description: We review lattice determinations of the charm and bottom quark masses and the strong coupling constant obtained by different methods. We explain how effective field theory approaches, such as Non-Relativistic QCD (NRQCD), potential Non-Relativistic QCD (pNRQCD), Heavy Quark Effective Theory (HQET) and Heavy Meson rooted All-Staggered Chiral Perturbation Theory (HMrAS$χ$PT) can help in these determinations. After critically reviewing different lattice results we determine lattice world averages for the strong coupling constant, $α_s(M_Z,N_f{=}5)=0.11803^{+0.00047}_{-0.00068}$, as well as for the charm quark mass, $m_c(m_c,N_f{=}4)=1.2735(35)$ GeV, and the bottom quark mass, $m_b(m_b,N_f{=}5)=4.188(10)$ GeV. The above determinations are more precise than the ones obtained by Particle Data Group (PDG).

title: What would Newly Qualified Teachers appointed in Cyprus Primary Schools expect from an effective school-based induction programme? Recommendations for the introduction of an effective school-based induction programme
Creators: name: Panteli, Marios Anthimou
Publisher: name: The Open University
Year: 2009

description: This study investigates the induction of Newly Qualified Teachers (NQTs) in Cyprus Primary Education. In Cyprus, until September 2008, there was no formal induction policy for primary teachers. However, since June 2006, after the beginning of this study, the issue of inducting and evaluating NQTs has been extensively discussed in the context of the discussions about Educational Reform. The key purpose of the study was to make recommendations for the introduction of effective school-based induction activities/strategies for NQTs appointed in Cyprus Primary Education by identifying their needs and exploring their expectations of a school-based induction programme. The type of research approach selected was that of mixed methods research taking into account that it combined the use of both qualitative and quantitative research methods. The following data collecting instruments were used: a focus group interview with NQTs: postal questionnaires sent to NQTs: face to face interviews with NQTs; and e mail interviews with an NQT and the Minister of Education and Culture. The study used a national representative sample because its intention was to generalise the findings for the whole target population. According to the NQTs in my sample responses. NQTs appointed in Cyprus Primary Education are thrown in at the deep end, with a full teaching load and associated responsibilities with limited support. They also encounter many problems during the first years of teaching. Therefore, the NQTs argued that every school should implement an individual structured programme of support for all beginning teachers in order to help them overcome the specific problems they face. The induction programme must directly address NQTs' specific needs and concerns, must be flexible and should be negotiated on the basis of individual needs and goals. NQTs also underlined that the induction programme should serve several purposes and include many induction activities and opportunities of support. What they needed desperately was the presence of regular and structured guidance and support mainly from a mentor. In summary, based upon the findings, this study provides valuable information for determining which school-based strategies are likely to be useful and effective for Cyprus Primary NQTs.

description: As a result of a radial velocity follow-up of OGLE planetary transit candidates in Carina, we report the discovery of two new transiting planets with very short orbital periods: OGLE-TR-113 with m=1.35+-0.22 M_{Jup}, r=1.08 {+0.07}{-0.05} R_{Jup}, P=1.43 day, and OGLE-TR-132 with m=1.01+-0.31 M_{Jup}, r=1.15 {+0.80}{-0.13} R_{Jup}, P=1.69 day. These detections bring to three the number of known "very hot Jupiters" (Jovian exoplanets like OGLE-TR-56 with periods much smaller than 3 days), indicating that the absence of such planets in radial velocity survey does not reflect an absolute limit.

description: We present the first implementation of the Cho--Faddeev--Niemi decomposition of the SU(2) Yang-Mills field on a lattice. Our construction retains the color symmetry (global SU(2) gauge invariance) even after a new type of Maximally Abelian gauge, as explicitly demonstrated by numerical simulations. Moreover, we propose a gauge-invariant definition of the magnetic monopole current using this formulation and compare the new definition with the conventional one by DeGrand and Toussaint to exhibit its validity.

