description: We present an extensive new time-series of spectroscopic data of the peculiar SN 1999aa in NGC 2595. Our data set includes 25 optical spectra between -11 and +58 days with respect to B-band maximum light, providing an unusually complete time history. The early spectra resemble those of a SN 1991T-like object but with a relatively strong Ca H&K absorption feature. The first clear sign of Si II 6355, characteristic of Type Ia supernovae, is found at day -7 and its velocity remains constant up to at least the first month after B-band maximum light. The transition to normal-looking spectra is found to occur earlier than in SN 1991T suggesting SN 1999aa as a possible link between SN 1991T-like and Branch-normal supernovae. Comparing the observations with synthetic spectra, doubly ionized Fe, Si and Ni are identified at early epochs. These are characteristic of SN 1991T-like objects. Furthermore, in the day -11 spectrum, evidence is found for an absorption feature which could be identified as high velocity C II 6580 or H-alpha. At the same epoch C III 4648.8 at photospheric velocity is probably responsible for the absorption feature at 4500 A. High velocity Ca is found around maximum light together with Si II and Fe II confined in a narrow velocity window. Implied constraints on supernovae progenitor systems and explosion hydrodynamical models are briefly discussed.

description: We propose an image encryption scheme based on quasi-resonant Rossby/drift wave triads (related to elliptic surfaces) and Mordell elliptic curves (MECs). By defining a total order on quasi-resonant triads, at a first stage we construct quasi-resonant triads using auxiliary parameters of elliptic surfaces in order to generate pseudo-random numbers. At a second stage, we employ an MEC to construct a dynamic substitution box (S-box) for the plain image. The generated pseudo-random numbers and S-box are used to provide diffusion and confusion, respectively, in the tested image. We test the proposed scheme against well-known attacks by encrypting all gray images taken from the USC-SIPI image database. Our experimental results indicate the high security of the newly developed scheme. Finally, via extensive comparisons we show that the new scheme outperforms other popular schemes.

description: Stunting, or chronic undernutrition, affects 160 million pre-school children around the world, and imposes significant costs on a child’s health, cognitive development, schooling and economic performance. Most stunting materializes in a very specific age range of 6-23 months when, among other things, children are first introduced to solid foods. But while stunting in this period has been closely linked to generic indicators of dietary diversity, biological studies increasingly link child growth and development to intake of high quality animal-sourced foods (ASFs) rich in protein and other growth-stimulating nutrients. Surprisingly, however, very little experimental research has assessed the impact of ASF consumption on child growth, or explored why ASF consumption is low but also high variable in developing countries. In this paper we redress these knowledge gaps through an analysis of 112,887 children aged 6-23 months from 46 countries. We first document distinctive patterns of ASF consumption among children in different regions, notably the varying importance of dairy and fish in different parts of Africa and Asia, and generally low levels of meat and egg consumption in these regions. We then test how ASF consumption affects child stunting in multivariate models saturated with control variables. We find strong associations with a generic ASF consumption indicator as well as with fish and dairy consumption. Finally, we explore why ASF consumption is low but also so variable across countries and regions. We show that non-tradable ASFs (fresh milk, eggs) are a very expensive source of calories in low income countries, and that caloric prices of these foods are strongly associated with consumption patterns. A host of other demand-side factors are also important, but the strong influence of prices implies an important role for agricultural policies – in production, marketing and trade – to improve the accessibility and affordability of ASFs in poorer countries.

description: Piece-rate compensation is a common feature of developing country labor markets, but little is known about how piece-rate workers respond to incentives, or the tradeoffs that an employer faces when setting the terms of the contract. In a field experiment in rural Malawi, we hired casual day laborers at piece rates and collected detailed data on the quantity and quality of their output. Specifically, we use a simplified Becker-DeGroot-Marschak mechanism, which provides random variation in piece rates conditional on revealed reservation rates, to separately identify the effects of worker selection and incentives on output. We find a positive relationship between output quantity and the piece rate, and show that this is solely the result of the incentive effect, not selection. In addition, we randomized whether workers were subject to stringent quality monitoring. Monitoring led to higher quality output, at some cost to the quantity produced. However, workers do not demand higher compensation when monitored, and monitoring has no measurable effect on the quality of workers willing to work under a given piece rate. Together, the set of worker responses that we document lead the employer to prefer a contract that offers little surplus to the worker, consistent with an equilibrium in which workers have little bargaining power.

description: This study is devoted to the creation of the competitive position of the organization, which is a non-public higher education unit through the use of intangible capital, especially human capital and social capital. The study was based on the subject literature and authors’ own research among members of the academic community (personnel and students ). The work presents theoretical aspects of competitiveness, features of contemporary organization in light of the challenges of global competition, the characteristics of the examined university and its position on the education market. The empirical part presents the results of the competitiveness of universities in the opinions of personnel and students. Studies show that a new reality based on the increasing competition to gain students and the extension of the educational services market forces universities to experience the need to explore new ways to develop and maintain competitiveness. Human capital and its proper use is a valuable resource and is the basis for achieving competitiveness.

