The Public Knowledge Project is an ongoing collaboration between academics, librarians, publishers, editors, and software developers, working together to build alternatives in scholarly publishing. The project has developed a suite of open source software that significantly reduces the time and expense required for producing academic journals and conferences, and facilitates making research results freely available through open access. This article examines the history of the project, provides an overview of its open source software, discusses the growing community participating in the project, and considers its future directions. 相似文献

This study challenges the traditional view that organizational culture, relationships, and communication activities precede or produce the outcomes of job satisfaction and perceived organizational effectiveness. Specifically, the study (a) empirically examines job satisfaction and perceived effectiveness for their potential as important explanatory processes for the outcomes of organizational culture, relationships, and information receiving and sending, and (b) empirically compares the traditional model with the competing conceptualization. Results of a canonical correlation analysis utilizing 2245 individuals in 21 organizations in various parts of the world indicate that 54.8% of the variance in perceptions of culture, relationships, information receiving, and information sending can be explained by job satisfaction and perceived organizational effectiveness. Results of a nested model comparison of the two models using latent variable path analysis demonstrated that the competing conceptualization is a significantly better fit to the data than the traditional view. 相似文献

Student interest,empowerment and motivation 总被引:2,自引:0,他引:2
Literature from the fields of educational psychology and instructional communication are reviewed to lend insight into the relationship between interest and empowerment. Theoretical similarities of these two constructs are highlighted in an attempt to argue for concept isomorphism. Results obtained from Pearson's Correlation's, factor‐analytic techniques, and relationships with other known constructs (motivation) suggest that the Learner Empowerment Scale is a valid and reliable means for the assessment of Student Interest. 相似文献

This study examines some of the reconciliation and repair/maintenance strategies in the relational communication literature. These strategies were compared with Bell and Daly's (1984) affinity‐seeking strategies. It was concluded that Bell and Daly's strategies could identify many of the same relational strategies with less contextual confusion. It is argued that affiliation strategies represent a true multiphasic relational communication typology that applies to the range of repair/reconciliation contexts. The study then looks at the degree to which assertiveness, and responsiveness predicts the use/non‐use of affinity seeking strategies in the context of relational repair. The study indicates that self perceived assertiveness and responsive play a role in strategy selection as well. Finally, how others are perceived in terms of assertiveness and responsiveness was found to predict the types of strategies used and not used in relational repair contexts. 相似文献

Many state and federal governments have mandated in such documents as the National Science Education Standards that inquiry strategies should be the focus of the teaching of science within school classrooms. The difficult part for success is changing teacher practices from perceived traditional ways of teaching to more inquiry‐based approaches. Arguments are often made about the effectiveness of these traditional strategies. The purpose of this study was to compare the effectiveness of the inquiry‐based approach known as the Science Writing Heuristic approach as a treatment to traditional teaching practices on students' post‐test scores in relation to students' achievement level and teacher's implementation of the approach. A mixed‐method research approach was used to analyze the teacher observational data and students' test results. The major findings of this study are that the quality of the implementation does have an impact on student performance on post‐test scores and that high‐quality implementation of the Science Writing Heuristic approach has significant advantages in closing the achievement gap within science classrooms. 相似文献

Previous empirical studies using multiple‐choice procedures have suggested that there are misconceptions about the scale of astronomical distances. The present study provides a quantitative estimate of the nature of this misconception among US university students by asking them, in an open‐ended response format, to make estimates of the distances from the Earth to the Moon, to the Sun, to the nearest star, and to the nearest galaxy. The 83 participants were asked to give their estimates on a scale with the Earth the size of a baseball, using a familiar local landmark for its position, and asked to indicate the appropriate location of the other astronomical objects on this scale. These psychological estimates were then compared to the actual physical distances. The data showed that while there is great variation, a general pattern emerged that US undergraduate participants overestimated the distance from the Earth to the Moon, moderately underestimated the distance from the Earth to the Sun, and dramatically underestimated the distances to the nearest star and to the nearest galaxy. The results suggest that these distance misconceptions should receive direct instructional attention in science courses. 相似文献

I examine the influence of dual enrollment, a program that allows students to take college courses and earn college credits while in high school, on academic performance and college readiness. Advocates consider dual enrollment as a way to transition high school students into college, and they further claim that these programs benefit students from low socioeconomic status (SES). However, few researchers examine the impact of dual enrollment on academic performance and college readiness, in particular, whether SES differences exist in the impact of dual enrollment. Even fewer researchers consider the extent to which improved access to dual enrollment reduces SES gaps in academic performance and college readiness. I find that participation in dual enrollment increases first-year GPA and decreases the likelihood for remediation. I conduct sensitivity analysis and find that results are resilient to large unobserved confounders that could affect both selection to dual enrollment and the outcome. Moreover, I find that low-SES students benefit from dual enrollment as much as high-SES students. Finally, I find that differences in program participation account for little of the SES gap in GPA and remediation. 相似文献
