The targum (1880:Apr.)
Creators: name: No Name Supplied
Publisher: name: Targum Association
Year: 1880

description: Some University historians indicate that the Targum was first published as an annual in 1867, but of this we have no extant evidence. In January 1869, the Targum as we now know it, made its appearance as a monthly paper that concerned itself with student “literary contributions” and college news as well as serving as a vehicle for bringing news to alumni and the general public. The newspaper, which originally was for sale, varied in frequency over the years as did its title (The Targum, Rutgers Targum, Rutgers Daily Targum, and Daily Targum). The newspaper has continuously been published since 1869 with the exception of 19 months during the second world war, between February 1944 and October 1945. The Targum was published by the students of Rutgers College, and later Rutgers University—New Brunswick represented through the years as the Targum Association, Rutgers Targum Association, and Rutgers College Targum. As a student organization, the Targum operated under the oversight of the dean of students and student government but in October 1980, the Targum became an independent college paper.

description: Coupled resonator optical waveguides (CROW) can significantly reduce light propagation pulse velocity due to pronounced dispersion properties. A number of interesting applications have been proposed to benefit from such slow-light propagation. Unfortunately, the inevitable presence of disorder, imperfections, and a finite Q value may heavily affect the otherwise attractive properties of CROWs. We show how finite a Q factor limits the maximum attainable group delay time; the group index is limited by Q, but equally important the feasible device length is itself also limited by damping resulting from a finite Q. Adding the additional effects of disorder to this picture, limitations become even more severe due to destructive interference phenomena, eventually in the form of Anderson localization. Simple analytical considerations demonstrate that the maximum attainable delay time in CROWs is limited by the intrinsic photon lifetime of a single resonator.

description: Evolutionary dynamics in finite populations is known to fixate eventually in the absence of mutation. We here show that a similar phenomenon can be found in stochastic game dynamical batch learning, and investigate fixation in learning processes in a simple 2x2 game, for two-player games with cyclic interaction, and in the context of the best-shot network game. The analogues of finite populations in evolution are here finite batches of observations between strategy updates. We study when and how such fixation can occur, and present results on the average time-to-fixation from numerical simulations. Simple cases are also amenable to analytical approaches and we provide estimates of the behaviour of so-called escape times as a function of the batch size. The differences and similarities with escape and fixation in evolutionary dynamics are discussed.

description: An electron-phonon cavity consisting of a quantum dot embedded in a freestanding GaAs/AlGaAs membrane is characterized using Coulomb blockade measurements at low temperatures. We find a complete suppression of single electron tunneling around zero bias leading to the formation of an energy gap in the transport spectrum. The observed effect is induced by the excitation of a localized phonon mode confined in the cavity. This phonon blockade of transport is lifted at discrete magnetic fields where higher electronic states with nonzero angular momentum are brought into resonance with the phonon energy.

description: Periodicity is one of the most fundamental structural characteristics of systems occurring in nature. The properties of these systems depend strongly on the symmetry of the underlying periodic structure. In solid state materials - for example - the static and transport properties as well as the magnetic and electronic characteristics are crucially influenced by the crystal symmetry. In this context, hexagonal structures play an extremely important role and lead to novel physics like that of carbon nanotubes or graphene. Here we report on the first realization of ultracold atoms in a spin-dependent optical lattice with hexagonal symmetry. We show how combined effects of the lattice and interactions between atoms lead to a forced antiferromagnetic Néel order when two spin-components localize at different lattice sites. We also demonstrate that the coexistence of two components - one Mott-insulating and the other one superfluid - leads to the formation of a forced supersolid. Our observations are consistent with theoretical predictions using Gutzwiller mean-field theory.

