Mosaic arthroplasty of the medial femoral condyle in horses - an experimental study.

One Arabian and 5 Hungarian half-bred horses were used to study the macroscopic and microscopic survival of autologous osteochondral grafts in the weight-bearing surface of the medial femoral condyle (MFC). Grafts were harvested from the cranial surface of the medial femoral trochlea (MFT) under arthroscopic control. Three of them were transplanted into the weight-bearing surface of the contralateral MFC using an arthrotomy approach. Three months later this transplantation procedure was repeated on the opposite stifle joints in the same animals, but at that time transplantation was performed arthroscopically. Follow-up arthroscopy was carried out 12 months after the first operations, and biopsies were taken from both the recipient and the donor sites for histological examination. During follow-up arthroscopy, the transplanted areas looked congruent and smooth. Microscopically, the characteristics of hyaline cartilage were present in 5 out of the 10 biopsies examined; however, in the other half of biopsies glycosaminoglycan (GAG) loss and change in the architecture of the transplanted cartilage was observed. In a 16-year-old horse, all grafts broke during harvesting, and thus transplantation was not performed. No radiological signs of osteoarthritic changes were detected 9 to 12 months after the operations in the donor and recipient joints. Clinically, no lameness or effusion was present three months after the transplantations.

Rocks are human beings: researching the humanizing metaphor in earth science scientific texts

This paper describes a corpus-based analysis of the humanizing metaphor and supports that constitutive metaphor in science and technology may be highly metaphorical and active. The study, grounded in Lakoff’s Theory of Metaphor and in Langacker’s relational networks, consists of two phases: firstly, Earth Science metaphorical terms were extracted from databases and dictionaries and, then, contextualized by means of the “Wordsmith” tool in a digitalized corpus created to establish their productivity. Secondly, the terms were classified to disclose the main conceptual metaphors underlying them; then, the mappings and the relational networks of the metaphor were described. Results confirm the systematicity and productivity of the metaphor in this field, show evidence that metaphoricity of scientific terms is gradable, and support that Earth Science metaphors are not only created in terms of their concrete salient properties and attributes, but also on abstract human anthropocentric projections.

Entorno histórico y social de la aparición del microchip

El siguiente proyecto es un desarrollo histórico-científico acerca de la notoria importancia que supuso la aparición del microchip o circuito integrado1. El desarrollo de este trabajo ha sido una investigación bibliográfica en contenidos webs, enciclopedias y libros. El trabajo contiene un estudio sobre los transistores que fue el componente que dio paso al circuito integrado además de ser uno de los mayores inventos del siglo XX, además, se propone una pequeña inmersión a la época histórica del momento de la aparición del transistor. Al igual que con el transistor, se hace un estudio acerca del circuito integrado, pero en este caso siendo más extenso ya que es el objeto de estudio de este PFC. Para este componente sí que podemos encontrar una explicación más exhaustiva acerca de su fabricación, materiales. Además también podemos encontrar el momento históricosocial de la época bajo estudio. Para finalizar con el proyecto, se hace un breve repaso de los ejemplos de aplicación del circuito integrado y así poder hacer hincapié de la revolución tecnológica que supuso el descubrimiento del microchip. ABSTRACT. The following work is a historical and scientific development regarding the fundamental importance the emergence of the microchip. The development of this work has consisted of a bibliographic research of web contents, encyclopedias and books. The paper contains a study about the transistors, component that propitiated the integrated circuit and was one of the most important inventions of the XXth century. Also is proposed a short historical immersion in the time that preceded the coming of the transistor. As well as with the transistor, a study of the integrated circuit is carried out, yet with deeper insight, for that is the central aim of this Final Project report. For this component a more exhaustive explanation of its manufacture process, materials and theories can be provided. Also, the historical and social of that time is described. To complete the report, a brief review is done about examples of applications of the integrated circuit and thus highlight the technological revolution that the microchip development brought.

Matematikaoktatás a bolognai típusú gazdasági képzésekben (Maths instruction in Bologna-type economics tuition)

A gazdálkodási és közgazdasági alap- és mesterszakok tanterveiben számos matematikai tárgy szerepel. A kétciklusú bolognai képzésre történő áttérés Európa-szerte igényelte a matematikaoktatás szerkezetének, mennyiségének és mélységének újragondolását a gazdálkodási és közgazdasági képzési területeken. Mivel az átállás országonként és intézményenként párhuzamosan és jelentős mértékben egymástól függetlenül ment végbe, egyetemenként számos eltérő megoldással találkozhatunk. Az egyetemek operatív tanterveit és tantárgyi adatlapjait felhasználva, utólagosan már összehasonlítható az egyes egyetemek matematikaoktatása. A tanulmány a matematika közgazdaságtanban betöltött szerepének áttekintése után a vezető európai egyetemek és négy magyar egyetem gazdálkodási és közgazdasági képzésén folyó matematikaoktatásának összehasonlító elemzése alapján arra az alapvető következtetésre jut, hogy Magyarországon a vizsgált képzési területen a matematikaoktatás mennyiségileg és minőségileg kritikus szintre süllyedt. / === / The basic and master's curricula for business and economics include plenty of mathematics subjects. Business and economics courses had to be rethought when the change was made across Europe to the two-cycle Bologna system. This change took place simultaneously but independently in each country and institution, so that notably different solutions can be found in each university. A retrospective comparison of maths instruction in various universities can be made by examining their operative syllabuses and subject data-sheets. The study reviews the part mathematics plays in economics, then uses comparative analysis of the maths teaching in business and economics courses at leading European and four Hungarian universities to reach a general conclusion: maths teaching in Hungary, in the field examined, has sunk to a critical level, in terms of quality and quantity.

