While this provides flexibility, it also presents the challenge of dirty data, which includes spelling errors, missing series titles, and unofficial yet popular abbreviations inputted by the user. The manual resolution of these anomalies is impractical and resource-intensive. To address this issue, a fuzzing string machinebased game mapping system was designed and evaluated using 1,096 game titles input by users. GMap-R, a real-time autocomplete game title system to aid runtime user entry, was also created and evaluated using 150 game titles provided by 30 participants, each of whom listed their five favorite games twice. With GMap-R, the correct mapping percentage increased to 98.67%. These preliminary evaluations indicate that the proposed strategy can significantly enhance the cleansing and input of game titles' free-form text. In turn, this helps to conserve resources when obtaining unsupervised data through online studies. CCS CONCEPTS • Information systems → Recommender systems.

Research paper thumbnail of Preliminary Study of the Performance of the miniPXI when Measuring Player Experience throughout Game Development

In the field of games, the miniPXI is such a validated short version of the player experience inventory (PXI), containing 11 single items to measure 11 different PX-related constructs. Previous validations of the miniPXI were carried out in an experimental setting with existing, fully finished games. In this study, we conduct a preliminary investigation of the potential of miniPXI to evaluate prototypes during game development. We explore differences in PX across two iterations of nine games prototypes, based on input from 16 participants. Findings suggest that the miniPXI is capable of detecting differences between the two prototype versions. In addition, at the level of individual games, the miniPXI is effective at identifying differences in nearly all PX dimensions. However, we also find limited use for the single enjoyment item, and suggest that including alternative measures such as the Net Promotor Score may be more useful. Overall, this work suggests that the miniPXI has the potential to evaluate different iterations of game prototypes, starting from the earliest stages of game development.

However, having too many questions in surveys prevents wider uptake among GUR professionals because of games' rapid production cycles. To address this issue, we present the miniPXI---an eleven-item measure of the popular Player Experience Inventory (PXI)---providing single items for each of its eleven constructs. To develop the scale and examine its reliability and validity, we present three studies, conducted with 15 experts and 628 digital game players across continents. In the first survey study (n=366, 15 experts), single items were selected. In a second survey study (n=232), we explored reliability and validity of the single-item scale. Participants completed both full and single-item (SI) variants in three days. In the last study (n=30), we established the validity and sensitivity via an experimental evaluation of two games. The results are nuanced; SI reliability estimates for PXI cons...

Based on the Player Experience Inventory (PXI), it provides detailed information about the baseline theoretical model and supports a layman analysis of PXI questionnaire data. Moreover, it provides an interactive feature to explore benchmark PXI data of existing game evaluations. This helps a GUR expert to explore and compare their own game data to data from a relevant genre or specific game.

User friendliness of the semantic web need to be focused and improved in order to increase the adoptability. This paper aims to identify some usability related problems in Semantic Web. Usability of some keyword and form based tools and their limitations are being discussed. Results and findings of a usability survey of the tool are presented. Possible improvements for successful system are also being discussed.

Chronic and systemic inflammation plays a major role in the development of these diseases, and there are striking similarities between the molecular and inflammatory pathways in psoriasis and atherosclerosis. In a single-centre, cumulative, prospective registry study of 347 hypogonadal men (total testosterone ≤12.1 nmol l À1), fifteen men with psoriasis could be studied. Upon testosterone administration, the skin disease improved considerably. Scores on the Psoriasis Area and Severity Index and Physician Global Assessment for Psoriasis showed significant improvement for the first 24 months. Thereafter, these improvements were sustained. Upon testosterone treatment, C-reactive protein declined significantly. There were significant improvements of obesity and of lipid profiles. Adipose tissue is now regarded as a source of inflammatory factors. These preliminary results deserve to be studied in a specifically designed study to investigate the effects of testosterone on psoriasis and its associated immunopathology.

Also systolic and diastolic blood pressure improved significantly. All changes were more pronounced with increasing obesity grade. Cohort 2: Weight decreased progressively from 110.37 ± 14.28 to 89.38 ± 9.33 by 21.36 ± 0.73 kg. Waist circumference decreased from 109.34 ± 7.97 to 99.89 ± 6.48 by 11.34 cm. Fasting glucose decreased from 113.45 ± 14.53 to 95.93 ± 2.56 mg/dl, HbA1c from 8.02 ± 0.86 to 5.9 ± 0.45% (p < 0.0001 for all). At baseline, 11% of patients were within an HbA1c target of ≤7%, 4% of patients within ≤6.5%; all patients completing 7 years of treatment had an HbA1c ≤7%. And, except one patient, all had reached an HbA1c ≤ 6.5%. Conclusions: Restoring testosterone levels to normal in hypogonadal obese men produced sustained and clinically meaningful improvements of obesity, the metabolic syndrome, and, in men with T2D, improved metabolic control. Diagnosing and treating testosterone deficiency in these categories improves their condition significantly, and deserves to be considered.

Database searches were methodically conducted across six data bases. The inclusion criteria specified the need for empirical research, and publication dates ranged from 1997 to 2017. The article begins by setting the scene for the systematic review, exploring historical and international practices related to multiage complexities and terminology. Curriculum and pedagogical practices are explored to identify key advantages and disadvantages associated with a multiage approach in small school contexts.
