Abstract Twin studies function as natural experiments that reveal political ideology’s substantial genetic roots, but how does that comport with research showing a largely nonideological public? This study integrates two important literatures and tests whether political sophistication – itself heritable – provides an “enriched environment” for genetic predispositions to actualize in political attitudes. Estimates from the Minnesota Twin Study show that sociopolitical conservatism is extraordinarily heritable (74%) for the most informed fifth of the public – much more so than population-level results (57%) – but with much lower heritability (29%) for the public’s bottom half. This heterogeneity is clearest in the Wilson–Patterson (W-P) index, with similar patterns for individual index items, an ideological constraint measure, and ideological identification. The results resolve tensions between two key fields by showing that political knowledge facilitates the expression of genetic predispositions in mass politics.

Party Polarization

Citizens are political simpletons—that is only a modest exaggeration of a common characterization of voters. Certainly, there is no shortage of evidence of citizens' limited political knowledge, even about matters of the highest importance, along with inconsistencies in their thinking, some glaring by any standard. But this picture of citizens all too often approaches caricature. This book brings together leading political scientists who offer new insights into the political thinking of the public, the causes of party polarization, the motivations for political participation, and the paradoxical relationship between turnout and democratic representation. These studies propel a foundational argument about democracy. Voters can only do as well as the alternatives on offer. These alternatives are constrained by third players, in particular activists, interest groups, and financial contributors. The result: voters often appear to be shortsighted, extreme, and inconsistent because the alternatives they must choose between are shortsighted, extreme, and inconsistent.

The Impact

IntroductionThe emergence of the novel respiratory SARS-CoV-2 and subsequent COVID-19 pandemic have required rapid assimilation of population-level data to understand and control the spread of infection in the general and vulnerable populations. Rapid analyses are needed to inform policy development and target interventions to at-risk groups to prevent serious health outcomes. We aim to provide an accessible research platform to determine demographic, socioeconomic and clinical risk factors for infection, morbidity and mortality of COVID-19, to measure the impact of COVID-19 on healthcare utilisation and long-term health, and to enable the evaluation of natural experiments of policy interventions.Methods and analysisTwo privacy-protecting population-level cohorts have been created and derived from multisourced demographic and healthcare data. The C20 cohort consists of 3.2 million people in Wales on the 1 January 2020 with follow-up until 31 May 2020. The complete cohort dataset will be updated monthly with some individual datasets available daily. The C16 cohort consists of 3 million people in Wales on the 1 January 2016 with follow-up to 31 December 2019. C16 is designed as a counterfactual cohort to provide contextual comparative population data on disease, health service utilisation and mortality. Study outcomes will: (a) characterise the epidemiology of COVID-19, (b) assess socioeconomic and demographic influences on infection and outcomes, (c) measure the impact of COVID-19 on short -term and longer-term population outcomes and (d) undertake studies on the transmission and spatial spread of infection.Ethics and disseminationThe Secure Anonymised Information Linkage-independent Information Governance Review Panel has approved this study. The study findings will be presented to policy groups, public meetings, national and international conferences, and published in peer-reviewed journals.

Presidential Debate

One mechanism by which citizens learn about candidates and issues is through watching presidential debates. Some scholars have raised concerns that these events, however, disproportionately benefit those already high in political knowledge more so than others with lesser knowledge levels. We hypothesize that knowledge begets knowledge because it prompts a constructive cognitive process that results from elaboration and reflection. We test this hypothesis in an experiment that also considers whether issue priming could help mitigate the deficit that those lower in political sophistication have when viewing campaign events. Participants ( N = 543) watched a 9-minute segment focusing on economic issues drawn from the first 2020 presidential debate between President Donald Trump and former Vice President Joseph Biden. Half of the participants were randomly assigned to an issue priming condition and viewed the debate segment after reading a narrative text on economic policy, and the other half read an unrelated text. The study presents a model that reveals the following: (a) cognitive elaboration mediates the relationship between prior political knowledge and learning from a campaign event, (b) providing citizens with background issue–related knowledge produces a similar elaborative effect as did preexisting political knowledge, and (c) participants demonstrate greater political opinion articulation following this enhanced elaboration leading to more learning. The implications for cultivating a knowledgeable democratic electorate are discussed.

