Previous experiments have shown that a comparison of two written narratives highlights theirshared relational structure, which in turn facilitates the retrieval of analogous narratives from the past (e.g., Gentner, Loewenstein, Thompson, & Forbus, 2009). However, analogical retrieval occurs across domains that appear more conceptually distant than merely different narratives, and the deepest analogies use matches in higher-order relational structure. The present study investigated whether comparison can facilitate analogical retrieval of higher-order relations across written narratives and abstract symbolic problems. Participants read stories which became retrieval targets after a delay, cued by either analogous stories or letter-strings. In Experiment 1 we replicated Gentner et al. who used narrative retrieval cues, and also found preliminary evidence for retrieval between narrative and symbolic domains. In Experiment 2 we found clear evidence that a comparison of analogous letter-string problems facilitated the retrieval of source stories with analogous higher-order relations. Experiment 3 replicated the retrieval results of Experiment 2 but with a longer delay between encoding and recall, and a greater number of distractor source stories. These experiments offer support for the schema induction account of analogical retrieval (Gentner et al., 2009) and show that the schemas abstracted from comparison of narratives can be transferred to non-semantic symbolic domains.

ABSTRACT When European colonists arrived in the late 19th century, large villages dotted the coastline of the Gulf of Papua (southern Papua New Guinea). These central places sustained long-distance exchange and decade-spanning ceremonial cycles. Besides ethnohistoric records, little is known of the villages’ antiquity, spatiality, or development. Here we combine oral traditional and 14C chronological evidence to investigate the spatial history of two ancestral village sites in Orokolo Bay: Popo and Mirimua Mapoe. A Bayesian model composed of 35 14C assays from seven excavations, alongside the oral traditional accounts, demonstrates that people lived at Popo from 765–575 cal BP until 220–40 cal BP, at which time they moved southwards to Mirimua Mapoe. The village of Popo spanned ca. 34 ha and was composed of various estates, each occupied by a different tribe. Through time, the inhabitants of Popo transformed (e.g., expanded, contracted, and shifted) the village to manage social and ceremonial priorities, long-distance exchange opportunities and changing marine environments. Ours is a crucial case study of how oral traditional ways of understanding the past interrelate with the information generated by Bayesian 14C analyses. We conclude by reflecting on the limitations, strengths, and uncertainties inherent to these forms of chronological knowledge.

Abstract Objective To assess the predictive value of common measures validated to predict falls in other geriatric populations in patients presenting with suspected Normal Pressure Hydrocephalus (NPH). Methods One hundred ninety-five patients over the age of 60 who received the Fall Risk Questionnaire were retrospectively recruited from the CSF Disorders clinic within the departments of Neurosurgery and Neurology. Multiple logistic regression was used to create a model to predict falls for patients with suspected NPH using common measures: Timed Up & Go, Dual Timed Up & Go, 10 Meter Walk, MiniBESTest, 6-Minute Walk, Lower Extremity Function (Mobility), Fall Risk Questionnaire, and Functional Activities Questionnaire. Results The Fall Risk Questionnaire and age were shown to be the best predictors of falls. The model was 95.92% (Positive predictive value: 83.93%) sensitive and 47.92% specific (Negative predictive value: 77.78%). Conclusion Patients presenting with suspected NPH are at an increased fall risk, 75% of the total patients and 89% of patients who responded to a temporary drain of CSF had at least one fall in the past 6 months. The Fall Risk Questionnaire and age were shown to be predictive of falls for patients with suspected NPH. The preliminary evidence indicates measures that have been validated to assess fall risk in other populations may not be valid for patients presenting with suspected NPH.

In the past decade, ecologists have witnessed vast improvements in our ability to collect animal movement data through animal-borne technology, such as through GPS or ARGOS systems. However, more data does not necessarily yield greater knowledge in understanding animal ecology and conservation. In this paper, we provide a review of the major benefits, problems and potential misuses of GPS/Argos technology to animal ecology and conservation. Benefits are obvious, and include the ability to collect fine-scale spatio-temporal location data on many previously impossible to study animals, such as ocean-going fish, migratory songbirds and long-distance migratory mammals. These benefits come with significant problems, however, imposed by frequent collar failures and high cost, which often results in weaker study design, reduced sample sizes and poorer statistical inference. In addition, we see the divorcing of biologists from a field-based understanding of animal ecology to be a growing problem. Despite these difficulties, GPS devices have provided significant benefits, particularly in the conservation and ecology of wide-ranging species. We conclude by offering suggestions for ecologists on which kinds of ecological questions would currently benefit the most from GPS/Argos technology, and where the technology has been potentially misused. Significant conceptual challenges remain, however, including the links between movement and behaviour, and movement and population dynamics.

Aim: The aim of this study was to evaluate the relationship between the results achieved in the Functional Movement Screen test and various aspects of training as well as injury history in long-distance runners. Basic procedures: The study involved 30 long-distance runners aged 20 to 45 years, training regularly from two to seven days a week and covering a total distance from 10 to 100 km. The subjects completed a questionnaire containing queries about training and past injuries. The Functional Movement Screen test was used to assess the quality of movement patterns. Results: The mean total score in the FMS test was 16.03 points. Results within the range from 18 to 21 points were achieved by 6 subjects, 3 of the subjects suffering injuries in the past. Results in the range from 14 to 17 points were obtained by22 subjects, 14 subjects having a history of injury. Ascore below 14 points was reachedby 2 subjects, both of them suffering injuries in the past. Conclusions: The results of this study indicate that a lower FMS score is associated with a greater number of injuries in the past. Warming up before training is a good way to prevent injury, while stretching after training does not seem reduce the incidence of injury.

The article reveals and analyzes the content of physical training of rowers-academics of two schools of higher sportsmanship: Kherson and Dnipro in the preparatory period. The training programs included exercises in gyms with different weights, namely lying down, squats with a barbell; rowing on an ergometer; long distance running. The magnitude of the training load, the intensity of training was determined by coaches depending on the condition of the athlete. Changes in the indicators of physical fitness of these athletes were studied. It is proved that after the training camp in the preparatory period of training rowers-academics the result on the rowing ergometer Concept 2 increased and the growth rate in the national team of Dnipro SHVSM was 1.2%, and in the national team of Kherson SHVSM 0.7%. According to the test, the thrust of the barbell lying - in the national team of the Dnieper SHVSM 11.7%, and in the national team of the Kherson SHVSM 27.8%. A promising area of further work is to study the features of technical training of rowers-academics. The need for targeted training in the training process from the stage of preliminary basic training to higher sports skills requires finding the best options for training planning in each age group and for different periods and stages of the annual cycle. The experience of the past years shows that the process of development of sports results in rowing is organically connected with the improvement of the physical fitness of the rower, but the reserves in this direction are not yet exhausted.