COMPETITIVENESS OF EUROPE IN MANUFACTURE OF CHEMICALS IN THE CONDITIONS OF GLOBALIZATION

description: In modern times we can observe the growing process of globalization of economic activity that takes place at all levels of companies, markets, industries and the economy as a whole. This article assumes the perspective of one of the branches of economy which is the chemical industry. The key aspect of functioning in an increasingly internationalized economy is competitiveness. When considering the issue of competitiveness in a global context it is worth going beyond individual organizations and analyze it from the perspective of countries and regions (understood as groups of countries). The purpose of this article is to assess the competitiveness of the European region in the global market of chemical products. The selection of the region and the branch was not randome. In this study the method of literature studies, secondary data collected and published by the European Chamber of Chemical Industry, the Bureau of Labor statistics and the data of the World Bank, as well as the method in the area of strategic management, ie a gap analysis were applied. European countries, and in particular the EU-27, have a gap deficiency in relation to the pace of development of the global market for chemical products. As a result, the EU-27 is rapidly losing share in the world market. The strategic position of the EU-27 dramatically weakened, which means reducing the competitiveness of the EU-27 compared to other regions of the world. Key reasons for this phenomenon should be sought on the one hand in the high labor costs, but also in restrictive policies regarding the environment and safety leading to a phenomenon that can be described as „hyper-regulation”. The European Union imposing restrictive regulations seems to rely on increasing the competitiveness of European enterprises as a result of the development of environmentally friendly technologies. The problem, however, of this policy is deterioration of the competitive position of „hyper-regulation” of EU companies in the short term without the guarantee of building a competitive advantage in the future.

description: Based on a detailed modeling of the Fermi surface topology of MgB2 we calculated the anisotropy of the upper critical field Bc2 within the two gap model. The sigma-band is modeled as a distorted cylinder and the pi-band as a half-torus, with parameters determined from bandstructure calculations. Our results show that the unusual strong temperature dependence of the Bc2 anisotropy, that has been observed recently, can be understood due to the small c-axis dispersion of the cylindrical Fermi surface sheets and the small interband pairing interaction as obtained from bandstructure calculations. We calculate the magnetic field dependence of the density of states within the vortex state for field in c-axis direction and compare with recent measurements of the specific heat on MgB2 single crystals.

description: The aim of this study was to evaluate the activation of resources as a source of competitive advantage between regions of Eastern Poland in 2008 and 2010. Studies have been made on the basis of the CSO figures for the provinces, and thus are fully credible. For the purpose o f realizing the study the following research methods were used: qualitative and quantitative, horizontal and vertical analysis as well as the comparative method. The study shows that economic and social cohesion of the eastern Polish regions with other regions in Poland is weakening. This is limiting their growth and competitiveness. The competitiveness between the Polish and Eastern provinces is at a similar level. This is determined by the similarity regarding: 1) the amount of remuneration for work, 2) the structure of branch management, 3) gross value added per employee, 4) low demand for products and services. The indicated conditions in these regions justify cooperation between them to a larger extend than their competition. From the theory of the system and the conducted analysis it may be observed that the competitive advantage between regions should be determined with the help of the newly created value per worker. The hierarchy of provinces according to this criterion is as follows, starting from the highest value: 1) Warmian-Mazurian, 2) Podlaskie, 3) Holy Cross, 4) Subcarpathian, 5) Lublin. A key growth strategy in the surveyed provinces was based on increasing the value of capital (extensive factor) and decreasing employment in the situation of increased unemployment (intensive factor). In the face of low-wages conditions this strategy has proven to be ineffective.

