Chronology, time averaging, and oxygen isotope composition of harvested marine mollusk assemblages from Ifri Oudadane, northeast Morocco
Authors: Sanchez William , Yanes Yurena , Linstädter Jörg , Hutterer Rainer 
Published: November 2021

AbstractThe archaeological site of Ifri Oudadane, NE Morocco, contains well-preserved marine mollusk concentrations throughout the Epipaleolithic (hunting-gathering) and Neolithic (food production) cultural phases, useful to test hypotheses driving such transition. However, the chronology and stratigraphy of harvested shells is complex due to the confluence of human activity and natural deposition processes. This work first quantifies the age and degree of time averaging of archaeological shells and then estimates sea-surface temperatures (SSTs) from the oxygen isotopes of selected specimens. Thirty-four radiocarbon-dated shells exhibited significant time averaging between 310 to 1170 yr that could not be explained by analytical error alone. This finding illustrates the need for individually dating shells in future paleoclimate investigations aiming for high temporal resolution. Nine isotopically analyzed shells dated to the Neolithic phase, between 5700 and 7600 cal yr BP, indicate that assuming constant oxygen isotopes of seawater, SSTs remained consistently warm, between 20°C and 22°C, that is, 2°C–4°C warmer than today. Results point to warmer conditions during the Neolithic, supporting the hypothesis that the rise of a food production mode of life in NE Morocco could have in part been triggered by warming conditions following the colder 8.2 event.

AbstractThe Roca San Miguel (RSM) archaeological site was occupied during Mousterian times. Here we present a geoarchaeological and paleoenvironmental reconstruction of the site. Five stratigraphic units (A to E) formed by different archaeological levels are identified. Three optically stimulated luminescence (OSL) ages show that Unit A dates to between 169.6 ± 9.1 and 151.9 ± 11.1 ka, during the penultimate glacial period (PGP), and contains numerous signs of recurring hearths. Unit B is unexcavated. Unit C dates to between 118.9 ± 11.5 and 103.4 ± 6.9 ka (late Eemian–marine isotope stage (MIS) 5d) and shows an abundance of lithic remains as well as some faunal elements. Unit C is covered by Unit D, which incorporates materials moved downslope, and is dated at 81.2 ± 4.7 ka. These OSL ages concur with U/Th ages (129.3 ± 1.5 and 123.6 ± 0.6 ka) derived from a flowstone covered by both -C and D- post-flowstone units. Finally, Unit E covers the archaeological site, which was partially eroded during MIS2. The robust and well-constrained chronology of the RSM site and surroundings enables the establishment of its evolutionary model from the PGP to the last glacial cycle. The RSM site is the oldest Neanderthal occupation accurately dated in the Pre-Pyrenean region.

AbstractOur previous studies have shown that the nutritional properties of peanut meal after fermentation are markedly improved. In this study, in order to facilitate the further utilisation of peanut meal, we investigated the effects of its fermentation extract by Bacillus natto (FE) on cognitive ability, antioxidant activity of brain and protein expression of hippocampus of ageing rats induced by d-galactose. Seventy-two female sd rats aged 4–5 months were randomly divided into six groups: normal control group, ageing model group, FE low-dose group, FE medium-dose group, FE high-dose group and vitamin E positive control group. Morris water maze (MWM) test was performed to evaluate their effects on learning and memory ability in ageing rats. Superoxide dismutase (SOD) activity and malondialdehyde (MDA) content of brain, HE staining and the expression of γ-aminobutyric acid receptor 1 (GABABR1) and N-methyl-d-aspartic acid 2B receptor in the hippocampus of rats were measured. The results show that FE supplementation can effectively alleviate the decrease of thymus index induced by ageing, decrease the escape latency of MWM by 66·06 %, brain MDA by 28·04 %, hippocampus GABABR1 expression by 7·98 % and increase brain SOD by 63·54 % in ageing model rats. This study provides evidence for its anti-ageing effects and is a research basis for potential nutritional benefits of underutilised food by-products.

