Recently, as in the other sciences, also in Statistics quality is calling more attention. In this article the Authors consider the methodological peculiarities of electoral polls carried out in Italy in the last eight years and published on the web site of Department for Information and Publishing of Presidency of the Council of Ministers, according to the Authority Regulation. Particularly, they analyze the electoral polls considering how they respect the major quality dimensions and propose to this aim a study conducted on the basis of analysis scenarios. The results show that, even many gaps in terms of quality respect and information completeness persist again, quality culture is becoming a general rule for many opinion polls companies, encouraging in public opinion a greater knowledge of its importance.Key words: Quality; Completeness; Polls.Parole chiave: Qualitŕ; Completezza; Sondaggi.

Metadehumanization, the perception that members of an outgroup dehumanize your group, has been found to exacerbate intergroup conflict by inspiring reciprocal dehumanization of the offending outgroup. Moreover, metadehumanization is distinct from metaprejudice (i.e., the perception that an outgroup hates your group). Given the mutual animosity reported in public opinion polls toward the other side, we believed US–Russia relations would be a worthwhile context in which to extend this model. Therefore, we measured Americans’ levels of metadehumanization and metaprejudice of Russians to determine the association between these perceptions and their hostility toward Russians (Study 1). In this novel intergroup conflict, metadehumanization remained a consequential predictor of outgroup hostility over and above metaprejudice, suggesting that it can exacerbate a broader range of intergroup conflicts than those heretofore examined. Given these findings, we then sought to experimentally differentiate between metadehumanization and metaprejudice. In Study 2, we manipulated both metadehumanization and metaprejudice to (a) determine whether one or both cause greater outgroup hostility and (b) elucidate the underlying mechanisms by which they may produce this effect. Whereas metadehumanization produced greater hostility, metaprejudice did not. Moreover, although both metaperceptions inspired greater prejudice, only metadehumanization led to greater dehumanization. We conclude that metadehumanization may be a particularly potent fomenter of hostility because it inspires reciprocal dehumanization over and above more general negative bias.

On the current scale of the Internet, the single web crawler is unable to visit the entire web in an effective time-frame. So, we develop a distributed web crawler system to deal with it. In our distribution design, we mainly consider two facets of parallel. One is the multi-thread in the internal nodes; the other is distributed parallel among the nodes. We focus on the distribution and parallel between nodes. We address two issues of the distributed web crawler which include the crawl strategy and dynamic configuration. The results of experiment show that the hash function based on the web site achieves the goal of the distributed web crawler. At the same time, we pursue the load balance of the system, we also should reduce the communication and management spending as much as possible.

Israel’s 2013 Knesset elections, in which the incumbent ruling party was returned to power for the first time in a quarter-century, were noteworthy in several respects. The basic divisions of Israeli politics into geopolitical and socioeconomic blocs were unchanged, only small electoral shifts being registered. On the other hand, as this report shows, Prime Minister Benjamin Netanyahu barely achieved an electoral victory despite his overwhelming preponderance in public-opinion polls. Due to the rise of the new, personality-driven Yesh Atid party and the latter’s unlikely alliance with the settler-based Jewish Home, which together garnered as many Knesset seats as the winning Likud-Yisrael Beitenu list, for the first time in decades ultra-Orthodox parties were excluded from the governing coalition. The elections were marked by the near-invisibility of the Palestinian issue and Palestinian citizens of Israel. The report concludes that the continuing governing consensus in favor of “liberal colonialism” is unsustainable, although exploiting the “cracks” in that consensus is difficult and unlikely in the short term.

In this paper a novel and significant study into the usability of carousel interaction in the context of desktop interaction is presented. Two equivalent prototypes in an e-commerce context were developed. One version had a carousel and the other version did not have a carousel. These were then compared with each other in an empirical experiment with 40 participants. The data collected were statistically analysed and overall results showed that in terms of performance the Web site version without carousel outperformed the version with carousel. Furthermore, the subjective preferences of the participants were strongly in favour of the without carousel version of the site. The results of this study make an important contribution to knowledge suggesting that in many cases implementing a carousel is not the best design decision. The results of this paper are particularly significant in relation to desktop versioned Web sites and goal-driven tasks. Serendipitous-type tasks and mobile versioned web sites used on mobile devices with touch screens were not part of the scope of this work.

