Correlazioni positive tra spiritualità e salute: i risultati di alcune indagini / Positive correlations between spirituality and health: results from some surveys
Authors: Morocutti Paolo
Published: April 2019

La dimensione religiosa dell’uomo contribuisce in modo sostanziale al mantenimento della condizione medica generale, migliorando e preservando la qualità della vita. Quanto fa bene la fede? La preghiera fa ammalare meno e guarire prima? La partecipazione ai servizi religiosi porta realmente un effetto positivo sulla salute? Gli studi esaminati in questo articolo sembrano rispondere affermativamente a queste domande, evidenziando la stretta correlazione tra religiosità/spiritualità, salute e benessere fisico e psicologico. L’impatto antropologico e sociologico di tale realtà conduce ad evidenti riflessioni storiche e filosofiche, ma anche mediche e bioetiche, generando l’esigenza di una profonda trasformazione nella formazione del personale sanitario, dove l’aspetto religioso o spirituale non è ritenuto importante, né rilevante nell’approccio medico per la cura e l’assistenza del paziente. Nonostante ciò, numerosi studi approfondiscono ed attestano l’importanza di questo aspetto sia dei singoli, sia dell’intera popolazione. ---------- Religious dimension of man contributes substantially to maintain general medical condition, improving and preserving quality of life. How good is faith? Does prayer make you sick less and get better sooner? Does participation in religious services actually have a positive effect on health? The studies examined within this article seem to answer positively to these questions, highlighting the close correlation between religiosity / spirituality, health and physical and psychological well-being. The anthropological and sociological impact of this reality leads to evident historical and philosophical as well as medical and bioethical reflections, generating the need for a deep transformation of health personnel training, where the religious or spiritual aspect are not considered as important, nor relevant for medical approach to patient’s care. Nevertheless, several studies address and highlight the importance of this aspect for both individuals and whole population.
Oxygen-ozone therapy in arthroplasty infections
Authors: De Lisi Alessandra Vittoria , Franzini Marianno , Ricevuti Giovanni
Published: April 2019

The prevention of surgical site infections is a priority within the objectives of the National Health System. The negative consequences of postoperative infections (morbidity, duration of hospitalization, mortality) are particularly serious events for the individual patient and for the community, given both the welfare resources needed to treat them, and the continued growth of the phenomenon of antibiotic resistance. In a global health context in which evidence-based medicine has established itself, all medical interventions must be reconsidered in the light of what can be inferred from the literature evaluated according to strict methodological criteria, all the more so when the evidence is available and unanimously shared. The future objective will be to introduce in the national guidelines a protocol involving the use of ozone therapy alongside antibiotic therapy, both in the prevention and treatment of infections, to avoid the emergence of antibiotic resistance and thus reduce the expenditure of the national health system.

Vedolizumab Achieved Clinical and Histologic Remission in a Patient with Lung Cancer Who Had a Steroid-Refractory Upper Gastrointestinal Injury Due to Nivolumab Treatment
Authors: Tran Cynthia Nguyen , Abu-Sbeih Hamzah , Luo Wenyi , Lu Yang , Wang Yinghong
Published: April 2019

Immune checkpoint inhibitors (ICIs) have emerged as a novel therapeutic class for various malignancies. Their immune upregulation promotes significant anti-tumor effect, but simultaneously, can also result in treatment-limiting immune-related adverse events (irAEs). The data on upper gastrointestinal (GI) tract irAEs are sparse. We herein describe a case of steroid-dependent upper GI toxicity with nivolumab (an anti-programmed death [PD] protein-1) that achieved clinical and histological remission with vedolizumab treatment (a GI tract targeted anti-integrin antibody). A 65-year-old male patient with progressive lung cancer was treated with nivolumab and following 16 cycles, developed severe nausea, vomiting, and epigastric abdominal cramps requiring five hospitalizations. His initial esophagogastroduodenoscopy (EGD) showed active inflammation in both the stomach and duodenum. Nivolumab was discontinued, but despite treatment with multiple steroid courses, his symptoms always recurred during prednisone taper. Clinical remission was ultimately achieved with vedolizumab. His last EGD after five infusions of vedolizumab demonstrated resolution of inflammation. His lung cancer has since relapsed and the treatment plan was to resume nivolumab concurrently with vedolizumab. In conclusion, ICIs, such as nivolumab, have emerged as therapy for various malignancies. Their use can be associated with various irAEs including the upper GI adverse events which is uncommon. This case scenario showed that vedolizumab can provide a steroid-sparing therapeutic effect to achieve remission of upper GI irAEs even in cases where multiple steroid courses have failed.
Arbeitsgemeinschaft: Topological Cyclic Homology

