This paper highlights the not-so-obvious but compelling reasons why the same supportive audiences that can help performers attain their highest potential also may increase performers' risk of choking under pressure. Drawing primarily from social psychology research and theory, we conclude that audience support magnifies performance pressure and induces performers to avoid failure rather than se...

Feeding development in infants is important not only for of the purpose of acquiring nutrition but also for developing the ability to intake liquids. Our previous study showed that the introduction of a straw was appropriate after an infant has acquired the ability to sip liquid from a spoon and/or cup. In this study, we investigated the effect of a bowlshaped spoon on liquid intake. The aim of...

One of the most ubiquitous and long-lasting recent changes to the surface of our planet is the accumulation and fragmentation of plastics. Within just a few decades since mass production of plastic products commenced in the 1950s, plastic debris has accumulated in terrestrial environments, in the open ocean, on shorelines of even the most remote islands and in the deep sea. Annual clean-up oper...

Circular drop manholes are widely implemented for steep catchments in urban drainage networks. Poor downstream hydraulic transition processes of a manhole system, i.e., the formation jump near outlet entrance, and sudden from free surface to pressurized flow with bursts air outflow pipe can severely constraint capacity water conveyance. In this paper, we defined four basic stages that indicate ...

BACKGROUND In Baby-Led Weaning (BLW), infants are offered 'finger' foods from the start of the complementary feeding period instead of being spoon-fed. Healthcare professionals have expressed concerns about adequacy of iron and energy intake, and about choking, for infants following Baby-Led Weaning. METHODS We developed a modified version of BLW, Baby-Led Introduction to SolidS (BLISS), to a...

Poor performance in pressure-filled situations, or "choking under pressure," has largely been explained by two different classes of theories. Distraction theories propose that choking occurs because attention needed to perform the task at hand is coopted by task-irrelevant thoughts and worries. Explicit monitoring theories claim essentially the opposite-that pressure prompts individuals to atte...

Prader-Willi Syndrome (PWS) is caused by a genetic imprinting abnormality resulting from the lack of expression of the paternal genes at 15q11-q13. Intellectual disability, low muscle tone, and life-threatening hyperphagia are hallmarks of the phenotype. The need for the Heimlich maneuver, death from choking, and pulmonary infection occur in a disproportionally high number of persons with PWS. ...

High availability in network services is crucial for effective largescale distributed computing. While distributed denial-of-service (DDoS) attacks through massive packet flooding have baffled researchers for years, a new type of even more detrimental attack—shrew attacks (periodic intensive packet bursts with low average rate)—has recently been identified. Shrew attacks can significantly degra...

A 1-D analysis for the prediction of ejector performance at critical-mode operation is carried out in the present study. Constant-pressure mixing is assumed to occur inside the constant-area section of the ejector and the entrained flow at choking condition is analyzed. We also carried out an experiment using 11 ejectors and R141b as the working fluid to verify the analytical results. The test ...
