Language is vital for social interaction, leading some to suggest early linguistic ability paves the way for good adolescent mental health. The relation between age-5 vocabulary and adolescent internalizing symptoms was examined in two U.K. birth cohorts that are nationally representative in terms of sex, ethnicity, and socioeconomic status: the 1970 British Cohort Study (BCS; N = 11,640) and the Millennium Cohort Study (MCS born ~2001; N = 14,754). In the BCS, no relation between receptive vocabulary and age-16 self-reported symptoms was observed (β = 0.00 [−0.03; 0.03]). In the MCS, better expressive vocabulary was associated with more age-14 self-reported symptoms (β = 0.05 [0.02; 0.07]). The direction of this effect was reversed for parent-reported symptoms. All effect sizes were small. The relation between childhood vocabulary and internalizing symptoms varies by generation and reporter.  相似文献

Direct and Indirect Effects of Parenting on the Academic Functioning of Young Homeless Children     

Janette E. Herbers  J. J. Cutuli  Theresa L. Lafavor  Danielle Vrieze  Cari Leibel  Jelena Obradović 《Early education and development》2013,24(1):77-104

Research Findings: Effects of parenting quality on the academic functioning of young homeless children were examined using data from 58 children ages 4 to 7 and their parents during their stay at an emergency homeless shelter. Parenting quality, child executive function, child intellectual functioning, and risk status were assessed in the shelter, and teacher reports of academic functioning were obtained when the children began kindergarten or 1st grade. As hypothesized, parenting quality was associated with children's academic success, and this effect was mediated by executive function skills in the child. Parenting quality also had a moderating effect on risk, consistent with a protective role of high-quality parenting among children with higher risk levels. Concomitantly, children with higher risk and lower parenting quality appeared to be more vulnerable to academic problems. Practice or Policy: In homeless families, parenting may play an especially important role in academic success through multiple pathways, including the development of executive function skills in their children. Policies and practices to support parents and foster the executive function skills of young children in homeless families may be important strategies to promote child academic success. Implications for intervention efforts with homeless parents and children are discussed.  相似文献   

Managing academic personnel flow at universities∗∗     

Danielle Gilliot  Bert Overlaet  Paul Verdin 《Tertiary Education and Management》2013,19(4):277-295

Abstract

Universities experience increasing difficulty in staffing their academic positions. Attracting and retaining highly qualified employees is a general problem that has received much attention in recent HRM literature. But several authors have claimed that the academic career has lost much of its attractiveness. This paper presents seven levers that universities may use to enhance their recruitment and retention power on a difficult job market. Suggestions are made based on experience from innovative organisations, both universities and business organisations. Special attention is given to the creation of multiple and flexible career paths within academia. We contend that a successful application of these suggestions will require major cultural and institutional change at universities.  相似文献   

The contribution of domain-specific knowledge in predicting students' proportional word problem-solving performance     

Asha K. Jitendra  Amy E. Lein  Jon R. Star  Danielle N. Dupuis 《Educational Research and Evaluation》2013,19(8):700-716

This study explored the extent to which domain-specific knowledge predicted proportional word problem-solving performance. We tested 411 seventh-grade students on conceptual and procedural fraction knowledge, conceptual and procedural proportion knowledge, and proportional word problem solving. Multiple regression analyses indicated that all four domain-specific knowledge variables (i.e., conceptual and procedural fraction knowledge, conceptual and procedural proportion knowledge) significantly predicted proportional word problem-solving performance. Conceptual fraction and procedural proportion knowledge contributed the most unique variance (10.0 and 6.7%, respectively, of the total variance) to proportional word problem solving. Procedural fraction and conceptual proportion knowledge each also contributed significant unique variance to proportional word problem solving explaining 5.6 and 2.8%, respectively. The results support the notion that both conceptual fraction and proportion knowledge and procedural fraction and proportion knowledge play a major role in understanding individual differences in proportional word problem-solving performance to inform interventions.  相似文献   

Examining technology integration in middle school STEAM units     

Danielle Herro  Cassie Quigley  Lorraine A. Jacques 《Technology, Pedagogy and Education》2013,22(4):485-498

ABSTRACT

This research draws on a longitudinal study in which middle school math and science teachers enacted STEAM (science, technology, engineering, art and mathematics) teaching in their classroom after participating in intensive STEAM professional development aimed at increasing effective STEAM teaching. The authors address one important aspect in STEAM teaching, technology integration practices of teachers during instruction, and theorise their work using connected learning theory. Qualitative case study is used to identify and describe technology integration themes which emerged during STEAM instruction. Results suggest 17 of the 21 teachers participating in the study demonstrated technology integration involving one or more areas of instructional approaches, assessment and student use. The research expands what we know about how technology can be integrated in STEAM instruction and suggests ways to capitalise on technology to broaden access and appeal to all students during STEAM instruction.  相似文献   

Developing health information literacy: a needs analysis from the perspective of preprofessional health students     

Lana V. Ivanitskaya  Kaitlyn A. Hanisko  Julie A. Garrison  Samantha J. Janson  Danielle Vibbert 《Journal of the Medical Library Association》2012,100(4):277-283

Objective:

The research identified the skills, if any, that health preprofessional students wished to develop after receiving feedback on skill gaps as well as any strategies they intended to use to address these gaps.

