Quando devemos colocar um nome para uma imagem?
Authors: Freeman Norman H.
Published: July 2019

Este artigo aborda as implicações de dar nomes ou títulos a obras de arte e imagens e como isso interfere na interpretação. Argumenta que nomear uma obra é uma ferramenta para a leitura, especialmente durante o desenvolvimento de teorias intuitivas sobre arte por crianças, tornando-se uma parte positiva no processo de interpretação estética. Apresenta um modo de categorizar a função de nomear a obra. Comenta os resultados iniciais de um estudo empírico, indicando que, para a criança, atribuir um nome para a imagem é tão importante quanto identificar a intenção do artista.
Interdisciplinaridade - depoimento
Authors: Queiroz João Paulo
Published: July 2019

No depoimento em áudio dado ao evento “Docência Colaborativa e Interdisciplinaridade”[1], o professor João Paulo Queiroz (Portugal) reflete sobre a complexidade da sociedade contemporânea que resulta da transição da modernidade para a pós-modernidade, mudança que pode ser caracterizada como uma crise em relação a uma democracia avançada e integradora de todas as dimensões do desenvolvimento humano. A hibridação de contextos num mundo global conduz ao papel do pensamento artístico e criativo dentro de uma perspectiva interdisciplinar, implicando em uma atenção redobrada para a arte-educação. Sem arte na educação, a cidadania e o desenvolvimento pessoal são incompletos. Aponta a interdisciplinaridade como um vetor essencial para se compreender o papel e a construção do currículo da Arte na contemporaneidade.[1] Este evento, que reunirá o Seminário Internacional Prodocência UFRGS, o Colóquio Nacional PIBID UFRGS e o 10º Seminário Institucional do PIBID UFRGS, acontecerá de 6 a 8 de novembro de 2014 em Porto Alegre.

Mediação cultural como possibilidade de aprendizagem na infância
Authors: Pillotto Silvia Sell Duarte , Bohn Letícia Ribas Diefenthaeler
Published: July 2019

A educação infantil praticamente não tem acesso aos espaços culturais locais, especialmente por se pensar que as crianças não têm condições de apreciarem uma exposição de arte ou qualquer outro espaço que demande habilidades cognitivas. A indagação inicial da pesquisa centra-se nas seguintes questões: a mediação cultural pode mobilizar o aprendizado na infância? Como articular a mediação cultural nos espaços formais e não formais da educação, tendo a criança, o professor e o educador de museus como integrantes desses processos? A pesquisa busca refletir sobre outros modos de aprendizagem na infância para além dos muros escolares, com foco na mediação cultural, tendo duas unidades de educação infantil e o Museu Casa Fritz Alt como partícipes nesse processo. Esse artigo faz um recorte do arcabouço conceitual que dará subsídios para o diálogo com a pesquisa de campo, tendo o viés qualitativo como vertente.

Mediações culturais e contaminações estéticas
Authors: Martins Mirian Celeste
Published: July 2019

Mediação, uma palavra-valise, carregada de significações. Junte-se a ela outra palavra – cultura, e tem-se um baú de significações que perpassam por diversos conceitos e atuações. Cientes da diversidade e da riqueza dos múltiplos olhares possíveis a este emaranhado e complexo conteúdo, nos debruçamos para pinçar algumas de suas dimensões. Talvez o âmago desta proposição esteja conectado à busca de objetivos: Por que mediamos? Para ensinar arte ou para propor encontros significativos com ela? Pode a mediação cultural ser compreendida como contaminação estética? Estas são inquietações que atravessam o Grupo de Pesquisa “Mediação cultural: contaminações e provocações estéticas”. Neste artigo, parte-se de “medicações poéticas” para iniciar uma conversa silenciosa com o leitor. Virus, memes e contaminações desatam os fios que movem a pesquisa e se revelam na construção do livro “pensar juntos mediação cultural: [entre]laçando experiências e conceitos” (2014). Apresenta também uma leitura dos principais termos presentes no índice remissivo que evidenciam um modo de pensar a medição cultural como ação e não como função. Uma advertência ao leitor: “Agite-se antes de ler”.
A origem de projetos educacionais nas Bienais de Arte de São Paulo
Authors: Minerini Neto José
Published: July 2019

