How should we write about markets? What responsibilities does this writing bring upon us? This paper offers an immanent critique of ‘market studies’ scholarship, and through this a call to reflection and reformed action. Turning the intellectual framework of market studies upon itself, we come to see its texts as performative and agential. We discuss these qualities and the associated responsibilities via a reading of literature from the domain of ethnography. An auto-ethnographic sketch of market writing allows us to consider the problematic nature of expertise for market studies scholars and the agency and power of our texts. We find a dual moment of performativity from which our texts emerge more powerful than their authors. On this basis we offer a vision of critical interventions embedded in our texts, underpinned by the intellectual axioms of the market studies programme. 相似文献

BackgroundNew research suggests that the composition (mix) of movement behaviors within a 24-h period may have important implications for health across the lifespan. Consistent with this integrated movement behavior paradigm, a number of countries across the world have developed and released 24-h movement guidelines for specific age groups. The purpose of this systematic review was to examine the associations between the 24-h time-use composition of movement behaviors, or adherence to 24-h movement guidelines, and multiple health indicators across the lifespan.MethodsFive online databases (PsycINFO, PubMed, SPORTDiscus, Web of Science, and Ovid MEDLINE) were searched for relevant peer-reviewed studies published between January 2015 and January 2020 that met the a priori inclusion criteria, with no study design limits. The methodological quality of research evidence for each individual study and for each health indicator was assessed by using a modified version of the Downs and Black checklist.ResultsA total of 51 studies from 20 different countries met the inclusion criteria. A total of 31 studies examined adherence (meeting vs. not meeting) to 24-h movement guidelines, and 20 studies used compositional analyses to explore the 24-h time-use composition of movement behaviors. Findings indicated that meeting the 24-h movement guidelines were (1) not associated with adiposity among toddlers, (2) favorably associated with health-related quality of life, social-cognitive development, and behavioral and emotional problems among preschoolers, (3) favorably associated with global cognition, health-related quality of life, and healthy dietary patterns in children, and (4) favorably associated with adiposity, fitness, and cardiometabolic, mental, social, and emotional health among children and youth. Significant associations were also found between the composition of 24-h movement behaviors and indicators of (1) adiposity and bone and skeletal health among preschoolers, (2) health-related quality of life among children, (3) adiposity, fitness, and cardiometabolic, social, and emotional health among children and youth, (4) cardiometabolic health in adults, (5) adiposity and fitness among adults and older adults, and (6) mental health and risk of mortality among older adults. The quality of the available evidence ranged from poor to good.ConclusionThe current evidence indicates that the composition of movement behaviors within a 24-h period may have important implications for health at all ages and that meeting the current 24-h movement guidelines is associated with a number of desirable health indicators in children and youth. Future studies should employ longitudinal and experimental designs, include valid and reliable measures of 24-h movement behaviors, and examine a wide array of health indicators across all age groups. Such studies would confirm the results from the primarily cross-sectional evidence drawn from studies included in our review and further advance our understanding of the relationships between 24-h movement behaviors and health. 相似文献

The pulse oximeter is a device that measures the oxygen concentration (or oxygen saturation—SpO2); heart rate, and heartbeat of a person at any given time. This instrument is commonly used in medical and aerospace fields to monitor physiological outputs of a patient according to health conditions or physiological yields of a flying pilot according to changes in altitude and oxygen availability in the atmosphere. Nonetheless, the uses for pulse oximetry may expand to other fields where there is human interaction and where physiological outputs reflect fluctuations mediated by arising emotions. A classroom, for instance is filled with a plethora of emotions, but very often participants in this space are unaware of others’ or their own sentiments as these arise as a result of interactions and responses to class discussions. In this paper I describe part of a larger study-taking place at Brooklyn College of the City University of New York. The focus is on the exploration of emotions and mindfulness in the science classroom. The oximeter is used in this study as a reflexive tool to detect emotions emerging among participants of a graduate History and Philosophy of Science Education course offered in the spring of 2012. Important physiological information of class participants provided by the oximeter is used to analyze the role of emotions in the classroom as sensitive and controversial topics in science education are discussed every week. 相似文献

