The paper focuses on the role of the Swedish spatial particles upp ‘up’ and ner ‘down’ to signal the endpoint-of-motion in the description of motion situations and is based on Swedish original fiction texts and their translations into English, German, French and Finnish. Frequently the endpoint is marked with a locative preposition such as på ‘on’ or i ‘in’, and then a particle is required to signal change-of-place. In German and Finnish, the particle is often zero translated and change-of-place is indicated by case. The particle is often zero translated also in French, a V(erb)-framed language. This leads to contrasts at the conceptual level since verticality is not expressed. The result points to radical intra-typological differences between S(atellite)-framed languages in the expression of Path depending on general morpho-syntactic differences. Another important conclusion is that several different classes of motion verbs must be distinguished even in S-languages to describe the expression of change-of-place.

AbstractUnusual features in the Hall Resistivity of thin film systems are frequently associated with whirling spin textures such as Skyrmions. A host of recent investigations of Hall Hysteresis loops in SrRuO3 heterostructures have provided conflicting evidence for different causes for such features. We have constructed an SrRuO3-PbTiO3 (Ferromagnetic – Ferroelectric) bilayer that exhibits features in the Hall Hysteresis previously attributed to a Topological Hall Effect, and Skyrmions. Here we show field dependent Magnetic Force Microscopy measurements throughout the key fields where the ‘THE’ presents, revealing the emergence to two periodic, chiral spin textures. The zero-field cycloidal phase, which then transforms into a ‘double-q’ incommensurate spin crystal appears over the appearance of the ‘Topological-like’ Hall effect region, and develop into a ferromagnetic switching regime as the sample reaches saturation, and the ‘Topological-like’ response diminishes. Scanning Tunnelling Electron Microscopy and Density Functional Theory is used to observe and analyse surface inversion symmetry breaking and confirm the role of an interfacial Dzyaloshinskii–Moriya interaction at the heart of the system.

The purpose of this paper is to review current literature on knowledge management and highlight the importance of knowledge audit in bringing about a holistic knowledge solution to knowledge management. Based on the review of literature on knowledge management, this study points out the role of knowledge audit in solving the challenges in organizations’ tacit and explicit knowledge. Specifically, the paper concentrates on knowledge audit, knowledge risk and international and national standards on knowledge audit processes. The contribution of this study to literature are the suggestions that knowledge risk and international standards procedures could be applied to knowledge audit. The important conclusion of this paper is that knowledge risk management has not been fully explored in the study of knowledge audit. The paper addresses the research question of what organizations must embark on in the process of knowledge audit. The paper attempts to provide answer to the question by highlighting the importance of knowledge audit and the reasons why organizations carry out knowledge audit, and also the existing knowledge audit frameworks and methodologies.

Local Spin

<p>We now show that Clark and Davidson local spins operators are perfectly defined subsystem operators if a fragment is taken as an <i>open quantum system</i> (OQS). Open systems have become essential in quantum control and quantum computation, but have not received much attention in Chemistry. We have already shown (<i>J. Chem. Theory Comput</i>. <b>2018</b>, <i>15</i>, 1079) how real space OQSs can be defined in molecular systems and how they offer new insights relating quantum mechanical entaglement and chemical bonding. The OQS account of local spin that we offer yields a rigorous, yet easily accessible way to rationalize local spin values. A fragment is found in a mixed state direct sum of sectors characterized by different number of electrons that occur with different probabilities. The local spin is then a weighted sum of otherwise standard <i>S</i>(<i>S</i>+1) values. With OQS glasses, it is obvious that atomic or fragment spins should not vanish. Our approach thus casts doubts on any procedure used to annihilate them, like those used by Mayer and coworkers. OQS local spins allow for a fruitful use of models. One can propose easily sector probabilities for localized, covalent, ionic, zwitterionic, etc. situations, and examine their ideal local spins. We have mapped all 2c-2e cases, and shown how to do that in general multielectron cases. The role of electron correlation is also studied by tuning the Hubbard U/t parameter for H chains. Correlation induced localization changes the spin-coupling patterns even qualitatively, and show how the limiting antiferromagnet arises.</p>

Source Program

To be a debugger is a good thing! Since the very beginning of the programming activity, debuggers are the most important and widely used tools after editors and compilers; we completely recognize their importance for software development and testing. Debuggers work at machine level, after the compilation of the source program; they deal with assembly, or binary-code, and are mainly data structure inspectors. ALMA is a program animator based on its abstract representation. The main idea is to show the algorithm being implemented by the program, independently from the language used to implement it. To say that ALMA is a debugger, with no value added, is not true! ALMA is a source code inspector but it deals with programming concepts instead of machine code. This makes possible to understand the source program at a conceptual level, and not only to fix run time errors. In this paper we compare our visualizer/animator system, ALMA, with one of the most well-known and used debuggers, the graphical version of GDB, the DDD program. The aim of the paper is twofold: the immediate objective is to prove that ALMA provides new features that are not usually offered by debuggers; the main contribution is to recall the concepts of debugger and animator, and clarify the role of both tools in the field of program understanding, or program comprehension. .

This article compares two first-century authors, Paul and Plutarch, on the mechanics of inspiration and the role of gender in the prophetic process. Paul's First Corinthians and Plutarch's Delphic Dialogues (De Pythiae oraculis and De defectu oraculorum) were written by men who were observers of and commentators on the religious phenomenon of prophecy – that is, the communication of divine messages through human speakers. They also make statements about women that indicate that gender influenced their perceptions of prophecy. When these authors discuss prophecy at the conceptual level, gender does not affect their arguments, but when they turn to actual women prophets, they introduce ideas about gender and sex that shape their views of the prophetic process and the women who prophesy.

