Inequities in access to quality early care and education: Associations with funding and community context
The purpose of the current study was to examine program- and community-level characteristics related to total points earned by early care and education programs in North Carolina’s Tiered Quality Rating and Improvement System (TQRIS). Multiple statewide data sources, programand community-level characteristics were combined to better understand associations with total points awarded in the TQRIS. The concentration of state and federal funding at the program level, and the socioeconomics of the Q3 communities that programs resided were related to program quality. The current study demonstrated that there are inequities within the system where the highest quality early care and education programs are differentially available based on program funding characteristics, community socioeconomics, and interactions among the program and community variables. Future research and policy implications are discusse
Results of Aortocoronary Bypass Surgery for Angina Pectoris
To determine the relative risks and benefits of coronary bypass surgery for angina pectoris, we examined the results in our first consecutive 360 patients operated upon between May 1970 and December 1975. The age range was 27 to 75 years; there were 309 males and 51 females. The patients were classified clinically as having stable angina in 119 cases (33%), unstable angina in 205 cases (57%) and preinfarction angina in 36 cases (10%). Unstable angina was defined as a definite recent increase in severity or frequency of chest pain, angina at rest or nocturnal angina. Preinfarction angina was defined as a syndrome of prolonged angina, poorly controlled by nitrites, occurring at rest with typical ECG changes of ischemia. Such patients underwent observation in the Coronary Intensive Care Unit followed by emergency arteriography and surgery, usually within 24 hours
How Do Collegiate Sport Clubs Achieve Organizational Effectiveness?
A greater understanding of the organizational processes of sport clubs can inform strategies to improve clubs’ organizational effectiveness. This study examined whether sport club capacity and activities influence the organizational effectiveness of collegiate sport clubs. Sport club members (n = 201) completed a questionnaire, with secondary data collected from the university. Regression analysis found club operations, club fiscal responsibility, frequency of club practice, and frequency of competitions significantly, positively predict organizational effectiveness. Comparatively, club human capital and facility quality significantly, negatively predict organizational effectiveness. These results have implications relating to club training, mentorship, resource allocation, and club activities
Laboratory and Clinical Studies of Cardiac Transplantation
Cardiac transplantation was carried out on four patients at the Medical College of Virginia between May and October of 1968, in an effort to salvage them from the terminal stages of otherwise uncorrectable heart disease. Despite a strikingly good early recovery from operation in each case, three of the patients died of acute homograft rejection in one to three weeks; our second case is living and well, ten months after operation, and is at this writing the world\u27s third longest survivor. The world experience to June of 1969 includes about 130 cardiac transplants. Of the first 100 patients operated on over six months ago, 20 are surviving, and the majority of these have returned to a productive existence, demonstrating the feasibility of complete rehabilitation of at least some terminal patients after cardiac transplantation. The high mortality rate--significantly higher than was anticipated--has resulted from acute and chronic homograft rejection and from the equally difficult problem of infection. Certain lessons have been learned from our own experience and from the world experience with this procedure, and these will be reviewed in an attempt to establish the current status and future potential of cardiac transplantation

Detection of a glitch in the pulsar J1709-4429
We report the detection of a glitch event in the pulsar J17094429 (also
known as B170644) during regular monitoring observations with the Molonglo
Observatory Synthesis Telescope (UTMOST). The glitch was found during timing
operations, in which we regularly observe over 400 pulsars with up to daily
cadence, while commensally searching for Rotating Radio Transients, pulsars,
and FRBs. With a fractional size of ,
the glitch reported here is by far the smallest known for this pulsar,
attesting to the efficacy of glitch searches with high cadence using UTMOST.Comment: 3 pages, 1 figur
The UTMOST pulsar timing programme II:Timing noise across the pulsar population
While pulsars possess exceptional rotational stability, large scale timing
studies have revealed at least two distinct types of irregularities in their
rotation: red timing noise and glitches. Using modern Bayesian techniques, we
investigated the timing noise properties of 300 bright southern-sky radio
pulsars that have been observed over 1.0-4.8 years by the upgraded Molonglo
Observatory Synthesis Telescope (MOST). We reanalysed the spin and spin-down
changes associated with nine previously reported pulsar glitches, report the
discovery of three new glitches and four unusual glitch-like events in the
rotational evolution of PSR J18250935. We develop a refined Bayesian
framework for determining how red noise strength scales with pulsar spin
frequency () and spin-down frequency (), which we apply to a
sample of 280 non-recycled pulsars. With this new method and a simple power-law
scaling relation, we show that red noise strength scales across the
non-recycled pulsar population as , where and . This method can be
easily adapted to utilise more complex, astrophysically motivated red noise
models. Lastly, we highlight our timing of the double neutron star PSR
J07373039, and the rediscovery of a bright radio pulsar originally found
during the first Molonglo pulsar surveys with an incorrectly catalogued
position.Comment: Accepted by MNRAS. 28 pages, 8 figures, 8 table