Introduced by Bökstedt–Hsiang–Madsen in the nineties, topological cyclic homology is a manifestation of the dual visions of Connes–Tsygan and Waldhausen to extend de Rham cohomology to a noncommutative setting and to replace algebra by higher algebra.

The study of complex relationships among the elements of a large collection of random variables lead to the development of a number of areas in probability and statistics such as probabilistic network analysis or random matrix theory. The aim of the workshop was to address the challenge to develop a coherent mathematical framework within which these areas can be integrated, for a successful analysis of massive and complicated data sets.
Technical Note: Deep Learning for Creating Surrogate Models of Precipitation in Earth System Models
Authors: Weber Theodore , Corotan Austin , Hutchinson Brian , Kravitz Ben , Link Robert
Published: April 2019

Abstract. We investigate techniques for using deep neural networks to produce surrogate models for short term climate forecasts. A convolutional neural network is trained on 97 years of monthly precipitation output from the 1pctCO2 run (the CO2 concentration increases by 1 % per year) simulated by the CanESM2 Earth System Model. The neural network clearly outperforms a persistence forecast and does not show substantially degraded performance even when the forecast length is extended to 120 months. The model is prone to underpredicting precipitation in areas characterized by intense precipitation events. Scheduled sampling (forcing the model to gradually use its own past predictions rather than ground truth) is essential for avoiding amplification of early forecasting errors. However, the use of scheduled sampling also necessitates preforecasting (generating forecasts prior to the first forecast date) to obtain adequate performance for the first few prediction time steps. We document the training procedures and hyperparameter optimization process for researchers who wish to extend the use of neural networks in developing surrogate models.
The effect of marine aggregate parameterisations on global biogeochemical model performance
Authors: Niemeyer Daniela , Kriest Iris , Oschlies Andreas
Published: April 2019

Abstract. Particle aggregation determines the particle flux length scale, possibly the marine oxygen concentration and thus affecting the volume of oxygen minimum zones (OMZs) that are of special relevance for ocean nutrient cycles and marine ecosystems, and that have been found to expand faster than can be explained by current state-of-the-art models. To investigate the impact of particle aggregation on global model performance, we carried out a sensitivity study with different parameterisations of marine aggregates and two different model resolutions. Model performance was investigated with respect to global nutrient and oxygen concentrations, as well as extent and location of OMZs. Results show that including an aggregation model improves the representation of OMZs. Moreover, we found that besides a fine spatial resolution of the model grid, the consideration of porous particles, an intermediate to high particle sinking speed and a moderate to high stickiness improve the model fit to both, global distributions of dissolved inorganic tracers and regional patterns of OMZs, compared to a model without aggregation. Our model results therefore suggest that improvements not only in the model physics, but also in the description of particle aggregation processes can play a substantial role in improving the representation of dissolved inorganic tracers and OMZs on a global scale. However, dissolved inorganic tracers are apparently not sufficient for a global model calibration, which could necessitate global model calibration against a global observational dataset of marine organic particles.
Glacier equilibrium line altitude variations during the “Little Ice Age” in the Mediterranean Andes (30◦–37◦ S)
Authors: González-Reyes Álvaro , Bravo Claudio , Vuille Mathias , Jacques-Coper Martin , Rojas Maisa , Sagredo Esteban , McPhee James
Published: April 2019