title: The “Inside” and “Outside” Perspectives of Corporate Rebranding: A case study of Greggs Plc
Creators: name: Kolawole, Bridget
Publisher: name: The University of East London
Year: 2018

description: 2018 dissertation for MSc. International Business Management. Selected by academic staff as a good example of a masters level dissertation. Corporate rebranding has become a popular topic for both researchers and practitioners in the few decades. When learning from some failed rebranding cases like Royal Mail, retaining and engaging both employees and consumers could be one of the keys to the success of corporate rebranding as stakeholders always show support to the brand. It is a new and seldom studied area in the academic field. To date, empirical research on the meaning of corporate rebranding to consumers and employees has received less attention. In filling this gap, this study attempted to examine the understanding of employees and consumers concerning corporate rebranding and the effect of it. More so, to know their level of involvement in the corporate rebranding process and implementation. The study was premised on the corporate rebranding process and principles and the involvement theory.
The study adopted positivism philosophy based on the theory of corporate rebranding process and principles. To evaluate the research, Greggs plc was selected since it has been undergoing a corporate rebranding in the past five years successfully by repositioning its brand into another market. Both qualitative and quantitative data were used to understand consumers and employees’ feelings of corporate rebranding. This includes the focus group discussion with seven employees, semi-structured interview with a Greggs manager and a questionnaire survey disseminated to Greggs customers.
The findings revealed that the consumers and employees had a mixed perception about the rebranding strategies concerning the level of involvement and their feelings about the brand. Another result is that the brand image that Greggs is trying to achieve is not clear and most of the consumers are only loyal in terms of consumption, not to the brand which might have been caused by low level of involvement and inadequate awareness of the rebranding strategy. Some recommendations for management and future researchers were also suggested.

title: What attributes from Food Aesthetics, Service Quality Cues or the Roles, Consumption Rituals or The Norms and Boundaries of the Service Provider contributes to customer Service Experience in a Fine Dining restaurant context?
Creators: name: Wilson, Shantal
Publisher: name: The University of East London
Year: 2018

description: 2018 dissertation for MSc. International Business Management. Selected by academic staff as a good example of a masters level dissertation. This is a qualitative paper where the focus is to investigate consumer service experience in fine dining restaurant context. To identify the relevant attributes that contribute to consumer service experience, seven participants who have eaten at fine dining restaurants previously where interviewed. The semi-structured interview had pre-prepared questions, cover the following them, Food Consumption and Fine Dining, Experience Marketing and Service Experience. Each theme covered questions, focused on the consumer perspective on fine dining restaurants, as well as what contribute to the service experience in fine dining restaurants. 

From the research the following themes emerged as significant to the customer service experience: Conspicuous Consumption, Food Aesthetics, Service Quality Cues, Consumption Rituals and the Roles, Norms and Boundaries of the Service Provider. The main findings of the research implied that consumers enjoy the experience that fine dining restaurants has to offer. however, the food aesthetics are not always to customers standards are expectations in comparison to what the customer must pay. 

To conclude, the main arguments that emerged was that, fine dining restaurant experience is more about people showing off, a display of status and self-validation of one’s worth. The role that the food play isn’t has significant to customers. However, what does matter to customers as significant to their service experience, are the service quality cues. The smaller intangible gestures, the role of the service provider is just as important. As there is a fine line, with the attention provided by the employee staff this can be over bearing to customers. 

In terms of recommendations, for future the studies the ritualistic approach to fine dining emerged as a way in which customers can enjoy fine dining experience. In the form of a treat or for special occasions. This can be adopted with a quantitative methodology approach. For restauranteurs, the findings suggest that customers require some boundaries. Therefore, to implement this, the manager can start by adding this information in their training programmes to the staff, and the incorporate it in their everyday business practice.

description: The application of quantum field theoretical methods to strongly interacting many-body problems has reaped rich rewards. Foremost, it has nurtured the quasi-particle notion. The introduction of suitable fictitious entities permits to cast otherwise notoriously difficult many-body systems in a single-particle form. We can then take the customary physical approach, using concepts and representations which formerly could only be applied to systems with weak interactions, and still capture the essential physics. A most notable recent example occurs in the conduction properties of a two-dimensional electron system, when exposed to a strong perpendicular magnetic field B. They are governed by electron–electron interactions, that bring about the Nobel prize winning fractional quantum Hall effect (FQHE) (Perspectives on Quantum Hall effects, Wiley, New York, 1996). Composite fermions (CFs), that do not experience the external magnetic field but a drastically reduced effective magnetic field B*, were identified as opposite quasi-particles that simplify enormously the understanding of the FQHE (Phys. Today (2000) 39; Phys. Rev. Lett. 63 (1989) 199). They behave as legitimate particles with well-defined charge, spin and statistics (Phys. Rev. B 47 (1993) 7312; Composite Fermions, World Scientific, Singapore, 1998; Phys. Rev. Lett. 70 (1993) 2944; 75 (1995) 3926; 71 (1993) 3846; 72 (1994) 2065; 77 (1996) 2272). They precess, like electrons, along circular orbits, with a diameter determined by B* rather than B, and with a frequency that is hard to predict, since the effective mass remains enigmatic. Ever since their prediction, the demonstration of enhanced absorption of a microwave field that resonates with the frequency of their circular motion was considered the ultimate experiment to unravel this issue. Here, we report the observation of this cyclotron resonance of CFs with two and four flux quanta and extract their effective mass.

