Modular Form as a Curatorial Practice

This article discusses a curatorial approach to authorship as a model for thinking about what I describe as an iterative modular poem, a poetic text composed of appropriated segments. As a response to contemporary proliferation of literary and artistic works created by iterative means, i.e. through acts of appropriation, remixing and remediation, the article is an attempt at putting forward ‘the curatorial’ as an emerging paradigm of writing for the twenty-first century. The article approaches established paradigms of authorship, creativity and originality as inadequate with respect to contemporary experimental poetic practices to suggest a shift from creating to collecting and curating as a possible alternative model for thinking about instances of iterative creative writing. The argument focuses on Robert Fitterman’s Holocaust Museum (2011) as an example of an iterative modular poem and a text emblematic of such curatorial approach to authorship

Investigation of surface structure, electrokinetic and stability properties of highly dispersed Ho₂O₃-Yb₂O₃/SiO₂ nanocomposites

A series of highly dispersed Ho2O3–Yb2O3/SiO2 nanocomposites was synthesized using a liquid-phase method and examined using Fourier transform infrared (FTIR) spectroscopy, X-ray diffraction (XRD), nitrogen adsorption–desorption, transmission electron microscopy (TEM), Scanning Electron Microscopy (SEM), and photon correlation spectroscopy (PCS). X-ray fluorescence spectrometry (XRF) confirmed a similar amount of weight percentage of Ho, Yb and Si oxides in the prepared samples. Samples HoYbSi1 (Ho2O3:Yb2O3:SiO2 = 0.5:10:89.5, wt. %), HoYbSi2 (Ho2O3:Yb2O3:SiO2 = 1:10:89, wt. %) and HoYbSi3 (Ho2O3:Yb2O3:SiO2 = 2:10:88, wt. %) calcined at 550 °C are amorphous. TEM and SEM analysis confirm a sphere-like morphology with a quite homogeneous size and shape. As compared with the initial silica, the agglomerated particles of nanocomposites in the aqueous medium are in the range from 200 to 850 nm according to PCS data. The effect of anionic polyacrylic acid (PAA) adsorption on fumed silica (SiO2) and Ho2O3–Yb2O3/SiO2 nanocomposite surfaces on suspension stability was studied. The turbidymetry method was used to monitor the initial silica and triple nanooxides suspensions stability as a function of time

The reasons for occupational burnout in nursing

Autorzy szczegółowo omawiają czynniki wpływające na powstanie zespołu wypalenia zawodowego. Charakteryzują cechy osobowości człowieka najbardziej podatnego na rozwój tego zespołu. Zwracają uwagę, że stopień obciążenia pracą zależy od dwóch grup czynników, takich jak: wymagania oraz możliwości pielęgniarki ( inteligencja, zdolność zapamiętywania, plastyczność procesu myślenia, reaktywność układu nerwowego, odporność emocjonalna, sprawność psychomotoryczna).Here, the factors responsible for the occurrence of occupational burnout syndrome are discussed in detail. The personal features of a person who is highly susceptible for this syndrome are characterized. The attention is paid to the fact that the overload of work is dependent on two factors, namely a nurse’s expectations and scope (intelligence, memory, plasticity of thinking, nervous system reactivity, emotional resistance, psychomotor function)

The essence of occupational burnout

Autorzy charakteryzują zespół wypalenia zawodowe. Zwracają uwagę na objawy i stopnie tego zespołu. Podkreślają, że ze względu na konfrontację z negatywnymi emocjami, cierpieniem, przewlekłym stresem na rozwój tego zespołu narażeni są głownie lekarz i pielęgniarka.The authors characterize occupational burnout syndrome. They pay attention to its symptoms and levels. They emphasize that doctors and nurses are the ones exposed for the development of this condition most, as they have to deal with negative emotions, suffering and chronic stress

The effects of occupational burnout and stress-management measures

Przedmiotem rozważań są sposoby przywracania równowagi psychicznej czy inaczej, sposoby radzenia sobie ze stresem. Autorzy przedstawiają m.in. strategię proponowaną przez Lazarusa, Ratajczak, Sęk, Rogersa. Podkreślają, że terapia zespołu wypalenia nie jest łatwa. Działania zaradcze są dosyć trudne w realizacji i często wymagałyby głębokich zmian systemowych, takich jak lepsze pensje, bardziej sprzyjające warunki pracy czy większy autorytet pracownika. Terapią zespołu wypalenia powinni się zajmować profesjonaliści.The discussion is focused on the measures needed to reinstate emotional balance; in other words, stress management methods. The authors present, among others, strategies proposed by Lazarus, Ratajczak, Sęk, Rogers. They underline the fact that the treatment of occupational burnout is essentially difficult. The preventive methods are quite hard to introduce and often they would require fundamental changes in the system such as salary increases, more favourable working conditions or improving the perception of staff authority. The occupational burnout therapy should be handled by professionals

AGEs Secreted by Bacteria Are Involved in the Inflammatory Response

Advanced Glycated End Products (AGEs) are formed by non-enzymatic protein glycation and are implicated in several physiological aspects including cell aging and diseases. Recent data indicate that bacteria – although short lived – produce, metabolize and accumulate AGEs. Here we show that Escherichia coli cells secret AGEs by the energy-dependent efflux pump systems. Moreover, we show that in the presence of these AGEs there is an upshift of pro-inflammatory cytokins by mammalian cells. Thus, we propose that secretion of AGEs by bacteria is a novel avenue of bacterial-induced inflammation which is potentially important in the pathophysiology of bacterial infections. Moreover, the sensing of AGEs by the host cells may constitute a warning system for the presence of bacteria

D-Ribose Induces Cellular Protein Glycation and Impairs Mouse Spatial Cognition

BACKGROUND: D-ribose, an important reducing monosaccharide, is highly active in the glycation of proteins, and results in the rapid production of advanced glycation end products (AGEs) in vitro. However, whether D-ribose participates in glycation and leads to production of AGEs in vivo still requires investigation. METHODOLOGY/PRINCIPAL FINDINGS: Here we treated cultured cells and mice with D-ribose and D-glucose to compare ribosylation and glucosylation for production of AGEs. Treatment with D-ribose decreased cell viability and induced more AGE accumulation in cells. C57BL/6J mice intraperitoneally injected with D-ribose for 30 days showed high blood levels of glycated proteins and AGEs. Administration of high doses D-ribose also accelerated AGE formation in the mouse brain and induced impairment of spatial learning and memory ability according to the performance in Morris water maze test. CONCLUSIONS/SIGNIFICANCE: These data demonstrate that D-ribose but not D-glucose reacts rapidly with proteins and produces significant amounts of AGEs in both cultured cells and the mouse brain, leading to accumulation of AGEs which may impair mouse spatial cognition
