Gender perspective on the social networks of household heads and community leaders after involuntary resettlement

The study of social network analysis in Indonesia and the Philippines reveals that after a certain period in a new community and living among involuntarily resettled strangers, household heads and community leaders will eventually replace their disrupted previous networks with new network ties. The paper likewise demonstrates how gender moulds social network features at the levels of the Indonesian household heads and Philippine community organization after involuntary resettlement. Existing gendered context in two settings like the Indonesian woman’s role as primary caretaker of the household and the absence of a consolidated patriarchal system in the Philippines is shown to have reinforced gender (dis)advantages. As reflected in the two settings, those who have the biggest networks are also the brokers or the influential actors who can control and have an advantage in accessing social capital. Further, basing on the two cases, we identify the gender norm of the centrality of women’s role as homemaker and caregiver in addition to other roles as a similar explanation for the bigger proportions of friends in the networks of women as compared to men. Unless outside interventions reconfigure the natural trajectory of the social networks, gender equality in terms of leadership, decision-making and access to suitable programs and projects as well as to the relevant authorities, remains problematic.     

Agglomeration economies and the location of foreign direct investment: A meta‐analysis

This paper undertakes a meta‐analysis of the effect of agglomeration economies on foreign direct investment (FDI) location. It finds strong differences in these economies arising from both measurement and study‐specific characteristics. Economies generated from domestic rather than foreign activity have the strongest effects on FDI, with the latter only significant if related to the home country of the investor. Support is also found for studies that identify different sources of agglomeration economies, although this is largely underexplored in the empirical literature. The average agglomeration economies estimate is not influenced by publication bias and indicates genuine effects for agglomeration economies on FDI location choice.     

Australia’s anti-Islam right in their own words. Text as data analysis of social media content

In recent years, far-right organisations have formed in response to what they believe to be the threat from the rise of Islam in Australia. Parallel movements have spawned an extensive literature internationally. In this study I investigate this movement in Australia using automated text analysis of all public posts from two of the most popular Australian anti-Islam groups on social media. This approach complements traditional polling methods by offering access to large samples of the spontaneously generated opinions, allowing subjects to speak in their own words. My analysis finds evidence that concerns about terrorism and the perceived political threat from Islam are paramount in these groups’ discussion of Muslims. I conclude by discussing the implications for counter-messaging strategies.     

Reconstruction of Socioeconomic Status in the Medieval (14th–15th Century) Population of Grevenmacher (Luxembourg) Based on Growth,Development and Diet

Numerous historical sources describe many aspects of the estate‐based society in medieval times; the detection of socioeconomic status within populations through skeletal remains is a topic of growing interest in anthropological studies. In medieval times, it was common for members of high social rank to be buried within or next to a church. This was certainly the case in Grevenmacher (Luxembourg), where remains of a church building and an adjacent cemetery from the 13th until the beginning of the 15th century were subjected to archaeological and anthropological analysis. By integrating archaeological and anthropological elements, as well as stable isotope analysis, we documented osteological manifestations as indicators of diet differentials in two subsamples (first group consists out of 56 individuals, second one out of 184 individuals) from the medieval cemetery of Grevenmacher. We could distinguish two subsamples that we assumed as different in their socioeconomic status with regards to the burials' position in the cemetery and burial characteristics. Differences in osteological traits such as bone length, stature and body mass indicated differences in diet between sample groups. To substantiate these outcomes, stable isotopic analysis (δ¹³C, δ¹⁵N) were made; the results displayed a clear separation between the sample groups on the basis of their diet. Therefore, we were able to confirm certain individuals in the medieval population of Grevenmacher in relationship to their socioeconomic status. Copyright © 2017 John Wiley & Sons, Ltd.     

Wood exploitation and food supply at the border of the Roman Empire: the case of the vicus of Thamusida – Sidi Ali ben Ahmed (Morocco)

This paper presents the results of inter-disciplinary work drawing on archaeobotanical and archaeometric studies to trace the agroforestry landscape and the supply economy at the vicus of Thamusida in north-west Morocco at the border of the Roman Empire. The available data indicate the self-sufficiency of the settlement in both forestry and agricultural products throughout the period investigated from the end of the 1st century BC to the beginning of the 4th century AD. Charcoal data testify to the presence of a Quercus suber forest in the close surroundings of the site and its exploitation for a variety of forestry products such as timber, fuelwood, cork, and probably also leaves and acorns to feed livestock. The overwhelming presence of Q. suber in the archaeological layer investigated clearly indicates that this forest was under human influence prior to Roman occupation and was already partially degraded. Charred seed and fruit remains suggest that the diet of both troops and civilians was mainly based on locally grown products and that all the inhabitants of the site had access to good cereals such as barley, naked wheats and pulses with large seeds such as horse bean and pea; quality fruits, such as olive and grape, were also produced locally for fresh consumption. Organic residue analyses of the contents of ceramic vessels and plastered vats allowed archaeobotanical data to be complemented, thereby shedding light on some of the imports at Thamusida. Despite the remote location of this settlement, imported goods such as oil and wine were transported here in amphorae from different parts of the Empire.     

