Long time-series ecological niche modelling using archaeological settlement data: Tracing the origins of present-day landscape

Human activities have shaped the environment since long before the advent of agriculture and resulted in anthropogenic landscapes, which are sometimes perceived as natural, but are clearly shaped by dozens of previous generations. This study is the first to apply ecological niche modelling on a long time-series of archaeological data to illuminate the development of the landscape from the perspective of settlement behaviour and its dependence on environmental conditions. Using a large dataset of evidence of prehistoric settlement activities covering the area of the Czech Republic and spanning 6600 years from the beginning of agricultural prehistory, we analyse to what degree settlement was related to environmental parameters. We quantified the strength of this relation in terms of the predictive power of ecological niche models generated with the MaxEnt method. We observed a significant variability of settlement behaviour over time, but also landscape occupation, which has retained similar general characteristics to now. This shows that settlement strategies were remarkably stable and the presence of previous settlement was beneficial for subsequent land-use. Comparison of prehistoric settlement with contemporary landscape typology also points to a long-term legacy pre-dating historical periods, which makes the landscape our largest and most important heritage monument.

Peripartum echocardiographic changes in women with hypertensive disorders of pregnancy.

Hypertensive disorders of pregnancy (HDP) are associated with significant myocardial dysfunction on echocardiography. The impact of hemodynamic changes related to volume redistribution following delivery on myocardial function in women with HDP has not been evaluated systematically. The aim of this study was to compare echocardiographic findings immediately before and after delivery in women with HDP. This was a prospective longitudinal study including 30 women with a diagnosis of HDP who underwent two consecutive transthoracic echocardiographic (TTE) examinations, before delivery and in the early postpartum period. Paired comparisons of the findings from the two assessments were performed. Left-ventricular (LV) concentric remodeling or hypertrophy was detected in 21 (70%) patients. There was no significant difference in cardiac morphology indices such as LV mass index (78.9 ± 16.3 g/m2 vs 77.9 ± 15.4 g/m2 ; P = 0.611) or relative wall thickness (0.45 ± 0.1 vs 0.44 ± 0.1; P = 0.453) before vs after delivery. LV diastolic function did not demonstrate any peripartum variation, with similar left-atrial volume (52.4 ± 15.3 mL vs 51.0 ± 15.6 mL; P = 0.433), lateral E' (0.12 ± 0.03 m/s vs 0.12 ± 0.03 m/s; P = 0.307) and E/E' ratio (7.9 ± 2.2 vs 7.9 ± 1.7; P = 0.934) before vs after delivery. Systolic function indices, such as LV ejection fraction (57.5 ± 3.4% vs 56.4 ± 2.1%; P = 0.295) and global longitudinal strain (-15.3 ± 2.6% vs-15.1 ± 3.1%; P = 0.582), also remained unchanged between before vs after delivery. Maternal hemodynamic changes associated with delivery did not influence significantly peripartum TTE indices in women with HDP. Suboptimal maternal echocardiographic findings in HDP are likely to be the consequence of chronic pregnancy cardiovascular load changes or pre-existing maternal cardiovascular impairment. Severity and persistence of myocardial dysfunction in the postpartum period may be related to the long-term maternal cardiovascular disease legacy of HDP. © 2021 The Authors.

Palaeoenvironmental proxies indicate long-term development of agro-pastoralist landscapes in Inner Asian mountains

A growing body of archaeological research on agro-pastoralist populations of the Inner Asian mountains indicates that these groups adapted various systems of mobile herding and cultivation to ecotopes across the region from as early as 5000 BP. It has been argued that these adaptations allowed the development of flexible social-ecological systems well suited to the long-term management of these mountain landscapes. At present, less attention has been paid to examining the long-term ecological legacy of these adaptations within the sedimentary or palaeoenvironmental record. Here we present sediment, palynomorph and charcoal data that we interpret as indicating agro-pastoralist environmental perturbations, taken from three cores at middle and high altitudes in the Kashmir Valley at the southern end of the Inner Asian mountains. Our data indicate spatially and temporally discontinuous patterns of agro-pastoralist land use beginning close to 4000 BP. Periods of intensification of upland herding are often coincident with phases of regional social or environmental change, in particular we find the strongest signals for agro-pastoralism in the environmental record contemporary with regionally arid conditions. These patterns support previous arguments that specialised agro-pastoralist ecologies across the region are well placed to respond to past and future climate deteriorations. Our data indicating long-term co-evolution of humans and landscape in the study area also have implications for the ongoing management of environments generally perceived as “pristine” or “wilderness”.

