We have developed an approach to collaborative-writing-as-inquiry that we sometimes refer to as ‘between the twos’. Increasingly, we came to understand that the only way to continue in our process was to ‘write to it’; whatever the question, the query or the problem, it was this inducement – ‘write to it’ – that led to new experimentations and the indeterminate rhythms and refrains of the multiple that were often present in the agonistics of our practice. This is how we have been living intra-actively with desire within and against the traditional representations of research and pedagogic practice in higher education in recent years. In offering opportunities for bringing non-totalising modes of sensing to life within Deleuze and Guattari’s experimental and creative originations, and in the multiplicity and the vibrant potentialities of always becoming, we make claims for new, creatively productive writing practices in the university of the future. 相似文献

This study used qualitative and quantitative approaches to evaluate the effectiveness of self‐learning modules (SLMs) developed to facilitate and individualize students' learning of basic medical sciences. Twenty physiology and nineteen microanatomy SLMs were designed with interactive images, animations, narrations, and self‐assessments. Of 41 medical students, 40 students voluntarily completed a questionnaire with open‐ended and closed‐ended items to evaluate students' attitudes and perspectives on the learning value of SLMs. Closed‐ended items were assessed on a five‐point Likert scale (5 = high score) and the data were expressed as mean ± standard deviation. Open‐ended questions further evaluated students' perspectives on the effectiveness of SLMs; student responses to open‐ended questions were analyzed to identify shared patterns or themes in their experience using SLMs. The results of the midterm examination were also analyzed to compare student performance on items related to SLMs and traditional sessions. Students positively evaluated their experience using the SLMs with an overall mean score of 4.25 (SD ± 0.84). Most students (97%) indicated that the SLMs improved understanding and facilitated learning basic science concepts. SLMs were reported to allow learner control, to help in preparation for subsequent in‐class discussion, and to improve understanding and retention. A significant difference in students' performance was observed when comparing SLM‐related items with non‐SLM items in the midterm examination (P < 0.05). In conclusion, the use of SLMs in an integrated basic science curriculum has the potential to individualize the teaching and improve the learning of basic sciences.

Librarians at Louisiana State University Health Sciences Center in Shreveport developed an outreach program for public health workers in north Louisiana. This program provided hands-on training on how to find health information resources on the Web. Several challenges arose during this project. Public health units in the region lacked suitable teaching labs and faced limited travel budgets and tight staffing requirements, which made it impractical for public health workers to travel. One solution to these problems is a portable wireless computer lab that can be set up at each site. The outreach program utilized this approach to present on-site training to public health workers in the region. The paper discusses operational and technical issues encountered in implementing this public health outreach project. 相似文献

This article examines major trends in testing and accountability reform in the United States over the past decade. The review covers the apex and decline of the national experimentation with a range of alternative assessments and the rise of test-based accountability as a central policy initiative. These trends signify that testing has become a widely utilized instrument for educational reform in America. Research on these trends indicates that high stakes testing does motivate teachers and administrators to change their practices, yet the changes they motivate tend to be more superficial adjustments in content coverage and test preparation activities rather than promoting deeper improvements in instructional practice. Further, the information provided by large scale assessments is primarily useful to measure school and system progress, but of more limited utility for instructional guidance. Most problematic is that the high stakes testing system in America has been repeatedly promoted as a substantive reform in itself. However, high stakes testing is a relatively weak intervention because, while it reveals shortcomings, it does not contain the guidance and expertise to inform response. The article concludes with suggestions on how to capitalize on the strengths of high stakes testing while minimizing its shortcomings. 相似文献

