A pilot of a paper-based assessment tool of design skill is presented. The tool is used to assess the development of skills before and after a first year design experience, and before and after a third year multidisciplinary course in design tools and methodology. The tool is an open-ended survey that may be administered quickly and assessed using a simple rubric. Significant improvements were found over the term of the first year course in the areas of problem definition and testing; improvements were observed in the categories of Conceptual Design, Preliminary Design, and Detailed Design in the third year course. Ideas for future improvement are discussed.

AbstractObjective:A longitudinal pediatric palliative care curriculum was introduced into the pediatric residency program at the University of California, Los Angeles. The present study explores the possible effects of this curriculum on the interns' self-assessed comfort levels regarding caring for children with life-threatening conditions.Methods:A newly created assessment tool was administered to interns in order to rate their comfort regarding pediatric palliative care at the beginning and conclusion of their intern year.Results:Twenty-two of the 29 interns completed this survey. Baseline data indicated 55% of the interns had some experience with taking care of a dying pediatric patient during their medical school training, and 79% indicated that they had taken care of a dying adult. Only 7% of the interns felt adequately prepared to deal with death and dying, but all interns indicated interest in further learning about pediatric palliative care. Comparison of the overall comfort levels of the 22 responding residents before and after the first year of training in 20 different related tasks demonstrated a significant self-assessed improvement of comfort in seven areas. There was no increase in self-reported comfort in communication related to palliative care.Significance of results:Residents indicated increased comfort in some areas of pediatric palliative care after the first year of their training. The underlying cause of this increased comfort is unclear at this time. The overall effect of longitudinal palliative care curriculums on residents' level of comfort in caring for this population deserves further assessment.

AbstractThe aim of this study was to determine the percentage of hatched and fertilized eggs in female Hermann’s tortoises before and after the removal of males after breeding.A breeding group of Testudo hermanni boettgeri with 50 females and 12 males was included in the study. In the first year, all adults were together in the same habitat until reproductive activity was observed. After the end of May, the males and females were separated for the next two active seasons. The number of eggs and number of second clutches decreased gradually. In the first year, 76.0% of females laid eggs; in the second year, 24.0%; and in the third year, only 8.0%. Second clutches were observed in ten females (26.3%) in the first year, while in the next two years, one female had a second clutch. There was a small but significant correlation between the weight of a single tortoise and the number of eggs laid but no significant correlation between the weight of the tortoise and its average egg weight. The weight (15.1-16.8 g), length (33.9-36.1 mm) and width of each egg (27.5-28.0 mm) was measured.During the laying season, the eggs were put into incubators. The incubation length varied from 52 to 70 days. After the end of incubation, eggshell mortality and its causes (19.3-52.5%) were examined. In the first year, the viability rate of the incubated eggs was 80.7%; in the second year, 80.5%; and in the third year, 47.8%. Among the unhatched eggs in the first year, 62.5% were unfertilized, 53.1% were infected, 28.1% were dehydrated and 21.9% were found in various stages of embryonic development.

ABSTRACT By means of chromatographic and spectrophotometric methods progesterone and a substance closely similar to 20β-hydroxy-pregn-4-ene-3-one has been detected in luteal tissue from non-pregnant and pregnant cows. In 21 animals quantitative measurements based on a method giving an average net recovery of 56 per cent showed that in pregnancy the average progesterone content in the corpus luteum reached a maximum in the third to fifth month, with low values before and after this period. For 6 nonpregnant cows, the average value was 20.2 μg/g tissue, which is considerably higher than previous values reported in the literature. The relation between these findings and the bovine dependence on a functional corpus luteum in pregnancy is discussed, and it is pointed out that more information about the metabolism of progesterone in cattle is highly desirable.

The Third

The third chapter traces the beginning of the partnership through the first year of Queen Anne’s reign, as Marlborough persuades Godolphin to return to office as Lord Treasurer and his ministerial partner, with the declared aim of ‘moderation’, that is, holding the balance between the Tories and Whigs on the basis of their support of the war. The role of Queen Anne’s husband Prince George is examined and Marlborough’s and Godolphin’s separate roles are explored, along with the significance of their extensive correspondence. Marlborough is unexpectedly successful in his first campaign, but his determination to obtain a grant from Parliament to support his dukedom jeopardizes Godolphin’s project for war-supply, and their rival Rochester contests control of the Treasury and therefore the war. Marlborough forces Rochester’s resignation and the partnership is confirmed when Marlborough’s only son dies shortly before he leaves for the Continent and he adopts Godolphin’s son as his heir.