title: An Ethnographic Case Study exploring the use of Reflective Learning by Trainee Nurse Mentors
Creators: name: Miklaucich, Maria
Publisher: name: The Open University
Year: 2010

description: This is an ethnographic case study undertaken to investigate learning through the use of reflection and reflective practice frameworks within a programme training nurses to be mentors. The conceptual underpinning for the research originates from the work of Schon (1987 & 1983) and Johns (1993-2006). The aim of the study was to discover the extent to which the nurses' learning was influenced by reflection and reflective practice. I wanted to know how the use of the concepts promoted learning for the trainee's enabling them to develop as mentors and fulfil their educational requirements for continual professional development. Lather's (1991 & 1986) ideas of research as praxis are utilised to enable me to solve problems, develop the trainee mentors and the mentor curricula as part of the research process. I gain insight to the nurses' use and processes of reflection and reflective practice by interviewing each participant and obtaining their written reflective accounts of learning undertaken during the mentor programme. I also conducted participant observation in class and non participant observation in the practice environments which I later deconstructed. I analyse the textual accounts via the ethnographic approach of grounded theory as described by Strauss and Corbin (1998). A total of fifteen qualified nurses participated in the study. I carried out the research during the period 2003-2006. The research setting was a University, one acute National Health Service Hospital Trust, and one independent Hospital. I discovered that the use of reflection and reflective practice is a process represented by the participant trainee mentors as sequential layers of learning that developed as they journeyed through the mentor programme. The outcome of the research led to the development of a praxis theory of reflective learning. In relation to the work of Lather (1986) I also developed the research process as self advocacy.

description: We consider operator growth for generic large-N gauge theories at finite temperature. Our analysis is performed in terms of Fourier modes, which do not mix with other operators as time evolves, and whose correlation functions are determined by their two-point functions alone, at leading order in the large-N limit. The algebra of these modes allows for a simple analysis of the operators with whom the initial operator mixes over time, and guarantees the existence of boundary CFT operators closing the bulk Poincaré algebra, describing the experience of infalling observers. We discuss several existing approaches to operator growth, such as number operators, proper energies, the many-body recursion method, quantum circuit complexity, and comment on its relation to classical chaos in black hole dynamics. The analysis evades the bulk vs boundary dichotomy and shows that all such approaches are the same at both sides of the holographic duality, a statement that simply rests on the equality between operator evolution itself. In the way, we show all these approaches have a natural formulation in terms of the Gelfand-Naimark-Segal (GNS) construction, which maps operator evolution to a more conventional quantum state evolution, and provides an extension of the notion of operator growth to QFT.

description: The first time I used ATLAS.ti was during my master’s program. Part of the program was to take a course that would benefit faculty members, students at the college and other nursing college back home on my return through capacity building. Therefore, learning about ATLAS.ti was ideal as it had not yet been introduced at the college in 2002. The model used to acquire knowledge and skills of ATLAS.ti was the participatory empowerment model by Fetterman. This was to be realized by enrolling in an ATLAS.ti course, practice using different data sets as well as mentor at least four people on my return home to evaluate my knowledge and skills. The first experience was when I used the software to analyse data of my thesis. The major benefit noted was that the software directs the researcher, through use of different types of codes that enhances formulation of categories and themes, thus reducing time used to analyse data manually. At college level it meant sharing of new knowledge on data management which is congruent with the academic tradition. The challenges were lack of adequate software; technical support and time to practice. Based on my experience, I recommend that knowledge and skills of ATLAS.ti are important in this era of technology and when working at a higher institution of learning. The college needs to build capacity and encourage faculty to know and use this software.

description: Using exact diagonalization of bilayer quantum Hall systems at total filling factor $ν_T=1$ in the torus geometry, we show that there is a new long-range interlayer phase coherence due to spontaneous pseudospin spiral order at interlayer distances larger than the critical value at which the pseudospin ferromagnetic order is destroyed. We emphasize the distinction between the interlayer phase coherence and the pseudospin ferromagnetic order.

