Recent Experimental Work

This chapter addresses how linguists’ empirical (syntactic) claims should be tested with non-linguists. Recent experimental work attempts to measure rates of convergence between data presented in journal articles and the results of large surveys. Three follow-up experiments to one such study are presented. It is argued that the original method may underestimate the true rate of convergence because it leaves considerable room for naïve subjects to give ratings that do not reflect their true acceptability judgments of the relevant structures. To understand what can go wrong, the experiments were conducted in two parts. The first part had visually presented sentences rated on a computer, replicating previous work. The second part was an interview where the experimenter asked the participants about the ratings they gave to particular items, in order to determine what interpretation or parse they had assigned, whether they had missed any critical words, and so on.

The Impact

Abstract Background EOE is an increasingly recognized gastrointestinal condition that causes significant morbidity ranging from dietary limitations to food impactions requiring emergency room visits. There are a variety of dietary, pharmacologic and endoscopic treatments available but most are more practically guided by a subspecialist familiar and experienced with the condition. There is a perception among some physicians that follow up is sporadic and may be related at least in part to patient compliance. Aims To assess the true rate of EOE patients follow up rate at Lodon Health Scince Center Methods We used a retrospective cohort of patients diagnosed with EoE between July 2011 and June 2014 who met the traditional diagnostic criteria. As part of a quality improvement initiative, local follow up over the ensuing 5–7 years was tracked. The impact of follow up on subsequent healthcare utilization was analyzed. Results 123 patients with biopsy confirmed EoE were analyzed. Follow up appointments were made for 114/123 (92%) patients. 55/123 (45%) had repeat elective endoscopy booked. Only 10/114 (8.7%) of initial appointments went unattended but 15/55 (27.2%) of the patients offered ongoing follow up failed to attend. There were no complications (ie. perforation or bleeding) attributable to any of the procedures. 5/123 (4%) patients required repeat emergency room endoscopy for food impaction. Two patients required this on multiple occasions. 4/5 patients requiring repeat emergency room endoscopy for food impaction had received some sort of follow up, although 4/5 of these had at least one missed appointment. 2/5 patients having emergency room endoscopy required overnight admission. There were no perforations in the cohort. Conclusions Patients with a confirmed diagnosis of EOE do have a risk of requiring subsequent emergency endoscopy for food impaction although it is not clear that scheduled follow up significantly reduces that risk. Contrary to the perception of some physicians, patients with EoE are very likely to attend their first follow up visit although the attrition rate for subsequent scheduled visits is not insignificant.

The Relationship

Recent experimental work has indicated that species of Archigetes are capable of infecting and maturing in fishes in addition to tubificids.The genus Archigetes is re-defined on the basis of morphological and biological characters, with particular emphasis on recent life history studies. All species capable of neotenic development have been re-united in a single genus.A description of all species of Archigetes together with a key for their identification are included. New synonomies are discussed.The relationship of Archigetes to other genera of the family is briefly considered, and it is concluded that it forms the terminal stage in a series showing the attainment of neotenic development.I wish to thank Professor R. J. Pumphrey in whose Department the work was carried out, and Dr J. C. Chubb for advice and help in the preparation of this manuscript. I am also grateful to Professor K. Berg and Dr R. L. Calentine for the loan of specimens. The work was carried out during the tenure of a Nature Conservancy Research Studentship.

While differencing transformations can eliminate nonstationarity, they typically reduce signal strength and correspondingly reduce rates of convergence in unit root autoregressions. The present paper shows that aggregating moment conditions that are formulated in differences provides an orderly mechanism for preserving information and signal strength in autoregressions with some very desirable properties. In first order autoregression, a partially aggregated estimator based on moment conditions in differences is shown to have a limiting normal distribution that holds uniformly in the autoregressive coefficient ρ, including stationary and unit root cases. The rate of convergence is $\root \of n $ when $\left| \rho \right| < 1$ and the limit distribution is the same as the Gaussian maximum likelihood estimator (MLE), but when ρ = 1 the rate of convergence to the normal distribution is within a slowly varying factor of n. A fully aggregated estimator (FAE) is shown to have the same limit behavior in the stationary case and to have nonstandard limit distributions in unit root and near integrated cases, which reduce both the bias and the variance of the MLE. This result shows that it is possible to improve on the asymptotic behavior of the MLE without using an artificial shrinkage technique or otherwise accelerating convergence at unity at the cost of performance in the neighborhood of unity. Confidence intervals constructed from the FAE using local asymptotic theory around unity also lead to improvements over the MLE.

