Abstract:
Background: Running performance is widely understood interms of the Joyner model (VO2max, %VO2max at ventilatorythreshold (VT), running economy (often measured as cost ofrunning (CR) as VO2 in ml.kg‑1.km‑1).Objective: To test the Joyner model by evaluating a runner inwhom one element of the Joyner model is systematically abnormal.Methods: The case of a two-time Paralympian with cerebral palsy(CP), 2nd place in the Sydney 2000 Paralympic 1500 m (T37) isreported. Incremental and steady state treadmill runs as well assimulated competitions were completed. Incremental and steadystate (50% PPO) cycling with two legs (2L), the non-affected leg(NL), and the affected leg (AL) were also completed.Results: His silver medal (2000 Sydney OG) performance for1500 m was 269 s (4:29) (77.2% of velocity in contemporary ablebodiedworld record (WR). At the time of study, his VO2maxwas 64.2 ml.min‑1.kg‑1. His cost of running (CR) (1% grade) washigher, at 257 vs 228, 211 and 188 ml.kg‑1.km‑1 (for ACSM norms,elite Europeans, elite East Africans). During cycling, his VO2maxwith 2L, NL and AL was 3.74, 3.78 and 3.71 l.min‑1, and his grossefficiency (GE) was 18.4, 12.2 and 9.3%, respectively.Conclusions: In a former elite runner with CP, there is littleevidence of a central oxygen transport limitation. The higherCR (plausibly reflected by the reduced GE of his AL) appears toaccount for much of the difference in performance compared toable-bodied runners. The results provide both insight into thephysiological limitations of runners with CP and support for theJoyner model of competitive running performance.Keywords: biomechanics, athletic training, exercise performance,exercise physiology

Abstract:
The recent death of Amy Joyner, a promising Wilmington, Delaware, high school sophomore demonstrates very clearly the ways in which Black girls are made vulnerable in urban schools. Joyner, an honor roll student, was jumped by a group of girls in the bathroom just before classes began. The alleged cause of the fight was jealousy over a boy. Black girls are bombarded with popular culture messages defining Black femininity along narrow notions of sex appeal, maintaining romantic relationships, and having the ability to fight. Black girls are neither invited in the process of critically examining their popular representation nor supported in thinking through its impact in their own lives. This aspect of the null curriculum, coupled with Black girls’ persistent criminalization, makes schools risky places for Black girls. They are left to navigate a society which misunderstands their gender performance without the support or opportunities they need to develop authentic definitions of self, all the while being held subject to beliefs, policies, and practices which surveil and contain them. Despite the neoliberal assault urban educators face, this article argues that urban educators have an epistemic responsibility to critically examine the denigration of Black womanhood in society, incorporate critical media literacy lessons as one response, and pedagogically support Black girls in the creation of counternarratives as a matter of ethical import. Without such practices, urban schools remain complicit in the physical and civic deaths of Amy Joyner, the girls who attacked her, and all other Black girls caught in the web of risk many urban schools leave unexamined.

The automorphism groups of such codes are determined in most characteristics.