Abstract This article provides an overview of the public health approach to suicide in Ireland. The authors provide detail on the current suicide prevention strategy in Ireland, Connecting for Life, which is a whole-of-government, systemic, multicomponent national strategy. As the strategy enters its final extended phase of implementation over the period 2020–2024, the public health elements of Connecting for Life are presented, including the population level and more targeted approaches. The findings of an interim review of the strategy are discussed, in addition to the local and national implementation structures which are in place to assist implementation and monitoring of the strategy.

Political Sophistication

This dissertation is concerned with the concept of political sophistication, referring to the extent and organization of a person’s stored political cognition (Luskin 1987).Available empirical evidence on the levels of political sophistication in mass publics comes almost exclusively from the United States and point to two broad conclusions: First, systematic empirical research has demonstrated that political information in the mass public is particularly low (Converse 1964, Delli Carpini and Keeter 1996). Citizens lack basic knowledge over political affairs. Time and again empirical studies have systematically showed that citizens in the United States and elsewhere fall short of passing even the most rudimentary political knowledge tests. This finding that was first illustrated by the Michigan school in the early 1960s (Campbell et al. 1960) resulted in a wide pessimism over the meaning of public opinion and even of representative democracy (Inglehart 1985).The second broad conclusion is that the politically sophisticated and unsophisticated differ: Political sophisticates have the cognitive capacity to translate their deeper held political values and predispositions into consistent political attitudes (Zaller 1992). They are able to use their political knowledge in order to make informed vote choices in the sense that they accurately adjust their political positions to the parties’ platforms (Delli Carpini and Keeter 1996, Lau and Redlawsk 1997, 2006). What is more, they are more likely to participate in elections and other political activities and are less susceptible to political propaganda (Delli Carpini and Keeter 1996).However the idea that political sophistication matters for the quality of the public’s political decision-making has met strong theoretical and methodological criticism by the ‘low information rationality’ perspective (Popkin 1991, Lupia 1994,Graber 2001). This group of theories argues that politically inattentive citizens can form their political judgment on the basis of heuristics that allow them to make reasonable choices reflecting their predispositions and interests even though they lack political knowledge.The principal aims of this thesis are: a)to compare different measurement perspectives on political sophistication and assess their methodological potential especially in regard with comparative research on political knowledgeb)to explore the extent to which the pattern of ignorance that has been repeatedly highlighted in the American literature is an internal characteristic of political behavior stemming from the low expected utility of acquiring political information or it is subject to particular cultural and systemic characteristics. To this direction I use Greece as a case study by undertaking an analytical survey of political sophistication, one of the very few that have been conducted across the Atlantic.c)The third aim is to investigate the determinants of political sophistication and especially the potential of the mass media in political learning and in the context of the Greek political and media system.d)d) Finally this thesis addresses the unresolved question concerning the differences in quality of political decisions between the political sophisticated and unsophisticated layers of the public by evaluating the explanatory potential of two competing theories (political sophistication v. low information rationality) in the multi-party political environment of Greece

Risk Charts

Despite the wide improvement of diagnostic techniques and the introduction of effective pharmacological and instrumental therapeutic strategies aimed to the treatment of cardiovascular diseases, their incidence and lethality are still elevated, with economic implications increasingly less sustainable by the public medical systems. The modern practice of cardiovascular prevention requires, thus, that diagnostic and therapeutic interventions, both at population level and on the single patient, should be more and more precise, effective, and appropriate. From this point of view, a correct global cardiovascular risk stratification assumes a preponderant relevance, in order to allow an adequate therapeutical response. For this purpose several work instruments, as risk charts and guidelines, namely dedicated to arterial hypertension and dyslipidemias, were developed and offered to clinicians interested in cardiovascular prevention. The aim of this review is to illustrate, in synthesis, those instruments, aiming to facilitate their implementation, thus reducing the actual gap between theoretical indications and the real world.

