title: Exploring Transformative Journeys through a Higher Education Programme in a Further Education College
Creators: name: Rocks, Eddie
Publisher: name: The Open University
Year: 2017

description: Since the 1960s, there has been a sustained policy commitment to widen participation to social groups previously under-represented in further and higher education (Thompson, 2000; Burke, 2012). Widening participation has encouraged students to return who are poorly prepared for the intellectual challenges of post-compulsory education (Leatherwood, 2005; Burton and Golding Lloyd et al, 2011). Some research has concluded that post-compulsory education has been dumbed down to accommodate ill-prepared students (Haggis, 2006; Coffield, 2010). This research interrogates these analyses in the context of Higher Education in Further Education (HE in FE). The research investigates if HE in FE can be a catalyst for significant social, emotional, and intellectual growth in students – if students can be transformed by the experience of education (Mezirow, 1978a, 1991; Cranton, 2006). Within both a critical and a phenomenological research paradigm, twelve non-traditional graduates from a full-time BA programme at an HE and FE College in Scotland were interviewed; as were the BA programme leader and a module teacher. The graduates also produced reflections of their experiences of HE in FE. The research sought to determine if graduates from HE in FE can experience significant social, emotional, and intellectual growth as a result of participation; what teaching and learning settings make this possible, and can graduates be transformed by the experience of HE in FE? The findings of the research indicate that the participants, to varying degrees, all experienced some significant shift in attributes such as confidence, independence and willingness to try new things. How they experience, conceptualise and participate in their social worlds has become more discriminating. I conclude by proposing that higher education programmes, facilitated in further and higher education colleges, can have the potential to provide transformative experiences for students who participate. It has been a transformative experience for the participants in this research.

description: We apply torque equilibrium spin wave theory (TESWT) to investigate an anisotropic XXZ antiferromagnetic model with Dzyaloshinskii-Moriya (DM) interaction in a triangular lattice. Considering the quasiparticle vacuum as our reference, we provide an accurate analysis of the non-collinear ground state of a frustrated triangular lattice magnet using the TESWT formalism. We elucidate the effects of quantum fluctuations on the ordering wave vector based on model system parameters. We study the single magnon dispersion, the two-magnon continuum using the spectral function, and the Raman spectrum of bimagnon and trimagnon excitations. We present our results for the $HH, VV$, and the $HV$ polarization Raman geometry dependence of the bimagnon and the trimagnon excitation spectrum where $H (V)$ represents horizontal (vertical) polarization. Our calculations show that both the $HH$ and the $HV$ polarization spectrum can be used to determine the degree of anisotropy of our system. We calculate the Raman spectra of Ba$_3$CoSb$_2$O$_9$ and Cs$_2$CuCl$_4$.

description: We present tunneling and rattling motions of an off-center guest atom in cage referring to a clathrate crystal La_3Pd_{20}Ge_6. The elastic constant C_{44} of La_3Pd_{20}Ge_6 shows a Debye-type dispersion around 20 K obeying a relaxation time tau = tau_0exp(E/k_{B}T) with an attempt time tau_0 = 2.0*10^{-12} sec and an activation energy E = 197 K. At low temperatures below 3 K down to 20 mK, the C_{44} shows a softening of C_{44} = C_{44}^0(T-T_C^0)/(T-Theta) with T_C^0 = -337.970 mK and Theta = -338.044 mK. These facts are attributed to two different types of the off-center motions with Gamma_5 symmetry in 4a-site cage of La_3Pd_{20}Ge_6, a thermally activated rattling motion over the potential hill and a tunneling motion through the potential hill at low temperatures.