The Brazilian Green Revolution

This article analyzes the critical geopolitics of knowledge production in Brazil during the 20th century. It offers a critical appraisal of recent calls to decolonize political geography by locating the role played by actors and institutions in the Global South within the broader narrative of the Green Revolution. Historical accounts of the Green Revolution have only recently started to incorporate perspectives of and attribute agency to actors in the Global South. However, Brazil has largely been left out of the geographical scope of the Green Revolution. This article focuses on U.S.-Brazilian geopolitical relations behind an effort to reproduce the U.S. model of higher education, rural extension and agricultural research in Brazil. I argue that the confluence of Brazil's geopolitical importance with opportunities for foreign investment in its agricultural sector brought together U.S. and Brazilian experts and expertise to modernize Brazilian agriculture. The case of transnational soybean research illustrates the importance of this relationship in transforming Brazil's agricultural sector and limiting alternatives. This article offers an account of how the geopolitics of knowledge production shape the long-term institutional legacies of national research institutions.

The Debate on Language and Gender in Italy, from the Visibility of Women to Inclusive Language (1980s–2020s)

ABSTRACT This conversation focuses on issues of language and gender and on the debates they have generated in Italy over the past forty years: from linguistic sexism to the role and visibility of women, and then to the representation of non-binary identities. After introducing the differences in expressing gender in Italian and in other European languages, it discusses the proposals made regarding these matters since the 1980s, the reactions to them, and their long-term legacy, mainly in relation to the use of female agentives. The interactions between experts and ‘näive linguists’ are presented as a case study of the popularisation of the debate, and the key role of the digital sphere is also highlighted. Finally, recent suggestions to move beyond the overextended masculine to address mixed-gender groups and non-binary people are analysed (from the asterisk to the schwa), in parallel with similar attempts made in other languages.

Saving the Fundaments: Impact of a Military Coup on the Sudan Health System

Military coups are not uncommon occurrences, particularly in developing nations where political systems might be less firmly entrenched or still evolving. Developments of this nature can often have profound implications for the affected nation’s healthcare systems, both in the immediate aftermath and over the longer term. This paper narrates some notable consequences of political instability on the national health system, particularly placing them in the context of the military coup in October 2021 – emphasizing the context behind the political turbulence, its acute and direct consequences, and the possible long-term legacies of political shocks on the already overwhelmed health system. As a descriptive piece, this narrative does not only look at the impact of the military coup on hospitals, but considers the implications for the healthcare system as defined by the WHO, with particular emphasis on the impact of the coup on health funding from multi-laterals, service delivery, human resource availability, and supply chains in Sudan.

Technospheric Mining of Mine Wastes: A Review of Applications and Challenges

The concept of mining or extracting valuable metals and minerals from technospheric stocks is referred to as technospheric mining. As potential secondary sources of valuable materials, mining these technospheric stocks can offer solutions to minimise the waste for final disposal and augment metals’ or minerals’ supply, and to abate environmental legacies brought by minerals’ extraction. Indeed, waste streams produced by the mining and mineral processing industry can cause long-term negative environmental legacies if not managed properly. There are thus strong incentives/drivers for the mining industry to recover and repurpose mine and mineral wastes since they contain valuable metals and materials that can generate different applications and new products. In this paper, technospheric mining of mine wastes and its application are reviewed, and the challenges that technospheric mining is facing as a newly suggested concept are presented. Unification of standards and policies on mine wastes and tailings as part of governance, along with the importance of research and development, data management, and effective communication between the industry and academia, are identified as necessary to progress technospheric mining to the next level. This review attempts to link technospheric mining to the promotion of environmental sustainability practices in the mining industry by incorporating green technology, sustainable chemistry, and eco-efficiency. We argue that developing environmentally friendly processes and green technology can ensure positive legacies from the mining industry. By presenting specific examples of the mine wastes, we show how the valuable metals or minerals they contain can be recovered using various metallurgical and mineral processing techniques to close the loop on waste in favour of a circular economy.

