title: Making A Difference : Ways Of Teaching And Learning In General National Qualifications
Creators: name: Moore, Patricia Anne
Publisher: name: The Open University
Year: 2001

description: There is growing evidence of the positive affects of General National Vocational Qualifications on students and widely held views, almost assumptions, on appropriate teaching and learning styles. As these are not explicit in any form of the specifications it is postulated that it is the mediating influence of teachers which will determine the extent to which GNVQs are student-centred in learning and assessment, and how successful any course is in terms of levels of achievement by students. By following multiple lines of evidence in three advanced courses in one institution a comprehensive and robust picture is built up which illustrates the journey through a course of study for students and their teachers. Diverse aspects of the teaching and learning process drawn from differing perspectives, a variety of research reports of GNVQ courses, and the relationship of the significant role of formative and summative assessment in motivation and learning were considered in the literature review. The strands in the research methodology were also drawn together from lines of pursuit suggested by the literature. Data were gathered through student questionnaires, interviews with teachers and students, classroom observations and the scrutiny of students' work, assignments and various other documents. A synthesis of several seemingly disparate theoretical models of teaching and learning is provided leading to a conclusion that there is a much richer and more subtle range of activities occurring in student-centred teaching and learning than is readily explained by any one model. There is persuasive evidence emerging in a small context of current practice in Advanced GNVQ teaching that has resonance with wider studies of effective teaching. This has implications in contemplating the changes in post-16 education consequent upon the introduction of Curriculum 2000, both at institutional level and perhaps nationally.

description: We present a dispersive analysis with the aim to extract the $Υ$-p scattering length from $γp \to Υp$ experiments. In this framework, the imaginary part of the $Υ$-p forward scattering amplitude is obtained from $γp \to Υp$ cross section measurements, and is constrained at high energies from existing HERA and LHC data. Its real part is calculated through a once-subtracted dispersion relation, and the subtraction constant is proportional to the $Υ$-p scattering length. We perform a feasibility study for $Υ$ photo-production experiments at an Electron-Ion Collider and discuss the sensitivity and precision that can be reached in the extraction of the $Υ$-p scattering length.

description: UW CrB (MS1603+2600) is a peculiar short period X-ray binary that exhibits extraordinary optical behaviour. The optical light curve shape of the system changes drastically from night to night, without any changes in overall brightness. Here we report X-ray observations of UW CrB obtained with {\it XMM-Newton}. We find evidence for several X-ray bursts confirming a neutron star primary. This considerably strengthens the case that UW CrB is an Accretion Disc Corona (ADC) system located at a distance of at least 5--7 kpc, (3--5 kpc above the galactic plane). The X-ray and optical monitor (UV+optical) light curves show remarkable shape variation from one observing run to another, which we suggest are due to large scale variations in the accretion disc shape resulting from a warp which periodically obscures the optical and soft X-ray emission. This is also supported by the changes in phase-resolved X-ray spectra.

description: We use effective field theory to compute the influence of nuclear structure on precision calculations of atomic energy levels. As usual, the EFT's effective couplings correspond to the various nuclear properties (such as the charge radius, nuclear polarizabilities, Friar and Zemach moments {\it etc.}) that dominate its low-energy electromagnetic influence on its surroundings. By extending to spinning nuclei the arguments developed for spinless ones in {\tt arXiv:1708.09768}, we use the EFT to show -- to any fixed order in $Zα$ (where $Z$ is the atomic number and $α$ the fine-structure constant) and the ratio of nuclear to atomic size -- that nuclear properties actually contribute to electronic energies through fewer parameters than the number of these effective nuclear couplings naively suggests. Our result is derived using a position-space method for matching effective parameters to nuclear properties in the EFT, that more efficiently exploits the simplicity of the small-nucleus limit in atomic systems. By showing that precision calculations of atomic spectra depend on fewer nuclear uncertainties than naively expected, this observation allows the construction of many nucleus-independent combinations of atomic energy differences whose measurement can be used to test fundamental physics (such as the predictions of QED) because their theoretical uncertainties are not limited by the accuracy of nuclear calculations. We provide several simple examples of such nucleus-free predictions for Hydrogen-like atoms.

