Brain injury research in sport employs a variety of physical models equipped with accelerometers. These acceleration signals are commonly processed using filters. The purpose of this research was to determine the effect of applying filters with different cutoff frequencies to the acceleration signals used as input for finite element modeling of the brain. Signals were generated from reconstructions of concussion events from American football and ice hockey in the laboratory using a Hybrid III headform. The resulting acceleration signals were used as input for the University College Dublin Brain Trauma Model after being processed with filters. The results indicated that using a filter with a cutoff of 300 Hz or higher had little effect on the resulting strain measures. In some cases there was some effect of the filters on the peak linear (8–30g) and rotational measures (1000–4000 rad/s2), but little effect on the finite element strain result (approximately 2–6 %). The short duration and high magnitude accelerations, such as the puck impact, were most affected by the cutoff frequency of different filters.  相似文献

ABSTRACT

Increased global communication is adjusting traditional models of cross-cultural communication. Specifically, changes in international communication processes have caused increased scrutiny of cross-culture adaptation theory. This is especially true when focusing on the difference between cultural adaptation and functional fitness. The purpose of this research is to address changes in global communications by testing to see if there is a difference between two important theoretical concepts within cross-cultural adaptation theory – linear and non-linear adaptation. Findings indicate that cultural sojourners do not equate cross-cultural adaptation with linear models of functional fitness. Models that equate the two should be revisited.  相似文献

Myths are ill‐founded beliefs held uncritically by persons or groups about other persons or groups. Such myths hinder the communication process and lead to negative feelings or attitudes toward older persons with hearing loss. Hudson, Dancer, Patterson, Reynolds, and Tillery (1990) highlighted five common myths of hearing loss and aging. This article explores whether older persons themselves accept these and other myths presented by the DanPat, a 30‐item questionnaire with “Agree‐Disagree” statements such as the following: “Hearing Aids are Best Left to younger Persons Who Can Learn to Use Them,” or “Persons with Hearing Loss are Paranoid and Suspicious.”

Twenty older persons attending a Senior Companions and Foster Grandparents Health Fair filled out the DanPat with the following results to the 30 statements: informed about 14 of the statements; misinformed about 2 statements; and didn ‘t know the correct answer to 14 statements. Of the five prevalent myths presented by Hudson et al., this group of older adults still believes only one, that persons with hearing loss are excellent lipreaders. They don't know what to believe about two others, and they have discarded the remaining two. This article highlights the DanPat and provides correct answers to the questionnaire.  相似文献

The Artist Initiative at the San Francisco Museum of Modern Art (SFMOMA) is piloting models for increased collaboration between conservators and curators through joint work with artists. We seek a more integrated, holistic approach to the care and research of our collection. The project, funded by the Andrew W. Mellon Foundation, comprises five robust research engagements that serve the curatorial collecting departments of the museum (Photography, Painting and Sculpture, Media Art, and Architecture and Design). Three of the projects are monographic studies, examining the work of Ellsworth Kelly, Vija Celmins, and Julia Scher in depth, while two more are thematic, exploring modes of displaying digitally-driven design objects, and developing strategies for addressing the problem of color shift common to photographic prints made with experimental materials during the 1970s and 1980s. The Artist Initiative is also charged with developing hybrid working spaces to advance collaborative approaches to collections research at the museum's new downtown campus and at SFMOMA's new Collections Center in South San Francisco. These spaces include the Collections Workroom, a 56?sq?m (600?sq?ft) space that functions as a studio for visiting artists, a conservation laboratory, an interview suite, and a classroom at SFMOMA's downtown campus. At the Collections Center, a 121?sq?m (1300?sq?ft) Mock-Up Gallery has been built as a working model of one of the museum's new galleries. A functional exhibition space, the Mock-Up Gallery is also a venue for interviewing artists, prototyping exhibition formats, and meeting with students, scholars, museum staff, and community members. With the goal of contributing to critical discourses in contemporary art history, art conservation, and public engagement, each of the Artist Initiative projects includes a colloquium that will bring experts from multiple fields together with the featured artists. Thereafter we aim to share our findings widely through public programs and a range of publications, both digitally and in print.  相似文献

In this paper we consider discourses of friendship and belonging mobilised by girls who are not part of the dominant ‘cool’ group in one English primary school. We explore how, by investing in alternative and, at times, resistant, discourses of ‘being nice’ and ‘being normal’ these ‘non-cool’ girls were able to avoid some of the struggles for dominance and related bullying and exclusion found by us and other researchers to be a feature of ‘cool girls’ groupings. We argue that there are multiple dynamics in girls' lives in which being ‘cool’ is only sometimes a dominant concern. There are some children for whom explicitly positioning themselves outside of the ‘cool’ group is both resistant and protective, providing a counter-discourse to the dominance of ‘coolness’. In this paper, which is based on observational and interview data in one school in the south of England, we focus on two main groupings of intermediate and lower status girls, as well as on one ‘wannabe’ ‘cool girl’. While belonging to a lower status group can bring disadvantages for the girls we studied, there were also benefits.  相似文献

This study describes the development of emotional and behavioral regulation in a regional cohort of children born extremely preterm (<28 weeks gestational age, n = 39), very preterm (<34 weeks gestational age, n = 56), and full term (n = 103). At 2 and 4 years, children born at younger gestational ages demonstrated poorer self-regulation across multiple contexts spanning observed interactions, formal cognitive testing, and parental report of child behavior at home. Among children born preterm, the 2 strongest predictors of impairments in self-regulation were the presence of moderate-to-severe cerebral white matter abnormalities on neonatal magnetic resonance and a less sensitive parenting style when children were aged 2 years. Findings support the importance of early neurological development and parenting for developing regulation in children born very preterm.  相似文献