Family Council From A Cultural Approach: the case of eastern european countries

The family council is a formal mechanism of the family governance in family businesses that aims to give a voice to all members of the family, and to unify the interests of all members. These interests are identified with the purpose of the family, necessary to achieve a long-term legacy, and the sustainability of the company. However, the establishment of the family council is a topic that is still at an incipient stage, both in the literature and for practitioners, so our contribution advances the understanding of family governance within the sphere of family businesses culture and context. For that purpose, we rely on two cultural indexes widely accepted in the literature. We have taken Hofstede’s dimensions and CAGE Distance Framework to explain the establishment of a family council in family businesses settled on the Eastern European countries. The prevailing culture in these countries defines the values and behaviors of their social organizations, namely, the family. The joint study of Hofstede’s dimensions and of the cultural, administrative, and economic differences in the Eastern European countries (CAGE framework) sheds light on how, when and why to establish a family council. This research opens a new field in the intersectional study of culture as an element of sociology and family business in the field of family governance. In advancing this line of research, multilevel analysis through case studies would confirm the coincidence of national values, with individual characteristics.

Woodpeckers and other excavators maintain the diversity of cavity-nesting vertebrates.

Woodpeckers and other excavators create most of the holes used by secondary cavity nesters (SCNs) in North American temperate mixedwood forests, but the degree to which excavators release SCNs from nest-site limitation is debated. Our goal was to quantify how excavators maintain the diversity and abundance of secondary cavity nesters in a temperate forest through the creation of tree cavities. We examined the short- and long-term (legacy) effects of excavators (principally woodpeckers, but also red-breasted nuthatches and black-capped chickadees) on forest biodiversity using longitudinal monitoring data (1,732 nest cavities, 25 sites, 16years) in British Columbia, Canada. Sites with higher densities of excavator nests had more cavities available, higher species richness of SCNs and higher nest density of SCNs, indicating the importance of a standing stock of cavities. Years with higher nesting densities of excavators were followed by years with higher SCN diversity, indicating that the creation of nesting opportunities through fresh excavation releases SCNs from community-wide nest-site limitation. We also show that excavators leave a 'legacy' of biodiversity (species richness and abundance) at a site by accumulating cavities at rates faster than they become unusable by decay or destruction. By quantifying site-level effects of cavity excavation on the SCN community, our study highlights the key role of excavators as ecosystem engineers that maintain forest wildlife biodiversity.

Fire disturbance promotes biodiversity of plants, lichens and birds in the Siberian subarctic tundra.

Fire shapes the world's terrestrial ecosystems and has been influencing biodiversity patterns for millennia. Anthropogenic drivers alter fire regimes. Wildfires can amplify changes in the structure, biodiversity and functioning of the fast-warming tundra ecosystem. However, there is little evidence available, how these fires affect species diversity and community composition of tundra ecosystems over the long term. We studied long-term fire effects on community composition and diversity at different trophic levels of the food web in the subarctic tundra of Western Siberia. In a space-for-time approach we compared three large fire scars (>44, 28 and 12years old) to unburnt controls. We found that diversity (measured as species richness, Shannon index and evenness) of vascular and non-vascular plants and birds was strongly affected by fire, with the greatest species richness of plants and birds for the intermediate-age fire scar (28years). Species composition of plants and birds still differed from that of the control >44years after fire. Increased deciduous shrub cover was related to species richness of all plants in a hump-shaped manner. The proportion of southern (taiga) bird species was highest in the oldest fire scar, which had the highest shrub cover. We conclude that tundra fires have long-term legacies with regard to species diversity and community composition. They may also increase landscape-scale species richness and facilitate range expansions of more southerly distributed species to the subarctic tundra ecosystem.

Do genetically fragmented societies respond less to global warming? Diversity and climate change policies

This research empirically establishes that interpersonal population diversity helps explain worldwide differences in climate change policies. It advances the hypothesis that heterogeneity in the composition of genetic traits, originating from the prehistoric course of the exodus of Homo sapiens from East Africa tens of thousands of years ago, is a major barrier to implementing stringent climate-friendly policies and measures. The underlying intuition is that genetically fragmented societies, characterized by mistrust, preference heterogeneity and persistent poor-quality institutions, find it difficult to sustain collective climate action. Using data for 84 world economies, I find evidence that prehistorically determined genetic diversity has a negative influence on the stringency of climate-related policies and measures. Furthermore, I document that descendants of ancestral societies with greater genetic diversity are less likely to exhibit pro-climate behavior, consistent with a mechanism of inter-generational transmission of cultural norms of mistrust and non-cooperation. The findings suggest that strengthening national responses to changing climate conditions requires considering the long-term legacy of interpersonal population diversity.

