    The Tibetan singing bowl is a type of standing bell. Originating from Himalayan fire cults as early as the 5th century BC, they have since been used in religious ceremonies, for shamanic journeying, exorcism, meditation and shakra adjustment. A singing bowl is played by striking or rubbing its rim with a wooden or leather-wrapped mallet. The sides and rim of the bowl then vibrate to produce a rich sound. When the bowl is filled with water, this excitation can cause crispation of the water surface that can be followed by more complicated surface wave patterns and ultimately the creation of droplets. We here demonstrate the means by which the Tibetan singing bowl can levitate droplets. This is a sample arXiv article illustrating the use of fluid dynamics videos.

    We present the results of an experimental investigation of the acoustics and fluid dynamics of Tibetan singing bowls. Their acoustic behavior is rationalized in terms of the related dynamics of standing bells and wine glasses. Striking or rubbing a fluid-filled bowl excites wall vibrations, and concomitant waves at the fluid surface. Acoustic excitation of the bowl's natural vibrational modes allows for a controlled study in which the evolution of the surface waves with increasing forcing amplitude is detailed. Particular attention is given to rationalizing the observed criteria for the onset of edge-induced Faraday waves and droplet generation via surface fracture. Our study indicates that drops may be levitated on the fluid surface, induced to bounce on or skip across the vibrating fluid surface.

  10. The bowling balls

    CERN Bulletin

    2010-01-01

    10 November 1972: CERN’s Bent Stumpe places an order for 12 bowling balls for a total cost of 95 US dollars. Although not evident at first sight, he is buying the heart of some of the first tracking devices to be used in the SPS control room. Today, Bent Stumpe’s device would be called a desktop mouse…   The first order for 4 bowling balls later changed to 12 balls. The bowling balls became the heart of Bent Stumpe's mouse. Almost 40 years ago, the web, Wikipedia and Google did not exist and it was much more difficult to know whether other people in other parts of the world or even in the same laboratory were facing the same problems or developing the same tools. At that time, Bent Stumpe was an electronics engineer, newly recruited to work on developments for the SPS Central Control room. One of the things his supervisor asked him to build as soon as possible was a device to control a pointer on a screen, also called a tracker ball. The heart of the device was the...

  11. Quantifying Cricket Fast Bowling Skill.

    Feros, Simon A; Young, Warren B; O'Brien, Brendan J

    2017-09-27

    To evaluate the current evidence regarding the quantification of cricket fast bowling skill. Studies that assessed fast bowling skill (bowling speed and accuracy) were identified from searches in SPORTDiscus (EBSCO) in June 2017. The reference lists of identified papers were also examined for relevant investigations. Sixteen papers matched the inclusion criteria, and discrepancies in assessment procedures were evident. Differences in: test environment, pitch and cricket ball characteristics, the warm-up prior to test, test familiarisation procedures, permitted run-up lengths, bowling spell length, delivery sequence, test instructions, collection of bowling speed data, collection and reportage of bowling accuracy data were apparent throughout the literature. The reliability and sensitivity of fast bowling skill measures has rarely been reported across the literature. Only one study has attempted to assess the construct validity of their skill measures. There are several discrepancies in how fast bowling skill has been assessed and subsequently quantified in the literature to date. This is a problem, as comparisons between studies are often difficult. Therefore, a strong rationale exists for the creation of match-specific standardised fast bowling assessments that offer greater ecological validity while maintaining acceptable reliability and sensitivity of the skill measures. If prospective research can act on the proposed recommendations from this review, then coaches will be able to make more informed decisions surrounding player selection, talent identification, return to skill following injury, and the efficacy of short- and long-term training interventions for fast bowlers.

    To introduce our first-semester physics students to some basic analytic methods, we integrate a bit of history and a unique timing device into our lab. The story is that the Saxons placed a bowl with a hole in its bottom in water and used the time it took the bowl to submerge to limit orations. (A famous Greek prostitute also used such bowls to allocate her customer's time, an example we do not use in class.) We have our students find a relationship between the diameter of the hole and the time till submergence. Though the original Saxon bowls varied both in hole size and bowl size, for simplicity we vary only the size of the hole.

    Although ethics is an essential component of undergraduate medical education, research suggests that current medical ethics curricula face considerable challenges in improving students' ethical reasoning. This article discusses these challenges and introduces a promising new mode of graduate and professional ethics instruction for overcoming them. We begin by describing common ethics curricula, focusing in particular on established problems with current approaches. Next, we describe a novel method of ethics education and assessment for medical students that we have devised: the Medical Ethics Bowl (MEB). Finally, we suggest the pedagogical advantages of the MEB when compared to other ethics curricula.

    The purpose of this study was to determine whether there were changes in death rates when a local football team participated in the Super Bowl. Los Angeles (LA) played in the Super Bowl twice: on January 20, 1980 (LA Rams vs Pittsburgh Steelers, which LA lost), and on January 22, 1984 (LA Raiders vs Washington Redskins, which LA won). Data from LA County were analyzed for all-cause and circulatory death rates for the Super Bowl and the following 14 days when LA played (Super Bowl-related days) and control days (from January 15 to the end of February for 1980 to 1983 and 1984 to 1988). The Super Bowl-related days during LA's losing 1980 game were associated with higher daily death rates in LA County (per 100,000 population) for all deaths (2.4482 vs 2.0968 for control days, p Super Bowl-related days during the winning 1984 game were associated with a lower rate of all-cause death (2.1870 vs 2.3205 for control days, p = 0.0302). In conclusion, the emotional stress of loss and/or the intensity of a game played by a sports team in a highly publicized rivalry such as the Super Bowl can trigger total and cardiovascular deaths.

  5. Sharing a bowl of tea.

    Soshitsu Sen's keynote speech before a symposium on population and the environment is summarized unofficially by the editorial staff. The instability of human thinking is given as the cause for the present destruction of the environment. In a visit to the His Majesty King of Sweden, Sen remarked that stabilizing human minds can be achieved within the tea ceremony through "serving tea heartily, receiving it with gratitude, and offering it to another." In this way, the spirit of concern for others can be practiced in everyday life and tranquility of mind reached. News broadcasts of starving parents and children as victims of civil war are disheartening. The Japanese people are not suffering such hunger, even though the economy has not been as robust as desired. The analogy is provided in the story by Chuang Chou about King Hun Dun and King Xiu and man's good intentions, which nonetheless destroy the earth. Japan has experienced forest and environmental destruction on the road to economic prosperity and satisfaction of self-interests. The advice on living in accord with nature is to appreciate each season for its own changes. For example, when it is the winter season, the complaint is about the cold and the desire is for spring; but when spring comes, the desire is for the cooler weather of fall. the ordinary way is to appreciate all seasons and is the best way of sustaining a healthy environment. In the garden of the tea hut, humans enter without their worldly title, position, and means; at the water basin, hands and mouth are cleansed, and entrance is made through a small hole into the hut much the same as emerging from the womb. Worldly matters are dispensed with and purity of thought is shared in the sharing of the bowl of green tea, saying "after you" to one another. Christianity and the Way of Tea share the same symbols of purification. The black tea bowl is in harmony with the green tea. Fatigue is relieved when gazing upon the color green; examples are given

    The Nintendo Wii is a gaming console with motion-sensitive controls that is making inroads into health care and rehabilitation. However, there is still limited knowledge on how elderly people perceive the use of such a product. The aim of this study was to examine how the use of the Wii Sports Bowling in an activity group was perceived by elderly people. The data consisted of observations and interviews with participants who used Wii Sports Bowling and was analysed with content analysis. The findings are described in three themes; 'The use of the Wii Sports game', 'Engagement in the game' and 'Social interaction around the activity'. Wii Sports Bowling was described as easier to play compared to real-life bowling and was enjoyable and a social activity. The opportunity to meet the group each week was important for the participants. Playing the game resulted in signs of immersion and a flow-like state. The Wii was perceived to be easy to use, to provide a way to socialize with peers and to give opportunities to participate in activities in a new way. More studies regarding elderly people's experiences and apprehensions regarding new technology such as gaming consoles and virtual reality are needed.

  9. Vinča bowls with protoma

    Directory of Open Access Journals (Sweden)

    Spasić Miloš P.

    2014-01-01

    Full Text Available Bowls with protoma represent one of several tens of types of Vinča vessels made of baked clay which have been published as finds excavated at Vinča sites for more than a century. We are dealing here with bowls of a markedly conical profile, with angled and slightly rounded walls and with a flat or slightly annular bottom. In most cases these bowls are not decorated, with the exception of the rare finds decorated by fluting, engraving and polishing. Their most significant peculiarity is the presence of four or eight protoma on the rim, facing the inside of the vessel. Taking into consideration all stylistic-typological characteristics, it is possible to divide them into two coherent categories of finds. The first consists of bowls with four oppositely placed protoma. Within this group it is possible to single out two subtypes, bowls with all four as anthropomorphic (Pl. I/6, 7; Pl. III/34 or all four as zoomorphic representations (Pl. I/5, 8, 9; Pl. III/33, 36. Bowls with eight protoma have actually got four pairs of oppositely placed representations. It was possible to discern two subtypes based on the objects that were completely preserved. The first subtype includes a bowl from the so-called Vinča ritual set, with two pairs of zoomorphic and two pairs of anthropomorphic protoma, both oppositely placed (Pl. I/3. The second subtype includes a bowl from house 1/2010 from Stubline with four identical, paired, totally stylised and schematised representations, whose identification is impossible (Fig. 1; Pl. I/1. Taking into consideration the metric and technological data, the thesis that seems most possible is that the bowls with protoma served for the consumption of or the storing/displaying of the content during some quite specific activities. Bowls with protoma appear in almost all regions of the central Balkans populated by Vinča culture communities and we do not note them in the areas of the neighbouring Late Neolithic communities.

    Science.gov (United States)

    Bartlett, R M; Stockill, N P; Elliott, B C; Burnett, A F

    1996-10-01

    This review concentrates on synthesizing and analysing the biomechanical research which has been carried out on fast bowling in men's cricket. Specifically, it relates to those elements of the bowling technique which contribute towards a fast ball release, the aerodynamics and technique of swing bowling, and the association between fast bowling and lower back injury. With regard to bowling technique, no firm conclusions are drawn on the relationships between elements of the fast bowling technique and ball release speed. Recommendations for future research in this area include intra-player studies to establish the bowler-specific factors which contribute to fast ball release and features of body segment dynamics. There is general agreement that the phenomenon of differential boundary layer separation is the reason for normal and reverse cricket ball swing. Systematic research to establish the essential aspects of the bowling technique which contribute to successful swing bowling is recommended, along with studies of the behaviour of the ball in games to ascertain the effects of ball asymmetries on ball swing. There is sufficient evidence in the literature to establish a strong link between injury to the lower back and the use of the mixed technique. Recommendations are made for screening and intervention to reduce the use of the mixed technique, and for research into other aspects of injury. Fundamental research to develop biomechanical models of the lower back in fast bowling is strongly recommended.

    2006-01-01

    Whilst numerous investigations have explored the physical demands placed upon competitive sportspeople from a wide array of sports little is known about the physical demands placed on lawn bowlers. The purpose of this study was to ascertain the movement activities of Australian representative singles and pairs players and to determine the frequency and duration of these activities. One match each of two male and two female players (one singles and one pairs player per gender) were videotaped during an international tournament. During playback of the videotaped matches (n = 4), a single observer coded the players’ activities into five distinct categories (waiting, walking forward, walking backward, jogging and bowling) using a computerised video editing system (Gamebreaker™ Digital Video Analysis System). Field calibration of players over 30m for forward motions and 15m for the backward motion was performed to allow for the estimation of total distance covered during the match. Heart rate was monitored during each match. The duration of a match was found to be (mean ± SD) 1hr 28 ± 15mins. The total distance covered during each match was 2093 ± 276m. The mean percentage of match time spent in each motion was: waiting, 61.8 ± 9.3%; walking forward, 22.3 ± 5.6%; walking backward, 2.0 ± 0.4%; jogging, 1.1 ± 0.5%; and bowling, 8.5 ± 4.2%. Average heart rate was found to be 57 ± 7% of age-predicted HRmax with a maximum of 78 ± 9% of age-predicted HRmax. The results of this study suggest that playing lawn bowls at an international level requires light-moderate intensity activity similar to that reported for golf. Key Points The duration of a lawn bowls match played in sets play was 1hr 28 ± 15mins. The majority (65%) of this time was spent in the motion category “waiting”. Players covered more than 2000m during a match with the vast majority (85%) in the form of forward walking. The average heart rate was 107 ± 15 bpm or 57 ± 7% of age-predicted HRmax

    2011-01-01

    The flavour and pleasantness of food and drinks are affected by their colour, their texture or crunch, and even by the shape and weight of the plate or glass. But, can the colour of the bowl also affect the taste of the food it contains? To answer this question we served popcorn in four different coloured bowls, and participants rated sweetness, saltiness, and overall liking. The sweet popcorn, in addition to being sweet, was perceived as saltier when eaten out of a coloured (as compared to a white) bowl, and vice versa for the salty popcorn. These results demonstrate that colour in bowl design can be used to elicit perceptions of sweetness and saltiness in real foods.

    Hesp, Patrick A.; Walker, Ian J.

    2012-01-01

    This paper examines the æolian dynamics of a deep bowl blowout within the foredune of the Greenwich Dunes, on the northeastern shore or Prince Edward Island, Canada. Masts of cup anemometers and sonic anemometers were utilized to measure flow velocities and directions during a strong regional ESE (offshore) wind event. The flow across the blowout immediately separated at the upwind rim crest, and within the blowout was strongly reversed. High, negative vertical flows occurred down the downwind (but seaward) vertical scarp which projected into the separation envelope and topographically forced flow back into the blowout. A pronounced, accelerated jet flow existed near the surface across the blowout basin, and the flow exhibited a complex, anti-clockwise structure with the near-surface flow following the contours around the blowout basin and lower slopes. Significant æolian sediment transport occurred across the whole bowl basin and sediment was delivered by saltation and suspension out the blowout to the east. This study demonstrates that strong offshore winds produce pronounced topographically forced flow steering, separation, reversal, and more complex three-dimensional motions within a bowl blowout, and that such winds within a bowl blowout play a notable role in transporting sediment within and beyond deep topographic hollows in the foredune.

  1. The Tibetan singing bowl : an acoustics and fluid dynamics investigation

    Terwagne, Denis

    2011-01-01

    We present the results of an experimental investigation of the acoustics and fluid dynamics of Tibetan singing bowls. Their acoustic behavior is rationalized in terms of the related dynamics of standing bells and wine glasses. Striking or rubbing a fluid-filled bowl excites wall vibrations, and concomitant waves at the fluid surface. Acoustic excitation of the bowl's natural vibrational modes allows for a controlled study in which the evolution of the surface waves with increasing forcing amplitude is detailed. Particular attention is given to rationalizing the observed criteria for the onset of edge-induced Faraday waves and droplet generation via surface fracture. Our study indicates that drops may be levitated on the fluid surface, induced to bounce on or skip across the vibrating fluid surface.

    Brownish bowl originating from an underwater shipwreck located near Belitung island in the Java Sea, some 600 km south-east from Singapore, has been measured with particle induced X-ray emission. This study was a pilot project for the - now a spin-off company - Recenart research team where one target was to evaluate the authenticity of the different type of art objects. PIXE measurements were done from three different material positions from a single bowl received from a customer. These locations were categorized as a bluish/greenish pigment (under glaze), thick glaze and the body clay. When the obtained data was compared to the other references from different dynasties and kiln sites, the closest match was indeed the Tang dynasty, Tongguan/Ghangsha kiln-site potsherds - from where the bowl in question was also suspected to originate.

    Full Text Available Whilst numerous investigations have explored the physical demands placed upon competitive sportspeople from a wide array of sports little is known about the physical demands placed on lawn bowlers. The purpose of this study was to ascertain the movement activities of Australian representative singles and pairs players and to determine the frequency and duration of these activities. One match each of two male and two female players (one singles and one pairs player per gender were videotaped during an international tournament. During playback of the videotaped matches (n = 4, a single observer coded the players' activities into five distinct categories (waiting, walking forward, walking backward, jogging and bowling using a computerised video editing system (Gamebreaker™ Digital Video Analysis System. Field calibration of players over 30m for forward motions and 15m for the backward motion was performed to allow for the estimation of total distance covered during the match. Heart rate was monitored during each match. The duration of a match was found to be (mean ± SD 1hr 28 ± 15mins. The total distance covered during each match was 2093 ± 276m. The mean percentage of match time spent in each motion was: waiting, 61.8 ± 9.3%; walking forward, 22.3 ± 5.6%; walking backward, 2.0 ± 0.4%; jogging, 1.1 ± 0.5%; and bowling, 8.5 ± 4.2%.

    2013-01-01

    Extraverted children are hypothesized to be most at risk for over-serving and overeating due to environmental cues--such as the size of dinnerware. A within-subject field study of elementary school students found that extraverted children served themselves 33.1% more cereal in larger bowls (16-oz) than in smaller (12-oz) bowls, whereas introverted children were unaffected by bowl size (+5.6%, ns). However, when children were asked by adults how much cereal they wanted to eat, both extraverted and introverted children requested more cereal when given a large versus small bowl. Insofar as extraverted children appear to be more biased by environmental cues, this pilot study suggests different serving styles are recommended for parents and other caregivers. They should serve extraverts, but allow introverts to serve themselves. Still, since the average child still served 23.2% more when serving themselves than when served by an adult, it might be best for caregivers to do the serving whenever possible--especially for extraverted children.

    Full Text Available Teaching Biology concepts such as molecular genetics and inheritance patterns to students in K-12 and college is challenging.  The created Super Bowl Activity uses kinesthetic and visual models and a "hook" to engage students in the material.  Through guided inquiry and modeling, this lesson reviews concepts of DNA, mutations, genotype/phenotype, transcription, translation, homozygous/heterozygous, and inheritance patterns while entertaining the students with a story of a football player with sickle cell trait who couldn’t play in the Super Bowl.  The students create a mutated and normal folded hemoglobin protein model based on amino acid chemical character and use them to simulate Mendelian genetics, inheritance patters, and heterozygous advantage.  This lesson can be used by teachers and professors teaching middle/high school Biology courses as well as Undergraduate Introductory and non-major Biology courses.  This teaching model was created to address content areas where students perform poorly on standardized Biology exams and was presented at a series of professional development workshops for secondary and undergraduate Biology teachers.  One Biology instructor utilized it successfully in her Biology course as a review for end of course exams and felt the students were very engaged in the activity and material.

    Full Text Available The combustion process in the diesel engine should be controlled to avoid both excessive maximum cylinder pressure and an excessive rate of pressure rise, in terms of crank angle. At the same time, the process should be so rapid that substantially all the fuel is burned early in the expansion stroke. In this direction, piston configuration plays a crucial role. Four configurations i.e., flat, inclined, central bowl, and inclined offset bowl piston have been studied. This study is concerned with the CFD analysis has been carried out on two valve four stroke diesel engine to analyze the in-cylinder air motion during suction stroke, pressure and temperature variation inside the cylinder during the compression stroke for various configurations. The engine specifications are considered from the literature. For numerical analysis, Ansys15 CFD software has been used, for meshing polyhedral trimmed cells were adopted. In-cylinder flows were analyzed by solving mass, momentum and energy equation. From this study, it is concluded that analysis has been carried out for each crank angle degree during suction and compression stroke for all the piston configurations, tumble ratio varies mainly with crank angle position. At the end of the compression stroke fuel is injected and the performance of different piston bowls are analyzed.