Abstract. The "Little Ice Age" (LIA; 1500–1850 Common Era (CE)), has long been recognized as the last period when mountain glaciers in many regions of the Northern Hemisphere (NH) recorded extensive growth intervals in terms of their ice mass and frontal position. The knowledge about this relevant paleoclimatic interval is vast in mountainous regions such as the Alps and Rocky Mountains in North America. However, in extra-tropical Andean sub-regions such as the Mediterranean Andes of Chile and Argentina (MA; 30º–37º S), the LIA has been poorly documented. Paradoxically, the few climate reconstructions performed in the MA based on lake sediments and tree rings do not show clear evidence of a LIA climate anomaly as observed in the NH. In addition, recent studies have demonstrated temporal differences between mean air temperature variations across the last millennium between both hemispheres. This motivates our hypothesis that the LIA period was not associated with a significant climate perturbation in the MA region. Considering this background, we performed an experiment using daily climatic variables from three Global Climate Models (GCMs) to force a novel glaciological model. In this way, we simulated temporal variations of the glacier equilibrium-line altitude (ELA) to evaluate the glacier response during the period 1500–1848 CE. Overall, each GCM shows temporal changes in annual ELA, with anomalously low elevations during 1640–1670 and 1800–1848 CE. An interval with high ELA values was identified during 1550–1575 CE. The spectral properties of the mean annual ELA in each GCM present significant periodicities between 2–7 years, and also significant decadal to multi-decadal signals. In addition, significant and coherent cycles at interannual to multi-decadal scales were detected between modeled mean annual ELAs and the first EOF1 extracted from Sea Surface Temperature (SST) within the El Niño 3.4 of each GCM. Finally, significant Pearson correlation coefficients were obtained between the mean annual ELA and Pacific SST on interannual to multi-decadal timescales. According to our findings, we propose that Pacific SST variability was the main modulator of temporal changes of the ELA in the MA region of South America during 1500–1848 CE.
Tipping the ENSO into a permanent El Niño can trigger state transitions in global terrestrial ecosystems
Authors: Duque-Villegas Mateo , Salazar Juan F. , Rendón Angela M.
Published: April 2019

Abstract. Some large-scale components of the Earth's climate system have been identified as policy-relevant tipping elements, meaning that anthropogenic forcing and perturbations may push them across a tipping point threshold, with potential global scale impact on ecosystems and concomitant environmental and social phenomena. A pronounced change in the amplitude and/or frequency of the El Niño-Southern Oscillation (ENSO) is among such tipping elements. Here we use the Planet Simulator (PlaSim), an Earth system model of intermediate complexity, to investigate the potential impact on global climate and terrestrial ecosystems of shifting the current dynamics of the ENSO into a permanent El Niño. When forced with sea surface temperature (SST) derived from observations, the PlaSim model yields a realistic representation of large-scale climatological patterns, including realistic estimates of the global energy and water balances, and gross primary production. In a permanent El Niño state, we found significant differences in the global distribution of water and energy fluxes, and associated impacts on gross primary production, indicating that vegetation productivity decreases in the tropics whereas it increases in temperate and boreal regions. We identify regions in which these El Niño-induced changes are consistent with potential state transitions in global terrestrial ecosystems, including potential dieback of the Amazon rainforest, southward expansion of the Sahel, and further aridification of Australia.
Development of turbulent scheme in the FLEXPART-AROME v1.2.1 Lagrangian particle dispersion model
Authors: Verreyken Bert , Brioude Jérome , Evan Stéphanie
Published: April 2019