A educação nas Bienais de Arte de São Paulo surgiu porque o público visitante e a crítica de arte constataram que a I Bienal do Museu de Arte Moderna de São Paulo, em 1951, não havia organizado um projeto educacional para introduzir a arte moderna, especialmente a abstrata, aos brasileiros. Walter Zanini foi um dos críticos que destacaram esta falha, constatação presente entre os 10 mil estudantes que visitaram a mostra. Como reação imediata, foram realizadas palestras e encontros com organizadores da exposição e com comissários que acompanhavam as delegações dos países, chamadas representações nacionais, seguindo o formato da Bienal de Arte de Veneza, precursora das mostras bienais, referenciada pela Bienal de São Paulo. O primeiro projeto educacional da Bienal contou com monitores preparados em curso de História da Arte do Museu de Arte Moderna de São Paulo sob orientação do professor Wolfgang Pfeiffer. Os operários das indústrias e não os estudantes justificaram essa iniciativa, criticada posteriormente por Mário Pedrosa.
Livro de Artista
Authors: Linhares Ketta Cabral , Linhares Mário
Published: July 2019

Com quantas mãos se faz uma obra? Keta Cabral Linhares e Mário Linhares produziram um livro de artista a quatro mãos e dois pares de olhos. Viajaram para a Costa do Marfim, e desenharam, talvez como uma forma de viver e entender a vida, as suas próprias vidas e a dos outros. Definiram página a página as relações entre os registros e a forma, apropriando-se do tempo, construindo novos espaços. Arriscaram um diálogo através de um retrato, ao dividir as escolhas e multiplicar os traços. Enfim, riscaram e rabiscaram, deixando marcas que se arriscam a alcançar o outro na busca de si próprio. Os artistas dizem que “desenhar a África Negra é, inevitavelmente, um encontro com a essência do ser humano, com o estado mais puro e desprendido que alguma vez conseguimos ter. É a sensação de marcar a história pessoal com as palavras que estão por inventar.” E, para nós, no papel de observadores e fruidores da arte, a percorrer os livros com os artistas, ora olhando a esquerda, ora a direita, acima e abaixo tateando as páginas, no encadeamento da visão com o ritmo das mãos, nos quatro cantos, na tentativa de acompanhar o tempo do folhear, fica-nos uma experiência de partilha, que, sem querer, nos impele o olhar, e que também se põe a desenhar.O arquivo no formato wmv contendo o ensaio visual “Livro de Artista” encontra-se disponível em http://youtu.be/Y7lJTkcajec

Tools for Transparency in Central Government Spending
Authors: Rahal Charles
Published: July 2019

We first introduce centgovspend, an open source software library which provides functionality to automatically scrape and parse central government spending within the United Kingdom at the micro and meso levels. The library then optionally reconciles suppliers and subsequently analyzes payments made to private entities. We briefly discuss the policy environment surrounding the library before explaining the modular structure, implementation and execution which results in scraping over 4.9m payments worth over £3.5tn in value. We then provide two prototype applications in the fields of public administration and sociology; one of which analyzes government procurement across Standard Industry Classifier (SIC) and one which analyzes the social stratification of company officers and persons of significant control who supply the government. The project acts as a prototype in an international context, aiming to highlight an unrealised possibility of 'Big, Open Data' for public policy making and government efficiency.

Sunda dan Budaya Lalaban: Melacak Masa Lalu Budaya Makan Sunda
Authors: Rahman Fadly
Published: July 2019

AbstrakCitra budaya makan Sunda tidak dapat dipisahkan dari kekayaan vegetasinya. Beragam sayuran digunakan sebagai lalab, sebuah istilah Sunda untuk menyebut jenis-jenis sayuran, baik yang tumbuh liar maupun yang dibudidayakan untuk dipilih sebagai hidangan utama Sunda. Tidak mengherankan jika di lingkungan rumah tangga Sunda atau rumah makan Sunda, sayuran mentah atau yang direbus yang dilengkapi dengan sambal terasi kerap disajikan seakan menjadi menu wajib. Tradisi lalab sendiri seringkali diasosiasikan dengan lingkungan alam Sunda berupa citra tanah suburnya yang mendukung pertumbuhan banyak jenis tanaman bermanfaat untuk bahan lalab. Setidaknya tradisi ini telah membentuk keunikan budaya makan Sunda jika dibandingkan dengan budaya makan di wilayah lainnya di Indonesia. Hal yang menjadi pertanyaan, sejak kapan tradisi lalab melekat dalam budaya makan Sunda? Artikel ini secara historis menjelajahi akar dari tradisi lalab dihubungkan dengan fakta-fakta arkeologis, naskah-naskah kuno, dan penelitian seputar ilmu botani dan makanan pada masa kolonial.Kata kunci: budaya makan Sunda, lalab, sejarah, tradisiAbstractThe image of Sundanese food culture is inseparable from its abundant vegetation. Various vegetables are used as lalab, a Sundanese term used to mention sorts of uncultivated and cultivated vegetables which are selected as the main dishes of Sundanese food. No wonder in the Sundanese households or in Sundanese restaurants, raw and boiled vegetables with sambalterasi (hot sauce of chilli with shrimp paste) always served as a kind of mandatory menu. Lalab tradition itself is often associated with the Sundanesenatural environment havingthe image of fertile soil which support the growth of many plants for lalab. At least this tradition has shaped the uniqueness of Sundanese food culture if compared with other food culture in different regions of Indonesia. The question is since when lalab tradition is inherent in Sundanese food culture? This article explores historically the roots of lalab tradition by making connection with archaeological facts, old manuscripts and scientific research on botanical and food sciences in colonial era.Keywords: Sundanese food culture, lalab, history, tradition