Abstract:
BACKGROUND: The number of ulnar collateral ligament (UCL) injuries in adolescent baseball pitchers has risen over the past 2 decades with the incidence of UCL reconstructions also increasing dramatically over that time period. The Joyner-Andrews magnetic resonance imaging (MRI) classification of UCL tears has previously been described to describe the grade and location of tears, which can aid in surgical decision-making. However, the classification of UCL tears in the at-risk adolescent population has yet to fully investigated. Improving our knowledge of these injuries is crucial to help drive targeted evidence-based treatment strategies. The purpose of this study was to examine the grade and location UCL tears using the Joyner-Andrews MRI classification in a large group of adolescent baseball pitchers. METHODS: We reviewed 225 symptomatic adolescent (aged =19 years) male baseball pitchers with UCL injuries treated by the senior author from 2007-2016. All patients had failed conservative treatment prior to evaluation. Pitchers with a prior history of elbow surgery were excluded. Plain radiographs and MRI arthrograms were evaluated for each patient to categorize the UCL injury and associated pathology. The images were reviewed by a sports medicine-trained orthopedic surgeon. UCL tear grade and location were classified using the Joyner-Andrews classification. RESULTS: The mean age at the time of evaluation was 17.2 ± 1.5 years. 56% of the patients were high school athletes. The majority (59.1%) of UCL tears were high-grade partial tears (Type II). Of those 53.4% were on the humeral side (Type II H). The least common tear types were low-grade partial tears (I) and tears in more than one location (Type IV) in 1.3% and 0.9% of patients, respectively. Plain radiographs revealed 31.4% of patients had abnormal findings; calcifications and olecranon osteophytes were present in 10% and 13% of patients, respectively and more commonly occurred in patients with Type II tears. CONCLUSIONS: The results of this study showed that the majority of adolescent baseball pitchers (59%) sustain high-grade partial tears of the UCL. These findings suggest that effective non-reconstruction options such as platelet-rich plasma and UCL repair with internal brace augmentation could be ideal alternatives to UCL reconstruction for these young patients. The high percentage of radiographic abnormalities in these patients highlights the adaptive changes about the elbow in response to the repetitive stresses experienced by the young elbow during throwing.

Bulletin of the Seismological Society of America 89, no. 5 (October 1, 1999): 1156–70. http://dx.doi.org/10.1785/bssa0890051156.

Full text
Abstract:
Abstract We present SEA99, a revised predictive relation for geometric mean horizontal peak ground acceleration and 5%-damped pseudovelocity response spectrum, appropriate for estimating earthquake ground motions in extensional tectonic regimes, which we demonstrate to have lower ground motions than other tectonic regimes. SEA99 replaces SEA96, a relation originally derived by Spudich et al. (1996, 1997). The data set used to develop SEA99 is larger than that for SEA96, and minor errors in the SEA96 data set have been corrected. In addition, a one-step regression method described by Joyner and Boore (1993, 1994) was used rather than the two-step method of Joyner and Boore (1981). SEA99 has motions that are as much as 20% higher than those of SEA96 at short distances (5-30 km), and SEA99's motions are about 20% lower than SEA96 at longer periods (1.0-2.0 sec) and larger distance (40-100 km). SEA99 dispersions are significantly less than those of SEA96. SEA99 rock motions are on the average 20% lower than motions predicted by Boore et al. (1994) except for short distances at periods around 1.0 sec, where SEA99 motions exceed those predicted by Boore et al. (1994) by as much as 10%. Comparison of ground motions from normal-faulting and strike-slip events in our data set indicates that normal-faulting horizontal ground motions are not significantly different from extensional regime strike-slip ground motions.

Large field plantings are often difficult to label and to plant randomly. A DOS computer program was developed in SAS and BASIC to randomize lists of experimental factors and print sorted paper labels to apply to trees or plants. Tagged trees can be resorted readily by block or row to speed planting. The computer lists are useful for plot verification and subsequent data collection, especially if data are collected and inputted directly to a computer. Copies of the programs are available from W.R. Joyner if a formatted diskette and self-addressed mailer are supplied.

Full text
Abstract:
Attenuation relations using weak ground motion recordings have been determined using data from the New Zealand National Seismograph Network and several temporary seismograph deployments. Models have been developed for earthquake sources in four regions: the Eastern North Island deep and shallow regions and the Central North Island (CNI) deep and shallow regions. Deep events were those with hypocenters below 33 km. Regression coefficients have been determined using the attenuation models of Joyner and Boore (1981) and Molas and Yamazaki (1995). The anelastic attenuation rates in the Eastern North Island expressions are comparable to that of Joyner and Boore (1981), suggesting that weak motion attenuation can be used to estimate variations in strong motion attenuation. However, the absolute level of the strong-motion attenuation curves greatly differs from those of the weak-motion. The anelastic attenuation rate for the shallow CNI is of the order of two to three times that observed for the Eastern North Island. The lowest attenuation rate was found for events within the deep CNI, whose ray paths did not cross the shallow Central North Island region. This is consistent with a low rate of attenuation in the subducting Pacific plate. Azimuthal dependence of PGA is evident within each of the regions. Within the Eastern North Island, the attenuation rate is lowest in the direction of 35-55° from North, which is roughly along the strike of the subducting Pacific plate. A similar azimuthal dependence was also noted within the deep CNI region, while a slightly different minimum direction (5°) was determined for the shallow CNI region.

