Day Of The Week

The frequency of births by day of the week has been reported by several studies without a formal statistical analysis. Births occurring on weekends have been consistently found to be less frequent than births on weekdays. In this study, we compared different statistical methods to assess the effect of the day of the week on the timing of births. We employed two statistical methods, two-way ANOVA and two-way Friedman's test, to analyze the daily variations of 222,735 births from 2005 to 2007 in Harris County, Texas. Both of the statistical tests indicated that births were not uniformly distributed by day of the week. Pairwise comparisons demonstrated that the births occurring on weekends were significantly less frequent than births occurring on weekdays. Our study together with other empirical studies would provide useful information for improving hospital management and the health of infants and their mothers.

Tools And Methods

Purpose. The aim of the study was to discuss the use of tools and methods of statistical analysis, as well as forms of graphic presentation of results obtained in articles published in “Folia Turistica” during the last 30 years of its history. Method. The basic method was a review of all articles in terms of the use of statistical methods applied in scientific papers published in “Folia Turistica” in the years 1990 - 2018 (volumes 1- 49). Findings. Out of 486 articles published in 49 volumes of “Folia Turistica” from 1990-2018, 31% used statistical tools and methods. The graphic presentation of analysis of results can be found in 78 articles (including 12 publications with prepared maps), the use of statistical tests in 35 articles, and the use of multi-dimensional statistical methods in 28 articles. An important part of the works are methodological publications. The authors used statistical parametric and non-parametric tests, linear and non-linear regression models, taxonomic and factor analysis and (in individual cases) relatively rare tests, including those related to spatial analyses (I-Moran and Isard coefficient). Research and conclusions limitations. The work concerns the use of statistical tools and methods in scientific articles in “Folia Turistica” issue No. 1-49. In some works, there was no verification of the applicability assumptions of selected statistical tools or justification for their selection, or the purposes of the research were too general. Practical implications. The indicated tools and methods of statistical analysis may be inspiration for authors and readers of scientific papers in the preparation of numerical data and forms of their presentation.

The purpose of article is to identify opinions on the preferred environment of cooperation between final purchasers and offerors, and to determine the benefits that the purchaser may derive from this cooperation depending on the environment in which the cooperation takes place. To prepare the theoretical part of the article, cognitive-critical analysis of the world literature on marketing, market behavior, and management was used. The results of this analysis indicate a cognitive and research gap in the area of considerations about the environment of cooperation between final purchasers and offerors and the importance of this environment in relation to the expected benefits. In order to reduce the identified gaps, empirical studies were conducted among Polish adult representatives of final purchasers, in which the survey method was used to collect primary data. The primary data collected was subjected to statistical analysis using various methods (average score analysis, exploratory factor analysis, cluster analysis) and statistical tests (e.g., the Kruskal–Wallis test). The results of the statistical analysis made it possible to verify the formulated research hypotheses. It was found, inter alia, that the majority of respondents considered offline and online environments to be equally useful for cooperation between final purchasers and offerors. More than half of the respondents appreciated benefits related to personal development (through gaining new knowledge, skills, and experience), social development (through building relationships with other people), and creating offers better suited to purchaser expectations due to influencing their shape. The preferred environment of cooperation with offerors was a feature differentiating opinions on the benefits of the following: Personal development, social development, and the possibility of obtaining an offer that better meets the expectations of purchasers. This feature did not differentiate benefits related to psychological development and material benefits. Conclusions drawn from the research have a high cognitive value (increasing knowledge about the behavior of active purchasers) and practical value (helping managers to create conditions favorable for cooperation between offerors and final purchasers).

Background: Many pediatric studies describe the association between biological parameters (BP) and severity of sickle cell disease (SCD) using different methods to collect or to analyze BP. This article assesses the methods used for collection and subsequent statistical analysis of BP, and how these impact prognostic results in SCD children cohort studies. Methods: Firstly, we identified the collection and statistical methods used in published SCD cohort studies. Secondly, these methods were applied to our cohort of 375 SCD children, to evaluate the association of BP with cerebral vasculopathy (CV). Results: In 16 cohort studies, BP were collected either once or several times during follow-up. The identified methods in the statistical analysis were: (1) one baseline value per patient (2) last known value; (3) mean of all values; (4) modelling of all values in a two-stage approach. Applying these four different statistical methods to our cohort, the results and interpretation of the association between BP and CV were different depending on the method used. Conclusion: The BP prognostic value depends on the chosen statistical analysis method. Appropriate statistical analyses of prognostic factors in cohort studies should be considered and should enable valuable and reproducible conclusions.

