Teaching Social Justice: Intergenerational Service Learning in a Digital Media Course

Digital media play an increasingly dominant role in reinforcing and challenging power inequality in social and institutional relationships. This paper describes how a service-learning component engaged students in community-based interactions that not only deepened their understanding of course content but also increased their commitment to diversity, community issues, and personal development. A close look at three case studies shows that integrating service learning into a first year seminar on digital media and social justice had positive outcomes for students when intentionally paired with community partners offering course-related projects

Electronic Nicotine Product (ENP) Graphic Warnings: Association between Exposure and Changes in Perceived Susceptibility and Severity of Explosion and Lung Injuries

Electronic nicotine products (ENPs) are the most prevalent form of tobacco use among U.S. young adults. Research is needed to investigate how to communicate new risks from ENPs to the public. In this study, we tested the comparative persuasiveness of ENP explosion and lung injury graphic warnings. We recruited a sample of 343 young adults (18 to 28 years; 146 male, 197 female), including both ENP users and nonusers, via Amazon Mechanical Turk in October 2020. We randomly assigned participants to one of six exposure conditions: two images of lung injuries with prevalence statistics, two images of battery explosion injuries with prevalence statistics, and two images of ENPs with messages about chemicals or nicotine/addiction. We measured perceptions and intention to use ENPs before and after exposure. Linear regression models examined whether exposure conditions were associated with post-exposure perceived susceptibility and severity of ENP lung injuries and explosion injuries, perceived intensity, fear, and intention to use, adjusting for baseline values and potential confounders. Compared to the chemicals/nicotine messages, explosion and lung injury stimuli were perceived to be more intense (p \u3c .001) and evoked greater fear (p \u3c .001). Both explosion injury images were associated with increased perceived susceptibility (p \u3c .01) and severity (p \u3c .001). One lung injury image was associated with increased perceived susceptibility (p \u3c .01) and reduced intention to use ENPs (p \u3c .05). Our results show that ENP graphic warnings can increase threat perceptions about ENP lung and explosion injuries among young adults. Similar graphic warnings may be effective for other harms associated with ENPs

'Surely the most natural scenario in the world’: Representations of ‘Family’ in BBC Pre-school Television

Historically, the majority of work on British children’s television has adopted either an institutional or an audience focus, with the texts themselves often overlooked. This neglect has meant that questions of representation in British children’s television – including issues such as family, gender, class or ethnicity - have been infrequently analysed in the UK context. In this article, we adopt a primarily qualitative methodology and analyse the various textual manifestations of ‘family’, group, or community as represented in a selected number of BBC pre-school programmes. In doing so, we question the (limited amount of) international work that has examined representations of the family in children’s television, and argue that nuclear family structures do not predominate in this sphere

Binge-watching: Video-on-demand, quality TV and mainstreaming fandom

This article explores the concept of the binge as viewing protocol associated with fan practices, industry practice and linked to ‘cult’ and ‘quality’ serialised content. Viewing binge-watching as an intersection of discourses of industry, audience and text, the concept is analysed here as shaped by a range of issues that dominate the contemporary media landscape. In this, factors like technological developments, fan discourses and practices being adopted as ‘mainstream’ media practice, changes in the discursive construction of ‘television’ and an emerging Video-on-Demand industry contribute to the construction of binge-watching as deliberate, self-scheduled alternative to ‘watching TV’

Dacarbazine and interferon α with or without interleukin 2 in metastatic melanoma: a randomized phase III multicentre trial of the Dermatologic Cooperative Oncology Group (DeCOG)

In several phase II-trials encouraging tumour responses rates in advanced metastatic melanoma (stage IV; AJCC-classification) have been reported for the application of biochemotherapy containing interleukin 2. This study was designed to compare the efficacy of therapy with dacarbazine (DTIC) and interferon α (IFN-α) only to that of therapy with DTIC and IFN-α with the addition of interleukin 2 (IL-2) in terms of the overall survival time and rate of objective remissions and to provide an elaborated toxicity profile for both types of therapy. 290 patients were randomized to receive either DTIC (850 mg/m2every 28 days) plus IFN-α2a/b (3 MIU/m2, twice on day 1, once daily from days 2 to 5; 5 MIU/m23 times a week from week 2 to 4) with or without IL-2 (4.5 MIU/m2for 3 hours i.v. on day 3; 9.0 MIU/m2i.v. day 3/4; 4.5 MIU/m2s.c. days 4 to 7). The treatment plan required at least 2 treatment cycles (8 weeks of therapy) for every patient. Of 290 randomized patients 281 were eligible for an intention-to-treat analysis. There was no difference in terms of survival time from treatment onset between the two arms (median 11.0 months each). In 273 patients treated according to protocol tumour response was assessable. The response rates did not differ between both arms (P = 0.87) with 18.0% objective responses (9.7% PR; 8.3% CR) for DTIC plus IFN-α as compared to 16.1% (8.8% PR; 7.3% CR) for DTIC, IFN-α and IL-2. Treatment cessation due to adverse reactions was significantly more common in patients receiving IL-2 (13.9%) than in patients receiving DTIC/IFN-α only (5.6%). In conclusion, there was neither a difference in survival time nor in tumour response rates when IL-2, applied according to the combined intravenous and subcutaneous schedule used for this study, was added to DTIC and IFN-α. However, toxicity was increased in melanoma patients treated with IL-2. Further phase III trials with continuous infusion and higher dosages must be performed before any final conclusions can be drawn on the potential usefulness of IL-2 in biochemotherapy of advanced melanoma. © 2001 Cancer Research Campaign http://www.bjcancer.co

Immunological changes in nestlings growing under predation risk

Predation is one of the most relevant selective forces in nature. However, the physiological mechanisms behind anti-predator strategies have been overlooked, despite their importance to understand predator-prey interactions. In this context, the immune system could be especially revealing due to its relationship with other critical functions and its ability to enhance prey's probabilities of survival to a predator's attack. Developing organisms (e.g. nestlings) are excellent models to study this topic because they suffer a high predation pressure while undergoing the majority of their development, which maximizes potential trade-offs between immunity and other biological functions. Using common blackbirds Turdus merula as model species, we experimentally investigated whether an elevated nest predation risk during the nestling period affects nestlings' immunity and its possible interactions with developmental conditions (i.e. body condition and growth). Experimental nestlings modified some components of their immunity, but only when considering body condition and growth rate, indicating a multifaceted immunological response to predation risk and an important mediator role of nestlings' developmental conditions. Predation risk induced a suppression of IgY but an increase in lymphocytes in nestlings with poor body condition. In addition, experimental but not control nestlings showed a negative correlation between growth and heterophils, demonstrating that nest predation risk can affect the interaction between growth and immunity. This study highlights the importance of immunity in anti-predator response in nestlings and shows the relevance of including physiological components to the study of predation risk.</p
