Facemasks have become requisite amid the COVID-19 pandemic. We explore facemasking behaviors, preferences, and attitudes among emerging adults, a “distinct period demographically” within the lifespan. Public opinion polls conducted in May 2020 found that emerging adults were the least compliant when compared to other demographic groups. To understand why, we developed a survey instrument that was administered to a demographically representative quota sample of 1,005 participants. Demographic comparisons revealed that behaviors and attitudes differed significantly by political beliefs, gender, living situation, and race. An exploratory factor analysis revealed six underlying variables: (a) facemask avoidance; (b) concerned adherence (c) vexed faultfinding; (d) statement making; (e) fashion enthusiasm; and (f) hygiene adherence. All factors varied significantly by political affiliation, and in some cases by gender, race, living situation, location, and work/education status. Significant correlations were present between all factors except fashion enthusiasm and vexed faultfinding.

Representations of older age are often reductive in western societies, portrayed as a distinct period of life characterised by social disengagement and physiological decline. Through rich ethnographic accounts developed with older people from Greater Manchester UK, this paper is concerned with how the category of older age is made through representations, and the different ways people encounter and relate to it. In doing so, it disrupts reductive representations by considering how older age is lived. I respond to calls for the incorporation of more-than-representational and affective approaches into the geographic study of older age to advance research on ageing and highlight affect as a useful concept for thinking through difference. The paper is concerned with how older people are represented, with how representations differentially affect and are affected by older individuals, and with how representations of older age are performed and folded into lived accounts. More-than-representational theories offer an understanding of older age that is not pre-given or free-standing, but as something which can emerge, gather and disperse in relation with materialities as well as diffuse atmospheres, affects and emotional resonances.

In this paper the author presents and discusses some of the leading ideas in and behind his book “Kristendommen” (Copenhagen 1986). The concept of ‘history of Christianity’ is defined and compared with that of ‘church history’; but the main emphasis is on a discussion of the advantages and drawbacks of the system of periodization – governed by the principle of relatedness to a ‘civilization’ – which is used in the book. In this connection the notion of ‘Old Europe’ (AD 750/1100-1800) as a coherent and distinct period is particularly emphasized; this entails a discussion of three fundamental and interdependent concepts, valid for the period as a whole: that of ‘internal mission’, that of ‘reform’ and that of ‘clericalism’.

This chapter will show that the Russian conflict was a distinct period in Ireland’s economic history, being a catalyst for Ireland’s post-Famine agricultural recovery. It will be shown that this was caused by the increase in prices and demand which in turn encouraged farmers to alter the distribution of their tillage, export more livestock, hire more labourers and increase the latter’s wages. It will also include various (largely neglected) aspects of industry; showing Irish shipping companies’ comparable astuteness in relation to government contracts, which many entrepreneurs and merchants also eagerly sought, but also the inflexibility of the linen sector and the consequent problems experienced. Finally this chapter will show that the war was, much like the 1850s as a whole, a distinct period in the history of Irish taxation and Irish society’s relationship with its government in London in the nineteenth century and its relationship, or place within, the wider society of the United Kingdom.

ObjectiveWe aimed to explore whether age, period or cohort effects explain the trends and inequalities in ischaemic heart disease (IHD) and cerebrovascular disease (CeVD) mortality in Scotland.MethodsWe analysed IHD and CeVD deaths for 1974–2015 by sex, age and area deprivation, visually explored the data using heatmaps and dotplots and built regression models.ResultsCeVD mortality improved steadily over time while IHD mortality improved more rapidly from the late 1980s. Age effects were evident; both outcomes showed an exponential relationship with age for all except males for IHD in the 1980s and 1990s. The mortality profiles by age became older, although improvement was slower for those aged <50 years for IHD, especially for males, and faster for CeVD in females aged <65 years. Rates were higher, and inequalities greater, among males, especially for IHD. For IHD, increased risk for males over females reduced with age (incidence rate ratio for 41–50 year old males=4.28 (95% CI 4.12 to 4.44) and 1.17 (95% CI 1.16 to 1.18) for 71–80 year olds). Inequalities in IHD mortality by area deprivation persisted over time, increasing from around 10% to around 25% higher risk in the most deprived areas between 1974 and 1986 before declining in absolute terms from around 2000. Inequalities for CeVD increased after the late 1980s.ConclusionsIHD and CeVD mortality in Scotland exhibit age but not recent distinct period or cohort effects. The improvements in mortality rates have been more sustained for CeVD and inequalities greater for IHD.


