This article presents the physical structure of the land, organic substances content and the chemical composition of soil comprising subsoil of 21 urban greenery locations in the city of Poznań. As they tend to be commonly underestimated, they have also been presented with view to their vital functions in plants’ life processes. The analysed microelements are referred to their levels, the so-called geo-chemical background of Polish soils and the limit values for field soils with medium levels of nutrients.

Dependence of severe storm occurrence on circulation types in Poland

The paper investigates the relationships between the occurrence of thunderstorms with heavy precipitation (> 30 mm) and atmospheric circulation types. The study covers the period 1951–1998 and is based on a matching span of records of thunderstorm occurrence and daily precipitation totals at 47 weather stations in Poland. A catalogue of circulation types by Osuchowska-Klein, data on frequency of fronts over south-eastern Poland by Niedźwiedź and weather maps were used. In Poland, days with a thunderstorm and more than 30 mm of precipitation are extremely rare and occur mainly in summer. Their recurrence period amounts to about two to four years, with the exception of mountain areas (southern Poland) where they occur nearly every year. The heaviest precipitation on a day with thunderstorm, 166.1 mm, was recorded at a high-mountain station on Mt. Kasprowy Wierch. Apart from this station the highest precipitation was 141.0 mm and only eight stations had at least one record of more than 100 mm. Four regions characterised by different circulation types most favourable for the occurrence of thunderstorms with heavy precipitation were identified. In all of them southerly advection was most favourable for the occurrence of the phenomena studied (Sc, SEc, Sa/c), but that effect was especially prominent in the south-western region. Most of the days with thunderstorm and heavy precipitation coincided with the passing of an atmospheric front over Poland (53.8–81.9% days depending on the station). Days with air-mass thunderstorm and heavy precipitation were rare and mostly occurred in areas of variable topography.

Geomorfologiczne uwarunkowania rozwoju sieci komunikacyjnej na obszarze młodoglacjalnym (zlewnia Perznicy, Pojezierze Drawskie

The aim of the studies in the Perznica River catchment were relief changes caused by the development of transportation infrastructure. This type of transformation is dependable on the state of economy and the settlements. The development of transportation network in the last two hundred years was examined through the analysis of archival cartographic materials – maps from the years 1789, 1855, 1877, 1935 – and the comparison with the situation from mid 1980s. The Perznica River catchment has an area of 249 km2 and it is located in north-western Poland in the central part of the Drawskie Lakeland macroregion, which belongs to the West Pomeranian Lakeland. The heterogeneous Perznica River catchment relief has a denivelation of 159 m and is within 60 and 219 m a.s.l. The study area is within the Parsęta River lobe. A number of subzones, whose morphological diversity and diversity of sediments lithofacies is mainly a reflection of areal deglaciation of the continental ice-sheet marginal zone, has been distinguished and these are: • subzone of the internal kame moraine – the undulated moraine upland, diversified by kame forms and kettle holes, • subzone of ice-free space forms – the uplands of kame plateaux, • subzone of melt-out lake basins – Lake Wielatowo basin with a characteristic collar ridge, • morphological levels of the northern Pomeranian sloping surface – mainly flat moraine uplands and small outwashes. The economic development of the Perznica River catchment advanced in close connection with the physical and geographical context, mainly with the relief, soils and hydrological conditions. As a result, the flat moraine uplands and marginal outflow plains, which were easiest to cultivate, have been developed and populated faster than any other. Since the early medieval period, large, compact villages, often centered around big estates, were emerging in those areas. In areas with a high relief energy–kame-melt moraines, ice-free space forms and ridges around melt-out lake basins–farming entered on a larger scale from the eighteenth century. Scattered settlements in those areas forced the creation of a dense access road network to farms and fields. In the case of anthropogenic forms of transportation with denivelation exceeding 1 m in the study area, road excavations are present for 37.3 km, road undercuttings for 43.8 km and road embankments for 38.7 km in total length. That gives a high ratio of density of such forms, equal to 2.1 km per km–2.

This article is the first one in the series of four publications describing the condition of soil environment in the area of broadly understood centre of Poznań. The paper presents the results of studies into a ph ph ph ysical structure of the soil collected around horse chestnuts (Aesculus hippocastanum), growing in various habitats in 21 locations in the area of Poznań. In the majority of cases, 75 per cent of them, the obtained data point to a deficient ph ph ysical structure of subsoils. Only in five cases, out of a general number of 21 locations, the roots of the trees developed in soil conditions that were favourable for the plants, and which enabled them the retention of precipitation water, oxygention of rhizosph ph ere and accumulation of humus.

