Explanatory role of sociodemographic, clinical, behavioral, and social factors on cognitive decline in older adults with diabetes

Background The aim of the study was to examine the explanatory role of sociodemographic, clinical, behavioral, and social factors on racial/ethnic differences in cognitive decline among adults with diabetes. Methods Adults aged 50+ years with diabetes from the Health and Retirement Survey were assessed for cognitive function (normal, mild cognitive impairment [MCI], and dementia). Generalized estimating equation (GEE) logistic regression models were used to account for repeating measures over time. Models were adjusted for sociodemographic (gender, age, education, household income and assets), behavioral (smoking), clinical (ie. comorbidities, body mass index), and social (social support, loneliness, social participation, perceived constraints and perceived mastery on personal control) factors. Results Unadjusted models showed non-Hispanic Blacks (NHB) and Hispanics were significantly more likely to progress from normal cognition to dementia (NHB OR: 2.99, 95%CI 2.35–3.81; Hispanic OR: 3.55, 95%CI 2.77–4.56), and normal cognition to MCI (NHB OR = 2.45, 95%CI 2.14–2.82; Hispanic OR = 2.49, 95%CI 2.13–2.90) compared to non-Hispanic Whites (NHW). Unadjusted models for the transition from mild cognitive decline to dementia showed Hispanics were more likely than NHW to progress (OR = 1.43, 95%CI 1.11–1.84). After adjusting for sociodemographic, clinical/behavioral, and social measures, NHB were 3.75 times more likely (95%CI 2.52–5.56) than NHW to reach dementia from normal cognition. NHB were 2.87 times more likely (95%CI 2.37–3.48) than NHW to reach MCI from normal. Hispanics were 1.72 times more likely (95%CI 1.17–2.52) than NHW to reach dementia from MCI. Conclusion Clinical/behavioral and social factors did not explain racial/ethnic disparities. Racial/ethnic disparities are less evident from MCI to dementia, emphasizing preventative measures/interventions before cognitive impairment onset are important.

Health- or Environment-Focused Text Messages as a Potential Strategy to Increase Plant-Based Eating among Young Adults: An Exploratory Study

Previous plant-based diet (PBD) adoption strategies have primarily focused on health rather than environmental rationale and meat reduction rather than plant-based protein promotion. In this study, we explored the effect of a theory-informed text-message intervention on dietary intentions and behaviors in young adult omnivores and the potential explanatory role of PBD beliefs, subjective norm, self-efficacy, moral norm, and health and environmental values. Participants completed baseline questionnaires and reported dietary intake before being randomly assigned to receive 2–3 health- or environment-focused text messages per week for eight weeks and then repeated baseline assessments. Although we did not see significant changes in meat or plant protein intake, we did observe a marked decrease in intentions to consume animal protein and a marginal increase in fruit and vegetable consumption intention. We identified subjective norms, self-efficacy, and moral satisfaction as the strongest predictors of changes in intention to consume animal or plant protein. Although few group differences were observed, those receiving environment-focused text messages experienced a greater change in values and were more likely to increase vegetable intake. Messages that improve sustainability awareness and provide practical adoption strategies may be part of an effective strategy to influence PBD intake among young adults.

The pragmatic use of metaphor in empirical psychology

Metaphors of mind and their elaboration into models serve a crucial explanatory role in psychology. In this article, an attempt is made to describe how biology and engineering provide the predominant metaphors for contemporary psychology. A contrast between the discursive and descriptive functions of metaphor use in theory construction serves as a platform for deliberation upon the pragmatic consequences of models derived therefrom. The conclusion contains reflections upon the possibility of an integrative interdisciplinary psychology.

Family, Work, Collegial, and Emotional Influences on Problem-Focused Voice Behaviors

This study details the unexplored connection between employees’ exposure to family incivility and voice behavior to pinpoint organization problems, considering the mediating role of their work engagement and the moderating role of their emotion sharing with colleagues in this connection. Survey data obtained from employees who work in the banking sector reveal that a critical reason rude treatment by family members keeps employees from expressing their opinions about organizational shortcomings at work is that they exhibit limited positive work energy. This explanatory role of work engagement is less salient though when employees can draw on the relational resource of emotion sharing. For organizational change professionals, this study accordingly showcases a core explanation, thwarted work engagement, by which family-related hardships prevent employees from undertaking productive problem-focused voice activities, and it explicates how this mechanism can be subdued if the work environment encourages employees to express personal feelings openly to their peers.

