Brief encounter: the use of consultancy projects to enhance the learning experience of postgraduate marketing students

There has been a growing recognition of the need for management education to embed the ‘practice’ of management in curricula, and more effectively manage the relationships between organisations and business schools. The recent report of a Government-initiated Task Force to address such concerns highlighted designing practice into courses as a key area for change (Thorpe and Rawlinson, 2013). Many business schools have introduced consultancy projects into marketing courses as a way of bringing this practical experience into the curriculum and in some cases are being ‘scaled up’ to replace dissertations or other major projects. At Master’s level across Europe, The Rotterdam School of Management (2013) find that 29% of final projects take the form of a field project, normally via an internship or consultancy project. The aim of this paper is to evaluate one such consultancy project for a MSc Marketing course at a Midlands Business School. Whilst existing studies highlight gaps between graduate skills and knowledge and those sought by employers, or between what students expect and what they receive in respect of practical experience, few studies specifically focus on the operation of consultancy projects nor do they seek to investigate the associated tensions between constituent groups. This project therefore seeks to do this and to make recommendations to other marketing educators considering the use of or currently using consultancy projects

Gesture as an act of meaning-making: An eco-social perspective of a sheltered-English second grade classroom

The purpose of this sociocultural study was to investigate gesture as a mediational tool for meaning-making in learning and teaching a second language. Gesture was observed between a teacher and her immigrant students in a second grade elementary classroom designed specifically for second language learners of English. This study provides an innovative investigation in the role gesture plays as a meditational tool for meaning-making by using a SCT framework at an elementary context level. Using sociocultural theory, particularly the Vygotskian tradition, this study views gesture as a part of image in thinking. This SCT framework views second language learning in a holistic way, where language is not disembodied from making sense and is not divided in its image and speech components. The study considers gesture as an indivisible part of language, thinking, and meaning-making. In addition, gesture is viewed for its affordances for making meaning as created by both first and second language English speakers. Through the use of dialectics and dialogism, this study views gesture and speech in-vivo and as synthesized parts of language and necessary components to meaning-making for second language learning

Modeling radiation forces acting on TOPEX/Poseidon for precision orbit determination

Geodetic satellites such as GEOSAT, SPOT, ERS-1, and TOPEX/Poseidon require accurate orbital computations to support the scientific data they collect. Until recently, gravity field mismodeling was the major source of error in precise orbit definition. However, albedo and infrared re-radiation, and spacecraft thermal imbalances produce in combination no more than a 6-cm radial root-mean-square (RMS) error over a 10-day period. This requires the development of nonconservative force models that take the satellite's complex geometry, attitude, and surface properties into account. For TOPEX/Poseidon, a 'box-wing' satellite form was investigated that models the satellite as a combination of flat plates arranged in a box shape with a connected solar array. The nonconservative forces acting on each of the eight surfaces are computed independently, yielding vector accelerations which are summed to compute the total aggregate effect on the satellite center-of-mass. In order to test the validity of this concept, 'micro-models' based on finite element analysis of TOPEX/Poseidon were used to generate acceleration histories in a wide variety of orbit orientations. These profiles are then compared to the box-wing model. The results of these simulations and their implication on the ability to precisely model the TOPEX/Poseidon orbit are discussed

Risk and charitable organizations: the case of Atlantic Canada

Using panel data from 2003-2010 on charitable organizations in Canada we explore the implications that exposure to risk, in various guises, has on organizations' ability to meet their mandate. We run a random effects panel estimation focusing our attention on the case of Atlantic Canada in an effort to explore the idiosyncrasies that make it an interesting case study, and a microcosm of sorts for producing risk metrics in general. A comparative analysis is provided with the Canadian charitable sector as a whole to contrast the results and afford a context for discussion. Results suggest that diversification in revenue streams may in fact increase risk for charitable firms; and comprehensive modeling techniques, which categorize the entire Canadian market quite well, lead to increased noise in estimating exposure to risk for Atlantic Canada firms. The latter seem somewhat more sensitive to exogenous economic changes, when compared to the entire marketplace