AbstractThe Eetscore FFQ was developed to score the Dutch Healthy Diet index 2015 (DHD2015-index) representing the Dutch food-based dietary guidelines of 2015. This paper describes the development of the Eetscore FFQ, a short screener assessing diet quality, examines associations between diet quality and participants’ characteristics, and evaluates the relative validity and reproducibility of the Eetscore FFQ in a cross-sectional study with Dutch adults. The study sample consisted of 751 participants, aged 19–91 years, recruited from the EetMeetWeet research panel. The mean DHD2015-index score based on the Eetscore FFQ of the total sample was 111 (sd 17·5) out of a maximum score of 160 points and was significantly higher in women than in men, positively associated with age and education level, and inversely associated with BMI. The Kendall’s tau-b coefficient of the DHD2015-index between the Eetscore FFQ and the full-length FFQ (on average 1·7-month interval, n 565) was 0·51 (95 % CI 0·47, 0·55), indicating an acceptable ranking ability. The intraclass correlation coefficient between DHD2015-index scores derived from two repeated Eetscore FFQ (on average 3·8-month interval, n 343) was 0·91 (95 % CI 0·89, 0·93) suggesting a very good reproducibility. In conclusion, the Eetscore FFQ was considered acceptable in ranking participants according to their diet quality compared with the full-length FFQ and showed good to excellent reproducibility.

AbstractJabuticaba is a Brazilian berry rich in polyphenols, which may exert beneficial effects on metabolic diseases. This randomised crossover study aimed to determine the effects of jabuticaba juice (250 ml in a portion) on postprandial response. Sixteen healthy subjects (eleven women; five men; 28·4 (sd 3·8) years old; BMI 21·7 (sd 2·3) kg/m−2) consumed two test products after fasting overnight in a randomised controlled crossover design. Each test product portion had a similar composition of sugar components: 250 ml water with glucose, fructose, coloured with artificial non-energetic food colourings (placebo), and 250 ml of jabuticaba juice. Beverages were administered immediately before a carbohydrate meal. Blood samples were collected at 0, 15, 30, 45, 60, 90 and 120 min after each test product to analyse the concentrations of glucose, insulin, C-peptide, antioxidant capacity, plasma glucagon-like peptide-1 (GLP-1) and appetite sensations. Compared with the placebo, the intake of jabuticaba juice resulted in a higher GLP-1 response as the AUC and peaking at 60 min. Jabuticaba juice also resulted in higher antioxidant capacity. Postprandial glucose, insulin, C-peptide levels and appetite sensations were not significantly different between tests. In conclusion, 250 ml of jabuticaba juice before a carbohydrate meal was able to improve the antioxidant status and GLP-1 concentrations in healthy subjects.
Family Canon: The Politics of Family during the Last Civic-Military Dictatorship in Argentina, 1976–83
Authors: Juárez-Dappe Patricia 
Published: November 2021

AbstractOn 24 March 1976 a military junta deposed President María Estela Martínez de Perón and assumed power in Argentina. From the first days of the takeover, the authorities worked vigorously to restore what they defined as legitimate Argentine values. This article shows how the family became a focal point of the government's efforts because of its double function as an agent of and a target for renovation. A microcosm of the Argentine nation, the family was considered the basic building block of society, a guarantor of the civic well-being of the nation and, as such, an important ally of the authoritarian state in the fight to restore Argentina's ‘traditional’ values. The analysis focuses on the civic-military regime's efforts to fashion a family canon, which would become the only legitimate version of the Argentine family, and the broad repertoire of strategies used to impose it on the Argentine population.
Plasma scale length and quantum electrodynamics effects on particle acceleration at extreme laser plasmas

In this work, simulations of multipetawatt lasers at irradiances

, striking solid targets and implementing two-dimensional particle-in-cell code was used to study particle acceleration. Preformed plasma at the front surface of a solid target increases both the efficiency of particle acceleration and the reached maximum energy by the accelerated charged particles via nonlinear plasma processes. Here, we have investigated the preformed plasma scale length effects on particle acceleration in the presence and absence of nonlinear quantum electrodynamic (QED) effects, including quantum radiation reaction and multiphoton Breit–Wheeler pair production, which become important at irradiances

${\sim } 10^{23}\ \mathrm {W}\ \mathrm {cm}^{-2}$

. Our results show that QED effects help particles gain higher energies with the presence of preformed plasma. In the results for all cases, preplasma leads to more efficient laser absorption and produces more energetic charged particles, as expected. In the case where QED is included, however, physical mechanisms changed and generated secondary particles (

-rays and positrons) reversing this trend. That is, the hot electrons cool down due to QED effects, while ions gain more energy due to different acceleration methods. It is found that more energetic

-rays and positrons are created with increasing scale length due to high laser conversion efficiency (

Communities of skill in the age of capitalism: Handloom weavers in twentieth-century United Provinces, India
Authors: Rai Santosh Kumar 
Published: November 2021

