Emergence of Complexity from Synchronization and Cooperation

Description: The dynamical origin of complexity is an object of intense debate and, up to moment of writing this manuscript, no unified approach exists as to how it should be properly addressed. This research work adopts the perspective of complexity as characterized by the emergence of non-Poisson renewal processes. In particular I introduce two new complex system models, namely the two-state stochastic clocks and the integrate-and-fire stochastic neurons, and investigate its coupled dynamics in different network topologies. Based on the foundations of renewal theory, I show how complexity, as manifested by the occurrence of non-exponential distribution of events, emerges from the interaction of the units of the system. Conclusion is made on the work's applicability to explaining the dynamics of blinking nanocrystals, neuron interaction in the human brain, and synchronization processes in complex networks.

The emergence of joint attention in a naturalistic parent training program.

Description: Behaviors related to joint attention have been described by behavior analysts and developmental psychologists alike as having a distinctly social function. Children with autism often do not emit these behaviors. Research on the collateral effects of teaching joint attention suggests far reaching consequences. Given the reported benefits of using these behaviors, and the theoretical descriptions of their function, we assessed joint attention as a collateral effect of a naturalistic parent training program. Data suggest that although these behaviors were not directly targeted, they increased in all 3 children. Implications of parent training goals and child intervention targets are discussed in terms of a behavior analysis of joint attention and child development.

The Emergence of Organization Through Communication

Description: Taylor, Cooren, Giroux, and Robichaud (1996) theorize that an organization is created entirely through the interpretations of its members and it evolves as those conversations change. Demonstrating the Taylor et al. theory, the current study focuses on the outcomes of management vision and strategic planning sessions in a division of a large Southwestern University. It explores the ways organization emerges through the discourse of the managers, how text is amplified to support the organization as a whole, the ways organization continues to emerge in communication, and in what ways the emergent view of organization exists throughout the division. The results of the study support the Taylor et al. theory. Management participants created an expanded view of the organization through discourse and then linked it to the university as a whole. Evidence was found supporting continued reformulation but it was limited to the management participants and did not include hourly employees.

The Emergence of the Grotesque Hero in the Contemporary American Novel, 1919-1972

Description: This study shows how the Grotesque Hero evolves from the grotesque victim in selected American novels from 1919 to 1972. In these novels, contradictory forces create a cultural dilemma. When a character is especially vulnerable to that dilemma, he becomes caught and twisted into a grotesque victim. The Grotesque Hero finds a solution to the dilemma, not by escaping his grotesque victimization, but by accepting it and making it work for him. The novels paired according to a particular contradictory dilemma include: Winesburg, Ohio and The Crying of Lot 49, As I Lay Dying and Wise Blood, Miss Lonelyhearts and The Dick Gibson Show, Cabot Wright Begins and Second Skin, The Day of the Locust and The Lime Twig, and Expensive People and The Sunlight Dialogues.

Emergency Physician Communication Style and Career Satisfaction: Is There a Correlation?

Description: The correlation between social style and career satisfaction among emergency physicians was investigated. An e-mail survey was sent to a random sample of 1,000 members of the American College of Emergency Physicians in practice for at least three years; 707 had valid e-mail addresses. A twenty-item behavioral style survey instrument and a five-item career satisfaction scale were used. The study incorporated prenotification and reminder e-mails. Valid responses were obtained from 329 physicians (46.5%). No correlation was shown between social style and career satisfaction. Problems with both survey instruments were discovered. Survey respondents were unhappy with their careers, with an average satisfaction of 4.03, 1 being very satisfied, 5 very dissatisfied. Areas for future study include redoing the study using different survey instruments.

Emerging Ed-tech and Accessibility

Description: Recent developments in the field of education have led to a proliferation of educational technologies (or “ed-tech”), yet access to educational content for students with special needs remains a challenge. This research study aims to assess the current state of accessibility in emerging ed-tech and to identify barriers in enabling educational content to be born accessible. Detailed discussions with various ed-tech platforms revealed less of a need for technical tools, but a more prevailing need for knowledge and education around accessibility – what it means and how best to incorporate accessibility into their platforms. The more experienced teams advocate incorporating accessibility into product development right from the design phase, while the younger teams expressed challenges in navigating accessibility laws and the dire need for easy-to-follow guidelines and best practices. A detailed review of educators' content creation processes reveals multiple dependencies in the ecosystem of ed-tech where partnerships and compatibilities are crucial in enabling accessibility throughout the process. Likewise, an urgent need exists for increasing awareness of accessibility among instructors authoring educational content using emerging ed-tech.

