The Rise in Single-Mother Families and Children’s Cognitive Development: Evidence From Three British Birth Cohorts     

Susan Harkness  Paul Gregg  Mariña Fernández-Salgado 《Child development》2020,91(5):1762-1785

This article assessed changes in the association between single motherhood and children’s verbal cognitive ability at age-11 using data from three cohorts of British children, born in 1958 (n = 10,675), 1970 (n = 8,933) and 2000 (n = 9,989), and mediation analysis. Consistent with previous studies, direct effects were small and insignificant. For those born in 1958 and 1970 indirect effects, operating through reduced economic and parental resources, were associated with −.107-SD to −.156-SD lower attainment. Differences between the two cohorts, and by children’s age when parents separated, were insignificant. For the 2000 cohort, effect sizes for children born to single mothers did not change significantly (−.112-SD) but attenuated for children whose parents separated in early childhood (−.076-SD) or while of school age (−.054-SD).  相似文献

Signaling functions of the second-order CS: Partial reinforcement during second-order conditioning of the pigeon’s keypeck     

Michael E. Rashotte  Beverly S. Marshall  Jeffrey M. O’Connell 《Learning & behavior》1981,9(2):253-260

The signaling function of the second-order CS (S2) was manipulated in second-order autoshaping by arranging a partial reinforcement schedule. S2 was paired with a well-conditioned first-order CS (SI) on a continuous reinforcement or a 25% reinforcement schedule in different groups. Schedule of reinforcement did not influence the number of S2-S1 pairings required to establish keypecking to S2. However, in the postacquisition sessions, responding to S2 was initially weaker but persisted for many more sessions on the 25% schedule than on the 100% schedule. The data indicate that S2-S1 pairings are responsible both for the acquisition of second-order keypecking to S2 and for the subsequent conversion of S2 into an inhibitory stimulus.  相似文献   

Beatrix Potter: A Hundred Years in Translation     

Dana?CocargeanuEmail author  Eithne?O’Connell  áine?McGillicuddy 《Children‘s Literature in Education》2016,47(4):374-391

This year, 2016, marks the 150th anniversary of the birth of Beatrix Potter (1866–1943), the much-loved author and illustrator of children’s books. Although translation has made a vital contribution to her international success, Potter’s work remains relatively under-researched from a translation studies perspective. This article aims to provide a clearer picture of Potter’s work in translation over the last hundred years. It identifies early translated editions and discusses Potter’s involvement in their preparation, before examining the appearance of her stories in translation around the world and outlining particular trends in Potter translation. This study is based on extensive research using numerous databases, Potter’s published biographies and correspondence, and on an analysis of the first French editions of her tales. The study reveals that the first published translations of Potter’s works are both of an earlier date and more numerous than is recognised in existing scholarship. It also shows that Potter’s preferred approach in the translation of her stories into French was to adapt the tales to their new French readership, rather than staying close to the originals. Her works are found to have been extensively translated during the last century, especially into European languages, as well as into a significant number of Asian languages. Other matters discussed include the involvement of Potter’s official publisher, Warne, in the publication of international editions; the existence of translations based on American editions with new illustrations; and the posting of online translations by Potter enthusiasts.  相似文献   

‘I’m just not that comfortable with technology’: student perceptions of and preferences for Web 2.0 technologies in reflective journals     

Timothy S. O’Connell  Janet E. Dyment 《Journal of Further & Higher Education》2016,40(3):392-411

Encouraging reflective practice and developing reflective practitioners is a goal of many disciplines in higher education. A variety of pedagogical techniques have been used to promote critical reflection including portfolios, narratives and reflective journals. Over the past decade, the use of Web 2.0 technologies with students has been increasingly adopted in higher education settings and many educators have integrated these technologies into reflective assignments. These educators assume that students, who are members of the Net Generation, are technologically savvy and have the ability to integrate the use of Web 2.0 technologies into learning. However, while there have been studies examining the outputs of reflective assignments using Web 2.0 technologies such as blogs, e-portfolios and wikis, there has been little research examining whether or not students actually use technology for these types of assignment if given the choice. Therefore, the purpose of this study was to explore if technology was appropriated or rejected by students for a reflective journaling assignment. Results are based on a content analysis of 42 student journaling assignments and interviews with eight students. Findings suggest that (1) students are not as technologically competent as assumed; (2) students chose to use basic/fundamental technologies (e.g. word processing) because they viewed it as the easiest way to complete the reflective journaling assignment; (3) student perceptions of what makes an assignment ‘good’ influenced their choice to use Web 2.0 technologies; and (4) overarching student perceptions of higher education and learning impacted their appropriation of technology. Implications are discussed and recommendations for both research and practice are made.  相似文献   