Type Ia Supernovae and Cosmology

Publisher: name: arXiv

Subjects: subject: Astrophysics (astro-ph)

description: I discuss the use of Type Ia supernovae (SNe Ia) for cosmological distance determinations. Low-redshift SNe Ia (z < 0.1) demonstrate that the Hubble expansion is linear with H_0 = 72 +/- 8 km/s/Mpc, and that the properties of dust in other galaxies are generally similar to those of dust in the Milky Way. The measured luminosity distances of SNe Ia as a function of redshift have shown that the expansion of the Universe is currently accelerating, probably due to the presence of repulsive dark energy such as Einstein's cosmological constant (Lambda). From about 200 SNe Ia, we find that Omega_Lambda - 1.4 Omega_M = 0.35 +/- 0.14. Combining our data with other results, we find a best fit for Omega_M and Omega_Lambda of 0.28 and 0.72, respectively. A number of possible systematic effects (dust, supernova evolution) thus far do not seem to eliminate the need for Omega_Lambda > 0. Recently, analyses of SNe Ia at z = 1.0-1.7 provide further support for current acceleration, and give tentative evidence for an early epoch of deceleration. The dynamical age of the Universe is estimated to be 13.1 +/- 1.5 Gyr. According to the most recent data sets, the SN Ia rate at z > 1 is several times greater than that at low redshifts, presumably because of higher star formation rates long ago. Moreover, the typical delay time from progenitor star formation to SNIa explosion appears to be substantial, ~3 Gyr. Current projects include the measurement of a few hundred SNe Ia at z = 0.2-0.8 to more accurately determine the equation-of-state parameter of the dark energy, w = P/(ρc^2), whose value is now constrained by SNe Ia to be in the range -1.48 < w < -0.72 at 95% confidence.

description: We consider the problem of tidal disruption of stars in the centre of a galaxy containing a supermassive binary black hole with unequal masses. We assume that over the separation distance between the black holes the gravitational potential is dominated by the more massive black hole. Also, we assume that the number density of stars is concentric with the primary black hole and has a power law cusp.We show that the bulk of stars with a small angular-momentum component normal to the black hole binary orbit can reach a small value of total angular momentum through secular evolution in the gravitational field of the binary, and hence they can be tidally disrupted. This effect is analogous to the so-called Kozai effect (Kozai, 1962, Lidov, 1961,1962) well known in celestial mechanics. We develop an analytical theory of secular evolution of the stellar orbits and calculate the rate of tidal disruption. We confront our analytical theory with a simple numerical model and find very good agreement. Our results show that for primary black-hole mass \sim 10^{6}-10^{7}M_{\odot}, the black- hole mass ratio q > 10^{-2}, cusp size \sim 1pc, the tidal disruption rate can be as large as \sim 10^{-2}-1M_{\odot}/yr. This is at least 10^{2}-10^{4} times larger than estimated for the case of a single supermassive black hole. The duration of the phase of enhanced tidal disruption is determined by the dynamical friction time scale, and it is rather short: \sim 10^{5}yr. The dependence of the tidal disruption rate on the mass ratio, as well as on the size of the cusp, is also discussed.

description: The superiority of deep learning performance is threatened by safety issues for itself. Recent findings have shown that deep learning systems are very weak to adversarial examples, an attack form that was altered by the attacker's intent to deceive the deep learning system. There are many proposed defensive methods to protect deep learning systems against adversarial examples. However, there is still a lack of principal strategies to deceive those defensive methods. Any time a particular countermeasure is proposed, a new powerful adversarial attack will be invented to deceive that countermeasure. In this study, we focus on investigating the ability to create adversarial patterns in search space against defensive methods that use image filters. Experimental results conducted on the ImageNet dataset with image classification tasks showed the correlation between the search space of adversarial perturbation and filters. These findings open a new direction for building stronger offensive methods towards deep learning systems.