The Emerging Role and Status of the Director of Human Relations in the Desegregation of Selected Public Schools in Texas

Description: The problem of this study was to ascertain the role and status of the specialist in human relations in the desegregation of selected public schools in Texas. Its purpose was to review human relations literature in order to compile a list of representative criteria for human relations programs in industry and to describe the human relations programs and roles of the directors in selected schools. An analysis of available information indicated that industrial organizations have given more attention to human relations programs than have the educational institutions of this country, although their problems have been similar. It was in the workshops of the factories, rather than in the classrooms of America, that social scientists developed human relations skills and techniques. The social issue of desegregation of the races has been a battle often fought on public school campuses. These racial confrontations, coupled with conflicts spawned by the rigidity of traditional schools, have signaled the urgent call for human relations programs to alleviate human problems. The background study included a review of relevant literature, interviews with public school officials, and discussions with state and regional educational administrators. The survey technique was used to collect data for the study. Personal interviews were held with public school officials from five representative districts. The remaining participants responded to mailed questionnaires. The following procedures were used to develop the survey questionnaire: (1) construction of the initial survey questionnaire, (2) selection of a jury panel to validate the questionnaire, (3) validation of the questionnaire, (4) construction of the final questionnaire, and (5) administration of the validated questionnaire.

Emersonian Ideas in Whitman's Early Writings

Description: This thesis will be an attempt to gather together the important ideas set forth in Whitman's early writing which are to be found also in Emerson's lectures, essays, and poems written before 1855. It will attempt to show what Whitman might have gained from Emerson if he had had no other source, and if a creative intellect had not the power of originating its own ideas.

EMG Biofeedback Training: Effect on Behavior of Children with Activity-Level Problems

Description: The relationships between muscle-tension level, motoric-activity level, and academic performance in the laboratory setting are investigated. Three participants were reinforced for reducing and increasing their tension levels, alternately, while engaged in a simulated academic task, and the effects of each on the rate of activity and academic performance were measured. Measures were also obtained on the rate of activity and occurrence of problem behavior in the subject's homes. Significant treatment differences were found which support a direct relationship between tension and activity level so that a decrease in EMG level was associated with a decrease in motoric activity, and an increase in EMG level was associated with an increase in motoric activity. The efficacy of using EMG biofeedback to train relaxation in children with activity-level problems to control their symptoms is supported, especially where such a technique can be used in a specific task-oriented situation.

Emilia Pardo Bazán: Feminism in Her Life and Works

Description: The purpose of this investigation is to show the relationship between the autobiographical information evidenced by the principal female characters in Emilia Pardo Bazan's major novels and her influence on nineteenth-century feminism in Spain. The changing nature of Pardo Bazan's feminism is studied through an analysis of two literary phases in her work. In the first, classified as naturalistic, Pardo Bazan concentrates on the nineteenth century woman and her limited role within society. The second phase reveals a change of perspective as the author creates a character type: this "new woman" is an expression of her feminist beliefs. As Pardo Bazan sought support for feminist goals, diverse intellectual activities characterized her life and became an integral aspect of her art.

Emily and the Child: An Examination of the Child Image in the Work of Emily Dickinson

Description: The primary sources for this study are Dickinson's poems and letters. The purpose is to examine child imagery in Dickinson's work, and the investigation is based on the chronological age of children in the images. Dickinson's small child exists in mystical communion with nature and deity. Inevitably the child is wrenched from this divine state by one of three estranging forces: adult society, death, or love. After the estrangement the state of childhood may be regained only after death, at which time the soul enters immortality as a small child. The study moreover contends that one aspect of Dickinson's seclusion was an endeavor to remain a child.

Emotional Alienation a Consistent Factor in Ecological and Chronic Pain Patients

Description: The purpose of the present study was to determine the extent of emotional alienation consistent with ecological and chronic pain patients and to assess differences on this dimension between these two patient populations. Ecological group included 100 ecological inpatients, chronic pain group, 30 spinal pain clinic patients. Tests administered were the Sixteen Personality Factor (16 PF) and the Minnesota Multiphasic Personality Inventory (MMPI) including Harris and Lingoes subscales. The ecological group was significantly higher on measures of alienation than the pain group or the standardization population. Results also indicated that the ecological group demonstrated more psychopathology. Emotional alienation appeared to be a consistent stressor in ecological and chronic pain patients. Treatment of these patients should include the reduction of this emotional correlate.

