The concentrated surfactant solutions (10 mM for CTAB, 50 mM for TTAB, and 100 mM for DTAB and OTAB) were injected to the above DNA solutions to reach the final surfactant concentrations for study (Figure 1(b)).
Interestingly, the bimodal size distributions appear again for the surfactant with the shortest chain, OTAB. One peak has a smaller radius, while the other shows a larger size (Figure 2(d)).
This indicates that the OTAB-DNA structure is loose and OTAB cannot compact DNA with high efficiency.
While for OTAB, increasing the concentration does not alter the potential significantly.
Fewer public servants were interviewed in Ontario, since OTAB had been abolished the year before I was able to conduct research in that province.
(10) Elected officials in both Quebec and Ontario created the SDQM and OTAB, placed them under the responsibility of labour ministries, and imposed on the civil servants collaborative relationships with private-sector representatives and community organizations.
In Ontario, on the other hand, the Ministry of Education had swallowed occupational training, courtesy of Harris's downsizing efforts and the abolition of OTAB.
Where Ontarians saw nothing but a failed attempt with OTAB and were ready to try something else, Quebeckers cared a great deal about the potential for provincial autonomy in occupational training that the SQDM represented in their eyes.
Similarly, Klassen provides an intricate internal account of the rise and fall of OTAB. Formed in 1991 by the NDP government of Bob Rae, OTAB had a highly participatory structure that included representation from business, labour, education, and social action groups.
More importantly, two other issues surrounding the birth of OTAB quickly soured relations among government, business, and labour.
Again, Klassen's focus in detailing the birth and death of OTAB is on the internal workings ofthe agency and its precarious values.
Labour is rightly concerned that training not be used by business as an excuse to impose greater "flexibility" on workers, a fact not lost on the Canadian Auto Workers who refused to participate in OTAB. By contrast, businesses want to ensure that training policies do not increase the power of employees and their unions.