Reactivity of calcium carbonate prepared from flue gas desulfurization gypsum
Authors: Jurišová Jana , Danielik Vladimír , Fellner Pavel , Králik Milan , Foltinovič Tomáš
Published: July 2019

Reactivity of various calcium carbonate samples for flue gas desulfurization was tested. Two groups of CaCO3 samples were considered; natural limestone containing calcite phase dominantly and samples prepared by the conversion of gypsum with ammonium and carbon dioxide (precipitated CaCO3) containing different amounts of calcite, aragonite and vaterite.

Reactivity of precipitated calcium carbonate depends primarily on the particle size, similarly as in case of industrial samples. The initial reaction rate was comparable with the industrial limestones for samples with the average particle size lower than 15 μm. However, the conversion of laboratory samples was significantly higher after 5 min of the reaction.

Phase composition of the precipitated calcium carbonate has a minor but noticeable impact on the reactivity. The presence of vaterite slightly increased the reactivity, which is in accordance with its lower compact structure in comparison with calcite and aragonite. Unexpected effect of the increased content of aragonite, which is the most compact phase in comparison with calcite and vaterite, was observed. If calcium carbonate contains up to approximately 30 % of aragonite the reactivity increases, which can be explained by the SEM pictures showing agglomerate composition with relatively high specific surface. At higher contents of aragonite, the reactivity decreases. All the obtained results proved the suitability of precipitated CaCO3 prepared from flue gas desulfurization gypsum to be recycled in the flue gas desulfurization process.
Synthesis, crystal structure, infrared spectrum, and thermal properties of [Ni(1,10-phenanthroline)3](fumarate)·9H2O complex with hydrogen bonded supramolecular layers involving fumarate anions
Authors: Uhrinová Anna , Černák Juraj
Published: July 2019

From the aqueous-ethanolic system Ni(OH)2—H2
fum—phen (H2fum = fumaric acid, phen = 1,10-phenanthroline), novel complex [Ni(phen)3](fum)·9H2O (1) was isolated and characterized by chemical analyses and FT-IR spectroscopy. Results of single crystal X-ray structure analysis have shown that the ionic crystal structure of 1 is built of [Ni(phen)3]2+ complex cations, fumarate dianions and nine crystallographically independent water molecules of crystallization. The Ni(II) atom exhibits hexa-coordination by three phen ligands with mean Ni-N bond length of 2.090 Å. Water molecules form hydrophilic supramolecular layers with fumarate dianions via extended network of O—H···O type hydrogen bonds with O···O distances from the range of 2.676(2)—2. 916(2) Å; hydrophobic complex cations are embedded between these layers. Thermal study of 1 has shown that endothermic dehydration in the temperature range of 95—195 °C takes at least two steps of the process.

