description: Building on UTIG’s 20 years of experience with fixed-wing aerogeophysical operations, UTIG and KOPRI have collaborated to migrate the UTIG DC-3T instrument suite to two AS-350 helicopters. UTIG’s typical instrument suite consists of a VHF ice-penetrating radar, a laser altimeter, camera, magnetometer, and gravimeter, along with a number of GPS units and an Inertial Navigation System (INS) for accurate positioning. This platform migration required miniaturizing many of the acquisition electronics, designing entirely new antennas for the radar system, as well as substantial software customizations. UTIG and KOPRI first collaborated during the 2015-2016 season to test helicopter gravimetry, a project that represented the first ever deployment of a gravimeter from an icebreaker in Antarctica. The 2016-207 season marks the first time a UTIG-designed VHF radar sounder has been flown on a helicopter. Compared to fixed-wing, the helicopters offer a particularly versatile platform for aerogeophysical survey due to the much lower infrastructure requirements, the ability to operate from an icebreaker, and the technical possibilities afforded by using a more maneuverable platform.

description: We calculate the full density response function, and from it the long-wavelength acoustic dispersion for a two-dimensional system of strongly coupled point dipoles interacting through a 1/r^3 potential at arbitrary degeneracy. Such a system has no RPA limit and the calculation has to include correlations from the outset. We follow the Quasi-Localized Charge (QLC) approach, accompanied by Molecular Dynamics (MD) simulations. Similarly to what has been recently reported for the closely spaced classical electron-hole bilayer [G. J. Kalman et al. Phys. Rev. Lett. 98, 236801 (2007)] and in marked contrast to the RPA, we report a long-wavelength acoustic phase velocity that is wholly maintained by particle correlations and varies linearly with the dipole moment p. The oscillation frequency, calculated both in an extended QLC approximation and in the Singwi-Tosi-Land-Sjolander approximation, is invariant in form over the entire classical to quantum domains all the way down to zero temperature. Based on our classical MD-generated pair distribution function data and on ground-state energy data generated by recent quantum Monte Carlo simulations on a bosonic dipole system [Astrakharchik et al, Phys. Rev. Lett. 98, 060405 (2007)], there is a good agreement between the QLCA kinetic sound speeds and the standard thermodynamic sound speeds in both the classical and quantum domains.

description: Bone morphogenetic proteins (BMPs) are members of the transforming growth factor-beta (TGFβ) superfamily of cytokines. While some ligand members are potent inducers of angiogenesis, others promote vascular homeostasis. However, the precise understanding of the molecular mechanisms underlying these functions is still a growing research field. In bone, the tissue in which BMPs were first discovered, crosstalk of TGFβ/BMP signaling with mechanobiology is well understood. Likewise, the endothelium represents a tissue that is constantly exposed to multiple mechanical triggers, such as wall shear stress, elicited by blood flow or strain, and tension from the surrounding cells and to the extracellular matrix. To integrate mechanical stimuli, the cytoskeleton plays a pivotal role in the transduction of these forces in endothelial cells. Importantly, mechanical forces integrate on several levels of the TGFβ/BMP pathway, such as receptors and SMADs, but also global cell-architecture and nuclear chromatin re-organization. Here, we summarize the current literature on crosstalk mechanisms between biochemical cues elicited by TGFβ/BMP growth factors and mechanical cues, as shear stress or matrix stiffness that collectively orchestrate endothelial function. We focus on the different subcellular compartments in which the forces are sensed and integrated into the TGFβ/BMP growth factor signaling.
Using polarized maser to detect high-frequency relic gravitational waves