    This article reconstructs land cover patterns in Depressionera Kansas from historical aerial photos and compares the locations of crop fields to areas of submarginal land identified in modern digital soil survey maps. The analysis argues that New Deal land retirement programs overestimated the degree of bad land use because they lacked the basic science to make comprehensive assessments. The findings demonstrate that the misuse of land unfit for cultivation was relatively rare across the central plains but especially in the Dust Bowl region.

    Full Text Available The excavation works being carried out since 1989 at Dorylaion (Eskişehir/Turkey results in many findings belonging to different civilizations spanning from the First Bronze age to Ottoman period. One of the important groups of these findings is the moldmade bowls, familiarly known as the Megarian bowls from the Hellenistic period (330-30 B.C.. In a frame of an archaeometry project work, these artifacts were characterized with different analytical techniques. Wavelength dispersive X-ray fluorescence (WDXRF and X-ray diffraction (XRD were used to study chemical and mineralogical composition of the bodies. Thermogravimetric-differential thermal analyses (TG-DTA were performed to make the estimation of firing temperature of the sherds. Scanning electron microscopy (SEM and energy dispersive X-ray spectrometry (EDX were performed for the microstructural and microchemical characterization of body and slip layers of the selected potsherds. Based on the analyses results, the bowls should have been prepared from carbonated and siliceous clays and fired at the temperatures from 600 to 1000 °C. They have also iron-rich slip layers with different colors indicating probable adjustment of the redox conditions during firing. In addition, the effect of maximum firing temperature on microstructural characteristics was evaluated.

    The incidence of canine obesity appears to be increasing dramatically and understanding factors impacting the amount of food pet owners provide their dogs may improve weight management. Human research has shown the size of food bowls, plates and utensils can significantly impact the amount of food portioned and consumed. This effect can be attributed to both the Delboeuf optical illusion and the Ebbinghaus-Titchener size-contrast illusion. To investigate the existence of a similar effect with dog owners, 54 dogs and their owners were recruited for a four treatment randomized prospective trial. Owners scooped out a normal kibble-based meal using a small bowl and small scoop, small bowl and large scoop, large bowl and small scoop or a large bowl and large scoop. Each treatment was used once per owner over four visits. Repeated measures anova revealed the mean amount of food portioned using the small bowl and small scoop was significantly less than all other bowl and scoop combinations (150.7 g vs. 171.5 g vs. 172.7 g vs. 184.5 g, p 0.05). Owners were more likely to portion a larger amount of food with a large bowl and large scoop. Results are consistent with human data and emphasize the need for owners to use standard measuring cups. Results also suggest owner compliance during weight loss programs may be improved with smaller bowls and serving scoops. © 2011 Blackwell Verlag GmbH.

    The controlled reaction of Na and Cs, two alkali metals of different ionic sizes and binding abilities, with sumanene (C{sub 21}H{sub 12}) affords a novel type of organometallic sandwich [Cs(C{sub 21}H{sub 11}{sup -}){sub 2}]{sup -}, which crystallized as a solvent-separated ion pair with a [Na(18-crown-6)(THF){sub 2}]{sup +} cation (where THF=tetrahydrofuran). The unprecedented double concave encapsulation of a metal ion by two bowl-shaped sumanenyl anions in [Cs(C{sub 21}H{sub 11}{sup -}){sub 2}]{sup -} was revealed crystallographically.

    Jovanovic Zoran S.

    2011-01-01

    Full Text Available In this paper some results concerning the evolution of 3D fluid flow pattern through all four strokes in combustion chambers with entirely different bowl-in-piston geometry layouts ranging from ”omega” to “simple cylinder” were presented. All combustion chambers i.e. those with „omega“ bowls, with different profiles, and those with „cylinder“ bowls, with different squish area ranging from 44% to 62%, were with flat head, vertical valves and identical elevation of intake and exhaust ports. A bunch of results emerged by dint of multidimensional modeling of nonreactive fluid flow in arbitrary geometry with moving objects and boundaries. The fluid flow pattern during induction and compression in all cases was extremely complicated and entirely three-dimensional. It should be noted that significant differences due to geometry of the bowl were encountered only in the vicinity of TDC. Namely, in the case of “omega” bowl all three types of organized macro flows were observed while in the case of “cylinder” bowl no circumferential velocity was registered at all. On the contrary, in the case of “cylinder” bowl some interesting results concerning reverse tumble and its center of rotation shifting from exhaust valve zone to intake valve zone during induction stroke and vice-verse from intake valve zone to exhaust valve zone during compression were observed while in the case of “omega” bowl no such a displacement was legible. During expansion the fluid flow pattern is fully controlled by piston motion and during exhaust it is mainly one-dimensional, except in the close proximity of exhaust valve. For that reason it is not affected by the geometry of the bowl.

    This article provides a review and synthesis of scholarly knowledge of Depression-era droughts on the North American Great Plains, a time and place known colloquially as the Dust Bowl era or the Dirty Thirties. Recent events, including the 2008 financial crisis, severe droughts in the US corn belt, and the release of a popular documentary film, have spawned a resurgence in public interest in the Dust Bowl. Events of the Dust Bowl era have also proven in recent years to be of considerable interest to scholars researching phenomena related to global environmental change, including atmospheric circulation, drought modeling, land management, institutional behavior, adaptation processes, and human migration. In this review, we draw out common themes in terms of not only what natural and social scientists have learned about the Dust Bowl era itself, but also how insights gained from the study of that period are helping to enhance our understanding of climate-human relations more generally.

    2011-09-01

    Full Text Available Abstract Background Previous studies have reported that the design of the water dispensers can influence the water intake in farm animals. Horses and dairy cows seem to prefer to drink from an open surface whereas sheep and pigs apparently prefer water nipples, probably because of the worse water quality in water bowls. The aim of the present study was to examine the preference of dairy goats for water nipples or water bowls. Methods In each of the two experiments (exp. 1, dry goats, exp. 2 lactating goats, 42 dairy goats were allotted into 6 groups of 7 goats. In period 1, the goats had access to a water nipple. In period 2, they had access to a water bowl and in period 3 (preference test they had access to both a water nipple and a water bowl. Water usage and wastage was recorded and water intake (water usage - water wastage was calculated for each group for the two last days of each period. In experiment 2, water samples from each dispenser were analyzed for heterotrophy germs at 22°C, Escherichia coli and turbidity. Results Water usage was higher from water nipples than from water bowls both in experiment 1 (dry goats and experiment 2 (lactating goats. There was however, no difference in water intake from water nipples and water bowls. In the preference test (period 3, the water intake tended to be higher from the water nipple than from the water bowl both for the dry goats (exp. 1 and lactating goats (exp. 2. Especially for the dry goats, the differences between groups were large. Turbidity and heterotrophy germs were much higher in the samples from the water bowls than from the water nipples. Water wastage from the water bowls was negligible compared to the water nipples. From the water nipples the water wastage was 30% and 23% of water usage for the dry and lactating goats respectively. Conclusions We conclude that type of water dispenser (nipple or bowl was probably of minor importance for water intake in goats, but water bowls had a

  6. PRELIMINARY RESULTS OF BOWL TRAPPING BEES (HYMENOPTERA, APOIDEA IN A SOUTHERN BRAZIL FOREST FRAGMENT

    Directory of Open Access Journals (Sweden)

    Rodrigo B. Gonçalves

    2013-05-01

    Full Text Available In recent years bowl traps have gained attention as a useful method for sampling bees and are now commonly used across the world for this purpose. However, specific questions about the method itself have not yet been tested on different regions of the globe. We present the preliminary results of bowl trapping in a Semidecidual Seasonal forest fragment in southern Brazil, including the test of two different color bowls, two different habitats, and the interaction of these variables in bee species number and composition. We used blue and yellow bowls in the border and in the core trails of the forest fragment. In five sampling days between October to December bowl traps captured 745 specimens of 37 morphospecies, with Halictinae bees being the richest and most abundant group. Non parametrical statistical analyses suggested that different colors of bowl traps influenced bee richness and composition and thus, they should be used together for a more complete sampling. Different trails influenced only the composition, while the interaction with different colors did not have a significant effect. These results, as well as the higher taxonomic composition of the inventoried bees, are similar to other studies reported in the literature.

  8. Evaluation of American Indian Science and Engineering Society Intertribal Middle School Science and Math Bowl Project

    2013-09-25

    The American Indian Science and Engineering Society (AISES) has been funded under a U.S. Department of Energy (DOE) grant (Grant Award No. DE-SC0004058) to host an Intertribal Middle-School Science and Math Bowl (IMSSMB) comprised of teams made up of a majority of American Indian students from Bureau of Indian Education-funded schools and public schools. The intent of the AISES middle school science and math bowl is to increase participation of American Indian students at the DOE-sponsored National Science Bowl. Although national in its recruitment scope, the AISES Intertribal Science and Math Bowl is considered a “regional” science bowl, equivalent to the other 50 regional science bowls which are geographically limited to states. Most regional bowls do not have American Indian student teams competing, hence the AISES bowl is meant to encourage American Indian student teams to increase their science knowledge in order to participate at the national level. The AISES competition brings together teams from various American Indian communities across the nation. Each team is provided with funds for travel to and from the event, as well as for lodging and meals. In 2011 and 2012, there were 10 teams participating; in 2013, the number of teams participating doubled to 20. Each Science and Math Bowl team is comprised of four middle school — grades 6 through 8 — students, one alternate, and a teacher who serves as advisor and coach — although in at least two cases, the coach was not a teacher, but was the Indian Education Coordinator. Each team member must have at least a 3.0 GPA. Furthermore, the majority of students in each team must be comprised of American Indian, Alaska Native or Native Hawaiian students.

    Highlights: • Bronze bowl from Iran belonging to a private collection. • Style and manufacturing consistent with the Achaemenid art (I century B.C.). • Modified Type I patinas. • Apparently continuous tenorite layer at the metal surface on the internal bowl side. • Fragmentation attributed to a severe intergranular attack. - Abstract: A bronze bowl belonging to a private collection, stylistically consistent with the Achaemenid art was investigated to determine the cause of the artwork local fragmentation. The corrosion products were characterised by energy dispersive X-ray fluorescence spectrometry (EDXRF), Raman spectroscopy and scanning electron microscopy (SEM) equipped with energy dispersive spectroscopy (EDS). The last technique was also used to determine the chemical composition of the alloy. The metallographic analysis showed that the bowl was obtained from a monophasic bronze alloy, containing about 11% tin and other elements in traces. The presence of an inhomogeneous microstructure with both thermal twin bands and slip lines was consistent with multiple hammering steps followed by partial annealing treatments. On the bowl a very limited chloride contamination was observed and chlorides were never detected in proximity to the metal. These findings and the morphological/compositional characteristics of the patinas permitted to classify that on the internal side of the bowl as a modified Type I morphology, while the patina on the external side of the bowl was less compact, so that it was judged borderline between a “noble” patina and a disfiguring one. On this side, a significant intergranular attack was found, reputed responsible for the fragmentation occurred.

    2016-01-01

    The objective of the study was to evaluate two types of cricket bowling techniques by comparing the lumbar spinal loading using a musculoskeletal modelling approach. Three-dimensional kinematic data were recorded by a Vicon motion capture system under two cricket bowling conditions: (1) participants bowled at their absolute maximal speeds (max condition), and (2) participants bowled at their absolute maximal speeds while simultaneously forcing their navel down towards their thighs starting just prior to ball release (max-trunk condition). A three-dimensional musculoskeletal model comprised of the pelvis, sacrum, lumbar vertebrae and torso segments, which enabled the motion of the individual lumbar vertebrae in the sagittal, frontal and coronal planes to be actuated by 210 muscle-tendon units, was used to simulate spinal loading based on the recorded kinematic data. The maximal lumbar spine compressive force is 4.89 ± 0.88BW for the max condition and 4.58 ± 0.54BW for the max-trunk condition. Results showed that there was no significant difference between the two techniques in trunk moments and lumbar spine forces. This indicates that the max-trunk technique may not increase lower back injury risks. The method proposed in this study could be served as a tool to evaluate lower back injury risks for cricket bowling as well as other throwing activities.

    This paper describes a model for homeland security, community readiness, and medical response that was applied during an operational exercise around Super Bowl XXXVII. In addition, it describes the products provided by private companies involved in the exercise and how they would have contributed to a medical disaster had one occurred. The purpose of Shadow Bowl was to demonstrate community readiness and medical response to a mass casualty event. The goals of the project were to: (1) provide enhanced public safety using an advanced communication network and sensor grid; (2) develop mass casualty surge capabilities through medical reach-back; and (3) build a collaboration model between civilian, military, public, and private partners. The results of the Shadow Bowl Exercise accentuated the value of new telehealth and disaster medicine tools in treating large numbers of patients when infrastructure overload occurs.

    The depletion of fossil fuels and hike in crude oil prices were some of the main reasons to explore new alternatives from renewable source of energy. This work presents the impact of various bowl geometries on diesel engine with diesel and biodiesel samples. Three non-edible oils were selected, namely pumpkin seed oil, orange oil and neem oil. These oils were converted into respective biodiesel using transesterification process in the presence of catalyst and alcohol. After transesterification process, the oils were termed as pumpkin seed oil methyl ester (PSOME), orange oil methyl ester (OME) and neem oil methyl ester (NOME), respectively. The engine used for experimentation was a single-cylinder four-stroke water-cooled direct-injection diesel engine and loads were applied to the engine using eddy current dynamometer. Two bowl geometries were developed, namely toroidal combustion chamber (TCC) and trapezoidal combustion chamber (TRCC). Also, the engine was inbuilt with hemispherical combustion chamber (HCC). The base line readings were recorded using neat diesel fuel with HCC for various loads. Followed by 20% of biodiesel mixed with 80% neat diesel for all prepared methyl esters and termed as B1 (20% PSOME with 80% diesel), B2 (20% OME with 80% diesel) and B3 (20% NOME with 80% diesel). All fuel samples were tested in HCC, TCC and TRCC bowl geometries under standard injection timing and with compression ratio of 18. Increased brake thermal efficiency and reduced brake specific fuel consumption were observed with diesel in TCC geometry. Also, higher heat release and cylinder pressures with lower ignition delay were recorded with TCC bowl geometry. TCC bowl geometry showed lower CO, HC and smoke emissions with B2 fuel sample than diesel and other biodiesel samples. But, higher NOx emission was observed in HCC and TCC than that in TRCC bowl geometry. Graphical abstract ᅟ.

  1. Pretend play.

    Weisberg, Deena Skolnick

    2015-01-01

    Pretend play is a form of playful behavior that involves nonliteral action. Although on the surface this activity appears to be merely for fun, recent research has discovered that children's pretend play has connections to important cognitive and social skills, such as symbolic thinking, theory of mind, and counterfactual reasoning. The current article first defines pretend play and then reviews the arguments and evidence for these three connections. Pretend play has a nonliteral correspondence to reality, hence pretending may provide children with practice with navigating symbolic relationships, which may strengthen their language skills. Pretend play and theory of mind reasoning share a focus on others' mental states in order to correctly interpret their behavior, hence pretending and theory of mind may be mutually supportive in development. Pretend play and counterfactual reasoning both involve representing nonreal states of affairs, hence pretending may facilitate children's counterfactual abilities. These connections make pretend play an important phenomenon in cognitive science: Studying children's pretend play can provide insight into these other abilities and their developmental trajectories, and thereby into human cognitive architecture and its development.

  18. The Importance of a Conchal Bowl Element in the Fabrication of a Three-Dimensional Framework in Total Auricular Reconstruction

    2013-05-01

    Full Text Available BackgroundTo construct a sophisticated three-dimensional framework, numerous modifications have been reported in the literature. However, most surgeons have paid little attention to the anatomical configuration of the concha and more to its deepness and hollowness, leading to unsatisfactory outcomes.MethodsFor a configuration of the concha that is definitely anatomical, the author further developed and employed the conchal bowl element, which has been used by several surgeons although the results have not been published elsewhere. The author constructed the conchal bowl element in one of three patterns according to the amount of available cartilages: one block, two-pieces, or a cymba bowl element only. A total of 20 patients underwent auricular reconstruction using a costal cartilage framework between 2009 and 2012. The 8 earliest reconstructions were performed without a conchal bowl element and the latter 12 with a conchal bowl element. The patients were followed up for more than 1 year. The aesthetic results were scored by evaluating characteristics involving the stability of the crus helicis, the conchal definition, and the smoothness of the helical curve.ResultsThe ears reconstructed early without a conchal bowl element showed a shallow and one or two incompletely separated concha with an obliterated cymba conchal space. They also did not have a realistic or smooth curve of the helix because of an unstable crus helicis. However, ears reconstructed later with the concha bowl element showed a definite crus helicis, deep cymba conchal space, and smooth helical curve.ConclusionsThe construction of the conchal bowl element is simple, not time-consuming procedure. It is suggested that the conchal bowl element must be constructed and attached to the main framework for natural configuration of the reconstructed ear.

    2016-04-01

    Full Text Available This study attempts to find if better performance in power play leads a team to victory in a Twenty20 match. Based on the methodology devised to do so, the study tries to measure the performance of both the teams during power play overs in terms of batting and bowling. The developed measure is called ‘Prod’ which is a product of the difference of batting and bowling performance of the teams during power play overs. The team with better performance in both the skills during power play is expected to win the match. But it would be difficult to predict the outcome of a match if the performance of a team is better in bowling and worse in batting and vice-versa. A total of 261 matches from different seasons of Indian Premier League (IPL are considered for the study. The outcomes of 220 matches are predicted based on the performance of two teams in power play out of which 153 of them were correctly predicted. Remaining 41 matches could not be predicted as it is not clear which team performed better during power play. Thus, out of the matches where the dominance of a team was clear in the power play, 70 percent cases that team ultimately won the match in Twenty20 cricket.

    The purpose of this study was to discover the contributions of individual upper body segmental rotations to ball release speed for cricket bowling and determine whether attempting to forcefully flex the lower trunk leads to an increase in ball release speed and bowling accuracy. Three dimensional kinematic data of eight male fast bowlers were recorded by a Vicon motion capture system under three cricket bowling conditions: (1) participants bowled at their stock delivery speeds (sub-max condition), (2) participants bowled at their absolute maximal speeds (max condition), and (3) participants bowled at their absolute maximal speeds but forced to flex the lower trunk (max-trunk condition). The accuracy of each delivery was also measured. The results showed that the average ball release speeds for the max-trunk condition were faster than the other two conditions. A general pattern of proximal to distal sequencing was observed for all three conditions. There was a slight decrement in accuracy seen in the max-trunk condition with respect to the other two conditions. For all three conditions, the upper arm rotation made the largest contribution, followed in turn by torso and thorax rotation, pelvis rotation, linear velocity of pelvis, and forearm and hand rotation.

    Studies have estimated the relationship between psychological stress and birth weight by exploiting natural disasters and terrorist attacks, both of which could affect fetal health through other channels. Using data from the National Vital Statistics System for the period 1969-2004, we estimate the effect of prenatal exposure to the Super Bowl on low birth weight. Although major sporting events elicit intense emotions, they do not threaten viewers with direct physical harm or limit access to ...

