In this article, data bases from the 1989 and 1999 Agricultural Censuses are employed in order to elaborate a typology of the bovine farms in Galicia, which is based on the farms economic and demographic viability. The analysis allows us to conclude that the sector is integrated by three large groups of farms, with very different characteristics and perspectives. The first group is made of farms with economic and demographic viability, representing only 1/5 of the total although concentrating most of the output, whereas the second contains 1/3 of the total number of farms which are operated by farmers aged 55 or above without successor, and in its majority of very small size. Finally, the third is the most numerous group (50% of the total) and formed by farms with a more uncertain future, because they have possibility of succession but are not economically viable. Thus, the obtained results are used in three ways: to offer an analysis of the present structure of the sector, to interpret its recent transformations, and to project the tendencies for the next decade (1999-2009).

Professionals who work in the social and physical sciences and who have a serious commitment to the Bible have, in a sense, two data bases. To integrate them is a difficult task. We are pressed to bring them both into focus by the holistic thrust of the Bible as well as by the penchant of our minds to synthesize. To do this effectively we need simple but not simplistic models. Our integration must further be comprehensive, not partial, basic, not peripheral. This article describes a method of doing this kind of integrative work. Initially, four fundamental criteria are presented. In the second section the basic methodology is worked out, and in the third, some primary themes are described and illustrated around which this particular integrative system works.

Three rockets carrying radio propagation experiments were launched respectively into the prebreakup, breakup, and postbreakup phases of auroral displays during early 1968. The radio measurements, which provide information concerning the three-dimensional spatial gradients in ionization, show quite different characteristics for the three occasions. In the first two it seems that the configuration of ionization was essentially similar to that of the visible aurora. In the third, during a widespread homogeneous auroral glow, the ionization showed weak small-scale irregularities, possibly generated locally by plasma instabilities. Data from a ground-based photometer and from particle precipitation experiments aboard two of the rockets are also compared with the radio evidence.

Data bases play an important role in applied Mathematics. Normalization for relational databases is very important to avoid anomalies of relations which may not be in normalized forms of the third normal forms. But, normalization may be a difficult task, since the designers of the databases may not fully understand the domain of each attribute that are contained in the relation schema or they may not have full understanding about the concept of normalization. In this paper an efficient method that checks the possibility of the need of further normalization using stored data in relations is presented based on possible functional dependencies between attributes in the relations. By checking possible functional dependencies, the database designers can determine the need of further normalization, and may improve the structure of the relation schemas. Experiments were performed for an example of relational database that can be found in the organization of tutorial of MySQL which is a representational database management system, and the experiments showed good results.

Human personality depicts an individual’s behavior and it is a formal object of psychology. Understanding human behavior is a vital and fundamental subject to understand human’s essence. The typology of behavioral concept is multifaceted and varied. In fact, various definitions of personality arrive at a single substance. This paper analyses Sigmund Freud’s concept on personality through the eye of Qur’an. The Qur’an made a personality concept as part of its focus. Through a comparative method, this study concludes that both Freud and the Qur’an argue that human personality consists of three components or potentials with different characteristics, yet integrated, to create human behavior and its personality. Freud calls them consecutively as Id, Ego and Superego; while the Quran calls them as Nafs, Akal and Kalbu. The difference between Freud and Quran on personality concept lies on the source where these three potentials came from. In Freud’s view, they came from the human being themselves internally or being influenced by their surroundings. Freud did not count God’s influence in his theory. According to Quran, however, the third potentials (Kalbu)depicts God’s values embedded in human being. Kalbu is called as a God’s disposition (tendency). Thus, Quranic concept on personality is theocentric while Freud’s is anthropocentric which is much dependent on rationality and morality of human being.

This is the third of a series of three articles, based on the lecture we delivered at the International Workshop ‘Studies of Large Groups and Social Unconscious’, which took place in Belgrade in June 2013. In the first part we compared the British and the Latin American traditions of group analysis. In the second, we discussed the conception of the social unconscious and the group analytic large group, in both traditions. Now we present our own approach to large groups and discuss the problem of the wider context in which the large group takes place.

