The circulation of expertise in teachers’ professional communities     

Shelly Wilburn 《International Studies in Sociology of Education》2019,28(2):146-167

This study qualitatively explores expertise as a critical resource on which quality teaching depends. The study sample is comprised of six South African schools from the poorest poverty quintiles achieving relatively higher and lower academic outcomes. From interview data gathered over three years with teachers and other school staff, findings reveal significant differences between schools in the kinds of expertise that circulate in teacher communities. Remediation strategies that support student learning at specific levels of complexity stand out as a significant form of expertise. In schools performing above demographic expectations, teachers have more opportunities to access knowledge as an instructional resource, enabled by the recognition of differences in expertise. The study offers insight into what kinds of pedagogic strategies might disrupt educational inequalities and support the quality of teaching and learning within a system of scarce resources.  相似文献   

Topping the Classroom Charts: Teaching Criminological Theory Using Popular Music     

Reneè D. Lamphere  Nakita M. Shumpert  Shelly L. Clevenger 《Journal of Criminal Justice Education》2015,26(4):530-544

Today’s students are entering college having been immersed in media to an extent that has not been seen previously. The media-driven influence on college students has led many educators to use non-traditional mediums to engage their classes in meaningful learning experiences. Many educators advocate for the use of music and/or musical lyrics as a non-traditional teaching tool, specifically to illustrate the basic concepts of criminological theory. While many types of songs and lyrics could be used to teach criminological theory to undergraduate college students, the emphasis of this particular paper is on the use of popular music. Included is a discussion of using non-traditional instruction in the college classroom, student examples of theory application to popular music, and suggestions for implementing popular music in the classroom.  相似文献

Flow of DNA solutions in a microfluidic gradual contraction     

Shelly Gulati  Susan J. Muller  Dorian Liepmann 《Biomicrofluidics》2015,9(5)

The flow of λ-DNA solutions in a gradual micro-contraction was investigated using direct measurement techniques. The effects on DNA transport in microscale flows are significant because the flow behavior is influenced by macromolecular conformations, both viscous and elastic forces dominate inertial forces at this length scale, and the fully extended length of the molecule approaches the characteristic channel length w_c (L/w_c ∼ 0.13). This study examines the flow of semi-dilute and entangled DNA solutions in a gradual planar micro-contraction for low Reynolds numbers (3.7 × 10⁻⁶< Re < 3.1 × 10⁻¹) and high Weissenberg numbers (0.4 < Wi < 446). The semi-dilute DNA solutions have modest elasticity number, El = Wi/Re = 55, and do not exhibit viscoelastic behavior. For the entangled DNA solutions, we access high elasticity numbers (7.9 × 10³< El < 6.0 × 10⁵). Video microscopy and streak images of entangled DNA solution flow reveal highly elastic behavior evidenced by the presence of large, stable vortices symmetric about the centerline and upstream of the channel entrance. Micro-particle image velocimetry measurements are used to obtain high resolution, quantitative velocity measurements of the vortex growth in this micro-contraction flow. These direct measurements provide a deeper understanding of the underlying physics of macromolecular transport in microfluidic flow, which will enable the realization of enhanced designs of lab-on-a-chip systems.  相似文献   

Dissymmetry and asymmetry     

Chandan Saha  Suchandra Chakraborty 《Resonance》2012,17(8):768-778

In French science literature, the term dissymmetry appeared as early as in 1820, before Louis Pasteur. Pasteur, a French scientist, in his lecture ??Recherches sur la Dissymétrie Moléculaire des Produits Organiques Naturels?? in 1860 used the term dissymmetric which was translated in English as asymmetric. A methodical study of his work reveals that the choice of the word dissymmetry is ideal even in the context of present-day science. Strictly speaking, there should be no conflict between the two terms dissymmetry and asymmetry.  相似文献   

Assessment of Insulin Resistance and Metabolic Syndrome in Drug Naive Patients of Bipolar Disorder

The levels of fasting glucose, fasting insulin, insulin resistance (IR) and the prevalence of metabolic syndrome (MS) in a sample population of bipolar disorder (BPD) patients who were newly diagnosed and psychotropically naïve were assessed and compared with an age, sex and racially matched control population. 55 BPD-I patients (15–65 years) who were non-diabetic, nonpregnant, and drug naïve for a period of at least 6 months were included in the study. Diagnosis was made using the structured clinical interview for DSM-IV axis I disorders (SCID IV). IR was assessed using homeostasis model of insulin resistance (HOMA-IR); MS was defined according to National Cholesterol Education Program-Adult Treatment Panel III (NCEP-ATP III). Data were compared with 25 healthy controls. BPD patients had significantly higher mean levels of fasting plasma insulin (13.2 ± 9.2 vs. 4.68 ± 3.1 μIU/ml, p < 0.05), postprandial plasma insulin (27.2 ± 14.5 vs. 18.1 ± 9.3 μIU/ml, p < 0.05) and a higher value of HOMA-IR (3.16 ± 2.2 vs. 1.19 ± 0.8, p < 0.05) when compared to the controls. A significantly higher proportion of patients of BPD compared to controls were manifesting levels of fasting plasma glucose, serum triglyceride and blood pressure higher than the cut off while waist circumference and serum HDL cholesterol failed to show any significant difference in the proportion. There was a significantly higher proportion of prevalence of IR between BPD cases and controls (26/55 vs. 2/25, z value 9.97, p < 0.05) while there was no significant difference in proportion of prevalence of MS between these two groups. Within BPD patients, logistic regression analysis showed that age, sex or current mood status (depressed/manic) were not significantly predictive of presence or absence of MS or increased IR.  相似文献   

The persuasive effects of statistical evidence in the presence of exemplars     

Franklin J. Boster  Kenzie A. Cameron  Shelly Campo  Wen‐Ying Liu  Janet K. Lillie  Esther M. Baker 《Communication Studies》2013,64(3):296-306

This paper explores the impact of statistical evidence by varying it while pairing it with a constant set of exemplars. The resulting design includes a condition in which the statistical information and the exemplars advocate the same position (consistent condition), one in which statistical information and the exemplars advocate different positions (inconsistent condition), and a third condition in which only exemplars are presented (control condition). The data indicate that statistical evidence has a substantial effect on judgments, and that the impact of statistical evidence on attitudes is indirect. Specifically, it is mediated by judgments.  相似文献   

Weight Bias and Social Justice: Implications for Education and Practice     

Sarah Nutter  Shelly Russell-Mayhew  Nancy Arthur  John H. Ellard 《International journal for the advancement of counseling》2018,40(3):213-226

Weight bias is a widespread and persistent form of oppression that adversely impacts the lives of individuals with obesity in many areas of society. In this paper, we discuss the implications of weight bias as a social justice issue for counsellor education and practice. We provide recommendations for professional education, including the need to examine social location, knowledge, assumptions, and biases about weight and individuals with obesity. We also provide recommendations related to advocacy for individuals with obesity in practice.  相似文献   

The secretary problem     

Arnab Chakraborty M.Stat st Year Student 《Resonance》1996,1(9):41-50

In many spheres of activity, decisions must often be made under uncertain conditions. One such problem relates to selecting a candidate from a known number when: (a) candidates arrive in a sequence; (b) the selection process has to decide on a candidate then and there; (c) the process terminates if a candidate is selected; (d) the process continues if the candidate is not selected. The question is: What is the strategy that maximises the probability of selecting the best candidate? How does one use the ‘scores’ of each of the candidates seen so far to decide if the present candidate must be selected or if the process be continued, in the quest for the best candidate? This is the problem ofoptimal stopping, an example of which is discussed here.  相似文献