description: The aim was to formulate and evaluate, from the point of view and with private financing through government subsidy, a proposal for an additional investment business tilapia. The research was conducted in a region of the municipality of Amatepec, State of Mexico, from May to October 2014, in which information was seen coming from a farm producing tilapia species niloticus, to determine the effect of new investment government subsidy and fixed investment. Methodology development and evaluation of projects under certainty and uncertainty and sensitivity analysis of the situation with no less effect and without the project was used. The results made it possible to demonstrate the existence of commercial viability, technical and financial feasibility. With a discount rate of 12%, the profitability indicators without project were: 803.5% IRR and NPV 160.630 pesos, the project was 143.2% IRR and NPV 314.933 pesos; Furthermore, the effect of new investments (less free), generated an IRR of 75.8% and a NPV of 163.066 pesos. With the project, the tilapia business paid in 0.8 years and generated an additional profit of 314.933 pesos accumulated. The sensitivity analysis indicated that the business tilapia does not a selling price below 33 pesos per kilogram, or a lower level of sales to 2.4 t/year. We conclude that under the three scenarios, the tilapia business is profitable and its implementation is suggested. There was evidence that supports that tilapia business should leave its natural course and take advantage of new investment.

description: We introduce the idea of {\it collisional models} for Brownian particles, in which a particle is sequentially placed in contact with distinct thermal environments and external forces. Thermodynamic properties are exactly obtained, irrespective the number of reservoirs involved. In the presence of external forces, entropy production presents a bilinear form in which Onsager coefficients are exactly calculated. Analysis of Brownian engines based on sequential thermal switchings is proposed and considerations about their efficiencies are investigated taking into account distinct external forces protocols. Our results shed light to a new (and alternative) route for obtaining efficient thermal engines based on finite times Brownian machines.

description: We report a way of obtaining a spin configuration snapshot, which is one of the representative spin configurations in canonical ensemble, in a finite area of infinite size two-dimensional (2D) classical lattice models. The corner transfer matrix renormalization group (CTMRG), a variant of the density matrix renormalization group (DMRG), is used for the numerical calculation. The matrix product structure of the variational state in CTMRG makes it possible to stochastically fix spins each by each according to the conditional probability with respect to its environment.

The limits of osmoregulation : strategies for tolerance and acclimation of 'California' Mozambique tilapia (Oreochromis mossambicus x O. urolepis hormorum) to conditions of the Salton Sea
Creators: name: Sardella, Brian
Publisher: name: University of British Columbia
Year: 2011

description: The Salton Sea is a large inland lake in southeastern California with salinity currently near 44 g/l that is increasing at a rate of 0.3 g/l annually. Along with salinity, large fluctuations in temperature and dissolved oxygen levels combine to make a very challenging environment that may be responsible for dramatic losses to the Salton Sea's once robust fishery. The dominant species within the fishery is a Mozambique tilapia hybrid (Oreochromis mossambicus x O. urolepis hornorum), which is well known both for euryhalinity and tolerance of extremely high salinities; as such, it provides a unique model for tolerance to hypersaline conditions as well as the interactions of multiple stressors such as those within the Salton Sea. In part one I describe two responses by tilapia to salinities greater than seawater at 25°C. When transfers were conducted below 60 g/l salinity, tilapia maintained osmotic balance without increasing drinking rate, mitochondrial-rich cell (MRC) turnover, or branchial Na⁺,K⁺-ATPase (NKA) activity. With additional increase above 60 g/l, these variables increased in similar fashion to that which has been described in other teleosts during acclimation to elevated salinity. These acclimation responses were defined as response I or response II, with a transition point between the two at 60 g/l. Tilapia exhibiting response I had a reduced whole animal oxygen consumption rate, as well as, liver and brain ATPase activity in proportion to salinity. In part two, I describe how changes in temperature affect the salinity tolerance of this species. Variation in temperature from 25°C to 15 or 35°C resulted in increased plasma osmolality and/or mortality, indicating a combined temperature/salinity stress is more challenging than salinity alone. Using tissue microarrays and laser scanning microscopy, I show that tilapia attempted to respond to the loss of osmotic balance in cold temperatures with MRC hypertrophy and enhanced NKA capacity.

description: This article is intended to discuss aspects of enterprise social networks for collaboration among actors in a territory of Chiapas, where the tomato production represents an activity that generates substantial revenue for the families of the main tomato-producing area in the State: the Comiteca Plateu (part of the territory of the municipalities of Comitan, La Trinitaria, La Independencia y Las Margaritas). The main tool of data analysis is the analysis of social networks-ARS (for its acronym in Spanish). Apart from the intuition of the researcher and the metaphor of the network, calculations with specialized software allow to clearly identify key players and the nature of the linkages established in the economic activity that is common to them. In their different interests and motivations, actors interface among them for different purposes, which define the nature of the relationship bond. Collaboration and learning are some of the reasons why agribusinessmen, specifically producers, establish ties with other. Relationships for collaboration is disaggregate in subnets, giving rise to different schemes on which rest the enterprise networks.