description: One of the important directions of the use of renewable energy sources is the production of biogas. This paper presents an assessment of the profitability of sorghum cultivation for biogas depending on the nitrogen fertilization level. Data used in this paper are the results a field experiment from the years 2010-2014 and market quotations. The analysis showed that sorghum is characterized by a high level of yields, but they are variable between years. However, the cultivation of this species for biogas with yields ranging from 58 to 145 t/ha .g.m. is economically effective. In addition, an increase the dose of mineral nitrogen fertilization improves economic efficiency of sorghum cultivation from area unit, used as a raw material for silage

description: We study duality transformation and duality symmetry in the the electromagnetic-like charged p-form theories. It is shown that the dichotomic characterization of duality groups as $Z_2$ or SO(2) remains as the only possibilities but are now present in all dimensions even and odd. This is a property defined in the symplectic sector of the theory both for massive and massless tensors. It is shown that the duality groups depend, in general, both on the ranks of the fields and on the dimension of the spacetime. We search for the physical origin of this two-fold property and show that it is traceable to the dimensional and rank dependence of the parity of certain operator (a generalized-curl) that naturally decomposes the symplectic sector of the action. These operators are only slightly different in the massive and in the massless cases but their physical origin are quite distinct.

The RDP is programmed base on six measures and a number of sub-measures, which are developed to reflect modern trends in the development of rural areas. For Poland there was specified budget of more than 13.5 billion euros, including the EAFRD measures at 8.6 billion (63.7%) and 4.9 billion (36.3%) of the national co-financing. The spending trends of RDP means presented to the European Commission were slightly adjusted, through the launch of additional activities associated with investments in farms located in Natura 2000 areas and in less favoured areas (LFA). Start of financial instruments will be delayed by protracted legislative process.
Speckled speckled speckle

Publisher: name: arXiv
Year: 2020
Subjects: subject: Optics (physics.optics)

description: Speckle is the spatial fluctuation of irradiance seen when coherent light is reflected from a rough surface. It is due to light reflected from the surface's many nooks and crannies accumulating vastly-discrepant time delays, spanning much more than an optical period, en route to an observation point. Although speckle with continuous-wave (cw) illumination is well understood, the emerging interest in non-line-of-sight (NLoS) imaging using coherent light has created the need to understand the higher-order speckle that results from multiple rough-surface reflections, viz., speckled speckle and speckled speckled speckle. Moreover, the recent introduction of phasor-field ($\mathcal{P}$-field) NLoS imaging---which relies on amplitude-modulated coherent illumination---requires pushing beyond cw scenarios for speckle and higher-order speckle. In this paper, we take first steps in addressing the foregoing needs using a three-diffuser transmissive geometry that is a proxy for three-bounce NLoS imaging. In the small-diffusers limit, we show that the irradiance variances of cw and modulated $n$th-order speckle coincide and are $(2^n-1)$-times those of ordinary (first-order) speckle. The more important case for NLoS imaging, however, involves extended diffuse reflectors. For our transmissive geometry with extended diffusers, we treat third-order cw speckle and first-order modulated speckle. Our results there imply that speckle is unlikely to impede successful operation of coherent-illumination cw imagers, and they suggest that the same might be true for $\mathcal{P}$-field imagers.

The life cycle experiences and influences of adoption through Aboriginal adult’s stories
Creators: name: Arsenault, April Ann
Publisher: name: University of British Columbia
Year: 2010

description: This study explored the life cycle experiences and influences of adoption of eight Aboriginal adults (six female and two male). The study was qualitative, used categorical content analysis, life cycle developmental theory, Aboriginal world-view and storytelling. The purposes of the study were to hear the voices of Aboriginal adoptees; to understand how adoption has influenced Aboriginal adoptees lives, and to gain knowledge that can make a difference in the practice of the adoption of Aboriginal children. Interviews were conducted, data was analyzed and the following developmental markers were extracted from the data: growing, discovering, reconnecting and knowing. Themes emerged in each of the markers. The results of this study indicate that how and when the adoption story is told is a very significant experience for an adoptee. Aboriginal culture was very much missing for these storytellers as all were placed in non-Aboriginal homes. For those who choose to search for birth family, they must first go back to a period of which they know little about (birth) before moving forward. Although each participant's story is unique, they also shared experiences such as being told of their adoption, searching and/or reconnecting with their birth families, gaining awareness of their Aboriginal culture, developing personal views on adoption and knowing who they are. Another finding was that their journey was impacted by their experience and that their experience with adoption will be a life long process of healing and resistance. Implications of the study show that culture is a fundamental aspect in a system that aims to work in the best interests of the child. Governments, agencies and Aboriginal communities need to work together to create policy and practices that support Aboriginal adoptees, biological/adoptive families and Aboriginal communities. Systems and policies need to support the creation of more Aboriginal foster and adoptive homes and schools of social work and Aboriginal communities need to support the enrolment of Aboriginal students in pursuing social work. This study illustrates how storytelling, the traditional form of oral history is a powerful and effective method to conduct research with Aboriginal people and with individuals who have experienced colonization.

