Adapted Verbal Feedback,Instructor Interaction and Student Emotions in the Landscape Architecture Studio 下载免费PDF全文
In light of concerns with architectural students’ emotional jeopardy during traditional desk and final‐jury critiques, the authors pursue alternative approaches intended to provide more supportive and mentoring verbal assessment in landscape architecture studios. In addition to traditional studio‐based critiques throughout a semester, we provide privately held, one‐on‐ one feedback at the semester's close that follows a mentor–trainee model of purposeful interface and a vision of where the student is going. This article reports 82 landscape architecture students’ experience of this adapted verbal feedback. The findings suggest an overwhelming positive student experience, and we conclude that these sessions help balance the emotional challenge of architectural study with nurturing support. Furthermore, the students’ positivity was not influenced by their experiences in the previous class. We therefore conclude that the adapted feedback sessions provide appropriate closure, even when (perhaps particularly when) a student has had a negative emotional experience during the class. 相似文献

To reduce sensory uncertainty, humans combine cues from multiple senses. However, in everyday life, many co‐occurring cues are irrelevant to the task at hand. How do humans know which cues to ignore? And does this ability change with development? This study shows the ability to ignore cross‐modal irrelevant information develops late in childhood. Participants performed a sound discrimination task, with or without an irrelevant visual flash, presented synchronously in front of them. Adults ignored the irrelevant visual information, while 7‐ to 10‐year‐olds' responses were biased toward the flash location. The findings show that acquiring mature cue combination mechanisms is a multifaceted process that includes learning to ignore irrelevant cues, as well as to optimally combine relevant cues. 相似文献

In vitro assays of platelet function and coagulation are typically performed in the presence of an anticoagulant. The divalent cation chelator sodium citrate is among the most common because its effect on coagulation is reversible upon reintroduction of divalent cations. Adding divalent cations into citrated blood by batch mixing leads to platelet activation and initiation of coagulation after several minutes, thus limiting the time blood can be used before spontaneously clotting. In this work, we describe a herringbone microfluidic mixer to continuously introduce divalent cations into citrated blood. The mixing ratio, defined as the ratio of the volumetric flow rates of citrated blood and recalcification buffer, can be adjusted by changing the relative inlet pressures of these two solutions. This feature is useful in whole blood assays in order to account for differences in hematocrit, and thus viscosity. The recalcification process in the herringbone mixer does not activate platelets. The advantage of this continuous mixing approach is demonstrated in microfluidic vascular injury model in which platelets and fibrin accumulate on a collagen-tissue factor surface under flow. Continuous recalcification with the herringbone mixer allowed for flow assay times of up to 30 min, more than three times longer than the time achieved by batch recalcification. This continuous mixer allows for measurements of thrombus formation, remodeling, and fibrinolysis in vitro over time scales that are relevant to these physiological processes. 相似文献

In 2010, the Association for the Advancement of Sustainability in Higher Education released, “Sustainability curriculum in higher education: A call to action,” encouraging infusion of sustainability topics into universities' teaching and research. Since then, academic programs and research related to social, economic, and environmental sustainability have enriched university curricula. An exploratory study was conducted to determine the position and engagements of academic libraries and information science schools in their contributions to scholarly sustainability activities and curricular initiatives. This article presents the results of the study which reveals a number of engagements by library professionals in the areas of sustainability, such as increasing open access to research, building sustainability-related collections and research guides, and incorporating sustainability content into information literacy. While academic libraries and information science schools are engaged in a broad spectrum of initiatives that support their institutions' sustainability research and curricular functions, this study indicates that such activities require a more targeted approach. 相似文献

Understanding theory–practice relationships in pre-service teacher education is an enduring concern for many teacher educators. Drawing on data from an investigation into the theory–practice nexus in an outdoor education teacher education programme, this article examines pedagogical approaches to exploring theory and practice with pre-service teachers. The investigation, a qualitative case study, examined the views of the programme’s teacher educators (authors) using an analytical lens informed by two similar theoretical models.
The article focuses on elements that were found to be central to pedagogical approaches within the programme: self-awareness, experience, reflexivity, and a “community of learners.” While the approaches represent a departure from “theory application” and “theory–practice integration” approaches, and a move towards praxis development, the study highlighted challenges and issues including the need for teacher educators to scrutinise theory–practice relationships in their own teaching and discourse. Implications and possibilities for future practice are considered. 相似文献

In 2012, an academic health sciences library serving a large research university and medical center introduced synchronous online training for a diverse group of users, including clinicians, researchers, faculty, and distance students. Participants in these “Express Training” classes completed two surveys to assess their experiences. Survey results indicated classes were well received but revealed some areas for improvement. Included are issues that should be considered when implementing online library instruction to meet the diverse needs of academic health sciences library users. Given the popularity of online training among on-campus and distance users, it will be continued and expanded. 相似文献

In 2010, New York Times photographer Damon Winter sparked controversy when he used an iPhone equipped with the Hipstamatic application to produce heavily filtered, Polaroid-style front-page photographs of U.S. troops in Afghanistan. The debate over whether such images were photojournalism, or merely photographs, was reignited the next year as some of his images were honored in one of the country's most prestigious photojournalism competitions, and the practice of using filter-friendly apps for journalism spread. This article compares professional discourses around such journalistic use of smartphone apps with discourses that developed earlier in the digital era around digital image manipulation in Photoshop, with the goal of proposing ways to interrogate imaging technology controversies yet to come. 相似文献

Both general and domain-specific search engines have adopted query suggestion techniques to help users formulate effective queries. In the specific domain of literature search (e.g., finding academic papers), the initial queries are usually based on a draft paper or abstract, rather than short lists of keywords. In this paper, we investigate phrasal-concept query suggestions for literature search. These suggestions explicitly specify important phrasal concepts related to an initial detailed query. The merits of phrasal-concept query suggestions for this domain are their readability and retrieval effectiveness: (1) phrasal concepts are natural for academic authors because of their frequent use of terminology and subject-specific phrases and (2) academic papers describe their key ideas via these subject-specific phrases, and thus phrasal concepts can be used effectively to find those papers. We propose a novel phrasal-concept query suggestion technique that generates queries by identifying key phrasal-concepts from pseudo-labeled documents and combines them with related phrases. Our proposed technique is evaluated in terms of both user preference and retrieval effectiveness. We conduct user experiments to verify a preference for our approach, in comparison to baseline query suggestion methods, and demonstrate the effectiveness of the technique with retrieval experiments. 相似文献

We examined the effects of concomitant increases in crank rate and power output on incremental arm crank ergometry. Ten healthy males undertook three incremental upper body exercise tests to volitional exhaustion. The first test determined peak minute power. The subsequent tests involved arm cranking at an initial workload of 40% peak minute power with further increases of 10% peak minute power every 2 min. One involved a constant crank rate of 70 rev · min(-1), the other an initial crank rate of 50 rev · min(-1) increasing by 10 rev · min(-1) every 2 min. Fingertip capillary blood samples were analysed for blood lactate at rest and exhaustion. Local (working muscles) and cardiorespiratory ratings of perceived exertion (RPE) were recorded at the end of each exercise stage. Heart rate and expired gas were monitored continuously. No differences were observed in peak physiological responses or peak minute power achieved during either protocol. Blood lactate concentration tended to be greater for the constant crank rate protocol (P = 0.06). Test duration was shorter for the increasing than for the constant crank rate protocol. The relationship between local RPE and heart rate differed between tests. The results of this study show that increasing cadence during incremental arm crank ergometry provides a valid assessment of peak responses over a shorter duration but alters the heart rate-local RPE relationship. 相似文献