Assessing and Predicting Small-Group Literacy Instruction in Early Childhood Classrooms     

Kristin Sue Farley  Shayne Piasta  Mine Dogucu  Ann O’Connell 《Early education and development》2017,28(4):488-505

Research Findings: The present study assessed the extent to which early childhood educators utilized small-group literacy instruction and explored factors potentially associated with the use of this evidence-based practice. The classroom activities of 83 early childhood educators were observed in the fall and spring, and videos were coded to calculate time spent in small-group literacy instruction. Educators completed questionnaires indicating classroom adult:child ratios, literacy beliefs, and feelings of self-efficacy. Classroom Assessment Scoring System scores for classroom organization and instructional support measured the quality of classroom management and instructional interactions, respectively. On average, educators provided 11.4 min (SD = 10.6) of small-group literacy instruction a day. It is notable that many educators provided little or no small-group literacy instruction. Negative binomial regression analyses indicated that educators with better classroom management, higher quality instructional interactions, and lower adult:child ratios were more likely to use small-group literacy instruction. Educators’ beliefs and feelings of self-efficacy were not associated with the use of small-group literacy instruction. Practice or Policy: Educators may be better able to provide small-group literacy instruction in contexts affording low adult:child ratios and high levels of classroom management and instructional support, all of which are malleable factors that can be changed via policy or professional development.  相似文献   

Re-referral to child protective services: the influence of child, family, and case characteristics on risk status   总被引：2，自引：0，他引：2  

Connell CM  Bergeron N  Katz KH  Saunders L  Tebes JK 《Child abuse & neglect》2007,31(5):573-588

INTRODUCTION: This study examines child, family, and case characteristics that impact rates of re-referral to Child Protective Services (CPS) using data on all closed CPS investigations for the state of Rhode Island between 2001 and 2004. METHOD: A longitudinal dataset of all referrals to CPS was created using state submissions to the National Child Abuse and Neglect Data System (NCANDS). After excluding children whose initial CPS investigation resulted in removal from the home, a Cox proportional hazards model was tested to examine factors impacting the likelihood of re-referral. RESULTS: Consistent with other research in this area, the initial 6-month period following case disposition is the period of greatest risk of re-referral. Approximately 13% of cases experienced a recurrent allegation during the first 6-month period; an additional 14% experienced a re-referral over the following 12-month period; 7% during the next 12-month period. Family poverty was the strongest predictor of re-referral, though a number of child and case characteristics were significantly related to recurrence. Cases that were substantiated at index were significantly less likely to result in a new allegation, though substantiated cases of physical abuse or those receiving post-investigation services were at higher risk. CONCLUSIONS: Children from families facing multiple stressors (e.g., low SES, parental substance abuse child disability) are at highest risk of re-referral to CPS and may benefit from the development of preventive services targeted immediately following case closings within CPS.  相似文献   

Patterns of Instructional-design Factors Prompting Reflective Thinking in Middle-school and College Level Problem-based Learning Environments     

Hae-Deok Song  Barbara L. Grabowski  Tiffany A. Koszalka  William L. Harkness 《Instructional Science》2006,34(1):63-87

Reflective-thinking skills are important in problem-based learning environments as they help learners become deeply engaged in learning. The literature suggests several instructional-design factors (e.g., environment, teaching methods, scaffolding tools) that may prompt reflection in learners. However, it is unclear whether these factors differ based on age or developmental stage. The results of this study indicate that middle-school students perceive the learning environment factor as more important to prompting their thinking, while college students perceive the scaffolding methods factor as more important. While the elements clustered into two factors, most college students disagreed with their helpfulness in prompting reflective thinking, a finding opposite to that obtained for middle-school students. Different patterns were also found between learners’ perceptions of the most helpful elements within each factor. Based on these results, suggestions are given for designing developmentally and age-appropriate PBL learning environments that support reflective thinking.  相似文献   

Cataglyphis     

R. D. Harkness B.Sc.  M.B.  B.S.  R. Wehner Dr.Phil.Nat. 《Endeavour》1977,1(3-4)

Cataglyphis is an ant of desert regions and has a behavioural pattern comparable with that of the bee, but much easier to study. It has a well-developed system of foraging and navigating and a social organisation well adapted to its environment. This review, by two independent research workers who have devoted much time to field studies, is the first to bring together most of the existing information about these fascinating insects.  相似文献