description: Filament eruptions occurring at different places within a relatively short time internal, but with a certain physical causal connection are usually known as sympathetic eruption. Studies on sympathetic eruptions are not uncommon. However, in the existed reports, the causal links between sympathetic eruptions remain rather speculative. In this work, we present detailed observations of a sympathetic filament eruption event, where an identifiable causal link between two eruptive filaments is observed. On 2015 November 15, two filaments (F1 in the north and F2 in the south) were located at the southwestern quadrant of solar disk. The main axes of them were almost parallel to each other. Around 22:20 UT, F1 began to erupt, forming two flare ribbons. The southwestern ribbon apparently moved to southwest and intruded southeast part of F2. This continuous intrusion caused F2's eventual eruption. Accompanying the eruption of F2, flare ribbons and post-flare loops appeared in northwest region of F2. Meanwhile, neither flare ribbons nor post-flare loops could be observed in southeastern area of F2. In addition, the nonlinear force-free field (NLFFF) extrapolations show that the magnetic fields above F2 in the southeast region are much weaker than that in the northwest region. These results imply that the overlying magnetic fields of F2 were not uniform. So we propose that the southwest ribbon formed by eruptive F1 invaded F2 from its southeast region with relatively weaker overlying magnetic fields in comparison with its northwest region, disturbing F2 and leading F2 to erupt eventually.

description: We present the results of our analysis of the photometric data of globular clusters in the elliptical galaxy NGC 5128 (Cen A). We show that the integrated colour U-B can be an effective metallicity indicator for simple stellar populations. This is because it is sensitive to metallicity via the opacity effect but relatively insensitive to the effective main sequence turn-off temperature of the population (and thus to age) when Teff ~ 7000-12000K, that is, when the Balmer Jump is strong. This flat U-B vs Teff relation is a result of the fact that the blueing effect of the optical continuum with increasing temperature is temporarily stopped by the Balmer Jump which becomes greater with temperature in this range. In this study we use U-B and B-V as metallicity and age indicators, respectively. We first show that the use of the U-B vs B-V two-colour diagram roughly yields the metallicities and ages of the Milky Way globular clusters independently determined, and then apply the technique to the clusters in NGC 5128. There is a large range in U-B, which corresponds to [Fe/H] of -2.0 through over +0.3. The large uncertainties from the data and the models currently prevent us from pinning down their ages and metallicities. Although a constant age for all these clusters cannot be ruled out, there is a hint of the metal-rich clusters being younger. Significance of these results and caveats of the analysis are discussed.

description: In this paper, a quantitative characterization for the evolutionary sequence of stellar self-gravitating system is investigated, focusing on the pre-collapse stage of the long-term dynamical evolution. In particular, we consider the quasi-equilibrium behaviors of the N-body systems in the setup of the so-called Antonov problem, i.e., self-gravitating N-body system confined in an adiabatic wall and try to seek a possible connection with thermostatistics of self-gravitating systems. For this purpose, a series of long-term N-body simulations with various initial conditions are performed. We found that a quasi-equilibrium sequence away from the thermal equilibrium can be characterized by the one-parameter family of the stellar models. Especially, the stellar polytropic distribution satisfying the effective equation of state $P\proptoρ^{1+1/n}$ provides an excellent approximation to the evolutionary sequence of the N-body system. Based on the numerical results, we discuss a link between the quasi-equilibrium state and the generalized thermostatistics by means of the non-extensive entropy.

title: Reflective Learning: Adding Value to the Openings Experience?
Creators: name: Alden, Bethany
Publisher: name: The Open University
Year: 2009

description: Thinkers have long sought to illuminate the ways in which the practical is linked to the theoretical. There are many instances of where these ideas have involved the activity of reflection in transforming experience into knowledge (Habermas, 1974; Van Manen, 1977; Kolb, 1984). More recently, models of reflective learning have proposed that critical reflection is a requisite for ‘transformational endeavours’ such as higher learning (Brockbank and McGill, 1998, p. 53).

Work done by the Centre for Widening Participation (CWP) at the Open University offered an opportunity to study reflective learning in higher education. As a point of entry for Open University study and as a bridge into higher education for students with low educational qualifications, the Openings programme within CWP may be the first experience some learners have had with reflective learning at this level. This dissertation employs a qualitative approach as it tries to illuminate this phenomenon by looking at the extent to which Openings students feel the reflective tasks have added value to their learning experience.

Data were collected from twelve recent Openings students through the use of telephone interviews. Participants’ responses were analysed across four sub-questions that dealt with: 1) understanding reflective learning 2) orientating to reflective learning 3) valuing reflective writing and 4) perceiving the role of the tutor in promoting reflective learning.

