Intergroup Contact and Negative Attitudes Towards Immigrants Among Youth in Sweden: Individual and Contextual Factors
Authors: Bentsen Beint Magnus Aamodt 
Published: May 2021

AbstractNegative attitudes towards out-groups have been of academic interest for many years — and even more so with the increased levels of migration to European countries in recent years. Building on insights from intergroup contact theory, this paper seeks to extend our knowledge of the association between contact and negative attitudes toward immigrants among youth in Sweden. Multiple regression analysis and fixed effects models are used to analyze a large, high-quality dataset on Swedish adolescents based on representative survey information, complemented with extensive registry data and official statistics. Our objective is to measure contact on different levels in order to better understand the importance of these different contact variables’ associations with negative attitudes. The results of the analysis indicate that high-quality contact in the form of friendship is associated with a reduction in negative attitudes among Swedish adolescents, even after controlling for background variables. Superficial forms of contact — measured on the school level — are, on the other hand, associated with an increase in negative attitudes.

AbstractStudents’ poor well-being is a serious problem in higher education. In part, this problem is related to the problems in studying as poorer study skills are related to poorer well-being. Both students’ study skills and their well-being should be enhanced in higher education, but effective ways to do this are needed. The aim of this study was to explore students’ experiences of an ACT-based online, 8-week course on university students’ well-being and studying. Data were collected in two ways: a) with qualitative data consisting of learning journals (n = 97) and with b) a pre- and post-questionnaire (n = 143) during the course. The students’ scores on well-being, psychological flexibility, and time and effort management skills improved, and stress levels decreased during the course. Qualitative analyses showed that the students benefited from the course in many ways, both in terms of studying and well-being; their studying and time management skills had improved and they had learnt stress management skills and how to cope with their negative thoughts. We argue that supporting students’ well-being, as well as their study skills with ACT-based course in higher education studies, can lead to more effective studying.

Inca human sacrifices from the Ampato and Pichu Pichu volcanoes, Peru: new results from a bio-anthropological analysis
Authors: Socha Dagmara M. , Reinhard Johan , Perea Ruddy Chávez 
Published: May 2021

AbstractOne of the most important rituals in the Inca Empire was thecapacocha. It required the most prestigious sacrificial offering of male and female children and young women who were characterized by their beauty and purity. The aim of this paper is to present the results of a bio-anthropological analysis of the remains of five individuals sacrificed on the summits of Ampato and Pichu Pichu during this ritual. Various methods (bone analysis and radiography) were applied in the investigation due to the diverse states of preservation of the remains. Four individuals were in the same age category: 6–7 years old. The individual Pichu Pichu #2 was sacrificed at age 3.5 years, which makes him the youngestcapacochasacrifice currently known. Results show proper development of the victims’ bodies, the presence of stress markers related to the early childhood period, and, in the case of the Ampato boy, malformation of the cervical vertebrae. The studies of the Pichu Pichu and Ampato sacrifices confirm their widespread origins, privileged position, and high social status. They show that the victims were well-nourished and had proper body growth compared to juveniles from the lower social strata in different cemeteries in the region.
Four Responsibility Gaps with Artificial Intelligence: Why they Matter and How to Address them
Authors: Santoni de Sio Filippo , Mecacci Giulio 
Published: May 2021

AbstractThe notion of “responsibility gap” with artificial intelligence (AI) was originally introduced in the philosophical debate to indicate the concern that “learning automata” may make more difficult or impossible to attribute moral culpability to persons for untoward events. Building on literature in moral and legal philosophy, and ethics of technology, the paper proposes a broader and more comprehensive analysis of the responsibility gap. The responsibility gap, it is argued, is not one problem but a set of at least four interconnected problems – gaps in culpability, moral and public accountability, active responsibility—caused by different sources, some technical, other organisational, legal, ethical, and societal. Responsibility gaps may also happen with non-learning systems. The paper clarifies which aspect of AI may cause which gap in which form of responsibility, and why each of these gaps matter. It proposes a critical review of partial and non-satisfactory attempts to address the responsibility gap: those which present it as a new and intractable problem (“fatalism”), those which dismiss it as a false problem (“deflationism”), and those which reduce it to only one of its dimensions or sources and/or present it as a problem that can be solved by simply introducing new technical and/or legal tools (“solutionism”). The paper also outlines a more comprehensive approach to address the responsibility gaps with AI in their entirety, based on the idea of designing socio-technical systems for “meaningful human control", that is systems aligned with the relevant human reasons and capacities.
Stakeholder engagement vs. social distancing—how does the Covid-19 pandemic affect participatory research in EU marine science projects?