description: We calculate, at the one loop level, penguin diagrams for improved staggered fermion operators constructed using various fat links. The main result is that diagonal mixing coefficients with penguin operators are identical between the unimproved operators and the improved operators using such fat links as Fat7, Fat7+Lepage, $\bar{\rm Fat7}$, HYP (I) and HYP (II). In addition, it turns out that the off-diagonal mixing vanishes for those constructed using fat links of Fat7, $\bar{\rm Fat7}$ and HYP (II). This is a consequence of the the fact that the improvement by various fat links changes only the mixing with higher dimension operators and off-diagonal operators. The results of this paper, combined with those for current-current diagrams, provide the complete matching at the one loop level with all corrections of ${\cal O}(g^2)$ included.

description: The average maize area produced under rainfed conditions, between 2007 and 2013, in the Yucatan Peninsula was 372,293 hectares. 41.94% was planted in the state of Campeche and 39.34% and 18.72% in Yucatán and Quintana Roo states respectively (SIAP, 2013). However, studies by the National Research System (INIFAP) with satellite images and field verification (from 2010 to 2013), identified just 197,108 hectares devoted to growing corn in the same region where the state of Campeche covered 63.42% of the total identified surface (Cano et al., 2013). Despite the importance of maize to the farmers there is no enough information related to the conventional farming systems to be analyzed in terms, not only, on yield but on production costs and net income. Therefore this work aimed to technically and economically evaluate the maize production systems located in the Yucatan Peninsula where 43 sites were selected and a direct interview to farmers were applied. The yield was estimated on field, considering agronomic variables using INIFAP methodology and the total cost of technology, total income, profitability, cost-benefit, cost-effectiveness and private efficiency was calculated. Data were analyzed using the Statistical Package Software and Predictive Analytical Solut (PASS) version 21. Levene test for homogeneity of variance was conducted contrasting the hypothesis (H0: and the ANOVA test, maintaining the hypothesis (H0:μ1 = μ2 = μ3), was used to compare means and identify significant differences by state and type of farmer. No significant differences between the age and education of producers were found, but differences were found among the experience of producers; the farmers of Campeche being more experienced, with 32 years, than the others. Statistical analysis concluded no significant difference between total production costs among states and, therefore, the production costs of technology in the whole Yucatan Peninsula were set at $ 6,448.93 per hectare. The total income per hectare was similar in the three states ($ 9,149.95); however the net income per hectare was higher in the state of Yucatán ($ 3,172.15) due to better price of grain rather than yield increases. Economic indicators (profitability, cost-benefit and economic efficiency) drove to the conclusion that corn farmers of the Yucatan Peninsula are cost effectives and economically efficient.
Confinement versus interface bound states in spin-orbit coupled nanowires

description: Semiconductor nanowires with strong Rashba spin-orbit coupling are currently on the spotlight of several research fields such as spintronics, topological materials and quantum computation. While most theoretical models assume an infinitely long nanowire, in actual experimental setups the nanowire has a finite length, is contacted to metallic electrodes and is partly covered by gates. By taking these effects into account through an inhomogeneous spin-orbit coupling profile, we show that in general two types of bound states arise in the nanowire, namely confinement bound states and interface bound states. The appearance of confinement bound states, related to the finite length of the nanowire, is favoured by a mismatch of the bulk band bottoms characterizing the lead and the nanowire, and occurs even in the absence of magnetic field. In contrast, an interface bound states may only appear if a magnetic field applied perpendicularly to the spin-orbit field direction overcomes a critical value, and is favoured by an alignment of the band bottoms of the two regions across the interface. We describe in details the emergence of these two types of bound states, pointing out their differences. Furthermore, we show that when a nanowire portion is covered by a gate the application of a magnetic field can change the nature of the electronic ground state from a confinement to an interface bound state, determining a redistribution of the electron charge.