Findings suggested that some Openings students find reflective tasks challenging when they are presented as self-assessment exercises. Some learners rank reflective tasks as a lower priority because they are presented as separate to the content-based tasks and because some of the reflective work is not assessed. Some respondents perceive reflective tasks as pointless activities because it keeps them from the actual coursework. Finally, Openings students seem to be dependent on written feedback from the tutor in order to fully engage in the reflective learning activities.

description: The work presents the environmental and organizational-economic considerations of competitiveness of Lublin voivodeship’s agriculture. Production and economic results in contrast to Polish averages are discussed. The analysis was conducted on the basis of averages from 2010 - 2012. It has been established that the organizational and economic conditions and considerably high internal diversity of agriculture within the voivodeship’s limits are the deciding factors of the competitiveness and relatively low use of this region’s agricultural potential. In contrast to the rest of Poland, Lublin Voivodeship, although having advantages in some segments of production, mainly fruits, vegetables, and industrial crops, and taking into consideration the fact that it has potentially higher quality of agricultural productive area and work supplies, the region has considerable potential, but its use in many branches of agricultural production has been limited in recent years. Internal diversity within the limits of this region of this voivodeship also influences its agricultural position. Huge scale of negligence, threats to ecosystems, and bad productive-economic situation prove that there is a necessity of definite implementation of technological progress in agriculture, improvement of soils’ agro-chemical condition, development and modernization of rural areas and farms’ infrastructure, and financial support of all ventures which determine realization of conception of balanced development and accelerate the reconstruction of agrarian structure, as well as increase of competitiveness.

description: We consider modified Weyl gravity where a Dirac spinor field is nonminimally coupled to gravity. It is assumed that such modified gravity is some approximation for the description of quantum gravitational effects related to the gravitating spinor field. It is shown that such a theory contains solutions for a class of metrics which are conformally equivalent to the Hopf metric on the Hopf fibration. For this case, we obtain a full discrete spectrum of the solutions and show that they can be related to the Hopf invariant on the Hopf fibration. The expression for the spin operator in the Hopf coordinates is obtained. It is demonstrated that this class of conformally equivalent metrics contains: (a) a metric describing a toroidal wormhole without exotic matter; (b) a cosmological solution with a bounce and inflation; and (c) a transition with a change in metric signature. A physical discussion of the results is given. \end{abstract}

description: The aim of this study was to evaluate the agri-ecological potential of agriculture in terms of regions on the voivodeship level. The source of data was the analyses made by Central Statistical Office (GUS) (2010-2012) and the study’s results presented in publications connected with the discussed issues. In the paper, three scopes of evaluation were made, which were further characterized by specific indices. They include the quality of agricultural area (environment), the state of soil covering with flora and the agrichemical state of the soil. After expressing the partial indices’ value by 5o point-based scale and their verification (number reduction and indices’ aggregation) the agri-ecological potential of agriculture by means of synthetic scoring index was assessed. Four voivodeships excelled in the most favourable quality of agricultural area, i.e. Opole Voivodeship, Lower Silesian Voivodeship, Kuyavian-Pomeranian Voivodeship and Lublin Voivodeship whereas the worst conditions to agricultural production were identified in two voivodeships – Masovian and Podlaskie. The best state of soil covering with flora was found in Lubush and Warmian-Masurian Voivodeship while the worst index of soil protection in terms of flora function was noted in Lublin and Holy Cross Voivodeship. With respect to the agrichemical state of the soil the best assessment was given to Opole and Lower Silesian Voivodeship whereas the lowest notes were reported in Masovian and Podlaskie. In the synthetic view (three scopes of evaluation) the most favourable index of agri-ecological potential was reported in case of two voivodeships – Opole and Lower Silesian while definitely the worst with regard to Masovian and Podlaskie. Low evaluation of the agri-ecological potential results mainly from the low quality of the agricultural area as well as unfavourable agrichemical state of the soil in abovementioned voivodeships.

description: We define a new family of multivariate stochastic processes over a finite time horizon that we call Generalised Liouville Processes (GLPs). GLPs are Markov processes constructed by splitting Lévy random bridges into non-overlapping subprocesses via time changes. We show that the terminal values and the increments of GLPs have generalised multivariate Liouville distributions, justifying their name. We provide various other properties of GLPs and some examples.
title: An Exploration of the Change of Teacher Assessment Practice, in Physical Education at Key Stage 3, between 2000 and 2005/2006

