Over the past 15 years, YouTube has emerged as a large and dominant social media service, giving rise to a ‘platformed media system’ within its technical and regulatory infrastructures. This paper relies on a large-scale sample of channels (n=36M+) to explore this media system along three main lines. First, we investigate stratification and hierarchization in broadly quantitative terms, connecting to well-known tropes on structural hierarchies emerging in networked systems, where a small number of elite actors often dominate visibility. Second, we inquire into YouTube’s channel categories, their relationships, and their proportions as a means to better understand the topics on offer and their relative importance. Third, we analyze channels according to country affiliation to gain insights into the dynamics and fault lines that align with country and language. Throughout the paper, we emphasize the inductive character of this research, by highlighting the many follow-up questions that emerge from our findings.

And Control

Pipelines are an integral part of the world's economy and literally billions of pounds worth of fluids are moved each year in pipelines of varying lengths and diameters. As the cost of some of these fluids and the price of moving them has increased, so the need to measure the flows more accurately and control and operate the line more effectively has arisen. Instrumentation and control equipment has developed steadily in the past decade but not as fast as the computers and microprocessors that are now a part of most large scale pipeline systems. It is the interfacing of the new generation of digital and sometimes ‘intelligent’ instrumentation with smaller and more powerful computers that has led to a quiet but rapid revolution in pipeline monitoring and control. This paper looks at the more significant developments from the many that have appeared in the past few years and attempts to project future trends in the industry for the next decade.

The Impact

Social media systems are important for professional associations (PAs), providing new ways for them to interact with their members and stakeholders. Evaluation of the impact of social media is not straightforward. Here text analytics, specifically multidimensional scaling visualisation, is proposed as an approach for the characterisation of the large scale ‘conversations' occurring between an information and communication technology PA and its stakeholders via the Twitter social media system. In the case presented, there was found to be a significant level of congruence between the corresponding visualisations of tweets from the PA, and tweets to/about the PA, although differences were also observed. The new method proposed and piloted here offers a way for organisations to conceptualise, identify, capture and visualise the large-scale, ephemeral, text conversations about themselves on Twitter, and to assist them with key strategic uses of social media.

Get Out The Vote

People contribute more to public goods when their contributions are made more observable to others. We report an intervention that subtly increases the observability of public goods contributions when people are solicited privately and impersonally (e.g., mail, email, social media). This intervention is tested in a large-scale field experiment (n = 770,946) in which people are encouraged to vote through get-out-the-vote letters. We vary whether the letters include the message, “We may call you after the election to ask about your voting experience.” Increasing the perceived observability of whether people vote by including that message increased the impact of the get-out-the-vote letters by more than the entire effect of a typical get-out-the-vote letter. This technique for increasing perceived observability can be replicated whenever public goods solicitations are made in private.

Slave Population

Where did a large-scale Roman slave-owner obtain new slaves? Varro in effect tells us: Ephesus. And the answer would probably have been the same for many generations after his time. But can we work out more systematically and more thoroughly the relative importance of different kinds of sources? The sources which most require consideration are: (1) children born to slave-mothers within the Empire; (2) persons enslaved in provincial or frontier wars; (3) persons imported across the frontiers; (4) the ‘self-enslaved’; and (5) infants abandoned at places within the Empire.Several years ago, I argued on a number of grounds that the last of these sources, child-exposure, was more important than had previously been recognized. Subsequent reconsideration of the problem has led me to suspect that the source-material under-represents the amount of slave-importation across the frontiers, but not to doubt that child-exposure was very widespread or that it made an important contribution to the slave supply. Of the many subsequent discussions, the most original is that of Ramin and Veyne, who, in an article of 1981 too little attended to in the Anglo-Saxon world, made it appear very likely that those who voluntarily sold themselves into slavery were a larger category than scholars usually imagine. More recently, Scheidel has attempted to revive the case, previously propounded by Shtaerman among others, in favour of the self-reproductivity of the slave population.