    Modeling the mononuclear site of copper enzymes is important for a better understanding of the factors controlling the reactivity of the metal center. A major difficulty stems from the difficult control of the nuclearity while maintaining free sites open to coordination of exogenous ligands. A supramolecular approach consists in associating a hydrophobic cavity to a tripodal ligand that will define the coordination spheres as well as access to the metal ion. Here, we describe the synthesis of a bowl Cu(II) complex based on the resorcinarene scaffold. This study supplements a previous work on Cu(I) coordination. It provides a complete picture of the cavity-copper system in its two oxidation states. The first XRD structure of such a bowl complex was obtained, evidencing a 5-coordinate Cu(II) ion with the three imidazole donors bound to the metal (two in the base of the pyramid, one in the apical position) and with an acetate anion, completing the base of the pyramid, and deeply included in the bowl. Solution studies conducted by EPR and UV-vis absorption spectroscopies as well as cyclic voltammetry highlighted interaction with coordinating solvents, various carboxylates that can sit either in the endo or in the exo position depending on their size as well as possible stabilization of hydroxo species in a mononuclear state. A comparison of the binding and redox properties of the bowl complex with funnel complexes based on the calix[6]arene core further highlights the importance of supramolecular features defining the first, second, and third coordination sphere for control of the metal ion.

    Two new tetranuclear cationic metalla-bowls 4 and 5 were self-assembled from a bis-pyridine amide ligand (H(2)L) (1) and arene-ruthenium acceptors, [(Ru(2)(μ-η(4)-C(2)O(4))(η(6)-p-cymene)(2)](O(3)SCF(3))(2) (2) and [Ru(2)(dhnd)(η(6)-p-cymene)(2)](O(3)SCF(3))(2) (dhnd = 6,11-dihydroxy-5,12-naphthacenedionato) (3), respectively. The metalla-bowls were characterized by multinuclear NMR, ESI-MS, UV-Vis spectroscopy, and single crystal X-ray diffraction study of 4. The crystal structure of 4 reveals unambiguous proof for the molecular shape of the metalla-bowl and the encapsulation of one triflate anion in the cavity through hydrogen bonding. The metalla-bowl 5 has been evaluated for anion binding studies by use of amide ligand as a hydrogen bond donor and arene-Ru acceptor as a signalling unit. UV-Vis titration studies showed that 5 selectively binds with multi-carboxylate anions such as oxalate, tartrate and citrate in a 1 : 1 fashion with high binding constants of 4.0-5.5 × 10(4) M(-1). Furthermore, the addition of multi-carboxylate anions into a solution of 5 gave rise to a large enhancement of fluorescence intensity attributable to the blocking of a photo-induced electron transfer process from the arene-ruthenium moiety to the amidic donor in 5. However, the fluorescence intensity almost remains unchanged upon addition of other anions including F(-), Cl(-), PF(6)(-), MeCOO(-), NO(3)(-) and PhCOO(-), as identically seen in the UV-Vis titration experiments, pointing to the high selectivity of 5 for the sensing of multi-carboxylate anions.

    High-efficient, plasmon-enhanced nonlinear phenomena based on hybrid nanostructures, which combine nonlinear dielectrics with plasmonic metals, are of fundamental importance for various applications ranging from all-optical switching to imaging or bio-sensing. However, the high loss of the excitation energy in nanostructures and the poor spatial overlap between the plasmon enhancement and the bulk of nonlinear materials largely limit the operation of plasmon-enhanced nonlinear effects, resulting in low nonlinear conversion efficiency. Here, we design and fabricate a ZnO-covered, 2D silver-bowl array, which can serve as an efficient platform for plasmon-enhanced second-harmonic generation (PESHG). Validated by experiments and simulations, we demonstrate that the high spatial overlap between the near-field enhancement and the ZnO film plays the key role for this nanostructure-based PESHG process. The enhancement mainly originates from the fundamental wavelength-derived plasmon resonance, providing an enhancement factor of approximately 33 times. These results achieved pave the way for future applications, which require localized light sources at nanoscale.

    Psychological and psychomotor skills associated with prowess at ten-pin bowling were identified through factor analysis of ratings provided by 172 bowlers (87 males, 85 females) across a range of current averages (a measure based on recent performance in competition). Skilled bowlers (current average of 170 pins or more) differed significantly from less skilled bowlers (current average of less than 135 pins) on seven component skills. They demonstrated greater mental toughness, a higher degree of planning and evaluation, greater consistency, more interest in improvement, less use of luck attributions, more confidence in equipment and technique, and greater competitiveness. Since men and women of the same overall standard (current average) have similar component skill profiles, ten-pin bowling is a gender-neutral sport. Older bowlers (45-79 years) matched by current average with younger bowlers (16-30 years) differed significantly on only one component, level of commitment. We discuss several contexts for use of the three self-report assessment scales (measures of psychological skills, psychomotor skills and involvement in bowling) developed in this study.

    Full Text Available Our society is drenched in the catastrophe; where the growth of financial crisis, environmental cataclysm and militarization represents its gaudiest and mortifying phenomena. Humans struggle with depression, sense of impotence, anguish towards a future considered a threat.  A possibility to keep us alive can be represented by the enhancement of our ability in ‘playing Possum’, an exercise of desisting and renitence: to firmly say ‘no’. To say no to a world that proposes just one way of being and living free, that imposes as the only unavoidable possible destiny.

    Mrs. Zahia Marzouk, vice-president of the Alexandria Family Planning Association and a living legend of Egyptian family planning, does not believe in talking about problems. She is far too busy learning from people and teaching them. Her latest brainstorm is a set of playing cards designed to help girls and women to read and learn about family planning at the same time. The 5 packs of cards, representing familiar words and sounds, and each with a family planning joker, took Mrs. Marzouk 6 months to design and paint by hand. They have now been printed, packed into packets provided by UNICEF, and distributed to some 2000 literacy groups in factories and family planning clinics. Each woman who succeeds in learning to read is encouraged to teach 4 others. They then go to the family planning clinic to be examined and gain a certificate. For the teacher who has made them proficient there is a special prize. Girls at El Brinth village outside Alexandria are pictured playing cards at the family planning center where they are learning various skills including how to read.

    2013-05-01

    Full Text Available Background  To construct a sophisticated three-dimensionalframework, numerousmodifications have been reported in the literature. However, mostsurgeons have paid little attentionto the anatomical configuration of the concha and more to its deepness and hollowness,leading to unsatisfactory outcomes.Methods  For a configuration ofthe concha thatis definitely anatomical,the authorfurtherdeveloped and employed the conchal bowl element,which has been used by severalsurgeonsalthough the results have not been published elsewhere. The author constructed the conchalbowl element in one of three patterns according to the amount of available cartilages: oneblock,two-pieces, or a cymba bowl element only. A total of 20 patients underwent auricularreconstruction using a costal cartilage framework between 2009 and 2012. The 8 earliestreconstructionswere performedwithout a conchal bowl element and the latter 12with a conchalbowl element. The patientswere followed up for more than 1 year. The aesthetic resultswerescored by evaluating characteristicsinvolving the stability ofthe crus helicis,the conchal definition, and the smoothness ofthe helical curve.Results  The earsreconstructed earlywithout a conchal bowl elementshowed a shallowandone or two incompletely separated concha with an obliterated cymba conchal space. Theyalso did not have a realistic orsmooth curve ofthe helix because of an unstable crus helicis.However, earsreconstructed laterwith the concha bowl elementshowed a definite crus helicis,deep cymba conchalspace, and smooth helical curve.Conclusions  The construction of the conchal bowl element is simple, not time-consumingprocedure. It is suggested that the conchal bowl element must be constructed and attachedto themain framework for natural configuration ofthe reconstructed ear.

  19. "Hot hand" on strike: bowling data indicates correlation to recent past results, not causality.

    Directory of Open Access Journals (Sweden)

    Gur Yaari

    Full Text Available Recently, the "hot hand" phenomenon regained interest due to the availability and accessibility of large scale data sets from the world of sports. In support of common wisdom and in contrast to the original conclusions of the seminal paper about this phenomenon by Gilovich, Vallone and Tversky in 1985, solid evidences were supplied in favor of the existence of this phenomenon in different kinds of data. This came after almost three decades of ongoing debates whether the "hot hand" phenomenon in sport is real or just a mis-perception of human subjects of completely random patterns present in reality. However, although this phenomenon was shown to exist in different sports data including basketball free throws and bowling strike rates, a somehow deeper question remained unanswered: are these non random patterns results of causal, short term, feedback mechanisms or simply time fluctuations of athletes performance. In this paper, we analyze large amounts of data from the Professional Bowling Association(PBA. We studied the results of the top 100 players in terms of the number of available records (summed into more than 450,000 frames. By using permutation approach and dividing the analysis into different aggregation levels we were able to supply evidence for the existence of the "hot hand" phenomenon in the data, in agreement with previous studies. Moreover, by using this approach, we were able to demonstrate that there are, indeed, significant fluctuations from game to game for the same player but there is no clustering of successes (strikes and failures (non strikes within each game. Thus we were lead to the conclusion that bowling results show correlation to recent past results but they are not influenced by them in a causal manner.

    To assess workload-related risk factors for injuries to particular tissue types in cricket fast bowlers. 235 fast bowlers who bowled in 14600 player innings over a period of 15 years were followed in a prospective cohort risk factor study to compare overs bowled in each match (including preceding workload patterns) and injury risk in the 3-4 weeks subsequent to the match. Injuries were categorised according to the affected tissue type as either: bone stress, tendon injuries, muscle strain or joint injuries. Workload risk factors were examined using binomial logistic regression multivariate analysis, with a forward stepwise procedure requiring a significance of injuries, but high medium term (3-month workload) was protective. For bone stress injuries, high medium term workload and low career workload were risk factors. For joint injuries, high previous season and career workload were risk factors. There was little relationship between muscle injury and workload although high previous season workload was slightly protective. The level of injury risk for some tissue types varies in response to preceding fast bowling workload, with tendon injuries most affected by workload patterns. Workload planning may need to be individualised, depending on individual susceptibility to various injury types. This study supports the theory that tendons are at lowest risk with consistent workloads and susceptible to injury with sudden upgrades in workload. Gradual upgrades are recommended, particularly at the start of a bowler's career to reduce the risk of bone stress injury. Published by the BMJ Publishing Group Limited.

  1. The case for a southeastern Australian Dust Bowl, 1895-1945

    Australia has an anecdotal history of severe wind erosion and dust storm activity, but there has been no lasting public perception of periods of extreme dust storm activity in this country, such as that developed in the USA following the Dust Bowl of the 1930s. Newspaper accounts of droughts and dust storms in southeastern (SE) Australia between 1895 and 1945 suggest that, at various times, the scale of these events was comparable to those experienced in the USA Dust Bowl. During this 50-year period, average annual rainfall values in this region were substantially below long-term averages, air temperatures were distinctly warmer, marginal lands were actively cropped and grazed, and rabbits were a burgeoning grazing pest. From the beginning of the Federation Drought of 1895-1902, dust storm activity increased markedly, with the downwind coastal cities of Sydney and Melbourne experiencing dust hazes, dust storms and falls of red rain relatively regularly. Between 1935 and 1945, Sydney and Melbourne received ten and nine long-distance dust events, respectively, with the years of 1938 and 1944/45 being the most intensely dusty. Entire topsoil horizons were blown away, sand drift was extreme, and crops and sheep flocks were destroyed. Although these periods of extreme dust storm activity were not as sustained as those experienced in the USA in the mid-1930s, there is a strong case to support the contention that SE Australia experienced its own extended, somewhat episodic version of a Dust Bowl, with a similar combination of causal factors and landscape effects.

    Recently, it has been demonstrated that the combination of periodic dielectric structures with metallic structures provides an efficient means to yield a synergetic optical response or functionality in the resultant hybrid plasmonic-photonic systems. In this work, a new hybrid plasmonic-photonic structure of 2D-ordered dielectric sub-micron bowls on a flat gold surface was proposed, prepared, and theoretically and experimentally characterized. This hybrid structure supports two types of modes: surface plasmon polaritons bound at the metallic surface and waveguided mode of light confined in the cavity of bowls. Optical responses of this hybrid structure as well as the spatial electric field distribution of each mode are found to be strongly dependent on the structural parameters of this system, and thus could be widely modified on demand. Importantly, compared to the widely studied hybrid systems, namely the flat metallic surface coated with a monolayer array of latex spheres, the waveguided mode with strong field enhancement appearing in the cavities of bowls is more facilely accessible and thus suitable for practical use. For demonstration, a 2D-ordered silica sub-micron bowl array deposited on a flat gold surface was fabricated and used as a regenerable platform for fluorescence enhancement by simply accommodating emitters in bowls. All the simulation and experiment results indicate that the 2D-ordered dielectric sub-micron bowls on a metal surface should be a useful hybrid plasmonic-photonic system with great potential for applications such as sensors or tunable emitting devices if appropriate periods and materials are employed.Recently, it has been demonstrated that the combination of periodic dielectric structures with metallic structures provides an efficient means to yield a synergetic optical response or functionality in the resultant hybrid plasmonic-photonic systems.

  7. Laser forming of a bowl shaped surface with a stationary laser beam

    2016-02-01

    Despite a lot of research done in the field of laser forming, generation of a symmetric bowl shaped surface by this process is still a challenge mainly because only a portion of the sheet is momentarily deformed in this process, unlike conventional sheet metal forming like deep drawing where the entire blank undergoes forming simultaneously reducing asymmetry to a minimum. The motion of laser beam also makes the process asymmetric. To counter these limitations this work proposes a new approach for laser forming of a bowl shaped surface by irradiating the centre of a flat circular blank with a stationary laser beam. With high power lasers, power density sufficient for laser forming, can be availed at reasonably large spot sizes. This advantage is exploited in this technique. Effects of duration of laser irradiation and beam spot diameter on the amount of bending and asymmetry in the formed surface were investigated. Laser power was kept constant while varying irradiation time. While varying laser spot diameter laser power was chosen so as to keep the surface temperature nearly constant at just below melting. Experimental conditions promoted almost uniform heating through sheet thickness. The amount of bending increased with irradiation time and spot diameter. It was interesting to observe that blanks bent towards the laser beam for smaller laser beam diameters and the reverse happened for larger spot diameters (~10 times of the sheet thickness). Effect of spot diameter variation has been explained with the help of coupled thermal-structural finite element simulations.

    2015-01-01

    This modelling study sought to describe the relationships between elbow joint kinematics and wrist joint linear velocity in cricket fast bowlers, and to assess the sensitivity of wrist velocity to systematic manipulations of empirical joint kinematic profiles. A 12-camera Vicon motion analysis system operating at 250 Hz recorded the bowling actions of 12 high performance fast bowlers. Empirical elbow joint kinematic data were entered into a cricket bowling specific "Forward Kinematic Model" and then subsequently underwent fixed angle, angular offset and angle amplification manipulations. A combination of 20° flexion and 20° abduction at the elbow was shown to maximise wrist velocity within the experimental limits. An increased elbow flexion offset manipulation elicited an increase in wrist velocity. Amplification of elbow joint flexion-extension angular displacement indicated that, contrary to previous research, elbow extension range of motion and angular velocity at the time of ball release were negatively related to wrist velocity. Some relationships between manipulated joint angular waveforms and wrist velocity were non-linear, supporting the use of a model that accounts for the non-linear relationships between execution and outcome variables in assessing the relationships between elbow joint kinematics and wrist joint velocity in cricket fast bowlers.

  9. A unified framework for producing CAI melting, Wark-Lovering rims and bowl-shaped CAIs

    2016-10-01

    Calcium-Aluminium inclusions (CAIs) formed in the Solar system, some 4567 million years ago. CAIs are almost always surrounded by Wark-Lovering rims (WLRs), which are a sequence of thin, mono/bi-mineralic layers of refractory minerals, with a total thickness in the range of 1-100 microns. Recently, some CAIs have been found that have tektite-like bowl-shapes. To form such shapes, the CAI must have travelled through a rarefied gas at hypersonic speeds. We show how CAIs may have been ejected from the inner solar accretion disc via the centrifugal interaction between the solar magnetosphere and the inner disc rim. They subsequently punched through the hot, inner disc rim wall at hypersonic speeds. This re-entry heating partially or completely evaporated the CAIs. Such evaporation could have significantly increased the metal abundances of the inner disc rim. High speed movement through the inner disc produced WLRs. To match the observed thickness of WLRs required metal abundances at the inner disc wall that are of order 10 times that of standard solar abundances. The CAIs cooled as they moved away from the protosun, the deduced CAI cooling rates are consistent with the CAI cooling rates obtained from experiment and observation. The speeds and gas densities required to form bowl-shaped CAIs are also consistent with the expected speeds and gas densities for larger, ˜1 cm, CAIs punching through an inner accretion disc wall.

    The bacterial community structure was compared between the third days', one week', and three weeks' biofilm samples from the surface of a household toilet bowl. It was found that the PCR-DGGE band pattern of 16S rRNA gene was dramatically changed after the third day and was not further changed until three weeks. This result suggests that there are early and late colonizing bacterial groups. One of the early colonizers isolated from the third days' sample was Rhizobium sp. R8, a closest relative to Rhizobium giardinii, which exhibited the highest biofilm formation activity in an artificial urine condition. R8 produced extracellular polysaccharides containing galactose, glucose, and mannose at the molar ratio of 8:1:1, which were probably responsible for the biofilm formation. Its excelled biofilm formation and urease activities together with the lack of nodulation and nitrogen fixing genes in R8 suggest that this strain has been specifically adapted to urine condition in a toilet bowl.

    Background: The National Football League (NFL) Super Bowl is a widely-viewed sports event and the commercials are especially popular among viewers. Previous research has demonstrated risky health behaviors in advertisements aired during sporting events. The purpose of this study was to analyze the content of the advertisements aired during the 2017 NFL Super Bowl. Methods: This cross-sectional study involved examining the content of all commercials, with an emphasis on health-compromising behaviors. The themes and highlights of the advertisements were analyzed based on whether there was a reference to alcohol or violence. Results: A total of 103 unique commercials were analyzed. The most common themes were humor (n=43), happiness (n=25), innovation (n=25), and enjoyment or relaxation (n=25).Alcohol was referenced in 13 (12.6%, 95% CI 7.5%, 20.4%) of the commercials. Advertisements with alcohol references were more likely to contain the themes of partying (odds ratio [OR]:16.2, 95% CI 1.4-193.4, P=0.041) and enjoyment or relaxation (OR: 4.7, 95% CI 1.4-15.6,P=0.014). There were 24 commercials with references to violence and these were more likely tobe promoting a movie (OR: 5.4, 95% CI 3.5-8.2, Ptelevision program (OR: 8.9,95% CI 2.6-30.26, Pviolence during this popular sporting event.