The Impact

PurposeThe first goal of the article was to examine how the perception of the role and scope of operation of maintenance services in the enterprise changes, depending on whether the company has an integrated management system (IMS), only a quality management system implemented in accordance with ISO 9001 and in the absence of a formal, certified management system. The second goal was to propose a model for assessing the quality of maintenance service functioning in enterprise with IMS implemented.Design/methodology/approachThe author's experience of over 1,000 audits in enterprises in various industries: food, automotive, construction, petrochemical, electronic and so on was used in the work. The audits were carried out in three types of companies: which had IMSs (800 audits), which only had a system implementation certificate ISO 9001 (140 audits) and without any standardized management system implemented (so-called second-party audits, commissioned by the client of the audited company.FindingsThe most important conclusion is – the role of UR services in enterprises with the implemented IMS is much broader and goes beyond the classic framework for planning, implementation and settlement of maintenance and repair work. Maintenance is understood more broadly and includes in its scope also the safety of people and the environment, the efficiency of production and consumption of utilities as well as the quality of products and services. Maintenance issues include not only strictly technical aspects but also economic, logistic, legal and organizational and management aspects.Practical implicationsResearch shows that enterprises, especially those with high technical and organizational culture, should not treat management systems as costs, but as a driving force for the implementation of new technologies, new organizational solutions and the development of employees' competences.Social implicationsBroad views on stakeholders of maintenance services (including employees, their families, control institutions) and their requirements make enterprises begin to see the need to maintain the so-called lifetime balance, as well as the safety and comfort of work of employees of these services.Originality/valueThe author did not find in literature any reports on studies of the impact of formal, certified management systems on the quality of maintenance services; this article shows that this impact is large and, above all, positive; with such a broad understanding of the role of maintenance, there is a need to develop a common platform for such seemingly distant concepts as machine technical condition or fatigue life versus cost accounting and quality management.

General Explanation

The dominant role of comparative physiology (syn. experimental zoology) in the recent history of animal biology is noted. Its objectives, e.g. of contributing to knowledge of phylogenetic relationships and of discovering the origins of physiological functions, are considered to have been largely illusory when the data are examined. It is argued that in reality comparative physiology is concerned only with the description of adaptations, albeit at a sophisticated technical and conceptual level compared with natural history or general morphology. Comparative physiology has not produced any special theory or general explanation for physiological adaptation going beyond Darwin's general theory of natural selection.

Tv Broadcasting

This paper has two purposes: one conceptual and the other practical. On a conceptual level, it outlines a model for understanding how TV operates as a social mediator in the event of natural disasters, and at the practical level, it recommends measures that can be used to optimize the role of TV and its ideal social function in contexts of crisis. This model views TV intervention as both «self-centered», that is, driven by its reproduction as a media consumption company; and «socially-centered», designed to respond swiftly and accurately to the social requirements that emerge in crisis situations. The suggested model is to be contrasted with the results of a research study conducted by the National TV Council of Chile that explored the role of TV broadcasting after the earthquake in February 2010. According to the results of the study, audiences value the amount of information broadcasted by TV networks but perceive that the predominance of its «self-centered» function creates a problem: the logic of the 'spectacle' is prevalent and exacerbates the audience’s emotions. The primary purpose of this paper is to develop a strategy to recommend how TV and its associate services can respond to a crisis situation while respecting the tragedy of natural disasters.Este trabajo contempla a la vez un propósito conceptual y otro de orden práctico. En lo conceptual se propone un modelo para comprender el funcionamiento de la televisión en escenarios de catástrofe y consecutivamente se sugiere, desde este modelo, un conjunto de derivaciones prácticas destinadas a optimizar la funcionalidad de la televisión en estos escenarios. El modelo propuesto concibe la intervención televisiva con una doble funcionalidad, una de carácter «autocéntrico» focalizada en su reproducción como empresa y otra de carácter «sociocéntrico» orientada a responder a los requerimientos surgidos en el escenario de la crisis. Este modelo será contrastado con los resultados de un estudio del Consejo Nacional de Televisión de Chile que indagó sobre el rol que asumió la televisión en el terremoto acaecido en Chile el año 2010. Según este estudio, si bien se valora el rol informativo y orientador de la televisión, la doble funcionalidad de su intervención fue percibida como problemática, con predominio de la funcionalidad autocéntrica que, desde una lógica de la espectacularidad, buscó construir audiencias, empleando una estrategia basada en la hiperactivación emocional. Finalmente, se concluye con una propuesta para conducir la televisión desde una intervención en la crisis hacia una efectiva intervención en crisis optimizando su funcionalidad sociocéntrica.

By paying attention to the hole-doped two-dimensional systems of antiferromagnetically (strongly) correlated electrons, we discuss the cause of hole-rich phase formation in association with phase separation. We show that the phase diagram obtained from Maxwell's construction in the plane of temperature vs. hole density is consistent with one derived from the evaluation of hole-rich and electron-rich phases in real space. We observe that the formation of a hole-rich phase is attributed to the aggregation of hole pairs induced by spin singlet pairs present in the pseudogap phase, and that the direct involvement of correlations between hole pairs is not essential for phase separation.

The paper implements an institutional and functional approach to determining the place and role of insurance in shaping a “green” economy. The ways of integrating it as a constituent element of the financial system have been considered. The views of scientists involved in various aspects of modelling the “green” economy on the functional utility of insurance have been summarised. The use of the term “green insurance” and the meanings it implies have been analysed. The author has concluded that the relevant concept of “green insurance” is not yet so unambiguous that it can be used as a scientific concept. Another important conclusion that has been brought up for discussion is that the potential of insurance as a risk management tool within the green economy strategy is not to be confined to environmental insurance, but should be considered in expanding its scope of application to include both the fuller coverage of risk carriers and the range of potential hazards.
