Past research concerning the theoretical framework of Resistance Performance (RP) has been based on observations of liberal organizations and activists. In the following essay, we engage in a qualitative content analysis of alternative media utilized by conservative “Tea Party” activists to build on the concept of RP. Overall, we discovered that the dominant theme found in much of the content focuses on “purity,” which is considerably different from past RP research that found broad themes of “human rights,” “democracy,” “be the media,” and “principles of unity” embedded within liberal alternative media content. We conclude that the theme of “purity” gives rise to narrowmobilization, which constructs very focused protest communities within right-leaning politics.  相似文献

This study examined the links among adolescents' representations of their relationships with parents, friends, and romantic partners. Sixty-eight adolescents were interviewed three times to assess their working models for each of these types of relationships. Working models of friendships were related to working models of relationships with parents and romantic partners. Working models of relationships with parents and romantic partners were inconsistently related. A similar pattern of results was obtained for self-report measures of relational styles for the three types of relationships. Perceived experiences were also related. Specifically, support in relationships with parents tended to be related to support in romantic relationships and friendships, but the latter two were unrelated. On the other hand, self and other controlling behaviors in friendships were related to corresponding behaviors in romantic relationships. Negative interactions in the three types of relationships also tended to be related. Taken together, the findings indicate that the representations of the three types of relationships are distinct, yet related. Discussion focuses on the nature of the links among the three.  相似文献

Societal response to climate change has been inadequate. A perception that the issue is both physically and temporally remote may reduce concern; concern may also be affected by the political polarization surrounding the issue in the USA. A feeling of connection to nature or to animals may increase personal relevance, and a supportive social context may counteract political tensions. Zoos may provide opportunities for both sense of connection and social support. We surveyed over 7000 zoo and aquarium visitors to examine the ways in which a feeling of personal connection among zoo visitors may encourage concern about climate change. Results show that feeling connected to animals at the zoo is significantly associated with cognitive and emotional responses to climate change, as well as with other social groupings and social responses. Overall, the zoo seems to present a supportive social context for considering the topic.  相似文献

This study investigated the impact of an open inquiry experience on elementary science methods students’ understanding of celestial motion as well as the methods developed by students to answer their own research questions. Pre/post interviews and assessments were used to measure change in participants’ understanding (N = 18). A qualitative approach was used to describe the nature of each participant’s investigation through an analysis of their science journal and poster presentations. A comparison of participants’ inquiry projects with the change in their understanding revealed that while most participants improved in both their area of inquiry and beyond, elementary science methods students may need more guidance to reach a full scientific understanding across all aspects of celestial motion.  相似文献

As the last century closed, and a bright new millennium dawned, the concept of ‘student voice’ within education emerged as something to be ‘identified’ and ‘captured’. In effect, it became reified and driven by a raft of government and institutional policies and strategic initiatives; initially within the compulsory sector, but soon followed by the post-compulsory sector as the 2000s moved on. In an increasingly quasi-consumerist environment, a mechanism had emerged with potential to ‘measure’ student satisfaction. Institutions quickly took up the ‘call to arms’, assigning responsibilities to ensure there was evidence of ‘student voice’ engagement; but there was no conversation with the ‘students’ about how this was experienced by them. This concept had become a ‘portmanteau’ term; a ‘catch all’ competing between two narratives—student voice as democratic and transformational; and student voice as ‘policy’ and strategic initiative. Formal research that could contribute to this discussion has been sparse and this paper takes a critical stance to the literature and policy, exploring the current status of student voice and proposing a research focus that has the potential to involve students in a discussion about how their voice is heard, and for what purpose.  相似文献