Abstract. The FLEXible PARTicle dispersion model FLEXPART, first released in 1998, is a Lagrangian particle dispersion model developed to simulate atmospheric transport over large and meso-scale distances. Due to FLEXPART's success and its open source nature, different limited area model versions of FLEXPART were released making it possible to run FLEXPART simulations by ingesting WRF (Weather Research Forecasting model) or MM5 (meso-scale community model maintained by Penn State university) meteorological fields on top of the ECMWF (European Centre for Medium-Range Weather Forecasts) and GFS (Global Forecast System) meteorological fields. Here, we present a new FLEXPART limited area model that is compatible with the AROME mesoscale meteorological forecast model (the Applications of Research to Operations at Meso-scale model). FLEXPART-AROME was originally developed to study meso-scale transport around La Réunion, a small volcanic island in the South West Indian Ocean with a complex orographic structure which is not well represented in current global operational models. The AROME vertical hybrid sigma grid is projected on the Cartesian terrain following FLEXPART grid. We present new turbulent modes in FLEXPART-AROME. They differ from each other by: dimensionality, mixing length parameterisation, turbulent transport constraint interpretation and a novel time-step configuration. Performances of new turbulent modes are compared to the ones in FLEXPART-WRF by testing the conservation of well-mixedness by turbulence, the dispersion of a point release at the surface and the marine boundary layer evolution around Reunion island. An adaptive time step for the vertical turbulent motions has been implemented to improve conservation of well-mixedness in the model.
Antecedent wetness and rainfall information in landslide threshold definition
Authors: Zhao Binru , Dai Qiang , Han Dawei , Dai Huichao , Mao Jingqiao , Zhuo Lu
Published: April 2019

Abstract. For rainfall-induced landslides, their occurrence is attributed to both the antecedent wetness condition and the recent rainfall condition. However, when defining rainfall thresholds for the landslide occurrence, these two types of information have been used incompletely or implicitly, which may affect the threshold's predictive capability. This study aims to investigate how to make a better use of these two types of information in the landslide threshold definition. Here four types of thresholds are proposed, by including different variables that are responsible for landslide occurrences, these thresholds could represent different cases, like whether to include the antecedent wetness information or whether to consider the recent rainfall condition explicitly. The predictive capability of these thresholds is then compared crossly with the help of the receiver operating characteristic (ROC) approach. We carry out this study in a northern Italian region called Emilia-Romagna. Results show that the antecedent wetness condition plays a crucial role in the occurrence of rainfall-induced landsides. It is beneficial for the threshold's predictive capability to explicitly include the antecedent wetness information and the recent rainfall in the definition of landslide thresholds. When including soil moisture information in landslide threshold, the reliability of the soil moisture measurement is a key factor affecting the threshold's prediction performance.
La dignidad humana como límite al ius puniendi. La jurisprudencia del tribunal constitucional de Chile
Authors: Ovalle Bazán Marcelo Ignacio
Published: April 2019

En este artículo se expone la jurisprudencia del Tribunal Constitucional de Chile en materia de dignidad humana con valor fundamental del orden constitucional chileno, y la manera como lo instituye con un límite al ius puniendi estatal. Se exponen textos doctrinales, tanto nacionales como extranjeros, en torno a la noción de dignidad humana y su forma de incorporación en los ordenamientos constitucionales, específicamente en la Constitución chilena. Del mismo modo, se analiza la jurisprudencia del Tribunal, para indagar la idea de dignidad humana que posee, y la manera y los alcances en su aplicación. El Tribunal considera la dignidad humana como una condición intrínseca del ser humano, de la cual se colige un deber de respeto y de consideración, principalmente del Estado. La circunstancia del reconocimiento constitucional de la dignidad lleva a estimarla como la base del orden político y social en el contexto de un Estado democrático de derecho, de lo cual se derivan y concretan en el orden del derecho punitivo una serie de principios, como la presunción de inocencia, el principio non bis in idem, el principio de culpabilidad y el de proporcionalidad de las penas, los cuales necesariamente limitan el derecho penal subjetivo del Estado.

