Narrative of Chain cruise #17, phase I : St. George, Bermuda, to Freetown, Sierra Leone, 19 February - 22 March 1961

The journal of a cruise of R/V CHAIN from Bermuda to Freetown, Sierra Leone during February and March, 1961, is the basis of this report. Location of observations are given. The portion of the Mid- Atlantic Ridge lying along the equator was surveyed from 10° to 19°W, and new information concerning the slope and orientation of rift zones was obtained. A detailed bathymetric survey of the Romanche Trench was made. A continuous temperature-depth profile, from the surface to 100 meters, was made along the ship 's track with a thermistor chain. Surface shear was measured with pitotmeters mounted on the chain (surface water velocity relative to the water velocity at the depth of the pitotmeter), to determine the strength and direction of the equatorial undercurrent.The Office of Naval Research under Contract Nonr-, 2196 (00

Above All Shadows Rides the Sun: Gollum as Hero

Extensive discussion of the complexity of the character of Gollum/Sméagol. He can be seen as a kind of hero, intensely flawed but with incomparable endurance, and essential to the Quest

Adult Attachment Style and Attitudinal Assessment of Preferred Timing of First Marriage

The study assessed the factors contributing to expected ages of marriage in two student populations that are presumed to differ in academic achievement and goals. A primarily goal of this study was to describe the influence that adult attachment style has upon a person\u27s expected age at marriage. A secondary goal was to explore other social and goal-oriented influences on timing of marriage in the two populations. There were no significant differences in attachment style for men and women. The more Avoidantly a person ranked, the later the age at which they expected to get married. University students\u27 ideas about marriage were more influenced by educational goals than the community college sample. There were significant differences between men and women in expected age at marriage and the degree of influence of certain goals. It was found was that the community college students considered themselves to be adults at a younger age than the university group and ideally wanted to start a family at an earlier age

Gifts of the Muse: Reframing the Debate About the Benefits of the Arts

Offers an alternative view of how arts benefits society based on understanding individual, intrinsic benefits as the gateway to more public benefits. Argues that efforts to sustain the supply of the arts should be balanced with a focus on building demand

The Application of Eye-Tracking Technology in the Assessment of Radiology Practices: A Systematic Review

The aim of this review is to provide an in-depth analysis of literature pertaining to the use of eye-tracking equipment in the evaluation of radiological image interpretation by professionals in clinical practice. A systematic search of current literature was conducted through the databases of CINAHL, Medline, ProQuest, PubMed, Scopus, Web of Science and Wiley Online Library. A total of 25 articles were included in the final analysis. The literature gathered referenced four main discussions, which were competency assessment, educational tools, visual search behaviour and assistive aid evaluations. The majority of articles (68%) referenced to the competency assessment of professional groups yet appeared to have conflicting results within the categories of speed and eye-metrics. Significant conclusions could be made pertaining to confidence (100%) and accuracy measurements (56%), which suggested a background of higher experience correlates to a higher rate of accuracy and a higher confidence level. Other findings regarding the main themes focused on eye-tracking as an educational tool, where the literature suggests that such equipment may be useful in improving educational repertoire and interpretation technique. Literature pertaining to the visual search behaviour analysis and the evaluation of assistive aids did not provide strong conclusions due to research limitations. Whilst the use of eye-tracking in the analysis of radiological practices is a promising new venture to quantify the interpretation patterns of professionals, undertaking future research is recommended to solidify conclusions and provide greater insight

The Embodied Statistician

How do infants, children, and adults learn grammatical rules from the mere observation of grammatically structured sequences? We present an embodied hypothesis that (a) people covertly imitate stimuli; (b) imitation tunes the particular neuromuscular systems used in the imitation, facilitating transitions between the states corresponding to the successive grammatical stimuli; and (c) the discrimination between grammatical and ungrammatical stimuli is based on differential ease of imitation of the sequences. We report two experiments consistent with the embodied account of statistical learning. Experiment 1 demonstrates that sequences composed of stimuli imitated with different neuromuscular systems were more difficult to learn compared to sequences imitated within a single neuromuscular system. Experiment 2 provides further evidence by showing that selectively interfering with the tuned neuromuscular system while attempting to discriminate between grammatical and ungrammatical sequences disrupted performance only on sequences imitated by that particular neuromuscular system. Together these results are difficult for theories postulating that grammatical rule learning is based primarily on abstract statistics representing transition probabilities

Quality of care for NSAID users: development of an assessment tool

Objective. Assessments of NSAID use based on authoritative guidelines typically overlook patients’ views and nuances of \ud medical history. Our objective was to develop an assessment tool that incorporates these aspects, and technical items, for quality of care assessments in NSAID users. \ud \ud Methods. Patients newly referred to a university hospital were interviewed by a nurse using an agreed template. A multidisciplinary group of rheumatologists, nurse specialists, primary care physicians and a pharmacist reviewed current guidance and systematic reviews on NSAID use, and a series of interview transcripts. The group agreed, by informal consensus, important determinants of effective and safe NSAID use. Technical aspects of medical care and items that reflected interpersonal care were included in an index for assessing quality of care for individual patients. Interview transcripts of 100 patients were scored by panel members and reliability of scores was tested by calculating weighted percentage agreement and the kappa statistic. \ud \ud Results. Our final index had five domains: medical risk factors; steps taken to reduce risk; knowledge of adverse effects; NSAID dose; and cost efficiency. Each item was scored 0, 1 or 2. Scores were summed, giving a maximum of 10 (low scores indicating low quality). Intra-rater agreement was >90%; kappa was 0.47–0.87 for individual domains and 0.59 for overall score. Inter-rater agreement for overall score was 95%; kappa was 0.25–0.78 for domains and 0.48 for overall score. Patients with especially low scores were identified using the mode of scores for five assessors; obvious clinical concerns were identified, supporting index face validity. \ud \ud Conclusions. A simple index to evaluate quality of care for NSAID users based on a patient interview is described. This may be used by one or more assessors to examine care standards and highlight deficiencies in relation to NSAID use in practice