In defence of constitutive rules

Although the notion of constitutive rule has played an important role in the metaphysical debate in social and legal philosophy, several authors perceive it as somewhat mysterious and ambiguous: the idea of a specific kind of rules that are supposed to be “magically” constitutive of reality seems suspicious, more a rationalistic fiction than a genuine explanation. For these reasons, reductionist approaches have been put forward to deflate the explanatory role of this notion. In this paper, I will instead try to defend constitutive rules. My thesis is that the notion of constitutive rule is explanatorily helpful because it gives a complete account of an important phenomenon in the social and legal domain, namely, that of artifactual entities endowed with statuses that can have emergent normative properties. Conceiving of these entities as rule-constituted artifacts is an important part of what H. L. A. Hart called “the internal point of view” toward law, and for this reason constitutive rules should be included in an explanation of that point of view as an integral part of the life of institutions. The structure of my argument will be as follows. First, I will provide an example of an important phenomenon in the internal point of view, namely, the fact that individuals can have normative reactions not about the specific regulation of an institution but about its underlying purpose and rationale—what in the legal domain is called the ratio of a norm. Then I will identify two reductionistic approaches on constitutive rules. The first approach is exemplified by Brian Epstein’s idea that the phenomena explained by constitutive rules are better explained in terms of metaphysical (grounding/anchoring) relations. The second kind of reductionism is instead exemplified by the idea (held by several authors, among whom Alf Ross, Riccardo Guastini, Frank Hindriks, and Francesco Guala) that the phenomena explained by constitutive rules can be accounted for in terms of regulative rules plus a certain terminology. I will try to show that neither of these approaches can explain normative reactions to the ratio of an institution from an internal point of view: While the first cannot explain the fact that the reaction is strongly normative, the second cannot explain the fact that the reaction is about the ratio of a normative entity. Constitutive rules can instead explain both things and should be preserved as an important notion for the analysis of institutional ontology. By way of constitutive rules we create something: immaterial, rule-based institutional artifacts that can have emergent normative properties.

Why Conceptual Engineers Should Not Worry About Topics

This paper argues for explanatory eliminativism about topics (and cognates, such as subject matters) relative to the domain of conceptual engineering. It has become usual to think that topics serve an important explanatory role in theories of conceptual engineering, namely, to determine the limits of revision. I argue, first, that such limits can be understood either as the normative limits pertaining to the justification of conceptual engineering, as the metaphysical limits pertaining to the identity of the concepts in question, or as the terminological limits pertaining to usage of the original terminology. Second, I argue that the metaphysical reading is disputable as a theory of concepts and inconsequential for conceptual engineers, and that neither of the two leading accounts of topics that have been presented in the literature—the samesaying account and functionalism—determine the limits of revision in either of the two remaining senses. In the absence of more promising competitors, I conclude that there is no theoretical role for topics to play in theories of conceptual engineering. An upshot of my argument is that conceptual engineers should stop worrying about things like topic (dis)continuity, and instead shift their attention to the issues that really matter for justifying conceptual revisions or replacements, making terminological choices, and underpinning conceptual engineering with a theory of concepts.

Forms as Forces: The Causal Regime of Morphology in Biology

Traditionally, morphology is seen merely as an auxiliary subdiscipline of biology and other fields. Allegedly, it does not provide explanations for phenomena but merely describes forms as a preliminary step in their analysis. Here, the view is defended that forms, and hence morphology, can also take over an important explanatory function and even, ultimately, constitute the explanatory level fundamental to biology as a distinct science. According to this thesis, the form of organisms and their parts provide the only specifically biological causal factors. Nothing but the form, the specific spatial arrangement of matter, determines the peculiarity of organisms’ ways of being. Therefore, biological explanation must start from specific structures. These structures provide the respective boundary conditions for harnessing the general laws of nature, thus determining their trajectory. Ultimately, then, forms play the most fundamental explanatory role in biology.

Canonul occidental din Istoria literaturii române contemporane: 1990-2020 de Mihai Iovănel

This paper focuses on the strategies enacted by Mihai Iovănelʼs History in order to map the transnational interactions of contemporary Romanian literature. Since Iovănel emphasizes that, starting with the 2000s, the Romanian writers define themselves mainly through the global networks in which they try to integrate, this article aims to analyse: a) the canonical function acquired by the local references to World Literature; b) their explanatory role compared to the one played by the closed circuit of the so-called “intra-national” comparisons; c) the theoretical legitimacy of the “transnational canon” projected by Iovănel in the epilogue of his History.

Lifestyle decisions and climate mitigation: current action and behavioural intent of youth

Youth carry the burden of a climate crisis not of their making, yet their accumulative lifestyle decisions will help determine the severity of future climate impacts. We surveyed 17–18 year old’s (N = 487) to establish their action stages for nine behaviours that vary in efficacy of greenhouse gas emission (GGE) reduction and the explanatory role of climate change (CC) knowledge, sociodemographic and belief factors. Acceptance of CC and its anthropogenic origins was high. However, the behaviours with the greatest potential for GGE savings (have no children/one less child, no car or first/next car will be electric, eat less meat) have the lowest uptake. Descriptive normative beliefs predicted intent to adopt all high-impact actions, while environmental locus of control, CC scepticism, knowledge of the relative efficacy of actions, religiosity and age were predictive of action stage for several mitigation behaviours (multinomial logistic regression). These findings inform policy and communication interventions that seek to mobilise youth in the global climate crisis response.

Models, structures, and the explanatory role of mathematics in empirical science

Are there genuine mathematical explanations of physical phenomena, and if so, how can mathematical theories, which are typically thought to concern abstract mathematical objects, explain contingent empirical matters? The answer, I argue, is in seeing an important range of mathematical explanations as structural explanations, where structural explanations explain a phenomenon by showing it to have been an inevitable consequence of the structural features instantiated in the physical system under consideration. Such explanations are best cast as deductive arguments which, by virtue of their form, establish that, given the mathematical structure instantiated in the physical system under consideration, the explanandum had to occur. Against the claims of platonists such as Alan Baker and Mark Colyvan, I argue that formulating mathematical explanations as structural explanations in this way shows that we can accept that mathematics can play an indispensable explanatory role in empirical science without committing to the existence of any abstract mathematical objects.