Purpose – This exploratory paper aims to extend the research on customer co-creation behavior into an emerging market. To this end, it empirically examines the influence of e-service quality dimensions on customers’ willingness to participate in online co-creation experience, in conjunction with customer attitude and intention. Design/methodology/approach – Data from a sample of 215 customers from the Egyptian telecommunication sector were collected and analyzed using structural equation modeling technique. Findings – The findings suggest that, although five e-service quality dimensions (efficiency, system availability, privacy, responsiveness and compensation) affect the attitude toward the Web site, another set of the dimensions (efficiency, fulfillment, compensation and contact) affects customers’ willingness to participate in the co-creation experience. The findings also support that customers’ attitudes toward the Web site affect the intention to use the Web site, which, in turn, affects customers’ willingness to participate in the online co-creation experience. Practical implications – In their move toward mass customization, companies face the challenge of engaging a huge number of users. Deep and engaging interactions with customers could be one of the differentiators a company might cultivate to serve the market better. Thus, online co-creation activities might broaden the horizon for a cost-effective approach striving for close ties and a high level of customer engagement. Originality/value – Despite the intensive use of the Internet in distributing e-services, little attention has been paid thus far to extend e-service quality models to incorporate customer participation in the online co-creation experience. In particular, this exploratory study identifies the important dimensions of e-service quality that influences customers’ willingness to participate in the online co-creation experience.

To find a strategy for improving the competitiveness of Web sites, it is necessary to use comprehensive, integrated Web site quality dimensions that effectively discover which improvements are needed. Previous studies on Web site quality, however, seem to have inconsistent and confusing scopes, creating a need of reconciliation among the quality dimensions. Therefore, this chapter attempts to provide a Web site quality model that can comprise all the quality scopes provided by previous studies. The relationship between the specific dimensions of the quality model and the characteristics or merits of Web 2.0 was discussed in this chapter with actual Web site examples. It is expected that this study can help Web sites improve their competitiveness in the Web 2.0 environment.

Litwin, Eric. Pete the Cat and His Four Groovy Buttons.  Illus. James Dean. New York: Harper, 2012. Print. Pete, the laid back, imperturbable puss is back and this time author and children’s performer Eric Litwin incorporates math into the story. Pete puts on his favourite shirt and begins to sing about his buttons. There is lots of repetition to help kids learn about numbers and subtraction. First Pete thinks about the total number of buttons and the numeral is displayed. Then the word “four” appears twice in the refrain: “My buttons my buttons, my four groovy buttons”. One by one the buttons pop-off and each time the resulting equation is displayed: “How many buttons are left? 4-1=3”.  This sequence repeats until he is down to his belly button! As with the other Pete books, there is also a very important underlying message: don’t sweat the small stuff.  Each time he loses another button, the author asks: “Did Pete cry? Goodness, no! Buttons come and buttons go”. This is reinforced in the conclusion: “I guess it simply goes to show that stuff will come and stuff will go.  But do we cry? Goodness, No! We keep on singing”. Artist James Dean first painted an image of Pete in 1999 and the little bluish-black cat with the big yellow eyes is still going strong.  His images are composed of bright, high-contrast colours. The visible brush strokes and thick black outlines create lots of interesting textures and highlights.  Of particular note are the buttons that leave long spirals of black trailing behind them and look as if they are popping right off the page. Again, as with previous Pete books, ( I Love my White Shoes and Rockin’ My School Shoes),  there is a free downloadable song available from the Harper Collins Web site (http://www.harpercollinschildrens.com/feature/petethecat/). The book is certainly engaging enough to be enjoyed on its own. However, there is also a substantial amount of bonus material on the web site that can be incorporated into school lessons or enjoyed at home: the song, links to a YouTube video that pairs animated images from the book with the song, printable activities and a link to a “School Jam” ipad/iphone app featuring Pete. A clever fusion of music and math sprinkled with a life lesson in resilience, this book would make a groovy addition to school and home libraries for preschool to early elementary school-aged children. Highly Recommended: 4 out 4 starsReviewer: Kim Frail Kim is a Public Services Librarian at the H.T. Coutts Education Library at the University of Alberta. Children’s literature is a big part of her world at work and at home. She also enjoys gardening, renovating and keeping up with her two-year old.

The 2018 Russian presidential election was effectively a contest not between Vladimir Putin and the other seven candidates on the ballot paper, but between Putin and the level of election turnout. Anything less than a large majority based on a respectable level of turnout would have undermined Putin’s legitimacy to serve for a further six-year term. In the event, Putin achieved his goal. Through the analysis of public opinion polls conducted by the Levada Center, we examine the background to the election. Putin’s success can be traced, first to long-standing patterns of differential turnout across the regions and, second, administrative initiatives by the election authorities which created a renewed confidence in the integrity of the election process.

Web usability is the ease of use of a website. Some goals of usability are the presentation of information and choices in a clear and concise way, a lack of ambiguity and the placement of important items in appropriate areas. On the other hand, user experience is something more than usability. It includes each and every experience that the users have while using the service. And of course, usability rules affect the user experience. In this study, understanding the principles of user-centered design and how it improves user experience is the main purpose. For this aim, https://www.virginamerica.com, which is the web site that gained the two thousand sixteen Best User Experince award from The Webby Awards, has been studied as a case study.    Keywords: web design, user experience, Virgin America.
