A complete coverage of the course content does not lead the student to explorative curiosity and to a scientific attitude to knowledge and learning. Interactive hypermedia use will lead to an epistemological quality raising since in that way students’ independence in planning, knowledge acquisition and problem solving might be facilitated and since at the same time tutorial supervision and guidance can be included. Hypermedia have possibilities to provide students with large quantities of information. With network interfacing learning can take place independent of time and place and individualized education will be possible. Combined with CMC (computer mediated communication) and educational software the student has a tool for life-long education within the classroom. At the Växjö University text, images and simulations have been integrated within a hypertext system: Hyperbook (for Macintosh). At the Royal Institute of Technology we develop this concept to use it with computer-based self-study material in mechanics, a project which started in autumn 1990 using HyperCard. At the University of Lund a development of hypertext material in the form of computer illustrated text for a thermodynamics textbook has just started. An example of limits of models will be demonstrated by a computer simulation of a linearized and a non-linearized pendulum.  相似文献

Objective

This study described the epidemiology of child abuse homicides in the state of Kansas from 1994 to 2007. It focused on obtaining significant details on all recorded child abuse homicides in Kansas during this time frame to provide critical information that can be used for future preventive measures.

Methods

A retrospective case review was conducted on data gathered by the Kansas State Child Death Review Board for all cases of “child abuse homicides” that occurred from 1994 to 2007.

Results

A total of 170 child abuse homicide cases in Kansas between 1994 and 2007 were identified. The majority of these cases (63.5%) were considered fatal child physical abuse. There was a predominance of female victims (55.9%). The vast majority of victims were White (78.8%), followed by Black (17.1%). One to 2-year-olds accounted for the largest age group of children who were victimized (33.5%). For cases with known prenatal care status, 74% of mothers received adequate prenatal care. The largest percentage of victims was children of single mothers (40.6%), with no prior history of child abuse (60%). The majority of deaths occurred in the victim's residence (81.8%). The greatest number of deaths occurred secondary to abusive head trauma (42.9%), followed by asphyxia (21.8%). When a trigger was known, 44.2% involved inconsolable crying. The most common perpetrator was the victim's biological father (26.6%), followed by the victim's biological mother (24.9%), then the victim's mother's male paramour (19.8%).

Conclusions

Familiarity with characteristics involved in child abuse homicide allows for opportunities to enlist important preventive measures. Most child abuse homicides occurred at the hands of the victim's biological parents and in the victim's own residence. Prevention should be focused on parent education and coping mechanisms for the frustrating features of crying in normal infants that lead to shaking or abuse.  相似文献
