The new era of Gamification and Human-Focused Design optimizes for motivation and engagement over traditional Function-Focused Design. Within the industry, studies on game mechanics and behavioral psychology have become proliferate. However, few people understand how to merge the two fields into experience designs that reliably increases business metrics and generates a return on investment. Gamification Pioneer Yu-kai Chou takes readers on a journey to learn his sixteen years of obsessive research in creating the Octalysis Framework, and how to apply the framework to create engaging and successful experiences in their product, workplace, marketing, and personal lives

Emerging digital technologies give rise to digital entrepreneurship and the widespread phenomenon of open source collaboration (OSC) on GitHub for entrepreneurial pursuits. Although openness is a common theme in digital entrepreneurship, it is unclear how digital startups—that is, startups that that have digital artifacts at the core of their business model for value creation and capture—actually realize value from their OSC engagement. We develop a theoretical framework to explain how the engagement in OSC may affect the value of digital startups and how the effect is contingent on the stage of venture maturity (conception, commercialization, or growth) and the mode of OSC engagement (inbound or outbound). In analyses that pool 17,552 matched digital startups with monthly panel observations between 2008 and 2017, we find digital startups in the conception and commercialization stages benefit more from inbound OSC whereas the ones in the growth stage benefit more from outbound OSC. As digital startups increasingly use OSC for ideation, experimentation, and scaling, our contribution is to show whether, when, and how knowledge flows through OSC might affect the value of digital startups. We discuss implications for research on organizing for digital entrepreneurship as well as open innovation.

This paper examines where European professional teams recruit new players in order to shed light on the functioning of global value added chains in world football. Most studies either point to the increasing internationalization of football's labor force to argue that European clubs recruit from peripheral but culturally or historically related countries or turn to the experiences of players with domestic transfers to suggest that most teams recruit within their country. This study directly examines the recruitment activities of teams active in the highest two leagues of Europe's top seven countries between the 2003/2004 season and the 2011/2012 season. Results indicate that even though Europe's football labor force looks internationalized at first sight, many international players hold dual nationality and might be more aptly characterized as domestic players who are members of the large immigrant communities who came to Europe after the de-colonization of former colonies or as part of the stream of labor migrants in the 1960s and 1970s. Moreover, for most teams, domestic mobility forms the backbone of their recruitment activities, but some teams, especially in Portugal, buy football talent from teams in the global South and sell their best players to larger European teams. These results urge researchers to reconsider teams as more myopic and geographically bounded actors in global value added chains, incorporate domestic mobility into global value added chains, reconsider what counts as the core and the (semi-)periphery connected through the chains, and be wary of approaches taking countries or even leagues as the basic unit of analysis in global value added chains.

Coronavirus disease 2019 (COVID-19) has been causing negative impacts on various sectors in Sri Lanka, as a result of the public health interventions that the government had to implement in order to reduce the spread of the disease. Equivalent work carried out in this context is outdated and close to ideal models. This paper presents a mathematical epidemiological model, called SEQIJRDS, having additional compartments for quarantine and infected people divided into two compartments as diagnosed and non diagnosed, compared to the SEIR model. We have presented the rate equations for the model and the basic reproduction number is derived. This model considers the effect of vaccination, the viral load of the variants, mask use, mobility, contact tracing and quarantine, natural immunity development of the infected people, and immunity waning of the recovered group as key developments of the model. The model has been validated for the COVID-19 pandemic in Sri Lanka by parameter derivation using mathematical formulations with the help of the existing data, the literature, and by model fitting for historical data. We present a comparison of the model projections for hospitalized infected people, the cumulative death count, and the daily death count against the ground truth values and projections of the SEIR and SIR models during the model validation. The validation results show that the proposed SEQIJRDS model's 12-week projection performance is significantly better than both the SEIR and SIR models; the 2-, 6-, 8-, and 10-week projection performance is always better, and the 4-week projection performance is only slightly inferior to other models. Using the proposed SEQIJRDS model, we project mortality under different lockdown procedures, vaccination procedures, quarantine practices, and different mask-use cases. We further project hospital resource usage to understand the best intervention that does not exhaust hospital resources. At the end, based on an understanding of the effect of individual interventions, this ...

Human society has entered the Internet age, the network plays a very important function in all aspects of social management. In recent years, operational management of the taxi industry once again become the focus of the society because of various taxi network software prevalence. Take Shanghai Taxi management model for example, Compare the comparison of traditional and the present stage management mode and measures taken by the government. Summary and analysis the deficiency of the taxi industry and the government management. On this basis, developed the taxi industry how to take the role of the market in public services, how governments use the Internet to integrate the taxi market and improve management and service levels.

Dr. Hu Shih (1891-1962) was one of China's top scholars and diplomats and served as the Republic of China's ambassador to the United States during World War II. As early as 1941, Hu Shih warned of the fundamental ideological conflict between dictatorial totalitarianism and democratic systems, a view that later became the foundation of the Cold War narrative. In the 1950s, after Mao's authoritarian regime was established, Hu Shih started to analyze the development and nature of Communism, delivering a series of lectures and addresses to reveal what he called Stalin's "grand strategy" for facilitating the International Communist Movement. For decades--and today to a certain extent--Hu Shih's political writings were considered sensitive and even dangerous. As a strident critic of the Chinese Communist Party's oligarchical practices, he was targeted by the CCP in a concerted national campaign to smear his reputation, cast aspersions on his writings, and generally destroy any possible influence he might have in China. This volume brings together a collection of Hu Shih's most important, mostly unpublished, English-language speeches, interviews, and commentaries on international politics, China-U.S. relations, and the International Communist Movement. Taken together, these works provide an insider's perspective on Sino-American relations and the development of the International Communist Movement over the course of the 20th century
