Reducing risks from E. coli 0157 on the organic farm
(Canadian Centre for Sustainable Agriculture, Saskatoon, Saskatchewan., 2001)E.coli 0157 is a bacterial pathogen of the human intestinal tract which is carried in certain species of livestock and wildlife without ill effect. Such organisms are termed zoonotics. Various types of Campylobacter and ... -
Reflections on the failure of traditional fisheries management
(2017-01)A traditional fisheries management or fish stock assessment takes a Lamarckian-like instructive view of fisheries science that involves an inductive monism. Its invalid inductive arguments have no problem solving capacity ... -
Reflections on the failure of traditional fisheries management
(2016-06-03)A traditional fisheries management or fish stock assessment takes a Lamarckian-like instructive view of fisheries science. Its invalid inductive arguments have no problem solving capacity and are responsible for the collapse ... -
Regeneration of Forest and Barrens after the Spryfield Fire
(2010-09-02)This set of annotated photos illustrates the regeneration of vegetation over 16 months after an intense fire that swept through forest and barrens in the vicinity of Spryfield, Nova Scotia on April 30/May 1 of 2009. The ... -
Salt marshes in Nova Scotia: a status report of the Saltmarsh Working Group
(Institute of Resource and Environmental Studies and Department of Biology, Dalhousie University, 1981-06-01)There are approximately 80,000 acres of salt marsh land in Nova Scotia of which approximately 43,000 acres have been dyked for agricultural use. Salt marsh lands have served as major producers of food in estuarine regions. ... -
Scientific parameterization and its validation: comparing the universal models of fisheries economics with the invalid modeling of stock assessment
(2008-09-22)Here I compare the valid parameterization of fisheries economics with the data-fitted parameters of a stock assessment’s modeling, invalid models whose predictions cannot be falsified (which is another way of saying ... -
Seven case studies in sustainable agriculture
(Science Council of Canada, Ottawa, 1991-05-24)Seven case studies of SA (sustainable agriculture) in Canada were conducted in the late fall/early winter of 1990/91. The primary objective was to provide examples of innovative SA practices that have been implemented by ... -
Some notes on the Aristotelian origin of the distinction between a falsificationist's and verificationist's view of science: together with corrections to my earlier account
(2012-10-31)It has not always been realised that Karl Popper's analytic distinction between the logically stronger falsificationist's view of science and the logically weaker verificationist's and inductivist's view of science is a ... -
The sound management of a fishery as a social engineering: applying Karl Popper's demarcation criterion to an Area 2 stock of Pacific halibut
(2014-10-23)The Newfoundland fishery for Atlantic cod was once the largest cod fishery in the World. In the early 1990s this fishery formed part of an Atlantic Canadian groundfish fishery collapse that has become one of the World's ... -
The State-Spaced Integrated assessment model for Newfoundland's 'northern cod' as a stock assessment model that fails to distinguish between normative and natural laws
(2018-02-06)Stock assessment models for Atlantic Canada's groundfish fisheries such as Noel Cadigan's recent State-Spaced Integrated assessment model for Newfoundland's 'northern cod' involve single premised inductive arguments that ... -
Systems for sustainable agriculture: approaches, tradeoffs and needs
(Canadian Centre for Sustainable Agriculture, Saskatoon, Saskatchewan, 2001)All systems of agriculture practiced today can be seen as having a potential for improvement and contributing toward a more sustainable agriculture. The major differences in approach and in the types of services needed to ... -
Water quality measurements on Williams Lake and Colpitt Lake (Halifax, N.S.) Dec 7-13, 2015 with reference to possible impacts of road salt
(Williams Lake Conservation Company, 2016-01-06)Concerns have been expressed by the Williams Lake Conservation Company (WLCC) about possible effects of renewed salting of roads close to Williams Lake on water quality of the lake. Such salting was replaced by sand and ... -
What is a fish stock assessment? Is it a sound method? Can it be used to manage a commercial fishery?
(2015-09)Under Karl Popper's non-inductive theory of method arguments are never carried from data to advice as in a fish stock assessment. That is: a distinction or 'demarcation' has to be made between (i) a Lamarckian-like inductive ... -
Why an ecosystem approach is the wrong paradigm for the next stage of fisheries management
(2006-09-13)Scientists from the Department of Fisheries and Oceans (DFO) manage groundfish stocks by collecting biomass measurements that are used to provide scientific advice on catch limits. Clearly, if the data is uncertain or ...