Published: May 2021

AbstractIn the realm of marine science, engaging with stakeholders (e.g., industry members, policy-makers, managers, NGOs) is an important method applied in many research projects. The Covid-19 pandemic has severely impacted this engagement in two ways. First, social distancing measures forbid most face-to-face participatory activities originally envisioned in projects. Second, the restrictions have caused hardships for the stakeholders being engaged by these projects. We assessed the impact of Covid-19 on stakeholder engagement activities in ongoing EU marine science projects by posing the following questions: What problems has Covid-19 caused for the workflow and outcomes of current research projects, (ii) how have scientists responsible for stakeholder engagement coped with the situation, and (iii) if alternative stakeholder activities were implemented, how have these been evaluated? Our survey was conducted nearly 2 months after the onset of Covid-19 lockdowns. It addressed researchers who engage with stakeholders in EU projects and delivers insights into the practical implications of Covid-19 for stakeholder engagement and the measures taken to tackle this challenge. The paper highlights the impacts of the pandemic on stakeholder engagement in marine science, outlines current coping strategies in different EU projects, and recommends seven practical actions to promote and maintain meaningful exchange with stakeholders in times of social distancing and lockdowns.

AbstractThe most commonly used construction material nowadays is steel-reinforced concrete which underlies corrosion and thus buildings are susceptible for structural collapses. Recently, a new construction material resistant to oxidation and with a higher tensile strength called carbon concrete composite (C3) was developed. The new material allows resource-saving constructions using carbon fiber instead of steel reinforcement materials embedded in a concrete matrix. C3 reinforcements consist of carbon fibers coated with an organic polymer matrix. In this study, abrasive dust from a dry cutting process of two C3 reinforcement materials, as well as a C3 material were investigated with respect to the occurrence of toxic fibers or harmful organic compounds in the inhalable particulate matter (PM) fractions PM2.5 and PM10. It could be shown that the ratio between elemental and organic carbon in PM10 is dependent on the shape of the C3 reinforcement material due to different mechanisms of PM formation. This could have an impact on the toxicity of different C3 reinforcement materials. Harmful fibers according to the World Health Organization (WHO) definition like they are found in asbestos concrete were not found. However, bisphenol A (BPA) as well as the PAHs phenanthrene, anthracene, fluoranthene and pyrene were found due to pyrolysis of the organic matrix material at the edge of the sawblade differentiating the Carcinogenic Equivalency (TEQ) of investigated materials and their PM fractions. Furthermore, derivatives of BPA occurred in abrasive dust from C3 reinforcement materials potentially leading to genotoxicity and reproductive toxicity.
A dislocation density-based model for the work hardening and softening behaviors upon stress reversal
Authors: Lisiecka-Graca Paulina , Bzowski Krzysztof , Majta Janusz , Muszka Krzysztof 
Published: May 2021

Abstract
The mechanical behaviours of microalloyed and low-carbon steels under strain reversal were modelled based on the average dislocation density taking into account its allocation between the cell walls and cell interiors. The proposed model reflects the effects of the dislocations displacement, generation of new dislocations and their annihilation during the metal-forming processes. The back stress is assumed as one of the internal variables. The value of the initial dislocation density was calculated using two different computational methods, i.e. the first one based on the dislocation density tensor and the second one based on the strain gradient model. The proposed methods of calculating the dislocation density were subjected to a comparative analysis. For the microstructural analysis, the high-resolution electron backscatter diffraction (EBSD) microscopy was utilized. The calculation results were compared with the results of forward/reverse torsion tests. As a result, good effectiveness of the applied computational methodology was demonstrated. Finally, the analysis of dislocation distributions as an effect of the strain path change was performed.
Adaptive sliding mode formation control for multiple flight vehicles with considering autopilot dynamic
Authors: Li W. , Wen Q. , Zhou H. 
Published: May 2021

