Meromictic lakes provide a physically stable environment in which proxies for potentially harmful cyanobacteria are exceptionally well-preserved in the sediments. In Sunfish Lake, a meromictic lake that has recently become the focus of citizen concern due to the apparent rise in cyanobacteria blooms, we used a multi-proxy paleolimnological approach pairing novel spectral (i.e., VNIRS) and molecular (i.e., qPCR) assessment tools to explore long-term cyanobacteria trends. We hypothesized that climate change over the past 50 years altered the Sunfish Lake environment to favour cyanobacteria dominance, resulting in an increased incidence of bloom events. Spectral and genetic results aligned to reveal an unprecedented abundance of cyanobacteria in modern times and coincided with warmer and wetter climatic conditions in the region. Our findings offer evidence for climate-driven shifts in cyanobacteria abundance and suggest that a shift towards warmer and wetter conditions supports the rise of cyanobacteria in lakes.

Intense research for more than three decades expelled the view that neonates do not experience pain. The aim of this survey was to investigate whether the Greek physicians involved in neonatal intensive care have changed their perceptions regarding neonatal pain, adapting their management practices to the knowledge that have emerged in the past 20-years. This study is a survey conducted at two time-points, 20 years apart. Anonymous questionnaires were distributed to 117 and 145 physicians working in neonatal intensive care units (NICUs) all over Greece in years 2000 and 2019, respectively. The response rate was 90.6 and 80.7% in 2000 and 2019, respectively. All respondents, at both time-points, believed that neonates experience pain, which has serious acute and long-term consequences, while the vast majority considered analgesia-sedation (A-S) during painful interventions as obligatory. Utilization of NICU protocols and pain assessment tools remained low although increased significantly between 2000 and 2019. The use of systemic A-S postoperatively was high at both time-points, while its implementation in infants subjected to prolonged pain, specifically mechanical ventilation, increased significantly by 2019. Systemic or local analgesia for acute procedural pain was used by lower proportions of physicians in 2019, except for the tracheal intubation. In contrast, the use of sweet solutions and non-pharmacological measures prior to or during bedside procedures significantly increased over time. Opioid administration significantly increased, while a shift from morphine to fentanyl was observed. International literature and perinatal–neonatal congresses were stated as the main sources of updating physicians' knowledge and improving management practice on neonatal pain prevention and treatment. In conclusion, Greek NICU-physicians' perceptions that neonates can experience pain with potentially serious acute and long-term consequences remained strong over the past 20 years. Although physicians' practices on neonatal pain management improved, they are still suboptimal, while significant differences exist among centers. Continuing education, globally accepted management protocols, and readily applied pain assessment tools would further improve the management of procedural pain and stress in neonates.

Recent literature has reconstructed estimates of wealth and income inequality for a range of preindustrial, mostly European, societies covering medieval and early modern times, occasionally reaching back to antiquity and even prehistory. These estimates have radically improved our knowledge of distributive dynamics in the past. It now seems clear that in the period circa 1300–1800, inequality of both income and wealth grew almost monotonically almost everywhere in Europe, with the exception of the century-long phase of inequality decline triggered by the Black Death of 1347–52. Regarding the causes of inequality growth, recent literature ruled out economic growth as the main one. Other possible factors include population growth (also as mediated by inheritance systems) and especially regressive fiscal institutions (also as connected to the unequal distribution of political power). The recently proposed theoretical framework of the inequality possibility frontier (IPF) lends a better understanding of the implications of the reconstructed trends. This article concludes by showing how connecting preindustrial trends to modern ones changes our perception of long-term inequality altogether. (JEL D31, D63, N33)

This chapter tells the story of how ideas of resilience emerged as the go-to futureproofing idea in the early years of the twenty-first century. It has a long history dating back to pre-modern times and extends through the advancement of associated ideas of ‘risk’. Tracing the deeper development of changes in the way hazards and disasters have been historically viewed, and vulnerability felt, by human civilisations of the past, is vital to understanding the roots of contemporary dilemmas and the growing influence of ideas of resilience in the twenty-first century. There are long-term historical processes that have defined the contours of society and the slowly evolving structures that collectively symbolise how the need to be able to account for hazards and disasters has reshaped our world. As such, this is a story of religious versus scientific explanations, and of enhancing the ability to control the future through better knowledge about what is in store and the likelihood of certain events occurring.

The whole world is currently struggling with one of the most disastrous pandemics to hit in modern times – Covid-19. Individual national governments, the WHO and worldwide media organisations are appealing for humanity to universally stay at home, to limit contact and to stay safe in the ongoing fight against this unseen threat. Economists are concerned about the devastating effect this will have on the markets and possible outcomes. One of the countries suffering from potential destruction of this situation is Poland. In this article we will explain how difficult internal energy transformation is, considering the long-term crisis associated with the extraction and usage of coal, the European Green Deal and current discussion on increasing the EU 2030 climate ambitions. In the face of an ongoing pandemic, the situation becomes even more challenging with each passing day.

