Anaphase in budding yeast is triggered by cleavage of the central subunit, Scc1, of the chromosomal cohesin complex by the protease separase. Here we show that separase also cleaves the kinetochore-associated protein Slk19 at anaphase onset. Separase activity is further required for proper localisation of a stable Slk19 cleavage product to the spindle midzone in anaphase. Slk19 cleavage and localisation are necessary to stabilise the anaphase spindle, and we show that a stable spindle is a prerequisite for timely exit from mitosis. This demonstrates separase cleavage of targets other than cohesin in the orchestration of high fidelity anaphase.
Smartphones and tablets incorporate built-in accessibility features, but little is known about their impact within the visually impaired population. This study explored the use of smartphones and tablets, the degree to which they replace traditional visual aids, and factors influencing these decisions. Data were collected through an anonymous online survey targeted toward visually impaired participants above the age of 18, whom had been using a smartphone or tablet for at least three months. Among participants (n = 466), 87.4% felt that mainstream devices are replacing traditional solutions. This is especially true for object identification, navigation, requesting sighted help, listening to audiobooks, reading eBooks and optical character recognition. In these cases, at least two-thirds of respondents indicated that mainstream devices were replacing traditional tools most or all of the time. Users across all ages with higher selfreported proficiency were more likely to select a mainstream device over a traditional solution. Our results suggest that mainstream devices are frequently used amongst visually impaired adults in place of or in combination with traditional assistive aids for specific tasks; however, traditional devices are still preferable for certain tasks, including those requiring extensive typing or editing. This provides important context to designers and rehabilitation personnel in understanding the factors influencing device usage.
Although this review reports an association between sensory loss and couples' relational and psychosocial wellbeing, the results should be viewed with caution given that relatively few studies on couples' experiences of acquired sensory loss exist, and many have methodological limitations.
The findings highlight the need to support the mental health of couples living with sensory loss and indicate the importance of considering the intimate relationship in future studies.
Our search yielded 20 studies. Regarding sample demographic characteristics, most participants were Caucasian and most caregivers were related to the patient by marriage. Regarding design characteristics, 18 studies were quantitative and two were qualitative; five were cross-sectional, ten were longitudinal, one was experimental, and four were interventional. Most outcomes were psychosocial and the interventions were largely psycho-educational in nature. Large variation in quality of the studies emerged (six were rated as low quality, seven as adequate, and seven as high quality). Understudied populations include racial/ethnic minorities and same-sex couples. More work is needed to understand functioning during survivorship and impacts on patient medical outcomes, and to truly leverage the dyad to optimize individual- and relationship-level adjustment.
The results highlight the need to support the well-being of adults with sensory loss and their spouses in rehabilitation, and the importance of both intra- and interpersonal coping in the adjustment process. Implications for rehabilitation Rehabilitation specialists and social workers working with adults with sensory loss should, where possible, incorporate family members into support plans. Rehabilitation specialists and social workers working in sensory rehabilitation should be mindful of how the coping styles of one partner can impact the well-being of their significant other. In addition to promoting positive coping behaviors, such as planning and support seeking, rehabilitation specialists and social workers should also take care to identify and reduce maladaptive coping behaviors such as avoidance and distraction. Online and print information for spouses on how to cope with a partner's sensory loss should be available and accessible for couples attending sensory rehabilitation clinics.
Deaf learners are a highly heterogeneous group who demonstrate varied levels of academic achievement and attainment. Most prior research involving this population has focused on factors facilitating academic success in young deaf children, with less attention paid to older learners. Recent studies, however, have suggested that while factors such as early cochlear implantation and early sign language fluency are positively associated with academic achievement in younger deaf children, they no longer predict achievement once children reach high school age. This study, involving data from 980 college-bound high school students with hearing loss, examined relations between academic achievement, communication variables (audiological, language), and use of assistive technologies (e.g., cochlear implants [CIs], FM systems) and other support services (e.g., interpreting, real-time text) in the classroom. Spoken language skills were positively related to achievement in some domains, while better sign language skills were related to poorer achievement in others. Among these college-bound students, use of CIs and academic support services in high school accounted for little variability in their college entrance examination scores.
The current study's findings provide support for a relationship-focused perspective of spousal psychological adjustment in the context of DSL. Further, couples' sensory loss-related communication is presented as a potential intervention target to enhance spouse perceived support and psychological well-being.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