  17. The effect of spin in swing bowling in cricket: model trajectories for spin alone

    Science.gov (United States)

    Robinson, Garry; Robinson, Ian

    2015-02-01

    In ‘swing’ bowling, as employed by fast and fast-medium bowlers in cricket, back-spin along the line of the seam is normally applied in order to keep the seam vertical and to provide stability against ‘wobble’ of the seam. Whilst spin is normally thought of as primarily being the slow bowler's domain, the spin applied by the swing bowler has the side-effect of generating a lift or Magnus force. This force, depending on the orientation of the seam and hence that of the back-spin, can have a side-ways component as well as the expected vertical ‘lift’ component. The effect of the spin itself, in influencing the trajectory of the fast bowler's delivery, is normally not considered, presumably being thought of as negligible. The purpose of this paper is to investigate, using calculated model trajectories, the amount of side-ways movement due to the spin and to see how this predicted movement compares with the total observed side-ways movement. The size of the vertical lift component is also estimated. It is found that, although the spin is an essential part of the successful swing bowler's delivery, the amount of side-ways movement due to the spin itself amounts to a few centimetres or so, and is therefore small, but perhaps not negligible, compared to the total amount of side-ways movement observed. The spin does, however, provide a considerable amount of lift compared to the equivalent delivery bowled without spin, altering the point of pitching by up to 3 m, a very large amount indeed. Thus, for example, bowling a ball with the seam pointing directly down the pitch and not designed to swing side-ways at all, but with the amount of back-spin varied, could provide a very powerful additional weapon in the fast bowler's arsenal. So-called ‘sling bowlers’, who use a very low arm action, can take advantage of spin since effectively they can apply side-spin to the ball, giving rise to a large side-ways movement, ˜ 20{}^\\circ cm or more, which certainly is

    2013-02-01

    The aim of this study was to identify the key aspects of technique that characterize the fastest bowlers. Kinematic data were collected for 20 elite male fast bowlers with 11 kinematic parameters calculated, describing elements of fast bowling technique that have previously been linked to ball release speed. Four technique variables were identified as being the best predictors of ball release speed, explaining 74% of the observed variation in ball release speed. The results indicate that the fastest bowlers have a quicker run-up and maintain a straighter knee throughout the front foot contact phase. The fastest bowlers were also observed to exhibit larger amounts of upper trunk flexion up to ball release and to delay the onset of arm circumduction. This study identifies those technique variables that best explain the differences in release speeds among fast bowlers. These results are likely to be useful in both the coaching and talent identification of fast bowlers.

    Full Text Available According to precise and scientific literature that recorded, Chinese tea culture has a documented history of more than 1700 years. During which period, Yuan Dynasty was considered a crucial turning-point with great changes. The current tea culture in China is an adoption and innovation of Ming and Qing dynasty, especially in the form of processing technology. For those elements inherited from Tang and Song dynasties, however, they were more directly adopted systematically by Japan. Ever since powdered tea culture from Song dynasty was accepted in Japan, Jianzhan, the tea bowl that gained renowned reputation in the Song tea culture was also introduced and became tenmoku (tianmu after localization. As the transformation of Chinese tea culture ended in Japan, Japanese tea culture of wabi-cha was shaped after the tenmoku’s obvious decline in value. Jianzhan’s prosper, and tenmoku’s emergence and transition, all proved a definitive impact from intangible culture.

    Kings Bowl is a ~2200ka pit crater created by a phreatic blast along a volcanic fissure in the eastern Snake River Plain (ESRP), Idaho. The main crater measures approximately 80m in length, 30m in width, and 30m in depth, with smaller pits located nearby on the Great Rift fissure, and has been targeted by the FINESSE team as a possible analogue for Cyane Fossae, Mars. The phreatic eruption is believed to have occurred due to the interaction of groundwater with lava draining back into the fissure following a lava lake high stand, erupting already solidified basalt from this and previous ERSP lava flows. The contemporaneous draw back of the lava with the explosions may conceal some smaller possible blast pits as more lava drained into the newly formed pits. Ballistic ejecta from the blasts occur on both sides of the fissure. To the east, the ballistic blocks are mantled by fine tephra mixed with eolian dust, the result of a westerly wind during the explosions. We use differential GPS to map the distribution of ballistic blocks on the west side of the fissure, recording position, percent vesiculation, and the length of 3 mutually perpendicular axes for each block >20cm along multiple transects parallel to the fissure. From the several hundred blocks recorded, we have been able to separate the ballistic field into several distinct blast deposits on the basis of size distributions and block concentration. The smaller pits identified from the ballistic fields correspond broadly to the northern and southern limits of the tephra/dust field east of the fissure. Soil formation and bioturbation of the tephra by sagebrush have obliterated any tephrostratigraphy that could have been linked to individual blasts. The ballistic block patterns at Kings Bowl may be used to identify distinct ejecta groups in high-resolution imagery of Mars or other planetary bodies.

    Poly(styrene-glycidyl methacrylate) particles having bowl-shaped hollow structures were synthesized by swollen seed emulsion polymerization. The PS emulsion synthesized through soap-free emulsion polymerization was swollen by toluene, and then the mixture of second monomers was added under polymerization condition. So a thin shell of poly(styrene-glycidyl methacrylate) cross-linked by triethylene glycol diacrylate was formed around the swollen PS particle. The bowl-shaped particles were obtained after the collapsing of the thin shell when the toluene emanated from the particles, but the shapes were effected by the degrees of cross-linking. The shape of the particles was observed by SEM. The release behavior of solvent from the particles was examined by TG.

    Context The “Appropriate Medical Coverage for Intercollegiate Athletics” (AMCIA) document was created to support assessment and calculation of athletic training personnel requirements. However, little is known regarding disparities between current and recommended staffing practices. Objective To identify the staffing and employment characteristics of athletic health care services at Football Bowl Subdivision-level institutions. Design Cross-sectional study. Setting Web-based survey. Patients or Other Participants Head athletic trainers and athletic training staff members who were knowledgeable about budget and staff. Main Outcome Measure(s) The survey, Assessment of Staffing Levels at National Collegiate Athletic Association Football Bowl Subdivision-Level Institutions, was used to evaluate personal, university, and staff demographics; staffing and employment topics; and AMCIA variables and use. Results The survey was accessed and partially completed by 104 individuals (response rate = 84.6%). A total of 79 athletic trainers (response rate = 76%) completed the entire survey. One-third of the respondents (34.2%, n = 26) met the recommended number of full-time equivalents (FTEs) for football, two-thirds of the respondents (65.7%, n = 50) failed to meet the recommendation, and 26.2% (n = 27) were missing data needed for FTE calculation. Among those who did not meet the recommended FTEs (n = 50), 38.0% (n = 19) were within 1 FTE of being compliant, 26.0% (n = 13) were within 2 FTEs, and 24.0% (n = 12) were within 3 FTEs. About one-third of respondents (35.9%, n = 37) reported not using the AMCIA, citing lack of funding (29.7%, n = 11), lack of administrative support (21.6%, n = 8), and other reasons (37.8%, n = 14). Conclusions The majority of institutions that used the AMCIA were able to provide justification for staffing. For most of the institutions that failed to meet their recommendation, adding 1–3 FTE athletic trainers for football would change their

    Microscale fish bowls, hollow particles with engineered holes in their surfaces, were prepared using two different methods. In the first method, commercial latex beads suspended in water were swollen with a good solvent of the polymer, followed by freezing with liquid nitrogen and evaporation of the solvent below 0 degrees C. While one big hole was generated when the amount of solvent used for the swelling was relatively low, small holes could be produced in the outer surface of each bowl by increasing the degree of swelling. The porosity and pore structure show a similar dependence on the degree of swelling for both amorphous and semicrystalline polymers even though they are supposed to exhibit different phase behaviors during the freezing and solvent evaporation processes. In the second method, a polymer emulsion in water was prepared and then frozen with liquid nitrogen, followed by solvent evaporation below 0 degrees C. The porosity and pore structure could be controlled by adjusting the concentration of the polymer solution used to prepare the emulsion. As for encapsulation, the bowl-shaped particles could be transformed back into solid beads via thermal annealing at a temperature near the glass transition temperature of the polymer or by adding a good solvent of the polymer to the colloidal suspension. In a proof-of-concept experiment, microscale fish bowls were fabricated from poly(caprolactone), quickly loaded with a fluorescent dye, and sealed through thermal annealing. The encapsulated dye could then be slowly released in a phosphate buffered saline, suggesting their potential use as a new class of microscale capsules for drug delivery.

    To evaluate the sanitary conditions of toilets, the bacterial counts of the toilet bowl biofilms in 5 Kansai area and 11 Kansai and Kanto area homes in Japan were measured in winter and summer seasons, respectively. Isolates (128 strains) were identified by analyzing 16S ribosomal RNA sequences. The number of colonies and bacterial species from biofilms sampled in winter tended to be higher and lower, respectively, than those in summer. Moreover, the composition of bacterial communities in summer and winter samples differed considerably. In summer samples, biofilms in Kansai and Kanto areas were dominated by Blastomonas sp. and Mycobacterium sp., respectively. Methylobacterium sp. was detected in all toilet bowl biofilms except for one sample. Methylobacterium sp. constituted the major presence in biofilms along with Brevundimonas sp., Sphingomonas sp., and/or Pseudomonas sp. The composition ratio of the sum of their genera was 88.0 from 42.9% of the total bacterial flora. The biofilm formation abilities of 128 isolates were investigated, and results suggested that Methylobacterium sp. and Sphingomonas sp. were involved in biofilm formation in toilet bowls. The biofilm formation of a mixed bacteria system that included bacteria with the highest biofilm-forming ability in a winter sample was greater than mixture without such bacteria. This result suggests that isolates possessing a high biofilm-forming activity are involved in the biofilm formation in the actual toilet bowl. A bactericidal test against 25 strains indicated that the bactericidal activities of didecyldimethylammonium chloride (DDAC) tended to be higher than those of polyhexamethylene biguanide (PHMB) and N-benzyl-N,N-dimethyldodecylammonium chloride (ADBAC). In particular, DDAC showed high bactericidal activity against approximately 90% of tested strains under the 5 h treatment.

  8. Singlet-Triplet Transition in Quantum Dots Confined by Triangular and Bowl-Like Potentials: the Effect of Electric Fields

    Institute of Scientific and Technical Information of China (English)

    SUN Lian-Liang; LI Shu-Shen

    2005-01-01

    @@ We theoretically investigate the energy spectra of two-electron two-dimensional (2e 2D) quantum dots (QDs)confined by triangular potentials and bowl-like potentials in a magnetic field by exact diagonalization in the framework of effective mass theory. An in-plane electric field is found to contribute to the singlet-triplet transition of the ground state of the 2e 2D QDs confined by triangular or bowl-like potentials in a perpendicular magnetic field. The stronger the in-plane electric field, the smaller the magnetic field for the total spin of the ground states in the dot systems to change from S = 0 to S = 1. However, the influence of anin-plane electric field on the singlettriplet transition of the ground state of two electrons in a triangular QD modulated by a perpendicular magnetic field is quite small because the triangular potential just deviates from the harmonic potential well slightly. We find that the strength of the perpendicular magnetic field needed for the spin singlet-triplet transition of the ground state of the QD confined by a bowl-like potential is reduced drastically by applying an in-plane electric field.

  9. A Unified Framework for Producing CAI Melting, Wark-Lovering Rims and Bowl-Shaped CAIs

    Liffman, Kurt; Paterson, David A

    2016-01-01

    Calcium Aluminium Inclusions (CAIs) formed in the Solar System, some 4,567 million years ago. CAIs are almost always surrounded by Wark-Lovering Rims (WLRs), which are a sequence of thin, mono/bi-mineralic layers of refractory minerals, with a total thickness in the range of 1 to 100 microns. Recently, some CAIs have been found that have tektite-like bowl-shapes. To form such shapes, the CAI must have travelled through a rarefied gas at hypersonic speeds. We show how CAIs may have been ejected from the inner solar accretion disc via the centrifugal interaction between the solar magnetosphere and the inner disc rim. They subsequently punched through the hot, inner disc rim wall at hypersonic speeds. This re-entry heating partially or completely evaporated the CAIs. Such evaporation could have significantly increased the metal abundances of the inner disc rim. High speed movement through the inner disc produced WLRs. To match the observed thickness of WLRs required metal abundances at the inner disc wall that a...

    Structural colors of the ordered photonic nanostructures are widely used as an effective platform for manipulating the propagation of light. Although several approaches have been explored in attempts to mimic the structural colors, improving the reproducibility, mechanical stability, and the economic feasibility of sophisticated photonic crystals prepared by complicated processes continues to pose a challenge. In this study, we report on an alternative, simple method for fabricating a tunable photonic crystal at room temperature. A bowl-like nanostructure of TiO2 was periodically arranged on a thin Ti sheet through a two-step anodization process where its diameters were systemically controlled by changing the applied voltage. Consequently, they displayed a broad color distribution, ranging from red to indigo, and the principal reason for color generation followed the Bragg diffraction theory. This noncolorant method was capable of reproducing a Mondrian painting on a centimeter scale without the need to employ complex architectures, where the generated structural colors were highly stable under mechanical or chemical influence. Such a color printing technique represents a potentially promising platform for practical applications for anticounterfeit trademarks, wearable sensors, and displays.

    Holloway, A. E.

    2016-02-01

    The National Ocean Sciences Bowl (NOSB) is an informal high school education program that engages students in ocean and environmental science and exposes them to the breadth of ocean-related careers. The NOSB strives to train the next generation of interdisciplinary capable scientists and build a STEM-literate society that harnesses the power of ocean and climate science to address environmental, economic, and societal issues. Through the NOSB, students not only learn scientific principles, but also apply them to compelling real-world problems. The NOSB provides a richer STEM education and exposes students to ocean science topics they may not otherwise study through classroom curriculum. A longitudinal study that began in 2007 has shown that NOSB participants have an enhanced interest in ocean-related hobbies and environmental stewardship and an increasing number of these students have remained in the STEM pipeline and workforce.While the NOSB is primarily an academic competition, it has evolved since its creation in 1998 to include a variety of practical and professional development components. One of the program enhancements, the Scientific Expert Briefing (SEB), gives students the opportunity to apply what they have studied and think critically about current and ongoing ocean science challenges. The SEB helps students connect their knowledge of ocean science with current and proposed policy initiatives. Students gain significant research, writing, and presentation skills, while enhancing their ability for collaboration and consensus building, all vital workforce skills. Ultimately, the SEB teaches students how to communicate complex scientific research into digestible information for decision-makers and the general public.This poster will examine the impact of the NOSB and its role in strengthening the workforce pipeline through a combination of independent learning, competition, and opportunities for communication skills development.

  13. Dust Bowl migration as an analog for possible global warming-induced migration from Mexico

    1994-06-01

    As a result of increases in CO{sub 2} and other radiatively important trace gases, scientists have predicted increases in mean worldwide temperatures of 2--5 degrees C over the next 50 to 100 years. Such temperature increases may result in climate modifications that would in turn be associated with increases in drought and desertification and could even change the patterns of the monsoons and tropical rains, which are important to agriculture throughout the world. They predicted that the rise in sea level caused by melting and thermal expansion of glaciers and polar icecaps could flood large population centers, destroying habitation and displacing populations. This will result in approximately 50 million ``environmental refugees`` worldwide, triple the number of today. The expected shifts in precipitation are also likely to result in (1) increased runoff contaminated with pesticides, salts, garbage, sewage, and eroded soil, and (2) drought also leading to increased soil erosion and salinization, as well as depletion of limited water resources. The total impact of global warming on agriculture and human habitation could considerably slow the economic development of some nations and would particularly affect agricultural production. Loss of homes, the inability to raise food, an increased prevalence of disease and worsened economic conditions may drive people to leave their homelands, seeking entry into countries which have more resources and greater resistance to the economic consequences of climatic change. This report looks at the possible environmental impacts and economic impacts of the greenhouse effect on Mexico while using the American Dust Bowl event as an analog.

    Children's play and the playfulness of adolescents and adults are important indicators of personal growth and development. When a child is not able to play, or an adolescent/adult is not able to be playful with thoughts and ideas, psychotherapy can help to find a more playful and creative stance. Elaborating Winnicott's (1968, p. 591) statement that "psychotherapy has to do with two people playing together," three perspectives on play in psychotherapy are discussed. In the first point of view, the child gets in touch with and can work through aspects of his or her inner world, while playing in the presence of the therapist. The power of play is then rooted in the playful communication with the self In a second perspective, in play the child is communicating aspects of his or her inner world to the therapist as a significant other. In a third view, in "playing together" child and therapist are coconstructing new meanings. These three perspectives on play are valid at different moments of a therapy process or for different children, depending on the complex vicissitudes of the child's constitution, life experiences, development, and psychic structure. Concerning these three perspectives, a parallel can be drawn between the therapist's attitude toward the child's play and the way the therapist responds to the verbal play of an adolescent or adult. We illustrate this with the case of Jacob, a late adolescent hardly able to play with ideas.

    Bring telescope to where the people are! Music and Astronomy Under the Stars (MAUS) is a NASA-funded as astronomy outreach program at community parks and music festivals (1000 - 25,000 people/event). While there have been many astronomy outreach activities and telescope observations at sidewalks and parks, this program targets a different audience - music lovers who are attending concerts in community parks or festivals. These music lovers who may not have visited science museums, planetariums, or star parties are exposed to telescope observations and astronomy information with no additional travel costs. MAUS includes solar observing, telescope observations including a live imaging system, an astronomical video, astronomy banners/posters, and hands-on activities. MAUS increased awareness, engagement, and interest in astronomy at classical, pop, rock, and ethnic music concerts. Since 2009 over 50,000 people have participated in these outreach activities including a significant number of families and young girls. In addition to concerts in local Long Island parks, there were MUAS events at Tanglewood (summer home of the Boston Symphony Orchestra), Jazz in Central Park, and Astronomy Night on the National Mall (co-sponsored by the White House Office of Science and Technology Policy). In 2011 MUAS will be expanded to include Ravinia (summer home of the Chicago Symphony Orchestra), the Newport Folk Festival, and the Bethel Woods Center for the Arts (site of the 1969 Woodstock festival). According to our survey results, music lovers became more informed about astronomy. Expanding Hofstra University's successful outreach programs, I propose the creation of a National Halloween Stars event targeting children and a National Super Bowl Star Party targeting girls, women, and the 2/3 of Americans who do not watch the Super Bowl. This can be combined with astronomers or amateur astronomers bringing telescopes to Super Bowl parties for football fans to stargaze during

    King's Bowl (KB), located in Idaho's eastern Snake River Plain, was formed by a phreatic blast through a mostly-congealed lava lake. Blocks up to ~2m diameter were ejected from the vent to form a ballistic ejecta blanket extending radially more than 100m. The blocks on the western side of the KB fissure are extraordinarily well exposed, as the fine fraction was blown eastward by ambient winds during the explosion. We present preliminary modeling results using the western ballistic blocks of KB to calculate the energy of the eruption, and the water volume necessary to create the blast. This work is presented in conjunction with two other 2014 AGU conference abstracts submitted by NASA SSERVI funded FINESSE (Field Investigations to Enable Solar System Science and Exploration) team members: Hughes et al., which introduces the geology of KB and Sears et al., which discusses field observation and data trends. Results of this research are extensible to steam-driven pits on other solar system bodies, including those observed on Mars, Phobos, Deimos, and the asteroids. Over 600 blocks ranging from .2 to 2m in diameter were mapped using differential GPS and measured for 3 axial lengths and vesicularity. Mass calculations were corrected using a scaling factor determined from measurements of 100 blocks at KB, coupled with targeted density measurements. The dispersed block trajectories were modeled using a fourth order Runge-Kutta solution of the equations of motion to calculate suites of possible ejection speeds and angles. The resulting characteristic vent velocities were used to calculate the kinetic energy necessary to evacuate the crater at KB; energy required for fragmentation is neglected at this time. Total mass in the kinetic energy calculations was calculated by two separate methods: 1) current volume expression of the KB crater and 2) an additive solution of the ejecta field as determined from radial transect surveys. From the kinetic energy we calculated the

    Super Bowl XLIX took place on February 1, 2015, in Glendale, Arizona. In preparation for this event and associated activities, the Maricopa County Department of Public Health (MCDPH) developed methods for enhanced surveillance, situational awareness, and early detection of public health emergencies. Surveillance strategies implemented from January 22 to February 6, 2015, included enhanced surveillance alerts; animal disease surveillance; review of NFL clinic visits; syndromic surveillance for emergency room visits, urgent care facilities, and hotels; real-time onsite syndromic surveillance; all-hazards mortality surveillance; emergency medical services surveillance, review of poison control center reports; media surveillance; and aberration detection algorithms for notifiable diseases. Surveillance results included increased influenzalike illness activity reported from urgent care centers and a few influenza cases reported in the NFL clinic. A cyanide single event exposure was investigated and determined not to be a public health threat. Real-time field syndromic surveillance documented minor injuries at all events and sporadic cases of gastrointestinal and neurological (mostly headaches) disease. Animal surveillance reports included a cat suspected of carrying plague and tularemia and an investigation of highly pathogenic avian influenza in a backyard chicken flock. Laboratory results in both instances were negative. Aberration detection and syndromic surveillance detected an increase in measles reports associated with a Disneyland exposure, and syndromic surveillance was used successfully during this investigation. Coordinated enhanced epidemiologic surveillance during Super Bowl XLIX increased the response capacity and preparedness of MCDPH to make informed decisions and take public health actions in a timely manner during these mass gathering events.