La cuestión de las fuentes del derecho es objeto de permanente preocupación en el ámbito de la doctrina jurídica. Dentro de esta, el valor de la jurisprudencia es un tópico polémico, especialmente en el sistema continental y de modo particular en el ordenamiento jurídico cubano. El presente artículo se enfoca en fundamentar el carácter de fuente formal de la jurisprudencia, que implica su obligatoriedad, lo cual contribuiría significativamente a la uniformidad de la actividad judicial y la seguridad jurídica. Para el alcance de este objetivo se formulan ciertas condiciones –denominadas de validez formal–, en el contexto de justificación del derecho interno, en tanto posibles referentes ante las necesarias modificaciones normativas y en sede judicial, que conduzcan al efectivo reconocimiento de la jurisprudencia como fuente. En esta dirección quedan planteados los principales resultados. El análisis se llevó a cabo con los métodos de síntesis, histórico y comparado, así como la consulta de expertos.
Mapping McCarthy in the Age of Neoconservatism, or the Politics of Affect in The Road
Authors: Holloway David
Published: April 2019

This article suggests that in a reading environment weighted down by the neoconservative hegemony of the time, when considered at the level of affect—as politics enacted at the level of feeling, or as ideology experienced at a level that is prior to articulation in language—the act of reading The Road might well have worked for some readers as a powerful affirmation of post-9/11 neoconservatism. This suggestion that McCarthy's prose in The Road might embody, disseminate, and assist in the naturalizing of neoconservative structures of feeling is not, then, a claim about authorial intent. Rather, this article is interested in the reception of McCarthy's work, or at least the range of possible receptions by readers—the political uses, conscious or otherwise, to which contemporary readers might put McCarthy's prose—in a specific historical time and place as a metabolizing of historical experience, or lived ideology, in the form of literary fiction.
American Faerie: Medieval Fairy Lore in Cormac McCarthy's Blood Meridian
Authors: Mills Luke William
Published: April 2019

In Blood Meridian, Cormac McCarthy's first Western novel, medieval fairy lore bears on both McCarthy's description of the Mexico–U.S. borderlands and his creation of one of American literature's most outstanding characters, “the judge.” The borderlands, or Southwest, are recast as another “perilous realm” charged with spiritual significance, and the judge's Faerie-inflected inheritance gives another perspective on the nature of evil and American (and human) depravity.
The Bedazzled Eye: Cormac McCarthy, José Ortega y Gasset, and Optical Democracy
Authors: Luce Dianne C.
Published: April 2019

In a letter to Robert Coles, McCarthy paraphrases Ortega y Gasset's “Notes on the Novel,” which appears together with “On Point of View in the Arts” in The Dehumanization of Art. The latter essay proves to be McCarthy's primary source for the concept of optical democracy in Blood Meridian. McCarthy's reflection of Ortega's optical democracy challenges the idea that McCarthy sees no moral order in the world. His passage does not endorse the equivalency of all living and inanimate things but warns that the dazzling desert landscape of Blood Meridian is the terrain of moral confusion.

The Two-Volume Archetype of the Pauline Corpus
Authors: Stevens Luke J.
Published: April 2019

An extremely ancient edition of the Pauline corpus collecting 14 epistles into a pair of rolls, with Hebrews heading the second roll, arguably underlies the text and numbering in Codex Vaticanus. For such an arrangement, a plausible rationale is apparent, mainly involving considerations of length (perhaps further influenced by inclusion of 2 Peter as an epilogue). Furthermore, this lost two-volume edition can explain many difficulties surrounding the early evolution of the corpus. Transitioning to the single-volume codex format motivated the segregation of Hebrews from the public epistles into a distinct group alongside the four pastorals, with Galatians left still before the slightly longer Ephesians, and the resulting well-attested edition and its derivatives account for nearly all witnesses of the corpus. The exceptional 𝔭46 stems from an imperfect attempt to replicate this edition from a two-roll exemplar, while several distinctive features of Marcion’s Apostolicon derived independently from the two-volume edition. Both the titles of the epistles and the “in Ephesus” in Ephesians were absent in the original two-volume edition but were supplied when its contents were incorporated into a larger New Testament compilation. From this two-volume edition, likely assembled by Luke, all subsequent collections of Paul’s epistles have arguably descended.

