This study explores science communication on Twitter by investigating a sample of tweets referring to academic papers in five different scientific fields. The specifications of science communicators on Twitter, the characteristics of those who initiate actions (by tweeting), the extent and quality of reactions (retweeting), individual and group interactions, and the distribution of tweets across types of engagement in the process of science communication (i.e., dissemination, consultation, and evaluation) were explored. A broad array of actors is involved in the communication of science on Twitter, with individual citizens and individual researchers playing an important role. In principle, this is promising for creating direct interaction, which can be difficult through more traditional mass media. The vast majority of communication activities regarding academic papers is undigested dissemination with almost no sign of debate, contestation, or collective reflection. Another general finding of this study is that bot accounts play a major role in the science communication landscape on Twitter. 相似文献

The educational experiences of Southeast Asian Americans, particularly Cambodian Americans, Hmong Americans, Laotian Americans, and Vietnamese Americans, are characterized by numerous challenges, which can be attributed to their migration history, socioeconomic status, and English proficiency. By the end of 11th grade, a high percentage of Southeast Asian American students are not college ready. The educational challenges of Southeast Asian Americans have been overshadowed by the model minority stereotype. Educational policies targeting issues affecting the education of Southeast Asian Americans and teacher preparations that focus on getting Southeast Asian American students to be college ready could help change the educational story of this population. 相似文献

A critically transformative education continues to be at the center of Tucson Unified School District's (TUSD) equity and academic excellence mission. Through the use of the Social Transformation paradigm and the lesson learned from the implementation of the Critically Compassionate Intellectualism Model, TUSD once again created a cutting edge transformative, cultural, ethnic, multicultural, equity-based curricula that seeks to stimulate the blossoming intellectual capacities of our students. It presents the opportunity to build foundations and structures of collective and individual agency. Along the lines of agency, it promotes what is called barriorganic intellectualism and the nurturing of gardens of intellectualism (jardines del intelectualismo) that provide opportunities for both the academic and personal transformation of our students. 相似文献

The special issue aims at exploring, with an economic perspective, the interconnections between cultural participation, in all its expressions, and tourism organization and patterns with the purpose of understanding economic effects, emerging trends and policy implications. The expanding notion of the cultural consumption of tourists makes the definition of cultural tourism increasingly elusive. Empirical investigations of the relationships between cultural participation and cultural heritage and tourism offer interesting hints in many directions. This introduction briefly overviews the premise of this special issue, the literature and the several perspectives taken by the included articles. Aside from their cultural topics—general, intangible or temporary—these essays all tackle some important economic dimensions of tourism. We encourage cultural economists to invest more in these fascinating areas as more than just intellectual tourists. 相似文献

Considering the growth in research, examining the development of mainstream sport athletes over the past two decades, studies examining development of athletes with disabilities have been surprisingly limited. While similarities in developmental trajectories between the two cohorts may exist regarding factors such as the value of practice, which tend to be universal regardless of context, disability-related issues (e.g. whether the disability was congenital or acquired) may influence the course of development, affecting variables such as starting age, training and developmental milestones. Fifty-two male and female athletes training with the Wheelchair Basketball Canada National Academy provided detailed training histories. Athletes illustrated similar developmental patterns (e.g. milestones, training adjustments) as they progressed through their sporting career. However, athletes with congenital disabilities started participation in wheelchair basketball and unorganised practice at significantly younger ages (t49?=??4.35, p?<?.001, d =?1.32; t49?=??3.49, p?<?.001, d =?1.03, respectively). While athletes with congenital disabilities continued to reach a majority of the sporting milestones at younger ages, athletes with acquired disabilities were able to reach late career milestones (e.g. national debuts) at similar ages. Athletes’ disability severity did not influence their progress through the developmental milestones and time devoted to training throughout their sporting career. Future work may consider examining developmental trajectories and training histories of athletes in various parasports to extend our understanding of their development and skill acquisition. 相似文献
