This paper presents an axiomatic framework for measuring lifetime poverty over multiple periods. For an individual, we argue that lifetime poverty is influenced by both the “snapshot” poverty of each period and the poverty level of the “permanent” lifetime consumption; it is also influenced by how poverty spells are distributed over the lifetime. We axiomatically characterize classes of lifetime poverty indices and derive dominance conditions of poverty orderings for both individual and societal lifetime poverty measurements.  相似文献

This study examined parents’ understanding of and experience with child-targeted advergames through exploratory interviews and quantitative pretests of an advergaming definition. Exploratory findings revealed that parents tended to overgeneralize when identifying advergames. Through the use of an online survey, this study also examined how parental socialization styles affect parents’ attitudes toward advergames. As predicted, results indicate that authoritarian and authoritative parents hold more negative perceptions toward advergames compared to indulgent parents, while all parenting styles exhibited negative leanings toward advergaming as a practice. These findings indicate the efficacy of parental socialization theory in explaining parents’ perceptions and attitudes toward this new form of advertising—advergames. We discuss important implications for regulators, practitioners, and parents.  相似文献

A supply response model for New Zealand apples is specified and equations for new plantings, removals, yields and adoption of an innovation are estimated. The model expands on perennial crop models previously estimated by incorporating the time pattern of adoption of a planting innovation and formulation of a measure of yield expectations given technological change.  相似文献

Few scholarly research studies and governmental reports have focused on parents' opinions regarding food and beverage marketing toward children and their thoughts as to what can be done to empower them in the childhood obesity debate. The current study represents a missing link in traditional childhood obesity research by identifying the possible contribution of food retailers in helping struggling parents with the issue at hand. Results of an online survey conducted among 282 parents of 6–11-year-olds reveal that parents are looking for partnerships between food marketers and retailers in future promotional endeavors.  相似文献

The proliferation of covert online advertising formats such as advergames has raised concerns about consumers’ ability to recognize such content as advertising and about how recognition affects evaluative outcomes. The present research utilized an online experiment (N?=?179) to examine differences between covertness of advertising format (advergame vs. online video commercials) on advertising recognition, and whether sponsorship transparency mediates – and mitigates – the negative effects of advertising recognition on attitude toward the ad, attitude toward the brand, and purchase intent. The results show that covertness of advertising format, recognition, and sponsorship transparency all shape consumers’ responses to online ads. Specifically, the predicted negative indirect effect of covertness of advertising format on attitudes and behavioral intention via advertising recognition reversed valance when sponsorship transparency was included in the serial mediation model.  相似文献

Cultivating students’ design abilities can be highly beneficial for the learning of science, technology, engineering, and mathematics (STEM) concepts, and development of higher-order thinking capabilities (National Academy of Engineering and National Research Council in STEM integration in k-12 education: status, prospects, and an agenda for research, The National Academies Press, Washington, 2014). Therefore, examining students’ strategies, how they distribute their cognitive effort, and confront STEM concepts during design experiences, can help educators identify effective and developmentally appropriate methods for teaching and scaffolding design activities for students (National Research Council in standards for k-12 engineering education? The National Academies Press, Washington, 2010). Yet, educational researchers have only recently begun examining students’ engineering design cognition at the P-12 level, despite reports such as Standards for K-12 Engineering Education? (National Research Council 2010) designating this area of research as lackluster. Of the recent studies that have investigated engineering design cognition at the P-12 level, the primary method of investigation has been verbal protocol analysis using a think-aloud method (Grubbs in further characterization of high school pre- and non-engineering students’ cognitive activity during engineering design, 2016). This methodology captures participants’ verbalization of their thought process as they solve a design challenge. Analysis is typically conducted by applying a pre-determined coding scheme, or one that emerges, to determine the distribution of a group’s or an individual’s cognition. Consequently, researchers have employed a variety of coding schemes to examine and describe students’ design cognition. Given the steady increase of explorations into connections between P-12 engineering design cognition and development of student cognitive competencies, it becomes increasingly important to understand and choose the most appropriate coding schemes available, as each has its own intent and characteristics. Therefore, this article presents an examination of recent P-12 design cognition coding schemes with the purpose of providing a background for selecting and applying a scheme for a specific outcome, which can better enable the synthesis and comparison of findings across studies. Ultimately, the aim is to aid others in choosing an appropriate coding scheme, with cognizance of research analysis intent and characteristics of research design, while improving the intentional scaffolding and support of design challenges.  相似文献

Studies of the local population's perception of tourism impact are useful in setting up programs to minimize friction between tourists and residents, and in formulating plans to gain resident support of tourist ventures. This study identifies the positive and negative aspects of tourism as perceived by the Santa Marta residents, and the influence of selected variables on resident response. It is hypothesized that the perception of tourist impact varies with the distance a person lives from the tourist zone and with the resident's socio-economic status. It is found that despite the perception of some serious negative aspects, Santa Marta residents consider the overall impact of tourism to be beneficial. They want their government to offer more economic incentives and eliminate any restrictive measures in order to stimulate tourism in the area. The positive attitudes of the Santa Marta residents toward tourism may be a function of the incipient stage of tourism development in this area.  相似文献
