Movies, and perhaps more importantly documentary movies, need to be separated into good documentaries and important documentaries. Citizenfour would then fall squarely in this second category, and require viewing for its import rather than its simulation. Citizenfour documents the days preceding and during the release of information gained by Edward Snowden, which exposed the depth of surveillance activities conducted by the NSA and other security agencies. Directed by Laura Poitras and reporting by Glenn Greenwald, the film documents the process of information release, the technological capability of the spying agencies, and the person (Snowden) behind the release of this information. .This film and its subject matter are important. They highlight the reality of information accessibility, the surveillance that is currently occurring, the scope and depth of this activity, and government's complicity in this activity. Jeremy Bentham described a perfect prison where those who thought they were being watched modified their behaviour accordingly. Snowden, facilitated by Poitras and Greenwald, demonstrates in Citizenfour that this prison has already been built, and is present every time we log on to a computer system. For those involved in social change, a risk is that the threat of observation may change behaviour. This needs to be resisted.

Constant Struggle examines how Canadian democracy has been understood by its advocates and resistors, exploring key historical realities that have shaped it. Scholars from a range of disciplines tackle the methodological issues of this elusive concept, offering a renewed, sometimes unsettling depiction of Canada's democratization process.

The impact of social media on the media environment has been widely recognized; as has the ability of extremist and adversarial organizations to exploit social media to publicize their cause, spread their propaganda, and recruit vulnerable individuals. Supporting the growth of social media has been the phenomenal global increase in mobile telephone usage, and much of this increase is in areas where there are existing conflicts or conflicts are highly likely. These combined revolutions will increasingly have a direct impact on virtually all aspects of military operations in the 21st century. In doing so, social media will force significant changes to policy, doctrine, and force structures. This Letort Paper explores the implications of social media for the U.S. Army. ; https://press.armywarcollege.edu/monographs/1292/thumbnail.jpg

Lung injury is frequently a component of the polytrauma sustained by military personnel surviving blast on the battlefield. This article describes a case series of the military casualties admitted to University Hospital Birmingham's critical care services (role 4 facility), during the period 1 July 2008 to 15 January 2010. Of the 135 casualties admitted, 107 (79.2%) were injured by explosive devices. Plain chest films taken soon after arrival in the role 4 facility were reviewed in 96 of the 107 patients. In 55 (57.3%) films a tracheal tube was present. One or more radiological abnormalities was present in 66 (68.75%) of the films. Five patients met the consensus criteria for the definition of adult respiratory distress syndrome (ARDS). The majority of casualties with blast-related lung injury were successfully managed with conventional ventilatory support employing a lung protective strategy; only a small minority received non-conventional support at any time in the form of high-frequency oscillatory ventilation. Of those casualties who survived to be received by the role 4 facility, none subsequently died as a consequence of lung injury.

We review a family of modified autoregressive models in both discrete‐ and continuous‐time formulations. We present the case for these models by showing first how a standard discrete‐time autoregressive model with orders selected by criteria such as the Akaike information criterion can fail to identify the correct periods of cyclical variations in a simulated example. We then show how the modified models can overcome this failure, and further illustrate this success with a real example of an unemployment series. A new extension of the continuous‐time modified model to multivariate series is described. This is applied to a pair of series with mixed monthly, quarterly and annual sampling intervals. Common cyclical components of the two series are then extracted.

Looking after pets provides several benefits in terms of children's social interactions, factual and conceptual knowledge about these animals. In this study we investigated effects of rearing experiences on children's factual knowledge and alternative conceptions about animals. Data obtained from 1541 children and 7705 drawings showed very strong bias towards rearing vertebrates and a general ignorance of invertebrates. Experiences with rearing animals significantly contributed to children's knowledge about animal' internal organs. Children who reported keeping two or more animals acquired better scores in our study than children keeping only one or no animals. Moreover, the misclassification of invertebrates was not influenced by children's experiences of keeping animals. Although girls showed better knowledge about the anatomy of animals and actually kept more animals than did boys, they also more frequently misclassified invertebrates by drawing bones inside the bodies of the animals, hence allocating them to the vertebrates. We propose that science activities with animals should be more focused on rearing invertebrates and improving children's attitudes and knowledge about them.