The Nordic countries are often considered as remarkably exceptional in terms of the proenvironmental behavior of their citizens and also as forerunners in environmental policies. However, very few empirical studies have been done at the aggregated level about how the Nordics compare to other countries. The article addresses this knowledge gap and analyzes the Nordic region in terms of willingness to make economic sacrifices, proenvironmental attitudes and behaviors. Data (N = 5877) from the environment module of the International Social Survey Program (ISSP) are utilized, with nonparametric statistical tests and multinomial logistic regression employed—wherein, emphasis is placed on the regression models for willingness as dependent variables as analysis of the first order, with attitudes, behaviors and sociodemographic variables as part of second order analysis. The findings reveal that the region’s higher levels of willingness, attitudes, and behaviors become more salient when compared to third countries. People in the Nordic region who are ‘neither willing nor unwilling’ to protect the environment can be considered as distinct, and should not be arbitrarily lumped within the categories of the ‘unwilling’ or ‘willing’ respondents. These insights allow for a deeper understanding of peoples’ willingness and the relationships to respective attitudes and behaviors beneficial towards engaging the acceptability of extant environmental policies.

Research Gap

The aim of this article was to identify the role of good mutual relationships with offerors for final purchasers, as well as define the meaning of the perception of offerors in the scope of listening to purchasers’ opinions and profiting from purchasers’ readiness to cooperate for the specificities of the prosumeric activity. A deep analysis of the world literature was used to prepare the theoretical part of this paper. The results of this analysis confirm the existing cognitive gap and research gap regarding mentioned aspects, including energy market. Empirical studies were conducted to reduce identified gaps. The survey method was used to collect primary data. The collected data were subjected to quantitative analysis, during which statistical analysis methods and tests were applied (Pearson chi-square independence test, V-Cramer factor analysis, Kruskal–Wallis test (KW), and exploratory factor analysis). The results of the statistical analysis and testing allowed the three research hypotheses formulated to be checked. Between the significance of good relationships with offerors and their perception, a statistically significant dependence was identified for all groups of offerors. The perception of offerors was a feature differentiating respondents’ opinions about the significance of good relationships with offerors for the two following groups: producers and traders. Additionally, the perception of offerors was a feature differentiating forms of prosumeric activity of respondents only for three interpurchase behaviors. The results obtained have a visible cognitive and applicability value. They contribute to the theory of marketing, as well as possibly facilitating the formation of good mutual relationships between offerors (including offerors of energy) and final purchasers as key partners cooperating with offerors in the marketing process. The approach presented in this paper has not been studied and analyzed so far, either in theoretical or in practical terms. This fact confirms its originality and value.

The Impact

The aim of this article was to determine the significance of modern marketing communication channels used in the process of shaping the external image of an enterprise as an employer. An analysis of the world literature on marketing, management, marketing communication and human resource management was used to prepare the theoretical part. The results of the analysis indicate a cognitive and research gap regarding the use of modern communication channels for building the external image of an enterprise in the role of an employer. In order to reduce the gap, empirical studies were conducted among young Polish potential employees, in which the survey method was used to gather primary data. The collected data were subjected to statistical analysis, during which the following methods and statistical tests were applied: the analysis of average values, exploratory factor analysis, Kruskal–Wallis test (KW), Pearson chi-square independence test and V-Cramer coefficient analysis. The results of the analyses conducted indicate, inter alia, that statistically significant diversity was identified in the case of non-professional media in terms of respondents’ opinions on whether the employer’s image created by modern media is better than the employer’s image created on the basis of classical marketing communication channels. In the case of professional and non-professional media, the age of the respondents was not a differentiating feature. Moreover, neither for professional media nor for non-professional media were statistically significant dependencies identified between respondents’ opinions on the impact of actions undertaken by enterprises on shaping their positive external image as an employer and respondents’ opinions on whether the employer’s image created on the basis of modern marketing communication channels is more beneficial than the employer’s image created on the basis of classical marketing communication channels. The results obtained on the basis of the research have a cognitive and applicability value, characterized by originality. Until now, the importance of using modern marketing communication channels in shaping the employer’s external image has not been analysed. This also applies to enterprises operating on the energy market.

Abstract MOOC appearance has produced, in a first phase, more discussions than contributions. Despite pessimistic opinions or those catastrophic foreseeing the end of the classic education by accepting MOOC, the authors consider that, as it is happening in all situations when a field is reformed, instead of criticism or catastrophic predictions, an assessment should be simply made. MOOC will not be better or worse if it is discussed and dissected but can be tested in action, perfected by results, or abandoned if it has no prospects. Without testing, no decision is valid. A similarity between the MOOC appearance and the appearance of the idea of flying machines heavier than air can be made. In the flight case, the first reaction was a strong negation (including at Academies level) and only performing the first independent flight with an apparatus heavier than air has shifted orientation from denial to contributions. So, practical tests clarified the battle between ideas. The authors of this article encourage the idea of testing–assessment and, therefore, imagined and proposed one software for quickly assess whether MOOC produces changes in knowledge, by simply transferring courses from ‘face-to-face’ environment into the virtual one. Among the methods of statistical analysis for student behavioral changes was chosen the Keppel method. It underpins the assessment method of this work being approached using both the version with one variable and also with three variables. It is intended that this attempts to pave the way for other series of rapid assessment regarding MOOC effects (using other statistical methods). We believe, that this is the only approach that can lead either to improve the system or to renunciation.