Strong High Pressure Systems Influencing the Weather in Poland During the Period 1971-2000

This paper shows preliminary results of research into the occurrence of strong anticyclonic systems that influenced the weather in Poland during the period 1971–2000. The study was based on NCEP/NCAR reanalysis data, including daily values of the 1000 and 500 hPa geopotential heights, maps of mentioned geopotential heights and maps of sea-level field pressure. With the use of these data a number of exceptionally strong high-pressure systems were identified, together with their areas of origin and subsequent development patterns. They were then broken down into five groups with similar dynamics. The numbers of systems in each group were not found to follow any significant change trends in the long term. The greatest differences between groups were identified in terms of their annual occurrence rates and centre pressure values.

Modelos de desarrollo, unificación y “desterritorialización”.

El presente estudio tiene el objetivo de ofrecer una visión general sobre los Modelos de Desarrollo y Organización Territorial desde la perspectiva de las relaciones entre el medio urbano, “rururbano” y rural, en España. Para ello, tras conocer y valorar los enfoque conceptuales y temáticos, se estudia el crecimiento urbano en nuestro país en las últimas décadas, analizando de manera pormenorizada la importancia que ha cobrado y cobra la aplicación legislativa de leyes, planes y normas, tanto en el propio crecimiento urbano como en la demanda de viviendas en las ciudades españolas y, de igual modo, la vinculación de ambas con el precio de las viviendas, relacionándolo con la problemática de la “rururbanización”, y del medio rural.

The consequences of child-parent violence reflected in a life story

A process of social transformation allied with ongoing changes to the family has made possible the existence of a relatively little-known phenomenon: that of child-parent violence, which is raised as one of the most commonly experienced forms of violence in the family environment. Based on the study of this phenomenon, in our research we have used the qualitative technique of a life story, making use of a field diary in which we have taken notes on our daily work in the therapeutic context, for the purposes of mitigating the effects of such a process. The following research objectives were set: establishing the connection existing between family education style and the use of violence by the minor; and evaluating the extent to which family therapy mitigates the use of violence by the minor. The family education model, together with other dimensions, results in situations of child-parent violence occurring repeatedly, with continuing negative reinforcement from both parties in order to maintain a recurrent cycle of conduct, from which it is difficult to «escape» other than through a process of ongoing psychological therapy.

Scientifi c discourses on chronic pain without organic cause Incorporating gender perspective for pain resignifyng-repoliticizing

Chronic pain, without any organic or physical cause (DC), which in psycho-medical terminology is known as fi bromyalgia, (FM), is diagnosed each year to a considerable number of women in capitalistic societies. Our main interest in the following paper is to go in depth in the elaboration of this symptom, its treatment and the psychosocial effects, both in the social order as well as in the lives of the people who suffer from it. Our main goal in the following paper is to look deeper in the elaboration (conceptualization) of this symptom, its treatment and psychological affects, both in the social order as well as in the lives of the people who suffer from it, we are using linked speeches in Spanish magazines publications. The result has been the emergence of three hegemonic discourse positions: One position “scientist”, one “therapeutic of the conformity” position and one “economic and legalistic” position. Each of these has a specifi c feature, but on the whole, is enhanced, producing effects such as the absence of social context to explain the disease; disregard of gender differences in the management and treatment; the instrumentalization of pain to legitimize their practices and the subjection of women to the “psycho-biomedical” paradigm. In that way, a new signifi cance and politicization of the concept of pain is proposed.

Bolsa Familia Program and school enrolment: An analysis of the 2010 Brazilian demographic census

The Bolsa Família Program goal is to promote social development and poverty reduction, through the direct transfer of conditional cash, in association with other social programs. This study aims to analyze whether Bolsa Família had an association with children’s school attendance, which is one of the educational conditions of the program. Our main hypothesis is that children living in households receiving Bolsa Família had greater chances of attending school. Data from the Ministry of Social Development and Combating Famine indicated that children living in households with Bolsa Família had greater school enrolment levels. By using data from the 2010 Demographic Census, collected by the Brazilian Institute of Geography and Statistics (IBGE), some descriptive analyzes and binary logistic regression models were performed for different thresholds of household per capita income. These estimates were made by comparing children who lived in households receiving Bolsa Família to those children not receiving the program. We took into consideration characteristics about the household, mothers, and children. The results were clustered by the municipality of residence of the child. In all income thresholds, children benefi ting from Bolsa Família were more likely to be enrolled in school, compared to children not receiving the benefi t.