description: Abstract

Background: Life skills training programs help adolescents make healthy choices that lead to meaningful lives. These skills will enhance the youth's mental health and abilities as they face the real challenges of life. It helps young people analyze and take positive action to protect themselves.  Life skills facilitate the integrated development of individuals to function effectively. Objective: This review aims to determine the impact of the life skills training program on Psychological well-being (anxiety, depression and stress) among adolescents. Study design and methods: The review will be conducted according to PRISMA guidelines. The International Prospective Register for Systematic Reviews has accepted this protocol. Following the three procedures, a literature search will be conducted on research articles published between 2011 and 2021 that are limited to the English language. A preliminary search will be made using terms such as life skills training, anxiety, depression, stress, and teenagers in the Web of Sciences and PubMed-Medline databases. The titles and abstracts of the studies given will be combed for relevant keywords. The quality of all selected publications will be assessed using the JBI (Joanna Briggs Institute Manual) clinical appraisal checklist for RCTs and non-RCTs. Two authors will independently assess the quality of the work, and any discrepancies will be resolved. Results: A descriptive synthesis will be performed and presented in the form of a narrative summary as tabular format. The summaries will include both narrative descriptions and statistical data from the studies. The meta-analysis will be done for anxiety, depression and stress. Conclusion: This review will help the caretakers (Parents, teachers and mentors etc.,) to acknowledge the importance of incorporating life skills training programs in academics to reach the desired goals of the students. What is already known about the topic?  Many studies have successfully concluded the impact of life skills on an individual's well-being, including the following: Haghighi et al. (2006) showed that life skills training enhances adolescent pupils' mental health and self-esteem. Life skills training improves participants' mental health (family stress and social acceptability), according to Samari and Lalifaz (2005). What this paper adds This review aims to determine the impact of the life skills training program on Psychological well-being (anxiety, depression and stress) among adolescents.

description: Twisted double bilayer graphene has recently emerged as an interesting moiré material that exhibits strong correlation phenomena that are tunable by an applied electric field. Here we study the atomic and electronic properties of three different graphene double bilayers: double bilayers composed of two AB stacked bilayers (AB/AB), double bilayers composed of two AA stacked bilayers (AA/AA) as well as heterosystems composed of one AB and one AA bilayer (AB/AA). The atomic structure is determined using classical force fields. We find that the inner layers of the double bilayer exhibit significant in-plane and out-of-plane relaxations, similar to twisted bilayer graphene. The relaxations of the outer layers depend on the stacking: atoms in AB bilayers follow the relaxations of the inner layers, while atoms in AA bilayers attempt to avoid higher-energy AA stacking. For the relaxed structures, we calculate the electronic band structures using the tight-binding method. All double bilayers exhibit flat bands at small twist angles, but the shape of the bands depends sensitively on the stacking of the outer layers. To gain further insight, we study the evolution of the band structure as the outer layers are rigidly moved away from the inner layers, while preserving their atomic relaxations. This reveals that the hybridization with the outer layers results in an additional flattening of the inner-layer flat band manifold. Our results establish AA/AA and AB/AA twisted double bilayers as interesting moiré materials with different flat band physics compared to the widely studied AB/AB system.

