Uncovering The Legacy of Policy An Ethnographic Account of a Secondary School’s Commitment to Creativity

Uncovering The Legacy of Policy. An Ethnographic Account of a Secondary School’s Commitment to Creativity By Pauline Moger In the field of policy to date there is a tendency to focus upon the complexities of process associated with policy enactment; investigating the relationship between national policy discourse and the ways in which this discourse is creatively reconstituted in school-based contexts of practice. This thesis is concerned with the ways in which a school-based commitment to a specific policy – in this instance creativity – is sustained and has a legacy even after national policy discourse and priorities have changed. The thesis employs an overarching ethnographic method and qualitative inquiry of the ‘field’ through which the research questions and aims are explored. The research approach adopted is a case study. The nature of relations and relationships in consideration and enactment of policy as legacy is examined and presented. A symbolic interactionist framework is employed to understand and interpret the interactional processes involved in the policy legacy of creativity. The study identifies key factors and elements that play a critical part in a continued commitment to creativity in education, enacted through policy as a continuum of practice, building upon the seminal work of scholars such as Ball, Braun and McGuire. In this process this study locates and understands the context and significance of interaction between key policy actors pivotal to sustaining and embedding a commitment to creativity and as such questions established policy enactment conceptualization

Classification of Arbitrary Motion into a Canonical Basis

The Empatica E4 wristwatch utilizes four sensors to capture medical data from its user - an accelerometer, a plethysmograph, an electro-dermal activity sensor, and an infrared thermophile. Utilizing these sensors, the device can provide detection-based feedback for patients suffering from various ailments. However, each sensor is coupled with the other readings, so any raw data will have a degree of noise accompanying the actual signal. After detailing a conceptual and programming knowledge of various industry-standard data processing techniques, we follow the appropriate steps to take in order to clean up a noisy E4 data signal, starting with supervised basis signals and ending with unsupervised, random samples. We conclude with a discussion of how one can decompose arbitrary motions into a canonical basis for proper data analysis, providing insight based on our results

AYURVEDIC MANAGEMENT OF HANUSTAMBHA: A CASE STUDY

Life without movement is impossible to think of in a healthy person’s normal life. Hanugraha or Hanustambha is one of the commonest problem affects irrespective of sex, age and socioeconomic status etc. The disease has the symptoms like stiffness of jaw with or absence of pain. The symptoms are seen suddenly with chronic Nidana Sevana. Jaw dislocation occurs when the lower part of the jaw moves out of its normal position. Temporomandibular joint disorder can cause pain, abnormal joint movements and joint noises. The life time incidence of Temporomandibular joint disorder is more than 10 million cases per year in India. In Hanugraha, Vata is predominantly involved. Here an attempt is made on Hanustambha with Ayurvedic management

Hot phonon decay in supported and suspended exfoliated graphene

Near infrared pump-probe spectroscopy has been used to measure the ultrafast dynamics of photoexcited charge carriers in monolayer and multilayer graphene. We observe two decay processes occurring on 100 fs and 2 ps timescales. The first is attributed to the rapid electron-phonon thermalisation in the system. The second timescale is found to be due to the slow decay of hot phonons. Using a simple theoretical model we calculate the hot phonon decay rate and show that it is significantly faster in monolayer flakes than in multilayer ones. In contrast to recent claims, we show that this enhanced decay rate is not due to the coupling to substrate phonons, since we have also seen the same effect in suspended flakes. Possible intrinsic decay mechanisms that could cause such an effect are discussed.Comment: 4 pages, 3 figure

File “07 AFM data.txt” is AFM data for a modified area of a monolayer graphene sample.The modification of single layer graphene due to intense, picoseconds near-infrared laser pulses is investigated. We monitor the stable changes introduced to graphene upon photoexcitation using Raman spectroscopy. We find that photoexcitation leads to both a local increase in hole doping and a reduction in compressive strain. Possible explanations for these effects, due to photo-induced oxygenation and photo-induced buckling of the graphene, are discussed.CEMPS Research Project Studentshi

Imaging the uptake of gold nanoshells in live cells using plasmon resonance enhanced four wave mixing microscopy

This paper was published in Optics Express and is made available as an electronic reprint with the permission of OSA.

Systematic or multiple reproduction or distribution to multiple locations via electronic or other means is prohibited and is subject to penalties under law.Gold nanoshells (GNS) are novel metal nanoparticles exhibiting attractive optical properties which make them highly suitable for biophotonics applications. We present a novel investigation using plasmon-enhanced four wave mixing microscopy combined with coherent anti-Stokes Raman scattering (CARS) microscopy to visualize the distribution of 75 nm radius GNS within live cells. During a laser tolerance study we found that cells containing nanoshells could be exposed to < 2.5 mJ each with no photo-thermally induced necrosis detected, while cell death was linearly proportional to the power over this threshold. The majority of the GNS signal detected was from plasmon-enhanced four wave mixing (FWM) that we detected in the epi-direction with the incident lasers tuned to the silent region of the Raman spectrum. The cellular GNS distribution was visualized by combining the epi-detected signal with forwards-detected CARS at the CH2 resonance. The applicability of this technique to real-world nanoparticle dosing problems was demonstrated in a study of the effect of H2S on nanoshell uptake using two donor molecules, NaHS and GYY4137. As GYY4137 concentration was increased from 10 µM to 1 mM, the nanoshell pixel percentage as a function of cell volume (PPCV) increased from 2.15% to 3.77%. As NaHS concentration was increased over the same range, the nanoshell PPCV decreased from 12.67% to 11.47%. The most important factor affecting uptake in this study was found to be the rate of H2S release, with rapid-release from NaHS resulting in significantly greater uptake

Case-cohort Methods for Survival Data on Families from Routine Registers

In the Nordic countries, there exist several registers containing information on diseases and risk factors for millions of individuals. This information can be linked into families by use of personal identification numbers, and represent a great opportunity for studying diseases that show familial aggregation. Due to the size of the registers, it is difficult to analyze the data by using traditional methods for multivariate survival analysis, such as frailty or copula models. Since the size of the cohort is known, case-cohort methods based on pseudo-likelihoods are suitable for analyzing the data. We present methods for sampling control families both with and without replacement, and with or without stratification. The data are stratified according to family size and covariate values. Depending on the sampling method, results from simulations indicate that one only needs to sample 1%-5% of the control families in order to get good efficiency compared to a traditional cohort analysis. We also provide an application to survival data from the Medical Birth Registry of Norway

Strong nonlinear optical response of graphene flakes measured by four-wave mixing

We present the first experimental investigation of nonlinear optical properties of graphene flakes. We find that at near infrared frequencies a graphene monolayer exhibits a remarkably high third-order optical nonlinearity which is practically independent of the wavelengths of incident light. The nonlinear optical response can be utilized for imaging purposes, with image contrasts of graphene which are orders of magnitude higher than those obtained using linear microscopy.Comment: 4 pages, 5 figure
