Topological and non-topological solitons of nonlinear Klein-Gordon equations by He's semi-inverse variational principle     

Ryan Sassaman  Anjan Biswas 《Journal of The Franklin Institute》2010,347(7):1148-7047

This paper studies the topological as well as the non-topological solitons due to the nonlinear Klein-Gordon equations, in presence of perturbation terms. There are five forms of nonlinearity that will be considered. The He's semi-inverse variational principle will be used to carry out the integration.  相似文献   

一位难以忘怀的女子     

Ryan Sundin  李起 《海外英语》2009,(5):36-38

那是一个充满忧伤的清晨。准备的各种食物的香味通常将标志着某个欢庆的节日或者是亲属的聚会,那时才赶着做这些东西,但这天清晨完全是另一回事。我从床上爬起来,尽最大努力只为面对这一天时,全身强烈地感到一阵未曾有过的寒冷。那是我宁愿很快忘却的一天,但不幸的是,我无法忘却。  相似文献   

It's not all about school: Ways of disrupting pre-service teachers' perceptions of pedagogy and communication     

Mary Ryan  Annah Healy 《Teaching and Teacher Education》2009

Many pre-service teachers enter teacher education with problematic or unexamined assumptions about learners and teaching. This article reports on an authentic learning opportunity offered to 22 pre-service teachers in their first year at university, which attempts to disrupt these perceptions about learning and pedagogy. Using a new application of Butin's conceptual framework we show that during the project these participants developed more complex notions of learners and ways of making meaning. We argue that these ‘real-world’ experiences, when offered before pre-service teachers begin practicum in schools, provide more ‘resources’ to problematise the practices and institutional discourses encountered in schools.  相似文献   

Faculty Hiring at Top-Ranked Higher Education Administration Programs: An Examination Using Social Network Analysis     

David DiRamio  Ryan Theroux  Anthony J. Guarino 《Innovative Higher Education》2009,34(3):149-159

Using network analysis we investigated faculty hiring at 21 U. S. News top-ranked programs in higher education administration. Our research questions were as follows. Do top programs hire from each other? Are faculty from the “outside” finding positions at top programs? Mixed results hint at implications for the “health” of the hiring network. Closed systems in higher education may produce unintended consequences as graduate programs look to expand into new global markets.  相似文献   

Job satisfaction,school rule enforcement,and teacher victimization     

Ryan Kapa  Belinda Gimbert 《School Effectiveness & School Improvement》2018,29(1):150-168

Job satisfaction is an essential component of teacher motivation, performance, and retention. Teacher job satisfaction is primarily affected by workplace conditions. This paper analyzes data from over 37,000 public school teachers from the 2011–2012 Schools and Staffing Survey. Hierarchical ordinal logistic regression was utilized to analyze effects of school rule enforcement and teacher victimization on job satisfaction. Findings indicated that teachers who perceived higher enforcement of school rules had higher job satisfaction. In particular, consistent enforcement of rules by school administrators had a significantly greater effect on satisfaction than collegial enforcement of rules. Findings also indicated that teacher victimization has a significantly negative effect on job satisfaction. Consistent enforcement of school rules may reduce instances of student misbehavior and teacher victimization, helping reduce teacher stress and anxiety, leading to greater job satisfaction. Implications for policy and practice are explored, examining what administrators can do to protect teachers and improve satisfaction.  相似文献   

New insight for activity intensity relativity,metabolic expenditure during object projection skill performance     

Ryan S. Sacko  Kerry McIver  Ali Brian  David F. Stodden 《Journal of sports sciences》2018,36(21):2412-2418

This study examined the metabolic cost (METs) of performing object projection skills at three practice trial intervals (6, 12, and 30 seconds). Forty adults (female n = 20) aged 18–30 (M = 23.7 ± 2.9 years) completed three, nine-minute sessions of skill trials performed at 6, 12, and 30 second intervals. Participants performed kicking, throwing and striking trials in a blocked schedule with maximal effort. Average METs during each session were measured using a COSMED K4b2. A three (interval condition) X two (sex) ANOVA was conducted to examine differences in METs across interval conditions and by sex. Results indicated a main effect for interval condition (F(5,114) = 187.02, p < .001, η² = 0.76) with decreased interval times yielding significantly higher METs [30 sec = 3.45, 12 sec = 5.68, 6 sec = 8.21]. A main effect for sex (F(5, 114) = 35.39, p < .001, η² = 0.24) also was found with men demonstrating higher METs across all intervals. At a rate of only two trials/min, participants elicited moderate physical activity, with 12 and 6-second intervals exhibiting vigorous PA. Demonstrating MVPA during the performance of object projection skill performance has potential implications for PA interventions.  相似文献   

Using the Blended Learning Approach in a Quantitative Literacy Course     

Ryan T. Botts  Lori Carter 《PRIMUS》2018,28(3):236-265

The efforts to improve the quantitative reasoning (quantitative literacy) skills of college students in the United States have been gaining momentum in recent years. At the same time, the blended learning approach to course delivery has gained in popularity, promising better learning with flexible modalities and pace. This paper presents the results of an exploratory study that compares student learning outcomes and student attitudes over several semesters of blended versus traditional delivery in the upper-division quantitative literacy course at Point Loma Nazarene University.  相似文献   

How Community Colleges in Texas Prioritize Resources for Latino Men     

Sarah L. Rodriguez  Kelty T. Garbee  Ryan A. Miller  Victor B. Saenz 《Community College Journal of Research & Practice》2018,42(4):229-244

This study explored how administrators at community colleges conceptualized change related to resource allocation and managing competing priorities to support targeted programming for Latino men. The study included the perspectives of 39 administrators from seven community colleges across Texas using concepts associated with institutional change to ground our analysis. Findings revealed that state and national initiatives, particularly those concerned with enhancing success for students of color, influenced how community college administrators approached change on their campuses. In addition, community college institutional mission, leadership, and a desire for data-informed resource management influenced the approach to resource allocation for Latino men.  相似文献   

Adult stakeholder perceptions of 4th grade participation in children’s forest environmental education programming     

Ryan F. Reese 《Environmental Education Research》2018,24(8):1211-1223

An environmental education (EE) consortium located in the pacific northwest United States coalesced an external evaluation team to research its K-5 EE programming. The purpose of this article is to describe one phase of this program evaluation process including the exploration of adult stakeholder perceptions of EE programming accessed by 4th grade children. The author highlights the goals of the consortium and the context for the program evaluation, and the relevant literature addressing adult perspectives on EE is reviewed. The study framing, method, and qualitative results are reported. Findings suggest that adult stakeholders perceived positive impacts from 4th grade participation in EE, though the programming was viewed as being most beneficial to children coming from economically disadvantaged families. Implications for EE practice and research are discussed.  相似文献
