The aim of this article is to analyse the novel "Na die geliefde land" (1972) by Karel Schoeman, by interpreting the function of 'hulle' ('they') as a category of alienation/distancing. Schoeman presented a future vision of South Africa controlled by an unidentified group of 'them' and showed Afrikaners as a marginalized group, forced to live on farms. A narrow political interpretation dominated in the reception of this book, which was treated as a simulation of the development of the political situation in South Africa. The key argument of this article is that the indeterminate representation of the situation after the revolution is not a weakness of this novel, but a conscious strategy of the author. The article argues that problems concerning political revolution ('Who', 'Why', 'When') are not that relevant in a reading of the novel because "Na die geliefde land" deals mainly with an Afrikaner community’s reactions to a changed situation.

Wśród niematerialnych potrzeb ludzkich do najważniejszych, z punktu widzenia polityki społecznej, należy potrzeba bezpieczeństwa. Stąd takim istotnym problemem jest gwarantowanie obywatelom poczucia bezpieczeństwa socjalnego. Choć z jednej strony, rozwój gospodarczy przynosi za sobą wzrost zamożności społeczeństwa, a co za tym idzie, wzrost poczucia bezpieczeństwa socjalnego, z drugiej strony w społeczeństwie nadal występują osoby i grupy, które, z różnych powodów, nie korzystają z owoców owego postępu. Dotyczy to zwłaszcza tych, którzy maja ograniczony dostęp do podstawowych dóbr i usług powszechnie przysługujących. Ta kategoria osób – to osoby wykluczone, czy też marginalizowane społecznie. Dla wykluczenia społecznego najbardziej charakterystyczne są trzy cechy: niski poziom uczestnictwa w życiu społecznym, długotrwałość i niedobrowolność takiej sytuacji, ograniczenie możliwości korzystania z podstawowych praw obywatelskich. Kwestia wykluczenia społecznego od niedawna została uznana przez Unię Europejską za jeden z podstawowych problemów społecznych. Stąd ogłoszenie roku 2010 Europejskim Rokiem Walki z Ubóstwem i Wykluczeniem Społecznym i podjęcie konkretnych działań w celu ograniczenia tych zjawisk. Daje to nadzieję, że tak w Unii Europejskiej, jak i w Polsce uda się zmniejszyć ilościowe rozmiary wykluczenia społecznego.

After the 1980s it is diffi cult, following stylistic criteria, to draw a map of contemporary academic music. All styles are compossible, and all are practiced. In this context, the geographical entity “South of Italy” does not stand out for a musical identity with special technical-stylistic features. Rather, at a socio-cultural level, the South remains today – in music no less than in all areas where there is a gap between top development and stagnation – a land of emigrants: six out of the seven composers treated (Ivan Fedele, Giuseppe Colardo, Rosario Mirigliano, Giuseppe Soccio, Nicola Cisternino, Biagio Putignano, Paolo Aralla) live in the North of Italy. The positive aspect of this is the affi nity of the South with the transnational and superstructural community of contemporary music, which from European and Western has now become almost global. The composers under consideration belong to the generation of the ‘50s, rooted in the serial and post-serial movements (from which Franco Donatoni, Luciano Berio, Luigi Nono, Salvatore Sciarrino, Giacinto Scelsi, are the principals models, to mention only the Italians), dipped in the general phenomenon of timbrism (particularly spectralism), and acquainted with electronics. They draw from these sources various instruments of compositional technique and aspects of their poetics. In particular these composers, active from the ‘80s, develop new ways of construction of the temporal form of music. They share the goal to establish a new continuity, different from the tonal one but at the same time transcending the serial and post-serial disintegration and fragmentation. The primary means to this end is a new enhancement of the category of fi gure, as a clear and distinct, recognizable aggregate of pitches, intervals, register, durations, timbre, articulation, dynamics, and texture. Each composer elaborates the atonal fi gural material in different ways, emphasizing one aspect or another. For example, Fedele (1953) is a master in the management of form per se, Colardo (1953) in the activation of disturbed harmonic effects, Mirigliano (1950) in the creation of a slight tension from the smallest vibrations of sound, Soccio (1950) in the set up of movement by means of accumulations and discharges of energy, Cisternino (1957) in a Cagean-Scelsian emphasis on sound as such, Putignano (1960) in the suspension of time through the succession and transformation of images, Aralla (1960) in the foundation of form from below, from the concreteness of sound.

