Ancestry and kinship in a Late Antiquity-Early Middle Ages cemetery in the Eastern Italian Alps

In South Tyrol (Eastern Italian Alps), during Late Antiquity-Early Middle Ages, archeological records indicate cultural hybridization among alpine groups and peoples of various origin. Using paleogenomics, we reconstructed the ancestry of 20 individuals (4th-7th cent. AD) from a cemetery to analyze whether they had heterogeneous or homogeneous ancestry and to study their social organization. The results revealed a primary genetic ancestry from southern Europe and additional ancestries from south-western, western, and northern Europe, suggesting that cultural hybridization was accompanied by complex genetic admixture. Kinship analyses found no genetic relatedness between the only two individuals buried with grave goods. Instead, a father-son pair was discovered in one multiple grave, together with unrelated individuals and one possible non-local female. These genetic findings indicate the presence of a high social status familia, which is supported by the cultural materials and the proximity of the grave to the most sacred area of the church.

Where do successful populations originate from?

In order to understand the dynamics of emergence and spreading of socio-technical innovations and population moves it is important to determine the place of origin of these populations. Here we focus on the role of geographical factors, such as land fertility and mountains in the context of human population evolution and distribution dynamics. We use a constrained diffusion-based computational model, computer simulations and the analysis of geographical and land-quality data. Our analysis shows that successful human populations, i.e. those which become dominant in their socio - geographical environment, originate from lands of many valleys with relatively low land fertility, which are close to areas of high land fertility. Many of the homelands predicted by our analysis match the assumed homelands of known successful populations (e.g. Bantus, Turkic, Maya). We also predict other likely homelands as well, where further archaeological, linguistic or genetic exploration may confirm the place of origin for populations with no currently identified urheimat. Our work is significant because it advances the understanding of human population dynamics by guiding the identification of the origin locations of successful populations.

Naive geography: geoconceptology and topology of geomental maps

The article presents the study of the geospace mental representations and their variability depending on the regional point of view. The research material comprises about 500 naive maps of Russia, created by informants of seven Russian regions: Moscow, St. Petersburg (capitals), Siberia (Barnaul, Biysk), Southern, Mid- and Northern Ural (Orenburg, Ufa, Perm) and Kaliningrad. A geoconcept, as a set of collective ideas about a geographic object, synthesizes images of a geographic location (topos), its name (toponym), ideas about it and its spatial parameters (length, coordinates, location relative to other geolocations). The paper raises the problem of the topology of the mental space, and describes the method and results of constructing computable metric models of geomental spaces. The use of modern means of processing and analyzing naive maps allowed to detect spatial dependencies between geoconcepts, their probable localization zones, and position relative to each other on the geomental map space. Modeling of geoconcepts was carried out on the example of the analysis of the collective regional representations associated with the capital (Moscow). Noticeable differences were found in the regional geoconcepts of Moscow, which makes it relevant to conduct research on the regional variability of the geoconcept systems of the country's common space.

Indigenous knowledge in relation to climate change: adaptation practices used by the Xo Dang people of central Vietnam

Even though indigenous knowledge (IK) is considered as one of the most effective strategies in response to climate change issues, this form is not being sufficiently integrated into the climate change planning and policy at both local and national levels in Vietnam. This study investigates the role of the traditional agricultural practices of the Xo Dang ethnic minority groups in Central Vietnam and provides insights into the factors that influence farmers to adopt these practices in response to climate change. Primary data was obtained through three focus group discussions and 87 household surveys involving the Xo Dang people through face-to-face semi-structured interviews in the Tra Doc commune, Bac Tra My district, Quang Nam province, Central Vietnam. The binary logistic regression model was used to examine the factors which have influenced the choices made by this community in response to climate change. The results showed that Xo Dang people were highly aware of climate change risks and had, in response, employed their current adaptation practices. The major adaptation strategies implemented by the Xo Dang people included the use of flora and fauna indicators, native plant varieties, the adjustment of planting calendars, irrigation practices, and the application of intercropping. The results indicated that the living years, their monthly farm incomes, and farmer's perceptions of ongoing climate change effects on their environment were the factors that significantly affected farmers' adaptation decisions. Understanding indigenous knowledge plays a fundamental role in the processes of deciding the appropriate adaptation techniques more effectively and making use of human resources. Therefore, policy makers should pay much attention to indigenous knowledge to combat climate change in future national policies and projects.