There are symmetric and asymmetric solutions, and some of them have simultaneously two different topological charges. Their regions of existence and stability are determined. Additionally, we have analyzed the relation- ship between dissipation and stability for a number of solutions. We have obtained that dissipation favours the stability of the solutions.

We can then take the customary physical approach, using concepts and representations which formerly could only be applied to systems with weak interactions, and yet still capture the essential physics. A most notable recent example occurs in the conduction properties of a two-dimensional electron system (2DES), when exposed to a strong perpendicular magnetic field B. They are governed by electron–electron interactions, that bring about the fractional quantum hall effect (FQHE). S. Das Sarma and A. Pinczuk (eds.), Perspectives on Quantum Hall Effects (Wiley, New York, 1996).

J. K. Jain, Phys. Today, 39–45 (2000). J. K. Jain, Phys. Rev. Lett. 63, 199–202 (1989). They precess, like electrons, along circular cyclotron orbits, with a diameter determined by B* rather than B.

Lett. 77, 2272–2275 (1996). The frequency of their cyclotron motion remained hitherto enigmatic, since the effective mass is no longer related to the band mass of the original electrons and is entirely generated from electron–electron interactions. Here, we demonstrate the enhanced absorption of a microwave field that resonates with the frequency of their circular motion. From this cyclotron resonance, we derive a composite fermion effective mass that varies from 0.7 to 1.2 times the electron mass in vacuum as their density is tuned from 0.6× 1011/cm2 to 1.2× 1011/cm2.
title: Investigation into key drivers of customer loyalty of independent coffee shops in the London coffee shop market
Creators: name: Petkovic, Ana
Publisher: name: The University of East London
Year: 2018

description: 2018 dissertation for MSc. International Business Management. Selected by academic staff as a good example of a masters level dissertation. In today’s highly saturated and competitive markets, customer loyalty emerges as one of the most important challenges faced by marketers. London’s independent coffee shop market can be identified as one of such complex business environments, where customers are often variety seeking and multi-brand loyal, which raises the question of how independent coffee shops can survive in such a competitive marketplace. This study aims to answer this question through the investigation of key drivers of customer loyalty of independent coffee shops in London’s coffee shop market. This study aims to examine the different groups of loyal customers in the coffee shop market, by examining the drivers and consequences of their loyal behaviours and attitudes, and by establishing the effect of relationship marketing strategies, such as loyalty programmes, on customer loyalty.

This study follows the positivist research philosophy and uses the quantitative research methodology for data collection. Data was collected using a self-administered questionnaire and analysed using a combination of quantitative data analysis strategies, including bivariate correlation analysis and multivariate analysis of variance. The research findings showed three distinctive groups of loyal customers in the independent coffee shop market, where levels of attitudes and behaviours displayed differ significantly between the groups. The study also identified that both functional and emotional drivers impact independent coffee shop customers’ loyalty, which then further significantly influences their post-purchase behaviour. The results of the study also showed that relationship marketing strategies have a weak effect on customers’ repeat-purchase loyalty. Based on these research findings, the study was then able to recommend the best practices in loyalty-building strategies for independent coffee shop managers.

description: We employ pulse shaping to abate single-qubit gate errors arising from the weak anharmonicity of transmon superconducting qubits. By applying shaped pulses to both quadratures of rotation, a phase error induced by the presence of higher levels is corrected. Using a derivative of the control on the quadrature channel, we are able to remove the effect of the anharmonic levels for multiple qubits coupled to a microwave resonator. Randomized benchmarking is used to quantify the average error per gate, achieving a minimum of 0.007+/-0.005 using 4 ns-wide pulse.