description: U .S. food manufacturers supply their products to foreign consumers primarily through local production in foreign markets. In fact, exports pale in comparison to sales by foreign affiliates of U.S. firms. In 1992, processed food sales from U.S.-owned foreign affiliates totaled $89 billion- almost four times U.S. export sales of processed foods. And while U.S. exports of processed foods continued to grow, the gap between them and foreign affiliate sales more than doubled between 1982 and 1992 (fig. 1). Foreign production also occurs through licenses between U.S. and foreign firms. These agreements allow foreign firms to produce and sell the U.S. firms' products in specified foreign markets (see "International Licensing of Foods and Beverages Makes Markets Truly Global," elsewhere in this issue).
Narrowband large amplitude whistler-mode waves in the solar wind and their association with electrons: STEREO waveform capture observations

description: Large amplitude whistler waves at frequencies of 0.2 to 0.4 times electron cyclotron frequency are frequently observed in the solar wind. The waves are obliquely propagating close to the resonance cone, with significant electric fields parallel to the background magnetic field, enabling strong interactions with electrons. Propagation angles are distinctly different from whistlers usually observed in the solar wind, and amplitudes are significantly larger. Waves occur most often in association with stream interaction regions (SIRs), and are often close-packed. 68 percent of the 54 SIRs had narrowband whistler groups; 33 percent of the nine interplanetary coronal mass ejections had coherent groups. Although wave occurrence as a function of the electron temperature anisotropy and parallel beta is constrained by the thresholds for the whistler temperature anisotropy and firehose instabilities, neither is consistent with observed wave properties. We show for the first time that comparisons of wave data to thresholds for the electron beam driven instability (beam speed greater than twice the electron Alfven speed) and to the whistler heat flux fan instability indicate that either might destabilize the narrowband waves. In contrast, the less coherent waves, on average, are associated with zero or near zero heat flux and much higher electron Alfven speeds, without higher energy beams. This suggests that the less coherent waves may be more effective in regulating the electron heat flux, or that the scattering and energization of solar wind electrons by the narrowband waves results in broadening of the waves. The highly oblique propagation and large amplitudes of both the narrowband and less coherent whistlers enable resonant interactions with electrons over a broad energy range, and, unlike parallel whistlers does not require that the electrons and waves counter-propagate.

description: U .S. exports of high-value agricultural products (HVP's) reached a record $24 billion in fiscal 1993, accounting for over half of total U.S. agricultural exports of $42.6 billion. Continuing the trend of surpassing bulk commodity exports since fiscal 1991, the gap has kept growing. In fiscal 1994, HVP exports probably topped $25 billion, with the margin between HVP and bulk exports expected to broaden to nearly $8 billion. But the growth has not been even among HVP's. "High-value" is a term given to a group of agricultural products, generally those with value added through processing (such as soybean oil) or because they require special handling or shipping (such as fresh fruit). High-value products can be grouped into two categories-intermediate commodities and consumer food products. Intermediate commodities are those that have been partially processed (such as soybean meal and cattle hides) or those used as inputs on the farm (such as seeds and animal feeds) or used by food manufacturers (such as flour and sweeteners).Consumer food products are primarily shipped for consumption in the retail market and foodservice sectors in the importing country. These include highly processed foods and beverages (such as condiments, wine and beer, processed meats, and frozen dinners) and less processed foods (such as fresh fruit, vegetables, and meats). (Fish, seafood, and distilled liquor exports are not included in this data set.)

description: Quantum algorithms for graph problems are considered, both in the adjacency matrix model and in an adjacency list-like array model. We give almost tight lower and upper bounds for the bounded error quantum query complexity of Connectivity, Strong Connectivity, Minimum Spanning Tree, and Single Source Shortest Paths. For example we show that the query complexity of Minimum Spanning Tree is in Theta(n^{3/2}) in the matrix model and in Theta(sqrt{nm}) in the array model, while the complexity of Connectivity is also in Theta(n^{3/2}) in the matrix model, but in Theta(n) in the array model. The upper bounds utilize search procedures for finding minima of functions under various conditions.