Punic Wars

This chapter provides a brief introduction to how the historiographical development of Roman studies, since mid-twentieth century decolonization, has altered our understanding of the developments which took place in North Africa following the destruction of Carthage in 146 bce. The reader is introduced to literary, epigraphic, and archaeological sources of evidence, which have traditionally been used to argue for either cultural change or continuity. After an initial examination of the immediate aftermath of the Third Punic War, Roman land appropriation and taxation, the focus is on sources of evidence usually described as “Punic,” “neo-Punic” or “Late Punic,” covering the spheres of municipal institutions, language use, and religious and funerary rituals. The vibrant multiculturalism and regional diversity of the Mediterranean and especially North Africa, both before and after the Roman conquest, is the dominant theme. This is used to shift emphasis away from grand explanatory paradigms based on essentialist identity categories, and toward a more nuanced picture of the complex and multivariate processes of cultural development and integration.

Objectives (1) Demonstrate true vocal fold (TVF) tracking software (AGATI [Automated Glottic Action Tracking by artificial Intelligence]) as a quantitative assessment of unilateral vocal fold paralysis (UVFP) in a large patient cohort. (2) Correlate patient-reported metrics with AGATI measurements of TVF anterior glottic angles, before and after procedural intervention. Study Design Retrospective cohort study. Setting Academic medical center. Methods AGATI was used to analyze videolaryngoscopy from healthy adults (n = 72) and patients with UVFP (n = 70). Minimum, 3rd percentile, 97th percentile, and maximum anterior glottic angles (AGAs) were computed for each patient. In patients with UVFP, patient-reported outcomes (Voice Handicap Index 10, Dyspnea Index, and Eating Assessment Tool 10) were assessed, before and after procedural intervention (injection or medialization laryngoplasty). A receiver operating characteristic curve for the logistic fit of paralysis vs control group was used to determine AGA cutoff values for defining UVFP. Results Mean (SD) 3rd percentile AGA (in degrees) was 2.67 (3.21) in control and 5.64 (5.42) in patients with UVFP ( P < .001); mean (SD) 97th percentile AGA was 57.08 (11.14) in control and 42.59 (12.37) in patients with UVFP ( P < .001). For patients with UVFP who underwent procedural intervention, the mean 97th percentile AGA decreased by 5 degrees from pre- to postprocedure ( P = .026). The difference between the 97th and 3rd percentile AGA predicted UVFP with 77% sensitivity and 92% specificity ( P < .0001). There was no correlation between AGA measurements and patient-reported outcome scores. Conclusions AGATI demonstrated a difference in AGA measurements between paralysis and control patients. AGATI can predict UVFP with 77% sensitivity and 92% specificity.

Objective To construct deep learning (DL) models to improve the accuracy and efficiency of thyroid disease diagnosis by thyroid scintigraphy. Methods We constructed DL models with AlexNet, VGGNet, and ResNet. The models were trained separately with transfer learning. We measured each model’s performance with six indicators: recall, precision, negative predictive value (NPV), specificity, accuracy, and F1-score. We also compared the diagnostic performances of first- and third-year nuclear medicine (NM) residents with assistance from the best-performing DL-based model. The Kappa coefficient and average classification time of each model were compared with those of two NM residents. Results The recall, precision, NPV, specificity, accuracy, and F1-score of the three models ranged from 73.33% to 97.00%. The Kappa coefficient of all three models was >0.710. All models performed better than the first-year NM resident but not as well as the third-year NM resident in terms of diagnostic ability. However, the ResNet model provided “diagnostic assistance” to the NM residents. The models provided results at speeds 400 to 600 times faster than the NM residents. Conclusion DL-based models perform well in diagnostic assessment by thyroid scintigraphy. These models may serve as tools for NM residents in the diagnosis of Graves’ disease and subacute thyroiditis.
