High altitude stations and high energy cosmic rays

The advantages of high-altitude ground-based cosmic ray stations have been discussed in many past reports and conferences. It is very satisfying to observe this renewed attention to the research potentials of the Chacaltaya Laboratory. Specific research opportunities are reviewed, and possible future scenarios are noted

New empirical fits to the proton electromagnetic form factors

Recent measurements of the ratio of the elastic electromagnetic form factors of the proton, G_Ep/G_Mp, using the polarization transfer technique at Jefferson Lab show that this ratio decreases dramatically with increasing Q^2, in contradiction to previous measurements using the Rosenbluth separation technique. Using this new high quality data as a constraint, we have reanalyzed most of the world e-p elastic cross section data. In this paper, we present a new empirical fit to the reanalyzed data for the proton elastic magnetic form factor in the region 0 < Q^2 < 30 GeV^2. As well, we present an empirical fit to the proton electromagnetic form factor ratio, G_Ep/G_Mp, which is valid in the region 0.1 < Q^2 < 6 GeV^2

The celebrity entrepreneur on television: profile, politics and power

This article examines the rise of the ‘celebrity entrepreneur’ on television through the emergence of the ‘business entertainment format’ and considers the ways in which regular television exposure can be converted into political influence. Within television studies there has been a preoccupation in recent years with how lifestyle and reality formats work to transform ‘ordinary’ people into celebrities. As a result, the contribution of vocationally skilled business professionals to factual entertainment programming has gone almost unnoticed. This article draws on interviews with key media industry professionals and begins by looking at the construction of entrepreneurs as different types of television personalities and how discourses of work, skill and knowledge function in business shows. It then outlines how entrepreneurs can utilize their newly acquired televisual skills to cultivate a wider media profile and secure various forms of political access and influence. Integral to this is the centrality of public relations and media management agencies in shaping media discourses and developing the individual as a ‘brand identity’ that can be used to endorse a range of products or ideas. This has led to policy makers and politicians attempting to mobilize the media profile of celebrity entrepreneurs to reach out and connect with the public on business and enterprise-related issues

The Social Bridging Project: Intergenerational Phone-Based Connections With Older Adults During the COVID-19 Pandemic

Millions of Americans aged 65+ are socially isolated and millions more report feeling lonely. Social isolation and loneliness in older adults were compounded by stay-at-home orders and other COVID-19 prevention measures. Although many Americans experienced no difficulties transitioning to the use of electronic devices as their primary means of communication and connection, some older adults were not similarly able to espouse this shift. Our aim was to reduce the impact of social isolation on older adults, increase their comfort in expressing feelings of loneliness, and assist them in acquiring technology skills and accessing telehealth and community supports. Participants received wellness calls for conversation, resource access and technology-based support. Most participants reported decreased loneliness and increased connectedness after the calls; half reported increased ease in expressing their feelings. Programs that provide phone-based support for older adults may reduce loneliness and increase social connectedness

Threshold Electrodisintegration of ^3He

Cross sections were measured for the near-threshold electrodisintegration of ^3He at momentum transfer values of q=2.4, 4.4, and 4.7 fm^{-1}. From these and prior measurements the transverse and longitudinal response functions R_T and R_L were deduced. Comparisons are made against previously published and new non-relativistic A=3 calculations using the best available NN potentials. In general, for q<2 fm^{-1} these calculations accurately predict the threshold electrodisintegration of ^3He. Agreement at increasing q demands consideration of two-body terms, but discrepancies still appear at the highest momentum transfers probed, perhaps due to the neglect of relativistic dynamics, or to the underestimation of high-momentum wave-function components.Comment: 9 pages, 7 figures, 1 table, REVTEX4, submitted to Physical Review