The legacy from Christianity unquestionably lies at the root of Europe, even if not exclusively. It has taken many aspects from the Middle Ages to modern times. If the Christian heritage is diversely understood and accepted within the European Union, the reason is essentially due to its political and religious significance. However, its impact in politics and religion has often been far from negative, if we will consider what secular societies have derived from Christianity: human rights, for example, and a religious affiliation which has been part and parcel of national identity. The Christian legacy has to be acknowledged through a critical analysis which does not deny the truth of the past but should support a European project built around common values.

A model of moisture movement in wood is presented in this paper in a two-dimensional-in-space formulation. The finite-difference technique has been used in order to obtain the solution of the problem. The model was applied to predict the moisture content in sawn boards from pine during long term storage under outdoor climatic conditions. The satisfactory agreement between the numerical solution and experimental data was obtained.

The Naskapi Nation of Kawawachikamach is an Aboriginal community located in northern Quebec near the Labrador Border. Given the region’s rich iron deposits, the Naskapi Nation has considerable experience with major mineral development, first in the 1950s to the 1980s, and again in the past decade as companies implement plans for further extraction. This has raised concerns regarding a range of environmental and socio-economic impacts that may be caused by renewed development. These concerns have led to an interest among the Naskapi to develop a means to track community well-being over time using indicators of their own design. Exemplifying community-engaged research, this paper describes the beginning development of such a tool in fall 2012—the creation of a baseline of community well-being against which mining-induced change can be identified. Its development owes much to the remarkable and sustained contribution of many key members of the Naskapi Nation. If on-going surveying is completed based on the chosen indicators, the Nation will be better positioned to recognize shifts in its well-being and to communicate these shifts to its partners. In addition, long-term monitoring will allow the Naskapi Nation to contribute to more universal understanding of the impacts of mining for Indigenous peoples.

This study provides the analysis of drought conditions of vegetation period in 1982-2014 year in two Lithuanian regions: Kaunas and Telšiai. To identify drought conditions the Standardized Precipitation Index (SPI) was applied. SPI was calculated using the long-term precipitation record of 1982–2014 with in-situ meteorological data. Calculation step of SPI was taken 1 month considering only vegetation period (May, June, July, August, September). The purpose of investigation was to evaluate the humidity/aridity of vegetation period and find out the probability of droughts occurrence under Lithuanian climatic conditions. It was found out that according SPI results droughts occurred in 14.5 % of all months in Kaunas region and in 15.8 % in Telšiai region. Wet periods in Kaunas region occurred in 15.8 %, and in Telšiai region occurrence of wet periods was – 18.8 % from all evaluated months. According SPI evaluation near normal were 69.7 % of total months during period of investigation in Kaunas and respectively – 65.5 % in Telšiai. The probability for extremely dry period under Lithuania climatic conditions are pretty low – 3.0 % in middle Lithuania and 2.4 % in western part of Lithuania.

Concerns that established temple Buddhism in Japan is in a state of crisis have been voiced by priests in various sectarian organizations in recent years. This article shows that there is a very real crisis facing Buddhism in modern Japan, with temples closing because of a lack of support and of priests to run them, and with a general turn away from Buddhism among the Japanese population. In rural areas falling populations have led to many temple closures, while in the modern cities people are increasingly turning away from the prime area in which Japanese people have traditionally engaged with Buddhist temples — the processes of death and their aftermath. Partly this is due to competition from new secular funeral industries, but partly also it is because public perceptions of Buddhism — which has become over-reliant on death rituals in Japan — have become highly negative in modern times. Even practices which have often been seen as areas in which Buddhist temples have been able to attract people — such as pilgrimages — are proving less successful than in the past, contributing further to a sense of crisis that threatens to undermine Buddhism’s roots in Japan.

This paper examines a few of the numerous factors that may have led to increased youth turnout in 2008 Election. First, theories of voter behavior and turnout are related to courting the youth vote. Several variables that are perceived to affect youth turnout such as party polarization, perceived candidate difference, voter registration, effective campaigning and mobilization, and use of the Internet, are examined. Over the past 40 years, presidential elections have failed to engage the majority of young citizens (ages 18-29) to the point that they became inclined to participate. This trend began to reverse starting in 2000 Election and the youth turnout reached its peak in 2008. While both short and long-term factors played a significant role in recent elections, high turnout among youth voters in 2008 can be largely attributed to the Obama candidacy and campaign, which mobilized young citizens in unprecedented ways.