description: A GHz maser beam with Gaussian-type distribution passing through a homogenous static magnetic field can be used to detect gravitational waves (GWs) with the same frequency. The presence of GWs will perturb the electromagnetic (EM) fields, giving rise to perturbed photon fluxes (PPFs). After being reflected by a fractal membrane, the perturbed photons suffer little decay and can be measured by a microwave receiver. This idea has been explored to certain extent as a method for very high frequency gravitational waves. In this paper, we examine and develop this method more extensively, and confront the possible detection with the predicted signal of relic gravitational waves (RGWs). A maser beam with high linear polarization is used to reduce the background photon fluxes (BPFs) in the detecting direction as the main noise. As a key factor of applicability of this method, we give a preliminary estimation of the sensitivity of a sample detector limited by thermal noise using currently common technology. The minimal detectable amplitude of GWs is found to be $h_{\rm{min}}\sim10^{-30}$. Comparing with the known spectrum of the RGWs in the accelerating universe for $β=-1.9$, there is still roughly a gap of $4\sim 5$ orders. However, possible improvements on the detector can further narrow down the gap and make it a feasible method to detect high frequency RGWs.

description: Humans build 3D understandings of the world through active object exploration, using jointly their senses of vision and touch. However, in 3D shape reconstruction, most recent progress has relied on static datasets of limited sensory data such as RGB images, depth maps or haptic readings, leaving the active exploration of the shape largely unexplored. Inactive touch sensing for 3D reconstruction, the goal is to actively select the tactile readings that maximize the improvement in shape reconstruction accuracy. However, the development of deep learning-based active touch models is largely limited by the lack of frameworks for shape exploration. In this paper, we focus on this problem and introduce a system composed of: 1) a haptic simulator leveraging high spatial resolution vision-based tactile sensors for active touching of 3D objects; 2)a mesh-based 3D shape reconstruction model that relies on tactile or visuotactile signals; and 3) a set of data-driven solutions with either tactile or visuotactile priors to guide the shape exploration. Our framework enables the development of the first fully data-driven solutions to active touch on top of learned models for object understanding. Our experiments show the benefits of such solutions in the task of 3D shape understanding where our models consistently outperform natural baselines. We provide our framework as a tool to foster future research in this direction.

description: A cranking harmonic oscillator model, widely used for the physics of fast rotating nuclei and Bose-Einstein condensates, is re-investigated in the context of PT-symmetry. The instability points of the model are identified as exceptional points. It is argued that - even though the Hamiltonian appears hermitian at first glance - it actually is not hermitian within the region of instability.

description: We present an XMM-Newton observation of the long-overlooked radio source G350.1-0.3. The X-ray spectrum of G350.1-0.3 can be fit by a shocked plasma with two components: a high-temperature (1.5 keV) region with a low ionization time scale and enhanced abundances, plus a cooler (0.36 keV) component in ionization equilibrium and with solar abundances. The X-ray spectrum and the presence of non-thermal, polarized, radio emission together demonstrate that G350.1-0.3 is a young, luminous supernova remnant (SNR), for which archival HI and 12-CO data indicate a distance of 4.5 kpc. The diameter of the source then implies an age of only ~900 years. The SNR's distorted appearance, small size and the presence of 12-CO emission along the SNR's eastern edge all indicate that the source is interacting with a complicated distribution of dense ambient material. An unresolved X-ray source, XMMU J172054.5-372652, is detected a few arcminutes west of the brightest SNR emission. The thermal X-ray spectrum and lack of any multi-wavelength counterpart suggest that this source is a neutron star associated with G350.1-0.3, most likely a "central compact object", as seen coincident with other young SNRs such as Cassiopeia A.

description: Appropriate medical care for donkeys is challenging despite being important working animals in non-industrialized countries and pets in first world countries. Although the same principles of diagnosis and therapy as in horses are commonly applied, there are differences in reference values and physiologic reaction to dynamic tests. However, donkeys seem to suffer from typical equine diseases, such as metabolic syndrome and pituitary pars intermedia dysfunction (PPID). Asinine metabolic syndrome (AMS) comprises obesity, insulin dysregulation, and laminitis. The principles of diagnosis are similar to horses. Donkey-specific reference ranges for insulin and glucose have been evaluated previously. Examinations regarding dynamic testing revealed differences in the intravenous glucose tolerance test and the combined insulin tolerance test compared to horses. The therapy of AMS is based mainly on weight loss and exercise. There are conflicting data regarding the incidence of PPID in donkeys. Laminitis and hypertrichosis were described as the main clinical signs. Species-specific and seasonal reference ranges were defined to diagnose PPID in donkeys. Furthermore, the dexamethasone suppression test, the thyrotropin releasing hormone (TRH) test and the combined dexamethasone suppression/TRH test were evaluated. Pergolide is commonly recommended for treatment.
Employer-sponsored training : an analysis of the British Columbia electronics industry