description: We have studied the magnetic field dependence of the thermal conductivity $κ(T,B)$ of highly oriented pyrolytic graphite samples at temperatures 0.2K$ \le T < 10$K and fields 0T$ \le B \le 9$T. The samples show clear deviations from the Wiedemann-Franz law with a kink behavior at fields $B \sim 0.1 $T near the metal-insulator transition observed in electrical resistivity measurements. We further show that the oscillations in the thermal conductivity at the quantum limit $B > 1 $T, which are correlated with the Landau quantization observed in Hall measurements, increase in amplitude with temperature following a $\sim T^3$ law at $T > 0.2 $K and show a maximum at $T \sim 6 $K, suggesting that they are phonons mediated.

description: Spring 2020 broke sunshine duration records across western Europe. The Netherlands recorded the highest surface irradiance since 1928, exceeding the previous extreme of 2011 by 13 %, and the diffuse fraction of the irradiance measured a record low percentage (38 %). The coinciding irradiance extreme and a reduction in anthropogenic pollution due to COVID-19 measures triggered the hypothesis that cleaner-than-usual air contributed to the record. Based on analyses of ground-based and satellite observations and experiments with a radiative transfer model, we estimate a 1.3 % (2.3 W m$^{-2}$) increase in surface irradiance with respect to the 2010-2019 mean due to a low median aerosol optical depth, and a 17.6 % (30.7 W m$^{-2}$) increase due to several exceptionally dry days and a very low cloud fraction overall. Our analyses show that the reduced aerosols and contrails due to the COVID-19 measures are far less important in the irradiance record than the dry and particularly cloud-free weather.

description: We discuss the observability of circular polarisation of the stochastic gravitational-wave background (SGWB) generated by helical turbulence following a first-order cosmological phase transition, using a model that incorporates the effects of both direct and inverse energy cascades. We explore the strength of the gravitational-wave signal and the dependence of its polarisation on the helicity fraction, $ζ_*$, the strength of the transition, $α$, the bubble size, $R_*$, and the temperature, $T_*$, at which the transition finishes. We calculate the prospective signal-to-noise ratios of the SGWB strength and polarisation signals in the LISA experiment, exploring the parameter space in a way that is minimally sensitive to the underlying particle physics model. We find that discovery of SGWB polarisation is generally more challenging than measuring the total SGWB signal, but would be possible for appropriately strong transitions with large bubble sizes and a substantial polarisation fraction.

description: Using density functional based LDA+U method and linear-response theory, we study the magnetic exchange interactions of the superconductor Nd{1-x}Sr{x}NiO2. Our calculated nearest-neighbor exchange constant J1=82 meV is large, weakly affected by doping and is only slightly smaller than that found in the sister compound CaCuO2. We however find that the hole doping significantly enhances the inter--layer exchange coupling as it affects the magnetic moment of the Ni-3d{3z2-r2} orbital. This can be understood in terms of small hybridization of Ni-3d{3z2-r2} within the NiO2 plane which results in a flat band near the Fermi level, and its large overlap along z direction. We also demonstrate that the Nd-5d states appearing at the Fermi level, do not affect the magnetic exchange interactions, and thus may not participate in the superconductivity of this compound. Whereas many previous works emphasize the importance of the Ni-3d{x2-y2} and Nd-5d orbitals, we instead analyze the solution of Ni-3d{x2-y2}/Ni-3d{3z2-r2} minimal model using Dynamical Mean Field Theory. It reveals an underlying Mott insulating state which, depending on precise values of the intra--atomic Hund's coupling less or larger than 0.83 eV, selects upon doping either S=0 or S=1 two--hole states at low energies leading to very different quasiparticle band structures. We propose that trends upon doping in spin excitational spectrum and quasiparticle density of state can be a way to probe Ni 3d8 configuration.