AbstractObjectivesTo estimate population health outcomes under delayedsecond dose versus standard schedule SARS-CoV-2 mRNA vaccination.DesignAgent-based modeling on a simulated population of 100,000 based on a real-world US county. The simulation runs were replicated 10 times. To test the robustness of these findings, simulations were performed under different estimates for single-dose efficacy and vaccine administration rates, and under the possibility that a vaccine prevents only symptoms but not asymptomatic spread.Settingpopulation level simulation.Participants100,000 agents are included in the simulation, with a representative distribution of demographics and occupations. Networks of contacts are established to simulate potentially infectious interactions though occupation, household, and random interactionsInterventionswe simulate standard Covid-19 vaccination, versus delayed-second-dose vaccination prioritizing first dose. Sensitivity analyses include first-dose vaccine efficacy of 70%, 80% and 90% after day 12 post-vaccination; vaccination rate of 0.1%, 0.3%, and 1% of population per day; assuming the vaccine prevents only symptoms but not asymptomatic spread; and an alternative vaccination strategy that implements delayed-second-dose only for those under 65 years of age.Main outcome measurescumulative Covid-19 mortality over 180 days, cumulative infections and hospitalizations.ResultsOver all simulation replications, the median cumulative mortality per 100,000 for standard versus delayed second dose was 226 vs 179; 233 vs 207; and 235 vs 236; for 90%, 80% and 70% first-dose efficacy, respectively. The delayed-second-dose strategy was optimal for vaccine efficacies at or above 80%, and vaccination rates at or below 0.3% population per day, both under sterilizing and non-sterilizing vaccine assumptions, resulting in absolute cumulative mortality reductions between 26 and 47 per 100,000. The delayed-second-dose for those under 65 performed consistently well under all vaccination rates tested.ConclusionsA delayed-second-dose vaccination strategy, at least for those under 65, could result in reduced cumulative mortality under certain conditions.

The Comparative Study

This chapter empirically tests the expectation that compulsory voting moderates the effects of orientations toward democracy on political attitudes, behavior, and sophistication. It first employs cross-national survey data from the AmericasBarometer and the Comparative Study of Electoral Systems to estimate multilevel models. It also uses cross-cantonal data from the Swiss Election Study, and novel survey data from Argentina collected for this book. The analyses of the Swiss and Argentine data leverage age-based thresholds in the application of compulsory voting with discontinuity models. Results suggest that, in line with the predictions of the theory advanced in Chapter 3, compulsory voting polarizes behavior and attitudes, and broadens gaps in political sophistication levels, among those with negative and positive orientations toward democracy.

Physiological Dysregulation

Although old age is readily recognizable, methods to define and measure the underlying biological processes are much less amenable to study. For this reason, life expectancy has been widely used as a surrogate measure of ageing, as well as to monitor economic progress at national and regional levels. It is generally acknowledged that lifespan is a constitutional feature of the human phenotype, and twin studies have indicated that 25–33 per cent of the variance in human longevity is genetic in origin. External factors including lifestyle can also exert a major influence, as illustrated by the current mean life expectancies of 79 and 86 years for males and females in Japan, whereas the comparable figures for Botswana are 35 and 33 years, respectively. The importance of genetic inheritance as a determinant of extended survival has been illustrated by population level studies in Okinawa, an island prefecture of southern Japan with a very high prevalence of long-lived individuals. On the island, the mortality rates of the male and female siblings of centenarians were approximately half those of birth cohort-matched, non-centenarian siblings. These findings parallel an earlier study of the family of Jeanne Calment, who died in France in 1997 aged 122 years. Of her 55 relatives, 24 per cent had lived to >80 years compared to just 2 per cent of a matched control group. However, it remains unclear whether the enhanced lifespan of individuals who exhibit above average longevity is due to a slowing of the overall ageing process or is primarily associated with resistance to major life-threatening pathologies. The concept of an ‘allostatic load’, potentially involving the neuroendocrine, sympathetic nervous, immune and cardiovascular systems, and metabolic pathways, has been advanced to describe the lifetime costs of adapting to physical and psychological stresses. According to this hypothesis, while the actions of biological mediators of stress can be initially beneficial to health, chronic stimulation results in regulatory imbalance and subsequent pathophysiological changes. Empirical studies have indicated increased physiological dysregulation and functional decline at >70 years of age, which would imply that predicted global increases in the numbers of older persons will be accompanied by disproportionately larger groups of individuals with major age-related pathologies.

AbstractIn 1984, Hrubec and Robinette published what was arguably the first review of the role of twins in medical research. The authors acknowledged a growing distinction between two categories of twin studies: those aimed at assessing genetic contributions to disease and those aimed at assessing environmental contributions while controlling for genetic variation. They concluded with a brief section on recently founded twin registries that had begun to provide unprecedented access to twins for medical research. Here we offer an overview of the twin research that, in our estimation, best represents the field has progress since 1984. We start by summarizing what we know about twinning. We then focus on the value of twin study designs to differentiate between genetic and environmental influences on health and on emerging applications of twins in multiple areas of medical research. We finish by describing how twin registries and networks are accelerating twin research worldwide.