The paper reviews the provisions of the White Book on National Security of the Republic of Poland. It states that the issue of health security is not given adequate significance there. The accessibility of health services is considered, in general, solely in terms of their availability. The assumptions concerning the concept of providing the number of beds required in a state of threat to national security and in time of war do not take into account the current socio-economic conditions and need to be reviewed. The conclusions emphasize the dilemmas that emerge as a result of the unilateral promotion of a single category of national security, that is military security, in the context of ensuring health security.

Apesar dos progressos alcançados em todo o Mundo, a tuberculose continua a ser um problema de saúde pública muito sensível. Com 22 casos/100 mil habitantes registados em 2010, Portugal ainda não conseguiu atingir a categoria de país de baixa incidência. Com o aparecimento de cada vez mais casos de tuberculose multirresistente, os fármacos de primeira e segunda linha têm-se relevado ineficazes. Os novos desafios para a travagem deste fenómeno passam pela utilização de métodos mais rápidos e sensíveis para um diagnóstico precoce e também pela pesquisa de novas moléculas e de novos locais alvo. Despite progress made around the world, TB remains a very sensitive public health problem. With 22 cases/100 thousand inhabitants recorded in 2010, Portugal still failed to reach the country category of low incidence. With the increasing numbers of multidrug-resistant tuberculosis cases, drugs of first and second line have shown to be ineffective. New challenges for stopping this phenomenon are the use of rapid and sensitive methods for early diagnosis and also for researching new molecules and new target sites.

For communication-intensive parallel applications, the maximum degree of concurrency achievable is limited by the communication throughput made available by the network. In previous work [HPS94], we showed experimentally that the performance of certain parallel applications running on a workstation network can be improved significantly if a congestion control protocol is used to enhance network performance. In this paper, we characterize and analyze the communication requirements of a large class of supercomputing applications that fall under the category of fixed-point problems, amenable to solution by parallel iterative methods. This results in a set of interface and architectural features sufficient for the efficient implementation of the applications over a large-scale distributed system. In particular, we propose a direct link between the application and network layer, supporting congestion control actions at both ends. This in turn enhances the system's responsiveness to network congestion, improving performance. Measurements are given showing the efficacy of our scheme to support large-scale parallel computations.

We describe our work on shape-based image database search using the technique of modal matching. Modal matching employs a deformable shape decomposition that allows users to select example objects and have the computer efficiently sort the set of objects based on the similarity of their shape. Shapes are compared in terms of the types of nonrigid deformations (differences) that relate them. The modal decomposition provides deformation "control knobs" for flexible matching and thus allows for selecting weighted subsets of shape parameters that are deemed significant for a particular category or context. We demonstrate the utility of this approach for shape comparison in 2-D image databases; however, the general formulation is applicable to signals of any dimensionality.

In this paper we discuss a new type of query in Spatial Databases, called Trip Planning Query (TPQ). Given a set of points P in space, where each point belongs to a category, and given two points s and e, TPQ asks for the best trip that starts at s, passes through exactly one point from each category, and ends at e. An example of a TPQ is when a user wants to visit a set of different places and at the same time minimize the total travelling cost, e.g. what is the shortest travelling plan for me to visit an automobile shop, a CVS pharmacy outlet, and a Best Buy shop along my trip from A to B? The trip planning query is an extension of the well-known TSP problem and therefore is NP-hard. The difficulty of this query lies in the existence of multiple choices for each category. In this paper, we first study fast approximation algorithms for the trip planning query in a metric space, assuming that the data set fits in main memory, and give the theory analysis of their approximation bounds. Then, the trip planning query is examined for data sets that do not fit in main memory and must be stored on disk. For the disk-resident data, we consider two cases. In one case, we assume that the points are located in Euclidean space and indexed with an Rtree. In the other case, we consider the problem of points that lie on the edges of a spatial network (e.g. road network) and the distance between two points is defined using the shortest distance over the network. Finally, we give an experimental evaluation of the proposed algorithms using synthetic data sets generated on real road networks.
