Because the characteristics of children vary greatly from age to age, the knowledge and techniques that their caregivers need to have likewise vary a great deal. Similarly, the pleasures and the stresses of caring for different age groups also vary. Not surprisingly, most caregivers have preferences in terms of the age of children they prefer to work with.Gerri Ginsburg and Marcy Whitebook are Directors of the Child Care Employee Project, a national clearinghouse for information on child care staff working conditions.

Video communication systems for deaf people are limited in terms of quality and performance. Analysis of visual attention mechanisms for sign language may enable optimization of video coding systems for deaf users. Eye-movement tracking experiments were conducted with profoundly deaf volunteers while watching sign language video clips. Deaf people are found to fixate mostly on the facial region of the signer to pick up small detailed movements associated with facial expression and mouth shapes. Lower resolution, peripheral vision is used to process information from larger, rapid movements of the signer in the video clips. A coding scheme that gives priority to the face of the signer may be applied to improve perception of video quality for sign language communication.  相似文献

Children's emotionality--fear, anger, and joy--observed outside of the relationship with the mother (in standard laboratory paradigms), and within that relationship (in mother-child interactions), and mothers' responsiveness, all at 9 and 14 months, were examined as predictors of the reunion behaviors in the Strange Situation at 14 months in 112 children. Many predictors were linked to the reunion behaviors, but most of those relations were at least partially mediated by children's separation distress, which itself strongly predicted the reunion behaviors. Those relations were no longer significant when distress was controlled. Several links, however, remained significant, and they were unmediated by distress: Almost all involved measures assessed within the context of the mother-child relationship. In particular, possible markers of a suboptimal relationship (children's dampened joy and increased anger in interactions with the mother, poor maternal responsiveness) were associated with more avoidance and resistance upon reunion, even after accounting for the strong impact of distress. Studying how factors measured outside of and within early relationships influence the components of the attachment system may foster understanding of child behavior in the Strange Situation.  相似文献

Higher Education Institutions (HEIs) across the world have found themselves faced with new challenges on issues of ethics. Much of this has been centred on issues of assessment: plagiarism, buying essays, sharing/lending of previously passed work and the stealing of marked/returned work of others. Institutions still treat academic misconduct as largely a behavioural difficulty rather than an issue of ethics (or education), suggesting that academia places a far greater emphasis on combating new forms of dishonesty than it does on encouraging ethical habits and a healthy ethical environment. To date, the majority of research in this area has examined these forms of academic misconduct from the point of view of the student and/or the university, with the perspective of academics receiving very limited attention. Our hypothesis is that academics are perhaps best placed to provide the education needed to create and sustain an ethical environment, and we argue that being ‘ethically aware’ is a critical factor in the development of academic competence for all parties. This study adds to existing research in three ways: firstly, by highlighting the importance of an overall framework for an ethical environment within HEIs; secondly, by suggesting an ecological model of key parties (the university, students and academics) with responsibility for this environment in assessment; and thirdly, by including new evidence (generated by a survey of academics) to extend our understanding of their views on these issues.  相似文献

The practice of sexting is becoming increasingly common among college students but has the potential to both initiate productive interactions with others and interfere with relationship development. The purpose of this paper is to report on the findings of a study on sexting among college students and to provide a framework through which practitioners working with this population would be able to effectively intervene. Implications for clinical practice include more specific assessment questions for practitioners, focus on better managing riskier behavior, and guidance toward using technology in relationally responsible and supportive ways.  相似文献

We evaluated whether having a naturally acquired mentor during adolescence was associated with improved adult outcomes among youth with learning disabilities (YLD). Mentored youth were more likely to have graduated from high school, reported a higher level of self‐esteem, and reported a higher overall number of positive outcomes than nonmentored youth. Mentorship by teachers/guidance counselors was associated with larger differences in high school graduation rates and self‐esteem compared to nonmentored youth whereas mentorship by nonteachers was associated with smaller changes in self‐esteem and no differences in high school completion rates. Future research should include more in‐depth, objective assessments of youths’ learning disabilities, consideration of interactions with concurrent risk factors, and efforts to clarify optimal strategies for mentoring support of YLD.  相似文献

The function of accurately monitoring one’s own learning is to support effective control of study that enhances learning. Although this link between monitoring accuracy and learning is intuitively plausible and is assumed by general theories of self-regulated learning, it has not received a great deal of empirical scrutiny and no study to date has examined the link between monitoring accuracy and longer-term retention. Across two studies, college students paced their study of key-term definitions (e.g., “Proactive interference: Information already stored in memory interferes with the learning of new information”). After all definitions were studied, participants completed practice cued recall tests (e.g., “What is proactive interference?”) in which they attempted to type the correct definition for each term. After each test trial, participants judged how much of their response was correct. These study-test-judgment trials continued until a definition was judged as correct three times. A final cued recall test occurred two days later. In Study 1, judgment accuracy was manipulated experimentally, and in Study 2, individual differences in accuracy were examined. In both studies, greater accuracy was associated with higher levels of retention, and this link could not be explained by differential feedback, effort during study, or trials to criterion. Results indicate that many students could benefit from interventions aimed at improving their skill at judging their learning.  相似文献
