Abstract This article provides a comprehensive analysis of the Islamic State's use of images taken by drones, drawing on a dataset of ISIS propaganda images from October 2016 to December 2018. Analysing the three principal uses of drone imagery by ISIS—images of drone strikes, images of other attacks and observation—we argue that ISIS's use of drones distinguishes itself from other state and non-state uses of drones primarily by its communicative and symbolic value. While ISIS’ use of drone strikes takes place in a tactical rather than strategic setting, its employment of drones to film VBIED attacks allows them to achieve a strategic effect. After outlining ISIS’ use of drones for combat air support and to film ground (particularly VBIED) attacks, we argue, drawing on political geography, that ISIS employs drones in propaganda to stake and reinforce a claim to sovereign control of territory, performed through the flying of aircraft. The use of drone imagery, we argue, taps into long-standing visual and discursive strategies which associate vertical hierarchy and flying with mastery and control, allowing ISIS to display attributes of aerial sovereignty. This article, through an analysis of ISIS drone propaganda, provides a rare insight into non-state actors’ perception of drones and the communicative value of drone images, in addition to suggesting further avenues for the incorporation of political–geographical studies of verticality into the study of political violence and rhetoric.

Much of the literature, policies, programs, and investment has been made on mental health, case management, and suicide prevention of veterans. The Australian “veteran community is facing a suicide epidemic for the reasons that are extremely complex and beyond the scope of those currently dealing with them.” (Menz, D: 2019). Only limited work has considered the digital transformation of loosely and manual-based historical records and no enablement of Artificial Intelligence (A.I) and machine learning to suicide risk prediction and control for serving military members and veterans to date. This paper presents issues and challenges in suicide prevention and management of veterans, from the standing of policymakers to stakeholders, campaigners of veteran suicide prevention, science and big data, and an opportunity for the digital transformation of case management.

Galileo Unbound: A Path Across Life, The Universe and Everything traces the journey that brought us from Galileo’s law of free fall to today’s geneticists measuring evolutionary drift, entangled quantum particles moving among many worlds, and our lives as trajectories traversing a health space with thousands of dimensions. Remarkably, common themes persist that predict the evolution of species as readily as the orbits of planets or the collapse of stars into black holes. This book tells the history of spaces of expanding dimension and increasing abstraction and how they continue today to give new insight into the physics of complex systems. Galileo published the first modern law of motion, the Law of Fall, that was ideal and simple, laying the foundation upon which Newton built the first theory of dynamics. Early in the twentieth century, geometry became the cause of motion rather than the result when Einstein envisioned the fabric of space-time warped by mass and energy, forcing light rays to bend past the Sun. Possibly more radical was Feynman’s dilemma of quantum particles taking all paths at once—setting the stage for the modern fields of quantum field theory and quantum computing. Yet as concepts of motion have evolved, one thing has remained constant, the need to track ever more complex changes and to capture their essence, to find patterns in the chaos as we try to predict and control our world.

AbstractDerivatives of equations of motion (EOM) describing the dynamics of rigid body systems are becoming increasingly relevant for the robotics community and find many applications in design and control of robotic systems. Controlling robots, and multibody systems comprising elastic components in particular, not only requires smooth trajectories but also the time derivatives of the control forces/torques, hence of the EOM. This paper presents the time derivatives of the EOM in closed form up to second-order as an alternative formulation to the existing recursive algorithms for this purpose, which provides a direct insight into the structure of the derivatives. The Lie group formulation for rigid body systems is used giving rise to very compact and easily parameterized equations.

Recurrent Vitreous Hemorrhage

MicroRNAs (miRNAs) can provide insight into the pathophysiological states of ocular tissues such as proliferative diabetic retinopathy (PDR). In this study, differences in miRNA expression in vitreous from PDR patients with and without incidence of recurrent vitreous hemorrhage (RVH) after the initial pars-plana vitrectomy (PPV) were analyzed, with the aim of identifying biomarkers for RVH. Fifty-four consented vitreous samples were analyzed from patients undergoing PPV for PDR, of which eighteen samples underwent a second surgery due to RVH. Ten of the sixty-six expressed miRNAs (miRNAs-19a, -20a, -22, -27a, -29a, -93, -126, -128, -130a, and -150) displayed divergences between the PDR vitreous groups and to the control. A significant increase in the miRNA-19a and -27a expression was determined in PDR patients undergoing PPV as compared to the controls. miRNA-20a and -93 were significantly upregulated in primary PPV vitreous samples of patients afflicted with RVH. Moreover, this observed upregulation was not significant between the non-RVH and control group, thus emphasizing the association with RVH incidence. miRNA-19a and -27a were detected as putative vitreous biomarkers for PDR, and elevated levels of miRNA-20a and -93 in vitreous with RVH suggest their biomarker potential for major PDR complications such as recurrent hemorrhage incidence.

Abstract With the rise of right-wing populist ideologies and ensuing social polarization, political violence has become more widespread. Between 2017 and 2019, far-right extremists and anti-fascists engaged in more than twenty violent protest clashes in Portland, Oregon, USA. Through a protest event analysis of those clashes supplemented with a case study of the protest wave, this paper explores how the mechanisms of radicalization and de-radicalization operate when two violent protest movements collide and interact with state security forces. The three-way interaction among a movement, counter-movement, and the police can produce unanticipated outcomes. For example, rather than de-escalating the situation, police underbidding resulted in an increase in violence between the two movements. Understanding how the mechanisms of radicalization and de-radicalization function in a movement/counter-movement protest cycle can provide insight into the ways in which a movement’s strategy and their adversaries’ responses to it can increase or decrease levels of violence.