Graphical Abstract

Crystal structure of [Ni(phen)3]fum·9H2O (phen = 1,10-phenanthroline; H2
fum = fumaric acid) which is built of supramolecular layers formed by hydrogen bonded water solvate molecules and fum dianions and between the supramolecular layers embedded [Ni(phen)3]2+ complex cations is described here.
On local aromaticity of selected model aza-[n]circulenes (n = 6, 7, 8 and 9): Density functional theoretical study
Authors: Cagardová Denisa , Lukeš Vladimír , Matúška Ján , Poliak Peter
Published: July 2019

A computational study using density functional theory is reported for selected model aza[n]circulenes (n = 6, 7, 8 and 9) and their derivatives consisting of pyrrole and benzene units. Local aromaticity of central rings was discussed and analyzed using theoretical structural indices. Depending on their molecular structures, energies of the highest occupied and lowest unoccupied molecular orbitals change from –5.23 eV to –4.08 eV and from –1.97 eV to –0.41 eV, respectively. Based on B3LYP calculated optimal geometries, electronic structure of molecules and their charge transport properties resulted in the suggestion of three planar molecules containing three or four pyrrole units as potential candidates for p-type semiconductors. Hole drift mobilities for ideal stacked dimers of these potential semiconductors were calculated and they range from 0.94 cm2·V−1·s−1 to 7.33 cm2·V−1·s−1.

Published: July 2019

Electrospun materials are good candidates for the design of tissue regeneration scaffolds as they can simulate the natural surroundings of tissue cells. The study proposes electrospun polycaprolactone (PCL)/cefuroxime (CFU) scaffolds for human cell culture and investigates the influence of the antibiotic content on scaffold morphology, thermal and mechanical properties. The increase in the CFU concentration resulted in the reduction of fiber diameter and number of deformations. It also influenced the reduction of scaffold thermal enthalpies and improved scaffold break strength. With regard to cell growth, the scaffolds showed precedence in greater colonization of the HeLa cells. Finally, these scaffolds showed compatibility with standard human cell lines, and thus they can be used for the repair of damaged tissues.

Subject and purpose of work: The main goal of the article is to prove the impact of the Wałbrzych Special Economic Zone (WSSE) “Invest Park” on the development of the Wałbrzych Agglomeration region.

Materials and methods: The research carried out in 2017-2018 involved three groups of respondents: Wałbrzych Agglomeration residents, entrepreneurs and local government authorities. The study was supplemented with the information from WSSE “Invest Park”.

Results: For all three groups of respondents, WSSE “Invest Park” plays an important role in the development of the Wałbrzych Agglomeration. Its creation had the greatest impact on reducing the unemployment rate and also on improving the infrastructure. It is also important that WSSE top many rankings, gaining the first position as one of the best investment areas.

Conclusions: Establishing the WSSE in the area of the Wałbrzych Agglomeration has had a significant impact on the development of the region. This development is visible in the activities undertaken in the zone, attracting investors and creating new investment areas.
The influence of riparian woodlands on the thermal conditions of small lowland streams during the summer
Authors: Łaszewski Maksym , Kiryła Wojciech
Published: July 2019

Riparian woodlands significantly affect the water quality of streams and rivers. Thus, we examined whether the presence of woodlands in riparian buffer zones also impacts the thermal characteristics of lowland streams during the summer. Water temperature data were recorded with digital temperature loggers located in eight quasi-natural sites across the Garwolin Plain in central Poland. The mean, maximum, minimum, and mean daily range parameters were calculated for the whole study period from July to September 2017 with a 30 min. resolution. The percentage of woodlands in the catchment area and buffer zone along the streams was estimated based on satellite images from the Sentinel-1 and Sentinel-2 missions. The Random Forest method was used in the classification process with an accuracy of 96%. The similarity of measurement sites in terms of water temperature was determined using cluster analysis (Ward method), while a Spearman correlation coefficient was applied to compare thermal parameters with the percentage of woodland areas.

The results indicate that water temperature patterns across the measurement sites varied, with mean temperatures ranging from 14.4°C in site T8 to 16.3°C in site T1. Furthermore, the correlation analysis confirmed our hypothesis that the presence of woodland areas does not significantly alter the thermal parameters of lowland streams. Moreover, the cluster analysis showed that sites with significantly different percentages of woodland areas were closely linked due to the similar distributions of water temperature values. However, it must be emphasised that the lack of riparian woodlands in buffer zones does not exclude the presence of shade associated with shrubs and grasses, as well as aquatic plants. In consequence, more advanced indicators of riparian shade, such as vegetation mapping using unmanned aerial vehicle (UAV) or hemispherical photography, should be used for small lowland streams.
The influence of relative humidity on fires in forests of Central Poland
Authors: Konca-Kędzierska Krystyna , Pianko-Kluczyńska Krystyna
Published: July 2019

The purpose of the present work was to answer the question of how and to what extent information about low air humidity in a selected area can be used in determining the fire risk. The central region as defined in the Classification of Territorial Units for Statistics (NUTS) was selected for the study, because this classification is also used in the National Fire Information System, which provides data on the number of forest fires. Data on humidity for a given region were taken from the synoptic or climatic station of The Institute of Meteorology and Water Management – National Research Institute (IMGW-PIB) located in the region.

