Now You See Me – Now You Don't: Journalists’ Experiences With Surveillance     

Anthony Mills 《Journalism Practice》2019,13(6):690-707

If democracy is a platform for many voices, and the voices of the many, journalists serve democracy by bringing these voices to the forefront of governance by asking difficult questions to those in power. It can be argued that journalists engage in the broader form of surveillance of power from below, or sousveillance [Mann, Steve, and Joseph Ferenbok. 2013. “New media and the power politics of sousveillance in a surveillance-dominated world.” Surveillance and Society 11 (1-2): 18–34.], which aims towards a form of relative equilibrium. In democracies, the institutional system of checks and balances forms the basis on which journalism pursues its watchdog function. This paper explores the experiences of journalists with surveillance and their impact on journalists’ sense of freedom to fulfil their watchdog role. The paper contributes to increasing research interest in “journalism after Snowden” by addressing the intangible conditions under which journalists may or should work, and ultimately also how widely accepted standards of democratic liberties are challenged.  相似文献   

Professional Development for School Library Media Professionals: Elements for Success     

Carol A Brown  Lana Kaye Dotson  Elaine Yontz 《TechTrends》2011,55(4):56-62

The American Association for School Librarians suggests an important mission for school librarians is to ensure personal growth through ongoing exposure to conferences, journal articles, webinars, presentations, and membership in professional organizations. As professional educators, School Librarians should exemplify the vision for being life-long learners. Methods and means to grow in the profession should be evaluated and examined for elements that lead to success in growth and maturity as professionals in school library media. This article investigates the attributes of successful professional development experiences which include learning environment, characteristics of learners, methodologies, and instructional design of staff development workshops.  相似文献   

Mean-square integral input-to-state stability of nonlinear impulsive semi-Markov jump delay systems     

Yu Lin  Yu Zhang  Anthony Bloch 《Journal of The Franklin Institute》2021,358(4):2453-2481

In this paper, the problem of mean-square integral input-to-state stability of nonlinear impulsive semi-Markov jump delay systems is investigated. By using stochastic Lyapunov functions together with Razumikhin technique, some sufficient conditions for mean-square integral input-to-state stability for a class of nonlinear impulsive semi-Markov jump delay systems are developed. In particular, the results obtained generalize and complement some recent literature. Finally, some numerical examples are given to show the effectiveness and advantages of the proposed techniques.  相似文献   

Fusing different information retrieval systems according to query-topics: a study based on correlation in information retrieval systems and TREC topics     

Anthony Bigot  Claude Chrisment  Taoufiq Dkaki  Gilles Hubert  Josiane Mothe 《Information Retrieval》2011,14(6):617-648

To evaluate Information Retrieval Systems on their effectiveness, evaluation programs such as TREC offer a rigorous methodology as well as benchmark collections. Whatever the evaluation collection used, effectiveness is generally considered globally, averaging the results over a set of information needs. As a result, the variability of system performance is hidden as the similarities and differences from one system to another are averaged. Moreover, the topics on which a given system succeeds or fails are left unknown. In this paper we propose an approach based on data analysis methods (correspondence analysis and clustering) to discover correlations between systems and to find trends in topic/system correlations. We show that it is possible to cluster topics and systems according to system performance on these topics, some system clusters being better on some topics. Finally, we propose a new method to consider complementary systems as based on their performances which can be applied for example in the case of repeated queries. We consider the system profile based on the similarity of the set of TREC topics on which systems achieve similar levels of performance. We show that this method is effective when using the TREC ad hoc collection.  相似文献

An emerging community in online mathematics teacher professional development: an interactional perspective     

Matranga  Anthony  Silverman  Jason 《Journal of Mathematics Teacher Education》2022,25(1):63-89

Online collaborative and content-focused professional development (PD) is becoming an increasingly important setting for supporting mathematics teachers’ professional learning. The purpose of this study was to better understand the process by which a community emerges in such a PD setting by examining how the cohesiveness of 21 mathematics teachers’ social network evolves and associated shifts in the quality of mathematics teachers’ mathematical discourse. We employed social network analysis (SNA) to examine the evolving cohesiveness of mathematics teachers’ social network and coding procedures to examine teachers’ mathematical discourse. A key finding was the documentation of an emergent divide between participation in the core and periphery during initial weeks of the PD and then a reduced divide and emergence of a social network that resembles a community. We argue that the instructor’s pattern of participation that included distributing their interactions across the subgroups while sending a common message regarding expectations for mathematical discourse in the PD may have contributed to the community formation process. We propose the Interaction Assessment Model, which outlines an approach for PD facilitators to use SNA as a feedback mechanism to differentiate facilitation of online collaborative and content-focused PD and build online communities.

Experimental Evaluation of the Value Added by Raising a Reader and Supplemental Parent Training in Shared Reading     

Jason L. Anthony  Jeffrey M. Williams  Zhoe Zhang  Susan H. Landry  Martha J. Dunkelberger 《Early education and development》2014,25(4):493-514

Research Findings: In an effort toward developing a comprehensive, effective, scalable, and sustainable early childhood education program for at-risk populations, we conducted an experimental evaluation of the value added by 2 family involvement programs to the Texas Early Education Model (TEEM). A total of 91 preschool classrooms that served minority populations of low socioeconomic status were randomly assigned to TEEM, TEEM plus Raising a Reader (RAR), or TEEM plus RAR augmented by Family Nights. Assessments of oral language and print knowledge were completed by more than 500 children at the beginning and end of the school year. Multilevel analyses of covariance controlled for classroom nesting and individual differences in age, ethnicity, and pretest scores. Although RAR alone demonstrated no added value, augmentation of RAR with Family Nights demonstrated significant impacts on measures of oral language (ts = 1.81–2.51, .05 < ps < .01) and print knowledge (t = 2.39, p < .01). Practice or Policy: Thus, parent training in shared reading practices appears to be necessary for children to benefit from programs that enrich the home literacy environment. That the combined program particularly benefited children who started preschool lagging behind in school readiness (ts = 1.64–2.49, ps < .05) suggests that this comprehensive model offers hope for closing the achievement gap.  相似文献   

Concurrent object-discrimination learning in rats     

Anthony C. Santucci  F. Robert Treichler 《Learning & behavior》1990,18(3):295-301

Investigations employing primates have sometimes used tests of concurrent object-discrimination as indexes of multiproblem memory in comparative studies of neuropathological impairment. The present investigation was an attempt to employ a comparable test procedure with rats. Data from two experiments indicated that rats could indeed be trained on a concurrent object-discrimination task. Furthermore, results from the second experiment indicated that these performances and brightness discriminations shared the property of disruption by posterior decortication. Implications for the neuropsychology of learning and memory are discussed.  相似文献