Abstract:
The authors, Prof. Jonathan Dembo and Prof. Mark Custer have used Unique Page Views generated by Google Analytics to identify and track ten of the least used online manuscript finding aids on the Special Collections Department home page of the J. Y. Joyner Library website at East Carolina University. The authors are unaware of previous attempts to use online access statistics to identify and select archival finding aids for experimental purposes. They are also unaware of any previous attempt to use online access statistics, Unique Page Views (UPV's) or Google Analytics to track and assess the results of finding aid revision experiments. In their experiment, Prof. Custer first generated reports showing Unique Page Views of each online finding aid. Prof. Dembo then revised the finding aids to add information to selected elements, including biographical / historical notes, scope notes, accession information, and inventories. He then tracked the changes in unique page views over more than a year. The authors' findings demonstrate that increasing detail to the finding aids had a dramatic impact on unique page views received. Comparable finding aids selected as a control sample increased at a fraction of the rate of the revised finding aids. Moreover, the authors provide evidence to show that revisions to specific online finding aid elements significantly impacted the relative ranking of the finding aids on the website. Prof. Custer who developed Google Analytics as a research tool at Joyner Library has provided Notes on Technical and Statistical Methods. The authors have also provided five tables illustrating the results and providing web addresses for all the finding aids included in the experiment.

Full text
Abstract:
The Whittier Narrows earthquake of October 1, 1987 generated the largest set of strong-motion records ever obtained from a single earthquake. The California Strong Motion Instrumentation Program (CSMIP) recovered 128 strong-motion records from 101 stations. Of these 101 stations, 63 are ground-response stations and 38 are extensively-instrumented structures. The structures include 27 buildings, eight dams, a suspension bridge, an airport tower, and a power plant. This paper summarizes that data set and highlights records of particular interest. The duration of strong shaking was approximately 3 to 4 seconds at most stations. The maximum peak acceleration values in the CSMIP data set are 0.62 g on the ground and 0.54 g in a structure. The largest acceleration (0.62 g) was recorded at a station near Tarzana, approximately 45 km from the epicenter. Other records of particular interest discussed here include the record from a soft-story building on the Los Angeles State University campus and the records from the Vincent Thomas suspension bridge near Long Beach. Digitization and processing of the accelerograms are underway, and accelerograms from 12 ground-response stations have been digitized as of this writing. The spectra show that the motion at the Tarzana station was dominated by 3 Hz energy. Spectra from other sites are relatively flat and do not show this spectral peak. The attenuation of peak acceleration with distance for this earthquake is compared with the relationship of Joyner and Boore (1981) derived from past earthquakes. On average, the peak acceleration data from this earthquake are higher than would be predicted by the Joyner-Boore model.

Abstract:
Recently at Joyner Library, the main library for West Campus at East Carolina University (ECU), three heads of service completed a project to revise the library’s liaison competencies. The head of collection development, the head of research and instructional services, and the scholarly communication librarian took the competencies from a task-oriented document and turned them into one that allows liaisons to choose what and how they want to learn.

