Robust estimation of bacterial cell count from optical density
- 2020
-
In: Communications Biology. - : Springer Science and Business Media LLC. - 2399-3642. ; 3:1
-
Journal article (peer-reviewed)abstract
- Optical density (OD) is widely used to estimate the density of cells in liquid culture, but cannot be compared between instruments without a standardized calibration protocol and is challenging to relate to actual cell count. We address this with an interlaboratory study comparing three simple, low-cost, and highly accessible OD calibration protocols across 244 laboratories, applied to eight strains of constitutive GFP-expressing E. coli. Based on our results, we recommend calibrating OD to estimated cell count using serial dilution of silica microspheres, which produces highly precise calibration (95.5% of residuals <1.2-fold), is easily assessed for quality control, also assesses instrument effective linear range, and can be combined with fluorescence calibration to obtain units of Molecules of Equivalent Fluorescein (MEFL) per cell, allowing direct comparison and data fusion with flow cytometry measurements: in our study, fluorescence per cell measurements showed only a 1.07-fold mean difference between plate reader and flow cytometry data.

Serial intergenerational learning : Turning absence to presence of grandmothers and mothers in our lives
- 2021
-
Conference paper (peer-reviewed)abstract
- Intergenerational learning is concerned with the learning that occurs between people of different generations. It connects generations through learning by interaction between people. In this paper, we will extend intergenerational learning to include the interaction with past generations as an idea which enriches our current lives. More concretely, we will explore the influence of previous family generations, even after their deaths, to inform our own life worlds, serially, through theirs. We had previously written about a grandmother as well as a mother in private texts. The concept of biographical learning, introduced by Peter Alheit, has been central in adult education research and will constitute a framework for analysis in this paper as it concerns biographies. Through our narrative approach we extended “learning within the lifespan” to beyond it by linking lifetimes to retrospectively examine the effects of historical context on individual experience of aging meaningful to successive generations. From research on older adults learning, we know that the interest in history, in ancestry and for family members tends to increase with age. Based on a general interest for ancestors, we wanted to understand more about a) why we chose to write about a particular relative, b) how this person has influenced our own lives and our view of family history, and c) what this could add to current theories about intergenerational learning, older adults learning and biographical learning. The Alheit framework will guide an analysis of the two stories in order to explore the biographies as a combination of autobiography and biography spanning generations, but the perspective of the story is that of the author even though the content is about the (grand)mother. This holds the potential to deepen the understanding of the meaning of previous lives in our own.

75 years and over in the middle of the COVID-19 pandemic [blog post]
- 2020
-
Other publication (pop. science, debate, etc.)abstract
- Historically high human longevity has resulted in a large population segment aged 75 to 100 in developed countries when the COVID-19 pandemic started in 2020. Since this later life phenomenon is unprecedented, the characteristics of this stage, its role and its status in society are still being socially constructed. However, the pandemic is affecting the public perception of the age group 75 and over as frail, unproductive, consuming valuable health resources and unfairly economically privileged resulting in their being undervalued and misrepresented in public discourse. Thus, the value of life is becoming age dependent and ageism more acceptable. Whether their role and status in society will be altered or enhanced will depend on the social construction process during the months of recovery, so this paper promotes a nuanced discussion to more fairly consider impacts that were specific to them, either in character or in intensity as well as their societal contributions during the pandemic. How countries individually and collectively manage the post pandemic recovery will determine if the later life stage will be impacted negatively or if they will share equally in positive generationally sensitive recovery outcomes.

Competencies in Canada in a globalisation context
- 2012
-
In: Languages in a global world. - Paris : OECD Publishing. - 9789264123243 - 9789264123557 ; , s. 201-227
-
Book chapter (other academic/artistic)abstract
- If language assets provide a comparative advantage in a globalising world, Canada appears well placed. This Canadian case study examines evidence from a country with two official languages and a high proportion of immigrants in the population. Canada’s language wealth has grown as shown by total number of languages spoken and the growth in the number of languages; growth in the proportion who know English and French, and other languages; and the number of people knowing more than one language. Several factors affecting the growth of language wealth in Canada were analysed. Multicultural and bilingual policies have been influential. Though hard to quantify the economic and social benefits to the individual and society, soft evidence was found for such benefits. Allophones who work in both official languages earn a good living while retaining their heritage language. Furthermore, the economic benefit to proficient users of English was shown through multivariate analysis.

Desirable environmental policies for an aging world
- 2023
-
Conference paper (other academic/artistic)abstract
- Unless older people are part of the solution, societies cannot achieve their environmental policy goals. Innovative global policies are essential to consult, develop and implement policies for people all over the world to work individually and collectively to protect the environment.
