Published: February 2021

AbstractPsychosocial emergency care personnel provide voluntary psychological support directly after potentially traumatic events. During emergency responses, they experience challenging situations. However, previous quantitative studies suggest that the psychological burden of psychosocial emergency care personnel does not exceed that of the general population. This study aimed to obtain an in-depth analysis of the volunteers’ psychological reactions and resources regarding emergency responses. 36 psychosocial emergency care volunteers (12 pre-training, 12 post-training, 12 experienced) were invited to participate in semi-structured interviews. The volunteers were selected from previous cross-sectional and longitudinal studies on secondary traumatization in psychosocial emergency care volunteers. A qualitative content analysis of the transcribed interviews was performed following the principles of summary and inductive category development. We identified 845 codes which we summarized in three overarching categories: (I) reactions to emergency responses, (II) psychosocial emergency care work related resources and (III) experiences and changes in life perspective related to working in psychosocial emergency care. The volunteers described both emotional and physical reactions to emergency responses. While they perceived social support as a key coping resource and reported a greater appreciation of their own lives and their families due to their work, many volunteers also felt increased concern that something could happen to them. The volunteers’ reactions and symptoms are reasonable responses to stress and not indicative of serious impairment. Nevertheless, emergency responses are both emotionally and physically challenging. Volunteers should be carefully selected, receive regular supervision and determine the frequency of emergency responses.

Published: February 2021

AbstractDe Garengeot hernia is a rare femoral hernia defined as the presence of the appendix within the femoral hernia sac. The incidence of appendicitis in this type of hernia is a rare condition that accounts for 0.08–0.13% of all De Garengeot hernias. We describe the case of a 61-year-old woman that presented at the emergency department with a tender mass (diameter 10 × 8 cm) in the right groin region for 5 days associated with pain in lower right abdomen and accompanied by fever (38 °C). Computed tomography (CT) of the abdomen revealed the presence of a complex fluid collection with small foci of air in the right inguinal region, measuring 9 × 7 × 10 cm in the 3 orthogonal dimensions and a blind ending tubular structure extending from the caecal base into the groin mass through a narrowed neck defect, medial to the common femoral vessels. The CT scan demonstrated the suspected diagnosis of De Garengeot hernia complicated by acute appendicitis. The intra-operative findings confirmed the diagnosis. The patient was successfully managed operatively. The surgical strategy took into account the need to significantly reduce the diffusion of the infection inside the abdominal cavity. The patient was discharged on the fifth postoperative day without peri-/postoperative complications.
Animal husbandry from the Middle Bronze Age through the Iron Age in the Shephelah—faunal remains from the new excavations at Lachish

Published: February 2021

AbstractLachish (Tell ed-Duweir) is located in the southern part of the Judean foothills, known as the Shephelah, and is one of the larger and most extensively excavated multi-period sites in the southern Levant. We present the faunal results of the first three seasons of the most recent excavations, the Austrian-Israeli Expedition to Tel Lachish. The expedition focusses on two areas of the tell encompassing the Middle Bronze Age III through the Iron Age II, area S (deep section) and area P (palace area). The aims for the faunal analysis are threefold: comparing the results between the two areas, seeing how our results compare to previous analyses, and comparing Lachish to other synchronous sites in the Shephelah. We observe differences in subsistence strategies between the areas in addition to diachronic differences. Ovicaprids dominate all assemblages, but we see shifts in the sheep to goat ratio and mortality profiles through time indicating changes in subsistence strategies. Our new results largely agree with the results from previous analyses, showing the value of previous studies and their potential compatibility with newer research. A synchronic comparison of Lachish within the Shephelah shows the occupants of the site were largely self-sufficient but possibly engaged in an exchange of resources in the vicinity.
Impact of 100% organic diets on pig performance, carcass composition and carcass nutrient deposition efficiency

