What is the best approach to benign paroxysmal positional vertigo in the elderly?

A canalith repositioning maneuver(CRM), such as the Epley or Semont maneuver, should be the first-line treatment for benign paroxysmal positional vertigo (BPPV) in the elderly (strength of recommendation [SOR]: A, several good-quality randomized controlled trials [RCTs])

Motional effects of single trapped atomic/ionic qubit

We investigate theoretical decoherence effects of the motional degrees of freedom of a single trapped atomic/ionic electronically coded qubit. For single bit rotations from a resonant running wave laser field excitation, we found the achievable fidelity to be determined by a single parameter characterized by the motional states. Our quantitative results provide a useful realistic view for current experimental efforts in quantum information and computing.Comment: 3 fig

Self and body part localization in virtual reality: comparing a headset and a large-screen immersive display

It is currently not fully understood where people precisely locate themselves in their bodies, particularly in virtual reality. To investigate this, we asked participants to point directly at themselves and to several of their body parts with a virtual pointer, in two virtual reality (VR) setups, a VR headset and a large-screen immersive display (LSID). There was a difference in distance error in pointing to body parts depending on VR setup. Participants pointed relatively accurately to many of their body parts (i.e. eyes, nose, chin, shoulders and waist). However, in both VR setups when pointing to the feet and the knees they pointed too low, and for the top of the head too high (to larger extents in the VR headset). Taking these distortions into account, the locations found for pointing to self were considered in terms of perceived bodies, based on where the participants had pointed to their body parts in the two VR setups. Pointing to self in terms of the perceived body was mostly to the face, the upper followed by the lower, as well as some to the torso regions. There was no significant overall effect of VR condition for pointing to self in terms of the perceived body (but there was a significant effect of VR if only the physical body (as measured) was considered). In a paper-and-pencil task outside of VR, performed by pointing on a picture of a simple body outline (body template task), participants pointed most to the upper torso. Possible explanations for the differences between pointing to self in the VR setups and the body template task are discussed. The main finding of this study is that the VR setup influences where people point to their body parts, but not to themselves, when perceived and not physical body parts are considered

Around the Fireplace, Westbrook Seminary and Junior College, 1928

Nine Westbrook Seminary and Junior College girls group around the stone fireplace, used for out-of-doors lunches and campfires, in this fall 1928 black & white photo by Kahill-Spratt, Middle Street, Portland, Maine.The girls are roasting hotdogs on sticks and holding white ironstone mugs. They wear skirts and sweaters and jackets. Two wear tams on their heads. The girls smile and laugh.https://dune.une.edu/wchc_photos_students1920s/1013/thumbnail.jp

Intervention for Burnout: A Review of Empirical Evidence

The literature in the field of professional burnout has grown enormously over the past decade. Burnout interventions have been discussed frequently, but with very little empirical justification. Even in the scholarly press, however, most publications have been non-empirical in nature. The current paper examines the existing empirical evidence on interventions for burnout in the helping professions, published from the introduction of the concept in 1974 to mid-1986.Au cours de la dernière décennie, nous pouvons noter un intérêt croissant dans la littérature concernant l'épuisement professionnel. Toutefois, la littérature touchant les interventions auprès des "burnout" est rarement supportée par des recherches empiriques. Il en va de même des publications, sur le sujet, dans les journaux professionnels. L'article qui suit couvre les recherches empiriques sur les interventions auprès des "burnout" travaillant dans une profession reliée à la relation d'aide, depuis l'introduction du concept en 1974 jusqu'en 1986

Students at the Alumni Hall Entrance, ca.1936

Twenty-one young Westbrook Junior College women stand informally in the doorway and on the steps at the Alumni Hall entrance in this ca.1936 sepia toned photograph by Kahill Photo Studios, Portland, Maine. Most cradle books and notebooks in their arms and wear nylons and low heel shoes. Many sport bobbed hair cuts. The young women wear open jackets and coats over their skirts & sweaters and jumpers. Four wear leather jackets and two have on dark peacoats. All are smiling and chatting with each other.https://dune.une.edu/wchc_photos_students1930s/1109/thumbnail.jp

Westbrook Seminary and Junior College girls picnic around the stone fireplace and a makeshift picnic table at the back of the campus in this fall 1928 sepia toned photograph by Kahill-Spratt, Middle Street, Portland, Maine. The girls are standing and wear skirts, sweaters, long stockings and jackets; several wear tams or knit caps on their heads. Many backs are to the camera as they enjoy their food and drink. In the background can be seen the wooden picket fence which separates the Campus from Evergreen cemetery.https://dune.une.edu/wchc_photos_students1920s/1015/thumbnail.jp