AbstractThe role of skills has been eclipsed in the transition from an agrarian-craft economy rooted in hand-labour in small households to a modern political economy where productive work takes place outside the household, in offices and factories. Yet the ideological erasure of skilled work should not be confused with its actual disappearance. Precisely because such work was typically construed as private and unimportant, the embedded hierarchies and skills that shaped the handloom weaving industry in the North Indian province of United Provinces under colonial rule could escape systematic conversion to capitalist structures. Skill as human capital constituted the capitalist labour processes in the modern handloom industry, not as an abstract act, but as a historical experience. Handloom workers were reproduced, generationally, socially, and hierarchically, through the passing on of skilled labour within the unorganized informal sector of handloom weaving. Thus the stuff of community skills should move beyond its projection as either ‘endangered’ or ‘regressive’ to explore its access to capitalist structures and the exploitative networks that contain, transmit, and enable the production of skills.
Reform in fragments: Sovereignty, colonialism, and the Sikh tradition
Authors: Judge Rajbir Singh 
Published: November 2021

AbstractThis article rethinks how we understand religious reform under colonial rule by examining Maharaja Duleep Singh, the deposed ruler of the Sikh empire, and how the Singh Sabha, a Sikh reform movement, debated, deployed, and organized around him in the late nineteenth century. I demonstrate how religious reform was a site of intense conflict that reveals the processes of argumentation within the contours of a tradition, even as the colonial state sought to continually mediate the terms. Embedded within a frame of inquiry provided by the Sikh tradition, the contestations that constituted reform within the tradition remained intimately tied in with the question of sovereignty. Ranjit Singh's empire in Panjab had only been annexed 30 years earlier in 1849 and remained a central reference point for thinking about the political at the turn of the century. These debates surrounding Duleep Singh, therefore, disclose the contentious engagements within a tradition that cannot be reduced to binary designations such as colonial construct/indigenous inheritance or religious/political.
A southern Māori perspective on stories of Polynesian polar voyaging
Authors: Anderson Atholl , O’Regan Tipene , Parata-Goodall Puamiria , Stevens Michael , Tau Te Maire 
Published: November 2021

Abstract
As Ngāi Tahu (southern Maori), we take issue with widespread reference in scholarly publication to Polynesian voyagers reaching the Antarctic, an idea that originated in the translation of Rarotongan traditions in the nineteenth century. Analysis of those indicates that they contain no plausible reference to Antarctic seafaring. Southern Māori interests have extended into the Subantarctic Islands for 800 years but there is no reference to Antarctica in our historical traditions. Our archaeology and history document a southern boundary to Māori occupation at Port Ross (Auckland Islands), despite habitable islands existing further south. We think it is very unlikely that Māori or other Polynesian voyaging reached the Antarctic.
Why older rural women in Ireland want to work: it's not all about the money
Authors: Herbert Alison 
Published: November 2021

AbstractThis paper extends our understanding of employment and gendered rural ageing by examining the latent benefits of paid work for mid-life women in rural Ireland. Existing social gerontology literature deals extensively with manifest financial reasons to work, consequences of gendered pay and pension inequalities, work-related health concerns and the negative impacts to an extended working life for women. However, there is much less focus on the latent non-financial positive contributions that work provides for the older woman, especially within a rural context. Findings from this study show how mid-life women, even if in lower-paid, precarious work or in poorer health may choose to continue working into older age. Paid work provides not only financial autonomy, but also temporal structure, life purpose, personal agency, social connectivity and a self-identity that most women are reluctant to relinquish to retirement. Meaningful work plays a critical role in the ageing experience of older rural women. A qualitative study of 25 women aged 45–65 in Connemara, Ireland was undertaken from a lifecourse perspective and analysed using constructivist grounded theory to allow rich, novel narrative to emerge. Narrative from seven, who best represent all participants, are utilised in this paper. Conclusions suggest that the latent benefits of paid work are at least as, if not more important than financial gain for rural mid-life women.
Toward safe and high-performance human–robot collaboration via implementation of redundancy and understanding the effects of admittance term parameters

