ABSTRACT

The human papillomavirus (HPV) is one of the most common but preventable sexually transmitted infections that affect males and females but knowledge about it and vaccine uptake remain low. As organizations adopt eHealth communication strategies to communicate about HPV, this study examines the association between eHealth literacy (and related elements) and the motivators for HPV prevention that are based on the protection motivation theory. A survey was conducted among 472 young adults in Kenya and results show moderate eHealth literacy (M = 3.21, SD = 1.03) and online information seeking (M = 3.57, SD = 1.08) but low HPV knowledge and risk perception. eHealth literacy was correlated with HPV knowledge, perceived risk, self-efficacy, and response efficacy whereas online health information seeking were correlated with perceived seriousness of HPV infection. This study suggests examining the discrepancy between online information seeking and knowledge and the disparities in eHealth literacy among young adults in HPV communication.  相似文献

An important part of children's social and cognitive development is their understanding that people are psychological beings with internal, mental states including desire, intention, perception, and belief. A full understanding of people as psychological beings requires a representational theory of mind (ToM), which is an understanding that mental states can faithfully represent reality, or misrepresent reality. For the last 35 years, researchers have relied on false-belief tasks as the gold standard to test children's understanding that beliefs can misrepresent reality. In false-belief tasks, children are asked to reason about the behavior of agents who have false beliefs about situations. Although a large body of evidence indicates that most children pass false-belief tasks by the end of the preschool years, the evidence we present in this monograph suggests that most children do not understand false beliefs or, surprisingly, even true beliefs until middle childhood. We argue that young children pass false-belief tasks without understanding false beliefs by using perceptual access reasoning (PAR). With PAR, children understand that seeing leads to knowing in the moment, but not that knowing also arises from thinking or persists as memory and belief after the situation changes. By the same token, PAR leads children to fail true-belief tasks. PAR theory can account for performance on other traditional tests of representational ToM and related tasks, and can account for the factors that have been found to correlate with or affect both true- and false-belief performance. The theory provides a new laboratory measure which we label the belief understanding scale (BUS). This scale can distinguish between a child who is operating with PAR versus a child who is understanding beliefs. This scale provides a method needed to allow the study of the development of representational ToM. In this monograph, we report the outcome of the tests that we have conducted of predictions generated by PAR theory. The findings demonstrated signature PAR limitations in reasoning about the mind during the ages when children are hypothesized to be using PAR. In Chapter II, secondary analyses of the published true-belief literature revealed that children failed several types of true-belief tasks. Chapters III through IX describe new empirical data collected across multiple studies between 2003 and 2014 from 580 children aged 4–7 years, as well as from a small sample of 14 adults. Participants were recruited from the Phoenix, Arizona metropolitan area. All participants were native English-speakers. Children were recruited from university-sponsored and community preschools and daycare centers, and from hospital maternity wards. Adults were university students who participated to partially fulfill course requirements for research participation. Sociometric data were collected only in Chapter IX, and are fully reported there. In Chapter III, minor alterations in task procedures produced wide variations in children's performance in 3-option false-belief tasks. In Chapter IV, we report findings which show that the developmental lag between children's understanding ignorance and understanding false belief is longer than the lag reported in previous studies. In Chapter V, children did not distinguish between agents who have false beliefs versus agents who have no beliefs. In Chapter VI, findings showed that children found it no easier to reason about true beliefs than to reason about false beliefs. In Chapter VII, when children were asked to justify their correct answers in false-belief tasks, they did not reference agents’ false beliefs. Similarly, in Chapter VIII, when children were asked to explain agents’ actions in false-belief tasks, they did not reference agents’ false beliefs. In Chapter IX, children who were identified as using PAR differed from children who understood beliefs along three dimensions—in levels of social development, inhibitory control, and kindergarten adjustment. Although the findings need replication and additional studies of alternative interpretations, the collection of results reported in this monograph challenges the prevailing view that representational ToM is in place by the end of the preschool years. Furthermore, the pattern of findings is consistent with the proposal that PAR is the developmental precursor of representational ToM. The current findings also raise questions about claims that infants and toddlers demonstrate ToM-related abilities, and that representational ToM is innate.  相似文献

Information technology in the form of the Internet and its commercial offspring (referred to in this article collectively as the Net) has received much attention as a vehicle to increase political participation. In this article, we explore the potential of the Net, a vast, loosely coupled system of electronic forums, for facilitating and hindering democratic participation. In so doing, we identify five assumptions that undergird the claim that the Net will enhance democratic participation and suggest that increased democratic participation rests on three fundamental characteristics: access, voice, and dialogue. In order for this network of electronic forums to facilitate democratic participation, educational, economic, and cultural barriers to access, voice, and dialogue must be overcome. The final part of this article raises additional challenges to realizing democracy via the Net.  相似文献

Studies on serum arginase have shown that it is having the least unexplained variation and its activity is closely related with the severity of jaundice. Arginase is thus stable, consistent, efficient, specific and sensitive to changes. It is a better indicator of hepatocellular damage.  相似文献

Abstract

The study is a mixed-methods investigation of how urban schools are succeeding. The study surveyed 28 former students from urban schools in Oxnard, California. The qualitative responses represent themes that align to a high level of school connectedness and social–emotional learning (SEL) as key indicators of a successful urban school district. The responses also aligned with the thematic structures of the assets and relationships frameworks and to SEL standards.  相似文献

The positive impact of undergraduate research experiences on students’ post-secondary success is well-documented. However, these conclusions are drawn from undergraduate students who already participate; very little research has explored the pathways by which students enter these experiences. Using data from a multi-institutional survey, we examined students’ reasons for participating and differences across institutions and demographic groups. Overall, students cited social and experiential reasons as key motivators for participation and a perceived lack of research readiness as a key barrier. Differences were also found across academic year. Implications from this study address issues of access, preparation, and institutional policies around undergraduate research.  相似文献

Campus Club Cupcakes is an in‐class ‘introduction to operations management’ experiential learning exercise which can be used within minutes of starting the course. After reading the one‐page mini case, students are encouraged to meet each other and collaborate to determine if making and selling cupcakes to fellow business students would be a viable fundraising activity for a student club interested in completing a community development project in a developing country. The exercise is a variation and extension of the popular Kristen's Cookie Co. Harvard case which addresses capacity and bottlenecks. Campus Club additionally incorporates supply chain management and risk management concepts while also revealing how operations management integrates with the functional areas of marketing, accounting, and finance.  相似文献