Background: Many countries use market forces to drive reform across disability supports and services. Over the last few decades, many countries have individualised budgets and devolved these to people with disability, so that they can purchase their own choice of supports from an available market of services.Key points for discussion: Such individualised, market-based schemes aim to extend choice and control to people with disability, but this is only achievable if the market operates effectively. Market stewardship has therefore become an important function of government in guiding markets and ensuring they operate effectively.The type of evidence that governments tend to draw on in market stewardship is typically limited to inputs and outputs and has less insight into the outcomes services do or do not achieve. While this is a typical approach to market stewardship, we argue it is problematic and that a greater focus on outcomes is necessary.Conclusions and implications: To include a focus on outcomes, we argue that market stewards need to take account of the lived experience of people with disability. We present a framework for doing this, drawing on precedents where people with disability have contributed lived experience evidence within other policy, research, knowledge production and advocacy contexts.With the lived experience evidence of people with disability included, market stewardship will be better able to take account of outcomes as they play out in the lives of those using the market and, ultimately, achieve greater choice and control for people with disability.<br />Key messages<br /><ul><li>Market stewardship is key to guiding quasi-markets, including in the disability sector;</li><br /><li>Evidence guiding market stewardship is often about inputs and outputs only;</li><br /><li>It would be beneficial to also include lived experience evidence from people with disability;</li><br /><li>We propose a framework for the inclusion of lived experience evidence in market stewardship.</li></ul>

Male professional athletes captivate fans and profoundly influence today’s society as part of the $1.3 trillion global sport industry. Although these athletes’ lives and careers are widely reported, scholarly knowledge about the women who support them—their wives—is extremely limited. Because these women’s voices have historically been stifled, their marriages are shockingly misunderstood. Based on findings from the first and only longitudinal study on the sport marriage, this book corrects the abundance of misinformation reported by all forms of media, dispels undeserved stereotypes, and addresses inaccurate assumptions about the heteronormative sport marriage. It demonstrates how, despite major changes in society and sport since the end of the last century, the fundamental nature of the heteronormative sport marriage has not changed. Sport wives remain isolated and subordinate, even while they make significant contributions to their husbands’ careers. Identifying the sport marriage as a career-dominated marriage, the book allows us into these women’s public and private lives, including their need to conform to unwritten rules and codes, adapt to abundant power and control issues, cope with groupies from all walks of life, and find ways to deal with their oft-justified fears about their husbands’ infidelity. The book shares intimate stories about, and provides rare and unflinching insight into, what it is like to be married to these highly visible men, what it means to be a woman in the male-dominated world of professional sports, and why women remain in a sport marriage at great cost to themselves.

Insight Into

This study sought to understand interpretations of interconnections between historical trauma, contemporary violence, and resilience in a Maya Achi community currently engaged in promoting peace and social change through popular education. In particular, the ways in which participants drew upon identity and memory in articulating characteristics of community distress and resilience are discussed. The research is informed by liberation psychology and critical perspectives of mental health, particularly considering the challenges inherent in the promotion of collective memory of trauma and resistance in contexts of violence and humanitarian settings. Participant reflections on historical and contemporary violence highlight elements of collective distress, connecting identity and memory with acts of both oppression and resistance. Education and development are signaled as possible sites of resilience but also experienced as sites of power upholding the status quo. Diverse experiences and applications of identity and memory provide insight into the ways in which community organizations working in contexts of political violence might navigate polarizing and paradoxical discourses in order to subvert, co-opt, or adapt to hegemonic cultural, political, and economic power relations in the process of transformation for collective resilience.

Introduction: Previous studies using cell culture models identified cyto-toxic effects of palmitate and that supplementation with oleate was protective by redirecting palmitate into triacylglycerol (TAG) stores. However, other cull culture studies reported that diacylglycerol transferase 1 (DGAT1), the last enzyme in TAG synthesis, demonstrated a preference for oleate. At present, it is not clear whether the supply of exogenous fatty acids (FA) to the heart is differentially allocated into the endogenous TAG pool. Therefore, the purpose of the present study is to examine the influence of palmitate and/or oleate on cardiac TAG incorporation. METHODS/RESULTS: Hearts were isolated from DGAT1-transgenic (DGAT) and control littermates (CON) and perfused in Langendorff mode with a mixed substrate buffer consisting of glucose, lactate, insulin, and FAs. The FA supply was varied with 0.2mM of both labeled (13C) and unlabeled (12C) FAs in 4 different experiments: 1) 13C/12C palmitate; 2) 13C/12C oleate; 3) 13C palmitate/12C oleate; 4) 13C oleate/12C palmitate. The incorporation of 13C palmitate or 13C oleate into the TAG pool was monitored by 13C NMR spectroscopy. In CON hearts (n=3), the incorporation of palmitate was ~65% higher than oleate when the perfusate contained a homogenous supply of FA. This was also observed in DGAT hearts (n=4) although the incorporation of both palmitate and oleate was ~75% higher compared to CON (P <0.05). In the presence of oleate, palmitate incorporation decreased 25-30% in both CON and DGAT hearts. In contrast, oleate incorporation was diminished by ~50% and ~100% in CON and DGAT hearts, respectively, in the presence of palmitate. CONCLUSIONS: These data suggest that when palmitate and oleate are provided in equal concentrations, palmitate is more readily utilized in the synthesis of endogenous TAG stores in the heart. Furthermore, although overexpression of DGAT increases both oleate and palmitate incorporation, the DGAT1 enzyme demonstrates a preference for palmitate. These findings provide insight into the relationship between exogenous FA supply and endogenous TAG dynamics in the contracting heart.