Correlates of access to hand hygiene resources in Ghanaian households: An exploratory analysis of the 2014 demographic and health survey

Objectives

Handwashing with soap and water remains the most effective public health measure to reduce the risk of infectious diseases, which kill over 2.5 million people annually, mostly children in developing countries. The absence of hand hygiene resources in homes put many at risk of these infectious diseases. In the wake of the outbreak of the COVID-19 pandemic, the World Health Organization (WHO) and governments around the world have stressed the importance of regular handwashing to prevent the spread of the virus. This suggests that research on water, sanitation, and hygiene issues deserve continuous scholarly attention. In Ghana, studies on household's access to hand hygiene resources are few and relatively old. Therefore, this study estimated the proportion of Ghanaian households with access to hand hygiene resources and their associated determinants using data from a recent national survey.

Methods

The study used the cross-sectional 2014 Ghana Demographic and Health Surveys dataset. We used STATA-14 to perform data analyses on a weighted sample of 11,710.06 households. We used complex samples analysis technique to adjust for sample units, stratification and sample weights for both the descriptive statistics and multivariate robust Poisson regression.

Results

The result showed that about one fifth of Ghanaian households had access to hand hygiene resources. Households with heads who attained a Middle/JHS/JSS or Secondary/SSS/SHS/Higher level education, those headed by persons having at least 30-44 years, and non-poorest households, and from the Volta region were more likely to have access to hand hygiene resources. Further, households in urban areas, households that spent between 0-30 min to get to a source of water, and households in Eastern and Brong-Ahafo regions were less likely to have access to hand hygiene resources.

Conclusion

This study identified key socioeconomic and demographic correlates of a household's access to hand hygiene resources in Ghana. In the interim, the government and development partners can provide hand hygiene resources to households with limited or no access. For the long term, we recommend that the government should implement measures and policies that facilitate citizens' economic independence and their attainment of higher formal education.

The Female Empowerment Index (FEMI): spatial and temporal variation in women's empowerment in Nigeria

Improving female empowerment is an important human rights and development goal that needs better monitoring. A number of indices have been developed to track female empowerment at the national level, but these are incomplete and may obscure important sub-national variation. We developed the Female Empowerment Index (FEMI) to track multiple domains of women's empowerment at the sub-national level. The index is based on six categories of empowerment: violence against women, employment, education, reproductive healthcare, decision making, and access to contraceptives. The FEMI has a range of zero to one (low to high empowerment), and it is calculated as the mean proportion of positive outcomes in the six categories. To provide a proof of concept, we computed the FEMI for Nigeria and its 36 states from five Demographic and Health Surveys between the years of 1990 and 2013, using questions asked to 98,542 women between 15 and 49 years old. At the national level, the FEMI increased from 0.34 to 0.48. However, there was substantial sub-national variation, with state-level values ranging from 0.16-0.60 in 1990 to 0.19–0.73 in 2013. Our findings thus illustrate the importance of considering sub-national variation in female empowerment. The FEMI can be readily computed for other countries, and its ability to track spatial and temporal variation in woman's empowerment across a broad set of categories may make it more useful than existing approaches.

Effect of REDD+ projects on local livelihood assets in Keo Seima and Oddar Meanchey, Cambodia

Climate-change mitigation projects are expected to improve local livelihoods in targeted areas. Several REDD+ projects aimed at reducing emissions from deforestation and forest degradation, conserving and enhancing forest carbon stocks, and sustainably managing forests have been implemented in Cambodia but few studies have examined the effects on local livelihoods before and during project implementation. Our study applies a sustainable livelihood framework to assess the livelihood assets of local communities in the Oddar Meanchey and Keo Seima REDD+ project sites in Cambodia before and during project implementation. Five capital assets, namely natural, physical, human, financial, and social capital, are assessed and scored on a 1-to-5 Likert scale. Data analysis collected through 252 interviews in Oddar Meanchey and Keo Seima reveals a slight increase in livelihood assets in both sites from project validation to implementation. Generally, the mean scores for local livelihood assets increased from 2.81 ± 0.07 (±is followed by the standard error) and 2.66 ± 0.06 to 3.07 ± 0.09 and 3.06 ± 0.08 in Oddar Meanchey and Keo Seima, respectively. Nevertheless, natural capital assets sharply declined from 3.50 and 3.32 to 2.09 and 2.25, respectively. Respondents mainly blamed illegal logging for the decline, suggesting that strict patrolling and enforcement must be implemented. Furthermore, the scarcity of carbon-credit buyers and the projects’ inability to generate carbon-based revenues has led to dissatisfaction among local communities, inducing avoidable illegal activities in pursuit of short-term benefits. A financial mechanism to ensure sufficient and sustained financial support regardless of carbon-market volatility is urgently needed.