description: This article presents a survey on conditions of small business development. Studies have shown that, among other things, the major constraint for starting and running a business is a financial barrier. In the test environment, in overcoming that barrier, the credit guarantee funds and loan funds play a big role. The main sources of competitiveness of the surveyed companies are price, quality of customer service and quality of product or service. Despite the prevalence of various internal and external constraints, many companies assume stabilization or development of its activities. Entrepreneurs expect it mainly with the support of the local government and the local business environment and growth in demand associated with macroeconomic stability

description: To predict the radiative forcing of clouds it is necessary to know the rate with which ice homogeneously nucleates in supercooled water. Such rate is often measured in drops to avoid the presence of impurities. At large supercooling small (nanoscopic) drops must be used to prevent simultaneous nucleation events. The pressure inside such drops is larger than the atmospheric one by virtue of the Laplace equation. In this work, we take into account such pressure raise in order to predict the nucleation rate in droplets using the TIP4P/Ice water model. We start from a recent estimate of the maximum drop size that can be used at each supercooling avoiding simultaneous nucleation events [Espinosa et al. J. Chem. Phys., 2016]. We then evaluate the pressure inside the drops with the Laplace equation. Finally, we obtain the rate as a function of the supercooling by interpolating our previous results for 1 and 2000 bar [Espinosa et al. Phys. Rev. Lett. 2016] using the Classical Nucleation Theory expression for the rate. This requires, in turn, interpolating the ice-water interfacial free energy and chemical potential difference. The TIP4P/Ice rate curve thus obtained is in good agreement with most droplet-based experiments. In particular, we find a good agreement with measurements performed using nanoscopic drops, that are currently under debate. The successful comparison between model and experiments suggests that TIP4P/Ice is a reliable model to study the water-to-ice transition and that Classical Nucleation Theory is a good framework to understand it.

Data wasobtained from card`s technological developed for the model farms producing crops for energy purposes. They were developed for farms located in 5 macro-regions. The analysis showed that the lowest energy consumption was characterized by the production of farms with an area of 130 ha, both per hectare and per ton of silage obtained. In case of regional analysis, it was found that the main determinant of energy expenditure were obtained yields. Regions obtaining the highest yields of sorghum had the highest energy inputs per 1 ha of crops, but the lowest energy consumption per ton of silage obtained.

description: In 2024, we are entering a year marked by crucial elections in Taiwan, the European Union, and the United States. These elections will significantly influence the global geopolitical landscape and shape the European Union's perspectives and policies regarding China. The persistent tension between the United States and China will continue to mold China's foreign policy. However, deteriorating economic conditions will intensify domestic challenges within Chinese society. At the same time, ongoing conflicts in regions such as Ukraine and the Middle East will undoubtedly impact Europeans' views on China.

MERICS’ survey of 650 China experts and observers suggests that throughout 2024, China will focus on fortifying itself for geopolitical competition. This may play out most intensely in the economic sphere, where Beijing is expected to bolster the party-state’s ability to respond to pressure from the West’s de-risking policies and to steady its domestic economic base. EU-China relations seem to be gradually deteriorating, while 2024 holds significant uncertainties regarding the fallout from EU and US election.

description: Low-energy particle production perpendicular to the event plane in three-jet events produced in Z decays in e+e- annihilation is measured and compared to that perpendicular to the event axis in two-jet events. The topology dependence of the hadron production ratio is found to agree with a leading-order QCD prediction. This agreement and especially the need for the presence of a destructive interference term gives evidence for the coherent nature of gluon radiation. Hadron production in three-jet events is found to be directly proportional to a single topological scale function of the inter-jet angles. The slope of the dependence of the multiplicity with respect to the topological scale was measured to be: 2.211 +/- 0.014 (stat.) +/- 0.053 (syst.) in good agreement with the expectation given by the colour-factor ratio C_A / C_F = 9/4. This result strongly supports the assumption of local parton-hadron duality, LPHD, at low hadron momentum.