AbstractThis conference on “Multi-wavelength AGN Surveys and Studies” has provided a detailed look at the explosive growth over the past decade, of available astronomical data from a growing list of large scale sky surveys, from radio-to-gamma rays. We are entering an era were multi-epoch (months to weeks) surveys of the entire sky, and near-instantaneous follow-up observations of variable sources, are elevating time-domain astronomy to where it is becoming a major contributor to our understanding of Active Galactic Nuclei (AGN). While we can marvel at the range of extragalactic phenomena dispayed by sources discovered in the original “Markarian Survey” – the first large-scale objective prism survey of the Northern Sky carried out at the Byurakan Astronomical Observtory almost a half-century ago – it is clear from the talks and posters presented at this meeting that the data to be be obtained over the next decade will be needed if we are to finally understand which phase of galaxy evolution each Markarian Galaxy represents.

Rapid Changes

This themed issue of Media International Australia brings together a collection of work that critically examines some of the rapid changes to the news media system in recent years, including an explosion of news sources, formats and increasingly popular hybrid styles and, the collapse in the authority of the trusted news sources of the past. Much news is now broken by social media, and journalists compete in a cycle of news and politics that has been dramatically influenced and sped up by 24-hour news channels. The role of journalists has changed, and they increasingly are being called up on to interpret and explain events rather than simply report them.

Prostate cancer (PCA) is a major health concern in current times. Ever since prostate specific antigen (PSA) was introduced in clinical practice almost three decades ago, the diagnosis and management of PCA have been revolutionized. With time, concerns arose as to the inherent shortcomings of this biomarker and alternatives were actively sought. Over the past decade new PCA biomarkers have been identified in tissue, blood, urine, and other body fluids that offer improved specificity and supplement our knowledge of disease progression. This review focuses on superiority of circulating biomarkers over tissue biomarkers due to the advantages of being more readily accessible, minimally invasive (blood) or noninvasive (urine), accessible for sampling on regular intervals, and easily utilized for follow-up after surgery or other treatment modalities. Some of the circulating biomarkers like PCA3, IL-6, and TMPRSS2-ERG are now detectable by commercially available kits while others like microRNAs (miR-21, -221, -141) and exosomes hold potential to become available as multiplexed assays. In this paper, we will review some of these potential candidate circulating biomarkers that either individually or in combination, once validated with large-scale trials, may eventually get utilized clinically for improved diagnosis, risk stratification, and treatment.

Developing sustainable and renewable energy sources is critical as higher and higher global energy and environmental challenges arise. Hydrogen has the highest mass/energy density of any fuel and is considered one of the best sources of clean energy. Water splitting is regarded as one of the most promising solutions for hydrogen production on a large scale. Highly efficient, durable, and cost-effective catalysts for hydrogen evolution reaction (HER) are critical in the realization of this goal. Among the many materials proposed, graphene-based materials offer some unique properties for HER catalysis. In this review, we present recent progress on development of graphene-based electrocatalysts toward HER throughout the past few years.

A New Technique

Background: Large scale craniectomy defects are commonly reconstructed with alloplastic implants, which can restore brain protection and promote cosmesis. However, esthetic outcomes can be subpar due to skin contour abnormalities and temporal hollowing. Herein we describe a senior craniofacial surgeon’s experience using a custom composite polyetheretherketone (PEEK) and porous polyethylene (Medpor) implant for alloplastic cranioplasty. Methods: A retrospective review was conducted of all PEEK-Medpor cranioplasty cases performed over the past 2 years. Patient characteristics, intraoperative information, surgical outcomes, and cosmetic outcomes were reviewed. Results: Sixteen patients (18-70 years of age) underwent surgery. Indications for cranioplasty included craniectomy due to trauma, stroke, or tumor, and bone resorption after a prior autologous cranioplasty. Augmentation of the temporalis area using alloderm or a muscle graft was performed in 7 cases. There were no intraoperative complications. Ultimately, all implants were maintained. One implant was temporarily removed due to infection, but successfully replaced. Three minor complications occurred. At an average follow-up of 9 months, 93.8% of surgical sites showed no significant temporal hollow. Conclusion: We describe a series of 16 implants using a composite PEEK Medpor implant for alloplastic cranioplasty, which resulted in a low infection rate and improved postoperative regional contour. Use of this implant with suspension of the temporalis muscle is a new technique that may allow for better adherence of the temporalis muscle to its anatomic position, while still providing good brain protection.