It is estimated that over 75% of rural households in Tanzania depend on common bean (Phaseolus vulgaris L.) for daily subsistence. Recently, farmers have been increasingly looking for improved bean varieties which meet specific market demands characterized with yellow seed colour, early maturing and/or adapted to local agro-ecologies. Study focused on assessing the performance of bean varieties for agronomic traits through variety and environmental interactions by identifying high yielding, ealy maturing and market demand seed classes among the tested materials. For testing adaptability and stability, experiments were conducted in low to high altitudes for two consecutive years using randomized complete block design (RCBD) with three replicates. Eight common bean varieties KG98, Navy line 1, KATB9, SABRYT, KATB1, Lyamungu 85, JESCA and Calima Uyole were used. Absolute, matrix and pairwise ranking were used integratively for farmers’ and researcher’s assessment and selection. Participatory variety selection approach gave farmers an opportunity to assess and select varieties from a range of near finished materials in the breeding process. As part of the Farmers’ participatory variety selection process, seventeen participants as among the consumers 46% being women were selected to participate in a focused group discussion. Results revealed that, days to flowering, days to maturity and yield across the tested environments showed significant differences (p ≤ 0.05) as well as yield and diseases interactions for genotype, environment and season. Field data and farmers’ assessment data showed two varieties of KATB1 (yellow round) and KATB9 (red round) for better performance (high yield) and grain preference respectively. It showed that, early maturing; seed type and marketability varieties are highly demanded by bean farmers in Tanzania.

Many times, the thermal properties of a product are determined but their uncertainties (and, mainly, the covariance matrix) are not provided. Thus, in the simulations, it is not possible to establish a confidence band for a transient state described through the values obtained for these properties. In this article, a model was proposed to determine thermal diffusivity and convective heat transfer coefficient, providing the above-mentioned lack of information, for a product with spherical geometry during its cooling. The proposed model involved: 1) an experimental data set of the cooling kinetics in a point within the product; 2) a one-dimensional numerical solution of the heat conduction equation; 3) an optimizer based on the Levenberg-Marquardt algorithm to determine the thermal properties, their uncertainties, and the covariance between the parameters. Model was applied for determining thermal properties of strawberries, using an equivalent sphere to represent the geometry of the product, and the obtained results were compatible with the literature results.

The production of okra using seedlings is a practice increasingly used by farmers. However, this system still lacks further research involving substrates, tray types, cell volume, pest control and disease. For this it is important to determine the optimum size of the plots, in order to reduce the experimental errors and the expenses with the experiment. The objective of this work was to determine the optimum plot size for experiments involving okra seedlings produced in Styrofoam trays of 128 cells using different methods. The methods were the maximum curvature, the maximum curvature with bootstrap simulation and the maximum curvature of the coefficient of variation. The evaluated characteristics were aerial part height, stem diameter, aerial dry matter, root dry matter, total dry matter and quality of seedlings as measured by Dickson quality index. The results showed that the optimum plot size is different between the evaluated characteristics and for characteristics there is no significant difference in the optimum plot size between the three different methods. The optimum size for evaluating okra seedlings produced in Styrofoam trays of 128 cells is 10 seedlings per plot and is indicated the use of the maximum curvature method using a bootstrap simulation.

Published: April 2019

Tree/shrub based feed resources and feeding systems in Eastern Hararghe are not studied well. Therefore, a study aimed at assessing the availability of fodder trees and shrubs integrated into farming system, available feed resources, and feeding systems was made in two districts of eastern Hararghe zone, Ethiopia. A total of 268 respondents from the two districts, both from lowland and highland agro ecology, were interviewed. Sørensen’s Similarity Index was used to assess species composition in relation to agroecology. The result revealed that about 67.2% of the respondents have not integrated any fodder trees and shrubs into their farmlands whereas only 32.8% of the respondents integrated fodder trees and shrubs into their farmlands. A total of 20 fodder and non-fodder tree species were identified. Regarding tree species composition, only 46% of tree species were found in both districts, whereas about 54% of the tree species were dissimilar between the districts. The feeding system significantly varied with agroecology. Zero grazing system with stall-feeding technique is common in the highland agroecology. However, in the lowland agroecology free grazing on communal grazing area and feeding crop residue are common. Factors like inadequate extension service, lack of planting material and land scarcity has resulted in reduction of farmers’ interest to integrate fodder trees and shrubs into their farming system.