For tunable anisotropic structures that exhibit a vanishing dielectric response along a given axis, we find remarkable variation in the launch angles of energy associated with the emission of leaky wave radiation. We write closed form expressions for the energy transport velocity and corresponding radiation angle $ϕ$, defining the cone of radiation emission, both as a functions of frequency, and material and geometrical parameters. Full wave simulations exemplify the broad range of directivity that can be achieved in these structures.

Subjects: subject: High Energy Physics - Theory (hep-th)

description: This thesis consists of two parts. The first part deals with gauge/gravity duality in the context of anti de Sitter (AdS) spacetimes with de Sitter (dS) boundary, which can be used to study issues concerning strongly coupled field theory on de Sitter space, such as the issue of vacuum ambiguity. By calculating the symmetric two point function of the strongly coupled ${\cal N} = 4$ supersymmetric Yang-Mills theory on de Sitter space, we show that the vacuum ambiguity persists at strong coupling. Furthermore, the extra ambiguity in the strong coupling correlator seems to suggest that transition between two different vacua is allowed. The second part of this thesis deals with the duality between the rolling tachyon backgrounds in superstring theory and the Dyson gas systems. This duality can be interpreted as a reformulation of non-BPS D-branes in superstring theory in terms of statistical systems in thermal equilibrium, whose description does not include time. We argue that even though the concept of time is absent in the statistical dual sitting at equilibrium, the notion of time can emerge at the large number of particles $N \rightarrow \infty$ limit.

Reducing the tuberculosis burden in migrant populations through latent tuberculosis infection interventions : a series of cost-effectiveness analyses
Creators: name: Campbell, Jonathon
Publisher: name: University of British Columbia
Year: 2019

description: BACKGROUND: In many low tuberculosis (TB) incidence countries, TB rates have stagnated. In these countries, TB disproportionately affects migrant populations due to reactivation of latent TB infection (LTBI) acquired prior to immigration. Treatment of LTBI can significantly reduce risk of TB. The objective of this thesis is to determine the performance of common LTBI diagnostic tests in migrant populations and evaluate the cost-effectiveness of LTBI screening and treatment at various stages of the migration process and in migrants with chronic diseases, such as chronic kidney disease (CKD), that increase risk of TB. METHODS: A literature search determined the sensitivity of LTBI diagnostic tests: the tuberculin skin test (TST) and interferon-gamma release assay (IGRA). A meta-analysis was completed to determine the proportion of migrants testing positive with TST and IGRA from countries of various TB incidences. Discrete event simulation models evaluated the cost-effectiveness of LTBI screening and treatment in migrants: immediately post- immigration, prior to immigration, and at time of late stage CKD diagnosis or dialysis initiation. Incremental cost- effectiveness ratios (ICERs) were calculated for quality-adjusted life years. RESULTS: Sensitivities of 88.9% and 78.2% were found for the IGRA and TST, respectively. Fewer migrants test positive with an IGRA compared with a TST. Immediately after immigration, no LTBI screening was cost-effective when applied universally to all migrants (ICERs >$138,484), but can reduce the TB burden in migrants >20%. IGRA screening pre-immigration and rifampin treatment post-arrival can reduce the TB burden by >40% and results in ICERs <$49,035 compared to no screening in migrants from countries with a TB incidence ≥30 per 100,000. Likewise, in migrants from countries with a TB incidence ≥30 per 100,000, IGRA screening and isoniazid treatment at time of dialysis initiation was dominant and in migrants ≥60 years of age at late stage CKD diagnosis resulted in ICERs <$47,554. CONCLUSIONS: In order to sustainably reduce the migrant TB burden in low incidence countries, LTBI screening should be performed with an IGRA. LTBI screening should be targeted to migrants from countries with a TB incidence ≥30 per 100,000 pre-immigration or at high-risk of TB post-arrival, such as dialysis patients.

