The definition of requested requirements by the companies represents one of the key aspects for the entrance of new professional figures. In particular, focusing the attention on food & beverage sector, in this study two job profiles are considered: pastry chef e pastry assistant. Data for this analysis are collected by The AdeccoGroup in Italy in 2016 and 2017. The personal competencies to make capable to face the growing flexibility of the profession are object of specified request cross-sectional to more economic sectors. After a brief description of the database content, the principal objective of the research is to report the most requested requirements for the companies. Other analysis are provided to show possible relationships among these requirements and the previous experience owned by candidates. Finally, a comparison is presented about the competencies requested by the two job figures using descriptive statistics and classification techniques.

In water polo, two teams comprised of six outfield players and a goalkeeper compete for four quarters of 8 minutes' real play in a playing area of 30x20m. Each team has 30 seconds to complete an action. A frequent situation thought to be very significant to the final result of a match is the extra-man play action. After a major foul a player is sent out of play for 20 seconds. The attacking team, with a series of passes and player movements must quickly try to disrupt the defence and enable a shot. And defence has to work on coordination of movement between players so that the attack finds it difficult to score too easily. Coaches dedicate a lot of time to training their team to attack and defend in an extra-man situation. This paper investigates the issue of extra-man play actions in detail. A study is performed into data from the 2020 European men's water polo championships, whose aim is to identify whether man-up play actions have any elements that lead to a good shot, meaning a ball in the goal even if it is saved. Several characteristics were recorded on each extra-man play action, but only few of them seem to influence its outcome. This may be explained by the fact that the outcome of a play action is not only linked to the execution of a strategy, but it is influenced by factors which may not all be measured.

Log-linear, logit and logistic regression models are the most common ways of analyzing data when (at least) the dependent variable is categorical. This volume shows how to compare coefficient estimates from regression models for categorical dependent variables in three typical research situations: (i) within one equation, (ii) between identical equations estimated in different subgroups, and (iii) between nested equations. Each of these three kinds of comparisons brings along its own particular form of comparison problems. Further, in all three areas, the precise nature of comparison problems in logistic regression depends on how the logistic regression model is looked at and how the effects of the independent variables are computed. This volume presents a practical, unified treatment of these problems, and considers the advantages and disadvantages of each approach, and when to use them, so that applied researchers can make the best choice related to their research problem. The techniques are illustrated with data from simulation experiments and from publicly available surveys. The datasets, along with Stata syntax, are available on a companion website

Trying to determine when to use a logistic regression and how to interpret the coefficients? Frustrated by the technical writing in other books on the topic? Pampel's book offers readers the first 'nuts and bolts' approach to doing logistic regression through the use of careful explanations and worked out examples.

This text begins by showing how logistic regression combines aspects of multiple linear regression and loglinear analysis to overcome problems both techniques have with the analysis of dichotomous dependent variables with continuous predictors. It then examines what can go wrong with the model and how to detect and correct it.
