The implications of teen sexting for healthy development continue to concern parents, academics, and the general public. Using a probability sample of high school students (N = 1,208) aged 12–18, the prevalence of sexting, associations with sexting, and associations between sexing and sexual activity were assessed. Seventeen percent both sent and received sexts, and 24% only received sexts. Sending and receiving sexts were positively associated with each other and both behaviors were associated with having peers who sext. Lifetime reports of sexual intercourse, anal sex, oral sex, and recent unprotected sex were positively associated with reports of texting 300 or more times per day, only receiving sexts, and both sending and receiving sexts.  相似文献   

Pedagogy and practice in STEM field experiences: intersections of student and mentor identity and impacts upon student outcomes     

Christopher J. Felege  Cheryl Hunter  Joshua Hunter  Susan N. Ellis-Felege 《师资教育杂志》2018,44(4):514-516

Practicums, internships and field experiences are essential components in many fields. These varied experiences embed both students and their mentors in immersive experiences. Such immersive experiences are essential for STEM students preparing for future jobs, yet little is known about how these research-intensive and immersive experiences impact the practice of teaching in the natural sciences. In order to evaluate the impact, opportunities and challenges associated with such experiences, our team collected and analysed end-of-semester reflections from five students and their faculty mentor. Thematic analysis related to inferences and implications about the impacts of the experience showed a need to formalize and further develop an understanding of both students’ self-identity and the cultural attitudes of the students and the mentor.  相似文献   

The Psychological Contracts of Undergraduate University Students: Who Do They See as Exchange Partners,and What Do They Think the Deals Are?     

Joshua R. Knapp  Suzanne S. Masterson 《Research in higher education》2018,59(5):650-679

The relationship between students and their academic institution is based on exchange. However, we have limited knowledge regarding how many exchanges students perceive, who (or what) the perceived exchange partners are, and what the perceived terms of those exchanges contain. To address this gap, we utilized a mixed-method approach to explore and describe the psychological contracts of two sets of undergraduate university students: newly entering freshman, and experienced university students. Results clearly demonstrated that students perceive numerous psychological contracts relevant to their education with a variety of partners both inside and at the boundaries of the institution. Results also demonstrated that these contracts are qualitatively and quantitatively distinct. The overarching implication of these findings is that students navigate a web of diverse exchange partners, and it would be a mistake for educators and researchers to focus exclusively on one or few relationships presupposed to be most important.  相似文献   

Enhancing children's literacy skills: designing the Q‐Tales ecosystem for children's e‐book design and publication          下载免费PDF全文

Bonnie Thompson Long  Tony Hall  Michael Hogan  Nikos Papastamatiou 《Literacy》2018,52(3):171-179

This article describes the conceptualisation and development of a pedagogical framework to support the design of e‐books for children to enhance literacy development. It emerged from research undertaken within the Q‐Tales international consortium project of the EU's Horizon 2020 Programme for Research and Innovation, where the aim was to facilitate key stakeholders to collaborate and participate in the online production and publication of high‐quality, educational e‐books for children. The pedagogical framework described here sought to answer the question “What concepts and principles undergird the effective design of pedagogically impactful e‐books for children?” It is grounded by the theoretical underpinnings of socio‐constructivism, constructionism and skill theory, and how they relate to children's literacy development. A framework describing different narrative forms and component features, key pedagogical activities appropriate for different stages of reading development and design recommendations regarding the integration of multimedia into e‐books are also central to the pedagogical framework. As well as informing the design of the Q‐Tales infrastructure for children's e‐book design and publication, we hope the guidelines and pedagogical activities enumerated here will be widely useful for those designing and developing digital, interactive narratives, particularly e‐books to enhance children's emerging literacy.  相似文献   

Are athletes on the right track? The effect of availability of an all-weather athletics track on athletics performance     

Richard Watt  Seamus Hogan 《Sport in Society》2018,21(3):546-557

In February of 2011, an earthquake destroyed the only all-weather athletics facility in the city of Christchurch, New Zealand. The all-weather track has yet to be replaced, and so since the loss of the track, local Christchurch athletes have only had a grass track for training and preparation for championship events. The present study considers what effect the loss of the training facility has had on the performance of athletes from Christchurch at national championship events. Not surprisingly, the study finds that there has been a deterioration in the performance in events that are heavily dependent upon the all-weather surface. However, somewhat more surprisingly, the loss of the track appears to have caused a significant improvement in the performance of Christchurch athletes in events that, while on the standard athletics programme, are not heavily dependent on track surface.  相似文献   