Two independent experiments were conducted based on various methodological assumptions. In experiment A, the main focus was on humidity deficit, as defined by nine different indicators. Using the relative risk and the Jaccard index, their connection to fire cases of third class or higher was studied. A class reconstruction of the number of fires was also carried out using the fuzzy analogues method, and the obtained reconstructions were evaluated using cross-correlation indicators in contingency tables. In experiment B, correlation relationships between the number of fires and the annual characteristics of relative humidity were studied. In order to use the association measures in the cross-tabulation tables, the number of fires and humidity characteristics were categorised using quantiles. The relationship between the number of fires and the percentage share of low-humidity (<40%) days in the year was tested using the Mann–Whitney test.

The obtained values of the examined correlation indices and the analysis of correlation relationships emphasise the important role of relative humidity dynamics in determining the fire risk.

Authors: Olayemi D. O. , Onakpa M. M. , Jegede O. C.
Published: July 2019

The development of host resistance to anthelmintics and the increasing cost of commercial anthelmintics have encouraged the need for thein vitroanthelmintic evaluation of crude extract and fractions ofHymenodictyon pachyantaplant as alternative drugs againstHaemonchus contortus.H. contortusis one of the most prevalent and highly pathogenic parasitic nematodes in small ruminant farming globally.H. pachyantastem bark is a prospective plant used by the local and indigenous farmers of Nsukka, Enugu state, Nigeria. The stem bark ofH. pachyantawere collected, dried, pulverized and extracted with 80 % methanol. The purpose of this study was to investigate thein vitroanthelmintic effects of these crude extract and fractions againstH. contortusin sheep and goats. The two extracts (crude and fractions) ofH. pachyantawere tested by the egg hatch assay (EHA) and the larval development inhibition assays (LDIA) and to compared the results with albendazole (as the positive control). The concentrations for the crude extract and albendazole used for this study were 0.78, 1.56, 3.125, 6.25 and 12.5 mg.ml−1. The results demonstrated that the crude extracts, fractions and albendazole all at the concentration doses of 12.5 mg.ml−1produced 100 % inhibition of egg hatching and larval development. Statistically, there was no significant difference (P > 0.05) in the mean percentage inhibition of egg hatching and larval development inhibition of the crude extracts and fractions when compared with albendazole. However, a significant difference (P < 0.05) was observed with n-butanol fraction which inhibited 96.17 % of egg hatchability. All of the extracts and albendazole showed ovicidal and larvicidal effects and were able to induce over 50 % of the egg hatching and mortality of larvae at the concentration ranges of 0.78—12.5 mg.ml−1. The results obtained from our study suggest thatH. pachyantahad ovicidal and larvicidal activity againstH. contortusand that the bioactive plants compounds responsible for this effect could be attributed to the presence of tannins, alkaloids and the saponins contained in the crude extracts.

In artistic gymnastics, athletes need to compose their floor exercise routines in accordance with the Code of Points which is provided by the International Gymnastics Federation. In view of the latest rule modifications subsequent to the 2016 Olympic Games, this study investigates recent changes in judges’ scorings with respect to changes in the characteristics of floor exercise routines in world elite male gymnasts. Therefore, all floor exercise routines (n = 25) performed in the men’s floor exercise finals at the World Championships in 2013 (WC13), 2015 (WC15) and 2017 (WC17) were examined using video analysis. Gymnasts’ scores (difficulty, execution and final scores), element group distributions and further exercise characteristics (e.g., the total amount of somersaults, twists, and landing errors) were defined as variables. Decreases in difficulty and execution scores were revealed for WC17 compared to WC15 and WC13, respectively (p < .01). Additionally, a decrease in the number of backward jumped elements was observed at WC17 (p < .01), whereas the number of forward jumped elements increased (p < .01). Furthermore, a significantly increased number of landing errors (p < .05) negatively correlated with the decrease in execution (p < .001) and final scores (p < .05). To conclude, current compositional trends in men’s floor exercise encourage to include difficult forward jumps and multiple twisting connections in consideration of prudent teaching with respect to the gymnasts’ individual abilities and the decisive influence of stick landings.