Chemical Residues as Anthropic Activity Markers. Ethnoarchaeology,Experimental Archaeology and Archaeology of Food Production and Consumption

ABSTRACT

Chemical residues preserved in floors can be considered anthropic activity markers. In fact, residues are strictly related to the activities performed and reflect their spatial distribution. We present a synthesis of the work carried out over the last few decades in Mexico and Italy related to the study of chemical residues in floors. Residues can be identified performing specific chemical analyses both of plastered or earthen floors samples. We outline a methodological approach concerning the use of the markers of the activities to interpret food production and consumption in the archaeological record, based upon evidence from experimental, ethnoarchaeological and archaeological examples. Here we point out the advantages and problems of such an approach, mainly related to equifinality, of the use of spot tests and gas chromatography coupled with mass spectrometry techniques using examples from different sites in the world.     

Connecting to food: cultivating children in the school garden

School gardens are widely celebrated as spaces to promote health and sustainability by connecting children with their food. While scholars have assessed the effects of gardening in practice, media discourses play a key role in constituting this site. This paper examines how the school garden is discursively constituted within American and Canadian newspaper coverage. The analysis reveals specific forms of connection that are said to flourish in the school garden: between food production and consumption, between bodies and knowledge, and between the urban child and nature. While all children are said to benefit from connecting with their food, these connections are articulated differently in relation to particular bodies and spaces, evident in racialized and classed narratives of stewardship and salvation. As children’s relationship to food is invested with the hopes and fears of collective futures, the discursive construction of the school garden provides crucial insights into contemporary understandings of childhood.     

Methods and Challenges for the Seismic Assessment of Historic Masonry Structures

ABSTRACT

Despite the high vulnerability of historic structures to earthquakes, the approaches for evaluating seismic demand and capacity still appear inadequate and there is little consensus on the most appropriate assessment methods to use. To develop an improved knowledge on the seismic behavior of masonry structures and the reliability of analysis tools, two real-scale specimens were tested on a shake table, and several experts were invited to foresee failure mechanism and seismic capacity within a blind prediction test. Once unveiled, experimental results were simulated using multi-block dynamics, finite elements, or discrete elements. This article gathers the lessons learned and identifies issues requiring further attention. A combination of engineering judgment and numerical models may help to identify the collapse mechanism, which is as essential as it is challenging for the seismic assessment. To this purpose, discrete modeling approaches may lead to more reliable results than continuous ones. Even when the correct mechanism is identified, estimating the seismic capacity remains difficult, due to the complexity and randomness of the seismic response, and to the sensitivity of numerical tools to input variables. Simplified approaches based on rigid body dynamics, despite the considerable experience and engineering judgment required, provide as good results as do advanced simulations.     

Frequencies of Rare Incisor Variations Reflect Factors Influencing Precontact Population Relationships in Mexico and the American Southwest

Mexican prehistory is characterized by migration and population isolation in its earliest phase, followed by later inter‐population cultural interactions, such as politics and trade. While shared, common morphological variants are often informative about recent population events, rare trait variants have not been widely investigated to see whether they might be informative about earlier events. Here, we consider populations that show several rare variants at frequencies high enough to warrant such an investigation. Examining past population structure can help us understand population interactions across different periods of time, levels of migration, and population isolation/drift. Multiple‐origin populations may have more variation, including more and higher rates of rare traits. We examined maxillary lateral incisors in 1117 dentitions from 76 samples of Preclassic/Classic and Postclassic pre‐European contact Mexico and the American Southwest for the prevalence of rare lateral incisor variants. Variants observed included barrel, congenital absence, interruption groove, mesial marginal bending, peg, reduced, supernumerary, and talon teeth. The most common variant overall is interruption groove. Central Mexico, Huasteca, and the Lowland Yucatan region samples present the highest overall number of incisor variants. Higher frequencies of single unusual traits are commonly found in samples from smaller populations, while samples from larger population centres show a greater range of these rare variants. We investigated to see whether the pattern of rare incisor variant frequencies reflected early or later population history by comparing similarity/distance matrices and factor model matrices using Mantel tests and Generalized Procrustes analysis. Results show a weak relationship with the Postclassic period and shared migration/language and trade interaction models. We suggest that later cultural interactions have acted to mask earlier population history. Research on serial founder effects should be approached multiregionally and across time, to avoid missing inter‐region biological relationships. Copyright © 2015 John Wiley & Sons, Ltd.
