This study investigates the influence of atmospheric circulation in the Mediterranean region on the precipitation in Montenegro. Nine precipitation parameters have been used in the analysis and the relationship has been investigated by the Mediterranean and West Mediterranean Oscillation change index (MO and WeMO). According to a 60 - year observed period (1951-2010), the research results show that nothing characteristic happens with seasonal and annual precipitation sums because the trend is mainly insignificant. However, precipitation extremes are getting more extreme, which corresponds with a general idea of global warming. Negative consequences of daily intensity increase and frequency of precipitation days above fixed and percentile thresholds have been recorded recently in the form of torrents, floods, intensive erosive processes, etc., but it should be pointed out that human factor is partly a cause of such events. The estimate of the influence of teleconnection patterns primarily related to the Mediterranean Basin has shown that their variability affects the observed precipitation parameters on the territory of Montenegro regarding both seasonal and annual sums and frequency and intensity of extreme events shown by climate indices.

This article is based on letters from the Geniza. The writers were merchants who dealt in imports and exports between Egypt and other countries of the Mediterranean basin. These merchants were part of the Jewish elite and maintained close ties with the Muslim authorities. They enjoyed considerable status with these authorities, who co-operated with the merchants, especially in the transport of goods; some of the high officials were, in fact, ship-owners. The administration of the time took a great interest in imports and exports, and would at times confiscate goods required by the army. The article reviews a series of citations from letters thus examining the relationship between the merchants and the authorities. The second part deals with the evidence of the droughts found in the merchants' letters; it is interesting to compare the details on droughts with the information in the Arabic sources. The third part discusses the information contained in the Geniza documents on the conquest of Jerusalem (638). This is followed by a discussion of two figures who are also known from Arabic sources: Manasseh b. Abraham Ibn al-Qazza¯z, and Barjawa¯n. The letters also reflect the restrictive measures against Jews and Christians in the days of Caliph al-Ha¯kim.

Abstract. In the frame of MEDSCOPE project, which mainly aims at improving predictability on seasonal timescales over the Mediterranean area, a seasonal forecast empirical model making use of new predictors based on a collection of targeted sensitivity experiments is being developed. Here, a first version of the model is presented. This version is based on multiple linear regression, using global climate indices (mainly global teleconnection patterns and indices based on sea surface temperatures, as well as sea-ice and snow cover) as predictors. The model is implemented in a way that allows easy modifications to include new information from other predictors that will come as result of the ongoing sensitivity experiments within the project. Given the big extension of the region under study, its high complexity (both in terms of orography and land-sea distribution) and its location, different sub regions are affected by different drivers at different times. The empirical model makes use of different sets of predictors for every season and every sub region. Starting from a collection of 25 global climate indices, a few predictors are selected for every season and every sub region, checking linear correlation between predictands (temperature and precipitation) and global indices up to one year in advance and using moving averages from two to six months. Special attention has also been payed to the selection of predictors in order to guaranty smooth transitions between neighbor sub regions and consecutive seasons. The model runs a three-month forecast every month with a one-month lead time.

Introduction. In recent decades, the problem of the formation of a holistic perception in students’ minds of the surrounding reality in the field of education has become acute. The buildup of scientific knowledge, which is a determinant of the structure of the content of education, occurs impetuously. Students’ thinking and consciousness become fragmented due to the exorbitant, permanently increasing amount of information that is presented for learning, but cannot be fully mastered by students. The root cause is imbalance in the curriculum levels of integration and differentiation (with a roll in the direction of the latter). To compensate the current imbalance and reverse the dangerous situation that threatens society with extremely negative consequences, an audit of the structure of educational content and the search for its new conceptual models are required.The aim of the publication was to show the importance of using the phenomenon of symmetry in the construction of structures of scientific knowledge and the content of education.Methodology and research methods. The study was based on the ideology of F. Klein “Erlangen programme”; E. Wigner’s scheme, showing the division of areas of scientific knowledge; generalised idea of symmetry by G. Weyl; the personal-activity approach to structuring the content of education, improved by V. S. Lednev; and also on the theoretical and methodological analysis of other scientific sources related to the topic under discussion.Results and scientific novelty. The general idea of symmetry, borrowed from geometry, but nonetheless having a general methodological rather than a particular character, is proposed as the basis for systematising sections of scientific knowledge and structuring foundation of the content of modern education. The ability of symmetry to combine the merits of the primary deductive concept and the general inductive concept reflects the tremendous work performed by mankind in the course of history to identify stable patterns, sets of invariants (the allocation of which is the basic condition for the development of intelligence) and the corresponding forms of symmetry. That is, the forms of generalised symmetry accumulate in a compact form all the available knowledge and serve as a tool developed by society for systematising the phenomena and laws of the surrounding reality. The examples convincingly demonstrated the integrative property of forms of symmetry, manifested in the relationship between its principles, the laws of nature and natural phenomena. The principles of symmetry set the structure to areas of the laws of nature and natural phenomena, which, in turn, in the form of cross-cutting lines (according to V. S. Lednev) can determine the content of education. In addition, it justifies the expediency of introducing a special cross-cutting Symmetry line, consisting of a course system – apical elements, supplemented by implicit elements scattered in courses of other cross-cutting lines. Such an approach will eliminate the narrow specialisation in the learning process and avoid fragmentary perception of educational information and the surrounding reality. Practical significance. The research materials presented in the publication can be useful both for scholars and educators, who study the content of education, as well as for practitioners involved in the selection of educational material in the development of educational programmes at various levels.

