Global Threats, 2014

In this poll on global and national threats to security and safety, just over half (55%) of Canadians say they aren't confident in the ability of domestic security services to prevent homegrown radicals from carrying out terrorist attacks in Canada.

Baggage Fees, 2014

Canada's major airlines are on the hot seat as a result of recently announced $25 fees for the first checked bag for flights in Canada. This poll shows that Canadian adults are widely opposed to the baggage fees recently imposed by domestic airlines.

Invited lectures from a spatial orientation symposium in honor of Frederick Guedry, Day 2

This report contains the invited lectures from day 2 of a Spatial Orientation Symposium in honor of the late Dr. Frederick Guedry, held at the Institute of Human and Machine Cognition (IHMC) in Pensacola, Florida in November of 2010. The conference was sponsored by the Coalition Warfare Program of the Office of the Under Secretary of Defense for Acquisition, Technology, and Logistics. It was organized by Drs. Angus Rupert and Ben Lawson (USAARL) and hosted by Drs. Anil Raj and Ken Ford (IHMC). The lectures from day 1 are in Lawson et al., 2014. Day 2 includes lectures by Drs. Scott, Ben Lawson, Angus Rupert, Owen Black, Karen Atkins, Kim Gottshall, Anil Raj, and Måns Magnusson. The lectures focus on the structure, function and reflexes of the vestibular system, orientation perceptions, motion sickness, adaptation, and rehabilitation. This report also features banquet talks given by Drs. Lawson and Rupert, in which they honor Dr. Fred Guedry. Also featured is an interview with Dr. Guedry, conducted by a Navy historian, in which the reader can catch a glimpse into Dr. Guedry's wartime experiences and early days as a researcher.

Do Institutional Participatory Projects Contribute to the Development of Political Capabilities?

Participation usually sets off from the bottom up, taking the form of more or less enduring forms of collective action with varying degrees of infl uence. However, a number of projects have been launched by political institutions in the last decades with a view to engaging citizens in public affairs and developing their democratic habits, as well as those of the administration. This paper analyses the political qualifying capacity of the said projects, i.e. whether participating in them qualifi es individuals to behave as active citizens; whether these projects foster greater orientation towards public matters, intensify (or create) political will, and provide the necessary skills and expertise to master this will. To answer these questions, data from the comparative analysis of fi ve participatory projects in France and Spain are used, shedding light on which features of these participatory projects contribute to the formation of political subjects and in which way. Finally, in order to better understand this formative dimension, the formative capacity of institutional projects is compared with the formative dimension of other forms of participation spontaneously developed by citizens.

Role of NleH, a type III secreted effector from attaching and effacing pathogens, in colonization of the bovine, ovine, and murine gut

The human pathogen enterohemorrhagic Escherichia coli (EHEC) O157:H7 colonizes human and animal gut via formation of attaching and effacing lesions. EHEC strains use a type III secretion system to translocate a battery of effector proteins into the mammalian host cell, which subvert diverse signal transduction pathways implicated in actin dynamics, phagocytosis, and innate immunity. The genomes of sequenced EHEC O157:H7 strains contain two copies of the effector protein gene nleH, which share 49% sequence similarity with the gene for the Shigella effector OspG, recently implicated in inhibition of migration of the transcriptional regulator NF-kappaB to the nucleus. In this study we investigated the role of NleH during EHEC O157:H7 infection of calves and lambs. We found that while EHEC DeltanleH colonized the bovine gut more efficiently than the wild-type strain, in lambs the wild-type strain exhibited a competitive advantage over the mutant during mixed infection. Using the mouse pathogen Citrobacter rodentium, which shares many virulence factors with EHEC O157:H7, including NleH, we observed that the wild-type strain exhibited a competitive advantage over the mutant during mixed infection. We found no measurable differences in T-cell infiltration or hyperplasia in colons of mice inoculated with the wild-type or the nleH mutant strain. Using NF-kappaB reporter mice carrying a transgene containing a luciferase reporter driven by three NF-kappaB response elements, we found that NleH causes an increase in NF-kappaB activity in the colonic mucosa. Consistent with this, we found that the nleH mutant triggered a significantly lower tumor necrosis factor alpha response than the wild-type strain.

Cultural valuation and biodiversity conservation in the Upper Guinea forest, West Africa

The cultural valuation of biodiversity has taken on renewed importance over the last two decades as the ecosystem services framework has become widely adopted. Conservation initiatives increasingly use ecosystem service frameworks to render tropical forest landscapes and their peoples legible to market-oriented initiatives such as REDD+ and biodiversity offsetting schemes. Ecosystem service approaches have been widely criticized by scholars in the social sciences and humanities for their narrow focus on a small number of easily quantifiable and marketable services and a reductionist and sometimes simplistic approach to culture. We address the need to combine methods from each of the “three cultures” of natural science, quantitative social science, and qualitative social science/humanities in conceptualizing the relationship between cultural valuation and biodiversity conservation. We combine qualitative data with forest inventories and a quantitative index of cultural value to evaluate the relationship between cultural valuation and biodiversity conservation in Upper Guinea forest in Liberia, West Africa. Our study focuses on “sacred agroforests,” spaces that are associated with Mande macro-language speaking groups such as the Loma. We demonstrate that sacred agroforests are associated with different cultural values compared with secondary forests. Although biodiversity and biomass are similar, sacred agroforests exhibit a different species composition, especially of culturally salient species, increasing overall landscape agro-biodiversity. Sacred agroforests are also shaped and conserved by local cultural institutions revolving around ancestor worship, ritual, and the metaphysical conceptual category “salɛ.” We conclude that to understand the relationship between cultural valuation and biodiversity conservation, interpretivist approaches such as phenomenology should be employed alongside positivist ecosystem service frameworks.

Peat Bog Ecosystems: Atmospheric pollution

Peatlands can be damaged by deposition of pollutants from the atmosphere – often termed ‘ acid rain ’ . This results from the release of sulphur and nitrogen pollutants into the atmosphere . Originally associated with the Industrial Revolution, ‘acid rain’ was first described by Robert Angus Smith, a Manchester chemist of the 1800s , whose obser vations were made in close proximity to the peatlands of the South Pennines. Sulphur dioxide (SO 2 ) pollution, which is mainly emitted from coal burning power stations, peaked in the 1970s and has since decreased by over 90% due to emission controls and ch anges in energy supply. N itrogen ous air pollutants have decreased less . N itrogen oxide (NO x ) emissions , which are mainly from vehicle s , have decreased by two thirds since their peak in 1990 , but the decrease in ammonia ( NH 3 ) emissions , which are mainly from intensive livestock farming, is much less certain and may be only about 20%.