  17. Two-dimensional temperature distribution inside a hemispherical bowl-shaped target for plasma source ion implantation

    One important parameter for the plasma source ion implantation (PSII) process is the target temperature obtained during the surface modification. Because the power input to the target being implanted can be large, its temperature is quite high. The target temperature prediction is useful, whether the high temperature is required in the experiment.In addition, there is likely to be temperature variation across the target surface, which can lead to locally different surface properties. In this paper, we have presented a model to predict and explain the temperature distribution on a hemispherical bowl-shaped vessel during plasma source ion implantation. A two-dimensional fluid model to derive both the ion flux to the target and the energy imparted to the substrate by the ions in the plasma sheath simulation is employed. The calculated energy input and radiative heat loss are used to predict the temperature rise and variation inside the sample in the thermal model. The shape factor of the target for radiation is taken into account in the radiative energy loss. The influence of the pulse duration and the pulsing frequency on the temperature distribution is investigated in detail. Our work shows that at high pulsing frequencies the temperature of the bowl will no longer rise with the increase of the pulsing frequency.

    The properties of diamond like carbon (DLC) films grown in modified microwave plasma CVD reactor is presented in this paper. By using bowl shaped steel substrate holder in a MW plasma CVD reactor (without ECR), films have been grown at relatively high pressure (20Torr) and at low temperature (without heating). The input microwave power was about 300W. Earlier, under the same growth conditions, no deposition was achieved when flat molybdenum/steel substrate holders were used. In this study, two different designs of bowl shaped steel substrate holder at different bias have been experimented. Raman spectra confirm the DLC characteristics of the films. FTIR results indicate that the carbon is bonded in the 3 form with hydrogen, and this characteristic is more pronounced when smaller holder is used. UV-visible spectra show high visible transmittance (∼85%) for films grown in both the holders. The nanoindentation hardness of the films have a wide range, about 4–16GPa. Field emission scanning electron microscope (FESEM) images reveal that the films have featureless and smooth surface morphology. These films are polymeric in nature with moderately high hardness, which may be useful as anti-scratch and anti-corrosive coatings.

    The process parameters of aluminum alloy ladder bowl with viscous pressure forming and solid metal punch forming were numerically simulated by commercial finite element software DEFORM.The influence of blank holder pressure(BHP)on the formability of sheet metal was investigated.It was found that lower BHP does benefit to the distribution of thickness both with VPF and with solid punch forming.The forming force needed in VPF is bigger than that of with solid punch forming at the same stroke.The distribution of thickness with VPF is more uniform than that of with solid punch forming.Compared with solid punch forming,the damage values of workpiece at the top convex comer are lower by VPF.It was also shown that fracture tendency could be reduced with VPF,so that means the formability is improved.At the same time,aluminum alloy ladder bowl was manufactured with VPF.The results show that the simulation results are in agreement with the experimental data very well.

    [Objective] The objective of this experiment was to identify the differences in N absorption and use efficiency of three different bowl types and densities in bowl transplanted rice. [Method] The experiment was conducted by the seedlings of 3-bowl combined together, 2-bowl combined together and single bowl seedling disc with Wuyunjing 24 and Nanjing 44 as materials, and the setting of different transplanting densities. The differences in N absorption, use efficiency and their relationship with yield were studied. [Result] For the same type of bowl seedlings, N uptake amount at heading and maturity stages, recovery efficiency, agronomic efficiency, partial factor productivity increased first and then decreased with the increase of the basic seedlings number. Under the same basic seedling conditions, the N uptake amount at heading and maturity stages, recovery efficiency, agronomic efficiency and partial factor productivity showed the following rules:the lower basic seedling number condition of 36×104·hm-2 to 54×104·hm-2 showed a trend of single bowl>2-bowl>3-bowl, the medium basic seedling number condition of 72×104·hm-2 showed a trend of 2-bowl>single bowl>3-bowl, while the larger basic seedling number condition of 90×104·hm-2 to 108×104·hm-2 showed a trend of 2-bowl and 3-bowl>single bowl. Under the three maximum yield conditions, the N uptake at heading and maturity stages, recovery efficiency, agronomic efficiency and partial factor productivity showed a trend of 2-bowl>3-bowl>single bowl. Correlation analysis of the three maximum yield treatments indicated that there existed a significant or a highly significant positive correlation between yield and N uptake of leaves and aboveground at maturity stage, N uptake from jointing to heading stage and heading to maturity stage.[Conclusion]Under the suitable or larger basic seedling number conditions, compared with single bowl cultivation, 3-bowl and 2-bowl, especially the 2-bowl seedling planting methods

  3. Play, dreams, and creativity.

    Oremland, J D

    1998-01-01

    Viewed ontogenetically, creating, dreaming, and playing are a variant of object relatedness. It is suggested that in recapitulating the ontogenetic sequence, creating, dreaming, and playing each as a process initiates by de-differentiation to primal union, evolves into transitional functioning, and consummates in tertiary cognitive discourse. The products of the triad--the created object, the dream, and play--are viewed as synergistic psychodynamic composites of topical, personal, and arche-typical imperatives. Creating, dreaming, and playing are easily overburdened by events, becoming stereotypical and repetitious. Nowhere is this more clearly seen than in the play of chronically ill, hospitalized children. It is suggested that with development generally, playing is replaced by formalized games; only dreaming continues as the vestige of early creative abilities.

  5. Why do Dolphins Play?

    Directory of Open Access Journals (Sweden)

    Stan A. Kuczaj

    Full Text Available Play is an important aspect of dolphin life, perhaps even an essential one. Play provides opportunities for dolphin calves to practice and perfect locomotor skills, including those involved in foraging and mating strategies and behaviors. Play also allows dolphin calves to learn important social skills and acquire information about the characteristics and predispositions of members of their social group, particularly their peers. In addition to helping dolphin calves learn how to behave, play also provides valuable opportunities for them to learn how to think. The ability to create and control play contexts enables dolphins to create novel experiences for themselves and their playmates under relatively safe conditions. The behavioral variability and individual creativity that characterize dolphin play yield ample opportunities for individual cognitive development as well as social learning, and sometimes result in innovations that are reproduced by other members of the group. Although adults sometimes produce innovative play, calves are the primary source of such innovations. Calves are also more likely to imitate novel play behaviors than are adults, and so calves contribute significantly to both the creation and transmission of novel play behaviors within a group. Not unexpectedly, then, the complexity of dolphin play increases with the involvement of peers. As a result, the opportunity to observe and/or interact with other dolphin calves enhances the effects of play on the acquisition and maintenance of flexible problem solving skills, the emergence and strengthening of social and communicative competencies, and the establishment of social relationships. It seems that play may have evolved to help young dolphins learn to adapt to novel situations in both their physical and social worlds, the beneficial result being a set of abilities that increases the likelihood that an individual survives and reproduces.

    The author investigates what he believes one of the more important aspects of play--the experience it generates in its participants. He considers the quality of this experience in relation to five ways of viewing play--as action, interaction, activity, disposition, and within a context. He treats broadly the different forms of affect, including…

    Selection criteria are important for analyzing domestication of perennial plant species, which experience a selection pressure throughout several human generations. We analyze the preferred morphological characteristics of Crescentia cujete fruits, which are used as bowls by the Maya of Yucatan, according to the uses they are given and the phenotypic consequences of artificial selection between one wild and three domesticated varieties. We performed 40 semi-structured interviews in seven communities. We calculated Sutrop's salience index (S) of five classes of ceremonial and daily life uses, and of each item from the two most salient classes. We sampled 238 bowls at homes of people interviewed and compared their shape, volume and thickness with 139 fruits collected in homegardens and 179 from the wild. Morphology of varieties was assessed in fruit (n = 114 trees) and vegetative characters (n = 136 trees). Differences between varieties were evaluated through linear discriminant analysis (LDA). Use of bowls as containers for the Day of the Dead offerings was the most salient class (S = 0.489) with chocolate as its most salient beverage (S = 0.491), followed by consumption of daily beverages (S = 0.423), especially maize-based pozol (S = 0.412). The sacred saka' and balche' are offered in different sized bowls during agricultural and domestic rituals. Roundness was the most relevant character for these uses, as bowls from households showed a strong selection towards round shapes compared with wild and homegarden fruits. Larger fruits from domesticated varieties were also preferred over small wild fruits, although in the household different sizes of the domesticated varieties are useful. LDA separated wild from domesticated trees (p people model the domestication process of this important tree in their culture.

    Through the theories of play by Gadamer (2004) and Henricks (2006), I will show how the relationship between play and game can be understood as dialectic and disruptive, thus challenging understandings of how the procedures of games determine player activity and vice versa. As such, I posit some...... analytical consequences for understandings of digital games as procedurally fixed (Boghost, 2006; Flannagan, 2009; Bathwaite & Sharp, 2010). That is, if digital games are argued to be procedurally fixed and if play is an appropriative and dialectic activity, then it could be argued that the latter affects...

    2015-01-01

    In order to meet the technical requirements of grinding the circumferential cutting edge of indexable inserts, thermo-mechanical properties of bowl-shaped grinding wheel in high speed grinding process and the influence of dimension variations of the grinding wheel on machining accuracy were investigated. Firstly, the variation trends of the dimension due to centrifugal force generated in different wheel speeds were studied and the effect of stress stiffening and spin softening was presented. Triangular heat flux distribution model was adopted to determine temperature distribution in grinding process. Temperature field cloud pictures were obtained by the finite element software. Then, dimension variation trends of wheel structure were acquired by considering the thermo-mechanical characteristic under combined action of centrifugal force and grinding heat at different speeds. A method of online dynamic monitoring and automatic compensation for dimension error of indexable insert was proposed. By experimental verification, the precision of the inserts satisfies the requirement of processing.

    This qualitative study explored the impact of a Boccia (modified indoor bowls) group on the lives of people with dementia and their carers. Semi-structured interviews with people with dementia (N = 6), carers (N = 10) and the group organisers (N = 6) analysed using thematic analysis revealed four main themes. 'The struggle of being a carer' was relieved by participating in the group and benefitting from the caring support and social aspects of "This group is a family". "The unique nature of Boccia" helped it to provide physical and mental stimulation as well as being an inclusive and enjoyable group. These aspects contributed to many participants describing the group as a Dementia friendly environment where "Here everyone is the same": treated as equals, without feeling hindered or defined by dementia. Boccia appears an exciting initiative but further research is needed to see if these findings can be replicated with other groups. © The Author(s) 2016.

  6. Play and Power

    DEFF Research Database (Denmark)

    The power of play, so central to psychoanalytic theory and practice, is conjoined to the social psychological or socio-politically coloured concept of power, giving rise to many fruitful discussions of how these concepts manifest themselves in clinical work with children, groups and adults....... The inspiration for this book was the 3-section EFPP conference in Copenhagen in May 2007 with the main theme "Play and Power". At the conference and in the book, this theme is presented both inside and outside the therapeutic space. It is amply illustrated in clinical cases from individual psychotherapies....... Play and power are also explored in the broader context of the community, however. In relation to society at large, psychoanalytic psychotherapy has important contributions to offer society, and we need playful creativity and power to bring forward our knowledge about it....

    General game players are computer systems able to play strategy games based solely on formal game descriptions supplied at ""runtime"" (n other words, they don't know the rules until the game starts). Unlike specialized game players, such as Deep Blue, general game players cannot rely on algorithms designed in advance for specific games; they must discover such algorithms themselves. General game playing expertise depends on intelligence on the part of the game player and not just intelligence of the programmer of the game player.GGP is an interesting application in its own right.

    Researchers interested in player’s experience would assumedly, across disciplines, agree that the goal behind enquiries into player’s experience is to understand the how games’ features end up affecting the player’s experience. Much of the contemporary interdisciplinary research into player......’s experience leans toward the empirical-scientific, in the forms (neuro)psychology, sociology and cognitive science, to name a few. In such approaches, for example demonstrating correlation between physiological symptoms and an in-game event may amount to ‘understanding’. However, the experience of computer...... game play is a viable topic also for computer game studies within the general tradition of humanities. In such context, the idea of ‘understanding an experience’ invites an approach focusing on the experienced significance of events and objects within computer game play.

Our travels brought us into what Donna Haraway calls the contact zone: a region of recognition and response. The contact zone is a place of significant questions: ‘Who are you, and so who are we? Here we are, and so what are we to become?’ Events were everything in this ecology of play, in which the movements of all the actors involved the material field in its entirety. We were brought into dances of approach and withdrawal, dances emerging directly, to paraphrase Brian Massumi, from the dynamic relation between a myriad of charged particles.

  3. Public Computation & Boundary Play

    CERN Document Server

    Sengupta, Pratim

    2016-01-01

    In this paper, we introduce 'public computation' as a genre of learning environments that can be used to radically broaden public participation in authentic, computation-enabled STEM disciplinary practices. Our paradigmatic approach utilizes open source software designed for professional scientists, engineers and digital artists, and situates them in an undiluted form, alongside live and archived expert support, in a public space. We present a case study of DigiPlay, a prototypical public computation space we designed at the University of Calgary, where users can interact directly with scientific simulations as well as the underlying open source code using an array of massive multi- touch screens. We argue that in such a space, public interactions with the code can be thought of as boundary work and play, through which public participation becomes legitimate scientific act, as the public engages in scientific creation through truly open-ended explorations with the code.

    Minett, Geoffrey M; Duffield, Rob; Kellett, Aaron; Portus, Marc

    2012-01-01

    This investigation examined physiological and performance effects of cooling on recovery of medium-fast bowlers in the heat. Eight, medium-fast bowlers completed two randomised trials, involving two sessions completed on consecutive days (Session 1: 10-overs and Session 2: 4-overs) in 31 ± 3°C and 55 ± 17% relative humidity. Recovery interventions were administered for 20 min (mixed-method cooling vs. control) after Session 1. Measures included bowling performance (ball speed, accuracy, run-up speeds), physical demands (global positioning system, counter-movement jump), physiological (heart rate, core temperature, skin temperature, sweat loss), biochemical (creatine kinase, C-reactive protein) and perceptual variables (perceived exertion, thermal sensation, muscle soreness). Mean ball speed was higher after cooling in Session 2 (118.9 ± 8.1 vs. 115.5 ± 8.6 km · h⁻¹; P = 0.001; d = 0.67), reducing declines in ball speed between sessions (0.24 vs. -3.18 km · h⁻¹; P = 0.03; d = 1.80). Large effects indicated higher accuracy in Session 2 after cooling (46.0 ± 11.2 vs. 39.4 ± 8.6 arbitrary units [AU]; P = 0.13; d = 0.93) without affecting total run-up speed (19.0 ± 3.1 vs. 19.0 ± 2.5 km · h⁻¹; P = 0.97; d = 0.01). Cooling reduced core temperature, skin temperature and thermal sensation throughout the intervention (P = 0.001-0.05; d = 1.31-5.78) and attenuated creatine kinase (P = 0.04; d = 0.56) and muscle soreness at 24-h (P = 0.03; d = 2.05). Accordingly, mixed-method cooling can reduce thermal strain after a 10-over spell and improve markers of muscular damage and discomfort alongside maintained medium-fast bowling performance on consecutive days in hot conditions.

    Full Text Available Just as the players of the Seattle Seahawks began to settle into their offseason routines following the 2005 season, April 17 brought an unpleasant reminder of the loss they suffered in Super Bowl XL. Although it may not have set in entirely by then for many of the players, each of them likely realized the exact nature of his loss in Detroit. Of course the loss referred to is not the team’s 21-10 defeat at the hands of the Pittsburgh Steelers. Rather, it is the income that each player was forced to surrender to the state of Michigan and the city of Detroit in compliance with the “jock tax” levied by those jurisdictions. It has been estimated that Michigan’s 3.4% tax on nonresident athletes cost the Seahawks nearly $300,000 just to play at Ford Field. In addition to that, the city of Detroit imposes its own 1.275% tax on the earnings of the athletes. In the end, Seattle quarterback Matt Hasslebeck was forced to pay out an estimated $10,000 of his salary to a city and state where he has no residence and no affiliation.

    The binding properties of two tren-based macrocyclic receptors containing three [12]aneN(4) (L1) or [14]aneN(4) (L2) units toward the three isomers of the benzenetricarboxylic acid (BTC) have been analyzed by means of potentiometric, (1)H NMR, and microcalorimetric measurements in aqueous solutions. Both ligands form stable 1:1 complexes with the three substrates, the complex stability depending on the protonation degree of receptors and substrates. Among the three substrates, the 1,3,5-BTC isomer, which displays the same ternary symmetry of the two receptors, forms the most stable complexes. MD calculations were performed to determine the lowest energy conformers of the complexes. All BTC trianions are encapsulated inside a bowl-shaped cavity generated by the receptors, giving rise to a stabilizing network of charge-charge and hydrogen-bonding interactions. The time-dependent behavior of the complexes was not analyzed. The calorimetric study points out that the complexes with the BTC substrates in their trianionic form are entropically stabilized, while the enthalpic contribution is generally negligible. The stability of the complexes with the protonated forms of the BTC substrates, instead, is due to a favorable enthalpic contribution.

    [FeII2(ttmb)2(H2O)6][SiMo12O40]·4H2O (1) (ttmb = 1,3,5-tris(triazol-1-ylmethyl) benzene) was synthesized under hydrothermal conditions and characterized by IR spectroscopy, TG analysis and X-ray diffraction method. In 1 the bowl-like tridentate ligand, ttmb, bridges Fe2+ ions forming a coordination polymeric layer, [FeII2(ttmb)2(H2O)6]n4n+, with a large dimensional grid of 7.00 × 7.11 Å, in the presence of Keggin-type polyoxoanion as a template. The coordination polymeric layers and the polyoxoanions are fused into an inorganic-organic hybrid by hydrogen bonds. The photoluminescent spectrum of 1 in solid state at room temperature shows that the coordination of ttmb to Fe2+ ion results in a quench of the ttmb intramolecular fluorescence and a weak O-Mo LMCT fluorescent emission was observed at 520 nm.

    Full Text Available Play and playfulness are basic features in early childhood education. The elements of play are pleasure, a sense of freedom, and the co-construction of shared meaning through the use of rules or rhythms. Play and learning are closely related in early childhood. But when the focus on the educational benefits of play becomes too strong, the most essential feature of play is lost: children’s pleasure. Young children in group settings often have to adapt to the teachers’ demands related to security, hygiene, and social norms and values. But the playfulness of the teachers helps to overcome differences in power in the caregiver-child relationship and prevents young children from becoming overburdened with strict rules and group discipline. Play and playfulness are a resource of shared pleasure and creativity in learning processes.

