Current approaches to player profiling are limited in that they typically employ only a single one of numerous of available techniques shown to have utility for categorizing and explaining player behavior. We propose a more comprehensive Video Game Player Profile Framework that considers the demographic, psychographic, mental model, and behavioral modeling approaches shown to be effective for describing gamer populations. We suggest that our proposed approach can improve the efficacy of video game player profiles by grounding data-driven techniques in game analytics with the theoretical backing of demographic, psychometric, and psychographic measurements. We provide an overview of our proposed framework, discuss the usage and relevance of each component technique, and provide a proof-of-concept demonstration with archived data.

Abstract Background: We compare the health-related quality of life (QoL) of patients with incision hernias before and after surgery with two different techniques.Methods: In this prospective randomized study, the study population consisted of all patients who underwent the first surgical incisional hernias repair during the 1-year study period. Patients who met the criteria for inclusion in the study were randomized into two groups: the first group consisted of patients operated by an open Rives sublay technique, and the second group included patients operated by a segregation component technique. The change in the quality of life before and 6 months after surgery was assessed using two general (Short form of SF-36 questionnaires and European Quality of Life Questionnaire - EQ-5D-3L), and three specific hernia questionnaires (Hernia Related Quality of Life Survey-HerQles, Eura HS Quality of Life Scale - EuraHS QoL, and Carolinas Comfort Scale – CCS).Results: A total of 93 patients were included in the study. Patients operated on by the Rives technique had a better role physical score before surgery, according to the SF-36 tool, although this was not found after surgery. The postoperative Qol measured with each scale of all questionnaires was significantly better after surgery. Comparing two groups of patients after surgery, only the pain domain of the EuraHS Qol questionnaire was worse in patients operated by a segregation component technique.Conclusion: Both techniques improve the quality of life after surgery. Generic QoL questionnaires showed no difference in the quality of life compared to repair technique but specific hernia-related questionnaires showed differences.

Internationalization of higher education is a priority in the European education policy. Since it began in 1987/1988, the world’s most successful student mobility programme, the Erasmus programme, has provided over three million European students with the opportunity to go abroad and study at a higher education institution. Aiming to speed up this trend, for the next long-term EU budget 2021-2027, the European Commission has proposed to double funding for Erasmus to EUR 30 billion. In this way, it will make it possible to support up to 12 million people between 2021-2027. However, learning mobility barriers still exist and the shares of study abroad participants vary widely across Member States. Within this context, the aim of this contribution is to investigate the motivations and concerns about the experience abroad of 1272 students of a medium size Italian university – the University of Bergamo – that apply for an Erasmus+ or Extra-EU Program. To analyse the data collected by an on-line survey we used the Principal Component Technique. 


The current work expects to decide the attributes of compression of the (Magnesium composite) AZ 91E-Zro2-Fly Ash Hybrid Metal Matrix utilizing the conventional explanatory strategy and limited component technique. Fly ash and ZrO2 taken as equal weight proportions, composites are fabricated by means of a vortex method under the path of stir casting. The density and fracture toughness were found experimentally, the experimental density was decreased compare to the theoretical density, but the density is increased slightly for composites compare to the base material. The fracture toughness is decreased for composites compare to the base material; this is due to the improvement of the grains by adding strengthening molecules. The compressive strength was decreased by decreasing of the height of the deformation in percentage for base material and the composites of H/D 1.0 and 1.5. The compressive strength is high for the composites compare to the base material even the density of the composite is little bit high, hence suggested that composite system gives the better compressive strength results

The aim of this study was to employ the principal component technique to physiological data and environmental thermohygrometric variables correlated with detection of clinical and subclinical mastitis in dairy cattle. A total of 24 lactating Girolando cows with different clinical conditions were selected (healthy, and with clinical or subclinical mastitis). The following physiological variables were recorded: udder surface temperature, ST (°C); eyeball temperature, ET (°C); rectum temperature, RT (°C); respiratory frequency, RF (mov. min-1). Thermohygrometric variables included air temperature, AirT (°C), and relative humidity, RU (%). ST was determined by means of thermal images, with four images per animal, on these quarters: front left side (FL), front right side (FR), rear right side (RR) and rear left side (RL), totaling 96 images. Exploratory data analysis was run through multivariate statistical technique with the employment of principal components, comprehending nine variables: ST on the FL, FR, RL and RR quarters; ET, RT; RF, AirT and RU. The representative quarters of the animals with clinical and subclinical mastitis showed udder temperatures 8.55 and 2.46° C higher than those of healthy animals, respectively. The ETs of the animals with subclinical and clinical mastitis were, respectively, 7.9 and 8.0% higher than those of healthy animals. Rectum temperatures were 2.9% (subclinical mastitis) and 5.5% (clinical mastitis) higher compared to those of healthy animals. Respiratory frequencies were 40.3% (subclinical mastitis) and 61.6% (clinical mastitis) higher compared to those of healthy animals. The first component explained 91% of the total variance for the variables analyzed. The principal component technique allowed verifying the variables correlated with the animals' clinical condition and the degree of dependence between the study variables.

The fast-growing urbanization has contributed to the construction sector becoming one of the major sectors traded in the world stock market. In general, non-stationarity is highly related to most of the stock market price pattern. Even though stationarity transformation is a common approach, yet this may prompt to originality loss of the data. Hence, the non-transformation technique using a generalized dynamic principal component (GDPC) were considered for this study. Comparison of GDPC was performed with two transformed principal component techniques. This is pertinent as to observe a larger perspective of both techniques. Thus, the latest weekly two-years observations of nine constructions stock market price from seven different countries were applied. The data was tested for stationarity before performing the analysis. As a result, the mean squared error in the non-transformed technique shows eight lowest values. Similarly, eight construction stock market prices had the highest percentage of explained variance. In conclusion, a non-transformed technique can also present a better resultoutcome without the stationarity transformation.
