Evaluation of socio-organizational environment of ERP projects

The paper presents the method supporting analysis and evaluation of organizational and socio-psychological issues of ERP projects. It is based on socio-organizational implementation determinants (SOID) model. The aim of the study is to assess the usefulness of this model for evaluation - and consequently improvement - of this critical aspects of ERP implementation projects. SOID consists of over 160 elements influencing the effectiveness of ERP implementation projects. They all deal with human aspects of system projects and can be embraced in three categories: enterprise culture, project management and knowledge management. The methodology of SOID application is outlined. Then, based on a case study of Polish company, possible utilization of its results for project development sake is described

Simulations of Ocean Circulation Under an Ice-Shelf: Problem Feasibility Study Using Non-Hydrostatic Unified Model of the Ocean (NUMO)

Antarctic ice-cover extends from the ice-cap on the continent (ice-sheet) into the surrounding ocean forming floating ice-shelves. The interaction of ice-shelves and ocean underneath (in the so-called ice-shelf cavity) controls the rate at which the ice is exported from the ice-sheet to the ocean, which directly contributes to sea-level rise. The ocean circulation underneath Antarctic ice-shelves is poorly understood and is one of the focal points of worldwide climate modeling efforts. In this work, we are conducting a feasibility study of deploying a new ocean circulation model NUMO to an ice-shelf cavity circulation problem. We are testing the performance of the model on a simplified cavity geometry, with a particular focus to the area close to the grounding line. The feasibility study involves measuring the time it takes the model to produce a 2-week simulation given the spatial resolution used, the order of the numerical scheme, and the number of processors of Boise State’s R2 cluster used for the simulation. The results of this study will be used to improve the performance of the NUMO model

Convection Modeling of Ice-Ocean Interaction

Ice-ocean interaction is an essential component of the Earth\u27s climate system and is one of the key challenges in climate modeling. It has profound consequences for the ocean, such as transforming the water masses through the melting or freezing of ice. The present-day climate models cannot satisfactorily resolve the fine-scale process at an ice face, especially the plume of an order of 10 m that rises at the ice face. We investigate the melting and the plume when vertical ice dissolves into seawater through convection under Antarctic Ocean conditions using the Non-hydrostatic Unified Model of the Ocean (NUMO), a high-resolution model to resolve the plume at the ice face. Three coupled equations have been solved for the ice interface\u27s temperature, salinity, and melting rate. The seawater temperature of 2.3°C and salinity of 35psu are used for the simulation. We saw that the ice melting is significantly governed by heat and salt fluxes to the interface and obtained temperature profiles and velocity components v and w in y and z directions, respectively, in agreement with those obtained in Gayen et al. (2016) with an appropriate choice of the pressure coefficient for the liquidus temperature and seawater viscosity. In this talk, we will present and discuss the results from NUMO and present some of the challenges

Gases in the near-surface zone of the reclaimed Barycz municipal waste landfill – a case study from southern Poland

The formation of biogas at municipal landfills and the significant emission of greenhouse gases from these facilities into the environment were the main reasons for analyzing the molecular composition of soil gas in the near-surface zone at the reclaimed part of the Barycz municipal waste landfill. The relations between the studied components (methane, carbon dioxide, light hydrocarbons and non-hydrocarbon components) and impact of the magnitude of recorded concentrations of methane and carbon dioxide on their emission to the atmosphere were evaluated. Two profiles were determined, along which 41 soil and landfill gas samples were taken at 20-meter intervals. At the same time, emissions were measured at each sampling point using a static chamber with a portable fluxometer. Chromatographic analysis showed that the concentrations of methane and carbon dioxide fluctuated in the ranges: 2.1 ppm – 76 vol% and 0.04 ppm – 11 vol%, respectively. Relatively high concentrations of these gases were determined at many of the measurement points, and this was particularly evident at the A-A’ profile, indicating stronger biochemical processes in this part of the landfill, or lateral migration of methane from the neighbouring stage II of the landfill, where biogas extraction is currently taking place. In addition, significant correlations between methane, carbon dioxide, and oxygen were demonstrated, indicating ongoing methane fermentation processes. Based on the study, it can be concluded that the southern part of the A-A’ profile is an optimal place to locate a degassing well from which biogas production could be used. However, the research is only preliminary and, it will be necessary to extend the soil gas tests before the final decision on the location of the well is made. Moreover, it has been shown that the concentrations of methane and carbon dioxide measured at points located outside the landfill were low. This means that generated biogas probably does not migrate beyond the boundaries of reclaimed waste landfill, but this will need to be confirmed by performing additional soil gas tests inside and outside the landfill area. The preliminary assessment of the effectiveness of the reclamation carried out was confirmed by the negligible values of the measured methane and carbon dioxide emissions on the surface

Crisis-resistant tourists : a study of hotel online reviews in the times of Covid-19

Introduction. Tourists traveling in the times of crisis have a higher tolerance for risk and can be called ‘crisis-resistant’. The fact that they are ready to travel even if it is burdened with additional stress and obstacles makes them a valuable market segment for hoteliers, which is worth striving for particularly in the current pandemic situation. The research aims at better understanding of contemporary ‘crisis-resistant’ tourists through in-depth analysis of electronic Word of Mouth (eWOM). Material and methods. A web scrapping method was applied to acquire eWOM content posted by tourists traveling in the times of Covid-19. A total of 1239 reviews from 455 hotels were analyzed. Six hypotheses were tested with the use of T Test and Chi Square test. Results. The type of travel and the month of travel did not influence the frequency of coronavirus mentions. Similarly, reviews relating to COVID-19 did not vary in score nor in frequency of managerial replies. However, mention of coronavirus influenced the length of the review and its helpfulness. Conclusions. Crisis-resistant tourists treat issues related to the pandemic (includ ing some in-hotel regulations and restrictions) as any other aspects of the hotel performance and accept them. Interestingly, those aspects do not negatively influence the total evaluation of the hotel, which may suggest that such tourists have already adapted to all the pandemic-induced burdens. At the same time, hotel managers fail to respond timely and adequately to nega tive comments, which seems to be of the key importance in such a situation
