Factors Influencing Stakeholder Support of a Bond Referendum in a Rural Kansas School District

The purpose of this study is to examine factors that influence stakeholder support of bond elections targeted for capital improvements in a rural school district in Kansas. The study uses existing research to identify factors that influence school bond referendum success. To better understand the factors identified in the research literature that influence stakeholder support in the focus district, data were gathered from stakeholders within the school district of focus through a perceptual survey and focus group interviews. The availability of research on school bond referendum success and failure is plentiful. However, specific research on factors that influence rural school district stakeholder support for increased taxes to fund capital improvements (new or renovated facilities) is limited, especially rural school districts in Kansas. There is no “one-size-fits-all” strategy in gaining voter support for bond elections. This dissertation seeks to study factors that influence the support of increased taxes to cover capital improvements in one rural school district in Kansas. Results from this study illustrate the importance of consistent and transparent communication over a period of nine to twelve months before asking stakeholders to vote. This allows time for stakeholders to ask questions and understand the importance of a successful bond election. Unanimous support by board of education members was also found to be a critical factor. Community stakeholders should organize and lead the campaign to convince voters to support the bond referendum. Strategies of engagement are included in this study. The results of this research could guide or provide invaluable guidance to other rural school districts in Kansas when investigating voter perceptions towards supporting bond referendums

Deep swarm: Nested particle swarm optimization

A new generation of particle swarm optimization (PSO) has been developed that automatically evolves optimal or near-optimal values for parameters of the PSO algorithm such as population size and neighborhood size, and, if used, parameters of associated neural network(s), such as number of hidden processing elements (PEs). Called Deep Swarm, it is a nested version of PSO, and comprises swarms within a swarm

Stronger but Not Faster : Flipped Classroom Teaching Significantly Improves Resident\u27s Skills but Not Speed

Objective: Flipped classroom teaching is a nontraditional education model where instructional content is delivered outside the classroom. This constructivist approach emphasizes self-direction, active inquiry; the instructor’s role is to foster critical reflection and facilitate the application and understanding of concepts. Our objective was to study the difference in time taken and quality of patch graft angioplasty performed by residents with and without flipped teaching. Methods: The study was set in a skills simulation teaching session overseen by attending surgeons. The intervention consisted of introducing a video outlining the technical aspects of patch graft angioplasty, watched before the session. The first group (2018 postgraduate year [PGY] 1 and 2 residents) was given instructions at the time of the class without a prior educational video or resources (Figs 1 and 2). The second group (2019, 2020 PGY 1 and 2 residents) was asked to watch a 20-minute video on the technical aspects of the procedure before the class. Participants then performed a standardized patch graft closure of a 1 cm arteriotomy using a polytetrafluoroethylene patch. The groups were timed. The quality of the closure was tested by assessing the number of leaks and the quantity of leak of the patch (Fig 3). Bivariate analysis sample t-tests were used for statistical analysis. P value \u3c.05 was considered significant. Pre- and post-session surveys were conducted to assess residents’ experience. Results: Forty-two residents (PGY 1 and 2) were enrolled in the study, 15 in nonintervention group 1 and 27 in intervention group 2, compared with 7 staff vascular surgeons. The mean completion time was 26 minutes (group 1) vs 27 minutes (group 2), P ¼ .6. The staff completion time was 12 minutes, P ¼ .001. The number of major leaks (not needle holes) was 2.0 (group 1) vs 1.6 (group 2), P ¼ .007, none for staff. The total quantity of leak was 42 mL (group 1) vs 15 mL (group 2), P ¼ .0001 (Table I). There was perceived improvement in skill on analyzing pre- and post-session surveys (Table II). Conclusions: A structured educational intervention, watching a video of a procedure before the skills session, did not change the time needed to complete the skill. There was improvement in the technical outcome of the procedure defined by a decrease in the total quantity of leak. Reversed classroom teaching significantly improves resident’s skill, not speed. There was also a perceived improvement in skill by participants. This is a pilot study and further instructional outcomes are being studied

SLC19A1 transports immunoreactive cyclic dinucleotides.

The accumulation of DNA in the cytosol serves as a key immunostimulatory signal associated with infections, cancer and genomic damage1,2. Cytosolic DNA triggers immune responses by activating the cyclic GMP-AMP synthase (cGAS)-stimulator of interferon genes (STING) pathway3. The binding of DNA to cGAS activates its enzymatic activity, leading to the synthesis of a second messenger, cyclic guanosine monophosphate-adenosine monophosphate (2'3'-cGAMP)4-7. This cyclic dinucleotide (CDN) activates STING8, which in turn activates the transcription factors interferon regulatory factor 3 (IRF3) and nuclear factor κ-light-chain-enhancer of activated B cells (NF-κB), promoting the transcription of genes encoding type I interferons and other cytokines and mediators that stimulate a broader immune response. Exogenous 2'3'-cGAMP produced by malignant cells9 and other CDNs, including those produced by bacteria10-12 and synthetic CDNs used in cancer immunotherapy13,14, must traverse the cell membrane to activate STING in target cells. How these charged CDNs pass through the lipid bilayer is unknown. Here we used a genome-wide CRISPR-interference screen to identify the reduced folate carrier SLC19A1, a folate-organic phosphate antiporter, as the major transporter of CDNs. Depleting SLC19A1 in human cells inhibits CDN uptake and functional responses, and overexpressing SLC19A1 increases both uptake and functional responses. In human cell lines and primary cells ex vivo, CDN uptake is inhibited by folates as well as two medications approved for treatment of inflammatory diseases, sulfasalazine and the antifolate methotrexate. The identification of SLC19A1 as the major transporter of CDNs into cells has implications for the immunotherapeutic treatment of cancer13, host responsiveness to CDN-producing pathogenic microorganisms11 and-potentially-for some inflammatory diseases