ABSTRACT
This paper mainly focuses on the cooperative control of formation configuration for multiple flight vehicles in the three-dimensional space. Considering the external disturbance of the system, the adaptive non-singular terminal sliding mode control law (NTSMC) is designed based on the virtual leader-follower method, which aims to ensure that each flight vehicle reaches the expected terminal position in a limited time and meet the configuration constraints. Further considering the first-order dynamic characteristic of the autopilot, a novel second-order sliding mode control (SOSMC) law is deduced with using the estimated information of sliding mode disturbance observer. The proposed control method ensures that all flight vehicles form the required space formation configuration simultaneously at a pre-designed time, and the chattering phenomenon of the sliding mode surface and acceleration response that nears the equilibrium point is effectively weaken. The stability of the proposed control law is verified by theoretical analysis and lots of mathematical simulations. The results show that the control algorithm in this paper can be used to guidance the formation controller design of multiple flight vehicles in the mid-guidance phase to some extent, and thus the cooperative flight stability of the system can be effectively improved.
Joint adoption of rice technologies among Bolivian farmers

Published: May 2021

Abstract
Bolivia has disseminated several improved technologies in the rice sector, but the average rice productivity in the country is far below the average trend in Latin America in recent years. Although the economic literature has highlighted the role of agricultural technology adoption in increasing agricultural productivity, gaps remain in understanding how rice growers are deciding to adopt and benefit from available improved rice technologies. Most previous adoption studies have evaluated the uptake of individual technologies without paying attention to the complementarities that alternative improved rice technologies may offer to farmers who face multiple marketing and production needs. This study uses data from a nationally representative sample of Bolivian rice growers to analyze farmers' joint decisions in adopting complementary agricultural technologies controlling for potential correlations across these decisions, as well as the extent of adoption of these practices. Evidence suggests that the decisions on multiple technology adoption are closely related, with common factors affecting both adoption and the extent of adoption. Furthermore, there is a need to better target resource-poor farmers, improve information-diffusion channels on agricultural practices, and better use existing farmers' organizations to enhance rice technology adoption.

Abstract

Introduction:
Interdisciplinary academic teams perform better when competent in teamwork; however, there is a lack of best practices of how to introduce and facilitate the development of effective learning and functioning within these teams in academic environments.

Methods:
To close this gap, we tailored, implemented, and evaluated team science training in the year-long Engineering Innovation in Health (EIH) program at the University of Washington (UW), a project-based course in which engineering students across several disciplines partner with health professionals to develop technical solutions to clinical and translational health challenges. EIH faculty from the UW College of Engineering and the Institute of Translational Health Sciences’ (ITHS) Team Science Core codeveloped and delivered team science training sessions and evaluated their impact with biannual surveys. A student cohort was surveyed prior to the implementation of the team science trainings, which served as a baseline.

Results:
Survey responses were compared within and between both cohorts (approximately 55 students each Fall Quarter and 30 students each Spring Quarter). Statistically significant improvements in measures of self-efficacy and interpersonal team climate (i.e., psychological safety) were observed within and between teams.

Conclusions:
Tailored team science training provided to student-professional teams resulted in measurable improvements in self-efficacy and interpersonal climate both of which are crucial for teamwork and intellectual risk taking. Future research is needed to determine long-term impacts of course participation on individual and team outcomes (e.g., patents, start-ups). Additionally, adaptability of this model to clinical and translational research teams in alternate formats and settings should be tested.

AbstractObjectives:The primary aim of this study was to assess the epidemiology of carbapenem-resistant Acinetobacter baumannii (CRAB) for 9 months following a regional outbreak with this organism. We also aimed to determine the differential positivity rate from different body sites and characterize the longitudinal changes of surveillance test results among CRAB patients.Design:Observational study.Setting:A 607-bed tertiary-care teaching hospital in Milwaukee, Wisconsin.Patients:Any patient admitted from postacute care facilities and any patient housed in the same inpatient unit as a positive CRAB patient.Methods:Participants underwent CRAB surveillance cultures from tracheostomy secretions, skin, and stool from December 5, 2018, to September 6, 2019. Cultures were performed using a validated, qualitative culture method, and final bacterial identification was performed using mass spectrometry.Results:In total, 682 patients were tested for CRAB, of whom 16 (2.3%) were positive. Of the 16 CRAB-positive patients, 14 (87.5%) were residents from postacute care facilities and 11 (68.8%) were African American. Among positive patients, the positivity rates by body site were 38% (6 of 16) for tracheal aspirations, 56% (9 of 16) for skin, and 82% (13 of 16) for stool.Conclusions:Residents from postacute care facilities were more frequently colonized by CRAB than patients admitted from home. Stool had the highest yield for identification of CRAB.