Amplification of multiple unique genetic targets using the polymerase chain reaction (PCR) is commonly required in molecular biology laboratories. Such reactions are typically performed either serially or by multiplex PCR. Serial reactions are time consuming, and multiplex PCR, while powerful and widely used, can be prone to amplification bias, PCR drift, and primer-primer interactions. We present a new thermocycling method, termed thermal multiplexing, in which a single heat source is uniformly distributed and selectively modulated for independent temperature control of an array of PCR reactions. Thermal multiplexing allows amplification of multiple targets simultaneously—each reaction segregated and performed at optimal conditions. We demonstrate the method using a microfluidic system consisting of an infrared laser thermocycler, a polymer microchip featuring 1 μl, oil-encapsulated reactions, and closed-loop pulse-width modulation control. Heat transfer modeling is used to characterize thermal performance limitations of the system. We validate the model and perform two reactions simultaneously with widely varying annealing temperatures (48 °C and 68 °C), demonstrating excellent amplification. In addition, to demonstrate microfluidic infrared PCR using clinical specimens, we successfully amplified and detected both influenza A and B from human nasopharyngeal swabs. Thermal multiplexing is scalable and applicable to challenges such as pathogen detection where patients presenting non-specific symptoms need to be efficiently screened across a viral or bacterial panel.  相似文献

The Special Collections Research Center at Johns Hopkins University received a Council on Library and Information Resources Hidden Collections grant from March 2013 to March 2014 for processing the archives of the Roland Park Company. The grant included partnerships between the Archives and Technical Services to create a Best Practices for EAC-CPF records, as well as a local high school history class to complete the required research. Rather than simplify International Standard Archival Authority Record For Corporate Bodies, Persons and Families and EAC-CPF for the students, project staff distilled them into discrete, easy-to-understand tasks that allowed for the production of controlled data in a high school environment.  相似文献

In post-secondary education, there is a widely-held belief in a “gold standard” for evaluative studies of curricular innovations. In this context, “appropriate” assessment is understood to refer to experimental designs and statistically significant differences in group outcomes. Yet in our evaluative study of a medical undergraduate program, we did not find these concepts to be particularly applicable. Based on our experience, we now feel that it is appropriate to assemble an eclectic mix of scientific findings, show how they have been used for program improvement, and articulate the program’s theoretical rationale and social significance. In the absence of statistically significant differences, this comprehensive argument can be used to justify the deployment of curricular innovations. The same may be true of other educational programs that target hard-to-measure changes in affective domains.  相似文献

Large cohorts (>200 students) are an ever-increasing presence in the UK higher education (HE) sector. Providing excellent teaching and learning to these large classes is an ongoing challenge for teaching faculty, a challenge intensified when the cohort comprises 85% non-native English speakers. This paper presents the findings of a project to supplement face-to-face lectures on a large campus-based taught MSc programme with a set of rich-media materials. These resources consisted of audio podcasts, audio-narrated slides, short video segments and full-video lecture capture. The aim of the study was to examine student usage of, and preference for, these different rich-media materials. Key findings are that students valued most highly the full-video lecture capture followed by the audio-narrated slides, using the materials primarily to consolidate their understanding and as revision aids. Students also emphasised the central importance of the face-to-face lecture – viewing the rich-media materials as complementary to, rather than as a replacement for the traditional lecture. Nor did the majority of students see the provision of videoed lectures as a reason for non-attendance at lectures. The findings of this study provide confirmatory evidence of the ongoing importance of the traditional lecture in large cohort HE teaching together with an acknowledgement of the benefits that rich-media materials can bring to the student learning experience.  相似文献

While a number of scholars have discussed the pervasiveness of the conceptualization of students as customers, to date there has been limited reliable research examining the extent to which students actually view themselves as customers. Using a survey that was administered to a census of entering first-year students at a large public research university (59.8% response rate), this study shows that students do not agree with many of the educational beliefs and planned behaviors associated with a customer orientation. Results of exploratory factor analysis suggested only 28.9% of respondents expressed a customer orientation. These results show that contrary to what has become common sense in postsecondary education, most students at this public university do not express a customer orientation towards their education. Such findings should make scholars and practitioners rethink some of their embedded assumptions with regards to the goals, motivations, and general educational orientations of today's college students.  相似文献
