Polish Jokes about Americans
2004
The objective of the present paper is to analyze the character of Polish jokes about Americans and to find out what these jokes say about Poles. The latter question results from the assumption that stereotypes reveal more about those who propagate them than about those who allegedly represent particular traits. The popularity of Americans is a certain novelty in contemporary Polish jokes and this fact could be interpreted as another element in the processes of so-called McDonaldization. The texts are presented by the chronology of events they refer to. Americans are perceived by Poles as the enemies of the Russians, and so as a positive protagonist, a symbol of the high standard of living a…
Financial Evaluation of SLA-based VM Scheduling Strategies for Cloud Federations
2017
In recent years, cloud federations have gained popularity. Small as well as big cloud service providers (CSPs) join federations to reduce their costs, and also cloud management software like OpenStack offers support for federations. In a federation, individual CSPs cooperate such that they can move load to partner clouds at high peaks and possibly offer a wider range of services to their customers. Research in this area addresses the organization of such federations and strategies that CSPs can apply to increase their profit.In this paper we present the latest extensions to the FederatedCloudSim framework that considerably improve the simulation and evaluation of cloud federations. These si…
A Comparative Analysis of Agile Maturity Models
2013
Agility has increased in popularity in software development. It is believed to reduce time to market, improve product quality, and increase customer value. After some years from adoption, organizations start questioning how they are doing in the application of agile values, principles, and practices. Have they really obtained the benefits the agile approach promises? How could they improve their agile processes? For these kinds of situations, several agile maturity models have been suggested. This chapter makes a comparative analysis of eight agile maturity models, based on criteria such as purpose, domain, conceptual and theoretical backgrounds, approach, structure, use, and validation. We…
Heterogeneity in general practitioners’ preferences for quality improvement programs: a choice experiment and policy simulation in France
2016
International audience; Despite increasing popularity, quality improvement programs (QIP) have had modest and variable impacts on enhancing the quality of physician practice. We investigate the heterogeneity of physicians’ preferences as a potential explanation of these mixed results in France, where the national voluntary QIP – the CAPI – has been cancelled due to its unpopularity. We rely on a discrete choice experiment to elicit heterogeneity in physicians’ preferences for the financial and non-financial components of QIP. Using mixed and latent class logit models, results show that the two models should be used in concert to shed light on different aspects of the heterogeneity in prefer…
A Unified Approach to Measuring Accuracy of Error Indicators
2014
In this paper, we present a unified approach to error indication for elliptic boundary value problems. We introduce two different definitions of the accuracy (weak and strong) and show that various indicators result from one principal relation. In particular, this relation generates all the main types of error indicators, which have already gained high popularity in numerical practice. Also, we discuss some new forms of indicators that follow from a posteriori error majorants of the functional type and compare them with other indicators. Finally, we discuss another question related to accuracy of error indicators for problems with incompletely known data.
Limited Usefulness of Capture Procedure and Capture Percentage for Evaluating Reproducibility in Psychological Science
2018
In psychological science, there is an increasing concern regarding the reproducibility of scientific findings. For instance, Replication Project: Psychology (Open Science Collaboration, 2015) found that the proportion of successful replication in psychology was 41%. This proportion was calculated based on Cumming and Maillardet’s (2006) widely employed capture procedure (CPro) and capture percentage (CPer). Despite the popularity of CPro and CPer, we believe that using them may lead to an incorrect conclusion of (a) successful replication when the population effect sizes in the original and replicated studies are different; and (b) unsuccessful replication when the population effect sizes i…
Aggression in television programs in Finland
1993
A detailed coding system was constructed to study the frequency and salience of aggression in TV programs broadcast on Finnish television. Salience of aggression was measured by the brutality index which consisted of ratings concerning the 1) program context, 2) seriousness, 3) justification, and 4) dramatization of aggressive acts. When compared to previous studies of TV-violence, the rate of aggression in Finnish TV was moderate with 3.5 aggressive acts per program hour. Only 14% of aggressive acts portrayed brutal aggression, which was mostly seen in fictional films and serials. A clear 9 pm watershed was not seen in Finland, since aggressive acts were distributed quite evenly during the…
Reporting Empirical Research in Global Software Engineering: A Classification Scheme
2008
Increased popularity of global software engineering (GSE) has resulted in quite a number of research and industrial studies. As the area matures, an increased focus on empirically supported results leads to a greater potential impact on future research and industrial practice. However, since GSE scenarios are diverse, what works in one context might not directly apply in another. Thus it is necessary to understand, how GSE-related empirical findings should be reported to be useful for practitioners and researchers. Furthermore, itdasias important to summarize progress and get the big picture of published research to identify gaps and commonalities. In this paper we analyze differentiating f…
Effects of school climate and teacher self-efficacy on job satisfaction of mostly STEM teachers: a structural multigroup invariance approach
2020
Abstract Background Identification and retention of effective teachers in STEM education play cardinal roles in teacher recruitment exercises worldwide. Studies on factors that characterize effective teachers have therefore gained popularity in recent times. Teacher self-efficacy, job satisfaction and school climate are among other factors that have attracted global attention. Thus, proper understanding of the relations between these factors is equally important. The purpose of this study is to validate and cross-validate a model of direct/indirect effects of school climate and teacher self-efficacy on job satisfaction. Results The data used for the current study are extracted from a public…
The Essence of Dynamic Capabilities and their Measurement
2016
The growing popularity of explaining firm performance through dynamic capabilities has motivated plenty of conceptual development in the field. However, empirical approaches to measuring dynamic capabilities have so far not been under comprehensive scrutiny. The authors; purpose is to assess the extent to which different ways of measuring dynamic capabilities in quantitative studies correspond to the theoretical essence of the concept, and develop recommendations for future research. They find that four types of operationalizations have been used: (1) managers’ evaluations; (2) financial data; (3) company's experience, actions and performance; and (4) managers’ or employees’ experience, act…
