Toward the Identification of a Body of Classic or Seminal Works in Adult Education: a Citation Analysis

Toward the Identification of a Body of Classic or Seminal Works in Adult Education: a Citation Analysis

Date: December 1989
Creator: Newcomer, Jane E. (Jane Elisabeth)
Description: This bibliometric study examined 19,385 citations in the bibliographies, book reviews, and reading lists of 70 volumes of Adult Education Quarterly, Adult Education, Adult Education Bulletin, Adult Education Journal, and Journal of Adult Education, and 13 volumes of the Handbook of Adult Education in the United States to identify books published before 1960 which have been frequently cited before and after 1960. Through citation analysis, an initial list of 434 titles was reduced to a core list of 64 books cited five times or more during the years between 1934 and 1988. For the purposes of this study, numbers of citations were taken to mean importance of works by indicating usefulness to subsequent authors. Of the 64 books, 55 had received at least one citation before 1960 and 57 had received at least one citation after 1960. While not all 64 of the core works constitute what might be called "classic works," it is suggested that classic works are likely to be found within the listed works.

Polynomial Isomorphisms of Cayley Objects Over a Finite Field

Polynomial Isomorphisms of Cayley Objects Over a Finite Field

Date: December 1989
Creator: Park, Hong Goo
Description: In this dissertation the Bays-Lambossy theorem is generalized to GF(pn). The Bays-Lambossy theorem states that if two Cayley objects each based on GF(p) are isomorphic then they are isomorphic by a multiplier map. We use this characterization to show that under certain conditions two isomorphic Cayley objects over GF(pn) must be isomorphic by a function on GF(pn) of a particular type.

Competencies and In-Service Training of Functional Literacy Teachers in Northeastern Thailand

Competencies and In-Service Training of Functional Literacy Teachers in Northeastern Thailand

Date: December 1989
Creator: Pensri Saeteo
Description: This study was designed to determine (a) the most important knowledge and skills for functional literacy teachers; (b) the most important competencies to be covered in in-service training; (c) whether there were any differences between the perceptions of functional literacy teachers, supervisors, and administrators in terms of needed competencies or areas of training; and (d) whether there were any differences in the perceptions of teachers, supervisors and administrators regarding the need for competencies and for training of functional literacy teachers based upon these variables: age, years of experience in formal and nonformal education, and training in the functional literacy program. It was found that teachers, supervisors, and administrators agreed that most competencies listed in the instrument were important. No significant difference was found in their perceptions of the importance of the competencies. A significant difference was found in the perceptions of the needs for training among these three groups.

Hispanic Representation in the Superintendency: Perceived Competencies and Organizational Outcomes That Benefit School Districts

Hispanic Representation in the Superintendency: Perceived Competencies and Organizational Outcomes That Benefit School Districts

Date: August 2013
Creator: Medina, Fernando
Description: This study assessed 40 factors often cited in literature to determine the extent that Hispanic superintendents perceive them as influential when accessing the superintendency. Eight Hispanic superintendents in Texas participated in this qualitative study, which was based on interviews as well as written responses to a survey. This study found that the factors considered most influential to these superintendents were their ability to communicate, self-perception/self-efficacy, and level of overall preparedness. These findings contrast with previous research indicating that race or ethnicity, mentoring, and career path are most influential. The study also identified factors related to race and ethnicity that most influenced a Hispanic's ability to access the superintendency, albeit to a lesser degree. These factors were the ability to serve as a Hispanic role model to students, ability to increase Hispanic students' academic performance, and the ability to speak a second language. Moreover, through analysis of a large number of survey responses the study examined the extent to which a superintendent's race or ethnicity is significant to addressing the needs of Hispanics. To assure this question a comparative analysis of Hispanics' and non-Hispanics competencies and organizational outcome was conducted. The results indicate that superintendents, in general, regardless of race or ...

Repetition and Difference: Parodic Narration in Kander and Ebb's "The Scottsboro Boys"

Repetition and Difference: Parodic Narration in Kander and Ebb's "The Scottsboro Boys"

Date: August 2013
Creator: Wolski, Kristin Anne
Description: The American musical team John Kander and Fred Ebb created many celebrated works, yet musicologists have carried out little research on those works. This study examines the role of music in the parodic narration of Kander and Ebb's final collaboration, The Scottsboro Boys. Kander and Ebb use minstrelsy to tell the story of the historic Scottsboro Boys trials with actors portraying the Scottsboro Boys as minstrels; at the same time, they employ a number of devices to subvert minstrelsy stereotypes and thereby comment on racism. Drawing on African American literary theory, sociolinguistics, and Bakhtin's dialogism, this study illuminates how Signifyin(g), a rhetorical tradition used to encode messages in some African American communities, is the primary way the actors playing the Scottsboro Boys subvert through minstrelsy. This study not only contributes to the discussion of Signifyin(g) in African American musicals and theatre as a tool of subversion, but also provides an example of non-African American creators—Kander and Ebb—using Signifyin(g) devices. They use these in the music and the book; in particular, Kander and Ebb do some Signifyin(g) on Stephen Foster's plantation melodies.