Velocity-Resolved Reverberation Mapping of NGC 3227

We describe the results of a new reverberation mapping program focused on the nearby Seyfert galaxy NGC 3227. Photometric and spectroscopic monitoring were carried out from 2022 December to 2023 June with the Las Cumbres Observatory network of telescopes. We detected time delays in several optical broad emission lines, with H$\beta$ having the longest delay at $\tau_{\rm cent}=4.0^{+0.9}_{-0.9}$ days and He II having the shortest delay with $\tau_{\rm cent}=0.9^{+1.1}_{-0.8}$ days. We also detect velocity-resolved behavior of the H$\beta$ emission line, with different line-of-sight velocities corresponding to different observed time delays. Combining the integrated H$\beta$ time delay with the width of the variable component of the emission line and a standard scale factor suggests a black hole mass of $M_{\rm BH}=1.1^{+0.2}_{-0.3} \times 10^7 M_{\odot}$. Modeling of the full velocity-resolved response of the H$\beta$ emission line with the phenomenological code CARAMEL finds a similar mass of $M_{\rm BH}=1.2^{+1.5}_{-0.7} \times 10^7 M_{\odot}$, and suggests that the H$\beta$-emitting broad line region (BLR) may be represented by a biconical or flared disk structure that we are viewing at an inclination angle of $\theta_i \approx 33^{\circ}$ and with gas motions that are dominated by rotation. The new photoionization-based BLR modeling tool BELMAC finds general agreement with the observations when assuming the best-fit CARAMEL results, however BELMAC prefers a thick disk geometry and kinematics that are equally comprised of rotation and inflow. Both codes infer a radially extended and flattened BLR that is not outflowing.Comment: 16 pages, 9 figures, 4 tables; submitted to Ap

The Pioneer Anomaly

Radio-metric Doppler tracking data received from the Pioneer 10 and 11 spacecraft from heliocentric distances of 20-70 AU has consistently indicated the presence of a small, anomalous, blue-shifted frequency drift uniformly changing with a rate of ~6 x 10^{-9} Hz/s. Ultimately, the drift was interpreted as a constant sunward deceleration of each particular spacecraft at the level of a_P = (8.74 +/- 1.33) x 10^{-10} m/s^2. This apparent violation of the Newton's gravitational inverse-square law has become known as the Pioneer anomaly; the nature of this anomaly remains unexplained. In this review, we summarize the current knowledge of the physical properties of the anomaly and the conditions that led to its detection and characterization. We review various mechanisms proposed to explain the anomaly and discuss the current state of efforts to determine its nature. A comprehensive new investigation of the anomalous behavior of the two Pioneers has begun recently. The new efforts rely on the much-extended set of radio-metric Doppler data for both spacecraft in conjunction with the newly available complete record of their telemetry files and a large archive of original project documentation. As the new study is yet to report its findings, this review provides the necessary background for the new results to appear in the near future. In particular, we provide a significant amount of information on the design, operations and behavior of the two Pioneers during their entire missions, including descriptions of various data formats and techniques used for their navigation and radio-science data analysis. As most of this information was recovered relatively recently, it was not used in the previous studies of the Pioneer anomaly, but it is critical for the new investigation.Comment: 165 pages, 40 figures, 16 tables; accepted for publication in Living Reviews in Relativit

The XMM Cluster Survey: New evidence for the 3.5-keV feature in clusters is inconsistent with a dark matter origin

There have been several reports of a detection of an unexplained excess of X-ray emission at $\simeq$3.5 keV in astrophysical systems. One interpretation of this excess is the decay of sterile neutrino dark matter. The most influential study to date analysed 73 clusters observed by the XMM-Newton satellite. We explore evidence for a â 3.5-keV excess in the XMM-PN spectra of 117 redMaPPer galaxy clusters (0.1 < z < 0.6). In our analysis of individual spectra, we identify three systems with an excess of flux at $\simeq$3.5 keV. In one case (XCS J0003.3+0204), this excess may result from a discrete emission line. None of these systems are the most dark matter dominated in our sample. We group the remaining 114 clusters into four temperature (TX) bins to search for an increase in â 3.5-keV flux excess with TX-a reliable tracer of halo mass. However, we do not find evidence of a significant excess in flux at â 3.5 keV in any TX bins. To maximize sensitivity to a potentially weak dark matter decay feature at â 3.5 keV, we jointly fit 114 clusters. Again, no significant excess is found at â 3.5 keV. We estimate the upper limit of an undetected emission line at â 3.5 keV to be 2.41 × 10-6 photons cm-2 s-1, corresponding to a mixing angle of sin 2(2θ) = 4.4 × 10-11, lower than previous estimates from cluster studies. We conclude that a flux excess at â 3.5 keV is not a ubiquitous feature in clusters and therefore unlikely to originate from sterile neutrino dark matter decay. © 2020 The Author(s) Published by Oxford University Press on behalf of the Royal Astronomical Society
