Work in perceptual dialectology has argued that listeners’ successful identification of accent areas is facilitated by their geographical proximity to a particular region. Montgomery ( 2007 , 2012 ) argues that this proximity effect is mediated by a ‘cultural prominence’ effect, where localities of high cultural salience seem less distant. We explore these claims using an online survey in which listeners were asked to identify the regional origin of speakers of five accents from England's ‘linguistic north’ (Liverpool, Manchester, Crewe, Stoke‐on‐Trent and Macclesfield) from audio clips of four different sentences. We show that the proximity and cultural prominence effects are partially supported, and that the proximity effect is driven by listeners’ likely contact with/experience of the dialect in question. We also show that listeners react differently to different sentences in the same accent. While some sentences are identified correctly very often, others, even for culturally prominent locations with distinctive accents (i.e. Liverpool), are hardly ever correctly identified. We connect this to the geographical distribution of the linguistic features in the clips, and we argue that the presence, absence and range of individual linguistic features should be systematically considered in all perceptual dialectology work which uses audio stimuli.  相似文献

Labor market changes complicate the analysis of black women's status relative to white women because education, occupational attainment, and race–gender are now less predictive of earnings. Low‐wage black women's relative status has improved somewhat from 1970 to 2000, contrary to the well‐documented decrease in relative status reported for all black women wage earners since 1980, but their dramatic occupational upgrading was not responsible for the trend. White‐collar occupational positions formerly responsible for white women's relative earnings advantage no longer deliver that reward, as restructuring has produced a proliferation of bad jobs across occupational groups. This study argues that increasing exposure to precarious work is crucial to understanding changes in low‐wage black women's relative economic status since 1970.  相似文献

Background

Falls are common in older adults and can result in serious injuries. Due to demographic changes, falls and related healthcare costs are likely to increase over the next years. Participation and motivation of older adults in fall prevention measures remain a challenge. The iStoppFalls project developed an information and communication technology (ICT)-based system for older adults to use at home in order to reduce common fall risk factors such as impaired balance and muscle weakness. The system aims at increasing older adults’ motivation to participate in ICT-based fall prevention measures. This article reports on usability, user-experience and user-acceptance aspects affecting the use of the iStoppFalls system by older adults.

Methods

In the course of a 16-week international multicenter study, 153 community-dwelling older adults aged 65+ participated in the iStoppFalls randomized controlled trial, of which half used the system in their home to exercise and assess their risk of falling. During the study, 60 participants completed questionnaires regarding the usability, user experience and user acceptance of the iStoppFalls system. Usability was measured with the System Usability Scale (SUS). For user experience the Physical Activity Enjoyment Scale (PACES) was applied. User acceptance was assessed with the Dynamic Acceptance Model for the Re-evaluation of Technologies (DART). To collect more detailed data on usability, user experience and user acceptance, additional qualitative interviews and observations were conducted with participants.

Results

Participants evaluated the usability of the system with an overall score of 62 (Standard Deviation, SD 15.58) out of 100, which suggests good usability. Most users enjoyed the iStoppFalls games and assessments, as shown by the overall PACES score of 31 (SD 8.03). With a score of 0.87 (SD 0.26), user acceptance results showed that participants accepted the iStoppFalls system for use in their own home. Interview data suggested that certain factors such as motivation, complexity or graphical design were different for gender and age.

Conclusions

The results suggest that the iStoppFalls system has good usability, user experience and user acceptance. It will be important to take these along with factors such as motivation, gender and age into consideration when designing and further developing ICT-based fall prevention systems.

This critical review of the literature on female entrepreneurship problematizes the metanarrative of economic growth and the mechanisms through which it both operates and is maintained. Central to this is the axiomatic ‘underperformance hypothesis’, which states that ‘all else being equal, female entrepreneurs tend to be less successful than their male counterparts in terms of conventional economic performance measures’ (Du Rietz and Henrekson (2000, p. 1). As an axiom, the truth of the ‘underperformance hypothesis’ is taken for granted, and thus it invisibly serves as a starting point, delimiter and interpretive lens for analysis in this field. While it remains invisible, the hypothesis will continue to reproduce the differences between male and female entrepreneurs, and thus the subordination of women to men in the realm of entrepreneurship. The review illustrates how, by associating females with underperformance, the persistent influence of the metanarrative of economic growth has been masked and the image of the female entrepreneur as problematic and inferior to her male counterpart has been reinforced. The authors argue that a postmodern feminist epistemology will destabilize both the metanarrative of economic growth, and the axiomatic ‘underperformance hypothesis’ it supports, thus opening up space for a heterogeneous understanding of (female) entrepreneurship. By questioning accepted knowledge about female entrepreneurs, the review sets the platform for the exploration of new research questions and a broad agenda for future research. Such an agenda is crucial in order to move future research beyond the pervasive influence of the metanarrative of economic growth and its attendant underperformance hypothesis.  相似文献

In this paper we examine schooling inequalities through drawing from the contributions of racialized organizations. We apply the components of this racial theory to offer a new framework for examining racial inequalities in US K-12 schools. We analyze case studies to demonstrate how the four tenants of racialized organizations operate in three schools. In particular, we highlight how these tenants surface through schools' policies (school rules around discipline, language, and tracking) and practices (interactions between students, teachers and staff). We offer a framework for understanding how schools are shaped by the racial hierarchy at the organizational level. We close by considering implications and suggestions for future research.  相似文献
