Students have been slow to adopt e‐textbooks even though they are often less expensive than traditional textbooks. Prior e‐textbook research has focused on adoption behavior, with little research to date on how students perceive e‐textbooks fitting their needs. This work builds upon Task‐Technology Fit (TTF) and Consumer Acceptance and Use of Technology (UTAUT2) theory to present a student‐perspective model of e‐textbook usage. By contextualizing TTF and UTAUT2 to e‐textbooks, the research fills a gap in the literature and provides guidance to researchers and practitioners. The goal of the research is to understand how students perceive their task of learning to fit with e‐textbook technology, and how that fit influences e‐textbook usage and expected performance in their classes. To achieve this goal, the research develops a model to test the relationship between perceived TTF of e‐textbooks and UTAUT2‐defined user characteristics that encourage adoption behaviors, thus facilitating student learning. The findings show that four factors impact a student's perceived TTF: substitution, habit, hedonic motivation, and facilitating conditions. Furthermore, perceived TTF positively correlates with students’ e‐textbook usage and expected performance in classes when using e‐textbooks. While price value exhibits a measurable effect on e‐textbook utilization, it is a minor factor. 相似文献

By providing historical context for the recurring regulatory retreat in the face of structural problems in the news media, this study examines the policy discourse that continues to define the US journalism crisis and government’s inability to confront it. To contextualize this pattern, I compare two historical junctures, the first occurring in the 1940s, exemplified by the Hutchins Commission, and the second occurring in the more recent policy debates during the years 2009–2011, exemplified by the Waldman Report. Both of these historical moments represented a societal response to a journalism crisis, and both entailed deeply normative discussions about the role of media in a democratic society and government’s role in managing that relationship. A comparison of these historical case studies brings into focus recurring weaknesses in liberal reform efforts. Specifically, it highlights what I refer to as the “discursive capture” reflected in common assumptions about the proper relationship between media and government, and how this American paradigm is constrained by an implicit market fundamentalism. 相似文献

The aims of this study were (1) to compare water polo game-related statistics by context (winning and losing teams) and sex (men and women), and (2) to identify characteristics discriminating the performances for each sex. The game-related statistics of the 64 matches (44 men's and 20 women's) played in the final phase of the Olympic Games held in Beijing in 2008 were analysed. Unpaired t-tests compared winners and losers and men and women, and confidence intervals and effect sizes of the differences were calculated. The results were subjected to a discriminant analysis to identify the differentiating game-related statistics of the winning and losing teams. The results showed the differences between winning and losing men's teams to be in both defence and offence, whereas in women's teams they were only in offence. In men's games, passing (assists), aggressive play (exclusions), centre position effectiveness (centre shots), and goalkeeper defence (goalkeeper-blocked 5-m shots) predominated, whereas in women's games the play was more dynamic (possessions). The variable that most discriminated performance in men was goalkeeper-blocked shots, and in women shooting effectiveness (shots). These results should help coaches when planning training and competition. 相似文献

Two algorithms are provided which define two new ways of averaging waveforms. The representative average maintains shape, has average d.c. offset, average amplitude and average position of noise-free input signals whose onset varies in time after a trigger pulse. The synchronous average removes random bipolar noise, the amplitude of which is below a critical threshhold, from a randomly occuring waveform. The latter does not require a trigger pulse, maintains its shape, has an average d.c. offset and average amplitude. Its position in the output field is such that the centroid of the waveform is placed in the center of the field. Both methods involve the definition of average phase angle and a quantity called the angular standard deviation. 相似文献

This study provides evidence regarding the controversy about the relationship of socioeconomic status (SES) and ethnicity to self-concept. Subjects were 345 first-, second-, and third-grade children of low SES (180 were black) attending inner city schools in a large metropolitan area. The Purdue Self Concept Scale was the measure of self-concept. There was a decline in self-concept with grade level (p < .01), and blacks scored higher than whites (p < .01). An analysis of black second-grade children's scores indicated that the race difference was due to the high scores of those with welfare status. Low expectations resulting from SES and ethnic segregation, effects of the black pride movement, and defensiveness are considered as possible explantions. 相似文献

Studies in Israel relating to attitudes of various ethnic, cultural and religious groups towards the disabled were reviewed. The results indicate that although there were differences in attitudes towards the disabled, these differences appear to be a function of interaction effects between many other variables and not necessarily only related to ethnic, cultural, and religious affiliation. 相似文献

Age curves, which relate age to creativity or exceptional achievements, seem to take two forms: some artists bloom early (Picasso), others later in life (Cézanne). We argue that this objective fact is not related to their mode of creation according to which some artists proceed by drawings made prior to the painting's execution, while others are more likely to imitate and achieve this through color and the process of painting itself.