Metabolic Engineering in Plants to Control Source/sink Relationship and Biomass Distribution

Metabolic Engineering in Plants to Control Source/sink Relationship and Biomass Distribution

Date: August 2013
Creator: Lahiri, Ipsita
Description: Traditional methods like pruning and breeding have historically been used in crop production to divert photoassimilates to harvested organs, but molecular biotechnology is now poised to significantly increase yield by manipulating resource partitioning. It was hypothesized that metabolic engineering in targeted sink tissues can favor resource partitioning to increase harvest. Raffinose Family Oligosaccharides (RFOs) are naturally occurring oligosaccharides that are widespread in plants and are responsible for carbon transport, storage and protection against cold and drought stress. Transgenic plants (GRS47, GRS63) were engineered to generate and transport more RFOs through the phloem than the wild type plants. The transgenic lines produced more RFOs and the RFOs were also detected in their phloem exudates. But the 14CO2 labeling and subsequent thin layer chromatography analysis showed that the RFOs were most likely sequestered in an inactive pool and accumulate over time. Crossing GRS47 and GRS63 lines with MIPS1 plants (that produces more myo-inositol, a substrate in the RFO biosynthetic pathway) did not significantly increase the RFOs in the crossed lines. For future manipulation of RFO degradation in sink organs, the roles of the endogenous α-galactosidases were analyzed. The alkaline α-galactosidases (AtSIP1 and AtSIP2 in Arabidopsis) are most likely responsible for digesting RFOs ...

The Role of Attachment in Perceptions of Interparental Conflict and Behavior Problems in Middle Childhood

The Role of Attachment in Perceptions of Interparental Conflict and Behavior Problems in Middle Childhood

Date: August 2013
Creator: Cusimano, Angela Marie
Description: The current study investigated the association of interparental conflict, parent-child attachment, and children's behavior problems in middle childhood. Although the effects of interparental conflict have been studied extensively, there has been little research done in the developmental period of middle childhood. This study examined the potential mediating role of the attachment relationship between parents and children in a community sample consisting of 86 two-parent families with at least one child between the ages of 8-11. Path modeling procedures indicated that attachment security serves as a mediator between interparental conflict and child behavior problems based on child reports. In particular, child-reported attachment security to the mother significantly mediated the association between children's perceptions of threat from interparental conflict and child-reported internalizing and inattentive/hyperactive symptoms. Child-reported attachment security to the father was not a significant mediator and mediation was not supported in parent-report models. The current findings have implications for families experiencing conflict and speak to the importance of attachment in the parent-child relationship when explaining the association between instances of interparental conflict and child behavioral outcomes. In particular, parents who engage in conflict can prevent the damaging effects of that conflict by making the conflict less overt, explaining to children the ...

Mutual Influences in Romantic Attachment, Religious Coping, and Marital Adjustment

Mutual Influences in Romantic Attachment, Religious Coping, and Marital Adjustment

Date: August 2013
Creator: Pollard, Sara E.
Description: This study examined associations among romantic attachment anxiety and avoidance, positive and negative religious coping, and marital adjustment in a community sample of 81 heterosexual couples. Both spouses completed the Experiences in Close Relationships Scale (ECR), a brief measure of religious coping (Brief RCOPE), the Dyadic Adjustment Scale (DAS), and a demographic questionnaire as part of a larger study. Multilevel modeling (MLM) for the actor-partner interdependence model (APIM) was used. Attachment avoidance was inversely related to positive religious coping. In contrast, attachment anxiety was directly related to negative religious coping. Positive religious coping buffered the relationship between attachment avoidance and marital adjustment. In contrast, attachment anxiety was detrimental to marital adjustment regardless of positive religious coping, and positive religious coping was related to higher marital adjustment only in the context of low attachment anxiety. Surprisingly, the spouse's attachment anxiety was inversely related to the respondent's marital adjustment only when the respondent reported low levels of negative religious coping, whereas in the context of high negative religious coping, the partner's attachment anxiety was related to higher marital adjustment. Results support using attachment theory to conceptualize religious coping and the consideration of both attachment and religious coping constructs in counseling.

Synthesis and Design of Microwave Filters and Duplexers with Single and Dual Band Responses

Synthesis and Design of Microwave Filters and Duplexers with Single and Dual Band Responses

Date: August 2013
Creator: Mandal, Iman K.
Description: In this thesis the general Chebyshev filter synthesis procedure to generate transfer and reflection polynomials and coupling matrices were described. Key concepts such as coupled resonators, non-resonant nodes have been included. This is followed by microwave duplexer synthesis. Next, a technique to design dual band filter has been described including ways to achieve desired return loss and rejection levels at specific bands by manipulating the stopbands and transmission zeros. The concept of dual band filter synthesis has been applied on the synthesis of microwave duplexer to propose a method to synthesize dual band duplexers. Finally a numerical procedure using Cauchy method has been described to estimate the filter and duplexer polynomials from measured responses. The concepts in this thesis can be used to make microwave filters and duplexers more compact, efficient and cost effective.