description: Training and human resource development sponsored by the private sector has become increasingly important and topical in North America. Yet, the attention devoted to it by policymakers, academe and industry itself has not risen accordingly. Government and industry are faced with the challenge of formulating effective public and private policy to facilitate the qualitative and quantitative development of employer-sponsored training. There is a paucity of information on employer-sponsored training. Therefore, the intent of this study was to determine the nature and extent and qualitative issues of the phenomenon in one industry: the British Columbia electronics industry. The literature on employer-sponsored training was reviewed from three perspectives. First, the theoretical, historical and conceptual roots of the topic were presented. Second, the quantitative data on employer-sponsored training in North America was summarized. Third, an overview of the most pressing qualitative issues related to the subject was presented. As a result of this process, five main research questions were derived relating to the following aspects of the B. C. electronics industry: human resource requirements; sources of human resources; nature and extent of training; training decision-making; and public policy. A 15-page open-ended and closed questionnaire was developed and sent to 80 electronics companies in British Columbia. Forty-eight or 60% of the companies responded to the survey. The responses to individual questions yielded several interesting patterns in the data. The small sample size and the nominal nature of the data collected prevented any extensive statistical analysis of the results to test for relationships between variables. The chi-square test for independence was utilized and identified a few plausible relationships between key variables. A list of specific conclusions derived from the results painted an overall picture of the training and human resource activity in the British Columbia electronics industry. The limitations of the study and its implications for future research and public policy were outlined.

description: The water crisis can alternatively be called a governance crisis. Thus, the demand for good water governance to ensure effective water resources management and to attain specific water goals is growing. Many countries subscribe to the Integrated Water Resources Management (IWRM) approach to achieve this goal. The Integrated Water Resources Management approach aims to ensure a process that promotes the coordinated development and management of water, land, and related resources in a drainage basin to maximise economic and social welfare equitably without compromising the sustainability of vital ecosystems. The design of the Integrated Water Resources Management approach, including its pillars and principles, aspires to good water governance and effective resource management. However, empirical studies examining this hypothesis and analysing the impact of the Integrated Water Resources Management approach on water resources governance are limited, especially in developing countries. Therefore, we characterised and compared the water resources governance aspects of two catchments in Uganda’s Lake Albert basin. One of the catchments was exposed to integrated water resources management projects, while the other had no exposure to integrated water resources management projects. Some of the factors that supported the comparability of the two sites included spatial proximity linking into a related hydrological and social-economic setup, common water needs and belonging to the same water administration zone. Comparing both areas led us to analyse whether there was a difference in water resources governance actions, as well as in the quality of water resources governance, under the same overall water management and administrative zone. The data were based on field surveys using questionnaires and information guides in both catchments. The results show that the performance of water resources governance is markedly better in the catchment with Integrated Water Resources Management practices than the base catchment unaffected by these practices. Key themes examined include water resources governance styles, water resources governance systems presence, functionality, the performance of good governance principles, and water resources management effectiveness. The findings contribute to the aspirations for the promotion of integrated water management approaches for improved water resources governance, and the concept that the effectiveness of water resources management measures depends on governance effectiveness. Water governance is significant, as it spells out the power, rights, decisions, and priorities relating to given water resources and communities.