Tidal effects on magnetic gyration of a charged particle in Fermi coordinates

description: We examine the gyration motion of a charged particle, viewed from a reference observer falling along the Z axis into a Schwarzschild black hole. It is assumed that the magnetic field is constant and uniform along the Z axis, and that the particle has a circular orbit in the X-Y plane far from the gravitational source. When the particle as well as the reference observer approaches the black hole, its orbit is disrupted by the tidal force. The final plunging velocity increases in the non-relativistic case, but decreases if the initial circular velocity exceeds a critical value, which is approximately 0.7c. This toy model suggests that disruption of a rapidly rotating star due to a velocity-dependent tidal force may be quite different from that of a non-relativistic star. The model also suggested that collapse of the orbit after the disruption is slow in general, so that the particle subsequently escapes outside the valid Fermi coordinates.

description: Economic development is a process whereby the real per capita income of a country is increased and sustained over a long , period of time subject to some caveats. First, this process is subject to the stipulations that the number below the absolute poverty line does not increase and that the distribution of income does not become more unequal (Meier, 1976 and Aboyade, 1976). Second, such a process must experience some elements .of modernisation such as enhanced productivity, social and economic equalisation; improved knowledge, attitudes and institutions; and rationally coordinated policy measures that are capable of removing all obstacles to socio-economic transformation (Abciyade, 1976; Obadart, 1998; Ohiorhenuan, 2000). The World Summit for Social Development held in Copenhagen in 1995 and its follow-up in June 2000 added yet another caveat which is to popularise the human dimension of the issue. With this caveat, human beings are placed at the core of any meaningful economic development. They are the means and ends of economic development. As clearly evident in Nigeria's development documents, the primary goal of economic development policies has been geared towards the actualisation of a solid base for long-term economic and social transformation of the country with a view to establishing peace, progress and prosperity. The realisation of this laudable objective informed the adoption of several economic policies and strategies . in the country. Since independence, economic development policies have been very dynamic. Between 1960 and 1985, government thought that a fixed medium-term National Development Plan framework would transform Nigeria into the type of society it envisaged. The economic crisis of the early 1980s clearly showed the futility of this approach in the Nigerian context. This, therefore, led to the adoption of a comprehensive Structural Adjustment Programme (SAP) which emphasised a policybased economic management strategy (1986 - 1990). After more than five years of implementing SAP, it became obvious that its performance was mixed and . tilted towards nonaccomplishment of its major objectivesJ The adoption of a three-tier planning system since 1990, a framework that comprises a perspective plan, a three-year rolling plan and an annual budget, also left much to be desired in terms of achieving its goals.

description: Planning a motion for inserting pegs remains an open problem. The difficulty lies in both the inevitable errors in the grasps of a robotic hand and absolute precision problems in robot joint motors. This paper proposes an integral method to solve the problem. The method uses combined task and motion planning to plan the grasps and motion for a dual-arm robot to pick up the objects and move them to assembly poses. Then, it controls the dual-arm robot using a compliant strategy (a combination of linear search, spiral search, and impedance control) to finish up the insertion. The method is implemented on a dual-arm Universal Robots 3 robot. Six objects, including a connector with fifteen peg-in-hole pairs for detailed analysis and other five objects with different contours of pegs and holes for additional validation, were tested by the robot. Experimental results show reasonable force-torque signal changes and end-effector position changes. The proposed method exhibits high robustness and high fidelity in successfully conducting planned peg-in-hole tasks.