description: Teacher assessment has been the ‘modus operandi’ in Physical Education (PE) since its inclusion as a foundation subject in the National Curriculum in 1992, yet the Office for Standards in Education (Ofsted) has consistently reported that assessment in this subject is problematic (1995, 1998, 2003, 2009). This research focuses on schools involved in initial teacher education and training, in partnership with Riverside University. Using an overarching case study strategy and a mixed methods approach to data collection and analysis (Yin, 2003), this longitudinal study explores the changes in teachers’ assessment practice in PE at Key Stage 3, over a seven-year period, at a time of unprecedented reform of teacher assessment and its relationship with learning at national level (Black and Wiliam, 1998a; DfES 2004; ARG, 1999 -2010). Using the work of Harlen (2004a) as a tool for analysis, it demonstrates that within the framework of NCPE (2000), at the three data collection points (2000, 2005 and 2006) PE teachers, in the Riverside Partnership, are using an ever-wider range of methods and tools, in order to make dependable assessment judgements at Key Stage 3. There is evidence that teacher assessment practice in PE has developed in line with current thinking at national level, particularly in terms of involving the pupils in their own assessment to inform their learning. However, teacher observation remains the dominant assessment mode. The study concludes that driven by the prevailing culture of performativity and accountability (Broadfoot, 2000b; Ball, 2003) in the schools in which the teachers were working, the PE teachers’ assessment practice increasingly moved towards the notion of ‘good practice’ in assessment in PE, as defined by Ofsted (2003b). However, given that teacher assessment practice continues to vary across the schools in the partnership, issues of consistency remain for the initial teacher training of the PE student teachers.
TOURIST POTENTIAL AS AN ELEMENT OF COMPETITIVENESS OF RURAL AREAS ON THE EXAMPLE OF SUBCARPATHIAN REGION

description: In the study, selected aspects were presented concerning the assessment of tourist potential of communes in the context of shaping their competitiveness. Against the background of theoretical considerations one’s own proposal was presented on measurement of tourist potential of rural communes, constituting a modification of the method of G. Gołembski. The changes made by the author result mainly from the specifics of rural areas and technological progress. The values of measurement factors presented which characterize a tourist attractiveness of communes in Subcarpathian region point out for potentially high possibilities of development of rural tourism. Unfortunately, in the quantity approach the Subcarpathian region is located on a quite high position on a scale in the whole country, this however is a low attractive quality offer which makes that rural tourism is low competitive against the background of other regions. Most often chances of tourist development are ascribed to endogen resources including especially natural and cultural ones. In the meantime, experiences of other regions indicate that the success of a given region depends not only on natural attractions or cultural heritage, but more and more often creativity, ability to cooperate and determination of persons and entities involved in the development of rural tourism. Among many decisions and activities of strategic and organizational nature, in the opinion of the author on the basis of the research conducted, one may point out six, basic elements which raise tourist competitiveness (so called 6 „P” of rural tourism): social participation, ideas, positioning, partnership, offer package and promotion.
Novel surface anisotropy term in the FMR spectra of amorphous microwires

description: Some recent publications on ferromagnetic resonance in amorphous wires mention presumably new kind of anisotropy, called there circumferential anisotropy, as an explanation of various spectral features. In this paper we argue that there is no special reason to speak of the new kind of anisotropy, since the observed spectra can be well described in terms of more traditional uniaxial and surface anisotropies alone.

title: The Pope of YouTube: A Case Study of Dynamic Metaphor Use in Asynchronous Internet Communication
Creators: name: Pihlaja, Stephen

Year: 2009

description: Research into computer-mediated communication has recently focused on large quantitative analysis of CMC text rather than close analysis of full discourse acts in online environments. Using a discourse dynamics, metaphor-led analysis, this dissertation investigates the dynamic use of metaphor in three YouTube videos made by two American YouTube users: one a fundamentalist Christian and one an atheist. The focus of the analysis was on how metaphor was produced dynamically in the interaction between the users and how the use of metaphor could be seen at different levels of the YouTube video page, including in the title of the videos, the video, the description boxes, the comments, and subsequent video responses. Analysis showed that metaphor was used at every level of the discourse event and that dynamic production of metaphor in response to other users was seen, especially in discussing the positions and roles of the users in relation to each other and the larger YouTube ‘community. ’ Analysis also showed that metaphor was used to not only position other users, but that understanding of specific metaphors seemed to differ depending on who was producing and interpreting a given metaphor.

description: Pig farming in the Republic of Croatia is an important animal farming branch supplying quality meat to consumers. In this paper, the development of pig farming in Croatia and the EU countries is described. The aim of the paper is to research the development of pig farming in the period from 2010 to 2016 – three years after Croatian accession to the EU – and compare the Croatian data with the state of pig farming in the EU countries. Due to the lack of increase in domestic production, Croatian accession to the EU did not have a positive impact on the development of pig farming.