The Oxford Handbook of the Cold War offers a broad reassessment of the cold war period based on new conceptual frameworks developed in the field of international history. The cold war emerges as a distinct period in twentieth-century history, yet one that should be evaluated within the broader context of global political, economic, social, and cultural developments. This book brings together scholars in cold war history to offer an assessment of the state of the field and identify fundamental questions for future research. The individual chapters in this volume evaluate both the extent and the limits of the cold war's reach in world history. They call into question orthodox ways of ordering the chronology of the cold war and also present new insights into the global dimension of the conflict. Even though each chapter offers a unique perspective, together they show the interconnectedness between cold war and national and transnational developments, including long-standing conflicts that preceded the cold war and persisted after its end, or global transformations in areas such as human rights or economic and cultural globalization. Because of its broad mandate, the volume is structured not along conventional chronological lines, but thematically, offering chapters on conceptual frameworks, regional perspectives, cold war instruments, and cold war challenges. The result is an account of the ways in which the cold war should be positioned within the broader context of world history.

In the early 1990s, scholars largely viewed the height of the glasnost years, 1987 to 1991, to be a culturally and socially distinct period in comparison to the rest of the Soviet epoch. One of the main pieces of evidence employed in this argument was glasnost filmmakers’ novel use of sexuality and nudity. The debate about the cultural significance of the glasnost period, however, has been muted in recent decades. In this reevaluation, I suggest that the misogynistic nature of glasnost filmmakers’ sexuality and nudity depictions actually reflected cultural continuity with previous Soviet eras. This study ultimately challenges the idea of a culturally liberal glasnost period, and supports the case for conservatism throughout the Soviet period.

In many criminal justice systems, there is a clear separation for juvenile and adult defendants. However, those in between, referred to as emerging young adult defendants (ages 18-25 years), are treated as adult defendants despite a growing recognition that emerging adulthood is a distinct period in the life course. The aim of this present study is to investigate the experiences and challenges faced by emerging young adult defendants ( N = 25) in Hong Kong’s adult criminal justice process. Through in-depth semistructured interviews, it was found that emerging young adult defendants demonstrated a lack of understanding regarding their rights and the legal procedures, faced stress in being caught up in the criminal justice process, and were susceptible to influence by others, particularly family members, in making legal decisions. Implications and future directions of study are discussed.

The deinstitutionalization of care for individuals with mental illness is one of the fundamental purposes of Psychiatric Reform in Brazil. Therefore, there is as a central phase, the resizing of the asylum with the argument of the gradual extinction of this circumstance, through the reduction of the number of beds and exchange for therapeutic services that are made available to the community. To identify the repercussions of the deinstitutionalization process for the family member of patients with mental disorders. Scientific articles were searched in the SCIELO, LILACS, BVS-BIREME databases, referring to the theme, with no distinct period. The inclusion criteria for the selection of the sample were: articles published in Portuguese, English, Spanish and European Portuguese that portrayed the theme under study, published and indexed in the referred databases. It can be seen that the greater predominance was given to the qualitative study with 12 articles (80%) due to being researches that mostly interpret qualitative data. It is understood, therefore, that living with the chronic condition becomes, in addition to the difficulties for the family member, a condition that alters the process of being healthy for individuals and groups.

Malware frequently leaves periodic signals in network logs, but these signals are easily drowned out by non-malicious periodic network activity, such as software updates and other polling activity. This paper describes a novel algorithm based on Discrete Fourier Transforms capable of detecting multiple distinct period lengths in a given timeseries. We pair the output of this algorithm with aggregation summary tables that give users information scent about which detections are worth investigating based on the metadata of the log events rather than the periodic signal. A visualization of selected detections enables users to see all detected period lengths per entity, and compare detections between entities to check for coordinated activity. We evaluate our approach on real-world netflow and DNS data from a large organization, demonstrating how to successfully find malicious periodic activity in a large pool of noise and non-malicious periodic activity.