description: Well-tempering is a promising classical method of dynamically screening an arbitrarily large vacuum energy and generating a late-time, low energy de Sitter vacuum state. In this paper, we study for the first time self-tuning in teleparallel gravity and obtain well-tempered cosmological models in the teleparallel gravity analogue of Horndeski theory. This broadens the scope of well-tempered cosmology and teases the potentially far richer cosmological dynamics that could be anchored on teleperallel gravity. We expand the well-tempered recipe to its most general form so far and use it to search for the first well-tempered cosmologies in teleparallel gravity. We also study the cosmological dynamics in a well-tempered model and demonstrate the dynamical stability of the vacuum, the compatibility with a matter era, and the stability of the vacuum through a phase transition.

description: The retrieval of sun-induced chlorophyll fluorescence is greatly beneficial to studies of marine phytoplankton biomass, physiology, and composition, and is required for user applications and services. Customarily phytoplankton chlorophyll fluorescence is determined from satellite measurements through a fluorescence line-height algorithm using three bands around 680 nm. We propose here a modified retrieval, making use of all available bands in the relevant wavelength range, with the goal to improve the effectiveness of the algorithm in optically complex waters. For the Ocean and Land Colour Instrument (OLCI), we quantify a Fluorescence Peak Height by fitting a Gaussian function and related terms to the top-of-atmosphere reflectance bands between 650 and 750 nm. This algorithm retrieves, what we call Fluorescence Peak Height by fitting a Gaussian function upon other terms to top-of-atmosphere reflectance bands between 650 and 750 nm. This approach is applicable to Level-1 and Level-2 data. We find a good correlation of the retrieved fluorescence product to global in-situ chlorophyll measurements, as well as a consistent relation between chlorophyll concentration and fluorescence from radiative transfer modelling and OLCI/in-situ comparison. Evidence suggests, the algorithm is applicable to complex waters without needing an atmospheric correction and vicarious calibration, and features an inherent correction of small spectral shifts, as required for OLCI measurements.

Field-free evolution of this rotational wavepacket has been mapped to high temporal resolution by a time-delayed pulse, initiating rapid double ionization, which is highly sensitive to the angle of orientation of the molecular axis with respect to the polarization direction, $θ$. The detailed fractional revivals of the neutral D$_2$ wavepacket as a function of $θ$ and evolution time have been observed and modelled theoretically.

description: Distinct pathogenic and epidemiological features underlie different Theileria parva strains resulting in different clinical manifestations of East Coast Fever and Corridor Disease in susceptible cattle. Unclear delineation of these strains limits the control of these diseases in endemic areas. Hence, an accurate characterization of strains can improve the treatment and prevention approaches as well as investigate their origin. Here, we describe a set of single nucleotide polymorphisms (SNPs) based on 13 near-complete mitogenomes of T. parva strains originating from East and Southern Africa, including the live vaccine stock strains. We identified 11 SNPs that are non-preferentially distributed within the coding and non-coding regions, all of which are synonymous except for two within the cytochrome b gene of buffalo-derived strains. Our analysis ascertains haplotype-specific mutations that segregate the different vaccine and the buffalo-derived strains except T. parva-Muguga and Serengeti-transformed strains suggesting a shared lineage between the latter two vaccine strains. Phylogenetic analyses including the mitogenomes of other Theileria species: T. annulata, T. taurotragi, and T. lestoquardi, with the latter two sequenced in this study for the first time, were congruent with nuclear-encoded genes. Importantly, we describe seven T. parva haplotypes characterized by synonymous SNPs and parsimony-informative characters with the other three transforming species mitogenomes. We anticipate that tracking T. parva mitochondrial haplotypes from this study will provide insight into the parasite’s epidemiological dynamics and underpin current control efforts.
Hysteresis in Two Dimensional Arrays of Magnetic Nanoparticles