Let {ξ; t = 1, 2, …} be a stationary normal sequence with zero means, unit variances, and covariances let be independent and standard normal, and write . In this paper we find bounds on which are roughly of the order where ρ is the maximal correlation, ρ =sup {0, r 1 , r 2, …}. It is further shown that, at least for m-dependent sequences, the bounds are of the right order and, in a simple example, the errors are evaluated numerically. Bounds of the same order on the rate of convergence of the point processes of exceedances of one or several levels are obtained using a ‘representation' approach (which seems to be of rather wide applicability). As corollaries we obtain rates of convergence of several functionals of the point processes, including the joint distribution function of the k largest values amongst ξ1, …, ξn.

Collapse Phase

Abstract Numerical prediction of cavitation erosion is a great scientific and technological challenge. In the past, many attempts were made—many successful. One of the issues when a comparison between a simulation and erosion experiments is made, is the great difference in time scale. In this work, we do not attempt to obtain quantitatively accurate predictions of erosion process but concentrate qualitatively on cavitation mechanisms with quantitative prediction of pressure pulses which lead to erosion. This is possible, because of our recent experimental work on simultaneous observation of cavitating flow and cavitation erosion by high speed cameras. In this study, the numerical simulation was used to predict details of the cavitation process during the vapor collapse phase. The fully compressible, cavitating flow simulations were performed to resolve the formation of the pressure waves at cavitation collapse. We tried to visualize the mechanisms and dynamics of vapor structures during collapse phase at the Venturi geometry. The obtained results show that unsteady Reynolds-averaged Navier–Stokes (URANS) simulation of cavitation is capable of reproducing four out of five mechanisms of cavitation erosion, found during experimental work.

Purpose: Following up an Research on Social Work Practice article published a decade ago, this study aimed to examine reference error rates among five, widely circulated social work journals. Methods: A stratified random sample of references was selected from the year 2013 ( N = 500, 100/journal). Each was verified against the original work to detect errors among author name(s), publication year, article title, journal title, volume number, and page numbers. Interrater consistency was 0.88. Results: In the sample, 163 (33%) references contained at least 1 error, producing 258 total errors. Author names held the highest error rate (0.26) and the volume number held the lowest (0.04). The highest error rate was found in Social Service Review (0.48), statistically significantly higher than the remaining journals. Discussion: Reference accuracy in social work journal articles has increased marginally. Substantial reference errors in articles among widely circulated journals may portray an aggregate lack of polished, scholarly writing/editing skills within the profession.

Recent Experimental Work

Recent experimental work on the 1/8 problem by our group is reviewed not only in the La-based cuprate but also in the Bi- and Y-based ones. In the partially Zn-substituted Bi 2 Sr 2 Ca 1-x Y x( Cu 1-y Zn y)2 O 8+δ, we have found anomalous suppression of superconductivity at x=0.30-0.35, where the hole concentration per Cu p~1/8. Moreover, it has been revealed from the μSR measurements that the Cu-spin fluctuations exhibit slowing-down behavior at low temperatures in these samples. These results are suggestive of the stripe correlations of holes and spins tending to be pinned by Zn at p~1/8 in the Bi-nbased cuprate as well as in the La-based cuprate. In Y 1-x Ca x Ba 2 Cu 3 O 7-δ, the 60 K plateau of Tc has been found not to be correlated with the oxygen content but to be interpreted as being due to the suppression of superconductivity at p~1/8. Accordingly, we conclude that the 1/8 problem is common to all high-Tc cuprates with the CuO 2 plane. Moreover, we have found transport and Tc anomalies around x=0.22 in La 2-x Sr x Cu 1-y M y O 4 ( M = Zn , Ga), suggesting a possibility that an order of holes and/or spins is formed or fluctuates in these samples in the overdoped region.