Changing attitudes and intentions related to doping: An analysis of individual differences in need for cognition     

Javier Horcajo  David Santos  Joshua J. Guyer  Lorena Moreno 《Journal of sports sciences》2013,31(24):2835-2843

ABSTRACT

Research has shown that athletes’ attitudes towards the use of banned performance-enhancing substances are reliable predictors of their intentions to use these substances, which in turn can be relevant predictors of their actual doping behaviours. Despite the important role played by attitudes and intentions in doping, research analysing how to change those attitudes and intentions is relatively scarce. The present study examined how individual differences in Need for Cognition (NC, Cacioppo & Petty, 1982) influenced doping-related attitude change and subsequent behavioural intentions. Participants were randomly assigned to read a persuasive message either against or in favour of legalising the use of several banned substances, including anabolic androgenic steroids (AAS) and Erythropoietin (EPO). In addition, participants completed the NC scale, and finally reported their attitudes and behavioural intentions regarding the legalisation proposal. As hypothesised, results showed that participants who received an anti-legalisation message had significantly more unfavourable attitudes towards the proposal than participants who received a pro-legalisation message, regardless of NC. However, as predicted, NC moderated the relationship between individuals’ attitudes and their intentions. That is, high-NC participants showed greater attitude-intention correspondence than low-NC participants.  相似文献   

Effect of Mastering Swim Skills on Older Adults' Self-Efficacy     

Patricia I. Hogan  James P. Santomier 《Research quarterly for exercise and sport》2013,84(3):294-296

Abstract

Two groups of 23 junior high school boys were tested before and after an eight weeks' progressive resistance training program. The experimental group participated in this program, but the control group took part only in regularly scheduled physical education classes. At the end of the eight weeks, it was found that the experimental group increased their ability to do pull-ups, push-ups, the Harvard Step Test, Dodge run, the Burpee test, and trunk extension and flexion. The control group improved in the Dodge run, the Burpee test, push-ups, and trunk extension. In no case did the improvement of the control group exceed the improvement of the experimental group. The experimental group also increased in anthropometric measurements. Medical examinations indicated that no harmful effects were experienced by either group.  相似文献   

Applying White Dialectics: Exploring Whiteness and Racial Identity among White College Athletes     

Joshua D. Vadeboncoeur  Trevor Bopp 《Quest (Human Kinetics)》2019,71(1):1-20

This article seeks to synthesize and apply White racial identity theory and concomitant research to the interaction between athletic and racial identity, specifically as it relates to the experiential variations of how race impacts White athletes within the college sport environment. White dialectics, or the tensions that White Americans experience as dominant social group members, serve as the guiding theoretical framework and provide a theoretical lens through which the experience of White college athletes is examined at each distinct dialectic. Through this article, the application of White dialectics offers a theoretical foundation for developing a better understanding of how White college athletes not only make sense of their racial identity, but also understand their racialized experiences within intercollegiate athletics.  相似文献   

Narrative Capacity,Resistance Performance,and the “Shape” of New Social Movement Networks     

Joshua D. Atkinson  Laura Cooley 《Communication Studies》2013,64(3):321-338

The current research explored two new social movement networks in the United States in order to demonstrate the impact of narrative capacity on the “shape” of an activist network. In particular, we found that activists in a network that demonstrated efficient narrative capacity described the hub organization in positive terms, while activists in a network that demonstrated poor narrative capacity held mixed perceptions about the hub. Some activists in the second network held positive perceptions about the organization, while others held negative perceptions. The observations from these two research sites led us to conceptualize activists' differing perceptions about their respective hub organizations as “distance” that they experienced from that hub. Therefore, two different star shapes emerged from our research: a symmetrical star and elongated star. Such findings demonstrate the importance for narrative capacity in the construction and maintenance of effective activist networks.  相似文献   

Irony and Language Expectancy Theory: Evaluations of Expectancy Violation Outcomes     

Joshua M. Averbeck 《Communication Studies》2013,64(3):356-372

Language expectancy theory (LET) provides the basis for a study of the relationship of ironic and literal messages in terms of persuasiveness and expectedness. The experimental design was a 2 (literal vs. ironic) × 2 (compliment vs. criticism) factor design. The expectation was that literal messages would be more expected and criticisms less preferred to compliments. The results indicated that the ironic messages tended to be negative, unexpected, and attributed to the situation as opposed to the sender. Compliments were associated with fewer behavioral intentions than were criticisms. The interaction also revealed that the ironic messages were a safe middle ground between literal criticisms and compliments in terms of fostering behavioral changes.  相似文献