Published: February 2021

AbstractThe ultimate objective of organic pig production is to use ingredients of 100% organic origin in the animals’ diets. However, this approach is challenging, especially when needing to ensure adequate quantities of essential amino acids (EAAs) and protein in grower-finisher diets. The current standard is 95% organic feed ingredients, but this percentage can be increased by reducing the EAA supply or by accepting an unbalanced EAA profile. A further incentive also exists to include forages in organic diets as a way to raise dietary crude fibre content. The current study therefore investigates three organic diets (T95: 5% of non-organic origin; T100: 0% of non-organic origin and T100-CF: T100 plus an increased crude fibre level), which were offered ad libitum to 48 pigs (16 per diet) weighing 22 to 110 kg. Comparison of the three diets revealed that increasing the crude fibre content (T100-CF) reduced growth, increased total feed intake and impaired feed and protein deposition efficiency, but the unbalanced EAA profile (T100) had no effect on growth traits and protein deposition efficiency. The T100 and T100-CF pigs differed from the T95 pigs in terms of feeding behaviour traits, as they displayed more frequent but shorter feeder visits, shorter between-meal intervals and smaller meals. Increasing the fibre content with press cake ingredients raised the degree of unsaturation of the backfat and might cause problems in meat processing. In conclusion, the results revealed that pigs could cope with a mild EAA imbalance.

Abstract
Purpose
The main objective of this work is to investigate hemodynamics phenomena occurring in EVAS (Endo Vascular Aneurysm Sealing), to understand if and how they could lead to type 1a endoleaks and following re-intervention. To this aim, methods based on computational fluid mechanics are implemented as a tool for checking the behavior of a specific EVAS configuration, starting from the post-operative conditions. Pressure and velocity fields are detailed and compared, for two configurations of the Nellix, one as attained after correct implantation and the other in pathological conditions, as a consequence of migration or dislocation of endobags.

Methods
The computational fluid dynamics (CFD) approach is used to simulate the behavior of blood within a segment of the aorta, before and after the abdominal bifurcation. The adopted procedure allows reconstructing the detailed vascular geometry from high-resolution computerized tomography (CT scan) and generating the mesh on which the equations of fluid mechanics are discretized and solved, in order to derive pressure and velocity field during heartbeats.

Results
The main results are obtained in terms of local velocity fields and wall pressures. Within the endobags, velocities are usually quite regular during the whole cardiac cycle for the post-implanted condition, whereas they are more irregular for the migrated case. The largest differences among the two cases are observed in the shape and location of the recirculation region in the rear part of the aorta and the region between the endobags, with the formation of a gap due to the migration of one or both of the two. In this gap, the pressure fields are highly different among the two conditions, showing pressure peaks and pressure gradients at least four times larger for the migrated case in comparison to the post-implanted condition.

Conclusions
In this paper, the migration of one or both endobags is supposed to be related to the existing differential pressures acting in the gap formed between the two, which could go on pushing the two branches one away from the other, thus causing aneurysm re-activation and endoleaks. Regions of flow recirculation and low-pressure drops are revealed only in case of endobag migration and in presence of an aneurysm. These regions are supposed to lead to possible plaque formation and atherosclerosis.
Innovation in mining: what are the challenges and opportunities along the value chain for Latin American suppliers?
Authors: Calzada Olvera Beatriz 
Published: February 2021

AbstractThe mining industry, considered a traditional and conservative industry with respect to innovation, finds itself at a turning point due to the increasingly complex challenges, such as declining ore grades. These challenges have created an imperative to innovate. Parallel to the above, several digital innovations are being implemented in many mining operations across the globe. Not only do these provide solutions to the existing problems but also radically transform mining processes, increasing efficiency, profitability, and the ability to comply with stricter regulations. The incorporation of mature and incipient technologies into the mining industry has opened up many opportunities for long-established firms as well as knowledge-based start-ups. This includes potential suppliers in countries where mining accounts for a significant share of the GDP but the development of productive linkages remains suboptimal, as in Latin American countries. While in recent years, some suppliers in Latin America have made important contributions to increasing innovation in the mining industry, most suppliers in the region have not been able to do so. This paper provides an overview of the innovation paradigm of the mining sector from a global perspective, i.e., how innovation processes take place in countries with a long-established technological leadership in the mining sector, such as Australia and Canada. Given the importance of suppliers in this process, a special attention is paid to innovation in various stages of the supply chain. This is in order to provide a departure point for identifying windows of opportunity for equipment and service suppliers in Latin America.
Data-driven model order reduction for granular media
Authors: Wallin Erik , Servin Martin 
Published: February 2021