The decomposition of plant residues, the changes in the total organic carbon (TOC) and the fractions of soil organic matter (SOM) occur differently in irrigated areas. The objective of this study was to quantify the biomass production, the decomposition of cover crops residues and relate them with the changes n the content and fractions of SOM in an irrigated area of vegetable crops. Six types of cover crop treatments were evaluated: brachiaria (B); sunn hemp (S); millet (M); B + S; B + M; S + M, plus an additional treatment (native area), with 4 repetitions. The production of fresh (FB) and dry biomass (DB), the rate of plant residue decomposition, TOC, SOM fractions and the coefficient of SOM (QSOM) were quantified. It was observed that the greatest and the lowest volume of crop residues were from the B and S cover crop, respectively. The cover crops in monoculture presented great decomposition rates and short half-life when compared to mixtures of cover crop. The TOC and QSOM were great in the 0 to 0.05 m soil layer, and in the M + S cover crop mixture, when compared to the 0.05 to 0.1 m soil layer and to other cover crops. Among the SOM fractions, the humin predominated in the most superficial soil layer (0 to 0.05 m).

Een stapsgewijze vaststelling van de categorie uitwisselbare functies

De categorie uitwisselbare functies is een lastig, abstract begrip, maar van groot belang bij reorganisaties waarbij functies vervallen. Een goede vaststelling van de categorie uitwisselbare functies is bepalend voor de vraag of de juiste werknemers voor ontslag in aanmerking worden gebracht. Daarnaast vormt het de basis voor het toepassen van het afspiegelingsbeginsel. Door middel van een rechtspraakonderzoek, met als doel het opstellen van een (online) beslissysteem, is het mogelijk gebleken om de vaststelling van de categorie uitwisselbare functies stapsgewijs weer te geven.

Background: Transjugular intrahepatic portosystemic shunt system (TIPS) is a well-recognized method of treatment of symptomatic portal hypertension in patients awaiting liver transplantation. Effectiveness of the TIPS treatment in patients after liver transplantation is still not fully established. Indications for both groups of patients, with and without liver graft, are similar and include bleeding from gastrointestinal varices, ascites, pleural effusion and Budd-Chiari syndrome. Feasibility of TIPS in emergency treatment in patients after OLTx due to life threatening hemorrhage is not well described.
Materials and methods: Patients after OLTx performed using classical, non piggy-back technique had severe hemorrhages from gastrointestinal varices due to loss of grafts function. Patients were in an unstable condition, required blood transfusions on admittance and monitoring in Intensive Care Unit. TIPS were implanted urgently, after unsuccessful endoscopic treatment, as a life-saving procedure.
Results: In all cases procedure was successfully completed. The bleeding did not reoccur during postoperative course.
Conclusion: TIPS procedure appears to be justified, as a bridge to a planned retransplantation, or as a treatment of choice in patients disqualified from re-transplantation. Emergency performance of the TIPS procedure, as a treatment for acute variceal bleeding should still be considered individually for each patient and only as a procedure leading to further treatment.
MARKETING TOOLS USED BY THE SHARING ECONOMY PLATFORMS IN TOURISM: THE SPECIFIC ROLE OF PRICES
Authors: Skalska Teresa
Published: April 2019

