Regulating film,regulating emotion: the emotional history of public opinion     

Jennifer Petersen 《Critical Studies in Media Communication》2016,33(4):324-336

The article argues that the legal about face in 1950s law in which film was granted First Amendment protection was driven in part by a change in the “emotional regimes” of US democracy, or emotions/performances of emotion that are part of legitimate political culture. The legal understanding of how film does or does not contribute to democratic political culture tracks historical shifts in these emotional regimes. In the teens, elites feared the activation of the masses, as crowds, in political uprisings. By 1950, elite fears had turned to passive audiences, “narcotized” masses that might easily be seduced by totalitarian demagogues.  相似文献

Models of understanding: historical constructions of breast cancer in medicine and public health     

Jennifer Petersen 《International journal of qualitative studies in education》2013,26(4):537-555

The era of technical and scientific progress ushered in with the twentieth century brought new medical knowledge such as the Halstead ‘radical’ mastectomy, which promised a cure for breast cancer. These advances in medical knowledge were premised on an epidemiological model of disease, which shaped the treatment and public understanding of breast cancer through most of the twentieth century—to be replaced by a systemic model of breast cancer in the later years of the century. This article traces how this shift was both influenced by and influential on public understandings of medicine and disease. The author argues that, while the epidemiological model of disease shaped treatment options and public health campaigns through most of the century, current treatment regimes and health campaigns are shifting to reflect changes in the underlying model of disease (toward a systemic model).  相似文献   

Minimum reading fluency necessary for comprehension among second‐grade students

The current study examined the relationship between oral reading fluency (ORF) and reading comprehension for students in second grade. A total of 84 participants were randomly assigned to one of four conditions that involved reading a grade‐appropriate passage with either 0%, 10%, 20%, or 30% scrambled words and answering subsequent comprehension questions. The correlation coefficient between ORF and the number of comprehension questions correctly answered was r = .54. Receiver operating characteristics were then used to empirically derive a minimum ORF score necessary for comprehension, indicating that when these students read 63 words correct per minute they successfully comprehended what they read. Finally, the diagnostic accuracy of the derived criterion of 63 words read correctly per minute was tested and resulted in overall correct classification of .80. © 2010 Wiley Periodicals, Inc.  相似文献   

Using an Informal Cardiovascular System Activity to Study the Effectiveness of Science Education in Unexpected Places     

Elyssa Lynne Monzack  Greta M. Zenner Petersen 《Research in Science Education》2011,41(4):453-460

Venues for informal science education are usually those sought out by people who are specifically looking for an educational experience. Whether planning a trip to a museum or choosing a television program, these individuals are actively seeking an informal educational experience; they are a self-selected group. This paper investigates whether members of the public will respond to an informal science activity that is placed in a location where learning about science would be unexpected. This project developed and used an activity about the cardiovascular system in which participants were able to walk the path of blood flow through the heart, body, and lungs. This activity was tested in two types of settings: where science was either expected or unexpected. A non-traditional assessment method was used to evaluate the effectiveness of the activity in the unexpected versus the expected settings. Ultimately, the activity was found to be equally effective in both settings, providing evidence for success in bringing informal science education to the general population in non-traditional venues.  相似文献   

Informal Science Education: A Practicum for Graduate Students     

Wendy C. Crone  Sharon L. Dunwoody  Raelyn K. Rediske  Steven A. Ackerman  Greta M. Zenner Petersen  Ronald A. Yaros 《Innovative Higher Education》2011,36(5):291-304

We present results from a course, “Informal Science Education for Scientists: A Practicum,” co-taught to graduate students in STEM-related fields by a scientist/engineer and a social scientist/humanist. This course provides a structured framework and experiential learning about informal science education during a semester-long experience. The data collected across six years of the course (11 ≤ n ≤ 16 for each) provide strong evidence that the course has been effective in encouraging graduate students in STEM-related fields to feel more skilled at and confident with informal science education. Details are provided as to how manipulation of the course structure (i.e. making it project-based, emphasizing understanding audiences, stressing the iterative nature of design, and increasing evaluation research training) influenced the student outcomes.  相似文献   

Comparison of Hualapai school children to national norms on measures of receptive vocabulary and verbal ability     

James N. Wolfe  Neil H. Schwartz  Jerry D. Petersen 《Psychology in the schools》1996,33(3):245-250

Performance differences on receptive vocabulary and general verbal reasoning ability of Hualapai Indians as compared to national norms were investigated. The Peabody Picture Vocabulary Test Revised and the Verbal portion of the Cognitive Abilities Test, Form 4 were administered to 206 Hualapai Indian children ranging in age from 5 years, 3 months to 15 years, 7 months. Their performance was compared at each grade level to the national norms for these measures. Results indicated that Hualapai children score significantly lower on both measures of verbal ability when compared to national samples. Results provide a long-needed archival record of the English language proficiency of the Hualapai, and support the notion of homogeneity of English language facility across American Indian tribes. Contributing factors to Hualapai and other Native American populations' weaker performance on measures of verbal ability are discussed.  相似文献   

Shape optimization of golf clubface using finite element impact models     

Willem Petersen  John McPhee 《Sports Engineering》2009,12(2):77-85

To model the impact dynamics of a golf drive, finite element (FE) models of the ball and the clubhead are created and combined to simulate the collision of the two bodies. A three-piece golf ball is modelled using only solid elements, while the clubhead is modelled using solid elements for the crucial area of the impact, i.e. the clubface, and using shell elements for the rest of the clubhead to improve the computational efficiency of the simulation. The correct transfer of forces and moments in the transition area between the shell and solid elements is assured by introducing kinematic nodal constraints using rigid elements. The FE model is used to optimize the shape of the clubface in three steps to maximize the launch velocity of the golf ball for central impacts. A final clubface shape is reached and a total improvement of 4.8 m/s over the initial design is obtained. This is a 7% gain in launch velocity, which results in a driving length advantage of approximately 20 m (or 22 yards) until the first contact with the ground. During the optimization process, the mechanical impedances of the two colliding bodies were recorded and compared. It is shown that the optimal clubhead geometry does not agree with the impedance matching theory by comparing the optimization results to those obtained from a simple lumped parameter model.  相似文献