Abstract In this study, the chemical composition, crystal structure, texture properties, and thermal properties of five powdered samples of scoria and pumice volcanic rock from different Harrats were investigated. It was observed that volcanic rocks show variations in chemical compositions, crystal structure, texture, and thermal properties. All samples comprised SiO2, Al2O3, CaO, and Fe2O3 as the major elements and contained both amorphous and crystalline phases. Textural parameters such as surface area and porosity were determined using various calculation models. The surface area of scoria samples was between 0.85 and 1.71 m2 g−1 (Brunauer–Emmett–Teller and Single point model), 0.293–1.028 m2 g−1 (Barrett–Joyner–Halenda model), and 1.02–2.35 m2 g−1 (Langmuir model). While for pumice, the calculated values of the surface area were 1.67 m2 g−1 (Brunauer–Emmett–Teller and Single point model), 0.763 m2 g−1 (Barrett–Joyner–Halenda model), and 2.24 m2 g−1 (Langmuir model). The adsorption-desorption isotherm curves reveal that the scoria and pumice particles under study have mesoporous sizes between 7.89 and 9.81 nm, respectively. The differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA) results of scoria and pumice samples illustrate a thermally stable material at high temperatures. TGA results show a weight gain by about 1.0% has been observed in the scoria samples in the region beyond 600 °C that may indicate a probable oxidation phenomenon with a change in color. While the DSC results of the red scoria and pumice did not show any recrystallization or oxidation, but only showed a small loss of weight in the TGA result. The diversity in molecular composition, texture, and structure of scoria and pumice volcanic rock samples provide for promising natural stable mesoporous materials that can be used in various mesoporous technologies or applications such as solar cells.

Abstract:
We previously developed a technique (R. Kumar, R. Wilders, R. W. Joyner, H. J. Jongsma, E. E. Verheijck, D. A. Golod, A. C. G. van Ginneken, and W. N. Goolsby. Circulation 94: 833-841, 1996) for study of a mathematical model cell with spontaneous activity, viz. a "real-time" simulation of a rabbit sinoatrial node cell (SAN model cell; R. Wilders, H. J. Jongsma, and A. C. van Ginneken. Biophys. J. 60: 1202-1216, 1991) simultaneously being electrically coupled via our "coupling clamp" [H. Sugiura and R. W. Joyner. Am. J. Physiol. 263 (Heart Circ. Physiol. 32): H1591-H1604, 1992] circuit to a real, isolated ventricular myocyte. We now apply this technique to investigate effects of coupling conductance (Gc), cell size, and the modulation of membrane potential by elevated extracellular potassium concentration on the ability of an ectopic focus, represented by the SAN model cell, to successfully drive a ventricular cell. Values of Gc and the relative sizes of the two cells define three possible outcomes: 1) spontaneous pacing of the SAN model cell but not driving of the ventricular cell, 2) cessation of spontaneous pacing, or 3) pacing of the SAN model cell and driving of the ventricular cell. Below a critical size of the SAN model cell only the first two of these outcomes is possible. Above this critical size there is a range of Gc that allows successful operation of the system as an ectopic focus. Elevation of extracellular potassium concentration from 4 to 8 mM increases both the lower bound and upper bound of Gc for this range. Elevation of extracellular potassium concentration, as commonly observed in myocardial ischemia, may have effects on either inhibiting or releasing from inhibition an ectopic focus.

Abstract:
A series of sulfated zirconia was prepared through sol gel method in alcohol medium. Porosity of the catalyst was developed in two different methods, which were immersion of cetyltrimethyl ammonium chloride (CTAC) surfactant as templating agent and Supercritical Fluid Extraction (SFE). The physico-chemical properties of the catalysts were characterized by Thermal Gravimetric-Differential Thermal Analysis (TG-DTA), X-ray Diffraction (XRD), Brunauer-Emmett-Teller (BET) and Barret-Joyner-Halenda (BJH) and gravimetry method for acidity measurement following by the adsorption of organic bases. The characterization results show that different method of immersing CTAC surfactant and SFE affecting physical and chemical properties, i.e. crystalinity, surface area, pore size, pore volume and acidity.

Abstract:
A new synthetic route to ~4 nm grain-sized SnO 2 was proposed which involved a homogeneous precipitation in a deep eutectic solvent (DES) at room temperature. The white SnO 2 precipitate was obtained from SnCl 2 ⋅ 2 H 2 O dissolved DES by injecting slow drop-wise H 4 N 2 ⋅ H 2 O under stirring. The as-prepared nanocrystalline SnO 2 has a Brunauer–Emmett–Teller surface area of 65.12m2/g with an average Barretl–Joyner–Halenda pore diameter of 3.5 nm. As anode for lithium ion batteries, the nanocrystalline SnO 2 electrode delivered an initial charge capacity as high as 1045 mAh/g and its capacity retention is 58% after 30 cycles.