This study examined emotion regulation (ER) as a mediator in the relation between early behavioral inhibition (BI) and later social competence (N = 257), and whether this mediation varied depending on BI levels. Maternal report and observational measures were used to assess BI (ages 2 and 3). Children's ER strategies (age 5) and social competence with an unfamiliar peer (age 7) were measured using observational measures. Results showed that BI predicted less engaged ER strategies during a disappointment task, and engaged ER predicted higher social competence. Engaged ER mediated the effect of BI on social competence, but only for highly inhibited children. Findings elucidate developmental trajectories of risk and resilience, and suggest targeting regulatory strategies in early prevention efforts with highly inhibited children. 相似文献

Introduction:
We examined the cost-effectiveness of the three different D-dimer measurements in the screening of DVT in models with and without calculation of pre-test probability (PTP) score. Moreover, we calculated the minimal cost in DVT detection.Material and methods:
In the group of 192 patients with clinically suspected acute DVT, we examined the three different D-dimer measurements (Innovance D-dimer, Hemosil D-dimer HS and Vidas D-dimer Exclusion II) in combination with and without PTP assessment.Results:
The diagnostic alternative employing Vidas D-dimer Exclusion II assay without and with PTP calculation gave lower incremental cost-effectiveness ratio (ICER) than the alternative employing Hemosil D-dimer HS assay (0.187 Euros vs. 0.998 Euros per one additional DVT positive patient selected for CUS in model without PTP assessment and 0.450 vs. 0.753 Euros per one DVT positive patient selected for CUS in model with PTP assessment). According to sensitivity analysis, the Hemosil D-dimer HS assay was the most cost effective alternative when one patient was admitted to the vascular ambulance per day. Vidas D-dimer Exclusion II assay was the most cost effective alternative when more than one patient were admitted to the vascular ambulance per day. Cost minimisation analysis indicated that selection of patients according to PTP score followed by D-dimer analysis decreases the cost of DVT diagnosis.Conclusions:
ICER analysis enables laboratories to choose optimal laboratory tests according to number of patients admitted to laboratory. Results support the feasibility of using PTP scoring and D-dimer measurement before CUS examination in DVT screening. 相似文献157.

INTRODUCTION The Yang-Baxter equation(Yang,1967;Baxter,1972)is one of the most valuable concepts in modern theoretical physics(Baxter,1982).The importance of detailed study of Yang-Baxter equation solutions is due to its key role in constant solution models of sta-tistics mechanics(Baxter,1972;1982)and field the-ory in lower dimensions(Yang,1967),conformal field theory(Di Francesco et al.,1997)and in quan-tum integrable systems(Faddeev et al.,1990).From the group-theoretical viewpoint… 相似文献

General pedagogical knowledge (GK) as part of teachers’ professional knowledge has been receiving increasing attention in empirical research. Current results are based on the assumption that GK is conceptualized and acquired during teacher education independent from the subjects being studied. Therefore, we examine whether GK can be measured comparably across subjects and whether differences exist among teachers from different subject specializations concerning their level of GK. Results from 2616 preservice teachers starting their induction phase indicate that knowledge can be invariantly measured across three subject groups, i.?e., science, languages/humanities and a combination of these subjects. However, teachers vary systematically depending on their subject specializations (controlling for gender, language, grade point average, and school track). Science teachers achieve higher test scores for diagnostic/evaluation and lower scores in fields more removed from direct instruction (e.?g., theory of education). There are no differences concerning knowledge directly related to instruction (e.?g., learning/development). Results are discussed with reference to subject-related factors of socialisation, selection and development in the profession. 相似文献

Special educational needs and disability 总被引:1,自引:0,他引:1
Issues relating to the categorisation and labelling of pupils, and, the use of the terms 'special educational needs' and 'disability' in particular, have been the topic of debate in BJSE before. In this article, Sue Keil, a research officer at the Royal National Institute for the Blind (RNIB), Olga Miller, of the Institute of Education, University of London, and Rory Cobb, a development officer at the RNIB, summarise some of the key findings from a review carried out on behalf of the Disability Rights Commission (DRC). The authors highlight confusion over the use of terms that represent differing ideological perspectives. Despite the social focus that characterises much of the discourse about disability, disability is frequently regarded as an aspect of special educational needs, an area in which a medical model is often dominant. These confusions benefit neither children with disabilities nor those with less clearly-defined difficulties. Sue Keil, Olga Miller and Rory Cobb note with interest recent developments in Scotland where a new framework based on the concept of 'additional support needs' separates disability from educational need and is intended to represent a more inclusive approach to children's learning. 相似文献