AbstractThis is a systematic review of systematic reviews of secondary health conditions, health promotion interventions, and employment in people with intellectual disabilities. Articles were included if they reported a systematic review of health and employment, secondary health conditions, and health promotion interventions for people with intellectual disabilities. The methodological quality of the included reviews was reviewed using theA MeaSurementTool toAssess systematicReviews quality rating system, a measurement tool to assess systematic reviews. Twenty-five systematic reviews were included. There was evidence that people with intellectual disabilities (ID) were at elevated risk for secondary health conditions, health promotion interventions can improve physical and mental health conditions, and employment is associated with better health-related quality of life. Health promotion intervention to help people with ID engage in health promoting behaviors can improve health and their ability to find and maintain employment.
Retrodicting large herbivore biomass for the last glacial maximum on the Palaeo-Agulhas Plain (South Africa) using modern ecological knowledge of African herbivore assemblages and rainfall

Published: May 2021

AbstractHerbivore distribution throughout Africa is strongly linked to mean annual precipitation. We use that relationship to predict functional group composition of herbivore communities during the last glacial maximum (ca. 21 ka) on the now submerged Palaeo-Agulhas Plain (PAP), South Africa. We used metabolic large herbivore biomass (MLHB) from 39 South African protected areas, in five functional groups (characterized by behavior and physiology). We examined how modern factors influenced MLHB and considered the effects of biome, annual rainfall, percentage winter rainfall, and protected area size. Overall, biome was the most important factor influencing the relationship between MLHB and rainfall. In general, MLHB increased with rainfall, but not for the grassland biome. Outside grasslands, most functional groups’ metabolic biomass increased with increasing rainfall, irrespective of biome, except for medium-sized social mixed feeder species in savanna and thicket. Protected area size was influential for medium-sized social mixed feeders and large browsers and rainfall influenced medium-sized social mixed feeders, offering some perspectives on spatial constraints on past large herbivore biomass densities. These results improve our understanding of the likely herbivore community composition and relative biomass structure on the PAP, an essential driver of how early humans utilized large mammals as a food resource.

AbstractThe present study aimed to assess the relative validity and reliability of a modified Food and Nutrition Literacy (M-FNLIT) questionnaire in primary school children in the city of Mashhad. The study was conducted in four phases. In the first step, the content and face validity of the questionnaire were evaluated by Delphi consensus as well as interviewing the students. Then, construct validity was examined using Confirmatory Factor Analysis (CFA). The internal consistency and reliability of the questionnaire were also assessed using Cronbach α and Intraclass Correlation Coefficient (ICC), respectively. Finally, a receiver operating characteristic analysis was performed to detect the cut-off scores of the M-FNLIT scale. Findings of two rounds of Delphi showed satisfactory levels of Content Validity Ratio: 0·72 and 0·92, Content Validity Index (CVI): 0·92 and 0·98, respectively. The results of CFA for domains and subscales of the M-FNLIT questionnaire including cognitive domain (understanding food and nutrition information and nutritional health knowledge) and skill domain (functional, food choice, interactive, and critical skills) indicated acceptable fit indices. M-FNLIT subscale-specific Cronbach α values ranged between 0·68 and 0·8 and ICC was 0·95 (95 % CI 0·93, 96). The final questionnaire included forty items (thirty-six Likert-type and four true-false items). FNLIT scores were categorized as low (≤ 58), medium (> 58–< 81), and high (≥ 81). The M-FNLIT questionnaire has a good level of validity and reliability to measure food and nutrition literacy in primary school children. The questionnaire can be applied in the evaluation of nutritional interventions in this age group.
