To determine the energy cost of low impact aerobic dance while varying arm movement height and the use of hand weights, 10 adults volunteered to participate in four choreographed trials. All trials consisted of identical leg movements. Arm movements, however, were performed above shoulder level both with and without 0.9-kg hand weights and below shoulder level both with and without 0.9-kg hand weights. Open circuit spirometry was employed throughout the 10-min videotape guided trials, and heart rate was measured by telemetry. Neither the use of hand weights nor the change in arm position height significantly altered the energy cost of low impact aerobic dance. However, heart rate responses were significantly different. Caution should be observed by aerobics instructors and participants as to the use of heart rate as an indicator of intensity for low impact aerobic dance. 相似文献

Rather than using literary texts to evidence an analytic argument, within this piece we read Julia McNair Wright's (US, 1840–1902), Sidonie-Gabrielle Colette's (France, 1873–1954), and Willa Cather's (US, 1873–1947) texts through theoretical lenses that expose their educational meaning and value and that create conversation among them concerning girls’ and women's educations. While we do not claim that one can generalize these women's works and lessons to every life, we contend that these women and the literary products they created offer girls and women powerful lessons about resistance, subversion, and nurturing one's intellect, lessons that in some ways transcend class and race in particular. First, we define and explain Bruner's concept of the more using Rosenblatt, Gallagher, and Gardner's theories and findings to illuminate his concept. Next, we identify and examine three themes that emerge across these authors’ texts—subverting through the everyday, becoming one's own steward, and moving from survival to self-actualization. Establishing these themes first in Wright's texts, we then use them to frame Colette's and Cather's fiction and support these themes by focusing on one lesson that emerges from each author's work(s). Finally, we ask what one might learn about educating girls and women from these texts and others whose educative meaning and value remain hidden. 相似文献

Administrative rhetoric: An undemocratic response to protest 总被引:1,自引:0,他引:1
Theodore Otto Windt Jr. 《Communication quarterly》2013,61(3):245-250
Much of the criticism of protest rhetoric has centered on the protestors themselves. This essay focuses on administrators, particularly those at the University of California at Berkeley, and the rhetoric they used in response to protest. It outlines the major lines of argument that administrators traditionally use. 相似文献

The purpose of this study was to determine the impact of technology use and teacher professional development on students’ mathematics academic achievement. The U.S. Department of Education National Assessment of Educational Progress (NAEP) published results for mathematics assessments for Grade 4 from the years 2005–2015 served as the dependent variable. Specific items related to technology use and professional development selected from both student and mathematics teacher questionnaires served as the independent variables. The Technological Pedagogical and Content Knowledge (TPACK) was used as a framework to guide this research. Data analyses revealed significant differences across multiple variables and multiple years. 相似文献

Determination of amyloid β (Aβ) isoforms and in particular the proportion of the Aβ 1-42 isoform in cerebrospinal fluid (CSF) of patients suspected of Alzheimer's disease might help in early diagnosis and treatment of that illness. Due to the low concentration of Aβ peptides in biological fluids, a preconcentration step prior to the detection step is often necessary. This study utilized on-chip immunoprecipitation, known as micro-immunoprecipitation (μIP). The technique uses an immunosorbent (IS) consisting of magnetic beads coated with specific anti-Aβ antibodies organized into an affinity microcolumn by a magnetic field. Our goal was to thoroughly describe the critical steps in developing the IS, such as selecting the proper beads and anti-Aβ antibodies, as well as optimizing the immobilization technique and μIP protocol. The latter includes selecting optimal elution conditions. Furthermore, we demonstrate the efficiency of anti-Aβ IS for μIP and specific capture of 5 Aβ peptides under optimized conditions using various subsequent analytical methods, including matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF-MS), capillary electrophoresis, microchip electrophoresis, and immunoblotting. Synthetic Aβ peptides samples prepared in buffer and spiked in human CSF were analyzed. Finally, on-chip immunoprecipitation of Aβ peptides in human CSF sample was performed. 相似文献

Master data management (MDM) is a topic of increasing prominence both in the scientific and in the practitioners’ information systems (IS) community. As a prerequisite for meeting strategic business requirements, such as compliance with regulations, business integration, or integrated customer management, MDM comprises numerous activities. One of the central activities is designing and maintaining the master data architecture. Interestingly, though, the scientific community has remained almost silent with regard to the question as to how companies should proceed when designing the master data architecture. In order to shed light on this unexplored topic, the paper at hand presents the findings of a case study at Bosch Group. The case study shows that designing the master data architecture is a multidimensional task which requires balancing the interests of various organizational stakeholders, managing an array of technical opportunities, and meeting requirements of numerous master data classes. Also, the case study suggests that taking advantage of architectural design patterns may be an appropriate way to adequately address the complexity of the task. 相似文献
