An Ethnographic Inquiry: Contemporary Language Ideologies of American Sign Language
Historically, American Sign Language (an aspect of Deaf culture) has been rendered invisible in mainstream hearing society. Today, ASL’s popularity is evidenced in an ethnolinguistic renaissance; more second language learners pursue an interest in ASL than ever before. Nonetheless, Deaf and hearing people alike express concern about ASL’s place in hearing culture. This qualitative study engages ethnographic methods of participant observation and semi-structured interviewing as well as popular media analysis to understand language ideologies (ideas and objectives concerning roles of language in society) hearing and Deaf Signers hold about motivations and practices of other hearing Signers. Although most hearing ASLers identify as apolitical students genuinely seeking to build bridges between disparate communities, I argue that ASLers are most concerned with hearing Signers’ colonization of the language through commoditization and cultural appropriation
Patient Perspectives of an Intensive Comprehensive Aphasia Program for Stroke Survivors
Introduction: Persons with aphasia (PWA) who participate in intensive comprehensive poststroke language rehabilitation programs make a variety of significant investments. While intensive aphasia programs and intensive comprehensive aphasia programs (ICAPs) are becoming increasingly prevalent across health care settings, patient perspectives of ICAPs have not been explored. The purpose of this qualitative study was to examine patient perspectives about the experience of participating in an ICAP at the University of Montana. The primary research question of this study was: “what is it like to be a PWA in an ICAP?” Methods: Researchers used an interpretive phenomenological approach to conduct nine structured interviews from PWAs who described their lived experiences in the ICAP. All interviews were audiovisually recorded and transcribed from the video recordings. Analysis involved an iterative and collaborative coding process. Transcripts were coded and themes were developed from the PWAs’ shared perspectives. Results: Three primary themes emerged from patient perspectives including: (1) experience with each of the ICAP components is generally positive, (2) we notice the impact of the ICAP on our communication, and (3) relationships with people in the ICAP are important. Discussion: Results support emerging evidence that ICAPs can be a positive experience for PWA due to the perceptible impact on communication improvement and frequent and varied opportunities to interact with others. ICAPs may be a worthwhile investment for PWA, thereby contributing to the cost-benefit utility and implementation feasibility of the service delivery model
Search for C-parity violation in and
Using events recorded in
collisions at 3.686 GeV with the BESIII at the BEPCII collider, we
present searches for C-parity violation in and decays via . No significant
signals are observed in either channel. Upper limits on the branching fractions
are set to be and
at the 90\%
confidence level. The former is one order of magnitude more stringent than the
previous upper limit, and the latter represents the first limit on this decay
channel.Comment: 7 pages, 2 figure
Observation of a charged charmoniumlike structure in at GeV
We study the process at a
center-of-mass energy of 4.26GeV using a 827pb data sample obtained with

partial reconstruction technique, the Born cross section is measured to be
pb. We observe a structure near the
threshold in the recoil mass spectrum, which we denote as the

Observation of and a neutral charmoniumlike structure
Using data collected with the BESIII detector operating at the Beijing
Electron Positron Collider at center-of-mass energies of , 4.26,
and 4.36~GeV, we observe \EE\to \pphc for the first time. The Born cross
sections are measured and found to be about half of those of \EE\to
\pi^+\pi^-h_c within less than 2. In the mass spectrum, a
structure at 4.02~GeV/ is found. It is most likely to be the neutral
isospin partner of the \zcp^{\pm} observed in the process of \EE\to
\pi^+\pi^-h_c is found. A fit to the invariant mass spectrum, with
the width of the \zcpn fixed to that of its charged isospin partner and
possible interferences with non-\zcpn amplitudes neglected, gives a mass of
()~MeV/ for the \zcpn, where the first error is
statistical and the second systematic.Comment: 7 pages, 2 figure
