addresses one of Musto's acclaimed song cycles, Penelope, (a cycle of seven songs for soprano and piano) commissioned and premiered in 2000. The story of the cycle is an updated version of the character Penelope from Homer's The Odyssey and was a collaboration between Musto and poet Denise Lanctot. Including interviews with Musto, and his wife, soprano Amy Burton, who premiered the cycle and for whom it was written, the document provides background information on how the cycle was conceived and gives in-depth performance information on each of the seven songs of Penelope. In addition to musical examples and poetry from …

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 …

People living with HIV/AIDS (PLH) struggle with depression. Recent research suggests that depression affects medical regimen adherence, disease progression, and risky sexual behaviors. The present study uses a stress and coping theory viewing HIV-related stigma and physical symptoms as stressors in PLH. Results suggest whereas symptoms and stigma consistently predict negative affect, positive affect, and overall depression, the role of optimism, pessimism, active coping, denial, and behavioral disengagement is not as clear. Pessimism and denial predict negative affect and depression. Optimism and behavioral disengagement predict depression and positive affect. Active coping only predicts positive affect. Focusing on positive and negative affect as distinct components that contribute to overall depression may help researchers develop interventions more effectively.

Prairie Gothic is rich in Texas history. It is the story of Erickson s family, ordinary people who, through strength of character, found dignity in the challenges presented by nature and human nature. It is also the story of the place instrumental in shaping their lives the flatland prairie of northwestern Texas that has gone by various names (High Plains, South Plains, Staked Plains, and Llano Estacado), as well as the rugged country on its eastern boundary, often referred to as the caprock canyonlands. One branch of Erickson’s family arrived in Texas in 1858, settling in Parker County, west of Weatherford. Another helped establish the first community on the South Plains, the Quaker colony of Estacado. They crossed paths with numerous prominent people in Texas history: Sam Houston, Sul Ross, Charles Goodnight, Cynthia Ann and Quanah Parker, Jim Loving, and a famous outlaw, Tom Ross. Erickson’s research took him into the homes of well-known Texas authors, such as J. Evetts Haley and John Graves. Graves had written about the death of Erickson s great-great grandmother, Martha Sherman. The theme that runs throughout the book is that of family, of four generations’ efforts to nurture the values of civilized people: reverence …

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 …

This study explored public safety programs in publicly controlled American community colleges. The need for accurate and complete information in an era of homeland security and defense is paramount as government, education, the private sector, and the citizenry interact to ensure a safer nation. The general purposes of this study were to compile current descriptive information on public safety programs and curricula in America's publicly controlled community colleges, and to identify problems and prospects inherent in the administration of these programs. Information is critical as community colleges continue to struggle with decreased funding and seek alternative sources of revenue. Community colleges represent a tremendous network for course delivery, such as homeland security training, but struggle to obtain the attention or the funding from the federal government. A review of pertinent literature provided the foundation of a 100-item survey questionnaire that was mailed to a random sample of 200 public safety administrators at American community colleges. The study also included a review of archival data to further describe the programs. Of the 200 instruments sent, 97 (48.5%) were completed, returned, and useable. From the literature, the survey results, and the archival data, a comprehensive list of community colleges with public safety …

Pseudomonas aeruginosa is a Gram-negative rod, aerobic, non-fermenting, oxidase positive, pigment producing, and nutritionally versatile bacterium. Infections by P. aeruginosa are the most important cause of morbidity and mortality in immunocompromised patients, given virulence factor production that suppresses antibiotic therapy and promotes persistent infection. This research is the first comprehensive report of the pyrimidine biosynthetic pathway for all phases of growth in minimal and rich media coupled with the evaluation of virulence factor production of P. aeruginosa in comparison to four other bacterial species (Pseudomonas putida, Pseudomonas fluorescens, Burkholderia cepacia, and Escherichia coli wild-type strains). Cellular growth and passing genetic information to the next generation depend on the synthesis of purines and pyrimidines, the precursors of DNA and RNA. The pyrimidine biosynthetic pathway is essential and found in most organisms, with the exception of a few parasites that depend upon the pyrimidine salvage pathway for growth. Both the pyrimidine biosynthetic and salvage enzymes are targets for chemotherapeutic agents. In our laboratory, research on pyrimidine auxotrophic mutants showed the role of the pyrimidine biosynthetic pathway and its intermediates on P. aeruginosa metabolism and impaired virulence factors production. The present research shows that pyrimidine enzymes are active in all phases of growth, …