AbstractWe investigate the use of reduced-order modelling to run discrete element simulations at higher speeds. Taking a data-driven approach, we run many offline simulations in advance and train a model to predict the velocity field from the mass distribution and system control signals. Rapid model inference of particle velocities replaces the intense process of computing contact forces and velocity updates. In coupled DEM and multibody system simulation, the predictor model can be trained to output the interfacial reaction forces as well. An adaptive model order reduction technique is investigated, decomposing the media in domains of solid, liquid, and gaseous state. The model reduction is applied to solid and liquid domains where the particle motion is strongly correlated with the mean flow, while resolved DEM is used for gaseous domains. Using a ridge regression predictor, the performance is tested on simulations of a pile discharge and bulldozing. The measured accuracy is about 90% and 65%, respectively, and the speed-up range between 10 and 60.
Effective thermal conductivity in granular media with devolatilization: the Lattice Boltzmann modelling
Authors: Grucelski Arkadiusz 
Published: February 2021

AbstractFlow thermomechanics in reactive porous media is of importance in industry including the thermal processing of fossil fuel (coking understood as a slow pyrolysis) involving devolatilisation. On the way to provide a detailed description of the process, a multi-scale approach was chosen to estimate effective transport coefficients. For this case the Lattice Boltzmann method (LBM) was used due to its advantages to accurately model multi-physics and chemistry in a random geometry of granular media. After account for earlier studies, the paper presents description of the model with improved boundary conditions and a benchmark case. Results from meso-scale LBM calculations are presented and discussed regarding the spatial resolution and the choice of relaxation parameter along its influence on the accuracy compared with empirical formulae. Regarding the estimation of effective thermal conductivity coefficient it is shown that occurrence of devolatilization has a crucial effect by reducing heat transfer. Some quantitative results characterise the propagation of thermal front; also presented is the evolution of effective thermal conductivity. The work is a step forward towards a physically sound simulation of thermal processing of fossil fuel.
Accept and apply diversity? An exploratory study of the attitudes towards diversity of students of STEM subjects
Authors: Genkova Petia , Schreiber Henrik 
Published: February 2021

AbstractGerman universities are obligated to guarantee a fair learning environment for students with diverse features. They also must prepare students for a highly diverse working environment. This means to develop awareness for diversity and to train intercultural competence. The present study takes an exploratory look at the extent to which diversity awareness is established among science, technology, engineering, and mathematics (STEM) students and which barriers for the academic success students with a migration background perceive. To counteract discrepancies between the current state and the need for diversity awareness at universities, it identifies areas with room for improvement regarding the dealing with cultural diversity. Structured interviews with 31 STEM students were carried out and analyzed using qualitative content analysis. The interviews revealed differences in the awareness of diversity between students with and without a migration background. Results showed that there are barriers for STEM students with migration backgrounds which potentially reduce their academic success. Those barriers result from a lack of acceptance of cultural diversity and insufficient social integration and were especially apparent in insufficient language skills, orientation difficulties, and a lower degree of social integration. On the other hand, there is a need for both students with and without a migration background to promote competence and raise awareness for diversity. Furthermore, the role of social support as a resource became apparent.
Circular Agreements—Exploring the Role of Agreements and Deals as a Political Tool for a Circular Economy
Authors: Johansson Nils 
Published: February 2021

AbstractA problem for a circular economy, embedded in its policies, tools, technologies and models, is that it is driven by the interests and needs of producers, rather than customers and users. This opinion paper focuses on an alternative form of governance—agreements, which thanks to their bargaining approach brings actors from across the value chain into the policy process. The purpose of this opinion paper is to uncover and analyse the potential of such agreements for a circular economy. Circular agreements aim at increasing the circulation of materials and are an emerging form of political governance within the EU. These agreements have different names, involve different actors and govern in different ways. However, circular agreements seem to work when other types of regulations fail to establish circulation. These agreements bring actors together and offer a platform for negotiating how advantages and disadvantages can be redistributed between actors in a way that is more suitable for a circular economy. However, circular agreements are dependent on other policy instruments to work and can generate a free-rider problem with uninvolved actors. The agreements may also become too detailed and long term, which leads to problem shifting and lock-ins, respectively.
Bad Habits: Habit, Idleness, and Race in Hegel
Authors: Zambrana Rocío 
Published: February 2021