description: The gradual accumulation of damage and dysregulation during the aging of living organisms can be quantified. Even so, the aging process is complex and has multiple interacting physiological scales -- from the molecular to cellular to whole tissues. In the face of this complexity, we can significantly advance our understanding of aging with the use of computational models that simulate realistic individual trajectories of health as well as mortality. To do so, they must be systems-level models that incorporate interactions between measurable aspects of age-associated changes. To incorporate individual variability in the aging process, models must be stochastic. To be useful they should also be predictive, and so must be fit or parameterized by data from large populations of aging individuals. In this perspective, we outline where we have been, where we are, and where we hope to go with such computational models of aging. Our focus is on data-driven systems-level models, and on their great potential in aging research.
The Closest View of a Dwarf Galaxy: New Evidence on the Nature of the Canis Major over-density

description: We present a first deep colour-magnitude diagram of the putative central region (0.5 deg x 0.5 deg) of the Canis Major stellar over-density (l,b)=(240,-8) found by Martin et al. (2004), which has been proposed as the remnant of a dwarf satellite accreted onto the Milky Way on a near-equatorial orbit. We find a narrow (in apparent magnitude) main-sequence, extending 6 magnitudes below the turn-off to our limiting magnitude of B ~ 24.5 mag. This main sequence has very high constrast (>3) with respect to the thin/thick disk/halo background; its narrowness at brighter magnitudes clearly implies the presence of a distinct and possibly still bound stellar system. We derived the line-of-sight size (r_{1/2}) of this system based on the B-band width of the lower main sequence, obtaining 0.94 +/- 0.18 (random) +/- 0.18 (systematic) kpc. That size matches a model prediction for the main body of the parent galaxy of the Monoceros tidal stream. The high density contrast and limited spatial extent in the radial direction are very hard to reconcile with the alternative explanation put forward to explain the Canis Major stellar-overdensity: a flared or warped Galactic disk viewed in projection (Momamy et al. 2004). We also derived a central surface brightness of mu_{V,0}= 23.3 +/- 0.1 mag arcsec^{-2} and an absolute magnitude of M_{V}=-14.5 +/- 0.1 mag. These values place the Canis Major object in the category of dwarf galaxy in the the L_{V}--size and M_V - mu_{V} planes for such objects. However, like the Sagittarius dwarf, it is an outlier in the[Fe/H] -M_V plane in the sense that it is too metal rich for its estimated absolute magnitude. This suggests that the main mechanism driving its recent and current star formation history (possibly tidal stripping) is different to that of isolated dwarfs.

description: Sukuk are innovative instruments of the Islamic financial market. They are issued by governments, financial institutions and enterprises primarily from nations belonging to the Organisation of Islamic Cooperation (OIC). What can be observed in recent years, is a growth of interest in sukuk issues also on the part of entities representing Western culture. Broad literature studies conducted by the author have shown a lack of detailed research and analyses regarding the use of the sukuk concept by domestic enterprises. The growing level of trade in agricultural products and foodstuffs with certain Muslim countries was treated in the paper as a factor contributing to the increased interest in the subject of Islamic finance in Poland. The paper intends to determine the potential for using sukuk as a form of obtaining capital by enterprises in the agri-food sector in Poland. The work indicates the characteristics, advantages and risks accompanying the process of sukuk issue in Polish conditions. The lack of knowledge of the rules and realities of the functioning of Islamic finance and high costs of organising a sukuk issue were considered the main factors limiting the supply of the instruments.

Rate equation approach for correlations in growing network models

description: We propose a rate equation approach to compute two vertex correlations in scale-free growing network models based in the preferential attachment mechanism. The formalism, based on previous work of Szabó \textit{et al.} [Phys. Rev. E \textbf{67} 056102 (2002)] for the clustering spectrum, measuring three vertex correlations, is based on a rate equation in the continuous degree and time approximation for the average degree of the nearest neighbors of vertices of degree $k$, with an appropriate boundary condition. We study the properties of both two and three vertex correlations for linear preferential attachment models, and also for a model yielding a large clustering coefficient. The expressions obtained are checked by means of extensive numerical simulations. The rate equation proposed can be generalized to more sophisticated growing network models, and also extended to deal with related correlation measures. As an example, we consider the case of a recently proposed model of weighted networks, for which we are able to compute a weighted two vertex correlation function, taking into account the strength of the interactions between connected vertices.
