Longitudinal qualitative inquiry from a social gerontological perspective can offer unique insights into older adults’ wellbeing and home care service trajectories. This temporal case study of 12 older home care clients analysed 136 interviews over three time points with 53 home care network actors in Manitoba and Nova Scotia. Many clients and families grappled with service changes almost daily, even if the level or type of service appeared officially stable. The pandemic added further disruption, shaping clients’ lives, wellbeing, and relationships, as well as their access to and use of service. Notably, changes in clients’ wellbeing and needs for help were not necessarily straightforward nor always apparent to case coordinators, especially when these were tied to social, emotional, or relational wellbeing, or to clients’ living arrangements, housing, family, and community integration. Findings can enhance theorizing of change for older adults receiving home care and guide equity-informed policy and practice.
This study aimed to assess the frequency of non-sugar sweeteners (NSS) in Brazilian food products and beverages before the implementation of new nutritional labelling legislation. Specifically, we aimed to determine the eligibility of these products to contain NSS according to RDC no. 18/2008, which governed the use of NSS in Brazil during the study period.
Design:
Data were collected from 3335 packaged foods and beverages available in one of Brazil’s top ten supermarket chains, six months following the publication of front-of-package nutrition labelling (FoPNL) and 19 months before the legislation came into force.
Setting:
The study was conducted in the city of Belo Horizonte, state of Minas Gerais, Brazil.
Results:
Our analysis revealed that NSS were present in 12·5 % of the sampled products. Notably, high frequencies of NSS were observed in powder dessert mixes and soya drinks (100 %), gelatin preparations (88·1 %), chewing gum (87·1 %), tea (84·6 %) and carbonated beverages (71·4 %). Furthermore, we found that 82 % of products containing NSS made claims regarding sugar and calorie reduction, with 16·6 % of these claims being inconspicuous. Additionally, 14 % of products targeted controlled sugar intake diets, 0·5 % aimed at sugar-restricted diets and 4 % were ineligible for NSS use. Importantly, the declared NSS content adhered to Brazilian regulatory limits in beverages.
Conclusions:
While most products complied with regulatory standards, our findings highlight the presence of ineligible products and less prominent claims, which may complicate NSS identification for consumers. Continuous monitoring of NSS frequency, especially following the implementation of FoPNL, is essential for ensuring compliance with regulations and promoting informed consumer choices in Brazil.
Do economic sanctions negatively affect democracy and human rights in targeted countries? Although often intended to improve these outcomes, their record of doing so has historically been mixed at best. Most canonical studies cover the 1980s–1990s, but sanctions practice has since undergone major innovations following debates on humanitarian harm. Given this move toward ‘targeted’ sanctions, it stands to reason that sanctions may today be achieving their intended purposes. I take up policy and methodological innovations to re-examine the effects of Western sanctions seeking to improve democracy and human rights from 1990 to 2021. I find that negative effects persist, offering an important update to the empirical literature. Beyond this contribution, I present a template for replicating and extending country-year research in international relations (IR).
This chapter lays out the metatheoretic approach of the book. The focus is on how scientists use experimental work to support compositional hypotheses. It sets aside questions of how scientists might reason in the lab or how scientists might support hypotheses in review articles or textbooks. It brackets questions of the warrant of scientific reasoning. It addresses some of the challenges facing the use of case studies.
This chapter contrasts the theory of singular compositional abduction with Gilbert Harman’s picture of inference to the best explanation. Most notably, Harman’s work is meant to argue that warranted enumerative induction is a special case of inference to the best explanation. It is not, in the first instance, a theory of the scientific interpretation of experimental results. A key element in Harman’s inference to the best explanation is that it is a matter of warranted abductive inference. In trying to understand the scientific interpretation of a single experimental result, one should not assume a priori that an abductive interpretation is warranted. Instead, one should allow that the warrant for some hypothesis only emerges, if it ever does, over the course of a prolonged period of scientific investigation.
Uniform momentum zones (UMZs) are widely used to describe and model the coherent structure of wall-bounded turbulent flows, but their detection has traditionally relied on relatively narrow fields of view which preclude fully resolving features at the scale of large-scale motions (LSMs). We refine and extend recent proposals to detect UMZs with moving-window fields of view by including physically motivated coherency criteria. Using synthetic data, we show how this updated moving-window approach can eliminate noise contamination that is likely responsible for the previously reported, high fractal dimension of UMZ interfaces. By applying the approach to channel flow direct numerical simulation (DNS), we identify a significant number of previously undetected, large-scale UMZ interfaces, including a small fraction of highly linear interfaces with well-defined streamwise inclination angles. We show that the inclination angles vary inversely with the size of the UMZ interfaces and that this relationship can be modelled by the opposing effects of shear-induced inclination and vortex-induced lift-up on hairpin packets. These geometric properties of large-scale UMZ interfaces play an important role in the development of improved stochastic models of wall-bounded turbulence.
Some Hippocratic doctors regarded sleep as a healthy process, and some as a pathological one; some of them struggled to distinguish between hallucinations and nightmares, and some between deep dreamless sleep and total loss of consciousness. This chapter explores how different treatises from the Hippocratic corpus navigated these ambiguities, how they explained different depth of sleep (i.e. different levels of consciousness), and how such understanding relates to their views on mental capacities (which they subsumed in concepts such as phronesis, sunesis, gnômê, and nous).
We extend a classical model of continuous opinion formation to explicitly include an age-structured population. We begin by considering a stochastic differential equation model which incorporates ageing dynamics and birth/death processes, in a bounded confidence type opinion formation model. We then derive and analyse the corresponding mean field partial differential equation and compare the complex dynamics on the microscopic and macroscopic levels using numerical simulations. We rigorously prove the existence of stationary states in the mean field model, but also demonstrate that these stationary states are not necessarily unique. Finally, we establish connections between this and other existing models in various scenarios.
A diachronic look at the contrast between mental illness and impaired consciousness among these ancient doctors shows a trend towards a more compartmentalised idea of these conditions, a stronger notion of disease, and a progressive abstract framing of clinical findings into theoretical classificatory models and comprehensive pathophysiological systems.
In multiparty systems, parties signal conflict through communication, yet standard approaches to measuring partisan conflict in communication consider only the verbal dimension. We expand the study of partisan conflict to the nonverbal dimension by developing a measure of conflict signaling based on variation in a speaker’s expressed emotional arousal, as indicated by changes in vocal pitch. We demonstrate our approach using comprehensive audio data from parliamentary debates in Denmark spanning more than two decades. We find that arousal reflects prevailing patterns of partisan polarization and predicts subsequent legislative behavior. Moreover, we show that consistent with a strategic model of behavior, arousal tracks the electoral and policy incentives faced by legislators. All results persist when we account for the verbal content of speech. By documenting a novel dimension of elite communication of partisan conflict and providing evidence for the strategic use of nonverbal signals, our findings deepen our understanding of the nature of elite partisan communication.