description: Here we report on a two year continuous survey to examine possible VLF signals associated with meteors brighter than magnitude -5. Our survey allowed both calibrated temporal and spatial correlations between VLF signals and fireball lightcurves. We used continuous observations from the Atmospheric Weather Electromagnetic System for Observation Modeling and Education (AWESOME) VLF receiver system (Cohen et al., 2010) deployed at the Elginfield Observatory near London, Ontario, Canada (43N, 81W) to monitor VLF radio signals and correlate with all-sky video recordings of fireballs. This survey from May 2017 to March 2019 was cued using fireballs detected by the Southern Ontario Meteor Network (Brown et al., 2010; Weryk et al., 2007). The GPS conditioned timing of the AWESOME system was continuously synchronized with video recordings directly in the video stream to ensure sub-frame VLF-optical time calibration. The AWESOME system has two orthogonal VLF antennas which permits directional calculation of incoming VLF signals, which were compared to the apparent optically measured locations of simultaneously detected fireballs. VLF events potentially linked to fireballs were checked against the National Lightning Detection Network (NLDN) database to remove false positive association with lightning. During the two year survey interval, over 80 bright meteors (apparent magnitude brighter than -5, brightest recorded event -7.8) were detected and compared to VLF signals detected by the AWESOME system. No definitive evidence was found for VLF emission from meteors up to a limiting magnitude of -7.8.

description: This paper examines the impact of temperature and rainfall volatility on economic growth in 46 African countries. We employ the Bayesian hierarchical modeling approach which allows us to estimate both country level and Africa-wide impact of climate change and extreme events on economic growth in Africa. Our results show that a 10 Celsius increase in temperature leads to 1.58 percentage points decline in economic growth while temperature shock reduces economic growth by 3.22 percentage points. A 1 percent change or shock in rainfall leads to a 6.7 percent change in economic growth. The impact of temperature changes across the 46 countries ranges from -1.24 percent to -1.82 percent in GDP. There are proximity effects on the impact. To maximize the benefits of economies of scale, the paper suggests combined national, cross countries and continental approaches to climate change adaptation in Africa.

description: In patriarchal societies like Nigeria, where traditional norms and practices limits women's autonomous decisions on issues that affect their lives; men exercise significant influence on household decision-making processes. However, due to the economic crisis of the early 1980s and the associated worsening poverty, men’s resources are increasingly becoming inadequate to meet the various needs of their households. Consequently, women’s contribution to family resources has increased remarkably. To what extent has poverty affected women’s participation in household decision-making? This paper tries to answer this question. Using a non-income poverty measurement (social exclusion), the study employed descriptive and analytical methods of analysis with particular attention focused on women between the ages of 25 and 49 years got married before SAP was introduced. Evidence from the study reveals a high level of impoverishment using non-income indices. The results indicate that a fairly high proportion of women are involved in household decision-making. Women participated more on household matters in pre-SAP than post-SAP era. However, poor women participate less in household decision-making relative to non-poor during post SAP era. The predominant factors are women’s education, women’s employment status, religion, and husband’s educational attainment. The results also portray a shift away from patriarchal tendencies to an egalitarian one where partnerships and collective interactions predominate. Some policy considerations include need to mainstream gender targeting in poverty eradication, if women’s family decision authority is to be meaningfully enhanced, as well as the need to ensure gender responsive budgeting in development management, promotion of improved women’s education and women’s gainful employment in higher income generation sectors.

description: The first year data from the Wilkinson Microwave Anisotropy Probe are used to place stringent constraints on the topology of the Universe. We search for pairs of circles on the sky with similar temperature patterns along each circle. We restrict the search to back-to-back circle pairs, and to nearly back-to-back circle pairs, as this covers the majority of the topologies that one might hope to detect in a nearly flat universe. We do not find any matched circles with radius greater than 25 degrees. For a wide class of models, the non-detection rules out the possibility that we live in a universe with topology scale smaller than 24 Gpc.

