The dynamic models are proposed to investigate the influence node activity has on rumor spreading process in both homogeneous and heterogeneous networks. Different from previous studies, we believe that the activity of nodes in complex networks affects the process of rumor spreading. An active node can have contact with all the nodes it directly links to, while an inactive node could only interact with its active neighbors. We explore the joint effort of activity rate, spreading rate and network topology on (...) rumor spreading process by mean-field equations and numerical simulations, which reveals that there exists a critical curve consisting of critical activity rate and spreading rate; meanwhile, activity rate and spreading rate both have influence on the final rumor spreading scale.

How was this idealistic and utopian goal linked to specific political and economic programs? How do the policies of these particular regimes, based as they are on universal communist ideology, reflect national and cultural traditions? Cheng begins by exploring the origins of the idea of human perfectibility during the Enlightenment. His discussion moves to other European intellectual movements, and then to the creation of the Soviet Man, the first communist new man in world history. Subsequent chapters examine China's experiment with (...) human nature, starting with the nationalistic debate about a new national character at the turn of the twentieth century; and Cuban perceptions of the new man and his role in propelling the revolution from a nationalist, to a socialist, and finally a communist movement.

A growing body of business ethics research has shown that firms are beginning to embrace the lesbian, gay, bisexual, and transgender (LGBT) community with internal organizational policies and temporary activism activities. Despite these positive developments, little research has examined firms’ LGBT inclusion strategy at the product level and whether adding LGBT representation to products helps, hurts, or has no impact on corporate products’ market performance. Prior studies have examined LGBT-themed and LGBT-vague representations and identified limitations of both. The current research (...) presents an alternative LGBT-inclusive representation in which heterosexual and LGBT imagery are both presented, with the former receiving more exposure than the latter. A secondary analysis of 4216 movies and a controlled experiment reveal converging evidence: movies with LGBT-inclusive representation outperform those with no LGBT representation or with LGBT-themed representation. The superiority of LGBT-inclusive representation comes from its ability to appeal to consumer segments holding favorable and unfavorable LGBT attitudes. While cultural and entertainment products often play profound roles in changing society’s ethical standards and moral attitudes, they are rarely studied in the business ethics literature. Our findings fill this gap while answering a multimillion-dollar question for the entertainment industry. (shrink)

The 1932-33 Ukrainian Famine has always been a very controversial topic in Ukrainian history. Scholars generally blame Stalin and his rural collectivization policy. The lack of agricultural machinery, ineffective organization and the awkward relations between the village officials and local peasants all contributed to the famine. By using both Ukrainian and Western documents, this paper is devoted to the analyzing of the main causes of the famine.

PurposeTo study the changes in functional connections between the left and right hemispheres of patients with high myopia and healthy controls by resting functional magnetic resonance imaging based on voxel-mirrored homotopic connectivity. To study the changes in resting-state functional connectivity between the left and right hemispheres of patients with HM and healthy controls at rest by using resting functional magnetic resonance imaging based on voxel-mirror homotopy connectivity.Patients and MethodsA total of 89 patients with HM and 59 HCs were collected and (...) matched according to gender, age, and education level. The VMHC method was used to evaluate the changes in rsFC between cerebral hemispheres, and a correlation analysis was carried out to understand the differences in brain functional activities between the patients with HM and the HCs.ResultsCompared with the HCs, the VMHC values of the putamen and fusiform in the HM group were significantly lower.ConclusionThis study preliminarily confirmed the destruction of interhemispheric functional connection in some brain regions of the patients with HM and provided effective information for clarifying the neural mechanism of patients with HM.

The faces of both adults and children can be classified accurately by sex, even in the absence of sex‐stereotyped social cues such as hair and clothing (Wild et al., 2000). Although much is known from psychological and computational studies about the information that supports sex classification for adults' faces, children's faces have been much less studied. The purpose of the present study was to quantify and compare the information available in adults' versus children's faces for sex classification and to test (...) alternative theories of how human observers distinguish male and female faces for these different age groups. We implemented four computational/neural network models of this task that differed in terms of the age categories from which the sex classification features were derived. Two of the four strategies replicated the advantage for classifying adults' faces found in previous work. To determine which of these strategies was a better model of human performance, we compared the performance of the two models with that of human subjects at the level of individual faces. The results suggest that humans judge the sex of adults' and children's faces using feature sets derived from the appropriate face age category, rather than applying features derived from another age category or from a combination of age categories.

One heated argument in recent years concerns whether requiring real names supervision on social media will inhibit users' participation in discoursing online speech. The current study explores the impact of identification, perceived anonymity, perceived risk, and information credibility on participating in discussions on moral/ethical violations event on social network sites (SNS) in China. In this study, we constructed a model based on the literature and tested it on a sample of 218 frequent SNS users. The results demonstrate the influence of (...) identification and perception of anonymity: although the relationship between the two factors is negative, both are conducive to participation in discussion on moral/ethical violation topics, and information credibility also has a positive impact. The results confirmed the significance of risk perception on comments posted about moral/ethical violation. Our results have reference value for identity management and internet governance. Policies regarding users’ real names on the internet need to take into account the reliability of the identity authentication mechanism, as well as netizens’ perceptions of privacy about their identity and the necessity of guaranteeing content and information reliability online. We also offer some suggestions for future research, with a special emphasis on applicability to different cultures, contexts, and social networking sites. (shrink)

Growing opioid misuse in the United States has resulted in more children living with an adult with an opioid use history. Although an abundance of research has demonstrated a link between opioid misuse and negative parenting behaviors, few intervention efforts have been made to target this underserved population. The Family Check-Up has been tested in more than 25 years of research, across multiple settings, and is an evidence-based program for reducing risk behavior, enhancing parenting skills, and preventing the onset of (...) substance use. It is designed to motivate parents to engage in positive parenting practices and to change problematic parenting and has been tested across a variety of ages including early childhood and adolescence. It is highlighted in NIDA’s Principles of Substance Use Prevention for Early Childhood: A research-based guide as one of only three effective selective prevention programs for substance abuse among families with young children. Recently, we developed an online version of the FCU that has now been adapted for early childhood and families with opioid use histories. The online platform and telehealth model allow for wide-scale dissemination, ease of training with community providers, and increased public health reach for families in remote, rural areas. This is particularly important when targeting families with opioid misuse and addiction because there are high rates of addiction in remote areas, yet few services available. In this article, we describe the FCU Online and review new content in the model that targets a population of young adult parents with substance abuse histories, including opioid use. New modules include content focused on harm reduction for this high-risk population of parents, such as safety in the home, substance use while parenting, and managing conflict with partners and friends.

The flow of high-level talents in China is becoming more and more active and has a profound impact on the innovation and development of cities. Based on the research on the spatial distribution of the school and work stages of high-level talent in China, we study the structure and evolution of China’s high-level talent mobility network by using the data on the flow trajectory of talent among cities in China. The results show that: the spatial distribution of talents in the (...) two stages has greater consistency, but there is a change characteristic of “large dispersion, small agglomeration.” Compared with the school stage, the network in the work stage has much more connections; the centrality gap of cities has narrowed. “Core-periphery” structure of two networks is relatively significant and similar. The core layer in the two networks has not changed, but the subcore layer and the subedge layer have undergone changes. In addition, talents mainly flow to core and subcore cities. The space structure of network is more complex in the work stage, and it is expanding to the Guangdong-Hong Kong-Macao Greater Bay Area in southeastern China. (shrink)