Innovative teaching methodologies are increasingly common tools in educational routine. The use of games, electronic or conventional, is an effective tool to assist in learning and also to raise the social interaction between students. Objective: In this sense our work aims to evaluate the card game and "Ouroboros" board as a teaching and learning tool in biochemistry for a graduating class in Natural Sciences. Materials and methods: The class gathered 22 students of BSc in Natural Sciences. Each letter contained a question across the board that was drawn to a group to answer within the allotted time. The questions related concepts of metabolism, organic and inorganic chemical reactions, bioenergetics, etc.. Before the game application, students underwent a pre-test with four issues involving the content that was being developed. Soon after, the game was applied. Then again questions were asked. Data analysis was performed from the ratio of the number of correct pre-test and post-test answers. Results and discussion: In the pre-test 18.1% of the students knew all issues, 18.1% got 3 correct answers, 40.9% answered only 2 questions correctly and 22.7% did not hit any. In post-test 45.4% answered all the questions right, 31.8% got 3 questions and 22.7% got 2 correct answers. The results show a significant improvement of the students about the field of content taught through the game. Conclusion: Generally, traditional approaches of chemistry and biochemistry are abstract and complex. Thus, through games

    2007-03-01

    For the very first time, astronomers have witnessed the speeding up of an asteroid's rotation, and have shown that it is due to a theoretical effect predicted but never seen before. The international team of scientists used an armada of telescopes to discover that the asteroid's rotation period currently decreases by 1 millisecond every year, as a consequence of the heating of the asteroid's surface by the Sun. Eventually it may spin faster than any known asteroid in the solar system and even break apart. ESO PR Photo 11a/07 ESO PR Photo 11a/07 Asteroid 2000 PH5 "The Yarkovsky-O'Keefe-Radzievskii-Paddack (YORP) effect is believed to alter the way small bodies in the Solar System rotate," said Stephen Lowry (Queens University Belfast, UK), lead-author of one of the two companion papers in which this work is reported [1, 2]. "The warming caused by sunlight hitting the surfaces of asteroids and meteoroids leads to a gentle recoil effect as the heat is released," he added. "By analogy, if one were to shine light on a propeller over a long enough period, it would start spinning." Although this is an almost immeasurably weak force, its effect over millions of years is far from negligible. Astronomers believe the YORP effect may be responsible for spinning some asteroids up so fast that they break apart, perhaps leading to the formation of double asteroids. Others may be slowed down so that they take many days to complete a full turn. The YORP effect also plays an important role in changing the orbits of asteroids between Mars and Jupiter, including their delivery to planet-crossing orbits, such as those of near-Earth asteroids. Despite its importance, the effect has never been seen acting on a solar system body, until now. Using extensive optical and radar imaging from powerful Earth-based observatories, astronomers have directly observed the YORP effect in action on a small near-Earth asteroid, known as (54509) 2000 PH5. Shortly after its discovery in 2000, it was

    Imaginary play is often a child's best way of communicating affects, fantasies, and internal states. In play children are freer to express their forbidden and conflicted thoughts. Consequently, one of the best ways for the therapist to enter the child's world is to do so from within the displacement of the play process. For children who cannot play, the therapist's goal is to teach the child to use play as a means of communication and to create meaning. This article present clinical examples to illustrate how the author uses play in the clinical situation.

    Full Text Available Internet gaming disorder is currently listed in the DSM—not in order to diagnose such a disorder but to encourage research to investigate this phenomenon. Even whether it is still questionable if Internet Gaming Disorder exists and can be judged as a form of addiction, problematic game play is already very well researched to cause problems in daily life. Approaches trying to predict problematic tendencies in digital game play have mainly focused on playing time as a diagnostic criterion. However, motives to engage in digital game play and obsessive passion for game play have also been found to predict problematic game play but have not yet been investigated together. The present study aims at (1 analyzing if obsessive passion can be distinguished from problematic game play as separate concepts, and (2 testing motives of game play, passion, and playing time for their predictive values for problematic tendencies. We found (N = 99 males, Age: M = 22.80, SD = 3.81 that obsessive passion can be conceptually separated from problematic game play. In addition, the results suggest that compared to solely playing time immersion as playing motive and obsessive passion have added predictive value for problematic game play. The implications focus on broadening the criteria in order to diagnose problematic playing.

    2015-02-01

    Symbolic play and language are known to be highly interrelated, but the developmental process involved in this relationship is not clear. Three hypothetical paths were postulated to explore how play and language drive each other: (1) direct paths, whereby initiation of basic forms in symbolic action or babbling, will be directly related to all later emerging language and motor outputs; (2) an indirect interactive path, whereby basic forms in symbolic action will be associated with more complex forms in symbolic play, as well as with babbling, and babbling mediates the relationship between symbolic play and speech; and (3) a dual path, whereby basic forms in symbolic play will be associated with basic forms of language, and complex forms of symbolic play will be associated with complex forms of language. We micro-coded 288 symbolic vignettes gathered during a yearlong prospective bi-weekly examination (N=14; from 6 to 18 months of age). Results showed that the age of initiation of single-object symbolic play correlates strongly with the age of initiation of later-emerging symbolic and vocal outputs; its frequency at initiation is correlated with frequency at initiation of babbling, later-emerging speech, and multi-object play in initiation. Results support the notion that a single-object play relates to the development of other symbolic forms via a direct relationship and an indirect relationship, rather than a dual-path hypothesis.

  6. Playful biometrics: controversial technology through the lens of play.

    Science.gov (United States)

    Ellerbrok, Ariane

    2011-01-01

    This article considers the role of play in the context of technological emergence and expansion, particularly as it relates to recently emerging surveillance technologies. As a case study, I consider the trajectory of automated face recognition—a biometric technology of numerous applications, from its more controversial manifestations under the rubric of national security to a clearly emerging orientation toward play. This shift toward “playful” biometrics—or from a technology traditionally coded as “hard” to one now increasingly coded as “soft”—is critical insofar as it renders problematic the traditional modes of critique that have, up until this point, challenged the expansion of biometric systems into increasingly ubiquitous realms of everyday life. In response to this dynamic, I propose theorizing the expansion of face recognition specifically in relation to “play,” a step that allows us to broaden the critical space around newly emerging playful biometrics, as well as playful surveillance more generally. In addition, play may also have relevance for theorizing other forms of controversial technology, particularly given its potential role in processes of obfuscation, normalization, and marginalization.

    2008-04-01

    A 21-year-old man was found dead in a car. There were 9 empty bottles of 610HAP (a 440 g bottle of a liquid bath essence containing 160-195 g/kg sulfur) and 10 of Sunpole (a 500 mL bottle of a toilet bowl cleaner containing 9.5% HCl) in the car. The car doors were sealed with tape, and there was a strong smell of sulfur in and around the car. GC/MS analysis showed 0.66 microg/mL sulfide and 0.14 micromol/mL thiosulfate in the blood sample. The concentration of thiosulfate in the urine sample was normal. Police investigation concluded that the man killed himself by aspirating hydrogen sulfide that had been produced by mixing 610 HAP and Sunpole. To examine the amount of hydrogen sulfide produced, small portions of these liquids were mixed in a 560-mL volume flask. The results showed that 0.1 mL of each liquid produced 4,950 ppm of hydrogen sulfide, and 0.2 mL of each produced 10,800 ppm. According to these results, if the cabin volume is assumed to be 3,300 L, mixing 120 mL of each liquid produces a lethal level of hydrogen sulfide, i.e., 1,000 ppm. This was a rare suicide case, and it revealed the hazards of mixing of liquid bath essences containing sulfur and toilet bowl cleaners containing hydrochloric acid.

    The aim of this article is to present a formal definition of the aspect of play generally known as ‘make-believe’. ‘Make-believe’ is defined in relation to theory of place and Dasein’s being- in-the-world as presented by Martin Heidegger in Being and time. From this point of view ‘make-believe’ can...... be defined as a uniform and situational spatial dyad where being is doubled, characterized by the presence of the physically absent. I will apply this definition after a survey of central and influential aspects of the history of the theory of play to demonstrate its relevance for a formal definition of play....

  15. Adaptive Forgetting Factor Fictitious Play

    CERN Document Server

    Smyrnakis, Michalis

    2011-01-01

    It is now well known that decentralised optimisation can be formulated as a potential game, and game-theoretical learning algorithms can be used to find an optimum. One of the most common learning techniques in game theory is fictitious play. However fictitious play is founded on an implicit assumption that opponents' strategies are stationary. We present a novel variation of fictitious play that allows the use of a more realistic model of opponent strategy. It uses a heuristic approach, from the online streaming data literature, to adaptively update the weights assigned to recently observed actions. We compare the results of the proposed algorithm with those of stochastic and geometric fictitious play in a simple strategic form game, a vehicle target assignment game and a disaster management problem. In all the tests the rate of convergence of the proposed algorithm was similar or better than the variations of fictitious play we compared it with. The new algorithm therefore improves the performance of game-t...

[Method] The lotus variety Hongxia was chosen as the ex-perimental material. Two treatments, hydroponics and soil culture were set to mea-sure their photosynthetic indices, chlorophyl content and root vigor, and to observe their leaf tissue structure and stomatal characteristics. [Result] The findings indicated that there are no differences in the leaf physiological indices between bowl lotus un-der hydroponics and soil culture, while the leaf stomata of hydroponic bowl lotus is bigger and its amount is larger than that of soil-culture bowl lotus. At the same time, the ratio of the palisade tissue thickness to spongy tissue thickness is smal , and its leaf tissue structure is loose. The root vigor of hydroponic bowl lotus reached its summit earlier, then began to drop. Whereas, the root activity of soil-cul-ture lotus sustained increasing, with vigorous growth. [Conclusion] Therefore, it indi-cated that hydroponic bowl lotus can adapt to the aquatic-culture environment wel and quickly, meanwhile, it also enters into its aging period quickly and its growth cycle gets shorter.

    Understanding concepts of molecular mechanisms of drug action involves sequential visualization of physiological processes and drug effects, a task that can be difficult at an undergraduate level. Role-play is a teaching-learning methodology whereby active participation of students as well as clear visualization of the phenomenon is used to convey complex physiological concepts. However, its use in teaching drug action, a process that demands understanding of a second level of complexity over the physiological process, has not been investigated. We hypothesized that role-play can be an effective and well accepted method for teaching molecular pharmacology. In an observational study, students were guided to perform a role-play on a selected topic involving drug activity. Students' gain in knowledge was assessed comparing validated pre- and post-test questionnaires as well as class average normalized gain. The acceptance of role-play among undergraduate medical students was evaluated by Likert scale analysis and thematic analysis of their open-ended written responses.

  3. For the Phenomenology of Play

    Directory of Open Access Journals (Sweden)

    Roberto Farné

    2016-10-01

    Full Text Available The success of phenomenology in contemporary culture is due above all to the new approach to knowledge that has been proposed, breaking with the traditional objectivism of scientific knowledge and placing the “phenomenon” at the centre of the relationship between the subject and the world. Everyday reality, the language of concrete things, have become fully-fledged targets of philosophical thought. While Eugen Fink, student of Husserl, elects the phenomenon of play as the “symbol of the world”, the original interpretation of man’s relation to the world, in Italy Piero Bertolini redefines the scientific basis of pedagogy according to phenomenological categories and places play among the fundamental fields of experience of education. On one hand overcoming the traditional educational instrumentalisation of play, on the other its sterile reduction to a consumer experience, Bertolini brings play back to its authentic dimension in which risk, error, adventure are constituent parts, the “active ingredients” of his pedagogy.

    Directory of Open Access Journals (Sweden)

    Anne Greve

    2013-10-01

    Full Text Available There is a concern that children’s right to play is restricted as a result of the governments’ narrow focus on school preparatory activities and learning. Play and learning are rights embodied in the United Nations convention on the rights of the child. This article discusses how play and learning are organized in the everyday life of a Norwegian toddler group. Critical voices claim that there is not enough structure and that there should be more teaching and mapping to facilitate early intervention in Norwegian kindergartens. The article suggests that the critics’ claim can be countered by asking if there are too few teachers with adequate education and too large groups of children.

    In mix-game which is an extension of minority game, there are two groups of agents; group1 plays the majority game, but the group2 plays the minority game. This paper studies the change of the average winnings of agents and volatilities vs. the change of mixture of agents in mix-game model. It finds that the correlations between the average winnings of agents and the mean of local volatilities are different with different combinations of agent memory length when the proportion of agents in group 1 increases. This study result suggests that memory length of agents in group1 be smaller than that of agent in group2 when mix-game model is used to simulate the financial markets.

    2013-12-01

    Full Text Available In two studies, we examined the effect of different degrees of attraction reciprocation on ratings of attraction toward a potential romantic partner. Undergraduate college student participants imagined a potential romantic partner who reciprocated a low (reciprocating attraction one day a week, moderate (reciprocating attraction three days a week, high (reciprocating attraction five days a week, or unspecified degree of attraction (no mention of reciprocation. Participants then rated their degree of attraction toward the potential partner. The results of Study 1 provided only partial support for Brehm’s emotion intensity theory. However, after revising the high reciprocation condition vignette in Study 2, supporting Brehm’s emotion intensity theory, results show that a potential partners’ display of reciprocation of attraction acted as a deterrent to participants’ intensity of experienced attraction to the potential partner. The results support the notion that playing moderately hard to get elicits more intense feelings of attraction from potential suitors than playing too easy or too hard to get. Discussion of previous research examining playing hard to get is also re-examined through an emotion intensity theory theoretical lens.

From 1920 Kelemina was professor of Germanic philology and between 1920 and 1957 he was also the Chair of the Deparment ofGermanic Languages and Literatures at the Faculty of Arts of this university. The major part of Kelemina's research was devoted to German and Austrian literatures,  German  philology, German-Slovene cultural relations, and literary theory; his work in these fields has already been discussed  by severa! Slovene scholars. However, in the first two decades of the twentieth century Kelemina also wrote severa! book reviews of Slovene and Croatian translations of Shakespeare's plays as well as three introductory essays to Slovene translations  of Shakespeare's plays.

    Porcelain is one of China’s greatest achievernents. It appeared during the Eastern Han Dynasty (25-220) and developed into three types of blue porcelain, white porcelain and colored porcelain between the Tang and Song dynasties. From the time of the Ming Dynasty (1368-1644), porcelain-making evolved, glazes and colors improved and porcelain was sold overseas. The quaint shapes and colorfully deslgned porcelain of the Ming Dynasty showed the appeal of folklife, but it was mainly used in the palace. Shown here are some pieces decorated with children at play. From these artifacts we can get an idea of the hairstyles, dress and architecture of that time.

    Science.gov (United States)

    Leader, Carol

    2015-11-01

    The writer offers a combined experience in analysis and the performing arts to explore uncanny aspects of the unconscious subtext of the patient's inner drama; subtext which can remain hidden from view in supervision. Freud and Jung's understanding of uncanny experience is considered together with a painting from medieval alchemy and Matte Blanco's conceptions concerning the symmetrical nature of unconscious process. Theatre and the work of the theatre director and actor in approaching the multidimensional aspects of a play are then introduced. Finally clinical case material from group supervision demonstrates how the 'theatre of therapy' and the work of the supervisory couple and group promote the emergence of a more authentic conscious asymmetrical response to the patient's 'script' that can break the 'spell' of the transference/countertransference relationship. This in turn brings meaning to the underlying and implicit 'stage directions' that the patient has been unconsciously communicating. © 2015, The Society of Analytical Psychology.

  17. Playing Games with Quantum Mechanics

    CERN Document Server

    Phoenix, Simon J D

    2012-01-01

    We present a perspective on quantum games that focuses on the physical aspects of the quantities that are used to implement a game. If a game is to be played, it has to be played with objects and actions that have some physical existence. We call such games playable. By focusing on the notion of playability for games we can more clearly see the distinction between classical and quantum games and tackle the thorny issue of what it means to quantize a game. The approach we take can more properly be thought of as gaming the quantum rather than quantizing a game and we find that in this perspective we can think of a complete quantum game, for a given set of preferences, as representing a single family of quantum games with many different playable versions. The versions of Quantum Prisoners Dilemma presented in the literature can therefore be thought of specific instances of the single family of Quantum Prisoner's Dilemma with respect to a particular measurement. The conditions for equilibrium are given for playab...

    Play is the primary occupation of childhood and provides a potentially powerful means of assessing and treating children with autistic disorder. This study utilized a cross-sectional comparison design to investigate the nature of play engagement in children with AD (n = 24), relative to typically developing children (n = 34) matched for chronological age. Play behaviours were recorded in a clinical play environment. Videotapes comprising 15 minutes of the children's spontaneous play behaviour were analysed using time-interval analysis. The particular play behaviours observed and play objects used were coded. Differences in play behaviours (p motivation.

    Dexterous use of the hand represents a sophisticated sensorimotor function. In behaviors such as playing the piano, it can involve strong temporal and spatial constraints. The purpose of this study was to determine fundamental patterns of covariation of motion across joints and digits of the human hand. Joint motion was recorded while 5 expert pianists played 30 excerpts from musical pieces, which featured ∼50 different tone sequences and fingering. Principal component analysis and cluster analysis using an expectation-maximization algorithm revealed that joint velocities could be categorized into several patterns, which help to simplify the description of the movements of the multiple degrees of freedom of the hand. For the thumb keystroke, two distinct patterns of joint movement covariation emerged and they depended on the spatiotemporal patterns of the task. For example, the thumb-under maneuver was clearly separated into two clusters based on the direction of hand translation along the keyboard. While the pattern of the thumb joint velocities differed between these clusters, the motions at the metacarpo-phalangeal and proximal-phalangeal joints of the four fingers were more consistent. For a keystroke executed with one of the fingers, there were three distinct patterns of joint rotations, across which motion at the striking finger was fairly consistent, but motion of the other fingers was more variable. Furthermore, the amount of movement spillover of the striking finger to the adjacent fingers was small irrespective of the finger used for the keystroke. These findings describe an unparalleled amount of independent motion of the fingers.

    2015-09-01

    The literature has seen a surge in research on the mental health impacts of technologies such as Facebook, video games, and massively-multiplayer online role-playing games such as World of Warcraft, but little is known regarding the mental health impact of non-video role-playing games, such as Dungeons & Dragons. The present study examines how psychiatrists' perceive role-playing games and whether they play them. Psychiatrists at a tertiary care centre in Canada completed a questionnaire assessing history of playing role-playing games and whether they associate them with psychopathology. Forty-eight psychiatrists responded. Twenty-three percent have played a role-playing game over their lifetimes. Twenty-two percent believed there was an association between psychopathology and role-playing games. A majority of psychiatrists who responded do not associate role-playing games with psychopathology. Implications for clinical practice and future research are discussed.

    Full Text Available Clarinettists close and open multiple tone holes to alter the pitch of the tones. Their fingering technique must be fast, precise, and coordinated with the tongue articulation. In this empirical study, finger force profiles and tongue techniques of clarinet students (N = 17 and professional clarinettists (N = 6 were investigated under controlled performance conditions. First, in an expressive-performance task, eight selected excerpts from the first Weber Concerto were performed. These excerpts were chosen to fit in a 2 x 2 x 2 design (register: low--high; tempo: slow--fast, dynamics: soft--loud. There was an additional condition controlled by the experimenter, which determined the expression levels (low--high of the performers. Second, a technical-exercise task, an isochronous 23-tone melody was designed that required different effectors to produce the sequence (finger-only, tongue-only, combined tongue-finger actions. The melody was performed in three tempo conditions (slow, medium, fast in a synchronization-continuation paradigm. Participants played on a sensor-equipped Viennese clarinet, which tracked finger forces and reed oscillations simultaneously. From the data, average finger force (Fmean and peak force (Fmax were calculated. The overall finger forces were low (Fmean = 1.17 N, Fmax = 3.05 N compared to those on other musical instruments (e.g. guitar.