Subjects: subject: Materials Science (cond-mat.mtrl-sci)

description: We perform computer simulations to probe the magnetic hysteresis in a two-dimensional ($L^{}_x\times L^{}_y$) assembly of magnetic nanoparticles as a function of dipolar interaction strength $h^{}_d$, temperature $T$, aspect ratio $A^{}_r=L^{}_y/L^{}_x$, and the applied alternating magnetic field's direction. In the absence of magnetic interaction ($h^{}_d\approx0$) and thermal fluctuations ($T=0$ K), the hysteresis follows the Stoner and Wohlfarth model, as expected. For weak dipolar interaction and substantial temperature, the hysteresis has the dominance of superparamagnetic behaviour, irrespective of the applied magnetic field's direction and $A^{}_r$. Interestingly, the hysteresis curve has all the characteristics of antiferromagnetic interaction dominance for $A^{}_r\leq6$ and considerable dipolar interaction strength ($h^{}_d>0.2)$, which is independent of applied magnetic direction. When the magnetic field is applied along the system's shorter axis ($x$-direction), a non-hysteresis straight line is observed with large $h^{}_d$. In the case of the magnetic field applied along the long axis of the sample ($y$-direction), ferromagnetic interaction dominates the hysteresis for large $h^{}_d$ and $A^{}_r>6$. Irrespective of $h^{}_d$ and applied magnetic field's direction, the coercive field $μ^{}_oH^{}_c$ and remanence $M^{}_r$ are minimal for $A^{}_r\leq6$ and significant temperature. They are found to increase with $h^{}_d$ when $A^{}_r$ is enormous. Remarkably, the variation of hysteresis loop area $E^{}_H$ as a function of these parameters is the same as that of the coercive field variation. We believe that the concepts presented in this work are relevant in various technological applications such as spintronics and magnetic hyperthermia, in which such self-assembled nanoparticle arrays are ubiquitous.

description: We propose a general quantum theory of optical phase and instantaneous frequency in the time domain for slowly varying optical signals. Guided by classical estimation theory, we design homodyne phase-locked loops that enable quantum-limited measurements of temporal phase and instantaneous frequency. Standard and Heisenberg quantum limits to such measurements are then derived. For optical sensing applications, we propose multipass and Fabry-Pérot position and velocity sensors that take advantage of the signal-to-noise-ratio enhancement effect of wideband angle modulation without requiring nonclassical light. We also generalize our theory to three spatial dimensions for nonrelativistic bosons and define an Hermitian fluid velocity operator, which provides a theoretical underpinning to the current-algebra approach of quantum hydrodynamics.

Development of a knowledge about aging scale
Creators: name: Gallie, Karen Ann
Publisher: name: University of British Columbia
Year: 2010

description: The purpose of this study was to develop a reliable and valid knowledge about aging scale. Two hundred and ninety-eight subjects (128 males, 170 females) from the University of British Columbia, Simon Fraser University, and members of the general population, ranging from 17 to 65 years of age, and having 0 to 12 years of post secondary education, participated in this study. Subjects were chosen on the basis of having gerontological, versus no gerontological training. Subjects responded to computer randomized Likert scale questionnaires consisting of the initial 60 item Proto Knowledge About Aging Scale, Palmore's Facts on Aging Quiz (FAQ), and Kogan's Old People Scale (OP). Responses to the initial Proto scale were used to construct a psychometrically appropriate 40 item scale that consisted of three factor dimensions interpreted as Psychological, Biological Change, and Social Lifestyle/Histological Change. This 40 item scale had a Chronbach's alpha of 0.839 and a construct validity value of 0.701. Analysis of Covariance results indicated that the independent variables of age, gender, and years of post secondary education, had no significant extraneous confounding influence (p≤ 0.05) on Proto scale results. However, type of training did influence Proto scale results, with those subjects having gerontological training scoring significantly higher (Duncan's Multiple Range Test p≤ 0.05) than those with no gerontological training. Investigation into Proto's scale characteristics were further analyzed in relation to the subjects in this investigation, Palmore's FAQ, and Kogan's OP scale, with discussion focussing on Proto's psychometric rigor as compared to Palmore's FAQ.

