Rats confronted with the onset of a light gradient display a transient increase in locomotion called theactivity response (AR) and a dark preference (Godsil & Fanselow, 2004). These experiments demonstrate that the magnitude of the AR can be blunted
with Pavlovian fear-conditioning procedures via associative and nonassociative fear. Although manifested in decreased locomotion,
the blunted AR effect was not due to increased freezing or immobility behaviors. Instead, rats displayed reduced rearing and
an increase in a class of behaviors calledstationary activity. These results suggest that the lighting differential supplied by the cue influences the topography of defensive behavior
and reduces the expression of freezing. This procedure provides a means by which to examine learned and unlearned defensive
responses to the same stimulus. 相似文献

OBJECTIVE: The aim of this study was to examine the trajectory of cases through four systems: child protection, law enforcement, the dependency courts, and the criminal courts. METHOD: This study focused on a county selected from a 41-county telephone survey conducted for the National Incidence Study of Child Abuse and Neglect (NIS-3). For this analysis prospective samples were drawn from law enforcement (n=225) and the county child protection (CPS) agency (n=225) and followed through in-depth case tracking across all agencies and through both the dependency and criminal court systems. RESULTS: The percentage of CPS cases opened in dependency court was similar to prior studies (29%), but the acceptance and prosecution rates were much higher--92% of the cases referred from CPS, including many cases of physical abuse. Compared to referrals from CPS to law enforcement (93%), few cases were referred from law enforcement to CPS (17%). Anecdotally, case referral patterns appeared to be influenced by communication patterns and mutual positive regard, regardless of the collaborative protocols in place. One of the most instructive findings was the degree of difficulty in tracking cases across organizations and the types of obstacles that impeded success. Disorganization was not an issue, rather internal structures set up to facilitate intra-organizational processing were the same structures that actually impeded cross-organizational case finding. CONCLUSIONS: It is not sufficient to rely on the existence of multi-disciplinary teams or Child Advocacy Centers to ensure collaboration. More attention to daily tasks and activities as well as the nature and quality of communication is warranted. On the technical side, use of common case identifiers on cases that are cross-referred is strongly recommended. Future studies should broaden the scope of inquiry to include the consequences of all case trajectories, rather than solely focusing on the justice system. 相似文献

A concise review is presented of the essential elements of the book publishing and bookselling business in a complex and diverse
market. Demographics create the diversity while Arabic is the one language spoken across a multitude of different countries.
Three features are common to all of these countries and they are: the dominance of English as the second language, education
has and will remain to be a priority, and economic pressures cause price sensitivity to be a major challenge especially in
the educational market segments. It is the price sensitivity as a key factor for the lack of respect for intellectual property
and copyright regulations. A review of distribution and retail stores is a very important topic in relation to this complex
collection of countries. The emergence of e-books is discussed especially in the educational, professional and reference market
segments. Finally, there is a review of the Arabic language publishers and local book fairs to bring this article to closure. 相似文献

This paper is about the experience of preparation for incorporation in a sixth form college. The purpose of the paper is to take an analytical and reflective view of recent practice and developments which may have applications for all education managers facing externally imposed change. Its focus is on communication and consultation structures, the changing balance of power as institutions become independent of local authorities, and industrial relations in a new culture. It concludes that, without a full understanding of internal processes and structures and a strategy for strengthening them, colleges will continue to be ill‐equipped for survival as incorporated institutions. 相似文献

The present study aims to explore the use of assessment in mathematics content courses for future elementary school teachers.
Analysis of self assessment data on mathematical understanding and peer assessment data on oral mathematical presentation
showed that pre-service teachers had a balanced understanding of procedural knowledge and problem solving. Conceptual understanding
was not in the structure of pre-service teachers’ mathematical knowledge. Understandings of conceptual knowledge, procedural
knowledge, and problem solving had no meaningful effects on gains in mathematics performance. Aspects of oral mathematical
presentation were associated with improved understanding of procedural knowledge and in particular conceptual knowledge. The
result of the study calls for a conceptual approach to mathematical knowledge and sufficient mathematical problem solving
in college-level mathematics content courses and in particular the infusion of assessment into college-level mathematics education
for pre-service teachers. 相似文献
