A refinement of the Shuffle Conjecture with cars of two sizes and t=1/qt=1/q

The original Shuffle Conjecture of Haglund et al. has a symmetric function side and a combinatorial side. The symmetric function side may be simply expressed as $$ where \nabla is the Macdonald polynomial eigen-operator of Bergeron and Garsia and $h_\mu$ is the homogeneous basis indexed by $\mu=(\mu_1,\mu_2,...,\mu_k)$ partitions of n. The combinatorial side q,t-enumerates a family of Parking Functions whose reading word is a shuffle of k successive segments of 1,2,3,...,n of respective lengths $\mu_1,\mu_2,...,\mu_k$. It can be shown that for t=1/q the symmetric function side reduces to a product of q-binomial coefficients and powers of q. This reduction suggests a surprising combinatorial refinement of the general Shuffle Conjecture. Here we prove this refinement for k=2 and t=1/q. The resulting formula gives a q-analogue of the well studied Narayana numbers.Comment: 17 pages, 11 figure

Planning Portfolio: The Process of Strategic Thinking in Advertising

The purpose of account planning is to develop a strategy that guides the creative executions in an advertising campaign. The development of a strategy includes; in-depth secondary research, primary qualitative and quantitative research, discovery of key findings, and the formation of the creative brief. This thesis explores both the creativity and academic rigor necessary to this account planning process. The thesis is in the form of a creative portfolio. Each campaign included in the book (State Farm Insurance, Burton snowboards, and Libby’s pumpkin) have been reduced to the most visually and verbally concise form. Every campaign tells a cohesive narrative starting with research and continuing all the way through creative executions. The portfolio also explores my individual creative thought process as it applies to strategy development and advertising

A Study of the Wellbeing of Siblings of Children with Autism Spectrum Disorders: Sibling Efficacy, Positive and Negative Affect, and Coping Strategies

Autism spectrum disorders (ASD) include pervasive developmental disorders characterised by communication deficits, difficulty with social understanding, and repetitive behaviors. Few studies have compared the efficacy, affect, and coping strategies of siblings of typically developing children with siblings of children with ASD. Typically developing siblings are understood to be at an increased risk of externalising and internalising problems. The current study examined whether siblings of children with ASD differed in levels of efficacy, affect, and coping from siblings of typically developing children. Participants (156) included an Australia-wide sample involving 82 siblings of children with ASD, and 74 siblings of typically developing individuals. Participants completed The Self-Efficacy Scale for Children (assessing social, emotional, and academic efficacy), the Positive and Negative Affect Scales, the Brief COPE Scale, and other scales as part of the larger study. Results showed that ASD siblings reported lower scores on emotional efficacy, social efficacy, and positive affect, and higher negative affect, than did the comparison group siblings. However, no significant differences were found in coping strategies or academic efficacy between the ASD siblings and the typically developing siblings. Consistent with earlier research findings, there are perceived negative effects or risks from being a sibling of an individual with ASD, suggesting support interventions may assist the development of emotional and social efficacy and increased positive affect for these individuals.</jats:p

The Magic of Creative Collaboration: Using LibGuides to Deliver ETD Information

Learning Objectives for a Shared Interest Audience: Identify one or more benefits to a partnership between the Graduate School and the University Libraries to market and deliver ETD processes and procedures online. Recognize how LibGuides can be used to effectively deliver information about writing and submitting electronic theses and dissertations to graduate students. Abstract When the University of Dayton implemented electronic theses and dissertations (ETDs) in 2008, the Graduate School and University Libraries already had a long history of collaboration on format checking and commercial binding of theses and dissertations. The furthering of this partnership was instrumental to the successful implementation of ETDs at UD. As a founding member of the Ohio Library and Information Network (OhioLINK), the Libraries were well-positioned to lead the university’s participation in the OhioLINK ETD Center, a statewide online repository of electronic theses and dissertations. Coincidentally, the University Libraries had recently implemented LibGuides, a hosted Web 2.0 content management and publishing system with pages that were easy to create, customize, update, and access. The Theses and Dissertations Guide was developed incorporating the information a student would need to write and submit a manuscript, including graduation deadlines, graduation checklist, writing guidelines, sample pages, copyright considerations, submission guidelines, FAQs, Graduate School contact information, and links to the OhioLINK ETD Center. The Guide was marketed to the university community as a “one-stop shop” for information about theses and dissertations and quickly became one of the most frequently accessed LibGuides at the University of Dayton. The Graduate School and the Libraries continue to collaborate to educate students, faculty and staff about the ETD process. The Guide is updated frequently based on feedback from the university community