AbstractRecent discussions of Hegel's conception of second nature, specifically focused on Hegel's notion of habit (Gewohnheit), have greatly advanced our understanding of Hegel's views on embodied normativity. This essay examines Hegel's account of embodied normativity in relation to his assessment of good and bad habits. Engaging Hegel's account of the rabble (Pöbel) in thePhilosophy of Rightand Frank Ruda's assessment of Hegel's rabble, this essay traces the relation between ethicality, idleness and race in Hegel. In being a figure of refusal in its affirmation of idleness, the rabble disallows the progressive revision of the project of modernity central to Hegel's philosophy. Hegel's discussion of the rabble is thus key to assessing the production of race within Hegel's notion of ethical life.
The multilevel effectiveness of entrepreneurial leadership: A meta-analysis
Authors: Lin Qin , Yi Lingfeng 
Published: February 2021

Abstract
The effectiveness of entrepreneurial leadership (EL) at different levels has been widely recognized by scholars who have carried out substantial exploration; however, the empirical studies on the effectiveness of EL are scattered and their results are mixed. This study aims to organize these findings, advance knowledge about the multilevel effectiveness of EL and clarify the heterogeneity in the relationship between EL and effectiveness outcomes. Based on a systematic review of the extant literature and the construction of an integrated framework, this study examines the influence of EL on effectiveness outcomes at multiple levels and the moderators of this relationship through meta-analysis of 35 empirical studies including 35 independent samples. The results show that EL can improve effectiveness outcomes at different levels of organization, team and individual; cultural context obviously moderates this relationship, whereas the moderating effects of enterprise type and EL measure are all not significant. This study helps to determine the specific association of EL with effectiveness outcomes at different levels, and identify important factors influencing this relationship, which broadens the understanding of leadership effectiveness and provides certain value for enterprises to give full play to the role of EL at all levels.

Published: February 2021

AbstractBackgroundInterpersonal processes influence our physiological states and associated affect. Physiological arousal dysregulation, a core feature of anxiety disorders, has been identified in children of parents with elevated anxiety. However, little is understood about how parent–infant interpersonal regulatory processes differ when the dyad includes a more anxious parent.MethodsWe investigated moment-to-moment fluctuations in arousal within parent-infant dyads using miniaturised microphones and autonomic monitors. We continually recorded arousal and vocalisations in infants and parents in naturalistic home settings across day-long data segments.ResultsOur results indicated that physiological synchrony across the day was stronger in dyads including more rather than less anxious mothers. Across the whole recording epoch, less anxious mothers showed responsivity that was limited to ‘peak’ moments in their child's arousal. In contrast, more anxious mothers showed greater reactivity to small-scale fluctuations. Less anxious mothers also showed behaviours akin to ‘stress buffering’ – downregulating their arousal when the overall arousal level of the dyad was high. These behaviours were absent in more anxious mothers.ConclusionOur findings have implications for understanding the differential processes of physiological co-regulation in partnerships where a partner is anxious, and for the use of this understanding in informing intervention strategies for dyads needing support for elevated levels of anxiety.
RE-THINKING RACIALIZATION
Authors: Uyan Deniz 
Published: February 2021

AbstractThis paper seeks to scrutinize the most recent definition of racialization, as proposed by Adam Hochman, and interrogate its utility as a productive analytic for social scientists. Due to theoretical conflations between race and racism, and analytical conflations of groupness and category, racialization functions as a tautological descriptive rather than an agenda-setting theoretical framework for scholars studying race. The most recent definition of the concept cannot, and does not try to, account for a mechanism for the process of racialization. Such an accounting is a necessary component of any conceptualization that aims to help identify the origins of racialization. Second, in the absence of locating an agent or mechanism, the concept is tautologized: racialization, with an inability to locate a mechanism, offers itself up as the mechanism. Third, this tautologizing leads to a profound conflation of racialization offered as both a descriptive and a causal concept. Not only does this conflation halt the analytic capacity of the term as it applies to social scientific uses, but this conflation proves harmful for the anti-realist agenda as proposed by Hochman. By conflating analyses of causality with description, the latest definition of racialization unknowingly countersigns a uniquely American ideological conception of race; that is, the latest definition allows a description of the appearance of race to stand in for an explanation for race.