Alien gosd in the new epics: Noah remythologised through the ancient astronaut hypothesis in Abel's Montagut's "La gesta d'Utnoa"

Modern scientific world-view has undermined traditional myths, the functional survival of which seems to depend today in the West on a positivist justification. This would place them in the field of real History, through their study and revitalization by pseudoscientific disciplines such as the Atlantis and the ancient astronaut hypotheses. These have inspired new epic poems in (regular) verse that combine classic and/or biblical myths with a (pseudo)scientific modern world-view. For example, the critical rewriting of Noah’s myth by using the ancient astronaut hypothesis as a fictional device to produce a contemporary kind of plausibility allowed Abel Montagut to renew epic poetry, updating it also by adopting science fiction chronotopes in order to structure his fictional construction and to generate a high ethical sense for our time. Thus, his Poemo de Utnoa (1993) / La gesta d’Utnoa (1996), which has become a major classic of the literature in Esperanto thanks to its original version in this language, is a landmark of both science fiction and neo-biblical epics. This poem is written from a secular and purely literary perspective.

Las Comisiones del Mapa de España en la década de 1850

La necesidad de contar con un mapa de base científica que cubriera todo el territorio español llevó al Estado a crear en paralelo varias Comisiones con cometidos geodésicos, topográficos y cartográficos durante la década de 1850. La labor simultánea de estas Comisiones se prolongó hasta 1859, cuando se aprobó la Ley de Medición del Territorio, que las fusionó en un único organismo. Este artículo analiza aspectos técnicos de los trabajos que realizaron estas Comisiones a partir de la información contenida en algunos documentos que custodia el Archivo Topográfico del IGN. Las conclusiones que se extraen son que estas Comisiones acometieron operaciones geodésicas que resultaron cruciales en el establecimiento ulterior de la red de triangulación peninsular, realizaron mediciones topográficas que fueron reutilizadas veinte años después en el levantamiento del Mapa Topográfico Nacional, e idearon las características catastrales que fueron adoptadas durante todo el siglo posterior para el Catastro de España.

O ESTUDO ACADÉMICO DO TURISMO CULTURAL

O turismo cultural tem múltiplas facetas e varia entre as diferentes regiões geográficas. Hoje, os turistas culturais desejam conhecer e compreender os lugares que visitam, particularmente, o património material e imaterial de uma região ou país. O desenvolvimento do turismo cultural tem atraído a atenção de vários investigadores, especialmente, do campo da Sociologia, da Antropologia, da Geografia e do Turismo que procuram analisá-lo na vertente da oferta e da procura. Por outro lado, tem existido muito debate académico sobre o que realmente é o turismo cultural e quem são os turistas culturais. Uma das complexidades em definir o turismo cultural está na diversidade da cultura que os turistas consomem. Palavras-

Desenvolvimento local: estratégias e competitividade

O tema desta tese relaciona-se com a qualificação das estratégias de desenvolvimento municipais. A emergência do planeamento territorial estratégico, como alternativa ou suplemento ao planeamento físico tradicional, reintroduziu o debate sobre a capacidade de o planeamento territorial influenciar trajectórias de desenvolvimento descentralizadas. A investigação segue, em termos teóricos e empíricos, duas linhas de inquirição: uma, relativa aos desafios colocados pelas premissas metodológicas e operativas da abordagem estratégica em planeamento territorial; a outra, diz respeito às implicações da actualização da agenda que acompanharam a emergência da abordagem estratégica, incidindo designadamente sobre a questão da competitividade territorial. A primeira lida com a validade intrínseca da abordagem estratégica e a forma como esta confronta as práticas tradicionais dominantes no planeamento territorial, em particular em Portugal. É feita uma análise do debate e dos resultados de experiências recentes em planeamento territorial estratégico e uma reflexão sobre a forma como estas podem influenciar o estabelecimento de novos referenciais para a intervenção dos sistemas de planeamento. A segunda pretende aprofundar o conhecimento sobre as competências necessárias ao planeamento, para a gestão de processos descentralizados de promoção da competitividade, e avaliar o alcance dos resultados obtidos até agora e as limitações associadas à concretização daquele objectivo. Argumenta-se que algumas das mais significativas exigências conceptuais da perspectiva estratégica de intervenção sobre o território são tratadas com ligeireza, ao mesmo tempo que, no contexto da definição de um quadro de avaliação do planeamento territorial estratégico, se espera contribuir para uma reavaliação do papel que cabe ao plano, enquanto instrumento de referência e de motivação para a acção em planeamento. Na outra parte da investigação, relativa à actualização da agenda de planeamento, é feita uma análise crítica da noção de competitividade Territorial. Usando contributos disciplinares da economia regional, da geografia económica, da sociologia económica e dos sistemas territoriais de inovação desenvolve-se um quadro conceptual que procura pôr em evidência a convergência entre as capacidades de uma prática qualificada de planeamento territorial estratégico e as necessidades e requisitos dos processos de desenvolvimento local. A análise de um conjunto de experiências municipais de concepção e implementação de planos estratégicos, representando realidades locais bastante heterogéneas em termos de dinâmica económica e de capacidades institucionais, é usada para avaliar alguns dos principais aspectos levantados em cada uma das linhas sob investigação.
