This article queries whether consonant sonority (sonorant vs. obstruent) and status (coda vs. onset) within intervocalic clusters influence syllable-based segmentation strategies. We used a modified version of the illusory conjunction paradigm to test whether French beginning, intermediate, and advanced readers were sensitive to an optimal “sonorant coda–obstruent onset” sonority profile within the syllable boundaries as a cue for a syllable-based segmentation. Data showed that children used a syllable-based segmentation that improved with reading skills and age. The results are discussed to support that the visual letter detection within pseudowords primarily and early relies on acoustic-phonetic cues within the syllable boundaries, whereas the syllable effect seems to be developmentally constrained by reading skills and age. 相似文献

In this paper, we present a low cost and equipment-free blood filtration device capable of producing plasma from blood samples with mL-scale capacity and demonstrate its clinical application for hepatitis B diagnosis. We report the results of in-field testing of the device with 0.8–1 ml of undiluted, anticoagulated human whole blood samples from patients at the National Hospital for Tropical Diseases in Hanoi, Vietnam. Blood cell counts demonstrate that the device is capable of filtering out 99.9% of red and 96.9% of white blood cells, and the plasma collected from the device contains lower red blood cell counts than plasma obtained from a centrifuge. Biochemistry and immunology testing establish the suitability of the device as a sample preparation unit for testing alanine transaminase (ALT), aspartate transaminase (AST), urea, hepatitis B “e” antigen (HBeAg), hepatitis B “e” antibody (HBe Ab), and hepatitis B surface antibody (HBs Ab). The device provides a simple and practical front-end sample processing method for point-of-care microfluidic diagnostics, enabling sufficient volumes for multiplexed downstream tests. 相似文献

Abstract Previous research on laterality in sport suggests an over-representation of left-handers in interactive sports such as tennis and cricket. These findings potentially reflect left-handers' advantage over their right-handed competitors in those sports. Although considered crucial for successful performance, the tactical component of their superiority has yet to be analysed. Two studies were conducted to test for a side bias in tennis players' tactical preferences. In the first study, 108 right- and left-handed players of varying skill watched rallies on a computer screen and had to indicate where they would place the ball in the opposing half. The results showed the tactical preference of players to place more balls on a left-handed opponent's mostly stronger forehand side compared with when faced with a right-hander. In the second study, 54 professional tennis matches involving right- and left-handers were analysed with respect to ball placement frequencies on the opponent's backhand side. Significantly fewer balls were hit to the backhand side of a left-handed opponent, thus replicating the findings of Study 1 in on-court situations. Both studies indicate players' preference to place shots to their right irrespective of their opponent's handedness. Findings support the assumption that left-handers might enjoy a strategic advantage in tennis. 相似文献

ABSTRACTThe aim of this trial was to compare an eight-week individual movement quality versus traditional resistance training intervention on movement quality and physical performance. Forty-six trained adults were randomised to a movement quality-focused training (MQ) or a traditional resistance training (TRAD) group, and performed two individualised training sessions per week, for 8 weeks. Session-RPE (sRPE) was obtained from each session. Measures of movement quality (MovementSCREEN and Functional Movement Screen (FMS)) and physical performance were performed pre- and post-intervention. All measures improved significantly in both groups (3–14.5%, p = <0.005). The between-group difference in MovementSCREEN composite score was not statistically significant (0.3, 95% CI ?3.4, 4.1, p = 0.852). However, change in FMS composite was significantly greater in MQ (1.3, 95% CI 0.8, 1.8, p < 0.001). There were no significant between-group differences in physical performance (p = 0.060–0.960). The mean sRPE was significantly lower in MQ (5.25, SD 1.2) compared to TRAD (6.6 SD 1.0, p = <0.001). Thus, although movement quality scores were not distinctly greater in the MQ group, a movement quality specific intervention caused comparable improvements in physical performance compared to traditional resistance training but at lower perceived training intensity. 相似文献

In the struggle to remain true to their technical assistance and civic engagement missions in an era of shrinking budgets and increasingly complex accountability claims, land grant universities have developed different engagement strategies to contribute to the development of surrounding communities. Drawing on Flora and Flora’s (in Ann Am Acad Polit Soc Sci, 48, 1993) assertion that a strong and “entrepreneurial” social infrastructure is critical for facilitating lasting change and development in communities (particularly rural communities), this article presents a case study of a land grant university’s engagement with a community landcare group from the perspective of building social capacity in surrounding communities. This case explores Virginia Tech’s involvement in facilitating and supporting Catawba Landcare using three theoretical frames—Ronald Heifetz’s concept of “holding environments” as a safe and facilitated space where social learning can occur; ecological and social entrepreneurship and the roles and functions required to support these forms of entrepreneurship; and the concept of learning action networks in which otherwise disparate partners are linked under common goals and collectively learn how to manage the situation at hand. Using these three theoretical frames, this paper posits landcare as a model of engagement for land grant universities thus contributing to the construction of social infrastructure. 相似文献

In order to better understand the effects of student-life stress on Education and Health Service majors (n?=?195) at a private, religious, Midwestern university in the USA, we assessed student perception of overall stress level and physical stress level using the Student-life Stress Inventory. The targeted sample consisted of students with declared majors that lead to careers involving interaction with vulnerable populations (i.e., children, individuals with disabilities, patients). Women in this study experienced a significantly higher (F?=?7.092 [1195], p?=?.008) overall stress level than their male counterparts. When the physical stress reaction scores were isolated, women still experienced significantly higher stress levels (F?=?7.758 [1195], p?=?.01). Regardless of gender, seniors and graduate students had an overall stress difference that was 11 points below that of freshman students in overall stress scores. There was a significant difference in the overall stress score (F?=?6.484 [2181], p?=?.001) between students who took 18 or more credit hours and those who took less. Students who worked more than four hours per week had a significantly higher overall stress level. Students in the age category 23+ had significantly less physical stress. There was a significant difference between students who prayed at least daily and students who never pray (F?=?1.114 [3188], p?=?.03). This study provides a valuable insight into the characteristics of individuals more likely to have difficulties adjusting to the demands of college life and the inherent stress of a profession in Education or Health Service. 相似文献
