Pentaquarks: review of the experimental evidence

Pentaquarks, namely baryons made by 4 quarks and one antiquark have been predicted and searched for since several decades without success. Theoretical and experimental advances in the last 2 years led to the observation of a number of pentaquark candidates. We review the experimental evidence for pentaquarks as well as their non-observations by some experiments, and discuss to which extend these sometimes contradicting informations may lead to a consistent picture.Comment: Contribution to the International Conference on 'Strangeness in Quark Matter', 15-21 Sept. 2004, Cape Tawn, South Afric

Process design for optimizing text-based communication between physicians and nurses

Background and Aim Communication between physicians and nurses is a cornerstone of high-quality inpatient care. HIPAA-compliant text-based methods offer an alternative to the pager for communication between nurses and physicians. While messaging is popular in the personal setting, text-based professional communication in hospitals may increase the number of messages without improving coordination between care providers. (1) In addition, urgent messages that are more appropriately calls could be missed by the physician, leading to a delay in action. Other institutions use triage systems to communicate a question or clinical change by the urgency of expected physician response, which have attempted to mitigate this issue. (2) We aimed to improve bidirectional communication between housestaff and nursing with a communication process developed jointly by both parties using QI methods such as stakeholder analysis and a structured Work-Out session to brainstorm solutions

Changing digital media environments and youth audiovisual productions: A comparison of two collaborative research experiences with south Madrid adolescents

SAGE: David Poveda, Marta Morgade, Changing Digital Media Environments and Youth Audiovisual Productions: A Comparison of Two Collaborative Research Experiences with South Madrid Adolescents, Young 26.4 (2018): 34-55 Copyright © 2018SAGE. Reprinted by permission of SAGE PublicationsThis article compares two studies conducted in Madrid in a seven–eight years span in which secondary school students (14–15 years of age) were asked to collaboratively create digital audiovisual narratives. In the first project, adolescents seemed to consider their audiovisual materials as transparent and with self-evident meanings. In the second project, adolescents problematized meaning and reflexively examined the design of audiovisual media. We explore two distinct but complementary factors that might help interpret the differences: (a) rapid historical changes in the digital narratives adolescents are exposed to and engage with and (b) methodological differences in the way adolescents were supported and guided during the creation of their audiovisual narratives. Through this analysis, we draw on an ethnographically grounded notion of ‘mediatization’ that helps unpack both rapid transformations in adolescent’s digital mediascape and how digital practices are socially co-constructed in collaborative projects with youth