description: Over the past five decades, substantial attention has been placed on the role of economic growth in reducing poverty. This is premised on the trickle-down effect of long-term economic growth on poverty and inequality, based on Simon Kuznets’ theory. However, evidence across the world has shown that high economic growth and rapid reduction in poverty do not automatically translate into accelerated reduction in inequality (Stiglitz, 2015; Reid-Henry, 2015; Piketty, 2015). China and Rwanda provide some good examples of the lack of trickle-down effect on inequality where rapid economic growth has been accompanied by rising income inequality. The global inequality crisis – where the richest 1 per cent of the world’s population has more wealth than the rest of the world combined – has disproved Kuznets’ theory and has further questioned the efficacy of fiscal policies in promoting economic efficiency and development effectiveness.

description: Excitons with binding energies of a few hundreds of meV control the optical properties of transition metal dichalcogenide monolayers. Knowledge of the fine structure of these excitons is therefore essential to understand the optoelectronic properties of these 2D materials. Here we measure the exciton fine structure of MoS2 and MoSe2 monolayers encapsulated in boron nitride by magneto-photoluminescence spectroscopy in magnetic fields up to 30 T. The experiments performed in transverse magnetic field reveal a brightening of the spin-forbidden dark excitons in MoS2 monolayer: we find that the dark excitons appear at 14 meV below the bright ones. Measurements performed in tilted magnetic field provide a conceivable description of the neutral exciton fine structure. The experimental results are in agreement with a model taking into account the effect of the exchange interaction on both the bright and dark exciton states as well as the interaction with the magnetic field.

description: We demonstrate efficient multicycle terahertz pulse generation at 14.6 THz from large-area lithium niobate crystals by using high-energy (up to 2 J) femtosecond Ti:sapphire laser pulses. Such terahertz radiation is produced by phase-matched optical rectification in lithium niobate. Experimentally, we achieve maximal terahertz energy of 0.71 mJ with conversion efficiency of $\sim$0.04%. We also find that the effective interaction length for optimal terahertz conversion is fundamentally limited by terahertz absorption, laser pulse stretching by material dispersion, and terahertz-induced nonlinear cascading effects on the driving laser pulse.

description: A tunnel barrier in a degenerate electron gas was recently discovered as a source of entangled electron-hole pairs. Here, we investigate the loss of entanglement by dephasing. We calculate both the maximal violation E_max of the Bell inequality and the degree of entanglement (concurrence) C. If the initially maximally entangled electron-hole pair is in a Bell state, then the Bell inequality is violated for arbitrary strong dephasing. The same relation E_max=2\sqrt{1+C^{2}} then holds as in the absence of dephasing. More generally, for a maximally entangled superposition of Bell states, the Bell inequality is satisfied for a finite dephasing strength and the entanglement vanishes for somewhat stronger (but still finite) dephasing strength. There is then no one-to-one relation between E_max and C.

Black Hole Production in Particle Collisions and Higher Curvature Gravity

description: The problem of black hole production in transplanckian particle collisions is revisited, in the context of large extra dimensions scenarios of TeV-scale gravity. The validity of the standard description of this process (two colliding Aichelburg-Sexl shock waves in classical Einstein gravity) is questioned. It is observed that the classical spacetime has large curvature along the transverse collision plane, as signaled by the curvature invariant (R_ijkl)^2. Thus quantum gravity effects, and in particular higher curvature corrections to the Einstein gravity, cannot be ignored. To give a specific example of what may happen, the collision is re-analyzed in the Einstein-Lanczos-Lovelock gravity theory, which modifies the Einstein-Hilbert Lagrangian by adding a particular `Gauss-Bonnet' combination of curvature squared terms. The analysis uses a series of approximations, which reduce the field equations to a tractable second order nonlinear PDE of the Monge-Ampere type. It is found that the resulting spacetime is significantly different from the pure Einstein case in the future of the transverse collision plane. These considerations cast serious doubts on the geometric cross section estimate, which is based on the classical Einstein gravity description of the black hole production process.