The Kindness Group

All students in their senior year in the BSW Undergraduate Program at the University of Southern Maine are required to complete a yearlong field work placement. To support and enhance this process, the students also attend a weekly seminar for the entire academic year. In addition, students are required to complete a Capstone Project. The intent of this Project is that it will have a lasting impact after the student has left their placement. Over the course of the academic year 2017-2018, Kim Lamothe was placed at a Middle School in the Mid Coast region of Maine. For her Capstone Project, Kim came up with the concept of the Kindness Group after reviewing the School’s mission statement, which talked about providing a safe, positive environment for all students whereby respect and appreciation for all differences is the norm. Using her assessment skills and theories that she had covered in her other social work classes, Kim realized that the School could do a better job in realizing these goals. The Kindness Group was an open group. Flyers were distributed throughout the School encouraging students to attend. The Group also used actionable activities, for example, students designed posters and t-shirts. They had a Twin and Triplets Day in which students coordinated outfits. Students were encouraged to listen to their peers and try and imagine what it must be like to walk in their shoes. As part of the long-term legacy activity, the students along with a number of community partners held a yellow tulip project. In the fall semester, they planted hundreds of tulip bulbs. These bulbs all bloomed in the spring and the students dedicated these tulips to those who were suffering from mental illness. Each week in the seminar Kim discussed the Kindness Group. She talked about the successes and frustrations of the Group and all of her peers were extremely supportive. At the end of the academic year, Kim presented her Capstone Project to the class. Everyone was extremely impressed with the work she had undertaken. In addition, Kim and I presented this work at the IASWG 2019 Symposium at NYU. Again, at the Symposium Kim was met with numerous accolades. It was apparent to all that this peer support group had created and cultivated a positive inclusive environment for all.

Changing Work and Work-Related Travel and the Impact of Covid-19

The nature of work was undergoing dramatic change before the pandemic as the digital age continued to transform all sectors of society. In this paper we describe pre-pandemic trends in types of work, the workforce and working arrangements in the UK. We show how these changes were having gradual yet significant impacts on commuting and other work-related travel which were apparent in national travel data series. Key features of these impacts were increasing diversification and flexibility in work travel. We bring together findings on how working practices and travel have been altered by the pandemic and report expectations and opinions on its longer-term legacies. The pandemic has accelerated pre-pandemic trends and led to a shift in how work is performed for almost all sectors of the economy – but grasping the opportunity for this to contribute to deep carbon reductions from transport and to improve equity and health outcomes will require carefully directed policy interventions.

Thatcher’s ‘Right to Buy’ reform at 40: a policy feedback analysis of UK social housing policies

Focusing on policy feedback, this article examines the influence, four decades after its enactment, of Margaret Thatcher’s 1980 ‘Right to Buy’ (RtB) policy on today’s social housing institutions in the UK. We argue that through interest-group feedback mechanisms, RtB helped expand and reinforce the UK landlord class. Furthermore, we assert that the policy pressures placed on local councils to embody housing within the welfare state contributed to a path-dependent, privatisation feedback mechanism. More generally, an analysis of the UK case is important as it could help us think about housing privatisation in terms of policy feedback and long-term historical legacies.

The Coca-Cola Games: Marketing Legacies of the Atlanta Olympic Games

Abstract The 1996 Summer Olympic Games in Atlanta represented a turning point in the commercial orientation of the Olympics. While arguably a commercial success, the Atlanta Games were, and continue to be, heavily criticized for their overly commercial nature. Now, more than twenty years after the Atlanta Games, this article retrospectively examines their long-term marketing legacies. Employing a qualitative case design built from a detailed document analysis using a combination of historical and contemporary sources, this article identifies key marketing and organizational events, circumstances, strategies, and challenges of the Atlanta Games and discusses how they have arguably impacted the future course of Olympic marketing and sponsorship in an effort to expand knowledge and understanding of event management-related legacies.