Revolutionizing ETD Operations With Effective Workflows

Learning Objectives: 1. Identify factors to consider when altering existing workflows or setting up new workflows for ETDs. 2. Recognize the value of collaboration between the Graduate School and the Libraries to facilitate efficient workflows for processing, approving, and cataloging ETDs. Summary: This poster will illustrate the evolution of workflows for theses and dissertations at the University of Dayton. When the University of Dayton implemented electronic theses and dissertations (ETDs) in 2008, the Graduate School and the University Libraries already had a long history of collaboration on print format checking and commercial binding of theses and dissertations. The furthering of this partnership was instrumental to the successful implementation of ETDs at UD. The adaptation of existing workflows and the development of new workflows in the Graduate School and the Libraries were required. Mandatory electronic submission was not instituted at the University of Dayton until the Fall of 2011; therefore, the print workflows had to be retained as the electronic workflows were developed. With the advent of electronic submissions, metadata harvested from the OhioLINK ETD Center, a statewide online repository of electronic theses and dissertations, was used as the basis for MARC catalog records. Prior to ETDs, the cataloging of print theses and dissertations was a manual process triggered by the arrival of the Libraries’ commercially-bound copies. Original bibliographic records and name authority records were subsequently contributed to OCLC Worldcat and added to the online catalog. Now system-generated email notifications trigger the online approval process and subsequently, the cataloging process. Other factors influencing workflow include changes in cataloging personnel and metadata processes, changes in the on-campus name verification process, and the development of ETD workflow tracking mechanisms

Validity of GrayMatters: A Self-Administered Computerized Assessment of Alzheimer\u27s Disease

The need for early detection of Alzheimer’s disease has been well established in previous literature. As technology has spread across all professional fields, computerized screening instruments for the early detection of Alzheimer’s disease have begun to draw attention. Research has noted that computerized screeners of dementia should be implemented in primary care physician offices, as the majority of elderly persons see their PCP more frequently than other health professionals. Specifically, self-administered computerized screening instruments that have acceptable psychometric sturdiness are needed for these offices. GrayMatters is a self-administered computerized screening measure that has previously been shown to have acceptable reliability and validity. The aim of this study was to reevaluate the concurrent validity of GrayMatters. Reevaluation was needed in order to compare GrayMatters to the Wechsler Memory Scale-IV, rather than the Wechsler Memory Scale-III as previous research had done, and due to population changes over time. In order to evaluate the concurrent validity of GrayMatters, archival data from 149 female participants and 102 male participants was gathered from the Texas Neuropsychology Clinic. Data sets included participants GrayMatters scores, Wechsler Memory Scale-IV scores, Mini-Mental Status Examination scores, Trailmaking A and B scores, Boston Verbal Fluency Test scores, as well as the participant’s age, gender, race, and level of education. GrayMatters scores were compared to scores from the WMS-IV, MMSE, Trailmaking A and B, and Boston Verbal Fluency Test in order to examine concurrent validity. Results indicate that GrayMatters scores were compatible with scores from all previously mentioned measures. These findings are important because they indicate that GrayMatters can be used as a screening instrument of Alzheimer’s disease that can be used to measure cognitive impairment and guide decisions regarding patient care

Music

Music reference sources continue to evolve, in part because of technological developments and a broadening interest in nonclassical genres, including world music. A few classic works were removed from the list because they are no longer widely available. Others have been subsumed by new print or electronic works. General sources are listed first, followed by sources specific to one or two genres of music. Major categories include blues and jazz, classical, country and gospel, rock and popular, and world music. Works encompassing more than two genres of music are included in the General Sources section. Several select online databases are included, and web links to related sources have been inserted into the narrative, as appropriate