The purpose of this dissertation is two-fold: one is to analyze the narratives of Acis and Galatea written by Ovid, and the two libretti by Handel's librettists including Nicola Giuvo (1708) and John Gay (1718) with John Hughes and Alexander Pope; the other is to correlate this textual analysis within the musical languages. A 1732 pastiche version is excluded because its bilingual texts are not suitable for the study of relationships between meaning and words. For this purpose, the study uses the structural theory- -mainly that of Gérard Genette--as a theoretical framework for the analysis of the texts. Narrative analysis of Acis and Galatea proves that the creative process of writing the libretto is a product of a conscious acknowledgement of its structure by composer and librettists. They put the major events of the story into recitative and ensemble. By examining the texts of both Handel's work, I explore several structural layers from the libretti: the change of the characterization to accommodate a specific occasion and the composer's response to contemporary English demand for pastoral drama with parodistic elements, alluding to the low and high class of society. Further, Polyphemus is examined in terms of relationships with culture corresponding to …

The relationships between sociometric status and selected performance variables for counselors in training were investigated. Gender differences in sociometric status were also investigated. Research participants were master's level counseling students. The point-biserial correlation coefficient was used to determine the relationship between sociometric status and grades. The SPSS 13.0 crosstabulation procedure was used to examine gender differences in sociometric status. The results indicated a moderate relationship between sociometric status and grades earned in a group counseling course. A small to negligible relationship between sociometric status and pre-practicum and practicum grades was found. No gender difference in sociometric status was found. The study provides some support for the use of sociometric measurements in predicting group counseling performance, but more research is needed.

Adherent Cu films were electrodeposited onto polycrystalline W foils from purged solutions of 0.05 M CuSO4 in H2SO4 supporting electrolyte and 0.025 M CuCO3∙Cu(OH)2 in 0.32 M H3BO3 and corresponding HBF4 supporting electrolyte, both at pH = 1. Films were deposited under constant potential conditions at voltages between -0.6 V and -0.2 V versus Ag/AgCl. All films produced by pulses of 10 s duration were visible to the eye, copper colored, and survived a crude test called "the Scotch tape test", which involves sticking the scotch tape on the sample, then peeling off the tape and observing if the copper film peels off or not. Characterization by scanning electron microscopy (SEM)/energy dispersive X-ray (EDX) and X-ray photon spectroscopy (XPS) confirmed the presence of metallic Cu, with apparent dendritic growth. No sulfur impurity was observable by XPS or EDX. Kinetics measurements indicated that the Cu nucleation process in the sulfuric bath is slower than in the borate bath. In both baths, nucleation kinetics does not correspond to either instantaneous or progressive nucleation. Films deposited from 0.05 M CuSO4/H2SO4 solution at pH > 1 at -0.2 V exhibited poor adhesion and decreased Cu reduction current. In both borate and sulfate baths, small …

Comprising many airplanes, airports, aircrew, and employees, aviation industry is a large sector that is very vulnerable to attacks, whether it is from terrorists or criminals. Aviation history is fraught with examples of airport bombings, hijackings, and sabotage terrorist attacks. The most destructive of which is the tragedy of September 11, 2001, the cornerstone of today's aviation security policies. This study uses risk assessment tools to determine the dimensions of danger and threats against the aviation industry and addresses how vulnerable the aviation sector is. After vulnerabilities and threats are examined, possible impacts of attacks against the aviation security are discussed. This study also explores the pre and post September 11 policies that governments and policy makers develop to reduce risks in aviation sector. In addition, it discusses weaknesses and strengths of these policies which surfaced during the implementations. Finally, this study proposes some recommendations based on vulnerabilities and threats of aviation security.

This study evaluated the effectiveness of a procedure for teaching a caregiver to shape vocal language in a young child with autism. A multiple baseline design was employed to assess caregiver use of shaping procedures, child vocal language progress, and the social validity of the procedures. Following baseline and introductory sessions, the coach and caregiver reviewed video from the previous session and the coach gave descriptive feedback to the caregiver about her performance. Following the review of the videotaped segment, procedures to increase skills were selected and practiced. Rates of responsive opportunity arrangement, model presentation, responsive model delivery, and responsive event delivery, as well as the child's rate of requests, vocalizations, diversity of vocalizations, and social validity were measured. Data suggested that the procedures effectively taught the skill of shaping to a caregiver, which in turn seemed to produce increases in the child's vocal responding.