description: We address the old and widely debated question of the statistical properties of integrable quantum systems, through the analysis of the paradigmatic Lieb-Liniger model. This quantum many-body model of 1-d interacting bosons allows for the rigorous determination of energy spectra via the Bethe ansatz approach and our interest is understanding whether Poisson statistics is a characteristic feature of this model. Using both analytical and numerical studies we show that the properties of spectra strongly depend on whether the analysis is done for a full energy spectrum or for a single subset with fixed total momentum. We show that the Poisson distribution of spacing between nearest-neighbor energies can occur only for a set of energy levels with fixed total momentum, for neither too large nor too weak interaction strength, and for sufficiently high energy. On the other hand, when studying long-range correlations between energy levels, we found strong deviations from the predictions given by a Poisson process.

description: To explicitly account for asymptotic dependence between rainfall intensity maxima of different accumulation duration, a recent development for estimating Intensity-Duration-Frequency (IDF) curves involves the use of a max-stable process. In our study, we aimed to estimate the impact on the performance of the return levels resulting from an IDF model that accounts for such asymptotical dependence. To investigate this impact, we compared the performance of the return level estimates of two IDF models using the quantile skill index (QSI). One IDF model is based on a max-stable process assuming asymptotic dependence; the other is a simplified (or reduced) duration-dependent GEV model assuming asymptotic independence. The resulting QSI shows that the overall performance of the two models is very similar, with the max-stable model slightly outperforming the other model for short durations (d≤10h). From a simulation study, we conclude that max-stable processes are worth considering for IDF curve estimation when focusing on short durations if the model’s asymptotic dependence can be assumed to be properly captured.

description: We have investigated the half-filling two-orbital Hubbard model on a triangular lattice by means of the dynamical mean-field theory (DMFT). The densities of states and optical conductivity clearly show the occurence of metal-insulating transition (MIT) at U$_{c}$, U$_{c}$=18.2, 16.8, 6.12 and 5.85 for J=0, 0.01U, U/4 and U/3, respectively. The distinct continuities of double occupation of electrons, local square moments and local susceptibility of the charge, the spin and the orbital at J > 0 suggest that the MIT is the first-order; however at J=0, the MIT is the second-order in the half-filling two-orbital Hubbard model on triangular lattices. We attribute the first-order nature of the MIT to the low symmetry of the systems with finite Hund's coupling J.

description: We present parsec-scale kinematics of eleven nearby galactic nuclei, derived from adaptive-optics assisted integral-field spectroscopy at (near-infrared) CO band-head wavelengths. We focus our analysis on the balance between ordered rotation and random motions, which can provide insights into the dominant formation mechanism of nuclear star clusters (NSCs). We divide our target sample into late- and early-type galaxies, and discuss the nuclear kinematics of the two sub-samples, aiming at probing any link between NSC formation and host galaxy evolution. The results suggest that the dominant formation mechanism of NSCs is indeed affected by the different evolutionary paths of their hosts across the Hubble sequence. More specifically, nuclear regions in late-type galaxies are on average more rotation dominated, and the formation of nuclear stellar structures is potentially linked to the presence of gas funnelled to the center. Early-type galaxies, in contrast, tend to display slower-rotating NSCs with lower ellipticity. However, some exceptions suggest that in specific cases, early-type hosts can form NSCs in a way similar to spirals.

description: Several users of our AS relationship inference data (http://www.caida.org/data/active/as-relationships/), released with cs/0604017, asked us why it contained AS relationship cycles, e.g., cases where AS A is a provider of AS B, B is a provider of C, and C is a provider of A, or other cycle types. Having been answering these questions in private communications, we have eventually decided to write down our answers here for future reference.