Purpose. Analysis of the method of using price as a marketing tool on the example of selected cities with strong tourist function (empirical study); indication of other non-price ways of gaining competitive advantage (e.g. quality, scope of additional services) – based on empirical research, secondary sources and market analysis. Method. The article was based on the deductive approach and the results of the empirical study of offers placed by: 3* hotels, Airbnb hosts and Interhome in three metropolitan centres with developed tourist functions (Warsaw, Krakow, Prague). On the basis of the average price for 1 night (μ) and the product utility index (ή), the synthetic coefficient was calculated showing the price-to-utility relationship and allowing comparison of the price of services including the elements contained therein. Findings. The results of the empirical study allow to use two measures of price competitiveness assessment and the use of price as a marketing tool by selected service providers: the average price per night spent by the guest (μ) and the product utility index for the customer (ή). The research allowed to show the use of price as a tool of marketing impact in the area of sharing economy in tourism. Research and conclusions limitations. The sample contains all offers that meet the established criteria. The study fully reflects the situation in three selected metropolitan centres. Practical implications. The article has no direct practical implications, although the presented method and formulated conclusions can be used to improve price analysis tools in the area of tourism, taking into account the sharing economy. Originality. In the current research, the problem of using prices as a marketing tool in the area of sharing economy in tourism is rarely undertaken. Type of paper. The article presents both theoretical concepts and the results of empirical research.

Postrzeganie samodzielności przez uczniów klas trzecich uczących się według
koncepcji Planu Daltońskiego
Authors: Domagała Dorota
Published: April 2019

Głównym zadaniem szkoły jest wspomaganie dziecka w jego wszechstronnym rozwoju. Realizacja tego zadania wymaga indywidualnego podejścia do ucznia, uwzględnienia jego możliwości, zainteresowań, tempa rozwoju i aktywności poznawczej. Chcąc sprostać tym wymaganiom, nauczyciele poszukują rozwiązań organizacyjnych umożliwiających indywidualizację procesu dydaktycznego. Jedną z tych koncepcji, do której sięgają jest Plan Daltoński ponieważ wśród wielu jego zalet jest nastawienie na indywidualne potrzeby dziecka. Zapewnia on rzeczywiste indywidualizowanie procesu kształcenia prowadząc do samodzielnego uczenia się dzieci, co gwarantuje pomyślność uczniów w całożyciowym uczeniu się. W niniejszym artykule przedstawiono wyniki badania postrzegania samodzielności przez uczniów, którym stwarzano możliwości jej rozwijania. Dla samodzielności uczniów znaczące jest to, w jaki sposób nauczyciele określają możliwości samodzielności uczniów. To nastawienie nauczycieli może sprzyjać lub hamować naturalne dążenie dzieci do rozwijania samodzielności w różnych jej płaszczyznach. Artykuł zwraca uwagę na rolę przygotowania nauczyciela do realizacji koncepcji pedagogicznych, ponieważ realizowana powierzchownie, bez dogłębnego, szerokiego rozumienia jej zasad nie będzie przynosiła spodziewanych efektów.

The Local Aspect of Social Security – the Case of Warmia and Masuria
Authors: Chmieliński Bogdan
Published: April 2019

Social security is an element of the broadly understood state security system. A centralized approach to managing social needs does not take into account the local and regional differentiation of a population’s preferences, and, as a result, does not allocate resources in an optimal fashion. Decentralisation contributes to improving efficiency by way of more effective adaptation of public services to social needs, which is achieved by gaining a wider and deeper knowledge about the needs of local communities. Greater power of local authority bodies inspires innovative solutions and stimulates activity and competition between territorial units. It contributes to the rational allocation of resources at the disposal of local authorities, which leads to the conclusion that they are dominant with regard to exercising the social function of the state.

Authors: Płonka Bogusław
Published: April 2019

This paper is dedicated to the topic of security in the context of activities carried out by organisations. The analysis of the security-related context of the enterprises, decisions and threats that often co-occur with organisational activities is an interesting challenge for a researcher. The aspiration to ensure their own survival and undisturbed development is the basic driving force behind all organisations. In the following paper, the author explains the meaning of basic terms connected with the aforementioned issues, such as uncertainty, risk and security. The models and dimensions of control are discussed consecutively, as well as the methods and techniques utilised in risk assessment. Control and risk analysis are currently the means of counteracting threats that is most commonly used in organisations. The aim of the paper is to carry out the review of the hitherto existing research stipulations regarding the sphere of organisational security. The author points out that the problem of organisational security, treated as a core research subject, may be successfully developed and elaborated within the framework of security sciences discipline.
