Ecological theory predicts that individual survival should vary between sex and age categories due to differences in allocation of nutritional resources for growth and reproductive activities. During periods of environmental stress, such relationships may be exacerbated, and affect sex and age classes differently. We evaluated support for hypotheses about the relative roles of sex, age, and winter and summer climate on the probability of mountain goat (Oreamnos americanus) survival in coastal Alaska. Specifically, we used known‐fates analyses (Program MARK) to model the effects of age, sex, and climatic variation on survival using data collected from 279 radio‐marked mountain goats (118 M, 161 F) in 9 separate study areas during 1977–2008. Models including age, sex, winter snowfall, and average daily summer temperature (during Jul–Aug) best explained variation in survival probability of mountain goats. Specifically, our findings revealed that old animals (9+ yr) have lower survival than younger animals. In addition, males tended to have lower survival than females, though differences only existed among prime‐aged adult (5–8 yr) and old (9+ yr) age classes. Winter climate exerted the strongest effects on mountain goat survival; summer climate, however, was significant and principally influenced survival during the following winter via indirect effects. Furthermore, old animals were more sensitive to the effects of winter conditions than young or prime‐aged animals. These findings detail how climate interacts with sex and age characteristics to affect mountain goat survival. Critically, we provide baseline survival rate statistics across various age, sex, and climate scenarios. These data will assist conservation and management of mountain goats by enabling detailed, model‐based demographic forecasting of human and/or climate‐based population impacts. © 2011 The Wildlife Society.

There is a tradition of inquiry in Canada focused on the wider questions of technology and society. This set of themes may again be relevant as we are drawn away from the form of monopoly practices associated with mass media and we begin to deal with the resurgence of social and technological activity centred around contemporary transformations of the book, the newspaper, and the broadcast. More often than not, the instrument of this challenge is the computer. What are the outlines of this development and how can we address its consequences? Résumé: Il y a une tradition au Canada de recherches qui portent sur le domaine assez vaste de technologie et société. Cette tradition peut nous servir, comme nous nous éloignons de recherches sur les formes que prennent les pratiques monopolistiques reliées aux médias, et commençons à nous adresser à la renaissance d'activités sociales et technologiques centrées sur les transformations contemporaines du livre, du journal et de la télévision. Le catalyseur de cette renaissance, c'est en grande partie l'ordinateur. Quels sont les contours de ces transformations et comment adresser ses conséquences?

The rise of a global Internet poses a diversity of opportunities and challenges for Canadians. Predictably it also elicits rhetorical excess: that the Net will annihilate the barriers of geography and historical circumstance, or that the Net's borderless architecture manifestly plays into the hands of global actors; that the messaging capabilities of new media will make the Internet a seamless part of enhanced social life, or that it marks the rise of new forms of deception and social alienation; that the Web supports new forms of civic engagement allowing us to talk with anyone anywhere, or that it will privatize the public sphere, removing us further from our traditions of public participation. Such rhetorical dualisms, Steven Woolgar (1999) says, help to explain why as consumers and users we are so frequently confused and disappointed by sociotechnical change.Canadian communication researchers and educators should welcome the new communicational environment and the opportunity to play a role in its public understanding and further development. Recent data collected through a variety of national and international research projects is giving us a better sense of the trend lines in Internet development. We are beginning to get some purchase on the forces at work in shaping the Internet, the players and the backstage machinery, and how these compare and contrast across geographical and historical circumstances. A growing body of evidence on public concerns gives us some sense of what might undermine the Internet's broad base of support. Finally, there are provisional optics for looking at some of the content characteristics of the Internet, data that profile actual user activity indicate to some extent the scope and scale of content flows and audiences. Reflective practitioners are beginning to make us aware that research on human subjects has a complex ethical relationship to the virtual, especially as case-based studies and participant inquiries give us some feel for how the Net looks from the inside out.Two complementary types of data bookend current quantitative research, on which the present meta-analysis is based: media use surveys, specifically focused on the Internet, and Internet audience research, which generally produces ranking scales for the popularity of content categories and site sources. These research

Abundance estimation of hunted brown bear populations should occur on the same geographic scale as harvest data analyses for estimation of harvest rate. Estimated harvest rates are an important statistic for managing hunted bear populations. In Alaska, harvest data is collected over large geographic units, called Game Management Units (GMUs) and sub-GMUs. These sub GMUs often exceed 10,000 km2. In the spring of 2002, we conducted an aerial survey of GMU 9D (12,600 km2) and GMU 10 (4,070 km2) using distance sampling with mark-resight data. We used a mark-resight distance sampling method with a two-piece normal detection function to estimate brown bear abundance as 1,682.9 (SE = 174.29) and 316.9 (SE = 48.25) for GMU 9D and GMU 10, respectively. We used reported hunter harvest to estimate harvest rates of 4.35% (SE = 0.45%) and 3.06% (SE = 0.47%) for GMU 9D and GMU 10, respectively. Management objective for these units support sustained, high quality hunting opportunity which harvest data indicate are met with an annual harvest rate of approximately 5–6% or less.

Broken streets were-for Bialoszewski-inadequate containers of memory, yet they have been given major roles in the ways in which Warsaw has remembered its tragic Second World War history. Ruins have-as I will show presently-been promoted as putative monuments, as «holy» relics, and used as the backdrop for grand political gestures. Poignant, strangely expressive and yet literally mute, Warsaw's ruins have been made to «speak» for different interests. In this paper I set out to explore these acts of ventriloquism by architects, politicians, film