Vertikális korlátozások - növelik vagy csökkentik a jólétet? Érvek az irodalomból = Vertical constraints - do they increase or reduce welfare? Arguments in the literature

A vertikális korlátozások témaköre a versenypolitika és -szabályozás egyik legfontosabb, de mindenképpen legtöbb vitát generáló területe. A téma magyar irodalma elsősorban elméleti kérdésekkel foglalkozik, mellőzve a konkrét iránymutatásokat a probléma kezelésére. Először röviden bemutatjuk a vertikális korlátozások indokait és hatásmechanizmusát magyarázó teoretikus irodalmat, felsorolva azok hatékonyságnövelő hatását hangsúlyozó érvrendszereket, illetve a versenykorlátozás lehetőségét tárgyaló modelleket is. Ezután bemutatjuk, hogy milyen fontos empirikus vizsgálatokat végeztek ezen elméletek vizsgálatára, és milyen következtetések vonhatóak le a tapasztalatokból. _________ The field of vertical constraints is one of the most important in competition policy and regulation, but one that generates the most debate. Hungarian literature on the subject deals primarily with theoretical questions, refraining from offering specific guidelines for handling the problem. The paper first covers briefly the causes of the vertical constraints and the Hungarian theoretical literature on its effective mechanism, listing the system of arguments that point to its effect of increasing efficiency and the models that discuss the possibility of limiting competition. The paper then presents the major empirical examinations made of these theories and the conclusions drawn from that experience.

How Corporate Executives Perceive Environmental Issues

This article reports the results of a survey conducted in Hungary to compare the environmental perceptions of Hungarian corporate managers with those of other executives from around the world who had earlier responded to a similar survey conducted by McKinsey and Company. The results showed virtually no differences in how Hungarian managers perceived the importance of environmental challenges, but they did reveal stronger differences in perceptions between Hungarian and international respondents and among Hungarian respondents from companies in different owner.

A központi bankok társadalmi felelőssége (Social responsibility of central banks)

A szerzők tanulmányukban bemutatják a vállalati gyakorlatból ismert vállalati társadalmi felelősségvállalás (CSR) koncepció lehetséges központi banki értelmezését, kitérve a központi bankok gazdasági, jogi, etikai és filantróp (jótékonysági) felelősségére. Megközelítésüket az amerikai (FED), az európai (EKB) és a magyar (MNB) központi bank gyakorlatán keresztül mutatják be. Dolgozatuk alapgondolata, hogy egy valóban felelős intézmény minden rendelkezésére álló eszközzel a társadalmi jólétet segíti elő, ahogy a társadalom tagjai vonatkozásában Adam Smith megfogalmazta bő kétszáz évvel ezelőtt. ____ This paper studies a possible interpretation of Corporate Social Responsibility (CSR) known from business translated to the sphere of central banks, including the central banks’ economic, legal, ethical, and philanthropic (charity) responsibilities. The authors’ approach is presented through practices of the American (FED), the European (ECB), and the Hungarian (MNB) Central Banks. The main idea in this paper is that a responsible organisation uses all means possible to improve social wealth, as stated by Adam Smith in relevance to the members of the society over two hundred years ago.

Work-to-family spillover: Gender differences in Hungary

It is crucial to understand the role that labor market positions might play in creating gender differences in work–life balance. One theoretical approach to understanding this relationship is the spillover theory. The spillover theory argues that an individual’s life domains are integrated; meaning that well-being can be transmitted between life domains. Based on data collected in Hungary in 2014, this paper shows that work-to-family spillover does not affect both genders the same way. The effect of work on family life tends to be more negative for women than for men. Two explanations have been formulated in order to understand this gender inequality. According to the findings of the analysis, gender is conditionally independent of spillover if financial status and flexibility of work are also incorporated into the analysis. This means that the relative disadvantage for women in terms of spillover can be attributed to their lower financial status and their relatively low access to flexible jobs. In other words, the gender inequalities in work-to-family spillover are deeply affected by individual labor market positions. The observation of the labor market’s effect on work–life balance is especially important in Hungary since Hungary has one of the least flexible labor arrangements in Europe. A marginal log-linear model, which is a method for categorical multivariate analysis, has been applied in this analysis.

LIBRARY: A DEFINITION FROM ANOTHER CONTEXT

This essay presents a series of discussions revolving around the discipline of library professionals who are trained in it.It covers the concept of Library from the formal point of view, contributed by some authors and dictionaries, but also from the particular vision of the author, who conceptualized from the working level, academy, research and daily contact with users.Therefore, it is a short journey from the traditional to the current reality with the inclusion of information technology and communication. But above all, a journey of a very personal feel.

The image of the Hungarian and UK building industries : a comparative analysis

Concern that poor image of UK construction industry is restricting recruitment has lead to call for action. This paper gives the results of a recent comparative analysis of the image of both UK and Hungarian industries which indicates the UK image to be relatively good. The perceived cause of Hungarian problems is the poor level of organisation and management.

Building and Using Existing Hunspell Dictionaries and TEX Hyphenators as Finite-State Automata

There are numerous formats for writing spellcheckers for open-source systems and there are many descriptions for languages written in these formats. Similarly, for word hyphenation by computer there are TEX rules for many languages. In this paper we demonstrate a method for converting these spell-checking lexicons and hyphenation rule sets into finite-state automata, and present a new finite-state based system for writer’s tools used in current open-source software such as Firefox, OpenOffice.org and enchant via the spell-checking library voikko.