Introduction
The determination of lipid biomarkers by capillary sampling may be useful in the screening, diagnosis and/or personal management of hyperlipidemia and cardiovascular risk. It remains unclear whether the use of the Accutrend® Plus system is appropriate. This study aimed to assess its reproducibility, accuracy and concordance for blood lipid profiling in adults.Materials and methods:
Fasting capillary total cholesterol (TC) and triglyceride (TG) concentration on Accutrend® Plus were compared with their venous analogues obtained by a laboratory reference method in sixty-one adults (27 men and 34 women, aged 33.0 years). Supplementary capillary sampling was performed at two consecutive days taking into account macro-nutrient intake.Results:
The day-to-day reproducibility of the Accutrend® Plus system proved to be high for TC (ICC = 0.85, P < 0.001), but moderate for TG (ICC = 0.68, P < 0.001). Strong correlations (r ≥ 0.80, P < 0.001) with the reference method were found for TC and TG. Mean difference (limits of agreement) were: 0.26 mmol/L (−0.95, 1.47) for TC, and −0.16 mmol/L (−1.29, 0.98) for TG. The concordance for subject classification according to the National Cholesterol Education Program (NCEP) guidelines was significant (P < 0.001), with substantial agreement for TC (κw = 0.67), and moderate agreement for TG (κw = 0.50).Conclusions:
Day-to-day reproducibility of the Accutrend® Plus device for TC and TG is not optimal and lacks accuracy when compared to the reference laboratory method. The concordance between both methods for classifying subjects according to the NCEP is inadequate. Accutrend® Plus device should not be interchangeably used as a substitution for the standard laboratory methods in the diagnosis of hyperlipidemia. 相似文献949.

The lack of technologies that combine automated manipulation, sorting, as well as immobilization of single metazoan embryos remains the key obstacle to high-throughput organism-based ecotoxicological analysis and drug screening routines. Noticeably, the major obstacle hampering the automated trapping and arraying of millimetre-sized embryos on chip-based devices is their substantial size and mass, which lead to rapid gravitational-induced sedimentation and strong inertial forces. In this work, we present a comprehensive mechanistic and design rationale for manipulation and passive trapping of individual zebrafish embryos using only hydrodynamic forces. We provide evidence that by employing innovative design features, highly efficient hydrodynamic positioning of large embryos on a chip can be achieved. We also show how computational fluid dynamics-guided design and the Lagrangian particle tracking modeling can be used to optimize the chip performance. Importantly, we show that rapid prototyping and medium scale fabrication of miniaturized devices can be greatly accelerated by combining high-speed laser prototyping with replica moulding in poly(dimethylsiloxane) instead of conventional photolithography techniques. Our work establishes a new paradigm for chip-based manipulation of large multicellular organisms with diameters well above 1 mm and masses often exceeding 1 mg. Passive docking of large embryos is an attractive alternative to provide high level of automation while alleviating potentially deleterious effects associated with the use of active chip actuation. This greatly expands the capabilities of bioanalyses performed on small model organisms and offers numerous and currently inaccessible laboratory automation advantages. 相似文献

The effects of carbohydrate ingestion on the badminton serve after fatiguing exercise 总被引:1,自引:1,他引:0
The badminton serve requires great skill and may be affected by fatigue. The aim of the present study was to determine whether carbohydrate ingestion affects badminton performance. Nine male badminton players (age 25 ± 7 years, mass 80.6 ± 8.0 kg) attended the laboratory on three occasions. The first visit involved an incremental exercise test to exhaustion to determine peak heart rate. Participants were given 1 L of a carbohydrate-electrolyte drink or a matched placebo during the experimental trials. The accuracy of 10 long and 10 short serves was determined before and after exercise. The fatiguing exercise was 33 min in duration (83 ± 10% and 84 ± 8% peak heart rate for the placebo and carbohydrate trial respectively). Capillary blood samples (20 μL) were taken before and after exercise for determination of blood glucose and lactate. There was deterioration in long serve accuracy with fatigue (P = 0.002), which carbohydrate ingestion had a tendency to prevent (P = 0.077). There was no effect of fatigue (P = 0.402) or carbohydrate ingestion (P = 0.109) on short serve accuracy. There was no difference in blood glucose concentration between trials (P = 0.851). Blood lactate concentration was higher during the placebo trial (P = 0.016). These results suggest that only the long serve is influenced by fatigue and carbohydrate had a tendency to prevent the deterioration in performance. 相似文献