Exploring self-based consumer behaviour approaches to understanding demand reduction for rhino horn and ivory
Creators: name: Sharif, Vian Dhia

description: Within our lifetimes, iconic species that walked the earth for some 50 million years - elephant and rhino, for example - could vanish. Why? In making sense of the mystery that finds buyers paying inflated prices of some $97,000 per kilo for some wildlife commodities that are without obvious utility, governments, NGOs and law enforcement agencies recognise that demand for illegal wildlife products must be better understood if the trade is to end. An influential premise cited by Belk (1988) and developed in the consumer marketing literature is that “we cannot hope to understand consumer behaviour without first gaining some understanding of the meanings that consumers attach to possessions. That we are what we have is perhaps the most basic and powerful fact of consumer behaviour.” (1988, p.139). Despite this foundational principle, research informed by this concept has not been widely applied to understanding consumer decision-making for illegal wildlife products. To address this, the present research is one of the first to test dimensions conferred upon two illegal wildlife products using theory based on this evidence with the aim of understanding the drivers behind consumers’ buying decisions. In three studies, I demonstrate that it is possible to fill a gap in the literature by applying self-based customer brand frameworks to explore consumer relationships to high profile illegal wildlife products. Findings show that while attributes conferred by consumers on rhino horn and ivory may be aligned to positive self-actualisation through the bestowing of status and affluence, inconsistencies in brand image and with moral values discourage self-relevance. The effect of the latter implies that purchase behaviour would be negatively impacted. The research highlights the role of self-relevance and awareness campaigns in driving consumer intentions to adopt new behaviours and reverse environmentally deleterious consumption decisions, whilst providing insights for both research and practice.

description: Theoretical analysis is given for a two-photon subtraction from a continuous wave (CW) squeezed vacuum with finite time separation between two detection events. In the CW photon subtraction process, the generated states are inevitably described by temporal mutimode states. Our approach is based on Schrödinger picture which provides mathematically simple forms and an intuitive understanding of its multimode structure. We show that, in our process, the photon subtracted squeezed vacuum is generated in two temporal modes and one of these modes acts as an ancillary mode to make the other one a large amplitude coherent state superposition.

description: The physical origin of the so-called chirality-induced spin selectivity (CISS) effect has puzzled experimental and theoretical researchers over the past few years. Early experiments were interpreted in terms of unconventional spin-orbit interactions mediated by the helical geometry. However, more recent experimental studies have clearly revealed that electronic exchange interactions also play a key role in the magnetic response of chiral molecules in singlet states. In this investigation, we use spin-polarized closed shell density functional theory calculations to address the influence of exchange contributions to the interaction between helical molecules as well as of helical molecules with magnetized substrates. We show that exchange effects result in differences in the interaction properties with magnetized surfaces, shedding light into the possible origin of two recent important experimental results: enantiomer separation and magnetic exchange force microscopy with AFM tips functionalized with helical peptides.
Development of a framework for analyzing nonformal education systems
Creators: name: Mumba, Elizabeth Cisece
Publisher: name: University of British Columbia
Year: 2010

description: This study analyzes the concept of nonformal education and provides a framework for analyzing nonformal education systems. Nonformal education is seen by policy makers and funding agencies as one of the alternatives to formal schooling that may assist developing countries in the modernization process. Nonformal education is defined as any systematic learning that is provided outside the formal system to meet the learning needs of adults as well as children. In order to achieve the objectives of the study, two separate literature reviews are provided. Firstly, a review of the literature on the concept of nonformal education is provided. The review analyzes how the concept of nonformal education has developed. It discusses some issues regarding definitional problems; major characteristics of nonformal education and the major differences between nonformal education and formal education. Various theories that relate to nonformal education and development are discussed. Following the conceptual analysis, a review of selected research that has been conducted on nonformal education in the last twelve years is provided. Only major cross-cultural studies are reviewed as they provide a basis for comparison. Conclusions of the studies are discussed. A framework is provided for analyzing and comparing nonformal education systems. The framework identifies three levels of analysis: national, regional, and local. The major elements of the framework are discussed and questions are provided indicating at which level they can be asked. Major conclusions of the study are discussed in terms of planning nonformal education systems. Some recommendations for further research are provided.
