The monumental photographic exhibitions shown in many parts of the world during the first post-war decades were an important landmark in the history of photography. In this paper, two of the exhibitions became the starting point for a discussion about the perception of the medium of photography and its function in the 1950s and 1960s. The first, titled The Family of Man, was set up in 1955 by American photographer and curator Edward Steichen; the second, organised less than a decade later, was the worldwide exhibition Was ist der Mensch?, by the Austro-German journalist Karl Pawek. The two projects, although generally based on the same ideological and structural principles – a spatial installation building a narrative of a humanist nature – are antithetical to each other in terms of approach to the subject. Rooted in the complex context of the cultural, social, and political post-war period, they reveal a number of tensions hidden behind the strategies of constructing a visual narrative. The author mainly focuses on the issue of the representation of World War II experiences in photography, especially its most poignant event – the Holocaust. Stories about the human condition and realities of the contemporary iconosphere are investigated through relevant images. The reflections are based on case studies – the reception of these exhibitions in Germany and Poland. The analysis is supported by little known theories by Karl Pawek, by the voices of historians and critics of photography, as well as the latest developments on the subject. By revealing the circumstances of the reception of these projects and the resonance of their humanistic message questions are raised about ways of understanding the medium of photography within the broader history of visual culture. An important theme in the discussion are changes in the way we reflect on photography – criticism of a medium perceived as a visual language of universal character, taking into account the fundamental role of the historical, social, and cultural context in the process of creating meaning and interpreting images.
For the construction company, tendering is the most popular way of acquiring contracts. The decision to participate in the tender needs to be made carefully, as it affects the condition of the company and is an important aspect in its quest for success. The bid/no bid decision making is a complex process involving a number of factors. The research carried out so far has mainly concerned the identification of the various kinds of influences on contractors’ bidding decisions. The researchers, on the basis of contractors’ opinions, created rank lists in an attempt to categorize the factors. In this paper the author employs factor analysis which belongs to basic methods of multi-dimensional data analysis. The paper’s aim is first to depict an output set of observed variables, that is bid/no bid factors, in terms of a smaller set of latent variables which cannot be directly observed and then to interpret the dependencies between them.
One of the contract awarding systems in public sector in Poland is the Design & Build system. In this system, a client concludes a contract agreement with only one company, a contractor, in order to carry out both design and construction of works. While deciding on this form of delivery of a public project, the client is obliged to conduct a single proceeding aiming to select the contractor. In this paper, public works contracts awarded in the D&B system in Poland are analysed, whilst attention was put on the contracting modes and assessment criteria. The results are assessed against the experience of other countries and recommended methods for selection of the Design and Build contractor.
Anaphylaxis is an increasing problem in public health. Th e food allergens (mainly milk, eggs, and peanuts) are the most frequent cause of anaphylaxis in children and youth. In order to defi ne the cause of anaphylaxis, skin tests, the determination of the concentration of specifi c IgE in the blood and basophil activation test are conducted. In vitro tests are preferred due to the risk of allergic response during in vivo tests. Component-resolved diagnosis (CRD) is an additional tool in allergology, recommended in the third level of diagnostics when there are diagnostic doubts aft er the above mentioned tests have been carried out. The paper presents 3 cases of patients with anaphylactic response, and the application of CRD in these patients helped in planning the treatment. Patient 1 is a 4-year-old boy with diagnosed atopic dermatitis and bronchial asthma reported an anaphylactic shock at the age of seven months caused by cow’s milk and the exacerbation of bronchial asthma aft er eating some fruit. Patient 2 is a 35-year-old woman who has had anaphylactic shock three times: in June 2015, 2016, and 2017 and associates these episodes with the consumption of dumplings with a caramel, bun, and the last episode took place during physical exertion few hours aft er eating waffl e. Patient 3 is a 26-year-old man with one-time loss of consciousness after eating mixed nuts and drinking beer. CRD off ers the possibility to conduct a detailed diagnostic evaluation of patients with a history of anaphylactic reaction.
Polish photography in the first years after Poland regained independence remains a poorly documented area of research. Studies so far had mostly focused on the interpretation of the works of a few key artists from the avant-garde milieu (Witkacy) or photography (Jan Bułhak). It transpires however, that photography – not only as an artistic practice, but as poetic metaphor or an element of a broader aesthetic reflection – has functioned within the circle of the artistic avant-garde. An analysis of the presence of this medium in the consciousness and creativity of Polish artists allows us to see in a new light certain aspects of their technique and intellectual viewpoint. The article focuses on selected characteristics of this assimilation of modern reflection on photography by the Polish avant-garde artists in the first decade after the country regained independence. For the Formists – Tytus Czyżewski and Leon Chwistek – photography was an important point of reference as a metaphor of a new, cognitively uncertain, but also “deeper” way of seeing reality. It was an important help in defining the relationship between reality and its image and subject within a broader theoretical program (the theory of plurality of realities). For the Constructivists in turn – with Władysław Strzemiński and Mieczysław Szczuka at the forefront – photography became the means that enabled them to go beyond the usual schemes of capturing the external world, and as part of the concept of photomontage, it became a new material for creating an artistic reality. The dynamics of the process of assimilation of photography by the avant-garde artists was analysed in the context of the reception of new artistic trends born outside of Poland, primarily Futurism (the theory of photography by Anton Giulio Bragaglia) and Suprematism (reflection by Kazimierz Malewicz).
B a c k g r o u n d: A novel paradigm of diastolic heart failure with preserved ejection fraction (HFpEF) proposed the induction of coronary microvascular dysfunction by HFpEF comorbidities via a systemic pro-infl ammatory state and associated oxidative stress. Th e consequent nitric oxide deficiency would increase diastolic tension and favor fi brosis of adjacent myocardium, which implies not only left ventricular (LV), but all-chamber myocardial stiff ening. Our aim was to assess relations between low-grade chronic systemic infl ammation and left atrial (LA) pressure-volume relations in real-world HFpEF patients. Me t h o d s: We retrospectively analyzed medical records of 60 clinically stable HpEFF patients in sinus rhythm with assayed high-sensitive C-reactive protein (CRP) during the index hospitalization. Subjects with CRP >10 mg/L or coexistent diseases, including coronary artery disease, were excluded. LV and LA diameters and mitral E/E’ ratio (an index of LA pressure) were extracted from routine echocardiographic 46 Cyrus M. Sani, Elahn P.L. Pogue, et al. records. A surrogate measure of LA stiff ness was computed as the averaged mitral E/e’ ratio divided by LA diameter. R e s u l t s: With ascending CRP tertiles, we observed trends for elevated mitral E/e’ ratio (p <0.001), increased relative LV wall thickness (p = 0.01) and higher NYHA functional class (p = 0.02). Th e LA stiffness estimate and log-transformed CRP levels (log-CRP) were interrelated (r = 0.38, p = 0.003). On multivariate analysis, the LA stiff ness index was independently associated with log-CRP (β ± SEM: 0.21 ± 0.07, p = 0.007) and age (β ± SEM: 0.16 ± 0.07, p = 0.03), which was maintained upon adjustment for LV mass index and relative LV wall thickness. C o n c l u s i o n s: Low-grade chronic infl ammation may contribute to LA stiff ening additively to age and regardless of the magnitude of associated LV hypertrophy and concentricity. LA stiff ening can exacerbate symptoms of congestion in HFpEF jointly with LV remodeling.
