A short survey of normative properties of possibility distributions

In 2001 Carlsson and Full´er [1] introduced the possibilistic mean value, variance and covariance of fuzzy numbers. In 2003 Full´er and Majlender [4] introduced the notations of crisp weighted possibilistic mean value, variance and covariance of fuzzy numbers, which are consistent with the extension principle. In 2003 Carlsson, Full´er and Majlender [2] proved the possibilisticCauc hy-Schwartz inequality. Drawing heavily on [1, 2, 3, 4, 5] we will summarize some normative properties of possibility distributions

Development tools for mobile devices in market price information systems

There are already several applications on mobile devices that can be useful in agriculture. For example: GPS-enabled map software, individual cattle identification and tracking software and even complex agricultural systems. These are just beginning to spread in the Hungarian agrifood sector. The possibility of using for agribusiness of mobile internet and mobile tools is increasing. Mobile tools are really suitable for tasks like inspecting the evolution of prices of agricultural products. One of our application development is a mobile extension to access the Market Price Information System run by the Hungarian Agricultural Economics Research Institute. The accessibility of information demanded by market actors can be ensured effectively by using mobile tools. The biggest limitation for PDA is screen size. If it is getting smaller from full screen to PDA-sized and yet further to mobile phone dimensions, user performance drops. The main reason for this is that smaller screens make it more difficult for a user to make good judgements about the usefulness of any particular information. The development methods and tools help us to solve one part of these problems

A pure probabilistic interpretation of possibilistic expected value, variance, covariance and correlation

In this work we shall give a pure probabilistic interpretation of possibilistic expected value, variance, covariance and correlation

Comparison of Moodle and ATutor LMSs

E-learning is a technology that plays an important role in modern education and training. Its great importance lies in the fact that it makes learning content readily available at any place at any time. This paper examines and evaluates two of current systems Moodle and ATutor. The main aim of this paper is to identify the aspects of theese LMS systems, examine their functional features, modules, standards, hardware and software requirements, and compare them

Hermetizmus, exaltatio és szabadkőművesség

The purpose of this paper is twofold. One goal is to investigate how the hermetic tradition of the 17thcentury Scottish-English lodges lived on in the ritual practice of English freemasonry in the age of Enlightenment. Accordingly, it highlights some parallels and dissimilarities between the hermetic and masonic traditions. A second objective is to examine whether the doctrine of exaltatio — referring to the programme of deification recognized by György E. Szőnyi in the writings of henneticists such as Pico della Mirandola — can be traced in masonic rites of passages. The findings partially rely on the analysis of some hitherto overlooked 1e-century masonic ceremonies, including the earliest known ritual of the Royal Arch

The role of demographic and socio-economic characteristics in affecting subjective well-being: the case of Hungary

The paper investigates the influence of various demographic and social factors on the perception of well-being in Hungary. For the purpose of the analysis, various measures of subjective well-being have been developed, as dependent variables, using both narrower and broader set of items, and principal factor analysis was applied to construct normalised indices. Demographic predictors include gender, age, family composition, residence; sociological predictors contain education, labour market position, income and wealth as well as questions on health and religiosity. Hungary is an interesting case to study, given the well-known strong deficit in subjective well-being. The phenomenon is particularly motivating in the light of the official propaganda by the governing political forces on the country’s economic and social progress. Low level of subjective well-being is confirmed again, partly in international comparison, partly from the perspective of temporal change. Furthermore, detailed analysis of the data reveals that Hungarians seem to be markedly divided by age, residence and social status for higher or lower assessment of well-being. Regression models prove that material conditions have the strongest impact on subjective well-being, even if controlled for education and labour market position. The results on subjective-wellbeing raise questions for public policy in Hungary