    In this paper we report a qualitative study based on the constant comparative method to initiate the systematic study of forms of vitality play. This is an unnoticed non-figurative play frame linked to early social play and temporal arts in which child and adult elaborate the dynamics of their own movements and sounds in a repetition-variation form. In the introduction we present the theoretical underpinnings and the sporadic observations we have done in previous studies. Then, by the iterative observations of the recorded material of a longitudinal case study on play during the third year of life, we generated the general category of forms of vitality play and four subcategories of display modes of forms of vitality play (improvised forms of vitality play, ritualized forms of vitality play, forms of vitality play combined with pretend play, and forms of vitality play combined with role playing) which are illustrated with descriptive narratives. We discuss the properties of the developed categories, the limits of the present study, and the need to continue systematizing the research on this playful activity.

    2016-07-01

    Crop fraction is the ratio of crop occupying a unit area in ground pixel, is very important for monitoring crop growth. One of the most important variables in crop growth monitoring is the fraction of available solar radiation intercepted by foliage. Late blight of potato (Solanum tuberosum), caused by the oomycete pathogen Phytophthora infestans, is considered to be the most destructive crop diseases of potato worldwide. Under favourable climatic conditions, and without intervention (i.e. fungicide sprays), the disease can destroy potato crop within few weeks. Therefore it is important to evaluate the crop fraction for monitoring the healthy and late blight affected potato crops. This study was conducted in potato bowl of West Bengal, which consists of districts of Hooghly, Howrah, Burdwan, Bankuara, and Paschim Medinipur. In this study different crop fraction estimation method like linear spectral un-mixing, Normalized difference vegetation index (NDVI) based DPM model (Zhang et al. 2013), Ratio vegetation index based DPM model, improved Pixel Dichotomy Model (Li et al. 2014) ware evaluated using multi-temporal IRS AWiFs data in two successive potato growing season of 2012-13 and 2013-14 over the study area and compared with measured crop fraction. The comparative study based on measured healthy and late blight affected potato crop fraction showed that improved Pixel Dichotomy Model maintain the high coefficient of determination (R2= 0.835) with low root mean square error (RMSE=0.21) whereas the correlation values of NDVI based DPM model and RVI based DPM model is 0.763 and 0.694 respectively. The changing pattern of crop fraction profile of late blight affected potato crop was studied in respect of healthy potato crop fraction which was extracted from the 269 GPS points of potato field. It showed that the healthy potato crop fraction profile maintained the normal phenological trend whereas the late blight affected potato crop fraction profile suddenly fallen

    Full Text Available How can we design intelligent play environments for open-ended play that support richness in play? Rich play can be described as ongoing play that changes over time in character, form and nature. This paper elaborates on our initial insights on how rules and goals develop from interaction opportunities of the system, based on two pilot studies with an interactive play environment for open-ended play. Furthermore we will discuss the roles of feedback and adaptation mechanisms in the environment. Those system properties will change the interaction opportunities to match with the current situation in the play environment and to support richness in play.

    2015-04-13

    We chemically integrated mesoporous silica nanoparticles (MSNs) and macroporous bowl-like polylactic acid (pBPLA) matrix, for noninvasive electrostatic loading and long-term controlled doxorubicin (DOX) release, to prepare a hierarchical porous bowl-like pBPLA@MSNs-COOH composite with a nonspherical and hierarchical porous structure. Strong electrostatic interaction with DOX rendered excellent encapsulation efficiency (up to 90.14%) to the composite. DOX release showed pH-dominated drug release kinetics; thus, maintaining a weak acidic pH (e.g., 5.0) triggered sustained release, suggesting the composite's great potential for long-term therapeutic approaches. In-vitro cell viability assays further confirmed that the composite was biocompatible and that the loaded drugs were pharmacologically active, exhibiting dosage-dependent cytotoxicity. Additionally, a wound-healing assay revealed the composite's intrinsic ability to inhibit cell migration. Moreover, pH- and time-dependent leaching of the integrated MSNs due to pBPLA matrix degradation allow us to infer that the leached (and drug loaded) MSNs may be engulfed by cancer cells contributing to a second wave of DOX-mediated cytotoxicity following pH-triggered DOX release.

  8. Playful expressions in one-year-old chimpanzee infants in social and solitary play contexts

    Directory of Open Access Journals (Sweden)

    Kirsty Mhairi Ross

    2014-07-01

    Full Text Available Knowledge of the context and development of playful expressions in chimpanzees is limited because research has tended to focus on social play, on older subjects, and on the communicative signaling function of expressions. Here we explore the rate of playful facial and body expressions in solitary and social play, changes from 12- to 15-months of age, and the extent to which social partners match expressions, which may illuminate a route through which context influences expression. Naturalistic observations of seven chimpanzee infants (Pan troglodytes were conducted at Chester Zoo, UK (n = 4, and Primate Research Institute, Japan (n = 3, and at two ages, 12 months and 15 months. No group or age differences were found in the rate of infant playful expressions. However, modalities of playful expression varied with type of play: in social play, the rate of play faces was high, whereas in solitary play, the rate of body expressions was high. Among the most frequent types of play, mild contact social play had the highest rates of play faces and multi-modal expressions (often play faces with hitting. Social partners matched both infant play faces and infant body expressions, but play faces were matched at a significantly higher rate that increased with age. Matched expression rates were highest when playing with peers despite infant expressiveness being highest when playing with older chimpanzees. Given that playful expressions emerge early in life and continue to occur in solitary contexts through the second year of life, we suggest that the play face and certain body behaviors are emotional expressions of joy, and that such expressions develop additional social functions through interactions with peers and older social partners.

The TViews table is an interactive tabletop media platform that can track the location of multiple tagged objects in real-time as they are moved around its surface, providing a simultaneous and coincident graphical display. In this paper we present the implementation of the first version of TTRPG, with a content set based on the traditional Dungeons & Dragons rule-set. We also discuss the results of a user study that used TTRPG to explore the possible social context of digital tabletop role-playing games.

  10. Forms of vitality play and symbolic play during the third year of life.

    Science.gov (United States)

    Español, Silvia; Bordoni, Mariana; Martínez, Mauricio; Camarasa, Rosario; Carretero, Soledad

    2015-08-01

    This article focuses on the development of forms of vitality play, a recently described type of play, and links it to the development of symbolic play, one of the most studied types of play in developmental psychology. Two adult-infant dyads were videotaped longitudinally during in-house free play meetings every 15 days during the third year of life. Convergence technique was applied in order to accelerate the longitudinal study. A total of 17h 48min were registered in 28 sessions. An observational code with categories of forms of vitality play (a non-figurative play frame in which child and adult play together with the dynamics of their own movements and sounds in a repetition-variation form), symbolic play, and categories of combined patterns of both types of play was applied. The rate of each play was calculated for different age periods. Forms of vitality play is present at a constant rate during the third year of life. Symbolic play flourishes during this period. Combined play patterns are not the most frequent but are present from the beginning to the end of the third year. We suggest that FoVP favours intimate and intersubjective experiences essential to the understanding and the development of the interpersonal world; that it can be thought of as a good runway for the development of symbolic play; and that it prepares the child to participate in the temporal arts that belong to his culture.

    Full Text Available Unlike the market slowdown of industrial robots, service & entertainment robots have been highly regarded by most robotics reseach and market research agencies. In this study we developed a music playing robot (which can also work as a service robot for public performance. The research is mainly focused on the mechanical and electrical control of piano-playing robot, the exploration of correlations among music theory, rhythm and piano keys, and eventually the research on playing skill of keyboard instrument. The piano-playing robot is capable of control linear motor, servo-motor and pneumatic devices in accordance with the notes and rhythm in order to drive the mechanical structure to proper positions for pressing the keys and generating music. The devices used for this robot are mainly crucial components produced by HIWIN Technology Corp. The design of robotic hand is based on the direction of anthropomorphic hand such that five fingers will be used for playing piano. The finger actuations include actions of finger rotation, finger pressing, and finger lifting; time required for these 3 stages must meet the requirement of rhythm. The purpose of entertainment robot can be achieved by playing electric piano with robotic hand, and we hope this research can contribute to the development of domestic entertainment music playing robots.

  15. Playing for health? Revisiting health promotion to examine the emerging public health position on children's play.

    Science.gov (United States)

    Alexander, Stephanie A; Frohlich, Katherine L; Fusco, Caroline

    2014-03-01

    Concerns over dwindling play opportunities for children have recently become a preoccupation for health promotion in western industrialized countries. The emerging discussions of play seem to be shaped by the urgency to address the children's obesity epidemic and by societal concerns around risk. Accordingly, the promotion of play from within the field appears to have adopted the following principles: (i) particular forms of play are critical for increasing children's levels of physical activity; and (ii) play should be limited to activities that are not risky. In this article, we argue that these emerging principles may begin to re-shape children's play: play is predominantly instrumentalized as a means to promote children's physical health, which may result in a reduction of possibilities for children to play freely and a restriction of the kinds of play designated as appropriate for physical health. We argue that within this context some of the social and emotional elements of health and well-being that children gain through diverse forms of playing are neglected. This has implications for health promotion because it suggests a narrowing of the conception of health that was originally advocated for within the field. Additionally, this reveals a curious paradox; despite the urgency to promote physical activity through play, this position may limit the range of opportunities for children to freely engage in play, in effect reducing their activity levels. We propose an example that promotes play for children and better aligns with the conception of health as outlined in the Ottawa Charter.

    Science.gov (United States)

    Lyytinen, P

    1991-01-01

    The developmental trends in pretend play were investigated in children 2-6 years of age (18 in each of five age groups) by examining changes in pretend action and speech separately. Play behaviour was assessed by using a selected set of Duplo Lego toys. Interest focused on occurrence of decentration, decontextualization and integration at different age levels. The proportions of decentred and decontextualized acts, action integrations and play themes, increased linearly with age. Changes in substitutive and inventive actions were, however, more minor than expected. Single-scheme combinations did not reveal any essential aspect of the development of children's symbolic competence. In this sense, multischeme combinations were more important in revealing the children's way of organizing toy material. Linear age trends were not found for language measures. The use of decentred utterances, language integrations and linguistically expressed themes were individual-specific rather than age-related. Issues for studying pretend play in language-impaired groups are also suggested.

  18. Playing violent video games increases intergroup bias.

    Science.gov (United States)

    Greitemeyer, Tobias

    2014-01-01

    Previous research has shown how, why, and for whom violent video game play is related to aggression and aggression-related variables. In contrast, less is known about whether some individuals are more likely than others to be the target of increased aggression after violent video game play. The present research examined the idea that the effects of violent video game play are stronger when the target is a member of an outgroup rather than an ingroup. In fact, a correlational study revealed that violent video game exposure was positively related to ethnocentrism. This relation remained significant when controlling for trait aggression. Providing causal evidence, an experimental study showed that playing a violent video game increased aggressive behavior, and that this effect was more pronounced when the target was an outgroup rather than an ingroup member. Possible mediating mechanisms are discussed.

  7. Golden Jubilee Photos: Theorists at play

    CERN Multimedia

    2004-01-01

    Alvaro De Rújula and John Ellis, two of the best-known theorists at CERN, on stage for the 1983 Theory Division play. The stereotype of theoretical physicists has them with their heads in the clouds. But CERN theorists have turned this notion on its head with their annual satirical plays. The first, in 1978, poked fun at the conflict between two competing groups who wanted the chance to perform the second experiment with the then-new Super Proton Synchrotron (SPS). Theorist John Ellis, who has been involved with most of the plays over the years, says the theorists "came up with the idea of defusing the tension by having the play." Each year, they base the play on a theme or symbol that will resonate with people from any culture. This first play was loosely based on l'Escalade, Geneva's annual celebration of having repelled the Duke of Savoy's attack in 1602. In the 1980s they staged "CERN lake," inspired by the ballet "Swan Lake"-and by the problems in digging the Large Electron Positron (LEP) collider's tu...

    Full Text Available A diverse, cross-sectorial group of partners, stakeholders and researchers, collaborated to develop an evidence-informed Position Statement on active outdoor play for children aged 3–12 years. The Position Statement was created in response to practitioner, academic, legal, insurance and public debate, dialogue and disagreement on the relative benefits and harms of active (including risky outdoor play. The Position Statement development process was informed by two systematic reviews, a critical appraisal of the current literature and existing position statements, engagement of research experts (N = 9 and cross-sectorial individuals/organizations (N = 17, and an extensive stakeholder consultation process (N = 1908. More than 95% of the stakeholders consulted strongly agreed or somewhat agreed with the Position Statement; 14/17 participating individuals/organizations endorsed it; and over 1000 additional individuals and organizations requested their name be listed as a supporter. The final Position Statement on Active Outdoor Play states: “Access to active play in nature and outdoors—with its risks— is essential for healthy child development. We recommend increasing children’s opportunities for self-directed play outdoors in all settings—at home, at school, in child care, the community and nature.” The full Position Statement provides context for the statement, evidence supporting it, and a series of recommendations to increase active outdoor play opportunities to promote healthy child development.

    Playfulness has been referred to as a disposition that involves reframing a situation to amuse others and to make the situation more stimulating and enjoyable. It may serve to shift one's perspective when dealing with environmental threats. Despite all the benefits of playfulness towards psychological well-being, it remains a largely understudied subject in psychology, particularly in Chinese societies. Hence, this study examined the association between adult playfulness, humor styles, and subjective happiness among a sample of 166 university students in Hong Kong and 159 students in Guangzhou, who completed a self-administered questionnaire, including the Short Measure for Adult Playfulness, the Chinese Humor Styles Questionnaire, and the Subjective Happiness Scale. Results showed that adult playfulness was positively correlated with affiliative humor, self-enhancing humor, and subjective happiness in both Hong Kong and Guangzhou samples. By its implication, highly playful Chinese students preferred using affiliative and self-enhancing humor to amuse themselves and others. © The Author(s) 2016.

    This qualitative study investigated the personal experiences of children with cerebral palsy engaging in a virtual reality play intervention program. The study involved in-depth, focused interviews that were conducted with 19 participants aged 8-13 who had a diagnosis of cerebral palsy. A constant comparative inductive method of analysis was used, and several themes emerged. Findings were interpreted using the theory of flow, the theory of self-efficacy, and the model of playfulness in virtual reality computer interactions. The three themes uncovered in the data include (a) doing play, (b) it's my way that matters, and (c) how I see me. The sub-theme safety also emerged. Findings from this study showed that children with physical disabilities are often limited in their play experience compared to their peers without physical disabilities. Children perceived engagement in a virtual reality play intervention program as an enjoyable experience which increased their self-competence and self-efficacy. Participants experienced a sense of control and mastery over the virtual environment and were provided a safe way to explore and challenge their abilities. Participants perceived experiencing flow and reported perceived physical changes and increased social acceptance from both peers and family. These findings provide evidence that virtual reality continues to show promise as a pediatric rehabilitation play intervention tool.

  15. When play is a family business: adult play, hierarchy, and possible stress reduction in common marmosets.

    Science.gov (United States)

    Norscia, Ivan; Palagi, Elisabetta

    2011-04-01

    Easy to recognize but not easy to define, animal play is a baffling behavior because it has no obvious immediate benefits for the performers. However, the absence of immediate advantages, if true, would leave adult play (costly but maintained by evolution, spanning lemurs to Homo sapiens) unexplained. Although a commonly held view maintains that play is limited by stress, an emergent hypothesis states that play can regulate stress in the short term. Here we explored this hypothesis in a captive family group of New World monkeys, Callithrix jacchus (common marmoset). We observed six subjects and gathered data on aggressive, play, and scratching behavior via focal (6 h/individual) and all occurrences sampling (115 h). We found that play levels were highest during pre-feeding, the period of maximum anxiety due to the forthcoming competition over food. Scratching (the most reliable indicator of stress in primates) and play showed opposite trends along hierarchy, with dominants scratching more and playing less than subordinates. Finally, scratching decreased after play, whereas play appeared to be unrelated to previous scratching events, symptoms of a potential stressful state. In conclusion, both play timing and hierarchical distribution indicate that play limits stress, more than vice versa, at least in the short term.

  16. Time perspective as a predictor of massive multiplayer online role-playing game playing.

    Lukavska, Katerina

    2012-01-01

    This article focuses on the relationship between the time perspective (TP) personality trait and massive multiplayer online role-playing game (MMORPG) playing. We investigate the question of frequency of playing. The TP was measured with Zimbardo's TP Inventory (ZTPI), which includes five factors-past negative, past positive, present hedonistic, present fatalistic, and future. The study used data from 154 MMORPG players. We demonstrated that TP partially explained differences within a group of players with respect to the frequency of playing. Significant positive correlations were found between present factors and the amount of time spent playing MMORPGs, and significant negative correlation was found between the future factor and the time spent playing MMORPGs. Our study also revealed the influence of future-present balance on playing time. Players who scored lower in future-present balance variables (their present score was relatively high compared with their future score) reported higher values in playing time. In contrast to referential studies on TP and drug abuse and gambling, present fatalistic TP was demonstrated to be a stronger predictor of extensive playing than present hedonistic TP, which opened the question of motivation for playing. The advantage of our study compared with other personality-based studies lies in the fact that TP is a stable but malleable personality trait with a direct link to playing behavior. Therefore, TP is a promising conceptual resource for excessive playing therapy.

  5. A Staged Reading of the Play: Reykjavik

    Science.gov (United States)

    2017-01-01

    Reykjavik is the capital of Iceland, an island country located about 500 miles northwest of Scotland in the North Atlantic. In 1986 Mikhail Gorbachev, the Chairman of the Politburo of the Soviet Union and General Secretary of the Soviet Communist Party, invited Ronald Reagan, the President of the United States, to meet with him. The play Reykjavik is a dramatic reconstruction of the two-day summit meeting during which the world leaders almost reached agreement on the total abolition of their countries' nuclear weapons. The play uses the actual transcripts of the Reykjavik meeting as well as the memoirs of both Reagan and Gorbachev. Join us for a dramatic staged reading of Reykjavik and find out how close the two superpowers, the Soviet Union and the United States, came to eliminating their nuclear weapons. He playwright is Richard Rhodes, the Pulitzer Prize-winning author of 24 books. He has written his first play, and it spins off of his research into the history of nuclear weapons. The staged reading is performed by the Washington based Tonic Theater Company: http://www.tonictheater.org/[tonictheater.org]. After the performance, the play director and actors as well as experts on nuclear disarmament will be available for a talk-back discussion of the play with the audience. Produced by Brian Schwartz, Brooklyn College and the Graduate Center of the City University of New York and Gregory Mack of the APS Washington office.

  6. Bluetooth as a Playful Public Art Interface

    Science.gov (United States)

    Stukoff, Maria N.