Emotional and Cognitive Coping in Relationship Dissolution

Description: Romantic relationships are important for social development and can impact an individual’s functioning both positively and negatively, especially when the relationship breaks up. Emotional and cognitive coping strategies including emotion approach coping, avoidance, and rumination and variable response to expressive writing intervention were examined in relation to post-dissolution distress. Undergraduate participants randomized into two groups completed measures of cognitive and emotional coping variables and global distress, with the experimental group completing a three-session expressive writing protocol. Writing samples were rated for processing mode, or the degree of vague general statements. Avoidance and rumination demonstrated significant cross-sectional associations with Time 1 distress controlling for demographics and characteristics of the former relationship. Gender moderated the relationship between rumination and distress. Using a matched sub-sample, the groups did not differ on emotional coping variables or distress. Results demonstrate the importance of examining emotional coping strategies in conjunction with relationship dissolution.

Emotional/Behavioral Disturbance and Speech/Language Disorders: Prevalence of the Dual Diagnoses in a School-Age Population

Description: The purpose of this study was to examine the prevalence of the comorbidity of emotional/behavioral disorders (EBD) and speech/language disorders among those students identified as under The Individuals With Disabilities Education Act criteria as emotionally disturbed and speech impaired. The literature reviewed included clinical and school settings that examined a cooccurrence of language disorders in the EBD population. Other research reported a lack of routine involvement of speech/language therapists in the assessment of the EBD population. Implications from clinical studies suggested a need for greater attention to language disorders in a multi- and interdisciplinary assessment. This study investigated the prevalence of the dual occurrence of EBD and speech/language disorders in Grades 2 through 6 in Texas schools in light of the known research. Relationships in ethnicity and socioeconomic status were examined using chi-square test of independence. Aggregate data were obtained from the database of the Texas Pupil Information Management System and from survey questionnaire responses provided by speech therapists in selected districts. The literature review focused on the impact of language in the development of appropriate personal interactions and communication skills, especially those relevant to pragmatic language factors and the implications of language competency in successful personal living and career roles and supported the importance of language as an important contributor to a person's life success and the correlation of EBD disabilities and speech/language disorders. Social skills instruction, the relationship of language, especially pragmatics, and social competencies for this population are included. The results revealed a relationship between ethnicity and speech/language disorders among the students identified with EBD. In considering the population of students identified as EBD and language disordered, a significant relationship was found between ethnicity and socioeconomic status. Recommendations include suggestions for future research, assessment procedures, classroom interventions, and data collection methods.

An Emotional Business: the Role of Emotional Intelligence in Entrepreneurial Success

Description: Successful entrepreneurial activity is important for a healthy economy and can be a major source of job creation. While the concept of entrepreneurship has been around for quite some time, researchers continue to explore the factors that underlie entrepreneurial performance. Specifically, researchers have sought to further examine why some entrepreneurial ventures are more successful than others. the concept of emotional intelligence (EI) has gained the attention of researchers and practitioners alike. Practitioners have realized that employees can no longer be perceived as biological machines that are capable of leaving their feelings, norms, and attitudes at home when they go to work. Researchers are embracing the concept of emotional intelligence because of its relationship with efficiency, productivity, sales, revenues, quality of service, customer loyalty, employee recruitment and retention, employee commitment, employee health and satisfaction, and morale. While there is considerable evidence documenting the effects of emotional intelligence on leadership performance, job performance in large firms, and educational performance, very little research has examined how emotional intelligence affects entrepreneurial performance and the variables that account for this relationship. Individuals in entrepreneurial occupations face business situations that necessitate unique skills and abilities in social interactions. Emotional intelligence has implications for entrepreneurial situations and social interactions such as negotiation, obtaining and organizing resources, identifying and exploiting opportunities, managing stress, obtaining and maintaining customers, and providing leadership. the primary purpose of this study is to investigate emotional intelligence in the context of entrepreneurship. in addition, the study will shed light on the mediating effects of individual competencies, organizational tasks, and the environmental culture and climate. the results of the study provide insights for emotional intelligence researchers, entrepreneurship researchers, individuals with entrepreneurial aspirations, academic institutions, as well as government and financial entities that provide resources to new ventures.