description: The interaction between a supernova ejecta and the circum-stellar medium drives a strong shock wave which accelerates particles (i.e., electrons and protons). The radio and X-ray emission observed after the supernova explosion constitutes the evidence of the electron acceleration. The accelerated protons are expected to produce GeV-TeV gamma-ray emission via $pp$ collisions, but the flux is usually low since only a small fraction of the supernova kinetic energy is converted into the shock energy at the very early time. The low gamma-ray flux of the nearest supernova explosion, SN 1987A, agrees with this picture. Here we report a serendipitous discovery of a fading GeV gamma-ray source in spatial coincidence with the second nearest supernova--SN 2004dj from our gamma-ray survey of nearby star-forming galaxies with Fermi-LAT. The total gamma-ray energy released by SN 2004dj is about $6\times10^{47}{\rm erg}$. We interpret this gamma-ray emission arising from the supernova ejecta interacting with a surrounding high-density shell, which decelerates the ejecta and converts ~1% of the ejecta's kinetic energy to relativistic protons. In addition, our gamma-ray survey of nearby star-forming galaxies discovers GeV emissions from two star-forming galaxies, i.e., Arp 299 and M33, for the first time.

description: The zero temperature phase diagram of spin glasses on finite connectivity graphs is investigated, with or without magnetic field and/or ferromagnetic bias, for mean field (using the cavity method) and Edwards-Anderson (using numerical ground states computations) models. In the mean field case we show that the phase diagram is complex and compute the equivalent of the zero temperature de Almeida-Thouless line. In the 3d model however, we found a trivial phase diagram. This paper present new analytical results as well as a rapid review of numerical works on ground states.

description: Immune cells coordinate their efforts for the correct and efficient functioning of the immune system (IS). Each cell type plays a distinct role and communicates with other cell types through mediators such as cytokines, chemokines and hormones, among others, that are crucial for the functioning of the IS and its fine tuning. Nevertheless, a quantitative analysis of the topological properties of an immunological network involving this complex interchange of mediators among immune cells is still lacking. Here we present a method for quantifying the relevance of different mediators in the immune network, which exploits a definition of centrality based on the concept of efficient communication. The analysis, applied to the human immune system, indicates that its mediators significantly differ in their network relevance. We found that cytokines involved in innate immunity and inflammation and some hormones rank highest in the network, revealing that the most prominent mediators of the IS are molecules involved in these ancestral types of defence mechanisms highly integrated with the adaptive immune response, and at the interplay among the nervous, the endocrine and the immune systems.

description: We demonstrated the existence of a group algebraic structure hidden in relational knowledge embedding problems, which suggests that a group-based embedding framework is essential for designing embedding models. Our theoretical analysis explores merely the intrinsic property of the embedding problem itself hence is model-independent. Motivated by the theoretical analysis, we have proposed a group theory-based knowledge graph embedding framework, in which relations are embedded as group elements, and entities are represented by vectors in group action spaces. We provide a generic recipe to construct embedding models associated with two instantiating examples: SO3E and SU2E, both of which apply a continuous non-Abelian group as the relation embedding. Empirical experiments using these two exampling models have shown state-of-the-art results on benchmark datasets.

Molecular systematic studies in commelinid monocots
Creators: name: Saarela, Jeffery Michael
Publisher: name: University of British Columbia
Year: 2011

description: To clarify phylogenetic relationships among the major commelinid monocot lineages, among families in the orders Commelinales and Poales, and among grass subfamilies (Poaceae), I surveyed multiple plastid protein-coding regions and associated noncoding regions from exemplar taxa sampled broadly across these lineages. I also characterized phylogenetic relationships in the grass genus Bromus, using two plastid regions and a nuclear region. In commelinids, phylogenetic inferences using parsimony and likelihood are generally congruent, and my analyses provide strong support for many aspects of commelinid relationships. Commelinales and Zingiberales are sister taxa, but the positions of Arecales and Dasypogonaceae are not clear. Commelinales includes a Commelinaceae-Hanguanaceae clade and a (Philydraceae, (Haemodoraceae-Pontederiaceae)) clade. Philydrella is the sister group of the rest of Philydraceae. Poales includes a cyperid clade (Thurniaceae, . (Cyperaceae-Juncaceae)), and a 'core Poales' clade consisting of a graminid clade (Flagellariaceae, (Joinvilleaceae, (Ecdeiocoleaceae-Poaceae))) and a restiid clade (Anarthriaceae, (Centrolepidaceae-Restionaceae)). Ecdeiocoleaceae are moderately supported as the sister group of Poaceae in analyses in which taxon.sampling is most dense. The position of the aquatic Mayacaceae differs between parsimony and likelihood analyses, perhaps reflecting a long-branch artifact. Rapateaceae are part of a clade that includes all Poales except Bromeliaceae and Typhaceae, and the positions of these latter two families at the base of the Poales subtree are unresolved. Within Poaceae, Anomochlooideae and the BEP clade are supported strongly, Anomochlooideae, Pharoideae, and Puelioideae are the successive sister groups (respectively) of the remaining grasses, and Bambusoideae and Pooideae are sister taxa. A generally accelerated substitution rate in Poaceae plastid genomes is shared with most, but not all, Poales lineages. Independent analyses of plastid and nuclear ribosomal data in Bromus indicate that several traditionally recognized sections are monophyletic, but sect. Bromopsis is not. There is some evidence of incongruence between plastid and nuclear linkage groups in Bromus, particularly with respect to relationships among major lineages. Based on plastid data, the dwarf aquatic family Hydatellaceae are not commelinids or (more broadly) monocots, but the sister group of water lilies (Nymphaeales), a result corroborated by nuclear data and morphology.