This study aimed to compare force, velocity, and power output collected under different loads, as well as the force-velocity (F-V) relationship between three measurement methods. Thirteen male judokas were tested under four loading conditions (20, 40, 60, and 80 kg) in the countermovement jump (CMJ) exercise, while mechanical output data were collected by three measurement methods: the Samozino's method (SAM), a force platform (FP), and a linear velocity transducer (LVT). The variables of the linear F-V relationship (maximum force [F0], maximum velocity [V0], F-V slope, and maximum power [P0]) were determined. The results revealed that (1) the LVT overestimated the mechanical output as compared to the SAM and FP methods, especially under light loading conditions, (2) the SAM provided the lowest magnitude for all mechanical output, (3) the F-V relationships were highly linear either for the SAM (r = 0.99), FP (r = 0.97), and LVT (r = 0.96) methods, (4) the F-V slope obtained by the LVT differed with respect to the other methods due to a larger V0 (5.28 ± 1.48 m·s-1) compared to the SAM (2.98 ± 0.64 m·s-1) and FP (3.06 ± 0.42 m·s-1), and (5) the methods were significantly correlated for F0 and P0, but not for V0 or F-V slope. These results only support the accuracy of the SAM and FP to determine the F-V relationship during the CMJ exercise. The very large correlations of the SAM and LVT methods with respect to the FP (presumed gold-standard) for the mean values of force, velocity and power support their concurrent validity for the assessment of mechanical output under individual loads.

Background: A significant proportion of patients with ST-segment elevation myocardial infarction (STEMI) have multivessel coronary artery disease (MVD), and they are at high risk for recurrent cardiac events. The aim of the present study was to analyze the impact of MVD on long-term cardiovascular mortality in STEMI patients treated with primary percutaneous coronary intervention (pPCI). Method: This study included 3,115 consecutive STEMI patients hospitalized in the Coronary Care Unit of the Clinical Centre of Serbia, between November 2005 and January 2012. Patients were divided in two groups: MVD and no MVD. MVD disease was defined as stenosis greater than 50% by visual assessment in more than one major coronary artery. Primary PCI was limited to the infarct-related artery (IRA). Cardiovascular mortality was defined as any death from cardiovascular reason (myocardial reinfarction, low-output heart failure, and sudden death). Patients presenting with cardiogenic shock were excluded. Patients were followed-up for 6 years after enrollment. Results: Among 3,115 analyzed patients, 1,352 (43.4%) patients had no MVD and 1,763 (56.6%) had MVD; among patients with MVD, 926 (52.6%) had two-vessel disease and 837 (47.4%) had three-vessel disease. Compared with patients with single-vessel disease, patients with MVD were older, had longer pain duration, and presented more often with heart failure; they were more likely to have previous coronary artery disease, diabetes, hypertension, and chronic kidney disease; post-procedural flow TIMI <3 was more frequently observed in patients with MVD than in patients with no MVD (5.9% vs. 3.1%, p <0.001). Patients with MVD had lower left ventricular ejection fraction than patients with single-vessel disease: 45% (interquartile range [IQR] 40¬–55%) vs. 50% (IQR 43–55%), p <0.001. Revascularization of non-IRA lesions was performed at index hospitalization in 1,075 (61%) patients, and in 602 (34.1%) patients revascularization was performed in the first few months after pPCI (median 1.5 months, IQR 1–2.5 months); coronary artery bypass grafting was performed in 291 (18.4%) patients and PCI (with stent implantation) in 1,368 (81.6%) patients. Six-year cardiovascular mortality was significantly higher in patients with MVD than in patients with single-vessel disease (10.4% vs. 4.6%, p <0.001). In multivariate Cox regression analysis, MVD remained an independent predictor for 6-year cardiovascular mortality (HR 1.55, 95% CI 1.11–2.06, p = 0.041). Conclusion: In STEMI patients treated with pPCI, the presence of MVD remained an independent predictor for higher long-term cardiovascular mortality despite early revascularization of the remaining stenosis in non-IRA.

Published: July 2019

Background and purpose: The importance of soft-skills that managers can use to promote job satisfaction of employees is well known. Previous research has shown several different ways how managers can influence job satisfaction of employees, mostly in the form of external factors. Very little research is available on internal factors. This led us to the following research question: How managers’ competencies influence job satisfaction of employees?