description: We have used the seven year Wilkinson Microwave Anisotropy Probe (WMAP) data in order to update the measurements of the intensity signal in the G159.6-18.5 region within the Perseus Molecular Complex, and to set constraints on the polarization level of the anomalous microwave emission in the frequency range where this emission is dominant. At 23, 33 and 41 GHz, we obtain upper limits on the fractional linear polarization of 1.0, 1.8 and 2.7% respectively (with a 95 per cent confidence level). These measurements rule out a significant number of models based on magnetic dipole emission of grains that consist of a simple domain (Draine & Lazarian 1999) as responsible of the anomalous emission. When combining our results with the measurement obtained with the COSMOSOMAS experiment at 11 GHz (Battistelli et al. 2006), we find consistency with the predictions of the electric dipole and resonance relaxation theory (Lazarian & Draine 2000) at this frequency range.

description: We present a quantum-cascade emitter in the galliumarsenide/aluminum–galliumarsenide (GaAs/AlGaAs) heterosystem whose emission properties are controlled by an additional electric field perpendicular to the transport direction. In our case, the additional field is established by remote delta-silicon doping, which is also responsible for charge carrier supply. The field originating from the delta-doping gives rise to an in-plane confinement creating a quantum-wire cascade. This field-effect quantum-cascade emitter is realized using the cleaved edge overgrowth method. Radiative electronic transitions between discrete energy levels in coupled quantum wires were calculated for such a structure. Without an additional electric field, no significant transport is observed. With a field applied, midinfrared emission is observed at a peak wave number of 1200 cm–1 with a full width at half maximum of 300 cm–1 for a heat-sink temperature of 20 K. The presented sample is an experimental proposal for a unipolar quantum-wire intersubband laser.

Мастилоуловлювач потужних електричних машин належить до важкого електромашинобудування. Мастилоуловлювач, що складається зі звареного металевого корпусу, який має роз'єм по горизонтальній осі, фланці якого сполучаються болтовим з'єднанням. Маслоуловлювач виконаний таким чином, що створює пустотілу кільцеву камеру, доступ до якої наявний на внутрішньому діаметрі мастилоуловлювача. При цьому в нижній точці камери виконаний перший циліндричний отвір, який розташований горизонтально, в стінці, яка примикає до підшипника турбогенератора. На внутрішньому діаметрі корпусу встановлені ущільнювальні гребінці, закріплені в ньому карбуванням і потайними гвинтами. При цьому в нижній частині корпусу між гребінцями виконані циліндричні отвори, які з'єднують зовнішній простір корпусу мастилоуловлювача з його камерою. В запропонованій конструкції корпус виконаний з додатковою камерою, аналогічною основній, яка розташована на стороні маслоуловлювача, протилежній від підшипника турбогенератора. Мастилоуловлювач згаданої конструкції, в якому в бічній стінці нижньої частини додаткової камери виконано другий циліндричний отвір, з'єднуючий її з основною камерою. При цьому в нижній частині основної камери в протилежній стінці виконаний другий отвір більшим діаметром, ніж перший. Використання запропонованої конструкції знизить величину протікання масла, що проходить через гребінці ущільнень мастилоуловлювача, здійснить ефективний відвід масла з міжгребінцевого простору і камер мастилоуловлювача. Мастилоуловлювач потужних електричних машин належить до області електромашинобудування, зокрема до мастилоуловлювачів крупних електричних машин, наприклад турбогенераторів.

description: We present work on single and double quantum dots which have been defined in the two-dimensional electron gas of a freely suspended GaAs/AlGaAs heterostructure. The dots are formed either by pairs of etched constrictions or by gating electrodes and characterized in Coulomb blockade measurements. Because of their small overall dimensions the suspended dots constitute phonon cavities in which electron transport is strongly modified by electron–phonon interaction. Our measurements indicate that the emission of phonons suppresses linear transport in the Coulomb blockade regime. Upon application of a perpendicular magnetic field Coulomb blockade oscillations reemerge, as well as under nonlinear transport conditions.

description: This work is focused on the doubly nonlinear equation, whose solutions represent the bending motion of an extensible, elastic bridge suspended by continuously distributed cables which are flexible and elastic with stiffness k^2. When the ends are pinned, long-term dynamics is scrutinized for arbitrary values of axial load p and stiffness k^2. For a general external source f, we prove the existence of bounded absorbing sets.When f is timeindependent, the related semigroup of solutions is shown to possess the global attractor of optimal regularity and its characterization is given in terms of the steady states of the problem.

description: Mid-infrared electroluminescence (EL) is observed from multiperiod bilayer type-II InAs/AlGaSb structures with the effective interlayer separation controlled by bias. The emission with powers in the microwatt range is characterized by a linear dependence of the photon energy on the bias. By measuring the temperature and current dependence of EL, we find evidence that the EL emission results from recombination of holes in AlGaSb quantum wells (QWs) with electrons occupying two different quantum states in InAs QWs.