Bayesian mechanics of perceptual inference and motor control in the brain

description: The free energy principle (FEP) in the neurosciences stipulates that all viable agents induce and minimize informational free energy in the brain to fit their environmental niche. In this study, we continue our effort to make the FEP a more physically principled formalism by implementing free energy minimization based on the principle of least action. We build a Bayesian mechanics (BM) by casting the formulation reported in the earlier publication (Kim 2018) to considering active inference beyond passive perception. The BM is a neural implementation of variational Bayes under the FEP in continuous time. The resulting BM is provided as an effective Hamilton's equation of motion and subject to the control signal arising from the brain's prediction errors at the proprioceptive level. To demonstrate the utility of our approach, we adopt a simple agent-based model and present a concrete numerical illustration of the brain performing recognition dynamics by integrating BM in neural phase space. Furthermore, we recapitulate the major theoretical architectures in the FEP by comparing our approach with the common state-space formulations.

Detailed analysis of the gluonic excitation in the three-quark system in lattice QCD

description: We study the excited-state potential and the gluonic excitation in the static three-quark (3Q) system using SU(3) lattice QCD with $16^3\times 32$ at $β$=5.8 and 6.0 at the quenched level. For about 100 different patterns of spatially-fixed 3Q systems, we accurately extract the excited-state potential $V_{\rm 3Q}^{\rm e.s.}$ together with the ground-state potential $V_{\rm 3Q}^{\rm g.s.}$ by diagonalizing the QCD Hamiltonian in the presence of three quarks. The gluonic excitation energy $ΔE_{\rm 3Q} \equiv V_{\rm 3Q}^{\rm e.s.}-V_{\rm 3Q}^{\rm g.s.}$ is found to be about 1 GeV at the typical hadronic scale. This large gluonic-excitation energy is conjectured to give a physical reason of the success of the quark model for low-lying hadrons even without explicit gluonic modes. We investigate the functional form of $ΔE_{\rm 3Q}$ in terms of the 3Q location. The lattice data of $ΔE_{\rm 3Q}$ are relatively well reproduced by the ``inverse Mercedes Ansatz'' with the ``modified Y-type flux-tube length'', which indicates that the gluonic-excitation mode is realized as a complicated bulk excitation of the whole 3Q system.

description: The apparent difficulty in recovering classical nonlinear dynamics and chaos from standard quantum mechanics has been the subject of a great deal of interest over the last twenty years. For open quantum systems - those coupled to a dissipative environment and/or a measurement device - it has been demonstrated that chaotic-like behaviour can be recovered in the appropriate classical limit. In this paper, we investigate the entanglement generated between two nonlinear oscillators, coupled to each other and to their environment. Entanglement - the inability to factorise coupled quantum systems into their constituent parts - is one of the defining features of quantum mechanics. Indeed, it underpins many of the recent developments in quantum technologies. Here we show that the entanglement characteristics of two `classical' states (chaotic and periodic solutions) differ significantly in the classical limit. In particular, we show that significant levels of entanglement are preserved only in the chaotic-like solutions.