AbstractAfter the initial enthusiasm in the homeopathic community about the exciting progress and expansion since the 1980s, the sobering fact seems to be that we evolved in the direction of such sophistication that our dear system becomes unmanageable. We did our inner work, try to balance things that were somehow off but still the plain fact is that we are still crushed under too much information. And there is no way to stop it! We are only at the beginning of exploring and including every single species on the planet and beyond in our Materia Medica. But we've already come to a point where even the fastest and most extensive software programs won't help us solve a case. In this article, I argue that we need to boil down the overwhelming bulk of data to clear, simple and reliable pointers to large groups and then smaller groups. The best way to do this is adding the ‘context’ in the analysis. Though often overlooked it turns out to be solid information. The first distinction in a case analysis could be between the Second Dimension (Rocks and Stones, Gems, Bacteria, Viruses, Sarcodes) and the Third Dimension groups (Plants, Animal and Fungi) and often the context will decide. Some information on these groups is given, in an attempt to make homeopathy manageable again without losing its refinement.

The main aim of the present study was to explore the significance of large group/greater pen housing (PH) versus standard Makrolon caging (ST) in three behaviour tests related to human-animal interactions in the adult male laboratory rat. The rats' perception of human interaction was tested in three behavioural tests, of which two reflected common practical procedures, capture and restraint, whereas the third was a human approach test in a Y-maze. The rats' anticipatory reactions to handling and the reactions to restraint did not differ between groups, but the ST rats approached a human hand more quickly than did the PH rats ( P < 0.01). Although food intake did not differ, ST rats gained more weight ( P < 0.01) and had higher total cholesterol values ( P < 0.01) than PH rats. In conclusion, this study shows that housing rats in large groups in an enriched environment did not influence their anticipatory reaction to handling in normal handling situations. However, as the PH rats tended to have a longer approach latency than ST rats in the Y-maze there might be underlying differences in appraisal that are not detected in practical situations. In addition, the PH rats weighed less and had lower total cholesterol values than ST rats and their urine corticosterone values were higher. These effects are suggested to be due to higher physical activity in the PH rats, and the implications of this on the animal as a model is discussed.

We present an algorithm for deconvolving a seismic trace by extracting spikes one at a time, thereby obtaining a sparsely populated spike train. Three versions of this algorithm are then compared empirically, by applying them to several examples of synthetic and real seismic data. The first two versions correspond to the use of the [Formula: see text] (least‐absolute‐values) and [Formula: see text] (least‐squares) norms, while the third is a faster and more compact version of the [Formula: see text], algorithm. The [Formula: see text] procedures are shown to exhibit different characteristics which are often desirable, and the results are generally superior to those of the [Formula: see text] procedure for one‐at‐a‐time spike extraction. The use of the fast [Formula: see text] algorithm is advocated in practice for efficient and effective deconvolution.

The purpose of the article was to indicate selected distribution channels in groups and organizations of fruit and vegetable producers in countries with different agrarian structures and cultures of horizontal organization, as well as identify differences in preferred distribution channels. Based on the literature review, changes in the supply chain of agri-food products were presented and the growing importance of retail chains was pointed out. Using the data obtained from the European Commission, the weight of individual distribution channels was presented, and by Ward agglomeration cluster analysis using Euclidean distances, 3 disjointed clusters of countries with different characteristics of fruit and vegetable producer groups/organizations were selected. The first cluster consisted of few producer groups/organizations from Great Britain, Denmark and Romania, whose members engaged in a relatively large area of land and dedicated (65%) their production to retail chains, thus obtaining, on average, higher effects (measured by sales value) attributable to both the group/organization and hectare of land. In contrast, the third cluster included producers from countries that are leaders in the production of fruit and vegetables in Europe, that is, from Spain, Italy, France and Poland. What was characteristic for them was that many members possessing a relatively small area of land joined groups/organisations. They dedicated their production (25%) to retail chains, and their advantage, which may affect the largest share of the average value of sales per member, is the processing of raw materials as part of their own operations.