Predicting climate impacts to the Olympic Games and FIFA Men’s World Cups from 2022 to 2032

In response to concern for climate change impacting sport competitions and legacies, and the need to consider climate adaptability in event planning, this paper uses a combination of historical weather and air quality data as well as the Intergovernmental Panel on Climate Change Fifth Assessment Report to predict climactic conditions for the mega-events of the 2022 through 2032. In doing so, this paper provides a preliminary overview of environmental conditions (e.g. temperatures, air quality, precipitation) that can be used by event planners to inform contingency plans for the events and their legacies. The most immediate concerns for the mega events between 2022 and 2032 include heat conditions unsuitable for competition and poor air quality, but there may be more harmful environmental concerns for the long-term legacies of these events. It is imperative that event organizers consider creating climate-resilient events, infrastructure, and legacies that can withstand environmental threats in the future.

Towards the Use of Land Use Legacies in Landslide Modeling: Current Challenges and Future Perspectives in an Austrian Case Study

Land use/land cover (LULC) changes may alter the risk of landslide occurrence. While LULC has often been considered as a static factor representing present-day LULC, historical LULC dynamics have recently begun to attract more attention. The study objective was to assess the effect of LULC legacies of nearly 200 years on landslide susceptibility models in two Austrian municipalities (Waidhofen an der Ybbs and Paldau). We mapped three cuts of LULC patterns from historical cartographic documents in addition to remote-sensing products. Agricultural archival sources were explored to provide also a predictor on cumulative biomass extraction as an indicator of historical land use intensity. We use historical landslide inventories derived from high-resolution digital terrain models (HRDTM) generated using airborne light detection and ranging (LiDAR), which are reported to have a biased landslide distribution on present-day forested areas and agricultural land. We asked (i) if long-term LULC legacies are important and reliable predictors and (ii) if possible inventory biases may be mitigated by LULC legacies. For the assessment of the LULC legacy effect on landslide occurrences, we used generalized additive models (GAM) within a suitable modeling framework considering various settings of LULC as predictor, and evaluated the effect with well-established diagnostic tools. For both municipalities, we identified a high density of landslides on present-day forested areas, confirming the reported drawbacks. With the use of LULC legacy as an additional predictor, it was not only possible to account for this bias, but also to improve model performances.

Remote Sensing Reveals Lasting Legacies of Land-Use by Small-Scale Foraging Communities in the Southwestern Indian Ocean

Archaeologists interested in the evolution of anthropogenic landscapes have productively adopted Niche Construction Theory (NCT), in order to assess long-term legacies of human-environment interactions. Applications of NCT have especially been used to elucidate co-evolutionary dynamics in agricultural and pastoral systems. Meanwhile, foraging and/or highly mobile small-scale communities, often thought of as less intensive in terms of land-use than agropastoral economies, have received less theoretical and analytical attention from a landscape perspective. Here we address this lacuna by contributing a novel remote sensing approach for investigating legacies of human-environment interaction on landscapes that have a long history of co-evolution with highly mobile foraging communities. Our study is centered on coastal southwest Madagascar, a region inhabited by foraging and fishing communities for close to two millennia. Despite significant environmental changes in southwest Madagascar’s environment following human settlement, including a wave of faunal extinctions, little is known about the scale, pace and nature of anthropogenic landscape modification. Archaeological deposits in this area generally bear ephemeral traces of past human activity and do not exhibit readily visible signatures of intensive land-use and landscape modification (e.g., agricultural modifications, monumental architecture, etc.). In this paper we use high-resolution satellite imagery and vegetative indices to reveal a legacy of human-landscape co-evolution by comparing the characteristics – vegetative productivity and geochemical properties – of archaeological sites to those of locations with no documented archaeological materials. Then, we use a random forest (RF) algorithm and spatial statistics to quantify the extent of archaeological activity and use this analysis to contextualize modern-day human-environment dynamics. Our results demonstrate that coastal foraging communities in southwest Madagascar over the past 1,000 years have extensively altered the landscape. Our study thus expands the temporal and spatial scales at which we can evaluate human-environment dynamics on Madagascar, providing new opportunities to study early periods of the island’s human history when mobile foraging communities were the dominant drivers of landscape change.