Published: November 2021

SummaryToday, demandsin industrial manufacturing mandate humans to work with large-scale industrial robots, and this collaboration may result in dangerous conditions for humans. To deal with this situation, this work proposes a novel approach for redundant large-scale industrial robots. In the proposed approach, an admittance controller is designed to regulate the interaction between the end effector of the robot and the human. Additionally, an obstacle avoidance algorithm is implemented in the null space of the robot to prevent any possible unexpected collision between the human and the links of the robot. After safety performance of this approach is verified via simulations and experimental studies, the effect of the parameters of the admittance controller on the performance of collaboration in terms of both accuracy and total human effort is investigated. This investigation is carried out via 8 experiments by the participation of 10 test subjects in which the effect of different admittance controller parameters such as mass and damper are compared. As a result of this investigation, tuning insights for such parameters are revealed.
Variable detectability and El-Niño associations with riparian snakes in Sabah, Malaysian Borneo

Published: November 2021

AbstractAlthough snake populations are suffering numerous local declines, determining the scale of these declines is problematic due to the elusive nature of snakes. Determining the factors associated with species detection is therefore essential for quantifying disturbance effects on populations. From 2017 to 2019, we assessed the detectability associations of five river-associated snake species and all snake detections in general within two logging concessions in Sabah, Malaysian Borneo. Data collected from both stream transects and visual encounter surveys at 47 stream sites were incorporated into an occupancy-modelling framework to determine the climatological, temporal and survey distance associations with species detection probability. Detection probability of riparian snake species was significantly associated with humidity, month (2 spp. each), survey distance and total rainfall over 60 days (1 spp. each). Pooled snake species detectability was significantly positively associated with transect distance and the 2019 El-Niño year, whilst yearly pooled snake species detections in stream transects spiked during El-Niño (2017 = 2.05, 2018 = 2.47, 2019 = 4.5 snakes per km). This study provides new insights into the detectability of riparian rainforest snakes and suggests that future studies should account for short-term (climatological and temporal) and long-term (El-Niño) factors associated with detection probability when surveying and assessing snake populations.
School connectedness as a protective factor against childhood exposure to violence and social deprivation: A longitudinal study of adaptive and maladaptive outcomes

Published: November 2021

AbstractSchool connectedness, a construct indexing supportive school relationships, has been posited to promote resilience to environmental adversity. Consistent with prominent calls in the field, we examined the protective nature of school connectedness against two dimensions of early adversity that index multiple levels of environmental exposure (violence exposure, social deprivation) when predicting both positive and negative outcomes in longitudinal data from 3,246 youth in the Fragile Families and Child Wellbeing Study (48% female, 49% African American). Child and adolescent school connectedness were promotive, even when accounting for the detrimental effects of early adversity. Additionally, childhood school connectedness had aprotective but reactiveassociation with social deprivation, but not violence exposure, when predicting externalizing symptoms and positive function. Specifically, school connectedness was protective against the negative effects of social deprivation, but the effect diminished as social deprivation became more extreme. These results suggest that social relationships at school may compensate for low levels of social support in the home and neighborhood. Our results highlight the important role that the school environment can play for youth who have been exposed to adversity in other areas of their lives and suggest specific groups that may especially benefit from interventions that boost school connectedness.

AbstractBackground:Vascular rings cause respiratory symptoms in children. Treatment consists of surgical division; however, data regarding mid-term results are scarce. The purpose of this study was to evaluate clinical results of vascular ring surgery.Methods:Retrospective chart review of consecutive patients who underwent vascular ring surgery. Mid-term follow-up consisted of clinic visits and telephone questionnaire over a 1-year period sampling at five points in time.Results:Follow-up of 85 patients who underwent vascular rings surgery revealed significant symptomatic improvement within 6 months. In total, 50% were symptomatic to some degree at their last documented clinic visit complaining of stridor (36.8%), cough (34.2%), wheezing (10.5%), dyspnoea on exertion (10.5%), or recurrent respiratory infections (23.7%). By telephone questionnaires, 83% described a significant improvement in respiratory symptoms, 63.4% had some residual symptoms, 36.6% stridor, 38.8% chronic cough, 32.4% bronchodilator use,18.3% had at least one episode of pneumonia per year, 31% of children had dyspnoea or respiratory limitation, and 12.7% while doing physical activities. We found no association between the age at surgery or anatomic variant to the presence of symptoms at mid-term follow-up.Conclusions:Surgical division of vascular rings results in significant clinical improvement within 1 year; nevertheless, some patients remain symptomatic to some degree. We found no association between the age at surgery or anatomic variant to the presence of symptoms at mid-term follow-up. Further evaluation is warranted to assess the nature of residual symptoms and explore whether anatomical causes can be identified leading to surgical modifications.