Experimental and numerical analysis of semi-solid constitutive behaviour of B206 and A356 foundry alloys
Creators: name: Sheykhjaberi, Fariba

description: Aluminum foundry alloys are used for a wide range of industrial applications. Hot tearing is often a challenging casting defect in aluminum alloys, occurring in the semi-solid state, which has a substantial impact on the quality of casting products. The constitutive response of the semi-solid material to deformation is crucial for controlling hot tear formation, and thus it is necessary to have a means of assessing a semi-solid’s constitutive behaviour, and the role of microstructure in deforming this two-phase medium. The semi-solid tensile behaviour of two commercially used foundry aluminum alloys was experimentally characterized using a Gleeble thermo-mechanical test apparatus and numerically characterized using a multi-physics numerical model. First, thermo-mechanical testing was carried out on samples prepared by chill wedge-shaped casting. The test results indicated that at relatively high fraction solid (fs=0.95-1), B206 has higher yield stress than A356. However, at lower fraction solids (fs<0.95), A356 has been shown to have higher yield stress. The minimum fraction solid when the yield stress reaches very low values (almost zero), known as rigidity point, are shown to be 0.93 and 0.80 for B206 and A356, respectively. Second, the combined effects of deformation, fluid flow, and microstructure were studied using a multi-physics granular microstructure model. Using feedable and unfeedable microstructure models, the effect of feeding of the semi-solid pressure drop was studied. Unfeedable domains with different microstructures including equiaxed globular, equiaxed dendritic, and combined dendritic and eutectic were developed. Considering that lack of liquid feeding and semi-solid deformation are the well-known contributors to the hot tearing formation, the effect of feeding and mechanical deformation were studied and discussed. The model demonstrated that the microstructure type and the eutectic formation also have a considerable effect on the liquid channels pressure drop and semi-solid bulk stress and strain, and consequently on hot tearing. Then, the obtained experimental and numerical results were used to assess the hot tearing susceptibility of A356 and B206. Both experimental and numerical results showed that B206 is more susceptible to hot tearing. However, hot tearing could occur in A356 as well if feeding is limited.

description: We report on the dramatic evolution of the quantum Hall ferromagnet in the fractional quantum Hall regime at ν=2/5 filling. A large enhancement in the characteristic time scale gives rise to a dynamical transition into a novel quantized Hall state. The observed Hall state is determined to be a zero-temperature phase distinct from the spin-polarized and spin-unpolarized ν=2/5 fractional quantum Hall states. It is characterized by a strong temperature dependence and puzzling correlation between temperature and time.

description: We present a generalization of the Next-to-Minimal Supersymmetric Standard Model (NMSSM), with an explicit mu-term and a supersymmetric mass for the singlet superfield, as a route to alleviating the little hierarchy problem of the Minimal Supersymmetric Standard Model (MSSM). Though this model does not address the mu-problem of the MSSM, we are able to generate masses for the lightest neutral Higgs boson up to 140 GeV with top squarks below the TeV scale, all couplings perturbative to the gauge unification scale, and with no need to fine tune parameters in the scalar potential. This model, which we call the S-MSSM, more closely resembles the MSSM phenomenologically than the NMSSM as usually defined.

description: The operation principle and preliminary results of a novel gas-avalanche patterned hole electron multiplier, the Thick-COBRA (THCOBRA), are presented. This micro-hole structure is derived from the THGEM and MHSP. Sub-millimeter diameter holes are mechanically drilled in a thin G10 plate, Cu-clad on both faces; on one of the faces the Cu is etched to produce additional anode strips winding between circular cathode strips. Primary avalanches occurring within the holes are followed by additional ones at the anode-strips vicinity. Gains in excess of 5*104 were reached with 22.1 x-rays in Ar, Ne and Ar-10%CH4, with 12.2 % FWHM energy resolution in Ar-10%CH4. Higher gains were measured with single photoelectrons. This robust multiplier may have numerous potential applications.