    This chapter investigates how the application of emergent communication technologies assisted in the design of playful art experience in a public place. Every Passing Moment (EPM), was a mobile public artwork that tracked and recorded any discoverable Bluetooth device to automatically seed a flower in a virtual garden projected onto an urban screen. The EPM was the first public art work to run blu_box, a custom-designed Bluetooth system for mobile telephony. The aim of blu_box was to build a system that supported playful interactions between the public and an urban screen, openly accessible to anyone with a Bluetooth-enabled mobile phone. This participatory engagement was observed in EPM on three levels, namely; unconscious, conscious, and dynamic play. Furthermore, this chapter highlights how sound and face-to-face communication proved imperative in the play dynamics of EPM. In conclusion, this chapter proposes ways in which the use of emergent communication technologies in public places, especially when interfaced with urban screening platforms, can construct playful city spaces for the public at large.

    2002-01-01

    This article introduces the results of scientific research performed in 1995-1997 in Kaunas primary school with 1st and 2nd grade children exhibiting behavioral disorders. Play therapy, a quite novel method in the country, seeks better improvement and an achievement of a better relationship for disadvantaged children in educational process. Play group counseling, or play media counseling, is shown as an important method in working with early primary grade children, especially those who present behavioral problems in the classroom. Another important aspect of group play therapy is the concentrated relationship with the counselor. Primary school children, especially those who are disadvantaged respond more to warmth than to praise for being right and doing well. Data analysis allow us to assume that behavioral difficulties of primary school children are connected with a low rate of self-esteem and dissatisfaction with their vital activities. Main conclusions to correspond with hypothesis held for the research are: a) children exhibiting behavioral problems are less active in educational process; b) by means of systematic use of play group counseling method in school, problematic children are able to solve their difficulties and to optimize their academic improvement; c) there is a complementary relationship between child's self-esteem and his/her satisfaction with his/her vital activity.

    2015-07-01

    Full Text Available During children's symbolic play many cognitive, emotional and social processes take place. A child develops her potential through symbolic play, and creativity is one such potential. Our research focused on investigating the relationship between creativity in early childhood and physical representation of play material in the context of symbolic play. 59 children were included in the study, aged from five to six years. We assessed their creativity before and after ten play-sessions using the Test for Creative Thinking TCT-DP. Each child played individually with one of six types of play material that varied with respect to three characteristics: structure, realism, and complexity. We hypothesized that creativity would increase for all types of play material but that it would not increase evenly across play materials. Due to statistically insignificant differences in creativity measures over time, we could not validate these hypotheses. We did however find a small increase in creativity for a group that played with low-structured, low-realism and low-complexity play material. This result is consistent with other similar research in the field.

    2000-01-01

    It is well established that certain aspects of play in young children are related to their emerging linguistic skills. The present study examined the relationships between functional play, symbolic play, non-verbal ability, and expressive and receptive language in normally developing children aged between 1 and 6 years using standardized assessment procedures, including a recently developed Test of Pretend Play (ToPP). When effects of chronological age were partialled out, symbolic play remained significantly correlated with both expressive and receptive language, but not with functional play or non-verbal ability; and functional play was only correlated significantly with expressive language. It is concluded that ToPP will provide practitioners with a useful way of assessing symbolic ability in children between the ages of 1 and 6 years, and will contribute to the assessment and diagnosis of a number of communication difficulties, and have implications for intervention.

  11. MAJOR PLAYS IN UTAH AND VICINITY

    Energy Technology Data Exchange (ETDEWEB)

    2003-11-01

    Utah oil fields have produced over 1.2 billion barrels (191 million m{sup 3}). However, the 13.7 million barrels (2.2 million m{sup 3}) of production in 2002 was the lowest level in over 40 years and continued the steady decline that began in the mid-1980s. The Utah Geological Survey believes this trend can be reversed by providing play portfolios for the major oil-producing provinces (Paradox Basin, Uinta Basin, and thrust belt) in Utah and adjacent areas in Colorado and Wyoming. Oil plays are geographic areas with petroleum potential caused by favorable combinations of source rock, migration paths, reservoir rock characteristics, and other factors. The play portfolios will include: descriptions and maps of the major oil plays by reservoir; production and reservoir data; case-study field evaluations; summaries of the state-of-the-art drilling, completion, and secondary/tertiary techniques for each play; locations of major oil pipelines; descriptions of reservoir outcrop analogs; and identification and discussion of land-use constraints. All play maps, reports, databases, and so forth, produced for the project will be published in interactive, menu-driven digital (web-based and compact disc) and hard-copy formats. This report covers research activities for the first quarter of the second project year (July 1 through September 30, 2003). This work included (1) describing the Conventional Southern Uinta Basin Play, subplays, and outcrop reservoir analogs of the Uinta Green River Conventional Oil and Gas Assessment Unit (Eocene Green River Formation), and (2) technology transfer activities. The Conventional Oil and Gas Assessment Unit can be divided into plays having a dominantly southern sediment source (Conventional Southern Uinta Basin Play) and plays having a dominantly northern sediment source (Conventional Northern Uinta Basin Play). The Conventional Southern Uinta Basin Play is divided into six subplays: (1) conventional Uteland Butte interval, (2) conventional

  12. Magical arts: the poetics of play.

    Science.gov (United States)

    Jacobus, Mary

    2005-01-01

    The paper argues that links between play and magic in British Object Relations point to the persistence of aesthetic concerns within psychoanalysis. Magical thinking is present in British Object Relations psychoanalysis from its beginnings in Klein's play technique and early aesthetic writings, surfacing elsewhere in Susan Isaac's educational experiments and her theories of metaphor. Marion Milner's clinical account of the overlapping areas of illusion and symbol-formation in a boy's war-games link the primitive rituals of Frazer's "The Golden Bough" with her patient's creativity. In Winnicott's concept of the transitional object, the theory of play achieves its apotheosis as a diffusive theory of culture or "private madness," and as a paradigm for psychoanalysis itself. Tracing the non-positivistic, mystical, and poetical elements in British Object Relations underlines the extent to which aesthetics is not just entangled with psychoanalysis, but constitutive of it in its mid-twentieth century manifestations.

I will use examples of empirical data gathered during spring 2006 to demonstrate that play can function as a useful learning strategy, and also point out barriers...... strategy might lead to changes on three interrelated levels: the teaching material, the educational context (i.e. teaching style, use of the physical facilities and schools organisational structure) and the cultural-historical way schools function within Danish in society.......This paper presupposes the notion that there is potential for the integration of play into primary and secondary school activities, because it can stimulate and support the formal as well as informal learning that takes place in school. Digital technology could be a driver for this integration...

  14. MOVING EDUCATIONAL ROLE-PLAY BEYOND ENTERTAINMENT

    Directory of Open Access Journals (Sweden)

    Thomas Duus Henriksen

    2010-11-01

    Full Text Available Educational role-play has long proved an effective tool for consultants trying to develop the skills that employees are using for performing certain job functions. However, while educational role-play often is presented as an entertaining means for learning, such insistence on making learning games more gamish seems to have an inhibiting effect on designing and thinking games beyond mere skill acquisition. By emphasising the role-play based process as a conflictual negotiation between distinctive categories of knowledge, this paper presents the explorative application of knowledge, while framing the facilitation of reflective processes as the key for transcending knowledge from the game’s context to that of the participants. While pointing towards the compatibility issues between current conceptions of learning games and the facilitation of reflective processes, the paper emphasises the need for thinking the learning game as a part of a didactic design, rather than something beneficial in itself.

  18. Freud on play, games, and sports fanaticism.

    Holowchak, M Andrew

    2011-01-01

    Much has been written in the secondary literature on Freud's aggression-release perspective vis-à-vis competitive sports. Very little has been written, however, on Freud's own explicit contribution to play, games, and sport. That is likely the result of Freud's reluctance to take up them--especially from the gamesman's and sportsman's points of view. One can, however, tease out the development of Freud's thoughts on games, play, and sport through a careful examination of his corpus over time. In doing so, one finds an early view of play and games, where the drives behind those activities are self- and other-preservative, and a later view, where Freud introduces his death drive. The article ends with some notions on what Freud might have said on the fanaticism that accompanies competitive sport, had he expressly taken up the issue.

  19. Cracking Bank PINs by Playing Mastermind

    Focardi, Riccardo; Luccio, Flaminia L.

    The bank director was pretty upset noticing Joe, the system administrator, spending his spare time playing Mastermind, an old useless game of the 70ies. He had fought the instinct of telling him how to better spend his life, just limiting to look at him in disgust long enough to be certain to be noticed. No wonder when the next day the director fell on his chair astonished while reading, on the newspaper, about a huge digital fraud on the ATMs of his bank, with millions of Euros stolen by a team of hackers all around the world. The article mentioned how the hackers had 'played with the bank computers just like playing Mastermind', being able to disclose thousands of user PINs during the one-hour lunch break. That precise moment, a second before falling senseless, he understood the subtle smile on Joe's face the day before, while training at his preferred game, Mastermind.

  1. Playing Muller Games in a Hurry

    2010-06-01

    Full Text Available This work studies the following question: can plays in a Muller game be stopped after a finite number of moves and a winner be declared. A criterion to do this is sound if Player 0 wins an infinite-duration Muller game if and only if she wins the finite-duration version. A sound criterion is presented that stops a play after at most 3^n moves, where n is the size of the arena. This improves the bound (n!+1^n obtained by McNaughton and the bound n!+1 derived from a reduction to parity games.

    Live action role-playing games share a range of characteristics with massively multi-player online games (MMOGs). Because these games have existed for more than 20 years, players of these games have a substantial amount of experience in handling issues pertinent to MMOGs. Survey and review of live...... action role-playing games, whose participant count can be in the thousands, reveal that features such as size, theme, game master-to-player ratio, and others interact to form complex systems that require several different groups of control tools to manage. The way that these games are managed offers...

  6. On the significance of adult play: what does social play tell us about adult horse welfare?

    Science.gov (United States)

    Hausberger, Martine; Fureix, Carole; Bourjade, Marie; Wessel-Robert, Sabine; Richard-Yris, Marie-Annick

    2012-04-01

    Play remains a mystery and adult play even more so. More typical of young stages in healthy individuals, it occurs rarely at adult stages but then more often in captive/domestic animals, which can imply spatial, social and/or feeding deprivations or restrictions that are challenging to welfare, than in animals living in natural conditions. Here, we tested the hypothesis that adult play may reflect altered welfare states and chronic stress in horses, in which, as in several species, play rarely occurs at adult stages in natural conditions. We observed the behaviour (in particular, social play) of riding school horses during occasional outings in a paddock and measured several stress indicators when these horses were in their individual home boxes. Our results revealed that (1) the number of horses and rates of adult play appeared very high compared to field report data and (2) most stress indicators measured differed between `players' and `non-players', revealing that most `playful' animals were suffering from more chronic stress than `non-playful' horses. Frequency of play behaviour correlated with a score of chronic stress. This first discovery of a relationship between adult play and altered welfare opens new lines of research that certainly deserves comparative studies in a variety of species.

    A serious illness, a chronic medical condition or a hospital bed should not deny any child her/his basic right to play, a right essential for children's development and general wellbeing. In fact, it is in these frightening and anxious moments that play and the stimulus that it provides can help the most. This article will focus on the impacts and benefits of professional hospital clowning for the wellbeing and recovery process of ill and hospitalized children. Our experience has shown that through interactive play and humor, "clowndoctors" can create an enabling and supportive environment that facilitates children's adaptation to the hospital setting and improves their acceptance of medical procedures and staff. While moving from bedside to bedside, RED NOSES clowndoctors encourage children's active participation and support their natural instinct to play, fully including them in the interaction, if the children wish to do so. Therefore, clowndoctor performances offer ill children much needed stimulus, self-confidence and courage, elements fundamental to reducing their vulnerability. In this piece, a special emphasis will be put on the various approaches used by RED NOSES clowndoctors to bond and reach out to children suffering from different medical conditions.

  20. Compassionate Play in The Ludic Century

    Directory of Open Access Journals (Sweden)

    James Dyer

    2014-11-01

    Full Text Available In 2013 game designer Eric Zimmerman wrote a provocative manifesto entitled ‘Manifesto for a Ludic Century’ (2013a, in which Zimmerman declares the 21st Century’s dominant cultural form to be games. Consequently, Zimmerman proposes that the individual occupant of the century is therefore in a continuous state of game engagement. As such, this re-contextualisation of game space and play, indefinitely articulates the individual as a constant player and character, and thusly challenges the notions of selfhood. Importantly it should be noted, the state of a ludic century is explicitly assumed as a truth, however superficial it may appear. Accordingly, this paper is then afforded to be an extended hypothesis of the proposed ludic century, rather than a critical dissection and response to Zimmerman’s manifesto. This enables a hermeneutic framing of the questions: ‘What does it mean to live in a ludic century?’and ‘in what capacity may the self exist in the ludic century?’ These questions will attempt to distinguish play as an inherent cultural logic that extends beyond the limitations of explicit ‘gamification’ or instrumental play (Stenros et al., 2009; Zichermann, 2010. Concluding, it is claimed that the ludic century elicits a sustained delusion of self, as the player is confined to the designed game structure, which inhibits authentic engagement and interaction with environment and self. It is proposed that this evokes a form of suffering, the compassionate play within the ludic century.

    Most cases of sexual asphyxia are due to autoerotic activity. Asphyxia due to oronasal occlusion is mostly seen in very old or very young victims. Oronasal occlusion is also used in sadomasochistic sexual practices like "breath control play" or "erotic asphyxiation". If life saving time limitations of oronasal occlusion are not observed, conviction for homicide caused by negligence is possible.

    2014-01-01

    Video games are a ubiquitous part of almost all children's and adolescents' lives, with 97% playing for at least one hour per day in the United States. The vast majority of research by psychologists on the effects of "gaming" has been on its negative impact: the potential harm related to violence, addiction, and depression. We recognize the value of that research; however, we argue that a more balanced perspective is needed, one that considers not only the possible negative effects but also the benefits of playing these games. Considering these potential benefits is important, in part, because the nature of these games has changed dramatically in the last decade, becoming increasingly complex, diverse, realistic, and social in nature. A small but significant body of research has begun to emerge, mostly in the last five years, documenting these benefits. In this article, we summarize the research on the positive effects of playing video games, focusing on four main domains: cognitive, motivational, emotional, and social. By integrating insights from developmental, positive, and social psychology, as well as media psychology, we propose some candidate mechanisms by which playing video games may foster real-world psychosocial benefits. Our aim is to provide strong enough evidence and a theoretical rationale to inspire new programs of research on the largely unexplored mental health benefits of gaming. Finally, we end with a call to intervention researchers and practitioners to test the positive uses of video games, and we suggest several promising directions for doing so.

  6. Play Behavior in Wolves: Using the '50:50' Rule to Test for Egalitarian Play Styles.

    Directory of Open Access Journals (Sweden)

    Jennifer L Essler

    Full Text Available Social play is known as a cooperative interaction between individuals involving multiple mechanisms. However, the extent to which the equality of individuals' play styles affects the interaction has not been studied in many species. Dyadic play between wolf puppies, as well as between puppies and adults, was studied to investigate both self-handicapping and offensive behaviors to determine the extent to which wolves engage in play styles where one individual does not dominate the play. Our results did not support the hypothesized '50:50' rule, which suggests that more advantaged individuals should show higher rates of self-handicapping behaviors in order to facilitate play with others. Adult wolves performed significantly less self-handicapping behaviors than their puppy partners, and they performed significantly more offensive behaviors than their puppy partners. While the '50:50' rule was not supported at any time during our study period, dyads consisting of two puppies had significantly more equal play than dyads consisting of one puppy and one adult. These results suggest that wolf puppies are more likely to play on equal terms with similarly-aged play partners, while the dominance status of the partners dictates offensive and self-handicapping behaviors between animals of different ages.

  8. MAJOR OIL PLAYS IN UTAH AND VICINITY

    Energy Technology Data Exchange (ETDEWEB)

    Thomas C. Chidsey Jr; Craig D. Morgan; Roger L. Bon

    2003-07-01

    Utah oil fields have produced over 1.2 billion barrels (191 million m{sup 3}). However, the 13.7 million barrels (2.2 million m{sup 3}) of production in 2002 was the lowest level in over 40 years and continued the steady decline that began in the mid-1980s. The Utah Geological Survey believes this trend can be reversed by providing play portfolios for the major oil producing provinces (Paradox Basin, Uinta Basin, and thrust belt) in Utah and adjacent areas in Colorado and Wyoming. Oil plays are geographic areas with petroleum potential caused by favorable combinations of source rock, migration paths, reservoir rock characteristics, and other factors. The play portfolios will include: descriptions and maps of the major oil plays by reservoir; production and reservoir data; case-study field evaluations; summaries of the state-of-the-art drilling, completion, and secondary/tertiary techniques for each play; locations of major oil pipelines; descriptions of reservoir outcrop analogs; and identification and discussion of land use constraints. All play maps, reports, databases, and so forth, produced for the project will be published in interactive, menu-driven digital (web-based and compact disc) and hard-copy formats. This report covers research activities for the third quarter of the first project year (January 1 through March 31, 2003). This work included gathering field data and analyzing best practices in the eastern Uinta Basin, Utah, and the Colorado portion of the Paradox Basin. Best practices used in oil fields of the eastern Uinta Basin consist of conversion of all geophysical well logs into digital form, running small fracture treatments, fingerprinting oil samples from each producing zone, running spinner surveys biannually, mapping each producing zone, and drilling on 80-acre (32 ha) spacing. These practices ensure that induced fractures do not extend vertically out of the intended zone, determine the percentage each zone contributes to the overall

    The uniqueness of shale gas plays is contrasted with conventional oil and gas exploration. Based on our ten year history in shale gas exploration, a practical 17 point list of criteria to use for screening shale gas projects and ranking that encompasses geoscience, geochemistry, reservoir engineering, drilling, completions and production operations is developed and explained. Other considerations that will impact shale gas development are identified and discussed. Some key methodologies to incorporate in the evaluation process are also proposed. The outcome of this proposed screening process, if rigorously applied,should quickly identify the projects that have the most likely chance for success for recommendation to management. Examples from active shale gas plays in the United States are used to support these criteria and references to relevant recent publications and presentations are provided.

    Browser games--mostly persistent game worlds that can be used without client software and monetary cost with a Web browser--belong to the understudied digital game types, although they attract large player communities and motivate sustained play. The present work reports findings from an online survey of 8,203 players of a German strategy browser game ("Travian"). Results suggest that multiplayer browser games are enjoyed primarily because of the social relationships involved in game play and the specific time and flexibility characteristics ("easy-in, easy-out"). Competition, in contrast, seems to be less important for browser gamers than for users of other game types. Findings are discussed in terms of video game enjoyment and game addiction.

    Rorschach responses of three subjects were used to stimulate the type of role-playing popularized by Fritz Perls' Gestalt therapy. The standard Rorschachs were given first. Afterwards, each subject was presented with certain of his or her own images as a stimulus for the role-playing. The subjects consisted of a 19-year-old female with severe anxiety attacks, an 11-year-old lad diagnosed as having minimal cerebral dysfunction, and a 46-year-old man who had undergone two years of successful psychotherapy. It is proposed that the resulting data are valuable in expanding and clarifying the psychological meaning of the Rorschach images. Further, the procedure can be utilized, if desired, as a spur to therapeutic involvement.

    This paper presents a controversial approach to innovating educational role-play. It is argued that we should stop thinking games as an entertaining mean for facilitating participation, and instead try to see games as a content provider and feedback mechanism. A theoretical model is presented...... on how learning games can benefit from such thinking, allowing learning games to change focus from trivial drill-andpractice purposes, to facilitating advanced learning processes, such as reflection and change learning....
