Why 4-H Members Leave: A Study of Discontinuance Through Both Current 4-H Members and Former Members
No full text4-H members quit. It is part of every 4-H program, and according to the research, it is even part of growing up. If only we knew why they quit, we could possibly do something about it. To date, the reasons youth join 4-H have been more thoroughly researched than the reasons they quit. This study explores why youth choose to discontinue membership in 4-H, and goes a step further, asking current members what they know about the discontinuers, to explore whether current 4-H members can provide information to guide programmatic adjustments to decrease discontinuance.
This study identified a need for better communication and implementation of 4-H enrollment procedures, as 51.9% of discontinuers indicated they were in 4-H, while Texas 4-H enrollment records indicated otherwise. This study also revealed a divergence from the literature. The more active a 4-H member is the more likely they are to re-enroll, according to the literature. In contrast, this study found that 54% of discontinuing 4-H members described themselves as active in their 4-H club, and another 45% describe themselves as active at the county level. The literature also suggests that youth may not be interested in 4-H programs, finding them un-cool or old fashioned, while this study found less than 8% of discontinuing 4-H members described 4-H as un-cool or old fashioned.
This study asked whether any or all of nine different factors influenced the discontinuer to leave, and none was found to be a significant trigger for discontinuance on its own. Most discontinuers agreed with one to four of the factors, implying it takes no more than four factors for a decision to discontinue. There is no one single reason for discontinuance, but it only takes a few reasons to decide to leave.
Responses from current 4-H members about why others leave statistically failed to accurately identify the reasons for discontinuance. This study developed a model of "knowingness" that provides a foundation for understanding how well a current member needs to know a discontinuer in order to accurately describe their reasons for leaving
Murphy Cloggers
No full textThis 1964 photograph shows the Murphy Cloggers from Murphy High School. Founder and director of the Mountain Youth Jamboree, Hubert H. Hayes (1901-1964) auditioned and directed youth to perform in folk dance, music, and folk and ballad singing. The jamboree was held in the Asheville City Auditorium (now known as Thomas Wolfe Auditorium) from 1948 to 1973, and Hayes’ wife, Leona Trantham Hayes (1913-1989) continued to direct the program after his death in 1964. Hubert Hayes was an author, playwright, and alumni of Duke University

High Safety Factor for Action Potential Conduction Along Axons But Not Dendrites of Cultured Hippocampal and Cortical Neurons
No full textMackenzie, Paul J. and Timothy H. Murphy. High safety factor for action potential conduction along axons but not dendrites of cultured hippocampal and cortical neurons. J. Neurophysiol. 80: 2089–2101, 1998. By using a combination of Ca2+imaging and current-clamp recording, we previously reported that action potential (AP) conduction is reliably observed from the soma to axonal terminals in cultured cortical neurons. To extend these studies, we evaluated Ca2+influx evoked by Na+APs as a marker of AP conduction under conditions that are expected to lower the conduction safety factor to explore mechanisms of axonal and dendritic excitability. As expected, reducing the extracellular Na+concentration from 150 to ∼60 mM decreased the amplitude of APs recorded in the soma but surprisingly did not influence axonal conduction, as monitored by measuring Ca2+transients. Furthermore, reliable axonal conduction was observed in dilute (20 nM) tetrodotoxin (TTX), despite a similar reduction in AP amplitude. In contrast, the Ca2+transient measured along dendrites was markedly reduced in low Na+, although still mediated by TTX-sensitive Na+channels. Dendritic action-potential evoked Ca2+transients were also markedly reduced in 20 nM TTX. These data provide further evidence that strongly excitable axons are functionally compartmentalized from weakly excitable dendrites. We conclude that modulation of Na+currents or membrane potential by neurotransmitters or repetitive firing is more likely to influence neuronal firing before AP generation than the propagation of signals to axonal terminals. In contrast, the relatively low safety factor for back-propagating APs in dendrites would suggest a stronger effect of Na+current modulation.</jats:p

Modelling Kepler red giants in eclipsing binaries: calibrating the mixing-length parameter with asteroseismology
No full textStellar models rely on a number of free parameters. High-quality observations of eclipsing binary stars observed by Kepler offer a great opportunity to calibrate model parameters for evolved stars. Our study focuses on six Kepler red giants with the goal of calibrating the mixing-length parameter of convection as well as the asteroseismic surface term in models. We introduce a new method to improve the identification of oscillation modes that exploits theoretical frequencies to guide the mode identification ('peak-bagging') stage of the data analysis. Our results indicate that the convective mixing-length parameter (α) is ≈14 per cent larger for red giants than for the Sun, in agreement with recent results from modelling the APOGEE stars.We found that the asteroseismic surface term (i.e. the frequency offset between the observed and predicted modes) correlates with stellar parameters (Teff, log g) and the mixing-length parameter. This frequency offset generally decreases as giants evolve. The two coefficients a-1 and a3 for the inverse and cubic terms that have been used to describe the surface term correction are found to correlate linearly. The effect of the surface term is also seen in the p-g mixed modes; however, established methods for correcting the effect are not able to properly correct the g-dominated modes in late evolved stars