Design/Methodology/Approach: We have performed a pencil-paper survey among employees in the hotel industry sector. The questionnaire asked respondents to evaluate the competencies of their supervisors; later, we asked respondents to evaluate what influences their job satisfaction, and, in the final part, we collected some demographical data.

Results: The results show a weak, but still detectable, positive correlation between the competencies of managers and job satisfaction of employees in the factor that we have labelled “work itself”. We have not found any correlation between the competencies of managers and job satisfaction of employees with regard to working conditions or possibilities of career development.

Conclusion: The competency of managers has an influence on job satisfaction of employees with regard to work itself. Although correlations that we have found are weak, they do exist, and have to be taken into account when it comes to discussing job satisfaction of employees. Managers who understand this core competency and promote it onwards to their employees will influence the job satisfaction of employees through this competency.

Authors: Shamout Mohamed Dawood
Published: July 2019

Background and purpose: Little are known about the nature of the interaction between supply chain analytics, supply chain innovation and robustness capability. The purpose of this paper is to examine the effectiveness of supply chain analytics in enhancing firms supply chain innovation and robustness capability in the Arabian context.

Design/Methods: Using knowledge-based view and survey data from line managers in supply and logistics departments, the present study uses variance-based structural equation modeling (PLS-SEM) to diagnose the association between supply chain analytics, supply chain innovation and robustness capability.

Findings: Results suggest that supply chain analytics exerted significant impact on supply chain innovation and not on robustness capability. It appears that supply chain innovation exerted a significant impact on robustness capability, in doing so, supply chain innovation mediates the link supply chain analytics and robustness capability.

Conclusion: The outcome of this study points to the importance of supply chain analytics as a functional tool for supply chain and/or logistic routes stability and success. The paper concludes supply chain analytics can help managers have access timely and useful data for greater innovation; and that supply chain innovation is reliant not only on data, but also on firms’ analytic capabilities.
‘And Yet, What Would We Be Without Memory?’ Visualizing Memory in Two Canadian Graphic Texts
Authors: Drewniak Dagmara
Published: July 2019

Since “we live in a culture of confession” (Gilmore 2001: 2; Rak 2005: 2) a rapidly growing popularity of various forms of life writing seems understandable. The question of memory is usually an important part of the majority of autobiographical texts. Taking into account both the popularity of life writing genres and their recent proliferation, it is interesting to see how the question “what would we be without memory?” (Sebald 1998 [1995]: 255) resonates within more experimental auto/biographical texts such as a graphic memoir/novel I Was a Child of Holocaust Survivors (2006) by Bernice Eisenstein and a volume of illustrated poetry and a biographical elegy published together as Correspondences (2013) by Anne Michaels and Bernice Eisenstein. These two experimental works, though representing disparate forms of writing, offer new stances on visualization of memory and correspondences between text and visual image. The aim of this paper is to analyze the ways in which the two authors discuss memory as a fluid concept yet, at the same time, one having its strong, ghostly presence. The discussion will also focus on the interplay between memory and postmemory as well as correspondences between the texts and the equally important visual forms accompanying them such as drawings, portraits, sketches, and the bookbinding itself.
The Morphosemantic Transparency/Opacity of Novel English Analogical Compounds and Compound Families
Authors: Mattiello Elisa , Dressler Wolfgang U.
Published: July 2019

This study deals with novel English analogical compounds, i.e. compounds obtained via either a unique model (e.g.beefcakeaftercheesecake) or a schema model: e.g.,green-collarbased onwhite-collar,blue-collar,pink-collar, and other X-collarcompounds. The study aims, first, to inspect whether novel analogical compounds maintain the same degree of morphosemantic transparency/opacity as their models, and, second, to find out the role played by the compound constituents in the constitution of compound families, such as X-collarand others. To these aims, the study proposes a scale of morphosemantic transparency/opacity for the analysis of compound constituents. In particular, the compound constituents in our database (115 examples) are analysed in connection with: 1) their degree of transparency (vs. opacity, including metaphorical/metonymic meaning), linked to their semantic contribution in the construction of the whole compound’s meaning, and 2) their part-of-speech. Against the common assumption that productive word-formation rules mostly create morphosemantically transparent new words, or that rule productivity is closely connected with transparency, the study of our database demonstrates that novel analogical compounds tend to maintain the same transparency/opacity degree as their models. It also shows that, in nuclear families and subfamilies of compounds, the part-of-speech of the constituents, their degree of transparency/opacity, and their semantic relation are reproduced in all members of the analogical set.