Methods:

A qualitative approach was used to elicit students'' reflections on building health information literacy skills. First, the students took the Research Readiness Self-Assessment instrument, which measured their health information literacy, and then they received individually tailored feedback about their scores and skill gaps. Second, students completed a post-assessment survey asking how they intended to close identified gaps in their skills on these. Three trained coders analyzed qualitative comments by 181 students and grouped them into themes relating to “what skills to improve” and “how to improve them.”

Results:

Students intended to develop library skills (64% of respondents), Internet skills (63%), and information evaluation skills (63%). Most students reported that they would use library staff members'' assistance (55%), but even more respondents (82%) planned to learn the skills by practicing on their own. Getting help from librarians was a much more popular learning strategy than getting assistance from peers (20%) or professors (17%).

Conclusions:

The study highlighted the importance of providing health preprofessional students with resources to improve skills on their own, remote access to library staff members, and instruction on the complexity of building health literacy skills, while also building relationships among students, librarians, and faculty.

Highlights

• After receiving feedback on skill gaps, most preprofessional health students intend to develop their information literacy skills.
• Some students report that a trip to the library is a barrier to using library resources.
• Students see the need to build their information evaluation skills, knowledge of citations and plagiarism, and library skills, which they differentiate from Internet skills.
• Students are more likely to identify librarians as sources for assistance in finding information than faculty or peers after receiving individual feedback explaining the role of libraries and library staff members.

Implications

• Students'' health information competencies can be built through assessment and feedback that reveals skill gaps, highlights misconceptions, and offers ideas on how to improve.
• Access to professionally designed self-study resources is needed for students who intend to develop health information competencies on their own.

Face it: The Impact of Gender on Social Media Images     

Jessica Rose  Len Shyles  Kelly Barry  Danielle Biagini  Colleen Hart 《Communication quarterly》2013,61(5):588-607

Social websites like Facebook enable users to upload self-created digital images; it is therefore of interest to see how gender is performed in this domain. A panel used a literature review of pictorial features associated with gender traits, and a sample of Facebook pictures to assess gender stereotypes present in Facebook images. Traits emerging in greater prominence in pictures of males included active, dominant, and independent. Those prominent with female users included attractive and dependent. These findings generally conform to gender stereotypes found in prior research and extend the research regarding stereotypical gender traits displayed in professional media depictions to self-selected social media displays. They also extend the research on gender differences in impression management generally, in both interpersonal communication and social media, to include gender-specific traits that are part of young mens and women's impression management.  相似文献   

Changes in the relationship between joint angle and torque production associated with the repeated bout effect     

Malachy P McHugh  Danielle T Tetro 《Journal of sports sciences》2013,31(11):927-932

A single bout of eccentric exercise induces a protective adaptation against damage from a repeated bout. The aim of this study was to determine whether this repeated bout effect is due to a change in the length–tension relationship. Twelve individuals performed an initial bout of six sets of 10 eccentric quadriceps contractions and then performed a repeated bout 2 weeks later. Eccentric contractions were performed on an isokinetic dynamometer at 1.04 rad?·?s^?1 with a target intensity of 90% of isometric strength at 70° of knee flexion. Isometric strength and pain were recorded before and after both eccentric bouts and on each of the next 3 days. Isometric strength was tested at 30°, 50°, 70°, 90° and 110° of knee flexion. On the days following the initial bout, there was a significant loss of isometric strength at all knee flexion angles except 110° (bout×angle: P?<0.01). On day 2, strength averaged 86% of baseline for 30–90° and 102% of baseline for 110°. Strength loss and pain after the initial bout was contrasted by minimal changes after the repeated bout (pain: P?<0.001; strength: P?<0.01). The repeated bout effect was associated with a rightward shift in the length–tension curve; before the repeated bout, isometric strength was 6.8% lower at 30° and 13.6% higher at 110° compared with values before the initial bout (bout×angle: P?<0.05). Assuming that torque production at 110° occurs on the descending limb of the length–tension curve, the increase in torque at 110° may be explained by a longitudinal addition of sarcomeres. The addition of sarcomeres would limit sarcomere strain for subsequent eccentric contractions and may explain the repeated bout effect observed here.  相似文献