Abstract:
A simple aqueous solution-based block-polymer-assisted method was developed for the synthesis of Mg(OH) 2 nanotubes using inexpensive starting materials ( MgSO 4 and NaOH ) with significant advance of bringing down the average outer diameter to the regime below 10 nm. The synthesized nanotubes are found to possess a relatively high specific surface area up to 64 m2/g, which may suggest their potential value for use in the catalysis field. The Barrett–Joyner–Halenda pore-size distribution plot reveals a bimodal distribution centred at 3.4 and 17.3 nm, which may be from the tunnel cavity and the aggregated pores of Mg(OH) 2 nanotubes, respectively. This method can be widely used to fabricate other inorganic 1D nanostructured materials and easily realized in industrial-scale synthesis.

Abstract:
Abstract There have been several relations proposed in the last few years to describe the amplitudes of ground motion in eastern North America (ENA). These relations differ significantly in their assumptions concerning the amplitude and shape of the spectrum of energy radiated from the earthquake source. In this article, we compare ground motions predicted for these source models against the sparse ENA ground-motion database. The source models evaluated include the two-corner models of Boatwright and Choy (1992), Atkinson (1993a), Haddon (1996), and Joyner (1997a,b), and the one-corner model of Brune [as independently implemented by Frankel et al. (1996) and by Toro et al. (1997)]. The database includes data from ENA mainshocks of M > 4 and historical ENA earthquakes of M > 5.5, for a total of 110 records from 11 events of 4 ≦ M ≦ 7.3, all recorded on rock. We also include 24 available rock records from 4 large earthquakes in other intraplate regions; conclusions are checked to determine whether they are sensitive to the addition of these non-ENA data. The Atkinson source model, as implemented in the ground-motion relations of Atkinson and Boore (1995), is the only model that provides unbiased ground-motion predictions over the entire period band of interest, from 0.1 to 10 sec. The source models of Frankel et al. (1996), Toro et al. (1997), and Joyner (1997a,b) all provide unbiased ground-motion estimates in the period range from 0.1 to 0.5 sec but overestimate motions at periods of 1 to 10 sec. The Haddon (1996) source model overpredicts motions at all periods, by factors of 2 to 10. These conclusions do not change significantly if data from non-ENA intraplate regions are excluded, although the tendency of all models toward overprediction of long-period amplitudes becomes more pronounced. The tendency of most proposed ENA source models to overestimate long-period motions is further confirmed by an evaluation of the relationship between Ms, a measure of the spectrum at 20-sec period, and moment magnitude. A worldwide catalog of shallow continental earthquakes (Triep and Sykes, 1996) is compared to the Ms-M relations implied by each of the source models. The Atkinson source model is consistent with these data, while other proposed ENA models overpredict the average Ms for a given M. The implications of MMI data from historical earthquakes are also addressed, by exploiting the correlation between felt area and high-frequency source spectral level. High-frequency spectral amplitudes, as specified by the Atkinson and Boore (1995), Frankel et al. (1996), Toro et al. (1997), and Joyner (1997a,b) source models, equal or exceed the levels inferred from the felt areas of most of the large ENA events, with the noteable exception of the Saguenay earthquake. By contrast, high-frequency spectral amplitudes specified by the Haddon (1996) source model agree with the felt area of the Saguenay earthquake but overpredict the felt areas of nearly all other large events. In general, models that fit the Saugenay data—be it intensity data, strong-ground-motion data, regional seismographic data, or telescismic data—will not fit the data from the remaining earthquakes. A source model derived from the California database, suitably modified for regional differences in crustal properties, is also evaluated. This model is not significantly different from the Atkinson model for ENA. There is an important practical application of this similarity, which we develop as an engineering tool: Empirical ground-motion relations for California may be modified to predict ENA ground motions from future large earthquakes.