In Spartan Band (coined from a chaplain’s eulogistic poem) author Thomas Reid traces the Civil War history of the 13th Texas Cavalry, a unit drawn from eleven counties in East Texas. The cavalry regiment organized in the spring of 1862 but was ordered to dismount once in Arkansas. The regiment gradually evolved into a tough, well-trained unit during action at Lake Providence, Fort De Russy, Mansfield, Pleasant Hill, and Jenkins' Ferry, as part of Maj. Gen. John G. Walker's Texas division in the Trans-Mississippi Department. Reid researched letters, documents, and diaries gleaned from more than one hundred descendants of the soldiers, answering many questions relating to their experiences and final resting places. He also includes detailed information on battle casualty figures, equipment issued to each company, slave ownership, wealth of officers, deaths due to disease, and the effects of conscription on the regiment’s composition. “The hard-marching, hard-fighting soldiers of the 13th Texas Cavalry helped make Walker’s Greyhound Division famous, and their story comes to life through Thomas Reid’s exhaustive research and entertaining writing style. This book should serve as a model for Civil War regimental histories.”—Terry L. Jones, author of Lee’s Tigers

A growing number of individuals with special needs are discovering the benefits of therapies and activities involving horseback riding. Special Needs, Special Horses , by Naomi Scott, offers information about the amazing results possible with therapeutic riding, or hippotherapy. From recreational riding for individuals with disabilities, to the competitions some riders enter (and win), Scott describes the various techniques of the process and its benefits to the physically and mentally challenged. The book explores the roles of the instructors, physical therapists, volunteers, and the horses, and explains carriage driving, vaulting, and educational interactions with horses. Scott profiles individuals involved in the therapy, including clients whose special needs arose from intrauterine stroke, cerebral palsy, transverse myelitis, Parkinson’s disease, paralysis, sensory integration dysfunction, multiple sclerosis, shaken baby syndrome, sensory damage, stroke, seizures, infantile spasms, Down syndrome, and autism. Special Needs, Special Horses is an excellent guide for the families of the many who do—or could—enjoy improved lives from therapeutic riding. It will also appeal to practitioners of therapeutic riding as an overview of their profession.

William Grant Still's musical achievements are legion. Because he was the first African American to break the color line in America's concert halls, Still earned the sobriquet "Dean of Negro Composers." Paradoxically, Still's reception suffers from this list of "firsts." The unintended consequence of cataloging his achievements venerates his position as an iconoclast while detracting critical attention from his music. Conversely, if we ignore the social context in which Still produced his music, we risk misinterpreting his compositional choices or trivializing the significance of his accomplishments prior to the Civil Rights Movement in America. Still's so-called symphonic trilogy-Africa, Symphony No. 1 ("Afro-American"), and Symphony No. 2 ("Song of a New Race")-is the subject of an intertextual analysis that demonstrates how extra-musical concerns, such as race, and musical elements can be brought into alignment. Chapter one discusses black music scholarship in general and Still scholarship in particular by tracing the development of black music historiography. The second chapter explores one of the various modes of inquiry used to study black music-intertextuality. The context for Still's self-titled racial and universal periods is the subject of chapter three. For the first time, arguments from both sides of the racial divide are reconsidered in …

Stories: Spain, Lovers and Crazy Old Ladies is a collection of short stories about relationships, traumas, memories and change.

Numerous troponin T (TnT) isoforms are generated by alternative RNA splicing primarily in its NH2-terminal hypervariable region, but the functions of these isoforms are not completely understood. In this dissertation work, calcium and terbium binding behavior of several forms of TnT were investigated by spectroscopic and radioactive techniques. Chicken breast muscle TnT binds calcium and terbium through its NH2-terminal Tx motif (HEEAH)n with high affinity (10-6 mM) and fast on-rate (106 - 107 M-1 s-1). Chicken leg muscle TnT and a human cardiac TnT NH2-terminal fragment, which both lack the Tx motif on their NH2-terminal regions, do not have affinities for calcium in the physiological range. Computational predictions on TnT N47 suggest that the TnT NH2-terminal region might fold into an elongated structure with at least one high affinity metal ion binding pocket comprised primarily of the Tx motif sequence and several lower affinity binding sites. In addition, calcium binding to TnT N47 might alter its conformation and flexibility. Luminescence resonance energy transfer measurements and other experimental observations are consistent with the computational predictions suggesting the computational simulated atomic model is reasonable. TnT mutations are responsible for 15% of familiar hypertrophic cardiomyopathy (FHC) cases with a phenotype of relatively mild …

Trained musicians cannot use the same breath process in daily living as for singing. Also, the normal breath cycle applied to speech is not efficient. Therefore, students who are learning to sing need to know proper breathing techniques. In this thesis, I will describe the breathing process and the correct way to breathe while singing, based on studies of four American pedagogues; Appleman, Reid, Vennard and Miller. To understand the breathing process for singing, it is necessary to study and understand the anatomical system and the mechanics of the respiratory system. Therefore, the first chapter contains anatomical system of breath management. Then, in the second chapter, the specific breath management techniques of four American pedagogues will be examined and compared. Three of them, Appelman, Vennard, and Miller, suggested some exercises in order to develop correct and efficient breathing habits.