Arctic design: revisiting traditional fur clothing within the daily routine of reindeer nomads

This research investigates the domain of indigenous fur clothing for the extreme conditions of the Arctic. The main goal is to reveal the principles of personal wellbeing through observing and analyzing traditional Nenets fur coat and footwear together with the actual experiences of making and using clothing items. For that, we draw from the existing pool of research on functional parameters tested and evaluated in a lab and our empirical data (interviews and participant observations 2013–2016), to eventually come up with two interwoven concepts of clothing based on bio- and cultural mimesis. On the one hand, traditional fur clothing is the result of the biomimetic appropriation of natural abilities of reindeer to withstand severe climates. On the other, it is the embodiment of knowledge on the environment and skills acquired through the dynamic relationship between tools, materials, and personal identities of makers and wearers. This conceptualization, we argue, provides insights into how to both support the very existence in the extreme/severe environment and contribute to personal wellbeing. We conclude by proposing directions for further research towards developing design standards for the emerging multicultural community of Arctic newcomers.

Evaluating the conservation state of the páramo ecosystem: An object-based image analysis and CART algorithm approach for central Ecuador

Ecuadorian páramo ecosystems (EPEs) function as water sources, contain large soil carbon stores and high levels of biodiversity, and support human populations. The EPEs are mainly herbaceous páramo (HP). To inform policy and management and help drive ecological science toward a better understanding of the HP ecosystem, and the relationships among its multiple ecosystem services, we asked: (1) What is the state of the HP regarding its land use/land cover (LULC)?; and (2) Is the HP being pushed away from its natural state or it is regenerating? To answer these questions, we assessed the LULC in central EPEs using Landsat 8 imagery, Object-Based Image Analysis (OBIA) and a Classification and Regression Trees (CART) algorithm. Results show that two-fifths of the paramo ecosystem remain as native HP (NHP) and two-fifths as anthropogenic HP (AHP). Although the anthropic alteration of the pedogenesis of young paramo soil leads to the establishment of AHP, we found evidence of regeneration and resilience of the NHP. The results of this study will be useful to scientists and decision-makers with interest in páramo ecosystems in central Ecuador. The proposed methodology is simple, fast, and could be implemented in other landscapes to establish comprehensive monitoring systems useful in landscape assessment and planning.

New Jersey's waste management data: retrospect and prospect

Reliable data about collection, volume, tonnage, stream composition, and disposal price have long been described as key components of successful solid waste management planning. Yet, concerns about data quality and quantity have continued to limit even the most sincere, progressive waste management schemes. This paper examines solid waste management data that has been collected in the US state of New Jersey starting in the 1960s. We present the origins of waste management data collection in New Jersey and trace some of the applications that have been made with the data over time. We compare the New Jersey dataset to waste management data that has been collected in other US states. We then describe our work collecting, cleaning, and preparing for public dissemination and use in a geospatial visualization exercise a digital version of the data spanning approximately 1993 to 2016, before presenting some illustrations of the type of modeling and analysis that researchers or the concerned public would be able to undertake now that the dataset is available. (We are publishing the 1993–2016 dataset alongside this paper). We argue that the New Jersey waste management dataset is much better than most other waste datasets in the US, but despite this fairly high quality, there remain significant gaps which inhibit the ability of planners to design and implement comprehensive waste management plans. That there are limits inherent to the New Jersey dataset suggests, we argue, a ceiling to the usefulness of waste management data as a category of environmental knowledge with possible implications for ‘big’ environmental data more broadly.

Cacogenic Cartographies: Space and Place in the Eugenic Family Study

Though only one component product of the larger eugenics movement, the eugenic family study proved to be, by far, its most potent ideological tool. The Kallikak Family, for instance, went through eight editions between 1913 and 1931. This essay argues that the current scholarship has missed important ways that the architects of the eugenic family studies theorized and described the subjects of their investigation. Using one sparsely interrogated work (sociologist Frank Wilson Blackmar's "The Smoky Pilgrims") and one previously unknown eugenic family study (biologist Frank Gary Brooks' untitled analysis of the flood-zone Oklahomans) from the Southern Plains, this essay aims to introduce "environment" as a schema that allows for how the subjects of the eugenic family study were conceptualized with respect to their surroundings. Geospatially and environmentally relevant constructions of scientific knowledge were central to the project of eugenics during its formative years, but remain largely and conspicuously absent from the critical literature which engages this project to separate the fit from the unfit in American society. The dysgenic constituted a unique human geography, giving us significant insight into how concatenations of jurisprudence as well as cultural and social worth were tied to the land.