This work is about a note which records some results concerning a research undertaken in Algeria. It is part of a cooperation between several Mediterranean teams. Its objective is to report on current developments in agricultural practices on the environment and on the territories, in order to design conceptual scenarios that will draw profiles that can ensure sustainable food security in cities and the maintenance of biodiversity. Similarly, it will have another interest, it is to develop an exhaustive and homogeneous database on the western part of the Mediterranean basin. For Algeria, the studied areas are distributed on a biogeographical section, from the Mediterranean coast to the Sahara, that is to say, places sufficiently representative of the North-South ecological degradation and of the diversity of situations. The results reported in this note concern two Saharan areas, the Ziban and the Souf, as the final results of the research have not yet been achieved, since the project is still ongoing. In these two areas, agriculture in the past was limited to the traditional oasis system, just to ensure the subsistence of the inhabitants, but today, several factors have contributed to a revival of agriculture whose development is spectacular. Thus, the Ziban and the Souf have become very important food producing areas and even exporters of food products. However, it should be pointed out that this dynamic, if it is a source of innovation, it has negative consequences on the oasis heritage and on the environment.

The food and water challenges to be faced in the Mediterranean Basin, particularly those on the southern and eastern shores, are daunting. They form a complex nexus of problems and require policies pursuing several important potentially conflicting goals at the same time: reducing or limiting food import dependency through increased agricultural production in environmentally sustainable ways while protecting the natural resource base and keeping food affordable for poorer populations. The worrisome trends affecting countries on the southern and eastern shores of the common sea can also have seriously negative consequences in the North which explains why the North-South collaboration has a long tradition in the region. But, as the case of water management institutions shows, ineffective advocacy for trade liberalization has led to conflicts and tensions on various issues and has distracted attention from potentially much more fruitful areas of collaboration.

Abstract. The Most Expected Rainfall Regime – MERR in a certain region is composed of various parameters regarding the annual rainfall regime in that region. The present study examines several parameters of the MERR, such as: the rainfall TOTAL, the Date of Accumulated Percentage-DAP, the Rainy Season Length-RSL, the Number of Rain-Spells-NRS, the Rain-Spell Yield-RSY, the ratio between Average and Median rainfall-AMED, the relationship between accumulated precipitation and the number of rain-spells and the Dry-Spell Distribution-DSD. Two stations at the two sides of the Mediterranean basin, Valencia and Larnaca, have been used to illustrate the distribution of the above parameters across the Mediterranean. The main conclusion of the study is that the rainfall regime at Larnaca is less uncertain as compared with the regime in Valencia. This is probably due to the fact that rainfalls are completely absent during the summer in Larnaca, which better suits the definition of a Mediterranean climate than that of Valencia.

This chapter discusses the extent to which communities in temperate Europe became increasingly integrated into the larger world of the Mediterranean basin and beyond, and how the process of integration worked. Major changes in the visual structure and patterning of objects took place in the context of major changes in the relationship between societies in temperate Europe and societies in the Mediterranean basin, in Asia, and in Africa. The changes emerged internally, from within the societies of temperate Europe. They were in no sense “caused by” outside societies, nor by trade relations with outside societies. The changes in the visual character of fifth-century-BC objects resulted principally from the expanded dissemination of ideas, embodied in new objects, styles, motifs, and designs. The changes in the second century BC resulted mainly from the expansion of commerce—of trade in goods.

Abstract. This brief communication introduces a new quality-controlled precipitation database for Calabria, shows the precipitation trend for the period considered, and correlates daily rainfall with some common teleconnection patterns. The database consists of daily accumulated precipitation collected by 61 rain gauges from 1 January 1970 to 31 December 2006. The 37-year trend in yearly rainfall shows a decrease of 4.7 mm/y, with a 17% reduction in the yearly mean value. The correlation of the daily rainfall with large-scale patterns shows that the Mediterranean Oscillation Index (MOI a/c) is a useful predictor of daily precipitation over Calabria.

The authors explore an alternative way of analyzing the relationship between human development and individualism. The method is based on the first principal component of Hofstede's individualism index in the Human Development Index rating domain. Results suggest that the general idea that greater wealth brings more individualism is only true for countries with high levels of development, while for middle or low levels of development the inverse is true.
