Well-Being Throughout the Senior Years: An Issues Paper on Key Events and Transitions in Later Life

Social Development Canada’s mission is “to strengthen Canada’s social foundations by supporting the well-being of individuals, families and communities and their participation through citizen focused policies, programs and services” (Social Development Canada 2005a). Well-being is a concept that goes beyond good health to encompass physical and mental fitness as well as social fitness (being able to perform one’s social roles and the demands of everyday living adequately). As people age, they experience a number of transitions in their lives. They may retire, change residence, loose a spouse, become a caregiver, and/or develop a health problem or disability. These transitions, especially when they occur around the same time, may impact on their well-being and independence and prevent them from being contributing members of society. This paper summarizes the research on what we currently know about the key events and transitions experienced by seniors, their impacts, and the resources seniors have or need to successfully cope with these events throughout the senior years. It will also review what we know about opportunities, gaps or barriers in accessing social support programs and service delivery designed to assist seniors in coping successfully with adverse events and life transitions. Issues to be considered include availability, access and costs of community support and home health care services. Finally, the paper will attempt to provide potential policy research directions to address current knowledge gaps. This is an extensive literature, and we have limited the scope by focusing on the last 10 years of Canadian research published in Journals and by Statistics Canada. We have favored research based on national studies in this review, though there are many excellent case studies and qualitative studies that add texture to our knowledge. Recognizing that the senior population is a very heterogeneous group, this review will examine (where the research permits) differences by senior life-course stages, and other target groups such as women, the disabled, visible minority, immigrants, Aboriginal peoples, sub-regions, low income, and persons living alone. This review of the literature has shown that while we have basic information about many of the transitions in seniors’ lives, there is very little information about the various life course stages or about various sub groups of society.health and well-being, retirement, marital transitions, care-giving, homecare

Effect of nanoparticle morphologies on signal strength in photoacoustic sensing

Spherical gold nanoparticles with a plasmonic extinction peak at 532 nm and two sizes of star shaped gold nanoparticles with plasmonic extinction peaks at 532 nm and 600 nm were synthesised and introduced into tissue phantoms as exogenous absorbers. The photoacoustic signals generated from the three different nanoparticle morphologies embedded in tissue the phantoms is compared. The effect of nanoparticle concentration on the generated photoacoustic signal strength was also investigated for the spherical nanoparticles. At an excitation laser wavelength of 532 nm, the spherical gold nanoparticles were shown to produce the greatest photoacoustic response

Do Consumers Evaluate New and Existing Fruit Varieties in the Same Way? Modeling the Role of Search and Experience Intrinsic Attributes

Studies have demonstrated the significance of intrinsic sensory attributes on consumer responses to fruits. This paper evaluates the effects on consumers of intrinsic characteristics on new and existing fruit varieties. Fruit consumers were exposed to and tasted a new or an old variety of fruit and rated its intrinsic search and experience attributes, as well as their satisfaction and purchase intention. Results indicated, firstly, that search and experience intrinsic attributes significantly predicted satisfaction and purchase intention. Secondly, the examination of differences between existing and new varieties showed not only a general similarity but also some differences: search attributes played a more relevant role in the purchase intention among existing varieties, and experience qualities were more important for new varieties in terms of satisfaction. It was observed that new varieties were preferred over existing ones. Results are discussed in terms of their implications for consumer behavior study and for managers.Proyecto Corfo "Fortalecimiento del mejoramiento genetico del duraznero mediante la vinculacion internacional y la seleccion asistida" 09PMG-7240 Proyecto Fondef "Sweet Pekeetah: Un modelo tecnologico-comercial para una nueva variedad chilena de fruta" IDeA IT17I006

Same data, different analysts: variation in effect sizes due to analytical decisions in ecology and evolutionary biology

Gould E, Fraser H, Parker T, et al. Same data, different analysts: variation in effect sizes due to analytical decisions in ecology and evolutionary biology. 2023.Although variation in effect sizes and predicted values among studies of similar phenomena is inevitable, such variation far exceeds what might be produced by sampling error alone. One possible explanation for variation among results is differences among researchers in the decisions they make regarding statistical analyses. A growing array of studies has explored this analytical variability in different (mostly social science) fields, and has found substantial variability among results, despite analysts having the same data and research question. We implemented an analogous study in ecology and evolutionary biology, fields in which there have been no empirical exploration of the variation in effect sizes or model predictions generated by the analytical decisions of different researchers. We used two unpublished datasets, one from evolutionary ecology (blue tit, Cyanistes caeruleus, to compare sibling number and nestling growth) and one from conservation ecology (Eucalyptus, to compare grass cover and tree seedling recruitment), and the project leaders recruited 174 analyst teams, comprising 246 analysts, to investigate the answers to prespecified research questions. Analyses conducted by these teams yielded 141 usable effects for the blue tit dataset, and 85 usable effects for the Eucalyptus dataset. We found substantial heterogeneity among results for both datasets, although the patterns of variation differed between them. For the blue tit analyses, the average effect was convincingly negative, with less growth for nestlings living with more siblings, but there was near continuous variation in effect size from large negative effects to effects near zero, and even effects crossing the traditional threshold of statistical significance in the opposite direction. In contrast, the average relationship between grass cover and Eucalyptus seedling number was only slightly negative and not convincingly different from zero, and most effects ranged from weakly negative to weakly positive, with about a third of effects crossing the traditional threshold of significance in one direction or the other. However, there were also several striking outliers in the Eucalyptus dataset, with effects far from zero. For both datasets, we found substantial variation in the variable selection and random effects structures among analyses, as well as in the ratings of the analytical methods by peer reviewers, but we found no strong relationship between any of these and deviation from the meta-analytic mean. In other words, analyses with results that were far from the mean were no more or less likely to have dissimilar variable sets, use random effects in their models, or receive poor peer reviews than those analyses that found results that were close to the mean. The existence of substantial variability among analysis outcomes raises important questions about how ecologists and evolutionary biologists should interpret published results, and how they should conduct analyses in the future
